Definitions

  • the invention relates to a locking device for locking an extendable and retractable blind, shade or awning in its extended position
  • Such blinds, shades or awnings can have a rotatably mounted roller around which a suitable flexible sheet like material, including cloth, fabric, curtain or screen material, is wound.
  • a free end of such wound sheet like material, opposite the roller, is attached to a movable beam which is movably engaged, at its longitudinal ends, in side guide tracks arranged on opposites lateral sides of the sheet like material.
  • Such blinds shades or awnings amongst others are known from EP 0305081 or EP 0957230.
  • a particular difficulty with these known arrangements is that the locking devices are symetrically duplicated on the relevant opposite lateral sides of these blinds, shades or awnings and as a consequence have to operate simultaneously.
  • gusts of wind can interfere with the simultaneous operation of the locking devices on either lateral side.
  • the blinds, shades or awnings have occasionally only locked on one lateral side or even more serious the repetitive sequential operation of the locking mechanism has become disordered. It is an object of the present invention to prevent such possibly inconvenient mishaps.
  • the invention provides for a locking assembly for releasably holding a movable end bar of an extendable and retractable blind, shade or awning, having such an end bar mounted for translation along opposite lateral guide tracks, wherein the locking assembly includes a first part associated with the lateral guide track at a stationary position thereof and a second part associated with the movable end beam engageable with and disengageable from the first part upon inverting the movement of the beam from a first direction of movement to a second direction of movement, wherein the first part comprises a first locking body at a first of the lateral guide tracks and a second locking body at a second of the lateral guide tracks and wherein the first locking body is different from the second locking body.
  • Figure 1 shows a roller shade like structure 1 for application on the exterior side of building windows.
  • shade-like structures are sometimes referred to as vertical awnings, which expression will be used throughout this specification. It should be understood however that such a structure need not be vertical, but can also be arranged in a slanted or even horizontal plane if the necessary adaptations are made to ensure that it can be extended and retracted. Also the arrangement need not be confined to exterior applications alone, but could be similarly effective for indoor mounting
  • Figure 1 shows the vertical awning in its extended position with a sheet-like screening material member 3 covering a surface defined by opposite left and right hand guide tracks 5 and 7 and a head box 9.
  • the head box 9 accommodates a retraction mechanism such as a roller (not shown, but conventional) to which one edge of the screening material 3 is attached and onto which it can be wound to a retracted position.
  • a retraction mechanism such as a roller (not shown, but conventional) to which one edge of the screening material 3 is attached and onto which it can be wound to a retracted position.
  • a beam 11 which is movably guided in a vertical direction along the opposite guide tracks 5 and 7.
  • a first locking member 13, in the form of a guide track bottom element is positioned at a bottom end of the left hand side track 5 and a second locking member 15 is arranged at a bottom end of the right hand side track 7.
  • FIG 2 shows the side guiding tracks 5 and 7, the first and second locking members 13 and 15, as well as the movable beam 11 in an exploded arrangement, so as to show additional elements that would practically be hidden from view in the assembled arrangement of Figure 1.
  • Each longitudinal end of beam 11 is provided with an end member to guidingly engage the relevant side track.
  • a first end member 17 engages the left hand track 5 and a second end member 19 engages the right hand track 19.
  • the first and second end members 17, 19 are attached to the movable beam 11 by means of screws 21 and 23 respectively.
  • a boss 25 (27 on the second end member) is made to rotatably fit snugly between front and rear edges of a longitudinal slot 29 and 31 respectively in each of the left and right hand guide tracks 5 and 7 respectively.
  • An upper longitudinal edge of beam 11 is provided with a longitudinal groove 33 to receive a free bottom edge of screen member 3 (deleted for clarity from Figure 2).
  • first and second plug elements 35, 39 and 37, 41 respectively are forced in from both longitudinal ends of groove 33 to engage a screen rod 43 which will be accommodated in a bottom hem to the screen material (not shown).
  • the purpose of the expanding plug elements is to inhibit any possible movements between the screen 3 and the beam 11 when assembled. This arrangement is only given as an example and the skilled person will be aware of alternative solutions to unmoveably arrest the screen material 3 in respect to the beam 11.
  • a pin 45 Spaced below the respective boss 25 of first end member 17 is inserted a pin 45 to extend laterally from the first end member.
  • a similarly laterally extending pin 47 is correspondingly inserted in the second end member 19.
  • Figure 3 shows a left hand end portion of beam 11 with the left hand or first end member 17 and screen 3 attached thereto.
  • the guide track 5 is only shown in dotted lines, with the first locking member 13 shown in full and immediately below the beam 11, as it would be when the screen 3 is almost fully extended.
  • the laterally extending pin 45 is projecting from the end member 17 to extend parallel to boss 25 and well into the interior of the guide track 5.
  • the boss 25 has a cylindrical stem portion 49 and a retaining flange 51.
  • Retaining flange 51 would prevent the boss 25 to escape from slot 29 in the guide track 5.
  • the second end member 19 is preferably made identical to the first end member 17 and a further description will thereby be redundant.
  • the cylindrical portion 49 will have a diameter which very closely approaches the lateral dimension of the guiding slot 29 in guide track 5.
  • the cylindrical portion 49 preferably also is of such a length to allow the beam 11 to move away to some extent from the guide track 5, to compensate for any inaccuracies in the parallelness of the opposite guide tracks 5 and 7 when installed on a building.
  • the flange 51 will limit the length of the cylindrical portion 49 and prevent its escape from the guide track 5 and thereby limit the extent of movement allowed.
  • the laterally extending pin 45 is of a substantially smaller diameter than the cylindrical portion 49 so that it may move from a front edge of slot 29 to a rear edge thereof. The fore and after movement of pin 45 will allow the beam 11 to tilt, to a certain extent, around the cylindrical portion 49.
  • Figure 4 is a transparent view taken in the length direction of beam 11, with the side guiding tracks 5 and 7 in overlapping arrangement, as seen from outside the left hand guide track 5.
  • the reference numerals in Figure 4 will generally refer to the left hand guide channel 5 and its locking member 13, but should be understood to have equivalent relevance to the right hand side guide 7 and locking member 15, which are somewhat hidden in the view of Figure 4, except where stated to be different.
  • the slot 29 (and likewise the slot 31 in the other guide track) has a rear edge 52 and a front edge 53, between which the cylindrical portion 49 of boss 25 is vertically slidably and rotatably retained.
  • the lower extending pin 45 has a substantially smaller diameter and can be forwardly and rearwardly deflected between the front edge 53 and rear edge 52 of the slot 29
  • the beam 11 will normally take a vertical position, aligned with a centre line 55 of slot 29.
  • Figure 4 shows the beam 11 in a tilted position, with the extending pin 45 deflected towards the front edge 53 of slot 29.
  • first or left hand locking member 13 has a first locking body 57 and the second or right hand locking member 15 has a second locking body 59.
  • Each of the first and second locking bodies 57, 59 has an apex 61, 63 formed at an upper end thereof.
  • the first and second apexes 61, 63 are each reardwardly spaced from centre line 55 at a distance 65 which is about equal or slightly greater than half of the diameter of the extending pin 45 (and 47). This ensures that with the lowering of beam 11 for the extension of the screen or sheet member 3, both of the extending pins 45 and 47 will be positioned in front of forward sloping surfaces 67 and 69 of the first and second locking bodies 57, 59.
  • th pins 45 and 47 Upon further lowering of beam 11, th pins 45 and 47 will reach a forward edge 71 and 73 on each of the relevant left and right hand forward sloping surfaces 67 and 69. Only on the right hand locking member 15 there is a guiding hump 75, which prevents the right hand extending pin 47 from returning to the centre line 55 if lowered below the forward edge 73 of the right hand locking member 15. A rearward sloping surface on hump 75 guides pin 47 into recess 77 at the bottom of the second locking body 59 when movement of beam 11 is reversed from lowering into raising. The entire beam 11 and left hand extending pin 45 will follow this movement and similarly lock into a recess 79 provided on the bottom end of the first locking body 57.
  • Each of the locking bodies 57 and 59 may be provided with a sloped rear surface 83 and 85 respectively to guide each of pins 45 and 47 over the apexes 61 and 63 respectively upon retraction of the sheet material 3 and beam 11. From a comparison of Figures 5 and 6 it will further be apparent that the bottom recess 79 of the first locking body 57 is less deep than the bottom recess 77 of the second locking body 59. This is intentional to ensure that no locking of pin 45 shall occur when pin 47 is unlocked from recess 77.
