Description

The present invention relates to a fitting provided with a resin frame-shaped member in which a metal reinforcing material is arranged.

In recent years, fittings in which an opening frame fixed to the frame of a building and a shoji stile supported by the opening frame are made of resin have been used. When such resin fittings are used for window devices, door devices, etc., the heat insulating performance is improved, and it is also effective in preventing dew condensation.

However, the frame-shaped members such as the resin opening frame and the frame have higher temperature dependence and lower strength than the metal frame-shaped members such as aluminum. Therefore, the resin frame-shaped member may be deformed at high temperature or due to the weight of the shoji. Therefore, there is a configuration in which a metal reinforcing material is inserted into the hollow portion of the resin frame-shaped member to reinforce it (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2016-14202

When the reinforcing material is inserted into the hollow portion of the frame-shaped member as in the above-mentioned conventional technique, the hollow portion and the reinforcing material are used in order to absorb the variation in the manufacturing of the resin frame-shaped member and the metal reinforcing material. It is common practice to provide a certain amount of gap between the two. If this gap is made large, the risk of assembly failure due to interference when inserting the reinforcing material is reduced, and workability during manufacturing is improved. However, since the frame-shaped member and the reinforcing material are displaced from each other by the amount of the large gap, the reinforcing effect of the frame-shaped member by the reinforcing material is reduced. In particular, the extruded shape made of resin has a larger variation in shape than the extruded shape made of metal due to the manufacturing method and the characteristics of the material, and such a problem is likely to occur.

Further, in the resin frame-shaped member, for example, when fixing a metal part such as a hinge that opens and closes and supports the shoji, a metal reinforcing material serving as a back plate for screwing may be used. The reinforcing material in this case also needs to be able to be easily assembled to the frame-shaped member and at the same time to prevent misalignment and the like.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and provides a fitting capable of improving manufacturing efficiency and ensuring a reinforcing effect of a resin frame-shaped member by a reinforcing material. The purpose is to do.

The fitting according to the present invention is a fitting provided with a resin frame-shaped member in which a metal reinforcing member is arranged, and the reinforcing member is applied to a first inner surface which is an inner surface of the frame-shaped member. It is characterized by having a fastening surface that is tangently arranged and fastened and fixed to the first inner surface using a fastener, and a resistance applying portion that imparts resistance between the contact surface between the first inner surface and the fastening surface. And.

According to such a configuration, resistance is applied by the resistance applying portion between the contact surface between the fastening surface of the reinforcing member and the first inner surface of the frame-shaped member. This makes it possible to prevent misalignment of the reinforcing material fastened and fixed to the frame-shaped member. As a result, a certain amount of gap can be provided between the reinforcing material and the hollow portion or the concave portion where the reinforcing material is arranged in the frame-shaped member. Therefore, the work of inserting the reinforcing material into the frame-shaped member becomes easy, and the manufacturing efficiency is improved.

In the fitting according to the present invention, the resistance imparting portion may be composed of protrusions protruding from the fastening surface. Then, when the frame-shaped member and the reinforcing member are fastened and fixed by the fastener, the metal protrusions bite into the first inner surface made of resin. As a result, the reinforcing material is more firmly fixed to the frame-shaped member, and the displacement of the reinforcing material is more reliably prevented.

In the fitting according to the present invention, the fastening surface may be configured to have a recess around the fastening portion by the fastener. Then, the burr generated around the fastening portion at the time of fastening with the fastener can be discharged to the recess. Therefore, it is possible to prevent burrs from being sandwiched between the fastening surface and the first inner surface and making it impossible to obtain normal fastening strength and fastening posture. Further, by providing the concave portion, it is possible to prevent burrs remaining on the peripheral edge portion from being sandwiched between the fastening surface and the first inner surface when the hole portion for fastening the reinforcing member or the frame-shaped member is formed.

In the fitting according to the present invention, the reinforcing member is arranged at right angles to the fastening surface and the first inner surface of the frame-shaped member, which is arranged in contact with the first inner surface of the frame-shaped member. Is arranged on a third inner surface different from the first inner surface and the second inner surface of the frame-shaped member, which is arranged orthogonally to the fastening surface and a positioning portion which is arranged in contact with the second inner surface which is another inner surface. On the other hand, it has a gap facing surface which is arranged to face each other through a gap, and the resistance applying portion applies resistance in a direction from the positioning portion toward the gap facing surface between the first inner surface and the fastening surface. It may be a given configuration. Then, the reinforcing material can be easily and surely positioned and arranged at a predetermined position with respect to the frame-shaped member via the fastening surface and the positioning portion. Moreover, in this positioning state, the reinforcing material has a gap formed between the gap facing surface and the third inner surface. Therefore, it is easy to insert the reinforcing material into the hollow portion or the concave portion of the frame-shaped member, and the manufacturing efficiency is high.

In the fitting according to the present invention, the reinforcing material extends along the longitudinal direction of the frame-shaped member, and the fastening surfaces of the reinforcing material are aligned with each other in the longitudinal direction of the fastening surface. A plurality of fastening holes are provided so as to be inclined with respect to the fastening tool, and the first inner surface of the frame-shaped member is aligned with the fastening holes along the longitudinal direction of the first inner surface. It may be configured to be provided with a plurality of holes which are arranged in communication and into which the fastener is inserted. Then, the reinforcing member is arranged in a state of being fastened and fixed to the frame-shaped member and the reinforcing member is inclined with respect to the longitudinal direction of the frame-shaped member. Therefore, the reinforcing material is held in a state where one end and the other end are in contact with each of the facing inner surfaces of the frame-shaped member, and the reinforcing material is displaced or rotated with respect to the frame-shaped member. Is prevented.

The fitting according to the present invention includes an opening frame fixed to a building frame and supporting a face material or a shoji, and a shoji stile supported by the opening frame, and at least one of the opening frame and the sash. May be composed of the frame-shaped member. Then, even if the opening frame or the frame is made of resin, its deformation can be suppressed.

In the fitting according to the present invention, at least the opening frame is composed of the frame-shaped member, and the connecting member connecting the shoji and the opening frame is the reinforcing material inserted into the opening frame. It may be configured to be fastened and fixed with a fastener. Then, the connecting member that receives the weight of the shoji is connected to the reinforcing material whose misalignment is prevented by the resistance applying portion. Therefore, it is possible to prevent the reinforcing material from being displaced due to the weight of the shoji and causing the shoji to tilt.

According to the present invention, it is possible to improve the manufacturing efficiency and secure the reinforcing effect of the resin frame-shaped member by the reinforcing material.

Next, a specific configuration of the reinforcing material 32 will be described. FIG. 4 is a diagram showing a configuration example of the reinforcing member 32 inserted into the hollow portion 27 of the vertical frame 14c. FIG. 5A is a cross-sectional view showing a state in which the reinforcing material 32 shown in FIG. 4 is inserted into the hollow portion 27, and FIG. 5B shows a state in which the reinforcing material 32 is fastened and fixed to the vertical frame 14c from the state shown in FIG. 5A. It is a cross-sectional view which shows.

As shown in FIGS. 4 to 5B, the reinforcing member 32 is an extruded profile made of a metal such as aluminum. The reinforcing member 32 is a rod-shaped member having a substantially U-shaped cross section and extending along the longitudinal direction of the hollow portion 27 of the vertical frame 14c. The reinforcing member 32 has a pair of side wall portions 58, 59 facing each other and a central wall portion 60 connecting one ends of the pair of side wall portions 58, 59. The reinforcing material 32 may be formed by bending a metal plate such as steel or stainless steel into a substantially U shape.

The central wall portion 60 is a portion that is arranged in contact with the first inner surface 27a, which is one inner surface of the hollow portion 27, and is fastened by screws 62. That is, the outer surface of the central wall portion 60 is the fastening surface 60a of the reinforcing member 32 to the vertical frame 14c. The first inner surface 27a is the inner surface of the wall portion forming the outdoor side finding surface 28 of the hollow portion 27. A fastening hole 60b into which a screw 62 is screwed is formed in the central wall portion 60 (fastening surface 60a). The first inner surface 27a is provided with a hole 27e which is arranged in communication with the fastening hole 60b and into which the screw 62 is inserted. A plurality (for example, three) of the fastening holes 60b and the hole portions 27e are provided side by side along the longitudinal direction of the reinforcing member 32 and the vertical frame 14c, respectively.

The fastening surface 60a is provided with a plurality of protrusions 60c and recesses 60d. Each protrusion 60c protrudes from the fastening surface 60a in a substantially triangular cross section, and is a ridge extending in the longitudinal direction of the reinforcing member 32. The protrusions 60c are arranged in the width direction (X direction) of the reinforcing member 32, and a total of four protrusions 60c are provided on both sides of the fastening hole 60b (recessed portion 60d). The number of protrusions 60c installed may be changed. The height of the protrusion 60c is, for example, about 1 to 1/20 of the plate thickness of the central wall portion 60, for example, assuming that the plate thickness of the central wall portion 60 is 1.5 to 3 mm, the height of the protrusion 60c is It is set to about 0.1 to 1 mm. Each protrusion 60c imparts in-plane resistance between the first inner surface 27a and the fastening surface 60a, and functions as a resistance-imparting portion 64 that regulates the displacement of the reinforcing member 32 in the hollow portion 27.

The recess 60d is a portion in which the fastening surface 60a is lowered by the same height as the protrusion 60c, and is a shallow groove portion extending in the longitudinal direction of the reinforcing member 32. The fastening hole 60b is formed in the recess 60d. That is, the recess 60d is provided around the fastening hole 60b which is the fastening portion by the screw 62.

One side wall portion 58 is a portion that is arranged in contact with the second inner surface 27b of the hollow portion 27. The second inner surface 27b is an inner surface orthogonal to the first inner surface 27a, and is an inner surface of a wall portion forming an outer prospective surface of the vertical frame 14c. That is, the outer surface of the side wall portion 58 is a positioning surface (positioning portion) 58a that regulates the position of the reinforcing member 32 in the hollow portion 27 in the direction (X direction) along the fastening surface 60a. The reinforcing member 32 is positioned by arranging the fastening surface 60a and the positioning surface 58a in contact with the first inner surface 27a and the second inner surface 27b, respectively, and the fastening hole 60b is reliably arranged corresponding to the hole portion 27e.

The other side wall portion 59 is a portion that is arranged so as to face the third inner surface 27c of the hollow portion 27 via the gap C1 (see FIG. 5B). The third inner surface 27c is an inner surface that is orthogonal to the first inner surface 27a and faces the second inner surface 27b, and is an inner surface of a wall portion that forms an inner prospective surface (shoji arrangement portion 18) of the vertical frame 14c. That is, the outer surface of the side wall portion 59 is a gap facing surface 59a that forms a gap C1 with the third inner surface 27c. The reinforcing material 32 is easily inserted into the hollow portion 27 by providing the gap C1 between the gap facing surface 59a and the third inner surface 27c.

A gap C2 is also formed between the tip surfaces 58b and 59b of the side wall portions 58 and 59 and the fourth inner surface 27d of the hollow portion 27 (see FIG. 5B). The fourth inner surface 27d is an inner surface facing the first inner surface 27a. As a result, the work of inserting the reinforcing material 32 into the hollow portion 27 is even easier.

Next, the mounting structure of the reinforcing member 32 will be described.

First, as shown in FIG. 5A, the reinforcing material 32 is inserted into the hollow portion 27 from the edge of the vertical frame 14c. At this time, the reinforcing material 32 is inserted into the hollow portion 27 in a posture in which the respective surfaces 60a, 58a, 59a face the respective inner surfaces 27a, 27b, 27c, respectively. Then, when the fastening surface 60a (projection 60c) is brought into contact with the first inner surface 27a and at the same time the positioning surface 58a is brought into contact with the second inner surface 27b, the fastening hole 60b coincides with the hole portion 27e.

Next, as shown in FIG. 5B, the screw 62 is screwed into the fastening hole 60b through the hole 27e, and the vertical frame 14c and the reinforcing member 32 are fastened and fixed. Then, the metal protrusion 60c provided on the fastening surface 60a is in a state of being bitten into the resin first inner surface 27a by the fastening force of the screw 62. As a result, the reinforcing member 32 is firmly fixed to the vertical frame 14c in the hollow portion 27. At this time, the reinforcing member 32 is prevented from being displaced in the gap C1 direction due to the biting action of the protrusion 60c on the first inner surface 27a. That is, the protrusion 60c constituting the resistance applying portion 64 imparts resistance in the in-plane direction (here, the X direction) between the contact surfaces of the first inner surface 27a and the fastening surface 60a, thereby preventing the reinforcing member 32 from being displaced. To.

When the screw 62 drills the inner wall surface of the fastening hole 60b, burrs are generated, and the burrs are discharged to the recess 60d. Therefore, it is possible to prevent the burr from being caught in the protrusion 60c and being sandwiched between the fastening surface 60a and the first inner surface 27a, making it impossible to obtain an appropriate fastening strength and fastening posture. Further, by providing the recess 60d, burrs remaining on the peripheral edge of the fastening hole 60b and the hole 27e may be caught in the protrusion 60c or may be sandwiched between the fastening surface 60a and the first inner surface 27a. It can be avoided.

In the fitting 10, one mounting plate 30a of the hinge 30 is arranged on the outdoor side finding surface 28 of the vertical frame 14c, and the mounting plate 30a is fastened together with the reinforcing material 32 using screws 62 (see FIG. 5B). .. As a result, the hinge 30 (mounting plate 30a) that receives the weight of the shoji 16 can be received by the metal reinforcing material 32 instead of the resin vertical frame 14c. However, due to the weight of the shoji 16, an external force is applied to the mounting plate 30a and the reinforcing member 32 fastened to the mounting plate 30a toward the right side in the X direction in FIG. 5A. However, since this external force is received by the biting force of the protrusion 60c with respect to the first inner surface 27a, the displacement of the reinforcing member 32 in the X direction and the inclination of the shoji 16 due to this displacement are suppressed.

Since the reinforcing material 52 inserted into the hollow portion 47 of the vertical frame 36c of the shoji 16 has substantially the same structure as the reinforcing material 32 described above, the same reference numerals are given in FIG. 3 for detailed description. Is omitted. That is, the reinforcing member 52 includes a central wall portion 60 having a fastening surface 60a, a fastening hole 60b, a protrusion 60c and a recess 60d, a side wall portion 58 having a positioning surface 58a, and a side wall portion 59 having a gap facing surface 59a. Similarly, since the hollow portion 47 into which the reinforcing member 52 is inserted and fixed has substantially the same structure as the hollow portion 27 described above, the same reference numerals are given in FIG. 3 and detailed description thereof will be omitted. That is, the hollow portion 47 has a first inner surface 27a, a second inner surface 27b, a third inner surface 27c, and a fourth inner surface 27d. The screw 62 for fastening and fixing the reinforcing member 52 to the vertical stile 36c is fastened together with the other mounting plate 30b of the hinge 30 arranged on the outer prospective surface 50 of the vertical stile 36c. As a result, the other mounting plate 30b of the hinge 30 is also fastened and fixed to the metal reinforcing member 52 instead of the resin vertical frame 36c.

Therefore, with respect to the reinforcing material 32A, the same or similar elements as the reinforcing material 32 described above are designated by the same reference numerals, detailed description thereof will be omitted, and the same applies to the following reinforcing materials 32B to 32E.

The reinforcing member 32A has a central wall portion 60 and a side wall portion 59, and is formed in a substantially L-shaped cross section. The end face of the reinforcing member 32A on the side opposite to the side wall portion 59 of the central wall portion 60 serves as a positioning surface (positioning portion) 58a. The positioning surface 58a of the reinforcing member 32A may be formed by, for example, a curved surface.

Therefore, when the reinforcing material 32A is attached to the vertical frame 14c, the reinforcing material 32 is inserted into the hollow portion 27 from the edge of the vertical frame 14c as shown in FIG. Then, the fastening surface 60a (projection 60c) is brought into contact with the first inner surface 27a, and at the same time, the positioning surface 58a is brought into contact with the second inner surface 27b so that the fastening hole 60b is aligned with the hole portion 27e. Next, the screw 62 is screwed into the fastening hole 60b through the hole 27e to fasten and fix the vertical frame 14c and the reinforcing member 32A, and at the same time, the mounting plate 30a of the hinge 30 is fastened together. As a result, the reinforcing member 32A is attached and fixed to the vertical frame 14c in a strong fastening state in which the protrusion 60c of the fastening surface 60a bites into the first inner surface 27a.

A reinforcing material having the same structure as the reinforcing material 32A may be used instead of the reinforcing material 52 for the hollow portions 47 of the vertical frames 36c and 36d of the shoji 16.

An uneven shape portion 66 is provided on the fastening surface 60a of the reinforcing member 32C. The uneven shape portion 66 is a serration shape in which uneven shapes extending in the longitudinal direction of the reinforcing member 32C are arranged in the width direction (X direction) of the fastening surface 60a. The first inner surface 27a of the hollow portion 27 that comes into contact with the fastening surface 60a is provided with a concave-convex shape portion 67 that meshes with the concave-convex shape portion 66. The uneven shape portion 67 is a serration shape in which uneven shapes extending in the longitudinal direction of the vertical frame 14c are arranged in the width direction (X direction) of the first inner surface 27a. These uneven shape portions 66 and 67 form the resistance imparting portion 64A.

Therefore, when the reinforcing material 32C is attached to the vertical frame 14c, the reinforcing material 32C is inserted into the hollow portion 27 from the edge of the vertical frame 14c as shown in FIG. Then, at the same time that the fastening surface 60a is brought into contact with the first inner surface 27a, the positioning surface 58a is brought into contact with the second inner surface 27b so that the fastening hole 60b is aligned with the hole portion 27e. Next, the screw 62 is screwed into the fastening hole 60b through the hole 27e to fasten and fix the vertical frame 14c and the reinforcing member 32C, and at the same time, the mounting plate 30a of the hinge 30 is fastened together. As a result, the reinforcing member 32C is attached and fixed to the vertical frame 14c in a strong fastening state in which the concave-convex shape portions 66 and 67 of the fastening surface 60a and the first inner surface 27a are engaged with each other.

The concave-convex shape portion 67 may be provided in the hollow portion 47 of the vertical frames 36c and 36d of the shoji 16, and a reinforcing material having the same structure as the reinforcing material 32C may be used instead of the reinforcing material 52.

FIG. 11 is a cross-sectional view showing a state in which the reinforcing material 32D according to the fourth modification is inserted into the hollow portion 27.

As shown in FIG. 11, the reinforcing material 32D has a configuration in which a recess 60d is provided on the fastening surface 60a of the reinforcing material 32C shown in FIG. FIG. 11 illustrates a configuration in which a pair of left and right recesses 60d are provided as in the reinforcing material 32B shown in FIG. 9, but only one recess 60d may be provided as in the reinforcing material 32 shown in FIG. 5B.

Therefore, in the reinforcing material 32D, burrs and the like generated by the screw 62 drilling the inner wall surface of the fastening hole 60b can be discharged to the recess 60d. Therefore, it is possible to prevent burrs from being sandwiched between the fastening surface 60a and the first inner surface 27a and making it impossible to obtain normal fastening strength and fastening posture.

By the way, in the above-mentioned reinforcing material 32, if the height and width of the protrusion 60c are too small, sufficient resistance is not provided, and it is difficult to prevent the reinforcing material 32 from being displaced. On the other hand, if the height or width of the protrusion 60c is too large, the first inner surface 27a made of resin may be cracked or lifted. Therefore, at the beginning of the design of the reinforcing material 32, it is preferable to form the reinforcing material 32 with the minimum height and width of the protrusions 60c, and adjust the size of the protrusions 60c according to the actual objects of the vertical frame 14c and the vertical frame 36c. .. This adjustment may be easily performed, for example, by appropriately scraping the protrusion 60c portion of the mold for forming the reinforcing material 32 which is an aluminum profile and providing the protrusion H1 on the protrusion 60c (see FIG. 12). is there.

It is preferable that the width dimensions (Z-direction dimensions) of the side wall portions 58 and 59 of the reinforcing member 32 are initially formed to be the minimum size, and the gap C2 in FIG. 5B is secured to be large. That is, if the gap C2 is too large, the rattling of the reinforcing member 32 in the hollow portion 27 becomes large, and there is a possibility that the fastening hole 60b and the hole portion 27e are misaligned when the screw 62 is fastened, resulting in a decrease in workability. is there. On the other hand, if the gap C2 is too small, the tip surfaces 58b and 59b may interfere with the fourth inner surface 27d and the like when the reinforcing member 32 is inserted into the hollow portion 27, and workability may be reduced. Therefore, at the beginning of the design of the reinforcing material 32, the side wall portions 58 and 59 are formed with the minimum width dimension, and the size of the side wall portions 58 and 59 is adjusted to match the actual size of the vertical frame 14c and the vertical frame 36c. Should be adjusted. For this adjustment, for example, the tip surfaces 58b and 59b of the mold for forming the reinforcing material 32, which is an aluminum profile, may be appropriately shaved to provide a build-up portion H2 on the tip surfaces 58b and 59b (see FIG. 13). , Easy to implement.

The shape correction of the reinforcing material 32 by the built-up portions H1 and H2 can be similarly performed for the other reinforcing materials 32A to 32D.

That is, the fastening holes 60b are provided so that their alignment directions L are inclined with respect to the longitudinal direction (vertical direction V) of the fastening surface 60a. On the other hand, as described above, the arrangement direction of the holes 27e of the vertical frame 14c coincides with the vertical direction V which is the longitudinal direction of the vertical frame 14c. That is, the holes 27e are lined up along the longitudinal direction of the first inner surface 27a.

Therefore, when the reinforcing material 32E is attached to the vertical frame 14c, the reinforcing material 32E is inserted into the hollow portion 27, and each fastening hole 60b is aligned with each hole portion 27e and fastened with screws 62. Then, as shown in FIG. 15, the reinforcing member 32E is fixed in the hollow portion 27 in a posture tilted by the inclination of the alignment direction L with respect to the longitudinal direction (vertical direction V) of the vertical frame 14c. Therefore, the reinforcing member 32E is in a state in which the positioning surface 58a at the upper end thereof is in contact with the second inner surface 27b and the gap facing surface 59a at the lower end thereof is in contact with the third inner surface 27c. As a result, when the shoji 16 is attached to the hinge 30 connected and fixed to the reinforcing material 32E as shown in FIG. 16, the reinforcing material 32E may be displaced clockwise in FIG. 16 due to the weight of the shoji 16. Be prevented. Moreover, the reinforcing material 32E is further reliably prevented from being displaced by providing the resistance applying portion 64 or the resistance applying portion 64A. The reinforcing member 32E may not include the resistance applying portion 64 or the resistance applying portion 64A, and may simply have a configuration in which the alignment direction L of the fastening holes 60b is inclined with respect to the longitudinal direction of the fastening surface 60a.
