BINDING MEANS FOR THE SURFACE COVERINGS OF FURNITURE.

Application filed August 28, 1924. Serial No.734,777.

This invention relates to improvements in binding means which are used to protect and secure the edges of surface or cover sheets for desks, tables and other articles of furniture, such as the sheets of linoleum orthe like commonly used to cover the tops of nected in such manner as to make it diflicult to apply or fit the binding device or members, requiring very exact work in production and if a slight imperfection or inaccuracy occurred, thestructure could not be assembled, and no opportunity was allowed for 'slight adjustments to overcome such inaccuracies.

One of the objects of the present invention is to construct an improved binding structure for the surface covering sheets, of articles of furniture so that the binding strip or member may be readily and accurately fitted to suit the conditions of the article of furnie ture and cover sheet and so that the side portions or edges of the coveredparts are exposed and accessible to enable this to be done before the binding device is completely assembled. Other objects are to provide a structure of this sort in which a fixed part of the article of furniture is provided with a holding portion cooperating with a holding part on the binding strip to retain the strip in place against structure has been assembled; also to provide a detachable clamping and retaining member adapted to be attached to the rigid top member or part of the article of furniture in such a way that when secured in place it will engage and force the binding strip or member inwardly firmly against the edge of the cover sheet and at the same time securely clamp the strip between said clamping member and the edge of said top or part, and-alsoto im-' prove structures ofthis sort in the other respects hereinafter specified and claimed. In the accompanying drawings, I Fig. 1 is a perspective view of a corner of nintentional displacement after the.

A metal top plate of a desk or other article of furniture is shown at 10, and 11 represents a cover sheet or plate of linoleum or other sultable material which is secured thereon and forms the top surface of the desk or other top. The top plate 10 is provided at'each exposed edge thereof with an integral depending marginalflange lQ and an inwardly directed horizontal flange 13 formed at the lower edge of the flange 12 and extending beneath the top plate 10. 15 represents a bind ing or securingand protectin strip or member preferably stamped from .ronze or other suitablemetal, and whichis adapted to lie JAMESTOWN, NEW YORK, 'ASSIGNOR TO ART METAL CONSTRUC- against orengage a portion of the outer face v of the depending flange 12 of the-top plate 10 and is provided at one edge with the inwardly extending overhanging lip 16 adapted to engage theedge of the cover sheet 11. I

Except as disclosed in Figs. 5 and 6, a separate, detachable securing member 20 is provided which is adapted to be secured to the rigid marginal flange or part'of the top plate 10 and engages the binding strip 15 and forces the lip 16 tightly against the ed e of the cover sheet 11, and clamps the b0 y of the strip firmly against the marginal flange 12 of the top plate. This securing member 20, in the two constructions shown in Figs. 1 l to i and 7 is formed of a sheet metal section havinga substantially horizontal'attaching flange QIad'a-pted to engage and be removably secured to the under side of the inturned flange 13 of the top, and a vertical flange 22 extending upwardly therefrom so as to engage the outer face of the blndi'ng strip. The member 20 may be releasably secured to the flange 13 in any suitable manner but is preferably secured by screws 23 which pass through holes 24 in the attaching flange 21 and enter threaded holes 25 in the flange 13.

As clearly shown in Figs. 2, 4 and 7 the angle between the attaching flange 21 and the vertical flange 22 of the securing member is slightly less than 90, so that the flange 21, instead of extending parallel w th the flange 13 engages it at a distance inwardly from the face of the flange 12. The securlng member 20 thus fulcrums on the flange 13, so that, when the screws 23 are tightened, the top edge of the vertical flange 22 is moved inwardly towards the binding memberv15. The member 20 will therefore be pressed or forced tightly against and clamp the bind1ng strip 15 securely in place and provide a firm engagement of the lip 16 against-the edge of the cover sheet 11. Figs. 2 and 4 clearly 1llustrate this action by the relativepositions of the binding strip 1-5 and secunng member 20. l

Means are provided in the construction il-' lustrate'd in Figs. 1-4, and 7 whereby the binding strip is maintained in fixed relation to the top plate and is prevented from edgewise movement between the flange 12 and securing member 20. For this purpose as shown in Figs. 2 to 4, the marginal flange 12 of the top plate is formed or provided between its upper and lower edges with an 1nwar'dly. extending or underc-ut shoulder 28 and the binding strip 15 is provided with an integral narrow flange 29 which extends inwardly from its lower edge and is adapted to engage under the shoulder 28. The flange 29 preferably extends upwardly at a slight angle or at an'acute angle to the body of the strip so that its outer edge only engages the shoulder 28 inwardly beyond the-outer face of the flange 12, andthe binding strip is further provided with an outwardly ofl'set bead or portion integral with the upper lip 16 which forms a shoulder 30 adapted to overhang and be engaged by the top edge of the upright flange 22 of the securing member so that as the securing screws 23 are tightened up, the slight upward movement of the flange 22 raises the binding strip and draws its flange '29 tightly against the shoulder 28 and also tends to swing the upper edge or lip 16 informs the shoulder 28 wardly, tight against the cover sheet 11. In

the construction shown in Figs, 2 to 4, the shoulder 28 is pressed orrolled directly in the flange 12, while in the modified form illus trated in Fig 7, the flange 12 of the top 10 terminates a short distance below the top and and a separate angle strip 31 having an offset inclined portion 32 member and a bottom flange 13 is rigidly secured to the inner wall of the flange 12 as by spotwelding or otherwise. In other respects this construction is similar to the first construction.

The described construction -of the binding or securing and protecting means providing a separate binding strip/with a lip adapted to interlock with a shoulder on the rigid-top, and a separate detachable securing strip adapted to be secured to the rigid top and forced inwardly by its securing devices, provides a strong, durable and firm construction adapted to firmly engage and hold the edge of .the cover sheet in place. Also the provision of the separate securing member enables the binding strip to be fitted and adjusted to the particular conditions of the top plate and cover sheet, as the side edges of the top are unobstructed and accessible. After the binding strip has been fitted, the securing member is positioned and attached by the screws to the lower flange 13 and by tightening these screws the securing member is pressed tightly and forcibly against the bind ing strip at the upper portions of the member and strip. The binding strip is then held firmly between the flanges 12 and 17 and is maintained from edgewise movement or dis engagement by the engagement of the flange 29 with the shoulder .28 and the shoulder 30 with the upper edge of the flange 22.

securely hold the binding strip 15 in place and maintain its lips 16 in firm engagement the covering sheet 11 while V the screws 23 are tightened, it nevertheless wit-h the edge of permits the ready removal of the binding strip when desired, by simply loosening the screws 23. The member 20 does not have to bedetached from the flange 13 asthe loosening of the screws permits the flange 22 of the to fall away from the edge of the top member sufliciently to free the binding strip flange 29 from beneath the shoulder 28. i

The modified construction shown in Figs. 5 and 6 provides an inexpensive but desirable structure. In this form instead of the, separate binding strip 15 and clamping strip 20 before described, a single piece combined securing and binding strip or-member' is substituted, in the form of an angle bar 32 having a bottom securing flange 33 adapted to be attached to the flange 13 by screws 23 as before, and having an upright side flange 34 which -1s provided with an inturned lip 35 at its upper edge adapted to While the securing member 20 is adapted to 2 The flange 33 extends upwardly and inwardly at a slight angle as in the other con-. struction described, and the tightening of the screws 23 forces the lip'35 inwardly tightly binding means is preferably formed of continuous strips for the

parts

15 and 20 which are bent on arcs of short radius at the corners, and the two ends of each strip abut between two of the corners, for instance on the back edge of the desk top. Should the corners of the article be square the binding means would be applied in the form of separate strips for each edge, with the ends of the strips mitered and abutting,
