Description

  The present invention relates to a swing-type door that opens and closes using one vertical rod of a panel body as a rotating body.

  The free door that opens to either the inside or the outside can be opened by pushing the door panel from the indoor side or the outdoor side. Therefore, the operation of pulling the door panel is unnecessary, and even when both hands are covered with luggage, the door can be opened simply by depositing the body on the door panel, which is very convenient. This is also advantageous for disabled people who are forced to move in a wheelchair.

  In such a free door, like a normal single door or double door, make sure that the door panel goes too far to the opposite side when the door opens along the three-way frame of the door. Since the door stop to prevent cannot be provided, a clearance gap inevitably arises between a vertical gutter and a vertical frame, and a horizontal gutter and a horizontal frame. In addition, light and sound from the gap and a door facing the outdoors have a problem in shielding properties such as wind and rain leaking.

  As a solution to this problem, the folding door is configured to open to both the inside and outside by aligning the rotation center position with the position on the center axis passing through the center point in the thickness direction of the door panel. There is a device that attaches a gap sealing material made of a member having elasticity such as mohair, rubber, beet (synthetic rubber), etc. to one of the vertical hooks and tries to close the gap (for example, see Patent Document 1). .) However, even if such a gap sealing member is attached, the shielding performance is not perfect.

  On the other hand, when closing a hinged door, there are many accidents in which a finger is caught between a vertical frame and a vertical fence. In particular, a normal door that has a rectangular parallelepiped door panel having a rectangular cross section and a vertical frame having a rectangular cross section that is pivotally supported using a hinge is likely to pinch a finger, and there is a high risk of a serious accident.

On the other hand, in the folding door disclosed in the above-mentioned Patent Document 1, the end of the door panel is formed in an arc shape, and the rotation center position is aligned with the position on the central axis passing through the center point in the plate thickness direction of the door panel. Therefore, a large gap does not occur even when the door is open, and the structure is such that it is difficult to pinch fingers. Nevertheless, there is no possibility of having a finger in the narrow gap.
JP-A-9-273350

  The present invention has been made in consideration of the above-described circumstances, and provides a swing type door that has improved shielding properties such as light and sound even if it is a door that cannot be attached to a door such as a free door. It is intended.

  Another object of the present invention is to provide a swing type door that does not have a finger pinched between the vertical frame and the suspension side downboard when the door is closed.

  In order to solve the above-described problem, the swing type door according to the present invention is a swing type door provided with an opening / closing door provided in a frame forming an opening of a building as described in claim 1. The door body includes a rotating body having a circular cross section and rotating around the center of the arc, and a door panel fixed to the rotating body, and the frame body facing the rotating body. The vertical frame is provided with a recessed portion in which the arcuate rotating body can be rotatably fitted.

  According to this invention, even if it is a door which cannot attach a door stop like a free door, shielding properties, such as light and a sound, can be improved. In addition, the present invention provides an effect that a finger is not sandwiched between the vertical frame and the suspension side downboard when the door is closed.

  An embodiment of a swing type door according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing an overall outline of a first embodiment of a swing type door according to the present invention, FIG. 2 is a view of the swing type door shown in FIG. FIG. 4B is a partial cross-sectional view at the time of opening.

  The swing type door 1 according to this embodiment uses a single door, and is formed as a free door that can be opened to either the inside or outside.

  As shown in FIG. 1, the three-sided frame body 2 and the floor surface 5 define an opening OP that forms a room entrance. The three-way frame 2 is formed by integrally forming an upper frame 3 and vertical frames 4 and 4 on both sides thereof. A swing type door according to this embodiment is attached to the inside of the three-way frame 2.

  In the swing type door 1, the door body 6 is fixed to the rotating body 9 via a mounting bracket 11, and a rotating body 9 having a circular cross section and rotating around the center of the arc. The door panel 10 is formed.

  Among these, the door panel 10 forms a main part of an opening / closing body that opens and closes the opening OP, and the length in the width direction is set to a size sufficient for opening and closing. The material of the door panel 10 is made of wood in this embodiment.

  Here, the material of the rotator 9 is made of metal in order to obtain sufficient rigidity to support the door panel 10, but is not necessarily limited thereto.

  In FIG. 1, an upper pivot 7 is fixedly provided in an end of the upper frame 3 in the suspension base side of the door body 6, while a lower pivot 8 is embedded on the opposite floor surface 5 directly below the upper pivot 7. The The upper pivot 7 has a pivot structure, and its shaft is detachably connected to a bearing on the upper end surface of the rotating body 9.

  A door panel 31 is screwed to the upper end surface of the rotating body 9 via a mounting bracket 11. On the other hand, the door panel 10 is screwed to the lower end surface of the rotating body 9 via a mounting bracket 11. The bearing on the lower end surface of the rotating body 9 is detachably attached to the shaft of the lower pivot 16. As described above, the door panel 10 is sandwiched and fixed between the upper and lower mounting brackets 11 and 11.

  On the other hand, the vertical frame 4 on the suspension base side of the door body 6 is formed with a recessed portion 4a from which the arcuate rotating body 9 can be rotatably fitted, as shown in FIG. . The recessed portion 4a is further provided with a recessed groove 4b from the upper end to the lower end. A gap sealing material (rubber, mohair, etc.) 12 is attached to the concave groove 4b.

  Since the swing type door 1 according to this embodiment is configured as described above, even when the door shown in FIG. 2 (a) is opened, or when the door shown in FIG. 2 (b) is closed. However, the light inside the room does not leak from the gap between the vertical frame 4 and the rotator 6, and the shielding is improved. Further, since the gap between the vertical frame 4 and the rotating body 6 is very small as compared with the case where the vertical frame is a rectangular parallelepiped shape, there is almost no possibility of pinching a finger here. Furthermore, by providing the gap sealing material 12, the shielding performance against sound and the like is improved.

  In addition, since the notch part 6a is provided in the connection part of the rotary body 9 of the door body 6 and the door panel 10, the corner part of the vertical frame 4 and the door body 6 interfere even when the door is opened. The door 6 can be fully opened up to 90 °.

  Next, a second embodiment of the swing type door according to the present invention will be described with reference to FIG. 3A is a partial cross-sectional view of the second embodiment of the swing type door according to the present invention when closed, and FIG. 3B is a partial cross-sectional view when opened.

  The connecting member 13 has a length over the entire length from the upper end to the lower end of the door pair 6, and the connecting member 13 in which the door panel 10 is fixed between the two extending portions 9 a and 9 a extending from the rotating body 9. Is fixed to the rotating body 6.

  Thereby, the effect equivalent to that of the swing type door according to the first embodiment can be obtained even in the aluminum or wooden hollow flush door.

  Next, a third embodiment of the swing door according to the present invention will be described with reference to FIG. FIG. 4A is a partial cross-sectional view when the swing type door according to the second embodiment of the present invention is closed, and FIG. 4B is a partial cross-sectional view when the swing door is open.

  As shown in the figure, the swing type door of the present embodiment is basically different from that in the first embodiment in that the door panel 10 is a coffin door, and other configurations are the same as those in the first embodiment. Since they are substantially the same, the same reference numerals are given and description thereof is omitted.

  In the same figure, 10a is a vertical gutter and 10b is glass. 10b may be a rigid resin or a wood panel instead of glass. In this case, the vertical rod 10 a is formed integrally with the rotating body 9. Since the glass 10b is thinner than a flash door or the like, the door can be provided without providing the notch 6a as in the first embodiment, as long as the width necessary to hold the glass in the collar is secured. At the time of opening, the corner portion of the vertical frame 4 and the door body 6 do not interfere with each other.

  Thus, according to the swing-type door according to the present embodiment, the same effect as that of the swing-type door according to the first embodiment can be obtained even in the case of a sliding door such as a glass door.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.

  For example, in the above-described embodiments, the explanation has been given by taking a single door as an example. However, the swing type door according to the present invention is not limited to a free door, but may be a double door or a folding door. be able to.
