  In order to prevent water from entering between the frame and the reinforcing member, it is conceivable to provide a watertight material between them. That is, an L-shaped water-tight material having a first portion sandwiched and compressed between the first extension portion and the fin portion, and a second portion sandwiched and compressed between the second extension portion and the frame body. Intrusion of water can be prevented by providing.

  However, if the watertight material is sandwiched between the frame body and the reinforcing member and excessively compressed, the repulsive force of the compressed watertight material on the reinforcing member increases, and the interval between the reinforcing member and the frame body increases, and the water There is a problem that makes it easy to penetrate.

  This invention is made | formed in view of this subject, The place made into the objective is to suppress appropriately permeation of water between a frame and a reinforcement member.

In order to achieve such an object, the joinery of the present invention includes a frame body having a frame body and a fin portion extending from the frame body,
A first extending portion that extends along the fin portion and is fastened to the housing by a fastening member in a state where the fin portion is sandwiched between the housing and an end portion of the first extending portion to the frame body. An L-shaped reinforcing member having a second extending portion extending toward the outdoor side so as to follow,
A joinery having
An L-shape having a first portion compressed between the first extension portion and the fin portion, and a second portion compressed between the second extension portion and the frame body. With watertight material,
A joinery characterized in that a reducing portion for reducing a repulsive force of the compressed second portion against the second extending portion is provided in a portion other than the outdoor front end portion of the second portion. is there.

  According to such a joinery, the repulsive force is reduced overall by providing the mitigating portion. Therefore, it is possible to prevent the space between the frame body and the reinforcing member (the space between the second extending portion and the frame body) from widening, and appropriately prevent water from entering between the frame body and the reinforcing member. Is possible.

Such joinery,
The mitigation part is preferably a hole.

  According to such a joinery, the effect of reducing the repulsive force is further increased. Therefore, the gap between the frame and the reinforcing member (the gap between the second extension portion and the frame main body) is further suppressed, and water can more appropriately enter between the frame and the reinforcing member. It becomes possible to suppress.

Such joinery,
The second extension part preferably has a protrusion protruding toward the frame body.

  According to such a joinery, the degree of compression of the second portion of the watertight material can be made constant (uniform) regardless of the operator. Therefore, an error that the operator attaches the reinforcing member and the watertight material to the frame body in a state where the degree of compression is excessively large does not occur. Therefore, it is possible to appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material is too large and water enters.

Such joinery,
The mitigation part is a hole;
It is desirable that the tip of the protruding portion is in contact with the frame body in a state where the protruding portion is located in the hole.

  According to such a joinery, since the tip directly contacts the frame body, the operator can easily obtain a feeling that the tip contacts the frame body. Therefore, the degree of compression of the watertight material (second part) can be made constant (uniform) regardless of the operator. Therefore, it is possible to more appropriately prevent the inconvenience that the repelling force of the watertight material (second portion) is too large and water enters.

Such joinery,
The second extension part preferably includes a hole.

  According to such a joinery, even if water should invade from the entrance, it will come out of the hole before reaching the housing. Therefore, even if water enters between the lower frame and the reinforcing member, it is possible to prevent water from reaching the housing.

=== About the sliding window 10 according to the present embodiment ===
A sliding window 10 as an example of a fitting according to the present embodiment will be described with reference to FIGS. 1 and 2.

  In the following description, when the sliding window 10 attached to a building or the like is viewed from the indoor side, the vertical direction is the vertical direction, the horizontal direction is the horizontal direction, and the indoor / outdoor direction. The depth direction is shown as the prospective direction. Even if it is each part of the sliding window 10 and each member constituting the sliding window 10 is in a single state, it is mounted in a building or the like in the up-down direction, the left-right direction, and the prospective direction. The direction will be specified and described.

  The sliding window 10 according to the present embodiment is a synthetic resin window, and includes a frame 20 and a shoji 40. Of course, the sliding window 10 may be made of an aluminum alloy.

  The frame 20 includes an upper frame 30, a lower frame 32, and left and right vertical frames 35. The upper frame 30, the lower frame 32, and the left and right vertical frames 35 are all synthetic resin extruded members. The frame 20 has an opening as a whole, with the four frames being framed in a rectangular shape. The upper frame 30 and the lower frame 32 are long members extending in the left-right direction, and the vertical frame 35 is a long member extending in the vertical direction.

  The shoji 40 is a member accommodated in the opening formed by the frame 20, and includes an outer shoji 40a and an inner shoji 40b.

  The shoji 40 is provided to be slidable with respect to the frame 20. The shoji 40 includes a housing 41 and a multilayer glass 42 attached to an opening formed by the housing 41.

<<< About the structure of the lower frame 32 and its surroundings >>>
Next, the configuration of the lower frame 32 and its periphery according to the present embodiment will be described with reference to FIGS. 3 to 8B. 8A is a diagram showing a cut surface of the lower frame 32, the reinforcing member 60, and the watertight material 70 taken along the one-dot chain line of FIG.

  The lower frame 32 (frame body 20) includes a lower frame main body 50 as an example of a frame main body and a lower frame fin portion 52 (so-called nail fin) as an example of a fin portion.

  The lower frame main body 50 is a portion that is located below the shoji 40 and supports the shoji 40 (the outer shoji 40a and the inner shoji 40b).

  As shown in FIG. 3, the lower frame fin portion 52 is an extending portion extending from the lower frame main body 50, and a fixing portion when the lower frame 32 is fixed to the housing 80 with a screw 82 as an example of a fastening member. As a function. The lower frame fin portion 52 extends downward from the lower frame main body 50, in other words, in an orthogonal direction substantially orthogonal to the lower frame main body 50. Moreover, the lower frame fin part 52 is provided from the one end part in the left-right direction of the lower frame 32 (lower frame main body 50) to the other end part.

  Further, a reinforcing member 60 is attached to the lower frame main body 50 and the lower frame fin portion 52 via a watertight material 70 described later. The reinforcing member 60 is for reinforcing the frame body 20. In particular, since the reinforcing member 60 is provided with respect to the lower frame 32, the weight of the shoji 40 (gravity applied to the shoji 40) causes the outdoor portion of the lower frame 32 (lower frame body 50) (in FIG. 1). , The portion indicated by the symbol A) plays a role of inhibiting the lower frame 32 (lower frame body 50) from being supported. In the present embodiment, the reinforcing member 60 is a metal (stainless steel) member, and a plurality (three in the present embodiment) are provided at equal intervals in the left-right direction.

  As shown in FIGS. 4 and 7A, the reinforcing member 60 has an L-shape (not necessarily requiring a strict L-shape), and the lower frame fin portion in which the L-shapes are substantially orthogonal to each other. 52 and the lower frame main body 50 are attached from the lower frame fin portion 52 to the lower frame main body 50 along the L-shaped portions. That is, the reinforcing member 60 includes a first extending portion 62 that extends downward along the lower frame fin portion 52, and a chamber extending from the one end portion 62 a of the first extending portion 62 along the lower frame main body 50. A second extending portion 64 extending outward is provided. The first extension part 62 is located outside the lower frame fin part 52, and the second extension part 64 is located below the lower frame body 50.

  In addition, it has been described that the lower frame fin portion 52 has a function as a fixing portion when the lower frame 32 is fixed to the housing 80 with the screw 82. However, the lower frame fin portion 52 includes the reinforcing member 60 and the housing 80. It is screwed to the housing 80 in a state of being sandwiched between the two. That is, as shown in FIG. 3, the first extending portion 62 of the reinforcing member 60 is fastened to the housing 80 by the screw 82 in a state where the lower frame fin portion 52 is sandwiched between the housing 80.

  Further, a watertight material 70 is provided between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60. That is, the watertight member 70 is formed on the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60, as is apparent by comparing FIGS. 7A and 7B (or FIGS. 8A and 8B). It is sandwiched and compressed. In the present embodiment, the watertight material 70 is a synthetic resin (sponge) member, and a plurality (three in the present embodiment) are provided at equal intervals in the left-right direction, like the reinforcing member 60. It has been.

  The watertight material 70 is for suppressing water from entering between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60.

  Specifically, as shown in FIG. 3, an outer wall 84 is provided below the lower frame 32 (lower frame main body 50), and a seal is provided between the lower frame main body 50 and the upper end of the outer wall 84. Sealed with a material 86. Even at the position where the reinforcing member 60 (second extending portion 64) is provided, an outer wall 84 is provided below the reinforcing member 60 (second extending portion 64). Since the space between the outer wall 84 and the reinforcing member 60 is sealed with the sealing material 86, when the watertight material 70 is not provided, the space between the lower frame 32 and the reinforcing member 60 is water from the outside. Is the only path through which water enters (if water enters from the outside, the water enters the indoor side of the outer wall 84). In such a case, as shown in FIG. 3, the water that has entered from the inlet G1 between the lower frame main body 50 and the second extending portion 64 and moved to the outlet G2 falls from the outlet G2 and wets the casing 80. (Also, there is a possibility that the water may enter the housing 80 through the screw 82 before moving to the outlet G2). Therefore, a watertight material 70 is provided so as not to cause such inconvenience.

  The watertight material 70 has substantially the same shape as the reinforcing member 60. That is, as shown in FIGS. 5 and 7A, the watertight material 70 has an L shape (a strict L shape is not essential), and the L shapes are substantially perpendicular to each other. Between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60 so as to follow both the L-shaped portion of the frame fin portion 52 and the lower frame main body 50 and the L-shape of the reinforcing member 60. Is provided. That is, the watertight material 70 is compressed between the first extension portion 62 and the lower frame fin portion 52 and compressed between the first portion 72 and the second extension portion 64 and the lower frame body 50. And two portions 74.

  The first portion 72 extends downward along the lower frame fin portion 52, as with the first extension portion 62, and the second portion 74, as with the second extension portion 64, It extends toward the outdoor side along the lower frame main body 50 from the one end 72a. As shown in FIGS. 6 and 7A, the extension tip of the first extension portion 62 and the extension tip of the first portion 72 are aligned in the extension direction, and the extension tip of the second extension portion 64 is the same. And the position in the extending direction of the extending tip of the second portion 74 also coincides.

  In addition, it has been described that the first extending portion 62 is fastened to the housing 80 with the screw 82 in a state where the lower frame fin portion 52 is sandwiched between the housing 80, but the first extending portion 62 is formed of the watertight material 70. Is also sandwiched. That is, the first extension portion 62 is fastened to the casing 80 by the screw 82 in a state where the first extension portion 62 and the casing 80 sandwich the first portion 72 and the lower frame fin portion 52.

  By the way, when the watertight material 70 is compressed by being sandwiched between the lower frame 32 (the lower frame main body 50 and the lower frame fin portion 52) and the reinforcing member 60, the repulsive force of the compressed watertight material 70 against the reinforcing member 60 (watertight material). Force that 70 presses the reinforcing member 60). When the compression becomes excessive, the repulsive force increases, and the interval between the reinforcing member 60 and the lower frame 32 is widened, which may cause a problem that water can easily enter. In particular, in the present embodiment, the first extension portion 62 and the casing 80 are fastened to the casing 80 by screws 82 in a state where the first portion 72 and the lower frame fin portion 52 are sandwiched. Therefore (that is, the fastening of the reinforcing member 60 is only the fastening of the first extending portion 62), the interval between the lower frame main body 50 and the second extending portion 64 is easily spread by the repulsive force of the watertight material 70.

  Therefore, as shown in FIG. 5 and FIG. 8A, the reduction for reducing the repulsive force of the compressed second portion 74 against the second extending portion 64 on the portion other than the outdoor tip 74 a of the second portion 74. (In this embodiment, a hole 74b for reducing the area) is provided. In other words, by providing the mitigating portion (hole 74b), the area of the repulsive force generation site can be reduced, so that the repulsive force is reduced as a whole. Therefore, an increase in the distance between the lower frame 32 and the reinforcing member 60 (the distance between the second extending portion 64 and the lower frame main body 50) is suppressed, and water enters between the lower frame 32 and the reinforcing member 60. This can be suppressed appropriately.

  On the other hand, since the hole 74b is provided in a portion other than the outdoor front end portion 74a of the second portion 74, a decrease in water stoppage capability due to the provision of the hole 74b does not occur. That is, since the watertight material 70 is left without providing the hole 74b at the inlet G1 in the water intrusion path, the ingress of water can be reliably suppressed.

  The hole 74b according to the present embodiment has a rectangular shape as shown in FIG. In the prospective direction, the hole 74b is provided in all of the second portion 74 (up to the indoor-side tip) except for the outdoor front end portion 74a, and in the left-right direction, the hole portions excluding both end portions 74c are provided. 74b is provided.

  As described above, in the present embodiment, the hole 74b is provided in the watertight material 70 in order to reduce the repulsive force of the watertight material 70 and appropriately suppress the entry of water. However, the magnitude of the repulsive force can vary depending on the attachment work of the worker who attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32. That is, since the degree of compression of the water-tight material 70 when attaching the reinforcing member 60 and the water-tight material 70 to the lower frame 32 is different depending on the worker (because it is different), the repulsive force is also different, and the worker is in a state where the degree of compression is excessively large. May have the inconvenience that the repulsive force is too great and water permeates (even though the repulsive force is reduced by the hole 74b).

  Therefore, as shown in FIGS. 4 and 8A, the second extending portion 64 of the reinforcing member 60 is provided with a protruding portion (in the present embodiment, a cut-and-raised portion 64a). By providing the cut-and-raised portion 64 a in the second extending portion 64, when the operator attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32, the tip 64 b of the cut-and-raised portion 64 a has the lower frame main body 50. (See FIG. 8A). Then, the operator can obtain a feeling that the tip 64b contacts the lower frame body 50. Therefore, as shown in FIG. 8A, the worker attaches the reinforcing member 60 to the screw 82 when the contact is made (when the feeling is obtained). If it fixes by this, the relative position with respect to the lower frame main body 50 of the 2nd extension part 64 will become fixed (uniform) irrespective of an operator. Therefore, the degree of compression of the second portion 74 (particularly, the outdoor front end portion 74a) sandwiched between the second extending portion 64 and the lower frame main body 50 is also constant (uniform) regardless of the operator.

  Thus, in the present embodiment, as shown in FIG. 8A, the second extending portion 64 includes the protruding portion (cut-raised portion 64a) protruding toward the lower frame body 50. The degree of compression of the two portions 74 (outdoor tip 74a) can be made constant (uniform) regardless of the operator (variation of the compression degree by the operator can be eliminated). Therefore, an error in which the operator attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32 in a state where the degree of compression is excessively large does not occur. Therefore, it is possible to appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material 70 (second portion 74) is too large and water enters.

  In the present embodiment, the cut and raised portion 64a has a rectangular shape, and as shown in FIG. 8A, the tip 64b of the cut and raised portion 64a is located with the cut and raised portion 64a positioned in the hole 74b. It is in contact with the lower frame body 50. That is, both ends in the left-right direction of the cut-and-raised portion 64a are located inside both ends in the left-right direction of the hole 74b, and both ends in the expected direction of the cut-and-raised portion 64a are inside of both ends in the expected direction of the hole 74b. Is located. Therefore, when the worker attaches the reinforcing member 60 and the watertight material 70 to the lower frame 32, the cut and raised portion 64a is inserted into the hole portion 74b.

  In the present embodiment, the degree of compression of the second portion 74 (specifically, the outdoor front end portion 74a) when the front end 64b contacts the lower frame main body 50 (hereinafter referred to as a contact compression rate). ) Is set to be equal to or higher than an appropriate compression degree (hereinafter referred to as an appropriate compression rate) in the specification of the watertight material 70. Here, the said appropriate compression rate is a minimum compression required in order to exhibit the water stop capability of the watertight material 70 appropriately. That is, if the appropriate compression rate is 60%, for example, the contact compression rate is set to be 60% or higher than 60%. In addition, if the watertight material 70 makes a compression rate high too much, the said repulsive force will raise. Therefore, in consideration of such matters, it is desirable to set the compression rate at the time of contact substantially equal to the appropriate compression rate.

  As described above, in the present embodiment, the degree of compression of the second portion 74 (outdoor tip 74a) is constant (uniform) regardless of the operator, so that the water-tight material 70 (second portion 74) It is possible to appropriately prevent the inconvenience that the repulsion force is too large and cause the invasion of water, and it is possible to reliably exhibit the desired water stopping ability regardless of the operator.

  In the present embodiment, in order to prevent the intrusion of water and to exhibit an appropriate water stopping capability, the second extending portion 64 of the reinforcing member 60 is provided with the cut and raised portions 64a. As shown in FIGS. 4 and 8A, a hole is formed in the two extending portions 64. The hole portion functions as a drain hole 66. That is, in the present embodiment, since the water drain hole 66 is provided, even if water has entered from the entrance G1, the water drain hole 66 is just before reaching the housing 80. It will come out (it will fall down. The state of falling is indicated by a white arrow in FIG. 8A). Therefore, even if water has entered between the lower frame 32 and the reinforcing member 60, it is possible to prevent water from reaching the housing 80.

  In the present embodiment, as shown in FIG. 4, three drain holes (for convenience, the first drain hole 66a, the second drain hole 66b, and the third drain hole are provided as the drain holes 66. 66c). Any drainage hole 66 is provided at a position corresponding to the hole 74 b of the watertight material 70.

  Since the tip 64b of the cut-and-raised part 64a is formed so as to be positioned on the outdoor side in the prospective direction with respect to the fulcrum 64c of the cut-and-raised part 64a, the first drain hole 66a extends from the second extending part 64. It is adjacent to the cut-and-raised portion 64a in the direction (expected direction) and is located outside the cut-and-raised portion 64a. The second drain hole 66b and the third drain hole 66c are adjacent to the cut and raised portion 64a in the left-right direction and are located outside the cut and raised portion 64a.

=== Other Embodiments ===
The above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified and improved without departing from the gist thereof, and it goes without saying that the present invention includes equivalents thereof.

  In the said embodiment, although the sliding window 10 was mentioned as an example and demonstrated as a fitting, it is not limited to this, What kind of thing may be used if it is a fitting with a frame.

  Moreover, in the said embodiment, although the lower frame 32 (lower frame main body 50 and lower frame fin part 52) was mentioned as an example and demonstrated as the frame 20 which provides the reinforcement member 60 and the watertight material 70, it is limited to this. It is not something. For example, it is good also as providing with respect to the upper frame 30 (the upper frame main body 30a and the upper frame fin part 30b) and the vertical frame 35 (the vertical frame main body 35a and the vertical frame fin part 35b). That is, the present invention can be applied not only to the reinforcing member 60 and the watertight material 70 provided for the lower frame 32 but also to the reinforcing member 60 and the watertight material 70 provided for the upper frame 30 and the vertical frame 35. is there.

  Moreover, in the said embodiment, although the hole 74b was provided as a reduction part for reducing repulsive force, it is not limited to this. For example, it is good also as providing the thin part whose thickness of the watertight material 70 is thinner than another location instead of the hole 74b.

  However, since the effect of reducing the repulsive force is greater when the reduction part is the hole part 74b than when it is a thin part, the above embodiment is preferable in this respect.

  Further, in the above embodiment, the mitigating portion is the hole 74b, and the tip 64b of the protruding portion (cut-raised portion 64a) is in the lower position while the protruding portion (cut-raised portion 64a) is positioned in the hole 74b. Although it is in contact with the frame main body 50, it is not limited to this. For example, when the mitigating part is the thin part, the tip 64b of the projecting part (cut-and-raised part 64a) may be in contact with the lower frame body 50 with the thin part interposed therebetween.

  However, in the above-described embodiment, the tip 64b directly contacts the lower frame main body 50, so that the operator can easily feel that the tip 64b contacts the lower frame main body 50. Therefore, the degree of compression of the second portion 74 (outdoor tip 74a) can be made constant (uniform) regardless of the operator. Therefore, it is possible to more appropriately prevent the occurrence of inconvenience that the repelling force of the watertight material 70 (second portion 74) is too large to cause water intrusion. In this respect, the above embodiment is preferable.

  Moreover, in the said embodiment, as shown to FIG. 8A, it formed so that the front-end | tip 64b of the cut-and-raised part 64a might be located in the outdoor side in a prospective direction rather than the fulcrum 64c of the cut-and-raised part 64a. Therefore, the second extending portion 64 includes a drain hole 66 (that is, the first drain hole 66a) at a position adjacent to the cut and raised portion 64a in the extending direction (expected direction) of the second extending portion 64. The cut-and-raised portion 64a is located on the indoor side of the first drain hole 66a.

  However, the present invention is not limited to this. For example, as shown in FIG. 9, the tip 64b of the cut-and-raised portion 64a is formed to be positioned on the indoor side in the prospective direction with respect to the fulcrum 64c of the cut-and-raised portion 64a. The cut-and-raised portion 64a may be located on the outdoor side of the first drain hole 66a.

  However, in the above embodiment, when the outer wall 84 and the sealing material 86 are not present during construction of the building or the like, or when the sealing material 86 is torn due to an unforeseen situation after construction, the splash should be on the lower side. Even if it flies upward from the top and enters through the first drain hole 66a (see the black arrow heading to the upper right in FIG. 8A), the tip 64b of the cut-and-raised portion 64a that is in contact with the lower frame body 50 is sprayed. Therefore, it is possible to avoid the movement of the splash toward the housing 80 (inside the room). In this respect, the above embodiment is preferable.

  Moreover, in the said embodiment, although the cut and raised part 64a was mentioned as an example as a protrusion part of the 2nd extension part 64, it was not limited to this. For example, instead of cutting the second extending portion 64, one surface of the second extending portion 64 may be recessed and the other surface expanded to form a convex portion as a protruding portion in the second extending portion 64. Good.

  However, since the drain hole 66 is automatically formed by cutting and raising the protruding portion 64a, there is a merit that it is not necessary to form the drain hole 66 separately. Is preferable.
