Refers to things that are generally pulled out, including drawers or tables that have been pulled out. [Prior technology] The double-track mechanism for ordering two cabinets, etc., has a mechanism with the following components ... The drawer is held on the side and installed in the drawer. · Side; and middle ... Installed in the frame (the body) between the jealous people, so that a cylindrical (cylindrical) roller or ball ZΓ. Such a machine is disclosed, for example, in Patent Document 1 below. As explained in this document, if it is pulled out in the order of 6w (a), (b2) of the document, and rotated in the reverse order, and it is stored in the reverse order, it can make the given ^ mu,. U right out. k, so that the drawer side handle / middle handle-lifting is pulled out, and the load of a moving body is also reduced during storage. K Li Ji Zhuan Zhuan (Patent Document υ JP Patent Publication No. 8_1213 [Summary of the Invention] In the case of 4 = drawing out in this order, if the intermediate rail phase m body is to be stopped, it will be due to its reaction. A kind of impact that causes the two pull-outs that are still in the pull-out action is caused to prevent the smooth and quiet operation and quiet movement of the guide rail mechanism. = The purpose of the present invention is to provide: Even in this case, can still mouth π 和 女 # In view of the above object, the double guide mechanism of the present invention 1 is a double guide mechanism provided between the body and the pull-out body accommodated in the body to smoothly pull the pull-out body out. The holding mechanism has a body side grip provided on the body side; a middle rail, which allows the rotating body to intervene between the body side grip and relatively move, and a pull body side grip provided on the pull body side. It can move relative to other intermediate bodies by intervening with the intermediate rail. It is characterized by: · the body convex part is provided on the front part of the body side handle; the body is pulled out from the body with the middle handle completely pulled out; Convex The rear end position is forwarded to the position of the middle handle corresponding to the fixed position, and the interlocking roller is installed in a rotatable manner; With the body side handle fully retracted to the middle handle, the pullout body corresponding to the position of the interlock roller is retracted. From the side-holding position to the predetermined range on the rear side, the protrusion of the pull-out body is provided; the connecting mechanism is provided to pull the pull-out body from the storage completion state to the process of bringing the linkage roller to the convex portion of the body, and the pull-out body is stored During the process, from the time when the interlocking roller leaves from the convex part of the body to the complete storage, the middle rail and the pull-out body side handle are moved together, and in other processes, the two are separated and the pull-out body is completed from the storage state. Pull out, when the interlocking roller set at the middle reaches the convex part of the body, the interlocking roller will contact the convex part of the body and the convex part of the pull-out body. The rotating body can be disc-shaped or cylindrical (cylindrical) Roller or spherical ball. If the pull-out body is pulled out from the state where it is stored, the pull-out body side rail will be pulled out together with the middle rail by the connection mechanism 6 1225777. When installed in the middle handle linkage Roller arrives at Ben The body convex part of the body side handle, the interlocking roller starts to contact between the body convex part and the body protruding part, and the connection between the middle rail and the body pulling part is released. If you pull from this position, When the pull-out body is pulled out, the interlocking roller will rotate due to the friction caused by the forward movement of the pull-out body convex portion of the side rail of the pull-out body. At this time, 'because the interlocking roller is also in contact with the convex portion of the main body, it turns —: this convex .P and then advance to the given amount of front side position, #the middle rail is pulled out a position. After the body side rail is further pulled out relative to the middle rail, it is completely pulled out. In this process, if the linkage roller starts to rotate, Pulling out the side of the body ^ # ψ, go # ^ The principle of the pull speed, the forward speed of the middle rail is reduced. Therefore, "To stop the middle rail, stop only this 1/2 speed: It is necessary to stop the middle speed of the same speed as the side rail of the pull-out body. Stop the 2 shocks to allow the puller to smoothly and quietly pull the pull-out body. The interlocking irr2 'is in the double-type guide rail mechanism described in the invention 1.周边 The peripheral part of each convex contact is formed by a soft elastic material. It is formed by a soft elastic material. It is held between the convex parts and held between the convex parts. Along with the deformation, it is possible to restore the situation of 胄 due to its material. Become sure. In addition, because of the elastic material in the third aspect of the present invention, the interlocking roller is installed in the multiple-type guide rail mechanism described above, and the gap moves in the radial direction. There is a case where the pull-out body can be pulled out or stored along the insertion axis. The linking roller is located between the convex portion 1225777 of the body and the convex portion of the pull-out body. The middle door position between the departments: the area axis) The position gap can automatically adjust the position, and ^: set 'if there is contact in the row. This restraint advances between the two convex parts. In the present invention 4, the predetermined amount at the position of the invention-made interlocking roller is short. In the double guidance mechanism described above, the predetermined range of the convex part of the pull-out body is limited ... and the predetermined amount of the Kun position, if it is out of the body, it will become necessary to move the pull-out body with the pull-out body. Choose λ-. After the engraving is evil, the middle position should be around: = short, and 'when it is to be stored, the middle rail of the predetermined range is pulled out by pulling out the convex part of the body, and it is located between the middle rail and the body ^, and the starting load is Get smaller. Therefore 'when it is to be pulled out or to be accommodated, the length of the φ body's out-body side rail is separated and moved short, because the middle rail is not adhered to the pull (pull-out body side (that is, pull-out body): The state ^ u is not pulled out significantly) The negative sign of the rotating body located between the middle rail and the body side handle is only a static load under evil conditions, which can avoid the more severe., ~, ^ R ^ ^ Chebe Ho. Therefore, the durability of the rotation-(there are a plurality of through-p rotors, but especially those near the river end) is improved. Training track Invention 5 ~ Invention 8 ’are pairs of inventions] A combination of multiple inventions selected from any of Inventions 2 and 3. In the process, even if the linkage is in the middle position of the rotation surface of the linkage roller, in the invention 5, when the pull-out or storage of the pull-out body is located between the convex part of the body and the convex part of the pull-out body, the center (pivot axis) ) Position, accuracy is not located in the two convex 1225777 'can automatically adjust the position, and' but

The compound guide mechanism provided in invention 9 is in invention 8 as long as it has the gap of the invention and is held at the side of the extended length, the linkable mechanism has a mechanism capable of rotating around the pivot axis of the connector. It can be installed in the arm-shaped link of the middle handle in a free manner; the link is provided with an engaging projection on the side facing the pull-out body side; The "backward state" can penetrate the recessed portion provided at the predetermined position of the side rail of the pull-out body; a swelling portion is provided on the side of the connector facing the side of the main body, and the swelling amount of the swelling portion enters the engaging convex portion. The state in which the concave portion and the bulging portion are facing the side of the body is set so that the engaging convex portion does not disengage from the concave portion; when the pull-out body is pulled out and the connecting roller reaches the convex portion of the body, the bulging portion is detached from the body A restraint position of a side handle is provided with a pivot axis for a coupling device. [Embodiment] Hereinafter, the present invention will be described in more detail according to the embodiment example shown in the accompanying drawings. FIG. 1 is a document cabinet (not shown) having a double guide mechanism of the present invention. Pictured) Rail machine in drawer storage state FIG. 2 is an enlarged view of a main part thereof. FIG. 3 is an enlarged cross-sectional view of an arrow line C-C of FIG. 2. In the cross section, at one end side (lower side) of the middle rail 12, through a plurality of rotating bodies 225777 arranged in the front-rear direction, that is, rollers (combination), are provided in a rectangular shape so as to surround the one end portion. The frame side handles 10 (one corner of which forms an opening). Again, while eating. On the side (upper side), a drawer side rail 14 having a rectangular shape so as to surround the one end is provided through a plurality of rotating bodies (combinations) arranged in the front-rear direction (one corner of which forms an opening) . The side rails of the frame are fixed to the frame of the document cabinet (not shown) through the bracket member, and the side rails of the frame are fixed to the drawer (not shown). In this example, the frame convex portion 1 〇τ is set in the vicinity of the end portion before the frame side is held 10, and the middle portion of the long side direction 14 is held on the side of the drawer. The drawing protrusion 14T is provided so as to protrude toward the side rail side of the frame. In the fully stored state of the drawer, 5 is mounted on the spoon middle rail corresponding to the convex part of the drawer and serves as the pivot bush 2 2. On the side of the bushing 22, an interlocking roller 20 having an inner diameter slightly larger than the outer diameter of the bushing is rotatably provided. This interlocking roller 20 is constituted by the frame body portion 20Η and the contact portion 2_.卩 'is composed of a hard synthetic material such as polyacetic acid, and the contact portion 20N is provided at a position of σ 卩 which is in contact with the convex portion 5 of the drawer. For example, a soft material such as polyurethane Elastic combination of resin materials. However, as far as the broadest scope of the present invention is concerned, as long as it is formed with good accuracy, the interlocking rollers can rotate freely within the range of ^ and the outer diameter of the bushing, χ, not divided into hard f and soft The elastic cymbal may be formed of any one of the materials. Furthermore, in this example, although the rear part of the arm-shaped connector 30 is rotated concentrically with the bushing 22 and the bushing is used as the pivot position, it can also be installed in a different position from the bushing. Its location. 1225777 In the storage state, the contact portion 2nw 1 of the interlocking roller gently abuts the drawer convex portion 14T or has a slight gap. As shown in Figure 3, the interlocking roller moves the interlocking roller to the side of the frame (lower). (Side), and the left direction creates a gap 23 on the underside of the bushing. However, under the contact portion 20N, the side collar θ India τ t J 7 member domain does not contact the frame side rail, and there is a gap. In the storage state of the pumping shoe ', the engaging convex part of the front end of the connector is penetrated into the recessed 14 hole provided at the predetermined position of the drawer side rail). In addition, a bulging portion 30T ′ is formed under the connecting member on the opposite side (lower side) of the engaging convex portion. In a state where the engaging convex portion invades the concave portion 14Η, the bulging portion is in contact with or close to the upper side of the frame side rail. The engagement convex portion cannot be separated from the concave portion. Therefore, if the drawer is pulled out, the drawer side handle and the middle rail will advance together. Continue to pull out the drawer. As shown in Figure 4, when the interlocking roller 20 installed at the middle reaches the rear end of the upper portion of the frame convex portion 10T, the bulging portion 30T is separated from the upper side of the frame side rail. Restraint. Therefore, if the drawer (drawer side handle) is to be pulled out again, the engaging convex portion 30K of the connecting device will exit the side edge behind the concave portion 14H to release the engagement with the concave portion. With this, the middle rail and the drawer side rail can be moved separately. In the state of FIG. 4, the contact portion 20N of the interlocking roller is held between the drawer convex portion 丨 4T and the frame convex portion 1 ττ, and starts. Touch and rotate the two grips (the convex part). Therefore, the interlocking roller 20 starts to rotate with the bushing 22 as a pivot, and according to a well-known principle, the intermediate execution speed is reduced to half the pull-out speed of the drawer side operation. In the state of FIG. 4, the position on the drawer side rail corresponding to the position of the interlocking roller (the central portion of the drawer projection 4ΊΓ) is represented by pi. Next, the state of further drawing is shown in FIG. 5. In this figure, the position P2 on the side rail of the drawer corresponding to the position of the 1225777 moving roller is at the rear end position under the convex part of the drawer, which indicates the moment when the rotation of the connecting roller is about to end. On the other hand, in this state, the position on the side rail of the frame corresponding to the position of the interlocking roller is indicated by W '. This position is above the convex portion of the frame. The distance 5 between the positions P1 and P2 of the above-mentioned drawer projections and the position ρm of the projections of the frame body are the same as the distance "糸 from P2. In addition, theoretically, the projections of the frame body and the drawer projections 2 required by the present invention , Respectively, at position ^, and P2, between, and between positions P1 and P2, and the respective front side extension illustrations are reserved for reservation. Therefore, in the first and fourth inventions, the stated and established The range refers to the position between positions P1, P2, and between positions P1 and P2. The state shown in Figure 5 above is the rotation end position of the interlocking roller, and also the pull-out completion position of the middle handle. To make the middle The pull-out is completed. Although not shown, a slit or the like is provided at a predetermined position such as the end of the rear end of the middle rail, so that it is locked at the engaging convex portion provided at the corresponding position of the frame side. Others may be used. The mechanism can also be easily constructed by those who are familiar with this skill. Therefore, if the drawer is continued to be pulled out later, the drawer side will move forward together with the drawer. From the state of FIG. 4 to the state of FIG. The speed is half of the drawing speed, and the middle stop is shown in Figure 5. The impact in the normal state will be lessened than when the middle rail is stopped while moving at the pull-out speed. The pull-out operation can be performed smoothly and quietly. Figure 6 is an enlarged cross-sectional view of the arrow FF in FIG. 4 The state up to Fig. 5 is the same. Only the parts that are different from Fig. 3 are explained. In Fig. 6, the interlocking light (the contact part) is pinched by the drawer convex part and the frame convex part, and the pinched part can be slightly Deformed to surely rotate between the two convex parts. Therefore, it is approximately equal to the bush 22 12 1225777, and the gap 2 3 ′ of the pivot of the interlocking roller 20 does not deviate from one axis. The bush can rotate concentrically by the aforementioned distance. The size δ, the greedy technique wfn will Φ Μ ^ into the right system, for example, a short size of 6mm. When Qiu ^ is pulled out, the role of the linking mechanism 30 and the recess will connect the drawer side rail together. With this, # 防 t + space rail is in a dangling state (large 'out drawer side handle (and heavy drawer) on the middle b space rail'. Move 'can make' the dynamic load of the rotating body between the handle and the frame side rail Decrease. = Invention, although it can also increase the distance ... to increase the length of Mei_Off, in this case, from the position where the middle rail is completely pulled out about m, the drawer side handle will move forward relative to the middle handle, because the drawer side rail is connected to the middle rail. 2 times the speed of forward, so that it will form a drape state, and the thorny dream a 4 i ^ β 1] between the middle rail and the side of the frame body, moving the body to increase the moving negative #, making the rotating body for a long time Sex decreased. In addition, if the drawer in the pulled-out state is to be stored, as shown in the state of FIG. 5, before the protrusion 14T has not started to contact the contact portion 20N of the linking roller, the drawer side rail can freely store the middle rail along the middle rail. Move backwards. Then, until the state shown in FIG. 4, “moving at a speed ratio of 2: 1 by the action of an interlocking roller, and then the coupling device 30 is locked at the recess 1 and occupied” and moved backward together with the intermediate rail is completed. Shelves. In the case where the drawer side handle and the middle handle move back and forth freely, although the rotating body intervening between the drawer side rail and the intermediate rail may generate a force to move the middle rail backward, the rotating body interposed between the intermediate handle and the frame side rail may cause On the top, there is strong pressure (caused by the drawer side rail and drawer hanging together) acting 'Even if the drawer side rail moves back, the middle rail will not move easily, and the 13 1325777 often stops. Therefore, in this case, after the drawer side rail is stored and returned to the shape shown in Figure 5, the middle rail starts to move backward at half the speed of the drawer side rail's storage speed by the action of the interlocking roller, and moves to Figure 4. Of the state. If the middle rail moves back to this point, the rear surface 30TF of the bulging portion 30τ of the coupling 30 will interfere with the front end edge 10F of the frame side and be pushed up, so that the engaging convex portion Xie invades the concave portion 14H. The rails move backwards (at the same speed) as the drawer side rails-at the same speed. Therefore, in this case, it is possible to reduce the impact at the beginning of the retraction of the middle rail compared to the case where the middle rail stops and suddenly starts to retreat at the same speed together with the drawer side grip. When the drawer is stored, even if the middle rail is retracted due to friction, the interference between the bulging portion 30T of the above-mentioned connector and the front edge 10F of the side of the frame body moves to the side where the recess UH of the side rail is drawn. Until the position of the engaging projection of the coupling device, the back of the intermediate rail is restricted. If it is in a facing state, the engaging projection invades the concave portion, and the middle rail moves backward together with the draw-out side rail to complete the flexion and storage. The connection mechanism can also be any mechanism other than the mechanism having the above-mentioned connection device 30 and the recessed part "Η, and can be selected arbitrarily.
