Abstract

PROBLEM TO BE SOLVED: To provide a fixing structure of a door handle that enables an engagement mechanism provided on the door handle to be easily assembled and enables a square core to be easily and securely inserted into the door handle.SOLUTION: A door handle 1 is composed of a pair of handles 2, 3 that are disposed on opposite sides of a door and fixed to each other using a square core 5. The handle 2 comprises: a holding member 12; a locking plate 11 having a square hole; a compression spring 10; and a holding pin 13 that restricts the movement of the locking plate 11. The locking plate 11, on which the holding pin 13 is held through a line contact, reciprocates between a locking posture and a releasing posture and is energized by the compression spring 10 to the holding posture side. When a force for inserting the square core 5 is applied on the handle 2, the locking plate 11 moves from the locking posture to the releasing posture, and the square core 5 is inserted into the square hole. When the force is released, the compression spring 10 holds the locking plate 11 in the locking posture, preventing the square core 5 from moving.

Description

  The present invention relates to a door handle connection structure in a latch lock or the like.

  A latch lock mainly provided on a door such as a hinged door includes a latch that can engage the door with the door frame and release the engaged state, and a lock case including the latch. That is, the lock case is provided with a mechanism in which the latch protrudes and retracts from the lock case, and the mechanism is designed to be interlocked with the operation of the door handle.

  Specifically, in the latch lock, a square core having a substantially square cross section is inserted into a square hole of a hub provided in the lock case, and door handles are respectively attached to both ends of the square core. The door handle and the latch can be mechanically integrated.

  By the way, conventionally, when fixing a pair of door handles to a door, a square core is inserted into one door handle in advance and fixed with connecting means such as a pin, and the square core in this state is fixed to the lock case. It is inserted into the square hole of the hub, the end of the square core is inserted into the other door handle, and the door handle is fixed using connecting means such as screws.

  However, in this type of door handle connection structure, if the connecting means for fixing the door handle is unexpectedly dropped, the door handle itself may drop from the door, and the door cannot be opened and closed with respect to the door frame. There's a problem.

For this reason, when fixing a pair of door handles to the door, it is necessary to press both door handles against the door, but either door handle is closed in a situation where the door is closed with respect to the door frame. If the door is dropped from the door, the other door handle cannot be pressed against the door, and the door handle cannot be fixed to the door. That is, in a sealed space that is difficult to communicate with the outside, when a situation occurs in which the door handle falls off, it becomes impossible to escape from the sealed space, and in some cases, a dangerous state occurs.
There is also a desire to avoid fixing the door handle using connecting means such as screws because it is troublesome in the first place.

  Therefore, Patent Document 1 discloses a technique that can fix a door handle without using a connecting means such as a screw. That is, Patent Document 1 discloses a square core in which a locking plate having a square hole is formed inside one door handle of a pair of door handles, and a groove is formed in the square hole of the locking plate. Is inserted, and the square core is engaged with the locking plate to fix the door handle. Specifically, inside the door handle, the locking plate is disposed between the compression spring and the locking unit, and when the locking plate is inclined at a certain angle from the standby position, the square core is a square hole of the locking plate. The square core is engaged with the locking plate as it approaches the standby position.

JP 2001-254538 A

  However, in the door handle connection structure of Patent Document 1, the locking plate may not smoothly tilt from the standby position to the appropriate tilt angle, and in that case, the square core is not inserted into the square hole of the locking plate. Despite the omission of the connecting means, there was a complaint that it took extra time to fix the door handle as a result.

  Specifically, in Patent Document 1, an engagement groove is formed on the upper side of the door handle where the locking plate is disposed, and movement of the upper side of the locking plate is limited by the engagement groove. However, the lower side of the locking plate is configured to be swingable, but the upper side of the locking plate and the engaging groove are configured such that the surfaces are in contact with each other to restrict movement, and therefore the locking plate is not swung. Low freedom of movement. Thereby, in patent document 1, it became easy to receive to the influence of the variation in manufacture, and it became difficult for the latching board to incline to an appropriate inclination angle depending on manufactured goods.

  Moreover, in patent document 1, it is also the structure which assembles each member (locking plate, compression spring, locking unit) which forms the engaging mechanism which engages a square core substantially inside a door handle. That is, the production is troublesome and becomes a factor of increasing the production cost.

  Therefore, an object of the present invention is to provide a door handle connection structure in which an engagement mechanism provided on a door handle can be easily assembled and a square core can be easily and reliably inserted into the door handle.

  In order to solve the above-described problem, the invention according to claim 1 is a door handle connection structure that integrally connects to a pair of door handles arranged at positions sandwiching a door using a square core, At least one door handle has a holding means for holding the square core so as not to rotate relatively, a locking plate provided with a square hole through which the square core can be inserted, and a biasing means for biasing the locking plate And a restricting means that is fixed to the holding means and restricts movement of the locking plate, and the locking plate is held in a point or line contact with the limiting means and is substantially perpendicular to the axial direction of the square core. Between the locking posture and a release posture inclined from the locking posture, with the holding means as a reference, and the biasing means biases the locking plate toward the locking posture. When the force to insert the square core is applied to the door handle, the locking plate changes from the locked position to the released position. When the square core is inserted into the square hole of the latch plate and the force is released, the latch plate is held in the latch posture by the urging means to prevent the square core from moving. The door handle connection structure.

In the door handle connection structure of the present invention, the restricting means holds the locking plate in point or line contact, and the locking plate swings between the locking posture and the releasing posture on the basis of the holding portion. Therefore, compared with the prior art, the degree of freedom of rocking of the locking plate is high. That is, since the area where the restricting means can come into contact with the locking plate is reduced, the operation is not easily restricted when swinging. Thereby, since the influence of manufacturing variation can be reduced, the problem that the locking plate is difficult to be inclined at an appropriate inclination angle is suppressed. That is, according to the present invention, even if there are variations due to manufactured products, the square core can be easily and reliably inserted and fixed in the square holes of the locking plate.
Further, in the present invention, the locking plate can be held by the limiting means fixed to the holding means, and therefore, for example, an assembly of the holding means and the locking plate in advance can be arranged on the door handle. Therefore, manufacturing can be facilitated. That is, unlike the prior art, the work of assembling the locking plate or the like inside the door handle is omitted, so that the work efficiency is increased and the manufacturing cost can be reduced.

  In the invention according to claim 2, the restricting means is a U-shaped pin, one end side forming the pin is fixed to the holding means, and the movement of the locking plate is restricted on the other end side. The door handle connection structure according to claim 1, wherein the door handle connection structure is provided.

  According to such a configuration, since the shape of the limiting means is simple, attachment to the holding means is facilitated, and the manufacturing cost is not significantly increased.

  According to a third aspect of the present invention, the locking plate is provided with an inclined portion at least on the side held by the restricting means, and abuts against the restricting means in the release posture. Or it is the connection structure of the door handle of 2.

  According to such a configuration, since the locking plate is provided with the inclined portion that comes into contact with the restricting means when being in the release posture, the locking plate is easily inclined when the square core is pressed against it.

  In the door handle connection structure according to the present invention, the locking plate is held in a point or line contact by the limiting means and is allowed to swing by limiting the movement, so that the locking plate can be swung freely. . Thereby, even if there is variation due to manufactured products, the square core can be easily and reliably inserted into the square hole of the locking plate and fixed. Furthermore, in the door handle connection structure of the present invention, since the restricting means is fixed to the holding means, manufacturing labor can be saved and manufacturing costs can be reduced.

That is, the door handle 1 is inserted into the pair of handles 2 and 3 and the hub square hole 47 of the hub 48 provided in the lock case 50 and transmits the operation of the pair of handles 2 and 3 to the latch 49. 5 and an elastic member 6 held by the square core 5.

  In the present embodiment, the door handle 1 can be easily attached to the hinged door 55. That is, in the present embodiment, the structure of the handle 2 located on the left side in FIG. 1 is different from the structure of the handle 3 located on the right side. Specifically, the handle 2 located on the left side of FIG. 1 includes a main body 2a, a compression spring (biasing means) 10, a locking plate 11, and a holding member that holds the square core 5 so as not to relatively rotate. (Holding means) 12 and a holding pin (restricting means) 13 for restricting the movement of the locking plate 11 are provided, and the handle 3 located on the right side in FIG. 1 has a main body 3a.

First, the structure of the handle 2 located on the left side of FIG. 1 will be described.
As shown in FIG. 3, the main body portion 2 a of the handle 2 has an “L” shape, and is divided into a grip portion 20 and a connection portion 21 with an L-shaped bent portion as a boundary. On the connection part 21 side, an end part is opened, and a fitting space 14 into which the holding member 12 and the like are inserted is formed from the end part. The insertion space 14 has a relatively small region 14a having a circular cross-sectional shape and a relatively large region 14b having a circular cross-sectional shape, and is in a communication relationship with each other.
In addition, two through holes 28 for connection are provided on the side wall of the connection portion 21 so as to communicate the outside and the insertion space 14 (only one is shown). The two connection through holes 28 are arranged in series on the same circumference, and are arranged 90 degrees apart from each other with the center of the circle as a reference. As shown in FIG. 10, connecting means 69 such as a roll-shaped pin is inserted into the connecting through hole 28.
On the lower side surface, an operation opening 27 for operating a locking plate 11 described later is provided. The operation opening 27 is a substantially rectangular opening, and a flathead screwdriver or the like can be inserted therein.
The compression spring 10 is the same as that known in the art.

As shown in FIG. 4A, the locking plate 11 is a substantially square plate-like member, and a locking square hole 22 through which the square core 5 can be inserted is provided at a position including the center. That is, the locking plate 11 can be said to be a rectangular frame member. As shown in FIG. 4B, the pair of opening edge portions 23 and 24 forming the locking square hole 22 are inclined, and the inclination directions thereof are parallel to each other.
In addition, the locking plate 11 is formed with inclined portions 29 and 30 which are inclined in the same direction as the opening edge portions 23 and 24 at the pair of edge portions 25 and 26, respectively. Further, the inclined portions 29 and 30 formed at the respective edge portions 25 and 26 are in a positional relationship in which they are reversed in the thickness direction of the locking plate 11 with respect to the center of the locking plate 11.

When the eye is moved to the holding member 12, the holding member 12 is a cylindrical member as shown in FIGS. 3 and 5, and a through-hole 31 through which a later-described square core 5 that penetrates in the axial direction is inserted. And a pin holding portion 32 for holding a part of a holding pin 13 to be described later is provided on the side wall.
The through hole 31 has a substantially square cross-sectional shape, and its cross-sectional area is designed to be substantially the same as or slightly larger than the cross-sectional area perpendicular to the axial direction of the square core 5.

The pin holding portion 32 is located on one end side in the axial direction of the holding member 12, and the groove portion 40 formed from the end portion side toward the center side, and the center of the cross section of the holding member 12 from the bottom portion of the groove portion 40. It is comprised by the hole part 41 drilled toward.
The groove portion 40 is a portion formed by being surrounded by a protruding wall 42 protruding outward from the outer surface of the holding member 12. That is, the bottom surface of the groove portion 40 is the outer surface of the holding member 12 excluding the protruding wall 42. The hole 41 is a hole having a depth that does not reach the through hole 31.
The groove 40 and the hole 41 are in a relationship of communicating in an L shape (not shown in detail).
Note that the protruding wall 42 extends from one end side of the holding member 12 to an intermediate portion in the axial direction.

  In addition, at one end portion of the side surface of the holding member 12, there are two projecting portions 43 that can hold the locking plate 11. Specifically, the two projecting portions 43 are in a positional relationship that is 180 degrees apart from the center of the through hole 31, and the inner portions of the projecting portions 43 face each other. Further, the separation distance between the inner portions of the two overhang portions 43 is set to be the same as or slightly larger than the width of the left and right (FIG. 4) of the locking plate 11. That is, the overhanging portion 43 is a portion that holds the locking plate 11 so as to sandwich it.

  Further, three connecting through-holes 35 drilled toward the center of the cross section of the holding member 12 are provided on the side wall of the holding member 12 in the middle in the axial direction (only one is shown). The connection through holes 35 are arranged in series on the same circumference, and the other connection through holes 35 are separated by 90 degrees in the circumferential direction with reference to one connection through hole 35. Are arranged.

  When the holding member 12 is arranged in the fitting space 14 of the main body 2a, any two of the three connecting through holes 35 of the holding member 12 communicate with the connecting through hole 28 of the main body 2a. It is arranged at the position to do. That is, as shown in FIG. 10, connecting means 69 such as a roll-shaped pin is inserted into the connecting through hole 35 of the holding member 12 and the connecting through hole 28 of the main body 2a, and the holding member 12 12 is fixed so as not to move and operate relative to the main body 2a.

  The holding pin 13 is a linear member having a “U” shape, and holds the locking plate 11 so as to be swingable with respect to the holding member 12. The holding pin 13 has a circular cross-sectional shape, and has an outer diameter that can fit into the groove 40 and the hole 41 of the holding member 12.

The assembly structure of each member of the handle 2 in this embodiment will be described as follows.
That is, as shown in FIGS. 1 and 10, the locking plate 11 and the holding member 12 are arranged such that the locking angular hole 22 of the locking plate 11 and the through hole 31 of the holding member 12 communicate with each other, In this state, it is inserted into the insertion space 14 (insertion portion) of the connection portion 21 of the handle 2. Specifically, each member is located in the region 14b of the insertion space 14, and the compression spring 10, the locking plate 11, and the holding member 12 are arranged in this order from the region 14a side. In addition, since the one end side of the compression spring 10 is contact | abutting to the step part formed in the boundary of the area | region 14a and the area | region 14b, even if it presses on the area | region 14a side, the compression spring 10 itself does not move.

  Further, the holding pin 13 is disposed so as to straddle the locking plate 11 and the holding member 12, and holds the locking plate 11 so as to be swingable with respect to the holding member 12. That is, one end side of the holding pin 13 is held in the hole 41 of the pin holding part 32 in the holding member 12, and the locking plate 11 is held on the other end side. More specifically, the holding pin 13 holds the line of the inclined portion 29 side (holding portion side) of the locking plate 11 and enables other portions to swing. In this state, the compression spring 10 urges the locking plate 11 toward the holding member 12.

Then, in a state where the connection through hole 28 of the connection portion 21 of the handle 2 and the connection through hole 35 of the holding member 12 are in communication with each other, as shown in FIG. The connecting means 69 is inserted through the cable.
The locking plate 11 is disposed in the operation opening 27 located on the lower side surface of the connection portion 21 so that the swinging side of the locking plate 11 (the side facing the holding portion side) is positioned.

Next, the configuration of the handle 3 will be described.
As shown in FIG. 6, the main body 3 a of the handle 3 has an “L” shape similar to the main body 2 a of the handle 2. It is divided into 64. On the connection part 64 side, an end part is opened, and a fitting space 65 into which the square core 5 and the like are inserted is formed from the end part. The insertion space 65 is a region having a substantially rectangular cross-sectional shape.

  Further, two through holes 67 for connection are provided on the side wall of the connection portion 64 to communicate the outside with the insertion space 65. The two through holes 67 for connection are arranged in series on the same circumference, and are in a positional relationship that is 180 degrees apart from each other in the circumferential direction. Note that a connecting means 58 such as a roll-shaped pin is inserted through the connecting through hole 67.

Then, the structure of the square core 5 and the elastic member 6 is demonstrated.
First, the configuration of the square core 5 will be described.
As shown in FIG. 7, the square core 5 is a prismatic member having a substantially quadrangular cross section, and intersects the corner notches 60 and 61 formed near one end with the axial direction of the square core 5. A connecting through hole 62 penetrating in the above-mentioned direction and a holding groove 59 for holding an elastic member 6 described later are provided.
The corner cutout portions 60 and 61 are portions where the corners of the square core 5 are partially cut off. The corner cutout portion 61 is provided near the one end portion, and the corner cutout portion 60 is a corner cutout portion. It is provided closer to the center than 61. The respective corner notches 60 and 61 are arranged in series on substantially the same circumference.

  The connection through hole 62 is a through hole formed so as to penetrate any one pair of side surfaces, and is disposed between the corner cutout portion 60 and the corner cutout portion 61. Specifically, the connection through hole 62 is designed at a position where it can communicate with the connection through hole 67 provided in the main body 3 a of the handle 3. That is, when the square core 5 is inserted into the fitting space 65 of the main body portion 3a, the connection through hole 62 of the square core 5 is in a positional relationship to be in communication with the connection through hole 67 of the main body portion 3a. When the connecting means 58 such as a roll-shaped pin is inserted into the connecting through holes 67 and 62, the square core 5 can be fixed so as not to move relative to the main body 3a.

  The holding groove 59 is a groove formed from one vertex toward the center when the cross section of the square core 5 is used as a reference, and as shown in FIG. It is a groove formed toward (the end opposite to the end where the corner notches 60 and 61 are located). In addition, the holding groove 59 is provided with an inclined portion 76 whose bottom portion is gently inclined on the end side located at the axial direction intermediate portion of the square core 5. The inclined portion 76 has an upward slope toward the middle side of the square core 5 and has a more gently rounded shape. The groove width of the holding groove 59 is equal to or greater than the thickness of the elastic member 6.

The configuration of the elastic member 6 will be described.
The elastic member 6 is a member formed in a shape in which any part is deformed or displaced when an external force is applied. That is, as shown in FIGS. 7 and 9, the elastic member 6 of the present embodiment has a substantially “S” shape in a side view, and has an arcuate exposed portion 70 and a holding groove 59 of the square core 5. The elastic member 6 against the square core 5, the groove abutting portions 71, 72 that abut against the bottom portion of the first member, the square hole pressing exposed portion 73 that presses the through hole 31 of the holding member 12 or the hub angular hole 47 of the hub 48, and And a fixing portion 74 to be fixed.

  Specifically, based on FIG. 9, the exposed portion 70 is a portion that is partially exposed from the holding groove 59 and is also a portion that connects the groove contact portion 71 and the groove contact portion 72. That is, the external force applied to the exposed portion 70 is transmitted from the groove contact portion 71 and the groove contact portion 72 to the square core 5. As a result, the groove contact portions 71 and 72 receive a reaction force from the square core 5.

Further, the square hole pressing exposed portion 73 is disposed at a position facing the exposed portion 70 with the groove contact portion 72 as a reference. That is, the square hole pressing and exposing portion 73 is a position where the square hole pressing and exposing portion 73 is deformed or displaced by the reaction force generated against the elastic member 6.
The fixing portion 74 is a projection-like portion located between the exposed portion 70 and the square hole pressing exposed portion 73, and as shown in FIG. A movement restricting portion 57 that restricts movement relative to the square core 5 is formed.

  Therefore, in the present embodiment, when the elastic member 6 is fitted and integrated in the holding groove 59 of the square core 5, the groove contact portion 71 of the elastic member 6 is arranged so as to be located on the end side of the square core 5, The groove abutting portion 72 is disposed so as to be positioned on the intermediate side of the square core 5. At this time, as shown in FIG. 9, the groove abutting portions 71 and 72 of the elastic member 6 abut on the bottom of the holding groove 59, and the exposed portion 70 and the square hole pressing exposed portion 73 of the elastic member 6 are separated from the holding groove 59. Exposed. In this embodiment, since the holding grooves 59 are formed on the diagonal line of the square core 5, it can be said that the elastic member 6 is also arranged on the diagonal line of the square core 5.

  Further, the movement restricting portion 57 is formed by caulking the holding groove 59 of the square core 5 at a portion corresponding to the fixing portion 74 of the elastic member 6. The movement restricting portion 57 restricts the elastic member 6 from moving relative to the square core 5.

Next, the attachment procedure of the door handle 1 of this embodiment is demonstrated.
Here, in the following description, it is assumed that the lock case 50 in which the hub 48 is installed is attached to the hinged door 55 in advance.

First, an integrated body of the square core 5 and the elastic member 6 (hereinafter referred to as a square core composite body 15) is integrated with the handle 3. That is, as shown in FIG. 11 (a), the corner notches 60 and 61 side end portions of the square core 5 are inserted into the fitting space 65 of the handle 3, and the connection means 58 and the square core 5 are connected by the connection means 58. To fix.
Thereafter, the other end side of the square core 5 is inserted into the hub square hole 47 of the lock case 50. At this time, as shown in FIG. 11 (b), the square hole pressing exposed portion 73 is pushed into the holding groove 59 of the square core 5 by the hub square hole 47, and exposed by the reaction force received from the bottom of the holding groove 59. The portion 70 is displaced in the direction exposed from the holding groove 59.

  And the handle | steering-wheel 2 is inserted with respect to the square core composite body 15 of the state. That is, the square core complex 15 is inserted through the through hole 31 of the holding member 12 of the handle 2. Then, as shown in FIG. 12A, the square core complex 15 reaches the locking plate 11 in the locking posture that communicates with the through hole 31 of the holding member 12. When the square core composite 15 is further pushed into the handle 2, the locking plate 11 swings away from the holding member 12 based on the position of the holding pin 13.

  That is, the front end of the square core composite 15 abuts against the upper and lower opening edges 23 and 24 of the locking plate 11, and the force pressing the locking plate 11 overcomes the urging force of the compression spring 10. It moves to the compression spring 10 side. At this time, the locking plate 11 is held in linear contact with the holding pin 13, but since the area to be held is smaller than that in the surface contact, the locking plate 11 is held in this embodiment. Easy to swing while.

  Thereby, as shown in FIG. 13, the inclined surfaces of the opening edge portions 23 and 24 of the locking plate 11 can be parallel to the axial direction of the through hole 31 of the holding member 12 (release posture). In addition, if the releasing posture in this embodiment is demonstrated from another angle, the inclination part 29 by the side of the latching plate 11 hold | maintained at the holding pin 13 contact | abuts the holding pin 13, and the attitude | position by which rocking | fluctuation is restrict | limited. It is.

  When the locking plate 11 is in the release posture, the square core 5 can be inserted into the locking square hole 22, so that the square core 5 moves smoothly into the handle 2. That is, as shown in FIG. 12B, the square core complex 15 can be inserted into the locking square hole 22 by inclining the locking plate 11. When the external force on the handle 2 is released at a desired position, the locking plate 11 is tilted toward the locking posture by the urging force of the compression spring 10, so that the square core 5 and the locking plate 11 are brought into a close contact state. 5 becomes difficult to move relative to the locking plate 11. In other words, the handle 2 is unlikely to fall off the square core 5.

  At this time, as shown in FIG. 11C, the exposed portion 70 is pushed into the holding groove 59 of the square core 5 by the through hole 31, thereby generating a reaction force in the groove contact portions 71 and 72. The square hole pressing and exposing portion 73 moves in the exposing direction. On the other hand, the square hole press exposed portion 73 is pressed against the hub square hole 47. That is, when the square hole pressing and exposing portion 73 moves in the exposure direction, the connection between the square core 5 and the hub 48 becomes strong, and rattling is prevented. Furthermore, since the exposed portion 70 is pressed against the holding member 12, the connection between the square core 5 and the handle 2 becomes stronger. Since the elastic member 6 is disposed on the diagonal line of the square core 5, it does not rotate around the axis of the square core 5 in the hub square hole 47.

  As described above, in this embodiment, since the locking plate 11 that can fix the square core 5 to the handle 2 is held in line contact with the pin-shaped holding pin 13, the locking plate 11 is not swung. High freedom of movement. That is, in this embodiment, even if there are variations in manufactured products, the influence can be reduced, so that the locking plate 11 can be inclined at an appropriate angle. Therefore, according to the present invention, by using the holding pin 13, it is possible to provide a door handle fixing structure in which the square core 5 can be easily and reliably inserted into the handle 2 and there is no trouble in mounting.

  According to the present invention, since the holding pin 13 and the locking plate 11 can be assembled to the holding member 12 outside the main body 2a, the manufacturing efficiency of the handle 2 can be improved. . Thereby, manufacturing cost can be suppressed.

  Furthermore, in this embodiment, by inserting the square core complex 15 into the handle 2, the square hole pressing exposed portion 73 of the elastic member 6 presses the inner wall of the hub rectangular hole 47, and further, the exposed portion of the elastic member 6. Since 70 presses the inner wall of the holding member 12, the square core 5 can be easily fixed to the hub 48 and the square core 5 can be easily fixed to the handle 2. Even in the handle 2, the elastic member 6 is arranged on the diagonal line of the through hole 31, so that it does not rotate around the axis of the square core 5.

  Here, the positional relationship of each member of the door handle 1 of the present embodiment when attached to the hinged door 55 will be additionally described.

  As shown in FIG. 2, the door handle 1 according to the present embodiment includes a pair of handles 2 and 3 disposed at a position sandwiching the hinged door 55, and the square core complex 15 inserted through the hub angular hole 47 of the hinged door 55. The handle 3 is attached to the end on the side where the corner notches 60 and 61 are located, and the handle 2 is attached to the end on the side where the holding groove 59 of the square core composite 15 is located.

  As shown in FIGS. 3 and 6, the handle 3 and the square core 5 are in a positional relationship in which the connection means 58 is inserted into the connection through hole 67 and the connection through hole 62 of the square core 5. The handle 2 and the square core 5 are in a positional relationship in which a part of the elastic member 6 of the square core composite 15 presses the inner wall of the holding member 12 outward. That is, in the handle 2, the exposed portion 70, the square hole pressing exposed portion 73, and the groove contact portions 71 and 72 of the elastic member 6 are deformed or displaced from each other by inserting the square core complex 15. It is related.

Further, due to this positional relationship, the elastic member 6 also presses the inner wall of the hub square hole 47, so that the square core 5 is prevented from rattling against the hub 48. In addition, about the specific positional relationship of the square core 5, the elastic member 6, and the handles 2 and 3, since it is as having mentioned above, it abbreviate | omits.
Further, the operation opening 27 of the connection portion 21 of the handle 2 is located at the edge portion on the swinging side of the locking plate 11, and is arranged to swing within the range of the operation opening 27.

  In the above-described embodiment, the shape of the handles 2 and 3 is an “L” shape, but the present invention is not limited to this, and a handle having a substantially cylindrical shape may be used.

In the above-described embodiment, as a restricting means for restricting the movement of the locking plate 11, a configuration in which the locking plate 11 is held in line contact by using a linear member having a “U” shape. Although shown, the present invention is not limited to this, and both ends of the U-shape may be further bent 90 degrees to hold the locking plate 11 in point contact. In short, the limiting means may be any configuration that can hold the locking plate 11 by line or point contact.
As described above, the restricting unit need not be a separate member, and may be integrated with the holding member 12.

  In the above-described embodiment, the square core 5 and the elastic member 6 are used to fix the handles 2 and 3. However, the present invention is not limited to this, and is a technique similar to that of the prior art. It may be a configuration of only.
