BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention is related to a rack for office machines. Such rack 
for office machines is composed of a plurality of rods of different 
lengths, a plurality of feet and seals insertably mounted respectively on 
a bottom plate and a plurality of intermediate plates. These members are 
combined at will to construct the rack. 
2. Description of the Prior Art 
It is very popular to use office machines in a modern office. Space in such 
modern offices changes a lot by entering of such office machines. With a 
view on managing, to integrate or arrange office machines of different 
usage efficiently in an identical location should be the best mode for 
increasing working efficiency. Therefore, multifunctional racks for office 
machines in the market are specifically welcome. 
Racks for office machines in the market nowadays are mostly provided with 
the function of gathering the office machines for management. However, 
such racks are mostly sold in a certain combination, the function they 
provide is certain and unchangeable, a user can only use such a rack for 
some office machines that the rack more likely suits concerning their 
sizes and types. Hence there is often uneasy operation of the office 
machines and the case that viewing is obstructed. These are contrary to 
the original purpose of using the rack. 
SUMMARY OF THE INVENTION 
The reason that such racks mostly do not fit the sizes of office machines 
and therefore do not provide suitable operation spaces for the latter is 
resided in that, such racks lack of a factor of flexible combination. In 
view of this, the present invention provides a rack adapted to be freely 
combined and changed to a variety of forms. The present invention is 
comprised of a bottom plate, a plurality of intermediate plates, feet, 
rods and seals. A plurality of holes are provided at appropriate locations 
on the bottom plate and intermediate plates. The feet, rods and seals are 
provided respectively with ends with internal or external threads. These 
ends are inserted respectively into the holes on the bottom plate and 
intermediate plates to pile up the bottom plate and intermediate plates in 
layers. By different lengths of the rods, spaces of different height can 
be created on the rack. The intermediate plates can have various suitable 
shapes to form most suitable shelving spaces. With this arrangement, the 
present invention can solve the problem that conventional racks for office 
machines are mostly unchangeable in space utilizing. 
The present invention will be apparent after reading the detailed 
description of the preferred embodiment thereof in reference to the 
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, the present invention is comprised of a bottom plate 
1, a plurality of intermediate plates 2, feet 4, seals 5 and rods 6. 
Wherein, the bottom plate 1 and the intermediate plates 2 are provided at 
appropriate locations thereon with plurality of holes 10, 20. Each foot 4 
is provided on one end 40 thereof with an internal thread. Each seal 5 has 
a flanged top 50 and an opposite end 51 with an external thread. Each rod 
6 is provided on one end 60 thereof with an internal thread and on the 
other end 61 thereof with an external thread. 
Referring to FIG. 2, the rods 6 of the present invention can be of various 
lengths optionally. As depicted in the drawing, the mode of combination of 
the present invention is in the way below: The ends 40 with internal 
threads of the feet 4 are each inserted into a hole 10 on the bottom plate 
1. Then one of the rods 6 with suitable length is selected to have its end 
61 with an external thread engaged with the end 40 with an internal thread 
of the one of the feet 4. The other end 60 of the rod 6 with the internal 
thread is inserted into the hole 20 on one of the intermediate plates 2. 
In addition to the above stated steps and in constructing a rack with 
multiple layers, an end 61A of another rod 6A of suitable length and with 
an external thread is threadedly engaged with the internal thread of the 
above stated end 60 of each rod 6. And lastly, the ends 51 with external 
threads of a plurality of seals 5 are respectively thradedly inserted into 
a plurality of ends 60A having internal threads of the rods 6A in the 
holes of the uppermost intermediate plate 2A. Then the holes are sealed 
with the flanged tops 50 of the seals 5. 
Referring to FIG. 3 showing the structure of another embodiment of the 
present invention, wherein, a plurality of rods 7 are composed of several 
separated members. As shown in the drawing, each rod 7 is provided with a 
main shank 70 and a cap 71. Wherein, The main shank 70 is provided with 
two ends 700, 701 with external threads of different diameters. The lower 
portion of the end 701 with the external thread of the larger diameter 
adjoins a flange 702. The cap 71 is provided with two internal threads 
710, 711 in two stepped parts thereof. The end 700 with an external thread 
of the rod 7, is similarly threadedly inserted into end 40 of a foot 4, 
which has an internal thread a bottom plate 1 is assembled to an 
intermediate plate 2. While the other end 701 with an external thread of 
the larger diameter is threadedly engaged with the internal threads 710 
having also a larger diameter on the cap 71. The rod 7 being threadedly 
engaged is then inserted with its internal thread 711 having a smaller 
diameter into a hole on the intermediate plate 2. A seal 5 is screwed in 
the internal thread 711 having a smaller diameter onto the cap 71. Such 
rod 7 is for the purpose of utilizing the main shank 70 being of the 
various ones with different diameters and the cap 71 thereof to create a 
solid rod 7, and to render the rack composed of a plurality of rods 7 to 
have a solid visual effect. 
Referring to FIG. 4 showing the structure of a further embodiment of 
present invention, wherein, a plurality of rods 8 are composed of a main 
shank 80, a cap 81 and a collar 82. The main shank 80 is also provided 
with ends 800, 801 with external threads of larger and smaller diameters 
respectively. The cap 81 is also provided with two internal threads 810, 
811 in two stepped parts thereof. The collar 82 has a peripheral rim 820 
protruding upright upwardly and downwardly. Such rod 8 similarly has its 
end 800 with a smaller external thread threadedly inserted into the end 
40A with an internal thread of a foot 4A. While the collar 82 is first 
inserted into end 801 with a larger external thread of the main shank 80, 
then the end 801 is threadedly engaged with the larger internal threads 
810 on the cap 81. The internal thread 811 having a smaller diameter of 
the cap 81 is inserted into a hole on the intermediate plate 2. A seal 5 
is screwed in the internal thread 811 having the smaller diameter. Such 
rod 8 is for the purpose to solve the problems as shown in FIG. 3, 
wherein, the main shank 70 and cap 71 of the rod 7 leave a seam between 
the cap 71 and the flange 702 of the main shank 70 after threaded engaging 
thereof. The seam is obscured with the thicker portions 820 on both ends 
of the collar 82. 
Referring to FIGS. 5 and 6, the present invention can form any type of rack 
suiting any type of office machine by combination of rods of various types 
and bottom plate as well as intermediate plates of various shapes. As is 
depicted in FIG. 5, an elementary rack for an office machine is combined 
by a bottom plate 1, a frame 9 having the same function as an intermediate 
plate, a plurality of feet 4, seals 5 and rods 7. FIG. 6 shows a rack 
constructed by taking the rack of FIG. 5 as a basic structure and suiting 
various office machines used together on the rack. The rack is combined by 
a plurality of bottom plates 1 with various shapes, a plurality of 
intermediate plates 2A, 2B, 2C, and a plurality of feet 4, seals 5 and 
rods 7 of various lengths. 
In conclusion, the present invention provides a rack for office machines. 
The device can get the object of flexible combination and abundant 
variation in suiting various requirement of usage. The structure stated 
above is only for illustrating a preferred embodiment of the present 
invention, and not for giving any limitation to the scope of the present 
invention. It will be apparent to those skilled in this art that various 
modifications or changes can be made to the elements of the present 
invention without departing from the spirit, scope and characteristic of 
this invention. Accordingly, all such modifications and changes also fall 
within the scope of the appended claims and are intended to form part of 
this invention.
