Abstract

PURPOSE:To improve the operation performance even if a handle is set in any direction by forming a cylindrical projection part in a recessed part at a part of the installation fitting of the handle and installing the handle in turnable manner by inserting the handle basic part from the cut part of a rotary body. CONSTITUTION:A handle 16 is installed on a longitudinal rail 7 of a joint part between one door body 1 and the other door body 2. A cylindrical bulged part 20 having a recessed part 21 at a part is formed on one center surface of an installation fitting 17, and fixed on the longitudinal rail 7. A rotary body 28 is formed from a cylindrical part 32, etc., fitted with the circular hole 19 of the installation fitting 17, and the basic part of the handle 16 is inserted from a cut part 34, and installed in tunable manner. In the state where the handle 16 is set in the longitudinal direction, the basic part 16a contacts the bulging part 20 of the installation fitting 17, and the handle 6 is erected, and a sufficient gap L2 for inserting fingers between the longitudinal rail 7 is formed. When the handle 16 is set transversely, the basic part 16a contacts the recessed part 21 of the installation fitting 17 by the force of a coil spring 36, and the handle 16 approaches the door body side, and the projection width L1 reduces. Accordingly, the operation performance of the handle is improved, and the gap between the door bodies in the case when the folded door is opened can be reduced.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a handle in a folding door that opens by pivoting one end to one vertical stile, moving the other end along the upper and lower frames, and bending the middle part. .

(Prior Art) Japanese Patent Publication No. 61-4955 discloses a structure in which a handle is attached to the vertical stile at the center of a folding door, thereby reducing the range of movement of the hand when opening and closing the door.

(Problem to be Solved by the Invention) In the above-mentioned conventional technology, in order to improve operability, it is necessary to provide a space between the grip of one handle and the vertical stile so that a finger can be inserted comfortably. On the other hand, if this distance is provided, when opening the folding door, that is, when opening the left and right door bodies connected by the central hinge etc. so that they overlap, the handles attached to the adjacent vertical stile will come into contact with each other.
It is not possible to open the stiles very close together,
Therefore, there was a problem in that the width of the opening through which a person could pass when opening the folding door could not be made very wide.On the contrary, if the distance between the grip part of one handle and the vertical stile was narrowed,
The handle becomes difficult to grip and operability deteriorates.

The present invention aims to solve these problems.

That is, it is an object of the present invention to provide a handle for a folding door having a structure that allows a sufficient distance between the grip portion of the handle and the vertical stile, and also allows for a wide opening when the folding door is opened.

(Means for solving the problem) In order to achieve this object, the handle of the folding door according to the present invention has the following features:
For installation on the stile of a folding door, attach one handle to the fixture so that it can rotate freely in the direction of the panel surface, and can be raised freely in the direction outside the surface of the panel.
The above-mentioned attachment of the handle to the tool includes a spring provided at the base that always biases the handle toward the panel, and the above-mentioned attachment is such that the grip base fits into the contact surface of the tool with the handle base when the handle is in a horizontal position. The handle is characterized by being provided with a concave portion into which the grip is inserted, and a raised portion on which the grip base rides to raise the handle when the handle is in a vertical position.

(Function) Since the present invention has the above-described structure, when the handle is oriented vertically, the base of one handle comes into contact with the protruding part of the tool and the handle is raised, and there is a gap between the handle and the frame. If the handle is turned sideways, the base of the handle will come into contact with the recess of the fitting due to the force of the spring, and this will bring the handle closer to the door body.

(Embodiment) FIG. 1 is a cross-sectional view showing an embodiment of a folding door using a handle according to the present invention, and FIG. 2 is a front view of the folding door viewed from the indoor side. This folding door has two door bodies 1.2 mounted within a frame consisting of upper and lower frames 3, 4 and side frames 5 made of aluminum profiles or the like.

Each door body 1.2 is constructed by fitting a panel 9 into a framework made of upper and lower frames 6.8, left and right vertical frames 7, and an inner frame 10 as needed. . The vertical stile 7 at the butt part of both door bodies 1 and 2 is butterfly $11A.
The other vertical stile 7 of one door body l is connected to one vertical frame 5 by a hinge 11B, and the other vertical stile 7A of the other door body 2 is connected to the other vertical stile 7A. Hinge II
At the upper end of the vertical stile 7A, a hanging wheel 14 is attached which moves along the rails of the upper frame 3 in the same way as a normal folding door, and at the lower end there is a pivot that slides along the rails 13 of the lower frame 4. 15 is installed.

- Vertical stile 7 at the butt part of door body l on one side and door body 2 on the other side
A handle 16 according to the present invention is attached to the handle. The structure of the attachment of the handle 16 will be explained with reference to FIGS. 3 to 6. FIG. 6 is a perspective view showing a fitting 17 for attaching the handle 16, and the fitting 17 is made of metal or plastic.

The upper and lower parts have through-holes 18 for mounting, a circular hole 19 is provided in the center, and a cylindrical raised part 20 with an inner diameter slightly larger than that of the circular hole 19 is formed on one side. It has four parts 21 formed by cutting out, and the other side is integrally provided with a square part 23 having a circular hole 22 slightly larger than the circular hole 19, as shown in the longitudinal cross-sectional view of FIG. The square portion 23 is fitted into the square hole 24 provided on the outer surface a of the vertical stile 7, and a fixing device 25 such as a screw is inserted into the through hole 18 to close the hole 26 of the vertical stile 7.
It is fixed to the stile 7 by being connected to the stile 7.

The handle 16 is attached to a rotating body 28, as shown in the exploded perspective view of FIG. Tool 1
The cylindrical portion 31 that fits into the circular hole 19 of No. 7, and the raised portion 20
A cylindrical portion 32 that fits into the cylindrical portion 32, and a flange portion 3 provided on the cylindrical portion 32.
3, a part of the cylindrical part 32 and the collar part 33 are removed,
Insert the base 16a of the handle 16 through the cut fi34,
The handle 16 is rotatably attached to the cylindrical portion 32 around a shaft 35, and a coil spring 36 is wound and attached to the shaft 35.
Accordingly, the handle 16 is biased in the direction of the arrow.

As shown in FIGS. 3 and 5, this handle 16 is installed by fitting a rotary body 28 into a tool 17, and fitting a wear-resistant washer 38 into a circular hole 22 on the side of the square part 23 of the tool 17. A locking metal fitting for a female screw 40 having a square hole 42, on which a female screw 40 is stacked by being screwed into a threaded cylindrical portion 30, and a recess 41 into which a protrusion 39 of the female screw fits is formed on the outer periphery. 43
is attached by fitting the square hole 42 to the square bar 29, and on top of that, two elastic plates 44 that sandwich the square bar 29 from both sides are pushed into the notch 45 of the square part 23, and fixed. The plate 46 is attached by rotatably inserting the square rod 29 into the circular hole 47 at the center thereof, inserting the screw 48 into the peripheral through-hole 49, and screwing and fixing it into the screw hole 50 of the square part 23.

When this handle 16 is turned sideways as shown in the solid line in FIG. 4 and in FIG. 1, the base lea of one handle 16 is
Due to the force of the coil spring 36, the attachment fits into the recess 21 of the tool 17, and the tip 16b of the handle 16 is located closer to the panel 9 than the outer surface a of the vertical stile 7. 2, as shown in FIG. 1, the protruding width Ll of the handle 16 from the door body 2 becomes small. Therefore, the interval Wt between the door bodies when the folding door is opened can be narrowed, and the rMn portion @W+ can be widened.

Furthermore, as shown by the two-dot chain line d in FIG. 4 and the solid line d in FIG. Place it on the raised portion 20h. As a result, a large gap L2 is formed between the first handle 16 and the vertical stile 7, and the fingers of the hand can be easily inserted between the gaps, resulting in good operability. In addition, in FIG. 3, for comparison, a state in which one handle 16 is placed sideways is shown with two-dot chain lines overlapping each other. In addition, since the square bar 29 is held between the two elastic plates 44, its posture can be easily maintained and stabilized in the vertical and horizontal states.

The present invention has been described above with reference to embodiments, but in the present invention, not only one panel 9 but a plurality of panels may be attached, and the handle 16 may be attached to the center lO.
In addition, in the embodiment, if it is necessary to attach a handle to the surface opposite to the surface on which grip 1=F and 1B are attached, the handle may be attached coaxially with the handle 16 so that it interlocks with the handle.

It goes without saying that various changes and additions can be made to the specific structures of the other handle 16, attachment tool 17, etc., and their combinations, without departing from the gist of the present invention.

(Effects of the Invention) According to the present invention, when the handle is in a vertical position, the base of the handle comes into contact with the protrusion of the mounting tool and is raised, thereby ensuring a sufficient distance between the handle and the frame. The operability is improved because it can be used for various purposes.

In addition, if one handle is placed sideways, the base of the handle will come into contact with the recess of the mounting tool due to the force of the spring, and this will bring the handle closer to the door body side, so the protrusion width of one handle will be smaller, and when the folding door is opened, The interval between the door bodies can be narrowed, the opening width can be widened, and the mounting width is narrow, making it possible to provide a folding door with a wide opening width.
