FRANK .ALIBACH, or ST. LOUIS, MISSOURI, ASSIGNOR TQFRED MEDAB'JJUMANUFAC-P TUBING COMPANY, or sr. LOUIS, rarssounr, aconronar oiv' -or. Mrssou tr STRADDLE STAND R SUPPORT Application filed August 10, 1928,. Serial No. 298,795.
This invention relates to that class of straddle stands or supports adapted to afiord overhead support for playground exercising appliances, such as swings, horizontal bars, etc.,
and has for its object.
To provide a structural combination and arrangement of upright side rails horizontal tie rails, horizontal stringer or rail and vertical bracing rails in a stand or support of m the type above referred to, by means of which a light strong and rigid structure, capable of ready removal from place to place is provided.
To provide a ready and eifective construction and combination of parts in the described type of stands or supports whereby a horizontal bar for athletic exercise is adjustably supported at the desired distance above the ground or floor, all as will hereinafter 20.111011, fully appear.
In the accompanying drawing:
Fig. 1, is a perspective view of a stand or support embodying this invention.
Fig. 2, is a detail front elevation illustratzs ing the bracing arrangement between the top horizontal stringer and the supporting side upright members of the structure.
Fig. 8, is a fragmentary side elevation of the separable connection between the horizontal exercising bar and a vertical rail of the structure.
Fig. 4, is a detail front elevation of the same.
Like reference numerals indicate like parts I in the different views.
In this invention the general arrangement of parts of the stand or support is that of the ordinary straddle type and in which a pair of side supports 1 of an A-form carry at thelr upper ends a horizontally arranged transverse stringer or rail 2 from which are suspended a swing 3, a trapeze 4 and other like appliances as used in playground exercises.
Such appliances have detachable attachment to the stringer or rail 2, so as to be capable of removal and replacement one for the other as required in the use of any particular appliance, and as usual in this type of playround apparatus. In the structure shown 50-1n Fig. 1, each of the side supports 1 comprisesia pair of-rails oruprights which meet in adjacentrelation at top and are-attached to the respective. faces of the aforesaid stringen on rail 2, by bolts or like fastening means passingwthrough the respective parts,-
7 and in .a mannerwhich will cause a convergenceofthe supports 2 towardseach otherat top, while. their; lower and spread apart ends. of said supports are connected together in a spread apartrelation by front.- and rear. rails bottomirails. orbraces 5, witha firinconmotion between the parts. effected by :serew boltsor like. fastening meansisupplemented by diagonal bracing rails 6 secured in angular.
relation to therespective railsof the supports 1 and frontand. rear rails or-braces 5, as shown: in Fig. 1.
At thehmidheight; of each upright support-'- 1 a horizontal tie rail 7 is .fixedly secured by" screwbolts :orlike fastening .meansto secure the pair ofrailscom-prising each supportl in proper spread; apartl relation. In this construction each of. the tie rails? also-provides abutments. for the lower ends of'the hereinafter; described pair of. vertically arranged bars orrailsSby means of-iwhich.a'horizontal exercising .bar 9 is supported at itsendsin ;-a-
Withsuclrformation and arrangement Ofn the parts a substantial ztrussing iofstherespeca tive xupper corners of the stand iorsupport is attained and which is adaptedi to withstand 2 the. usual heavy stressesthat are imposed in actual use.
In. the. above described construction the a vertical bars-8 have a-spaced relation of-anextent equal to the'width of the structure and that of the :main central portion of; the-round horizontal: exercising bar 9 heretofore referred to; and said-vertical bars 8 are formed with counterpart series of socket orifices in vertically spaced relation, with the upper portion of each of said socket orifices of a circular formation of a size corresponding with the diameter of the horizontal bar 9 in order that said horizontal bar may be passed therethrough in an endwise manner, while the lower portion 10 of each of said socket orifices have a reduced width and are adapted to receive a correspondingly reduced end 9 of the horizontal bar 9 to hold the same from both turning and endwise movements in actual use.
I claim as my invention:
1. A stand for exercising appliances of the type described, comprising a horizontal top stringer, a pair of side supports in sloping relation and secured at the upper end to the top stringer at a distance from the ends thereof, the lower ends of the supports having a greater spread relation than the length of the top stringer, tie rails secured to said supports near their mid-height, and a pair of vertical bars secured at their upper ends to the respective outer ends of the aforesaid top stringer and at their lower ends to the tie rails aforesaid, said vertical bars having a spaced parallel relation adapting them to provide vertically adjustable means of attachment for exercising and like appliances.
2. A stand of the straddle type, comprising a horizontal top stringer aifording means for attachment for swinging exercising appliances, a pair of side supports converging together at top, each support comprising a pair of rails which incline towards each other at top and secured at their upper ends to the aforesaid horizontal stringer, a tie rail secured to said pair of rails at their midheight, the top stringer having end extensions beyond the points of attachment of the side supports, and vertical bars attached to said end extensions of said stringer and said tie rails to provide strengthening trusses for the upper corners of the stand, each vertical bar aforesaid having a vertical series of socket orifices for receiving and supporting the ends of a horizontal exercising bar.
3. A stand of the straddle type, comprising a horizontal top stringer affording means for attachment for swinging exercising appliances, a pair of side supports converging together attop, each support comprising a pair of rails which incline towards each other at top and secured at their upper ends to the aforesaid horizontal stringer, a tie rail secured to said pair of rails at their midheight, the top stringer having end extensions beyond the points of attachment of the side supports, and vertical bars attached to said end extensions of said stringer and said tie rails, to provide strengthening trusses for the upper corners of the stand, each vertical bar aforesaid having a vertical series of socket orifices for receiving and supsignature.
