Definitions

  • the present invention relates to a method according to the preamble of Claim 1, and to apparatus according to the preamble of Claim 3.
  • a vertically movable shutter or door-like device hereinafter referred generally as a shutter
  • a shutter are normally received slidingly in essentially U-section guide rails, through the medium of hoist elements, e.g. hoist lines or belts.
  • the U-section guide rail includes engagement means for coaction with a latching mechanism that is intended to be mounted between a shutter hoist element, e.g. a shutter lifting line or belt, and brought into and out of latching engagement with said engagement means when relieving the latching mechanism of tension force or when applying tension force to said latching mechanism, through the medium of the hoist elements.
  • the shutter is rendered safe, e.g., by virtue of the free outer end of a movable pawl in the latching mechanism moving into latching engagement with recesses or notches formed in the bottom of the U-section guide rail, or into latching engagement with an elongated latching profile having a tooth-like configuration in cross-section and screwed to the bottom of the guide rail or fastened thereto in some other suitable manner.
  • the profiled sections used for the shutter-edge receiving guide rails i.e. for forming slide guides which receive the edges of a mounted shutter, door or corresponding device, and also other components, for instance the profiled sections used as frame components for defining the shutter edges, are conveniently produced by extrusion, e.g. the extrusion of aluminium.
  • extrusion e.g. the extrusion of aluminium.
  • One drawback with extruded profiled sections is that they can only be profiled in their longitudinal direction and not in their transverse direction, although this is necessary in order to provide the latching tooth-like configuration of the U-section guide rail.
  • the aforesaid recesses or notches be formed in the U-section profile in conjunction with the extrusion process, but must be formed, e.g. punched, in the profile in a subsequent manufacturing stage, which involves much more work and therewith greater manufacturing costs.
  • the object of the present invention is to provide a method whereby a U-section guide rail can be produced by extrusion together with a rail-associated toothed engagement element for coaction with a shutter latching mechanism whose active length can be readily varied.
  • the U-section guide profile and the engagement element can both be produced by extrusion, by extruding a U-section guide rail that has an undercut groove in the bottom wall of the rail, and by extruding an elongated profiled section that has a toothed-configuration in cross-section, and separating sections transversely from the profiled element with a width at which the separated sections can be fitted into, the undercut groove, and then inserting the thus formed individual sections sequentially in said undercut groove so as to form a continuous sequence of tooth-like engagement elements which face towards one edge of the movable shutter.
  • the active length of the engagement element sequence can be easily adapted by appropriate selection of the number of sections inserted into the undercut groove and their positions in a vertical direction.
  • the reference numeral 1 in Fig. 1 designates generally a shutter or corresponding door-like member (not shown in detail) whose edges 2 are provided with respective strips or frame parts that are guided in essentially U-section guide rails 3, said guide rails preferably being extruded from aluminium.
  • the upper part of the shutter 1 is suspended from a box-like housing which is mounted at the upper defining surface of the shutter opening and which includes a hoist mechanism including lines, belts or like devices connected to the shutter 1 and functioning to move the shutter up and down through the medium of the hoist mechanism, so as to open and close the shutter or door opening (not shown) respectively.
  • the shutter edges 2 are received slidably in the guide rails in a manner to restrict lateral movement of the shutter 1 as it is moved axially, or vertically.
  • the U-section guide rail 3 includes an engagement element 4 which coacts with a latching mechanism 5 such as to prevent the shutter 1 from falling unimpeded should one of the supportive lines break.
  • the engagement element is received in an undercut groove 6 formed by two mutually opposing projections 7, 7' which extend along the rail bottom wall in mutually spaced relationship and each of which terminates at a distance from the other so as to form an opening 8 in the bottom wall of the U-section guide rail 3.
  • the engagement element 4 includes latching teeth 9 which are accessible to a latching pawl 10 included in the latching mechanism.
  • the pawl 10 is pivotally mounted on a pivot shaft or pin 11 and the lower free end 12 of the pawl is able to engage a tooth 9 as said free end swings outwards from the shutter 1, as shown in Fig. 2.
  • the latching pawl is provided on one side thereof with a recess 13 through which the shutter supporting line passes.
  • the latching pawl is provided on the opposite side, above the pivot pin 11, with a coil spring 14 which endeavours to swing the free end 12 of the pawl 10 into engagement with the teeth 9 on the element 4.
  • the spring characteristic of the coil spring 14 is chosen so that the spring force will be balanced by the weight of the shutter, i.e. by virtue of the abutment of the hoist line with the latching pawl 10. If the hoist line should break, the latching pawl 20 will pivot in response to the spring force, so that the free end 12 of said pawl will engage the teeth 9 of the engagement element 4, as shown in chain lines in Fig. 2.
  • said element is constructed of a plurality of individual sections 13 which can be inserted sequentially into the undercut groove 6, 8 on the U-section guide rail 3.
  • all that is required is securement of the first and the last sections 13 in the groove 6, 8 in the U-section guide rail 3 in some suitable manner, for instance with the aid of screws.
  • the engagement element 4 is conveniently fabricated by extruding a profile blank, preferably an aluminium blank, into an elongated profiled element 15 having a toothed-configuration in cross-section for receiving the free end 12 of the latching pawl 10 of the latching mechanism 5 (Fig. 3). End parts are separated from the profiled element transversely thereto such as to form the aforesaid individual sections 13 having a width such as to fit into the undercut groove 6, 8 on the bottom wall of the U-section guide rail 3.
  • the extruded profiled element 15 is provided with grooves or recesses 16 along one longitudinally extending edge part thereof and with tongues 17 along the other longitudinally extending edge part of said element, these tongues and grooves being insertable into one another to assist in mutual connection of the individual sections 13 inserted into the groove 6; c.f. also Fig. 2.
  • the guide rail need not have a U-shaped cross-section, but may have any configuration suitable for receiving the edges of the vertically movable shutter or door-like member.
