Abstract

A mount that secures a projector to a ceiling is disclosed. The mount includes an upper element which is attached to the ceiling, and a lower element which is attached to the projector. The two elements are adapted to slidably engage and disengage for quick mounting without having to detach the upper element from the ceiling and the lower element from the projector. The mount may include a spring-biased latch which locks the two elements together to prevent accidental disengagement. The latch may include a safety lock feature which prevents inadvertent actuation of the latch and subsequent disengagement of the elements.

Claims

1. An audiovisual projector ceiling mount, comprising:

an upper element adapted for attachment to a ceiling, said upper element having a top surface and a bottom surface, said upper element further including a slide guide projecting from said bottom surface;

a lower element adapted for attachment to a projector, said lower element having a top surface and a bottom surface, said lower element further including a flange projecting from said top surface, said flange being in slidable engagement with said slide guide of said upper element and said flange defining an interior space of said ceiling mount between said flange and said upper element top surface; and

one of said upper and lower elements further including a securement component for maintaining said slidable engagement between said upper element and said lower element, said securement component including a latch disposed in said interior space which engages said other element to maintain the engagement of said upper element and said lower element, said latch further including a hook, and said latch hook further engaging said flange when said upper and lower elements are engaged together.

2. An audiovisual projection ceiling mount as described in claim 1, wherein said upper element includes, the plate having an upper surface for engaging a ceiling component, the plate upper surface constituting said upper element top surface.

3. An audiovisual projector ceiling mount as described in claim 1 wherein said lower element includes a plate having an aperture, said plate and aperture being adapted to supportingly receive a particular projector.

4. An audiovisual projector ceiling mount as defined in claim 3 wherein said lower element further includes a member for adjusting the angle of said plate relative to said upper element.

5. An audiovisual projector ceiling mount as described in claim 1 wherein said latch is a biased latch pivotably coupled to said one of said elements.

6. An audiovisual projector ceiling mount as described in claim 1 wherein said securement component includes a biasing component which urges said latch to maintain said engagement position.

7. An audiovisual projector ceiling mount as described in claim 6 wherein said biasing component includes a spring.

8. An audiovisual projector ceiling mount as defined in claim 1, wherein said securement component includes a biased latch pivotably coupled to said one of said upper and lower elements, said hook being disposed at one end of said latch and said latch having an engagement position at which said latch engages said other element of said upper and lower elements to maintain the engagement of said upper element and said lower element.

9. An audiovisual projector ceiling mount as defined in claim 8 wherein said securement component includes a biasing component which urges said latch to maintain said engagement position.

10. An audiovisual projector ceiling mount as defined in claim 9 wherein said biasing component comprises a spring.

11. An audiovisual projector ceiling mount, comprising:

an upper element adapted for attachment to a ceiling, said upper element having a top surface and a bottom surface, said upper element further including a slide guide protecting from said bottom surface;

a lower element adapted for attachment to a projector, said lower element having a top surface and a bottom surface, said lower element further including a flange projecting from said top surface, said flange being in slidable engagement with said slide guide of said upper element; and

one of said elements further includes a securement component for maintaining said slidable engagement between said upper element and said lower element, said securement component includes a latch which engages said other element to maintain the engagement of said upper element and said lower element, and said latch further includes a member for locking said latch whereby inadvertent actuation of said latch and subsequent unintentional disengagement of said elements is prevented.

12. An audiovisual projector ceiling mount as defined in claim 11 wherein said locking member includes a bolt through said latch to lock it relative to said one of said elements.

13. An audiovisual projector ceiling mount comprising;

an upper element adapted for attachment to a ceiling, said upper element having a top surface and a bottom surface interconnected by two side walls, said upper element further including a slide guide projecting from said bottom surface;

a lower element adapted for attachment to a projector, said lower element having a top surface and a bottom surface, said lower element further including a flange projecting away from said top surface, said flange being in slidable engagement with said slide guide of said upper element when said upper and lower elements are engaged together, said upper and lower elements cooperatively defining, between said upper element bottom surface and said lower element flange, an interior space of said ceiling mount;

one of said elements having a length imparting a low-profile characteristic to the mount, said length being defined by a distance between said top surface of the upper element and said bottom surface of the lower element of said interior space; and

one of said elements further includes a securement component for maintaining said engagement between said upper element and said lower element, said securement component including a hook that engages said lower element flange when said lower and upper elements are engaged together, said hook being disposed within said interior space and intermediate said upper element sidewalls.

14. An audiovisual projector ceiling mount as defined in claim 13 wherein said length imparting said low profile characteristic is not greater than about 10 cm.

15. An audiovisual projector ceiling mount as defined in claim 13, wherein said upper element includes a plate having an upper surface for engaging a ceiling component, said plate upper surface constituting said upper element top surface.

16. An audiovisual projector ceiling mount as defined in claim 13 wherein said lower element includes a plate having an aperture, and said plate and aperture are adapted to supportingly receive a particular projector.

17. An audiovisual projector ceiling mount, comprising:

an upper element for attaching to a ceiling, said upper element having a top surface and a bottom surface interconnected by opposing sidewalls, said upper element further including at least one slide guide projecting from said bottom surface and aligned with an opening formed in said upper element bottom surface;

a lower element for attaching to a projector, said lower element having a top surface and a bottom surface, said lower element further including at least one flange disposed thereon and projecting from said top surface, said slide guide and said flange being in slidable engagement, and said lower element flange being accessible through said upper element opening when said flange is aligned with said slide guide;

one of said upper and lower elements further including a latch member for securing said said upper element and said lower element in engagement with each other; and

said latch member being aligned with said upper element opening and further being manipulatable into engagement with said upper element flange to secure said upper element to said lower element.
