Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shelf support device for supporting a shelf between both side walls of a cargo compartment of a freight vehicle.

(Prior art and its problems) As shown in Figures 1 and 2, a truck 1
For example, when loading products 3 packed in cardboard cases into the cargo compartment 2 of The cargo compartment 2 is divided into a plurality of upper and lower stages by constructing shelf boards 5 of one or more stages.

Both ends of the shelf board 5 are placed on shelf supports having a substantially L-shaped cross section that are detachably attached to the side walls 4 of the cargo compartment, and are removed together with the shelf supports when unnecessary. Conventionally, however, locking holes are provided at appropriate intervals in the lengthwise direction of the shelf support, or locking hooks are attached to the back surface of the shelf support, and rivets or locking hooks are fixed to the side walls of the cargo compartment. The shelf support is attached to both side walls of the cargo compartment by engaging the member with the cylindrical locking hole or the locking hook.

In such a conventional configuration, the cargo load on the shelf is concentrated at the engagement point between the rivet or locked member on both side walls of the cargo compartment and the daruma-shaped locking hole or locking hook on the shelf receiving side. As a result, the attached parts such as the rivets, locked members, and locking hooks are likely to be damaged or fall off, resulting in poor durability. If it is not possible to standardize the rivet spacing or the spacing between the locked parts, it is necessary to prepare multiple types of shelf supports with different daruma-shaped locking hole spacing or locking hook spacing. There was the inconvenience of having to select the specified installation position and erect each shelf support.

(Means for solving the problems) The present invention proposes a truck shelf support device that can solve the conventional problems as described above. A band-shaped shelf holder locking member having an upper side for hooking the shelf holder is attached to both side walls of the cargo compartment so as not to protrude inward from the inner surface of the side wall, and the removable shelf holder is attached to the shelf holder locking member. It has a substantially L-shaped cross section, including a rising wall portion along the inside of the stopper member, and a shelf receiving portion protruding at a right angle from the lower side of the rising wall portion, and the shelf receiving portion is provided on the rising wall portion. A hook part that can be fitted from above to the upper side part for hooking, and a protrusion part that fits into the lower side of the lower side continuous in the length direction of the lower part of the shelf receiver locking member in the length direction. It is a point that has been made continuous.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIG. 3, numeral 10 is a band-shaped shelf holder locking member formed by extrusion molding of aluminum, and numeral 11 is a shelf holder having a substantially L-shaped cross section also formed by extrusion molding of aluminum.

The shelf holder locking member 10 is formed with an upper side portion 12 for hooking the shelf holder that is continuous in the length direction, and a recessed groove 13 is formed on the lower side of the upper side portion 12 and on the surface side. This recessed groove 13 forms a lower side portion 14 that protrudes inward and is continuous in the length direction. In the recessed groove 13,
Attachment holes 15 are provided at both lengthwise ends or at appropriate intervals.

The shelf support 11 includes a rising wall portion 16 along the inside of the shelf support locking member 10, and a shelf support portion 17 protruding approximately perpendicularly from the lower side of the rising wall portion 16. These include a hook portion 18 that can be fitted from above to the upper side portion 12 for hooking a shelf holder of the shelf holder locking member 10, and a protrusion that fits into the lower side of the lower surface 14a of the shelf holder locking member 10. 19 are formed continuously in the length direction. In the illustrated example, a separate protrusion 20 is formed continuously in the length direction on the upper side of the protrusion 19, and the lower side 14 of the shelf receiver locking member 10 is sandwiched between these protrusions 19 and 20. However, the protrusion 20 is not essential to the present invention and can be omitted.

The shelf support locking member 10 is attached to the shelf board support height of the cargo compartment side walls 4 shown in FIG.
The details will be explained based on FIG. 4. In this type of truck, the cargo compartment side wall 4 is the outer wall 2.
1. Inner wall 22, heat insulating layer 23 between both walls, and inner wall 2
The air rib 24 is cut out at a width that is appropriately wider than the width of the shelf support locking member 10 at the shelf support height, and the air rib is removed. The shelf support locking member 10 is attached to the inner wall 22 at a location 25.
is fixed using the mounting hole 15 and the screw 26 passing through it. At this time, the shelf receiver locking member 10 is configured so as not to protrude further into the cargo compartment than the surface of the air rib 24.

Although various methods of fixing the shelf holder locking member 10 can be considered, in the illustrated example, the base plate 29 to which the cover plate 28 that forms the protruding space 27 of the screw 26 is fixed is placed at the shelf holder locking member mounting height. The screws 26 are fixed in advance to the back side of the inner wall 22 by an appropriate method such as screwing or welding, and the screws 26 are inserted through the inner wall 22.
is configured to be screwed through the substrate 29. The cover plate 28 and the substrate 29
may be provided only at locations corresponding to the screws 26, or may be provided over the entire length of the attachment area of the shelf receiver locking member 10. Further, the shelf receiver locking member 10 is attached over the entire length of the cargo compartment side walls 4, but the shelf receiver locking member 10 itself can be divided into a plurality of parts.

When constructing the shelf board 5, the hook part 18 of the shelf holder 11 is hooked from above to the upper side 12 of the shelf holder locking member 10, and then the wall 16 stands up and approaches the shelf holder locking member 10. Rotate it so that
With this, the protrusion 19 is attached to the lower surface 1 of the shelf receiver locking member 10.
Insert it under 4a. As a result, the shelf holder 11 is locked to the shelf holder locking member 10 such that the shelf holder 17 is perpendicular to the side wall 4 of the cargo compartment. Of course, the shelf support 11 is attached over the entire length of both side walls 4 of the cargo compartment, but the shelf support 11 itself can be divided into a plurality of parts so that it can be easily attached and removed. At this time, the length of each shelf support 11 may not be constant.

As described above, the shelf supports 11 are attached to the cargo compartment side walls 4.
Once installed, a large number of shelf boards 5, which are slightly shorter than the width between both side walls 4 and divided in the length direction of the shelf supports 11, are sequentially placed on the shelf supports 17 of both shelf supports 11. , a predetermined number of intermediate shelves can be constructed. If the intermediate shelf is not required, the shelf board 5 and shelf support 11 can be removed by following the procedure reverse to the above.

(Operations and Effects of the Invention) The shelf support device for a freight vehicle of the present invention can be implemented as described above. When the shelf holder is locked to the locking member, the hook part that is continuous over the entire length of the shelf holder is fitted into the upper side part that is continuous over the entire length of the shelf holder locking member. The applied load can be transmitted to the shelf holder locking member by distributing it over its entire length, eliminating the risk of locally concentrated loads acting as in the conventional case, and reducing the need for both the shelf holder locking member and the shelf holder. Coupled with the fact that it can be made extremely durable by extrusion molding of aluminum or the like, it can be safely used as a support device with extremely excellent durability.

Furthermore, both the shelf support locking members attached to both side walls of the cargo compartment and the shelf supports removably engaged therewith are divided into arbitrary numbers in the length direction of the cargo compartment side walls. In addition, there is no need to keep the individual lengths the same, and even when using the shelf supports, the location of each shelf support is not specified, so it is easy to use in cargo compartments with side doors. The present invention can be applied to a variety of applications, and the installation work of shelf supports can be performed easily and efficiently.
