However, a reverse arrangement is provided on the second rack 104. Particularly, the first hoop 164 of the second rack 104 is offset inwardly from the first side portion 156 a greater distance than an offset of the second hoop 166 from the second side portion 158. With this spatial arrangement of the respective first and second hoops of the first and second racks 102, 104, in the assembled condition of the drying rack 100, the first hoop 144 of the first rack 102 is outward and adjacent to the first hoop 164 of the second rack 104 and the second hoop 166 of the second rack 104 is outward and adjacent to the second hoop 146 of the first rack 102.
With reference to FIGS. 4 and 7, the movable core member 110 of the hinge assembly 106 includes a body 190 having a base wall 192, first and second side walls 194, 196 depending from the base wall 192, and first and second end walls 198, 200 also depending from the base wall 192. Opposite end portions 206, 208 of the base wall 192 extend outwardly past the first and second end walls 198, 200 and can be canted downwardly toward the core member housing 112. A first tab 210 extends from a lower surface of the base wall 192 and is outwardly adjacent of the first end wall 198. The first tab 210 is provided with a step 212 that defines a ledge 214 extending in a direction transverse to a length direction of the movable core member 110. The step 212 separates the first tab 210 into a first section 216 and a second section 218 which is offset outwardly from the first section. Similarly, a second tab 220 extends from the lower surface of the base wall 192 and is outwardly adjacent of the second end wall 200. The second tab 220 is provided with a step 222 that defines a ledge 224 extending in a direction transverse to the length direction of the movable core member 110. The step 222 separates the second tab 220 into a first section 226 and a second section 228 which is offset outwardly from the first section. As best shown in FIG. 8, the second section 228 of the second tab 220 is opposite to the second section 218 of the first tab 210.
Further, the body 190 of the movable core member 110 has defined therein first and second receptacles 240, 242 dimensioned to releasably secure therein the respective first and second cleaning devices 126, 128. The first and second receptacles 240, 242 are separated by their respective inner walls 246, 248, which are inwardly spaced from the first and second end walls 198, 200. A flange 250 extends about a periphery 252 of the base wall 192 of the body 190 and, as depicted in FIG. 7, is adapted to mate with the an edge surface 254 of the core member housing 112. According to one aspect, the movable core member 110 and the core member housing 112 can be formed as separate components of the hinge assembly 106 that can be assembled mechanically to one another. For example, in assembly the core member housing 112 can be welded or adhered to the movable core member 110. In the illustrated embodiment, the core member housing 112 is generally U-shaped in cross-section and includes an in outer surface 260 and an inner surface 262. The inner surface 262 is provided with first and second grooves 266, 268 dimensioned to receive the respective first and second tabs 210, 220 of the movable core member 110. It should be appreciated that the grooves 266, 268 ensure proper placement of the movable core member 110 within the core member housing 112 and provide a secure engagement between the movable core member 110 and the core member housing 112. According to another aspect, the movable core member 110 and the core member housing 112 of the hinge assembly 106 can be formed as a unitary component, for example, wherein the core member housing 112 is overmolded onto the movable core member 110. Feet 270, which can be formed of an elastomeric material, can be provided on the outer surface of the core member housing 112.
With reference now to FIGS. 4 and 8, each of the first and second plugs 120, 122 includes a respective cylindrical shaped body 280, 282 dimensioned to be received in the core member housing 112. The body 280 of the first plug 120 has a first end portion 286 and a second end portion 288. An enlarged head 290 is located at the first end portion 286 and defines a stop for the insertion of the first plug 120 into the core member housing 112. Located adjacent the head 290 is a radially extending projection 294 dimensioned to be received in a corresponding notch 296 located on an inner surface 298 of the first hoop 144 of the first rack (FIG. 5), and located inwardly of the projection 294 is an annular ring 302 dimensioned to be received in a corresponding annular groove 304 located on an inner surface 306 of the first hoop 164 of the second rack 104. The engagement between the projection 294 and the first hoop 114 ensures that the first plug 120 rotates together with the first rack 102, and the engagement between the ring 302 and the first hoop 164 prevents axial movement of the first plug 120 within the core member housing 112. The second end portion 288 of the body 280 of the first plug 120 includes a slot 310 extending at least partially about a circumference of the body 280. The slot 310 at least partially defines a resilient arm 312 at the second end portion 288, the arm 312 including an axially extending finger 314. It should be appreciated that rotation of the first plug 120 with the first rack 102 causes the finger 314 to contact the ledge 214 provided on the first tab 210 of the movable core member 110 at each of the closed and opened positions of the first rack 102, and the ledge serves as a stop for preventing over-rotation of the first rack 102 with respect to the movable core member 110. However, it should also be appreciated that if a user attempts to over-rotate the first rack 102 beyond its fully opened position, e.g., rotate the first rack 102 in an opening direction beyond the open use position of the drying rack 100 shown in FIG. 3, the flexing of the arm 312 allows the finger 314 to move slightly past the ledge 214 onto the second section 218 of the first tab 210, thereby preventing damage to the drying rack 100.
Similarly, and with continued reference to FIGS. 4 and 8, the body 282 of the second plug 122 has a first end portion 320 and a second end portion 322. An enlarged head 326 is located at the first end portion 320 and defines a stop for the insertion of the second plug 122 into the core member housing 112. Located adjacent the head 326 is a radially extending projection 330 dimensioned to be received in a corresponding notch 332 located on an inner surface 334 of the second hoop 166 of the second rack (FIG. 4), and located inwardly of the projection 330 is an annular ring 338 dimensioned to be received in a corresponding annular groove 340 located on an inner surface 342 of the second hoop 146 of the first rack 102 (FIG. 5). The engagement between the projection 330 and the second hoop 166 ensures that the second plug 122 rotates together with the second rack 104, and the engagement between the ring 338 and the second hoop 146 prevents axial movement of the second plug 122 within the core member housing 112. The second end portion 322 of the body 282 of the second plug 122 includes a slot 350 extending at least partially about a circumference of the body 282. The slot 350 at least partially defines a resilient arm 352 at the second end portion 322, the arm 352 including an axially extending finger 354. Rotation of the second plug 122 with the second rack 104 causes the finger 354 to contact the ledge 224 provided on the second tab 220 of the movable core member 110 at each of the closed and opened positions of the second rack 104, and the ledge serves as a stop for preventing over-rotation of the second rack 104. Again, it should also be appreciated that if a user attempts to over-rotate the second rack 104 beyond its fully opened position, e.g., rotate the second rack 104 in an opening direction beyond the open use position of the drying rack 100 shown in FIG. 3, the flexing of the arm 352 allows the finger 354 to move slightly past the ledge 224 onto the second section 228 of the second tab 220, thereby preventing damage to the drying rack 100.
With reference to FIGS. 3, 6 and 9, the first cleaning device 126 includes a handle 360 which can be defined by a core 362 and an elastomeric outer grip 364 which can be overmold onto the core 362. The handle 360 is dimensioned to be frictionally and releasably received in the first receptacle 240. A wire support 366 has one end portion secured in the core 362. According to one aspect, an elongated cylindrical shaped brush 370 is mounted to the other end portion of the wire support 366. The second cleaning device 128 includes a handle 380 which can be defined by a core 382 and an elastomeric outer grip 384 which can be overmold onto the core 382. The handle 380 is dimensioned to be frictionally and releasably received in the second receptacle 242. A wire support 386 has one end portion secured in the core 382. According to one aspect, an elongated generally triangular shaped brush 390 is mounted to the other end portion of the wire support 386. However, it should be appreciated that the second cleaning device 128 can have a brush similar to the first cleaning device 126.
As described above, the drying rack 100 includes a first rack 102 and a second rack 104 pivotally connected with the first rack 102. The movable core member 110 includes a receptacle (two receptacles 240, 242 are in the illustrated embodiment) each configured to receive an associated cleaning device, such as the cleaning devices 126, 128. The movable core member 110 is operatively connected for pivotal movement with and pivotal movement with respect to each rack 102, 104 so as to change a relative location of the receptacle 240, 242 with respect to at least one of the first rack 102 and the second rack 104 based on a relative position of the first rack 102 with respect to the second rack 104. This allows the cleaning devices 126, 128 to be presented in a vertical orientation when the drying rack 100 is in the open use position, which is shown in FIG. 3. This also allows for a horizontal orientation of the cleaning devices 126, 128, for example when the second rack 104 is brought toward the first rack 102 from the position shown in FIGS. 9 and 10 to the position shown in FIG. 11.
The drying rack 100 includes a contact element provided on or connected with the first rack 102. The contact element can be the finger 314 on the first plug 120, the finger 354 on the second plug 122, a section 402 of the first rack 102 adjacent the first rack proximal end portion 132 or a section 404 of the second rack 104 adjacent the second rack proximal end portion 152. The movable core member 110 includes a contact surface, which can be a surface 410 (FIG. 6) defined by the ledge 214, a surface 412 (FIG. 6) defined by the ledge 224, a surface 416 adjacent the receptacles 240, 242 or a surface 418 adjacent the receptacles 240, 242. The contact elements, i.e., the finger 314 and the section 402, move with the first rack 102 during pivotal movement of the first rack 102 with respect to the second rack 104. The contact elements, i.e., the finger 354 and the section 404, move with the second rack 104 during pivotal movement of the second rack 104 with respect to the first rack 102.
The contact elements, i.e., the finger 314 and the section 402 in the illustrated embodiment, are configured to contact the appropriate contact surface 410 or 416 to rotate the movable core member 110 along with the first rack 102 during at least a portion of the pivotal movement of the first rack 102 with respect to the second rack 104. For example, if the first rack 102 in the position shown in FIG. 10 was rotated in an opening direction, i.e., in the direction of arrow 420, the finger 314 would contact the contact surface 410 defined by the ledge 214 on the movable core member 110 to rotate the movable core member 110 with respect to the second rack 104 in the opening direction. Also, if the second rack 104 in the position shown in FIG. 10 was rotated in a closing direction, i.e., in the direction of arrow 422, the section 404 of the second rack 104 adjacent the second rack proximal end portion 152 would contact the surface 418 on the movable core member 110 to rotate the movable core member 110 with respect to the first rack 102 in the closing direction.
The contact elements, e.g., the finger 314 and the section 402 associated with the first rack 102 in the illustrated embodiment, are spaced from the respective contact surfaces 410 and 416 so as not to contact the contact surfaces 410 and 416 during at least a portion of the pivotal movement of the first rack 102 with respect to the second rack 104. For example, if the first rack 102 in the position shown in FIG. 10 was rotated in a closing direction, i.e., in the direction of arrow 424, the finger 314 would not contact the contact surface 410 defined by the ledge 214 and the section 402 would not contact the contact surface 416 until the first rack 102 contacts the second rack 104. As such, movement of the first rack 102 with respect to the movable core member 110 is also allowed.
With reference to FIG. 1, when the drying rack 100 is in the closed position, the first item support surface 178 (FIG. 2) faces the second item support surface 180 (FIG. 2). With reference to FIG. 3, when in the drying rack 100 is in the open use position the first item support surface 178 and the second item support surface 180 are oriented to support associated items to be dried. The movable core member 110 occupies an upright position when the drying rack 100 is in the open use position. When the movable core member 110 is in the upright position shown in FIG. 3, the receptacles 240, 242 are oriented to maintain the cleaning devices 126, 128 so that a longest dimension of each cleaning device 126, 128 is transverse (e.g., perpendicular) to the item support surfaces 178, 180. The movable core member 110 is rotatable to a storage position, which is shown in FIG. 11, rotationally offset (90 degrees in the illustrated embodiment) from the upright position. With reference to FIG. 11, angular movement of the second rack 104 with respect to the first rack 102 beyond a first predetermined angle, which is 90 degrees in the illustrated embodiment, in an opening direction, which would be in the direction of arrow 424 in FIG. 10, from the closed position toward the open use position (shown in FIG. 3) results in rotational movement of the movable core member 110 with respect to the first rack 102. However, angular movement of the second rack 104 with respect to the first rack 102 up to the first predetermined angle in the opening direction may not result in rotational movement of the movable core member 110 with respect to the first rack 102. In other words, angular movement of the second rack 104 with respect to the first rack 102 in the opening direction for the first 90 degrees may not result in rotational movement of the movable core member 110 with respect to the first rack 102.
It will be appreciated that various of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. By way of example, the exemplary drying rack was herein described for use with associated parts of a breast pump. However, it should be appreciated that the exemplary drying rack is not limited to that particular use and that alternative uses for the drying rack are contemplated.
