Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle handle grip.

[0002]

2. Description of the Related Art Conventionally, a tubular handle grip (2) made of an elastic synthetic resin such as polyvinyl chloride is attached to a bar end portion (10) of a bicycle handlebar. The inside diameter of this handle grip (2) is the bar end (10)
Is set to be slightly smaller than the outer diameter (see FIG. 1).

The handle grip (2) is temporarily in a state where the open end of the handle grip (2) is fitted over the end of the bar end portion (10) (indicated by the chain double-dashed line in FIG. 1). (2) is forcibly pushed in and becomes in the attached state. In this attached state, since the cross section of the handle grip (2) is stretched in the circumferential direction, the friction force based on the elastic restoring force of the handle grip (2) causes the handle grip (2) to move.
Are fixed to the bar end portion (10).

[0004]

However, this conventional technique has a problem that it is difficult to fit the handle grip to the bar end portion (10). Since the handle grip (2) and the bar end part (10) are fixed to each other by frictional force, it is necessary to increase the frictional force in order to prevent the attached handle grip (2) from moving. .
For this purpose, it is necessary to increase the elastic coefficient of the handle grip (2), but when this is done, the frictional force when pushing the handle grip (2) into the bar end portion (10) also increases, and the handle grip (2) increases. Difficult to fit the grip (2).

It is an object of the inventions of claims 1 to 4 to allow the bicycle handle grip to be smoothly mounted on the bar end portion.

[0006]

The means for solving the problems of the invention according to claim 1 is "a bar end portion (10) formed of an elastic material.
It is composed of a plurality of unit cylinders (20), (20) which are tightly fitted to the handle grip mounting area. In order to attach the handle grip to the bar end portion (10), the unit cylinders (20) (20) are individually pushed from the end portion of the bar end portion (10) to a predetermined position. In this state, each unit tube (2
(0) is made of an elastic material and is closely fitted to the handle grip mounting area.
It is fixed by the frictional force acting between (10). Since the unit cylinder (20) is significantly shorter than the conventional integrated handle grip, the elastic modulus of the unit cylinder (20) is set to be large in order to increase the fixing force to the bar end portion (10). Even so, the frictional force when the unit cylinder (20) is pushed in is small. That is, the frictional force when the unit cylinders (20) are attached is small, and the movement inhibiting force of each unit cylinder (20) after the attachment is large.

According to a second aspect of the present invention, there is provided a "body made of an elastic material, which comprises a tubular body having a C-shaped cross section and covering a certain range of the bar end portion (10). It is adhered to the part (10) '. In this handle grip, the open end of the C-shaped cross section is forcibly opened, and the bar end part (10) is provided with an adhesive agent interposed.
Externally. As a result, the handle grip is adhered to the bar end portion (10). When mounting the handle grip, it is not necessary to slide the handle grip with respect to the bar end portion (10).

According to a third aspect of the present invention, there is provided a means for solving the problem, "A coil-shaped portion (26) and a pair of annular bodies (25) (25) integrally connected to both ends in the axial direction of the coil-shaped portion (26). Then, the bar end portion (10) is tightly fitted on a certain range ”. In this one, for example, after pushing only the inner annular body (25) from the end portion of the bar end portion (10), the coiled portion (26) is wound around the bar end portion (10), and finally, The outer ring (25) to the bar end (1
It is attached by pushing in from the end of (0).

If the coil-shaped portion (26) is composed of a plurality of threads and has one winding or less, it cannot be attached by the above procedure, but in this case, the inner annular body (25) is pushed in halfway. Then, the outer annular body (25) is fitted thereinto to inflate the coil strip portion (26), and then the inner annular body (25) is pushed to the final position. When inflating the coil strip (26), the coil strip (26) may be twisted in the opposite direction to the winding direction, and in this case, the inner annular body (25). Be sure to twist back when pushing into the final position.

In any of the mounting procedures, the coiled portion (26) is mounted in a manner that it does not slide with respect to the bar end portion (10), and only the annular bodies (25) and (25) are attached to the bar end portion. All you have to do is to force it against (10). As a result, the bar end portion (10) is the same as the invention of claim 1 above.
Fixed to The means for solving the problems of the invention of claim 4 is "a pair of annular portions (27) (27) which are made of an elastic material as a whole in a tubular shape and are axially opposite to each other, and these annular portions (27) (27).
It is composed of a plurality of belt-shaped portions (28) and (28) which are integrally connected to each other and extend in the axial direction, and are tightly fitted to a certain range of the bar end portion (10) ”.

In this case, similarly to the latter mounting procedure of claim 3, when the inner annular portion (27) is pushed in halfway and then the outer annular portion (27) is fitted, the strip portion (28 ) (2
8) will be inflated. Then, the inner annular portion (2
When 7) is pushed to the final position, the strip portions (28) (28) are brought into close contact with the bar end portion (10). Also in this case, similarly to the invention of claim 3 described above, it suffices to forcibly push both end portions of the tubular body into the bar end portion (10).

Here, in the means of the inventions of claims 1, 3 and 4, as in the means of the invention of claim 5, in the case of "adhered to the bar end (10)", from the handle grip. In addition to the compressive force acting on the bar end portion (10), it is also fixed by adhesion. Further, in the means of the invention of claim 1, as in the means of the invention of claim 6, "the unit cylinders (20), (20) are set to have elasticity such that the open ends thereof can be turned upside down. With the unit cylinder (20) (20) positioned in the final position, the open end of the unit cylinder (20) (20) is turned inside out to turn it between the open end and the bar end (10). Adhesive means such as an adhesive can be interposed. Here, as in the means of the invention of claim 7, "the open end of the unit tube (20) is adhered by a double-sided tape" may be used.

Further, as in the means of the invention of claim 8,
In the case of "both ends of the handle grip in the axial direction are tightened by tightening bands", both ends in the axial direction are also tightened and fixed by the tightening bands.

[0014]

As described above, according to the first aspect of the present invention, even when the pressing force applied to the bar end portion (10) by each unit tube (20) is increased, the operation is performed when the unit tube (20) is pushed in. Since the frictional force to perform is smaller than the conventional one, it is easy to attach this handle grip to the bar end (10),
Moreover, it is difficult to move after mounting.

According to the second aspect of the present invention, when the handle grip is attached, it does not slide on the bar end portion (10), so that it can be attached to the bar end portion (10) more easily.
Further, since the handle grip is adhered to the bar end portion (10), the handle grip is surely prevented from falling off from the bar end portion (10). According to the invention of claim 3, the coil-shaped portion (26) of the handle grip is attached in a manner not to slide with respect to the bar end portion (10), and the annular bodies (25) at both ends in the axial direction.
Since only the bar end portion (10) needs to be externally fitted to the bar end portion (10) by force, the present invention can be mounted with a lighter force as compared with the conventional one described above.

According to the invention of claim 4, as in the invention of claim 3, only the annular portions (27) and (27) at both ends in the axial direction are forced to be fitted onto the bar end portion (10). , It can be attached with a lighter force than the conventional ones described above. In the invention of claim 5, the handle grip of the means of the inventions of claims 1, 3 and 4 is fixed also by adhesion, so that the handle grip is more reliably prevented from falling off.

In the invention of claim 6, the unit cylinders (20) (20)
Since the adhering work can be performed after the pushing-in work is completed, the work for interposing the adhesive is easy. In the invention of claim 8, since the handle grip is also fixed by the tightening force of the tightening band, the handle grip is more reliably prevented from falling off.

The unit cylinders (20) (20) are made of elastic synthetic resin, and the inner diameter thereof is set to be slightly smaller than the outer diameter of the bar end portion (10). Specifically, in a state where the unit cylinders (20) (20) are externally fitted to the bar end portion (10), both of them are in a slight interference fit state. Further, these unit cylinders (20) (20) are set to have such elasticity that the open ends thereof can be turned inside out.

The outer end of the outermost unit cylinder (20) among the three unit cylinders (20) (20) is closed. When attaching the handle grip (2) to the bar end portion (10), the unit tubes (20) and (20) are attached to the end portions of the bar end portion (10) in order from the inner one. Fit it and push it inwards. At this time, since the inner diameter of the unit cylinder (20) is smaller than the outer diameter of the bar end portion (10), the unit cylinder (20) is expanded in diameter with respect to the surface of the bar end portion (10). Slide. However, since the axial length (width) of the unit cylinder (20) is significantly smaller than the axial length of the conventional integrated handle grip (2), the frictional force during sliding is small. Will be things. Therefore, even if the elastic modulus of each unit cylinder (20) and the extension at the time of attachment are the same as those of the conventional one, they can be pushed in with a light force.

When the three unit tubes (20) (20) are pushed to their final positions, their end faces are in contact with each other. After that, as shown in FIG. 3, the open ends of the unit cylinders (20) are turned over and the double-sided tape (4) is attached to the surface of the bar end part exposed by this. Thereafter, when the open end of the unit cylinder (20) is returned to its original state, the unit cylinder (20) is bonded to the bar end portion (10). The double-sided tape (4) may be arranged so as to straddle the boundary between the unit tubes (20) (20). In this case, in addition to the compressive force acting on the bar end portion (10) from each unit cylinder (20), the handle grip is fixed by adhesion.

The unit cylinders (20) (20) are connected to the bar end (1
The means for adhering to (0) is not limited to the double-sided tape (4). For example, an adhesive may be used. As this adhesive, various known adhesives can be adopted. Furthermore, the unit tube
(20) (20) Mutually facing end faces may be bonded with an adhesive. In this embodiment, the handle grip (2) is divided into three parts, but it may be divided into more parts. Further, the material, hardness, etc. may be different for each unit cylinder (20). In this case, the feel when gripping the handle grip (2) can be set variously. Furthermore, there may be a gap between the unit cylinders (20) (20). [Second Embodiment] A handle grip according to the second embodiment.
As shown in FIG. 4, (2) is a tubular body made of elastic synthetic resin and having a C-shaped cross section. The inside diameter of the handle grip (2) is set to a size that matches the outside diameter of the bar end portion (10) in a state where the open portion (22) of the cross section is closed. The outer end of the handle grip (2) is closed.

Attach this handle grip (2) to the bar end
To attach it to (10), attach double-sided tape (4) (4) to the handle grip attachment area on the surface of this bar end (10), and then to the open part (22) of this handle grip (2). ) Forcibly open (state of Figure 5)
(2) is externally fitted within a certain range from the edge of the bar end portion (10). As a result, the handle grip (2) is bonded to the bar end portion (10). Further, in this state, the opening portion (22) is closed.
Instead of the double-sided tape (4), it may be adhered by another adhesive. The double-sided tape (4) is shown in FIG.
Instead of using a plurality of such as described above, a wide one covering almost the entire handle grip mounting area may be used.

Since the handle grip (2) of the second embodiment is closed at the outer end, the handle grip (2) at the outer end is not compressed after being attached, as compared with the case where the outer end is not closed. The force is large, and the disadvantage of peeling from the outer end does not occur. [Third Embodiment] A handle grip according to the third embodiment.

And an annular body (25) (25). These coiled parts (2
6) and the annular bodies (25) and (25) are cylindrical as a whole, and the wall thickness and the inner diameter of each part are set uniformly, and the inner diameter is the same as that of the first embodiment, and the bar end portion ( It is set to a size that provides an interference fit with respect to 10).

Attach this handle grip (2) to the bar end
In order to mount it on the (10), first, the inner annular body (25) is pushed from the end of the bar end (10) to a predetermined position. At this time, the annular body (25) can be pushed in with a lighter force as compared with the conventional integrated handle grip, as in the case of the first embodiment. After that, the coiled portion (26) is wound around the bar end portion (10) sequentially from the vicinity of the annular body (25). When this winding is completed, the outer annular body (25) is pushed into the bar end portion (10). As a result, the entire handle grip (2) is tightly fitted over the bar end portion (10), and the adjacent coil component portions are attached to each other in close contact with each other.

In addition to this attachment procedure, the inner annular body (25) is previously fitted to the middle part and the coil ridge (26) is twisted to increase the diameter, When the annular body (25) is fitted, and then the inner annular body (25) is pushed to the final position and the coil strip portion (26) is twisted back, the coiled portion (26) causes the bar end portion (26). It is closely attached to 10).

The coil strip portion (26) may be composed of a plurality of coil tubular portions. In this case, the coil strip portion (26) is attached to the bar end portion (10) by the latter procedure. In this case, if the coil lead of each coil tube is large,
Even if the coil strip (26) is not twisted, the diameter of the coil strip (26) is reduced by pushing the inner ring (25) to the intermediate position and then fitting the outer ring (25). Expanding.
