ill. 15. 9/5/6535 United States Patent 3,205,547 DEVICE FOR ATTACHING FABRIC 0R SIMILAR MATERIAL TO SUPPORT Neil B. Riekse, Detroit, Mich. (3853 Legion Lane, Los Angeles, Calif.) Filed June 22, 1962, Ser. No. 204,564 2'Clai1us. (Cl. 24-243) This invention relates to a device for securing a sheet of fabric, plastic or other deformable material to a supporting surface, preferably in sealed relation therewith, so that the sheet material can be removed whenever desired.
A few of the many possible uses of the device include the sealing of one edge of a shower curtain to a wall of a tub enclosure, the mounting of panels of plastic material for storm windows or other enclosures, and the mounting of protective covers for objects of various kinds.
The general object of the invention is to provide a device which will secure a sheet of deformable material in sealed but removable relation to a supporting surface; which will not injure the material; and which can be readily and easily installed.
A device constructed in accordance with the invention consists of a pair of members, one of which is formed of resilient material with a longitudinally extending recess and with a slot communicating with the recess, the width of the slot being less than that of the recess. The other member includes a recess engaging portion having a width greater than the slot but less than that of the recess so that this portion of the other member can be placed in contact with the sheet of material to be secured and forced through the slot into the recess of the first member thereby retaining the material therein. One of the members is provided with suitable means whereby it may be secured to a supporting surface, preferably in sealed relation therewith.
In the preferred construction to be described herein, one of the pair of members acts as a base member and is provided with a recess having the shape of an equilateral triangle in cross-section, and a base surface adapted to be secured to the supporting surface. One apex of the triangular recess points toward the base surface and the side of the triangular section opposite this one apex is approximately parallel to the base surface. A slot is formed in this opposite side of the triangular recess communicating therewith but having a width less than the recess side so as to form an inwardly facing shoulder on each side of the slot. The slot side walls are tapered and resilient so that they may be spread apart. The other member is an insert member consisting of a strip of non-resilient material having an equilateral triangular cross-section but of area less than that of the triangular recess. This insert member is engageable with the strip of material to be secured and can be forced through the slot and into the recess. During this operation the triangular shape of the insert member functions to spread the resilient sides of the slot apart and, when in the recess, the insert member and material are engaged in interlocked but removable relation with the base member, particularly the inwardly facing shoulders thereof.
Other features and advantages of the construction will appear from the following detailed description of the presently preferred embodiment thereof disclosed in the accompanying drawings which include the following views:

FIGURE 3, an enlarged sectional detail taken as indicated by the line 3-3 of FIG. 1 showing the parts in ex ploded relation; and
FIGURE 4, a view similar to FIG. 3 showing the parts assembled.
A conventional tub installation includes a wall 10 at the head end of the tub 12 on which a shower head 14 and shower curtain rod 16 are mounted. When the shower is operated difliculty is usually experienced in positioning the shower curtain 18 so that water does not escape between the curtain and the wall 10 at the head end of the tub. This difficulty can be effectively prevented by employing the device 20 of the present invention to removably secure the shower curtain to the wall 10 in sealed relation therewith.
The construction and operation of the device are shown in detail in FIGS. 3 and 4. It consists of a pair of members 22 and 24, which for convenience will be referred to as a base member and an insert member respectively. Base member 22 is formed of extruded relatively resilient plastic material and is provided with a base surface 26 and a longitudinally extending recess 28 with an outwardly facing slot 30 communicating therewith, the slot having a transverse dimension less than that of the recess. The other or insert member 24 has a transverse dimension greater than that of the slot 30 but less than that of the recess 28 so that the insert member can be engaged with the sheet of deformable material, namely the shower curtain 18, adjacent one edge 32 thereof, and forced through the slot into the recess thereby retaining the curtain 18 therein.
In the preferred construction shown the recess 28 in the base member 22 has the cross-sectional shape of an equilateral triangle, the apex 34 of which is located adjacent the base surface 26, forming a pair of inwardly converging sidewalls 37 and 38. The leg of the triangle opposite the apex 34 extends substantially parallel to the base surface 26 and the slot 30 is formed therein, the slot having a width less than the length of the side of the triangle so as to form a pair of inwardly facing shoulders 40 and 41 on each side of the slot 30. Slot 30 is also provided with inwardly converging sidewalls 42 and 43.
Insert member 24 is also formed with a cross-sectional configuration of an equilateral triangle having an area less than that of the recess 28 but with each side of the triangle having a length greater than the width of the slot 30 and preferably a slightly concave portion 44. When the triangular insert member is placed in engagement with the shower curtain 18 and forced into the recess 28, the converging faces 46 and 47 of the insert member act to spread the sides of the slot 30 apart. Due to the resilience of the base member 22, the curtain 18 is not injured but yet is securely retained in sealed relation with the base member. Whenever it is desired to remove the curtain, it is relatively easy to withdraw the insert member from engagement in the recess. If desired, one end 50 (FIG. 2) of the insert may be allowed to project from the adjacent end 51 of the base memher and this projecting end of the insert can be grasped and pulled away from the base member, gradually spreading the slot of the base member progressively along its length and withdrawing the insert member from engagement in the recess.
Foolproof assembly of the two members is insured by the equilateral triangular shape of the recess and insert member.
Pressure sensitive adhesive means 52 are preferably employed for securing the base surface 26 of the base member 22 to the supporting surface 10.
The construction illustrated is intended as representative, since the two members of the device may be changed in construction and proportion to suit the particular material to be mounted, and obviously, if desired, either of the pair of members cantbe employed as a base memberin other words,reither can be provided with means Which enable it to be secured to the supporting surface. Therefore such modifications from the construction illustrated as are within the scope of the following claims are to be considered a part of the present invention.
1. A device for removably securing a sheet of deformable material such as fabric or plastic to a supporting surface comprising a base member of resilient material having a base surface adapted to be secured to said supporting surface, a longitudinally extending recess formed in said base member, said recess having a sectional configuration of an equilateral triangle with one apex thereof extending toward said base surface and with the side opposite said'one apex extending parallel to said base surface, a continuous slot communicating with said recess along the side opposite said one apex, said slot having v the width of said slot whereby the sheet of material to be secured'can be wrapped around at least one apex of the insert member and said one apex inserted in the slot, the insert member serving as a wedge to spread the side walls of the slot when the insert member and material are pushed through the slot into the recess and into overlapping engagement with saidinwardly facing shoulders, and means for securing the base member to said supporting surface.
2. A device as claimed in claim 1 wherein the insert member is made of a flexible material.
