4 Claiins. (Cl. 1 6-437) This invention generally relates to doorstops and more specifically to an. improveddoor stop particularly suitable for use with a door hinge of the type includinga pivot pin or pintle.
One of the objects ofthe present invention is to provide an improved-door stop which will efiectively check a door in various preselected open positions, regardless of the particular surface contour ofthe adjacent doorway frame with which it cooperates, while at the same time. effectively distributing its lead to such frame as well as to the door so as to minimize, the possibility ofdamage to theia'tter members. i
A further object of the present invention is to provide an improved door stop incorporating novel stop elements that are self-adjustable so as to permit the stop to be employed, with equal advantage, with-hinges and doors of various widths and at doorway frames, havingvvarious surface contours. i 1 Other objects willbein part obvious and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafterset forth and the scope of-the application which will be indicated-in the appended claims.
in the drawingsi 1 FIG. I is a fragmentary plan view, with portions shown in cross section, of a door and doorway frame in which a door stop constructed in accordance with the present invention, is shown aslbeing mounted ona hinge and in operable relationship withadoorand a doorway frame;
FIG. 2 is an enlarged cross-sectional view taken generally along lines 2.2 of FIG. '1;
FIG. 3 is, a perspective view of a shoe element included onthe door stop; and. I
FIG. 4 is a viewgenerally similar to FIG. 1 but showing the door stopntil-ized.withadifferent hinge and door construction.
Referring to the drawings in detail FIG. 1 shows a door stop generally designated 2, embodying the present invention, and positioned in operable relationshipwith a door 4, of the hollow-core type, and a doorway frame 6 including a molding piece 8,.the door 4 shown in open position as limited by the door stop 2. I
The door stop 2 includes a. frame ilti'formed of a suitable metal, and comprising a generally elongated leg portion 12 and a lateral projection or arm 14 extending from the leg portion '12, at about the mid-point between the two ends 16 and 13 thereof. At the end 16 of the leg portion 12 there is provided a mounting aperture or eye 2d adapted to receive a hinge pin or pintle 22 of an associated hinge 23 (as shown in FIG. 1)- to thereby mount the door stop 2 for pivotal movement At the other end 15 of the leg portion 12 there is provided a pair of arcuately extending guide flanges 24 projecting generally'normal to the end 13 of the leg portion 12 from the opposite sides thereof as best shown in FIG. 2
In accordance with one aspect of -the present invention, an adjustable shoe generally designated 3i for contacting the door 4, is slidably mounted for rocking move ment on the guide flanges 24 of the "frame leg portion 12-. 1 In the shown embodiment, the shoe 3%} is formed from a suitable resilient hard wearing, self-lubricating material, such as polyethylene plastic, and includes on ice one side, a fiat generally rectangular face 3-2adapted to engage the panel 5 of the door 4 (as shown in FIG. 1') and being formed of a suficient size so that the reaction force imparted to the door 4 by the stop willbe distributed overa relatively large area of the door panel to thereby avoid stress concentration thereon. This feature is, particularly important when the door stop is used in connection with a door of the hollow-core type illustrated, wherein the core-enclosing panels 5' are formed from relatively thin stock.
The: shoe 3%, as shown, further includes an arcuate. or curved face 34, on the side opposite that of flat, face 32, as best shown in PEG. 3. The curved face Sdofthe shoe is adapted to slidably engage the end surfacefid ofthe leg portion 12 which is curved to conform to the shoe face 34 and which forms the upper side, (as viewed'in the drawings) of the guide flange 24 of thestop frame it).
In order to slidably mount the shoe dil for rocking movement, on the guide flanges 2d of the frame 1%, the shoe is provided with a pair of arcuate ribs oriianges 4d projecting normaily from, thecurvedface 34 thereof.
and being spaced so as to engage the guide flanges 240i the frame idas shown in FIG. 2; Thearcuate ribs 46f of the shoe 30 are provided with inwardly extending tabs 42 spaced from the curved face li iand dimensionedto engage the lower surface (as viewed in FEG; 2) of'the. guide flanges so as to retain the shoe 39bit. the, guide flanges 2 5 but to Sit thereon.
. From the above it will be seen that upon engagement with the door 4, the shoe 3%? is free to rock. along the guide flanges Zaof the frame to thereby adjust to en: gage the surface Set the door 4 ina flat and even manner. In order to limit the sliding movement of the shoe 30 on the guide flanges Zd'so as to prevent accidental dislodgment o'f the shoe 3% from thestop frame 10; a ,pairof stop projections are provided on each ofthe ends of the guide fiangesld so as tobe engageable with the tabs 12 of the shoe dd to therebylimit the sliding movement of the shoe Fail. Installation of the shoe. 30 on the guide flanges is simply accomplished by inserting the stop projections 44 of, the guide flanges 24 under theta-bs 42 of the shoe St); N i
The arm 14 of the stopframe isprovided at the outer end thereof with a transversely extending boss tijhaving athreaded passage 52 extending therethrough and adapted to receive a correspondingly threaded stud or bolt.54 which extends generally parallel to the leg portion 12 so as to engage the molding 8 as shown in FIG; 1. V The bumper 7d is formed with a cavity 72 which receives the knob 56 of the bolt 54m removably retain the bumper 79 on the bolt 54, but to permit the bumper to undergo universal movement relative thereto so as to adjust to the contour of the surface 9 of the molding 8. The cavity 72 of the'bumper 79 is enlarged so as to have a greater dimension than the knob 56 and is provided with an enlarged entry port or throat 74 thereby permitting the bumper to self-adjust in all directions to conform to the molding surface 9 with the bumper disposed generally perpendicular thereto, regardless of lthe particular angular disposition of the bolt 54 relative to the surface 9 of the molding '8. a j
In use, the door stop'2 is pivotally mounted on the permit slidable movement of theshoej hinge pin 22 so that opening movement of the door 4 will be limited by engagement between the slidable shoe 30 and the door 4 and between the adjustable bumper 70 and the molding 8 as shown in FIG. 1. The particular position at which the door will be checked by the stop 2 may be selectively varied, as desired, by changing the longitudinal position of the bolt 54 through means of the threads thereon.
The adaptability of the stop 2 as provided by the adjustability of the shoe 30 and bumper '70 is clearly illustrated in FIG. 4 wherein the stop 2 is utilized on a hinge whose leaves 80 are of a lesser width than those of the hinge 23 described above and wherein the molding 84 has a somewhat different surface contour 86 than the molding 8 described above. In FIG. 4, the bolt 54 of the stop 2 is shown as having been longitudinally adjusted so that the stop will check the door in substantially the same position as shown in FIG. 1, while the shoe 30 and the bumper 70 are shown as having self-adjusted to meet the changed conditions of hinge width and molding contour.
It will thus be seen that when the stop 2 is in operative position such as shown in FIGS. 1 and 4, the door will not only be positively checked but also the shoe 30 and bumper 70 will automatically adjust to distribute the reaction force to the door 4 and the adjacent molding over an area sufliciently large so as to avoid excessive wear or damage on these members.
From the foregoing it will be seen that the present invention provides an improved stop that is extremely adaptable in use While at the same time being economical to manufacture.
As will be apparent to persons skilled in the art, various modifications and adaptations of the structure above described will become readily apparent without departure from the spirit and scope of the invention, the scope of which is defined in the appended claims.
