Description

  The present invention relates to a snap-on tablet. More specifically, the present invention relates to a snap lock used for a lid of a flashlight device.

  Generally, a fastener called a snap lock is used as a locking means used when temporarily locking a case main body and a lid, etc. in a housing so as not to separate each other.

  A conventional snap lock includes a pedestal fixed in the vicinity of the end of the case body in the case, a lock bearing provided on the pedestal, and a lock bearing that is rotatable about the lock shaft attached to the lock bearing. The open / close lever attached to the open / close lever, the joint attached to the open / close lever so as to be rotatable about the lever shaft attached to the center of the open / close lever, and the key at the tip of the joint fixed near the end of the lid It is comprised from the hook which meshes with a part. In this snap lock, the case main body and the lid can be locked so as not to be separated from each other by engaging the key portion of the joint with the key portion of the hook and tilting the opening / closing lever toward the case main body side. In addition, the case body and the lid can be separated and the lid can be opened by pulling the open / close lever that is tilted toward the case body side to release the meshing of the joint and the hook.

  In general, a snap lock is sometimes used to lock a case main body and a lid in a housing in an apparatus, particularly an electric device. In this device, it is necessary to open a part of the casing and look inside to perform an internal inspection, replace parts, or change settings during the operation period. In order to increase the work efficiency of this inspection and the like, it is necessary to be a snap lock that securely locks the case and lid of the housing by an easy operation.

  For example, in Patent Document 1, by having a hinge mechanism in which a hole for moving a hinge shaft is provided in a lock bearing, the movable range of the separated case body and lid is defined as the range in which the hinge shaft operates within the hole. Since it can be restricted to the direction of rotation around the hinge axis, it describes a snap lock that can be used as a hinge part of a housing or the like.

  Patent Document 2 describes a snap lock comprising a pedestal, an opening / closing lever that is rotatably supported by the pedestal, and a locking lever that is rotatably supported by the opening / closing lever. In the technique of Patent Document 2, when the open / close lever is closed to the pedestal side in the lock means for locking the front end of the base and the front end of the open / close lever when the snap lock is closed, the relief lever is engaged. The stop portion engages with the locking portion of the base. The relief lever is always urged by the torsion spring in the direction of engagement with the locking portion of the pedestal, so that even if a force in the unlocking direction is unexpectedly applied to the lever portion of the opening / closing lever, the opening / closing lever opens. Can be prevented.

  As a fixing mechanism other than a snap lock, for example, in the structure of a rotation / tilt base on which a display device is mounted, a knob that slides left and right manually by sliding the upper end of an inverted T-shaped lever into a long hole is slid Patent Document 3 discloses a rotation / fixing mechanism that allows the base and the display device to be fixed and moved.

In addition, in the lock for the door of the opening / closing device, there is a lock mechanism by a bar lock in which a recess is formed in which the outer lid accommodates the swing lever so that the swing lever can be sunk with respect to the use of the bar lock as the swing lever lock. (Patent Document 4).

  However, in the snap lock of the related technology described above, if the force is unexpectedly applied in the opening direction of the open / close lever, the open / close lever opens and the snap lock is loosened, and a gap is opened between the case body of the housing and the lid. is there. In addition, the joint of the snap lock may come off and the lid may open. As in Patent Document 2, when a means for locking so that the open / close lever is not raised is provided, the snap lock has a complicated structure. There is also a problem that the open / close state of the open / close lever can be confirmed only nearby.

  The present invention is particularly assumed to be applied to a case main body and a lid in a housing of a flashlight device or the like. For example, a flashlight is provided in a very high structure such as a steel tower, a chimney, a suspension bridge pier, or a light guide of a runway, and always emits a flash to inform an aircraft or the like of its position. Since the flashlight always operates, maintenance such as periodic replacement of the bulb is necessary. Furthermore, since rainy weather is exposed to rain, a rainproof structure is required.

  When performing maintenance work on the flashlight, it is necessary to work in a narrow outdoor space, so it is required to open and close the flashlight case body and lid with a simple operation in order to shorten the work time and work safely. The In addition, for example, when the operator's tool suddenly touches the snap lock when the maintenance work is finished, if the force is applied in the opening direction of the opening / closing lever, the opening / closing lever remains open. End up. Then, a gap is formed between the case body of the flashlight and the lid, and rain enters the flashlight.

  Therefore, it is desired to lock the opening / closing lever with a simple structure so that the opening / closing lever does not open even when an unexpected force is applied in the opening direction of the opening / closing lever of the snap lock. It is also desirable that the state where the open / close lever is locked can be visually recognized from a remote position.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a snap lock that does not open the open / close lever from a locked state unless an operation other than the opening operation of the open / close lever is performed.

In order to achieve the above object, a snap lock according to the first aspect of the present invention is provided.

2A to 2C are plan views of the snap lock 4 according to Embodiment 1 of the present invention, and FIGS. 3A to 3C are side views of the snap lock 4 of FIGS. 2A to 2C. 2A and 3A, FIG. 2B and FIG. 3B, and FIG. 2C and FIG. 3C correspond to each other. 2A to 2C and FIGS. 3A to 3C will be described, and the structure of the snap lock 4 according to the first embodiment and the operation when opening and closing will be described. In order to facilitate understanding of the snap lock 4, the illustration of the flashlight housing 1 is omitted below.

  2A and 3A are a plan view and a side view showing the snap lock 4 in a state where the opening / closing lever 6 is largely opened. As shown in FIG. 3A, the snap lock 4 is attached to a lock bearing 10 provided on the pedestal 5, a lock shaft 11 attached to the upper portion of the lock bearing 10, and a pivotable shaft about the lock shaft 11. The opening / closing lever 6 provided, the joint 7 provided rotatably about the rotation shaft 12 provided on the opening / closing lever 6, and the hook 8 engaged with the joint 7 are provided. A rotating shaft 13 is fixed to the pedestal 5, and includes a rotating rod 14 that is rotatably attached to the rotating shaft 13. The rotating rod 14 is provided to lock the opening / closing lever 6 and the base 5. As shown in FIG. 2A, the rotation shaft 13 is substantially parallel to the direction in which the opening / closing lever 6 is opened at the position where the opening / closing lever 6 is closed. Further, the rotating rod 14 can be rotated around the rotating shaft 13 in both clockwise and counterclockwise directions.

  2B and 3B are a plan view and a side view showing a state in the middle of closing the opening / closing lever 6. As shown in FIG. 3B, the tip of the joint 7 is hooked on the hook 8, and the open / close lever 6 is closed to the base 5 side. At this time, the opening / closing lever 6 rotates around the lock shaft 11. The rotating shaft 12 of the joint 7 rotates around the lock shaft 11 around the lock shaft 11 of the opening / closing lever 6. As a result, the hook 8 hooked on the tip of the joint 7 is drawn to the base 5. As shown in FIG. 2B, when the rotary rod 14 is parallel to the longitudinal direction of the opening / closing lever 6, it does not interfere with the opening / closing operation of the opening / closing lever 6, so the opening / closing lever 6 can be freely opened and closed.

  2C and 3C are a plan view and a side view showing a state in which the opening / closing lever 6 is closed and locked by the rotating rod 14. As shown in FIG. 3C, after the open / close lever 6 is closed to the pedestal 5 side, the rotating rod 14 is rotated. As shown in FIG. 2C, the rotating rod 14 comes into contact with the upper surface of the opening / closing lever 6 when substantially perpendicular to the longitudinal direction of the opening / closing lever 6. At this time, even if a force is applied in the opening direction of the opening / closing lever 6, the rotating rod 14 is caught by the opening / closing lever 6, so the opening / closing lever 6 does not open. Therefore, the opening / closing lever 6 can be locked in a closed state or can be freely opened and closed depending on the direction of the rotating rod 14. In order to unlock the snap lock 4, the procedure reverse to the above, that is, the rotating rod 14 is rotated to a position parallel to the opening / closing lever 6, and then the opening / closing lever 6 is opened.

  As described above, in the snap lock 4 according to the first embodiment, after the opening / closing lever 6 is closed to the pedestal 5 side, the opening / closing lever 6 is rotated by rotating the rotating rod 14 so as to be orthogonal to the opening / closing lever 6. Lock it so that it does not open. As a result, even if a force is applied to the opening / closing lever 6, it does not open. In order to open the opening / closing lever 6, the rotating rod 14 must be rotated to release the locked state, so that it is possible to prevent the opening / closing lever 6 from being accidentally opened. In addition, it is possible to confirm the open / closed state of the snap lock 4 by visually recognizing the direction of the rotary rod 14 even from a remote location.

(Embodiment 2)
The snap lock 4 according to the second embodiment is provided with a recess in a portion where the rotating rod 14 is engaged. 4A is a plan view of the snap lock 4 according to Embodiment 2, and FIGS. 4B and 4C are side views of the snap lock 4 according to Embodiment 2. FIG. The snap lock 4 according to the present embodiment is different from the first embodiment in that the recess 15 into which the rotating rod 14 is fitted is different from the first embodiment, and other configurations are the same as those in the first embodiment.

  As shown in FIG. 6C, the rotating rod guiding portion 17 formed on the opening / closing lever 6 is formed in a convex shape toward the rotating shaft 13 of the rotating rod 14. A recessed portion 15 into which the rotating rod 14 is fitted is formed at the uppermost portion of the rotating rod guiding portion 17. As in the third embodiment, a spring 16 is provided between the rotating rod 14 and the rotating shaft 13 to urge the rotating rod 14 toward the base 5.

  As shown in FIG. 6D, when the rotating rod 14 is rotated from an azimuth angle orthogonal to the longitudinal direction of the opening / closing lever 6 to a parallel azimuth angle, both ends of the rotating rod 14 are moved upward along the slope of the rotating rod guiding portion 17. Therefore, the rotating rod 14 is pushed up toward the tip of the rotating shaft 13 against the biasing force of the spring 16. Then, when the rotating rod 14 is parallel to the longitudinal direction of the opening / closing lever 6, the rotating rod 14 is engaged with the uppermost recess 15 of the rotating rod guiding portion 17. In this state, since the opening / closing lever 6 is locked to the rotating rod 14 via the spring 16 and the rotating rod guiding portion 17, the opening / closing lever 6 does not open even if a force is applied to the opening / closing lever 6. Since the rotating rod 14 is biased in the direction to engage with the recess 15 of the rotating rod guiding portion 17 by the elastic force of the spring 16, the rotating rod 14 is slightly rotated by vibration or the like as in the third embodiment. However, it returns to the bottom of the recess 15 and maintains a stable locking state.
