Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing forward lean in a storage furniture such as a wagon with drawers, a sleeve desk, a side desk, and a side table.

[0002]

2. Description of the Related Art In a storage furniture such as a wagon, a sleeve desk, a side desk, and a side table provided with a drawer, a drawer closest to the floor (the bottom drawer in a case where a plurality of drawers are provided) is in front of the furniture body. When pulled out, the drawer may tilt forward due to the load of the stored items. In view of this, various storage furniture has been proposed in which the above-mentioned prevention casters are attached to the front end of the lower surface of the drawer closest to the floor.

For example, in a forward lean prevention structure described in Japanese Utility Model Publication No. 5-15220, a support frame for supporting a trochanter is screwed to a mounting bracket attached to a front portion of a bottom plate of a drawer. The positioning and fixing is performed by fitting the tongue piece bent and formed into the hole formed in the lower bent portion of the front plate. However, in such a configuration, since the support frame is fixed to the mounting plate using screws, a tool is required for mounting, and the mounting work is troublesome. In particular, in the case of storage furniture with casters on the bottom of the furniture body, these casters are often attached to the furniture body at the time of shipment from the delivery base or at the delivery destination, in which case the front front end of the drawer is prevented from tilting forward If the casters are mounted in advance, the forward lean prevention casters protrude downward, which hinders storage and packing. Therefore, it is desirable to mount the forward lean prevention caster immediately before delivery at the delivery base or at the delivery destination, but the work cannot be efficiently performed by screw mounting. Further, since the tongue piece for positioning is made by punching and bending a metal support frame, the tongue piece is easily affected by variations in the punching and bending accuracy of the support frame. In addition, when the front plate having the holes is made of steel, the accuracy of the positioning of the forward tilt preventing casters is greatly reduced because the accuracy of the hole machining accuracy is also affected.

Further, the caster mounting structure for preventing the furniture from leaning forward described in Japanese Utility Model Laid-Open No. 5-84238 has a front plate made of a synthetic resin and a front plate back cover spot-welded to a bottom plate. A trochanter made of synthetic resin supporting the trochanter is fitted into the front plate of the drawer and positioned up, down, left and right, and the trochanter support is formed by the front edges of the front plate and the bottom plate and the front plate back cover. It is configured to be positioned and fixed in the front-rear direction by being sandwiched between the lower bent edge and the front and rear. However, in this forward-tilt preventing caster mounting structure, since it is necessary to screw the front plate and the bottom plate after attaching the trochanter support to the front plate, it takes time to attach the forward-tilt preventing casters. Therefore, also in this mounting structure, it is not possible to efficiently mount the forward tilt preventing caster immediately before delivery at the delivery base or at the delivery destination. In addition, since the front-rear positioning means of the trochanter support uses the front edge of the bottom plate, usually made of a metal plate, and the lower edge bent edge of the back cover of the front plate, the influence of variations in the bending accuracy of the back plate is reduced. And the positioning accuracy of the forward lean preventing casters in the front-rear direction is greatly reduced.

On the other hand, a mounting structure of a caster for preventing forward leaning that does not require screwing is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 7-25547 and 7-255548. In this mounting structure, the front plate of the drawer is composed of a front plate and a back plate, and a trochanter support made of synthetic resin holding the trochanter is fitted into the front plate of the drawer and is fixed vertically, horizontally, and vertically. The casters can be attached by one-touch operation.However, the means for preventing falling down uses a hole formed in the back plate, which is usually made of a metal plate. It is susceptible to variations in plate processing accuracy, which causes a significant decrease in the vertical positioning accuracy of the forward tilt preventing casters.

On the other hand, if the trochanter made of synthetic resin, which supports the trochanter, is positioned and fixed using only the front plate made of synthetic resin, the positioning accuracy can be improved. In addition, the strength of the trochanter support is reduced, and the trochanter may fall off or be damaged by an impact when the trochanter comes into contact with a step or a protrusion on the floor.

[0007]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to prevent forward leaning in a storage furniture which can be easily attached to a drawer and which can ensure high attachment strength and positioning accuracy. Is to provide.

[0008]

The present invention provides a structure for preventing leaning forward in storage furniture, characterized in that a support portion is provided in the storage furniture.

According to the above structure, the trochanter support made of synthetic resin for supporting the trochanter is fitted into the mounting portion of the front plate of the drawer from below, and is fixed so as to be positionable in the front-rear, left-right and up-down directions. In addition, the trochanter support can be easily attached to the drawer without any tools or the like. Therefore, the trochanter support made of synthetic resin for supporting the trochanter can be separated from the drawer until immediately before the storage furniture is delivered from the delivery base or immediately before assembly starts at the delivery destination. It is possible to reduce the size of the storage at the delivery base and the packing and the like at the time of delivery from the manufacturing base to the delivery base or to the delivery destination, so that the cost can be reduced. Further, since the trochanter support is positioned up and down, right and left, and up and down by the trochanter support made of synthetic resin and the front plate made of synthetic resin, high positioning accuracy can be secured. Furthermore, the metal front plate back cover is provided with a support portion that supports the upwardly protruding portion provided on the trochanter support in the front, rear, left and right, so that when the drawer is pulled out, the trochanter is on the floor. When an impact is applied to the trochanter by colliding with a protruding object or a step on the surface, the trochanter support may be supported by the supporting portion provided on the metal front plate back cover against the impact. So you can
It is possible to prevent the trochanter support from falling off due to the impact and to prevent the trochanter support or the front plate from being damaged. Further, since it is not necessary to ensure the positioning accuracy with respect to the trochanter support in the support portion of the front plate back cover, it is not necessary to ensure high processing accuracy, and therefore, it is possible to manufacture at low cost.

[0010] In the above structure, preferably, the support portion has a lower end bent edge formed by bending forward from a lower end of the front plate back cover, and the lower end bent edge has the trochanter support. A through hole is formed that fits with the protrusion of the trochanter support when the body is positioned at the mounting portion of the front plate. According to this configuration, the lower end of the front plate back cover is bent forward to form a lower bent edge, so that the rigidity of the front plate back cover can be increased. A through-hole is formed at the bent edge of the lower end of the front plate back cover so as to fit with the protrusion of the trochanter support with clearance, so that when an impact is applied to the trochanter, the trochanter rolls against this impact. A support portion that can safely support the child support can be realized with a simple configuration.

Preferably, the support portion has a support fitting attached to a front side of the back cover of the front plate, and the trochanter support is positioned on the attachment portion of the front plate at the support fitting. At this time, two through-holes are formed at two places vertically spaced from each other so as to fit with the protruding portions of the trochanter support. According to such a configuration, when the trochanter support is positioned at the mounting portion of the front plate, the two transparent members formed at an interval above and below the support bracket attached to the metal front plate back cover. Since the hole fits with the protrusion of the trochanter support with a clearance, when the trochanter is subjected to an impact, the trochanter support is supported at two points up and down by supporting metal against the impact. Can be. Therefore, it is possible to realize a supporting portion having a higher supporting strength.

Preferably, a mounting portion of the front plate receives the trochanter support from below and holds the trochanter support in a positionable manner in the front, rear, left and right directions, and the mounting portion fitted into the holding portion. A stopper portion for restricting upward movement of the trochanter support, wherein the trochanter support fitted into the holding portion is moved upward by the mounting portion of the front plate and the trochanter support; Elastic stopper means for restricting downward movement of the trochanter support using elasticity at a position where the trochanter is restricted.
According to such a configuration, it is possible to realize a protruding portion for positioning and fixing the trochanter support in the front-rear, left-right, and up-down directions with a simple configuration.

More preferably, the front plate has a horizontal wall portion overlapping the lower surface of the lower bent edge of the front plate back cover, and the lower surface of the horizontal wall portion constitutes the stopper portion of the mounting portion. According to this configuration, the load of the object accommodated in the drawer acts directly on the trochanter support from the bent edge of the lower end of the metal front plate back cover via the horizontal wall portion of the front plate, and is therefore accommodated in the drawer. It is possible to prevent bending or bending stress from being applied to the front plate made of synthetic resin due to the load of the stored contents. Therefore, it is possible to provide a forward lean prevention structure in the storage furniture that can support the trochanter support while preventing the strength of the front plate from decreasing.
