United States Patent M 3,104,659 SAFETY LEADERS Josephine Grahling, 3562 $9M Center Road, Cleveland 24, Ohio Filed July 31, 1961, Ser. No. 128,027 14 claims. Cl. 119-96) This invention relates to safety devices or leashes by means of which older persons generally indicated as adults are able to maintain control over children as while walking or shopping. Various types of restraining devices have been devised for controlling and limiting the travel of children in relation to supervising adults. Essentially such devices comprise a cord, strap or chain one end of which is connected to the child as by a band or harness and the other end of which is held by or fastened to the person of the adult. Reference is made to my copending application for United States patent Serial No. 748,266, filed July 14, 1958, for Safety Leader, now Patent 2,994,300, dated August 1, 1961, of which the present application is an improvement.
:In accordance with one aspect of the present invention and as a principal objective the connecting or leash element is provided in the form of a suitable leader, preferably a resilient member which is connected to the child in such a way as to discourage disconnection by the child. a
More specifically it is sought to provide a wrist or other band for attachment about the person of the child, the band having a locking type buckle with an eye in its tongue which prevents the buckle from being opened or disengaged when a locking element such as a snap hook or spring loaded snap ring is inserted in the said eye.
Supplementing the snap locking connection and as a further objective, there is provided, in combination with the snap connection arrangement, a relatively short flexible element or chain connected to a ring fast to the band. Such supplemental connecting chain, in combination with the snap connection arrangement provides for alternative close coupled restraining connections between adult and child.
A further object is to provide a control device of the character mentioned which can be quickly converted be tween a long leash connection and a close coupled connection.
A still further object is to provide a safety leash for children which allows a relatively wide latitute of movement of the child away from the adult without danger of the leash becoming tangled or tripping the adult or the child when the two persons are close together; more particularly to provide a device of the character referred to which includes a resilient leader or leash element to progressively increase the restraining force exerted by a sudden pull without producing an undesirable jerk or shock to the child or to the restraining hand of the adult and which will return to its normal length when the tension has ceased, thereby allowing maximum freedom of any movement for both the child and its supervisor.
Other objects and advantages will become apparent in the following detailed description of preferred embodiments representing the best known mode of practicing the invention. This description is made in connection with the accompanying drawings forming a part of the SPBClfi? cation.
In the drawings:
FIG. 1 is an illustration of the safety leash device partly in section, showing the bands adapted to be placed about the persons of the guardian or adult and the child, the flexible elastic leash element which connects the bands, the close coupling chain and the snap element locking connector;
FIG. 2 is a fragmentary view corresponding to a portion of FIG. 1 and enlarged relative thereto, showing a Patented Sept. 24, 1963 modification of the childs strap, the fragmentary view illustrating the use of a spring loaded snap ring as an alternate connector for the snap hook and also the use of a ball chain instead of the link chain, both as shown in FIG. 1;
FIG. 3 is another fragmentary view corresponding to another portion of FIG. 1 showing a modification of the guardian s strap in which the swivel connection has been eliminated and the flexible leash element is threaded through the metal ring, brought back and clamped upon itself to [form a permanent loop by insertion in a sleeve which is then clamped firmly together; and
FIG. 4 is a fragmentary view corresponding to the right hand end portion of FIG. 1 showing a further modification of the guardians end of the device, inwhich the wrist strap and swivel have been eliminated and the flexible leash element is formed into a loop of suflicient size to permit the grasping by, or insertion through of a mature hand. The method employed in forming the end loop being the same as in the modification of FIG. 3. A ring for the short chain connection is provided by the insertion of the leash element through the ring before forming the hand loop.
The device in its more complex form comprises a pair of flexible and substantially inextensible bands 1 and 2 connected by a flexible and elastic leash element 3. The first band 1 is designed for attachment to the adult or guardian, as by encirclement of the wrist, and the second band 2 is designed for attachment to the child or ward, also as by encirclement of the wrist. These bands are formed of flat strip leather or plastic material. A conventional buckle 4 is provided to join the ends of the adults band 1, the bucklehaving a cross bar received in a reverse bend 7 formed at one end of the band and havinga tongue 5 receivable in any one of a number of holes 6 formed at spaced intervals in the band to permit adjustment of the band size. The reversely bent end 7 of the band also receives and retains a split ring 8 for attachment of one end of the leash element 3 as by a swivel assembly comprising a socket ring 9 and a pin ring 10. The ring 9 has a radial aperture through which is rotatably received a radial pin integrally formed on the pin ring 10, the pin being headed as at 11 inside the ring 9 to hold the rings captive together. In assembly, one of the rings, as the ring 9 is interlocked with the hand ring 8 by passing it through the split in the latter before the ring 8 is fastened between the runs of the flexible band loop 7. These runs are held together as by rivets or stitching, not shown, on both sides of the ring 8, the split of the latter being located between the runs of the flexible band and therefore not shown in the drawings. The leash 3 may thus turn relative to the ring 8 and the band 1, the end of the leash element being passed through the rotatable swivel ring 10, bent back upon itself and secured as by a compression fitting 12 in the provision of an end loop or eye 15. i i
The childs band 2 is similar to the adults band 1, its size being adjustable by means of a conventional buckle 17 having a tongue 18 receivable through any one of a number of holes 19 formed at spaced intervals in the other end portion of the band. Loop 20in the end of the band for securing the buckle 17 and corresponding to the end bend or loop 7 in the wrist band 1 for the adult also and similarly receives and secures a metal ring 21 which constitutes a principal point of connection between the leash element 3 and the childs band, as will appear. 1
The end loop in the wrist band 2 is suitably secured as by stitching or rivets, one such rivet being shown at 28.
The leash element 6 is of a flexible cord-like design incorporating an extendable elastic cord of rubber, or
material of like characteristics and properties, having suitable tensile strength for the desired usage and enclosed in a sheath, preferably of a woven water resistant fabric, said sheath being stretchable in a manner to conform to the extension and retraction of the core and also by the use of color and pattern to provide an attractive appearance to the invention.
The leash element 3 may to advantage comprise a rubber tube having, if desired, a woven fabric sheath which not only protects the rubber but also permits the use of attractive colors and designs in decoration of the leash. In order to provide effective restraint of a child of normal weight and of an age from about two to about five yea-rs, the leash, without being strained to its elastic limit, yields to the stressessuch a child normally imposes thereon in its efforts to assert its independence. For example, in contemplated use to restrain such a child the leash 3 is of such resiliency and strength as to exert a contracting force of from about two pounds to about four pounds, preferably of the order of about three pounds, when stretched to twice its unstressed length.
The leash element 3 is attached to the childs band or strap 2 in a similar manner as used at strap 1, by means of leash attaching split ring corresponding to the ring 8 of the guardian adults band 1, a swivel assembly comprising socket and pin rings 24, 25 corresponding respectively to the socket and the pin rings 9, 10, pre viously described, and loop 26 and compression fitting 27 corresponding respectively to the loop 15 and the compression fitting 12, previously described.
A supplemental or secondary connection between the leash element 3 and the childs band 2 at the childs end of the leash is provided by a relatively short flexible chain or similar tensile element 33. This element is connected at one end to the metal ring 21 and at its other end to the eye 22 of the buckle tongue 18 as by snap hook 23 having spring lock 29. Swivel 36 is interposed between the snap hook 23 and the corresponding end of the chain 33 to prevent twisting and kinking of the chain when connected to the ring 8 of the adults band in achieving a close-coupled connection. In normal use the snap hook 23 is inserted through the eye 22 in the locking element or tongue 18 of the buckle 17 thus providing an interlocking connection or a safety lock for said strap 2.
Another use for the chain is to provide a close coupled and nonextendable restraining connection between the two individuals, this is accomplished by removing the snap hook 23 [from the buckle eye 22 and hooking it onto the ring 8 on the adults strap 1. Thus an additional safety precaution is created by such interlocking connection of the supplemental chain element as when crossing streets and also when deemed desirable in other situations. In this close coupled arrangement the two straps 1 and 2 are connected directly and in swivel relationby the short chain 23 and the flexible leash element 3 is suspended in a festoon. As a safety feature, the bands 51, 2 remain connected in the transition period when the snap hook 23 is removed from the buckle 17 of the childs band and before it' received on the ring 8 of the adults band; the possibility of the child dashing away from the adult while temporarily unhooked is thus eliminated.
A still further use for the chain is to provide means for restricting the childs movements apart from the adult as when it is desired to leave it unattended for short periods. This is accomplished by disconnecting the strap '1 rfnom the adult, passing either it or the leash 3 around a fixed anchorage such as a post, railing, shopping cart handle or any other suitable convenient object and by attaching the snap book (23 to the ring 8 on the strap 1. Thus a closed encirclement is formed around a restraining structure which will restrict the child and permit either a limited freedom of movement within the stretchable limits of the leash element 3 if the latter is used to encircle the restraining structure or anchorage post or object or, if the guardian band 1 is used asthe encirclement about the restraining structure or anchor- 5 age, substantially no freedom of movement.
Thus the combination of the relatively short tensile element or chain 33 and the relatively long elastic leash.
element 3 has a number of advantages in use- When connected as shown in FIG. 1 the chain 33 provides a safety feature in that disconnection of the band 2 by the child or through inadvertence is avoided. When the child is close coupled by the chain 33 directly to the carriage or other article or anchorage, the leash element 3 hangs in a loop from the rings 8' and 20 to which both the leash 3 and the chain 33 are coupled. In effecting a connection of the child directly to an anchorage as by the snap hook 23 the child is at no time free to escape,
being continuously connected by the leash element 3 to the band I]. about the wrist of the adult while the adult is releasing the hook 23 from the buckle 17 and reconnect ing such hook to the anchorage.
FIG. 2 illustrates a modification of the invention where- I in, in lieu of the bentwire chain 33 shown in FIG. 1,
the close coupling and safety arrangements previously the end of the ball chain 43' as by means of an end link 47 formed with an aperture through which the ring 44 is received. The other end of the ball chain43 is attached to the ring 21 of the wrist band 2 by suitable means not shown.
FIG. 3 shows a modification wherein the end loop 15 of the flexible leash or leader element 3 is connected directly to the split ring 8 of the guardian adults wrist band 1, this arrangement eliminating the swivel assembly comprising the rings 9, 10 of the FIG. 1 arrangement. In this modification the swivel assembly'comprising the rings 24, 25 at the childs end of the flexible leash 3 is retained.
In another modification, not shown, the loop 26 on the childs end of the leash or leader element 3 is directly connected to the childs wrist band ring 21 similarly to the manner in which, in the previous modification, described in connection with FIG. 3, the adults end of the leash or leader 3 is connected directly to the wrist band ring 8 without the swivel assembly. When the childs end of the leash or leader is thus connected directly to the childs wrist band without the swivel assembly, the other or adults end of the leash or leader may have the swivel assembly 9, 10 or, if desired such swivel assembly may be eliminated, providing a still further modification wherein swivel connections at both ends of the leash or leader are eliminated.
FIG. 4 shows a further modification wherein the guardian adults wrist band 1 is eliminated, the guardians end of the flexible leash or leader 3 being provided with a.
large loop 40 adapted to be received over the wrist of the older person or guardian. The loop 40 is formed by reversely bending the end portion of the flexible elastic leader or leash 3 and securing the end as by a compression fitting 41 corresponding to the compression fittings 12 and 27 shown in FIG. 1. The stretchable elastic nature of the sheathed filaments of which the leash or leader element 3 is formed allows the Wrist loop 40 to be stretched or enlarged in placing it over the guardian's wrist or in attaching it to any suitable object as an anchorage for restraining the child. The inherent resiliency of the filament material comprising the loop 40 causes it to 5. contract about the wrist of the guardian or about the anchorage to which it is applied. As a further refinement of the embodiment shown in FIG. 4, the element comprising the loop 40 is first passed through a relatively small metal ring 42 about /2 inch in diameter or less, before the end of the leash element is secured in the compression fitting 41 to secure the loop. Thus the metal ring 42 is held captive on the loop 40 and serves as a convenient means for attaching the snap hook 23 to the loop 40 in close coupling the child to the guardian adult or a siutable anchorage.
Thus the present invention provides a generally improved safety leash or leader combination by means of which an older person or adult is able safely and easily to control the movements of a small child. The device combines a relatively long leash element that resiliently resists elongation with a relatively short flexible and in extensible chain, or equivalent, the short chain normally being connected as a safety lock between the eye of the buckle on the childs wristband and the wrist band ring to which is attached also the adjacent or childs end of the flexible elastic lea-sh element. Such connection of the short chain to the buckle of the childs wrist band is independent of the main connection of the adjacent childs end of the flexible leash element to the childs Wrist band and is adapted for facile removal and replacement. By this arrangement the childs band can be closely coupled to either the adults band or to any suitable object, using the same snap hook 23 that normally connects the flexible leash element 3 to the childs band 2.
The embodiments described are by way of illustration, it being apparent that various changes in structural details, particularly with respect to the construction of the bands and the connections of the extensible leash element, may be resorted to without departing from the fundamentals of the invention. It is intended that the patent shall cover, by summarization in the appended claims, all features of patentalble novelty residing in the invention.
