Customizable Shower Caddy

FIELD

The subject matter relates to organizational units and, more particularly, to vertical standing organizational units.

BACKGROUND

Shower caddies are often used in showers to provide organized shelving for personal hygiene products, such as shampoo, conditioner and soap. Common shower caddies include a rod or rods that extend from the shower basin to the ceiling and are fixed in position by applying pressure on the basin and the ceiling. The rods support shelves along their extent. The shelving is used to support personal hygiene products for easy access.

One known shortcoming of common shower caddies is that they are not adjustable such that they can be placed in either a corner, along a side wall, or in the center of the shower enclosure. Another known shortcoming is that the shelves tend to slide down the rods and their position along the rods needs to be reset. As a result, the amount of weight the shelves are able to hold is limited without increasing the tendency of the shelves to slide down the rods.

DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, there is illustrated a customizable shower caddy 10. The caddy 10, for example, is adjustable so it can stand along a side wall 12 (FIG. 1) of a shower enclosure 14 or in a corner 16 (FIG. 2) of the shower enclosure 14. The shower caddy 10 also can be adjusted to stand in the center of a shower enclosure 14.

The shower caddy includes a main rod 18, a secondary rod 20 and an optional secondary rod 22. The assembled rods 18, 20 (and optionally rod 22) include a bottom end cap 24 and a top end cap 26 that engage a shower basin 28 and a ceiling 30, respectively. Barrels 32 are adjustable along the rods 18, 20 (and optionally rod 22) to a preferred height. The barrels 32 support baskets 34 and shelves 36. The caddy 10 is more stable due to fewer rod sections when compared to other caddies. The barrels 32 provided enhanced gripping so that the baskets 34 and shelves 36 may support more weight than other caddies. The rods 18, 20 and 22 may be made of metal, such as steel or aluminum. The baskets 34 and shelves 36 may be made of metal, such as aluminum.

Turning to FIGS. 3-5B, the main rod 18 is fitted at one end with an insert 38 and at the other end with a rod collar 40. The insert 38 and the rod collar 40 are press fitted into the main rod 18. The insert 38 cooperates with the bottom end cap 24 for adjustment. The rod collar 40 seals an annular gap between the main rod 18 and the secondary rod 20. By way of example only, the main rod 18 may have a length of 52 inches and a diameter of 1 inch.

The insert 38 is generally cylindrical in shape and includes a ribbed portion 42 for insertion into the main rod 18 and a threaded portion 44 that threads into the bottom end cap 24. The ribbed portion 42 includes longitudinally extending ribs 46 equally spaced from one another. As illustrated, there may be six ribs. The ribs 46 engage an inner sidewall of the main rod 18 to provide a friction fit with the main rod 18. A terminal end 48 of the ribbed portion 42 includes an annular chamfer 50 to assist in the insertion process. The threaded portion 44 includes right-hand threading 52. The ribbed portion 42 and the threaded portion 44 are separated by an annular flange 54 that engages the end of the main rod 18 to limit insertion into the main rod 18 to only the length of the ribbed portion 42. By way of example only, the insert 38 may have a length of 1.654 inches, the flange 54 may have an outer diameter of 1.010 inches, and the threading 52 may have an outer diameter of 0.830 inches.

The rod collar 40 has a generally cylindrical shape with a tubular body 56 and a terminal end 58 with an annular chamfer 60 and a step 62 that extends radially outward. The step 62 stops insertion of the rod collar 40 into the main rod 18 when the main rod 18 abuts step 62. By way of example only, the step 62 may have an outer diameter of 1.0 inches, the tubular body 56 may have an outer diameter of 0.875 inches, and annular chamfer 60 may have a longitudinal length of 0.220 inches. The collar 40 may be made of plastic, such as polyproplylene.

With reference to FIGS. 6A-8B, the bottom end cap 24 has a bell-shaped body 64 with an upper portion 66 and a bottom portion 68. An internal flange 70 includes internal threading 72 that mates with the external threading 52 of the insert 38 so that the main rod 18 and the bottom end cap 24 can be adjusted relative to one another. The adjustment may be used to put pressure on the shower basin 28 during installation of the shower caddy 10 or to release pressure on the shower basin 28 to uninstall the shower caddy 10. The upper portion 66 defines a cylindrical passage 74 that receives the end of the main rod 18 that is fitted with the insert 38 with a slight clearance to allow rotation of the main rod 18 relative to the bottom end cap 24.

A terminal end 76 of the bottom end cap 24 defines a recess 78. The recess 78 may receive a rubber pad or the terminal end 76 may fit into a rubber pad 80. The rubber pad 80 provides increased frictional engagement with the shower basin 28 to limit or prevent the shower caddy 10 from walking and/or sliding on the shower basin 28 during installation and provides a secure installation. The rubber pad 80 can be glued to the terminal end 76. A bottom 81 of the rubber pad 80 includes radially extending channels 83 to enable water and/or air to escape during the installation process and after being installed. A top 85 of the rubber pad 80 includes a circular recess 87 that receives the terminal end 76 of the bottom end cap 24. By way of example only, the rubber pad 80 may be 2.240 inches in diameter, the circular recess 87 may be 2.00 inches in diameter, and the thickness of the rubber pad 80 may be 0.275 inches.

An end cap seal 90 seals the clearance between the main rod 18 and the upper portion 66. The end cap seal 90 includes a cylindrical body 92 defining a central passage 94 and a terminal end 96 with a chamfer 98 and a step 100. The step 100 stops insertion of the seal 90 into the body 64 of the bottom end cap 24 when step 100 abuts the end the upper portion 66. By way of example only, the end cap seal 90 may have a height of 0.407 inches and an inner diameter of 1.0 inch. The chamfer 98 at the step 100 may have a diameter of 1.291 inches.

With reference to FIGS. 9A-9I, there is illustrated a lock assembly 102 to lock the position of the main rod 18 and the secondary rod 20 relative to one another at a desired combined length. For example, the secondary rod 20 is extended from the main rod 18 until the desired overall length is achieved, and then, the lock assembly 102 is activated to secure the main rod 18 and the secondary rod 20 together against any further longitudinal movement relative to one another.

The lock assembly 102 includes a lock ramp 104, a secondary rod insert 106, and a lock sleeve 108. The lock ramp 104 and the secondary rod insert 106 may be molded from any rigid material, including a rigid plastic material. The lock sleeve 108 also may be molded from any rigid material, including plastic, but must be flexible enough to expand as it moves along the lock ramp 104 and provide a sufficient frictional engagement with an inner surface of the main rod 18 to secure the rods 18, 20 against relative movement.

The lock ramp 104 includes a frusto-conical wedge portion 110 at one end and a threaded portion 112 with a right-hand thread 114. The wedge portion 110 includes a groove 116 extending longitudinally along the length of the wedge portion 110. A head 118 is at the other end of the lock ramp 104 and includes a stop 120 (see FIG. 9D) at the other end. The longitudinal groove 116 guides longitudinal movement of the lock sleeve 108 along the wedge portion 110. The stop 120 prevents rotation of the insert 106 relative to the threaded portion 112 of the lock ramp 104 so that the insert 106 does not overtighten against the head 118.

The secondary rod insert 106 has a generally hollow cylindrical shape and includes a male component 122 and a female component 124. When the male component 122 and the female component 124 are mated to form the insert 106, the components 122, 124 define a passage 126 through the insert 106. The insert 106 fits with a friction fit in one end of the secondary rod 20 (see, e.g., FIG. 9A). The insert 106 can further be captivated in the secondary rod 20 by one or more notches or detents formed in the inside wall of the secondary rod that penetrate the outer surface of the insert 106. The engagement between the insert 106 and the secondary rod 20 prevents rotation of the insert 106 relative to the secondary rod 20.

The male component 122 includes protrusions 128, a first circumferential flange 130, a second circumferential flange 132, an annular groove 134 formed between the first circumferential flange 130 and the second circumferential flange 132, a threaded portion 136 having left hand threads 138, and exterior longitudinally extending ribs 140, which aid in providing better friction fit between the insert 106 and the secondary rod 20.

The female component 124 includes recesses 142, a first circumferential flange 144, a second circumferential flange 146, an annular groove 148, a threaded portion 150, having left hand threads 152, exterior longitudinally extending ribs 154, which provide a friction fit between the insert 106 and the secondary rod 20, and a stop 156, which engages the stop 120 of the lock ramp 104 upon unlocking the lock assembly 102.

The recesses 142 of the female component 124 receive the protrusions 128 of the male component 122, such that the components 122, 124 may be combined to form the insert 106. The protrusions 128 may have a friction fit in the recesses 142 or may be glued or welded in the recesses 142. While four are shown, there may be less or additional protrusions 128 and recesses 142.

The second circumferential flanges 132, 146 combine to form a single annular flange that extends about a perimeter of one end of the insert 106 for engaging an end of the secondary rod 20, such as a bottom end 158 of the secondary rod 20 (see FIG. 9A) to prevent complete insertion therein. The left-hand threads 138, 152 combine to form a single thread, such that turning the insert 106 toward the user locks the assembly 102 and turning the insert 106 away from the user unlocks the assembly 102. The thread 114 of the threaded portion 112 of the lock ramp 102 meshes with the combined threads 138, 152 of the insert 106.

The first circumferential flanges 130, 144 combine to form a single annular flange. The lock sleeve 108 includes an annular groove 160 that receives the annular flange formed by the first circumferential flanges 130, 144 of the insert 106. The lock sleeve 108 includes an interior flange 162 which is received in a single annular groove formed by the annular grooves 134, 148 of the insert 106, thus connecting the insert 106 and the lock sleeve 108. As the threaded portion 112 of the lock ramp 104 is turned into the insert 106, the insert 106 moves closer to the wedge portion 110 of the lock ramp 104. This causes the lock sleeve 108 to move along the wedge portion 110, causing the lock sleeve to expand and thereby lock the rods 18, 20 against movement relative to one another. The expansion of the lock sleeve 108 is not to an extent that would cause the attachment between the lock sleeve 108 and the insert 106 to become disconnected.

The lock sleeve 108 has an elongated slot 164 along its entire axial length to form a split configuration. This enables the lock sleeve 108 to be expanded from a first state that allows relative movement of the rods 18, 20 to a second state to lock the rods 1, 20 against relative movement. The lock sleeve 108 includes a longitudinally extending rib 166 on its interior that is offset 180 degrees from the slot 164. The lock sleeve 108 receives the wedge portion 110 of the lock ramp 104 with the rib 166 in the groove 116 of the lock ramp 104.

The stop 156 is on the portion of the insert 106 facing the head 118 of the lock ramp 104. The stop 156 is configured as a ramp with a stepped surface 168 and a ramped surface 170. The stop 120 is on the head 118 of the lock ramp 104 at the end of the threaded portion 112. More specifically, the stop 120 is formed by a radial flange 172 about a portion of the head 118. The radial flange 172 may extend about 180 degrees around the head 118.

The insert 106 and the threaded portion 112 of the lock ramp 104 reside in the secondary rod 20, and when locking the main rod 18 and the secondary rod 20, the stop 156 of the insert 106 disengages the stop 120 of the lock ramp 104. If the locking assembly 102 is in the fully unlocked position, the radial flange 172 may slide along the ramped surface 170 during the first and/or additional twists of the threaded portion 112 in the locking direction so that the flange 172 does not get caught on the stop 156 as the stop 120 rotates away from the stop 156.

When the user loosens the main rod 18 and the secondary rod 20 by rotating the secondary rod 20 counterclockwise thereby operating the threads 138, 152 of the insert 106, the stop 156 of the insert 106 moves toward the head 118 of the lock ramp 104. The insert 106 rotates until the stop 156 engages the stop 120 of the head 118. The stops 120, 156 are rigid and prohibit further rotation of the insert 106 and the lock ramp 104 relative to one another. The relative circumferential location of the stop 120 and the lock ramp 104 may be positioned to leave a small gap 174 between the insert 106 and the head 118 when the insert 106 is rotated to its fully unlocked position. This ensures that the insert 106 and head 118 will not become stuck together and may resist or even prevent rotation in the locking direction.

Additional details of the lock assembly 102 are contained in U.S. application Ser. No. 16/297,357, filed Mar. 8, 2019, which is incorporated herein by reference in its entirety.

As shown in FIGS. 10-16, there is illustrated an alternative lock assembly 180 interconnecting the main rod 18 and the secondary rod 20. The lock assembly 180 includes a wedge shaft 182, a rod insert 184 and a wedge 186. The rod insert 184 is attached to the secondary rod 20 and extends into the main rod 18. Dimples 188 formed in the secondary rod 20 can bite into the rod insert 184 to hold the rod insert 184 against longitudinal and rotational movement relative to the secondary rod 20. The wedge 186 is positioned in the main rod 18, and the wedge shaft 186 operatively interconnects the rod insert 184 and the wedge 186.

To secure the lock assembly 180, the main and secondary rods 18, 20 may be turned in opposite directions which causes the wedge 186 to be tightly seated between the main rod 18 and the rod insert 184. In situations where the bottom and top end caps 24, 26 are adjustable, additional inward force on the main and secondary outer rods 18, 20 caused by the end caps 24, 26 during their adjustment can cause the main and secondary rods 18, 20 to inadvertently adjust relative to one another. FIG. 10 shows the lock assembly 180 in an unlocked state, and FIG. 11 shows the lock assembly 180 in a locked state. With reference to FIG. 11, the lock assembly 180 provides an adjustment gap 190 that enables the lock assembly 180 to tighten even further when the end caps 24, 26 are adjusted. The adjustment gap 190 allows the wedge 186 to move further towards the rod insert 184 to provide an even tighter seating of the wedge 186 between the main rod 18 and the rod insert 184 to prevent unintentional shifting of the main and secondary rods 18, 20 relative to one another.

As shown in FIG. 13, the wedge shaft 182 includes a stepped head portion 192, a shaft 194 and threading 196 along at least a portion of the shaft 194. The stepped head portion 192 includes a terminal disc end 198 that rotates in the wedge 186. Immediately inward of the terminal disc end 198 is an annular flange 200 that moves the wedge 186 between the locked state and unlocked states (FIGS. 10 and 11). The flange 200 includes an axially extending slot 202.

With reference to FIGS. 14A-C, the rod insert 184 may be a two part component with a first component 204 and a second component 206. The two components 204, 206 are mirror images of one another except that the first component 204 may include a number of pegs 208 and the second component 206 may include a number of complimentary sockets 210 for receiving the pegs 208 to align the components 204, 206. The rod insert 184 defines an internal passage 212 with a smooth portion 214 and a threaded portion 216.

The wedge shaft 182 extends through the internal passage 212, and the threading 196 of the wedge shaft 182 engages with the threaded portion 216 of the rod insert 204. An outer surface 218 of the threaded portion 216 is cylindrical, and the outer surface 220 of the smooth portion 214 is conical. An annular step 222 transitions the cylindrical outer surface 218 with the conical outer surface 220. The step 222 engages an end of the secondary rod 20 to limit insertion of the rod insert 204 into the secondary rod 20 beyond the cylindrical outer surface 218.

As shown in FIGS. 15 and 16, the wedge 186 has a split configuration with an axially extending gap 224 and a conical inner surface 236 and a cylindrical outer surface 238. The wedge 186 defines a longitudinally extending passage 228 with an annular stop 230 at on end. Immediately adjacent the annular stop is an annular recess 232 that is intersected by an axially extending rib 234. Then, just inward of the annular recess 232 is an annular conical surface 236. The annular conical surface 236 slides against the outer conical surface 220 of the rod insert 184 when moving the wedge 186 between the locked and unlocked states.

The adjustment gap 190 of the lock assembly 180 is formed because the longitudinal length of the annular recess 232 of the wedge 186 is slightly larger than the thickness of the annular flange 200 of the wedge shaft 182. In one embodiment, the longitudinal length of the annular recess 232 may be 0.350 inches, and the thickness of the annular flange 200 may be 0.254 inches, creating an adjustment gap 190 of 0.096 inches. Overall, the adjustment gap 190 allows the compressive force to further move the rod insert 184 and the wedge 186 towards one another to increase the locking force of the lock assembly 180. This prevents the rods 18, 20 from unintentionally slipping relative to one another. This assists users that may not be strong enough to initially set the lock assembly 180.

More specifically, to set the lock assembly 180, the rods 18, 20 are pulled apart to set the desired length. Once the length is set, at least one of the rods 18, 20 is turned relative to the other to activate the lock assembly 180. For instance, the main rod 18 can be held stationary in one's left hand, while the secondary rod 20 can be turned with one's right hand towards the user's body. This causes the rod insert 184 to move closer towards the wedge 186 which prevents the wedge 186 from rotating because an outer surface 238 of the wedge 186 has a friction engagement with an inner surface 240 of the main rod 18. Alternatively, instead of holding the main rod 18 stationary, it also can be turned with one's left hand away from one's body simultaneously with turning the secondary rod 20. In either case, this will cause the rod insert 184 to turn and the threading 196 on the wedge shaft 182 to engage the threaded portion 216 of the rod insert 184. This, in turn, will cause the annular flange 200 of the wedge shaft 182 to shift to the inner side of the annular recess 232 to draw the wedge 186 toward the rod insert 184. The annular conical surface 236 of the wedge 186 will ride along the conical outer surface 220 of the rod insert 184. This forces the wedge 186 to lodge with a tight friction fit between the main rod 18 and the rod insert 184 to prevent the rods 18, 20 from moving relative to one another. The longitudinally extending gap 224 along the wedge 186 will widen as the wedge 186 moves along the rod insert 184.

The adjustment gap 190 will allow the use of adjustable end cap systems, such as assemblies 24, 26, to further drive the wedge 186 onto the conical outer surface 220 of the rod insert 184 to provide further locking force. More specifically, as the adjustable end assemblies 24, 26 are activated by turning the rods 18, 20 together in the same direction, such as towards the user, the end assemblies 24, 26 extend from the rods 18, 20 and will apply a compressive force on the rods 18, 20. This compressive force will cause the wedge 186 to automatically shift further along the conical outer surface 220 of the rod insert 184 to lodge even further between the main rod 18 and the rod insert 184 to provide an even tighter friction fit between the main rod 18 and the rod insert 184 to prevent the rods 18, 20 from moving relative to one another.

The rib 234 of the wedge 186 sits in the longitudinally extending gap 202 of the annular flange 200 of the wedge shaft 182. This keys the wedge shaft 182 to the wedge 186 to prevent rotational movement between the two.

To undo the locking assembly 180, the rods 18, 20 are turned in the direction opposite to the locking directions. In this operation, the annular flange 200 of the wedge shaft 182 engages the annular stop 230 at the other side of the annular recess 232 of the wedge 186 and drives the wedge 186 down the conical outer surface 220 of the rod insert 184.

Additional details of the lock assembly 180 are contained in U.S. Application No. 62/880,483, filed Jul. 30, 2019, which is incorporated herein by reference in its entirety.

Referring to FIGS. 9A and 17, an end of the secondary rod 20 opposite the lock assembly 106 (or 180) is fitted with a connection insert 242. The connection insert 242 attaches to the top end cap 26 or the optional extension rod 22 (discussed later). The connection insert 242 includes an insert portion 246 and a threaded portion 248. A terminal end 250 of the insert potion 246 is chamfered to aid with insertion into the secondary rod 20. The insert portion 246 includes longitudinally extending ribs 252 that engage an inside surface 254 of the secondary rod 20 with a friction fit that prevents rotation of the connection insert 242 relative to the secondary rod 20 and unintentional removal of the connection insert 242 from the secondary rod 20. The threaded portion 248 includes a left-hand thread 256. A stop flange 258 disposed between the insert portion 246 and the threaded portion 248 engages the end of the secondary rod 20 to prevent insertion of the connection insert 242 beyond the insert portion 246.

By way of example only, the secondary rod 20 may have a length of 52 inches and an outer diameter of 0.875 inches. The outside diameter of the threaded portion 248 of the connection insert 242 may be 0.875 inches.

With reference to FIGS. 18A-B, the top end cap 26 has a bell-shaped body 260 with an upper portion 262 and a lower portion 264 defining a hollow interior 265. An internal flange 266 includes internal threading 268 that mates with the external threading 256 of the connection insert 242 so that the secondary rod 20 (or the optional extension rod 22) and the top end cap 26 can be adjusted relative to one another. The adjustment can be used to apply pressure on the ceiling 30 to install the shower caddy 10 or release pressure on the ceiling 30 to uninstall the shower caddy 10. The lower portion 264 defines a cylindrical passage 270 that receives the end of the secondary rod 20 (or the optional extension rod 22) that is fitted with the connection insert 242 with a slight clearance to allow rotation of the secondary rod 20 (or the optional extension rod 22) relative to the top end cap 26. By way of example only, the top end cap 26 may have a length of 2.479 inches and a maximum diameter of 2.0 inches.

A terminal end 272 of the top end cap 26 defines a recess 274. The recess 274 receives a rubber pad or fits into the rubber pad 80 to provide increased frictional engagement with the ceiling 30. This aids to prevent the shower caddy 10 from walking and/or sliding on the ceiling 30 of the shower caddy 10 during installation and provides a secure installation. The rubber pad 80 may have the same structure as and be secured to the end cap 26 as the rubber pad 80 described above.

An end cap seal, such as end cap seal 90, may be fitted into the clearance between the secondary rod 20 (or the extension rod 22). The end cap seal 90 is not required at either the bottom end cap 24 or the top end cap 26 but can be used at either or both.

As show in FIG. 19, ends of the optional extension rod 22 are fitted with the connection insert 242 and an extension rod insert 276. The connection inert 242 is the same as that described above and will not be described here again. The connection insert 242 fitted into the end of the optional extension rod 22 will mate with the top end cap 26. The extension rod insert 276 is designed to mate with the connection insert 242 fitted into the end of the secondary rod 20.

With reference to FIGS. 20A-C, the extension rod insert 276 includes an insert portion 278 and a socket portion 280. The insert portion 278 includes a terminal end 282 with a chamfer to aid in inserting the extension rod insert 276 into the end of the extension rod 22. The insert portion 278 includes a cylindrical outer surface 283 with longitudinal ribs 284 extending from the outer surface 283. The ribs 284 engage the inner surface of the extension rod 22 with a friction fit to prevent unintentional removal of the insert 276 from the extension rod 22 and unintentional rotation of the insert 276 relative to the extension rod 22. An annular external step 286 is at the transition between the insert portion 278 and the socket portion 280. The step 286 engages the end of the extension rod 22 to prevent insertion of the insert 276 into the end of the extension rod 22 beyond the insert portion 278.

The socket portion 280 includes internal threads 288 that mate with the external threads 256 of the connection insert 242 this is fitted into the end of the secondary rod 20. The socket portion 280 further includes an annular internal stop 290 that engages the stop flange 258 of the connection insert 242 to prevent over insertion of the threaded portion 248 of the connection insert 242 into the socket portion 280.

By way of example only, the length of the extension rod insert 276 may be 2.087 inches, the length of the socket portion 280 may be 1.337 inches, the outer diameter of the socket portion 280 may be 1.022 inches, and the inner diameter of the socket portion 280 may be 0.866 inches.

Turning to FIGS. 21A-21L, the barrels 32 each include a barrel body 292 with a top end portion 294 and a bottom end portion 296. The outside of the barrel body may have an hour-glass profile 298 or any other profile, such as a rectangular or cylindrical. The inside of the barrel body has a generally cylindrical profile 300.

The top end portion 294 includes an inner annular smooth portion 306, an interrupted threaded portion 308 and an annular landing 310 at the base of the interrupted threaded portion 308. The interrupted threaded portion 308 may include four arcuate projections 316 with external threads that form a threading for a top cap 318. The end portion 294 includes arcuate ledges 320 between the arcuate projections 316. A recess 322 defined by the end portion 294 extends longitudinally inward from each ledge 320. The ledges 320 and recesses 322 are used in mounting the baskets 34 and shelves 36. Thus, the illustrated barrel 32 can support up to four baskets 34 and/or shelves 36. The barrel can be scaled to support additional or less baskets and/or shelves. The bottom end portion 296 includes internal threading 324 that is used to mount a bottom cap 326.

By way of example only, the barrel body 292 may have a combined length of 3.282 inches. The maximum outer diameter of the insert 302 may be 1.46 inches.

The top cap 318 includes an annular sidewall 328 defining longitudinal channels 330 on the outside for gripping and turning the top cap 318. The inside of the sidewall defines internal threading 332 that cooperates with the threading on the arcuated threaded projections 316 to mount the top cap 318 and the barrel body 292. The top cap 318 also includes a top portion 334 extending from the annular sidewall 328 and an annular bead 336 about its terminal end.

By way of example only, the top cap 318 may have a maximum height of 0.760 inches and a maximum diameter at the annular bead 336 of 1.54 inches.

The bottom cap 326 includes an annular sidewall 337 with an externally threaded portion 338 that cooperates with the internal threads 324 of the barrel body 292 to mount the bottom cap 326 to the barrel body 292. The sidewall 337 also defines longitudinal channels 340 on the outside for gripping and turning the bottom cap 326. The bottom cap 326 also includes a top portion 342 extending from the annular sidewall 337. An annular bead 344 extends from the side wall 337 at a transition between the externally threaded portion 338 and the longitudinal channels 340. The inside of bottom cap 326 includes a cylindrical segment 346 and a conical segment 348.

By way of example only, the bottom cap 326 may have a maximum length of 1.102 inches and a maximum outer diameter at the annular bead 344 of 1.524 inches. The externally threaded portion 338 may have a length of 0.392 inches measured from the annular bead 344. The cylindrical segment may have a diameter of 1.025 inches. The conical segment 348 may have an outward taper angle of 20.1 degrees and a maximum diameter of 1.146 inches at a terminal end.

Each barrel 32 is used with either a large wedge insert 350 or a small wedge insert 352. The large wedge insert 350 is used to mount the barrel 32 to the main rod 18, and the small wedge insert 352 is used to mount the barrel 32 to the secondary rod 20 or the optional rod 22. The wedge inserts 350, 352 are disposed in a conical section 297 of the bottom end portion 296 of the barrel body 292 and the conical segment 348 of the bottom cap 326. As the bottom cap 326 is threaded onto the barrel body 292, the wedge inserts 350, 352 apply pressure to the main rod 18 or the secondary or optional rods 20, 22 to lock the barrel 32 in a desired position along the rods 18, 20, 22.

The large wedge insert 350 includes an annular ring 354. The ring 354 includes two ends 356 that define a gap 358 therebetween. The gap 358 allows the ring 354 to be tightened onto the main rod 18. An inner surface 360 of the ring 354 is cylindrical, and an outer surface 362 forms a taper from a center apex 364 to terminal edges 366. By way of example only, the large wedge insert 350 may have a height of 0.400 inches, an inner diameter of 0.5 inches and a maximum outer diameter of 0.580 at the apex 364. The angle of taper for the outer surface 362 extending from the apex 364 to the terminal edges 366 may be 20.1 degrees. The wedge insert 350 may be made of nylon.

The small wedge insert 352 includes an annular ring 368. The ring 368 includes two ends 370 that define a gap 372 therebetween. The gap 372 allows the ring 368 to be tightened onto the secondary rod 20 or the optional rod 22. An inner surface 360 of the ring 354 is formed with arcuate teeth 374 that extend radially inward. The teeth 374 can bite into the secondary rod 20 or the optional rod 22 to lock the barrel 32 in place. An outer surface 376 of the ring 368 forms a taper from a center apex 378 to terminal edges 380.

By way of example only, the small wedge insert 352 may have a height of 0.400 inches, an inner radius of 0.438 inches at the teeth 374, an inner radius of 0.500 in between the teeth 374, and an outer maximum radius of 0.580 at the apex 378. The angle of taper for the outer surface 376 extending from the apex 378 to the terminal edges 380 may be 20.1 degrees. The wedge insert 352 may be made of nylon.

Turning to FIGS. 22A and 22B, there is illustrated the main rod 18 with two barrels 32, one holding a pair of baskets 34 and the other holding a pair of shelves 36. Each basket 34 includes an upper frame 382 and a lower frame 384. The frames 382, 384 are spaced from one another and interconnected to each other by a barrel frame support 386 and an end frame support 388. The barrel frame support 386 mounts the basket 34 to the barrel 32 as discussed further below. A large tray 390 may be by the lower frame member 384 and/or the upper frame 382, and a razor hanger 392 is suspended from the upper frame 382.

The shelves 36 each include a frame 394, a barrel support 396 and an arcuate frame support 398. The barrel support 396 mounts the frame 394 to the barrel 32. The arcuate frame 398 interconnects the frame 394 with the barrel support 396. The single frame 394 may support the large tray 390, another tray 391 or a small tray 400. The small tray 400 also may be supported by the upper frame 382 or the lower frame 384 of the basket 36.

With reference to FIGS. 23A-D, the upper frame 382 and the lower frame 384 are identical. The frames 382, 384 include a pair of opposed side members 402 interconnected by an end member 404. The other end of the side members include angled members 406 that from a gap 408 therebetween. The end member 404 defines a pair of holes 410 for mounting to the end frame support 388. The angled members includes a pair of holes 412 for mounting to the barrel frame support 386. The frame of the shelf 36 can have the same structure as the frames 382, 384 of the basket 34.

By way of example only, the frames 382, 384 may have a length of 7.583 inches, a width of 3.90 inches, a height of 0.400 inches. The material for the frames 382, 384 may be aluminum with a thickness of 0.075 inches.

The holes 420 are spaced and the wings 414, 416 and are angled so that the holes 420 align with the holes 412 of the angled members 406 of the upper and lower frames 382, 384. Fasteners are used to connect the barrel frame support 386 to the frames 382, 384 using the holes 412, 420. The fasteners may be rivets. The wings 414, 416 include a lower ledge 424 for the frames 382, 384, 394 to sit on when mounted to the barrel frame support 386. The ledges 424 provide support for the frames 382, 384, 394. Further, the upper wings 414 may include an upper ledge 426 that forms a channel 428 with the lower ledge 424.

The hook 422 includes a lateral member 430 and a longitudinal member 432. When engaged with the barrel body 292, the lateral member 430 rests on the arcuate ledge 320, and the longitudinal member 432 inserts into the recess 322. The hook 422 enables the barrel frame support 386 to hang from the barrel 32 to support the basket 34 or shelf 36. The spacer 418 includes an outer surface 434 that engages the hour-glass profile 298 of the barrel body 292 when the barrel frame support 386 is mounted to the barrel 32. The channel 436 is formed by the spacer 418 and the lateral member 430 and the longitudinal member 432 of the hook 422. The top cap 318 may be screwed on to the barrel body 292 to trap the hook between the top cap 318 and the barrel body 292 so that the hook 422 cannot be unintentionally removed from the barrel body 292.

By way of example only, the barrel frame support 386 may have a height of 3.47 inches and wingspan of 2.7 inches at each pair of wings 414, 416. The wings may be angled at 90 degrees to one another.
