DETAILED DESCRIPTION

As shown in FIGS. 1 and 2, a curtain 5 is supported on a curtain rod 7 by means of split curtain grommets 10. Each grommet 10 has a vertical split 12 at the top thereof that is vertically aligned with a split 6 in the curtain 5. The splits 6 in the curtain 5 may extend vertically above the grommets 10 as shown in FIGS. 1 and 2, or may not extend above the grommets in embodiments in which the upper edge of the curtain does not extend above the upper portions of the grommets 10. As shown in FIG. 2, each grommet 10 has a liner hook 40 for supporting a curtain liner 8 by means of liner grommets 9 installed on the liner hook 40.
The curtain 5 may be a window curtain, shower curtain, or the like, and may be made of any suitable type of material. The liner 8 may be a shower curtain liner of any suitable design and material, such as a conventional water-impermeable plastic film or water-resistant or impermeable fabric layer. Alternatively, the liner 8 may be provided in the form of a window curtain liner that may provide additional light blocking for a window curtain. The curtain 5 may be of any suitable length, width and thickness, and any suitable number of grommets may be used.
FIGS. 3-12 illustrate various features of a split curtain grommet 10 in accordance with an embodiment of the present invention. The split curtain grommet 10 includes a front ring 20 having a front face 21 and a rear face 22. In the embodiment shown, optional rear recesses 23 are provided in the rear face 22 of the front ring 20. As shown most clearly in FIGS. 4, 10 and 11, multiple connecting pins 24 extend rearwardly from the rear face 22 of the front ring 20. As more fully described below, the connecting pins 24 engage within aligned pin-receiving holes 34 in a rear ring 30. The front ring 20 includes an interior annular ring 25 that forms the inner diameter of the front ring 20 as well as the overall inner diameter of the split curtain grommet 10. A vertical split 26 is provided at the top of the front ring 20 and is aligned with a vertical split 36 in the rear ring 30 to provide the vertical split 12 in the curtain grommet 10. The front ring 20 has a radial outer edge 27 forming an outer diameter of the front ring 20.
The rear ring 30 of the split curtain grommet 10 has a rear face 31, a front face 32, and an inner diameter 33. Multiple pin-receiving holes 34 extend between the rear and front faces 31 and 32 of the rear ring 30, and are aligned with the connecting pins 24 of the front ring 20 when the front and rear rings are assembled together. In the embodiment shown, each hole 34 has a portion having a diameter similar to that of the corresponding pin 24, and a countersunk portion having a larger diameter. However, each hole 34 may alternatively have a constant diameter along its entire length. The rear ring 30 has a radial outer peripheral edge 35 forming the outer dimeter of the rear ring 30 as well as the outer diameter of the split curtain grommet 10. A hook support projection 37 is provided at the bottom of the rear ring 30 extending horizontally outward from the rear face 31. The hook support projection 37 includes a retaining hole 38 and a retaining slot 39.
A liner hook 40 is connected to the rear ring 30 by engagement with the hook support projection 37. The liner hook 40 includes a hook end 41 and an attachment end 42 having a retaining pin 43 with flexible attachment fingers extending therefrom. The resilient fingers of the retaining pin 43 can be pinched inwardly toward each other when the attachment end 42 of the liner hook 40 is inserted in the hole 38 of the hook support projection 37. In the embodiment shown in FIGS. 3-12, the liner hook 40 is rotatably mounted in the hook support projection 37 of the rear ring 30. As most clearly shown in FIGS. 6 and 12, the liner hook 40 can rotate around a vertical axis from the extended position shown in FIG. 6 to a flattened position shown in FIG. 12 in which the hook 40 lies in a plane that is substantially parallel with a plane defined by the rear face 32 of the rear ring 30. The flattened or stowed positions of the hooks 40 facilitates packaging, storage and transportation of the grommets 10 and curtains 5. Alternatively, a non-rotatable or stationary liner hook may be used, or the liner hook may be eliminated as described below.
FIGS. 13 and 14 illustrate an embodiment of a split curtain grommet 110 without a liner hook. The split curtain grommet 110 may be similar to the split curtain grommet 10 shown in FIGS. 3-12, except the hook support projection 37 and liner hook 40 are eliminated.
The grommet 10 may be relatively large in size and its upper split 12 or gap may be aligned with the split 6 or gap in a portion of the curtain 5 located at or above the grommet 10. In the embodiments shown, the top split 12 of the grommet 10 typically has a slight gap, e.g., from 0.1 to 2 or 3 mm, or from 0.5 to 1 or 1.5 mm. However, any other suitable size gap may be used, or a slit may be provided in which the opposing slit faces contact each other. The split 6 or cut in the curtain 5 above the gap or split 12 of the grommet 10 may be made by any suitable means such as scissors, knives, laser cutting and the like. The fabric may be heat sealed, or may be sewn or otherwise finished.
When the front and rear rings 20 and 30 of the grommet 10 are snapped together or otherwise attached to each other, only the exterior surfaces 21 and 31 may be visible after the grommet 10 is installed on a curtain 5, i.e., the interior surfaces 22 and 32 may be hidden.
The front 20 and rear 30 rings of the grommet 10 are attached to each other by inserting the pins 24 of the front ring 20 into the corresponding holes 34 of the rear ring 30. A snap-fit may be provided in which the front 20 and rear 30 rings of the grommet 10 are secured together through contact between the pins 24 and corresponding circular holes 34. Although cylindrical pins 24 and holes 34 are shown in the figures, any other suitable shapes and configurations may be used in place of, or in addition to, the pins 24 and holes 34. For example, the pins and holes may be square, slots, arched sections or the like.
During installation of the grommets 10 on a curtain 5, the curtain 5 may be cut to provide holes having diameters that are larger than the inner diameter of the grommet 10 but smaller than the outer diameter of the grommet 10. The curtain fabric thus does not extend into the interior circle of the grommet 10, but may be clamped or otherwise secured between the front 20 and rear 30 rings of the grommet 10. In certain embodiments, the curtain fabric extends radially inward of the pins 24 and holes 34 of the grommet 10, and small holes, cuts or punctures may be provided in the fabric to allow the pins 24 to pass therethrough and engage with the circular holes 34. Such cuts made to the curtain fabric may be made by any suitable means, and may typically be made prior to installation of the front 20 and rear 30 rings of the grommet 10 onto the curtain 5.
The grommets 10 may be made of any suitable materials that are sufficiently flexible to allow the grommet 10 to flex in order to be installed on a rod 7, but which have sufficient structural integrity to retain the grommets on the rod under the weight of a curtain 5. For example, the grommets 10 may be made of plastic, metalized plastic, or the like.
