At the same time, it is possible to reduce costs and labor for manufacturing the lower suspension frame member 34.

  The plurality of frame members 35 arranged in this way are connected to each other by a fitting structure. That is, among the plurality of frame members 35, one of the two frame members 35 that are orthogonal to each other so that one frame member 35 can be fitted to the other frame member 35. At the end of the frame member 35, only one recess is formed to open outward in the longitudinal direction of the one frame member 35, and at the end of the other frame member 35, only one protrusion is formed. . Then, these two frame members 35 are connected to each other by fitting the convex portion into the concave portion.

  Hereinafter, the fitting structure will be described more specifically. FIG. 8 is a perspective view showing a fixed state of the upper suspension frame member 33 and the door-end side vertical frame member 31. As shown in FIG. 8, first, the fitting structure related to the upper suspension frame member 33 will be described. As shown in FIG. 8, a concave portion 33 c is formed by cutting out the left end portion of the center piece 33 a at the left end portion in the longitudinal direction of the upper suspension frame member 33, and the longitudinal direction of the door-end side vertical frame member 31 is formed. A convex portion 31c is formed at the upper end portion of the pair of side pieces 31b by notching the upper end portions of the pair of side pieces 31b (more precisely, by further notching the outdoor side end portion and the indoor side end portion of the center piece 31a). Has been. Then, by fitting the concave portions 33c and the convex portions 31c with each other so that the convex portions 31c are inserted into the concave portions 33c, the left end portion in the longitudinal direction of the upper suspension frame material 33 and the door-end side vertical frame material The upper end portions in the longitudinal direction of 31 are fixed to each other without being welded to each other as in the prior art. In particular, in the present embodiment, among the pair of side pieces 31b of the door-end side vertical frame member 31, the outdoor-side side piece 31b faces the door-end side vertical frame 11 rather than the indoor-side side piece 31b. It is formed so as to extend long, and in the state where the door body 20 is located at the fully closed position, the door-side vertical frame is brought into contact with the outdoor side surface of the door-side vertical frame 11. The gap between the material 31 and the door-end side vertical frame 11 is prevented from being exposed to the outside, and the design and crime prevention are improved.

  Further, the specific shapes of the concave portion 33c and the convex portion 31c are arbitrary as long as they can be fitted to each other. In the present embodiment, the convex shape of the door-end side vertical frame member 31 is used. By making the notch depth (vertical dimension) D1 for forming the portion 31c the same or less than the height (vertical dimension) of the side piece 33b of the upper suspension frame member 33 The upper end surface (end surface of the convex portion 31c) of the central piece 31a of the door-end side vertical frame member 31 and the upper side surface of the central piece 33a of the second portion 33h of the upper suspension frame member 33 are flush with each other. (It is the same for the specific shapes of a concave portion 33c and a convex portion 34c described later). For this reason, the indoor side surface material 41 and the outdoor side surface material 42 can be brought into close contact with these end surfaces and side surfaces.

  Moreover, in this Embodiment, the device for preventing the door-end side vertical frame material 31 falling off further toward the outer side of the door frame 30 is given. Specifically, as shown in FIG. 8, a pair of claw portions 33 j is provided in the recess 33 c of the upper suspension frame member 33. The pair of claw portions 33j are release prevention means for preventing the fitting of the upper suspension frame member 33 and the door-end side vertical frame member 31 from being released. FIG. 9 is a diagram showing details of the claw portion 33j, and is a plan view of the main part of FIG. As shown in FIG. 9, one claw portion 33j is disposed so as to protrude inward from one of a pair of side wall portions in the recess 33c, and the other claw portion 33j is a pair of side wall portions in the recess 33c. It arrange | positions so that it may protrude toward the inner side from the other. That is, the pair of claw portions 33j are disposed so as to sandwich the convex portion 31c of the door-end side vertical frame member 31 from both the outdoor side and the indoor side. In particular, the length L7 from the pair of claw portions 33j to the bottom wall portion of the concave portion 33c is set to be substantially the same as the thickness of the convex portion 31c, whereby the pair of claw portions 33j And the bottom wall portion of the concave portion 33c hold the convex portion 31c with almost no gap, and the upper suspension frame member 33 is prevented from inadvertently swinging (see FIG. In FIG. 9, the convex portion 31c is indicated by a two-dot chain line for convenience of illustration). The specific overhanging length and shape of the pair of claw portions 33j are arbitrary. For example, when the convex portion 31c is inserted from the opening side of the concave portion 33c, the convex portion 31c is inserted over the pair of claw portions 33j. Although it is relatively easy to do so, the convex portion 31c has a planar triangular shape as shown in FIG. 9 so that it is relatively difficult to get over the pair of claws 33j and return to the opposite direction. In addition, although the specific formation method of a pair of nail | claw part 33j is arbitrary, when punching and forming the recessed part 33c in the upper side suspension frame material 33 in this Embodiment, it punches also about a pair of nail | claw part 33j simultaneously. The pair of claw portions 33j are formed integrally with the upper suspension frame member 33.

  FIG. 10 is a perspective view showing a fixed state of the upper suspension frame member 33 and the door butt side vertical frame member 32. As shown in FIG. 10, the right end portion of the pair of side pieces 33b is cut out at the right end portion in the longitudinal direction of the upper suspension frame member 33 (more precisely, the outdoor side end portion of the center piece 33a). Further, a convex portion 33i is formed (by also cutting out the indoor side end portion), and a concave portion 32e is formed at the upper end portion in the longitudinal direction of the door bottom side vertical frame member 32 by cutting out the upper end portion of the center piece 32a. Is formed. Then, by fitting the concave portion 32e and the convex portion 33i to each other so that the convex portion 33i is inserted into the concave portion 32e, the right end portion in the longitudinal direction of the upper suspension frame member 33 and the door butt side vertical frame member The upper end portions in the longitudinal direction of 32 are fixed to each other without being welded to each other as in the prior art. In this case, more specifically, regarding the positional relationship between the upper suspension frame member 33 and the door butt side vertical frame member 32, specifically, at least a part of the upper pivot hinge (for example, the upper pivot hinge of the upper pivot hinge). In order to form an accommodation area 70 for accommodating the lower plate and all or part of the support portion), the recess 32e of the door-side vertical frame member 32 and the protrusion 33i of the upper suspension frame member 33 are mutually connected. In the fitted state, the horizontal surface (the upper surface of the first portion 33 f) on the outer side of the upper suspension frame member 33 with respect to the end surface of the upper end portion of the side piece 32 b of the door butt side vertical frame member 32 is placed on the door frame 30. It is located on the inner side (lower side). With such a configuration, the first portion 33f is disposed at a position away from the second portion 33h with respect to the upper lateral frame 13, and the first main body 33f is in the state where the door body 20 is positioned at the fully closed position. The accommodation region 70 described above is formed between the portion 33f and the upper horizontal frame 13. As a result, the central piece 33a of the second portion 33h of the upper suspension frame member 33 and the indoor side surface material 41 and the outdoor side surface material 42 are brought into close contact with each other through the rivets 44 while the accommodation area 70 is secured. Therefore, it is not necessary to provide a fixing plate for fixing the surface material and the suspension frame material as in the conventional suspension frame material. Thereby, while being able to reduce the number of parts of the upper suspension frame material 33, the operation | work which fixes a component to the upper suspension frame material 33 can be abbreviate | omitted, and the cost and labor which manufacture the upper suspension frame material 33 are reduced. It becomes possible.

  In the present embodiment, the possibility that an upward or downward force is applied to the upper suspension frame member 33 increases, and the upper suspension frame member 33 falls off toward the outside of the door frame 30. The potential increases. For this reason, in this Embodiment, the device for preventing such omission more firmly is given. Specifically, as shown in FIG. 10, a pair of claw portions 32 f is provided in the concave portion 32 e at the upper end of the door-side vertical frame member 32. The pair of claw portions 32f are release prevention means for preventing the fitting of the upper suspension frame member 33 and the door butt side vertical frame member 32 from being released. The one claw portion 32f is arranged so as to protrude inward from one of the pair of side wall portions in the recess 32e, and the other claw portion 32f is extended inward from the other of the pair of side wall portions in the recess 32e. It is arranged to put out. That is, the pair of claw portions 32f are arranged so as to sandwich the convex portion 33i of the upper suspension frame member 33 from both the outdoor side and the indoor side. In particular, the length L8 from the pair of claw portions 32f to the bottom wall portion of the concave portion 32e is set to be substantially the same as the thickness of the convex portion 33i, whereby the pair of claw portions 32f And the bottom wall portion of the recess 32e hold the projection 33i with almost no gap, thereby preventing the upper suspension frame member 33 from swinging carelessly. The specific overhanging length of the pair of claw portions 32f is arbitrary. For example, when the convex portion 33i is inserted from the open side of the concave portion 32e, the convex portion 33i is inserted over the pair of claw portions 32f. Although it is comparatively easy, it is a plane triangle like the one shown in FIG. 9 so that it is relatively difficult to get the convex portion 33i over the pair of claw portions 32f and return it in the opposite direction. In addition, although the specific formation method of a pair of nail | claw part 32f is arbitrary, when punching and forming the recessed part 32e in the door butt side vertical frame material 32 in this Embodiment, it is also about a pair of nail | claw part 32f. The pair of claw portions 32f are integrally formed with the door butt side vertical frame member 32 at the same time.

  Further, the fitting structure related to the upper suspension frame member 33 is similarly applied to the fitting structure related to the lower suspension frame member 34. That is, as shown in FIG. 5, a recess 34 c is formed at the left end portion in the longitudinal direction of the lower suspension frame member 34 by cutting out the left end portion of the center piece 34 a, and the door-end side vertical frame member 31 is formed. The lower end of the pair of side pieces 31b is cut out at the lower end in the longitudinal direction (more precisely, by further cutting out the outdoor side end and the indoor side end of the center piece 31a). 31c is formed. Then, by fitting these concave portions 34c and convex portions 31c to each other so that the convex portions 31c are inserted into the concave portions 34c, the left end portion in the longitudinal direction of these lower suspension frame members 34 and the door-end side vertical frame The lower end part of the longitudinal direction of the material 31 is mutually fixed, without welding mutually. Further, the above-described release prevention structure between the upper suspension frame member 33 and the door-end side vertical frame member 31 is similarly applied to the fitting of the lower suspension frame member 34 and the door-end side vertical frame member 31. . That is, a pair of claw portions (not shown) is provided in the concave portion 34 c of the lower suspension frame member 34. These pair of claw portions are release prevention means for preventing the fitting of the lower suspension frame member 34 and the door-end side vertical frame member 31 from being released. The one claw portion is arranged so as to project inward from one of the pair of side wall portions in the recess 34c, and the other claw portion is projected inward from the other of the pair of side wall portions in the recess 34c. Is arranged. That is, the pair of claw portions are arranged so as to sandwich the convex portion 31c of the door-end side vertical frame member 31 from both the outdoor side and the indoor side.

  Further, by cutting out the right end portion of the pair of side pieces 34b at the right end portion in the longitudinal direction of the lower suspension frame member 34 (more precisely, the outdoor side end portion and the indoor side end portion of the center piece 34a). A protrusion 34i is formed (by also cutting out), and a recess 32e is formed at the lower end in the longitudinal direction of the door butt side vertical frame member 32 by cutting out the lower end portion of the center piece 32a. Then, by fitting the concave portion 32e and the convex portion 34i with each other so that the convex portion 34i is inserted into the concave portion 32e, the right end portion in the longitudinal direction of the lower suspension frame member 34 and the door bottom side vertical frame The lower end portion in the longitudinal direction of the material 32 is fixed to each other without being welded to each other as in the prior art. In this case, more specifically, regarding the positional relationship between the lower suspension frame member 34 and the door sill side vertical frame member 32, specifically, at least a part of the lower pivot hinge on the door frame 30 (for example, the lower side In order to form an accommodation area 71 for accommodating the upper plate of the pivot hinge, all or a part of the support portion, etc., the recesses 32e of the door-side vertical frame member 32 and the protrusions of the lower suspension frame member 34 are formed. In a state in which the portions 34i are fitted to each other, a horizontal surface (a lower surface of the first portion 34f) outside the lower suspension frame material 34 with respect to the end surface of the lower end portion of the door bottom side vertical frame material 32 is connected to the door frame. It is located near the inner side (upward side) of 30. With such a configuration, an accommodation region 71 is formed between the first portion 34 f and the lower lateral frame 14 in a state where the door body 20 is positioned at the fully closed position. As a result, the central piece 34a of the second portion 34h of the lower suspension frame member 34 and the indoor side surface material 41 and the outdoor side surface material 42 are brought into close contact with each other through the rivet 45 while securing the accommodation area 71. Since they can be fixed in contact with each other, there is no need to provide a fixing plate for fixing the surface material and the suspension frame material as in the conventional suspension frame material. Thereby, the number of parts of the lower suspension frame member 34 can be reduced, and the manufacturing cost of the lower suspension frame member 34 can be reduced. The release prevention structure between the upper suspension frame member 33 and the door sill side vertical frame member 32 is similarly applied to the fitting of the lower suspension frame member 34 and the door sill side vertical frame member 32. That is, a pair of claw portions (not shown) is provided in the recess 32 e at the lower end of the door-side vertical frame member 32. These pair of claw portions are release prevention means for preventing the fitting of the lower suspension frame member 34 and the door butt side vertical frame member 32 from being released. The pair of claws are integrally formed with the door butt side vertical frame member 32, and one of the claws is disposed so as to project inward from one of the pair of side walls in the recess 32e, and the other The nail | claw part is arrange | positioned so that it may protrude toward the inner side from the other of a pair of side wall part in the recessed part 32e. That is, the pair of claws are arranged so as to sandwich the convex portion 34i of the lower suspension frame member 34 from both the outdoor side and the indoor side.

Each part is formed integrally with each other.

  The indoor-side surface material 41 and the outdoor-side surface material 42 formed in this way function as a decorative material that covers the door frame 30 and the core 50 so as not to be exposed from the outside, and a plurality of frames of the door frame 30. It also functions as a structural material that prevents the material 35 from falling off. Hereinafter, the fixing structure for fixing the plurality of frame members 35 of the door frame 30 including this point will be described in more detail.

(Configuration-Fixing structure for multiple frame materials of door frame)
First, the fixing structure of the door end side vertical frame member 31 will be described. As described above, the door-end side vertical frame member 31 fits the convex portion 31c of the door-end side vertical frame member 31 with the concave portion 33c of the upper suspension frame member 33 and the concave portion 34c of the lower suspension frame member 34. By doing so, it is connected to the upper suspension frame member 33 and the lower suspension frame member 34. In particular, as shown partially in FIG. 8, the convex portion 31 c is brought into contact with the upper suspension frame member 33 and the lower suspension frame member 34 by bringing the inner side (door bottom side) side surface of the projection 31 c into contact with each other.

In particular, as partially shown in FIG. 8, the inner (lower) surface of the pair of side pieces 33 b of the upper suspension frame member 33 is the outer side (upper side) of the pair of side pieces 31 b of the door-end side vertical frame member 31. ). Further, as partially shown in FIG. 10, the inner (lower) surface of the central piece 33 a of the upper suspension frame member 33 is set to the outer (upper) surface of the central piece 32 a of the door-side vertical frame member 32. It is in contact. As a result, the movement of the side piece 33b to the inside (lower side) is restricted, and the upper suspension frame member 33 is prevented from falling off toward the inside (lower side) of the door frame 30. In addition, the pair of claw portions 32f are arranged so as to sandwich the convex portion 33i of the upper suspension frame member 33 from both the outdoor side and the indoor side, and the indoor side surface material is provided on the outer side (upper side) of the upper suspension frame member 33. 41, and the upper side surface portion 42b of the outdoor side surface material 42 are arranged, the upper suspension frame material 33 is placed outside by the pair of claw portions 32f, the upper side surface portion 41b, and the upper side surface portion 42b. The movement to the (upper side) is restricted, and the upper suspension frame member 33 is prevented from dropping toward the outside (upper side) of the door frame 30. As described above, in the present embodiment, with respect to the upper suspension frame member 33 falling off from the door frame 30, the dropout with respect to the inner side (lower side) is the fitting structure between the concave portion 33 c and the convex portion 31 c and the convexity. While being prevented by the fitting structure of the part 33i and the recessed part 32e, falling off with respect to the outer side (upper side) is prevented by a pair of nail | claw part 32f, the indoor side surface material 41, and the outdoor side surface material 42.

  The fixing structure of the lower suspension frame member 34 is the same as the fixing structure of the upper suspension frame member 33 described above. That is, in the present embodiment, with respect to the lower suspension frame member 34 falling off from the door frame 30, the fitting structure of the recess 34c and the protrusion 31c, and the protrusion 34i and the recess 32e are prevented by the fitting structure, and the pair of claw portions (not shown), the indoor side surface material 41, and the outdoor side surface material 42 are prevented from falling off from the outside (lower side). ing.

(Manufacturing method of hanging frame material)
Then, the manufacturing method of the manufacturing method of the upper side suspension frame material 33 and the lower side suspension frame material 34 is demonstrated. However, since the upper suspension frame member 33 and the lower suspension frame member 34 can be configured by changing the folding direction, only the details of the configuration of the upper suspension frame member 33 will be described below. FIG. 11 is a diagram showing an outline of a method for manufacturing the upper suspension frame material, where (a) is a state before processing a steel plate-like body, (b) is a state after side pieces are bent, (c) is a state after bending a specific part in the longitudinal direction, and (d) is a view showing a state after punching out a recess or the like.

  First, as shown in FIG. 11A, a steel plate-like body is prepared, and as shown in FIG. 11B, a central piece 33a and a pair of side pieces orthogonal to the central piece 33a. From 33b, the steel plate-like body is bent and formed so that the cross-sectional shape of the cross-section orthogonal to the longitudinal direction of the plate-like body becomes a U shape.

  Next, as shown in FIG. 11 (c), the first portion 33f, the third portion 33g, and the second portion 33h are arranged side by side in this order so that the first portion of the steel plate-like body is formed.
