Definitions

  • the object of this invention is to provide a jack or a prop unit primarily for supporting raised or modular flooring but capable of use for a wide variety of other support or similar purposes and which is also capable of simple, strong and durable construction with provision for axial or height adjustment. Practical advantages in these and other respects will be apparent from the following disclosure.
  • a support jack comprises at least a base member and a head member having an interfitting location in relation to one another for relative turning movement about a generally common axis, said members having co-operating end faces having an abutting helical co-action whereby on relative turning of the members they are axially adjusted for axial extension or retraction relative to one another, the end faces further having a non-slip engagement for maintaining the members in a relative axial extent to which they may be adjusted. «
  • the jack basically comprises a base member 1 and a head member 2 arranged to locate in relation to one another for relative turning movement about the vertical axis of the jack.
  • the base 1 is shown provided with an upstanding central and axial projection 11 which engages a corresponding bore 21 in the head 2 or vice versa and with preferably further or alternative interfitting location as referred to below.
  • the base 1 and head 2 have co-operating helically formed end faces 10,20 respectively which in the assembled condition of the jack, abut one another for cam-like abutting co-action so that on relative turning of the head 2 and base 1, the head 2 is caused to rise axially relative to the base 1 or retract according to the direction of relative rotation.
  • Minimum and maximum height settings are indicated in FIGURES 5 and 6.
  • three equi-spaced helical end faces 10 provided in a successive manner on the base 1 and of the same height and angular extent co-operate with three corresponding helical end faces 20 on the head 2 in a multi- start arrangement for providing firm and balanced support of the head 2.
  • the number of such faces 10,20 may be varied according to requirements.
  • the co-operation of the end faces 10,20 is such that the head 2 and base 1 are capable of remaining adjusted when under considerable load and for this purpose and as shown in the drawings the end faces 10,20 are radially serrated to provide teeth 12,22 for positive non-slip engagement which not only ensures that the head 2 and base 1 remain relatively adjusted without axial displacement (e.g. due to vibration) but also facilitates their adjustment by the step location or indexing afforded by the teeth 12,22.
  • the teeth 12,22 are shown of ratchet or buttress form in a direction to resist downward movement of the head 2 relative to the base 1 and which also further facilitate upward adjustment of the jack by the teeth 22 of the head 2 riding over those 12 of the base 1.
  • the faces 10,20 should be coated with adhesive so as to bond together after adjustment.
  • the end faces 10,20 are situated adjacent the outer periphery of the cylindrical base 1 and the head 2 and, particularly where toothed, only extend radially inwards for a sufficient extent for adequate bearing surface area so as to enable suitably spaced radial teeth 12,22 to be employed without undue convergence.
  • the end faces 22 are shown arranged about a co-axial spigot 24 which locates within a recessed upper end or socket 14 of the base 1 bounded by the helical face formations 12 or ramps of the latter in order to provide further (or alternative) co-axial location of the head 2 on the base 1 for their relative turning movement.
  • the lower part 100 of the base 1 is shown extending in a radially outward direction to provide suitable base area for contact with the ground or similar supporting surface such as a sub-floor.
  • the head 2 and base 1 may be produced as castings such as die-castings or mouldings in any suitable material such as metal, e.g. aluminium or plastic of appropriate strength and especially in glass re-inforced cement (GRC) for high strength and durability as well as low cost manufacture.
  • GRC glass re-inforced cement
  • the cement may have a glass fible content of the order of 4% and owing to their form the head 2 and base 1 amy be cast in such material in suitable moulds which may be of plastic material such as polythene, e.g. for disposable use.
  • Clay or glass re-inforced plastic material may be also used as well as glass fibre re-inforced gypsum.
  • the head 2 For supporting panels of a raised or modular floor at adjacent corners of the panels, the head 2 receives a suitably formed locating member or head plate 3 shown provided with upstanding radial ribs 30 for location between adjacent floor panels 5 (FIGURE 7) in the usual lower clearance between the sides of the latter.
  • the head plate 3 may be located or inserted at 32 in a recess 23 in the top of the head 2 or may otherwise locate thereon such as by cap fitting.
  • the head plate 3 may be adhesively mounted on the head 2 or may be moulded in the head during manufacture of the latter.
  • the plate 3 may include recesses 31 or openings for receiving corresponding projections from the underside of the panels such as from corner plates thereon, (i.e. as per British patent No. 1,536,424), e.g. in the multi-purpose arrangement shown in FIGURE 4.
  • the head plate 3 may be otherwise formed for engaging or locating panels, and/or for other suppord suppoung.
  • the head plate 3 is also shown provided with an annular seating groove 34 to enable a tubular upright extension member 4 to be supported from the jack, which tube or column 4 may then receive a head member or plate 6 (FIGURES 8 and 10) at its upper end for locating engagement with floor panels.
  • a head member or plate 6 (FIGURES 8 and 10) at its upper end for locating engagement with floor panels.
  • the lower end of the tube 4 would be adhesively secured in the annular groove 34 and the head 6also secured by adhesive on the tube 4.
  • the plate 3 or 6 may have perforated lugs as shown at 37 in FIGURE 4 for the attachment of stringer members 7 (FIGURES 9 and 10) in supporting panels 5 or other floor members.
  • the upper end of the head 2 may be integrally formed e.g. in a similar manner to the plate 3 for direct locating engagement with or between the floor nanels 5 and/or for other support purposes.
  • Stop means is also preferably provided for limiting relative turning movement of the head 2 and base 1 so as to prevent the rear or trailing ends of the head faces 20 being adjusted beyond the upper ends of the base faces 10.
  • Such stop means is shown consisting of an inward radial projection 25 of the head 2 (FIGURE 3) which engages an angular recess 15 about the central projection 11 in the base 1 or vice versa.
  • Other suitable stop means may be emnloyed.
