This invention relates generally to improvements in gymnasium equipment and apparatus, andr-nore particular ly to an improved foldable basketball backstop.

It is an important objective of the presentimproyements tO- realize a ceilirig-suspended backstop. apparatus that may be readily lowered to a normal operative position, and: quickly and easily raised to a substantially horizontally folded, inoperative position.

Anotherimportant objective is realized bythe provision Of-a truss structure that is particularly adapted .to be swung forwardly upwardly from the normal operative position to a folded, inoperative position. This type of ceilin g suspended forward swingup backstop is frequently utilized Where. something in the nature of a gallery, balcony or the like is in fixed position between the backstop. and the Wall, or Where walls must be kept clear for hand-ball or other similar uses.

Still another important object is achieved by the arrangement of: the truss elements which provides a durable, extremely rigid backstop in its lowered operative position, and which enables the hinge connections of a toggle brace and of a drop member to be broke-n so as to permit the elements-to be raised to a horizontally folded position.

Yet another important object is realized-by an arrangement of a plurality of pulleys and an interconnecting cable or linefwhich coacts-with the structural arrangement of the front folding truss to provide the above noted advantageous result.

Another objectofthe invention is to proyide a backstop apparatus-which isdurable in construction and which can be economically manufactured and easily assembled;

The t'oregoingand numerous other objects and advantages. of thefinvention Will more clearly appear-from the following detailed description 05 apreferredembodirnent, particularly when. consideredin, connection with the 3Q0H Pflnying drawings, irr which:

The upper and lower drop portions; 16;,and i! are hingediy connected as at 20 Fig. I, while the upper drop portion iii is pivotally connected to supporting frame 11.

More Particularly, the upper drop portion 16 includes

opposite side bars

21 and 22, asis best shown I-Tig. 2, and cross bracing elements 23 interconnecting

side bars

21 and 22. A cross bar 24. bridges longitudinal bars 13 of the rame structure, and is attached thereto. The bar 24 may be considered a part of the supporting tran e it. The upper ends (Fig. 2) of

side bars

21 and 22 are pivotally connected, as indicated at 25, to cross-bar 24.

Similarly, the. lower-drop portion 17 consists of opposed side bars 26.and.2-7 (Fig. 2)., and of crossbraci-ngelements The side bars 26 and 27 are hingedly connected to the side bars 23. and 22- of upper drop portion 16 by bridging hinge rod 31. in the lowered extended position of the foldable truss structure, the drop portions 16 and 17 are alignedin a substantially vertical position. i i

A. rigid brace member referred to generally at 32 (Fig, i) normally extends rearwardly at an angle from said drop member 15, and is pivot-ally connected to the lower drop portion 1 7 and to the supporting frame structure. 1E. The brace member 32 includes opposite side bars 33, and intermediate bracing elements 3,4, as is shown in. Fig. 2.

Describing more in, detailthe structural connection of brace member 32 with the lower drop portion 17'and frame structure 11, it will be notedin Fig. I that an extension 35 projects rearwardly from the lower end of drop portion 17, and more particularly from each side bar 26 and. 27; These extensions 35 may be properly CQIlfidcLed a part of lower drop portion 17'. Another extension, extends downwardly-from each longitudinalbar lfiiand is located considerably to the rear of drop member 15, These extensions as may be considered a part ofiframe structure 11. Thus it is seen that side bars 33 o f brace member 32 have one of their ends pivotally connected as at 37 to extension 36, and have the opposite'nds pivotally connected as at it) to extension 35; As will appear more clearly from a later description, the extensions 35 and 36 permit drop portions 16 and 17 bracemember 32 to lie in a substantially horizontal folded position, when raised. V

Located at each side of the apparatus and between drop member 15' and brace member 32 is a tog gle referred togenerally in Fig. l at all. The toggle brace 41

consists'ot arms

42 and 43 hingedly connected by-roci 44, the rod 44 serving as av common hinge connection, and hence serving as a bridging piece. Arms .42 of 531? b fi tl f. ar -piv t y.

The actuating mechanism consists of a plurality of pulleys and an interconnecting line arrangement. One pulley 50 is fastened to a brace bar 53. of lower drop portion 17, the pulley being located below toggle brace 41, and located substantially centrally between side bars 26 and 27. Another pulley 52 is mounted to a cross bar 53 attached to and bridging longitudinal bars 13, the pulley 52 being located substantially intermediate extensions 36. The pulley 52 is located above toggie brace 41, and is located rearwardly of pulley St). A third pulley 54 is fastened to ceiling 19, and is located forwardly of and above the first pulley The pulleys 50, 52 and 54 are arranged and aligned in substantially thesame vertical plane. An actuating line 55 is passed over pulley 54, extends under pulley 5d, extends over pulley 52, and thence is connected to toggle brace 41 at its hinged connection 44.

When the forward end 5d of line 55 is pulled in the direction of the arrow shown in Fig. 1, the line and pulley arrangement serves to break the hinge connecions of the toggle brace 41 and of the drop portions 16 and 17, and acts to raise the truss structure from the extended, lowered position shown in Fig. l to the fully folded, retracted position shown in Fig. 4.

It is believed that the function and operation of this suspended type of front-folding basketball backstop apparatus has become fully apparent from the foregoing detailed description, but for completeness of disclosure, it will be noted that in the normal extended operative position, the drop portions 16 and 17 are aligned in a substantially vertical position, and that the toggle brace 41 is extended in its locked position. in this locked position, the

arms

42 and 43 of toggle brace 41 are moved slightly past the aligned arrangement to prevent unintentional or accidental breaking of the hinge connection.

Assume that the truss structure is in the normally extended operative position of Fig. l, and that it is desired to raise the truss structure to the inoperative folded position. Then the end 56 of line 55 is pulled in the direc tion shown by the arrow (Fig. 1). For convenience, it is possible to utilize a winch operatively connected to a power means (not shown) to actuate line 55. When line 55 is pulled as described above, the line acting through the pulley arrangement will first act to break the hinge connection of toggle brace 41 and the hinge connection of drop portions 16 and 17, as is shown in Fig. 3. It will become apparent that the force supplied through line 55 continues to fold toggle arms 42 and i 43, and at the same time, acts through toggle brace 41 to fold drop portions 16 and 17. Simultaneously, a component of this force acts through pulley Stl to raise direct- 1y lower drop portion 17. Thus it is seen that both

pulleys

50 and 52 act with line 55 to fold the truss structure.

When the truss structure is moved to the fully folded position, the component parts are disposed as shown in Fig. 4. Actuating line 55 acting through toggle brace 41 not only serves to fold toggle brace 41, but also aids in moving drop portions 16 and 17 to the folded horizontal positions shown in Fig. 4. Extensions 35 and 36 are of such length as to permit this result. It will be also noted that longitudinal bars 13 of supporting frame 11 are vertically spaced from ceiling for a distance to permit the goal hoop 47 to be received therebetween.

To lower the truss structure from the folded inoperative position of Fig. 4 to the extended operative posi- -tion of Fig. l, the actuating line 55 is released, and the drop member and brace member 32 are allowed to swing downwardly. Usually, the weight of the truss structure is sufiicient to enable the component parts to assume the normal operative position shown in Fig. 1.

The line and pulley arrangement coacting with the particular hinge connection of the toggle brace 41 and of the drop portions 16 and 17 realizes a front-foldmg basketball backstop apparatus that may be quickly and easily raised from an extended operative position to a substantially horizontally folded, inoperative POSitlOIL Although the improvements have been described by making particularized reference to a single preferred embodiment, the detail of description is not to be understood as restrictive, numerous variants being possible within the principles disclosed and within the fair scope of the claims hereunto appended.
