Abstract

Various implementations include a head frame holding device. The device includes a base, a head rest, and at least one head frame holder. The head rest has a first end coupled to the base and a second end spaced apart from the first end. The at least one head frame holder has a first end coupled to the base and a second end spaced apart from the first end. The second end of the at least one head frame holder includes a head frame coupler for coupling the head frame to the device.

Claims (23)

1 . A head frame holding device, the device comprising:

a base;

a head rest having a first end coupled to the base and a second end spaced apart from the first end; and

at least one head frame holder having a first end coupled to the base and a second end spaced apart from the first end, wherein the second end of the at least one head frame holder includes a head frame coupler for coupling a head frame to the device;

wherein the head frame coupler includes at least one head frame clamp coupled to the second end of the at least one head frame holder, wherein the at least one head frame clamp includes a protrusion that is configured to be disposed within a groove of a head frame.

2 . The device of claim 1 , wherein the second end of the head rest includes a chin rest.

3 . The device of claim 2 , wherein the chin rest includes a concave surface facing opposite from the first end of the head rest.

4 . The device of claim 2 , wherein the chin rest includes a cushion.

5 . The device of claim 1 , wherein the second end of the head rest can be moved between a first position to a second position, wherein the second end of the head rest is closer to the first end of the head rest in the first position than in the second position.

6 . The device of claim 5 , wherein the head rest includes a first portion including the first end of the head rest and a second portion including the second end of the head rest, wherein one of the first portion of the head rest or the second portion of the head rest defines a central longitudinal opening, and an other of the second portion of the head rest or first portion of the head rest is slidingly disposed within the central longitudinal opening of the head rest.

7 . The device of claim 6 , wherein the one of the first portion of the head rest or the second portion of the head rest defines one or more side openings, the head rest further including one or more locking pins disposable within the one or more side openings of the head rest to rigidly couple the first portion of the head rest to the second portion of the head rest.

8 . The device of claim 1 , wherein the first end of the head rest is slidingly coupled to the base by a rail and bearing.

9 . The device of claim 1 , wherein the at least one head frame holder includes two head frame holders.

10 . The device of claim 1 , wherein the second end of the at least one head frame holder can be moved between a first position to a second position, wherein the second end of the at least one head frame holder is closer to the first end of the at least one head frame holder in the first position than in the second position.

11 . The device of claim 10 , wherein the at least one head frame holder includes a first portion including the first end of the at least one head frame holder and a second portion including the second end of the at least one head frame holder, wherein one of the first portion of the at least one head frame holder or the second portion of the at least one head frame holder defines a central longitudinal opening, and an other of the second portion of the at least one head frame holder or first portion of the at least one head frame holder is slidingly disposed within the central longitudinal opening of the at least one head frame holder.

12 . The device of claim 11 , wherein the one of the first portion of the at least one head frame holder or the second portion of the at least one head frame holder defines one or more side openings, the at least one head frame holder further including one or more locking pins disposable within the one or more side openings of the at least one head frame holder to rigidly couple the first portion of the at least one head frame holder to the second portion of the at least one head frame holder.

13 . The device of claim 1 , wherein the first end of the at least one head frame holder is slidingly coupled to the base by a rail and bearing.

14 . The device of claim 1 , further comprising at least two legs extending from the base, wherein the at least two legs have a first end coupled to the base and a second end spaced apart from the first end of the at least two legs.

15 . The device of claim 14 , wherein the second end of the at least two legs can be moved between a first position to a second position, wherein the second end of the at least two legs is closer to the first end of the at least two legs in the first position than in the second position.

16 . The device of claim 15 , wherein the at least two legs include a first portion including the first end of the at least two legs and a second portion including the second end of the at least two legs, wherein one of the first portion of the at least two legs or the second portion of the at least two legs defines a central longitudinal opening, and an other of the second portion of the at least two legs or the first portion of the at least two legs is slidingly disposed within the central longitudinal opening of the at least two legs.

17 . The device of claim 16 , wherein the one of the first portion of the at least two legs or the second portion of the at least two legs defines one or more side openings, the of the at least two legs further including one or more locking pins disposable within the one or more side openings of the at least two legs to rigidly couple the first portion of the at least two legs to the second portion of the at least two legs.

18 . The device of claim 14 , wherein the at least two legs each include two or more wheels coupled the second end of each of the at least two legs.

19 . The device of claim 1 , wherein the at least one head frame clamp includes two head frame clamps, wherein the at least one head frame holder includes two head frame holders, wherein each of the two head frame clamps is slidingly coupled to the second end of a different one of the head frame holders such that the head frame clamps can be moved toward and away from each other.
