Description

[Detailed description of the invention] [Industrial application field] This invention is applicable to sleeve cabinets placed on the floor below the top of desks, and movable storage furniture equipped with casters at the bottom of the main body. , relates to the structure of a device that prevents furniture from leaning forward and falling due to a drawer that is pulled out from the furniture body.

[Conventional technology and issues to be solved]

When a sleeve cabinet placed on the floor below a desk or a drawer in storage furniture that is movable on casters is pulled out from the furniture body, the center of gravity of the items stored in the drawer moves to the front of the furniture body. As a result, there is a risk that the furniture body may tilt forward and fall over, so prior art for preventing this is disclosed in Japanese Utility Model Publication No. 49-44831, Publication No. 40892-1982, Publication No. 102848-1984, etc. discloses that the lowermost drawer is provided with casters that roll in contact with the floor at the front of the lower surface of the drawer so as to be able to support the load of the front part of the drawer when it is pulled out.

Among them, the invention in Japanese Utility Model Application Publication No. 55-102848 is that the drawer is pushed into the furniture body and stored.
It is disclosed that the caster enters the front part of the furniture body and forms a notch recess into which the caster can fit into the front edge of the bottom plate of the furniture body so that the caster does not get in the way when the drawer is stored.

However, when pushing the drawer into the furniture body, the drawer can move to the left and right with respect to the furniture body, so the side of the caster, which is still in contact with the floor, collides with the side of the notch, causing the drawer to collapse. There was a problem that the pushing operation could not be carried out smoothly.

The present invention aims to solve this conventional problem.

[Means to solve the problem]

In order to achieve this purpose, the present invention is a storage furniture in which one or more drawers are disposed in the main body of the storage furniture such as a cabinet so that they can be moved back and forth. A support frame body provided with a grounding trochanter that can be grounded on a surface is protruded downward, and a guide is provided at the front part of the support frame body with a contact surface that narrows backward and slopes on both left and right sides in a plan view. A storage recess with an open front surface into which the support frame is inserted rearward is formed at the front of the lower end of the storage furniture main body, and a storage recess is formed in the vicinity of the front of both left and right sides of the storage recess. In the guide body, a guide surface is formed which is tapered at the rear in plan view and guides both the left and right abutment surfaces of the guide body.

[Functions and effects of the idea]

According to this configuration, a support frame body with a grounding trochanter that can be grounded to the floor surface is protruded downward from the front part of the bottom plate of the bottom drawer, so that when the drawer is pulled forward from the main body of the storage furniture, Since the front part of the drawn drawer is supported by the grounding trochanter, neither the storage furniture main body nor the drawer will tilt forward even though the center of gravity is moved forward by drawing the drawer far forward.

A front-open storage recess into which the support frame is inserted backwards is formed at the front of the lower end of the storage furniture body. When pushed in, the grounding trochanter on the lower surface and its support frame can also be accommodated in the storage recess.

Moreover, a guide body is protruded from the front part of the support frame body, and has abutment surfaces that narrow backward and tilt on both the left and right sides in a plan view, while a guide body is provided in the vicinity of the front part of both left and right sides of the storage recess. Since the guide surface is tapered in plan view to guide the left and right abutment surfaces of the guide body, as the support frame is pushed into the storage recess, the left and right abutment surfaces of the guide body and the storage furniture main body are formed. Since the bottom drawer can come into contact with the guide surface, even if the drawer is shifted to the left or right when pushing the bottom drawer, once the push-in operation is completed, the drawer will return to its left or right position within the main body of the storage furniture. It also has the effect of being able to be stored neatly without shifting.
