Definitions

  • the invention concerns a method of installation of a roller blind, in particular located on the outer side of a building, including mainly placing and mounting of a cassette with a rolled up blind at the window head.
  • the invention concerns also a roller blind assembly with its guide rails.
  • the solution according to the invention is applicable in the construction industry.
  • Roller blinds are known, for instance from PL 200 782 , that have a cassette or a box at the top, accommodating a roller with a rolled-up roller blind panel and a spring gear driving this rolling, having also side guide rails in the form of sections open towards the roller blind panel, where pins protruding from the roller blind panel move near the panel bottom edge.
  • the box accommodating the rolled-up roller blind panel is situated over the top ends of the guide rails, and its dimensions exceed the external span of these guide rails.
  • the design and the resulting method of the roller blind installation require first the cassette to be placed and fixed at the window head. It is inconvenient, as one must hold the cassette installed with raised hands at the same time fixing it in this position. Moreover it is dangerous if the roller blind is installed at windows on higher floors of a building.
  • the method of roller blind installation according to the invention in particular of an external roller blind, with the main objective to place and fix a cassette with the rolled-up blind in the vicinity of the top part of a window, in particular on the outer side of a building, consists in that in the first assembly stage the roller blind guide rails are mounted at the window, whereas in the main stage of the assembly, the cassette is put into the guide rails near their bottom end, next the cassette is shifted up, where it is at least initially located with snap fixtures, restraining the cassette vertical movement.
  • the roller blind guide rails during their normal operation are to maintain the path of the bottom roller blind edge movement during its unrolling and rolling, during the assembly they additionally serve for guiding the cassette installed.
  • the guide rails are mounted in the window opening in the building wall, secured to the window frame.
  • the guide rails may also be placed outside the window opening, in its immediate vicinity, and in this case they are secured to the external surface of the building wall. They may also be placed in the window opening in the wall and secured to the side surfaces of this opening.
  • the cassette installed with the roller blind rolled up inside and with the gear for rolling and unrolling the blind has fastening blocks, which move in the roller blind guide rails.
  • the main stage of assembly starts with putting the fastening blocks into the guide rails, next they are shifted to the top position, in which the cassette is located at the window head, inside or outside the window opening, in accordance with the guide rail position. In this top position the cassette is at least initially located with snap fasteners.
  • the snap fasteners advantageously in the form of spring catches are mounted together with the guide rails as component parts of the guide rails.
  • the snap fasteners in the form of a catch, are located inside the guide rails.
  • the catching surfaces in the cassette cooperating with these spring catches are situated in the cassette fastening blocks.
  • the guiding block having a hollow space inside has in its top wall a hole for the catch situated in the guide rail, and the catching surface of the block is the inner surface of its top wall in the vicinity of this hole.
  • the catch fasteners are installed at the first stage of assembly on the outer side of the guide rails, in particular after mounting the guide rails in the window opening.
  • the snap catches installed at the guide rails cooperate with catch surfaces in the cassette, which may be the surfaces of holes in the side or end walls of the cassette, or the external bottom surface of the cassette.
  • the snap fasteners are connected to the cassette containing the roller blind.
  • the snap fasteners are placed at the bottom of the guide rails, along with the cassette fastening blocks.
  • the cassette with its fastening blocks and the snap fasteners is shifted up, and having reached the cassette top position, the snap fasteners catch the top edges of the guide rails.
  • Catching the cassette containing the rolled-up blind in its top position with the snap fasteners has basically the aim of initially restraining the cassette.
  • the task of this initial catching is to facilitate the final setting of the position of the cassette and to secure it in the position expected for normal use of the roller blind.
  • One of the variants of the final method of locating and securing the cassette in its top position consists in that the cassette, after its initial location with the snap fasteners, is supported with a pressure block put from the bottom into the guide rail, this block is placed in the guide rail directly under the cassette fastening block.
  • a bumper is placed, which restricts the fastening block and the whole cassette movement up, and the cassette fastening block is pushed to this bumper with the pressure block, while initial assembly clearances are eliminated.
  • the pressure block is fastened in its final position in the guide rail, using the friction, and the pressure force of the frictional surfaces is obtained with at least one threaded fastener.
  • the second variant of the method of final setting and fastening of the cassette in its top position consists in that after the initial catching of the cassette with snap fasteners it is located in the top position with intermediate fasteners, advantageously with threaded fasteners.
  • the intermediate fastener for locating the cassette may be a vertically situated bolt, screwed into a threaded hole in the stopper closing the guide rail from the top. These bolts may be situated also on the cassette section between the guide rails.
  • the intermediate fastener for locating the cassette may also be a pin, fastened horizontally in the guide rail, going through a hole in the cassette fastening block or adjoining the cassette fastening block from the bottom.
  • a roller blind assembly with its guide rails being the object of the invention has a cassette with a roller for rolling and unrolling the blind, and guide rails, maintaining the movement path of the roller blind bottom edge during its unrolling and rolling, and its main characteristics is that each guide rail, being an open section, with the main niche for guiding the pins of the bottom edge of the blind, has a lengthwise positive fastening unit for the subassemblies mounted in the guide rail, and the cassette has end walls on both sides, each with a fastening block, entering the main niche of the guide rail.
  • the fastening blocks are seated in the guide rail with a clearance enabling free movement of the blocks and the complete cassette along.
  • a snap fastener is installed, in particular in the form of a catch cooperating with the catch surface in the cassette end wall fastening block.
  • the blind roller assembly with the guide rails is installed in the window opening in a building wall on the outer side of the window, and the guide rails are advantageously secured to the window frame.
  • the cassette with the roller blind there is a spring gear driving the rolling of the roller blind on the roller, and there are interlocks in the guide rail for stopping the roller blind at least in its fully unrolled position. They have the form of catching blocks, with seats for pins protruding to the sides from the roller blind at its bottom edge.
  • a lengthwise positive fastening unit In the guide rail main niche on its entire length there is a lengthwise positive fastening unit, its main part having the form of a fastening channel, limited with two projections in the guide rail section having a profile of angle sections, protruding from one of the guide rail walls to the main niche.
  • the walls of the angle section projections parallel to this guide rail wall are facing each other, and between them there is a slot, through which bolts fastening the sub-assemblies seated in the guide rail inside the guide rail go. These bolts cooperate with nuts, advantageously square ones, placed in the fastening channel.
  • the lengthwise positive fastening unit has a single catching angle section shaped projection, with the grip wall advantageously facing the main niche of the guide rail.
  • the subassemblies installed in the fastening channel and additionally with the catch projection have grooves overlapping the grip wall of the catch projection.
  • the snap fastener for the cassette located in the upper part of the guide rail has the form of an elastically bent out catch, and at its base it is monolithically connected to the top stopper with the shape filling the main niche of the guide rail, fitted with a circumferential shoulder, resting against the guide rail face.
  • the top stopper is secured to the guide rail with a bolt, having its nut placed in the fastening channel.
  • the top stopper may also have a groove, slid over the grip wall of a single catch projection.
  • Below the cassette fastening block there is a pressure block in the guide rail, fastened to the guide rail with at least one bolt with the nut placed in the fastening channel, advantageously with a groove slid over the grip wall of the guide rail catch projection.
  • a pressure tapered key protrudes upwards from the pressure block, inserted into a key-slot in the cassette fastening block.
  • An analogous tapered key protruding up from the cassette fastening block is inserted into a key-slot in the top stopper.
  • the fastening block has a limiter, situated so that together with the main surface of the end wall, they encompass the guide rail catch projection from both sides.
  • the limiter prevents an excessive shift of the cassette during its assembly towards one of the guide rails, and thus against sliding of the fastening block out of the opposite guide rail.
  • the fastening block of the cassette end wall has also an elastic bumper, adjoining the bottom of the guide rail main niche with its end. The task of the two bumper set, situated at both ends of the cassette in its end walls, is to centre the cassette installed, between the two guide rails.
  • Each of the catch blocks mounted in the guide rails has a socket, accessible from the roller blind side and from the bottom, for pins protruding from both sides of the roller blind at its bottom edge.
  • the pins protruding from the roller blind are the endings of a rod, advantageously round, situated in the roll-up of the bottom edge of the roller blind.
  • the catch block is fastened to the guide rail with a bolt with the nut placed in the fastening channel, and advantageously having a vertical groove, slid over the grip wall of the guide rail catch projection.
  • the guide rail has a web facing its main niche, advantageously perpendicular to the pin protruding from the roller blind.
  • the web maintains an appropriate distance between the blind roller pin and the guide rail wall, preventing rubbing the pin against this wall, thus protecting paint coatings of the guide rail from damage.
  • the distance between the face of the web and the ridge of the catch block is slightly longer than the thickness of the pin, which enables it to be moved in the guide rail near the catch block.
  • catch blocks There are two varieties of catch blocks: an end block, for catching the roller blind in its maximum unrolled position, and intermediate blocks, for catching partially unrolled roller blind.
  • the end catch block is monolithically connected to the bottom stopper, having the shape filling the guide rail main niche.
  • the bottom stopper has a circumferential shoulder, resting against the bottom face of the guide rail, which locates the position of the end catch block near the bottom end of the guide rail.
  • Any number of intermediate catch blocks may be mounted in places of the guide rail selected by the user.
  • the socket for the roller blind pin has a throat in its upper section. It prevents a self-release of the roller blind pin from the socket it is seated in. Under the throat, the entry to the socket is widened, which facilitates inserting the roller blind pin into the seat.
  • the function of setting the roller blind in its upper position is performed by the pressure blocks, which have a concave bearing surface for the roller blind pin. It is the operating position of the roller blind, whereas during assembly the roller blind adjoins the cassette surface with its rod.
  • the pressure block has an elastic latch, which when bent enables the pin protruding from the blind to be moved down so that it is below the pressure block. It is performed after installing the cassette in its top position and setting it with the pressure block.
  • the pressure block latch has an inclined surface at the bottom, which is an extension of the bearing surface for the roller blind pin, which guides the pin, during its movement upwards, onto the concave bearing surface of the pressure block.
  • the roller blind fabric of limited light transmittance and weather proof plastic, has in its lower part a roll-up in which the rod ended with pins, shifted in the guide rails and located in the catch blocks, is seated. In its bottom edge the fabric has cut-outs exposing the rod locally, so that it can be used as a handle for shifting the roller blind.
  • the threaded fastener subassemblies consisting of a bolt and nut, used for fastening the subassemblies seated in the guide rail, the nuts are square, and the pressure block, the catch blocks (the end one and the intermediate one) and the top stopper have two limiters each, entering the slot of the fastening channel, adjoining the nut side surfaces from the top and from the bottom.
  • the fastening node of the indicated subassemblies is characterised by that the pressure block, catch blocks and the top stopper have spacers, situated under the nut bearing surface.
  • the spacer height slightly exceeds the thickness of the fastening channel wall, therefore there is a clearance under the nut, which facilitates inserting the subassemblies into the guide rail.
  • the strength of the spacers is selected so that they are easily crushed when the bolt is screwed into the nut, therefore their presence does not diminish the efficiency of fastening of the subassemblies placed in the guide rail during normal operation of the roller blind.
  • An advantageous effect of the invention is easy and safe installation of the roller blind assembly on the outer side of a window, in particular installation of a cassette with the roller blind rolling gear, put on from the bottom and next shifted in the guide rails and caught with snap catches at the top. Also the support of the nuts with spacers facilitating inserting of the nuts into the fastening channel from the bottom is advantageous.

  • the guide rail 3 has two webs 36, facing its main niche 31, perpendicular to the pin 23 ending the roller blind rod.
  • the distance between the face of the web 36 and the ridge 73 of the intermediate catch block 7 is slightly longer than the thickness of the pin 23, which enables it to be moved in the guide rail near the catch block. Identical dimensions and clearances concern also the end catch block.
  • the intermediate catch block 7 has a horizontal port, through which a hexagon socket cap bolt 8 goes.
  • the limiters 82 locate the position of the nut 81 (preventing uncontrolled turn) before it is inserted into the fastening channel 32.
  • the spacers 83 protruding from the intermediate catch block 7, with their height exceeding the thickness of the projection 33 walls.
  • the task of the spacers 83 is to maintain the distance of the nut 81 to the intermediate catch block 7, and thus to maintain the assembly clearance, before they are slid into the guide rail 3.
  • the spacers 83 are crushed and the nut 81 starts to cooperate with the walls of angle section shaped projections 33, maintaining the location of the intermediate catch block 7 with friction forces.
  • the intermediate catch block 7 has also a vertical groove 74, slid over the grip wall 35 of the catch projection 34 of the guide rail (drawing - fig. 6 ), this positive connection, in cooperation with the bolt 8 and nut 81, ensures stable mounting of the intermediate catch block 7 in the guide rail.
