Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a retractable projection handle, which is useful as a door handle, especially for a handle that also locks a thin door body in a steel rocker or a switchboard. It is a thing.

[Conventional technology]

A locking device is attached to a door of the switchboard so that an unspecified person cannot freely open the door, and the door is opened and closed by operating a handle with a knob or lever under unlocking.

By the way, most of this kind of switchboards, lockers, etc. are installed facing the passage, and in such an installed state, the knob or lever protruding from the door body obstructs passage.

In response to this, a fingertip insertion part is formed by denting a part of the door panel, and the latch release lever arranged on the same surface as the panel is pulled up from the back side with the fingertip at the end of the part. The handle mechanism is known.

However, these protruding knobs or levers and the handle mechanism that is pulled up from the back side have a structure that can be easily broken and unlocked by the lever action on these knobs or levers. There is.

Therefore, a handle device including a knob or a lever without a hanging structure such as a lever in the handle lock mechanism is desired.

And, an example of such a handle device is SAIKAI Sho 53-933.
As disclosed in Japanese Patent Laid-Open No. 94, the tip of a handle equipped with a cylinder lock device is fitted into a front recess of a mechanism body attached to a door panel at a closed position, and the handle is first unlocked when the cylinder lock device is unlocked. It is a project handle that is projected from the insertion position of.

In the conventional means disclosed herein, both the handle and the case-side locking connecting member are attached to the mechanism main body so as to be openable, and the movement of the handle and the connecting member at the protruding position of the handle is possible. Cylinder locking device arranged in the central portion of the handle and the connecting member are arranged in a longitudinal axial arrangement so as to form a push-fitting force applied to the handle. Springs are arranged along the outer circumference of the connecting member in a column with the handle.

[Problems to be solved by the device]

By the way, a door such as a switchboard or a steel locker is formed of a single metal panel, and the thickness of the door including the frame material is about 1 cm, which is extremely thin.

Therefore, as for the handle mechanism attached to these thin door bodies, by making the thickness thereof as thin as possible, bulkiness in the housing is prevented, and the structure of the locking body that is locked with the housing side frame is easy. Become.

In this respect, in the above-mentioned conventional means, since the connecting member, the springs, and the like are arranged in a column in relation to the handle that moves in and out, it becomes vertically long by that amount, and there is a concern that it will be applied to the above thin door body.

Therefore, the present invention aims to develop a projection handle which can be applied not only to a normally thick door or the like but also to such a thin door body.

[Means for Solving the Problems]

In order to achieve this object, the projection handle of the present invention first comprises an inner cylinder having a cylinder locking device and an outer cylinder having a gap between the inner cylinder and the housing, which is integral with the fixing flange. It has a quadruple tubular structure in which a handle made of a tube and a joint member having engaging portions at two axial positions are fitted to a latch operated by the locking device.

Then, the handle in which the outer cylinder is slidably fitted into the housing so as to be able to move in and out while being prevented from rotating is provided with a protruding movability direction by a spring arranged and arranged in a gap between the outer cylinder and the inner cylinder. A regulating means for releasing the rotation prevention with respect to the housing in the projecting area is provided.

In addition, the joint member, which allows the handle to move in and out and is arranged integrally along the outer circumference of the inner cylinder in the rotational direction, is rotatably assembled to the housing, and one of the one of the members is rotated. The engaging portion faces the latching position of the latch in the press-fitting area of the handle, and the other engaging portion faces the latching position of the latch in the protruding area of the handle.

Then, a locking member is provided at the interlocking portion of the joint member.

[Action]

According to the above-mentioned means of the present invention consisting of a quadruple cylinder structure, the length of the mechanism basically depends on the protruding length of the handle. More specifically, the protruding length of this handle only adds to the very limited structural thickness required to assemble the components.

And as a device configuration that enables this locking structure,
The structure in which the inner cylinder of the handle is placed along the joint member for mounting the locking member on the housing side, and the cylinder lock device assembled to the inner cylinder is operated (engagement / disengagement of the latch) with the member works effectively. . That is, according to this configuration, the joint member and the handle can be juxtaposed at the fitting position of the handle, and the mechanism itself does not require a space in the vertical position for incorporating the joint member.

Similarly, by locating the spring in the gap between the inner and outer barrels of the handle, there is no need for vertical mounting space therefor.

The handle, which is press-fitted into the housing against the expansion force of the spring, is a lateral projection of the latch in the cylinder lock device, which is held by being engaged with one locking portion of the joint member.

When the latch is pulled from its engagement position by a key operation on the lock device, the handle released from the engagement state is projected from the housing by the expansion force of the spring.

The handle, which has been released from the rotation-preventing action on the housing at this protruding position, grips this handle and performs a rotation operation, thereby rotating the joint member integrally coupled therewith in the rotation direction.

By this rotation, the locking member provided in the interlocking portion of the member is moved from the previously locked position on the housing side to the unlocked position.

The action of preventing the rotation of the housing with respect to the handle in the region where the handle is press-fitted into the housing is to prevent the key from operating in the cylinder lock device (operation in the rotation direction).
It serves to hold the handle or locking device in a rest position.

(Example) Next, the illustrated example of this invention is described.

The cylindrical housing 1 has a flange 2 on the outer peripheral end thereof, and a door panel is sandwiched and fixed between the flange 2 and a nut 3 screwed to the peripheral thread.

The handle 4 is composed of a small-diameter inner cylinder 4a and a large-diameter outer cylinder 4b.
A well-known cylinder lock 5 is incorporated in the inner cylinder 4a, and a vertically long ridge 6 (see FIG. 2) provided on a part of the outer circumference of the outer cylinder 4b is slidably fitted in a vertically long groove 7 formed in the inner wall of the housing 1. Then, the housing 1 is fitted into the housing 1 so as to be able to move in and out while being prevented from rotating, and a cutting portion 6a is provided in the inner end region of the vertically elongated ridge 6, and the cutting is performed by the protrusion of the handle 4. When the portion 6a reaches the outer end region of the longitudinal groove 7, a regulation means is provided so that the rotation preventing action up to that time is released and the structure can be rotated.

Further, the handle 4 has the knob portion 4c at the outer end thereof fitted into the internal recess 8 of the flange 2 in the fitted position,
The outer end surface of the handle 4 and the outer end surface of the housing 1 are substantially the same.

Reference numeral 9 denotes a joint member, in which a cylindrical groove is partially removed to form a vertical groove 10, and engaging portions 12 and 13 are formed by a long groove 11a and a groove 11b in which the opposing peripheral wall is partially removed. is there. Then, the joint member 9 is slidably fitted to the inner cylinder 4a of the handle 4 with the jetty 14 formed on the outer periphery thereof and the vertical groove 10 so as to be integrally slidable in the axial direction in the rotational direction. In addition, with its inner end in contact with the inside of the bottom inner flange 1b of the housing 1, the sliding contact plate 15 and the screw 16 (see FIG. 3, FIG. (See FIG. 6) and is rotatably attached to the housing 1.

Reference numeral 17 is a latch in the cylinder lock device, which is biased by a latch spring 20 so that the semi-circular cam shaft of the cylinder lock 5 is pressed.
18 (see FIG. 3) is slidably fitted and retained by a retainer 19 so that the handle cylinder 4a is assembled and fitted into the joint member 9 and brought into contact with the locking portion 12 of the joint member 9. is there.

21 is a handle spring, which is the inner cylinder 4a and the outer cylinder.
Both ends are disposed in a gap between the inner wall of the handle 4 and the inner flange 1b of the bottom of the housing 1 with a protect washer 22 interposed therebetween in a gap between the inner wall 4b and the inner wall 4b.

On the other hand, a mounting shaft 24 having a receiving collar 23 is provided on the outside of the rotatable sliding contact plate 15, and one end of a locking member 25 is fitted to the shaft 24 and fixed under the interposition of a flat washer 26. It is secured by a bolt 27.

According to the embodiment having such a structure, as shown in FIG. 5, in the mechanism in which the peripheral edge of the mounting portion of the door panel is sandwiched and fixed between the flange 2 and the nut 3, the handle 4 is fitted into the housing 1. At the position shown by the solid line in FIGS. 5 and 1, the locking member 25 attached to the rear end is at the position shown in FIG. 6 and engages with the receiving member (not shown) on the housing side to lock the door. Is in a state.

From this state, when a key is inserted into the lock hole of the cylinder lock 5 shown in FIG. 4 and rotated in the unlocking direction, the cylinder lock 5 that has been prevented from rotating in the locked state until then rotates, and The semi-circular cam shaft 18 at the end is rotated. At this time, since the handle 4 is held unrotatable by fitting the vertically elongated ridge 6 of the outer cylinder 4a into the vertically elongated groove 7 of the inner wall of the housing, the key operation can be easily performed by one hand operation. . The rotation of the semi-circular cam shaft 18 pushes down the latch 17 toward the lower position in FIG. 1 against the expanding pressure of the latch spring 20, so that the latch 17 engages with the engaging portion 12. Withdraw from the area.

As a result, the handle 4 that has been released from the holding state at the fitting position up to that point projects leftward in FIG. 1 due to the expanded pressure of the handle spring 21.

As the handle 4 moves in the protruding direction, the latch
17 also moves to the left in the same figure, but the inner cylinder has an engaging action even at the retracted position of the latch 17 at this time.
The latch 17 comes into contact with the engaging portion 4b that comes into contact with the outer peripheral surface of 4a (first
(In the state indicated by the upper chain line in the figure), the protruding position of the handle 4 is restricted to the position indicated by the upper chain line in FIG.

In the protruding state of the handle 4, the previous key operation is changed to the handle knob portion 4c, and the handle knob portion 4c is operated in the turning direction. At this time, the cutout portion 6a of the vertically elongated ridge 6 is changed to the vertically elongated groove of the housing 1. The handle 4 which is located at the outer edge of the handle 6 and which has been released from the automatic blocking state up to then can be rotated.

When the handle 4 is rotated, the locking member 25 is unlocked in the unlocking direction via a joint system such as a joint member 9 which is integrated with the handle 4 in a rotating direction and a sliding contact plate 15 which is connected to the member 9 by a screw 16. Since the handle 4 is rotated, the handle 4 can be opened by pulling it while holding the knob portion 4c.

Then, at the time of closing the door, the knob portion 4c is closed while the knob 4c is still in the previous turning operation position, and then the turning operation is performed in the opposite direction to that at the time of opening the door.
The housing-side receiving member is locked and locked by means of, and the handle 4 is pushed into the housing 1 against the expansion force of the handle spring 21, so that the vertically elongated ridge 6 and the vertically elongated groove 7 are fitted together. The handle 4 can be press-fitted below, and the lower edge of the locking portion 12 that abuts the back inclined surface of the latch 17 in the final region of the operation of the latch 17 resists the biasing force of the latch spring 20. The initial engagement state is maintained by the latch 17 which has been overcome by pushing down and is returned by the urging force of the spring 20.

Therefore, in this closed state, the handle 4 is sufficiently fitted into the housing 1 and does not travel from the door panel surface, and
It is kept in a safe condition without any leverage.

[Effect of device]

As described above, according to the projection handle of the present invention, the structure described in (a) to (c) in the claims makes it possible to form a quadruple tubular structure in which each structural portion is in the lateral position when the handle is fitted, Since the handle protrudes from this state toward the front, the handle mechanism itself can be made as thin as possible, which allows the projection handle of the present invention to be used not only as a normal door handle but also as a steel cabinet. Alternatively, the effect is extremely remarkable when applied to a thin door body made of a steel panel such as a switchboard.
