Description:
Catching device for catching and retaining a wing

BACKGROUND

The invention relates to a catching device for catching and retaining a wing, in particular the wing of a door or window.

A known catching device for catching and retaining a wing is shown in figure 8. Said known catching device is arranged to be mounted to a wall and comprises a catching body and a step in the catching body followed by a recess for receiving and retaining a door handle of the wing in the open position of the wing.

SUMMARY OF THE INVENTION

A disadvantage of the known catching device is that the recess is considerably larger than the door handle, such that the door handle tends to clatter within the recess when retained. Potentially, the door could even be unintentionally released from the known catching device due to the clattering, which could result in damage to the door when it slams shut and/or the owner being locked out of the house.

It is an object of the present invention to provide a catching device for catching and retaining a wing, wherein the wing can be retained more reliably.

According to a first aspect, the present invention provides a catching device for catching and retaining a wing, wherein the wing is movable in an opening direction from a closed position to an open position, wherein, in the open position, the wing is in close proximity to a wall, wherein an operating assembly is provided on said wing, wherein the operating assembly comprises a first operating member for operating the operating assembly between a locking state and an unlocking state, wherein the catching device comprises a catching body defining a mounting plane for mounting the catching device to the wall in a catching direction perpendicular or substantially perpendicular to the mounting plane, wherein the catching device comprises a recess extending through the catching body in a recess direction perpendicular to the catching direction from a first side of the catching body to a second side of the catching body opposite to the first side, wherein the recess is open in a receiving direction perpendicular to the catching direction and the recess direction for receiving the first operating member, wherein the recess has a central area between the first side and the second side, wherein the recess is bounded in the catching direction by a first retaining surface and a second retaining surface opposite to the first retaining surface for retaining the first operating member in the catching direction, wherein the recess has a first width, a second width and a third width in the catching direction between the first retaining surface and the second retaining surface at the first side, the second side and the central area, respectively, wherein the third width is smaller than the first width and the second width and wherein the recess tapers from the first width and the second width to the third width at the central area.

The catching device according to the present invention provides the advantage that a tolerance between the first operating member and the recess can be reduced over a broad angular range. Hence the first operating member can be retained more tightly by the recess and clattering and/or unpredicted movements can be prevented. As a result, unintended release of the first operating member can be prevented and, thus, the first operating member can be retained more reliably.

In an embodiment the recess gradually tapers from the first width and the second width to the third width at the central area. As a result, a larger area of the first retaining wall and the second retaining wall can be in contact or abutment with the first operating member, especially at larger angles between the two. The first operating member can thus be retained even more tightly and reliably .

In a further embodiment the recess linearly tapers from the first width and the second width to the third width at the central area. This can be particularly useful when the first operating member is substantially prismatic. Hence, the linearly tapering retaining surface can be in contact with a larger portion of the first operating member. Moreover, without any abrupt changes in direction, the first operating member can be retained more reliably .

In a further embodiment thereof the first retaining surface extends from the first side towards the central area at a first tapering angle between twenty and forty degrees with respect to the mounting plane, preferably between twenty-five and thirty-five degrees with respect to the mounting plane. In a further embodiment thereof the first retaining surface extends from the second side towards the central area at a second tapering angle between twenty and forty degrees with respect to the mounting plane, preferably between twenty-five and thirty- five degrees with respect to the mounting plane. In an even further embodiment the second retaining surface extends on either side of the central area under oppositely directed tapering angles with respect to the tapering angles of the first retaining surface. Hence, the catching device can retain the first operating member in different wall/frame configurations resulting in the wing being at different (or opposite) angles with respect to the wall in its maximum open position. In a further embodiment the recess is concave about the recess direction. Hence, the catching device can more tightly retain a first operating member having the same or a slightly different shape and/or size than the recess .

In a further embodiment the catching device has an intermediate plane that forms a center plane for the recess. In a further embodiment thereof the intermediate plane forms a plane of symmetry for the recess. As a result, the catching device can receive and retain the first operating member from both directions in substantially the same way.

In a further embodiment the catching body has a terminal end opposite to the mounting plane, wherein the terminal end is arranged to contact the wing when the catching device has failed to catch the first operating member in the recess. The terminal end can prevent the first operating member from slamming into the wall by catching the wing, in particular when the first operating member skips the recess.

In a further embodiment thereof, the catching body is tapered from the recess towards the terminal end and comprises an inclined run-on surface for urging the first operating member from the locking state towards the unlocking state when moving in the opening direction. Hence the first operating member can be automatically urged towards the unlocking state and past the first retaining wall when moving the wing in the opening direction. This can be particularly advantageous when the first operating member is biased towards the locking state, such that the first operating member can automatically be urged into the recess when it has moved past the first retaining wall.

In a further embodiment the catching body comprises a fastener hole extending through the catching body in the catching direction for receiving a fastener to mount the catching device to the wall. With a fastener, the catching device can be securely attached to the wall. In a further embodiment thereof the fastener hole ends with a sunk hole at the terminal end. The sunk hole can prevent the fastener from protruding past the catching body. As a result, damage to the wing can be prevented. Moreover, it can be prevented that the fastener forms an obstruction in the run-on surface.

According to a second aspect, the invention provides a set comprising the catching device according to the present invention and a first operating member. The catching device and the first operating member can be designed for optimal cooperation and can be sold together as a set to make sure that - in use - they work together optimally to ensure proper and reliable engagement of the first operating member by the catching device.

In an embodiment thereof the first operating member is an elongate door handle. The elongate door handle can be engaged relatively easily in the recess of the catching member. Moreover, the elongate door handle can provide a larger contact area in cooperation with the catching device. Hence, the elongate door handle can be more tightly retained by the catching device.

In a further embodiment thereof the first operating member has a cross-sectional contour that at least partially corresponds or substantially corresponds to a cross-sectional contour of the recess. Having a corresponding or substantially corresponding cross- sectional contour can make the first operating member fit more snugly in the recess. Hence, the first operating member can be retained more reliably.

In a further embodiment the door handle extends in a lever direction and has an at least partially circular cross section perpendicular to said lever direction and having a diameter, wherein the third width of the catching device is equal or substantially equal to the diameter of the first operating member. Having a diameter equal or substantially equal to the third with of the catching member can make the first operating member fit more snugly in the recess. Hence, the first operating member can be retained more reliably.

In an even further embodiment the catching device is arranged for receiving and retaining said first operating member with the lever direction extending at all angles with respect to the mounting plane within a range of zero to twenty degrees with respect to the mounting plane, preferably within a range of zero to forty degrees with respect to the mounting plane. Thus, the catching device can retain a wing over a broad angular range.

The various aspects and features described and shown in the specification can be applied, individually, wherever possible. These individual aspects, in particular the aspects and features described in the attached dependent claims, can be made subject of divisional patent applications .

DETAILED DESCRIPTION OF THE INVENTION

Figures 1-3 show a catching device 1 according to an exemplary embodiment of the invention for catching and retaining a wing 8, in particular a wing of a door or a window, with respect to different wall/frame configurations, as shown. In particular, figure 1 shows a first wall 9 with a wing frame 91 that holds the wing 8 in a first configuration relative to the first wall 9. Figure 2 shows a second wall 109 with a wing frame 191 that holds the wing 8 in a second configuration relative to the second wall 109. Finally, figure 3 shows a third wall 209 with a wing frame 291 that holds the wing 8 in a third configuration relative to the third wall 209.

The wing 8 is hinged to the wing frame 91, 191, 291 to be movable between a closed position and an open position, wherein only the open position has been shown. An operating assembly 7 is provided on said wing 8 for locking and unlocking the wing 8 with respect to a wing frame 91, 191, 291. Figures 1-3 show the wing 8 in a maximum open position in which the wing 8 is in close proximity to the wall 9, 109, 209.

The catching device 1 according to the invention is mounted to the wall 9, 109, 209 directly opposite to the operating assembly 7 for receiving and retaining the wing 8 by engaging the operating assembly 7.

The wing 8 comprises a planar or plate like wing body 80 extending in a wing direction B. The wing body 80 has a first wing side 81 and second wing side 82 opposite to the first wing side 81. The operating assembly 7 comprises a first operating member 71 at the first wing side 81 for operating the operating assembly 7 between a locking state and an unlocking state. Conveniently, the operating assembly 7 further comprises a second operating member 72 at the second wing side 82 operably connected to the first operating member 71 for simultaneously operating and/or moving in unison with the first operating member 71 to unlock the wing 8 with respect to the wing frame 91, 191, 291.

In this embodiment, the first operating member 71 is a handle, in particular a handle that acts as a lever to unlock the wing 8 relative to the wing frame 91, 191, 291. The first operating member 71 extends in a lever direction C parallel or substantially parallel to the first wing side 81 and having a diameter D perpendicular to said lever direction C. The first operating member 71 is pivotable in an unlocking direction about a rotation axis perpendicular or substantially perpendicular to the first wing side 81 between the locking state, as shown in figure 7A, and the unlocking state, as shown in figure 7B. Preferably, the first operating member 71 is biased to return into the locking state, as shown in figure 6C.

The second operating member 72 can be a handle similar to first operating member 71, yet mirrored with respect the wing 8 on the other wing side 82. Alternatively, the second operating member 72 can be a knob or any other suitable operating member that is able to be coupled to and move in unison with the first operating member 71.

As shown in figure 1 the catching device 1 is mounted in a catching direction X normal to a mounting plane PI to the first wall 9 in a position directly opposite to the first operating member 71 when the wing 8 is in the maximum open position relative to the first wall 9. In this exemplary embodiment, the first wall 9 consists of two wall parts that extend perpendicularly to each other. One of the wall parts holds the wing frame 91, while the other is provided with the catching device 1. The wing 8 is movable in an opening direction A between the closed position at the wing frame 91 and the maximum open position in which the wing 8 is in close proximity to the first wall 9, as shown in figure 1. In this particular wall/frame configuration, the wing direction B in the maximum open position of the wing 8 is parallel or substantially parallel to the mounting plane PI.

In figure 2 the catching device 1 is alternatively mounted in the catching direction X normal to the mounting plane Pi to a second wall 109. The second wall 109 differs from the previously discussed first wall 9 in that, in the resulting wall/frame configuration, the hinging side of the wing 8 has a different distance to the wall part that holds the catching device 1. Consequently, the wing 8 arrives in the maximum position, as shown in figure 2, with the wing direction B at a different angle, in particular a first, non-parallel and/or oblique angle HI to the mounting plane Pi.

In figure 3 the catching device 1 is alternatively mounted in the catching direction X normal to the mounting plane Pi to a third wall 209. The third wall 209 differs from the previously discussed first wall 9 and second wall 109 in that, in the resulting wall/frame configuration, the hinging side of the wing 8 has a different distance to the wall part that holds the catching device 1. In particular, the hinging side of the wing 8 is closer to the wall part that holds the catching device 1 with respect to the situation as shown in either figure 1 or figure 2. Consequently, the wing 8 arrives in the maximum position, as shown in figure 3, with the wing direction B at yet another different angle, in particular a second, non-parallel and/or oblique angle H2 to the mounting plane Pi opposite to the non-parallel and/or oblique angle as shown in figure 2.

As best seen in figures 4 and 5, the catching device 1 comprises a catching body 10 that defines the mounting plane PI for mounting the catching body 10 to the wall 9, 109, 209, as shown in figure 6A. In this exemplary embodiment, the catching body 10 has a flat face that defines the mounting plane PI. Alternatively, the mounting plane PI may be defined by a number of ribs or other structural elements of the catching body 10. The catching body 10 extends from the mounting plane PI parallel to the catching direction X towards the first operating member 71, as shown in figures 6A. The catching body 10 further comprises a recess 11 that extends through the catching body 10 in a recess direction Y perpendicular to the catching direction X from a first side 12 of the catching body 10 to a second side 13 of the catching body 10 opposite to the first side 12. The recess 11 is open in a receiving direction Z perpendicular to the catching direction X and the recess direction Y for receiving the first operating member 71, as shown in figure 6C. The recess 11 is defined, limited and/or bounded in the catching direction X by a first retaining surface 14 and a second retaining surface 15 opposite to the first retaining surface 14 for retaining the operating assembly 7 in the opening direction A when in the locking state. The catching device 1 has an intermediate plane P2 perpendicular to the recess direction Y in a central area CA of the recess 11 between the first side 12 and the second side 13. Preferably, the intermediate plane P2 forms a plane of symmetry for the recess 11.

The first retaining surface 14 and the second retaining surface 15 are spaced apart in the catching direction X by a first width W1 at the first side 12 of the catching body 10, by a second width W2 at the second side 13 of the catching body 10 and by a third width W3 at the intermediate plane P2. The first width Wl and the second width W2 are larger than the third width W3. In this exemplary embodiment, the recess 11 tapers from the first side 12 and the second side 13 towards the central area CA. In particular, the recess 11 gradually tapers from the first side 12 and the second side 13 towards the central area CA. More specifically, the recess linearly tapers from the first side 12 and the second side 13 towards the central area CA.

In this example, the first retaining surface 14 extends from the first side 12 towards the central area CA at a tapering angle T between twenty and forty degrees with respect to the mounting plane PI. More preferably, the tapering angle T is between twenty-five and thirty-five degrees with respect to the mounting plane Pi. The second retaining surface 15 extends under oppositely directed tapering angles with respect to the first retaining surface 14 on either side of the central area CA.

As is best shown in figures 6A-6C, the catching body 10 comprises a free, distal or terminal end 16 opposite to the mounting plane PI. Said terminal end 16 is arranged to contact or abut the wing 8 in the event that the first operating member 71 skips the recess 11, i.e. when the catching device 1 fails to catch the first operating member 71. The catching body 10 is tapered from the recess 11 towards the terminal end 16. As a result, the catching body 10 comprises an inclined run-on surface 17 at or near the terminal end 16 to force, push or urge the first operating member 71 from the locking state, as shown in figure 6A, towards the unlocking state, as shown in figure 6B, when the wing 8 of figure 1 is moved in the opening direction A. Consequently, the first operating member 71 is able to move over the first retaining surface 14 into the recess 11, as shown in figure 6C.

The catching device 1 further comprises a fastener hole 16 for receiving a fastener 6 for mounting the catching device 1 to the wall 9, 109, 209, as shown in figure 5. The fastener hole 18 extends in the catching direction X through the catching body 10 at a distance spaced apart from the recess 11 in the receiving direction Z. Preferably, the fastener hole 18 ends with a sunk hole 19 at the terminal end 16 such that the fastener 6 can be received in a position below the surface of the catching body 10, in particular below and/or free from the terminal end 16 and/or the run-on surface 17.

Figures 6A-6C show the catching device 1 and the first operating member 71 during exemplary steps of a method for catching the first operating member 71.

In particular, figure 6A shows the situation in which the first operating member 71 has approached the catching device 1 as a result of the wing 8, as shown in figure 1, approaching the maximum open position. The first operating member 71 now abuts the terminal end 16, in particular the inclined run-on surface 17 at or near said terminal end 16. Consequently, the catching device 1 starts or is already urging the first operating member 71 from the locking state towards the unlocking state.

Figure 6B shows the situation in which the first operating member 71 has continued to move along the inclined run-on surface 17 and the catching device 1 has continued to urge the first operating member 71 further from the locking state towards the unlocking state. Hence, the first operating member 71 is now almost in a position in which it is able to pass the first retaining surface 14.

Figure 6C shows the situation in which the first operating member 71 has been received in the receiving direction Z into the recess 11. As shown in figure 4, the recess 11 is concave about the recess direction Y, such that catching device 1 may receive and retain the first operating member 71 having a geometry that snugly fits in said concave recess 11 or an alternative operating member with a different geometry, e.g. a diameter differing from the diameter D of the first operating member 71. As previously discussed, the first operating member 71 may be moved into the recess 11 manually or as a result of a biasing force exerted by the operating assembly 7, as shown in figure 1, on the first operating member 71 in the receiving direction Z. Figures 7A-7C show the catching device 1 and the first operating member 71 during exemplary steps of a method for releasing the first operating member 71.

In particular, figure 7A shows the situation according to figure 6C, in which the first operation member 71 has been received into and is positioned within the recess 11. The first operating member 71 is retained in the catching direction X by the first surface 14 and the second surface 15. The first operating member 71 may be in the locking state or in a position close to the locking state and is movable towards the unlocking state in a direction opposite to the receiving direction Z.

Figure 7B shows the situation in which the first operating member 71 has been released from the catching device 1 and has been operated from the previously shown position towards the unlocking state. In this position, the first operating member 71 has been moved past the first retaining surface 12 in the direction opposite to the receiving direction Z.

Figure 7C shows the situation in which the first operating member 71 has been moved past the first retaining surface 14 and towards the closed position of the wing 8 in a closing direction opposite to the opening direction A whilst being kept in the unlocking state or a position between the unlocking state and the locking state.

The catching device 1 according to the present invention has the particular advantage that, in the situation as shown in figure 6C, when the first operating member 71 has been received in the recess 11, the catching device 1 can retain the wing 8, as shown in figures 1-3, and in particular the first operating member 71, more reliably. More specifically, the catching device 1 is able to receive and retain the first operating member 71 in the different wall/frame configurations as shown in figures 1- 3.

As shown in figure 1, when the wing direction B is parallel or substantially parallel to the mounting plane PI, the first retaining surface 14 and the second retaining surface 15 are arranged for closely approaching and/or contacting the first operating member 71 from both sides in the catching direction X at the central area CA and/or the intermediate plane P2.

As shown in figure 2, when the wing direction B is at the first oblique angle Hi with respect to the mounting plane PI, the first retaining surface 14 and the second retaining surface 15 are arranged for closely approaching and/or contacting the first operating member 71 from both sides in the catching direction X at the central area CA and/or the intermediate plane P2. Meanwhile, as the first width W1 and the second width W2 are larger than the third width W3, the recess 11 allows for the first operating member 71 to extend in the lever direction C obliquely through the recess 11 at said first oblique angle HI with respect to the mounting plane PI. More in particular, it can be observed in figure 2 that the first operating member 71 extends in the lever direction C, such that the first operating member 71 approaches an orientation that is parallel to or substantially parallel to a part of the first retaining surface 14 and a part the second retaining surface 15 extending from the central area CA and/or the intermediate plane P2 towards the first side 12 and the second side 13, respectively.

As shown in figure 3, also when the wing direction B is at the second oblique angle H2 with respect to the mounting plane PI, the first retaining surface 14 and the second retaining surface 15 are arranged for closely approaching and/or contacting the first operating member 71 from both sides in the catching direction X at the central area CA and/or the intermediate plane P2. In particular, the recess 11 further allows for the first operating member 71 to extend in the lever direction C obliquely through the recess 11 at said second oblique angle H2 with respect to the mounting plane PI. More in particular, it can be observed in figure 3 that the first operating member 71 extends in the lever direction C, such that the first operating member 71 approaches an orientation that is parallel to or substantially parallel to a part of the first retaining surface 14 and a part of the second retaining surface 15 extending from the central area CA and/or the intermediate plane P2 towards the second side 13 or the first side 12, respectively.

Preferably, the first operating member 71 and the catching device 1 are sold as a set, thereby allowing the catching device 1 and the first operating member 71 to be dimensioned such, that the third width W3 of the recess 11 corresponds or substantially corresponds to the diameter D of the first operating member 71. In particular, the catching device 1 and the first operating member 71 may be designed such, that at least the part of a cross-sectional contour of the outer circumference of the first operating member 71 that in use faces the recess 11 corresponds to a cross-sectional contour of the recess 11.

The particular advantage of the catching device 1 according to the present invention is that the first operating member 71 is more firmly retained by the first retaining surface 14 and the second retaining surface 15 when retained within the recess 11. In other words, tolerance between the catching device 1 and the first operating member 71 may be reduced. Hence, clattering and/or unpredictable movements of the first operating member 71 within the recess 11 may be prevented. As a result, accidental release of the first operating member 71 from the recess 11 may be prevented. In other words, the first operating member is more reliably engaged by the first retaining surface 14 and the second retaining surface 15 when retained within the recess 11. More particular, the first retaining member 71 is more firmly retained by the first retaining surface 14 and the second retaining surface 15 when the first operating member 71 extends in the lever direction C within an angular range with respect to the mounting plane between the first oblique angle HI and the second oblique angle H2.

It is to be understood that the above description is included to illustrate the operation of the preferred embodiments and is not meant to limit the scope of the invention. From the above discussion, many variations will be apparent to one skilled in the art that would yet be encompassed by the scope of the present invention.
