Description
United. States Patent 2,989,859 NARROW STILE DOUBLE BOLT DOOR LOCK Charles L. Earls, North Hollywood, Calif., assignor to Adams Rite Manufacturing Company, Glendale, Calif., a corporation of California Filed Aug. 29, 1958, Ser. No. 758,130 Claims. (Cl. 70-116) The present invention relates generally to lock mechanisms of the type utilized for doors having a narrow stile; and is more particularly concerned with improvements in such lock mechanisms as make use of a bolt pivoted for swinging movement to extended and retracted positions.
Although the present invention is described and claimed in connection with lock mechanisms finding particularly advantageous use with narrow stile doors, the invention is likewise applicable to other doors, where space is not a limitation. It is therefore contemplated that the invention shall not be limited solely to use on narrow stile doors.
It is one object of the present invention to provide a locking mechanism with pivoted bolt, which is especially adapted for use in connection with doors having a narrow stile, wherein a key control cam actuator is arranged to be rotated completely through 360 from a key insertion and removal point.
A further object is to provide a locking mechanism with pivoted bolt, wherein it Will be impossible to remove the key in any but completely locked or unlocked positions of the bolt, thus eliminating any possibility of the bolt being inadvertently left in an unlocked position rather than in a desired locked position.
A further object is to provide in a lock mechanism a 360 key cylinder actuator which operates on a bolt actuating lever, rather than directly on the bolt.
Another object is to provide actuating mean for a lock mechanism, the actuating means including a cam extension which is retained connected with a bolt actuating lever and released for continued movement to a key insertion and removal position only when the bolt has been fully actuated to a locked or unlocked position.
In addition to the above mentioned objects, the present invention embodies a plurality of bolts which may be actuated from a single operating control mechanism. Heretofore, manually operable bolts have been utilized at either the top or bottom, or both, of doors in addition to theusual locking means which are generally installed between the top and bottom of the doors adjacent a vertical edge of the door. Such construction, particularly in the case of public buildings, constituted a hazard and potential danger at times of confiagration. The bolts being manually operable and at an abnormal height, required stooping or bending in order to-operate them. Sometimes under stress of conflagration and excitement such abnormal position constituted a dangerous operation. Realizing this, fire laws have been passed which require that the locking and bolting combination must be effected by single operation. The present invention admirably meets these requirements and contemplates a combination lock and bolt arrangement which may be operated simultaneously from a normal door height Without the necessity of stooping or bending.
A still further object is to provide a lock mechanism in which the bolt means includes a plurality of simultaneously operable bolts under control of a single actuating means.
It is also an object to provide in a lock mechanism a plurality of simultaneously operable bolt structures, one of which is supported for rotational movement, While the other is supported for reciprocable movement.
' Yet another object is to provide a lock having a plurality of bolts, one of the bolts being placed intermediate the top and bottom of the door, While the other is arranged to bolt the same door at the floor level, thus acting to hold the door from rocking and vibration.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
Referring to the accompanying drawings, which are for illustrative purposes only:
FIG. 1 is a perspective view of a lock mechanism embodying the features of the present invention, together with an associated door jamb;
FIG. 2 is an enlarged fragmentary sectional view, taken substantially on line 2-2 of FIG. 1, showing the cooperative relationship of the lock components, the bolt being in extended position;
FIG. 3 is a view similar to FIG. 2, except that the bolt is shown in retracted position; and
FIG. 4 is an enlarged fragmentary rear view.
Referring more specifically to the drawings, for illustrative purposes, there is disclosed in FIG. 1 a lock casing which is designated generally by the numeral 10. This casing comprises generally a pair of side plates 11 and 12 which are secured in spaced apart relation by conventional spacing pins or other means, and including a face plate 13 which may be removably attached as by suitable screws 1414 at the forward edges of the side plates. This face plate is formed with a rectangular slot or opening 15 within which a bolt structure 16 is movable to retracted and extended positions, as will hereinafter be explained more fully.
The bolt structure 16, in its locked or extended position, is adapted to extend into a suitable opening 17 formed in an edge face 18 of an associated jamb or another door 19. The bolt 16 is shown as a laminated structure in which a plurality of metallic plates 20a-20b, 21a21b and 22 are secured together by suitable rivets 23 or other conventional means. The bolt is pivotally mounted for swinging movements through an angle of substantially between its extended and retracted positions, a pivot pin 24 being positioned between the bolt ends, this pin having its opposite ends supported in the side plates 11 and 12 respectively.
The configurations of the inner ends of the bolt plate members are perhaps best shown in FIGS. 2 and 3. The innermost end of plate 22 is terminated short of the pivot pin 24 in an angularly extending end edge 25 beyond which extends the adjacent ends of the other plates, thus forming a space 26 therebetween. The adjacent ends of the outermost plates 20a and 20b are similarly formed and comprise a sector portion which is bounded by an arcuate edge 27 which terminates at its ends in abutment shoulders '28 and 29. These shoulders are spaced substantially 90 apart and are adapted to engage a stop pin 30 to limit the movement of the bolt 16 between its retracted and extended positions. The inner ends of the plates 21a and 21b are likewise similarly formed and have a sector portion having an arcuate edge 31 in registration with the arcuate edge 27. The arcuate edge 31, however, extends from the abutment shoulder 29 past the shoulder 28 and terminates in an outwardly extending shoulder 32.
The adjacent ends of the two outermost plates on each side :thus have overlapping end portions which receive the pivot pin 24 therethrough and support the bolt for pivotal rotation. The sector portions of the plates 20a and 21a on one side of the bolt, and the corresponding portions of the plates 20b and 21b on the other side of the bolt are provided with a radially extending slot 33, and in substantially 90 relation'to this slot are provided with a Y-slot 34 having dwell positions at its ends as indicated by the numerals 35, 36 and 37 for a purpose which will hereinafter be explained in detail.
The bolt 16 is actuated between its retracted and extended positions by means of an actuating lever 38 supported for swinging movement on a pivot 39 at one end, this pivot being vertically positioned with respect to the pivot pin 24 of the bolt 16. The other end of the actuating lever extends into the space 26 of the bolt and carries a transversely extending pin 40 having its ends respec tively positioned on opposite sides of the lever and respectively positioned in the adjacent Y-slots 34 of the bolt structure. As thus arranged, the lever 38 is constrained to limited swinging movement between the forward and rear edges of the side plates 11 and 12.
Provision is made for positively releasably locking the bolt 16 in its retracted position and its extended position. This is accomplished by detent means associated with the lever 38, which includes a cylindrical detent 41 which is best shown in FIG. 4. The detent is provided with a circumferentially extending groove '42 intermediate its ends which forms a portion 43 of reduced diameter, this portion being slidable in a slot 44 in the actuating lever. As shown in FIGS. 2 and 3 this slot is constructed with an enlarged end portion 45 to facilitate mounting the detent in its operative position. The outermost ends of the detent 41 are respectively positioned for movement in arcuate slots 46 respectively formed in the side plates 11 and 12. The slot 46 has dwell notches 47 and 48 at its ends. The detent is biased in an upward direction in the slot 44 by a coiled spring 49 placed on each side of the actuating lever 38, one end of the coil spring being secured to an anchor pin 50 carried by the lever, and the other end of the spring bearing against and seated in a circumferential groove 51 formed in the detent. As thus arranged, the detent will be biased into the dwell notch 47 in the extended position of the bolt 16, and into the dwell notch 48 in the retracted position of the bolt, as respectively shown in FIGS. 2 and 3. In the dwell positions of the detent 41, the detent assumes a position between transversely extending spaced abutment pins 52 and 53, as shown in FIGS. 2 and 3 respectively.
' Various mechanisms may be utilized for motivating swinging movement of the lever 38, and with the lock structure disclosed herein, provision is made for actuat ing the lever from either side of the lock casing. For purposes of illustration, a lock cylinder 54 of conventional type operable by a key is mounted in an opening 55, such an opening being formed in each of the side plates 11 and 12 for the accommodation of the lock cylinder. The lock cylinder carries rotatably mounted means 56 having a cam extension 57. The rotatably mounted means 56 is controlled by a key by means of which the cam extension may be rotated through 360 in opposite directions from a key insertion and removal position. It will also be observed that the center of rotation of the rotatably mounted means 56 is vertically aligned with the center of rotation of the actuating arm pivot 39, but offset relatively thereto.
Advantage is taken of the path of movement of the cam extension 57 with respect to the movement of the abutment pins 52 and 53, which enables the utilization of the cam extension to serve the dual purpose of releasing the detent 41 and thereafter shift the actuating arm from one of its locked positions to the other so as to motivate the bolt 16 from one position to the other. As shown in FIG. 2, the detent is positioned in the dwell notch 47 and the pin 40 is positioned in the dwell position 35 of the Y-slot of the bolt. In this position, the bolt 16 is positively locked in its extended position. Should it be desired to move the bolt to its retracted position, the cam extension 57 would be rotated in a counterclockwise direction from the key insertion and removal position, which in this case is when the extension is extended vertically upward. Upon movement of the cam extension to the position shown in FIG. 2, it will be observed that the abutment pins 52 and 53 are in such a position that the outermost end of the cam extension will pass the abutment pin 52 and move into engagement with the detent 41. Continued movement of the cam extension will cause it to force the detent from the dwell notch 47 and to a position which permits the extension end to pass between the abutment pins 52 and 53. As the cam extension comes in contact with the abutment pin 53, the applied forces will now shift the actuating arm 33 to the position shown in FIG. 3. In this position, the bolt 16 will be in a retracted position, and the pin 40 will be in the dwell position 36 of the Y-slot. In this position of the arm, the detent 41 will be biased into the dwell notch 48, as the cam extension is continued in its counterclockwise movement. In this position of the actuating arm, it will be observed that the abutment pin 53 has assumed a position which will permit the end of the cam extension to pass by this abutment pin and be continued in its movement to the key insertion and removal position. The action of the lock elements will be similar to that just described except in reverse order, when rotating the cam extension from the key insertion and removal position in a clockwise direction. During actuation of the bolt between its retracted and extended positions, the pin 40 will move into dwell position 37 of the Y-slot at an intermediate position of the bolt. Moreover the curvature of the Y-slot is such that the pin 40 will act to restrain free movement of the bolt in going from an extended position to retracted position.
From the foregoing description, it is believed that it will be evident that the key cannot be removed and inserted at a position which would leave the bolt in other than a fully extended locking position or a fully retracted unlocked position.
As a further feature of the present invention, the bolt means is disclosed as including a reciprocably mounted floor bolt structure as generally indicated by the numeral 59, this bolt being arranged for simultaneous actuation with the bolt 16 by operation of common actuating means previously described.
More specifically, the floor bolt comprises an upper plate member 60 and a lower rod member 61, these two members being interconnected by conventional means 62 so that their overall length may be increased or decreased to meet variations in installation conditions. In the present instance the means 62 is shown as Comprising a nut 63 which is rotatably supported in a bracket 64 on the lowermost end portion of the upper plate member 60. The lower rod member has an upper end portion 65 which is threaded for operative association with the nut 63. The lowermost end of the rod member 61 projects through an opening 66 in the bottom face of the door structure, this end thus being arranged to be reciprocably moved to an extended position or retracted position simultaneously with the movement of a bolt 16 to its extended and retracted positions.
As shown, the plate member 60 is of elongate construction and extends transversely between side plates 11 and 12 which retain the plate member against edgewise movement. The plate is shown as having engagement with a roller 67 which extends between and is supported by the side walls 11 and 12. As shown, the plate member is provided with an elongate clearance slot 68 through which extends a supporting screw 69 for the casing 10.
At its uppermost end, the plate member 60 is reduced in width to form a head end 70 which will fit between the inner surfaces of the bolt plates 20a and 20b. The head end carries a central projection 71 which is adapted to extend into the space 26, this projection carrying a transversely extending pin 72, the ends of this pin being respectively positioned in the radially extending slots 33 of the bolt 16, and adjacent vertically extending slots 73 formed in each of the side walls 11 and 12. With this arrangement, the rotary motion of the bolt 16 is utilized to move the pin 72 reciprocably in the slot 73 and thus motivate floor bolt structure 59 to its extended and retracted positions simultaneously with the movement of the bolt 16 to its corresponding positions. Moreover, the locking mechanism associated with the actuating arm 38 is also utilized to lock the fioor bolt in its respective positions.
From the foregoing description, it is believed that it will be appreciated that the lock structure described accomplishes the stipulated objects set out for the invention.
Various modifications may suggest themselves to those skilled in the art without departing from the spirit of my invention, and, hence, I do not wish to be restricted to the specific form shown or uses mentioned, except to the extent indicated in the appended claims.
