Article Support Rack
Abstract
A telescopic article support rack includes a primary article
support rack, a secondary article support rack, and a clamp. A
slide guiding device is disposed between the primary and the
secondary article support racks for guiding the primary and the
secondary article support racks slide relative with each other. One
end of the clamp buckles on the primary article support rack, and
the other end buckles on the secondary article support rack when
the secondary article support rack is pulled or pushed to a needed
position so as to make the primary and the secondary article
support racks fixed relatively. The clamp is a double-faced clamp
that can fix something in two opposite directions. Since the
secondary article support rack can be extended or telescoped
freely, the article support rack not only can meet the user's
requirement of placing more objects, but also can avoid wasting
room space when there is no need for placing more objects.

Description
CROSS REFERENCE TO THE RELATED PATENT APPLICATION
[0001] This application claims the priority of the Chinese patent
application No. 200620064774.1, filed on Sep. 25, 2006.
FIELD OF THE INVENTION
[0002] The present invention relates to an article support rack,
and more particularly to a telescopic article support rack.
BACKGROUND OF THE INVENTION
[0003] As shown in FIG. 1, a conventional article support rack 9
has a shelf-board 91 and a plurality of support legs 92 joined to
the shelf-board 91. After the article support rack is made to be a
finished product, the space on which for placing objects is
changeless. So the article support rack can not meet the user's
requirement of placing more objects on it. The user has to buy
another article support rack for holding more objects or a smaller
article support rack used side by side with the old article support
rack. The two ways both can solve the problem of incapable of
placing more objects, but the article support racks occupy much
more room space. It is a waste of space when the user does not need
to place more objects. With the state that per inch ground worth an
inch gold, the waste of the space is the matter that the users are
not willing to see.
[0004] Hence, a need has arisen for providing an improved article
support rack to meet the requirement of occasionally holding more
objects and avoid wasting room space when having no use for holding
objects.
SUMMARY OF THE INVENTION
[0005] Accordingly, an object of the present invention is to
provide a telescopic article support rack which is capable of
placing more objects when required and avoiding wasting room space
when there is no need for placing more objects.
[0006] To achieve the above-mentioned object, an article support
rack comprises a primary article support rack having a primary
article support rack with a first shelf-board and a plurality of
support legs joined to the first shelf-board, a secondary article
support rack with a second shelf-board and a plurality of support
legs joined to the second shelf-board, and a clamp. The first
shelf-board forms a first rail, and the second shelf-board forms a
second rail and a third rail. A slide guiding device is disposed
between the primary article support rack and the secondary article
support rack for guiding the primary article support rack and the
secondary article support rack slide relative with each other. One
end of the clamp forms a first split ring, and the other end of the
clamp forms a second split ring and a third split ring which are
symmetrical and have opposite splits. The first split ring buckles
on the first rail of the primary article support rack, the second
split ring and the third split ring selectively buckle on the
corresponding rails of the secondary article support rack. An inner
diameter of the first split ring is larger than an outer diameter
of the first rail, an inner diameter of the second split ring is
larger than an outer diameter of the second rail, and an inner
diameter of the third split ring is larger than an outer diameter
of the third rail.
[0007] In comparison with the traditional article support rack, the
advantage of the present invention is that the article support rack
of the present invention not only can be extended to meet the
user's requirement of placing more objects, but also can be
telescoped to avoid wasting room space when there is no need for
placing more objects.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
[0017] As shown in FIG. 2 and FIG. 3, the article support rack 1 of
the present invention includes a primary article support rack 2, a
secondary article support rack 3 and a clamp 4 (shown in FIG. 7).
The primary article support rack 2 includes a first shelf-board 21
with a first rail 27, several support legs 22 joined to the first
shelf-board 21, and a track bracket 23 positioned under the first
shelf-board 21. The secondary article support rack 3 includes a
second shelf-board 31 with a second rail 34 and a third rail 35,
several support legs 32 joined to the second shelf-board 31, and
limiting beams 33. The support legs 22, 32 of the primary article
support rack 2 and the secondary article support rack 3 each have a
truckle 24.
[0018] A slide guiding device is disposed between the primary
article support rack 2 and the secondary article support rack 3,
through which the primary article support rack 2 and the secondary
article support rack 3 can slide relative with each other.
[0019] As shown in FIG. 4 and FIG. 5, the slide guiding device of
the article support rack according to the present embodiment is the
track bracket 23 positioned on the primary article support rack 2.
The second shelf-board 31 of the secondary article support rack 3
slides along the track bracket 23 so as to achieve the relative
slide between the primary article support rack 2 and the secondary
article support rack 3.
[0020] The track bracket 23, which is frame-structure, includes two
slide tracks 25 and two support beams 26. The section of the slide
track 25 can be designed to be circular, quadrate, flute-shaped,
protrudend, or I-shaped. The instant embodiment chooses circle as
the section of the slide track 25.
[0021] Referring to FIG. 6 simultaneously, the second shelf-board
31 of the secondary article support 3 provides a pair of limiting
beams 33, whose length L is smaller than the distance H between the
support beam 26 of the track bracket 23 of the primary article
support rack 2 and the first rail 27 of the first shelf-board 21.
The length of the support beam 26 is larger than the distance
between the two limiting beams 33, and the distance between the two
limiting beams 33 is larger than that between the two slide tracks
25. The limiting beams 33 can limit the secondary article support
rack 3 in right and left direction when sliding the secondary
article support rack 3 relative to the primary article support rack
2 and define a maximum extension position of the secondary article
support rack 3 when extending the secondary article support rack
3.
[0022] As shown in FIG. 7, one end of the clamp 4 forms a first
split ring 41, and the other end forms a second split ring 42 and a
third split ring 43 which are symmetrical and have opposite splits.
The inner diameter of the first split ring 41 is larger than the
outer diameter of the first rail 27 of the primary article support
rack 2, the inner diameter of the second split ring 42 is larger
than the outer diameter of the second rail 34, and the inner
diameter of the third split ring 43 is larger than the outer
diameter of the third rail 35 so that the split rings 41-43 can
buckle on the corresponding rails 27, 34 and 35, which will be
described in detail hereinafter.
[0023] The assembling of the article support rack of the present
invention is as followed.
[0024] Referring to FIG. 2 and FIG. 3, make the secondary article
support rack 3 face to the primary article support rack 2 and
slightly hold up the opening end of the secondary article support
rack 3, hitch the limiting beams 33 of the secondary article
support rack 3 to the track bracket 23 of the primary article
support rack 2, then push the secondary article support rack 3 into
the primary article support rack 2.
[0025] As shown in FIG. 8, the first split ring 41 of the clamp 4
buckles on the first rail 27 of the first shelf-board 21 of the
primary article support rack 2, and the clamp 4 can rotate against
the first rail 27 of the primary article support rack 2.
[0026] In normal state when there is no need for the secondary
article support rack 3, the secondary article support rack 3 is
telescoped inside the primary article support rack 2 and the second
split ring 42 of the clamp 4 is buckled on the second rail 34 of
the second shelf-board 31 of the secondary article support rack 3
(referring to FIG. 3) so that the primary article support rack 2
and the secondary article support rack 3 are fixed relatively. In
this state, the room space occupied by the article support rack 1
is almost equal to the volume of the primary article support rack
2.
[0027] When the users want the article support rack to place more
objects, they can unfasten the second split ring 42 of the clamp 4
from the second rail 34 of the second shelf-board 31 of the
secondary article support rack 3, then pull the secondary article
support rack 3 out of the primary article support rack 2, and then
buckle the third split ring 43 of the clamp 4 on the rail 35 of the
second shelf-board 31 of the secondary article support rack 3 so
that the primary article support rack 2 and the secondary article
support rack 3 are relatively fixed (referring to FIG. 8). In this
state, the secondary article support rack 3 is extended so as to
increase the space for placing more objects. When the users do not
want the article support rack to place more objects, they only need
to unfasten the third split ring 43 of the clamp 4 from the third
rail 35 of the second shelf-board 31 of the secondary article
support rack 3, then push the secondary article support rack 3 into
the primary article support rack 2 again and buckle the second
split ring 42 of the clamp 4 on the second rail 34 of the second
shelf-board 31 of the secondary article support rack 3 so that the
primary article support rack 2 and the secondary article support
rack 3 are relatively fixed. So the room space occupied by the
article support rack 1 is the same as that occupied by the primary
article support rack 2 again.
[0028] It should be noted that:
[0029] (1) More other rails 36, 37, 38 can be provided on the
secondary article support rack 3 (referring to FIG. 5) besides the
second and the third rails 34, 35. When the user only needs to pull
partial secondary article support rack out, the second and third
split rings 42, 43 of the clamp 4 can buckle on the corresponding
rails at a certain place. That is, the user can freely adjust the
article support rack via extending or telescoping the secondary
article support rack to a position within the maximum stretch
position depending on the quantity of objects to be placed, thereby
do not waste room space.
[0030] (2) The quantity of the shelf-board of the primary and the
secondary article support racks 2, 3 are not limited. Referring to
FIG. 2, the primary and the secondary article support racks 2, 3
both are designed to be multilayer structure with several
shelf-boards 29, 39.
[0031] (3) The slide guiding device disposed between the primary
article support rack 2 and the secondary article support rack 3 is
not limited to the abovementioned solution, it can be achieved by a
traditional pulley module for drawer, that is, mounting the slide
track and the slider of the pulley module to the primary article
support rack 2 and the secondary article support rack 3
respectively so as to realize their relative slide.
[0032] (4) The secondary article support rack 3 can be telescoped
into the primary article support rack 2 from its left side or right
side freely. Therefore the assembling direction is not confined to
a certain direction, and the assembling is flexible and
convenient.
[0033] (5) The split rings 41-43 of the clamp 4 may have the same
inner diameter, and also may have different inner diameter. The
sizes of the inner diameters of the split rings 41-43 depend on the
sizes of the outer diameters of the respective rails 27, 34,
35.
[0034] As indicated above, in comparison with the traditional
article support rack, the advantage of the present invention is
that the article support rack of the present invention not only can
be extended to meet the user's requirement of placing more objects,
but also can be telescoped to avoid wasting room space when there
is no need for placing more objects.
[0035] Thus, the present invention provides, in various
embodiments, an improved article support rack. The foregoing
