Description
FIELD OF THE DISCLOSURE

The present disclosure relates to a cloth rack and, more particularly, a double-decker cloth rack.


BACKGROUND OF THE DISCLOSURE

Currently known adjustable double-decker cloth racks are not sufficiently strong such that when the cloth rack is bearing near its maximum load, the rack can become shaky when a user pushes it to move it about on its wheels. This may cause damage to its plastic base, as well as causing separation of its couplers from its middle horizontal tube, thereby collapsing the entire cloth rack.


There is a continuing need for structurally sound cloth racks.


All referenced patents, applications and literatures are incorporated herein by reference in their entirety. Furthermore, where a definition or use of a term in a reference, which is incorporated by reference herein, is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply. The disclosed embodiments may seek to satisfy one or more of the above-mentioned needs. Although the present embodiments may obviate one or more of the above-mentioned needs, it should be understood that some aspects of the embodiments might not necessarily obviate them.


BRIEF SUMMARY OF THE DISCLOSURE

To overcome the deficiencies found in existing cloth rack designs, the instant disclosure provides a structurally re-enforced and ease-of-use cloth rack.


In one contemplated embodiment, the disclosure provides a double-decker cloth rack having a base and at least two vertical tubes extending from the base. There can be a middle horizontal tube disposed in between the two vertical tubes. The two terminal ends of the middle horizontal tube are each connected to a vertical tube via a tri-connect coupler. Each tri-connect coupler has a slit across a horizontal tube body on the outside of which has helical tracks.


There can be provided a locking nut to screw onto the helical track to decrease the divide of the slit, thereby tightening the horizontal tube body as the horizontal tube body envelopes the terminal end of the middle horizontal tube. This beneficially improves the structural integrity of the cloth rack especially when a heavy load is being carried by the cloth rack. Each vertical tube consists of a top tube and a bottom tube, both of which are connected to the tri-connect coupler. The top terminal end of each top tube is connected to a tri-connect horn coupler. Between the two tri-connect coupler is disposed a top horizontal tube. Each of the tri-connect horn coupler also connects to an extension piece. The extension piece telescopically inserts within the perspective terminal end of the top horizontal tube.


Preferably, the tri-connect horn coupler has an elbow corner structural support piece. The base includes two horizontal slats connecting two end pieces. Each of the end pieces can have a hollow body within which there can be two parallel transversely disposed support in the form of a short wall that connects one interior side of the end piece to the opposing interior wall of the end piece.


Each of the extension pieces can have at least one notch to indicate a depth to which the extension piece is inserted into the top horizontal tube.


There can also be end caps disposed at the distal end of each extension piece, which can be hollow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The different aspects of the various embodiments can now be better understood by turning to the following detailed description of the embodiments, which are presented as illustrated examples of the embodiments as defined in the claims. It is expressly understood that the embodiments as defined by the claims may be broader than the illustrated embodiments described below.


As shown in FIGS. 1-11, a double-decker cloth rack includes a base 1, at least two vertical tubes 2 that are coupled to the base 1. There can be a middle horizontal tube 3 that is disposed between the two vertical tubes 2. There can be a top horizontal tube 4 disposed between and coupled to the top ends of the two vertical tubes 2. There can be two tri-connect couplers 5 that functions to connect the two terminal ends of the middle horizontal tube 3 onto the two vertical tubes 2. There can be two tri-connect horn couplers 6 that functions to connect the top horizontal tube 4 to the top ends of the two vertical tubes 2.


In one embodiment, each of the tri-connect couplers 5 can include a vertical tube body 501, a vertical tube body 502 that functions to enclose a terminal end of the middle horizontal tube 3. Vertical tube body 502 and horizontal tube body 502 can be made of one integral part. As shown in FIG. 6, there can be a detachable locking nut 503 that can screw onto the vertical tube body 502 in order to clamp the vertical tube body 502 onto a terminal end of the middle horizontal tube 3. In one embodiment, the horizontal tube body 501, the vertical tube body 502, and the locking nut 503 each has a diameter that is different from one another.


Referring now to FIG. 3, each side of the vertical tubes 2 consists of two parts, a top tube 201 and bottom tube 202. Top tube 201 can be telescopically received within bottom tube 202. There can be a leaf spring push button 201a disposed within the top tube 201 to complementarily fit within openings 202a (see FIG. 4) disposed on the top portion of the bottom tube 202. By fitting the leaf spring push button 201a into the opening 202a, the top tube 201 and bottom tube 202 forms one sturdy vertical tube 2. Such structure is commonly known.


Referring now to FIG. 11, the tri-connect coupler 5 can have a vertical slit 501a disposed on a side of the vertical tube body 501 where the vertical tube body 502 is disposed. There can be a horizontal slit 502a disposed on the top and bottom sides of the horizontal tube body 502, thereby dividing the horizontal tube body 502 into two liked arcuate pieces. These two arcuate pieces are an integral part of the vertical tube body 501. Each of these two arcuate pieces is disposed opposite of each other on opposite sides of the vertical slit 501a. The horizontal slit 502a connects with the vertical slit 501a to make one single slit disposed on the tri-connect coupler 5.


On the outside of the vertical tube body 502 can be disposed helical tracks 502a to receive complementary grooves disposed on the inside wall of the locking nut 503.


Referring now to FIG. 8, there can be a structural support piece 601 disposed on the tri-connect horn coupler 6 to strengthen the structural integrity of the coupler 6.


Referring now to FIG. 4, similar to the base of known cloth racks, the herein disclosed base 1 can have two horizontal slats 101 coupled to two end pieces 102. The end piece 102 can be a plastic piece with a hollow interior. A bottom view of the end piece 102 is shown in FIG. 10. Within the hollow interior of the end piece 102 there can be two transversely disposed support pieces disposed near the end of the end piece 102. The two transversely disposed support pieces can provide structural integrity to the base 1.


Referring now to FIG. 3, the top horizontal tube 4 can have terminal extension pieces 7 disposed on either terminal ends of the top horizontal tube 4. Each extension piece 7 can have one or more scale notches 701 indicated on the side of the extension piece 7 so that a user would know the limit of the extension without overextending the extension pieces 7.


This is important because overextension may also damage the tri-connect horn coupler 6 when a heavy load of clothing forces the overextended extension piece 7 to collapse. If and when the tri-connect horn coupler is damaged, the entire cloth rack can be rendered useless.


Referring now to FIG. 7, the tri-connect horn coupler 6 can have a locking clamp 602. Locking clamp 602 can lockingly secure the extension piece 7 in place. Releasing of the locking clamp 602 unlocks the extension piece 7 thereby allowing the extension piece 7 to be freely removed from the tri-connect horn coupler 6.


Referring now to FIGS. 3 and 9, where an end cap 8 is shown disposed within the extension piece 7. The end cap 8 can have a round disc top 801 and an integral tube insert 802. The end cap 8 can fittingly insert within a terminal end of the extension piece 7, which is hollow.


It will, nevertheless, be understood that no limitation of the scope of the disclosure is thereby intended; any alterations and further modifications of the described or illustrated embodiments and any further applications of the principles of the disclosure as illustrated therein are contemplated as would normally occur to one skilled in the art to which the disclosure relates.
