DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table device attached to a wall surface such as a train seat back.

[0002]

2. Description of the Related Art In a conventional wall table apparatus, a base end of a table plate is connected to a fixed rail plate by a hinge pin passing through a shaft hole at a lower end portion of a pair of left and right fixed rail plates. The end is connected to an intermediate portion of the table plate by a fixed shaft pin, and the movable shaft pin at the upper end of the support plate is fitted into a vertical guide slot of the fixed rail plate. Therefore, when the table plate is pulled out and rotated about the hinge pin to the use position, the movable shaft pin moves to the lower part of the guide slot, and the table plate 6 is held in a horizontal state by the support plate.

When the table plate is lifted and rotated about the hinge pin after use, the movable shaft pin moves to the upper part of the guide slot, and the table plate comes to the storage position along the wall surface. In order to secure a wide seat space, it is necessary to keep the table plate in the storage position. In the conventional device, a stopper-fitting made of a curved leaf spring is provided on an upper portion or a wall surface of the fixed rail plate, and the bending of the leaf spring is performed. The locking portion is elastically engaged with the tip of the table plate. However, in the configuration of the leaf spring holding type, the holding function of the table plate is deteriorated due to loosening due to aging of the elastic force of the leaf spring and the loosening of the leaf spring mounting portion, and the table plate is rattled due to vibration or the like,
It may fall out of the raised storage position. Further, the addition of the leaf spring and its holder member hinders a reduction in manufacturing and assembling cost of the entire apparatus.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to stably and accurately hold a table plate without rattling due to vibration, not to decrease the holding function due to aging, and to reduce manufacturing and assembly costs by reducing the number of parts. An object of the present invention is to provide a wall table device capable of saving money.

[0005]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. A wall table device according to the present invention includes a pair of right and left fixed rail plates 1, 1 fixed to a wall surface 5.
1 and a fixed rail plate 1 at a base end thereof by a hinge pin 12.
And a pair of left and right support plates 2 whose base ends are connected to a middle portion of the table plate 6 by fixed shaft pins 11, and are vertically guided by the fixed rail plate 1. A slot 8 is formed, and the movable shaft pin 10 at the upper end of the support plate 2 is fitted into the guide slot 8,
Receiving groove 7 with which locking pin 13 at the tip of table plate 6 is disengaged
Is formed on the upper end side of the fixed rail plate 1 so as to approach the wall surface 5 toward the lower side, and the shaft hole 9 through which the hinge pin 12 is passed is formed on the fixed rail plate 1 so as to approach the wall surface 5 toward the lower side. Formed at the lower end.

In this table device, when the table plate 6 is pulled out and rotated about the hinge pin 12 to the use position, the movable shaft pin 10 of the support plate 2 moves to the lower portion of the guide slot 8 of the fixed rail plate 1 and is fixed. Support plate 1 that is tilted and rotated with respect to table plate 6 about axis pin 11
However, as shown in FIG. 2, the table plate 6 is held in a horizontal state. When the table plate 6 is pulled up and rotated around the hinge pin 12 after use, the movable shaft pin 10 moves to the upper part of the guide slot 8, the support plate 2 is arranged parallel to the fixed rail plate 1, and the table plate 6 is Come to the storage standby position along 5. In this standby position, as shown in FIG. 8, the locking pin 13 at the distal end of the table plate 6 faces directly above the receiving groove 7 at the upper end of the fixed rail plate 1, and the hinge pin 12 is At the upper end.

When the user releases his hand from the table plate 6 in such a position, the table plate 6 descends by its own gravity, and the locking pin 13 enters the receiving groove 7 and moves to the lower portion thereof. 12 moves to the upper part of the shaft hole 9. Then, in the course of this movement, the table plate 6 is drawn to the wall surface 5 side. In the storage completed position,
Since the locking pin 13 is deeply engaged with the receiving groove 7, the locking pin 13 does not fall off due to vibration or the like.

[0008]

In the embodiment shown in the drawings, a pair of left and right fixed rail plates 1 are formed of angle-shaped members, and a guide slot 8 is provided in one plate side portion 1a arranged at right angles to a wall surface 5. The receiving groove 7 is provided inside the upper end of the plate side 1a.
Is welded. The other plate side portion 1b arranged in parallel with the wall surface 5 is fastened and fixed to the wall surface 5 by screws 14. The support plate 2 is constituted by a flat bar, and when the table plate 6 is stored, the fixed rail plate 1
And between the left and right side surfaces of the table side 6 and the table plate 6.
The fixed shaft pin 11 at the base end of the support plate 2 is attached to the left and right side surfaces of the table plate 6 by brackets 4 made of an angle-shaped member. Bracket 4 is screw 1
6 fastens and is fixed to the table plate 6.

A hinge bracket 3 made of an angle-shaped material is fastened and fixed to a base end of the table plate 6 by a screw 15, and a hinge pin 12 is passed through a protruding end 3 a of the hinge bracket 3. The locking pins 13 are fixed to the left and right side surfaces of the tip of the table plate 6.

[0010]

As described above, in the wall surface table device of the present invention, the base end of the table plate 6 is connected to the lower ends of the pair of left and right fixed rail plates 1 and 1 by the hinge pins 12.
The base ends of the pair of left and right support plates 2 are fixed to the fixed shaft pins 11.
The movable shaft pin 10 at the upper end of the support plate 2 is fitted into the vertical guide slot 8 of the fixed rail plate 1 so that the locking pin 13 at the tip of the table plate 6 is disengaged. The receiving groove 7 is formed on the upper end side of the fixed rail plate 1 so as to approach the wall surface 5 as it goes downward, and the fixed rail is formed so that the shaft hole 9 through which the hinge pin 12 is passed approaches the wall surface 5 as it goes downward. Formed at the lower end of the plate 1,
In the final stage in which the table plate 6 is pulled up and fixed between the fixed rails 1 and 1 along the wall surface 5, the locking pins 13 are provided.
Moves to the lower part of the receiving groove 7, while the hinge pin 12 moves to the lower part of the shaft hole 9, so that the table plate 6 is stably held while being drawn to the wall surface 5, and rattling due to vibration is accurately prevented. You.

Using the gravity of the table plate 6 itself, the locking pin 13 and the hinge pin 12 are received in the receiving groove 7 and the shaft hole 9 respectively.
The holding function is not lowered by aging as in the conventional device using a curved leaf spring, and the durability is excellent. In addition, since a required holding function is obtained only by changing the shape of the receiving groove 7 and the shaft hole 9 without additionally using a special part such as a leaf spring, the number of parts is reduced and the manufacturing and assembly cost is reduced. be able to.
