United States Patent 3,178,762 HINGE STOP Harris M. Whiting, 1044 Harvard Ave, Claremont, Calif. Filed Dec. 2, 1963, Ser. No. 327,294 1 Claim. (Cl. 16-491) The instant invention is generally concerned with hinge stops, and is more particularly directed toward a hinge stop of the type mounted, in an adjustable manner, directly upon one of the sleeve or barrel portions through which the hinge pin is extended.
It is a primary object of the instant invention to provide a sleeve portion mounted hinge stop which incorporates several significant features productive of highly desirable results not obtainable in the more conventional type hinge stop.
In conjunction with the above object, it is an object of the instant invention to provide a hinge stop which is infinitely variable between a hinge opening of approximately 90 and a hinge opening of approximately 180.
Also in conjunction with the first-mentioned object, it is an intention of the instant invention to provide a hinge stop wherein a gradual stopping of the hinge, as well as the door upon which it is mounted, is effected so as to avoid any sudden jarring.
Further, it is an object of the instant invention to pro vide a hinge stop wherein an adjustable means is incorporated so as to vary the degree of frictional engagement of the movable hinge leaf relative to the fixed hinge leaf thus adjusting the aforementioned gradual slowing down of the door prior to its engagement with the abutment provided so as to limit the opening of the door.
Likewise, it is an object of the instant invention to provide a device which is simple in construction, highly durable, and easily adapted to most conventional hinges.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is an elevational view of an open hinge with the stop of the instant invention mounted thereon;
FIGURE 2 is an enlarged partial cross-sectional view taken substantially on a plane passing along line 22 in FIGURE 1 illustrating the mounting of the stop so as to enable an opening of the hinge to approximately 180;
FIGURE 3 is a cross-sectional view similar to FIGURE 2, however illustrating the stop mounted so as to limit the opening to approximately 90;
FIGURE 4 is a cross-sectional view similar to FIGURE 3 wherein the hinge is closed; and
FIGURE 5 is a perspective view of the stop member itself.
Referring now more specifically to the drawings, the reference numeral is used to generally designate the stop or stop member comprising the instant invention. This stop member 10 is to be adjustably mounted on one of the cylindrical sleeve or barrel portions 12 fixed along the inner edge 14, and in fact in most cases integral therewith, of a hinge leaf 16, these sleeve portions 12 being intermeshed, in the manner illustrated in FIGURE 1, for the reception of an elongated hinge pin 18 therethrough.
The stop member 10 is preferably of a length slightly less than the length of the sleeve portion 12 upon which it is to be mounted, and it is generally arcuate in cross section, the arcuity being greater than 180, and preferably on the order of 245 thereby requiring that the stop 10 he slid longitudinally on the sleeve portion 12 with lateral removal of the stop 10 being impossible.
The inner surface 20 of the stop member 10 conforms closely in shape to the outer surface of the sleeve portion 12, that is, this surface 20 is substantially cylindrical ex- 3,178,752 Patented Apr. 20, 1965 cept for a slight outward bend, indicated by reference numeral 22, so as to conform to the transistion point between the sleeve portion 12 and the leaf 16 when the stop is orientated so as to stop the hinge at approximately as illustrated in FIGURE 2.
The stop member 10 is divided into two portions, a relatively narrow front or approach portion 24 and a wider rear or mounting portion 26. The outer surface 28 of the approach portion 24, while also generally arcuate in shape, diverges from the inner surface 20 from the extreme forward end 30 to an outwardly projecting shoulder or abutment 32 located at approximately midpoint along the outer surface of the stop 10, the outer surface of the rear portion 34 continuing from the outer extremity of the abutment 32 parallel to the inner surface. It is through this enlarged rear portion 26 that the mounting screw 36 is threaded, this mounting screw 36 having a case hardened point 38 for biting engagement into the subjacent sleeve portion so as to fixedly position the stop 10.
As will be appreciated from a comparison of FIGURE 4 with FIGURE 3, because of the diverging outer surface 28 of the approach portion 24, as the movable hinge 16 is swung, the inner edge 14 gradually engages with this outer surface 28 with the friction generated between the outer surface 28 and the inner edge 14 resulting in a slowing of this opening movement so as to prevent an abrupt or hard stop as the hinge 16 engages against the shoulder or abutment 32 thus eliminating any tendency for the stop 10 to become jarred loose as well as eliminating those other undesirable features normally associated with a door being abruptly brought to a hard stop.
In regard to this frictional engagement of the inner edge 14 of the movable leaf 16, it will be noted that this diverging outer surface 28 can be spaced closer to or further away from the sleeve portion 12 through the use of the locking screw 36 inasmuch as a slight additional tightening of the screw 36 after the point 38 is engaged, will result in a raising or flexing of the stop outwardly away from the sleeve portion 12, this clearly being shown in FIGURES 2, 3 and 4. This ability to vary the degree of frictional engagement will, as will be appreciated, greatly extend the useful life of the stop member 10.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
