At the time of unlocking, the latch is released by pushing the latch lever 3 by two fingers, and the opening/closing lever 1 is opened. Since the catch lock is made thin and can be imbedded in the side of the bag or the like, the bag or the like can be prevented from opening by hitting an object. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  TECHNICAL FIELD The present invention relates to a double knob snap lock that closes and fixes a lid of a bag, and particularly relates to a double clamp snap lock that releases a latch for maintaining a locked state by pressing the knobs on both sides.

  Conventionally, there is a snap lock as a type of lock attached to a bag such as a suitcase. For a snap lock, hang a latch on the main body side of the bag on a receptacle fixed to the lid of the bag, pull the latch by tilting the open / close lever connected to the latch toward the main body side, and pull the lid on the main body side. It is a lock that is tightened and fixed to. When opening the lid, raise the open / close lever and remove the latch from the receiving part. Since the snap lock is basically only tightened by a spring, the opening / closing lever may be lifted by an accidental external force and the lid may be opened. In order to avoid this, there is one in which the opening / closing lever is latched. Such a conventional snap lock will be described with reference to FIG.

  Fig.7 (a) is a figure which shows the state before closing the lid of a bag and locking. A receptacle is fixed to the lid of the bag. A pedestal is fixed to the main body side of the bag. An opening / closing lever is attached to the base via a link. There is a latch at the end of the opening / closing lever on the lid side, and a movable rod is provided at the end of the main body side. There is a fixing rod at the end of the pedestal on the main body side. FIG.7 (b) is a figure which shows the state which latched the latch of the opening-and-closing lever on the receiving lever. When the end of the open / close lever on the main body side is pressed in this state, the movable rod hits the fixed rod, and the movable rod engages with the fixed rod while retracting toward the center of the open / close lever, resulting in the state shown in FIG. . In this state, since the movable rod is pushed toward the end of the opening / closing lever on the main body side by the elasticity of the spring, the movable rod does not come off the fixed rod.

  When opening the lid, when the push button at the end of the movable rod on the main body side is pressed, the movable rod is detached from the fixed rod and the state shown in FIG. 7B can be obtained. Further, by removing the latch from the receiving rod, the state shown in FIG. 7B is obtained, and the lid can be opened. Even if an accidental external force or vibration is applied to the open / close lever, the latch does not come off carelessly, so the lid can be securely closed. In addition to this example, there are those that release the latch by pressing the push button on the side of the open / close lever, and those that release two latches by pressing the push buttons on both sides. Below are some examples of prior art related to this.

  The “holding lock” disclosed in Patent Document 1 is simple in appearance and simple in both engagement and disengagement operations. As shown in FIG. 8 (a), a locking member is slidably connected to the lock body by a link, and a torsion coil spring is provided to urge the locking member to a disengaged position where the locking member is always lifted and advanced. Further, the lock body is provided with an operating member having an engaging portion that engages with a locking claw of the locking member so as to be slidable in the lateral direction, and a spring that constantly biases the operating member outward. In a normal state, the locking member does not obstruct the opening and closing of the lid. The locking operation can be performed by a series of simple operations of the locking member. The release operation can be performed by a one-touch operation of pinching the operation member. Since only the locking member is visible when engaged, the appearance is very simple.

  The “trunk lock” disclosed in Patent Document 2 smoothly and securely locks the locking plate of the lock main body attached to the lid side of the trunk body and the hook provided on the main body side. Is designed to prevent accidental removal. As shown in FIGS. 8B and 8C, a horizontal pivot shaft is passed to the substrate fixed to the lid side of the trunk body, and the lower end of the lock body is pivotally attached to the pivot shaft. The pivot shaft is passed through a pair of left and right "<"-shaped holes formed in a locking plate that engages with a flange provided on the main body side. The horizontal axis passed to the upper end of the locking plate is passed through the bending hole of the support piece provided on the substrate. The lock body and the horizontal axis are connected by a connecting piece. The release operation can be performed by pressing the operation panel.

  The “patching lock” disclosed in Patent Document 3 is used as a lid stopper for a casing such as a trunk or a bag, and is prevented from being inadvertently unlocked by an impact. As shown to Fig.9 (a), a base is fixed to a housing | casing. The open / close lever is rotatably supported on the pedestal. The locking lever is rotatably supported by the opening / closing lever. When a locking means is provided and the lid is closed with a snap lock, the tip of the base and the tip of the open / close lever are locked. The release operation can be performed by pushing the lock release operation portion of the relief lever that is on the open / close lever.

  The “latch device” disclosed in Patent Document 4 can be used with high reliability by preventing the locking lever from being accidentally released by preventing the operation lever from floating and rotating due to the collision of other objects. It is what I did. As shown in FIG. 9B, a hook lever is connected to the bearing plate portion of the base plate by a pivot. A receiving hole through which the hook portion of the hook lever enters and exits is formed at the tip of the operation lever. In the latching locked state, the hook lever is biased in the rotational direction by the spring so that the hook portion engages with the edge of the receiving hole of the receiving hole. The release operation can be performed by pressing the hook portion.

  The “over center latch” disclosed in Patent Document 5 is used for closing a lid or a door of a container or an apparatus. As shown in FIG. 9C, the base plate is fixed to the mounting surface. Attach the lever to the base plate with the shaft. Attach the hook to the lever with the shaft. Attach the catch plate to the lid. Attach the trigger to the base plate. The lever is provided with a slot that meshes with the trigger portion. Hook the catch plate and close the lid with the over center latch. When the lid is closed by the over center latch, the slot is engaged with the trigger portion and the over center latch does not open. The release operation can be performed by pulling the trigger portion in the direction opposite to the lid.

  The “hanging device” disclosed in Patent Document 6 is capable of easily and reliably tightening and locking. As shown in FIG. 9 (d), the latching device has a latching body and a receiver for latching it. The latch body has a lever body, a pedestal, and a latch. The lever main body has an operation end and a turning end opposite to the operation end formed in the longitudinal direction. The pedestal supports the swivel end with a shaft. The latch is supported between the operation end and the turning end. Locking means is provided at the operation end. The lock means includes an operation shaft portion, an engagement portion, and a spring. The operation shaft portion can reciprocate in the width direction of the lever body. The engaging portion is attached to the operation shaft portion, and when the lever main body is pivoted in a direction approaching the pedestal so as to be closed, the engaging portion is releasably hooked on the clasp. The spring urges the engaging portion to the outside in the width direction to be hooked on the clasp. When the latch is latched on the latch, the locking means is releasably latched on a latch provided at a position facing the operation end of the base. The release operation can be performed by pressing the lock means in the horizontal direction.

  However, the conventional snap lock has the following problems. In the configuration in which the latch that holds the open / close lever in the closed state is released with one push button, the snap lock is inadvertently opened when an accidental external force is applied to the push button. Further, in the configuration in which two latches are provided and released by the two push buttons on the pedestal side, the mechanism becomes complicated and the snap lock becomes thick, so that it becomes an obstacle when attached to a bag.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and make a latching snap lock thin and small so that it can be embedded in the side of a bag.

  In order to solve the above-mentioned problems, in the present invention, the pinch lock is fixed to the main body of the bag, a cradle fixed to the lid of the bag, and a link to the pedestal via a link. Two open / close levers connected to each other, a latch provided at an end of the open / close lever in the lid direction and engaged with a receiving rod, and two movable rods held by support shafts on both sides of the central portion of the open / close lever Latch lever, two fixed rods that are provided on the base and engage with the movable rod, a cylinder lock that is fixed at the center of the open / close lever between the two latch levers, and a lock for the cylinder lock that is provided on the base It was set as the structure which comprises the nail | claw receiving part engaged with a nail | claw.

  The pedestal is fixed to the bottom of the recess of the main body of the bag, and the cradle is fixed to the bottom of the recess of the lid of the bag, and the entire pinch lock is embedded in each recess. Installed in a state. Each latch lever is urged outward by a latch lever spring, and is arranged so that the engagement between each movable rod and each fixed rod is released by being pushed inward.

  By configuring as described above, the latching snap lock can be made thin and small and embedded in the side of the bag.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS.

FIG. 3 is a rear view of the double-tuck snap lock. FIG. 4 is an explanatory diagram of the operation of the double-tapping snap lock. FIG. 5 is a conceptual diagram of an embedded state of the double-tuck snap lock. FIG. 6 is a conceptual diagram of a modified example of the double-tuck snap lock.

  1 to 6, the opening / closing lever 1 is a lever that performs an operation of closing the double-tapping snap lock. The latch 2 is a tip portion of an opening / closing lever that meshes with the receiving rod. The latch lever 3 is a lever that is pushed with a finger when releasing the latch. The movable rod 4 is a hook that meshes with the fixed rod. The link 5 is a member that connects the base and the open / close lever. The receptacle 6 is a collar member fixed to the lid of the bag. The pedestal 7 is a member for attaching the double-tuck snap lock to the main body side of the bag. The fixed rod 8 is a rod member attached to the pedestal so as to mesh with the movable rod. The fixed and movable rods form a latch that holds the open / close lever to the base. The support shaft 9 is a rotation shaft for attaching the latch lever to the opening / closing lever. The cylinder lock 10 is a lock for locking the pinch lock. The spring 11 is a member that gives an elastic force in the opening direction of the opening / closing lever. The slide knob 12 is a knob that is slid when the latch is released.

  The function and operation of the dual knob snap lock of the present invention configured as described above will be described. First, the outline of the double-tapping snap lock will be described with reference to FIG. FIG. 1A shows a schematic diagram of the unlocked state. A receptacle 6 is fixed to the lid of the bag. The opening / closing lever 1 is connected to the pedestal via a link. The pedestal is fixed to the main body of the bag. A fixing rod 8 is provided on the pedestal. Since the pedestal and the link are the same as the conventional one, illustration is omitted. On the back side of the end of the opening / closing lever 1 on the lid side, there is a latch that is not visible, but is hung on the receiving rod 6. There are two latch levers 3 on both sides of the central portion of the opening / closing lever 1, which are attached to a supporting shaft that is not visible. Although not visible, the latch lever 3 has a movable rod. A cylinder lock 10 is provided between the two latch levers 3 at the center of the opening / closing lever 1.

  When the latch of the opening / closing lever 1 is engaged with the receiving rod 6, the intermediate state shown in FIG. When the open / close lever 1 is tilted in this state, the movable rod is pushed by the fixed rod 8, the latch lever 3 moves inward, the movable rod and the fixed rod 8 are engaged, and the open / close lever 1 is held in the closed state. If the cylinder lock 10 is locked in this state, the opening / closing lever 1 cannot be opened. When the cylinder lock 10 is opened with a key and the latch lever 3 is pressed from both sides, the movable rod is detached from the fixed rod 8 and the opening / closing lever 1 can be opened. The latch of the opening / closing lever 1 is removed from the receptacle 6 and the lid of the bag is opened.

  With reference to FIG. 2, the function of the double knob snap lock will be described. The locked state is shown in FIG. When the cylinder lock 10 is locked in the locked state, the lock claw of the cylinder lock 10 is engaged with the claw receiving portion provided on the pedestal 7 to enter the locked state, and the opening / closing lever 1 cannot be opened. When opening the lid of the bag, open the cylinder lock 10 with a key. The master key of the cylinder lock 10 can be a TSA key. When both the latch levers 3 are simultaneously pushed inward with the cylinder lock 10 unlocked, the latch lever 3 slightly rotates around the support shaft as shown in FIG. The movable rod 4 on the inner side of the distal end of the rod moves away from the fixed rod 8 and enters a non-latching state. In this state, the opening / closing lever 1 is moved and opened in the opening direction by the elastic force of the spring, and the latch can be removed from the receiving rod. Even if only one latch lever 3 is pushed, the movable rod 4 of the other latch lever 3 does not move away from the fixed rod 8. Therefore, even if the latch lever 3 is accidentally moved by an external force, the latch is released and the opening / closing lever 1 is opened. There is nothing.

  Next, the operation of the latch lever will be described with reference to FIG. In the locked state shown in FIG. 3A, the movable rod of the latch lever 3 is engaged with the fixed rod of the base. The latch lever 3 is swingably attached to the opening / closing cover 1 by a support shaft 9 and moves so as to rotate within a certain angular range. Although not shown, since the elastic force is applied to the outside by the spring for the latch lever, the movable rod is stably meshed with the fixed rod. By pressing the abdomen of both latch levers 3 with a finger, the movable rod is detached from the fixed rod, and the non-latching state shown in FIG.

  Next, the opening / closing operation of the opening / closing lever will be described with reference to FIG. In the unlocked state shown in FIG. 4A, the opening / closing lever 1 is pushed up in the direction away from the base 7 by the elasticity of the spring 11. Since it is connected to the pedestal 7 by the link 5, it can be moved up and down and forward and backward in a certain range. When locking, the latch 2 at the lid side end of the open / close lever 1 is hung on the receiving rod 6 to be in the intermediate state shown in FIG. In this state, when the opening / closing lever 1 is tilted toward the main body, the movable lever of the latch lever hits the fixed rod 8 of the pedestal 7 and the movable rod moves to the fixed rod 8 while the latch lever moves inward. Engage with each other to enter the locked state shown in FIG.

  At this time, the lower end of the cylinder lock 10 enters the hole of the base 7. When the cylinder lock 10 is closed with a key, although not shown in the drawing, the lock claw at the tip of the cylinder lock 10 turns to a position where it comes into contact with the claw receiving portion of the pedestal 7 and enters a locked state. In this locked state, the open / close lever 1 cannot be opened even if the latch is released by pushing the latch lever. When unlocking, operate in the reverse order. When the cylinder lock 10 is opened with a key and both latch levers are pressed simultaneously, the latch is released, and the open / close lever 1 is pushed up by the elasticity of the spring 11, resulting in the intermediate state shown in FIG. Further, when the latch 2 of the opening / closing lever 1 is removed from the receiving rod 6, the unlocked state shown in FIG. 4 (a) is obtained, so that the lid can be opened.

  Next, with reference to FIG. 5, the embedding state of the double-tapping snap lock will be described. Embed the pinch lock in both sides in the recess on the surface to which the lock of the bag is attached. A gap for inserting a finger for pressing the latch lever 3 is provided in the recess. Since there is no protrusion of the lock on the surface, even if a bag hits an object, no force is applied to the lock and the lid does not open. Even if an external force may be applied to the lock, it is unlikely that an accidental external force will be applied to both latch levers 3 at the same time, so the lid of the bag will not open carelessly.

  Next, with reference to FIG. 6, a modified example of the double-knob snap lock will be described. 6A to 6D are examples in which the latch lever is a slide knob. When the latch of the open / close lever 1 is hooked on the receiving lever and the open / close lever 1 is tilted, the movable rod 4 of the slide knob 12 hits the fixed rod 8 of the base as shown in FIG. The movable rod 4 meshes with the fixed rod 4 and the locked state shown in FIG. In the locked state, as shown in FIG. 6B, when both the slide knobs 12 are simultaneously slid in the cover side direction, the latch is released and the opening / closing lever 1 can be opened. As shown in FIG. 6 (d), the fixed rod 8 may be provided outside the opening / closing lever 1, and the movable rod 4 may be extended outside the tip of the opening / closing lever 1. As another modification, a cylinder lock 10 may be provided outside the opening / closing lever 1 as shown in FIG. The opening / closing lever 1 is fastened with the locking claw of the cylinder lock 10. Since the length becomes long but the width becomes narrow, it can be used when there is a margin in the length but the width is limited.

  As described above, in the embodiment of the present invention, the double-tapping snap lock is supported on both sides of the central portion of the open / close lever by hanging the open / close lever by hooking the open / close lever on the catch on the lid of the bag. Since the movable latches of the two latch levers attached on the shaft are engaged with the fixed rods provided on the pedestal, the closed state of the open / close lever is maintained, and the key is locked with the cylinder lock between the two latch levers. The latching snap lock can be made thin and small and can be embedded in the side of the bag.

  The double-tapping snap lock of the present invention is most suitable as a snap lock that closes the lid of a bag and locks it. It can also be applied to various doors.
