Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotary operating device, and in particular to an operating device for a seat height or counter-adjustment device in a motor vehicle or the like.

[Conventional technology]

For example, some driver's seats in automobiles or the like have a height or an angle that can be changed depending on the physique or preference of the driver.

In the known automobile seat constructed in this manner, the hinge arms provided at the front and rear of the seat frame are pivotally supported by legs fixed to the seat support provided on the floor side of the vehicle body, and act on the hinge arms. The seat frame is raised and lowered by a pivoting motion, and an operating device is operably connected to the hinge arm, and the height is adjusted by operating the operating device. A friction brake device is used as a locking mechanism to disable lifting and lowering operations.

As this friction brake device, Japanese Patent Application Laid-Open No. 59-29827
There is something disclosed in the issue. That is, this brake drum is fixed to the seat frame, and includes a lever plate fixed to a drive shaft supported by a center hole in the bottom wall of the drum, and a driven shaft rotatably connected to the drive shaft. An anchor is installed on the drive shaft, and the drive shaft is fixed with serrations.
・Fix the handle and apply mK! A connecting member of the seat elevating mechanism is attached to the riIIn (1+).A pair of guides is disposed between the lever plate and the bunker, and both guides are pressed against the [31] surface of the brake drum. The braking spring has contact parts that are connected to both ends of the brake spring and come into contact with the hanger to stop the movement of the lever plate when the lever plate is stopped, and a cam part that engages with the lever plate when the lever plate is rotated. At the beginning of the lever plate's rotation, the lever plate is swung due to engagement between the cam part and the lever plate, releases contact with the hanger, and a gap is formed between the lever plate and the hanger, and this gap causes the brake spring to contract in diameter. The pressing force against the inner circumferential surface of the brake drum is weakened, the friction brake is released, and the driven body 11Ql can be rotated.

[Problem to be solved by the invention] In this brake device, the driven shaft is friction-locked by the braking spring coming into pressure contact with the internal surface of the brake drum (because it is a 1+ff configuration, a shock is applied to the seat). When a large downward load acts on the driven shaft and rotational force is applied to the driven shaft, the !ul motion springs off.

There is a risk that the entire inside of the ram will slide, causing the seat to fall below the set height, and ffi! Since braking is performed by expanding and contracting the winding diameter of the I-motion spring, it has been difficult to accurately position the seat at a desired height.

In view of this, the present invention locks the driven shaft by engaging the shaft, and unlocks the shaft by extending and sliding the handle.
To provide a rotation operating device which is configured to reliably lock a seat height adjustment device, etc. that is linked to the ejection movement 4111, and also allows smooth unlocking and rotation operations. The technical challenge is to do so.

[Failure to solve the problem]

In order to solve the above-mentioned technical problem, the present invention fixes a gear 0) coaxially with the driven shaft αa to the frame via a mounting bracket 0, and corresponds to the driven shaft (6) K gear Qll. A pace bracket (11) is inserted and fixed therein, and a lock gear (19) that meshes with the gear G1) is rotatably attached to the inner surface of this base bracket (01) at a location distant from the insertion part of the driven shaft (2). At the same time, a guide bracket α→ is coaxially and rotatably attached to the insertion part of the driven shaft 02 on the outer surface side of the R-s bracket α℃, and a pin αη protruding from the lock gear 09 is attached to the guide plate care 1toOG.
The base bracket 0]) is equipped with a telescopically slidable handle α3, and this handle 03 and the guide bracket αQ are used as interlocking members to form a wire assembly. It is designed to move through the motion.

[Effect]

The above technical means works as follows.

When the handle 09 is contracted and stored in the pace bracket αη, the lock gear 0 → is engaged with the gear 0]), and the base bracket 0]) is relative to the gear OD, that is, the driven lll1l (6) is relative to the frame. Locked.

Therefore, when the handle (13) is extended and slid, the wire assembly (as a movement member of the guide bracket (IG)
2) Through the rotation 1, the pin 0 which is engaged with the deformed elongated hole 0 frame of the guide placent αG.
7'l in a direction away from lock gear 0Q to release the lock, and in this state, grasp the extended and slidable handle (2) and pull it up or push it down (from K to the driven shaft) is rotated together with the pace bracket αη, and an adjustment mechanism connected thereto is driven.

FIG. 5 shows the state in which the rotation operating device is attached to the cushion frame portion of the same seat.

The rotation control device 00 shown in FIGS. 1 to 3 is composed of a rotation side member and a fixed side member, and the 0°C axis 1] is a driven device connected to a height adjustment device to be described later. This base bracket α]) is a pace bracket as a movable side member fixed to the shaft 02, and is formed in the shape of a box with a frame integrally formed on the periphery of the outer vessel surface, and the upper edge has a guide tube part (), 1a)'i is provided, and an outer cylinder (13a) and an inner cylinder (13b) (, (in a telescopic manner, yl (alternately) and handle α3 are accommodated in a telescopic manner, and approximately in the center is a The bushes α and p are penetrated and fixed to the driven part B1+02 by serrations.

On the inner surface of this base bracket α℃, a lock gear (1!3) that engages with a fixed gear, which will be described later, is pivotally attached to a part remote from the fixed part with the driven shaft 02, and on the outer surface, a lock gear (1! 3) that engages with a fixed gear is pivotally mounted. The lock gear 0Q and the guide bracket Qυ are held together by the protruding pin αη of the lock gear αυ using the guide bracket (LE).
Place the pace-bracket α℃ into the deformed long hole α formed at i.
This is done by inserting and engaging through two id grooves αe formed in the guide bracket αe, and a roller bin holder is provided protruding from the tip of the guide bracket αe, so that the outer edge side of the lock gear 09, that is, the side facing the meshing portion Guide bracket α along the edge
It is configured so that it comes into sliding contact with the rotation of Q.

The guide bracket αQ is the outer cylinder (1) of the handle α3.
3a) via a wire assembly. That is, a projecting piece He protrudes from the outer cylinder (13a) of the handle a3, and the projecting piece (4 ) K e y (c) A long hole ring of the required length (2
), and the wire of the wire assembly (c) is connected to the pin (20a) that is integrated with the roller pin that protrudes from the tip of the guide bracket αQ, and the ring wire fixed to the other end of the wire unsempu IJ f2n. The guide bracket αQ is connected to the handle (to) by engaging the middle part of the part (21a) with the wound part of the guide pin (a) protruding from the outer fII11 surface of the base bracket α. .

In addition, the guide plaque (H) has a spring (c) stretched between the raised piece (16a) protruding from the rear edge side and the lower gauze of the pace bracket l-111, so that it is always in the direction of the lock gear (one on the ear 0]). Bias it so that it rotates.

(31) is a gear as a fixing member, and is fixed coaxially with the above-mentioned driven shaft (6) via G2 f (brake socket for mounting on a fixed body such as a cushion frame), that is, the gear (31)
An insertion hole (31g) for the driven shaft (6) is drilled in the center of the hole, and an insertion hole (32a) is also drilled in the mounting bracket O, and both holes (31g) (32g) 't ``In the matched state, connect the gear G11 and the bracket 3 to the rivet 03, and fix the mounting bracket 1-(3) to the fixed body.

Next, to explain the operation of the rotary operation device 00 consisting of a movable member and a fixed member as described above, when it is contracted and stored in the guide cylinder part (lla) of the /S handle α3 or the base bracket αη, the outer cylinder The protruding piece (A) of (13a) is in the retracted position, and the pin (C) protruding from it corresponds to the rear end of the long hole ring (C) of the wire assembly IJ (21). Assembly (c) K has no traction force,
As a result of this striking, the guide bracket α0 is rotated downward by the spring (c), and the lock gear αυ, which is engaged through the pin αη, is pushed as the roller pin is rolled into contact with the outer θ side of the tip. In this state, it is engaged with the gear 0υ as a fixed member (the state shown in Figure 1), and the base bracket (111
is non-rotatable and the driven shaft (6) is in a locking shape.

When the handle α3 is pulled out halfway from this state, the inner cylinder (13b) is pulled out, the outer cylinder (13a) is also pulled out a small amount, and the protrusion (a) is also moved forward, but this amount of movement Since the pin is small, the pin simply moves within the hollow of the long hole ring (c) of the wire assembly (c) to the front end, so no traction force acts on the wire assembly f2υ, and therefore the guide bracket αG And the lock gear C1 is not activated, and the long-lock condition of +fa11- is maintained (FIG. 3A).

Then, when you pull out the handle α3 to the farthest point, the outer cylinder (13a
) is also pulled out a predetermined length, and the protruding piece (a) moves forward, so that the wire assembly Qυ is pulled through the pin (c) and pulled up against the biasing force of the guide bracket αqt spring (c). Rotate it. The upward rotating gear 05 of this guide bracket αQ is rearward, that is, gear 0, because the pin αη is pressed by the edge of the deformed elongated hole Qe.
The driven shaft (8) is rotated in the direction away from the shaft (8) to disengage the gear (3) and unlock the driven shaft (8).

In this state, by pushing down the pulled handle (13) until it is completely pulled up, the driven shaft α2 rotates via the pace bracket 01, and the driven shaft 11j (
The adjustment mechanism connected to 19 is actuated.

When the driven shaft (6) has been rotated by the desired amount in this way and you release your hand from the handle α3, the handle (19) is contracted by the deflection force of the sliding ring (A) and the guide cylinder part (II) is
a) is housed within. That is, the inner cylinder (13b) is the outer cylinder (13
a) Since the outer cylinder (13a) is not inserted into the guide cylinder part (I
1a) and is stored, and this action causes the protrusion (a) to move rearward and release the traction of the wire assembly QB via the bottle (c). Therefore, the guide bracket αQ The biasing force of the spring (c) causes the lock gear (19
is rotated forward by the engagement of pin 07) and farm hole 0→, gear (31) K is engaged, and the driven shaft (6) is locked by the rotational force described above, and the adjustment mechanism is in its operating state. Retained.

To further change the operating state 4 or to return to the original state, the driven shaft (6) is unlocked and rotated as described above.
