It is installed in a position where it does not. The reason for setting such an installation position is as shown below. That is, when the rotation center position C of the hinge portion is positioned on the center line, the door body 20 tends to be in constant contact with the edge portion 16a regardless of the rotation state of the door body 20. This is to avoid the possibility that the wear of the edge portion 16a is promoted due to such a contact state and the resistance due to the edge portion 16a is increased when the door body 20 is rotated.

(Structure-Details of door body configuration-Finger pinch prevention part)
Further, as shown in FIGS. 3 to 5, a finger pinching prevention portion 80 is provided on a portion of the outer side surface of the target space 5 in the door body 20 on the door tail side. The finger pinching prevention unit 80 is a finger for preventing the user's finger from being caught in the gap between the door tail side vertical frame 11 and the finger pinching prevention unit 80 regardless of the rotational state of the door body 20. It is a scissors prevention means. Here, regarding the size of the gap between the door tail side vertical frame 11 and the finger pinching prevention portion 80, specifically, the user's finger is always inserted regardless of the rotating state of the door body 20. It is set to be about an impossible size or less (for example, the size of the gap is 7 mm or less at the maximum). Further, the finger pinching prevention portion 80 is made of, for example, an aluminum material, a steel material, a stainless steel material, a resin material, or the like, and is doord by a fixture (for example, a screw, a clip, a cap, etc.) or a double-sided tape. It is attached to the body 20. The specific shape of the finger pinching prevention unit 80 is arbitrary, but in the embodiment, as shown in FIGS. 4 and 5, the length (width) of the finger pinching prevention unit 80 in the left-right direction. Is formed to be shorter than the length (width) of the door body 20 in the left-right direction, and the length (height) of the finger pinching prevention portion 80 in the vertical direction is the length of the door body 20 in the vertical direction. It is formed so as to be substantially the same as (or shorter) the length (height).

(Structure-Details of the structure of the door body-Finger pinching prevention part-Details of the structure of the finger pinching prevention part-First feature)
Next, the details of the configuration of the finger scissors prevention unit 80 will be described. First, regarding the first feature of the configuration of the finger scissors prevention unit 80, as shown in FIGS. 4 to 6, the planar shape of the finger scissors prevention unit 80 (the shape when viewed from above the finger scissors prevention unit 80). However, regardless of the rotational state of the door body 20, the finger pinching prevention portion 80 has a polygonal line shape that can prevent the finger pinching prevention portion 80 from coming into contact with the door tail side vertical frame 11, and has a polygonal line shape having at least two or more bent portions. It is formed. Here, the "line shape" means a side portion forming a bent portion, and means a shape consisting of only a linearly formed side portion. The reason why the plane shape of the finger scissors prevention portion 80 is the above-mentioned broken line shape is that, for example, when the plane shape of the finger scissors prevention portion 80 is a curved shape including an arc-shaped portion, FIGS. As shown in 4, the peripheral members of the finger pinching prevention portion 80 (for example, the door body 20, the vertical frame 11 on the door tail side, etc., hereinafter referred to as “peripheral members”) are designed to have a planar shape centered on a straight line. Therefore, it is difficult to maintain the uniformity of the shapes of the finger pinching prevention portion 80 and the peripheral member regardless of the rotational state of the door body 20, so that the finger pinching prevention portion 80 and the peripheral member are separated from each other. This is to avoid such a problem because it becomes difficult to harmonize the designs.

Specifically, as shown in FIGS. 4 to 5, the finger pinch prevention portion 80 is located on the door tail side bent portion 81, which is located closest to the door tail side in the fully closed state, and on the door end side most in the fully closed state. It is formed in a polygonal line shape having a bent portion 82 on the door end side where it is located. More specifically, the door butt is located most on the door butt side in the fully closed state (in FIG. 4, it is located so as to reach the door butt side bending portion 81 from the end of the finger pinching prevention portion 80 on the door butt side). The side portion 83 and the door end located closest to the door end side in the fully closed state (in FIG. 4, the finger pinching prevention portion 80 is located so as to reach the door end side bent portion 82 from the end portion on the door end side). It has a bent line shape consisting of a side side portion 84 and an intermediate side portion 85 extending from the door tail side bent portion 81 to the door end side bent portion 82, and has a door tail between the door tail side side portion 83 and the intermediate side portion 85. The side bent portion 81 is located, and is formed in a bent line shape in which the door end side bent portion 82 is located between the door end side side portion 84 and the intermediate side portion 85. Further, regarding the details of the installation positions of the door tail side side portion 83, the door end side side portion 84, and the intermediate side portion 85, specifically, as shown in FIG. 4, the door body 20 is in the rotated state. Regardless, it is installed so as to be located in a region T (hereinafter, referred to as "installation region T") formed between the first virtual line L1 and the second virtual line L2. Here, the "first virtual line L1" is a virtual line indicating a setting range of the shape of the finger pinching prevention portion 80, and regardless of the rotational state of the door body 20, the finger pinching prevention portion 80 and the door tail side. It is a virtual line indicating a range having the maximum shape that does not come into contact with the vertical frame 11. Further, the "second virtual line L2" is a virtual line indicating a setting range of the shape of the finger pinching prevention portion 80, and the fingers are pinched in the door tail side vertical frame 11 regardless of the rotating state of the door body 20. A virtual line indicating the range of the shape in which the distance between the portion for which the user wants to avoid (in the embodiment, the tip portion 74a of the mating portion 74) and the finger pinching prevention portion 80 is the maximum distance during which the user's finger cannot be inserted. Is.

Further, the method of installing the door end side bent portion 81 and the door end side bent portion 82 is arbitrary, but in the embodiment, as shown in FIG. 4, the rotation center position of the door end side bent portion 82 and the hinge portion. The distance X1 in the finding direction (horizontal direction) between C and the other (hereinafter referred to as "first distance X1") is the finding direction (horizontal direction) between the hinge side bending portion 81 and the rotation center position C. ) Is less than or equal to the distance X2 (hereinafter referred to as "second distance X2"). Specifically, the first distance X1 is lower than the second distance X2, and the door tail side bent portion 81 and the door end side bent portion 82 are located between the first virtual line L1 and the second virtual line L2. It is installed so as to be located on the substantially third virtual line L3. Here, the "third virtual line L3" is the end on the door end side of the outer side surface end of the target space 5 of the door body 20 in the locus of the door body 20 accompanying the rotation of the door body 20. It is a virtual line which shows the locus of part 21. The reason why the first distance X1 is set to the second distance X2 or less is as shown below. That is, when the first distance X1 exceeds the second distance X2 as shown in FIG. 7, it is fully opened as compared with the case where the first distance X1 is set to the second distance X2 or less as shown in FIGS. 4 and 6. Since the gap S2 (see FIGS. 6 (c) and 7 (b)) between the finger pinching prevention portion 80 and the tip portion 74a of the mating portion 74 becomes smaller in the non-fully opened / closed state closer to the state, the finger scissors are pinched. The finger pinching prevention unit 80 may come into contact with the mating portion 74 due to the influence of the manufacturing accuracy of the prevention portion 80 or the door tail side vertical frame 11 (particularly, the mating portion 74) (for example, the influence of distortion, distortion, etc. of the member). This is to avoid this and maintain the usability of the door 1. The reason why the bent portion 81 on the door tail side is positioned on the substantially third virtual line L3 is as shown below. That is, when the door tail side bent portion 81 is positioned in the vicinity of the substantially first virtual line L2, the door tail side bent portion 81 is fully closed as compared with the case where the door tail side bent portion 81 is positioned on the substantially third virtual line L3. In a non-fully opened / closed state close to the state, the gap S1 (see FIG. 6B) between the finger pinching prevention portion 80 and the tip portion 74a becomes large, so that the finger may be caught in the gap S1. This is to avoid this and further secure the safety of the door 1.

Further, the specific configuration of the door tail side side portion 83 and the door end side side portion 84 is arbitrary, but in the embodiment, as shown in FIG. 4, the door body 20 of the door end side side portion 84 is provided. Formed so that the inclination angle α1 (hereinafter referred to as “first inclination angle α1”) is equal to or less than the inclination angle α2 (hereinafter referred to as “second inclination angle α2”) with respect to the door body 20 of the door tail side side portion 83. Has been done. Specifically, the distance X3 in the finding direction (left-right direction) between the end portion of the finger pinch prevention portion 80 on the door end side and the bent portion 82 on the door end side (hereinafter referred to as "third distance X3"). However, it is longer than the distance X4 (hereinafter referred to as "fourth distance X4") in the finding direction (left-right direction) between the end of the finger pinch prevention portion 80 on the door tail side and the bent portion 81 on the door tail side. It is formed to be. Here, the reason why the first inclination angle α1 is set to the second inclination angle α2 or less is as shown below. That is, when the first inclination angle α1 is made larger than the second inclination angle α2 as shown in FIG. 8, the first inclination angle α1 is set to be equal to or less than the second inclination angle α2 as shown in FIGS. 4 and 6. Compared to the case, in the non-fully opened / closed state close to the fully opened state, the gap S3 between the finger pinching prevention portion 80 and the tip portion 74a of the mating portion 74 (see FIGS. 6 (d) and 8 (b)) Since it becomes large, there is a possibility that a finger may be caught in the gap S3, and this is to avoid this and further secure the safety of the door 1.

The specific configuration of the intermediate side portion 85 is arbitrary, but in the embodiment, as shown in FIG. 4, the intermediate side portion 85 is substantially along the finding direction (left-right direction) in the fully closed state. It is formed. Specifically, in the fully closed state, the distance between the door tail side bent portion 81 and the door end side bent portion 82 in the finding direction (left-right direction) (that is, the sum of the first distance X1 and the second distance X2). The distance) is formed to be longer than either the third distance X3 or the fourth distance X4. As a result, the shape uniformity between the finger pinching prevention portion 80 and the peripheral members in the fully closed state can be maintained as compared with the case where the intermediate side portion 85 does not substantially follow the finding direction (left-right direction) in the fully closed state. Therefore, it becomes easy to harmonize the design of the finger pinching prevention portion 80 and the peripheral members.

According to such a first feature, the user's finger is prevented from being caught in the gap between the finger pinching prevention portion 80 and the door tail side vertical frame 11 regardless of the rotating state of the door body 20. Moreover, while maintaining the usability of the door 1, the uniformity of the shape between the finger pinching prevention portion 80 and the peripheral members is maintained as compared with the case where the plane shape of the finger pinching prevention portion 80 is a curved shape including the arcuate portion. can do. Therefore, the design of the finger pinching prevention portion 80 and the peripheral members can be easily harmonized, and the design of the door 1 can be maintained.

(Structure-Details of door body configuration-Finger scissors prevention part-Details of finger scissors prevention part configuration-Second feature)
Next, regarding the second feature of the configuration of the finger pinching prevention portion 80, as shown in FIG. 4, the finger pinching prevention portion 80 protrudes outside the target space 5 from the door tail side vertical frame 11 in the fully closed state. The finger pinching prevention portion 80 is formed so as not to prevent the finger pinching. Here, the reason why the finger pinching prevention portion 80 is formed so as not to protrude outside the target space 5 from the door tail side vertical frame 11 is as shown below. That is, when the finger pinching prevention portion 80 is formed to protrude outside the target space 5 from the door tail side vertical frame 11 in the fully closed state, the finger pinching prevention portion 80 is formed from the peripheral member from the outside of the target space 5. This is to avoid this because it becomes more noticeable.

Specifically, as described above, the finger pinch prevention portion 80 has a polygonal line shape having a door tail side bending portion 81 and a door end side bending portion 82, and has a door tail side side portion 83 and a door end side side portion. It has a polygonal line shape consisting of 84 and the intermediate side portion 85, and the door tail side bending portion 81 is located between the door tail side side portion 83 and the intermediate side portion 85, and the door end side side portion 84 and the intermediate side portion are located. It is formed in a polygonal line shape in which the bent portion 82 on the door end side is located between it and the 85. Further, the details of the installation positions of the door tail side side portion 83, the door end side side portion 84, and the intermediate side portion 85 are specifically, as shown in FIG. 4, the positions in the above-mentioned installation area T. In addition, the intermediate side portion 85 is installed at a position where the intermediate side portion 85 does not protrude outside the target space 5 from the door tail side vertical frame 11 in the fully closed state.

The specific configuration of the finger scissors prevention unit 80 is arbitrary, but in the embodiment, it is configured as shown below. First, in the fully closed state, as shown in FIG. 4, the door tail side bent portion 81 and the door tip side bent portion 82 are formed in a polygonal line shape that is substantially flush with each other along the finding direction (left-right direction). ing. Specifically, in the fully closed state, the position is approximately on the third virtual line L3, and the distance X5 (hereinafter, the front-rear direction) between the door tail side bent portion 81 and the door body 20 in the expected direction (front-rear direction). , "Fifth distance X5") and the distance X6 (hereinafter referred to as "sixth distance X6") in the prospective direction (front-back direction) between the door end side bent portion 82 and the door body 20 are the same. It is formed in a bent line shape in which the door tail side bent portion 81 and the door tip side bent portion 82 are located at such positions. As a result, the finger pinching prevention portion 80 and the peripheral members are compared with the case where the door tail side bending portion 81 and the door tip side bending portion 82 are not substantially flush with each other along the finding direction (left-right direction) in the fully closed state. Since it becomes easy to harmonize the design with the door 1, it is possible to maintain the design of the door 1 in the fully closed state.

Further, as shown in FIG. 4, in the fully closed state, the end portion of the finger pinch prevention portion 80 on the door tail side and the end portion of the door tail side vertical frame 11 on the door end side (in the embodiment, the mating portion 74). The tip portion 74a) is formed so as to be substantially flush with each other along the prospective direction (front-back direction). Specifically, in the fully closed state, the end portion of the finger pinch prevention portion 80 on the door tail side and the tip portion 74a of the mating portion 74 are the end portion of the door body 20 on the door tail side and the prospective direction (front-back direction). It is formed so as to be substantially flush with each other. As a result, other members (for example, the first airtight portion 16 and the like) can be seen from the outside of the target space 5 through the gap between the finger pinching prevention portion 80 and the door tail side vertical frame 11 in the fully closed state. Therefore, it is possible to further maintain the design of the door 1 in the fully closed state.

According to such a second feature, the finger pinching prevention portion 80 is conspicuous as compared with the case where the finger pinching prevention portion 80 is projected to the outside of the target space 5 from the door tail side vertical frame 11 in the fully closed state. Since it disappears, it is possible to maintain the design of the door 1 in the fully closed state.

It is arranged so as to protrude and is connected to the finger pinching prevention unit 80. The specific shape of the cover portion 86 is arbitrary, but in the embodiment, as shown in FIGS. 6 (b) to 6 (d), the cover portion 86 is in either the fully open state or the non-fully opened / closed state. The cover portion 86 is formed in a shape so as not to come into contact with the first airtight portion 16 provided on the door tail side vertical frame 11. Specifically, the length (depth) of the cover portion 86 in the front-rear direction is shorter than the length (depth) and length of the door body 20 in the front-rear direction (more specifically, the length of the door body 20 in the front-rear direction). It is formed so as to be shorter than half of the length, and the vertical length (height) of the cover portion 86 is shorter (or substantially the same) than the vertical length (height) of the door body 20. ) Is formed. As a result, the first airtight portion 16 is rolled up by the contact between the cover portion 86 and the first airtight portion 16 provided on the door tail side vertical frame 11 in either the fully opened state or the non-fully opened / closed state. Since it can be suppressed, it is possible to avoid a decrease in airtightness between the door end side vertical frame 13 and the door body 20 in the fully closed state. Since it is possible to prevent water or the like from entering the inside of the door body 20 through the butt portion 90 by such a cover portion 86, a member arranged inside the door body 20 (for example, a door frame 30 or the like). Can be suppressed from rusting.

Further, the mounting hole 87 is for inserting a fixing tool (for example, a screw or the like) for mounting the finger pinching prevention portion 80 and the cover portion 86 to the door body 20 (specifically, the door tail side longitudinal force bone 31). This is a through hole, and a plurality of holes are arranged side by side in the cover portion 86 along the vertical direction. Further, the first fitting portion 88 is for fitting a fixture (for example, a molding clip or the like), and is vertically along the door end side side portion 84 and the intermediate side portion 85 of the finger pinching prevention portion 80. Multiple units are installed side by side. Further, the second fitting portion 89 is for fitting a fixture (for example, a cap or the like), and at least one or more is provided on the door tail side side portion 83 of the finger pinching prevention portion 80. With these mounting holes 87, the first fitting portion 88, and the second fitting portion 89, the fixture can be easily attached to the finger pinching prevention portion 80 or the door body 20, and the finger pinching prevention portion 80 can be attached.

(Door action)
Subsequently, the operation of the door 1 configured in this way will be described.

First, as shown in FIG. 6A, in the fully closed state, the finger pinching prevention portion 80 does not protrude outside the target space 5 from the tip portion 74a of the mating portion 74, so that the finger pinching prevention portion 80 is pressed. The finger pinching prevention portion 80 becomes inconspicuous as compared with the case where the tip portion 74a of the mating portion 74 is projected to the outside of the target space 5. Further, since the plane shape of the combined portion 74 of the finger pinching prevention portion 80 is the above-mentioned bent line shape, the finger pinching prevention portion 80 is compared with the case where the plane shape of the finger pinching prevention portion 80 is a curved shape including an arcuate portion. The uniformity of the shape between the 80 and the peripheral member can be maintained. Further, since the minimum distance between the tip portion 74a of the mating portion 74 and the finger pinching prevention portion 80 is the distance at which the user's finger cannot be inserted, the safety of the door 1 can be ensured.

Further, as shown in FIGS. 6 (b) to 6 (d), in the non-fully opened / closed state and the fully opened state, the finger pinching prevention portion 80 has the above-mentioned polygonal line shape of the mating portion 74, so that the finger scissors are pinched. Compared with the case where the planar shape of the prevention portion 80 is a curved shape including an arc-shaped portion, the uniformity of the shape between the finger pinching prevention portion 80 and the peripheral member can be maintained. Further, since the minimum distance between the tip portion 74a of the mating portion 74 and the finger pinching prevention portion 80 is the distance at which the user's finger cannot be inserted, the safety of the door 1 can be ensured.

(effect)
As described above, according to the embodiment, it is possible to prevent the finger pinching prevention portion 80 from coming into contact with the door tail side vertical frame 11 regardless of the rotational state of the door body 20 with respect to the flat shape of the finger pinching prevention portion 80. Since it is formed into a bent line shape having at least two bent portions, the finger pinching prevention portion 80 and the door tail side vertical frame 11 are between each other regardless of the rotating state of the door body 20. It is possible to prevent the user's finger from being caught in the gap and maintain the usability of the door 1. Further, in particular, as compared with the case where the plane shape of the finger scissors prevention portion 80 is a curved shape including an arc-shaped portion, the peripheral members are designed to have a plane shape centered on a straight line as compared with the conventional case, and therefore, the finger scissors It is possible to maintain the uniformity of the shapes of the prevention portion 80 and the peripheral members. Therefore, the design of the finger pinching prevention portion 80 and the peripheral members can be easily harmonized, and the design of the door 1 can be maintained.

Since the finger pinching prevention portion 80 is formed so that the finger pinching prevention portion 80 does not protrude outside the target space 5 from the door tail side vertical frame 11 in the fully closed state, the finger pinching prevention portion 80 is formed in the fully closed state. Since the finger pinching prevention portion 80 is less noticeable than the case where the vertical frame 11 on the door tail side is projected to the outside of the target space 5, it is possible to maintain the design of the door 1 in the fully closed state. ..

Further, the door body 20 is arranged so that the rotation center position C of the hinge portion is located outside the target space 5 from the center line along the finding direction (left-right direction) of the door body 20 in the fully closed state. The first distance X1 in the finding direction between the hinge side bending portion 82 and the rotation center position C is equal to or less than the second distance X2 in the finding direction between the door tail side bending portion 81 and the rotation center position C. As described above, since the hinged portion 81 on the door tail side and the bent portion 82 on the door end side are arranged, the finger pinching is performed in the non-fully opened / closed state closer to the fully opened state than in the case where the first distance X1 exceeds the second distance X2. The gap between the prevention portion 80 and the door tail side vertical frame 11 can be increased. As a result, it is possible to prevent the finger pinching prevention portion 80 from coming into contact with the door tail side vertical frame 11 due to the influence of the manufacturing accuracy of the finger pinching prevention portion 80 or the door tail side vertical frame 11 (for example, the influence of distortion, distortion, etc. of the member).

Since the door end side side portion 84 is formed, the finger pinch prevention portion 80 is in the fully opened state (or in the non-fully opened / closed state close to the fully opened state) as compared with the case where the first inclination angle α1 is made larger than the second inclination angle α2. The gap between the door and the vertical frame 11 on the door tail side can be reduced. As a result, it is possible to prevent a finger from being caught in the gap, so that the safety of the door 1 can be further ensured.

Further, in the fully closed state, the end portion of the finger pinching prevention portion 80 on the door tail side and the end portion of the door tail side vertical frame 11 on the door end side are substantially flush with each other along the prospective direction. Since the finger pinching prevention portion 80 is formed, other members (for example, the first airtight portion 16 and the like) are targeted through the gap between the finger pinching prevention portion 80 and the door tail side vertical frame 11 in the fully closed state. It is possible to suppress the visibility from the outside of the space 5, and it is possible to further maintain the design of the door 1 in the fully closed state.

Further, the cover portion 86 provided on the finger pinching prevention portion 80 is a cover portion for covering the abutting portion 90 between the door tail side portion of the outer surface material 41 and the door tail side portion of the inner surface material 42. Since the 86 is provided, it is possible to prevent water or the like from entering the inside of the door body 20 through the butt portion 90, and the members (for example, the door frame 30 or the like) arranged inside the door body 20 can be prevented from rusting. It becomes possible to suppress.

Further, since the cover portion 86 is formed so as not to come into contact with the first airtight portion 16 provided on the door tail side vertical frame 11 in either the fully opened state or the non-fully opened / closed state, the cover portion 86 is fully opened. In either the state or the non-fully opened / closed state, the contact between the cover portion 86 and the first airtight portion 16 can prevent the first airtight portion 16 from rolling up, and the door tail side vertical frame 11 in the fully closed state. It is possible to avoid a decrease in airtightness between the door body 20 and the door body 20.
