Description

Description: TECHNICAL FIELD The present invention relates to a wooden wagon suitably used in offices and the like.

[Related Art] Conventionally, as a wagon of this type, a steel wagon that is easy to be finely worked and hardly causes a dimensional error is widely used. However, steel products tend to give a short impression peculiar to a metal surface, and often give a cold feeling to the feet when they are arranged under a tabletop and used as sleeves.

For this reason, recently, wooden objects that are rich in visual changes from the viewpoint of emphasizing the appearance are being reviewed.

[Problems to be Solved by the Invention] However, wooden materials are difficult to be finely worked and easily deformed due to moisture or the like, so that there is a problem that it is difficult to obtain dimensional accuracy. Therefore, if the wagon is simply made of wood, there is a high possibility that the drawer may not be able to open and close smoothly due to dimensional errors, deformation, and the like, or that an unnecessary gap is formed between the upper and lower drawers. Also, if the fixed rail is directly fixed to the inner surface of the side plate via a wood screw, etc., the wood screw part may rattle due to the unique "thinness" of wood, and the load of the drawer can be supported for a long time. difficult.

An object of the present invention is to solve such a problem.

[Means for Solving the Problems] The present invention employs the following configuration in order to achieve such an object.

That is, the wagon according to the present invention is a wagon including left and right side plates, a top plate, a back plate, a structural frame for holding a drawer, and a base, and includes a left and right side plate, a top plate, and a back. Each of the face plates is made of wood, and the structural frame for holding the drawer is a metal frame including vertical members on the front side and the rear side, and a plurality of fixed rails rigidly connected perpendicularly to the vertical members. The vertical members on the front side and the rear side are fixed to the inner surface of the side plate, and the upper ends of the respective vertical members are aligned with the upper ends of the side plates. It is made of metal having an L-shaped receiving portion, and is characterized in that lower end portions of left and right side plates are connected to each other, and the receiving portion receives the inner surface and the bottom surface of the side plate.

When the locking mechanism is provided, the vertical member on the front side is preferably formed in a U-shape when viewed from the direction, and the lock claw driving rod of the locking mechanism is housed in a space inside thereof in a vertically movable manner.

In order to make the metal base inconspicuous, the tip of the receiving portion is preferably located inside the outer surface of the side plate.

If you want to make it easy to work inside the wagon and also to be able to handle various wagons with different depth dimensions, make the base independent of the front side connection member and the back side connection member Good.

In that case, it is preferable to provide a plurality of casters on the front side connecting member and the rear side connecting member, respectively, in terms of mobility and the like.

[Operation] With such a configuration, when rigidly connecting the vertical member and the fixed rail, the vertical dimension from the upper end of the vertical member to each fixed rail is adjusted from the lower surface of the top plate or the upper end of the side plate. It can correspond to the vertical dimension up to the drawer. For this reason,
When the upper ends of the vertical members are aligned with the upper ends of the side plates and each vertical member is fixed to the inner surface of the side plate, the positioning of each drawer in the vertical direction can be reliably performed. Moreover, since the vertical members and the fixed rails are made of metal, dimensional accuracy is easily obtained,
The accuracy can be maintained for a long time, and the dimensional control between the upper and lower drawers becomes easy. Further, the load of the drawer acting on the fixed rail is distributed to the vertical members on the front side and the rear side, and acts on the side plates via these vertical members. Furthermore, the drawer holding structural frame constituted by the vertical members and the fixed rails has a function as a rib of the side plate, and the structural frame can suppress deformation of the side plate. Furthermore, the lower ends of the left and right side plates are connected to each other by a metal base, and the inner and bottom surfaces of the side plates are received by the receiving portions of the base, so that the left and right side plates are not deformed in the width direction for a long time. At the same time, it is possible to reliably receive the load acting on the side plate.

Can be effectively increased.

Further, the distal ends 81k and 82k of the receiving portions 81c and 82c are
If it is located inside the outer side surface 1e of the vehicle, the metal base 8 is not noticeable, and the appearance of the wooden wagon can be effectively prevented from being impaired.

Also, if the base 8 is made independent of the front side connecting member 81 and the rear side connecting member 82, the front side and the bottom side are open, so that the work in the wagon can be smoothly performed from the front side and the bottom side. Can be done. In addition, such a configuration can be effectively applied to various wagons having different depth dimensions only by changing the mounting positions of the front-side connecting member 81 and the rear-side connecting member 82 back and forth.

In this case, if a plurality of casters 81d and 82d are provided on the front-side connecting member 81 and the rear-side connecting member 82, respectively, the movement of the wagon can be performed smoothly.

If gaps are provided between the vertical member 41 on the front side and the front connecting member 81 and between the vertical member 42 on the rear side and the rear connecting member 82, respectively, Even if a dimension error occurs, the error can be effectively absorbed in the gap. That is, in such a case, the lower end of the front-side vertical member 41 and the front-side connecting member 81 and the lower end of the rear-side vertical member 42 and the rear-side connecting member 82 due to an error in the vertical dimension of the side plate 1 Do not come into contact with each other, so that each of the equipment 41 and 42 and the connecting member 8
1, 82 can be securely fixed in a predetermined position, and there is no possibility that a mounting error occurs in a metal part due to expansion and contraction of a wooden part.

[Effects of the Invention] According to the present invention having the above-described configuration, a dimensional error hardly occurs between a plurality of drawers, and furthermore, deformation of a side plate can be effectively suppressed. As a result, it is possible to provide a wooden wagon which can smoothly open and close each drawer for a long period of time and which is excellent in appearance and usability. In particular, since the lower end portions of the left and right side plates are connected to each other by a metal base, and the inner surfaces and the bottom surface of the side plates are received by front-view L-shaped receiving portions formed on both the left and right sides of the base, The side plate can be prevented from being deformed in the width direction for a long time, and the load acting on the side plate can be reliably received by the base, so that the support strength against the load can be effectively increased.

Also, if a vertical member on the front side of the structural frame holding a plurality of drawers is formed in a U-shape in plan view and the locking claw operating rod of the locking mechanism is housed in the space inside so as to be able to move up and down, it can be used in a narrow space. The lock claw operating rod can be reliably operated, and when the drawer is opened during locking,
The operating force can be applied to the vertical members on the front side.
For this reason, the drawer can be reliably locked, and no excessive external force is applied to the locking mechanism.

Furthermore, when the tip of the receiving portion is located inside the outer side surface of the side plate, the metal base is not noticeable, and it is possible to effectively prevent the appearance of the wooden wagon from being impaired.

In addition, if the base is made independent of the front-side connecting member and the rear-side connecting member, the work inside the wagon can be performed smoothly from the front side and the bottom side. Moreover, such a configuration can be effectively applied to various wagons having different depth dimensions only by changing the mounting positions of the front-side connecting member and the rear-side connecting member back and forth.

When a plurality of casters are provided on the front-side connecting member and the rear-side connecting member, respectively, the movement of the wagon can be performed smoothly.
