Abstract

(57) [Abstract] [Purpose] The armrest member provided on the game hall chair is attached to the end of the arm while it is securely stopped. [Arrangement] An armrest member 4 is attached to the tip of an arm 3 provided on the chair body. Here, an inclined tip surface 5 is formed at the tip of the arm 3, and the armrest member 4 is provided.
An inclined rear end surface 7 is formed at the rear end of the mounting hole portion 6. When the arm 3 is inserted into the mounting hole 6 of the armrest member 4, the inclined distal end surface 5 and the inclined rear end surface 7 are in contact with each other. As a result, the armrest member 4 is prevented from rotating with respect to the arm 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a game hall chair having an armrest.

[0002]

[Prior art]

 In the past, in pachinko halls, chairs have been installed in correspondence with pachinko game machines, and players are allowed to play while sitting on the chairs. This type of chair is designed in a shape suitable for a player to sit down and play.

By the way, a player who is playing a pachinko game machine is to play with the arm extended to the operation handle of the pachinko game machine, and when playing for a long time, the arm gets tired and the game is not absorbed. It's gone.

Therefore, it has been considered to provide an armrest to the chair. In other words, the arm is provided so as to project from the chair body, and an armrest member for supporting the player's elbow is attached to the tip of the arm. In this case, since the arm has a circular cross section and the mounting hole formed in the armrest member also has a circular cross section, the armrest member is attached to the arm while being prevented from rotating. As a means, it is common to screw or use a special detent.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, even though the armrest member is prevented from rotating with respect to the arm, it is simply screwed or partially fixed by using a special rotation stopper. Therefore, when a large rotational force is applied to the armrest member, the armrest member may rotate regardless of the stopping force of the screw or the rotation stopper. As a result, the armrest member may rotate from its proper position and may not be used as an armrest. Also, assembling work is troublesome in fixing the armrest member to the arm by using screws or rotation stoppers.

The present invention has been made in view of the above circumstances, and an object thereof is to fix an armrest member to the tip of an arm, and for an amusement hall that can reliably prevent the armrest member from rotating with a simple structure. To provide a chair.

[0007]

[Means for Solving the Problems]

 The present invention relates to a game hall chair provided for a pachinko game machine, in which the tip of the chair body is located at a position corresponding to the elbow of a player who is playing with the pachinko game machine, and the tip end has an inclined tip surface. An armrest having a mounting hole portion having a circular cross section, in which an arm having a circular cross section is formed, and an inclined rear end surface is formed in which the arm is inserted and the inclined distal end surface abuts in the inserted state. It is provided with members.

[0008]

[Action]

 When the arm tip is inserted into the mounting hole of the armrest member, the inclined tip end surface formed at the tip of the arm abuts the inclined rear end surface of the attachment hole. As a result, the armrest member is fitted in the arm in a non-rotating state, so that the armrest member will not rotate even if a large rotational force is applied to the armrest member.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Figure 3 shows the side of the chair body. In FIG. 3, the chair body 1 is rotatably supported with respect to the support column 2. In this case, the chair body 1 is installed in the support column 2 so as to face the pachinko game machine (not shown). Biased to the neutral position by means.

An arm 3 having a circular cross section is rotatably supported on the chair body 1, and an armrest member 4 is attached to the tip thereof. The arm 3 has an L-shape, and as shown in FIG. 3, the arm 3 is separated from the chair body 1 by a armrest member 4 to support a player's elbow and a storage position along the chair body 1. It is provided so as to be movable between.

FIG. 1 shows a cross section of an armrest member 4 attached to the tip of the arm 3. In FIG. 1, the tip of the arm 3 is cut in a slanted shape, whereby a slanted tip surface 5 is formed at the front end of the arm 3. A mounting hole 6 having a circular cross section is formed on the armrest member 4, and an inclined rear end surface 7 is formed on the rear end surface of the mounting hole 6. The tip of the arm 3 is inserted into the mounting hole 5 of the armrest member 4, and the slanted tip surface 5 of the arm 3 contacts the slanted rear end surface 7 of the mounting hole 4 in the inserted state. There is. As a result, the armrest member 4 is fitted to the arm 3 while being prevented from rotating (see FIG. 2).

On the other hand, a groove portion 3a is formed on the outer periphery of a portion of the arm 3 which is inserted into the armrest member 4, and a hexagon socket head cap screw 8 screwed to the armrest member 4 is engaged with the groove portion 3a. ing. With the above configuration, the armrest member 4 is attached to the arm 3 in such a manner that it is prevented from rotating and is prevented from coming off.

According to the above structure, the inclined distal end surface 5 is formed at the distal end of the arm 3, and the inclined rear end surface 7 is formed at the rear end of the mounting hole portion 6 of the armrest member 4. Since the slanted front end surface 5 and the slanted rear end surface 7 are brought into contact with each other, the assembly is different from the conventional example in which the armrest member is fixed to the arm with a screw or a rotation stopper. It can be easily performed, and the armrest member 4 can be securely stopped from rotating with respect to the arm 3. An adhesive may be used as a means for preventing the armrest member 4 from coming off the arm 3.

[0014]

[Effect of device]

 As is clear from the above description, according to the game room chair of the present invention, the inclined tip end surface is formed at the tip of the arm provided in the chair body, and the inclination is formed at the inner surface of the mounting hole of the armrest member. Since the armrest member is inserted into the arm with the slanted distal end surface abutting the slanted distal end surface and the slanted distal end surface, the armrest member is fixed to the distal end of the arm. It has an excellent effect that the armrest member can be securely stopped with a simple structure.
