Abstract

A hand fixation band includes a fastening band, a sliding arm and a damping element. The fastening band has a main portion, and a connecting portion protruded outward from one end of the main portion. A bottom surface of the connecting portion is defined as a contact surface. The sliding arm is connected with the fastening band. One end of the sliding arm disposed under the connecting portion is recessed downward to form an accommodating groove. A top of a peripheral wall of the accommodating groove is inclined outward from bottom to top to form a first inclined surface. The damping element is disposed in the accommodating groove and contacts with the contact surface. A periphery of a bottom surface of the damping element is inclined outward from bottom to top to form a second inclined surface. The first inclined surface contacts with the second inclined surface.

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, a top of a peripheral wall of the accommodating groove being inclined outward from bottom to top to form a first inclined surface, the other end of the sliding arm opening at least one external fastening hole used for being connected with the rocker, the fastening band being rotatable with respect to the sliding arm, rotation 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 a top surface of the damping element contacting with the contact surface, a periphery of a bottom surface of the damping element being inclined outward from bottom to top to form a second inclined surface corresponding to and matched with the first inclined surface, the first inclined surface contacting with the second inclined surface, the second inclined surface abutting against the first inclined surface, a bottom wall of the accommodating groove and a bottom of the peripheral wall of the accommodating groove being located under a middle of the bottom surface of the damping element, the middle of the bottom surface of the damping element being spaced from a top surface of the bottom wall of the accommodating groove to form a buffering space between the middle of the bottom surface of the damping element and the top surface of the bottom wall of the accommodating groove,
wherein when the fastening band is rotated with respect to the sliding arm, the buffering space makes the middle of the bottom surface of the damping element be without contacting the top surface of the bottom wall of the accommodating groove to reduce a resistance force among the damping element, the sliding arm and the fastening band.

2. The hand fixation band as claimed in claim 1 , wherein the accommodating groove is shown as a circular ring shape.

3. The hand fixation band as claimed in claim 1 , wherein a middle of the free end of the connecting portion opens a first fastening hole, a middle of the bottom wall of the accommodating groove has a second fastening hole penetrating through a middle of the sliding arm, 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.

4. The hand fixation band as claimed in claim 3 , wherein the second fastening hole is communicated with the accommodating groove.

5. The hand fixation band as claimed in claim 3 , 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.

6. 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 connected with the fastening band, 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, a top of a peripheral wall of the accommodating groove being inclined outward from bottom to top to form a first inclined surface, the other end of the sliding arm opening at least one external fastening hole used for being connected with the rocker, the fastening band being rotatable with respect to the sliding arm, rotation 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, a top surface of the damping element contacting with the contact surface, a periphery of a bottom surface of the damping element being inclined outward from bottom to top to form a second inclined surface corresponding to and matched with the first inclined surface, the first inclined surface contacting with the second inclined surface, the second inclined surface abutting against the first inclined surface, a bottom wall of the accommodating groove and a bottom of the peripheral wall of the accommodating groove being located under a middle of the bottom surface of the damping element, the middle of the bottom surface of the damping element being spaced from a top surface of the bottom wall of the accommodating groove to form a buffering space between the middle of the bottom surface of the damping element and the top surface of the bottom wall of the accommodating groove; and
a fixing assembly fastened between the sliding arm and the fastening band,
wherein when the fastening band is rotated with respect to the sliding arm, the buffering space makes the middle of the bottom surface of the damping element be without contacting the top surface of the bottom wall of the accommodating groove to reduce a resistance force among the damping element, the sliding arm and the fastening band.

7. The hand fixation band as claimed in claim 6 , wherein the accommodating groove is shown as a circular ring shape.

8. The hand fixation band as claimed in claim 6 , 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 has a second fastening hole penetrating through a middle of the sliding arm, 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.

9. The hand fixation band as claimed in claim 8 , wherein the second fastening hole is communicated with the accommodating groove.

10. The hand fixation band as claimed in claim 8 , wherein the fixing assembly includes an upper fixing element and a lower fixing element, the upper fixing element has an upper base portion, and an upper fastening pillar protruded downward from a bottom surface of the upper base portion, the lower fixing element has a lower base portion, and a lower fastening pillar protruded upward from a top surface of the lower base portion, the lower fixing element opens 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 is d
