10 Claims. (Cl. 354) Matter enclosed in heavy brackets appears in the original patent hut forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.
This invention relates to improvements in covers for mattresses, sofa pillows and the like as well as to a method of making such covers].
An object of my invention is to provide a simple cover which closely follows the contours of a mattress or other article of upholstery of substantially prismatic shape and is positively dustproof at the joints.
Another object of this invention is to provide a cover having means for facilitating the fitting of the cover over the bulky body of a mattress or the like.
A feature of my invention resides in the provision of a cover of the above character with box corners formed by inwardly folded integral flaps which insure a snug fit but will not leave the mattress or other protected article exposed if their stitching or equivalent fastening means should be destroyed by continuous wear and tear. This feature renders the cover particularly suitable for use in hospitals, military installations, hotels or other institutions where repeated replacement of bedding is customary and desirable.
H The cover is particularly suitable for fitting over sharpcornered mattresses or pillows not easily accommodated by seamless cases of conventional design. It may be manufactured of a knitted or woven fabric, a plastic, a plastic-coated fabric or other suitable material to render it dustproof and/or waterproof. The seams are preferably applied internally and are thus hidden from view when the article is fitted over a mattress or'pillow to improve its appearance and to reduce the wear and tear on the threads.
A more particular aspect of the invention resides in a novel formation of transverse edges laterally of the rear closed end of the cover and laterally of the open front or receiving end thereof. The free edges of the panels which surround the receiving aperture are provided with conventional closure means, such as the two halves of a slide fastener, for ready closing or opening of the article. The corners at the receiving end of the cover are formed by spreading the material adjacent each end of the fastener to'a width equaling the thickness of the article, rearwardly folding a triangular portion whose apex is at a respective end of the entrance slot, and completing the formation of a triangular flap by a seam of V-shape preferably running wholly inside the cover. The resulting flap forms a convenient handgrip member for drawing the cover over a large article of upholstery.
The edges at the rear, closed end of the cover are formed by providing an internal triangular pocket adjacent the lateral ends of the rear edge; the length of the vertical pocket mouth equals the thickness of the mattress or pillow, and the pocket is then closed by applying a Re. 24,591 Reissued Jan. 20, 19 59 Fig. 4 is a fragmentary perspective view of the closed receiving end of the finished cover fitted over a mattress;
Fig. 5 is a section taken on line 5-5 in Fig. 4;
Fig. 6 is a perspective view of a semi-finished rear corner of the cover;
Fig. 7 is an inside view of a finished rear corner; and
Fig. 8 is an inside view of one of the box corners at the forward end of the cover.
A semi-finished bag-shaped cover 10 is shown in Fig. 1 as including an upper section. 10a and a lower section 10b. The cover is preferably woven in tubular form, i. e. without a seam along the longitudinal edges 11a and 11b whereby the sections 10a, 10b are integral and originally indistinguishable from eachother, and is closed at its rear edge 11c by an internal seam 12 (best seen in Fig. 7). The front end 11d of the cover is open, the free upper and lower marginal edges of the respective sections 10a, 10b carrying slide-fastener halves 13a, 13b which may be interlaced between stops 13d by a conventional slider 130. 'In forming the vertical edge 14, the portion adjacent the slide-fastener stop 13d is spread to a width equaling the thickness of the article to be protected by the cover, such as a mattress 21, and a short piece 15 of flexible reinforcing material, such as a wrapping cord, is inserted in an internal fold 16 obtained by tucking in the material of the cover and fastening it by a vertical seam 17 (see Figs. 2, 3, 5 and 7 Seam 17 defines a diagonal of a diamond-shaped area (see Fig. 2) Whose two triangular halves 18', 18" are then doubled up by folding around this seam, triangular 18 and short portions of slide-fastener halves 13a, 13b being folded rearwardly around the flexible member 15 to form an inner fiap 18 (Fig. 8) which is held in shape by stitching 19' and 19" Although these stitches preferably do not penetrate the outer cover wall, the outline of triangular flap 18 is visible from'without asedge 14 and joints 20', 20" (see Fig. 4) which define a triangular area 29' on a side panel 29. The side panel 29, an opposite side panel 30 (Fig. 3), a front panel 31 and a rear panel 32 are all formed by marginal portions of cover sections 10a, 10b whose central portions constitute an upper panel 10a and a lower panel 10b, respectively. The two inner flaps 18 can be conveniently grasped by the user in fitting the cover over a mattress 21, as illustrated in Fig. 3; this is accomplished by turning the fastener halves outwardly so that the same will not come into contact with the mattress in the course of this operation. When the cover is closed, the slide-fastener halves 13a, 13b are substantially parallel with and between the upper and lower horizontal edges 21a, 21b of the mattress 21 (see Fig. 4) and the internal flaps 18 are between the mattress and the stops 13d (see Fig. 5), which prevents entry or escape of dust even if the slider is not drawn all the way to the stop.
The rear end of the cover is illustrated in Figs. 6 and 7. The material is first spread to a width substantially equaling the thickness of the mattress and is then folded inwardly to form a triangular pocket 22 whose adjacent vertical edges 23 are subsequently joined by an internal seam 24. The resulting rear flap 15 is similar to front flap 18 and defines a triangle whose base, along seam 24, forms one of the vertical edges 26 of the mattress cover.
g In use, the cover closely follows the contours of the mattress as the front flaps '18 are attached to the side panels 29, 30 and the rear flaps 25 are hidden in the cover. It will heseen that ,the apex 28 of each triangular front flap 18, formed by one of the two common front corners of cover halves 10a ,and 11th, extends outwardly from triangle base '17 whereas the apex 27 .of .each rear flap 25, formed by one of the two comm'onrear corners of the cover halves, is. directed inwardly from the corresponding base .24. As .a result of this difference, flap 18 requires stitching 19, 19" on the sides while flap 25 does not. ,Seam ,17 only servestoretain .the reinforcing member and is not .essentialto the continuity .of the structure, hence tension may be exerted upon flaps 18, as when pulling thetcpverover .thefmattress, without risk of damage to the fabric. It will also be noted that flaps 13 help [to relieve any .undnestrain upon slide fastener ;13.
The" seams of my improved cover, whether hidden or not, might yield nponprolonged use but will still leave the mattress ,21 or other protected article unexposed since the material of the cover below the seams is only folded and will thus full-y cover the article. The flexible member 15 may be omitted in covers for sofa pillows or other relatively small articles since its primary purpose is to facilitate the fitting ,of the .cover over bulky mattresses.
The preferred embodiment of my novel cover .has been shown and described for purposes of explanation only and is not to be construed .in a limitative sense, as various changes and modifications will occur to personsskilled in the art within the spirit and scope of my invention defined in the appended claims.
