Interlocking mechanism, interlocking sliding door, and slide rail

Technical field

The present invention relates to an interlocking mechanism for opening and closing a sliding door, and an interlocking sliding door using the interlocking mechanism. Also, the present invention relates to a slide rail used for the interlocking mechanism. Background art

As an example of the prior art, there is known an example of an interlocking mechanism described in Japanese Patent Application Laid-Open No. H11-104457. In this example, a pinion gear is rotatably mounted between a rack that moves at the same time as the main sliding door and a rack that is mounted on a fixed frame at a position vertically facing the rack. By engaging the shaft of the pinion gear with the driven sliding door, the pinion can obtain half the moving distance of the driven sliding door. This constitutes an interlocking mechanism that obtains a mechanism in which the driven sliding door interlocks with half the moving distance of the driven sliding door.

In the invention shown in the conventional example, the suspension mechanism and the fast-moving mechanism are independent to constitute the upper hanging door. For this reason, the interlocking mechanism needs to be installed separately from the suspension mechanism, which complicates the mechanism. It also has the problem of increasing costs.

In addition, since the engagement between the rack and the pinion gear is determined by the positional relationship between the rack installed on the driving sliding door and the rack installed on the fixed frame, high precision is required for the suspension mechanism. In addition, racks and pinion gears have the problem that they require cutting and are costly.

Next, as a first example of the slide rail, there is an example of a well-known slide rail shown in FIG. In this slide rail, the ball running surface is configured as a part of the outer member on the outside of two vertically arranged poles. The pole running surface is formed as a part of the inner member inside the vertically arranged poles. This slide rail is used where two rows of poles are arranged vertically.

Further, as a second example of the slide rail, there is an excellent example of the slide rail described in JP-A-2000-170435. In this example, the lower ball running surface is formed as a part of the outer member below the two rows of balls. In addition, by configuring the ball running surface that suppresses the upper part of the pole as a part of the inner member, slide It constitutes a rail and is used in a position where two rows of poles are lined up horizontally.

As a first example of the prior art, a slide rail shown in FIG. 8 is used in a direction in which a suspended moving body, for example, a sliding door is fixed to an inner member A2 and moved in the front and back directions in the figure. You. In this case, the weight of the sliding door is not applied to the upper pole and the outer member, but is supported by the lower rail surface of the outer member A1 via the inner member A2 and the lower ball A3. Had become. For this reason, there is a problem that the upper pole is not driven to rotate, and the movement of the ball retainer A4 holding the ball in alignment is likely to be unstable. In this example, the height in the vertical direction is large, so there is also a problem that a large space is required above the sliding door. When the part is installed downward, it will be supported by the horizontally aligned contact points of the inner member 2, the pole 3, and the air member 1, and the load applied to the inner member 2 will be reduced. This is the force that widens the opening of member 1. For this reason, since the inner member 2 falls, it also has a problem that it cannot withstand a large load.

As a second example of the related art, the slide rail shown in FIG. 10 is configured to use the opening of the first member 1 downward.

In this example, the load of the load fixed to the inner member A2 is the contact point A32 on both the left and right rail surfaces of the inner member A2, the pole A3, and the rail surface of the outer member A1. Since the contact point A31 is supported by the inner member A2, the load applied to the inner member A2 acts in a direction to lower the outer member A1. The problem of the slide rail shown in the first example of the prior art is supplemented by preventing the one member A2 from dropping and increasing the load resistance. However, when the sliding door is used as an example, it is assumed that a passenger or a transported baggage collides in a direction perpendicular to the sliding door moving direction. In the perpendicular direction, a load is applied via the spherical surface of the ball A3 in the direction perpendicular to the cylindrical surfaces of the inner member A2 and the outer member A1. Since the inner member A2 rides on the pole A3, there is a problem that the load capacity in the direction perpendicular to the sliding direction is small. Disclosure of the invention

An interlocking mechanism including a plurality of ball-shaped rotating bodies arranged in a longitudinal direction, and a driven member that grips the plurality of ball-shaped rotating bodies and moves along the guide member in the sliding direction together with a driven sliding door. is there.

For example, the interlocking mechanism according to the present invention includes two rows of ball-shaped rotating bodies that are arranged in a straight line at intervals, and an outer member (guide member) that is a fixed body that comes into contact with both rows and a movement that comes into contact with the rows. The inner member of the slide rail consisting of the inner member (the driving member) and the ball retainer (the driven member) that rotatably aligns and supports the pole-shaped rotating body, the inner member is engaged with the driving sliding door, The movement of the ball retainer causes the movement of the driven sliding door to be performed directly or indirectly.

Further, the interlocking mechanism of the present invention is a two-row ball-shaped rotator arranged in a straight line with an interval. A slide rail consisting of an outer member that is a fixed body that contacts the outside of both rows, an inner member that is a moving body that contacts the inside of the row, and a porous pole retainer that supports the pole-shaped rotating body in a freely rotatable manner. However, the inner member is directly or indirectly engaged with the driven sliding door, and the movement of the ball retainer causes the driven sliding door to move.

Further, the interlocking mechanism of the present invention is arranged such that the outer members of the two slide guides are positioned at the upper side and fixed to the opening of the building frame, and the inner member is positioned at the lower side to be free to move. The sliding door driven by the member is suspended and supported, and the sliding door driven by the inner member of the other slide guide is suspended and supported.

In addition, the interlocking mechanism of the present invention is arranged such that the outer members of the two slide guides are positioned below and fixed to the opening of the building frame, and the inner members are positioned above and free to move, while the inner members of the slide guides The sliding door that is driven is suspended and supported, and the sliding door that is driven by the inner member of the other slide guide is suspended and supported.

Further, the interlocking mechanism of the present invention is characterized in that the first member and the inner member of the two slide guides are horizontally opposed, the outer member is fixed to the opening of the building frame, and the inner member of the one slide guide is The main feature is that the main sliding door is suspended and supported, and the other sliding door that is driven by the inner member of the slide guide is suspended.

Further, in the interlocking mechanism of the present invention, the upper end of the driven sliding door is movably supported by the Kamoi, and the lower end of the driven sliding door is guided by a guide groove provided on the floor surface at a position facing the Kamoi. The main sliding door is pulled by the inner member of the slide guide, and the driven sliding door is pulled directly or indirectly by the pole retainer.

Next, in the case of the slide rail of the present invention, a pole running surface is formed by a part of the outer member, the ball is supported diagonally from below, and the ball running surface is opposed to the ball running surface via the ball. The upper pole running surface is formed as a part of the inner member, and a pole retainer is provided to align and hold two rows of poles. As a result, the load applied to the inner member is obliquely applied from the ball running surface of the inner member to the pole running surface of the outer member via the ball. This enables a greater load capacity to be obtained than when the pole row is used in a horizontal position.

As shown in FIG. 7, the slide rail is configured so that the pole running surface of the outer member extends from a horizontal position passing through the center of the pole to a vertical position passing through the center of the ball. In addition, by providing a structure in which the pole running surface of the inner member extends beyond the horizontal position passing through the center of the pole to the vertical position passing through the center of the ball, the horizontal load applied to the inner member can be reduced. It is designed to withstand the load.

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view showing an embodiment of an interlocking mechanism and an interlocking sliding door according to the present invention.

At the lower end (not shown) of the opening of the building frame, a ditch is provided in the sliding door moving direction, and two slide rails S 1 and S 2 are placed in a position inscribed in the ditch. The inner member 10 is located at a lower position, and the two sliding doors 11 1 and 1-2 are set apart from each other with a sufficient thickness and a clearance required for movement.

Sliding doors 1-1 and 1-2 are engaged with the lower ends of the inner members of the slide rails S1 and S2, so that the sliding doors 1-1 and 1-2 are suspended so as to be able to move linearly. The pole retainer 12 of the slide rail S 1 and the inner member 10-2 of the slide rail S 2 are engaged by the lever 13.

When a passer (not shown) is moved to pass by the driving sliding door 11-1, the inner member 10-1 which is engaged with the sliding door 1-1 is moved, and the pole bearing 11 is moved. Inner member 1 0—Move by 1 1 Z 2 movement amount. The ball retainer 12 _ 1 on which the pole bearing is aligned and supported moves by the same amount as the pole bearing moves.

The pole retainer 12 and the inner member 10-2 are engaged by the lever 13 As a result, the inner member 10_2 moves, and the driven sliding door 1-2 moves 1/2 of the moving distance of the main sliding door 1-1, thereby forming an interlocking mechanism and an interlocking sliding door.

According to the present invention, it is possible to use the two slide rails as a suspension mechanism for a sliding door, and at the same time, to provide the driven sliding door with an amount of movement of 1 to 2 of a driving sliding door as an interlocking mechanism.

In addition, the outer member of the slide rail can be directly installed at the gate or the opening of the building frame.Since it has a simple structure, the factors that cause failures are reduced compared to the conventional example. The configuration constitutes an interlocking mechanism or interlocking sliding door with low cost and low risk of failure.

FIG. 2 is a side view showing another embodiment of the present invention. In the present embodiment, an example is shown in which the outer member of the slide rail is arranged below and the inner member is arranged above.

The frame 8 has a C-shape, and is installed at the lower end of the opening of the building frame or the lower part of the Kamoi, with the opening facing downward. The upper end of the support that protrudes horizontally from the opening contacts the lower surface of the outer members of the slide rails S1 and S2, and has the strength to support the weight of the sliding doors 1-1 and 1-2 and the weight of the two slide rails. It is installed at the lower end of the opening of the building frame. A C-shaped bracket 21 is fixed from the upper end of the inner members 10-1, 10-2 of the slide rails S 1 and S 2, and a driving sliding door 11 and a driven sliding door 11 are located at the lower portion of the bracket. 2 is suspended and engaged. The ball retainer 12 and the inner member 10-2 are connected by the lever 13.

As the main sliding door 1 1 1 moves, the inner member 1 0 1 connected by the main sliding door 1 1 1 and the bracket 2 1 moves, and the ball retainer 1 2 moves the moving amount of the main sliding door 1 1 1. Move 1/2 the distance.

Since the ball retainer 12 is connected to the inner member 10-2 by the lever 13, the driven sliding doors 1 and 2 are linked at a value of 移動 of the moving distance of the driving sliding door.

According to the present invention, the weight of the sliding door is applied to the inner member, and the weight is The load is applied to the outer member via the ring, which is a force that expands the opening of the outer member. This has the effect of increasing the load-bearing capacity and making it possible to suspend a heavier sliding door.

FIG. 3 is a side view showing another embodiment of the present invention. In the present embodiment, an example is shown in which the slide rails S l and S 2 are arranged such that an inner member and an outer member are horizontally arranged.

The frame 8 has a U-shape, with the opening facing downward, and the upper end is set at the opening of the building frame or the lower part of the Kamoi. Because of the frame 8, the outer members of the slide rails S l and S 2 are fixed to the inner surface of the U-shaped hanging part. Since the fixing method is not the object of the present invention, it is omitted.

The main sliding door 11-1 and the driven sliding door 1-2 are suspended from the inner members 10-1 and 10-2 of the slide rails S l and S 2 by brackets 21. Ball retainer 12 is connected to inner member 10-2 by lever 13.

As the main sliding door 1-1 moves, the inner member 10-1 moves, the pole retainer 12 moves 1 Z 2 of the moving distance of the main sliding door 1-1, and the pole retainer 12 and the lever 13 move. The member 1 0-2 connected via the moves, and the driven sliding doors 1-2 can be interlocked with each other by a moving amount of 2 of the moving amount of the driven sliding doors 1-1.

According to the present invention, the weight of the sliding door is applied to the outer member via the bracket, the inner member, and the pole bearing, and the load becomes a force for expanding the opening of the outer member. It does not fall from the part, and has the effect of increasing the load resistance compared to the method in which the inner member is directed downward.

FIG. 4 is a side view showing another embodiment of the present invention. In this embodiment, an example is shown in which one slide rail is installed above the driving door, a door roller is installed below the sliding door, and a guide rail is installed on the floor.

Frame 8 has an E-shape, with two side-by-side openings arranged below and an upper part It is installed at the lower end of the body or under the Kamoi.

The slide rail S1 is framed with the outer sliding member 9-1 facing upward and the inner member 10-1 facing downward with a distance above the driving sliding door 1-1 and not in contact with the upper end of the driving sliding door 1-1. 8 is installed at the bottom of one side opening.

The driven sliding doors 1 and 1 and the driven sliding doors 1 and 2 are provided with a door roller 42 at a lower portion, a guide rail 43 at an upper floor, and the door roller 42 is movably installed by being guided by the guide rail. ing. The driving sliding door 1-1 upper portion is engaged by the bracket 21 with the inner member 10-1 of the slide rail S1.

A roller rotatable in the horizontal direction is installed on the upper part of the driven sliding door. The roller is disposed inside the other opening of the frame 8, and when the driven sliding doors 1-2 move, the frame 8 serves as an upper guide rail of the driven sliding door. 4 1 can be guided and the driven sliding door 1-1 moves without falling.

When the driving sliding door 1-1 moves and the inner member 1 0-1 moves, the ball retainer 12 moves by the moving distance of 1 Z 2 of the driving sliding door 1-1, and the ball retainer 12 and the lever are moved. The roller 41 and the driven sliding door 1-2 that are engaged by the one 13 move the moving distance of the driven sliding door 12 to form an interlocking mechanism.

ADVANTAGE OF THE INVENTION According to this invention, a sliding door weight is supported by a door roller, there is no load on a slide rail, and it has the advantage that cost can be reduced by reducing the required rigidity of a slide rail. Another advantage is that the interlocking sliding door can be configured even if the lower end of the Kamoi-to-frame opening does not have the strength to support the sliding door weight due to the construction method of the building. In this example, an example is shown in which a roller is used above the driven sliding door. However, even if there is no roller and the sliding door 1-2 slides on the frame 8, this does not depart from the present invention.

The principle of the present invention will be described with reference to FIG. The moving part 52 is disposed in contact with the upper part of the pole 53 that is freely rotatably moved in contact with the fixed part 51 and faces the fixed part. Assuming that the radius of the pole 53 is R, the rotation speed of the ball 53 is N1, and the moving distance of the center of the ball 53 with respect to the fixed portion 51 is D1, D1 has a circumference 2 TTR and a rotation speed N By multiplying by 1, D 1 = 27 t R · (N 1). On the other hand, assuming that the moving distance of the moving part 5 2 with respect to the fixed part 51 is D 2, D 2 = 2 TTR · (N 1) + 2 π R · (Ν 1) = 47C R · (N 1). Therefore, the moving amount D2 of the moving portion 52-1 is twice as large as D1.

The interlocking mechanism of the present invention may be used for semi-automatic operation by providing a motor (drive means) for automatically moving the driving sliding door along the outer member 9. In addition, for example, by tilting the hanging slide rail that constitutes the interlocking mechanism with the sliding door's tip downward, the gravity of the sliding door's own weight can be used to automatically open the manually opened sliding door. It can be used as a semi-automatic sliding door by adding this closing mechanism.

Next, an embodiment of the slide rail of the present invention will be described with reference to FIG.

FIG. 7 is a sectional view showing one embodiment of the slide rail A according to the present invention.

The slide rail A according to the present invention includes an outer member A 1 as a fixed rail, an inner member A 2 as a movable rail, a plurality of balls A 3, and a pole retainer A 4 for aligning and holding the balls A 3. Be composed. The outer member A1 has an arc shape having a curvature smaller than the curvature of the pole A3 in the vicinity of the tip end thereof, and forms two rows of ball running surfaces that support the ball A3 from obliquely below.

The inner member A 2 has an arc shape having a curvature smaller than the curvature of the ball 3 near the tip inside the outer member A 1, and two rows of diagonally upper pole running on the lower surface of the arc shape. Forming a surface. The two rows of poles A3 are aligned and held by ball retainers A4 having circular holes formed at substantially equal intervals.

The plurality of balls A3 are aligned in two rows in a straight line, and are rotated and driven by the friction of the inner member A2 at the contact point A7 with the running surface by the movement of the inner member A2. By rotating on the contact point A8 on the pole running surface, the inner member A2 receives a small rolling friction resistance as compared with the sliding friction and moves linearly.

The pole running surface formed on the outer member A1 is an arc that extends from the position above the horizontal line A14 passing through the center of the pole A3 to the inside of the position of the vertical line A6 passing through the center of the pole A3. The pole running surface formed by the inner member A2 extends from a position below the horizontal line A14 passing through the center of the pole A3 to outside the vertical line A6 passing through the center of the pole A3. Form an arc. In the example in which the slide rail is used for a sliding door, the outer member 1 is provided with a hole at the center thereof, and is fixed by a port 13 through the hole (for example, directly at the lower end of the opening of the building frame or at the lower end thereof). It is fixed to the provided gate. A hole (not shown) is provided in the approximate center of the inner member A2, and the inner member A2 is fixed to an upper part of a sliding door (not shown) through the hole.

As described above, since the inner member A2 is movable, the sliding door can be moved by a passerby. The weight of the sliding door is applied to the contact point A7 between the inner member A2 and the ball A3 and the contact point A8 between the outer member A1 and the pole A3 via the ball A3, and is supported by the outer member A1. The weight of the sliding door is such that the inner member A2, the pole A3 and the outer member A1 are always in contact on the inclined line A5, and the pole running surface of the inner member A2 is at the contact point A7 from both outsides. It is supported by receiving a force diagonally inward. Sliding doors may collide with passers-by or luggage, but the impact on the sliding doors is a force that moves the inner member A2 in a direction perpendicular to the traveling direction. As a reaction from the outer member A1 due to the weight of the sliding door, a force is applied to the center from both sides, so if the force received in the horizontal direction is small, it becomes a force that resists horizontal movement and is stable. Running is obtained.

When the force received in the horizontal direction is large, the intersection A10 between the horizontal line A14 passing through the center of the ball A3 and the pole running surface of the inner member A2 and the pole A3 via the pole A3, the ball member A1 A force is applied to the outer member A1 at an intersection A9 between the outer member A1 and the horizontal line A14, and the horizontal force can be supported, thereby providing a structure capable of withstanding a large force.

In addition, the intersection of the pole running surface of the inner member A2 and the vertical line A6 passing through the center of the pole also applies to a large sliding door weight or a large vertical force due to a vibration such as a collision with the sliding door or an earthquake other than the sliding door weight. The force is transmitted to the intersection A11 between the outer member A1 and the vertical line A6 via A12 and the pole A3, and can be supported by the outer member A1. Offering structure.

The ball running surfaces of the inner member A2 and the outer member A1 have been described on the assumption that the arc has a curvature smaller than the curvature of the pole A3. It is possible to configure even a partial straight line.

The pole retainer A4 has been described as an integral structure, but the two rows of porous parts must be separated and connected at the center, or the center must be connected by a separate joining member. This is also a method for facilitating the production of the present invention.

The slide rail according to the present invention shown in FIG. 8 has a drawback in the prior art in that, when the opening of the outer member A1 is used with the opening directed downward, the downward load applied to the inner member A2 is reduced. The load is equally applied diagonally to the rails of the inner member A and the rail of the first member A1 via the two rows of balls A3, and can withstand the load applied to the inner member A2.

In addition, the inner member A2 and the outer member A1 face each other at the contact points A9 and A10 via the ball A3 against the load applied perpendicularly to the traveling direction of the inner member A2. The purpose of the present invention is to provide a slide rail capable of obtaining a large load capacity.

As described above, the slide rail of the present invention has been described, but is not implemented in the above-described embodiment. For example, the shape of the hole holding the pole A3 is not limited to a circle, but may be a substantially circular or elliptical shape. The pole running surface formed on the outer member A 1 extends from a position above a horizontal line A 14 passing through the center of the ball A 3 to an inside of a vertical line A 6 passing through the center of the pole A 3. The present invention is not limited to this, and it may be near the position of the vertical line A6. Industrial applicability

With the interlocking mechanism and the interlocking sliding door of the present invention, an inexpensive interlocking mechanism can be provided. It also has the feature that the occurrence of failures can be significantly reduced by a simple mechanism.

Next, according to the slide rail of the present invention, the load applied to the inner member is obliquely externally applied to the pole running surface formed on the inner member and the pole running surface formed on the outer member via the row of balls. Loaded toward For this reason, it is possible to obtain a stronger load resistance as compared with the slide rail shown in the first example of the conventional technology. Also, the ball running surface formed on the inner member extends from the horizontal line passing through the center of the pole to beyond the vertical line passing through the center of the pole, and the pole running surface formed on the outer member moves along the center of the ball. The horizontal line passes through the vertical line passing through the center of the ball. This makes it possible to obtain a larger lateral load than the slide rail shown in the second example of the prior art.

The load applied to the inner member is evenly applied to the outer member via a pole. As a result, a stable load is applied to the pole, making it possible for the pole to generate stable rotation. By stabilizing the rotation of the pole, the stability of the movement of the pole retainer is improved and the movement of the inner member is more stable.
