Description

  The present invention relates to an armchair device for a game room chair.

In the amusement hall, the distance between the neighbors is narrow, and compact chairs are used to facilitate seating. By the way, in the electric pachinko machine, since the state of holding the handle of the pachinko machine with the right hand for a long time is maintained, there is a problem that the right arm becomes tired.
Therefore, an armrest device that can be stored so as not to get in the way at the time of taking off and seating has been developed (see, for example, Patent Documents 1 and 2).

The armrest device for a pachinko chair disclosed in Patent Document 1 is provided with a substantially L-shaped arm having an armrest fixed on an upper end thereof, which is pivotable at a lower portion of a seat portion.
Further, the armrest device of Patent Document 2 can be stored when not seated, and the height of the armrest body can be adjusted in accordance with the physique of the player. That is, an arm with an armrest fixed on the upper end is attached to the lower portion of the seat plate so as to be tiltable back and forth, and a plurality of engagement holes are formed in the upper end of the arm, and the engagement bracket can be engaged with and disengaged from the engagement hole. The armrest body equipped with is slidable along the arm.

  By the way, the same chair is used in the game hall, and it is used by an unspecified number of people of various physiques. The appropriate position of the armrest depends on the player's physique, but it is painful to sit in the same posture for a long time even for the same player, so the seating posture may change. Along with this, it may be necessary to change the position of the armrest. Like the armrest device of Patent Document 2, there is a problem that it cannot be said that it is an optimal armrest for the player just by changing the height of the armrest.

  Therefore, an object of the present invention is to provide an armrest device for a game room chair that can be easily and arbitrarily changed not only in height adjustment but also in position on a plane.

  In order to solve the above-described object, the armchair for a gaming chair according to the present invention is configured as follows. That is, a strut cover with an armrest mounted on the top surface is slidably fitted to the upper end of the strut, and the base end of the strut is pivotally attached to a seat receiver, and the strut cover is placed in the strut cover. In an armchair device for a gaming chair that is provided with a locking bracket that can be engaged with and disengaged from a plurality of locking grooves formed at the upper end of the armchair, and the height of the armrest can be adjusted. Is formed so as to be rotatable with a support shaft penetrating the elongated hole, and a return spring for automatically returning the armrest to the rear is provided.

In this armrest device, the armrest is adjusted and fixed to an appropriate height, but the plane position is freely movable within a certain range.
The support column is rotatably attached to the seat support and is configured to be held in the use position and the storage position. This holding configuration is not particularly limited.
The armrest height adjusting means may be formed by forming a plurality of locking grooves at the upper end of the column and providing a locking bracket that can be manually engaged with and disengaged from the column cover that is slidably fitted to the column.

The armrest is attached to the column cover so as to be rotatable by a support shaft. And the long hole of the longitudinal direction which penetrated the spindle was provided in the bottom part of the armrest.
The movement of the armrest on the plane may be limited to a certain range so that the long hole is not exposed. As described in claim 3, it is preferable that the armrest support is fixed to the upper end of the column cover, and a convex portion is provided on the upper end of the armrest support so as to be loosely fitted in the long hole at the bottom of the armrest base. .

  The armrest is provided with a return spring for automatically returning to the rear when not in use. According to a second aspect of the present invention, the sliding member through which the support shaft passes is provided on the long hole of the armrest base, and one end of the return spring is locked to the sliding member, and the other end is mounted on the armrest. It is good to lock at the front center of the table.

  An armchair for a gaming chair according to the present invention has a long hole in the longitudinal direction formed at the bottom of an armrest, and is attached to a column cover so as to be rotatable with a support shaft penetrating the long hole. Since the return spring for automatically returning to the rear is built in, the armrest can be freely moved to an appropriate position after the player has adjusted the height to be constant. In addition, when the hand is returned from the game stand such as when leaving the seat, the armrest automatically returns to the rear end position of the long hole.

In addition, as described in claim 2, if the armrest is provided with a sliding member through which the support shaft penetrates and the return spring is locked, the device can be simplified and less trouble occurs.
According to a third aspect of the present invention, an armrest receiving base is fixed to the upper end of the column cover, and a convex portion loosely fitted to the long hole in the bottom of the armrest base is fixed to the upper surface of the armrest base. The movement can be limited easily and reliably.

An embodiment of an armchair for a gaming chair according to the present invention will be described with reference to the drawings.
FIG. 1 is a side view showing the entire game room chair, and an armrest device having an armrest 10 for placing a right elbow on the upper end of a support arm 20 is provided.
In FIG. 1, 3 is a leg, 4 is a telescopic shaft, and 5 is a backrest.
The longitudinal section of the armrest device is shown in FIG. 2, but in order to help understanding, an explanation is given with reference to an exploded perspective view of the support arm 20 (FIG. 3) and an exploded perspective view of the armrest 10 (FIG. 4). To do.

The support arm 20 includes a support column 21 formed by bending an elliptical tube into an L shape, and a support column cover that is externally fitted to the upper end side of the support column 21 and to which an armrest receiving base 30 is attached via an elbow plate 29. 24 and a lever 25.
The support column 21 has a base end portion attached to the seat 2 so as to be rotatable by a bearing, and is held by an elastic body 23 attached to the bearing in a use position indicated by a solid line and a storage position indicated by a one-dot chain line in FIG. I try to do it. The elastic body 23 uses a fine cell foamed urethane elastomer having a large deformation amount, and is incorporated in an elliptical shape at the use position and the storage position.

  A lever 25 is inserted into the upper end of the column 21, and the upper end of the lever 25 is attached to the column cover 24 so as to be rotatable by a pin 28. A locking groove 21 a having a plurality of (here, six) locking portions 21 b is formed on the upper end side of the support column 21, and the lower end portion of the lever 25 is engaged with the locking groove 21 a. A locking metal fitting 26 is provided. Further, a push piece 25 a connected to a push button 24 a provided on the support cover 24 is provided at the front portion of the lever 25.

  With this configuration, when the push button 24a is pushed, the push piece 25a of the lever 25 is pushed and pivots backward (counterclockwise) about the pin 28 as a fulcrum, and the lock fitting 26 is locked. It moves to the groove | channel communicated vertically with the groove | channel 21a. In this state (while pressing the push button 24a), the column cover 24 can be held and moved in the vertical direction. When the push button 24a is released, the lever 25 is returned to the front by the return spring 27, and the locking fitting 26 is locked to the locking portion 21b at that height. In the figure, reference numeral 22 denotes a spacer.

The armrest base 10 has an elbow pad 11 attached to the upper surface of an armrest frame 12 and is attached on an armrest receiving base 30 at the upper end of a column 21.
A long hole 12 a is formed on the bottom surface of the armrest frame 12, and an elliptical convex portion 30 b is formed on the top surface of the armrest receiving base 30. The convex portion 30b has a smaller area than the elongated hole 12a and is loosely fitted. The sliding member 13 is provided on the upper surface of the long hole 12 a and is attached to the armrest receiving base 30 by the support shaft 14. That is, the support shaft 14 is attached through the shaft hole 13 a of the sliding member 13, the long hole 12 a of the armrest frame 12, and the shaft hole 30 a of the armrest receiving base 30. Reference numeral 17 denotes a washer.
A pin 16 is attached to the front end portion of the sliding member 13, and a return spring 15 having one end locked to a spring receiver 12 b provided at the front portion of the armrest frame 12 is connected.

Since the armrest 10 is configured as described above, the armrest 10 can be rotated with respect to the armrest receiving base 30 in the front-rear direction and the left-right direction within a certain range. This fixed range is a range of loose fitting with the convex part 30b of the armrest receiving base 30 which the long hole 12a of the armrest frame 12 has. Specifically, as shown in FIG. 6, the elbow pad 11 is movable within a range indicated by a two-dot chain line.
When the elbow pad 11 is not in use, the return spring 15 is positioned in the horizontal direction at the rearmost portion indicated by the solid line. The return spring 15 is a spring having a weak spring force as long as it can be returned.

Next, the operation of the armchair for a gaming chair thus configured will be described.
When the armrest device is not in use, the armrest device is normally stored on the backrest side, as shown by a one-dot chain line in FIG. At this time, the armrest 10 is positioned at the rear end by the return spring 15.
When a player uses an armrest device, the player first rotates the armrest device forward. When the armrest device is rotated to the use position, the elastic body 23 becomes an elliptical and locked state, and the support arm 20 is held in that posture.

Next, the armrest 10 is adjusted to an optimum height for the player. For this operation, the push button 24a is pushed, the support cover 24 is slid up or down, and the push button 24a is released at an appropriate position. By this operation, the locking metal fitting 26 is changed from the initial position of the locking portion 21b to the position of the optimum height of the player.
The player places the part of the elbow to be supported on the elbow pad 11 and pushes it forward to grab the handle of the pachinko machine and play.

  Players often get tired and change their posture, but if the elbow is moved accordingly, the position of the armrest 10 will also follow freely, so an operation for adjustment at the position on the plane is necessary. do not do. When the elbow is separated from the armrest 10, the armrest 10 is automatically returned to the rear end by the return spring 15. In addition, the adjustment of the height of the armrest base 10 and the movement in the front-rear direction at the use position of the armrest device are within a range indicated by a one-dot chain line in FIG.
