Application April 23, 1954, Serial No. 425,157

1 Claim. (til. 292-285) This invention relates to an adjustable door hasp which is expansible longitudinally in order to be readily adapted for engagement with a staple thereby compensating for shrinkage or swelling of a door from rain, change in the weather or the drying out of green lumber used in the construction of the door.

An object of this invention is to provide an adjustable door hasp which is simple in construction, easy to utilize, positive in operation, well adapted for its intended purposes and relatively inexpensive to manufacture.

Another object of this invention is to provide an adjustable door hasp having a pair of longitudinally adjusted members positioned in overlying relation with one of the members including inturned side edges for guiding the sliding movement of the other said members.

A still further object of this invention is to provide an adjustable door hasp having means for limiting the sliding movement of one of the members in both directions thereby assuring that the device will be retained in assembled relation.

These, together. with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the adjustable door hasp of the present invention showing the device in assembled position for securing a door in closed relation to a door frame;

Figure 2 is a top plan section taken substantially along a plane through the longitudinal center line of the construction of Figure 1 showing the various details of construction thereof; and

Figure 3 is an exploded group perspective showing the various elements of the adjustable door hasp of the present invention.

Referring now specifically to the drawings, it will be seen that the numeral generally designates the adjustable door hasp of the present invention. The door hasp 10 includes a first elongated strap member 12 having a hinge barrel 14 at one end thereof for alignment with a pair of hinge barrels 16 positioned on one end of an attaching strap 18 which is provided with a plurality of apertures 29 for securing the strap 18 to a pivotal door closure 22. A hinge pin 24 is inserted through the hinge barrels i4 and 16 and provided with enlarged end portions for securing the hinge pin 24 Within the hinge barrels l4 and 16 thereby pivotally securing the elongated strap 12 to the member 18. As shown, the attaching strap as is positioned under the strap member 12 thereby concealing the fastening members which secure the plate it; to the door 22. The elongated strap 12 is provided with inturned edges 26 which are provided with abutting faces 23 along a portion of their length and with recessed portions along the outer portions of their length. The abutting edges 28 form 2,790,664 Patented Apr. 30, 1957 ice a hollow polygonal tubular member for slidably receiving a second elongated plate 32. The recess portions 30 adjacent each end of the inturned edges 26 form inwardly extending slots at each end of the inturned edges 26. The elongated plate member 32 is provided with an upturned projection 34 on one end thereof for sliding engagement with the slot formed by the recesses 3%) adjacent the hinge barrel 14. The end of the plate member 32 remote from the projection 34 is provided with an elongated closed end slot 36 for positioning over a keeper staple 38 secured to a suitable plate 40 attached to a door frame 42. Adjacent one end of the closed slot 36 nearest to the projection 34 is pivotally secured a locking lever 44 positioned on a projecting locking pin 46 which is slidably received in the slot formed by the recess portions 30 at the outer or remote end of the plate 12. The outer end of the locking lever 44 is provided with a T-sh-aped portion 48 having a pointed lower end for positioning in the staple 38 between the plate 32 and the outer end of the staple 38 when the slot 36 is positioned over the staple 38 in an obvious manner.

The operation of the device will be readily understood. The staple plate 40 is secured to the door frame 42 with the staple 38 projecting therefrom with suitable fastening members projecting through the apertures St) in the plate 20 in an obvious manner. The plate 18 is secured to the door closure 22 by suitable fastening members in an obvious manner and in alignment with the staple 33 so that the slot 36 will be positioned thereover when the door 22 is closed and the

plate members

12 and 32 swung about the hinge pin 24 thereby bringing the staple 38 in registry with the slot 36 and the locking lever 44 may be pivoted about the pivot pin 46 into engagement with the staple 38 thereby securely locking the door 22 in position. It will be seen that the inwardly extending slots formed by the recessed areas 30 will permit sliding movement of the plate 32 in relation to the plate 12 wherein the projection 34 limits the motion of the plate 32 in one direction and the pivot pin 46 limits the movement of the plate 32 in the other direction thereby capturing the plate 32 within the inturned edges 26 of the plate 12. It will be understood that this particular device will eliminate the necessity for constantly moving the staple 38 and the staple mounting plate 40 due to the shrinkage of the door 20 which may be caused by the construction of a door or frame from uncured or unseasoned lumber and also due to weather or humidity conditions. It will be understood that the device is of relatively simple construction thereby enhancing the economic feasibility of the device.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

An adjustable door hasp comprising a pair of overlapping elongated first and second members, the first member having a terminal hinge attachable to a door and being formed with a longitudinally extending polygonal tubular guide portion through which the second member slidably extends for movement in opposite directions to lengthen or shorten said hasp, said second member being provided with a lateral stop lug on one end, a slot in its other end for receiving a staple attached to a door frame, and a pivot pin thereon between said slot and lug pivotally supporting a hook engageable with a staple on a door frame, said tubular guide portion having longitudinal slots in opposite ends thereof opening at one end through the ends of the tubular guide and closed at the other end and in which said lug and pivot pin are movable into engagement with the inner 5 ends of the slots to limit movement of said second memher in opposite directions.
