Key cover to protect the entire key

Abstract

This key cover prevents damage to the key blade from unintentional excessive external force during storage, prevents wear and tear on the key over time during normal handling, and prevents skimming of the number engraved on the key, which is useful for making duplicate keys. [Solution] The key cover consists of a fixed cover 1 that houses the key head and a movable cover 2 that covers the key blade. The movable cover has a rotation angle of approximately 180 degrees relative to the fixed cover, and both the fixed cover and the movable cover are made of resin material. The opening of the movable cover is narrower than the width of the tip of the key blade so that it does not easily come off the key blade, and the movable cover is made of a soft resin material, thus providing a function for attaching and detaching the movable cover.

Description

Technical Field

[0006] ,

[0001] When the key is not in use, the present invention protects the entire key. When in use, by having a rotating mechanism in the key cover, it can be removed and used without separating the cover. It relates to a key cover considering usability.

Background Art

[0002] Keys tend to be handled haphazardly when carried around normally, such as in a bag or worn on the body. Therefore, due to an unintended impact from the outside and damage to the tip, there may be problems such as the key being unable to be inserted into the keyhole or not being able to lock / unlock properly. To date, there have been proposals for covering the key head, but there has been no proposal for a key cover that protects the key blade.

[0003] For example, in Patent Document 1, the key head part is disclosed as a replaceable cover.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, with a cover only for the key head part, the most important key blade part of the key cannot be protected, so there is always a concern about problems during locking / unlocking due to damage or the like.

[0006] The problem to be solved by the present invention is to provide a key cover that covers the entire key with a resin cover to protect the key blade during normal handling of the key and allows for smooth operation during locking / unlocking. [Means for solving the problem]

[0007] This invention consists of a fixed cover that houses the key head and a movable cover that covers the key blade. The movable cover has a rotation angle of approximately 180 degrees relative to the fixed cover. When using the key, the movable cover is removed from the key blade and rotated to unlock / lock the lock. When not using the key, store the movable cover into the Keyblade. Furthermore, the problem is solved by using a key cover configuration that covers the entire key, with both the fixed and movable covers being made of resin material.

[0008] Furthermore, the opening of the movable cover is narrower than the width of the tip of the key blade to prevent it from easily coming off, and the movable part is made of a soft resin material, thereby providing a function for attaching and detaching the movable cover. [Effects of the Invention]

[0009] As mentioned above, not only is the impact resistance of the key blade improved, but by covering the entire key with a resin component, the manufacturing number engraved on the key does not appear on the surface, thus preventing skimming related to key duplication and reducing wear and tear on the keys over time and the metallic smell caused by wear particles when many keys are bundled together. Furthermore, using key covers in various colors can help prevent key loss and serve as a way to identify keys. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0011] The key cover is composed of a fixed cover for fixing the key head and a movable cover for covering the key blade, and it will be stored with both covers attached. Also, by installing a ring in the hole of the key head, the key will not come off from the key cover. The movable cover can be removed from or attached to the key blade, and the key can smoothly lock or unlock while the key cover remains integrated.

Embodiment

[0012] An embodiment will be described according to the following drawings. Figure 1 shows the overall configuration diagram. It is composed of three parts: a fixed cover 1, a movable cover 2, and a movable part pin 3.

[0013] Figure 2 shows a diagram of the key with the key cover installed. Since the fixed cover 1 is provided with a groove for inserting the key head 4a, the key head 4a is inserted into the groove. Since the movable cover 2 is provided with a groove larger than the key blade 4b, it is placed over the key blade 4b. At this time, the width 2a of this groove is made narrow so that it does not easily come off from the key blade 4b. Also, by installing a ring 5 in the hole provided on the key head 4a, the key cover will not come off from the key. This is the state for storage.

[0014] Figure 3 shows a diagram of the movable cover rotated. When using the key 4 to lock or unlock, the movable cover 2 is removed from the key blade 4b and rotated for use. After using the key 4, the movable cover is placed over the key blade for storage.

Claims

1. The key cover consists of a fixed cover that houses the key head and a movable cover that covers the key blade, with the movable cover having a rotation angle of approximately 180 degrees relative to the fixed cover. To use the key, remove the movable cover from the key blade and rotate it to unlock / lock the lock. When not using the key, store the movable cover back into the key blade. Also, the key cover is made of resin material.

2. The opening of the movable cover is narrower than the width of the tip of the key blade so that it does not easily come off the key blade, and the movable cover itself is made of a soft resin material, thus providing a key cover with a movable cover that can be attached and detached.
