  The main problem to be solved by the present invention is to further improve the usability of the operating mechanism of this type of rotating body.

In order to achieve the above object, in the present invention, the operating mechanism of the rotating body has the following configurations (1) to (3).
(1) A rotating body that is combined with the support so as to be able to rotate between a reference position and a deployed position and rotate from the reference position to a predetermined position opposite to the deployed position. ,
(2) The state in which the rotating body is in the reference position is releasably held by a holding mechanism including an urging member,
(3) Accumulation of the urging member of the holding mechanism is performed by rotating the rotating body to a predetermined position, and the linkage with the holding mechanism is released to allow the rotating body to rotate to the deployed position. When the rotating body reaches the unfolded position, the urging member urges the link with the holding mechanism to return, and the urging body rotates back to the reference position.

  According to this operation mechanism, the rotating body can be rotated beyond the reference position to the deployed position by performing a rotation operation to the predetermined position (hereinafter, this rotation operation is referred to as a release operation). Further, the rotating body that has reached the unfolded position can be rotated back to the reference position by the urging force of the urging member of the holding mechanism, and can be stably positioned at the reference position until the next release operation is performed.

  According to the apparatus of the present invention, the rotating body at the reference position can be rotated to the unfolded position beyond the reference position by performing the release operation. In comparison, when the rotating body is deployed, it is not necessary to continuously rotate the rotating body from the reference position to the deployed position.

  Hereinafter, based on FIGS. 1-6, the typical embodiment of the apparatus provided with the rotary body comprised by applying this invention is described.

  1 to 6 show an example in which the rotating body M constituting the support mechanism is the hook body 11 and the support body C constituting the support mechanism is the case body 10 that houses the hook body 11 at the reference position. ing. FIG. 1 shows the components disassembled. FIG. 2 shows a state in which the rotating body M is at the reference position, and FIG. 3 shows that the auxiliary slider 18 is pushed backward from the state in FIG. 4 is a state where FIG. 4 is a state in which the upper side of the rotating body M is further pushed backward from the state of FIG. 3 and the rotating body M is rotated to a predetermined position to move the slider 15 backward. 5 shows a state immediately after the pushing is stopped from the state shown in FIG. 4, and FIG. 6 shows a state where the slider 15 moves forward from the state shown in FIG. 5 by the urging of the compression coil spring 15g as the urging means. The state where the gear-like body 11f of the hook body 11 as the rotating body M is engaged again is shown.

  The actuating mechanism according to this embodiment includes a biasing means for rotating the rotating body M to the support C so as to be rotatable and for applying a biasing force toward the reference position to the rotating body M in the deployed position. Is. In the illustrated example, the mechanism is applied to a device attached to a room such as an automobile, an aircraft, a ship, or a railway vehicle, or various furniture or fixtures, and is used as an interior item or an accessory. It has become.

  Such an operating mechanism includes a support C and a rotating body M that is combined with the support C so as to be rotatable between a reference position and a deployed position. And it is comprised so that utilization of the rotary body M or the support body C may be made in this deployment position. Further, the rotating body M is further combined with the support body C so as to be rotatable from the reference position to a predetermined position opposite to the deployed position.

  Specifically, such a mechanism is provided in this room by fixing the support C side to the inner wall side of a room such as an automobile. By supporting something by the rotating body M at the unfolded position, the rotating body M at the unfolded position is used. Further, when the rotating body M is in the unfolded position, the support C is used in the unfolded position by storing something in the support C or taking out something stored in the support C. The More specifically, for example, when the rotating body M is configured as a hook body, the hook object can be hooked on the hook body as the rotating body M in the deployed position and the hook object can be supported by the hook body. . For example, when the rotating body M is configured as a lid body that closes the opening of the support C at the reference position and opens the opening at the deployed position, the lid as the rotating body M is rotated to the deployed position. The object to be stored can be stored in the support body C as a storage body through the opening opened in Fig. 2, and the stored storage object can be taken out.

  Further, the operating mechanism holds the state where the rotating body M is in the reference position so as to be releasable by a holding mechanism including a biasing member (a compression coil spring 15g for biasing a slider 15 described later). It has become.

  Then, the rotation of the rotating body M to a predetermined position causes the biasing member of the holding mechanism to accumulate energy, and the linkage with the holding mechanism is released to allow the rotating body M to rotate to the deployed position. When the rotator M reaches the deployed position, the urging force of the urging member returns the linkage with the holding mechanism, and the urging member M is returned to the reference position by this urging. .

  Thus, according to this operating mechanism, the rotating body M is expanded beyond the reference position by rotating to the predetermined position (the position in FIG. 4) (hereinafter, this rotating operation is referred to as a releasing operation). It can be rotated to a position. Further, the rotating body M that has reached the deployed position can be returned to the reference position by the urging force of the urging member of the holding mechanism, and can be stably positioned at the reference position until the next release operation is performed. .

  In this embodiment, the linkage between the rotating body M and the holding mechanism is restored after a lapse of a certain time after the rotating body M reaches the deployed position. As a result, in this embodiment, the return rotation toward the reference position of the rotating body M that has reached the unfolded position does not start immediately, and for example, the rotating body M is used for this fixed time. This makes it easy to perform work such as hooking something.

  Specifically, the holding mechanism includes a linkage gear 16 which will be described later. When the linkage gear 16 rotates to the deployed position of the rotary body M, a gear (a gear-like body 11f to be described later) provided to the rotary body M is provided. ), And after a lapse of a certain time after the rotating body M reaches the deployed position, the rotating body M is engaged with a gear provided on the rotating body M.

More specifically, such a holding mechanism is
A movable body (slider 15 to be described later) that is interlocked with the linkage gear 16 and is moved forward while accumulating in the urging member by rotating the rotating body M to a predetermined position;
An auxiliary urging member (a compression coil spring 18a of the auxiliary slider 18 described later) that accumulates by rotating the rotating body M from a reference position to a predetermined position opposite to the deployed position;
When the rotation operation to the predetermined position disengages the gear provided on the rotating body M and the linkage gear 16, and the rotation operation of the rotating body M is stopped at the predetermined position, the auxiliary biasing member is biased. The rotating body M is rotated toward the deployment position by
In addition, after a lapse of a certain time after the rotating body M reaches the unfolded position, the movable body moves backward by the biasing of the biasing member, and the linkage gear 16 meshes with the gear provided in the rotating body M, so that the rotating body M is in the reference position. It is designed to be rotated back to.

  The linkage gear 16 meshes with the gear provided to the rotating body M after a predetermined time has elapsed after the rotating body M reaches the deployed position by the braking means that applies a braking force to the movement of the moving body.

  In addition, the braking force that is applied to the movement of the moving body changes in the process of moving the moving body backward. Specifically, as will be described later, the braking means side gears are engaged with the two rotating body M side gears of the slider until the rotating body M reaches the predetermined intermediate position from the deployed position, and the reference position is determined from the predetermined intermediate position. Until this position, the meshing is lost and no braking force is applied to the movement of the moving body. Therefore, the return force of the rotating body M to the reference position is not affected by the braking force from the predetermined intermediate position. Yes.

  In addition, a biasing force in a direction of returning to the reference position is applied to the rotating body M on the deployment position side of the mechanism, and the returning rotation of the rotating body M is applied to the mechanism. Speed switching means is provided for differentiating the rotational speed from the unfolded position to the predetermined intermediate position and the rotational speed from the predetermined intermediate position to the reference position.

  When this operation is stopped after rotating the rotating body M to the unfolded position, the rotating body M starts to return to the reference position by the urging force, but the rotation speed is slowly increased to a predetermined intermediate position, for example. And can be performed faster than the predetermined intermediate position. As a result, while the rotating body M is slowly rotated, something is supported on the rotating body M, or something is placed in the supporting body C, or something is removed from the supporting body C. Can be taken out. When something is supported by the rotating body M as described above, the rotation return of the rotating body M is stopped by this, and when this support is stopped, the rotating body M is forcibly rotated to the reference position by the biasing. It can be made to return.

  In this embodiment, the case body 10 as the support body C has a box shape in which the front surface is opened and the opening edge of the opening portion 10a is formed in a substantially rectangular shape that is long in the vertical direction. It is configured. The case body 10 is provided with an outer casing 10b that goes around the opening 10a. The casing 10 is inserted into a mounting hole formed in an inner wall of a vehicle (not shown) or the like to a position where the outer casing 10b is caught by the mounting hole. As a result, it can be installed in such a room.

  On the other hand, the hook body 11 as the rotating body M has a substantially rectangular plate-like base portion 11a having a width and length substantially equal to the width of the open portion 10a of the case body 10, and one end side of the plate-like base portion 11a. Between the one end and the other end on one surface side of the plate-like base portion 11a, and a flange-like portion 11b that protrudes in a direction substantially perpendicular to the one surface and the protruding end is bent toward the other end side of the plate-like base portion 11a. The bearing part 11c formed in this is provided. The bearing portion 11c includes through holes 11e in the left and right plate portions 11d and 11d. In this example, the shaft 12 can be rotated around the shaft 12 by passing the shaft 12 through the through hole 11e of the bearing portion 11c of the hook body 11 through the through holes 10d formed in the left and right side plates 10c, 10c of the case body 10. The hook body 11 is assembled to the case body 10. At the reference position, the plate-like base portion 11a of the hook body 11 is positioned substantially on the same surface as the outer casing 10b of the case body 10, and closes the open portion 10a of the case body 10. (FIG. 2) On the other hand, the hook body 11 is tilted approximately 90 degrees forward from the reference position and positioned at the unfolded position. (FIG. 5) The other end of the hook body 11 thus turned downward is the inner surface of the left and right side plates 10c, 10c of the case body 10 and behind the through hole 10d through which the shaft 12 passes. A restricting portion 10g that abuts from is formed.

Further, in this example, the speed switching means includes two braking means side gears 13 and 13 that receive the action of the braking force of the braking means 27 on rotation, and a rotating body side gear that meshes with the braking means side gear 13 corresponding thereto. 14 and
The number of rotating body side gears 14 that mesh with the braking means side gear 13 changes before and after the return rotation of the rotating body M reaches a predetermined intermediate position.

  Thereby, in this example, the speed of return rotation of the rotating body M can be changed before and after reaching the predetermined intermediate position.

  In this example, the rotating body side gear 14 is configured by a rack 14a formed on a slider 15 described later, and before the return rotation of the rotating body M reaches a predetermined intermediate position, the two braking means side gears 13, 13 are provided. The racks 14a are engaged with each other, but after reaching the predetermined intermediate position, the braking means 27 does not engage with the gears in any rack 14a, and after the return rotation of the rotating body M reaches the predetermined intermediate position, the braking means side gear. The number of the rotor-side gears 14 that mesh with 13 is zero.

  In this example, the hook body 11 as the rotating body M includes a slider 15 that is supported by the case body 10 so as to be slidable in the front-rear direction, and a linkage gear 16 that is rotated in conjunction with the back-and-forth movement of the slider 15. The operation of the slider 15 is controlled by a compression coil spring 15g as a biasing means for biasing the slider 15 forward.

  The slider 15 includes a plate-like base 15a, an upper side plate 15b that protrudes upward from the left and right sides of the base 15a, and a lower side plate 15c that protrudes downward from the left and right sides of the base 15a. Grooves 15e extending along the front-rear direction are formed in the left and right sides of the slider 15, respectively, while the inner surfaces of the left and right side plates 10c, 10c of the case body 10 are respectively spaced from the top plate of the case body 10. A rail portion 10i extending in the front-rear direction with a space for accommodating the upper side of the slider 15 is formed on the slider 15, and the slider 15 is moved back and forth on the upper side of the case body 10 by placing the rail portion 10i in the groove 15e. It is paid as possible. Under the base 15a of the slider 15, a spring accommodating portion 15f that supports the front end of the spring by accommodating the spring front end of the compression coil spring 15g supported by the back plate 10j of the case body 10 is provided. The slider 15g always receives a biasing force directed forward by the spring 15g.

  The linking gear 16 has a fan-like plate shape, the arc-shaped portion thereof is provided with teeth, and the case body 10 has a shaft 16a having an axis line along the axis in the left-right direction at the main portion behind the rotating assembly portion of the hook body 11. It is combined to be rotatable. The linkage gear 16 is provided on each of the left and right sides. The left and right plate portions 11d and 11d of the bearing portion 11c of the hook body 11 are respectively gear-like bodies 11f having teeth on the plate edge portions. In this example, the right gear-like body 11f of the hook body 11 is meshed with the right linkage gear 16, and the left-side gear-like body 11f of the hook body 11 is meshed with the left linkage gear 16. It has become. Further, the upper side of the left and right linkage gears 16 is accommodated between the left and right lower side plates 15 c of the slider 15. Through holes 16b are formed on the upper ends of the left and right linkage gears 16, respectively, and a long hole 15d extending in the vertical direction is formed on the front end side of the lower side plate 15c of the slider 15. The slider 15 and the linkage gear 16 are linked to each other through the shaft 17 to the 16 through holes 16b and the elongated holes 15d of the lower side plate 15c of the slider 15. The end of the shaft 17 is received in a watermark groove 10e formed in the left and right side plates 10c, 10c of the case body 10 along a circular arc centered on the axis of the linkage gear 16.

  In this example, the overturning rotation of the hook body 11 at the reference position toward the unfolded position causes the slider 15 to retreat against the urging force of the urging means via the linkage gear 16. Thus, such overturning rotation is prevented, and the state in which the hook body 11 is in the reference position is stably maintained. (FIG. 2) At this time, the shaft 17 is at the front end of the watermark groove 10e, and further advancement of the slider 15 is prevented.

  In this example, an auxiliary slider 18 in the form of a block is supported between the left and right upper side plates 15b of the slider 15 so as to be movable back and forth. The auxiliary slider 18 is also always urged forward by a compression coil spring 18a as auxiliary urging means, and protrudes forward from the front edge of the upper side plate 15b of the slider 15 when the hook body 11 is at the reference position. Although it abuts against the hook-shaped portion 11b of the hook body 11 at the reference position (FIG. 2), the biasing force of the auxiliary slider 18 is smaller than the biasing force of the slider 15, and the hook body 11 is at the reference position. The auxiliary slider 18 does not disturb the state.

  When the upper end side of the hook body 11 at the reference position is pushed backward, the hook-like portion 11b is first pushed against the front end of the auxiliary slider 18 to be pushed against the bias (FIG. 3). This flange-shaped portion 11b presses against the front end of the upper side plate 15b, and the slider 15 is pushed backward against the bias. (FIG. 4 / Release Operation) Accordingly, the linkage gear 16 is also rotated.

  In the example shown in the figure, the gear-like body 11f is rotated in the clockwise direction in FIG. 2 by this release operation, and the linkage gear 16 meshing with the gear-like body 11f is rotated in the counterclockwise direction in FIG. The shaft 17 of the gear 16 is positioned on the lower end side of the long hole 15d of the slider 15, and the lower end side of the long hole 15d of the slider 15 has a margin for allowing the shaft 17 to escape in the rotating direction of the linkage gear 16 at this time. Thus, the counterclockwise rotation of the linkage gear 16 before the slider 15 starts to move backward is allowed. Further, since the backward movement of the slider 15 causes the rotation of the linkage gear 16 in the clockwise direction in FIG. 3, it is necessary to release the meshing between the gear-like body 11f and the linkage gear 16. In the illustrated example, the watermark groove 10e is configured so that the groove width is increased from the rear end 10e 'toward the front end thereof, whereby the slider 15 is pushed in and the shaft 16a of the linkage gear 16 is simultaneously generated. Is moved from the front end 10f ′ to the rear end of the shaft hole 10f to disengage the gear-like portion 11f and the linkage gear 16 and allow the slider 15 to retreat.

  In this example, when the slider 15 is retracted as described above, a later-described rack 14a of the slider 15 and the braking means side gear 13 are engaged with each other. Due to this engagement, even if the hook body 11 is stopped from being pushed, the slider 15 is not moved forward by urging. Therefore, when the hook body 11 is stopped from being pushed, the auxiliary slider 18 is moved forward by the urging to move the upper end side of the hook body 11 forward. The hook body 11 is turned over to the deployed position beyond the reference position and beyond the predetermined intermediate position. (FIG. 5) When the slider 15 is advanced from this state to a position where the shaft 16a of the linkage gear 16 is positioned at the front end of the shaft hole 10f, the linkage gear 16 and the gear-like body 11f of the hook body 11 are engaged again. (FIG. 6) The hook body 11 in the unfolded position is further rotated back toward the reference position by the slider 15 that is advanced by urging.

  In this example, a rack 14a as a rotating body side gear 14 is formed so as to be continuous along the front-rear direction at the base of the upper side plate 15b of the slider 15 and on the outer sides of the left and right upper side plates 15b. Has been.

  On the other hand, in this example, the two braking means 19 and 19 are each configured as a so-called rotary damper that includes a stator body 19a and a rotor body (not shown) and is configured to give resistance to the rotation of the rotor body. Yes. The application of such resistance to the rotor body can be ensured by, for example, enclosing a viscous fluid such as silicone oil in the stator body 19a. The braking means side gear 13 is provided on the braking means 19 side with its rotation center fixed to the outer end of the rotor body.

  In this example, the stator body 19a is fixed to one of the left and right side plates 10c, 10c of the case body 10 so that the braking means side gear 13 is positioned in the case body 10, and one of the braking means 19 is provided in the case body 10. In addition, the stator body 19a is fixed to the other of the left and right side plates 10c, 10c of the case body 10 so that the braking means side gear 13 is positioned in the case body 10, and the other of the braking means 27 is provided in the case body 10. I am letting. The right rack 14a of the slider 15 meshes with the lower end of the right brake means side gear 13 while the hook body 11 is returned and rotated from the deployed position to the predetermined intermediate position, and the left brake means side gear 13 is engaged. The rack 14a on the left side of the slider 15 is engaged with the lower end of the slider 15 while the hook body 11 is returned and rotated from the deployed position to the predetermined intermediate position. The total length of the rack 14a of the slider 15 is shorter than the moving dimension of the slider 15, and after the hook body 11 reaches a predetermined intermediate position, the position of the non-rack 14a of the slider 15 is below the lower end of the braking means side gear 13. It is supposed to be located.

  Thereby, in this example, before the return rotation of the rotating body M reaches the predetermined intermediate position, the braking force of the two braking means 19 and 19 is simultaneously applied to the rotating body M to rotate the return body M. On the other hand, after the return rotation of the rotating body M reaches a predetermined intermediate position, the braking force of the two braking means 19 and 19 is not applied to the rotating body M so that the rotating body M returns. The rotation is accelerated.
