Description

  The present invention relates to a doorknob cover that is attached to a doorknob to assist in the rotation of the doorknob when the door is opened and closed. In particular, it can be easily installed by a powerless person such as an elderly person, and is replaced with a new one that is inexpensive. The object is to provide a rubber cover for a door knob that can be used and is always clean.

Conventionally, many means for attaching a cover such as a slip stopper to the door knob have been proposed. For example, a door knob cover for slip prevention described in Patent Document 1 has been proposed in which an uneven slip stopper is formed on the surface of the cover. Further, the door handle protective cover described in Patent Document 2 is provided with a buffer by winding the end of the cylindrical cover. Further, the door knob cover of Patent Document 3 is provided with a pile ground on the base surface of rubber or the like. And in the Example of the handle for doors described in patent document 4, what has a several ditch | groove and protrusion on the outer peripheral surface of a cover is described.

  However, even though these conventional door knob covers have the same purpose of assisting the rotation operation of the door knob, many problems remain in practical use.

  For example, there are a plurality of protrusions on the outer peripheral surface of the elastic cover described in the embodiment of Patent Document 4 or the one provided with an uneven slip stopper on the surface portion of the elastic cover, such as the door knob cover of Patent Document 1. However, the elastic cover has to be thick due to the uneven slip stoppers and the plurality of protrusions. If it does so, big power will be needed when opening a cover and attaching it to a doorknob, and there was a possibility that attachment of a cover might become difficult for a weak person, such as an elderly person.

  In addition, if the surface of the elastic material is provided with uneven slip stoppers, a plurality of protrusions, etc., the manufacturing process for providing these slip stoppers is complicated, and there is a disadvantage that the manufacturing cost of the cover is increased. In particular, since many hands come into contact with the cover attached to the door knob, clean management is always desired. Therefore, it is preferable to clean the door knob cover as often as possible or replace it with a new one. However, if the door knob cover is expensive and expensive to manufacture, the frequency of replacement is lower than that of an inexpensive door knob cover, which causes sanitary problems. In addition, the protrusions and grooves formed on the surface of the elastic material prevent the door knob cover from being cleaned, making clean management difficult.

  On the other hand, the handle protective cover described in Patent Document 2 is provided so as to protect the door knob and the nearby wall during construction work. For this reason, the cover itself of Patent Document 2 is intended to protect the doorknob, and does not actively assist the rotation operation of the doorknob for a powerless person as in the present invention.

  In addition, a cover in which a pile ground is integrally provided on the surface of a base such as a rubber like the door knob cover described in Patent Document 3 increases the manufacturing cost of the cover, and the anti-slip of the pile ground tends to become dirty, and cleaning. Therefore, it is not suitable as a material to be attached to a door knob that requires clean management.

  Further, as in the embodiment described in Patent Document 4, in a cover in which a plurality of concave grooves are provided on the outer peripheral surface of the elastic cover, the concave grooves are thinner than other portions of the cover. It has been clarified by experiments of the present inventors that when the elastic cover is partly thin, it is easy to break from the thin part of the cover when the cover is attached to the door knob.

  As described above, many elastic covers to be attached to the doorknob have been proposed. However, if the cover surface is provided with uneven projections, the cover becomes thick and it is difficult to attach or replace the cover. If it becomes impossible to provide an inexpensive product to form such protrusions, replacement with new ones will be reduced, and the protrusions and grooves will prevent the cover from being cleaned, resulting in sanitary problems, and for slip prevention Providing a concave groove on the door has many problems in putting the door knob cover into practical use, such as being easily broken from the thinned concave groove.

  Therefore, the present invention has been devised to solve the above-mentioned problems, and has a sufficient anti-slip effect without providing an anti-slip material that makes the elastic cover thicker or thinner, and is durable. The purpose is to provide an extremely practical doorknob cover that is easy to use and replaceable even by a weak person, is easy to clean, and can be used hygienically at low cost. It is what.

  The first means of the present invention is to cover the door knob P with a plurality of locking holes 2 in the peripheral side surface of the cover 1 in the cover 1 made of a cylindrical elastic material to be mounted on the surface of the door knob P. 1 is provided so that a finger touches the locking hole 2 that is elastically deformed when the 1 is mounted.

  The second means is a cylindrical elastic cover 1 mounted on the surface of the door knob P. A plurality of locking holes 2 are opened on the peripheral side surface of the cover 1. The cover 1 is opened at equal intervals along the center of the width of the cover 1 and is provided so that a finger touches the locking hole 2 that is elastically deformed when the cover 1 is attached to the door knob P.

  The third means is to open a plurality of locking holes 2 on the peripheral side surface of the cover 1 in the cylindrical elastic cover 1 attached to the surface of the door knob P. The cover 1 is opened at equal intervals along the center of the width of the cover 1 and is opened in a circular shape with a diameter of 8 mm to 12 mm with respect to the cover 1 having a width of 30 mm to 40 mm. It is provided so that a finger touches the locking hole 2 that is elastically deformed when the is attached.

  The fourth means is a cylindrical elastic cover 1 attached to the surface of the doorknob P. A circular shape having a diameter of 8 mm to 12 mm on the peripheral side surface of the cover 1 having a thickness of 1 mm to 2 mm and a width of 30 mm to 40 mm. A plurality of the locking holes 2 are opened, and four to eight locking holes 2 are opened at equal intervals along the center of the width of the cover 1, and the cover 1 is attached to the door knob P. It is a means for solving the problem that the finger is brought into contact with the locking hole 2 that is elastically deformed when it is pressed.

  As described in claim 1 of the present invention, a plurality of locking holes 2 are formed in the peripheral side surface of the cylindrical elastic cover 1, so that the surface of the elastic cover is thickened by uneven projections or the like. Even if it does not provide the structure which becomes thin, or the structure which becomes thin, such as a ditch | groove, it has sufficient anti-slipping effect. In addition, problems such as the early breakage of the elastic cover from the thinned part, such as a conventional groove provided for preventing slipping, are eliminated, and the durability of the cover 1 can be maintained.

  In addition, since a plurality of locking holes 2 are formed in the peripheral side surface of the cover 1 made of a cylindrical elastic material, it is extremely simple compared to an elastic cover provided with uneven protrusions, grooves or the like. In addition, the structure is easy to clean. Therefore, hygienic management is possible by cleaning the cover 1. In addition, since the manufacturing process can be reduced, an inexpensive provision is possible. As a result, even if the cover 1 is dirty, the cover 1 can be replaced with a new cover 1, which is very hygienic.

  Further, by providing the finger so as to touch the locking hole 2 that is elastically deformed when the cover 1 is attached to the door knob P, when the finger is applied to the locking hole 2 at the time of extension, the locking hole 2 passes through the locking hole 2. Thus, the rotational force of the fingers is efficiently transmitted to the entire cover 1. Assuming that the door knob P is operated after the fingers are locked in the locking holes 2 that are not elastically deformed, the operating force of the fingers is transmitted to the cover 1 after extending the locking holes 2 once. Therefore, the transmission of the operation is delayed as compared with the locking hole 2 that has already been extended by elastic deformation. Therefore, since the locking hole 2 is elastically deformed at the time of mounting, the rotation operation of the door knob P is efficiently assisted, and even a weak person such as an elderly person can easily operate the door knob P. . In addition, since the cover 1 and the locking hole 2 at the time of mounting are extended, they overlap the surface of the door knob P exactly. As a result, not only a weak person but also a healthy person does not feel uncomfortable when holding the door knob P.

  According to the second aspect of the present invention, the locking hole 2 can widen the elastic allowable range of the cover 1 by opening the locking hole 2 at equal intervals along the center position of the width of the cover 1. As a result, the problem that the elastic tolerance range is restricted and mounting work and replacement work become difficult, such as a thick elastic cover provided with uneven projections on the cover surface, is solved, even for the weak It is easy to handle and can be easily installed and replaced by one person. Therefore, for example, an elderly person living alone can freely use the door knob P at home. Further, by disposing the locking hole 2 at the center of the width, when the cover 1 is elastically deformed, the elastic force at both ends of the width becomes stronger than that at the center. As a result, when attached to the door knob P, both ends of the width of the cover 1 can be firmly attached to prevent the cover 1 from being displaced. For this reason, even if the doorknob P is operated by a hand wearing a glove, a rubber glove, or a hand to which water or soapy water adheres, the rotation operation can be efficiently assisted without slipping. Even when the door is opened with a hand wet with soap or the like during bathing, it can be opened very easily.

  According to a third aspect of the present invention, the locking holes 2 are opened at equal intervals along the center of the width of the cover 1 and open in a circular shape with a diameter of 8 mm to 12 mm in the cover 1 with a width of 30 mm to 40 mm. It is easy to attach to the door knob P used in ordinary houses, etc., and the door knob P can be rotated with the locking hole 2 deformed at the time of mounting. Demonstrates a firm grip to assist. Moreover, since the circular locking hole 2 is configured so that stress is not concentrated on a part of the cover 1 even when the cover 1 is elastically deformed, the circular locking hole 2 can be used as an elastic cover that is partially thin like a conventional groove. Compared to durability. Moreover, since the cover 1 covers the operation part of the door knob P, unpleasant feelings due to static electricity can be prevented.

  According to claim 4, a circular locking hole 2 having a diameter of 8 mm to 12 mm for locking a finger on the peripheral side surface of the cover 1 having a thickness of 1 mm to 2 mm and a width of 30 mm to 40 mm is opened. Four to eight stop holes 2 are opened at equal intervals along the center position of the width of the cover 1 so that the locking holes 2 function at any position of the cover 1 to rotate the door knob P. Can assist. In addition, by using the cover 1 of this size, it is possible to use a wide ring-shaped rubber or the like for manufacturing a rubber band or the like for the cover 1, and it can be provided at a very low cost. Therefore, it becomes possible to use the sanitary cover 1 more quickly by replacing the dirty cover 1 earlier.

  As described above, according to the present invention, it has a sufficient anti-slip effect without providing an anti-slip material that makes the elastic cover thicker or thinner, and is excellent in durability, and even a weak person can apply to the door knob. It has various beneficial effects such as easy mounting and replacement, easy cleaning, and hygienic use by providing low cost.

  The best mode of the present invention is to lock a finger on the peripheral side surface of the cover 1 having a thickness of 1 mm to 2 mm and a width of 30 mm to 40 mm in a cylindrical rubber cover 1 attached to the surface of the door knob P. A plurality of circular locking holes 2 having a diameter of 8 to 12 mm are opened. Four to eight locking holes 2 are opened at equal intervals along the center of the width of the cover 1. The original purpose is achieved by providing the finger so as to touch the locking hole 2 which is elastically deformed when the cover 1 is attached to the door knob P.

  The configuration of the present invention includes a cover 1 made of an elastic material having a cylindrical shape, and a plurality of locking holes 2 opened on the peripheral side surface of the cover 1.

  The cover 1 is a member attached to the surface of the door knob P, and is formed in a cylindrical shape with an elastic material such as natural rubber or synthetic rubber. This cylindrical shape is a shape that is attached to the surface of the circular door knob P, and the cover 1 is forcibly expanded and attached to the door knob P using the elastic force of the cover 1.

  A plurality of locking holes 2 are opened on the peripheral side surface of the cover 1 (see FIG. 1). When the cover 1 is attached to the door knob P, the locking hole 2 is also elastically deformed with the elastic deformation of the cover 1 (see FIG. 2). That is, when the cover 1 is attached to the door knob P, the locking hole 2 is wider than the original shape, and is easily locked to a finger having the door knob P.

  Moreover, the elastically deformed locking hole 2 is in a state where tension is applied to the locking hole 2 as the cover 1 is extended. When a finger is applied to the locking hole 2 in this state, the rotational force of the finger is transmitted to the entire cover 1 through the locking hole 2.

  The locking holes 2 are opened at equal intervals along the center position of the width of the cover 1 (see FIG. 1). By disposing the locking hole 2 at the center of the width, when the cover 1 is elastically deformed, the elastic force at both ends of the width becomes stronger than that at the center. As a result, when attached to the door knob P, both ends of the width of the cover 1 are firmly attached to prevent the cover 1 from being displaced.

  The locking hole 2 in the illustrated example shows a state where the cover 1 having a width of 30 mm to 40 mm is opened in a circular shape having a diameter of 8 mm to 12 mm. By setting the width of the cover 1 to 30 mm to 40 mm, the size is most suitable for mounting on a general circular door knob P. That is, the cover 1 does not need to cover the entire surface of the door knob P, and when the door knob P is operated to rotate, the cover 1 can achieve the purpose sufficiently by being attached only to a portion that is gripped by fingers. Therefore, by setting the width of the cover 1 to 30 mm to 40 mm, it is possible to cover the area necessary for the rotation operation of the door knob P (see FIG. 2). Further, by setting the size of the cover 1 in this way, it is possible to use a wide ring-shaped rubber or the like for manufacturing a rubber band or the like. Then, it becomes possible to provide an extremely low price, and even when the cover 1 is dirty, it can be easily replaced with a new one, so that clean use is always possible. On the other hand, the diameter of the cover 1 changes depending on the elastic force of the cover 1, but according to the experiment of the inventor, four locking holes 2 are opened in the natural rubber cover 1 having a width of 30 mm and a thickness of 1 mm. In the case of the pierced one, a diameter of around 40 mm was suitable for the mounting work.

  On the other hand, the reason why the locking hole 2 is set in a circular shape having a diameter of 8 mm to 12 mm is a result of paying attention to the mountability of the cover 1. That is, when a cover 1 having a width of 30 mm is used, it has been proved by experiments that the cover 1 is difficult to extend when the diameter is about 5 mm, and that the cover 1 is excessively extended when the diameter is 15 mm. In this experiment, four locking holes 2 were opened at equal intervals along the center of the width of the cover 1 (see FIG. 3). Further, as the number of the locking holes 2 increases, the elastic allowable range of the cover 1 tends to expand. However, when the locking hole 2 of about 10 mm is opened in the center of the cover 1 having a width of about 30 mm, Even if the number of the locking holes 2 is increased, there is little influence on the elastic force at both ends of the width of the cover 1 because the locking holes 2 are arranged at the center of the width. Accordingly, the number of the locking holes 2 is suitably about 4 to 8.

  Further, by arranging the four to eight locking holes 2 at equal intervals, the locking holes 2 at the time of mounting are arranged around the door knob P (see FIG. 4). If it does so, it will be in the position where a part of finger always locks in the elastically deformed locking hole 2.

  FIG. 3 is a development view of the cover 1, but as a manufacturing means of the cover 1, it can be formed in a cylindrical shape in which a band-shaped elastic body is joined.

  In addition, each structure of the example of illustration in this invention is only one Example of this invention, and the design change of a shape, a dimension, a change of material, a shape change, etc. are free in the range which does not deviate from the summary of this invention. It can be done.
