Abstract
A towel bar attachable to bypass style shower doors. The towel bar has a support bar with two ends engaged with flanged escutcheons. The support bar and escutcheons are located at one side of a door with the escutcheons covering suitably sized and spaced apertures in the door. Two flanged fasteners are inserted into the door apertures from an opposite side of the door to mate with the bar ends. Tightening the fastener biases the flanges toward opposite surfaces of the door to secure the towel bar to the door. The fasteners each have a recessed grip defining handles for sliding the door from the side opposite that from which the bar projects.

BACKGROUND OF THE INVENTION




“Bypass” type sliding shower doors can cover the entry to a shower stall. They often have glass or plastic door panels contained within metal frames which slide along parallel tracks. The doors are typically sized to overlap in the center of the entry. Narrow spacing between the tracks and the overlap prevent water from splashing out between the doors.




Such doors often have towel/grip bars mounted to the frame of each door, one door with a bar inside the shower stall and the other door with a bar outside the shower stall. See Generally U.S. Pat. No. 5,860,538.




Besides providing a place to suspend wet towels for drying, these bars also act as handles for opening and closing the shower doors. Since the doors must be spaced close together to avoid leaking, ordinarily such bars cannot be located on both sides of each door because they would prevent the doors from moving past each other. Thus, a person at one side of the shower stall entryway can easily open only one of the doors, since the other door has no corresponding bar on that side to be used as a handle.




Accordingly, an improved bar assembly for bypass shower doors is needed.




BRIEF SUMMARY OF THE INVENTION




The present invention provides a towel bar assembly for mounting on a door, such as a bypass type slidable shower door, having an opening therethrough. The assembly includes a bar having at least one attachment end, an escutcheon having a front with an axial opening in which the attachment end is disposed, and a back having a flange around a rear opening. There is also a fastener having a back end with a flange around a rearwardly directed recessed grip. The fastener is inserted in the rear opening of the escutcheon and mated with one of the escutcheon and the attachment end so that the flanges define a gap therebetween. The recessed grip is then accessible from the rear of the assembly.




In preferred forms the recessed grip is a cupped surface, the bar also has a second attachment end, and the assembly also has a second such escutcheon and a second such fastener. The fastener preferably has threads which mate with threads on the attachment end.




In another aspect the invention provides a door assembly. There is a door having front and rear sides, and an aperture extending therebetween. There is also a bar having at least one attachment end extending towards the door, an escutcheon having a front with an axial opening in which the attachment end is disposed, and a back having a flange around a rear opening. The flange is of a size such that the escutcheon cannot pass completely through the door aperture.




There is also a fastener having a back end with a flange around a rearwardly directed recessed grip, the fastener is positioned through the door aperture, the fastener flange being sized such that it prevents the fastener from passing completely through the door aperture. The fastener is inserted in the rear opening of the escutcheon and mated with one of the escutcheon and the attachment end so that the flanges clamp the door between them around the aperture. When the parts are so assembled, the grip can be used to reposition the door from the rear side of the door.




These assemblies permit there to be handles than can easily be gripped on both sides of each door, even in a bypass system. Thus, a door can easily be opened even from the opposite side from which the towel bar projects. The assembly achieves this by providing a low-profile grip on one side of the door that extends inwardly through the door panel itself (rather than outwardly).




The foregoing and other advantages of the invention will appear from the following description. In this description reference is made to the accompanying drawings which form a part hereof and in which there is shown by way of illustration preferred embodiments of the invention. These embodiments do not represent the full scope of the invention. Thus, the claims should be looked to in order to judge the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A towel bar


10


of the present invention is used with standard bypass-style shower doors


12


,


14


covering an entry to a conventional shower stall


15


. Each door


12


,


14


is preferably a single panel of glass free from framing at its sides. One towel bar


10


can be suitably mounted to each of the doors


12


,


14


.




The towel bar


10


includes a bar


16


, two escutcheons


18


, and two nut/fasteners


20


. The bar


16


preferably comprises a tubular rod having a region


20


for hanging towels and having two attachment ends


22


,


24


extending substantially perpendicular. The ends


22


,


24


include an engagement member


26


, preferably consisting of external threads.




Each escutcheon


18


is preferably bell-shaped having a front


28


and a rear


30


. At the front


28


an axial bore


32


extends into each escutcheon


18


to define a cylindrical hub


40


supported at its circumference by walls


42


extending to an interior surface of each escutcheon


18


. Each door


12


,


14


has a set of two suitably located door apertures


64


. Each axial bore


32


includes a front engagement member


44


, preferably consisting of internal threads matable with the threads


26


. At the rear there is a large opening


46


of increased diameter than, and concentric with, the axial bore


32


. A circumferential flange


48


extends around the periphery of the rear


30


of each escutcheon


18


. Each flange


48


is sized larger than a corresponding aperture


64


and defines a catch surface


50


, as will be described.




Each fastener


20


includes a front end


52


and a back end


54


, with the front end


52


sized to fit within a corresponding escutcheon


18


through the rear side opening


46


. The front end


52


of each fastener defines a cylindrical hub


56


having an axial opening, such as bore


58


, concentric with the axial bores


32


of the escutcheons. The hub


56


is supported by a plurality of radially extending walls


60


tapering from the front end


52


to an annular surface


62


having a circumference sized to fit within a corresponding door aperture


64


and escutcheon rear side opening


46


.




The end


54


of each fastener


20


defines a circumferential flange


66


of a greater diameter than the annular surface


62


and having a catch surface


68


similar to that of the escutcheons


18


. Also at the back end


54


of each fastener


20


is a recessed grip


70


, preferably in the form of a cupped surface


72


extending inwardly toward a door within the diameter of the annular surface


62


. At the periphery of the cupped surface


72


, a lateral ridge


74


extends outwardly to a back surface


76


of each fastener


20


. The back surface


76


joins the catch surface


68


at a chamferred edge


78


. The axial bore


58


of each fastener


20


includes an internal engagement member


80


preferably consisting of threads matable with the threads


26


of a corresponding towel support attachment end


22


,


24


.




The towel bar


10


is attached to a shower door


14


by inserting the end


52


of each fastener


20


into the corresponding apertures


64


in the door


14


. The apertures


64


are sized to receive the annular surface


62


of the fastener


20


, but have a diameter less than that of the flange


66


. In this way, each flange catch surface


68


will prevent the fastener


20


from passing completely through the door apertures


64


.




The front end


52


of the fasteners


20


will project past the thickness of the doors


12


,


14


and will be disposed within the escutcheons


18


. The front end


52


of the fasteners


20


and the cylindrical hub


40


of the escutcheons


18


are sized so that when assembled, each escutcheon flange catch surface


48


will contact an opposite surface of one of the doors


12


,


14


. The attachment ends


22


,


24


of the towel support


16


can be threaded into the bore


32


in the escutcheons


18


. Each towel bar is secured to the shower doors


12


,


14


by rotating the escutcheons


18


and the fasteners


20


until the catch surfaces


50


,


68


press firmly against each side of the doors


12


,


14


. An optional gasket (not shown) or sealant may be positioned at the catch surfaces


50


,


68


of the escutcheons


18


and fasteners


20


to further ensure that water does not leak through the door apertures


64


.




Referring to

FIG. 4

, a towel bar


10


of the present invention is attached to each door


12


,


14


of a bypass shower door with the bar


16


extending outwardly on the outer door


14


and inwardly on the inner door


12


. The towel bars


10


thus do not interfere with the sliding motion of the doors


12


,


14


because of the narrow profile of the fasteners


20


.




Importantly, each door


12


,


14


may be opened from both sides using either the bar


16


or the recessed grips


70


. The doors


12


,


14


can be opened at the fastener side by inserting a finger or thumb into one or both of the recessed grips


70


and applying a slightly inward and sideways pressure on the cupped surface


72


. Thus, the towel bar


10


of the present invention provides “handles” at both sides of the doors


12


,


14


, while maintaining a sufficiently narrow gap


90


between the doors so that water will not normally leak outside the shower stall at the gap


90


. Also, the present invention permits the towel bar


10


to be mounted directly to a glass or plastic panel, so that no frame is needed for mounting the handle. This reduces material costs and provides for more pleasant looking shower doors. Moreover, the towel bar is not constrained by the size and location of a door frame, such that it can be any suitable length and configuration.





FIGS. 5A-5F

show alternate end connections of the towel bar


10


to the doors


12


,


14


. For each embodiment, both end connections are identical, therefore, only one is shown and described. Similar parts are shown with similar numerals, albeit with a suitable designation such as “A,” “B,” “C” where the part is different.
