Description

[Detailed explanation of the idea] The present invention relates to a folding door.

In this type of folding door, which is formed by folding and rotatably connecting door panels 3, 3 by a hinge 1, opening and closing operations are performed by a handle 4 provided on the hinge 1, as shown in FIG. Here, the handle 4 has conventionally been formed in a U-shape with horizontal rods 50, 50 provided at the upper and lower ends of a vertical rod 49, as shown in FIG. Due to human habit, the handle 4 is operated by grasping the vertical rod 49 in the hand as shown in FIG. However, if you operate the folding door by grasping the handle 4 in your hand in this way, as shown in Fig. The user's hand would get caught between the door panels 3, and especially when the folding door was folded forcefully, there was a risk that the user's hand would get caught between the door panels 3 and cause injury.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a folding door whose handle can be operated without fear of getting one's hand jammed between the door panels.

Therefore, in the present invention, a pair of door panels 3, 3 are folded and rotatably connected by a hinge 1, a handle 4 is provided protruding from the side of the hinge 1 on which the door panel 3 is folded, and a handle 4 is provided upwardly from the upper end of the door panel 3. In a folding door in which a latch 6 for extension and holding, which is spring-biased to protrude, is movable up and down, a vertically elongated protruding plate piece 4a that protrudes the handle 4 from the hinge 1 and a tip of the protruding plate piece 4a are used. The notch portion 52 is formed by an enlarged piece 4b that is integrally provided with the protruding plate piece 4a and has a diameter larger than the thickness of the protruding plate piece 4a, and the upper and lower center portions of the protruding plate piece 4a and the enlarged piece 4b are cut out with a vertical width larger than the size of a fist. The above object has been achieved by a folding door in which a knob 17 for lowering the latch 6 is attached to the hinge 1 at a position directly above the handle 4 so as to be movable up and down. Explain in detail.

The hinge 1 that connects the pair of door panels 3, 3 is composed of a receiver 1a and a connector 1b. Its cross-sectional shape is approximately U-shaped, and bearing protrusions 2, 2 are protruded from both ends thereof. The connector 1b is also formed in a vertically elongated manner with approximately the same length as the vertical dimension of the door panel 3, and has a fitting curved piece 5 having a substantially C-shaped cross section, and a harpoon-like protruding piece 8 of the door panel 3. The connector 1b is attached to one side end of the door panel 3 by being driven into the end face. By rotatably fitting the fitting curved piece 5 of the connector 1b onto the outer periphery of the bearing protrusions 2, 2 of the receiver 1a, the hinge 1 composed of the receiver 1a and the connector 1b As shown in FIG. 4, a pair of door panels 3, 3 are foldably connected. 4, the spacer is fitted into the receiver 1a in order to prevent the fitting curved pieces 5, 5 from disengaging from the bearing protrusions 2, 2, but the upper part of the receiver 1a is A spacer 9 as shown in FIG. 10c is used at the lower part of the receiver 1a, and a spacer 10 for mounting an operating tool as shown in FIG. 10a is used at the upper and lower center of the receiver 1a.

The knob 29 is attached with screws 30. The upper end of a lower operating rod 31 is fixed to this bush 28, and a drop 7 is attached to the lower end of the lower operating rod 31.
is attached with screw 32. Drop 7 is receiver 1a
and the spacer 9, and moves downward under its own weight so that the lower end protrudes downward from between the receiver 1a and the spacer 9. 7 by pulling up the lower operating rod 31 via the bush 28.
The receiver 1a is inserted between the receiver 1a and the spacer 9. Here, the bush 28 has a U-shaped spring 3.
6 is attached with a screw 37, and when the bush 28 is moved upward, the U-shaped spring 36 is elastically engaged with the screw 12 as shown in FIG. It is designed so that it can be maintained in a state where it is immersed between the two. Reference numeral 33 in FIG. 11 is a long hole provided in the lower operating rod 31. Further, 34 and 35 are caps attached to the upper and lower ends of the handle fixture 11. Further, the handles 4, 4 are attached with screws 39, 3 between the upper and lower knobs 17, 29 on the outer surface of the operating tool mounting spacer 10 and the outer surface of the handle mount 11, respectively.
It is installed at 9. Here, the side opposite to the side where the door panels 3, 3 fold and rotate, that is, the handle 4 attached to the handle mount 11 may be the same as the conventional one in FIG. 2, but the side where the door panels 3, 3 fold and rotate. That is, as the handle 4 attached to the spacer 10 for attaching the operating tool, the one shown in FIG. 5 is used. In other words, this device has a pair of upper and lower handles 4, 4 integrally protruding from a base plate 51.
is a protruding plate piece 4 that protrudes integrally from the surface of the substrate 51
a and an enlarged piece 4b which is integrally provided at the tip of the protruding plate piece 4a and has a diameter larger than the thickness dimension of the protruding plate piece 4a. Further, the vertical length of each handle 4 is formed to be long enough to be held between the thumb and index finger of the hand, for example, about 3 to 6 cm, and the vertical width of the notch 52 between the upper and lower handles 4, 4. The size is set so that a fist can fit inside. Of course, handles 4 as shown in FIG. 5 may be provided on both sides of the hinge 1.

The folding door is opened and closed by extending or folding the folding door by running the door along the road.

When the folding door is extended, the upper inclined surface 44 of the latch 6 protruding upward hits the upper rail 42, resists the spring 23, and moves the latch 6 downward. The latch 6 moves upward and the upper part of the latch 6 is fitted into the upper rail 42 as shown in FIG. This prevents the folding door from returning to its original folded state due to the reaction caused by the folding door. When the folding door is to be locked in this extended and closed state, the knob 29 is pushed down to lower the drop 7 and the lower part of the drop 7 is fitted into the lower rail 43.

To fold the folding door from the extended state, first push up the knob 29 and move the drop 7 upward to unlock it, and then push down the knob 17 to release the latch 6 into the spring 23. This is done by resisting and pulling down to disengage the latch 6 from within the upper rail 42. In this case, the handle 4 does not have a place for inserting fingers, so it is not possible to grasp the handle 4 by hand, and the handle 4 is operated by pinching the large piece 4b of the handle 4 with your fingers as shown in Fig. 6. The knob 29 can be pressed down by placing the index finger on the lower end surface of the upper handle 4 and pressing the upper surface of the knob 29 with the thumb in this state.

As mentioned above, in the present invention, the handle is formed by a protruding plate piece that protrudes from the hinge and an enlarged piece that is integrally provided at the tip of the protruding plate piece and has a diameter larger than the thickness of the protruding plate piece, so that the handle can be easily inserted into the handle. Because it is formed in a shape that makes it impossible to hold the handle, and the large piece is shaped so that it can be easily pinched with the fingers, the handle is operated by pinching the large piece with the fingers. There is no risk of getting your hands stuck between the door panels. In addition, a notch is formed by cutting out the upper and lower centers of the protruding plate piece and the enlarged piece with a vertical width larger than the size of a fist, and the knob for lowering the latch on the hinge can be moved up and down directly above the handle. Now that it is attached, put your fist in the notch and press down on the knob with your thumb to disengage the latch, then immediately pinch the large piece of the handle to open and close the door. The door can be opened and closed with good operability by performing the operation of the knob and the operation of the handle in a series of steps.
