Boats often have cushions that are detachably mounted at cushion mounting locations. For example, cushions are often detachable so as to allow storage areas located beneath or behind the cushions to be more easily accessed. Other cushions are removable to convert a region of a boat between a cushioned area (e.g., a sundeck or cushioned seating) and a hard platform such as a casting deck.
A prior art technique for detachably securing a cushion to a mounting location involves using a snap fastener. Typically, a button and socket assembly of the snap fastener is secured to a free end of a strap sewn to the cushion, and a stud and post assembly of the snap fastener is secured to a structural component of the boat. Most commonly, the stud is screwed into a metal or fiber glass component of the boat. By snapping the button and socket assembly over the post of the stud and post assembly, the cushion is secured to the cushion mounting location of the boat. However, when used on fiber glass boats, the stud can cause visible damage to the boats' gel coat layers. Further, straps are often viewed as aesthetically unappealing and can be prone to wear.
More robust latching arrangements have also been used to detachably secure boat cushions to cushion mounting locations of boats. However, existing cushion latching arrangements have components that are installed within custom recesses preformed within a structural component of the boat. Therefore, to utilize such latching arrangements on an existing boat style, the structural design of the boat must be modified to incorporate the recesses at predetermined locations. In the case of fiber glass boats, this involves the expense of re-tooling a new mold. Furthermore, existing cushion latch arrangements are often rather large and expensive.
In view of the above, improved latching/fastening arrangements are needed for detachably mounting boat cushions at desired locations on a boat.
Example embodiments described herein generally relate to fastening arrangements for detachably mounting boat cushions at desired locations on a boat.
Aspects of the disclosure may be more completely understood in consideration of the following detailed description of various embodiments of the disclosure in connection with the accompanying drawings, in which:
In one embodiment, the cushion can include a cushioning layer 230 having a resilient construction such as foam. The cushion can also include a substrate layer 235 secured to the cushioning layer. The substrate layer preferably is less resilient than the cushioning layer. In one embodiment, the substrate layer can include a plastic, metal or wood construction. A fabric layer can be provided over the cushioning layer (not shown). A perimeter of the fabric layer can be secured to the underside of the substrate layer by fasteners such as staples. The region where the fabric is secured to the underside of the substrate can form a lower lip (not shown) that extends around the perimeter of the underside of the substrate.
The structural component 220 of the boat to which the female latching element 215 is secured preferably has a generally rigid construction such as aluminum, fiber glass, plastic or other materials. In certain embodiments, the structural component can include a boat platform, a boat seating area, a panel covering a storage area, a sidewall panel, a decking area, or other structures.

The mounting flange 410 has a lead-in opening 415 that is concentric with the axis M such that the lead-in opening 415 is coaxially aligned with the central passage 400 of the split sleeve 300. The lead-in opening 415 is tapered to provide a tapered leading-in surface 420 for guiding the male coupling element 205 through the mounting flange 410 and into the split sleeve 300 during coupling of the male latching element 205 to the female latching element 215. The mounting flange 410 also includes two fastener openings 425 positioned at opposite sides of the lead-in opening 415. The fastener openings 425 are adapted to receive fasteners such as screws that extend through the fastener openings 425 and into a structural component 220 of the boat 100 to which it is desired to mount the female latching element 215. The mounting flange 410 has countersunk regions 430 positioned around the fastener openings 425 so that heads of fasteners inserted through the fastener openings will be inset into the mounting flange 410.
The split sleeve 300 also includes a circumferential groove 500 that extends around the outer perimeter of the split sleeve 300 at a location between the first and second ends. The circumferential groove 500 receives an elastic ring 600 that mounts around the split sleeve. The elastic ring 600 includes a ring notch 605 describing a discontinuity in the elastic ring 600, thereby facilitating with which the circumferential groove 500 receives the elastic ring 600. In one embodiment the elastic ring 600 made of a plastic material, such as molded thermoplastic elastomer (TPE). In other embodiments, the female latching element 600 can have a metal construction. The elastic ring 600 controls/varies the amount of force required to flex the first and second half-sleeves apart during insertion of the male latching element 205 through the split sleeve 300.
In a preferred embodiment, the female latching element 215 has a molded, one piece construction. In one embodiment, the female latching element 215 is molded of a plastic material such as nylon or other plastic materials. In other embodiments, the female latching element 215 can have a metal construction.

The male latching element 205 also includes an enlargement or head 820 integrally formed with the second end 905 of the shaft 800. The head 820 has a maximum outer cross-dimension 825 that is greater than the minor inner cross-dimension, B, of the split sleeve 300 and smaller than the major inner cross-dimension, A, of the split sleeve 300. The head 820 has a dual tapered configuration. For example, the head has a first tapered region 805 that extends from the second end 905 of the shaft 800 to the major outer cross-dimension 825 of the head 820 and a second tapered region 830 that extends from the major outer cross-dimension 825 of the head 820 to an apex 835 of the head 820. The first tapered region 805 increases in cross-dimension as the first tapered region 805 extends from the second end 905 of the shaft 800 to the major outer cross-dimension 825 of the head 820. The second tapered region 830 decreases in cross-dimension extending from the major outer cross-dimension 825 of the head 820 to the apex 835 of the head 820.
It is preferred for the male latching element 205 to have a molded, one piece construction. In one embodiment, the male latching element 205 is constructed of a plastic material such as nylon. Additionally, it is preferred for the mounting flange 810 of the male latching element 205 to be relatively thin. In one embodiment, the mounting flange 810 has a thickness C less than or equal to about ¼ of an inch. In another embodiment, the mounting flange has a thickness C less than or equal to about 3/16 of an inch. In still another embodiment, the mounting flange has a thickness C less than or equal to about ⅛ of an inch.
To install the female latching element 215 to a structural component 220 of a boat 100, a hole 240 is cut into or otherwise provided in the structural component 220 of the boat 100. Preferably, the hole is slightly larger than the maximum diameter of the socket portion of the female latching element 215. Once the hole 240 is provided in the boat 100, the split sleeve 300, with the elastic ring 600 pre-installed thereon, is inserted through the hole 240 such that the shoulder 320 of the mounting flange 410 seats on the structural component 220 of the boat 100. Fasteners are then inserted through the fastener openings 425 of the mounting flange 410 and into the structural component 220 of the boat 100 to secure the female latching element 215 to the structural component 220. As so mounted, the female latching element 215 has a “flush mounted” configuration relative to the structural component 220. By “flush mounted”, it is meant that the structural component 220 of the boat does not have any recess for receiving or otherwise accommodating the thickness of the mounting flange 410.
The male latching element 205 is secured to a cushion 230 by placing a back side 930 of the mounting flange 810 against the substrate 235 of the cushion 230. Thereafter, fasteners are inserted through the fastener openings 1000 and into the substrate 235 to secure the male latching element 205 to the substrate 235. As so mounted, an outwardly facing surface 935 of the mounting flange 810 is slightly recessed relative to the lip provided about the perimeter of the cushion (not shown).
To latch a cushion 210 to a mounting location 225, the cushion 210 is positioned adjacent the mounting location so that the axis N of the male latching element 205 aligns with the axis M of the female latching element 215. The cushion 210 is then moved linearly toward the mounting location 225 so that the shaft 800 of the male latching element 205 is inserted through the lead-in opening 415 of the mounting flange 410 and into the central passage 320 of the split sleeve 300. As the shaft 800 is inserted into the split sleeve 300, the head 820 causes the first and second half-sleeves of the split sleeve 300 to flex away from one another thereby enlarging the minor inner cross-dimension B of the split sleeve 300 so as to allow the head 820 of the male latching element 205 to pass through the second end 405 of the split sleeve 300. Typically, the first and second half-sleeves flex at hinge locations located at the first end 400 of the split sleeve 300. The elastic ring 600 is provided to increase the amount of force required to flex the first and second half-sleeves apart. By varying the elasticity of the ring, the force required to insert the head of the shaft through the split sleeve 300 and to remove the shaft 800 from the split sleeve 800 can be increased or decreased as needed. The insertion process continues until the head 820 of the shaft 800 passes completely through the split sleeve 300 and the first and second half-sleeves flex or snap back toward one another such that the second end 405 of the split sleeve 300 opposes the first tapered region 805 of the head 820.
To remove the cushion 210 from the cushion mounting location 225, the cushion 210 is pulled linearly away from the mounting location in a direction parallel to the axes M and N. As the cushion 210 is pulled away from the mounting location 225, the first tapered region 805 of the head 820 causes the first and second half-sleeves of the split sleeve 300 to flex apart thereby allowing the head 820 to pass through the central passage 320 of the split sleeve 300. After the head 820 passes through the split sleeve 300, the first and second half-sleeves flex back together due to the elasticity provided by the elastic ring 600 and the inherent resiliency provided by the half-sleeves adjacent the hinge locations.
The preceding embodiments are intended to illustrate without limitation the utility and scope of the present disclosure. Those skilled in the art will readily recognize various modifications and changes that may be made to the embodiments described above without departing from the true spirit and scope of the disclosure.
