1. Field of the Invention
Embodiments of the invention relate to curtain clips that may be used to retain shower curtains, decorative curtains, and the like on a rod.
2. Background of the Related Art
Curtains are in common use for a number of purposes throughout the home. They may be used for privacy, to block sun, or to prevent egress of water from a shower or bath. These curtains normally depend from a rod.
Many curtains, especially bath or shower curtains, include integral rings or eyelets through which the rod may be threaded to allow the shower curtain to depend directly from the rod. In other cases a series of rings are placed on a rod, and hooks depend from or are integral with these rings. The hooks are then mated with the rings or eyelets on the curtain, allowing the curtain to indirectly depend from the rod. In another example clips, rather than hooks, depend from the ring and are secured to a curtain that does or does not have integral rings or eyelets.
Current systems for hanging curtains using ring systems share a common disadvantage. The threading of the rings on the rod is time consuming. Moreover, when hooks are used the curtain may easily lift out of the hook during use, creating a gap and requiring maintenance. Moreover, inserting hooks into rings is also a time-consuming exercise, and it may be particularly difficult for people who are unable to use both hands or who are not able to hold their hands above their head for long periods of time. Many clips may not be useful because their opening points downward, allowing the curtain to slip from the clip and fall.
We provide a system and apparatus designed to allow easy, single-handed suspension of a curtain from a rod. Embodiments provide a unibody clip that includes an aperture at its top. The clip may be slid into a ring or opening on a curtain. Then the clip may be pushed onto a curtain rod. As the clip is pushed onto a curtain rod it deforms to allow the rod to pass through the aperture. After the curtain rod has passed through the aperture the clip returns to its original configuration.
Embodiments provide a securement apparatus, also referred to as a clip, including a unibody member having a bottom conjoined with a first side and a second side, each of said first side and second side forming a top of said unibody member, with the bottom being substantially coplanar with said first and second sides. The first and said second sides each have a shoulder near said top leading each of said first and said second side to abut each other at a central location of said top forming an aperture, and at least one of the first side and the second side is provided with a protrusion, said protrusion configured to direct an ancillary object into said aperture when said ancillary object makes contact with said top and said unibody member is advanced towards said ancillary object; and, the unibody member is resilient and flexible to enable deflection of at least one of the first and second sides to spread the first side from the second side enabling said unibody member to circumscribe the ancillary object, wherein after the ancillary object advances past the shoulders, the first and second sides advance back towards each other to envelope said ancillary object.
In other embodiments the aperture is offset from said central location of said top. The bottom may be round or squared. Each protrusion may be provided with a curvature. The unibody member may be made from a material selected from the group consisting of polypropylene, polystyrene, acrylic, and spring steel. In some embodiments one or more of the first or second sides is provided with an embellishment disposed on or integral with an outer surface of the first or second side.
In some embodiments each shoulder is provided with a bead disposed on an inner surface thereof. In some embodiments each shoulder is provided with a depression disposed on an inner surface thereof, and a bearing configured to fit within an individual depression is placed within each depression and secured in place with a bushing to properly secure said bearing to said unibody member and enable free motion thereof.
We provide clips 1 for use in retaining curtains 19 without the need for separate hooks. Embodiments of the invention comprise at least one clip 1 having a bottom 7, a first side 3a, a second side 3b, and a top 18. Each clip 1 may have a shape including but not limited to approximately circular, oval, rectangular, hexagonal, or teardrop-shaped. Often the place where the sides 3a, 3b meet the bottom 7 is rounded. Where the sides 3a, 3b meet the top 18 may have sufficient curvature to be described as “shoulders” 13 of the clip 1.
A central portion of the top 18 of the clip 1 has an aperture 11 through which a curtain eyelet 21 and a curtain rod 17 may be placed. When in use, the top 18 of the clip 1, and therefore the aperture 11, is on the side of the curtain rod 17 opposite the side from which the curtain 19 depends. In some embodiments, however, the clip 1 is shaped and/or weighted so that the aperture 11 is offset from the central portion of the top 18.
Embodiments may include embellishments 5 disposed on an outer surface of at least one side 3a, 3b, but are not required to include them. For example, as shown in
The top 18 of each clip 1, adjacent to the aperture 11, includes a protrusion 15 extending from each side 3a, 3b. These protrusions 15 serve multiple functions. First, they help a user orient the clip 1 to a rod 17 in a fashion that enables the clip 1 to be pushed onto the rod 17. Second, the protrusions 15 are angled to cause the aperture 11 to open when the top 18 of the clip 1 is pressed against a rod 17.
Significantly, the use of the protrusions 15 in the manner described above enables a user to place a clip 1 on a rod 17 without taking direct action to pull apart the protrusions 15. This allows simple, one-handed operation of the clip 1. So long as the rod 17 is secure to an ancillary structure, the clips 1 may be forced onto the rod 17 with a quick motion. Pressing the top 18 of the clip 1 against the rod 17 deflects the sides 3a, 3b so that as the clip 1 is advanced toward the rod 17 and the sides 3a, 3b circumscribe the rod 17. After the clip 1 has been advanced so that the rod 17 passes the shoulders 13, the resilient, flexible nature of the clip 1 snaps the sides 3a, 3b back to their original shape without plastic deformation to envelop the rod 17. The curtain 19 may be placed on the clip 1 either before or after the clip 1 has been secured to rod 17 by inserting a side 3a, 3b of the clip 1 through an eyelet 21 or ring in the curtain 19.
This apparatus has further advantages. When a user wishes to remove a curtain 19, he is able to remove both the curtain 19 and each clip 1 by grasping the curtain 19 and, in a quick downward motion, pull the curtain 19 and each clip 1 from the rod 17. This is substantially more convenient than prior art systems and apparatuses, in which rings must be removed one at a time from a rod 17, or when one or both sides of the rod must be removed from an ancillary structure to allow closed rings to slide off when a change is desired.
The surface of the protrusions 15 leading to the aperture 11 may be curved, as shown in
At least one shoulder 13 may be provided with a bead 9 disposed on an inner surface of the clip 1, as is shown in
Each bead 9 acts as a mechanical stop to inhibit the rod 17 from advancing up into the aperture 11 when the clips 1 are used to suspend a curtain 19. This reduces the risk of having the clips 1 and curtain 19 fall off of the rod 17. The beads 9, whether bearing types or not, also serve to reduce the friction experienced between the engagement of the clip 1 with the rod 17 so as to enable smooth and uninterrupted slidable motion of the clips 1 about the rod 17 if it is desired to slide the curtain 19 and clips 1 to about the rod 17.
Embodiments may be made of any one of many materials. For example, they may be polypropylene, polystyrene, acrylic, or spring steel. The type of material may vary depending on the use to which a clip 1 may be put; stronger materials may be more suitable for supporting heavy curtains 19. The clips 1 may be made by extrusion, injection molding, press molding, or other means.
Ideally the material will be one that is resilient and flexible enough to allow separation of the top 18 of the clip 1 at the aperture 11 without breaking, while still able to move back into its original shape and support a curtain 19. Of course, those of skill in the art will recognize that in some situations it may not be necessary for a single clip 1 to bear the weight of an entire curtain 19, since in a typical application many clips 1 will be used to support a single curtain 19.
Embodiments may be further understood with reference to the figures.
Those of skill in the art will recognize that further embodiments are within the scope and spirit of the invention.
