Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a key chain that is attached to the head of a key, particularly a car key, to cover and decorate the head of the key, and also serves as a holder.

``Prior Art'' A car key is used to start the engine, but in order to turn it clockwise after inserting it into the keyhole, the head of the key must be shaped so that it is easier to apply force. The key was large and ungainly in shape, and the head of the key protruded into the interior of the car while the car was being driven, making it unsightly and unsightly.

Further, conventional key holders are simply used to hold keys together, and do not have any shape that makes it easier to apply force when rotating the keys.

``Problems that the invention aims to solve'' Conventional key chains do not have any function as a cover for the head of the key or as a decorative accessory, and when starting the engine, the key is rotated in the direction of rotation. The problem was that it was difficult to apply force to rotate it.

"Means for Solving the Problems" The present invention was made in view of the above-mentioned problems, and includes a bottom part of the top cover 8 having a protrusion 6 on the front side, and a recessed part 12 for accommodating the protrusion 6. The bottom of the lower lid 8, to which a rotating body 14 having a locking ring 22 is rotatably screwed, is pivotally supported on the tip of a screw punch 13 attached to the front, and is attached to open and close. Lower lid 8
The key insertion hole 35 is provided at the bottom of the upper lid 3, and the housing part 20 for housing the head of the key is provided therein as a means for solving the above-mentioned problems.

``Function'' In addition to covering the head of the key, the part that protrudes into the car can be decorated with accessories to double as a holder.

"Example" An example of the present invention will be described based on the drawings.
1, the outer shape is approximately the same as the head 31 of the key 30;
For example, the upper lid has a substantially rectangular shape, and has an inner chamber 2 that can accommodate a key head 31 inside, and a notch 3 in the center of the bottom for forming a key insertion hole 35, which will be described later.
Further, a pair of recesses 4 are provided on both sides of the key insertion hole 35. A recessed groove 5 serving as a decoration is provided on the front side of the upper cover excluding the bottom part, and in the middle part of both sides. Furthermore, a projection 6 is provided at the center of the front surface of the upper lid 1.

Reference numeral 8 designates a lower lid formed in the same shape as the upper lid 1, and has an inner chamber 19 that pairs with the inner chamber 2 inside, and a pair of protrusions 9 provided at the bottom engage with the recess 4 to insert the pin 10. The bottom parts of the upper cover 1 and the lower cover 8 are rotatably connected to form a key chain 11 which can be opened and closed. A screw punch 13 having a recess 12 on the upper surface for accommodating the protrusion 6 is fixed to the front surface of the lower lid 8, and a rotating body 14 is rotatably screwed onto the screw punch. 1
3, and then the tip of the threaded punch is pushed outward to prevent the rotating body 14 from slipping out. The notch 15 provided at the bottom of the lower cover 8 and the notch 3 provided in the upper cover 1 are aligned to form a key insertion hole 35, and the head 31 of the key 30 is inserted inside the upper and lower covers. A storage chamber 20 is provided for accommodating.

Note that a flexible material 16 such as urethane may be attached to the inner surfaces of the upper lid 1 and the lower lid 8, respectively, if necessary. In addition, the shape of the key chain is the head of the key 31.
The outer shape does not necessarily have to be the same as the outer shape of the key, as long as the key head can be accommodated without moving. In addition, protrusions 18 with an appropriate uneven pattern are formed on the front and back surfaces of the holder so that the key holder 11 is held in the hand and does not slip when the key holder is rotated. or,
19 is provided with recessed grooves 21 in the intermediate portions of both side surfaces and the front surface of the lower lid 8 excluding the bottom, so that the mating portion of the upper lid and the lower lid cannot be seen at first glance.

Next, to explain the operation of this embodiment, the rotating body 14 is rotated and moved to the tip side of the screw punch 13, and then the upper cover 1 is pivoted upward by holding the protrusion 6, and the storage chamber 20 is Open the key 30 to protrude from the storage chamber side to the outside of the key insertion hole 35, and then align the upper cover 1 and the lower cover 8, and then rotate the rotating body 14 to fix the protrusion 6 in the recess 12. to secure the top and bottom lids.

Accessories 39 such as a decorative chain 38 and a pendant 37 can be connected to this rotating body 14.

"Effects of the invention" This invention has the following effects.

(1) Since it is attached to the head of the key, the head of the key, which always sticks out inside the car, can be decorated and made smarter.

(2) Since the head of the key is covered and decorated and the key can be connected to the holder, it is possible to prevent the key from being lost and the key is easy to handle.

(3) By covering the head of the key, the area of the operating part of the key is expanded, making it easier to apply force, thereby making it possible to perform the operation when starting the engine reliably and easily.
