Abstract

A support head for a support rod which enables the angular orientation and the longitudinal position of the rod to be adjusted with respect to the support head. The support head includes a main body supported on a stand, an intermediate member and beyond the intermediate member a finishing member. The main body and intermediate member have facing annular ridged racks which when engaged prohibit relative rotation therebetween. A screw connection between the main body and the intermediate member is tightened to prohibit rotation and is loosened to permit it. The intermediate member and a finishing member beyond it have respective cooperating recesses which together define an opening through which the support rod is passed and is longitudinally movable. A second screw connection between the finishing member and the intermediate member is tightened to clamp the rod in the recesses and is loosened to permit the rod to be shifted longitudinally.

Claims

1. A support head for a support rod, comprising:

a main body, an intermediate member adjacent the main body and a finishing member adjacent the intermediate member;

the main body and intermediate members having respective facing first sides;

first engaging means on the facing first sides for preventing relative rotation of the intermediate member with respect to the main body when the main body and intermediate member have been moved together to bring the first engaging means into engagement;

first attaching means between the main body and the intermediate member for supporting the intermediate member to enable relative rotation of the intermediate member with respect to the main body when the first engaging means are out of engagement and for drawing the main body and the intermediate member together for bringing the first engaging means into engagement and prohibiting further relative rotation of the main body with respect to the intermediate member;

the intermediate member having a first rod holding recess facing the finishing member;

the finishing member having a second recess placed for cooperating with the first recess of the intermediate member, such that together the first and second recesses define an opening for receiving the support rod therein;

second means for connecting the intermediate member and the finishing member for drawing the finishing member toward the intermediate member, thereby to draw the first and second recesses together for clamping the support rod in the opening defined by the cooperating recesses, and for enabling the intermediate member and the finishing member to be moved apart for moving the recesses apart for releasing the grip upon the support rod;

the support rod being longitudinally movable in the opening defined in the first and second recesses and being movable through the opening generally across the axis of rotation of the intermediate member with respect to the main body.

2. The support head of claim 1, wherein the first attaching means comprises a screw which engages the main body and is threadedly received in the intermediate member for being tightened for drawing the main body and intermediate member together and loosened for permitting the main body and intermediate members to separate.

3. The support head of claim 2, wherein the second connecting means comprises a screw which engages the finishing member and is threadedly received in the intermediate member for being tightened to draw the intermediate and finishing members together and loosened to permit the intermediate and finishing members to be moved apart.

4. The support head of claim 1, wherein the second connecting means comprises a screw which engages the finishing member and is threadedly received in the intermediate member for being tightened to draw the intermediate and finishing members together and loosened to permit the intermediate and finishing members to be moved apart.

5. The support head of claim 2, further comprising a spring normally biasing the main body and intermediate members apart.

6. The support head of claim 4, further comprising a spring normally biasing the intermediate member and the finishing members apart.

7. The support head of claim 5, further comprising a first spring for biasing the main body and intermediate members apart and a second spring for normally biasing the intermediate member and the finishing member apart.

8. The support head of claim 1, wherein the first means for preventing relative rotation of the main body and intermediate member comprises a cooperating first set of radially extending ridges and grooves on the main body and facing toward the intermediate member and a second set of radially extending ridges and grooves on the intermediate member and facing toward the first set of ridges and grooves, for the first and second sets of ridges and grooves to be brought into engagement for preventing relative rotation of the intermediate member and the main body.

9. The support head of claim 1, further comprising support means attached to the holder for supporting the holder to a stand.

10. The support head of claim 9, wherein the support means is attached to and extends radially away from the main body.

11. The support head of claim 1, wherein each of the first and second recesses is generally polygonal in shape and together define the opening of a shape to engage the rod which passes therethrough.

12. The support head of claim 1, wherein the recesses are polygonal in shape and are oriented to cause the opening for the support rod to extend transversely to the axis of rotation of the intermediate member with respect to the main body.

13. The support head of claim 2, wherein the screw for connecting the main body and the intermediate member defines an axis of rotation of the intermediate member with respect to the main body.

14. The support head of claim 3, wherein the screw for connecting the main body and the intermediate member defines an axis of rotation of the intermediate member with respect to the main body;

the first and second screws being coaxially aligned.
