Description

[Detailed description of the invention] A rail device installed on or along stairs and used for chairlits, etc. The present invention provides a railing for use in chairlits, etc., which is installed on or along stairs. This rail device is installed on or along a staircase. This is a rail device used for chairlift I, etc., which has a horizontal member and a vertical member. with a rail section along the direction of movement and a rail section that is attached to a fixed position. and a moving rail end that is a lower end of the section, and the moving rail end is in the moving direction. a position where the movable rail end portion is fixed along the rail portion and a position where the movable rail end portion is fixed. Horizontal section along the direction of travel, limited by the lower end of the rail section to which it is attached the end of the moving rail between a position forming a substantially right angle with the material and a substantially perpendicular plane; The part rotates.

Installing the end of the moving rail so that it can rotate sideways means This rail is intended to be the least obtrusive at the bottom of the rung. . In fact, the position of the floor in front of the stairs with the desired means of chairlit Extend the rail some distance further from the end of the stair to If the staircase ends in a hall, as is often the case, If the rail runs across the stairs or ends in a hallway that extends across the stairs, If it extends beyond the end of the column, it becomes an inconvenient nuisance. stairs like this Configuring the protruding rail as a moving rail end that rotates sideways. This should reduce possible failures.

However, in order to form such a rotating rail structure, it takes many (issues) into consideration. must be The rail has a function to guide chair lit etc. Functions cannot be ignored. This means that the guide surface may This means that it must not be affected by the hinge fittings. Furthermore, this fixation The chairlit, etc. moves smoothly from the rail section to the moving rail section, but there is nothing wrong with it. It is necessary for forces and moments to be transmitted between the two without any physical influence. Ru. In known rail devices of the type mentioned above, arrangements are made to suit the purpose. so that the end of the movable rail rotates to the right or left relative to the fixed rail attached to it. It is configured. Therefore, the guide surface differences and force transfer problems that arise with this method For this reason, a hinge axis that runs approximately vertically is a good solution.

However, the end of the moving rail does not rotate or turn to the right or left. It's also strange. The end of the moving rail rotates to the right or to the left. depending on whether the rail device is installed on the right or left side of the staircase. Stairs can also become an obstacle or hindrance to daily use. With this kind of configuration For example, the rail device can rotate the end of the moving rail to the right or left when it is mounted on a wall or Only in special cases where it is difficult to adopt because it is obstructed by the presence of a door. will be needed.

The present invention is designed for use when the end of the moving rail is in a position where it rotates or pivots in the right, left, or lateral direction. However, stairs rarely get in the way of daily use, and may exist. These pivoting and rotational movements are not obstructed by doors or walls. It forms the end of the moving rail and can be moved with an appropriate amount of force, and the movement of the guide surface is maintained smoothly. The purpose is to make it possible to hold.

According to the invention, the above object is achieved by attaching the end of the moving rail to a fixed position. from the position where it touches the rail part in the same direction and facing upwards. This is solved by configuring it to pivot to a vertical position in contact with the lower end.

These features allow the end of the moving rail to tilt/swivel relative to the fixed rail. Then it will be in an upright position. There are no obstructions in this direction, and Space that must be moved so that the air lit can reach the floor in front of the stairs There is also. Additionally, this tilting/swivel movement occurs when the end of the moving rail pivots downward. is in contact with the end of the fixed rail part, and at that time, the desired force is applied and the guide surface is also moved. It has the effect of being accomplished smoothly.

According to the invention, the conventional means of turning to the right or left need not be taken into account. Therefore, the configuration of the rail device will become more common, and this rail device It doesn't matter whether it is installed on the left side or the right side of the stairs, the same structural member can be installed. Can be used. For this reason, costs related to product manufacturing and parts inventory management will decrease as well as Business operations can be simplified.

Further, according to a preferred embodiment of the present invention, the movable rail end portion is in contact with the fixed rail portion. When the moving rail is in position 1, the end of this moving rail is spaced apart from the lower end of the fixed rail. This moving rail is moved to a desired vertical position by means of a control means and a moving means. Provided with at least one hinge axis capable of transmitting movement of the end The end of the fixed rail section Therefore, it acts as a second pressing or supporting surface for the end of the moving rail. death However, two hinge shafts are provided that are spaced apart in the vertical direction at the end of the moving rail, and at least one of the hinge shafts is provided with a desired movement by the control means and the movement means. It is preferable if it can be communicated. This simple method allows you to move Allows the end of the rail to move in a step-by-step and precisely controlled manner during its movement I have to.

Both or one of the hinge axes may have a bin or jig guided in the cam track groove. The journal axis is configured. However, the hinge axis is The other end of this pivot lever connects to two separate fixed positions through a hinge shaft. and at least one of the pivot levers is connected to one of the control means and one of the moving means. In this way, the end of the moving rail can pivot up and down. is a simple mechanism that rotates one of the hinge shafts connected to the other end of the swivel lever. (e.g., a power source that can be powered from the edge of a staircase or a chairlit) (by a dynamic motor). Naturally, the end of the moving rail moves up and down. The pivoting movement can be performed manually or motor-driven by the user.

According to a further preferred embodiment of the invention, one of the hinge axes is located at the lower end of the end of the moving rail. The pivot lever provided near the end and linked to the other hinge shaft at the end of the moving rail is , so that it is rotatably driven by a motor in a fixed position. drive uni The piece can be placed below the stair, generally the fixed rail section, while the moving rail end is preferably in a downwardly rotated position, or at its two end points. It is supported by Move from a tilted position to a generally vertical position or vice versa In order to tilt/swivel the rail end, the movable rail end must be connected to the fixed rail. When the movable rail is in a position where it is in contact with the The pivot lever that interlocks with the hinge shaft extends approximately horizontally and is located at the end of the moving rail. A swing lever that is linked to a hinge shaft is located between the swing lever and the end of the movable rail. A more acute angle is formed with the pivot lever linked to the hinge shaft installed near the movable lever. When the end of the roll is in the other end position, the pivot lever extends generally vertically. It is growing. Due to these features, when in the two end positions, the end of the moving rail is Can be moved to a stable horizontal or vertical position held by gravity . On the other hand, another swivel lever that is not parallel to the lower swivel lever While the end of the wheel is pivoted, it is provided with a tilting movement.

According to a further embodiment of the invention, the The stability of the swing lever is determined by the hinge shaft at the lower end of the moving rail end. It is located in contact with the fixed rail part and is flush with the hinge axis of the other swing lever. It becomes optimal when The pivot lever thus connected to the lower end of the moving rail end cannot be rotated any further downwards, and the lowest position of the end of the moving rail is determined.

According to a further embodiment of the invention, the ends of the moving rail are connected to at least one end thereof. It can be stabilized in position, and at least in the same direction and above the fixed rail part. When a spring is provided to assist in turning in the direction, both end positions It supports the two maintenance states in the position and balances the tilting/turning motion. The process can be configured to be performed in stages. One way to do this is, for example, using a spring. A pivot whose one end is interlocked with a hinge shaft provided near the lower end of the end of the moving rail. It is attached to the edge of the lever, around the middle of the two hinge shafts, and the other end of the spring is Near the hinge shaft connected in a fixed position and not connected to other pivot levers. It is composed of

In this way, the springs can pull the end of the moving rail toward its two end positions. while the end of the moving rail is configured to move from the downwardly pivoted end position. After being released, the spring helps the end of the moving rail pivot upward and move downward. It's preventing me from doing that. This is also an advantage when manual operation is chosen.

According to yet another embodiment of the invention, the moving rail end and the fixed rail portion are in contact with each other. At the position where they face each other, the interface between the two extends generally in the vertical direction. The rail is tilted. Because it is slanted, the generally vertical interface is such that the end of the moving rail is on top of the fixed rail. This means that it is supported by the same structure, which optimizes the transfer of force. similar In this case, the tilt/swivel movement is started and completed without any problems. Rotation towards the top or When in the swiveled position, this generally vertical end of the travel rail also It is in a state where it is leaning against a vertical support surface. Furthermore, the end of the moving rail For example, a hook-shaped web may be configured to lock in its two end positions. By using the This can be achieved by locking dynamically.

An embodiment of the rail device according to the invention will be described below together with the reference numerals shown in the accompanying drawings. Examples are given below.

FIG. 1 is a plan view of a chairlit equipped with a rail device according to the present invention. Ranked below Alit! The position of the rail device is indicated by a thick solid line.

Figure 2 is a front view of Figure 1, showing the rail device installed on the back side of the chairlit. The position, especially the position of the end of the moving rail that has rotated or pivoted upward, is indicated here by a thick solid line. It is shown.

Figure 3 shows the plane of the rail device in the position where the end of the moving rail is rotated or pivoted upwards. It is a diagram.

FIG. 4 is a front view of FIG. 3.

1 and 2 schematically show a chairlit l moving along a rail device 2. It is something that The means for guiding and moving the chairlit 1 are related to the subject matter of the invention. Therefore, it is not shown in the diagram or described in detail.

The rail device 2 has a rail part 5 fixed to the wall 3 and/or the stairs 4. The fixed rail portion 5 can be rotated or pivoted upward as shown in FIGS. 1 and 2. It is connected to the rotating moving rail end 6 at a downwardly rotated or pivoted position. The mating moving rail end 6 extends together with the fixed rail part 5, and the two are in contact with each other. It becomes. The moving rail end 6 is basically downward toward the floor 7 in front of the stairs 4. The chairlit 1 user can get off the chair without any problem. I am now able to do this.

As best shown in FIG. 1, the moving rail end 6 is in a downwardly rotated position. -The door 8 cannot be opened even by the means shown in Figure 3. . Even when the door 8 is a front door, the direction of rotation is the same as usual. if, If the moving rail end 6 can be pivoted about a vertical axis in the direction of the door 8 If so, it will not be a solution to this problem. This is because the room in question does not exist. .

In situations where problem rooms exist, such as toilets, storage rooms, or closets. Doors that lead to other rooms, such as the one above, are usually located next to stairs 4. Transfer In the means for horizontally rotating the movable rail end 6, the movable rail end 6 It will be in a position that crosses in front of the stairs 4, which will impede daily use. Therefore, According to the present invention, as shown in FIGS. 3 and 4, the end portion 6 of the moving rail is directed upwardly. The purpose is to rotate it in the backward direction.

Up to its end position, the moving rail end 6 engages both the pivoting lever 9 and the pivoting lever 10. They are connected by hinge means, and each of the pivot levers 9 and 10 is connected to either side of the rail. It consists of two lever arms on either side. One of the turning levers 9 The end is connected to the lower end of the moving rail end 6 via the hinge shaft 11, and is pivotable. The other end of the lever 9 is connected to a support structure 13 fixed to the stairs 4 via a hinge shaft 12. has been done. The pivoting lever IO is attached to the support structure 13 via the hinge shaft 14 at its end. The other end is connected to the moving rail end 6 via the hinge shaft 15. There is.

In order not to affect the guide surface of the moving rail end 6, the hinge shafts 11 and 15 are moved. A member 1 that is not directly connected to the moving rail end 6 and is fixed to the moving rail end 6 6.17. When the movable rail end 6 is turned downward, The positional relationship of the hinge shafts 11, 14, and 15 is basically arranged in a straight line. Therefore, the pivot lever 9 cannot be pivoted further downward from the position shown in Fig. 2. Scratches can be removed by the moving rail end 6, making the lift guide stable and its position stable. It means that you can support it.

This stable position is also determined by the interface between the fixed rail section 5 and the moving rail end 6. 18 in an essentially vertical position. Therefore, lift chair When loaded by 1, the moving rail end 6 located on the boundary surface 18 becomes fixed rail It is supported by the roll portion 5. Boundary surface 1 is fixed with moving rail end 6 It can be understood that it is continuous to the member 17 fixed to both of the rail parts 5. Good morning.

The motor 19 moves the moving rail end 6 from the position shown in FIG. 2 to the position shown in FIG. Rank! It is provided for pivoting upward towards or vice versa. In other words, This motor 19 is employed to rotate the hinge shaft 14. motor 19 Its function is arranged so that it can be controlled from the end of the staircase or lift chair 1. There is.

If the end portion 6 of the moving rail rotates or pivots upward, the It is shown. As clearly shown in Figure 3, the door 8 in this position is in the way. The door can be opened without becoming a problem, and the use of stairs 4 is actually not obstructed. . If there is a door next to the stairs, the moving rail end 6 is in an upwardly rotated position. The opening of the Mesono door is unobstructed.

In the position shown in FIG. 4, the moving rail end 6 is at the lower end of the fixed rail section 6 It is in a stable position because it is leaning against the other side. moving rail The roll end 6 performs both turning and tilting movement while moving. For example, hooks on both the end of the moving rail and the fixed rail can be used to lock the rail during movement. This can be accomplished relatively easily by providing a shaped web (not shown). In other words, this so that both webs automatically engage each other at the end of the tilting/swivel movement. There is. Such a locking naturally also takes place in a rotated or pivoted position.

In the embodiment shown in the figure, the rail device is located on the left side of the staircase 4 when looking upwards. It is set in. As is clear from the drawings, especially the plan view, the rail device 2 is a staircase 4, and can be configured by simple means, but the motor Only the data 19 is placed on the other side.

The stability in the two end positions is determined by the mounting on the pivot lever near the hinge axis 14. between position 22 and mounting position 23 on the swivel lever 9, the telescopic bar shown in the figure This can be improved by expanding and contracting the hole 21. in the downwardly rotated position shown in Figure 2. In this case, the spring 21 has the hinge axes 11.14, 1.5 in a straight line, and the spring 21 is 21 has already passed its maximum extended position, so it has no effect at all. .

When the spring 21 moves from this position, it stretches a little further, then contracts and rotates upward. It assists in the movements that you do. In the upwardly rotated state shown in Figure 4, The spring 21 is in its most compressed position, and this upwardly rotated position is well stable. are doing. Furthermore, while the moving rail end 6 is moving downward, the wing 21 is moved by gravity. Brake the pivoting movement that is encouraged. In this way, the telescopic spring 21 is connected to the moving rail end 6 is stabilized at its two end points, and the movement while moving between the two end points. It also stabilizes the balance. This applies both manually and with motors. Even so, it is an advantage.

The embodiments of the rail device operated by the motor have been described above. Moving rail end 6 Move it to the rotated position upwards as well by motor instead of manually 0 In the event of a malfunction, such as a failure of the main power supply, the lift can be stopped, A safe machine is then installed that allows the lift to be moved manually along the guide. actuate the mechanism, and then manually move the moving rail end 6 to a downward rotating or pivoting position. For manual operation, hold the end of the moving rail directly, as shown in the example below. This prevents your hands from getting dirty with lubricants, etc., and also prevents hand grips and handles from getting dirty. for example near the interface 18 between the fixed rail part 5 and the moving rail end 6. It can be provided on a nearby member 17.

Many modifications and changes may be made within the scope of the invention.

For example, if a lever fulcrum 12 is provided on the first step of the stairs 4, the end that rotates upward will be can be moved completely into the stair tread (i.e. just inside line 20 in Figure 3). During turning/tilting, the hinge axis 11.15 follows a predetermined trajectory. Instead of using the pivot lever 9.10 to draw these trajectories or these trajectories Slide or rotate the hinge shaft (or one of the traces) within the guide groove This can be made constant. At the position shown in Figure 2, the end of the moving rail 6 can support the fixed rail part 5, so if the guide support of the chairlit 1 If the retainer can be moved beyond the hinge axis at the end of the moving rail, the lock is provided near the boundary surface 18, the pivot lever is not used in principle. One is enough. Therefore, considering stability, at least the moving rail end 6 It is desirable to have a double connection. Promotes stability at the end of travel position and In order to facilitate tilting and turning movement, a torsion spring or gas pressure can be used instead of the telescopic spring 21. A compression spring may also be provided.
