BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a revolving door device provided at an opening of a building or the like.

[0002]

2. Description of the Related Art Generally, in this kind of revolving door device, an opening facing in a radial direction is formed, and a rotating wall that divides the entrance into a plurality of sections is formed in a cylindrical wall body that forms a substantially cylindrical entrance. There is a configuration in which the door is rotatably provided, and with such a configuration, the openings opposed to each other in the radial direction formed in the cylindrical wall body are prevented from being simultaneously opened to be in a communicating state, The indoor temperature can be constantly maintained. By the way, as a revolving door, for example, as disclosed in Japanese Patent Publication No. 4-37912, a door is provided at a central position of a partition body at an entrance / exit portion, and integrally provided at an outer end of the partition body, 2. Description of the Related Art A revolving door device including an arc-shaped body that opens and closes an opening of a cylindrical wall with rotation of a partition body is known (hereinafter, referred to as “prior art”).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to solve the above-mentioned problems. And a rotating door that is installed along the radial direction of the cylindrical wall and that opens and closes the opening of the cylindrical wall with rotation, and the rotating door is mounted on a rotating ceiling frame above the rotating door. In order to be able to suspend and rotate integrally, an annular guide rail is provided horizontally inside the support of the cylindrical wall,
The rotary ceiling frame is provided with a plurality of running rollers for rolling on the running roller guide surface of the annular guide rail. By doing so, the adjustment of the horizontal level between the rail, the frame, and the rollers can be simplified, and the time required for the total adjustment as a unit of the three can be greatly reduced.
In this case, it is preferable that the outer diameter of the running roller is larger than the inner diameter in the radial direction of the annular guide rail. This is because the contact of the traveling roller with the rail guide contact surface can be made uniform, thereby reducing the occurrence of uneven wear of the traveling roller surface. Further, in this case, it is preferable that the annular guide rail is constituted by a plurality of divided rails, and the running roller guide surfaces of the divided rails are formed by butt connection. By doing so, not only the mounting and horizontal adjustment of the rails become easier, but also the convenience of transportation is improved. In this case, the butt line (visible line) appearing on the traveling roller guide surface at the butt portion of the split rail may be larger than the radial cutting line of the annular guide rail passing through the butt portion. preferable. By doing so, in combination with the shape of the traveling roller according to the invention of the present invention, the contact noise (passing sound) with the butting line generated when the traveling roller passes through the guide surface of the butting portion is reduced. Rolling can be performed smoothly.

FIG. 1 shows an embodiment of the present invention.
Explanation will be made based on the drawings of FIG. In FIG. 1, reference numeral 1 denotes a revolving door device provided at a body opening. A cylindrical wall 2 constituting the revolving door device 1 forms a substantially cylindrical entrance / exit portion 4. A pair of openings 4a and 4b are formed at the indoor and exterior positions (front and rear portions) of the cylindrical wall body 2 so as to face the radial direction of the cylindrical wall body 2. At the upper end of the cylindrical wall 2, a circular ceiling 3 formed with a substantially circular ceiling surface 3a and a curtain plate portion 3b bent toward the outer peripheral edge of the ceiling surface 3a is formed. It is attached integrally. However, the ceiling surface 3a and the curtain plate portion 3b are separate bodies, and the ceiling surface 3a rotates about the center P of the frame assembly, but the curtain plate portion 3b is immovable to the last. The ceiling surface 3a and the revolving door 5 are integrally rotatably disposed about a center P of the ceiling surface 3a.
A is set so as to rotate counterclockwise in plan view by receiving the driving force of the power machine supported on the side of the circular ceiling 3 together with a. In the present embodiment, the rotation of the revolving door 5 (including the rotation of the ceiling surface 3a) will be described on condition that the driving force of the revolving power machine 18 is used.
Reference numeral 8 denotes a roller which is directly connected to the output shaft 19, and may be provided separately from and independently of the traveling roller 15 (for example, by directly driving and rotating the center fixed shaft 12). . In addition, the present invention can be implemented as it is even in a method that does not use the rotary power machine 18 (for example, a method of rotating a revolving door manually).

FIG. 2 is a plan sectional view of the revolving door device 1. Reference numeral 5 denotes a revolving door, which is a first partition body 6 extending in a radial direction passing through a rotation center formed of a double-opening openable door body, and is connected to the first partition body 6 orthogonally. A second partition body 7 extending from both ends of each second partition body 7 and extending toward the cylindrical wall body in an inclined state with respect to the first partition body 6 with respect to the second partition body 7. And 8. Numeral 9 denotes a support made of a hollow square pipe that serves as an aggregate for erecting the cylindrical wall 2. In the present embodiment,
Posts 9 are provided at both ends and an intermediate portion inside the cylindrical wall body 2, and a total of six revolving door devices 1 support the device. The strut 9 extends from the floor of the revolving door device 1 to the upper surface of the circular ceiling 3, and also serves as a support member for the circular ceiling 3.

FIG. 3 is a cross-sectional view of the inside of the circular ceiling 3.
FIG. 3A is a longitudinal sectional view, and FIG. 3B is a plan sectional view. Reference numeral 10 denotes a fixed ceiling frame provided above the inside of the circular ceiling portion 3, and is constituted by a frame assembled in a substantially circular shape having a diameter slightly smaller than the diameter of the circular ceiling portion 3. The fixed ceiling frame 10 is supported and fixed to a first support member 11 that protrudes inward from the support 9 in the circular ceiling 3. The horizontal level of the first support member 11 is held in advance. The center of the frame P, which is the center position of the fixed ceiling frame 10 (the center P is a center forming a concentric circle with the circular ceiling portion 3, the circular ceiling surface 3a, and the rotating ceiling frame 13) is not shown. The bearing is mounted, and the center fixed shaft 12 is hung on the bearing. Reference numeral 13 denotes a rotating ceiling frame, which is located in the circular ceiling portion 3 below the fixed ceiling frame 10 and is formed into a substantially circular shape having a diameter slightly smaller than the diameter of the circular ceiling portion 3 like the fixed ceiling frame 10. It is composed of a frame. At the center P of the rotating ceiling frame 13, a bearing bearing device 14 for inserting the center fixed shaft 12 is provided, and the rotating ceiling frame 13 is rotatable about the center fixed shaft 12. The center fixed shaft 12 is for exclusively controlling the “blur” caused by the rotation of the rotating ceiling frame 13. In addition, since the fixed ceiling frame 10 is assembled in the circular ceiling portion 3 in a horizontal state, the traveling roller 15 is also provided with the rotating guide frame 16 on the rotating ceiling frame 13 that is axially inserted into the center fixed shaft 12 that hangs down from the fixed ceiling frame 10. Is mounted on the traveling roller guide surface 16a, and is mounted in the circular ceiling portion 3 while maintaining a horizontal state.

Further, the fixed ceiling frame 10 and the rotating ceiling frame 13 constitute a skeleton by mainly assembling steel materials in a lattice shape with respect to the center P of the shaft assembly. An angle material, a C-type steel, or the like is used as the steel material. Note that the peripheral edges of the fixed ceiling frame 10 and the rotating ceiling frame 13 do not necessarily need to be formed in a circular shape.
The fixed ceiling frame 10 is horizontally and firmly fixed to the column 9 so that the center fixed shaft 12 does not "blur". The rotating ceiling frame 13 can fix the traveling roller 15 which traces the same circumference. A centering shaft P of 13 has an insertion hole through which the center fixed shaft 12 is inserted, and any structure that can hang the revolving door 5 or the like with a sufficient safety factor may be used.

In the present embodiment, a plurality of running rollers 15 are mounted along the periphery of the rotating ceiling frame 13. The traveling rollers 15,... Are located at equal positions from the center P of the shaft assembly, and their positions are preset so as to roll on traveling roller guide surfaces 16a of annular guide rails 16 to be described later. Some of the traveling rollers 15 (the number of which is determined by the weight of the revolving door, etc.) of the plurality of traveling rollers 15 rotate the revolving ceiling frame 13 in rotation and in conjunction with the driving. Ceiling surface 3a to be rotated and an output shaft of a rotary power machine 18 for rotating the rotary door 5.

FIG. 4 shows a rotary power machine 18 and a rotary power machine 18.
FIG. 4 is a diagram showing a relationship between the output roller 19 and the traveling roller 15 when the output shaft 19 is mounted on the output shaft 19. Here, the roller surface W of the running roller 15 is preferably a flat roller having the same inner and outer diameters. Here, the inner diameter refers to the roller diameter on the side of the shaft center P, and the outer diameter refers to
The roller diameter on the side of the support 9 is referred to. Generally, the traveling rollers 15 having the same inner and outer diameters are used. More preferably, the outer diameter of the traveling rollers 15 (the roller shaft is omitted) as shown in FIG. The idea is to use an umbrella car with a gentle corner. When the running roller 15 provided on the peripheral portion of the horizontal rotating ceiling frame rolls on the running roller guide surface 16a of the annular guide rail 16 located at the same horizontal level, the inner and outer diameters of the roller surface w are the same. Then, since the angular velocity is the same between the inner diameter and the outer diameter, a difference between the inner and outer diameters easily occurs in the abrasion of the roller surface w,
This is because it is difficult to secure long-term stable rolling performance of the traveling roller 15.

The inner and outer diameters of the running roller 15 are determined by the following formula. That is, as shown in FIG.
The width of the roller surface w is W, the outer diameter is d1Φ, and the inner diameter is d2.
Φ, the rotation diameter is DΦ, and the taper angle between the inner and outer diameters is θ. now,
The rolling distance at point A (outer diameter) when the traveling roller 15 makes one rotation of the rotation diameter DΦ is πD. Similarly, the rolling distance at point B (inner diameter) is π (D−2W). Assuming that the number of rotations of the traveling roller 15 at this time is N, A
The rotation speed N at the point (outer diameter) is D / d1, and the rotation speed N at the point B (inner diameter) is (D-2W) / d2. Since d1 and d2 are set so that N is the same at both points A and B, D / d1
= (D-2W) / d2. Therefore, d2 = (D-2W)
× d1 / D and the taper angle θ, tan θ = (d1
−d2) / 2W = (d1- (D-2W) × d1 / D) /
2W. Therefore, θ = tan-1 {d1 / 2W [1-
(D-2W) / D]}.

When the .theta. Value is determined in this manner, it is necessary to incline the rotary drive 18 directly connecting the running roller 15 to the output shaft 19 in the direction of the center P of the shaft assembly by .theta. For this purpose, the fixed pedestal 20 of the rotary drive 18 is also inclined with respect to the horizontal level by θ degrees. All the traveling rollers 15 are attached to the peripheral edge of the rotating ceiling frame 13 so as to satisfy such conditions.

The material of the roller body of the traveling roller 15 is made of steel or hard resin, but is not limited thereto.

Next, the annular guide rail 16 will be described with reference to FIGS. The annular guide rail 16 is for supporting and guiding the traveling roller 15,
It is fixed to a second support member 17 extending in the direction opposite to the columns 9 extending in the inner periphery of the curtain plate portion 3b. The annular guide rail 16 is formed by processing an L-shaped steel into a circular shape.

FIG. 8 is an assembly view of the annular guide rail 16, which can be formed by processing a long single L-shaped steel into a circular shape. preferable. This is because a uniform horizontal guide surface for rolling the running roller 15 can be formed, and furthermore, it is convenient for transportation and on-site construction. Each split rail 1
6 'is connected as shown in FIG.
The connection between them is made such that the running roller guide surfaces 16a are abutted.

In this case, the butting line (visible line) X appearing on the guide surface of the butted portion 16b of the split rail 16 'is larger than the radial cutting line Y of the annular guide rail passing through the butted portion 16b. Is preferable. Most commonly, the direction of the butting line (visible line) X coincides with the radial direction of the annular guide rail 16.
Although the processing of the butting portion 5 'is easy, if it is larger than the radial cutting line Y of the annular guide rail 16, the traveling roller 15 passes through the butting line (visible line) X. This is because the generation of sound at the time can be reduced, and this is considered to be a better matching method.

The reason why this matching method is considered to be a better method is specifically as follows. That is, if the direction of the butting line (visible line) X is set to the direction coinciding with the cutting line Y, the butting portion 16
If a small step (not shown) occurs in b, the entire roller width W of the traveling roller 15 must be overcome when passing through the step (there may be a step drop, but the description will be duplicated and will be omitted). . As a result, since the entire roller width W gets over the step, a passing sound accompanying the step is generated from the entire running roller width W. On the other hand, if the abutting portions 16b are cut obliquely to each other, for example, when the traveling roller 15 passes through the abutting line X, a part of either the inside diameter or the outside diameter of the traveling roller 15 gets over the step. Will be. That is, in this case, only a part of the roller width W of the traveling roller 15 first comes into contact with the step. As a result, compared to the sound generated when the entire roller width W hits the step, the generated sound can be reduced. The same applies even when the running roller 15 is an umbrella wheel. When a step occurs in the butted portion 16b, the butted portion 1
It is of course possible to polish 6b so that it is nearly flat.

Here, the butt line X appearing on the running roller guide surface 16a of the butt portion 16b of the split rail 16 'is set to be larger than the radial cutting line of the annular guide rail 16 passing through the butt portion 16b. 8, the butted portion 16b of the divided rail 16 'is cut obliquely so as to be inclined, as well as curved (X2, X3) or uneven (X4) as shown in FIG. It may be something. In other words, "make larger" than the radial cutting line Y of the annular guide rail 16 means that the length of the butting line (visible line) X appearing on the traveling roller guide surface 16a of the butting portion 16b is cut. It means longer than line Y. Conversely, it is not possible to make the butting line (visible line) X shorter than the radial cutting line Y of the annular guide rail 16. Therefore, all butting lines (visible lines) X other than the cutting line Y are longer than the radial cutting line Y of the annular guide rail 16.

In the embodiment of the present invention configured as described above, the rotating door 5,
Since the circular ceiling surface 3 a is integrated with the rotating ceiling frame 13, it rotates in the same direction as the rotating ceiling frame 13. At this time, the traveling rollers 15,... Share all the loads of the hanging members such as the rotating door 5, the circular ceiling surface 3a, the rotating ceiling frame 13, and the rotating power machine 18,
The running roller guide surface 16a of the annular guide rail 16 is rolled. The traveling roller 15 mounted on the output shaft 19 of the rotary power machine 18 performs rotational traction at the reduced rotation speed of the output shaft 19 as a matter of course.

According to the present invention, since the annular guide rail 16 is formed by processing a simple L-shaped steel into a circular shape, it is necessary to use a T-shaped rail as in the prior art. Absent. As a result, it is easy to manufacture the split rail. Also, the prevention of the step at the butted portion can be reduced as much as possible. Further, it is not necessary to support both lower surfaces of the flanges of the T-shaped rail with the rollers, which is necessary in the case of the T-shaped rail, so that not only the number of rollers can be reduced, but also the rail, frame and rollers can be adjusted to a horizontal level. Etc. can be simplified.

The running rollers 16,... Are arranged on the running roller guide surface 16 at the abutting portion 16b of the split rail 16 '.
When passing through the butting line X shown in FIG. 5A, as described above, even if there is a step in the butting line X, it is possible to get over while reducing the impact sound as much as possible.

Further, since each running roller 15 has a slight taper angle between the inner and outer diameters, a part of the width of the roller surface w does not slip and the entire width W of the roller surface w , It is possible to apply a uniform rotational force.
