BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described based on the drawings. For convenience of explanation, U is upward, S is downward, F is forward, and B is backward in each figure.

(First embodiment)
(basic configuration)
This flat handle h is attached to a door t2 that closes the main body t1 of the switchboard box t, and is used as a handle for the door t2 (FIGS. 1(A) and 1(B)).
The flat handle h is inserted into a mounting hole t4 provided in the handle mounting surface t3 of the door t2 and fixed to the door t2 (FIG. 1(B)). When the door t2 is closed, the flat handle h causes the latch j to protrude from the tip of the door t2, and engages the latch j with the latch receiving portion t6 provided on the main body t1 of the switchboard box t (Fig. 1 (A )).

The flat handle h includes a casing 1 inserted into the mounting hole t4 and a lever 2 that rises and falls with respect to the casing 1. As shown in FIG. In this example, the casing 1 corresponds to the "substrate" provided with the "lever receiving portion" in the claims (FIGS. 1(A) and (B)).
The tip side of the lever 2 is housed in the casing 1 (lever receiving portion 13) when it is laid down, and protrudes from the casing 1 forwardly of the door t2 when it is set up.
The lever 2 can be rotated with respect to the casing 1 (door t2) in the state opened from the casing 1, that is, in the standing state. The latch j rotates as the lever 2 rotates. By rotating the lever 2, the latch j can be released from the latch receiving portion t6 and the door t2 can be opened.

The lever 2 includes a rotatably provided knob 3 and a latch 44 (FIGS. 3(A) and 3(E)). A knob 3 protrudes forward from the front surface of the lever 2 and can be pinched with the thumb and other fingers such as the forefinger. The knob 3 can be rotated with respect to the lever 2 by pinching and twisting the knob 3 .

In the first embodiment, an example is shown in which a lock such as a cylinder lock for locking/unlocking by key operation is not provided, but locking/unlocking is performed by key operation together with the knob 3. It does not exclude those with locks. However, if it is to be used exclusively for places where security is not required, as shown in the example shown in the figure, it is more advantageous in terms of manufacturing cost to use a device that does not have a lock such as a cylinder lock.
The configuration of each unit will be described in detail below.

(Casing 1)
The casing 1 includes a casing body 10, a fixing member 11, and a packing 12 (FIG. 1(B)).
The fixing member 11 and the packing 12 are formed separately from the casing main body 10, respectively.
A lever receiving portion 13 and a flange 14 are formed in the casing main body 10 (FIGS. 1(B) and 2(B)).

The lever receiving portion 13 is a concave portion which is retracted rearward from the front surface of the casing body 10 and accommodates the lever 2 . The rear side of the lever receiving portion 13 is a raised portion that protrudes rearward from the casing body 10 . The lever receiving portion 13 extends vertically in this example, and the lever 2 is vertically accommodated with its tip facing downward. Although not shown, the lever receiving portion 13 may extend left and right to accommodate the lever 2 laterally.
The tip (lower end) side of the lever 2 appears and disappears from the open portion 13e of the lever receiving portion 13 that opens to the front surface of the casing body 10 (FIG. 2(B)).
The lever receiving portion 13 includes a first retracted portion 13a that accommodates the tip side of the lever 2, and a second retracted portion 13b that is formed continuously with the first retracted portion 13a and accommodates the base side of the lever 2 (FIG. 2(B) and FIGS. 3(A)(E)).
The inside of the first recessed portion 13a is recessed rearward from the inside of the second recessed portion 13b. The first retracted portion 13a accommodates the rotating body case 4 attached to the lever 2 when the lever 2 is closed.

The latching portion 17 is provided on the inner side surface of the first recessed portion 13a (FIG. 3(A)).
In this example, the latching portion 17 is a concave portion provided on the upper side surface of the inner side surface of the first recessed portion 13a. However, if the latch piece 44 of the lock member 3 is hooked, the latch engaging portion 17 can be formed as a convex portion projecting from the upper side surface.
A tubular portion 13c is formed in the second recessed portion 13b on the side opposite to the first recessed portion 13a, that is, in this example, on the upper end side of the second recessed portion 13b (FIGS. 1(C) and 2(B)). )
Inside the tubular portion 13c, a through portion (not shown) that penetrates the casing main body 10 (the rear end surface portion of the tubular portion 13c) in the front-rear direction is provided.

The flange 14 is provided on the periphery of the open portion 13e (FIGS. 1(C) and 2(B)) of the lever receiving portion 13 and is a flange that abuts on the mounting surface t3 of the door t2 (FIG. 1(A)). (D) and FIG. 2(B)).
The rear side of the lever receiving portion 13 protruding from the rear surface of the casing body 10 is inserted into the attachment hole t4 of the door t2 (FIG. 1(B)).
The packing 12 is formed in an annular shape and arranged to surround the back of the lever receiving portion 13 on the back of the casing body 10 (flange 14). The packing 12 is attached to the rear surface (rear surface) of the flange 14 before attaching the casing 1 to the attachment hole t4 of the door t2. The packing 12 may be made of rubber, urethane, plastic, or any other elastic and waterproof material. By disposing the packing 12 on the rear surface of the flange 11, it is possible to improve the airtightness between the flange 14 and the mounting surface t3 of the door t2.

With the lever receiving portion 13 inserted into the mounting hole t4, the fixing member 11 is fixed by a fastener 16 arranged on the rear side of the lever receiving portion 13 (FIG. 1(B)).
The planar handle h is fixed to the door t2 by sandwiching the portion of the door t2 provided with the mounting surface t3 from the front and rear between the flange 14 and the fixing member 11 .
Fasteners 16 may employ well-known fixing means such as screws, bolts or pins.
Specifically, the fixing member 11 includes two pressing portions 11a that extend vertically and are arranged horizontally, and a connecting portion 11b that is provided between the pressing portions 11a and connects the pressing portions 11a (see FIG. 1). 1(B)-(D)).
The coupling portion 11b is provided with a fastener insertion portion (not shown) through which the fastener 16 is passed. The fastener insertion portion can be formed as a hole or a notch that penetrates the connecting portion 11b in the front-rear direction. The connecting portion 11b is fixed to the rear surface of the lever receiving portion 13 by the fastener 16 described above. By this fixation, both pressing portions 11a are positioned behind the flange 14 across the portion of the door t2 where the mounting surface t3 is provided (FIG. 1(B)).

(lever 2)
The lever 2 is provided on the casing 1, which is the base, as a handle for opening and closing the door t2 (FIGS. 1A, 1B and 2A, 2B).
The lever 2 is attached to the casing 1 so as to be able to rise and fall, and can rotate left and right around the base end (upper end) side in a standing state, that is, a state opened from the casing 1 . This rotation of the lever 2 allows the latch j to rotate.
A hinge portion (not shown), an opening 21, and a rotor case 4 are formed in the lever 2 (FIG. 3(A)).

The hinge portion described above is provided on the rear surface of the base portion of the lever 2 . The lever 2 can be raised and lowered with respect to the casing 1 around this hinge portion. The hinge portion includes a base formed separately from the lever 2 and a horizontal shaft extending in the horizontal direction (not shown). The base is a disc, and has a pair of standing portions on its surface (board surface) through which the horizontal shaft can be passed. The rear end of the lever 2 is arranged between the two raised portions, and the horizontal shaft is passed through the raised portion and the rear end of the lever 2, so that the base is axially fixed to the rear end of the lever 2. As shown in FIG. A well-known pin can be used for the horizontal axis (not shown). The base described above is housed in the cylinder portion 13c of the lever receiving portion 13 (FIGS. 1(C) and 2(B)). The central axis of the base, which is a disk, substantially coincides with the central axis of the cylindrical portion 13c. Both the central axis of the base plate and the central axis of the cylindrical portion 13c are imaginary lines extending in the longitudinal direction of the planar handle h.
A shaft extending in the front-rear direction is inserted through the penetrating portion, and the distal end side of the shaft is passed through the center of the base. The latch j is fixed to the proximal end of the shaft. In this example, the axis is the shaft of bolt g.
By raising the lever 2 and rotating the tip side of the lever 3 to the left and right, the base in the cylindrical portion 13c rotates together with the shaft, and the latch j can be rotated.

The rotating body case 4 is provided on the back side of the lever 2 . The rotating body case 4 is a case that accommodates a rotating body 30, which will be described later. The lever 2 also has an opening 21 that opens to the front side of the lever 2 as a mouth of the rotor case 4 . The rotating body case 4 and the opening 21 are formed closer to the tip side of the lever 2 than the hinge portion (FIGS. 1A, 2A, 2B, 3A, 3B, and 3A). E) (F)).
In this example, the rotating body case 4 is a recess formed integrally with the lever 2 and recessed behind the lever 2 . However, the rotor case 4 may be formed separately from the lever 2 and formed by fixing means such as screws, bolts, pins, welding, or adhesive. Instead of using the fixing means, it is possible to form an engaging portion integrally with the lever 2 on the lever 2 side and provide an engaged portion integrally with the rotating body case 4 on the rotating body case 4 side. . The engaging portion is designed to fit the engaged portion, that is, to have a form that does not come off after being engaged. For example, one of the locking portion and the locked portion can be formed as a male member having an elastic hook, and the other can be formed as a female member that accommodates the male member and is hooked by the hook member.

The inner diameters of the rotating body case 4 and its opening 21 are slightly larger than the outer diameter of the rotating body 30 .
The opening 21 exposes the knob 3 and also serves as an indicator display portion for exposing an indicator 38, which will be described later.
The internal space of the rotating body case 4 is substantially circular when the lever 2 is viewed from the front, and in this example, the opening 21 is also substantially circular when viewed from the front.
A groove-shaped portion (hereinafter referred to as a groove portion 41) is provided on the inner peripheral surface of the rotating body case 4 along the circumferential direction of the inner peripheral surface (FIGS. 3A and 3E).
The rotating body 30 described above is formed in a cylindrical shape (FIGS. 3A and 3E). A retaining member 37 is provided on the rotating body 30 . In this example, the rotating body 30 is provided with a housing chamber for housing therein a retaining member 37 and an elastic member (not shown) such as a spring, and a through hole 35 through which a part of the retaining member 37 protrudes to the outside of the rotating body 30 . Prepare. The retaining member 37 is always pressed by the elastic member so that a portion of the retaining member 37 protrudes from the outer peripheral surface of the rotor 30 through the through hole 35 . When the rotating body 37 is first inserted into the rotating body case 4 through the opening 21 during the manufacture of the handle, the retaining member 37 comes into contact with the inner peripheral surface of the rotating body case 4 and pushes against the pressure of the elastic member to push the through hole 35. is pushed back into the rotating body 30 from the Further, when the rotating body 30 is pushed into the rotating body case 4 and the through hole 35 reaches the groove portion 41 provided on the inner peripheral surface of the rotating body 30, the retaining member 37 can protrude from the through hole 35. As a result, part of the retaining member 37 enters the groove 41 . When the rotating body 30 attempts to move backward from the rotating body case 4 toward the opening 21, the retaining member 37 is caught in the groove 41 to prevent the rotating body 30 from moving backward.

In the above example, the retainer member 37 is urged by the elastic member to protrude from the opening as described above. In addition, it is also possible that the retaining member 37 itself has elasticity and that the elastic member is not provided. When part of the retaining member 37 is inserted into the groove 41 by utilizing the elasticity of the retaining member 37, it is also possible to carry out without providing the accommodating chamber or the through hole in the rotating body 30. FIG. If the rotating body 30 is not provided with the accommodation chamber or the through hole, the retaining member 37 is a spring member such as a C-shaped washer that can be expanded and contracted in the radially inner and outer directions. It is also possible to provide a recessed groove extending along the (radial direction) and fit the retaining member 37 into the recessed groove (not shown).

Further, the rotating body case 4 is provided with an opening 42 for allowing the latch 44 to protrude and retract (FIGS. 3(A) and 3(E)). The opening 42 penetrates the rotating body case 4 and is provided on the upper side of the rotating body case 4 when the lever 2 is laid down (down state). be able to.

(Knob 3)
The knob 3 is provided on the front surface of the rotating body 30 housed in the rotating body case 4, that is, on the front end face 31 of the rotating body 30 (FIGS. 3A and 4B).
The knob 3 has a long side. That is, in the front view of the lever 2, one direction of the knob 3 is the longitudinal direction, and the width w1 (length) in the longitudinal direction is larger than the width w2 in the orthogonal direction (width direction) perpendicular to the longitudinal direction. (Fig. 3(B)). In the states shown in FIGS. 3A, 3B, 3E, and 3F, the longitudinal direction of the knob 3 is the vertical direction. The knob 3 can be rotated with respect to the lever 2 by pinching the width portion of the knob 3 in the orthogonal direction with the thumb and index finger or middle finger.
The knob 3 has a protrusion width w3 from the front of the lever 2 in the prone state, which is suitable for pinching and rotating with fingers as described above (FIG. 1(B)). The protrusion width w3 is preferably at least 3 mm or more, particularly preferably 4 mm to 15 mm. However, the knob 3 may have dimensions outside the above numerical range as long as it can be picked up with the fingertips.

In this example (FIG. 3(B)), the width portion in the orthogonal direction, that is, the thickness between the left and right side surfaces 3a of the knob 3 is substantially the same over the entire longitudinal direction. However, the thickness between the left and right side surfaces 3a of the knob 3 does not need to be the same over the entire longitudinal direction, and may be partially different. For example, both side surfaces 3a of the knob 3 may be curved in a concave shape so that the middle portion of the knob 3 in the longitudinal direction is narrower than the width of both longitudinal ends when viewed from the front. Both side surfaces 3a of the knob 3 may be convexly curved (not shown) so that the width of the middle portion of the knob 3 in the longitudinal direction is larger than that of both longitudinal end portions in a front view. That is, when viewed from the front, the knob 3 may be hung like a hand drum or swollen like a barrel.
In any case of drawing the curve, the curve may be provided only on one of the left and right side surfaces 3a of the knob 3. FIG.

A rear end face 32 of the rotating body 30 is provided with a protrusion 36 at a position away from the rotation center x of the rotating body 30 (FIGS. (B)-(D)(G)-(I)).
The latch 44 is a small piece formed separately from the rotating body 30, and has a long hole penetrating from the front and back as a guide portion 44a (FIGS. 3A, 3C, 3D, 3E, 3G, 3H )). In the rotary body case 4, the protrusion 36 of the rotary body 30 is arranged in the guide portion 44a.
When the knob 3 fixed to the rotating body 30 is pinched and rotated to rotate the rotating body 30 , the projections 36 rotate around the central axis x of the rotating body 30 . Due to the rotation of the protrusion 30, the protrusion 36 presses against the guide portion 44a and changes its position within the guide portion 44a. The latch 44 slides in response to the pressure and displacement of the protrusion 36, and appears and disappears from the opening 42 as described above.
When the lever 2 is lying down, the tip end of the latch 44 protruding from the opening 41 enters the latch engaging portion 17 to prevent the lever 2 from opening from the casing 1 (FIGS. 3A to 3D). ).
The latching portion 17 is provided on the upper surface side of the inner surface of the first retreating portion 13a, and the opening 42 is provided on the upper surface side of the rotating body case 30 so that the latch 44 can appear and disappear (protrude upward) from the rotating body case 4. ) (not shown).

With the tip of the latch 44 inserted into the latching portion 17, the knob 3 is pinched and further rotated or reversed to rotate the projection 36 and retract the latch 44 to its original position.
In this example, the latch 44 is opened as shown in FIGS. 3(E)-(H) by rotating the knob 3 180 degrees or reversing it 180 degrees from the protruding state of the latch 44 shown in FIGS. 3(A)-(D). It can be submerged through the opening 42 . However, the latch 44 may appear and disappear by changing the orientation of the knob 3 within a range other than the above 180 degrees.
In this example, the tip of the lever 2 protrudes downward from the casing 1 in the prone state. Therefore, when the latch 44 is retracted, the lever 2 can be erected by putting a finger on the tip of the lever 2 and pushing it up. However, it is assumed that an elastic member (not shown) such as a spring is provided in the casing 1 to always urge the lever 2 in the direction to stand up, and that the lever 2 automatically stands up when the latch 44 is retracted. good too.

Further, in this example, the indicator 38 indicating the protruding/retracting state of the latch 44 is attached to the rotating body 30 (FIGS. 3(A), 3(E) and 4(E) to (I)). The indicator 38 is a C-shaped ring, and a cutout portion is provided as a detent 38a on the outer circumference of the C (FIG. 4(F)). A protruding portion (not shown) fitted to the detent 38a is provided on the inner peripheral surface of the rotator case 4 so that the indicator 38 does not change direction even if the rotator 30 is rotated by the operation of the knob 3.
The indicator 38 has two color-coded areas on the surface (front) (FIG. 4(E)). A groove 33 is formed in the outer peripheral surface of the rotating body 30 along the circumferential direction (radial direction) of the rotating body 30 (FIGS. 4B, 4D, 4G, and 4I). The indicator 38 is fitted (FIGS. 4(F) to (I)).
The cylindrical rotating body 30 has a generally circular arc when viewed from the front, and has a notch 34 in a part of the circular arc (Figs. 3(B)(F) and 4(A)(B)(F). ) (G)). In this example, the notch 34 presents a straight line with respect to the arc when viewed from the front. That is, the notch 34 forms a chord with respect to the circular arc on the front surface (front end surface) of the rotor 3 .
The notch 34 extends from the front end surface 31 of the rotor 30 to the groove 33 when viewed from the side of the rotor 30 . is occurring. The gap is used as an indicator display portion, and a part of the surface of the indicator 38 is exposed to the outside through the gap (FIGS. 3(B) and 3(F)). The notch 34 can have a contour other than the straight line, such as a curve, as long as it creates the gap.

By pinching and turning the knob 3 to rotate the rotating body 30, the direction of the notch 34 can be changed, and the color-coded regions exposed from the gaps on the surface of the indicator 38 can be changed.
In FIG. 4(E), one end side surface of the C-shaped indicator 38 is drawn as a dark colored (black) area, and other portions of the surface of the indicator 38 other than the dark colored area are marked with spots (gray). is depicted as the region marked with .
In this example, when the latch 44 protrudes, the notch 34 faces upward, and the dark-colored area on the surface of the indicator 38 can be seen through the gap (FIG. 3(B)). On the other hand, when the latch 44 is sunk, the notch 34 faces downward and the spotted area of the indicator surface can be seen through the gap (FIG. 3(F)).
In the indicator 38, for example, the dark-colored area may be a red-colored area, and the spotted area may be a green-colored area. The above-described color coding is not limited to red and green, and can be implemented as a combination of other color schemes or a combination of regions with different patterns. As described above, the combination of complementary colors, that is, red and green, which is the complementary color of red, allows the observer to clearly distinguish and recognize the appearing and retracting states of the latch 44 .

When the handle is manufactured, the lever 2 of the handle provided with a cylinder lock can be used as the rotating body case 4 . The accommodating portion (lock case) for the cylinder lock is used as the rotating body case 4 . For example, a lock case (lock storage case) for a handle tumbler lock shown in Japanese Patent No. 5964218 (Patent Document 2) can be used as the rotating body case 44 .
Although it is possible to design and implement the lever 2 anew, as mentioned above, by utilizing the lever of an existing lockable handle as the lever 2 of the present invention, manufacturing costs can be reduced.

(Second embodiment)
