To enable the post to be conveniently mounted between the floor and ceiling of a room, the post has feet 17, 23 at either end thereof and has a coarse telescopic adjustment provided between the upper foot 17 and post 10 by means of a rod 15 projecting from the upper end of the post and adjusted by means of a pin 16 engaging in one of a number of holes spaced along the rod. A fine adjustment is provided by means of a screw jack 20, 24 between the lower end of the post 10 and the foot 23 to enable the post to the jammed between the floor and ceiling. Rod 15 engages in a bearing 18 in the upper foot and the lower foot 23 provides a bearing in which the head 21 of the jack 20 engages to permit the post to be turned when jammed in position to enable access to the tool holders on the post. <IMAGE>

Description

SPECIFICATION Improvements in or Relating to Fixture Posts This invention relates to fixture posts.

According to this invention a fixture post comprises a hollow tubular extruded member having a plurality of slots spaced around the circumference thereof and extending lengthwise of the member to receive a plurality of fixtures at any required locations around and along the member, an extension element engaged in and projecting from one end of the member, means to hold the element extended from the member at a required extension over a range of extensions and rotatable feet on the projecting ends of the extension and the other end of the member to support the post/element between upper and lower surfaces with the post extended to clamp the feet to the surface whilst enabling the post to turn about said mounting.

The invention also provides a holder for a piston grip type electric power tool comprising two side-by-side rigid walled holsters and a bracket for mounting the holsters, one of the holsters being adapted to support a body of a power tool with the piston grip of the power tool extending into the holster and the other holster being adapted to receive a coiled electric flex for the power tool.

The following is a description of some specific embodiments of the invention, reference being made to the accompanying drawings in which: Figure 1 is a diagrammatic elevation view of a fixture post according to the invention with a part of the post cut away and a section through the post shown in place of the cut away part; Figure 2 is a diagrammatic perspective view of the fixture post in use; Figure 3 is a detail perspective view of one tool carrier for the post as shown in Figure 2; Figure 4 is a detailed view of one modification to the post; and Figure 5 is a further modification.

Referring firstly to Figures 1 and 2 of the drawings there is shown a fixture post for mounting between a floor and a ceiling or beam of a room, garage, workshop or the like and comprising a long extruded tubular cross-section member 10 which comprises a basic cylindrical tube 11 having full sets of pairs of T-section flanges 12 formed integrally therewith and extending lengthwise of the tube 11. The uprights of each pair of T-section flanges lie parallel to one another and the cross-pieces lie in a common plane so that the uprights provide, between them, a space to receive the head of a bolt 1 3 the shank of which projects between the cross pieces for attachment to a tool carrier or the like to fix the tool carrier to the member 10 as described later.

The inner side of the tube 10 is formed with a number of radially inwardly extending plane flanges 14 which extend lengthwise of the tube. A rod 1 5 projects from the upper side of the tube, the lower end of the rod being supported by the inner ends of the flanges 14. The rod is provided with a number of spaced transverse holes 1 6 and a pin is provided which is engageable in any one of the holes to hold the rod 1 5 extended from the tube by a required amount. The extension of the rod 1 5 is varied by inserting the pin in the appropriate hole 1 6.The upper end of the extension rod 1 5 carries a cushioned pad 1 7 in which a downwardly open bush 18 is mounted closed at its upper end to receive the upper end of the rod 1 5 and allow the pad 1 7 to rotate with respect to the rod. The upper surface of the pad bears on the under side of the ceiling or beam indicated at 19 under which the post is to be mounted.

The bottom end of the tubular member 10 has a jacking screw 20 extending into the tubular member 10 the inner ends of the flanges 14 being formed with a screw thread with which the jacking screw 20 engages. The lower end of the screw 20 carries a knurled head 21 having a shallow conical underside 22 which bears in a seat formed in the upper surface of a nylon glide/pivot 23 which bears on the floor. The head 21 can pivot with respect to the glide 23 to allow the post to turn with respect to thQfloor as required.

The length of the posts is adjusted coarsely by inserting the pin in the appropriate hole 1 6 in the extension rod 1 5 and the jacking screw 20 is then used to further extend and clamp the rod between the floor and ceiling or beam by rototating the knurled head 21. When the post has been clamped in position, a locking collar 24 on the jacking screw 20 is screwed up against the underside of the tubular member 10 and thereby locks the jacking screw against further rotation.

Figure 2 of the drawings shows the post of Figure 1 with a number of different carriers attached to the tubular member 10 for supporting the common tools of a handyman. Adjacent the lower end of the tubular member 10 two plates 25 are fixed to either side of the post with a gap 26 between them in which the blades of screwdrivers 27 and saws 28 are engaged with the handles projecting above the slots. The plates can also carry further tools as indicated. Above the plates 26 a double holster 29 is mounted on the post for a power drill 30. The double holster is illustrated in greater detail in Figure 3 to which reference is now made.As will be seen, the double holster comprises two back-to-back holsters 31, 32 one of which provide an upwardly open socket for receiving the piston grip of a power drill with a body of the drill resting on the top of the holster and the other, 32, of which receives the coiled power flex of the drill. A single flange 33 projects from the holster for fixing to the post 10 as described previously. Above the double holster 29 there are a number of laterally extending arms 34 for carrying tools such as chisels 35, hammers 36 and screw jars 37 and a square ring 38 is also mounted on the post for carrying tools such as pliers, pincers and the like.

Figure 5 of the drawings shows a modification to the arrangement of Figure 1 in which a plurality of disc springs 40 are located on the extension rod 15 on the upper end of the tubular member 10. The pin engaged in a holster 1 6 in the extension rod bears on the upper end of the pile of disc springs as opposed to the upper end of the tubular member and the pin is inserted in a hole 1 6 in the rod such that the pile of disc springs 40 is automatically compressed as the post is erected and the compression in the spring 40 is sufficient to hold the pad 17 and glide 23 firmly clamped to the ceiling and floor, In this arrangement the jacking screw 20 may be dispensed with and the lower end of the tube 10 shaped to bear direct on the glide 23.

Instead of the disc springs 40, the spring device could comprise a coil spring or a resilient pad.

Figure 5 shows a further arrangement in which the transverse holes 1 6 and pin for the extension rod are a one way spring, comprising a washer 41 through which the rod 1 5 extends, the periphery of the washer is formed at two diametrically opposite locations with two inwardly extending arms 42 on the side adjacent the upper end of the tubular member 10. The inner ends of the arms 42 frictionally engage the extension rod 1 5 to lock the device in position on the rod and engagement of the inner ends of the arms 42 when the rod is compressed against the ceiling so as to enhance the frictional engagement of the arms with the rods. To release the arms, two legs 43 extend upwardly and outwardly from the outer ends of the arms at the periphery of the washer 41, the legs being sprung inwardly to release the inner ends of the arms from the rod 15.

The double holster described above may be used for supporting other electric power drills having pistol grips and the holster may also be mounted otherwise than on the fixture post described above. The holster may have the mounting flange on the front rather than on the rear side and may be omitted altogether in which case the holster is mounted by a fixing through the wall of the holster. The wall of the holster may also be provided with a slot such as a key-hole slot for holding a key (e.g. a chuck key) for locking a tool in the tool holder of the power tool.
