Definitions
- This invention relates to a ventilation window or door, in particular, a ventilation window or door having a hinged bidirectional pivoting system for tilting roof windows and doors that includes a ventilation flap actuating a lock.
- Inclined roof windows are adapted for inclined roofs, which can provide an abundance of sunshine for buildings and brighten interiors.
- a window in the prior art, for example, includes an inside window frame and an outside window sash structure, i.e., a pivotally mounted glass window structure, wherein the inside window frame is mounted on the wall or the roof, while one end of the outside window sash is pivotally connected with the inside window frame, and the other end can be opened or closed by a locking stay device.
- an outside window sash structure i.e., a pivotally mounted glass window structure
- a simple and elegant design includes that of a small door or window opening, i.e., a ventilation passage, interconnecting the interior and the exterior areas, combined with the door or window, which make it possible to open or close the ventilation opening embedded in doors or windows, so as to achieve an efficient exchange of air and ventilation between the interior and the exterior areas.
- references DE6903921 as well as EP0458725B1 show known structures and mechanisms for achieving air ventilation between exterior and interior areas and as well as present cover members which can pivot in a single direction designed to be connected with a window sash by a locking device.
- this cover member may pivot in a single direction so as to open or close the air passage, while driving a control member connected to a specially designed locking device, allowing the control member to be placed in various positions, such as three different positions.
- the pawls of the locking device are driven accordingly, so as to open or close the window at the same time the ventilation opening is opened or closed when the sash is closed.
- the cover member is positioned so that it blocks the air exchange direction between the interior and the exterior spaces, resulting in an undesirable air exchange effect and low efficiency.
- this design poses a natural and inherent defect. Since the ventilation cover member, i.e., the top ventilation member, connected with the lock system controls the opening of the air passage between the interior and the exterior areas, it is very likely that the window can be opened by acting on the ventilation cover member with a thin steel wire or other elements through the ventilation passage. This increases the possibility of unauthorized entries and penetration such as house burglaries and the like.
- the ventilation member additionally has a self-lock function, whereas in WO2002/08043 , this device should be activated manually.
- manual activation can be easily forgotten by a user, making it inconvenient to use, posing further dangers, and resulting in higher costs.
- the locking stay device contains a bar-shaped locking element which includes a cylindrical pin and a locking device, wherein the bar-shaped locking element is pivotally connected with the outside window sash, on which there are a plurality of position pawls, and the cylindrical pin is arranged on the inside window frame, which cooperates with the position pawls to adjust the opening of a vent, when closed, the inside window frame and the outside window sash are tightly connected by turning the locking stay device with a handle.
- the vent opening adjustment device is detached from the locking stay device which results in more parts, difficulty in assembling, higher manufacturing cost, and annoying operation.
- the bar- sharp locking element includes pawls which affect the mechanical strength of the locking element.
- the locking element is easy to slip from the cylindrical pin thereby affecting position and the use.
- locking devices have been proposed as well as such as one which includes a tilting sash on which is mounted an actuation assembly movable in translation and including a handle bar as well as a gear mechanism which converts a translation movement of an actuator element into a rotational movement of locking elements (EP 1746232B1 ).
- Such mechanism utilizes a magnetic means to actuate the locking elements, which may pose other inherent problems of long term usage and wear and tear.
- Other prior art propose similar mechanisms such as EP 1762679A1 , describing an assembly for securing a closure member in a closed position including the use of attractive magnets.
- locking devices in prior art typically use at least two hinged levers and two return springs as linking mechanism between the actuation slider and a latching hook.
- the disadvantages of this design include the number of components and complexity of the design mechanism.
- the new ventilation window may choose the direction of ventilation and whether to lock the window by bidirectional pivoting flap connected with the hinged arm.
- the pivoting flap may be positioned in various positions, for example, when in a closed position, the flap closes the ventilation passage while setting the locking mechanism in a locked position. In a first opened position, the flap is pivoted to open the ventilation passage while setting the locking mechanism in an unlocked position. In a second opened position, the flap is pivoted to open the ventilation passage while setting the locking mechanism in a locked position and the direction of the second opening position is opposite to that of the first opening position.
- the member mentioned above has disadvantages. Since different users apply pulling force of different direction to the flap, when actuating of the device, the they often pull two axis and two axis sleeves up and down at the same time. Especially in the case of fierce force applied by the user, the mechanism tends to occur bending deformation, the risk of detachment between the axis and the axis sleeve can be increased, mechanism malfunction and noises can occur, damage can be easy to occur to the members and service life can be reduced when operation. In order to reduce such phenomenon, the degree of adaptability between the end of the hinged arm and the circular arc shaped of the flap must be improved. This inevitably increases the requirements of the processing procedure and expensive processing cost.
- the technical problem that the present invention intends to solve is to provide a ventilation window or door having a locking device and a ventilation device, which combines a ventilation opening adjustment and locking mechanism that is simpler, low noise, lower requirements for processing procedure and higher reliability.
- it can also provide an operator with an auxiliary force to improve operability, while providing a supporting force to the ventilation window or door to reduce the risk of accidental failure, and when in the first opened position, the second opened position is simultaneously opened.
- the flap can provide automatic resilience force after releasing the handle and the flap can be in the first opened position, which avoids the risk of the failure of the mechanism when such a structure is pulled out.
- the present invention in one aspect, includes a ventilation window or door having a main frame, a glass-supporting sash that is arranged to tilt within the main frame, a ventilation passage provided in the sash, extending between an interior opening and an exterior opening of the window, with a locking device adapted to lock the sash to the main frame in a closed position, with the lock having a locking mechanism mounted on the sash inside the ventilation passage.
- the window or door has a pivoting flap mounted on the sash and connected to the locking mechanism, where the pivoting flap is adapted to pivot around a first axis which is stationary relative to the sash, between a closed position in which the flap closes the interior opening while setting the locking mechanism in a locked position and a first opened position in which the flap is pivoted to open the ventilation passage while setting the locking mechanism in an unlocked position.
- pivoting flap is adapted to pivot around a second axis which is stationary relative to the sash and parallel to the first axis, between the closed position of the flap and a second opened position in which the flap is pivoted to open the ventilation passage while keeping the locking mechanism in the locked position.
- the invention further comprises at least one articulation device, comprising a fixed block, the pivoting flap connected to the articulation device mounted on the sash by the fixed block, the articulation device further comprising:
- the elastic supporting device is preferably a torsional spring, one end of which is mounted on the connected arm, and the other end of which has a protrusion
- the fixed block further comprises a limiting slot located inside the fixed block to receive the protrusion.
- the first rigid connector and the second rigid connector face each other with a distance in order to avoid interference from occurring.
- a body of the first rigid connector and the second rigid connector has at least one through hole so that the first rigid connector and the second rigid connector are fixed on the fixed block and the pivoting flap by a bolt with a through hole or a threw.
- the first rigid connector may be divided into two separate parts, each of the two separate parts has at least one said through hole, wherein one of the separate parts is hinged to the first axis pin, and the other one of the separate parts is hinged to the second axis pin.
- the second rigid connector may be divided into two separate parts, each of the two separate parts has at least one said through hole, wherein one of the separate parts is hinged to the third axis pin, and the other one of the separate parts is hinged to the fourth axis pin.
- the third and the fourth axis are wound with torsional springs
- a supporting slot for supporting the torsional spring is arranged on the first and the second connected arms so that the flap tends to be kept in the closed position of closing the interior opening by resilience force of the torsional spring.
- the fixed block further comprises: at least one recess arranged in the limiting slot and applying frictional force to the elastic supporting device, and the recess applies frictional force to the elastic supporting device when one part of the elastic supporting device moves into the recess.
- the connector and each axis are always connected together during the movement process, which reduces the friction, wear and collision between the members. Especially, the noise can be reduced after the lubricating oil is applied, and the service life can be improved.
- the size of the members can be greatly reduced, the amount of materials used can be reduced in the production process, and the cost can be reduced.
- assembling space of the ventilation holes can be greatly reduced by the device for locking and ventilating windows or doors of the present invention via the hinge device, so that the size of the ventilation plate can be made narrower to increase the light passing area of the window.
- the articulation device allows the user to automatically obtain the resilience force from the elastic supporting device when the user opens the articulation device around the second axis through the elastic supporting device, thereby providing the user with an auxiliary force.
- the resilience force of the elastic supporting device can be balanced and stabilized in the opened state, further preventing the risk of accidental failure.

- the elastic supporting device 56 can achieve force balance under the action of its own resilience force and frictional force, and is supported at this position.
- the third and fourth axis pins are wound with torsional springs 84, 85, one end of which is supported in the supporting slots 92, 93 of the fixed block 17, and the other end of which is supported in the supporting slots 90, 91 of the first and second connected arms and can be deformed as the first or second connected arm rotates to obtain the resilience force.
- the elastic supporting device 56 is also a torsional spring, and its diameter is smaller than the torsional springs 84, 85 on the first and second axis pins.
- the torsional springs 84, 85 have a diameter of 1.2 to 1.6 mm.
- the torsional spring as the elastic supporting device 56 has a diameter of 1.0 to 1.4 mm; most preferably, the torsional springs 84, 85 have a diameter of 1.4 mm and the torsional spring as the elastic supporting device 56 has a diameter of 1.2 mm.
- both ends of the torsional springs 84, 85 on the third and fourth axis pins are respectively supported by the supporting slots in the fixed block 17 and the supporting slots on the first and second connected arms, and the diameter of the torsional spring 84, 85 on the third and fourth axis pins is greater than the diameter of the torsional spring as the elastic supporting device 56. Therefore, the resilience force of the torsional springs 84, 85 is greater than the resilience force of the elastic supporting device 56 which provides a limiting function for the opening angle of the elastic supporting device 56 and constitutes a limiting device to ensure that the elastic supporting device does not come out of the limiting slot 55 due to too large opening angle.
- the protrusion of the elastic supporting device 56 is mounted with a rotatable roller 58 which can roll along the limiting slot 55 of the fixed block 17 between the distal end and the proximal end, this reduces noises during the movement of the articulation device, and because the original sliding friction can be improved into the rolling friction, the loss can be reduced and the service life can be improved. It can be also conceivable that the improvement can also be applied to the embodiment of the ventilation window or door mentioned above.
- the articulation device can be used not only in ventilation windows or doors but also in other fields to achieve the same or similar functions.
