Not Applicable.
This disclosure relates generally to docks and/or boatlifts for small watercraft, and in particular to such dock and/or lifts for use manually or paddle powered boats, such as canoes, kayaks, etc.
Boat lifts for small watercraft, such as personal watercraft (PWC's), kayaks, canoes, etc. typically include cradle for the watercraft which is bounded on at least two sides by decking. The boat lift, in turn, is often part of a docking system, which provides lifts for several watercraft. A popular boat lift is sold by EZ Dock, Inc. under the name EZ Port® and EZ Port Max®. However, those who have impaired leg function or are wheel-chair bound such boat lifts find it difficult to board and disembark watercraft when docked in such boat lifts. Additionally, boatlifts, such as the EZ Port and EZ Port Max rely on power from the motor boat motor to propel the watercraft onto the boat lift. It is difficult to product sufficient energy in manually powered (or rowed) watercraft, such as canoes, kayaks, etc. to propel the canoe, kayak, etc. onto the boat lift. Thus, the boater will need to exit or disembark the boat at the dock, and then maneuver the boat around the dock to the boat lift and pull the boat onto the boat lift.
It would therefore be desirable to provide a boat lift for small watercraft which would make it easier for those with impaired leg function or otherwise use a wheel chair to board and disembark from small watercraft. It would also be desirable to provide a boat lift in which oar powered or rowed boats (such as canoes, kayaks, etc. can be driven or propelled onto a boat lift.
A boatlift for manually powered (i.e., paddle or oar powered) watercraft is provided. The boatlift is a floating boatlift which comprises an elongate cradle, decking on opposite sides of the cradle, an entrance ramp to the cradle, a first guide rail positioned on one side of the cradle and a second guide rail positioned on a second side of the cradle opposite the first side. The first and second guide rails each comprise an approach portion which extends rearwardly of the boatlift ramp and a boatlift portion extending along the boatlift cradle. Each the guide rail further comprises at least one grab bar extending generally horizontally along the rail. The at least one grab bar is positioned on the guide rail to be at a height where a boater sitting in a paddle or oar powered watercraft could reach the grab bar. Additionally, the first and second guide rails are spaced apart from each other a distance sufficient to allow a paddle or oar powered boat to pass therebetween, yet allowing a boater to simultaneously grab the grab bars of both the first and second guide rails so that the boater can utilize the grab rails to move the boat between the guide rails. The first guide rail is an inside guide rail and the second guide rail is an outside guide rail. The outside guide rail is longer than the inside guide rail. Specifically, the boat lift portion of the inside guide rail has an end spaced rearwardly of an end of the boatlift, whereas, the outside guide rail has an end which is substantially even with the forward end of the boat lift.
In an illustrative embodiment, the guide rails each comprise an upper grab bar and a lower grab bar. The lower grab bar extends at least the length of the approach portion of the guide rails, and can extend to the end of the boatlift ramp (i.e., where the ramp and the cradle meet). The upper grab bar extending at least the length of the boatlift portion of the guide rails, and can extend substantially the length of the guide rail.
The boatlift can further include a barrier rail which is associated with the outside guide rail. The barrier rail comprises a horizontal bar spaced above the top bar of the guide rail, and can be mounted to the boatlift decking or to the outside guide rail. If the barrier rail is mounted to the outside guide rail, then the horizontal bar of the barrier rail is higher than it is if the barrier rail is mounted to the boatlift decking. The barrier rail can be independent of or integral with the guide rail.
The boatlift can also be provided with an entrance/exit assist member located proximate a forward end of one of the guide rails. The entrance/exit assist member comprises a pair of opposed legs extending upwardly on opposite sides of the boatlift cradle and a cross-member extending between the legs and over the cradle. The legs are of sufficient height such that a paddle or oar powered watercraft can pass under the cross-member, and whereby the cross-member is at a height to be reachable by a boater sitting in the watercraft.
In addition, the dock to which the boatlift is adjacent can include at least one bench. The bench is positioned to be adjacent the assist member and extends generally perpendicularly to the boatlift. The bench extends from the dock and over an edge of the dock such that a portion of the bench extends over the boatlift cradle. Hence, a boater can sit at the far end of the bench and be positioned over the watercraft. The boater can then use the assist member to help lower himself/herself into the watercraft.
In one illustrative embodiment, the bench comprises a bench body having a front surface, a back surface, side surfaces, a top surface and a bottom surface. The front surface extends generally parallel to an edge of the dock and defines at least one slot. Illustratively, the bench upper surface can include a first outer portion and a second inner portion; wherein the inner portion is generally parallel to and vertically below the outer portion. This provides a bench with two different heights.
The bench body is supported by legs which are mounted to the decking. The legs can comprise an upper portion and a lower portion which are telescopingly connected. The upper portion can be movable relative to the lower portion such that the effective height of the legs (and hence, the height of the bench) can be changed.
The bench body houses at least one extendable/retractable slide which extends through the at least one slot. The slide is supported by at a support which supports at least one slide within the bench body to be aligned with the at least one slot. The at least one slide is acceptable through the at least one slot, so that it may be pulled from the slot to be used. Illustratively, the bench can include two slides, one being an upper slide and one being a lower slide. The front surface of the bench body would include two slots, one slot for each slide; and two supports with in the body to support the two slides.
Preferably, the slide includes a grab member (such as a handle or tether) at the end of the slide that is exposed. To facilitate extension and retraction of the slide, the support comprises low friction elements; preferably in the form of non-moving guide rails which are made of a low-friction material, such as Teflon.
The slide extends from the bench and reaches across the boatlift. A slide support is positioned on a side of the boatlift opposite the bench to support the slide when extended. The slide support comprises at least one horizontal surface upon which the end of the slide rests when it is extended. The slide can include an arm which extends generally horizontally from the end of the slide. The arm then engages the at least one generally horizontal surface of the slide support when the at least one slide is extended. In an illustrative embodiment, the slide support comprises a pair of upwardly extending rails and at least one generally horizontal rung extending between the rails. The at least one rung comprising the at least one generally horizontal surface, and the slide arm engages the at least one rung.

The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what we presently believe is the best mode of carrying out the invention. Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
A dock system 10 for small watercraft includes a dock 12 and a boat lift 14. The dock 12 can be a floating dock, such as sold by EZ Dock, and which is comprised of a plurality of dock sections 12a which are connected together to form a dock of a desired shape and size. Preferably, the dock system 10 is provided with a gang plank or ramp 13 to facilitate entry onto and exit from the dock 12. A transition member 15 can be provided between the gang plank 13 and the dock 12. Such a dock can be made, for example, in accordance with U.S. Pat. Nos. 5,281,055 and 7,234,608 which are incorporated herein by reference.
The boat lift 14 is secured to the dock 12, in accordance with the docking system from which the dock 10 is made. The boat lift 14 comprises a body 16 having a boat cradle 18 which, as shown, extends the length of the boat lift. A deck 19 extends along the outer edge of the cradle 18 on either side of the cradle 18. The boat lift is preferably a boat lift, such as described in US Pub. No. 20090044740, which is incorporated herein by reference, or which is sold by EZ Dock, Inc. under the name EZ Port Max. An entrance ramp 20 is at one end of the cradle. The cradle 18 has a pair of opposed, inwardly sloping walls 22 with rollers 24 positioned along each wall. The rollers can comprise elongate cylinders 26 (
The boat lift 14 is provided with guide rails 30a,b on either side of the cradle 18. The guide rails 30a,b are substantially the same. However, as will become apparent, the guide rail 30b is slightly longer than the guide rail 30a. The guide rail 30b can thus be considered an “outside” guide rail which is positioned on the far side of the boat lift 14 from the dock 12; and the guide rail 30a can be considered an “inside” guide rail which is on the dock side of the boat lift 14. Although the guide rails 30a,b are shown mounted on the right and left sides of the boatlift, respectively (with reference to
The guide rails 30a,b are longer than the boat lift 14, and include an approach portion 32 in front of the boat lift ramp 20, and a boat lift section 34. In the outside guide rail 30b, the boat lift section of the guide rail extends substantially to the end of the boat lift. The inside guide rail 30a, on the other hand, ends short of the end of the boat lift. As seen in
The guide rails each include a top grab bar 36 which extends substantially the full length of the guide rail 30 and a lower grab bar 38 which extends the length of the approach section 32 of the guide rails. The lower grab bar 38 is essentially level with the boat lift deck 19, and extends substantially the length of the on-ramp section to the cradle 18. The guide rail additionally can include a front pole 40 at the front end of the guide rail 30 to which both the upper and lower grab bars are connected. (
As shown in
As shown in
When the guide rails 30 are mounted to the boat lift 14, the lower grab bars 38 of the approach portion 32 are approximately at the level of the canoe, kayak, etc. so that they can easily be grasped by a boater sitting in the canoe, kayak, etc. Further, the two guide rails are spaced apart a distance which will allow the boat to pass between the rails 30, yet which will allow the boater to grab both rails at the same time. Hence, by grabbing the lower grab bars 38 of the approach portion of the guide rails 30, the boater can propel his/her boat forward with sufficient force to drive the watercraft onto the on-ramp of the boatlift. By grabbing a forward section of the grab bars 36, 38, the boater can continue to propel his/her boat along the boatlift until the watercraft (i.e., canoe, kayak, etc.) is fully on the boatlift. As can be appreciated, as the watercraft is propelled onto the boatlift, the level of the watercraft, and hence, the boater, will be raised. Hence, as the boater moves the watercraft along the boatlift, the boater can change from initially using the lower grab bars 38 to using the upper grab bars 36 of the guide rails 30. When a boater desires to launch the watercraft, the boater need only get into the watercraft, and using the guide rails 30a,b, propels the boat off the boatlift. In the embodiment of
The embodiment of
The dock is further provided with a pair of benches 76a,b positioned adjacent the assist members 70. The benches 76a,b each extend across a portion of the dock 12 so that the benches can be used by people on the dock 12. In addition, the benches 76a,b extend past the edge of the dock and over the decking of the boatlift, such that the edge of the benches are over the gunwales of the boat. In
To use the entry/exit assist, the boat is positioned at the pass-through between the inside guide rails 30a with the boat seats generally beneath the assist members 70. With the boat in position, a boater can seat himself/herself on one of the benches 76a,b and slide over to the edge of the bench. By holding on to the cross-member 74, the boater can lower himself/herself from the bench 76a,b to the boat seat.
An alternative bench 100 is shown generally in
A ladder 110 is positioned on the opposite side of the boatlift 14 from the bench 100. The ladder 110 includes a pair of side rails 112 which extend up from the surface of the boat lift 14 and a plurality of rungs 114 extending between the rails 112. As will be described in more detail below, the bench 100 includes extendable/retractable slides 116a,b which extend across the boatlift 14 from the front surface 104a of the bench 100 to be supported by one of the rungs 114 of the ladder 110. The slides 116a,b are stored within the bench body 104, and extend and retract through the slots 105a,b in the bench body front surface 104a. The slides 116a,b are accessible through the slots 105a,b when the slides are stored in the bench body. The slides can be retracted fully into the slide (and be reached through the slots) or the slide can protrude slightly from the slot when the slide is in a retracted position. As will be described below, when extended, the slides 116a,b reach or extend across the boatlift 14 to enable a disabled boater (such as one who does not have use of his/her legs) to get in and get out of a small boat, such as a kayak or a canoe. To facilitate extending of the slides 116a,b, each slide includes a grip 117. The grips 117 are shown as flexible loops, but could comprise handles, pull rods, etc. The slides also include arms 118 at the end of each slide. The arms 118 extend from the slides such that they are generally flush or level with the top surface of the slides. The arms 118 rest on the rungs 114 of the ladder 110 when the slides are extended. The grips 116 are illustratively mounted to the ends of the arms 118. As can be appreciated, the arms 118, and the connection between the arms 118 and the slides 116a,b are sufficiently robust to support a person on the slide with the slide extended.
The bench 100 is shown in more detail in
Wheel chairs have one of two typical seat heights. Hence, the different heights of the bench top surface enable users of wheel chairs with either seat height to more easily transfer from their wheel chairs to the bench. Thus, one who uses a wheel chair having a higher seat height can transfer from his/her wheel chair to the higher first surface 120a of the bench top 104e; and one who uses a wheel chair having a lower seat height can transfer from his/her wheel chair to the lower second surface 120b of the bench top 104e. Hence, the difference in height between the two benches is designed to enable a disabled individual to elevate himself or herself from the lower bench top 120b to the upper bench top 120a (or vice versa), just by pushing up with his/her arms.
Turning to
Although supports (in the form of cross-members) and rails are shown to maintain the vertical and horizontal position of the slides 116a,b in the bench body 104, the slides could be supported by other means. For example, the slides could be supported by rails, which, could be formed from L-beams, for example. Such L-beams would also be made from a low friction material, such as Teflon. The use of a low friction material avoids the use of moving parts, which may have a shortened life in marine environments. However, if desired, cross-members 122a-c and 126a-c could be replaced with rollers. Alternatively, spaced apart bearing assemblies could be provided on which the slides 116a,b slide.
The use of low friction guides, whether the low friction guide be made from a low friction material or be comprised of rollers or bearing assemblies, allows for the slides to be extended from, and retracted into, the bench body easily. This is relatively important, because when exiting a water craft, the boater will be below, and in front of the slides, and hence, will have to reach up to grasp the slide, and will have to extend the slide behind the boater.
In use, when a boater is entering a kayak or canoe that is positioned in the boat lift 14, the boater will first extend one of the two slides 116a,b until the arm 118 of the slide is positioned on a rung 114 of the ladder 110. With the slide supported at one end by the bench 104 and at the opposite end by the ladder 110, the boater can slide out over the kayak or canoe on the slide 116a,b. Once the boater is over the seat of the kayak or canoe, the boater can lower himself/herself into the boat.
To exit a small boat, the boater will approach the boat lift 14, and position the small boat on the boat lift such that the boater is slightly in front of the bench 100 and ladder 110. With the boater so positioned, the boater can reach up and pull out the slide. The slide will extend behind the boater. When the slide is positioned, the boater can raise himself/herself up onto the slide 116a,b. Once the boater is on the slide, the boater can then scoot over towards the bench body 104.
As noted there are two slides 116a,b. Only one slide will be extended at a time. The slide that is extended will depend on the size of the boat the boater is entering or exiting. If the boat seat is low, the boater may use the lower slide 116b. If the boat seat is higher, the boater may use the upper slide 116a.
To add greater flexibility to the use of the bench 100, the legs 106 are telescoping legs. The legs comprise a lower section 106a and an upper section 106b. Illustratively, the upper leg section is received in the lower leg section, but this could be reversed. The leg sections can include a series of discrete holes and pins which extend through the holes when aligned. Any other alternative structure of changing the effective length of the legs can be used as well. Preferably, the legs allow for a change in effective length of about 5″.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. For example, although the inside guide rail 30a is described to be mounted or secured to the boatlift, the inside guide rail 30a could be secured to the edge of the dock 12. Although the guide rails include upper and lower grab bars, the guide rails could each be provided with a single grab bar. In this case, the single grab bar would preferably be contoured, such that the section of the grab bar in the approach portion of the guide rail is below the section of the grab bar in the boatlift portion of the guide rail. These examples are merely illustrative.
