vvzamej 2,995,795 Patented Aug. 15, 1961 2,995,795 PROTECTIVE CLIP Martin Samson, Samson Products Co., 2601 W. Armitage Ave., Chicago, Ill. Filed Apr. 21, 1958, Ser. No. 729,918 Claims. (Cl. 24259) This invention relates to a protective member for an edge of relatively thin flexible material and more particularly to an enclosing clip for such edge.

An object of this invention is to provide an enclosing protective clip member for an edge of a relatively thin flexible member which is easily made and easily assembled with the material and which makes a strong permanent connection with the material so that the clip may be gripped and pulled without disengaging from the flexible material.

Another object of the invention is to provide a unitary protective clip for enclosing the edge of a relatively thin sheet or web of flexible material comprising a hollow elongated body formed of material having slight spring properties, a pair of flanges at opposite edges of the body spaced apart from each other a distance at least equal to the thickness of said flexible material and said flanges being formed to interlock with each other with the flexible material captured therebetween upon assembly of the clip with the material and movement of the flanges toward and past each other to maintain a tight grip on the flexible material edge.

Further objects and advantages Will become apparent from the following detailed description taken in connection with the accompanying drawings in which:

FIG. 1 is a perspective elevational view of a sheet of flexible material having the clip aflixed thereto;

FIG. 2 is a fragmentary perspective view showing the clip in initial association with a sheet of flexible material;

FIG. 11 is a view similar to FIG. 9 showing the clip in fully assembled relation with the flexible material; and

FIG. 12 is a fragmentary plan view of the structure shown in FIG. 11 with parts broken away.

While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention and a modification thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.

As shown in FIG. 1, the protective clip 10 is attached to the lower side of a sheet 11 which may be hung from a wall by clips as indicated at 12 or may be withdrawable from a reel holder as commonly found or used in connection with maps and charts.

As shown more particularly in FIGS. 2-6 the protective clip 10 is formed by a rolling operation as a unitary construction of a metal, such as cold rolled steel, having a slight amount of spring temper. The clip 10 has spaced apart

side panels

15 and 16 which are connected by an intermediate panel '17 to form three sides of an enclosure. An outwardly turned flange 18 with an exposed raw edge 19 is associated with the side panel 15 by a rib 29 extending from a ridge 21 formed by a reversely curved section of the side panel 15. By this construction the outwardly turned flange 18 is located to overlie the intermediate panel 17.

The side panel 16 has an outwardly convex ridge 22 which supports an inwardly turned flange 23 formed by a reverse curve in the material. This flange 23 has a free edge 24. The ridge 22 is spaced from the intermediate panel 17 a greater distance than the flange 18.

The protective clip prior to assembly with the sheet of flexible material is as shown in FIG. 2 in which the

free edges

19 and 24 of the

flanges

18 and 23, respectively, are spaced from each other a distance at least equal to the thickness of the sheet material to enable assembly of the clip with the sheet material with the edge of the material within the enclosure formed by the clip. Also the flange free edges extend beyond each other along their length with the free edge 24 of the flange 23 spaced a lesser distance from the intermediate panel 17 than the free edge 19 of the flange 18.

With the parts in initially assembled relation as shown in FIG. 2 a lateral force may be applied to the side panel 16 as shown in FIG. 3 to cause the inwardly turned flange 23 to ride over the outwardly turned flange 18 and further movement of the

side panels

15 and 16 toward each other results in the inwardly turned flange 23 snapping over the outwardly turned flange 18 into interlocking relation therewith with the flexible material 11 captured therebetween.

The snap action of the flanges is facilitated by the springiness of the material and the free edge 19 of the outwardly turned flange 18 constitutes a raw edge to bite into the material 11 and more securely hold the material.

The protective clip has many uses such as with maps and charts and other materials, such as window shades, which are pulled down and provides a member which may be grasped to eflect the pulling. The clip also is usable to protect the otherwise exposed edge of a sheet material.

In the embodiment of FIGS. 7-12 the protective clip has a generally cylindrical shape rather than the rectangular shape of the embodiment of FIGS. 1-6. The protective clip is in the form of an elongated member 40 secured to the underside of a sheet of material 11 and the elongated member is inwardly concave to form a partially cylindrical shape and is formed of material such as cold rolled steel having a slight amount of spring temper.

An outwardly turned flange 41 is disposed within the periphery of the member and supported by a rib 42 joining a reversely curved ridge 43 along an edge of the member. An inwardly turned flange 44 is formed at the other edge of the member 40 and is spaced from the outwardly turned flange 41 a distance equal at least to the thickness of a sheet of material 11.

The inwardly turned flange 44 is located generally opposite a gap between a free edge 45 of the outwardly turned flange 41 and the ridge 43 with a free edge of the inwardly turned flange extending beyond the free edge 45 of the outwardly turned flange 41. The free edge 45 of the outwardly turned flange 41 is spaced from the ridge 43 a distance approximately equal to the thickness of the member 40 and twice the thickness of the sheet material whereby the sheet 11 may wrap around both sides of the inwardly turned flange 44 when the

flanges

41 and 44 are snapped over each other into overlapped interlocking relation.

The parts are shown in initially assembled relation in FIG. 9 and the application of laterally directed force to the parts results in an intermediate assembly position, shown in FIG. 10. In this position, the gap between outwardly turned flange 41 and ridge 43 has been increased by the flexibility of the connecting rib 42 and further lateral pressure positions the parts as shown in FIG. 11 in which the outwardly turned flange 41 has returned to an interlock position with the inwardly turned flange 44. In addition to this interlocking action a further squeeze is imparted to the paper to provide a tight gripping action by the spring action of the outwardly turned flange 41 pressing a part of the member 40 adjacent the inwardly turned flange 44 toward the ridge 43. It will be seen that in this embodiment a pull on the paper will tend to tightly maintain the locked overlap relation between the

flanges

41 and 44.

It will be seen from the foregoing description that a protective clip has been provided which protects the edge of the material from damage and securely holds the edge of a sheet or web of material so that the clip may be engaged for pulling the sheet of material from a holder.
