DETAILED DESCRIPTION OF THE INVENTION
In FIGS. 1-6, a two-piece clip device comprises a wedge clip component 20 and a groove clip component 30 for sliding together with one component on each side of a sheet of material 40 to tie down the sheet of material.
An elongated triple tapered groove clip 30 component is positioned on one side of a sheet of material 40. The groove clip component comprises a flat outer bottom portion 38 for bearing indicia 39 thereon, as shown in FIG. 6, and a top surface having a triple tapered groove 33 open along the length of the top surface, as shown in FIG. 2. The groove tapers inwardly from side to side from a wide front opening in a front face 32 of the groove clip component to a narrow back opening in a back face 31 of the groove clip component, and tapers from a low front opening at the front face 32 to a high opening at a back face 31, and also tapers from a narrower top slot opening to a wider flat groove bottom surface 36 of the groove to form sloping inner sides 34 and 35 of the groove.
A mating elongated triple tapered wedge clip component 20 is positioned on an opposite side of the sheet of material 40, aligned for engagement with the groove clip component 30 to bind a portion of the sheet of material 40 therebetween. The wedge clip component comprises a triple tapered wedge portion with a flat wedge bottom 26, as shown in FIG. 5, which slides into the mating triple tapered groove 33 of the groove clip component 30 with the flat wedge bottom 26 and the flat groove bottom 36 in parallel alignment. The wedge clip component further comprises an upwardly protruding loop 27, shown in FIGS. 1, 2, 4, and 5, at an insertion end 21 of the wedge clip component 20 for gripping the wedge clip component to slide the wedge clip component 20 into the mating triple tapered groove 33 of the groove clip component 30 and for attaching a tie down element 50, such as a rope or cord, through the opening 23 of the protruding loop 27 for tying down the sheet of material 4. A loop bottom 26A of the upwardly protruding loop is tangent to the flat surface of the flat wedge bottom 26 of the triple tapered wedge clip portion, so that the flat wedge bottom 26 is aligned with the flat groove bottom 36 of the groove clip component 30 during an entire insertion of the wedge clip component into the groove clip component with the upwardly protruding loop 27 above the wedge clip component for gripping. The triple tapered wedge portion tapers from a narrow insertion end 21 insertable in the wide front opening of the front end 32 of the wedge clip component 30 to a wide opposite binding end 22 which is engaged by the low front opening of the back end 31 of the groove clip component 30 after insertion of the wedge clip component in the groove clip component. The wedge clip component also tapers from a high insertion end 21 which engages the high back end 31 of the groove clip component after insertion to a low binding end 22 which engages with the low front opening of front end 32 of the groove clip component after insertion. The wedge clip component outer sides 24 and 25 taper from a narrow top to a wider flat bottom to form sloping outer sides so that the sloping outer sides 24 and 25 of the wedge clip component engage the sloping inner sides 34 and 35 of the wedge clip component 30 after insertion and the flat wedge bottom 26 engages the flat groove bottom 36 after insertion thereby forming a two-piece clip device to bind any desired portion of the sheet of material 40 between the wedge clip 20 component and the groove clip component 30 with the portion of the sheet of material 40 sandwiched between the sides and the bottoms of the clip components. A series of two-piece clip devices can be spaced apart around a sheet of material at any desired locations on the sheet of material, each engaging a portion of the sheet of material and each of the protruding loops receiving a tie down element 50 attached thereto to tie down the sheet of material, with each of the two-piece clip devices having a length and width sufficient to bind a portion of the sheet of material and securely hold it down without tearing the sheet of material.
The wedge clip component and groove clip component are each preferably fabricated of a synthetic nylon material so that the components slide easily and resist weathering.
In a preferred embodiment, as shown in FIG. 1, the sheet of material comprises a sheet of material 40 with a grid pattern of intersecting reinforcing elements 41H and 41V formed in the sheet of material and the two-piece clip device has a width sufficient to engage a plurality of reinforcing elements and a length sufficient to engage a plurality of reinforcing elements.
The sheet of material 40 may be a sheet of cover material for a boat and a series of the two-piece clip devices are positioned as desired on the sheet of cover material adjacent to tie down locations on the boat to be covered. In this embodiment, the sheet of cover material for a boat comprises a sheet of synthetic material with a grid pattern of intersecting horizontal and vertical reinforcing elements formed in the sheet of material and the two-piece clip device has a width sufficient to engage a plurality of vertical reinforcing elements 40V and a length sufficient to engage a plurality of horizontal reinforcing elements 40H when the two-piece clip is attached with a long centerline of the two-piece clip in a vertical orientation.
In use, the sheet of material may be a sheet of cover material and a series of the two-piece clip devices are positioned as desired on the sheet of cover material adjacent to tie down locations on an object to be covered. The user places the wedge groove component on one side of a portion of the sheet of material, and while holding the wedge groove component in one hand, grips the upwardly protruding loop on the wedge clip component with the other hand on the other side of the sheet of material, and slides the wedge clip component into alignment with the wedge groove component so that the two components mate with the portion of the sheet of material sandwiched between them and secured by a tight friction fit. A tie down element such as a rope or cord is then inserted through the opening in the upwardly protruding loop on the wedge clip component and secured to a tie down position on the object to be covered. The user can then proceed to position a series of clip devices at desired intervals on the sheet of material to correspond to the other tie down positions on the object to be covered, tying each clip to its respective tie down location with a tie down element until the entire sheet of covering material is secured on the object to be covered. To release the clip, the user slides the wedge clip component toward the back end of the wedge groove component, disengaging the covering material.
It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and that various modifications may be made thereto without departing from the spirit of the invention as claimed.
