Structure room divider height extension

The invention relates to a room divider height extension, specifically referring to a kind installed onto an existent lower room divider to increase the original height, with three inverted-U shaped support tabs welded along the bottom edge. Furthermore, there are semicircular tabs protruding from the lower edge of the left and right aforesaid support tabs that are inserted into the U-shaped slots along the upper edge of the existent room divider, and when the room divider height extension and the existent room divider are firmly assembled together, a square tunnel is formed for the placement of electric power lines, telephone lines, computer cables within the improved structure, all of which comprise the primary innovations of the invention herein.

BACKGROUND OF THE INVENTION 
The invention here consists of an improved structure room divider height 
extension, specifically referring to a kind installed onto an existent 
lower room divider to increase the original height, with three inverted-U 
shaped support tabs welded along the bottom edge. Furthermore, there are 
semicircular tabs protruding from the lower edge of the left and right 
aforesaid support tabs of the aforesaid room divider height extension that 
are inserted into the U-shaped slots along the upper edge of the existent 
room divider, and when the room divider height extension and the existent 
room divider are firmly assembled together, a square tunnel is formed for 
the placement of electric power lines, telephone lines, computer cables 
within the improved structure. 
Conventional office-use room dividers are available in various 
specifications, with heights including 1000H, 1200H, 1350H, 1500H and 
1800H. However, each different height has a varying range of intervals. 
For example, in an open office environment, a room divider system 1,000 mm 
in height can be installed as interior partitioning without difficulty; a 
room divider system 1,200 mm in height offers more privacy and better 
concentration efficiency; a room divider system 1,500 mm in height offers 
a separated and focused working environment; and a room divider system 
1,800 mm in height offers an independent working environment. Therefore, 
different height room dividers provide for various kinds of working 
environment. However, after a planned room divider system is constructed 
in most business offices, it is impossible to raise or lower the height 
and modifying the height of the existent room divider would require total 
reconstruction and an extensive renovation project resulting is great 
waste of materials and major inconvenience; in the active height 
adjustment mechanism of a conventional structure room divider extension, 
as indicated in FIG. 1, the room divider height extension (10) is 
installed on the existent room divider (12) and on each of the two lower 
sides of the room divider extension (10) is a round insertion pin (11) and 
the insertion pins (11) are inserted into the insertion pin holes (14) at 
both ends of the U-shaped slot (13) to attain the objective of a firmly 
installable room divider height extension. However, although a tunnel for 
the hidden installation of electric power lines, telephone lines and 
computer cable circuit system is designed into the conventional room 
divider height extension structure, the originally installed line/cabling 
channel may be obstructed by the insertion of the room divider height 
extension (10) pins (11) and forcing the assembly of the room divider 
extension (10) will crush the originally installed line/cabling and 
adversely affect the operation of the circuit system. 
As a result, the improvement of the aforementioned room divider height 
extension design problems in overall modem office planning as well as 
striving for a more ideal and practical design have become major 
objectives. The invention herein has overcome the problems of conventional 
room divider height extensions through extensive research in a spirit of 
continuous effort involving three prototypes and related improvements, 
culminating in the research and development of a kind of improved 
structure room divider height extension that genuinely solves the 
shortcomings of the conventional product. 
Therefore, the primary objective of the invention herein is to provide a 
kind of improved structure room divider height extension, the utilization 
of which economizes on the materials and labor required to modify an 
existent room divider and thereby increases the practical value of the 
improved structure room divider extension invention herein. 
To enable the examination committee to acquire a full understanding of the 
structure and content of the invention herein, the following brief 
descriptions of the drawings and detailed description of the invention 
herein are attached to illustrate the advantages and innovativeness. 
However, the following descriptions of the preferred embodiment shall not 
be construed as limitations outside the claims of the invention herein, 
including related modifications such as changes in the number and the 
nature of the components, but shall be remain within the rightful claims 
of the invention herein.

DETAILED DESCRIPTION OF THE INVENTION 
First, as indicated in FIG. 2, the invention herein is comprised of a room 
divider height extension (20) that has three inverted-U shaped support 
tabs (21), (21) and (24) welded to the lower edge, and protruding from the 
lower edges of the support tabs (21) are four semicircular tabs (211) that 
are inserted into the square holes (221) inside the U-shaped slots (23) of 
the existent room divider. Furthermore, the support tabs (21) and the 
slots (23) when inserted together form a square line/cable tunnel (212), 
wherein the aforesaid tunnel can accommodate the installation of electric 
power line(s) (25) (or telephone lines, computer cables and so on) through 
openings (26) on two sides of the tunnel (212). Each room divider height 
extension (20) has three support tabs (21), (21) and (24). Making it is 
easy to maintain an even contact between the matching surfaces after the 
room divider extension (20) and the existent room divider (22) are 
assembled together as opposed to the results depicted in FIG. 1 of the 
conventional product, wherein the room divider extension (10) is often 
slanted forward or rearward in appearance and function due to the method 
of assembly. 
As indicated in FIG. 3 and FIG. 4, the two sides of the support tabs (21) 
of the invention herein are slanted inwards at slight angle to facilitate 
height adjustment during the installation process. As indicated in the 
drawings, the line/cable tunnel (212) formed through the assembly of the 
support tabs (21) to the existent room divider (22) can accommodate the 
installation of line and cable circuit systems. 
Based on the foregoing description, the invention herein constitutes an 
improvement of the conventional product and, in terms of application, is 
the first innovation of its kind within the same product category. The 
invention herein has more enhanced practical functions and unquestionable 
"originality"; thereby attaining all the objectives claimed by the 
invention herein and complying with the conditions of "practicality" 
required for patent rights and in accordance thereof, the application for 
patent rights based on the "originality" of the invention herein is hereby 
submitted for examination and the granting of the respective patent 
rights.
