hUnited States Patent DIVING BOARD George D. Dunklee, Dorice M. Dunklee, and Donovan M. Dunklee, Doster, Mich., assignors to Allegati Products Company, Allegan, Mich., a corporation of Michigan Application October 11, 1956, Serial No. 615,258
11 Claims. (Cl. 272-66) This invention relates to a portable diving board.
The main objects of this invention are:
First, to provide a portable collapsible diving board which is very stable when erected and does not require anchoring to a dock or other supporting surface.
Second, to provide a collapsible diving board which may be very compactly collapsed and at the same time quite quickly erected for use.
Third, to provide a portable diving board which is relaitvely light in weight and at the same time is strong and durable and stable when erected.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is dened and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
Fig. l is a side elevational view of a diving board embodying our invention, disposed upon a supporting surface conventionally illustrated.
Fig. 2 is a fragmentary plan View.
Fig. 3 is a rear elevational view.
Fig. 4 is a fragmentary view partially in vertical section on a line corresponding to line 4 4 of Fig. 2.
In the accompanying drawing we have illustrated our invention as embodied in a collapsible structure. It is desired, however, to point out that our invention is capable of embodimnet in a noncollapsible structure.
The embodiment of our invention illustrated comprises a rear leg unit including legs 1--1 connected at their upper ends by the top bar 2, the legs and top bar in the embodiment illustrated .being formed of a piece of tubular stock. The legs are connected adjacent their lower ends by the cross bar 3.
The laterally spaced forwardly and downwardly inclined longitudinal `bars 4 are attened and curved at their rear ends 5 to rest upon the top piece 2 of the rear legs and are detachably secured thereto by the bolts 6 provided with winged nuts 7 to facilitate rapid assembly and disassembly. The bars 5 have downturned front leg portions 8 at their front ends, these being relatively short as compared to the rear legs 1.
The side bars 9 are pivotally connected to the outer sides of the legs S at 1i) and are detachably secured to the rear legs 1 by means of the bolts 11 provided with winged nuts 12, the bars 9 being arranged on the inner sides of the rear legs.
The braces 13 are pivotally connected to the longitudinal bars 4 at 14 and detachably secured to the rear legs by the bolts 11, the braces being arranged on the inner sides of the side bars 9. T'hus arranged, the rear legs and the longitudinal bars are connected to provide a rigid frame and, at the same time, one that can be readily knocked down.
The longitudinal bars are provided with laterally spaced fro-nt, rear and intermediate cross bars 15, 16 and 17, respectively.
The upwardly facing cupped holders 21 are lxedly mounted in laterally spaced relation on the intermediate cross bar 17, desirably by welding, as indicated at 22, see Fig. 4.
The downwardly facing cupped sockets 25 are disposed within the bed members 18 in opposed relation to the holders 21 to receive the upper ends of the springs. These spring sockets 25 are connected to the bed members by means of the studs 26. The auxiliary or pickup springs 2t) are of less diameter and height than the main springs and are supported at their lower ends by the upwardly projecting studs 27 disposed centrally of the spring holders 21 and secured thereto by the welds 28.
The springboard 29, which is preferably provided with an antislip facing 30, is connected to the top piece 2 of the rear legs by means of the yoke 31 which embraces the rear end of the springboard, the arms being pivoted on the top piece 2. The springboard is fiXedly secured to this yoke as by means of screws 32.
The springboard is provided with a cross piece 33 disposed in substantially spaced relation to the rear end of the springboard in supported engagement with the bed members 18. To hold the springboard in this supported engagement, We provide a tension spring 34 which is connected at 35' to the springboard adjacent its front end, its lower end being connected to the front cross bar 15 by means of the eye bolt 36. This rebound spring 34 is tensioned so as to hold the springboard thrust member 33 upon the bed members at all times; that is, while the diving board is being carried about and also when the springboard is released as the result of being relieved of the load of a person diving therefrom or the like.
The legs are desirably provided with elastic or other antiskid foot portions 37.
With this arrangement of parts, while the complete diving board is relatively light in weight and may be carried about in assembled or set up form, the parts are so arranged so that it is very stable and it is not necessary to anchor it to a deck or other surface.
The load upon the diving board is in general central relative to the rear and front legs. The diving board does not project substantially beyond the front legs.
The structure may be readily collapsed and set up and at the same time the parts are securely connected by a manipulation of four bolts; that is, the two `bolts 6 and the two bolts 11.
The springs are effectively retained when the structure is set up, but may be removed for compactness in packagmg.
The rebound spring is provided with a hook 38 at its lower end which may be disengaged from the eye bolt 36.
The springboard yoke 31 is disposed between the longitudinal bars 4, and its lateral movement is limited by the stops 39, see Fig. 4.
We have illustrated and described our invention in a highly practical embodiment thereof. We have not attempted to illustrate other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt our invention as may be desired.
Having thus described the invention, what is claimed as new and is desired to be secured by Letters Patent is:
