[0001] Sliding door fittings for a sliding door arrangement

[0002] Description

[0003] The present invention relates to a sliding door fitting for a sliding door arrangement.

[0004] A sliding door fitting for a piece of furniture is designed to guide the movement of the sliding door from a first position, in which the sliding door is open and the furniture is accessible, to a second position, in which the sliding door is closed and the furniture is closed. Sliding door fittings can also support the sliding door, thereby supporting the weight acting on it.

[0005] From DE 37 31 123 A1 a device for guiding sliding door elements is known, comprising a first and a second carriage, which can each be moved into a closed position and an open position.

[0006] Based on this, the present invention is based on the object of proposing a sliding door fitting for guiding a first sliding door and a second sliding door, which prevents a simultaneous movement of a first and a second sliding door of the sliding door arrangement.

[0007] To achieve the object, a sliding door fitting for guiding a first sliding door and a second sliding door is provided, comprising: a first guide element which can be connected to the first sliding door, and a second guide element which can be connected to the second sliding door, a guide arrangement via which the first guide element can be guided from a first closed position to a first open position and via which the second guide element can be guided from a second closed position to a second open position, with a first transfer arrangement which can be moved along a first movement axis from a retracted position to an extended position, wherein the first guide element is held in the first closed position in the retracted position of the first transfer arrangement and is arranged displaceably on the guide arrangement in the direction of the first open position in the extended position of the first transfer arrangement,with a second transfer arrangement which is movable along a second movement axis from a retracted position into an extended position, wherein the second guide element is held in the second closed position in the retracted position of the second transfer arrangement and is arranged displaceably on the guide arrangement in the direction of the second open position in the extended position of the second transfer arrangement, wherein the guide arrangement has a locking element which is arranged on the guide arrangement so that it can be moved by the first transfer arrangement and the second transfer arrangement, and wherein the locking element is moved into a first locking position in which the movement of the first transfer arrangement along the first movement axis is blocked when the second transfer arrangement is arranged in the extended position.

[0008] The sliding door fitting according to the invention has the advantage that a simultaneous transfer of the first transfer arrangement and the second transfer arrangement into the extension position and thus a collision of the two sliding doors is prevented.

[0009] In a possible embodiment of the sliding door fitting, the locking element can be moved into a second locking position in which the movement of the second transfer arrangement along the second movement axis is blocked when the first transfer arrangement is arranged in the extended position.

[0010] In another possible embodiment, when the first transfer assembly and the second transfer assembly are each arranged in the retracted position, the locking element can enable the movement of the first transfer assembly along the first movement axis and the movement of the second transfer assembly along the second movement axis. In one embodiment, the locking element can be connected to the guide assembly so as to be pivotable about a pivot axis.

[0011] A further embodiment is conceivable in which the first transfer arrangement can have a first locking element roller that is rotatable about a first axis of rotation perpendicular to the first movement axis. The first locking element roller can be in contact with the locking element in the extended position and / or in the retracted position of the first transfer arrangement. Alternatively or in combination, the second transfer arrangement can have a second locking element roller that is rotatable about a second axis of rotation perpendicular to the second movement axis. The second locking element roller can be in contact with the locking element in the extended position and / or in the retracted position of the second transfer arrangement.

[0012] The sliding door fitting can comprise a cam disc that is firmly connected to the guide assembly. The first locking element roller can be in contact with the cam disc in the retracted position and / or in the extended position of the first transfer assembly. Alternatively, or in combination, the second locking element roller can be in contact with the cam disc in the retracted position and / or in the extended position of the second transfer assembly.

[0013] In a further possible embodiment, the first transfer arrangement can have a first support element roller that is rotatable about a third axis of rotation perpendicular to the first movement axis. In this case, the first support element roller can be in contact with a first support element in the extended position and / or in the retracted position of the first transfer arrangement. Alternatively or in combination, the second transfer arrangement can have a second support element roller that is rotatable about a fourth axis of rotation perpendicular to the second movement axis. In this case, the second support element roller can be in contact with a second support element in the extended position and / or in the retracted position of the second transfer arrangement.

[0014] The first transfer arrangement can comprise a first carriage element and a first spring element. The first locking element roller and the first support element roller can be supported against one another via the first spring element. The first locking element roller and the first support element roller can each be arranged on the first carriage element so as to be displaceable along a spring axis of the first spring element. The spring axis of the first spring element can be arranged transversely to the first movement axis. Alternatively or in combination, the second transfer arrangement can comprise a second carriage element and a second spring element. The second locking element roller and the second support element roller can be supported against one another via the second spring element. The second locking element roller and the second support element roller can each be arranged on the second carriage element so as to be displaceable along a spring axis of the second spring element.The spring axis of the second spring element can be arranged transversely to the second movement axis.

[0015] A distance between the first rotational axis and the third rotational axis in the retracted position of the first transfer arrangement can be greater than in the extended position of the first transfer arrangement. Thus, a spring force of the first spring element acting on the first locking element roller can be smaller in the retracted position of the first transfer arrangement than in the extended position of the first transfer arrangement. Alternatively or in combination, a distance between the second rotational axis and the fourth rotational axis can be greater in the retracted position of the second transfer arrangement than in the extended position of the second transfer arrangement. Thus, a spring force of the second spring element acting on the second locking element roller can be smaller in the retracted position of the second transfer arrangement than in the extended position of the second transfer arrangement.

[0016] The spring force of the first spring element can be adjustable via first adjustment means. In particular, the spring force of the first spring element can be adjustable in the extended position and / or in the retracted position of the first transfer arrangement via the first adjustment means. Alternatively or in combination, the spring force of the second spring element can be adjustable via second adjustment means. In particular, the spring force of the second spring element can be adjustable in the extended position and / or in the retracted position of the second transfer arrangement via the second adjustment means. A distance between the cam disc and the first support element can be greater in a plane in which the first axis of rotation and the third axis of rotation lie in the retracted position of the first transfer arrangement than in the extended position of the first transfer arrangement.Alternatively or in combination, a distance between the cam disc and the second support element in a plane in which the second axis of rotation and the fourth axis of rotation lie may be greater in the retraction position of the second transfer arrangement than in the extension position of the second transfer arrangement.

[0017] In the extended position of the first transfer arrangement, a contact force can act between the first locking element roller and the locking element, such that a pivoting moment about the pivot axis acts on the locking element, urging the locking element toward the second locking position. Alternatively, or in combination, in the extended position of the second transfer arrangement, a contact force can act between the second locking element roller and the locking element, such that a pivoting moment about the pivot axis acts on the locking element, urging the locking element toward the first locking position.

[0031] Figure 14 is a sectional view along the section plane XIV-XIV in Figure 6; and

[0032] Figure 15 is a sectional view along the section plane XV-XV in Figure 6.

[0033] Figures 1 to 15, which are described together below, show a sliding door fitting 1 for a piece of furniture. The sliding door fitting 1 has a guide assembly 5 designed to guide and / or support a sliding door assembly.

[0034] The sliding door arrangement in this case comprises a first sliding door 2 and a second sliding door 2'. A first guide element 3 is rotatably attached to the first sliding door 2 via a first support element 4. A second guide element 3' is rotatably attached to the second sliding door 2' via a second support element 4'. The first and second guide elements can each be configured as guide rollers.

[0035] The guide assembly 5 comprises a rail assembly 6 having a first rail 7 and a second rail 8. The first rail 7 is arranged between the sliding doors 2, 2' and the second rail 8, so that the first rail 7 can also be referred to as the front rail 7 and the second rail 8 as the rear rail.

[0036] The first rail 7 is designed such that both the first guide element 3 can be moved from a first closed position to a first open position and the second guide element 3' can be moved from a second closed position to a second open position on the first rail 7. In the first closed position of the first guide element 3, the first sliding door 2 is arranged such that a part of the furniture assigned to the first sliding door 2 is closed, and in the first open position of the first guide element 3, the first sliding door 2 is arranged such that a part of the furniture assigned to the first sliding door 2 is accessible.In the second closed position of the second guide element 3', the second sliding door 2' is arranged such that a part of the furniture assigned to the second sliding door 2' is closed, and in the second open position of the second guide element 3, the second sliding door 2' is arranged such that a part of the furniture assigned to the second sliding door 2' is accessible.

[0037] The second rail 8 is designed such that additional guide elements, which are rotatably connected to one of the sliding doors, can be slidably arranged thereon. The first rail 7 and the second rail 8 are designed to be parallel, at least in sections.

[0038] The guide arrangement 5 also comprises a transfer-locking arrangement 9 by means of which the first guide element 3 and the second guide element 3' can each be transferred from a retracted position to an extended position. The retracted position of the first guide element 3 corresponds to the first closed position of the first guide element 3. The retracted position of the second guide element 3' corresponds to the second closed position of the second guide element 3'. In this respect, in the respective retracted position, the respective sliding door 2, 2' assigned to the guide element 3, 3' is closed. In the extended position, the respective sliding door 2, 2' assigned to the guide element 3, 3' is partially open and the guide element 3, 3' can be moved on the first rail 7 such that the respective sliding door 2, 2' assigned to the guide element 3, 3' is fully opened.The transfer blocking assembly 9 and the rail assembly 6 are designed integrally with each other. In this respect, the guide assembly 5 can also be referred to as a guide module.

[0039] To transfer the first guide element 3 from the retracted position to the extended position, the transfer-locking arrangement 9 comprises a first transfer arrangement 10, which can be transferred from a retracted position to an extended position. To transfer the second guide element 3' from the retracted position to the extended position, the transfer-locking arrangement 9 comprises a second transfer arrangement 10', which can be transferred from a retracted position to an extended position.

[0040] The first transfer arrangement 10 comprises a carriage element 11, which can be transferred along a movement axis B_11 from a retracted position to an extended position. In this case, the movement axis B_11 of the carriage element 11 is linear. For this purpose, the carriage element 11 is guided on a linear guide 39. However, it is also conceivable for the movement axis B_11 of the carriage element 11 to have a shape other than a straight line.

[0041] A partial section 12 of the first rail 7 and a partial section 13 of the second rail 8 are integrated into the slide element 11. In the retracted position of the slide element 11, the partial section 12 of the first rail 7 forms a holding section on which the first guide element 3 is held in the retracted position or the first closed position.

[0042] In the extended position of the carriage element 11, the partial section 12 of the first rail 7 is arranged such that a further partial section of the first rail 7 adjoins the partial section 12 of the first rail 7, so that a continuous rail section of the first rail 7 is formed by the two partial sections. In the extended position of the carriage element 11, the partial section 13 of the second rail 8 is arranged such that two further partial sections of the second rail 8 are connected to one another via the partial section 13 of the second rail 8, so that a continuous rail section of the second rail 8 is formed by the three partial sections. The term “continuous rail section” should be understood to mean that the guide element can be guided on the rail, whereby parting lines should be harmless.

[0043] The first transfer arrangement 10 comprises a locking element roller 14, which, between the retracted position and the extended position of the first transfer arrangement 10', is at least partially in contact with a cam disk 34. The cam disk 34 has a first guide contour 35. When the first transfer arrangement 10 is transferred from the retracted position to the extended position, the locking element roller 14 runs on the first guide contour 35. The cam disk 34 also has a second guide contour 36. When the second transfer arrangement 10' is transferred from the retracted position to the extended position, a locking element roller 14' runs on the second guide contour 36. The cam disk 34 is connected to the guide arrangement 5 via a fastening arrangement 33. The fastening arrangement 33 comprises one or more spacer sleeves, in the present case four spacer sleeves.

[0044] In the present case, the locking element roller 14 is permanently in contact with the cam disk 34 between the retracted position and the extended position of the first transfer arrangement 10. The locking element roller 14 is mounted on the carriage element 11 for rotation about a rotation axis D_14. The rotation axis D_14 of the locking element roller 14 and the movement axis B_11 of the carriage element 11 are arranged transversely to one another, in particular orthogonally to one another. For this purpose, the carriage element 11 has a first sliding element 15 on which the locking element roller 14 is rotatably mounted. The first sliding element 15 is displaceably arranged in a first sliding channel 16 of the carriage element 11.

[0045] The first transfer arrangement 10 comprises a support element roller 17, which, between the retracted position and the extended position of the first transfer arrangement 10, is at least partially in contact with a support element 37. The support element 37 has a support contour 38. When the first transfer arrangement 10 is transferred from the retracted position to the extended position, the support element roller 17 runs on the support contour 38. In other words, in the present case, the support element roller 17 is permanently in contact with the support element 37 between the retracted position and the extended position of the first transfer arrangement 10.

[0046] The support element roller 17 is mounted on the carriage element 11 for rotation about a rotation axis D_17. The rotation axis D_17 of the locking element roller 17 and the movement axis B_11 of the carriage element 11 are arranged transversely to one another, in particular orthogonally to one another. For this purpose, the carriage element 11 has a second sliding element 18 on which the support element roller 17 is rotatably mounted. The second sliding element 18 is displaceably arranged in a second sliding channel 19 of the carriage element 11.

[0047] The locking element roller 14 and the support element roller 17 are resiliently supported against one another via a spring element 20. The spring element 20 is connected at a first end to the first sliding element 15 and at a second end, opposite the first, to the second sliding element 18. The locking element roller 14 and the support element roller 17 are generally arranged so as to be displaceable towards one another. The locking element roller 14 can be arranged on the carriage element 11 along a first axis, and the support element roller 17 can be arranged so as to be displaceable on the carriage element 11 along a second axis. The first axis and the second axis can, in particular, be arranged parallel to one another, transverse to one another, or identical. In the present case, the locking element roller 14 and the support element roller 17 are each arranged so as to be displaceable on the carriage element 11 along a spring axis F_20 of the spring element 20.The first axis and the second axis are thus identical. The rotational axis D_14 of the locking element roller 14 and the rotational axis D_17 of the support element roller 17 are arranged parallel to one another in the present case. The rotational axis D_14 of the locking element roller 14 and the rotational axis D_17 of the support element roller 17 describe a plane in which the spring axis F_20 is also arranged. The shortest distance between the guide contour 35 of the cam disk 34 and the support contour 38 of the support element 37 varies depending on the position of the first transfer arrangement 10 or the carriage element 11 of the first transfer arrangement 10. In other words, the distance between the rotational axis D_14 of the locking element roller 14 and the rotational axis D_17 of the support element roller 17 varies depending on the position of the first transfer arrangement 10 or the carriage element 11 of the first transfer arrangement 10.By changing the distance between the rotational axis D_14 of the locking element roller 14 and the rotational axis D_17 of the support element roller 17, the spring force of the spring element 20 acting on the locking element roller 14 and the support element roller 17 changes depending on the position of the first transfer arrangement 10 or the carriage element 11 of the first transfer arrangement.

[0048] In the present case, the distance between the rotational axis D_14 of the locking element roller 14 and the rotational axis D_17 of the support element roller 17 is greater in the retracted position of the first transfer arrangement 10 than in the extended position of the first transfer arrangement 10. Thus, the spring force of the spring element 20 acting on the locking element roller 14 and the support element roller 17 is smaller in the retracted position of the first transfer arrangement 10 than in the extended position of the first transfer arrangement 10.

[0049] The preload of the spring element 20 is adjustable via adjustment means 21. In other words, the spring force of the spring element 20 acting on the locking element roller 14 and the support element roller 17 is adjustable via the adjustment means 21. In the present case, the adjustment means 21 are provided at the end of the second sliding element 18. The adjustment means 21 are thus in contact with the spring element 20.

[0050] The guide arrangement 5, in particular the transfer-locking arrangement 9, is configured mirror-symmetrically with respect to the symmetry axis E_sym. The second transfer arrangement 10' is thus arranged and configured mirror-symmetrically to the first transfer arrangement 10, with the individual elements of the second transfer arrangement 10' being identical to those of the first transfer arrangement 10. For the description of the second transfer arrangement 10', reference is therefore made to the preceding description of the first transfer arrangement 10. In the figures, corresponding elements are provided with the same reference numerals, with the elements of the second transfer arrangement 10' additionally being marked with an overline.

[0051] The transfer locking arrangement 9 has a locking element 22. The locking element 22 is pivotally mounted about a pivot axis S by a pivot bearing 31. In this case, the pivot axis S lies in the plane of symmetry E_sym. The locking element 22 is arranged between the cam disc 34 and the piece of furniture. The locking element 22 has recesses 32 corresponding to the number of spacer sleeves of the fastening arrangement 33, through which the spacer sleeves of the fastening arrangement 33 extend. The recesses 32 are designed such that the locking element 22 does not come into contact with the spacer sleeves of the fastening arrangement 33.

[0052] The locking element 22 can be pivoted by the first transfer arrangement 10 and by the second transfer arrangement 10' about the pivot axis S. For this purpose, a force is exerted on the locking element 22 by the locking element roller 14 of the first transfer arrangement 10 and by the locking element roller 14' of the second transfer arrangement 10', depending on the position of the respective transfer arrangement 10, 10'.

[0053] The blocking element 22 has a first adjusting contour 23, which can be brought into contact with the blocking element roller 14 of the first transfer arrangement 10. The first adjusting contour 23 comprises a blocking section 24 with which the blocking element roller 14 can be brought into contact when the first transfer arrangement 10 is in the retracted position. The first adjusting contour 23 comprises a holding section 26 with which the blocking element roller 14 is in contact when the first transfer arrangement 10 is in the extended position. Extending between the blocking section 24 and the holding section 26 is a transfer section 25, with which the blocking element roller 14 is in contact when the first transfer arrangement 10 is transferred from the retracted position to the extended position. The blocking section 24, the transfer section 25 and the holding section 26 can each be linear or have a shape deviating from a straight line.

[0054] The first adjusting contour 23 has, at least in sections, an identical profile to the first guide contour 35 of the cam disc 34. The locking element 22 can therefore be pivoted such that the first adjusting contour 23 is arranged in overlap with the first guide contour 35 of the cam disc 34 in a direction parallel to the pivot axis S, at least in the region of the transfer section 25 and the holding section 26.

[0055] The blocking element 22 has a second adjusting contour 27, which can be brought into contact with the blocking element roller 14' of the second transfer arrangement 10'. The second adjusting contour 27 comprises a blocking section 28 with which the blocking element roller 14' can be brought into contact when the second transfer arrangement 10' is in the retracted position. The second adjusting contour 27 comprises a holding section 30 with which the blocking element roller 14' is in contact when the second transfer arrangement 10' is in the extended position. Extending between the blocking section 28 and the holding section 30 is a transfer section 29, with which the blocking element roller 14' is in contact when the second transfer arrangement 10' is transferred from the retracted position to the extended position. The blocking section 28, the transfer section 29, and the holding section 30 can each be linear or have a shape deviating from a straight line.

[0056] The second adjusting contour 27 has, at least in sections, the identical profile to the second guide contour 36 of the cam disc 34. The locking element 22 can therefore be pivoted such that the second adjusting contour 27 is arranged in overlap with the second guide contour 36 of the cam disc 34 in a direction parallel to the pivot axis S, at least in the region of the transfer section 29 and / or the holding section 30.

[0057] If the first transfer arrangement 10 and the second transfer arrangement 10' are each in the retracted position, as shown for example in Figures 2, 4, 8 and 13, the locking element 22 is freely pivotable, i.e. essentially without force, between the locking element roller 14 of the first transfer arrangement 10 and the locking element roller 14' of the second transfer arrangement 10'. A movement of the first transfer arrangement 10 or the carriage element 11 along the movement axis B_11 or a movement of the second transfer arrangement 10' or the carriage element 11' along the movement axis B_11' is thus released in this state by the locking element 22. The release of the movement should be understood to mean that the respective movement is not blocked by the locking element 22.In this case, the locking element roller 14 of the first transfer arrangement 10 rests against the first guide contour 35 of the cam disc 34, and the locking element roller 14' of the second transfer arrangement 10' rests against the second guide contour 36 of the cam disc 34. The cam disc 34 completely absorbs the spring force of the respective spring element 20, 20' acting on the locking element roller 14 of the first transfer arrangement 10 and the locking element roller 14' of the second transfer arrangement 10'.

[0058] If the first transfer arrangement 10 is in the extended position and the second transfer arrangement 10' is in the retracted position, as shown for example in Figures 3 and 6, the locking element 22 is arranged in a defined manner between the locking element roller 14 of the first transfer arrangement 10 and the locking element roller 14' of the second transfer arrangement 10', wherein a free, or forceless pivoting of the locking element 22 is prevented by the spring force of the respective spring element 20, 20' acting on the locking element roller 14 of the first transfer arrangement 10 and the locking element roller 14' of the second transfer arrangement 10'.

[0059] In this case, the locking element roller 14 of the first transfer arrangement 10 rests against the holding section 26 of the adjusting contour 23 of the locking element 22 and applies the spring force of the spring element 20 to the locking element 22. Thus, a torque about the pivot axis S acts from the locking element roller 14 of the first transfer arrangement 10 on the locking element 22, which drives the locking element 22 in the direction of the second transfer arrangement 10'.

[0060] The locking element roller 14' of the second transfer arrangement 10' rests against the locking section 28 of the second actuating contour 27 of the locking element 22 and applies the spring force of the spring element 20' to the locking element 22. Thus, a torque about the pivot axis S acts from the locking element roller 14' of the second transfer arrangement 10' on the locking element 22. In the present case, the torque acting from the second transfer arrangement 10' on the locking element 22 drives the locking element 22 in the direction of the first transfer arrangement 10, wherein the torque acting from the locking element roller 14 of the first transfer arrangement 10 on the locking element 22 and the torque acting from the locking element roller 14' of the second transfer arrangement 10' on the locking element 22 are in balance. Here, the first adjusting contour 23 of the locking element 22 and the first guide contour 35 of the cam disc 34 overlap in the region of the holding section 26.Excess spring force of the spring 20, which would disturb the balance between the torques and drive the locking element 20 further in the direction of the second transfer arrangement 10', is thus absorbed by the cam disc 34.

[0061] In this case, the line of action of a contact force between the locking element roller 14' of the second transfer arrangement 10' and the locking section 28 of the second adjusting contour 27 of the locking element 22 intersects, for example, the imaginary connecting line of the rotation axis D_14 and the pivot axis S. In this case, the contact force between the locking element roller 14 of the first transfer arrangement 10 and the locking element 22 acts on the locking element roller 14 such that the locking element roller 14 is at least partially subjected to force in the direction of the partial section 12 of the first rail 7.For example, the contact force between the locking element roller 14 of the first transfer arrangement 10 and the locking element 22 can have a first force component along the spring axis F_20 in the direction of the support element roller 17 and a second force component in the direction of the movement axis B_11, wherein the second force component is directed in the direction of the partial section 12 of the first rail 7. In the case described above, a movement of the first transfer arrangement 10 or the carriage element 11 along the movement axis B_11 in the direction of the retracted position is released by the locking element 22. A movement of the second transfer arrangement 10' or the carriage element 11' along the movement axis B_11' is blocked in this state by the locking element 22. The locking element 22 is thus in a locked position with respect to the second transfer arrangement 10'.

[0062] In a first specific case, the line of action of the contact force between the locking element roller 14' of the second transfer assembly 10' and the locking portion 28 of the second adjusting contour 27 of the locking element 22 can pass through the pivot axis S when the first transfer assembly 10 is in the extended position and the second transfer assembly 10' is in the retracted position. In this first specific case, the contact force does not exert any torque on the locking element 22 about the pivot axis S.

[0063] In a second special case, the line of action of the contact force between the blocking element roller 14' of the second transfer arrangement 10' and the blocking section 28 of the second adjusting contour 27 of the blocking element 22 can run on the side of the pivot axis S which is opposite the axis of rotation D_14 of the blocking element roller 14 of the first transfer arrangement 10 when the first transfer arrangement 10 is in the extended position and the second transfer arrangement 10' is in the retracted position. In this second special case, the torque acting on the blocking element 22 from the second transfer arrangement 10' drives the blocking element 22 in the direction of the second transfer arrangement 10'.

[0064] In the first specific case and the second specific case, the transfer-locking arrangement 9 must comprise first return means which urge the locking element 22 in the direction of the first transfer arrangement 10, and second return means which urge the locking element 22 in the direction of the second transfer arrangement 10', since otherwise the locking element would remain permanently in the respective locking position.

[0065] The previously explained blocking effect of the blocking element 22 on the second transfer arrangement 10' occurs in the present case already between the retracted position and the extended position of the first transfer arrangement 10.

[0066] In this case, the locking element roller 14 of the first transfer arrangement 10 rests against the transfer section 25 of the adjusting contour 23 of the locking element 22 and acts on the locking element 22 with the spring force of the spring element 20. The locking element 22 is thus pivoted and held in the direction of the second transfer arrangement 10'.

[0067] The statements made previously for the case shown in Figures 3 and 6, in which the first transfer arrangement 10 is in the extended position and the second transfer arrangement 10' is in the retracted position, apply analogously to the case in which the first transfer arrangement 10 is in the retracted position and the second

[0068] Transfer arrangement 10' is in the extended position, as shown in Figure 11.
