DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in detail, and in particular to FIG. 1 thereof, the jumping apparatus 10 of the invention, as depicted therein, includes an elongated arm 12, a series of depending tabs or flaps 14 pivotally connected to arm 12 and an attaching and adjusting bracket assembly 16. Assembly 16 is connected to one end of elongated arm 12, and attaches jumping device 12 to a support member.

Jumping apparatus 10, when in use is normally positioned in an operative position similar to that shown in FIGS. 1 and 7, but may be positioned when not in use in an inoperative position similar to that shown in FIG. 5. To maintain apparatus 1-0 in a non-use inoperative position, such as depicted in FIG. 5, the apparatus is pivoted upward about attaching bracket assembly 16 and held in a nearly vertical position by a hook 18, attached to the supporting member by means of a chain 20 or the like, engaged within an eye 22 secured to arm 12 adjacent its lower inner-end portion. Upon release and disengagement of hook 18 from eye 22, device 10, and in particular elongated arm 12 thereof, may be rotated to an operative in-use position such as indicated in FIGS. 1 and 7.

Jumping apparatus is particularly adapted for use in conection with a -basketball basket 24 and backboard 26 therefor as depicted in FIGS. 1 and 5. The basketball backboard 24 is usually supported from above by a pair of circular support columns or pipes such as 28 and 30. Jumping device 10 is readily connected to and mounted on one of these circular supporting columns or members such as 28, and extends outward therefrom in a direction opposite to basket 24 in a plane generally parallel to the plane of the backboard 26. Jumper 10 may also be readily attached to and mounted on a generally vertical, at support surface or member, such as a wall 31 or the like, as depicted in FIG. 7. The apparatus of this invention may be used either indoors or outdoors with the same being readily mountable on any generally vertical, circular or flat supporting member or surface.

Elongated arm 12 includes an outer upper end portion 32 and an inner lower end portion 34 with arm 12 being continuous and uniform throughout its total length extending between these end portions. Arm 12 can be of any desired and conveniently workable length, as for example six feet and may be constructed from hard wood, a relatively light weight metal or the like. The arm 12 should be of uniform width and thickness throughout its entire length and is miter-cut along its inner edge or end 36 to permit pivoting and adjustment thereof as will be explained more fully hereinbelow.

Tabs or flaps 14 are thin and flexible, and preferably made from a plastic or other like material. These flaps 14 are of uniform size and thickness, particularly being uniform in their width and length dimensions, and preferably might be of a width of two inches and a length of six inches. Each tab or flap 14 is provided with an opening or passageway 38 extending therethrough adjacent the upper end portion 40 of the tab to permit the same to be attached or mounted to arm 12. Each of tabs 14 is connected to or mounted on arm 12 at equidistant, uniformly spaced points therealong by means of a screw 42 extending through opening 38 of the tab and into an appropriate opening 44 within arm 12. A suitable washer 46 is provided between the head of screw 42 and flap 14. The connection of each tab 14 to arm 12 is a freely pivotable connection such that tabs 14 and in particular the lower end portions 48 thereof are permitted to freely hang vertically downward from arm 12, no matter what the vertically positioning of the arm may be. Since tabs 14 are freely pivotable about their connection to arm 12, always depending generally vertically downward therefrom due to the force of gravity, it is possible that tabs 14 will at times assume a position generally in alignment with the longitudinal axis of arm 12, as is generally the case as depicted in FIG. 5 when arm 12 is in its inoperative generally vertical position. When jumplng apparatus 10 is used in conjunction with a basketball basket as depicted in FIG. l, it is often advantageous to position the lower end portion 48 of one of tabs 14 at the same height or level as the top of basket 24, and mark that particular tab 50 accordingly. This height or vertical d1- mension from the floor 51 to the lower end portion of tab 50 and the upper edge of the basketball rim 24 is depicted in FIG. l by the doubleheaded arrow or dimensionline at reference numeral 52.

Bracket or attaching arrangement 16 includes a lower supporting or reinforcing metal member 54 having a portion 55 extending along the lower edge of inner end portion 34 of arm 12 to a bend 56 therein, and then continues downward therefrom in portion 57 along the continuation of miter-cut end 36. Also provided is an upper reinforcing or supporting metal member 58 including a portion 59 extending along the upper edge of lower end portion 34 of arm 12 to a bend 60 therein, and then continuing downward in portion 61 along the inner miter-cut edge 36 of arm 12 and along downwardly extending portion 57 of lower supporting member 54, terminating adjacent the lower end thereof. Lower end portion 34 of arm 12 is positioned between lower and upper supporting or attaching members 54 and 58, and connected thereto by means of threaded bolts 62 and 64 extending through openings within lower member 54 and openings within arm 12 and being secured within threaded openings within upper attaching member 58. An opening 66 extends through downwardly directed portions 57 and 61 of respective attaching members 54 and 58, which opening 66 threadedly and engagingly receives a threaded bolt 68 extending therethrough to adjust and vary the angle between arm 12 and supporting member 28. Bolt 68 is provided with a locking nut 70 to lock and prevent rotation thereof after the same has been adjusted to the desired position. Assembly 16 further includes a curved or circular attaching plate 72 which is positioned against circular support member 28 for placement and attachment of the entire apparatus thereto. Plate 72 is attached to support member 28 by a pair 74 and 76 of flexible metal band clamps. Each of clamps 74 and 76 is provided with an adjusting and tightening bolt arrangement 78 whereby the clamp can be adjusted and tightened around supporting member 28 to secure plate 72 and the jumping apparatus thereto. A pair of spaced generally parallel plate members 80 and 82 extend outward from curved attaching plate 72 and are connected thereto. The arm 12 is connected to and pivotally attached between plate members 80 and 82 by means of a bolt 84 and nut 86. Bolt 84- extends through appropriate openings within the upper portions of members 80 and 82 and through an opening 88 provided within lower end portion 34 of arm 12 in a position closely adjacent curve 60 within upper supporting and attaching member 58. In this manner elongated arm 12 is freely pivotable about bolt 84 extending through lower end portion 34 of the arm and through members 80 and 82. By proper adjustment of bolt 68 the distance between plate 72 and downwardly directed portion 61 of supporting member 58 can be varied such that arm 12 is pivoted about bolt 84 to vary the angle between arm 12 and support 28.

Jumping apparatus 10 can be readily adjusted and moved upward or downward along supporting member 28 by loosening clamps 74 and 76 and then moving plate 72 and the apparatus attached thereto upwardly or downwardly along member 28 to the desired height or position of the apparatus therealong, thereafter clamps 74 and 76 are retightened to firmly position and secure device 10 to support 28. The height increment or vertical distance between the lower ends of each of the adjacent depending tabs or aps 14 can be adjusted, if so desired, by simply changing and adjusting bolt 68 to vary the angle between elongated arm`12 and supporting member 28. In this manner the difference in heights of the lower ends of adjacent flaps 14 and the various increments therebetween could for example be one-half inch, one inc-h, two inches, etc. as may be desired. If desired, indicia, as at reference numeral 53, may be placed on the individual tabs 14 to give their actual height above the surface of the floor or ground, and new or different sets of tabs 14 may be readily exchanged with those existing on arm 12 when the angle between arm 12 and support 28 is changed, by means of adjustment bolt 68 to give different height increments between individual adjacent tabs 14, or when the entire apparatus 10 is moved upward or downward along support member 28.

When the apparatus 1t) is positioned on and attached to a flat vertical support member, such as wall 31 as depicted in FIG. 7, the mounting bracket 90 as depicted in FIG. 6 is used. Bracket 90 is provided with a pair of openings 92 and 94 positioned within the mid-portion of bracket back 96 and closely adjacent respective upper and lower end portions 98 and 100, for attaching bracket 90 to at surface 31 by a pair of screws passing therethrough. The outer side portions 102 and 104 of bracket 90 are turned and bent forwardly and inwardly of bracket back 96 to provide grooves or channels respectively at 106 and 108 within which outer side portions 110 and 112 of curved attaching plate 72 may respectively tit to become attached to bracket 90. Outer side portions 110 and 112 are respectively positioned within grooves or channels 106 and 108, being slid downwardly thereinto from above, and abut or engage respective stop members 114 and 116 provided on bracket back 96 closely adjacent lower end portion 100 thereof. Bracket 90 is normally permitted to remain attached to at vertical surface 31 such that apparatus can be readily attached to and removed therefrom without the aid of further connecting means.
