Definitions

  • the present invention relates to an articulated joint for mobile walls, which forms a variable angle, in particular suitable to angle variations in the range between about 90° and 270°.
  • mobile walls which are desi­gned to subdivide wide areas and define rooms of more limited size, comprise panels joined together by means of articulated joints or stanchion joints.
  • the angles formed at each joint by two adiacent panels are fixed (more frequently 180° for aligned walls or 90° for walls at right angles to each other) and angle varia­tions are not allowed. Therefore if the problem arises of disassembling and re-assembling the walls, so as to form different angles therebetween, it will be necessary to replace the joint itself, and possibly modify the couplings with the panels forming the walls.
  • Another problem of these mobile walls is the continui­ty of the operative performances provided by them such as the possibility of being fitted with various facilities, the wiring passages, the acoustic insula­tion, the fire resistance, etc.
  • Another object of the present invention is that of providing a joint for mobile walls having the possibility of being fitted with various installations, which can ensure the continuity therethrough of the operative performances provided by the joined walls.
  • a joint comprising a pair of metal members to be fitted respec­tively as head and bottom at the upper and lower end of a tube adapted to form the core of said joint, each of said members showing, at the portion remaining outside of the tube, a first circular groove at some distance from its periphery and co-axial with the member itself, being formed at the outer surface of the head or bottom member, as well as a second annular groove formed circumferentially at the periphery of said head or bottom member at a small distance from said outer surface, there being provided first and second engaging means, respectively in an axial and a transverse direction to the tube, with said first and second groove, each of said engagement means being able to be fastened to the other and to a U-shaped metal bracket which in turn can be secured by known means to the end upright of a mobile wall.
  • an inner metal tube passes across at least part of the tube through holes provided in said head or bottom members, with adjustable studs at the outside of said tube for adaption to the floor and to the ceiling, said adjustable elements being provided with fairleads and possibly surrounded by removable, non-structural covering portions, respectively at the bottom and top side of the tube.
  • an articulated joint 1 is shown, which is suitable to connect at least two mobile walls 2,2′ (Fig.2) at an angle ⁇ in a range of values between at least 90° and 2700, with the maximum limits of 85-275°.
  • the range is of 87-273°.
  • the assembly can be easily disassembled and re-assem­bled, such as with a different angle ⁇ , still within the above-mentioned range of values.
  • Joint 1 comprises a steel tube 10 forming the joint core, at the ends of which two lighter metal members are fitted, e.g. of aluminum, preferably sha­ped as shown with reference numerals 20 in the drawings, i.e. with a portion having reinforcing radial fins 21 as a guide about a central tubular part or cylindrical sleeve 22 for fitting into the tube 10, and a portion 23 whose diameter is greater than the inner diameter of tube 20, substantially of the same size of the outer one, thus providing a head or bottom member at either ends of the tube itself.
  • a metal inner tube 11 passes throughout the hole in the cylindrical sleeve 22 and, fastened in a known manner at the end of the latter, may be adjusted by screw, such as like a tur­nbuckle, according to the distance between the tube end, or better the outer surface 24 of head or bottom member 20, and respectively ceiling and floor.
  • Fig. 4 shows the upper head member 20 and the associate inner tube 11 (which could possibly pass throughout the whole length of tube 10) of adjustment with respect to the ceiling, with thrust bearing spring 13 and adjusting screw nut 14.
  • the mem­ber portion 23 designed to be kept at the outside of tube 10 has on its outer surface 24 a circunferential groove 25 at some distance from its periphery, which extends parallel to the joint axis, as well as a second annular groove 26, on the periphery of portion 23, being in a radial direction.
  • a L-shaped bracket member 31 has the longer leg 31a of said L directed longitu­dinally, to the opposite side with respect to the direction of sleeve 22, and fits at the inside of said groove 25 with a tooth 35 formed on the shorter leg 31b of L shape.
  • a block 32, to be fixed to bracket 31 by means of screws 37, has in turn a radial tooth 36 for fitting into the annular groove 26.
  • Both teeth 35, 36 extend along a substantial arc length, thus increasing the surface of contact with the associate groove.
  • Member 31 and block 32 associated thereto form therefore two hooks being able to slide in the respective grooves 25,26 until the tightening of screws 37 not only locks the two members to each other, but gives rise to a moment at fixed end due to the action of two mutually perpendicular forces, whereby their fastening to head or bottom member 20 is complete.
  • the assembly of members 31 and 32, and hence of the associate end member 20 (head or bottom) is in turn caused to be fixed to the end upright 12 of wall 2 in any known way.
  • the upright 12 which is also adjustable by screws at the ends, passes through a tubular element 42 fixable to a pair of mutually facing C-shaped sec­tions, thus forming a box-type section 43 embedded in the panel of wall 2.
  • the box section 43 is secured by means of opposed clamps 44 to both free legs of a channel sec­tion 41 which in turn is fastened to bracket 31 by screws 38.
  • the clamps 44 can be tightened onto the section 41 by means of a through screw 45.
  • the block 32 will engage section 41 not only through the bracket 31, but e.g. directly by means of a lug 33 abutting against a side of said section.
  • a fastening device for a second mobile wall 2′ At an angle from the axis of wall 2 on the head and bottom mem­bers 20 there can be similarly mounted a fastening device for a second mobile wall 2′, as shown in broken lines in Fig. 2.
  • the limits of angle are dictated by the angle formed by adju­sting members 2a, 2b for finishing wall 2 up to joint 1 and the corresponding members 2'a, 2'b of wall 2′.
  • the range thus defined is usually of not less than between limits of 90-270° and, in the embodiment shown, it reaches limits of 87-273°.
  • Fig. 1 With reference in particular to Fig. 1 the end portions of joint 1, being comprised between the lower and upper ends of tube 10, i.e. the outer surfaces 24 of bottom and head members 20, and respectively floor and ceiling, are completed with non-structural cover elements 16, 16′ of synthetic material like ABS, re­movable for inspecting. Their function, in addition to be of aesthetical nature, is that of protecting fairlead supports 18,18′ which are provided in that zone, as they are mounted to the inner tube 11.
  • the whole assembly is further completed by an upper fi­nishing element 17, which may be again formed of a steel or ABS tube, cut at the desired length.
  • the joint is ensured, by providing e.g. parts 16, 16′ and 17 of the same diameter of tube 10, but also the continuity of facilities passing theretrough from a wall 2 to that adjoining 2′, whereby the functions provided by them are not subject to interruptions when passing from a wall to another, even in case of three or four walls branched off from the same point. Also the con­tinuity of possible (thermal and/or acoustic) insula­ting materials can be guaranteed across the joint.
