PARTICULAR ADVANTAGES OF THE INVENTION
(12) The present hanger can be securely attached around a rod to support a portion of the weight of two articles one on each side of the hanger and it does not derail and detach altogether from the rod on which the hanger is installed when a tucking or pulling force is applied imperfectly on at least one of the two articles, i.e., when the tucking or pulling force is not aligned perfectly in a direction to cause the movement of the hanger in a desired direction. Therefore, the user can use the articles, e.g., shower curtain and liner supported on the hanger without fear of detaching at least one of them from the rod upon which the articles were supported and having to re-seat the hanger on the rod. The present hanger can be securely attached around a rod to support a portion of the weight of two articles one on each side of the hanger while allowing the hanger to traverse the rod smoothly without excessive friction that can cause one or more of a plurality of such hangers that support the two articles to derail and stop functioning properly.
(13) The present hanger includes only two parts, a flat supporting structure and a cylindrical roller. Both parts are easy to manufacture by three-dimensional (3D) printing or injection molding and intuitive to assemble and install on a rod. To support a shower curtain and a liner, a plurality of the present hangers are used to support articles in the form of sheets with each hanger bearing a portion of the weight of the shower curtain and the liner. By unseating the prongs from the receptacles in the roller, the hangers and attached curtain and liner can be easily detached from the rod for cleaning. To detach a hanger from a rod, one is merely required to pull one prong against the roller in a direction away from the roller such that the roller can be freed from the hanger, releasing the rod from being confined within a supporting structure coupled with a roller.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
(14) The term about is used herein to mean approximately, roughly, around, or in the region of. When the term about is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term about is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).
(15) Shower curtains are commonly used to prevent water from splashing outside the bathing area while additionally providing aesthetic value and privacy to their users. Traditional shower curtain hanger systems often consist of basic hooks or rings attached to a curtain rod, which can lead to various issues such as instability, difficulty in curtain attachment and detachment and unappealing aesthetics. In many cases, users experience the frustration of a curtain falling off its hangers or hangers falling off their rod during use, resulting in wet floors and frustrating showering experiences.
(16) To address these drawbacks, there have been attempts to improve the design and functionality of shower curtain hanger systems. These include mechanisms such as snap-on hooks, adjustable clips, double-hook arrangements and rollers on spindle as employed by Hanley, Carpenter and Angevine. However, these solutions often present their own challenges, including complicated installation, limited adaptability to different curtain types, instability of the hanger on rod and a propensity to cause wear and tear on the curtain material. Thus, there is a need for a novel shower curtain hanger system that overcomes the limitations of existing solutions and provides enhanced stability, ease of use and aesthetic integration with modern bathroom environments.
(17) FIG. 1 is a front view of a roller and a supporting structure 4 configured to be coupled to the roller according to one embodiment of the present hanger 2. FIG. 2 is a bottom front perspective view of a roller and a supporting structure 4 configured to be coupled to the roller according to one embodiment of the present hanger 2. FIG. 3 is a front view of a roller and a supporting structure configured to be coupled to the supporting structure, depicting the supporting structure having been coupled to the roller according to one embodiment of the present hanger 2. FIG. 4 is a bottom perspective view of a roller and a supporting structure 4 configured to be coupled to the supporting structure, depicting the supporting structure 4 having been coupled to the roller according to one embodiment of the present hanger 2. Shown herein is a single hanger for ease of description of the ensuing embodiments. In a typical application, a plurality of hangers, e.g., a dozen, are required. However, each hanger functions similarly to its adjacently-disposed hanger, i.e., to support a portion of the total weight of one or more sheets while allowing the one or more sheets to be suspended or moved along a rod 32. The hanger includes a roller 6, a supporting structure 4 configured for supporting the roller and a pair of hooks 10 extending from the supporting structure 4. Each hook 10 is configured to receive an article, e.g., a shower curtain or liner and includes an inflection point 12, a function of which would be apparent in the ensuing description. An inflection point, as used herein, is characterized by a valley in part having two side edges that are substantially rectilinear. In one embodiment, the inflection point includes an angle 18 of about 22.5-135 degrees. The roller 6 includes a width and is essentially a cylindrical component having a receptacle 30 disposed along a central axis on each widthwise end of the roller 6 providing a total of a pair of opposingly-disposed receptacles 30. The hanger 2 further includes a pair of prongs 8 extending inwardly from the supporting structure 4 towards one another. Each receptacle 30 is configured to receive one of the prongs 8. Each prong 8 preferably includes a length 42 sufficiently large to secure one end of the roller 6 but not too prominent as not to jeopardize the ease of attaching the roller 6 to the supporting structure 4 or detaching the roller 6 from the supporting structure 4. In one embodiment, the ratio of the width 40 of the roller 6 to the length 42 of the prong 8 is about 5.618 mm/26.5 mm or 1/4.7. In the embodiment shown, the supporting structure 4 is essentially a planar structure with two flat parallel surfaces and features that define a U-shape and the prongs 8 which protrude from the U-shape structure defined in two directions within these flat surfaces. The hanger can be installed on a rod 32 or taken off easily from a rod 32. To remove the hanger from a rod, a user simply unsnaps a prong 8 from a roller receptacle 30. To install the hanger around the rod 32, the prong 8 is re-snapped back in the receptacle 30. The supporting structure is preferably one which provides sufficient strength to support the roller 6 while allowing the arms of the structure from which the prongs 8 extend to bend in a direction perpendicular to the flat surfaces while being manipulated using one's fingers from both hands to allow a prong to be seated or reseated in a receptacle 30 of the roller 6. In contrast, Hanley's hanger is less intuitive for a user to install on a rod and requires one arm to be rotated 180 degrees in order to provide space for the roller to be slipped over the rod and then the arm must be rotated back to be secured in a cradle. The use of a roller secured with a pair of prongs 8 eliminates the need for a spindle, e.g., one disclosed in Hanley, Carpenter and Angevine. The use of a spindle to support a roller significantly increases the friction between the roller and the spindle to which the roller is coupled.
(18) FIG. 5 is a front view of a roller and a supporting structure configured to be coupled to the supporting structure, depicting the supporting structure having been coupled to the roller and that a first article 26 and a second article 28 are being supported by the hanger 2 according to one embodiment of the present hanger. The hooks 10 are disposed symmetrically about a central plane 22 of the supporting structure 4 and therefore the first article 26 and the second article 28 can be interchangeably supported on either one of the hooks 10 equally distanced from the central plane 22 of the supporting structure 4. Each of the first article 26 and the second article 28 can be a shower curtain or a liner. By balancing the weight of the two articles 26, 28, the hanger 2 is less likely to tip in a direction about the rod 32 when the user pulls on the curtain to open and close it before and after showering. This reduces the possibility of the hanger 2 detaching from the rod although the gap 14 shown in FIG. 2 is already small, i.e., with the center of gravity of the hanger 2 already closely approximating the center of gravity of the rod. A pleasing appearance can be achieved by balancing the weight of the two articles 26, 28 to ensure that the articles hang in a vertical plane without tipping and sagging. A plurality of apertures, holes or eyelets 24 are disposed near a top edge of a shower curtain or a liner 26, 28 along the entire top edge to properly distribute the weight of the article 26, 28. In one embodiment, the supporting structure is a U-shaped structure, wherein the roller is coupled with the U-shaped structure about the rod to form a gap 14 around the rod 32 to enable rolling of the hanger 2 along the rod 32 with limited departure from the rod 32 if the roller 6 gets detached from the rod 32. The small gap 14 between the rod 32 and the supporting structure 4 causes the hanger 2 to tend to return to its operational position even when the roller 6 has lost contact momentarily with the rod 32, e.g., when inadvertently lifted by a sufficiently stiff installed liner 26, 28. A complete detachment of the installed hanger 2 due to normal use is highly unlikely as the hanger 2, while installed, positively surrounds the rod 32. The rod 32 typically comes in a diameter of 1-1.25 inches. In one embodiment, the ratio of the gap 14 to the radius of the rod is about 2.366 mm/15.0655 mm or 0.16 to 2.366 mm/12.7 mm or 0.19. In one embodiment, the roller includes a widthwise cross-sectional profile 20 such that the roller contacts the rod at only two points 16 as shown in FIGS. 3 and 5, severely reducing the friction imparted on the roller 6 by the rod 32 if the roller 6 becomes inadvertently locked in its rotary motion with respect to the prongs 8. By restricting the opening 34 made between a hook 10 and the supporting structure 4, an article 26, 28 disposed in the hook 10 can be retained. By disposing a shoulder 36 in the part of the supporting structure 4 prior to extending it into a hook 10 at an angle to the shoulder 36, the shoulder 36 prevents an inadvertently lifted article 26, 28 from easily exiting the hook 10 as the bottom portion of the eyelet 24 would come into contact with the shoulder 36 if the article 26, 28 is lifted vertically. In order to remove an article 26, 28 at an eyelet 24 from a hook 10, a user would need to consciously align the eyelet 24 with the hook 10, reducing the possibility that the article 26, 28 can be inadvertently detached. In one embodiment, the horizontal distance 38 between an article 26, 28 and an edge of a shoulder 36 is about 0.28 inches. In one embodiment, the width 40 of the roller 6 is about 1 inch. In one embodiment, the length 42 of a prong 8 is about 0.22 inches. In one embodiment, the thickness 44 of supporting structure 4 is about 0.16 inches. The roller 6 and the supporting structure 4 can be constructed from Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS), Acrylic, Polycarbonate (PC) or any combinations thereof. Other moldable plastics may be considered. Either a roller 6 and/or a supporting structure 4 may be constructed in various colors or surface patterns for aesthetic purposes.
(19) FIG. 6 is a front view of a roller and a supporting structure configured to be coupled to the roller according to one embodiment of the present hanger. FIG. 7 is a bottom front perspective view of a roller and a supporting structure configured to be coupled to the roller according to one embodiment of the present hanger. FIG. 8 is a front view of a roller and a supporting structure configured to be coupled to the supporting structure, depicting the supporting structure having been coupled to the roller according to one embodiment of the present hanger. FIG. 9 is a bottom perspective view of a roller and a supporting structure configured to be coupled to the supporting structure, depicting the supporting structure having been coupled to the roller according to one embodiment of the present hanger. Instead of contacting the rod 32 at two points as shown in FIGS. 3 and 5, the roller 6 shown in FIGS. 6-9 assumes a profile that more closely matches the rod 32 profile for about a quarter of the circumference of the rod 32. This roller profile was found to be providing a roller-rod contact that is even quieter when a roller 6 along the rod 32 than the profile shown in FIGS. 3 and 5.
