  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature and is not intended to limit the present invention, its application, or its use.

  FIG. 1 shows a grip cover 1 according to an embodiment of the present invention. As shown in FIG. 2, the grip cover 1 is used by being attached to a grip portion 3a of a columnar handrail 3 extending in the vertical direction, for example. In addition, as a material of the handrail 3, any of a metal, wood, resin, etc. may be sufficient.

  As shown in FIGS. 3 to 7, the grip cover 1 includes a cylindrical tubular portion 10 made of an elastically deformable material. Examples of the material constituting the cylindrical portion 10 include resin materials such as polypropylene, hard elastomers, and rubbers. When the material constituting the tubular portion 10 is rubber or elastomer, the hardness thereof is preferably set in the range of 20 to 97 in terms of Shore hardness A. In addition, when the material which comprises the cylindrical part 10 is made into a resin material, it is preferable to set the hardness in the range of 40 or more and 120 or less by the Rockwell hardness R scale.

  The length of the cylindrical portion 10 in the center line direction is longer than the width of a general human palm, and is set to about 200 mm, for example. The inner diameter of the cylindrical portion 10 is set slightly smaller than the outer diameter of the grip portion 3a. Moreover, the inner peripheral surface of the cylindrical part 10 is comprised by the smooth curved surface so that it may extend along the outer peripheral surface of the grip part 3a. Therefore, when the grip cover 1 is attached to the grip portion 3a, substantially the entire inner peripheral surface of the tubular portion 10 is in close contact with the outer peripheral surface of the grip portion 3a.

  As shown in FIG. 1, the cylindrical portion 10 is formed with cuts 11 extending in the center line direction across both ends. The cut line 11 extends linearly along the center line of the tubular portion 10. By providing the cut 11, the cylindrical portion 10 can be opened so as to expand from the cut 11, as indicated by a virtual line in FIG. 5.

  One end side in the longitudinal direction of the cut line 11 (left side in FIG. 1) is an enlarged portion 11a that is set so that the width gradually increases as it approaches one end (left end) in the longitudinal direction of the tubular portion 10. The width of one end in the longitudinal direction of the enlarged portion 11a of the cut 11 is set to 10 mm or more and 20 mm or less. The width of the cut line 11 other than the enlarged portion 11a is set to be 1 mm or less when the grip cover 1 is attached to the grip portion 3a. Thereby, it becomes difficult to see the grip part 3a from the cut line 11, and the appearance is improved. The width of the cut line 11 is preferably 0.6 mm or less.

  At both ends in the center line direction of the outer peripheral surface of the cylindrical portion 11, ridge portions 12, 12 that protrude radially outward and extend in the circumferential direction are provided. These protrusion parts 12 and 12 are made into the same shape, and the protrusion direction front end surface of the protrusion parts 12 and 12 is comprised by the curved surface.

  Further, a corrugated portion (slip prevention portion) 13 that is continuous in the center line direction is provided between the two ridge portions 12, 12 on the outer peripheral surface of the tubular portion 10. The top portion 13 a of the wave shape portion 13 is configured by a curved surface that is curved outward in the radial direction of the tubular portion 10. The outer diameter of the portion of the tubular portion 10 where the top portion 13a is formed is set to be substantially the same as the outer diameter of the portion where the protrusion 12 is formed. The space | interval of the adjacent top parts 13a and 13a of the waveform-shaped part 13 is set to 10 mm or more and 30 mm or less.

  Further, the bottom portion 13 b located between the adjacent top portions 13 a and 13 a of the corrugated shape portion 13 is configured by a curved surface that is curved inward in the radial direction of the tubular portion 10. The bottom portion 13b is smoothly connected to the adjacent top portions 13a and 13a, and a recess by the bottom portion 13b is formed on the outer peripheral surface of the tubular portion 10 so as to extend in the circumferential direction. Moreover, as shown in FIG. 4, the thickness of the site | part corresponding to the bottom part 13b in the cylindrical part 10 is thinner than the thickness of the site | part corresponding to the top part 13a.

  Next, a procedure for attaching the grip cover 1 configured as described above to the grip portion 3a of the handrail 3 will be described. First, a force is applied to the tubular portion 10 so that the tubular portion 10 expands from the cut 11 portion. Then, as shown in FIG. 5, the cylindrical part 10 is elastically deformed and opened. At this time, since the hardness of the material of the cylindrical portion 10 is 97 or less in Shore hardness A or 120 or less in Rockwell hardness R scale, it can be sufficiently deformed.

  Next, the grip portion 3 a is inserted into the cylindrical portion 10 from the opened portion. At this time, the site | part corresponding to the enlarged part 11a of the cut | interruption 11 is opened more largely than another site | part, and workability | operativity improves by putting the grip part 3a from this enlarged part 11a. After that, the shape of the cylindrical portion 10 is restored by removing the force applied to the cylindrical portion 10. Thereby, the grip cover 1 is attached to the grip part 3a. In this attached state, since the hardness of the material of the cylindrical portion 10 is 20 or more in Shore hardness A, the shape is maintained and it is difficult to come off from the grip portion 3a.

  Next, a case where the user grips and uses the cylindrical portion 10 of the grip cover 1 will be described. When the user grips the grip cover 1, the finger fits between the adjacent top portions 13 a and 13 a in the wave shape portion 13. At this time, since the interval between the adjacent top portions 13a and 13a of the corrugated shape portion 13 is 10 mm or more and 30 mm or less, a general user's finger is securely fitted between the adjacent top portions 13a and 13a. Hands are difficult to slip. Further, if the hand holding the grip cover 1 slips in the longitudinal direction of the tubular portion 10, the hand is caught by the ridge portion 12 and is difficult to come off from the tubular portion 10.

  Therefore, according to the grip cover 1 according to this embodiment, since the corrugated portion 13 is provided in the tubular portion 10, it is possible to prevent the user's hand from slipping off the tubular portion 10 and to improve safety. Can be increased.

  Further, by setting the hardness of the material of the cylindrical portion 10 in the above range, it is possible to improve the mounting workability by deforming at the time of mounting while preventing the grip cover 1 from being detached from the grip portion 3a.

  For example, as shown in FIG. 8, two grip covers 1 and 1 may be used side by side in the direction of the center line of the grip portion 3a. In this case, it arrange | positions so that the enlarged part 11a of the cut | interruption 11 of one grip cover 1 may be located in the other side of the other grip cover 1. FIG.

  Moreover, in the said embodiment, although the cylindrical part 10 is made into the single layer structure, it is not restricted to this, For example, it is good also as a multilayer structure like the modification 1 shown in FIG. In the first modification, a flexible layer 20 made of a resin material softer than the resin material is provided on the surface of the cylindrical portion 10 made of the resin material. The flexible layer 20 is soft enough to be deformed by the gripping force of the user, and is made of, for example, soft urethane paint or urethane foam. By providing the flexible layer 20, when the user grips the grip cover 1, the flexible layer 20 is deformed so as to follow the finger or palm. Thereby, the user's hand becomes more difficult to slip and the feeling of use is improved. When the flexible layer 20 is provided, the corrugated shape portion 13 may be omitted. Moreover, you may form the flexible layer 20 with rubber | gum, for example.

  In addition, as in Modification 2 shown in FIG. 10, the concavo-convex shape portion 30 formed by alternately arranging the ridge portions 30 a and the ridge portions 30 b extending in the circumferential direction on the outer peripheral surface of the cylindrical portion 10 in the center line direction. May be provided. In the third modified example, when the user's hand grips the grip cover 1, the user's hand comes along the concavo-convex shape portion 30, and is difficult to slip.

  Moreover, you may make it affix the antiskid member (slip prevention part) 25 which consists of rubber | gum etc. to the internal peripheral surface of the cylindrical part 10 like the modification 3 shown in FIG. The anti-slip member 25 makes it difficult for the tubular portion 10 to slide with respect to the grip portion 3a, and prevents the grip cover 1 from being displaced. The anti-slip member 25 can be composed of an adhesive tape or the like other than rubber. Further, instead of the anti-slip member 25, an anti-slip portion may be configured by applying an adhesive to the inner peripheral surface of the tubular portion 10.

  Moreover, as in Modification 4 shown in FIG. 12, the resin material may be changed between the longitudinal intermediate portion 10a of the cylindrical portion 10 and the end portions 10b and 10b, and these may be integrated. In the modified example 4, the resin material constituting the both end portions 10b is harder than the resin material constituting the intermediate portion 10a. Thereby, the cylindrical part 10 can be firmly fixed to the grip part 3a by the both end parts 10b and 10b, and the intermediate part 10a with many opportunities for gripping by the user is relatively soft, so that the hand can be hardly slipped and used. A feeling can be made favorable.

  Moreover, the shape of the outer peripheral surface of the cylindrical part 10 is not restricted to the waveform shape part 13 or the uneven | corrugated shaped part 30, and can be set to arbitrary shapes.

  Further, as in Modification 5 shown in FIG. 13, a fastener 40 may be provided at the cut 11 portion of the tubular portion 10, and the cut 11 portion may be closed by the fastener 40. The fastener 40 includes a first fastener member 41 sewn on one edge portion of the cut line 11, a second fastener member 42 sewn on the other edge portion, and engagement pieces included in the fastener members 41 and 42. It is of a known structure provided with a slider 43 for engaging and disengaging each other. The first and second fastener members 41 and 42 are disposed inside the tubular portion 10. Therefore, when the fastener 40 is closed, the fastener members 41 and 42 and the slider 43 are difficult to see from the outside and are not easily disturbed by the person having the grip cover 1. In this modified example 5, when the grip cover 1 is attached to the handrail 3, after opening the fastener 40, the tubular portion 10 is opened so as to unfold from the portion of the cut 11, and the grip portion 3a is opened from the opened portion. Is inserted into the cylindrical portion 10 and the fastener 40 is closed, so that the grip cover 1 can be easily and reliably attached to the grip portion 3a. You may make it attach the said 1st and 2nd fastener members 41 and 42 using methods other than sewing, for example, methods, such as heat welding and adhesion | attachment, with respect to the cylindrical part 10. FIG.

  In addition, the above-mentioned embodiment is an illustration of this invention, and this invention is not limited to these examples. The material of the cylindrical portion 10 may be, for example, polyethylene or rubber. Moreover, you may make it insert in the cylindrical part 10 the grip part 3a of the handrail 3 from the longitudinal direction one end side of the cylindrical part 10, without forming the cut | interruption 11, and attach it to the grip part 3a. In addition, an uneven shape portion or a corrugated shape portion may be provided on the inner peripheral surface of the tubular portion 10.

  Moreover, if it is a prism of a grip part, what is necessary is just to form the cylindrical part 10 of the grip cover 1 in a square cylinder shape corresponding to it.

  In addition to the handrail 3 extending in the vertical direction, the grip cover 1 can be attached to each grip portion of a handrail extending horizontally, a handrail extending obliquely, or a handrail extending bent. Furthermore, the grip cover 1 can be used as long as it is an article having a grip portion in addition to the handrail.

  As described above, since the grip cover according to the present invention can prevent the hand from slipping and coming off, it is useful for handrails, for example.
