Definitions

  • the upper ends of the panels are supported by inclined legs hinged to the upper ends of the panels and the adjacent ends of the trampoline so that upon inward movement of the legs the entire trampoline is lifted off the floor and easily movable about on casters provided on the lower end of the legs.
  • a removable form of the backstop panels is disclosed as well as a removable gantry for use with the trampoline when employed as described in the foregoing patents.
  • the removable backstop panels include reinforcing yokes which prevent their collapse upon detachment from the trampoline.
  • the removable gantry transversely straddles the trampoline bed and is wholly supported upon the floor by casters at the lower ends of two pairs of upright gantry legs, the latter resiliently engaging means on the side frames of the trampoline in order to locate the gantry midway between the trampoline ends while permitting vertical movement of the trampoline independently of the gantry.
  • the chief object of present invention is to provide means by which a folding type of trampoline may be equipped with the backstops and with the gantry or barrier structure described in the latter two patents which are not only readily attachable and detachable with respect to the trampoline but which in addition also incorporate means by which the entire unit, including the assembled backstops and gantry, may be readily transported about the floor of a gymnasium.
  • the yoke merely lies atop the adjacent portions of the trampoline frame and when the backstop is demounted from the trampoline the yoke in effect forms a kind of fourth side for the backstop frame sufficient to prevent its serious bending or collapse.
  • Such supports have taken the form of two pairs of legs extending downwardly from the upper ends of the backstop frames to the ground or floor and suitably braced to the trampoline frame.
  • Each leg is of two telescoping sections so that the inclination of the backstops with respect to the trampoline bed may be adjusted.
  • the present invention also incorporates a modified form of such legs and braces whereby upon simple and quick movement thereof the entire trampoline, together with the backstops, may be lifted so as to be wholly carried by the legs which in turn are provided with casters or other suitable means at their lower ends. The entire apparatus can thus readily be moved from place to place on the gymnasium floor and easily lowered at any location for use.
  • the present invention incorporates a form of gantry which, instead of being carried on the trampoline frame proper, straddles the latter, being supported wholly upon the floor on casters and held in proper location only by virtue of its frame resiliently gripping the sides of the trampoline frame.
  • the gantry follows of its own accord on its casters.
  • the gantry frame engages the side members of the trampoline frame, it can be easily rolled on its casters and slipped off one end of the trampoline once the backstop at that end has been removed.
  • FIGURE 1 is an upper perspective side view of a trampoline equipped with demountable backstops and a portable gantry, all incorporating the features of the present invention
  • FIGURE 2 is an upper perspective view of one end of the apparatus of FIGURE 1 showing the same in its lowered or playing position;
  • FIGURE 3 is a View similar to that of FIGURE 2. but illustrating the backstop supporting legs in their position whereby the trampoline is elevated and the entire apparatus rendered portable;
  • FIGURE 4 is a detailed view showing an example of means by which the backstops may be demountably attached to the trampoline frame;
  • FIGURE 5 is a view taken along the line 55 of FIG- URE 4;
  • FIGURE 6 is a detail view showing one means by which the gantry may be located along the sides of the trampoline frame.
  • FIGURE 7 is a detail view showing one backstop demounted from the trampoline and carried on a stand for transport and storage.
  • FIG. 10 designates generally a trampoline of the folding type employing a rectangular frame 11 of flattened oval tubing having side members 12 and end members 13, side members 12 being suitably articulated at 12' in order to permit folding of trampoline in the manner disclosed in the aforesaid patents 2,969,124 and 3,116,809.
  • Frame 11 encompasses a trampoline bed 14 of interwoven strips of suitable fabric tensionally mounted within frame 11 by suitable resilient means 15, such as shock cord or extensible helical springs.
  • trampoline 10 may also be provided with auxiliary side rails 16 (see FIGURES 2, 3 and 6), also of fiattened oval tubing interrupted opposite each hinge point 12', cantilevered outwardly from and along side members 12 in order to provide platforms on which inactive performers may stand without interfering with performers on bed 14. Each such platform may be covered by suitable pads 17.
  • Trampoline 10 is supported upon a collapsible undercarriage generally indicated at 18 and hingedly attached to the underside of frame 11. Further details with respect to the structure of trampoline 10 and its undercarriage 18 may be found in the two patents 2,969,124 and 3,116,809 to which reference has already been made.
  • Trampoline 10 is equipped with a pair of backstops 20, inclining upwardly and outwardly from adjacent the ends of bed 14, each backstop 20 employing an inverted U-shaped frame 21 of flattened oval tubing similar to that forming trampoline frame 11.
  • Each U-frame 21 surrounds the upper end and two sides of a backstop panel 22, similar in nature to trampoline bed 14, and also tensionally secured to U-frame 21 by suitable resilient means 23 similar to those indicated at employed for trampoline bed 14.
  • the lower ends of backstop frames 21 are secured to their respective side members 12 of trampoline frame 11 so as to be easily and quickly detachable therefrom.
  • the securing means employed in the particular embodiment illustrated in the drawings incorporate at each lower end of U-frame 21 a pair of vertical plates 24 and 25 straddling the adjacent frame side member 12 and carried both above and below the latter.
  • the upper ends of each pair of plates 24 and 25 receive its respective one of the lower ends of U-frames 21 which is hinged therebetween on a transverse horizontal axis by means of a hinge pin 26 so that the inclination of each backstop with respect to trampoline bed 14 may be varied.
  • Below hinge pin 26 plates 24 and receive one end of a U-shaped reinforcing yoke 27, also of flattened oval tubing, which end is fixedly secured to plates 24 and 25 as by welding.
  • Each yoke 27 is generally congruent with and lies atop the adjacent portions of its respective frame side members 12 and their included end member 13 of trampoline frame 11 to the rear of its respective backstop 20.
  • the ends of each pair of plates 24 and 25 below trampoline frame side member 12 are provided with a pair of notches 28 extending horizontally inwardly from corresponding edges thereof.
  • Notches 28 receive a latch bar 29 extending therebetween just beneath their frame side member 12 thereabove and horizontally pivoted to plate 24, as at 30, so that latch bar 29 may be swung out of notches 28 sufficiently to permit backstops 20 and their respective reinforcing yokes 27 to be lifted from trampoline frame 11.
  • each latch bar 29 is fitted midway between notches 28 with a suitable hand screw 31 extending vertically therethrough to engage the underside of its respective frame side members 12, whereby the latter is clamped tightly between hand screw 31 therebelow and the end of reinforcing yoke 27 thereabove.
  • the upper end of each backstop 20 may be provided with a suitable pad 32 to protect the performers.
  • each backstop 20 with a horizontal bushing 33 fixed to the rear of each side member of U-frames 21 about midway therealong.
  • Bushings 33 permit the use with backstops 20 of supporting stands of the nature described in the aforesaid patent 3,116,809.
  • Each backstop 20 can be rotated downwardly about its hinge pin 26 so that it lies flat upon its yoke 27,
  • each bushing 33 is then engaged by the horizontal pintle 34 of a stand 35 whereupon, after releasing its latch bar 29, each backstop 20 can be carried off it end of frame 11 on its pair of stands 35. Thereafter, rotation of each backstop 20 upon the pintles 34 of its pair of stands 35 to the vertical position shown in FIGURE 7 permits easy transport and storage of same.
  • Each backstop 20 is supported at its upper end by a pair of legs 40, each composed of two sections of tubular material the upper of which telescopes within the lower, the latter being provided at its upper end with suitable clamping means operated by hand screws 41 so that the overall length of each leg 40 may be adjusted.
  • the upper end of each leg 40 is hinged at 42 to the upper end of its respective backstop 20 adjacent one upper corner thereof so that leg 40 extends downwardly and outwardly therefrom outboard of its adjacent end member 13 of trampoline frame 11 and may be move-d toward and against the latter about its hinge 42.
  • Legs 40 are provided at their lower ends with suitable means, such as casters 43, in order to permit movement of legs 40 in any direction upon the floor or ground.
  • Each leg 40 is connected in turn to trampoline frame 11 by means of a tubular brace 44 hinged at its upper end at 45 to the underside of the adjacent end member 13 of trampoline frame 11 and extending downwardly and outwardly therefrom to be similarly hinged to its respective leg 40 at 46, all so that leg 40 may be moved about its hinge 42 toward its adjacent frame end member 13 as aforesaid.
  • braces 44 correspondingly move about their hinges 45 and 46 to a more vertical position, whereupon it will be apparent that trampoline 10 is bodily elevated from the floor or ground with its entire weight being thence carried by braces 44, the portions of legs 40 below hinges 46, and casters 43.
  • the apparatus is thus converted from its playing position shown in FIGURES 1 and 2 to its transport or portable position shown in FIGURE 3.
  • An important derivative feature of casters 43 is that they effectively prevent walking of the apparatus when in its playing position. If legs 40 are not equipped with casters 43 but merely abut the ground, not only is portability lost but the entire apparatus tends to walk along the floor during play owing to the flexing of trampoline frame 11 and the various components of undercarriage 18.
  • each pair of legs 40 may also carry a secondary target structure in the form of a rebound net comprising an inverted U-shaped tubular frame 48 extending thereabove and closed by netting 49 loosely secured about frame 48. The latter may be telescoped into the upper ends of legs 40 or may, independently of legs 40, also be hinged at 42 so that frames 48 may be folded down against legs 40.
  • Gantry or barrier 50 is constituted from a pair of inverted, U-shaped tubular frames 51 straddling trampoline frame 11 transversely of bed 14 and midway along the latter.
  • U-frames 51 are laterally spaced from and parallel to each other by means of suitable horizontal struts 52 above trampoline bed 14 and incorporate legs 53 extending downwardly past the auxiliary side rails 16 of trampoline frame 11, their respective lower ends being joined by feet 54 carrying casters 55 which engage the floor or ground.
  • the upper end members 56 of U-frames 51 carry the respective ends of a horizontally disposed, open tunnel 57 having a reduced central section 58.
  • Tunnel 57 is located so that its axis extends longitudinally of and centrally between the sides of bed 14 and the upper area within each U-frame 51 surrounding one end of tunnel 57 is closed by suitable netting 59 in order to constitute gantry 50 a barrier to the passage of a missile therethrough except through tunnel 57.
  • the upright legs 53 of U- frames 51 are of a length sufficient so that the elevation of tunnel 57 is above the reach of a player standing stationary on bed 14. If desired, in order to adjust the height of tunnel 57, the legs 53 of U-frames 51 may be provided with adjustably telescoping portions in the manner of those for legs 40 of backstops 20.
  • Gantry 50 may be located with respect to bed 14 by any suitable means which will permit it easily to be removed therefrom on its casters 55.
  • the means illustrated are simple but effective.
  • the upright legs 53 of gantry 50 are formed with respect to end members 56 therebetween so that they resiliently engage auxiliary side rails 16 and are located therealong by means of a pair of tubular bars 60, each of which is cantilevered outwardly from its respective auxiliary side rail 16 and bent at its mid-portion to form a rounded nose 61 and a ramp 62 on each side of the latter extending horizontally outward from each rail 16.
  • Each pair of corresponding legs 53 of gantry frames 51 thus resiliently engage the ramps 62 and straddle nose 61 of a bar 60.
