United States Patent Oflice 3,203,031 Patented Aug. 31, 1965 3,203,031 COMBINATION HINGE AND DETENT Ted L. Youngdale and Louis L. Youngdale, both of 818 Crescent Drive, Vista, Calif. Filed May 31, 1963, Ser. No. 284,545 2 Claims. (Cl. 16-145) The present invention relates to hinges generally and in particular to a combination hinge and detent structure useful in cabinet work for mounting doors on openings in cabinets and providing detent means for holding the doors in the closed position.
An object of the present invention is to provide in a hinge and detent structure, a device which may be manufactured inexpensively, one which has features which allow its use on various types of cabinet doors, and one which has long life characteristics.
Another object of the present invention is to provide a hinge and detent for cabinet doors which is sturdy in construction, one simple in structure, and one highly effective in action. I
These and other objects and advantages of the present invention wil be fully apparent from the following description when taken in connection with the annexed drawings, in which:
FIGURE 1 is a fragmentary view of a portion of a cabinet door and associated jamb, the door being shown partially in section and the jamb in section, with the hinge structure of the present invention installed thereon,
the door being shown in closed position,
FIGURE 2 is a view similar to FIGURE 1 showing the door in open position,
FIGURE 3 is an elevational view,
FIGURE 4 is a view similar to FIGURE 1 showing a modified form of the invention, the door being shown in closed position,
FIGURE 5 is a view of the assembly shown in FIGURE 4 with the door in open position,
FIGURE 6 is an elevational view of the structure shown in FIGURES 4 and 5.
FIGURE 7 is a view similar to FIGURES 2 and 5 of a second modified form of the invention, the door being shown open,
FIGURE 8 is a view of the assembly shown in FIGURE 7, the door being shown in closed position,
FIGURE 9 is an elevational View of the assembly shown in FIGURES 7 and 8,
FIGURE 10 is a view similar to FIGURES 1, 4, and 8, of a still further modified form of the invention, the dotted line showing indicating the swinging movement of the door to open position, and
FIGURE 11 is an elevational View of the structure shown in FIGURE 10.
Referring in detail to the drawings in which like numerals indicate like parts throughout the several views, and with particular reference to FIGURES 1 to 3, inclusive, the device of the present invention is indicated generally by the reference numeral 12 and it is shown installed upon a jamb 14 and door 16 of the type conventionally associated with cabinets.
The hinge structure or device 12 comprises a first plate member 18 and a second plate member 20 having their one adjacent ends hingedly connected together in the conventional manner as at 22 in FIGURES 1 and 2.
The first plate member 18 is L-shaped and has its short leg 24 overlying the exterior face of the jamb 14. The long leg 26 of the member 18 extends over the end of the jamb 14 and projects beyond the inner face of the jamb 14 as shown most clearly in FIGURE 1.
The second plate member 20 is Z-shaped with the first section 28, a second or intermediate section 30, and a third or free end section 32.
The first section 28 overlies the short leg 24 of the member 18 and the second or intermediate section 30 overlies the adjacent portion of the long leg 26 when the door 16 is in the closed position. The third section 32 projects perpendicularly with respect to the long leg 26 of the member 18 when the door is in the closed position as shown in FIGURE 1.
A free rotatable roller 34 carried on trunnions 36 projects from the section 32 of the second member 20.
A keeper, indicated generally by the numeral 38, is in the path of movement of the roller 34 when the door 16 executes its swinging movement toward and away from the jamb 14.
The keeper 38 comprises a member 40 pivotally connected to a bracket 42 which projects from the long leg 26 and biased in one direction by a spring.44 which bears against the long leg 26 of the plate member 18 and also bears against a shoulder 46 provided on one end of the member 40.
Wood screws, as at 50, are employed to secure the first and second plate members 18 and 20 to the jamb 14 and door 16, respectively,in the conventional manner.
With reference to FIGURES 4 to 6, inclusive, the plate member 20 is identical as previously described but the plate member 18' carries on its long leg 26' an S-shaped keeper 52 which is in the path of the movement of the roller 34 on the member 20 when the door 16 executes its movement toward and away from the jamb 14.
A portion of the keeper 52 adjacent one end, is secured to the long leg 26 by means of a bridge element 54 struck out from the long leg 26' and into which is threaded a set screw 56 bearing against the adjacent portion of the keeper 52 and locking the same in its position of adjusted movement relative to the roller 34.
With reference to FIGURES 7 to 9, inclusive, a further modified form of the invention is shown in which the plate member 20 has welded thereto a yoke 58 supporting the rotatable roller 60. The long leg 26" of the member 18" supports another keeper 62 by means of a slot element 64 struck out from the long leg 26". A set screw 66 threaded through the element 64 serves to secure the keeper 62 in any position of its adjusted movement in the path of movement of the roller 60 upon execution of swinging movement of the door 16 relative to the jamb 14.
With reference to FIGURES 10 and 11 a fourth and final form of the invention is illustrated in which a first plate member 68, secured to the jamb 14, has mounted on it a roller 70, a yoke 72 supporting the roller 70.
Another plate member 74, having one end hingedly connected to the plate member 68, is secured to the door 16' and has a portion bent outwardly from the door, as at 76 and provided on its free end with a curved recess forming portion 78.
The plate member 74 is also provided with a slot 80 (FIGURE 11), through which projects a hooked end portion 82 of a resilient bar element 84. The other end of the bar element 84 is formed to a recess 86 and between the recess 86 and the portion 78 of the plate member 74 is a spring 88 which biases the bar element 84 to the position in which it engages the roller 70.
The bar element 84 also carries an L-shaped stop member 90 which has one leg bearing against the inner face of the door 16' when the door is closed as in full lines in FIGURE 10.
When the door 16' has been moved to the dotted line open position, FIGURE 10, the stop element 90 is free from the inner face of the door 16'.
When the door is in the closed position the roller 70 bears against the adjacent portion of the bar element 84, as shown in full lines in FIGURE 10 and keeps the door 16 in the closed position. Upon opening movement of the door 16' the bar element 84 rolls under the roller 70 from the full line position to the dotted line position with the spring 88 urging the bar element 84 to the position in engagement with the roller 70.
In each of the forms of the invention described there is a keeper on one of the plate members and a roller carried by the other plate member, the roller and keeper being engageable and acting as a detent to keepthe door in closed position after it has been swung to closed posit-ion.
While only preferred embodiments of the invention have been shown and described, other embodiments are contemplated and numerous changes and modifications may be made in the invention without departing from the spirit thereof as set forth in the appended claims.
What is claimed is:
1. In a hinge and detent structure for a door and an adjacent jamb in a cabinet, a first plate member adapted for attachment to said door, a second plate member adapted for attachment to said jamb, hinge means co-nnect-ing adjacent ends of said first and second members together for swinging movement relative to each other, a freely rotatable roller mounted on one of said members, and a resilient keeper mounted on the other of said members in the path of relative movement of said roller with respect to said keeper upon execution of swinging movement of one member relative to the other, said roller engaging said keeper when said first and second members are at the limit of their swinging movement in one direction relative to each other, a curved recess forming portion appended on the resilient keeper, a resilient bar element extending from a slot'on the other of said members, said bar element extending from said slot and having a formed recess at its end, a leaf spring interposed between :said curved recess forming portion and said formed recess for biasing the bar element to a position for engaging said rotatable roller.
