DOOR STOP AND HOLDER This invention relates to hardware, and more particularly relates to door stops and holders.

The present invention provides a new and improved door holder and stop of simplified and economical construction which may be mounted to a door and wall having varying degrees of reveal therebetween and which permits a wide latitude in the relative mounting as between the door mounted portion and the wall or floor mounted portion.

Door stops and holders of the general type to which this invention pertains generally comprise a holder member and a keeper member mounted in cooperating relation on a door and an adjacent wall or floor. The holder member may be provided with a spring-biased roller or ball which is adapted to be received in a groove in a keeper member. The cooperating action is such that as the keeper strikes the spring-loaded roller it moves it upwardly and the loading on the roller then forces it downwardly into the groove defined in the keeper to provide a latch or holding action therebetween.

The prior art discloses many such arrangements. However, in such arrangements the relative placement of the holder and the keeper is very critical inasmuch as the keeper must be placed in such a position that the groove defined therein is always aligned with the axis of the roller. This problem has partially been overcome by forming the keeper as a rotatable turret-like member so its angular position may be adjusted. However, this requires an additional part, increases the expense of the device, and the degree of possible alignment is still within a narrow angular range.

In the present invention the slot or groove in the keeper is defined along an arcuate path or on a radius, and the roller is formed with a mating contour along its length. With this arrangement the relative placement of the keeper and holder members is not critical and the assembly may be utilized with doors having varying amounts of reveal over a wide range.

An object of this invention is to provide a new and improved door stop and holder assembly.

Another object of this invention is to provide a new and improved door stop assembly which provides a greater latitude in relative placement of the keeper and holder members with varying reveal of the door.

The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of this specification.

However, the invention both as to organization and operation, together with further objects and advantages thereof may best be appreciated by reference to the following detailed description taken in conjunction with the drawings, in which:

FIG. 1 is a view of a door and wall (partly cutaway) seen from above;

FIG. 2 is a view seen in the plane of lines 2-2 of FIG. 1;

FIG. 3 is a plan view of a keeper member of the assembly of FIG. 2;

FIG. 4 is a view seen in the plane of lines 4-4 of FIG. 2;

FIG. 5 is a view of the holder assembly of FIG. 2 seen from the rear thereof;

FIG. 6 is a view of the wall mounting plate and bumper in the assembly of FIG. 2;

FIG. 7 is a view seen in the plane of lines 7-7 of FIG. 5; and

FIG. 8 is a floor-mounted keeper which may be utilized in the invention.

As shown in FIG. 1, an assembly embodying the invention comprises a keeper or striking 'member 11 and a holder member 12. As exemplified, holder member 12 is mounted to the back of a door 13 which is hinged at 14 to a wall 15 defining a door opening. Door 13 together with a sidewall 16 defines a reveal R. The wall-mounted striking member or keeper 11 is mounted to wall 16 as by means of screws 17 extending through a back plate portion 18 that has an outwardly extending portion 19 terminating in an arcuate striking surface 20. Defined in keeper 11 adjacent the striking surface thereof is an arcuate slot 21 adapted to receive a detent roller as hereinafter described.

Mounted to door 13 as by means of screws 22 is a mounting plate 23 having outstanding ears 24 which are tapered outwardly from top tobottom as more clearly shown in FIG. 6. Carried on plate 23 adjacent the lower portion thereof is a resilient bumper 25 which may be rubber or other suitable resilient and sound-deadening material.

The holder member 12 comprises a housing member 27 having a back wall 28 with the inner side edges 29 thereof tapered outwardly from top to bottom complementary to the taper on ears 24 of back plate 23. As more clearly shown in FIG. 4, housing member 27 is further defined with surfaces 30 adapted to mate with the rear surfaces of ears 24 on back plate 23.

With this construction housing 27 is positively and firmly attached to the door 13 by sliding the rear surface thereof over ears 24 to firmly seat housing 27 and then setting set screw 31 against the back surface of one of cars 24.

A pin or shaft 32 is set in housing 27 as by being received in slots 33 defined in opposite interior side walls of housing 27 and a portion 34 of the housing is then peened under pin 32 to securely mount it to housing 27. Pivotally mounted to pin 32 is a carrier member 36 which is acted upon by a spring 37 at the other end thereof. Intermediate the action point of spring 37 and pin 32 is a shaft or pin 38 carried between spaced apart, depending walls 39 and 40 of carrier 36. Rotatable on pin 38 is a barrel shaped roller 41 adapted to be received in slot 21 as shown in broken line in FIG. 3.

An adjusting screw 42 extends through an opening 43 in the top wall of housing 27 and the head thereof rests on a relieved shoulder. The shank of screw 42 receives a nut 44 thereon having. a slot 45 defined in the periphery thereof to receive an end 46 of spring 37. The upper surface of nut 44 is spaced from boss 48 on housing 27 by a washer 49. The opposite end of spring 37 is formed with a portion 50 (FIG. 4) which abuts upstanding tab 51 on carrier member 36. This construction of the ends of spring 37 prevents rotation thereof upon adjustment of screw 42 and further prevents rotation of nut 44 when screw 42 is adjusted. Nut 44 will then move linearly on screw 42 to adjust the tension in spring 37. Washer 49 prevents the tensioned spring from forcing screw 42 upwardly.

The washer 49 which is received in an annular slot defined in screw 42 acts against the under surface of boss 48 to prevent any outward movement of screw 42. The walls 39 and 40 of carrier member 36 may be formed with edges 53 which will abut the inside front surface of housing 27 and limit rotational movement of carrier member 36 under the bias of spring 37.

In operation, when the door 13 is opened a sufficient distance, housing 27 will be moved back over the end surface 20 of keeper or striker 19. Depending upon the force at which the door is opened the end surface 20 may abut pad 25 and cushion the impact. As the door 13 rebounds, roller 41 under the biasing of spring 37 acting on carrier 36 will enter slot 21 and hold the door in a latch or door holding position.

It will be apparent from the construction of the pivot point (pin 32) of carrier'member 36 in relation to the location of roller 41 and the spring seat that a greater force is required to unlatch the door than is required to latch it.

When striker 19 initially engages roller 41 at the time the door is being opened, the normal from the axis of the roller to the tangent at the point of engagement will be substantially perpendicular to the line joining the axis of the roller and the axis of pin 32 about which carrier 36 rotates. Thus substantially all of the striking force acts perpendicular to the lever arm defined between the axes of

pins

32 and 38.

The disengaging force applied to roller 41 by surface S which partially defines slot 21 will be essentially parallel to a line or plane passing the axis of pin 32 and the axis of roller 41 and only a small component of the force exerted on roller 41 by surface S will be effective to rotate carrier 36 in a counterclockwise direction as viewed in FIG. 2.

The total force required for engagement and disengagement will be a factor of the geometry of the dimensions of the carrier and the axis of pin 32 and roller 41 taken together with the constant of spring 37 and the adjustment of screw 42. Therefore, with this arrangement the mechanism may be made to latch with a minimum of force while a much greater force is required for unlatching.

FIG. 8 exemplifies an alternate striker member 54 adapted to be floor mounted. A base portion 55 has screw or bolt mounting holes 56 defined therein and an upstanding portion 57 with an arcuate slot 58 defined in the upper surface 59 thereof adapted to receive roller 41 therein.

The

arcuate slots

21 and 58 in the striking members, together with the roller 41 with its barrel shape, permit the use of this assembly on doors having varying degrees of reveal. This arrangement makes the relative placement of the striking member and the holding member less critical. Engagement and latching of the two members may be effected even though as much as half of the length of the roller may extend beyond the

slots

21 or 58.

It may thus be seen that the objects of the invention set forth as well as those made apparent from the foregoing description are efficiently attained. While preferred embodiments of the invention have been set forth for purposes of disclosure, modification to the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art.
