Description

The present invention relates to a bidirectional drawer structure capable of pulling out a moving body such as a drawer body from the front side and the back side.

Conventionally, as the above-described two-way drawer structure, the drawer body has a storage box, a front front plate, a rear front plate, and two support rails for placing and pulling the storage box on both front plates. The two support rails in the horizontal direction to which the front side front plate is attached and the two support rails in the horizontal direction to which the rear side front plate are attached are vertically moved when the storage box is in the storage position. And a main support member provided at support positions on both front plate sides of the storage box body, the storage box body being supported by the upper and lower support rails, and one front plate When the main support member is removed from the support rail, the auxiliary support member provided on the rear side of the storage box is placed on the extracted support rail when the main support member is removed from the support rail. A pivot lever is pivotally supported at the end of the storage box, A structure in which the engagement pin is formed in the.
Then, the front plate on the front side is pulled out together with the support rail in the front direction, and when the rotation lever reaches a predetermined position, the front plate on the front side and the storage box body are engaged with the engaging pin of the storage box body. The connected state is established, and the storage box is pulled out with the movement of the front plate. Further, when the extracted storage box is stored, the engagement state between the engagement pin and the rotation lever is released, and the drawer body is maintained in the storage position. (For example, see Patent Document 1)

In this case, in a state where the front plate and the drawer main body are pulled out to one side, the front plate and the drawer main body drawn from the other side to the one side cannot be operated at all. That is, when the drawer main body is pulled out and forgetting to close it, it is necessary to turn to the side where the drawer main body is pulled out and store the drawer main body. (It will take a lot of trouble if it is used for a path box completely partitioned by a wall etc.)
Further, when the front plate moves by a predetermined distance, the rotation lever engages with the engaging pin, and the drawer main body is pulled out together with the front plate. Therefore, a time lag occurs in the initial operation of the front plate and the drawer main body. Since a gap is generated between the main bodies and the gap is exposed when the main body is pulled out, there is a problem that not only the design is not preferable, but also the depth dimension of the main body is limited.
Also, there is a difference between the pull-out force when only the front plate is pulled out and the pull-out force when both the pull-out body are pulled out, so the pull-out force changes during the pull-out in the initial operation, and a smooth pull-out feeling is obtained. There was also a problem that it was not possible.

In addition, the support rails are arranged so as to overlap each other, and when the drawer body is pulled out together with the upper support rail, the main support member placed on the lower support rail is positioned below the upper support rail. Therefore, when the drawer body is lifted, the main support member comes into contact with the upper support rail, so that the drawer body cannot be removed and attached easily.
Furthermore, in the above structure, a rotating lever, an engaging pin, a main support member, and a fortune support member are required in addition to the support rail, and the number of parts is complicated and the structure is complicated. There was also a problem that it took time.

It is composed of a rail connecting plate to be moved and a second sliding restricting means for sliding the sliding side rail by an amount twice the sliding amount of the rail connecting plate, and a moving body is attached to the sliding side rail. Therefore, even if there is forgetting to close, when the front plate on the opposite side is pulled out, the front plate on the other side and the moving body slide at a ratio of 1 to 2, Specifically, since the front plate on the pulled-out side and the moving body are completely pulled out, the front plate on the side that has been forgotten to be closed can be closed, which is very convenient to use.

In addition, the sliding side rail to which the moving body is attached slides at a ratio of 2 to 1 in the same direction as the rail connecting plate, and the rail connecting plate is connected to the front side front plate and the rear side front plate. Since the first and second rails also slide at a ratio of 1: 2 in the same direction as the rail connecting plate with one of them stopped, there is no time lag in sliding between the moving body and the front plate. No extra gap is generated between the face plate and the moving body, and the depth dimension of the moving body (drawer body) is not limited.
Further, when the front plate is pulled out, the moving body slides at the same time, so the pulling output (sliding force) is always constant, and there is no sense of incongruity during the pulling operation, and a smooth pulling operation can always be obtained.

.. Are formed at the sliding direction side ends of the lower cover body 743 and the upper cover body 747, and a predetermined position (second pinion member) of the slide rail mounting substrate 43 of the rail connection plate 4 is formed. 74), the lower cover body 743 and the upper cover body 747 hold the second pinion 741 rotatably inside the second pinion member attachment cutout hole 44). The second pinion 741 is protruded in the vertical direction of the sliding rail mounting substrate 43 with the sliding side end portion of the pinion member mounting notch hole 44 being sandwiched, and is connected by a connecting screw.

The first embodiment is configured as described above, and both the front-side front plate 10 and the rear-side front plate 20 are fixed to the fixed-side main body 100 with the latch members 105. State), the latch member 105 is operated by the pulling portion 106 of either one (for example, the front side front plate 10), the fixed state with the fixed side main body 100 is released, and the front side front plate 10 is moved to the front side. When this is done (when pulled out), the first outer member 13 of the first rail 1 connected to the front side front plate 10 is also pulled out together. Then, by pulling out the first outer member 13 of the first rail 1, the first rack member mounting member 312 and the first rack member 31 are also pulled out simultaneously.

Then, the first rack member 31 rotates the first pinion 341, but the second rack member 32 that meshes with the first pinion 341 is integrated with the second rack member mounting member 322 and the second outer member 23 on the back side. Since it is connected to the front plate 20 and the back side front plate 20 is fixed to the stationary side main body 100, the first pinion 341 (the first pinion member 34) rotates on the second rack member 32 and the front side front plate. In the pull-out direction of 10, the front side front plate 10 moves with a sliding amount that is half of the sliding amount.

That is, the movement of the first pinion member 34 in the pull-out direction causes the rail connection plate 4 and the second pinion member 74 held by the rail connection plate 4 together with the first inner member 16 and the second inner member 26 to be front side front. The face plate 10 is moved in the pulling direction.
Then, the second pinion 741 of the second pinion member 74 meshes with the third rack member 71 and the fourth rack member 72, and the third rack member 71 is the third rack mounting member 50 (fixed side outer member 53). Therefore, the second pinion 741 (second pinion member 74) moves in the pull-out direction of the front side front plate 10 while rotating.

When the second pinion 741 rotates and moves in the pull-out direction of the front side front plate 10, the fourth rack member 72 that meshes with the second pinion 741 has a combined amount of the rotation amount and the movement amount of the second pinion 741. The front-side front plate 10 is pulled out together with the fourth rack mounting member 60 (sliding side outer member 66) and the moving body (drawer main body) 600 with a moving amount twice that of the second pinion 741 (second pinion member 74). Move in the direction.
That is, since the front side front plate 10 and the moving body (drawer main body) 600 move simultaneously with the same movement amount, no time lag occurs, and therefore there is a gap between the front side front plate 10 and the moving body (drawer main body) 600. Does not occur.
When the front-side front plate 10 and the moving body (drawer main body) 600 that are pulled out are stored, they are stored in the reverse movement.
The same applies when the rear side front plate 20 is pulled out.

On the other hand, when the front side front plate 10 and the moving body (drawer main body) 600 are left in a state of being pulled out, the mobile body (drawer main body) 600 is stored or moved by operating from the back side. When the main body) 600 is pulled out to the back side, the latch member 105 is operated by the pulling portion 106 of the back side front plate 20 to release the fixed state with the fixed side main body 100, and the back side front plate 20 is moved to the back side. When moved (withdrawn), the second outer member 23 of the second rail 2 connected to the rear side front plate 20 is also pulled out together. And the 2nd rack member attaching material 322 and the 2nd rack member 32 are also pulled out simultaneously by the 2nd outer side member 23 of the 2nd rail 2 being pulled out.

Then, when the second rack member 32 is pulled out, the second rack member 32 tries to rotate the first pinion 341, but the first outer member 13 of the first rail 1 is in the most pulled out state. Therefore, the first rack member 31 that meshes with the first pinion 341 does not move in the front direction, and therefore the first pinion 341 does not rotate, and at the same time the second outer member 23 moves in the rear direction. The first pinion member 34, the first outer member 13 of the first rail 1, the front side front plate 10, and the rail connecting member 4 holding the first pinion member 34 also move in the back side direction with the same sliding amount.

When the rail connecting member 4 moves in the rear side direction, the second pinion 741 of the second pinion member 74 is engaged with the third rack member 71 and the fourth rack member 72, and the third rack member 71 is attached to the third rack. The second pinion 741 (second pinion member 74) moves in the pull-out direction of the rear side front plate 20 while rotating because it is fixed to the fixed side main body 100 via the member 50 (fixed side outer member 53). To do.

When the second pinion 741 rotates and moves in the pull-out direction of the rear side front plate 20, the fourth rack member 72 that meshes with the second pinion 741 has a sum of the amount of rotation of the second pinion 741 and the amount of movement, that is, The back side with the fourth rack mounting member 60 (sliding side outer member 66) and the moving body (drawer main body) 600 at a moving amount twice that of the second pinion 741 (second pinion member 74, rail connecting material 4). From the state where the moving body (drawer main body) 600 is located in the fixed-side main body 100 (the state shown in FIG. 11), the rear-side front plate 20 and the front-side front plate 10 are further moved. The moving body (drawer main body) 600 is also in contact with the back side front plate 20 and pulled out to the most back side, with the back side front plate 20 fully pulled out. at the same time Side front plate 10, the latch member 105 engages a portion of the fixed body 100, the front-side front plate 10 is a fixed state on the fixed side body 100.
That is, even if the moving body (drawer main body) 600 is forgotten to be closed on one side, the state that the mobile body (drawer body) 600 has been forgotten to be closed can be released by the operation from the other side (the moving body is returned to the retracted state). It is also possible to pull out the body (drawer body) 600 to the other side.
In the state where the rear side front plate 20 (front side front plate 10) is pulled out most, the movable body (drawer main body) 600 is on the rear side at a speed twice that of the rear side front plate 20 (front side front plate 10). Since it collides with the front plate 20, a shock absorber may be provided between the moving body (drawer body) 600 and the rear side and front side front plates 10 and 20 in order to reduce this impact.

Next, a second embodiment will be described with reference to FIG.
Reference numeral 100 denotes a fixed-side main body, and reference numeral 1 denotes the same first rail as in the first embodiment, which is located opposite to the left and right where the back surface of the front-side front plate and the front-side end are connected, and reference numeral 2 Is located opposite to the left and right where the back side and the back side end of the back side front plate 20 are connected, and is the same as the second rail of the first embodiment disposed back to back with the first rail 1. Reference numeral 3 denotes a rail, reference numeral 3 denotes a first sliding amount regulating means disposed between the first rail 1 and the second rail 2, and reference numeral 4 denotes one of the first rail 1 or the second rail 2 stopped. In a state where one of the front-side front plate or the rear-side front plate is fixed to the fixed-side main body by the latch member, the sliding amount of the other rails 1 and 2 is 2 by the first sliding amount regulating means 3. 1 shows a rail connecting plate that slides in the same direction. The reference numeral 6 indicates a pair of fixed-side rails connected to the left and right, and reference numeral 6 indicates a sliding-side rail that can be pulled out in either the front side or the rear side with respect to the fixed-side rail 5. A moving body (drawer main body) that slides together with the sliding side rail 6 is shown. Reference numeral 7 is disposed between the fixed side main body 100 and the sliding side rail 6 and is twice as much as the sliding amount of the rail connecting plate 4. The second sliding amount regulating means for sliding the sliding rail 6 in the same direction as the rail connecting plate 4 is shown.

That is, in the second embodiment, the first rail 1 and the second rail 2 are provided back to back, the rail connecting plate 4 is provided between the first inner member 16 and the second inner member 26, and the rail connecting plate 4 is upright. The fixed side rail and the sliding side rail of the first embodiment are arranged in the vertical direction, and the first sliding amount regulating means 3 of the second embodiment has the same structure as that of the second pinion member of the first embodiment. The second sliding amount regulating means 7 of the second embodiment is a structure in which the second pinion member of the first embodiment is disposed sideways as the second pinion member of the second embodiment. Therefore, even when the movable body (drawer main body) 600 is arranged in a plurality of stages in the vertical direction, the partition plate in the vertical direction corresponding to the bottom plate of the first embodiment is not required, so that the overall cost can be reduced.
Further, in the first embodiment, the arrangement of the first rails and the like is L-shaped as a whole, whereas in the second embodiment, it is I-shaped, so that the storage volume at the time of inventory can be reduced.
