The present disclosure relates generally to stage equipment, and more specifically to trusses used to support appliances, such as video displays.
Video displays and other equipment used for events, such as concerts, plays, or other gatherings, may be held on trusses. The trusses may be transported to an event location and secured together to form scaffolding for positioning the equipment relative to a stage, for example. The size and weight of the equipment attached to these trusses presents design challenges to their positioning and operation.
The present application discloses one or more of the features recited in the appended claims and/or the following features which, alone or in any combination, may comprise patentable subject matter.
An appliance-support system in accordance with the present disclosure includes a truss and a positioning system coupled to the truss. The positioning system is adapted to support an appliance, such as a video display, light, speaker, or other device used during stage performances or events.
In illustrative embodiments, the positioning system includes a track extending along a length of the truss and a carriage coupled to the track. The carriage is movable along the track at the selection of a user. The carriage includes a body and a spindle coupled to the body. The body is engaged with the track to support the spindle and allow lateral adjustment relative to the truss along the track. The spindle allows adjustment of an attached appliance toward and away from the track.
These and other features of the present disclosure will become more apparent from the following description of the illustrative embodiments.
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.
An illustrative appliance-support system 10 in accordance with the present disclosure is shown in
One illustrative embodiment of a carriage 18 in accordance with the present disclosure is shown in
Spindle 44 includes an adjustment bolt 41 coupled to a block 43 inside body 42, and a hanger 49 coupled to adjustment bolt 41 outside body 42 as shown in
Hanger 49 is configured to support a shackle 90 (shown in phantom) used to attach an appliance to carriage 18 as suggested in
Track 16 includes a pair of rails 34, 36, and carriage 18 extends between and is supported by rails 34, 36 as shown in
While the disclosure has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as exemplary and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
