Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a moving type wagon used in an office or the like.

[Prior Art] Conventionally, in this type of wagon, the side surface of the base is located flush with the side surface of the wagon body or inside the side surface of the wagon body.

[Problems to be solved by the invention] However, with such a configuration, when the wagon is stored under the top plate cantilevered on the wall surface, or when the wagon is pulled out from under the top plate, or When the side surface of the wagon body collides with a wall surface or a corner portion of the floor when moving on the floor, etc., the side surface or wall surface of the wagon is damaged, resulting in a problem that the appearance is deteriorated. In particular, since the wagon equipped with casters can freely move back and forth and right and left, such a problem is relatively likely to occur.

The present invention aims to eliminate such a problem.

[Means for Solving the Problems] The present invention adopts the following configurations in order to achieve the above-mentioned objects.

That is, the wagon according to the present invention comprises a base including a metal base body having casters and a bumper member fixed to the outer periphery of the base body, and the wagon body, the bumper member having the outer periphery. Is provided with a recessed groove in the center thereof, and a stopper is disposed in the recessed groove so as to be fixed in a state of being positioned outside the side surface of the wagon body.

In order to firmly fix the bumper member to the outer periphery of the base body and to effectively absorb the impact at the time of collision, the bumper member is made of a hard synthetic resin base and a soft synthetic resin covering the outside of the base. It is preferable that the base body is fixed to the outer periphery of the base body by forming an outer package.

In order to easily attach the bumper member to the outer periphery of the base body and to avoid the presence of a seam on the surface of the bumper member, the portion corresponding to the corner of the base body is cut out in a V shape from the inner surface side. The bumper member is preferably fixed to the outer periphery of the base body.

[Operation] With such a configuration, even if the wagon collides with a wall surface or a corner when the wagon is moved, the bumper member of the base is located outside the wagon body. Therefore, the side surface of the wagon body is prevented from colliding with the wall surface, the corner, etc. first by contacting the wall surface, the corner, etc. Moreover, since this bumper member is fixed to the outer circumference of the metal base body by disposing the fastener in the groove formed in the outer circumference of the base body, even in the event of a collision as described above, The fastening tool that fastens the bumper member does not come off due to the wall surface, corners, etc. Therefore, the bumper member itself does not drop from the base body.

Further, if the outer side of the bumper member is made of a flexible and rigid resinous outer body, the bumper member absorbs the impact at the time of collision and protects the wagon and the wall surface from being damaged.

Expands inside the side frame member 11, the front frame member 14, and the rear frame member 15, and this bumper member 1B can be attached to the outer periphery of the base body 1A. As shown in FIG. 6, a V-shaped cutout area 1D is formed in a portion corresponding to the corner 1c of the base body 1A. The cut region 1D is formed by cutting the bumper member 1B at 90 ° from the inner surface side, bends both sides thereof at 90 ° and abuts on the outer periphery of the base body 1A, and the vicinity of the corner 1c is as described above. It is fastened with a clip 19.

With such a configuration, when the wagon is moved, for example, as shown in FIG. 8, under the top plate b which is cantilevered on the wall surface a via a bracket (not shown), etc. Even when the wagon is housed in the vehicle and the wagon is placed along the side wall c or the wagon housed under the top plate b is pulled out, the bumper member 1
B contacts the wall surface c and prevents further movement. Therefore, it is possible to prevent the side surface 3a of the wagon body 3 and the wall surface c from colliding with each other or rubbing against each other, and it is possible to effectively prevent the defect that the side surface 3b and the wall surface c are damaged. . Even when the wagon is moved on a floor, a corridor, or the like, it is possible to similarly avoid the problem that the side surface 3a collides with a corner or the like and is damaged.

Moreover, since the base body 1A is made of metal and the bumper member 1B is fixed to the outer periphery of the base body 1A, a buffering function can be easily provided to the base 1 without lowering the rigidity of the base 1. Can be granted. Moreover, with such a structure, the base body 1A can be manufactured in the conventional manner, and the separately manufactured bumper member 1B can be retrofitted to the base body 1A, resulting in troublesome manufacturing work. Will not be invited.

Further, the bumper member 1B is attached to the base 1 made of a hard synthetic resin.
7 and the outer body 18 made of a soft synthetic resin that covers the outside of the base body 17, and the base body 17 is fixed to the base body 1B. Therefore, the bumper member 1B is firmly fixed to the base body 1A. It is possible to effectively absorb the impact at the time of collision.

In addition, a portion corresponding to the corner 1c of the base body 1A is cut into a V shape from the inner surface side, and the portion is bent to form the base body 1
Since the bumper member 1B is fixed to the outer periphery of A, an integrated bumper member 1B can be used. Therefore, the bumper member 1B can be easily attached to the outer periphery of the base body 1A, and it is possible to avoid the presence of a seam on the surface of the bumper member 1B, and the mounting work of the bumper member 1B can be performed quickly. , The appearance can be improved.

The bumper member 1B may be fixed to the outer circumference of the base body 1A by using bolts or the like, but the clip 19 can be used to easily attach and detach the bumper member as described above. .

[Advantage of the Invention] The present invention comprises a base having a metal base body and a bumper member fixed to the outer periphery of the base body, and has a groove formed on the outer periphery of the bumper member. Since the bumper member is fixed to the base body by arranging the fastener, the cushioning function can be easily added to the base without lowering the rigidity of the base, which complicates the manufacturing process. The bumper member can be securely attached without causing a problem such as a problem. In addition, since the fastener is arranged in the groove, even if the base collides with the wall surface or the corner of the floor prior to the collision of the wagon body when moving the wagon, It is possible to reliably prevent the bumper member from falling off without applying excessive force such as impact force directly.

Further, if the bumper member is composed of a base body made of a hard synthetic resin and an exterior body made of a soft synthetic resin covering the outside of the base body, and the base body is fixed to the base body, the bumper member is formed. It can be firmly fixed to the base body and can effectively absorb the impact at the time of a collision.

In addition, when a portion corresponding to a corner of the base body is cut out from the inner surface side in a V shape and the portion is bent and the bumper member is fixed to the outer periphery of the base body, the bumper member is an integrated product. Can be used. Therefore, the bumper member can be easily attached to the outer periphery of the base body, and the work of mounting the bumper member can be performed quickly. Moreover, by doing so, it is possible to effectively avoid the presence of a seam on the surface of the corner portion of the bumper member, and improve the appearance.
