Description

Door actuator and door unit
Technical Field
The present invention relates to a door actuator for opening and/or closing a door, a door unit including the same, and a regulating valve.
Background
Conventionally, a door actuator is known which includes a hydraulic mechanism for actuating a door and a hydraulic fluid for the hydraulic actuating mechanism. Furthermore, conventional door actuators include a valve passage in their housing through which hydraulic fluid of the hydraulic actuation mechanism flows during opening and/or closing of the door. In order to adjust the damping effect of the door actuator on the closing and opening movements of the door, conventional door actuators usually comprise a regulating valve for regulating the flow of hydraulic fluid through a valve channel. By changing the position of the regulator valve in the valve passage, the flow of hydraulic fluid through the valve passage is increased or inhibited. A problem with these conventional regulator valves is that loosening the regulator valve to increase the flow of hydraulic fluid in the valve passage can result in inadvertent removal of the valve, resulting in leakage of hydraulic fluid in conventional door actuators.
Disclosure of Invention
It is an object of the present invention to provide a door actuator for opening and/or closing a door, which door actuator can prevent an adjusting valve from being accidentally removed from the door actuator.
This object is achieved by the features of the independent claims. The dependent claims contain advantageous embodiments of the invention.
The door actuator for opening and/or closing a door of the present invention includes a housing configured to contain a hydraulic actuating mechanism for actuating the door and a hydraulic fluid of the hydraulic mechanism. Wherein the housing further comprises a valve channel for hydraulic fluid and at least one orifice in fluid connection with the valve channel. In addition, the door actuator comprises at least one regulating valve for regulating the flow of hydraulic fluid in the valve channel, wherein the at least one regulating valve is inserted into the at least one orifice. The at least one regulator valve includes a valve stop element having at least one snap-fit portion configured to snap into an undercut of the orifice upon insertion of the regulator valve.
The door actuator of the present invention has the advantage of preventing the regulator valve from being accidentally removed from the orifice by a valve stop element that snaps into an undercut of the orifice when the regulator valve is inserted. Thus, the regulator valve and its valve stop element may be easily inserted into the orifice and, when a user or installer regulates the flow of hydraulic fluid through the valve passage via the regulator valve, accidental removal of the regulator valve is advantageously prevented.
Preferably, the snap-fit portion of the valve stop element is configured to be elastically deformed in a direction perpendicular to the axial direction of the valve stop element when the regulating valve is inserted into the orifice. In other words, the snap-fit portion is configured to be elastically deformed when the regulator valve is inserted, so that the regulator valve can be easily inserted into the orifice. Advantageously, the elasticity of the snap-fit portion allows the snap-fit portion to snap into the undercut of the orifice once the snap-fit portion reaches said orifice during insertion of the regulating valve.
Advantageously, the snap-fit portion is a snap finger comprising an outer peripheral portion, which snap finger has an inclined portion inclined from the axial direction of the valve stop element in the fully inserted state of the valve stop element. In other words, the inclined portion of the snap finger has an angle between 0 ° and 90 ° and not including 0 ° and 90 ° with respect to the axial direction of the valve stop element. This has the advantage that the snap-fit part can be easily inserted into the aperture while being deformed, in particular elastically deformed. The inclined portion particularly allows easy sliding of the snap finger into the aperture of the housing.
More advantageously, the outer peripheral portion of the snap-fit portion has a non-constant diameter in the axial direction, wherein the diameter increases in the direction towards the end of the regulating valve, wherein the valve stop element is located at the end. This has the advantage that the regulating valve can be easily inserted into the orifice.
More advantageously, the undercut of the orifice is a groove formed in at least a portion of the circumferential direction of the orifice. In other words, the undercut of the orifice is preferably formed in a partially circular shape or a completely circular shape in a circumferential plane perpendicular to the axial direction of the orifice. This has the advantage that the valve stop element can be firmly attached to the orifice and prevent the regulating valve from being accidentally removed from the orifice.
More advantageously, the length of the undercut in the axial direction of the orifice is longer than the length of the valve stop element in the axial direction of the valve stop element. Preferably, the length of the undercut is longer than the length of the snap-fit portion of the valve stop element. This has the advantage that the valve stop element, in particular the regulating valve, can be moved in a variable manner within the orifice, while also preventing the valve stop element, in particular the regulating valve, from being accidentally removed from the orifice.
Preferably, the snap-fit portion comprises, in particular in a top surface of the snap-fit portion, a recess configured to receive a tool for elastically deforming the snap-fit portion during insertion and/or removal of the valve stop element into and/or from the orifice. This has the advantage that the valve stop element can be easily removed from the orifice, wherein the valve stop element is still prevented from being accidentally removed.
More preferably, the valve stop element and the undercut of the orifice are arranged in an end portion of the orifice opposite the valve channel of the housing. This has the advantage that the valve stop element and the regulating valve can be easily inserted into the aperture even after assembly and/or installation of the door actuator.
Advantageously, the valve stop element comprises two or more and/or five or less snap-fit portions. This has the advantage that the valve stop element can be securely inserted and attached to the aperture. Furthermore, the valve stop element may prevent accidental removal of the regulator valve even if one of the snap-fit portions is damaged.
Advantageously, the valve stop element is integral with the regulating valve. This has the advantage that no additional components and/or processing are required to provide a means of preventing the regulator valve from being accidentally removed from the orifice, thereby also reducing the manufacturing cost of the door actuator.
More advantageously, the regulating valve and/or the valve stop element are made of plastic. The control valve and/or the valve stop element can be made of or comprise polyoxymethylene and/or polyurethane. This has the advantage that the regulating valve and/or the valve stop element can be manufactured easily by preferably low-cost materials, for example by injection molding.
More preferably, the regulating valve and/or the valve stop element may comprise a variety of materials, such as metal and/or plastic. It is particularly preferred, among other things, for the snap-fit part of the valve stop element to comprise or be made of plastic, in particular polyoxymethylene and/or polyurethane.
The invention also relates to a door unit comprising a door and a door actuator according to any of the preceding advantageous examples. Wherein the hydraulic actuation mechanism is drivingly connected to the door or to a lever assembly, wherein the lever assembly is connected to the doorframe of the door such that actuation of the actuation mechanism opens or closes the door. Wherein the regulating valve can regulate the damping amount when the door is opened or closed.
This has the advantage that a door unit may be provided in which an unintentional removal of the regulating valve may be prevented, for example when a user or installer tries to adjust the damping of the door.
The invention also relates to a regulating valve for regulating the flow of hydraulic fluid in a valve channel of a door actuator, preferably the aforementioned door actuator. The regulating valve is preferably designed according to any of the preceding advantageous examples.
The regulator valve is configured to be inserted into an aperture of a housing of the door actuator, and the regulator valve includes a valve stop element having at least one snap-fit portion configured to snap into an undercut of the aperture upon insertion of the regulator valve.
The snap-fit portion is preferably a snap finger comprising an outer peripheral portion having an inclined portion inclined from the axial direction of the valve stop element.
More advantageously, the outer peripheral portion of the snap-fit portion has a non-constant diameter in the axial direction, wherein the diameter increases in the direction towards the end of the regulating valve, wherein the valve stop element is located at the end. This has the advantage that the regulating valve can be easily inserted into the aperture.
The snap-fit portion preferably comprises, in particular in a top surface of the snap-fit portion, a recess configured to receive a tool for elastically deforming the snap-fit portion during insertion and/or removal of the valve stop element into and/or from the orifice.
The valve stop element preferably comprises two or more and/or five or less snap-fit portions.
The valve stop element is preferably integral with the regulating valve.
The control valve and/or the valve stop element are preferably made of plastic, in particular of polyoxymethylene and/or polyurethane.

Detailed Description
Fig. 1 shows a schematic perspective view of a housing 2 of a door actuator 1 according to a first embodiment of the invention.
The door actuator 1 includes a housing 2, and the housing 2 is formed to house a hydraulic actuating mechanism for opening and/or closing a door 101 (see: fig. 5). The housing 2 comprises two through holes 18, the through holes 18 receiving a spindle connected to the hydraulic actuating mechanism, the spindle being driven by the hydraulic actuating mechanism.
Furthermore, the door actuator 1 comprises at least one orifice 6, in this embodiment a plurality of orifices 6, each orifice 6 containing a regulating valve 5. The configuration and function of the regulating valve 5 will be explained with reference to fig. 2 to 4.
Wherein fig. 2 shows a schematic cross-sectional view of a regulating valve 5 of the door actuator 1 according to the present embodiment of the invention.
The regulating valve 5 is arranged in an orifice 6 of the housing 2. Furthermore, the housing 2 comprises at least one valve channel 3. The hydraulic actuation mechanism drives or dampens the door during opening and/or closing of the door. During these movements, the hydraulic fluid of the hydraulic actuating mechanism flows through the housing 2, in particular through the valve channel 3 of the housing 2.
As can be seen from fig. 2, the regulating valve 5 comprises a valve plug 20, the valve plug 20 being configured to at least partially seal the valve channel 3. In the state shown in fig. 2, the regulating valve 5, which is not fully inserted (compare fig. 3a to 3 c), does not seal the valve passage 3, thus allowing hydraulic fluid to flow through said valve passage 3. In the fully inserted state, the regulating valve 5 also seals the orifice 6 so that hydraulic fluid cannot escape from the orifice 6.
The depth of the regulating valve 5 in the aperture 6 of the housing 2 is arranged (by the installer or user) so as to configure the damping force and/or the opening force of the door actuator 1. For example, if the regulator valve 5 is located deeper in the orifice 6, the valve plug 20 of the regulator valve 5 restricts the flow of hydraulic fluid through the valve passage 3 by at least partially sealing the valve passage 3. In this embodiment, this is achieved by the threaded portion 19 of the regulating valve 5. A user or installer may use a tool such as a screwdriver to tighten or loosen the regulator valve 5.
The regulating valve 5 of the present embodiment further includes a valve stopping member 7, and the valve stopping member 7 prevents the regulating valve 5 from falling out of the orifice 6 even when the regulating valve 5 is released. Details of the valve stop element 7 will be discussed with reference to fig. 3a to 3 c.
Fig. 3a, 3b and 3c show schematic detail views of a cross section of the regulating valve 5 of the door actuator 1 according to a first embodiment of the invention. Specifically, fig. 3a shows a state in which the regulator valve 5 starts to be inserted into the orifice 6 of the housing 2. Furthermore, fig. 3b shows the advanced state of insertion, and fig. 3c shows the state of complete insertion of the regulating valve 5 in the orifice 6 of the housing 2. The direction of insertion of the regulating valve 5 into the orifice 6 corresponds to the axial direction 11 of the valve stop element 7. Once fully inserted, the depth of the regulator valve 5 may be set via tightening or loosening the regulator valve 5 in the orifice 6.
As shown in fig. 1, the control valve 5, in particular the valve stop element 7 of the control valve 5, is circular in plan view.
As can be seen in fig. 3a, the valve stop element 7 of the regulating valve 5 comprises two snap-fit portions 9. These snap-fit portions 9 are configured to be elastically deformable (as seen in fig. 3 b) and snap into the undercuts 8 of the aperture 6.
For example, the snap-fit portion 9 and the undercut 8 are semi-circular in shape in plan view. That is, the snap-fit portion 9 is formed in at least a part of the circumferential direction 16, the circumferential direction 16 lying in a plane perpendicular to the axial direction 11. The portion of the circumferential direction 16 in which the snap-fit portion 9 is provided corresponds to the portion of the circumferential direction 16 in which the undercut 8 is provided.
In another example, the snap-fit portion 9 and/or the undercut 8 of the aperture 6 may comprise a full circular shape. That is, the snap-fit portion 9 and/or the undercut 8 of the aperture 6 may be formed along the entire circumferential direction 16 in top view. In this case, the valve stop element 7 may comprise one or more slits in the axial direction 11, which separate the snap-fit parts 9.
The valve stop element 7 and the undercut 8 of the orifice 6 are arranged in the end portion of the orifice 6 opposite the regulating valve 5. In other words, the valve stop element 7 and the undercut 8 are arranged in an outer part of the housing 2.
The snap-fit portion 9 of the present embodiment is a snap finger which comprises in its outer circumference an inclined portion 10 which is inclined from the axial direction 11 of the valve stop element 7.
As can be seen from fig. 3b, when the regulating valve 5 is inserted into the orifice 6, the orifice 6 forces the elastic snap-fit portion 9 to be elastically deformed in a direction 17 perpendicular to the axial direction 11. More specifically, the bending direction of the snap-fit portion 9 is a vector lying in a plane spanned by the axial direction 11 and a direction 17 perpendicular to the axial direction 11. As shown by a comparison of fig. 3a and 3b, the top of the snap-fit portion 9 moves along a semi-circular curve towards the center of the valve stop element 7 (indicated by axial direction 11).
When in the fully inserted state, as shown in fig. 3c, the snap-fit portion 9 of the valve stop element 7 snaps into the undercut 8 of the aperture 6. Thus, when the regulator valve 5 is moved outwardly from the orifice 6 in the axial direction 11 (upward in fig. 3a to 3 c), the snap-fit portion 9 abuts against the undercut 8, preventing the regulator valve 5 from falling out of the orifice 6.
The undercut 8 of this embodiment has substantially the same shape as the valve stop element 7, in particular as the snap-fit portion 9 of the valve stop element 7. In this embodiment, the length 12 of the undercut 8 in the axial direction 11 is the same as the length 13 of the valve stop element 7 in the axial direction 11.
The width of the undercut 8 in the direction 17 perpendicular to the axial direction is larger than the width of the valve stop element 7, in particular the snap-fit portion 9 of the valve stop element 7, in the direction 17. Thereby, the valve stop element 7 may be loosely fitted in the undercut 8 of the orifice 6. This allows adjustment of the valve 5, since the valve stop element 7 can be moved in a limited manner within the undercut 8.
In another example of the aforementioned configuration, the length 12 of the undercut 8 may be longer than the length 13 of the valve stop element 7 in the axial direction 11, in particular longer than the length 13 of the snap-fit portion 9 of the valve stop element 7 in the axial direction 11. In this way, a range of movement in the axial direction for the valve locking element 7, in particular the valve locking element 7 of the control valve 5, can be formed in the opening 6 for setting the flow of hydraulic fluid in the valve channel 3.
Fig. 4 shows a schematic detail view of a cross section of the regulating valve 5 of the door actuator 1 according to a second embodiment of the invention.
As can be seen from fig. 4, the valve stop element 7 of the regulating valve 5 comprises a recess 15 in the upper surface 14 of the valve stop element. These recesses 15 are configured to receive a tool (not shown), such as, for example, a pair of pliers or tweezer tools, in order to selectively remove the regulating valve 5 from the orifice 6.
Thereby, the tool is able to elastically deform the snap-fit portion 9 in the same way as when inserting the regulating valve 5 into the orifice 6, and thereby allow removal of the regulating valve 5 from the orifice 6.
The shape of the recess 15 is not limited to the shape shown in fig. 4. For example, the recess 15 may be hook-shaped or L-shaped, so that the tool may also exert a pulling force in the axial direction 11 on the recess 15 without slipping out of the recess 15.
In the foregoing embodiment, the regulating valve 5 and the valve stop member 7 are integrally formed, i.e., the regulating valve 5 and the valve stop member 7 constitute a single member.
Furthermore, the regulating valve 5 and the valve stop element 7 can each or both be made of metal or plastic, in particular of polyoxymethylene and/or polyurethane. Each of the regulating valve 5 and the valve stop element 7 may be made of the same material, or each of the regulating valve 5 and the valve stop element 7 may comprise or be formed of different materials and fused together, i.e., via welding or brazing.
In addition, the regulating valve 5 can be formed via injection molding, in particular integrally with the valve stop element 7.
Fig. 5 shows a schematic view of the door unit 100 of the present invention.
The door unit 100 includes the door 101 and the door actuator 1 according to the above-described embodiment. The hydraulic actuating mechanism 4 is connected to a lever assembly 102, wherein the lever assembly 102 is also connected to a door frame 103 of the door 101. More specifically, the main shaft of hydraulic actuation mechanism 4 is connected to rod assembly 102. The spindle is actuated, more specifically rotated, by an actuating mechanism 4.
By rotating the main shaft, the hydraulic actuator 4 opens or closes the door 101. Further, the hydraulic actuation mechanism 4 of the door actuator 1 damps the door 101 when the door 101 is closed.
As explained with reference to fig. 1 to 4, the door actuator 1 comprises at least one orifice 6, in particular a plurality of orifices 6, and a regulating valve 5 arranged in these orifices 6.
As shown in fig. 5, the door actuator 1 may include an orifice 6 and a regulator valve 5 on either side or sides of the housing 2 of the door actuator 1. Thus, the regulating valve 5 is easily accessible to a user or installer, in particular irrespective of the installation orientation of the door actuator 1.
