Example 1

(Basic configuration)

This flat handle (h) is installed on the door (t2) of the body (t1) of the box (t) for the switchboard, and is used as a handle of the door (t2). (Figs. 1(A) and (B))

The flat handle h is inserted into the mounting hole t4 provided on the handle mounting surface t3 of the door t2 and fixed to the door t2. (Fig. 1(B))

In the state in which the door t2 is closed, the flat handle h protrudes the catch (j) from the end of the door (t2), so that the catch (j) is provided in the main body (t1) of the switchgear box (t). ) (Fig. 1(A))

The flat handle (h) includes a case (1) inserted into the mounting hole (t4) and a lever (2) that is raised and received by being folded up to the case (1).

Here, the case 1 corresponds to a “case” provided with a “lever accommodation unit” in the claims (FIG. 1(A),(B)).

The end side of the lever 2 is folded and enters the lever accommodating portion 13 of the case 1 in a folded-up state, and in the expanded state, the case 1 projects from the case 1 to the front of the door t2. The lever 2 can be rotated in a state that occurred in the case 1, that is, in the protruding state. At this time, the latch (j) operates by rotation of the lever (2). When the latch j is separated from the clamp holder t6 by the rotation operation of the lever 2, the door t2 can be opened.

The lever 2 is provided with a lock knob 3 and a latch 44 that are rotatably installed. (Fig. 3(A), (E))

The lock knob 3 is installed to protrude forward from the front of the lever 2 and can hold and turn the lock knob 3 with a thumb and index finger or other finger.

The latch 44 is protruded while the lever 2 is up and stored in the lever receiving portion 13, and the latch 44 is latched by holding the lock knob 3 while being latched by the latch catching portion 17. If it is removed from the locking portion, the lever 2 can be raised to protrude.

In addition, although the existing cylinder lock opened and closed by key operation in Example 1 is shown, it is not excluded that the lock knob 3 is provided with a lock opened and closed by key operation. However, if it is dedicated to places where security is not required, it is advantageous in terms of manufacturing cost to not have a lock such as a cylinder lock, as shown in the example shown.

Hereinafter, the configuration of each part will be described in detail.

(case)

The case 1 is provided with a case body 10, a fixing member 11, and a packing 12. (Fig. 1(B))

The fixing member 11 and the packing 12 are each formed separately from the case body 10.

The case body 10 is formed with a lever receiving portion 13 and a flange 14 (Fig. 1 (B) and Fig. 2 (B)).

The lever accommodating portion 13 is a concave shape that retracts from the front of the case body 10 back, and accommodates the lever 2. The rear side of the lever accommodating portion 13 is a raised portion raised to the rear of the case body 10.

The lever accommodating portion 13 is formed to extend up and down to store the lever 2 vertically so that the end is directed downward.

Further, although not shown, the lever receiving portion 13 may be formed to extend from side to side to accommodate the lever 2 sideways.

The end (bottom) side of the lever 2 is exposed at the opening portion 13e of the lever receiving portion 13 opened to the front side of the case body 10 (Fig. 2(B)).

The lever accommodating portion 13 is a second retracting portion in which the body of the lever 2 continuously formed in the first retracting portion 13a and the first retracting portion 13a accommodating the front end side of the lever 2 is accommodated ( 13b) (FIGS. 2(B) and 3(A), (E)).

The interior of the first retracted portion 13a is retracted further backward than the interior of the second retracted portion 13b. The first retracted portion 13a accommodates the rotating body case 4 installed in the lever 2 when the lever 2 is closed. The latch engaging portion 17 is provided on the inner side of the first retracted portion 13a. (Fig. 3(A))

The latch engaging portion 17 is a recess provided on the side of the inner side of the first retracting portion 13a here. However, if the latch 44 of the locking knob 3 is caught, the latch engaging portion 17 can also be formed as a protruding portion protruding from the side surface.

In the second retracted portion 13b, a through portion 13c is formed on the opposite side to the first retracted portion 13a, that is, here, on the edge side of the second retracted portion 13b (Fig. 1(C) and Fig. 2(B))

The through portion 13c is formed to penetrate the case body 10 back and forth. (not shown)

The flange 14 is a flange that is installed around the opening portion 13e ((FIG. 1(C) and FIG. 2(B)) of the lever receiving portion 13 and contacts the installation surface t3 of the door t2. (Figs. 1(A) to (D) and Fig. 2(B))

As the rear of the case body 10, the rear of the lever receiving portion 13 is inserted into the installation hole t4 of the door t2. (Fig. 1(B))

The packing 12 is arranged to surround the back of the lever receiving portion 13 at the back of the flange 14 of the case body 10. The packing 12 is mounted on the rear surface of the flange 14 before installing the case 1 in the installation hole t4 of the door t2.

As the packing 12, rubber, urethane, plastic, or other materials having elasticity and waterproofness may be employed. By arranging the packing 12 on the rear surface of the flange 11, it is possible to improve the sealing property between the flange 14 and the installation surface t3 of the door t2.

In the state in which the lever receiving portion 13 is inserted into the mounting hole t4, the fixing member 11 is fixed with a fixing screw 16 disposed on the rear side of the lever receiving portion 13 (Fig. 1(B) ))

The flange 14 and the fixing member 11 are fixed while facing back and forth on the installation surface t3 of the door t2 to fix the flat handle h to the door t2.

The fixing screw 16 may employ well-known fixing means such as a screw, a bolt, or a pin.

Specifically, the fixing member 11 is provided between the two pressing portions 11a and the two pressing portions 11a, which are arranged horizontally and extend horizontally to connect the connecting portions 11b connecting the two pressing portions 11a. (Fig. 1(B) to (D))

The connecting portion 11b is provided with a fixing screw insertion portion through which the fixing screw 16 passes. (not shown)

The fixing screw insertion portion may be formed of a hole or a notch portion penetrating the connection portion 11b back and forth.

The connecting portion 11b is fixed to the rear side of the lever receiving portion 13 by the fixing screw 16 above.

The both pressing portions 11a fixed in this way are located on the rear side of the flange 14, with the portion installed on the installation surface t3 of the door t2 interposed therebetween (Fig. 1(B)).

(lever)

The lever 2 is installed in the case 1 and is used as a handle when opening or closing the door t2. (Figs. 1(A), (B) and 2(A), (B))

The lever 2 can be folded to the case 1 in an up-closed state or mounted on the case 1 so as to be protruded so as to be rotated left and right around the upper side in the protruding state, that is, the state that occurred in the case 1. There is. The latch j can be rotated by rotation of the lever 2.

The lever 2 is formed with a hinge part (not shown), an opening 21 and a rotating body case 4 (Fig. 3(A)).

The hinge portion is installed on the bottom rear of the lever 2. The lever 2 can be folded up or down from the case 1 to the case 1 around the hinge portion, and can be projected. The hinge portion includes a hinge shaft and a hinge pin formed separately from the lever 2 (not shown).

The hinge axis above is circular and has a pair of protrusions through which the hinge pin can penetrate the surface (surface).

An end portion of the lever 2 is disposed between the two protruding portions so that the hinge shaft is connected to the end portion of the lever 2 by passing the hinge pin to the rear end portion of the protruding portion and the lever 2.

The hinge pin may be a known pin (not shown). The hinge shaft above is accommodated in the through portion 13c of the lever receiving portion 13 (Fig. 1(C) and Fig. 2(B)).

The center of the hinge axis coincides with the center of the through portion 13c. The center of the hinge shaft and the through portion 13c extends in the front-rear direction of the flat handle h.

A hinge shaft extending back and forth is inserted into the through portion 13c, and a front end side of the hinge shaft is penetrated through the center of the through portion 13c. The catch (j) is fixed to the end side of the hinge shaft. Here, the shaft bolt (g) is a hinge shaft.

By protruding the lever 2 and rotating the front end side of the lever 3 to the left and right, the hinge shaft of the penetrating portion 13c rotates together to rotate the clamp j.

The rotating body case 4 is installed on the rear side of the lever 2. The rotating body case 4 is a case that accommodates the rotating body 30 to be described later. The lever 2 is provided with an opening 21 that opens toward the front side of the lever 2 on the side of the rotating body 4. The rotating case 4 and the opening 21 are formed at the front end side of the lever 2 rather than the hinge portion (FIGS. 1(A), 2(A), (B) and 3(A)). ,(B),(E),(F))

The rotating body case 4 is a concave portion formed integrally with the lever 2 and entering the rear of the lever 2 here. At this time, the rotating body case 4 may be configured separately from the lever 2, and may be formed by being integrally fixed to the lever by means of screws, bolts, pins, or fixing means such as welding or adhesive.

In addition, without using the fixing means to form an engaging portion integral with the lever 2 on the lever 2 side, and by providing an engaging portion integrally with the rotating body case 4 on the rotating body case 4 side These can be implemented to be integrally combined.

The engaging portion has a configuration that cannot be released after the engaging portion is fitted.

For example, as a male member having a ring with elasticity for one of the parts integrally coupled with the engaging portion, the male member can be formed at the same time as it accommodates the male member for the other.

The inner diameter of the opening 21 of the rotating body case 4 and the lever 2 is slightly larger than the outer diameter of the rotating body 30. The opening 21 serves as a display portion that exposes the lock knob 3 and simultaneously displays the indicator 38 to be described later. On the inner circumferential surface of the rotating case 4, a groove-shaped portion (hereinafter, the groove portion 41) is provided along the circumferential direction. (Fig. 3(A), (E))

The rotating body 30 is formed in a cylindrical shape (Fig. 3 (A), (E))

The rotation body 30 is provided with a fall prevention member 37. In this example, the rotating body 30 is provided with a receiving chamber accommodating an elastic member (not shown) such as a fall preventing member 37 and a spring therein, and a part of the falling preventing member 37 is rotated 30 It has a through-hole 35 to protrude to the outside. The anti-missing member 37 is always pressurized with the elastic member so that a part of the anti-missing member 37 protrudes through the through-hole 35 to the outer circumferential surface of the rotating body 30.

When manufacturing the handle, the rotating body 30 is first inserted into the rotating body case 4 from the opening 21.

The anti-missing member 37 contacts the inner circumferential surface of the rotating body case 4 to counteract the pressing of the elastic member and is inserted into the rotating body 30 from the through hole 35.

The fall prevention member 37 is in contact with the inner circumferential surface of the rotating body case 4 and is forcibly inserted into the through hole 35 against pressure of the elastic member. In addition, when the rotating body 30 is pushed into the rotating body case 4 so that the through-hole 35 reaches the groove portion 41 formed on the inner peripheral surface of the rotating body 30, the fall-prevention member 37 passes through the It becomes possible to protrude from the sphere 35, and a part of the fall prevention member 37 is inserted into the groove portion 41.

When the rotating body 30 attempts to retreat toward the opening 21 in the rotating body case 4, the fall prevention member 37 is caught in the groove portion 41 to prevent the retracting of the rotating body 30.

In the above example, the fall prevention member 37 receives the elastic force of the elastic member and protrudes through the through hole 35 as above. In addition, the fall-prevention member 37 may be prepared as an elastic body so that a separate elastic member is not provided.

When a part of the fall prevention member 37 is inserted into the groove portion 41 by using the elastic force of the fall prevention member 37, it is performed without providing the accommodating chamber and the through hole inside the rotating body 30. .

If the accommodation chamber and the through-hole are not installed in the rotating body 30, a spring member such as a C-shaped washer that can extend the fall-prevention member 37 in the inner and outer diameter directions is provided on the outer circumferential surface of the rotating body 30 ( It may also be implemented by providing a recessed groove extending along the circumferential direction (radial direction) of 30) and fitting the anti-falling member 37 into the corresponding groove. (not shown)

In addition, the rotating body case 4 is provided with an opening 42 for opening and closing the latch 44 (Fig. 3(A), (E)).

The opening 42 can penetrate the rotating body case 4 and fold the latch 44 upward in the lever receiving portion 13 installed on the upper side of the rotating body 4 with the lever 2 folded. have.

(Lock knob)

The lock knob 3 is installed on the front surface of the rotating body 30 accommodated in the rotating body case 4, that is, the front surface 31 of the rotating body 30. (Fig. 3(A) and Fig. 4(B)) )

When viewed from the front of the lever 2, the lock knob 3 has one direction in the longitudinal direction and a width w1 (length) in the longitudinal direction is larger than the width w2 in the vertical direction (width direction) orthogonal to the longitudinal direction. (Fig. 3(B))

In the state shown in FIGS. 3(A), (B), (E), and (F), the longitudinal direction of the lock knob 3 is the vertical direction. The locking knob 3 can be rotated on the lever 2 by holding and turning the orthogonal width portion of the locking knob 3 with the thumb and forefinger.

The lock knob 3 is suitable for grabbing and turning with a finger as described above, and has a width w3 exposed to the front of the lever 2 in a folded up state. (Fig. 1(B))

The exposure width w3 is preferably at least 3 mm, and particularly preferably 4 mm to 15 mm. However, if it is possible to hold it with a finger, it is possible that the locking knob 3 has a dimension outside the above numerical range.

Here (Fig. 3(B)), the orthogonal width portion, that is, the thickness between the left and right side surfaces 3a of the lock knob 3 is almost the same over the entire length direction.

However, the thickness between the left and right side surfaces 3a of the locking knob 3 need not be the same throughout the longitudinal direction, and may be partially different.

The locking knob 3 may be such that both sides 3a of the locking knob 3 draw a concave curve such that the middle portion of the longitudinal direction is narrower than both ends of the longitudinal direction when viewed from the front, and vice versa. (3) The locking knob 3 may have a convex curve drawn on both sides 3a so that the middle portion of the longitudinal direction is wider than both ends of the longitudinal direction when viewed from the front. (not shown)

In addition, when viewed from the front, the locking knob 3 may be bent in an even shape or may be inflated in a convex shape.

In addition, in the case of drawing the curve, in any case, the curve may be set only on the left and right sides 3a of the lock knob 3. It is good to leave it installed.

The rear end face 32 of the rotating body 30 includes a projection 36 at a position deviating from the rotation center x of the rotating body 30. (Fig. 3(A), (C), (D), (E), (G), (H) and Fig. 4(B)-(D), (G)-(I))

The latch 44 is a small piece formed separately from the rotating body 30, and has a long hole penetrating inside and outside as a guide portion 44a (Fig. 3(A),(C),(D),(E) ),(G),(H))

In the inside of the rotating body 4, the projection 36 of the rotating body 30 is disposed in the guide portion 44a.

When the rotating body 30 is rotated by holding the locking knob 3 fixed to the rotating body 30 and rotating, the projection 36 rotates around the central axis x of the rotating body 30.

Due to the rotation of the rotating body 30, the projection 36 changes the position of the guide portion 44a while pressing the guide portion 44a.

And in the state in which the lever 2 is raised and folded, the front end side of the latch 44 protruding from the opening 41 intrudes into the latching part 17 and blocks the lever 2 from opening in the case 1. .(Figure 3(A)~(D))

In addition, the latch engaging portion 17 is provided on the upper surface side of the inner surface of the first retracting portion 13a and the opening 42 is installed on the side surface on the rotating body case 4 so that the latch 44 rotates. It may also be made to appear (protrude) from the case 4 upward (not shown).

In the state in which the end of the latch 44 is inserted into the latch engaging portion 17, the locking knob 3 is held and rotated or reversed to circulate the projection 36 so that the latch 44 can be immersed in its original position.

In this example, as shown in Figs. 3(E) to (H), the locking knob 3 is rotated 180 degrees or reversed 180 degrees in the protruding state of the latch 44 shown in Figs. 3A to 3D. Similarly, the latch 44 can be made to appear in the opening 42.

However, by changing the direction of the lock knob 3 to a range other than the above 180 degrees, the latch 44 may be raised and closed.

Further, in this example, the tip of the lever 2 is stored under the case 1 in a folded-up state. Accordingly, the lever 2 can be protruded by placing a finger on the tip of the lever 2 and dragging it while the latch 44 is immersed.

However, a case (1) is provided with a spring member such as a spring (not shown), and when the latch 44 is immersed in the direction in which the lever 2 is always projected, the lever 2 is automatically raised to protrude. can do.

Further, in this example, the indicator 38 indicating the appearance of the latch 44 is mounted on the rotating body 30 (FIGS. 3(A), (E) and 4(E)-(I). ) The indicator 38 is a C-shaped ring, and the outer periphery of the C-shaped constitutes a rotation preventing part 38a with a notch. (Fig. 4(F))

On the inner circumferential surface of the rotating body case (4), a protrusion (not shown) in which the corresponding rotation preventing portion (38a) is tightly fitted is provided, and even if the rotating body (30) rotates by the operation of the locking knob (3), the indicator ( 38) does not change the direction.

The surface (front side) of the indicator 38 includes two classified regions (Fig. 4(E)).

On the outer circumferential surface of the rotating body 30, grooves 33 are formed along the circumferential direction (radial direction) of the rotating body 30 (Fig. 4(B), (D), (G), (I) ) The indicator 38 is fitted into the corresponding groove 33. (Fig. 4(F)-(I))

Cylindrical rotator 30 generally shows an arc when viewed from the front, but a portion of the arc has an incision 34 (FIGS. 3(B),(F) and 4(A),(B),( F),(G))

Here, the cut-out portion 34 shows a straight line on the circular arc when viewed from the front. That is, the groove portion 34 represents a string on the front (front side) arc of the rotating body 3.

In the side view of the rotating body 30, the incision part 34 is provided over the groove 33 in the front face 31 of the rotating body 30, and the incision part 34 and the lever are disposed on the front face of the rotating body 30. A gap is formed between the openings 21 in (2). The gap is used as an indicator, and a part of the surface of the indicator 38 is exposed to the outside through the gap (FIG. 3(B), (F)).

If the gap of the groove portion 34 is to be caused, it can be carried out by having an outline other than the above straight line such as a curve.

By rotating the rotating body 30 by holding and turning the lock knob 3, the direction of the groove portion 34 can be changed to change the color-coded area displayed in the gap on the surface of the indicator 38.

FIG. 4(E) is a region in which a dark color (black) for one side surface of the C-shaped indicator 38 is drawn, and a spot (gray) is displayed on the surface of the indicator 38 other than the region where the dark color is applied. ).

In this example, while the latch 44 is protruding, the incision 34 is directed upward, and the dark colored region of the surface of the indicator 38 can be observed in the gap (FIG. 3(B)). On the other hand, in the state in which the latch 44 is recessed, the incision part 34 faces downward, so that the spot area of the indicator surface can be observed in the gap (FIG. 3(F)).

In the indicator 38, the dark colored region may be a red colored region and the upper spot region may be a green colored region.

The color may not be limited to red and green, but may be performed using a combination of different colors or a combination of areas with different shapes.

As described above, the user can clearly identify and recognize the appearance of the latch 44 by using the supplementary colors, that is, red and green.

When manufacturing the handle, the handle lever 2 can be usefully used in place of the cylinder lock with the rotating case 4. The receiving part (lock case) of the cylinder lock is used as the rotating body case (4).

For example, the lock case (lock receiving case) of the handle cylinder lock shown in Japanese Patent No. 5964218 (Patent Document 2) can be used as the rotating body case 44.

It is also possible to newly design and implement the lever 2, but the manufacturing cost can be reduced by using the lever of the handle with the existing lock as the lever 2 of the present invention as described above.

Example 2

In the first embodiment, the locking knob 3 is installed on the lever 2 side, so that the latch 44 that emerges from the lever 2 folds the lever 2 into the case 1 (case body 10) and is up. It is assumed that it is kept in a stowed state.

At this time, by installing the other locking knob 3 on the case 1 (case body 10) side, the latch 44 that emerges from the case 1 folded the lever 2 into the case 1 to receive the state It shall be maintained.

In addition, by installing the lock knob 3 on the side of the case (1), and rotating the lock knob 3, the lock knob 3 is directly hooked to the lever 2, and the lever 2 is folded to maintain the stored state. It is assumed.

Next, an example in which the lock knob 3 directly applies the lever 2 as the second embodiment will be described.

In Example 2, through holes 22 are provided through the lever 2 back and forth (Figs. 5(A), (C), 6(B) and 7(A), (B)).

The lock knob 3 is rotatably installed in the lever receiving portion 13 of the case 1 (Fig. 6(A), (B)).

The through hole 22 has a length. That is, it is assumed that the through hole 22 has a direction in which the hole width w10 in the longitudinal direction is greater than the hole width w20 in the orthogonal direction in a direction perpendicular to the longitudinal direction in one direction in the longitudinal direction. )

The hole width w10 is slightly larger than the width w1 in the longitudinal direction of the lock knob 3 (FIG. 5(C) and FIG. 7(A)). The hole width w20 is slightly larger than the width w2 in the orthogonal direction of the lock knob 3 , Smaller than the vertical width w1 of the locking knob 3. That is, by aligning the longitudinal direction of the locking knob 3 with the longitudinal direction of the through-hole 22, when the lever 2 is folded up or unfolded, the locking knob 3 can pass through the through-hole 22. (Fig. 5(B), (C) Fig. 6(A), (B) and Fig. 7(B))

With the lever 3 folded, hold the locking knob 3 exposed to the front of the lever 2 through the through-hole 22 and turn it to turn the locking knob 3 in the longitudinal direction to the longitudinal direction of the through-hole 22. By intersecting, the locking knob 3 engages the lever 2 to prevent the protrusion of the lever 2 (FIGS. 5(A) and 7(A)).

In the illustrated example, the through-hole 22 has a longitudinal direction in the vertical direction, but it may also be implemented in the longitudinal direction other than the left and right sides and other vertical directions.

Further, instead of the through hole 22 of the lever 2, the incision portions may be provided on the left and right sides of the lever 2, so that the lock knob 3 and the lever 2 protrude to the front through the incision.

Further, instead of the through-hole 22 of the lever 2, cut portions may be provided on the left and right sides of the lever 2, so that the lock knob 3 is exposed to the front of the lever 2 through the cut portion. Do not).

Here, the lock knob 3 is rotatably installed on the shaft member 6 installed on the front surface (surface) of the substrate 5 (Fig. 6(A), (B) and Fig. 7(A) ~ (E))

The substrate 5 exemplifies a rectangular plate-shaped piece, but may be implemented by employing a circular shape or other shapes.

Screw fastening holes 51 are formed at the two opposite edges of the substrate 5 from the front to penetrate the substrate 5 back and forth (front to back). The substrate 5 is provided with a shaft member installation hole 52 between two screw fastening holes 51. A female screw is formed in the screw fastening hole 51. Further, the screw fastening holes 51 may be provided at the corners of the substrate 5, or may be disposed above and below the shaft member mounting holes 52 with the shaft member mounting holes 52 interposed therebetween.

A male screw is formed on the rear end 61 of the shaft member 6, and a head 62 is formed on the front end side of the shaft member 6 (Fig. 7(C)).

The head 62 of the shaft member 6 has a seating surface.

In the intermediate position in the longitudinal direction of the locking knob 3, an insertion hole 39 is provided to penetrate the locking knob 3 back and forth.

After passing the insertion hole 39 of the lock knob 3 together with the tubular space 7 in the shaft member 6, the rear end of the shaft member 6 is inserted into the shaft member installation hole 52, and the shaft member ( 6) can be fixed (stand up) to the substrate 5.

The head 62 of the shaft member 6 comes into contact with the seating surface so that the locking knob 3 does not come off the shaft member 6.

By attaching the screws 53 to the screw fastening holes 51 of the substrate 5 on which the lock knob 3 is mounted, the screws 53 are attached to the substrate formed in the lever receiving portion 13 of the case 1 Fastened to the portion 13d, the substrate 5 can be fixed to the case 1.

Here, the screw 53 is coupled to the screw fastening hole 51 of the board 5 on which the lock knob 3 is mounted, and the screw is attached to the board attaching part 13d installed in the lever receiving part 13 of the case 1. By fastening 53), the board 5 can be fixed to the case 1 (Fig. 6(A),(B)).

The substrate mounting portion 13d is a surface for mounting the substrate 5 provided at the bottom of the lever receiving portion 13 of the case 1. Above and below the substrate mounting portion 13d, a protruding portion 13f that is raised from the bottom of the lever receiving portion 13 is formed.

The protruding portion 13f is provided for positioning the substrate 5 when the substrate 5 is fixed to the substrate attachment portion 13d with screws 53.

The locking knob 3 is supposed to have an insertion hole 39 in the center of the longitudinal direction, but may also be provided with the insertion hole 39 in a position biased to one side in the longitudinal direction (FIG. 7(F)), It can also be carried out so that only the left and right sides of the front through-hole 22 of the lever 2 are caught.

Is installed, the lock housing case 7 is stored with the cylinder lock 70, the latch piece 72 that appears in the lock housing case (7) (Fig. 6 (A))

Moreover, the lock housing case 7 accommodates a spring that holds the latch piece 72 in a direction protruding from the lock housing case 7 (not shown).

A latch piece engaging portion 81 is provided on the lever receiving portion 13 of the case 1 (Fig. 6(B)).

The lever piece 2 is folded up, and the latch piece 72 (Fig. 6(A)) is configured to engage the latch piece engaging portion 81 (not shown).

The latch piece engaging portion 81 is fixed to the shaft so as to be rotatable in the case 1 (Fig. 6(B)).

A push button 8 is installed on the front side of the lever 2. The case 1 is provided with an operating member (not shown) that pushes the latch piece 72 again in conjunction with the operation of the push button 8.

When the push button 8 is pressed while the longitudinal direction of the lock knob 3 coincides with the longitudinal direction of the through hole 22 of the lever 2, the latch piece 72 is retracted in the direction sinking by the operating member. And it is separated from the latch piece engaging portion 81.

In the above, the latch piece 72 can be separated from the latch piece engaging portion 81 to protrude the lever 2.

In this example, the case 1 is provided with a carbon member, such as a spring, which holds the lever 2 in an always standing direction (not shown), and the latch piece 72 has the latch piece engaging portion 81 as described above. By being released from, the lever 2 automatically unfolds and protrudes.

The cylinder lock 70 can be locked or opened by inserting and operating a key (not shown) in the key hole 71. In the locked state of the cylinder lock 70, the latch piece 72 maintains a state protruding from the lock receiving case 7. Therefore, even if the push button 8 is pressed in the locked state, it is impossible to push the latch piece 72 back by the operating member.

In the second embodiment, by looking at the direction of the lock knob 3, it can be determined whether the lever 2 is folded or protruded. That is, in the second embodiment, the locking knob 3 itself also serves as the indicator 38 in the first embodiment.

In Example 2, the case shown in Japanese Patent No. 3131336 (Patent Document 3) can be used as the case (1). The case shown in Patent No. 3131336 (Patent Document 3) can be provided with a ring member capable of passing a hook of a lock, and the substrate 5 having a lock knob 3 mounted on the case in place of the ring member It is good to install. However, since the through-hole of the handle lever shown in Patent No. 3131336 is circular when viewed from the front, the locking knob 3 cannot be fastened. Therefore, it is necessary to adopt a type having a length as a through hole through which the ring member passes through the lever of the second embodiment. The construction of the lock knob 3 on the case 1 and the lever 2 is not excluded, but the manufacturing cost can be suppressed by using the components of the existing handle, such as Patent No. 331636. have. In addition, the hook member may be formed to pass through a hook of another lock, for example, a hook of a dial lock, and a through hole may be of a length to use a lever provided with such an annular member in the practice (production) of the present invention. It is necessary to adopt the type to have.

The case 1 and the lever 2 are not excluded from designing and implementing a new configuration of the lock knob 3, but the manufacturing cost can be reduced by using a component member of an existing handle such as Patent No. 331636 Can.

In addition, in Example 2, the matter not specifically mentioned is also the same in Example 1.

In addition, in the example shown in FIGS. 5 to 7, a cylinder lock is provided as a handle locking member, and in another embodiment 2, the handle may be provided without the lock.

In addition, in the second embodiment, a through hole 22 is provided in the lever 2 and the lock knob 3 on the case 1 side is passed through the through hole 22 of the lever 2 to lock the lever 2. The knob 3 is to be hooked, and the other is to install the locking knob 3 in the vicinity of the front opening 13e of the case 1, without providing a through hole in the lever 2 can do.

In Example 2, an example of a change of the structure in which the lock knob 3 is installed in the case 1 of FIGS. 8A and 8B is shown.

In this example, the positioning of the substrate attaching portion 13d protruding forward from the deep bottom of the lever receiving portion 13 without providing the protruding portion 13f shown in Figs. 7(A) and (B) in the case 1 It constitutes a portion (13g). The board|substrate 5 is fitted in the positioning part 13g of the said board|substrate mounting part 13a, and the concave part for determining the position of the board|substrate 5 is comprised in the mounting part 54 on the back side. (FIG. 8B) ).

The upper portion of the hill-shaped portion 55 is provided with a hole 56 that penetrates the hill-shaped portion 55 back and forth, and the hole 56 is an inner space of the hollow hill-shaped portion 55 and a hill-shaped portion 55 ) Communicate with the outside.

Here, the locking knob 3 is provided with the insertion hole 39 (FIG. 7(C)), and the shaft portion is integrally formed with the locking knob 3 instead of the separate shaft member 6 as well. The shaft portion is composed of a small diameter portion (6a) and a large diameter portion (6b).

The small-diameter portion 6a protrudes behind the lock knob 3 formed on the rear surface of the lock knob 3. Behind the small-diameter portion 6a, a large-diameter portion 6b that is continuous with the small-diameter portion 6a is formed. In the shaft portion, the diameter of the large-diameter portion 6b is larger than the inner diameter of the hole 56, and the diameter of the small-diameter portion 6a is smaller than the inner diameter of the hole 56.

When the small-diameter portion 6a is accommodated in the interior space of the hill-shaped portion 55, the lock-knob 3 can be installed on the substrate 5 by passing the small-diameter portion 6a through the hole 56.

In this example, the substrate 5 is formed by dividing the lower half 5a and the upper half 5b, and when mounted on the case 1 of the substrate 5, the lower half 5a and the upper half 5b are separated, The large neck portion 6b may be accommodated in the inner space of the divided hill-shaped portion 55. The lower half portion 5a and the upper half portion 5b of the substrate 5 are fixed to the substrate attachment portion 13d by screws 53, respectively, and are integrated.

In addition, in the example shown in FIG. 8, the engaging portion 82 of the push button 8 is provided at the top of the push button 8, and the engaging portion of the push button 8 is provided at the end (bottom) of the lever 2.
