Abstract

PROBLEM TO BE SOLVED: To make easy to turn a doorknob by inserting a cover composed of a flexible material onto the doorknob. SOLUTION: By inserting a cover 1 made up of a flexible material onto a doorknob, grip is given. Combining the front of the cover 1 with a stopper and a surface portion 3 with irregularities 5, a grid groove and a material having a high friction factor makes the doorknob turnable by a small force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a doorknob cover that facilitates rotation of a doorknob by inserting a cover made of an elastic material into the doorknob.

[0002]

2. Description of the Related Art Conventionally, a door knob has been polished at a portion to be gripped by a hand, and has been smooth.

[0003]

This has the following disadvantages. I. Since the part to be gripped by the hand was slippery, the hand slipped for those with wet hands and those with gloves, making it difficult to turn the door knob. B. Since it does not rotate unless it is turned with a certain force or more, opening and closing the door is inconvenient for the elderly, those with hand disabilities, and those who have their hands injured. The present invention has been made to solve these disadvantages.

[0004]

An uneven slip stopper is formed on a surface portion (3) of a cover (1) formed of a resilient material into a substantially cylindrical shape. Insert the hollow part (2) inside the cover (1) into the door knob. The present invention is a doorknob cover for preventing slippage that facilitates rotation of the doorknob as described above.

[0005]

Embodiments of the present invention will be described below. I. A hollow portion (2) conforming to the shape of a doorknob to be inserted is formed in a cover (1) made of a material having elasticity and having a substantially cylindrical shape having the same shape as the doorknob. B. When inserted, a stopper (4) is formed on the front part of the cover (1) that comes into contact with the keyhole of the door knob. C. On the surface portion (3), unevenness (5), lattice-shaped grooves (6) and non-slip of a material (7) having a high coefficient of friction are formed. The present invention has the above configuration. When using the present invention, the hollow part (2) is inserted into the door knob and the door knob is rotated. Since the present invention is made of a resilient material, when the door knob is rotated, the grip force is increased, and the rotation of the door knob is facilitated with a small force.

[0006]

Embodiments of the present invention will be described below. I. An elastic material is used as a material forming the door knob cover. What is an elastic material?
(A) rubber, (B) silicone, (C) plastic,
(D) styrene resin, (e) urethane, (f) vinyl chloride, (g) polypropylene, (h) polyethylene,
(Ri) Nylon, (Nu) cellulose. B. As shown in FIG. 2, by attaching a stopper (4) that covers a part of the surface of the door knob with the keyhole, it is possible to prevent the stopper (4) from shifting in the vertical direction. C. Since a material having elasticity is used, it can be easily processed into a rounded shape according to the shape of the doorknob. D. As shown in FIG. 5, in order to further increase the gripping force, a shape is used in which a material (7) having a high friction coefficient different from that of the surface portion (3) is combined. Materials with a high coefficient of friction are (a) rubber, (b) silicone, (c) plastic, (d) styrene resin,
(D) Urethane, (e) vinyl chloride, (f) polypropylene, (g) polyethylene, (h) nylon, (li)
Cellulose and (nu) metal powder, (le) carbon,
(ヲ) Glass, (W) glass fiber, (G) ceramic, (Y) other hard substances.

[0007]

When the doorknob cover shown in the drawing is inserted into the doorknob, the gripping force is increased, so that the elderly, the handicapped, the gloved, the wetted, etc. For some reason, if you have difficulty opening and closing the door because you do not have enough force to turn the doorknob in your hand, you can easily turn the doorknob and open and close the door smoothly . Since the material of the present invention uses an elastic material, the following effects can be obtained. I. Since the doorknob cover is inserted into the doorknob as shown in the drawing due to its high elasticity, this is facilitated. B. When a force is applied to rotate after mounting, since the airtightness is high, there is an effect of preventing displacement due to sliding with the door knob. C. Even when a part of the body hits, the safety ratio is high because it absorbs impact. In addition, the surface portion (3) of the cover (1) is provided with an uneven body (5) and a retaining groove (6) which are easily applied to a finger, and an elastic material constituting the surface portion (3). By combining a material (7) with a high coefficient of friction different from
Grip power can be further increased. Furthermore, since the doorknob cover is made of a resilient material, antibacterial specifications are possible.
Also effective in hygiene.

Claims (1)

[Claims] A cover (1) made of a resilient material and formed in a substantially cylindrical shape is provided with an uneven anti-slip surface portion (3), and a hollow portion (2) is inserted into a door knob. The doorknob cover for non-slip which makes the doorknob easy to rotate.
