    P/00/011 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT ORIGINAL TO BE COMPLETED BY APPLICANT Name of Applicant: Raven Products Pty Ltd Address for Service: A.P.T. Patent and Trade Mark Attorneys PO Box 222, Mitcham, SA 5062 Invention Title: A drop door seal for providing an even drop with quick fit connections with a spindle The following statement is a full description of this invention, including the best method of performing it known to me/us:-
    2 A drop door seal for providing an even drop with quick fit connections with a spindle FIELD OF THE INVENTION The present invention relates to drop door seal and in particular to a means for providing an even seal drop including a quick fit coupling means for connecting an 5 actuator arm to a movable spindle. BACKGROUND OF THE INVENTION A number of automatic drop door seals are currently available and have been described. The automatic drop door seals typically comprise a moveable seal member dimensioned to fit inside a channel member. The seal member includes an elongate 10 flexible portion for engagement with the threshold of the doorway. The seal member is moveable vertically between an extended position and a retracted position with respect to the bottom of the door. The automatic drop door seals are typically spring-loaded such that the seal member is biased away from the floor and operated by pressure on an activation button 15 as it bears against a doorjamb. Accordingly, as the door is opened by a few millimetres the activation button disengages with the door jamb and the elongate flexible portion is lifted clear of the floor, thereby reducing wear on the flexible portion as the door continues to be opened. A difficulty with earlier drop door seals is that operation of the seal is typically 20 from one side only, or if not then unevenly from both sides, the net result is that typically there is a sideways movement of the seal following the sideways movement of the activation button. This results in a gap forming beneath the door at one end which results in the incomplete sealing, which is important, for example, where the apparatus is being provided to seal against noise or smoke. 25 Other drop door seals, including the seal described in the Applicant's earlier Australian Patent Application 2007237192, include a rotatable spindle to which arms of respective first and second actuators are attached on opposing side of an axis of rotation of the spindle. Upon movement of the first actuator that is connected to the activation button, the spindle is configured to pivot about the axis of rotation to thereby move the 30 second actuator to the same extent but in the opposite direction.
    3 One of the limitations with this currently available system is that the spindle is connected to a spindle housing by a pin that provide pivotal engagement. Furthermore, shafts are used to pivotably connect the actuator arms to the spindle. Accordingly, a cover is required to be placed over the assembled spindle arrangement to retain the pin 5 and shafts. The currently available spindle configurations therefore have several drawbacks, being typically difficult to assemble and because of the number of small components it is easy to misplace parts during installation. It should be appreciated that any discussion of the prior art throughout the specification is included solely for the purpose of providing a context for the present 10 invention and should in no way be considered as an admission that such prior art was widely known or formed part of the common general knowledge in the field as it existed before the priority date of the application. SUMMARY OF THE INVENTION In one aspect the invention could broadly be understood to reside in a drop door 15 seal for a door, including an elongate sealing portion supported within a downwardly open channel and movable vertically between an extended position and a retracted position by way of a first actuator and a second actuator that are each connected by a respective actuator arm to a pivotable spindle positioned there between, whereby movement of the first actuator results in opposite movement of the second actuator, the 20 drop door seal including respective coupling means for connecting the actuator arms of the first and second actuators to opposite ends of the spindle, each respective coupling means comprising a spigot and cooperating socket for rotatably connecting the respective actuator arm to said spindle, the socket comprising a bore and a transverse opening wherein the bore has a larger diameter than said transverse opening, the spigot 25 being inserted through the transverse opening of the socket into the bore and inhibited from disengagement therefrom when assembled. The transverse opening of the socket may be resiliently deformable whereby the transverse opening is firstly slightly enlarged by the influence of the spigot and then once the spigot has been forced through into the bore of the socket the transverse opening 30 returns to its original size to thereby capture the spigot therein, thus providing a snap fit type connection.
    4 Alternatively the spigot has at least one flattened side such that the spigot has a first diameter that is smaller than a second diameter, the second diameter being larger than the transverse opening of the socket and smaller than the bore. This means that the spigot can be inserted through the transverse opening in a first orientation and rotate 5 within the bore such that it is inhibited from disengaging from within said bore when assembled. The spindle is preferably supported within a spindle support member and rotatable about an axis of rotation. The spindle may include first and second spigots on opposite sides of the axis of rotation and spaced apart therefrom at equal distances. 10 The first spigot being engagable with a respective socket in one of the actuator arms and the second spigot being engagable with a respective socket in the other actuator arm, wherein the movement of the actuator arm connected to the first actuator causes equal but opposite movement of the opposing actuator arm that is connected to the second actuator to thereby provide an even drop of the elongate sealing portion. 15 Each spigot may extend between first and second spaced apart side walls of the spindle. Alternatively, each spigot may be a shaft extending outwardly from the spindle configured to engage with a socket in the corresponding actuator arm, the shaft may include an enlarged free end whereby the free end provides a connection that inhibits detachment of the actuator arm from the spindle. In a further alternate form each of the 20 actuator arms may include a spigot that engages with a corresponding socket in the spindle. The socket in one form includes a generally circular bore having a larger diameter than a reduced opening of the socket. A diameter of the spigot is slightly larger than the opening of the socket and smaller than the circular bore. Accordingly, once 25 spigot engages with a respective socket the opening thereof inhibits disengagement while permitting the spigot to freely rotate within said bore. The opening of the socket may have a degree of elasticity whereby it is firstly slightly enlarged by the influence of the spigot and then once the spigot has been forced through into the bore of the socket the opening returns to its original size to thereby 30 capture the spigot therein. The spigot is inhibited from disengaging with the socket while permitting pivotable movement of the arm relative the spindle.
    5 Alternatively the coupling means may include a hook or the spindle may include a deformable portion to thereby maintain engagement between the actuator arms and spindle. In another form the spindle is generally rigid wherein the spigot has at least one 5 flattened side whereby have a first diameter of the spigot is smaller than a second diameter thereof. The spigot is inserted through the opening of a respective socket in a first orientation wherein the first diameter of the spigot aligns with the transverse opening, whereafter the spindle is rotated into a second orientation wherein the second diameter of the spigot abuts with the transverse opening to capture the spigot therein. 10 The spigots may have two flattened opposite sides and the socket may have opposing flattened sides of the opening that are dimensioned to permit the flattened side of the spigot to side there between. The bore of the socket may be generally circular and the potions of the spigots between the two flattened opposite sides may be correspondingly curved. In this way the spigot can be inserted through the opening of 15 the aperture and then the spindle and/or actuator arm rotated so that the two flattened opposite sides are out of alignment with the opening of the socket. In one form the spindle includes first and second generally parallel spaced apart side walls, a central axle member extending between the walls and including a lateral aperture for passage of an axle shaft, and first and second spigots extending between 20 the parallel side walls on opposite sides of the central axle member and at an equal distance therefrom, for attachment to said actuator arms. The spindle support member may include a body having downwardly projecting spaced apart sidewall portions. The sidewall portions include respective laterally extending generally circular apertures being coaxially aligned. 25 The spindle may be inserted between the spaced apart sidewall portions of the spindle support wherein the lateral aperture of the spindle is aligned with the apertures of the sidewall portions. An axle shaft may then be inserted therethrough to pivotably connect the spindle to the spindle support member. The sides of the spindle support member are dimensioned to fit within the upper 30 portion of the channel member of the drop door seal wherein opposite ends of the axle shaft are positioned abutting or at least adjacent respective longitudinal cross members of the channel member to thereby inhibit dislodgement of the axle shaft. The outer 6 vertical sides of the spindle support member may include shoulders for slidable engagement with the top of said cross members. The first and second actuator arms may each have a generally vertical elongate cross section and be connectable to respective spigots on the spindle, wherein the 5 actuator arms are positioned between the spaced apart sidewall portions of the spindle support member. In another form a return spring is position between at least one of said actuator arms and the spindle support member. The return spring introduces additional tension to the drop door seal to maintain the seal member in a retracted position. Furthermore 10 the return spring tends to maintain the coupling means of the actuator arms and spindle in a position that inhibits detachment. The return spring may be placed over an actuator arm before it is connected to the spigot to hold the spring in place. The spindle support member may also include protrusions extending outwardly from one end for locating an end of the return spring. 15 The spindle may be generally elongate and tapered from the central axle member towards opposing spigots. Alternatively the spindle may be generally circular or rectangular shaped. A drop door seal kit for a door including an elongate channel member, an elongate sealing portion having a flexible part that is supportable within said channel 20 member, first and second actuators, first and second actuator arms, a pivotable spindle and an activation button, wherein respective coupling means are configured to connect the first and second actuator arms to opposite ends of the spindle, the coupling means each including a spigot engagable with a socket for rotatably connecting each of said actuator arms to said spindle. 25 BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate implementations of the invention and, together with the description and claims, serve to explain the advantages and principles of the invention.

DETAILED DESCRIPTION OF THE ILLUSTRATED AND EXEMPLIFIED EMBODIMENTS There are numerous specific details set forth in the following description. 25 However, from the disclosure, it will be apparent to those skilled in the art that modifications and/or substitutions may be made without departing from the scope and spirit of the invention. In some circumstance specific details may have been omitted or 8 enlarged so as not to obscure the invention. Similar reference characters indicate corresponding parts throughout the drawings. Figures 1 and 2 illustrate a drop door seal 10 for attachment to a door 12, including a downwardly open channel member 14 having a movable drop seal member 5 16 supported therein. The downwardly open channel member 14 may be face mounted on the door 12, semi-mortised or fully mortised, as illustrated in figure 2. It should however be appreciated that the means for providing an even seal drop of the present invention could be used on drop seals of different configurations without departing from the spirit or scope of the invention. 10 The seal member 16 is moveable vertically between a retracted position and an extended position with respect to the bottom of the door 12 by way of biasing members 18, 20 that operate between the channel 14 and the seal member 16. The biasing members 18, 20 include respective leaf springs 22, 24 that are mounted to first and second actuators 26, 28 retained within an upper portion of the channel 14 by 15 longitudinally extending cross members 30. An activation button 32 being adjustably connected to actuator 26 is positioned such that it extends outwardly from within the channel 14 and clear of the side of the door 12 so that on closure of the door the activation button 32 impels actuator 26 to slide laterally towards the centre of the drop door seal 10. 20 The first and second actuators 26, 28 are movably coupled by way of actuator arms 34, 36 and pivotable spindle 38. Accordingly as the actuator 26 slides laterally across it urges actuator 28 to likewise slide inwardly towards the centre. The coupling of the first and second actuators 26, 28 means that on inward movement of the first actuator, the second actuator moves inwardly to the same extent but in the opposite 25 direction. The reverse or return action of the coupling may be assisted by the placement of a coiled return spring 40 between the actuator 26 and spindle housing 42. The actuator arms 34, 36 include opposite ends configured to pivotably engage the spindle 38 and respective actuator 26, 28. The spindle 38 is pivotal around an axle shaft 44 that extends at right angles to the direction of sliding of the actuators 26, 28. 30 The spindle 38 pivotably connected to the spindle housing 42 by axle shaft 44 therefore couples the sliding movement of the first and second actuators 26, 28, but in an opposite direction. The actuator arms 34, 36 connect to the spindle 38 at an equal distance from 9 the axle shaft 44, which ensures that the degree to which the actuators 26, 28 slide is substantially identical. An end of each leaf spring 22, 24 are mounted to respective actuators 26, 28 and the opposite end of each spring is coupled to a mount 46 attached to the seal member 5 16. The location of the mounts 46 are indicated by dotted lines in figure 1. The first and second actuators may be equidistant from a longitudinal centre of the channel 14, which may coincide with a centre of action of the springs 22, 24. The reader will appreciate that the leaf springs are generally bowed downwardly and contact the seal member, to which they are fastened, either by the mounts 46 or a fastener such as a screw, to 10 thereby enable positive retraction of the seal member 16 substantially within the channel 14. Modular connecting rods 48 may be positioned between the actuators and the actuator arms to increase the overall length of the drop door seal 10. Figure 2 illustrates the seal member 16 in the retracted position wherein the activation button 32 extends outwardly from the channel 14. On closure of the door 12, 15 the activation button 32 is pushed in by the doorjamb (not shown), which in turn pushes the first actuator 26 inwardly toward the centre of action of the spring, at the same time actuator arms 34, 36 and pivotable spindle 38 transfers the inwardly sliding movement to the second actuator 28, to ensure that both actuators move toward the centre of action of the spring to the same degree. This compression on the leaf springs 24, 24 cause 20 them to bow further downwardly, thus extending them vertically downward, to urge the seal member 16 into an extended position, as illustrated by the dotted lines in figure 2. Retraction of the leaf springs 22, 24 is the reverse of the extension, in that as pressure on the activation button 32 is released upon opening of the door, the springs are allowed to straighten out to a degree, and as such the drop seal 16 is drawn back up into the 25 channel member 14 under the influence of the spring 22, 24. As further illustrated in figures 1 and 2 the activation button 32 is adjustable by way of adjustment screw 50 and spring 51, as is known in the art. The seal member 16 includes a U-shaped extrusion 52, and elastomeric seals 54, which in the illustrated embodiment are two parallel tubular members that act together to facilitate 30 accommodation of uneven floor surfaces. The elastomeric seals 54 are retained within capturing channels 56 that extend longitudinally down the underside of the U-shaped extrusion 52.
    10 The drop door seal 10 may also include resiliently flexible skirts 58 that extend down either side of the U-shaped extrusion 52 to inhibit the ingress of dirt or other foreign matter that could foul the drop seal mechanism. The resiliently flexible skirts 58 are retaining within respective side opening C-shaped channels 60 that extend down 5 either side of the extrusion 52. Turning to figures 3 to 7 for a more detailed explanation of the drop door seal 10 of the present invention, in one embodiment the spindle 38 is supported within a spindle support member 42 by way of axle shaft 44 around which the spindle can rotate. The spindle 38 includes first and second spigots 70, 72, as illustrated in figure 4 on opposing 10 sides of a central axle member 74 delineating an axis of rotation 76, and spaced apart therefrom at equal distances. The first and second spigots 70, 72, are dimensioned to provide pivotal engagement with respective sockets 78, 80 formed on first ends of the first and second actuator arms 34, 36. The spigots 70, 72 are evenly spaced apart at diagonally opposite 15 positions relative to the pivot axis 76 so that rotation of a first of the spigots a set distance in one direction results in rotation of the second of the spigots for the same distance in an opposite direction. This means that sliding movement of the first actuator for a set distance in one direction will be translated to sliding movement of the second actuation for the set distance in the opposite direction, and this translates to a similar 20 degree of vertical displacement for both of the springs 22, 24 to thereby evenly move the seal member 16. The opposing ends of the actuator arms 34, 36 include projections 82 for engagement with a socket 84 in the end of the actuators 26, 28, or connecting rod 48. As further illustrated in figure 4 the spigots 70, 72, have a generally circular cross 25 section and are configured to be rotatably engaged by respective sockets 78, 80. In the present embodiment the sockets 78, 80 on respective actuator arms 34, 36 are openings that include respective generally circular bores 84 having a larger diameter than respective reduced opening 86. Accordingly, once the socket engages with a respective spigot the reduced opening 86 inhibits disengagement from the spindle. 30 Respective openings 86 of sockets 78, 80 frictionally engage the spigots 70, 72 to inhibit disengagement while permitting pivotable movement of the arm relative the spindle, whereby the spigot can freely rotate within the circular bore 84. The reader 11 should appreciate that the coupling means may alternatively be a hook or may include a deformable portion to thereby maintain engagement with the spigot. The spindle 38, as illustrated in figure 4, includes first and second generally parallel side walls 88, 90, a central axle member 74 extending between the walls and 5 including a lateral aperture 92 for passage of the axle shaft 44 therethrough. The first and second spigots 70, 72 extend between the parallel side walls 88, 90 on opposing side of the central axle member 74 and at an equal distance therefrom, for attachment of the actuator arms 34, 36. In the present embodiment the spindle support member 42, as illustrated in the 10 figures, includes a body 94 having downwardly and rearwardly projecting spaced apart sidewall portions 96, 98. The sidewall portions 96, 98 include respective lateral generally circular apertures 100 being coaxially aligned for passage of the axle shaft 44 therethrough to thereby delineate the axis of rotation 76 of the spindle. As illustrated in figure 4 the spindle 42 is inserted between the spaced apart 15 sidewall portions 96, 98 and the lateral aperture 92 aligned with the apertures 100 of the sidewall portions. The axle shaft 44 is then inserted therethrough to pivotably connect the spindle 38 to the spindle support member 42. The first and second actuator arms 34, 36 have a generally vertical elongate cross section, wherein the actuator arms are connected to the spindle and can be positioned between the spaced apart sidewall 20 portions 96, 98 of the spindle support member 42 within cavities 106, 108. As illustrated in figure 5, the sides of the spindle support member 42 are dimensioned to fit within the upper portion of the channel member 14 of the drop door seal 10. The channel member 14 illustrated in figure 5 is for a face mounted seal and includes an upwardly extending wing 102 for attachment to the door 12. 25 The opposing vertical sides of the spindle support member 42 may include horizontal shoulders 104 for slidable engagement with the top of the cross members 30 of the channel member 14, as further illustrated in figure 5. The ends of the axle shaft 44 are positioned within the channel member 14 either abutting or at least adjacent respective longitudinal cross members 30 to thereby inhibit withdrawal of the axle shaft 30 44. The return spring 40 is position between actuator arm 26 and the spindle support member 42, as illustrated in figure 5. The return spring 40 introduces additional tension 12 to the drop door seal to maintain the seal member in a retracted position and also tends to maintain the coupling means of the actuator arms and spindle in a position to inhibit detachment. It is envisaged that the return spring 40 will be slid over the actuator arm 34 to 5 hold the spring in place. The spindle support member 42 includes protrusions 110 for locating one end of the return spring 40. The spindle 38 may be generally elongate as illustrated in the figures and tapered from the central axle member 74 towards opposing spigots 70, 72. Alternatively, the spindle may generally circular or rectangular shaped. 10 As illustrated in figures 6 and 7 the spindle 38 is configured to pivot under the action of the actuator arm 34 connected to the first actuator 26 being influenced by the activation button 32. As the reader will now appreciate as the activation button 32 comes into contact with the door jamb the first actuator 26 and attached actuator arm 34 slide laterally across, urging the spindle 38 to pivot thereby moving actuator arm 36 in an 15 opposite direction which in turn causes actuator 28 to slide inwardly towards the centre. This in turn moves the elongate portion 16 into a lowered position. The coupling of the first and second actuators 26, 28 means that on inward movement of the first actuator, the second actuator moves inwardly to the same extent but in the opposite direction to provide an even drop of the flexible portion 16. 20 In another embodiment as illustrated in figures 8 to 10 the pivotable spindle 38 includes spigots 112, 114 having opposite flattened sides 116, 118. In this way the actuator arms 34, 36 can be slid onto the spigots 112, 114 by lining up the opening of the sockets 78, 80 with the flattened sides 116, 118 of the respective spigot, as illustrated in figure 9. The spindle 38 is then rotated to a position that the spigots 112, 25 114 are captured within respective sockets 78, 80, as illustrated in figure 10 wherein the flattened sides 116, 118 are out of alignment with openings 86 of sockets 78, 80. After assembly and during operation of the drop door seal 10 the flattened sides 116, 118 of the first and second spigots 112, 114 remain out of alignment with the opening 86 of the sockets 78, 80. This inhibits disengagement of the spigots with the 30 moveable spindle. As the skilled addressee will now appreciate the illustrated invention provides simplified assembly where the actuator arms are connected solely with a vertical clasp 13 and with no requirement to place a subsequent cover on the spindle. The invention also comprises fewer components that can be moulded with a simple cavity mould. The location of the spigots means that the movement of one of said actuator arms causes equal but opposite movement of the opposing actuator arm to thereby provide an even 5 seal drop with fewer components than currently available drop door seal systems. Various features of the invention have been particularly shown and described in connection with the exemplified embodiments of the invention, however, it must be understood that these particular arrangements merely illustrate and that the invention is not limited thereto. Accordingly the invention can include various modifications, which 10 fall within the spirit and scope of the invention. It should be further understood that for the purpose of the specification the word "comprise" or "comprising" means "including but not limited to".
