<p>1,037,791. Sliding clasp fasteners; releasable fastenings. G. F. D. VANDAMME Feb. 24, 1964 [May 3, 1963], No. 7535/64. Headings E2A and E2S. A safety device for locking at least one sliding clasp fastener on articles such as camping tents comprises a first element 5 with a recess 9 for holding the sliders 2a of the fastener or fasteners 1, 2, 3, devices 11 for holding this first element on the material of the tent, a second element 6 forming a lid co-operating with the first element to form a box adapted to enclose the sliders therein, devices for connecting the two elements of the said box and devices intended to lock the said connection devices to prevent illicit opening. The safety device may be used for locking camping tents with three sliding clasp fasteners, the recessed element 5 having a screw-threaded rod and a clip 11 for holding the tent material in position. The element 6 has a hole 13 for traversal by the rod 10 and notches 14 for receiving the fasteners. When the tent material has been positioned between the two elements 5, 6 a winged nut 7 with holes 17 is screwed tight down on to the end of the rod 10 and a padlock 8 is passed through one of the holes 17 and a hole 16 in a projection on the element 6. In another embodiment (Fig. 6 not shown) the upper and lower elements 20, 19 are of circular cross-section and the device for holding the tent material comprises a projection 24 and a loop of wire 25 coiled around a pin 27 mounted on a yoke 28 of the element 19. The other extremity of the wire to the loop bears against the bottom of the box 19 and allows the tent material to be gripped between the projection 24 and the loop 25. The shaft is in the form of a rod 30 hingedly mounted on the pin 27 and held substantially at right angles to the box base by the wire 26. The rod 30 also has a notch 33 or a hole 37 which is engaged by a bolt 34 of a locking device secured to the upper box element 20. The hole 37 may also be used for the insertion of a padlock.</p> |
