Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pop-out key.

[0002]

2. Description of the Related Art As a key holder that can be protruded from a grip body only when used and used when not in use, a key holder that can be stored in the grip body is, for example, Japanese Utility Model 2-21991.
Japanese Unexamined Patent Application Publication No. HEI 9-203 (1999) is known. In this conventional example, the key blade is rotatably supported on a grip body formed in a rectangular shape, and can be stored in a storage space formed on a side edge of the grip body when not in use. At the time of use, the operating roller can be operated to be ejected from the grip body.

However, in the above-described conventional example, the key blade is stored in the grip body by pushing the side edge of the key blade into the grip body. It is necessary to push in the key blade with a claw or the like in order to fit it in, so that there is a problem that operability is poor. In particular, when a deep key code groove is cut at the tip of the key blade, there is a problem that the push-in cannot be performed because the push-in allowance is not substantially secured.

In the above conventional example, the key blade is 90
° Rotate to change between the storage posture and the pop-out posture, so in the protruding posture of the key blade, the long side of the grip body is located at the base end of the key blade,
The length in the orthogonal direction at the base end of the key blade becomes longer.
As a result, a large rotating space for the grip body is required on the surface of the key cylinder device, and there is a problem that the usability is poor.

In order to solve this problem, for example, as described in Japanese Utility Model Laid-Open Publication No. 6-65580, the key blade is rotated by 180 ° so that the key blade is positioned at the center line of the key blade in the protruding position. Can be set to minimize the width dimension of the distal end portion of the grip body. However, in this case, since almost the entire area in the grip body is used as a storage space for the key blade, for example, when a radio wave transmitting device or the like is stored in the grip body, there is a problem that the storage space becomes too small. In addition, in order to press the side edge of the key blade and store it, it is necessary to set the storage space for the key blade at the edge of the grip body. However, since one side of the grip body is determined in advance, there is a problem that the degree of freedom in design is almost lost.

[0006]

1 is formed so as to have a hypotenuse portion 4 intersecting at an acute angle with respect to 1 and is formed so as to become gradually narrower toward the tip, and the key blade 2 is stored along the hypotenuse portion 4. Can be.

The key blade 2 is stored in an oblique position with respect to the center line c1 in the protruding position of the key blade 2. As a result, the center line c1 of the grip body 1 can be used as a space for accommodating, for example, a radio wave transmitting device or a battery. In addition, since the distal end portion 1a of the grip body 1 is gradually narrowed toward the distal end,
A large operation space for the grip body 1 is not required on the surface of the key cylinder device, and the usability is improved.
