Description

The present invention relates to an ejection mechanism, in particular for movable furniture parts, with a curved guide, along which a driver is movable, wherein the driver is biased by at least one energy storage in one direction and can be latched to the cam guide with tense energy storage in a closed position, and a with the driver at least in the closed position coupled activator, wherein the activator relative to the cam guide or the cam guide is movable relative to the activator, wherein in the closed position of the driver via a relative movement of the activator relative to the cam guide or a relative movement of the cam guide relative to the activator can be unlocked and a pullout guide and a discharge system.

The EP 1 845 821 discloses a drawer opening and closing apparatus in which the drawer is held in a closed position by a latching mechanism. The latching mechanism comprises a driver which can be coupled to a running rail, on which a rod is arranged, which is guided in a control cam. To unlock the drawer is pressed against the force of a spring, so that then the rod is released from the locked position in the control cam and can be moved together with the driver and the track rail. In such a device for opening and closing is disadvantageous that the unlocking of the locking mechanism is effected only by a depression of the drawer. In addition, the locking is done by a variety of components that can absorb only limited mechanical stress, since they are filigree and damage is to be expected.

The EP 2 174 572 shows an opening and closing device according to a post-published prior art.

It is therefore an object of the present invention to provide an ejection mechanism and a pullout guide, which is sturdy and allows easy unlocking of a driver.

This object is achieved with an ejection mechanism having the features of claim 1.

According to the invention, a pawl is arranged at a distance from the activator according to claim 1, the pawl passing through the catch in an opening direction can and in the opposite direction closing the pawl can be engaged to move the driver in the closing direction. Thereby, the ejection mechanism can be tightened by the pawl even before the closing position, which also allows the use of a self-closing, which pulls the activator after clamping the driver in a closed position.

To drive over the driver of the ejection device, the pawl can be performed pivotally perpendicular to the opening direction via a pivot point.

A deflection of the activator is conceivable by a translational movement, rotational movement, curved movement, pivoting and / or by elastic behavior due to the selected material of the contact areas. Optionally, the complete activator or latch deviates, alternatively, a partial evasion of individual components is possible. The counterforce to the return movement of the movable part can be applied by spring force, by elastic deformation, in particular of subcomponents. The effects described above can also be achieved by a construction according to a Richtgesperres, Schaltgesperres or jumpers.

The activator or the pawl may, for example, be linearly guided in oblong holes. In this embodiment, the activator or pawl can be returned to the home position by gravity or spring loaded. The activator or pawl may alternatively be equipped with moving parts. These pawls or moving parts can be controlled via cam guides, by gravity, by using elastic material or spring force to return to the starting position.

The driver preferably has two spring-loaded counter-acting pawls or levers which allow both a force application and a low-force driving over. These pawls have a restoring moment that, for example, by elastic deformation of an underlying element is achieved. This element has two sections, each section being associated with a pawl. An embodiment as a rocker or leaf spring is also conceivable. The pawls can only be overrun with low force in one direction. This functionality is needed especially if a multi-acting activator or multiple activators or pawls are used to control various devices. The pawls can be elastic, provided as a film hinge or with a storage.

To avoid false tripping, the triggering lever may be spring loaded to pressure in its home position. In the sense of a jump gear so a defined release force can be set. Only when this force is exceeded, the driver is completely brought from its rest position in the bent end portion of the cam guide. The ejection mechanism is thus activated.

In a cam-controlled system, the achievement of the open end position can be supported by an additional energy storage on the activator. Thus, a malfunction or damage to the modules, in particular in a deviating from the embodiment installation position, prevented.

By the guided in the cam guide 7 pin 12 of the driver 11 "is pivoted upon reaching the curved end portion 71. When opening the straight end portion of the cam guide 7 forms a pivot point for the driver 11" via the pin 12. By the guided in the cam guide 45 pin 10 of the driver 11 is pivoted "upon reaching the curved end portion 70. The respective pivoting of the driver 11" leads to the release of the activators 5 "and 41. Furthermore, allows the pivotal mounting of the activators 5" and 41 a driving over of the driver 11 "in the end positions of the driver 11" in the bent end portions 70 and 71 of the cam guides 7 and 45. Alternatively, the activators can also be performed, for example, vertically displaceable. In FIG. 1 the closed position of the drawer is shown, on which the driver 11 "is fixed to an angled end portion 71 of the cam guide 7 and is biased by the force of a spring 8 in the opening direction.

On the guide rail 2, a holder 46 for attachment of the energy accumulator 8 is provided. About a fixation 47 of the energy storage 8 is fixed to the holder 46. The other end of the force accumulator 8 designed as a tension spring is fixed to the driver 11 "with a spring eye via the bolt 48. In order to change the spring force, the fixation on the holder is designed to be displaceable and fixable.

In order to unlock the driver 11 "can be pulled on the drawer, so that then coupled to the running rail 3 activator 5" the driver 11 "pulls out of the angled end portion 71, as shown in the FIGS. 2A and 2B is shown. Then, the cam 11 "is moved in the opening direction by the force of the spring 8. Also connected to the track rail 3 is a second activator 41 which engages with a second cam 42 guided in a second cam track 43. The cam track 43 and the dog 42 are connected to a self-retraction 44 which in the closed position holds the drawer closed.The self-retraction 44 may further comprise a damper 49 for slowing a closing movement to avoid impact noise. a direct release after the closing process, avoided.

In the FIGS. 3A and 3B the activator 5 "comprises a downwardly projecting web 40 on which a front abutment surface 18" is formed, this abutment surface 18 "being adjacent to one of the abutments 11" Lever 25 which is rotatably mounted on the housing 6 "about an axis 26. The lever 25 may be biased in a starting position by a spring or moved by gravity into a starting position in FIG. 3B to the right and pivots the lever 25. As a result, reaches an upper stop edge 27 of the lever 25 against an underside of the driver 11 "and pushes it upwards out of the angled end portion 71 of the cam guide 7" out. Thus, the driver 11 "is not fixed by the lower projection 16" in the receptacle 14 "of the driver 11", the activator 5 "is also pivotally mounted and therefore by the lever 25 and the driver 11" clockwise slightly up to a Stop to be pivoted. Then pulls the driver 11 "after unlocking by the force of the spring 8, the activator 5" in the opening direction.

As a result, the activator 41 can be pivoted upwards on the carrier 11" via a run-on slope 56 be moved in the opening direction.

If the running rail 3 is moved in the closing direction, first the second activator 41 engages in the receptacle 14 "of the carrier 11" and pulls the carrier 11 "out of the parked position in order to tension the spring 8. The carrier 11" is in this case via a first pin 10 in a cam guide 45 and a second The cam guides 7 "and 45 each include an angled end portion 71 and 70, respectively, for pivoting the cam 11" at the end of the cam guides 7 "and 45, respectively. It is also possible to provide only a single cam guide with two angled end sections 70, 71.

During the closing movement of the driver 11 "is parked by the second activator 41 at the angled end portion 71 of the cam guide 7", wherein the pivoting of the driver 11 "of the activator 41 out of engagement with the driver 11" passes and moves the drawer further in the closing direction can be.

In order to bring the activator 5 "into engagement with the driver 11" is, according to the FIGS. 5A and 5B the drawer continues to move in the closing direction until the activator 5 "passes on a run-on slope 55 on the driver 11" and is thereby pivoted. The activator 5 "can then be displaced along the run-on slope 55 until it engages in the receptacle 14" on the catch 11 ". At the same time, the second catch 42 of the self-closing draws the second activator 41 into the closed position, so that the closing movement is shortly before The self-closing also serves to lock the movable furniture part or the drawer 50. The tumbler prevents accidental opening such as by vibration or slight inclination of the furniture in which the ejector with a drawer slide and a movable furniture part are installed.

Also in the in the FIGS. 1 to 5 In the embodiment shown, it is of course possible to provide two pullout guides which allow unlocking in accordance with the ejection system, even if a dog 11 "has been unlocked from the locked position by the unlocking action on only one side then for unlocking the other driver 11 "on the second pullout guide.

In FIG. 6 2 shows a further embodiment of a drawer slide 1 'according to the invention, which comprises a guide rail 2 and a running rail 3, wherein the same reference numerals are used for the same components. The driver 11 '"is guided along a cam guide 7"' on a housing 6 '"and biased by a spring 8 in the opening direction. The spring 8 is fixed on the end 11 "facing away from the driver by a bolt 80 on a holding web 81 and an adjusting bar 82, wherein on the holding web 81 openings and on the holding web 82 recesses are formed, in which the bolt 80 can be inserted. Thereby, the tension of the spring 8 can be adjusted.

On the driver 11 '", a first lever 91 is pivotally mounted on a receptacle and a second lever 92 is pivotally mounted on an opposite side of the driver 11'.

In FIG. 7 the pullout guide 1 '"is shown in a slightly open position, the second activator 41 abutting on the lever 92 on the cam 11'" to move the cam 11 "'out of the parking position along a slope 71"' of the cam guide 7 '" pull it out.

The driver 11 "'is now moved along the cam guide 7'" by the second activator 41 until the driver 11 '"reaches the angled end section 70'" and is pivoted downwards. As a result, the activator 41 is released and the running rail 3 can be moved without coupling with the driver 11 '"in the closing direction.

In FIG. 9 the latching position is reached when the activator 5 '"reaches the driver 11'". The activator 5 'then passes over the pivotable lever 91 and thereby moves between the levers 91 and 92. The second activator 41 then comes into engagement with the driver 42, which is movable along the cam guide 43 and through the self-closing mechanism 44 in the closing direction is moved until the closed position is reached.

In the Figures 10A and 10B the closed position of the pullout guide is shown. The activator 5 '"is in engagement with the driver 11'" and can be unlocked both by a movement of the running rail 3 in the closing direction and in the opening direction.

In FIG. 10B the position of the activator 5 '"on the driver 11"' is shown enlarged. The activator 5 '"is locked behind the lever 91, the lever 91 being pushed up by a spring, whereby the activator 5" can now engage the lever 91 and the driver 11'"to move by a pulling movement the drawer 11 '"to move back in the opening direction.

Alternatively, it is according to the Figures 11A and 11B it is possible to unlock the driver 11 '"by pushing in the drawer, then a web 40 of the activator 5'" directed downwards engages and presses a rotatably mounted lever 25 about an axis 26 so that the lever 25 moves the driver 11 '". During the opening process, the second activator 41 can now move via the lever 92, in which case the lever 92 is pivoted and is swung back again into the initial movement by the force of a spring is avoided by the slope 70 '"of the cam guide 7'".

After unlocking the driver 11 '"by the force accumulator 8 along the cam guide 7"' moves. The engaged activator 5 '"moves over the attached track 3, the coupled with her movable furniture part in the opening direction.

In FIG. 12 is a further embodiment of an ejection mechanism according to the invention for a pullout guide 1 "" shown. In FIG. 12 there is shown an ejection mechanism comprising a modified housing 60 in which a first cam guide 61 is formed with a bevel 63 at one end and an angled end portion 62 at the opposite end. Further, a groove-shaped recess 64 is formed as a second curve guide, which extends obliquely downward in the opening direction. In the horizontal direction, a third cam guide 65 is formed. For mounting a lever 25, a recess 66 is further provided, into which an axle 26 engages. By means of the lever 25, a driver 11 "" can be unlocked, which has a first pin 10 and a second pin 12, both of which are guided in the cam guide 7 "". The driver 11 "" is biased in the opening direction via a force accumulator 8, designed as a tension spring. The housing 60 is formed in two parts, so that on both sides of the driver 11 "" a corresponding housing part with the cam guides 61, 64 and 65 is formed.

On a running rail or a drawer bottom, a holder 89 is provided which in the closing direction against a stop 90 of an activator 5 "" can be applied. The activator 5 "" is guided between the two housing parts of the housing 6 "" and comprises a first vertical receptacle 83, in which a pawl 81 is resiliently mounted, a second vertical recess 84, in which a second pawl 80 is resiliently mounted, and a third vertical receptacle 85 for a locking pin 87. The pawls 80 and 81 are biased downwards by springs, to act on the driver 11 "". The locking pin 87 is movably mounted in the vertical direction in the activator 5 "".

In the FIGS. 13A and 13B the ejection mechanism is shown on a pullout guide with a guide rail 2 and a movable running rail 3. The ejection mechanism is in a closed position in which the cam 11 "" is locked to the angled end portion 62 of the cam guide 61. The activator 5 "" comes to rest on an elastic stop 31 "" which is received in a holder 32 "". The elastic stop prevents overpressure, a direct, re-triggering of the ejection device during or shortly after the closing operation. As in FIG. 13B is shown, the drawer can be opened by pulling, in which case the holder 89 acts on the locking pin 87, which in turn moves the activator 5 "" in the opening direction, so that the pawl 80 via its projection 16 "" the driver 11 "" from the locked position pulls. Further, an opening can be achieved by moving the drawer in the closing direction, in which case the abutment surface 18 "" of the opposite pawl 81 acts on the lever 25, which pivots about the axis 26 and thereby the driver 11 "" from the angled end portion 62 raises. The driver 11 "" then slides with the two pins 10 and 12 in the cam guide 7 "" due to the force of the force accumulator 8 up to the inclined portion 63rd

In FIGS. 14A and 14B is the driver 11 "" arrived at the inclined portion 63. The driver 11 "" is pivoted by the leadership of the pin 10 on the slope 63 downwards, so that the pawl 80 out of engagement with the driver 11 "" passes. The pawl 80 can now be moved over the driver 11 "" and the second pawl 81 has a run-on slope and can be pressed by the contact with the driver 11 "" up against the force of a spring and moved in the opening direction. By the movement in the opening direction of the locking pin 87 is moved downward, wherein the locking pin 87 is guided by a guide pin 88 in a corresponding recess of the activator 5 "".

In the FIGS. 15A and 15B the running rail 3 has been further moved in the opening direction, wherein the projection 90 is still applied to the block 89. The locking pin 87 has been moved down along the obliquely downwardly extending guide 64 and has now released the block 89. As a result, the running rail 3 can be moved further in the opening direction and is now decoupled from the activator 5 "".

The Figure 15A shows recordings for fixing the force accumulator 8, designed as a tension spring, on the housing 6 "". In the opposite in two housing parts of the housing 6 "" arranged receptacles a bolt for fixing the force accumulator 8 is inserted at one end. The bolt is designed so that it can be inserted at different positions in the receptacles of the housing 6 "" to change the force of the force accumulator 8 designed as a tension spring. At the driver 11 "", the other end of the force accumulator 8 is fixed by a bolt.

For a closing operation, the running rail is then moved so far in the closing direction until the block 89 abuts the projection 90, so that the activator 5 "" is moved a piece in the closing direction until the in the Figures 16A and 16B shown position is reached. In this position, the block 89 between the projection 90 and the locking pin 87 is locked again and the pawl 81 abuts a projection of the driver 11 "" at. As a result, the driver 11 "" is now moved in the closing direction along the cam guide 61 until the driver 11 "" pivots downward with the pin 12 on the angled end section 62 and is thus locked. Then that is in the FIGS. 13A and 13B reached shown position.

In FIG. 17 In the assembled position, another embodiment of an ejection mechanism is shown.

A push element 101 is designed as a drawer and can be mounted movably in a furniture body. For this purpose, a guide rail 102 a pull-out guide is provided on which at least one running rail is movably mounted. The running rail is located in a hollow side frame 103 of the drawer and a bottom 105 of the drawer is fixed via a plurality of holders 106 on the running rail. The direction of movement X of the pusher 101 is indicated by arrows in the drawings.

At the bottom of the bottom 105, a housing 107 is mounted, which consists essentially of two plate-shaped housing parts, are recessed on the slot-shaped cam guides 108, 109 and 110. In the housing 107 projects a web-shaped activator 116 which is fixed to the furniture body or the stationary guide rail 102. Activator 116 is only partially illustrated for clarity.

The pusher element 101 is held in a closed position via a retraction device 104, such retraction devices 104 being known as self-closing devices and being able to be mounted in a compact design adjacent to the pull-out guide.

In FIG. 18 the ejection device according to the invention is shown in a closed position. The collection device 104 comprises a collection housing 140 with a curve guide 141 with an angled end section 142. In the entry curve guide 141 a Einzugsmitnehmer 143 is movably mounted, which is coupled to a web-shaped Einzugsaktivator 144. With the feeder housing 140, a damper 145 is coupled, also located in the feeder housing 140, a spring for biasing the Einzugsmitnehmers 143 in the closing direction. As a result, the pull-in activator 144 arranged on the movable push element 101 or the running rail is pretensioned in the closing direction. The retraction device 104 may further comprise a damper to decelerate a closing movement before reaching the closing movement.

In FIG. 18 Furthermore, the web-shaped activator 116 can be seen, which is fixed at the end in a receptacle of a driving carriage 113. The driving carriage 113 comprises on the side facing away from the activator 116 side, a first movable pawl 114 and a second movable pawl 115, which are resiliently mounted and can be pressed into the driving carriage 113. In the closed position, the second pawl 115 is in engagement with a driver 111 which is movably mounted via pins in the first cam guide 118. The driver 111 is biased via an energy storage in the form of a tension spring 112 in the opening direction. The remote from the driver 111 end of the spring 112 may be fixed to the housing 107. The driver 111 is latched to an angled end portion 171 of the cam guide 108 against the force of the spring 112. At the opposite end of the cam guide 108, an angled end portion 170 is also formed, on which the driver 111 is pivotable.

Since the driver 111 is in the latched position, acting on the housing 107 via the Mitnehmerschlitten 113 no forces in the opening direction. The retractor 104 holds the pusher 101 in the closed position.

In FIG. 19 the ejector is shown when unlocking the driver 111. For this purpose, the thrust element 101 is pressed into the furniture body, so that the first pawl 114 against a pivotable ejector lever 130th suppressed. The ejector lever 130 is movably mounted on the housing 107 about an axis 131. One leg 132 of the ejector lever 130 abuts against the pawl 114, while the opposite leg 133 rests against the driver 111. By pushing the pusher 101, the ejector lever 130 is rotated counterclockwise about the axis 131 so that the leg 133 moves the pawl 111 out of the angled end portion 171 of the cam guide 108. As a result, the driver 111 is unlocked and now pulled by the force of the spring 112 along the cam guide 108. The driver 111 abuts with a tip 150 against a stop 151 of the driver carriage 113, so that the driver carriage 113 is moved together with the driver 111. Thereby presses an integrally formed wall 117 against the stationary activator 116, so that the housing 107 is moved together with the pusher 101 in the opening direction.

In FIG. 20 the ejector is shown in a slightly open position. The driver 111 is located in a central region of the first cam guide 108 and is further acted upon by the spring 112 with a force. As a result, the driving carriage 113 is also moved to the right, wherein the driving carriage 113 can be moved along a second curved guide 110. The cam guide 110 is formed linearly and the driving carriage 113 therefore moves linearly along the housing 107 via guide means. A movable stop 118, which can be moved via a pin 119 in a third cam guide 109, is also provided on the driving carriage 113. The third cam guide 109 is arranged inclined to the second cam guide 110, so that the stop 118 is moved when moving the cam carriage 113 to the right in Figure 40 down. The stop 118 is held perpendicular to the direction of movement of the carrier carriage 113 in a slot 120 movable.

At the in FIG. 20 In the position shown, the retraction device 104 is decoupled from the retraction activator 144, since the catch 143 has been moved along the retraction curve guide 141 to the angled end section 142 and is parked there in a pivoted manner. As a result, the pull-in activator 144 is released and can now continue to move independently of the pull-in cam 143 in the opening direction.

In FIG. 21 the ejector is shown in a position in which the driver 111 has reached the angled end portion 170 and thereby pivoted. In the pivoted position, the pawl 115 and the carrier slide 113 continue to move independently of the driver 111 to the right, so that the housing 107 is moved together with the pusher 101 in the opening direction. The thrust element 101 is no longer accelerated by the force of the spring 111.

The movable stop 118 is moved further along the cam guide 109 and continues to lower, wherein the activator 116 is still held in the receptacle between the movable stop 118 and the wall 117.

In FIG. 22 For example, the ejector is shown in a position in which the movable stopper 118 has been moved down so far that the web-shaped activator 116 is released. Thus, the housing 107 can now be moved together with the Mitnehmerschlitten 113 in the opening direction, that is independent of the stationary activator 116. In the further opening movement, the first pawl 114 slides over the driver 111 and is briefly pushed up against the force of a spring and latched behind the driver 111 again, wherein on the pawl 114 for this purpose a corresponding run-on slope 124 is formed.

In FIG. 23 a position is shown when the pusher 101 is moved back in the closing direction. First, the pawl 114 engages the driver 111 and pulls it out of the parked position at the angled end portion 170, wherein the driver 111 is moved against the force of the spring 112 along the cam guide 108. In this case, the driving carriage 113 is supported with the wall 117 on the activator 116, so that the driving carriage 113 is moved along the cam guide 110.

In FIG. 24 a position of the ejector is shown before reaching the closed position. The driving carriage 113 is moved so far along the cam guide 110, that the movable stop 118 is again arranged back to the activator 116 and this is now held between the stop 118 and the wall 117. The first pawl 114 has traversed the driver 111 along the curve guide 108 so far that the spring 112 is largely tensioned. In the position shown, the pull-in activator 144 now engages the pull-in catcher 143, so that it is unlocked and the pull-in device 104 is activated.

In FIG. 25 the ejector is shown before reaching the closed position when the driver 111 has reached the angled end portion 171 and is now locked against the force of the spring 112. As a result, the driver 111 pivots and the first pawl 114 can now be moved over the driver 111. The entrainment carriage 113 is now moved further along the second cam guide 110, wherein the retraction device 104 now pulls the thrust element 101 in the closing direction so that it can be moved by the user after tensioning the spring 112 and locking the entrainment device 111 without further use of force. The pusher 101 thus enters automatically.

In FIG. 26 the ejector is shown shortly before reaching the closed position. The second pawl 115 now slides with a run-on slope over the driver 111. The driver carriage 113 is still moved by the retraction device 104 in the closing direction.

In FIG. 27 the closing position is shown in which the second pawl 115 is latched behind the tip 151 of the driver 111. The pawl 115 is also resiliently mounted on the driving carriage 113. The movable stop 118 is extended again by the movement along the cam guide 109 and in the slot 120 and the activator 116 is therefore enclosed between the movable stop 118 and the wall 117. A spring buffer 122 prevents the ejection device unintentionally re-initiating an opening operation after the closing operation. Furthermore, the diaphragm gap is generated via the spring buffer 122, in order to enable a triggering of the ejection device by pressure in the closing direction.

When unlocking the thrust element 101 was pressed into the furniture body, so that an unlocking of the driver 111 is carried out via the Auswerferhebel 130. However, it is also possible to unlock the driver 111 by pulling on the thrust element, since then the driver 111 is pulled out of the angled end portion 171 and then without movement of the ejector lever 130 in FIG. 28 shown position can be shown. The driver 111 is again in a central portion of the cam guide 108 and is unlocked. Incidentally, the ejecting operation and the subsequent closing are performed as described above.

The ejection devices according to the invention can be used with all linearly displaceable furniture parts, for example with sliding doors.

Claims (4)

1. An ejection mechanism, in particular for movable furniture parts, having a curve guide (7, 7'", 7"", 108), along which a driver (11", 11"', 11"", 111) is movable, the driver (11", 11"', 11"", 111) being pre-tensioned in one direction by at least one force accumulator (8, 8', 112), and being able to be latched on the curve guide (7, 7'", 7"", 108) with tensioned force accumulator (8, 8', 112) in a closed position, and an activator (5", 5'", 5"", 106), which can be coupled to the driver (11", 11'", 11"", 111) at least in the closed position,, whereby a ratchet (41, 81; 114, 115) is provided, whereby the ratchet (41, 81; 114, 115) can pass the driver (11", 11'", 11"", 111) in an opening direction and the ratchet (41, 81) can be coupled on in the opposing closing direction, in order to move the driver (11", 11'", 11"", 111) in the closing direction, characterized in that the ratchet (41, 81; 114, 115) is mounted so it is pivotable, and can be latched behind the driver (11", 11'", 11"", 111) during an opening movement or the activator (5", 5'", 5"", 116) comprises a displaceable or pivotable part (92), which can be latched behind the ratchet (41, 81) during an opening movement.
2. The ejection mechanism according to Claim 1, characterized in that the ratchet (41, 81; 114, 115) can be coupled to a self-retractor (44), by means of which the activator (5", 5'", 5"", 116) is movable into a closed position.
3. The ejection mechanism according to Claim 1 or 2, characterized in that the ratchet (41, 81; 114, 115) moves the driver (11", 11'", 11"", 111) in the closing direction up to an end position, at which the driver (11", 11'", 11"", 111) is pivoted and thus decoupled from the ratchet (41, 81).
4. The ejection mechanism according to one of Claims 1 to 3, characterized in that a ratchet (41, 81; 114, 115) is arranged at a distance from the activator (5", 5"', 5"", 116).
