RAYMOND E BHEND 171G. 2 BY A T'TOF?NE Y 3,072,376 BOAT SUPPORT AND HOLD-DOWN APPARATUS Raymond E. Bhend, 6605 Oliver Ave. S., Minneapolis 23, Minn. Filed Jan. 29, 1962, Ser. No. 169,397 2 Claims. (Cl. 248361) This invention relates to apparatus designed to enhance the utility of conventional small boat trailers; in particular, it concerns novel and improved means for securing a boat to such a trailer without sacrificing the inherent riding and other operational characteristics (generally of the two-wheeled variety) of the trailer.

It has been found that conventional small boat trailers adapted to carry light-weight outboard boats are generally deficient in at least two respects; they do not provide proper support for the under surface of all types of boat hulls, particularly regarding the lateral displacement of the hull during its over-the-road travels, and they are awkward to manage during the loading and unloading of the boat. The last mentioned shortcoming is due to the fact that the transom supports generally attached to the trailer are not universally adapted to fit over transoms of varying thicknesses and they do not take into account the difficulties frequently encountered in mounting the holddown brackets to the transom.

It is, therefore, a primary object of this invention to provide a boat support and hold-down apparatus that will overcome the shortcomings and disadvantages found in the eXisting prior art.

Another important object of this invention is to provide an improved boat support and hold-down device.

A further object of this invention is to provide a removable boat support and hold-down that can be attached easily to any conventional small boat trailer.

Yet another object of this invention is to provide in a small boat trailer attachment novel and improved means for guiding and mounting the hold-down elements forming part of the invention.

Another object of this invention is to provide a boat support and hold-down that is economical to manufacture, reliable in operation and extremely rugged.

These and other objects and advantages of the invention will become apparent from a consideration of the following detailed description and accompanying drawing wherein a preferred embodiment of the invention is shown by way of illustration only and not by way of limitation.

In the drawing:

FIGURE 1 is a perspective view of the invention as it is mounted upon the rear end of a trailer in engagement with the hull and transom of a boat;

FIGURE 2 is an enlarged fragmentary vertical elevational view, partially in section, illustrating some of the components of the invention;

FIGURE 3 is an enlarged view, partially in section, showing the details of construction of part of the invention;

FIGURE 4 is a fragmentary perspective view illustrating another feature of the invention; and

FIGURE 5 is an enlarged perspective view of one of the transom hooks forming part of the invention.

Looking now at the drawing, and more particularly to FIGURE 1 thereof, the invention, indicated in its entirety by the reference character A, is shown mounted in place upon the rear transverse member B of a conventional two-wheel trailer C. An outboard boat D having a transom E is carried by trailer C and supported and releasably held to trailer C by means of the invention A, as will be explained.

The structural elements of the invention include an elongated generally flat rigid base member 10, which cor- 3,072,376 Patented Jan. 8, 1963 ice responds in length and width to transverse member B, and is carried thereon in the manner shown in FIGURES 1 and 2. In many cases, transverse member B of trailer C is equipped with rollers 12 to facilitate the loading and unloading of boat D; base member 10 in such a case is placed in an overlying manner upon rollers 12 so that it is substantially in vertical register with member B. Further provided are a pair of outer hull supporting blocks 14, 16, which are secured to the upper surface of base member 19 adjacent the ends thereof. Outer hull supporting blocks 14, 16 are preferably thick enough to accommodate the contour of the hull near its chine but are not so thick as to lift the boat a great distance from the medial portion of base member. To support the boat in the middle, a pair of closely spaced inner

hull supporting blocks

18, 20 are attached to the upper surface of base member 10 on each side of the medial transverse axis thereof. This construction results in a space 22 coincident with the longitudinal axis of the boat into which is received the keelson 24 of the boat. Here again, the thickness of inner

hull supporting blocks

18, 20 is governed according to the average depth of the conventional keelson found in most boats of the type shown in the drawing.

The make-up of base member it) is completed by the addition of a pair of generally

hollow guide members

26, 28, each attached thereto adjacent outer hull supporting blocks 14, 16, respectively.

Guide members

26, 28 are formed of fiat stock resulting in a hollow cylindrical shank 30 (see FIGURE 3) having its axis vertically disposed immediately rearward of the rear ver tical edge of base member 10.

Cooperative with base member lit) and

guide members

26, 28 thereof, are a pair of removable hold-

down ties

32 and 34, which are adapted to secure the boat to the rear end of the trailer. Each hold-down tie 32, 34', consists of an elongated tension spring member 36 having a lower end 38 adapted to fit into a hook 40 suitably attached immediately below

guide members

26, 28 to frame member B of the trailer. Attached to the upper end of spring member 36 is an elongated chain or cable connector 42 which terminates in an upper eye 44. If chain material is used for connector 42, eye 44 may be dispensed with if desired. Removably attached to eye 44 of connector 42 (or in the case of a chain, the opening in each link thereof may be used) is a transom hook 46.

Transom hook 46 is adapted to fit over the upper or top edge of boat transom E, and for this purpose, as well as to facilitate ease in the use of the device, it is fashioned according to the configuration more particularly shown in FIGURE. 5 of the drawing. As shown therein, transom hook 46 is characterized by a lower horizontal leg 48 which its attachable to connector 42 either through eye 44- or through a link in chain 42. Connected to and integral with lower horizontal leg 48 is a first vertical leg 50 which is adapted to lie against the outer surface of transom E. Vertical leg 50 terminates at its upper end in an intermediate horizontal leg 52, the length of which is sufficient to allow it to overlie and engage the top surface of the transom. Connected to and integral with the inner end of intermediate horizontal leg 52 is a sec- 0nd vertical leg 54, which extends downwardly therefrom into engagement with the inner surface of the boat transoul in accordance with the loading imposed upon the provision of an upper horizontal leg 56 connected to and integral with leg 54 thereof. As shown in FIGURE 5, vertical leg 54 is shorter than vertical leg 50 to provide a greater contact of hook 46 with the outside of the transom in accordance with the loading imposed upon the assembly. The lengths of lower horizontal leg 48 and upper horizontal leg 56 are sufficient to allow them to be easily engaged by hand to facilitate the mounting and removal of hook 46 upon the transom.

In the use of the device, the trailer is loaded in the conventional manner, usually by running the boat thereon when trailer is in the water. The rear end of the boat is lifted up and base member 10 slipped between the rear end of the boat and the transverse frame member 12 of the trailer.

Tie downs

32, 34 are fastened at their lower ends into hooks 40 and drawn through guide members 26 and 23. Then hooks 4-6 are urged into position upon the transom against the spring pressure of spring member 32. The boat is thus securely attached to the trailer with little or no lateral displacement due to the supporting characteristics of inner

hull supporting blocks

18, 20 and outer hull supporting blocks 14, 16.

Guide members

26 and 28 prevent the unrestricted movement of

tie downs

32 and 34 during the movement of the trailer and also prevent damage to the finish of the transom. If desired,

hull supporting blocks

14, 16, 18 and 20 may be equipped with resilient contact surfaces (shown by reference character 60 in FIGURE 3).

My invention has been thoroughly tested and found to be entirely satisfactory for the use intended. It will be obvious to those skilled in the art that my invention may be modified by many substitution and equivalents and that this disclosure is intended to be illustrative only. Therefore, I intend to be limited solely by the scope of the appended claims.
