JPH0643392Y2 - Key with light - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is used for automobile keys and the like. The present invention relates to a key with a light capable of illuminating a keyhole in a dark place.

[Outline] The present invention is a key with a light in which a light emitting element, a battery, an electrode, etc. are mounted on a grip portion of a plastic molded body that holds a metal piece on which a key is formed. By providing a clip member that closes the slit and fixes the battery at the mounting position, the battery can be replaced.

[Conventional technology]

It is known that a battery, a switch and a light emitter are mounted on a part of the key in order to illuminate the vicinity of the key hole when inserting the key into the key hole in a dark place. For example, the actual Kaisho 56-1
No. 49765, No. 58-44355, No. 61-107854
The publications such as Japanese Patent Publication No. 61-108459 and Japanese Utility Model Publication No. 61-108459 are known. In these, the grip portion of the metal piece on which the key is formed has a two-part structure, and the above-mentioned components are mounted therein.

[Problems to be solved by the invention]

However, since the combination of the two-divided gripping portions is actually joined with an adhesive or the like, it is difficult to replace the battery when the battery is exhausted.

Therefore, there is a drawback that a new key is recreated after the battery is exhausted or the key is used in the dark.

The present invention solves this drawback, and an object thereof is to provide a key with light in which the battery can be replaced.

[Means for solving problems]

The present invention comprises a metal piece on which a key is formed and a grip of a plastic molded body, the grip includes a light emitting element, a battery, and
The two electrodes for guiding the current of the battery to the light emitting element are internally provided, the plastic molded body includes two plate-shaped members sandwiching the head of the metal piece, and the battery has the two plate-shaped members. In a key with a light, which is a plate shape sandwiched between the two electrodes, one of the two electrodes includes a movable structure that disconnects the current path by the force of a finger applied from the outside of the grip, The plastic molded body is formed with a slit through which the battery can pass in the same plane as the plate-shaped battery at the mounting position, and is openably and closably mounted so as to close the slit. Is provided with a clip member for fixing the mounting position to the mounting position.

The clip member may be a plastic spring member, one end of which is rotatably attached to two plate-shaped members and the other end of which is locked to the plate-shaped members.

[Action]

Since the flat surface when the flat battery is in the mounting position is the same as the one surface of the inner edge of the slit having a shape through which the battery can pass, the battery can be taken in and out from the slit by using this flat surface as a guide.

The clip member, which is openably and closably attached so as to close the slit, fixes the battery at the mounting position while closing the slit, so that the battery does not shake when the key is used.

When the battery is exhausted, the clip member can be removed and the battery can be replaced with a new one.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. First
The drawing is an exploded view for explaining the structure of one embodiment of the present invention.

In this figure, there is provided a metal piece 1 on which a key is formed, and a grip portion provided on the head 1A of the metal piece 1 by a plastic molding at a position indicated by a two-dot chain line as indicated by an arrow A. Light emitting device 2 with external leads 2A and 2B on the grip
A battery 3, a circular electrode 4A and a plate-shaped electrode 4B, which are electrically connected to the external leads 2A and 2B, respectively, for guiding the current of the battery 3 to the light emitting element 2, are internally provided.

The plastic molded body includes the plate-like body 5 that firmly holds the head 1A of the metal piece 1, the light-emitting element 2, the battery 3, and the electrodes 4A and 4B.
And a plate-shaped body 6 for mounting and. The battery 3 is a lithium manganese battery, which is a disc-shaped battery, and has a circular electrode 4A and a plate-shaped electrode.
It is mounted by being sandwiched in the plane direction so as not to contact both electrodes simultaneously with 4B. At this time, the inner wall 6A of the plate-shaped body 6
Holds the battery so that it does not move due to vibration in contact with one peripheral part of the battery. The plate-shaped electrode 4B is a phosphor bronze-based elastic metal piece, and the electrode 4B pushes the battery 3 by pushing the button 5A of the plastic molded body provided in the approximate center of the plate-shaped body 5 from the outside with fingers. It is electrically connected to the electrode 4A via the cell, and the current path of the battery is in contact. When the finger is released, the electrode 4B returns and disconnects the current path.

FIG. 2 is an external view in which the parts shown in FIG. 1 are assembled, and the push button 5A is located substantially at the center of the plate-shaped body 5.

The feature of the present invention is that in FIG.
As shown by the arrow B, the surface of the circular electrode 4A at the mounting position of the disk-shaped battery 3 is arranged so as to be flush with the plane 6B of the plate-like body 6, and this plane 6B is one of the inner edges thereof. And a slit 6C is formed through which the battery 3 can pass.
The clip member 7 is provided so as to be openable and closable so as to close the 6C, and has a recess 7A for pressing and fixing the battery 3 against the inner wall 6A in a state where the slit 6C is closed. One end 7B of the clip member 7 fits into the recess 6D of the plate-shaped body 6.
Since the one end 7B is slightly smaller than the opening width of the recess 6D and the upper and lower edges thereof are formed in a circular shape, the one end 7B is the recess.
While being fitted in 6D, it will be rotatably mounted about this axis. The other end 7C is formed in a jaw shape, and a circular cutout portion 7E is provided inside the bent portion of the connecting portion 7D between the other end 7C and the one end 7B.

Therefore, this clip member 7 has a jaw-like portion of the other end 7C at one end.
When pushed in the direction of 7B, the connecting portion 7D is a spring member that bends inward in the vicinity of the cutout portion 7E.

The lower end of the jaw portion of the other end 7C fits into the other concave portion 6E of the plate body 6.

FIG. 3 is an explanatory view showing a mounting state of the clip member 7.

When replacing the battery, the clip member 7 can be easily removed by pushing the other end 7C portion of the clip member shown in FIG. 2 with a protrusion such as the tip of a ballpoint pen.

Further, the plate-shaped bodies 5 and 6 are welded and joined together to form an integral structure, so that the grip portion of the key becomes strong.

[Effect of device]

As described above, according to the present invention, the slit for inserting the battery is held by the clip member having the spring action to directly hold the battery alone, and also to lock the battery without contacting the electrode. There is an effect that it is possible to provide a key with light in which the battery can be replaced without making the grip portion thick.
