Abstract

Disclosed are adjustment mechanisms and structures including one or more adjustment mechanisms. An adjustment mechanism comprising a casing, first and second arms, a second arm, a button, and an elastic member. The first and second arms are movably disposed in a channel of the casing. The button is operably coupled with the first and second arms and selectively pushes a first end of the first arm out of a first side of the casing and a second end of a second arm out of a second side of the casing. The elastic member abuts the casing and button such that the button is held at a desired position and consequently the first and second arms are held at a desired state under normal conditions. The adjustment mechanisms of the present disclosure provide an easy, convenient and safe means for height or length adjustment.

First claim

What is claimed is:

1. An adjustment mechanism comprising:
a casing comprising a first side, a second side and a channel between the first and second sides;
a first arm disposed in the channel of the casing and movable with respect to the casing along a first direction, the first arm comprising a first end adjacent to the first side of the casing;
a second arm disposed in the channel of the casing and movable with respect to the casing along the first direction, the second arm comprising a second end adjacent to the second side of the casing;
a button coupled with the first and second arms and movable with respect to the casing along a second direction that is substantially perpendicular to the first direction, wherein:
one or more first slots are formed at one of the first arm and the button, each first slot including two sides that are substantially parallel to each other and sloped with respect to the first direction and the second direction;
one or more first pins are formed at the other of the first arm and the button, wherein each respective first pin in the one or more first pins is oriented substantially perpendicularly to the first and second directions such that, cross-sectional-wise, each respective first pin in the one or more first pins is disposed in a corresponding first slot in the one or more first slots and movable along the corresponding first slot, wherein the one or more first pins and the one or more first slots collectively transfer the movement of the button along the second direction to the movement of the first arm along the first direction, thereby selectively pushing the first end of the first arm out of the first side of the casing;
one or more second slots are formed at one of the second arm and the button, each second slots including two sides that are substantially parallel to each other and sloped with respect to the first direction and the second direction; and
one or more second pins are formed at the other of the second arm and the button, each respective second pin in the one or more second pins is oriented substantially perpendicularly to the first and second directions such that, cross-sectional-wise, each respective second pin in the one or more second pins is disposed in a corresponding second slot in the one or more second slots and movable along the corresponding second slot, wherein the one or more second pins and the one or more second slots collectively transfer the movement of the button along the second direction to the movement of the second arm along the first direction, thereby selectively pushing the second end of the second arm out of the second side of the casing; and

at least two first elastic members aligned substantially in the second direction, each comprising a first end abutting the casing and a second end abutting the button, thereby holding the button at a fixed position in the absence of any external force such that the first end of the first arm remains outside of the first side of the casing and the second end of the second arm remains outside of the second side of the casing, wherein one of the at least two first elastic members is disposed adjacent to the first arm and another of the at least two first elastic members is disposed adjacent to the second arm.

2. The adjustment mechanism of claim 1 , wherein the button comprises at least two cavities, each for accommodating at least a portion of a first elastic member in the at least two first elastic members.

3. The adjustment mechanism of claim 1 , wherein:
the button comprises one or more fifth slots in the second direction; and
the casing comprises one or more fifth pins, each respective fifth pin in the one or more fifth pins is operably coupled with a corresponding fifth slot in the one or more fifth slots and movable along the corresponding second slot to guide the movement of the button in the second direction.

4. The adjustment mechanism of claim 1 , wherein:
the first arm comprises a first surface sloped with respect to the first and second directions;
the second arm comprises a second surface sloped with respect to the first and second directions; and
the button comprises a third surface and a fourth surface sloped with respect to the first and second directions, wherein
the third surface is operably coupled with the first surface of the first arm, thereby transferring the movement of the button along the second direction to the movement of the first arm along the first direction, and
the fourth surface is operably coupled with the second surface of the second arm, thereby the movement of the button along the second direction to the movement of the second arm along the first direction.

5. An adjustment mechanism comprising:
a casing comprising a first side, a second side and a channel between the first and second sides;
a first arm disposed in the channel of the casing and comprising a first end adjacent to the first side of the casing, wherein the first arm is movable with respect to the casing along a first direction to selectively allow the first end of the first arm to protrude from the first side of the casing;
a second arm disposed in the channel of the casing and comprising a second end adjacent to the second side of the casing, wherein the second arm is movable with respect to the casing along the first direction to selectively allow the second end of the second arm to protrude from the second side of the casing;
a button operably coupled with the first and second arms and movable with respect to the casing along a second direction substantially perpendicular to the first direction, wherein movement of the button along the second direction causes movement of the first and second arms along the first direction; and
one or more first elastic members, each comprising a first end abutting the casing and a second end abutting the button, thereby holding the button at a fixed position in the absence of any external force such that the first end of the first arm remains outside of the first side of the casing and the second end of the second arm remains outside of the second side of the casing;
wherein:
the first arm comprises a first surface sloped with respect to the first and second directions;
the second arm comprises a second surface sloped with respect to the first and second directions;
the button comprises a third surface and a fourth surface sloped with respect to the first and second directions, wherein
the third surface is operably coupled with the first surface of the first arm, thereby transferring the movement of the button along the second direction to the movement of the first arm along the first direction, and
the fourth surface is operably coupled with the second surface of the second arm, thereby the movement of the button along the second direction to the movement of the second arm along the first direction;

the first arm comprises one or more first slots each substantially parallel to the first surface;
the second arm comprises one or more second slots each substantially parallel to the second surface; and
the button comprises one or more first pins and one or more second pins, wherein
each respective first pin in the one or more first pins is operably coupled with a corresponding first slot in the one or more first slots and movable along the corresponding first slot to guide the movement of the third surface with respect to the first surface of the first arm;
each respective second pin in the one or more second pins is operably coupled with a corresponding second slot in the one or more second slots and movable along the corresponding second slot to guide the movement of the fourth surface with respect to the second surface of the second arm.

6. The adjustment mechanism of claim 5 , wherein:
the first arm comprise
