  In the drawer pulling device of Patent Document 1, a substantially U-shaped concave portion in a side view formed on the front surface side of a pulling hand that can rotate around a left-right axis on the upper side of the drawer front plate (FIG. 4 of Patent Document 1). In the state where the operator puts his / her finger in (see), the latch is released and the drawer is pulled out by operating the handle. That is, when the operator puts a finger in the recess, the latch is released if the entire handle is rotated forward, and the drawer can be pulled forward in this state.

  In such a pulling device, since the space of the concave portion into which the operator puts the finger is not widened, the finger of the operator may be changed depending on the height position of the puller, the stroke before and after the drawer, and the physique of the operator. There are cases where it is difficult to perform the operation of the handle by hitting the side surface of the recess. Moreover, if the space of the concave portion is too large, the beauty of the front surface of the storage furniture, which is important as a commercial value, is impaired. Furthermore, since the entire puller is rotated to the near side with the drawer closed, the clearance between the top plate of the storage furniture and the uppermost drawer or between the upper and lower drawers is expanded, and the anti-theft performance is lowered. May be a problem.

  The present invention has been made in order to solve the above-described problems, and provides a drawer pulling device in storage furniture that can improve the operability of the pulling handle disposed on the upper side of the drawer front plate. For the purpose.

The circular engaging recesses 14a and 14a are attached to face each other. The engaging recesses 14a and 14a may be circular holes.

  Plate members 17 and 17 constituting the rotation shaft are engaged with the engagement recesses 14a and 14a of the rotation bearings 14 and 14 and are slightly shorter than the inner diameters of the engagement recesses 14a and 14a. That is, the engagement recesses 14 a and 14 a of the rotary bearings 14 and 14 are fitted on the plates 17 and 17. The plate bodies 17, 17 are formed integrally with the connection body 18 by extending the lower left and right sides of the connection body 18, which is a processed sheet metal product, outward in the left-right direction.

  According to the configuration of the rotary bearings 14 and 14, the plate bodies 17 and 17 that are the rotary shafts, and the connecting body 18, the rotary shaft and the rotary bearing can be configured with a simple configuration. Cost can be reduced. Further, since the rotary shafts 17 and 17 are made of sheet metal and the rotary bearings 14 and 14 are made of synthetic resin, noise may be generated even if the rotary shaft and the rotary bearing slide by operation of the handle body 12. And quietness can be improved.

  The pulling device 11 includes a pulling body 12 made of a synthetic resin such as polyacetal, polypropylene, polyethylene terephthalate, nylon or ABS, which can be rotated around the left-right axis on the upper side of the front plate 1 of the drawers 104 and 105, and the pulling device. A synthetic resin cover body 13 similar to the handle body 12 is provided, which is provided with a superposition portion that closes the gap caused by the rotation of the body 12. The cover body 13 may not be a separate body from the front plate 1 but may be an integral one.

  The pulling body 12 is substantially L-shaped in a side view including a horizontal plate portion 12a extending substantially horizontally in the left-right direction and a vertical plate portion 12b extending substantially vertically from the front end of the horizontal plate portion 12a. . The cover body 13 includes a horizontal cover body 13a extending in the horizontal direction in the horizontal direction on the upper side of the horizontal plate portion 12a of the handle body 12, and the horizontal direction in the vertical direction from the rear end of the horizontal cover body. And a vertical cover body 13b extending substantially in a side view.

  The pulling body 12 is integrally formed with left and right attachment portions 12c, 12c formed by hanging the rear end of the plate-like portion extending rearward, so that the attachment portions 12c, 12c are attached to the front plate 1. In a state where the left and right through holes 22 and 22 are in contact with the rear surface of the connecting body 18, the mounting screws 28 and 28 are passed through the through holes 19 and 19 of the mounting portions 12 c and 12 c to the screw holes 18 a and 18 a of the connecting body 18. By screwing, the handle body 12 is supported so as to be rotatable around the plate bodies 17 and 17 which are rotation shafts at positions spaced downward from the handle body 12.

  Since the cover body 13 is integrally formed with a box-shaped attachment portion 13c having an opening on the lower side at the rear portion thereof, the attachment portion 13c is attached to the cover body support portion 21 of the front plate 1 from above. In the fitted state, the cover body 13 is screwed into the screw holes 21b,... Of the cover body support part 21 through the through holes 20,. It is fixed to the body support part 21.

The cover body 13 and the cover body support portion 21 are firmly connected. Further, since the slits 21a,... And the reinforcing ribs 13d,... Can be used as positioning guides, the workability of the work of attaching the cover body 13 to the cover body support portion 21 of the front plate 1 can be improved. .

  Next, the configuration of the latch device 31 that is interlocked with the operation of the handle body 12 will be described. A square hole 32a is formed in the latch body 32, and a vertical portion 39a of a steel driving rod 39 is fitted into the square hole 32a. The latch body 32 is provided with a latch plate 33 and a stopper 35 protruding in the horizontal direction with a phase shift of approximately 90 °. The latch body 32, the latch plate 33, and the stopper 35 are made of synthetic resin such as polyacetal, polypropylene, polyethylene terephthalate, nylon, or ABS, and are integrally formed.

  The latch receiver 36 is made of the same synthetic resin as the latch main body 32 and the like, and is slid by engaging upper and lower engaging pieces 37 on the upper and lower sides of the notch 24, and the engaging claw 38 is engaged with the engaging hole 26. Is attached to the front plate 1. Then, by engaging the latch body 32 with the upper and lower engagement holes 36a, 36a of the latch receiver 36, the latch body 32, the latch plate 33, the stopper 35, and the drive rod 39 are supported so as to be rotatable around the vertical axis. The The upper portion of the vertical portion 39a of the drive rod 39 is also supported by a vertical hole (not shown) formed in the left side (right side in FIGS. 2 and 4) of the rotary bearing 14.

  The latch plate 33 is formed with a locking portion 33a and is elastically biased toward the left side plate 107 of the wagon body 102 by the torsion coil spring 40 with the drawers 104 and 105 closed. Therefore, since the locking portion 33a of the latch plate 33 is locked to the locking protrusion formed on the reinforcing body (not shown) attached to the inside of the left side plate 107 of the wagon body 102, the drawers 104 and 105 are closed. Thus, the latch device 31 is activated, and the drawers 104 and 105 are prevented from opening unexpectedly as described above. The latch body 32 is provided with a rotation stop 34 that restricts the rotation of the latch plate 33 in the direction of the locking protrusion at a predetermined angle.

  The drive rod 39 has a horizontal portion 39b extending inward in the left-right direction (leftward in FIG. 2) of the front plate 1 at the upper portion of the vertical portion 39a. An abutting portion 18b extending from the connecting body 18 to the front side from the rear side contacts the horizontal portion 39b.

  Next, the operations of the pulling device 11 and the latch device 31 will be described with reference to FIGS. When the puller body 12 is pulled forward as shown in FIG. 6B from the state in which the drawers 104 and 105 in FIG. 6A are closed, the puller body 12 and the connecting body 18 are plate bodies 17 and 17 that are rotating shafts. Rotate forward around. Then, the horizontal portion 39b of the drive rod 39 is pushed forward by the contact portion 18b of the coupling body 18, and the latch body 32, the latch plate 33, and the stopper 35 are also moved along with the rotation of the drive rod 39 around the vertical axis. The latch plate 33 rotates in a direction away from the locking protrusion provided on the inner side surface of the wagon body 102.

  Thus, when the handle body 12 is pulled forward, the latch device 31 is released in conjunction with the operation. Therefore, when the latch device 31 is released, the drawers 104 and 105 can be pulled out. As shown in FIG. 5, the synthetic resin stopper 35 abuts against the back surface of the steel front plate 1 to restrict the rotation of the drive rod 39, the latch plate 33, etc. Since the front end of the portion 39b is configured not to contact the back surface of the steel front plate 1, noise at the time of releasing the latch device 31 can be suppressed.

  Thus, when the latch device 31 is released and the drawers 104 and 105 are pulled out, the handle body 12 and the cover body 13 are separate, and the cover body 13 does not rotate even if the handle body 12 rotates. When the handle body 12 is rotated as shown in FIG. 6B, the operator inserts a finger between the substantially L-shaped pull body 12 and the substantially L-shaped cover body 13 in the side view. Since the space S of the concave portion that is substantially U-shaped in side view is widened, the operator's finger does not hit the pulling body 12 or the cover body 13 and the operation is not hindered.

  Further, as described above, since the rotation shaft is provided at a position spaced downward from the handle body 12, even if the handle body 12 is rotated, the posture change is small, and the horizontal plate portion 12a of the handle body 12 is horizontal. Since the gap between the cover bodies 13a hardly expands, the anti-theft performance does not deteriorate. Further, since the posture change of the handle body 12 is small as described above, the operability of the handle body 12 is further improved.

  Furthermore, as described above, the rotating shaft is provided at a position spaced downward from the handle body 12, and the connecting body 18 and the attachment portions 12c, 12c of the handle 12 are eccentrically moved backward on the upper side of the rotating shaft. Therefore, the gravitational torque around the rotating shaft by the connecting body 18 and the pulling body 12 which are rotating bodies rotating around the rotating shaft is in the direction in which the latch is applied (the direction in which the latch device 31 is activated). Works. Therefore, it is possible to weaken the spring 40 that elastically biases the latch plate 33 toward the inner surface of the wagon body 102 with the drawers 104 and 105 closed. Therefore, since the release operation of the latch device 31 can be performed with a light force, the operability of the handle body 12 is improved.

  Further, the operation of pressing the horizontal portion 39b of the drive rod 39 forward by the contact portion 18b of the connecting body 18 on the upper side of the plate bodies 17 and 17 serving as the rotation shaft to release the latch device 31 is performed on the rotation shaft. Since the handle 12 is operated by operating the handle 12 whose distance from the rotation axis is larger than the distance between the contact 18b and the corresponding contact portion 18b, the operating force of the handle 12 is reduced by the lever principle. Therefore, since the release operation of the latch device 31 can be performed with a lighter force, the operability of the handle body 12 is further improved.
