Description of the invention ()) / Engage with the guide member on the side of the pillar to make the pillar move toward the locking position. Since the pillars in this position are held by the holding mechanism, the other drawers cannot be pulled out afterwards. When the drawer is to be pulled out, the drawer-side guide member is engaged with the retreat member to retreat upward. The interlocking restriction member also moves upward. When the restricting member moved above is pulled out, when the drawer on the upper side of the drawer is pulled out, it is engaged with the upper drawer to stop the pulling out operation. Since the drawer-side guide member of the stopped drawer (upper drawer) is engaged with the pillar-side guide member, the pillar body cannot move up and down. Therefore, the pillar cannot be moved with the pull-out operation of the lower drawer, and as a result, the two drawers cannot be pulled out together (roughly together). For example, in a 5-segment cabinet, if the aforementioned upper drawer is the uppermost drawer, the lower drawer is the second drawer from the upper side, that is, if a withdrawal member is provided for the second drawer from the upper side, corresponding to the uppermost drawer. If the drawer is provided with a restricting member, the uppermost two-stage drawer with the highest risk of falling can be prevented from being pulled out (approximately) at the same time, thereby improving safety. Of course, this method can be applied to other drawers as well as all drawers. The second item in the scope of patent application is relative to the first item in the scope of patent application, where the movement of the connecting body is downwardly opposite. Although an elastic pressing device for springing upward is required, the effects and effects are the same as those of the application. The first scope of the patent is the same. The scope of application for patents No. 3 and 4 is to set up joints for all adjacent drawer pairs of multi-segment drawers, which can more effectively prevent the cabinet from falling down due to carelessness.

INTRODUCTION TO (A) INSTALLATION --- (Please read the precautions on the back before filling out this page) Any of the ~ items attached to the cabinet with a pull-out prevention device, where the drawer-side guide member is A lever member protruding to the side of the drawer, the pillar-side guide member is a block having an inclined groove to guide the lever member, and the retreating member and the restricting member can be held in the block, and are vertically opposite to the block. It can move freely within a predetermined range, and the retreat member and the retreat member of a connected body are connected to each other by a rod member. Since the evacuation member and the restricting member can be held in the block and move freely within a predetermined range relative to the block, the evacuation member and the restricting member can be installed in advance as a block before being installed in the cabinet body. The guide body is a pillar-side guide member, and this mounting body is mounted on the pillar. Furthermore, since the retreating member and the restricting member can move freely within a predetermined range with respect to the block, the mounting bodies are mounted on the pillars. In the state, it is possible to install the insertion rod member in the retreating member and the restricting member between adjacent blocks. Since the pillar body assembled in this way can be incorporated into the cabinet body, the assembly operation can be performed smoothly. The scope of patent application No. 6 is a cabinet with a simultaneous pull-out prevention device, which has a plurality of drawers, and is characterized by having: a drawer-side guide member attached to each drawer; an employee of the Intellectual Property Bureau of the Ministry of Economic Affairs The consumer cooperative prints pillars that can move up and down with respect to the cabinet body; pillar-side guide members are provided on the pillars corresponding to each drawer-side guide member and engage with the drawer-side guide member when the drawer is pulled out. Move the aforementioned pillar from the normal position to the locked position of the drawer maintaining the storage position, and when the drawer that has been pulled out is stored, the pillar is restored to the original normal position by engaging with the drawer-side guide member; 7 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 592650 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (j) 'The holding mechanism will be moved to the locked position The pillar is held in this position, and the retaining is released under the predetermined force that restores the pillar in the direction of the original normal position; the linear member is longitudinally arranged Restriction mechanism, keep the end of the linear member with a certain amount of slack, or connect at least one end of the linear member to the spring mechanism, and reduce the slack of the linear member in normal times And the extension of the spring mechanism is limited to a predetermined amount of extension; and the retracting member, when the drawer-side guide member and the corresponding pillar-side guide member are engaged to pull out the drawer, the guide member on either side is pulled out. The lead member engages and retreats along with the movement, and is not supported by the shaft. Relative to the retreat member, the aforementioned linear member is continuously locked and flexed at least during the retreat. In this flexed state, it cannot be guaranteed Pulling out the slackness of the linear member of the other drawer makes the other retracting member of the engaging linear member corresponding to the other drawer unable to evade. It differs from the structures in the first to fifth aspects of the patent application in that it uses a retracting member and a linear member (and a spring device and a restricting device) instead of the connection body (and the spring mechanism). When a drawer is pulled out, the slackness of the wire-shaped member corresponds to the retreat of the retreat member, so that the retreat member can move in retreat, but when the drawer is pulled out in this retracted state, the slack of the linear member That is to say, the evacuation member corresponding to the other drawer cannot make the necessary evacuation movement. Therefore, it is not possible to (roughly) pull out two drawers at the same time. This linear member can be provided only in a certain adjacent drawer room, or in all drawer rooms, that is, between the uppermost drawer and the lowermost drawer.

Description of the invention (f) 'For each connecting rod member, the restricting member provided at the upper end and the The retreating members at the lower end are collectively referred to as a coupling body, and each member of the coupling body moves together in the vertical direction. Although they are called together, they can be completely simultaneous or substantially simultaneous. That is, as for the connecting rod member, if the restricting member and the retreating member are fixed by means of adhesion or the like, it can be referred to as completely simultaneous movement, but is only inserted into the engagement relationship without being adhered. When the end of the connecting rod member in the hole can move up and down slightly with some gaps, although it is slightly delayed, it may be about the same time. A predetermined hole 14K is provided in the flange portion of the upper end portion of the pillar 14, and the holding member TB is press-fitted so that the engaging portion TB on the side thereof is locked and mounted on the pillar. This holding member TB is provided with a hole TH in a side portion thereof, into which a coil spring CS and an operating member KB are inserted. A cam surface KS is provided at a predetermined position of the operating member KB. In the assembled state, the coil spring urges the operating member to the left in FIG. 2. An L-shaped engaging hole LH is provided at a predetermined position on the front portion of the holding member TB. The operation of the above structure when the drawer is pulled out will be described below. Fig. 3 is a diagram illustrating the operation of the connected body and the like when the drawer 12C is pulled out as an example. (A) is a side view of the state of each drawer from the area of the blocks 14B to 14C in the storage state. Pulling out the drawer 12C means that the lever member 16C protruding from the side moves in the left direction of FIG. 3. In FIG. 3, the area drawn by diagonal lines on each member is located in the inclined grooves of each block. When each rod member passes through each inclined groove, the engaged portion is displayed. The same applies to FIGS. 4 and 5. In the state of Fig. 3 (a), the restriction member at the lower position of each block and the retreat member at the upper position are located at the wall surface below the inclined groove (also the restriction member.

On the inclined surface Position) are in contact with each other. If the state of (a) is slightly pulled out of the drawer 12C, it becomes the state of (b). That is, the upper wall surface of the inclined groove 14CK inclined on the front is pushed, and the block is determined by the amount of pull out. The body 14C is pushed upwards. Since the pillar 14 moves up and down together with the block 14C, the pillar 14 rises this component. In addition, the rod member 16C contacts and engages below the retreating member 14CT. Therefore, the retreating member 14CT rises this component and transmits The limiting member 14BR of the upper block MB inserted into the connecting rod member BC rises this component, and this component is pushed up by the retreating member 14BT into the block HB. In this way, the connecting rod member AB also rises, and the restriction of the block 14A increases. Building 14AR also rose (C) shows the state where the drawer is further pulled out, through the block 14C, the pillar 14 further rises, and the retreat member 14CT and the members of the connecting body above it further rise, and the inclined groove 14CK is substantially fully opened. At the same time, the restriction members 14BR and MAR of all the blocks 14B and 14A above the block 14C are in a state of blocking the inclined grooves of the blocks HB and HA. If the drawer 12C is further pulled out from the state of (C), the block The body 14C is raised to the uppermost position and the drawer is completely pulled out. As shown in FIG. 5 (C) of the holding mechanism described later, the pillar is held at the uppermost position. This upper position is the locking position. As described above, the drawer is fully pulled After exiting, each connection body drops due to gravity and returns to its original relative position relative to the block. If you want to make this recovery more reliable, you can connect elastic members such as coil springs to any member of each connection body One end, and the other end is connected to the pillar or each block, so that the structure is constantly pressed downward. As mentioned above, because a drawer 12C is pulled out, the pillar is held at the locking position 13 ^ paper rule; 5¾ China Home Standard (CNS) A4 Specification (210 X 297_mm) (Please read the precautions on the back before filling this page) ·! · Binding: Printed by the Intellectual Property Bureau Staff Consumer Cooperative of the Ministry of Economy 592650 A7 B7 V.

Therefore, the lever member cannot enter the inclined groove of each block. That is, you cannot pull out another drawer. A state where the lever member cannot enter the inclined groove of the block is shown in Fig. 3 (c). On the other hand, when the drawer 12C is stored, the lever member 16C presses the lower wall surface of the inclined groove HCK, so that the aforementioned holding mechanism releases its holding force and lowers the stay 14 so that it can be stored. Although the above-mentioned action relationship between drawers and pillars is within the scope of conventional technology, the above-mentioned actions of the connecting bodies of the key institutions in this case will not cause any obstacle to the customary actions of drawers and pillars (and each block). , To ensure the normal operation of the learned action. That is, this case is a structure that adds a connection body to a conventional basic structure. Since it is based on a reliable structure based on past experience, the operation reliability of this cabinet is high. Line · Next, a case where two drawers cannot be pulled out simultaneously (including substantially simultaneously) will be described with reference to FIG. 4. The relationship between the lever member 16C and the retreat member MCT in Fig. 4 (a) is substantially the same as that in Fig. 3 (b). At this time, if the drawer 12B above the drawing 12C which is being pulled out is also pulled out, the lever member 16B can engage with the retreating member 14BT appearing in the inclined groove and advance at the same time. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, if the right drawer 12C is pulled out to the state of FIG. 4 (b), the retraction member 14CT will be fully pushed to the retreat position. As a result, the upper limit The member HBR rises and completely blocks the inclined groove of the upper block 14B. Therefore, the lever member 16B of the drawer 12B cannot continue to move forward. That is, the lever member 16B will be caught in the inclined groove of the block 14B, and the pillar 14 itself will be locked in this position. As a result, the block 14C cannot be further increased. 14 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 592650 A7 _____B7 V. Description of the invention (fl) The drawer 12C cannot be pulled out. That is, to prevent two drawers from being pulled out at the same time. When pulling out any two drawers, if the lower drawer is considered as the lower drawer in FIG. 4 and the upper drawer to be pulled out is used as the upper drawer in FIG. 4, That is, it can be prevented that any two drawers can be pulled out at the same time. Of course, you cannot pull out more than three drawers at the same time. Although the above embodiment is a structure in which the pillar is moved to the upper side, if the inclined groove is made as a forward rising groove, the structure can be moved to the lower side by the pulling operation and held by the holding mechanism, and the same connection can also be used. The body prevents simultaneous withdrawal. That is, the upper side in FIG. 2 may be set to the lower side. At this time, in order to return each link to its original upper position, one end of a spring member such as a coil spring that can at least press the linking force and constantly spring upwards can be connected to any of the links, It is sufficient to connect the other end to the pillar or block. An example is shown in FIG. 8. Coil springs 24 ', 24 "are provided therein, and one end of the coil spring is respectively attached to a retraction member 14CT connected to the upper block MC by a connecting rod member BC and a restriction member 14BR held to the lower block MB. The other end of the connecting rod member BC is mounted on the pillar 14. The two coil springs symmetrically pull the connecting body diagonally upward with the same force. The other connecting rod members LD and AB are also provided with the same Coil spring. The purpose of installing a coil spring with the same spring pressure in a symmetrical manner is to make the movement of the connecting body smooth, but it can also be configured with only one coil spring. It can also be an elastic member other than a coil spring. Unlike this For example, coil springs and the like can be provided only on the lowermost connecting body (the connecting rod member AB), but not on other connecting bodies.

Hair The explanation (η) is because the coil spring or the like provided on the lowermost joint can be used to apply upward spring pressure to all three joints. Moreover, even if the pillar moves to the upper side, it can also be retreated. The member is retracted to the lower side relative to the pillar, and the restricting member is connected below it. In this case, the member needs to be pressed. Also, as described above, this embodiment can also be made upside down. Although the joints or blocks need not be the same However, if they are the same, they can be molded with one mold, which helps reduce costs. The following other forms are also the same. The following describes the holding mechanism. Figure 7 shows the interior of the upper left of the cabinet of Figure 1 viewed from the front of the cabinet. Figure. When the key is inserted into the lock mechanism KY shown in Figure 1 and rotated, the lock rod KYK extending in the left-right direction of the cabinet will rotate, and at a position offset from this rotation center axis C0, it is provided to rotate with the k lock rod 'Question-like protrusion-shaped engagement member 22 extending in the left-right direction. 〇 FIG. 6 is a view of FIG. 7 viewed from the right side, and an L-shaped engagement hole is provided at a predetermined position on the front portion of the holding member TB. In LH, the above-mentioned protruding engaging member 22 is engaged. (A) In the state where the pillar 14 is in the normal position below, each drawer can be pulled out. If this situation is locked, it will become (b). That is, the protruding engagement member 22 is rotated approximately half a turn to the upper position. At this time, the retaining member TB and the stay 14 are pulled up and held together by engaging with the L-shaped engagement hole LH. Further, If the pillar 14 is pushed up from the state of U), the protruding engaging member 22 is pressed on the cam surface KS of the action member KB while passing 16 paper sizes.

Description of the invention (M) The longitudinal hole of the L-shaped engaging hole is relatively moved to the bottom. Since the actuating member KB having a cam surface is urged to the left in FIG. 6 by the coil spring CS, the actuating member that has been pressed by the urging force is pushed to the right and relatively moved downward at the same time. Then, when it reaches the lower side of the cam surface, the operating member will return to its original position due to the spring pressure of the coil spring. The state where the pillar 14 reaches the uppermost position is (C). This state (C) is maintained by the spring force of the coil spring CS. However, if the pillar is lowered with a force that exceeds the elastic pressure, even if the moving member KB continues to move to the right, it returns to the state of (a). Fig. 5 is a diagram for explaining the structure for preventing the pull-out while using the linear member 20 that can be flexed laterally instead of the embodiment in which the connection body is used. The linear member 20 may be a string or a chain. (A), (b), and (c) of each drawing illustrate the engagement relationship between the rod member 16C of the drawer 12C and the inclined groove block 14C ', and the upper part of each drawing is a view of the structure of the lower drawing viewed from above. The linear member 20 is provided between two flange portions of the pillar 14 in the form shown in Fig. 2 and extends in the vertical direction. It can only be arranged between two adjacent drawers, or if the length exceeds the aforementioned length, in this embodiment, it is set vertically from the height position corresponding to the uppermost drawer to the height position corresponding to the lowermost drawer, with a predetermined slack 'The upper and lower ends can be held on the cabinet body 10 or on the pillar 14. If it is not suitable to have slack in general, at least one end may be provided with a spring member such as a coil spring that applies elastic pressure to the linear member to keep the linear member in a suspended state, or reduce the amount of deflection in normal times.

If the drawer 12C is slightly pulled out from the state (a), the state (b) is obtained. That is, a state where the lever member 16C protruding from the side of the drawer comes into contact with the retreat member. As in the aforementioned embodiment, the pillar 14 moves upward. Secondly, if one is pulled out, it becomes the state (c). That is, the lever member 16C is in a state where the retraction member is retracted to the maximum extent. The head of the retreating member is exposed from the end of the inclined hole GM, and the retreating member is held by the flange portion HF1 of the pillar or another member 15 arranged to block the C-shaped space of the pillar so that it cannot fall. If only the drop-holding is performed, the inclined hole GM can be ended near the end of the convex portion so as not to be opened to the outside of the convex portion PT. However, for the convenience of assembly of the retreating member, the inclined hole is directed toward the convex portion It's open outside. It can be known from (b) and (c) that the linear member 20 passing through the groove is pulled to the head of the retreating member corresponding to the retreating distance of the retreating member toward the convex portion, and the head bent into a C shape. Snap. Therefore, it is possible to retreat within the range of possible slack under the action of the slackness of the linear member and the action of the spring member and the restricting mechanism. The aforementioned predetermined amount of slack is approximately two times or more and less than four times the retraction distance of the retraction member when a drawer is pulled out when the retraction member is a top-bottom parallel member.

(c) In the state of the position, if any other drawer is to be pulled out, the possible length of the linear member 20 is more than twice the retreat amount. For example, although the other drawer can be pulled out to (b) State degree 'but cannot be pulled out to state (c). This is because the amount of slack is not satisfied and the amount of retreat is 4 times. Therefore, it is not possible to (approximately) pull out two drawers at the same time, thereby preventing accidental tipping of the cabinet. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 592650 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention ((7) 'In addition, since the pillar 14 is locked in place The position is held by the holding mechanism shown in Fig. 6 and the like, so it is impossible to pull out another drawer like the conventional one. If the linear member 20 also has a predetermined flexural rigidity, it is pulled down from the state (c). When the drawer is pulled out, a "force star" will be generated to return it to a substantially linear shape as shown in the original (a). Therefore, the retreat member also returns to the approximate original (a) position. In order to make it reliable, it is best to The spring member is connected to the linear member in the aforementioned configuration. When the drawer 12C is pulled out to store it, the lever member 16C abuts against a retreat member that returns to its original position, but is disposed in the inclined hole GM. The receding member itself is inclined along the direction of the hole GM. Furthermore, there is 14CU near the boundary between the inclined hole GM and the inclined groove 14CK, and the HCRU on the opposite side of the 14CU near the boundary portion of the extension extending from the head of the receding member. certain The degree of space, and the back-off member is formed by removing the corners of the rear end of the head, so that it can be rotated around the axis in the inclined hole as the center. Therefore, the receiving member 16C Press, rotate and retreat in the direction of storage, and retreat along the inclined hole. Based on this, the drawer can be stored smoothly. Although the above example uses the third drawer 12C as an example, the same can be used for any drawer. In addition, the above description is universal. The method of changing the inclination direction of the inclined grooves of the block to move the support column downwards is the same as the example of the use of the connection body. The mechanism illustrated in FIG. 5 can be used in inclined grooves. The convex part PT of a predetermined shape is integrally injection-molded on the block, and the retraction member can also be injection-molded and simply formed. After that, as long as the retraction member is inserted into the block, it is not necessary to apply the Chinese national standard (CNS) such as the paper size of 20 ) A4 size (210 X 297 mm).-(Please read the notes on the back before filling this page)
