Definitions

  • the present application relates to an assembly comprising a vertical guide, one or more supporting arms movable within the vertical guide and means by which a supporting arm can be secured in the vertical guide.
  • UK-A-2 082 893 discloses a vertical guide in which a supporting arm having a dovetail guiding element fits.
  • the dovetail element has a straight elongation extending into a recess in the supporting arm and can be pulled further into the supporting arm by a set screw. By this the arm is clamped, which, however does not give an actual guaranteed clamping.
  • PCT application WO 92/09221 discloses a supporting arm in which a small flexible plastic block is mounted which can be pulled back by a screw in such a way that an expanding portion of it will contact the vertical guide. With this solution too, there is no secure clamping. In these known systems, the supporting arms are continuously adjustable, which leads to the important disadvantage, that movement after clamping is not exactly unreal.
  • the object of the invention is to provide for an assembly which does not have said disadvantages, in which the supporting arms can take up guaranteed positions and in which the assembly has been arranged in such a way, that it will suit anywhere.
  • the vertical guide comprises a base part having the spaced-apart holes therein, said base part being provided with raised edge portions and said edge portions being provided with legs facing each other.
  • the solution according to the invention provides for a separate securing member which realizes guaranteed positions of the supporting arms with the help of the holes in the base part of the vertical guide. Given the fact that the holes are situated within the vertical guide, which can be blind round holes of a relatively limited diameter, one will obtain a system in which the appearance will not be hindered by the known slots or keyhole-shaped holes of other systems.
  • the securing member comprises a body being mounted transversely to an axis of the securing member, in which the projecting stub forms an extremity of the axis, and in which the width of the body is narrower than the distance between the legs facing each other and the length of the body is larger than the distance between the raised edge portions.
  • the length, and in particular the length in diagonal direction, of the body is larger than the distance between the raised edge portions.
  • the securing member can be mounted at any desired height in a hole in the base part of the vertical guide by the stub, and by rotating the securing member a quarter turn, in which the body with the longitudinal direction is brought from a vertical position to a horizontal position. Then the body will contact the raised edge portions and will have been locked in the vertical guide.
  • the body is provided with cams situated diagonally opposite each other, which are intended for contacting the sides facing the base part, of the legs projecting towards each other, on rotation of a securing member being stuck into a hole with the stub.
  • cams which will contact the bottom of the legs facing each other cams which will contact the insides of the raised edge portion may also be provided.
  • the supporting arm contact the securing member. It is possible, for example, to have supporting arm and securing member contacting each other according to a horizontal contact surface, however, this is not preferred.
  • the body is at least partly divided in two planes sloping in opposite directions along the axis in longitudinal direction of the body.
  • a supporting arm has one extremity provided with at least one guiding element, intended to be received into a vertical guide, which extends up to both sides of the supporting arm, in which said guiding element is provided with a bevel at the side pointed downwards.
  • the supporting arm will come to bear on a slanting surface of the body of the securing member with the bevelled plane, which, definitely in case of a loaded supporting arm will provide the securing member from being rotated and also provides for a further clamping of the securing member. In this way, an additional security is obtained with these further measures. Further, the lowermost part of the guiding element is forced towards the legs of the vertical guide facing each other, as a consequence of which tilting of the supporting arm around this point is impossible and an appropriate position of the supporting arm in relation to the vertical guide is guaranteed.
  • a profile e.g. a corrugation structure
  • a profile can additionally be provided on at least one of the contact surfaces between securing member and supporting arm. Due to this, movement of a supporting arm in relation to a securing member can be completely prevented.
  • the guiding element has a recess in the middle, as a consequence of which said guiding element can fall partly around the axis of a securing member. Due to this, the maximum possible contact surface between supporting arm and securing member will be realized.
  • Fig. 1 shows a vertical guide 1 having a base part 2, raised edge portions 3, 4 and legs 5, 6 turned towards each other.
  • the base part 2 contains spaced-apart blind holes 7 intended for receiving stubs 9 of securing members 8.
  • supporting arms 10, 11 of different lengths have been mounted, their extremities projecting into the vertical guide being provided with a first and a second guiding element 12, 13.
  • the supporting arms are provided with pairs of bearing surfaces 14, 15, said bearing surfaces being provided with holes for fastening means.
  • Shelves 16, 17 have been mounted on the bearing surfaces 14, 15.
  • Figs. 3A-E show a number of views of securing member 8 substantially consisting of a pin 18 and a body 19 connecting to it, said pin 18 at one side ending in a stub 9 projecting from said body 19 and at the other side ending in an actuating member 20.
  • the body 19 is elongated in which the width of said body is smaller than the width of the opening between said legs 5, 6 turned towards each other of vertical guide 1.
  • the length of said body 19 can chosen to be smaller, equal to or larger than the distance between the raised sides of the vertical guide, in which preferably at least the length according to the diagonal is larger. In the embodiment illustrated, a smaller length according to the axis and a larger length according to the diagonal were chosen, as a result of which the body can be situated approximately square to the axis of the vertical guide.
  • the contact surface of body 19, with which it will come to bear against the base part 2 of the vertical guide 1, is completely flat, just like the base part 2.
  • two angle portions 21, 22 situated diagonally opposite one another are rounded off in such a way, that there the diagonal distance is smaller than the distance between the raised edge portions 3, 4.
  • cams 23, 24 are provided at the other corners, said cams are intended to bear against the inner sides of the legs 5, 6 turned to each other.
  • cams 23, 24 it is equally possible to design the cams in such a way that they will come to bear against the raised edge portions 4, 5.
  • the part of the top side of body 19 which is located between the cams 23, 24 is divided in two slanting surfaces 26, 27 along the axis 25 in longitudinal direction. Of said slanting surfaces 26, 27, always one surface will be the contact surface against which a guiding part 13 of a supporting arm 10, 11 will come to bear.
  • Figs. 4A-C illustrate a number of views of a supporting arm 11 in which particularly the guiding elements 12, 13 at the extremity of the supporting arm 11 are important. It would also be possible to choose an integral guiding element instead of two separate guiding elements.
  • the lowermost guiding element has parts 28, 29 of which part 28 has a width which is larger than the opening between the legs 5, 6 turned to each other and slightly smaller than the distance between raised edge portions 3, 4 of the vertical guide 1.
  • Part 29 has a width which is smaller than the distance between the cams 23, 24 of the securing member 8 and also smaller than the opening between the legs 5, 6 turned to each other.
  • part 29 has a bevel 30 at the back, which is the surface of contact with one of the surfaces 26, 27 of the securing member 8.
  • the bevel 30 and the surfaces 26, 27 can be provided with a corrugated structure as a result of which they can properly engage. This prevents supporting arm 10, 11 and securing member 8 from being easily movable in relation to one another e.g. when the supporting arm is unintendedly hit from below.
  • Fig. 1 the contact of surface 30 with one of the surfaces 27, 28 of said securing member 8 is indicated diagrammatically. Owing to this, guides 12, 13 will come to rest against the legs 5, 6 turned to each other and owing to the locking of guide 13 between securing member 8 and legs 5, 6 turned to each other, tilting of a loaded supporting arm is excluded. Furthermore, the securing member is additionally held within a chosen hole 7.
  • Fig. 4A indicates a recess 32 providing sufficient space for bringing actuating member 20 in the appropriate position.
  • Figs. 5A-B illustrates an embodiment in which the lowermost part 29 of the guiding element 33 has a bevel 30 downwards continuing in a connecting, straight part 34. There, the extremity is provided with a further bevel 36.
  • This provides a proper locking between supporting arm 11 and securing member 8 as a result of which it is not easily possible to move said support arm in upward direction in relation to said securing member in case of e.g. unintended exertion of a force onto the bottom of said supporting arm.
  • a rib 37 is provided on guiding element 33, which rib, in case of a supporting arm placed in a vertical guide 1, will come to rest between the legs 5, 6 turned towards each other and fittingly connect to them. This rib further contributes to a stable locking of a supporting arm 11 within a vertical guide 1, in which in particular lateral movement of the supporting arm is prevented.
