DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
In the first embodiment, in the dam waiter having an upper door and a lower door that open or close the entrance / exit by separating or meeting each other in the vertical direction, when the entrance / exit is opened, the floor of the dam waiter's basket chamber and the entrance / exit frame The gap closing means has a gap closing means for closing a gap between the lower edge and the gap closing means between the floor of the damway cage room and the lower edge of the inlet / outlet frame when the inlet / outlet is opened. It has a passed width and is provided on the open end side of the lower door so as to swing between a vertical state and a horizontal state in this width direction.
Hereinafter, this will be described with reference to FIGS.
1 is a perspective view showing a state in which the inlet / outlet is closed, FIG. 2 is a perspective view showing a state in which the inlet / outlet is opened, and FIG. 3 is an explanation showing each operation stage of the gap closing means by (A) to (D). FIG. The same reference numerals as those in FIG. 4 indicate substantially the same contents.
[0009]
In FIG. 1, reference numeral 5 denotes an upper door, and reference numeral 6 denotes a lower door. The upper and lower doors 5, 6 open or close the entrance / exit 1 formed by the entrance / exit frame 3 while being separated from each other or met in the vertical direction.
In FIG. 2, when the entrance / exit 1 is opened, a gap closing means 7 is provided to close the gap 4 between the floor 21 of the damway cage chamber 2 and the lower edge 31 of the entrance / exit frame 3. .
The gap closing means 7 shown in the figure has a width spanned between the floor 21 of the damway basket chamber 2 and the lower edge 31 of the entrance / exit entrance frame 3 when the entrance / exit 1 is opened. It is a closing plate extending in the longitudinal direction.
The closing plate 7 is pivotably mounted on the open end side of the lower door 6 via a hinge 71 in this example so as to swing between a vertical state and a horizontal state in this width direction.
[0010]
3A to 3D, the operation of the closing plate 7 as the gap closing means will be described.
In FIG. 3 (A), the closing plate 7 is accommodated in the open end side of the upper door 5, that is, the lower end side, with the width direction being substantially vertical when the entrance / exit 1 is closed by the upper and lower doors 5 and 6. It has been.
In the illustrated example, the pivot door 71 is provided at the front edge of the open / close port 1 on the open end side, that is, the upper end side of the lower door 6, and the closing plate 7 in the vertical state is an extended surface on the front side of the lower door 6. It is positioned vertically so that it is positioned above. That is, the closing plate 7 is in a vertical state because one end in the width direction of the closing plate 7 is sandwiched between the back surface of the front member of the upper door 5 and the front side surface of the lower door 6.
In this case, the other end in the width direction of the closing plate 7 is stored together with the open end side portion of the lower door 6 in a storage portion 72 formed inside the lower end of the upper door 5. The storage portion 72 is provided with an opening 73 on the back side of the upper door 5 so that the closing plate 7 can swing and enter and leave the storage portion 72.
[0011]
3 (B) to 3 (D), the closing plate 7 is stored in the upper door 5 when the entrance / exit 1 is opened, that is, as the upper and lower doors 5 and 6 are separated from each other in the vertical direction. The restraint by the portion 7 is released, and finally the closing plate 7 itself becomes horizontal in its width direction by its own weight on the open end side of the lower door 6 due to the left and right imbalance of the pivoting portion 71. It rotates as follows.
As shown in FIG. 3C, the horizontal state of the closing plate 7 is supported on a flat surface on the open end side of the lower door 6, and the lower door 6 is lowered while maintaining this horizontal state. As shown in (D), when the entrance / exit 1 is opened, it is bridged between the floor 21 of the basket chamber 2 and the lower edge 31 of the entrance / exit frame 3.
In this way, the gap 4 between the floor 21 of the basket chamber 2 and the entrance / exit frame 3 is closed.
[0012]
In the first embodiment, when the entrance / exit 1 is closed, it is preferable to provide return drive means so that the closing plate 7 gradually returns to the original vertical state as the lower door 6 is raised (not shown). (Illustrated).
As the return drive means, for example, a push-up member that pushes up the closing plate 7 from below to bring the closing plate 7 into a vertical state is provided in the lower door 6 so as to be movable up and down, and the push-up is raised according to the rise of the lower door 6 A drive means for raising the member is provided.
[0013]
Embodiment 2. FIG.
The second embodiment is a dam waiter having a configuration of upper and lower doors 5 and 6 that do not require the storage portion 72 to be provided in the upper door 5 (not shown).
That is, in the first embodiment, the upper door 5 is provided with the storage portion 72, but when the rear side of the upper door 5 is different from the front side of the lower door 6, the upper door 5 Since the back side of the space is free space, there is no need to provide the storage portion 72.
[0014]
Embodiment 3 FIG.
The third embodiment is a dam waiter having a configuration in which a closing plate 7 as a gap closing means is accommodated in a thickness width of the floor 21 of the basket chamber 2 so as to be freely inserted and removed (not shown).
In the case of this configuration, when the entrance / exit 1 is opened, if necessary, the closing plate is manually pulled out so that the leading end side reaches the entrance / exit entrance frame 3 and is pushed in and stored in the floor 21. It will be.
In addition, it is not always necessary to store the closing plate in the floor 21. For example, the floor 21 itself may be drawn out as it is.
In any of the above cases, the closing plate can be automatically taken in and out by using an appropriate driving means, instead of manually removing and inserting the closing plate.
[0015]
【The invention's effect】
According to this invention, the gap between the floor of the basket chamber and the lower edge of the entrance / exit opening frame when the entrance / exit opening is opened, and the upper and lower doors that open or close the entrance / exit by separating or meeting each other in the vertical direction. in Damuweta having a closing plate and closing a closing plate has a width which is laid between the lower edge of the floor and out opening frame mosquito Gore chamber, the lower door to swing in the width direction When it is pivotally attached to the open end and the entrance / exit is closed by the upper and lower doors, it is sandwiched between the upper and lower doors and stored in a substantially vertical state, and the entrance / exit is opened. , it is possible to prevent the horizontal and such Runode by its own weight is released restraint by the upper door, when loading and unloading the article from the basket chamber, the fall of the article from the gap.
