Object holding device

Claim 1

An object holding device for removably attaching a main object to an accessory object where either the main object or the accessory object has a pillar-shaped portion comprising: an annular clamping band being put on the pillar-shaped portion of one of the two objects; a holder having one end which is joined with the other object and the other end which is pushed against the pillar-shaped portion through the annular clamping band, the one end of the holder having a cylindrical hollow with a bottom, a centerhole of the bottom being made through the bottom, a surface of the bottom having one or plural convex planes, one or plural concave planes, and one or plural inclined planes which are arranged in a given order; a disk which is put rotatably in the cylindrical hollow, the disk having an operating lever, a surface of the disk having one or plural convex planes, one or plural concave planes, and one or plural inclined planes which are arranged in such a manner that the surface of the disk engages the surface of the bottom; and a headed connecting bolt having a screw head brought into contact with the disk and having a shank passing through the disk and the holder, the end of said shank being joined with the annular clamping band.

Claim 3

A device for attaching an object having a pillar to a frame, comprising: (a) a stretchable band having a circumferential surface adapted to encircle the pillar; (b) a holder having a base with a curvature conforming with a surface of the pillar, and having a face containing a hollow at its end opposite the base and remote from the pillar; (i) said hollow having a base containing a group of surfaces arranged angularly around the center of said hollow, one of which is convex, another concave, and another inclined and located between the convex and concave surfaces; (ii) said holder having a central axis passing through its said face and the center of the hollow and intersecting the circumferential surface of the band; (c) means for attaching the holder to the frame; (d) a disk fitted into said hollow, (iii) said disk having a face juxtaposed to the base of the hollow, said disk face having a group of surfaces arranged angularly around the center of the disk, one of which is concave, another convex, and another inclined and located between the concave and convex surfaces; (e) means connecting the disk face to the band and holding the disk face against the base of the hollow; (f) a lever arm extending laterally from the disk by which the disk may be rotated on said axis relative to the holder; (g) a pair of stop surfaces spaced angularly apart from each other in the path of movement of the lever and positioned so that when the lever engages one of the stop surfaces the convex surfaces of the holder and the disk are in contact with each other and the concave surfaces of the disk and holder are substantially separated, thereby stretching the band and tightening it against the pillar, and when the lever engages the other of the stop surfaces, the convex surface of the disk is close to, or contacts, the concave surface of the holder, thereby relaxing the band and permitting removal of the pillar from the band.

Claim 4

A device for attaching an object having a pillar to a frame, comprising: (a) a stretchable band having a circumferential surface adapted to encircle the pillar; (b) a holder having a base with a curvature conforming with a surface of the pillar, and having a face containing a hollow at its end opposite the base and remote from the pillar; (i) said hollow having a base containing a group of surfaces arranged angularly around the center of said hollow, one of which is convex, another concave, and another inclined and located between the convex and concave surfaces; (ii) said holder having a central axis passing through its said face and the center of the hollow and intersecting the circumferential surface of the band; (c) means for attaching the holder to the frame; (d) a disk fitted into said hollow, (iii) said disk having a face juxtaposed to the base of the hollow, said disk face having a group of surfaces arranged angularly around the center of the disk, one of which is concave, another convex, and another inclined and located between the concave and convex surfaces; (e) means connecting the disk face to the band and holding the disk face against the base of the hollow; (f) a lever arm extending laterally from the disk by which the disk may be rotated on said axis relative to the holder; (g) a pair of stop surfaces spaced angularly apart from each other in the path of movement of the lever and positioned so that when the lever engages one of the stop surfaces the convex surfaces of the holder and the disk are in contact with each other and the concave surfaces of the disk and holder are substantially separated, thereby stretching the band and tightening it against the pillar, and when the lever engages the other of the stop surfaces, the convex surface of the disk is close to, or contacts, the concave surface of the holder, thereby relaxing the band and permitting removal of the pillar from the band.
