Description

  The present invention relates to a door.

  Conventionally, for a door attached to an opening of a building, when opening and closing the door body constituting the door, a user is provided in a gap between the door body and the frame material on the door butt side provided in the opening. A door has been proposed that can prevent fingers from being pinched. Such a door is generally a door installed in a target space such as a toilet booth, a door body pivotally supported by a suspension shaft attached to a frame material on the door bottom side, and a door of the door body. A side edge member attached to the end on the butt side, a finger pinching prevention device attached to the outer side surface of the target space in the door body, and a wall side edge member attached to the frame member on the door butt side ing. Moreover, the planar shape of the side edge material is formed in a convex shape in which the surface facing the wall side edge member is a curved shape (specifically, an arc shape). Further, the planar shape of the finger pinching prevention device is formed in a convex shape in which the surface facing the wall side edge member has a curved shape (specifically, an arc shape). Moreover, the planar shape of the wall side edge member is formed in a concave shape in which the surface facing the side edge material or the finger pinching prevention device is a curved shape. The side edge material, the finger pinching prevention device, and the wall side edge member allow the size of the gap between the wall side edge member and the side edge member or the finger pinching prevention device to be independent of the rotating state of the door body.

Specifically, it is a position where the door body 20 does not contact the door bottom side vertical frame 11 regardless of the rotation state of the door body 20, and is in a fully closed state (or a fully closed state and a non-fully closed state close to the fully closed state). The door 20 contacts the edge 16a of the first airtight portion 16 in the open / closed state, and the door 20 contacts the edge 16a in the fully open state (or the fully open state and the non-fully open / closed state close to the fully open state). It is installed in a position that does not. The reason for setting such an installation position is as follows. 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 wear of the edge portion 16a due to such a contact state or increase resistance due to the edge portion 16a when the door body 20 is rotated.

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

(Configuration-Details of the configuration of the door-Finger scissors prevention unit-Details of the configuration of the finger scissors prevention unit-First feature)
Next, details of the configuration of the finger scissors prevention unit 80 will be described. First, as to the first feature of the configuration of the finger scissor prevention unit 80, as shown in FIGS. 4 to 6, the planar shape of the finger scissor prevention unit 80 (the shape when viewed from above the finger scissor prevention unit 80). However, regardless of the rotation state of the door body 20, the finger scissors prevention portion 80 has a polygonal line shape that can avoid contact with the door-side vertical frame 11, and has a polygonal line shape having at least two bent portions. Is formed. Here, the “polyline shape” is a side portion that forms a bent portion, and means a shape that includes only a side portion formed in a straight line. The reason why the planar shape of the finger scissor prevention unit 80 is the above-mentioned polygonal line shape is that, for example, when the planar shape of the finger scissor prevention unit 80 is a curved shape including an arcuate portion, FIG. As shown in FIG. 4, the peripheral members of the finger scissors prevention unit 80 (for example, the door body 20, the door butt side vertical frame 11, etc., hereinafter referred to as “peripheral members”) are designed in a planar shape centered on a straight line. Therefore, it becomes difficult to maintain the uniformity of the shape of the finger scissor prevention unit 80 and the peripheral member regardless of the rotation state of the door body 20, so that the finger scissor prevention unit 80 and the peripheral member This is to avoid such a problem because it is difficult to achieve harmony of the design.

  Specifically, as shown in FIGS. 4 to 5, the finger scissors prevention unit 80 includes a door butt side bent portion 81 positioned closest to the door butt in the fully closed state and a door tip side most in the fully closed state. It is formed in a polygonal line shape having a door end side bent portion 82 located. More specifically, it is located closest to the door butt side in the fully closed state (in FIG. 4, it is located so as to reach the door butt side bent portion 81 from the door butt side end of the finger scissors prevention unit 80). Side end 83 and the door end that is located closest to the door end in the fully closed state (in FIG. 4, the door end is positioned so as to reach the door end side bent portion 82 from the end of the finger scissors prevention portion 80 on the door end side). It is a polygonal line shape composed of a side side portion 84 and an intermediate side portion 85 extending from the door butt side bent portion 81 to the door tip side bent portion 82, and the door butt is located between the door butt side side portion 83 and the intermediate side portion 85. The side bent portion 81 is located, and the door tip side bent portion 82 is formed in a polygonal line shape between the door tip side portion 84 and the intermediate side portion 85. In addition, regarding the details of the installation positions of the door bottom side portion 83, the door tip side portion 84, and the intermediate side portion 85, specifically, as shown in FIG. 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 imaginary line L1” is an imaginary line indicating the setting range of the shape of the finger scissor prevention unit 80, and the finger scissor prevention unit 80 and the door butt side regardless of the rotation state of the door body 20. It is a virtual line which shows the range used as the maximum shape which the vertical frame 11 does not contact. The “second imaginary line L2” is an imaginary line indicating the setting range of the shape of the finger scissor prevention unit 80, and the finger is caught in the door-side vertical frame 11 regardless of the rotation state of the door body 20. Imaginary line indicating a range of a shape in which the distance between the portion (in the embodiment, the tip portion 74a of the summing unit 74) and the finger scissor prevention unit 80 is the maximum distance at which the user's finger cannot be inserted It is.

  Moreover, although the installation method of the door butt side bending part 81 and the door tip side bending part 82 is arbitrary, as shown in FIG. 4, in the embodiment, the rotation center position of the door tip side bending part 82 and the hinge part. The distance X1 (hereinafter referred to as “first distance X1”) in the direction of finding (left and right direction) between C and C is the direction of finding (left and right direction) between the door bottom side bent portion 81 and the rotation center position C. ) Distance X2 (hereinafter referred to as “second distance X2”) or less. Specifically, the first distance X1 is less than the second distance X2, and the door bottom side bent portion 81 and the door tip side bent portion 82 are positioned between the first virtual line L1 and the second virtual line L2. It is installed so as to be positioned substantially on the third virtual line L3. Here, the “third imaginary line L3” refers to the end of the door body 20 in the end of the side surface outside the target space 5 of the door body 20 in the trajectory of the door body 20 accompanying the rotation of the door body 20. It is an imaginary line indicating the locus of the unit 21. The reason why the first distance X1 is set to be equal to or smaller than the second distance X2 is as follows. That is, when the first distance X1 is greater than the second distance X2 as shown in FIG. 7, the first distance X1 is fully opened compared to the case where the first distance X1 is less than or equal to the second distance X2 as shown in FIGS. Since the gap S2 (see FIGS. 6 (c) and 7 (b)) between the finger scissor prevention unit 80 and the tip 74a of the summing unit 74 becomes smaller in the non-fully opened / closed state close to the state, the finger scissors There is a possibility that the finger scissor prevention unit 80 may come into contact with the summing unit 74 due to the influence of the manufacturing accuracy of the prevention unit 80 or the door bottom side vertical frame 11 (particularly, the summing unit 74) (for example, the influence of distortion, distortion, etc. of the members). This is for avoiding this and maintaining the usability of the door 1. Further, the reason why the door bottom side bent portion 81 is positioned substantially on the third virtual line L3 is as follows. That is, when the door butt side bent portion 81 is positioned substantially in the vicinity of the first virtual line L2, the door butt side bent portion 81 is fully closed compared to the case where the door butt side bent portion 81 is positioned substantially on the third virtual line L3. Since the gap S1 (see FIG. 6B) between the finger pinching prevention unit 80 and the tip end portion 74a becomes large in the non-fully opened / closed state close to the state, there is a possibility that the finger may be caught in the gap S1. This is for avoiding this and further ensuring the safety of the door 1.

  Moreover, although it is arbitrary about the specific structure of the door bottom side part 83 and the door tip side part 84, in embodiment, as shown in FIG. 4, with respect to the door body 20 of the door tip side part 84 An inclination angle α1 (hereinafter referred to as “first inclination angle α1”) is formed to be equal to or less than an inclination angle α2 (hereinafter referred to as “second inclination angle α2”) of the door-side side portion 83 with respect to the door body 20. Has been. Specifically, the distance X3 (hereinafter referred to as “third distance X3”) in the direction of finding (left-right direction) between the door-side end of the finger scissor prevention unit 80 and the door-side bent portion 82. However, it is longer than the distance X4 (hereinafter referred to as “fourth distance X4”) in the direction of finding (left-right direction) between the end portion on the door butt side of the finger scissors prevention portion 80 and the door butt side bent portion 81. It is formed to become. Here, the reason why the first inclination angle α1 is made equal to or smaller than the second inclination angle α2 is as follows. That is, when the first inclination angle α1 is larger than the second inclination angle α2 as shown in FIG. 8, the first inclination angle α1 is set to be equal to or smaller than the second inclination angle α2 as shown in FIGS. Compared to the case, in the non-fully opened / closed state close to the fully opened state, there is a gap S3 (see FIGS. 6D and 8B) between the finger pinching prevention unit 80 and the tip 74a of the summing unit 74. Since it becomes large, there is a possibility that a finger may be caught in the gap S3, so that this is avoided and the safety of the door 1 is further secured.

  Further, although the specific configuration of the intermediate side portion 85 is arbitrary, 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. Is formed. Specifically, in the fully-closed state, the distance in the finding direction (left-right direction) between the door bottom side bent portion 81 and the door tip side bent portion 82 (that is, the sum of the first distance X1 and the second distance X2). The distance) is longer than either the third distance X3 or the fourth distance X4. Thereby, 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, it is possible to maintain the uniformity of the shapes of the finger scissors prevention unit 80 and the peripheral members in the fully closed state. Therefore, it is easy to achieve harmony between the design of the finger scissors prevention unit 80 and the peripheral member.

  According to the first feature, the user's finger is prevented from being caught in the gap between the finger pinching prevention unit 80 and the door butt side vertical frame 11 regardless of the rotation state of the door body 20. In addition, while maintaining the usability of the door 1, the uniformity of the shape of the finger scissor prevention unit 80 and the peripheral members is maintained as compared with the case where the planar shape of the finger scissor prevention unit 80 is a curved shape including an arcuate portion. can do. Accordingly, the design of the finger scissor prevention unit 80 and the peripheral member can be easily harmonized, so that the design of the door 1 can be maintained.

(Configuration-Details of the configuration of the door body-Finger scissors prevention unit-Details of the configuration of the finger scissors prevention unit-Second feature)
Next, as to the second feature of the configuration of the finger scissor prevention unit 80, as shown in FIG. 4, the finger scissor prevention unit 80 protrudes to the outside of the target space 5 rather than the door bottom side vertical frame 11 in the fully closed state. The finger scissors prevention part 80 is formed so as not to cause a problem. Here, the reason why the finger scissor prevention unit 80 is formed so as not to protrude outside the target space 5 from the door-side vertical frame 11 is as follows. That is, in the fully closed state, when the finger scissor prevention unit 80 has a shape that protrudes to the outside of the target space 5 from the door-side vertical frame 11, the finger scissor prevention unit 80 from the outer side of the target space 5 This is to avoid this problem.

  Specifically, as described above, the finger scissors prevention unit 80 has a polygonal line shape having a door-end side bent portion 81 and a door-end side bent portion 82, and includes a door-end side portion 83, a door-end side portion. 84, and a polygonal line shape composed of the intermediate side portion 85, and a door bottom side bent portion 81 is positioned between the door bottom side portion 83 and the intermediate side portion 85, and the door tip side portion 84 and the intermediate side portion. It is formed in the shape of a broken line in which the door end side bent portion 82 is positioned between 85 and 85. Moreover, about the detail of the installation position of these door butt side parts 83, the door tip side part 84, and the intermediate | middle side part 85, specifically, as shown in FIG. 4, the position in the installation area | region T mentioned above. In addition, the intermediate side portion 85 is installed at a position that does not protrude outside the target space 5 with respect to the door bottom side vertical frame 11 in the fully closed state.

  Further, the specific configuration of the finger scissor 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 bottom 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 distance X5 (hereinafter referred to as the front-rear direction) is a position substantially on the third imaginary line L3 and between the door-side bent portion 81 and the door body 20. , Referred to as “fifth distance X5”) and the distance X6 (hereinafter referred to as “sixth distance X6”) in the prospective direction (front-rear direction) between the door-end side bent portion 82 and the door body 20 are the same. Is formed in a polygonal line shape in which the door bottom side bent portion 81 and the door tip side bent portion 82 are located. Thereby, compared with the case where the door-end side bending portion 81 and the door-end side bending portion 82 are not substantially flush with each other along the finding direction (left-right direction) in the fully closed state, the finger scissors prevention portion 80 and the peripheral member Therefore, it is possible to maintain the design of the door 1 in the fully closed state.

  In addition, as shown in FIG. 4, in the fully closed state, the door butt side end of the finger scissor prevention unit 80 and the door end side end of the door butt side vertical frame 11 (in the embodiment, the summing unit 74). Are formed so as to be substantially flush with each other along the prospective direction (front-rear direction). Specifically, in the fully closed state, the end portion on the door butt side of the finger scissors prevention portion 80 and the tip end portion 74a of the summing portion 74 are in contact with the end portion on the door butt side of the door body 20 in the expected direction (front-rear direction). Are formed so as to be substantially flush with each other. Thereby, other members (for example, the 1st airtight part 16 grade | etc.) Can be seen from the outer side of the object space 5 through the clearance gap between the finger | toe pinching prevention part 80 and the door butt side vertical frame 11 in a fully closed state. Therefore, the design of the door 1 in the fully closed state can be further maintained.

  According to the second feature, the finger scissor prevention unit 80 is more conspicuous than when the finger scissor prevention unit 80 is protruded to the outside of the target space 5 with respect to the door bottom side vertical frame 11 in the fully closed state. As a result, the design of the door 1 in the fully closed state can be maintained.

(Configuration-details of the structure of the door-finger scissors prevention part-details of the structure of the finger scissors prevention part-other structures)
Next, another structure of the configuration of the finger scissors prevention unit 80 will be described. As shown in FIGS. 4 and 5, the finger pinching prevention unit 80 is provided with a cover portion 86, a mounting hole 87, a first fitting portion 88, and a second fitting portion 89.

  The cover portion 86 covers the abutting portion 90 between the door butt side portion (the door butt side expected surface) of the outer surface material 41 and the door butt side portion (the door butt side expected surface) of the inner surface material 42. Cover means. The cover portion 86 is formed of, for example, an aluminum material, a steel material, a stainless material, or a resin material. The cover portion 86 is directed from the edge of the finger scissors prevention portion 80 toward the inside of the target space 5. It arrange | positions so that it may protrude and it is connected with respect to the finger | toe pincer prevention part 80. FIG. Further, although the specific shape of the cover portion 86 is arbitrary, in the embodiment, as shown in FIGS. 6 (b) to 6 (d), in either the fully opened state or the non-fully opened / closed state. Also, the cover portion 86 is formed in a shape so as not to come into contact with the first airtight portion 16 provided in the door bottom 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). And the vertical length (height) of the cover portion 86 is shorter (or substantially the same) as the vertical length (height) of the door body 20. ). Accordingly, the first airtight portion 16 is lifted by the contact between the cover portion 86 and the first airtight portion 16 provided on the door butt side vertical frame 11 in either the fully open state or the non-fully opened / closed state. Since it can suppress, it can avoid that the airtightness between the door-end side vertical frame 13 and the door body 20 falls in a fully closed state. Since such a cover portion 86 can suppress water and the like from entering the inside of the door body 20 through the abutting portion 90, a member (for example, the door frame 30) disposed inside the door body 20 It is possible to suppress rusting.

  Further, the attachment hole 87 is for inserting a fixing tool (for example, a screw) for attaching the finger pinching prevention portion 80 and the cover portion 86 to the door body 20 (specifically, the door butt side longitudinal bone 31). A plurality of through-holes are provided side by side in the cover portion 86 along the vertical direction. Further, the first fitting portion 88 is for fitting a fixing tool (for example, a molding clip or the like), and extends in the vertical direction on the door end side portion 84 and the intermediate side portion 85 of the finger scissor prevention portion 80. Are installed side by side. Further, the second fitting portion 89 is for fitting a fixing tool (for example, a cap or the like), and is provided at least one or more on the door butt side portion 83 of the finger scissors prevention portion 80. The fixing hole can be easily attached to the finger scissor prevention unit 80 or the door body 20 by the attachment hole 87, the first insertion part 88, and the second insertion part 89. It can be done efficiently.

  Further, the finger scissor prevention unit 80 configured as described above can be manufactured by an arbitrary method or material. For example, in order to improve the manufacturability of the finger scissor prevention unit 80, a ready-made finger scissor prevention unit 80 is manufactured. A mounting hole 87 is drilled in a molding material (for example, an aluminum profile, etc.) that is a molding material and has a door butt side portion 83, a door tip side portion 84, an intermediate side portion 85, and a cover portion 86. It may be manufactured. Alternatively, the present invention is not limited thereto, and the door bottom side portion 83, the door end side portion 84, the intermediate side portion 85, and the cover portion 86 are formed by bending and forming a plate-like body made of aluminum, steel, or stainless steel. The mounting hole 87 may be manufactured by molding integrally and at any time before and after the bending.

(Door action)
Then, the effect | action of the door 1 comprised in this way is demonstrated.

  First, as shown in FIG. 6 (a), in the fully closed state, the finger scissors prevention unit 80 does not protrude outside the target space 5 from the tip part 74a of the summing unit 74. Compared with the case where the tip part 74a of the summing part 74 is protruded to the outside of the target space 5, the finger scissors prevention part 80 becomes inconspicuous. In addition, since the planar shape of the summing unit 74 of the finger scissor prevention unit 80 is the above-described polygonal line shape, the finger scissor prevention unit is compared with a case where the planar shape of the finger scissor prevention unit 80 is a curved shape including an arcuate portion. The uniformity of the shape of 80 and the peripheral members can be maintained. Moreover, since the minimum distance between the front-end | tip part 74a of the summoning part 74 and the finger | toe pincer prevention part 80 is a distance which cannot insert a user's finger | toe, the safety | security of the door 1 can be ensured.

  In addition, as shown in FIG. 6B to FIG. 6D, the finger scissors prevention unit 80 in the non-fully opened / closed state and the fully opened state has a plane shape of the summing portion 74, so that the finger scissors Compared with the case where the planar shape of the prevention unit 80 is a curved shape including an arcuate portion, the uniformity of the shape of the finger scissor prevention unit 80 and the peripheral members can be maintained. Moreover, since the minimum distance between the front-end | tip part 74a of the summoning part 74 and the finger | toe pincer prevention part 80 is a distance which cannot insert a user's finger | toe, the safety | security of the door 1 can be ensured.

(effect)
As described above, according to the embodiment, the planar shape of the finger scissor prevention unit 80 can be prevented from contacting the door bottom side vertical frame 11 regardless of the rotation state of the door body 20. Since it has a polygonal line shape and is formed in a polygonal line shape having at least two or more bent parts, the finger scissors prevention part 80 and the door butt side vertical frame 11 can be The user's finger can be prevented from being caught in the gap, and the usability of the door 1 can be maintained. In particular, compared to the case where the planar shape of the finger scissor prevention portion 80 is a curved shape including an arcuate portion, the peripheral members are conventionally designed to have a planar shape centered on a straight line. The uniformity of the shape of the prevention part 80 and the peripheral member can be maintained. Accordingly, the design of the finger scissor prevention unit 80 and the peripheral member can be easily harmonized, so that the design of the door 1 can be maintained.

  Since the finger scissor prevention unit 80 is formed so that the finger scissor prevention unit 80 does not protrude outside the target space 5 from the door butt side vertical frame 11 in the fully closed state, the finger scissor prevention unit 80 is formed in the fully closed state. Compared to the case where the door scissors vertical frame 11 is protruded to the outside of the target space 5, the finger scissors prevention portion 80 becomes inconspicuous, so that the design of the door 1 in the fully closed state can be maintained. .

  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 with respect to the center line along the direction in which the door body 20 is found (left-right direction) in the fully closed state, The first distance X1 in the finding direction between the door-end side bent 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-end side bent portion 81 and the rotation center position C. As described above, since the door bottom side bent portion 81 and the door tip side bent portion 82 are arranged, the finger scissors in the non-fully opened / closed state closer to the fully opened state than when the first distance X1 exceeds the second distance X2. The clearance gap between the prevention part 80 and the door butt side vertical frame 11 can be enlarged. Thereby, it is avoided that the finger scissors prevention part 80 contacts the door bottom side vertical frame 11 due to the influence of the manufacturing accuracy of the finger scissors prevention part 80 or the door bottom side vertical frame 11 (for example, the influence of the distortion, distortion, etc. of the members). Therefore, the usability of the door 1 can be further maintained.

Since the door end side portion 84 is formed, the finger pinching prevention unit 80 in the fully open state (or a non-fully opened / closed state close to the fully open state) as compared with the case where the first inclination angle α1 is larger than the second inclination angle α2. And the gap between the door bottom side vertical frame 11 can be reduced. As a result, it is possible to avoid 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 door butt side end of the finger scissor prevention unit 80 and the door butt side end of the door butt side vertical frame 11 are substantially flush with each other along the prospective direction. Since the finger scissor prevention part 80 is formed, other members (for example, the first airtight part 16 and the like) are targeted through a gap between the finger scissor prevention part 80 and the door butt side vertical frame 11 in the fully closed state. Visible from the outside of the space 5 can be suppressed, and the design of the door 1 in the fully closed state can be further maintained.

  Further, the cover portion 86 is provided in the finger scissors prevention portion 80, and covers the butted portion 90 between the door butt side portion of the outer surface material 41 and the door butt side portion of the inner surface material 42. 86 is provided, water can be prevented from entering the inside of the door body 20 through the abutting portion 90, and the members (for example, the door frame 30) disposed inside the door body 20 can be rusted. It becomes possible to suppress.

  Further, since the cover portion 86 is formed so that the cover portion 86 does not come into contact with the first airtight portion 16 provided on the door bottom side vertical frame 11 in either the fully opened state or the non-fully opened / closed state, the cover portion 86 is fully opened. It is possible to suppress the first airtight portion 16 from being lifted by contact between the cover portion 86 and the first airtight portion 16 in either the state or the non-fully opened / closed state. It can be avoided that the airtightness between the door 20 and the door 20 is lowered.
