Detailed Description of the Preferred Embodiments
Before the present invention is described in greater detail, it should be noted that same reference numerals have been used to denote like elements throughout the specification.
Referring to FIGS. 3 and 5, the preferred embodiment of the fitting according to the present invention is shown to comprise a positioning plate 20, an elongate mounting post 30, a hollow annular waterproof member 40, an annular shell member 50, and a holding member 60.
The positioning plate 20 includes a plate member 21 with an outer major wall which serves as a faceplate and which confines a central area 24, and a protruding post 22 which extends in an axial direction from the central area 24. A bore extends from the protruding post 22 in the axial direction toward an upright wall (not shown), and has an inner distal annular wall 25 which is tapped and proximate to the protruding post 22, and an inner proximate annular wall 251 which is disposed in the plate member 21 and which is communicated with the inner distal annular wall 25 so as to define a bottom hole such that a screw fastener 70 passes through the bottom hole for insertion into the upright wall to secure the positioning plate 20 on the upright wall along the axial direction.
The mounting post 30 is elongated in the axial direction, and has a mounting portion 31, a guiding portion 34 opposite to the mounting portion 31, an anchoring portion 32 which is interposed between the mounting and guiding portions 31,34, and a stem portion 35 which is interposed between the mounting and anchoring portions 31,32. The mounting portion 31 has a threaded outer surface for threadedly engaging with the inner distal annular wall 25 to conceal the bottom hole so as to form an integrity of the faceplate with the outer major wall. An operating hole 33 is formed in the guiding portion 34 for engaging a tool, such as a spanner (not shown), to rotate the mounting post 30.
The waterproof member 40 is made of a waterproof material, and is elongated in the axial direction. The waterproof member 40 has an axial hole 45, and proximate and distal annular recesses 47,46 which respectively extend inwardly of a proximate end 44 and a distal end 41 of the waterproof member 40. The proximate and distal annular recesses 47,46 have dimensions larger than that of the axial hole 45 and are communicated with the axial hole 45. In addition, the waterproof member 40 further has an annular neck portion 42 adjacent to the distal end 41, and an annular inclined wall 43 flanking immediately the neck portion 42.
The shell member 50 has two opposite distal and proximate neck portions 51,53 with distal and proximate engaging inner walls 52, 54, respectively, and a length which is slightly smaller than that of the waterproof member 40. The distal neck portion 51 is connected to the neck portion 42 with the guidance of the inclined wall 43, while the proximate neck portion 53 is connected to the waterproof member 40 adjacent to the proximate end 44.
The holding member 60 has an axial hole 66 to receive rotatably the guiding and anchoring portions 34,32 of the mounting post 30, an annular protrusion 64 proximate to the distal end 41 of the waterproof member 40 to be received in the distal annular recess 46 of the waterproof member 40, a skirt portion 63 which extends outwardly of the annular protrusion 64, a holding portion 61 distal to the annular protrusion 64, and a middle portion 62 which is interposed between the skirt portion 63 and the holding portion 61. An annular groove 65 is formed between the skirt portion 63 and the annular protrusion 64 so as to engage the distal end 41 of the waterproof member 40. A screw hole 67 is formed between the middle portion 62 and the skirt portion 63, and extends in a radial direction relative to the axial direction to be communicated with the axial hole 66. In addition, a holding hole 611 is formed through and extends in a direction transverse to the axial direction.
The fastening member 68, such as a screw fastener, is inserted threadedly into the screw hole 67.
In assembly, referring to FIGS. 4 and 5, a screw fixture 80 (see FIG. 3) is first inserted into the upright wall, and the screw fastener 70 is passed through the inner proximate annular wall 251 of the positioning plate 20 from the inner distal annular wall 25 to engage threadedly the screw fixture 80 so as to fix the positioning plate 20 on the upright wall. An adhesive sheet 230 may be attached between the positioning plate 20 and the upright wall. Then, the mounting portion 31 of the mounting post 30 engages threadedly the inner distal annular wall 25 to abut against the screw fastener 70.
Subsequently, the waterproof member 40 is passed through the shell member 50 from the distal neck portion 51 toward the proximate neck portion 53 such that the distal neck portion 51 engages the neck portion 42 for connecting the waterproof member 40 and the shell member 50. The proximate and distal ends 44,41 project outwardly of the proximate and distal neck portions 53,51. In addition, the waterproof member 40 is sleeved on the stem portion 35 of the mounting post 30 such that the proximate end 44 engages sealingly the central area 24 of the positioning plate 20. At this time, there is a clearance 500 formed between the proximate neck portion 53 and the central area 24.
Finally, the holding member 60 is sleeved on the guiding and anchoring portions 34,32 by means of the axial hole 66 to conceal the anchoring portion 32, and the annular protrusion 64 is received in the proximate annular recess 47 of the waterproof member 40 such that the anchoring portion 32 is aligned with the screw hole 67 in the radial direction. The distal end 41 is engaged sealingly with the annular groove 65. There is also a clearance 501 formed between the distal neck portion 51 and the skirt portion 63. Moreover, the fastening member 68 is inserted threadedly into the screw hole 67, and a tip end 681 thereof is tightened with the anchoring portion 32 so as to fix the mounting post 30 relative to the holding member 60.
As mentioned above, since the mounting post 30 is inserted into the waterproof member 40 to engage tightly the protruding post 22 and the holding member 60, and since the waterproof member 40 engages sealingly the positioning plate 20 and the holding member 60, the holding member 60 is secured to the positioning plate 20 very firmly so as to prevent swaying during use. In addition, by means of the waterproof member 40, the fitting of this invention, especially the fastening member 70, can be protected from moisture.
It is noted that only one fastening member 70 is needed to fix the positioning plate 20 on the upright wall, thereby resulting in convenient assembling of the fitting.
Referring to FIG. 6, when two fittings of this invention are mounted on an upright wall, two ends of a support member in the form of a transverse rod 90 can be held within the holding holes 611 such that a washcloth 100 can be hung on the transverse rod 90.
Referring to FIG. 7, a support member in the form of a holding ring 91 can be held in the holding hole 611 of the fitting for hanging a towel 101 thereon.
Referring to FIGS. 8 and 9, another preferred embodiment of the fitting according to this invention is shown to include a positioning plate 26 which differs from the aforementioned embodiment in that the positioning plate 26 includes a positioning shell 29 and a positioning seat 27 which is received in the positioning shell 29. The positioning shell 29 has a through hole 291 for passage of the mounting post 30. The positioning seat 27 has the inner distal annular wall 271 and the inner proximate annular wall 272. A washer 28 is disposed between the positioning seat 27 and an upright wall (not shown) so as to secure the fastening member 70 onto the upright wall.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
