RETAINING SUPPORT FOR FLEXIBLE THIN-SHEET MATERIALS Filed April 18, 1955 a INVENTOR. JOHN T. DANELL RETAINING SUPPORT FDR FLEXIBLE THIN-SHEET MATERIALS Generally speaking, the present invention pertains to the drapery-hanging and allied arts, and more particularly pertains to a device for grippingly retaining and supporting a flexible thin-sheet member in a virtually vertical depending relationship with respect to weightbearing means, as in hanging draperies, cloth to be dried, and the like, on hooks, shower-curtains, curtain-rods, traverses, clotheslines and similar weight-bearing memhers.
I am aware that many devices, temporarily and permanently attachable to thin-sheet members to support them, have been previously invented and developed. However, all such prior supports, known to me, have suffered from numerous disadvantages. Temporary attachments of the clothespin or spring-grip type fail under heavy loads; the thin-sheet member pulls out of engagement under the force of its own weight. More permanent attachments, such as the rings and pins used with draperies or the rings set into the fabric or plastic of shower-curtains, tend to tear the thin-sheet member when their small area of contact with said member is subjected to stress from weight or from being suddenly pulled to one side in use. The positions of such permanent attachments on thin-sheet members can be changed only with difficulty, and not without leaving marks on said members of the previous attachment positions.
With the above points in mind, an object of the present invention is to provide a retaining support adapted to removably grasp flexible thin-sheet materials, and adapted to be hung from auxiliary weight-bearing means.
.It is a further object to provide a device, as provided in the preceding object, in which downward force on a thin-sheet material increases the force engaging it with said device.
It is also an object of the present invention to provide a device, as provided in the preceding objects, which is adapted for slidable engagement with an auxiliary longitudinal weight-bearing member.
Other and allied objects of the present invention will be apparent to those skilled in the art after a careful perusal of the present specification, the accompanying illustrations, and the appended claim.
To facilitate understanding, reference will be made to the hereinbelow-described drawings, in which:
Fig. l is a side elevation of a preferred form of the device of the present invention, shown in normal or use position with wedge and recess means fully engaged;
Fig. 2 is a front elevation of the device of Fig. 1;

"as indicated at 16 in Figs. 31an'd 4. The recess- A is.
atented June 10, 1958 2 a longitudinal weight-bearing member (not indicated in Fig. 3);
. Fig. 6 shows portions of a modified form of the device of the preceding figures, in disassembled form; similar parts are numbered similarly, but with primed numbers; Fig. 7 shows a front elevation of portions. of the device of Fig. 6 with a thin-sheet member engaged therewith; and Fig. 8 shows the cross-section of the device of Fig. 6 indicated by the line and arrows VIII-VIII of Fig. 7.
The illustrated devices are constructed oftransparent material such as synthetic resin (e. g. Lucite acrylic resin) to make clear the configuration of the devices in the elevational and perspective views; although the surface characteristics, strength, and (in the engaging means) flexibility of such material as Lucite make it suitable for constructing my device, it is not intended that the construction be limited to transparent material or to synthetic resin: metal, wood,'or other materials may be used singly or in combination.
The auxiliary elements, namely the thin-sheet member and the weight-bearing member, have been indicated with broken lines.
The device of the present invention is usable for hanging a thin-sheet member of flexible material (such as fabric, plastic film, and the like) as is indicated at 1,
from weigh-bearing means such as the longitudinal weight-bearing member indicated at 2. Cooperating with sa d weight-bearing member is the engaging means 3, consisting of a loop. It constructed of a rigid material and as nearly closed as is shown, this loop is equivalent to a closed ring; if constructed of flexible material, it can have the member 2 forced through its opening. The form illustrated may obviously have either characteristic. If the loop 3 is used with a smaller-diameter weight-bearing member than that shown, it is equivalent to a hook.
From the loop 3 depends the tensile portion 4, which in the. illustrated form is an extension of the wedge means In the illustrated form the body means consists of two side portions 6a and 6b, mounted on a back portion 7 and laterally spaced by recess means as indicated generally at A. The recess A has a top opening positioned at the top .of the recess A as indicated at 14 in Fig. 4, a bottom openingpositioned atlthe bottom of the recess A as indicated at 15 in Fig; 4, and a front opening positioned at the front of the recess A bounded by the first thin-sheet-engaging surface, consisting of the back surface portion 8 and the side surface portions 9a and 9b (which converge toward the top and front). Note that above point B the surface portions 9a and 9b are cut away slightly to reduce stress on the thin-sheet member. The wedge 5 has a corresponding back surface'portion 1t) and side surface portions 11a and 11b.
In Fig. 4, the device is shown disassembled, ready for use: note the clearance between the tensile means 4 (or, the top of the wedge 5) and the walls of the recess. The thinsheet member 1 is then introduced into recess A, the wedge is pressed against said member 1, and the tensile means pulled up until thin-sheet member 1 is gripped, .as shown in Figs. 3 and 5, and the loop 3 is hung on weight-bearing member 2.
The device of Figs. 1 through 5 has been found especially suited for hanging a shower-curtain from a rod. The device of Figs. 6 through 8 is more suited for hanging fabrics, being provided with friction-increasing or cloth-engaging serrations as at 12, and having a configu ration suited for more bulky materials. The engaging means (not shown) may also take a different (and appropriate) form from that of Figs. 1 through 5: a strong hook or loop of one of the numerous configurations wellknown in the art may be used. Note the stress-reducing angle of the surface portions 9'11 and 9b at point B.
The rear surface 13' of the body means may receive ornamentation if desired; it is exposed to view when in use, although the front surface is-hidden by the member 1. To use the device of the present invention, one places a portion of a flexible thin-sheet member infront of said front opening, places-'saidtensile means (or the narrow upper part of the wedge means) in front of the thin-sheet member against said opening, presses said portion of the thin-sheet member and said wedge means through the bottom and front openings into the recess means, and pulls said tensile means through said top opening until the wedge means and thin-sheet member are securely gripped by the first thin-sheet engaging surface. The thin sheet member is frictionally engaged with both said first and said second surface means. As it pulls said body means downward with respect to said wedge means, the recess and wedge means become more firmly mated and grip the thin-sheet member more securely. There should be suflicient looseness or tolerance between said first and second surfaces to allow this assembly operation to be readily performed and allow the wedge means to make an effective engagement with the recess means. The en gaging means is then engaged with said weight-bearing means to maintain said thin-sheet member in dependent relationship with respect to said weight-bearing means ina virtually vertical position. To remove the thin-sheet member from its enggagement with my device above sequence of operations is reversed.
Numerous modifications and variations of the present invention will occur. to those skilled in the art after a careful study hereof. All such properly Within the basic spirit and scope of the present invention are intended to be included and comprehended herein as fully as if specifically described, illustrated, and claimed herein.
The exact compositions, configurations, relative positionings and cooperative relationships of the various component parts of the present invention are not critical, and may be modified substantially within the basic teachings, spirit and scope of the present invention.
The embodiment of the present invention specifically described, illustrated and claimed herein is exemplary only, and is not intended to limit the scope of the present invention, which is intended to be interpreted in the light of the prior art and the appended claim only, with due consideration for the doctrine of equivalents.
