Description

April 2, 1940. M. LIEBMANN v BLANKET FASTENER Filed Oct. 7, 1939 INVENTOR flzoses [2225mm TORNEYS Patented Apr, 2, 1940 UNITED-,- STATES PATENT OFFICE BLANKET FASTENER :Moses Liebmann, New York, N. Y. I Application time; 7, 1999, Serial No. 298,416: 1 Claim. (01. 24-725) This invention relates .to clamping means for holding blankets, sheets or bedclothes in place against a mattress, an example of such a device being disclosed in my PatentNo. 2,149,971 dated 6 March 7, 1939. One of the objects of. the present invention is to provide a device which will effectively prevent the blankets from being kicked or thrown'off the bed or otherwise displaced thus leaving the body exposed and unprotected.

10 Another object of the invention is the provision of a clamping device of the character described which is especially adapted for use in connection with mattresses having a rolled top extending along the upper edge of the mattress, the clamp- 15 ing device having means by which the top roll of the mattress is firmly embraced, and having angularly disposed jaws which overlie a portion of the top and side of the mattress and firmly hold portions of the bed covering against the same.

Another object of the invention is to simplify the structure or. the above mentioned patent, by constructing the entireclamp from a single section of spring metal, whereby the manufacturing 25 cost is greatly reduced and economy in production is secured; wherein also the size of projecting elements is reduced and a more effective spring clamping action of the jaws on the roll top of the mattress is attained.

More particularly, the invention contemplates the provision of a single section of spring sheet metal formed with a substantially cylindrical springportion which fits over and closely conforms to the cross-sectional shape of the roll 35 formed on the edge of the mattress, and a pair of the entire clamp is actually produced from a sin- I gle piece of metal.

In the accompanying drawing, wherein several illustrative embodiments of the invention are shown, Fig; 1 is an end view of the clamp in position on the roll top of a mattress, the roll top of. the mattress and a portion of a blanket extending thereover being shown in. section;.Fig. 2 is a plan view of the clamping device; Fig. 3 is 55 a section view on the line 3-3 of Fig. 2, looking in thendirection of .the arrows; and Fig. 4 is "a sectional view through a modified construction. With reference to the structure shown in Figs. 1 to 3 inclusive, l0 indicates the rolled edge of a mattress I, said rolled edge being usually formed 5 along the top of the mattress and it extends completely around the same. superposed upon the mattress in the conventional way is a blanket, sheet, quilt or other bedclothing indicated at l2 which may be securely and neatly held in position over the mattress by means of a plurality; of clamping devices 13, one of which is shownin the drawing. v

The clamping device I3 is preferably formed from a single section of springy, resilient sheet metal and it includes a substantially cylindrical spring section I! from which. extends a pair of angularly projecting jaws M, which are shown in their normal closed position in Fig. 3. The tendency of the cylindrical springportion is to force said jaws toward one another so that in their normal closed position the jaws contact only at the points where they join with the cylindrical spring portion. As seen in Fig. 2, the jaws are longer than the spring portion I! and thus when the clamp is placed in position over the rolled edge of a mattress, they overlie a considerable portion of the rolled edge and hold the bed clothing closely against the'side and top of the mattress, as clearly shown in Fig. 1'. The free ends or edges of the jaws are turned outwardly, as indicated at l5 to provide stiffening flanges which not only add stifiness and rigidity to the jaws, but also provide smooth edges thereon which cannot possibly cut into and damage 36 the bed clothing or the mattress.

To permit the clamp to be readily placed on and off the mattress, I provide finger-engaging lugs I6 which are formed by being cut out of the body of the cylindrical spring portion and then 40 forced outwardly or radially so that they may be easily gripped between the fingers of the hands, as indicated in dotted lines in Fig. 1, and moved in the direction of the arrows therein shown, to spread the jaws apart. In use it will be noted 5 that the jaws l4 rest flatwise against the top and side respectively of the mattress and hold the blanket l2 thereagainst. It will also be noted that while these jaws press the blanket'firmly against the top and side of the mattressthey have'no parts tending to penetrate, cut or bite into the blanket or mattress so that the possibility of causing damage thereto is wholly avoided.

It will be additionally noted that the entire clamp is made from a single section of sheet metal so that its manufacturing cost is negligible, and that due to its unitary construction it conforms closely in shape to the portion of the mattress which it embraces and lacks the projecting elements often found in prior devices which render them difiicult to place on and remove, and which often scratch or otherwise damage the bed.

In the modified structure shown in Fig. 4, finger-engaging projections l3 are shown which are made slightly longer than those indicated at IS in Figs. 1 to 3 inclusive. The projections or lugs l8 are doubled back as indicated at I!) so that they may be moved toward one another by being compressed by the fingers of one hand, whereby manipulation of the clamp is somewhat simplified.

It will be understood that the device may be made of any suitable material, shape and size to suit various requirements and that one or more of the devices may be employed at the edge of the mattress according to the requirements necessary to hold the bed covering securely and neatly in position.

What I claim is:

A device for holding bed clothing to the rolled edge of a mattress comprising, a clamp having a cylindrical spring portion, the ends of said portion being bent laterally and sharply angularly to form a pair of fiat faced jaws, said jaws extending angularly with respect to one another and being normally distended away from one another at their outer ends, said jaws having their outer edges bent sharply angularly to the plane of th jaws to provide stiffening flanges along said edges, said jaws being longer than the cylindrical spring portion and. being formed integrally with the cylindrical portion and being respectively adapted to overlie the top and side of a mattress, and finger-engaging lugs cut out of the cylindrical portion for manually moving the jaws away from one another against the tension of the cylindrical portion.
