Description of the invention (/> [Detailed description of the invention] [Technical field to which the invention belongs] The present invention relates to a locking mechanism to prevent a drawer such as a cabinet from being washed out due to the reaction caused by the impact during storage. . So 'is not limited to cabinets, as long as there are drawers, such as desks, etc. [Known Technology] For example, in the office furniture that can store files, etc., sometimes the drawer is pulled out, because Push too hard and close the drawer vigorously. At this time, the drawer returns due to the reaction force of the rebound from the cabinet side at the end of the storage. So if the drawer rushes out, it will form an obstacle, and sometimes the furniture will still Because of this, the drawer must be pushed in and closed again. In this impactful storage situation, in order to prevent the stored drawer from rebounding and rushing out, a latch mechanism will be provided to lock the stored drawer to On the cabinet side. This mechanism is a lever member provided on the handle on the front of the drawer, which can be unlocked by pulling out the drawer at the same time while pulling it out by hand. [Invention to be solved] In the case of the above-mentioned latch mechanism, since a lever member must be provided on the handle in front of the drawer, there are limitations in the shape and design, and there is a disadvantage that a handle of any shape cannot be formed. In view of this, the object of the present invention, A mechanism other than the method of putting a lever on the handle on the front of the drawer is used to prevent the drawer from being rushed out due to the impactful storage behavior. [Means for Solving the Problem] According to the above object, the present invention provides a drawer card Non-governmental organizations, 4 paper sizes are applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------------- Order ------- ----- (Please read the precautions on the back before filling this page) 592651 A7 ____B7___ V. Description of the invention (1) It is characterized by a pivot, which is set on the drawer and extends leftward or rightward or upward. ; The rotating member is installed to be able to rotate around the pivot axis, as long as it does not withstand the external force above the predetermined pressure, it has a stable state. Once it is subjected to the external force above the predetermined pressure, it rotates so that its center of gravity moves backward, The given rotation position Rotation will be restricted by the aforementioned drawer; and the locking part is provided on the cabinet housing the goose, and the position where the drawer is advanced forward from its storage position can be restricted to the rotation of the aforementioned predetermined rotational position In this case, when the cabinet is set, the side where the drawer is pulled out is called the front side, the side opposite to the storage side is called the rear side, and the vertical height of the cabinet is called the upper side. The lower part is called the lower side, and the left-hand side of the person facing the front of the cabinet is called the left side, and the right-hand side is called the right side. The meaning of being placed on the drawer refers to the drawer itself or the drawer. The installed components are the same as others. Since the rotating member is provided on the drawer so as to freely rotate around the pivot (extending in the up-down direction or left-right direction), when the drawer is pushed in strongly, it is in the storage position. When an impact force is applied, the rotating member is subjected to an inertial force of more than a predetermined value in the pushing direction (rear), and its stable state will be disintegrated. Although it will rotate to the center of gravity and move backward, the rotating position will be limited. Positioning On. Moreover, although the drawer will advance due to the rebound effect, the rotating member restricted by the drawer will be locked by the locking portion installed on the cabinet body, so that the drawer's forward movement due to the rebound effect is affected at this position. limit. Also, even if the drawer stops at a slightly protruding position, as long as the drawer is pushed in 5 paper sizes, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied ----------- -------- Order --------- Line— (Please read the precautions on the back before filling this page) 592651 A7 _B7____ V. Description of the invention ($), the rotating component will be released and The engaging state of the locking portion is restored to a stable state, and therefore, the drawer can be opened normally as usual afterwards. In item 2 of the scope of the patent application, a drawer locking mechanism is provided, which is characterized in that it is provided with a pivot on a moving member that moves in the same direction as the drawer by friction, and moves up and down or left and right Extending in the direction; Rotating member is installed to be rotatable around the pivot axis, as long as it does not withstand external force above the predetermined threshold, it will have a stable state. Once it is subjected to external force above the predetermined threshold, it will rotate to its center of gravity. Move, the rear rotation will be restricted by the aforementioned movement position at the predetermined rotation position; and the locking portion is provided on the cabinet housing the drawer, and the position after the drawer is slightly forward from its storage position can be moved The rotation member restricted to the predetermined rotation position is locked. Since the rotating member that can freely rotate around the pivot (extending in the up-down direction or the left-right direction) is provided on the moving member (moving in the same direction as the pumping goose by friction), when the drawer is pushed in strongly, it is in the storage position. When an impact force is applied, when the rotating member receives an inertial force of more than a predetermined value in the pushing-in direction (rear), its stable state will be disintegrated. Although it will rotate to the center of gravity and move backward, the rotation will be limited to In the given position. In addition, although the drawer and the moving member will advance due to the rebound effect, the rotating member restricted by the moving member will be locked by the locking portion installed on the cabinet, so that the moving member moves forward in this position. Restricted location. At this time, although the drawer slightly advances due to the frictional force caused by the sliding of the moving member, it will immediately stop due to the sliding friction. Generally, in this state, the drawer will protrude beyond the storage position. 6 paper sizes are applicable to China National Standard (CNS) A4 (210 X 297 public love) ----------------- i — — Order --------- line (please read the notes on the back before filling this page) ^ _ 592651 A7 _ — —_B7 ___ V. Description of the invention (★) But as long as you push in, The moving member can be driven back by friction. At this time, the rotating member will release the locking relationship with the locking portion and return to a stable state. 'After that, the drawer can be pulled out as normal. Item 3 of the scope of patent application provides a locking mechanism for a drawer such as item 1 of the scope of patent application, in which the position slightly forward is placed on the drawer or is linked to the drawer The wheels on the moving member moving in the same direction are within the operating range of the sliding mechanism. Even if the rebound of the drawer is restricted and the drawer is about to stop at a slightly forward position, as long as the wheels in this position are within the operating range of the slide-in mechanism, the drawer will automatically retreat and return to the original storage. position. In item 4 of the scope of patent application, a lock mechanism for a drawer as provided in item 2 of the scope of patent application is provided, in which the wheel set on the moving member is located in the operating range of the slide-in mechanism in the slightly forward position. Inside. Even if the advancement of the moving member is restricted due to the rebound of the drawer, and the moving member is about to stop at a slightly forward position, as long as the wheel at that position is within the operating range of the sliding mechanism, the moving member Will automatically retreat back to the original storage position. At this time, the drawer also moves backward with the movement of the moving member by friction. However, the pumping geese move slightly forward than the moving members due to sliding when rebounding and advancing. Although the drawer only protrudes slightly from the storage position, the amount of advance is small because of sliding friction rather than rotational friction. Therefore, it is possible to prevent the furniture such as a cabinet from falling over. 7 ------------------- Order --------- Line 丨 · (Please read the precautions on the back before filling this page) This paper size applies China National Standard (CNS) A4 specification (210 X 297 mm) 592651 A7 ^ _B7 ___ V.

A pivot shaft 24 is protruded on the seat member, and the pivot shaft 24 extends in the left-right direction of the cabinet. On the pivoting member 26 (having a hole 26H near the lower end, passing through the pivot 24) near the pivot, when the drawer is stored, on the front side of the cabinet, There is a front wall portion 26B extending substantially upward, and a rear side extending substantially upward is also provided on the rear side of the cabinet. ----- 线 丨 丨 # (Please read the notes on the back before filling out this page) _ This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 592651 A7 _ __B7___ 5. Description of the invention (What) The wall portions 26A, 26B, 26A and the bottom surface 26T define a recess 26U in common, and the opening directions are upward and right, respectively. Further, at the upper end of the rear side wall portion, a claw-shaped rotating member locking portion 26K is formed so that when the drawer is accommodated, the tip portion is substantially upward and extends substantially backward. A spherical body 30 such as a metal having a large specific gravity is housed in the aforementioned recessed portion as a rotating body, and the outer frame member 28 is fixed to the seat member with a screw B2 from the right side. Further, the upper portion 28K of the outer frame member is bent toward the seat member, and the front end of the upper portion 28K is inserted into the hole 22H of the seat member to be locked. Both the upper opening and the right opening of the recessed portion are blocked by the outer frame member to prevent the ball from falling out of the recessed portion. The hole 28H receives and supports the end of the aforementioned pivot. The front and rear wall portions of the rotating member are positioned to sandwich the upper portion 28K: Before the front side edge K2 of the upper frame member upper portion 28K (for restricting the rotating member) abuts against the front side wall portion 26B, the rotating member can Similarly, before the rear side edge K2 of the upper frame member upper portion 28K abuts against the rear side wall portion 26A, the rotation member can be rotated to move the center of gravity forward. The position of the center of gravity of the rotating member is higher than the pivot 24 here. And when the front side wall portion 26B of the rotating member abuts the front side edge K2 of the upper portion 28K of the outer frame member 28, the position of the center of gravity of the ball 30 combined with the ball 30 is more than the position of the lead straight line L1 through the pivot 24 For the rear, the rotating member 26 is settled in this state.

Once the drawer is pushed back violently in the direction R, the drawer will be suddenly blocked in the predetermined storage position in the cabinet and will be impacted, and then forward again. At this time, due to the inertia, the rotation member 46 is rotated to cause the locking portion 46B and the leg portion 46A to move backward, so that the locking portion 46B enters the specific hole 44H on the foremost side, and the end portion of the locking portion is directed to the specific hole. 44H protrudes below. However, the rearward rotation of the rotating member is restricted because it comes into contact with a part of the rear wall portion of the surrounding wall that defines the hole 44H. At this time, 'Because the drawer moves forward due to the rebound, the aforementioned specific hole 44H 10 ------------------- IT --------- ^ ( Please read the precautions on the back before filling in this page) ______ & Zhang's scale is applicable to Zhongguanjia Standard (CNS) A4 (210 X 297 public love) I ~ 592651 A7 ___B7_ V. The back wall of the description of the invention While pushing the locking portion 46B of the rotating member 46 forward, the abutting portion engages with the end of the rotating structure-side locking portion 26K of the cabinet-side rotating member 26 in the aforementioned stable state. Later, due to the impact of the drawer moving forward, the cabinet-side rotating member 26 is rotated while pushing the center of gravity to move forward. The rear side wall portion 26A of the rotating member 26 and the rear side of the outer frame member 28 The edge K1 abuts, so that the rotation of the cabinet-side rotating member 26 and the forward movement of the drawer are restricted while the two locking portions 26K and 46B remain engaged. In a restricted state, although the drawer protrudes slightly forward, after that, the drawer may sometimes return to the storage position due to the reaction, and if the slide-in structure (described later) is provided, the drawer can also automatically Return to the stowed position. In this way, if the drawer returns to the storage position, the locking portion 46B will be separated from the locking portion 26K. Since the leg portion 46A is heavier than the locking portion 46B, the locking portion 46 will rotate clockwise around the pivot 48 as shown in FIG. 4. The foot portion 46A ′ is stabilized by abutting against the lower plate-like portion 44 by rotation. The locking mechanism of the drawer mentioned in the first embodiment is both a locking mechanism for preventing the drawer from bursting out due to an earthquake and a locking mechanism for the purpose of this application, that is, preventing the drawer from being pushed in violently. Ejected locking mechanism. However, the following embodiment is a simplification of the first embodiment, and only has a locking mechanism for preventing the drawer from being ejected by being pushed in strongly, as shown in Figs. 5 and 6. Differences from the first embodiment will be described here. First, as for the drawer side, since the hole 44H 'provided in the lower side plate-like portion 44' of the drawer-side seat member 42 'is only a specific hole, the length of the seat member 42' becomes short.

Description of the invention (?) Fold up The claw-shaped member 18K is formed to be used as a locking portion. When the drawer is pushed in violently, the situation is the same as in the first embodiment, the rotating member 46 rotates, and the locking portion 46B abuts against a part of the rear wall of the peripheral wall portion of the partitioning hole 44H '. At this time, the drawer will move forward due to the rebound, and the locking portion 46B of the rotating member will be engaged with the locking portion 18K of the claw-shaped member as shown in FIG. 6, thereby restricting the drawer and no longer moving forward. mobile. At this time, even if the drawer is in a stopped state, as long as the drawer is pushed in again, the rotating member 46 can be restored to its free state and returned to the stable state as shown in Fig. 5 so that the drawing can be pulled out as usual. As shown in FIG. 6, a drawer mechanism of a general drawer is provided with a moving rail member 50 that moves in the moving direction of the drawer, and a wheel 52 mounted on the drawer mechanism is formed along an inclined portion 54 (formed in a fixed direction) that is inclined downward and rearward. The fixed rail member 10 ') on the cabinet side rotates backward. This is called a slide-in mechanism. When the drawer is stored, even if the drawer is not fully stored, as long as it is slightly protruding, the wheel is located on the inclined portion 54 due to the weight of the drawer, and the wheel is turned back along the inclined portion 54 to hold the drawer. In a fully stowed state. If such a mechanism is provided, as shown in FIG. 6, the drawer is locked when it rebounds, and its punching out is restricted. After that, the drawer will automatically follow the movement of the moving rail member 50 by the slide-in mechanism. Go back and return to the storage state naturally. This case is also applicable to the third embodiment described later. Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 7 to 9. This means that the moving rail member 50 also mentioned in Fig. 6 moves in the same direction as the drawer moves.

In the description of the invention (P), the fixed rail member 10 extending in the front-back direction is fixed. A wheel 52 is mounted on the moving rail member 50, and the wheel is rotated on the lower surface 10'D of the fixed rail member 10 ', and the moving rail member 50 can move forward and backward simultaneously. The drawer 14 is carried by the aforementioned wheel 52. When the drawing goose is pulled out, the weight of the drawer causes the wheel 52 to generate frictional force, and thus rotates. As a result, the moving rail member 50 moves in the same direction as the drawer. The moving speed will be 1/2 of the moving speed of the drawer, which is common knowledge in institutions. At a predetermined position on the rear of the moving rail member 50, a pivot shaft 48 extending in the left-right direction is provided, and a pivot member 46 is rotatably mounted around the pivot shaft. The structure of the rotating member 46 is the same as that of the rotating member of the first embodiment, and its feet are placed in a stable state by being placed on the lower plate-like portion 56 of the moving rail member 50. The lower plate-like portion 56 has an opening hole. When the rotating member 46 is rotated, a locking portion of the lower plate-shaped portion 56 protrudes downward from the opening hole. In addition, at a predetermined position on the rear portion of the lower surface portion 10'D of the fixed rail member 10 ', a latching portion 10, K formed by punching out from the lower portion of the member 10 is provided. Therefore, when the drawer is pushed in vigorously, the moving track member will also be moved in the same direction, and the rear rotation in the storage position is suddenly restricted, so that the rotating member 46 will be as in the first embodiment of the week. Rotating by inertial force, the locking portion will abut against a part of the rear wall of the surrounding wall that defines the opening hole. In this state, the drawer and the moving track member will advance due to the rebound action, and the locking portion of the rotating member and the aforementioned locking portion 13 This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --------------— (Please read the notes on the back before filling out this page) _ 592651 A7 ___B7___ V. Description of the invention (i 丨) 10 'K-phase engagement, moving the track member 50 cannot be moved forward due to restrictions. From this state, although the drawer 14 moves forward while sliding on the wheel 52, it stops immediately due to sliding friction. Since the aforementioned locking portion 10'K is provided near the pivot 48 provided on the moving rail member, the rebound will be restricted immediately, so that the drawer 14 can be stopped without advancing too much. If the drawer in this position is pushed in, the moving rail member 10 'will also be pushed in, and the rotating member 46 will be separated from the locking portion 10' K and restored to freedom, returning to the stable state shown in FIG. 8, And pull out the drawer as usual. [Effects of the Invention] It is clear from the above description that according to the present invention, it is possible to prevent the drawer from rebounding due to shock storage by using a mechanism other than the lever method incorporated in the handle on the front of the drawer.
