BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary fixing device for transporting furniture provided with a shelf board such as a cabinet so that the shelf board does not move in the furniture body.

[0002]

2. Description of the Related Art In general, a temporary fixing device of this type is engaged with a large number of engaging grooves formed in the inner surface of a furniture main body at appropriate intervals above and below in order to lock a supporting member to a shelf board. By contacting the upper surface of the shelf in this state, the shelf is held immovable upward. As an example, Japanese Utility Model Publication No. 51-31138 discloses a temporary fixing device formed in a substantially C shape by a leaf spring, and the upper end thereof is fitted into a locking groove of a furniture body from below. An upper U-shaped upper locking portion that is to be engaged is bent and formed, while a lower locking fits into a gap between an inner surface of the furniture body and an outer surface of the shelf plate from above at a lower end thereof. There is described a device in which a portion is bent and a temporary fixing device is elastically deformed so as to be stretched in a vertical direction so as to urge the shelf board downward.

[0003]

However, in this prior art, since the shelf board is pressed and urged downward by the elastic force of the temporary fixing tool, if the shelf board can be simply fixed in the furniture body. It has the advantage that it can prevent rattling of the shelf during transportation, but on the other hand, the temporary fastening tool is stretched up and down by its elastic force,
In addition, since the upper locking part holds the state engaged with the locking groove of the furniture main body, if the shelf plate vibrates up and down during transportation such as truck transportation, the temporary fixing tool will be elastically irregular. There is a risk that a temporary dance will fall off the furniture body due to a deformed dance phenomenon.

[0004] That is, the lower locking portion of the temporary fixing member is merely inserted from above into the gap between the inner surface of the furniture main body and the outer surface of the shelf board. When a pressing force that narrows the interval between the upper and lower ends of the stopper acts intermittently, and the temporary stopper has a dancing phenomenon,
There is a risk that the lower engaging portion may fall out of the gap between the inner side surface of the furniture main body and the outer side surface of the shelf board, and the temporary fastener may fall off the furniture main body.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a temporary fixing device capable of reliably preventing the shelves from dropping off from the furniture main body under the condition in which the shelves are prevented from rattling during transportation. .

[0006]

In order to achieve this object, the present invention provides an elastic material made of an elastic material in which a shelf with both left and right edges folded in a U-shape is fixed inside a furniture body in an inverted state. A temporary fixing device, wherein the temporary fixing device is fitted and engaged with a locking groove formed in an inner side surface of the furniture main body in a state of being in contact with an upper surface of a folded portion of the shelf board. A lower locking claw, an upper locking claw adapted to fit into and engage with a locking groove formed above the locking groove in which the lower locking claw is engaged. With a connecting part to connect the pawl,
At the lower end or lower locking claw of the connecting portion, a downward projection is formed to engage with the leading edge of the folded portion on the shelf, and an appropriate portion of the connecting portion is engaged with the locking groove. The upper and lower locking claws are formed in a spring portion which is urged in a direction in which the upper and lower locking claws are separated from each other.

[0007]

In this configuration, for example, two shelves are placed on the main plate of the cabinet body in a state where the two shelves are overlapped with the upper shelves turned upside down, and the temporary fixing tool is placed on the main plate. The upper and lower locking claws are deformed against elasticity so as to reduce the vertical distance between the tips, and then the upper and lower locking claws are respectively locked in the locking slots on the left and right inner side surfaces of the furniture body. By attaching to the left and right inner surfaces of the furniture body at the location of the top of the folded part on the shelf,
The shelf board can be fixed in the furniture main body, and the temporary fixing device is deformed by the reverse operation, and the upper and lower locking claws are pulled out from the locking groove, thereby removing the temporary fixing device from the furniture main body. be able to.

When the temporary fixing device is mounted on the furniture main body, the upper and lower locking claws are engaged with the locking grooves, respectively. Even if the upward pressing force is applied intermittently, the upper and lower locking claws do not fall out of the locking slots, and therefore, it is ensured that the temporary fasteners come out of the furniture body due to the vibration of the shelf during transportation. Can be prevented.

When the temporary fixing device is attached to the inner surface of the furniture main body, the upper surface of the folded portion of the shelf is elastically pressed by the elastic force of the spring portion, so that the shelf moves upward. Further, the downward projections of the temporary fasteners respectively attached to the left and right inner surfaces of the furniture main body are engaged with the tips of the folded portions on the left and right side edges of the shelf, respectively. The shelf is also held immovable in the left-right direction, and as a result, the shelf board is held immovable.

[0010] Therefore, according to the present invention, although the temporary fixing device can surely prevent rattling of the shelf plate during the transportation of furniture, it is possible to reliably prevent the temporary fixing device from dropping due to vibration during transportation. It has the effect of being prevented.
