Definitions

  • the present invention relates to securing and/or locking devices and/or methods used, for example, but not exclusively, for a pivotably openable window or like closure member, the securing/locking devices and methods being of a type having a magnetic securing and/or locking force to secure and/or lock a pivotably openable closure member within a stationary aperture frame, such as a pivotable window sash within a stationary window frame.
  • Pivoting windows, doors or other aperture closure members are well known and are widely used in walls or ceilings or roofs of buildings, inter alia.
  • a locking mechanism arranged at one or both edge of the sash of a window or other aperture closure member is often used to prevent the sash from being opened unintentionally.
  • a movable locking member such as a pawl, a ratchet or the like, for cooperating with a striker plate, said striker plate having a recess, slot or the like for cooperating with the locking member in a locking position.
  • the locking member may often feature means for locking the locking member in relation to the striker plate, and said means, which may be a boss or an indentation, may have been designed to engage with a part of the striker plate.
  • Still further locking assemblies have included such as in WO0406349 which involves a lock assembly, especially for locking a window, a door or the like, comprising a base member, an operating member pivotally connected to the base member, a link member pivotally connected to the base member, a latch pivotally connected to both the link member and the operating member, said operating member being provided with a pivotable elongated handle bar having a first side facing the operating member.
  • DK patent no. 168406 also discloses a lock assembly of the above type.
  • a still further pivotable elongated handle bar lock actuating device is disclosed in EP0792991 .
  • an object of the present invention to provide an openable closure member such as a door or window with improved ergonomic characteristics, particularly in alternately opening and then securing them in closed position.
  • One or more of these objects may be achieved in accordance with the assembly of claim 1 of the method of claim 16 by providing a window or other openable aperture closure member with a magnetic securing means and a method of operation thereof.
  • a securing means eases the closing and securing process and/or contrarily simplifies the opening process.
  • Such a magnetic means may be made useful by a magnet which is cooperative with a magnetically attractive part (a part with a high magnetic permeability or another magnet) to alternately securely hold and release an openable part within a stationary frame, as for example, a pivotable window sash in a stationary window frame.
  • a magnetically attractive part a part with a high magnetic permeability or another magnet
  • the closure member is provided with compressible gasket.
  • the magnetic attracting force is larger than the gasket repulsion force, so that an positive effective closing force is created, and a user does not need to apply any substantial force to compress the gasket.
  • a locking means for locking the sash or door structure to the frame structure may also be included.
  • a leverage mechanism may be provided to overcome the effective closing force.
  • the present invention relates generally to securing devices or systems for an aperture closure member such as a window or a door (also car door), the primary securing systems hereof including a magnetic securing device or assembly.
  • a magnetic assembly may generally include a fixed magnetic field element, such as a permanent magnet or an anchor, and a movable magnetic field element, such as a permanent magnet or an anchor, which cooperate to alternately, first, engage and hold or secure the aperture closure member in closing position of said aperture, and second release and allow for opening of the closure member relative to the aperture.
  • the invention further relates to an overall combination of an aperture and aperture closure member, such as a window or a door, the aperture being defined by a substantially fixed frame and the aperture closure member being a movable means such as a movable sash, said combination further including a magnetic securing device or system for alternately securing and releasing the aperture closure member relative to the aperture, e.g. for opening and closing said aperture.
  • an aperture and aperture closure member such as a window or a door
  • the aperture closure member being defined by a substantially fixed frame and the aperture closure member being a movable means such as a movable sash
  • said combination further including a magnetic securing device or system for alternately securing and releasing the aperture closure member relative to the aperture, e.g. for opening and closing said aperture.
  • the combination or assembly of an aperture and an openable closure member therefor is generally identified with the reference numeral 10, the aperture being defined by a frame 12 and the closure member or window identified generally by the reference numeral 11.
  • the combination 10 may be, as shown in the drawings according to a preferred embodiment of the invention, an openable window assembly 11 with a main, substantially stationary, or fixed frame structure 12 which includes a top member 5, a bottom member 6, and side members 7 and 8, and an openable sash structure 13 with a top member 1, a bottom member 2, and side members 3 and 4.
  • the sash structure 13 carries a window pane 15 which together form the openable closure member 11 in the embodiments shown in the drawings.
  • the sash structure 13 is pivotally journalled in the frame structure 12 with an axis of rotation which as shown, may be parallel with the top and bottom members and may be top or bottom hung or established substantially halfway (or at any other disposition) between them by means of the pivotal fittings 9.
  • the rotatable sash 13 may be alternatively (or even alternately; see Fig. 4 described below) journalled about alternate fittings 9 at or about the top or bottom members, or alternatively (or alternately) at a position at or about and/or parallel to the side members.
  • FIGs. 3 and 4 schematic side views of the window assembly 10 as a combined turn/pivot window are shown, in which the sash structure 13 and the window/closure member 11 under normal use may be either top-hung or substantially centrally pivotal relative to the frame structure 12, or alternately both.
  • both pivotal positions are shown in dashed lines in Fig. 4, with the central alternative shown in a solid line in Fig. 3.
  • the window/closure member 11 may function as a pivot window which is manually openable and closable through use of a handle member here shown, Fig. 4, represented by handle 35 on the interior side of the sash bottom member.
  • the handle 35 may be top or bottom or otherwise situated.
  • the sash structure 13 may be pivotally connected with intermediate hinge members 9 often positioned substantially centrally between the upper and lower parts of the sash and frame side members 3, 4 and 7, 8, respectively.
  • intermediate hinge members 9 often positioned substantially centrally between the upper and lower parts of the sash and frame side members 3, 4 and 7, 8, respectively.
  • the top-hung or centrally-disposed hinges may be used (as alternatively could bottom disposed hinges or hinges disposed in the respective top and bottom members 1, 2 and 5, 6).
  • the axis of rotation of the substantially central swingable connection lies approximately halfway between the top and bottom members in the same manner as shown in Figs. 3 and 4, and operation of the window to this pivot or swing movement is carried out in a manner frequently used in connection with roof windows, inter alia.
  • the handle assembly 35 may be disposed in a substantially horizontal disposition, i.e., operably parallel to the top and/or bottom members 1, 2 and 5, 6 of the sash and frame, and may be disposed at or adjacent the top members 1, 5 (not shown), or may be disposed at or about or adjacent the bottom members 2, 6 as shown in Figs. 3 and 4.
  • the handle bar assembly 35 could be disposed at various dispositions top to bottom horizontally, or the handle bar member 35, or the like could be disposed in a lengthwise position parallel with the side members 3, 4 and 7, 8, and adjacent one or the other sides 3, 7 or 4, 8. Even so, it should be noted that these alternatives may have a variety of functional distinctions or restrictions not required or impacted by the preferred top and/or bottom horizontal dispositions shown and initially described here.
  • the handlebar assembly 35 may act not only as a maneuvering device for the movable sash 13, i.e., alternately into open and closed positions but also as an actuator for alternately engaging and disengaging the locking/securing device.
  • Unshown alternatives could provide for the handlebar assembly to be connected to the frame 12 for actuating the locking/securing device, but would likely lose functionality for maneuvering the sash and aperture closure 11 open and closed.
  • a first feature of a push/pull member 35 is in a first preferred interaction thereof with one or more locking or securing devices or assemblies hereafter referred to generally using the reference numeral 20. Details of such alternative locking or securing devices or assemblies 20 will be addressed below; but first; more description of a preferred push/pull handle bar assembly 35 will be described with particular reference to Figs. 5-10, inter alia.
  • Each assembly may be a magnetic securing device/assembly 20 including a magnetic unit 50 and a cooperating magnetic unit 54 to be affixed (as by screws, nails, embedding or other means) to a corresponding fixed frame member, e.g., either top or bottom frame member 5 or 6.
  • the fixture may have, for example, a magnetic unit 50 including a super magnet in the form of a bar magnet 51 made from or at least including Neodymium-Iron-Boron (Nd 2 Fe 14 B) .
  • the bar magnet 51 is disposed on a substantially L-shaped member 52 of a magnetically permeable material such as iron to effectively form a U-shaped magnetic unit with both poles facing in the same direction.
  • the magnetic device 20 includes similar or magnetic unit 54 with a super magnets in the form of a bar magnet to 55 disposed on a substantially L-shaped member 56 of a magnetically permeable material.
  • the two magnetic units are arranged such that opposite poles face one another.
  • the magnetic units 50,54 are embedded in plastic (not shown), preferably in a layer of plastic or similar suitable material that is a few millimeters thick. Thus, in the closed position the one another facing surfaces of the two magnetic units 50,54 are separated by a layer of plastic, i.e. a medium with a low magnetic permeability.
  • An eyelet 43 or other hook receiving portion is disposed connected to the frame fixture 41 (or may otherwise be connected to the window frame) for receiving a securing hook 44, or the like, also described below.
  • the eyelet 43 is provided wit a roller 61 that cooperates with a cam 48 that will be described in greater detail below.
  • the magnetic units or portions 50,54 overcome the repulsion force of the gasket and secure the aperture closure member 11 in closing position of said aperture.
  • the closure member In operation, starting from an open position, the closure member is manually moved towards the closing position. When closure member abuts with the gasket, the attractive force between the magnetic units 50,54 (cf. Fig. 10) is larger that the repulsive force of the gasket under compression and the last part of the closing movement of the closure member is automatic or at least requires very little effort.
  • the closure member 11 In the closed position the closure member 11 is, in this embodiment, secured, but not locked, e.g. if the closure member is a window or a door of a car, a house or other building to prevent a burglar from opening the closure.
  • the assembly is configured such that the effective closing force (magnetic attractive force minus the gasket repulsion force) is relatively small, preferably only large enough so as to ensure that variations caused by production tolerances do not lead to a negative effective closing force.
  • the effort required to move the closure member 11 from the closed position to an open position is as low as possible.
  • the magnetic force of the magnetic device 20 may be such as to strongly resist opening, thus locking the sash against the frame, or may in be of limited strength (depending upon available materials, for example) and thus provide more relative securing of the sash against the frame.
  • An auxiliary or alternative locking device, e.g., a hookpiece 44, may then be used as described below.
  • the mere push and pull activation by manual maneuvering of the handle 35 to put the magnetic units 50,54 in position adjacent one another may provide greater simplicity in operation and actuation of the alternate securing/locking and then unsecuring/unlocking feature, simplifying the overall maneuvering necessary by the human operator to both engage and disengage, and/or improving the overall ergonomics of the opening and/or closing of the closure member 11 relative to the aperture.
  • the positive effective securing locking force is quite substantial, if not enough to lock the sash to the frame for burglary prevention.
  • a leverage mechanism actuated by the handle bar 35 and including one or more cams 48 assists in overcoming the effective securing force (Fig. 10) when the closure member is to be moved from the closed position to an open position.
  • the preferably elongated handle bar 35 which has one or more, here two, connecting bars 37 which operably connect the bar to the cams 48.
  • Such mechanical parts include generally as shown in Figs. 5-9, one or more, here two, gear assemblies 38, which are mechanically connected to an elongated rotational rod 39.
  • the gear assemblies include a rack 65 attached to the connecting bar 37 and a pinion 66 mounted on the elongated rod 39.
  • These parts, particularly the gears 38 may then be connected (as by nails or screws or other connection means) to the sash, see e.g., elongated horizontal sash member 1a or 2a (which could be a part of or comprise the entirety of the sash upper or lower member 1 or 2, see descriptions thereof above).
  • the connecting bars 37 are disposed to move translationally back and forth within (e.g., telescopically in and out of) the gear assemblies 38 (see the arrowheads in Figs. 5) with alternate pushing and pulling forces applied to the bar 35.
  • the rotational rod 39 may be disposed in rotational capacity within a receiving trough or other channel like feature (not shown) defined in the sash member 1a or 2a.
  • the cams 48 are mounted onto of a elongate shaft 39 (at or near the opposite ends thereof) and rotate in unison therewith. In the closed position (Fig. 7) the cam 48 abuts with the roller 61 at the lowest point of the cam profile. This part of the cams 48 is also provided with a latch or hookpiece 44. In the closed position the latch or hookpiece 44 engages the eyelet 43, thereby effectively locking the closure member to the frame.
  • an auxiliary locking device may be used, e.g., for redundancy or to provide actual locking if the magnetic member 20 is not sufficiently strong to lock (e.g., rather than merely secure) the aperture closure member in closed position by itself.
  • the magnetic securing device 20 may be used with an auxiliary locking device, particularly a latch or hookpiece 44, thereby providing a secure stay device plus a lock device.
  • the auxiliary locking member or mechanism, 44 can thus be an integral part of the cam 48, although it would also be possible to provide attach one or more separate arms or hooks to the elongated shaft (not shown), i.e.
  • latch 44 may be operated by conventional means so long as it is adapted to extend into a recess or eyelet 43 connected to or within the frame 12 as for example in either upper or lower member 5 or 6 (or in the respective side member 7 or 8) to secure the sash against undesired opening.
  • the latch 44 is preferably not loaded at any time by the force caused by the compressed gasket).
  • the magnetic lock first overcomes the pressure of the gasket and thereafter, if used, the hookpiece 44 may be used to catch the eyelet 43 when the sash is secured in closed position by the magnet.
  • the order is reversed, so that the latch 44 may be disengaged from the eyelet 43 whilst the magnetic securing means still withstands the opening force exerted by the gasket onto the sash.
  • the effective closing force is then overcome after the latch has disengaged the eyelet.
  • the profile of the cam 48 assures that there is a substantial leverage effect on the (pulling) force that the user applies to the handle bar 35.
  • Fig. 8 shows the assembly in a semi-open position where the cam is acting on the roll 61 to overcome the last part of the effective closing force
  • Fig. 9 shows the assembly in an open position in which there is no longer any effective closing force.
  • FIG. 10 A graphical representation of an embodiment of an operable magnetic force versus a gasket force is set forth in Fig. 10.
  • a gasket force line L is shown graphically as a dashed line, while the magnetic force line is shown in solid line form.
  • On the abscissa is the Aperture Opening Distance starting at the left side at A which represents closure of the aperture at zero distance (i.e., substantially zero distance between the sash and the frame) extending to a point B which is where the gasket force drops to zero representing an open aperture condition (i.e., where the gasket is removed from contact with sash.
  • On the ordinate is the measure of force.
  • Point U represents the maximum closure-resistive force of the gasket, which may be empirically determined and point V represents the amount of closure force of the magnet.
  • the magnet 20 will be chosen to have a closure force at least equal but preferably slightly greater than the gasket force (otherwise, the gasket will successfully open the aperture against a lesser magnetic force).
  • the resulting effective closing force is represented by the dotted line, and the effective window closing force is represented by point W.
  • the magnetic force is chosen to be greater than the gasket force in all positions of the sash; however, it may be determined that this may not always be so.
  • another force typically manual, would need to be applied to overcome the gasket force at least until the magnetic force becomes larger than the gasket force. Then, the magnetic force will be sufficient to hold the window in closed position.
  • the window construction of the primary embodiments is a pivot window for installation in an inclined roof
  • the window or other aperture closure member may be installed in any of various orientations in/on a building, a vehicle or other situs for closing a respective aperture.
  • a particular application of the assembly for securing is in doors for automobiles buses and lorries, which are typically provided with a resilient gasket that requires a substantial force to be compressed.
  • the typical "slamming shut" of these type of doors can be avoided without the use of solenoids or electromotors as known from the prior art.
  • the top, bottom and side members of the frame and sash structures may for the major part be built using wood products, although it is also possible to use metal or plastic.
  • These profiles, particularly those which may be exposed to the weather may also be covered with covering members which are constituted of comparatively thin metal sheet profiles, for instance of aluminum, and which together may provide a completely weather-shielding enclosure of the window.
  • the hinge(s) 9 and the operable securing/locking means 20 and/or 44 may be made from metallic material, such as steel, or strong plastic materials, such as fiber reinforced plastics or combinations thereof, the primary exceptions being the magnetic and/or magnetically activatable members which may be of magnetic materials.
  • the handle bar assembly 35 may additionally and/or alternatively be made from various combinations of materials including, without limitation, wood, metals and/or plastics.
