Description

OFFICE FLOOR SYSTEM BACKGROUND OF THE INVENTION Field of the Invention The present invention relates in general to office floors suitable for an office automation flooring system and, more particularly, to an improved structure in such office floors for effectively and clearly accommodating complex and varieties of power lines and for providing a delightful atmosphere for no paper office equipped with varieties of electronic equipments such as a main computer, personal computers, telephones and facsimiles.

Description of the Prior Art In recent, the office buildings have been remarkably developed in both their designs for their outside appearances and their interiors as they are accounted much of their function as a center of business and life. The recent trend of office automation promotes the above development of the office buildings.

In accordance with the office automation, penciis and papers of the office are substituted with electronic equipments such as computers. An automated office is generally equipped with facsimiles for fast communication, a host computer for business management and personal computers.

In recent, the office is also equipped with LAN (Local Area Network) and video conference system, thus to become a base of transmission and reception of information. In this regard, the term of intelligent building system is used for such an office building. Particularly, the office automation is promoted by development of LAN.

The office automation is attended with layout of varieties of wires for powering the electronic equipments.

The varieties of power wires should be wired in accordance with a reasonable layout for achieving both the desired power supply and the maintenance of the wiring.

The above reasonable layout is achieved by an office flooring system which is concern with the present invention.

In the prior art, such an office flooring for an automated office may be achieved by a floor duct system.

However, the conventional floor duct system has a problem in that it should be limited in the wiring capacity. Another problem of the above floor duct system is resided in that it can not allow expansion of communications network since it has some difficulty in layout for new wires. Otherwise stated, the above floor duct system can not cope with the changed layout.

Alternatively, the wires may be buried in the floors of the building. However, this wiring method results in thickening of the floors of the building and shorts the height of each story of the building, thus to reduce the total area of the building.

As a further alternative, the office flooring may be achieved by an access floor system. However, the access floor system has a problem in that it uneconomically wastes the space since its height is higher than 30 cm. The height of the access floor system higher than 30 cm is inevitable because it was proposed for used in a software center. The access floor system is a fixing type system so that it can not allow the movable installation of out-let boxes. Particularly when installing integrated type out-let boxes on the access floor system, the boxes should be manufactured and assembled at the site. In addition, the above access floor system should be attended with grouting and this generates dust and increases the weight of the system. The increase of the weight of the system caused by the grouting results in overload of the building.In the above access floor system, the upper panel is simply laid on the panel support so that the panel should be distorted and generates noise such as a squeaking sound with the lapse of time.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide an office floor system in which the aforementioned problems can be overcome and which effectively and clearly accommodates complex and varieties of wires and for providing a delightful atmosphere for an automated office.

It is another object of the present invention to provide an office floor system in which the problems caused by the conventional floor duct system, the conventional access floor system and the like and which copes with the expansion of communications network and change of layout.

It is a further object of the present invention to provide an office floor system which is scarcely influenced by the height of each story of a building and remarkably reduces the load applied therefrom to the building.

In order to accomplish the above objects, an office floor system according to a preferred embodiment of the present invention comprises: a floor panel, the top surface of the panel having a plurality of bolt adjusting holes and a first opening for receiving an integrated out-let box therein, the bottom surface of the panel having reinforcing means and a plurality of bolt leading holes, the bolt leading holes communicating with the bolt adjusting holes respectively; a support unit for supporting a corner of the floor panel at the downside of the panel such that the corner of the panel is adjusted in its height at its upside so as to achieve horizontality of the panel, the panel support unit having: a plurality of holes for providing flexibility for the unit; and a plurality of inner threaded support columns; and a bolt for adjusting the height of the corner of the panel, the height adjusting bolt being received in a corresponding bolt leading hole of the panel at its slitted top part and threaded into a corresponding support column of the panel support unit at its outer threaded lower part, thus to be tightened or loosened at the upside of the panel so as to adjust the height of the corner of the panel.

In accordance with the office floor system of this invention, it is facilitated to install or remove a circular type out-let box or an integrated type out-let box.

The office floor system of this invention is suitable for accommodating both the communications network of the intelligent building system and the wiring capacity of the automated office. The office floor system of this invention is also facilitated to be installed or removed at the site and remarkably reduces its weight unlike the conventional access floor system.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which: Fig. 1 is a perspective view of an upper floor panel of an office floor system in accordance with a preferred embodiment of the present invention; Fig. 2 is a bottom view of the upper floor panel of Fig.

1; Fig. 3 is an exploded perspective view showing the coupling of a bolt leading hole of the panel of Fig. 2 to a panel support unit; Fig. 4 is a side view showing the coupling of the bolt leading hole of the panel to the panel support unit; and Fig. 5 is a perspective view showing the floor panels of Fig. 1 laid on a floor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to Fig. 1, there is shown in a perspective view an upper panel of an office floor system in accordance with a preferred embodiment of the present invention. The panel 1 is made of a steel, preferably of a gold roll steel.

The upper panel 1 is provided with an integrated type out-let box opening 2 which will receive an integrated type out-let box when the floor is practically used. The side of the opening 2 is bent into an L-shape so as to prevent its possible distortion. The upper panel 1 further includes another out-let box opening 3 which will receive a circular type out-let box. When the out-let box opening 3 receives no out-let box, it is covered with a cap 6. The cap 6 has a through hole 7 which can not pass all the wires of the circular type out-let box but passes one or two wires. The cap 6 thus still covers the out-let box opening 3 of the upper panel 1 when one or two wires are used. The upper panel 1 has four bolt adjusting holes 4 at its corners. With the holes 4, the panel can be easily adjusted in its height for maintaining the desired horizontality of the floor panels.That is, the desired horizontality of the panels 1 can be easily achieved by simply adjusting, using a screw driver, the height of a supporter 12 which will be described later herein. The integrated type out-let box opening 2 is provided with screw holes 5 for fixing the integrated type out-let box to the opening 2. When the opening 2 receives no out-let box, it is covered with a cap (not shown).

Fig. 2 is a bottom view of the panel 1 of Fig. 1. In this drawing, the bottom surface of the panel 1 is designated by the numeral 11. The bottom surface 11 of the panel 1 is provided with the cross supporter 12 for reinforcing the panel 1. The frame of the supporter 12 is flexible so that it prevents possible distortion of the panel 1. The flexibility of the supporter 12 is more profitable in reinforcing the strength of the panel 1. The mounting of the cross supporter 12 to the bottom surface 11 of the panel 1 is preferably achieved by a robot welding system. This robot welding system is profitable from the viewpoint of welding uniformity, strength reinforcement and lengthening of the using life of the product.The cross supporter 12 is provided with a plurality of small holes 13 about its center for reducing the noise of the upper panel 1, which noise may be generated when stepping on the panel 1. That is, the small holes 13 of the supporter 12 cause the resonance when the noise is generated in the upper panel 1, so that they reduces the noise. In the embodiment of Fig. 2, four pairs of small holes 13 are formed about the center of the cross supporter 12 such that they are spaced out at regular intervals. However, it should be understood that the number of the small holes 13 may be changed, that is, increased or decreased.

The free ends of the four arms of the cross supporter 12 are provided with their respective bolt leading holes 14 for receiving their bolts of the supporter 12, which bolts will be described later herein.

The bolt leading holes 14 of the supporters 12 are through holes so that the desired horizontality of the panels 1 can be easily achieved by simply adjusting the height of the supporter 12 using a screw driver at the upside of the panels 1. Each of the bolt leading holes 14 has an annular step at its middle portion which divides the hole 14 into a larger diameter lower section and a smaller diameter upper section.

The stepped portion of the hole 14 seats upwardly a stainless steel washer 27, which washer 27 will be described in conjunction with the panel support unit 21 later herein. The washer 27 not only achieves a desired insulation but also prevents a possible separation of the bolt 25 from the panel 1. The prevention of the possible separation of the bolt 25 from the panel 1 reduces of noise of the panel 1.

In Fig. 2, the reference numerals 15 and 16 denote the circular type out-let box and the integrated type out-let box received in the out-let box openings 3 and 2 of the panel 1 respectively.

Fig. 3 is an exploded perspective view showing the coupling of the bolt leading hole 14 of the cross supporter 12 to a panel support unit 21. The panel support unit 21 is used for fixedly laying the floor panels 1 on a floor of a building. In laying the panels 1 on the building floor, a support plate 22 of the unit 21 is bonded to the building floor using an adhesive such as bonding agent. After bonding the support plate 22 to the building floor, the panels 1 of this invention is fixed to the support plate 21.

The support plate 22 of the panel support unit 21 is provided with a plurality of holes 23. With the holes 23, the support plate 22 can be easily deformed or bent so as to correspond to an uneven floor of the building when the office floor system of this invention should be laid on such an uneven floor of the building. The support plate 22 is provided with four support columns 24 at its corners. The inner threaded support columns 24 receive their respective height adjusting bolts 25.

Each of the height adjusting bolts 25 generally comprises three parts, that is, an outer threaded part 25A, a head part 25B and a slitted top part 25C. The outer threaded part 25A of the bolt 25 is directly received in the inner threaded support column 24 of the support plate 21. In order to tighten or loosen the bolt 25, the bolt 25 is turned in a direction by a screw driver received in the slit of the top part 25C of the bolt 25 at the upside of the panel 1. It should be understood that the size of the height adjusting bolt 25 may be free changed in accordance with its use. That is, when it is required to use an office floor whose height is higher than 5 cm, the height of the embodiment of Fig. 3, the sizes of both the height adjusting bolt 25 and the support column 24 of the support plate 22 are changed in order to correspond to the height of the office floor.

As shown in Fig. 3, the washer 27 is received in the larger diameter lower section 14A of the bolt leading hole 14.

With reference to Figs. 1 to 3, the height adjusting bolt 25 is inserted into the bolt leading hole 14 of the supporter 12 with interposition of the washer 27. In this case, the washer 27 stably grips the height adjusting bolt 25, thus to prevent possible separation of the bolt 25 from the panel 1 and to reduce the noise of the panel 1. Here, it should be understood that the washer 27 is manufactured considering the outer diameter of the top part 25C of the bolt 25, thus to achieve the above effect.

Fig. 4 is a side view showing the coupling of the bolt leading hole 14 to the panel support unit 21. As shown in this drawing, each of the height adjusting bolt 25 which is threaded into a corresponding inner threaded support column 24 of the support plate 22 at its outer threaded part 25A is received in a bolt leading hole 14 of a corresponding panel 1 at its top part 25C. That is, each of the panel support unit 21 is placed at a cross, at which cross four panels 1 come into contact with each other, and supports four corners of those four panels 1 by its four support columns 24. After coupling the panels 1 to the panel support units 21, the height adjusting bolts 25 which are threaded into the inner threaded support columns 24 of the units 21 at their threaded parts 25A are manually handled. That is, the bolts 25 are tightened or loosened using a screw driver at the upside of the panels 1, thus to achieve the desired horizontality of the panels 1. In this case, the shank of screw driver is received in the bolt leading hole 4 of the panel 1 at the upside of the panel 1.

Fig. 5 shows the floor panels 1 of this invention laid on the building floor.

As described above, the office floor system according to the present invention overcomes the deficient wiring capacity of the conventional floor duct system and copes with the changed layout. The floor system also prevents waste of space unlike the conventional access floor system. The system is not subjected to the grouting so that it generates no dust and remarkably reduces its weight. Another advantage of the floor system of this invention is resided in that the height adjusting bolt received in the floor panel is tightly gripped by a washer received in a bolt leading hole of the panel, thus to prevent the separation of bolt from the panel and to reduce the noise such as a squeaking sound when stepping on the panel. The panel causes the resonance, thus to reduce the noise.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
