COMBINATION LADDER AND OUTBOARD MOTOR CARRYING HAND CART Filed Nov. 30, 1955 INVENTOR. Aaez Z. flax/zany? 5?- BY O United States COMBINATION LADDER AND OUTBOARD MOTOR CARRYINGHAND CART Noel L. Dahlander, Sr., New Milford, Pa. Application November so, 1955, Serial No. 549,996 1 Claim. or. 280-4718) This invention relates to combination ladders and motor carrying hand carts, and more particularly to a sectional combination ladder and outboard motor carrying frame.

Among the objects of the present invention, it is aimed to provide a sectional combination ladder and outboard motor carrying hand cart which can be used as two independent ladders, one long and the other relatively short, to be secured to the gunwale or transom of a motorboat, and which ladders in turn can be assembled to form a handtruck or carrying frame for an outboard motor, the longer ladder section in truck assembled position having the motor attached to it, and the shorter ladder section provided with wheels to facilitate moving the motor when mounted on said truck-forming frame, and said shorter ladder also serving as a foot or support to enable the assembled truck-forming frame when sup porting a motor to stand erect or upright.

It is still another object of the present invention to provide a sectional combination ladder and outboard motor carrying hand cart consisting essentially of two ladders and handles for the ladders, which ladders and handles can be assembled to form a handtruck and carrying frame for an outboard motor, and which ladders can be independently equipped with handles and secured to the gunwale or transom of a motorboat and suspended over the side of a motorboat as swimming ladders.

These and other features, capabilities and advantages of the invention will appear from the subjoined detailed description of specific embodiments thereof illustrated in the accompanying drawings, in which- Fig. 1 is a perspective of the combination assembled into a handtruck or carrying frame for an outboard motor with an outboard motor shown in dotted lines.

Fig. 2 is an exploded view showing the two sections in independent ladder forming condition.

Fig. 3 is a longitudinal section of the longer ladder section secured to the gunwale of a motorboat and suspended from the side thereof.

Fig. 4 is an enlarged detail partly in section illustrating the connecting means for attaching the sections to one another and the handles .to the sections.

Fig. 5 is an enlarged detail similar to Fig. 4 showing another modification of the connecting means.

Fig. 6 is an enlarged detail similar to Fig. 4 showing still another modification where the upper handle and stile are integral with one another.

In the embodiment illustrated in Figs. 1 to 4, inclusive, there are shown two main ladder sections 1 and 2, and two pairs of crook-shaped handles 3 and 4, and 34 and 35. The main ladder section 1 as shown in Fig. 2 consists essentially of twostiles 7 and 8 and a plurality of rungs, the present embodiment being provided with twolower rungs 9 and 10 and a dual purpose upper rung 11 which also serves as the support for the outboard motor 12 shown in dotted lines in Fig. 1. Thestiles 7 and 8 andrungs 9 and 10 are preferably composed of metal 2,843,393 Patented July 15, 1958 stock, cylindrical or pipelike in form, while the rung 11 is preferably composed of wood.

Thestiles 7 and 8 are alike in shape, each having an upperhandle receiving portion 13 which extends substantially at right angles to the upperupright portion 14, which in turn extends substantially at an acute angle of about 45 to theintermediate portion 15, which in turn extends c an acute angle of about 45 to the lower upright portion 16, so that theportions 14 and 16 which extend away from one another relative to said intermediate portion and substantially in the same general direction as shown.

The upperhandle receiving portions 13 are preferably each provided with a plurality oforifices 17 to receive a spring-pressed button, such as the button. 18, see Fig. 4, secured to the bent fiat spring 19 mounted in the chambered portion of the inner end of a handle, such as thehandles 3 or 4.

The shorter ladder section 2 consists essentially of the U-shaped foot portion 20 which in the present instance is provided with two looped portions 21 .and 22 through which extends the rod orshaft 23 on the outer ends of which, extending outside of the looped portions 21 and 22, there are rotatably mounted the wheels 24 and 25, respectively. The looped portions 21 and 22 are connected to the short uprights 26 and 27 which extend upwardly from the limbs 28 and 29, respectively, of the U-shaped foot portion 20.

The upright portions 26 and 27 are preferably provided withapertures 36. The upright extensions 25 and 27 are of a diameter telescopically to receive the lower ends of the lowerupright portions 16 of the ladder section 1. The lower portions of theupright portions 16 are preferably each provided with a spring-pressed button, such as thebutton 18 of Fig. 4, secured to a fiat spring 19 mounted in theupright portion 16 and extending through anopening 31.

The outer ends of thehandles 3 and 4 are provided with rubber caps or buiiers 32 to engage the inner face of thegunwale 33 of a vessel, see Fig. 3, and thus protect the same from injury when the combination is used as a ladder.

The diameters of thestiles 7 and 8 are greater than the diameters of thehandles 3 and 4, respectively, in order telescopically to receive the same. In turn, the diameters of the upright extensions 26 and 27 are larger than the diameters of thestiles 7 and 8, respectively, in order telescopically to receive them. When the section 2 is used as a ladder, the extensions 26 and 27 are preferably provided with thehandles 34 and 35 similar to thehandles 3 and 4 to grip the gunwale of a vessel. The diameter of the tubular stock of thehandles 34 and 35 is similar to the diameter of the tubular stock of thestiles 7 and 8 so that thehandles 34 and 35 snugly fit in the tubular extensions 26 and 27 when telescopically received by the extensions 26 and 27 as shown in Fig. 2. Thehandles 34 and 35 are also each provided with an orifice therein similar to theorifice 31 of the upright 16 through which protrude spring pressed buttons, such as thebutton 18 secured to a looped flat spring 19 mounted in the tubular stock of the inner end portions of thehandles 34 and 35.

When the section 2 is used as a ladder, then thecross piece 36 alone serves as a rung, and thehandles 34 and 35 assume the position on the upper end of the gunwale such as assumed by thehandle 3 shown in Fig. 3. If, however, the section 1 is used as a ladder, then in addition to therungs 9 and 10 the wooden cross piece 11 will also serve as a rung at least to enable the swimmer to grasp the same when climbing up on the ladder formed by the section 1.

When the combination is to be stored away, the sec- 3 tions 1 and 2 are of course separated from one another, thehandles 3 and 4 removed from the section 1, and thehandles 34 and 35 removed from the section 2.

In turn, when the combination is to be used as an outboard motor carrying frame, then preferably as shown in Fig. 1, thehandles 3 and 4 will be secure-d in thehandle receiving extensions 13, thehandles 34 and 35 removed from the section 2, and the lower ends of theupright extensions 16 secured in the upright extensions 26 and 27 of the section 2 with the U-shaped foot portion eye tending in a direction opposite to the direction of thehandles 3 and 4, see Fig. 1. Thereupon the fastening clamp orhook 37 of the motor is secured to the wooden cross piece 11 as shown in Fig. 1. When so secured to the cross piece 11, the lower end of the motor 12 will be spaced from the foot portion 20. Due to the weight of the motor 12, it may be desirable to lay the section 1 on the ground when securing theclamp 37 to the cross piece 11. On the other hand, if properly supported, the combination frame when assembled as shown in Fig. 1 may be positioned upright resting on the foot portion 20. Preferably the wheels 24 and will be so mounted that the foot portion 20 will lie flat on the ground in the upright position of the combination frame in the interest of steadiness, either when attaching the motor 12 to the cross piece 11 or when removing the motor 12 from the cross piece 11, or when storing the motor so mounted on the combination frame in upright position. In turn, the wheels 24 and 25 will be so positioned relative to the U-shaped foot portion 20 that when tilted slightly backward, the combination frame can ride upon the wheels 24 and 25 without any hindrance from the foot portion 20. The foot portion 20 is long enough so that it may be engaged by the foot of the attendant either when mounting the engine 12 on the cross piece 11 or when removing the motor 12 from the cross piece 1.1, and the attendant thus by the weight of his body couuterbalances or pre vents tilting of the frame when he is manipulating the motor.

In the embodiment illustrated in Fig. 5, thebutton receiving openings 33 are mounted in thetubular stock 39 of the handle Miami the handle receiving portion at of the stile 42, similar to thestile 7 or 8 of the embodiment illustrated in Fig. l, is provided with thebent fiat spring 43 to which is secured thebutton 44 extending through an opening in thehandle receiving portion 41, in turn to snap into one of theopenings 38 of the handle 40. The plurality ofopenings 38 in the handle 40, the plurality ofopenings 17 in thehandle receiving portions 13, and the plurality of openings in the upright extensions 26 and 27 are provided to afford adjustment, either of the handles to accommodate a wider or narrower upper edge of agunwale 33, see Fig. 3, or in the case of the positioning of theupright portions 16 in the upright portions 26 and 27, to provide for a variation in the length of the section 1 relative to the foot portion 20.

In the embodiment illustrated in Fig. 6, the upper handle receiving portion 45 and handle 46 are integral with one another. In other words, one and the same tubular stock is formed not only into the stile 47 and upper handle receiving portion 45, but also into the handle 46.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claim.

It is, of course, also obvious that the embodiment illustrated in Fig. 6 is particularly desirable when the ladder is fabricated for a predetermined dimension of gunwale, that is, where adjustment is unnecessary. In the first place, when the handles at the upper ends of the stiles are integral with the stiles, there is of course no danger of the handles becoming accidentally dislodged from the stiles. In the next place, it makes it possible to have only four parts for the sectional ladder, to wit, (1) the section 1 with the upper handles integral therewith, (2) the section 2 with the wheels, and (3), (4) two handles, such as thehandles 34 and 35 illustrated in Fig. 2.
