Description

ACCESS MEMBER MANIPULATOR AND SYSTEM
TECHNICAL FIELD
The present disclosure generally relates to a manipulator for opening and/or closing an access member, such as a door. In particular, a manipulator for opening and/or closing an access member and a system comprising a frame, an access member, at least one hinge and a manipulator are provided.
BACKGROUND
Various types of manipulators for operating doors are known.
US 2005091928 Ai discloses an automatic door opener attached to an upper portion of a door frame and comprising an arm pivotally connected to its housing and having a roller at its free end. When swung, the arm pushes the door through a pilot plate. When the arm is retracted, the door is closed either by the action of the door closer or by the arm.
The door opener in US 2005091928 Ai has a bulky and complicated structure that, for example, is easy to break.
SUMMARY
One object of the present disclosure is to provide a manipulator for opening and/or closing an access member, with a simple, yet robust design.
A further object of the present disclosure is to provide a manipulator for opening and/or closing an access member that may be concealed when the access member is closed.
A further object of the present disclosure is to provide a manipulator for opening and/or closing an access member that has a good strength to survive abuse. A further object of the present disclosure is to provide a manipulator for opening and/or closing an access member that provides a high opening force and/or a high closing force to the access member.
According to one aspect, there is provided a manipulator for opening and/or closing an access member coupled to a frame by means of at least one hinge, where the manipulator comprises an actuator configured to provide a substantially linear actuating movement in a first direction, and a
transmission mechanism configured to transmit the actuating movement in the first direction provided by the actuator to an opening or closing movement of the access member.
The manipulator may alternatively be referred to as a door opener or door closer, when used to manipulate a door. The access member may for example be constituted by a door or a door leaf. The access member may be rigid and have a flat appearance. The frame may be constituted by an opening in a wall. Alternatively, the frame may be constituted by a structure attachable to an opening in a wall.
The at least one hinge may be of any suitable type to rotationally couple the access member to the frame and rotationally support the access member between a closed position and an open position. The hinge may for example be constituted by a barrel hinge substantially as shown in
US 2014090205 Ai. Alternatively, or in addition, the hinge may be constituted by a concealed hinge substantially as shown in
US 2015259960 Ai.
With a barrel hinge, the access member may rotate with respect to the frame about a single hinge axis. In this case, the transmission mechanism may be configured to transmit the actuating movement in the first direction provided by the actuator to a rotational movement of the access member.
With a concealed hinge, the access member may "move out" a bit during rotation to enable, for example, a 1800 rotation with respect to the frame. However, also in this case, the transmission mechanism is considered to be configured to transmit the actuating movement in the first direction provided by the actuator to a rotational movement of the access member.
The actuator may be of various types. For example, the actuator may be constituted by a mechanical actuator such as a screw actuator, a hydraulic actuator, a pneumatic actuator, an electro-mechanical actuator, a linear motor etc. The actuator may be electrically powered in any suitable manner.
Also the transmission mechanism according to the present disclosure may adopt a wide range of different designs. In many realizations, the
transmission mechanism comprises or is constituted by a linkage.
A closed position may be constituted by a position where the access member is substantially flush with, or substantially parallel with, the frame. An open position may be constituted by a position where the access member is angled with respect to the frame. In the open position, an angle between the access member and the frame may be, for example, io°, 200, 300, 450, 6o°, 750, 900, 1350, 1800, 2250, 2700, or more than 2700.
A substantially linear actuating movement may include movements where a tangent of the momentary movement is angled up to 50, such as up to 2°, with respect to a perfectly linear actuating movement. However, the actuator according to the present disclosure may also be configured to provide a linear actuating movement in the first direction.
The actuator may be configured to provide the substantially linear actuating movement in the first direction in a substantially vertical plane comprised by the access member and parallel with a main surface of the access member when the access member is in a closed position and when the access member is substantially vertically oriented in the closed position. Correspondingly, the actuator may be configured to provide the substantially linear actuating movement in the first direction in a substantially horizontal plane comprised by the access member and parallel with a main surface of the access member when the access member is in a closed position and when the access member is substantially horizontally oriented in the closed position. In this manner, the actuator may be fully integrated in the access member and/or in the frame and may thereby be hidden when the access member is in the closed position. Throughout the present disclosure, the terminology substantially vertical, substantially horizontal, substantially parallel etc. is intended to embrace variants having deviations of up to 50, such as up to 2°, with respect to an ideal orientation. Of course this terminology also embraces vertical, horizontal, parallel etc. (i.e. without the preceding "substantially"). In case the frame is vertically oriented, the at least one hinge may be provided on a vertical side or a horizontal top side or bottom side of the access member. Corresponding configurations may also be employed when the frame is horizontally oriented or inclined.
The transmission mechanism may be configured to transmit the actuating movement in the first direction provided by the actuator to an opening movement of the access member and the transmission mechanism may be configured to transmit an actuating movement in a second direction, opposite to the first direction, provided by the actuator to a closing movement of the access member. Throughout the present disclosure, the opening movement and the closing movement may be a rotational opening movement and a rotational closing movement, respectively.
In case the manipulator comprises a transmission mechanism of this type, the manipulator may be referred to as an opening and closing manipulator. However, the transmission mechanism may alternatively be configured to transmit only linear actuating movements in one direction from the actuator to a rotational movement of the access member. The transmission
mechanism may also serve as an "initiator" to merely initiate a closing movement and/or an opening movement.
The transmission mechanism and the actuator may be connected between surfaces of the access member and the frame facing each other when the access member is in a closed position. These surfaces may be constituted by a vertical (hinge) side surface of a conventional door and the mating surface of the frame when the door is closed.
The transmission mechanism may comprise a hinge. That is, the hinge may be utilized to transfer forces from the actuator to the access member. In case the transmission mechanism comprises a concealed hinge, a central link of the concealed hinge may be used to transfer (e.g. linear) forces from the actuator to a rotational movement of the access member.
The actuator may be configured to provide the substantially linear actuating movement in the first direction substantially parallel with an interface plane between the access member and the frame when the access member is in a closed position. The interface plane may alternatively be referred to as a mating plane and may be constituted by a plane parallel with the vertical (hinge) side surface of a conventional door and the mating surface of the frame when the door is closed.
The transmission mechanism may comprise a pivot connection and an elastic element connected between the pivot connection and the actuator. The pivot connection may for example be constituted by a ball joint or a flexible joint. The elastic element may for example be constituted by a spring, such as a leaf spring, a rubber component or even magnets exhibiting elastic properties due to a repelling action.
The transmission mechanism may comprise a strut member having two ball joints, and the transmission mechanism may be connectable to the access member or the frame by means of a ball joint and to the actuator by means of a ball joint. In this case, the actuator may comprise a slidable rail on which the flexible joint is provided.
The transmission mechanism may comprise a further strut member having two ball joints, wherein the further strut member is connectable to the access member or the frame by means of a ball joint and to the actuator by means of a ball joint, and wherein the two strut members are pivotally coupled to each other. With this variant, the two strut members may form an X-shape when the access member is in an open position and may be substantially aligned (i.e. substantially parallel) when the access member is in a closed position. This variant may be used with two actuators, each comprising a slidable rail on which a flexible joint is provided.
One or both strut members may comprise a piston damper. The piston damper may for example be a pneumatic piston damper or a spring based piston damper.
The actuator may be configured to provide the substantially linear actuating movement in the first direction substantially perpendicular to an interface plane between the access member and the frame when the access member is in a closed position. Thus, the substantially linear actuating movement may be carried out in a main extension plane of the frame or in a main extension plane of the access member, as the case may be. The transmission mechanism may be configured to transmit the actuating movement in the first direction provided by the actuator to a rotational movement of the access member by means of an engageable structure and an engaging member configured to engage the engageable structure. The engaging member may be configured to engage the engageable structure in one or both directions of the substantially linear movement of the actuator. A spring mechanism may be used to force the access member in the opposite direction, i.e. when the engaging member is "passive". The engageable structure may be constituted by a groove and the engaging member may be constituted by a pin configured to engage the groove. The transmission mechanism may comprise a wedge member and the engageable structure or the engaging member may be provided on the wedge member. The engaging member may be permanently fixed in the engageable structure, for example by means of a mushroom shaped pin engaging a recess with flanges. However, it may also be possible to disengage the engaging member and the engageable structure, for example by retracting the wedge member further once the access member has been closed, for example such that an engaging member in the form of a pin is pulled out from an
engageable structure in the form of a recess.
The transmission mechanism may comprises a hinge having a pin member and wherein the engageable structure or the engaging member is provided on the pin member. According to one variant, the pin member comprises an engageable structure in the form of a helical groove.
The transmission mechanism may comprise a barrel hinge having a pin member, and a hinge portion axially movable with respect to the pin member in the first direction, wherein an engageable structure is provided on the pin member and an engaging member is provided on the hinge portion, or vice versa, such that an axial movement of the hinge portion in the first direction is translated into a rotation of the pin member to provide the opening or closing movement of the access member. The hinge portion may have a substantially flat appearance. Alternatively, or in addition, the hinge portion may be rotationally fixed with respect to the access member or to the frame, as the case may be.
Two further hinge portions may also be used for this variant, one hinge portion fixedly attached to the frame and one hinge portion fixedly attached to the access member. One of these to hinge portions may also be fixedly attached to the pin member and the other one of these two hinge portions may have an opening provided with an inwardly protruding engaging member (e.g. a tap) in order to engage the engageable structure.
According to a further aspect, there is provided a system comprising a frame, an access member rotatably coupled to the frame by means of at least one hinge and a manipulator according to the present disclosure. Throughout the present disclosure, the system may alternatively be referred to as a door assembly.
The system may further comprise a recess provided in the access member and/or in the frame for accommodating the transmission mechanism when the access member is in a closed position. The recess may be oriented substantially parallel with an interface plane between the access member and the frame when the access member is in a closed position.
Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the element, apparatus, component, means, step, etc." are to be interpreted openly as referring to at least one instance of the element, apparatus, component, means, step, etc., unless explicitly stated otherwise.

The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the description.
Fig. l schematically represents a perspective view of a system 10 comprising a manipulator 12, a frame 14 and an access member 16 in the form of a door leaf in an open position. The manipulator 12 comprises an actuator 18 and a transmission mechanism 20. The access member 16 is coupled to the frame 14 by means of one or several hinges (not shown). These one or more hinges may for example be constituted by barrel hinges or concealed hinges.
The actuator 18 is provided in the frame 14 and is arranged to move vertically downwards in a first direction 22 and vertically upwards in a second direction 24. The actuator 18 is accommodated in a vertical recess 26 in the frame 14. The recess 26 is oriented parallel with an interface plane between the access member 16 and the frame 14 when the access member 16 is in a closed position. In Fig. 1, the actuator 18 comprises a plate member or slidable rail. The transmission mechanism 20 in Fig. 1 comprises a strut member 28 and two ball joints 30, 32. Each of the ball joints 30, 32 allows free movement in two planes at the same time, including pivotal movements. The strut member 28 is connected to the plate member of the actuator 18 by means of the ball joint 32 and connected to a vertical side surface or hinge surface of the access member 16 by means of the ball joint 30. The transmission mechanism 20 and the actuator 18 are thus connected between surfaces of the access member 16 and the frame 14 facing each other when the access member 16 is in a closed position.
When the actuator 18 is moved downwards in the first direction 22, the strut member 28 pushes the access member 16 to rotate in an opening direction. When the actuator 18 is moved upwards in the second direction 24, the strut member 28 pulls the access member 16 to rotate in a closing direction. The opening direction and closing direction are indicated by arrows 34. In this manner, the manipulator 12 is configured to open and close the access member 16. In the closed position of the access member 16, also the strut member 28 is accommodated in the recess 26 of the frame 14.
Moreover, the actuator 18 is configured to provide a substantially linear actuating movement in the first direction 22 and the transmission
mechanism 20 is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to an opening movement of the access member 16. The actuator 18 is thus configured to provide the substantially linear actuating movement in the first direction 22 substantially parallel with an interface plane or mating plane between the access member 16 and the frame 14 when the access member 16 is in a closed position. As can be gathered from Fig. 1, the actuator 18 is configured to provide the substantially linear movement in the first direction 22 in a substantially vertical plane comprised by the access member 16 and parallel with a main surface 46a of the access member 16 when the access member 16 is in a closed position. The transmission mechanism 20 is also configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to an opening movement of the access member 16 and the transmission mechanism 20 is configured to transmit an actuating movement in the second direction 24, which is opposite to the first direction 22, provided by the actuator 18 to a closing movement of the access member 16.
The configuration in Fig. 1 may be reversed, i.e. the actuator 18 may instead be provided in the access member 16. The strut member 28 may comprise or may be constituted by a piston damper. Fig. 2 schematically represents a perspective view of a further system 10 comprising a manipulator 12, a frame 14 and an access member 16 in an open position. Mainly differences with respect to Fig. 1 will be described.
The transmission mechanism 20 in Fig. 2 comprises a further strut member 36. The further strut member 36 is attached to each of the access member 16 and the frame 14 by means of ball joints 30, 32. Moreover, the two strut members 28, 36 are pivotally coupled to each other. In the open position of the access member 16 in Fig. 2, the two strut members 28, 36 adopt an X- shape. A further actuator 18 is provided on the access member 16 and is slidable in a vertical recess 26 provided at a vertical side surface of the access member 16.
By actuating the two actuators 18 to provide substantially linear actuating movements in the first direction 22 (which is directed vertically upwards in Fig. 2), the access member 16 is opened due to the forces imparted on the transmission mechanism 20. Conversely, by actuating the two actuators 18 to provide substantially linear actuating movements in the second direction 24 (which is directed vertically downwards in Fig. 2), the access member 16 is closed due to the forces imparted on the transmission mechanism 20. In the closed position of the access member 16, the two strut members 28, 36 of the transmission mechanism 20 are aligned (made at least substantially parallel) and accommodated in the recesses 26.
Fig. 3a schematically represents a side view of a further system 10 comprising a manipulator 12, a frame 14 and an access member 16 in a closed position and Fig. 3b schematically represents a top view of the system 10 in Fig. 3a. Mainly differences with respect to Figs. 1 and 2 will be described.
The manipulator 12 in Figs. 3a and 3b comprises an actuator 18 and a transmission mechanism 20. The transmission mechanism 20 of this example comprises a pivot connection 38 and an elastic element 40 connected between the actuator 18 and the pivot connection 38. In Figs. 3a and 3b, the elastic element 40 is exemplified as a spring. The transmission mechanism 20 may alternatively comprise a linkage between the actuator and the access member 16.
As can be seen in Fig. 3b, the access member 16 is rotationally coupled to the frame 14 by means of a hinge 42. The hinge 42 illustrated in Fig. 3b is constituted by a barrel hinge 44. However, the hinge 42 in this embodiment may alternatively be implemented as a concealed hinge and may form a part of the transmission mechanism 20.
The actuator 18 is accommodated in a recess 26 in the frame 14. Figs. 3a and 3b show that the actuator 18 is configured to provide the substantially linear movement in the first direction 22 substantially perpendicular to an interface plane between the access member 16 and the frame 14 when the access member 16 is in the illustrated closed position. Thereby, the substantially linear actuating movement in the first direction 22 is carried out in a main extension plane of the frame 14. The transmission mechanism 20 in Figs. 3a and 3b is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to a rotational opening movement of the access member 16. The transmission mechanism 20 is also configured to transmit the actuating movement in the second direction 24 provided by the actuator 18 to a rotational closing movement of the access member 16. The actuator 18 is configured to provide the substantially linear actuating movement in the first direction 22 in a substantially vertical plane comprised by the access member 16 and parallel with a main surface 46a, 46b of the access member 16 when the access member 16 is in a closed position and when the access member 16 is substantially vertically oriented in the closed position.
The transmission mechanism 20 in Figs. 3a and 3b is further configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to a rotational opening movement of the access member 16 and the transmission mechanism 20 is configured to transmit an actuating movement in a second direction 24, opposite to the first direction 22, provided by the actuator 18 to a rotational closing movement of the access member 16. In addition, the transmission mechanism 20 and the actuator 18 in Figs. 3a and 3b are connected between surfaces of the access member 16 and the frame 14 facing each other when the access member 16 is in a closed position.
The configuration in Figs. 3a and 3b may be reversed, i.e. the actuator 18 may alternatively be provided in a recess 26 in the access member 16.
Fig. 3c schematically represents a top view of a further system 10 comprising a manipulator 12, a frame 14 and an access member 16 in a closed position. Mainly differences with respect to Figs. 3a and 3b will be described.
In the example of Fig. 3c, the actuator 18 is accommodated in a recess 26 in the access member 16. The actuator 18 is configured to provide the
substantially linear actuating movement in the first direction 22 substantially perpendicular to an interface plane between the access member 16 and the frame 14 when the access member 16 is in the illustrated closed position.
Thereby, the substantially linear actuating movement in the first direction 22 is carried out in a main extension plane of the access member 16.
When the actuator 18 moves in the first direction 22, it will come in contact with a side surface 47 of the frame 14. As the actuator 18 is moved further in the first direction 22, it will push against the side surface 47 and cause a rotation of the access member 16 around the hinge 42 (in the counter clockwise direction in Fig. 3c) relative to the frame 14. The side surface 47 and/or the hinge 42 may thereby be said to constitute, or be comprised by, the transmission mechanism 20. Thus, in the variant in Fig. 3c, the actuator 18 acts directly on the frame 14 (or on the access member 16 if reversed) in contrast to the remaining variants of the present disclosure where the actuator 18 acts indirectly on the frame 14 or indirectly on the access member 16 via the transmission mechanism 20. The actuator 18 in Fig. 3c may for example comprise a ball screw and a rod to contact the side surface 47 of the frame 14. The transmission mechanism 20 in Fig. 3c is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to a rotational opening movement of the access member 16. The actuator 18 is configured to provide the substantially linear actuating movement in the first direction 22 in a substantially vertical plane comprised by the access member 16 and parallel with a main surface 46a, 46b of the access member 16 when the access member 16 is in a closed position and when the access member 16 is substantially vertically oriented in the closed position.
The configuration in Figs. 3c may be reversed, i.e. the actuator 18 may alternatively be accommodated in a recess 26 in the frame 14.
Fig. 4 schematically represents a perspective view of a further manipulator 12. Mainly differences with respect to Figs, la, lb, 2 and 3 will be described. The manipulator 12 may be connected to a frame 14 and an access member 16. The manipulator 12 of Fig. 4 comprises a transmission mechanism 20 constituted by a hinge 42 in the form of a concealed hinge 48 and an actuator 18. The actuator 18 comprises a wedge member 50 movable vertically downwards in the first direction 22 and vertically upwards in the second direction 24. The wedge member 50 comprises an engageable structure 52 in the form of a groove. An engaging member 54 in the form of a pin engages the engageable structure 52 of the wedge member 50. The wedge member 50 may be accommodated in a recess 26 in the frame (or in the access member).
The engaging member 54 is in turn pivotally connected (about a vertical axis) to one of four central links 56 of the concealed hinge 48. Thus, by actuating the actuator 18 in the form of the wedge member 50 in the first direction 22, the engaging member 54 is, due to its engagement with the engageable structure 52 of the the wedge member 50, moved horizontally (to the right in Fig. 4). As a consequence, the central link 56 is pushed horizontally so that the concealed hinge 48 is opened to open an access member (not shown). Conversely, by actuating the actuator 18 in the form of the wedge member 50 in the second direction 24, the engaging member 54 is, due to its engagement with the engageable structure 52 of the the wedge member 50, moved horizontally (to the left in Fig. 4). As a consequence, the central link 56 is pulled horizontally so that the concealed hinge 48 is closed to close the access member (not shown).
Also in the embodiment in Fig. 4, a reverse configuration is possible, i.e. the actuator 18 may alternatively be provided in a frame 14. In addition, the configuration of the wedge member 50 may be reversed such that the actuator 18 comprises an engaging member 54 (e.g. a pin) and the wedge member 50 is moved horizontally due to the engagement of the engaging member 54 in the engageable structure 52 of the wedge member 50. The horizontal movement of the wedge member 50 may then be transferred to a horizontal movement of the central link 56 to open or close the hinge 42. The engaging member 54 of Fig. 4 comprises, although not shown, a mushroom shaped pin. The engageable structure 52 of the wedge member 50 in turn is constituted by a recess with flanges. This is one possible realization of a manipulator 12 that can both open and close an access member 16.
It is possible to provide an opening in the extension direction of the engageable structure 52 formed as a recess. In this manner, when the hinge 42 has been closed (such that an access member 16 is closed), the wedge member 50 may be further actuated in the second direction 24 such that the engaging member 54 drops out from the opening of the engageable structure 52. After this, an access member 16 may be manipulated entirely manually, i.e. without the need to actuate the actuator 18.
Thus, also in Fig. 4, the actuator 18 is configured to provide a substantially linear actuating movement in a first direction 22, and the transmission mechanism 20 is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to an opening movement of the access member 16. Furthermore, the actuator 18 is configured to provide the substantially linear actuating movement in the first direction 22 in a substantially vertical plane comprised by the access member 16 and parallel with a main surface 46a, 46b of the access member 16 when the access member 16 is in a closed position and when the access member 16 is substantially vertically oriented in the closed position.
The transmission mechanism 20 in Fig. 4 is also configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to an opening movement of the access member 16 and the transmission
mechanism 20 is configured to transmit an actuating movement in the second direction 24, opposite to the first direction 22, provided by the actuator 18 to a closing movement of the access member 16. In addition, the transmission mechanism 20 and the actuator 18 are connected between surfaces of the access member 16 and the frame 14 facing each other when the access member 16 is in a closed position. The actuator 18 is further configured to provide the substantially linear actuating movement in the first direction 22 substantially parallel with an interface plane between the access member 16 and the frame 14 when the access member 16 is in a closed position.
Fig. 5 schematically represents a perspective view of a further manipulator 12. Mainly differences with respect to Figs, la, lb, 2, 3 and 4 will be described.
The manipulator 12 in Fig. 5 comprises a hinge 42 in the form of a barrel hinge 44 having a pin member 58. The barrel hinge 44 comprises a first hinge portion 60, a second hinge portion 62 and a third hinge portion 64. The first hinge portion 60 and the third hinge portion 64 may be connected to a frame (not shown) and the second hinge portion 62 may be connected to an access member (not shown). The third hinge portion 64 may be fixedly attached to the frame and the second hinge portion 62 may be fixedly attached to the access member. The pin member 58 is received in an opening in the third hinge portion 64 and is allowed to rotate freely therein about a hinge axis 66 in the directions indicated by arrows 34. In Fig. 5, the first hinge portion 60 constitutes a part of the actuator 18 and is vertically guidable in a slot (not shown) of the frame. The pin member 58 further comprises an engageable structure 52 in the form of a helical groove. The pin member 58 is received in an opening of the first hinge portion 60. One or several engaging members (not shown) in the form of one or more pins protrude radially inwardly from the opening of the first hinge portion 60 to engage the engageable structure 52. Due to this engagement, as the actuator 18 and the first hinge portion 60 are moved vertically downwards along the first direction 22, the pin member 58 is forced to rotate (to the right in Fig. 5). This causes the second hinge portion 62 to rotate and consequently also an access member 16 fixed thereto to rotate.
Thus, also in Fig. 5, the transmission mechanism 20 is configured to transmit an actuating movement in the first direction 22 provided by the actuator 18 to a rotational opening movement of the access member 16 by means of an engageable structure 52 and an engaging member configured to engage the engageable structure 52. Conversely, the transmission mechanism 20 is configured to transmit an actuating movement in the second direction 24 provided by the actuator 18 to a rotational closing movement of the access member 16 by means of the engageable structure 52 and the engaging member.
It should further be noted that in Fig. 5, the actuator 18 is configured to provide a substantially linear actuating movement in a first direction 22 and the transmission mechanism 20 is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to an opening movement of the access member 16. Moreover, the actuator 18 is configured to provide the substantially linear actuating movement in the first direction 22 in a substantially vertical plane comprised by the access member 16 and parallel with a main surface 46a, 46b of the access member 16 when the access member 16 is in a closed position and when the access member 16 is substantially vertically oriented in the closed position. l8
In addition, the transmission mechanism 20 in Fig. 5 is configured to transmit the actuating movement in the first direction 22 provided by the actuator 18 to a rotational opening movement of the access member 16 and the transmission mechanism 20 is configured to transmit an actuating movement in the second direction 24, which is opposite to the first direction 22, provided by the actuator 18 to a rotational closing movement of the access member 16. The transmission mechanism 20 and the actuator 18 may further be connected between surfaces of the access member 16 and the frame 14 facing each other when the access member 16 is in a closed position. Clearly, the transmission mechanism 20 in Fig. 5 also comprises a hinge 42. The actuator 18 is also configured to provide the substantially linear actuating movement in the first direction 22 substantially parallel with an interface plane between the access member 16 and the frame 14 when the access member 16 is in a closed position. While the present disclosure has been described with reference to exemplary embodiments, it will be appreciated that the present invention is not limited to what has been described above. For example, it will be appreciated that the dimensions of the parts may be varied as needed. Accordingly, it is intended that the present invention may be limited only by the scope of the claims appended hereto.
