Description

[Detailed Description of the Invention] (Field of Industrial Use) The present invention relates to a retractable key that is normally used as an accessory such as a pendant, and that pops out when the key is desired to be used as a key.

(Prior Art) Generally, keys are used alone or with a key chain attached.

(Problems to be Solved by the Invention) Conventional keys are used either as a single key or with a key chain attached, but the key plate itself is exposed, so there is a problem in that it lacks fashionability.

The present invention was devised in view of these problems, and its purpose is to provide a retractable key with high fashionability. Another object of the present invention is to provide a key that can reliably support the key plate and has a simple structure.

(Means for Solving the Problems) The present invention to solve the above problems includes a key plate having a narrow key part formed in a predetermined shape and a wide lock part with protrusions carved in the width direction; A case in which an insertion hole is drilled at the bottom in a shape in which the key portion can be inserted and the lock portion cannot be inserted, and through holes are bored at opposing positions on both narrow sides; a spring disposed with the key plate and biasing the key plate in the direction of the insertion hole; a rod-shaped stopper portion fitted in the through hole in the side portion of the case so as to be movable laterally; and these stopper portions. An elastically deformable plate beam connects the intermediate portions of the stopper portions so that the rod-shaped stopper portions maintain a parallel state, and when the rod-shaped stopper portions are in the parallel state, the end face thereof enters the movement locus of the lock portion of the key plate. When the key plate is stored in the case, one end surface of both rod-shaped stopper portions abuts each end surface of the lock portion of the key plate on the key portion side, and the key plate is When the key part protrudes from the case, the end faces of the other rod-shaped stopper parts are close to the end faces of the lock part of the key plate on the opposite side to the key part side, and the key plate is stored in the storage direction. It is characterized by comprising a substantially H-shaped lock stopper that restricts the movement of the lock stopper.

(Function) In the retractable key of the present invention, the spring constantly applies a biasing force to move the key plate toward the insertion hole of the case. Therefore, when the end face of the lock stopper and the end face of the insertion hole of the key plate lock portion are released from contact, the key portion of the key plate projects out of the case and can be used as a key.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.

In FIGS. 1 to 3 showing the first embodiment, 1 is a key plate which includes a narrow key portion 1a formed in a predetermined shape and a wide protruding shape that can be locked with a lock stopper 2. Lock part 1b
It has Reference numeral 2 designates a lock stopper having a substantially H-shape, and includes bar-shaped stopper portions 2c, 2d located on both sides of the key plate 1;
and an elastically deformable arc-shaped plate beam 2a that connects the middle portions of the plates so that they remain parallel. A protrusion 2b is provided at the center of the plate beam 2a toward the center of the arc, and the protrusion 2b fits into a groove 3a of a plate 3 inserted into the case 4 to prevent the lock stopper 2 from falling off. . An insertion hole 4a is formed in the bottom of the case 4 and has a shape that allows the key portion 1a to pass through but not the lock portion 1b, and through holes are formed at opposing positions on both narrow sides. , while the plug 4 at the top of the case 4
b is removable for inserting the key plate 1 and plate 3. A plate spring 6 is inserted in a compressed state between the end surface of the key plate 1 opposite to the key portion 1a and the plug 4b of the case 4, and urges the key plate 1 toward the insertion hole 4a. There is. The rod-shaped stopper portions 2c and 2d of the lock stopper 2 are fitted into the through holes in the side portions of the case 4 so as to be movable laterally, respectively, and when in a parallel state, their end surfaces are aligned with the locus of movement of the lock portion 1b of the key plate 1. It is formed to enter the That is, when the key plate 1 is stored in the case 4, one end surface B of both rod-shaped stopper portions 2c and 2d abuts each end surface A of the lock portion 1b of the key plate 1 on the key portion 1a side, and the key When the key portion 1b of the plate 1 protrudes from the case 4, the end surface E on the other side of both rod-shaped stopper portions 2c, 2d
are close to each end surface D of the lock portion 1b of the key plate 1 on the opposite side to the end surface on the key portion 1a side, and are adapted to restrict movement of the key plate 1 in the storing direction.

Next, the operation of the embodiment having the above configuration will be explained. As shown in FIG. 2, when the entire key plate 1 is stored in the case 4, the end face A of the lock part 1b of the key plate 1 on the key part 1a side and the end face of the rod-shaped stopper parts 2c, 2d of the lock stopper 2 B comes into contact with the key plate 1, and the urging force of the plate spring 6 prevents the key plate 1 from moving into the insertion hole 4a. Here, the rod-shaped stopper part 2 of the lock stopper 2
When the protrusions 2e and 2f on the side of the insertion hole 4a of c and 2d are pushed inside the case 4 against the elastic force of the plate beam 2a, the protrusions 2g and 2h on the side opposite to the insertion hole 4a move to the outside of the case 4. Then, the contact between the end surfaces A and B is released, and the key plate 1 is released from the plate spring 6.
The key portion 1a of the key plate 1 is inserted through the insertion hole 4a and the case 4 is moved to the side of the insertion hole 4a by the urging force of
As shown in FIG. 3, the key plate 1 stops when the end surface A on the side of the key portion 1a comes into contact with the bottom surface of the case 4, and is ready to be used as a key. When the key part 1a is inserted into the key ring for locking or unlocking, a reaction force in the direction of pushing the key plate 1 into the case 4 is generated by the key plate 1.
However, even if this reaction force is greater than the elastic force of the plate spring, it will not move into the case 4 until the end surface D on the side opposite to the key part 1a of the lock part 1b of the key plate 1 hits the stop parts 2c, 2d of the lock stopper 2.
Since the key part 1a stops when it comes into contact with the other end surface E, the movement of the key part 1a is extremely small, and the key part 1a does not enter into the case.

Next, when storing the key plate 1 in the case 4, first remove the protrusions 2g and 2h of the lock stopper 2.
is pushed inward against the elastic force of the plate beam 2a to move the other protrusions 2e and 2f to the outside of the case, and after releasing the contact between the end surfaces D and E, a force greater than the urging force of the plate spring 6 is applied. Then, push the key plate 1 into the case 4. As a result, the key plate 1 moves into the case, and the end surfaces A and B come into contact with each other, completing storage.

In the case of a retractable key configured as in this embodiment, simply by pressing the protrusion of the lock stopper 2, the urging force of the plate spring 6 causes the key part 1a of the key plate 1 to protrude outside the case 4, and it can be used as a key. . Furthermore, when the key plate 1 is not used as a key, the entire key plate 1 can be stored in the case 4, so that by adding various designs and functions to the case 4, it is possible to improve fashionability and add value. For example, it is easy to give the case 4 a trendy design, provide a light, or provide a digital clock.

FIG. 4 is a diagram showing a second embodiment of the present invention. In this embodiment, a light 7 is provided at the bottom of the case 4 of the retractable key of the first embodiment described above.
A push button switch 8 is disposed near the lock stopper 2. According to this configuration, when inserting the key plate 1 into the key cylinder in a dark place, the light from the light 7 allows the key plate 1 to be easily inserted into the key cylinder.

FIG. 5 is a diagram showing a third embodiment of the present invention. This embodiment has a digital clock 9 on the side of the lighted retractable key case of the second embodiment.
is arranged.

Note that the present invention is not limited to the above embodiments. For example, a compression spring may be used instead of the plate spring 6, and one end of the compression spring may be brought into contact with the end surface of the key plate 1, and the other end may be brought into contact with the plug 4b.

(Effect of the invention) As explained above, according to the key of the invention,
When not in use as a key, the entire key plate is stored inside the case. Therefore, the case itself can be given various designs and functions to enhance its fashionability and added value. Further, since the lock stopper is formed in a substantially H-shape with bar-shaped stopper portions on both sides, the key plate can be held down on both sides, and the key plate can be supported reliably.
Furthermore, the lock stopper itself is an operation button that can return to its original position by itself when it is released, reducing the number of parts and simplifying the configuration.
