Definitions

  • This invention relates to a raised false floor set up in computer and control rooms, and particularly to a combined floor pedestal and floor out assembly for supporting floor rails which in turn hold floor panels.
  • U.S. Patent No. 4,438,610 discloses a pedestal assembly which includes a height-adjustable, telescopic shaft of two sections with an enlarged base and a top bearing plate with a clamping means to support and clamp floor panels.
  • a pedestal assembly is found to be disadvantageous since the telescopic shaft, which is slim and threaded, and the bearing top plate are susceptible to damage when subjected to heavy loads, especially when the base floor below is uneven. Furthermore, it is inconvenient to adjust the height of the pedestals after the panels are installed thereon.
  • U.S. Patent Number 572836 to Sorsoleil and U.S. Patent Number No. 651,511 disclose height-adjustable telescopic pipe constructions to be placed under ground surface for supplying water and gas. These constructions can be adjusted in height to be flush with the ground surface, and are designed to be used as connectors rather than as supports which must usually be adjusted in height after supported elements are mounted thereon.
  • U.S. Patent No. 3,398,933 discloses a pedestal assembly, as shown in Figure 1, in which a nut is employed to adjust the height of a threaded rod which is inserted slideably in a lower tubular support with a bottom flange.
  • the threaded rod is also provided with a top bearing plate.
  • Such a construction is also weak.
  • U.S. Patent Numbers 1,767,323, 2,996,566 and 3,794,956 disclose floor outlet devices by means of which an apparatus, such as a computor, telephone, telegrpaph instrument, light, etc., may be readily connected with electric conductors disposed under a floor.
  • Such floor outlets generally include a hollow cylindrical support body, and a plug body inserted in the support body in a telescopic manner and having an electric outlet means mounted thereon.
  • An object of the invention is to provide a combined floor pedestal and floor outlet which has a strong pedestal and a strong bearing face for supporting floor rail and by which additional requirements for installing floor outlets can be eliminated.
  • Another object of the invention is to provide a combined floor pedestal and floor outlet assembly which is convenient for height adjustment even after floor rails are mounted on the assembly, and which has a height adjustment member capable of changing the height of the pedestal upon slight turning of the adjustment member.
  • the invention provides a combined floor pedestal and floor outlet which includes upper and lower threaded cylindrical members of enlarged cross-section interconnected by a threaded adjustment sleeve member which is sleeved around the upper and lower cylindrical members.
  • the upper cylindrical member is provided with at its top annular portion radial grooves spaced apart from each other and opening at the periphery and the top face for receiving floor rails and upstanding projections to engage with floor rails.
  • the screw threads on the adjustment sleeve member are arranged such that they can cause the screw threads of the upper and lower cylindrical members to advance simultaneously into the sleeve member.
  • the upper and lower cylindrical member can move inwardly or outwardly simultaneously relative to the adjustment sleeve member, changing appreciably the totel height of the pedestal.
  • a plug body On the upper cylindrical member is mounted a plug body in a telescopic manner.
  • the plug body includes first electric socket means which are connected with second electric socket means disposed in the upper cylindrical member, thereby enabling the wires below the floor to be connected easily to the electric elements on the floor.
  • the pedestal assembly is particularly so arranged that the height adjustment of assembly can be effected independently of the parts incorporating floor outlet means so that the adjustment therefor does not change the position of the floor outlet means or affect the arrangement of the wiring system below the false floor.
  • a pedestal assembly which includes a base drum member 1, an adjustment sleeve member 4, a support drum member 2 and a cylindrical plug body 3.
  • the base member 1 has a radially extending bottom flange 11 having four upwardly arched portions 13 each defining a passage 131. Nut 134 and screw 133 are attached to each arched portion 13 to be used for grounding.
  • At the upper portion of the base member is an external right-­hand screw thread 121.
  • the adjustment sleeve member 4 has a cylindrical wall with an upper left-hand internal screw thread 42 and a lower right-hand internal screw thread 43.
  • the lower right-hand internal screw thread 43 is engaged with the external screw thread 121 of the base member.
  • the support member 2 which has a lower external left-hand screw thread 21 engaging with the internal left-hand screw thread 42 of the adjustment sleeve member 4.
  • openings 22 at intervals to be used for attachment of electric socket members 51.
  • the socket members 51 are fitted in the openings 22 respectively by means of screws.
  • At the upper portion of the support member 2 is an annular top bearing face 23 and an internal screw thread 24.
  • the top bearing face 23 is provided with four pairs of radial grooves 25 spaced apart from each other, extending radially and opening at the periphery and at the top annular face of the support member 2 for receiving four rails 70. Between each pair of radial grooves 25 is a recessed face 26 on which is disposed an upstanding projection 27 for engaging with holes 71 of the floor rails 70.
  • the cylindrical plug 3 is fitted in the hole 20 of the drum support, and provided with an external screw thread 31 to engage with the internal screw thread 24.
  • electric sockets 34 and 35 which are connected electrically in a conventional manner with electric sockets 51 of the support 2 by means of conductors 52 as shown in Figure 3.
  • a hole 38 is provided on the plug body, through which a grounding wire (not shown) can extend from above the floor to the bottom flange 11 of the base drum 1.
  • a circular cover plate 32 On the plug body 3 is a circular cover plate 32 having a bottom attachment protrusion 321 used to penetrate into a hole 33 of the plug body 3 so as to cover the electric sockets 34 and 35 when no electric connection is desired.
  • a pull ring 322 is attached to the cover plate 32 for ease of uncovering the plug body 3.
  • the assembly according to the invention has an advantage in that the height of the assembly can be adjusted after the floor rails 70 are mounted on the support 2.
  • the adjustment can be effected by turning the adjustment sleeve member 4.
  • the adjustment sleeve member 4 can make both screw threads 21 and 121 move into or move outward simultaneously when it is turned so that the height of the assembly can be changed appreciably with a slight turn of the adjustment sleeve.
  • the material used for making the two assemblies is aluminum ( Al-6061, T6) which has a young's modulus of 6.83 x 106N per sq.cm, an ultimate strength of 3.1 x 104N per sq.cm, and a yield strength of 2.75 x 104 N per sq.cm. The yield strength which is lower than the ultimate strength is used for determining the failure of the assemblies.
  • the dimensions and the moments of inertia (I) of the two assemblies are as follows: Assembly 1 conventional Assembly 2 present invention Outside diameter (cm): 2.87 8.14 Inside diameter (cm): 2.57 7.84 Cross sectional area (cm2): 1.282 3.765 Moment of inertia (cm4): 1.185 30.046
  • Tests were made, using four floor tiles placed side by side adjacent to each other and assemblies 1 or 2 supporting the floor tiles at their corners.
  • a central one of assemblies 1 or 2 is a common support which supported the corners of all four floor tiles.
  • a load of 1500 kgf per sq.in was applied on one of the floor tiles at two locations, one location being at one side of the floor tile ( Figure 4) and the other at the center of the floor tile ( Figures 5).
  • the load acting on the central assembly for the case of Figure 4 and 5 were determined by computer analysis. The results of the determination showed that the load acting on the central assembly was 28,756 N for the case of Figure 4 and 14,700N for the case of Figure 5.
  • Figure 6 illustrates schematically the central assembly 1 or 2 which is placed on an inclined floor. Tables 1 and 2 show the results of the determination. The assembly 1 or 2 is considered as being in failure when the ⁇ max is greater than ⁇ y where ⁇ y is the yield strength of the material as described hereinbefore.
