Description
- 1. Field of the Invention
- The present invention relates generally to water sports such as wakeboarding. More particularly, the invention concerns a wake tower of novel construction for use with powerboats for towing a performer behind the boat using a towrope that is connected to the wake tower.
- In recent years the sport of wakeboarding has become very popular. As the name implies, the wake boarder intentionally rides the wake of the boat and prefers to have as large wake as possible generated behind the boat. Experience has shown that to take full advantage of the wake generated by the boat, it is preferable to anchor the towline used to tow the wake boarder at a relatively high elevation above the deck of the boat. Accordingly, a large number of elevated wake towers of various constructions have been suggested in the past.
- Typically, the prior art wake towers comprise a rather large and somewhat elaborate framework that is affixed to the boat deck. Such prior art wake towers are heavy and generally quite cumbersome to install and remove from the boat. Further, such towers may interfere with the boat's passage beneath bridges and other types of overpasses. Additionally, because of the complexity of the frame-work of several of the prior art wake towers, visibility of the operator of the boat can be impaired. Exemplary of somewhat typical types of prior art wake towers are those illustrated and described in U.S. Pat. No. 5,979,350 issued to Larson et al. and U.S. Pat. No. 6,193,819 issued to Larson et al.
- To accommodate the overhead clearance problem exhibited by certain of the prior art wake towers, some prior art wake tower structures can be dismantled if necessary. However, such prior art structures often have questionable structural stability when erected and can present substantial safety hazards after being disassembled. For example, after the wake tower structures have been disassembled they can present a substantial tripping hazard to passengers on the boat especially when the boat is being rocked by waves. Further, in their dismantled configuration, the wake tower structures typically undesirably reduce the usable space on the boat deck.
- Another approach to accommodating overhead clearance problems has been to construct a wake tower assembly that is pivotally interconnected with the gun-wales of the boat so that the wake tower can be moved from an elevated position to a lowered position. Exemplary of this prior art approach, it is a wake tower assembly sold by the Titan Company of Rancho Cordova, Calif.
- By way of summary, one form of the wake tower assembly of the present invention comprises a first base member that can be connected to the gunwale on one side of a power boat; a second base member that can be connected to the gun-wale on the opposite side to of a power boat; a generally U-shaped, structural member having a first curved side connected to the first base member and a second curved side connected to the second base member, each of the sides having an upper portion and a lower portion each of which is generally oval in cross-section, the lower portion of each of the sides having a first width and the upper portion of each of the sides having a second width less than the first width; and a bight portion interconnecting the upper portions of the sides, the bight portion being either generally circular or generally oval in cross-section.

- Referring to the drawings and particularly to FIGS. 1, 4 and5, one form of the wake tower of the invention is shown interconnected with a
powerboat 30 of conventional construction having abow portion 30 a and astern portion 30 b. As best seen in FIG. 5, the powerboat also has first and second transversely spaced apart gunwales 32 and 34 respectively to which the wake tower is connected. In the present form of the invention the wake tower includes an upwardly extendingfirst base member 36 connected to thefirst gunwale 32 and an upwardly extendingsecond base member 38 connected to saidsecond gunwale 34. Thebase members - Interconnected with the base members is a generally U-shaped, upwardly extending structural assembly generally designated by the numeral40. The
structural assembly 40 includes a generally “L” shapedstructural member 42 having a firstcurved side 42 a and a cast aluminum,first connector segment 44. Structural member 40 a is connected to aluminumfirst connector segment 44 by any suitable means such as welding. In a manner presently to be described,connector segment 44 is, in turn, pivotally connected tofirst base member 36.Structural assembly 40 also includes a second generally “L” shapedstructural member 46 having acurved side 46 a and a second, castaluminum connector segment 48 that is connected to secondcurved side 46 a by any suitable means such as welding.Connector segment 48 is, in turn, pivotally connectedsecond base member 38. - As will be discussed in greater detail hereinafter, each of the sides of
structural assembly 40 is first swaged into the desired configuration and then is strategically formed to create a gracefully curved, tapered portion having an oval shape. More particularly, as best seen in FIGS. 1 and 4, each of the sides of thestructural assembly 40 includes alower portion 51 having a first width W and anupper portion 53 having a second width W-1 that is substantially less than said first width W.structural assembly 40 further includes abight portion 54 interconnectingupper portions 53 of the sides. As indicated in FIG. 4,bight portion 54 is generally circular in cross-section. However, it is to be understood that, for certain applications,bight 54 can be oval in cross-section. - In the form of the invention shown in FIGS. 1 through 11, the wake tower further includes a tow
rope connector member 56 that is connected to and spansupper portion 53 of thesides connector member 56 is a conventional type ofconnector 58 to which the towrope “TR” can be connected. - Turning next to FIGS. 6, 7 and8, a portion of one side of the wake tower of the invention is there shown. It is to be understood that the other side of the wake tower is of a similar construction, but is not shown in the drawings in order to simplify the specification. Each of the base members is provided with a
cavity 60 and each of the connector segments is provided with a pair of spaced apart, downwardly extendingears ear 62 has a bore 62 a formed therein. Similarly, downwardly extendingear 64 has a bore 64 a formed therein. Receivable within bore 62 a is apivot pin 66 about whichside 46 andconnector segment 48 can pivot in the manner shown in FIG. 11. - As illustrated in FIGS. 9 and 10,
pivot pin 66 extends through aligned bores 69 formed inbase member 38. Similarly, a lockingpin 72 is receivable within bore 64 a formed inear 64.Pivot pin 66 extends through aligned bores 73 formed inbase member 38 and, when in position within these openings in the manner shown in FIGS. 6 in 9, prevents pivotal movement ofside 46 andconnector segment 48 aboutpivot pin 66. As indicated by the phantom lines in FIG. 7, when the lockingpin 72 is removed from the base member, the combination ofside 46 andconnector segment 48 is free to pivot aboutpivot pin 66 in the manner shown in FIG. 11. - In accordance with one form of the method of making the wake tower illustrated in FIGS. 1 through 11, the first and
second base members connectors 76 in the manner shown in FIG. 6. - The
side members first end 84 of first diameter D-1, asecond end 86 of a second lesser diameter D-2 and auniform diameter portion 86 having a diameter D-3 substantially equal to said second lesser diameter D-2. - Using an appropriate forming dye, the tapered swaged portion82 of the swaged tube 82 is strategically formed to produce a tapered swaged portion 82 a and an elongated
uniform diameter portion 86 a (FIG. 3). As illustrated in FIG. 3, swaged portion 82 a is generally oval shaped in cross-section and has a thickness “E”. Swaged portion 82 a has a width W-1, whileuniform diameter portion 86 a has a lesser width W-2. This swaging step is done in a conventional manner using conventional tooling that is of the character well understood by those skilled in the art. - Following the swaging step, the swaged to first tube80 is strategically bent into the desired shape to form a first bent tube that is generally “L” shaped in configuration and generally corresponds to the shape of
member 42 a. - Next,
first connector segment 44 is cast in a conventional manner from a light weight castable material such aluminum and is connected by any suitable means such as welding to the bent tube formed by the swaging step to form a firstwake tower subassembly 42, which generally corresponds to one-half of thestructural assembly 40. - Following the forming of the first wake tower subassembly, a second length of aluminum tubing is swaged and formed in the identical manner described in the preceding paragraphs to produce a
second side 46 a. This done,second connector segment 48 is suitably cast from a light weight metal such as aluminum and is interconnected as by welding wassecond side 46 a to formassembly 46 that generally corresponds to the second half of thestructural assembly 40. - Next, the elongated, uniform diameter portions of the first and second
wake tower subassemblies structural member 40. - After completion of the construction of the
structural member 40 in the manner described in the preceding paragraphs, the structural member is pivotally interconnected with thebase members bores 69 and 62 a and the locking pins are inserted intobores 73 and 64 a. With this construction, when it is desired to pivot the structural member into the forwardly stowed position in the manner illustrated in FIG. 11, lockingpin 72 are removed frombores 73 and 64 a to permit the structural member to pivot about pivot pins 66. - Turning next to FIGS. 12 through 21 an alternate form of the wake tower of the invention is shown and generally designated by the numeral90. This embodiment is similar in many respects to the embodiment shown in FIGS. 1 through 11 and like numerals are used in FIGS. 12 through 21 to identify like components. One of the main differences between this latest form of the invention and the earlier described form resides in the fact that the wake tower slopes rearwardly instead of forwardly and instead of being pivotally movable toward the bow of the boat, is pivotally movable toward the stern of the boat as shown in FIG. 14 of the drawings.
- Referring to FIG. 12 of the drawings, wake tower90 is shown interconnected with a
powerboat 30 of conventional construction having abow portion 30 a, astem portion 30 b and first and second spaced apart gunwales 32 and 34 respectively. In this latest form of the invention, the wake tower includes an upwardly extendingfirst base member 96 that is connected to thefirst gunwale 32 and an upwardly extendingsecond base member 98 that is connected to saidsecond gunwale 34. Thebase members - Interconnected with the base members is a generally U-shaped, upwardly extending structural assembly generally designated by the numeral100. The
structural assembly 100 includes a generally “L” shapedstructural member 102 having a firstcurved side 102 a and a cast aluminumfirst connector segment 104.Structural member 102 is connected to aluminumfirst connector segment 104 by any suitable means such as welding. In a manner presently to be described,connector segment 104 is, in turn, pivotally connected tofirst base member 96.Structural assembly 100 also includes a second generally “L” shapedstructural member 106 having a curved side 106 a and a second, castaluminum connector segment 108 that is connected to second curved side 106 a by any suitable means such as welding.Connector segment 108 is, in turn, pivotally connectedsecond base member 98. - As in the earlier described embodiment of the invention, each of the sides of
structural assembly 100 is first swaged into the desired configuration and then is strategically formed to create an elongated swaged portion having an oval shape (see FIGS. 13 and 15). As indicated in FIG. 14, in this latest form of the invention, thebight portion 110 of thestructural assembly 100 is also generally oval shaped in cross-section. Unlike the earlier described embodiment of the invention, the tow rope TR is directly connected to aconnector 112 that is connected tobight portion 110 proximate the center thereof. - Turning next to FIGS. 17 through 20, a portion of one side of the wake tower of this latest form of the invention is there shown. It is to be understood that the other side of the wake tower is of a similar construction, but is not shown in the drawings in order to simplify the specification. As best seen in FIGS. 17 and 20, each of the base members is provided with a
cavity 114 and each of the connector segments is provided with a pair of spaced apart, downwardly extendingears ear 116 has a bore 116 a formed therein and, similarly, downwardly extendingear 118, which has a length greater than the length of theear 116, has a bore 118 a formed therein. Receivable within bore 118 a is apivot pin 120 about whichside 106 andconnector segment 108 can pivot in the manner shown in FIG. 21. As illustrated in FIGS. 19 and 20,pivot pin 120 extends through alignedbores 123 formed inbase member 98. Similarly, alocking pin 124 is receivable within bore 116 a formed inear 116. Lockingpin 124 extends through alignedbores 125 formed inbase member 98 and, when in position within these openings in the manner shown in FIGS. 17 and 20, prevents pivotal movement ofside 106 andconnector segment 108 aboutpivot pin 120. As indicated by the phantom lines in FIG. 20, when thelocking pin 124 is removed from the base member, the combination ofside 106 andconnector segment 108 is free to pivot aboutpivot pin 120 in the manner shown in FIG. 21. - In accordance with an alternate form of the method of making the wake tower illustrated in FIGS. 12 through 21, the first and
second base members connectors 129 in the manner shown in FIG. 17. - The
side members 102 a and 106 a are each formed individually by first heating to an elevated, annealing temperature a first length of tubing, such as 6061-T6 aluminum tubing that has a diameter of approximately 5 inches. The heated length of tubing is swaged in a conventional manner well known to those skilled in the art to form a first swagedtube 130 of the general configuration shown in FIG. 12. Using an appropriate forming dye, the swagedtube 130 is strategically formed so that it is generally oval shaped in cross-section. This swaging step is done in a conventional manner using conventional tooling that is of the character well understood by those skilled in the art. Following the swaging step, the swaged tofirst tube 130 is strategically bent into the desired shape to form a first bent tube that is generally “L” shaped in configuration and generally corresponds to the shape ofmember 102 a. - Next,
first connector segment 104 is cast in a conventional manner from a light weight castable material such aluminum and is connected by any suitable means such as welding to the bent tube formed by the swaging step to form a firstwake tower subassembly 102, which generally corresponds to one-half of thestructural assembly 100. - Following the forming of the first wake tower subassembly, a second length of aluminum tubing is swaged and formed in the identical manner described in the preceding paragraphs to produce a second side106 a. This done,
second connector segment 108 is suitably cast from a light weight metal such as aluminum and is interconnected as by welding was second side 106 a to form assembly 106 that generally corresponds to the second half of thestructural assembly 100. - Next, the first and second
wake tower subassemblies structural member 100. After completing the construction of thestructural member 100 in the manner described in the preceding paragraphs, the structural member is pivotally interconnected with thebase members bores 123 and 118 a and the locking pins are inserted intobores 125 and 116 a. With this construction, when it is desired to pivot the structural member rearwardly into the stowed position in the manner illustrated by the phantom lines in FIG. 14, lockingpin 124 is removed frombores 125 and 116 a to permit the structural member to pivot aboutpivot pin 120. - Referring to FIGS. 22 through 27, still another form of the wake tower of the invention is there shown and generally designated by the numeral140. This embodiment is also similar in many respects to the embodiment shown in FIGS. 1 through 11 and like numerals are used in FIGS. 12 through 21 to identify like components. The main differences between this latest form of the invention and that earlier described resides in the fact that the wake tower is cast by conventional casting techniques from a lightweight metal such as aluminum or from other suitable castable materials such as plastic.
- Referring to FIG. 25 of the drawings,
wake tower 140 is interconnected with apowerboat 30 of the previously described, conventional construction having a bow portion, a stem portion and first and second spaced apart gunwales. As before, the wake tower includes an upwardly extendingfirst base member 36 that is connected to the first gunwale and an upwardly extendingsecond base member 38 that is connected to said second gunwale. The base members are of a curved configuration and are also preferably cast from a lightweight material such as aluminum or the like. - Interconnected with the base members is a generally U-shaped, upwardly extending structural assembly generally designated by the numeral142. The
structural assembly 142 includes a pair of generally “L” shaped structural members each having acurved side 142 a and a connector segment 142 b that includes a basewall 142 c that closes the lower extremity of thecurved sides 142 a. The connector segments 142 b are pivotally connected to the first and second base members in the manner previously described to enable the structural assembly to be pivoted into the stowed position as illustrated in FIG. 4. More particularly, as earlier discussed herein, theears base cavities 60, the pivot pins 66 are inserted into bores 62 a and the locking pins are inserted into bores 64 a. With this construction, when it is desired to pivot the structural member into the stowed position in the manner previously described, locking pins 72 are removed frombores 73 to permit the structural member to pivot about pivot pins 66. - As best seen in FIGS. 22 and 25, each of the sides of the
structural assembly 140 includes a lower portion having a first width W and an upper portion having a second width W-1 that is substantially less than said first widthW. Structural assembly 140 further includes abight portion 144 that interconnects the upper portions of the sides (FIG. 22). As indicated in FIGS. 22, 23 and 24,bight portion 144 is generally circular in cross-section. At the time of assembly of thestructural assembly 142, the bight portions are interconnected together by any suitable means such as welding (see FIG. 23). As illustrated in FIG. 26, the sides of the structural assembly are generally oval in cross-section. It is to be understood that the two sides of thewake tower 140 are of a similar construction, but only one side a shown in the drawings in order to simplify the specification. - In this latest form of the invention, like the form of the invention shown in FIGS. 1 through 11, the
wake tower 140 further includes a towrope connector member 146 that is connected to and spans upper portion of thesides 142 a. Connected to theconnector member 146 is a conventional type ofconnector 58 to which the towrope “TR” can be connected. - Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
