Description

The present invention relates to a door having a latch mechanism.

In a general latch mechanism provided on the door end side of a hinged door, the latch bolt is urged by a spring in a protruding direction (Patent Documents 1, 2, etc.). In the closed position of the door, the latch bolt protrudes and engages with the latch receiver of the door frame to fix the door in the closed position.
When opening a door in a closed position, the latch bolt must be temporarily retracted against the spring, and the handles such as the lever handle and push-pull handle that operate it are integrated with the latch and the door. It is designed as a separate part from the main body.

Assuming that the latch is released by various parts of a human being having various physical characteristics, it is preferable that there is a degree of freedom in the position of the part to be operated for the latch release.

Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples. In the drawings, the same or similar components in each embodiment are basically the same reference numerals. In addition, the same or similar components already described in another embodiment may be omitted.

The door to which the present invention is applied is a single door that opens and closes by rotating around a vertical rotation shaft at one end. Regarding the width direction of the door body, the rotation axis is referred to as "door tail side", and the side opposite to the rotation axis is referred to as "door tip side". The direction of rotation when opening and closing the door changes depending on how the hinge is installed, but for convenience, the doors A to G when the hinge is installed as shown in FIGS. 1, 4, 5, 6, 7, 8 and 9. One door surface is the front door surface 30a, and the other door surface is the back surface of the door 30b.

(1) First Embodiment With reference to FIGS. 1 and 3, the configuration of the door A of the first embodiment of the present invention will be described. FIG. 1 is a schematic perspective view of the door A of the first embodiment as viewed from diagonally above. FIG. 3 is a diagram schematically showing an I-I cross section of FIG. The door A of the first embodiment is a door that can be opened only on one side of both door surfaces. In FIG. 1, as an example, it is assumed that one wing of the hinge is fixed to the wall on the door butt side of the door A and the other wing is fixed to the door butt side of the door. A door that can be opened with the hinge core rod as the central axis is shown in the door opening direction P shown by the curve of.

The door A of FIG. 1 includes a door body 1a and a door case 2a as large-sized components. The door case 2a is formed so that a part of the door body 1a can be stored.
The door body 1a is connected to the door case 2a by a rotation shaft 4a so that the door body 1a can rotate with respect to the door case 2a. Since the door case 2a is connected to the hinge 6, it is the door body 1a that rotates about the rotation shaft 4a. There are various methods for providing the rotating shaft 4a to realize this rotating movement. For example, a hole is provided through the door case 2a from the door front 30a side, through the door body 1a, and to the door back surface 30b side of the door case 2a, through which a shaft fixed to the door body 1a is passed, and this shaft is passed. And the door case 2a may be in contact with each other via a bearing. In order to realize the rotation of the door body 1a with respect to the door case 2a, a hole penetrating the door case 2a or the door body 1a is not always required.

An elastic body 5a is installed so as to be arranged in the door case 2a and to urge the door body 1a to the door end side of the door A.
As a method of fixing the elastic body 5a in the door case 2a or fixing the elastic body 5a to the door body 1a side, it is conceivable to install the elastic body 5a via a support member.
As shown in FIG. 1, the state of the door A when the door A is in the closed position and the latch 3a is housed in the latch receiver is defined as the closed state position. The role of the elastic body 5a is to urge the door body 1a to return to the closed position from the door A state in which the latch is released by rotating the door case 2a around the rotation shaft 4a. That is, the state of the door body 1a with respect to the door case 2a when the door case 2a is in the closed state is maintained even when the force for rotation is not applied.
An elastic body 5a having a characteristic capable of fulfilling this role will be installed, and there is no restriction on the number of the elastic bodies 5a to be installed as long as the elastic body 5a can fulfill the role. For example, like the elastic body 5a shown by the broken line in FIGS. 1 and 3, it can be installed at a place inside the door case in the direction of the door tail of the door A. In this case, there is a restriction that the rotating body 4a must be below the height of the central axis. As another portion, it is also possible to install the elastic body 5a on the lower bottom surface in the door case 2a. In this case, there is a restriction that the door must be on the door end side of the central axis of the rotation shaft 4a and on the door end side of the opening surface of the door case 2a.

There is a latch portion 3a as a portion that fulfills the latch function, but it is formed so that at least a part of the side surface of the door body 1a on the door end side protrudes, and has a structure integrated with the door body 1a.
In the closed position of the door A, the latch portion 3a is accommodated in the latch receiver to perform the latch function.
The shape and the like of the latch portion 3a are restricted by the location and shape of the latch receiver, but there are no main restrictions on the arrangement and shape of the latch portion 3a except for the restrictions due to the surrounding environment.
In order to strictly prevent the door A from being opened in the door opening direction P indicated by the curve of the arrow in FIG. 1, the door front 30a side of the latch portion 3a is in a plane perpendicular to the door A opening direction. As shown in, it is preferably a flat surface.
In order to allow the latch portion 3a to be accommodated in the latch receiver without requiring a specific operation using the operation portion 7a when the door A is changed from the open state to the closed state, the back surface of the door of the latch portion 3a is used. As shown in FIG. 1, it is preferable that the surface on the 30b side has a curved surface that is fan-shaped in the cross section.
Further, in the rotated state of the door body 1a in which the latch can be released, the latch portion is parallel so that the line on the door end side of the latch portion 3a and the line on the door side of the latch receiver are parallel when viewed from the front. It is desirable that 3a is formed. This makes it possible to prevent the latch portion 3a from deteriorating over time due to strong contact of the latch receiver with only a part of the latch portion 3a.

The operation unit 7a is provided on both sides of the door front surface 30a and the door back surface 30b of the door body 1a.
In the first embodiment, in order to change the door A from the closed state to the open state by operating the operation unit 7a, a downward force is applied to the operation unit 7a, and the door body 1a is moved by the rotation shaft 4a. By making the operation rotate around, the latch portion 3a is released from the latch receiver, and then a force is applied to the operation portion 7a in the opening direction P of the door. The same operation is performed for any of the operation units on both sides of the door surface of the door body 1a.
In order to change from the open state to the closed state by operating the operation unit 7a, basically, the door body 1a or the operation unit 3a may be simply pushed forward without performing the operation in the reverse procedure.
The shape of the operation unit 7a may be any shape as long as the above operation can be performed, and there are no main restrictions. If a simple rectangular parallelepiped structure is used as shown in FIG. 1, a material that easily causes friction is provided on the upper part so that a force in the door opening direction P can be easily applied to the operation unit 7a, or a member that easily causes friction is provided. It is preferable to use the operation unit 7a to provide the operation unit 7a.
The positions of the door main body 1a on the door front side 30a side and the door back surface 30b side need to be at least on the door tip side of the vertical straight line passing through the rotation shaft 4a. Further, in the rotation operation, it is necessary to provide the operation unit 7a at a position where the operation unit 7a does not come into contact with the door case 2a. Considering that the force for rotation is minimized, it is preferable that there is a distance from the center of the rotation shaft 4a.

In FIG. 1, since one wing of the hinge 6 is attached to the door case 2a and the other wing is attached to a wall or the like, the door A opens and closes around the core rod of the hinge 6.
The door case 2a includes a housing in which the side surface on the door end side is open, and has a structure in which the door body 1a is at least partially stored in the housing.
Since the door body 1a has a structure that can rotate in the door case 2a, the latch portion 3a can be released from the latch receiver or can be housed in the latch receiver.
An elastic body 5a is provided in the door case 2a, and the urging of the door body 1a toward the door end causes the door body 1a to rotate in the direction in which the latch portion 3a is housed in the latch receiver. , It is done without manual operation.
There are no major restrictions on the shape that the door case 2a can take, as long as the rotational operation of the door body 1a is possible within the door case 2a.
On the other hand, there are restrictions on whether the hinge 6 and the elastic body 5a can be attached, when the shape of the door body 1a is designed first, and other restrictions due to the surrounding environment.

In FIG. 1 showing the first embodiment, a part of the door body 1a is housed in the door case 2a. The door body 1a rotates about the rotation shaft 4a with respect to the door case 2a, so that the latch portion 3a is released from the latch receiver. The possible shape of the door body is restricted by its movement and the shape taken by the door case 2a.
FIG. 3 is a diagram schematically showing an I-I cross section of FIG. 1, but in FIG. 3A, an embodiment in which the door 1a has a rectangular door surface is shown. In this case, after the door body 1a rotates around the rotation shaft 4a to release the latch, the upper right and lower right of the door body 1a are the wall W side where the latch receiver is present and the door case 2a or the floor surface, respectively. This is an example in which a gap is provided between the wall W on the right side of the door body 1a and the floor surface or the door case 2a on the lower side of the door body 1a so as not to come into contact with each other.
FIG. 3B shows an example in which the door body 1a has an irregular shape so as not to come into contact with other surfaces when the door body 1a rotates as described above. .. FIG. 3C is a schematic view showing only the shape of the door body 1a. In this embodiment, the upper and lower side surfaces of the right side surface of the door body, which may come into contact with other surfaces when rotated, are inclined.
In addition to these shapes, the shape that the door body 1a can take is that if the door case 2a is egg-shaped as described above, the door body can be made egg-shaped accordingly.
The shape that the door body can take is mainly limited in terms of whether the rotating shaft 4a and the elastic body 5a can be installed, the shape of the latch portion 3a and the operating portion to be installed, and the like, but other than that. There are no restrictions.

(2) Second Embodiment The door B of the second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic front view of the door B of the second embodiment as viewed from the front.
In the second embodiment, as shown in FIG. 2, the door case 2b is shaped so as to house the entire door body 1b. Even in this case, by operating the operation unit 7b, the door body 1b rotates around the rotation shaft 4b, so that the latch portion 3b is released from the concave latch receiver existing on the wall W. It is essentially the same as the first embodiment.

Since the entire door body 1b is housed in the door case 2b, the operation unit 7b provided on the door body 1b must be accessible from the outside of the door case 2b. As shown in FIG. 2, a hole 9 for that purpose is opened in the door case 2b. The size of the hole 9 must be determined so that the operation unit 7b does not come into contact with at least the frame of the hole 9 when the operation unit 7b is operated to perform the rotation necessary for releasing the latch portion 3b from the latch receiver. Must be.

In the second embodiment, the side surface of the door case 2b on the door end side is open to the extent necessary for storing the door body 1b and rotating the door body 1b.
On the other hand, in the second embodiment, as can be seen from FIG. 2, at least the latch portion 3b formed on the door body 1b projects outward and is stored in the concave latch receiver existing on the wall side. Just do it.
In this respect, it can be said that there are less restrictions than the first embodiment.

(3) Third Embodiment The door C of the third embodiment of the present invention will be described with reference to FIG. FIG. 4 is a schematic perspective view of the door C of the third embodiment as viewed from diagonally above.
Compared with the first embodiment, the door case 2c is longer in the horizontal length of the door surface, and the door body 1c is shorter in the horizontal length of the door surface.
In the third embodiment, it is shown that the door body 1c can be shortened in the horizontal length. It is required that the operation unit 7c is not stored in the door case 2c and that the rotation shaft 4c is installed in the portion where the door body 1c is stored in the door case 2c.
In order to satisfy the horizontal length required for the door C, the horizontal length of the door case is increased by the shorter the horizontal length of the door body 1c. Then, when the elastic body 5c is provided on the door end side of the door case 2c, the length of the elastic body 5c needs to be corresponding to that amount.

In the first, second, and third embodiments, the operation units 7a, 7b, and 7c are operated so that the door bodies 1a, 1b, and 1c rotate around the rotation shafts 4a, 4b, and 4c. There is essentially no difference in that the latch portions 3a, 3b, and 3c have a mechanism for being released from the concave latch receiver existing on the wall W. The need for doors is about the size of the door cases 2a, 2b and 2c, the door bodies 1a, 1b and 1c, and how much the door bodies 1a, 1b and 1c are stored in the door cases 2a, 2b and 2c. Through these embodiments, it is shown that the door surface can be designed with a certain degree of freedom if the length in the horizontal direction of the door surface can be secured.

(4) Fourth Embodiment The door D of the fourth embodiment of the present invention will be described with reference to FIG. FIG. 5A is a schematic perspective view of the door D of the fourth embodiment as viewed from diagonally above. FIG. 5B is a schematic perspective view of the periphery of the rotating body 12 as viewed from diagonally above.
The door D of the fourth embodiment is a door that can be opened only on one side of the door surfaces on both sides. In this respect, it is common with the first to third embodiments. In FIG. 5, as an example, assuming an implementation example in which one wing of the hinge 6 is fixed to the wall on the door butt side of the door D and the other wing is fixed to the door butt side of the door D, the curve of the arrow is assumed. In the direction P of, a door that can be opened with the core rod of the hinge 6 on the central axis is shown.

The main common points with the first to third embodiments are that the door can be opened and closed by a hinge, the latch mechanism is integrated with the door, and the latch is released by a rotating operation. That is.

The main difference from the first to third embodiments is that the door case is not provided in the fourth embodiment, and the functions realized in the door case in the first to third embodiments are the first. In the fourth embodiment, it is realized in the space of the notch portion.

The door D according to the fourth embodiment has a notch portion 13 in which a part of the side surface of the door body 1d on the door end side is cut out from the door end side toward the door end side. .. This is a space for providing the rotating body 12 to which the latch portion is attached. The latch portion 3d is released from the latch receiver by rotating the rotating body 12 toward the door tail. A cutout portion 13 may be provided at any portion of the door body 1d on the door end side as long as the space can be fulfilled by the rotating body 12. FIG. 5 shows an example in which a notch is provided at the lower end of the door body 1d on the door end side. When the notch is provided below the door as shown in FIG. 5, it is assumed that the door D is opened and closed by the operation of the foot.
As with the installation site, the shape of the notch is not limited to the main shape as long as the rotating body 12 can perform its function. FIG. 5 shows an example in which a notch is formed so as to form a space of a triangular prism which is a right triangle on the door surface side.

The rotating body 12 and the door body 1d are connected via a rotating shaft 11 so that the rotating body 12 can rotate with respect to the door body 1d. The latch portion 3d is released from the latch receiver by rotating the rotating body 12 with respect to the door body 1d about the rotating shaft 11.
The door body 1d and the rotating body 12 are not directly connected, but are connected via the rotating shaft 11. There are various methods for providing the rotating shaft 11. For example, a method in which one wing of the hinge is provided on the door body 1d and the other wing is provided on the rotating shaft 11, or a method in which the rotating shaft 11 is provided on the main body and the rotating shaft 11 and the rotating body 12 are coupled to each other. And so on.

The rotating body 12 is provided with a latch portion 3d, an operating portion 7d, and an elastic body 5d.
When the rotating body 12 rotates, the latch portion 3d provided therein is released from the latch receiver. The force of the elastic body 5d can maintain the position in which the latch portion 3d is accommodated in the latch receiver. For these reasons, the rotating body must be considered as a set with the latch portion and must have a size capable of fulfilling its function.
The rotational movement of the rotating body 12 must be completed within the space of the notch portion 13. If it does not fit in the space, for example, when the notch 13 is provided at the lower end of the door body 1d as shown in FIG. 5, the rotating body 12 comes into contact with the floor surface in the rotating operation of the rotating body 12. Therefore, it may not be possible to rotate and the latch may not be released. On the contrary, if the rotational movement of the rotating body 12 is completed in the space of the notch portion 13 and the latch portion 3d provided on the rotating body 12 can perform the latch function, the main restriction on the shape of the rotating body is. do not have.

An elastic body 5d is provided which is arranged between the door body 1d facing the cutout portion 13 and the rotating body 12 and urges the rotating body 12 toward the door end side. One role of the elastic body is to maintain the state in which the latch portion 3d is housed in the latch receiver when the door D is in the closed state position.
One of the other roles of the elastic body is that the door D is in the open state and the latch portion 3d is released from the latch receiver, and the door D is in the closed state and the latch portion 3d is housed in the latch receiver. At the time of transition to the state, it is not necessary to apply a force in the direction of the door to the operating portion 7d, the elastic body 5d is compressed, and the latch portion 3d can be accommodated in the latch receiver. In order for the latch portion 3d to be smoothly accommodated in the latch receiver without applying a manual operation force against the elastic body 5d, the latch portion 3d comes into contact with the door frame in front of the latch receiver at the time of transition to the closed state. The surface of the latch portion 3d on the back surface 30b side of the door has a smooth curved surface. The latch portion 3d shown in FIG. 5 has one possible shape. The other components forming the door F are the same as those in the sixth embodiment described later.
As a method of fixing the elastic body, it is conceivable to provide each of the door body and the rotating body via a support member.

The operation unit 7d is provided to apply a force against the elastic body 5d to cause the rotating body 12 to rotate toward the door tail side.
As shown in FIG. 5, when the notch portion 13 is located below the door, it is assumed that the operation portion is operated by the foot. In this case, in order to pull the door D in the door opening direction P, it is necessary to transmit a force to the door D in the opening direction, and when the operation unit 7d is operated, the foot moves to the door opening direction P. Some kind of structure that does not shift is required. Generally, it is to make a catch as the operation unit 7d of FIG. 5 has.
Further, when the operation unit 7d is viewed from the door end side, if the upper side of the operation unit 7d has a curved shape as shown in FIG. 5, it is difficult to step on the operation unit 7d from above with a foot. It is possible to avoid aged deterioration of the operation unit 7d due to the above.

Since the latch portion is provided on the door end side of the rotating body 12, the degree of freedom in place is limited. However, it can be said that the degree of freedom in the installation location of the latch portion is sufficiently secured in that there is a degree of freedom in the location and shape of the notch portion 13 and the rotating body.

Consider the shape from another point of view. When the door 1d is viewed from the door surface side, the larger the area of the rotating body 12 on the door surface side, the higher the shielding function of the door, and the smaller the area, the lower the shielding function. If the area is increased due to the shielding function, the rotational operation of the rotating body 12 may not be completed in the space of the notch portion 13. If the shielding function is considered, it is also conceivable to separately provide a box-shaped case that does not interfere with the rotating operation of the rotating body 12 and can cover the notch portion 13 by attaching to the door body 1d. Will be.

In the first to third embodiments, the door case is provided with an elastic body so as to enable the rotation operation of the door body so that the latch portion integrated with the door body is released from the latch receiver. It played a role in realizing a mechanism that can return the state of the door body that has been unlatched to the state of the original door body that does not apply force to the operation unit without manual operation.
In the fourth embodiment, the role is realized by providing the rotating body 12, the rotating shaft 11, and the elastic body 5d in the space of the notch portion 13, and therefore the door in the fourth embodiment. D has a configuration that does not have a door case.
Even so, it is not essentially different from the first to third embodiments in that the door body is provided with a latch function and the latch is released by the rotational operation.

(5) Fifth Embodiment The door E of the fifth embodiment of the present invention will be described with reference to FIG. FIG. 6 is a schematic perspective view seen from diagonally above the door E of the fifth embodiment.
The door E of the fifth embodiment is a door that can be opened only on one side of the door surfaces on both sides. This point is common to the first to fourth embodiments. In FIG. 6, as an example, assuming an implementation example in which one wing of the hinge 6 is fixed to the wall on the door butt side of the door E and the other wing is fixed to the door butt side of the door E, the curve of the arrow is assumed. In the direction P of, a door that can be opened with the core rod of the hinge 6 on the central axis is shown.

The door E is different from the doors of the first to fourth embodiments in the mechanism for releasing the latch portion 3d.
In the first to third embodiments, the operation units 7a, 7b, and 7c are operated to rotate the door bodies 1a, 1b, and 1c with respect to the door cases 2a, 2b, and 2c, so that the latch portions 3a, 3b, 3c is released from the latch receiver, and in the fourth embodiment, the latch portion 3d is released from the latch receiver by operating the operation portion 7d to rotate the rotating body about the door body. Assuming that the door type of the first to fourth embodiments is an axial rotation type, the door E of the fifth embodiment receives the latch portion 3e by operating the operation portion 7e and sliding the door body 1e. It can be said that it is a slide type because it is released from.

There is a latch portion 3e as a portion that fulfills the latch function, but it is formed so that at least a part of the side surface of the door body 1e on the door end side protrudes, and has a structure integrated with the door body 1e.
At the closed position of the door E, the latch portion 3e is housed in the latch receiver to perform the latch function.
The shape and the like of the latch portion 3e are restricted by the location and shape of the latch receiver, but there are no main restrictions on the arrangement and shape of the latch portion 3e except for the restrictions due to the surrounding environment.
In order to strictly prevent the door E from being opened in the door opening direction P indicated by the curve of the arrow in FIG. 6, the side of the latch portion 3e on the front surface 30a of the door is formed on a plane orthogonal to the door opening direction P of the door E. As shown in FIG. 6, it is preferably a flat surface.
In order to allow the latch portion 3e to be accommodated in the latch receiver without requiring a specific operation using the operation portion 7e when the door E is changed from the open state to the closed state, the latch portion 3e is shown in the figure. Similar to the latch portion 3c of 4, it is preferably a fan-shaped pillar.

The operation unit 7e is provided on both sides of the door body 1e.
In the fifth embodiment, in order to change the door E from the closed state to the open state by operating the operation unit 7e, a force is applied to the door tail side in the horizontal direction of the door surface with respect to the operation unit 7d, and the door body is main body. By sliding 1e in that direction, the latch portion 3e is released from the latch receiver, and then a force is applied to the operation portion in the door opening direction P. This operation is performed on any of the operation units 7d provided on both sides of the door surface of the door body 1e.
As shown in FIG. 6, when the latch portion 3e takes the shape of a rectangular parallelepiped, in order to change from the open state to the closed state by operating the operation portion 7e, the movement of the reverse procedure is given to the door E. , The latch portion 3e is stored in the latch receiver. Similar to the latch portion 3c in FIG. 4, when the latch portion 3e is a fan-shaped pillar, in order to change from the open state to the closed state by operating the operation portion 7e, it is only necessary to push it toward the back surface 30b of the door. ..
The shape of the operation unit 7e may be any shape as long as the above operation can be performed, and there are no main restrictions. If a simple rectangular parallelepiped structure is used as shown in FIG. 6, a material that easily causes friction is provided on the side surfaces of the door end side and the door end side so that a force in the door opening direction P can be easily applied to the operation unit 7e. Alternatively, it is preferable to provide the operation unit 7e using a member that easily causes friction.
By applying a force via the operation portion 7e in the direction of contracting the elastic body 5e against the force of the elastic body 5e and sliding the door body 1e, the latch portion 3e is released from the latch receiver. It is necessary to provide the operation unit 7e so as not to come into contact with the door case 2e when sliding a distance sufficient to release the latch. There are no other major restrictions on the location of the operating unit.
If you want to minimize the force required to slide the door body 1e, the resultant force of the repulsive force of one or more elastic bodies 5e and the static friction force generated on the ground surface of the door body 1e and its lower surface. On the other hand, it is desired that the operation unit 7e is provided at a position where the force is applied in the opposite direction.

An elastic body 5e is installed so as to be arranged in the door case 2e and to urge the door body 1e to the door end side of the door E.
As a method of fixing the elastic body 5e with the door case 2e or fixing the elastic body 5e with the door body 1e, it is conceivable to install the elastic body 5e via a support member.
FIG. 6 shows a state in which the door E is in the closed position, and in this state, the latch portion 3e is housed in the latch receiver. This state is defined as the closed state position. The role of the elastic body 5e is to close the door body 1e in the direction in which the door body 1e is further stored in the door case 2e, that is, from the state of the door E in which the latch portion 3e is released from the latch receiver by sliding toward the door tail side. It is to urge and return to the state position.
Elastic bodies having characteristics and sizes capable of fulfilling this role will be installed, and there are no restrictions on the number of elastic bodies to be installed as long as they can fulfill that role. For example, like the elastic body 5e shown by the broken line in FIG. 6, it can be installed at a place inside the door case 2e in the direction of the door tail of the door E.

In FIG. 6, since one wing of the hinge 6 is attached to the door case 2e and the other wing is attached to a wall or the like, the door E opens and closes around the core rod of the hinge 6.
The door case 2e includes a housing in which the side surface on the door end side is open, and has a structure in which the door body 1e is at least partially stored in the housing.
The hinge 6 and elastic body 5e can be attached, the shape of the door body 1e is designed first, and there are certain restrictions due to the surrounding environment, but there are no other major restrictions on the shape. ..
Therefore, the door case 2e is not limited to a rectangular parallelepiped shape as shown in FIG. 6 in which only one surface on the door end side is open. It is also possible to have a shape in which the horizontal width of the side surface increases as the side surface approaches the vertical center portion of the side surface.

The shape that the door body 1e can take is limited by the fact that the elastic body 5e can be installed and the shape of the latch 3e and the operation unit 7e that you want to install, but there are no other major restrictions. ..
Further, as in the above Examples 1 to 3, the door body 1e may be stored in at least a part of the door case 2e, and even if the entire door body 1e is stored in the door case 2e. good. It is also possible to design the entire door so that the horizontal length of the door body is shortened and the horizontal length of the door case 2e is increased accordingly.

(6) Sixth Embodiment The door F of the sixth embodiment of the present invention will be described with reference to FIGS. 7 and 8.
A sixth embodiment is a door F having a structure in which the door F is slid in a horizontal direction parallel to the door surface to release the latch portion from the latch receiver, and the hinge 15 is provided with this slide structure. The door F is characterized by this. It is one of the slide type doors described above.
FIG. 7 is a schematic perspective view of the hinge 15 in the door E of the sixth embodiment as viewed from diagonally above. FIG. 8 is a plan view of the hinge 15 in the door E of the sixth embodiment as viewed from above.

The door F of the sixth embodiment is a door that can be opened only on one side of both door surfaces. In this respect, it is common with the first to fifth embodiments. FIG. 7 shows, as an example, a hinge 15 in a door F in which one wing 15b of the hinge 15 is fixed to the wall on the door tail side of the door F and can be opened and closed around the core rod 15c of the hinge 15.

Regarding the door body 1f, the latch portion is formed so that at least a part of the side surface on the door end side protrudes, and has a structure in which the latch portion is accommodated in the latch receiver at the closed position of the door F. It is the same as the embodiment.
Since the door F according to the sixth embodiment is the slide type door described above, it is common with the fifth embodiment. The operation unit for fulfilling the slide function is substantially the same as the operation unit of the fifth embodiment.

As shown in FIGS. 7 and 8, in the hinge 15, the wings 15b on the wall side are not different from the normal hinges, but the other wings form a U-shape in a plan view by the three plates. It is shaped like a hinge.
The three plates refer to a pair of opposed flat plate portions 15h and 15j and a connecting plate portion 15i that connects the flat plate portions to each other. A core rod 15c, which is the center of rotation of the hinge 15, is provided on one of the sides in contact between the flat plate portions 15h and 15j and the connecting plate portion 15i.
In FIGS. 7 and 8, one or more horizontally extending slit holes 15f formed in the pair of flat plate portions 15h and 15j are provided inside the U-shape, and the slit holes 15f are provided along the slit holes 15f. It shows how the door body 1f is held by the slidable slide member 15g.
As an example of how to hold the door body, in FIGS. 7 and 8, a method of forming a through hole in the door body 1f and passing a slide member 15g through the through hole can be considered. The number of slide members 15g is preferably at least two in total, including the slide members 15g attached to all hinges 15. This is because it is difficult to stop the force in the direction in which the door body 1f rotates around the slide member 15g if there is only one. The number of through holes may be provided in the door body 1f according to the number of slide members 15 g.
As another method for holding the door body 1f, it is conceivable to provide a recess in the door body 1f without providing a through hole and to support the slide member by fitting the slide member from both sides of the door surface. As for the number of recesses in this case, it is desirable to provide two or more recesses on one side of the door surface, as in the case of the number of through holes.

In the fifth embodiment, the elastic body 5e is installed in the door case 2e, whereas in the sixth embodiment, the elastic body 5f is installed in the hinge 15.
As shown in FIG. 7, it is inside the wing 15d on the door side, that is, inside the U-shape formed from the pair of opposing flat plate portions 15h, 15j and the connecting plate portion 15i connecting the flat plates. The elastic body 5e is installed so as to urge the door body 1e toward the door tip side.
For fixing the elastic body 5e, a method of installing the elastic body 5e via a support member or the like can be considered.

In the first, second, third, and fifth embodiments, the door case is used to enable movement such as rotation or sliding of the door body so that the latch portion integrated with the door body is released from the latch receiver. By providing an elastic body, it played a role in realizing a mechanism that can return the state of the door body that was unlatched to the state of the original door body that does not apply force to the operation part without applying manual operation. ..
In the sixth embodiment, since the elastic body 5f exists in the hinge 15, the mechanism is completed in the hinge 15. Therefore, the door F in the sixth embodiment is configured not to have a door case.
Since the door body 1f can be supported only by the hinge 15, it is possible to adopt a structure in which the weight of the door body 1f does not apply a force from the lower contact point or contact surface of the door body 1f toward the floor. .. It is desirable to have such a structure for the smooth opening and closing of the door.
Further, as shown in FIG. 8, by providing the elastic body 5f inside the hinge 15, a gap is generated between the side surface of the door body 1f on the door tail side and the connecting plate portion 15i of the hinge 15. Therefore, in order to have a door shielding function, a shielding plate 16 may be provided on the hinge 15 as shown in FIG. 7. The shielding plate 16 may be provided on the outer surface of the hinge 15 of the flat plate portions 15h and 15j, and may be provided on either or both of the two flat plate portions 15h and 15j. There may be various methods such as screwing as a method of providing a shielding plate on the outer surface of the hinge 15 of the flat plate portions 15h and 15j. When there is a gap between the flat plate portion 15h and the flat plate portion 15j and the door main body 1f, the shielding plate 16 is the flat plate portion 15h, as long as the sliding of the door main body 1f for releasing the latch is not hindered. It can also be provided inside the hinge 15 of 15j.

(7) Seventh Embodiment The door G of the seventh embodiment of the present invention will be described with reference to FIGS. 9 (a) to 9 (d). 9 (a) is a schematic perspective view of the door G according to the seventh embodiment as viewed from diagonally above, and FIG. 9 (b) is a part of the seventh embodiment on the door end side of the slide body. It is a schematic front view which looked at the periphery of the operation part of a door from the front in the case where the latch part is formed by protruding. (C) is a schematic front view of the periphery of the operation portion of the door as viewed from the front in the case where the latch portion is formed by projecting the entire door end side of the slide body in the seventh embodiment.

The door G of the seventh embodiment is a door that can be opened only on one side of both door surfaces. In this respect, it is common with the first to sixth embodiments. FIG. 9 shows a door G in which the wings on the wall side of the hinge 6 are fixed to the wall on the door tail side of the door G as an example, and the door G can be opened and closed centering on the core rod of the hinge 6.
The seventh embodiment relates to the above-mentioned slide type door and does not have a door case, and is common to the sixth embodiment in that respect.

As shown in FIGS. 9 (b) and 9 (c), a cavity 10 is formed on a part of the side surface of the door body 1 g on the door end side, and the door body 1 g located on both sides of the cavity 10 is interposed therebetween. A part of the member is cut out from the door end side to the door end side by a predetermined length. The cut length of the door surface member is shorter than the depth length of the cavity 10. Since the latch portion is housed in the latch receiver, the slide body 8 is slid toward the door end side so that the slide body 8 does not come off to both sides of the door surface. It is desirable that at least a part of the door is stored in 1 g of the door body. Further, if the notch depth is too long, the elastic body 5g may be visible when the door body 1g is viewed from the front of the door in a state where the latch portion 3g protrudes toward the door end side of the door body 1g. This is not desirable from the standpoint of the door shielding function, as it is possible.
FIG. 9 shows the case where the shape of the hollow portion 10 is a rectangular parallelepiped, but as another example, the slide body 8 slides inside the hollow portion 10, and the sliding body 8 is affected by the door end side portion of the slide body 8. As long as the latch portion to be formed can be accommodated in the latch receiver or can be unlatched, various shapes of the cavity portion can be taken.
However, when the slide body 8 slides in the cavity 10, it is preferable that there is no deviation on a plane orthogonal to the sliding direction in order to smoothly exert the original function of opening and closing the door.

A seventh embodiment relates to a door G including a sliding body 8 slidable in the cavity 10, as shown in FIG. As described above, the slide body 8 is preferably shaped so as to fit into the cavity 10.
In the seventh embodiment, the latch portion 3g is formed so that at least a part of the side surface of the slide body 8 on the door end side is projected. As shown in FIG. 9 (b), not only a shape in which a part of the side surface of the slide body 8 on the door end side is projected, but also all the side surfaces of the slide body on the door end side as shown in FIG. 9 (c). In other words, it is possible to take a structure in which the slide body 8 itself is also a latch portion. However, depending on the shape of the latch receiver, the shape of the latch portion 3g is restricted.
The closed position position of the door G is a state in which the slide body 8 itself or a portion where a part of the slide body 8 protrudes is housed in the latch receiver.

The door G of the seventh embodiment is provided with an elastic body 5g which is arranged in the cavity 10 and for urging the slide body 8 toward the door end side. That is, when no manual operation force is applied, the latch portion 3g is in a state of protruding toward the door end side from the door end side side surface of the door body 1g.
Therefore, when the latch portion 3g shifts from the state of being released from the latch receiver to the state of being accommodated in the latch receiver, a force toward the door end is applied to the operation portion 7g in order to accommodate the latch portion 3g in the latch receiver. There is no need.
In order for the latch portion 3g to be smoothly accommodated in the latch receiver without applying a manual operation force against the elastic body 5g, the door of the latch portion 3g that comes into contact with the latch receiver during the transition to the closed state. It is desirable that the surface on the back surface 30b side has a smooth curved surface. The latch portion 3a shown in FIG. 1 according to the first embodiment has one possible shape.

In the seventh embodiment, the operation unit 7g is provided on the door front surface 30a side and the door back surface 30b of the slide body 8.
Since the slide body 8 and the hollow portion 10 are in a collision relationship, when the slide body 8 is provided with the operation portion 7g and the slide body 8 is slid to release the latch portion 3g from the latch receiver, the operation is performed. The portions 7g collide with each other at the notched line of the door surface member, and the sliding stops. This notch line 14 serves as a stopper.
Further, FIG. 9D is an example in which the slide body 8, the operation unit 7 g, the latch unit 3 g, the cavity portion 10, and the elastic body 5 g are provided below the door body 1 g. In this case, it is assumed that the operation of the operation unit 7g is performed by the foot. As shown in this figure, when the operation unit 7g is viewed from the door end side, if the shape is such that the upper side of the operation unit 7g is curved, it becomes difficult to step on the operation unit 7g from above, so step on it. It is possible to avoid aged deterioration of the operation unit 7g due to the above.

Although the present invention has been described above with reference to the drawings showing some embodiments of the present invention, the present invention also includes embodiments in which the characteristic configurations of the respective embodiments are combined. Further, although a door that can be opened only on one side of both door surfaces has been described as an example, the present invention can be applied to a door that can be opened on any of both door surfaces. .. Further various modifications are possible as long as it is in line with the gist of the present invention.
