Definitions

  • the invention relates to a locking arrangement for an openable door, window or hatch and an openable door, window or hatch using such locking arrangement.
  • the balcony glazing is arranged on a supporting stand which is mounted between a lower balcony slab and, arranged straight above the same, an upper balcony slab.
  • the supporting stand has an upper horizontal frame part, a lower horizontal frame part and two vertical frame parts.
  • the horizontal frame parts constitute guide rails and carry between them a plurality juxtaposed vertical glass doors which are laterally movable. Each glass door is movable back and forth along a rectilinear path between a first end position where they together cover the front side of the balcony along its entire width, and a second position in which they are arranged in a partly overlapping relationship whereby the front side of the balcony is maximally open.
  • the glass doors are pivotally arranged in view of the guide rails to allow e.g. cleaning.
  • the pivoting is provided by an arrangement which is integrated in a frame of the glass door, where a vertically extending pin is displaceable along the vertical direction in and out of engagement with the guide rail.
  • One pin is arranged in an upper horizontal edge portion of the glass door and one pin is arranged in the lower horizontal edge portion of the glass door.
  • the two pins are operable simultaneously by a so called espagnolette type locking arrangement.
  • the locking arrangement disclosed in SE 529745 C2 comprises a centrally arranged rotatable connector connected to two vertically extending shafts. The ends of the two shafts are pivotably mounted to the connector on diametrically opposing sides of the rotatable connector.
  • the connector may be operable by e.g. a handle or key that is arranged to engage the connector through a vertical side portion of the inner frame of the respective door.
  • the frame accommodating the locking arrangement must be wide enough to accommodate the connector.
  • the width of the frame has a direct impact on the available free window area, which should be as large as possible. Accordingly, the prior art solution relies on a lever mechanism where the lever is determined by the radius of the connector. Thus, to safe guard that the force required to rotate the connector and hence operate the locking arrangement can be provided, the connector must not be made too small since its radius constitutes a lever.
  • the main object of the invention is to provide a locking arrangement which requires a reduced space in the frame.
  • Another object is to provide a robust locking arrangement.
  • a locking arrangement for an openable door, window or hatch comprising: a first gear rack connected to a first end portion of first shaft having a longitudinal extension as seen in a first direction; a second gear rack connected to a first end portion of a second shaft having a longitudinal extension as seen in a second direction opposite the first direction; the first and second gear racks being received and guided along the interior of a longitudinally extending frame member; a gear wheel arranged between and in a driving engagement with the first and second gear racks; a handle being configured to be set between a locking position and an opening position by the handle being rotated about a pin which is arranged inside the interior of the frame member; an arm being articulately connected to the handle via a first pivot arranged at a distance from the fixedly arranged pin and articulately connected to the first gear rack via a second pivot, whereby the first gear rack is configured to be displaced in the second direction and the second gear rack is configured to be displaced in the first direction in response to the handle being set from
  • a locking arrangement in which all parts which are to be housed in the frame member of the openable element are substantially linearly operated.
  • the locking arrangement is less bulky.
  • the width of the frame member as seen in the main extension plane of the openable element may be reduced. In practice this means that in the event of the openable element being a framed window, the window area may be made larger than with prior art solutions. This is of special importance in a balcony glazing where the framing should be made as small and visually insignificant as possible.
  • the locking arrangement comprising a handle which is integral with the locking arrangement, there is no risk of essential parts being lost, such as a removable key.
  • the pivot that is formed by the pin will be concealed and protected from the ambience.
  • a free end of the arm associated with the second pivot may be configured to be received in a longitudinally extending cavity formed inside the frame member in a position when the handle is set in the locking position.
  • the cavity may be formed by the first and second gear racks being longitudinally displaced in response to the handle being set from the opening position to the locking position
  • the second pivot may be configured to be arranged inside the frame member when the handle is set in the locking position and configured to be arranged outside the frame member when the handle is set in the opening position.
  • a free end of the second gear rack may be configured to abut a stop portion of the first gear rack in a position when the handle is set in the opening position. Thereby a physical stop is provided for which prevents further mutual displacement of the gear racks and hence also further displacement of the shafts in view the guide rails.
  • the first and second gear racks may comprise complementary guiding surfaces configured to form interacting sliding surfaces during longitudinal displacement of the first and second gear racks in the first and second directions.
  • the first and second gear racks may be slidingly supported by inner wall portions of the frame member during longitudinal displacement of the first and second gear racks in the first and second directions.

  • the end of the arm 102 must be forced to pass the shoulder 142. This may be provided for by overcoming an inherent elasticity in the engaging parts. Accordingly, the operator must actively force the arm 102 by operating the handle 101 to pass the shoulder 142 in order to set the locking arrangement to its open position.
  • the locking arrangement 100 is illustrated in an intermediate position between the locking position and the opening position.
  • the handle 101 has been pivoted in a direction away from the frame member 200, see arrow A.
  • the handle 101 is pivoted around the pin 114. Since the handle 101 is also indirectly connected to the arm 102 via the second pivot 116, the handle 101 pulls the associated end of the arm 102 out from the first longitudinally extending cavity 133. This is allowed as a result of the opposite end of the arm 102 being articulately connected to the first pivot 115 which is integral with first gear rack 104.
  • the arm 102 displaces, by a pulling action, the first, lower, gear rack 104 in a second direction, see arrow B, towards the support member 103.
  • This is allowed by the first gear rack 104 being slidingly received in the frame member 200.
  • the first gear rack 104 is arranged in a driving engagement with the second gear rack 105 via the intermediary gear wheel 106
  • the second gear rack 105 is displaced in the opposite direction, see arrow C, by being slidingly received in the frame member 200.
  • the first and second gear racks 104, 105 are in direct driving engagement with each other via the intermediate gearwheel 106, the first and second gear racks 104, 105 are displaced the same distance and with the same speed.
  • a ratio 1:1 applies in terms of displacement and speed for the two gear racks 104, 105.
  • first and second gear racks 104, 105 continue until the handle 101 has been set to its fully opened position, see Fig. 6. In this position, the first and second gear racks 104, 105 have been mutually displaced to such extent that the free end of the second gear rack 105 opposite the engagement portion 119 abuts a mating stop portion 143 of the engagement portion 119 of the first gear rack 104.
  • the gearwheel 106 may have reached an end of the toothed portions 123 in which it is prevented from further rotation around its shaft 160.
  • the locking arrangement has been described and illustrated based on a frame member where the handle is arranged on one of the two side walls that extend substantially perpendicular to the surface extension of the openable element, and where the inner side walls of the other set of opposing side walls act as sliding and guiding surfaces for the first and second gear racks.
  • the frame member may be redesigned within the scope of the invention so that the gear racks are configured to be guided and slid along the other set of opposing side walls of the frame member.
  • the handle may be supported by another side wall of the frame member than exemplified above.
  • the locking arrangement has been described as arranged with the handles projecting from a side wall portion extending transverse the major plane of the openable element with the shafts extending along the vertical extension of the frame member. It is to be understood that the locking arrangement may be arranged in other orientations and in other surfaces of an openable element. The locking arrangement may by way of example be equally applicable in the event the shafts have a horizontal extension.
  • the locking arrangement has been described as applied to an openable element of a balcony. It is to be understood that the locking arrangement is also applicable in other applications such as a sliding window arrangement, a door, a window or a hatch.

Abstract

L'invention concerne un agencement de verrouillage pour une porte, une fenêtre ou une trappe pouvant être ouverte. L'agencement de verrouillage comprend une première crémaillère d'engrenage (104) possédant une extension longitudinale telle que vue dans une première direction C et une seconde crémaillère d'engrenage (105) possédant une extension longitudinale telle que vue dans une seconde direction B opposée à la première direction C. Une roue dentée (106) est disposée entre les première et seconde crémaillères d'engrenage et entre en prise d'entraînement avec celles-ci. Une poignée (101) est configurée pour être placée entre une position de verrouillage et une position d'ouverture par rotation. La première crémaillère d'engrenage (104) est conçue pour être déplacée dans la seconde direction B et la seconde crémaillère d'engrenage (105) est conçue pour être déplacée dans la première direction C en réponse au passage de la poignée (101) de la position de verrouillage à la position d'ouverture. L'agencement de verrouillage peut être utilisé dans un balcon vitré, un agencement de fenêtre coulissante, une porte, une fenêtre ou une trappe.
