Description

[0001]
BACKGROUND OF THE INVENTION
The present invention can hold a projecting position that is sandwiched between the door and the door stop frame and prevents the door from being fully closed, and moves to the immersive position so as not to prevent the door from being fully closed when it hits the door stop frame. It is related with the safety device for doors provided with the stopper member from which the state which can be selected is selected.
[0002]
[Prior art]
In everyday life, the doors can be closed with force. Inadvertently closing the door to give such acceleration may cause an accident in which a finger is caught between the door and the door stop frame. In order not to induce such an accident, even if the sliding door is inadvertently closed, a stopper that can move freely between the vertical fence of the sliding door and the door stopper frame so that a gap is opened between the vertical fence and the door stopper frame. Japanese Patent Application Laid-Open No. H8-4409 discloses a technique for providing the above.
[0003]
[Problems to be solved by the invention]
However, according to this prior art, when the sliding door is opened, the stopper automatically protrudes between the vertical fence and the door stop frame, so that the stopper always comes into contact when the door is closed. Therefore, according to this, in order to fully close the sliding door, the stopper must be returned to the release position each time. While this is certain in terms of safety, there is a concern that it may be annoying for those who are conscious of closing the sliding doors.
[0004]
The present invention has been devised to solve such problems of the prior art, and the main purpose of the present invention is troublesome when consciously closing without losing the security when closed carelessly. The purpose is to improve the safety device for the door so as not to let the user feel it.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, in the first aspect of the present invention, the door safety that prevents the doors (2, 3) from being fully closed when an acceleration (for example, 0.2 G) exceeding a predetermined value is applied . It is a device, and a predetermined length from the surface of the door facing the door-holding frame, and a slide member (12) provided on the door portion facing the door-holding frame so as to be slidable in the door opening / closing direction A stopper member (13) projectingly provided on the slide member and a first spring provided between the door and the stopper member and biasing the slide member in a direction in which the stopper member projects. A member (14), a weight member (15) provided on the slide member so as to be slidable in the opening and closing direction of the door, and provided between the slide member and the weight member; The second case biasing in the direction After the member (16) and the weight member are displaced to a predetermined position in the door opening direction against the slide member against the biasing force of the second spring member, the slide member is moved to the first position. When the spring member is displaced to a predetermined position in the door opening direction against the biasing force of the spring member, it engages with the weight member, and enters the door of the stopper member through the weight member. Limiting means (19) provided on the door side to brake the sliding of the slide member with respect to the door so as to prevent the immersion of the slide member, and the weight member in a predetermined direction in the door opening direction with respect to the slide member when displaced to the position, so as to the weights member and engageable to retain the relative position with respect to the slide member of the weights member, this having a locking means provided on the slide member side (18) It was assumed to be characterized.
[0006]
In this way , the door is closed vigorously , and when an acceleration of a predetermined value or more in the closing direction of the door acts on the door, the sliding of the slide member with respect to the door is braked and the stopper member is maintained in a protruding state. Is done. Thereby, it is prevented that a finger is packed between the door and the door stop frame. That is, the door safety device operates as a finger pad safety device. On the other hand, there is no resistance to slowly closing the door. In addition, when acceleration exceeding a predetermined value is applied to the door even once in the process of closing the door, the weight member is displaced to a predetermined position in the door opening direction with respect to the slide member, and is held at that position by the locking means. The sliding of the sliding member with respect to the door is braked. Therefore, after that, even if the door is slowly closed, the finger padding safety device is operated so that acceleration exceeding a predetermined value is not applied to the door.
[0007]
According to a second aspect of the present invention, in addition to the above configuration, when the slide member is displaced in the door closing direction by the biasing force of the first spring member from a state in which the slide member is displaced in the door opening direction with respect to the door. Further, the door is provided with a release means (26) that engages with the lock means and displaces the lock means in a direction to release the engagement between the lock means and the weight member. It was supposed to be .
[0008]
According to a third aspect of the present invention, in addition to the above configuration, the weight member has a slope (20) on the restricting means side, and the restricting means is a guide groove (22 formed in a duck supporting the door). ) Is slidable on the portion of the door facing the door and protrudes from the surface facing the guide groove of the door, and has an inclined surface (21) that engages the inclined surface of the weight member on the weight member side. Then, after the weight member is displaced to a predetermined position in the door opening direction against the slide member against the biasing force of the second spring member, the slide member is attached to the first spring member. When it is displaced to a predetermined position in the door opening direction against the force, it is pressed by the inclined surface of the restricting means and displaced toward the guide groove, and is pressed against the guide groove. It was characterized by that. As a result, the braking force is applied to the door at the same time that the finger padding safety device operates.
[0009]
According to a fourth aspect of the present invention, a low friction member (guide plate 17) is interposed between the weight member and the restricting means . Thereby, cooperation with the operation | movement of a finger pad safety device and the operation | movement of a door braking device becomes smooth.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0011]
FIG. 7 shows an example of a residential aluminum sash to which the present invention is applied. This sash has two sliding-type glass shojis 2 and 3 slidably incorporated inside the fixed frame 1 and is opposed to the door-to-door frame 1a in the upper gutter 4 formed hollow with an aluminum alloy material. The safety device 5 of the present invention is incorporated in the part. The safety device 5 according to the present invention is not limited to the illustrated glass shoji but can be applied to all types of sliding doors such as a panel-type sliding door and a basket.
[0012]
As shown in FIGS. 1 to 6, the safety device 5 is incorporated in the casing 11 so as to be movable along the opening / closing direction of the shoji 3 and the casing 11 that is substantially integrated with the upper collar 4. A slide member 12, a stopper projection 13 formed integrally with the slide member 12 so that the tip of the slide member 12 can protrude and retract from the surface facing the door stop frame 1a, and a first compression coil for holding the protruding state of the stopper projection 13 The spring 14, the weight member 15 assembled so as to be movable in the same direction as the slide member 12 with respect to the slide member 12, and the weight member 15 for holding the weight member 15 at the end face side position (advance position) of the shoji 3 A second compression coil spring 16 and a guide plate 17 and a lock plate which are pivotally mounted on the upper end of the slide member 12 so that each free end can be pivoted up and down. And over bets 18 consists of a brake member 19 for a vertically movable upper wall of the casing 11.
[0013]
Hereinafter, it will be described in more detail with the operating procedure. The movement of the shoji 3 in the closing direction is defined as forward and the movement in the opening direction is defined as backward.
[0014]
Normally, the slide member 12 is held at a position where the stopper projection 13 protrudes from the surface facing the door stop frame 1 a by the elastic force of the first compression coil spring 14. At the same time, the weight member 15 is also held at the advanced position by the elastic force of the second compression coil spring 16. Further, the guide plate 17 and the lock plate 19 are inclined so that the free ends thereof are directed downward, and the brake member 19 is lowered by its own weight (see FIG. 1).
[0015]
In this state, when the shoji 3 is slowly closed, the weight member 15 moves together without moving relative to the casing 11 fixed to the upper collar 4. Even if the stopper projection 13 hits the door stop frame 1a, there is nothing that prevents the slide member 12 from retreating. Therefore, the stopper projection 13 is immersed in the casing 11 without resistance, and the shoji 3 is completely closed (see FIG. 6). . Note that the extension force of the first compression coil spring 14 is always acting, and this is a force that prevents the slide member 12 from retreating. However, if this spring constant is determined to such an extent that the weight of the shoji cannot be pushed away. It doesn't matter at all. At this time, when the stopper projection 13 hits the door stop frame 1a, the slide member 12 moves backward against the extension force of the first compression coil spring 14, and the slide member 12 moves backward together . The upper surface of the weight member 15 is a rear-lowering slope 20, and the lower surface of the brake member 19 is a front-upward slope 21. Therefore, the inclined surface 20 of the weight member 15 retreating together with the slide member 12 presses the inclined surface 21 of the brake member 19 via the guide plate 17, and the brake member 19 is pushed upward with respect to the upper wall of the casing 11. The When the weight member 15 is in the forward position with respect to the slide member 12, the slope 20... Is kept so that the upper end of the brake member 19 pushed up by the weight member 15 does not come into pressure contact with the bottom of the groove 22 provided in the duck. 21 angles are defined.
[0016]
When the shoji 3 is closed vigorously, the weight member 15 cannot follow the acceleration of the shoji 3 due to the inertial action, so that the weight member 15 apparently retreats while the second compression coil spring 16 is being compressed (see FIG. 2). The acceleration at which the weight member 15 operates can be set as desired by the weight of the weight member 15 and the spring constant of the second compression coil spring 16, and may be set to operate at 0.2 G or more, for example. As shown in FIG. 2, even when the shoji 3 is closed vigorously, the slide member 12 causes the stopper projection 13 to face the door stop frame 1a by the elastic force of the first compression coil spring 14. It is held at a position protruding from the surface.
[0017]
The retreat limit of the weight member 15 is determined by the protrusion 23 provided on the slide member 12 and the hook-shaped portion 24 at the free end of the guide plate 17. Further, once the weight member 15 is retracted to the limit position, the free end of the lock plate 18 descends and is caught at the upper front corner of the weight member 15, and even if the acceleration decreases, the return movement of the weight member 15 to the advance position is prevented. Is done. In this state, since the lock plate 18 stretches between the slide member 12 and the weight member 15, when the stopper projection 13 strikes the door stop frame 1a, the slide member 12 moves backward while maintaining the retracted position of the weight member 15. (See FIG. 3).
[0018]
As described above, the upper surface of the weight member 15 is a rear-lowering slope 20, the lower surface of the brake member 19 is a front-upward slope 21, and the guide is sandwiched between the weight member 15 and the brake member 19. The plate 17 is formed of a synthetic resin material having a low friction coefficient, and the backward movement of the weight member 15 integrated with the slide member 12 is smoothly converted into the upward movement of the brake member 19. The guide plate 17 is pushed up by the retreat of the weight member 15, and at the same time, the brake member 19 is gradually pushed up and pressed against the groove 22 on the momoi side. The wedge effect causes a braking force to act on the shoji 3, and the slide member 12 cannot be retracted any more, leaving a finger tightness prevention dimension A between the door stop frame 1a and the end face 4a of the upper arm 4 of the shoji ( (See FIG. 4).
[0019]
On the other hand, a claw 25 that is hooked on the upper surface of the slide member 12 is provided on the side of the pivot end 18a of the lock plate 18, and a resilient claw 26 that can be bent and deformed upward is formed on the upper wall of the casing 11. The claw 25 of the lock plate 18 pushes back the elastic claw 26 during the stroke in which the stopper protrusion 13 hits the door stop frame 1a and the slide member 12 is somewhat retracted. (See FIG. 4).
[0020]
When the stationary shoji 3 is opened slightly while leaving the finger tightness prevention dimension A, the slide member 12 is pushed forward by the first compression coil spring 14 and the lock plate 18 is dragged by this, but the pivot plate 18 is pivoted. Since the claw 25 of the support end 18a is caught by the elastic claw 26, the long groove 27 along the moving direction of the shoji that receives the pivot end 18a of the lock plate 18 moves forward leaving the pivot end 18a. Then, the restriction on the claw 25 of the lock plate 18 is released , the claw 25 is pressed by the bullet claw 26, and the lock plate 18 pivots so that its free end faces upward, thereby preventing the movement of the weight member 15. Power is released. Thus, the weight member 15 is returned to the initial position by the elastic force of the second compression coil spring 16 (see FIG. 5).
[0021]
As described above, the slide member 12 can be retracted, and there is no trouble in closing the shoji 3.
[0022]
If the shoji 3 is closed at such a speed that the weight member 15 does not retract in the casing 11, there is nothing to prevent the stopper protrusion 13 from entering, and therefore the shoji 3 can be fully closed without resistance.
[0023]
In any case, if the acceleration at which the weight member 15 is held in the retracted position is given to the shoji 3 even once, the stopper projection 13 will work even if it is closed slowly at the end. Even if the stopper projection 13 works, the lock plate 18 is automatically released by moving the shoji 3 slightly in the opening direction, so that the shoji 3 can be fully closed.
[0024]
【The invention's effect】
As described above, according to the present invention, the stopper function for preventing the fingers from being pinched when inadvertently closing is automatically operated according to the degree of acceleration acting on the sliding door. It is possible to eliminate the inconvenience of forcing the user to cancel the stopper every time the user does not need to close it. Even when the stopper function is enabled, the stopper function is automatically released by a simple operation of opening the sliding door slightly, so that the user does not feel bothersome and slowly from the beginning. As long as it is closed, it will be fully closed without a sense of resistance, so you can make it a habit not to make a messy way to trigger an accident. In addition to this, it can be built in not only to sash type sliding doors, but also to panel doors and coffins, so it is highly versatile and it is built into the top edge of the door, so it does not disturb people. You do n’t have to.
