Definitions

  • the present invention relates to a stanchion or post, and more particularly, but not exclusively, to a stanchion or a supporting post suitable for supporting a handrail of scaffolding for supporting workers and working machines in building construction sites, ship building and repair, civil engineering work, etc.
  • Patent specification US-A-3938619 describes a stanchion for clamping to a support structure of the type comprising: an elongate member; a tubular member slidably mounted on the elongate member; means for releasably fixing the tubular member to the elongate member in any selected one of a plurality of positions; a pair of parallel opposed clamping jaws mounted on the elongate member and tubular member, respectively, one of the jaws comprising a screw-threaded socket into which an adjustable screw-threaded jaw-piece is fitted, such that, with the fixing means holding the tubular member at a desired position on the elongate member, the jaws can be clamped onto the support structure with one of the members extending upwardly from the structure; and a fitting mounted on the upwardly extending member for supporting a rope or handrail.
  • the stanchion of US-A-3938619 has support members of circular cross-section, and the fixing means comprises a pin which is passed through selectably aligned holes in the support member.
  • the fixing means comprises a pin which is passed through selectably aligned holes in the support member.
  • a stanchion for clamping to a support plate or board comprising: an elongate member; a tubular member slidably mounted on the elongate member; means for releasably fixing the tubular member to the elongate member in any selected one of a plurality of positions; clamping means including a pair of parallel opposed clamping jaws mounted on the elongate member and tubular member, respectively, a first one of the jaws comprising a screw-threaded socket into which an adjustable screw-threaded bolt having a first jaw-piece is fitted, and the other jaw being disposed parallel with and spaced from the first jaw, such that, with the fixing means holding the tubular member at the desired position on the elongate member, the jaws can be clamped onto the support structure with one of the members extending upwardly from the structure, the bolt being rotatable to move the first jaw towards and away from the other jaw; and a fitting mounted on the tubular member for supporting a rope or hand
  • Figures 1 and 2 show a known device, in which the stanchion or post comprises a tubular body 2 which is vertically slidably inserted in an outer tubular body 1.
  • the outer body 1 is provided with a plurality of holes 3 located at equally spaced vertical locations along its height.
  • the inner tubular body 2 is also provided with holes 4 in correspondence with the holes 3 provided in the outer tubular body 1 and at equal spacing.
  • a laterally extending bracket 5 is fixed to the lower end of the inner tubular body 2, and a dish 7 is provided on a bracket 5.
  • the dish 7 contains an elastomeric material 6, such as hard rubber, and the dish 7 and the elastomeric material 6 form the lower part A of a clamping means.
  • the clamping means includes a freely expansible upper part B which is fixed to the outer tube 1 by a bracket 8 and which extends downwardly.
  • the clamping means constituted by the lower part A and upper part B serves to clamp against the scaffolding plate or board 9 from both sides of the plate or board.
  • the upper part B of the clamping means comprises a cylindrical body 10 and a nut 11 fixed within the cylindrical body 10.
  • a bolt 12 is engaged with the cylindrical body 10 through the nut 11 and may be threadably adjusted therein vertically.
  • a dish 15 which is fixed by the head portion 13 of the bolt 12 and a nut 14.
  • An elastomeric material 16, such as hard rubber, is contained in the dish 15.
  • a pin 18 is connected to the bracket 8 through a chain 17 and can be inserted through aligned holes 3 and 4.
  • the stanchion is secured to the scaffolding plate or hoard 9 by the following steps: If the thickness of a scaffolding plate or board 9 is considerably large, the inner tube 2 is slidably extended in correspondence with the thickness of the scaffolding plate or board 9 and at the location to align the hole 3 of the outer tube 1 with a hole 4 of the inner tube 2, and the pin 18 is inserted through the aligned holes 3 and 4 to fix the inner tube 2. With this arrangement, it is possible to adjust the length of the stanchion composed of the outer tube 1 and the inner tube 2.
  • the elastomeric material 6 of the lower clamping means A is applied to the lower surface of the scaffolding plate or board 9, and the upper clamping means B is located above the upper surface of the scaffolding plate or board 9.
  • the elastic material 16 is applied to the plate or board 9 by rotating the head 13 of the bolt 12 and lower it.
  • the scaffolding plate or board 9 is tightly clamped by means of the upper and lower parts A and B of the clamping means to fix the outer and inner tubes 1 and 2 tightly to the scaffolding plate or board 9. If the thickness of a scaffolding plate or board 9 is considerably small, it is possible to mount the stanchion to the scaffolding plate or board 9 simply only by sliding the inner tube 2 upwardly and by adjusting the upper part B of the clamping means.
  • FIGS 3 to 7 show a stanchion according to an embodiment of the invention which is similar in construction to some extent, to the stanchion of Figure 1. Therefore, like reference numerals designate similar parts, and their detail description is omitted.
  • an inner tubular body 2 a is slidably inserted through an outer tubular body 1 a .
  • the outer tubular body 1 a is in the shape of a cylinder with its lower end 1 b of a small diameter, while the inside tubular body 2 a is in the shape of a hollow rectangular shape, as shown in Figure 4.
  • the inside tubular body 2 a has in its upper end a pair of diametrically opposed cut-outs a , forming a pair of tongues 2 b , each extending obliquely outwardly from a peripheral edge of the respective cut-out a and serving as a stop.
  • the inside tubular body 2 a may be formed by shaping a cylindrical tube into a rectangular hexahedron, or a tube in the shape of a rectangular hexahedron may be used for the inside tubular body 2 a .
  • the rectangular hexahedron causes an increased degree of strength and serves to prevent the inside tubular body 2 a from being displaced in circumferential directions.
  • the inside tubular body 2 a is inserted into the outer tubular body 1 a from the upper end thereof and; as the upper end of the inside tubular body 2 a arrives at the lower end of the outer tubular body 1 a , the two tongues 2 b are brought into engagement with the small-diameter portion, thus preventing the inside tubular body 2 a from being removed from the outer tubular body 1 a .
  • One or more mounting members 32 are mounted on a peripheral surface of the outer tubular body 1 a , through which members a handrail such as a rope or tube may be threaded.
  • a hook bolt d is inserted horizontally through the upper portion of the outer tubular body 1 a and is secured at one end by a nut e .
  • the hook bolt d is adapted to receive or support a handrail in the form of a tube.
  • a dish 7 a mounted on the bracket 5 has a central hole, through which a downwardly tapered locking portion 6 b of the elastomeric material 6 a is to be forcibly inserted at that time the diameter of the locking portion 6 b becomes smaller and, upon insertion, then recovers under its own elasticity, thus preventing the elastomeric material 6 a from being removed from the dish 7 a .
  • a dish 15 disposed at the upper part B has an inside taper surface, in which an upwardly outwardly diverging taper surface f (Figure of the elastomeric material 16 a is to be fitted so as to prevent the elastomeric material 16 a from being removed from the dish 15.
  • the outer tubular body 1 a has in its lower portion a pair of holes 3a, while the inside tubular body 2 a has a plurality of holes 4 a spaced at equal distance twice the distance between the two holes 3 a in the outer tubular body 1 a .
  • the inside tubular body 2 a can be varied in the range of vertical adjustment. For instance, if the distance between the adjacent holes 3 a is 60 mm and the distance between the holes 4 a is 120 mm, the inside tubular body 2 a can be longitudinally adjusted within a range from 60 mm to 180 mm.
