    [0001] The present invention relates to a clamp used in a fire support system for the head of the fire sprayer. BACKGROUND OF THE INVENTION
    [0002] A typical automatic fire extinguisher system includes a pipe network that conducts fire suppression fluid, for example, water, to each room in a building. Flue sections conduct the fluid from the pipes to the fire sprayer heads strategically located in different rooms. The position and orientation of each fire sprayer head is typically held in place by the support assembly. When the room reaches a high temperature due to a fire, the head of the fire sprayer is activated, allowing the flow of the fire suppression fluid to be directed to the intended coverage area. During operation, the fluid pressure in the fire sprayer head can be as high as 175 psi, generating significant back pressure on the fire sprayer head support system. The support assembly is used to hold the fire sprayer head firmly in place during operation.
    [0003] Some known fire sprayer support assemblies are designed to be attached to a ceiling frame by fasteners such as screws or bolts which must be tightened using special tools in a lengthy process. SUMMARY

The support assembly includes a leg configured to extend transversely across each pair of adjacent legs of the spaced parallel beams. The leg includes a transverse portion and a lever clamp assembly for connecting and supporting one end of the transverse portion of the leg to a corresponding portion of the beams. The lever clamp assembly includes a first plate that extends from and generally perpendicular to the transverse portion of the leg, a second plate that extends generally parallel to the first plate, the second plate being rotatable with respect to the first plate. The first plate and the second plate are configured to be arranged on the opposite sides of a corresponding portion of the beams in such a way that the plates cross the beam. The lever clamp assembly also includes a lever assembly. The lever assembly includes a rod that passes through the corresponding rod openings on each of the first and second plates and a lever swiveled to one end of the rod, the lever including a flesh surface disposed adjacent to the first plate, such that the lever assembly is configured to reduce the spacing between the plates during the actuation of the lever, so that the leg is caught in the beam.

    [00035] Referring to Fig. 1, a fire sprayer system 100 includes several fire sprayer support assemblies 302 mounted within a ceiling 104 that has a ceiling support frame 106 formed by a set of frame sections rectangular 108 (a frame section 108 is shown with crossed lines). The ceiling support frame 106 can be a suspended ceiling to support a decorative panel (not shown) within each section of rectangular frame 108. For example, the ceiling support frame may consist of beams 202 with T-bars suspended from from an overlapping structure of the building using, for example, flexible wire, and they can be configured according to international ASTM standards. Standards may include, but are not limited to, those described in one or more designations C635, C636 and E580, which are hereby incorporated by reference. In order to protect the fire room, the fire sprayer system 100 is most commonly located above the ceiling support frame, but it can also reside on the floor or on one or more walls.
    [00036] Fire sprayer system 100 may include supply pipes 110 as part of a fire suppression fluid delivery system. The fluid distribution system can be dedicated to fire suppression, or it can also distribute water for other functions (for example, inside the building). The fire sprayer system 100 also includes the flexible mounting of the fire sprayer 112 that conducts the fire suppression fluid, for example, water from the supply pipes 110 to the head of the fire sprayer 114. For example, the flexible fire sprayer assembly 112 may include a socket at the inlet 116o which connects the assembly 112 to the supply pipe 110, and a flexible conduit 118 which extends between the socket at the inlet 116 and an end of a rigid head of the sprayer fire that fits 120. Flexible duct 118 can be formed of corrugated metal with the braided metal cover, and welded either by fitting the inlet 116 or by the fitting of the fire sprayer head 120, or it can be formed by corrugated metal and connected both by the fitting in the inlet and by the fitting of the fire sprayer head 120 using screw connectors. Assembly 112 may also include the fire sprayer head 114 which is connected to the other end of the fire sprayer head 120. When the room reaches high temperatures, the fire sprayer head 114 is activated and a flow of fire suppression fluid is directed into the room to extinguish the fire.
    [00037] Each fire sprayer support assembly 302 secures a fire sprayer head 114 in a predetermined position within an associated position of the rectangular roof frame sections 108. In order to function effectively, the fire sprayer head 114 must be held firmly in place during operation. Due to the significant counter pressure of the fluid flowing through it, the head of the fire sprayer 114 is subjected to tremendous lateral forces, of rotation and torsion, which are capable of changing the position of the head of the fire sprayer 114, thereby causing the fluid to be directed away from the intended target. The fire sprayer support assembly 302 is configured to resist the movement of the fire sprayer head 114 by distributing forces over the spaced points along the periphery of one of the rectangular frame sections 108.
    [00038] With reference to figures 2 and 3, an exemplary embodiment of a fire sprayer support assembly 302 is mounted within a ceiling support frame 106, which, in this example, is a rigid T-bar.
    [00039] The fire sprayer support assembly 302 includes a leg 304 that includes a transverse portion 305, and the lever clamp assemblies 308 and seating frames 320 positioned at ends opposite the transverse portion 305. The support assembly 302 it is rigidly attached to the ceiling support frame 106 by the clamp with the lever mounts 308 and stabilized by the seating frames 320. The lever clamp mounts 308 are configured to fit with the beam 202 of a ceiling support frame 106 and attaching the fire sprayer support assembly 302 to beam 202, as discussed just below.
    [00040] The transverse portion 305 of the leg 304 generally extends parallel to the ceiling support frame 106 and is dimensioned to extend along a pair of parallel parallel T-beam beams 202. The lever clamp assemblies 308 and the seating frames 320, provided at opposite ends of the transverse portion 305, come into contact with the beam 202 at various points ensuring that the forces in the fire sprayer support assembly 302 are distributed over the portion of the frame section of the fire ceiling 108. As a result, the stability of the fire sprayer support assembly 302 is guaranteed and the fire sprayer head 114 is prevented from moving or rotating in any direction during operation.
    [00041] The transverse portion 305 of the leg 304 includes a central slot 310 that is dimensioned to receive the head of the fire sprayer 120, and is elongated crosswise to the width of the leg 304 to allow adjustment of the position of the head fitting. fire sprayer head 120 within the ceiling frame section 108. The cross section 305 also includes side slots 312 sized to receive a screw for mounting the wheel hub assembly 314. Side slots 312 are arranged between the central slot 310 and the side parts 316, 318 of the leg 304, and are elongated across the width of the leg 304 to allow adjustment of the location of the screws within the leg 304. Adjusting the position of the head of the fire sprayer 120 within of frame section 108 is unlimited.
    [00042] In the illustrated embodiment, a wheel hub assembly 306 is used to secure the fire sprocket head fitting 120 to the fire sprayer support assembly 302. The wheel hub assembly 306 includes a primary support 1102 o which engages on the leg 304 of the support assembly 302, and a secondary support 1202 which is pivotally connected to the primary support 1102, as described in copending US patent application 12 / 784,286, which is incorporated herein by reference. Secondary support 1202 rotates with respect to primary support 1102 about a pin 1106 between an open position (not shown) and a closed position (shown). The primary support 1102 and the secondary support 1202 are formed having cut portions 1104, 1204, such that when the secondary support 1202 is in the closed position in relation to the primary support 1102, the cut 1104 formed in the primary support 1102 cooperates with the cut 1204 formed in the secondary support 1202 to define the opening of the wheel center 1150 configured and to receive and firmly secure the fitting of the fire sprayer head 120. When the wheel hub assembly 306 is attached to the leg 304, the opening of the wheel center 1150 coincides with the central slot 310. In addition, the wheel hub assembly 306 includes a locking mechanism 1108 that selectively connects primary support 1102 to secondary support 1202, and an adjustment mechanism 1110 provided over the primary support 1102 is used to maintain the position of the fire sprocket head 120 within the wheel center opening 1150.
    [00043] With reference to Fig. 4, an exploded view of the lever clamp assembly 308 is shown. The lever clamp assembly 308 is the leg portion 304 that connects to the ceiling support frame 106 and can be attached to the ceiling support frame 106 by attaching two plates 404, 406 together around beam 202. A Lever clamp assembly 308 includes a first plate 404, a second plate 406, and a lever assembly 408 that connects the first plate 404 to the second plate 406, and determines their relative positions, as described below.
    [00044] In this embodiment, the first plate 404 extends integrally from and is generally perpendicular to the transverse portion 305 of leg 304 of the fire sprayer support assembly 302 and has a flat, rectangular shape. The first plate 404 includes a stem opening 412 which is arranged between a fixed edge 402 and a free edge 428 of the first plate 404. The stem opening 412 is not threaded and has a diameter slightly larger than the outside diameter of the stem 410. The first plate 404 includes a tongue opening 422 which is arranged between the fixed edge 402 of the first plate 404 and the opening of the stem 412. In addition, shaped protuberances with triangular tip 424 extend inwardly towards the second plate 406 from the free edge 428. For example, a protuberance 424 can be provided adjacent the respective side edges 427, 429 of the first plate 404. The pointed protuberances 424 generally extend parallel to the transverse portion 305 of the leg 304 and are configured to engage the corresponding beam 202 when the lever clamp assembly 308 is activated.
    [00045] The second plate 406 is hinged and extends from the first plate 404. The second plate 406 is not permanently attached to the fire sprayer support assembly 302, in such a way that it can be separated from the lever clamp assembly 308. The second plate 406 includes an articulated rim 438 at one end, and the free rim 434 at the opposite end. A tongue 430 extends from the hinge edge 438. The tongue 430 is a curved member and is configured to be received within the tongue opening 422 to provide the hinged connection between the second plate 406 and the first plate 404. In particular, the second plate 406 rotates on the curved surface of the tongue 430 in relation to the first plate 404. In addition, its curved shape maintains the tongue 430 in the tongue opening 422.
    [00046] In some embodiments, the second plate 406 may include reinforcement projections 432. Reinforcement projections 432 extend perpendicularly and between the free edges 438, 434 of the second plate 406 to ensure that the second plate 406 does not flex when lever clamp assembly 308 is attached to beam 202. Alternatively, second plate 406 can be configured to be of sufficient thickness to prevent flexing when lever clamp assembly 308 is attached to beam 202.
    [00047] In addition, the second plate 406 includes a threaded shank opening 413 and a protrusion 426. The protrusion 426 is located between the middle portion of the plate and the free edge 434, and extends inwardly towards the first plate 404 along the width of the free edge 434 of the plate 406. The protrusion 426 fits into the beam 202 when the lever clamp assembly 308 is activated. In some embodiments, the second plate 406 may include additional protrusions similar to the patterned protrusions with triangular tip 424 included in the first plate 404.
    [00048] Lever assembly 408 includes a threaded stem 410 that passes through the corresponding stem openings 412, 413 on each plate 404, 406, and a lever 418. Lever 418 includes a cam surface 420. Lever 418 is pivotally connected to the end of the stem 410 by a pin 436 and the axis of rotation 437 of the lever 418 is eccentric with respect to the periphery of the meat surface 420. The meat surface 420 of the lever 418 has a generally semicircular peripheral shape. When the lever clamp assembly 308 is mounted, the cam surface 420 touches the outwardly facing surface 440 of the first plate 404. Lever 418 rotates around pin 436 between an open position and a closed position, as discussed below .
    [00049] The stem 410 extends through both the opening of the stem 412 of the first plate 404 and the opening of the stem 413 of the second plate 406. The threads of the stem 410 are configured to fit the threads of the opening of the stem 413 of the second plate 406. By turning the threaded rod 410, the amount of space between plates 404, 406 can be adjusted to make the clamp connection more secure.
    [00050] With reference to Fig. 5a, although the meat surface 420 is generally semicircular, it can be seen in Fig. That in fact, the periphery of the meat surface 420 deviates from the circular shape. In particular, the meat surface 420 is formed by different sections: the section between points a and b (a-b), the section between points b and c (b-c), and the section between points c and d (c-d). Each section is formatted to perform a specific function while operating the 408 lever clamp assembly.
    [00051] The section a-b of the meat surface 420 is generally flat in shape and ensures that lever 418 is freely movable and adjustable when lever clamp assembly 408 is in the open position as in Fig. 5a.
    [00052] When lever assembly 408 is activated, the cam surface 420 of lever 418 rotates around the eccentric axis of rotation 437 and creates a cam action against the first plate 404. The cam action is facilitated by the shape of the section bc of the meat surface 420. During the actuation of lever assembly 408, section bc gradually increases the distance between the contact point of the meat surface 420 and the outward surface 440 of the first plate 404 and the eccentric axis of rotation 437 of lever 418. This cam action pulls stem 410 towards lever 418 along axis A, thereby reducing the spacing between plates 404, 406 by pulling the second plate 406 towards the first plate 404. The extension of the meat action is determined by combining the distance between the periphery of the bcd section of the meat surface 420 and the location of the pin 436. The reduction in spacing makes the plates 404, 406 and their corresponding protuberances 424, 426 fit ixem in beam 202.
    [00053] The distance between the periphery of section c-d of the meat surface 420 and the eccentric axis of rotation 437 is designed to be slightly less than the distance of section b-c. Turning lever 418 such that the section cd touches the outward facing surface 440 of the first plate 404 causes the distance between the contact point of the meat surface 420 and the outward facing surface 440 of the first plate 404 to slightly decrease. in relation to the eccentric axis of rotation 437. Decreasing this distance locks lever 418 in place. Therefore, the fire sprayer support assembly 302 is attached to a ceiling support frame 106.
    [00054] Again, with reference to Fig. 4, the seating frame 320 is shown. The seating frame 320 provides lateral stability for the fire sprayer support assembly 302 and determines the height 210 of the lever clamp assembly 308 in relation to beam 202. The seating frame 320 is generally U-shaped and includes a first seat frame member 444 and a second seat frame member 446, each including a corresponding protrusion 448, 450, corresponding fixed edges 458, 460 and corresponding free edges 462, 464. A connecting member 452 extends from from an inner edge 454 of the first member of the seating frame 444 to an inner edge 456 of the second member of the seating frame 446 so that the total width of the seating frame 320 corresponds to the width of the leg 304. As shown in the direction of the arrow A, the seating frame 320 generally surrounds the periphery of the first plate 404.
    [00055] In this embodiment, the first member of the seat frame 444 and the second member of the seat frame 446 extend integrally from and in the generally normal direction with respect to the transverse portion 305 of the leg 304 of the fire sprayer support assembly 302 to be generally parallel to the first plate 404. However, the first member of the seating frame 444 and the second member of the seating frame 446 are not coplanar with the first plate 404, but are offset inwardly relative to the first plate 404 The first and second members of the seating frame 444, 446 are positioned adjacent the opposite side sides 316, 318 of the transverse portion 305 of the leg 304 of the fire sprayer support assembly 302.
    [00056] The protrusions 448, 450 are arranged in the median portion of each of the members of the seating frame 444, 446 between the fixed edges 458, 460 and the free edges 462, 464. The protrusions 448, 450 extend away and perpendicular to the transverse portion 305 of the leg 304. The protrusions 448, 450 also extend along the width of the corresponding free edges 462, 464. When the fire sprayer support assembly 302 is positioned around beam 202, the protrusions 448, 450 fit into beam 202 from the side of beam 202 opposite the first plate 404.
    [00057] Connecting member 452 extends between the inner edge 454, 456 of each of the seating frame members 444, 446. Connecting member 452 provides rigidity for the seating frame 320. When in use, the connecting member connector 452 and the seat frame members 444, 446 rest on the beam, determining the height 210 of the lever clamp assembly 308 in relation to the beam 202.
    [00058] During installation of the fire sprayer system 100, the seat frame members 444, 446 and the connecting member 452 of the seat frame 320 interact with beam 202 to secure the fire sprayer support assembly 302 on beam 202 and to maintain the alignment of the fire sprayer head socket 120 by preventing the fire sprayer support assembly 302 from rotating around the lever clamp assembly 308.
    [00059] With reference to Fig. 5a, the lever clamp assembly 308 is shown in the open position. In the open position, the cam surface 420 of lever 418 is not engaged with the first plate 404 and the distance between the axis of rotation 437 of pin 436 and the surface of lever 418 closest to the first plate 404 is relatively small. Thus, stem 410 was not pulled toward lever 418 through the opening of stem 412 of the first plate 404. The distance between lever 418 and the second plate 406 can be adjusted by rotating stem 410 around its longitudinal axis inside opening 413. Depending on the adjustment on the stem 410 inside opening 413 of the second plate 406, a space is provided between the first and second plates 404, 406 and the lever clamp assembly 308 can be positioned in relation to the beam 202 or removed from it, if desired.
    [00060] With reference to Fig. 5b, the lever clamp assembly 308 is shown in the closed position. In the closed position, the cam surface 420 of lever 418 is engaged with the first plate 404 and the distance between the axis of rotation 437 of pin 436 and the cam surface 420 is relatively large. In this way, stem 410 is pulled towards lever 418 through the opening of stem 412 of the first plate 404. The stem 410 pulls the second plate 406 towards the first plate 404, thereby reducing the spacing between the first and second plates 404, 406 and securing lever clamp assembly 308 to beam 202.
    [00061] The fire sprayer support assembly 302, described above, is secured within a ceiling frame 106 using a quick release type clamp with lever 308 that allows installers of the fire sprayer system to quickly install , position and uninstall the fire sprayer support assemblies 302. In this way, the amount of time and effort required to install or modify a fire sprayer support assembly will be reduced in relation to the prior art support assemblies, which are attached to a ceiling frame 106 by screws or bolts.
    [00062] The clamps are designed to hold the firebreaker head firmly in place during operation from the resistant side, by rotation and torsional forces. The holding force of the lever clamps 308 in combination with the contact surface made possible by the use of plates 404, 406 and the protrusions 424, 426 which hold the beams 202 is sufficient to prevent the unwanted release of the bracket support assembly fire 302. In addition, the seating frame 320 ensures that the fire sprayer support assembly 302, and thereby the fire sprayer head socket 120 remains aligned and stable during the operation of the fire sprayer system. 100.
    [00063] Although the first and second plates 404, 406 are described as being two separate members, the lever clamp assembly 308 is not limited to this configuration. For example, in an alternative embodiment (not shown), the second plate 406 can be formed as a partial cut portion of the first plate 404 that is folded back and over the portion of the first plate 404. Instead of being hinged to the first plate 404 as described above, the second plate 406 extends integrally from the first plate 404 and can rotate with respect to the first plate 404 around a fixed edge due to the flexibility of the material from which the plate is manufactured.
    [00064] With reference to figures 6 and 7, an alternative embodiment of a fire sprayer support assembly 602 is mounted within a ceiling support frame 106, which, in this example, is a T-bar type grid. .
    [00065] The fire sprayer support assembly 602 includes a leg 604 and a wheel hub assembly 606. The opposite ends of the leg 604 include lever clamp assemblies 608 through which the cross portion 605 of the leg 604 is supported . The bracket assembly 602 is rigidly attached to the ceiling bracket frame 106 by the lever clamp mounts 608. The lever bracket mounts 608 are configured to fit with the beam 202 of a ceiling bracket frame 106 and secure the support mounting of fire sprayer 602 on beam 202, as discussed below.
    [00066] The cross section 605 of the leg 604 is in the form of a bar that generally extends parallel to the ceiling support frame 106. The cross section 605 of the leg 604 is also dimensioned to extend along a pair of adjacent beams and parallel T-bar type 202. The leg 604 of the fire sprayer support assembly 602, which includes the lever clamp assemblies 608, is configured to withstand the forces applied to the head of the fire sprayer 114 during its operation . As a result, the stability of the fire sprayer support assembly 602 is guaranteed and the fire sprayer head 114 is prevented from moving or turning in any direction during operation.
    [00067] The leg 604 supports a wheel hub assembly 606 that has a shape and operation similar to the wheel hub assembly 306 previously described.
    [00068] With reference to Fig. 8, an exploded view of the lever clamp assembly 608 is shown. The lever clamp assembly 608 includes a base 702, a first plate 704 and a second plate 706. Base 702 generally extends parallel to the transverse portion 605 of leg 604. Each plate 704.706 extends from the opposite ends and generally from perpendicular to the base 702, forming a U-shaped member. The lever clamp assembly 608 also includes a lever assembly 708. The lever assembly 708 includes a threaded rod 710 that passes through the corresponding rod openings 712, 713 on each plate 704, 706, and a lever 714 pivotally connected to one end of the stem 710. The lever 714 includes a meat surface 716 which is in contact with the first plate 704. In addition, the first plate 704 and the second plate 706 includes an opening leg 738 which receives the cross section 605 of leg 604 of the fire sprayer support assembly 602.
    [00069] The first plate 704 includes a base end 721 joined to the base 702, and a free end 724 that is opposite the base end 721. An opening leg 738 is arranged close to the base end 702 of the plate 704 and configured to accommodate the size and shape of the cross section 605 of the leg 604 of the fire sprayer support assembly 602. In addition, the first plate 704 includes a stem opening 712 arranged between the leg opening 738 and the free edge 724. The opening of the stem 712 is not threaded and has a larger diameter than the outer diameter of stem 710.
    [00070] The first plate 704 also includes a protrusion 720 disposed on the free edge 724 of plate 704. The protrusion 720 extends inward and towards the second plate 706 over the entire width of the first plate 704. The protrusion 720 generally extends perpendicular to the first plate 704. The first plate 704 can also include reinforcement projections that extend perpendicular to the base 702 along the length of the first plate 704 between the base end 721 and the free end 724 and which are configured to prevent plate 704 from flexing. Alternatively, the first plate 704 can be configured to be thick enough to prevent bending when lever clamp assembly 308 is attached to beam 202. The second plate 706 is a substantially mirrored image of the first plate 704. In particular, the second plate 706 includes an opening leg 738 arranged near the base end 702 of the plate 706 and is configured to accommodate the cross section 605 of the leg 604 of the fire sprayer support assembly 602. In addition, the second plate 706 includes a stem opening 713 disposed between opening leg 738 and free edge 730. However, the second plate 706 differs from the first plate 704 in that the opening 713 is threaded, the threads are configured to fit with the stem threads 710. The second plate 706 also includes a protrusion 722 arranged on the free edge 730 of the plate 706. The protrusion 722 extends inwardly towards the first plate 70 4 and over the entire width of the second plate 706. The protrusion 722 generally extends perpendicular to the second plate 706. The second plate 706 can also include reinforcement projections 728 that extend perpendicular to the base 702 along the length of the second plate 706 between the base and the free ends 729, 730, and which are configured to prevent plate 706 from flexing. Alternatively, the second plate 706 can be configured to be thick enough to prevent bending when lever clamp assembly 308 is attached to beam 202.
    [00071] The lever assembly further includes a lever 714 arranged on one end of the stem 710. The lever 714 is pivotally connected to the end of the stem 710 by a pin 732 and the axis of rotation 737 of the lever 714 is eccentric with respect to to the periphery of the meat surface 716. The meat surface 716 of the lever 714 has a semicircular peripheral shape. When lever clamp assembly 608 is mounted, the cam surface 420 touches the outwardly facing surface 740 of the first plate 704. Lever 714 rotates around pin 732 between an open position and a closed position, as described above in with respect to figures 5a and 5b.
    [00072] The stem 710 extends through both the stem opening 712 of the first plate 704 and the threaded stem opening 713 of the second plate 706. The threads of the stem 710 are configured to fit the threads of the threaded stem opening 713 of the second plate 706. By turning the threaded rod 710, the amount of space between plates 704, 706 can be adjusted to make the clamp connection more secure.
    [00073] The meat surface 716 of lever 714 has the same shape and functionality as the meat surface 420 described in the first embodiment.
    [00074] When lever assembly 708 is activated, the cam surface 716 of lever 714 rotates around the eccentric axis of rotation 737 and creates a cam action against the first plate 704. The cam action reduces the spacing between the the first plate 704 and the second plate 706 pulling the second plate 706 towards the first plate 704. The reduction in spacing makes the plates 704, 706 and its corresponding protrusions 720, 722 fit into beam 202. Thus, the lever clamp assembly 708 is attached to a ceiling support frame 106.
    [00075] The U-shaped member including the base 702, the first plate 704 and the second plate 706 of the lever clamp assembly 608, is secured to the cross portion 605 of the leg 604 by a fastener such as a positioning screw 734 which is received at the opening of the positioning screw 736 on the base 702. The opening of the positioning screw 736 is generally located centrally on the base 702. The lever clamp assembly 608 can be positioned along the length of the cross section 605 of the leg 604 by loosening the positioning screw 734 and sliding the lever clamp assembly 608 along the length of the transverse portion 605 of the leg 604 in the desired direction. The lever clamp assembly 608 is held in the desired position on the cross portion 605 of the leg 604 by rotating the positioning screw 734 to the point where one end of the screw 734 is pushed against the surface of the cross portion 605 of the leg 604.
    [00076] The fire sprayer support assembly 602 described above is secured within a ceiling frame 606 using a quick release type clamp with lever 608 which allows installers of the fire sprayer system to quickly install , position and uninstall the fire sprayer support assemblies 602. In this way, the amount of time and effort required to install or modify a fire sprayer support assembly will be reduced in relation to prior art support assemblies, which are attached to a ceiling frame 106 by screws or bolts.
    [00077] The lever clamps 608 are designed to hold the fire sprayer 114 head firmly in place during operation from the resistant side, by rotation and torsional forces. The holding force of the lever clamps 608 in combination with the contact surface made possible by the use of plates 704, 706 and the protrusions 720, 722 which hold the beams 202 is sufficient to prevent the unwanted release of the bracket support assembly of fire 602.
    [00078] With reference to figures 3 to 5, the method of mounting a fire sprayer support assembly 302 on a ceiling support frame 106 will be described. The ceiling support frame 106 can consist of T-beam beams 202. First, the person installing the fire sprayer system 100 turns lever 418 of each of the lever clamp assemblies 308 to the open position as shown in Fig. 5a.
    [00079] With the lever clamp assemblies 308 in the open position, the lever clamp assemblies 308 of the fire sprayer support assembly 302 are fitted over the corresponding beams 202 of the ceiling support frame 106. The fitting of the assemblies lever clamp 308 on beams 202 may include manually spreading plates 404, 406 of lever clamp assemblies 308 by rotating the second plate 406 on tongue 430 to obtain adequate spacing for receiving beam 202.
    [00080] When the fire sprayer support assembly 302 is in the desired location within the ceiling support frame 106, the spacing between the plates can be adjusted by rotating the threaded rod 410. Then, lever 418 is rotated to the closed position as shown in Fig. 5b.
    [00081] Closing the clamp assembly with lever 308 causes a meat action between the meat surface 420 and the first plate 404. The meat action pulls the stem 410 towards the lever 418, thereby also pulling the second plate 406 towards the first plate 404. As plates 404, 406 are pulled together, protrusions 424, 426 fit into the beam, securing the fire sprayer support assembly 302 to the ceiling support frame 106.
    [00082] The alternative modality of the fire sprayer support assembly 602 is generally used in the same way. However, the position of the lever clamp assemblies 608 can be adjusted along the length of the transverse portion 605 of the leg 604 before they are fitted over the beams 202. This adjustment is made by loosening the positioning screw 734 and sliding the lever clamp 608 is mounted along the length of the transverse portion 605 of the leg 604 in the desired direction. The lever clamp assembly 608 is held in the desired position on the cross portion 605 of the leg 604 by rotating the positioning screw 734 to the point where one end of the screw 734 is pushed against the surface of the cross portion 605 of the leg 604.
    [00083] A selected illustrative embodiment of the invention has been described above in some detail. However, it should be understood that only the structures deemed necessary have been described here to facilitate the understanding of the present invention. Other conventional structures, and those additional and auxiliary components of the system, are deemed to be known and understood by those skilled in the art. In addition, although an operational example of the present invention has been described above, the present invention is not limited to that operational example described above, and various model changes can be made without departing from the scope of the present invention as described in the claims.
