Description

[Title of Invention] FITTING FRAME

[Technical Field]

[0001] The present invention relates to a fitting frame provided on the periphery of a fitting main body such as an entry (door).

[Background Art]

[0002] Conventionally, as disclosed in PTL 1, for example, this type of invention may be a fitting frame that includes a vertical frame main body having, on an upper end thereof, an opening part that communicates with an internal space, a horizontal frame that is connected to the upper end side of the vertical frame main body so as to extend in a horizontal direction, a connecting tool welded to an end part side of the vertical frame main body, and a screw for fixing the horizontal frame to the vertical frame main body and the connecting tool. When this type of fitting frame is mounted on an opening part inner edge of a skeleton of a building or the like, a part that slightly projects toward the front side from the skeleton wall surface is secured on the vertical frame main body and the horizontal frame. The projecting dimension of this part is sometimes referred to as the clearance or the clearance dimension. Hence, in a state where the fitting frame is mounted on the opening part inner edge of the skeleton wall surface, a part of the opening part at the upper end of the vertical frame main body may be exposed to the outside of the skeleton wall surface in order to secure the clearance dimension. In this case, foreign matter, pests, and so on may enter through the exposed opening part, or a worker or the like may touch the opening part. Therefore, in the fitting frame of PTL 1, a separate, rectangular frame-shaped lid member is fitted to the opening part at the upper end of the vertical frame main body and fixed by welding or the like.

Here, the wording "the member having the other" refers to one of the vertical frame member and the upper frame member and the other member with respect to one of the fitting part and the fitted part. In other words, when "one of the fitting part and the fitted part" refers to the fitting part, for example, the other is the fitted part, and the member having the other (the fitted part) is the upper frame member. Conversely, when "one of the fitting part and the fitted part" refers to the fitted part, for example, the other is the fitting part, and the member having the other (the fitting part) is the vertical frame member.

[0011] As a fourth feature, the vertical frame member includes a frame inside plate part that forms a frame inside surface extending in the vertical direction, and width plate parts that extend toward the frame outside in the width direction respectively from one end side and the other end side, in the depth direction, of the frame inside plate part, the upper frame member includes a frame inside plate part that forms a frame inside surface extending in the width direction, upward plate parts that respectively extend upward from one end side and the other end side, in the depth direction, of the frame inside plate part, and inward plate parts that project inward so as to face each other from the upper end side of the upward plate part on the one end side and the upper end side of the upward plate part on the other end side, a recessed notched part that opens upward is provided on an upper end side of the frame inside plate part of the vertical frame member such that the fitting part is formed to protrude to each of the two sides of the notched part, and the fitted part is formed in a slit form on both depth direction sides of the upper frame member so as to extend over the frame inside plate part, the upward plate part, and the inward plate part (see Fig. 3).

[0012] As a fifth feature, the closing part is formed by extending the inward plate part of the upper frame member to the frame outside (see Fig. 3).

[0013] As a sixth feature, a small notched part is provided in a lower side edge of the notched part by partially notching the lower side edge, and a projection part that is fitted to the small notched part is provided on the frame inside plate part of the upper frame member (see Fig. 3).

[0014] A seventh feature is a feature in which a projection part that projects toward the frame inside in the vertical direction is provided on the frame inside plate part of the vertical frame member, and a notched part that is fitted to the projection part of the vertical frame member is provided in the frame inside plate part of the upper side member (see Figs. 6 and 7).

[0015]

<Specific embodiment> Next, a specific embodiment having the above features will be described in detail on the basis of the figures. In the following description, the "width direction" denotes a horizontal width direction of the fitting frame (in Fig. 1, the left-right direction). Further, the "depth direction" denotes a thickness direction of the fitting frame, which is substantially orthogonal to the "width direction". Further, the "frame inside" denotes the inside of the fitting frame, and the "frame outside" denotes the outside of the fitting frame.

[0016] Fig. 1 shows an example of a fitting including a fitting frame according to the present invention. This fitting 1 includes a fitting main body A capable of opening/closing operations, and a fitting frame B that surrounds the fitting main body A in a rectangular frame shape, the fitting frame B being fitted to an opening part inner edge of a wall on a skeleton of a building or the like.

[0017] According to the example in the figure, the fitting main body A is a substantially rectangular plate-shaped entry (door). One end side of the fitting main body A in a door width direction thereof is supported to be free to rotate via a hinge al by one vertical frame member 10 of the fitting frame B. In the figure, a reference symbol a2 denotes a knob used for the opening/closing operations and so on.

[0018] The fitting frame B includes the vertical frame member 10, which extends in a vertical direction, an upper frame member 20 that is connected substantially at a right angle to an upper end side of the vertical frame member 10 so as to extend in the width direction, and a lower frame member 30 that is connected substantially at a right angle to a lower end side of the vertical frame member 10 so as to extend in the width direction.

[0019] Two vertical frame members 10 are provided with an interval therebetween in the horizontal width direction. Each vertical frame member 10 has a substantially C-shaped profile that extends in the vertical direction, and an upwardly oriented opening part 10a that communicates with a space inside the vertical frame member 10 is provided in an upper end thereof. The opening part 10a is closed by a closing part 23a of an upper frame member 20, to be described below.

[0020] More specifically, each vertical frame member 10 includes a frame inside plate part 11 that extends continuously in the vertical direction so as to form a frame inside surface, width plate parts 12 and 12 that extend toward the frame outside in the width direction respectively from one end side and the other end side, in the depth direction, of the frame inside plate part 11, and inward plate parts 13 and 13 that project toward the inside so as to face each other from a frame outside end part of the width plate part 12 on the one end side and a frame outside end part of the width plate part 12 on the other end side (see Figs. 3 and 4).

[0021] The frame inside plate part 11 includes a projection part 11a that projects toward the frame inside near the center in the depth direction. The projection part 11a has a convex latitudinal profile that extends continuously in the vertical direction. The projection part 11a functions as a door stopper part that receives a surface of the fitting main body A on a closing direction side when the fitting main body A is fully closed from an open state.

[0022] Further, a fitting part 14a that is fitted to a fitted part 20a of the upper frame member 20 so as not to move relative thereto in the width direction and the depth direction is provided on the upper end side of the frame inside plate part 11.

[0023] The fitting part 14a is formed by providing an upwardly open and downwardly recessed notched part 14 on a depth direction center side of the upper end side of the frame inside plate part 11 of the vertical frame member 10. In other words, an edge part on each of the two sides of the notched part 14 functions as the fitting part 14a. Each of the fitting parts 14a is formed in a tabular protruding form so as to intersect the upper frame member 20 substantially at a right angle.

[0024] Further, a small notched part 14b is provided on a lower side edge of the notched part 14 by notching this edge on the depth direction center side. More specifically, the small notched part 14b is formed in a position corresponding to the projection part 11a by notching the lower side edge part of the notched part 14 into a recessed shape and also notching the upper end side of the projection part 11a.

[0025]

The notched part 14, the fitting parts 14a, the small notched part 14b, and so on, configured as described above, are also provided on the lower end side of the frame inside plate part 11 in vertical symmetry.

[0026] The width plate parts 12 and 12 on both sides are formed in tabular form so as to respectively be substantially orthogonal to the frame inside plate part 11, and extend continuously along the entire length of the vertical frame member 10.

[0027] Further, the inward plate parts 13 and13 on both sides are formed in a tabular protruding form so as to face each other in the depth direction with an interval therebetween. A plurality of fixing pieces 15 are fixed between the inward plate parts 13 and 13 at appropriate intervals in the vertical direction (see Fig. 3). The fixing pieces 15 are fixed to a fixing member (an anchor or the like), not shown in the figures, on the skeleton opening part side.

[0028] The vertical frame member 10 having the above configuration is formed by bending a tabular metal sheet material, and the notched part 14 is formed prior to the bending process by pressing or the like.

[0029] Further, the upper frame member 20 includes a frame inside plate part 21 that extends continuously in the width direction so as to form a downwardly oriented surface on the frame inside, upward plate parts 22 and 22 that respectively extend upward from one end side and the other end side, in the depth direction, of the frame inside plate part 21, and inward plate parts 23 and 23 that project inward so as to face each other from the upper end side of the upward plate part 22 on the one end side and the upper end side of the upward plate part 22 on the other end side, the frame inside plate part 21, the upward plate parts 22 and 22, and the inward plate parts 23 and 23 being formed integrally (see Figs. 2, 3 and 5).

[0030] The frame inside plate part 21 includes a downwardly projecting projection part 21a that serves as the frame inside near the depth direction center. The projection part 21a has a convex longitudinal profile that extends continuously in the width direction over the entire length of the upper frame member 20. The projection part 21a is fitted to the small notched part 14b of the vertical frame member 10 on a width direction end part side (see Fig. 3). In other words, the projection part 21a, which extends in a horizontal direction, is configured to have a horizontally inserted form that either contacts or is in proximity to an upper end part Hal of the projection part 11a extending in the vertical direction. The projection part 21a functions as a door stopper part that receives the surface of the fitting main body A on the closing direction side (more specifically, an upper end side part of this surface) when the fitting main body A is fully closed from an open state.

[0031] The upward plate parts 22 and 22 on both sides are each formed in tabular form so as to be substantially orthogonal to the frame inside plate part 21, and extend continuously in the width direction over the entire length of the upper frame member 20.

[0032] Further, the inward plate parts 23 and 23 on both sides are formed in a tabular protruding form so as to face each other in the depth direction with an interval therebetween, and extend continuously in the width direction over the entire length of the upper frame member 20. A plurality of fixing pieces 25 are fixed between the inward plate parts 23 and 23 by welding or the like at appropriate intervals in the width direction. The fixing pieces 25 are fixed to a fixing member (an anchor or the like), not shown in the figures, on the skeleton opening part side.

[0033] The fitted part 20a, which is fitted to the fitting part 14a of the vertical frame member 10 so as not to move relative thereto in the width direction and the depth direction, and the closing part 23a, which closes the opening part 10a of the vertical frame member 10 on the frame outside of the fitted part 20a, are each provided on one end side and the other end side of the upper frame member 20 having the above configuration.

[0034] The fitted part 20a is formed to extend over the frame inside plate part 21, the upward plate part 22, and the closing part 23a on both depth direction sides of the upper frame member 20 in the shape of a slit (or a slot) to which the protruding fitting part 14a is fitted. In other words, the fitted part 20a is formed in a part having an inverted C-shaped longitudinal profile extending over the frame inside plate part 21, the upward plate part 22, and the inward plate part 23 so as to vertically penetrate the frame inside plate part 21, the upward plate part 22, and the inward plate part 23 on the depth direction end side thereof.

[0035] The closing part 23a is formed by extending the part of each inward plate part 23 other than the fitted part 20a in tabular form to the frame outside of the fitted part a. The closing part 23a is in proximity to or in contact with the upper end edge of the vertical frame member 10. More specifically, an upper surface of the closing part 23a is positioned substantially flush with the upper end part of the vertical frame member 10. A protruding end part on the frame outside of the closing part 23a is positioned in proximity to or in contact with an inner surface of the inward plate part 13 of the vertical frame member 10 (see Fig. 2).

[0036] Further, on the upper frame member 20, a lower side part of the closing part 23a is a part formed by extending the frame inside plate part 21 and the upward plate part 22 to the frame outside, and this part is positioned within the opening part 10a of the vertical frame member 10. Note that in a different example to the example in the figures, the part positioned within the opening part 10a may be partially or entirely omitted.

[0037] The upper frame member 20 having the above configuration is formed by bending a tabular metal sheet material, and the penetrating slit-shaped fitted part 20a and so on are formed prior to the bending process by pressing or the like.

[0038] The vertical frame member 10 and the upper frame member 20 having the above configurations are integrally connected via a connecting tool 40 (see Fig. 4) provided in an inner corner-shaped part therebetween. The connecting tool 40 is an angled member having a substantially L-shaped profile, one piece of which is fixed to the vertical frame member 10 by welding or the like. When connecting the vertical frame member 10 and the upper frame member , the other piece of the connecting tool 40 is connected and fixed to the upper frame member 20 by a fixing tool such as a screw. A reference symbol 20b in Fig. 5 is a hole for inserting the fixing tool.

[0039] Note that as another example, the other piece of the connecting tool 40 may be formed so as to be connected to the upper frame member 20 by welding.

As further examples, the connecting tool 40 may be omitted, and the vertical frame member 10 may be directly connected to the upper frame member 20 by a fixing tool or the vertical frame member 10 may be directly connected to the upper frame member 20 by welding.

[0040] Further, a lower frame member 30 is a member that is vertically symmetrical to the upper frame member 20, and the connection structure by which the lower frame member 30 is connected to the vertical frame member 10 is also vertically symmetrical. The lower frame member 30 may have a different configuration to that described above, or may be omitted.

[0041] Next, featured actions and effects of the fitting 1 will be described in detail. According to the above configurations, the connecting part of the vertical frame member 10 and the upper frame member 20 is positioned with a high degree of precision by fitting together the fitting parts 14a and the fitted parts 20a. Therefore, an operation for connecting and fixing the vertical frame member 10 to the upper frame member 20 by welding, screwing, or the like can be simplified, and as a result, as well as favorable on-site manufacturing operability, favorable assembly operability on-site or the like using the knockdown system is also achieved.

[0042] Further, by fitting the fitted parts 20a of the upper frame member 20 to the fitting parts 14a of the vertical frame member 10, the opening part 10a at the upper end of the vertical frame member 10 can be closed by the closing part 23a. Hence, when the fitting frame B is mounted on the skeleton opening part, the upper end of the vertical frame member 10 does not remain open in accordance with the clearance dimension part, and as a result, foreign matter, pests, and the like do not enter through the opening, workers or the like do not touch the opening, and so on.

[0043] <Modified Examples> Note that in the fitting frame B of the embodiment described above, the structure of the left and right vertical frame members 10 and 10 may be applied to the upper frame member, and the structure of the upper frame member 20 may be applied to the left and right vertical frame members. In other words, the fitting frame B having the above configuration may be rotated horizontally by a 90-degree angle so as to appropriately adjust the longitudinal and latitudinal dimensions. In this configuration, the vertical frame member 10 having the above configuration is referred to as the upper frame member (or the horizontal frame member), and the upper frame member 20 having the above configuration is referred to as the vertical frame member. Similarly in this case, the end part side of the upper frame member having the structure of the vertical frame member 10 can be caused to function as the closing part. In other words, the opening in the upper end of the vertical frame member having the structure of the upper frame member 20 can be closed by the end part side (the closing part) of the upper frame member having the structure of the vertical frame member 10.

[0044] Further, in the fitting frame B according to the above embodiment, the projection part 11a (the door stopper part) of the vertical frame member 10 and the projection part 21a (the door stopper part) of the upper frame member 20 are configured to have the horizontally inserted form described above (see Fig. 3), but as another example, the two projections parts (door stopper parts) may be configured to have a vertically inserted form such as that of a fitting frame B' shown in Figs. 6 and 7.

[0045] More specifically, in the fitting frame B', the frame inside plate part 11 of the vertical frame member 10 includes a projection part 11a'that projects toward the frame inside in the vertical direction, and an upper end part 11al'of the projection part 11a'is flush with the lower side inner edge of the notched part 14 (see Fig. 7). In other words, the vertical frame member 10 of the fitting frame B'is formed by omitting the small notched part 14b from the vertical frame member 10 of the fitting frame B described above (see Fig. 3) so that the upper end part 11a' of the projection part 11a'is flush with the lower side inner edge of the notched part 14.

[0046] Further, in the fitting frame B', a notched part 21b' that is fitted to the projection part 11a' of the vertical frame member 10 is provided on the frame inside plate part 21 of the upper frame member 20. In other words, the upper frame member 20 of the fitting frame B'is formed by providing the notched part 21b'on the upper frame member 20 of the fitting frame B described above (see Fig. 3).

[0047] The projection part 11a' of the vertical frame member 10 is configured in a vertically inserted form that is fitted to the notched part 21b' so as to penetrate the projection part 21a of the upper frame member 20 upwardly (see Fig. 6).

[0048]

Thus, according to the fitting frame B' shown in Figs. 6 and 7, substantially similarly to the fitting frame B described above, favorable assembly operability using the knockdown system is achieved on-site and so on, and as a result, the formation of an opening in the upper end of the vertical frame member 10 in accordance with the clearance dimension part when the fitting frame B'is mounted on the skeleton opening part can be prevented.

[0049] Further, the vertical frame member 10 and the upper frame member 20 of the embodiment described above have substantially C-shaped profiles, but as other examples, the vertical frame member 10 and the upper frame member 20 may be formed to have profiles that are inverted C-shaped, square, circular, or another shape.

[0050] Furthermore, according to the embodiment described above, the fitting frame B having the above configuration is applied to a frame member of an entry (door), but as other examples, the fitting frame B may be applied to a frame member (or a central pillar or the like) of an entry, a sliding door, a balance door, a waterproof door, a window sash, a screen door, a partition, or a shutter device.

[0051] Moreover, according to the embodiment described above, the fitting frame B is configured in the form of a four-sided framework, but as another example, the fitting frame B may be configured in the form of a three-sided framework from which the lower frame member 30 is omitted. In a further example, the fitting frame B may be applied to a structure in which, in a fitting frame having a mullion between left and right vertical frame members, an opening part at the upper end of the mullion is closed.

[0052] Furthermore, the present invention is not limited to the embodiment described above and may be modified as appropriate within a scope that does not alter the spirit of the present invention.
