Definitions

  • the invention concerns a roof or façade structure tilt member opening stop, limiting the opening of the tilt member with a horizontal or near horizontal axis of rotation, for instance of a pivot window sash or a roof hatch flap.
  • the stop arrangement is a flat kinematic system, perpendicular to the axis of rotation of the tilt member. Its operation is based on the scissor-like folding of two advantageously flat connecting members, joint together in a pivoting or pivoting-sliding manner, during the closing movement, and unfolding during the opening movement. Both connecting members are simultaneously secured to the opposite ends also in a pivoting manner - one to the fixed frame structure, e.g. a window frame, the other one to the tilt member profile.
  • any non-plumb axis of rotation of the tilt member causes a torque dependent on the position of the centre of mass against the axis of rotation. If the centre of mass of the tilt member is located above the axis, the torque acts towards its opening. In this case, known solutions, described in the prior art section, perform their function well. However, if the centre of mass of the tilt member is located below the axis, the torque acts towards its closing and the stop should have its structure rigid enough to ensure the tilt element is held in the open position.
  • a solution of the opening stop consisting of two rods connected together like scissors is known from DE 42 25 328 .
  • One of the rods is secured in a pivoting-sliding manner with one end to the window sash frame, while the other one is movably connected to the fixed window frame and fitted at its end with a profiled hook.
  • both rods unfold like scissors until they are set in the maximum position limited with elastically overlapping projections, situated at the ends of both rods.
  • the rods overcome the friction force occurring between the projections and at the same time one rod moves with its socket on a mandrel mounted on the window fixed frame and the other one moves with its mandrel in a socket situated in the window sash frame until the window has been fully closed.
  • WO 9631676 a solution to be used as an opening and closing stop, in particular of a façade window.
  • the device consists of two arms connected together like scissors.
  • the first stop arm at one end is connected pivotably to an assembly plate.
  • the other arm, connected pivotably to the first one is secured with its other end to the window frame.
  • the opening is basically interlocked at the point of the biggest arm spacing against each other.
  • a possibility of any setting (interlocking) of the arms against each other was applied, with the use of a spring-ball arrangement.
  • this solution largely complicates the stop design.
  • the stop design is based on two connecting members joint together, and respectively to the fixed frame and to the tilt member, pivotably.
  • the operation of the scissor-like opening stop is based on the possibility of free turn of the connecting members against each other, from the initial condition, only in one direction.
  • the initial condition of the arrangement determined by the dead centre, means the connecting members are in the unfolded position parallel to each other.
  • the mutual rotation of the connecting members in the opposite direction is restricted by a simple interlocking member. Most often it is an additional mandrel or bent projection belonging to one of the connecting members.
  • the location of the interlocking member defines the maximum angle of deflection of the connecting members against each other.
  • a solution like this has two functions - limiting the maximum opening of the tilt member and supporting it in the open position. Manual operation of opening of the tilt member and its interlocking in this position is limited to full opening of the tilt member, and subsequently initiating the mutual turn of the connecting members in the interlocking direction. However, a position like this is little stable and depends on the continuous effect of force caused by the tilt member. In addition, even accidental catch of the arrangement may cause the connecting members to go over the dead centre and the tilt member to close completely in an uncontrolled manner.
  • the objective of the proposed solution is to introduce a scissor-like opening stop, whose design ensures the tilt member automatically interlocks and remains in the open position, in particular in the case of the torque acting on the tilt member in the closing direction.
  • the opening stop design should ensure the turn of the tilt member can be easily unlocked when closing, and it is protected against uncontrolled unlocking.
  • the essence of the invention is the rotation stop mechanism design supporting mechanically the rotation of the connecting members against each other in the interlocking direction. It occurs during the closing movement of the tilt member from the maximum open position, where the connecting members are parallel to each other.
  • the arrangement can also be unlocked by re-opening of the tilt member to its maximum position, and next simultaneous closing of the sash and manual initiation of the mutual rotation of the connecting members of the arrangement in the direction opposite to the interlocking direction.
  • the opening stop is a flat kinematic system comprising two rigid connecting members connected together in a pivoting-sliding manner on a pivot mating a yoke guide.
  • the other node of each connecting member is pivotably connected respectively to the fixed frame or to the tilt member.
  • a system like this has two degrees of freedom.
  • the yoke guide situated in the first connecting member, mating the pivot mounted on the other connecting member, forming together a pivoting-sliding kinematic couple, has its longitudinal axis situated angularly, at the ⁇ angle against the longitudinal axis of its connecting member.
  • the rotation stop has a lock, comprising a socket made on the extension of one of the connecting members, advantageously the member with the yoke guide and a mandrel mounted at the other connecting member.
  • the mandrel is placed between the connecting member nodes, e.i. between the pivot and the point of securing to the fixed frame or the tilt member, at a distance corresponding to the distance between the socket and the yoke guide in the other connecting member.
  • the mandrel has its axis advantageously parallel to the pivot axis.
  • the socket performs two functions - with the bearing surface it restricts the maximum angle between the connecting members in the interlocking direction of the rotation stop and it interlocks the mutual rotation of the connecting members against each other in this position.
  • the first connecting member has at its free end the bearing surface restricting the mandrel movement in the direction interlocking the turn.
  • the geometrical centre of the socket does not coincide with the axis of its connecting member.
  • the axis of the first connecting member is not parallel to the axis of the other one.
  • the scissor-like turn stop When the tilt member is closed, the scissor-like turn stop is folded, in addition the angle between the connecting members in this condition can have any value, depending on the designed opening angle of the tilt member and design parameters of the stop itself. While opening the tilt member, the angle between the connecting members increases until it reaches the straight angle at the maximum opening of the tilt member. In this position the stop interlocks any further turn of the tilt member, acting like a tension member holding the tilt member when the torque is acting towards its opening.
  • the turn stop performs also a supporting function, i.e. interlocking the closing when the torque acts towards its closing, then the tilt member is automatically interlocked after the return travel has been initiated.
  • the turn stop connecting members are in the obtuse position parallel to each other, the pivot is located in the end part of the yoke guide, and the mandrel is extended from the socket. In this position the mutual turn of the connecting members is possible in one direction, not interlocking, by any angle (even up to 180°) resulting from the design specificity, and the tilt member may be freely closed.
  • the connecting members should be positively pushed together by applying a force to one of their outer nodes.
  • the reaction will occur at the other node. Due to the rotary nature of these nodes, the direction of forces is always parallel to the axis of the connecting members.
  • the torque resulting from the gravity force with its value depending on the angle of arrangement of the stop against the plumb-line has an effect on the connecting members. This torque has the highest value for the horizontal arrangement, whereas for the ideal vertical arrangement it is equal to zero.
  • the application of yoke guides enable the mandrel to be put into the socket and the relative turn of the connecting members to be interlocked. Because the pivot will move to the other end of the yoke guide, a rigid system will form, fully interlocking any mutual turn of the connecting members.
  • Fig. 1 shows the turn stop in the exploded view.
  • Fig. 3 shows the turn stop in the fully open position before interlocking, while Fig. 4 shows the turn stop in the interlocked position.
  • the turn stop 1, restricting and interlocking the rotary motion of the tilt member 2 against the fixed frame 3, consists of two rigid members made advantageously of a flat bar - connecting member 4 and connecting member 5 - joint together in a pivoting-sliding manner with a yoke coupling.
  • the first connecting member 4 has an hole at one end, which is used for pivoting connection to the fixed frame 3 or the tilt member 2, depending on the selected interlocking direction.
  • this connecting member 4 has a yoke guide 6 made angularly, at the ⁇ angle in relation to the axis of this connecting member 4, and the socket 7 made in the extension of this connecting member 4.
  • One of the edges of the socket 7 is extended and performs the function of the bearing surface 8.
  • the second connecting member 5 like the first one 4, at one end has a hole for pivoting connection to the fixed frame 3 or the tilt member 2.
  • the second connecting member 5 has a pivot 9 mating in a pivoting-sliding manner the guide yoke 6.
  • the mutual position of the pivot 9 and the yoke guide 6 defines the axis of rotation of the connecting members against each other.
  • a lock is used for complete interlocking of the common turn of the connecting members, comprising a socket 7 made in the first connecting member 4, and a mandrel 10 placed between the pivot 9 and the pivoting node of the second connecting member 5, that is the hole at its other end, at a distance matching the distance between the socket 8 and the yoke guide 6 in the first connecting member 4.
  • the design of the turn stop allows the connecting members to make a straight angle mutual turn around the axis of the pivot 9 in the non-interlocking direction. It means the connecting members from the fully open position, shown in Fig. 3 , may turn 180°, to the folded position, not shown in the drawings. However, in the opposite direction, the mutual rotation of the connecting members from the position acc. to Fig. 3 is restricted by the bearing surface 8, which limits the arcwise travel of the mandrel 10 around the axis of the pivot 9, whose relative position defines the maximum angle of deflection of the connecting members against each other.
  • Locking or interlocking of the turn of stop in both directions, occurs after the mutual pushing together of the connecting members has been forced, by applying a force to their outer pivoting nodes, which takes place while closing the tilt member 2.
  • the application of the yoke guide 6 enables the mandrel 10 to be put into the socket 7 and the relative turn of the connecting members to be fully interlocked.
  • the pivot 9 will move to the other end of the yoke guide 6, a rigid system will form, fully interlocking any mutual turn of the connecting members.
  • angular (angle a) arrangement of the axis of the yoke guide 6 against the axis of the first connecting member 4 causes, with the aid of even a small torque, resulting e.g. from the resultant gravity forces of the connecting members, automatic setting of the turn stop 1 in the interlocked position. It is unlocked after mutual parting of the connecting members.
  • Such a functionality of the turn stop 1 enables it to be safely used e.g. in pivot roof windows or roof hatch flaps, where the centre of mass of the tilt member 2 is below its axis of rotation, in other words the tilt member is opened upwards. In such a case interlocking of the tilt member in the open position is automatic, and its unlocking and possibility of closing occurs after its maximum deflection.
  • the turn stop 1 In this position of the tilt member 2, the turn stop 1 is in the fully open position, as shown in Fig. 3 . Unlocking of the turn stop 1 and enabling of the closing of the tilt member 2, only possible in this position of the turn stop, occurs after manual initiating of its turn in the direction opposite to the interlocking direction. The complete folding of the stop is possible due to the rib 11, which enables the mandrel 10 to be put into the vacated space without affecting the mechanical strength of the first connecting member 4.
