[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-176471 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional door structure described above, the door is opened with the handle in an upright position, which may cause the upright handle to hit the wall surface and damage the handle or the wall surface.

[0005] Therefore, the present invention provides a door structure that is resistant to damage and is robust, and a guide tool used in the door structure. [Means for solving the problem]

[0006] The present invention provides a door structure comprising: a wall surface having an opening; a door configured to open and close the opening, the door having a surface facing the wall surface in a fully open state; a connecting portion having a door rotation axis parallel to the surface direction of the wall surface and connecting the door to the wall surface so that the door can rotate about the door rotation axis to open and close the opening; a storage portion recessed into the surface of the door; a handle portion configured to be graspable to open and close the door, the handle portion being provided in the storage portion so as to be switchable between a stored state in which the door is stored in the storage portion and an expanded state in which the door protrudes from the storage portion; and a guide device for guiding the handle portion, wherein the wall surface has a door-facing portion that faces the surface of the door in the fully open state, and the guide device is provided on the door-facing portion of the wall surface and is configured to abut against the handle portion in the expanded state of the door when the opening is open, guiding the handle portion towards the stored state.

[0007] The door structure of the above configuration is provided with the guide device that guides the handle portion in the unfolded state toward the stored state, so even if the door is opened with the handle portion in the unfolded state, the guide device abuts against the handle portion and guides it toward the stored state, thereby preventing the handle portion from hitting the wall surface and damaging the handle portion or the wall surface, and is therefore robust.

[0008] In the present invention, the guide may guide the handle as the door rotates in the fully open direction.

[0009] According to this configuration, the handle portion can be guided by rotating the door in the fully open direction.

[0010] In addition, in the present invention, the handle portion is attached to the storage section via a handle rotation axis whose base end is parallel to the surface of the door, and is configured so that the stored state and the unfolded state are switched by the tip portion rotating around the handle rotation axis, and the guide device may be configured to guide the handle portion to rotate toward the stored state by abutting against the tip portion of the handle portion.

[0011] According to the above configuration, the guide tool abuts against the tip of the handle to guide the handle, so that the handle can be effectively prevented from hitting the wall surface.

[0012] In addition, in the present invention, the guide device may be configured in an inclined shape with a large protrusion that protrudes toward the door relative to the door-facing portion of the wall surface, and a small protrusion that protrudes toward the door, and the handle portion may be guided from the large protrusion side toward the small protrusion side.

[0013] According to the above configuration, the guide is configured to have an inclined shape including the large protrusion and the small protrusion, so that the handle portion is smoothly guided.

[0014] The present invention also provides a guide device for use in the door structure described above. [Effects of the Invention]

[0015] As described above, according to the present invention, the guide device contacts the handle portion and guides it toward the stored state, thereby preventing the handle portion from hitting the wall surface and damaging the handle portion or the wall surface, and providing a robust door structure and a guide device to be used with the door structure.

[0017] The door structure 1 and the guide device 6 according to one embodiment of the present invention will be described below.

[0018] In the following description, the "height direction Y" refers to the vertical direction of the wall body 2, the "width direction X" refers to the horizontal direction of the wall body 2, and the "inside-outside direction Z" refers to the direction between the inside and outside defined by the wall body 2. The height direction Y, the width direction X, and the inside-outside direction Z are perpendicular to each other.

[0019] The door structure 1 is capable of opening and closing an opening O formed in a wall 2 of a structure such as a vehicle or a building by moving a door 3 that closes the opening O. As shown in Fig. 1, the door structure 1 includes the wall 2 that separates the inside from the outside, the door 3 that closes the opening O formed in the wall 2, a connecting part 4 that connects the wall 2 and the door 3, an opening and closing mechanism 5 for opening and closing the door 3, and a guide device 6 that is provided on a wall surface 20 of the wall 2.

[0020] The wall body 2 has a wall surface 20. Here, in this embodiment, the wall body 2 on the side of the vehicle will be described. Therefore, the wall body 2 separates the interior and exterior of the vehicle. Furthermore, the height direction Y of the wall body 2 corresponds to the vertical direction of the vehicle, the width direction X corresponds to the longitudinal direction of the vehicle, and the thickness direction of the wall body 2 corresponds to the inward / outward direction Z of the vehicle. Therefore, the wall body 2 has a wall surface 20 as the exterior surface of the vehicle. This wall surface 20 is a surface that extends in the height direction Y and the width direction X. Therefore, the surface direction of the wall surface 20 refers to the height direction Y and the width direction X.

[0021] An opening O is formed in the wall 2. This opening O is formed so as to penetrate the wall 2 in the inward / outward direction Z. In this embodiment, the opening O has a rectangular shape defined by a width direction X and a height direction Y. As shown in FIG. 1 , the wall 2 includes an upper wall 21 arranged above the opening O, a lower wall 22 arranged below the opening O, and a side wall 23 arranged on either side of the opening O.

[0022] The upper wall 21 has an upper frame portion 211 that defines the upper edge of the opening O. Here, as described above, the opening O penetrates the wall 2 in the inward-outward direction Z. Therefore, as shown in FIGS. 1 and 2, the upper frame portion 211 extends in the width direction X and the inward-outward direction Z. The upper frame portion 211 includes an upper frame main body 212 to which a door mounting portion 40 (described later) is attached, and an upper frame abutment portion (not shown) that abuts against the back surface 31 of the door 3 (described later). The upper frame abutment portion is located inside the upper frame main body 212 and is made of packing so as to fit closely to the back surface 31 of the door 3 (described later) and eliminate any gap between the wall 2 and the door 3.

[0023] As described above, in this embodiment, the opening O is formed in the wall 2 so as to penetrate the wall surface 20 extending in the height direction Y and the width direction X. Therefore, as shown in FIG. 1 , the upper wall 21 of this embodiment includes an upper wall surface 210 extending in the height direction Y and the width direction X as the wall surface 20 above the opening O. Therefore, in this embodiment, the upper frame portion 211 and the upper wall surface 210 are perpendicular to each other. The upper wall surface 210 has a door-facing portion (not numbered) that faces the surface 30 of the door 3 when the door 3, which will be described later, is in a fully open state. That is, in this embodiment, the portion of the upper wall surface 210 that faces the surface 30 of the door 3 in a fully open state is configured as the door-facing portion.

[0024] The lower wall body 22 is disposed spaced apart from the upper wall body 21 in the height direction Y. The lower wall body 22 has a lower frame portion 221 that defines the lower edge of the opening O, and a lower wall surface 220 that extends in the height direction Y and the width direction X below the opening O. As shown in FIGS. 1 and 2 , the lower frame portion 221 extends in the width direction X and the inward-outward direction Z, and faces the upper frame portion 211 at a distance in the height direction Y. The lower frame portion 221 includes a lower frame main body 222 that faces the other end surface 34 of the door 3, which will be described later, and a lower frame abutment portion (not shown) that abuts against the back surface 31 of the door 3, which will be described later. The lower frame abutment portion is disposed inside the lower frame main body 222 and is made of packing so as to fit closely to the back surface 31 of the door 3, which will be described later, eliminating any gaps.

[0025] As shown in FIG. 1, the side wall 23 is disposed on the side of the opening O. This side wall 23 is connected to the upper wall 21 and the lower wall 22. Here, the opening O in this embodiment has a rectangular shape defined by a height direction Y and a width direction X. Therefore, the side wall 23 is disposed on both sides of the opening O in the width direction X (on the left and right sides in FIG. 1). In the following, one of the side wall 23 will be described, and this also applies to the other side wall 23. The side wall 23 includes a side frame portion 231 that defines the side edge of the opening O, and a side wall surface 230 that extends in the height direction Y and the width direction X on the side of the opening O and is continuous with the upper wall surface 210 and the lower wall surface 220. As shown in FIGS. 1 and 3, the side frame portion 231 extends in the height direction Y and the inward / outward direction Z. This side frame portion 231 is connected to the upper frame portion 211 and the lower frame portion 221 in the height direction Y. The side frame portion 231 is spaced apart from and faces the side frame portion 231 of the other side wall body 23 in the width direction X. The side frame portion 231 of this embodiment includes a side frame main body 232 facing a side end surface 32 of the door 3, which will be described later, and a side frame abutment portion that abuts against the back surface 31 of the door 3, which will be described later. The side frame abutment portion is made of packing so as to fit closely to the back surface 31 of the door 3 and eliminate any gaps.

[0026] The door 3 is used to open and close an opening O formed in the wall 2. To this end, the door 3 is attached to the wall 2 via a connecting member 4 (described later) and is switchable between a fully open state in which the opening O is opened and a fully closed state in which the opening O is closed. As shown in FIG. 1 , the door 3 of this embodiment has a rectangular shape in a front view, with a height direction Y and a width direction X defined so as to close the opening O. As shown in FIGS. 1 and 2 , the door 3 is disposed such that its vertical direction is along the height direction Y, its horizontal direction is along the width direction X, and its thickness direction is along the inward / outward direction Z. The door 3 also has a front surface 30 and a back surface 31 disposed on both sides in the thickness direction and extending in the vertical and horizontal directions, two side end surfaces 32 that are horizontal end surfaces, and one end surface 33 and another end surface 34 that are vertical end surfaces.

[0027] The surface 30 is the outer surface in the inward / outward direction Z. The surface 30 has a rectangular shape extending in the height direction Y and the width direction X. As shown in FIGS. 2 and 4 , the surface 30 of this embodiment is aligned with the surface direction of the wall surface 20 when the door 3 is fully closed, and faces the wall surface 20 (specifically, the door-facing portion) when the door 3 is fully open. Here, as shown in FIG. 1 , a region of the surface 30 that includes the center where the vertical center intersects with the horizontal center and extends a certain distance in the vertical and horizontal directions is defined as a central portion 301, and the region other than the central portion 301 is defined as a peripheral portion 304. The surface 30 also has a recess 300 recessed inward in the inward / outward direction Z. A case 500 of the handle mechanism 50, which will be described later, is provided in this recess 300. Therefore, the recess 300 is formed as a rectangular recess extending in the vertical and horizontal directions. In this embodiment, the recess 300 is provided in the central portion 301. Therefore, in the central portion 301 , the region where the recess 300 is formed is defined as an inner peripheral portion 302 , and the other region is defined as an outer peripheral portion 303 .

[0028] The back surface 31 constitutes the inner surface of the door 3 in the inward / outward direction Z. When the door 3 is in a fully closed state covering the opening O, the back surface 31 abuts against the upper frame abutment portion, the lower frame abutment portion, and the side frame abutment portion in the inward / outward direction Z. As shown in FIG. 2, the side end surface 32 is a surface that extends in the inward / outward direction Z and the height direction Y. Therefore, the side end surface 32 is disposed so as to intersect with the front surface 30 and the back surface 31. Furthermore, when the door 3 is in a fully closed state, the side end surface 32 faces the side frame main body 232 in the width direction X. As shown in FIGS. 1 and 2, the one end surface 33 and the other end surface 34 are surfaces that extend in the inward / outward direction Z and the width direction X. The one end surface 33 and the other end surface 34 intersect with the front surface 30 and the back surface 31, as well as with the two side end surfaces 32. When the door 3 is in a fully closed state covering the opening O, one end surface 33 faces the upper frame body 212 and the other end surface 34 faces the lower frame body 222.

[0029] The connecting portion 4 is for connecting the door 3 to the wall body 2 so that the door 3 can rotate relative to the wall body 2. As shown in Fig. 2, the connecting portion 4 is configured as a hinge and includes a door rotation axis 42 parallel to the surface direction of the wall surface 20 (specifically, the width direction X), a wall mounting portion 41 attached to the wall body 2 (specifically, the upper frame main body 212), and a door mounting portion 40 attached to the door 3 (specifically, one end surface 33). In this embodiment, the door 3 and the wall body 2 are connected by four connecting portions 4 (only one connecting portion 4 is marked in Fig. 1).

[0030] The door pivot shaft 42 is a circular shaft member extending along the width direction X. This door pivot shaft 42 serves as the rotation center when the door mounting portion 40, which will be described later, rotates. In this embodiment, the door pivot shaft 42 is disposed further outward in the inward / outward direction Z than the wall surface 20 or the surface 30. The door mounting portion 40 is configured to be rotatable relative to the wall mounting portion 41 attached to the upper frame body 212 via the door pivot shaft 42. Therefore, the door mounting portion 40 rotates relative to the wall mounting portion 41 around the width direction X. Therefore, as shown in FIGS. 2 to 4 , the door 3 to which the door mounting portion 40 is attached can be switched between a fully open state and a fully closed state by rotating around the door pivot shaft 42 relative to the wall body 2 to which the wall mounting portion 41 is attached.

[0031] The connecting portion 4 includes a load mechanism that applies a load against rotation in the closing direction to the door 3 when the door 3 is opened from the fully closed state by more than a predetermined angle. In this embodiment, the door mounting portion 40 rotates around the width direction X relative to the wall mounting portion 41, thereby switching the door 3 between the fully closed state and the fully open state. Assume that the door mounting portion 40 rotates the door 3 from the fully closed state to open it by more than a predetermined angle. Then, the door mounting portion 40 is configured to make it difficult for the door 3 to rotate in the closing direction. That is, the door mounting portion 40 is configured so that a greater force is required to move the door 3 that is opened by more than a predetermined angle in the closing direction than to move the door 3 that is opened by less than a predetermined angle in the closing direction. Therefore, the door mounting portion 40 functions as a load mechanism when the door 3 is opened by more than a predetermined angle from the fully closed state. Therefore, the door 3 that is opened by more than a predetermined angle from the fully closed state is prevented from naturally returning to the fully closed state.

[0032] The opening and closing mechanism 5 is for switching the door 3 from a fully closed state to a state in which the opening O is open. The opening and closing mechanism 5 includes a handle mechanism 50 used to move the door 3, and a lock mechanism 51 that restricts movement of the door 3 in the inward and outward directions Z.

[0033] The handle mechanism 50 is used when moving the door 3 to open the opening O. The handle mechanism 50 is provided on the surface 30 of the door 3. As shown in FIGS. 2 and 3 , the handle mechanism 50 of this embodiment includes a case 500 provided in the recess 300 of the surface 30, and a handle portion 501 and a handle rotation shaft 502 housed in the case 500.

[0034] The case 500 is for accommodating the handle portion 501. The case 500 includes a case body (not numbered) that is configured to have a concave shape by including a bottom plate portion (not numbered) that forms the bottom of the case 500 and side plate portions (not numbered) that rise from the bottom plate portion, and a flange portion (not numbered) that fixes the case 500 to the surface 30 with screws or the like. In this embodiment, the bottom plate portion is disposed within the recess 300 so as to extend vertically and horizontally, and the side plate portions extending vertically and horizontally rise outward from the bottom plate portion, thereby accommodating the case body in the recess 300, and the flange portion is fixed to the surface 30, thereby providing the case 500 with the surface 30. Therefore, the case 500 is provided in the central portion 301 (specifically, the inner peripheral portion 302) and is configured to have a concave shape. In this embodiment, the case 500 is configured as a storage portion 500 recessed into the surface 30.

[0035] As shown in Fig. 3, the handle rotation shaft 502 is an axial member extending in the plane direction of the front surface 30. In this embodiment, the handle rotation shaft 502 extends along the width direction X. Therefore, the handle rotation shaft 502 in this embodiment is arranged parallel to the door rotation shaft 42. This handle rotation shaft 502 extends in the width direction X inside the door 3 so as to penetrate the side panel portion arranged in the horizontal direction and pass through the case 500. This handle rotation shaft 502 is rotatable around the width direction X.

[0036] The handle portion 501 is to be grasped by an operator when moving the door 3 to open the opening O. As shown in FIGS. 1 and 2, the handle portion 501 is housed in the case 500 in a state in which it extends in the height direction Y and the width direction X and has a thickness in the inward / outward direction Z. As shown in FIGS. 2 and 3, the handle portion 501 is configured to be switchable between a stored state in which it is housed in the case 500 and an expanded state in which it protrudes from the case 500. Therefore, as shown in FIG. 2, in this embodiment, when the handle portion 501 is in the stored state, an outer surface 507, which is the outer surface of the handle portion 501, extends in the height direction Y and the width direction X. Note that the thickness of the handle portion 501 in this embodiment is shorter than the length (depth) of the case 500 as the storage section 500 in the inward / outward direction Z, so that the handle portion 501 is completely housed in the case 500 in the stored state.

[0037] As shown in FIG. 3 , the handle portion 501 includes a base end portion 503 through which the handle rotation shaft 502 is inserted, and a tip end portion 504 disposed on the opposite side of the base end portion 503. The handle rotation shaft 502 is inserted into the base end portion 503, preventing the handle portion 501 from coming off the case 500. The base end portion 503 is fixed to the handle rotation shaft 502, so that the handle portion 501 rotates in conjunction with the handle rotation shaft 502. The tip end portion 504 in this embodiment is disposed between the handle rotation shaft 502 and the door rotation shaft 42. Therefore, the tip end portion 504 in this embodiment is disposed above the base end portion 503. The tip end portion 504 can be switched between a state in which it is housed in the case 500 and a state in which it protrudes from the case 500. Specifically, in this embodiment, the tip end portion 504 rotates around the base end portion 503 as a rotation fulcrum, thereby protruding from the case 500. Thus, the handle portion 501 of this embodiment is configured to be switchable between a stored state in which it is stored in the storage unit 500 and an expanded state in which it protrudes from the storage unit 500 by rotating the tip portion 504 about the handle rotation shaft 502. Furthermore, the tip portion 504 of this embodiment abuts against the guide 6, which will be described later, when the door 3 is rotated from the fully closed state to the opening direction while the handle portion 501 is in the expanded state. Furthermore, as shown in FIG. 5 , the tip portion 504 of this embodiment includes a grip portion 505 extending parallel to the handle rotation shaft 502 and spaced apart from the base end portion 503 to form an opening (shown in FIGS. 1 and 5 but not numbered) for an operator to insert their fingers, and a pair of arms 506 connecting the base end portion 503 and the grip portion 505 at both ends in the width direction X, forming a U-shape. Therefore, for example, an operator can grasp the handle portion 501 by gripping the grip portion 505.

[0038] As described above, the door 3 rotates around the door rotation shaft 42 relative to the wall body 2. Therefore, for example, wind pressure may cause the door 3, which is in a fully closed state, to rotate unintentionally to a state in which the opening O is open. To prevent such unintentional rotation, the locking mechanism 51 is provided. As shown in FIGS. 2 and 3 , the locking mechanism 51 includes an engaging portion 510 and an engaged portion 511 that engage with each other. That is, when the door 3 is in a fully closed state, the engaging portion 510 and the engaged portion 511 engage with each other, so that the locking mechanism 51 prevents the door 3 from switching from the fully closed state to a state in which the opening O is open.

[0039] In this embodiment, the engaging portion 510 is configured as a hook 510, and the engaged portion 511 is configured as a hook groove 511 that can accommodate the hook 510. The engaging portion 510 engages with the engaged portion 511 as the hooks 510 and 511 abut against each other when the hooks 510 are accommodated in the hook grooves 511. Furthermore, the engaging portion 510 in this embodiment is configured to rotate as the handle portion 501 switches between the stored state and the deployed state. Specifically, in this embodiment, the engaging portion 510 is provided on the side end surface 32, the engaged portion 511 is provided on the side frame main body 232, and the engaging portion 510 is configured to rotate as the handle rotation shaft 502 rotates. 2 and 3, in this embodiment, when the handle portion 501 is switched from the stored state to the deployed state in order to open the opening O, the engaging portion 510 and the engaged portion 511 are switched to disengage, and the hook 510 serving as the engaging portion 510 rotates to come out of the hook groove 511. This allows the door 3 to be switched from a fully closed state to a state in which the opening O is opened. In this embodiment, the hook 510 rotates inward in the inward / outward direction Z while abutting against the hook groove 511, and the hook 510 moves to come out of the hook groove 511 due to the resistance from the hook groove 511, and the door 3 rotates in a direction in which the opening O is opened.

[0040] The guide 6 is for guiding the handle 501 from the unfolded state to the stored state. The guide 6 is provided at the door-facing portion. Here, the guide 6 of this embodiment includes a guide main body 60 that abuts against the handle 501, and a guide mounting portion 61 for mounting the guide main body 60 to the door-facing portion.

[0041] As shown in FIGS. 4(a) and 4(b), the guide body 60 contacts the tip 504 to guide the handle 501 from the unfolded state toward the stowed state. The guide body 60 is a plate-like body extending in the height direction Y and the width direction X, and is provided so as to protrude outward from the door-facing portion. As shown in FIG. 4(a), the guide body 60 protrudes from the door-facing portion so as to contact the tip 504 of the handle 501 of the door 3 when the door 3 is opened from the fully closed state to an angle smaller than the predetermined angle. The guide body 60 is configured to guide the handle 501 toward the stowed state as the door 3 rotates from the angle of the door 3 at which the tip 504 of the handle 501 contacts the guide body 60 to the fully open state shown in FIG. 4(b). Furthermore, the length of the guide body 60 in the height direction Y is set so as to guide the handle 501 from the unfolded state to a position immediately before switching to the stowed state in the unfolded state. Specifically, as shown in FIGS. 4(a) and 4(b), the guide body 60 has a length that allows the tip 504 of the handle portion 501 in the unfolded state to continue to abut against the guide body 60 from the angle of the door 3 at which the tip 504 of the handle portion 501 in the unfolded state abuts against the guide body 60 to the angle at which the door 3 is fully opened. The position immediately before the handle portion 501 in the unfolded state is switched to the storage state refers to the rotation position of the handle portion 501 at the angle at which the door 3 is fully opened. As shown in FIGS. 2 to 4, the guide body 60 of this embodiment includes a large protrusion 600 protruding from the door-facing portion, a small protrusion 601 having a smaller protrusion width than the large protrusion 600, and a guide surface 602 formed across the large protrusion 600 and the small protrusion 601, and is configured in an inclined shape. The guide body 60 is disposed in the door-facing portion at a position where it abuts against the handle portion 501 in the rotation direction when the door 3 is rotated to open the opening O. Furthermore, the guide body 60 is arranged in the door facing portion so as to face the handle portion 501 with the door facing portion and the surface 30 of the door 3 facing each other. As shown in FIG. 1, the guide body 60 of this embodiment is arranged above the center portion 301 in the height direction Y of the door facing portion, and specifically, at least a part of the guide body 60 in the width direction X is arranged above the inner peripheral portion 302 in the height direction Y of the door facing portion. Therefore, as shown in FIG. 5, the guide body 60 is configured to be able to abut against a part of the width direction X of the handle portion 501.

[0042] 2 to 4, the guide body 60 of this embodiment is configured in a tapered shape such that the protruding width from the door opposing portion decreases from the side farther from the door rotation shaft 42 to the side closer to the door rotation shaft 42 in the height direction Y. Therefore, the large protrusion 600 is disposed higher in the height direction Y than the small protrusion 601. Also, as shown in FIG. 5, the guide surface 602 abuts against the tip 504 of the handle portion 501. This guide surface 602 is configured as a tapered surface whose distance from the door opposing portion in the inward / outward direction Z decreases as it approaches the door rotation shaft 42 in the height direction Y.

[0043] 1, the guide mounting portions 61 are used to mount the guide body 60 on the wall surface 20. The guide mounting portions 61 of this embodiment are disposed at both ends of the guide body 60 in the width direction X, and mount the guide body 60 on the wall surface 20 by screws.

[0044] Next, the operation of the door structure 1 of this embodiment will be described. Here, a case where the door structure 1 is switched from a fully closed state to a fully open state will be described. When the door structure 1 is switched from a fully closed state to a fully open state, as shown in FIGS. 2 and 3 , first, a user places a finger through the finger insertion opening to grasp the grip portion 505, and then rotates the tip portion 504 around the base end 503 as a rotation fulcrum, thereby causing the tip portion 504 to protrude from the case 500 and switching the handle portion 501 from the stored state to the deployed state. At this time, as the handle rotation shaft 502, which rotates in conjunction with the base end 503, rotates, the hook 510 serving as the engaging portion 510 rotates inward in the inward / outward direction Z while abutting against the hook groove 511 serving as the engaged portion 511. As a result, the hook 510 moves to come out of the hook groove 511 due to the resistance from the hook groove 511, and the door 3 rotates in the direction in which the opening O opens. Next, by applying a force to move the handle portion 501 outward in the inward / outward direction Z and toward the upper wall body 21 in the height direction Y, the door mounting portion 40 rotates around the door rotation shaft 42. Therefore, in the door 3, the one end surface 33 side serves as a rotation fulcrum, and the other end surface 34 side rotates. Therefore, the door 3 rotates around the width direction X and moves in the height direction Y, rotating in a direction to become fully open (fully open direction).

[0045] When the door 3 is rotated from the fully closed state to the opening direction with the handle portion 501 in the unfolded state, as shown in FIG. 4(a), the tip portion 504 of the handle portion 501 of the door 3 opened at an angle smaller than the predetermined angle abuts against the guide surface 602 of the large protrusion 600 of the guide body 60. At this time, as shown in FIG. 5, the guide body 60 of this embodiment abuts against a part of the tip portion 504 of the handle portion 501 in the width direction X. Then, when the door 3 is rotated from the angle of the door 3 at which the tip portion 504 of the handle portion 501 abuts against the guide body 60 to the fully open state, the tip portion 504 is guided from the large protrusion 600 toward the small protrusion 601, thereby guiding the unfolded handle portion 501 in the direction toward the storage state. As shown in FIG. 48(b), when the door 3 is fully opened, the handle portion 501 is guided to a position immediately before switching to the storage state in the unfolded state. Furthermore, when the door 3 is in the fully open state, the surface 30 of the door 3 faces the opposing portion of the door 3 as the upper wall surface 210 in the inward / outward direction Z. In addition, by bringing the door 3 into the fully open state so that the handle portion 501 is guided to a position immediately before switching to the storage state, the connecting portion 4 as a load mechanism applies a load against rotation in the closing direction to the door 3 that is in a state where it is opened more than a predetermined angle, and the door 3 stops without rotating in the closing direction.

[0046] As described above, the door structure 1 of this embodiment is provided with a guide device 6 that guides the handle portion 501 in the unfolded state toward the stored state. Therefore, even if the door 3 is opened with the handle portion 501 in the unfolded state, the guide device 6 abuts against the handle portion 501 and guides it toward the stored state, thereby preventing the handle portion 501 from hitting the wall surface 20 and damaging the handle portion 501 or the wall surface 20, and is robust.

[0047] In this embodiment, the handle portion 501 can be guided by rotating the door 3 in the fully open direction.

[0048] Furthermore, according to this embodiment, the guide 6 contacts the tip 504 of the handle 501 to guide the handle 501, so that the handle 501 can be effectively prevented from contacting the wall surface 20.

[0049] Furthermore, according to this embodiment, the guide body 60 is configured in an inclined shape including the large protrusion 600 and the small protrusion 601, so that the handle portion 501 is smoothly guided. Specifically, in this embodiment, when the door 3 is rotated so that the surface 30 of the door 3 approaches the door opposing portion, the tip portion 504 of the handle portion 501 is guided by the guide surface 602, which is a tapered surface, and rotates to move from the large protrusion 600 side to the small protrusion 601 side, so that the handle portion 501 in the unfolded state can be guided toward the stored state.

[0050] In this embodiment, the guide 6 guides the handle 501 to a position immediately before switching from the unfolded state to the stored state. Therefore, when the door 3 is subsequently switched to the closed state to close the opening O, the handle 501 can be easily grasped.

[0051] In addition, in this embodiment, the handle rotation axis 502 is provided parallel to the door rotation axis 42, the handle portion 501 is arranged so that its tip portion 504 is located between the handle rotation axis 502 and the door rotation axis 42, and the guide device 6 guides the handle portion 501 as the door 3 rotates in the fully open direction, so that it is easy to grasp the handle portion 501 and rotate the door 3, and the guidance as the door 3 rotates is also smooth.

[0052] Furthermore, in this embodiment, the connecting portion 4 has a load mechanism that applies a load to the door 3 that is open more than a predetermined angle, resisting rotation in the closing direction, and the guide device 6 abuts against the handle portion 501 of the door 3 that is open to an angle smaller than the predetermined angle, and guides the handle portion 501 as the door 3 rotates until it opens to more than the predetermined angle, so that the door 3 can be reliably opened to more than the predetermined angle at which the load mechanism operates.

[0053] In addition, in this embodiment, since the guide 6 is disposed at a position where the handle 501 comes into contact, by bringing the handle 501 into contact with the guide 6, it is possible to prevent the wall surface 20 from being damaged by the handle 501.

[0054] Furthermore, in this embodiment, the guide body 60 is arranged such that a portion of the width direction X faces the handle portion 501, and therefore a portion of the tip portion 504 of the handle portion 501 in the width direction X abuts against the guide surface 602 and is guided. As a result, the area of ​​contact between the guide tool 6 and the handle portion 501 is small, and it is easy to guide the handle portion 501 in the unfolded state toward the stored state.

[0055] The door structure 1 and guide device 6 of the present invention are not limited to the above-described embodiment, and can be modified as appropriate within the scope of the invention.

[0056] In the above embodiment, the door structure 1 has been described assuming that the door structure 1 is a wall 2 on the side of a vehicle, but the door structure 1 is not limited to this and may be a wall 2 other than a vehicle wall, for example, a wall 2 that separates the inside and outside of a building, or a wall 2 installed inside a building. The wall 2 may also be a wall that separates a space in the height direction, such as a ceiling or floor. The opening O is not limited to a rectangular shape and may be, for example, a triangular or circular shape.

[0057] In the above embodiment, the door 3 is described as being rotated from bottom to top around the door rotation shaft 42 extending in the width direction X, but this is not limiting, and the door 3 may be configured to be rotated from top to bottom, right to left, or left to right. In this case, the arrangement of the door opposing parts and the extending direction of the door rotation shaft 42 parallel to the surface direction of the wall surface 20 may be changed according to the direction in which the door 3 is desired to be rotated.

[0058] In the above embodiment, the case where the guide device 6 guides the handle portion 501 in the unfolded state to a position just before the stored state in the unfolded state has been described, but this is not limited to this. For example, the guide device 6 may be configured to guide the handle portion 501 in the unfolded state to the stored state.

[0059] In the above embodiment, the handle portion 501 could be switched between a stored state and an unfolded state by rotating the tip portion 504 around the handle rotation axis 502, but the handle portion 501 may also be configured to switch between a stored state and an unfolded state by sliding inward and outward in the Z direction from the storage portion 500, for example.

[0060] In the above embodiment, the guide body 60 is configured in a tapered shape in which the protruding width from the door-facing portion of the wall surface 20 decreases from the side farther from the door rotation shaft 42 toward the side closer to the door rotation shaft 42, but this is not limiting, and the guide body 60 may be configured in a tapered shape in which the protruding width from the door-facing portion of the wall surface 20 increases from the side farther from the door rotation shaft 42 toward the side closer to the door rotation shaft 42. In this case, it is considered that the handle portion 501 is stored in the storage portion 500 so that the base end portion 503, through which the handle rotation shaft 502 is inserted, is positioned between the door rotation shaft 42 and the tip portion 504.

[0061] In the above embodiment, the handle portion 501 in the stored state is configured to be flush with the wall surface 20, but this is not limited to this. For example, the handle portion 501 in the stored state may not be flush with the wall surface 20, but may protrude outward from the wall surface 20 in the inward / outward direction Z, or may be positioned inward from the wall surface 20.

[0062] In the above embodiment, a case has been described in which the hook 510 as the engaging portion 510 rotates and comes out of the hook groove 511 as the engaged portion 511 in conjunction with the handle portion 501 switching from the stored state to the deployed state, but this is not limited to this, and for example, the hook 510 as the engaging portion 510 does not have to rotate and come out of the hook groove 511 as the engaged portion 511 in conjunction with the switching.

[0063] In the above embodiment, the door 3 rotates in the height direction Y, and the handle portion 501 also rotates in the height direction Y. However, for example, the door 3 may rotate in the height direction Y, and the handle portion 501 may rotate in the width direction X.

[0064] In the above embodiment, the door mounting part 40 as a loading mechanism is configured to make it difficult for the door 3 to rotate in the closing direction when the door 3 in the fully closed state is rotated to open more than a predetermined angle. However, this is not limiting, and for example, the door mounting part 40 as a loading mechanism may be configured to restrict the door 3 from rotating in the closing direction when the door 3 in the fully closed state is rotated to open more than a predetermined angle.

[0065] In the above embodiment, the engaging portion 510 is configured as the hook 510, the engaged portion 511 is configured as the hook groove 511 capable of accommodating the hook 510, and the engaging portion 510 engages with the engaged portion 511 by abutting against each other with the hook 510 accommodated in the hook groove 511. However, without being limited to this, for example, a latch bolt as the engaging portion 510 may be engaged with a latch as the engaged portion 511.

[0066] In the above embodiment, the case has been described in which the upper wall surface 210 extending in the height direction Y and the width direction X as the wall surface 20 above the opening O has a door facing portion facing the surface 30 of the door 3, but this is not limiting, and for example, the door facing portion may be a surface extending in the width direction X and the inward / outward direction Z. In other words, it is sufficient that the door facing portion is disposed in a position facing the surface 30 of the door 3 that rotates from the fully closed state.

[0067] In the above embodiment, the case 500 is described as the storage section 500, but for example, if the handle mechanism 50 does not have the case 500 and the handle section 501 is provided in the recess 300, the recess 300 is configured as the storage section.

[0068] In the above embodiment, the recess 300 is provided in the central portion 301. However, for example, the recess 300 may be provided in the peripheral portion 304. In this case, it is considered that the guide body 60 is also provided in the peripheral portion 304.

[0069] In the above embodiment, the case where the handle rotation shaft 502 is arranged parallel to the door rotation shaft 42 has been described, but the present invention is not limited to this, and for example, the handle rotation shaft 502 may be arranged in the height direction Y that intersects with the door rotation shaft 42 that extends in the width direction X. In this case, it is considered that the arrangement of the guide 6 is appropriately changed in accordance with the direction in which the handle portion 501 rotates so that the guide 6 can guide the handle portion 501.

[0070] In the above embodiment, the case where the tip portion 504 is disposed between the handle rotation shaft 502 and the door rotation shaft 42 has been described, but this is not limiting, and for example, the tip portion 504 may be disposed lower in the height direction Y than the handle rotation shaft 502 and the door rotation shaft 42. In this case, it is considered that the position of the guide tool 6 is appropriately changed in accordance with the direction in which the handle portion 501 rotates so that the guide tool 6 can guide the handle portion 501.

[0071] In the above embodiment, the case where the tip portion 504 abuts against the guide device 6 when the door 3 is rotated from the fully closed state to the opening direction while the handle portion 501 is in the expanded state has been described, but for example, the outer surface 507 may be configured to abut against the guide device 6.

[0072] In the above embodiment, the case where the guide body 60 is inclined has been described, but the guide body 60 is not limited to an inclined shape as long as it can guide the handle portion 501 toward the storage state, and may be, for example, a shape extending along the height direction or a curved shape.

[0073] In the above embodiment, the handle portion 501 is configured to be guided from the large protrusion 600 to the small protrusion 601, but this is not limited to this. For example, the handle portion 501 in the unfolded state may be guided toward the stored state by guiding it from the small protrusion 601 to the large protrusion 600. [Explanation of symbols]
