Abstract

A profiled belt includes a belt body, a profile that is provided on a back surface of the belt body, and a fixation member that detachably fixes the profile to the belt body. The belt body includes a protrusion on the back surface. The profile includes a recess portion to which the protrusion is fitted. The fixation member fixes the profile to the belt body in a state where the protrusion has been fitted to the recess portion. The fixation member is removably inserted to the profile and the protrusion.

First claim

The invention claimed is:

1. A profiled belt comprising: a belt body; a profile that is provided on a back surface of the belt body; and a fixation member that detachably fixes the profile to the belt body, wherein:
the belt body includes a protrusion integrally formed with and on the back surface in a thickness direction of the belt body, wherein the belt body, at a position where the protrusion is formed, does not include any through holes in the thickness direction;
the profile includes a recess portion in which an entirety of the protrusion is fitted such that surfaces of the protrusion, in a belt longitudinal direction, are entirely covered by the profile;
the fixation member fixes the profile to the belt body in a state where the entirety of the protrusion has been fitted into the recess portion; and
the fixation member is removably inserted to the profile and the protrusion.

2. The profiled belt according to claim 1 , wherein the fixation member includes an extension portion that extends in a parallel direction parallel to the back surface and that penetrates the profile and the protrusion.

3. The profiled belt according to claim 2 , wherein the fixation member comprises a plurality of the extension portions, and a connection portion that connects one ends of the plurality of the extension portions in the parallel direction.

4. The profiled belt according to claim 3 , wherein the profile includes a connection portion receiving portion that receives the connection portion.

5. The profiled belt according to claim 2 , wherein:
the protrusion is longer in one direction of a longitudinal direction and a width direction of the belt body than in another direction; and
the parallel direction is the one direction.

6. The profiled belt according to claim 2 , wherein the fixation member further comprises an expansion portion that is provided in an end portion of the extension portion in the parallel direction, the end portion being not connected to another element, and that has a size in a perpendicular direction perpendicular to the parallel direction being larger at least in a part to be connected to the end portion than a size of the end portion in the perpendicular direction.

7. The profiled belt according to claim 6 , wherein: expansion portion receiving portion that receives the expansion portion.

8. The profiled belt according to claim 6 , wherein:
the expansion portion has a size in the perpendicular direction being reduced as going in the parallel direction away from the end portion of the extension portion; and
the size in the perpendicular direction of the expansion portion at the furthest end in the parallel direction from the end portion of the extension portion is equal to the size of the extension portion in the perpendicular direction or smaller than said size.

9. The profiled belt according to claim 6 , wherein the fixation member is made of metal.

10. The profiled belt according to claim 1 , wherein the fixation member does not protrude from an external surface of the profile.
