Balthazar, Moline, 11]., assignor to Buddy L Corporation, Moline, Ill. Filed May 27, 1968, Ser. No. 732,240 Int. Cl. A63h 33/30, 11/10 U.S. C]. 46-40 12 Claims ABSTRACT OF THE DISCLOSURE A toy vehicle representively embodying a wrecker truck having dual cranes or derrick arms and dual Winches, one winch for each crane, and control means for operating the winches in unison or independently of each other.

BACKGROUND OF THE INVENTION Toy vehicles in the form of Wreckers and the like are of course well known and these to a large extent are patterned after actual-size vehicles, with considerable ingeniousness devoted to duplication of structure and function within the limitations imposed by the small scales on which the toys are constructed. One of the principal problems to be solved is that of duplicating the function of a full-size complicated mechanism, especially where the full-size vehicle utilizes actual motive power, such as power take-offs, hydraulic lifts etc., because such components cannot be faithfully reproduced in a toy except at great expense. The toy designer therefore resorts to manually operated mechanisms and attempts to make these as representative as possible of their actual-size counterparts.

SUMMARY OF THE INVENTION According to the present invention, a basic vehicle, such as a toy wrecker, is modified by the provision of a dual winch and crane system wherein there are two cranes or derrick arms mounted for independent lateral shifting and two winches, one for each crane or arm and having a simulated cable and hook system for hoisting, pulling etc. The winches are compactly arranged in association with an input shaft and gear means is provided among the shaft and winches, including shiftable gears whereby the two winches, and thus their cables, may be operated simultaneously or independently of each other. A selector is provided for selecting the condition of the gears and this selector forms part of at least a simulated warning or hazard lamp, such as is conventionally found on wrecker and other highway, wrecker, police etc. vehicles.

DESCRIPTION or A PREFERRED FORM or THE INVENTION The vehicle serves as a base means and as such comprises a fore-and-aft chassis 10 carried on front and rear wheels 12 and 14 and including a cab 16 and a rear body or box 18 having a flat bed or floor 20. All this structure may be conventionally formed of pressed steel or plastic or a combination of the two and, as seen, the toy is substantially a scale model of a fullsize truck.

Just behind the cab, the floor 20 has rigidly secured thereto in any suitable manner a box-like support designated in its entirety at 22. A typical mounting of the support on the floor may be achieved by slotting the floor at several locations and inserting support-carried tabs through the slots and bending the tabs over as suggested at 24. The support is preferably of pressed steel to provide adequate strength. This support has opposite upright side walls 26 and an integral top wall 28, and its rear wall is preformed with generally rectangular openings whose marginal edges provide integral bent-in or bent-out ears, two of which are lower ears 30 spaced laterally apart and cooperative with an integral lower transverse flange 34 to carry a pair of upright pivot pins 36. A pair of similarly laterally spaced apart upper ears 38 carry pivots 40 respectively coaxial with the pins 36. The lower pivots 36 respectively carry the lower ends of upwardly and rearwardly inclining crane or derrick arms 42 and 44 and the upper pivots provide forward connections for rearwardly extending braces 46 and 48 Which have their rear ends hooked into the arms 42 and 44 and the upper pivots provide forward connections for rearwardly extending braces 46 and 48 which have their rear ends hooked into the arms 42 and 44, respectively, the whole providing a derrick means in which the arms 42 and 44 may be freely swung laterally, within limits, to extend straight rearwardly or laterally to the respective side of the vehicle body (FIG. 2). In a simulated operation, one arm may be swung to one side for connection to a wrecked vehicle off the road and the other arm may be swung to the opposite side to secure a purchase on a tree or other fixed object at the opposite side of the road by means of cables or flexible elements to be described subsequently.

The side walls 26 of the support 22 are coaxially apertured on a transverse axis to joumal a drive shaft 50 having at its left-hand end a wheel 52 provided with a handle 54, this shaft preferably being formed of an adequately heavy section of wire in which the wheel and handle are formed integrally. This shaft has a drive gear 56 fixed thereto intermediate the support walls 26.

Part of the apertured rear wall structure of the support 22 includes forwardly bent cars 58 and 60, laterally spaced apart and parallel to the walls 22 for coaxially journalling rightand left- hand winches 62 and 64 on which are wound flexible elements or simulated cables 66 and 68, which cables are guided through apertures 70 in the support top wall 28 and extend over sheaves or guides 72 and 74 respectively at the upper rear ends of the crane arms 42 and 44. Each cable is fitted with a weighted hook 76 (FIG. 1). Each winch is in the form of a shaft, the right-hand winch 62 being journalled in the right-hand apertured ear 58 and the adjacent side wall 26 and the left-hand winch 64 being coaxially journalled in the left-hand apertured car 60 and its companion side wall 22 (FIG. 3). The winches respectively have affixed thereto gears 78 and 80 adapted to be engaged with or disengaged from the drive gear 56 (FIGS. 3, and 6). All three gears may be of any suitable material, such as molded plastic having good wear qualities. The winch 62, as well as its winch gear 78, is biased axially inwardly so as to mesh its gear with the input or drive gear 56, a coiled compression spring 82 being found suitable for this purpose and acting between the gear 78 and the proximate ear 58 (FIGS. 3, 5 and 6). A similar spring 84 performs the same function for the winch 64.

Since the springs 82 and 84 normally bias the winches axially inwardly or toward each other, both winch gears 78 and 80 will normally mesh with the gear 56 on the drive shaft 50 and therefore both cables 66 and 68 will be wound and unwound in unison. However, it is desirable that either winch be operative independently of each other and, accordingly, the gear means 56, 78, 80 is designed for shifting among three conditions, the accomplishment of which rests in part on the above-described nature of the winch shafts as being axially slidably carried as well as being journalled in their respective supporting means ( ears 58 and 60 and support side Walls 26); i.e., each winch is shiftable laterally outwardly against the bias of its spring 82 or 84. The shiftability is such that the shifted winch or driven gear disengages from the driving gear 56, as best seen in FIG. 6.

The shiftable gear means 56, 78, 80 is under the control of tri-positionable means 86, here including a vertical shaft element 88 journalled in the support top wall 28 and in another bent-in ear 90 formed from the rear wall structure of the support 22. As best seen in FIGS. 3, 5 and 6, the inwardly biased gears 78 and 80 are limited to positions in which they are spaced axially apart to accommodate a cranked or yoke portion 92 in the shaft element 88, here again resort being had to forming the means 86 from an adequately heavy section of steel wire. 7

The means for turning the element 88 is here a knob 94 fixed to the upper end of the shaft element exteriorly of the support top wall 28, which knob here is dome shaped and takes the form of a simulated hazard or warning lamp, preferably colored red or typically yellow etc. as is conventional on full-size vehicles of this type. It follows, of course, that an actual battery powered lamp etc. could be used except for the increase in cost. To shift gears, the user simply turns the knob 94 from a central neutral position, in which both winch gears 78 and 80 are in mesh with the driving gear 56, to either side by 90, disengaging one or the other of the winch gears from the gear 56 so that the selected in-mesh gear will reel its cable 66 or 68 in or out. FIG. 6 shows the winch gear 80 disengaged from the input gear 56 because the means 86 has been turned 90 clockwise as seen from above. The knob 94 may have a pointer 96 thereon and the top support wall 28 may have indicators 98 and 100 to show the position of the knob (FIG. 2). As best shown in FIG. 3, the outer ends of the shafts on which the winches 62 and 64 are based may be headed to provide stops for limiting inward movement of the winches to an extent providing for the axially spaced apart relationship that accommodates the element yoke or crank 92.
