Description

FIELD

[0002] The invention relates to sinks and portable storage cabinets and, in particular, to a sink with a foldable faucet assembly and a multi-purpose portable support cabinet.

BACKGROUND

[0003] Over the years, outdoor and garden or backyard activities have become increasing popular. However, workplace and family demands in today's busy lifestyles often leave little time to organize and assemble all the necessary gear, such as gardening implements or food preparation and serving utensils prior to commencing such activities and then for cleaning and reorganizing such equipment after the activity is over. Gardening or barbecue accessories, for example, are often stored haphazardly out of sight in garages or basements and in boxes for extended periods of time, such as during the cold weather months, and then have to be retrieved at a moment's notice for the first warm and sunny afternoon.

[0004] In addition to convenient storage, easy access to a sink for cleaning outdoor equipment and utensils of the various outdoor activities is particularly desirable. U.S. Pat. No. 5,349,708 to Lee discloses a foldable kitchen sink that includes two support members that are hinged to each other such that their upper surfaces may be deployed in a facing folded position or in a coplanar unfolded position. One support member has a dishwasher bucket mounted thereto; the other support member has a grille mounted thereto. The sink can be folded and transported, but does not include a faucet assembly for connection to a water supply.

[0005] U.S. Pat. No. 6,131,929 to Haley discloses a portable modular cart and game table that includes a faucet assembly and a sink basin mounted on the upper surface of the cart. A cover is connected to the cart and is movable between a first position that overlies the sink basin and a second position providing access to the sink basin. The faucet assembly is rotatable 360 degrees and collapsible, so that the faucet assembly assumes the upright position when the cover is in the second position and collapses axially when the cover is in the first position. The location of the faucet assembly occupies desirable counter top area which could be used to support utensils and other items.

[0006] There remains, therefore, a need for a sink with the faucet assembly that can be installed on outdoor equipment and that includes features that overcome the limitations, shortcomings and disadvantages of other sinks without compromising their advantages.

SUMMARY

[0007] The invention meets the identified needs, as well as other needs, as will be more fully understood following a review of this specification and drawings.

[0008] In one general aspect, a sink may include a basin and a faucet assembly foldably mounted relative to the basin. The faucet assembly is rotatable between an upright position wherein the faucet assembly protrudes out from the basin and a folded position wherein the faucet assembly is received within the basin.

[0009] Aspects of the invention also may include embodiments of a serving cart, a gardening cart and a barbecue station, each including a sink with a foldable faucet assembly and a slidable table portion or pivotable lid for covering the sink when the faucet assembly is in the folded position. The barbecue station may include a utility receptacle with a corresponding lid and an enclosed storing space with divided compartments, drawers and trays, which are accessible by opening one or more doors.

DETAILED DESCRIPTION

[0030] Referring now to the drawings for the purpose of illustrating the invention and not for the purpose of limiting the same, it is to be understood that standard components or features that are within the purview of an artisan of ordinary skill and do not contribute to the understanding of the various embodiments of the invention are omitted from the drawings to enhance clarity, even when such features may otherwise be necessary for the function of a sink embodying the invention. In addition, it will be appreciated that the characterizations of various components described herein as moving, for example, upwardly or downwardly, or being vertical or horizontal, are relative characterizations only based upon the particular position or orientation of a given component for a particular application.

[0031] FIGS. 1 and 2 depict an embodiment of a sink 100 according to the invention. The sink 100 includes a basin 102 having a drain 104. A two-sided drain stopper 106, shown in more detail in FIG. 3, may be used to strain liquid exiting the basin through the drain 104 or to plug the drain 104. The basin 102 may be produced and assembled from food-grade materials when the sink 100 is to be used for food preparation and serving. It will be appreciated, however, that the basin 102 could be fabricated from a myriad of other suitable materials, such as stainless steel, aluminum, etc., and be provided in a variety of different shapes. The sink 100 may also include a soap tray 110 and other support surfaces, which may be molded in the basin 102. A faucet assembly 108 is mounted on the basin 102 and includes a discharge neck 112, a handle 114 or other suitable lever or knob for controlling liquid flow through the faucet assembly 108.

[0032] As indicated above, this embodiment of the sink 100 also employs a unique and novel faucet assembly 108. In this embodiment, the faucet assembly 108 includes a faucet housing 116 that pivotally supports the discharge neck 112 on the basin 102. More particularly and with reference to FIGS. 3(a) and (b), the faucet housing 116 is generally hollow and may be fabricated in two pieces that are retained together by, for example, screws, adhesive, etc. The skilled artisan will readily appreciate that by employing screws to affix the portions of housing 116 together, the user can quickly disassemble the housing 116 to replace any of the components therein.

[0033] The faucet housing 116 supports a flow control valve 120 that includes a valve housing 122 that is supported in the faucet housing 116 by a mounting collar 121 that includes an inlet conduit barb 128. See FIG. 3(b). An O-ring 123 is fitted between the valve housing 122 and the collar 121. The inlet conduit barb 128 defines an inlet passage 129. Likewise, an outlet mounting flanged connector 130 is supported through an O-ring on the valve housing 122 opposite the inlet conduit barb 128 and defines an outlet passage 132 therethrough. The discharge neck 112 may be rotatably received on the outlet mounting flanged connector 130 for rotational travel thereon about an axis “A-A”. See FIG. 3(a). Rotatably supported in the housing 122 between the inlet passage 129 and outlet passage 132 is a flow control member 124′. The flow control member 124′ has a flow passage 125 therethrough that, when aligned with the inlet passage 129 and outlet passage 132, permits a fluid entering through the inlet passage 129 to flow through the valve 120.

[0034] In the embodiment depicted in FIG. 3(a), an actuator stem 136 is attached to a side connector 127 of the valve housing 122. The actuator stem 136 is rotatably supported in a portion of the faucet housing 116, as shown in FIG. 3(c), and has a handle 114 attached thereto. The handle 114 permits the user to selectively rotate the flow control member 124′ about an actuator axis “B-B”. Thus, when the flow control member 124′ is rotated such that the flow control passage 125 is aligned with the inlet passage 129 and the outlet passage 132, fluid can flow through the valve 120. If the flow control passage 125 is oriented at a ninety-degree angle to the inlet passage 129 and the outlet passage 132, no fluid is permitted to pass through the valve 120.

[0035] A supply conduit 124, which is coupled to a source of liquid, passes through a hole 142 in the faucet housing 116. In this embodiment, the supply conduit 124 may comprise a section of flexible hose which is coupled to the inlet conduit barb 128 by, for example, conventional means, such as a hose clamp 139. A flanged mounting bushing 144 that has a passage therethrough supports the supply conduit 124 where it enters the faucet housing 116. As can be seen in FIG. 3(a), the mounting bushing 144 also provides a means for pivotally coupling the faucet housing 116 to the basin 102. Protruding out through a hole 146 in an opposite side of the housing 116 is a mounting peg 148. The mounting peg 148 is provided with a flanged portion 150 that is larger than the hole 146 to prevent the mounting peg 148 from passing completely through the hole 146. The flanged portion 150 may include grooves that mate with corresponding protrusions in the faucet housing 116 to retain the mounting peg 148 in position. Alternatively, a biaser cavity 152 may be provided in the housing 116 for supporting a biasing member in the form of a spring to bias the mounting peg 148 in an outward direction away from the faucet housing 116.

[0036] To install the faucet assembly 108 on the sink, the faucet housing 116 is inserted into a cavity 156 in the sink 102. The cavity 156 may include a first mounting enclosure 158 receiving the mounting bushing 144 and a second mounting enclosure 160 receiving the mounting peg 148. A first mounting cover 162 may be inserted over the top of the first enclosure 158. The first mounting cover 162 snaps in over the mounting bushing 144 and secures it in place. Similarly, a second mounting cover 164 may be inserted over the top of the second mounting enclosure 160, snapping in over the mounting peg 148. See FIGS. 3(a), 3(d) and 3(e). The first mounting cover 162 and the second mounting cover 164 may also be secured to the basin 102 with hidden fasteners, such as screws that are threaded from the outer surface of the basin through holes located on molded surfaces of the first and second mounting enclosures 158, 160.

[0037] Other ways of supporting the faucet housing on the basin of the sink are within the purview of one of ordinary skill in the art. For example, the mounting bushing 144 and the mounting peg 148 may be received within respective holes in the walls of the basin, in connection with the embodiment described above that includes a spring in the biasing cavity 152. The spring facilitates retention of the mounting peg 148 in its respective hole to retain the faucet housing 116 in the basin 102. It will be appreciated, however, that such arrangement would permit the faucet assembly 108 to be detached from the basin 102, if desired, for storage purposes, repair purposes, etc.

[0038] When the mounting bushing 144 is received in the first mounting enclosure 158 and the mounting peg 148 is received in second mounting enclosure 160, the person of ordinary skill in the art will appreciate that the faucet assembly 108 can pivot about an axis “D-D” defined by the mounting bushing 144 and mounting peg 148. See FIG. 3(a). In particular, the faucet assembly 108 may be pivoted through an angle of approximately ninety degrees from an upright position shown in FIG. 1, wherein at least a portion of the faucet assembly 108 protrudes from the basin to other positions including a folded storage position inside the basin 102, such that the entire faucet assembly 108 is below a plane “E-E” defined by the top 103 of the basin 102. See FIG. 5. The basin 102 may include a retainer 113 that releasably retains the faucet assembly 108 in the folded position. The retainer 113 may be fabricated as an integral part of the basin 102, by molding, for example. The rear surface of the faucet housing 116 may include two symmetric pivot detents 117, which may be attached or molded thereon, to facilitate pivoting the faucet assembly 108 against an interior rear surface 111 of the basin 102 and to stabilize the faucet assembly 108 in the upright position.

[0039] In one embodiment of the invention, the above-described sink 100 may be employed in a sink assembly, generally indicated as 200. The sink assembly 200 may include a sink housing 202 that has a top portion 204 with a top surface 203 and a mounting bracket 206. See FIG. 6. The top portion 204 includes a top recess 208 in which the sink 100 may be received. The sink assembly 200 may be fabricated from blow molded plastic or other suitable processes and materials that are relatively lightweight and that can withstand the elements, if stored outside. However, the sink assembly 200 could also be fabricated from a myriad of other materials such as steel, stainless steel, aluminum, etc.

[0040] The sink assembly 200 may be mounted on a wall or other convenient structure and may include a rack 210 for coiling a garden hose 212 or other conduit therearound.

[0041] The sink assembly 200 may also include a pair of table portions 220 that are slidably affixed to the sink housing 202 for moving between open positions shown in FIG. 6 and closed positions shown in FIG. 7. Each of the table portions may have, for example, a protrusion 230 that slides into a mating recess 231 formed by guides 232 on the top portion 204 of the sink housing 202. See FIG. 7(a). The top portion 204 may be provided with stops to prevent the table portions 220 from sliding completely off the sink assembly 200. Those of ordinary skill in the art will appreciate that the table portions 220 may slide either together or independently of each other on the top portion 204 of the housing 202 to fully expose, partially cover or completely cover and protect the sink 100 when the faucet assembly 108 is in the folded position, and provide work and preparation surface area.

[0042] The sink housing 202 includes an inlet opening 222 for connection with the water supply conduit 124, and an outlet opening 224 for connection with a draining conduit 138. See FIG. 7, and FIG. 3(a) for the sink 100. The supply and draining lines may be conveniently connected through a connecting manifold 170, shown in FIGS. 8(a) and (b), that can be mounted on a side 225 of the sink assembly 200, either by conventional fasteners, such as screws or by snap-fitting on the side 225 of the sink assembly 200 by means of resilient snap lugs 172, which are, for example, integrally molded on the connecting manifold 170, when the connecting manifold is made of plastic material. The connecting manifold 170 includes a manifold outlet 174 and a manifold inlet 176. A manifold outlet or drain connector 184 may be inserted through the manifold outlet 174 and connect the drain conduit 138 to an extension drain conduit 185, and a manifold inlet connector 186 may be inserted through the manifold inlet 176 and connect the fluid supply conduit 124 to an extension supply conduit 183.
