Description

The present invention relates to a kind of protective cover for a door handle, particularly, a protective cover made of elastic silicone rubber.

Generally, the door knob of many door handles is metal-pressed and has a smooth outer surface so as to beautify its outer surface, so that it provides a good tactile feel when gripping the knob with a hand.

However, the knob on the door handle described above has a smooth surface when the hand is wet, especially when bathing in the bathroom or when water is left on some of the hands after washing the hands in the toilet. , A slip occurs between the hand and the knob, and it becomes difficult to open the door. In addition, most knobs are varnished or electroplated to improve the appearance and texture, but these two types can improve the appearance but do not scratch. The varnish or the electroplated layer may be peeled off when used for a certain period of time, and the appearance of the varnish or the electroplated layer may be affected, and in such areas, climatic factors may easily cause static electricity to disturb people. In addition, generally known knobs or handle levers of door handles do not have a function of being able to discriminate even when it is necessary to open the door urgently at the time of a sudden power failure or a power failure due to an unexpected incident, even in the dark. Therefore, the present invention provides a protective cover for a door handle which solves such disadvantages of the conventional door handle.

According to a first aspect of the present invention, there is provided a protective cover for a door handle, wherein the protective cover is formed of elastic silicone rubber and has front and rear openings, a knob of the door handle is inserted through a rear opening, and the protective cover is secured to the outside of the knob. And a protective function is achieved, a plurality of anti-slip protuberances are arranged on the outer surface of the protective cover to prevent slippage when the knob is gripped and turned by hand, and at least an inner annular surface of the protective cover is provided. The present invention provides a protective cover for a door handle, wherein the protective cover is provided with an annular groove around the circumference and tightly engages with the knob with good elasticity when the protective cover is mounted on a knob having a different curved surface.
According to a second aspect of the present invention, there is provided the protective cover for a door handle according to the first aspect, wherein the protective cover has a decorative line design with decorativeness on a rim of a front opening of the protective cover, and an overall appearance of a combination of the protective cover and the knob. Protective cover for door handle, characterized by improved
According to a third aspect of the present invention, in the protective cover for a door handle according to the first aspect, a fluorescent substance is added to the silicone rubber material in a specific area of the annular area at both ends of the protective cover to form two annular fluorescent bands. The protective cover of the door handle is characterized in that the protective cover is formed, and in the dark without light rays, the position of the knob of the door handle is notified by the fluorescent light generated by the annular fluorescent band at the front and rear opening edges. .
According to a fourth aspect of the present invention, there is provided the door handle protective cover according to the first aspect, wherein the protective cover is formed in a shape applicable to a knob or a handle lever of the door handle. .

The protective cover of the door handle of the present invention is made of elastic silicone rubber and has front and rear openings, and the knob of the door handle is inserted from the rear opening to be tightly fitted to the protective cover and the outside of the knob to form a protective function. A plurality of anti-slip protuberances are provided on the outer surface of the protective cover to prevent slippage when gripping and turning the knob by hand, provide a good tactile feeling when turning the knob, do not generate a cold sensation, and generate static electricity. There is a decorative line design on the rim of the front opening of the protective cover to prevent and improve the overall appearance of the combination of the protective cover and the knob, and a silicone rubber material in a specific area area of the rim of the opening before and after the protective cover In the case where the fluorescent substance is contained in the protective cover, even if it is dark, the annular fluorescent band generated from the front and rear opening edges informs the knob position, and at least one annular groove is provided on the inner annular surface of the protective cover and the protective cover is Knob and 緊合 with good stretchability when being 套設 a curved knob made.

As shown in FIGS. 1, 2, and 3, the protective cover 1 of the door handle of the present invention is formed of elastic silicone rubber. The protective cover 1 has a front opening 12 and a rear opening 11, and the knob of the door handle 2 is provided. 21 is inserted through the rear opening 11, the protective cover 1 is tightened outside the knob 21, and achieves the protective function. A plurality of anti-slip protruding patterns 13 are provided on the outer surface of the protective cover 1 to prevent slippage when the knob 21 of the door handle 2 is gripped and turned by hand, and to provide a good tactile sensation when turning the knob 21. Provides no cold sensation as well as preventing static electricity. In addition, a decorative streak 12 design with decorativeness is provided at the rim of the front opening 12 of the protective cover 1, thereby improving the overall appearance of the combination of the protective cover 1 and the knob 21. In addition, a fluorescent substance is added to the silicone rubber material in a specific area of the annular area of the front opening 12 and the rear opening 11 of the protective cover 1 so that two annular fluorescent bands 15 are formed. Even in the dark where the protective cover 1 has no light, the position of the knob 21 can be notified by the annular fluorescent light generated by the fluorescent bands 15 at the front and rear opening edges. In addition, at least one annular groove 14 is provided on the inner annular surface of the protective cover 1 so that when the protective cover 1 is mounted on the knob 31 having a different curved surface, an effect of engaging with the knob 31 with good elasticity is achieved. (See FIGS. 4 and 5).

防 The protective cover 1 of the present invention can be formed in a required form by the handle shape of various door handles. In addition to the above-described annular cover-shaped protective cover 1, when used for a door handle 4 having a handle lever 41, it is a long tubular protective cover 5 having a fitting hole 51 at the center. It is installed to achieve the protection function. A plurality of anti-slip protruding patterns 53 are provided on the outer surface of the protective cover 5 to prevent slipping when the handle lever 41 of the door handle 4 is gripped and turned by hand, and is good when the handle lever 41 is turned. Provides a soft touch and does not generate a cold sensation. At one end or both ends of the protective cover 5, a decorative streak 52 design with decorativeness is provided, thereby improving the overall appearance of the combination of the protective cover 5 and the handle lever 41 (FIGS. 6 and 7). reference). The protective cover 5 is also applied to a door handle 6 having a curved handle lever 61 (see FIGS. 8 and 9). In addition, a fluorescent substance is added to the silicone rubber material in a specific area of the annular area at both ends of the protective cover 5, thereby forming two annular fluorescent bands 55. However, the positions of the handle levers 41 and the curved handle levers 61 of the door handles 4 and 6 can be notified by the annular fluorescent light generated by the two annular fluorescent bands 55.
