Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door having characteristics in components related to an opening/closing operation, a sliding door with a latch mechanism having the same characteristics, a lockable sliding door with a latch mechanism having the same characteristics, and an operation part structure related to the opening/closing operation of the door.

A typical sliding door is provided with an operation member that protrudes outward for opening and closing, and a finger is hooked or gripped there to slide the sliding door to open and close (Patent Document 1), or an operation member with a concave shape is provided. , the sliding door is slid and opened/closed by putting a finger there (Patent Document 2).
Regardless of whether the operation member has a protruding shape or a concave shape, when considering individual differences so that various people can use it, the operation member is elongated in the vertical direction, and the entire sliding door The ratio of the area occupied by the operating member to the In addition, as the weight of the sliding door increases, the need to increase the projecting height of the operating member and the depth of the concave shape increases, so the area occupied by the operating member increases.

If the sliding door itself is not thick, or if the sliding door cannot be thickened due to the needs of the installation environment, etc., it is necessary to avoid that the operating member protrudes more or becomes a deeper concave shape. The more restrictive the design in this respect, the more likely the sliding door will be of poor operability. There is a need for a sliding door construction that makes the most efficient use of the limited space, and above all that allows for relatively small occupied areas for the operating components. Realization of this also leads to maintenance of operability.

The object of the present invention is to provide a structure that can relatively reduce the area occupied by the components involved in the operation of the sliding door (operation part structure) in order to make effective use of the limited space. That is. In other words, the object is to provide a structure in which an opening/closing operation region for opening/closing operation by a part of the body is made to appear or widen by a specific operation. For example, by storing at least a part of the components related to the operation in the sliding door when not in operation, the components related to the operation do not protrude from the sliding door surface, or the protrusion is relatively low. To provide a structure that makes it possible to eliminate or shallow the depressions of components involved in the operation of the.

Another object of the present invention is to provide a sliding door that achieves the above object with a latch structure. This is to prevent unintentional opening of the sliding door by adopting a structure that requires some effort to open the sliding door. Many sliding doors do not have a latch structure, but there are many situations where it is desirable to prevent unintended opening of the sliding door. For example, when you want to prevent the sliding door from being opened by the vibration of an earthquake and scattering the contents inside (Patent Document 3), when you want to prevent children from entering without permission, or when you want to prevent the sliding door from being closed and open slightly due to deterioration of the sliding door. When it is desired to prevent a state from occurring, a latch function may be required although locking is not necessary.

In the description of the sliding door according to the present invention, both sides that are wide surfaces of a general sliding door are referred to as "sliding door surfaces", and both sides that are wide surfaces of doors including general sliding doors and hinged doors are referred to as "door surfaces". The thickness of the sliding door in the direction perpendicular to the sliding door surface is defined as "sliding door thickness", and the thickness of the door in the direction perpendicular to the door is defined as "door thickness". The sliding door or the half point of the thickness of the door is called "the center of sliding door thickness" and "the center of door thickness" respectively. The vertical lines passing through these centers are called the "sliding door thickness center line" and the "door thickness center line", respectively. The planes formed by these center lines are defined as the "center plane of the thickness of the sliding door" and the "center plane of the thickness of the door", respectively.
The sliding door thickness direction, the door thickness direction, the direction perpendicular to the sliding door surface, and the direction perpendicular to the door surface refer to the same direction.

(1) 1st Embodiment With reference to FIG. 1, the sliding door of the 1st Embodiment of this invention is demonstrated.
First, in any embodiment, the sliding door 1 of the present invention is formed with a through-hole portion 2 having a hole penetrating from one sliding door surface to the other sliding door surface.
In general, when the sliding door is slid toward the door trailing edge and opened, the sliding door is not completely accommodated in the buttress wall, and the portion that protrudes from there is called the door leftover portion. Formed part of the range.
The number of installed through-holes 2, installation locations, and shape should be within the range of the door left behind, and should be penetrated in the direction perpendicular to the sliding door surface, that is, the formed through-holes 2 should be columns. There are no major restrictions except for
In this embodiment, the through-hole portion 2 on the upper side of FIG. 1(a) is a range formed by following the outer frame of the portion made by the solid and dotted lines, and is approximately vertically aligned with the quadrangle from the viewpoint of the figure. It takes a shape like an oval. The through-hole portion 2 on the lower side of the figure is a range formed by tracing the outer frame of the portion defined by the solid and dotted lines, and has a substantially square shape. Assuming that the sliding door 1 in FIG. It is assumed to be related to foot manipulation.

The sliding door 1 of this embodiment has a first receiver 7 protruding from one sliding door surface to the through hole portion 2 . There are no major restrictions on the shape of the protrusion. In this embodiment, the surface visible in FIG. 1(a) is defined as one sliding door surface.
In the through-hole portion 2 on the upper side of FIG. In the through-hole portion 2 on the lower side of FIG.
As shown in the figure, their first receivers 7 have a surface flush with one of the sliding door surfaces. Although it is possible to use a material different from that of the sliding door 1 only for the portion related to the first receiver 7, even in that case, the surface is provided flush with one of the sliding door surfaces.
Moreover, the sliding door 1 of this embodiment has a second receiver 8 protruding from the other sliding door surface to the through hole portion 2 . The second receiver 8 is formed in the same manner as the first receiver 7, and is formed on the other sliding door surface opposite to the one sliding door surface on which the first receiver 7 is formed. The first receiver 7 and the second receiver 8 do not have to be symmetrical with respect to the center plane of the thickness of the sliding door. However, in the case of plane symmetry, it is possible to form guide grooves that are not visible from the outside for sliding a sliding member 20, which will be described later. For example, in the through-hole portion 2 on the upper side of FIG. 1( a ), a first elliptical receiver 7 and a second receiver 8 indicated by dotted lines are formed on both sides of the sliding door surface, and a constant cross-sectional area is formed between them in the thickness direction of the sliding door. A part of the through-hole portion 2 is formed. A part of the through-hole portion 2 serves as a guide groove for stably sliding a sliding member 20, which will be described later.

As for the method of providing the first receiving portion 7 and the second receiving portion 8, it is possible to provide them later after forming the through hole portion 2, and to form the through hole portion 2, the sliding door 1 is penetrated. In some cases, it is also possible to provide the first receiving portion 7 and the second receiving portion 8 so as to penetrate therethrough.

Although there is no major limitation on the number of the first receivers 7 and the second receivers 8 provided for one through-hole 2, the number and shape of the receivers may naturally be limited in terms of practicality and design. The upper through-hole portion 2 in FIG. 1A has two first receivers, and the lower through-hole portion 2 has four first receivers.

The first receiver 7 and the second receiver 8 have surfaces that are flush with the sliding door surface. Further, the surfaces of the receivers 7 and 8 other than the flush surfaces may be curved surfaces.
However, when the receivers 7 and 8 have a constant cross-sectional area in the sliding door thickness direction, the surface of the receivers 7 and 8 on one side of the sliding door and the surface of the receivers 7 and 8 on the other side of the sliding door become parallel. In this case, as long as the sliding body 20 is similarly provided with a surface such that one sliding door surface side and the other sliding door surface side are parallel, the receivers 7 and 8 and the sliding body 20 can slide. There will be a facet collision at both ends, leading to stable slide body 20 sliding and stopping. Contact on this surface also contributes to the dispersion of the force accompanying the collision, leading to durability for long-term use of the sliding door 1 .
Moreover, the thickness of the sliding door thickness direction of the first receiving part 7 and the second receiving part 8 has certain restrictions from the viewpoint of achieving the purpose. A sliding member 20 is disposed in the through hole 2 so as to be slidable between the first receiving member 7 and the second receiving member 8 in the direction perpendicular to the sliding door surface, and the sliding movement of the sliding member 20 is used to open and close the sliding door 1. Since it is performed to make the opening/closing operation area 5 appear in the through hole portion 2 or to expand it in the through hole portion 2, it is preferable that the sliding range is wider. It is preferable that the thickness of 8 is as thin as possible.

The sliding door 1 has a sliding body 20 . The sliding body 20 is provided in the through-hole portion 2 and is slidably arranged between the first receiving part 7 and the second receiving part 8 in the direction perpendicular to the sliding door surface. As can be seen from the cross-sectional view of FIG. 1(c), the sliding body 20 can slide left and right in the figure up to a position where it collides with the first or second receiver in the through hole portion 2. As shown in FIG.
The sliding body 20 only needs to slide within the through-hole portion 2 and does not need to be fitted with the through-hole portion 2 . However, in order to block the view from one sliding door surface side to the other sliding door surface side, it is desirable to have a size that covers at least that portion of the through hole portion 2 that is visible from the outside.
The slidable space between the first receiver 7 and the second receiver 8 in the upper through-hole portion 2 in FIG. It is shaped like a quadrilateral with approximately elliptical shapes attached to the top and bottom of the square. Since the sliding body 20 has a shape that allows it to slide in this space in the direction perpendicular to the sliding door surface, its shape is substantially the same as that of the through hole portion 2, for example, in a plane parallel to the sliding door surface. It is conceivable that only the portion surrounded by the dotted line in (a) has substantially the same shape.
Similarly, the slidable space between the first receiver 7 and the second receiver 8 in the lower through-hole portion 2 in FIG. ), it becomes a square. The sliding body 20 can have, for example, a substantially square shape that is substantially the same shape as the through-hole portion 2 on a plane parallel to the sliding door surface. Due to the thickness of the sliding body 20 in the sliding door thickness direction, it is possible to prevent the sliding body 20 from falling in the direction perpendicular to the sliding door surface.
The contact surface between the through-hole portion 2 and the sliding body 20 may be made of a metal with low friction so that the sliding body 20 slides smoothly.
Since the through-hole portion 2 is for forming a space in which the sliding bodies 20 slide, the same number of sliding bodies 20 as the through-hole portions 2 are inevitably provided.

As another form, the sliding door 1 of this embodiment can also have an elastic body (not shown). This elastic body can be used so that the sliding body 20 is positioned at the center of the thickness of the sliding door when no human force is applied to the sliding body 20 . For example, it can be provided between the slide 20 and the receivers 7,8. In order to prevent fingers from touching the elastic body during the sliding operation of the sliding body 20, it should be provided inside the through-hole part 2 and in a portion that cannot be visually recognized from the outside by the first or second receiver. is preferred. For example, it is the area of the dotted line in the upper through-hole portion 2 in FIG. 1(a).

In this embodiment having the above configuration, the first receiving part 7 and the second receiving part 8 are provided on both sides of the sliding door surface of the through-hole part 2, so that the sliding body 20 sliding therebetween does not fall out of the sliding door 1. can be prevented.
Since the sliding door is usually opened/closed by hooking a part of a person's body on the sliding door 1, the opening/closing operation region 5 of the sliding door 1 is positioned where a part of the body can be hooked. Which part of the body to hang depends on the position of the installation place. In all embodiments of the present invention, the opening/closing operation area 5 will be formed within the through-hole portion 2 .
An opening/closing operation area 5, which is an operation area for opening and closing the sliding door 1, appears in the through-hole 2 or is enlarged within the through-hole 2 by sliding of the sliding body 20. As shown in FIG. When the sliding body 20 shown in FIG. 1(c) is located near the center of the thickness of the sliding door, the width of the opening/closing operation area 5 in which the finger or the like is hung in order to open/close the sliding door may be insufficient in the direction perpendicular to the sliding door surface. However, if the sliding body, which is the horizontal direction in the figure, is slid in the direction perpendicular to the sliding door surface until it hits the first or second receivers 7 and 8, the opening/closing operation area 5 is expanded by the sliding distance. , operation with a finger or the like becomes possible.
When the sliding body 20 shown in FIG. 1(c) is in the vicinity of the sliding door surface, there is substantially no opening/closing operation area 5 for the operator on the sliding door surface side. The opening/closing operation area 5 can be made to appear in the through-hole portion 2 by the operator pushing the sliding body 20 to the opposite side of the sliding door surface.

Since the opening and closing operation area 5 is a part where the operator operates the sliding door, the operator can operate the sliding door according to the degree of freedom regarding the installation location, the number of installations, and the shape of the through hole 2, the sliding body 20, and the first and second receivers 7 and 8. It is possible to design the sliding door 1 according to the user's request, including the part of the body that the user wants to use, the environment in which the sliding door is installed, and the user's request.
It is possible to design them so that opening and closing operations can be performed with various parts such as fingers, elbows, knees, feet, etc. For example, as a countermeasure against infection, the sliding body 20 can be slid vertically on the sliding door surface by using the legs without using fingers. It is possible to design the position and shape of each component suitable for that.
In addition, since a part of the through-hole portion 2 and the shapes of the first and second receivers 7 and 8 can be visually recognized from the appearance of the sliding door 1, the number of components to be installed, the locations to be installed, and the shape of each component can be freely designed. , making it easy to give design to the sliding door, which is also advantageous.

(2) Second Embodiment A second embodiment will be described with reference to FIG. Since the functions performed by each component of this embodiment are common to those of the first embodiment, the description of those functions will be omitted.
If the sliding body 20 slides only between the first and second receivers in the same embodiment as in the first embodiment, the smaller the thickness of the sliding door, the smaller the area of the opening/closing operation area 5, which is practical. sex is lost. Therefore, the purpose of showing the second embodiment is to further expand the area of the opening/closing operation area 5 by allowing a part of the sliding body 20 to slide over the sliding door surface. Furthermore, by allowing such sliding, it becomes possible for the sliding body 20 to have the same thickness as the thickness of the sliding door. may have.

The difference regarding the components from the first embodiment is that the sliding door 1 has a first stopper and a second stopper. These can be integrally molded as a part of the sliding body 20 in the manufacture of the sliding door 1, or can be provided on the sliding body afterward. In the latter case, it may be made of a material different from that of the sliding body 20 .
The first stopper 21 and the second stopper 22 correspond to the first receiver 27 and the second receiver 28, respectively. , and the sliding in the other direction stops due to the collision between the second stopper 22 and the second receiver 28 .
This state is shown in FIG. 2(b), and the drawing on the left side shows a state in which the sliding body 20 stops sliding due to the second stopper 22 colliding with the second receiver 28. As shown in FIG. The central figure shows a state in which the sliding body 20 having the same width as the sliding door thickness is accommodated in the through-hole portion 2 of the sliding door 1, and the opening/closing operation area 5 does not exist when viewed from either side of the sliding door surface. The drawing on the right shows a state in which the first stopper 21 collides with the first bearing 27, and the sliding body 20 stops sliding. The figure on the right shows a state in which the sliding body 20 has slid over the sliding door surface on the front side of FIG. 1(a).

In order to realize this function, the surface of the first stopper parallel to the sliding door surface has substantially the same surface area as the surface of the first receiver 27 parallel to the sliding door surface. It is mounted so that the surface of the first stopper 21 is located at a position where the surface of the 1 receiver 27 is moved substantially parallel in the thickness direction of the sliding door. The second receiver 28 and the second stopper 22 are also mounted so that the same relationship holds. For example, as shown in FIG. 2(c), the same front surface as in FIG. In view, the first stopper 21 and the second stopper 22 are positioned so as not to overlap each other. As a result, the surfaces of the corresponding first receiver 27 and second receiver 28 that are parallel to the sliding door surface do not overlap in the thickness direction of the sliding door.
Although the positions where the first stopper 21 and the second stopper 22 are provided are restricted so that they do not overlap as described above, they are positioned so that they appear to be adjacent when viewed from the front as shown in FIG. 1(c). It doesn't have to be on, it can be far away. In addition, it is not necessary to provide them above and below the vertical direction as shown in the figure.

As a structure related to the above functions, the sliding door 1 has a first receiver 27 and a second receiver 28 as in the first embodiment. The sliding door 1 has a surface flush with the surface of the sliding body 20 on the side of the other sliding door surface, has a first stopper 21 having a constant cross-sectional area in the sliding door thickness direction, and It has a second stopper 22 that has a surface that is flush with the surface side surface and that has a constant cross-sectional area in the sliding door thickness direction.
As shown in FIG. 2(c), it can be seen that the second stopper 22 has a surface that is flush with one surface of the sliding body 20. As shown in FIG. Although not shown, when the sliding body 20 is viewed from the opposite direction, the first stopper 21 has a surface that is flush with one surface of the sliding body 20 .

The stoppers 21, 22 and the receivers 7, 8 have a predetermined thickness in the thickness direction of the sliding door. In order to distribute the forces associated with the impact, the stops 21, 22 and the catches 7, 8 are provided to impact each other over their entire surfaces.

The first receiver, the second receiver, the corresponding first stopper, and the second stopper in this embodiment can be provided at a plurality of locations as long as the functions described above can be achieved. However, considering practicality and design cost, basically, as shown in the embodiment and FIGS.

If the sliding body 20 is near one of the sliding door surfaces or has a thickness equal to or greater than the thickness of the sliding door, the opening/closing operation area 5 does not exist for the operator standing on the one sliding door surface side. In this case, the opening/closing operation area 5 can be made to appear in the through hole portion 2 by the operator pushing the sliding body 20 toward the other sliding door surface side.
In addition, even when a part of the opening/closing operation area 5 is visible to the operator, the opening/closing operation area 5 can be moved to the through hole portion by pushing the sliding body 20 toward the other sliding door surface side as long as the sliding body 20 can slide. 2 can be expanded.

Other structures are the same as those of the sliding door 1 of the first embodiment, so the advantages of this embodiment are also common.

(3) Third Embodiment A third embodiment will be described with reference to FIG. The sliding door 1 of this embodiment is common to the first and second embodiments in that it has a through-hole portion 2, and the description thereof will be omitted.
The sliding door 1 of the present embodiment does not have the sliding body 20, but instead has a protruding member 32, which is pushed out in the direction perpendicular to the sliding door surface to make the open/close operation area 5 appear or expand in the through hole 2.
The configuration for realizing this function differs from the first and second embodiments in that the base arm portion 30 serving as the base of the structure from which the protruding member 32 protrudes is arranged on the inner surface of the through hole portion 2. is. A base arm portion 30' is fixed to the inner surface of the through-hole portion 2 facing the inner surface thereof. The connection arms 31, 31' can be connected to any of the base arms 30, 30'.
FIG. 3(f) is a schematic perspective view showing how the protruding member 32 protrudes from the sliding door 1 on one inner surface. remains fixed.

Next, connecting arms 31, 31' are connected between the base arms 30, 30' and the protruding members 32 in order to realize the above functions.
When the operator pushes out the protruding member 32 to displace the relative position of the protruding member 32 with respect to the connecting arms 31 and 31', and when the limit of the displacement is reached, the basic arms 30 and 30 of the connecting arms 31 and 31' are displaced. The position relative to 30' begins to shift. The relative position of the protruding member 32 with respect to the base arms 30, 30' is displaced by the amount of these displacements. Such a displaceable structure provides the action of projecting the projecting member 32 .
The projecting member 32 can be pulled out as well as pushed out. In this case, the projecting member 32 and the like move in the same manner as when the operator on the opposite side of the operator pushes it out.
The connecting arm portions 31, 31' can further connect a plurality of connecting arm portions 31, 31' as long as practicality and function are ensured. That is, one end of the connecting member 31, 31' is connected to the base arm or another connecting arm 31, 31', and the other end is slidably connected to the other connecting arm 31, 31' or the protruding member 32. will be In other words, one or more pairs of connecting arms 31 and 31' are connected to the base arms 30 and 30', and finally the other is not connected to anything and is positioned facing each other. Both ends of the projecting member 32 are connected to 31'.

In this embodiment, as shown in FIG. 3B, a connecting member 34 is used for the above connection. A connecting member 34 fixed to the connecting arms 31, 31' operates to slide within the base arms 30, 30', and a connecting member 34 fixed to the protruding member 32 moves between the connecting arms 31, 31'. The protruding motion of the protruding member 32 is realized by operating to slide within 31'. As an example of a structure that enables sliding, as shown in FIG. 3E, from the same viewpoint as FIG. Each shape is provided so as to fit and so that the connecting member 34 fixed to the connecting arms 31, 31' fits into the base arm.
As a whole, the base arm 30 and the base arm 30', and the connecting arm 31 and the connecting arm 31', with respect to the surface intermediate the inner surface to which the base arm 30 is fixed and the surface opposite thereto. The same number is arranged so as to be plane symmetrical.

In this embodiment, FIG. 3(c) shows an initial state in which no force is applied to project the projecting member 32 in the direction of the arrows shown in FIGS. 3(b) and 3(d). An elastic body 33 is provided so that the projecting member 32 is positioned at the center of the thickness of the sliding door in this initial state. As shown in FIGS. 3(b) to 3(d), in the base arms 30, 30′, the elastic body 33 is attached to one inner surface of the base arms 30, 30′ and the connecting arms 31, 31′. It is connected between fixed connecting members 34 . Similarly, within the connecting arms 31 , 31 ′, an elastic body 33 is connected between one inner surface within the connecting arms 31 , 31 ′ and a connecting member 34 fixed to the protruding member 32 .
The protruding member 32 is urged in the direction perpendicular to the sliding door surface against the elastic body 33, and the relative positions of the protruding member 32 and the connecting arm portions 31, 31' with respect to the base arm portions 30, 30' are displaced. The protruding member 32 is protruded from the state of (c) to the state of FIG. 3(b) or (d). When the bias is stopped, the protruding member 32 returns to the position shown in FIG. 3(c).
Based on the position and size of the through-hole portion 2 in this embodiment, it is assumed that the foot will be operated. can be made to protrude.
As another embodiment, when the through hole portion 2 and the protruding member 32 and the like are in a position suitable for manual operation and the protruding member 32 has a cylindrical shape as shown in FIG. An operation in which the projecting member 32 is grasped and pushed is assumed. In the hand grip configuration, the protruding member 32 can also be pulled to open the sliding door.

FIG. 3( f ) shows a state in which the protruding member 32 protrudes, and along with this, the opening/closing operation area 5 is enlarged within the through-hole portion 2 . When the opening/closing operation area 5 does not substantially exist in the initial state, the opening/closing operation area 5 appears due to the projection of the projecting member 32 .
The function of displaying or enlarging the opening/closing operation area only when necessary contributes to effective use of the limited space. The opening and closing operation area for sliding door operation is usually provided on both sides of the sliding door, and an opening and closing operation area that projects from the sliding door surface of a shape suitable for the operation is provided for gripping or hooking by hand, or for hooking by hand , an opening/closing operation area recessed from the sliding door surface having a shape suitable for the operation is provided.
If the opening/closing operation area is provided on both sides of the sliding door surface, the sliding door occupies a space including the protruding portions on both sides, and if the opening/closing operation area is recessed on both sides of the sliding door surface, both sides of the sliding door occupy space. The sliding door must have a thickness that takes into account the depth of the recess. In this respect, the protruding structure of the present embodiment creates an open/close operation area for each protruding operation, so that the thickness of the sliding door can be designed to be relatively thin. This feature is even more advantageous when a greater hooking depth is required, such as when using the foot.

(4) Fourth Embodiment A fourth embodiment will be described with reference to FIG. It is common in that the through-hole portion 2 is provided with the above-described embodiment, and the features and advantages thereof are common, so a description thereof will be omitted.
This embodiment does not have the sliding body 20 in the first embodiment, but instead has a rotating body 40 that can rotate with respect to the sliding door. As shown in FIG. 4( a ), in the front view of the sliding door 1 , the rotating body 40 is accommodated in the through hole portion 2 . To enable the rotation of the rotating body 40 within the through hole 2, a rotating member 41 is provided, the axis of the rotating member 41 passing through two opposite points on the inner surface of the through hole 2. is provided as follows. For example, like the rotating body 40 provided in the upper through-hole portion 2 in FIG. Like the rotating body 40, it is also possible to provide shafts at two points on the left and right at the same viewpoint. Their axes do not necessarily lie in the center plane of the sliding door thickness. However, in order to provide the same operational feeling on both sides of the sliding door, it is preferable that the axis is present on the center plane of the thickness of the sliding door.

As shown in FIG. 4B, the upper rotating body 40 of the two rotating bodies 40 is rotated from the state shown in the left drawing to the state shown in the middle drawing and then to the state shown in the right drawing. Thus, the opening/closing operation area 5 for opening/closing the sliding door 1 can be enlarged within the through hole portion 2 . As for the rotating body 40 on the lower side, the opening/closing operation area 5 can be expanded by rotating it from the state shown in the central figure to the state shown in the left and right figures. If the rotating body is provided close to one of the sliding door surfaces, the opening/closing operation area 5 does not exist when viewed from the operator on the sliding door surface side. appears in the through-hole portion 2 .

Providing the rotating body 40 in the through hole 2 and rotating it means that the width of the entire sliding door thickness can be used as the opening/closing operation area 5, and the limited sliding door thickness is effectively used for the operation. It will be possible. In the range where the above functions can be realized, various rotations of the rotating body can be realized, which is advantageous in terms of easy designability.

(5) Fifth Embodiment A fifth embodiment will be described with reference to FIG.
This embodiment is characterized in that, in addition to the sliding door in the first to fourth embodiments, a protruding auxiliary operating portion 42 is further provided on both sides of the through-hole portion 2 on the front end side and door rear end side.
In FIG. 5(a), the auxiliary operation parts 42 are fixed on both sides of the upper through-hole 2 in which the rotating body 40 is provided, and the auxiliary operation parts 42 are fixed on both sides of the lower through-hole 2 in which the sliding body 20 is provided. An example in which the portion 42 is fixed is shown.
The auxiliary operation portion is effective when the area necessary for the operation of the enlarged or appearing opening/closing operation area 5 cannot be secured only by sliding the sliding body 20 or rotating the rotating body 40 . For example, as shown in FIG. 5(b), the opening/closing operation region 5 expanded by rotating the rotating body 40 in the upper through-hole portion 2 is larger than that in FIG. It can be seen that the area for operation is widened by the amount of .

As shown in FIG. 5(b), it is also possible to design so that the sliding member 20 can slide beyond the inner surface of the lower through-hole portion 2 to the area of the auxiliary operation portion 42. As shown in FIG. In this case, the area of the opening/closing operation area 5 can be made wider than when the auxiliary operation portion 42 is simply provided.

(6) Sixth Embodiment A sixth embodiment will be described with reference to FIG.
A feature of the sixth embodiment is that in the sliding door 1 provided with the sliding body 20, the auxiliary operating portion 50 moves in the direction opposite to the sliding direction in conjunction with the sliding. The auxiliary operation part 50 is installed in the through hole part 2 indicated by the dotted line in FIG. 6(b).
As shown in FIG. 6(a), when the sliding body 20 is slid upward in the drawing, the auxiliary operating portion 54 moves downward. Compared to the opening/closing operation area 5 that is enlarged or appears by simply sliding the sliding body 20, the area as the opening/closing operation area 5 is widened by the amount of movement beyond the sliding door surface of the auxiliary operation part 50. I understand. Since the auxiliary operation unit 50 has a wide surface on the vertical plane orthogonal to the sliding door surface, this wide surface is used for the opening and closing operation.
This feature also contributes to effective utilization of the space with respect to the limited thickness of the sliding door and easier opening and closing operation of the sliding door.

In order to realize this function, the sliding door 1 of this embodiment includes a gear 51 that rotates as the rotating body 40 rotates, as shown in FIG. 6(a). Although many structures are conceivable in which the gear rotates as it rotates, in this embodiment, as an example, there is a connecting member 53 fixed to the sliding body 20 as shown in FIG. A first rack 52 having linear teeth in the thickness direction of the sliding door is provided so that the first rack 52 moves in the thickness direction of the sliding door in conjunction with the sliding of the sliding body 20 . A gear 51 meshing with the teeth of the first rack rotates in conjunction with the movement of the first rack. The gear 51 according to this embodiment has two stages, and the teeth of the upper stage mesh with the teeth of the first rack 52 . The upper teeth of the first rack 52 and the gear 51 constitute a rack and pinion structure.

The auxiliary operating part 50 has a second rack 54 with straight teeth. As shown in FIG. 6( a ), the teeth of this second rack mesh with the lower teeth of the gear 51 . The second rack 54 and the lower teeth of the gear 51 constitute a rack-and-pinion structure. As a result, the gear 51 rotates in conjunction with the sliding of the sliding body 20, and the auxiliary operating portion 50 including the second rack 54 moves in conjunction with this. From the ratio of the width of movement of the auxiliary operating portion in the thickness direction of the sliding door to the distance of movement of the sliding body, the ratio of the numbers of teeth of the upper and lower stages of the gear 51, and thus the number of teeth of the first and second racks, can be determined.
Components such as the gear 51 for interlocking the movements of the sliding body 20 and the auxiliary operation part 50 are normally installed inside the sliding door 1 as in this embodiment, so as to effectively utilize the space in which the sliding door 1 is installed. From this point of view, it is preferable. However, the installation of components for interlocking is not limited to being completed only inside the sliding door.

In another embodiment, the sliding door 1 of the sixth embodiment further has an elastic body 55, as shown in FIGS. This is because, in the initial state in which no force is applied to slide the sliding member 20, the elastic member 55 is positioned so that the center of the wide surface of the auxiliary operating portion 50 and the center of the sliding member 20 in the thickness direction of the sliding door are near the center of the thickness of the sliding door. It acts to be located in
As shown in FIG. 6(b), the elastic body is provided between a part of the sliding body 20 and the inner surface of the sliding door 1 formed by the through-hole 2 and the first or second receiver 7 or 8. may be set to Since the sliding body 20, the connecting member 53, the first rack 52, the gear 51, the second rack 54, and the auxiliary operation part 50 are all interlocked, the elastic body 55 can be adjusted to any one of them so as to maintain their respective initial positions in the initial state. You can put it in position. For example, it is conceivable to equip the gear 51 with a spiral spring. The location and the number of elastic bodies to be installed have a degree of freedom under the constraints that the sliding of the sliding body 20 should not be too much of a burden and that each component should be able to smoothly return to its initial position in the initial state.

(7) Seventh Embodiment A seventh embodiment will be described with reference to FIG.
A feature of the seventh embodiment is that in the sliding door 1 provided with the rotating body 40, the auxiliary operating portion 68 moves in the sliding door thickness direction in conjunction with the rotation. Specifically, from the viewpoint of FIG. 7A, when the rotating body 40 indicated by the dotted line in FIG. The portion 68 moves downward. In the appearance of the sliding door 1, the portion surrounded by the dotted line shown in FIG.
Advantages brought about by the features of this embodiment are common to those of the sixth embodiment, and therefore are omitted.

In order to realize this function, first, a gear 64 that rotates in conjunction with the rotation of the rotating body 40 is provided. There are many possible methods for this interlocking, but in this embodiment, as shown in FIG. A pulley is provided and interlocked with a belt. Further, a gear 65 having a two-stage structure of a bevel gear and a spur gear is provided, and the bevel gear portion meshes with the gear 64 . Similarly to the auxiliary operating portion 50 of the sixth embodiment, the auxiliary operating portion 68 of this embodiment also has a rack 66 having linear teeth in the thickness direction of the sliding door. The rack 66 meshes with the spur gear portion of the gear 65 to form a rack and pinion structure. As a result, the auxiliary operating portion 68 moves in conjunction with the rotation of the rotating body 40 . The rotation angle of the rotating body 40 and the movement distance of the auxiliary operating portion 68 can be adjusted by adjusting the ratio between the number of teeth of the bevel gear and the number of teeth of the spur gear of the gear 65 .
Components such as the gear 64 for interlocking the movement of the rotating body 40 and the auxiliary operation part 68 are normally installed inside the sliding door 1 as in this embodiment, so as to effectively utilize the space in which the sliding door 1 is installed. From this point of view, it is preferable. However, the installation of components for interlocking is not limited to being completed only inside the sliding door.

As another embodiment, a structure in which an elastic body 67 is further provided in the sliding door 1 of the seventh embodiment can be considered.
In the initial state where no force to rotate the rotating body 40 is applied to the elastic body 67, the center of the wide surface of the auxiliary operating portion 68 and the center of the rotating body 40 in the thickness direction of the sliding door are positioned near the center of the thickness of the sliding door. provided to do so. If the rotating body 40 is not positioned parallel to the sliding door surface, it is possible to see through from one side of the sliding door to the other side, which is not preferable when the sliding door is used as a door. Therefore, the initial position in the initial state is significant in order to maintain the function of the sliding door that blocks the view.

The elastic body 67 may be provided in the auxiliary operating portion 68 as shown in FIG. Since it works, it may be provided at any part involved in these movements. Regarding the installation locations and the number of installations, the degree of freedom is limited under the constraints that the rotation of the rotating body 40 should not be too much of a burden, and that each component should be able to smoothly return to its initial position in the initial state. be.

Depending on the position of the elastic body 67, the auxiliary operating portion 68 is prevented from moving over the sliding door surface. Therefore, for example, when the auxiliary operating portion 68 is provided with the elastic body 67, the auxiliary operating portion 68 may have shapes as shown in FIGS. 7(b) to 7(d).
Specifically, from the viewpoint of FIG. 7(d), the auxiliary operation part 68 is projected on the far side (right side in FIG. 9(d)) and on the front side (left side in FIG. 9(d)) in the thickness direction of the sliding door. 7(b) and 7(c) when viewed from the front of the sliding door 1, and positioned so as not to overlap each other. Also in the through hole portion 2 visible from the exterior of the sliding door, a hole is formed so that the foot on the front side in the thickness direction of the sliding door can move to the front side beyond the surface of the sliding door. On the other hand, no hole is formed so that the leg on the far side in the thickness direction of the sliding door does not move forward beyond the surface of the sliding door. When the auxiliary operating portion 68 is moved, the part where the hole is not formed and the leg on the far side in the thickness direction of the sliding door come into contact with each other. Then, as shown in FIG. 7(d), an elastic body can be provided between them.
This structure allows the auxiliary operation part 68 to move over the sliding door surface and also allows the elastic body 67 to be provided. This construction also has the advantage that the view from one side of the sliding door to the other is always blocked.

(8) Eighth Embodiment An eighth embodiment will be described with reference to FIG.
A feature of the eighth embodiment is that the sliding door 1 of the first embodiment has a latch function.
As shown in FIG. 8A, the sliding door 1 has at least one set of elastic bodies 74 on both sides of the sliding body 20 in the direction perpendicular to the sliding door surface. In this embodiment, as shown in FIG. 8B, four sets of elastic bodies 74 are provided. One of the roles of this elastic body 74 is to align the center of the sliding door 20 in the thickness direction with the center of the sliding door 1 in the thickness direction in the initial state in which no force is applied to slide the sliding body 20 by a person. It's about getting together.

As a premise for explaining the latch function of this embodiment, the structure of the sliding door before the structure relating to the latch function and the sliding body 20 are provided will be explained with reference to FIG. 8(c). FIG. 8(c) is a schematic cross-sectional view from the same viewpoint as FIG. 8(b).
As described in the first embodiment, the through hole portion 2 is a hole penetrating the sliding door 1 in a direction perpendicular to the sliding door surface. In the present embodiment, the through-hole portion 2 is formed by the shape of the portion surrounded by the solid line from the viewpoint of FIG. Ultimately, the through-hole portion 2 visible from the exterior of the sliding door 1 is a portion surrounded by a rectangular dotted line, and the first receiver 7 is the portion surrounded by the solid line excluding the portion surrounded by the rectangular dotted line. Become. When viewed from the other sliding door surface side, the through hole portion 2 and the second receiver 8 having the same shape are provided.

The sliding door 1 in this embodiment is provided with a door leading opening 77 that is internally connected to the through hole 2 and opens to the door leading side surface of the sliding door 1, which is surrounded by a circular dotted line in FIG. 8(c). A door opening 77 is provided in the part. FIG. 8(d) is a schematic view of a part related to the latch mechanism in the sliding door of the present embodiment, viewed from the door tip side. When the door tip opening 77 is provided, it opens as shown. As shown in FIG. 8(b), the door opening 77 is connected to the through hole 2 inside the sliding door 1 as a space.
The purpose of providing the door-end opening 77 is to provide a latch portion 70 coupled to the sliding body 20 through the door-end opening 77 as shown in FIG. 8B to realize a latch mechanism.
As long as this purpose is achieved, the shape of the door opening 77 is arbitrarily determined.

The sliding door 1 is opened and closed by sliding in the directions of the arrows in FIGS. 8(a) and 8(b). By sliding the sliding door 1 in the closing direction, which is the left direction in the drawing, the latch portion 70 accommodated in the latch receiving portion 71 is opened at the closed position of the sliding door 1 where the front surface F and the wall W are in contact with each other. Prepare.
As shown in FIG. 8(b), the latch portion 70 includes an arm 75 coupled with a portion of the sliding member 20 and extending in the opening direction of the door opening 77, and an arm 75 coupled with the arm 75 and at least partially formed of a column. A latch 73 having a surface parallel to the surface of the sliding door 1 on the front end side of the sliding door 1 is provided on the door bottom direction side of the column.
In this embodiment, the arm 75 and the sliding body 20 are integrally formed, and as shown in FIG. have the same width, the boundary between the arm 75 and the sliding body 20 is ambiguous. At least the part that is slidably installed in the state of FIG.
As described in the first embodiment, the sliding of the sliding member 20 enlarges the opening/closing operation area 5. Therefore, in order to secure the sliding distance, not only the sliding member 20 but also the arm 75 has a width in the sliding door thickness direction. should be thin.
In this embodiment, the arm 75 connected to the sliding member 20 can move in the thickness direction of the sliding door up to the limit of expansion and contraction of the elastic member or until it contacts the edge of the door opening.

The latch portion 70 includes an arm 75 and a latch 73 connected to the arm. The latch 73 in this embodiment is a columnar body, and the upper surface thereof has a straight edge parallel to the front end surface of the door on the door bottom side in plan view shown in FIG. 8(a). Other edges are curved and convex in the left direction in the figure. Since the latch 73 is connected to the sliding body 20 via the arm 75, it moves in conjunction with the sliding.
In this manner, the latch portion 70 having the arm 75 and the latch 73 is attached to the latch receiving portion 71, which is a cavity provided in the wall W on the left side of FIGS. be accommodated.
The wall W is a wall only when the sliding door 1 is a door.

The latch receiver 71 has a columnar latch receiver 72 in its cavity, as shown in the left-hand diagrams of FIGS. 8(a), (b) and (c). As shown in FIG. 8(a), the latch receiver 72 of this embodiment is line-symmetrical to the latch 73 with respect to a straight line parallel to the door tip surface in plan view. As shown on the left side of FIG. 8(d), the latch receiver 72 can also be provided inside a slip guard that is provided on a general door frame.

A state in which the latch portion 70 is accommodated in the latch receiving portion 71 when the sliding door 1 is closed is a latched state.
When the sliding door 1 is slid in the closing direction to close it, the convex tip of the latch 73 in FIG. 8A contacts the convex tip of the latch receiver 72 . After that, the latch 73 maintains contact with the latch receiver 72 fixed to the latch receiver 71, and expands and contracts the elastic body in either the upper or lower direction from the viewpoint of FIG. drift along. After that, when the latch back surface 79 parallel to the door front surface of the latch 73 and the latch reception back surface 79' parallel to the door front surface of the latch receiver 72 are on the same plane, the elastic body 74 , the latch 73 moves to the center of the thickness of the sliding door while maintaining contact with the latch receiver 72, and the latch rear surface 79 and the latch receiver rear surface 79' overlap each other. The latch is thus applied.

To release the latch means to eliminate the overlap between the latch back surface 79 and the latch receiving back surface 79' that hinder the movement of the sliding door 1 in the opening direction.
From the viewpoint of FIG. 8(a), sliding the sliding body 20 upward causes the arm 75 and the latch 73 connected therewith to move upward, or sliding the sliding body 20 downward causes it to move upward. The connected arm 75 and latch 73 move downward, and the overlap between the latch back surface 79 and the latch receiving back surface 79' disappears, so that the movement of the sliding door 1 in the opening direction is unhindered. In this state, the latch is released by putting a finger or the like on the opening/closing operation area 5 and sliding the sliding door in the opening direction.

As described above, the latch is engaged or unlatched by moving the latch in the horizontal direction from the viewpoint of FIG. 8(d). The latch receiving portion 71 must be wide enough for the latch 73 to enter.
Since the arm 75 and a part of the latch 73 move in the thickness direction of the sliding door to engage the latch, the cavity of the latch receiving portion 71 also has a cavity vertically above the latch receiving portion 72 in order to enable the movement. there is
The reason why the latch 73 and the latch receiver 72 have the shapes as described above in plan view is to ensure smooth contact between the latch 73 and the latch receiver 72 until the latch is engaged. 8(b) where the latch 73 contacts the latch receiver 72 is the portion surrounded by the circular dotted line. There are no restrictions on the shape as long as it can be accommodated in the

There is no limit to the position and number of elastic bodies as long as they can perform the latch function. However, as the surface area of the sliding body 20 parallel to the sliding door surface becomes relatively large, the sliding movement tends to become less smooth. It will be. The position of the elastic body 74 is preferably such that the part of the person performing the sliding operation does not come into contact with the elastic body 74 when the sliding body 20 slides.

Although the latch part 70 protrudes from the sliding door 1 in the exposed state in this embodiment, a cover (not shown) may be provided to protect them. In the cover, the latch 73 operates in the thickness direction of the sliding door, and the cover itself takes such a shape as to be accommodated in the latch receiving portion.
Collision of the latch 73 with the inner surface of the latch receiving portion 71 on the side of the wall W when the latch is engaged leads to failure of the latch mechanism, which is not preferable. Therefore, when the sliding door 1 is closed, the collision of the latch 73 is avoided by adopting a structure in which the front surface F and the wall W first collide, or the cover collides with the inner surface of the latch receiving portion 71 on the wall W side. is preferred.

It is not common for sliding doors to have a latch mechanism. However, if the sliding door does not close completely after many years of use, or if you want to prevent it from moving in the opening and closing direction due to a slight earthquake, it is not necessary to lock it, but it is necessary to operate the sliding body to open and close the sliding door. Therefore, there are not a few merits and needs for providing a latch mechanism for the sliding door, such as when it is desired to prevent an infant from moving over the sliding door 1 .

The latch structure in this embodiment is applicable not only to the sliding door 1 in the first embodiment, but also in the second embodiment as long as the sliding door 1 is provided with the sliding body 20. It is equally applicable in embodiments with sliding bodies that are sized. This is the same in the fifth and sixth embodiments provided with the auxiliary operation section. Since the application method is substantially the same as that of the present embodiment, a description thereof will be omitted.

(9) Ninth Embodiment A ninth embodiment will be described with reference to FIG.
The shapes of the latch 83, the latch receiver 82, and the latch receiver 81 are common to those of the eighth embodiment, and the movement of the latch 83 with respect to the latch receiver 82 for engaging or releasing the latch is also common, so description thereof will be omitted. do.
This embodiment differs from the eighth embodiment in the structure that realizes the movement of the latch 83 in the thickness direction of the sliding door. This is because the present embodiment includes the rotating body 40 instead of the sliding body 20 of the eighth embodiment.

An example structure for moving the latch 83 in the thickness direction of the sliding door in conjunction with the rotation of the rotating body 40 will be described with reference to FIG.
First, the sliding door 1 of this embodiment includes a rotating member 41 that rotatably connects a rotating body 40 to the sliding door 1. A pulley is fixed to one end of the rotating member 41 so that it rotates with rotation. to A gear 87 is rotatably installed at a position on the side of the door that does not interlock with the rotational movement of the rotating body 40, and a pulley 86' is provided above the gear. A belt 84 connects the two pulleys 86, 86'. As a result, the sliding door 1 has one or more gears 87 that rotate together with the rotating body 40 .

The sliding door 1 is provided with a rail groove 89, which is a groove having a length approximately equal to the thickness of the sliding door, on the door tip side of the gear 87, and is provided with a thin plate-like sliding portion 88 so as to fit into the groove. , the sliding portion 88 slides along the rail groove 89 in the thickness direction of the sliding door. The sliding portion 88 is provided with linear teeth in the thickness direction of the sliding door, which mesh with the gear 87 .

Next, the latch section 80 including the latch 83 will be described. As in the eighth embodiment, the latch portion 80 has an arm 85 and connects the latch 83 and the sliding door 1 through the door opening. Specifically, this arm 85 is connected to a sliding portion 88 . Therefore, the arm 85 and the latch 83 move in the thickness direction of the sliding door as the sliding member 88 slides. With the above structure, the latch 83 can be operated in the thickness direction of the sliding door in conjunction with the rotation of the rotating body 40, and the latch can be latched or unlatched.

Also in this embodiment, an elastic body (not shown) is provided as in the eighth embodiment. They are installed on the sliding door 1 so that the center of the rotating body 40 in the direction perpendicular to the sliding door surface, the center of the latch 83, and the center of the latch receiver 82 can be geometrically on the same plane. It is provided so as to achieve the positional relationship (initial position) in the initial state where no force is applied to rotate the rotating body 40 .
Therefore, the elastic body is arranged in the rotating member 44, the sliding part 88, the gear 87, or a part that operates integrally with them, which is related to the rotation of the rotating body 40, and a restoring force acts toward the initial position. is installed as follows. As a result, the latched position is maintained as in the eighth embodiment.
Regarding the installation of the elastic body, for example, a method of installing a coil spring in the rail groove 89, a method of installing a spiral spring in the gear 87, and the like can be considered.

Although this embodiment can be said to be a mode in which a latch structure is provided in the fourth embodiment, the latch structure of this embodiment can also be provided in embodiments in which the rotating body 40 having other shapes, positions, and sizes is provided. is possible. This is the same in the fifth and seventh embodiments provided with the auxiliary operation section.

(10) Tenth Embodiment A tenth embodiment will be described with reference to FIG. The feature of this embodiment is that the sliding door 1 having the sliding body 20 or the rotating body 40 and the latch structure described above has a locking structure.
As described above, in the latch structure of the present invention, the latch is released in conjunction with the operation of the sliding body 20 or the rotating body 40. It has a structure that prevents the release of the latch by stopping it.

As shown in FIGS. 10(a) to 10(f), on the outer peripheral surface of the sliding body 20 or the rotating body 40, there is provided a bar holder 95 which is a recessed cavity. When the bar 92 is fitted here, the sliding motion of the sliding body 20 and the rotating motion of the rotating body 40 are hindered, and the latch portion cannot be pulled out of the latch receiving portion. can no longer be unlocked.

The locking structure of this embodiment includes a knob 91 for switching between an unlocked state in which the bar 92 is removed from the bar holder 95 and a locked state in which the bar 92 is fitted into the bar holder 95 .
As shown in FIGS. 10(c) and 10(d), the movement of the bar 92 when switching between the unlocked state and the locked state may be such that it enters the bar holder 95 by rotating. As shown in FIGS. 10(e) and 10(f), it may enter into the bar holder 95 by linear motion. As shown in FIGS. 10(c) to 10(f), the knob 91 in the present embodiment performs locking and unlocking by means of a knob capable of rotating when the bar 92 rotates, and the bar 92 performs linear motion. In that case, lock/unlock is performed by a knob that can move linearly.

The sliding door 1 according to the present embodiment can also be provided with an elastic body 94. For example, as shown in FIGS. The elastic body 94 can be provided so that the moving body 20 is positioned at the center of the thickness of the sliding door, and furthermore, the bar 92 is positioned to fit into the bar holder 95 in its initial state.

This embodiment may have a cylindrical case with a bar 92 in the center, a knob at one end, and a keyhole at the other end, as shown in FIG. 10(b). The sliding door can be locked from the outside.

As long as the movement of the sliding body 20 or the rotating body 40 is impeded, the positions of the bar 92 and the bar receiver 95 are not limited as long as this is achieved. As shown in FIGS. 10(c) and 10(e), it is not only possible to provide the bar holder 95 at the upper center of the rotating body 40, but also to displace the bar holder 95 from the upper center as shown in FIG. 10(f). You can set it. Furthermore, as shown in FIG. 10(d), a bar holder 95 can be provided on the right side of the rotating body 40 in the figure. Due to the position avoiding the rotating member 41 for rotating the rotating body 40 with respect to the sliding door 1, it is possible to satisfy various design requirements such as design.

Also in the third embodiment, the locking structure in the tenth embodiment can be provided by providing the bar holder 95 on the protruding member 32 itself.

(11) Eleventh Embodiment In the above embodiment, when the portion occupied by the components related to the operation of the sliding door 1 is the operating portion structure 101, the operating portion structure 101 can be applied not only to the sliding door 1 but also to the hinged door. is. Although many combinations of door types and operation unit structures 101 included in the present invention are conceivable, in the present embodiment, the operation unit structure 101 of the present invention is combined with a latch-integrated door in which the latch unit 102 is integrated with the door. An example of the case where the structure 101 is provided is shown. Note that the hinged door is not limited to a door, and includes any door that can be provided with the operation portion structure 101 .
Since the through-hole portion 2, the sliding member 20, and the like, which are the constituent elements of the operation portion structure 101, are all the same as in the first embodiment, common descriptions are omitted.

FIG. 11(a) shows a schematic perspective view of the hinged door in this embodiment. The door 100 has a structure in which the door body 100 is accommodated in the door case 116 and the inner surface of the door case 116 and the door bottom side surface of the door body 100 are connected by an elastic member 111 . The door is connected to an external installation surface such as a wall via hinges. Since the latch portion 102 is housed in a latch receiving portion (not shown) in the closed state, the latch must be released in order to open. To release the latch, the door body 100 is slid toward the bottom of the door, so that the latch portion 102 is pulled out of the latch receiver, and the door 100 can be opened in the direction of P in FIG. An operation portion structure 101 is provided for opening and closing the door 100, specifically, for performing the sliding operation for releasing the latch and opening and closing the door 100 in the P direction or in the direction opposite to the P direction.

In this embodiment, an example in which the door 100 includes the sliding body 20 is shown. The upper view of FIG. 11(c) is a schematic cross-sectional view of the exemplary control structure 101 at line (VII)-(VII) of FIG. 11(a). The drawing on the lower side is a schematic front view of the operation section structure 101 when one door surface is viewed from the front. As shown in this figure, the through-hole portion 2 and the sliding member 20 are circular. 11(a) is one door surface 114, and the opposite side door surface is the other door surface 115. FIG. 11(c) is one door surface. The sliding body 20 is pushed out from the door surface 114 side to the other door surface 115 side, and the opening/closing operation area 5 within the operation portion structure 101 where a part of the body actually comes into contact appears or expands.
With the sliding body 20 on one door surface 114 side, when the opening/closing operation area 5 does not substantially exist from the viewpoint of the operator on the one door surface 114 side, the other door surface 115 of the sliding body 20 is placed. The opening/closing operation area 5 appears by sliding to the side. In other cases, the opening/closing operation area 5 is expanded as long as the sliding body 20 can slide toward the other door surface 115 side.

Another form of this embodiment is shown in FIG.11(b). As shown in the lower part of the figure, the through-hole portion 2 has a circular shape surrounded by the outer dotted line from the viewpoint of the figure. The area between the solid line and the outer dotted line is the first receiver 7 . As shown in the upper part of FIG. 11(b), the sliding body 20 has a shape like a concave lens from the viewpoint of the figure. Also, the shape of the first receiver 7 is different from that shown in FIG. This notch is provided for hooking a finger or the like, and is for facilitating the opening and closing operation of the hinged door 100 . In the form shown in FIG. 1C, the door 100 is opened and closed by hooking the finger on the first receiver 7 or the first receiver 8 . The sliding operation in this embodiment is performed by pushing a part of the opening/closing operation area 5 formed by the through-hole portion 2 and the receivers 7 and 8 toward the door bottom.

This embodiment is an example in which the operation portion structure 101 in the first embodiment is applied to a hinged door 100 . Similarly, it is also possible to apply the operating portion structure 101 including the sliding body 20, the projecting member 32, and the rotating body 40 in the second to fourth embodiments to the door 100. FIG. Although there are differences in the operation bodies such as the sliding body 20, the protruding member 32, and the rotating body 40, they are common in that the operation of the operation body exists to make the opening/closing operation area 5 appear or expand in the operation part structure 101, In that sense, since it is common to the above description, a specific description is omitted.
When the rotating body 40 is used as a substitute for the sliding body 20 in this embodiment, it is not necessary to provide the receivers 7 and 8. Therefore, the door 100 has no part in order to hang a part of the body in the opening/closing direction of the door 100. Also includes In that case, it is possible to provide something equivalent to the receivers 7 and 8, but it is necessary to provide such that the rotation of the rotating body 40 does not collide with the equivalents of the receivers 7 and 8.

As yet another form, it is possible to have a fixed auxiliary operating part 42 as in the fifth embodiment and movable auxiliary operating parts 50, 68 as in the sixth and seventh embodiments.
