Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a table device called an extension table.

A plurality of table pieces are housed in a stacked state in a device body such as furniture, and when one table piece is pulled out during use, the other table pieces are pulled out in succession and can be configured as a single table plate. , there is a tendency for table devices called so-called extension tables to be used frequently. These table pieces can be taken in and out through an opening in the main body of the device, and a curtain plate is provided at an upper portion along this opening. Then, when you pull out the table piece from the main body of the device,
The table piece placed on top moves together with the table piece below and comes into contact with the curtain plate, regulating the drawer.
The table pieces are pulled out in order starting from the bottom and are configured as a single table board. Furthermore, when the table piece is pushed into the apparatus main body again from this state, the rear table piece must be lifted upward in order to insert the front table piece below, and it tends to jump up inside the apparatus main body.

If you insert or remove a table piece with even a slight strong force like this, the table piece will collide with the curtain plate, top plate, or back plate, causing damage to the lower surface of the top plate, the back plate, and the inner surface of the curtain plate. Furthermore, damage such as the curtain plate falling off from the main body of the apparatus is likely to occur, and conventionally, no means has been provided to reliably prevent this.

The present invention was made with attention to the above circumstances, and its purpose is to improve the curtain plate and back plate between the top plate of the device main body and the support mechanism that supports the table piece installed inside the device main body. It is an object of the present invention to provide a table device that can reliably prevent damage to the top plate and the curtain plate by installing a crosspiece-like damage prevention body between the table pieces and buffering the shock when the table piece is taken in and out. That is.

An embodiment of the present invention will be described below based on the drawings. In the figure, reference numeral 1 denotes a main body of the device such as furniture, and the main body 1 of the device is provided with a table piece storage chamber 2 having an opening 2a in the upper front surface, and a storage space in which a door body 3 is pivotally mounted in the lower part so as to be openable and closable. A room 4 is provided.
The table piece storage chamber 2 includes a curtain plate 5, a top plate 6,
It is composed of a back plate 7, an internal bottom plate 8, and reinforcing bars 9, 9, which are bar-shaped damage prevention bodies. The reinforcing beams 9, 9 are fixed at one end to the curtain plate 5 and at the other end to the back plate 7, and are constructed between them. It goes without saying that strong strength can be obtained by bringing the upper ends of the reinforcing bars 9, 9 into close contact with the lower surface of the top plate 6.

The table piece storage chamber 2 accommodates first and second table pieces 12 and 13 supported by the support mechanism 11 so as to be freely removable and removable. This support mechanism 11 is
Its basic structure is extendable slide rails 14, 14 provided along both sides of the table piece storage chamber 2. Each of the slide rails 14, 14 has a portion with the largest diameter fixed to the table piece storage chamber 2, and a portion with a gradually smaller diameter, for example, the remaining 3 portions.
The steps can be protruded freely. This slide rail 14,
A hand-holding front plate 12a of the first table piece 12 is fixed to the end of the smallest diameter portion of the table piece 14, and the slide rails 14, 14 can be expanded and contracted by moving this hand-holding front plate 12a in the front and back direction. It is something. Also, at the rear end of the first table piece 12, there is a striker 1 formed by bending a round bar outward.
5 and 15 are attached, grooves 16 and 16 are provided on the front end side of the second table piece 13, and rollers 17 and 17 that run on the slide rails 14 and 14 are attached to the rear end. has been done. This second table piece 13 rests on the slide rails 14, 14 with the slide rails 14, 14 pulled out, and when all of them are pushed into the table piece storage chamber 2, the second table piece 13 is placed on the first table piece as will be described later. It's starting to appear on top of the 12th. Note that the first and second table pieces 1
2 and 13 are connected by a connecting rod 18 provided along the front-rear direction at approximately the center of each other.
Further, lift guides 19, 19 having an inclined surface are integrally provided on the upper surfaces of the rear ends of the largest diameter parts of the slide rails 14, 14, and guide tools 20, 20 are attached to the side surfaces of the front ends thereof. There is. The guide tools 20, 20 each have an L-shape, and their bent portions are pivotably attached to the side surfaces of the slide rails 14, 14, respectively. Also, guide tools 20, 2
Guide rollers 21, 21 are rotatably supported at one end of the table 0, and a torsion spring 21a is attached so that the guide rollers 21, 21 always come into elastic contact with the first and second table pieces 12, 13. , 21a. The torsion springs 21a, 21a have such strength that the guide tools 20, 20 are rotated by the weight of the first and second table pieces 12, 13. Further, the guide rollers 21, 21 are
It is located at a position where it is inserted into the concave grooves 16, 16 of the table piece 13. Further, the strikers 15, 15 contact the other ends of the guide tools 20, 20 as they travel, but when the guide rollers 21, 21 move into the grooves 16, 16, the guide tools 20, 20,
Since the rotation angle of 20 is large, striker 15,
15 never come into contact with each other.

As shown in FIG. 2, when the slide rails 14, 14 are all pulled out, the first,
The second table pieces 12 and 13 are arranged in a plane and can be used as one table board, for example, as a cooking table. Note that since the slide rails 14, 14 are made extremely sturdy, a load of up to about 70 kg on the tip of the first table piece 12 can be tolerated.

From this state, the first and second table pieces 12,1
3 in the table piece storage chamber 2, the handle front plate 12a of the first table piece 12 can be pushed in. That is, as shown in FIG. 6, the lengths of the slide rails 14, 14 contract and the first and second table pieces 12, 13 move on the slide rails 14, 14. At this time, the second table piece 13 is attached to the roller 17 attached to its rear end.
The guide tool 20 is pushed and rotated downward, moved on the slide rails 14, 14, and inserted into the table piece storage chamber 2. As shown in FIG. 7, the roller 17 rests on the upper surface of the lift guide 19 via its inclined surface. At this time, the strikers 15, 15 come into contact with the other ends of the guide tools 20, 20, and as shown in FIG. 8, the guide tools 20, 20 rotate and the guide rollers 21, 21 are urged upward, The front end of the second table piece 13 is lifted upward. Thereafter, as shown in FIG. 9, the first table piece 12 is inserted between the second table piece 13 and the slide rails 14, and is further pushed in. In addition, if too much force is applied to the pushing operation,
As shown in FIG. 10, since the guide rollers 21, 21 are rapidly rotated upward by the strikers 15, 15, the front end of the second table piece 13 springs upward and collides with the reinforcing bars 9, 9. Therefore, the second table piece 13 does not directly collide with the top plate 6 of the apparatus main body 1 and does not damage the top plate 6. In the end, as shown in FIG. 11, the first table piece 12 is smoothly inserted into the table piece storage chamber 2, the second table piece 13 is placed on top of this first table piece 12, and the front plate for handling is placed on top of the first table piece 12. 12a closes the opening 2a of the table piece storage chamber 2.

When using the table, hold the front plate 12a
Just pull it out to the front. That is, contrary to the above-mentioned accommodation operation, as shown in FIG. 12, the slide rail 1
4 and 14, their lengths are extended and the first table piece 12 moves toward the front side. At this time, the second
The table piece 13 also moves together with the first table piece 12 due to the frictional force with the first table piece 12. When the rear end of the first table piece 12 passes the guide rollers 21, 21, a gap is created between the second table piece 13 and the slide rails 14, 14, and the guide roller 21, 21 are rotated upward by the elastic force of the torsion spring 21a, and are further fitted into the groove 16 of the second table piece 13. For this reason, the first table piece 1
The striker 15 attached to the guide tool 20, 2
The first table piece 12 can be pulled out by moving without coming into contact with the other end of the table piece 12.

At this time, if the pulling force is strong and the first table piece 12 and the second table piece 13 suddenly move together due to the frictional force, as shown in FIG.
The second table piece 13 comes into impactful contact with the curtain plate 5 of the apparatus main body 1. Even if the curtain plate 5 is pulled in the drawing direction, the reinforcing bars 9 prevent the curtain plate 5 from falling off and being damaged.

As the first table piece 12 moves, the second table piece 13 moves to the slide rails 14,1.
4, the first table piece 12 and the second table piece 13 move in conjunction with each other via the connecting rod 18, and are pulled out of the table piece storage chamber 2.
As shown in FIG. 2, the first and second table pieces 1
2 and 13 are configured as one table board.

In addition, the table board can be used not only as a cooking table, but also as a desk, ironing board, and other multipurpose purposes.

In addition, in the above embodiment, two table pieces 1
Although one table plate is constructed from 2 and 13, the number of table pieces is not limited to this, and a plurality of table pieces may be used.In short, the reinforcing bar 9 is provided so that the main body of the apparatus can be formed by the table pieces. It is sufficient if damage to the top plate, back plate, and curtain plate can be prevented.

As explained above, according to the present invention, there is a slide rail and a slide rail for rearranging the table pieces housed therein as one table piece when pulled out, inside the device main body consisting of the top plate, the back plate, the curtain plate, etc. A support mechanism is provided which, when a table piece is pushed in, pushes up the other table piece using a striker attached to one of the table pieces and a guide tool attached to a slide rail to accommodate the table pieces in a stacked manner;
A crosspiece-shaped damage prevention body is installed between the top plate and the curtain plate and back plate between the support mechanism. Therefore, even if the table pieces collide with the curtain plate when pulling out the table pieces housed in the main body of the device and configuring them as a single table plate, the damage prevention member will keep the curtain plate strong. This prevents the curtain plate from falling off or being damaged from the main body of the device, or even if the table piece jumps up due to the striker and guide tool when storing the table piece inside the main body of the device. The damage prevention body located between the table piece and the top plate prevents the table piece from directly colliding with the top plate, reliably preventing damage to the top plate, improving durability, and making it possible to prevent the table piece from colliding directly with the top plate. This provides effects such as smoother loading and unloading of items.
