The present invention relates generally to laundry drying racks, and more particularly to collapsible laundry drying racks.
Conventional laundry drying racks may be used to dry laundered items when the laundered items are too delicate to be placed in an electric dryer because the laundered items may shrink when exposed to excessive heat. Laundry drying racks may also be used to temporarily store clothes during ironing tasks. For example, a user may place a plurality of ironed shirt on the laundry rack to prevent the ironed shirts from wrinkling as would occur if the ironed shirts were stacked upon each other.
In order to minimize the price of the laundry drying rack to an end consumer, the laundry rack may be sold, packaged and shipped in a partially disassembled state. The end consumer or user would finish assembly of the laundry rack upon purchase and receipt of the laundry rack. This permits the laundry drying rack manufacturer to shift the cost of manufacturing the laundry drying rack to the end consumer thereby lowering the price of the laundry drying rack to the end consumer at the retail level. Further, packaging and shipping the laundry drying rack in the partially disassembled state reduces the size of the shipping package of the laundry drying rack thereby reducing the cost to ship the laundry drying rack from the manufacturer to the retail store or the end consumer. Unfortunately, conventional laundry drying racks, frequently comprise numerous components which makes assembly difficult and time consuming. Further, use of fasteners for the assembly may further require tools for the attachment thereof. Accordingly, it may be unfeasible to shift the cost of assembly to the end consumer.
Accordingly, there is a need in the art for an improved laundry drying rack.
The laundry rack discussed herein addresses the problems identified above, discussed herein and those that are known in the art.
The laundry rack may be collapsible from an upright position to a folded position. In the upright position, the laundry rack may have a plurality of cross members spread apart such that a user may hang clothes for air drying the same. In the folded position, the laundry rack has a compact configuration for storage and/or shipment. The laundry rack may comprise a first scissor structure and a second scissor structure. The cross members may be disposed therebetween in parallel relationship and attached to the first and second scissor structures.
The cross members may be attached to the first and second scissor structures via tab connectors and socket connectors. In a first embodiment of the laundry rack, the tab connectors may be attached to distal ends of the cross members. Also, the socket connectors may be attached to the first and second scissor structures at mutually corresponding locations. The tab connector is selectively removable from the socket connector. In particular, the tab connector may comprise a tab portion having release levers formed with retention members. When the release levers are inwardly pressed together, the retention members are also inwardly deflected.
The socket connector may have a socket portion having a through hole. The through hole is sized and configured to receive the tab portion of the tab connector. The sidewall of the socket portion is also formed with a U-shaped cut out to permit the cross member to extend from the tab portion and through the U-shaped cut out.
To engage the socket connector to the tab connector, the tab portion is inserted into a gate of the through-hole of the socket portion with the retention members pointed toward the through hole. As the tab portion proceeds through the through hole, retention members of the tab portion deflect inwardly due to the inner surface of the through hole. Also, the cross member may be received into the U shaped cut out. When the tab portion is fully inserted into the through hole, the retention members engage cam edges of the socket portion preventing removal of the tab portion from the socket portion. Also, the cross member is received into the U shaped cut out preventing the tab portion from slipping out of the through hole at an exit thereof. At this point, the tab connector is connected to the socket connector and may be removed only by depressing the release levers. To remove the tab portion from the socket portion, the release levers are deflected inwardly which also deflects the retention members inwardly to disengage the retention members from the cam edges. The user may then remove the tab portion from the socket portion.
These and other features and advantages of the various embodiments disclosed herein will be better understood with respect to the following description and drawings, in which like numbers refer to like parts throughout, and in which:
As a preliminary matter, references to upper, lower, right, left, forward and rear are for convenience and are not meant to limit the scope of the aspects of the laundry rack.
Referring now to the drawings which are for the purposes of illustration and not for the purposes of limiting the laundry rack 10 which will be described herein,
The laundry rack 10 may comprise a first scissor structure 14 and a second scissor structure 16 (see
As stated above, the laundry rack 10 is traversable between the folded position and the expanded position. To retain the laundry rack 10 in the expanded position, the upper rack portion 18 is selectively engageable to a locking cross member 12a attached to the upper left most corner of the first and second scissor structures 14, 16. When the laundry rack 10 is traversed to the expanded position, the upper rack portion 18 may be engaged to the locking cross member 12a. In this manner, upper distal ends of the first and second scissor structures 14, 16 are prevented from expanding away or contracting toward each other. Hence, the laundry rack 10 remains in the expanded position. To collapse the laundry rack 10, the upper rack portion 18 is disengaged from the locking cross member 12a. The laundry rack 10 may then be pushed down toward the ground to traverse the laundry rack 10 to the folded position.
The upper rack portion 18 may be locked onto the locking cross member 12a, as shown in
As shown in
Moreover, the laundry rack 10 may be provided as a kit containing the first scissor structure 14, the second scissor structure 16 and a plurality of cross members 12 which may be selectively attachable to the first and second scissor structures 14, 16. To assemble the laundry rack 10, the user may attach the locking cross member 12a (see
In a first embodiment, the cross members 12 are attachable to the first and second scissor structures 14, 16 via a set of tab connector 30 and socket connector 32. The tab connector 30 is more particularly shown in
The socket connectors 32 may be attached to the first and second scissor structures 14, 16. Also, the tab connectors 30 may be engaged to and removed from the socket connectors 32 to engage or remove the cross members 12 from the scissor structures 14, 16, as shown in
The retention members 48 may have a hook configuration, as shown in
The socket connectors 32 may be attached to the first and second scissor structures 14, 16 at pre-determined corresponding location. As shown in
An optional sliding washer may be fitted between the legs at each linkage joint 74 which permit rotational movement therebetween despite the existence of a compressive force caused by the socket portion 60 and the head of the screw 66. At every linkage joint 74 of the first and second scissor structures 14, 16, the sliding washer may be interposed between the legs, and the post portion 62 may be inserted into aligned holes. In this alternative configuration, the throat distance 72 of the post portion 62 of the socket connector 32 may be slightly smaller compared to the sum of the thicknesses of the two legs and the sliding washer. When the screw 66 is tightened onto the post portion 62, the screw 66 may be torqued onto the legs. Fortunately, the sliding washer permits rotational movement between the two legs despite the compressive force of the screw 66 and the post portion 62.
Alternatively, in a second embodiment of the laundry rack shown in
The tab connector 104 may be connected to the legs of the first and second scissor structures 14, 16 in a similar manner that the socket connectors 32 discussed above in relation to the first embodiment are connected to the legs.
The tab connector 104 may have a tab portion 124, a spacer 122, a collar 126, and a post portion 128. The collar 126 and the tab portion 124 may be coaxially aligned to each other and connected to each other via a spacer 122. The collar 126 may define a lateral side 130 and a medial side 132. The spacer, 122 may be connected to the collar 126 on its lateral side 130, and the tab portion 124 may be connected to the spacer 122 on the opposite side of the collar 126. The post portion 110 may be coaxially aligned to the collar 126 and connected to the collar 126 on the medial side 132. The tab portion 124, spacer 122, collar 126 and post portion 110 may be formed of a unitary material.
To connect the tab connectors 104 to the legs of the first and second scissor structures 14, 16, the post portions 110 of the tab connectors 104 are inserted into apertures 134 formed in the legs of the first and second scissor structures 14, 16. For example, to connect the tab connector 104 to the first and second legs 20, 22 of the upper rack portion 18, the post portion 110 is inserted into the aperture 134 formed in the leg until the collar 126 contacts the leg to limit the insertion distance of the post portion 110 into the aperture 134. A screw 136 is then threaded onto internal threads formed in the post portion 110 to lock the axial location of the tab connector with respect to the leg. As discussed above in the first embodiment, a throat distance 72 of the post portion 62 may be shorter compared to the thickness of the leg to permit the screw 66 to clamp the tab connector 30 down on the leg. The medial side of the collar may have a nub or detent 68 which is received into a detent aperture 70 formed on the leg when the collar contacts the leg or when the post portion 62 is inserted into the aperture 64. This locks the rotational movement of the tab connector 30 with respect to the leg. When the tab connectors 30 join two legs at a linkage joint 74, the throat distance 72 of the post portion 62 may be slightly longer than the thickness of the legs to permit the legs of the first and second scissor structures 14, 16 to pivot with respect to each other. A sliding washer may be interposed between two legs to promote pivotal motion of the legs, as discussed in relation to the first embodiment. The tab connectors 30 may be attached to the first and second scissor structures 14, 16 at corresponding locations throughout the entire first and second scissor structures 14, 16.
As in the first embodiment, the second embodiment of the laundry rack 10 may be provided to the user in a disassembled state to reduce the storage volume of the laundry rack 10 thereby reducing transportation costs to the consumer and to shift a portion of the laundry racks manufacturing cost to the consumer thereby reducing the price of the laundry rack.
The laundry rack 10 may be provided to the consumer as a kit containing the first scissor structure 14, the second scissor structure 16 and a plurality of cross-members 102 which may selectively attachable to the first and second scissor structures 14, 16. In this second embodiment, the socket connectors 106 are connected to distal ends of the cross members 102 and tab connectors 104 are connected to the first and second scissor structures 14, 16. To assemble the laundry rack 10, the user may attach the locking cross member 12 to the upper left distal portions of the first and second scissor structures 14, 16. In particular, the user aligns the gate 146 of the through hole 118 of the socket portion 108 toward the retention members 148 of the tab portion 124. The retention members 148 of the second embodiment may have a similar configuration as the retention members 48 of the first embodiment. The socket portion 108 is then pushed onto the tab portion 124 thereby traversing the tab portion 124 into the through hole 118 of the socket portion 108. As the tab portion 124 is being traversed through the through hole 118, the retention members 148 are inwardly deflected by inner surfaces of the through hole 118. Also, the retention members 148 engage the cam edges 150 of the socket portion 108 to prevent removal of the socket portion 108 from the tab portion 124 when the tab portion 124 is fully inserted into the socket 118. Also, the spacer 122 of the tab connector 104 is received into the U-shaped cutout 120 of the socket portion 108. When the retention members 148 engage the cam edges 150, the spacer 122 is fully received into the U-shaped cutout 120. The U-shaped cutout 120 and the spacer 122 permit the sidewall of the socket portion 108 to be received between the collar 126 and the tab portion 124 when the socket connector 106 is fully engaged to the tab connector 104.
With the locking cross member 12a attached to the first and second scissor structures 14, 16, the first and second legs 20, 22 of the upper rack portion 18 may be engaged to the locking cross member 12a, as shown in
The laundry rack 10 is now in the expanded position or upright position. To traverse the laundry rack 10 to the folded position, the upper rack portion 18 is disengaged from the locking cross member 12a. The first and second scissor structures 14, 16 are pushed downward to fold the first and second scissor structures 14, 16 upon each other. The upper rack portion 18 is then laid against the first and second scissor structures 14, 16 and the laundry rack 10 is now traversed to the folded position.
The cross members 102 may be removed from the first and second scissor structures 14, 16 in the following manner. First, the release levers of the tab portion are inwardly deflected by pressing finger platforms together. When the release levers are inwardly deflected, retention members 148 of the tab portion 124 are also inwardly deflected which disengage the retention members 148 from the cam edges 150. The tab portion 124 may then be slipped out of the socket portion 108 to remove the cross members 102 from the first and second scissor structures 14, 16.
In both the first and second embodiments, the legs of the first and second scissor structures 14, 16 are preferably between about six (6) inches and thirty-six (36) inches in length, and more preferably the legs are about nineteen (19) inches in length, but the legs may also be longer or shorter. The legs preferably have a width of about ⅞ of an inch and a height of about ½ of an inch, but the members may have any desired configuration and dimensions depending, for example, upon the type of material used to construct the legs and the intended use of the laundry rack 10.
The legs 20, 22 of the upper rack portion 18 are preferably about fourteen (14) inches in height and the legs have a generally C-shaped cross section with a width of about ⅞ of an inch and a length of about ½ of an inch, but the legs may have different configurations and dimensions.
The cross members 12, 102 which interconnect the first and second scissor structures 14, 16 are preferably between about twelve (12) inches and sixty (60) inches in height and more preferably about twenty-nine (29) inches in height, but the cross members 12, 102 may be longer or shorter. The cross members 12, 102 are preferably plastic tubes with walls of about 1/16 of an inch thick and the cross members 12, 102 have an outside diameter of about ⅜ of an inch, but the cross members 12, 102 may have any desired configuration and size. The cross members 12, 102 are preferably hollow tubes for decreased weight, but the cross members 12, 102 may also be solid for increased strength. Additionally, the cross members 12, 102 may have a generally smooth cylindrical exterior surface to prevent laundry from snagging or catching on the cross members 12, 102. Alternatively, the cross members 12, 102 may have any desired shape, such as square or rectangular, and the cross members 12, 102 may be constructed from any materials such as wood or metal. The cross members 12, 102 may also include coating or layer of material, for example, to help prevent laundry from catching or snagging on the cross members 12, 102.
The components of the laundry rack 10 are preferably constructed from plastic, and more preferably from a thermal plastic resin such as polyvinyl chloride (PVC), but other types of plastic such as polyethylene, polypropylene or ABS may also be used. The plastic components are preferably designed to withstand temperatures of over 120° F. so that the laundry rack 10 does not melt or deform when used outdoors and the plastic is preferably treated by known means to resist damage from the sun, including protection from ultra violet (UV) and infrared radiation. Advantageously, the plastic components increase the life expectancy of the laundry rack 10 and the rack 10 may be used both indoors and outdoors. It will be understood that the laundry rack 10 can also be constructed from other types of plastics and other materials such as metals or composites, or wood.
The components of the laundry rack 10, including the cross members 12, 102, first and second scissor structures 14, 16 desirably fit into a small bag or enclosure for shipping and storage. Because the unassembled or partially assembled stand 10 fits within a small, compact bag or enclosure, this significantly reduces shipping, transportation and storage costs.
Although the laundry rack 10 discussed above has four (4) cross members 12, 102 forming the upper rack portion 18 and three (3) cross members 12, 102 forming the lower racks, it is also contemplated that the tab connectors 30, 104 and socket connectors 32, 106 may be disposed on the legs and the cross members 12, 102 in other configurations. For example, the lower racks and the upper rack 18 may have two (2) or more cross members 12, 102.
The first and second scissor structures 14, 16 may each comprise a plurality of legs which are arranged to expand or contract when the laundry rack 10 is traversed between the upright position and the folded position, respectively. In the upright position, the legs may have a generally X-shaped configuration, but the legs may also be aligned at other angles. Although not shown in the accompanying drawings, in the folded position, the legs are placed generally parallel or adjacent to each other. It will be understood that other types of legs, such as straight, curved, telescoping, etc., may be used with the laundry rack 10.
In an aspect of the tab connectors and the socket connectors, the same may be employed in other types of structures such as a shoe rack, table, night stand, laundry basket, and the like. By way of example and not limitation, with respect to the shoe rack, the same may have a first sidewall structure and a second sidewall structure. The first and second sidewall structures may have a scissor configuration similar to the first and second embodiments of the laundry rack. Alternatively, the first and second sidewall structures may have a flat rigid construction. The first and second sidewall structures may have a plurality of tab connectors attached thereto. The tab connectors attached to the first sidewall structure may be aligned to the tab connectors attached to the second sidewall structure. A cross member having socket connectors attached to distal ends of the cross member may be removeably engageable to the first and second sidewall structures via the tab connectors and the socket connectors.
The tab connectors may be positioned on the first and second sidewall structures such that the cross members form shoe support platforms sized and configured to receive one or more pairs of shoes. In particular, the cross members may form one or more levels or shelves (i.e., shoe support platform) or receiving the pairs of shoes. Each level may have a forward cross member and a rear cross member. The rear cross member is positioned to support the heel of the shoe. More preferably, the rear cross member is positioned such that the shoe's heel hooks onto the rear cross member. The forward cross member is positioned to support the outsole of the shoe. Preferably, the forward cross member is positioned at a lower elevation compared to the rear cross member such that the shoe is tilted forward when heel of the shoe is hooked on the rear cross member and outsole is rested on the forward cross member.
By way of example and not limitation, the shoe rack may have one level or shoe support platform for storing pairs of shoes. In particular, the shoe rack may have first and second sidewall structures. Each side wall structure may comprise a first leg and a second leg forming an X configuration when spread open. The legs may define an upper distal end and a lower distal end. The legs may be pivotally joined to each other about a middle portion thereof defining a joint. The upper distal end of the first leg may be positioned at a higher elevation compared to the upper distal end of the second leg. A tab connector may be attached to the upper distal ends of the first and second legs. A tab connector may be attached to the first and second sidewall structures at the joints thereof. A cross member may be attached to the tab connector attached at the joints for stabilizing the shoe rack. An upper rack portion may pivot about the upper distal end of the second legs of the first and second sidewall structures. The upper rack portion may lock to the cross member attached to the upper distal ends of the first legs thereby fixing the shoe rack in an erected position. At this point, the first and second sidewall structures cannot expand or collapse due to the upper rack portion being locked to the cross member (i.e., locking cross member). The cross member attached to the upper distal ends of the first legs of the first and second sidewall structures may be higher than the cross member attached to the upper distal ends of the second legs of the first and second sidewall structures. Alternatively, the cross member attached to the upper distal ends of the first legs of the first and second sidewall structures may be level with the cross member attached to the upper distal ends of the second legs of the first and second sidewall structures in a similar manner compared to the first and second embodiments of the laundry rack. The lower distal ends of the first and second legs may be level with each other such that the shoe rack may be rested on the ground in a similar manner compared to the first and second embodiments of the laundry rack. The user may rest his/her shoes on the cross members by resting the heel of the shoe on the cross member attached to the upper distal ends of the first legs and resting the outsole on the cross member attached to the upper distal ends of the second legs.
It is also contemplated that the socket connectors may be attached to the first and second sidewall structures, and the tab connectors may be attached to the cross members. The tab connectors and socket connectors may be attached to the cross members or the first and second sidewall structures in a similar fashion discussed in relation to the first and second embodiments of the laundry rack.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
