Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a key holder that can hold the key to the lock of a car, house, etc. by inserting it into the hook.

[Prior Art] In a key chain in which a large number of keys are inserted through a hook, an opening/closing element is provided at the tip of the hook in order to prevent the keys from slipping out of the hook. It opens and closes.

[Problems to be solved by the invention] In this conventional structure, most of the open/close members are always pressed by a spring in the direction of closing the tip of the hook, so when inserting the key into the hook, the key must be pressed with the tip of a finger. There was the inconvenience of having to support the opened switch to prevent it from returning to its original position.

[Means for solving the problem] This invention was devised to solve the above-mentioned problems of the conventional key chain using a hook, and its purpose is to To provide a key holder which can be moved smoothly, does not require supporting the open switch with the fingertips in that position, and can make insertion and removal of the key much easier than those of conventional structure. be.

The feature of this invention for the above purpose is that a hook and a screw shaft located opposite the tip of the hook are provided protruding from the bottom of the main body, and a gear-shaped switch is movably screwed to the screw shaft, and An operating shaft having a gear attached to the lower end thereof which meshes with the opening/closing member is rotatably installed through the opening and closing member, and a knob for rotation is provided at the upper end of the operating shaft.

[Function] In the key chain with the above structure, when the operating shaft in the center of the main body is rotated by the knob at the upper end, the gear at the lower end engages with the open/close element of the screw shaft located opposite the tip of the hook, so it can be opened and closed. The child rotates in the opposite direction to the rotation direction of the gear and moves along the screw shaft. Therefore, the switch can be closed or opened depending on the direction of rotation of the operating shaft. Further, the switch after being moved will not return to its original position unless it is stopped at that position and the operating shaft is rotated in the opposite direction.

Further, this invention will be explained in detail using illustrated examples.

In the figure, reference numeral 1 denotes a main body having an elliptical planar shape, and a hook 2 is provided on the lower side to protrude inward. A screw shaft 3 is provided above the tip of the hook 2 and is mounted on the lower side of the main body 1, and is positioned opposite to the hook 2 at a required distance.
is screwed on so that it can be moved freely.

Reference numeral 5 denotes an operation shaft rotatably installed through the center of the main body 1. A gear 6 that meshes with the switch 4 is attached to the lower end of the operating shaft, and a rotating knob 7 is attached to the upper end of the operating shaft. It is installed inside the ring 8.

Note that 9 in the figure indicates a key.

In the key chain having the above structure, when the operating shaft 5 is rotated counterclockwise while holding the knob 7, the open/close element 4 is rotated clockwise and moved to the tip of the hook.
Close the hook tip. Further, when the knob 7 is rotated in the opposite direction to the above, the opening/closing member 4 rotates the screw shaft 4 upward, thereby opening the tip of the hook. In either case, the switch stops when the operation shaft 5 stops rotating, and does not move unless the operation shaft 5 is rotated again. Furthermore, since it is meshed with the gear 6, even if the switch 4 tries to rotate by itself due to vibration or the like, the gear 6 acts as a resistance and prevents the rotation.

[Effects of the invention] As described above, this invention has the switch 4 on the side of the screw shaft 3 located opposite to the tip of the hook 2, and the gear 6 on the lower end of the operating shaft 5 penetrating through the center of the main body 1. Since they are engaged and the opening/closing element 4 is opened/closed by rotating the operation shaft 5, the opening/closing element 4 can be moved more easily than when rotating the opening/closing element directly with a fingertip. . Furthermore, since the switch stops at the position where it stops rotating and does not return to its original position, there is no need to support the switch when inserting or removing the key from the hook.

In addition, since the opener is constantly braked by gears, it is difficult to rotate even when subjected to external forces such as vibrations when carried, and the opener moves naturally, opening the tip of the hook and allowing the key to come out. It has features such as no problems.
