Abstract
Abstract A fastening device for securing together two adjoining structures, such as two building or wall panels which have adjoining edges abutting each other. In the adjoining edges the panels are provided with recesses, one of which has a cross bar constituting a part of the fastening means. In the other recess there is movably carried a hook adapted to extend across the juncture of the panels for engagement with the cross bar to latch onto the same. The swivel portion of the hook is formed in the shape of a large eye or bearing ring, in which there is located an operating disk having bearings in the opposite side walls of the recess which carries the hook. The disk is eccentrically mounted in such a manner that when it turns it will effect an advancing and retracting movement of the hook, and will also effect a rotary movement or excursion of the hook into or out of the adjoining recess of the other panel. The eccentric disk is of molded plastic and has an integral flange constituting a track and stop shoulder formation which is engageable with portions of the hook to effect the proper movements and positioning of the latter The molded disk has means engageable by a tool, such as a square or hexagonal section key, for the purpose of turning the disk so as to operate the hook for fastening or unfastening the panels.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
251 words
A hook-type tensile fastening device for securing together two adjoining structures comprising, in combination: a. a base member, b. a resilient, hook member constituted of round metal wire and having substantially the configuration of the FIG. ''''6'''', c. said hook member including at one end a bent, substantially circular bearing portion of relatively large diameter, including at its other end a bent bill portion, and including a connector portion extending between said bearing and bill portions, d. the bends at the bill and bearing portions being in the same general directions and towards each other, e. a one-piece, molded plastic disk disposed in the bearing portion of the hook member and turnable therein, and f. means eccentrically mounting the disk on the base for turning movement thereon about an axis parallel to and non-coincidental with the axis of the disk, g. said disk having a circular flange integral with and extending along peripheral portions of the disk at one side thereof, h. the flange of the disk having a circular guide portion on and integral with it and engageable with outer areas of the bearing portion of the hook member, said circular guide portion being spaced from the periphery of the disk and forming therewith an annular groove having a mouth at the other side of the disk, through which the circular bearing portion of the hook member can be passed, i. said circular bearing portion riding in said groove when the disk is turned with respect to the hook member.

Claim 3
Dependent Claim
30 words
A fastener as in claim 1, wherein: a. the circular guide portion has stop shoulders adapted to engage opposite sides of the hook member to effect a driving connection thereto.
Claim 4
Dependent Claim
33 words
A fastener as in claim 1, wherein: a. the disk has detent shoulder means integral therewith, engageable with the bearing portion of the hook member to retain said bearing portion on the disk.
Claim 5
Dependent Claim
38 words
A fastener as in claim 3, wherein: a. the circular guide portion of the flange has detent shoulder means integral therewith, engageable with the bearing portion of the hook member to retain said bearing portion on the disk.
Claim 6
Dependent Claim
48 words
A fastener as in claim 1 and further including: a. a retainer plate secured to the other side of the disk and extending beyond peripheral portions of the disk, b. said retainer plate overlying the circular bearing portion of the hook to retain the same on the disk.
Claim 7
Dependent Claim
27 words
A fastener as in claim 1, wherein: a. the circular guide portion of the disk has undercut walls, producing a groove whose mouth is of reduced width.
Claim 8
Dependent Claim
