The fixing seat is provided with a plurality of recessed portions for placing a raised access floor on and fixedly connecting with them. The socket set screw is connected by screwing into the through hole of the fixing seat; thereby the heights after screw connecting of the fixing seat and the supporting seat can be fixed. The structure is applicable to use for a network-line or pipeline laying out for raised access floors in a house, a building and a school etc.
Description
- 1. Field of the invention
- The present invention relates to a pedestal structure for raised access floors, and more particularly to a pedestal structure non-sticking to the ground and able to adjust its height immediately before or after assembling, the structure can largely reduce working hours in construction, and increase flexibility of changing wires, changing arrangement and moving of the raised access floors, it is applicable to use for a network-line or pipeline laying out for raised access floors in a house, a building, a school or an short-term exhibition field etc.
- 2. Description of the Prior Art
- For those working places widely using computers, distribution and laying-out of networks and other kind of lines are very important and necessary. Because each computer can only be connected or electrically connected with other computers through a network, intertwining of lines becomes more and more complicated when amount of equipment gets larger and larger. If in an office lines are exposed outside, they not only look ugly, but also affect walking of workers.
- A floor for networks because of being able to be elevated for assembling, it leaves at its bottom a space for threading and distribution of lines. Thereby for informationalization of a modern office, it has been a main trend to flexibly decide the amount of floors laid out in pursuance of the size of the space in an office.
- At present, there are many kinds of raised access floor products for networks in the market. Referring to
FIG. 1A showing schematically conventional raised access floors for networks being raised by pedestals A10, wherein AB adhesive or super glue A2 generally is used to stick the bottoms A12 of supporting seats A11 of the pedestals A10 onto the ground one by one. Then fixing seats A20 are connected by screwing onto the supporting seats A11, and the fixing seats A20 are adjusted for the distance of them from the bottoms A12 to decide the heights of the pedestals A10. Lastly, the raised access floors straddle for connection over recessed portions A21 of the fixing seats A20. The above stated structure can get the suitable heights of the pedestals A10 by adjustment by rotating the fixing seats A20 to adapt to heights of the ground; however, it still has the following disadvantages: -
- 1. The bottoms A12 of the pedestals A10 have to be stuck to the ground one by one by using the AB adhesive or super glue A2 for the convenience of locking by constructors. However, detachment of the pedestals A10 afterwards may still leave traces of glue when in moving to another working field, changing assembling or being necessary to change the electric lines in the floors, the surfaces of the floors have been damaged and are hard to be recovered. This really is a problem for the business of field rent-service or for offices users nowadays. And more, the bottoms A12 of the pedestals A10 after detachment will have residual traces of glue to make the pedestals A10 no more being usable, thus wastes of resources as well as cost can be induced.
- 2. When the fixing seats A20 are connected by screwing onto the supporting seats A11, a problem of the orientations of the fixing seats A20 must be under consideration. In other words, to make all the corners of the raised access floors to be placed in the recessed portions A21 of the fixing seats A20, the diagonal projection direction of each fixing seat A20 must be same as those of the other fixing seats A20. But by the fact that the ground is often uneven, if it is desired that the diagonal projection directions of all the pedestals A10 are same, it is unable to make the heights of all the pedestals A10 same, thereby the heights of all the pedestals A10 are slightly different. Thus the floors after laying out is not be truly horizontal but look uneven.
- 3. Before assembling, each pedestal A10 shall be adjusted to be horizontal, locked, and then floors A30 are placed on one by one. After assembling, if a pedestal A10 is to be once more adjusted in height, the
floors 30 around the pedestal A10 must be removed to rotate and adjust the corresponding fixing seat A20 up and down to get the desired level, and after adjustment, the pedestal A10 removed are again placed back. The process of work induces over working time, and inconvenience of working.
- Further, referring to
FIG. 1B , a U.S. Pat. No. 5,333,423 discloses an adjusting structure for raised access floors; wherein an adjuster B12 is locked with its bottom on a supporting seat B14, and has a top for slipping thereover of a sleeve B20. Thereby, when a floor B10 is placed on the sleeve B20, an adjustment tool can be used to adjust the vertical distance between the adjuster B12 and the supporting seat B14, lastly, a square cover B24 covers and seals, thereafter a screw B23 is screwed in for locking. - However, although the technique is designed to get the object of adjusting the level of the floor B10, when in assembling and using practically, by the fact that the adjustment can only be performed after detachment of the screw B23 and removing the square cover B24, the supporting seat B14 likewise needs to be fixed on the ground in favor of rotating and adjustment, this is inconvenient and still has room for improvement as to the whole designing and using.
- In view of these, the inventor of the present invention developed a pedestal structure for raised access floors based on his professional experience of years on raised access floors to solve the above stated problems.
- A primary objective of the present invention is to provide a pedestal structure for raised access floors, the pedestal structure needs not to be stuck on the ground and thereby will not damage the existing ground structure, and can be recovered for reusing.
- Another objective of the present invention is to provide a pedestal structure for raised access floors. After assembling, the heights of pedestals can be directly adjusted on the floors without lifting the floors, this can largely increase the accuracy of leveling of the floors.
- To achieve the above stated objectives, the pedestal structure for raised access floors of the present invention comprises: a supporting seat, a fixing seat and a socket set screw. Wherein the supporting seat has on the top thereof a screw bolt which is connected on its bottom with a bottom seat; The bottom seat has a protruding portion having centrally a pivot hole, the bottom of the screw bolt is in a shape of “H” for the purpose of connecting into the pivot hole. While the fixing seat has a through hole for connecting by screwing with the screw bolt to raise the fixing seat; the screw bolt has on the top thereof a hexagonal adjusting hole for engaging therein a hexagonal wrench to adjust the height of the fixing seat relative to the supporting seat. The fixing seat is provided with a plurality of recessed portions for placing a raised access floor on and fixedly connecting with them. The socket set screw is connected by screwing into the through hole of the fixing seat; thereby the heights after screw connecting of the fixing seat and the supporting seat can be fixed.
- The present invention will be apparent in its content and function after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

FIG. 7A is a schematic perspective view of the embodiment of a pedestal of the present invention, showing the four corners of the pedestal are placed respectively with floors; -
FIG. 8 is a schematic perspective view showing assembling of the embodiment of the present invention with raised access floors. - Referring firstly to
FIGS. 2-3B showing perspective views and schematic sectional views of a preferred embodiment of apedestal 10 of the present invention, thepedestal 10 comprises: a supportingseat 20, a fixingseat 30 and asocket set screw 40. - Wherein the supporting
seat 20 has on the top thereof ascrew bolt 21 which is connected on its bottom with abottom seat 22; the supportingseat 20 basically is metallic and has sufficient strength. Thescrew bolt 21 has on the top thereof ahexagonal adjusting hole 23; the bottom of thescrew bolt 21 is in a shape of “H”. Thebottom seat 22 has a protrudingportion 27 with apivot hole 271 to have the bottom of thescrew bolt 21 can be pivotally connected with thepivot hole 271. Thepivot hole 271 has a slightly larger diameter, in order thatsmall gaps screw bolt 21 and thepivot hole 27. Thebottom seat 22 has thereon a plurality ofopenings 24, further has on its bottom apad 25 that is made of plastic or rubber having thereon a plurality ofprotrusions 26. Theprotrusions 26 are in shapes for reverse hooking after smoothly slipping in theopenings 24, thus thepad 25 can be firmly attached to the bottom of thebottom seat 22. The setting ofpad 25 not only can make soft contact of thebottom seat 22 with the ground, but also the chance of oxidation of the supportingseat 20 due to the humidity of the ground can be reduced. - The fixing
seat 30 generally is rectangular, it is provided centrally with a threaded throughhole 31 to connect by screwing with the above statedscrew bolt 21. A plurality of recessedportions 32 are provided at four corners of the fixingseat 30 having thereon screw holes 33. When a raisedaccess floor 70 is placed on thepedestal 10, such as are shown inFIGS. 3A and 3B , acorner 71 of the raisedaccess floor 70 straddles atop surface 35 of thepedestal 10, while abottom surface 72 of the raisedaccess floor 70 is abutted against and held by the recessedportions 32, then screws 73 are extended through the raisedaccess floor 70 and the screw holes 33, so that the raisedaccess floor 70 can be firmly fixed on recessedportions 32. - As shown in
FIG. 4 , the interiorly threaded throughhole 31 of the above stated fixingseat 30 is longer and is protruded downwards over a bottom 34 of the fixingseat 30, this can increase the length of adjusting of thescrew bolt 21 of the supportingseat 20 in the throughhole 31 of the fixingseat 30. - The
socket set screw 40 is provided on the top of thescrew bolt 21 to be connected by screwing into the throughhole 31 of the fixingseat 30. Thesocket set screw 40 has thereon a top-to-bottom extendinghexagonal hole 41 of which the diameter is larger than that of the adjustinghole 23. The external contact circle of thehexagonal adjusting hole 23 is precisely smaller than the internal tangent circle of thehexagonal hole 41 of the socket set screw 40 (as shown inFIG. 5 ), in order to allow ahexagonal wrench 50 matching with the adjustinghole 23 to extend smoothly through thehexagonal hole 41 of thesocket set screw 40 and engage in thehexagonal adjusting hole 23 for adjusting the distance between thebottom seat 22 of the supportingseat 20 and the fixing seat 30 (as shown inFIG. 6 ). Then ahexagonal wrench 60 matching with thehexagonal hole 41 of thesocket set screw 40 adjusts downwardly the socket set screw 40 (as shown inFIG. 7 ) to tightly abut against the top surface of thescrew bolt 21 to make thescrew bolt 21 unable to rotate in the interiorly threaded throughhole 31, thus the supportingseat 20 and the fixingseat 30 are firmly connected with each other. - When the present invention is connected with raised access floors, the steps are: (1) a first raised
access floor 70 is put and raised on the ground by using fourpedestals 10, and screws 73 are used to firmly fix in the screw holes 33 of the recessedportions 32 on the pedestals 10 (such as are stated above and shown in FIGS. 3A and 3B); (2) if the ground is uneven, smallerhexagonal wrenches 50 are used to extend into the throughholes 31 of the fixingseats 30 on thepedestals 10, and are engaged in hexagonal adjusting holes 23 on the tops ofscrew bolts 21, thus supportingseats 20 are micro-adjusted in height (as shown inFIG. 6 ), at this time, thescrew bolts 21 of the supportingseats 20 are rotated to adjust the heights of the supportingseats 20, while the fixingseats 30 are stay non-rotated relative to the supportingseats 20; (3) the above steps (1) and (2) are repeated to complete a large scale engineering of raising the raised access floors; as shown inFIG. 7A , the four corners of apedestal 10 are respectively straddled by fourcorners 71 each belongs to one of four raisedaccess floors 70; (4) after assembling of these raised access floors 70 (line outlets 74 of the raisedaccess floors 70 can be alternatively arranged in a cross way or a mutual opposite way in pursuance of requirement, and their heights are corrected with laser level-correction); then largerhexagonal wrenches 60 are used (or electric drivers are used in a fast mode all around) to connect by screwingsocket set screws 40 into each throughhole 31 of the fixing seats 30 (as shown inFIG. 7 ), thereby thesocket set screws 40 are tightly abutted against the tops of thescrew bolts 21, so that thescrew bolts 21 are unable to rotate in the interiorly threaded throughholes 31; (5) lastly, according to practical requirement, a carpet ormattress 80 can be placed on the raised access floors 70 (as shown inFIG. 8 for an example,line outlets 74 of the raisedaccess floors 70 are arranged in a mutual opposite way). - Moreover, protruding
portions 27 are used to slightly raise thescrew bolts 21 in order to leavegaps 274 between each bottom surface of thescrew bolts 21 and eachpad 25, thegaps 274 can be used for absorbing unevenness of the ground. - If sometime afterwards a
pedestal 10 is to be adjusted in height, it needs only to lift theabovementioned carpet 80, and to rotate to loosen a corresponding socket setscrew 40 to be separated from the top surface of acorresponding screw bolt 21, and then ahexagonal wrench 50 is used to extend into a corresponding hexagonal adjustinghole 23 to adjust thescrew bolt 21, at this time, the corresponding supportingseat 20 will entirely be rotated following the adjusting of thehexagonal adjusting hole 23, and the function of raising or lowering thepedestal 10 can be achieved. This can save the trouble of removing the raisedaccess floors 70 around a corresponding fixingseat 30 as is the cases of conventional techniques. - According to the above stated, the present invention has the following advantages:
-
- 1. When the pedestals of the present invention are in construction, their bottoms no more need to be stuck to the ground by using adhesive for fixing on the ground, hence the ground will not be damaged. This is very convenient for fast construction, moving and changing arrangement for short-term exhibition or the business of field rent-service.
- 2. When the pedestals are not in use, they can be collected hundred percent for reuse. This not only is environment friendly, but also can promote marketing of rent service of raised access floors and pedestals.
- 3. The diameters of the pivot holes of the present invention are slightly larger in order that gaps are formed between the “H” shaped bottoms of the screw bolts and the pivot holes. Thereby if sometime afterwards a pedestal is to be adjusted in height, by providing the gap correspondingly between the bottom of the screw bolt and the pivot hole of the pedestal, when a hexagonal wrench is used to extend into a corresponding hexagonal adjusting hole to adjust the screw bolt, only the screw bolt rotates and the corresponding bottom seat is not moved. The screw bolt is easier for adjusting to achieve the function of raising or lowering the pedestal.
- 4. The pedestal structure for raised access floors of the present invention has a bottom seat on the bottom of the supporting seat, the bottom seat is added on its bottom with a plastic pad. This not only make the bottom seat to avoid oxidation to generate rust because of wet floor, but also make the bottom seat to avoid direct contact and rubbing the ground to scrape the ground.
- 5. When in assembling, a floor can be placed on after adjustment of pedestals, and after level correction, the pedestals and the ground can be locked together, such construction work is very convenient; while after assembling, if it is desired to further adjust the heights of the pedestals, it needs not to lift the floors, but needs only to use a hexagonal wrench above the floors to extend deeply into the adjusting holes to adjust the heights of the pedestals. This can reduce working time and steps.
- 6. The designing of the present invention makes four corners of the fixing seat of a pedestal to be locked onto the ground, so that in adjusting the pedestal, a supporting seat rather than the fixing seat rotates; this can avoid the situation of rotating the fixing seat on one hand, and thinking of the orientation the fixing seat to afford placing thereon a floor on the other hand; thereby, the present invention can get a high accuracy of the entire level after placing the floor.
- The embodiment given is only for illustrating 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 without departing from the spirit of this invention shall also fall within the scope of the appended claims.
- In conclusion, the present invention can get the expected objects thereof to provide a pedestal structure for raised access floors, it is extremely practicable. Having thus described my invention, what I claim as new and desire to be secured by Letters Patent of the United States is:
