  The frame material body 15 is a basic structure of the door bottom side vertical frame 11 (or the door end side vertical frame 12). The frame body 15 is a hollow body formed so that a cross-sectional shape along the XY plane is a substantially U-shape opened outward in the left-right direction, and the vertical direction of the opening 2 Is formed over substantially the entire length. Further, the specific configuration of the frame body 15 is arbitrary. For example, as shown in FIG. 2, a portion corresponding to the door body 20 in the frame body 15 is recessed toward the outside in the left-right direction. Thus, a space capable of avoiding interference between the frame body 15 and the door body 20 while accommodating the door body 20 is formed. In addition, from the viewpoint of the design of the frame body 10, the frame material body 15 of the door bottom side vertical frame 11 and the frame material body 15 of the door end side vertical frame 12 are set to have the same shape and size.

  The fixing member 16 is for fixing the frame member body 15 to the housing of the building and reinforcing the frame member body 15. The fixing member 16 is formed of a plate-like body. Specifically, as shown in FIG. 2, the length of the fixing member 16 in the front-rear direction is a U-shaped open end of the frame body 15. The length of the fixing member 16 is substantially the same (or longer than that), and the length of the fixing member 16 in the vertical direction is shorter than the length of the frame body 15 in the vertical direction. . Further, a plurality of fixing members 16 are arranged along the vertical direction at a predetermined interval on the U-shaped open end side of the frame main body 15 (the outer end side in the left-right direction of the frame main body 15). It is arranged and fixed to the frame material main body 15 and the building frame by welding or the like.

(Configuration-Locking device mounting structure)
Next, the attachment structure of the locking device 50 will be described. The door 1 includes an attachment structure for attaching the locking device 50 to the door body 20. As shown in FIGS. 2 and 3, the mounting structure includes a backlash suppressing portion 70 (backlash suppressing means) for suppressing backlash of the outdoor operation shaft 52. Here, the reason why the backlash suppressing portion 70 for suppressing backlash of the outdoor operation shaft 52 is provided is as follows. That is, as shown in FIGS. 2 and 3, the inner diameter of the outdoor through hole 41 a is set to be larger than the outer diameter of the outdoor operation shaft 52, and the outdoor cover portion 53 (particularly, the outdoor surface The outer diameter of the outdoor side cover portion 53) on the material 41 side is set slightly larger than the inner diameter of the outdoor side through hole 41a. In these settings, as shown in FIGS. 2 and 3, when the length of the outdoor operation shaft 52 in the axial direction (the length in the front-rear direction of the outdoor operation shaft 52 in the drawing) is relatively long, When a locking operation (for example, a locking operation or an unlocking operation) is performed by the user via the outdoor operation shaft 52, the locking device is compared with a case where the axial length of the outdoor operation shaft 52 is relatively short. The backlash of the outdoor operation shaft 52 with respect to the main body 51 increases. In this case, for example, a gap between the outer peripheral end of the outdoor cover 53 and the outer peripheral end of the outdoor through-hole 41a (that is, the amount of engagement of the outdoor cover 53) is not stable. In order to avoid this, the outdoor through hole 41a may be exposed to the outside because a part of the outdoor through hole 41a is not covered by the outdoor cover 53 when the amount is smaller than the amount. It is. A backlash suppressing portion 70 for suppressing backlash of the indoor operation shaft 54 may be provided, but as shown in FIGS. 2 and 3, the length of the indoor operation shaft 54 in the axial direction (see FIG. 2 and 3, the length of the indoor operation shaft 54 in the front-rear direction is relatively short. Therefore, even if the user performs a lock operation via the indoor operation shaft 54, for example, the indoor operation shaft 54 Since the amount of rattling is small, it is considered that the possibility that the indoor side through hole 42a is exposed to the outside is extremely low. For this reason, in the embodiment, the rattling suppressing portion 70 for suppressing the rattling of the indoor operation shaft 54 is not provided.

  As shown in FIGS. 2 and 3, the rattling suppressing portion 70 is provided between the outdoor surface material 41 and the locking device main body 51 inside the door body 20. As shown in FIGS. 3 and 5, the rattling suppressing portion 70 is formed of a substantially plate-like body whose cross-sectional shape along the YZ plane is an inverted U-shape. Includes a first side 71, a second side 72, and a third side 73.

(Configuration-Locking device mounting structure-First side portion of the rattling suppressing portion)
The 1st side part 71 is a side part for fixing the rattling suppression part 70 with respect to a support target. Here, the “support target” refers to, for example, the constituent elements of the door body 20 (for example, the outdoor surface material 41, the door-end side longitudinal force bone 32, etc.) and the constituent elements of the locking device 50 (for example, the locking device). In the embodiment, the concept is described as the outdoor surface material 41. The first side portion 71 is formed so as to protrude downward from the outdoor side end portion of the third side portion 73, and is provided substantially parallel to the outdoor side surface material 41. Specifically, as shown in FIG. 3, the outdoor surface material 41 is provided so as to face the outdoor side through hole 41 a and to come into contact with the outdoor surface material 41. It is fixed with an adhesive tape or an adhesive.

  As shown in FIGS. 3 and 5, the first side portion 71 has a first insertion hole 71 a. The first insertion hole 71a is for inserting the outdoor operation shaft 52, and is provided in a portion corresponding to the outdoor through hole 41a in the first side portion 71. Specifically, FIG. As shown, the center point of the first insertion hole 71a is provided so as to be positioned substantially on the same straight line as the center point of the outdoor through hole 41a. Further, the shape and size of the first insertion hole 71a are arbitrary, but in the embodiment, the first insertion hole 71a is set to have the same shape and size as the inner diameter of the outdoor through hole 41a. However, the present invention is not limited to this. For example, although the shape is the same as the shape of the outdoor through hole 41a, it may be set larger than the inner diameter of the outdoor through hole 41a.

(Configuration-Locking device mounting structure-Second side portion of rattling suppression portion)
The second side portion 72 is a side portion for suppressing backlash of the outdoor operation shaft 52. As shown in FIGS. 3 and 5, the second side portion 72 is formed so as to protrude downward from the indoor side end portion of the room in the third side portion 73, and the outdoor side surface material 41. Are provided so as to be substantially parallel to the first side portion 71.

  As shown in FIGS. 3 and 5, the second side portion 72 is formed with a second insertion hole 72 a. The second insertion hole 72a has a backlash of the outdoor operation shaft 52 so that the outdoor through hole 41a is covered by the outdoor cover portion 53 by inserting the outdoor operation shaft 52 through the second insertion hole 72a. This is an insertion hole for suppressing sticking. The second insertion hole 72a is provided in a portion corresponding to the outdoor side through hole 41a and the first insertion hole 71a in the second side portion 72. Specifically, as shown in FIG. The center point of the hole 72a is provided so as to be positioned substantially on the same straight line as the center point of the outdoor through hole 41a, the center point of the first insertion hole 71a, and the center point of the insertion hole of the locking device main body 51. Further, the shape and size of the second insertion hole 72a are arbitrary, but in the embodiment, the second insertion hole 72a is set to have the same shape as the outer diameter of the outdoor operation shaft 52 and the outer diameter of the outdoor operation shaft 52. It is set to a larger size.

In addition, the specific configuration of the second insertion hole 72a is arbitrary. In the embodiment, the configuration is as follows. That is, as shown in FIG. 3, the length K ₁ of the gap between the second insertion hole 72 a of the backlash suppressing portion 70 and the outdoor operation shaft 52 is expressed by the following formula (1) to the following formula (3). It is set to satisfy.
K ₁ <K ₀ × T ₁ / T ₀ Formula (1)
K ₀ > 0 ... Formula (2)
K ₁ > 0 ... Formula (3)
(here,
K ₀ : the length between the outer peripheral end of the side surface on the outdoor outer surface material 41 side in the outdoor outer cover 53 and the outer peripheral end of the outdoor through hole 41a of the outdoor surface material 41,
K ₁ : the length of the gap between the second insertion hole 72a of the backlash suppressing portion 70 and the outdoor operation shaft 52,
T ₀ : length from the locking device body 51 to the outdoor surface material 41,
T ₁ : Length from the locking device main body 51 to the second insertion hole 72a (in FIG. 3, the second insertion formed on the side of the room side of the room from the locking device main body 51 to the second side portion 72) Shows the length up to the hole 72a))

Here, the reason for setting the length K ₁ of the gap on the basis of these formulas (1) into equation (3) are as shown below. That is, for example, when the length K _{1 of the} gap is set to the same length as the mutual length K ₀ , the amount of play of the outdoor operation shaft 52 is the length K _{1 of the} gap. When the amount reaches the same level as (= K ₀ ), a part of the outdoor side through hole 41a is not covered by the outdoor side cover part 53, so that the outdoor side through hole 41a may be exposed to the outside. On the other hand, if the gap length K ₁ is set to a value close to zero, although rattling of the outdoor side operation shaft 52 is hardly caused, mounting the outdoor operating shaft 52 relative to the locking device main body 51 At this time, since it is not possible to secure a gap (that is, a gap between the second insertion hole 72a and the outdoor operation shaft 52 (specifically, the operation shaft main body 52a)), the attachment may be difficult. To avoid the above problems, it is set to a length K ₁ of the gap on the basis of these formulas (1) into equation (3).

For details on the length K ₁ of the gap, specifically, as shown in FIG. 3, the position of the second insertion hole 72a of the rattle suppression portion 70 is locking device main body 51 and the outdoor side surface member 41 so as to be substantially intermediate position between (i.e., such that _{T 1 ≒ T 0/2)} , since the backlash suppression unit 70 is provided, the _{K 1} ≒ _K 0/2 (specifically , A length slightly shorter than K _0/2 . With this setting, when the outdoor operation shaft 52 is attached to the locking device main body 51 while preventing the outdoor through hole 41a of the outdoor surface material 41 from being exposed to the outside in the second insertion hole 72a. Therefore, it is possible to maintain the workability of the locking device 50 while ensuring the safety when the door 1 is used.

Along with setting the length K ₁ the gap, as shown in FIGS. 3-5, the size of the second insertion hole 72a of the rattle suppression unit 70, the following equation (4), the following equation (5 ) Is set to satisfy.
A ₁ = B ₁ + K ₁ × 2 Formula (4)
A ₂ = B ₂ + K ₁ × 2 Formula (5)
(here,
A ₁ : Length in a direction substantially perpendicular to the juxtaposed direction of the first connecting portion 52b and the second connecting portion 52c of the outdoor operation shaft 52 in the second insertion hole 72a of the rattling suppressing portion 70 (in FIG. The length of the second insertion hole 72a in the left-right direction),
A ₂ : The length in the direction in which the first connection portion 52b and the second connection portion 52c of the outdoor operation shaft 52 are juxtaposed in the second insertion hole 72a of the rattling suppression portion 70 (in FIG. 5, the second insertion hole 72a). Length in the vertical direction)
B ₁ : Length in a direction substantially orthogonal to the juxtaposed direction of the first connecting portion 52b and the second connecting portion 52c of the outdoor operation shaft 52 in the operation shaft main body 52a of the outdoor operation shaft 52 (in FIG. The lateral length of the outer operation shaft 52),
B ₂ : Length from the outer edge end portion of the first connection portion 52b to the outer edge end portion of the second connection portion 52c in the outdoor operation shaft 52 (the length in the vertical direction of the outdoor operation shaft 52 in FIG. 4))

Specifically, as described above, since the position of the second insertion hole 72a is a substantially intermediate position between the locking device main body 51 and the outdoor surface material 41, as shown in FIG. In the left-right direction A ₁ = B ₁ + X (where “X” means a value slightly smaller than K ₀ ), and the vertical length A ₂ = B of the second insertion hole 72a. It is set so that the second insertion hole 72a fits in an area 80 (hereinafter referred to as “settable area 80”) that becomes ₂ + X. Further, the shape and size of the second insertion hole 72a can be set to substantially the same shape and size as the settable region 80 of FIG. 5, but in this case, the second insertion hole Since the length of the gap in each of the left oblique direction and the right oblique direction is relatively long among the gaps between the outdoor operation shaft 52a and 72a, the outdoor operation shaft 52 is arranged in the left oblique direction or the right oblique direction. If there is a backlash, the amount of backlash may exceed the length K ₀ between them. Therefore, in order to avoid such a problem, the shape and size of the second insertion hole 72a shown in FIG. 5 are set. Specifically, the shape of the second insertion hole 72a is determined by the outdoor operation. The shaft 52 is set to have the same shape as the outer peripheral end of the room-side end of the room. Regarding the size of the second insertion hole 72a, the radial length of the second insertion hole 72a is the radial direction of the outer peripheral end. is set to the length K by ₁ minute longer becomes the size of the gap than the length of. With this setting, even when the outdoor operation shaft 52 has the operation shaft main body 52a, the first connection portion 52b, and the second connection portion 52c, the outdoor through hole 41a is exposed to the outside in the second insertion hole 72a. Assuring when attaching the outdoor operation shaft 52 to the locking device main body 51 can be ensured while preventing the exposure, the workability of the locking device 50 can be secured while further ensuring safety when using the door 1. Can be further maintained.

(Configuration-Locking device mounting structure-Third side portion of rattling suppression portion)
The third side portion 73 is a side portion for connecting the first side portion 71 and the second side portion 72, and as shown in FIGS. 3 and 5, the first side portion 71 and the second side portion 72. Between each other and approximately horizontally.

  The rattling suppression unit 70 configured in this way can be manufactured by any method or material. For example, the first side portion 71 and the second side portion 72 can be formed by bending a steel plate-like body. , And the third side portion 73 may be integrally formed, and the first insertion hole 71a and the second insertion hole 72a may be drilled at any time before or after the bending.

  With the mounting structure of the locking device 50 as described above, it is possible to reliably prevent the outdoor through hole 41a of the outdoor surface material 41 from being exposed to the outside. Therefore, since it is possible to prevent the user's finger from being inserted into the outdoor through hole 41a exposed to the outside, safety during use of the door 1 can be ensured and design of the door 1 can be maintained.

(About the action of the locking device mounting structure)
Then, the effect | action of the attachment structure of the locking device 50 comprised in this way is demonstrated.

That is, when the outdoor operation shaft 52 of the locking device 50 is attached to the locking device main body 51 of the locking device 50, the outdoor operation shaft 52 is attached to the outdoor surface of the outdoor surface material 41 by an operator (or user). Once inserted inside of the door body 20 through the through hole 41a, because of the gap length K ₁ are set based on the equation (3) from the above equation (1), rattle suppression unit 70 Since there is play between the second insertion hole 72a and the outdoor operation shaft 52 (specifically, the operation shaft main body 52a), the outdoor operation shaft 52 is inserted into the outdoor through hole 41a. However, it is possible to easily and accurately align the outdoor operation shaft 52 and the locking device main body 51. Therefore, the outdoor operation shaft 52 can be efficiently attached to the locking device main body 51, and the workability of the locking device 50 can be maintained.

In addition, when the locking device 50 is operated, if the user performs a locking operation via the outdoor operation shaft 52, the second insertion hole 72a of the backlash suppressing portion 70 and the outdoor operation shaft 52 are mutually connected. Since a gap is provided between them, the outdoor operation shaft 52 is rattled. In this case, the length between the fact that the gap length K ₁ are set based on the equation (3) from the above equation (1), the amount is above mutual backlash of the outdoor-side operation shaft 52 because it is limited in length below the K _0, it is possible to prevent the outdoor side through hole 41a of the outdoor side surface member 41 is exposed to the outside. Therefore, the designability of the door 1 can be maintained while ensuring the safety when the door 1 is used.

(Configuration-Other configurations)
In addition, the rattling suppression unit 70 can be configured with an arbitrary structure as much as possible.

  Specifically, in the embodiment, it has been described that the rattling suppression unit 70 is formed of a substantially plate-like body whose cross-sectional shape along the YZ plane is an inverted U shape. Not limited to. For example, as shown in FIG. 6, the rattling suppressing portion 70 is formed of a substantially plate-like body whose cross-sectional shape along the YZ plane is Z-shaped, and specifically, the third side portion 73. 1st side part 71 formed so that it might protrude upward from the edge part of the outdoor side of this room, and it was formed so that it might protrude downward from the indoor side edge part of the room in the 3rd side part 73 The second side portion 72 includes a second side portion 72 having a second insertion hole 72a, and a third side portion 73 for connecting the first side portion 71 and the second side portion 72. Good. With such a configuration, it is not necessary to provide the first insertion hole 71a in the first side portion 71, so that the trouble of processing the first insertion hole 71a can be omitted.

  Moreover, in embodiment, although the rattling suppression part 70 was demonstrated with respect to the outdoor surface material 41, it was not restricted to this. For example, the rattling suppression unit 70 may be fixed to the door frame 30. In this case, for example, as shown in FIG. 7, the rattling suppression unit 70 is formed of a substantially plate-like body having a L-shaped cross-section along the XY plane. It is the 1st side part 71 provided so as to oppose the door-end side longitudinal force bone 32 of the door frame 30, Comprising: The 1st for fixing with respect to the door-end side longitudinal force bone 32 by a fixing tool or welding etc. A second side portion 72 formed so as to protrude from a side portion 71 and an indoor side end portion of the room in the first side portion 71 toward the door butt side, and has a second insertion hole 72a. A side portion 72 may be provided. With such a configuration, the rattling suppression unit 70 can be stably fixed as compared to the case where the rattling suppression unit 70 is fixed to the outdoor surface material 41. In addition, the processing accuracy of the door-side longitudinal force bone 32 is relatively higher than the processing accuracy of the outdoor surface material 41, and the size of the outdoor surface material 41 is the size of the backlash suppressing portion 70 (or the door tip). Because the processing accuracy of the rattling suppressing portion 70 (or the processing accuracy of the door-end side vertical bone 32) is relatively higher than that of the outdoor surface material 41. By directly attaching the rattling suppression unit 70 to the door-end side longitudinal bone 32 to which the locking device main body 51 is attached, the rattling suppression unit 70 can be accurately aligned. Therefore, it becomes possible to improve the installation property of the rattling suppression part 70.

  Moreover, in embodiment, although the rattling suppression part 70 demonstrated that it was formed with the thin plate-shaped object, it is not restricted to this. For example, as shown in FIG. 8, the rattling suppressing portion 70 may be formed of a thick plate-like body. In this case, the size of the second insertion hole 72a is set to be substantially the same size with respect to the thickness direction (front-rear direction) of the second side portion 72, as shown in FIG. However, it is not limited to this. For example, as shown in FIG. 9, you may set so that it may become large from the side surface of the locking device main body 51 side among the side surfaces of the 2nd side part 72 to the side surface of the outdoor surface material 41 side. With this setting, the outdoor operation shaft 52 can be easily attached to the locking device main body 51, and the workability of the locking device 50 can be maintained.

(Effect of embodiment)
As described above, according to the embodiment, by inserting the outdoor operation shaft 52 into the second insertion hole 72a, the outdoor operation shaft 52 is covered with the outdoor through hole 41a. Therefore, the outdoor through hole 41a can be reliably prevented from being exposed to the outside. Therefore, since it is possible to prevent the user's finger from being inserted into the outdoor through hole 41a exposed to the outside, safety during use of the door 1 can be ensured and design of the door 1 can be maintained.

Further, since the length of the gap between the second insertion hole 72a and the outdoor operation shaft 52 is set so as to satisfy the following expression (3) from the following expression (1), in the second insertion hole 72a, While preventing the outdoor through-hole 41a from being exposed to the outside, it is possible to secure a play (gap) when the outdoor operation shaft 52 is attached to the locking device main body 51, so that safety during use of the door 1 is ensured. While ensuring, it becomes possible to maintain the workability of the locking device 50.

In addition, since the size of the second insertion hole 72a of the rattling suppressing portion 70 is set so as to satisfy the following formula (4) and the following formula (5), the outdoor operation shaft 52 includes the operation shaft main body 52a, the first Even when the first connecting portion 52b and the second connecting portion 52c are provided, the outdoor operation shaft 52 is attached to the locking device main body 51 while preventing the outdoor through hole 41a from being exposed to the outside in the second insertion hole 72a. Since it can ensure the play at the time of attachment, the workability | operativity of the locking device 50 can be maintained further, ensuring the safety | security at the time of use of the door 1 further.

And a hinge portion.

(About locking device)
In the above embodiment, the operation shaft main body of the outdoor operation shaft 52 (or the indoor operation shaft 54) has been described as being formed of a cylindrical body, but the present invention is not limited to this. For example, it may be formed of an elliptical cylindrical body having an elliptical cross-sectional shape or a polygonal cylindrical body having a polygonal cross-sectional shape. In this case, the shape of the second insertion hole 72 a may be set to a shape corresponding to the cross-sectional shape of the outdoor operation shaft 52.

May be. Thereby, the backlash amount of the outdoor operation shaft 52 can be reduced while securing the play when the outdoor operation shaft 52 is attached to the locking device main body 51.

(About rattling control part)
In the above-described embodiment, it has been described that the backlash suppressing portion 70 for suppressing the backlash of the outdoor operation shaft 52 is provided. However, the present invention is not limited to this. The rattling suppression part 70 for suppressing may be provided. Alternatively, when the length of the outdoor operation shaft 52 in the axial direction is shorter than the length of the indoor operation shaft 54 in the axial direction, the backlash suppressing portion 70 of the outdoor operation shaft 52 is omitted and the indoor operation is performed. Only the rattling suppression part 70 of the shaft 54 may be provided.

For example, the second insertion hole 72a may be provided so that the center point of the second insertion hole 72a is not collinear with the center point of the outdoor through hole 41a (the second insertion hole 72a in FIGS. 6 to 10 is also included). The same shall apply).

  Moreover, although the said embodiment demonstrated that the 1st side part 71 was provided so that it might contact | abut only the outdoor surface material 41, it is not restricted to this.

You may provide the 4th side part 74 formed so that it might protrude toward the downward direction from. In this case, the shape and the size of the second insertion hole 72a of the second side portion 72 are the length A ₁ = B ₁ + X in the left-right direction of the second insertion hole 72a, and the length in the vertical direction of the second insertion hole 72a. The rectangular shape of A ₂ = B ₂ + X is set, and the shape and size of the third insertion hole 74a formed in the fourth side portion 74 is set to the length A _{3 of} the third insertion hole 74a in the left-right direction. B ₂ + Y (here, “Y” means a value slightly larger than X), even if the vertical length of the second insertion hole 72a is set to A ₄ = B ₁ + Y. Good. Alternatively, without providing the fourth side portion 74, the shape and size of the first insertion hole 71a of the backlash suppressing portion 70 in FIG. 3 are simply the same as (or slightly the shape and size of the third insertion hole 74a). It may be set to a large size). With such a configuration, it is possible to suppress rattling of the outdoor operation shaft 52 in substantially the same manner as the rattling suppression unit 70 of FIG. In such a configuration, when the outdoor operation shaft 52 is attached to the locking device body 51, for example, the outdoor operation shaft 52 shown in FIG. 4 is 90 degrees around the rotation axis along the front-rear direction. After being inserted into the third insertion hole 74a in a rotated state, and then returned to the state before being rotated and then inserted into the second insertion hole 72a, the outdoor operation shaft 52 is inserted into the locking device body in the state before the rotation. 51 may be connected. Further, such a rattling suppressing portion 70 can be manufactured by an arbitrary method or material. For example, first, the first side portion 71 and the third side portion are formed by bending a steel plate-like body. A part of 73 is integrally formed, and another part of the second side part 72, the third side part 73, and the fourth side part 74 are integrally formed. And at any time before and after the bending, the plate-like body including the first side portion 71 and the plate-like body including the second side portion 72 are connected by welding or the like, and the first insertion hole 71a, You may manufacture by drilling the 2nd penetration hole 72a and the 3rd penetration hole 74a. Or it is not restricted to this, The 1st side part 71, the 2nd side part 72, the 3rd side part 73, the 4th side part 74, the 1st penetration hole 71a, the 2nd penetration by a well-known casting method using a metal mold etc. The hole 72a and the third insertion hole 74a may be integrally formed.
