Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a hard case that can be detachably mounted on a roof of a passenger car, a wagon car or the like for outdoor leisure.

[0002]

[Prior art]

 In the past, when enjoying outdoor leisure activities such as camping and surfing, in addition to packing these in the trunk or seat of passenger cars and wagons to carry those essential items, recently, a box-shaped load carrier has been installed on the roof of the car. The method of mounting a special case of the has come to be widely adopted.

[0003]

[Problems to be solved by the device]

 When using the above box-shaped special case, the special case was fixedly attached to the road carrier on the vehicle. It had to be carried out at a high position, and a great burden was seen in terms of time and physical strength.

In addition, it takes a lot of time to carry leisure goods taken out from the above-mentioned special case from a parking position to a destination such as a local place or an indoor place, and in the case of a condominium residence, etc. There was also the problem of making space difficult.

[0005]

[Means for Solving the Problems]

 According to the present invention, a light metal pull-out rail is attached to two rail grooves which are recessed in the front-rear direction on the rear surface of the bottom lid of a box-shaped case made of hard plastic, and each rail is penetrated at least at two positions. A pair of left and right clamps that clamp the rod of the load carrier through the long holes can be fixed with a single bolt, and large wheels can be rotatably pivoted on both sides of the rear end of the case bottom cover. I used the means of wearing.

Further, in the present invention, instead of the means for fixing the load carrier to the rod portion by the holding tool, a means of band fixing the fixing of the special case to the rod portion of the load carrier is also used.

[0007]

[Action]

 Since the exclusive case of the present invention is made entirely of plastic except for light metal used for parts such as rails, the entire case is made lighter and the wheels are provided at the rear end to transport the special box.・ Easy to move, etc., and its large wheels have the effect that labor can be raised and lowered on uneven roads and stairs.

[0008] Furthermore, the structure in which the rod portion of the load carrier is bolted by the holding tool attached to the bottom surface of the bottom of the special case is provided with one bolt for each holding tool fixed in four places. By loosening (4 pieces in total), the special box can be easily attached and detached, which is a very excellent effect.

Further, the case where the special case is fixed to the load carrier by the band can also be easily detached.

[0010]

【Example】

 Hereinafter, the structure of a special case according to the present invention will be described in more detail in accordance with an embodiment shown in the drawings. FIG. 1 shows an example of a passenger car equipped with a general load carrier (R) on a roof. Reference numeral 1 is a leg of the load carrier, and 2 is a rod that is inserted and fixed between the legs 1 and 1 on both sides.

2 and 3, 3 is a box-shaped special case that is composed of an upper lid 3a, a bottom lid 3b, and a handle 3c and is openable and closable, and 4 is a concave portion provided in the front-rear direction of the bottom lid 3b of the special case 3. The rail groove 5 or 5 is a rail obtained by pultrusion of a light alloy such as aluminum attached in the rail groove 4 and has two elongated holes 5a at the front and rear positions of each rail. It is provided so as to penetrate the lid 3b. Reference numeral 6 denotes a relatively large wheel rotatably attached to both side surfaces of the rear end portion of the bottom lid 3b in the longitudinal direction (forward and rearward direction).

Further, 7 in FIGS. 4 and 5 is a holding tool which is fixed to the bottom cover 3b of the special case with a screw 8a through the long hole 5a of the rail 5, and is molded from plastic such as nylon or polyester. , Which are composed of angle-shaped members 7a and 7b facing each other, and at the same time the inner screw members 7c and 7d are inserted into the vertical and horizontal portions of one member 7a, respectively, and at the same time the vertical and horizontal portions of the other member 7b are inserted. The through holes 7e and 7f communicating with the inner screw members 7c and 7d are provided therethrough.

By the way, when attaching the special case to the load carrier, the holding tool 7 is previously combined with the bottom lid back surface of the special case, and the screw 8a is inserted into the through hole 7f communicating with the inner screw member 7d. It is fixed by the nut 8b through the long hole 5a of the rail 5. Next, the rods 2 of the load carrier are fitted to the clamps 7 of each set fixed to the side of the exclusive case 3 in this way, and the inner screws embedded in the vertical portions of the angle-shaped members respectively. The bolt 9 is inserted through the material 7e to pinch the rod.

The standard dimensions of the box-shaped special case 3 in the present invention are as follows: the width is 800 mm, the length is 1020 mm, the front height is 160 mm, and the rear height is 200 mm. It is formed so as to be avoided, and is usually vacuum-molded by a light-weight hard plastic material such as polycarbonate, but in the present invention, the above-mentioned materials and the molding method are not particularly limited.

In addition, in the present invention, a reinforcing band 3d (see FIGS. 1 and 2) such as an aluminum plate is attached to at least the peripheral portions of the top lid 3a and the bottom lid 3b, and an appropriate gap is formed when molding the top lid and the bottom lid. By keeping the reinforcement ribs raised, the entire dedicated case has a thin structure, and the weight has been reduced sufficiently.

Further, as another embodiment of the present invention, the exclusive case 3 is fastened to the rod portion 2 of the direct load carrier (R) by using a hand (not shown) without using the holding tool 7. In this case, the holding tool 7 may be removed from the rail side, or the rail groove 4 and the rail 5 of the bottom lid 3b may be omitted.

[0017]

[Effect of device]

 As is clear from the above detailed description, according to the special case according to the present invention, attachment / detachment to / from the load carrier on the vehicle can be easily performed by operating four bolts, and the special case that has been lowered can be used as it is. Not only flat paved roads can be handled by the handles and wheels, but it is also possible to easily drive on roads with many irregularities and steps such as ground roads and stairs.

Further, as described above, according to the present invention, the special case can be easily removed from the load carrier by a holding tool, a hand, etc., and the tools can be taken in and out. It is possible to obtain remarkable labor-saving effects in the transportation of relatively lightweight and bulky equipment, such as tents, sleeping bags, mats, and other small props that are regularly used in the field, or in the indoors after returning. is there.
