[0015] [Implementation Method]

[0016] like Figure 1 As shown, the handlebar with a handle according to the present embodiment includes a handle 10 and a handlebar 12. The handle 10 is mounted on the handlebar 12. The handlebar 12 is provided on a mobile body, a cart, a working machine, etc. As a mobile body, for example, a two-wheeled motorcycle, a bicycle, a buggy, etc. can be listed. As a cart, for example, a wheelbarrow, etc. can be listed. As a working machine, for example, a lawn mower, etc. can be listed.

[0017] like Figure 2 As shown in FIG. 1 , the handle 10 includes a cylindrical member 20 and a cover member 22. The cylindrical member 20 is an inner portion of the handle 10. The cylindrical member 20 is formed of, for example, a thermoplastic resin. The handlebar 12 is inserted through the cylindrical member 20.

[0018] The cover member 22 is an outer portion of the handle 10. The cover member 22 is formed of, for example, rubber. The cover member 22 covers the tubular member 20. The cover member 22 is mounted on the tubular member 20 in a manner that does not move relative to the tubular member 20. The length of the cover member 22 in the extension direction of the cover member 22 is longer than the length of the tubular member 20 in the extension direction of the tubular member 20.

[0019] The cover part 22 has a cover body part 22A and a separation part 22B. The cover body part 22A is a tubular part that abuts against the outer peripheral surface of the tubular part 20. The separation part 22B is a part that is separated from the tubular part 20 at one end of the tubular part 20. The separation part 22B extends in a manner that radially expands from the cover body part 22A to one end of the tubular part 20. The outer shape of the separation part 22B is larger than the outer shape of the cover body part 22A. For example, the outer shape of the separation part 22B is a truncated cone shape. Concave and convex 26 are formed on the inner peripheral surface of the separation part 22B. The separation part 22B does not abut against the outer peripheral surface of the tubular part 20 and can be rolled up.

[0020] The cover member 22 has a protrusion 28 protruding from the inner peripheral surface of the cover member 22 at the other end of the tubular member 20. The protrusion 28 penetrates a protrusion insertion hole 20RH formed in the tubular member 20 and extends toward the inside of the tubular member 20.

[0021] like Figure 3 As shown, in a cross section orthogonal to the length direction of the tubular member 20 (the direction in which the tubular member 20 extends), the inner circumference of the tubular member 20 is formed into a substantially elliptical shape. A pair of recesses 30 are formed on the inner circumference of the tubular member 20. In the absence of a pair of recesses 30, the inner circumference of the tubular member 20 is substantially a true ellipse. The length A of the major axis of the ellipse is greater than the length B of the minor axis of the ellipse (A>B). In addition, a pair of recesses 30 may be formed on the inner circumference of a perfect circle in such a way that the inner circumference as a whole becomes substantially elliptical.

[0022] The pair of recesses 30 are respectively located on the inner surface of the tubular member 20 in the major axis direction D1 of the ellipse. The pair of recesses 30 are arranged opposite to each other. Figure 2 As shown, the pair of recesses 30 extend from one end to the other end of the tubular member 20 along the longitudinal direction of the tubular member 20. The pair of recesses 30 are provided with the aforementioned protrusion insertion holes 20RH.

[0023] like Figure 3 As shown, the outer peripheral surface of the tubular member 20 is formed into a substantially circular shape in a cross section perpendicular to the longitudinal direction of the tubular member 20. A flat portion 32 is formed on the outer peripheral surface of the tubular member 20. When the flat portion 32 is not formed, the outer peripheral surface of the tubular member 20 is substantially a perfect circle.

[0024] A through hole 20TH is formed in the tubular member 20. The through hole 20TH is located at one end of the tubular member 20. The through hole 20TH extends along the minor axis direction D2 of the ellipse. The through hole 20TH opens at a flat portion 32 of the outer peripheral surface of the tubular member 20. The flat portion 32 serves as a base for a fixing member 40 inserted through the through hole 20TH. The fixing member 40 is a member for fixing the tubular member 20 to the handlebar 12. In the present embodiment, the fixing member 40 is a rivet, but is not limited thereto. For example, the fixing member 40 may also be a screw, a bolt, or the like. In addition, the through hole 20TH is exposed when the separation portion 22B of the cover member 22 is rolled up.

[0025] A handlebar through hole 12TH is formed in the handlebar 12 in correspondence with the through hole 20TH of the tubular member 20. The fixing member 40 inserted through the through hole 20TH of the tubular member 20 is inserted through the handlebar through hole 12TH.

[0026] like Figure 4As shown, a protrusion insertion hole 20RH is formed in the cylindrical member 20. As described above, the protrusion insertion hole 20RH is located in a pair of recesses 30 in the other end of the cylindrical member 20. The protrusion insertion hole 20RH extends along the major axis direction D1 of the ellipse. The protrusion 28 of the cover member 22 is inserted into the protrusion insertion hole 20RH.

[0027] Figure 5 1 is a cross-sectional view showing a handle 100 of a comparative example. The handle 100 of the comparative example is composed of a circular tube portion 50 made of resin, a ring portion 52 made of rubber, and a cover portion 54 made of rubber. The ring portion 52 is mounted on the inner circumference of the circular tube portion 50. The cover portion 54 is mounted on the outer circumference of the circular tube portion 50. The inner circumference of the ring portion 52 is formed with concave portions and convex portions along the circumferential direction.

[0028] When attaching the comparative grip 100 to the handlebar 12, the operator inserts the ring 52 into the handlebar 12. When the ring 52 is inserted into the handlebar 12, the grip 100 presses the outer peripheral surface of the handlebar 12. The mounting strength of the grip 100 and the handlebar 12 is maintained by this pressing force.

[0029] Manufacturing errors may occur in the handle 100. For example, the closer the height of the convex portion of the ring 52 is to the upper limit of the tolerance range, the greater the friction resistance between the handle 12 and the ring 52 when the ring 52 is inserted into the handle 12. Similarly, the closer the outer diameter of the handle 12 is to the upper limit of the tolerance range, the greater the friction resistance between the handle 12 and the ring 52. Therefore, the operator needs to forcibly press the handle 100. As a result, the installation work cannot be carried out smoothly.

[0030] On the other hand, as the height of the convex portion of the ring portion 52 approaches the lower limit of the tolerance range, the contact area between the handlebar 12 and the ring portion 52 decreases, and the above-mentioned pressing force decreases. Similarly, as the outer diameter of the handlebar 12 approaches the lower limit of the tolerance range, the above-mentioned pressing force decreases. Therefore, it is difficult to maintain the mounting strength.

[0031] When it is difficult to maintain the mounting strength, in order to compensate for the mounting strength, it is conceivable to apply an adhesive to the inner peripheral surface of the ring portion 52 and then insert the ring portion 52 into the handlebar 12 .

[0032] However, the amount of adhesive applied or the range of adhesive application is likely to depend on the skill of the operator. Therefore, depending on the skill level of the operator, the adhesive disposed between the handlebar 12 and the grip 100 may be uneven, resulting in variations in mounting strength.

[0033] In contrast, in the present embodiment, the inner circumferential surface of the tubular component 20 for inserting the handlebar 12 is formed into an elliptical shape. Therefore, the contact surface between the tubular component 20 and the handlebar 12 in the long axis direction D1 can be reduced at the long diameter portion (long axis portion) of the tubular component 20. Therefore, even if at least one of the outer diameter of the handlebar 12 and the inner diameter of the tubular component 20 is close to the upper limit of the tolerance range, the friction resistance between the handlebar 12 and the tubular component 20 can be reduced. As a result, the installation of the handlebar 10 can be easily implemented. On the other hand, the short diameter portion (short axis portion) of the tubular component 20 can strongly abut against the handlebar 12, and as a result, the installation state installed on the handlebar 12 can be maintained.

[0034] In addition, in the present embodiment, the through hole 20TH through which the fixing member 40 is inserted is formed in the tubular member 20, and the through hole 20TH extends along the minor axis direction D2 of the ellipse. Therefore, in a state where the handlebar 12 and the tubular member 20 are in contact, the handlebar 12 and the tubular member 20 can be fixed by the fixing member 40. Therefore, even if at least one of the outer diameter of the handlebar 12 and the inner diameter of the tubular member 20 is close to the lower limit of the tolerance range, it is possible to suppress the deviation of the mounting strength and firmly fix.

[0035] In addition, in the present embodiment, the cover member 22 has a separation portion 22B separated from the cylindrical member 20 at one end of the cylindrical member 20 where the through hole 20TH is located. Therefore, when the fixing member 40 is inserted into the through hole 20TH, the operator can put his fingers into the separation portion 22B to roll up the cover member 22. In addition, when the handle 10 is used, the through hole 20TH can be hidden, so the appearance design is good.

[0036] In addition, in this embodiment, the concavo-convex 26 is formed on the inner peripheral surface of the separation portion 22B. Therefore, it is easier to roll up the cover member 22 than when the concavo-convex 26 is not formed.

[0037] In addition, in the present embodiment, the concave portion 30 is formed along the length direction of the tubular member 20 on the inner surface portion of the tubular member 20 in the major axis direction D1 of the ellipse. Therefore, even if the outer diameter of the handlebar 12 is close to the upper limit or lower limit of the tolerance range, the handlebar 10 can be easily mounted without reducing the mounting strength. In addition, even if the handlebar 12 is of a different type, the handlebar 10 can be easily mounted without reducing the mounting strength.

[0038] In addition, in the present embodiment, the protrusion 28 protruding from the inner peripheral surface of the cover member 22 passes through the protrusion insertion hole 20RH of the recess 30 and extends toward the inside of the tubular member 20. Therefore, even if there is a gap between the tubular member 20 and the handlebar 12, the handlebar 10 can be prevented from swinging in the long axis direction D1 with the fixing member 40 as a fulcrum.

[0039] As described above, according to the present embodiment, it is possible to realize the handle 10 that is easy to attach without reducing the attachment strength.

[0040] The above-mentioned embodiment may be modified as follows.

[0041] (Variant 1)

[0042] A pair of through holes 20TH facing each other may be formed in the tubular member 20 along the minor axis direction D2. Alternatively, a pair of through holes 20TH may be formed in the tubular member 20 at the other end of the tubular member 20. In these cases, the tubular member 20 can be fixed to the handlebar 12 at two locations. As a result, the mounting strength of the handlebar 10 relative to the handlebar 12 can be improved.

[0043] (Variant 2)

[0044] The handlebar through hole 12TH may not be formed in the handlebar 12. In this case, for example, the through hole 20TH of the tubular member 20 may be formed as a threaded hole, and the tubular member 20 may be fixed to the handlebar 12 using a fixing member 40 such as a set screw screwed into the threaded hole.

[0045] (Variant 3)

[0046] The tubular member 20 may be longer than the cover member 22 , or may be substantially the same length as the cover member 22 .

[0047] (Variant 4)

[0048] The cover member 22 may include the separation portion 22B at the other end of the tubular member 20. In addition, the cover member 22 may include the separation portion 22B at one end of the tubular member 20 and at the other end of the tubular member 20, respectively.

[0049] (Variant 5)

[0050] The protrusions 28 may be arranged at intervals in the length direction of the tubular member 20. Figure 6 As shown, the protrusion 28' protruding from the recess 30 may be provided in the recess 30. In this case, the protrusion insertion hole 20RH is not formed. In addition, the tubular member 20 is preferably formed of rubber or the like.

[0051] (Variant 6)

[0052] The handle 10 may be a handle heater. In this case, a heat conducting element is disposed between the tubular member 20 and the cover member 22. The heat conducting element may be made of, for example, a metal foil of copper, aluminum, nickel, titanium, or the like.

[0053] [Note]

[0054] The following additional notes are disclosed in relation to the above-mentioned embodiments and modifications.

[0055] (Note 1)

[0056] The utility model relates to a handle (10), which comprises a tubular component (20) and a cover component (22), wherein a handlebar (12) is inserted into the tubular component (20); the cover component (22) covers the tubular component, and the inner circumference of the tubular component is elliptical on a cross section perpendicular to the length direction of the tubular component, and a through hole (20TH) for a fixing component (40) to be inserted is formed in the tubular component, wherein the fixing component (40) is used to fix the handlebar and the tubular component, and the through hole extends along the minor axis direction (D2) of the ellipse.

[0057] Accordingly, the short diameter portion (short axis portion) of the tubular component can strongly abut against the handlebar, and the long diameter portion (long axis portion) of the tubular component can allow for manufacturing errors of the handlebar or the tubular component. Therefore, while reducing the contact surface between the tubular component and the handlebar, the handlebar and the tubular component can also be firmly fixed together. In addition, since the handlebar and the tubular component are fixed together by a through hole provided on the short diameter side, it becomes a structure capable of suppressing the movement of the fastening portion (fixing part). As a result, a handle that is easy to install on the handlebar and can maintain an installed state on the handlebar can be realized.

[0058] (Note 2)

[0059] According to the handle described in Supplement 1, the through hole may be located at the end of the tubular member, and the cover member may have a separation portion (22B) separated from the tubular member at the end of the tubular member. Accordingly, when the fixing member is inserted into the through hole, the operator can put his fingers into the separation portion to roll up the cover member. In addition, the through hole can be hidden when the handle is used, so the appearance design is good.

[0060] (Note 3)

[0061] According to the handle described in Supplementary Note 2, the inner peripheral surface of the separation portion may be formed with concavo-convex (26). This makes it easier to roll up the cover member than when the concavo-convex is not formed.

[0062] (Note 4)

[0063] According to the handle described in Supplementary Note 1, a recess (30) may be formed along the length direction of the tubular member on the inner surface portion of the tubular member in the direction (D1) of the major axis of the ellipse. Thus, even if there is a manufacturing error in the handlebar or the type of the handlebar is different, the handlebar can be easily installed without reducing the installation strength.

[0064] (Note 5)

[0065] According to the handle described in Supplement 4, the cover member may be provided with a protrusion (28) protruding from the inner peripheral surface of the cover member, and the protrusion passes through the protrusion insertion hole (20RH) formed in the tubular member and extends toward the inner side of the tubular member. Thus, even if there is a gap between the tubular member and the handlebar, the handlebar can be prevented from swinging in the long axis direction with the fixed member as a fulcrum.

[0066] (Note 6)

[0067] According to the handle described in Supplementary Note 4, the recessed portion may be provided with a protrusion (28') protruding from the recessed portion. Thus, even if there is a gap between the tubular member and the handlebar, the handlebar can be prevented from swinging in the longitudinal direction with the fixed member as a fulcrum.

[0068] (Note 7)

[0069] The present disclosure is a handlebar with a grip to which the grip described in any one of Supplementary Notes 1 to 6 is attached.

[0070] In addition, the present invention is not limited to the above-mentioned disclosure, and various structures can be adopted within the scope not departing from the gist of the present invention.
