DECK CHAIR CANVAS Nov. 29, 1955 2 Sheets-Sheet 2 Filed Dec. 9, 1953 INVENTOR. MELVILLE GRANBY United StatesPatentO DECK CHAIR CANVAS 'Melville Granby, Cincinnati, Ohio Application December 9, 1953, Serial No. 397,204
3 Claims. (Cl. 155187) This invention relates to a snap-on type deck chair canvas, and to the method of making same.
An object of the invention is to provide a snap-on type deck chair canvas for attachment to the frame elements of a deck chair.
Another object of the invention is to provide lengths of flexible deck chair canvas with snap fasteners for enabling the opposite ends thereof to be secured in loopfashion to and around a support or frame element for thereby securely though detachably anchoring the ends of the canvas to the support element.
A further object of the invention is to provide ;the ends of deck chair canvas with rows of laterally spaced separable snap-on fasteners, for enabling the canvas to be readily secured to and/or quickly detached from the frame elements of a deck chair. By using my deck chair canvas it is now but a simple task to replace the worn canvas of deck chair assemblies by attaching new canvas to the frame elements of the chair assembly, by
merely connecting the separable portions of'snap type fasteners.
Still a. further object of the invention is to provide a snap-on type deck chair canvas having the hereinabove described characteristics wherein the snap fasteners are secured to the canvas in such a manner as to preclude said fastener elements from touching the body of a person seated in a deck chair provided with canvas embodying the teachings of the present invention.
Another object of the invention is to provide a deck chair canvas the ends of which are provided with separable snap fasteners which are rendered invisible when the canvas has been attached to the frame elements of a deck chair.
Still another object of the invention is to provide a method of anchoring the respective portions of separable fasteners relative to the ends of a deck chair canvas.
A further object of the invention is to provide canvas attachment means in the form of separable snap fasteners which are so constructed and so arranged relative to the canvas as to preclude their being accidentally or unintentionally separated after having been connected.
These and other objects are attained by the means described herein and as disclosed in the accompanying drawings, in which:
Fig. l is a perspective view of the rear of a typical deck chair provided with snap-on type canvas strips embodying the teachings of the present invention.
Fig. 2 is a perspective view of the front of the chair of Fig. 1.
Fig. 3 is an enlarged fragmentary view of the lower end of the chair back as seen in Fig. 1.
Fig. 4 is a view similar to Fig. 3 showing the relationship of the variousparts when a load has been applied to the back and seat panels of the chair.
Fig. 5 is a sectional view taken on line 55 of Fig. 4.
Fig. 6 is a sectional view similar to Fig. 5 but illustrating the fasteners in separated position.
Fig. 7 is an enlarged fragmentary view of the lower right corner of Fig. 3 showing the snap fastener portions in separated position.
Fig. 8 is a sectional view taken on line 8-8 of Fig. 1.
At the outset it should be clearly understood that the present invention has been illustrated in connection with the canvas strips of a conventional or typical deck chair, however such relationship is exemplary rather than restrictive in nature, since the present invention is equally adapted to the canvas strips for any type of chairlike structure having pairs of parallel supporting elements to which the ends of canvas strips are adapted to be secured.
With particular reference now to Figs. 1 and 2, the numerals 10, 12 and 14 denote generally three canvas strips the opposite ends of each of which are secured to parallel support or frame elements 11, 13, 15, 17, 19, 21 and 23, respectively.
Heretofore it has been customary to secure the ends of canvas strips relative to their respective frame elements by first tacking the ends of the strips directly to the frame elements and of then wrapping the canvas around the frame elements for securely anchoring the end thereof to the frame element. This mode of attachment rendered it most difiicult, if not impossible, for owners of deck chairs, and the like, to remove the canvas strips for purposes of cleaning, storage and/or replacement.
Another manner in which the ends of canvas strips have heretofore been anchored to the frame elements of deck chairs has been to provide a permanently closed loop or hem in the ends of the canvas strips for the reception of the structural elements of the deck chair. Quite obviously canvas strips thus secured to the structural elements of a chair could not be removed without at least partially disassembling the chair in order that the support elements could be removed from the permanently closed loops in the end of the canvas strips.
The primary object of the present invention is to provide strips of canvas the ends of which are provided with snap-type separable fasteners which when fastened will provide a closed loop in the ends of'the strip, thereby facilitating attachment of the canvas strips to the frame elements of adeck chair. The invention likewise comprehends the particular manner in which the separable elements or portions which collectively comprise the snap fasteners are secured to the ends of the canvas strips whereby they will not become separated incident to the application of loads to the said strips. The invention further comprehends the mounting of the component parts of separable snap fasteners to the flexible canvas strips or panels in such a manner as to enable'them to be easily opened or separated, without requiring the use of special tools, incident to the application of an opening pressure applied in a particular quadrant of the snap fasteners.
With particular reference now to Figs. 5, 6 and 8, the numeral 20 denotes the front face and the numeral 22 the rear face of canvas strip 10.
A row of the socket-portions 30 of each of a plurality of snap-type separable fasteners are secured directly to and along the end of the canvas strip with the open part of the socket portion facing outwardly of the rear face 22. In the preferred embodiment of the invention the socket portions 30 extend through the canvas strip and through a reinforcing strip which may, if desired, be formed by folding the end of the strip upon itself as at 40, thence back upon itself as at 42, for thereby providing a reinforced edge, note Fig. 6.
The stud portions 50 of the snap fasteners are secured directly to a reinforcing or carrier strip denoted generally by the numeral 52, said strip preferably comprising four plies of material which may, if desired, be similar to the material from which strips 10, 12 and 14 are fabricated.
Carrier strip 52.is permanently fastened vto rear.face..22
in spaced parallelism with the, end 54 of the canvas strip such as by means of stitching denoted generally by the numerals '56. As clearly" evident from an inspection of Figs;i5', 6 and 8; no partiof the socket portions extends through or is visible through frOnt face Zt) of jthe'canv as l With particular reference now to Fig. 3, the broken lines XYZdefine'aquadrant of thesocket portion 30-of the fastener elements, which is so" constructed'and arranged as to effectively "resist lateral'separatlon'except in response to the' applieation'of opposing axial forces In by a line normal ,to the forces applied to the connected portions of the fasteners by a loadsupported on the front face of the canvas strip. The dot within the apex of quadrant X-YZ oflFig. 3 is on a line which bisects said quadrant, said dot indicating the center thereof.
The use of separable fasteners secured to the ends of canvas strips provides quick, easy means for securely anchoring the ends of the strips relative to the frame elements of a chair whereby accidental or unintentional separation of the fastener portions'is positively precluded incident to the application of loads onto the canvas strips since, as a matter of fact, the greater the load applied to the canvas strips, the greater will be the force by which the respective socket and stud portions of the individual fasteners are locked together.
The canvas strips may be quickly removed from the chair frame incident to application of a lifting force applied to the socket portions 30 within the quadrant defined, in Fig.3, by the lines X-Y-Z.
From the foregoing, it will be noted that I have provided simple yet highly effective means for enabling a canvas strip to be quickly securedto and removed from a chair frame by means of separable snap fasteners secured to the ends of the strips as heretofore indicated.
