Abstract

Abstract Transport securing device for a record player, the base plate of which rests with the interposition of elastic support elements on a mounting plate, having a spacer which is arranged movably on the base plate and protrudes below the lower edge of the base plate and, within a thread, bears a screw an enlarged foot part of which engages below the mounting plate while its head extends above the base plate and is so provided with a collar that, upon unscrewing, it clamps the base plate as well as the mounting plate separately but at the same time between itself and the spacer, the base plate not changing its position with respect to the mounting plate.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 315 words
A transportation securing device for a turntable, the base plate of which when in operating condition rests, with the interposition of elastic support elements, on a mounting plate, comprising a spacer member arranged substantially below the base plate of the turntable, said spacer member has a lower part and a top part, said lower part is formed with a female thread and has a bottom side projecting downwardly past a lower edge of said base plate, said spacer member including on said top part thereof upper projections which extend non-rotatably through said base plate of the turntable and rest loosely thereon, said base plate is formed with a bore, a screw seated in said female thread of the spacer member and extending upwardly through said bore formed in the base plate, a lower collar on said screw being larger in diameter than said bore in the base plate of the turntable and lies therebelow, and upon screwing up said screw said lower collar clamps the base plate between said lower collar and said upper projections of said spacer member, a foot part fastened on a lower end of said screw, said mounting plate is formed with a laterally open recess, said recess is smaller in diameter than that of said foot part, said screw is tiltably mounted on the base plate of the turntable, being swingable into and out of said laterally open recess in the mounting plate, said foot part being disposed below the mounting plate, said mounting plate is clampable between said bottom side of said spacer member and said foot part of said screw by said screwing up of said screw, said foot part of said screw is arranged at such a distance from said lower collar of said screw that upon said screwing up of said screw, said base plate of the turntable and the mounting plate are simultaneously clamped fast.
Claim 2
Dependent Claim 315 words
A transportation securing device for a turntable, the base plate of which when in operating condition rests, with the interposition of elastic support elements, on a mounting plate, comprising a spacer member arranged substantially below the base plate of the turntable, said spacer member has a lower part and a top part, said lower part is formed with a female thread and has a bottom side projecting downwardly past a lower edge of said base plate, said spacer member including on said top part thereof upper projections which extend non-rotatably through said base plate of the turntable and rest loosely thereon, said base plate is formed with a bore, a screw seated in said female thread of the spacer member and extending upwardly through said bore formed in the base plate, a lower collar on said screw being larger in diameter than said bore in the base plate of the turntable and lies therebelow, and upon screwing up said screw said lower collar clamps the base plate between said lower collar and said upper projections of said spacer member, a foot part fastened on a lower end of said screw, said mounting plate is formed with a laterally open recess, said recess is smaller in diameter than that of said foot part, said screw is tiltably mounted on the base plate of the turntable, being swingable into and out of said laterally open recess in the mounting plate, said foot part being disposed below the mounting plate, said mounting plate is clampable between said bottom side of said spacer member and said foot part of said screw by said screwing up of said screw, said foot part of said screw is arranged at such a distance from said lower collar of said screw that upon said screwing up of said screw, said base plate of the turntable and the mounting plate are simultaneously clamped fast.
Claim 3
Dependent Claim 37 words
The transportation securing device according to claim 1, further comprising elastic means arranged on a top side of said foot part for elastic application of said foot part against the mounting plate when brought into clamping position.
Claim 4
Dependent Claim 95 words
The transportation securing device according to claim 1, further comprising longitudinal guide means in said base plate of the turntable for vertical displacement of the spacer member in an upward direction, an upper collar disposed on said screw above the base plate of the turntable, arranged at such a distance from said lower collar of said screw that upon screwing down and unscrewing of said screw, said upper collar rests against said base plate such that further turning of the screw causes lifting of said spacer member off from said base plate of the turntable.
Claim 5
Dependent Claim 29 words
The transportation securing device according to claim 3, wherein said guide means constitute openings formed in said base plate through which said upper projections of said spacer member extends.
Claim 6
Dependent Claim 48 words
The transportation securing device according to claim 4, wherein said openings each have a widened insert portion and an operative narrowed portion, said upper projections have a top flange extending laterally wider than said narrowed portion, said widened insert portion is wider than that of said top flange.
