Table accessory for a toilet

Abstract

A table carried at the distal end of a table leg that is configured for anchoring entirely on a toilet. The table leg is anchored at its proximal end to an upside-down J-bracket configured to couple with the rim of a toilet bowl. A J-bracket typically includes a clamping mechanism to horizontally squeeze the rim. Table elevation above floor level may be adjusted by way of a telescopic table leg, and/or a coupling mechanism between the proximal table leg end and the J-bracket. Horizontal orientation of the table top surface may be maintained by an anti-twist mechanism and an anti-roll mechanism.

DETAILED DESCRIPTION

(10) With reference to FIG. 1, the present invention provides a table assembly, generally indicated at 100, which may be supported entirely by a commercially available toilet, generally 104. For background/reference, toilet 104 includes a toilet bowel 108, a seat 112 (illustrated in a raised position), and a water reservoir tank 116. The top perimeter of the bowel 108 is defined by bowel rim 120. Typically, rim 120 has generally vertical and parallel inner and outer surfaces, and a horizontal top surface. The top surface of rim 120 is generally parallel to the bathroom floor 124. A toilet rim 120 provides a convenient support anchor that may be characterized as an upstanding wall or pillar.

(11) Table assembly 100 includes a table 140, a table leg generally indicated at 144, and a J-bracket generally indicated at 148. J-bracket 148 resembles an upside-down letter “J”, and is configured to couple with the rim 120. J-bracket 148 includes inner bracket leg 152, a horizontal shelf 156, and outer bracket leg 160. The bracket legs 152, 160 extend downwardly from cantilevered attachment at opposite ends of the shelf 156. The shelf 156 provides a load-bearing surface of a socket floor that is configured to rest on the top surface of rim 120. As illustrated in FIG. 1, the floor is disposed in a plane that is vertically offset from depending ends of the inner and outer legs 152, 160.

(12) A clamp mechanism, generally indicated at 164, may be included to enhance a connection between J-bracket 148 and rim 120. The illustrated clamp mechanism 164 includes a rotatable member 168 affixed to one end of a threaded shaft 172. The shaft 172 extends through a threaded opening in outer depending bracket leg 160 and terminates at clamp foot 176. Consequently, rotation of member 168 causes foot 176 to either move toward or away from the inner depending bracket leg 152, depending on direction of rotation. Rotation of member 168 in a tightening direction causes bowl rim 120 to be squeezed between inner bracket leg 152 and clamp foot 176. A line of action of a force applied by inner bracket leg 152 onto rim 120 is indicated by arrow-headed line 178.

(13) Many alternative workable clamp arrangements 164 may be envisioned. For example, it is within contemplation that a clamp mechanism 164 may cause a distance between the legs 152, 160 to be a controllable variable. In that case, the outer bracket leg 160 may directly contact the outer sidewall of bowl rim 120, and the rim 120 can be squeezed between the bracket legs 152, 160.

(14) It is within contemplation that a brace member may be included to brace against the bowl's outer surface 180 at a location spaced apart from, and below, the rim 120. An exemplary force line of action for one such brace member is illustrated by centerline 184. A brace member may sometimes be variably extendable between bracket and toilet to conform to a variety of toilets having different shapes. A brace member may supplement or even replace a clamp mechanism 164.

(15) The proximal table leg end 192 may be coupled to the outer bracket leg 160 by way of a coupling mechanism, generally indicated at 196. Certain coupling mechanisms 196 may permit assembly at a user's location. Such an arrangement permits a reduction in the shipping volume of a partially-assembled assembly 100. It is currently preferred that the table leg 144 is coupled to the J-bracket 148 at an angle to dispose a distal table leg end, generally 198, at a higher elevation than proximal table leg end 192. However, it is within contemplation that an assembly 100 may alternatively be configured with a vertical table leg 144.

(16) Illustrated coupling mechanism 196 includes a rectangular socket 200 in which to receive the free end of bracket leg 160. As also illustrated, a gusset 202 may be included to increase strength of the connection between the J-bracket 148 and table leg 144. The bracket leg 160 may be retained inside the socket 200 by a clamping element, such as one or more bolt 204. Sometimes, a clamping mechanism 196 may provide a vertical adjustment capability 208 to refine the elevation of an installed table 140 with respect to, e.g., the toilet rim 120. For example, the outer bracket leg 160 may be held at a selected one of a plurality of depths of insertion into socket 200.

(17) It is currently preferred that table leg 144 is adjustable in length. The illustrated table leg 144 is configured for telescopic reciprocation along telescopic length axis 216. Rod 220 is closely received for sliding inside tube 224. A holding mechanism, generally indicated at 228, can be adjusted to maintain rod 220 at a desired position with respect to tube 224. The exemplary holding mechanism 228 includes a clamping element, such as illustrated machine bolt 232. Bolt 232 engages a threaded portion of tube 224 to permit the free end of the rotated bolt to press onto the rod 228 and create a friction clamp between the rod and tube.

(18) An anti-twist mechanism, generally indicated at 240, may be included in certain embodiments 100. A workable anti-twist mechanism 240 includes slot 244 disposed in rod 220. Slot 244 is elongate in the telescopic length direction and receives the free end of bolt 232. The bolt 232 causes a structural interference with walls of the slot 244 to resist relative rotation WT between the rod 220 and tube 224 and about telescopic length axis 216.

(19) An alternative anti-twist mechanism 240 may be provided by the inherent interference between non-round cross-sections of certain cooperating rods and tubes. For example, close fitting rods and tubes having rectangular cross-sections would inherently resist relative rotation WT.

(20) Certain embodiments 100 may include an anti-roll mechanism, generally indicated at 260. A workable mechanism 260 may be operated to maintain the table 140 at a desired horizontal orientation. Illustrated anti-roll mechanism 260 includes a machine bolt 264 to affix the table 140 at the distal table leg end 198. Tightening the bolt 264 is operable to resist table rotation TR about a roll axis defined by the centerline of bolt 264.

(21) An exemplary brace member to enhance a table's anchor is generally indicated at 280 in FIG. 8. Brace member 280 includes a pair of threaded shafts 171 that are rotatable coupled to foot 176′. A workable shaft 272 includes a machine bolt received to slide in an aperture through the J-bracket 148. An extended shaft length between the surface 180 and the J-bracket 148 may be adjusted with jam nuts 284. Modified gusset 202′ includes a central aperture to generally align shafts 272 in the plane of table support load. It is within contemplation to include a resilient surface, such as rubber, as the contact surface between foot 176′ and outer surface 180.

(22) While aspects of the invention have been described in particular with reference to certain illustrated embodiments, such is not intended to limit the scope of the invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered as illustrative and not restrictive. Obvious changes within the capability of one of ordinary skill are encompassed within the present invention. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
