Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a movable partition in which a partition panel is provided movably along a rail, and particularly relates to a lower structure of a partition panel equipped with a sliding door or a hinged door. This is an improved version of .

(Prior Art) Conventionally, in a movable partition using a partition panel having sliding doors, the lower guide rail of the sliding door is configured to be movable up and down with respect to the partition panel, for example, in Japanese Utility Model Application Publication No. 1987-191272. The ones shown in are known. This makes it easier to move the partition panel by raising the lower guide rail and separating it from the floor, and also makes it possible to fix the partition panel by pressing the rail against the floor when installing the partition panel. This is what I did.

However, in the conventional structure described above, the panel main body is formed into a gate shape, the vertical frames provided on both the left and right sides of the entrance are hollow, and the lower end openings of both vertical frames protrude from the upper surface of both ends of the lower guide rail. The lower guide rail is supported so that it can be raised and lowered by fitting the raised and lowered lifting members in a vertically slidable manner.Since the panel body is formed in a gate-shaped open section, the panel body It has low strength and is easily distorted. In addition, since the lower guide rail is guided only by the engagement of the lifting members at both ends with the lower end openings of the vertical frames, the strength of the guide section and the lower guide rail itself is considerably increased. It is necessary to make it a thing. Moreover, when raising and lowering the lower guide rail,
If the lower guide rail is even slightly inclined with respect to the horizontal plane, the sliding resistance at the fitting part between the lifting member and both vertical frames increases and it becomes impossible to raise and lower. However, it is necessary to raise and lower the lower guide rail in a horizontal state at all times, and the operation for raising and lowering it is very troublesome.

(Purpose of the invention) The present invention was made to solve such problems, and in a movable partition using a partition panel with a door, the strength of the panel body is increased and the structure is placed at the bottom of the door. To provide a movable partition which also exhibits a reinforcing effect on the lower frame to increase overall strength and allows the lower frame to be raised and lowered smoothly at all times.

(Structure of the invention) The present invention is a movable partition in which a partition panel is movable along a rail, in which an entrance is provided in the partition panel, a door is provided at the entrance, and a reinforcing frame and a movable lower frame are placed at the bottom of the partition panel. Both ends of the reinforcing frame are fixed to the lower ends of the vertical frames provided on both the left and right sides of the entrance, and the movable lower frame is fitted onto the reinforcing frame so that it can be raised and lowered. It is characterized in that both ends of the lower frame are connected to elevating means provided within both the vertical frames.

(Example) In the present invention, there are cases where a sliding door is provided for the partition panel, and a case where a swinging door is provided.
Examples for each case will be described below.

First, an example in which a sliding door is provided will be explained with reference to Figs. 1 to 8. Fig. 4 is an external front view showing the partition panel when it is being moved, and Fig. 5 is an external front view showing the state when it is installed. In the figure, reference numeral 1 denotes a rail of a movable partition, which is installed on the ceiling of a building.
Reference numeral 2 denotes a partition panel of a movable partition, which is movably suspended and supported on the rail 1 by a runner 2a provided at its upper end. The partition panel 2 is
A rectangular panel body with a closed cross section is formed by vertical frames 3 placed on both the left and right sides and reinforcing frames 4 and 5 placed between their upper and lower ends (see Figures 1 to 3). Reinforcement frame 6 in the middle part of the panel body
is constructed, and its upper part is closed by a surface plate 7, and an entrance/exit 8 is formed in its lower part. A guide rail 9 is provided at the upper part of the entrance 8, and a pair of sliding doors 11 are suspended and supported on the upper guide rail 9 via runners 10 so as to be openable and closable.

The movable lower frame 12 serves as a lower guide rail for the sliding door 11, as shown in FIG.
The inside is formed hollow by a, 12b, and 12c, a guide groove 13 is formed on the upper surface, and a sealing material 14 is provided on the lower surface. And this movable lower frame 1
2 is fitted onto a reinforcing frame 5 provided at the bottom of the panel body, and is movable up and down by a predetermined amount H. Note that both ends of the reinforcing frame 5 are fixed to the lower end of the vertical frame 3 via attachment fittings 15, as shown in FIG.

On the other hand, a guide frame 16 is provided at the bottom of the sliding door 11 so that it can be raised and lowered. The guide frame 16 is the sliding door 1
It is formed into a T-shape with a continuous uniform cross section over almost the entire length in the width direction of the sliding door 11, and is supported so that it can freely rise and fall by a predetermined lifting amount h with respect to a holding frame 17 provided at the lower end of the sliding door 11. There is. The above lifting amount h is the holding frame 1
It is adapted to be regulated by a stopper piece 18 provided at 7.

The vertical frames 3, 3 disposed on both sides of the entrance/exit 8 are hollow inside, as shown in FIGS. 6 to 8, and each has a lifting mechanism 19 provided therein. The lifting mechanism 19 includes an operating shaft 20 that rotates around a horizontal axis.
It consists of a pair of upper and lower lifting rods 21, and a case 22 incorporating a motion conversion mechanism that converts the rotational movement of the operating shaft 20 into vertical movement and transmitting it to the lifting rod 21,
The operating shaft 20 faces a hole 23 provided in the vertical frame 3, and the lower end of the lower lifting rod 21 is connected to both ends of the movable lower frame 12 via connecting fittings 24, 25. As the motion conversion mechanism, any mechanism may be used, such as one using a rotary plate and a link, or one using a bevel gear, a threaded cylinder, or a threaded rod.

Furthermore, as shown in FIG. 3, a holding frame 27 having an upwardly opening groove 26 is fixed to the upper end of the panel.
A movable upper frame 28 with a uniform cross section that extends almost the entire length in the width direction of the panel is fitted and supported in the groove 26 so as to be able to rise and fall freely, and the upper elevating lever 21 of the elevating mechanism 19 is connected to both ends of the movable upper frame 28. are doing. 29 is a sealing material that is connected to the movable upper frame 25. Also,
30 and 31 are sealing materials connected to the side of the panel, 3
Reference numeral 2 denotes a sealing material continuous to both ends of the movable lower frame 12.

In the above configuration, when moving the partition panel 2, as shown in FIGS. 1, 3 and 4, the movable lower frame 12 is moved upward and the floor surface F
The partition panel 2 is moved along the rail 1 with the movable upper frame 28 moved downward and separated from the rail 1. At this time, as the movable lower frame 12 rises, the guide frame 16 at the lower end of the sliding door 11 is pushed up and the holding frame 1
7, the movable lower frame 12 is raised to a position where it comes into contact with the holding frame 17, and there is a space between this movable lower frame 12 and the floor surface F corresponding to the lifting amount H of the movable lower frame 12. A size gap 33 is formed. Thereby, even if the floor surface F has some irregularities, the partition panel 2 can be smoothly moved without the lower end surface of the partition panel 2, that is, the lower surface of the movable lower frame 12 coming into contact with the floor surface F.

Next, after moving the partition panel 2 to a predetermined position, a rotary operating tool such as a handle is engaged with the operating shaft 20 and the coaxial shaft 20 is rotated. The upper and lower lift bars 21 are moved in the vertically protruding direction through the motion converting mechanism, the movable upper frame 28 is protruded upward, and its upper end sealing material 29 is pressed against the lower surface of the rail 1 etc. The lower frame 12 is moved downward and its lower surface is brought into pressure contact with the floor surface F, thereby fixing the partition panel 2 in a predetermined position.

In this way, the movable lower frame 12, which serves as the lower guide rail of the sliding door 11, is moved together with the partition panel 2, and at the installation location of the panel 2, the movable lower frame 12 is pushed down by the lifting mechanism 19, and the floor surface F By fixing it to , there is no need to provide a lower guide rail for the sliding door 11 on the floor F. Also,
As described above, the reinforcing frame 5 is fixed between the lower ends of the vertical frames 3 and 3 on the left and right sides of the entrance 8, and the movable lower frame 12 is fitted onto the reinforcing frame 5 so as to be movable up and down, so that the movable lower frame 12 can be moved smoothly. In addition, the reinforcing frame 5 can enhance the reinforcing effect of the lower part of the panel body, and when the panel is installed, the movable lower frame 12 is reinforced by the reinforcing frame 5, so that the entire partition panel 2 can be raised and lowered. Strength can be increased.

In addition, in the installed state of the partition panel 2, the lowering of the movable lower frame 12 causes a rise and fall of the movable lower frame 12 between the upper end of the movable lower frame 12 and the lower end of the sliding door 11, that is, the lower end of the holding frame 17. A gap 34 corresponding to H will be generated, but as the movable lower frame 12 descends, the guide frame 16 also descends, and the lower end of the guide frame 16 remains engaged with the guide groove 13 of the movable lower frame 12. This engagement prevents the lower part of the sliding door 11 from swinging, and allows the sliding door 11 to be opened and closed smoothly. In addition, since the guide frame 16 is formed to have a continuous uniform cross-sectional shape over almost the entire length in the width direction of the sliding door 11, the guide frame 16 creates a gap between the sliding door 11 and the movable lower frame 12. This will close the gap 34 and improve the sealing performance.

Next, an embodiment in which the partition panel 2 is provided with a hinged door will be described with reference to FIGS. 9 to 11. In this embodiment, the structure of the panel body is substantially the same as in the above embodiments, and therefore the following:
The same parts as in the above embodiment are given the same reference numerals and will be explained as necessary.

In this embodiment, a horizontal frame 9' is provided at the upper part of the entrance 8 provided in the partition panel 2, and a reinforcing frame 5 and a movable lower frame 12' similar to those described above are provided at the lower part.
A pair of hinged doors 11' are supported on vertical frames 3 on both left and right sides of the entrance 8 via hinges 10' so as to be openable and closable.
Note that the support and elevating means for the movable lower frame 12' are the same as in the above embodiment. Furthermore, a movable hem frame 1 is attached to the lower end of the hinged door 11' via a holding frame 17'.
6' is provided so that it can be freely raised and lowered, and the amount of raising and lowering of this movable hem frame 16' can be regulated by a stopper piece 18'.

With this configuration, when moving the partition panel 2, the movable lower frame 12' is moved upward by the lifting means 19, and this movement pushes up the movable hem frame 16' and stores it in the holding frame 17', and at the same time The frame 12' is spaced apart from the floor surface F by a large distance, thereby making it possible to easily move the partition panel 2. When installing the partition panel 2,
By lowering the movable lower frame 12' and bringing it into pressure contact with the floor F, the movable lower frame 12' and the partition panel 2 can be fixed. Furthermore, during this installation, the movable hem frame 16' protrudes downward from the holding frame 17', and due to this protrusion, the substantial gap 34' between the hinged door 11' and the movable lower frame 12' becomes smaller, which improves the appearance. It will be good. Also, this gap 3
4' allows the swinging door 11' to be opened and closed without any trouble, and also simplifies the sealing structure of the gap 34' when the swinging door 11' is closed, for example, the mounting structure of the sealing material 35, and improves the sealing performance. become.

By the way, in the above embodiment, the movable lower frame 1
The means for raising and lowering the movable lower frames 12 and 12' is not particularly limited, but as in the above embodiment, by raising and lowering both ends of the movable lower frames 12 and 12' using the raising and lowering racks 18, the floor surface F can be tilted. If the movable lower frame 1
The movable lower frames 12, 12' can be brought into close contact along the slope of the floor surface F by adjusting the amount of vertical elevation of the movable lower frames 2, 12'.

(Effects of the invention) As described above, the present invention arranges a movable lower frame and a reinforcing frame at the lower end of the partition panel, and fixes the reinforcing frames to the lower ends of the vertical frames on both the left and right sides of the doorway. can be configured to increase its strength,
Moreover, this reinforcing frame can also be used to reinforce the movable lower frame, and the overall strength can be greatly improved. In addition, the reinforcing frame prevents the movable lower frame from being distorted and provides a guiding action when the movable lower frame is raised and lowered, so that the movable lower frame can always be smoothly raised and lowered.
