ATTORNEY "United States Patent ()ffice 3,562,849 Patented Feb. 16, 1971 3,562,849 HINGED HANDLE ASSEMBLY Donald C. Brayshaw, 206 Eustis St., Roxbury, Mass. 02119 Filed May 1, 1969, Ser. No. 820,977 Int. Cl. A47b 95/02; Eb 1/100 US. Cl. 16126 9 Claims ABSTRACT OF THE DISCLOSURE A hinged handle assembly is disclosed in which the ends of a hand grip are connected by pivots to uprights on supports attached to a wall of an object. Each upright has a chamber through which the connecting pivot extends and to which the inner end of a coil spring is connected. The other end of the spring is attached to the upright and the springs urge the grip into an inoperative position relative to the wall. The upright has a. shoulder and the end portions of the grip and the shoulders having portions engageable to limit the extent to which the grip may be swung both with and against the spring action.
The present invention relates to hinged handle assemblies.
The advantages of having a hinged handle yieldably biased into an inoperative position have been recognized but have not been freely realized, particularly when strength, long life, and compact grip supports are requirements.
The principal objective of the invention is to provide hand grip assemblies that will meet the above generally stated requirements, an objective attained by providing supports attached to a wall of an object and having an upright and a shoulder at its bottom projecting from one end face. End portions of the hand grip carry fixed pivots rotatably supported by the upright and at least one of the uprights has a chamber opening through its other face through which the pivot extends that is supported by that upright. A coil spring within the chamber anchored to the pivot and to that upright, yieldably urges the hand grip into an inoperative position relative to the wall and the end portions of the hand grip and the shouders have surfaces that are mutually engageable to limit the extent to which the hand grip may be swung both with and against the action of the springs.
In the accompanying drawings, there is shown an embodiment of the invention illustrative of these and other of its objectives, novel features, and advantages.
In the drawings:
FIG. 1 is a perspective view of a handle assembly in accordance with the invention,
FIG. 2 is an exploded view and on an increased scale, of the connection between one end portion of the grip and one of the supports,
FIG. 3 is a view of one of the end supports with the closure of its chamber removed to show the spring with the grip inoperatively positioned thereby,
FIG. 4 is a like view but with the grip positioned for use,
FIG. 5 is a view showing the relationship between an end portion of the grip and the shoulder of the support With the grip inoperatively positioned,
FIG. 6 is a like view showing that relationship when the grip is positioned for use, and
FIG. 7 is a section taken approximately along the lines 77 of FIG. 1.
In the drawings, a fragment of a wall of a case, drawer, or other object is indicated at .10 to which supports for a hand grip are secured, the supports being generally indicated at 11 and the grip being generally indicated at 12 and shown as U-shaped.
Each support .11 is shown as having an attaching stud 13 depending from its flat bottom surface 14 and extending through the wall 10 and anchored by a transverse pin 15 hearing against a washer 16 interposed between it and the wall 10. Each support includes an upright 17 having a circular chamber 18 opening through One end face and a bottom shoulder 19 extending in the opposite direction. The shoulder 19 and the end face of the upright .17 proximate thereto are plane surfaces and disposed at right angles to each other. It is preferred that the supports 11 be disposed with their chambers 18 opening toward each other.
The end portions 20 of the grip 12 are parallel and spaced apart to receive the supports 11 between them. The end portions 20 carry fixed pivots 21, each rotatably supported by the proximate upright 17 and extending axially through its chamber 18. The free end of each pivot 21 has an end slot 22 to slidably receive and hold the inner end 23 of a coil spring 24 whose outer end terminates in a hook 25 caught on a pin 26 fixed within the chamber 18. The spring is tensioned when installed to yieldably hold the grip 12 in its inoperative position in which, see FIGS. 1 and 5 the edge 27 of each end portion 20 rests against the appropriate shoulder 19. As may best be seen in FIGS. 3 and 4, each pin 26 is located in vertical alignment with the axis of the pivots 21 and the pivots have their slots 22 in alignment therewith when the grip 12 is inoperatively positioned to ensure that, in the assembled handles, the springs function uniformly.
Washers 28 and 29 are supported by each pivot 21, one washer 28 between each end portion 20 and the proximate face of the support 11 to which it is connected and one washer 29 between each spring 24 and the end wall of its chamber 18. Each pivot 21 has an annular groove adjacent its free end to hold a keeper 3.1 against the recessed margin 32 of the chamber 18 by which a cover disc 33 is detachably held.
As may best be seen in FIGS. 5 and 6, the edge 27 of each grip end portion 20 has a rounded junction 34 with the extremity 35 thereof enabling the grip 12 to be swung into an operative position approximately at right angles to the support 10 before the extremity 35 butts against the shoulder 19.
It will thus be apparent that hinged handle assemblies meet a wide range of requirements ensuring satisfactory service with the convenience of a handle yieldably and securely held in an inoperative position.
1. A hinged handle assembly comprising a pair of end supports for attachment to a wall of an object, each support including an upright and a shoulder projecting laterally from the bottom thereof, the proximate end face of the upright and the shoulder being plane surfaces and disposed at right angles to each other, a grip including end portions having parallel faces spaced and disposed so that each may lie close to the appropriate one of said first named end faces, a pivot fast on each end portion of the grip rotatably supported by the proximate upright, at least one upright having a chamber opening through a face opposite the shoulder into which the pivot supported by that upright extends, a coil spring in said chamber fastened at its outer end to a chamber wall and at its inner end to said pivot and urging the hand grip into an inoperative position relative to the wall, at least one end portion of the hand grip and the proximate shoulder including surfaces engageable to limit the extent to which the hand grip may be swung in at least one direction.
3 2. The hinged handle assembly of claim 1 in which both uprights have a chamber, a coil spring is in each chamber with its outer end fastened to a chamber wall and its inner end fastened to the pivot extending therein. 3. The hinged handle assembly of claim 1 in which at least one end portion of the hand grip and the proximate shoulder include surfaces engageable to limit the extent to which the hand grip may be swung in the other direction.
4. The hinged handle assembly of claim 1 in which each end portion of the hand grip and the shoulder of the upright to which it is attached includes surfaces engageable to limit the extent to which the hand grip may be swung in either direction.
5. The assembly of claim 2 in which the chambers open towards each other.
6. The assembly of claim 1 in which the pivot extends through the chamber of the support to which it is attached, a cover has a hole through which the pivot also extends and which is engageable with the upright to close the chamber, and a fastener on the free end of each pivot holds the cores in its chamber closing position.
7. The assembly of claim 6 in which the face of the upright through which the chamber opens has a recess marginally of the chamber in support of the margins of the cover.
8. The assembly of claim 4 in which the extremity of each end portion of the grip is engageable with the shoulder of the support to which it is connected when the grip is operatively positioned and an edge portion engageable with that shoulder when the grip is inoperatively positioned and the junction between that edge and the extremity is rounded thereby to enable the grip to swing from one position to the other.
9. The assembly of claim 1 in which the width of each shoulder is substantially equal to the thickness of the upright above the shoulder and of the end portion of the grip connected thereto.
