Abstract
Abstract A hinged binder assembly for a plurality of stacked planar plates or cards 11 on which rug samples 10 are mounted. Each card is laterally inserted and held at one end in a generally rectangular rail member 12, 27 having circular passages 23, 24; 33, 34 in respective rear and front walls thereof. U-shaped stirrups 19, 29 are inserted into and hingedly connect the rail members together from both sides such that one arm of each stirrup extends into a rear wall passage of one rail member while its opposite arm extends into a front wall passage of the rail member lying immediately above in the binder "closed" position. The connecting webs 20, 30 of each stirrup thus extend at an inclined angle between adjacent rail members. With this arrangement the sample bearing cards can be turned over one at a time in the manner of book pages, or pulled out in a translational manner into a partially overlapping stepped configuration wherein portions of all samples are exposed for viewing.

Total Claims: 10
Claim 1
Independent Claim
213 words
A hinged binder assembly for a plurality of stacked planar cards on which rug samples or the like may be mounted, and including a plurality of generally rectangular, hollow rail members individually receiving and holding one end of a sample card, with said rail members lying adjacent to and one above the other when the binder assembly is in a closed position, comprising: (a) cylindrical lateral channels defined in and extending through respective front and rear walls of each rail member, (b) a plurality of U-shaped stirrups each including a pair of parallel cylindrical arms and a connecting web, and (c) a pair of stirrups being connectingly disposed on opposite sides of each adjacent set of upper and lower rail members with one arm of each stirrup rotatably engaged in a rear wall channel of a lower rail member and the other arm rotatably engaged in a front wall channel of an upper rail member, with the web of each stirrup thus lying at an inclined angle between adjacent rail members, (d) whereby the sample bearing cards may be turned over one at a time in the manner of book pages, or pulled out in a translational manner into a partially overlapping stepped configuration wherein portions of all samples are exposed for viewing.

Claim 3
Dependent Claim
29 words
An assembly according to claim 1, wherein the channels are accessible through slots in the front and rear walls, whereby the stirrup arms may be snap-engaged in the channels.
Claim 4
Dependent Claim
25 words
An assembly according to claim 1, wherein the rail members are movable into the "stepped" position by displacement along a circular arc of approximately 180°.
Claim 5
Dependent Claim
21 words
An assembly according to claim 3, further comprising means for preventing the stirrups from moving axially relative to the rail members.
Claim 6
Dependent Claim
21 words
An assembly according to claim 4, wherein the stirrups are anchored in the rail members by thickened collars on the arms.
Claim 7
Dependent Claim
24 words
An assembly according to claim 5 wherein the rail member channels have transverse grooves in which the thickened collars on the arms positively engage.
Claim 8
Dependent Claim
21 words
An assembly according to claim 6, wherein the arms of the stirrups narrow towards their ends to terminate in pointed ends.
Claim 9
Dependent Claim
27 words
An assembly according to claim 1, wherein the outside surfaces of the front and rear walls of the rail members are in the shape of circular arcs.
Claim 10
Dependent Claim
32 words
An assembly according to claim 1, wherein a connecting rail is disposed below the lowest rail member, rests on a bottom book cover, and is releasably secured thereto by a resilient tongue.
