Abstract
Abstract A device for precisely positioning and locking an object in a selective position including a first arm, a second arm, a third arm and a fourth arm, as well as an L-shaped arm connecting the third and fourth arms. The arms are structured so as to movably connect a support for an object, such as a head rest, to a base member, such as an operating table. The arms are structured so as to slidably engage with one another in order to allow positioning of the support for the object in any desired position in a three dimensional space. The first arm is slidably mounted to a connection to the base member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
284 words
A device in combination with an object and a base for positioning said object relative to said base comprising: first, second, third, and fourth arms, an L-shaped arm connecting said third arm and said fourth arm, said first and third arms having first and second opposite ends, each said end of said respective first and third arms having holding members movable between a locked position and unlocked position, said first and third arms each further including movable actuating means for substantially simultaneously moving each of said holding members of said respective first and third arms between said locked and unlocked positions in response to movement of said respective actuating means between an actuated position and a deactuated position, a first connecting means releasably and rotatably engaged with said second arm by said holding member of said second end of said first arm, said first connecting means being slidable with respect to said second arm, a second connecting means releasably and rotatably engaged with said second arm at an end thereof opposite said first arm by said holding member of said first end of said third arm, said third arm being slidable with respect to said second arm, a third connecting means releasably and rotatably engaged with a first end of said L-shaped arm by said holding member at said second end of said third arm, a fourth connecting means releasably and rotatably engaged with a second end of said L-shaped arm by a clamp disposed at a first end of said fourth arm, said fourth arm including a connection to a positioning member adjacent a second end of said fourth arm, said connection being able to lock said positioning member in a desired position.
Claim 2
Independent Claim
284 words
A device in combination with an object and a base for positioning said object relative to said base comprising: first, second, third, and fourth arms, an L-shaped arm connecting said third arm and said fourth arm, said first and third arms having first and second opposite ends, each said end of said respective first and third arms having holding members movable between a locked position and unlocked position, said first and third arms each further including movable actuating means for substantially simultaneously moving each of said holding members of said respective first and third arms between said locked and unlocked positions in response to movement of said respective actuating means between an actuated position and a deactuated position, a first connecting means releasably and rotatably engaged with said second arm by said holding member of said second end of said first arm, said first connecting means being slidable with respect to said second arm, a second connecting means releasably and rotatably engaged with said second arm at an end thereof opposite said first arm by said holding member of said first end of said third arm, said third arm being slidable with respect to said second arm, a third connecting means releasably and rotatably engaged with a first end of said L-shaped arm by said holding member at said second end of said third arm, a fourth connecting means releasably and rotatably engaged with a second end of said L-shaped arm by a clamp disposed at a first end of said fourth arm, said fourth arm including a connection to a positioning member adjacent a second end of said fourth arm, said connection being able to lock said positioning member in a desired position.
Claim 3
Dependent Claim
49 words
A device in combination with an object and a base as claimed in claim 1, wherein the base is of the type having a support rod and said holding member at said first end of said first arm is provided for connection of said device to the support rod.
Claim 4
Dependent Claim
22 words
A device in combination with an object and a base as claimed in claim 2, wherein said base is an operating table.
Claim 5
Dependent Claim
22 words
A device in combination with an object and a base as claimed in claim 3, wherein said positioning member is a headrest.
Claim 6
Dependent Claim
27 words
A device in combination with an object and a base as claimed in claim 2, wherein said first arm is slidable with respect to said support rod.
Claim 7
Dependent Claim
29 words
A device in combination with an object and a base as claimed in claim 2, further comprising a safety mechanism extending between the support rod and said fourth arm.
Claim 8
Dependent Claim
35 words
A device in combination with an object and a base as claimed in claim 6, wherein said safety mechanism is connected to said fourth arm via a ball joint disposed proximate the distal end thereof.
Claim 9
Dependent Claim
42 words
A device in combination with an object and a base as claimed in claim 7, wherein said ball joint includes a ball disposed therein and said ball joint allows the ball disposed therein to rotate freely, thus allowing positioning of said device.
Claim 10
Dependent Claim
63 words
A device in combination with an object and a base as claimed in claim 6, wherein said support rod includes a first rod slidably disposed perpendicular to said first arm, a second rod permanently connected to said base, and a third rod which is slidable with respect to said first rod, said second and third rods being adapted to attach to the base.
Claim 11
Dependent Claim
31 words
A device in combination with an object and a base as claimed in claim 9, wherein said safety mechanism includes a second end through which said first rod is slidably disposed.
Claim 12
Dependent Claim
41 words
A device in combination with an object and a base as claimed in claim 1, wherein said connection to said positioning member at said second end of said fourth arm is a ball joint allowing easy positioning of said positioning member.
