1 Claim. (Cl. 280-4713) This invention relates generally to devices for use with outboard motors, and more particularly to an outboard motor stand and hand truck or dolly.

With the current increase in interest in speed on the water, outboard motors are becoming much larger than ever before, because of the greater desire for more horse'- power. Because of this, the handling of these heavier larger motors is a very diificult task. Accordingly, the primary object of this invention is to provide a device which may be used to transfer an outboard motor between its mounted or operating position on a boat to a place of storage, and this may be done by one man as a comparatively easy task.

Another object of this invention is to provide a device of the character described which may be used as a stand which will hold the motor in an upright position during storage. v

Still a further object of this invention is to provide a device of the character described which is a safe, steady, platform for storage in a horizontal position during transportation of the outboard motor by a vehicle or the like.

Yet a further object of this invention is to provide a device which will firmly hold an outboard thereto, yet permit pivotal movement of the motor clamp, so that the device may place the motor onto the transom of a boat with the motor clamp being clamped to the transom, and the outboard motor may thus be attached to and removed from a boat without the necessity for a person to carry the device, since a stand and dolly may be used for that purpose.

Yet a further object of this invention is to provide a simple and inexpensive device yet one which is exceeda ingly eifective for the purpose for which it is designed.

The foregoing objects and others ancillary thereto are accomplished as follows:

According to a preferred embodiment of my invention, two frame sections are provided which are pivoted together, and may be locked in preselected angular positions with respect to each other. The main frame section has wheels at the bottom end thereof for easy transportation, and the upper end thereof has two inwardly projecting pins spaced from each other. An adapter is provided which may be fastened to the motor clamp of an outboard motor and left permanently aflixed thereto. This adapter has inner tabs afiixed thereto with aligned openings therethrough so a bolt may be passed through the openings through the motor clamp of an outboard motor and thus fix the adapter to the motor clamp. Aligned concentrically with these openings and formed in the sides of the adapter are larger openings into which the previously mentioned pins may be placed so that the adapter is pivotally mounted with respect to the pins. The pins have circumferential grooves formed therein and spring biased levers are urged towards the grooves so that when the pins are locked in position by the lever, pivotal rotation thereof will be permitted. A resilient flexible strap is provided on the lower end of the first Patented Dec. 8, 1959 frame section for holding the motors shaft housing in place.

The novel features that are considered characteristic of the invention are set forth with particularity in the appended claims. The invention, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawings, in which:

Figure 1 is a side elevational view of the device comprising the present invention with an outboard motor afiixed thereto illustrating the device in use as a stand;

Figure 2 is a front elevational view of the device with a second position thereof being illustrated in phantom lines;

Figure 3 is a side elevational view of the motor aflixed to the device illustrating its use in positioning a motor onto the transom of a boat;

Figure 4 is a vertical sectional view taken substantially along the plane defined by reference line 44 of Figure 1 illustrating details of construction of the adapter;

Figure 5 is a vertical sectional view taken substantially along the plane defined by reference line 55 of Figure 4 illustrating further details of construction thereof;

Figure 6 is a perspective view of the adapter to be used in conjunction with the present invention; and

Figure 7 is a bottom elevational view of the motor clamp and a second type of adapter for securing the same to the stand.

Referring now more particularly to the drawings, the numeral 10 generally designatesthe first frame section which is the main part of the present invention. A second frame section 12 is pivotally connected thereto near the upper end thereof. An adapter 14 is to be connected to the upper end of the first frame section and will hold the outboard motor clamp thereto.

The first frame section 10, is constructed of two upwardly converging rods 16, which are bent so as to form vertical portions 18 at their lower ends. An axle 20 is rotatably joumaled through the lower ends of the vertical portions 18 of rod 16, and wheels 22 are connected at the outer ends thereof so that the device is made more mobile. A horizontal support rod 24 is connected between the medial portions of rods 16 to add further rigidity thereto. Integral with the upper ends of rods 16 are vertical rods 26 which are parallel to each other and disposed inwardly with respect to the vertical portions 18. The rods 26 are provided with lateral, spaced apart, opposite parallel arms 27 which are bent inwardly to form axially aligned projecting terminal pins 28. It is to be noted, however, that the pins 28 are not in direct alignment with the rods 26 but are olfset therefrom by means of arms 27 which are interposed between the pins 28 and the upper ends of rods 26, as is shown more clearly in Figure 1.

The second frame section 12 is constructed of a hori- "zontal rod 30 which has upwardly projecting vertical rods 32 connected to the outer ends thereof. Inwardly converging members 34 are connected to the upper end of rods 32, and their free ends are affixed to parallel and vertical members 36 which are disposed inwardly of members 32, and are arranged so as to overlie the vertical members 26 of first frame section 10. It is to be noted that a pivotal connection 38 is made between the upper ends of rods 36 and the medial portion of vertical rods 26. Looking now more particularly at Figures 1 and 2, it may be seen that the members 32 and 36 are formed at an angle to each other so that the lower bar 30 provides a supporting stand or leg for the device when it is to support a motor as illustrated in Figure 1. In this position, bolts 40 are passed through the lower ends of rods 36 and into openings formed in the lower ends of rods 26 so that the sections may be locked together. However, the bolts 49 may be removed from the lower openings in rods 26 and the second frame section pivoted so that the bolts 49 can be inserted into upper openings in vertical rods 26 whereby the device will be opened to a position illustrated in Figure 3 and locked in that position. It may thus be seen that the device may be pivoted into two positions and locked in each of the positions.

A flexible strap 42 has a hook 44 on one end thereof with which it is attached to horizontal support 24. The other end thereof has a spring 46 affixed on the end thereof which in turn has a hook for attaching it to axle 20. However, as may be seen more clearly in Figure l the strap 42 may be used to hold the motors shaft housing fixedly to the first frame section.

The adapter 14 is constructed of a bottom plate 50 and upwardly projecting side plates 52. The forward portion of the side plates have inwardly extending Walls 54 affixed thereto to which rearwardly projecting tabs 56 are connected. These tabs are only attached along one vertical wall to walls 54. A pair of aligned openings 58 are formed through the tabs 56. Another pair of aligned openings concentric with openings 58 are formed in side walls 52 and these are designated by numeral 60. A lever 62 is pivoted at 64 adjacent each opening 60 and on the inner surface of wall 52, so that the lever 62 may partially cover the opening 60. The upper end thereof is formed with a handle 66, and the lever 62 is biased as by spring 68 which is connected at 79 to the inner wall and at the other end to the upper portion of lever 62.

In use, the conventional type of outboard motor 72 having a shaft housing 74 and a motor clamp 76 is to be mounted to the device comprising the present invention. The adapter 14 would be connected to motor clamp by a bolt 73 which projects through the openings 58 and locked thereto by a nut 89 thereon, said bolt 7 8 being the usual one pivotally connecting the motor 72 to the motor supporting clamp 76, as shown in full and broken lines in Figure 4. The adapter thus becomes part of the motor clamp 76 and motor 72. Then, the levers 62 are engaged in circumferential notches 82 on the pins 28, and the device may then be moved into the position illustrated in Figure 3 whereby it may be used for transportation purposes or as in Figure 1 where it may be used as a stand.

As will be seen, the adapter 14 extends under and supports the clamp 76 and hence the motor 72 on the frame to take the Weight of the clamp 76 and motor 72 ofi the pivot bolt 78 when the motor 72 is being transported.

A second embodiment of the adapter is illustrated in Figure 7 wherein the horizontal rods 127 are flattened as at 90 on their outer ends thereof and an opening 92 formed horizontally therethrough. Special type of wing nuts 94 are then rotatably engaged within the openings 92. These wing nuts 94 are constructed having the conventional type of wing nut construction 96, wherein an inner circumferential groove 98 is provided and a circular flange 100 disposed outwardly from the groove, whereby the outer peripheral edge of openings 92 may be engaged within groove 98, so that the wing nut 94 may be rotatable therein. Of course, the wing nut is threaded as at 102 as is conventional with wing nuts. The flange 100 may be formed on the wing nut 94 by upsetting the appropriate end of the wing nut after its insertion through the related opening 92. Then, instead of bolt 73 as was used in the previous embodiment, a longer bolt 104 is used which is threaded as at 106 at either end thereof. This bolt is disposed through motor clamp 76, and conventional nuts 108 locked to either side thereof whereby the motor clamp 76 will be centrally positioned therebetween. The threadedends 106 of the openings 92, are threadedly engaged within internally threaded wing nuts 94. Then, by tightening up on wing nuts 94 the motor clamp is then locked to the stand. The use of this embodiment of the invention may then be used in conjunction with a motor as was previously described with the first embodiment.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A handling device for an outboard motor having a clamp and a pivot connecting said motor and clamp together for relative swinging, said device comprising a first frame section having supporting wheels thereon, a second frame section for propping the first frame section in upright position on said wheels for transporting an outboard motor, means pivoting said second frame section on said first frame section for swinging thereon into and from propping position, means pivotally connecting said first frame section to said clamp for swinging about the axis of the pivot connecting said motor and clamp, and means on said frame sections for locking said frame sections to each other when the second frame section is swung into and from propping position, said means pivotally connecting the first frame section to the clamp comprising an adapter pivoted to said clamp coaxially with the pivot connecting said motor and clamp and underlying and supporting said clamp to support the motor on said first frame section to take the weight of the clamp and motor off the pivot of the clamp to the motor when the motor is being transported.
