Description

  The present invention relates to a closing device for preventing an opening of a storage member such as furniture or the like from an opening door, a drawer or a sliding door during an earthquake.

  Conventional seismic closing devices are mainly intended to prevent the opening of storage doors such as furniture during earthquakes and prevent the fall of stored items. Japanese Patent Application Laid-Open No. 9-177712 discloses a structure in which an engagement body having a locking portion and a receiving member are engaged to prevent the door from being opened by the operation of the rolling body within the rolling body case. Many have been disclosed. In these configurations, an arrangement in which a main body member having a rolling element is attached to an inner upper surface of a frame body that is an installation body, and an engagement member is attached to an inner upper portion of a rotary door that is a moving body.

  Here, when the closing device is attached to the opening door as described above, it is important not to get in the way of storage and removal. Therefore, it is natural to make the whole compact, and in particular, it has been required to reduce the thickness direction. However, since it is used for a long time, the door may hang down after installation, or the engagement position of the main body member and the engagement member may be out of order due to warpage of the door, etc. Further, an allowable error at the installation stage is also necessary It is. As a result, it is indispensable to keep a wide engagement range, and accordingly, the size tends to increase, which tends to conflict with the above-described compacting.

  In recent years, not only opening doors but also drawers and sliding doors are required to be prevented from opening during an earthquake. In this case, the moving body corresponding to the door is a drawer or sliding door, and the body member of the closing device is mounted on the frame corresponding to the installation body, and the engaging member is mounted on the moving body. . Also, when installing a closing device on the drawer, it will be in the way of loading / unloading the stored items when protruding to the storage space side.Therefore, either at the back of the drawer or between the drawer rails on both sides and the frame side plate Or it is limited to the upper position of the side plate of the drawer, and it is assumed that the installation space is narrow.

In addition, many of the conventional closing devices have a mechanism in which the rolling element spontaneously returns to the release position when left for a few seconds after the engagement operation due to shaking is completed, or the moving body opens slightly after the engagement operation. It already has a mechanism that can be released from the closed state by a complete reclosing operation. However, an unexpected impact or sudden force may be applied at the time of closing, and this release operation may not work.In such a case, it has recently been possible to open the moving body without damaging the storage member itself. There are still few that have been required and have a mechanism that can forcibly release the closed state.
Japanese Patent Laid-Open No. 9-177412

  Therefore, it is immediately engaged when it detects an earthquake shake, and has a structure that can be released naturally by leaving it for several seconds after convergence. A closing device configured to be able to cope with a later shift in position is desired. Furthermore, even if the natural release operation does not work due to an unexpected impact, etc., and the situation where the closed state cannot be released occurs, the mobile object is forcibly released by a separate operation without destroying the storage member itself. A compulsory release means that can be largely opened is also required.

The present invention has been made to solve the above-described problems, and prevents the moving body such as a door and a drawer from being opened when the rolling element inserted into the main body case moves from the release position due to shaking, Added a mechanism that automatically guides the main body member and engagement member to the optimal position at the final stage of closing of the moving body, realizing a compact form that does not prevent the storage and removal of items, and locking by an unexpected phenomenon It is an object of the present invention to provide an earthquake closing device having a new configuration having a forced release means that can be opened even when it cannot be released from the state.

  In the present invention, the following technical means are provided to solve the above problems. First, a box-shaped main body case is provided, a locking projection is arranged on the upper surface inside the main body case, an elevating slope and a flat surface continuous to the uppermost part are arranged on the inner side, and the bottom surface of the main body case is lowered on the inner side. Leave it tilted. And a main body member is comprised in the state which inserted the spherical-shaped rolling element in the main body case. At this time, in a state where the rolling element is stopped at the lowest position of the inclined bottom surface which is the back side, it is set so that the vertex of the rolling element is slightly lower than the flat surface. And a main body member is mounted | worn with the installation body side of storage members, such as furniture. Further, the state where the rolling element stops at the lowest position of the inclined bottom surface is set as the release state, and the position of the rolling element is set as the release position.

  Next, an engaging claw is arranged upward at the tip of the engaging body, an angle restricting portion is provided at the opposite end so that the engaging body can be rotated only in a certain angle range in the vertical direction, and the shaft portion positioned therebetween is arranged. The engaging member is configured to be rotatably mounted on the mounting base. This engaging member is attached to a moving body such as a door or drawer of a storage member such as furniture. And both are arrange | positioned so that an engaging body may enter / exit in a main body case by opening / closing operation | movement of a moving body. Therefore, when the main body member and the engaging member are disengaged, the engaging claw is held at the reference angular position that is somewhat lower than the horizontal position, and the rolling element stops at the release position in the main body case. Yes. The engaging body is inserted into the main body case immediately before the moving body is completely closed by the closing operation. At this initial insertion stage, the engaging claw is disposed at the reference angular position and does not interfere with the locking projection. Then, the engaging body tip is brought into contact with the ascending / descending slope and the engaging claw is lifted, and when the moving body is completely closed, the engaging body lower surface tip is held on the flat surface.

  At this time, the left and right weight balance of the engagement body with the shaft portion as a boundary is formed so that the engagement claw side is much heavier. Then, in the normal operation of releasing the moving body, the front end of the engaging body is lowered downward along the ascending / descending slope due to the weight of the engaging body itself in the initial stage, so that the moving body escapes from the main body case as it is. The claw does not engage. In addition, it is better to provide an elastic piece with springiness so that it is always biased to the reference angle position. In the closed state, the engagement claw is slightly lifted against the elastic piece, and the reference angle position Therefore, it is possible to obtain an operation in which the engaging claw descends along the ascending / descending slope more reliably when released. As a result, the moving body opens and closes while repeating the swinging motion in which the front end of the engaging body moves up and down along the ascending / descending slope. Further, in the normal opening / closing operation of the moving body, the engaging body does not contact the rolling element. Further, in this closed state, the dimension between the lower surface of the engagement body and the inclined bottom surface is set to be slightly larger than the diameter of the rolling element at any position. That is, the inclination of the lower surface of the engaging body in the closed state may be set to be parallel to the inclination of the inclined bottom surface.

  Next, when an earthquake occurs in the closed state in which the engaging body is inserted into the main body case, the rolling element rolls within the main body case and moves out of the release position even with a small shake. When the shaking converges as it is, the rolling element naturally returns to the release position by the inclined bottom surface, and the normal opening / closing operation becomes possible. However, when a strong shaking occurs and the moving body opens and the engaging body tries to escape from the main body case, the rolling element is naturally out of the release position at this stage, so the lower surface of the engaging body rides on the apex of the rolling element. Thus, the engaging claw cannot move downward along the ascending / descending slope, and as a result, the engaging claw engages with the locking projection to prevent the moving body from being released. A state in which the engaging claw and the locking projection are engaged is defined as a locked state. When the shaking due to the earthquake is settled, the rolling element naturally returns to the release position by the inclined bottom surface, and the moving object can be opened again without any further operation.

  Also, even when an earthquake occurs when the moving body is opened, if the moving body is closed as it is, the engaging claw tip at the reference angle position lowered downward when the engaging body is inserted into the main body case. The operation of pushing the rolling element that is rolling in the main body case into the release position is obtained, and the engaging member can be inserted into the main body case and the moving body can be closed. Then, when the shaking continues in the completely closed state, an operation for preventing the subsequent opening of the moving body is obtained in the same manner as described above.

  Here, the operation of the engaging body by opening and closing the moving body is an operation of passing through the locking protrusion by swinging the neck up and down. In order to ensure, the vertical positional relationship between the main body member and the engaging member is very important. Therefore, the base material for the engagement member is divided into a support member for rotatably mounting the attachment member and the engagement body, and the position of the support member relative to the attachment member can be moved only in the vertical direction and is held at the moved position. Configure to be able to. And it is good to provide a guide surface in the up-and-down position of a support member, and the front side inner surface of a main body case. Then, the support member is guided and inserted along the guide surface of the main body case at the final closing stage of the movable body, and the vertical position of the engaging body with respect to the main body case can be automatically set to the reference position. That is, the main body member and the engaging member are attached to the installation body and the moving body, and when the moving body is first completely closed, the support member on which the engaging body is mounted is guided up and down to move to the reference position, and Since it is held at this position, both will always enter and exit at the reference position from the next opening / closing operation. Therefore, the contact between the guide surfaces of the main body case and the support member for this guidance is only the first time. Furthermore, even if the position of the moving body becomes out of order for a long period of use, it is automatically re-guided, and operation at the reference position is always possible. Further, the vertical movement operation by this automatic guidance is not limited to the engagement member side, and may be arranged on the main body member side.

  In addition, when a very strong shaking occurs and the weight of the moving body itself is heavy, such as a drawer, a sudden opening operation is performed, and a very large force is applied in the direction of further releasing in the locked state. Therefore, if the locking projection of the locking projection and the engaging claw is applied with a force in a locked state, an inclined surface is provided so that both are further engaged, or the fitting convex portion and the fitting concave portion are provided separately on both, If both are fitted, the moving body can be more reliably prevented from opening.

  Next, a connection member is further provided between the attachment member and the support member, and the attachment member and the support member are connected via the connection member. And it is set so that it can move in a state having a certain holding force only in the vertical direction. Further, a guide surface is provided on the support member, and the support member is set to move automatically in the vertical direction with respect to the connecting member. Furthermore, the mounting member and the connecting member are held with a force larger than that required for the movement operation by automatic guidance. This holding force is set to such an extent that the connecting member can be removed from the support member and the attachment member when a forced separating means is used. And if it arrange | positions so that a connection member can be removed from the clearance gap slightly opened in the closed state, a support member and an attachment member can be isolate | separated, and it becomes possible to forcibly open a mobile body. In other words, even in an emergency when the engaging claw cannot be released while it is locked to the locking projection due to an unexpected situation, and the moving body cannot be released, the moving body is slightly opened to the closed position, and the narrow object is removed from the gap. It is possible to cancel the emergency by inserting and removing the connecting member. Further, the forcible releasing means by the connecting member may be arranged not only on the engaging member side but on the main body member side.

  When opening and closing the moving body, use the action of the engaging body to pass through the locking protrusion by swinging the neck up and down, and restrict the downward movement of the engaging claw when released by the movement of the rolling element by shaking Since the engaging claw is engaged with the locking projection to prevent the moving body from being released, the rolling element is always in a free state, and the rolling operation starts immediately even with a small shake. When the rolling element rolls slightly from the release position, it is possible to immediately prevent the moving body from being released, and a highly sensitive closing operation can be obtained.

  When the shaking due to the earthquake is settled, the rolling element naturally returns to the release position by the inclined bottom surface, and the moving body can be released again by simply waiting for a few seconds. In addition, when the shaking converges in a closed state in which the moving body is slightly opened, it may be assumed that the engaging body remains on the top of the rolling body. When fully closed to the closed position, the contact between the rolling element and the engagement body is avoided, and the opening operation can be performed again by simply waiting for a few seconds.

  By forming the angle restricting member at the end of the engaging body with an elastic piece, the engaging body is held at the reference angular position, and in the closed state, the elastic piece is biased by the amount moved upward. Thus, a force to slightly return to the downward direction, which is the reference angle position, is applied, and an operation of reliably lowering the neck along the ascending / descending slope is obtained when the engaging member enters and exits. As a result, even when the moving body is suddenly released, it is possible to prevent a malfunction in which the engaging claw and the engaging projection engage with each other by moving in the lateral direction faster than the engaging claw lowers.

  Even if an earthquake occurs when the moving body is open, if the moving body is closed as it is, the tip of the engaging claw at the reference angle position lowered downward is inserted in the main body case when the engaging body is inserted into the main body case. The operation of pushing the rolling element that is rolling into the release position is obtained, and the engaging body can be inserted into the main body case and the moving body can be closed. And after completely closing, even if it is in the state where the vibration has continued, the operation | movement which prevents the opening of a moving body is obtained similarly.

  When the mounting base is divided into a mounting member and a support member, the support member with the engagement body can be moved only in the vertical direction with respect to the mounting member and can be held at the moved position. The support member is automatically guided to the reference position and inserted along the guide surface of the main body case and the guide surface of the support member at the final closing stage of the body, and the engagement operation at the proper vertical position can be surely obtained. it can. In addition, even if the position of the moving body becomes out of order during long-term use, it is automatically re-guided, and operation at the reference position is always possible.

  In addition, if a connecting member is further provided between the mounting member and the supporting member of the engaging member, the engaging claw cannot be removed while engaging the locking projection due to an unexpected situation, and the moving body cannot be released. Even at the time, the supporting member and the mounting member can be separated by inserting a thin object from the gap between the moving body and the installation body in the slightly opened closed state and forcibly removing the connecting member, and the moving body is closed. Can be forcibly released.

  It is conceivable that the position of the moving body with respect to the installation body may change after the closing device is installed, or the engagement position of the main body member and the engagement member may be out of order due to warpage of the installation body or the moving body itself, Since tolerances at the stage of installation are also necessary, it is necessary to keep a wide range of engagement, and the only effective means to cope with this is to increase the overall size. On the other hand, in the present invention, the automatic guide means for forcibly guiding to the reference position is added, so that the minimum compact size can be achieved.

  It is a simple configuration with only a small number of parts consisting of a main body member consisting of a main body case and rolling elements, and an engaging member consisting of an engaging body and a mounting base material. Other than the rolling elements, it can be manufactured as a resin molded product. It can be produced at low cost.

  Embodiments of the seismic closing device of the present invention will be described below with reference to the drawings. The closing device of the present invention can be applied to opening and closing portions of various storage members composed of an installation body and a moving body. In the embodiment, the drawer 34 is opened and closed forward and backward with respect to the frame body 36, and the frame body. A configuration in which the main body member a and the engaging member b are separately mounted in the configuration in which the door 35 rotating with a hinge etc. opens and closes with respect to 36 and the configuration of the sliding door composed of the frame body 36 and the door body 37. I will explain. FIGS. 1-18 has shown the state which mounted | wore the drawer 34 with the closing device of this invention as 1st embodiment. FIG. 1 is a perspective view of a state in which the main body member a of the closing device is mounted on a frame 36 corresponding to an installation body, the engaging member b is mounted on a drawer 34 corresponding to a moving body, and the drawer 34 is opened. FIG. 2 is a perspective view of a closing device including a main body member a and an engaging member b in the first embodiment. FIG. 3 is a side sectional view of the drawer 34 with the drawer 34 closed. The position at which the main body member a and the engaging member b are mounted is not particularly limited, but the position that does not interfere with the loading / unloading of the stored items is either the upper position at both ends of the drawer 34 shown in FIG. In the first embodiment, as shown in FIG. 1, the engaging member b is disposed at the upper position of the front inner surface of both ends of the drawer front plate 32, and the main body member a is disposed at both front ends of the frame side plate 33. This will be described in the mounted arrangement.

  As shown in FIG. 2, the main body member a is formed of a box-shaped main body case 1 having a mounting surface 7 and a rolling element 8 which is a metal sphere, and the engaging member b has an engaging claw 10. The engaging body 9 and the attachment base 12 are comprised. 4 is a side view of the main body case 1, and FIG. 5 is a cross-sectional view taken along line A-A 'in FIG. As shown in FIG. 4, an opening 5 is provided on the front surface of the main body case 1, an inclined bottom surface 4 having a small inclination is provided at the inner bottom position, and an ascending / descending slope 2 and a flat surface 3 continuous therewith are provided at the inner position. Prepare. The upper back side of the flat surface 3 is left open. Further, a locking projection 6 is provided at the internal ceiling position of the main body case 1. At this time, as shown in FIG. 5, the ascending / descending slope 2 and the flat surface 3 are disposed on both side ends, and the central portion is stolen. Further, the inclined bottom surface 4 is inclined so as to be lowered from the opening portion 5 side toward the flat surface 3, and is set so that the innermost position of the main body case 1 is lowest. Then, the rolling element 8 is inserted into the main body case 1.

  Then, as shown in FIG. 5, the rolling element 8 is stopped and held at the deepest position, which is the lowest position on the inclined bottom surface 4, while riding on the inclined bottom surface 4. Is the release position. Therefore, when a shake due to an earthquake occurs, the rolling element 8 rolls on the inclined bottom surface 4 and when the shake is converged, the rolling element 8 naturally returns to the release position again. Further, as shown in FIG. 5, the corners of the ascending / descending slope 2 may be cut obliquely so that the rolling elements 8 can easily return to the release position. Next, the relationship between the height of the flat surface 3 and the diameter of the rolling element 8 is set so that the apex of the rolling element 8 at the release position is slightly lower than the flat surface 3 as shown in FIG. 2 so that the rolling element 8 does not come out to the very front side. Further, a locking projection 6 is arranged at an upper ceiling position slightly ahead of the ascending / descending slope 2. Further, it is preferable to separately provide means such as providing a wall portion at a lower position on the front surface of the main body case 1 so that the rolling elements 8 do not come out of the main body case 1.

  FIG. 6 is a side view of the engaging member b in the first embodiment, and FIG. 7 is a top view. As shown in FIG. 6, the engagement member b includes an attachment base 12 and an engagement body 9, and the attachment base 12 rotatably holds the attachment surface 7 and the engagement body 9 for attachment to the drawer front plate 32. The support portion 13 is arranged in a state of protruding in a U-shape on the left and right sides of the mounting surface 7, and a shaft insertion long hole 14 in the vertical direction is further provided. The engaging body 9 has a flat plate shape and is provided with an engaging claw 10 facing upward at the tip, and a tapered surface 16 is also provided on the lower surface of the tip. Further, shaft portions 15 are arranged on both side surfaces on the opposite side, and the shaft portions 15 are fitted into the shaft insertion long holes 14 of the support portion 13 so that the head can be swung only within a certain angle range in the vertical direction. .

  The range of this swinging motion and the angular position at which it is stopped and held in a natural state are important. Therefore, as shown in FIG. 6, an angle restricting portion 17 may be provided between the shaft portion 15 and the back surface of the support portion 13. Here, if the weight of the engaging claw 10 side and the angle restricting portion 17 side of the engaging body 9 with the shaft portion 15 as a boundary is set so that the engaging claw 10 side is much heavier, the engaging body 9 will be self-weighted. Thus, the position is stopped and held at the most drooping position in FIG. 6A, and this state is set as a reference angular position. Then, it becomes possible to rotate from the reference angle position to the position shown in FIG. 6 (b) by swinging, and the engaging body moves slightly upward from the horizontal position at the angle shown in FIG. 6 (b). It is good to set as much as possible.

  FIG. 8 sequentially shows the operation when the main body member a is attached to the frame body side plate 33 and the engaging member b is attached to the drawer front plate 32 and the drawer 34 is opened and closed during normal use as shown in FIG. It is side surface sectional drawing. Further, in order to make the figure easy to understand, in FIG. 8, the front drawer plate 32 and the frame side plate 33 are omitted, and only the main body member a and the engaging member b are described. FIG. 8 (a) shows a stage immediately before the drawer 34 is closed to some extent from the state of being largely opened and completely closed, and the front end of the engaging body 9 is already inserted from the opening portion 5 of the main body case 1. Of course, since there is no shaking such as an earthquake, the rolling element 8 is stopped at the release position.

  In the state of FIG. 8A, the tip end portion of the engaging body 9 having the engaging claw 10 is lowered by its own weight and held at the reference angular position. It is set so that the upper end is positioned slightly below the lower surface of the locking projection 6. When the drawer 34 is further closed, the tapered surface 16 at the lower end of the engaging body 9 comes into contact with the ascending / descending slope 2 as shown in FIG. At this stage, the engaging claw 10 has already been inserted deeper than the locking projection 6, and thereafter the engaging body 9 is lifted along the ascending / descending slope 2 as shown in FIG. The engaging member lower surface 11 in FIG. 8D moves to a position on the flat surface 3. FIG. 8D shows the same state as FIG. 3 in which the drawer 34 is completely closed.

  The angle of the lower surface 11 of the engaging body in the closed state shown in FIG. 8D is important and should be set to be parallel to the inclination of the inclined bottom surface 4. The reason why the long shaft insertion hole 14 is elongated in the vertical direction is that the surface of the engagement body 9 is not always horizontal when the attachment base 12 of the engagement member b is fixed to the front drawer plate 32. Even when the engaging body 9 is inserted obliquely due to an error in installation, the inclined bottom surface 4 and the engaging body lower surface 11 can be parallel while the rotating shaft of one side of the engaging body 9 is in a floating state. Even if an attachment error or the like occurs, they are always provided in parallel.

  Next, when the drawer 34 is opened from the closed state of FIG. 8D, the engaging body 9 lowers the tip portion by its own weight from the stage of FIG. 8C, so that the overall operation is as shown in FIGS. Therefore, the opening / closing operation of the drawer 34 during normal use can be performed without any problem. In this normal opening / closing operation, the engagement body 9 and the rolling element 8 do not come into contact with each other, and the rolling element 8 always maintains the state stopped at the release position. In addition, the engaging member b and the main body member a are in contact with only the tapered surface 16 of the engaging body 9 and the ascending / descending slope 2 during the opening / closing operation. It is assumed that there are relatively few. In order to further reduce the contact sound, it is preferable to attach a soft resin, rubber or the like to either contact surface.

  FIG. 9 is a side cross-sectional view sequentially illustrating a state in which shaking due to an earthquake occurs in a closed state. In the state of FIG. 9A, the inclined bottom surface 4 and the engagement body lower surface 11 are parallel as described above, and in this state, the rolling element 8 contacts the engagement body lower surface 11 regardless of the position. Therefore, the rolling element 8 starts to freely roll in the main body case 1 as shown in FIG. When the greater shaking occurs, the drawer 34 itself is opened. Then, the engaging body 9 tends to come off from the main body case 1, but as shown in FIG. 9 (b), since the rolling element 8 rolls away from the release position, the lower surface 11 of the engaging body is in contact with the rolling element 8. It will be in the state which got on the top, and the engaging claw 10 will not be the operation | movement which goes down along the raising / lowering slope 2. FIG. Then, when the drawer 34 is slightly opened, the engaging claw 10 is engaged with the locking projection 6 at the stage shown in FIG. 9C, and in this state, the opening of the drawer 34 can be prevented. . The important point here is that it must be set so that the lowering of the engaging claw 10 is surely prevented in any position other than the release position, even if the rolling element 8 is located. It is necessary that the continuous portion of the ascending / descending slope 2 and the flat surface 3 be close to the apex position of the rolling element 8 so that a reliable closing operation can be obtained even when the moving body 8 is moved from the release position.

  FIG. 10 is a side sectional view showing a closed state at the time of an earthquake, showing a state in which the rolling element 8 is rolling in the main body case 1, and a position that has moved only slightly closest to the release position. However, it can be seen that the engaging body 9 is not lowered and the engaging claw 10 and the locking projection 6 are engaged and securely closed. Further, in order to make the engagement of the engaging claw 10 and the locking projection 6 more reliable, it is preferable to provide an inclination on the locking surface 18 of the both. If it adds, the allowance will become larger and it will become possible to support a load with the engaging claw 10 whole.

  Further, when the swing is very large and the weight of the drawer 34 itself is heavy, a stronger opening force or impact is applied to the locking surface 18 from the state of FIG. 10, and the rolling element 8 is applied to the front portion of the main body case 1. In such a situation, it is considered that the warping and twisting of the engaging body 9 occurs, and a more reliable locking operation between the engaging claw 10 and the locking protrusion 6 is desired. Therefore, as shown in FIG. 11, the fitting projections 19 and the fitting recesses 20 are provided separately on the locking surfaces 18 of the engaging claws 10 and the locking projections 6, and the fitting projections 19 and the fitting recesses are locked in the locked state. If the 20 is formed so as to fit each other, the opening operation of the drawer 34 can be more reliably prevented. The fitting projections 19 and the fitting recesses 20 may have a single groove shape as shown in FIG. 11, but other methods may include a plurality of fine irregularities or a knurled shape. It is not particularly limited.

  However, it is conceivable that the rolling element 8 is positioned just at the release position during the rolling at the time of an earthquake, but when the drawer 34 moves greatly in the opening direction at that time, it opens. As a probability, when the drawer 34 is opened, the rolling element 8 is also applied with a force in the same direction, and it is relatively unlikely that the rolling element 8 and the drawer 34 move in the opposite directions at the same time. It can be assumed that the probability is very low. However, if the motion is such that the rolling element 8 jumps irregularly in the main body case 1 due to excessive shaking, it cannot be said that the above phenomenon never occurs. Therefore, as a means for reducing the probability of opening, for example, a small unevenness is provided on the inclined bottom surface 4 so that the rolling elements 8 easily come out of the released position on the inclined bottom surface 4 and are difficult to return to the released position at the same time. It is good to provide means such as. Further, as shown in FIG. 12, when two or more rolling elements 8 are arranged in the main body case 1 and are rolled in a state of being divided into sections, the probability that the plurality of rolling elements 8 are simultaneously at the release positions is further increased. It is thought to go down.

  Further, when the swing is relatively small and the swing is converged without opening the drawer 34 itself only by rolling the rolling element 8, the rolling element 8 naturally returns to the release position as it is by the inclined bottom surface 4. After waiting, it can be opened and closed normally. In addition, when the shaking converges in a state where the shaking is large and the drawer 34 is closed in an attempt to open, it is conceivable that the engaging body 9 remains on the rolling element 8. In that case, the drawer 34 should be completely closed once. In the closed state of FIG. 8D, the apex of the rolling element 8 and the engaging body lower surface 11 are surely separated from each other, so that the rolling element 8 naturally returns to the release position. become. Moreover, in the structure which provided the fitting convex part 19 and the fitting recessed part 20 in the latching surface 18 shown in FIG. 11, both will remain hooked in the latching state, and even if only the rolling element 8 returns to a releasing position. Since it is not released, an operation to close the drawer 34 once is similarly required.

  FIG. 13 shows a case where an earthquake has occurred with the drawer 34 opened. In the opened state, the tip of the engagement body 9 is at the lowered reference angle position. Even if the inside is rolling, if the drawer 34 is closed as it is, the tip of the engaging body 9 or the tapered surface 16 comes into contact with the rolling body 8 as shown in FIG. 13A, and as shown in FIG. The operation is to push the rolling element 8 back to the release position, and as a result, the drawer 34 can be closed as it is. Even when the shaking continues after that, the same closing operation as described above can be obtained from the stage of complete closing.

  As described above, in the normal opening / closing operation, the engaging claw 10 engages with the locking protrusion 6 only when the engaging body 9 enters and exits the main body case 1 while repeating the swinging motion. Thus, the drawer 34 can be closed. In the above description, the vertical movement of the engagement body 9 has been used as a drop operation due to its own weight with the shaft portion 15 as a fulcrum. However, if the drawer 34 is opened at a very high speed when the drawer 34 is opened, the movement of the engaging claw 10 in the lateral direction becomes faster than the movement of the engaging claw 10 along the ascending / descending slope 2, and There is a possibility that a malfunction occurs in which the pawl 10 is engaged. In this malfunction, if the drawer 34 is closed again and the drawer 34 is opened at a normal speed, there is no particular problem and it can be opened. This is not a fatal defect, but it is better to take measures to avoid the malfunction itself.

  Therefore, as shown in FIG. 14, the angle restricting portion 17 of the engagement body 9 may be formed by two upper and lower elastic pieces 21. FIG. 15 is an enlarged perspective view of the elastic piece 21 portion when the engaging body 9 is manufactured by a resin molded product. The thin elastic piece 21 is extended in the vertical direction, and the support portion 13 is shown in FIG. It arrange | positions so that it may contact the inner surface. At this time, it is important to set so that the engaging body 9 is held at the reference angular position by the upper and lower elastic pieces 21. The force by the elastic piece 21 is set to be relatively small, and when the rotary operation is performed about the shaft portion 15 in the vertical direction from the state shown in FIG. Therefore, a force to always return to the reference angular position is applied.

  As a result, the engaging claw 10 at the final stage of closing the drawer 34 is lifted along the ascending / descending slope 2 and the elastic piece 21 is pressed by the moving angle. There is a force to return in the direction. Accordingly, when opened, a force is applied in the direction of lowering the engaging claw 10 along the ascending / descending slope 2 by the upper elastic piece 21, and the engaging claw 10 and the locking projection 6 are engaged even when the drawer 34 is opened very quickly. It is possible to prevent malfunctions.

  However, when the angle restricting portion 17 is formed by the elastic piece 21 as shown in FIG. 16, the rotatable range around the shaft portion 15 of the engaging body 9 becomes unclear, and the elastic piece 21 has elasticity. Since there is a limit to the rotation angle in the case, it is necessary to take another means for angle regulation. As the means, an angle regulating piece 22 may be provided on the inner surface of the U-shaped support portion 13 as shown in FIG. Then, as shown in FIG. 18, when the engaging body 9 rotates by a certain angle, the lower surface of the end portion on the shaft portion 15 side of the engaging body 9 abuts on the angle regulating piece 22, and the engaging body 9 rotates in a certain angle range. Can be limited. FIG. 18A shows a state where the engaging body 9 is lowered to the lowest side within the range restricted by the angle restricting piece 22, and FIG. 18B shows a state where the engaging body 9 is lifted to the uppermost side. It is set so that the urging force of the elastic piece 21 can be maintained in the operation.

  Further, as shown in FIG. 1, when the engaging member b is mounted at the upper position of the side plate of the drawer 34, there is no hindrance in the normal operation of taking in and out the stored items in the drawer 34. However, in this arrangement, the engaging body 9 protrudes from the support portion 13 and is in a floating state, and it is fully possible that the stored item is dropped or collided at the position of the engaging claw 10 at some time. The joint member b should not be damaged. In this case as well, it is effective to allow the engaging body 9 to rotate downward within a range having elasticity, and the rotatable range is the engaging claw at the lowermost side in FIG. If the lower surface of 10 is set to a position where it is on the upper surface of the side plate of the drawer 34, it is possible to prevent damage to the engaging body 9 when a large load is applied from above.

  In the closing device of the present invention, the vertical position of the engaging member b with respect to the main body member a is very important. When the vertical position is greatly deviated, the engaging body lower surface 11 and the inclined bottom surface 4 are not parallel in the closed state, It is conceivable that the operation of the rolling element 8 is hindered or the engagement condition between the engagement claw 10 and the locking projection 6 is changed, so that it does not operate properly. Therefore, in the configuration of the first embodiment, the support portion 13 is set so as to be inserted into the inner surface of the opening portion 5 of the main body case 1 without a large margin, and the mounting holes of the main body case 1 or the mounting base material 12 are set vertically. It must be lengthened and adjusted so that the vertical positions of the main body member a and the engaging member b are appropriate at the time of construction.

However, this adjustment work is laborious and the closed state is not visible from the outside. Therefore, a configuration that does not require adjustment is desired. As the means,
A guide surface 23 is provided at the upper and lower inner surface positions of the opening portion 5 of the main body case 1 and the upper and lower positions inserted into the main body case 1 of the support portion 13, and either one of them is configured to be slidable only in the vertical direction. In the final stage of closing, it is preferable to provide automatic guide means for moving the positions of the two to the optimum vertical position by the guide surface 23 of the main body case 1 and the guide surface 23 of the support portion 13. In addition, when this sliding movement is provided, there is provided a vertical position holding means that stops at that position without sliding down with a certain friction applied to the sliding surface. It can be held as it is, which is considered more effective.

  In implementing this automatic guiding means, it is simple to separate either the main body case 1 or the mounting base 12 into two parts and slide one side up and down on the separated surface. The side to be separated here may be either, but when attaching to the drawer 34 in the first embodiment, the attachment surface 7 and the support portion 13 of the attachment base material 12 are separated and the attachment member 24 and the support member 25 are separated. It is preferable that the support member 25 mounted with the engaging body 9 is moved up and down with respect to the attachment member 24.

  An example of an embodiment having an automatic guide means obtained by dividing the mounting base 12 into a support member 25 and a mounting member 24 will be described with reference to FIGS. 19 to 24 as a second embodiment. Therefore, in the second embodiment, the main body member a may be exactly the same as in the first embodiment. First, a front view of the support member 25 is shown in FIG. 19, and a front view of the mounting member 24 is shown in FIG. As shown in FIG. 20, a rectangular lump portion 26 having a mounting hole for the drawer front plate 32 is provided in the central portion of the mounting member 24, and its periphery is stolen. Then, as shown in FIG. 19, a wide-shaped square hole 27 is provided in the vertical direction so that the lump portion 26 can be barely fitted into the support member 25 in the horizontal direction. Then, as shown in FIG. 21, the support member 25 can be moved within the vertical range of the square hole 27 only in the vertical direction along the lump portion 26 in a state where both are assembled.

  FIG. 22 is a side view showing this state of vertical movement. The support member 25 is attached to the mounting member 24 fixed to the drawer front plate 32, and FIG. 22 (a) and FIG. It can be moved up and down as in (c). In FIG. 21 and FIG. 22, the engagement body 9 is omitted, but it is assumed that the engagement body 9 is actually rotatably mounted on the support member 25 as in the first embodiment. Further, as shown in FIG. 19, elastic portions 28 are provided on both side surfaces of the support member 25, and when the elastic portions 28 are always pressed against the mounting member 24 and compressed and moved up and down, The stop position of the support member 25 after movement can be held as it is by the tension and frictional force of the elastic portion 28. Further, as shown in FIG. 22, guide surfaces 23 are provided at two upper and lower positions of the U-shaped tip to which the engaging body 9 of the support member 25 is attached, and similarly at the upper and lower positions of the opening portion 5 of the main body case 1. Two guide surfaces 23 are provided.

  Next, in the configuration of the second embodiment, FIG. 23 shows an automatic guide operation when the engaging member b is attached to the main body member a while being displaced upward from the reference position. The automatic guidance operation will be described with reference to FIG. FIG. 23A shows a state immediately before the drawer 34 is completely closed. When the drawer 34 is further closed, the engaging claw 10 first comes into contact with the front surface of the locking projection 6 as shown in FIG. Then, the support member 25 and the guide surfaces 23 on the upper side of the opening portion 5 come into contact with each other as shown in FIG. Can be moved downward. If the dimension between the upper portions of the guide surfaces 23 of the support member 25 is set to be slightly smaller than the dimension between the inner surfaces of the opening portion 5 of the main body case 1, it will be relevant at the fully closed stage of FIG. The support member 25 including the united body 9 surely moves to an appropriate position.

  FIG. 24 (a) shows a state immediately before completely closing with the mounting shifted downward. Similarly, as shown in FIG. 24 (b), the lower guide surface 23 and the opening portion 5 of the support member 25 are shown. The lower guide surface 23 comes into contact, and the support member 25 shown in FIG. 24 (c) is lifted upward, so that it can be guided to an appropriate position shown in FIG. 24 (d). In addition, the position holding means after the guide can assemble the drawer 34 to the frame 36 and guide it to an appropriate position in the vertical direction when the drawer 34 is first completely closed, so that the position can be held. In the opening / closing operation of the drawer 34 from the next time, no contact noise or impact of the guide surfaces 23 for guidance is generated. Furthermore, even if the position of the drawer 34 is misaligned during a long-term use, it is automatically guided again by the closing operation, and an adjustment operation as a separate process is not necessary and the optimum engagement condition is always maintained. It becomes possible. There are many other automatic guidance means that can move in the vertical direction and can maintain the position, and any configuration may be used.

  Also, some sudden cause (a, sticky material adheres and the rolling element 8 does not roll. B) The mounting screw is loosened and the body case 1 is tilted so that the rolling element 8 does not return to the release position. The engaging claw 10 and the locking projection 6 are greatly damaged in the case 1. The storage member itself is tilted due to the earthquake.) The engagement between the locking projection 6 and the engaging claw 10 is released. It can be considered that the drawer 34 is not opened and the drawer 34 cannot be opened. Therefore, in such a case, it has recently been required that the drawer 34 can be forcibly opened without damaging the storage member itself. Next, a configuration that enables this forcible release is illustrated as a third embodiment. 25 to FIG.

  This forcible release means can also be achieved by various methods, but the important point is that the release means must be able to be implemented from a slight gap where the drawer 34 can be opened in the locked state. Therefore, either the main body member a or the engagement member b is attached to the movable body or the installation body via the detachable coupling member 29, and is connected from the gap between the movable body and the installation body that can be released in the locked state. Means for completely separating the members 29 by removing the member 29 is simple. The connecting member 29 may be disposed at any position, but when the closing device of the present invention is attached to the drawer 34, the engaging member b is easy to operate from a slight gap in the closed state as shown in FIG. If the connecting member 29 is further arranged in the vicinity of the attachment base material 12, the condition on the release operation surface is good.

  Accordingly, in the third embodiment, the body member a may be exactly the same as that in the first embodiment, and the attachment base 12 of the engagement member b is divided into the attachment member 24 and the support member 25 as in the second embodiment, and A configuration in which an H-shaped connecting member 29 is provided between them to connect the two is suitable. 25 is a top view of the engaging member b in the third embodiment, FIG. 26 is a perspective view of the connecting member 29, and FIG. 27 is a side view of the engaging member b. As shown in FIG. 25, a concave groove is provided in the vertical direction of the support member 25 and the mounting member 24 to which the engaging body 9 is attached, and half of the H-shaped coupling member 29 is inserted into the concave groove to connect the two. In addition, the connecting member 29 is configured to be slidable in the vertical direction in the concave groove. Further, similarly to the second embodiment, an elastic pressing force or friction is provided between the connecting member 29 and the supporting member 25 or between the connecting member 29 and the mounting member 24 so that the position of the supporting member 25 after the movement can be maintained. Keep it. If the movement of the mounting member 24 and the connecting member 29 is increased and the movement of the supporting member 25 and the connecting member 29 is lightened, only the supporting member 25 moves up and down in the guiding operation when the drawer 34 is closed. Will be guided.

  FIG. 28 is a side sectional view of the third embodiment, showing a state in which the main body member a and the engaging member b are engaged and closed. In the case shown in FIG. 29 that cannot be released in this state (for example, the mounting screw is loosened and an unexpected force is applied, the main body member a is greatly inclined and the inclined bottom surface 4 is lowered forward). As a matter of course, since the rolling element 8 does not return to the release position, the drawer 34 cannot be opened largely. In this state in the first embodiment and the second embodiment, even if it is forcibly released, the gap between the drawer 34 and the frame body in the locked state is very small as shown in FIG. 29, and the mounting screw is removed. In addition, a large-scale work for disassembling the drawer 34 and the frame 36 itself is required.

  However, with the configuration of the third embodiment, as shown in FIG. 30, a screwdriver or one with a narrow tip can be inserted from the upper gap in the closed state, and the connecting member 29 can be pushed down to be pulled out. By separating the member 25 and the mounting member 24, the locked state is released and the drawer 34 can be opened largely. Furthermore, after eliminating the cause of the malfunction, the connecting member 29 is again inserted into the concave groove to connect the support member 25 and the mounting member 24 and can be used again. In addition, the means for forcibly releasing the connection member 29 by removing the connection member 29 from the gap in the closed state is not limited to the above-described configuration, and may be a configuration in which the connection member 29 is pulled out in the lateral direction. In addition, it is possible to have a configuration in which the connecting member 29 is integrated with a thin string-like member, an operation member is attached to the end of the string, and the connecting member is removed by pulling out the operation member. There is no need for tools such as drivers in this case. In addition to these configurations, any other means may be used.

  In the above description, the embodiment has been described in which the closing device of the present invention is attached to the drawer 34 that is pushed and pulled back and forth to open and close, but the present invention can be applied to other storage members with the same configuration. FIG. 31 is a perspective view showing a state in which the closing device of the present invention is mounted on a hinged door that opens and closes around a shaft center such as a hinge as a fourth embodiment, and the main body member a is an installation body. The frame 36 is mounted on the upper inner surface, and the engaging member b is mounted on the upper portion of the door 35 as a moving body, and the engaging body 9 is simply inserted into the main body case 1 along the rotation path. It can be used as it is. In addition, the automatic guide means and the forced release means are naturally effective when mounted on the hinged door, and in the forced release means, the gap position in the closed state is the same as that when the drawer 34 is mounted. The position may be on the engaging member b side. However, in the case of a hinged door, it is necessary to be able to cope with both a low position installed on the floor and a high position such as a hanging cupboard, so that the connecting member 29 can be removed from both the upper and lower directions or from the gap on the door side. It must be pulled out in the horizontal direction.

  Moreover, the closing device of the present invention can be attached to a storage sliding door such as furniture, and a fifth embodiment will be described with reference to FIGS. FIG. 32 is a perspective view showing a state where the sliding member is mounted on a sliding door as a storage member. The main body member a is mounted on the upper inner surface on the door side of the frame 36 as an installation body, and the engaging member b is a moving body. It becomes the arrangement | positioning with which the inner side upper side of the door 37 is mounted | worn. In this case, the door body 37 is linearly moved in the same manner as the drawer 34 and can be used as it is. Although only one half of the sliding door is shown in FIG. 32, when the sliding door is normally used as a storage member, the sliding door is the mainstream, and the two door bodies 37 can be opened in both directions. FIG. 33 is a top plan view of a state in which the door is attached to a pulling door having two door bodies 37, FIG. 33 (a) shows a state in which both door bodies 37 are closed, and FIG. 33 (b) shows a front side. FIG. 33 (c) shows a state in which the door 37 on the back side is opened.

  Here, as a disposition of the closing device, it is preferable to attach to the upper part of the door tips side of both door bodies 37 as shown in FIG. Further, in recent doors to prevent misfitting, as shown in FIG. 33 (b), the door bottom side of the door 37 on the front side is not completely in contact with the vertical frame. As shown in (c), when the rear door 37 is opened, it can be opened only to the extent of the digging pull 31. Therefore, in many cases, a stopper, which is a separate component, is usually attached to the end of the rail and stops before the door 37 is completely opened. However, as shown in FIG. 33, in the configuration in which the closing device of the present invention is mounted, the door bottom surfaces of the door bodies 37 can be received on the back surface of the engaging member b, and soft materials such as rubber as shown in FIG. By attaching the buffer material 30 of the system, it becomes possible to also serve as the above-mentioned stopper.

  Moreover, in the case of a sliding door, it will be in a closed state as shown in FIG. 34 where a slight gap is opened on the door end side, and in the configuration in which the connecting member 29 is arranged on the engaging member b as in the third embodiment, the connecting member 29 is provided. The position becomes the back side of the door body 37, and a problem occurs in operability in the forced release. Therefore, as shown in FIG. 34, the main body member a may be divided into two parts, the main body case 1 and the mounting member 24, and a connecting member 29 may be disposed therebetween. And the direction which removes the connection member 29 is easy if it implements by the operation | movement pushed to the front-back direction. Therefore, the engaging member b in the fifth embodiment does not need the connecting member 29, and only the automatic guiding means is provided as shown in FIG.

  In addition, the closing device of the present invention can be applied to not only the storage member described in the above embodiment, but also other storage members such as folding doors and flip-up doors, although not shown, with almost the same configuration. Is possible.
