Definitions

  • Title A device for securing a rail onto a supporting structure such as a wall.
  • the invention relates to a device for securing bars and rails such as hand rails and the like onto a supporting structure such as a wall.
  • a typical example of the use of the present invention is securing of hand rail structures in housing for the elderly and the like residential homes, for instance in corridors and bath rooms.
  • the invention relates to a device for securing a rail onto a support ⁇ ing structure such as a wall and comprising a slitted ring member adapted to circum ⁇ scribe the rail in a retaining manner and provided with a protruding leg on each side of the slit, and a clamping means adapted to clamp the legs together and thus retaining the ring member in engagement with the rail.
  • DE 36 04 326 discloses a device of the above type which adjacent the outer ends of the legs is provided with a recess adapted to be brought into retaining engagement with the head of a screw screwed into a wall when the legs and thus the ring member are clamped together by means of the transverse clamping means formed of a screw/nut connection.
  • the legs of the ring member are clamped to the fastening members at the same as the ring member is clamped around the rail. This causes the device to be sensitive to the tolerances of the rail.
  • the ring member is made of a comparatively rigid material such as aluminium, for which reason it is necessary to insert the ring member onto the rail from one of end thereof.
  • US-A-1, 096,282, US-A-2,896,899, US-A-3,023,992 and FR-A- 1.104.928 all disclose various types of devices for securing rails onto a wall. These devices are however, all encumbered with various drawbacks, e.g. they comprise a comparatively large number of parts, are difficult to mount or have very limited applications.
  • the object of the invention is to provide a device of the above type of a simple structure and which is easy to mount and has many applications.
  • the device according to the invention is characterised in that the ring member is formed integrally of plastic and of such a flexibility that it may be expanded to receive the rail through the slit and that the device further comprises a fastening member for securing the device onto the supporting structure through a first leg.
  • the ring members of all of the devices necessary to support a rail can be secured to the supporting structure by means of the intended fastening means and the rail subsequently connected to the ring members by expanding the ring members, inserting the rail into the ring members through the slit and subsequently tightening the clamping means.
  • devices may be mounted subsequently without dismounting the complete rail, if additional devices are needed to fasten the rail securely.
  • the device is of a very simple structure and may be mass produced rationally by injection moulding the ring member in its expanded position.
  • the ring member is of such a flexibility that it may be expanded such that the legs are essentially perpendicular to each other. As a result, the subsequent mounting of an additional device between two devices supporting a secured rail is facilitated.
  • the first leg is provided with an axial hole opening into an outer end face of the leg and adapted to receive a fastening means comprising a screw, which is passed through the axial hole from its end situated opposite the outer end of the leg.
  • the device is thus mounted on the wall by screwing the screw into the wall.
  • the fastening means comprises a thread situated adjacent the axial hole.
  • the first leg in the side the first leg may be provided with a first recess to receive the second leg, the second leg thus being within the outer outline of the first leg.
  • this recess communicates with the interior of the ring member.
  • the two legs have co-acting guide means to guide said legs into the position in which the ring member circumscribes the rail in a retaining manner.
  • a second recess may be provided in the side of the first leg more closely to the outer end of said leg than the first recess and adapted to receive a screw head or a nut and communicating with the axial hole and that an abutment face for the screw head or the nut may be arranged around the opening of the axial hole in the second recess.
  • the two recesses may be provided on the same side of the leg, one recess continuing axially into the other.
  • This embodiment of the invention is particularly advantageous when the fastening means is formed of a hexagon socket head screw, as it thus is possible axially through the recesses to bring an Allen key into engagement with the socket hexagon of the screw in the open position of the ring member.
  • the second recess may be provided with inner surfaces adapted to prevent a head of a hexagon head screw or a hex-nut from turning.
  • the head of a hexagon socket screw may be inscribed into the head of a hexagon head screw of the same size and thus also into the corresponding nut, this embodiment of the invention renders many options in the choice of fastening means .
  • the legs may jointly have an essentially circular, cylindrical outer outline.
  • one of the legs per se may have an essentially circular, cylindrical outline.
  • a covering sleeve may be pivotally arranged around the legs and provided with an opening allowing one of the legs to pass herethrough.
  • This embodiment of the invention is particularly preferable when the second leg is received in a recess in the first leg, the recess and the leg received therein being concealable by rotation of the sleeve.
  • the advantage of using a pivotal sleeve to conceal the recess instead of a plug being inserted into the recess is that a pivotal sleeve in contrast to a plug is not lost, if it becomes loose and is further secured against unwarranted removal.
  • the device may further comprise a flange member secured to the outer end of the first leg and provided with screw holes for screws to fasten the flange member and thereby the device to the supporting struc ⁇ ture.
  • a particularly reliable fastening to the supporting structure is obtained due to the flange member.
  • the flange member may be of an essentially rotationally symmetric shape and the screw holes may be arranged on a circle being concentric with the flange member, and an annular cover may be pivotally arranged on the flange member, said cover at least covering the screw holes and provided with an opening of such a size that the heads of the screws may pass herethrough.
  • the opening of the cover is turned so as to be in alignment with the hole in which the screw is to be mounted. When all of the screws have been mounted, the opening is turned away from the holes, whereby these are covered.
  • the annular cover has the above advantages of the sleeve for covering a recess in the leg.
  • Fig. 1 is an exploded view of a first embodiment of the device according to the invention, seen isometrically.

  • the ring member 1 is retained in the shown retaining and circumscribing position by means of a hexagon socket screw 14 extending through the hole 9 and engaging a nut 15 accommodated in a countersunk hole 17 on the outer face of the first leg 3.
