Hasp with cylindrical lock

Abstract

Improvements in a hasp are disclosed. The hasp allows for locking the hasp with a cylindrical lock to operate on a door such as, but not limited to, a garage door, a roll-up door or a shed door. This configuration allows for upgrade or replacement of these types of door locks without requiring re-design or replacement of the door. The cylindrical locks offer a greater protection because they can't be “picked” using traditional lock picking tools. This makes the lock safer from people that may try to break into the door. The cylindrical lock fits primarily within the hasp. This prevents a person from grinding through the lock or shackle. The shackle can be configured with just the circular opening for the key visible. It can be further enclosed to prevent infestation from bugs such as hornets that can fill the inside of the hasp with dirt.

(8) FIG. 1 shows a prior art hasp 10. The hasp 10 is constructed with a rod 11 that is connected to a sliding tongue 16. In this figure the tongue 16A is located on the right side of the hasp 10 with the rod 11 protruding out the right side of the top 12 and the bottom 18 housings. The movement locking tabs 14A and 14B divide the top and bottom housings 12 and 18. To move the rod 11 from one side or the other, within the hasp 10, the slide tongue 16 is lifted and passed between the movement locking tabs 14A and 14B. The rod 11 also forms a hinge pin whereby the top and bottom housings 12 and 18 can pivot on the rod 11.

(9) When the top 12 and bottom 18 housings are closed the location of the sliding tongue is held within the right side as 16A or the left side as 16B. The shackle of a lock is placed through the holes 13A/B or 15A/B to hold the hasp 10 closed and prevent movement of the rod 11. The bottom of the hasp 10 has a plurality of square holes 17 for locating a carriage bolt within the hasp 10. In the prior art embodiment, the shackle of a lock maintains the hasp in position.

(10) FIG. 2 shows a hasp 20 for a cylindrical lock and FIG. 3 shows the open hasp 20 with a cylindrical lock. There are a number of structural differences between the embodiment that is shown and the prior art hasp to operate the hasp 20 for a cylindrical lock. This embodiment also (optionally) maintains the circular holes 23A/B and 25A/B to allow a user to use the hasp with a shackle style padlock. The major differences involve:

(11) A) The rounded rectangular holes 33A/B/C that allows the cylindrical lock to be located in the right side of the hasp 20 and rounded rectangular holes 33A/B/C for the cylindrical lock to be located on the left side of the hasp 20.

(12) B) The cylindrical lock retainer 24. The cylindrical lock retainer 24 has rounded rectangular holes 33C and 35C whereby the tab lock 53 is inserted into the hasp 20 to a depth whereby the tab lock 53 is rotated 55 within the respective interior space of the cylindrical lock retainer to maintain the cylindrical lock 50 within the hasp 20.

(13) C) The cylindrical lock retainer 24 has one or a plurality of slide lock tabs 29 that holds the slide tongue 26 in position 26A or 26B. While this embodiment shows two slide lock tabs 29, only one slide lock tab 29 is needed to maintain the slide tongue 26 in either position 26A/B.

(14) D) The slide tongue 26 has a vertical bend 44. The vertical bend maintains the majority of the surface of the slide tongue 26 against or in closer proximity to the bottom housing 28. This provides additional clearance for the cylindrical lock retainer 24 and the cylindrical lock. Due to the lower position of the slide tongue 26 within the hasp 20, the slide tongue 20 has a clearance hole or a fastener hole 27 that allows the head of a carriage bolt (or other fastener) that is inserted into holes 40, 41A, and 41B to protrude into or through the slide tongue 26. The holes 40, 41A and 41B are shown as square holes to prevent rotation of a carriage bolt, but could also be round.

(15) The slide tongue 26 is welded or otherwise secured to the rod 21 at the top portion of the vertical bend 44. When the top 22 housing of the hasp 20 is opened from the bottom 28 housing of the hasp (as shown in these figures) the slide tongue 26 can be easily positioned left or right of the interior of the housing. An additional advantage of this embodiment is that the housings do not require a complete opening to allow movement of the slide tongue 26 and further the slide tongue 26 does not need to be lifted to slide 60 the slide tongue 26 from 26A to 26B. These figures also show an optional vertical support 42 that can be used to increase the structural strength of the cylindrical lock retainer 24. Once the housings 22 and 28 are closed 61 the slide tongue 26 is maintained in position 26A or 26B where it is prevented from movement by slide lock tab 29.

(16) The cylindrical lock 50 has a lock face 51 where a cylindrical key fits into the lock to rotate 55 the tab lock 53. The cylindrical lock 50 has a larger rounded face with a wall or flat 56. The flat 56 engages in the outside of the rounded rectangular hole 33A or 35A depending upon the side where the cylindrical lock 50 is inserted. The flat or wall 56 prevents over insertion of the cylindrical lock 50 into the rounded rectangular holes. It also positions the tab lock 53 within the inside of the cylindrical lock retainer 24.

(17) The flat 52 fits onto the flat sides of the rounded rectangular holes 33A/B/C or 35A/B/C to prevent rotation of the cylindrical lock 50 when it is inserted into holes 33A/B/C or 35A/B/C. This allows a user to rotate 55 the tab lock 53 to lock or unlock the cylindrical lock 50 in the hasp 20. A fastener 54 retains the tab lock 53 on the end of the cylindrical lock 50. When the tab lock 53 is aligned with the flat 52 of the cylindrical lock 50 the cylindrical lock 50 can be easily inserted 62 and removed from the holes 33A/B/C or 35A/B/C of the hasp 20. When the cylindrical lock 50 is properly inserted into the hasp 20, the tab lock 53 is rotated 55 behind the rounded rectangular hole 33C or 35C the cylindrical lock 50 is prevented from removal from the hasp 20 and movement of the slide tongue 26 is prevented to lock the position of the rod 21.

(18) FIG. 4 shows a front view of the hasp with the cylindrical lock inserted and FIG. 5 shows a perspective view of the hasp with the cylindrical lock inserted. In FIG. 4 the slide tongue 26B is shown in the left side of the hasp where it is prevented from movement to the right by the slide lock tab 29. The top 22 and bottom 28 housings are essentially maintained in a parallel relationship when the cylindrical lock in inserted into the hasp. The vertical bend 44 of the slide tongue is shown connecting to the protruding end of rod 21B on the left, with a shorter portion of the rod 21A on the right side of the hasp. The tab lock 53 of the cylindrical lock is shown extending from the flat 52 of the cylindrical lock. This prevents removal of the cylindrical lock. The flat 52 is essentially sandwiched in the hasp between the tab lock 53 and the back of the lock face 51.

(19) The oblique view from FIG. 5 shows the lock and hasp configuration from FIG. 4 where only a portion of the rod 21B is shown extending out of hole 43B. The holes 23A/B and 25A/B are aligned to allow for insertion of one or more shackle lock(s). The shackle lock can be used with the cylindrical lock, instead of the cylindrical lock or in combination where both the shackle lock and cylindrical lock must be removed to open the hasp 20. It is also possible that two cylindrical locks and to shackle locks can be used with the hasp at the same time and thereby requiring all four locks to be removed to move the rod 21B. Typically, only one lock is inserted, and the side where the lock is inserted is based upon access or interference with walls or supports on the sides of the hasp where insertion of a key or removal of the lock is restricted on one side of the hasp but not on the other side of the hasp. One of the fastener holes 40 is shown in this figure, and the fastener would be inserted into the hasp with the head being located internal of the top 22 and bottom 28 housings.

(20) It is contemplated that the holes for the shackle can be removed and the top or bottom housing being configured with a cover 46 that protects the internal features of the hasp and prevents intrusion from insects, tools or tools that can harm the integrity of the hasp.

(21) Thus, specific embodiments of a hasp with cylindrical lock have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
