Handle sleeve
A handle sleeve includes a tube, which is made by an elongated piece rolled. The elongated piece has a first surface, a second surface and two bonding portions at two elongated sides thereof. The two bonding portions having the first surface are bonded together face to face to form a connecting portion. The tube has the first surface at an exterior thereof and has the second surface and the connecting portion at an interior thereof.
1. Field of the Invention
The present invention relates generally to a handle device, and more particularly to a handle sleeve, which is a tub-like member to be sleeved onto a handle.
2. Description of the Related Art
Handles of rackets, shafts or bicycles usually are provided with a pad. The conventional pads are a tube-like sleeve fitted to the handle or a band wound on the handle. The pads provide the user a well condition of gripping the handle and provide the functions of absorption of vibration, skidproof and so on.
The conventional band-typed pad is to wind an elongated band on the handle spirally. Such pad cannot resist a torque exerted by the user and the band might be loosened by the torque. The tube-typed pad, i.e. sleeve, is to fit a tube to the handle directly. Such sleeve resists a torque exerted thereon by the user. However, the sleeves were usually made by injection molding and were made of rubber. But the rubber is too hard to provide a well condition of gripping the handle.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a handle sleeve, which has advantages of simple structure, easy fabrication and well gripping condition.
According to the objective of the present invention, a handle sleeve is mainly formed by a tube, which is made by an elongated piece rolled. The elongated piece has a first surface, a second surface opposite the first surface, and two bonding portions at two elongated sides thereof. The two bonding portions having the first surface are bonded together face to face to form a connecting portion. The tube has the first surface at an exterior thereof and has the second surface and the connecting portion at an interior thereof.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in
In fabrication, the bonding portions 26 of the piece 21 having the first surface 24 are attached to each other face to face and stitched together, as shown in
As shown in
The tube 20 of the present invention is not made by injection molding as the conventional handle sleeve does, so that the material, which makes the tube 20, is not limited in the material that can be used in injection molding. The tube 20 can be made by two materials as described above that provides a well performance both in comfortable condition of gripping and absorption of vibration. The double materials tube 20 can be easily made by two layers stacked. The present invention has the advantages of easy to fabricate and lower cost. The tube 20 also can be made by three or more various layers to enhance the properties of comfortable condition of gripping, absorption of sweat and absorption of vibration.
As shown in
The inner tube 31, which is made by rubber as the conventional one, has an open end 32 and a close end 33.
The winding layer 34, which is a band 35 wound on the inner tube 31, is provided at an exterior of the inner tube 31. The band 35 is made by a foaming material, so that the winding layer 34 is soft.
The tube 40, which is similar to the tube 20 of the first preferred embodiment, is made of a single layer of polyurethane piece and turned, as shown in
In fabrication, the band 35 is wound on the inner tube 31 to form the winding layer 34, and then the inner tube 31 has the open end 32 thereof inserted into the tube 40 via a second end 42 of the tube 40, as shown in
The handle sleeve 30 of the second preferred embodiment keeps the advantages of the handle sleeve 10 of the first preferred embodiment. In addition, the tube 40 protects the winding layer 34 from loosening after a long time of use. In fabrication, the inner tube, the winding layer and the tube can be made of various materials to provide various performances.
Claims
1. A handle sleeve, comprising a tube, which is made by an elongated piece rolled, wherein the piece has a first surface, a second surface and two bonding portions at two elongated sides thereof, wherein said two bonding portions having the first surface are bonded together face to face to form a connecting portion, wherein the tube has the first surface at an exterior thereof and has the second surface and the connecting portion at an interior thereof.
2. The handle sleeve as defined in claim 1, wherein the piece has a plurality of layers stacked.
3. The handle sleeve as defined in claim 2, wherein the piece has a first layer made of polyurethane and a second layer made of a foaming material stacked.
