Application June 25, 1948, SerialNo. 35,260

2 Claims.

inventionrelates to closures for receptacles of flexible material, such as leather, fabric, etc.,

and it is an improvement over my Patent $72 ,255,598, of September .9, 1941, filed September 7, 1939.

The improvement has reference to the type of closure providing a rigid frame member forming one side of the aperture and serving as an abutment for a movable-framemember, formed of telescoping sections-with means for maintaining the movable frame member firm in either open or closed position by the inherent resilient resistance to. deformation of one of the telescopingime'mbfers; the movable frame member forming'the 'other"sid'e of the aperture when moved away from the rigid member.

An object of the invention is to provide a closure that will facilitate access into the receptacle through the aperture thereofv when open.

Another object of the invention is to provide a closure which will bring the upper edge of the movable frame member to lie in a plane different from that of the upper face of the rigid frame member when the aperture of the closure is open.

In the appended drawing forming part of this application:

Figure 1 is a fragmentary plan View of an end of a closure embodying one form of my invention.

Figure 2 is a section on line 2-2, Figure 1, showing the position of the telescoping members in reverse order from that shown in Figure 1.

Figure 3 is a plan view of a different form of my closure, and

Figure 4 is a section on line 4-4, Figure 3, showing the position of the telescoping members in reverse order from that shown in Figure 3.

In the description and. claims, the term rigid member includes either solid or tubular forms and of a triangular or trapezoidal cross section; the sloping side or face, whether one or two, of the rigid member that forms part of the contour of the aperture of the closure is symmetrically disposed with reference to the median longitudinal plane of the rigid member.

Referring to the drawing:

5 is a rigid member extending through the length of the aperture for which the closure is intended and, as shown in Figures 1 and 2, is of triangular cross section, the side 6 thereof forming the upper face of the closure while the opposite ridge 1 forms the bottom.

The lateral sides 8 of the rigid member 5 are (Cl.f15010i) 2 sloping inwardly with reference to a container that it is toacconrnnodate.

Pivotally mountedon eachsloping side S 'near the ends of the rigid'frame member 5 are hinges 9, the pivotal axes of said hinges 9 on the same sloping side are in 'a common plane parallel to the side 8 and i'n"which-plane the axes of the hinges are parallel to each other. The two hinges on the sameside areconnected to a mov'-' able frame membe -"comprising a spring section II), which is mounte'dflto telescope-in end sections H, each of which'h'a's one end connected to the adjacent hinge: The inherent resiliency of the spring section f0-tends to retain the shape itassumes whensheathed insections H or when extending out of said-sections- H;

As seen in Figure 2, one of the movable frame members is shown abutting the adjacent sloping side 8, while the other movable frame member is shown in an exaggerated open position, that is to say, moved away from the adjacent sloping side 8, and. when in the open position, the upper edge of the movable frame member will lie in a plane substantially perpendicular to the slope of the side to which it is attached. In consequence, a major part of the upper edge of the movable frame member will lie below the level of the top of the rigid member 5, with the central part thereof the lowest and the extremities thereof substantially at the level of the top, though in a different plane from that of the top.

Due to this relative position of the rigid and movable frame members, the aperture formed between them eases the accessibility into the receptacle through the closure.

In cases where the receptacle is large, a partition l2 may be provided through the length of the rigid frame member as indicated in Figure 2.

In Figures 3 and 4, the rigid member 5' is shown also triangular in cross section, except that the side 6 forms the bottom of the closure while the ridge I is at the top. The sloping sides 8', therefore, at the opening will slope outward, so that when a movable frame member, formed by telescoping sections I0 and II, is moved from the abutting position, as shown on the right side of Figure 4 to that shown on the left side thereof, it will bring the major portion of the upper edge of the movable frame member above the ridge 1' of the rigid frame member, thus fa-' cilitating the access to the receptacle through the closure.

The tendency of the spring section III or ID in the movable frame member is to offer resistance to deformation, due to the inherent resilient resistance to deformation when it is pulled to open or due to the frictional resistance of the various elements when it is pushed to close the opening between the rigid and movable frame members.

By forming a sloping side as part of the aperture of the closure from which the telescoping sections of the moving frame member swing out, so that the major upper portion of the edge is either above or below the upper face of the rigid frame member, as shown in Figures 1 and 2 or as shown in Figures 3 and 4 respectively. In either case the telescoping members form an acute angle with the longitudinal median plane of the frame 5 or 5' extending from the base 6 or 6' of the frame member between the sloping sides 8 or 8 of said frame member.. construction I obtained a better accessibility By this 2. A closure for receptacles comprising a rigid frame member of triangular cross section, one side of which is perpendicular to the median plane of the triangular member, each of the other two sides of which forming part of the aperture of the closure, and said two sides being symmetrical to said median plane and sloping with reference thereto, anda movable frame member on each sloping side and pivotally connected thereto at the ends of the rigid frame member, said movable frame members being formed of telescoping sections arranged to maintain said movable frame member firmly in either abutting position or when moved away from the rigid frame member, each of said movable members when being moved from the sloping side to which it is connected lies in a plane substantially perpendicular to the sloping side but at an acute through the aperture to the container provided with such a closure as described. .lclaim:

1. A closure for receptacles comprising a rigid frame member having a sloping side forming a part of the apertures'vcontoun a movable frame member formed of telescoping section s comple-, menting the apertures contour, and hinges at the ends of the rigid and movable framemembers, connecting the two, whereby said movable framemembercan be moved to and from the rigid frame member-in aplane'substantially perpendicular. to the. sloping side of the rigid memher but angular to the median plane ofthe rigid frame member,- said movable frame having a springvsection the inherent resiliency of which tends to retain the shape it assumes at the open or closed position of'the closure.
