Description

  The present invention provides a pull-in device (ie, pull-in or pull-out) for moving the movable furniture portion relative to the furniture body or for moving the drawer drawer guide rail. Device) comprising a tappet that is or can be biased by a force reservoir to bias the force on the rails of the movable furniture part or the drawer drawer guide part. The present invention relates to a drawer / drawing apparatus in which has a pull lever, and the pull lever is releasably connectable to a rail of a movable furniture part or a drawer drawer guide part.

  Furthermore, the present invention relates to a drawer drawer guide part provided with the above-mentioned drawer entry apparatus, a system comprising a drawer drawer guide part and a drawer entry apparatus, and furniture equipped with this type of system.

  Many configurations of the prior art are already known for devices that draw the movable furniture part into the closed end position. These devices detect the movable furniture part in its last closed area, so that the movable furniture part is automatically retracted into the furniture body without any further force from the user and in that position. Is held by a predetermined closing force. When opening the movable furniture part, the user first pulls the movable furniture part, stops the tappet at the pre-loaded ready position, and the rail of the movable furniture part or the drawer drawer guide part Until it is released again, a force must be applied against the spring resistance of the automatic retractor. Patent document 1 of the present applicant describes an automatic drawing device for a drawer that allows a tappet to travel along a straight traveling path and a curved portion following the straight traveling path. An automatic pull-in device with a pulling lever that performs a pivoting movement is known, inter alia, in US Pat. Prior art retractors allow the user to stretch the tappet or pull lever against the spring force under certain circumstances (especially in the case of large, bulky and heavily loaded drawers). It has become clear that the force applied can be significantly increased.

  The object of the present invention is therefore to provide a device of the kind mentioned at the outset, avoiding the drawbacks mentioned above.

  This object is achieved according to the invention by the features of claim 1. Further advantageous configurations are defined in the dependent claims.

  Therefore, in order to releasably connect the pull lever to the rail of the movable furniture part or drawer drawer guide part, the pull lever has at least two connection points or one connection point that is movable between two positions. Here, the above-described at least two connecting points or two positions where the movable connecting points are movable are spaced from each other along the length direction of the pull lever.

  In other words, in the opening process of the movable furniture part or when the drawer drawer guide part is opened, one connection point of the tappet is connected to the movably supported rail of the movable furniture part and / or the drawer guide part. Can be provided. Conversely, in the closing process, the other connecting part of the tappet (or the connecting part which is the same connecting part but at a different position compared to the opening process) is connected to the rail of the movable furniture part and / or the drawer drawer guide part. Can be linked.

  At least one “connection point” of the pull lever may at least partially form a shape fastening and / or a pressure fit connection. As a result, the pull lever can be releasably connected to the corresponding connecting member in its operating region. Similarly, the connection point of the tappet can also be realized purely as a contact area, in which case the connection member to be connected with the pull lever at least temporarily abuts against this area. In a further configuration, the connecting member can be provided to be slid and supported at the connecting point of the pull lever.

  It is particularly advantageous when the device according to the invention comprises a drawer drawer guide having a rail system of at least three parts. As is well known, such a guide part is, as is well known, a main body rail to be fixed to the furniture body, a loading rail associated with the movable furniture part, and a centrally supported displaceable between the main body rail and the loading rail. Rail. This type of drawer guide is often realized as a so-called full drawer or differential drawer. In the differential drawer, the loading rail associated with the drawer is moved at a relatively faster (eg, about twice) speed relative to the central rail being moved, which is achieved by a synchronizer known in the prior art. It becomes possible. With this type of synchronizer, a carriage supported displaceably between the central rail and the loading rail and a carriage supported displaceably between the main body rail and the central rail (or the central rail and the loading rail). The rails themselves) are always achieved such that they move at a predetermined speed rate relative to each other. Applicant's Yasukoku Patent No. 360,699 describes a possible embodiment of this type of synchronizer, in which a small gear rotatably supported on a central rail is connected by shape fastening. Synchronize both carriages. It is also possible that the small gear supported by the central rail directly meshes with the rack of the loading rail or the main body rail. The synchronizer can also be formed by a friction wheel supported on the central rail or by at least one control rope, which is connected to the body rail and the loading rail, and is connected to the two connecting rollers of the central rail Is being guided through. Furthermore, the person skilled in the art has the possibility of further embodiments for realizing a synchronization device, so that the loading rail moves at a faster speed than the central rail, where this speed ratio is substantially It may be constant or variably formed.

  In this type of controlled drawer drawer guide part, the central rail is connected to the first connection point of the pull lever when the drawer drawer guide part is opened, and at this time, the force storage part of the drawing device is It is expedient if the addition is made by movement of the central rail via a linked spring-biased pull lever. Due to the fact that the central rail moves at a slower speed than the loading rail, the force required to load the force reservoir (ie to tension the spring device) can be reduced. The spring-biased pull lever is therefore ready after moving through the predetermined path portion during the opening movement of the drawer drawer guide, where the central rail is decoupled from the pull lever and subsequently And can move freely. Due to the applicant's attempt, during the opening movement, the disconnection of the central rail from the tappet does not occur unexpectedly, so that the pull lever stops in the biased ready position and the rail in relation thereto. It has also been found that the user does not get the feeling that the movable furniture part is substantially accelerated when is disconnected.

  On the contrary, in the closing movement of the drawer guide part, it is convenient if the loading rail is connected to the second connection point of the pull lever. This 2nd connection location may be a connection location away from the 1st connection location, and may be the same connection location, and may take the position which warped from the start of an opening process at the time of the start of a closure process. . The involvement of the loading rail in the closing process has the advantage that the pulling force or possibly the buffering of the pulling movement can be applied directly to the loading rail and thus the movable furniture part. Therefore, in this case, the pulling force or the buffering force does not need to be transmitted through the control member of the drawer guide portion (that is, via, for example, a carriage or a synchronization device).

  The pull lever can be releasably connected to a corresponding connecting member, which can be realized in the form of a holding pin, for example. Accordingly, the central rail and the loading rail each preferably have one connecting member at the inner end of the main body, and this can be releasably connected to the connecting portion of the pull lever. Alternatively, the pull lever can be provided on the movable part of the drawer drawer guide part, in particular in a position in contact with the movable rail of the guide part or in the movable rail, or on the movable furniture part itself, Then, a corresponding connection member can be arrange | positioned in the part (especially main body rail) fixed to the main body of the drawer drawer guide part, or the furniture part itself.

  The pull lever is pivotally supported around the rotary bearing. The advantage of this embodiment is that the pivoting moment acting on the pulling lever increases as the pull-in path increases after the pivoting supported pulling lever exceeds the dead center position. Therefore, at the start of the pulling process, the initial pulling force is smaller, and the pulling force increases in the direction of the fully closed position of the movable furniture part. Therefore, the user does not feel that the movable furniture portion is pulled away from the hand at the start of the drawing-in process.

  In one advantageous configuration, the at least two coupling points described above are provided such that they are spaced or formed radially with respect to the rotary bearing of the pull lever. In this connection, the connecting points are spaced apart from each other by a passage, which is provided for a connecting member that can be connected to the pull lever, through which the movable furniture part or drawer drawer guide part can be connected. It is also advantageous if the movable rail can be pulled to an open end position and / or a closed end position.

  According to an embodiment of the invention, the force storage part has at least one spring device, and the preload of the spring device is such that the pull lever is at one end position of the drawer drawer guide part or the movable furniture part. Can be changed by moving from one end position to the starting point, where the pull lever is ready to be preloaded when the rail of the movable furniture part or drawer drawer guide part moves further Reach the position and release the movable furniture part or rail. The spring device may include at least one mechanical spring member or a gas pressure reservoir (eg, in the form of a gas pressure spring).

  Further, the spring device may be provided so as to act on the operating point of the pulling lever, and the operating point is disposed at a position shifted from the rotation bearing of the pulling lever (top dead center spring). In this way, it is possible to obtain a pulling lever that can be bent to a stable end position after exceeding the dead point. At one of these end positions, the pull lever engages the connecting member, and at the other end position, the connecting member can be disconnected from the tappet. Following this, a person can freely move the rail of the movable furniture part or the drawer drawer guide part.

  In a preferred embodiment of the invention, it can be provided that the movement of the pull lever caused by the force reservoir can be buffered by the shock absorber. In this way, among other things, the rails of the movable furniture part and / or the drawer drawer guide part can be buffered and moved in the final movement path. The shock absorber can be implemented as a liquid shock absorber, for example in the form of a rotary shock absorber with two shock absorber components that can rotate relative to each other during the shock absorber stroke. be able to. Alternatively, it can also be implemented as a linear shock absorber with a piston that can be displaced in a liquid chamber, in particular in a cylinder. This piston can be connected to a piston rod or slider, which can cause a buffer movement to the shock absorber.

  In a possible embodiment of the invention, at least one transmission lever is provided, which transmission lever is on the one hand connected or pullable with a pull lever, preferably on the other hand with a buffer. It can also be provided such that it is connected or releasably connectable to the piston rod, liquid chamber, cylinder and / or slider of the device. Here, the movement of the pulling lever supported by the spring can be guided directly to the shock absorber via the transmission lever. The advantage of the releasable connection via the fixing device is that it can be replaced without problems when the shock absorber fails. Here, the shock absorber can be operatively connected to the pull lever at least at the time of the shock absorbing process, or can be realized as an overrun shock absorber (or overrun brake). A rack and pinion system can be advantageously used.

  The drawer drawer guide portion of the present invention includes a main body rail to be fixed to the furniture body, a loading rail associated with the movable furniture portion, and a central rail supported displaceably between the main body rail and the loading rail. The central rail and the loading rail each have one connecting member, and these connecting members can be releasably connected to at least one connecting portion of the drawer / drawing device of the present invention.

  Patent protection is also claimed for a system having a drawer entry device for moving the movable furniture part relative to the furniture body or for moving the drawer drawer guide rail. This drawer / drawing device has a tappet that is energized or energized by a force storage unit to energize the rail of the movable furniture part or drawer drawer guide part, and is fixed to the furniture body A drawer drawer guide portion including a body rail to be to be carried, a loading rail associated with the movable furniture portion, and a central rail supported displaceably between the body rail and the loading rail, wherein the drawer When the drawer guide part is moved for opening, the central rail is connected to one connecting part of the tappet, and when the drawer drawer guide part is closed, the loading rail is connected to this connecting part or the second connecting part of the tappet. The In a preferred configuration, the tappet has the pull lever described above with at least two connection points or at least one movable connection point.

  Here, in the opening movement, it is expedient if the central rail moves the tappet through the connecting member to a stable preloaded position, where the tappet releases the connecting member.

  In the closing movement of the drawer drawer guide portion, conversely, first, the connecting member arranged on the central rail is not substantially obstructed in the tappet, preferably through the passage of the provided lever. It can be advantageous if the connecting member arranged on the loading rail can be releasably connected to the tappet. The rails thus connected can then be pulled to the open and / or closed end position by the force of the force reservoir.

  The furniture of the present invention is characterized by a system of the type described above.

  Further details and advantages of the invention will be explained on the basis of the following description of the drawings. In drawing

  FIG. 1 is a perspective view (perspective view) of the furniture 1 provided with the furniture body 2, in which the drawer 3 can be displaced relative to the furniture body 2 via the drawer drawer guide portion 4. It is supported by. For the sake of clarity, the top drawer 3 has been deleted, so that the drawer drawer guide 4 to be secured to the furniture body 2 can be seen in more detail. The drawer drawer guide portion 4 includes a body rail 5 to be fixed to the furniture body 2, a central rail 7 that is relatively movable with respect to the body rail 5, and a stacking rail 6 to be connected to the drawer 3. As a result, the drawer 3 can be pulled out completely relative to the furniture body 2.

  FIG. 2 is a perspective view (perspective view) of the drawer drawer guide portion 4 shown in FIG. What can be recognized here is a main body rail 5 to be fixed to the furniture main body 2 (FIG. 1) and a loading rail 6 to be connected to the drawer 3. Here, between the main body rail 5 and the loading rail 6. The central rail 7 is supported so as to be displaceable. In order to synchronize the movement of the rails, the synchronizer 8 is provided with a small gear that is rotatably supported on the central rail 7. A first carriage (not shown) is supported between the main body rail 5 and the central rail 7 so as to be displaceable, and a second carriage (not shown) is provided between the central rail 7 and the loading rail 6. These carriages are displaceably supported, and each of these carriages meshes with and is connected to the small gear of the synchronizer 8 via the meshing portion, thereby being controlled equally between the rails 5, 6, and 7. Movement can be triggered. At the inner end of the main body of the drawer drawer guide part 4, a drawer input device 9 is arranged, which in the illustrated embodiment draws at least one movable rail 6, 7 of the drawer drawer guide part 4, Or it is provided for drawing the drawer 3 into the closed end position. The drawing-in / out device 9 includes a tappet 10 that is movably supported. The tappet 10 can be releasably connected to the movable rails 6 and 7. For this releasable connection, the central rail 7 has a first connection member 11 and the loading rail 6 has a second connection member 12. When the drawer drawer guide part 4 is opened from the fully closed position, only the central rail 7 is first engaged with the tappet 10 of the drawer device 9 via the connecting member 11, so that further During the opening movement, the tappet 10 is moved, so that a load can be applied to the force storage, here in the form of a spring device (not shown). When the drawer drawer guide portion 4 is moved for closing, the connecting member 12 of the loading rail 6 is engaged with the tappet 10 starting from the open position of the guide portion, and the tappet 10 is preloaded. The loading rail 6 is pulled into the fully closed position by the force storage. Because of the system controlled by the synchronizer 8, the central rail 7 moves at about half the speed of the loading rail 6. Since the central rail 7 moves slowly, a load can be applied to the force storage portion even if the applied force is reduced (the principle of the pulley). On the contrary, the drawer drawer guide part 4 is closed by pulling in the loading rail 6. At this time, the force of the spring device or the braking force of the shock absorber for buffering the movement of the rails 6 and 7 is directly applied to the loading rail 6.

  3a to 3c are views showing the drawer / drawing device 9 as seen from various directions. FIG. 3 a is a side view of the drawing-in / out device 9 having the base 13 fixed to the main body. The base 13 is for housing or supporting the drawer / drawing device. The tappet 10 has a pull lever 15 supported so as to be pivotable around a rotary bearing 14, and the pull lever 15 is spaced apart from each other along the length of the pull lever 15 2. Two connecting portions 16a and 16b are carried. Both of the connecting portions 16 a and 16 b are arranged so that the distance in the radial direction is different from the rotation bearing 14 of the pull lever 15. The pull lever 15 has an action point 17 for the force storage 18, where the action point 17 is arranged offset from the rotary bearing 14 of the pull lever 15. The force storage unit 18 has at least one spring device 18a in the form of a pressing spring, for example. The other end of the spring device 18 a is supported by the spring base 19 of the base 13. The pulling lever 15 is in a stable end position in this figure, and bends to the second stable end position by turning or beyond the dead center position. At this time, the spring 18a is stretched. ing. Here, in the stretched position of the spring 18a (not shown), the movable rails 6 and 7 (FIG. 2) are pulled to the end position, and then the pull lever 15 takes the position shown in FIG. 3a again. In order to cushion this pulling movement, a shock absorber 20 is present, which in this illustrated embodiment is a cylinder 20a and a piston rod 20b that is movable relative to the cylinder (which is a cylinder). (Fig. 3b). Alternatively, all other shock absorbers 20 (particularly liquid shock absorbers) known from the prior art can be used, for example rotary shock absorbers with a rack and small gear system. can do. In order to buffer the movement of the pull lever 15 caused by the force storage 18, a transmission lever 21 is provided, which is connected on the one hand to the pull lever 15 via a hinge 22, Then, it is connected (preferably releasably) to the cylinder 20a of the shock absorber 20 via the fixing device 23. By providing the releasable fixing device 23 between the transmission lever 21 and the cylinder 20a of the shock absorber 20, there is an advantage that when the shock absorber 20 breaks down, it can be replaced without any problem. FIG. 3 b is a perspective view (perspective view) of the drawer / drawing device 9 as seen from above. In this figure, in particular, the piston rod 20b of the shock absorber 20 protruding from the cylinder 20a can be seen. Here, the free end of the piston rod 20b is supported by a stopper of the base 13. Therefore, the cylinder 20 a of the shock absorber 20 is displaced with respect to the base body 13 during the shock-absorbing stroke or the return stroke of the shock absorber 20. FIG. 3c is a perspective view (perspective view) of the pulling-in / out device 9 seen from below.

  FIG. 4 is a perspective view (perspective view) of the drawer drawer guide portion 4 including the main body rail 5, the central rail 7, and the stacking rail 6. In this figure, a drawer / drawing device 9 is provided to completely close the drawer drawer guide portion 4. The base 13 of the drawer / drawing device 9 is fixed to the main body, that is, directly to the main body rail 5 or to the furniture main body 2 (FIG. 1). FIG. 4 is a diagram showing the opening of the drawer drawer guide portion 4 where the connecting member 11 of the central rail 7 connects the pull lever 15 to the spring 18a via the lower connecting portion 16a. Pull against the force. Thereby, the spring 18a is stretched. Conversely, the connecting member 12 of the loading rail 6 remains unconnected during the opening process. In the illustrated embodiment, the two connecting members 11 and 12 are each formed as a pin and protrude (preferably horizontally) from the rails 6 and 7 in the intended assembly position.

  FIG. 5 is a view showing a position where the drawer drawer guide portion 4 is further opened. It can be seen that the stacking rail 6 having the connecting member 12 has moved in the direction of the open position more rapidly than the central rail 7. In this figure, since the lever 15 can be turned clockwise until the connecting member 11 of the central rail 7 is released by itself without an additional functional member, the connecting member 11 of the central rail 7 is FIG. 6 is a view showing a moment when the connection is just released from the connecting portion 16a of the pull lever 15. Therefore, the pull lever 15 pivoted around the rotary bearing 14 so that the region of the connecting point 17 of the pull lever 15 was pushed into the concave recess. As a result, the pull lever 15 can continue to stay in the ready position provided for the closing process without moving. The spring 18a of the drawer 9 is completely loaded at this position.

  FIG. 6 is a view showing the drawer drawer guide portion 4 in a further open position. In this figure, the central rail 7 is completely released from the connecting portion 16 a of the pull lever 15, and at this point, the central rail 7 can be freely moved by the user in the same manner as the loading rail 6. During this time, the pull lever 15 is held at the stop position where it is further preloaded by the spring 18.

  FIG. 7 is a diagram showing a closing movement process of the drawer drawer guide portion 4 when the drawer 3 moves from the position shown in FIG. 6 in the closing direction. During the closing movement, the connecting member 11 of the central rail 7 first moves through the passage 24 for the pulling lever 15 between the two connecting points 16a, 16b. 11 does not contact the pull lever 15. Instead, the connecting member 12 of the loading rail 6 is operatively connected to the upper connecting portion 16 b of the pulling lever 15. During further closing movement of the loading rail 6, the pulling lever 15 is released from the pre-loaded ready position by the connecting member 12 of the loading rail 6, and subsequently, the pulling lever 15 is moved to the dead center position. After that, the connecting member 12 (and thus the loading rail 6) is pulled in the direction of the closed position by the force of the biased spring device 18a (see FIG. 8), during which the lower connection of the central rail 7 is achieved. The member 11 is not involved in this closing movement at all. The loading rail 6 therefore continues to be pulled starting from FIG. 8 and further in the closing direction until reaching the fully closed position shown in FIG. It should be noted that the pull lever 15 draws an arcuate track by its pivoting movement, so that the connecting member 12 of the loading rail 6 is released shortly before reaching the full end position. In the fully closed position shown in FIG. 9, the connecting member 12 of the loading rail 6 is thus completely disconnected from the pull lever 15. Here, when the drawer drawer guide portion 4 moves again from the fully closed position shown in the drawing to the opening direction, the lower connecting member 11 of the central rail 7 starts operating again in the opening movement. This is as already described in detail in FIGS.

  FIGS. 10a to 10d again show the progress of the opening movement of the drawer drawer guide portion 4. FIG. Starting from the fully closed position shown in FIG. 10a, firstly only the connecting member 11 of the central rail 7 engages with the tappet 10 formed as a pulling lever 15, i.e. the connecting point 16a. The connecting member 12 of the loading rail 6 is not connected during the opening movement. In the middle of the opening movement, the spring 18a is stretched via the pulling lever 15, and this pulling lever 15 is turned by the movement of the central rail 7 in the outward direction. This is as illustrated in FIG. 10b. At this time, the loading rails 6 are not connected and do not substantially resist the user in the opening process. FIG. 10 c is a diagram illustrating a time point when the connecting member 11 of the central rail 7 is released by the turning movement of the pulling lever 15. In FIG. 10 d, the central rail 7 is completely disconnected from the pull lever 15 and can be moved freely by a person, similar to the loading rail 6.

  FIGS. 11 a to 11 d are views showing the progress of closing movement of the drawer drawer guide portion 4. When the closing member moves, the connecting member 11 of the central rail 7 first moves unobstructed through the passage 24 of the pulling lever 15 and is not connected to the pulling lever 15 at this time. This is as shown in FIG. 11b. On the contrary, the connecting member 12 of the loading rail 6 comes into contact with the other connecting portion 16b of the pulling lever 15, where the loading rail 6 causes the pulling lever 15 to pivot during further closing movement of the drawer drawer guide portion 4. Following this, the force of the spring device begins to act, causing the pull lever 15 to pivot, whereby the loading rail 6 connected to the pull lever 15 is pulled in the closing direction. This can be seen from FIG. 11c. FIG. 11d shows the drawer drawer guide 4 in the fully closed position. In this figure, the connecting member 12 of the loading rail 6 is released from the pull lever 15. In order to buffer the pull-in movement of the loading rail 6, a shock absorber 20 can be provided. This is as already described in FIGS.

  12a to 12f are views showing a further embodiment (second embodiment) of the present invention. FIG. 12 a is a view showing a drawer drawer guide portion 4 having a main body rail 5, a central rail 7, and a stacking rail 6. In this figure, the rails 6 and 7 are synchronized by means of a synchronization device 8 with a small gear (this device has already been described in FIG. 2). The withdrawal device 9 can be formed substantially equal to the device 9 of the previous figures. However, in FIG. 12b, instead of the two connecting points 16a and 16b of the pulling lever 15 being separated from each other, here, only one connecting point 25 is provided on the pulling lever 15, The connection point is supported so as to be movable along the length of the pull lever 15 between at least two mutually offset positions. The movable connecting point 25 is supported inside the elongated hole-like recess of the pulling lever 15 so as to be displaceable with respect to the pulling lever 15. It is supported so that the height can be adjusted relatively. The movable connecting point 25 of the pull lever 15 has at least one, preferably pin-shaped guide member 26, which is guided along a (preferably closed) control cam 27 of the base 13. Yes. In the illustrated embodiment, the control cam 27 is at least substantially trapezoidal. The movable connecting portion 25 is formed so that both the connecting members 11 and 12 of the central rail 7 or the stacking rail 6 can be supported so as to slide along the connecting portion 25. Therefore, as shown in FIG. 12 b, when the drawer drawer guide portion 4 moves from the completely closed position toward the open position, the guide member 26 of the connecting portion 25 is also moved by the connecting member 11 of the central rail 7. First, it is pulled along the horizontal portion of the groove-shaped control cam 27. Subsequently to the horizontal portion of the control cam 27, the control cam 27 shifts to a portion having a rising slope, whereby the guide member 26 of the connecting portion 25 is moved when the drawer drawer guide portion 4 further moves for opening. Lifted. The lifting of the movable connection point 25 also releases the connection member 11 of the central rail 7, while the connection point 25 is moved to the upper end of the control cam 27 having an inclination and is held here in the ready position. The This is as shown in FIG. 12c. Both the movable rails 6, 7 of the drawer drawer guide part 4 of FIG. 12 c can thus be moved further towards the open position without being connected.

  In the closing process of the drawer drawer guide portion 4, the connecting member 12 of the loading rail 6 comes into contact with the lifted connecting portion 25. This is as shown in FIG. 12d. In this closing movement, the dead point of the pulling lever 15 loaded on the spring by the applied force is overcome, and then the connecting member 12 of the loading rail 6 exceeds the movable connecting point 25 and the load is released. It is pulled to the closed position by the force of the spring device 18a. This is as shown in FIG. 12e. In order to buffer this pull-in movement, the buffer device 20 described in FIGS. 3a to 3c can be provided. In a further closing movement, the guide member 26 is disconnected from the connecting member 12 above the loading rail 6 by the lowered portion of the control cam 27, and subsequently the movable connecting point 25 is therefore guided by the control cam 27. It moves downward through the guide member 26, and is pushed again onto the connecting member 11 of the central rail 7 here. The central rail 7 is in the closed position already provided for this by the synchronizer 8 shown in FIGS. 2 to 12a. According to FIG. 12f, the drawer drawer guide part 4 has reached the ready position for the next opening process.
