Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to an improved side frame for
a loading plane of tables and chairs and particularly a side frame
capable of assembling and fastening loading members to support
loading of human body and goods.
[0002] Many known leisured chairs now available on the market have
loading planes (seat pads or backrests) made of metal tubes or
wooden beams coupling with fabrics or leather. During fabrication,
the fabrics or leather are cut to the sizes of desired loading
planes. The cut fabrics and leather are stitched on the rims to
form coupling sections. Then metal tubes or wooden beams of
selected sizes and lengths are disposed into the coupling sections
to form loading planes for supporting people and goods. There are
some other types which have stitched binding rims formed on the
fabrics or leather. Then a plurality of apertures are formed on the
binding rims to engage with spring hooks which are in turn fastened
to metal tubes or wooden beams.
[0003] The leisured chairs set forth above require a lot of
processes and time in production and assembly. They are also
difficult to fabricate. After using for a period of time, the
stitching of the fabrics or leather could be frayed or ruptured, or
the springs connecting the fabrics (or leather) and metal tubes or
wooden beams could have material fatigue, or the metal tubes or
wooden beams will result in deformation. All this could cause
undesirable using conditions or even hazards.
[0004] In order to remedy aforesaid problems, there are other
loading planes for leisured tables and chairs being developed and
introduced. One of the examples is to form a frame made of metal
tubes (or bars) to support the loading plane, then fasten a
plurality of loading elements (plate forms) made of metal or wood
to the frame. While such a construction is stronger and more
durable for supporting human weight or goods, it takes more work
and time to produce and assemble. Moreover, after assembly of the
products is finished, a lot of screws will be exposed. It is not
sightly and is easy to injure users. The fastenings between the
loading elements and frame could get loose after using for a period
of time, and could cause injury to users. Moreover, the fastenings
must be done by means of tools in a fixed and tight manner. It is
not convenient for users to use.
SUMMARY OF THE INVENTION
[0005] The primary object of the invention is to resolve the
foregoing disadvantages. The invention aims to provide an assembly
type frame to couple with loading members for use in tables and
chairs.
[0006] Another object of the invention is to provide an assembly
type frame to couple with loading members for assembling loading
planes of tables and chairs with least possible processes and
time.
[0007] A further object of the invention is to provide a loading
plane that has no exposed screws or fasteners after assembled to
enhance total appealing of the finished products and avoid hurting
users.
[0008] To attain the foregoing objects, the frame of the invention
includes a loading section which has one end extended to form an
extended section which in turn connects an eave section. The eave
section and the loading section form an anchor section
therebetween, and also have respectively a chamfer section
corresponding to each other. The loading section and chamfer
section have respectively an aperture formed thereon to receive a
fastener for fastening a last loading member to prevent other
loading members from loosening. After the fastener is engaged and
fastened, the aperture may be covered by a cap to prevent the
fastener from rusting and also to mask the fasteners from exposing
outside to make the appearance of the finished products more
sightly after assembly. The loading plane thus formed may be
adapted for use in tables and chairs to support people and
goods.
[0009] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to FIG. 1, the side frame for loading planes of
tables and chairs of the invention consists of a frame 1 and a
separator 2 located in the frame 1. Loading members (not shown in
the drawing) may be disposed in the frame 1 and spaced by the
separator 2 to form a loading plane to support people or goods.
[0017] The frame 1 may be made of, but not limited to, wood, metal
(such as steel, aluminum) or plastics. The frame 1 includes a
loading section 11 which has one end extended to form an extended
section 12 which in turn connects an eave section 13. The eave
section 13 and the loading section 11 form an anchor section 14
therebetween, and have respectively a chamfer section 15 and 16
opposing to each other. The loading section 11 and the chamfer
section 16 have respectively an aperture 111 and 161 formed thereon
corresponding to each other.
[0018] The separator 2 is made of, but not limited to, wood, metal
(such as steel, aluminum), plastics or rubber. The separator 2 is
disposed in the anchor section 14, and has a dividing section 21
which has two free ends formed respectively an indented recess 22
to engage with a loading member (not shown in the drawing), and two
jutting edges 23 and 23' formed on the upper side and lower side of
the dividing section 21 slidable in the chamfer sections 15 and
16.
[0019] Referring to FIG. 2, when to assemble the frame 1 of the
invention, dispose the separator 2 into the frame 1 by wedging the
jutting edges 23 and 23' into the chamfer sections 15 and 16, and
slide the separator 2 into the anchor section 14 of the frame 1.
The dividing section 21 may seal the slot opening of the anchor
section 14 to make the assembled products having more attractive
appearances.
[0020] Referring to FIGS. 3 and 4, when in use, loading members 4
(such as wood, metal, plastics) may be assembled on the frame 1 by
disposing in sequence the separators 2 or loading members 4
alternately in the anchor section 14 of the frame 1, and use the
indented recesses 22 and 22' at the free ends of the dividing
section 21 to engage with the end surface of the loading members 4
such that the loading members 4 will be assembled and fastened to
the frame 1 in a spaced fashion.
[0021] When assembling the frame 1 and loading members 4, the
separator 2 may be dispensed with so that the loading members 4
will contact one another closely in the frame 1 to form another
type of loading plane.
[0022] In addition, the bottom sides of the loading section 11 and
chamfer section 16 may have respectively an aperture 111 and 161
formed thereon corresponding to each other. A fastener 6 may be
allowed to pass through the aperture 111 and 161 to fasten the last
loading member 4 for preventing other loading members 4 from
loosening. After the fastener 6 is engaged, the aperture 111 may be
sealed and covered by a cap 7 to prevent the fastener 6 from
rusting, and also to mask the fastener 6 from exposing outside. The
appearances of the finished products will be more sightly and have
more appealing.
[0023] Moreover, after the frame 1 and loading members 4 are
assembled and fastened, the edges of the frame 1 may be coupled
with a bordering member 8. The bordering member 8 has a first plug
element 81 and a second plug element 82 to wedge into the anchor
section 14 and loading section 11 to smooth the edge rim of the
frame 1. The edge rim thus formed is less likely to hurt people and
can further enhance the total appearance and appealing of the
finished products.
[0024] Referring to FIG. 5 for an embodiment of the invention, the
loading member 4 has an aperture 41 engaged with a positioning
element 3. The positioning element 3 is made of, but not limited
to, wood, metal (such as steel, aluminum), plastics or rubber. When
the loading member 4 is assembled in the anchor section 14, the
positioning element 3 may couple closely with the chamfer sections
15 and 16 to prevent the loading member 4 from loosening or sliding
in the frame 1 to allow the loading member 4 be fastened firmly to
the frame 1.
[0025] Referring to FIG. 6 for another embodiment of the invention,
the loading members 4 are assembled in the frame 1 and spaced by
the separators 2 to form a loading plane 5 for a chair (or table)
to support the weights of people or goods.
[0026] Furthermore, the frame 1, separator 2 and loading member 4
may be made according to selected specifications and dimensions so
that assembly can be done quickly to save processes and time.
