Description of the Related Art Generally, in a key telephone, when attaching a name card for recording abbreviated numbers, automatic dial points, etc., a method of attaching the name card to a recess provided on the front of the button telephone body is used. ing. By the way, simply attaching and attaching the name card to the concave portion is extremely inferior in appearance, and therefore, a lid that can be opened and closed is conventionally attached to the concave portion.

However, all of the conventionally used lid opening / closing devices for button telephones have a through hole for a bearing formed on each side surface of a recess formed on the front surface of the telephone body. The shafts formed on the side surfaces of the ends of the lids are inserted into each of them and the lids are attached so that the lids can be freely opened and closed. When the telephone body is turned upside down and lifted, the lid naturally opens and closes. Further, in this type, the shaft provided on the lid or the lid itself may be damaged when the lid is opened beyond a predetermined angle, which is not preferable in terms of use.

The present invention eliminates the above-mentioned conventional drawbacks, the lid can be easily attached / detached with a simple structure, an appropriate degree of moderateness is given when opening / closing the lid, and the lid is set in advance to a certain level. It is an object of the present invention to provide an excellent lid opening / closing device in which the lid does not fall off due to its force when the opening is wider than the angle, and the shaft and the lid itself are not damaged.

Means for Solving the Problems In order to achieve the above object, the present invention provides a container having a recess for storing a predetermined container, a lid for opening and closing the recess of the container, and both ends of the container. A pair of arms each having a shaft inside the free end and having elasticity,
A bearing through hole provided in the lid so as to face the shaft, and the shaft is fitted into the through hole so that the lid is openably and closably attached to the container about the shaft, and An elastic piece provided at the center of the end edge of the container, and an outer periphery of the elastic piece formed at the center of one end of the lid when the lid has a first opening / closing angle with respect to the container. A cam piece that is pressed against the surface to provide a moderation for opening and closing the lid, and an outer peripheral surface of the elastic piece that is attached near the cam piece when the lid has a second opening and closing angle with respect to the container. A notch that presses against the lid to provide moderation for opening and closing the lid, a projecting piece for a guide integrally formed on the inner surface of one end of the lid, and a notch and the arm, which is provided between the arm and accommodates the projecting piece. And a guide projection, and the shaft is configured so that when a large external force in the opening direction is applied to the lid, these And direction is elastically deformed to open the arm relative to the lid, shaped fitting between the through hole is released, is obtained by the configuration of setting the length.

Therefore, according to the present invention, the cam piece, the notch, and the elastic piece can prevent the careless opening and closing of the lid by opening and closing the lid at the first and second opening and closing angles, and a large external force can be applied to the lid. The lid will fall off even if a force is applied, and the lid and shaft are less likely to be damaged, and with the lid closed, even if the projection is guided by the guide projection and the lid is distorted, it can be corrected. .

Embodiment FIG. 1 to FIG. 5 show the construction of an embodiment of the lid opening / closing device of the present invention. 1 to 5, 1 is a case such as a telephone body, 2 is a panel mounting recess formed on the front surface of the case, 3 is an edge of the recess 2, and a guide for opening and closing the lid is formed on the upper surface. A jetty with an arc-shaped guide groove 4 to be a guide, 5 and 5 are projections for guides integrally formed close to the jetty 3, respectively, and 6 is mounted in the recess 2 and a name card 7 or the like is attached to the front surface. A panel having a recess 8 for accommodating and constituting a container, 9 and 9 are shaft-forming arms integrally formed on both sides of the end of the panel 6, and 10.
0 is a shaft for mounting a lid integrally formed on the surfaces of the shaft forming arms 9, 9 facing each other, and 11, 11 are shaft forming arms 9, 9.
Cut grooves formed on both sides of the end of the panel 6 in order to have sufficient elastic force, 12 and 12 are notches formed on the edge of the panel 6 into which the projections 5 for guiding are fitted, respectively. 1
3 is an elastic piece integrally formed at the center of the edge of the panel 6 and has a locking claw 14 at the tip, and 15 has bearing ribs 16 and 16 on both sides of one end, respectively. The through holes 17 and 17 for bearings formed in the ribs 16 and 16 of the
By fitting the shafts 10 and 10 formed on 9, 9
A lid mounted so as to be rotatable around 0 and 10, 18 and 18 are projecting pieces for guides integrally formed on the inner surface of one end of the lid 15, and 19 is integrally formed at the center of one end of the lid 15. When the lid 15 is opened and closed, the cam piece 19 engages with the claw 14 of the elastic piece 13 to provide an appropriate degree of moderation for opening and closing the lid 15, and 20 is a cam piece 19 having one end edge of the lid 15 formed.
Similarly, a notch that engages with the claw 14 to give an appropriate degree of moderation to the opening and closing of the lid 15, and a protrusion 21 formed at the other end of the lid 15 that acts as a handle when the lid 15 is opened and closed. The cam piece 19 is configured to provide a moderation for opening and closing the lid 15 in a state in which the lid 15 is closed and in a state in which the lid 15 is opened at a predetermined fixed angle, for example, about 90 degrees, and the notch 20 is, for example, The lid 15 is configured to be moderately opened and closed with the lid 15 opened about 120 degrees. When the lid 15 is opened about 120 degrees or more, the outer surface of the lid 15 comes into contact with the edge of the jetty 3 formed on the case 1 so that the lid 15 cannot be opened any more.

In the above embodiment, the panel 6 has a shaft as shown in FIG.
The 10 parts are mounted in the recess 2 so as to face the guide groove 4. When mounted in this way, the protrusion 5 is inserted into the notch 12. In this state, if the through hole 17 is fitted in the shaft 10 and the lid 15 is attached, the lid 15 can be attached rotatably around the shaft 10.
When the lid 15 is closed, the projection 18 is guided by the projection 5 and the lid 15 is closed.
Even if there is distortion in the image, it can be corrected. Then, this state is maintained until the lid 15 is opened by a certain angle or more. When the lid 15 is closed, the claws 14 of the elastic piece 13 are elastically pressed against the outer peripheral surface of the end portion of the cam piece 19, and the lid 15 is moderated by the elastic force of the elastic piece 13 so as to maintain the closed state. Have been given.

When the lid 15 is opened using the protrusion 21 provided on the lid 15, the elastic piece 13
The claws 14 slide relative to each other along the outer peripheral surface of the cam piece 19, and fit the notches formed on the outer peripheral surface of the cam piece with the lid 15 opened approximately 90 degrees, so that the lid 15 has an appropriate moderation. give. Therefore, as shown in FIG. 5 (A), the lid 15 can be self-supporting in this state. Then, when the lid 15 is further opened, the fifth
As shown in FIG. (B), when the claw 14 of the elastic piece 13 is fitted into the notch 20 formed in the edge of the lid 15 when the lid 15 is opened approximately 120 degrees, the lid 15 should be given a proper moderation in this state again. become. When the lid 15 is further opened, the outer side surface of the lid 15 comes into contact with the edge of the jetty 3 as shown in FIG. 5C, and the lid 15 cannot be opened anymore.

By the way, according to the above-mentioned embodiment, since the arm 9 for forming the shaft has a relatively large elastic force and the shaft 10 is formed to be relatively short, further force is applied to the lid 15 to cause the shaft 15 to move. When the lid 15 is wide open as shown in (D), the engagement between the through hole 17 formed in the lid 15 and the shaft 10 is released. Therefore, according to the above-described embodiment, even if a large opening direction force is applied to the lid 15, the lid 15 is not damaged and the shaft 10 is not broken by the force. Therefore, in this case, it is possible to restore the original state only by attaching the lid 15 that has fallen off again, which is extremely advantageous in practical use.

Effect of the Invention As is apparent from the above embodiment, the present invention prevents the inadvertent opening and closing of the lid by opening and closing the lid by the action of the cam piece, the notch and the elastic piece. Even if a large external force is applied to the lid, the lid will fall off and the lid and shaft will be less likely to be damaged.When the lid is closed, the protrusion is guided by the guide projection and the lid is distorted even if it is distorted. It has the effect of being able to.
