Abstract

A mobile stand-type loudspeaker set installing device including a movable mounting member slidably mounted on the bottom of a cabinet accommodating a loudspeaker, and a long mounting screw threadably engaged with the movable mounting member. With this device, it is never necessary to drill a mounting hole in a steel plate body member of the vehicle, and hence the loudspeaker set can be readily installed on the vehicle body.

Claims

1. A device for installing a stand-type loudspeaker cabinet to a vehicle body, comprising:

an elongate base arm secured to the bottom of said cabinet and having engagement projections extending longitudinally thereof;

a movable mounting member having substantially U-shaped engaging portions slideably engaged with said engagement projections of said base arm in such a manner as to be movable in the longitudinal direction along said base arm, said mounting member having a threaded opening therein; and

a threaded mounting screw threadedly engaged in said threaded opening of said movable mounting member, one end of said screw extending through said mounting member and engaging said base arm so as to fixedly secure said mounting member thereto and another threaded end of said screw extending away from said base arm such that said another end of said mounting screw provides a means for securing said cabinet to the vehicle body.

2. The installing device of claim 1, wherein said base arm has the form of a dish-shaped plate in cross section and has a substantially U-shaped groove extending along a central longitudinal axis thereof for allowing the slideable movement of said mounting member having said screw engaged therewith.

3. The installing device of claim 2, wherein said base arm is recessed in said bottom of said cabinet.

4. The installing device of claim 3, further comprising a plurality of positioning ribs arranged in a line at predetermined intervals on said recess for receiving said one end of said screw.
