Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device related to opening and closing by a lever knob of an entrance door or the like, and more particularly, to a support that does not rotate a door lever knob.

[0002]

[Prior art]

 Conventionally, as this type of door opening stop device and door guard, use of a method of connecting a door to a door frame with a chain or an iron workpiece is known.

[0003]

[Problems to be solved by the invention]

 The device described in the prior art is set on the door and door frame in advance, and there are cases where the secondary lock such as a chain is easily cut off when unlocked from the outside.

[0004] Tertiary retrofitting is also well known, but sometimes requires installation work, and requires bolt holes for installation on the door. In the case of rental housing, etc., there is a problem because the principle is to return to the current situation.

[0005] The present invention has been made in view of the above-mentioned problems of the conventional technology, and has as its object the purpose of making it difficult to easily remove it without performing installation work, and to surely mount the support. An object of the present invention is to provide an unlocking / stopping support that is not only inconspicuous but also excellent in appearance, as well as in a room.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the lever knob rotation stop support in the present invention has a substantially round cylindrical shape, a U-shaped door lever knob receiver is provided at the tip, and the cylindrical pipe is a slide type. A fixed body was provided to fix the slide at the required position. A spring is attached to the lower part of the slide tubular pipe, and a rubber support is attached to the lower floor contact surface.

[0007] A cushion rubber, which is an elastic body, is provided on the inner surface of the U-shaped door lever knob receiving portion at the front end so that the lever knob does not slip and slip.

In this door lever knob rotation stop support, a support whose height has been adjusted in advance from under the lever knob is mounted using a spring force to lift the lever knob.

Thus, even if the door can be unlocked from the outside, the door lever knob is not rotated by the support to the door opening position, thereby preventing entry from outside.

[0010]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. In FIG. 1, the adjusting slide bar (1) of the support is formed in a cylindrical shape having a thickness of about 1 mm to 2 mm by extrusion molding using, for example, resin plastic. The adjustment slide rod (1) is formed in a cylindrical shape having a thickness of about 0.5 mm to 1 mm by extrusion molding using aluminum metal. A slide fixing body (2) is provided so as to fix the adjustment slide bar (1) at a required position, and the adjustment slide bar (1) can be fixed and released.

The upper portion of the support is provided with a lever knob receiving portion (3), which is a U-shaped concave portion, and a cushion rubber (4) is provided at the tip of the concave portion to prevent slippage or displacement from the door lever knob (7). I did it.

A floor ground rubber (6) is provided on the floor ground surface of the adjustment slide bar (1) below the support, and a cushion spring (5) is mounted therebetween. The cushion spring (5) becomes a spring when the support is attached to the door lever knob (7) and is easy to attach. Since the support is always lifted after installation, it can be rotated from outside to open the door. As shown in Fig. 3, since the attached support has good adhesion, the door can be prevented from opening by turning the door lever knob from the outside.

[0013]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

In the support device of the first aspect, a U-shaped door lever knob receiver is provided at an upper portion, and an elastic cushion rubber is stuck to the inside of the U-shaped member so that the door lever knob is not damaged. At the same time, it does not come off or slip off from the doorknob when installed.

[0015] The support according to the second aspect is a main body part, which has a substantially round cylindrical shape, and is configured to slide in two steps, three steps, or four steps as required. The adjustment slide bar was provided with a slide fixing body for fixing the slide at a required position. As a result, the door lever knob can be easily fixed even if the height position is different, and it can be downsized and lightweight and beautiful when the support is stored.

Rubber is provided below the support of claim 3 to protect the ground contact surface, and a cushion spring is mounted thereon to be connected to the main body support. When attaching the support to the door lever knob, the door lever knob can be easily attached by lifting the door lever knob by using the force of the spring, and the unlocking from the outside can be reliably stopped.
