Description

[Detailed Description of the Invention] This invention relates to a sliding door with a hinge mechanism that can not only be opened and closed in a sliding manner by reciprocating the door body, but also opened and closed in a hinged manner by horizontally rotating the door body. It is.

Conventionally, various types of doors have been proposed.

For example, the one disclosed in Japanese Patent Publication No. 49-43030 has a rail 1 as shown in Figure 1.
A substantially inverted U-shaped frame 102 is fixed to a door roller mechanism 101 that can run in forward and reverse directions along 00, and this frame 102
One end of the door body A fitted into the frame was horizontally pivotably connected to the frame by a pair of upper and lower bearing mechanisms 103 and 104. However, according to this document, if the width of the door body A is wide or the width of the door body A is wide,
When the weight of the door body A is heavy, a large rotational load is applied to the frame body 102, and the frame body 102 deforms as shown by the broken line in the figure, causing the free end of the door body A to droop, making it impossible to open and close the door body A smoothly. Something happened.

In order to solve this problem, the amount of deformation of the frame 102 due to the rotational load is taken into account in advance, and when the weight of the door A is added to the frame 102, the frame 102 is
A frame body 1 having a shape that can prevent the free end of the door body A from hanging down when the frame body A is in a deformed state.
It is possible to use 02. For example, the second
As shown in the figure, the upper corner angle θ of the frame 102 is set to an angle of 90 degrees or less, and when the weight of the door body (not shown) is added to the frame 102, the corner angle θ becomes 90 degrees. It is possible to do so. However, the amount of deformation of the frame differs depending on the weight and width of the door, so in order to adopt the above method, it is necessary to use a frame with a different corner angle θ depending on the weight and width of the door. It is necessary to prepare the following materials, which has the drawback that it is unsuitable for mass production.

In addition, as shown in FIG. 3, Japanese Patent Laid-Open No. 58-65886 discloses that one end of the door body A is attached to a bearing mechanism 20 in a door roller mechanism 201 that can run in forward and reverse directions.
2 so that it can be horizontally rotated, and this door body A
A support rod 203 is installed between the upper end of the door body A and the door wheel mechanism 201 to prevent the free end from sagging. However, in this case, the support rod 203 needs to have extremely high bending strength, and the attachment structure between the support rod 203 and the door body A or the door wheel mechanism 201 needs to be strong. Therefore, there are drawbacks such as an increase in storage space and a rise in price.

Furthermore, in the case of conventional sliding doors with a swinging mechanism, one end of the door body is supported by a bearing mechanism, so when the door body is opened in a swinging manner, the width of the door protruding from the frontage is limited. It becomes wider and equal to the total width of the door body. For this reason, there were cases in which the door body, which was opened in a swinging manner, obstructed access to the outside.

This invention was made to improve the above-mentioned circumstances and shortcomings, and allows the door body to be opened into a hinged door regardless of the weight or width of the door body, and without using any extra members to support the door body. To provide a sliding door with a hinge mechanism, in which the door body is supported in a state where the free end does not sag when the door is opened, and which does not impede outside traffic as much as possible when the door is opened.

The technical means to achieve the above purpose is to form a rail in the width direction of the frontage in the gap provided above the entrance, support the main door wheel mechanism that can run in forward and reverse directions on this rail, and The door roller mechanism is provided with a rail portion extending in the same direction as the rail, a movable auxiliary door roller mechanism is supported on the rail portion, and a widthwise center portion of the door body is connected to the auxiliary door roller mechanism so as to be horizontally pivotable.
That's true.

According to this technical means, the center part of the door body in the width direction is supported so that it can rotate horizontally, so that the free end of the door body does not hang down, regardless of the weight or width of the door body. In addition to being able to open and close the door, there is no need to attach any extra parts to prevent the free end from sagging as mentioned above, and the protruding width of the door when opened in a swinging manner is the same as the total width of the door. This will reduce the traffic to around half of that, and will no longer pose an extreme hindrance to external traffic.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 11. In the following explanation, the door bodies A and B shown in the left half of Fig. 4 will be explained, and the door bodies A and B shown in the right half of the figure are given the same reference numerals because they are the same. Therefore, detailed explanation thereof will be omitted.

In the sliding door with a swinging door mechanism illustrated in FIG.
and so-called snap-in type door bodies B are arranged symmetrically in pairs. As shown in the figure, a rail 1 is installed horizontally over almost the entire width of the upper part of the frontage, and a main door mechanism 2 equipped with a pair of left and right door hangers 21, 21 can run forward and backward on this rail 1. is supported by The main door roller mechanism 2 also includes a rail-shaped frame 22 that connects the pair of door hangers 21, 21, and this frame 22 accommodates a sub door roller mechanism 3 that can run forward and backward in the same direction as the main door roller mechanism 2. . That is, as shown in detail in FIG. 5, the frame 22 is constituted by a hollow square member having a pair of rail surfaces 22b, 22b on both sides sandwiching the bottom opening groove 22a shown in FIG. On the other hand, the secondary door roller mechanism 3 is equipped with wheels 32, 32 at both left and right ends of a frame 31 made of square timber, and these wheels 32 are connected to an eighth wheel.
As shown in the figure, it is configured to be supported on the above-mentioned rail surface 22b.

Next, as clearly shown in FIG. 4, a support shaft 4 is vertically attached to the center of the upper end surface of the door body A, and this support shaft 4 is rotatably connected to the above-mentioned sub-door wheel mechanism 3. That is, as shown in detail in FIGS. 5 and 7, the support shaft 4 is integrally fixed to a metal fitting 41 bolted to the upper frame a of the door body A, and the frame 22 shown in FIG. Bottom opening groove 2
A nut 42 is inserted through the bearing hole 31a formed in the frame 31 of the sub-door roller mechanism 3 through the nut 2a and screwed into the upper end of the support shaft 4, and is locked to the frame 31 through the washer 43 in the removal direction. There is.
Furthermore, as is clear from FIG.
Two parts displaced by 180 degrees are processed into a flat shape to form flat parts 44, 44. In addition, the main door wheel mechanism 2
A stopper 5 is fixed to the frame 22 of. As clearly shown in FIG. 6, this stopper 5 has an engaging hole 51 having approximately the same diameter as the diameter of the above-mentioned support shaft 4, and a width dimension l ₀ smaller than the diameter of this engaging hole 51.
A notch hole 52 is provided. Here, cutout hole 5
The width dimension l ₀ of 2, the flat portion 44, 4 of the above-mentioned support shaft 4
4 and the width dimension of the bottom opening groove 22a of the frame 22 are configured to be almost the same, and when the door body A is closed in the center of the above-mentioned frontage, as shown in FIG. The support shaft 4 fits into the engagement hole 51 of the stopper 5 and is locked in the left-right direction, while the door body A is opened like a hinged door in the center of the frontage, as shown by the imaginary line 4a in the figure. As described above, the support shaft 4 is configured to be easily removed from the engagement hole 51 through the notch hole 52. As shown in FIG. 4, a guide roller 61 is attached to the lower end of the door body A so as to be coaxial with the support shaft 4. It is now possible to drive without causing any problems. These guide rollers 61 and guide rails 62 form a lower end guide mechanism 6 of the door body A.

On the other hand, as shown in FIGS. 4 and 5, the upper end of the door body A has two locations sandwiching the attachment position of the support shaft 4 and the frame 22 of the main door wheel mechanism 2 mentioned above.
Positioning and holding mechanisms 7 and 8 are interposed between them, respectively. As shown in FIG. 8, one of the positioning and holding mechanisms 7 includes a pair of upper and lower U-shaped engaging fittings 71a, 7 that can be fitted into and removed from each other.
1b, of which the upper engaging fitting 71
While a is fixed to the frame 22 side,
A lower engagement fitting 71b is fixed to the door body A side. Also, the other positioning and holding mechanism 8 is similar to the above.
It is composed of a pair of upper and lower U-shaped engagement fittings that can be fitted and removed from each other, and as is clear from FIG. The direction of engagement and disengagement with the lower engagement fitting 81b is opposite to that shown in FIG. Next, as for the door body B explained in FIG. 4, one end thereof is supported at the end of the frontage by a pair of upper and lower bearing mechanisms 9, 9 so as to be able to rotate horizontally, as schematically shown in the same figure. has been done. In addition, a latch (not shown) is provided at a predetermined location on the other end of the door body B.
Due to the action of this latch, the door body B is configured not to open easily even if it is subjected to an external force such as a breeze.

In addition, in FIG. 5, 10 indicates a rubber door stop.

Next, the operation of the present invention having the above configuration will be explained.

For example, as shown in Figure 10, door body A and door body B
From the state where the frontage is closed, draw the door body A on an imaginary line.
A If you want to open the central part of the frontage by sliding the door to the position shown in ₁ , start the drive mechanism (not shown) and open the fourth door.
The main door wheel mechanism 2 explained in the figure is made to run in the forward direction along the rail 1. In this case, one of the positioning and holding mechanisms 7 has a pair of upper and lower engaging fittings 71a and 71b that engage with each other in a meshing manner, as shown in FIG.
The other positioning and holding mechanism 8 also has a pair of upper and lower engaging fittings 81a and 81b that mesh with each other as shown in FIG. does not open like a hinged door. In addition, a support shaft 4 connected to the sub door wheel mechanism 3
As shown in FIG. 6, the auxiliary door wheel mechanism 3 is positioned relative to the main door wheel mechanism 2, and the door body When A is opened in a sliding door manner, the auxiliary door wheel mechanism 3 is prevented from unnecessarily traveling along the frame 22. In addition, the main door mechanism 2
If it runs in the opposite direction along rail 1, door body A
Of course, it can be closed like a sliding door.

Next, when opening the frontage completely from the closed state with door body A and door body B as shown in Figure 10, move door body B as shown by imaginary line _B1 in the figure. Opens 90 degrees using the bearing mechanism 9 as a fulcrum,
At the same time, the door body A is opened 90 degrees in a swinging manner around the support shaft 4 as shown by the imaginary line _A2 in the same figure, and then the main door wheel mechanism 2 and the sub door wheel mechanism 3 are both moved in the forward direction. Move it to the position of virtual line A ₃ . In this case, when the door body A is opened in a swinging manner as shown by the imaginary line _A2 in the same figure, the door body is moved by the positioning and holding mechanisms 7 and 8 explained in FIGS. 4, 5, 8, and 9. The positioning state of is released, and at the same time, the support shaft 4 faces the cutout hole 52 of the stopper 5 and can be easily removed from the engagement hole 51, as shown by the imaginary line 4a in FIG. Therefore, the positioning state of the auxiliary door roller mechanism 3 with respect to the main door roller mechanism 2 is released, and the auxiliary door roller mechanism 3 can now be moved in the forward direction along the frame 22. Further, when the sub door roller mechanism 3 is run in the forward direction along the frame 22, the flat portions 44, 44 of the support shaft 4 slide against the notch hole 52 of the stopper 5 or the wall surface of the lower opening groove 22a of the frame 22. Since it is guided, the door body A is the pivot 4
It will not swing unnecessarily around this point. Furthermore, when the door body A is opened like a hinged door, the width of the protrusion from the frontage of the door body A is the imaginary line in Figure 10.
As is clear from A ₂ and A ₃ , it is about half of the total width of door A, so it is about half that of the conventional type that opens from one end of door A. It can be shrunk. Therefore, when the door body A is opened like a swinging door, it will not cause an extreme hindrance to outside traffic. In addition, since the door body A is horizontally pivoted about its widthwise central portion as a fulcrum, its free end will not sag, regardless of its weight or width. Furthermore, since the door body _A3 can be moved to the position and brought into close contact with the door body A3, the space between the two pillars P, P, that is, the frontage is wide open, making it easier to pass through.

Furthermore, when the door body B is opened 90 degrees in a swinging manner as shown by the imaginary line _B1 in Figure 10, the width of the protrusion from the frontage of the door body B is almost equal to its entire width, so the door body B There is a risk that external traffic will be hindered. In this case, if the door body B is made to open 180 degrees like a swinging door as shown by the imaginary line _B2 in FIG. 11, this possibility can be eliminated.
