n n Bi/@wwm [20 3 Miam 3,107,916 SPRINKLING JUMP ROPE Wiliiam A. Cooper, 1515 McKinley, San Antonio, Tex. Filed Nov. 3, 1961, Ser. No. 150,032 12 Claims. (Cl. 272-74) This invention relates to new and useful improvements in amusement and exercising devices, and in particular the invention concerns itself with a jump rope type device wherein an elongated member with substantially coaxial end portions and a bowed intermediate portion is caused to revolve about the axis of its end portions while a child, standing between the end portions, jumps over the bowed intermediate portion each time it passes close to the ground during its revolution.

The principal object of the invention is to materially improve upon a conventional jump rope of the character above outlined and to substantially increase the amusement and enjoyment derived from its use, this being attained by utilizing a perforated tubular conduit in place of the conventional rope and providing means for delivering water under pressure into the conduit so that it is discharged as a spray through the perforations of Ithe conduit to sprinkle the jumping child.

Several embodiments of the invention are disclosed, some of simple construction and others yof a more complex nature. Other objects and features of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, wherein like characters of reference are used to designate like parts, and wherein:

FIGURE l0 is a fragmentary sectional view of the open end portion of the conduit in the embodiment of FIG- URE `9.

Referring now to the accompanying drawings in detail, more particularly to FIGURES l-4 inclusive, the sprinkling jump rope in `accordance with the invention :is designated -generdly by the numeral 14 and comprises a tubular conduit 16 of rubber, plastic, or the like, which is substantially U-shaped in coniiguration, hav-ing a pair of substantially

coaxial end portions

18, 26, Iand a bowed intermediate portion 22. The intermediate portion of the conduit is provided with lateral orifices 24 Ifor spraying water delivered under pressure into the conduit, as will be hereinafter described, the water spray being indicated at 26 in FIGURE l.

The conduit end portion is secured by a clamp 28 on a tubular bushing 30 which is rotatably mounted on a tubular end portion 32 0f an L-shaped bracket 34, the latter having a at portion 36 which is lfastened by a clamp 3',i-7,9lb Patented Oct. 22, 1863 38 to a suitable support, as for example, an upright standard or pole 40. The material of the conduit 16 may be suiliciently stift` for the conduit to sustain its U- shaped coniiguration by itself, but if not, a reinforcing wire or rod I42 may extend longitudinally lthrough the conduit for sustaining the shape thereof. As shown in FIGURE 4, the diameter of the rod 42 is substantially smaller than the inside of the conduit, so that the rod does not materially interfere with passage of water through the conduit. An'end por-tion `of the rod 42 projects outwardly -from the end portion 20` of the conduit into the bracket 34, where it is rotatably journalled in a suitable bearing, as at 44. It is to be noted that in the rotatable mounting `of the conduit portion 20 on the bracket 34 4as described and shown in FIGURE 2, the bracket 34 provides a closure for the end portion 20 of the conduit so that water cannot leak from the conduit at that end.

The other end portion 18, which may be referred to as the open end of the conduit, is secured by a clamp 46 on a a tubular end portion 48 of a hollow crank 50, the other end of the hollow crank being closed by a suitable hand lgrip l52 which is provided thereon. The crank 56 is rotatably journalled in a bearing 54 provided in a cross bar 56, the latter having vdepending legs "58 which are slidably Vdisposed in a pair of vertical tubes 6l) secured to a suitable base 62. The base 62, the tubes `60, the legs 58 and the cross bar 56 thus constitute a supporting frame for rotatable mounting of the crank 50 yand the height at which the crank is disposed may be varied by sliding the legs 58 in the tubes 60 and subsequently locking the legs against sliding by suitable set screws 64 provided in the upper end portions of the tubes. The end portion of the reinforcing rod li2 projecting from the end 18 of the conduit 16 may pass into the crank 50, as shown in -FIG- URE 3, so that when the crank is rotated, the conduit will be rotated therewith without imposing undue strain on the attachment of the conduit portion 18 to the crank portion 48 by the clamp 46.

Water under pressure is delivered to the conduit 16 by a llexibleY hose 66, for example, a garden hose, provided with a coupling 68 which is connected to one arm of a T 70. The latter is rotatably positioned on the crank V50 through a plurality of apertures 76 formed in ing 54 and is prevented from endwise displacement thereon by a pair of keepers 72. The T 70 encircles the crank 50 in spaced relation so as to form an annular chamber 74 and the latter communicates with the interior of the crank 58 through a plurality of apertures 76 formed in the crank. Suitable seal-ing rings 78 are provided in the T 70 to prevent leakage, and it will be apparent from the foregoing that with the hose 6'6 land the T 70 remaining relatively stationary, the crank 50 and the conduit 16 may be rotated while water is delivered Ifrom the hose through the T and throughV the crank to the conduit, for spraying therefrom through the orifices 24.

The embodiment 114 of the invention is intended to be used by at least two players or participants, one of whom turns the crank 58 while the other jumps the revolving portion 22 of the conduit. FIGURES 5-8 illustrate a modified embodiment which is designated generally by the numeral 80 and is somewhat simpler than the embodiment 14. In the embodiment 80 the substantially

coaxial end portions

82, 84 of the conduit 86 are secured in tubular sleeves 88, l90, respectively, on which are rotatably mounted tubular hand grips 92. The conduit 86 is apertured `as at 89 and a reinforcing rod 94 may be provided in the co-nduit, if so desired or necessary for the conduit to retain its U-shaped configuration. One end of the conduit is closed by the provision of a plug 96 in the sleeve 90, while the sleeve `88 at the open end of the conduit is provided with an adapter 98 to which the water delivery hose 100 is `connected by a rotatable coui pling 102. The embodiment 80 is intended to be used by at least three participants, two of whom hold and manipulate the handles 92 at the ends of the conduit while the third is jumping. Provision of the rotatable coupling 102 permits revolution of the conduit while the hose i) remains relatively stationary.

A stil-l lfurther rnodiied and simpler embodiment of the invention is illustrated in FIGURES 9 and l0- and designated generally by the numeral 110. In this embodiment the conduit 112 has hand .

grips

114, 116 molded or otherwise immovably provided on its end portions, the end of the conduit in the hand grip *116 being closed and the open end of the conduit in the hand grip 114 communicating with an adapter 11S. The latter is ernbedded in the hand grip v114 and projects outwardly therefrom for non-rotatable connection to a water delivery hose 120. A reinforcing rod is not provided in the conduit 112 and the material of the conduit is -iiexible in a rope-like manner so that it may be manipulated in the nature of a conventional jumping rope when two persons are holding the

hand grips

114, 116, as shown. While the hand grips are not rotatable on the end portions of the conduit and Awhile the hose 120l is non-rotatably connected to the hand grip 114, the iiexibility of the conduit is sufficient to permit it to be revolved through several turns without harmful twisting or translated through a revolving orbit without any twisting or axial rotation of the conduit at all.

While in the foregoing there have been described and shown the preferred embodiments of the invention, various other modifications may becorne apparent to those skilled in the art .to lwhich the invention relates.
