Description

[Detailed Description of the Invention] The present invention provides a wall that can be moved to a hanger rail installed in the ceiling, that is, a movable wall, in order to freely partition an exhibition hall, conference room, etc. according to the number of people accommodated, the function of the room, etc. This relates to a mobile wall hanging wheel for suspending, moving, transporting, and installing hangers, and in particular, the eccentricity between the center of the mobile wall, that is, the axis of the mobile wall hanging tool, and the center line of the vertical wheels rolling on the hanger rail. At the same time, the hanging wheel body to which the vertical wheels and movable wall hanger are attached is made bendable, which not only reduces the cost of the hanger rail and ceiling structure, but also makes it possible to smoothly bend and run on the bent hanger rail. This invention relates to a controlled refraction suspension wheel.

As shown in FIGS. 1a and 1b, a conventional movable wall hanger has one wheel 2 that rolls on the upper surface of a hanger rail 1 and a movable wall 3 that is provided concentrically with the center line j of the wheel 2. It is known that the movable wall 3 is connected by an arm 4 to prevent inclination due to eccentricity, but in this case, since there is only one wheel 2, the arm 4 easily swings in the directions of arrows 5 and 6, preventing movement. wall 3
The hanging condition is not stable.

Furthermore, since the wheels 2 and the movable wall 3 are arranged concentrically, the distance 1 between the wheels 2 and the arm 4 inevitably becomes large, and the horizontal axis 4 of the arm 4 becomes long, which increases the weight of the movable wall 3. There is a problem in that the deflection of the horizontal axis 4 becomes large.

As a means to solve this problem, lower running plates 7', 7 of a hanger rail 7 having a C-shaped cross section as shown in FIG.
A hanging wheel device is considered in which a movable wall 3 suspended from a hanging wheel main body 8 is suspended by wheels 2 and 2' running above.
The number of is 2 on each side of the suspension wheel body a, as shown in the same figure b.
In the case where a total of 4 pieces are installed, or one piece on one side as shown in Figure C,
In the case where two of them are placed on the other side, the deflection of the horizontal axes 9 and 9 and the deflection in the directions of arrows 5 and 6 are almost eliminated, but C
A hanger rail 7 having a special shape such as a letter shape is required, and such hanger rails are installed vertically and horizontally under the ceiling, making them extremely expensive and contributing to an increase in the cost of the entire movable wall.

In addition, when one suspended wheel body runs on a plurality of wheels, it is possible to move straight straight smoothly, but it is extremely difficult to make bending movements such as turning right or turning left.

The present invention overcomes the problems and difficulties inherent in the conventional movable wall suspension wheels as described above, reduces the cost of the entire movable wall, provides a stable suspension vehicle without wobbling or deflection, and has smooth bending motion. The purpose of this is to provide a hanging wheel that enables the use of a hanging wheel, and its main points are that two hanging wheel bodies each having an L-shaped cross section are connected in a bendable manner, and a hanger rail is mounted on the inside of the vertical wall of each hanging wheel body. Attach a vertical wheel that rolls along the guide rail provided at the bottom of the hanger rail to the horizontal wall of each of the hanging wheel bodies, and install a horizontal wheel that rolls along the guide rail provided at the bottom of the hanger rail. It is located at a point where the axis of the tool and the center line of the vertical wheel are eccentric.

Next, embodiments embodying the present invention will be described in detail with reference to the drawings from FIG. 3 onwards.

Here, FIG. 3 is a side view including a partial cross section of a refracting suspension wheel according to an embodiment of the present invention, FIG. 4 is a view taken along the line A-A in FIG. 3, and FIG.

In FIGS. 3 to 5, of the two hanging wheel bodies that are refractably engaged around the axis p of the hanging tool 36, one is called the front wheel main body 11 and the other is called the rear wheel main body 12. .

First, the bending mechanism of the suspension wheel bodies 11 and 12 will be explained below.

Both suspension wheel bodies 11 and 12 both have an L-shaped cross section with a vertical wall 13.13' and a horizontal wall 14.14', and the horizontal wall 14 of the front wheel body 11 has a front protruding wall 16 facing rearward. The horizontal wall 14' of the rear vehicle body 12 has a rear protruding wall 15 facing forward, and the protruding walls 15 and 15' are overlapped with each other with a gap 16 between them, with the lower thrust bearing 17 interposed therebetween. There is.

A cylindrical core member 18 screwed vertically into the center of the rear projecting wall 15 has its outer periphery 19 circumscribing the lower race 20 of the lower thrust bearing 17, and a through hole 21 provided at the center of the front projecting wall 15. It is loosely fitted inside.

Of an upper bearing hole 22 and a lower bearing hole 23 bored in the front protruding wall 15 concentrically with the through hole 21, the lower bearing hole 23 is circumscribed by the upper race 24 of the lower thrust bearing 17. The lower race 26 of the upper bearing 25 inserted into the upper bearing hole 22 is circumscribed in the upper bearing hole 22, and the upper race 27 is inscribed in the outer periphery 19 of the cylindrical core member 18.

A front protruding wall 15 is located between the flange 30 of the presser cap 29 screwed into the female thread 28 cut into the upper part of the cylinder core 18 and the rear protruding wall 15' integrated with the cylinder core 18. The above-mentioned upper and lower thrust bearings 25.17, which are press-fitted to the upper and lower sides of the central projecting piece 31, are inserted.

An insertion hole 32 penetrates through the center of the cylinder core material 18, and a bolt head insertion hole 34 is continuous to this via a step 33. A movable wall hanging tool 36, which has a head 35 on its upper part that comes into contact with the movable wall, is rotatably inserted into the insertion hole 32.

Fan-shaped locking member 3 welded to the lower surface 37 of the front projecting wall 15
8 and 38 are fan-shaped fan-shaped parts which are arranged symmetrically in front and behind the center line k of the front projecting wall 15, sandwiching the axis p of the hanging tool 36, and which are welded to the upper surface 39 of the rear projecting wall 15'. locking material 40,4
0 is on the center line m that is perpendicular to the center line K' of the rear projecting wall 15 and passes through the axis p of the hanging tool 36, and is symmetrical to the left and right of the axis p of the hanging tool 36, and the above-mentioned locking When the center lines k and k' of the front vehicle body 11 and the rear vehicle body 12 are in a straight line as shown in FIG. and the center angle β of the fan shape of each locking member so that the angle α formed by each side 41 and 42 of 40 is 45 degrees.
is determined, and the height h of each locking member 38, 40 is determined to be smaller than the width H of the gap 16, but larger than half of the width H, so that the front and rear vehicle bodies 11.12 When bent by 45 degrees, the locking members 38 and 40 collide and further bending is prevented.

Next, the traveling mechanism of the hanging wheel body will be explained.

That is, the vertical walls 13. of each hanging wheel body 11.12. Inside the vertical wall 13.13', vertical wheels 44, 44' are rotatably mounted on a horizontal shaft 43.43' fixed horizontally to the vertical wall 13.13', and the vertical wheels 44.44' have an H-shape. It rolls in the axial direction of the hanger rail 45 on one surface of the bottom sides 46, 46 of the hanger rail 45 laid down.

A guide rail 48 having a U-shaped cross section is welded to the lower surface 47 of the hanger rail 45 coaxially with the hanger rail 45.
Two horizontal wheels 49 and 49' inserted inside the front and rear vehicle bodies 1 are supported by bearings 50 and 5σ, respectively.
1, 12 horizontal walls 1 4. It is rotatably attached to vertical shafts 51, 51' fixed perpendicularly to the guide rail 48, and its outer peripheral surface 52, 52' is drum-shaped, and rotates while contacting the inner surface 53 of the guide rail 48. move.

To explain the structure of the horizontal wheel 49 or 49' in more detail, a cover member is attached to a threaded portion 56 carved in the upper opening of a wheel body 55 that is fitted from below to a bearing 50 that is fitted and fixed to the tip 54 of a vertical shaft 51. 57, and connect the lid material 57 and the wheel body 55.
The bearing 50 is clamped and held between the lower flange 58 of the holder and the lower flange 58 of the holder.

Further, as shown in FIGS. 4 and 5, the axis p of the hanging tool 36 and the center line n of the vertical wheel 44.44' are offset by a distance S.

The hanger rail 45 may be used by laying an H-shaped rail horizontally as shown in FIG. 4, but as shown in FIG. It can be used as a running surface or two L-shaped rails 45 as shown in Figure b.
It is also possible to use rails b and 45b back to back, or to use one or two U-shaped rails as shown in c and d of the figure.

Furthermore, the guide rail installed under the hanger rail is not the above-mentioned U-shaped rail, but an L-shaped rail 48a as shown in FIG.
You may install two or one.

When the above-mentioned hanging wheel is placed on the hanger rail 45 in the state shown in FIG.
A rotational moment is generated around the contact point R between the horizontal wheel 49 and the vertical wheel 44, and the outer circumferential surface 52 of the horizontal wheel 49
The movable wall is pressed against the inner surface 53 of the hanger rail 46 and travels in the axial direction of the hanger rail 46 by rolling of the vertical wheels 44 on the hanger rail 46 while maintaining the vertical state.

As shown in FIG. 9, when the movable wall 60 travels while being suspended from the hanging tool 36 by the hanging wheel 59 below the bent hanger rail 45', the horizontal wheels 49, 49' are guided to the guide rail 48. As a result, the front vehicle body 11 and the rear vehicle body 12 are bent freely around the hanging tool 36 as shown in the figure, and the vertical wheels 44, 44' roll smoothly on the bottom side 16' of the hanger rail 45'. do.

The reason why the front and rear car bodies 11 and 12 are freely bent in this way is that the rear protruding wall 15 of the rear car body 12 and the front protruding wall 15 of the front car body 11 have a gap 16 in between, as is clear from FIG. The rear protruding wall 15, the cylinder core 18 integrated therewith, the presser cap 29, and the front protruding wall 15 are only connected via a thrust bearing 17.25, and the thrust This is because the front vehicle body 11 and the rear vehicle body 12 are easily bent about the axis p of the hanging tool 36 due to the smooth rotation of the bearings 17,25.

Furthermore, when the front and rear vehicle bodies 11, 12 are bent by 45 degrees, the respective side surfaces 41, 42 of the locking members 38, 40 come into contact with each other, so that they cannot be bent any further.

This prevents the front and rear vehicle bodies 11, 12 from being bent more than necessary, which would impair operability during assembly.

Next, other bending mechanisms of the front and rear vehicle bodies 11 and 12 will be explained with reference to FIG.

In the same figure, the front protruding wall 15a of the front vehicle body 11 and the rear protruding wall 15a' of the rear vehicle body 12 have a gap 16' in between, and an upper thrust bearing 61 is sandwiched between them, and the front protruding wall 15a is located at the center of the front protruding wall 15a. The above upper thrust bearing 61 drilled in
A movable wall hanging tool 64 is inserted into an insertion hole 62 coaxial with the upper race 63 of the upper thrust bearing 61 and circumscribed with the upper race 63 of the upper thrust bearing 61. The insertion hole 65 is loosely fitted into the hole 65 and is provided at the lower part of the rear protruding wall 15a'.
It is fitted into a lower thrust bearing 66 coaxial with the lower race 67, and is circumscribed by the lower race 67.

The central projecting piece 70 of the front projecting wall 15a is located between the head 68 of the hanging tool 64 and the nut 69 screwed onto the lower part thereof.
The front vehicle body 11 and the spacer T2 are sandwiched between the upper thrust bearing 61, the central protruding piece 71 of the rear protruding wall 15a', the lower thrust bearing 66, and the spacer 72, and rotate integrally via the hanging tool 64. , and the nut 69, and the rear vehicle body 12 are connected only through thrust bearings 61, 66.

Therefore, in this case as well, the front vehicle body 11 and the rear vehicle body 12 can be bent smoothly around the hanging tool 64.

As described above, the present invention is provided with vertical wheels that roll on the hanger rail only on one side of the hanging wheel body, so there is no need for an expensive hanger rail such as a C-shaped rail.
Commercially available H-shaped steel, ■-shaped steel, L-shaped steel, U-shaped steel, etc. can be used, and these steel materials can also be used as ceiling beams, making it possible to significantly reduce costs. Because it is eccentric, the deflection of the transverse axis (horizontal axis) is so small that it can be ignored, making the hanging condition stable.In addition, since there are multiple vertical wheels and the horizontal wheels are in contact with the guide rail, the movement in the front and back direction ( It is possible to avoid vibrations in both the direction of arrow 6) and the lateral direction (direction of arrow 5), and the hanging and running conditions of the movable wall are extremely stable. Tilting can be completely avoided.

In addition, since the hanging wheel body is divided into two parts and connected in a bendable manner, it can smoothly bend even on bent hanger rails, significantly increasing the freedom of movement of the moving wall and partitioning. It was extremely successful.
