Abstract

PURPOSE:To make input capacity constant, which is required all the way from the beginning to the end by the movement of an object by connecting a turning shaft which rotatably supports the weight of the object capable of being moved, to the other end of a turning lever one end of which is provided in such a way as to be freely turned from a fixed surface, providing a bracket which rotatably support the neighbor of the end section of the object, and thereby transmitting torque to the turning shaft. CONSTITUTION:A bracket 2 is disposed at the end position of a chair B, a turning shaft 8 is disposed roughly at the center of the chair, and a turning lever 5 is positioned roughly in parallel with a wall surface A1. When a motor is energized, a worm 10 is rotated, its torque is transmitted to a worm gear 11, however, since the turning shaft 8 will not be rotated, its reaction is thereby transformed into torque for rotating the chair B integrated with its gear box in the direction indicated by an arrow head (a). Since one end of the chair B is restrained by a pin 2a, torque is thereby produced, which allows the chair B to be turned around the pin 2a in the direction indicated by an arrow head (b), also allows the turning lever 6 to be turned to the direction indicated by an arrow head (c), and concurrently allows the chair to be moved along a guide rail 1 via the bracket 2 in the direction indicated by an arrow head (d), so that input required for turning is thereby kept roughly constant.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention In a railway vehicle, the present invention rotates a passenger's chair arranged in parallel with a car window in a direction perpendicular to the car window, or uses a bookcase or cabinet arranged along the wall as a wall surface. For example, rotate it in the right angle direction,
The present invention relates to a rotation moving device for rotating an object by approximately 90 degrees.

[0002]

2. Description of the Related Art Conventionally, in order to rotate a vehicle chair, a bookcase, or a cabinet arranged along a vehicle window or a wall surface in a direction at a right angle, it is generally done by human power. In order to perform a large number of chairs manually, it takes time and requires a considerable number of workers.
When the bookcases and cabinets are rotated in a store or the like, it takes a short time because the quantity is small, but there is a problem that the bookcases and the cabinets are heavy, which causes heavy labor.

[0003]

Therefore, it is conceivable to use a link mechanism to rotate by a driving force of a motor or the like. However, in a moving device using a known link mechanism, the transmission force of the rotational movement depends on the rotation angle of the arm. There is a problem in that the device becomes large in scale because it changes greatly and the capacity of the power generation source needs to be determined by the minimum value of the transmission force.

Further, in the known link mechanism, there is a problem that the link mechanism largely protrudes to the outside of the storage space for the object, which narrows the vehicle space or the store area.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide output and input from the beginning to the end of movement of an object between the power generation source and the input end of the moving object. Since the amount of force is kept substantially constant, the power generation source can be reduced in capacity, and since it can be provided on the back surface of the object as a device for moving and positioning the object, the working area can be extremely small regardless of the position of the object. An object is to provide a rotation moving device for an object that can be widened.

[0006]

SUMMARY OF THE INVENTION The object rotating and moving apparatus of the present invention is intended to solve the above-mentioned problems, and means for fixing the one end of a rotating shaft for supporting the weight of a movable object. The other end of the swiveling lever provided so as to freely swivel from the surface is integrally connected to transmit the rotational force to the swivel shaft provided on the object side, and the vicinity of the end of the object is freely rotatable. It comprises a bracket to be supported and a guide rail to guide the movement of the bracket.

[0007]

In the object rotational movement device of the present invention constructed as described above, the rotational force applied to the turning shaft by the transmitting means is applied to the transmitting means as a reaction force because the turning shaft is fixed to the turning lever. Returning, the reaction force is used to move the object along the guide rail, and the turning lever rotates the object. Therefore, the object rotates while moving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the object rotating and moving apparatus according to the present invention will be described below with reference to FIGS. In addition, in the present embodiment, the case where the invention is applied to a vehicle chair is shown. FIG. 1 is a plan view schematically showing an application to a vehicle chair, FIG.
Is a specific side view of the above, and FIG. 3 is an enlarged side view of the same.

A is a vehicle such as a railroad vehicle, B is a passenger chair which is a moving object, B ₁ is a backrest portion, and B ₂ is a seat which is attached to the backrest portion B _{1 so as} to be able to move up and down. It is a department. 1
Is a guide rail mounted along the longitudinal direction of the vehicle window side wall surface A ₁ of the vehicle A, 2 is a bracket rotatably mounted by a pin 2a at one end on the back side of the backrest B ₁ , and has a tip The pulley 2b and the roller 2c on the side are attached, and the pulley 2b is guided by the first rail 1a of the guide rail 1 to regulate the movement in the vertical direction.
c is guided by the second rail 1b to regulate the movement of horizontal traveling.

[0010] 3 in the parallel state with respect to the chair B wall surface A _1, the bracket 2 has a pair of upper and lower attached to the wall surface A ₁ facing the chair B opposite mounted fork, 4 the Base shaft 5 supported by fork 3
Are a pair of turning levers, one end of which is fixed above and below the base shaft 4.

6 is a socket fixed above the center of the backrest B _{1 in} the lateral direction, 7 is a gear box mounted on the rear surface of the seat B _{2 in} the lateral center, and 8 is an upper end supported by the socket 6. The lower part of the swivel lever 5 is fixed to a non-rotatable state by a key 5a with a swivel shaft pivotally supported by a bearing portion 7a of the gear box 7. The lower end of the turning shaft 8 is extended to the floor surface A ₂ of the vehicle A, and the caster 8a attached to the lower end allows the chair B to move smoothly.

Reference numeral 9 is a motor mounted integrally with the gear box 7, and a worm 10 is fixed to its output shaft. Further, the swivel shaft 8 penetrating the gear box 7
The key 1 is a worm gear 11 that meshes with the worm.
Although it is movable in the vertical direction by 1a, it is fixed immovably against rotation.

Next, based on the above configuration, when the chair B is parallel to the wall surface A _{1 of the} vehicle A (solid line state in FIG. 1), the chair B is attached to the wall surface A ₁ . The case of rotating and moving in the orthogonal direction will be described. That is, the bracket 2 is arranged at the end position of the chair B, the swivel shaft 8 is arranged substantially at the center, and the swivel lever 5 is positioned substantially parallel to the wall surface A ₁ .

In this state, when the motor 9 is energized, the worm 10 is rotated. This rotational force is transmitted to the worm gear 11 and tries to rotate the swivel shaft 8 fixed by the key 11a.
Since it is in a state where it cannot be rotated by the key 5a,
The turning shaft 8 is in a state in which it cannot rotate.

Therefore, as a reaction force, the worm 4 tries to rotate around the worm gear 11. This reaction force becomes a torque for rotating the chair B integrated with the gear box 7 in the direction of arrow a. Therefore, since one end of the chair B is restrained by the pin 2a, torque is generated to rotate the chair B around the pin 2a in the arrow b direction and in the swivel lever 5 in the arrow c direction, and at the same time, the swivel lever is rotated. With the rotation of 5, the arrow d is moved along the guide rail 1 via the bracket 2.

That is, the chair B is rotated clockwise while moving downward in FIG. 1 and is displaced from the parallel state to the right angle state with respect to the wall surface A ₁ . Then, when it becomes a right angle state, the seat portion B ₂ can be lowered and used as a stool. The movement from the right angle state to the parallel state can be performed by rotating the motor 9 in the opposite direction to the above.

In the above-mentioned embodiment, the case of the chair for the vehicle has been described. However, as shown in FIG. 4, the bookcase C can be displaced in parallel (solid line) or at right angles (imaginary line) with respect to the wall surface. The same operation can be performed by mounting the same structure as described above.

In the embodiment described above, the power source is the motor 9, the rotational force is generated on the orbiting shaft 8 via the worm 10 and the worm gear 11, and the reaction force is used to rotate the object. Although the turning force of the turning lever 5 is generated, a lever / link mechanism for rotating the piston cylinder and the turning shaft may be used instead of the motor 9, the worm 10, and the worm gear 11.

Further, in the present embodiment, the case where the object is turned by about 90 degrees has been described, but the rotational movement angle of the object can be arbitrarily selected by bending the guide rail 1 by a predetermined angle on the plane. Further, in this embodiment, the turning center of the guide rail 1 and the turning lever 5 is set to the wall surface A ₁
However, it may be provided on a fixed surface such as a floor.

[0020]

As described above, according to the present invention, since the power source is arranged on the bottom surface of the object such as the chair and the bookcase, the working area can be extremely wide regardless of the fixed position of the object. Further, since the lever turning force for the rotational movement of the object uses the reaction force of the turning force of the object, the output of the turning and the required input for turning the object are substantially constant,
Therefore, there is an effect that it becomes possible to use an efficient small-capacity power generation source.
