CORNER CONSTRUCTION
Thls lnvention relates in general to ~oint
structures and, more particularly, to a corner
construction.
It is an obJect of the present invention to
5 provide a corner construction especially suitable
for utillzation with furnitureg display flxtures,
storage equlpment, and the like~ which integrates in
a novel, yet highly st~ble fashion, structural or frame-
forming components of the article in question.
It is another ob~ect of the present inventlon
to provide a corner const:ruction of the character
states which especially suitable for formation ~rom
tubular components, permitting of ease of assembly
into a stable Joint which is resistant to disassembly
15 in use; but which may be intentionally disassembled
in a faclle, rapld manner.
It is a further ob~ect of the present inventlon
to provide a corner con~truction o~ the charac~er
stated which allows ~or a unique integration o~
20 8tructural component3 o~ the particular artlole
without requiring the services of skilled personnel
and which obviates the necessity for complex tools
for assembly; as a simple and conventlonal tool is
sufflcient.
It ls a still further obJect to the present
inventlon to provide a corner construction as lndicated
above, which is most durable and reliable in usage;
which is economlcal in production~ and whlch is of
marked versatility in utllization. Another property
30 of this invention is no screw is necessary in any
connection of those tubes.
The invention will now be descrlbed by way of
example with reference to the accompanylng drawlng ln
which:-

A designates a table which is set Yorth for
exemplary purposes only, being but one Or myrlad
structures with which the present lnventlon may be
utillzed.
Figure 1 shows one of the examples Joint
connectlon invented. through outer or external view,
via vertlcal tube 19 square tube 2 and table top 4.
Through ~oint connection of all parts mentioned above~
corner construction ls made. Figure 2 shows that
cublc section of the connection especlally corner o~
the Figure 1 the property of the invention is that in
each recess no matter if its lateral or transversial
tube 2 & 3 and 1, one the edge o~ the tube 1OJ 20, 309
9;~:
on their recess edge 13, 21, 313 through sawing or
cutting methods, establish a suitable slots 11, their
wldth and depth should be suitable for the connection
purposes, and also recess of a, 11, b, L type which
5 are numbered as 22 and 32 on each vertical tube 1 body
10, connecting parts of both recess edge with degree
of 90 establish saw type recess lla and llb, and on
the edge of saw type recess lla and llb opening 12 is
made. Its thickness is tube thickness ~ table top 4
10 thickness so that after those lateral tube 2 are
connected, then table top 4 i8 going to be rixed. In
this case~ each corner of the board may not be cut off
and on the contrary be inserted into the body of the
tube 10, one fourth 50 that the boards can be easlly
15 flxed.
On the lateral tube body 2, in each tube body's
20 recess edge 21 on any side either upper or lower
side, saw type recess 22, no other opening or embossing
is necessary. Connecting ~oint 5, and chocking ~oint
20 6, please refer figure 3, 4 and 5, basically composed
of a ~oint 51 with corrugated surface 54 extended
downward through Joint 53c, its shape is similar to
that of 52 and on C on its similar to 52 side, establish
a 90 degree openlng 55 so that wh:lle assemblying with
25 board the section of its corner may be avoided. As
illustrated in Figure 5, the constructlon of chocking
Joint 6 basically similar to that o~ connecting ~oint
5, establish platform 60 and no ~oint with corrugated
surfaces are establlshed. On C type tube 61 to cope
30 with the assembly position of lateral tube 2~ 3, prepare
recess of 62 and 63.
The sidth of the recess lla and llb o~ the
vertical tube, should be same with the thickness of
lateral tube material. The L typed recess 22 and 32
of the lateral tube 23 3, their thlckness should be
the same wlth the thickness of the vertical material
of the vertical tube. Thus the connecting effectiveness
may be better.
While assemblying each part of the invention~ all
the things we have to do is that to pu-t recess edge 2 of
the lateral tube 2 is L typed recess 22 and 32 into saw
typed recess of lla and llb of the vertical tube 1, and
rlx table top 4 or other similar board and then connecting
10 ~olnt 5 should be inserted from vertical direction i.e.
from upper direction of the vertical tube 1, to be inserted
into vertical tube exactly. Thu~ each lateral tube 2
and 3 can be well fixed with those vertical tubes 1. with
very correct 90 degree angle, and ~urthermoreJ through
15 applying table top 4's assembly, we can obtain even more
firm connectlon that there wlll be dropping occur and
through using upper ~oint of the 51, o~ the connecting
~oint 5 appropriake length of vertical tube 1 can be
connected to them in case of necessity~ the height of
20 the table can be promoted. On the upper edge of the
vertical tube 1 put on chocking ~oint 6 then in a short
period of time, multi-layered cargo shelf can be assembled.
From the foregoing it will be readily seen that
the corner construction Or the present invention may be
25 easily developed without the services of a skilled
individual. Consequently, this invention is adapted
for utillzation with knock-down furniture, fixtures, a~d
the like. As brought out above, table is merely illustra-
tive of but a single application of the present invention
30 since it is readily useful in all types of furniture,
such as bookcases~ chairs, and the like, as well as for
display and storage fixtures such as shelving, etc.
Table top may be of any desired material such as wood,
glass and the llks.
If longer and sider shelves are planning to be
established, the construction and assembly method with
vertical tube 1 are exactly the same with above when-
ever three lateral tube 23 3, 7 should be connected with
5 vertical tube 1, and forms T type, then connecting Joint
5, or chocking ~oint 53, put them on the recess of
vertical tube 1 according to the dlrections of three
lateral tube 2, 3, 7, and ad~ust them according to the
remaining space. The body of vertical tube 10 the
10 opening o~ it 12, and C typed hole 52, and its opening
55 o~ the connecting ~oint 5. All of them should be
set comparatively wider, if four lateral tubè 2 connectlng
with vertical tube ln cross type, (Please re~er to
Fi~ure 8) the shape of the ~ointer 53 o~ the connectin~
15 ~oint 5, according to those lateral tube 2', 3', 7~,
8' have connected with the recess o~ the vertical tube
1J and what remaining space is left over there~ and
ad~ustment will be made thereafter.
Separated 4 ~oint 53 are set, and no C typed hole
20 52 is established ak the opening of the verti~al tube 10,
a number of saw typed recess lla, llb, and llc are set.
No other opening is necessary. When ~able top 4~ or
other board are going to be set on the cross typed recess
cut those corner or make it become same shape with
25 vertical tube body lO and according to the method mentioned
above, we can make vertical tubes a s~uare ones to
replace these round ones.
