Abstract

A portable privacy lock is disclosed for use in securing a door that swings on hinges from an open position to a closed position in which the edge of the door opposite its hinged side is adjacent to a closure surface with a clearance gap therebetween. The lock includes a flexible webbing which has a first end and a second end, and which is provided with a plurality of holes between said first and second ends. The lock also includes a first securing plate that is attached to the first end of the webbing and a second securing plate that is attached to the webbing at an intermediate position between the first and second ends thereof. The second plate is also provided with a hole that is aligned with one of the holes in the webbing. The lock also includes a latch that is adapted to receive a drawstring and to releasably engage it from motion with respect thereto, and a drawstring, one end of which is attached to the first plate or to the first end of the webbing. The drawstring is threaded through the holes in the webbing and the second plate to engagement with the latch. The lock is utilized by inserting the first plate through the clearance gap between the door and its adjacent closure surface. The latch is disengaged from the drawstring so that the drawstring may be pulled to fold the webbing to move the second plate into position across the clearance gap and on the opposite side thereof from the first plate, so as to secure the door from motion with respect to the adjacent closure surface. The latch may then be engaged to hold the drawstring so as to maintain the plates in position with respect to each other.

Claims

1. A portable privacy lock for use in securing a door that swings on hinges from an open position to a closed position in which the edge of the door opposite its hinged side is adjacent to a closure surface with a clearance gap therebetween, which lock comprises:

(a) a flexible webbing having a first end and a second end, which webbing is provided with a plurality of holes between said first and second ends;

(b) a first securing plate that is attached to the first end of the webbing;

(c) a second securing plate that is attached to the webbing at an intermediate position between the first and second ends thereof, said second plate being provided with a hole that is aligned with one of the holes in the webbing;

(d) a latch that is adapted to receive a drawstring and to releasably engage it from motion with respect thereto;

(e) a drawstring, one end of which is attached to the first plate or to the first end of the webbing, said drawstring being threaded through the holes in the webbing and the second plate to engagement with the latch;

whereby the first plate may be inserted through the clearance gap between the door and its adjacent closure surface and the latch disengaged from the drawstring so that said drawstring may be pulled to fold the webbing so that the second plate is moved into position across the clearance gap and on the opposite side thereof from the first plate so as to secure the door from motion with respect to the adjacent closure surface, whereupon the latch may be engaged to hold the drawstring so as to maintain the plates in position with respect to each other.

2. The lock of claim 1, wherein the first securing plate is attached along a portion of its length near its center to the webbing.

3. The lock of claim 1, wherein one end of the drawstring is attached to the first securing plate adjacent to its point of attachment to the webbing.

4. The lock of claim 1, wherein one end of the drawstring is attached to the first end of the webbing adjacent to its point of attachment to the first securing plate.

5. The lock of claim 1, wherein the second securing plate is attached substantially along its entire length to the webbing.

6. The lock of claim 1, wherein the first and second securing plates are adhesively attached to the webbing.

7. The lock of claim 1, wherein the first securing plate has a non-skid surface on the side thereof to which the webbing is attached.

8. The lock of claim 1, wherein the second securing plate has a non-skid surface on the side opposite that which is attached to the webbing.

9. The lock of claim 1, wherein the latch is adapted to releasably engage the drawstring from motion with respect thereto by frictional engagement.

10. The lock of claim 1, wherein the latch is attached to the webbing at or near the second end thereof.

11. The lock of claim 10, wherein the webbing is provided with three holes for passage of the drawstring therethrough, comprising a first hole near the point of attachment of the first securing plate to the webbing, a second hole in alignment with the hole in the second securing plate and a third hole near the point of attachment of the latch to the webbing.

12. The lock of claim 1, wherein the drawstring has a first end and a second end, and the first end of the drawstring is attached to the first securing plate adjacent to its point of attachment to the webbing, and a pouch that is adapted to contain the lock is attached to the second end of the drawstring.

13. A portable privacy lock for use in securing a door that swings on hinges from an open position to a closed position in which the edge of the door opposite its hinged side is adjacent to a closure surface with a clearance gap therebetween, which lock comprises:

(a) a flexible webbing having a first end and a second end, which webbing is provided with at least three holes between said first and second ends;

(b) a first securing plate that is attached along a portion of its length to the first end of the webbing;

(c) a second securing plate that is attached substantially along its entire length to the webbing at an intermediate position between the first and second ends thereof, said second plate being provided with a hole that is aligned with one of the holes in the webbing;

(d) a latch that is attached to the webbing near the second end thereof, said latch being adapted to receive a drawstring and to releasably engage it from motion with respect thereto;

(e) a drawstring, one end of which is attached to the first securing plate or to the first end of the webbing, said drawstring being threaded through;

(i) a first hole in the webbing near the point of attachment of the first securing plate to the webbing;

(ii) a second hole in the webbing that is in alignment with the hole in the second securing plate; and

(iii) a third hole in the webbing near the point of attachment of the latch to the webbing;

to the latch for engagement therewith;

whereby the first plate may be inserted through the clearance gap between the door and its adjacent closure surface and the latch disengaged from the drawstring so that said drawstring may be pulled to fold the webbing so that the second plate is moved into position across the clearance gap and on the opposite side thereof from the first plate so as to secure the door from motion with respect to the adjacent closure surface, whereupon the latch may be engaged to hold the drawstring so as to maintain the plates in position with respect to each other.

14. The lock of claim 13, wherein one end of the drawstring is attached to the first end of the webbing by being sewn thereto.

15. The lock of claim 13, wherein the first end of the webbing is attached to the first securing plate near a central portion thereof.

16. The lock of claim 13, wherein the first and second securing plates are adhesively attached to the webbing.

17. The lock of claim 13, wherein the first securing plate has a non-skid surface on the side thereof to which the webbing is attached.

18. The lock of claim 13, wherein the second securing plate has a non-skid surface on the side opposite that which is attached to the webbing.

19. The lock of claim 13, wherein the latch is adapted to releasably engage the drawstring from motion with respect thereto by frictional engagement.

20. The lock of claim 13, wherein the drawstring has a first end and a second end, and the first end of the drawstring is attached to the first end of the webbing adjacent to its point of attachment to the first securing plate, and a pouch that is adapted to contain the lock is attached to the second end of the drawstring.
