15 Claims. (Cl. 5-345) The present invention relates to a novel handle structure, and more particularly to a novel handle structure of the type adapted to be applied to an article for lifting purposes.

The present invention contemplates a handle structure which is especially suitable for application to a portion of a workpiece made from fabric or other pierceable material, and while many uses for the structure of the present invention may suggest themselves it will be described with particular reference to its use in connection with a mattress or similar workpiece in order to facilitate the disclosure.

As will be understood, mattress structures are usually provided with edge or peripheral cover strips formed from one or more pieces of fabric or ticking and frequently including a layer of felt padding or the like. Handle devices have heretofore been secured to such peripheral covering strips for the purpose of facilitating lifting or maneuvering of the mattress, and considerable difficulty has been encountered in providing a handle device which may be easily and economically manufactured and applied to the peripheral cover strip and which is also sufficiently rugged and durable to be commercially acceptable. Therefore it is an important object of the present invnetion to provide a novel, rugged and durable handle structure which may be economically manufactured and which may be easily and securely fastened to a workpiece formed from fabric and the like such as a peripheral cover of a mattress.

A more specific object of the present invention is to provide novel fastening or securing means for a handle structure of the above described type, which fastening means may have a portion integrally connected to a handle element of the handle structure. Another specific object of the present invention is to provide a handle structure of the above described type having novel fastening or securing means provided separately from but easily connectable to a separate handle element of the handle structure.

A further object of the present invention is to provide a novel handle structure of the type mentioned in the preceding paragraphs wherein the fastening means may be constructed so as to provide breather openings for permitting ventilation of the interior of a workpiece such as a mattress.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:

Referring now more specifically to the drawings wherein like parts are designated by the same numerals throughout the various figures, a handle structure 2t) incorporating one embodiment of the present invention is shown in Figs. 1-4. The handle structure is adapted to be applied to peripheral cover means 22 of a mattress 24. While the cover means 22 may be formed in accordance with various known practices, the cover means shown for the purpose of illustration herein is provided by a quilted assembly of outer and inner fabric strips 26 and 28 retaining a layer of padding material 30 therebetween.

The handle structure 20 is provided by an elongated handle element 32 which is adapted to have its opposite ends connected to the peripheral cover means 22 by identical fastening devices 34. Each of the fastening devices 34 is provided with a plastic body member 36 having a generally fiat end surface 38 adapted to be placed against the outer side or surface of the cover means 22. The opposite end of the plastic body 36 is formed with a recess 40 so as to provide an axially extending flange 42 and a recessed end surface 44 well within the terminal free end of the annular flange 42. Annularly spaced relatively small apertures 46 extend through the body member 36 and generally parallel to its axis, which apertures are spaced around a circle having a diameter only slightly less than the internal diameter of the flange 42 for the purpose described below. It is important to note that in this embodiment the handle element 32 is formed of plastic material and the plastic body members 36 of each of the fastening def vices are integrally connected to opposite ends of the 50 which has an internalgdiameter similar to the internal diameter of the flange 42 of the plastic body member. A plurality of integrally connected prongs 52 is provided for connecting the body member 36 of each fastening device to its associated member 48. In this embodiment the prongs S2 are integrally connected with each other by means of a head member S4 having a diameter slightly less than the internal diameter of the plastic flange 42. The prongs 52 are adapted to be inserted through the apertures 46, and the prongs are provided with pointed ends so that they may readily pierce the fabric workpiece or cover means 22. As shown best in Figs. 2 and 4, the length or axial extent of the prongs 52 is suiiicient to enable entering end portions of the prongs to pass entirely through the assembly provided by the plastic body 36, the cover means 22 and the member 48, which entering end portions 56 may then be bent by suitable die means, not shown, so as to extend around and back along the iiange 5@ for securely and positively connecting the parts together. It will be appreciated that the member 54 and prongs 52 may be easily and economically formed from sheet material such as steel. The prongs are provided with a generally rectangular transverse cross sectional shape which is similar to the generally rectangular transverse f cross sectional shape or" the apertures 46 through the plastic body member 36. However, the transverse dimensions of the prongs 52 are initially slightly greater than the corresponding transverse dimensions ot the apertures 46 so as to insure a tight tit between the prongs and the plastic body member.

Fig. 5 shows a handle structure Which is similar to the structure described above as indicated by the application of identical reference numerals with the suix a added to corresponding elements. In this embodiment the handle element 32a is formed separately from the plastic body members 36a of the fastening devices 34a of which only one is shown. The handle member 32a is formed from a suitable fabric material. The handle member 32a is adapted to be pierced by the prongs 52a as indicated in Fig. 5 so that it is clamped between the body member 36a and the member 54a. Thus it will be appreciated that the handle member may be easily and securely connected to the fastening devices at the same time the fastening devices are applied to the cover means 22a.

Figs. 6, 7 and 8 show another embodiment of the present invention which is similar to the structures described above as indicated by the application of identical reference numerals with the suiiix b added to corresponding elements. In this embodiment the head member 5411 is provided with a central opening defined by an axially extending short flange 60. in addition, the head `member is curved or dome-shaped and is provided with The a plurality of annularly arranged apertures 62. plastic body member 36b is provided with a central aperture 64 and axially extending slots 66' radiating from the aperture 64. The aperture 64- and the slots respectively register with the central opening and annularly arranged apertures in the head member 54h so as to provide vent opening means for permitting ventilation of the interior of a workpiece such as a mattress through the fastening device.

Fig. 9 shows another modified form of the present invention which is similar to the devices described above as indicated by the application of identical reference numerals with the snif); c added to corresponding elements. In this embodiment the prongs 52e are integrally joined to the member 48e at the inner side of the fabric cover means 22C. means in much the same manner as the devices described above except that the prongs are pressed through the fabric cover means from the inner surface thereof and then through the apertures or slots 46c in the plastic body member 36e. End portions 56e of the prongs are This device is secured to the cover Llli then bent so as to overly the outwardly facing surface 44C of the plastic body member. In this embodiment the surface 44C is dome-shaped and a complementary dome-shaped sheet material member 54C is inserted into the recess in the plastic body member with a force tit for overlying the inwardly turned ends of the prongs. The member 54C positively restrains the ends of the prongs against being reversely bent so as to preclude any possibility of the fastening device coming apart.

Fig. l0 shows a device similar to those described above as indicated by the application of identical reference numerals with the suftix d added to corresponding parts. This embodiment utilizes prongs 52d which are integral with the inner member 48d in much the same manner as the embodiment shown in Fig. 9. However, in this device the outer surface 44d of the plastic member is planar and the ends 56d of the prongs are reversely bent for biting into the plastic body member securely to fasten the parts together.

In Figs. 11 through 13 there is shown another embodiment of the present invention which is similar to the structures described above as indicated by the application of identical reference numerals with the sufx e added to corresponding elements. In this embodiment the apertures 46e have a triangular cross sectional shape While the prongs 52e have a rectangular shape. As a result, the apertures 46 will provide vent openings even when the prongs are forced or wedged into the apertures as shown in Figs. 12 and 13. This manner of providing vent openings is especially advantageous when a head member 54e having numerous small perforations 62e therethrough is provided. It is also to be noted that in this embodiment the washer-like member 48e is substantially at or in other words has inner and outer margins of substantially the same thickness whereby it may be more readily fed through a coined changing mechanism, not shown, to a position for assembly with the remainder of the parts.

Fig. 14 shows a structure essentially similar to that described above as indicated by the application of identical reference numerals with the suiiix f added to corresponding elements. In this embodiment the washerlike member 487 is provided with an internal axially extending ilange Stlf for cooperating with ends of the prongs 527. The washer 4Sf is also provided with an outer peripheral axially extending ange 70 of the same length as the flange 502 This washer-like member like the member 48e has substantially uniform inner and outer marginal thicknesses so that it may be more readily fed to a position for assembly with the remaining parts.

Fig. l5 shows a slightly modified plastic handle member 32g which may be used in place of any of the plastic handle members in the embodiments described above. The handle member 32g differs in that it is provided with generally rounded beads 72 and 74 along its opposite longitudinal margins, which beads have relatively small sections 76 and 7S extending upwardly or outwardly from a central web section 80. Relatively large rounded portions 82 and 84 of the beads proiect downwardly or inwardly from the central web section of the handle member. These beads increase the strength and ruggedness of the handle member and also provide rounded surfaces for promoting the comfort of a user during lifting or handling of a mattress.
