<p>729,900. Key holders. BUXTON, Inc. Dec. 4, 1953 [Dec. 18, 1952], No. 33757/53. Class 44. A key hanger support for a key case is made from blanks 1, 13, Figs. 3 and 4, in which the slotted edge of blank 1, Fig. 3 is bent to form a tube such that recess 7 overlies the opening to and the projections 4 and 5 engage with slot 19 and edge 23 respectively, of blank 13, Fig. 4, the tongues 16 of which are bent to fit flush with the inside of the slotted tube formed from blank 1. The openings 10 and 17 in blanks 1 and 13 respectively lie in line under the edge of the bent portion of blank 1 so that the tongues 18 and 11 project towards each other to hold a compression spring 21 which presses the projection 4 to the extent of its movement in slot 19. In this position, the tongues 16 of the blank 1 may be moved to one side to allow a key hanger to be moved from an aperture 3, through which the enlarged head of the key hanger 26 may be passed, into an adjacent retaining slot 2 but return is prevented by the square edge of tongue 16. To remove the key hanger the locking tongues 16 are moved to one side against the pressure of the spring 21 by means of the push tab 20. The spring 21 contained in the overlapping recesses 10 and 17 is bounded on one side by the material of the key case, not shown, and on the other side by the recess 7 of the bent edge of blank 1. The holes 3 need not be offset provided the tongues 16 are shaped as shown in Fig. 9. Specification 712,221 is referred to.</p> |
