Definitions

  • the invention relates to a safety limiter for a frame element, and an installation tool for the safety limiter.
  • Safety glass which is heavier than conventional window glass, is increasingly used in window panes. For holding and stopping a window equipped with safety glass, great forces are required, causing a strain on the hinges and fittings of the window. If the movement of the window is not limited, it can move freely and stop first upon an impact on a solid object, such as a floor, a wall, an adjacent window, or another object.
  • DE 20 2007 017 364 U1 describes a device for holding a window in a tilted position.
  • One part of the device namely a casement part
  • another part namely a frame part
  • a cord connects the casement to the frame and extends through the frame part.
  • the movement of the window casement is limited by means of a weight suspended from the frame part, preventing the cord from passing through the frame part.
  • EP 0231849A describes a security device for preventing unauthorized opening of doors.
  • the device comprises two mounting means connected by a cable. At its ends, the cable is provided with means preventing the passage of the cable through holes in the mounting means.
  • CN 106002796A describes an installation tool for installing cabled connectors.
  • the installation tool comprises a protrusion whose tip is provided with a hexagonal clamping groove, whereby the installation tool can be applied to engage a hexagonal nut at the lower end of a connector, located below the installation plane.
  • the handle of the installation tool is on the rotation axis when the tool is applied.
  • a safety limiter makes it possible to limit the movement of a cover element, fastened by hinges to a frame element installed in an opening of a building, with respect to the opening.
  • the cover element is fastened by hinges to be movable between a closed position and an open position. In the closed position of the cover element, the opening of the building is covered by the cover element, whereby the cover element prevents access through the opening. In the open position of the cover element, the opening of the building is at least partly open, whereby it is possible to enter and/or to exit the building through the opening.
  • the safety limiter limits the movement of the cover element and thereby the size of the opening in the open position of the cover element.
  • the frame element may be made of, for example, wood or metal.
  • cover elements include at least doors, windows and hatches.
  • a building may comprise one or more openings, such as door openings and window openings, in which doors, windows and hatches can be installed, respectively.
  • the cover element may be installed in a frame element, such as a frame, arranged in the opening of the building.
  • the cover element may be fitted to the shape and the size of the opening in the building.
  • the cover element may comprise, in turn, a sash or casement element, such as a casement, for example a door casement or a window casement.
  • a pull transmitting means may be, for example, an elongated piece, such as a strip of material, a rope, a cable, or a cord.
  • the pull transmitting means may be made of, for example, plastic, metal, or fibre material. Examples of fibre material comprise natural fibres, such as acaba, sisal and hemp, as well as synthetic fibres, such as nylon, polypropylene and polyester.
  • the pull transmitting means may comprise an elongated middle section and opposite ends separated by the middle section in the longitudinal direction of the pull transmitting means. One of the opposite ends comprises a bulge, and one of the opposite ends is an angle fitting.
  • the pull transmitting means has a tensile strength making the pull transmitting means sufficiently strong to receive the weight, i.e. the pull or tensile force, of the cover element, such as a window, a door or a hatch, and to support the cover element directly or e.g. via the frame to the building.
  • the pull transmitting means is preferably rigid. Thanks to its rigidity, the pull transmitting means can resist bending in a direction transverse to the longitudinal direction of the pull transmitting means.
  • the pull transmitting means may have various profiles, i.e. shapes in the cross-section transverse to the longitudinal direction.
  • a circular profile provides the pull transmitting means with uniform stiffness.
  • the material strip has a flat profile in its cross-section transverse to the longitudinal direction. The thickness of the strip is much smaller than its width, whereby the width dimension and the height dimension, or the thickness, are significantly different from each other. Thus, the rigidity of the strip in the width direction of the profile may almost negligible, while the strip can be bent in the thickness direction of the profile.
  • the safety limiter and the installation tool according to the invention can be implemented in a number of ways, of which some examples will be described in the following.
  • a safety limiter 100 and an installation tool 200 for the safety limiter are provided.
  • the safety limiter is suitable for use in arrangements comprising a frame and a casement fastened to the frame by means of one or more hinges, for example, to be movable from an open position to a closed position and from the closed position to the open position.
  • casements comprise a window casement and a door casement which may be fastened to a window frame and a door frame, respectively. Moving the casement with respect to the frame makes it possible to close or to open an opening delimited by the frame, such as a window opening or a door opening, at least partly or even totally.
  • the safety limiter 100 comprises a sleeve 102 which can be inserted in a hole 106 in the window frame 104, the mouth 108 of the opening being arranged on the outer surface of the window frame 104 facing the window casement 110, and the opening 106 extending from the mouth 108 into the window frame in the depth direction 112 of the window frame 104.
  • the safety limiter comprises a cable 114 comprising a first end with a bulge 116 for limiting the movement of the cable 114 through the sleeve 102, and a second end with a angle fitting 122.
  • the safety limiter further comprises a fitting 126 comprising a front edge 132, and the fitting 126 comprises a hole 128, the hole 128 in the fitting 126 extending substantially in the direction 111 of the outer surface of the window casement 110.
  • the angle fitting 122 and the hole 128 are fitted to each other, whereby at least part of the angle fitting 122 can be received in the hole 128 in order to limit the movement of the window casement 110 from the window frame 104 to a distance at which the cable 114 is pulled through the sleeve and fastened by the angle fitting 122 to the fitting 126, and the bulge 116 is supported to the sleeve, whereby the weight of the window casement 110 can be supported to the window frame 104 via the cable 114.
  • the safety limiter is used for fastening the window casement to the window frame, whereby the opening of the window casement is limited by the length of the cable.
  • the safety limiter limits the movement of the window casement in relation to the window frame
  • the greatest distance between the window casement and the window frame is achieved when the window casement pulls the cable out of the sleeve so that the bulge of the cable is trapped by the sleeve within the window frame and prevents the movement of the window casement further away from the window frame.
  • the window casement can be released to be opened without the safety limiter limiting the movement of the window casement, by pulling the angle fitting out of the hole 128 in the fitting 126. In this way, the window casement can be opened as desired, for example for washing the window.
  • the pull of the cable 114 is guided by the angle fitting to extend in parallel with the outer surface of the window casement, and by the bulge into the window frame.
  • the safety limiter supports the window casement in its extreme position, in which the distance between the window casement and the window frame is the greatest when the safety limiter is used.
  • the bulge 116 of the cable 114 supports the cable within the sleeve, whereby the sleeve prevents the cable from passing through the sleeve, and the pull of the cable is transmitted to the sleeve and further via the sleeve to the inside of the window frame.
  • the fitting of the safety limiter comprises a guide element 120 which is configured to position the fitting 126 on the outer surface of the window casement 110 so that the front edge 132 of the fitting 126 is flush with or extends beyond the outer edge 118 of the window casement 110.
  • the placement of the fitting makes it possible to insert the free end of the angle fitting in the hole in the fitting so that a contact between the angle fitting and the window frame can be avoided.
  • the guide element 120 of the fitting 126 may be an extension of the front edge 132 of the fitting 126, which can be supported to the outer edge 118 of the window casement 110 after the fitting has been installed in the window casement 110.
  • the guide element covers the outer edge 118 at least partly, whereby the guide element can protect the outer edge 118 of the window casement 110 from a contact with the angle fitting.
  • Figure 1 shows a window frame 104 installed in a window opening of a building, such as a house.
  • the window frame is a peripheral structure in which a window casement 110 can be fastened by one or more hinges.
  • the window casement 110 and the window frame 104 can be fitted to each other so that the window casement closes the window opening when the window casement is in the closed position.
  • the window casement 110 In the closed position, the window casement 110 is substantially secured against the window frame 104, and there is typically no opening, or at least no need for an opening, between the window casement and the window frame.
  • the cable is inserted in the hole 106 inside the window frame 104.
  • the window casement is turned or tilted, supported by the hinges, with respect to the window frame, for example away, i.e. outwards, from the window frame.
  • the window casement pulls the cable through the sleeve, and the window casement can be moved away from the window frame until the bulge in the cable supports the window casement to the sleeve, which prevents movement of the window casement.
  • the window casement 110 is a casing structure in which a window pane is fastened.
  • the window pane may be made of e.g. glass, such as safety glass, which is at least partly transparent to light.
  • Safety glass is glass having a very strong structure which makes it safe.
  • Safety glass may be tempered, laminated and/or wired glass.
  • the thickness of the safety glass may be, for example, 4 mm for tempered and/or laminated glass.
  • the use of safety glass is recommended, for example, for a fixed window at a height lower than 700 mm from the floor. In practice, safety glass can be used to avoid accidents, such as falls, and/or to protect from violence from the outside.
  • the window casement 110 can be fastened with one or more hinges to the window frame 104, whereby the window casement can be turned from the open position to the closed position, and vice versa.
  • Fig. 1 shows the window casement of a bottom-hinged window in the open position. In the open position, in the closed position, and when turning the window casement between these positions, the window casement remains connected to the window frame.
  • the window casement can be opened from the closed position by moving, i.e. turning, the upper edge of the window casement apart from the window frame in the depth direction of the window frame. In this way, the window casement is brought to the open position.
  • the upper edge of the window casement moves along a curved path away from the window frame.
  • the window casement may be arranged in a side-hinged window, whereby a vertical edge of the window casement is fastened with one or more hinges to the window frame, and the window casement can be opened from the closed position to the open position by moving the vertical edge opposite to the hinged vertical edge of the window casement apart from the window frame in the depth direction of the window frame.
  • the vertical edge of the window frame is supported by the hinges when it moves along a curved path away from the window frame.
  • the sleeve 102 is an elongate piece which is hollow inside, whereby the cable 114 can be inserted into and through the sleeve.
  • the inner diameter of the sleeve may thus be greater than the thickness of the cable.
  • the cable can be moved in the longitudinal direction of the sleeve.
  • the outer surface of the sleeve is provided with a threading 107, by which the sleeve can be fastened to the window frame 104 by driving the sleeve into the window frame in the depth direction 112 of the window frame.
  • the window frame may be made of, for example, wood, whereby the threading of the sleeve can bite into the wood of the window frame and thereby fix the sleeve in the hole 106 in the window frame.
  • the window frame may be provided with an integrated counterpiece with a threading matching with the threading of the sleeve.
  • the sleeve 102 may comprise a front disc 103 with a hole 105 for moving the cable into the sleeve, into the window frame, and out of the sleeve, to the outside of the window frame.
  • the inner diameter d s of the sleeve may be greater than the diameter d e of the hole in the front disc, whereby the sleeve and the window frame can be covered under the front disc, and the hole in the front disc guides and/or supports the cable at the mouth of the sleeve.
  • the hole in the front disc may be aligned with the axis of the sleeve, whereby the cable passing through the hole in the front disc is guided to the axis of the sleeve, spaced from the inner walls of the sleeve. In this way, it is possible to reduce contact between the cable and the inner face of the sleeve and thereby friction on the cable caused by the inner face.
  • the installation of the sleeve in the window frame is provided with a finished appearance.
  • the sleeve can be installed by placing the front disc on the outer surface of the window frame so that the cable inserted in the sleeve protrudes from the front disc.
  • the front disc may act as a cover plate on the opening 108 of the hole in the window frame, whereby the front disc covers, for example, the boundary between the sleeve and the window frame on the surface of the window frame around the sleeve.
  • the outer face of the sleeve 102 is provided with a threading 107
  • the front disc 103 comprises one or more holes, openings, incisions, or grooves for screwing and fastening the sleeve with the threading 107 into the window frame.
  • the holes, openings, incisions, or grooves in the front disc make it possible for an installation tool 200 to engage the front disc for rotating and screwing the sleeve into the window frame.
  • the hole in the window frame may be longer than the sleeve in the depth direction of the window frame.
  • the sleeve may consist of, for example, steel.
  • the cable 114 is an elongate piece comprising a flexible middle section extending between the opposite ends. At one end, the cable is provided with a bulge 116, and at the other end, the cable is provided with a angle fitting 122. The cable is fastened by the bulge via the sleeve 102 to the window frame 104 and by the angle fitting via the fitting 126 to the window casement 110.
  • the bulge 116, or expansion may be spherical or have the shape of a sleeve, in which the cable is arranged.
  • the bulge can be attached to the cable by crimping the bulge onto the cable, or by soldering the bulge onto the cable.
  • the bulge may consist of, for example, lead.
  • the size of the bulge may be selected so that the bulge can move within the window frame in the depth direction of the window frame 104, but not through the sleeve.
  • the diameter of the spherical bulge is smaller than the hole in the window frame, in which the sleeve is installed in the window frame.
  • the inner diameter of the sleeve 102 may be fitted so that the bulge cannot pass through the sleeve; in other words, the sleeve may have an inner diameter smaller than the bulge.
  • the angle fitting 122 comprises a first section which fastens the angle fitting to the cable and extends as an elongation from the cable, and a second section arranged at an angle to the first section.
  • the first section of the angle fitting may be attached to the cable by soldering or crimping.
  • the second section of the angle fitting is free; in other words, it is the free end 140 of the angle fitting.
  • the free end may be introduced in a hole 128 in the fitting 126, whereby the safety limiter can restrict the movement of the window casement 110, and the weight of the window casement can be supported via the cable to the window frame 104.
  • the angle between the sections of the angle fitting may be, for example, 80 to 100 degrees, such as 85 to 95 degrees, for example 90 degrees.
  • the pull of the cable can be guided to be parallel with the outer surface of the window casement.
  • the flexibility of the cable makes it possible for the cable to bend in a direction transverse to the depth direction of the window frame. Thanks to the flexible section of the cable extending from the angle fitting to the opening 105 of the sleeve and into the window frame, the longitudinal direction 113 of the angle fitting towards the window frame does not need to extend from the fitting directly towards the hole 105 in the sleeve.
  • the window casement When the window casement is moved from the closed position to the open position, the window casement pulls the cable fastened to the fitting out of the window frame and, finally, the bulge of the cable is supported to the sleeve and limits the distance between the window casement and the window frame to the open position. Bending of the cable allows the window casement to turn with the hinges when the window casement is moved from the closed position to the open position and the window casement pulls the cable out of the window frame.
  • the bulge and the angle fitting may be made in the form of solid pieces of stainless steel, and the cable connecting them may be a steel braid, i.e. a braided steel cable.
  • the braided steel cable may be coated with plastic.

  • the fitting comprises a locking mechanism 134 arranged to engage a locking formation 124 for keeping the angle fitting 122 in the hole 128 of the fitting 126.
  • a force can be exerted on the part of the angle fitting received in the hole 128 of the fitting 126, for example on the locking formation 124 at the free end 140 of the angle fitting, to hold the angle fitting in the hole.
  • the pull of the cable is exerted on the outer surface of the window casement.
  • the locking mechanism may be, for example, a spring press screw.
  • the locking formation 124 may be, for example, a groove or an incision in the angle fitting.
  • the locking mechanism 134 may be configured to be locked in the angle fitting 122 via the locking formation 124 after the locking formation 124 has been received at a locking depth in the hole 128 in the direction 111 of the outer surface of the window casement 110.
  • the locking mechanism may comprise a spring 136 and a latch element 138.
  • the spring presses the latch element against the locking formation of the angle fitting.
  • the free end 140 of the angle fitting may be designed in a round or slanted shape. The design of the free end is useful in deflecting the latch element against the spring force of the locking mechanism, facilitating the insertion of the angle fitting into the hole in the fitting.
