An apparatus for extending, retracting and storage of a large mat used for floating on a water body.
Floating recreational water mats are becoming increasingly popular. Water mats are typically around 4-5 feet wide and 15 or more feet long and 1 to 2 inches thick, making them bulky and difficult to extend onto the body of water, retract from the body of water, to roll up, and to store. Floating mats are typically rolled up by hand for storage and generally require at least two people to roll up due to their size. To retain their shape in a rolled position, straps are typically placed around them when rolled up to keep them in the rolled position.
There is a need for an apparatus assist in the extending, retracting and storage of a water mat. The apparatus as disclosed herein is a device for extending, retracting and storage of a water mat that allows for a single person extend out onto the water body a mat and to roll up the mat after use. The apparatus as disclosed herein also allows for easier storage of a floating water mat.
The apparatus as disclosed herein addresses this and other related needs in the art.
Provided herein in multiple embodiments is an apparatus for extending, retracting, and storing of a water mat. A first embodiment of the disclosed apparatus includes first and second spaced apart support members. Both support members include an upper and a lower end. The first and second spaced apart support members are secured to a boat dock with appropriate fastening hardware.
The first embodiment of the disclosed apparatus includes a connecting member extending between the first and second spaced apart support members proximate the lower end of the support members and first and second slidable members slidably mounted to the first and second spaced apart support members. The first and second slidable members are translatable between the upper and lower ends of the first and second spaced apart support members. The slidable members are capable of translation along the support members with the assistance of at least two slider bearings per side of the apparatus.
The first embodiment of the apparatus also includes a rotatable shaft with a first and second end. Secured by fasteners to the rotatable shaft are two longitudinally extending plates. An edge of the flotation mat is positioned between the two plates and compressed sufficiently to restrain the edge of the mat from becoming disengaged.
The rotatable shaft extends between the upper ends of the first and second slidable members and is used to extend, retract, and store the rolled mat. Secured to the first end of the rotatable shaft is a first rotation member, such as a sprocket. The first rotation member is driven by a drive mechanism, typically a chain or a belt, that is itself driven by a second rotation member, typically also a sprocket.
The second rotation member is driven either manually by a hand crank or is powered by an electric motor. The apparatus as disclosed herein also includes a bracing member that extends between the lower ends of the first and second slidable members. The bracing member complements the rotatable shaft by preventing inward or outward rotation of the first and second support members.
The first embodiment of the apparatus as disclosed herein also includes two mat spool prevention rails that are secured to the bracing member to facilitate even extension and retraction of the flotation mat. The rails are fabricated from high density polyethylene (HDPE). Additionally, at least two roller guides are disposed atop the bracing member to lessen frictional resistance of the mat rubbing against the bracing member during extension and retraction of the mat.
The first embodiment of the apparatus as disclosed herein also includes at least one, and preferably two, lift-assist members each with a first end and a second end. The first end of the at least one lift-assist member mounted to the bracing member and the second end of the lift-assist member is secured to the connecting member. The lift-assist member provides a biasing effect and is operable to prevent undesirable rapid lowering of the first and second slidable members and rotatable shaft when supporting the weight of the flotation mat.
The first embodiment of the apparatus also utilizes at least two belt barriers that are mounted to the bracing member. The belt barriers are operable to flexibly secure the flotation mat when in a fully retracted position. The belts are withdrawn from the casing of the belt barrier and are wrapped around the rolled flotation mat thereby securing it in position. The apparatus disclosed herein also utilizes first and second ends of the rotatable shaft are secured in position with spring loaded sliding pins.
The second embodiment of the apparatus as disclosed herein is configured for mounting to a watercraft. First and second rigid members are utilized for attachment to the underside of deck support cross-members of a watercraft. Each rigid attachment member includes first and second longitudinally opposed ends. The second embodiment also utilizes first and second spaced-apart support members each with an upper and a lower end. The lower ends of the first and second spaced apart support members are pivotally secured respectively to the second ends of the at least two rigid attachment members.
The second embodiment further utilizes first and second lift-assist members each with a first end and a second end. The first ends of the lift-assist members are mounted respectively near the second ends of the first and second spaced-apart rigid members. The second ends of the lift-assist members are mounted respectively near to the first ends of the first and second spaced-apart support members. The lift-assist members aid in the raising and lowering of the first and second spaced-apart support members when supporting the weight of the flotation mat.
The assembly disclosed herein also includes a connecting member that extends between the first and second spaced-apart support members near a mid-point of the support members. The connecting member serves to stabilize the two support members and prevent inward and outward movement of the connecting members. At the upper ends of the first and second spaced apart support members is positioned a rotatable shaft with first and second ends. The rotatable shaft serves to support the flotation mat when full retracted from the body of water and facilitates the extension of the mat onto the body of water.
Mounted to the first end of the rotatable shaft is a first rotation member. An exemplary first rotation member is a sprocket, or similar drive device, that is rotated by for example, a belt or a chain. The drive device also partially surrounds a second rotation member that is mounted to the same support member on the side of the first rotation member. The second rotation member is operably connected to a hand crank or alternatively to a drive motor. The hand crank and drive motor serve to rotate the second rotation member which transfers the rotative power to the first rotation member and onto the rotatable drive shaft.
This second embodiment also utilizes at least one flat on the rotatable shaft with threaded holes for receiving fasteners advanced into the flat. The fasteners are utilized to retain an edge of the mat between first and second compression plates. Locknuts threaded onto the fasteners can be manually tightened to advance the two plates together and compress the edge of the mat so that it cannot easily, or inadvertently, be extricated from the grip of the plates.
The third embodiment of the apparatus as disclosed herein also includes first and second spaced-apart support members. Both support members include an upper and a lower end. An axle member is secured to the lower end of each of the first and second spaced-apart support members. A wheel is mounted to each end of the two axle members to facilitate transport of the apparatus.
The third embodiment also incorporates a connecting member that extends between the first and second spaced apart support members near the lower end of the support members. The apparatus also utilizes a rotatable shaft with a first and second end. The first and second ends of the rotatable shaft are mounted to the upper ends of the first and second spaced-apart support members.
A first rotation member is mounted to the first end of the rotatable shaft for rotation of the shaft. As with the first and second embodiments, an edge of the flotation mat is disposed and compressed between first and second plates, mounted to a flat on the rotation member, to prevent inadvertent release of the edge of the mat. The third embodiment also employs either a hand crank or a motor, as with the first and second embodiments, to rotate the rotatable shaft to facilitate extension and retraction of the mat onto and off the body of water. As with the first embodiment, the third embodiment incorporates rollers to minimize friction between the flotation mat and the connecting member, one or more mat spool prevention rails and belt barriers with retractable straps all of which are mounted to the connecting member.

A third embodiment of the assembly 400 is designed for land-based operation. This embodiment employs first and second spaced-apart support members 402, 404. Both support members 402, 404 include an upper end 406 and a lower end 408. The spaced apart support members 402, 404 are preferably fabricated from materials that are resistant to moisture, salts and UV light. Such materials include, aluminum, stainless steel, engineering plastics and composites.
Spanning between proximate the lower ends 408 of the support members 402, 404 is a bracing member 410. The bracing member 410 has a first end 412 and a second end 414 and is likewise fabricated from a material that is resistant to environmental degradation. The bracing member 410 serves to separate the supporting members 402, 404 and to restrain them in position.
Disposed opposite the bracing member 410 at the upper end 406 of the support members 402, 404 is a rotatable shaft 420 with a first end 422 and a second end 424. The first end 422 is rotatably supported by the upper end 406 of the first support member 402 while the second end 424 is supported by the upper end 406 of the second support member 404. Mounted to the first end 422 of the rotatable shaft 420 is a rotation drive motor 124 for driving rotation of the rotatable shaft. In a preferred embodiment the drive motor 124 drives a sprocket that in turn drives a chain and the chain then drives a second sprocket mounted to the rotatable shaft 420.
A hand crank 122 embodiment is illustrated at
Secured to the lower end 408 of each support member 402, 404 is an axle member 442. These axle members 442 are preferably rigidly attached to the support members 402, 404 by industry standard attachment means for tubular members. A rotatable wheel 446 is mounted at the outer extent 450 of each side of both members 442.
This embodiment also preferably employs rollers (not shown) mounted to the bracing member 410 to minimize the friction between the mat (not shown) and the bracing member 410 when the mat is either being extended or retracted. Additionally, this embodiment utilizes spool prevention rails 456 that are preferably fabricated from high density polyethylene (HDPE). The spool prevention rails 456 serve to minimize uneven winding and unwinding of the mat from the rotatable shaft 420.
This embodiment also employs a belt barrier 460. In a preferred embodiment, two belt barriers are secured to the bracing member and serve to restrain the mat 14 when fully retracted from the body of water 12. The belt barriers 460 include retractable straps 462 that can be withdrawn from the barrier casing 464 for securing an object, such as the mat 14, into position.
A user of the assembly places an edge of the mat between the two compression plates and squeezes the edge tightly between the two plates to prevent inadvertent release of the mat as has been discussed in the first embodiment above. The mat can then be retracted onto the rotatable shaft by using either a hand crank or an electric motor to rotate the rotatable shaft at a speed that allows the operator to maintain equilibrium with each side of the mat. Once the mat is fully retracted onto the rotatable shaft the retractable straps are used to secure the mat into position on the assembly. When it is time for the mat to be extended onto the body of water the operator turns the crank or activates the electric motor to rotate the rotatable shaft in the opposite direction thereby spooling the mat onto the water body.
