Description

Technical Field

[0001] The invention relates to a swing handle arrangement with a locking function. The swing handle arrangement is usually used for various cabinet doors or hatches. Prior art

[0002] In various cabinet doors or hatches, a swing handle is often used to open the door or hatch. The swing handle can also be used on ordinary doors. In the closed position of the door or hatch, the swing handle rests against the frame of the swing handle arrangement. The swing handle is therefore not exposed for rotation. In order to open the door or hatch, the swing handle is removed from the frame, whereby the swing handle can be rotated to open the door or hatch. Therefore, in this specification, a swing handle refers to this type of swing handle. The swing handle arrangement can also include a locking function. In this case, it is not possible to remove the swing handle from the frame and / or to open the door or hatch with the swing handle.

[0003] EP 3628802 proposes a prior art swing handle arrangement with a locking function. In this arrangement, an electric motor is used to release the latch from its latched position, whereby the swing handle can be removed from the frame of the arrangement. The arrangement also includes a locking element for preventing the spindle from rotating. The same electric motor also controls the latch.

[0004] The solutions of the prior art are feasible in themselves, although their functionality may involve problems. For example, when the swing handle is against the frame on which the swing handle is arranged, the door or hatch is always locked, which may be unnecessary, for example, during the day. Summary of the invention

[0005] The object of the invention is to provide an alternative embodiment with respect to the embodiments of the prior art. This is achieved in the manner presented in the independent claim. The dependent claims describe various embodiments of the invention.

[0006] The swing handle arrangement according to the invention comprises a locking function. The arrangement comprises a swing handle 1, a frame 2 and a spindle arrangement 3. The swing handle is pivotably connected to the spindle arrangement, and the spindle arrangement is pivotably connected to the frame. The swing handle arrangement further comprises an electric actuator 4, an axis arrangement 5 for the electric actuator and a latch 6 arranged in the frame 2. The swing handle further comprises a latch surface 7. The latch 6 is arranged to abut against the latch surface of the swing handle when the swing handle is in its locking position. The latch 6 and the latch surface 7 are therefore arranged to constitute a locking of the swing handle arrangement, which can be released by the electric actuator 4 via the axis arrangement 5 for the electric actuator.

[0007] The swing handle arrangement further comprises a second shaft 8 with a cam 9 and in which the latch is provided with a recess 10. In the locked position of the swing handle arrangement, the cam 9 is located in the recess, preventing a linear movement of the latch away from the latching surface 7 of the swing handle. By turning the second shaft 8 so that the cam 9 moves out of the recess 10, the lock can be unlocked by the electric actuator 4 via the shaft arrangement 5 for the electric actuator.

[0023] Figure 1 An example of a swing handle arrangement including a locking function according to the invention is shown. The arrangement comprises a swing handle 1, a frame 2 and a spindle arrangement 3. The spindle arrangement is shown in FIG. Figure 2 As shown. Swing handles are arranged for doors and hatches. In many cases, swing handles are used for doors or hatches 27 of various cabinets. Figure 1 A portion of a door or hatch 27 is shown. Figure 1 In the embodiment, the swing handle is placed against the frame 2 in which the swing handle is arranged. In order to open the door or hatch, the swing handle is rotated out of the frame, whereby the swing handle can be turned to open the door or hatch. Usually, the swing handle has a design that facilitates the swing handle to be turned out. In the present embodiment, the swing handle extends slightly beyond the lower edge of the frame at the lower end of the frame 2, such as Figure 2 shown.

[0024] The swing handle is pivotably connected to the spindle arrangement 3, and the spindle arrangement is pivotably connected to the frame 2. Figure 2 Attachment to the spindle arrangement 3 can be achieved, for example, by means of a fastening pin 28, whereby the fastening pin constitutes a pivot axis and the swing handle 1 can be swung out of the frame and back into the frame relative to the pivot axis. The spindle arrangement 3 comprises a spindle 3A communicating with the opposite side of the door or hatch. The spindle may be provided with a latching element for keeping the door or hatch closed.

[0025] The swing handle arrangement further comprises an electric actuator 4 arranged in the frame 2, a shaft arrangement 5 for the electric actuator and a latch 6. The swing handle further comprises a latching surface 7. The latch 6 is arranged to abut against the latching surface of the swing handle when the swing handle is in its locked position. The latch 6 and the latching surface 7 are thus arranged to constitute a locking of the swing handle arrangement, which can be released by the electric actuator 4 via the shaft arrangement 5 for the electric actuator.

[0026] The swing handle arrangement further comprises a second shaft 8 having a cam 9, and the latch comprises a groove 10. In the locked position of the swing handle arrangement, the cam 9 is located in the groove, preventing linear movement of the latch away from the latch surface 7 of the swing handle. This situation is as Figure 2 By rotating the second shaft 8 so that the cam 9 moves out of the groove 10 , the lock can be unlocked by the electric actuator 4 via the shaft arrangement 5 for the electric actuator.

[0027] It is also possible to provide an embodiment of the invention which comprises a lock cylinder 23 in addition to the electric actuator 4. Thus, the lock can be unlocked by the electric actuator as well as the lock cylinder. The lock cylinder can be operated by a key, electrically or in both ways.

[0028] Figure 3The components of the invention are shown in more detail in an exploded view. The latching surface 7 of the swing handle 1 is realized on a projection 7A. The frame 2 comprises various structures which are not explained in more detail in this specification as they are not necessary for describing the invention. Depending on the application, the frame and its structures can be realized in various ways. Figure 3 An example is shown where the frame structure is a plate 2A. This plate is placed between the latch 6 and the second shaft 8 and it is provided with the shapes and through holes required for fastening, for the locking element 14 and for the shape of the second shaft.

[0029] Figure 4 and 5 It is shown how the swing handle arrangement is unlocked with the electric actuator 4 . Figure 6 and 7 It is shown how to unlock the swing handle arrangement using the lock cylinder 23, 23C. As shown, the swing handle arrangement includes a spring arrangement 11 for pushing the latch 6 in the opposite direction to the above-mentioned linear movement for holding the latch against the latch surface 7 of the swing handle arrangement in the locked position of the swing handle. In this context, linear movement is described as movement of the latch away from the latch surface of the swing handle, although it is clear that its movement in the opposite direction is also linear.

[0030] The tip portion 12 of the latch comprises inclined surfaces 12A, 12B for linearly moving the latch away from and towards the frame 2 by turning the swing handle 1. Thus, the inclined surfaces are inclined relative to the longitudinal axis of the latch and the direction of the linear movement of the latch. Moreover, the latch surface 7 of the swing handle is correspondingly inclined. Thus, when the swing handle is lifted away from the frame 2, the inclined surfaces 7, 12A guide the latch 6 to move against the spring arrangement 11. In this context, the spring arrangement comprises two springs, but the number of springs may also be different. When the swing handle 1 moves backwards towards the frame 2 to connect thereto, the protrusion 7A presses the inclined surface 12B, whereby the latch 6 moves towards the spring arrangement 11. The latch is movable only when the cam 9 of the second shaft is not in the groove 10 of the latch.

[0031] The latch may include a protrusion 13 located on one side of the groove 10, ie, on the side of the groove close to the tip portion 12 of the latch. Figure 8 The projection 13 is shown in more detail in a cross-sectional view of the latch 6 . Figure 8 The plate 2A is shown provided with an opening 2C for the cam 9. If the locking arrangement is in any way tampered with to remove the cam 9 from the groove 10, the projection 13 tends to prevent the cam 9 from becoming disengaged from the groove.

[0032] The swing handle arrangement may further comprise a locking element 14 for preventing a rotation of the second shaft 8 in its blocking position. Fig. 9 and 10The operation of the locking element 14 is illustrated. Figures 11 to 13 The operation of the locking element is also shown in a cross-sectional view.The second shaft has a rotation barrier surface 15 and the locking element 14 comprises a counter surface arrangement 16 which is arranged to abut against the rotation barrier surface in the blocking position of the locking element. Fig. 9 In the embodiment, the second shaft 8 is in the blocking position; that is, the cam 9 is located in the groove 10 of the latch ( Fig. 9 (not shown). Fig. 9 In the embodiment of the present invention, the locking element 14 is not in the blocking position. Therefore, the swing handle arrangement further comprises a spring 17 for urging the locking element 14 towards the blocking position. The locking element 14 further comprises a guide surface 18 for removing the locking element 14 from the blocking position when the swing handle 1 is rotated into its locking position. Therefore, the projection 7A of the swing handle presses against the guide surface 18 and the locking element 14 moves to the locking position. Fig. 9 Position shown. Fig.11 and 12 This position of the locking element is also shown.

[0033] Fig.10 A situation is shown in which the second shaft 8 has been rotated by the electric actuator (or lock cylinder) to a position in which the cam 9 is no longer located in the groove 10 of the latch 6. As a result, the swing handle arrangement is no longer locked, but the swing handle can be lifted away from the frame 2. After the swing handle 1 has been lifted from the frame to open the door or hatch, the spring 17 pushes the locking element 14 towards the second shaft 8, wherein the opposing surface arrangement 16 of the locking element 14 abuts the rotation barrier surface 15, thereby preventing the second shaft 8 from rotating. As a result, the cam 9 cannot be rotated into a blocking position in which the cam would be accommodated in the groove 10 of the latch 6. When the swing handle 1 is pressed back against the frame 2, the projection 7A of the swing handle compresses the locking element away from the blocking position via the guide surface 18, so that the second shaft 8 can rotate so that the cam 9 will prevent the movement of the latch, i.e. move to the position in which the second shaft 8 is located. Fig. 9 The swing handle arrangement is thus locked. The figures show that the proposed embodiment comprises a second spring 22 for turning the second shaft 8 towards a position in which the cam 9 is located in the recess 10 of the latch.

[0034] exist Fig.11 In the embodiment, the swing handle arrangement is locked, wherein the swing handle 1 is in connection with the frame 2 and its projection 7A is compressed against the guide surface 18. Figures 11 to 13 ) is in a position where the cam 9 is located in the groove 10 of the latch 6. Fig.12In the embodiment, the second shaft is rotated by the electric actuator 4 to a position where the cam 9 is not located in the groove 10. Therefore, the rotation barrier surface 15 of the second shaft, which in this embodiment comprises two surfaces, is in a position where the opposing surface arrangement 16 of the locking element 14 can move against the rotation barrier surface 15. Fig.12 In the case of the swing handle 1, it has not yet been lifted, so it holds the locking element out of its blocking position.

[0035] Since the spring arrangement 11 pushes the latch towards the projection 7A and the locking surface 7, the latch 6 keeps the swing handle 1 connected to the frame 2. Thus, although the arrangement is unlocked, the swing handle 1 remains connected to the frame 2. This is advantageous, for example, when locking is not required during the day. In order to remove the swing handle from the frame, the user has to pull on the swing handle with sufficient force. This has the advantage that the swing handle arrangement can be arranged more freely in different positions on the door or hatch, without the swing handle spontaneously turning away from the frame (for example, when installed in a horizontal plane or relative to the frame). Figure 1 (shown mounted upside down).

[0036] exist Fig.13 In the embodiment shown in FIG. 1 , the swing handle 1 has been lifted and the locking element 14 has been moved towards the second shaft 8 by the spring 17. As a result, the rotation barrier surface 15 of the shaft abuts against the counter surface arrangement 16. In this position, the second shaft cannot be rotated and the cam 9 cannot be rotated into the recess 10 of the latch. This prevents the latch from locking in its blocking position, whereby the swing handle cannot be rotated back to the frame.

[0037] In the embodiment shown in the figures, the rotation barrier surface 15 comprises two surfaces, and the second shaft 8 has two recesses 19 on opposite sides, the bottoms of which form the two surfaces. The opposing surface arrangement 16 comprises a groove 20, the sides of which abut against the rotation barrier surface 15 in the blocking position of the locking element 14. Therefore, in this embodiment, the sides of the groove 20 constitute the opposing surfaces of the opposing surface arrangement 16.

[0038] In the second embodiment of the locking element 14 and its implementation, the second shaft 8 has a hole, one or more side surfaces of which constitute the rotation barrier surface 15, and the counter surface arrangement 16 comprises a projection, the side of which abuts against the rotation barrier surface 15 in the blocking position of the locking element 14.

[0039] The locking element 14 comprises a projection 21, the end face of which is the guide surface 18. The projection 21 may be, for example, a pin or a plate-like projection.

[0040] Figure 6The arrangement is shown locked; that is, the cam 9 of the second shaft is located in the groove 10 of the latch. As mentioned above, the swing handle arrangement may also include a lock cylinder 23, 23C, which is arranged to provide a connection with the second shaft 8 for rotating it towards a position where the cam 9 leaves the groove 10 of the latch. The lock cylinder 23C shown in this figure has the same Figure 3 Therefore, the second shaft may also include a third cam 26, by which the lock cylinder 23 is arranged to form a connection with the second shaft 8 for turning it towards a position where the cam 9 leaves the groove 10 of the latch. Figure 7 As shown, the second shaft has been rotated by applying a lock cylinder. For example, the lock cylinder has a protrusion 23A that is rotated by turning a key (or an electric actuator). The rotatable protrusion 23A in turn rotates the second shaft 8, for example via a third cam 26, as shown in the embodiment of the figure.

[0041] The control of the second shaft by the electric actuator can be realized, for example, in the manner shown in the figure. In the embodiment shown in the figure, the shaft arrangement 5 of the electric actuator comprises a lever 24, and the second shaft 8 comprises a second cam 25. The lever and the second cam are arranged to form a connection between each other for rotating the second shaft by means of the electric actuator. Figure 4 The arrangement is shown locked, the cam 9 being received in the groove 10 of the latch 6. For unlocking, the electric actuator 4 turns the shaft arrangement 5 and simultaneously turns the lever 24. The lever 24 in turn rotates the second shaft 8 via the second cam 25, whereby the cam 9 comes out of the groove 10 of the latch and, at the same time, the swing handle arrangement is unlocked.

[0042] The electric actuator 4 is an electric motor, but it can also be a solenoid actuator. If a solenoid actuator is applied, the shaft arrangement 5 of the actuator comprises a mechanism for turning the lever 24.

[0043] Thanks to the invention, a swing handle arrangement with a locking function can be installed more freely in a door or hatch, making daytime use possible, and the swing handle also remains connected to the frame during daytime use. Thus, the swing handle cannot be turned away from the frame without pulling the swing handle away from the frame. That is, during daytime use, the swing handle cannot be turned due to gravity or strong winds.

[0044] Furthermore, when the locking element 14 is used, the electric actuator and the lock cylinder can return to their initial position in which they are not inclined to rotate the second shaft 8 immediately after unlocking the swing handle arrangement. The arrangement according to the invention also makes it possible to turn the swing handle 1 back to the frame 2 without the latch 6 forming a barrier.

[0045] From the examples given above, it is obvious that the embodiments according to the invention can be implemented by a variety of solutions. In other words, the invention can be implemented in many different embodiments within the scope of the independent claims.
