ASSEMBLED TABLE CARRIAGE
Abstract
The present invention provides an assembled table carriage,
including a vertical support and at least a grounding support. The
grounding support is exposed transversely at the periphery of the
vertical support, where a mating end and a protruding end are
formed. An axial groove and axial rib are mated between the
periphery of vertical support and the mating end of the grounding
support, thus enabling the grounding support to be slid axially via
the mated axial groove and axial rib and also positioned via a
spacer. The shelving unit can be embedded into the vertical support
for axial sliding, allowing to adjust the height of table with
greater convenience and applicability.

[0001] Not applicable.

[0002] Not applicable.
NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT
[0003] Not applicable.
REFERENCE TO AN APPENDIX SUBMITTED ON COMPACT DISC
[0004] Not applicable.
BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates generally to a carriage
structure, and more particularly to an innovative carriage that is
an assembled structure for tables.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0008] A table is generally supported by a carriage, under which
several legs are arranged to support the table collaboratively in a
balanced state. Moreover, the carriage is set at a fixed height,
and the legs are fixed on the bottom of the carriage for a fixed
height of table. However, there are shortcomings are observed
during actual application.
[0009] For example, the table cannot be adjusted depending on the
stature of the users, leading possibly to fatigue or ache of the
users or inconvenience of operation.
[0010] Also, as the table legs are fixed onto the bottom of the
carriage, the table cannot be erected uprightly and stably if any
leg is damaged or broken, so the entire table has to be discarded,
resulting in a waste of resources.
[0011] Furthermore, the table legs of the same dimension are fixed
onto the bottom of the carriage, so the shapes of legs cannot be
adjusted where necessary.
[0012] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve efficacy.
[0013] Therefore, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0014] There is enhanced efficacy of the present invention.
[0015] The grounding supports are individually prefabricated with
strong enough structural strength, so they can be axially shifted
or removed/assembled independently of the vertical support, so as
to meet the user demands where necessary.
[0016] An axial groove and axial rib are arranged around the
vertical support, such that the shelving unit can be embedded into
the vertical support for axial sliding, allowing to adjust the
height of table with greater convenience and applicability.
[0017] As the grounding supports can be assembled and disassembled
independently, a variety of grounding supports can be generated and
selected to meet the diversified user demands.
[0018] There are improvements brought about by this invention.
[0019] In the case where the scale is set on the periphery of the
vertical support, users can adjust the grounding supports to the
same height in reference to the scale T, making it possible to
adjust them more conveniently and accurately.
[0020] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0026] FIGS. 1-5 depict preferred embodiments of an assembled table
carriage of the present invention. The embodiments are provided for
only explanatory purposes with respect to the patent claims.
[0027] Referring first to FIGS. 1-4, the carriage A comprises a
vertical support 10 and at least a grounding support 20. The
vertical support 10 is a hollow extruded tube, at bottom of which a
hollow chassis 13 is screwed by bolts 14. Several grounding
supports 20 can be separately assembled around the vertical support
10 in a radiative state. The grounding support 20 is exposed
transversely at the periphery of the vertical support 10, where a
mating end 21 and a protruding end 22 are formed. An axial groove
11 and axial rib 12 are mated between the periphery of vertical
support 10 and the mating end 21 of the grounding support 20, thus
enabling the grounding support 20 to be slid axially via the mated
axial groove 11 and axial rib 12, and also positioned via a spacer
30.
[0028] The spacer 30 is composed of at least a clamping wedge 31
and a bolt 32. The mating end 21 of the grounding support 20 is
provided with a chamber 211 for assembly of the clamping wedge 31.
An oblique surface 311 is arranged between the clamping wedge 31
and the chamber 211. When the clamping wedge 31 is screwed by the
bolt 32, the oblique surface 311 of the chamber 211 is supported by
the oblique surface 311 of the clamping wedge 31, allowing the
mating end of the grounding support 20 and the vertical support 10
to be positioned securely. An embedding portion can be arranged
between the clamping wedge 31 and the periphery of the vertical
support 10.
[0029] Based on above-specified structures, the present invention
is operated as follows:
[0030] Referring to FIG. 5, the grounding supports 20 are
individually prefabricated. When it is intended for adjusting the
height of the grounding supports 20, users can adjust them to the
same scale T set on the periphery of the vertical supports 10, thus
making the table stable without any inclination.
