The present invention relates to a handle device for rotating the correcting shaft connected to this by the forward and reverse rotation of the handle used for opening and closing the door, and for performing the door opening and correcting. At the time of locking, the handle can be removed from the visibility shaft, and the lock handle device is automatically stopped with respect to the seating body of the visibility shaft by removing the handle, and the stop is soon released by the insertion of the handle. Is about

As a lock handle device of this kind, what is indicated in Japanese Unexamined Patent Application Publication No. 49-21503 has already been known, but in this conventional device, a plate spring is used as a member for stopping the visibility shaft relative to the seat body, and this plate is fixed to the seat body side. The spring is put into the handle recessed groove on the side of the visibility shaft, and the visibility shaft is stopped.

However, in the stop member consisting of a leaf spring, when the spring is fatigued by long-term use, the stop member cannot sustain the rotational bias of the visibility shaft given by the weight of the stop plate and the locking rod mounted on the end of the visibility shaft. It has escaped from the steering wheel recess groove.

In addition, since the actuating protrusion 8 was a simple one, the unlocking of the lock handle device is not limited to the corresponding key handle 7, and the locking release device is also released by inserting a suitable plate and correcting effect. Was not expected and had safety difficulties.

Therefore, the object of the present invention is that the stop function of the visual axis to the seat body can be effectively maintained forever without deterioration by prolonged use and can only be solved by a specific key handle corresponding to the device body. An object of the present invention is to provide a lock handle device having no high visibility effect.

Referring to the embodiment shown in the following, the lock handle device is a locking body (3) fixed to the door panel (1) and the viewing body (3) and the seating body (2) rotatably supported by the seating body (2) Rear end surface of the connecting flange 5 protruding from the attachment flange 4 protruding at the front end of the coupling flange 4 and the front end of the visibility shaft 3 from the connecting flange 5 and the insertion opening 33 provided with the insertion opening 33. The operation handle 8 is attached to the handle engaging groove 6 of 5a) and is not rotatable to the key handle 7 which is inserted and detached freely, and the recessed part 9 of the front end surface 4a of the attachment flange 4. The jammer 13 and the jammer 17 are installed in the handle recess groove 6, and the jammer 14 and the cutout 15 are notched in the insertion hole 33. On the outer ridge 47 of the front end face 4a of the attachment flange 4 and on the actuating protrusions 8 of the key handle 7 on the obstructions 13 and 14 and the obstruction ridge 17. Corresponding grooves 18, 19 and groove 21 and And installing a penetration balji 20 corresponding to the cut-out recess (15, 16).

In the illustrated embodiment, a projection 48 is provided on the rear end surface 4a of the attachment flange 4, and the hole 22 corresponding to the projection 48 and the seating body 2 is formed on the rear end surface 4a. After engaging the sheet 23 made of the installed elastic member, the attachment flange 4 is attached to the door panel 1 provided with fixing holes 24 and 25 corresponding to the seating body 2 and the projection 48. By fitting the spring washer 26 to the outer circumferential threaded portion of the seating body 2 and screwing the nut 27, the body portion is fixed to the writing panel 1.

In addition, the attachment flange 4 and the connection flange 5 are attached to each other by fitting the locking shaft 3 into the shaft hole 28 of the seating body 2 and into the engaging groove 29 provided at the bottom of the tip shaft 3a. By engaging the engagement band 30, it is impossible to detach.

In addition, the stop plate 32 is fitted to the tip angular shaft portion 3a of the visibility shaft 3 to be fixed by the bolt 31.

The stopper plate 32 is provided with an attachment hole 34 of the locking rod.

Also, in order to be able to adapt the lock handle device to any of the left and right rotation stop types, the projection 35 of the rear end face 5a of the connecting flange is symmetrically with respect to the shaft hole 28 of the front end face 4a of the attachment flange. The angle of rotation of the visibility shaft 3 is regulated by engaging one of the formed arc grooves 36 and 37, and the cutouts 16 of the outer ridge portion 47 are placed on the upper and lower portions of the attachment flange 4 by one. Pair is installed. The recessed portion 9 of the attachment flange 4 has a so-called platelet-shaped cross-sectional shape in which left and right sides are cut out, and the shaft hole 28 is opened at the center portion thereof.

The stop member 10 on the rear plate also has a shape coinciding with the recessed part 9, and since the handle gripping groove 6 is installed at the left and right sides and the insertion port 33 side with the correcting shaft 3 in the center, the protruding portion Three 12 are provided. The insertion hole 38 of the visibility shaft 3 is formed in the middle of these projections 12, and the stop member 10 is slidable in the longitudinal direction of the visibility shaft 3. A cutout 45 is provided in a part of the insertion hole 38 and the cutout 45 engages with the engaging projection 46 provided on the correcting shaft 3 at the time of correcting to accurately stop the stop member 10 in a non-rotational state. It is stopped.

In addition, the front face 4a of the attachment flange and the rear end face 5a of the connecting flange abut against each other so that the plate thickness of the operating protrusion 8 substantially coincides with the depth of the handle gripping groove 6.

In this lock handle device, when the stop plate 14 is engaged with the collection part not shown on the side of the box body and the door panel 1 is in the closed lock position, the recess 9 and the handle release groove 6 are matched with each other. It is in one position.

Therefore, when the key handle 7 is detached from the connecting flange 5, the stop member 10 slid forward by the bias of the compression coil spring 11, and the front protrusion 12 is moved to the handle recess groove 6. In this way, the visibility shaft 3 is prevented from rotating and stopped with respect to the seat body 2.

Next, when the key handle 7 is inserted into the handle catching groove 6 from the insertion hole 33 of the connecting flange 5, the grooves 18 and 19 are first raised in the jamming protrusions 13 and 14. The grooves 21 correspond to the recesses, respectively, and the lasting protrusions 20 correspond to the notch recesses 15 and 16, and the insertion is completed when the retaining protrusions 20 enter the inside from the notch recesses 16, respectively. .

Thus, the tip of the working protrusion 8 presses the inclined cam 12a of the protrusion 12, so that the stop member 10 stands behind the compression coil spring 11 while supporting the protrusion 12 so that the protrusion 12 is recessed. 9) Immerse yourself in.

As a result, the fixation shaft 3 can be rotated by turning the key hand 7 engaged with the coupling flange 5 by the stop of the seat body 2.

In addition, when the rotation operation is performed, the matching positions of the cutout portions 15 of the connecting flange 5 and the cutout portions 16 of the attachment flange 4 are displaced, so that the cutout portions 15 are formed on the outer ridge portion of the attachment flange 4 ( The key handle 7 is not detached from the lock handle device because it is closed by the door 47 and the support protrusion 20 abuts against the outer circumferential bumper 47.

In addition, a groove 39 is provided in the main side surface 4c of the attachment flange 4, and a large packing 40 made of an elastic member is inserted in the groove 39, and the main side surface of the visibility shaft 3 ( A groove 41 is also provided in 3b) to insert the small packing 42 made of the resilient member into the groove 41, so that the packings 40 and 42 are respectively connected to the inner wall 43 of the circumferential wall 43 of the connecting flange 5, respectively. Since it comes into contact with the inner wall of the seat body 2a, a constant frictional force can be obtained and a constant rotational angle can be maintained at the time when the force applied during the rotation operation of the key handle 7 is removed, and it does not return to the correct state unintentionally. In addition, since the guide member 44 made of an elastic member is provided at the bottom of the operation protrusion 8, the door panel 1 is not damaged when the key handle 7 is removed.

As described above, the lock handle device of the present invention is different from the conventional lock handle device in which the leaf spring is directly used as the stop member, and there is no attenuation and deterioration of the stop function even by long-term use, and the visibility shaft 3 is not rotated accurately. Stability is further improved because it can be held still, has excellent stability of operation and reliability, and can only be solved by a key handle having a specific shape corresponding to the device body.
