Definitions

  • the present invention relates to an attachment member, intended to facilitate attachment of preferably panelshaped elements against supporting sections, which sections at the plane of attachment include two towards each other directed parts, the free edge portions of which restrict a groove intermediately located between the parts.
  • attachment against this type of supporting sections has previously usually been accomplished by bolt/nut combinations, and as an example of such prior art, reference is made to the attachment means disclosed in GB, A, 399 581.
  • a major disadvantage with previously known types of attachment means is the fact that same can run freely in the existing groove of the supporting section, until the screw/nut combination has been tightened, and this disadvantage is particularly obvious for vertically extending sections.
  • a further disadvantage is, that previously known attachment means have a relatively large extension in direction from the attachment plane of the supporting section, and with regard to partition wall constructions for example, it is difficult to attach a covering flexible strip in the joint between two wall elements.
  • the object of the present invention is to disclose an attachment member, which completely removes the disadvantages related to previously used types, and which facilitates extremely rapid attachment of, for example, partition wall elements against supporting and vertically extending sections.
  • a specific advantage of the attachment member according to the present invention is, that it comprises of one single member, and that same can be massproduced by use of a press tool, and that no screw thread is required. Mounting and dismounting can be performed without use of special purpose tools, and the attachment properties for the established joint are also extremely favourable. Necessary time for mounting, or dismounting of the attachment member, can also be reduced to a minimum. Furthermore, it is extremely easy to attach a protective covering strip, since the attachment member only to a minimum by space requirements prevents such an operation.
  • the attachment member according to the present invention is intended to facilitate attachment of two elements in an adjacent position to each other against a supporting section having a groove, defined by two towards each other directed parts, said elements including towards each other directed flange-shaped parts, and is mainly characterised in that the attachment member includes a central portion, adjacent to a first end portion being joined to an end part, extending in a plane separated from the plane in which the central portion is arranged extending and having a width exceeding the width of the groove, the portion located adjacent to the central portion being arranged with a width not exceeding said width of the groove, and the central portion in an area adjacent to the transformation point into the end part being arranged with from each other directed engagement members, and with an abutment member extending from a second end portion, said end part after insertion into the groove being arranged to take up contact against the inside surfaces of the parts defining the groove, and the abutment member, when moved towards the groove by means of force application, being arranged to facilitate insertion into a contact position against an inner surface of said parts defining
  • the abutment member is arranged extending in an inclined direction in relation to the direction of extension for the central portion, having a in direction from the central portion located part arranged separated from a center axis extending through the central portion with a distance that is not smaller than half the width of the groove, at least one portion of said part being arranged to serve as contact portion after insertion into the groove, and that the portion of the abutment member intended to take up contact with the internal surface of one of the parts defining the groove, is arranged pointed.
  • the abutment member is preferably arranged extending in an inclined, or substantially perpendficular plane, in relation to the plane of extension for the central portion.
  • an attachment member preferably manufactured from a metallic strip material by means of a punching and shaping tool.
  • Said attachment member includes a central portion 1, adjacent to a first end portion being transformed into a preferably plane end part 2, extending in a plane separated from the central portion 1, and having a width exceeding the width of the central portion 1.
  • an abutment member 4 In direction from the second end portion of the central portion 1 extends an abutment member 4, extending in a plane preferably substantially perpendicular to the plane of the central portion 1.
  • the abutment member 4 is joined to the central portion 1 by means of a folded outside edge portion, and the abutment member 4 is further arranged having an inclined direction of extension in relation to the direction of extension for the central portion 1.
  • the central portion 1 is arranged having a curved cross-sectional configuration, the outer edge portions being located at a larger distance from the end part 2 than the part located between the edge portions.
  • the two engagement members 3, 3' are also arranged shaped curved, and with the outer pointed portions thus being directed towards a plane located below.
  • the attachment member according to the present invention is intended to facilitate attachment against a supporting section, including a groove defined by two parts directed towards each other.
  • a supporting section 5 is shown in Figs. 6 - 8, having a plane of attachment including a centrally located groove 6 between two towards each other directed parts.
  • two panel shaped elements 7, 7' are shown, attached by means of the previously described attachment member.
  • the panel shaped elements 7, 7' are arranged with a longitudinally extending mounting flange 8, 8' at the adjacently located edge portions, said mounting flanges 8, 8' being located adjacent to the planes of the panel shaped members 7, 7' which act as contact planes against the supporting section 5.
  • a special purpose mounting tool is advantageously used, which facilitates temporary attachment of the panel shaped elements 7, 7' in intended position.
  • Said tool includes preferably a distance setting means, causing correct positioning and internal distance between the panelshaped elements 7, 7' in relation to the groove 6, but also means which can engage with the supporting section 5 and hold the panelshaped elements 7, 7' pressed against same.
  • a suitable number of attachment members are thereafter applied at spaced locations along the supporting section 5, each attachment member being inserted into the groove 6 with the end part 2 extending in substantially the same direction as the direction of extension for the groove 6.
  • the abutment member 4 serves as an extremely suitable part to be held by the fitter during the attachment operation.
  • the attachment member is turned, until the central portion 1 extends in a direction substantially corresponding to the groove 6.
  • the restricting parts for the groove 6 in the supporting section located in a position intermediately located between the end part 2 and the edge portions of the engagement members 3, 3' adjacent to the end part 2, but with the engagement members 3, 3' arranged with the outer and pointed portions in contact with the mounting flanges 8, 8'.
  • the distance from the edge portion of the end part 2 to the pointed free end portions of the engagement members 3, 3' must be arranged preferably slightly less than the total wall thickness of the supporting section 5 and the mounting flange 8, 8', and the outer end portion of the abutment member 4 should preferably be located above the plane in which the aforementioned edge portion of the end part 2 is located.
  • the central portion 1 is preferably arranged having a width corresponding to, or slightly less than, the width of the groove 6, and due to the cross-sectional configuration of the central portion 1, same will be substantially completely located in a plane below the contact plane of the supporting section 5.
  • the abutment member 4 may further advantageously be arranged extending in a plane inclined in relation to the plane of the central portion 1, whereby the upper point of the outer portion of the abutment member 4, intended to take up contact with the section 5, becomes located at a larger distance from the center of the central portion 1 in relation to a lower point at the outer portion.
  • the final part of the attachment operation for the attachment member is simplified, since the abutment member 4 does not require to be subjected to a transversely directed force when inserted into the groove 6, but it will "search" itself into the groove 6 when a force directed towards same is applied.
  • the attachment member By arranging the central portion 1 having the previously discussed cross-sectional configuration, the attachment member will substantially completely be located in plane coinciding with, or below, the attachment plane of the supporting section 5. As a result, a protective covering strip can easily be attached in the gap between the panel shaped members 7, 7-.
