Abstract

The invention relates to a movable partition, which is arranged on the ceiling and can move along the suspension rail, and can form any interval in the indoor area. Regardless of the position of the rolling device and the panel main body arranged in the above-mentioned suspension rail, they can rotate freely and move smoothly in the suspension rail, and through the upper and lower track wheels of the rolling device and the control device, the panel main body can be rotated freely. Branches, bends, etc. can be easily moved, and the main body of the plate is just vertically opposed to the fixed wall.

Description

The invention relates to a movable partition that can move along a guide rail erected on the ceiling and can isolate a large space into any space.

In large-scale exhibitions and banquet halls such as large department stores and hotels, there are large living rooms with large areas. When they must be set up as small-scale banquet halls or meeting rooms, mobile partitions can be used to divide the large space. separated into spaces of appropriate size. The mobile partition is composed of a suspension rail with a C-shaped cross section on the ceiling, and a freely movable partition body suspended on the suspension rail. The suspension rail groove is set downward in the above suspension rail. For the trolley-type sliding device, the sliding device is connected to the above-mentioned bulkhead body through suspension studs.

On the other hand, in order to adapt to various changes in the configuration of the main body of the partition, many branch roads are formed on the suspension rail, and the partition itself can move freely no matter which branch road it is on. For example, there is Japanese Patent Application Publication No. 54-12 81 44 that has thought of a way on the above-mentioned sliding device. There is also the Japanese Utility Model Announcement No. 52-55 25 1 for improving the main body of the board.

However, in recent years, mobile partitions have been required to have the same performance as fixed walls in terms of sound insulation and aesthetics. Therefore, the above partitions cannot meet the requirements of large size and heavy weight, and there are many specific problems as follows:

1. Due to the heavy load of the sliding device arranged in the guide rail, a large frictional resistance is generated between the sliding device and the sliding pad between the hanging rail, which hinders the smooth movement of the partition. Especially when the sliding device reaches the curved part or the bifurcation point of the suspension rail, the movement resistance of the sliding device becomes large, which hinders the movement of the partition.

2. As indicated in the above-mentioned utility model bulletin, in order to move the partition board at the branch point of the suspension rail, etc., a control device is provided on the main body of the partition board, and the above-mentioned rolling device can be connected with the board main body through the suspension stud. Due to the frictional resistance between the mobile connection and the main body of the plate, the control device cannot move freely, which hinders the free movement of the dividing plate on the contrary.

3. In addition, the main body of the panel must be in a vertical position with respect to the ground when forming the partition wall. However, due to the enlargement of the main body of the panel, it may be inclined.

4. Because the main body of the board is too large and heavy, difficulties arise in construction and maintenance. according to this Points, especially the assembly part of the above-mentioned rolling device and the control device and the repair of the control device are very difficult, and it is impossible to repair quickly when a failure occurs.

In view of the above various problems, the main purpose of the present invention is to provide a movable partition that can smoothly move anywhere such as branch roads and curved roads of suspension rails.

Specifically, its purpose is: (a) Reduce the frictional resistance of the sliding device as much as possible, so that it can move smoothly even when there are branch roads and curved roads in the suspension rail. (b) The movement of the control means relative to the panel body is possible with very little sliding frictional resistance, while the bulkhead body is correctly and vertically positioned. (c) The sliding device, the control device and the main body of the partition all have a structure that is easy to assemble and disassemble, and is easy to construct, repair and maintain.

Fig. 18 is an explanatory view showing the operation of the control device in Fig. 17 .

Fig. 1 shows the arrangement in the suspension rail, and the sliding device moving in the suspension rail. sliding device (hereinafter referred to as the slider) 10 is composed of main components such as the slider main body 11, the moving rollers 12,12, the lower track wheels 13,13 and the upper track wheels 14,14.

The slider main body 11 is formed into a slightly long rectangular shape. Its central part has a stepped through hole 11a that penetrates up and down, and a thrust bearing 11b and a slider body 11 are installed on the stepped portion of the through hole 11a. Through this thrust bearing 11b, the suspension stud 21 of the partition body Rotate freely and hang down. Therefore, the slider main body 11 and the suspension stud 21 can rotate smoothly due to the rolling friction of the bearing 11b.

The moving rollers 12, 12 (ie 3 pairs of 6 rollers) are installed on the left and right sides of the slider main body 11, through the shafts 11c, 11d (11d can rotate freely), and at the same time, the 6 rollers can contact on the same plane.

Bottom track wheel 13,13 is contained in the front and rear of slide block main body 11 below, and each wheel can rotate freely. The lower rail wheels 13, 13 are mounted on the center line CL in the front-rear direction of the slider body 11 through the studs 13a, 13a screwed on the lower surface of the slider body 11, and sandwich the suspension studs 21 on both sides.

The upper track wheels 14, 14 are rotatably mounted on the front and rear positions above the slider main body 11 through mounting studs 14a, 14a. It's just that the upper track wheels 14, 14 are not on the center line CL of the slider main body 11, but are offset on the side close to one side. The moving suspension rail 30 of slide block 10 is arranged as shown in Figure 2, and its section is a C-shaped rectangle, and the continuous opening 31 in the vertical direction of the suspension rail is arranged downward. The internal structure of this suspension wheel 30 is the left and right moving surfaces 32,32 that the left and right moving rollers 12,12 of the slide block 10 roll, and there are moving track surfaces 33,33 in its inner side. The lower track wheels 13, 13 rotate along the moving track surfaces 33, 33. Because the distance d between the set moving track surfaces 33, 33 is slightly larger than the diameter of the lower track wheel 13, thereby limiting the slide block 10 from left to right Direction shifting.

As shown in Figure 3, a bifurcation point S is set at the place where the suspension rail 30 is fixed, and a suspension rail 34 that can contact the upper track wheels 14, 14 is laid on the top near the bifurcation point S (see Fig. 2, Fig. 3. Figure 4). The suspension rail 34 has a gently curved rail surface 34a along the branched suspension rail 30 . The track surface 34a can determine the moving route of the slide block 10, that is, the upper track wheels 14, 14 of the slide block 10 roll along the suspension track surface 34a, so the whole slide block 10 also changes its own route along the suspension track 34 .

A set of movable partitions is composed of a plate main body 22, two suspension studs 21, 21 protrudingly arranged on its upper end surface 22a, and sliders 10, 21 supporting the two suspension studs 21, 21 respectively. 10 made up.

When the advancing direction of the moving partition is from the direction of _K1 in FIG. 2 to the left suspension track, the operator can push the partition 22, and the front slider 10 approaches the bifurcation point S in the direction of arrow _K1 . Since the distance d between the moving track surfaces 33, 33 of the suspension track 30 gradually increases at the bifurcation, the lower track wheels 13, 13 cannot determine the moving line of the slide block 10. To this end, the upper rail wheels 14 , 14 are bounded by rails 34 , while the entire slider 10 is guided. That is, as long as the upper track wheel 14 in the front is in contact with the track surface 34a of the track 34, its upper track wheel 14 will rotate to the arrow direction _K2 in Fig. 3 and will move along the track surface 34a simultaneously, and the front end of the slider 10 will Change direction to the left (see dotted line in Figure 3).

At this time, the sliding block 10 generates a rotational moment centered on the suspension stud 21 and caused by the centripetal force, which can easily change the advancing route of the sliding block 10 . In this way, when the advancing course of the slider 10 changes, the slider 10 makes relative rotation relative to the main body 22 of the bulkhead. However, since the main body 22 of the plate supports the slider 10 through the thrust bearing 11b, the relative rotation of the two , can slide by rolling friction.

Therefore, when the slider 10 passes the branch point S, the lower track wheels 13, 13 are guided by the moving track surfaces 33, 33 to move.

And when each slide block 10 was changing the route, the moving rollers 12,12 on one side obliquely crossed the opening between the moving rails 33,33 (seeing the dotted line in Fig. 3), and the three moving wheels on one side 12. There are at least two moving wheels 12 in 12 that can always be in contact with the moving surface 32, so even in this case, the slider 10 can maintain a horizontal position, and the slider 10 can smoothly pass through the bifurcation point S . But, under the very small situation of the distance d between moving track 33,33, moving roller 12,12 does not need 3 pairs of 6 wheels, as long as there are 2 pairs of 4 wheels, it can also be used without hindrance.

In Fig. 4, when the slider 10 changes course to the right relative to the arrow K ₄ direction, the track 34 curved to the right and the upper rail guide wheels 14, 14 that rotate right above the slider 10 can be joined together. In addition, if the track 34 can give the centripetal force to the right direction of the upper track wheel 14,14 in the direction perpendicular to the advancing direction, it is enough, so the upper track roller 14,14 on the left side above the slide block 10 is rotated ( See the two-dot dash line in Fig. 4), then join with the track 34 that is arranged on the left side, also can obtain same effect.

As shown in Figure 5, by selecting the heights of the track 34 as A ₁ and A ₂ , and the installation heights of the upper track wheels 14 and 14 as a ₁ and a ₂ , you can choose whether the two are engaged, that is, you can choose the slider There is no change in the forward route of 10. For example, for the track 34 of height A ₁ , it is engaged with the two upper track wheels 14, 14 of installation height a ₁ , a ₂ , so the two kinds of sliders 10, 10 with the upper track wheels 14, 14 The advancing route can be changed, and for the track 34 of height A, it does not engage with the upper track wheel 14 of installation height a ₁ , but only engages with the upper track wheel 14 of installation height a ₂ , therefore, only the latter upper The slide block 10 of track wheel 14 just can change advancing route.

Two front and rear end faces of the slide block 10, as shown in FIG. 6, can be loaded onto with two pads 15,15. Assuming that the effective thickness of the spacers 15 and 15 is n, the thickness of the plate main body 22 is t, and that the length in the front-back direction of the slider 10 exceeds m, m+2n>1. According to this formula, since the main bodies 22, 22 of the two plates are not in contact, breakage of the main bodies 22, 22 of the plates can be effectively prevented.

According to the above description, the upper track wheels are respectively installed on the front and rear of the slider, and Since the thrust bearing is arranged between the suspension stud, when the forward path of the slider is to be changed, an effective rotational moment that can change the direction of the slider will be generated. And the friction resistance between the slider and the suspension stud changes from sliding friction to rolling friction. Therefore, the movement resistance of the entire slider becomes smaller, and even if there is a heavy mobile partition, it can be easily changed. way forward. This device has such good effects.

7 and 8 show the control device 40 provided on the main body 22 of the panel. The control device 40 is provided with a bushing 44 , a main body member 41 , suspension rollers 42 , and track wheels 43 , 43 .

Sleeve pipe 44 is a cylindrical part (referring to Fig. 8) that a bottom has male screw thread 44b, forms threaded hole 44a on the inner peripheral surface of top.

The main body part 41 has a threaded hole 41a penetrating up and down through its central part, and the male thread 44b of the sleeve 44 is screwed into it. The main body part 41 is provided with a fixed shaft penetrating the left and right directions, and two pairs of four-wheeled suspension rollers 42 . . . are mounted on both ends. A part of the outer peripheral surface of the suspension roller 42 protrudes from the upper surface of the main body member 41 .

Above the main body part 41, track wheels 43, 43 are respectively housed before and after it. The track wheels 43, 43 clamp the sleeve pipe 44 and lean against the main body part 41 above. The track wheels 43 , 43 are located on the center line in the front-rear direction of the main body member 41 .

As shown in FIG. 1 , the suspension stud 21 screwed into the casing 44 can freely hang down from the slide block 10 through the thrust bearing.

The control device 40 is movable relative to the main body 22 of the panel and hangs downward. That is, the main body 22 of the plate surrounds corner-shaped frames 55, 55... on the four end faces of the plate-shaped core material, and a track member 52 of the same shape as it is fixed on the upper frame 55, and the two sides are attached to the surface. Material 54.

Near the end of the upper side of the track member 52, there is a long hole 53 centered on the longitudinal centerline of the track member 52, and the two sides of the long hole 53 form track contact surfaces 52a, 52a. Because the width D ₁ of setting slotted hole 53 is a little larger than the diameter D ₂ of track wheel 43, therefore can control the vibration of track wheel 43,43 on the track contact surface 52a, 52a in the left and right direction within a small range. But, in order to allow track wheel 43,43 along slotted hole 53, and rotate in slotted hole 53, thereby will determine the position of its height.

The rail contact surfaces 52a, 52a are supported downward by the suspension rollers 42, and the weight of the panel main body 22 can be distributed and pressed on the respective suspension rollers through the rail members 52. Moreover, the track wheels 43, 43 rotate along the elongated hole 53, so the control device 40 can move back and forth within the length of the elongated hole 53. Accordingly, the main body 22 of the panel can behave as in FIG. 9 .

Typically large mobile partitions are operated by two operators. Push the board main body 22 suspended downwards on the suspension rails H and H parallel to each other in the arrow directions J ₁ and J ₂ respectively. Due to the difference in the thrust of the operator, the board main body 22 is slightly different from the forward direction. Tilt (as shown in the double-dot dash line 22a in Figure 9). At this time, since the control device 40 can move freely within the rail member 52, the suspension stud 21B can easily change its position to 21B ₁ and change the distance from the other suspension studs 21A ₀ , 21A ₁ . Therefore, the panel main body 22 can move smoothly while appropriately changing its position as the operator pushes it.

This means that the main body 22 of the panel hanging down on a suitably curved suspension rail H is constantly rotated. For example, in Fig. 10, the plate main body 22 advancing in the direction of the right arrow J ₃ moves sequentially in the directions of the arrows J ₄ and J ₅ through the Y-shaped bifurcated suspension rail guide H, so that it moves in sequence relative to the wall surface. W can make a correct side-by-side movement (as shown in the double-dot dash line in Figure 10).

In addition, the movable range of the above-mentioned control device 40 is limited within the range of the elongated hole 53 , and its height can be freely adjusted and its position can be determined by using the sleeve 44 . However, when inserting the control device 40 into the guide rail member 52, an insertion opening not shown in the figure is used and is provided on the bottom surface of the guide rail 52 and the upper surface of the frame 55 together.

In the above description, when the weight of the main body 22 of the plate is too heavy, the number of its suspension wheels can be increased arbitrarily, for example, 2 to 4 suspension rollers 42 of the control device 40 are changed to 3 to 6 , or 4 pairs of 8, the weight of the plate main body 22 of each suspension roller 42 load can be reduced.

Moreover, when the control device 40 lifts a panel main body 22, the two suspension screws that are suspended Of the columns 21 and 21, it is sufficient to correspond to only one, and of course they may correspond to both.

According to the above description, this device has the following excellent effects, that is, because the main part is equipped with suspension rollers and independent rail guide wheels, in order to prevent the control device from jumping in the left and right directions, the frictional resistance is turned into a very small rolling friction, so the control device Movement is performed smoothly, improving the operability of the entire mobile partition. Moreover, the connection with the suspension stud is carried out through the bushing, so it is easy to determine the position of the control device, making the connection work particularly simple.

FIG. 11 shows another implementation example of the control device 40 , in which one of the pair of suspension studs 21 suspended from the slider 10 is screwed into the suspension block 56 . On the top of the hanging block 56, the upward direction becomes a convex shape, the thickness direction of the plate main body 22 is almost at the center and has the highest point, and the two sides are gradually inclined to form a curved surface.

The suspension block 56 is fitted into the hanging member 52A provided at the upper end portion of the panel main body 22 to suspend the panel main body 22 downward. As shown in FIG. 12 , the opening of the hanging part 52A is downward, and the cross section is in the shape of a 冂. It is fixed by the horizontal frame on the upper part of the plate main body 22, and there is a through hole through the sleeve 44 of the hanging block 56 on it. (See Figure 14). Here, the hanging block 56 forms a line contact with the hanging part 52A through the contact line located on the center line in the thickness direction of the plate main body.

As shown in Figure 14, now the main body of the plate is moved to a certain position by the guide slider 10, and then stops, the hanging block 56 is in the center of the hanging part 52A, that is, the center of the thickness direction of the main body 22 of the plate. The board main body 22 is suspended. Therefore, the straight line on which the panel main body 22 is in line contact with the suspension block 56 and the hanging member 52A can be swung to the center, and the straight line is almost on the center plane CP of the panel main body 22 . Therefore, when the center of gravity G of the panel body is above the central plane CP, the panel body 22 can always be hung in the correct vertical direction without any risk of inclination to the vertical plane.

Fig. 13 is to form a plane on the top of the hanging block 56, and the upper central part 52C of the hanging part 52B connected with the hanging block 56 is also feasible to form a concave shape downward in the transverse direction of the main body of the partition. Also make a straight line contact with the hanging block 56 and the hanging part 52A in the transverse direction of the plate main body 22, because the contact position of the two can be set to be almost at the thickness of the plate main body 22. Therefore, the board main body 22 can be suspended vertically as in the previous example.

As shown in FIG. 15 and FIG. 16 , the hanging block 56 can also hang the board main body 22 through the roller members 43A, 43B. That is, as shown in FIG. 11, the roller members 43A, 43A are placed at the center of the thickness direction of the control device 40, and at the same time, the lateral central portion of the roller members 43A, 43A is formed with a larger diameter as shown in FIG. 15 . The hanging block 56 and the hanging part 52B are almost all on the central plane CP of the board main body 22, and they can be made point contact by the roller parts 43A, 43A, so the board main body 22 can be hung down vertically. As shown in FIG. 16 , the roller member 43B may be formed into a simple cylindrical shape, and the upper surface 52C of the suspension member 52B may be formed in a concave shape downward.

When the hanging block 56 is provided with roller parts 43A or 43B, since the through hole 57 above the hanging part 52B becomes a long hole, according to the length of the through hole 57, the hanging block 56 can move relatively for the hanging part 52B, so If the control device 40 having such a roller member 43A or 43B is mounted on any one of the front or rear of the panel main body 22, the control device 40 can change the distance between the two suspension studs.

According to the above description, this device has the following excellent effects: since the hanging block is almost in the center of the thickness direction of the board main body to hang the board main body, when the board main body is stationary in a stable state, the thickness of the upper part of the board main body The center of the direction and the center of gravity of the board can be on the same vertical plane. At this time, the main body of the board can be hanged vertically correctly, so even when many boards are juxtaposed, there will be no unevenness on the surface, often with The orderly state forms a moving partition.

FIG. 17 is a sectional view showing another control device 40 of the present invention. The control device 40 is composed of a main body member 41 and a traveling rail 60 .

The traveling track 60 is formed as one by a pair of side frames 64 and an upper frame 63, and reinforcing plates 62 are attached on both end faces of the side frames 64, and the traveling track is a frame body with an open bottom. The center of the upper frame 63 is provided with an elongated hole 63a, and at its four corners, it is fixed together on the upper frame 55 of the board main body with 4 fixing screws 61,61.... Two pairs of suspension rollers 42 , 42 . . . and a connecting sleeve 44 are provided on the main body part 41 . The suspension rollers 42, 42 pass through a pair of through-holes disposed at the front and rear of the main body part 41. The through shafts 42a, 42a are fixed on both sides of the main body part 41 . When the positions of the suspending rollers 42 and 42 are determined, their peripheral parts protrude from the upper side of the main body member 41 , and their upper surfaces are in point contact with the upper frame 63 .

The coupling sleeve 44 is screwed into the center of the main body part 41 in an upright state, and driven into the locking pin 21b. A screw hole and a locking nut 21a are laid on the connecting sleeve 44, and the screw hole is used to connect the suspension stud 21 arranged on one side of the slider on the ceiling. The above-mentioned screw hole is very deep, and the height of the board main body 22 can be adjusted with it.

The main body part 41 makes the connecting sleeve 44 pass through the elongated hole 63a of the upper frame 63 and enters the traveling track 60, and at the same time, the moving surface of the suspension rollers 42, 42... is formed under the upper frame 63. And the interval of the opposite side frame 64,64 is set a little larger than the maximum installation width of the suspension roller 42... When the main body part 41 moves to the longitudinal direction of the traveling rail guide 60, its moving direction is controlled by the side frame 64. , 64 restrictions. In addition, its moving range is also limited by the length _D10 of the long hole 63a. When installing the above-mentioned traveling rail guide 60, a lower hole should be drilled in advance so that the fixing studs 61, 61 pass through the upper frame 55, and the installation can be completed very simply by tightening the fixing studs 61, 61... operate.

The board main body 22 assembled by the suspension studs 21 and the same number of control devices 40, its main body part 41 moves relative to the traveling track 60, so the board main body 22 can be allowed to be used as a hanging slider with the board main body 22 10, 10's direction independent sideways movement.

For example, as shown in Figure 18, along the suspension rail H, the partition board Pb ₁ moving in the direction of the arrow _K6 in the figure is perpendicular to the suspension rail H and parallel to the X direction of the suspension rail. When performing the operation of the partition board, In order to make each partition rotate in the direction of arrow K ₇ in Figure 18, the distance D ₂₁ between the suspension rail H and the wall surface W cannot be less than a certain value (see the dotted line in this figure).

Here, assume that the extension of the suspension rail H is H ₁₀ , pass the last partition Pb ₁ close to the sliding device 10 on the wall surface, and not send it to the suspension rail X, but let it stay on the extension H ₁₀ . The direction of the sliding device 10 is consistent with the direction of the suspension rail H. At this time, the control device 40 installed on the partition Pb ₁ allows the partition Pb ₁ to follow the arrow direction K ₈ in the figure regardless of the direction of the sliding device 10 . Move sideways, so the gap d between the partition Pb ₁ and the wall W can be adjusted arbitrarily. That is, the partition Pb ₁ moves in sequence according to the directions of arrows K ₆ , K ₇ , and K ₈ in the figure, and corrects the inclination relative to the wall W to achieve a visual upper balance. At the same time, according to the sandwiched gap d, use The movable sealing material Pb ₂ is filled in the separator Pb ₁ to completely seal the gap d.

According to the above description, the device has the following good effects. As according to the present invention, a pair of suspension studs, a pair of control devices and a traveling track are combined into parts, and the installation and disassembly of the dividing plate are just extremely easy. For example, it is very simple to repair some failures such as the damage of the hanging wheel, and the swimming track is not installed inside the partition, but it is integrated with the control device and laid outside the partition, so for the partition that has been set The supplementary installation project is also very simple, and the choice of whether to install the partition is also very simple according to whether to move sideways.
