7. A handle grip with heater, comprising:
a cylindrical core body made of a synthetic resin, said core body having a flat and shallow groove formed spirally in a surface of the core body;
a metal strip having a width substantially identical with a width of said flat and shallow groove and being embedded within said flat and shallow groove, said metal strip generating heat by supplying an electric current through the metal strip;
a guide portion for guiding a pair of electric power supply conductors formed at one end of said core body viewed in a longitudinal direction, said electric power supply conductors being arranged along an outer periphery of the one end of the core body and being connected to respective end portions of said metal strip; and
said electric power supply conductors are turned over around a direction converting portion at said guide portion into a same or opposite direction to a direction in which the electric power supply conductors are introduced into the guide portion and are drawn outwardly from the guide portion.
8. The handle grip with heater according to claim 7, wherein said guide portion includes an electric power supply conductor guide recess around the direction converting portion, and the electric power supply conductors are turned over along said electric power supply conductor guide recess.
9. The handle grip with heater according to claim 8, comprising at least one slip preventing ridge formed on a surface of said direction converting portion.
10. The handle grip with heater according to claim 8, comprising a plurality of slip preventing ridges formed on a surface of said direction converting portion.
11. The handle grip with heater according to claim 7, comprising at least one slip preventing ridge formed on a surface of said direction converting portion.
12. The handle grip with heater according to claim 7, comprising a plurality of slip preventing ridges formed on a surface of said direction converting portion.
13. The handle grip with heater according to claim 7, wherein:
said core body has an electric power supply conductor guide recess formed in an outer surface of the core body in a longitudinal direction such that the conductor guide recess has a depth larger than a depth of said flat and shallow groove;
one of two electric power supply conductors is embedded within said electric power supply conductor recess; and
an end portion of said one of the two electric power supply conductors is connected to a remote end portion of said metal strip.
14. The handle grip with heater according to claim 7, wherein said core body has a number of molding holes in an area except for the flat and shallow groove.
15. The handle grip with heater according to claim 14, comprising an insulating synthetic rubber molded on said core body is formed by molding such that said metal strip, electric power supply wire, outer and inner surface of said core body are covered with the synthetic rubber which is penetrated through said molding holes.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A tension rod comprising:
a first outer shaft;
a second inner shaft slideably received by the first outer shaft and rotatable about a longitudinal axis of the tension rod; and
a tension rod mechanism operatively coupling the first outer shaft and the second inner shaft, the tension rod mechanism comprising:
a tapered first threaded shaft having a first end and an opposing second end, and being completely threaded with a first screw thread having a first thread direction from the first end to the second end, and completely tapered from the first end to the second end, a diameter of the first end of the tapered first threaded shaft being larger than a diameter of the second end of the tapered first threaded shaft;
a first expandable collar threadingly engaged with the first threaded shaft, the first collar configured to be received in the first outer shaft for rotational movement therewith and slidable axial movement relative thereto and to apply an outwardly-directed radial force to the first outer shaft;
a second threaded shaft having a second screw thread with a second thread direction opposite the first thread direction, the second threaded shaft being fixedly connected to the first threaded shaft; and
a second collar threadingly receiving the second threaded shaft therein and being fixedly received in the second inner shaft for movement therewith, the second collar having a longitudinally extending second collar stopper projecting in the direction of the central flange stopper;
a center flange integrally formed as a single part with and located between the first threaded shaft and the second threaded shaft, the center flange having a radially projecting central flange stopper;
wherein relative rotation between the first outer shaft and the second inner shaft in a first direction draws the second collar stopper into circumferential abutment with the central flange stopper and prevents relative rotation between the second collar and the second threaded shaft, further rotation between the first out shaft and the second inner shaft after abutment of the stoppers causes the tapered first threaded shaft to apply the outwardly directed radial force to fixedly couple the first collar to the first outer shaft, after the first collar is fixedly coupled to the first outer shaft relative rotation between the first outer shaft and the second inner shaft in an opposite second direction increases the distance between the first and second collars.
2. The tension rod mechanism according to claim 1, wherein the first collar has a longitudinally extending circumferentially expandable slot.
3. The tension rod mechanism according to claim 1, wherein the second threaded shaft has a constant diameter along the longitudinal axis.
