Abstract

PROBLEM TO BE SOLVED: To provide a handle device for opening and closing door having such configuration that the engagement of a handle and a casing is not released even by the action of a raising spring and capable of forming a substantially large length of the handle to be gripped stably for the opening and closing operations of the handle. SOLUTION: A pushbutton 9 and a locking member 7 are arranged at the most tip and an elastic body for locking 71, a connection member 8, and a lock member 5 are arranged in a storage part 31 at a tip of a handle 2 rising due to the energization of a raising spring 44. Since the connection member 8 is retracted in an unlock condition of the lock member 5, the locking member 7 can be retracted against the energization of the elastic body for locking 71 by pressing the pushbutton 9. Consequently, the engagement of the locking member 7 and a casing 1 with an engaging part 15 is released so that the handle 2 rises by a force of the raising spring 44. Since the connection member 8 is retracted in a lock condition, the locking member 7 cannot be retracted, the release of the engagement with the engaging part 15 becomes impossible, and the handle 2 cannot rise.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a door opening / closing handle device used by being attached to a door of a switchboard storage box or the like.

[0002]

2. Description of the Related Art Conventionally, various inventions such as Japanese Patent No. 2898588 have been proposed as a door opening / closing handle device having a locking / unlocking mechanism used by being attached to a door of a switchboard storage box or the like. As shown in FIG. 10, this device includes a casing 100 attached to a door, and a handle 110. The handle 110 includes a handle body 111, a rotating shaft 112 pivotally supported on the rear end side of the handle body 111, and A lock member 113 having a locking / unlocking mechanism provided near the front end of the handle main body 111, and a push button 114 rotatably provided on the front end side of the lock member 113. The handle device is attached to the bottom surface inside the storage recess 101 provided on the upper surface side of the casing 100 so that the rotating shaft 112 is rotatably fitted. From the stored state to the state raised upward.

When the door is opened by the handle device for opening and closing the door, a key piece is inserted into the lock member 113 and rotated. Thus, the sliding plate 113a provided below the lock member 113 in the handle main body 111 slides rearward, and the sliding movement of the push button 114 is enabled. By pressing the push button 114 downward from this state, the engaging recess 12
1 is disengaged from the locking portion 122 of the push button 114 (this state is illustrated in FIG. 10). Accordingly, the distal end side of the handle 110 is moved by the urging force of the raising spring 115 provided at the connection portion between the handle main body 111 and the rotating shaft 112 so that the housing concave portion 101 of the casing 100 is closed.
It is naturally woken up from above. Then, by turning the raised handle 110, the handle 11 is turned.
0 can be rotated with respect to the casing 100 attached to the door.
The plate-shaped locking metal 120 fixed to the rear end of the rotary member 12 is rotated together. Thereby, the locking between the main body (not shown) such as the switchboard storage box and the locking fitting 120 can be released. By doing so, for example, the push button 114 is not provided, and the key piece is operated as if the tip side of the handle 110 was immediately raised with the rotation operation of the lock member 113 by operating the key piece. Hand holding casing 10
It is possible to prevent the handle 110 from being raised from zero.

The object of the invention of Japanese Patent No. 2898588 is that the locking portion 122 of the push button 114 is rotated by the reaction of the raising spring 115 for raising the handle 110, and the engagement recess 121 of the casing 100 is Is intended to eliminate the risk of disengagement. That is, in the door opening / closing handle device of the present invention, the position of the rotation shaft 116 of the push button 114 and the position of the engaging recess 121 of the casing 100 are on the same line s. As a result, the direction of the reaction of the locking portion 122 of the push button 114 generated by the raising spring 115 is
It works in the horizontal direction passing through the rotation shaft 116. Therefore, the push button 114 is prevented from being rotated by the spring reaction force, and the locking portion 122 is
Since there is no danger that the handle 21 will come off, the handle 1
10 is locked in a state where it is accurately arranged in the storage recess 101 of the casing 100. However, when the rotation shaft 116 of the push button 114 and the engaging recess 121 of the casing 100 are to be positioned on the same line s, the locking portion 122 and the casing It becomes necessary to arrange 100 engaging recesses 121. As a result, only the holding piece 114a projects forward from the handle body 111. On the other hand, since the handle 110 is used to perform opening and closing operations, it is desirable that the entire length L1 of the handle is long. Therefore, it is desirable to arrange the push button 114 at the tip of the handle 110 as in the above-mentioned patented invention. However, in this patented invention, only the holding piece 114a protrudes at the tip of the handle 110. Formally, it can be said that the length L1 of the entire handle including the pressing piece 114a is included. However, in the case of the unstable and thin holding piece 114a, sufficient force for opening and closing operation is not applied, and the length L2 of the portion not including the holding piece 114a (that is, the handle body 111 itself) is substantially reduced. It is the length of the handle.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and has a configuration in which the engagement between the handle and the casing is not released even by the reaction of the raising spring.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a plan view of a door opening / closing handle device according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a sectional view taken along line III-III of FIG.

The door opening and closing handle device of the present invention includes a casing 1, a handle 2, a lock member 5, and a locking mechanism 6. On the upper surface side of the casing 1, a storage recess 11 for a handle is provided. The storage recess 11 for the handle is used to store the handle, and the center of the upper surface of the casing 1 is depressed downward in a substantially square shape so that the upper surface is opened. A circular connection shaft fitting hole 12 is formed on the rear end side of the bottom surface in the handle storage recess 11. The connection shaft 4 is rotatably arranged in the connection shaft insertion hole 12.

After the waterproof packing 14 is mounted on the lower surface of the entire periphery of the casing 1, a handle recess from the upper side is formed in a hole formed in a door (not shown) of a switchboard storage box or the like. 11 is entered. in this way,
With the waterproof packing 14 in contact with the periphery of the door hole, the fixing parts 13a and the bolts 13b,
13b is fixed to the door by being mounted.

The handle 2 includes a handle body 3 and the above-described connection shaft 4 for connecting the handle body 3 and the casing 1. The handle body 3 is attached to the connection shaft 4 so as to be rotatable up and down (up and down) about the shaft pin 43 as a rotation axis, but the rear end side of the handle body 3 extends rearward from the pivot position. When the extended portion comes into contact with the connection shaft 4, the rotation of the handle main body 3 stops in a state of projecting obliquely upward as indicated by a two-dot chain line in FIG. 3. This state is a standing state. Since the connection shaft 4 is rotatably arranged on the casing 1, the handle 2 is rotatable in the lateral direction while being raised on the casing 1. At the tip of the handle body 3,
A storage section 31 for storing the lock member 5 and the locking mechanism 6 is provided. The storage portion 31 projects greatly below the central portion of the handle main body 3 so that the hand can be made hard to slip when the handle 2 is gripped.

A raising spring 44 for raising the front end of the handle body 3 upward from the casing 1 is attached to the shaft support (around the shaft pin 43) between the connection shaft 4 and the handle body 3. I have. The raising spring 44 is formed of a coil spring with feet having two feet and a coil part, and the shaft pin 43 of the connection shaft 4 is passed through the coil part.
The two feet press the connection shaft 4 and the handle body 3 respectively, thereby constantly biasing the handle body 3 upward.

A lock fitting 20 is attached to the lower side of the connection shaft 4, and the lock fitting 20 directly or indirectly engages with a locking portion (not shown) of the door frame. That is, by gripping and turning the handle 2 in the upright state, the connection shaft 4 is rotated, and by this rotation, the locking fitting 20 is disengaged from a locking portion (not shown) of the door frame. The door and the door frame are disengaged.

The lock member 5 is formed of a cylinder lock, and is arranged near the tip of the handle body 3. Lock member 5
Has a locking / unlocking mechanism for performing a locking / unlocking operation such as a protrusion / immersion of a tumbler with a key. An operating portion 51 for moving a communication member, which will be described later, is provided at a lower portion of the lock member 5. When the key is turned at the time of locking, the lock member 5 is turned, and the operating portion 51 is turned. It rotates in the forward direction (tip direction). On the other hand, at the time of unlocking, by rotating the key in the reverse direction, the operating portion 51 rotates in the retreating direction (rear end direction). The lock member may have another lock structure such as a dial lock in addition to the cylinder lock.

Next, the locking mechanism will be described. The locking mechanism 6 locks the handle 2 in a prone state and the casing 1 in a detachable manner, and includes a locking member 7, a coil spring 71 as an elastic body for locking, a connecting member 8, and a pushing member. Button 9
And The members 7, 71, 8, 9 constituting the locking mechanism 6 are arranged together with the lock member 5 in a storage section 31 provided in the handle body 3. The storage section 31 has four walls, an upper surface, a lower surface, and left and right side surfaces, and the front surface is open. In this example, since the push button 9 is arranged at the forefront of the handle 2, the front end portion of the upper surface is also opened so as to be connected to the open front surface. The push button 9 is arranged so as to be exposed at the front end portion and the front surface of the upper surface (see FIG. 4). Further, a circular open portion exposing the upper surface of the lock member 5 is formed near the rear end of the upper surface.

First, the push button 9 will be described with reference to FIGS. The push button 9 is rotatably attached to the handle main body 2 by a shaft 91. More specifically, a shaft 91 is provided on the left and right side surfaces of the storage unit 31, and the rear end of the push button 9 is pivotally supported around the shaft 91, and the front end is rotatable up and down. The upper surface of the push button 9 is a pressing surface 9 for human operation.
The pressing surface 9a is exposed from the front end portion of the open upper surface of the storage section 31. The distal end of the push button 9 is extended downward, and the operating portion 9 for moving the locking member 7
Constituting No. 2. This actuating portion 92 is moved backward (more precisely, by pushing a top surface of the push button 9 by a person).
Downward and backward circular motion). In this example, as shown in FIG. 4, the operating portion 92 is bifurcated and extends downward, and at the center thereof, the distal end locking portion 72 provided at the distal end of the locking member 7 is exposed. I have. Conversely, the open front surface of the storage section 31 is closed by the push button 9 and the locking member 7, and hides the internal lock member 5 and the like to prevent mischief.

As shown in FIGS. 4, 5, and 8, the locking member 7 includes a tip locking portion 72, a passive portion 73 that receives a force from the operating portion 92, and a locking portion such as a coil spring. An elastic receiving portion 74 that receives the force of the elastic body 71 is provided. In this example, the elastic receiving portion 74 is a concave portion suitable for receiving the distal end of the locking elastic body 71 such as a coil spring.
On both left and right sides of the elastic receiving portion 74, a regulated portion 76 for receiving regulation for locking from the lock member 5 is formed. The locking member 7 is provided inside the handle 2 (in the storage section 3).
Within 1), it is slidably arranged back and forth. A guided portion 75 is formed on the locking member 7 so as to stably perform only the movement in the front-rear direction.

In this example, a distal end locking portion 72 is arranged at the center of the distal end of the locking member 7, and a regulated portion 76 and an elastic receiving portion 74 are formed on the rear surface side of the distal end locking portion 72. . A pair of guided portions 75 extend rearward from both left and right sides of the locking member 7. The front end locking portion 72 is formed on the front end surface of the handle recess 11 of the casing 1.
By engaging the handle 5, the handle 2 is maintained in a prone state. In this example, the distal end locking portion 72 is formed as a convex portion and the engaging portion 15 is formed as a concave portion. When the handle 2 is in the prone state, the locking member 7 retreats against the urging of the locking elastic body 71. Then, after retreating, the front end locking portion 72 is moved forward by the urging force of the locking elastic body 71, so that the engaging portion 15
Engage with. On the other hand, even if a force in the direction of raising the handle 2 is applied, the engagement between the distal end locking portion 72 and the engaging portion 15 is not released. As a structure for this purpose, the lower surface of the distal locking portion 72 and the upper portion of the engaging portion 15 are inclined,
The upper surface of 2 and the engaging portion 15 are not inclined.

Next, the guided portion 75 extending rearward is
As shown in FIG. 5, it passes under the partition wall 16 that partitions between the lock member 5 and the push button 9 and reaches both right and left sides of the lock member 5. Therefore, the locking member 7 slides back and forth while being placed on the lower surface of the storage portion 31, but the guided portion 75 extends below the partition wall 16 to extend upward. Cannot rotate. That is, in this example, the lower end of the partition wall 16 constitutes the guide portion 16a that guides the locking member 7 so as to be movable only in the front-rear direction.

As shown in FIGS. 3, 5, and 9, the communication member 8 transmits the locking / unlocking movement of the lock member 5 to the locking member 7, and according to the locking / unlocking movement. Move forward and backward. In this example, a long hole 81 into which the operation part 51 of the lock member 5 is rotatably and slidably inserted is formed, and when the operation part 51 advances by a circular motion with the rotation of the lock member 5, While the operating portion 51 slides in the elongated hole 81, the connecting member 8 is advanced (see FIG. 9A). At the time of unlocking, the connecting member 8 is retracted by the reverse movement (see FIG. 9B). In this example, the lock member 5 is separate from the lock member 5. However, the lock member 5 may be integrated with the lock member 5, or the lock member 5 itself may directly transmit the movement to the locking member 7.

At the front end of the communication member 8, a regulated portion 7
6 is provided, which is in contact with 6 and prevents the retreat. Further, in order to accurately arrange the above-mentioned locking elastic body 71 between the elastic receiving portion 74 and the elastic receiving portion 74,
An elastic support portion 83 is provided. In this example, since the locking elastic body 71 is a coil spring, the elastic body supporting portion 83 is implemented as a shaft inserted into the coil.

Next, how to use the handle will be described. First, starting from the locked state, at the time of locking, the operating portion 51 of the lock member 5 is advanced, and the communication member 8 is also at the advanced position (see FIGS. 6A and 9A). When the restricted portion 76 of the locking member 7 comes into contact with the restricting portion 82 of the contact member 8 that has been advanced, the locking member 7 is also fixed at the advanced position. It is in a state engaged with the portion 15. In this state, even if the push button 9 is pushed in, the locking member 7 does not retreat and the handle 2
Does not happen.

When the lock member 5 is unlocked, the operating portion 51 of the lock member 5 is retracted, and the communication member 8 is also retracted (FIG. 5,
FIG. 9B). Due to this retreat, the contact between the restricting portion 82 of the communication member 8 and the locked portion 76 of the locking member 7 is released,
The locking member 7 can be retracted. However, the elastic body 71 for locking
Is urging the locking member 7, the locking member 7 remains at the forward position, and the engagement with the engagement portion 15 of the casing 1 is maintained.

From this state, as shown in FIG.
When the push button 9 is depressed, the operating portion 92 moves rearward, and pushes the passive portion 73 of the locking member 7 rearward. Thereby, the locking member 7 resists the urging of the locking elastic body 71,
fall back. As a result, the engagement between the distal end locking portion 72 and the engaging portion 15 of the casing 1 is released, and the handle 2 is raised by the action of the raising spring 44. By turning the handle 2 that has been raised, the locking fitting 20 is disengaged from a locking portion (not shown) of the door frame, and the door can be opened. When turning the handle 2, it is necessary to squeeze the handle 2 strongly. Here, a push button 9 is provided at the tip of the handle body 2.
Since the storage portion 31 for storing the lock member 7 and the lock member 5 is formed, the entire storage portion 31 can be used as a handle grip, and the handle 2 can be strongly gripped. In addition, since the distal end surface of the storage portion 31 is open, and the distal end surface of the push button 9 and the distal end locking portion 72 are arranged in an exposed state on the opened distal end surface, this grip is achieved. The size of the housing portion 31 can be made as large as possible, and it is possible to have a firm grip. In particular, in this example, the left and right side surfaces of the storage section 31 cover the left and right sides of the push button 9, so that only the unstable push button 9 does not protrude from the storage section 31 and the grip can be grasped. Instability can be eliminated.

Conversely, when the handle 2 is lowered, the handle 2 is rotated downward against the bias of the raising spring 44. Then, since the lower surface of the distal end locking portion 72 of the locking member 7 and the upper portion of the engaging portion 15 are inclined, the locking member 7 retreats against the urging of the locking elastic body 71. Then, the distal end locking portion 72 engages with the engaging portion 15. At this time, if the push button 9 and the locking member 7 are integrated, the raising spring 4
Due to the action of 4, there is a possibility that the engagement between the two 72 and 15 is released. However, in the handle of the present application, since the push button 9 and the locking member 7 are separate bodies, there is no possibility that the engagement is released. More specifically, the raising spring 44 urges the handle 2 in a direction to raise the entire handle 2, and the force is received at the engagement portion between the distal end locking portion 72 and the engaging portion 15. The urging force of the raising spring 44 causes the rear end side of the locking member 7 to receive a force in a direction of turning upward with the engagement portion as a fulcrum. However, the guided portion 75 on the rear end side of the locking member 7 passes under the partition wall 16 and extends rearward, so that it cannot rotate upward. In this example, the guided portion 75 of the locking member 7 abuts on the lower end of the partition wall 16, thereby preventing the rotation of the locking member 7. As a result, the locking member 7 does not rotate, and the engagement between the distal locking portion 72 and the engaging portion 15 does not come off.

Further, according to the present invention, the push button 9 is of a rotary type, and by this rotation, the locking member 7 can be easily retracted by pushing the locking member 7 rearward. By pressing 9, the engagement with the engagement portion 15 can be reliably released. In particular, in this example:
The push button 9 has a square bracket shape ("shape") in a side view, in other words, the rear end of the push button 9 is pivotally supported,
The distal end is rotatable up and down, and the distal end of the push button 9 is extended downward to form an operating portion 92 for moving the locking member 7. Therefore, when the upper surface of the push button 9 is pushed downward and turned, the operating portion 92 is located at a position extending downward from the distal end side, so that the amount of backward movement is greater than the amount of downward movement. Become. As a result, the locking member 7 can be easily retracted.
Therefore, even if the handle rusts due to long-term use, pressing the push button 9 allows the locking member 7 to be pressed.
Can be retracted.

As described above, the present invention is not limited to the above-described embodiment. For example, the present invention can be implemented as a handle without a lock without using the lock member 5. Also,
The present invention can also be implemented as a type that does not rotate only by allowing the handle to be raised and lowered. Further, the push button 9
It is most advantageous to arrange the handle 2 at the tip of the handle 2 in order to lengthen the length of the handle 2. .

[0028]

As described above, the first invention of the present application has a structure in which the engagement between the handle and the casing is not released by the reaction of the raising spring, and at the same time, the opening and closing operation of the handle is stable. The present invention has been able to provide a door opening / closing handle device capable of forming a substantial length of a handle that can be gripped by gripping. According to the second and third aspects of the present invention, in addition to the effects of the first aspect described above, the push button allows reliable and smooth engagement and disengagement between the handle and the casing. And a door opening / closing handle device capable of securely locking and unlocking the door. In particular, in the second invention, a storage portion for storing the push button, the locking member and the lock member is provided at the distal end of the main body of the handle, and the distal end surface of the storage portion is open. The push button and the locking member can be positioned at the forefront of the handle body because the push button and the locking member are arranged in a state where the distal end surface of the push button and the distal locking portion are exposed on the set distal end surface. Accordingly, the substantial length of the handle that can be stably gripped can be formed as long as possible. In the third invention of the present application, since the communication member is arranged between the locking member and the locking member, even if the position of the locking member and the locking member is far apart, the locking by the communication member is performed. -The unlocking operation can be transmitted to the locking member.
