Field of the Invention
The present invention relates to pipe smoking devices. More particularly, the present invention relates to base support members for the tubular body member of water pipe smoking devices. Even more particularly, the present invention pertains to pipe apparatus having storage compartments.
Background of the Invention
A water pipe smoking apparatus to which the present invention pertains include those pipe apparatus which do not provide a storage compartment, those pipe apparatus having a cylindrical, weighted base member onto which an elongated cylindrical vessel body is fixedly attached, and those pipe apparatus which have a detachable vessel body, but do not have a weighted base for apparatus upright stability. Typically, the cylindrical vessel body includes a mid-length entry port for attachment of a stem member which comprises the bowl for the smoking substance. The elongated vessel body contains water which filters the smoking substance. In pipe apparatus having a fixedly attached base structure, the cleaning task after use is a drawback from a consumer point of view. Representative of this type of pipe apparatus, is an embodiment with the ornamental aspects of the pipe apparatus depicted in U.S. Pat. No. Des. 265,595. Representative of those pipe apparatus which have a detachable vessel body, but do not have a weighted base for apparatus upright stability, are embodiments taught by U.S. Pat. No. 4,187,885 which teaches a removable sealing device for a water pipe body, U.S. Pat. No. 4,844,383 which teaches a water pipe body removable from a chamber and retained using rubber pieces around the vessel body, U.S. Pat. No. 4,325,390 which teaches a gibbous-like base reservoir that weights and stabilizes the pipe device with a low center of gravity, U.S. Pat. No. 4,170,237 which teaches a removable lower cap that allows access to the lower end of tube 12 for cleaning, U.S. Pat. No. 4,201,230 which teaches a neoprene plug that expands or contracts as required to facilitate removal of the water pipe body, U.S. Pat. No. 4,044,781 which teaches a cap removable from the bottom end of the tube body using a threaded means. U.S. Pat. No. 4,257,432 is of interest for teaching a filter section attached to a base container that is weighted by water and which appears to be removable from the filter section. U.S. Pat. No. 4,108,152 is also of interest for teaching a storage compartment at the upper mouth end of the pipe device.
While the prior art has addressed the pipe apparatus cleaning problem associated with having a fixed vessel member as part of the pipe apparatus, the solutions have not been widely accepted for reasons associated with high cost to produce and with inadequate structure to effect the cleaning task. Also, the need for a storage compartment persist because the locations taught and implemented by the prior art pipe apparatus devices are deemed impractical.
Thus, a need is seen to exist for a weighted base structure which facilitates removal of a tubular vessel member of a pipe apparatus and which provides an optional storage compartment at the bottom end of the weighted base structure.
Summary of the Invention
Accordingly, the primary object of the present invention is to provide a weighted base structure for use with liquid pipe smoking apparatus which facilitates removal of a tubular liquid containing vessel member of the pipe apparatus.
Another object of the present invention is to provide a storage compartment located on the bottom end of a weighted base member of a liquid pipe smoking apparatus.
A more particular object of the present invention is to provide a weighted base structure for use with liquid pipe smoking apparatus which not only facilitates removal of a tubular liquid containing vessel member of the pipe apparatus, but that also provides a storage compartment located on the bottom end of the weighted base member.
A related object of the present invention is to provide a pipe smoking apparatus having any or all of the foregoing objects.
The foregoing objects are accomplished by providing a base member of a liquid pipe smoking apparatus having the form of a cylindrical base that is adapted to accommodate an insert which is designed to detachably retain a tubular vessel member of the pipe smoking apparatus. The insert member is surrounded by a weighted mass, such as cement, or similar substance. The insert facilitates removal of the vessel body to allow the user to better access the lower interior of the vessel body for cleaning purposes. The insert member comprises an insert structure portion having a bottom portion which accommodates a flexible cup that primarily receives and retains the tubular vessel body. The inserted portion of the vessel body expands the flexible cup such that the upper circular rim of the cup will contact a circumferential ridge on the wall of the insert portion upon being pulled upward. Thus, in removing the tubular vessel body, the first tug causes the tight-fitting tubular vessel in the flexible cup to rise upward and stop at the circumferential ridge. For removal of the tubular vessel body from the base, a slightly greater tug is needed to release the tubular vessel body from the tight fitted retained state within the flexible cup. In a variation of the weighted base member, the exterior cylindrical shell of the base is extended downward to provide structure that is formed into a storage compartment for storing articles such as smoking substance. The storage compartment extends from the weighted mass in the base and is formed to be covered with a threaded or friction retained bottom cap member.
Therefore, to the accomplishments of the foregoing objects, the invention consists of the foregoing features hereinafter fully described and particularly pointed out in the claims, the accompanying drawings and the following disclosure describing in detail the invention, such drawings and disclosure illustrating the preferred embodiment in which the invention may be practiced.

Description of the Preferred Embodiment
As discussed earlier, the elongated cylindrical vessel body of a water pipe smoking apparatus includes a mid-length entry port for attachment of a stem member, see FIG. 8 generally, which comprises the bowl for the smoking substance. The elongated vessel body contains the liquid which filters the smoking substance. FIG. 1 illustrates a lower end portion of a tubular vessel body 400. The vessel 400 is open at the lower end and is provided with a beveled bottom lip 401 to encourage easy insertion, as indicated by arrow F1, into insert member 300 of the weighted base assembly 100. Insert member 300 comprises of an insert structure 301 and a flexible cup 320. The outer diameter of vessel wall 402 is designated as d1 and the lesser beveled diameter is designated as d2. The diameter d3 of insert structure 301 is greater than d1 such that a clearance of at least 0.005 inches is maintained. As will be described below, the insert structure 301 not only facilitates insertion, or engagement, of vessel 400 into insert 301 as indicated by arrow F1, the structure also facilities disengagement of the vessel 400 from insert 301 as indicated by arrow F3.
As best seen in FIGS. 2 and 6, insert member 300 is surrounded by a weighted mass W, which is preferably a hardenable cement that, in an initial liquid state, will flow and conform to the space between insert member 300 and the outer shell member 200, including a bottom end 201, for sealing with a suitable epoxy or similar sealant S. The structure of insert 301 provides a bottommost circumferential groove 303 for placement of a bottom cap member 310. Bottom member 310 not only provides a seal to stop the flow of cement during assembly of base 100, but also serves as a smooth bottom surface for bottom 322 of flexible cup 320 which is placed at the bottom of insert 301. Bottom member 310 is kept within groove 303 and is made of a flexible plastic material to allow deformation to allow being fitted in groove 303, where it will reform back to its original shape. The structure of insert 301 is formed, by example, from aluminum, with upper wall portion 301a, see FIG. 2 and FIG. 5, which has a diameter d3, previously discussed, and with a lower adjoining portion 301b, see generally FIGS. 4 and 5, which has a diameter d6 that is greater than diameter d4 of cup 320, see FIG. 3. The junction where the diameter d6 is formed creates a circumferential ridge 302 which retains cup 320, see FIGS. 2 and 6.
As seen in FIG. 3, cup 320 has a rim 321 and a bottom 322. The inside diameter d5 of flexible cup 320 is less than diameter d1 of vessel 400, but is greater than diameter d2 of the beveled end 401. The diameter d4 is variable due to the flexible wall structure of cup 320. Thus, as best seen from FIG. 4, upon inserting vessel 400 beyond upper insert portion 301a, the lesser diameter of beveled end 401 engages easily into cup 320. The outer wall of vessel 400 contact the inner wall 323 of cup 320 to exert an outward force F2 to cause outward deformation of cup 320 toward the wall of lower portion 301b. The continued application of force F1 results in the inner wall 323 of cup 320 to be in a removable contact relationship with outer wall 402 of vessel 400. The material used to make cup 320 is a plastic material that is compatible with the material of vessel 400, which is typically a translucent acrylic material, such that the contact relationship allows a slipping engagement and disengagement of vessel 400. The expanded walls of cup 320 effectively cause rim 321 to be in an aligned position with ridge 302, see FIG. 5. Thus, since the wall 402 of vessel 400 are firmly contacting wall 323 the upward force F3 will tend to carry the flexible cup upward as indicated by arrow F4 until rim 321 contacts ridge 302 to stop the upward motion of the firmly held cup and vessel. Once rim 321 contacts ridge 302 and stops the motion of cup 320 the wall contact relationship becomes a slipping contact relationship such that the vessel continues the upward motion until complete removal from insert 301 is effected.
FIG. 7 shows a modified weighted base embodiment 100A having the outer shell member 200A adapted with a bottom extension structure 201X that forms a storage compartment SC for storing articles such as a smoking substance SS. The storage compartment extends from the weighted mass in the base and, by example, is formed to be covered with a bottom cap member 202 threadedly secured by threads 201a, 202a.
FIG. 8 shows a pipe smoking device 500 adapted to fit either removable base member 100 or 100A. Device 500 is provide with a protruding side port 501 for stem 502 and bowl 503. Stem 502 being held by a holder 504.
Therefore, while the present invention has been shown and described herein in what is believed to be the most practical and preferred embodiment, it is recognized that departures can be made therefrom within the scope of the invention, which scope is therefore not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent apparatus.
