Description

  The present invention provides a furniture case, a furniture part such as a door that is movably supported in or against the furniture case, and the movable furniture from a closed position to an initial open position. At least one discharge element (Ausstosselement) for moving the part, at least one drive unit for freely locking the discharge member, and operating the unlocking member using the movable furniture part It is related with the furniture provided with the lock release member which cancels | releases the lock | rock of a drive device which can do.

  This type of furniture is well known in the field of discharge devices, etc., called so-called “touch latch” mechanisms. Here, by exercising (touching) the push toward the movable furniture part, the lock release member is operated, and further, the drive unit is unlocked (latched). It is moved from its closed position to the first open position by the discharge member. In the process of closing the furniture part, when the drive device is locked, the lock release member is also locked once. This movable furniture part is carried to the closed position in the last part of the closed section either by the user's hand or by a hinge or tensioning device and held there.

  Since these movable furniture parts do not necessarily have the exact same closed position, there is an irregular unlocking section between the closed position and the unlocking position of this movable furniture part. It was. It has been found that a movable furniture part cannot reach the operation position of the unlocking posture even if the push is exercised.

  An object of the present invention is to provide an improved furniture that can avoid the disadvantages and the like based on the prior art by using the invention.

  The present invention solves this problem by having the unlocking member be a part of one unlocking mechanism formed and installed in order to bring the unlocking member into contact with a movable furniture part in a closed position without play. It is solved by. In this case, a simple structural solution is achieved by attaching a rotating body having an eccentric ring shape other than the unlocking member to the unlocking mechanism. There, the unlocking member and its rotating body are connected by a gear.

  Unlike the conventional technology in which once the drive device is locked, the lock release member no longer moves. In the case of this form of the lock release member according to the present invention, the lock release member assumes the closed position after the drive device is locked. When moved as part of the unlocking mechanism in the direction of the movable furniture part being taken, the unlocking member is moved together in the closing direction for each movement of the movable furniture part in the closed position. Measures are being taken. That is, every time the movable furniture part in the closed position moves, the unlocking process is started.

  In addition, the unlocking member isolated from the drive device is connected to the rotating body by a gear, and according to one particularly preferred embodiment of the present invention, the rotating body is used as a power storage body. It is configured to be impacted by the return member being formed and more conveniently to engage a drive gear disposed on the discharge member. Here, as a result of the drive gear moved during the rotational movement of the rotating body meshing with the rotating body, power is stored in the power storage body. Here, the power accumulator can be formed by a single tension spring or a spiral spring, which is tensioned via a drive gear which is advantageously installed in the release lever during the closing of the movable furniture part. It is done.

  When the meshing of the drive gear and the rotator is released, this is usually done when the drive is locked again and the movable furniture part is in the starting position. Is moved when the tension of the spring is loosened, and the movement of the rotating body is transmitted to the unlocking member based on the gear connection with the unlocking member. The unlocking member is moved toward the movable furniture part in the closed position, ie until the unlocking member contacts the movable furniture part without play.

  It is obvious that the present invention does not limit the use of a rotating body that receives an impact from a power storage body. Therefore, this unlocking member can be connected to, for example, a rod or gear device. The basic idea of the present invention is that after the drive device is locked, the unlocking member is moved in the direction of the movable furniture part in the closed position.

  In order to prevent the release member from pushing the movable furniture part from the closed position to the open position, according to another embodiment of the present invention, the acting force of the return member is the hinge, or its movable The furniture parts are adjusted to be smaller than the acting force of the auxiliary drive device that keeps the furniture parts in the closed posture.

  When starting the unlocking process, the movement of the unlocking member to the locking mechanism can be accomplished in various ways. According to another means, the reliable unlocking of the drive device can be performed when the unlocking mechanism is connected to the locking mechanism via a connecting part on the lever.

  The unlocking mechanism particularly suitable for the present invention includes at least one unlocking member, a rotating body in the form of an eccentric ring, a wedge-shaped adjusting body, an unlocking lever, and a rotating body. It has a return member linked to the top.

  In the present invention, the wedge-shaped adjusting body is, on the one hand, connected flexibly to the rotating body, in particular by means of a ball head joint, and on the other hand, a return member formed as a tension spring, in particular via a rocker joint. When pulling, the wedge-shaped adjusting body is configured to protrude from the tear between the rotating body and the unlocking lever. Further, when the tension of the return member is loose, it is connected so that it can enter into the rip using a rotating body, or it can be connected in this way, so that the lock release lever Based on the interruption, the unlocking member is moved toward the movable furniture part.

  In order to ensure meshing of the rotating body with the drive gear, according to another aspect of the present invention, a hairspring device is provided. Furthermore, in order to buffer the rotational movement of the rotating body unlocked by the return member, when a buffer body acting on the rotating body is prepared, this prevents the noise generated when colliding with the rotating body. It has been found that it is particularly advantageous.

  According to the second embodiment of the present invention, it is advantageous that the unlocking mechanism is an eccentric ring-shaped rotating body, but at least one unlocking member, together with the rotating body, in particular one A return member that is operatively connected via a pinion and a bearing component for the return member are provided.

  In the present invention, it is particularly advantageous if the return member is formed as a rotary shock absorber, and the rotary body is located on the rocker joint. It has also been found that a small number of single members are advantageous when they are directly and flexibly connected to the unlocking member.

  According to another embodiment of the present invention, the lever-like connecting part is rotatably connected to the bearing part at one end, and is provided at the joint at the other end opposite to the bearing part. It has a single detent formed to engage with the protrusion.

  The present invention also provides a way to open the furniture. This means that the unlocking member of the unlocking mechanism is in a closed position after the closing process or when it is finished, and is brought into contact with movable furniture parts.

  In addition to this, according to one particularly advantageous embodiment of the method according to the invention, it is contemplated that the play-free contact of the unlocking member is advantageously carried out using an eccentric ring-shaped rotating body. Yes. At that time, the rotating body has a power accumulating body or receives an impact of a return member formed as a power accumulating body, and is connected by a gear with a lock releasing member and particularly a rocker joint as an intermediate. Advantageously, the power accumulation of the return member is at least partially relaxed in order to bring the unlocking member into contact without play, and in particular during the closing process of the movable furniture part Power can be accumulated using the member.

  These illustrated embodiments are not intended to limit the scope of the utility model claims. Individual examples showing a number of possibilities are for realizing the idea as a device of a discharge device for movable furniture parts equipped with a discharge member, where the discharge process ends, Further, it is self-evident that the movable furniture part can be moved using a release member that is moved in the opening direction.

  FIG. 1 is a perspective view showing a general furniture 1 according to the present invention, in which a movable furniture part 3 is rotatably supported by a furniture case 2 using two hinges 28. The discharge device 4 is basically arranged in the interior of the furniture case 2 so that the movable furniture component 3, which is also rotatably supported by the discharge member 5, can be moved in the opening direction OR. It is installed on the same plane as the two leading edges.

  FIG. 2a is a top view showing a part of the furniture 1 shown in FIG. 1, in which the movable furniture part 3 is located in a closed final position. The space remaining between the furniture part 3 and the furniture case 2 is located at the rear of the movable furniture part 3 from its closed final position (further towards the closing direction), here the discharge Indispensable for carrying to the unlocking position in which the drive device for the member is unlocked. When the drive device is unlocked, the release member 5 pushes and moves the movable furniture part 3 to the first open position (FIG. 2b). The power storage body of the driving device is not completely loaded at this time, and the discharge member 5 has completed the discharge process. Reference numeral 26 designates the discharge member of the discharge device, which will be described in detail later. Up to the posture illustrated in FIG. 2b, the functional principle of the known “touch latch” mechanism is followed.

  The present invention starts from the posture illustrated in FIG. As in the case of the conventional “touch latch” mechanism, the open state of the movable furniture part 3 must be performed by the user's hand so as to exceed the initial open position illustrated in FIG. 2b. I must. This is because the discharge member 5 has already completed the discharge process. However, in the prior art, when the discharge member 5 moves the furniture part 3, the discharge device according to the present invention is shown in FIG. Means for moving the discharge member 5 beyond the initial open position.

  FIG. 2d shows a state in which both the movable furniture part 3 and the discharge member 5 are in a fully open position. The discharge member 5 is no longer in contact with the movable furniture part 3 when it is in a fully open position, but on the other hand it allows a simple structure of the discharge device. However, it is of course possible to bearing the discharge member 5 in the discharge device so that the discharge member 5 is in contact with the movable furniture part 3 even when it is fully open.

  In FIGS. 3a to 3c, different postures of the movable furniture part 3 are illustrated. FIG. 3 a is a view in which the movable furniture part 3 is in a closed position S in which it is basically aligned substantially parallel to the front of the furniture case 2. In FIG. 3b, the movable furniture part 3 assumes its initial open position, which corresponds to the attitude of the movable furniture part 3 after the discharge process has ended. β represents a bevel angle between the closed posture S and the first open posture O surrounded by the movable furniture part 3. After the release process, the movable furniture part 3 is moved by the user's hand over the initial open position O to its open final position E. Here, the bevel angle β ′ extends between the closed / posture S of the movable furniture part 3 and the opened final posture E.

  This open final position E does not necessarily correspond to the fully open position of the movable furniture part 3, as illustrated in FIG. 3c. That is, this bevel angle β ′ when the movable furniture part 3 is in the final opened position E is simply larger than the bevel angle β when the movable furniture part 3 is in the closed position. On the other hand, it has been pointed out that the bevel angle β ′ must be less than or equal to the maximum bevel angle when the movable furniture part 3 is in the fully open position.

  FIGS. 4a to 4c show different attitudes of the discharge member 5 that is rotatably supported in the discharge device 4 as in FIGS. 3a to 3c. FIG. 4a shows the discharge member 5 in the starting position S ′, which corresponds to the position of the discharge member 5 when the discharge device 4 is locked, and is movable furniture parts in the closed position. 3 is supported. FIG. 4b shows the attitude O 'of the release member 5 after the release process has ended. Here, the bevel angle α extends an angle surrounded by the posture O ′ of the discharge member 5 and the posture of the discharge member 5 taking the starting posture S ′. d represents the distance between the impact point of the release member 5 in the closed position S ′ and the impact point of the release member 5 after the end of the release process, whereas d ′ is the release member in the closed position S ′. 5 shows the distance between the impact point 5 and the impact point of the release member 5 after the opening of the movable furniture part.

  Comparing FIG. 4b with FIG. 4c showing the posture E ′ of the discharge member 5 after the opening process of the movable furniture part 3, the distances d and d ′ and the bevel angles α and α ′ are different in both postures. I understand that.

  The basic idea of the present invention is the posture E ′, which is located behind the posture O ′ in the opening direction of the discharge member 5 after the discharge process, and the opening process of the movable furniture part 3 It is in the point that it moves to the attitude | position corresponding to the attitude | position of the discharge | release member 5 after completion | finish. As a result, when the movable furniture part can be coupled with the discharge member 5 at the time when the closing process starts or immediately after the start of the closing process, Accumulation of power is already started in the first part of the closed section. On the other hand, in the case of a known device, the accumulation of power in the power accumulation body is performed in a part of the closed section of the movable furniture part that is in the closed position.

  In the present invention, the discharge member after the discharge process is formed so that the discharge member can freely move in the open section after the discharge process is completed in relation to the power storage body of the driving device. With this configuration according to this latching principle of the discharge device, the power accumulator can always be impacted, i.e. in any position, but basically the entire section where the movable furniture part returns when closed. It can be used for accumulation in the power accumulator. Here, on the other hand, the section in which the movable furniture part returns during the accumulation process in the power storage body is selected to be larger than the section in which the movable furniture part returns during the release process, so the user can extend it. It is necessary to apply a small amount of power for accumulating in the power accumulator based on the determined section.

  In the second method, the return section of the movable furniture part in the accumulation process (Ladevorgang) and the discharge process (Ausstossvorgang) is basically made equal in length, and this part is made into a closed section of this movable furniture part or It is placed in the immediate vicinity of the open final position in the open section. As a result, the user starts applying the power accumulated in the power storage body at the same time as the start of the closing process, so the user has the impression that the force required for the closing process of the movable parts is uniform. Will be given.

  Based on the two illustrated embodiments of FIGS. 5a to 15 and FIGS. 16a to 28, the function transition of the furniture according to the present invention in the opening process and the closing process will be described in detail below. To do.

  Here, FIG. 5a is an exploded view showing a first embodiment of the discharge device 4 according to the present invention. All the parts of the discharge device 4 according to the present invention are arranged in a closed case 20, in which case the case cover is not shown for reasons of good visibility. The discharge member 5 which is rotatably set in the case 20 is shaped as a single arm lever and is provided with an upper part 27 and a lower part 27 '. A pulley 29 is rotatably disposed at the end opposite to the turning center, and the rotation axes of the pulley 29 and the discharge member 5 are basically parallel to each other. With this pulley 29 as an intermediate, the discharge member 5 is connected to a movable furniture part.

  Between the lower part 27 ′ and the upper part 27 of the discharge member 5, a bearing member 13, a joint 16 and a connecting member 14 which are also rotatable and coaxial with the discharge member 5 are arranged. In the bearing member 13, the pinion 12 and the braking body 19 that are connected so as not to be twisted are rotatably supported in an axis that is basically parallel to the rotation axis of the discharge member 5 to the bearing member 13. Has been. The pinion 12 is formed to mesh with a gear-shaped portion Z (FIG. 5 b) in contact with the upper portion 27 of the discharge member 5, while the braking body 19 is a gear-shaped portion disposed on the joint 16. Formed to bite Z '. Further, a guide member 30 is disposed between the joint 16 and the brake body 19, and when this is used, the teeth attached to the brake body 19 are accurately bitten into the gear-shaped portion Z ′. In other words, when the brake body 19 is engaged with the joint 16, the tooth tip of the brake body 19 is prevented from coming into contact with the tooth tip of the gear-shaped portion Z ′.

  In the case of the embodiment shown here, the medium for moving the ejection member 5 is two auxiliary drive devices 23, 23 '. The auxiliary driving devices 23 and 23 'are formed with the initial open posture as a basic state. In this case, the auxiliary drive device 23 ′ in the form of a helical spring is provided with a stop member installed in the case in order to secure a free wheel required for the movement of the discharge member 5 between the brake body 19 and the joint 16. The bearing member 13 whose mobility is restricted by 22 is pressed in the opening direction. The second auxiliary drive 23 'is shaped as a torsion spring, the first arm 24 of which grips the upper part 27 of the discharge member 5, while the second arm 24' is rotatable and in place. Is connected to the case 20 of the discharge device 4.

  Furthermore, a drive device 6 for the discharge member 5 is arranged in the discharge device 4, which is in the form of a tension spring, a power storage body 8 loaded by hand, a support clip for the power storage body 8 ( Haltebuegel) 7 and adjustment body 9 for adjusting power storage body 8 are provided. Since the adjusting body 9 is arranged in the case 20 so that it can be taken in and out from the outside, simple and easy adjustment of the power accumulating body 8 is ensured. Since the power accumulating body 8 formed as a tension spring of the driving device 6 is hung on the concave portion 10 of the connecting member 14 at one free end thereof, when the force of the power accumulating body 8 is loosened, the connecting member 14 is moved toward the driving device 6.

  In the embodiment shown here, the driving device 6 is locked via a toggle lever 17 and a dead point mechanism. Here, one free end of the control handle 18 of the first toggle lever 17 is rotatably connected to the connecting member 14. The other second handle 18 'is freely rotatable but is disposed in the case 20 of the discharge device 4 in a stationary manner. The dead point mechanism is rotatably connected to the toggle lever 17 at one end and a lever 15 rotatably connected to the joint 16 at the other end. The lock of the driving device 6 is such that the joint 16 is engaged with the braking body 19 when the release member 5 is loaded on the power storage body 8 and the connecting member 14 is connected to the joint 16 and the power storage body 8. This operation is performed by locking the toggle lever 17 and the connecting member 14 based on being moved to the right until the accumulation is completed.

  The driving device 6 is unlocked by the unlocking member 26, the eccentric ring-shaped rotating body 33, the hairspring 32 for the rotating body 33, the wedge-shaped adjusting body 34, the unlocking lever 35, the buffer 36 and the buffer 36. The unlocking mechanism 25 constituted by the return member 37 for the rotating body 33 that receives the impact of is performed as an intermediate. The connection of the unlocking mechanism 25 to the lever 15 of the dead point mechanism is in particular a lever-shaped connecting part 38, which is rotatably connected to the unlocking lever 35 at one end thereof, and on the opposite side. At the end, the lever 15 or the joint 16 of the dead point mechanism that is rotatably connected is used as an intermediate.

  FIG. 6 a shows the unlocking device 4 when the power storage body 8 is locked. The movable part 3 is in a closed position, and at that time, the unlocking member 26 of the unlocking mechanism 25 is in contact with the movable furniture part 3 without play. Basically, the non-playing contact of the unlocking member 26 with the movable furniture part 3 using the wedge-shaped adjusting body 34 that receives the impact of the return member 37 will be described in detail later.

  For reasons of better visibility, the cover of the case 20 and the upper part 27 of the discharge member 5 are not shown in the drawing. In this posture shown in the figure, power is stored in the power storage body 8 of the drive device 6. That is, the tension spring forming the power storage body 8 is supported in the spring retainer 7 and is in a tensioned state by the connecting member 14. The case 20 has an outlet opening 21 for the discharge member 5 and the release member 26 on the front side facing the movable furniture part 3. All other parts of the discharge device 4 are arranged in a closed case 20 except for the adjusting body 9 for the power storage body 8.

  The power accumulator 8 is locked with a toggle lever 17 acting on the connecting member 14 as an intermediate, which is locked in the posture shown in the drawing via the lever 15 of the dead point mechanism. The discharge member 5 is locked in its starting position S ′ via an auxiliary drive device 23 formed as a torsion spring. Here, one arm 24 ′ of the spring is placed on the fulcrum 40 of the case, and the second arm 24 of the auxiliary drive device 23 is placed flexibly on the fulcrum 39 of the lower part 27 ′ of the discharge member 5. Further, an auxiliary drive device 23 is arranged.

  Since the fulcrum 39 is positioned on the right side of the line V connecting the discharge member 5 and the center of rotation of the fulcrum 40 in the starting posture of the discharge member 5 (FIG. 6b), the auxiliary driving device 23 causes the discharge member 5 to be It is ensured that it remains locked. Based on the rotational movement of the discharge member 5 during the discharge process, the fulcrum 39 moves to the left until it exceeds the line V, so that the auxiliary drive unit 23 hits the discharge member 5 in the opening direction. That is, the auxiliary drive device 23 formed as a rotary compression spring is locked by the dead point mechanism in the same manner as the drive device 6.

  Therefore, in this illustrated posture, the connecting member 14, the joint 16 and the discharge member 5 cannot move freely based on the posture of the locked toggle lever 17 or the auxiliary drive device 23, but on the other hand, the bearing member 13 and the pinion 12 The brake body 19 can move while rotating. Here, the bearing member 13 receives an impact of the auxiliary drive device 23 ′ formed as a coil spring, and receives an impact from the auxiliary drive device in the opening direction of the movable furniture part. The teeth bite into the Z part of the upper part 27 of the discharge member 5 which is shaped like a gear.

  Since the bearing member 13 is pushed back by the joint 16 with the auxiliary drive device 23 ′ as an intermediate, it is possible to secure a free wheel required between the joint 16 and the braking body 19 during the opening process. That is, when the brake body 19 is engaged with the gear portion Z ′ of the joint 16 in the opening process, the pinion 12 and the discharge member 5 are blocked due to this. That is, the impact on the movable furniture part 3 by the discharge member 5 is completely impossible in such an arrangement.

  FIG. 6b differs from FIG. 6a only in that one drive gear 41 is formed on the upper part 27 of the discharge member 5. FIG.

  FIG. 7 shows the movable furniture part 3 in the unlocking position A, which is located behind the closed position S of the furniture part 3 that is movable in the closing direction SR. In the case of the embodiment shown here, the free furniture part 3 is moved from the closed position S to the unlocked position A by being pressed against the movable furniture part by the user's hand. When the movable furniture part 3 is used, the lock release member 26 is further moved into the case 20, and the lock release lever 35 is moved to the left via the wedge-shaped adjusting body 34. Here, the unlocking member 26, the wedge-shaped adjusting element 34 and the unlocking lever 35 are formed and arranged so as to be moved by a gear as a part of the rocker joint. Since the lever 15 of the dead point mechanism is also moved to the left through the L-shaped lock release lever 35 and the lever-shaped connecting part 38, the toggle lever is blocked and the power storage body 8 is unlocked. Is done.

  Even though this illustrated unlocking mechanism represents one advantageous embodiment, the present invention is not limited by this illustrated embodiment. Therefore, instead of using the movable furniture part 3, it is possible to realize the unlocking of the discharge device by using, for example, a switch, a key or by directly pushing the unlocking member 26. Can also be assumed.

  In FIG. 8, the release process is finished, and the movable furniture part 3 has reached its initial open posture O. By loosening the power accumulator 8, the connecting member 14 is moved to the left, and the releasing member 5 is moved from the case 20 in the opening direction OR through the connecting member 14. The coupling of the release member 5 with the movable furniture part 3 is here carried out via a pulley 29, so that the movable furniture part 3 can easily slide along the discharge member 5. The joint 16 similarly moves in the opening direction OR with the lever 15 connected to the toggle lever 17 bent at one end thereof as an intermediate. That is, the joint 16 remains between the brake body 19 and the gear-shaped portion Z ′, and the joint 16 is moved so as to open far enough to leave a tear, so that the discharge member 5 (not shown). The pinion 12 meshing with the gear-like portion Z of the upper portion 27 is provided with a rotational property.

  Further movement of the bearing member 13 struck in the opening direction OR by the auxiliary drive device 23 ′ is prevented by the stop member 22 (FIG. 5 a) set in the case 20.

  Further, referring to FIG. 8, the fulcrum 39 for the arm 24 of the auxiliary drive 23, which is formed as a rotary compression spring, is compared with FIG. 6b, the pivot point of the discharge member and the fulcrum 40 of the auxiliary device 23. Here, the auxiliary device 23 gives an impact to the discharge member 5 in the opening direction OR. Here, the acting force of the auxiliary drive device 23 is movable only to the discharge member 5, but with its power, the movable furniture part 3 adjacent to the discharge member 5 is arranged with the discharge member 5 as an intermediate. It is chosen not to be enough to open further.

  Using the auxiliary drive device 23, not only the discharge member 5 but also the movable furniture part 3 can move beyond the initial open posture O to the final open posture E so that the auxiliary drive device can move to a size that can be moved. It is self-evident that the action force of 23 can be selected as well. In this type of conventional configuration, when the user closes the movable furniture part 3, in addition to the power required to be stored in the power storage body 8, the user is relatively free to load the auxiliary drive device. Because it requires a lot of power, it gives the user the impression that the furniture parts are heavy and movable. On the other hand, since the acting force of the auxiliary drive device 23 is as large as possible, the furniture 1 equipped with the movable part 3 and the discharge device 4 can be realized. Here, in order to move the movable furniture part 3 from the closed position to the final open position, the user needs to release the lock of the discharge device 4 by, for example, pushing the movable furniture part. The movable furniture part 3 is moved to its open end position by the discharge member 5 in the first movement stage and further using the auxiliary drive device 23 in the next movement stage. There is no need to help.

  On the other hand, in the case of the illustrated embodiment, the acting force of the auxiliary drive device 23 is sufficient to guide the discharge member 5 to the movable furniture part 3 later. The force applied by the user's hand when closing the movable furniture part 3 is such that the user cannot feel it at all.

  The final opening position E of the movable furniture part 3 is shown in FIG. In comparison with FIG. 8, it can be seen that the postures of the movable furniture part 3, the discharge member 5, and the auxiliary driving device 23 are changed. The force of the auxiliary drive device 3 is relaxed, and the movable furniture part 3 is carried to the final open position E by the user's hand, so that the discharge member 5 follows the movement of the movable furniture part 3. I was able to. The attitude of the pinion 12 has also changed in relation to the gear-shaped part Z arranged in the upper part 27 of the discharge member 5, in other words, the engagement of the pinion 12 on the part Z on the gear is here: It is bitten at a point further away from the pulley 29 of the gear-shaped portion Z.

  Here, when the movable furniture part 3 is moved from its final opening position E in the closing direction SR, first, as shown in FIG. 10, the gear-like portion Z ′ of the joint 16 Will be engaged. As a result, the rotation of the pinion 12 along the gear-shaped portion Z is prevented in the discharge member 5, and the joint 16 enters the case 20 due to the movement of the discharge member 5 in the closing direction. The connecting member 14 is moved to the right via the joint 16 and the toggle lever 17 hinged thereto until the power accumulating body 8 of the driving device 6 completes the accumulation of power. At the same time, during this movement, power is also accumulated in the auxiliary driving devices 23 and 23 '(FIG. 11a).

  As will become more apparent from FIG. 10, the disc-shaped brake body 19 and the gear 16 of the joint 16 are fitted so that the tooth tip of the brake body 19 engages with the tooth base attached to the gear-shaped portion Z ′ of the joint 16. Since the portion Z ′ is positioned by the guide member 30 so as to mesh with each other, the discharge member 5 and the movable furniture part 3 are prevented from being moved unexpectedly.

  FIG. 11b differs from FIG. 11a in that the power accumulator 8 of the drive device 6 is in a locked state since the lever 15 of the dead point mechanism has already exceeded the dead point of the toggle lever 17. Therefore, the process of accumulating power in the power accumulating body 8 is completed before the movable furniture part 3 reaches its first open position O again. When the process of accumulating power in the power accumulating body 8 is completed, the unlocking member 26 of the unlocking mechanism 25 is movable without play on the remaining sections of the movable furniture part 3 in the closed section. It will contact the furniture part 3.

  In addition, as will be apparent from FIG. 11 b, a drive gear 41 is formed on the upper part 27 of the discharge member 5 so as to mesh with the rotating body 33 that takes the form of an eccentric ring of the unlocking mechanism 25. Yes. The eccentric ring-shaped rotating body 33 receives an impact from the adjustment spring 32 in the closing direction SR of the discharging member 5 in order to hold the rotating body 33 when the discharging member 5 is pushed into the case 20.

  In FIG. 12, the drive gear 41 has already gripped the eccentric ring-shaped rotating body 33 and takes it in the closing direction SR of the discharge member 5. During such movement of the discharge member 5, the lock member of the discharge device 4 for the power storage body 8 remains without moving, and at the same time the lock of the drive device is kept as it is.

  In FIG. 13, the fulcrum 39 of the auxiliary drive device 23 exceeds the line V connecting the turning center of the discharge member 5 and the fulcrum 40 of the auxiliary drive device 23 attached to the case 20. The discharge member 5 is now impacted in the opposite direction, i.e. the discharge member 5 is returned to its starting position by the auxiliary drive 23 and locked there. Since the drive gear 41 of the discharge member 5 carries the rotating body 33 to its final posture, the return member 37 is in a completely tensioned state. When the tension of the return member 37 formed as a tension spring is loosened, the eccentric ring-shaped rotating body 33 cushions the return motion of the rotating body 33, and makes the rotating body 33 collide with the rotating member 33. In order to avoid noise that may occur in one end posture portion, it is connected to the pinion of the shock absorber 36 via a gear-like portion (not shown). The wedge-shaped adjusting body 34 is moved together with the eccentric ring-shaped rotating body 33 by bearing the wedge-shaped adjusting body 34 in the ball socket formed on the eccentric ring-shaped rotating body 33 by the ball head. .

  In FIG. 14, the movable furniture part 3 takes the closed position S again, and the furniture part 3 is supported through, for example, a hinge 28. The rotating body 33 in the form of an eccentric ring is already fixed by the drive gear 41 by means of the hinge 28 of the release member 5 and is moved to the left by the return member 37. The wedge-shaped adjusting body 34 is also moved to the left by using this rotating body 33, so that the discharging member 26 is removed from the case 20 based on the rocker joint formed between the wedge-shaped adjusting body 34 and the discharging member 26. It moves toward the movable furniture part 3, that is, it moves until the unlocking member 26 comes into contact with the movable furniture part 3 without play (FIG. 15).

  The posture shown in FIG. 15 corresponds to the posture shown in FIG. 6b. That is, the release member 5 takes a starting position when the drive device 6 is locked, the movable furniture part 3 takes a closed position, and the unlocking member 26 moves without play. Adjacent to the free furniture part 3.

  FIG. 16a is an exploded view showing a second embodiment of the discharge device 4 according to the present invention, similar to FIG. 5a. The same parts are denoted by the same reference numerals, and detailed description of these parts is omitted.

  The second embodiment shown in FIGS. 16a to 28 is different from the first embodiment shown in FIGS. 5a to 15 in the structure of the unlocking mechanism 25. FIG. Moreover, the coupling structure with the joint 16 performed via the wedge-shaped connecting part 38 is different.

  In the case of the first embodiment, the unlocking mechanism 25 is provided with an unlocking member 26, a rotating body 33 in the form of an eccentric ring, and a buffer 36, in which a bearing part 42 and a rotation functioning as a return member are provided. A buffer 43 and a pinion 44 are included in the buffer element 36. Unlike the first embodiment, the unlocking member 26 is directly connected to the rotating body 33 having the shape of an eccentric ring via a rocker joint in the second embodiment. The coupling of the unlocking mechanism 25 to the joint 16 is performed again via a lever-shaped coupling component 38 that is rotatably coupled to the bearing component 42 of the buffer element 36 at one end thereof. That is, the bearing component 42 or the rotation buffer 43 based on the second embodiment assumes the functions of the lock release lever 35 or the return member 37 based on the first embodiment.

  On the opposite end, the lever-like connecting part 38 is connected to the joint 16 so that it cannot rotate freely. Instead, a detent 45 is set at the free end of the lever-shaped connecting part 38, which is formed to engage with the projection 46 formed on the joint 16. The joint 16 is rotatably connected to the lever 15 of the dead point mechanism for the toggle lever 17 on that side.

  Unlike the first embodiment, the second embodiment has only the auxiliary drive device 23 formed by a handle-like spring that acts between the connecting member 14 and the discharge member 5. The other difference is in the form of the surface of the disk-like braking body 19 as well as the corresponding part Z 'of the joint 16. In the case of the first embodiment, the engagement between the braking body 19 and the joint 16 is mainly based on the gear-like shape, and is exchanged for the engagement so that the shape fits closely. In the case of the second embodiment, The brake body 19 and the joint 16 mesh with each other by frictional contact.

  FIG. 17 shows the unlocking device 4 when the power storage body 8 is locked. The movable furniture part 3 is in a closed position S. At that time, the unlocking member 26 of the unlocking mechanism 25 is in contact with the movable furniture part 3 without any play. Power is stored in the power storage body 8 in the illustrated posture, and the driving device 6 is locked. Here, the locking is performed via the toggle lever 17 acting on the connecting member 14 that is locked in the illustrated posture through the lever 15 of the dead point mechanism.

  The discharge member 5 is locked in its starting position S using a hinge 28. The connecting member 14, the joint 16 and the release member 5 are not freely movable based on the movable furniture part 3 supported in the closed position by the toggle lever 17 and the hinge that are locked, Simultaneously with the bearing member 13, the pinion 12 and the brake body 19 can move freely. The free wheel necessary for the free wheel between the joint 16 and the braking body 19 is easily secured by the stopper 22 by colliding with the bearing member 13 in the case 20.

  In the case of this embodiment, it is necessary to take measures so that the supporting force of the hinge is larger than the acting force of the auxiliary drive device 23 that permanently gives an impact to the releasing member 5 in the opening direction OR of the movable part 3. is there.

  18 differs from FIG. 18b only in that the upper part 27 of the discharge member 5 is shown in a transparent manner (in a broken line). Moreover, in FIG. 18, pressure is already applied to the movable furniture part 3, and this can be confirmed based on the change in the posture of the lock release lever 15.

  FIG. 19 shows the movable furniture part 3 taking the unlocking position A from the closed position S further in the closing direction. At this time, the movable furniture part 3 is pushed by the user. Thus, it is moved from the closed posture S to the unlocked posture A. Since the unlocking member 26 is subsequently advanced into the case 20 by the movable furniture part 3, the rotating body 33, which exhibits its eccentric ring only due to the rocker joint, and together with this, The bearing part 42 is moved to the left. Since the joint 16 and the lever 15 of the dead point mechanism are simultaneously moved to the left through the detent 45 (FIG. 16a) provided on the connecting part 38 having a lever shape, the toggle lever 17 The interruption and the lock of the power storage body 8 are interrupted.

  In FIG. 20, the release process is complete, and the movable furniture part 3 has reached its first open position O. By loosening the tension of the power accumulator 8, the connecting member 14 was moved to the left, and the releasing member 5 was moved from the case 20 in the opening direction with the connecting member 14 in the middle. Since the release member 5 is coupled to the movable furniture part 3 via the pulley 29 in the same manner, the movable furniture part 3 can be easily slid along the discharge member 5. Further protruding movement of the bearing member 13 is prevented by a stopper 22 (FIG. 16a) set in the case.

  When the rotating body 33, which has an eccentric wheel that is moved to the left via the drive gear 41 of the discharge member 5 in the opening process, closes the movable furniture part after passing through the drive gear 41, the drive gear 41 is eccentric. Since it can return to the attitude | position which can hold | grip the rotary body 33 which exhibits the ring | wheel again, the balance spring 32 is provided between the case 20 and the rotary body 33 which exhibits the eccentric ring | wheel.

  The final open position E of the movable furniture part 3 is illustrated in FIG. 21a. Compared to FIG. 21 a, it is clear that the postures of the movable furniture part 3, the discharge member 5 and the auxiliary drive device 13 have changed. Since the movable furniture part 3 has been brought to the final open position E by the user's hand, the auxiliary drive 23 can relax the tension and the discharge member 5 follows the movement of the movable furniture part 3. I was able to. The attitude of the pinion 12 is also changed in relation to the gear-shaped part Z provided on the upper part 27 of the discharge member 5, i.e. the pinion 12 is engaged in this gear-shaped part Z here. Then, it is performed at the point of the gear-shaped portion Z further separated by the pulley 29.

  FIG. 21b corresponds to the attitude of the release member 4 shown in FIG. 21a, but the surface of the brake body 19 and the corresponding part Z ′ of the joint 16 are already geared in the first embodiment. Only the points that are formed are different. In addition, in order to avoid unexpected engagement of the brake body 19 with the joint 16, a guide member 30 is set on the joint 16.

  When the movable furniture part 3 is moved in the closing direction SR from its final open position, the brake body 19 is first a part Z ′ of the joint 16 as shown in FIGS. 22a and 23. Will be bitten. Accordingly, the rotation of the pinion 12 along the Z ′ portion of the discharge member 5 is prevented, and the joint 16 enters the case 20 by moving the discharge member 5 in the closing direction SR. The connecting member 14 is moved to the right through the clutch 16 and the toggle lever 17 fixed thereto until the accumulation of power in the power storage body 8 of the drive device 6 is completed. At the same time, the power is also accumulated in the auxiliary drive device 23 along with this operation.

  FIG. 22b also shows a variant in which the surface of the braking body 19 and a part Z ′ of the joint 16 are formed in a gear shape. Here, the gear-shaped part Z ′ of the braking body 19 and the joint 16 is inserted into the tooth base of the toothed part of the braking body 19 along the part Z ′ of the joint 16 each time. In addition, it can be seen that the guide member 30 is used to ensure that the movable parts 3 can be prevented from moving unexpectedly.

  FIG. 24 is different from FIG. 23 in that the power accumulation body 8 of the drive device 6 is in a locked state because the lever 15 of the dead point mechanism has already exceeded the dead point of the toggle lever 17. Therefore, the process of accumulating power in the power accumulator 8 is interrupted before the movable furniture part 3 reaches its initial open position O again. When the process of accumulating power in the power accumulator 8 is finished, the unlocking member 26 of the unlocking mechanism 25 is movable in the remaining part of the closed section of the movable furniture part 3. The furniture part 3 is adjacent to the furniture part 3 without play.

  In addition to this, as becomes clear from FIG. 25, a driving gear 41 is attached to the upper portion 27 of the discharge member 5 so as to engage the unlocking mechanism 25 with the eccentric ring-shaped rotating body 33. . The eccentric ring-shaped rotating body 33 receives the impact of the hairspring 32 as described above in order to ensure that the drive gear 41 grips the rotating body 33 when the discharge member 5 enters the case 20.

  In FIG. 25, the drive gear 41 has already gripped the eccentric ring-shaped rotating body 33, and this is entrained in the closing direction SR of the discharge member 5. During this movement of the release member 5, the locking member of the release device 4 for the power accumulator 8 does not change and at the same time the drive device 8 remains locked.

  FIG. 26 is a view in which the drive gear 41 of the discharge member 5 has carried the eccentric ring-shaped rotating body 33 to one end posture thereof. The eccentric ring-shaped rotating body 33 is connected to a pinion 44 and a rotation buffer 43 of the rotation buffer 36 via a gear-shaped portion (not shown) so as to buffer the return motion of the rotating body 33.

  In FIG. 27, the movable furniture part 3 has already taken the closed position S, which is supported by a hinge. Since the eccentric ring-shaped rotating body 33 is fixed via the drive gear 41 of the discharge member 5 and is moved to the left by the buffer body 36, it is formed between the eccentric ring-shaped rotating body 33 and the unlocking member 26. Based on the rocker joint, the unlocking member 26 is moved from the case 20 in the direction of the movable furniture part 3, that is, until the unlocking member 26 comes into contact with the movable furniture part 3 without play. (FIG. 28).

  The posture illustrated in FIG. 28 corresponds to the posture illustrated in FIG. That is, the release member 5 takes a starting position in the vicinity of the locked drive device 6, the movable furniture part 3 is in the closed position S, and the unlocking member 26 is in contact with the movable furniture part 3 without play. ing.
