FIG. 2 c, another perspective view of the plunger embodiment of the invention is shown which illustrates the location of thedepressible plunger 215. In an embodiment of the invention, thedepressible plunger 215 is identified for consumer use by labeling the forward facing external side of the plunger assembly with, for example, “Push Here.” The labeling identifies to the consumer the location in which a portion of the fabric sheet is to be pushed into themain body 205 and held against the inner side of the main body by the plunger assembly. - Referring to
FIG. 2 d, another cutaway perspective view of the invention is shown which illustrates aconsumer 275 pressing a portion of afabric sheet 60 into themain body 205 from the exterior side to the interior side. - The counterforce provided by the
spring 220 being compressed against the rearinternal cavity 240 of themain body 205 is sufficient to allow the insertion offabric sheet 60 but will provide a compressive force against thefabric sheet 60 and theinterior rim 250 of themain body 205 when theplunger 215 is released by theconsumer 215. - Referring to
FIG. 3 a, a second plunger embodiment of the invention is provided. In this embodiment of the invention, themain body 305 utilizes a generally open construction having a laterally oriented U-shaped frame which perpendicularly engages theface 230 of themain body 305. This embodiment of the invention is nearly identical to the embodiments described inFIG. 2 with exception of the generally open construction. - This embodiment of the invention is useful for traditional coil and spring and/or other non-foam core constructed
bedding articles 70. This embodiment of the invention provides a metal frame 360 which is attached 325 a, 325 b to the internal frame of thebedding article 70 during manufacturing. The metal frame 360 includes one ormore openings 320 a, 320 b dimensioned to receive the main body 304. Once the bedding articles are completely assembled, theopenings 320 a, 320 b for installing the device(s) are cut into the padding and the fabric sheet retaining device inventions are inserted into theopenings 320 a, 320 b and metal frame 360. The number of retaining devices used per corner of thebedding article 70 may be one or two depending on the thickness of the bedding article. - Referring to
FIG. 3 b, an example usage is shown where aconsumer 275 pushes a portion of thefabric sheet 60 into the device by depressing theplunger 215. This action causes thedepressible plunger 215 to move backwards sufficiently to allow a portion of thefabric sheet 60 to become captured between the front of theplunger 215 and the interior rim 340 (FIG. 3 c) of themain body 305. - Referring to
FIG. 3 c, a rear prospective view of the invention is shown which illustrates the internal frame housing thedepressible plunger 215, thecounterforce spring 220,internal rim 340 andtravel slot 235. Themain body 305, including the internal frame housing anddepressible plunger 215 is constructed of plastic materials using an injection molding process. The plastic should preferably be made of polymers having fire retardant or slow burning characteristics. In addition, for durability, high impact plastics are preferred. - Referring to
FIG. 3 d, another rear prospective view of the invention is shown which illustrates the interaction of thefabric sheet 60 is inserted into theaperture 335 from the exterior side to the interior side. Theaperture 335 is formed between theplunger 215 andinternal rim 340 when theplunger 215 is depressed. - The
counterforce spring 220 provides the necessary counterforce to compressively retain thefabric sheet 60 against theinternal rim 340 once the consumer 275 (FIG. 3 b) releases theplunger 215. In an embodiment of the invention, thelateral extension 225 extends through thetravel slot 235 provided when theplunger 215 is depressed. One skilled in the art will appreciate that other compressive arrangements which do not require thetravel slot 235 may be used as well. - Referring to
FIG. 4 a, an example implementation of the plug embodiment of the invention is shown installed on abedding article 70. A consumer 275 (FIG. 3 b) inserts 400A a portion of thefabric sheet 60 from the exterior side of themain body 5 to the interior side into theaperture 35 of themain body 5, places theplug 25 into theaperture 35 such that theclasp 30 is aligned with the long dimension of theaperture 35, and then twists 65 theplug 25 to engage the twist lock feature. The twist lock feature compresses the retained portion of thefabric sheet 60 against the forward face of theclasp 30 and theinner rim 50 of themain body 5. Removal of thefabric sheet 60 is accomplished simply by reversing the twist lock feature and pulling thefabric sheet 60 free of themain body 5. - Referring to
FIG. 4 b, an example implementation of the plunger embodiment of the invention is shown. In this embodiment of the invention, a consumer 275 (FIG. 3 b) inserts 400 b a portion of thefabric sheet 60 from the exterior side of themain body 305 to the interior side into the aperture 335 (FIG. 3 d) of themain body 305 while concurrently depressing theplunger 215. Once a sufficient portion of thefabric sheet 60 has been placed into the aperture 335 (FIG. 3 d), the consumer 275 (FIG. 3 b) releases thedepressible plunger 215, which allows the spring 220 (FIG. 3 d) counterforce to compressively retain thefabric sheet 60 against the inner rim 340 (FIG. 3 d) of themain body 305 and the forward face of theplunger 215. Removal of the sheet is accomplished simply by pushing in on thedepressible plunger 215 and pulling thefabric sheet 60 free of themain body 215. - The foregoing described embodiments of the invention are provided as illustrations and descriptions. They are not intended to limit the invention to precise form described. In particular, it is contemplated that functional implementation of the invention described herein may be constructed in various shapes and of different materials. No specific limitation is intended to a particular shape or construction material. Other variations and embodiments are possible in light of above teachings, and it is not intended that this Detailed Description limit the scope of invention, but rather by the claims following herein.
