Description

  The present invention relates to a door capable of a natural handle operation that does not cause a sense of incongruity in opening and closing.

  Conventionally, as a handle for opening and closing a door provided at an opening of a building or the like, a so-called push-pull handle that retracts a latch bolt by operating the handle in the same direction as the door opening when the door is opened is known. It has been.

  The push-pull handle is provided with a handle portion that swings in a direction close to the door surface (= pressing side) on the pressing side of the door that is opened by pressing. The handle side that swings in the direction away from the surface of the door (= the pull side) is provided on the surface on the pulling side that is released by the above, and the swinging of these handle portions, that is, “push” or “pull”. The latch bolt is retracted by the operation "and the door can be opened.

  However, a door having a push-pull handle as described above is particularly useful when the door is opened when there is no door closer or the like for controlling the door to be opened and closed suddenly. On the opening side, when the person performing the opening operation pushes the handle part vigorously, the latch bolt quickly retracts and the engagement with the receiving seat is released instantly, thereby opening the door vigorously. There was a problem that the person who opened the door could turn forward with the door in the direction of operation, or could collapse seriously.

  The door of the cited reference 1 is known as what solves this. As shown in FIG. 14, the door (1) is engaged with the engagement hole (6) of the door frame (3) by a latch bolt (51) which is provided on the door (1) side and which can freely move back and forth. The closed state of the door (1) is maintained, and the door stop (5) side is the door (1) in the pressing release direction, and the latch bolt (51) is retracted by pulling the door (1) toward the door end side. A handle portion (50) for unlocking is provided.

  This handle portion (50) is disposed on the door end side of the door (1), and the base end located on the door end side is a shaft support portion (50b), and extends from the shaft support portion (50b) toward the suspension base. With the lever part (50a), the latch bolt (51) is retracted by the `` pull operation '' to move the lever part (50a) away from the door surface and engage with the engagement hole (6) of the door frame (3) In this state, when the surface (1m) on the pressing release side of the door (1) is pushed (or the surface (1n) on the pulling release side of the door (1) is pulled), the door (1) opens.

  In such a door (1), the release of the latch bolt (51) is referred to as `` pulling '' the lever part (50a) on the surface (1m) on the pressing release side of the door (1) that causes the above problems. When the person who performs the door opening operation vigorously performs the handle operation as described above, when the door (1) is suddenly opened, the posture is excessively urged in the opening direction, and the front is the operation direction. It is possible to prevent the user from falling forward or falling down seriously.

Japanese Patent Laying-Open No. 2004-3187 (FIG. 5)

  However, such a handle portion (50) opens the door (1) only by operating the lever portion (50a). Therefore, when the door (1) is opened as shown in FIGS. The force (F) applied to the operating surface (50c) of the lever part (50a) touched by the fingertip is continuously applied while changing the direction in accordance with the rotation of the lever part (50a) and the subsequent rotation of the door (1). (In other words, the direction between the angle (α) between the virtual surface (S) parallel to the door (1) and the operation surface (50c) of the lever part (50a) around the operation point of the fingertip) Continue to apply force toward (Q) and change the direction of applying force with the same fingertip that is being operated as the door (1) moves in the opening direction) until you get used to the operation It was difficult to use.

  The present invention has been made to solve such problems, and an object thereof is to develop a safe door using a door handle that can be easily opened by pulling a lever portion.

The invention described in claim 1 (FIG. 5)

The handle body (9) pivotally attached to the fulcrum shaft (12) near the door end side, and the handle body (9) extends from the handle body (9) to the suspender (2b) side, and a finger other than the thumb is applied. lever portion (10) and de-configured handle portion (8),
Is mounted on the handle portion (8), de an actuating lever that causes the lock release by sinking operation of the door body (1a) or al spaced directions of pulling operation at latch bolt (21) of the lever portion (10) (14) Configured,
Pushing operation surface (9a) of the handle main body (9) and the door main body (1a) which are provided in a direction along the axial direction of the fulcrum shaft (12) and on which the thumb is applied when the lever portion (10) is gripped. The door (1) is characterized in that an angle of intersection (γ) with the surface of the door is formed at an acute angle.

  The invention described in claim 2 (FIG. 4) further restricts the pushing operation surface (9a) of the handle body (9). The lever projecting surface (9b) of the handle body (9) and the handle body (9) The intersection angle (δ) with the pushing operation surface (9a) of 9) is 30 ° to 70 °.

  According to the invention described in claim 3 that depends on claim 1 or 2, the push operation surface (9a) of the handle body (9) protrudes outward in the longitudinal direction or the direction along the longitudinal direction and the axial direction of the fulcrum shaft. It is curved, and an intersection angle (γ) between a tangent line (T) at a certain point (W) of the push operation surface (9a) and the surface of the door (1) is formed at an acute angle. Here, the door handle device (7) has a pressure release side and a tension release side, and the pressure release side is represented by (7a).

  Here, although it is the pushing operation surface (9a) of the handle body (9) provided in the direction along the axial direction of the fulcrum shaft (12), the embodiment 1 of FIGS. 4 and 5 and the embodiments of FIGS. 2 and 3, the handle body (9) has a bag-like shape with an opening on the mounting plate (13) side, a substantially triangular outer wall (9g), and a lever protruding surface (9b) on which the lever portion (10) protrudes. (In the first embodiment of FIGS. 4 and 5, in the second and third embodiments of FIGS. 7 to 9, the opening edge (9 c at the lever side end of the opening edge (9 c) of the handle body (9)) ) And a push operation surface (9a) which is formed so as to be inclined downward toward the door (1) where the thumb is applied when the lever portion (10) is gripped. ). Of these surfaces, only the push operation surface (9a) is provided in the direction along the axial direction as shown by arrows in FIGS. Note that the push operation surface (9a) is only defined as a surface in the direction along the axial direction in relation to other surfaces as described above, and does not define the shape of the surface. As is clear from the whole, (a) the entire surface is flat, (b) a curved surface obtained by cutting a part of the cylinder that is gently convex along the longitudinal direction, or (c) the convex surface that is loosely projected in the longitudinal and axial directions. A curved spherical surface was included, and the second and third embodiments were added to make this a clear shape.

The straight line that defines the angle of intersection (γ) between the push operation surface (9a) and the surface of the door (1) is the push operation surface when the push operation surface (9a) is a flat surface as in (a) above. (9a) is a straight line (R), but when the push operation surface (9a) is (b) or (c), the straight line is a surface constituting the push operation surface (9a) (the push operation surface (9a )
In the case where there are irregularities, these are not included in the push operation surface (9a). ) Is a tangent line (T) drawn in the direction of the lever portion (10) at any point (W) constituting the push operation surface (9a). Push operation surface (9a)
As described above, in any case, it is a surface on which the thumb is applied when the lever portion (10) is gripped, and is a surface formed so as to be inclined downward so as to approach the surface of the door (1) toward the tip.

  The boundary between the push operation surface 9a and the lever portion 10 in the second and third embodiments is the handle where the push operation surface 9a is the contact portion of the thumb. This means a virtual surface (M) formed at a right angle to the opening edge (9c) at the lever part side end of the opening edge (9c) of the main body (9). The intersection (m) is shown in the handle portion (8).

  According to the handle portion (8) of the door handle device (7a) according to claim 1, the surface which is provided in a direction along the axial direction of the fulcrum shaft (12) and on which the thumb is applied when the lever portion (10) is gripped. The angle of intersection (γ) between the push operation surface (9a) of the handle body (9) and the surface of the door (1) is formed at an acute angle.In other words, when the lever (10) is gripped, Since it is formed on the hanging surface so as to approach the surface of the door (1) as it goes to the tip, as shown in FIG. When the handle body (9) is pushed with the thumb together with the `` pull operation '' for placing the thumb on the push operation surface (9a) of the handle body (9) and separating the lever portion (10) from the door surface, the handle portion (8 ) Rotates around the fulcrum shaft (12), the latch bolt (21) is detached from the door frame (3) by the operating lever (14), and the door (1) is released.

At this time, since the handle portion (8) rotates around the fulcrum shaft (12), the handle portion (8) performs pulling and pushing operations while rotating in the same rotation direction (right rotation). Become. In this case, the thumb direction becomes naturally positive to put the power of time to open the door (1) it means that face forward, the door (1) natural in the press operation on the thumb of the handle body (9) The door can be opened and opened easily, and depending on the handle operation as in the past, the latch bolt (21) is suddenly disengaged, and at the same time the door (1) is suddenly opened and the operator's posture is momentum. It is possible to prevent the operation direction from being turned forward or falling down.

  As in the invention described in claim 2, the angle of intersection (δ) between the lever projecting surface (9b) of the handle body (9) and the pushing operation surface (9a) of the handle body (9) is 30 ° to 70 °. By doing so, when the thumb sticks out with the fingers held, the angle between the index finger of the gripped fist and the protruding thumb is 30 ° to 70 °, and the lever part (10) is gripped with four fingers. The angle when the thumb sticks out on the push operation surface (9a) of the handle body (9) is the same as that of the handle body (9). The door (1) can be easily opened and closed, and the handle (1) can be opened and closed smoothly.

  The invention according to claim 3 further clarifies 2 and 3 of the embodiment included in claim 1, and the push operation surface (9a) is a loose curved surface as in (b) (c) above. Or in such a case, the intersection angle (γ) between the tangent (T) at a certain point (W) of the push operation surface (9a) and the surface of the door (1) is an acute angle. This is the case. Also in this case, the push operation surface (9a) on which the thumb is applied when the lever portion (10) is gripped is formed so as to be inclined downward so as to approach the surface of the door (1) toward the tip.

  The present invention will be described below with reference to the illustrated embodiments. The door (1) is hinged to a door frame (3) fixed to the opening (K) via a support fitting (4) such as a hinge. A door lock body (20) having a latch bolt (21) that protrudes and appears on the door end side (2a) of the door (1) to lock and release the door (1) with respect to the door frame (3). ), And when the door (1) closes the opening (K), the latch bolt (21) protrudes from the door end side surface (2a) and is provided on the door frame (3). The engagement hole (6) is inserted and the door (1) is kept closed.

  The locking mechanism of the door lock body (20) is not particularly limited as long as the engagement state is released by each operation of the door handle device (7) mounted on both sides of the door (1). However, for example, those shown in FIGS. 10 to 11 can be used.

  The same door handle device (7) is mounted on both sides of the door (1) as shown in FIG. 1, but here the door (1) has a problem with the pressure release side, so the door (1) The door handle device (7a) on the pressing release side, that is, the first embodiment shown in FIGS. FIG. 7 shows the second and third embodiments that are slightly different in structure from the first embodiment. For convenience of drawing, it is described that a door handle device (7) that is different in the vertical direction is attached. The upper door handle device (7) is functionally the same as the lower side, so it is mounted on the pull-in side in the figure, but can be used on the push-in side. Of course, in the figure, it is free to attach the same thing up and down or what has the same function in function although the structure is different as shown in the figure.

  The casing (28) of the door lock body (20) is fitted in a recess opened on the door end side end surface (2a) of the door (1), and the mounting plate (29) of the casing (28) is fitted on the door end side. It is attached to the end face (2a). The mounting plate (29) is provided with a latch hole (29a) for the protrusion and immersion of the latch bolt (21), and the latch bolt (21) is stored in accordance with the latch hole (29a). A latch hold part (24) provided with a storage hole (24a) is provided in contact with the mounting plate (29) in the casing (28).

  Further, the latch hold portion (24) is provided with a guide hole (24b) communicating with the storage hole (24a), and a latch head (for engaging / disengaging with the engagement hole (6) of the latch bolt (21)). A neck portion (21b) protruding from 21a) is slidably inserted.

  Then, a thin engagement suspension portion (21c) that is swingably engaged from a neck portion (21b) to a swing arm (22), which will be described later, protrudes, and a latch bolt (21) is provided in the storage hole (24a). A latch spring (25) that presses and urges in the protruding direction is housed.

  Behind the latch bolt (21) is provided a swing arm (22) suspended so as to be swingable by a rotating shaft (22a), and an engaging portion (22b) provided at the lower end thereof. ) Can be swung by the engagement suspension part (21c) of the latch bolt (21) .For example, the head part (21d) having a larger diameter than the engagement suspension part (21c) provided on the engagement suspension part (21c) is engaged. It is inserted through the through hole (22h) provided in the joint (22b), swings the neck while engaging with the swing of the swing arm (22), and allows the latch bolt (21) to move linearly. ing.

  An extending portion (22d) extending from the side surface of the swing arm (22) obliquely upward and rearward (upper right side in FIG. 7) has an engagement operating portion ( A swing engaged part (22c) with which 23b) is engaged is provided perpendicular to the extension part (22d).

  An operating portion (23) is disposed below the inner portion of the casing (28), and the engaging operating portion (23b), which is the upper end portion of the operating portion (23), is configured to swing the swing arm (22). The actuating part (23) is engaged between the spring engaging part (23a) and the casing (28) provided at the lower end of the actuating part (23) and is engaged with the driven part (22c) from the door end side. An actuating spring (30) that presses and urges the door toward the door end is provided.

  An operating window (27) is formed in the center of the operating portion (23), and an operating claw (14b) that is a tip portion of an operating lever (14) of the door handle device (7) described later. Each is to be inserted. The casing (28) is also provided with an operating lever insertion hole (26) corresponding to the operating window (27) (see FIGS. 4, 10, and 11).

  As shown in FIGS. 1 to 6 (first embodiment), the door handle device (7a) on the release side includes a mounting plate (13), a handle portion (8), and an operating lever (14). Has been.

  The mounting plate (13) is a tray-like thing that is embedded in the surface of the door (1), and is located near the center of the door (i.e., the lever protruding surface (9b) of the main body (13e)). A pair of bearing arms (13a) protrudes from the end of the bearing, and a fulcrum shaft (12) is installed between the bearing arms (13a).

  Then, a finger receiving recess (13b) is provided on the suspension base side with the bearing arm (13a) as a boundary, and an operating part lever storage recess (13c) is provided on the body part (13e) on the door end side. Is formed. The operating portion lever storage recess (13c) is provided with a through window (13d) in accordance with the operating portion lever insertion through hole (26) provided in the casing (28).

  As shown in FIG. 3, the finger receiving recess (13b) is formed with a half-moon-shaped digging around the lever portion (10) of the handle portion (8), as shown in FIG. It is dug according to the part (10). Since the finger receiving recess (13b) is provided, when the lever (10) is gripped by the second to fifth fingers, the second to fifth fingers are stored in the finger receiving recess (13b). The protrusion dimension (H) of the lever portion (10) can be reduced. In this way, by reducing the protrusion dimension (H) of the lever part (10), it is possible to reduce the clothes from being caught on the lever part (10) and the body from colliding.

  Further, when the shape of the finger receiving recess (13b) is made into a half-moon shape as shown in FIG. 3 described above, the portion facing the lever portion (10) is deepest, so that the rod-like lever portion (2nd to 5th fingers) Combined with the fact that the finger shape (fist shape) when holding 10) is curved, the lever part (10) must be operated with the second to fifth fingers. Intuitive and easy to understand.

  As shown in FIGS. 12 to 13, the handle portion (8) shown in the first embodiment is formed into a bag shape from the center portion closer to the door tip side to the door tip side, and the handle main body (9 (This is, as mentioned above, a substantially triangular outer wall (9g), a lever projecting surface (9b) on which the lever (10) is projected, and a push operation where the thumb is applied when holding the lever (10)) And a lever portion (10) projecting from a lever projecting surface (9b) which is a rear end surface of the handle body (9). 9) A fulcrum shaft (12) is swingably attached to a bearing arm (13a) provided in the interior.

  When the lever portion (10) is gripped by four fingers, the remaining thumb is in the direction along the side surface of the handle body (9), that is, the axial direction of the fulcrum shaft (12) (the arrow direction in FIGS. 12 and 13). The surface of the handle body 9 is pushed by a thumb (9a) of the handle body 9 by the thumb.

  The push operation surface (9a) is (b) the push operation surface when (a) the push operation surface (9a) is entirely a flat surface (not limited to this, for example, see FIG. 5). When the direction along the axial direction of the fulcrum shaft (12) of (9a) is a straight line, and the longitudinal direction perpendicular to this is a loosely convex arc (not limited to this, for example, FIGS. (C) The push operation surface (9a) as a whole may have a convex spherical shape loosely swollen outward (not limited to this, for example, see FIGS. 8 and 9), and (b) (c ) Is subtracted from any point (W) on the push operation surface (9a) (not including irregular irregularities and indentations formed on the surface as will be described later). This is the angle with the tangent (T). Therefore, in any case, the inclination angle (γ) of the handle body (9) (= the angle between the push operation surface (9a) of the handle body (9) and the surface of the door (1)) is the same as that of the latch bolt (21). It is set so that an acute angle is maintained when the engaged state is released (and naturally before the engagement is released). In other words, it is a surface on which the thumb is applied when the lever portion (10) is gripped, and is formed to be inclined downward so as to approach the surface of the door (1) toward the tip.

  With this setting, it is easy to push the push operation surface (9a) with the thumb while the latch bolt (21) is disengaged, and the push operation surface (9a) of the handle body (9) can be pushed with the thumb. The door can be opened by pushing.

  In this case, the push operation surface (9a) of the handle body (9) is provided with, for example, a plurality of ridges (15) or lateral grooves as shown in FIG. 12, or a recess (FIG. 13) into which the thumb fits. 16) may be provided. (However, parts such as the ridge (15) or the lateral groove and the depression (16) are naturally not included in the push operation surface (9a), and the push operation surface (9a) in the same part is not included in the handle body (9). This means a “virtual surface” along the outer surface.) When such a thing is provided, when pushing the door (1) open, the push operation surface (9a) of the handle body (9) Even if it is the first time to operate, it is easy to understand intuitively, and the convex strip (15) etc. also works as a non-slip, so the thumb presses the operating surface (9a) It is possible to facilitate the operation.

  In the lever portion (10), the lever projecting surface (9b) is formed substantially perpendicular to the opening edge (9c) of the handle body (9), and this lever projecting surface (9b) and the handle body ( It is desirable that the angle (δ) formed by the pressing operation surface (9a) of 9) is 70 ° to 30 °. In such an angle range, although there are individual differences, it is close to the angle that the thumb and the second finger naturally form when the hand is opened (= the angle that is not intentionally widened or narrowed), and has a rod shape. When the lever portion (10) is gripped by the second finger to the fifth finger, the thumb naturally follows the push operation surface (9a) of the handle body (9), so that the push operation is easy.

  The lever projecting surface (9b) has a function as a side operation surface that can attach the side portion of the second finger on the first finger side in a state where the lever portion (10) is gripped. When the door is opened by the function as the side operation surface, a force can be applied to the lever projecting surface (9b), which is the side operation surface, in the side of the thumb side of the second finger in the door opening direction.

  When not operated (state shown in FIG. 4), the angle (β) formed by the surface of the door (1) and the lever projecting surface (9b) which is the side operation surface is preferably an obtuse angle close to a right angle. If the angle (β) is an obtuse angle close to a right angle, the side of the thumb side of the second finger is easy to touch the lever protruding surface (9b), which is the side operation surface, and force is applied in the direction to open the door (1). Easy to add.

  Further, the intersection angle (ε) on the fulcrum shaft (12) side at the intersection point P on the extension line of the pushing surface (9a) of the handle body (9) and the outer surface of the lever portion (10) is an obtuse angle close to 180 °. It is formed. When the entire outer surface of the push operation surface (9a) or the handle main body (9) is gently curved outward, the aforementioned angle (ε) is a point on the push operation surface (9a) or the outer surface. This is the angle with the tangent (T) in (W).

  Inside the handle body (9), a pair of front and rear holding arm portions (18a) (18b) for holding the operating lever (14) are installed. The actuating lever (14) is an L-shaped plate. The base end (14k) of the lever body (14a) is rotatably supported by the fulcrum shaft (12), and the center and tip of the lever body (14a) are pin (17a). ) (17b) is attached to the holding arm (18a) (18b), and its operating claw (14b) protrudes from the handle body (9) and is inserted into the operating window (27) of the operating unit (23). .

  As shown in FIG. 4, the overall shape of the lever portion (10) in the present embodiment is loosely curved outward and approaches the door (1), and the mounting plate (13) with the lever end attached to the door surface. As long as the shape is close to the door, or any other shape that can be hooked and gripped with a finger, the shape may extend substantially parallel to the door surface.

  As shown in FIG. 4, when the shape is close to the door (1) and the end of the lever is close to the mounting plate (13), the lever of the lever (10) can be used not only when opening and closing, but also when operating. Since the end portion does not protrude toward the operator side, it is possible to reduce the catch of clothes and the body from hitting the lever end portion.

  The lever portion (10) has a rod shape that can be grasped by the second finger to the fifth finger, and its cross section is not particularly limited, such as a circular shape or a polygonal shape. A shape in which the surface on the side facing the mounting plate (13) is a curved surface is preferable. If this surface is a curved surface, it feels good because it matches the shape of the finger bent to hold it.

  Thus, when the closed door (1) is opened from the pressure release surface (1m), as shown in FIG. 5, four fingers other than the thumb are hooked on the lever portion (10) of the door handle device (7). Hold the thumb, place the thumb on the push operation surface (9a) of the handle body (9), and simultaneously pull the lever (10) with the four fingers grasped on the push operation surface (9a) of the handle body (9). Press with your thumb. Then, the handle part (8) rotates around the fulcrum shaft (12), and the operating lever (14) hooks the operating part (23) in accordance with this movement, and retracts so that the operating spring (30) is compressed. (See FIGS. 10 and 11).

  Then, due to this retreat, the swing arm (22) is rotated rearward, and the engaging portion (22b) provided at the lower end of the swing arm (22) moves the head (21d) of the latch bolt (21). Pull the latch bolt (21) linearly back. Thereby, the latch bolt (21) is detached from the door frame (3), and the door (1) is released.

  At this time, as described above, since the intersection angle (γ) between the push operation surface (9a) of the handle body (9) and the surface of the door (1) is formed at an acute angle, the thumb pushes against the handle body (9). The door (1) can naturally open the door (1) by the operation, and the door opening operation is easy, and there is no such thing as the front turning or falling down during the conventional operation.

  In the first embodiment, the intersection angle (δ) between the lever projecting surface (9b) of the handle body (9) and the push operation surface (9a) of the handle body (9) is 30 ° to 70 °. When the lever portion (10) is gripped, the thumb naturally comes to the push operation surface (9a), and the operation method can be understood intuitively.

  After opening the door (1), when the hand is released from the handle part (8), the latch bolt (21) protrudes by the elastic force of the latch spring (25) and the operating spring (30), and the handle part (8) 1) Turn to the side and return.

  Next, second and third embodiments of the present invention will be described with reference to FIGS. A part of the comparison with the first embodiment has already been described. In this case, unlike the first embodiment, the finger receiving recess (13b) is not provided, and the inside of the handle portion (8) is formed in an arc shape matching the side surface of the index finger when the lever portion (10) is gripped (of course. The mounting plate (13) does not have a finger receiving recess (13b), and is a shallow dish-shaped body portion where the operating portion lever receiving recess (13c) is formed. (13e) only. Of course, a finger receiving recess (13b) may be provided.

  The opening shape of the operating part lever storage recess (13c) of the mounting plate (13) is such that the entire opening edge (9c) of the handle body (9) fits, and a pair of bearing arms (13a) from the bottom. And a fulcrum shaft (12) is installed between the bearing arms (13a) as in the first embodiment. Similarly, the fulcrum hole (14j) of the base end (14k) of the operating lever (14) is fitted into the fulcrum shaft (12) and is supported rotatably.

(18d) (18e) (18f) is attached to the handle part (8) and its operating claw (14b) protrudes from the handle body (9) to the operating window (27) of the swing arm (22). Has been inserted.

  Here, the support structure of the pins (17a) and (17b) is functionally the same, but is different from that of the first embodiment, and this point is described in the lower diagram of FIG. 7 and FIG. A brief explanation follows. In the second embodiment, one side surface of the handle body (9) is cut out in a substantially triangular shape, and a lid portion (9e) having the same shape and a known fitting structure is attached to the cutout portion (9d). It has become.

  Holding arm holes (18c) (18d) (18e) for holding the pins (17a) (17b) on the inner side surface of the lid (9e) and the inner side surface of the handle body (9) facing the inner side surface (18f) is recessed. A collar (14i) that is inserted through at least the fulcrum shaft (12) and adjusts the clearance is attached to both sides of the lever body (14a) in the same manner as in the first embodiment. Of course, the collar (14i) may be integrally formed on both sides of the lever body (14a).

  To assemble this part, the base end (14k) of the operating lever (14) is paired with the operating claw (14b) of the operating lever (14) inserted through the through window (13d) of the mounting plate (13). It arrange | positions between these bearing arms (13a), inserts the fulcrum shaft (12), and supports it rotatably. A backlash prevention collar (14i) inserted through the fulcrum shaft (12) is arranged on both sides of the base end (14k). In this state, the lever body (14a) portion and a pair of bearing arms (13a) supporting the lever body (14a) are housed in the handle body (9), and then the pins (17a) (17b) are inserted into the through holes (14h) (14h). Are communicated. In this case, a spacer (14 m) for preventing backlash can be used. The insertion ends of the connected pins (17a) and (17b) are inserted and supported in holding arm holes (18c) and (18d) on the inner surface side of the handle body (9). In this state, the free ends of the pins (17a) and (17b) are inserted into and supported by the holding arm holes (18e) and (18f) of the lid (9e), and are fitted into the notches (9d) to be fixed and fixed. As a result, the actuating lever (14) and the handle body (9) are integrated with each other via the pins (17a) and (17b) so that the handle portion (8) reciprocates around the fulcrum shaft (12). Become.

  In the third embodiment, instead of the pins (17a) and (17b), the lever body (9f) is provided via a plurality of through holes (9f) provided in the recess (9h) of the push operation surface (9a) of the handle body (9). The screw (19) is screwed into the screw hole (14f) of the fixed piece (14e) that is bent at the back of 14a). The recess (9h) is covered with a lid portion (9j) having a fitting-in structure as in the second embodiment.

  As in the second embodiment, the assembly method is performed by attaching the operating lever (14) to the attachment plate (13) and then attaching with the screw (19). The operation itself of the second and third embodiments is exactly the same as that of the first embodiment.
