  Please refer to FIG. As shown in FIGS. 1 to 5, the bidirectional drawer positioning device according to an embodiment of the present invention includes at least a housing 10, a locking device 20, and an interlocking member 40.

  The housing 10 is a hollow box-type cabinet, and accommodates therein a plurality of bidirectional drawers 11 arranged in sequence up and down. A positioning convex column 13 is provided at the center of the outer surface of each drawer 11, and the inner wall surfaces on both sides of the housing 10 correspond to the outer surfaces of each drawer 11, respectively. A rail 12 is attached, each drawer 11 is slid in the housing 10, and handles 111 used for pulling each drawer 11 in both the left and right directions are provided at both ends of the drawer 11 (this technique is a conventional technique). Therefore, the second fastening wall 102 protrudes from the inner wall surface 101 of the housing 10.

  The locking device 20 includes a slide groove 21, an interlocking frame 22, a lock member 23, and a plurality of locking members 24.

  The slide groove 21 has a long concave groove and is fixed vertically to the central portion of the inner wall of the housing 10, and first fastening walls 211 are extended on both side walls of the slide groove 21. Yes. A second hook portion 212 is fixed to the top end of the slide groove 21 on one side. The second hook portion 212 has a second hook hole 2121.

  The interlocking frame 22 has a downward U-shaped plate structure, is slid and fitted into the slide groove 21, and a plurality of long piece-like positioning members 25 are attached to the interlocking frame 22 and are attached to the slide groove. 21 is positioned. That is, the both ends of each positioning member 25 are screwed onto the first fastening wall 211 of the slide groove 21, and the interlocking frame 22 is slid only in the vertical direction within the slide groove 21. A bent stopper portion 222 is extended near the top end, and a first hook portion 223 is fixed to one side top end of the interlocking frame 22. The first hook portion 223 has a first hook hole 2231. An elastic member 26 is attached between the first hook hole 2231 and the second hook hole 2121. The elastic member 26 may be a coil spring. A biasing force is applied between the interlocking frame 22 and the slide groove 21 by the elastic member 26. In particular, a fitting portion 224 is projected from the top edge on both sides of the interlocking frame 22. A long first opening 2241 is formed in the fitting portion 224.

  The lock member 23 is inserted in the top end side wall of the housing 10 and slides the interlocking frame 22 in the vertical direction, which includes an outer end portion 231 and an engaging portion 232. The outer end 231 is screwed onto the outer wall of the housing 10, and the user rotates the lock member 23 with the key 30. An engaging portion 232 is attached to the other end of the outer end portion 231. When the key 30 rotates the lock member 23, the engaging portion 232 rotates and contacts the top surface of the stopper portion 222 of the interlocking frame 22. The interlocking frame 22 can be slid upward and locked (see FIGS. 4 and 5).

  The locking member 24 is sequentially fixed at an appropriate location on the interlocking frame 22. The locking member 24 includes a positioning groove 241 corresponding to the positioning convex column 13. The positioning groove 241 is formed by two first edge portions 2411 formed in parallel with each other and a second edge portion 2412 connected to each first edge portion 2411. Each first edge 2411 extends vertically along the locking member 24. The second edge 2412 extends sideways along the locking member 24. The second slide guide slope 244 and the first slide guide slope 242 extend symmetrically sequentially on both sides of the positioning groove 241, and when the drawer 11 is reciprocally moved left and right, the first convex guide 13 causes the first slide guide 13 to move back and forth. It slides along the inclined surface 242 and the second slide guide inclined surface 244, guides the interlocking frame 22 and slides up and down, enters so as to correspond to the positioning concave groove 241, and is positioned by the positioning convex column 13 so as to be positioned concave. The groove 241 is locked between the first edge portions 2411 on both the left and right ends, so that the bidirectional drawer can be accurately positioned. Further, on both sides of the locking member 24, the engagement ends 243 are projected. Each locking member 24 is attached to an appropriate location on the interlocking frame 22 using each engagement end 243 (see FIG. 3).

  The interlocking member 40 includes a support frame 42 and a link rod 41.

  The support frame 42 has a first side wall 421 and a second side wall 422 which are adjacent to each other and are formed to be perpendicular to each other. A second opening 4211 is formed in the first side wall 421. The second side wall 422 is screwed to the second fastening wall 102 of the housing 10.

  The link rod 41 has a first end 411 and a second end 412. An inclined portion 4111 extends obliquely downward from the first end portion 411. A fitting bump 4112 is extended at the end of the inclined portion 4111, and the interlocking frame 22 is fitted into the first opening 2241 of the fitting portion 224. The second end 412 has a push button 415 that is fitted on the housing 10 and exposed from the housing 10. A first abutting convex column 413 is provided in a middle portion of the link rod 41 at a location away from the second end 412. The first contact convex column 413 has a first top plane 4131. After the spring 43 is fitted to the link rod 41, the link rod 41 is fitted into the second opening 4211 of the first side wall 421 of the support frame 42, and the first side wall 421 and the second side wall 421 are fitted by the spring 43. The position is constrained between the top plane 4131 of the first one. A second abutting convex column 414 is provided at a location adjacent to the second end portion 412 of the middle portion of the link rod 41. The second abutting convex column 414 has a second top plane 4141 that abuts on the housing 10, and the position of the link rod 41 is restricted within the housing 10, and the push button 415 of the link rod 41 is moved. When pressed, the locking device 20 interlocks, and positioning can be performed safely and easily in a short time.

  Reference is made to FIGS. FIG. 6 shows a state in which the drawer 11 is closed when the bidirectional drawer positioning device according to an embodiment of the present invention is actually used. When the user opens the drawer 11, first, the push button of the link rod 41 is pressed. 415 is pressed, the inclined portion 4111 of the link rod 41 slides inward along the inner edge of the first opening 2241 of the interlocking frame 22, presses the locking member 24 and the interlocking frame 22, and the lifting operation is performed. Then, after the positioning convex column 13 of the drawer 11 is disengaged from the first edge portion 2411 of the positioning groove 241 (see FIG. 7), the drawer 11 is opened by being pulled outward (see FIG. 8). When the drawer 11 is not completely pushed into the housing 10 and the location of the lock member 23 is not locked, the drawer 11 is pushed and positioned by applying force to the drawer 11. Due to the first slide guide slope 242 structure of the locking member 24, the locking member 24 is pushed smoothly, the locking member 24 and the interlocking frame 22 are raised together, and the force applied when the user closes the drawer is large. If it is too large, the positioning convex column 13 is accurately guided into the positioning concave groove 241 by the structure of the second slide guide slope 244 and the first edge 2411 of the locking member 24, and the positioning convex column 13 is locked to the locking member. 24 can be accurately fitted and positioning can be performed accurately.
