[0001] This Application corresponds to one filed Jun. 14, 2006, as
PCT/CN/2006/001318.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Research and development of this invention and Application
have not been federally sponsored, and no rights are given under
any Federal program.
REFERENCE TO A MICROFICHE APPENDIX
[0003] Not Applicable
BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] This invention relates to chair structures, in general, and
to one that might be generally termed a "Barstool" as a high seat
chair, in particular.
[0006] 2. Description of the Related Art
[0007] One of the problems associated with a typical design for
these types of chairs is that its volume and height make it
difficult to transport over long distances. This follows from the
fact that these chairs are typically manufactured as an integral,
one-piece high seated structure. Separating the chair-seat portion
from the base portion to facilitate transportation as separate
items proves somewhat problematical as it is very troublesome to
try to screw them together after delivery.
[0008] Obviously, an improved structure would be desirable so as to
allow a convenience in transportation and an ease in
installation.
SUMMARY OF THE INVENTION
[0009] As will become clear from the following description, the
barstool-type chair structure of the first two embodiments of the
present invention allows for the simple fitting of one upon the
other at the point of delivery, just by putting the base portion on
the floor and positioning the chair-seat portion onto it in place.
To facilitate the installation, a first frame manufactured in the
bottom of the chair-seat portion and a second frame manufactured in
the top of the base portion include correspondingly placed
male-member connectors and female-member sockets between the two of
them to allow the fitting of one set into the other.
[0010] The third and fourth embodiments of the present invention
employ a similar connecting concept, but in an arrangement which
allows the chair-seat portion of the barstool chair to rotate from
side to side with respect to the base portion. With the first two
embodiments, once the chair-seat portion is positioned onto the
base portion, the seat-portion is fixed in place.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] These and other features of the present invention will be
more clearly understood from a consideration of the following
description, taken in connection with the accompanying drawings, in
which:
[0012] FIGS. 1-3 and 4-5 are pictorial drawings helpful in an
understanding of the first and second embodiments of the invention,
respectively;
[0013] FIGS. 6 and 7 are pictorial drawings respectively helpful in
an understanding of the third and fourth embodiments; and
[0014] FIG. 8 is a schematic diagram, partially in sectional view
helpful in an understanding of the way in which the seat and base
portions of the barstool may be secured together.
DETAILED DESCRIPTION OF THE INVENTION
[0015] The barstool-type chair of FIGS. 1-5 includes a chair-seat
or main-body portion 1 separated from a base portion 2, but to be
connected at a point where delivery and installation are to be
made. In accordance with the invention, male-member and
female-member connectors are to be placed between the two portions
in joining them together. Essentially, the male-member connectors
consist of linearly extending petaline assemblies, the
female-member connectors consist of socket receiver assemblies, and
inserting joints secure the two assemblies together.
[0016] As shown in FIG. 1, a first fixing frame 6 is secured on the
base portion of the chair with upwardly extending connectors 3
integrally formed with it. A second fixing frame 7 is similarly
secured on the underside of the chair-seat or main-body portion 1
(FIG. 2), with downwardly extending sockets 8 to receive the
connectors 3. FIG. 3 illustrates how a petaline arrangement of
connectors 3--and particularly the intersecting joint 5 molded at
the top of each assembly--fits within the socket 8 in flexibly
connecting with a step 9 for setting the joint 5 in place.
[0017] In accordance with the embodiment of FIGS. 1-3,--the fixing
frame 6 is manufactured in the form of a large plus sign "+" at the
top of the base portion 2, the fixing frame 7 is similarly
manufactured in the form of a large plus sign "+", but at the
bottom of the chair-seat portion 1, and the sockets 8 are fixed in
opposition to the connectors 3. The barstool-type chair, or like
chair designed in this manner, can be separated into its two
component sections for packing in a manner to ease its shipment.
The subsequent installation and setting up of the chair would be
simple and convenient, by fitting the sockets 8 over the connectors
3.
[0018] The barstool-type chair of FIGS. 4 and 5 will be seen to be
simply the reverse of that of FIGS. 1-3 in the placements of the
sockets 8 and the inserting connectors 3 along with their fixed
frames. In FIG. 4, the fixed frame 7 and sockets 8 are secured with
base portion 2, while the fixed frame 6 and inserting connectors 3
extend downwardly from the underside of the chair-seat, main-body
portion 1. As with the construction of FIGS. 1-3, the sockets 8 are
fixed in opposition to the inserting connectors 3 for joining the
seat and the base together. As will be seen, the large plus "+"
fixing frames 6 and 7 are respectively positioned with the top of
the base portion 2 and bottom of the chair-seat portion 1 to ensure
proper alignment of the interconnect.
[0019] Whereas the embodiments of FIGS. 1-3 and 4-5 fix the
chair-seat portion 1 with the base portion 2, the embodiments of
FIGS. 6 and 7 allow for a rotation of the chair-seat, main-body
portion 1 with respect to the base portion 2. Referring to FIG. 6,
for example, a connecting plate 10 is secured on the base portion 2
of the chair, provided with the upwardly extending connectors 3 at
its four corners. A connecting plate 11, on the other hand, is
secured on the underside of the chair-seat portion 1, along with a
turnplate 12 secured on the bottom of the connecting plate 11. The
sockets 8, here, are molded on the turnplate 12, again in
opposition to the connectors 3 joining together the two plates 10
and 11. The turnplate 12 allows the chair-seat portion 1 to be
rotated with respect to the base portion 2--while at the same time,
offering the advantage of convenient packaging for transportation
and subsequent installation, as do the first two embodiments of the
invention.
[0020] With the operation of the FIG. 6 embodiment being thus
understood, the embodiment of FIG. 7 will be seen to follow
directly. In FIG. 7, the connecting plate 10 and the connectors 3
are secured with the underside of the chair-seat, main-body portion
1, and the connecting plate 11 and the turnplate 12 are secured at
the top of the base portion 2. Again, the sockets 8 are molded on
the turnplate 12 in opposition to the connectors 3 to fit the
insertion of the connectors 3 with the sockets 8 and allow the
chair-seat portion 1 to rotate with respect to the base portion
2.
[0021] FIG. 8 illustrates how the chair-seat portion 1 may be
further secured with the base portion 2. Specifically, a keyhole 13
is shown adjacent an upper side of the main-body of the inserting
connector 3, to receive a key 14 inserted through a passage of the
chair-seat main-body portion 1. As will be appreciated, this can be
done with any one or groups of the inserting connectors to further
stabilize the barstool-type chair, and serves to further connect
the chair-seat and base portions together.
[0022] While there have been described what are considered to be
preferred embodiments of the present invention, it will be readily
appreciated that modifications can be made by those skilled in the
art that without departing from the scope of the teachings herein
of first separating the seat and base portions of a chair so as to
facilitate ease of transportation, and so as to later allow a
convenient joining of the two together at their destined location
simply through the alignment of oppositely positioned male and
female interconnecting members. For at least such reason,
therefore, resort should be had to the claims appended hereto for a
true understanding of the invention.
