[0011]

However, in the case of the door based on the slide-swing operation described in the various publications described above, the door (door body, In the state of opening and closing the panel body), a supporting member (an arm hinge, etc.) that supports the door so that it can rotate (swing) freely, and a door upper frame member (a door upper frame or a decorative cover of the door upper frame). Between, and between the door frame side end that rotatably supports the door and the door side end, since a gap that changes in size according to the degree of opening and closing respectively occurs. In particular, when the door was closed, there was a risk that a finger or an object would be caught in this gap. Also, if the door is forcibly closed with an object interposed therebetween, the door may be damaged.

The present invention has been made in view of the inconvenience of such a conventional slide-swing type door device. When the door is closed, the door body, the supporting member, and other members and structures are provided. In addition to preventing or suppressing the occurrence of a state in which a finger or an object is pinched in the gap with, and even if a finger or an object is pinched, a large stress should not be applied to this. With that purpose.

[0013]

In order to achieve the above object, a sliding and swinging type door device according to the present invention comprises:
A door body for opening and closing an opening defined by a door frame, and both ends are respectively pivoted between a predetermined position of the door body and a predetermined position in the vicinity of the door frame or the door body, and the door body is An arm hinge that supports a horizontally rotatable support, and a slide support that is attached between the door frame and the door body and that supports the door body slidably with respect to the door frame in the width direction of the opening. When the door body is closed while sliding and swinging based on the arm hinge and the slide support, an object is sandwiched in a gap formed by at least one of the arm hinge and the door body. The main configuration is to provide a mechanism for preventing the occurrence of an object or reducing an impact when an object is caught in the gap.

For example, in the arm hinge, one end of the door frame is positioned above one side end of the door frame, and the other end of the arm hinge is positioned at an upper end surface of the door body. An upper arm hinge at a predetermined position, wherein the mechanism is attached to an upper end of the door frame, and the upper frame and the tip of the upper arm hinge facing the tip of the upper arm hinge when the door body is closed. This is a mechanism for preventing an object from being caught in a gap formed therebetween, or reducing an impact when an object is caught in the gap.

In this case, a preferred example is a structure constituting the mechanism, wherein the tip of the upper arm hinge is formed to have a curved surface. Further, the mechanism may have a structure in which a cushioning material is attached to the tip of the upper arm hinge. Furthermore, the mechanism may be a screen mechanism that covers a gap between the tip of the upper arm hinge and an end of the upper frame, and that can expand and contract with the opening and closing of the door body. Furthermore, the mechanism may be a mechanism that bends a part of the upper arm hinge on the side of the tip when a shock equal to or more than a predetermined value is applied. As still another preferred example, the mechanism is a mechanism that is disengaged when an impact of a predetermined value or more is applied to a part of the upper arm hinge on the tip side.

In the main structure, the arm hinge has a pivotal position at one end above a side end of the door frame and a pivotal position at the other end of the door frame. Including an upper arm hinge which is a predetermined position on the upper end surface of the body,
The mechanism prevents an object from being caught in a gap formed between a side end of the door body on the side where the upper arm hinge is attached and one side end of the door frame facing the side end, or It is also preferable to provide a mechanism for reducing an impact when an object is caught in the gap.

In this case, as a structure forming the mechanism, for example, the end face of the side end of the door body is formed to have a curved surface. Further, the mechanism may have a structure in which a cushioning material is attached to the side end of the door body. Further, the mechanism may be a screen mechanism that covers a gap between the side end of the door body and the side end of the door frame and that can expand and contract with the opening and closing of the door body. . Furthermore, the mechanism may be configured as a mechanism that bends like a folding door when a part of the side end of the door body receives an impact of a predetermined value or more.

Still further, in the above-mentioned main construction, the arm hinge has a pivot position at one end located above one side end of the door frame and a pivot position at the other end. An upper arm hinge which is a predetermined position on an upper end surface of the door body, wherein the slide support is pivotally attached to a guide rail attached to an upper end portion of the door frame and another predetermined position on an upper end surface of the door body. And a traveling tool slidable in the guide rail, and the mechanism further applies a force of a predetermined value or more to connect the upper arm hinge or the traveling tool to the upper end surface of the door body. It is also a preferable example that the mechanism is a detachment mechanism that is sometimes detached.

Further, in each of the various configurations described above, the positions at which both ends of the arm hinge are attached to the door frame and the door body are set at the center position or substantially the center position in the thickness direction of the door body. Can also.

Further, in the above-mentioned main structure,
A groove-shaped rail that assists sliding of the door body is laid on a floor surface that defines the opening along with the door frame, and the arm hinge has a shaft attachment position at one end of the door frame. The mechanism includes a lower arm hinge at a predetermined position on the grooved rail near the lower end of one side end, and a shaft attachment position at the other end is a predetermined position on a lower end surface of the door body. Alternatively, at least a portion of the arm portion of the lower arm hinge may be offset from the position of the groove-shaped rail in the direction of the opening / exit of the opening.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A slide-swing type door device according to a first embodiment of the present invention will be described with reference to FIGS.

The door device according to this embodiment uses a door panel as a single door body, and slides and opens and closes the door panel by sliding and swinging the door panel.
The swing method (manual method) is adopted.

In the following description, the width direction of the opening for opening and closing the door panel is simply referred to as “width direction”, and the vertical (vertical) direction of the opening is simply referred to as “vertical direction”, if necessary.
And the direction orthogonal to the opening surface of the opening is simply referred to as the
And correspond to the directions of the X, Y, and Z axes shown in FIG. 1, respectively.

This slide-swing type door device is shown in FIG.
As shown in FIGS. 3 to 3, one door panel 11 as a door body
A three-sided frame body 12 (door frame), which is opened and closed by the door panel 11 and cooperates with the floor surface F to define the opening OP, an outer facing door 13, an inner facing 14, The upper suspension rail 15 (see FIG. 4) formed in the three-sided frame body 12, the lower guide rail 16 buried in the floor surface F, and the inner and outer decorative covers 17, 1 above the opening.
8 is provided.

The door panel 11 has a substantially rectangular shape having a predetermined thickness, and has a size corresponding to the opening OP of the door installation position.
Is formed so as to fit into the rectangular shape with an appropriate margin. As the material of the door panel 11, an appropriate material such as wood, metal such as aluminum, resin, and glass can be used. Knobs 23a and 23b are attached to the door panel 11 at predetermined positions inside and outside the room.

A side end face of the door panel 11 on the other side (hereinafter referred to as a hanging side) on which an arm hinge described later is installed has a roundness 11a so that its cross-sectional shape draws a semicircle (curved surface). I'm making it. The roundness 11 a is one of the features of the present invention, and prevents a situation where a finger or an object is caught between the door panel 11 and the side frame 12 a of the frame 12 when the door panel 11 is closed. Intended.

An upper arm hinge 30A and a lower arm hinge 3 are provided at predetermined positions on the upper and lower ends of the hanging side of the door panel 11.
OB are each mounted in a so-called "offset-less" configuration. The door panel 11 can swing with respect to the opening OP via the arm hinges 30A and 30B.

Here, the "offset-less" structure is as follows.
The structure in which the arm of the arm hinge is mounted so as to fit within the width in the thickness direction of the door panel is referred to as such. On the other hand, a structure in which the arm hinges are attached to the side positions of the upper and lower ends of the door panel is called an "offset" structure in the sense that the arm hinge is offset from the plate thickness position of the door panel.

The upper arm hinge 30A is formed of, for example, an aluminum material, but the type of the material is not particularly limited. As shown in FIG. 5, the upper arm hinge 30A includes an arm 31 having a predetermined length and thickness and formed in a long plate shape. The first and second ends of the arm 31 are rotatable with respect to a direction perpendicular to the longitudinal direction and along the arm surface.
Second mounting portions 32 and 33 are formed respectively.
In other words, the first mounting portion 32 is provided at the base end of the side frame 12a, and the second mounting portion 3 is provided at the opposite end.
3 is located.

The reason why the arm 31 is formed in a long single plate shape is as follows.
The door panel 11 cooperates with a six-wheel slide roller described later.
This is because the door panel 11 can smoothly swing while supporting almost the entire load. As described later, the thickness of the arm 31 in the thickness direction is set so that the surface of the arm 31 and the upper inner decorative bar 17 located on the indoor side can be matched as much as possible in order to improve aesthetic appearance.

One of the features of the arm 31 relating to the present invention is that the side surface of the tip of the arm 31 is rounded.
1a. Specifically, the cross-sectional shape in a direction orthogonal to the surface direction of the arm 31 is a semicircle. The roundness 31 a prevents a situation in which a finger or an object is caught between the arm 31 when the door is closed and the side end of the inner decorative bar 17.

The first mounting portion 32 located at the base end includes:
It has a structure in which a bearing 32b is protruded from a substrate 32a, and the substrate 32a is embedded in the side frame 12a of the frame 12. The bearing 32b protruding in the lateral direction is housed in the cutout KB of the arm 31, and the arm 31 and the bearing 32
b is rotatably supported by a rotating shaft 32c penetrating in the vertical direction. As a result, the arm 31 is rotated
It becomes rotatable in a horizontal plane about 2c.

As shown in FIG. 8 described later, the position of the rotating shaft 32c is shifted to a position near the frame in the opening width direction so that the rotating shaft 32c itself does not interfere with the door panel 11 when the door is fully opened. And by this,
An "offset-less" construction of the upper arm hinge 30A is possible.

On the other hand, the second mounting portion 33 at the tip of the arm
Are the bolt 33a, the nut 33b, and the mounting base material 3.
3c. One end of the bolt 33a has an arm 3
1 is rotatably mounted on the lower surface of one end, and the other end is fixed to the mounting base 33c with a nut 33b.
The mounting base 33c is embedded in the upper end surface of the door panel 11. The embedding position is a position that is １ ／ or approximately １ ／ of the width of the door panel 11 in the width direction. This allows the arm 31 to be rotatable in the horizontal plane with respect to the door panel 11 about the bolt 33a.

The suspension shaft (bolt 33) of the second mounting portion 33
The reason that the position a) is set to 1/3 or approximately 1/3 of the width in the width direction of the door panel 11 is to swing the door panel 11 smoothly and to minimize the force required for opening and closing the door. is there.

As described above, the door panel 11 is rotatable in an "offset-less" state from one of the side frames 12a of the frame 12 via the upper arm hinge 30A at an upper position of the side end on the hanging side. It is suspended (see FIG. 6).

As shown in FIG. 4, an upper suspension rail 15 is formed integrally with the upper frame 12b, which is a part of the three-sided frame 12, in the center of the upper and lower directions in the entering and exiting directions. A six-wheel slide roller 40 as a traveling tool is slidably accommodated in the upper suspension rail 15. The slide roller 40 has a roller body 40a and a shaft 40b, and the shaft 40b is mounted on a predetermined position on the upper end surface of the door panel 11. This shaft attachment position is preferably a distance of 1/3 or approximately 1/3 from the rotation side end of the door panel 11. The shaft 40b is rotatable with respect to the roller body 40a.

As shown in FIGS. 3 and 4, the above-described inner decorative bar 17 is mounted on the indoor side with the same height as the upper arm hinge 30A. In order to allow the upper arm hinge 30A to rotate, the length of the inner decorative bar 17 in the opening width direction is reduced as shown in FIG. On the other hand, as shown in FIGS. 3 and 4, the outer decorative bar 18 is aligned with the upper arm hinge 30A in height and has both side frames 12a,
It is erected between 12a in a fixed state. The length of the outer decorative bar 18 extends over the entire width of the opening OP.

On the other hand, a guide rail 16 is buried at a position facing the three-sided frame 12 on the floor surface. As shown in FIG. 7, a lower arm hinge 30B is attached to a suspension side of the guide rail 16 directly facing the upper arm hinge 30A described above. This lower arm hinge 30B is
It has an elongated and thin plate-like arm 30Ba, and at both ends thereof, rotating shafts 30Bb and 30Bc which are opposite to each other are erected.

The lower arm hinge 30B is "offset-less" which fits entirely within the thickness of the door panel 11.
Although the arm 30Ba is mounted in a structure, the arm 30Ba itself has an "offset arm" shape so that the arm 30Ba can be attached at a position shifted from the position of the groove 16a of the guide rail 16. That is, the arm 30Ba is formed in an elongated U-shape from both ends thereof, and is disposed such that the bent arm portion is located on the indoor side.

The reason why the arm 30Ba is formed as an offset arm is that the groove 16a and the arm 3 when the door is closed.
This is for preventing a finger or an object from being pinched between 0Ba.

One pivot shaft 30Bb of the lower arm hinge 30B is rotatably mounted on a fixed plate 43 embedded in the end of the guide rail 16. Rotating shaft 30Bb
Is located on the side frame 12a so as not to obstruct the opening and closing of the door.
To the side. The other rotation shaft 30Bc is rotatably mounted on the door panel 11 at a predetermined position on the lower surface.
Both positions of the rotating shafts 30Bb and 30Bc are aligned with the rotating shafts 32c and 3 of the upper arm hinge 30A in the width direction of the door panel.
Each of them faces the position 3a.

A projection shaft 44 is provided on the lower end surface of the door panel 11 at a position directly opposite the shaft 40b of the six-wheel guide roller 40. The protruding shaft 44 slides in the groove 16 a of the guide rail 16 in the longitudinal direction thereof, and regulates the swing of the door panel 11 in and out of the door panel 11. A rotatable roller may be attached to the lower end of the projection shaft 44.

As described above, according to the present embodiment, the upper arm hinge 30A can be turned from the fully closed door position to the fully opened door position as shown in FIG. 8, or vice versa. The side arm hinge 30B can pivot from the fully closed door position to the fully open door position, as shown in FIG. 9, or vice versa. The lower arm hinge 30B can guide the door panel 11 along the trajectory of the opening / closing operation to make the sliding / swing operation of the door panel 11 smoother as its main function. Therefore, the entire door panel 11 can be smoothly and stably slid and swung in the direction from the fully closed state to the fully opened state or in the opposite direction to open and close.

As described above, all four points (the rotation axis positions of the upper and lower arm hinges, and the axis positions of the six-wheel slide roller and the projection shaft) supporting and locking the load of the door panel 11 are all on the panel. 1/3 or almost 1 / in the width direction
3 is set. Therefore, the user can slide and swing the door smoothly and lightly with the minimum necessary force to open and close the door. In addition, the main part of the load of the door panel 11 is supported by the upper arm hinge and the six-wheel slide roller,
In addition, since the lower arm hinge and the lower projection axis only guide the sliding and swinging operation of the door panel in a supplementary manner, unlike the door device having a structure that supports the load of the door panel only with the hinge, The door panel does not fluctuate during the sliding / swing operation, and the door panel does not shake due to wind pressure or the like when the door is closed, and the operation during opening / closing of the door and the door state when the door is closed become extremely stable.

In this open state of the door, as can be seen from FIGS. 8 and 9, only a part of the door panel 11 on the handle side comes out from the opening OP to the outside of the door, and the remaining part of the door panel 11 is on the indoor side. To be placed. In other words, the opening OP is uselessly closed when the door is opened only in the space of one door panel 11 in thickness, and the useless area occupied by the door thickness of the opening OP is minimized. . For this reason, unlike the conventional folding door, a plurality of door panels do not fold and occupy the opening, and the opening area required for access is not significantly reduced.

In addition, the door device of this embodiment has a simple configuration that only has an arm hinge for swing operation, a roller (shaft) and a guide (suspension) rail for slide operation. For this reason, it can be easily implemented not only in a commercial building such as a hospital or an office building, but also in a general residential house where space saving is required.

Further, when the door device of the present embodiment is attached, the amount of time and labor required for the building to be attached is reduced because the rails and side plates do not need to be attached along the wall facing the opening unlike the related art. It can be easily added to an existing building because it is less than a slide-swing type door device.

Furthermore, since the arm hinges 30A and 30B are both installed in an "offset-less" structure, the appearance of the entire door is further improved in combination with the installation of the decorative covers 17 and 18. That is, the upper arm hinge 30A almost appears integrally with the inner decorative bar 17 when the door is closed. Further, the lower arm hinge 30B is almost completely below the door panel 11 when the door is fully closed and fully opened. Is hidden. Thus, the support mechanism for opening and closing the door is almost inconspicuous.

Also, with this "offset-less" structure, the arm hinge supports the door panel 11 at the center or substantially the center position in the thickness direction of the door hinge, so that the arm hinge is orthogonal to the plate surface of the door panel 11. The force due to the twist in the direction, etc. is hardly applied to the arm hinge. Therefore, the durability of the arm hinge is improved, and the reliability of the door device in long-term use is also improved. Further, by adopting the "offset-less" structure, there is an advantage that the door device can be easily applied to a door in the opening direction of either the left or the right.

In addition to the various advantages described above, according to the slide-swing type door device of the present embodiment, a situation in which a finger or an object is pinched in a gap around the door panel 11 when the door is closed is prevented or reliably reduced. As a result, it is possible to provide a door device in which sufficient structural considerations are taken when the door is mounted or used thereafter.

Specifically, as schematically shown in FIG.
Since the distal end of the upper arm hinge 30A has a rounded portion 31a, a gap as viewed from an oblique direction of the upper inner decorative bar 17 in a door fully closed state or a closed state close to it is as follows.
It is larger than that of a conventional right-angled flat surface having no roundness (see the imaginary line N1 in the figure) (the gap as viewed from the direction of the opening is not changed). Therefore, particularly at the time of door installation and the like, the possibility that a finger or the like is caught in this portion is surely reduced.

As shown schematically in FIG. 11, the door panel 11 also has a rounded edge 11a at the hanging end thereof. In the case where the gap viewed from the oblique direction of the frame 12a is a conventional right-angled flat surface having no roundness (the virtual line N2 in the figure)
(See the gap when viewed from the entrance and exit directions). Therefore, when the door is closed, the possibility that a finger or an object is caught in this portion is reliably reduced.

Further, as can be seen from FIG.
The arm 30Ba of the lower arm hinge 30A has the shape of an offset arm, and is offset from the groove 16a of the guide rail 16. Therefore, the groove 16a does not intersect with the arm 30Ba while the door is being opened and closed. Therefore, there is no need to worry about a finger or an object being pinched between the groove 16a and the arm 30Ba.

In the above-described door apparatus, the structure in which the structure for preventing a finger or an object from being pinched is simultaneously applied to the upper arm hinge, the door panel, and the lower arm hinge has been described. However, the present invention is not necessarily limited to this. Instead, any one structure or only two structures may be implemented.

Modifications (Group 1) Various modifications of the slide-swing type door device according to the first embodiment will be described with reference to FIGS.

All the modifications according to the group 1 are carried out on the upper arm hinge 30A described above.
Any structure in this group can be incorporated into the door device of the first embodiment and implemented.

In the modification shown in FIG. 12, the tip end of the upper arm hinge 30A is constituted by a cushioning member 50. As the cushioning member 50, for example, a hollow rubber material is used. Since the cushioning member 50 is configured as a part of the arm 31, it is preferable that the shape thereof be adjusted to the size of the arm 31 and that the length of the arm be longer than at least one finger in the longitudinal direction of the arm. With this, even if a finger or an object is caught,
The shock is alleviated by the deformation of the buffer member 50.

In the modification shown in FIG. 13, a screen 51 for closing a gap between the tip of the upper arm hinge 30A and the inner decorative cover 17 is provided in order to prevent a finger or an object from entering. It is provided. This screen 5
As 1, a roll screen or an accordion curtain that expands and contracts according to a gap that changes as the door panel opens and closes is used. The winding portion of the screen 51 may be attached to the inside of the distal end of the arm 31 or to a part of the inner side surface of the inner decorative cover 17. This makes it possible to almost completely prevent a state in which a finger or an object itself enters the gap.

By utilizing the elasticity of the screen, a function of a soft closer for the door can be provided.

In the modification shown in FIG. 14, a part of the tip of the upper arm hinge 30A is detachable. In other words, the arms 31 of the arm hinge 30A have substantially the same cross-sectional shape, but the main arm 31M on the suspension side.
And a sub-arm 31S on the distal end side. The tip of the main arm 31M rotatably suspends the door panel, and the sub-arm 31S is separated from this suspending function. The main arm 31M and the sub arm 31S have a fitting structure 5 formed between them.
They are detachably connected to each other by 2 and usually move together to form an arm hinge. This fitting structure 5
2 indicates that the sub-arm 3
When it acts on 1S, such engagement is released by an action such as the engagement of the claw member being released, and the sub arm 31S is released. Therefore, even if a finger or an object is pinched, there is no fear that excessive force is applied to them.

The modification shown in FIG. 15 uses a hinge mechanism instead of the fitting mechanism shown in FIG. That is, the main arm 31M configured similarly to that of FIG.
And the sub arm 31S are connected by a hinge mechanism 53. The hinge mechanism 53 includes two arms 31M, 31
S is mounted on the indoor side of S. Normally, both arms 31M and 31S are moved as one arm 31, but when a stress equal to or more than a certain value is applied to the sub arm 31S, for example, a locking mechanism such as a nail coming off is used. Then, the connection of both arms is released. Even in this release state,
The sub arm 31S does not come off and the main arm 31M
Stop while connected to. For this reason, even if a finger or an object is caught in such a gap, there is no fear that the sub arm 31S will come off and excessive force will be applied to them.

The above-described mechanism for preventing a finger or the like from being pinched at the tip of the upper arm hinge 30A is provided at the tip of the inner decorative bar 17 adjacent to the arm hinge or at the arm adjacent to the upper frame 12b. May be implemented.

Modifications (Group 2) Various other modifications of the slide-swing type door device according to the first embodiment will be described with reference to FIGS.

All the modifications according to the group 2 are performed on the door panel 11 described above, and any structure in the group can be incorporated into the apparatus of the first embodiment.

First, in the modification shown in FIG. 16, a part of the hanging-side end of the door panel 11 is constituted by a buffer member 60. As the cushioning member 60, for example, a hollow rubber material is used. The cushioning member 60 is the door panel 1
Since it is configured as a part of the first panel, it is desirable that the shape such as its thickness is in accordance with the dimensions of the door panel 11 and that the panel has a length of at least one finger in the panel width direction. Thus, even if a finger or an object is caught between the side frame 12a and the door panel 11, the shock is reduced by the deformation of the cushioning member 60.

The modified embodiment shown in FIG.
In order to prevent a finger or an object itself from entering, a screen 61 for closing a gap between them is provided between the hanging-side end portion and the side frame 12a. As the screen 61, a roll screen or an accordion curtain that expands and contracts according to a gap that changes as the door panel opens and closes is used. The winding section 61a of the screen 61
It is attached to a groove 12aa formed in the side frame 12a along the vertical direction from the panel side. This makes it possible to almost completely prevent a state in which a finger or an object itself enters the gap.

By utilizing the elasticity of the screen, a function of a soft closer for the door can be provided.

The modified embodiment shown in FIG.
Are partially detachable along the vertical direction. That is, the door panel 11 has substantially the same cross-sectional shape, but has a folding door-like structure of a main panel 11M located on the turning side opposite to the hanging side and a sub-panel 11S at the tip of the hanging side. I have. In this case, the main panel 11M is rotatably suspended by the arm hinge 30A. Main panel 11M and sub panel 11S
Are connected by a hinge mechanism 62. This hinge mechanism 6
2 is mounted on the indoor side of both panels 11M and 11S. Normally, both panels 11M and 11S are moved as one door panel 11 (see FIG. 2B). Is applied, the connection of the two panels as a panel is released by a locking mechanism such as the removal of a nail (see FIG. 3A). Even in this release state, the sub panel 11S does not fall off and stops while being connected to the main panel 11M. For this reason, even if a finger or an object is caught in the gap between the side frame 12a and the sub-panel 11S, the sub-panel 11S does not come off, and there is no fear that excessive force is applied to them.

Modifications (Group 3) FIGS. 19 to 24 show various other modifications of the slide-swing type door device according to the first embodiment.
It will be described based on.

All the modifications according to the group 3 are carried out on the lower arm hinges of the door panel 11 described above, and any structure in this group can be incorporated into the device of the first embodiment. it can.

First, the lower arm hinge 71 according to the modification shown in FIG. 19 has an offset arm structure as described above, but the offset position is inverted at about a half position in the length direction of the arm. It is characterized by being. In other words, the arm 71a of the lower arm hinge 71 has an approximately half front half portion F extending from the base end attached to the rotating shaft 71b that is axially mounted on the floor, and is offset to one side, and
When reaching the rear half portion L, the rotating shaft 71c is offset to the opposite side and is directly mounted on the lower end surface of the door panel 11 as it is.
To the tip attached.

This offset arm structure is similar to the arm 71
Focusing on the fact that the probability that a finger or an object is caught between the rail and the rail groove 16a is high on the hanging side of the door panel, that is, on the base end side of the arm 71, only the base end side half thereof Function as an offset arm. That is, when the door is closed, the arm 71a and the rail groove 16a do not intersect with each other when the door is closed, so that the pinch does not occur, and the initial purpose of preventing the pinch by the lower arm hinge is prevented. Can be achieved satisfactorily.

By processing the arm 71a into an offset arm which is symmetrically offset on both sides along its length, the base end and the distal end of the arm 71a are reversed. Can also be used. Further, a rotating shaft 7 attached to both ends of the arm 17a
By processing the structures 1b and 71c to be the same (common), there is an advantage that even if the doors are opened and closed in the opposite directions, the directions of the arm hinges need only be reversed, and the doors can be commonly used. The opening / closing direction of the door naturally depends on the situation at the installation site. However, by configuring the lower arm hinge 71 in this way, even if the door opening / closing direction changes in the opposite direction, the common lower arm hinge is used. it can. As a result, the types of parts stock are reduced.

The lower arm hinge 72 shown in FIG.
It is configured with the same purpose as the nine hinges. The arm 72a of the hinge 72 has a substantially Z (S) shape. That is, the arm 72a is pivotally mounted on the floor 72b.
Offset once to one side from the base end attached to
From this position, it gradually shifts to the other side, and finally bends again to reach the tip end portion on which the rotating shaft 72c is attached to the lower end surface of the door panel 11 and attached. With this hinge structure, the same or equivalent effect as that of FIG. 19 can be obtained.

Second Embodiment Next, a second embodiment according to the present invention will be described with reference to FIG. In this embodiment, the same or equivalent components as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified.

The slide-swing type door device according to this embodiment is also characterized in that it has a protective measure against pinching of a finger or an object when the door is closed. However, this safeguard is
Different from the above-described embodiment and its modified embodiments, the door panel itself as a door body is detached from a predetermined door position when a finger or an object tries to get caught.

FIG. 21 schematically shows how the upper hinge arm 81 having the detachment mechanism is attached. The upper arm hinge 81 includes an elongated long plate arm 81a, and clamps 81b and 81c are formed at both ends. Among these, the base end side clamp portion 81b located on one side frame 12a side and the other end side clamp portion 81c are formed with a split opening along the arm longitudinal direction. The base-side clamp portion 81b is rotatably connected to a shaft 82 fixed to the side frame 12a, and the distal-side clamp portion 18c is rotated about a shaft 83 which is mounted on the upper end surface of the door panel 11. It is freely connected.

In addition, the clamp portions 81b and 81c
The slits formed on the door panel and / or the arm hinges 81 can be disengaged (separated) from the respective shafts 82 and 83 when a force (impact) of a predetermined value or more is applied to the door hinges 81. The size (size) and direction are set.

For this reason, when the door is normally opened and closed, the clamp portions 81b and 81c are rotatably connected to the shafts 82 and 83, respectively. Therefore, the door panel 11 can be rotated by the upper arm hinge 81, and a predetermined slide / swing operation is performed in cooperation with other elements such as a six-wheel slide roller.

However, when a finger or object is caught between the side frame 12a and the door panel 11 when the door is closed, the door panel 1
1, a force (impact) greater than a predetermined value is applied. This force is applied via the door panel 11 to the clamp portion 81c on the distal end side.
At the same time, via the arm 81a, the clamp portion 8 on the proximal end side.
1b. For this reason, the clamp portions 81b and 81c are separated from one or both of the rotation shafts 82 and 83 via the splits. Therefore, since the door panel 11 itself deviates from the predetermined opening / closing trajectory, a pressure greater than a predetermined value is not applied to a finger or an object, and damage can be avoided.

It is not always necessary to form the detachable split provided on the upper arm hinge 81 at both ends thereof, and a configuration in which the split is formed only at one end thereof is also possible.

Further, the above-described detachment structure is intended for detachment between the upper arm hinge 81 and the door panel 11.
In the case of the present invention, a similar detachment mechanism may be provided between the six-wheel slide roller and the door panel 11 additionally or independently. For example, as shown in FIG. 21, in a normal state, it is rotatably connected to a shaft 84 of a six-wheel slide roller,
Further, at the time of sandwiching, the clamp portion 85 which can be detached through the split may be fixed to the upper end surface of the door panel 11. By providing such a detachment mechanism on both the upper arm hinge and the six-wheel slide roller, the detachment function can be ensured.

Further, the detaching force set in the above-mentioned clamp portion can be adjusted by changing the strength of the clamping force and the direction of the split. One example of this is shown in FIGS. The arm hinge 86 shown in FIG. 9A is provided with the direction of the split in a direction orthogonal to the longitudinal direction of the arm. The arm hinge 87 in FIG. 7B obliques the direction of the split with respect to the longitudinal direction of the arm. Further, the arm hinge 88 in FIG. 3C is set so that the direction of the split is a direction orthogonal to the arm longitudinal direction, and is opposite to each other at both ends. An appropriate arm hinge can be selected according to the shape of the door and the detaching force.

Further, the detaching structure by the above-mentioned clamp portion is not limited to the one set on the upper end side of the door panel 11. As an example, as shown in FIG. 23, the present invention may be applied to a lower arm hinge. The lower arm hinge 89 shown in FIG. 9A has an offset arm structure in which the arm 89a is linearly offset, as described above, and has crank portions 89b and 89c at both ends.
The directions of the splits of the crank portions 89b and 89c are the same, and are set to be orthogonal to the arm longitudinal direction. The lower arm hinge 90 shown in FIG. 3B has an offset arm structure in which the arm 90a is linearly offset, and has a crank 90 at both ends.
b, 90c. The directions of the splits of the crank portions 90b and 90c are opposite to each other, and are set to be along the longitudinal direction of the arm. Further, the lower arm hinge 91 shown in FIG. 3C has an offset arm structure in which the arm 91a is linearly offset, and has crank portions 91b and 91c at both ends. The directions of the splits of the crank portions 91b and 91c are the same as each other, and are set in the direction orthogonal to the longitudinal direction of the arm and opposite to the offset side. By selecting the lower arm hinge having such an appropriate shape in accordance with the door shape and the setting force at the time of detachment, an accurate door panel detachment effect against the above-described pinching of a finger or an object can be obtained.

Third Embodiment A slide-swing type door device according to a third embodiment of the present invention will be described with reference to FIGS.

This door device is intended to prevent a finger or an object from being pinched by detaching a door panel as a door from a predetermined opening / closing track similarly to the purpose of the second embodiment described above. , Characterized by the structure of the detachment mechanism.

FIG. 24A is a plan view of the detachment mechanism 100, and FIG. 24B is a side view thereof. The release mechanism 100 is connected to a connection shaft between the upper arm hinge and the door panel, for example, as described in the embodiment, and / or
Alternatively, it is inserted as a traveling tool on a connecting shaft between the six-wheel slide roller and the door panel.

The detaching mechanism 100 includes a hanging bracket 101, a shaft 1
02, bearing material 103, spring 104, strength adjusting screw 105
And so on. The hanging metal fitting 101 is formed by folding a plate material so as to have an internal space of a predetermined thickness, and is formed in a plate shape of a predetermined thickness with an opening at the end of the folding. The bearing member 103 is inserted into the suspension fitting 102 from the opening side so as to be able to advance and retreat, and the spring 104 is attached between the bearing member 103 and the other side surface of the suspension fitting 102. I have.

A groove 101a is cut in the upper plate of the hanging fitting 101 from the above-mentioned opening side along the longitudinal direction. The width of the groove 101a matches the diameter of the shaft 102, and the cut length is set in accordance with the detachment function described later. The shaft 102 is provided upright on the bearing member 103, and extends upward through the groove 101a.
This shaft 102 actually corresponds to the upper arm hinge and the rotation axis of the six-wheel slide roller.

The upper plate of the hanging bracket 101 has the groove 1
An elongated slit 101b along the longitudinal direction is formed at the same width direction position as that of the slit 01a as shown in FIG. The slit 101b has the strength adjusting screw 105
Is loosely inserted, and this screw can be screwed into the bearing member 103. The bearing member 103 is constantly urged in the opening direction in the hanging bracket 101 through the spring 104. Therefore, the biasing force of the spring 104 can be adjusted by changing the tightening position of the screw 105 in the slit 101b.

Further, the bearing member 103 is urged by the spring 104 so as to be pushed out of the hanging member 101 in the opening direction thereof. During opening and closing, the shoulder is locked and fixed.

On the other hand, a shaft 106 attached to the upper end surface of the door panel is attached to the lower plate of the hanging bracket 101 at a position facing the shaft 102.

FIGS. 25 to 28 show an example in which the detaching mechanism 100 thus constructed is actually mounted. Figures 25 and 26
FIGS. 27 and 28 show a state in which the detachment mechanism 100 is mounted between the upper arm hinge 107 and the door panel 11.
3 shows a state in which it is attached between the six-wheel slide roller 108 and the door panel 11.

When the door is normally opened and closed, the bearing member 103 is locked by the claw member 101c. Therefore, as shown in FIG. 24, the release mechanism 100 is in a state shown by a solid line, and the door panel 11 is a normal door. Can perform slide operation and swing operation. However, when a finger or an object is caught in the door and a predetermined value of force (shock) is applied to the door panel 11,
The locking between the bearing member 103 and the claw member 101c is released due to the force. As a result, the bearing member 103 is
(See the underlined drawing in FIG. 24). As a result, the door panel 11 is displaced in the direction in which the force of the pinch escapes, so that a force of a certain value or more is not applied to a finger or an object, and injuries or damages thereof can be reliably avoided.
The strength of the force causing the detachment can be adjusted by the spring 105.

The detaching mechanism 100 is similar to that shown in FIG.
As shown in (b), when provided between the upper arm hinge and the door panel, as an example, the hanging bracket 101 is attached so that its longitudinal direction is orthogonal to the arm hinge, and
The front end of the hanging bracket 101 is attached so as to face the moving direction of the tip of the arm hinge when the door is closed. However, if the direction of the hanging metal fitting 101 changes, the force at the time of detachment changes, so that the hanging metal fitting 101 can be attached in an arbitrary direction and the force can be adjusted.

The detaching mechanism 100 is similar to that shown in FIG.
As shown in (b), when provided between the six-wheel slide roller and the door panel, as an example, the hanging metal fitting 101 is attached so that its longitudinal direction is orthogonal to the door panel, and the front end of the hanging metal fitting 101 has a door open. Sometimes attached to the hanging side. However, if the direction of the hanging metal fitting 101 changes, the force at the time of detachment changes, so that the hanging metal fitting 101 can be attached in an arbitrary direction and the force can be adjusted.

The detaching mechanism 100 may be provided on only one of the upper arm hinge and the six-wheel slide roller.

Fourth Embodiment A slide-swing type door device according to a fourth embodiment of the present invention will be described with reference to FIGS.

This door device is intended to prevent a finger or an object from being caught by detaching the door panel as a door body from a predetermined opening / closing trajectory, similarly to the gist of the second and third embodiments described above. And the feature of the structure of the detachment mechanism.

FIG. 29 is a perspective view showing the structure of the detachment mechanism 130, and FIG. 30 is a perspective view showing the state of attachment. The detachment mechanism 130 is provided on a connection shaft between the upper arm hinge and the door panel, for example, as described in the above-described embodiment, and / or on a connection shaft between the six-wheel slide roller and the door panel as a traveling tool. Insert.

The release mechanism 130 includes a shaft 131, a rectangular plate-shaped bearing plate 132, a gripping clamp 133, a wire spring 134, and the like, which are formed by an upper arm hinge and a shaft of a six-wheel slide roller. Prepare.

As shown in FIG. 30, the bearing plate 132 is made of a rectangular plate having a predetermined thickness and fixedly installed on the upper end surface of the door panel 11 with its height buried.

The latch 133 is formed in a grip-like shape as a whole, and is arranged on the upper surface of the bearing plate 132. More specifically, the locking member 133 includes two metal pieces 133a and 133b having a gripping structure, and these metal pieces 133 are provided.
The holes 133c individually formed at one end of the a and 133b are used as a common fixing hole. Bracket pieces 133a, 133b
Are fixed to the bearing plate 132 by screws 133d through the common holes 133c, and are rotatable around the screws 133d.

At the time of this fixing, the screw 133d is
It is screwed in such a manner that a spring 134 fixedly arranged on 3a, 133b is sandwiched therebetween. That is, the spring 134 orbits around the common hole 133c, and the orbital portion is the screw 133.
d, and both ends of the metal piece 13
3a, 133b, the two metal pieces 133
a, 133b, their ends (open ends) are individually fixed. For this reason, the two metal pieces 1
An urging force always acts on the outer surfaces of the brackets 33a and 133b, that is, in the direction in which the metal pieces are to be opened.

On the bearing plate 132, the claw members 132a, 13
2a is fixed. The claw members 132a, 132a
Are metal pieces 133a, 133 located on the bearing plate 132.
The two metal pieces are locked so that the opening of b by the spring 134 is not permitted except under predetermined conditions. Therefore, in the normal door opening / closing state, the urging force of the spring 134 and the locking force of the claw members 132a, 132a are balanced. However, the spring 134 and the claw members 132a, 132a
When a force (impact force) greater than a predetermined value when a finger or object is sandwiched in the gap created by the door panel is applied between them, the spring constant and claw The strength (height, position, etc. of the nail) is set in advance.

Further, at a predetermined position opposite to the common hole 133c of both the metal pieces 133a and 133b, and at the center position in the width direction thereof, each metal piece is cut out in a substantially semicircular shape. A circular through hole 133e is formed by both. The shaft 131 passes through the through hole 133e, and a part of the shaft 131 is inserted into a hole 132b provided in the bearing plate 132. Both bracket pieces 133a, 133b of shaft 131
A concave step 131a is formed at a position where the step 131a comes into contact with. At the time of normal door opening and closing, both bracket pieces 133a, 13
The diameter of the through hole 133e formed by the joint 3b is
It is set smaller than the outer diameter of 1a. Therefore, FIG.
As shown in the figure, the step 131a is locked in the through hole 133e, and the shaft 131 is fixed to the bearing plate 132 (that is, the door panel 1).
It is integrally and rotatably connected to 1).

FIG. 31 shows an example in which the above-described detachment mechanism 130 is provided at a position where the upper arm hinge 135 and the door panel 11 are pivotally attached. In this case, for example, the direction of the open end of the locking metal fitting of the detachment mechanism is set so as to face the doortip (rotation) direction. FIG. 32 shows an example in which the above-described detachment mechanism 130 is provided at a position where the six-wheel slide roller 136 and the door panel 11 are axially attached. In this case, the direction of the open end of the latch of the release mechanism is, for example, a door end (hanging source).
Attached to face. 31 and 32 may be installed in opposite directions.

For this reason, when the door is normally opened and closed, the locking member 133 is locked by the claw members 132a and 132a of the bearing plate 132, so that the door panel 11 can perform a normal sliding operation and a swing operation. However, when a finger or an object is caught in the door, a predetermined value of force (shock) is applied to the door panel 1.
At the time when it is added to 1, the locking metal 133 is released from the locking of the claw members 132a, 132a due to the force. As a result, the metal pieces 133a and 133b of the locking metal 133 are immediately opened by the spring force of the spring 134, so that the shaft 131
The shaft attachment between the shaft and the bearing plate 132 is also released instantaneously. As a result, the door panel 11 is detached from the upper arm hinge and the six-wheel slide roller, and the door panel 11 is shifted from the proper door position. Therefore, a force equal to or greater than a certain value is not applied to a finger or an object, and injury or damage to the finger or object can be reliably avoided.

The detaching mechanism 130 may be provided on only one of the upper arm hinge and the six-wheel slide roller.

The shaft 70 is connected to shafts 171a and 171b which are supported through the shaft 70. Of the shafts, the lower shaft 171a serves as a rotation axis of the pinion 173, and the upper shaft 171b is detachably connected to a shaft 154 passing through the door panel 11.

The pinion 173 meshes with the rack 152a and is movable along its longitudinal direction. In addition, the two rollers 172 have a shaft body 171b extending upward.
And a groove 15 of the lower guide rail 152.
They are juxtaposed along the longitudinal direction so as to slide or roll on the side surface of 2 m. Therefore, the rotation of the pinion 173 is transmitted to the shaft 154 of the door panel 11 via the transmission gear mechanism 171.

A pair of upper and lower running tools 1 configured as described above
As shown in FIG. 41, 55 and 156 are distances D of 1/3 to 1/2 from the handle side with respect to the width WD of the door panel 11.
It is desirable to install in In this embodiment, the traveling tools 155 and 156 are set at a distance of 1/3 from the handle side by selecting shafts attached at a plurality of positions.

Therefore, the door panel 11 is connected to the shaft 15
When the rotation is made about the center axis 4, the rotation is transmitted to the upper and lower pinions 163 and 173 at a variable speed. The upper and lower pinions 163 and 173 are respectively upper and lower racks 151a,
The upper and lower guide rails 1 rotate while meshing with the
51 and 152 move in the longitudinal direction. At this time, since the upper and lower running tools 155 and 156 move synchronously in position, the door panel 11 rotates (swings) around the vertical shaft 154 as shown in FIG. Move laterally along 152. This allows the door panel 11 to smoothly open and close.

As described above, according to the slide-swing type door device of the present embodiment, the shaft penetrating vertically through the door panel is fixedly installed at an arbitrary position in the width direction of the door panel.
A rotatable and travelable traveling tool was attached to each of the upper and lower ends of the shaft, and the upper and lower traveling tools were movably accommodated in upper and lower guide rails. The upper and lower guide rails are installed inside an upper frame and a floor (lower frame) attached along an upper edge or a lower edge of the opening. The upper and lower guide rails are provided with a rack extending from one end to the other end in the width direction of the opening, and continuous with the longitudinal direction thereof. Go to A speed change gear mechanism for linking rotation of the pinion and rotation of the shaft of the door panel is installed in the upper and lower traveling tools. Thus, in the opening / closing operation, the rotation and the lateral movement of the door panel are linked with each other, the movement path of the door panel is uniquely determined, and the door panel slides and swings to open and close.

For this reason, for example, Japanese Patent Application Laid-Open No.
It has various advantages as compared with the door devices described in JP-A-4,067 and JP-A-54-112536.

First, at the time of opening / closing operation, the body can be easily opened / closed without moving and operating the body, which is excellent in usability. Also, since the door body has a small amount of opening, can be opened and closed in a small space, and does not obstruct traffic, it is possible to provide a door device that is easy to use for all persons such as healthy persons, elderly persons, persons with disabilities, and wheelchair users. . In addition, there are few restrictions on the installation location, the construction is simple, and the appearance is not impaired. That is, it can be installed even in a place where there is no side wall on any of the left and right sides of the opening, and there is no member to be attached and constructed outside the door frame, so holes are formed in the wall and floor outside the door frame, Construction work such as embedding is unnecessary. Since only the door frame needs to be attached to the opening, installation work is easy, and there is no need for an outgoing support post or an arm (rotating rod) for hanging the door, and the appearance is improved.

[0127] Further, since the door is laterally moved by a pair of synchronously-moving traveling tools located above and below the door (door panel), the rotation axis of the door is always maintained vertically. For this reason, there is almost no situation where the door body tilts in the front-rear and left-right directions or rattles during opening / closing, and a reliable opening / closing operation can be obtained with smooth and stable movement.

Further, since the mounting position of the upper and lower running tools can be changed by changing the selected position of the shaft, the movement path (opening / closing path) of the door body can be freely adjusted by adjusting the mounting position. In other words, the user likes or
Since the moving path of the door body that can be easily opened and closed can be selected, it is easy to avoid interference with other doors so as not to hinder walking in a room or a passage or an installed object.

Further, since the running tool and the shaft, that is, the door body are detachably connected, the door body can be removed even when an emergency such as a person having a seizure occurs in the toilet room. Can be quickly removed from the outside of the room, and such an emergency can be dealt with.

Further, since the door body has a structure capable of being fully moved laterally from one end to the other end of the door frame, by arranging the shaft at the center thereof, a symmetric opening and closing operation can be performed. That is, it can be used for both right-opening and left-opening. Also, it can be easily applied to an irregular opening as shown in FIG.

Further, in the opening / closing operation from the indoor side and the outdoor side, the relative opening / closing path of the door body as viewed from the user becomes the same, so that the user always has the same opening / closing operation toward the door body. . Also, in the operation of opening the door body,
The direction in which the door body opens changes between the case where the door knob is moved straight forward or forward and the case where the door body is opened while moving the door knob in the horizontal direction, so that the door body can be used for both right and left opening.

Although the gear ratio of the transmission gear mechanism may be set arbitrarily, a preferred example is as shown in FIG.
That is, as the rotation angle θ of the shaft 154 from the door closed state, the lateral movement distance L of the shaft 154, and the thickness d of the door panel 11,

## EQU1 ## The gear ratio is set so that L = 2 (D−d / 2) θ / π. Thus, an open state in which the door panel 11 is maximally opened when rotated by 90 degrees is obtained.

Further, since the mounting position of the traveling tool is variable as described above, the moving path of the door panel can be freely adjusted to some extent by changing the mounting position. For this reason, the user can select a door movement path that is easy for the user to open and close, and adjust the door appropriately so as not to hinder walking or installation in a room or a passage, or to avoid interference with other doors. It is possible to provide an easy-to-use door device.

Further, in this embodiment, the mounting position of the traveling tool is of a variable selection type. However, only one shaft may be used and provided at a predetermined position, and the traveling tool may be fixedly mounted. .

Further, in this embodiment, the rack is provided inside the upper and lower guide rails, but the guide rail and the rack may be separated.

Further, a lower frame is provided instead of the structure in which the lower guide rail and the lower rack are buried on the floor at the lower edge of the opening.
A lower guide rail and a lower rack may be additionally provided in the lower frame.

In other words, the relative door opening / closing path as viewed from the user is the same between the opening / closing operation from the indoor side and the opening / closing operation from the outdoor side. The user can always open and close the door by the same opening and closing operation with respect to the door panel 11 (for example, in the case where the door is opened by operating in the direction of arrow A in FIG. 46, the door is also opened in the direction of arrow A in FIG. 47). . Further, since the door panel 11 moves from one end to the other end of the door frame and moves symmetrically, the door panel 11 can be used for both right-opening and left-opening.

In this modification as well, the position at which the pair of upper and lower traveling tools is installed is not necessarily limited to the center position in the width direction of the door panel 11, but may be any position between one end of the door panel 11 and the other end. Position.
