Abstract
A copy holder is provided with a document holding stand supported adjustably by a support structure to provide a stable support while allowing operator controlled, incremental adjustment through a working range to vary the angle at which the document holding stand is supported. The adjustable support structure is provided by spring clutches on either end of a shaft which can be releasably held in housings attached to the document holding stand and these points of attachment together with a back leg provide for stable support with the incremental adjustment effected by releasing the spring clutch to adjust the gripping position on the shaft relative to the point of attachment for the back leg.
Claims18
A copy holder comprising a document holding stand and an adjustable support means to provide stable support for said document holding stand, said adjustable support means including a pivotal support means to allow pivotal movement between said document holding stand and said adjustable support means, a clutch means in operative engagement with said pivotal support means to hold said document holding stand in position and hand actuated control operating means to act upon and release said clutch means enabling an operator within a working range to select the angle at which the document holding stand is supported and upon such selection release of said hand actuated control means will cause the clutch means to reengage retaining said document holding stand in the selected position.
A copy holder comprising:
- a document holding stand;
- and
- an adjustable support device, said adjustable support device including:
- a back support to provide stable support for said document holding stand, said back support being pivotable relative to said document holding stand;
- a clutch which is operable to restrain pivotal movement between said back support and said document holding stand;
- and
- a hand actuated clutch operating device operable to release said clutch enabling an operator within a working range to select an angle at which said document holding stand is supported by said back support and whereby, upon such selection, release of said hand actuated clutch operating device causes said clutch to re-engage, thereby retaining said document holding stand in the selected position.
An adjustable support device for supporting a member, said adjustable support device comprising:
- two spaced apart housings adapted to support the member, each of said housings having a lower end;
- a shaft extending between and rotationally engaged in both said housings;
- a back support extending rearwardly from said shaft and being mounted to said shaft for pivotal movement with rotational movement of said shaft, said back support having a back end spaced transversely from said shaft;
- a clutch which is operable to enable or restrain rotational movement of said shaft relative to said housings;
- and
- a hand actuated clutch operating device operable to release said clutch;
- wherein, in use, said lower end of said housings and said back end of said back support create a stable support, and an angle between said back support and said housings can be incrementally adjusted by using said hand actuated clutch operating device to release said clutch, rotating said housings relative to said shaft, and releasing said hand actuated clutch operating device to re-engage said shaft with said clutch.
A copy holder comprising:
- a document holding stand having a back surface;
- a shaft rotatably mounted adjacent to said back surface of said document holding stand;
- a back support coupled with said shaft such that said back support pivots as said shaft rotates;
- a clutch operably connected to said shaft so as to selectively restrain rotation of said shaft;
- and
- a hand actuated clutch operating device operably connected to said clutch, said clutch operating device being selectively movable between a first position wherein said clutch engages said shaft to restrain rotation thereof and a second position wherein said clutch at least partially releases said shaft to enable selective rotation of said shaft.
