Abstract
A hasp for connection between an edge of a door and an adjacent member for holding the door in a locked position includes a first mounting plate having a top portion and a bottom portion with a pivot rod spanning the portions and carrying a link bar having an inner end mounted on the first mounting plate member for pivotal movement relative thereto between a lock position in which an outer end overlies a second mounting plate member and a release position in which the outer end is spaced from the second mounting plate member. A lock hanger is mounted on the second mounting plate member so as to extend in a direction substantially at right angles to the link bar when the link bar is in the lock position. The lock hanger is shaped such that an end portion thereof passes through an opening in the link bar when in the lock position. The lock hanger is adjustable in a direction to increase or decrease the length projecting through the link bar for receiving the padlock so as ensure that the padlock is tight to prevent prying. A cover portion over the lock prevents direct hammer blows on the lock and comprises an arched peripheral wall portion having two parallel side edges each attached to the link bar at longitudinally spaced positions therealong and a substantially flat top wall portion having a straight top edge extending longitudinally of the link bar between the side edges of the peripheral wall portion and attached to the link bar, the flat top wall portion being inclined from the top edge in a direction extending outwardly from and transversely to the link bar to a peripheral edge connected to the peripheral wall portion such that an impact from an impact tool in a direction transverse to the link bar tends to slip off the top wall portion away from the link bar.
Description
TAMPER RESISTANT HASP
This invention relates to a tamper resistant hasp for connecting a door to an adjacent member for locking the door in a closed position.
BACKGROUND OF THE INVENTION
Conventionally a hasp is arranged for connection between an edge of a door and an adjacent member for holding the door in a locked position, and comprises a first mounting plate member for attachment to one of the door and the member; second mounting plate member for attachment to the other of the door and the member; a link bar mounted on the first mounting plate member for movement between a lock position overlying the second mounting plate member and a release position spaced from the second mounting plate member; a lock hanger mounted on the second mounting plate member so as to extend in a direction substantially at right angles to the link bar when the link bar is in the lock position; the lock hanger being shaped such that an end portion thereof passes through an opening in the link bar when in the lock position, the end portion of the lock hanger having a hole for receiving a padlock.
In some cases the first mounting member can be mounted on the door and the second on an adjacent surface or vice versa. The adjacent surface can comprise a fixed post or another pivotal door.
This type of hasp is open to attempts to force the padlock from the door to gain forced entry either by applying vertical blows downwardly onto the padlock or by applying a lever under the padlock.
Attempts to reduce tampering are shown in US Patents 3,572,062 (Beebe) issued Mar 23~d 1971; 3,736,016 (Garvey) issued May 29th 1973;

DETAILED DESCRIPTION
A lock device 1 comprises a back reinforcement plate 3 which is fixed to a door by a plurality of support bolts 7 and fastened by nuts 9. The back reinforcement plate 3 is parallel to with the door 5. A spacer plate 11 of rectangular shape with the first sides 3A of the reinforcement plate 3 being longer than the second sides 3B of the reinforcement plate 3, is fastened to the door by two adjustment bolts 13 and two adjustment nuts 15. The adjustment bolts 13 are of equal distance from the first side 3A and equal distance from the second sides 3B.
Spacers 17 are placed between to spacer plate 11 and the door 5 on the adjustment bolts 13.
A lock holder 19 shaped so that it passes through an opening in the link bar 37 when in the lock position extending forwardly in a horizontal direction though the door 5. Spacers 17 are placed in their respective positions to ensure that the lock holder 19 is in the proper position.
Located at the furthermost end of the lock holder is a circular hole 21 in which the hook of a lock is inserted. To provide maximum security the spacers are added or taken out to keep the lock holder tight to the door, preventing instruments being wedged between the hasp 1 and the door 5.
Protecting the lock from being tampered with is a cover 23. The cover consists of a inclined cap 25 and a main cover portion 27. A pivotal flap 29 which is positioned flush with the door 5. The inclined cap 25 extends outwardly and downward from the furthermost top end of the pivotal flap 29 to the main cover portion 27 and is inclined to deflect hammer blows. Attached to the forward most end of the inclined cap 25 is the main cover portion 27 which forms a peripheral wall substantially surrounding the padlock. The cover 23 is shaped to form a circular tube which has an open end 31 for hand access to the hold portion 21 for attaching and protecting the lock.
A triangle support member 33 is attached to the inside wall of the inclined cap 25, to the pivotal flap 29 and to a disc member 35 to add extra support for the hasp 1.
The pivotal flap 29 and the cover 23 consist of a link arm 37 which is parallel to the door 5 when in the closed position and extends horizontally and is circular shaped at the end 41 to create a hinge 39. The circular end 41 surrounded a hinge bar 43 and is secured with a weld joint 45.
The hinge bar 43 is attached to two front plates 47A and 47B. The first front plate 47A is located above the hinge 39 and the second front plate 47B
is located below the hinge 39. The front plates are fixed to the second door 5A
by a back plate 47C. The back plate are large in size to spread any force exerted on the outside of the hasp 1 over a large area of the inside of the door 5A
preventing the looking system 1 from being pried or hammered off.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
a second mounting plate member for attachment to the other of the door and the member;
a link bar having an inner end mounted on the first mounting plate member for pivotal movement relative thereto between a lock position in which an outer end overlies the second mounting plate member and a release position in which the outer end is spaced from the second mounting plate member;
a lock hanger mounted on the second mounting plate member so as to extend in a direction substantially at right angles to the link bar when the link bar is in the lock position;
the lock hanger being shaped such that an end portion thereof passes through an opening in the link bar when in the lock position, the end portion of the lock hanger having a hole for receiving a padlock;
