Claims
What is claimed is:
1. A ratcheting mechanism for supporting a shower structure
comprising: a member adapted to connect said shower structure to a
shower stem; a plurality of teeth along said member; and a pawl
fixed to said shower structure and adapted to engage said plurality
of teeth to prevent said shower structure from moving downward.
2. A ratcheting mechanism according to claim 1, further comprising
a lever extending from said pawl adapted to selectively disengage
said pawl from said teeth, enabling said shower structure to move
downward.
3. A ratcheting mechanism according to claim 2, further comprising
a spring adjacent said lever adapted to bias said pawl against said
teeth.
4. A ratcheting mechanism according to claim 2, wherein each of
said plurality of teeth is tapered inward toward the bottom of each
tooth and includes a stop at the bottom of each tooth to enable
said shower structure to selectively move upward and lock at each
tooth without said pawl being disengaged from said teeth.
5. A ratcheting mechanism according to claim 2, further comprising
a protrusion at the bottom of said member to prevent said shower
structure from moving beyond said protrusion.
6. A ratcheting mechanism according to claim 1, further comprising
a plate adapted to cover said member.
7. A ratcheting mechanism according to claim 1, wherein said member
further comprises a clamp adapted to secure said member to said
shower stem.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Patent
Application Ser. No. 60/512,351 filed on Oct. 17, 2003,
incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to an improved mechanism to
allow for the ready adjustment of the height of a pendant shower
structure.
[0004] 2. Description of Related Art
[0005] It is well known in the art to attach showering devices,
such as assemblies of multiple showerheads and various moving and
water spraying structures to the existing stem pipe supplying water
to the standard shower plumbing system. Devices have been hung on
open hooks; they have been threaded directly onto the stem or
clamped with various devices to the stem. Because of the
differences in the heights of people using a shower, however, the
hanging heights of the showering devices often require adjustment.
These adjustments have been made, with some difficulty, using screw
clamps and angled joints. There is, however, need for an adjusting
system to change the height of a shower device that is simple and
easy to use, which allows ready adjustments even while in use and
which precludes the need for tools.
OBJECT AND SUMMARY OF THE INVENTION
[0006] It is an object of the present invention to overcome the
shortcomings of the prior art mentioned above. These and other
objects are achieved by the present invention described herein.
[0007] The present invention features an improved height adjustment
mechanism for showering appliances that are attached to the shower
stem. The improved mechanism features a simple, locking ratchet
clamp that can be easily released, adjusted up or down and reliably
relocked.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The present invention is more fully understood by reference
to the following detailed description of an illustrative embodiment
with the drawings identified below.
[0009] FIG. 1 is an illustration of the preferred embodiment of a
showering device that employs the improved height adjustment
mechanism.
[0010] FIG. 2 shows a partially sectioned schematic illustration of
the preferred embodiment of the showering device, illustrating the
adjustment device retracted and extended.
[0011] FIG. 3 is an enlarged detail of spring-loaded ratchet clamps
engaging the rack in the highest position.
DETAILED DESCRIPTION OF THE INVENTION
[0012] Referring to FIG. 1, the present invention is illustrated in
application as a component of an adjustable showering device (1). A
retractable rack (2) connects the attachment clamp (3), which is
clamped onto a standard shower stem, to the showering device (1).
The rack is covered and retained by cover plate (5).
[0013] FIG. 2 illustrates a partial section of the preferred
embodiment of the shower assembly (1), the cover plate (5) has been
removed to show the novel ratchet adjustment mechanism (2). The two
views illustrate the adjustment rack completely retracted and fully
extended.
[0014] FIG. 3 is an enlargement of the preferred embodiment of the
shower bath assembly (1) showing the spring-loaded ratchet clamps
(6) engaged with the adjustable rack (2). The clamps are biased by
metallic or elastomeric springs (7).
[0015] Depressing the two clamps (6) toward the center of the
device releases their engagement with the adjustable rack (2). The
rack can then be lifted up to any engagement position available
along the multiple stops (10) on the rack (2). The weight of the
rack locks the clamps (6) into the rack at each stop. The taper
angles (9) which lead into each stop (10) along the rack allows the
spring-loaded clamps to ride up to the next locking position
without requiring the clamps to be depressed. Thus the rack can be
lifted up easily from a lower position, but lock at each step
against falling downward. The rack is retained, finally, by a fixed
stop (8) at the extreme low position.
[0016] While a preferred embodiment of the invention has been
herein disclosed and described, it is understood that various
modifications can be made without departing from the scope of the
invention.
