    BACKGROUND OF THE INVENTION Technical Field The present invention relates to the field of vehicle protection devices, more specifically to a protection device mounted under a vehicle body and comprising a protective member supported on a wheel set of the vehicle in an adapted manner. when using the vehicle, remove live objects from in front of the vehicle's wheels and protect the protective part from damage as the protection device encounters certain non-living objects.
    Discussion about land technology Buses are often used for various transport purposes. Buses are used e.g. to a large extent in metropolitan public transport systems. Unfortunately, there are natural dangers associated with the use of houses. Many of the most serious injuries are a result of individuals being run over by the bus, such as when a person slips and falls on the road, next to a bus wheel and the bus crushes a limb or other body part of the individual. PA correspondingly can also. a non-living object is crushed.
    To solve its problems, it has been proposed in the prior art to mount a protection device just in front of the wheels of a bus in order to establish a safety barrier between the wheels and the foremal. More specifically, as shown in U.S. Pat. 5,462,324 and 5,735,50, the edge is to mount a safety barrier to a chassis structure of a vehicle, such that a bus, with the safety barrier, includes a lower edge extending directly along a ground surface. The safety barrier is fixed in different places, such as a shaft, a frame and / or a suspension structure. The safety barrier is angled so that if an object is encountered when the bus is moving, the safety barrier forces the object out of the vehicle under a wall out of the wall from the vehicle's wheels. 2 In addition to public transport buses, school buses are used extensively to transport students for educational purposes. Of course there are other types of buses. Certainly, each of these additional types of buses, as well as other types of vehicles such as those used in the transport industry, can benefit from the incorporation of protective devices. Regardless of the vehicle type the protection device is fitted to, the device can be seriously damaged if the device collides with a non-living object, such as a curb, post, letter box or the like during use of the vehicle. Depending on the degree of damage, the protective device may not even be able to perform its intended safety task and the dam down may need to be replaced.
    Given the monetary cost and the time involved in replacing these protection devices, this scenario is not undesirable.
    Based on the above, there is a need for a more adapted mounting device for a chassis protection device for a vehicle. Above all, there seems to be a need for a safety barrier mounting device that enables protection devices to be easily mounted to a wide range of vehicles in a manner that protects the protection device from substantial damage as the vehicle inadvertently collides with a non-living object during use and thereby demands the viable and at the protection device.
    SUMMARY The present invention is directed to providing a protection device for a vehicle, such as a school or public transport bus, a tractor trailer or similar vehicle, comprising a front guard which is arranged at an angle in front of a wheel of the vehicle and which acts to push away individuals and other living objects, which are located in the wall of the vehicle, from the wall of the wheels as a safety measure, and at the same time be arranged to move movably to protect the protective device from damage when it collides with a non-living object during use of the vehicle. The protective device is, when using the vehicle, arranged sufficiently close to the ground so that if a living object is hit, the safety barrier will force the object out from under the vehicle and away from the wheelbarrow, 3 while it is mounted to shift or move into the vehicle when the device is in interference with a relatively immobile non-living object, such as a curb, post, letter box or the like. The movement of the front guard is controlled so that the guard can only move along a defined geometry axis. The front cover is further elastically mounted so that it is forced to spring back to its fully effective position after each movement caused by the contact with a non-living object. In this way, the protective device can still perform its intended protective task in full and still be protected from significant, unwanted and unintentional damage which could otherwise affect its execution.
    Additional features, features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments when read in conjunction with the drawings, in which the reference numerals refer to corresponding parts in the various views. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a public transport bus. & rail mounted front and rear protection devices in accordance with the invention; Figure 2 is an enlarged view of the assembly of the rear protection device of Figure 1; Figure 3 is an exploded view of a mounting device of a protection device in accordance with a preferred embodiment of the invention; and Figure 4 is a perspective view, similar to Figure 2, but illustrating a permissible offset arrangement of the protection device in accordance with the invention.
    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS With an initial reference to Figure 2, a vehicle 2, shown as a public transport bus, has a protection device 5 attached to it, at both the front and rear areas, the protection device being constructed in accordance with the present invention. The vehicle 2 essentially comprises a body 7 with a front end piece 8 comprising a windscreen 9 and a bumper 10. A pair of steerable front wheels are also arranged at the front end piece 8, a wheel being shown at 12 and arranged in a wheel housing 13. front side door 15 is arranged directly in front of the wheel 12. The body 7 also comprises a middle piece 17 and a rear duck piece 19. A pair of rear wheels carried the rear duck piece 19, one of the wheels being shown at 26 and being arranged in a wheel housing 30 which is formed in a side panel 33 of the vehicle body 7. Various front-to-rear windows 36 are also arranged separately along the panel 33 and vertically arranged under the roof 38. A rear door 41 is shown as arranged along the panel 33, in front of the rear wheel 26. In connection with the description of the invention it should be noted that the protection device 5 is arranged at a lower area 45, between the wheel housing 30 and the rear door 41. The protection device 5 is substantially mounted at this position under the body 7 of the vehicle 2. ch is carried up in front of the rear wheel 26 on a suitable, displaceable salt to bathe away non-living objects in an effective layer from in front of the rear wheel 26, and at the same time protect the protection device 5 from damage in a collision with certain non-living objects, during use of the vehicle 2 , which will be described in more detail below.
    It should be noted at this point that the invention will be described with respect to a preferred mounting set of the protection device 5 for the vehicle body 7, in connection with the rear wheel 26. The protection device 5 can be mounted in a corresponding manner at a position in front of the front wheel 12 which is also shown in figure As will also become more apparent below, the particular mounting of the guard device 5 to the body 7 may vary widely, in accordance with the present invention, and at the same time accommodate the adapted, displaceable configuration referred to above. Referring to the mounting of the protection device 5 in front of the rear wheel 25, as shown, Figure 2 shows an enlarged view of it below the area 45 while showing a preferred mounting device using a first mounting component 47 which is attached to the body 7 and a second mounting component 48 which is attached to the protection device 5, these two. mounting components 47, 48 are interconnected by a coupling device shown substantially at 50 in Figure 3.
    The underside of the body 7 is shown at 52, especially with respect to Figure 3. The first mounting component 47 comprises a bottom 54 from which side cradles 56 and 57 protrude straight up. The bottom 54 is formed with a plurality of spaced slots 60-63, each comprising a first end 66 and a second end 67. The slots 60 and 61 extend along a first geometry axis, while the slots 62 and 62 stack in a second geometry axis. , where these axes of geometry are parallel to each other, which should be obviously frail figure 3. The bottom 54 is also. provided with a central, elongate slot 70 with a first spirit 72 and a second spirit 73.
    An upright flange 75 of the bottom 54 projects from the second spirit 73. In the most preferred embodiment, the upright flange 75 is formed by first cutting a portion of the bottom 54 and then bending the same upward to provide the shape shown in Figure 3. A separate upright flange 75 can also be easily attached, as by welding, to the bottom 54 of the first mounting component 47. In any case, the upright flange 75 is formed with a through hole 76 as shown.
    The second mounting component 48 includes a major upper plate 80 from which a side cradle 83 hangs down and which terminates at an inward distance. The second mounting component 48 is held by an upper body portion 90 of the protection device 5. The protection device 5 thus comprises an upper body part 90 and a front protection piece 92 which is used to drive away living objects frail in front of the wheels 12 and / or 26 when the vehicle 2 is used, on a set which is edged and shown in U.S. Pat. 5,462,324 and 5,735,560, both of which are incorporated herein by reference. Since the specific construction of the front guard piece is known, it will not be described further herein. It should simply be appreciated instead that the second mounting component 48 may be attached to an upper body portion 90 on various salts. In accordance with the most preferred embodiment of the invention, the second mounting component 48 is encapsulated in the integrated molding of the upper body portion 90 on a sieve that directly matches the mounting device shown in the '560 patent referred to above. As will again become more apparent below, the specific construction and assembly of the second mounting component 48 may vary widely in accordance with the present invention so that the device shown in Figure 3 is intended to be an exemplary embodiment only.
    The plate 80 of the second mounting component 48 comprises, as shown, a plurality of spaced through passages 94-97 which are preferably threaded. The plate 80 is further also provided with a slot 99, having a shape which facilitates the erection of an upright tab member 100 with an associated through-hole 102. When the second mounting component 48 is encapsulated by the protection device 5 during manufacture, the tab member 100 extends above the upper body portion. 90, Mien 94-97 are accessible through the upper body part 90, and both the side cradle 83 and the spacer 85 provide a structural rigidity and completeness of the protection device 5.
    The first mounting component 47 is securely attached to the underside 52 of the body 7, as described above. The specific manner in which this device is designed may again vary widely according to the present invention. In a preferred embodiment, the upwardly projecting side cradles 56 and 57 are welded to the underside 52. More importantly, the manner in which the second mounting component 48 is attached to the first invention is the mounting component 47 only raises the front guard piece 92 and accommodates the adapted, displaceable movement of the guard device 5 relative to the body 7. Above all, the second mounting component 48 is positioned so that the plate 80 is arranged below the bottom 54, while the upright tab unit 100 projects into the slot 70. At the same time, the folded tails 94-97 are aligned with the respective separate slots 60-63. Gangadc fastened 108-111 are placed through the slots 60-63 which are then gang-connected to the plate 80 at the respective gangway hall 94-97. For this purpose, each threaded solid 108-111 has an associated upper washer 114 extending around respective slots 60-63 and a threaded spirit 116 which is received within the respective hall 94-97 of the plate 80. With this device the plate 80 is fixed below the bottom 54 while allowing a relatively sliding movement between a first and a second mounting component 47 and 48, where the folded solids 108-111 are movable between the first spirit 66 and the second spirit 67 of the respective slots 60-63.
    The coupling device 50 further comprises an elongate threaded fastener 119, having a head 121, a shaft 122 and a threaded spirit 123. A nut 1 felt & the elongate threaded fastener 119. A steaming unit 128 is further adapted to be mounted in the coupling between the first mounting component 47 and the second mounting component 48. The vaporization unit 128 is substantially in the form of a fader element, which is used to bias the upstanding tab unit 100 against the first end 72 of the slot 70.
    In the embodiment shown, the steaming unit 28 is in the form of a cylindrical elastic block 130 with a through bore 132. The elongate threaded fastener 119 extends through the tail 76 formed in the upright flange 75, into the through bore 132 of the block 130 and to exit through the tail 102 formed in the flap assembly 100, whereupon the nut 125 is screwed onto the threaded end 123 to secure the steaming assembly 128 between the upright flange 75 and the upright tab assembly 100.
    With this configuration, the second mounting component 48 is allowed to move relative to the first mounting component 47, while some displaceable movements are limited by the device of the steaming unit 128. In a shown most preferred embodiment, the slot 70 is arranged parallel to the slots 60-63 so that the relative movement arises along the geometry axes defined by the slots 60-63. In this way, the front guard piece 92 will assume the operative layer shown in broken lines at A in order to effectively remove live objects from in front of the vehicle wheel 26, using the vehicle 2, while also allowing the front guard piece 92 to is removed in the arrow C in the direction of the layer shown at B in Figure 4, if the front guard piece 92 abuts a non-living object with sufficient force, during use of the vehicle 2, to prevent the front guard piece 92 from being damaged. More specifically, it is shown in Figure 4 when the front guard piece 92 abuts a raised curb 140, which belongs to a sidewalk 142, which has led to the front guard piece being moved in the direction of the arrow C a distance defined by the slots 60- 63 length. In the preferred embodiment of the present invention, this length is in the order of 1-1 / 2 turns (approximately 2.5-3.8 cm). The movement of the second mounting component 48 relative to the first mounting component 47 will result in a compression of the elastic block 130 so that as soon as the front guard piece 92 is released from the curb 140, the front guard 92 will automatically move back to the operative layer shown at A. By manually adjusting the nut 125, the steaming properties of the steaming unit 128 can be easily changed.
    In order to be as effective as possible, the front guard piece 92 is preferably arranged extremely close to the wheel 26 in its operative position such as within a turn or two in front of the wheel 26. The permissible movement of the front guard piece 92 in a collision with a non-living object in in accordance with the invention occurs at an angle extending slightly in front of a transverse direction shown at D in Figure 4. Figure 4 shows that is, a transverse direction of the vehicle 2 through the arrow D and a forward direction of the vehicle 2 through the arrow E. The desired The movement between the second mounting component 48 and the first mounting component 47 is shown to be in a direction which accommodates at least a transverse movement but which prevents movement of the second mounting component 48 relative to the first mounting component 47 in a bald direction of the vehicle 2, from the operative layer. Of course, the farther away from the wheel 26 the protection device is mounted and the permissible movement dry is limited, a certain rearward movement of the front device piece 92 may be possible. In accordance with the most preferred embodiment of the invention, however, the slits 60-63 as well as the slot 70 are angled slightly forward in a transverse direction D of the vehicle 2, to provide the best salt for removing live objects frail in front of the wheel 26 and at the same time protect the front guard piece 92 from damage in the event of a collision of the safety device 5 with certain non-living objects, during use of the vehicle 2.
    In connection with the described embodiments, the protection device is generally formed as a unit in one piece which is mounted in front of one or 9 selected vehicle wheels and over a part of the chassis of the order of two feet, while it has a minimum space between the front protection device and both the ground and the intended wheel. The front cover can be made of space, rubber, urethane, aluminum or steel, although other known materials can be used to form a physical barrier that is strong enough to push a child or adult away from the front of the wheel. It would be possible to e.g. manufacture at least a part of the front cover from recycled roofing rubber or fiberglass. Different mounting devices can be used for the protection device as shown above, as long as the mounting device accommodates the adapted, displaceable movement described above, to enable the protection device to effectively remove living objects from in front of the wheel and at the same time allow the protection device to move back and forth automatically. relative to the vehicle body, when a force is exerted on the protection device by a non-living object, during normal use of the vehicle. Although the description refers to preferred embodiments of the invention, it is to be understood in any case that various changes and / or modifications may be made to the invention without departing from the spirit thereof. The invention is essentially only intended to be limited by the scope of the following claims.
