Description

[Detailed explanation of the idea]

0001

[Industrial application field]

TECHNICAL FIELD The present invention relates to a hanging wheel device that is particularly useful when applied to heavy moving walls.

0002

[Conventional technology]

Traditionally, running rails have been laid on the ceiling or on the ceiling side of buildings, and A heavy lifting device with a height from the ceiling or near the ceiling to the floor is attached to a hanging wheel device that is movably mounted. A moving wall in which a large moving wall is suspended and supported is known.

0003 In order to support the large weight of the conventional moving wall as described above, the upper end of the moving wall is Install a hanging wheel device with multiple running wheels lined up along the moving direction of the moving wall. There are a lot of things. This is the wall itself that moves individually of the multiple running wheels that make up the hanging wheel device. This is a method adopted to ensure smooth running and safety by sharing the large weight of the vehicle. be.

0004 However, this type of movable wall is difficult to move within a large building by moving the movable wall. The movable wall can be installed to partition the booth space to form multiple booth spaces, or the movable wall can be used as one In order to create the original spacious building space by moving and removing it in one place. Since it is installed and used, it is frequently moved and installed or removed. , as mentioned above, is a suspended vehicle with multiple running wheels arranged in a row to support a heavy moving wall. If the device is installed on one moving wall, the running performance on straight sections of the rail is not good. Even if the rail is curved, there may be problems with running performance on curved sections or with the running wheels' ability to follow the rail. was there.

[0005] In other words, it is vertically long (large height) reaching from the ceiling to the floor, and it is heavy. The wall MW is manually pushed or pulled along the rail below its lower half. If you try to move it, pitching or rolling behavior will occur on this moving wall. A condition in which each running wheel is not completely supported by the rails (for example, when some of the running wheels are not supported by the rails). This may cause the vehicle to float off the ground or place an uneven load on the running wheels, making it difficult to drive smoothly. This tendency is particularly due to the yaw behavior of the moving wall that occurs in the curved section of the rail. This impedes the smooth and nimble running of the MW. If you look at this kind of driving disorder from a different perspective, Do not apply an unusual load to the shaft of each running wheel, suspension device, or rail. This is not desirable from a safety point of view.

[0006]

[Problem that the idea aims to solve]

Therefore, the present invention can move a heavy moving wall not only on a straight section of the rail, but also on a rail with a small radius. A hanging wheel that can run smoothly and easily even on curved parts of the road. The task is to develop a device.

[0008]

【Example】

Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows an example of the configuration of the device of the present invention. A perspective view, FIG. 2 is a front view of an example of the device of the present invention, and FIG. 3 is a left side view of the device of FIG. , FIG. 4 is a skeleton diagram showing essential parts of an example of the attachment relationship between the device of the present invention shown in FIGS. 1 to 3 and a moving wall. , FIG. 5 is a front view showing an example of the device of the present invention having eight sets of running wheel blocks.

[0009] In Figures 1 to 3, 1 is formed of an iron plate or the like to form a horizontally long rectangle when viewed from above. The base plates 2, 3, and 4 are the three through holes formed in the base plate 1. Of these three holes, two are provided approximately at the center of the base plate 1, and the bolts are A hanging rod in which a hanging rod member 5 having a plate shape is rotatably inserted through the upper surface side of the plate 1. This is a component mounting hole.

0010 The hanging rod member 5 attached to the mounting hole 2 has a head 5a formed on the member 5. The nut 5c screwed onto the male screw 5b prevents the plate from being removed from the plate 1. ing. The male thread 5b of this hanging rod member 5 is connected to the movable wall MW shown in FIG. It still works.

[0011] The through holes 3 and 4 are approximately symmetrical at the front and rear of the base plate 1 with respect to the center of the mounting hole 2. The running wheel blocks 6 and 7, which will be explained later, are mounted on the mounting shaft 8 through mounting holes formed at the same positions. , 9 for attachment.

0012 Since the running wheel blocks 6 and 7 have the same configuration and only differ in their mounting positions, Now, the configuration of the running wheel block 6 will be explained.

[0013] The block 6 is shown on both the left and right sides when viewed from the side of the mounting bracket 6a, which has an approximately L-shaped side surface. Two running wheels 6b, that is, a total of four running wheels 6b are mounted on each surface with horizontal shafts, and each of the above-mentioned With the wheel 6b facing the running direction, place the base plate at the lower wing part 6c of the bracket 6a. It is arranged without being fixed to the upper surface of the seat 1. In addition, 6d in the figure is the connection pin with the mounting shaft 8. This is a pin hole into which the pin is inserted.

[0014] The lower part of the running wheel block 6 has its bracket 6a on the base plate 1. A hole is formed on the upper part of the mounting shaft 8 inserted into the plate 1 from the lower surface side of the mounting hole 3. It is inserted into the mounting part 8a which has the shape of a holding wall, and the above-mentioned pin is inserted into the pin hole 8b formed in the mounting part 8a. This mounting shaft can be attached by inserting the connecting pin 10 through the pin hole 6d of the bracket 6a. Connected with 8.

[0015] In the mounting shaft 8, 8c is a boss formed below the mounting part 8a. The base portion 8c is loosely inserted into the mounting hole 3 of the base plate 1. 8d is the above in the axis 8 This is a flange portion formed below the boss portion 8c to prevent it from coming off.

[0016] Therefore, in the running wheel block 7 having the same configuration as the above running block 6, 7a is a block. Racket, 7b is the running wheel, 7c is the lower wing part, 7d is the pin hole, 7e is the floating regulation plate . In addition, in the mounting shaft 9, 9a is the mounting part, 9b is the pin hole, 9c is the boss part, and 9d is the flange. 11 is a connecting pin.

[0017] In addition, in the running wheel blocks 6 and 7, 6e and 7e are above the respective brackets 6a and 7a. Oscillation of the running wheel blocks 6, 7 formed to extend to (centering on the axes 8, 9) (swivel) comes into contact with a guide part (not shown) formed on the rail side, for example, at a branch part. This is a turning guide member that guides the user by rotating. In addition, the respective brackets 6a and 7a Guide rollers 6f and 7f supported by vertical shafts are installed before and after the . This is because the suspension device of the present invention runs on curved parts and branching parts of the rail R shown in Fig. 3. When the rolling blocks 6 and 7 approach, the swing of the blocks 6 and 7 is This is for guiding by the groove Rg of the rail at the curved part and the rollers 6f and 7f. Ru.

[0018] The above constitutes an example of the suspension device of the present invention. The locks 6 and 7 should be in a nearly symmetrical relationship with respect to the center of the base plate 1. For example, an even number of 3 or more, preferably 4 or more may be provided.

[0019] An example of the hanging wheel device according to the present invention configured as described above is as shown in FIG. On the center line of the moving wall MW in the running direction, a position where the front and back are approximately symmetrical; For example, two sets of the devices of the present invention are attached to the front and rear of the moving wall MW in the running direction. specifically When the movable wall MW is suspended and supported on the rail R, its position is on the center line of the movable wall MW. Find the center of gravity of the first half and the second half, and place the hanging device of this invention on the vertical line passing through each center of gravity. Position the hanging rod member 5 and fix the hanging rod member 5 to the upper horizontal frame member B of the movable wall MW. By attaching it to the front and back, each hanging wheel device can share the load almost equally between the front and rear. this The reason for this is that we want each running wheel of the suspension device to share the load almost equally. Ru.

[0020] The device of the present invention does not necessarily require the hanging wheel device and its mounting manner as shown in Figure 4. It's not something you do. That is, FIG. 5 shows one device of the present invention with running wheel blocks 6 and 7. This is an example formed by providing four. In Figure 5, 1A is used as the base plate, or In addition, since 5A functions as a hanging rod member, the hanging rod member 5 in FIGS. 1 to 4 is similar to that in FIG. In the example, the base plate 1 in Figs. 1 to 4 is used as a freely swingable connecting shaft. Functions as a connecting plate. In order to suspend and support a heavy moving wall like this , when further increasing the number of running wheels, two sets of running wheel blocks 6 are used in the present invention. , 7 are rotatably attached to the base plate. , by sequentially and repeatedly connecting these, each running wheel block 6, 7 can be connected to its own neck. It becomes possible to attach it to the movable wall MW so that it can swing freely.

[0021]

[Effect of the idea]

Therefore, the movable wall MW to which the device of the present invention is attached as described above is connected to the rail R. When running along the suspension rod members 5 and 5A of the suspension device of the present invention, as well as the front and rear The mounting shafts 8 and 9 of the running wheel blocks 6 and 7 and the connecting shafts (the reference numerals in Fig. 5) 5) is free, that is, rotatable about each axis with respect to the base plate 1. Therefore, the flexi In other words, it can be followed freely. In addition, each suspension device The running wheels 6b and 7b of the running wheel blocks 6 and 7 must be subjected to almost equal loads. The followability is ensured or supplemented by this.

[0022] Moreover, the running wheel blocks 6 and 7 themselves are constructed by simply arranging a large number of conventional running wheels in a row. Since it has a shorter wheelbase and can turn freely compared to the previous model, it is especially suitable for rail R. Smooth running is possible with an extremely small radius on small-diameter curved sections.

[0023] In this way, each of the running wheel blocks 6, 7 is individually positioned in the direction of travel. It has good followability for left and right distortions, left and right curves, or left and right curves. Due to this, in the past, a large number of running wheels were simply connected in series to the above-mentioned rail. In a suspended suspension system with rows of The lifting of the hanging wheel device and uneven running caused by contact and galling have been fixed. This can be prevented without the need for guide rollers or the like.

[0024] In addition, when two or more sets of the hanging wheel device of the present invention are provided for one movable wall MW, For example, when installed as shown in Fig. 5, the individual running wheel blocks 6, 7, In addition, the base plates 1 and 1A are connected to the mounting shafts 8 and 9 and the hanging rod members 5 and 5A. Since it is swingable, even if the curve radius of the rail R is made a little tighter, the direction can be changed smoothly. It is possible to realize switching driving.
