Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing device for a cover that is an operation unit that is not normally exposed to the outside and that is opened and closed by an operator during operation.

[0002]

[Prior art]

 For example, the adjustment unit such as contrast adjustment does not usually need to be adjusted, but in special cases, it may be required to operate from the outside. Conventionally, such a part is provided with a cover, and the cover is removed for adjustment. To fix this cover, for example, it is fixed with a screw or a spring biased in the direction to close the cover is used.

[0003]

[Problems to be solved by the device]

 However, the screw type not only takes a long time to open and close the cover, but also has poor operability and the appearance is inferior. In addition, although the spring type can be easily opened and closed, the spring is urged in the direction to close the cover, so it is necessary to work while holding it down by hand during adjustment, and workability is poor.

The present invention has been made in view of such circumstances, and is intended to improve workability by fixing a cover.

[0005]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention is composed of a claw that is raised from each of the opposite sides of the cover closer to the end than the center, and an elastic wire that is stretched between the claws. The shaft includes a shaft and a bent portion that is bent in the direction of the first side near the claw, which is different from the opposite side from the center of the shaft, and the shaft has the first side when the cover is opened. Is attached to a position where it is pressed by the bent portion.

[0006]

[Action]

 When the cover 1 is closed, both ends 6a and 6b of the shaft 4 are in contact with the inside of the housing 7, and the force of the spring force in the closing direction of the cover 1 is urged. When the cover 1 is opened, the side 1c pushes the bent portion 5 outward of the side 1c, so that the side 1c is pressed and fixed by the boundary portions 5a and 5b.

[0007]

【Example】

 FIG. 1 is a perspective view showing an embodiment of the present invention. Reference numeral 1 is a cover provided in an adjusting portion of a device (not shown), the back side of which is the outer side of the device. Claws 2 and 3 are raised from the center of the opposite sides 1a and 1b of the cover 1 toward the lower side in FIG.

Holes 2a and 3a are formed in the tip portions of the claws 2 and 3, and a shaft 4 is inserted into the holes 2a and 3a, so that the cover 1 is rotated around the shaft 4. ing. ing.

The shaft 4 is made of elastic wire, and a bent portion 5 bent in the direction of the side 1c is provided near the center thereof. Further, both ends 6a and 6b of the shaft 4 are bent toward the inner surface of the housing 7 and pressed against the inner surface of the housing 7. Therefore, a spring force is applied, whereby the cover 1 causes the shaft 4 to move. It is biased and closed by the spring force of. As a result, the bent portion 5 is substantially parallel to the surface of the cover 1.

The mounting height of the shaft 4 is set so that when the cover 1 is rotated in the opening direction, the bent portion 5 slides along the side 1c and pushes the bent portion 5 toward the side 1c. Has been done.

As a result, the bent portion 5 is pressed by the side 1c and pushed outward (in the direction of the side 1c). As a result, the shaft 4 bends as shown in FIG. 2, and the rotating portion moves in the direction of the arrow, and at the position where the cover 1 is fully opened, the boundary portions 5a and 5b of the bent portion 5 become the side 1c of the cover 1. When they come into contact with each other, the rotational force of the shaft 4 that tries to close the cover 1 becomes 0, and the cover 1 does not close even if the hand is released.

Therefore, the cover 1 remains open, and the adjusting portion appearing there can be adjusted using both hands if necessary.

When the cover 1 is closed by hand when the cover is closed, the operation reverse to the above-described operation is performed, and the flexed shaft 4 can be removed. As a result, the state as shown in FIG. The ends 6a and 6b are urged in the closing direction by the spring force.

[0014]

[Effect of device]

 As described above, according to the present invention, the shaft around which the cover rotates is made of elastic wire, and the bent portion is formed at the center of the cover so that both ends of the shaft are brought into contact with the inner surface of the housing. Since the cover is biased in the direction to close it, when the cover is opened, one side of the cover pushes the bent part outwards to bend the shaft and the shaft bends, so the cover is fully opened. The side that pushes out the bent part in this state is fixed by friction with the bent part and does not close even if you release your hand, which has the effect of facilitating internal adjustment.
