Description
Field of Invention
The present invention relates to boats and support system for supporting boats and particularly sailboats out of the water, and more particularly to a transverse cradle type support system that is particularly adapted and designed to accommodate and support boat hulls of various sizes and shapes.
Background of Invention
The review of the prior art and commercially available boat support systems will reveal that cradle type boat support systems are known and appreciated today. An appreciation of the state of the art in this area can be found from a review of the disclosures of the following United States Patents that relate to boat support systems in general: U.S. Pat. Nos. 3,131,902; 3,139,277; 3,554,394; 3,586,285; 4,094,527 and 4,155,667.
While boat support systems are commercially available today, they are not without their disadvantages. Principally among the disadvantages of commercially available boat support systems today is that they are generally limited in the type and size of boat that they will accommodate. Often boat support systems purchased today are only designed to support one size of boat. Furthermore the restriction goes on a step further inasmuch as the same will often only support a certain shape boat of that size. As a result boat manufacturers and dealers and other firms that utilize boat support systems in their business have found it frustrating in attempting to purchase boat support systems that are practical and to a significant extent universally compatible with a wide range of boat sizes and shapes.
In addition some commercially available boat support systems known today tend to be unduly complicated, and difficult to handle as well as being relatively expensive. Often one finds that because of a particular design approach that the size of individual components are required to be larger than necessary if the boat support system had been designed more appropriately. Obviously this adds weight and accordingly cost not to mention the added difficulties and effort required in handling and moving.
Therefore, there exists a real need for a boat support system, especially for sailboats, that is designed to easily and conveniently accommodate different size and shaped hulls and which is relatively simple and inexpensive. Further it is important that such a boat support system be designed such that it can assume a compact size and position for convenient and easy handling, storage and transport.
Summary of Invention
The present invention entails a transverse saddle type boat support system especially designed for sailboats, but which could be used for other types of boats as well, which overcomes the disadvantages and drawbacks of boat support systems of the prior art. In particular the present boat support system is designed to accommodate boats having hulls of various sizes and shapes. More particularly the boat support system of the present invention has a wide variety of uses. For example, the boat support system of the present invention can be utilized for supporting a boat during manufacturing or used for supporting the boat during shipping, or used to store a boat on, and finally can even be sold with the boat such that the owner will always have a dry storage system available.
In addition the boat support system of the present invention is designed such that the principal upstanding structure can be moved to a folded or transport position where the same lies closely adjacent the base frame structure of the boat support system. This essentially reduces the space occupied by the boat support system of the present invention to the area occupied by a generally flat rectangular base structure. Obviously this greatly facilitates the shipping and/or storage of quantities of the boat support system.
Briefly, from a structural point of view, the boat support system of the present invention includes a generally rectangular steel frame with a vertical support frame assembly mounted on each end. Each vertical support frame assembly includes a detachable hull support panel that generally extends transversely across the base frame structure. The hull support panels are provided with a selectively shaped and curved upper edge that is generally arcuate, which directly engages and supports the hull of the boat being supported. Because of the positions of the vertical support frame assemblies, this means that the boat is supported at fore-and-aft positions by the saddle type hull supports.
To stabilize the boat in a supported position, there is provided a keel restraining assembly that essentially comprises a pair of laterally spaced apart panels that define an opening therebetween for receiving the keel. The presence of the panels prevents the keel from moving laterally, thereby essentially stabilizing the boat in a supported position.
It is, therefore, an object of the present invention to provide a practical and reliable boat support system that will accommodate a wide range of hull shapes and sizes.
Another object of the present invention resides in the provision of a cradle type boat support system especially designed for sailboats which can be used for other types of boats as well, which utilizes a transverse type saddle support structure disposed at fore-and-aft locations underneath the hull of the boat being supported.
It is also an object of the present invention to provide a transverse saddle type boat support system of the character referred to above that is relatively simple in design, and which is particularly designed to minimize the size of respective components of the system, and which is relatively simple and inexpensive.
It is also an object of the present invention to provide a transverse saddle type boat support system of the character referred to above that is designed such that substantially all of the normal upstanding support structure can be easily and conveniently moved to a transport and/or storage position where the same lies adjacent the main or base frame structure of the support system so as to substantially reduce the effective height of the boat support system for transport.
A further object of the present invention is to provide a cradle type boat support system that is especially designed to be used by manufacturers, individuals or firms that ship and transport boats, and other firms and businesses which require the use of boat support systems in their everyday business.
Other objects and advantages of the present invention will become apparent from a study of the following description and the accompanying drawings which are merely illustrative of the present invention.

FIG. 2 is a front elevational view of the boat support system shown in FIG. 1.
Transverse Saddle Type Boat Support System
With further reference to the drawings, the transverse saddle type boat support system of the present invention is shown therein and indicated generally by the numeral 10.
Viewing boat support system 10 in detail, it is seen that the same includes a rectangular base frame structure, indicated generally by the numeral 12, that is preferably constructed of steel. Frame structure 12 includes a pair of laterally spaced longitudinal members 14 and 16. Welded or secured by other suitable means transversely between and generally underneath the rspective longitudinal members 14 and 16 are a series of transverse frame members 18, 19, 20, 21 and 22.
FIG. 1 illustrates the transverse saddle type boat support system 10 in an erect posture where the same is adapted to support a boat. As seen in FIG. 1, the boat support system of the present invention includes a vertical support frame assembly, indicated generally by the numeral 24, secured about each end of base frame structure 12. Viewing each vertical support frame assembly 24, it is seen that the same includes a pair of elongated side members 26 and 28 that are secured to the base frame structure 12. In particular, elongated side members 26 and 28 are pivotably mounted to end portions of the longitudinal members 14 and 16 by pivot pins or other suitable pivot connecting means. As will be discussed subsequently herein, this enables the entire vertical support frame assembly 24 to be folded down within or adjacent to the base frame structure 12.
Continuing to refer to the vertical support frame assembly 24, it is seen that the same further includes a horizontal reinforcing member 30 connected between the elongated side members 26 and 28. This gives rigidity to the vertical support frame assemblies 24.
Secured between the upper portions of the respective elongated side members 26 and 28 is a hull support panel 32 that is constructed of plywood or other suitable material. Hull support panel 32 is detachably mounted within elongated side members 26 and 28. There is provided a selectively shaped and curved upper edge 32a that is preferably padded with a carpet-like material. A resilient type material or some other suitable material to prevent damage, scratching or scarring the supported boat hull. It should be emphasized at this point that the upper supporting edge 32a can be particularly designed, shaped and curved to fit a particular size and shape of hull. It is appreciated that the boat support system 10 of the present invention could be provided with a variety of hull support panels 32 with each set being particularly shaped and contoured to fit a particular type and size of boat hull. This obviously gives the boat support system 10 of the present invention substantial utility inasmuch as it allows the same to accommodate and be compatible with a wide range of boat hull sizes and shapes. It is seen from viewing FIG. 1 that hull support panel 32 can be easily and quickly detached from the respective elongated side members 26 and 28 by simply disconnecting the bolts that serve to attach the hull support panel 32 to the elongated side members 26 and 28.
To reinforce the vertical support frame assemblies 24, each frame assembly is provided with a pair of diagonal braces 34 and 36. From the drawings, it is seen that the diagonal braces 34 and 36 extend from an upper portion of elongated side members 26 and 28 downwardly to where they connect to the longitudinal members 12 and 14 of the base frame structure 12.
To support the boat keel K, as illustrated in dotted lines in FIG. 2, there is provided a keel support board 38 that is supported by base frame structure 12 that generally lies or is positioned longitudinally across a series of transverse frame members 19, 20 and 21.
To prevent a supported boat, indicated by B in FIG. 2, from rotating within the saddle type cradle formed by the hull support panels 32, the boat support system 10 of the present invention is provided with keel restraining means, indicated generally by the numeral 40. With particular reference to FIG. 2, it is seen that the keel restraining means includes a pair of padded keel restraining panels 42 and 44. Restraining panels 42 and 44 are preferably disposed in spaced apart relationship so as to define an opening therebetween for receiving the boat keel K.
Restraining panels 42 and 44 are connected to a pair of support shafts 50 and 52 by universal couplers 46 and 48 that allow the panels 42 and 44 to pivot in order to appropriately conform to the outer surface of the boat keel K when a boat is supported by the system of the present invention. As seen in FIG. 2, the support shafts 50 and 52 are confined within a shaft support and holding structure 54 and 56 that extend up from the base frame structure. Each shaft support and holding device 54 and 56 is provided with a transverse opening therein for receiving the respective shafts 50 and 52. In addition, there is provided a set screw for appropriately securing the respective shafts 50 and 52 in a stabilized position where the respective restraining panels 42 and 44 lie on opposite sides of the boat keel K so as to restrain the same from moving laterally to one side.
In operation it is appreciated that a boat B can be disposed over the respective hull support panels 32. It is appreciated that in this posture the boat B is supported fore-and-aftly above the base frame structure 12. In addition the keel restraining means 40 prevents the keel K from moving side to side.
It is further appreciated that the hull support panels 32 can be quickly and easily removed and replaced by other hull support panels that will appropriately fit a boat to be supported. This gives the boat support system 10 of the present invention a great deal of utility inasmuch as the same can support boat hulls of various sizes and shapes.
Finally, to easily and conveniently transport and/or store the boat support system 10 of the present invention, it is appreciated that the diagonal braces 34 and 36 can be removed and the entire vertical support frame assembly 24 pivoted downwardly and inwardly onto the base frame structure 12. This obviously reduces the height of the support system 10 and enables a quantity of such systems to be stacked one over the other for transport and/or storage.
The present invention, of course, may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended Claims are intended to be embraced therein.
