Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a handle device for opening and closing which serves as a pull when opening and closing a door or the like of a storage case of a switchboard.

[0002]

[Prior art]

 Conventionally, this type of handle has been widely used as a pull attached to the front of a door of a storage case of a switchboard, etc., and is always arranged substantially flush with the front of the door. It is used as a pull-up handle. The opening / closing handle has the function of engaging and disengaging the door from a door support such as a case, and fixing the door in a closed state, in addition to the function as a simple pull handle and the function as a pull handle. And those with a function to lock the door closed.

[0003] These opening / closing handle devices include a handle which can be raised and lowered so that a tip side protrudes upward from the casing, and a casing provided with a concave portion for storing the handle and provided on a door. There are a type in which the locking state between the handle and the casing is released by pressing a separate or provided push button provided on the handle, and a type in which such a push button is not provided. Those having push buttons are found in, for example, Japanese Utility Model Publication No. 6-36200 and Japanese Patent Application Laid-Open No. 8-232512.

[0004] As a device without a push button, a device has been proposed in which the handle can be raised and lowered, locked and unlocked only by operating the handle. Such a handle device having no push button is more advantageous than a handle device having a push button in terms of simplicity of operation and a cleaner appearance around the handle to improve appearance. However, in many cases, the function of fixing the door in the closed state is also used as the function of locking the door in the closed state, in order to pursue appearance and compactness, so the door is closed without locking. There are few things that can be fixed in a state, that is, simply locked before locking. If the lock between the handle and the casing is completed for the first time by locking the lock unit, there is no way to stop the handle in the recess of the casing until it is locked, so it must be pressed by hand, and At this time, it is difficult to see if the handle is locked down where locking is possible, and the handle is not locked down until the handle is lockable. May not turn. Further, it is inconvenient to have no means for easily locking the handle and the casing at the time of temporary opening / closing, which does not need to be locked one by one.

[0005] In addition to the locking, even if the locked state / unlocked state can be achieved only by operating the handle, a structure for such locking is provided on the base shaft side of the handle. Most are equipped with. This is because, in order not to impair the appearance and compactness, it is necessary to avoid providing a locking mechanism at the distal end of the handle provided with the locking mechanism. Such examples include those found in Japanese Patent No. 2,504,714 and JP-A-6-240930.

[0006] As described above, in the case where the locking mechanism is provided on the base shaft side of the handle, although various measures are taken, the stability and reliability of the locking operation are determined by holding the push button described above. Inferior to one. This is due to the fact that those with push buttons have a locking mechanism on the handle tip side where the operation (rotation moment) is larger than the handle shaft side. In the case of Japanese Patent No. 2,504,714 and Japanese Patent Application Laid-Open No. 6-240930, it is necessary to press the base end of the handle to raise the handle to release the lock. Pressing near the base end where the moment is small requires force and is troublesome.

[0007] For this reason, it is possible to easily and smoothly obtain a smooth, reliable and stable locking and unlocking operation of the handle and the casing before locking without increasing the size of the handle device and requiring no force. If this is the case, it is inevitable to select a device having the above-mentioned push button, which is inferior at present, or a device having a release means similar to the push button.

[0008]

[Problems to be solved by the invention]

 The first invention of the present application is that the locking mechanism is provided with a separate locking mechanism, and the locking and unlocking state can be achieved by only a single operation of pushing a specific portion of the handle. The handle device, which has excellent and beautiful appearance, does not have a push button, has a reliable and stable locking operation, and furthermore, the locking operation and the unlocking operation are realized only by pushing the handle at the same position. Thus, the above-mentioned problem is solved. The second invention of the present application aims to solve the same problem as the first invention of the present application, particularly assuming that the operation during locking / unlocking of the handle is stabilized. The third invention of the present application solves the same problem as the first invention of the present application described above, while enabling the locking mechanism to be realized with a simple structure and a configuration that is easy to attach.

[0018] The locking means and the configuration around the locking means will be described in more detail. As shown in FIG. 3, a guide body 8 and a cover 21 are provided on the front B side of the locking device 6, that is, on the front side 2b. The cover 21 is a member provided integrally with the handle 2 so as to cover the front side 2b (is immovable with respect to the handle 2). As shown in FIG. 4A, the cover 21 is a plate-like body having a substantially rectangular front surface (a surface facing the front B side), and a guide shaft 21a and a guide shaft 21a on the rear surface (a surface facing the rear C side). Inclined portion 21b (see FIG. 5 (A). Note that FIG. 5 (A) will be used later for describing the operation of the locking means, but since the rear side of the cover 21 is shown, please refer to this first.) And a notch 21c. In addition, an insertion portion 21d is provided, which cuts upward from the lower surface of the covering 21 and penetrates from the front surface to the rear surface thereof. The notch 21c of the cover 21 is a notch formed from the rear surface of the cover 21 to the side thereof. The guide shaft 21a is a cylindrical shaft that protrudes rearward from the rear surface of the cover 21. The guide inclined portion 21b is provided at a lower portion of the rear surface of the cover 21, and is a triangular prism-shaped projection having a substantially right-angled triangular cross section that projects rearward (FIG. 5A).

The guide body 8 is a plate-shaped metal fitting as shown in FIG. The periphery of the guide body 8 has a substantially hook-like contour. Numeral 85 indicates a tip of a hook provided by the guide body 8. The hook 81 is provided inside the hook w, and the guide 80 is provided outside the hook w. The locking portion 81 is the lowermost portion (the deepest portion) inside the guide body 8. Further, a relief portion 82 is formed adjacent to the locking portion 81 on the side opposite to the hook point 85. The relief portion 82 is an inclined surface that gradually retreats from the retreating direction y that retreats from the front side portion 2b of the handle 2, that is, the rear C side in this example, in the direction opposite to the retreating direction y, that is, forward B. The tip of the inclined surface presented by the relief portion 82, that is, the portion that protrudes forward B is positioned right beside the locking portion 81 (the same position in the front-rear direction). A rear protruding portion 84 is formed on the rear side (the surface facing the rear C side) of the guide body 8. The guide body 8 is provided with a hole 83 penetrating from the front B to the rear C on the base side of the hook. The guide body 8 is loosely fitted to the guide shaft 21 a of the covering body 21 through the hole 83.

After the guide body 8 is loosely fitted, the coil spring 9 is mounted on the guide shaft 21a of the covering body 21 as main biasing means (FIG. 3, FIG. 5A). In this state, the coil spring 9 exerts an elastic force toward the front and rear in the axial direction (front B and rear C), and also moves along the front side 2b in the rotation direction around the guide shaft 21a. Exercise. One end of the coil spring 9 is fixed to the notch 21c of the cover 21, and the other end is hooked on the rear projecting portion 84 of the guide 8 (FIG. 5A). At the rear of the guide shaft 21a, a groove is formed on the peripheral surface of the guide shaft 21a. A washer 22 is mounted in this groove to prevent the coil spring 9 from dropping off the guide shaft 21a. The guide body 8 is urged by the coil spring 9 in a direction away from the washer 22, that is, toward the rear surface of the cover 21. At this time, the guide body 8 is also urged by the coil spring 9 in a direction along the rear surface of the covering body 21, and the urging causes the guide portion 80 to contact the side surface (inclined surface) of the guide inclined portion 21 b. Touch

The contact member 7 is a pin that penetrates into the housing recess 11 of the casing 1 from the front of the casing 1 as shown by a broken line in FIG. Such a pin is used as the contact body 7 and is fixed to the casing 1 by press-fitting. It can be easily formed. Further, by forming the cover 21 to be detachable from the handle 2, the guide body 8 can be easily detached from the side of the handle 2. However, it is also possible to use another fixing tool, such as a screw or a rivet, that can form a projection, other than the pin, for the contact body 7.

Next, with reference to FIGS. 5 and 6 (A) to 6 (F), a state in which the handle 2 is disengaged from the casing 1 will be described. In order to avoid complication of the drawings, FIGS. 5A to 5D mainly show the contact member 7 and the guide member 8 (two-dot chain line) constituting the locking means, and the covering member 21 and the main body. Only the coil spring 9 as a biasing means is illustrated, and other members are omitted. 6 (A) to 6 (F) show only the front end of the contact body 7 and the front surface of the guide body 8 when viewing the rear C from the front B.

First, the locking operation will be described. When the handle is pressed from the upright state (see FIG. 2) toward the casing 1 and the handle 2 enters the storage recess 11, the side surface (peripheral surface) of the contact portion 7 as shown in FIG. , The guiding portion 80 of the guide body 8 descends. Due to this descent, as shown in FIG. 5A, the contact portion 7 relatively enters the insertion portion 21d from the lower surface of the cover 21 and projects the tip from the insertion portion 21d to the surface of the cover 21. (For convenience of explanation, it is assumed that the handle 2 side is fixed and the contact portion 7 moves with respect to the handle 2).

[0024] With the pushing operation of the handle, the contact portion 7 moves upward along the insertion portion 21d. By this movement, as shown in FIG. 6 (B), the contact portion 7 follows the guide portion 80 of the guide body 8 against the bias of the coil spring 9, and moves the guide body 8 to the front side of the handle. It is rotated in the direction along 2b (the rear surface of the cover 21), that is, in the lateral direction x. Thus, the guide portion 80 of the guide body 8 is pushed up by the contact portion 7.

With the operation of the handle 2, the contact portion 7 moves further upward, and as the rotation of the guide body 8 proceeds, as shown in FIG. After straddling, the guide once moves from the hook 85 of the guide body 8 to the sub-guide portion 87 on the base side of the guide body 8. When the downward movement of the handle 2 is completed, the guide body 8 is in a lying state, and is not pressed by the contact portion 7 as shown in FIG. Then, it rotates in the opposite direction to the above and returns to the original state. At the same time, as shown in FIG. 6D, the contact portion 7 enters the pocket w. The side surface of the contact portion 7 corresponds to the side portion of the relief portion 82, and both are kept in contact with each other by the bias of the coil spring 9.

When the handle 2 is turned down and the pressing is completed, the contact portion 7 is hooked on the locking portion 81 by the elasticity of the elastic body 3, and the two are in contact with each other (the state shown in FIG. 5C). , The engagement between the handle 2 and the casing 1 is completed.

Next, the unlocking operation will be described. When the handle 2 in the locked state is pressed again, the handle 2 can be pushed deeper (downward) into the storage recess 11 by the play above and below the pocket w of the guide body 8. At this time, from the locked state shown in FIGS. 5C and 6D, as shown in FIG. 6E, the contact portion 7 moves further upward in the pocket w of the guide body 8. I do.

Since the shape of the relief portion 82 is such that the shape of the relief portion 82 retreats backward C as it goes upward, finally, as shown in FIG. The front end (the foremost end) of the contact portion 7 comes into contact with the front surface (the surface facing the front B side) of the relief portion 82 which is an inclined surface.

At the end of pushing the handle 2, the handle 2 tries to move upward due to the elastic force of the elastic body 3. As a result, the contact portion 7 moves downward, and as shown in FIG. 5 (D), the tip (most end) of the contact portion 7 moves downward on the front surface of the relief portion 82 which is an inclined surface. Imitate towards. The guide 8 pushed by the tip of the contact portion 7 is pushed away in the retreating direction y of the handle front side portion 2b, that is, in the rear C side. The contact portion 7 that follows the front surface of the escape portion 82 has no obstruction, so it moves downward and separates from the guide body 8 to be in the state of FIG. 5A and FIG. 6A. The handle 2 is in an upright state (FIG. 2).

The locking device 6 shown in FIG. 3 and its locking / unlocking operation will be described. The locking device 6 is composed of a lock body 61 capable of performing a locking operation by inserting a key (not shown) from above, and a separate lock plate 63 arranged below the lock body 1. . As the lock body 61, a conventional lock body having a locking mechanism therein can be used as appropriate. In this example, a lock body provided with an operating portion 62 that moves forward and backward by an arc motion by a locking and unlocking operation is provided below the lock body 61. The lock plate 63, which can be moved back and forth by the movement of the operation unit 62, is connected to the operation unit 62. As shown in FIG. 4C, the lock plate 63 is provided with a connection hole 64 extending in the front-rear direction, and a contact abutting portion 65 in front of the connection hole 64.

As shown in FIGS. 6G and 6H, inside the handle 2, the lock main body 61 is fixed to the handle 2, and a lock plate 63 below the lock body 61 is arranged so as to be able to move left and right. Have been. In this state, the operating portion 62 is disposed in the connection hole 64 (this is the connection described above). When the operating part 62 moves forward and backward by the circular motion, the operating part 62 moves left and right in the connection hole 64 and moves the lock plate 63 forward and backward. FIG. 6 (G) shows the locked state, and FIG. 6 (H) shows the unlocked state. This locking / unlocking operation can be performed when the handle 2 is in the locked state (see FIGS. 5 (C) and 6 (D)). In the locked state, the lock plate 63 is moved by the left hand in FIG. 6 (G) so that the abutment portion 65 abuts on the rear end of the rear protruding portion 84 of the guide body 8 to move the guide body 8 backward. Block. This is in the locked state. When the lock is released, the lock plate 63 moves to the right hand, and the abutment portion 65 is separated from the rear projecting portion 84 of the guide body 8. As a result, the guide body 8 can be moved backward. The locking / unlocking mechanism can be changed to a known mechanism other than the above.

Lastly, the rotator 42 is briefly described. In this example, the rotator 42 is formed in a plate shape as a whole. As shown in FIG. 7, an engaging portion 43 used to directly engage the door and the support of the door is formed on the rotating body 42 and indirectly connected to the door. As means for engaging with the support of the door, connection portions 44 for connecting an operation rod (not shown) are formed at two places. The connecting portions 44 are formed on two protruding portions 45 extending outward of the rotating body 42. The protrusions 45 have a function as angle restricting means for restricting the rotation angle of the rotating body 42. Specifically, an outer peripheral wall 13 that covers the outer periphery of the rotor 4 is provided at a lower portion of the casing 1. The outer peripheral wall 13 is engaged with the protrusions 45, 45 to stop the rotation of the rotating body 42. A rotation restricting engagement portion 14 is provided. In this example, the rotation restricting engagement portion 14 is provided so as to protrude downward from the outer peripheral wall 13 and come into contact with the protruding portions 45, 45. It is restricted within the angle between 45,45. As described above, since the protruding portions 45, 45 also have a function as angle restricting means for restricting the rotation angle of the rotating body 42, the rotating body 42 of this embodiment can be reliably formed with a simple configuration. It has the advantage of being able to perform precise angle adjustment, and can be manufactured at low cost, and is easy to assemble.

In the above example, the contact body 7 is fixed to the inner side surface of the storage recess 11, and the guide body 8 moves with respect to the contact body 7 to change the contact position. However, conversely, the present invention can be implemented if the contact member 7 moves with respect to the guide member 8 to change the contact position. Further, the guide body 8 is provided on the front side 2b of the handle 2, but may be provided on any of the left and right sides 2c and 2d (not shown). In contrast to the above-described embodiment, the present invention can be implemented even if the guide body 8 is provided on the inner side surface of the storage recess 11 and the contact body 7 is provided on the handle 2 side. (Not shown).

[Effect of the invention]

 According to the first and second inventions of the present application, the locking mechanism is provided with a separate locking mechanism. The locking and unlocking state is achieved only by operating the handle without the push button. For a handle device with excellent compactness that can be performed, a secure and stable locking operation is obtained by the guide of the locking means, and furthermore, the locking operation and the unlocking operation are pushed in at the same position of the handle. Only realized. That is, instead of providing the locking means on the base shaft side of the handle, a contact body and a guide body constituting the locking means are provided on the side portion of the handle and the storage recess. The contact body and the guide body having such a positional relationship abut against each other so that one guides the other, thereby enabling reliable guiding of the locking operation. In particular, the second invention of the present application is the part farthest from the handle shaft side, that is, the part where the handle has the largest motion (large rotation moment), while obtaining the effect of the first invention of the present application. Since the main part of the structure of the locking means is provided on the front side of the handle, the locking and unlocking operations are extremely stable as compared with the case where the locking means is provided at another part of the handle. In the third invention of the present application, it is possible to select the locking means having a simple structure and a structure that is easy to attach, while obtaining the effects of the first or second invention of the present application.
