Abstract
Description
- 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. This invention further relates to an articulation device for such kind of ventilation window or door.
- Inclined roof windows are adapted for inclined roofs, which can provide an abundance of sunshine for buildings and brighten interiors.
- In the prior art, for example, a window 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.
- In order to allow proper and suitable ventilation between the interior and exterior areas of a building, most inclined roof windows are designed to be opened and closed at will by users.
- 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.
- In the prior art related to roof windows, references
DE6903921 as well asEP0458725B1 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. When the window sash is on a locked position relative to the main window frame, 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. When placed in 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. - For example, in the design described in
WO2007/009685 , many disadvantages are visible. Costs are high and manufacturing processes are complicated, thus locking devices such as belonging to this design has definite disadvantages. - In this prior art design, in order to slide among three different positions, the cover member is connected with the control member by using springs on different pivot points, but in such designs, different metal components clash with each other, thus generating undesirable noise when actuated and used. Some improvements have been proposed for this type of locking device such as in
EP053881157 DKPA200600968 - For instance, because the pivot is set under a cover member, when the cover member is opened and on a ventilation position, the cover member is connected with the sliding control member, while the opening angle of the cover member corresponds to the sliding distance. Therefore, the ventilation angle cannot be too large, while in order to facilitate the usage, its pivot can only be arranged under the cover member. Accordingly, 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.
- Further, 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 following known mechanisms (
DK2002/000235 WO02/084043 WO99/51832 WO99/10610 - In
WO2009/141447A1 , the ventilation member additionally has a self-lock function, whereas inWO2002/08043 - For the opening and closing processes, various types of locks and/or locking control mechanisms may be provided. The efficient and smart use of a lock has a direct impact on the efficiency of inclined roof windows.
- Classically, 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.
- There are some disadvantages existing in the structure mentioned above. First, 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. Secondly, the bar- sharp locking element includes pawls which affect the mechanical strength of the locking element. Moreover, the locking element is easy to slip from the cylindrical pin thereby affecting position and the use.
- Various 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 asEP 1762679A1 , describing an assembly for securing a closure member in a closed position including the use of attractive magnets. Furthermore, 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. However, the disadvantages of this design include the number of components and complexity of the design mechanism. - In
CN 102812198 A , a new ventilation window is proposed which is improved for the above-mentioned prior art. 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.
- There are still other disadvantages in the mechanism mentioned above. Because such a ventilation window or door is mounted in a relatively high position, the user is inconvenient to apply forces when operating; specifically, due to opposite directions of the second opening position and the first opening position, the operator can easily open the ventilation window or door in one of the directions (eg. the first opened position) and to be difficult in opening the ventilation window or door in other directions (eg. the second opened position) and the mechanism does not conform to an ergonomic design. In addition, it is difficult for the existing mechanism mentioned above to ensure that when the ventilation window or door is opened to the first opened position or the second opened position, it can still be reliably maintained in the first opened position or the second opened position without external force, that is, there is still a risk of accidental failure in the existing mechanism mentioned above.
- In light of prior art mentioned above, 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 novel and inventive ventilation opening adjustment and locking mechanism that is simpler, low noise, lower requirements for processing procedure and higher reliability. In addition, 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.
- In order to solve the aforementioned technical problems and overcome some of the inherent problems found in the prior art, 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. According to the invention, 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.
- Further, the 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:
- a plurality of axis pin, comprising: a first axis pin coaxial with the first axis, a second axis pin coaxial with the second axis, a third axis pin coaxial with a first movable axis parallel to the first axis, a fourth axis pin coaxial with a second movable axis parallel to the first movable axis, and a distance between the first axis pin and the fourth axis pin is equal to a distance between the second axis pin and the third axis pin;
- two connected arms, both ends of one connected arm respectively hinged to the first axis pin and the fourth axis pin, and both ends of the other connected arm respectively hinged to the second axis pin and the third axis pin,
- two rigid connector, wherein one connector is mounted on the fixed block and both ends are respectively hinged to the first axis pin and the second axis pin, the other connector is fixedly mounted on the pivoting flap and both ends are respectively connected to the third axis pin and the fourth axis pin; when the pivoting flap rotates around the axis, said two rigid connector are adapted for delivering partial stress on the connected arm to the fixed block;
- an elastic supporting device, disposed on a middle part of one of the two connected arms, so that the connected arm can elastically pivot around the second axis that the pivoting flap can be kept in the second opened position.
- The elastic supporting device is 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. Thus, when the ventilation window or door is opened to the second opened position by a user, the protrusion in the limiting slot can provide resilience force for the torsional spring, so as to help balancing the gravity of the pivoting flap by the resilience force, thus the pivoting flap can be kept in the second opened position.
- In another aspect of the invention, in the hinged device:
- the two connected arm comprising a first connected arm and a second connected arm, the first connected arm comprising a first axis sleeve hinged to the first axis pin, and a second axis sleeve hinged to the fourth axis pin; the second connected arm comprising a third axis sleeve hinged to the second axis pin, and a fourth axis sleeve hinged to the third axis pin;
- the two rigid connectors comprising a first rigid connector and a second rigid connector, the first rigid connector comprising a fifth axis sleeve hinged to the first axis pin and a sixth axis sleeve hinged to the second axis pin, and the second rigid connector comprising a seventh axis sleeve hinged to the third axis pin and a eighth axis sleeve hinged to the fourth axis pin;
- The first movable axis and the second movable axis extend along the length of the flap, and when the flap is in its closed position, the first movable axis coincides with the first axis, the second movable axis coincides with the second axis.
- In another aspect of the invention, when the pivoting flap is in its closing position, the first rigid connector and the second rigid connector face each other with a distance in order to avoid interference from occurring.
- In another aspect of the invention, 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.
- In another aspect of the invention, 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.
- According to the invention, 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 of the present invention 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. At the same time, because each of the axis and the axis sleeve is always hinged to operate together, 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. And 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.
- Another aspect of the invention further comprises an articulation device, adapted for use in the ventilation window or door, comprising:
- a fixed block, adapted for mounting on a sash or a door frame,
- a plurality of axis pin, comprising: a first axis pin defining the first axis, a second axis pin defining the second axis, a third axis pin defining a first movable axis parallel to the first axis, a fourth axis pin defining a second movable axis parallel to the first movable axis, wherein a distance between the first axis pin and the fourth axis pin is equal to a distance between the second axis pin and the third axis pin;
- two connected arms, both ends of one connected arm respectively hinged to the first axis pin and the fourth axis pin, and both ends of the other connected arm respectively hinged to the second axis pin and the third axis pin,
- two rigid connector, wherein, one connector is mounted on the fixed block and both ends are respectively connected to the first axis pin and the second axis pin, both ends of the other connector are respectively connected to the third axis pin and the fourth axis pin;
- an elastic supporting device, disposed on a middle part of one of the two connected arms, so that the connected arm can elastically pivot around the second axis or the first axis and be supported relative to the fixed block.
- The articulation device of the present invention 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. At the same time, when the user opens the articulation device around the second axis, the resilience force of the elastic supporting device can be balanced and stabilized in the opened state, further preventing the risk of accidental failure.

Figure 4 , the pivotingflap 14 and thearticulation device 16 of theventilation system 10 is shown in a second opened position. Please be noted that the cross section is taken along the middle part of the pivotingflap 14, that is, along the middle line of thelocking device 112. - Referring now to
Figure 4A , a cross-sectional view of thearticulation device 16 ofFigure 4 is shown in a second opened position. -
Figure 5A shows anexemplary window 100 with the pivotingflap 14 in the first opened position andFigure 5B shows a cross-sectional schematic perspective view of the window. Themain frame 102 is illustrated in relation toventilation system 10. Aglass supporting sash 104 is arranged to tilt within themain frame 102. Here, inFigures 5A and5B , thesash 104 is shown in a closed position. - With reference to
Figure 5B , aventilation passage 106 is shown where air from an interior space and an exterior space is exchanged freely without any obstacles. Theventilation passage 106 includes aninterior opening 108 and anexterior opening 110 in thewindow 100. - Here, in the first opened position, the pivoting
flap 14 is opened in a way where the air exchange can occur from a bottom configuration of theflap 14 where theflap 14 is opened with theopening 108 facing upward. -
Figure 6A shows an exemplary window with the pivotingflap 14 in the second opened position andFigure 6B shows a cross-sectional schematic perspective view of thewindow 100. In the second opened position, the pivotingflap 14 is opened in a way where the air exchange can occur from an upper configuration of theflap 14 where theflap 14 is opened with theopening 108 facing downward. - As can be seen by the arrows representing the flow of air exchanged from the interior space and an exterior space via the
interior opening 108 and theexterior opening 110 in thewindow 100, the fact thatwindow 100 can provide bidirectional ventilation passages offers the advantage that air can be exchanged in a upward direction as shown inFigure 5B and in an downward direction inFigure 6B . That is, the user may decide that it is more desirable to open theventilation passage 106 in a downward direction rather than in an upward direction because of heat or cold or humidity control. - The user may also adjust the size and/or length of the
ventilation passage 106 by varying degrees of opening size by adjusting the amount by which the user flips open thebidirectional pivoting flap 14, as desired. - Referring to
Figure 6B , theventilation system 10 of the present invention is shown in awindow 100. Thewindow 100 includes amain frame 202 and asash unit 204. Thesash unit 204 includes asash component 204A andsash component 204B. This design and arrangement of having two distinct and separate sash components provide the additional advantage of having modular components for manufacturing which can lower costs and provides ease of assembly. - Referring now to
Figure 7 ,window 100 is shown with thesash 104 in an opened position. - Now, a more precise mechanism and operation of the bidirectional
pivoting ventilation system 10 having thebidirectional pivoting flap 14 will be described in greater detail. - Referring to
Figure 8 , a locking fitting 112 of theventilation system 10 ofFigure 1 is illustrated. The locking fitting 112 is adapted to lock thesash 104 to themain frame 102 in a closed position. The locking fitting 112 includes alocking mechanism 114 mounted on thesash 104 inside theventilation passage 106. Thelocking mechanism 114 has a single locking function. - Referring back to
Figures 3 ,4 and8 , the pivotingflap 14 is mounted on thesash 104 and connected to thelocking mechanism 114. With reference toFigure 3A , the pivotingflap 14 is adapted to pivot around a first axis (A1) which is stationary relative to thesash 104, between a closed position in which theflap 14 shuts theinterior opening 108 while setting thelocking mechanism 114 in a locked position and a first opened position in which theflap 14 is pivoted to open theventilation passage 106 while setting the locking mechanism in an unlocked position. - Further, with reference to
Figure 4 , the pivotingflap 14 is adapted to pivot around a second axis (A2) which is stationary relative to thesash 104 and parallel to the first axis (A1), between the closed position of theflap 14 and a second opened position in which theflap 14 is pivoted to open theventilation passage 106 while keeping thelocking mechanism 114 in the locked position. - Referring now to
Figure 3A , details of thearticulation device 18 are described. Thearticulation device 18 has a fixedblock 17 secured to thesash 104. Thearticulation device 16 is assembled to thesash 104 by the fixedblock 17. The pivotingflap 14 is connected to thearticulation device - Specifically, referring to
Figures 3 and3A in combination withFigures 10 and11 , the secondrigid connector 600b is fixed on the fixedblock 17 by the through hole on its body, for example, by a bolt or a screw or by snapping. In addition, there is no limitation to the number of the through hole. The second rigid connector has a extended end extending from its body, the extended end has a seventh arranged on thethird axis pin 87c coaxial with the first movable axis B1 and an eighth axis sleeve arranged on thefourth axis pin 87d coaxial with the second movable axis B2, so as to enable the secondrigid connector 600b respectively pivots the first movable axis B1 and the second movable axis B2. Alternatively, the secondrigid connector 600b may be divided into two separate parts, each of which has at least one said through hole, one of which is hinged to thethird axis pin 87c, and the other one of which is hinged to thefourth axis pin 87d. The firstrigid connector 600a is fixed on the pivotingflap 14 by the through hole on its body, for example, by a bolt or a screw or by snapping. The firstrigid connector 600a has a extended end extending from its body, the extended end has afifth axis sleeve 89d arranged on thefirst axis pin 87a coaxial with the first axis Aland a sixth axis sleeve arranged on thesecond axis pin 87b coaxial with the second axis A2. Alternatively, the firstrigid connector 600a may be divided into two separate parts, each of which has at least one said through hole, one of which is hinged to thefirst axis pin 87a, and the other one of which is hinged to thesecond axis pin 87b. - When the second
rigid connector 600b rotates under stress, the stress of the first and the secondconnected arms rigid connector 600a to reduce the probability of deformation of the first and the secondconnected arms - The
first axis pin 87a and thefourth axis pin 87d are respectively nested in a first axis sleeve and a second axis sleeve on both ends of the firstconnected arm 80a. Thesecond axis pin 87b and thethird axis pin 87c are respectively nested in a third axis sleeve and a fourth axis sleeve on both ends of the secondconnected arm 80b. A length of the firstconnected arm 80a is the same as a length of the secondconnected arm 80b so as to ensure a distance between the first axis A1 and the second movable axis B2 is equal to a distance between the second axis A2 and the first movable axis B1. -
Figure 10 shows another view of the operation of the pivotingflap 14 in relation to thearticulation device 16. The first movable axis B1 and the second movable axis B2 extending along a length of theflap 14 coincide with the first and second axis (A1, A2) when theflap 14 is in its closed position. - In certain embodiment, the third and the fourth axis pin are wound with
torsional springs slots blocks 17, and the other end of which is supported on supportingslots - Referring now to
Figure 9 , this view shows thelocking mechanism 114 of the locking fitting 112 ofFigure 8 in greater detail. Anactuation linking device 70 for thelocking mechanism 114 is hinged to theflap 14 to pivot around a second movable axis B2. The axis B2 extends along a length of theflap 14 and is displaceable relative to the sash 104 (not shown). Theactuation linking device 70 also includes afirst rod 71 hinged to theflap 14. Thefirst rod 71 is also hinged to theactuation slider 72 of thelocking mechanism 114. Theactuation slider 72 controls thelocking mechanism 114 in the unlocked or locked position. Among them, the position shown inFIG. 9 is the unlocked position. - In addition, when the
flap 14 pivots between its closed position and its second opened position, the second movable axis B2 coincides with the second axis A2. At this time, thelocking mechanism 114 is in the locked position, as shown inFIG. 9A . - In addition, there is a hollow space in the middle of the second connecting
rod 80b within which an elastic supportingdevice 56 is also provided in. The elastic supporting device is a torsional spring member having elasticity, and is pivotably disposed on an axis pin in the middle of the second connectingrod 80b that runs through the hollow space. Optionally, the elastic supporting device may also be mounted in the middle of the first connectingrod 80a. One end of the elastic supporting device is fixed on the connected arm, and the other end has a protrusion. Preferably, the elastic supportingdevice 56 is also a torsional spring, and its diameter is smaller than the torsional springs 84, 85 on the first and second axis pins. For example, the torsional springs 84, 85 have a diameter of 1.2 to 1.6 mm. The torsional spring as an elastic supportingdevice 56 has a diameter of 1.0 to 1.4 mm; most preferably, thetorsional spring device 56 has a diameter of 1.2 mm. Since both ends of the torsional springs 84, 85 on the third and fourth axis pins are respectively supported by the supporting slots in the fixedblock 17 and the supporting slots on the first and second connected arms. The diameter of the torsional springs 84, 85 on the third and fourth axis pin are respectively larger than the diameter of the torsional spring as the elastic supportingdevice 56. Therefore, the resilience force of the torsional springs 84, 85 is greater than the resilience force of the elastic supportingdevice 56, which plays a limiting function for the opening angle of the elastic supportingdevice 56, and constitutes a limiting device to ensure that the elastic supporting device does not come out of the limiting slot 55 (see below) due to too large opening angle. Thus, when in the closed state, the torsional springs 84, 85 on the first and second axis pins ensure that the first connectingrod 80a and the second connectingrod 80b remain closed at all times, and fix the pivotingflap 14 in the inner window. In this way, the pivotingflap 14 and the inner window are in a closed state to provide resilience force. When in the first opened position, the secondrigid connector 600b under the first connectingrod 80a pivots around the second movable axis B2, and thetorsional spring 84 provides resilience force to ensure that the pivotingflap 14 is opened. And when the first opened position is to be closed, thetorsional spring 84 provides resilience force, which makes closing the window feel better. - With reference to
Figures 2A and4A , in some embodiments, the interior of the fixed block has a cavity further including a limitingslot 55. The limitingslot 55 is located inside the fixedblock 17 to receive the protrusion. In particular, there is also a recess in the limitingslot 55 in the present embodiment. When the pivoting flap is in the closed position and the first opened position, the elastic supportingdevice 56 is located at the distal end of the limitingslot 55. When the pivoting flap is in the second opened position, the elastic supportingdevice 56 is located at the proximal end of the limitingslot 55, that is, the proximal end is a recess, so as to provide sufficient friction to the elastic supportingdevice 56 in the second opening position. The elastic supportingdevice 56 achieves force balance under the action of its own elastic force and frictional force, and is supported at this position. In particular, the protrusion of the elastic supportingdevice 56 snaps into the limitingslot 55 to stabilize the turning angle of the pivoting flap. Specifically, the elastic supportingdevice 56 is maintained in the limitingslot 55 by the tension of the torsional spring so that the flap can be maintained in the selected second opened position. - In this way, when in the second opened position, the elastic supporting
device 56 on the second connectingrod 80b rotates around the axis pin. After the elastic supportingdevice 56 is opened, the pivotingflap 14 is in a fixed state due to frictional force and resistance force and fails to rebound back causing the pivotingflap 14 to close. When the second opened position is to be closed, thetorsional spring 85 on the second connectingrod 80b will provide closing assisting force. In another embodiment, the body of the firstrigid connector 600a snaps onto an intermediate plate, which is fixed to theflap 14 by a screw penetrating through a through hole in its surface. - According to another aspect of the present invention, it provides an articulation device for such ventilation windows or doors mentioned above.
- Such articulation device includes the following components:
Fixed block for fixing to a target object that needs to achieve an articulation function, such as a window frame or a door frame. - A plurality of axis pins include a
first axis pin 87a defining a first axis A1, asecond axis pin 87b defining a second fixed axis A2, and athird axis pin 87c and afourth axis pin 87d. Thethird axis pin 87c defines a first movable axis B1 parallel to the first axis A1. Thefourth axis pin 87d defines a second movable axis B2 parallel to the first movable axis B1. The distance between thefirst axis pin 87a to thefourth axis pin 87d is equal to the distance between thesecond axis pin 87b and thethird axis pin 87c. - The first
rigid connector 600a, which includes a body having a through hole, can be secured to an external mount, such as by bolts or screws or by snapping. The firstrigid connector 600a has an extended end extending from the main body. The extended end of the firstrigid connector 600a has a fifth and a sixth axis sleeve. Thefifth axis sleeve 89a is disposed on thefirst axis pin 87a, and thesixth axis sleeve 89b is disposed on thesecond axis pin 87b. Optionally, the firstrigid connector 600a can be divided into two separate parts, each of which has at least one through hole, and one separate part is hinged on thefirst axis pin 87a, and another separate part is hinged on thesecond axis pin 87b, in order to save material. - The second
rigid connector 600b includes a body with a through hole, including an extended end extending from the body, an extended end having a seventh and an eighth sleeve, and theseventh sleeve 89c disposed on thethird axis pin 87c coaxial with a first movable axis B1, theeighth axis sleeve 89d is disposed on thefourth axis pin 87d coaxial with the second movable axis B2, so that the secondrigid connector 600b can respectively pivot around the first movable axis B1 and the second movable axis B2. Optionally, the secondrigid connector 600b can be divided into two separate parts, each part has at least one through hole, and one separate part is hinged on thethird axis pin 87c, another separate part is hinged on saidfourth axis pin 87d. - For the first and second
connected arms connected arm 80a are respectively hinged to thefirst axis pin 87a and thefourth axis pin 87d, and both ends of the secondconnected arm 80b are respectively hinged to thesecond axis pin 87b andthird axis pin 87c. There is a hollow space in the middle of the secondconnected arm 80b in which an axis pin is traversed. - The elastic supporting
device 56 is generally a torsional spring including a first end disposed on an axis pin in a hollow space in the middle of the secondconnected arm 80b, and a second end having a protrusion accommodated in the fixedblock 17. - Specifically, the cavity inside the fixed
block 17 further includes a limitingslot 55. The limitingslot 55 is located inside the fixedblock 17 to receive a protrusion. In particular, there is also a recess in the limitingslot 55 in the present embodiment. When the articulation device is pivoted around the second axis A2, the elastic supportingdevice 56 is located at the distal end of the limitingslot 55. When the articulation device is pivoted around the first axis A1, the elastic supportingdevice 56 is located at the proximal end of the limitingslot 55. The proximal end is a recess, so as to provide sufficient friction to the elastic supportingdevice 56 during this period. The elastic supportingdevice 56 can achieve force balance under the action of its own resilience force and frictional force, and is supported at this position. - In certain embodiment, the third and fourth axis pins are wound with
torsional springs slots block 17, and the other end of which is supported in the supportingslots - Preferably, 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. For example, the torsional springs 84, 85 have a diameter of 1.2 to 1.6 mm. The torsional spring as the elastic supportingdevice 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 supportingdevice 56 has a diameter of 1.2 mm. Since both ends of the torsional springs 84, 85 on the third and fourth axis pins are respectively supported by the supporting slots in the fixedblock 17 and the supporting slots on the first and second connected arms, and the diameter of thetorsional spring device 56. Therefore, the resilience force of the torsional springs 84, 85 is greater than the resilience force of the elastic supportingdevice 56 which provides a limiting function for the opening angle of the elastic supportingdevice 56 and constitutes a limiting device to ensure that the elastic supporting device does not come out of the limitingslot 55 due to too large opening angle. - Referring to
Figure 12 , in another modified embodiment, the protrusion of the elastic supportingdevice 56 is mounted with arotatable roller 58 which can roll along the limitingslot 55 of the fixedblock 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. - In addition, a person skilled in the art can easily conceive that 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.
- The above embodiments are only examples, and do not tend to limit the scope of the present invention. On the basis, a person skilled in the art can expect other embodiments that can achieve the same function within the protection scope of the claims of the present invention.
