## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a foot assembly, and more particularly to the foot assembly of a clothes rack to reduce occupied space when the rack is stored.
2. Description of Related Art
With reference to FIG. 6, a conventional clothes rack (6) is shown and has two opposite poles (60), a crossbar (70) securely connected to distal ends of the two poles (60) and two foot assemblies (80) respectively and securely connected to proximal ends of the two poles (60). Each foot assembly (80) has a first connector (81) and a second connector (82) formed on the foot assembly (80). The second connector (82) is to receive the proximal end of the pole (60) and the first connector (81) is to receive a distal end of a base bar (71). Two casters (83) are respectively mounted on opposed sides of each of the foot assemblies (80) to facilitate movement of the clothes rack (6). As shown in the drawing, it is noted that the foot assembly (80) except the casters (83) is integrally molded so that it is impossible to fold the clothes rack (6) when required. Therefore, the clothes rack (6) takes up a large space when in storage.
Because the living space in metropolitan areas is reducing due to continuous infrastructure development, how to effectively use the available space becomes an art for modern people. Therefore, the conventional clothes rack is obsolete and improvement is required.
To overcome the shortcomings, the present invention tends to provide an improved clothes rack to mitigate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an improved foot assembly of a clothes rack. The foot assembly is able to be folded such that storage space required for the clothes rack is compact.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1 and 2, the clothes rack (1) in accordance with the present invention includes a top crossbar (20), a bottom crossbar (21) and two stanchions (10) respectively sandwiched between two opposite ends of the top crossbar (20) and the bottom crossbar (21). A foot assembly (30) is extended from a joint between the stanchion (10) and the bottom crossbar (21). The foot assembly (30) has a first leg (31) and a second leg (41) extending in a direction opposite to that of the first leg (31). A joint (50) is provided between the first leg (31) and the second leg (41).
The first leg (31) has a first ring (32) formed on a proximal end thereof and a first caster (35) rotatably mounted on a distal end thereof. The first leg (31) has a first limiting recess (33) defined in an inner face of the first ring (32) at a top opening and a first finger (34) extending from the inner face of the first ring (32) at a bottom opening. The second leg (41) has a second ring (42) formed on a proximal end thereof and a second caster (45) rotatably mounted on a distal end thereof. The second leg (41) has a second limiting recess (43) defined in an inner face of the second ring (42) at a top opening and a shoulder (44) formed on the inner face of the second ring (42), also at the top opening. A slit (421) is defined in the inner face of the second ring (42) and plug (46) is provided to extend into a bottom opening of the second ring (42) of the second leg (41).
The joint (50) is composed of a third ring (51), a tube (52) extending from an outer periphery of the third ring (51) to receive one end of the bottom crossbar (21) and a tubular extension (53) integrally extending out from a bottom rim of the third ring (51). The tubular extension (53) is provided with a flange (54) on a bottom rim of the tubular extension (53), multiple cutouts (55) longitudinally defined through a peripheral edge of the tubular extension (53) as well as the flange (54), a positioning boss (56) extending into an interior of the tubular extension by piercing and a second finger (57) (shown in FIG. 3) extending from an inner face of the tubular extension (53). The tubular extension (53) has an outer diameter smaller than that of the third ring (51) and an inner diameter the same as that of the third ring (51) to allow extension of the stanchion (10) into the tubular extension (53). Due to the definition of the cutouts (55) in the tubular extension (53), the bottom end of the tubular extension (53) is able to be deformed when encountering a resistance.
It is to be noted that the first limiting recess (33) is defined in 90 degrees in the first ring (32) and the second limiting recess (43) is defined in 180 degrees in the second ring (42).
With reference to FIG. 3, when the foot assembly of the present invention is assembled, it is noted that the proximal end of the stanchion (10) is inserted into the third ring (51), the first ring (32) and the second ring (42) with the tubular extension (53) inserted into the first ring (32) and the second ring (42) as well. After the tubular extension (53) is inserted into the first ring (32) and the second ring (42), the second finger (57) is received in the first limiting recess (33) and the first finger (34) is received in the second limiting recess (43). Furthermore, when the flange (54) of the tubular extension (53) is inserted into the second ring (42), abutment of the flange (54) to the shoulder (44) forces the bottom edge of the tubular extension (53) to deform such that the flange (54) is able to extend over the shoulder (44) and then the same bottom edge springs back to lock with the second ring (42). Further, the positioning boss (56) is inserted and received in the slit (421) of the second ring (42). Finally, the plug (46) is inserted to cover the bottom opening of the second ring (42).
With reference to FIGS. 4 and 5, when the clothes rack (1) of the present invention is to be folded for storage, the user is able to pivot the first leg (31) and the second leg (41) to align with each other. That is, due to the first finger (34) being received in the second limiting recess (43) and the second finger (57) being received in the first limiting recess (33), the first leg (31) is able to pivot relative to the second leg (41) and the second leg (41) is able to pivot relative to the first leg (31) to align with one another. While the second leg (41) is being pivoted, the positioning boss (56) will be forced out of the slit (421) by a periphery defining the slit (421) and when the second leg (41) is returned, the positioning boss (56) is again received in the slit (421) to temporarily lock the foot assembly of the present invention.
Because the first leg (31) and the second leg (41) are able to be pivoted so as to align with one another, the storage space required for the clothes rack is small and thus the user is able to use the available space effectively.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
