the laces have been opened. I am aware of the existence of means for thatv purpose, but the known means constitute a continual reinforcement of the lace ends, and cannot be attached to the ends of the ordinary laces as are generally inserted into the eyes of boots and shoes.
Now, the present invention relates to an attachable and detachable grip-forming head for the laces in question, and this head is so designed that the lace end is automatically retained in the head. This latter is hollow and the aperture at its free end is larger than the other aperture through which the lace is to be introduced into the head, and the shape. of the space or chamber between said apertures, in the interior of the head, is such that when the lace has been bent rearwardly it is held fast in the head chamber, the more so as the pull to which the head may be subjected is increased. The outer shape of the head may be as desired. Two constructional forms of this improved lace end head are illustrated diagrammatically and by way of example on the accompanying drawings on which, y
Figure 1 is an axial section through one of these forms, without a lace,
Figure 2 is a similar view, showing the head attached to a lace end,
Figure 3 is a plan of the head,
Figure 4 is a view similar to Fig. 2, but showing a modification, and
Figure 5 is a plan of this modification,
Referring to Figs. 1-3, this lace end head is designed as a hollow truncated cone provided at its-narrow end with a cylindrical bore 2, and at its other end where it is closed with two bores 3, the diameter of which cor responds practically to the diameter of the lace 4 which is a cord in this case. The lace or cord is introduced through the bore 2 and then passed through one of the bores 3, thereafter its projecting end is then bent rearwardly and passed through the other 898,448, and in Germany October 11, 1928.
bore 3 into theinterior of the head. The end 5 of the lace 4 is rigid, as usual, and as this end proper cannot be bent round from the one bore 3 into the other bore 3 by reason of its stifiness and the great resistance thereby produced the head 1 cannot be detached from the lace merely by being pulled, but prior thereto the lace end may-be withdrawn from the head, whereafter it is quite easily possible to detach the "head from the lace.
In the other constructional jform shown also byway of example in F igsr and 5 "the head has only one continuous conical bore 3, the diameter of which, especially at its narrow end, is such that the lace portions forming the inverted U-. are firmly pressed one against the other when the head is subjected to a pull whereby then the secure connection between the head and the lace is ultimately established. Disconnecting the head from the lace is also in this case performed by withdrawing the U-portion of the lace from the head, through the wider end of the same, whereafter the lace can be straightened and the head removed.
1. A detachable head for the free ends of V laces, lace cords and the like, comprising a stifi'enedend on the lace; and a grip-forming body having a bore therein with two open- 30 ings, one opening being adapted to receive the stifiened end of, the lace and the other opening the soft part thereof whereby 'a pull on the soft part will automaticallyretain the lace in the body due to the openings and the stiffened end.
2. A detachable head for the free ends of laces, lace cords and the like having a stiltcned end, comprising a grip-forming body having a pair of bores therein, one bore being adapted to receive the stifi'ened end of the lace and the other bore the soft part thereof, whereby a pull on the soft part will automatically retain the lace in" the body due to the bores and the stiffened end.
3. A detachable head for the free ends of laces, lace/cords and the like having a stiffened end, comprising a grip-forming body having a boretherein in one end and a pair of bores in the other end, the first-mentioned bore being adapted to receive the soft part of the lace, one bore of the pair thereof being adapted to receive the soft part of the lace and the other bore of the pair being adapted to receive the stiffened end of the lace Whereby a pull on the soft part will automatically retain the lace in the body due to the bores and the stifi'ened end. v
