Application February 11, 1939, Serial No. 255,845
This invention relates to a door stop and more particularly to a hinge stop attachment therefor, although certain features thereof may be employed with equal advantage for other purposes.
It contemplates more especially the provision of a simple, inexpensive and improved hinge stop attachment that can be utilized in conjunction with standard building door hinges serving as mounts for doors that open both parallel as well as angularly to a wall. Numerous types of door stops have heretofore been proposed in conjunction with hinge mounts therefor, but these are expensive and require spe cial hinge constructions that preclude their use with doors of standard construction now available and commonly used in building structures. Then, too, the hinge stops of known construction are not adaptable for use on present door constructions which are in use and cannot be advantageously changed to provide an adjustable stop therefor of known construction. It is often that doors cannot be permitted to swing to limit their open position adjacent a wall because there may be numerous obstructions such as the requirement to place furniture in the path thereof.
As a result, injury is occasioned to the door as well as the furniture unless a positive stop is provided. This usually takes the form of a floor mounted stop which is undesirable for numerous well known reasons such as impairment to the floor as well as the obstruction occasioned thereby when the door is not in its extreme open position. Floor mounted stops as well as the'customary door stops on the base-board of the wall are not entirely advantageous or desirable in that they serve as obstructions causing damage to the person as well as appliances such as vacuum cleaners, buggies and other movable objects that are often displaced in the path thereof All of these shortcomings render it undesirable to utilize the cus tomary base-board and floor mounted door stops as well as the specially constructed hinges that have been provided for an equivalent purpose, the latter being too expensive as a substitute for standard hinges and for that reason have not been adopted to any extent.
One object of the present invention is to simplify the construction and improve the operation of devices of the character mentioned.
Another object is to provide a durable, inexpensive and effective hinge stop attachment that is operable in a variety of positions.
Still another object is to provide a resilient door catch and complemental stop hinge attachments capable of radial engagement and disengagement for use with standard door hinges.
A further object is to provide a door step having a plurality of obstructions for cooperation with a door catch to constitute hinge attachments to arrest the opening of a door in a variety of positions without shock.
A still further object is to provide a resilient door catch as a cooperable element with a door stop having a series of obstructions to define limiting positions in conjunction with standard hinge plates.
Still a further object is to provide door stop attachments capable of application to standard building door hinges to predetermine the positions of the door without resort to the usual baseboard or floor mounted stops.
An additional object is to provide a plate mounted to the pintle of a hinge for cooperation with a resilient catch adjustably anchored to a door to limit the door opening movement to a variety of predetermined positions or a selected position.
Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

Figure 9 is a perspective view of a limit trip attachment for the door stop shown in Figure 5.
The structure selected for illustration comprises a substantially circular door stop plate or disc I9 that is cast, stamped or otherwise shaped from The door catch plate I9 is provided preferablywith an axial aperture I8 sized to fit the diameter of a standard hinge pintle shank I9 that terminates at its upper end in a peripheral flange 29 constituting a part of an ornamental head 2 I, in this instance and for the most part of substantially spherical shape in accordance with standard hinge pintle construction. Commonly the pintle shank I9 is provided with diametrically opposed nibs 22 and 23 in the region of the peripheral flange 28 for cooperation with a similarly shaped bore provided in the upper loop 24 of a standard hinge plate 25 that is screwed or otherwise attached to the door opening in the countersunk door opening surface 26 in the door frame I1.
Accordingly, the axial aperture IS in the hinge attaching plate I 8 is shaped correspondingly with diametrically opposed grooves 21 and 28 to receive the correspondingly disposed, shaped, and sized pintle nibs 22-23 for registry therewith to hold the door catch plate In against relative movement with the pintle I9. Th pintle nibs 22-23 are usually of sufficient length to be received for the entire extent of a top hinge loop 24 in the standard hinge plate 25 so that the comparatively narrower door catch plate I9 will still permit the pintle nibs 23 to engage with the diametrically opposed grooves 21-28 therein as well as afford the usual registry with a portion of the door loop 24 of the door hinge plate 25. Consequently, the door catch and hinge attaching plate I8 will be held against movement by the pintle I9 as well as by its arm I I anchored to the exterior surface of the door frame I1 by the fastener I8 projecting through the aperture I in the flange I2. As a result, even though the standard hinge should not be possessed with a provision for the pintle nibs 22-23 and such should not be found on any particular door mounting hinges in use, the door catch plate arm II together with its anchoring flange I2 will serve to retain the door stop III against relative rotation with a door 29.
As shown, the door 29 has its hinge plate 30 mounted in a countersunk end portion 3| provided therein as an expedient of common practice. Wood screws or other suitable fasteners 32 secure the moveable hinge plate 39 to the door 29 in the customary manner. It is tobe noted that the movable hinge plate 39 terminates in spaced loops 33 in registry with correspondingly shaped and sized loops 24, 24', and 24" constituting a part of the fixed hinge plate 25 so that the pintl 19 will extend therethrough to serve as a pivotal mount for the door 29. This constitutes a standard hinge mount for doors 29 to maintain same relative to a fixed door frame I1 constituting apart of the adjacent wall of a building structure.
Consequently, the door stop hinge attaching plates II] can be mounted beneath the pintle flange 29 against rotary movement with the door 29, hinge plate 30 and its integral pintle receiving loops 33. Additional rotary movement of the stop plate I9 is precluded by its arm II mounted by means of the screw fasteners I6 projecting through the apertures I5 in the flange I2 for anchored engagement in the exterior surface of the wood door frame I1. It is to be noted that the door stop plate I 9 is, in this instance, provided with a circular periphery 34 having a series or plurality of transverse notches or grooves 35, 36, 31, 38 and 39, in this instance five, provided therein.
The transverse peripheral grooves 35, 36, 31, 38 and 39 provide an interrupted path for a door catch plate 49 preferably though not essentially stamped from spring steel to provide a resilient oifset curved arm 4| that gradually converges to a fraction of its width at its extreme edge 42. The extreme edge 42 extends in the general direction and substantially parallel to the body of the plate 49 which is of substantially rectangular configuration. It is to be noted that the edge 42 is reversely bent to provide a reinforced groove engaging catch 43 that is resiliently disposed in the path of the periphery 34 of the door stop plate I8 and particularly to become lodged by the progressive intermittent movement from one groove to another depending upon the application of increased force in opening or closing the door 29 relative to its stationary frame I1.
In order to mount the door catch plate 40 in operative relation with the door stop I8, the body of the plate 48 is provided with longitudinally elongated slots 44 and 45, in this instance two, that are stamped or otherwise provided therein along the longitudinal median line thereof to receive fasteners therethrough such as wood screws 46 and 41, respectively. Consequently, the door catch 49 can be adjusted within the limit of the slots 44-45 relative to the door catch plate I8 to provide the desired frictional cooperation of the reinforced edge 43 of the door catch with the grooves 35, 36, 31, 38 and 39.
To preclude any accidental displacement of the door catch plate 40 relative to the door stop plate I9, the elongated fastener mounting slots 44-45 are provided with a series of arcuate interruptions 48 and 49 to present intermediate nibs 50 and 5!, respectively, that obstruct the free movement of the plate 40 relative to the screw fasteners 43-41 even though the latter should become loose. Consequently, the resilient and engaging edge 43 of the door catch plate 49 can be maintained in any adjusted relation with the cooperating peripheral edge 34 and its plurality of notches 35 to 39 to eifect the desired engagement and intermittent pause of the door 29 in any angular adjusted position relative to its fram I 1, thereby limiting the movement as conditions may require in any particular building structure or room thereof.
In the closed position of the door 29, the door catch edge 43 will be lodged in the first notch 35 on the plate I0 and will retain the door against making movement even though the customary door lock is inoperative for that purpose. Then, too, the door 29 will be held against accidental opening in response to draught or other unusual air movement in a building structure. In the next position, the engaging edge 43 of the door catch 49 will become lodged in the next notch 36 and sequentially the notches 31, 38 and 39 depending upon the extent to which the opening of the door 29 should be limited.
When the engaging edge 43 of the door catch 49 is lodged in the last notch 39 proximate to the door stop arm II, the door 29 is in its extreme open position substantially parallel to the wall which extends from the external surface of the door frame l1, thereby holding the door in its extreme open position without permitting the door to engage or strike the wall and precluding the accidental closing thereof in response to any draught or unusual air movement. In this position, the door 29 will be retained open until purposely displaced by an attendant who will have to apply sufficient forc to effect the displacement of the door catch edge 43 from the various grooves 35 to 39 provided on the periphery 34 of the door stop I'll.
In order to have the door stop l9 together with its catch 43 serve to limit the open extent of displacement of the door 29 without contacting any of the grooves 35 to 39 and especially the intermediate grooves 36 to 38 inclusive, an auxiliary trip consisting, in this instance, of confronting plates 52-53 that are maintained in spaced parallel relation for a distance equivalent to the thickness of the door stop H) which is freely received therebetween. This is effected by means of a spacing rivet 54 that projects through the smaller ends of the plates 5253 and maintains them in rigid spaced relation and together with the plates 5253 serves as a stop for the door catch engaging extremity 43 that will be disposed in the path thereof as will appear more fully hereinafter.
To enable the confronting plates 52-53 to be held in any selected radial position on the door stop It, the plates 52-53 are provided with aligned apertures 55 that have diametrically opposed grooves 5351 to correspond with the door stop axial aperture l8 and its diametrical grooves 21-28 for alignment therewith with the pintle I9 projecting therethrough so that the rivet 54 will be lodged in any of the grooves 36, 31 or 38. It will be noted that the radial distance between the axis of the trip rivet 54 and its aligned apertures 55, corresponds with the distance between the axis of the door stop aperture l8 and the parallel groove 35 to 39, thereby maintaining the trip 52-53 in any radial position so that the rivet 54 will serve as a stop or trip for the door catch extremity 43.
The door catch 43 with its engaging edge 42 is, in this instance, removed sufficiently from the periphery 34 of the door stop III to preclude engagement with the grooves 35 to 39 thereon and yet be disposed in the path of the trip rivet 54 to contact therewith after the door 29 has been swung toits maximum open limit determined by the position of attachment of the trip 52--53 thereon. It will be apparent, therefore, that a variety of functions can be acquired with the use of a comparatively simple structure serving as a hinge attachment and an adjustable stop for doors 29 relative to their mounting frames H.
To render the door catch 49 inoperative relative to the stop plate II], it will only be necessary to loosen the screws 46-41 and displace the plate 40 from the door stop III for a sufiicient distance to avoid inter-engagement therebetween. This construction of parts having the features described herein provides an effective and combined door stop and limit means. A very inexpensive, suitable, and effective hinge attachment is thus provided that is capable of use in conjunction with any standard hinge.
Various changes may be made in the embodiment of the invention herein specifically described without departing from the invention or sacrificing any of the advantages or features thereof, and nothing herein shall be construed as limitations on the invention, its concept or structural embodiment as to the whole or any part thereof except as defined in the appended claims.
