It is an expansion perspective view of the X section in the state where the back board of the container shown in 1 was removed. In FIG. 3, the description of members appearing in FIG. 4 is omitted for easy understanding of the drawing.

  With reference to these drawings, the drawer structure 1 mainly includes a container 10, an outer drawer 11 that is housed in the container 10 so as to be freely drawable, and an inner drawer 12 installed inside the outer drawer 11. It consists of. Since the outer drawer 11 is provided with the engaging members 15a and 15b and the inner drawer 12 is provided with the engaged members 16a and 16b, both are engaged in the accommodated state shown in FIG. When the outer drawer 11 is pulled out from this state in a predetermined direction (left direction in FIG. 1), the inner drawer 12 also moves in conjunction with it. Then, when pulled out to a predetermined position, the engagement is released by the release means 17.

  Details of the engaging member, the engaged member, and the releasing means will be described later. Details of the mechanism and operation of engaging the outer drawer 11 and the inner drawer 12 will also be described later.

  The container 10 is capable of pulling out the outer drawer 11 and the inner drawer 12 by a work top 20, vertical partition plates 21 a and 21 b extending vertically downward from the work top 20, a back plate 22, and an intermediate partition plate 23. A storage space for storage is formed. Further, a pin 24 which is a part of the engagement releasing means 17 is provided on the inner side surfaces of the vertical partition plates 21 a and 21 b of the container 10. The detailed function of the pin 24 will be described later.

  The drawer structure 1 has a symmetrical configuration with respect to the cross section shown in FIG. Therefore, the structures of the engaging members 15a and 15b engaged members 16a and 16b, the releasing means 17 and the like will be described mainly on the vertical partition plate 21a side (right side in FIG. 2).

  The outer drawer 11 is installed below the housing space formed by the housing body 10, and has a short front door 30 positioned on the opening side (left side in FIG. 1) of the housing body 10, and the front door 30 extends from the housing 10. A short bottom plate 31 and side plates 32a and 32b (not shown) extending to the back plate 22 side (right side in FIG. 1), and a receiving side (right side in FIG. 1) of the bottom plate 31 and side plates 32a and 32b (not shown). A short-shaped back plate 33 connected to the end portion and facing the front door 30 is formed into a box shape having an upper surface side as an opening. The outer drawer 11 includes a receiving rail (not shown) and an inner rail (not shown) installed below the side plates 32a and 32b (not shown), and a predetermined direction (left direction in FIG. 1) as a drawing direction and its It is configured to be movable in the opposite direction.

  As described above, the engaging member 15a is provided on one of the both ends of the width direction (horizontal direction orthogonal to the predetermined direction) of the outer drawer 11 on the accommodation side of the back plate 33. ing. The engagement member 15a is a short fixed plate 34 attached to the back plate 33 with screws (not shown), and a side view (see FIG. 5) attached to the upper end of the fixed plate 34 through a shaft 38 so as to be swingable. 3) U-shaped and front-viewed (direction shown in FIG. 2) J-shaped lever 35, and a tension spring 41 that restricts swinging of lever 35 by its urging force.

  The range of swinging of the lever 35 is regulated by the rising portion 39 and the rising portion 40 provided on the fixed plate 34. Here, the state where the lower portion of the lever 35 is in contact with the rising portion 39 as shown in FIG. 3 is engaged in the first position of the engaging member 15a, and the state where the upper portion is in contact with the rising portion 40 is engaged. It is defined as the second position of the member 15a.

  Each of the fixed plate 34 and the lever 35 is provided with a spring hook 42 and a spring hook 43 extending in a direction away from the side plate 32a. Here, a tension spring 41 is stretched over to limit the swing of the lever 35.

  Specifically, in the first position of the lever 35 shown in FIG. 3, the tension spring 41 is configured to be located on the left side of the paper surface of the shaft 38 that is the center of swinging. Therefore, the lever 35 is urged in the counterclockwise direction indicated by the two-dot chain arrow in FIG. On the other hand, as will be described later, when the lever 35 is in the second position in FIG. 3, the tension spring 41 is configured to be positioned on the right side of the paper surface of the shaft 38. For this reason, the lever 35 is urged clockwise. That is, the engaging member is urged in the opposite direction to the second position by the pulling spring 41 serving as the urging means, and is in the first position when in the second position. It has the structure biased in the opposite direction. As described above, since the tension spring 41 always urges the lever 35 around the shaft 38, the position of the engaging member 15a does not change carelessly. For this reason, the use state (engagement state of the engaging member 15a and the engaged member 16a) of the drawer | drawing-out structure 1 is stabilized. Further, the drawer structure 1 is easy to use because the biasing force of the biasing means can be set according to the pulling resistance by replacing the pulling spring 41.

  A part of the release means described above is attached to the lever 35 via the shaft 38 on the side plate 32a side. The release means 17 includes the pin 24 described above, a striker base 45 fixed to the lever 35 with a screw (not shown), and a striker 47 attached to the striker base 45 via a shaft 46 so as to be swingable. The striker 47 functions as means for releasing the engagement between the engaging member 15a and the engaged member 16a by contacting the pin 24 when the outer drawer 11 is pulled out and tilting. Details of the disengagement mechanism will be described later.

  Note that the swing of the striker 47 is restricted by the rising portion 48 provided on the striker base 45 in the clockwise direction around the shaft 46 in FIG. On the other hand, a torsion spring (not shown) built in the shaft 46 can oscillate the striker 47 in the clockwise direction in FIG. 4 to be able to swing counterclockwise, but always returns to the position in FIG. Is configured to do. Therefore, the striker 47 can swing within the range of the solid line arrow shown in FIG.

  The pin 24 is set to a size and a position so as to contact only the striker 47 at the time of pulling out and housing.

  The inner drawer 12 is installed above the accommodation space formed by the container 10, and extends from the front plate 50 to the back plate 22 side of the container 10. A short-shaped bottom plate 51 and side plates 52a and 52b (not shown) and a short-shaped back plate 53 connected to the accommodation side end of the bottom plate 51 and side plates 52a and 52b (not shown) and facing the front plate 50. Are formed in a box shape having an upper surface side as an opening. As with the outer drawer 11, the inner drawer 12 has a predetermined direction (see FIG. 5) which is a drawing direction by a receiving rail (not shown) and an inner rail (not shown) installed below the side plates 52a and 52b (not shown). 1 (to the left of 1) and the opposite direction.

  And as mentioned above, the engaged member 16a is installed on one side of the lower side of the bottom plate 51 of the inner drawer 12 in the width direction (horizontal direction orthogonal to the predetermined direction). Yes. The engaged member 16a is attached to the bottom plate 51 with a screw (not shown), a short fixed plate 54 having a triangular shape in a side view and an inverted U shape in a front view, and an engagement rod fixed at a lower end of the fixed plate 54. 55.

  The engaging rod 55 is positioned in the U-shaped groove 36 of the lever 35 in the first position, whereby the engaging member 15a and the engaged member 16a are engaged.

  Next, the drawing operation from the housed state of the outer drawer and the inner drawer, and the operation of the engaging member, the engaged member, etc. associated therewith will be described.

  6 is a cross-sectional view showing a step of the drawing operation of the drawer structure shown in FIG. 1, FIG. 7 is a diagram showing a change state of the release means corresponding to the drawing operation shown in FIG. 6, and FIG. It is a figure which shows the change state of the engaging member and to-be-engaged member corresponding to the drawer | drawing-out operation | movement shown in FIG. 6, (1)-(3) of each figure has a correspondence. In FIG. 8, the description of members appearing in FIG. 7 is omitted for easy understanding of the drawing.

  When the front door of the outer drawer is gripped from the storage state shown in FIG. 1 and slightly pulled out in a predetermined direction, the state shown in (1) of FIG. 6 is obtained.

  First, referring to (1) of FIG. 6, (1) of FIG. 7, and (1) of FIG. 8, the engaging member is in the first position and the outer drawer 11 and the inner drawer 12 are in the engaged state. Shows a state of being pulled out in a predetermined direction in conjunction with each other. Further, the pin 24 and the striker 47 are in contact with each other soon. As shown in FIG. 8, a force in a predetermined direction indicated by a white-painted arrow acts on the outer drawer 11, and a force in the same direction that is equal to this force is applied from the U-shaped groove of the lever 35 to the engagement rod 55, and the inner drawer 12 is pushed forward. When the inner drawer 12 is interlocked, the lever 35 receives a slight force in the direction opposite to the predetermined direction indicated by the black arrow from the engagement rod 55 and is urged clockwise about the shaft 38. The However, the lever 35 in the first position is always urged by the pulling spring 41 in the counterclockwise direction with a force larger than that as described above, so that it does not swing to the second position. Absent.

  If the outside drawer is further pulled out from this state, the state shown in FIG.

  Next, referring to (2) in FIG. 6, (2) in FIG. 7, and (2) in FIG. 8, when the striker 47 comes into contact with the pin 24, the striker 47 moves against the biasing force of the pulling spring 41. 35 shows a state in which the engaging member 15a is in the middle of shifting to the second position from the first position. Specifically, in this state, the striker 47 is moving in a predetermined direction. On the other hand, since the pin 24 is installed in the container 10, the striker 47 is relatively pushed in the direction opposite to the predetermined direction indicated by the black arrow. For this reason, the striker 47 is urged clockwise about the shaft 38 as indicated by the solid line arrow. In this state, the striker 47 is in contact with the rising portion 48. Therefore, the striker base 45 to which the striker 47 is attached tilts. Furthermore, the lever 35 fixed integrally by the striker base 45 and a screw (not shown) is also tilted in conjunction.

  If the outside drawer is further pulled out from this state, the state shown in FIG.

  Next, referring to (3) in FIG. 6, (3) in FIG. 7, and (3) in FIG. 8, the engaging member 15a of the outer drawer is completely in the second position, and the lever 35 and the engaging rod The state where the engagement of 55 is released is shown. In this state, since the engagement between the engagement member 15a and the engaged member 16a is released, only the outer drawer 11 is pulled out, and the inner drawer 12 is not interlocked and stops at that position. Further, the inner drawer 12 can be pulled out from this state.

  Thus, the drawer structure 1 has a structure in which the engagement between the lever 35 and the engagement rod 55 is released when the outer drawer 11 is pulled beyond a predetermined position. For this reason, the linkage with the inner drawer 12 is released at a predetermined position of the outer drawer 11, and when the outer drawer 11 is further pulled out, the inner drawer 12 is more external than the conventional drawer structure shown in FIG. The degree of closing the opening on the upper surface of the drawer 11 is reduced. Therefore, it becomes easy to take out an object in the outer drawer 11 and store it in the outer drawer 11, thereby improving usability.

  Further, since the engagement can be released by installing the pin 24 at a predetermined position, the usability is improved.

  Next, the accommodating operation from the pulled-out state of the outer drawer and the inner drawer and the operation of the engaging member, the engaged member, and the like associated therewith will be described.

  9 is a cross-sectional view showing a process of accommodating the drawer structure shown in FIG. 1, and FIG. 10 is a diagram showing a change state of the engaging member and the engaged member corresponding to the drawing operation shown in FIG. FIG. 11 is a diagram showing a change state of the release means corresponding to the pulling-out operation shown in FIG. 9, and (1) to (3) in each figure are in a correspondence relationship. In FIG. 10, the description of members appearing in FIG. 11 is omitted to facilitate understanding of the drawing.

  First, from the state shown in FIG. 6 (3), the outer drawer is pulled out in the predetermined direction to the limit, and the state where the inner drawer is slightly pulled out is defined as the pulled-out state. When the front door of the outer drawer is gripped from this pulled out state and moved in the direction opposite to the predetermined direction, the state shown in (1) of FIG. 9 is obtained.

  Next, referring to (1) in FIG. 9, (1) in FIG. 10, and (1) in FIG. 11, the lever 35 comes into contact with the engagement rod 55 and is slightly inclined, and the engagement member 15a is in the second position. The state in the middle of moving to the 1st position from the position of is shown. That is, it is a state in the middle of shifting to the engaged state. When the outer drawer 11 is moved in a direction opposite to a predetermined direction indicated by a white arrow, and the lever 35 and the engagement rod 55 are brought into contact with each other, a shock is applied to the lever 35 from the engagement rod 55 to the lever 35 by a black arrow. A force in a predetermined direction shown acts. For this reason, the lever 35 is urged counterclockwise about the shaft 38, and the engaging member 15a moves from the second position to the first position. The striker 47 and the striker base 45 are also tilted in conjunction with this.

  As described above, when the outer drawer 11 is moved in the direction of the inner drawer 12, the lever 35 and the engagement rod 55 are engaged with each other, so that the outer drawer 11 and the inner drawer 12 can be easily returned to the interlocked state.

  If the outer drawer is further moved in the direction opposite to the predetermined direction from this state, the state shown in (2) of FIG. 9 is obtained.

  Next, referring to (2) of FIG. 9, (2) of FIG. 10, and (2) of FIG. 11, the lever 35 in which the engaging member 15a is in the first position is engaged with the engaging rod 55. The outer drawer 11 and the inner drawer 12 move in conjunction with each other. Moreover, the state where the striker 47 and the pin 24 come into contact soon is shown.

  If the outer drawer is further moved in the direction opposite to the predetermined direction from this state, the state shown in (3) of FIG. 9 is obtained.

  Next, referring to (3) in FIG. 9, (3) in FIG. 10, and (3) in FIG. 11, the striker 47 is brought into contact with the pin 24 to move in a predetermined direction indicated by a black arrow. Power is acting. The striker 47 is biased in the counterclockwise direction indicated by the center solid line arrow with respect to the shaft 46 and is in a tilted state.

  Thus, by configuring the striker 47 to swing, the presence of the pin 24 does not hinder the housing of the outer drawer 11 (the passage of the pin 24 of the engaging member 15a). Therefore, the housing operation of the outer drawer 11 is stable regardless of the state of the lever 35.

  From this state, when the outer drawer 11 is further moved in the direction opposite to the predetermined direction and the pin 24 is passed, the striker 47 is urged clockwise by a torsion spring (not shown) built in the shaft 46, and again, Contact the riser 48. Further, when the outer drawer is moved in the direction opposite to the predetermined direction, the accommodated state shown in FIG. 1 is obtained.

  9 (1), when the impact of the engaging member 15a upon contact with the engaged member 16a is weak, the lever 35 does not engage the engaging rod 55, and the engaging member 15a. However, the inner drawer 12 may be pushed forward while maintaining the second position. In such a case, the inner drawer 12 first reaches the back plate 22 of the container 10 and stops. Then, when the lever 35 of the outer drawer 11 is pushed into the engaging member 15a, the engaging member 15a shifts from the second position to the first position and is engaged with the engaged member 16a. As a result, FIG. It becomes the accommodation state.

  Further, the outer drawer has a pull spring built in a rail (not shown). The pulling spring is configured so that the outer drawer and the inner drawer are completely accommodated automatically by extending a predetermined amount at the time of withdrawal and contracting at the time of accommodation. Incidentally, since the inner drawer is accommodated in conjunction with the accommodation of the outer drawer, in this embodiment, a tension spring is incorporated only in the outer drawer. Here, if a pull spring is incorporated in both the outer drawer and the inner drawer, the force required for the extraction becomes heavy and the usability becomes inconvenient. Therefore, providing a pulling spring only on the outer drawer improves the usability and improves usability, and is advantageous in terms of cost.

  Furthermore, the inner drawer has a damper built in a rail (not shown) to mitigate the impact during housing. In the accommodated state, the inner drawer is configured so that it always comes closer to the back plate of the container before the outer drawer, so there is no need to incorporate a damper in the outer drawer, so the overall damper force is reduced.
