Description
March 30, 1 R, A. CRAMER MOLDING FOR CHAIR BACKS OR THE LIKE Filed April 12, 1951 IN V EN TOR.
ATTORE 5 I Patented Mar. 30, 1954 MOLDING FOR CHAIR BACKS OR THE LIKE Roy A. Cramer, Kansas City, Mo., assignoi' to Cramer Posture Chair 00., Inc., Kansas City, Mo., a corporation of Missouri Application April 12, 1951, Serial No. 220,690
This invention relates to a molding or bumper strip and is particularly adaptable for the back of a chair, automobile seat or other devices requiring a covering and molding or trimming at the juncture of two surface portions.
Heretofore in the construction of an upholstered office chair or the like, it has been the usual practice to draw the upholstering of the back about a cushion member and then over the edges to the rear side of a cushion support plate and fastening the same. An outer plate is usually fastened to the back side of the support plate. As the chair or other article is used, the upholstering wears against the supporting plate, due to contact with other oflice fixtures and also to the normal slipping strain when in use, and the back plate with its clamping action tends to wear the upholstering material.
It is, therefore, the principal objects of the present invention to obviate these undesirable features; to proside a molding and bumper for the edges of the decks of chairs or the like having a supporting plate and clamping plate with a resilient member for engagement of the upholstering material and a second resilient member for engaging the edges of the clamping plate to engage the upholstering and retain the same in non-slipping relation to the first resilient member thereby providing a cushioning effect; to provide a device of this character for preventing marring of furniture, walls and the like with which a chair comes in contact and to prevent wear of the edges of the upholstery of the chair; to provide a device of this character which will prevent chipping or marring of the enamel on the back plate of a chair or the like; and to provide a device of this character, simple, economical to manufacture and eflicient in operation.
In accomplishing these and other objects of the invention as hereinafter pointed out, I have provided improved details of structure, the preferredform of which is illustrated in the accompanying drawings, wherein:
Fig. 1 is a fragmentary cross sectional view of a part of a chair or the like having a supporting plate and clamping plate particularly illustrating my molding structure.
Fig. 2 is a vertical cross sectional elevational view through my device.
Fig. 3 is a fragmentary view showing the inner -molding or bumper member.
Fig. 4 is a fragmentary cross sectional view of the outer molding or bumper member.
Referring more in detail to the drawings:
1 Claim. (Cl. 155-184) While my invention may be adapted to various articles of furniture, automobile seats and the like, I will describe the same in relation to a chair back or the like.
I designates the back of a chair having a supporting plate 2 to which is attached a resilient cushion member 3 usually made of sponge or foam rubber or the like. The supporting plate 2 is provided with a plurality of threaded bore openings 4 adapted to receive the threaded shank 5 of screws or the like 6 for retaining a clamping plate.| on the supporting member. lhe clamping plate is substantially of the same size as the supporting plate and each is provided with peripheral edges 8 and 9, respectively.
member I3 is provided of substantially triangular shape with the outer or upper portion roundas indicated at I5. One of the angle shaped sides is provided with a groove or slot I6 adapted to engage the periphery of the edge 8 of the clamping plate I as best illustrated in Fig. 2. The bumper members In and I3 are preferably made of rubber, plastic or other resilient material.
The cushion member 3 is provided with a covering or upholstery material [1, such as fabric or the like, having its free edges hemmed providing a loop l8, through which a fastening device l9, such as cord, wire or the like, is drawn for tightening the upholstery as is the usual practice. The upholstering material is drawn over the side of the wounded portion I! of the molding or bumper Ill and lies alongside of the face 20 thereof, the loop I8 extending slightly below the lower edge of the bumper. The side face 2| of the bumper l3 engages against the outer edge of the upholstering material with its point l5 engaging the loop portion so that the upholstery material lies between the two bumper members as best illustrated in Fig. 2, and thus retain the upholstering material between the bumpers and prevent its slipping or becoming loose. The clamping plate I is then secured'to the supporting plate by the screws-6. The pressure of the edge 8 of the plate I on the bumper l3 against the bumper l0 prevents the bumper l3 from becoming loose and pulled out until the plate I is released.
The sides of the angle shaped bumper l3 are substantially flat or plane and the slot l6 extends inwardly at substantially a right angle on the outer side as illustrated in Fig. 2, so that the outer edge of the clamping plate presses the opposite side of the bumper against the other bumper at the upper edge thereof, and thus allows flexing of the inner bumper to prevent wearing of the rubber and material.
It will be obvious from the foregoing that I have provided an improved bumper or molding for chairs or other articles which will securely hold the upholstery to the'back of the chair and prevent wearing thereof and which will prevent marring of furniture, walls or the like due to contact of the chair with such objects and also a device which may be readily assembled and disassembled when necessary to change the upholstering material.
What I claim and desire to secure by Letters Patent is:
A back structure for a chair or the like comprising, a supporting plate and a clamping plate having peripheral edges, a cushion member on the supporting plate, a rubber member having a slot for engaging the peripheral edge of the sup-porting plate, the sides of said rubber member vJeing tapered upwardly and terminating in a rounded upper edge and the sides having substantially plane surfaces, an upholstering materia1 covering the cushion member and extending over the outermost plane surface of said rubber member, means on the edge of the upholstering material for securing same to the supporting plate, a substantially V-shaped rubber member having two substantially plane surfaces and a rounded upper surface, one of said plane surfaces having a slot engaging the peripheral edge of the clamping plate and the other plane surface being substantially coextensive with and engaging the upholstering material extending over the plane surface of the first rubber member, said last named slot extending inwardly of said plane surface at an angle toward the upper edge of the opposite plane surface of said member so that the last named plane surface lies flat against the plane surface of the first rubber member, the point of the V- shaped rubber member engaging the upholstering securing means to prevent the material from being withdrawn from between the two rubber members, and means securing the clamping plate to the supporting plate, said clamping plate being of substantially the same size as the supporting plate and having its center portion spaced therefrom and its outer portion turned inwardly at an angle to exert pressure of the V-shaped rubber member against the rubber member on the supporting plate.
ROY A. CRAMER.
