Description

The present invention relates to a lateral reflector of a vehicle.

Trucks are equipped with side reflectors on the sides of the vehicle, based on the safety standards of road vehicles. For trucks, vans and dump trucks are installed according to the end user's application, but the work to install the equipment on the chassis of the truck is often carried out by the equipment manufacturer. In such a case, the vehicle manufacturer temporarily attaches a side reflector to the chassis frame (side rail) of the vehicle, and ships the vehicle in a state where it is not mounted to the mounting manufacturer. The side reflector temporarily installed by the vehicle manufacturer is removed when it is installed by the equipment manufacturer, and after the installation, the side reflector is finally installed by the equipment manufacturer.

As a conventional technique for truck reflectors (Patent Document 1), the width of a chassis with a cab is sufficiently confirmed at night to prevent self-rear-end collisions, etc., thereby improving safety and expanding and contracting stays. It is disclosed that reflectors are attached to both ends and a stay whose length is adjusted according to the vehicle width of the chassis with a cab is detachably attached to the rear end of the chassis with a cab via a magnet.

The above-mentioned safety standards for road transport vehicles stipulate the mounting position of side reflectors, but trucks have many variations in length, and various parts are mounted on the chassis frame. It is necessary to deal with a wide variety of vehicles, and it takes a lot of time for design work such as setting the mounting position. Further, the side reflector temporarily mounted by the vehicle manufacturer is required to be detachably attached so that it can be removed by the mounting manufacturer. Therefore, a hole is made in the chassis frame, and the side reflector is attached by bolts and nuts, but it takes a lot of man-hours to make a hole in the chassis frame.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the work of setting the mounting position and the man-hours required for mounting the side reflector when the vehicle manufacturer mounts the side reflector. The purpose is.

The present invention has been made to solve at least a part of the above-mentioned problems, and can be realized as the following aspects or application examples.

(1) A side reflector of a vehicle mounted on a chassis frame having a U-shaped cross section consisting of an upper piece, a lower piece, and a vertical piece connecting the upper piece and the lower piece. The vessel is composed of a reflective member directed to the outside of the vehicle and a connecting member to which the reflective member is attached and supported by the chassis frame. The connecting member is a side piece portion abutting on the outer surface of the vertical piece. A support portion that is connected to the side piece portion and to which a reflective member is attached, a horizontal piece portion that is branched from the side piece portion and abuts on the upper surface of the upper piece, and a horizontal piece portion that is provided on the horizontal piece portion and engages with the end portion of the upper piece. It is composed of a claw portion that is jointly supported.

Therefore, when the side reflector is mounted on the chassis frame, it can be mounted without providing a mounting hole in the chassis frame, so that the man-hours required for mounting the side reflector can be reduced.

FIG. 1 is a schematic view showing a mounting position of a side reflector according to an embodiment of the present invention on a vehicle. The vehicle will be described assuming an automobile such as a bus or a truck.

The schematic diagram shown in FIG. 1 shows a side surface of a vehicle 1, which is, for example, a truck. This state represents the state before the vehicle is manufactured by the vehicle body manufacturer and is manufactured by the vehicle body manufacturer. The vehicle 1 is provided with a cab 20 having a driver's seat on which the driver is boarding, a chassis frame 10, wheels 40A, 40B, and 40C.

In the case of industrial automobiles such as trucks, the erection is to equip the chassis with a so-called cab with equipment suitable for the purpose such as a loading platform. In an industrial vehicle to be mounted, the process may be divided such that the basic vehicle is manufactured by the vehicle manufacturer and the mounting on the vehicle is performed by the mounting manufacturer.

A plurality of side reflectors 30 are attached to the side surface of the chassis frame 10. Although only the left side surface in the vehicle traveling direction is shown in FIG. 1, a plurality of side reflectors 30 are attached at the same positions on the opposite side. The mounting position and number of the side reflectors 30 are determined for each type of vehicle based on safety standards and the like. The side reflector 30 is finally installed by the erection maker, but is required when the vehicle maker drives and transfers the side reflector from the vehicle maker to the erection maker before mounting.

FIG. 2 is a front view and a cross-sectional view of the side reflector according to the embodiment. The side reflector 30 includes a reflecting member 31 that reflects light and a connecting member 32 that connects the reflecting member 31 to the chassis frame 10.

The reflective member 31 is, for example, a retroreflective member, and is a material that reflects light emitted from a light source in the direction of the light source again.

The chassis frame 10 is composed of a pair of rod-shaped frames having a U-shaped cross section. It is also called a ladder frame because it has a ladder shape. One of the frames has a U-shaped cross section, and the upper piece 11 (11L), the lower piece 13 (13L), and the upper piece 11 (11L) and the lower piece 13 (13L) are connected to each other. It is composed of a vertical piece 12 (12L) facing outward. The open side of the frame is arranged so as to face each other, and a symmetrical frame exists on the opposite side. Therefore, in this figure, the cross section of one of the pair of frames is shown.

The connecting member 32 that connects the side reflector 30 to the chassis frame 10 has a support portion to which the reflecting member 31 is attached at a position above the upper piece 11, 321, and a side piece that is in contact with the outer surface of the vertical piece 12. A portion 322, a horizontal piece portion 323 branched from the side piece portion 322 and abutting on the upper surface of the upper piece 11, and a claw portion 324 provided on the horizontal piece portion 323 and engaged with and supported by the end portion of the upper piece 11. It is equipped with.

The material of the connecting member 32 is made of resin and has a certain degree of flexibility. The inner corner portion composed of the horizontal piece portion 323 and the side piece portion 322 of the connecting member 32 is aligned with the corner portion of the chassis frame 10, and the claw portion 324 exceeds the end portion of the upper piece 11 of the chassis frame 10. By pushing it in, the claw portion 324 is engaged and supported by the end portion of the upper piece 11.

FIG. 3 is a perspective view of the side reflector according to the embodiment. As shown in this figure, the side piece portion 322, the horizontal piece portion 323, and the claw portion 324 have a constant width in the depth direction, and are engaged with and supported by the chassis frame 10 as shown in FIG. By doing so, the mounting position of the vehicle in the vehicle width direction is restricted.

Further, by adjusting the friction coefficient of the inner side surface of the connecting member 32, which is in contact with the chassis frame 10, the side piece portion 322, the horizontal piece portion 323, and the claw portion 324, or by changing the material or the cross-sectional shape, the vehicle front-rear direction It is also possible to adjust the slidability at.

The connecting member 32 is a resin member having the same cross section in the front-rear direction of the vehicle. Such members can be manufactured, for example, by extrusion molding.

FIG. 4 is a cross-sectional view showing an application example of the side reflector according to the embodiment. In this figure, only the configurations of the horizontal piece portion 323 and the claw portion 324 of the lateral reflector shown in FIGS. 2 and 3 are different, so only that portion will be described and the other parts will be omitted. This application example shows the connecting member 32 of the side reflector 30 which can cope with the case where the thickness and width of the chassis frame vary depending on the vehicle type.

The tip end side of the lateral piece portion 323 of the connecting member 32 includes an outer claw portion 328 and an inner claw portion 329 that are integrally continuous with the outer claw portion 328. These are claws corresponding to different thicknesses and widths. For example, when fixing to the chassis frame showing the contour by the virtual line VL1 by the alternate long and short dash line, only the inner claw portion 329 may be engaged with the end portion of the upper piece to engage the connecting member 32 with the chassis frame. can.

On the other hand, when fixing to the chassis frame showing the contour by the virtual line VL2 by the alternate long and short dash line, the inner claw portion 329 is not used and only the outer claw portion 328 is used. As described above, since the connecting member 32 is made of resin and has a certain degree of flexibility, the inner claw portion 329 is bent so as to rotate in the direction of the arrow and stored in the storage portion 326. can do.

The storage portion 326 is a groove or a recess provided on the side of the horizontal piece portion 323 in contact with the chassis frame, and has a cross section corresponding to the shape of the inner claw portion 329 as shown in the figure.

When the unused inner claw portion 329 is bent and stored as described above, it cannot be used again as a claw due to inplasticity depending on the resin of the material. However, after being transported to the erection manufacturer, the connecting member 32 is basically discarded, and a side reflector corresponding to the erection is installed, so that there is no problem. Therefore, the plurality of claw portions, which are the outer claw portion 328 and the inner claw portion 329, are selected and used according to the width and thickness of the chassis frame. Unused claws are folded and housed.

In order to make the inner claw portion 329 easy to bend, a groove portion 327 may be provided at the base portion where the inner claw portion 329 and the lateral piece portion 323 intersect. In this figure, the groove portion 327 is formed so as to extend in the vehicle traveling direction, and is a substantially circular groove having a lower left opening in a cross section.

In this way, by providing the plurality of claw portions and the storage portions having the corresponding shapes, the connecting member 32 and the chassis frame 10 are engaged and fixed corresponding to the chassis frames 10 having a plurality of thicknesses and widths. be able to.

The number of claws is not limited to two such as the outer claw portion 328 and the inner claw portion 329, and a larger number may be provided. For example, if there are five types of chassis frame thicknesses and widths that must be supported, five claws corresponding to the five types may be provided.
In the present embodiment, the mounting position of the reflective member 31 attached to the support portion 321 of the connecting member 31 is above the upper piece 11 of the chassis frame 10, that is, above the side piece portion 322 of the connecting member 32. Although it is located, the position is not limited to the upper side, and may be lateral or lower.

As described above, according to the embodiment of the present invention, reflection is performed by the support portion 321 of the connecting member 32 supported by the chassis frame 10, the side piece portion 322, the horizontal piece portion 323, and the claw portion 324. By fixing the position of the member 31, it is possible to mount the chassis frame 10 without providing a mounting hole, so that the man-hours required for mounting the side reflector 30 can be reduced.

Although the embodiments of the present invention have been described above, they can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
