Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rebound preventing device for preventing rebound of a sliding door and the like, and a rebound preventing object such as a sliding door.

[0002]

2. Description of the Related Art There are cases where a door such as an entrance or a room, a sash, or the like is provided with a sliding door that opens and closes to the left and right by pushing and pulling. Such sliding doors are widely used, probably because of the small area of buildings in Japan and the fact that there are many houses that cannot be opened and closed so much. In such a sliding door, a roller is provided on the lower bottom,
There are some which are not provided with rollers.

In the former case, a smoothly rotatable roller is provided on the lower bottom portion of the sliding door, and this roller is fitted in the rail. Therefore, when closing the sliding door, the roller slides on the rail just by pulling the sliding door,
It is possible to open and close the sliding door with little resistance. Further, when closing the sliding door, the sliding door is pulled and brought into contact with the door stopper. It locks doors and sashes. The latter case is different from the former in that the resistance at the time of opening and closing is large, but other operations are the same.

In recent years, most sliding doors with rollers are formed of a frame made of aluminum or the like and a glass having a large thickness, and are often heavy in weight. However, since the resistance generated between the roller and the rail is small in spite of the weight of the sliding door, it is possible to smoothly slide the sliding door to lock it.

[0005]

By the way, when the sliding door with the roller is pulled vigorously to be closed, the sliding door may collide with the door stop, and the recoil may cause a rebound. Particularly in recent sliding doors, perhaps due to the small resistance between the rollers and the rails, even though the sliding door is heavy, it rebounds. This is also due to the fact that when the resistance between the roller and the rail is small, once the sliding door travels on the rail, the sliding door collides with the door stop without losing its momentum.

For this reason, even when the sliding door is slowly closed, a sharp bounce may occur. For this reason, for example, in cold seasons such as winter, it is necessary to close the sliding door securely in order to prevent drafts, but in order to prevent such rebound and to close the sliding door securely, it is necessary to manually close the sliding door. You will be forced to perform actions such as pressing and closing the sliding door that has rebounded. In addition, in order to prevent rebounding, the operator may pull the sliding door while keeping his / her hand on the sliding door and push the sliding door toward the sliding door even if the sliding door contacts the sliding door.

That is, when closing the sliding door as described above, it is not enough to simply run the sliding door on the rail, and it is necessary to close the sliding door by touching the sliding door again after hitting the door. For this reason, when it is necessary to go out in a hurry, it may be frustrating, and it takes time and effort to close the sliding door.

At present, there are some fasteners that use magnets, springs or the like, or devices that are so-called catches to prevent the sliding door from rebounding. However, if it is attempted to prevent the sliding door from rebounding with such a fastener or catch, it is unavoidable to provide a considerably strong holding force between the sliding door and the door stop. When a strong holding force is applied between the sliding door and the door stop in this way, the resistance when opening and closing the sliding door becomes large, which is inconvenient in practical use.

As described above, even if the sliding door is closed, the sliding door does not bounce due to the reaction due to the collision with the door stop, and it is desired to provide the sliding door with a means that can be easily opened when the sliding door is reopened. ing.

The present invention has been made in view of the above circumstances, and its object is to prevent the sliding door from bouncing even if it collides with a door stop, and to make sure even if a hand is released from the sliding door. An object of the present invention is to provide a bounce prevention device and a bounce prevention object capable of closing a sliding door.

[0011]

In order to achieve the above-mentioned object, the present invention provides a rebound preventing device for preventing rebound due to reaction of a collision when one member collides with the other member. And a rotating member that is provided on the moving body and is rotatable by a predetermined angle, and that is provided on the moving body, moves when the moving body collides, and restricts the rotation of the rotating member at the moving position. And a spherical member
When a collision occurs between the regulating member and the other member or a fixed body attached to the side of the regulating member, and the one member and the other member collide with each other, after being inserted into the moving body and rotating the rotating member, The movable member and the fixed member are connected to each other by being fitted to the rotating member and being restricted from rotating by the restricting member, and the restricting member returns to its original position to rotate. an engaging member moving member is a decoupling state and a moving body and the fixed body becomes rotatable, one of the mobile
When the member of
It is installed at the existing position, and it travels when the restriction member collides.
A plurality of collision walls whose direction is changed ,
Between the collision walls of the control member, the regulating member must repeatedly collide multiple times.
It is obtained by the.

Thus, when the engaging member is inserted into the movable body, the rotating member is rotated and the rotating member and the engaging member are fitted together. After this fitting, or when one member collides with the other member at the same time as the rotation,
Due to the collision, the restricting member moves to a position that restricts the rotation of the rotating member. Thereby, you can not rotate the rotating member to return to the original position, even if an attempt is spaced one member from the other member by a reaction of the collision impact between the one member and the other member, spaced not It will be possible.
Therefore, it is possible to prevent a gap from being formed between one member and the other member. Also, even if there is a recoil due to a collision between one member and the other member, one member does not open.Therefore, in order to eliminate the clearance due to the recoil, pull one member to the other member without releasing your hand, It is released from the work of closing one of the members. This improves convenience when closing one member such as a sliding door.

Also, when one member collides with the other member
In this case, the restricting member, which is a spherical member, collides with the collision wall. So
Then, the regulating member may repeatedly collide between the collision walls.
However, compared to the case where no collision occurs, multiple

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. Of these, FIG. 1 is a side sectional view showing the configuration of the bounce prevention device 10 of the present invention, and FIG. 2 is a plan view showing the configuration of the bounce prevention device 10 of FIG. It is a cross-sectional view taken along the line X-. In these figures, the bounce prevention device 1
0 is one member and a sliding door 1 as a rebound preventing material.
3 and a fixed body 12 attached to a door stop 14 as the other member.

In practice, the fixed body 12 may be attached and fixed to the side of the door stop 14, but in such a case, it can be regarded as the same as the case where the fixed body 12 is attached and fixed to the door stop 14. In the description, the door stop 14 and the fixed body 1
The case of attaching 2 will be described.

Of these, the fixed body 12 is attached to a stationary door stop 14 (a position where the sliding door 13 is displaced from the collision portion and fitted with the moving body 11), and its constitution is the mounting plate 20 and the engaging member. It is composed of an engaging bar 21 as a joining member. Of these, the mounting plate 2
A part of 0 is bent and formed, and a pedestal portion 22 in which the central portion in the longitudinal direction is raised more than both ends due to this bending is provided.

A screw 2 for mounting and fixing the above-mentioned engagement bar 21 to the mounting plate 20 is provided at the center of the pedestal portion 22.
A mounting hole 23 for inserting 4 is formed. Therefore, when the engagement bar 21 is attached and fixed to the attachment plate 20, the engagement bar 21 is brought into contact with the raised side of the pedestal portion 22. After that, the screw 24 is inserted into the mounting hole 23 from the back surface side of the pedestal portion 22. In addition, from one end side of the engaging bar 21, the screw hole 2
5 is threaded. Therefore, by aligning the screw 24 inserted in the mounting hole 23 with the screw hole 25 and screwing the screw 24, the engagement bar 21 is fixedly attached to the mounting plate 20.

Both ends of the mounting plate 20 have a door stop 14
Is a contact portion 26 for mounting and fixing. It should be noted that the mounting and fixing between the mounting plate 20 and the door stop 14 can be performed by using various means or methods such as a screw, an adhesive, or a double-sided tape. Per unit 14
On the other hand, when the mounting plate 20 is mounted and fixed with screws, a through hole (not shown) may be formed in the contact portion.

The main body of the engaging bar 21 is a quadrangular prism, and as shown in FIG. 1, a concave engaging portion 27 is formed in the middle of the main body. The concave engaging portion 27 engages with a claw portion 47 described later when the engaging bar 21 is inserted inside the moving body 11 described later. The concave engagement portion 27 is formed in a substantially triangular groove shape when viewed from the side. Therefore, the wall surface 27a of the concave engaging portion 27
The claw portion 47 is formed at an angle capable of sliding along the (wall surface 27b).

That is, in FIG. 1, assuming that the angles formed by the wall surfaces 27a and 27b of the concave engaging portion 27 with respect to the center line L are θ1 and θ2, θ1 and θ2 are substantially equal, and the angles are acute angles. Is formed. In practice, the wall surfaces 27a and 27b are set so that θ1 and θ2 are close to 45 degrees in order to allow the claw portion 47 to slide smoothly. However, any other acute angle may of course be used. The engaging bar 21 has a quadrangular pyramid-shaped pointed portion 21a at its tip end side.

The moving body 11 into which the engaging bar 21 is inserted
2 is attached to the side of the sliding door 13, such as a frame of a sash, as shown in FIGS. The moving body 11 is entirely covered by the casing 30. As shown in FIG. 2, the casing 30 includes a front case 30a on the side of the fixed body 14, two side cases 30b and 30c, and both side cases 30b and 30c.
It is composed of an inner case 30d sandwiched by 30c and has a space portion 31 of a predetermined size therein.
In this embodiment, both side cases 30b, 30
c is transparent.

Here, in the casing 30, as shown in FIG. 3, a portion facing the fixed body 12 and communicating with the bar engaging portion 32 is cut out to form an opening 30g. . Thereby, the engagement bar 21 can be inserted into the bar engagement portion 32. In addition,
The opening 30g is larger than the vertical and horizontal lengths of the engaging bar 21 in FIG. Thereby, it is possible to absorb the mounting error and the secular change of the sliding door 13 and the door stop 14.

On the lower side of the bar engaging portion 32,
A rotation space 33 is provided in which a rotation claw 45 described later is attached so as to be rotatable by a predetermined angle. In this rotation space portion 33, when the engagement bar 21 is inserted into the bar engagement portion 32, the concave engagement portion 2 of the engagement bar 21 is just inserted.
A planar upper wall surface 34 is formed so as to be substantially flush with the 7-side engaging surface 27c (the lower surface of the four side surfaces of the engaging bar 21). Thereby, even if the rotation claw 45 is rotated by the spring 50 when the engagement bar 21 is not inserted, the rotation angle can be regulated by the upper wall surface 34. In FIG. 1, the bottom wall surface 35
Is formed substantially parallel to the upper wall surface 34, but the bottom wall surface 35
Is not limited to this, and can be variously modified as long as the rotation of the rotation claw 45 is not hindered.

On the lower side of the rotation space 33,
A rolling portion 36 is formed. The flat bottom surface of the rolling portion 36 is a rolling surface 37, and the regulation ball 40 rolls along the rolling surface 37. This rolling portion 36 is
When the sliding door 13 collides with the door stop 14, it is a space in which the regulation ball 40 rolls toward the fixed body 12 side in FIG.
That is, the rolling portion 36 receives the restriction ball 40 in the normal state in which the sliding door 13 is stopped, and the receiving portion 4
1 and the rolling surface 37 described above, and a collision portion 42 with which the restriction ball 40 collides during a collision. Of these, the rolling surface 37 can be easily moved to the collision portion 42 by the inertial force of the rolling surface 37 at the time of a collision, and in the natural state where the sliding door 13 is stopped, the rolling surface 37 is restricted to the receiving portion 41.
Is formed so as to return to and come into contact with each other. That is, the rolling surface 37 is an inclined surface where the receiving portion 41 side is lowered and the collision portion 42 side is raised.

Since the regulation sphere 40 functions as a regulation member, it is made of a material such as steel which is not easily deformed.

Here, the side walls forming the collision portion 42 are collision walls A and B formed by being inclined at a predetermined angle as shown in FIG. In this figure, the front case 3 of the casing 30 is attached to the end of the collision unit 42 on the fixed body 12 side.
A collision wall A is formed by obliquely notching 0a. The collision wall A is a wall surface that first collides when the sliding door 13 collides with the door stop 14 and the regulation ball 40 advances due to inertial force, and when the regulation ball 40 collides, the traveling direction of the regulation ball 40. To change to the collision wall B. The collision wall A is inclined by, for example, about 35 to 45 degrees with respect to the traveling direction of the regulation ball 40, and the other collision wall B approaches the fixed body 12 side.
Is formed so as to be close to.

In addition, the collision wall B moves the restriction ball 40 into the collision wall B.
Is reflected on the opposite wall C on the opposite side. Therefore, the collision wall B is formed so as to be inclined by, for example, approximately 5 to 25 degrees with respect to the initial traveling direction of the restricted sphere 40. Here, the inclination direction of the collision wall B is formed so as to extend from the rolling portion 36 to the outside of the side case 30b forming the casing 30. When the restriction sphere 40 is reflected by the collision wall B, the restriction sphere 40 advances toward the facing wall C. That is, the regulation ball 40 repeatedly reciprocates between the opposing wall A and the collision wall B a plurality of times.

The above-mentioned facing wall C and the collision wall B are set to have any inclination angles as long as the restricting sphere 40 is repeatedly reflected between the facing wall C and the collision wall B a plurality of times. It doesn't matter. Due to the configuration in which the reflection can be performed a plurality of times, the operation of immediately returning to the receiving portion 41 side after the regulation ball 40 collides with the front case 30a is prohibited.

The rotating space 33 has a rotating claw 45 as a rotating member. As shown in FIG. 1, the rotating claw 45 has a flat upper end surface 45 a, and the upper end surface 4 a
5a is formed so as to be in surface contact with the upper wall surface 34 of the rotating space 33. The rotating claw 45 is rotatably supported by the rotating shaft 46 so as to be in a position where such upper surface 45a can be brought into surface contact. Further, a claw portion 47 is formed on the upper end surface 45a at an end portion on the fixed body 12 side.
The claw portion 47 is a portion that fits into the above-described concave engagement portion 27, and is formed in a triangular protrusion shape having a triangular cross section corresponding to the substantially triangular groove-shaped concave engagement portion 27. In addition, this claw portion 47
The inclination angles of the wall surfaces 47a and 47b of the concave engaging portion 2 are the same.
The wall surfaces 27a and 27b of No. 7 are formed at the same angle.

A spring receiving portion 48 is provided on the rotating claw 45. The spring receiving portion 48 is provided so as to project downward from the lower end surface side of the claw portion 47. The spring receiving portion 48 has a coil-shaped spring 5 as an elastic member.
0 abuts. The spring 50 is the fixed body 1 of the rotation space 33.
One end side is locked to the side wall 51 opposite to the 2 side,
The other end side is in contact with the spring receiving portion 48. As a result, the spring receiving portion 48 is given a pressing force from the spring 50,
Normally, the upper wall surface 34 of the turning space 33 and the upper end surface 45a of the turning claw 45 are kept in contact with each other.

The side surface 45b of the rotating claw 45 closer to the fixed body 12 than the part where the claw portion 47 is formed is formed into a gentle curved surface. Thereby, the turning space 3
The side surface 45b is provided on the front case 30a on the fixed body 12 side of FIG.
Even if the abutting contacts, the rotating claw 45 can be smoothly rotated.

A pressing portion having a lower surface which is parallel to the rolling surface 37 is provided at a position (rolling portion 36 side) on the side opposite to the portion where the claw portion 47 is formed, of the rotating claw 45. 52 is formed. Even if the rotating claw 45 is about to rotate, the pressing portion 52 is
It has a function of restricting the rotation of the rotating claw 45 by coming into contact with the restriction ball 40. Thereby, the sliding door 13
Even when an attempt is made to rotate the rotating claw 45 to the rolling portion 36 side in an attempt to slide the engaging bar 21 in the fitted state immediately after the collision with the door stop 14 in the pulling direction,
By blocking the rotation of the rotation claw 45, the sliding (pulling out) of the engagement bar 21 is restricted.

Here, even when the engaging bar 21 slides, when the pressing portion 52 is pressing the regulating ball 40, the claw portions 47 are engaged with each other in the state of being fitted in the concave engaging portion 27. It needs to be fixed. That is, the protrusion height of the claw portion 47 and the recess depth of the concave engaging portion 27 are set to be larger than the rotation dimension until the rotation claw 45 rotates and contacts the regulation ball 40. There is.

The operation of the bounce prevention device 10 having the above structure will be described below. First, when the sliding door 13 is closed from the open state toward the door stop 14, the moving body 11 attached to the sliding door 13 advances with respect to the fixed body 12 attached to the door stop 14. Then, the moving body 11 and the fixed body 12 come into contact with each other, but in this case, the engagement bar 21 is inserted into the bar engaging portion 32 provided inside the moving body 11.

When the engagement bar 21 is inserted into the bar engagement portion 32, the pointed portion 21 a first contacts the claw portion 47. Further, by inserting the engagement bar 21, the pointed portion 21a pushes the claw portion 47 downward while resisting the elastic force of the spring 50. At this time, the regulation ball 40 is held by the receiving portion 41 by the inertial force associated with the movement of the sliding door 13.
Therefore, the engagement bar 21 can push the claw portion 47 downward, and thereby the rotation claw 45 rotates about the rotation shaft 46. When the engaging bar 21 further advances, the concave engaging portion 27 and the claw portion 47 of the engaging bar 21 are fitted to each other by the elastic force of the spring 50. When the concave engaging portion 27 and the claw portion 47 are fitted to each other,
The mounting position of the moving body 11 is adjusted so that the sliding door 13 and the door stop 14 collide with each other.

Here, when the concave fitting portion 27 and the claw portion 47 are fitted, the sliding door 13 collides with the door stopper 14. Then, the sliding door 13 hits the door 1 by the reaction of this collision.
Attempt to bounce back from 4.

On the other hand, when the sliding door 13 collides with the door stop 14, the sliding door 13 suddenly stops due to the collision between the sliding doors 13 and the restricting ball 40 by the inertial force of the rolling ball 36.
It rolls on the (rolling surface 37) and moves to the collision portion 42. In this case, the regulation ball 40 that has moved to the collision portion 42 first collides with the collision wall A. The restricting ball 40 bounced back by the collision wall A due to the collision reaction changes its traveling direction and collides with the collision wall B.
Head to. Then, the regulation ball 40 collides with the collision wall B,
The collision wall B bounces back and collides with the opposing wall C. After that, the collision between the collision wall B and the opposing wall C is repeated a plurality of times.

When the collision between the collision wall B and the opposing wall C is repeated a predetermined number of times, a fixed time elapses. Before this time elapses, the sliding door 13 tries to rebound due to a reaction due to the collision with the door stop 14.
As the sliding door 13 rebounds, the wall surface 4 of the claw portion 47
The wall surface 7a of the claw portion 47 is pushed down by the wall surface 27a of the engaging bar 21 as the wall surface 7a of the engaging portion 21 collides with the wall surface 27a of the concave engaging portion 27 and the rebound of the sliding door 13 progresses. As a result, the rotating claw 45 starts to rotate, and the pressing portion 52 of the rotating claw 45 starts to move toward the lower side (rolling surface 36 side).

Here, as described above, the restricting ball 40 does not return to the receiving portion 41 and is present in the collision portion 42 by repeating a plurality of collisions. Therefore, when the rotating claw 45 moves downward, the pressing portion 52 comes into contact with the regulation ball 40 and presses the regulation ball 40. When the pressing portion 52 is pressing the regulation ball 40, the rotation claw 45 cannot rotate any more due to the presence of the regulation ball 40. Therefore, even if the sliding door 13 attempts to move away from the door stop 14 due to the inertial force of the rebound, it cannot move any further. That is,
Subsequent rebounding of the sliding door 13 is stopped.

When the vibration and energy of the rebound of the sliding door 13 are calmed down, the claw portion 47 and the concave engagement portion 27 are provided.
A clearance is generated between the two, which causes the regulation ball 4
0 does not come into contact with the pressing portion 52 and becomes free. As a result, the restricted sphere 40 fits in the original place. Further, in the state where no clearance is generated between the claw portion 47 and the concave engagement portion 27 and the pressing portion 52 is pressing the regulation ball 40, the lower portion of the wall surface 27a is in contact with the upper portion of the wall surface 47a. At the same time, the wall surface 27b and the wall surface 27b are separated from each other so that there is a gap. Therefore, sliding door 1
Wall surface 2 can be easily moved by moving door 3 toward door 14 side slightly
The contact state between 7a and the wall surface 47a is released, and the rotating claw 45
Rotates slightly toward the upper side (bar engaging portion 32 side). That is, when the sliding door 13 is moved slightly toward the door stop 14 side, the pressing portion 52 is also moved slightly upward. As a result, the pressed state of the pressing portion 52 against the regulation ball 40 is released, the regulation ball 40 becomes free, rolls on the rolling surface 37, and is received by the receiving portion 41. As a result, the regulated ball 40 will fit in the original place.

Further, when the regulation ball 40 exists in the receiving portion 41, the rotation of the rotating claw 45 is not obstructed by the regulation ball 40. Therefore, when the sliding door 13 is pulled away from the door stop 14, the wall surface 27a of the concave engaging portion 27 can push down the wall surface 47a of the claw portion 47, and the rotating claw 45 resists the elastic force of the spring 50. However, it can be freely rotated. By the rotation of the rotation claw 45, the claw portion 47 can be released from the state of being fitted in the concave engagement portion 27. After that, the sliding door 13 can be freely moved.

According to the bounce prevention device 10 having such a configuration, when the engagement bar 21 is inserted into the bar engagement portion 32, the concave engagement portion 27 and the claw portion 47 are fitted together. After this fitting or at the same time as the fitting, the sliding door 13 collides with the door stop 14, but the regulation ball 40 moves to the collision portion 42 due to the sudden stop of the sliding door 13 due to the collision. Then, the regulation ball 40 that has moved is held by the collision portion 42 until immediately after the rebound of the sliding door 13. By doing so, even if the engaging bar 21 slides in the pulling-out direction as the sliding door 13 rebounds, and thereby the turning claw 45 tries to turn, the turning bar 40 cannot turn due to the existence of the restriction ball 40.

As a result, the sliding door 13 has a door stop of 14
It can be prevented from bouncing away from the door and a gap can be prevented from being formed between the sliding door 13 and the door stop 14. In this way, the rebound of the sliding door 13 can be prevented, so that it is possible to prevent the generation of a cold draft due to the opening of the sliding door 13 in the season such as winter. Especially, in the sliding door 13 such as sash in recent years,
Since the resistance between the roller and the rail is small, the rebound of the sliding door 13 easily occurs, but in the present invention, the rebound of the sliding door 13 can be effectively prevented.

Further, even if there is a reaction due to the collision between the sliding door 13 and the door stop 14, the sliding door 13 does not open, so that the sliding door 13 can be pulled to the door stop 14 without releasing the hand,
It is released from the work of reclosing the sliding door 13 again and again.
Thereby, the convenience when closing the sliding door 13 improves.

Further, the claw portion 47 is provided so as to project. As a result, the sliding door 13 bounces,
When the claw portion 47 is about to come off the concave engagement portion 27,
The rotating claw 45 surely rotates. At that time, sliding door 13
Since the restriction ball 40 moves to the collision portion 42 due to the sudden stop of the sliding door 13 due to the collision of the door stop 14, the rotation claw 45 cannot rotate and the engagement bar 21 is prevented from being pulled out. As a result, even if the sliding door 13 bounces and tries to separate from the door stop 14, it cannot be separated.

The engaging bar 21 is inserted into the bar engaging part 32 by providing the claw part 47 on the rotating claw 45 side and the concave engaging part 27 on the engaging bar 21 side. In this case, since the engaging bar 21 does not have the protruding claw portion 47, it is not necessary to provide the opening area of the opening portion 30g more than necessary. As described above, by not increasing the opening area of the opening 30g, it is possible to optimize the position where the engaging bar 21 hits the rotating claw 45.

The claw portion 47 may be provided on the engaging bar 21 and the concave engagement portion 27 may be provided on the rotating claw 45 side.
In this case, the opening area of the opening 30g may be increased corresponding to the insertion of the engagement bar 21 provided with the claw portion 47.

Further, the protrusion height of the claw portion 47 and the recess depth of the concave engagement portion 27 are determined by the rotation distance of the rotation claw 45 until the pressing portion 52 comes into contact with the regulation ball 40 and the rotation thereof is regulated. Is formed larger than. For this reason, the regulation ball 40 is collided with the collision portion 42.
In the state existing in 1), even if the engaging bar 21 tries to slide due to the rebound of the sliding door 13, the claw portion 47 and the concave engaging portion 27 cannot be removed while being engaged with each other. Thereby, the fitting state (connection state) between the rotating claw 45 and the engagement bar 21 can be maintained.

Further, the regulation ball 40 is provided on the rolling surface 37, and is constructed so that the regulation ball 40 exists in the receiving portion 41 by its own weight during normal times other than collision. For this reason, the turning claw 45 is normally operated by the turning claw 45 other than the collision.
The rotation is not restricted by. Further, even when the regulation ball 40 is pushed by the pressing portion 52 when the sliding door 13 rebounds, the rotation claw 45 is pushed by the spring 50 and slightly rotated so that the pushing force against the regulation ball 40 is exerted. When released, the regulation ball 40 rolls on the rolling surface 37 from the collision portion 42 by its own weight. As a result, when the sliding door 13 is opened except at the time of rebounding, the regulation ball 40 moves the regulation ball 40.
The sliding of No. 3 is not obstructed, and the sliding door 13 can be pushed open well.

Further, a pressing portion 52 is provided and this pressing portion 52
Since the regulation sphere 40 is pressed by means of, the clearance between the regulation sphere 40 and the rotating claw 45 is reduced,
It is possible to favorably regulate the rotation of the rotation claw 45 by the regulation ball 40. Further, since the regulation ball 40 is a spherical member, the regulation ball 40 can easily roll in the rolling portion 36.

Further, since the collision walls A and B are provided in the collision portion 42 where the regulation ball 40 advances when the sliding door 13 and the door stop 14 collide, the regulation ball 40 is divided into the collision wall B and the opposing wall C. The collision will be repeated. For this reason,
Compared with the case where the regulated ball 40 does not collide multiple times,
The extra time elapses as much as the collision between the collision wall B and the opposing wall C is repeated. As a result, even if the engagement bar 21 slides in the pull-out direction during the plurality of collisions, when the rotation claw 45 starts to rotate due to the slide, the pressing portion 52 ensures the restriction ball 40. Is pressed. Therefore, the sliding door 13 cannot be separated from the door stop 14.

That is, when the collision walls A and B are not provided, the restriction ball 40 bounces immediately, and the rotating claw 45 rotates and the pressing portion 52 returns to its original position before coming into contact with the restriction ball 52. May return to. However, such a collision wall A,
By providing B, it becomes possible to reliably press the regulation ball 40 with the pressing portion 52 when the sliding door 13 and the door stop 14 collide.

Further, the rotating claw 45 is biased by a spring 50. By this biasing force, when the engaging bar 21 is inserted into the bar engaging portion 32 and the rotating claw 45 is rotated, the claw portion 47 can be elastically biased toward the concave engaging portion 27. Further, the engaging bar 21 is attached to the moving body 11
Even when it is not inserted into the
By receiving the urging force from, the state of being in contact with the upper end surface 45a can be maintained.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIGS. 5 and 6. In the bounce prevention device 60 of the present embodiment, the same members and configurations as those described in the first embodiment will be described with the same reference numerals.

In these figures, a piston member 61 is provided on the back side of the bar engaging portion 32. The piston member 61 is pushed by the pointed portion 21a of the engaging bar 21 when the pointed portion 21a hits the collision portion 61a. The bar engaging portion 32 is provided with a piston holding portion 62. This piston holding part 6
A concave portion 63a having a cross-section corresponding to the cross-sectional shape of the piston member 61 and a deformed concave portion 63b formed so that one wall (lower wall) of the concave portion does not significantly project are formed in the second member 2. The piston member 61 is satisfactorily slidable by fitting the piston member 61 into the recess 63a and the deformed recess 63b.

Further, a protruding end of a spring member 64 as a biasing force applying means is located at a portion where the piston member 61 projects rearward from the recess 63 of the piston holding portion 62. The spring member 64 applies an urging force to the piston member 61 so as to return toward the door stop 14 side. The other end of the spring member 64 is connected to the spring mounting portion 6
It is attached to 5.

A notch 66 is formed in the piston member 61 in the middle thereof. A cam member 70 is provided so as to engage with the cutout portion 66. As shown in FIG. 5, the cam member 70 is provided so as to be rotatable about a rotation shaft 46 that serves as a rotation fulcrum of the rotation claw 45. A protrusion 71 extends from the rotating shaft 46 toward the piston member 61. The tip 71a of the protrusion 71 is always fitted into the above-mentioned cutout 66. Therefore, when the piston member 61 slides, the protrusion 71 moves along with the movement of the notch 66 and the rotation shaft 4 moves.
Rotate around 6. In this way, the cam member 7
0 is configured to rotate in association with sliding of the piston member 61.

The piston member 61 has a ball holding portion 72 extending toward the rolling portion 36. This sphere holder 72
In the state in which the engagement bar 21 is not inserted, the regulation ball 40 is held between the receiving portion 41 and the tip end portion 72a which is perpendicular to the paper surface and extends toward the back side in FIG. Is possible. However,
The piston member 61 is pushed in by the engagement bar 21,
When the cam member 70 rotates (counterclockwise in FIG. 5), the holding of the restriction ball 40 by the ball holding portion 72 is released, and the restriction ball 40 becomes movable on the rolling surface 37 thereafter. .

Here, the cam member 70 is formed of a flat plate-shaped member, but as shown in FIG. 6, the tip portion 72a of the cam member 70 is formed by bending the tip portion of the flat plate-shaped member. . Thereby, the regulation ball 40 can be favorably held by the tip portion 72a.
Further, when the cam member 70 is rotated toward the collision portion 42 side with the sliding of the piston member 61, the clearance between the tip portion 72 a and the rolling surface 37 is such that the restriction ball 40 can pass through. It is provided. As a result, when the pressing of the restricted sphere 40 by the pressing portion 52 is released, the restricted sphere 4
It is possible for 0 to immediately return to the receiving portion 41.

In the second embodiment, the case 30 has two side cases 30b and 30c, an inner case 30d sandwiched between the side cases 30b and 30c, and the fixed body 14 side, which are opposite bodies. And a rear case 30e disposed on the side.

In the bounce prevention device 60 having the above structure, the piston member 61 does not slide at all when the engagement bar 21 is not inserted.
The cam member 70 that interlocks with the sliding of the piston member 61 also does not rotate. In a state where the cam member 70 does not rotate, the cam member 70 maintains the state in which the regulating ball 40 is held via the piston member 61 by the urging force of the spring member 64.

As a result, even if the sliding door 13 pulled with a force to close it decelerates, and the restricting ball 40 tries to pop out due to inertial force, it can be prevented. That is, if the cam member 70 is not provided, it is not possible to suppress the protrusion of the regulation ball 40. Therefore, when the sliding door 13 slows down, the regulation ball 40 pops out and remains in the collision portion 42. In this state, when the engagement bar 21 is inserted into the bar engagement portion 32, the rotation claw 45 tries to rotate even though it cannot rotate due to the existence of the regulation ball 40. As a result, the restricting ball 40 is pressed by the pressing portion 52 with an excessive force, and the engaging bar 2
1 or the inside of the moving body 11 may be damaged.

However, according to the bounce prevention device 60 of the present embodiment, the piston member 61 does not slide in the state where the engagement bar 21 is not inserted, so that the cam member 70 pops out of the regulation ball 40. Therefore, it is possible to prevent the engagement bar 21 and the moving body 11 from being damaged as described above.

In the bounce prevention device 60, when the engagement bar 21 is inserted into the bar engagement portion 32,
It works as follows. First, by inserting the engagement bar 21, the piston member 61 is pushed. As a result, the cam member 70 in which the protruding portion 71 is engaged with the cutout portion 66 of the piston member 61 is rotated, and the holding state of the regulation ball 40 is released.

When the engaging bar 21 is further inserted into the bar engaging portion 32, the sliding door 13 collides with the door stopper 14 and the claw portion 47 and the concave engaging portion 27 are firmly engaged. Then, due to this collision, the movement of the sliding door 13 toward the door stop 14 side is stopped, and the restriction ball 40 whose holding by the cam member 70 is released advances toward the collision portion 42. Here, when the sliding door 13 collides with the door stop 14,
The sliding door 13 tries to separate from the door stop 14 by the reaction of this collision. As a result, the engagement bar 21 tries to come out of the bar engagement portion 32 this time.

However, as described in the above-mentioned first embodiment, the wall surface 47a of the claw portion 47 collides with the wall surface 27a of the concave engaging portion 27, and the sliding door 13 is in contact with the door.
The wall surface 47a is pushed down by the wall surface 27a as the wall surface 47a moves in a direction away from 4. As a result, the rotating claw 45 rotates, and the pressing portion 52 of the rotating claw 45 moves toward the lower side (rolling surface 36 side).

Then, in the same manner as described in the above-mentioned first embodiment, the pressing portion 52 comes into contact with the restriction ball 40 to press the restriction ball 40. As a result, the rotating claw 45 cannot be rotated any more, and it is possible to prevent the sliding door 13 from attempting to separate from the door stop 14 due to a collision reaction.

According to the bounce prevention device 60 having such a configuration, the cam member 70 holds the regulation ball 40 in a normal state other than the time of collision. That is, it is possible to prevent the extra control ball 40 from jumping out to the collision portion 42 side. As a result, the engagement ball 21 can be prevented from being inserted into the bar engagement portion 32 in a state where the restriction ball 40 pops out and is located at the collision portion 42, and the engagement bar 21 and the moving body 11 are damaged. Can be prevented. In this way, by preventing the bounce prevention device 60 from being damaged, it becomes possible to contribute to the extension of the life of the device.

When the cam member 70 collides, the holding of the regulating ball 40 by the cam member 70 is released, and the sliding door 13 and the door stop 14 collide with each other, so that the regulating ball 40 pops out. Thereby, even if the sliding door 13 and the door stop 14 collide with each other and the sliding door 13 bounces due to the reaction of the collision, the rotation of the rotating claw 45 can be well regulated.

The piston member 61 has a spring member 6
By 4, the urging force is applied when the engagement bar 21 is inserted into the moving body 11 and slides. By doing so, when the engagement bar 21 is inserted into the movable body 11, the spring force 64 applies a biasing force to the piston member 61 against the insertion of the engagement bar 21.
That is, the engaging bar 21 inserted in the moving body 11
The piston member 61 is pushed back by the spring member 64. Thereby, the cam member 70 interlocked with the sliding of the piston member 61 can return to the state before the engagement bar 21 is inserted.

The first and second embodiments of the present invention have been described above, but the present invention can be modified in various ways. For example, the collision walls A and B shown in the first embodiment are used in the second embodiment, but the collision walls A and B do not necessarily have to be provided. In other words, it is preferable to provide the collision walls A and B in the sense of reliably preventing the rebound. Further, the engagement bar 21 may have other shapes such as a combination of a cylinder and a cone, instead of the main body having a quadrangular prism shape and the tips of the quadrangular pyramids. When the main body of the engaging bar 21 is a column, the shape on the side of the opening 30g is also preferably circular.

Further, in the above-described second embodiment, the rotation of the rotating claw 45 and the cam member 70 are separately and independently rotated.
A gear or the like may be provided between 0 to interlock the rotation of the cam member 70 in the direction opposite to the rotation direction of the rotation claw 45. Even with such a configuration, the cam member 70 can be rotated to release the holding of the restriction ball 40, and the piston member 61 can be omitted.

Further, the engaging bar 21 may be composed of two members, and the projecting length of the engaging bar 21 may be adjusted by screwing between the two members. In this way, when the length is adjustable by screwing, it is not necessary to pay close attention to the mounting position when mounting and fixing the sliding door 13 or the door stop 14, and the engaging bar 21 is mainly the bar engaging portion. It suffices if attention is paid to the position where it is inserted into 32. That is, it is freed from the delicate size adjustment work at the time of mounting and fixing.

Further, the engaging bar 21 may be constructed so as to be foldable by using, for example, a hinge. With such a configuration, the engagement bar 21 may be folded when the rebound preventing devices 10 and 60 are not used, for example, when the sliding door 13 is kept open for a long time. This way, sliding door 1
The engaging bar 21 does not project into the open portion of the pulling member 3 and does not interfere.

The spring 50 and the rotating claw 45 may prevent the sliding door 13 from rebounding without providing the restricting ball 40 and the rolling surface 37. However, since the spring 50 alone is not sufficient to prevent rebound, it is necessary to add some measures such as making the wall surface 47a a steep slope and the wall surface 47b a gentle slope with respect to the inclination angles of the wall surfaces 47a and 47b of the claw portion 47.

In addition, in the above-mentioned respective embodiments, the case where the present invention is applied to the sliding door 13 has been described, but the application of the present invention is not limited to this, and may be used for a blind, for example. Further, it is possible to use it as a temporary connecting tool for preventing rebound of an activity body (pulley or the like) other than the sliding door 13 sliding on the rail. Further, the present invention is applicable not only to the case of sliding on a rail, but also to the case where two members do not bounce even if they collide with each other and it is necessary to temporarily contact (connect) them. .

[0092]

According to the present invention, when the engaging member is inserted into the moving body, the rotating member inside the moving body is rotated and the rotating member and the engaging member are fitted together. Then, after the fitting or when the sliding door collides with the door stop at the same time as the fitting, the restricting member moves to a position for restricting the rotation of the rotating member by its inertial force. As a result, the rotating member cannot rotate in the direction in which it disengages from the engaging member, and even if the sliding door tries to separate from the door stop due to the reaction of the impact due to the collision between the sliding door and the door stop, it cannot be separated.
Therefore, it is possible to prevent a gap from being generated between the sliding door and the door stopper. Even if a recoil occurs due to a collision between the sliding door and the door stop, the sliding door does not open.Therefore, in order to eliminate the gap due to the recoil, pull the sliding door to the door stop without releasing your hand or close the sliding door again and again. Freed from work. This improves convenience when closing the sliding door.
