Description

  The present invention relates to a device for preventing finger pinching of a door, such as a sliding door or a hinged door provided at a doorway or a window of a building.

  When closing a sliding door or a hinged door provided at a doorway or window of a building, an accident has occurred in which a finger is caught between the door and the door stop frame.

  In particular, in recent years, doors such as sashes have become heavier in order to improve heat insulation and sound insulation, and if a finger is caught between the door and the door stop frame, a serious injury will occur.

  However, with the already proposed finger pinching prevention device, once the finger pinching prevention device is activated, a release operation is required, or the device is established by integrating the door and the door frame, and can be retrofitted to an existing door. There were problems such as being unable to do so.

  In view of the above problems, an object of the present invention is to provide a door finger pinching prevention device that does not require a release operation after the operation of the finger pinching prevention device and can be retrofitted to an existing product.

  The above-described problem is a finger pinching prevention device that is attached to a door-holding frame or door and restricts the full closing of the door. The finger pinching prevention device of the door is restricted by the first restriction means and the second restriction means. When the door is closed at a predetermined force or less, the support is released by the first restriction means while being restricted by the second restriction means, and the support is fully closed. When the door is moved from the position where it is blocked to the position where it is retracted and the door is closed beyond a predetermined force, the restriction by the second restriction means is released, and the support remains in the position where the door is prevented from being fully closed. This is solved by a device for preventing finger pinching of the door.

  This finger pinching prevention device has a first restricting means and a second restricting means, and the support body causes the door to be fully closed by the force of closing the door by the cooperation of the first restricting means and the second restricting means. It is possible to control whether to move from the blocking position to the retracted position or remain in a position to prevent the door from being fully closed. When the door is closed with a predetermined force or less, the support is regulated by the second regulating means. In this state, the restriction by the first restricting means is released, the support moves from the position where the door is prevented from being fully closed to the position where it is retracted, allows the door to be fully closed, and closes the door beyond a predetermined force. In such a case, the restriction by the second restricting means is released, and the support body can be prevented from being fully closed by staying at a position that prevents the door from being fully closed.

  For this reason, when the door is closed beyond a predetermined force, the support prevents the door from being fully closed, so that fingers are prevented from being caught between the door and the door stop frame, and the door is again opened from the open state. When the full closing operation is performed, whether the support moves again from the position that prevents the door from being fully closed to the retreat position or remains in the position that prevents the door from being fully closed. Because it is selected, the door can be closed and closed only by opening and closing the door. Once the door is fully closed, the door can be closed without releasing the pinch prevention device. Opening and closing operations can be performed.

  Further, this finger pinching prevention device is a position in which the support is retracted from a position at which the support is prevented from being fully closed by the force of closing the door in cooperation with the first restricting means and the second restricting means. Therefore, it is not necessary to incorporate a finger pinching prevention device into a door or door-holding frame, for example. It can also be attached to.

  In the above finger pinching prevention device, the support body is movable in an opening / closing direction of the door and rotatable about an axis perpendicular to the opening / closing direction of the door, and the first restricting means is perpendicular to the opening / closing direction of the door. It is preferable that the rotation of the supporting member is restricted, and the second restricting means restricts the movement of the support in the opening / closing direction of the door.

  Since the support body capable of moving in the door opening / closing direction and rotating around the axis perpendicular to the door opening / closing direction is regulated by the first regulating means and the second regulating means, respectively, The movement of the support and the rotation about the axis perpendicular to the opening / closing direction can realize the operation of the support according to the force when closing the door by the two restricting means.

  Furthermore, in the above-described finger pinching prevention device, the first restricting means includes an urging means that urges the support body to the restriction position, and the second restriction means urges the support body to the restriction position. It is good to have a force means.

  Since each of the first restricting means and the second restricting means has an urging means for urging the support body to the restriction position, the support body can be restricted to the restriction position by using the urging means. In addition, even when the support is moved or rotated from the restricted position, the original restricted position is restored by the urging means, so there is no need to perform a special release operation on the finger pinching prevention device. It can be restored to the state.

  Since the present invention is as described above, it is possible to provide a door finger pinching prevention device that does not require a release operation after the operation of the finger pinching prevention device and can be retrofitted to an existing product.

FIG.

  Next, embodiments of the present invention will be described with reference to the drawings.

  In the door finger pinching prevention device 1 attached to the sliding door type door stop frame according to the first embodiment of the present invention shown in FIGS. 1, 2 and 3, reference numeral 2 denotes a support, and reference numeral 6 denotes a support 2. A shaft body serving as a rotation shaft, 7 is a first urging means constituting the first restricting means, 9, 9 are second urging means constituting the second restricting means, and 12 is attached to the door finger pinching prevention device 1 Reference numeral 13 denotes a sliding door, 13 is a sliding door, and 14 is a door-side contact portion that is attached to the sliding door 13 and contacts the support 2.

  The support body 2 has a contact portion 3 that contacts the hinged door at one end portion of the rod-shaped shaft portion 4, and is fixed to the shaft body 6 that serves as a rotation shaft of the support body 2 at the other end portion. In addition, in cooperation with a support fixing portion 10 described later, the support 2 is configured by a braking portion 5 that stops the support 2 from rotating together with the shaft 6 around the shaft 6.

  Both ends 6b, 6b of the shaft body 6 are inserted into the gaps 11c, 11c extending in the opening / closing direction of the hinged doors provided on both side surfaces 11b, 11b of the box-shaped box 11 having a U-shaped cross section. It is attached in the box 11 so that it can move in the opening / closing direction of the hinged door along 11c.

  A torsion coil spring 7 as a first restricting means has one end portion fixed to the shaft body 6 and the other end portion fixed to the side surface portion 11b of the box 11 to rotate the shaft body 6 of the torsion coil spring 7. The rotation of the shaft body 6 is restricted by the urging force in the rotation direction as the shaft, and the support body is restricted to a position where the support body 2 integrated with the shaft body 6 is horizontal. Reference numeral 8 denotes a fixing portion for fixing one end portion of the torsion coil spring.

  Further, compression coil springs 9 and 9 as second urging means sandwich the support body between the bottom portion 11a of the box-shaped box 11 attached to the door stop frame 12 and the shaft body 6. It is interposed on both sides of the shaft body 6 and restricts the movement of the shaft body 6 toward the bottom 11 a of the box 11. Although not shown, the shaft body 6 is allowed to rotate between the shaft body 6 and the compression coil springs 9 and 9 and the compression coil springs 9 and 9 are biased to the shaft body 6. A spacer is interposed. When the support body fixing portion 10 is attached to the bottom portion 11a of the box 11 and the support body 2 is released from the restriction of the compression coil springs 9 and 9 as the second restricting means and moves to the bottom portion 11a side of the box 11. The rotation of the support body 2 around the shaft body 6 is restricted by the cooperation of the support body fixing part 10 and the braking part 5 of the support body 2. Here, the cooperation between the support fixing part 10 and the braking part 5 may be performed by a frictional force between the support fixing part 10 and the braking part 5, or provided in the support fixing part 10 and the braking part 5. It may be performed by fitting the concave and convex portions.

  As shown in FIG. 4A, in the normal state in which the sliding door is open, the support 2 is restricted from rotating around the shaft body 6 by the first restricting means including the torsion coil spring 7, and the support 2 is It is regulated to be in a horizontal state. Further, the support 2 is restricted from moving in the opening / closing direction of the sliding door by the second restricting means including the compression coil spring 9, and the braking portion 5 and the support fixing portion 10 attached to the box 11 do not cooperate. It is regulated to be positioned in a spaced state. In addition, when the support body 2 contacts the door side contact part 14 attached to the sliding door so that it may mention later, in order to accelerate | stimulate rotation of the support body 2, the rotation direction of the support body 2 from a horizontal state It may be regulated to be positioned in a slightly rotated state.

  When closing the sliding door, the door-side contact portion 14 attached to the sliding door contacts the contact portion 3 of the support body 2, and the force when closing the sliding door moves toward the support body 2 via the door-side contact portion 14. It is told.

  The force for releasing the restriction of the rotation of the support 2 around the shaft body 6 by the first restricting means comprising the torsion coil spring 7 and the opening / closing direction of the sliding door of the support 2 by the second restricting means comprising the compression coil spring 9. The force for releasing the restriction of movement is performed by adjusting the torsion coil spring 7 and the compression coil spring 9, respectively. The force necessary for releasing the restriction of the rotation of the support 2 around the shaft body 6 by the first restricting means comprising the torsion coil spring 7 is a predetermined force without danger of pinching a finger between the sliding door and the door stop frame. Set smaller. On the other hand, the force necessary to cancel the restriction of the movement of the support body 2 in the opening / closing direction of the support 2 by the second restriction means comprising the compression coil spring 9 is a predetermined force that does not cause a risk of pinching a finger between the sliding door and the door stop frame. Set larger than force.

  As shown in FIGS. 4B and 5, when the sliding door is closed with a predetermined force or less without risk of pinching the finger between the sliding door and the door-holding frame, the second compression coil spring 9 is formed by the force for closing the sliding door. The restriction of the movement of the support body 2 in the opening / closing direction of the support body 2 by the restriction means is not released, and the brake section 5 and the support body fixing section 10 attached to the box body 11 are located in a spaced apart state. Thus, the restriction of the rotation of the support body 2 around the shaft body 6 by the first restriction means comprising the torsion coil spring 7 is released, and the support body 2 releases the restriction of the rotation of the support body 2 around the shaft body 6. Since the restriction that the support body 2 is positioned in the horizontal state is released, the support body 2 rotates around the shaft body 6 from the horizontal state that prevents the sliding door from being fully closed, and allows the sliding door to be fully closed.

  On the other hand, as shown in FIGS. 4C and 6, when the sliding door is closed beyond a predetermined force that may cause a finger to be caught between the sliding door and the door-holding frame, the compression coil spring 9 From the state where the restriction of the movement of the support body 2 in the opening / closing direction of the support body 2 by the second restriction means is released, and the brake part 5 and the support body fixing part 10 attached to the box 11 are spaced apart from each other, The support body moves horizontally in the opening / closing direction of the sliding door so as to be positioned in a state where the distance between the cooperation of the brake part 5 and the support body fixing part 10 attached to the box 11 is reduced, and the torsion coil spring 7 is formed. The restriction of the rotation of the support body 2 around the shaft body 6 by the first restricting means is not released and the rotation of the support body 2 around the shaft body 6 is restricted, so that the support body 2 is in the original horizontal state or slightly Regulated by the position of the rotating state, the sliding door is fully closed Since stays in a position to stop abuts the abutting portion 3 of the support 2 is a door-side contact part 14 of the sliding door, it can be prevented fully closed sliding door.

  As described above, in the sliding door type sliding door, whether or not the sliding door can be fully closed can be adjusted by regulating the movement of the support body by the combination of the first regulating means and the second regulating means by the force when closing the sliding door. Therefore, the sliding door can be fully closed when there is a small force without the danger of pinching the finger, and the sliding door can be prevented from being fully closed when there is a large force with the danger of pinching the finger. Further, in each of the first restricting means and the second restricting means, the support body is regulated by the biasing force of the spring, so that the support body 2 is in the respective biasing means by opening the sliding door again. Thus, since the original position is restored, even if the finger pinching is once prevented, the original state can be restored without performing the restoration work.

  In the door pinching prevention device 21 attached to the sliding door type door stop frame according to the second embodiment of the present invention shown in FIG. 7, reference numeral 22 denotes a support, and 26 denotes a rotating shaft on which the support 22 rotates. The shaft body 27 is a first urging means constituting the first restricting means, and 29 and 29 are second urging means constituting the second restricting means.

  The support 22 has a contact portion 23 that contacts the hinged door at one end of a rod-shaped shaft portion 24, and a shaft 26 that rotates as a rotation shaft of the support 22 is rotated at the other end. The brake unit 25 is configured to rotate as a shaft and stop the rotation of the support body 22 around the shaft body 26 in cooperation with the support body fixing section 210. A torsion coil spring 27 as a first restricting means provided in the braking portion 25 of the support 22 has one end fixed to the shaft body 26 and the other end fixed to the braking portion 25, and a torsion coil. The support is regulated in a horizontal state by the bias of the spring 27.

  The shaft body 26 is circular in cross section at the central portion 26a, and both end portions 26b and 26b are square in cross section, and both end portions 26b and 26b are both side portions 211b and 211b of a U-shaped box 211 having a U-shaped cross section. Is inserted in gaps 211c and 211c extending in the opening / closing direction of the hinged door provided in the box 11, and is mounted in the box 11 so as to be movable in the opening / closing direction of the hinged door along the gaps 211c and 211c.

  Compression coil springs 29 and 29 as second urging means are respectively provided in the gaps 211c and 211c extending in the opening and closing direction of the hinged doors provided on both side surfaces 211b and 211b of the U-shaped box 211 having a U-shaped cross section. The body 22 is attached to a position where the door extends when the door is fully closed.

  The functions of the first urging means and the second urging means and the door opening / closing method are the same as in the first embodiment.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.

  In the said embodiment, although the case where the door finger pinching prevention apparatus was attached to the door stop frame of the door of a sliding door type was shown, you may attach a door finger pinching prevention apparatus to a sliding door. In addition, the door type is not limited to the sliding door type, and can be applied to the hinged door type. In this case, the door opening / closing direction is the free end opposite to the rotating shaft side of the hinged door. The direction is the tangential direction of the arc trajectory.

  The restricting means is not limited to an urging means such as a spring, and may be realized by a combination of a sensor that measures the opening / closing force of the door and a motor that is driven based on the measurement value measured by the sensor. However, it goes without saying that it may be achieved by a method such as magnetic force.
