Functional component attaching member
In order to provide a functional component attaching member of which durability can be further improved because when a load is applied to a functional component while a vehicle is travelling, the load can also be borne by portions other than a wall portion opposite to a load direction, the present invention provides a rubber functional component attaching member (functional component mounting base 1 ) for fastening a functional component 29 to an inner surface 70 of a tire, comprising a bottom surface 4 that is fixed to the inner surface 70 of the tire, an attaching portion 2 having a recessed portion 2 A to which a functional component-side attaching portion 30 provided to the functional component 29 is attached, and a reinforcing material 20 embedded in a rubber portion on an outer side of the recessed portion 2 A.
1. A functional component attaching member which is formed of rubber for attaching a functional component to an inner surface of a tire, comprising:
a bottom surface to be fixed to the inner surface of the tire;
an attaching portion having a recessed portion in which a functional component-side attaching portion provided on the functional component is fitted in a fitted state; and
a reinforcing material embedded in a rubber portion on an outer side of the recessed portion,
wherein the reinforcing material is formed of a plurality of ring-shaped bodies arranged in the rubber to surround a periphery of the recessed portion;
wherein an inner bottom portion of the recessed portion is provided with semi-circular raised portions which are mutually fitted with semi-circular raised portions provided on a bottom of the functional component-side attaching portion.
2. The functional component attaching member according to claim 1 , wherein a diameter of the plurality of ring-shaped bodies changes along a radial direction of the tire.
3. A functional component attaching member which is formed of rubber for attaching a functional component to an inner surface of a tire, comprising:
a bottom surface to be fixed to the inner surface of the tire;
an attaching portion having a recessed portion in which a functional component-side attaching portion provided on the functional component is fitted in a fitted state; and
a reinforcing material embedded in a rubber portion on an outer side of the recessed portion,
wherein the reinforcing material is formed of one or more spiral bodies arranged in the rubber to surround a periphery of the recessed portion, a diameter of the one or more spiral bodies changing along a radial direction of the tire.
4. The functional component attaching member according to claim 1 , wherein the reinforcing material is arranged at a position corresponding to a tire peripheral direction of the functional component attaching member fixed to the inner surface of the tire.
5. The functional component attaching member according to claim 1 , wherein the reinforcing material is arranged to extend along an inner wall surface of the recessed portion.
6. The functional component attaching member according to claim 1 , wherein the reinforcing material is arranged to incline and extend from the recessed portion side to an outer circumferential edge side of the bottom surface.
7. The functional component attaching member according to claim 1 , wherein the reinforcing material is arranged to extend along the bottom surface.
8. The functional component attaching member according to claim 1 , wherein the reinforcing material is arranged to extend along a direction orthogonal to the bottom surface.
9. The functional component attaching member according to claim 1 wherein the reinforcing material is arranged to extend along an outer wall surface of the functional component attaching member.
10. The functional component attaching member according to claim 1 , wherein:
the recessed portion is formed to have an opening as an inlet/outlet for inserting/removing the functional component-side attaching portion formed to have a diameter smaller than a maximum diameter of the functional component-side attaching portion and a maximum diameter of the recessed portion corresponding to the maximum diameter of the functional component-side attaching portion;
the functional component-side attaching portion is fitted to the recessed portion in a fitted state by expanding the diameter of the opening to insert into the recessed portion; and
the reinforcing material is arranged at a position closer to a bottom surface side than a position of the maximum diameter of the recessed portion provided between the opening of the recessed portion and an inner bottom portion of the recessed portion.
11. The functional component attaching member according to claim 1 , wherein the reinforcing material is a steel cord or an organic fiber.
12. The functional component attaching member according to claim 3 , wherein the reinforcing material is arranged at a position corresponding to a tire peripheral direction of the functional component attaching member fixed to the inner surface of the tire.
13. The functional component attaching member according to claim 3 , wherein the reinforcing material is arranged to extend along an inner wall surface of the recessed portion.
14. The functional component attaching member according to claim 3 , wherein:
the recessed portion is formed to have an opening as an inlet/outlet for inserting/removing the functional component-side attaching portion formed to have a diameter smaller than a maximum diameter of the functional component-side attaching portion and a maximum diameter of the recessed portion corresponding to the maximum diameter of the functional component-side attaching portion;
the functional component-side attaching portion is fitted to the recessed portion in a fitted state by expanding the diameter of the opening to insert into the recessed portion; and
the reinforcing material is arranged at a position closer to a bottom surface side than a position of the maximum diameter of the recessed portion provided between the opening of the recessed portion and an inner bottom portion of the recessed portion.
15. The functional component attaching member according to claim 3 , wherein the reinforcing material is a steel cord or an organic fiber.
16. The functional component attaching member according to claim 3 , wherein an inner bottom portion of the recessed portion is provided with semi-circular raised portions which are mutually fitted with semi-circular raised portions provided on a bottom of the functional component-side attaching portion.
