The present invention relates generally to a hanger device and, more particularly, to a hanger device including an adjustable mounting bracket that may be sized for mounting to structural support members of various dimensions. The hanger device may be formed entirely of metallic components or it may be formed as a composite structure including both metallic and polymeric components.
The hanger device is illustrated herein with particular reference to a so-called over-the-door hanger constructed for hang mounting over the top edge of a door to support a hook, plural hooks, a hanger holder, a hook rack or a like utility device for supporting clothing or other articles. As described below, the door hanger includes a single hook.
Over-the-door hangers formed entirely of plastic as shown in U.S. Design Pat. No. D445,669 are known. Such hangers may provide adequate hang strength, but they are not adjustable to permit mounting to doors of various thickness dimensions.
Similarly, over-the-door hangers of rod-like construction are shown in U.S. Pat. No. 6,267,257. The rod-like construction may not provide adequate lateral stability and may tend to mar adjacent finished surfaces. In the patent, the free ends of the rod adjacent the door surface are provided with rubber knobs to prevent damage to the door.
U.S. Pat. No. 6,302,365 discloses door hanger devices including hooks on both sides of the door. The hangers are formed of flat components to enhance lateral stability.
U.S. Pat. Nos. 6,749,165 and 6,814,335 disclose an over the door hanger having a U-shape hanger for mounting to a top edge of a door and a downwardly extending support portion extending to a thermoplastic hook. The support portion and the hook are injection molded together with a vertical support member embedded therein.
A hanging cup holder having a mounting arrangement of adjustable width is disclosed in U.S. Pat. No. 4,984,722. The extruded construction includes engaging serrations and grooves that enable adjustment of the mounting width. Adjustable width mounting constructions are also disclosed in U.S. Pat. Nos. 4,872,224, 5,783,319 and 5,803,422.
The following presents a simplified summary of the invention in order to provide a basic understanding of some example aspects of the invention. This summary is not an extensive overview of the invention. Moreover, this summary is not intended to identify critical elements of the invention nor delineate the scope of the invention. The sole purpose of the summary is to present some concepts of the invention in simplified form as a prelude to the more detailed description that is presented later.
In accordance with one aspect of the present invention, a hanger device includes an adjustable bracket having a longitudinal or mounting dimension that may be varied to accommodate support structures of different dimensions. The adjustable bracket includes a bridging element or portion arranged to be supported by and horizontally extend along a top side or edge of a door.
In accordance with another aspect of the present invention, the adjustable bracket is formed of metallic and polymer components that provide desired strength and size characteristics as well as an aesthetically pleasing appearance that also protects finished door surfaces. Accordingly, the hanger may be used in connection with typical residential door constructions with a reduced risk of damage to the door finish.
The bridging portion of the hanger has engaging members formed of sheet metal stock including a flat strip portion telescopically received within a generally flat channel. The metal materials may be selected to provide tensile strength properties that are an order of magnitude greater than those of typical moldable plastic materials. Accordingly, the engaging members dimensions are substantially less than would be required if corresponding strengths were to be provided with a plastic.
The hanger engaging members may also include polymer components for protecting the door finish and/or enabling the utility element to be economically formed by molding directly to the engaging member. Useful polymers include natural and synthetic materials that can be molded and are particularly exemplified by thermoplastics and thermoplastic elastomers.
The foregoing and other aspects of the present invention will become apparent to those skilled in the art to which the present invention relates upon reading the following description with reference to the accompanying drawings, in which:
Example embodiments that incorporate one or more aspects of the present invention are described and illustrated in the drawings. These illustrated examples are not intended to be a limitation on the present invention. For example, one or more aspects of the present invention can be utilized in other embodiments and even other types of devices. Moreover, certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Still further, in the drawings, the same reference numerals are employed for designating the same elements.
Turning to
The hanger 10 includes an adjustable bracket 16 having a mounting portion 18 and a support portion 20. Each of the portions 18 and 20 has an L-shape. The mounting portion 18 includes a depending retention leg or retention element 22 and a horizontally extending engagement member 24. The support portion 20 has a depending carrier leg or carrier element 26 and a horizontally extending engagement member 28. The engagement member 24 is telescopically received in the engagement member 28 to form a bridging element or portion 30.
As illustrated, the door 14 includes a top side 14a, a back side 14b and a front side 14c. The back side 14b and the front side 14c are parallel. The hanger 10 is mounted to the door with the bridging element or portion 30 extending along and supported by the top side 14a of the door 14 as shown in
The mounting portion 18 may be formed of flat sheet metal stock that has been bent to an L-shape with the retention leg 22 extending to the engagement member 24. The engagement member 24 includes a flat strip 24a of generally rectangular configuration and uniform thickness provided at the proximal end of the member as best shown in
The support portion 20 may also be formed of flat sheet stock metal with the carrier leg 26 extending to the engagement member 28. The member 28 is bent or shaped to provide a channel 28a. The channel 28a has flat, downwardly-opening C-shape formed by a pair of spaced, laterally inwardly bent flanges 32 and 34. The flanges 32, 34 are connected by a channel wall 36 as best shown in
The flanges 32 and 34 respectively include co-planar lower surfaces 33 and 35, and the wall 36 has a planar upper or top surface 37. The lower surfaces 33 and 35 extend in a plane that is parallel to the plane of the top surface 37. The lower surfaces 33 and 35 engage the top side 14a of the door 14.
Referring to
The metallic components of the portions 18 and 20 may be formed of any suitable metal, such as series 200 or 300 stainless steel. The flat steel stock may have a thickness of from about 0.020″ to 0.050″, and adequate tensile strength and hang weight loads are achieved with stock of about 0.030″ thickness. The width of the flat strip 24a may be less than an inch, e.g., about 0.75″. The channel 28a is sized to receive the flat strip 24a with a close sliding fit to provide a laterally stable connection with little, if any, vertical or lateral play between the engaged members.
The thickness of the channel 28a is sized to be received with clearance within the space between the top side 14a of the door 14 and the adjacent door frame member or lintel 39 as shown in
The use of the indicated materials, thicknesses and sizes has enabled hanging loads of up to 40 pounds, for example, with acceptable safety margins. These loads may be increased by variation of the dimensions of the hanger device.
The extent of the telescoping engagement of the members 24 and 28 may be varied to provide the bridging portion 30 with an incrementally adjustable longitudinal dimension or extent in the horizontal direction. To that end, the members 24 and 28 are provided with a detent 41 for releasably securing the members 24 and 28 together in an overlying longitudinally fixed position.
The detent 41 includes a pair of laterally spaced projections or bumps 38 and 40 extending downwardly from the member 28 for receipt in rectangular shaped openings 42 in the member 24. The openings 42 are arranged in laterally spaced columns 44 and 46, respectively aligned with the projections 38 and 40. The openings 42 are longitudinally spaced at uniform intervals along at least a portion of the length of the member 24. Accordingly, the incremental longitudinal adjustment of the horizontal length of the bridging portion 30 corresponds with the longitudinal spacing of the openings 42.
The projections 38, 40 and the openings 42 have generally rectangular shapes and peripheral surfaces that closely fit together. The projections and openings thereby provide associated, substantially planar, peripheral surfaces engaging in both the longitudinal and lateral directions. The relative positions of the engagement members 24 and 28 are thereby securely fixed by the detent 41 in the lock position. Of course, further stability is provided by the engagement of associated pairs of projections and openings at laterally spaced locations.
The horizontal length of the bridging portion 30 may be adjusted from an inch or less up to several inches. For residential applications, the bridging portion 30 dimension may varied about 1.25″ to about 2.50″ to accommodate most interior door thicknesses. It is advantageous to form the members 24 and 28 of thin metal stock in order to achieve the desired flexibility and adequate hang strength while maintaining a relatively thin overall construction easily received between the top side of the door and door lintel or molding.
The vertical play of the member 24 engaged within the channel 28a in combination with the flexibility of the members is sufficient to allow for engagement and disengagement of the detent 41 by hand manipulation. That is, the detent 41 may be moved from a lock position with the projections 38, 40 received in openings 42 to a release position with the projections disengaged from the openings. In this manner, the horizontal dimension of the bridging portion 30 and the engagement of the member 24 with the member 28 may be adjusted by pushing together or pulling apart the portions 18 and 20 by hand.
The complete disengagement of the members 24 and 28 is inhibited by a stop tab 48 as best shown in
The retention leg 22 includes a cushion 52 adjacent its distal end for engagement with the back side 14b of the door. The cushion 52 is sized to space the metallic portions of the leg from the finished door surface.
The cushion 52 may be formed of a thermoplastic material or a thermoplastic rubber or elastomer material having suitable compressibility and coefficient of friction. For example, thermoplastic rubber or elastomer materials include materials such as styrenic block copolymers (TPE-S), thermoplastic polyolefins (TPE-O or TPO), thermoplastic vulcanisates (TPE-V or TPV), thermoplastic polyurethanes (TPE-U or TPU), thermoplastic copolyesters (TPE-E or COPE or TEEE), melt processable rubber (MPR) and thermoplastic polyether block amides (TPE-A). Styrene block copolymers have been found to provide the desired physical properties and may be over molded to the metal component of the retention leg 22. To that end, the retention leg 22 is provided with openings 54 through which the elastomeric material extends to form a secure attachment during molding.
The use of thermoplastic rubber or elastomer material enables a wide selection of softness or hardness characteristics. Thermoplastic rubbers may be formulated with softness to hardness values ranging from gel like at 20 Shore OO up to 90 Shore A, and even harder values on the Shore D scale. Preferably, the softer materials enable a higher coefficient of friction to inhibit sliding movement of the retention leg 22 along the surface of the back side 14b of the door 14 and unwanted pivotal movement of the hanger 10. Softer materials also tend to better avoid marring of the door.
The metallic and plastic components of the retention leg 22 cooperate to provide the desired strength, compressibility and friction properties. With regard to the latter properties, the cushion 52 is sufficiently compressible to accommodate slight differences between the horizontal length of the bridging portion 30 and the top side 14a of the door 14. That is, if the detent 41 is not adjustable to exactly conform the length of the bridging portion 30 to the dimension of the top side 14a, the cushion 52 may slightly compress to allow for the excess door thickness.
The carrier leg 26 includes a thermoplastic portion 56 provided by an integral extension of the thermoplastic material forming the J-shape hook 12. The thermoplastic portion 56 has a surface 56a (
The thermoplastic used to form the J-shape hook 12 may comprise any of the known members of the moldable thermoplastics such as polyamide, polybutadiene, polycarbonate, polyethylene, polyester, polyolefin, polypropylene, and polyurethane. Preferred plastics include crystalline thermoplastics such as polycarbonates, styrene acrylonitrile (SAN) and ABS have been found to provide suitably high-strength and durable utility elements.
As noted above, the engagement member 28 extends at a right angle relative to the carrier leg 26. Thus, the legs 22 and 26 are parallel. On the other hand, an acute angle may be provided between the plane of the lower surfaces 33 and 35 of the bridging portion 30 and the plane of the surface 56a. Alternatively, an acute angle may be formed between the engagement member 24 and the retention leg 22. In either case, the legs 22 and 26 are not parallel and extend toward each other at a slight intersecting angle.
If the legs 22 and 26 of the adjustable bracket 16 are not parallel, but form a slight intersecting angle, the legs will be forced slightly apart by engagement with the parallel sides 14b and 14c of the door 14. This will flex the bridging portion 30 and resiliently compress the cushion 52 which will cooperatively bias the detent 41 into its engaged position. That is, the projections 38 and 40 will be biased into the associated openings 42 to more securely fix the relative positions of the portions 18 and 20.

In each of the hanger devices 10, 60 and 70, the primary load bearing components of the adjustable bracket 16 are formed of metallic materials for strength and compactness. Polymeric components are provided for ease of manufacture and protection of engagement with the finished surfaces of the supporting structure. Further, the metallic components are formed of flat sheet metal stock and may be easily manufactured as by bending to the desired shapes. The polymeric components are formed of moldable materials that may be over molded to the metal components through molding openings to better secure the pieces and, as illustrated, to form a portion of the utility device itself.
Referring to
The brackets 16′ are identical in structure and function. Accordingly, only one of the brackets 16′ is described below.
The bracket 16′ has an all-metal construction including a mounting portion 18′ and a support portion 20′. As in prior embodiments, the portions 18′ and 20′ each have an L-shape. The mounting portion 18′ includes a depending retention leg or retention element 22′ and a horizontally extending engagement member 24′. The support portion 20′ has a depending carrier leg or carrier element 26′ and a horizontally extending engagement member 28′. As in prior embodiments, the engagement member 24′ is telescopically received in the engagement number 28′ to form a bridging element or portion 30′.
The retention leg 22′ is adapted to extend along and engage the backside 14b of the door 14 and the carrier leg 26′ is adapted to extend along and engage the front side 14c of the door.
The mounting portion 18′ may once again be formed of flat sheet metal stock that has been bent to an L-shape with the retention leg 22′ extending to the engagement member 24′. The engagement member 24′ is a flat strip shape 24a′ as in prior embodiments.
The support portion 20′ may also be formed of flat sheet stock metal with a channel 28a′ that is substantially identical to that in prior embodiments. However, in this embodiment, the detent 41′ includes four downwardly extending projections or bump 38′ and 40′ for receipt in the rectangular shaped openings 42′ in the member 24′. The increased number of projections 38′, 40′ engaged within the openings 42′ provide additional lateral stability and increased longitudinal strength or resistance to the pulling apart of the portions 18′ and 20′.
The retention leg 22′ once again includes a cushion 52′ adjacent its distal end for engagement with the backside 14b of the door. In this embodiment, the cushion 52′ does not extend around the edge of the retention leg 22′. In this embodiment, the cushion 52′ merely comprises a U-shape layer pad extending along each of the opposed faces of the leg 22′ and connected through the openings 54′.
While the invention has been shown and described with respect to particular embodiments thereof, this is for the purpose of illustration rather than limitation, and other variations and modifications of the specific embodiments herein shown and described will be apparent to those skilled in the art all within the intended spirit and scope of the invention. Accordingly, the patent is not to be limited in scope and effect to the specific embodiments herein shown and described nor in any other way that is inconsistent with the extent to which the progress in the art has been advanced by the invention.
