(Cl. 1li-82) 2 Claims. 1
pair of exibly connected vacuum cups, one of which is to be caused to cling to an interior wall or other surface andthe other of such cups similarly to some portion of the inner face of the door.
My objects have been: economy of manufacture, durability, facility of attachment or detachment, universality of use, compactness for packaging, convenience of adjustability, avoidance of deformation of surfaces to which attached as also insurance against abrasive marring of any surfaces during use and the guarantee of silence vin operation without any frictional resistance. All the specied objects have been attained and commercial approval likewise through the use of cord-connected, rubber vacuum cups having perforated bosses through which the cords adjustably extend together with enlarged cord ends for preventing a separating withdrawal of the cord.
Adverting to the drawing:
Figure 1 is a perspective view of a refrigerator, with its door open and delimited in its opening movement by the appliance embodying my invention.
Figure 2 is a top plan view of the assembled appliance on an enlarged scale approximately its v actual size, as initially made and used.
Figure 3 is a still further enlarged, cross-sectional view through one of the rubber vacuumcups and cup-connecting cord.
Each of two concave-convex cups l carries on its convex side a protuberance or solid, rubber boss 2 of oval shape and provided with a, longitudinally extending hole 3 therethrough. Passed through the hole 3 of each cup is a flexible cord l of suitable length when its two extremities are knotted at 5 whereby to prevent their withdrawal and separation from the cups and after determination of the maximum distance between the two cups which it shall have been concluded to establish to permit the cord to become taut when the closure is in its desirably full-open position, depending upon the interior wall area of a refrigerator '6 and the inner surface of a door 'l to which the cups are to be firmly yet detachably aiiixed, as shown in Figure 1, so as selectively to control the range of door-opening swing.
1. The combination for use as a delimiter of the relative movement of a hinged closure with respect to itsV support, comprising a pair of vacuum-cups of predetermined interior contour and of adequate size and selectively attachable to said support and closure respectively and a flexible cord having its ends slidably connectedwith said cups and said cord being provided with means whereby the length thereof may be manually adjusted to provide various lengths between said cups and secured to each, said double adjustment permitting the cord to become taut and to serve as a check when said closure is in its suitably maximum open position, whereby a series of limited, open positions are achieved upon adjustment of said adjustable cording, the arrangement furthermore permitting the flexible cord to curl into available space behind the closure.
2. The combination as in claim 1, wherein a central area of the convex side of each cup is formed with a boss having a hole therein and the ends of the cord are detachably secured in the holes of said bosses respectively with the cordprovided means comprising the coniiguration of the end sections of the cord.
