Since the wheels 32 are provided for the purpose of traveling on the track of the upper frame, it is sufficient that the wheels 32 are provided as many as the number of tracks of the upper frame.

The dimension L1 of the wheel stand 34 will be described later. The lower mounting part 40 of FIG. 5B is composed of a lower base 44 fixed to the lower end of the vertical frame of the door, a fixing member 46 for fixing to the door, and a cylindrical protrusion 42.
The cylindrical protrusion 42 is provided for the purpose of making the door slidable or rotatable along the guide groove of the lower frame. Therefore, this cylindrical protrusion 42 has a protrusion on the lower base 4.
As long as it is rotatable about a vertical axis with respect to 4, it is not necessarily required to be a cylinder, but may be a prism.

Next, the structures of the upper stop member and the lower stop member according to the present invention will be described with reference to FIG.

In FIG. 6, (a) is the upper stop member 50, and (b) is the lower stop member 60. Here, FIG.
The upper stop member 50 of (a) is roughly divided into a base 52 fixed to the upper frame 12 and a fixing member 59 for fixing the upper mounting component 30. Regarding the base 52, the back surface 52a side is used by being fixed to the inside of the upper frame. The clearance 57 provided in the base 52 is a space for fitting the wheel base 34 of the upper mounting component 30. The fixing member 59 is used to fix the wheel base 34 after fitting the wheel base 34 into the gap 57. Screw 5 provided on the fixing member 59
6 is used to fix the wheel base 34. Here, the two grooves 59a provided in the fixing member 59 are
This is for accommodating the rising portion formed on the track 12a. The upper stop member 50 is used to fix the upper mounting component 30 by the above-mentioned method as needed, and is attachable to and detachable from the upper frame 12.

On the other hand, FIG. 6B shows a lower stop member 60, the back surface 62 side of which is fixed inside the lower frame 14. Here, the cylindrical hole 64 provided in the central portion is provided for inserting the cylindrical protrusion 42 of the lower mounting component 40 described above. Therefore, the hole shape of the cylindrical hole 64 is the same as the lower mounting part 40.
If it is a shape that complements the cylindrical protrusion 42, it does not necessarily have to be a cylindrical shape, and may be a prism. Like the upper stop member 50, the lower stop member 60 is also used to fix the lower mounting component 40 as needed, and is attachable to and detachable from the lower frame 14.

Next, the principle of operation in which the door is slid / rotatably supported by the above-described upper mounting member 30, lower mounting member 40, upper stopper member 50, and lower stopper member 60 will be described. Upper fitting 30A, lower fitting 40
The same applies when A is used.

First, the principle of sliding and opening the door will be described with reference to FIGS. 7 and 10. FIG. 7 is a view of FIG. 5 viewed from the direction of the axis X, where (a) of FIG. 7 is the upper mounting part 30 and (b) is the lower mounting part 40. Figure 10
FIG. 9 is a cross-sectional view of FIG. 7 taken along a horizontal plane including the axis Y and the axis X of FIG. 5.

In the upper mounting part 30 of FIG. 7A, 38 is an upper base, 39 is a fixing member for fixing to the door, 34 is a wheel stand, 32 is a wheel, and 36 is a shaft support. Reference numeral 12 denotes an upper frame having a track 12a. When the wheels 32 travel on the track 12a provided in the upper frame 12, the vertical frame connected to the fixing member 39, and thus the door, moves. The cross-sectional view of FIG. 10A is a diagram showing this state more easily. That is, the pair of wheels 32 mounted on the wheel base 34 travels on the pair of tracks 12 a provided in the upper frame 12. The track 12a and the wheel 32 do not necessarily have to be a pair, and both the track 12a and the wheel 32 are 1
Although the same operation can be performed with only one wheel, it is desirable that both wheels have a pair from the viewpoint of running stability of the wheels 32.

On the other hand, the lower mounting part 40 shown in FIG.
In the figure, 44 is a lower base, 46 is a fixing member, and 42 is a cylindrical protrusion. Reference numeral 14 denotes a lower frame having a guide groove 14a.

The method of fixing the upper attachment 30 to one corner of the door is as follows. That is, the wheel base 34 is attached to the base 5 of the upper stop member 50.
After being fitted in the gap 57 between the 2 and the fixing member 59, the fixing member 59 is fitted and fixed with the screw 56 or the like. At this time, the upper mounting component 30 is rotatable about the axis M.

FIG. 8 (b) is a view showing a state in which the lower mounting member 40 is held by the lower stopper member 60 so as not to move. The lower stop member 60 is detachably attached so that the back surface 62 of the member is inside the lower frame 14. The connection between the lower mounting component 40 and the lower stopper member 60 can be easily realized by inserting the columnar protrusion 42 into the columnar hole 64. As a result, the lower mounting component 40 becomes rotatable about the axis M.

According to the principle described above, if the upper and lower mounting parts are arranged and fixed at the position where the rotation axis of the door and the rotation axis of the upper mounting part 30 and the vertical axis of the cylindrical protrusion of the lower mounting part 40 coincide with each other. , The door can be opened / closed by rotating around this axis.

Next, a method for mounting the upper mounting component 30 of the present invention on the upper frame 12 will be described with reference to FIG.
FIG. 11 is a diagram in which the wheel base 34 of the upper mounting component 30 is rotated 90 degrees in the direction of the rotation axis of the door (axis Y of FIG. 5) from the state of FIG. 10A. That is, the upper mounting part 3
By setting 0 as shown in FIG. 11 and inserting it into the upper frame 12, then as shown in FIG. 10, the wheels 32 can be easily placed on the pair of tracks 12a. The wheel base 34 may be fitted in the gap 57 between the base 52 of the upper stop member 50 and the fixing member 59 in the same manner. At this time, as can be seen from FIG. 11, the dimension L1 of the wheel base 34 is It is necessary to be designed to be smaller than the distance L4 between the pair of tracks 12a.

In order to attach the lower mounting component 40 to the lower frame 14, the door is lifted up so that the cylindrical protrusion 42 of the lower mounting component 40 fits into the guide groove 14a of the lower frame 14. Good. This is because, as described above, the door itself is supported by the wheels 32 that mainly run in the upper frame 12 and is in a suspended state. At this time, as can be seen from FIG. 7, the distance L2 between the upper part of the wheel stand 34 and the upper surface inside the upper frame 12 is designed to be longer than the distance L3 from the lower end of the cylindrical protrusion 42 to the upper end of the lower frame 14. It is necessary.
In addition, the lower mounting component 40 is attached to the cylindrical hole 64 of the lower stopper 60.
The same can be done when plugging in.
