As described in Patent Document 1, the slide rail can be pulled out to a fixed rail fixed to the cabinet, an intermediate rail that can be pulled out to the fixed rail, and an intermediate rail. Generally, it is composed of a plurality of rails such as a support rail fixed to the main body, and the structure of the slide rail is complicated.

  As an alternative to the support of the main body by such a slide rail, the step and storage described in Patent Document 2 has been proposed. In the step and storage described in Patent Document 2, a recess extending in the left-right direction is formed in the lower part of the back of the main body, and casters are fixed to the left and right ends of the recess so as to slightly protrude backward from the back of the main body. Has been.

The step and storage described in Patent Document 2 does not support the main body by the slide rail, so the structure is simplified accordingly, but when pulling out, the front of the main body is lifted and tilted downward to the back, The bottom of the main unit must be separated from the floor and the casters must be in contact with the floor. Lifting the main body in the state in which the article is stored is a burden on the operator even if it is in the front, and due to this, it is pulled straight out from the cabinet or pulled out backward. It is often impossible to perform a stable operation.

A lock mechanism is provided so as to be disposed above, and a simple mechanism composed of a lock bar 14 and a stopper 15 is employed as the lock mechanism.

  FIGS. 6 <a>, <b>, and <c> are respectively a front view, a plan view, and a cross-sectional view taken along line AA in FIG.

  The lock bar 14 has a descending surface 16 inclined obliquely downward from the front to the rear at the lower end, and two notches 17a and 17b that are slightly inclined obliquely forward and juxtaposed forward and backward at the lower part of the rear end. Have. The notches 17a and 17b are both formed upward from the lower end of the rear end of the lock bar 14. A protective cap 18 having a shape substantially coinciding with the outer shape of the lock bar 14 is attached to the lock bar 14 from the front to the front end of the notch 17a located at the front.

  Such a lock bar 14 is rotatably disposed on the fixed plate 19 by a connecting pin 20 at the rear end. As shown in FIGS. 1 and 4, the fixing plate 19 is fixed to the side plate 5 by a fastener such as a screw at the rear end portion of the main body 2 of the step platform / storage 1. The fixed position is a different position that does not interfere with the first guide member 100 and is below the first guide member 100. In this way, the lock bar 14 is disposed in the step platform / storage 1 so as to be rotatable up and down on the outer side of the rear end portion of the main body 2. As shown in FIG. 2, the lock bars 14 are respectively disposed on the left and right side plates 5 of the main body 2. Then, as shown in FIGS. 6 <a> and <b>, a connecting piece 21 is provided on the lock bar 14 at the upper end portion just behind the protective cap 18 so as to protrude toward the fixing plate 19 side. As shown, the two lock bars 14 respectively disposed on the left and right side plates 5 of the main body 2 are connected to each other by a connecting bar 22 that is fixed to the connecting piece 21 by a fixing tool such as a screw. As shown in FIGS. 1 and 4, the main body 2 is connected to the main body 2 so as to realize the connection of the lock bar 14 by bridging the connection bar 22 and to allow the lock bar 14 to turn up and down. In addition, a slightly larger opening 23 is formed in a circular shape at the upper rear ends of the left and right side plates 5. The opening 23 is arranged behind the back plate 4 so as not to obstruct the take-out and storage of articles from the storage space of the main body 2 when the connecting bar 22 is arranged. The opening 23 may be rectangular.

  The stopper 15 is disposed inside the storage portion 12 of the cabinet 8. Specifically, as shown in FIG. 5, the stopper 15 has a dowel shape, and is disposed on the inner side surfaces of the left and right side plates 24 of the cabinet 8 and protrudes inwardly in the storage portion 12. . As shown in FIG. 1, the stopper 15 is disposed at a position that corresponds to the pull-out position of the platform / storage 1 and can be fitted into the notches 17 a and 17 b of the lock bar 14. Further, the position of the stopper 15 is a different position that does not interfere with the second guide member 200, and is slightly above the second guide member 200.

  The lock mechanism including the lock bar 14 and the stopper 15 operates as shown in FIGS. 7 <a> <b> <c>.

  As shown in FIG. 7 <a>, when the step platform / storage 1 is stored in the storage portion 12 of the cabinet 8, they are located apart from each other, and this state corresponds to the time when the lock mechanism is not operated. The cum storage 1 can be moved back and forth freely. The lock bar 14 is held so that its front end does not tilt forward from the stopper 15 due to its own weight. For example, the front end portion of the lock bar 14 can be held by applying an elastic force by an elastic body such as a spring.

  When the step platform / storage 1 is pulled out, the lock bar 14 approaches the stopper 15, and as shown in FIG. 7 <b>, the stopper 15 comes into contact with the downward surface 16 on the front end side of the lock bar 14. As the storage 1 is pulled out, the lock bar 14 is pushed up with the connecting pin 20 as the center of rotation.

  As shown in FIG. 7 <c>, the stopper 15 is positioned below one of the front and rear cutouts 17a and 17b at the lower portion of the lock bar 14 at the drawer position of the step platform / storage 1 so that the lock bar 14 rotates downward by its own weight, and for example, the stopper 15 is fitted into the notch 17a. This state is when the lock mechanism is activated, and the step platform / storage 1 is locked at the drawer position and held in the locked state. In the locked state, as shown in FIG. 1, even if the caster 7 is positioned on the floor surface 10, the caster 7 does not move back and forth and right and left, and is in an immobile state. Therefore, the step board 11 can be closed and the step board / storage 1 can be used as a step board.

  In this way, the step / storage 1 employs a simple locking mechanism including the lock bar 14 and the stopper 15, and even with a simple locking mechanism, the step / storage 1 can be reliably pulled out. And can be held in the locked state, and the locked state of the platform / storage 1 when used as a platform can be easily realized. Also, no manual operation is required for locking. The locking mechanism operates automatically.

  When the platform / storage 1 is stored in the storage section 12 of the cabinet 8 after being used as a platform, as shown in FIG. 2, the connection bar 22 is lifted upward, as shown in FIG. The lock bar 14 is rotated upward, and the stopper 15 is removed from the notch 17a. The lock is released. The step platform / storage 1 can be moved backward by pushing the front portion of the main body 2 backward, and can be stored in the storage portion 12 of the cabinet 8. Thus, since the two lock bars 14 arranged on the left and right side plates 5 of the main body 2 are connected by the connecting bar 22, the two lock bars 14 are not individually linked but simultaneously interlocked to release the lock. The lock can be easily released, and the connection bar 22 can be operated with one hand. When the left and right side plates 5 of the main body 2 and the left and right side plates 24 of the cabinet 8 are close to each other, the unlocking by the connecting bar 22 is particularly effective, and there is a risk of catching hands to release the lock. It is easy to operate for children and the elderly.

  Moreover, since the lock bar 14 has two notches 17a and 17b, the stopper 15 can be fitted into one of the notches 17a and 17b according to the pull-out length of the step platform / storage 1. The stopper 15 is preferentially fitted into the notch 17a located on the front side. However, if the stepper / storage 1 is to be pulled out further, the connection bar 22 is lifted upward, the lock is released, and then the stepping / storage 1 is further moved. The stopper 15 is fitted into the drawer 17 and the rear notch 17b, and the step platform / storage 1 is locked. The drawer position of the step platform / storage 1 can be adjusted, and the position adjustment can be easily performed. In the lock bar 14, the cutouts are not limited to two cutouts 17a and 17b, and can be appropriately increased according to the size of the main body 2.

  Note that the step / cum storage of the present invention can be provided with the lock bar only on either the left or right side of the main body depending on the size, etc. Retention can be realized. When unlocking, the lock bar must be operated directly, but the risk of pinching a hand during the unlocking operation can be eliminated by attaching a protective cap.
