Abstract

A hand fixation band includes a fastening band, a sliding arm and a damping element. The fastening band has a connecting portion. A bottom surface of the connecting portion is defined as a contact surface. The sliding arm is connected with the fastening band. A top surface of one end of the sliding arm is recessed downward to form an accommodating groove. Several portions of a top surface of a bottom wall of the accommodating groove protrude upward to form a plurality of buckling blocks. The damping element is disposed in the accommodating groove and contacts with the contact surface. Several portions of a bottom surface of the damping element are recessed upward to form a plurality of buckling holes. The plurality of the buckling blocks are buckled in the plurality of the buckling holes.

First claim

What is claimed is:

1. A hand fixation band assembled to a rocker, comprising:
a fastening band having a main portion, and a connecting portion protruded outward from a middle of one end of the main portion, a bottom surface of the connecting portion being defined as a contact surface;
a sliding arm connected with the fastening band, a top surface of one end of the sliding arm disposed under a free end of the connecting portion being recessed downward to form an accommodating groove, several portions of a top surface of a bottom wall of the accommodating groove protruding upward to form a plurality of buckling blocks, the other end of the sliding arm opening at least one external fastening hole for being connected with the rocker, the fastening band being rotatable with respect to the sliding arm, rotatable angles of the fastening band with respect to the sliding arm being any angles in an approximately horizontal direction; and
a damping element disposed in the accommodating groove and contacting with the contact surface, several portions of a bottom surface of the damping element being recessed upward to form a plurality of buckling holes corresponding to the plurality of the buckling blocks, the plurality of the buckling blocks being buckled in the plurality of the buckling holes, the damping element being blocked by a periphery of the one end of the sliding arm,
wherein when the connecting portion of the fastening band is rotated with respect to the sliding arm, and one of the rotatable angles of the fastening band with respect to the sliding arm is 360 degrees in the approximately horizontal direction, the damping element is without being deformed and exposed beyond outer surfaces of the connecting portion of the fastening band and the sliding arm on account of a friction force pressing and pushing the damping element.

2. The hand fixation band as claimed in claim 1 , wherein the damping element is accommodated in and integrally molded in the accommodating groove by an integral injection molding technology.

3. The hand fixation band as claimed in claim 1 , wherein a material of the damping element is rubber.

4. The hand fixation band as claimed in claim 1 , wherein the sliding arm is made of a plastic material.

5. The hand fixation band as claimed in claim 1 , wherein the accommodating groove is shown as a circular ring shape, the damping element is shown as the circular ring shape and is matched with the accommodating groove.

6. The hand fixation band as claimed in claim 1 , wherein the plurality of the buckling blocks are arranged as an annulus shape, the plurality of the buckling holes are arranged as the annulus shape.

7. The hand fixation band as claimed in claim 1 , wherein a middle of a free end of the connecting portion opens a first fastening hole, a middle of the bottom wall of the accommodating groove is hollow, so the middle of the bottom wall of the accommodating groove has a second fastening hole, a middle of the damping element opens a third fastening hole, the first fastening hole, the third fastening hole and the second fastening hole are communicated with one another.

8. The hand fixation band as claimed in claim 7 , further comprising a fixing assembly fastened between the sliding arm and the fastening band, the fixing assembly including an upper fixing element and a lower fixing element, the upper fixing element having an upper base portion, and an upper fastening pillar protruded downward from a bottom surface of the upper base portion, the lower fixing element having a lower base portion, and a lower fastening pillar protruded upward from a top surface of the lower base portion, the lower fixing element opening a fixing groove extending vertically, and penetrating through a top surface of the lower fastening pillar and a bottom surface of the lower base portion, the fixing groove being disposed corresponding to the upper fastening pillar, the lower fastening pillar of the lower fixing element passing upward through the first fastening hole, the third fastening hole and the second fastening hole, the upper fastening pillar being assembled in the fixing groove, the upper fixing element and the lower fixing element being fixed with each other, and correspondingly the fastening band, the damping element and the sliding arm being combined by the fixing assembly.

9. The hand fixation band as claimed in claim 1 , wherein the damping element and the sliding arm are integrally molded by virtue of a double-material injection molding way of rubber and plastic materials, and adhesive forces generated among molecules of the rubber and plastic materials are stronger, when the connecting portion of the fastening band is rotated with respect to the sliding arm, the damping element is without being deformed and exposed beyond the outer surfaces of the connecting portion of the fastening band and the sliding arm on account of the friction force pressing and pushing the damping element.

10. A hand fixation band assembled to a rocker, comprising:
a fastening band having a main portion, and a connecting portion protruded outward from one end of the main portion, a bottom surface of the connecting portion being defined as a contact surface;
a sliding arm, one end of the sliding arm being mounted under one end of the connecting portion, a top surface of the one end of the sliding arm being recessed downward to form an accommodating groove, several portions of a top surface of a bottom wall of the accommodating groove protruding upward to form a plurality of buckling blocks, the other end of the sliding arm opening at least one external fastening hole for being connected with the rocker, the fastening band being rotatable with respect to the sliding arm, rotatable angles of the fastening band with respect to the sliding arm being any angles in an approximately horizontal direction;
a damping element disposed in the accommodating groove, the contact surface of the sliding arm contacting with a top surface of the damping element, several portions of a bottom surface of the damping element being recessed upward to form a plurality of buckling holes corresponding to the plurality of the buckling blocks, the plurality of the buckling blocks being buckled in the plurality of the buckling holes, the damping element being blocked by a periphery of the one end of the sliding arm; and
a fixing assembly fastened between the sliding arm and the fastening band,
wherein when the connecting portion of the fastening band is rotated with respect to the sliding arm, and one of the rotatable angles of the fastening band with respect to the sliding arm is 360 degrees in the approximately horizontal direction, the damping element is without being deformed and exposed beyond outer surfaces of the connecting portion of the fastening band, the sliding arm and the fixing assembly on account of a friction force pressing and pushing the damping element.

11. The hand fixation band as claimed in claim 10 , wherein the damping element is accommodated in and integrally molded in the accommodating groove by an integral injection molding technology.

12. The hand fixation band as claimed in claim 10 , wherein a material of the damping element is rubber.

13. The hand fixation band as claimed in claim 10 , wherein the sliding arm is made of a plastic material.

14. The hand fixation band as claimed in claim 10 , wherein the accommodating groove is shown as a circular ring shape, the damping element is shown as the circular ring shape and is matched with the accommodating groove.
