Description

  The present invention relates to a cover material attached to a resin frame installed in a housing opening of a building and a resin sash to which the cover material is attached.

  Conventionally, an aluminum sash (aluminum sash) has been widely used for windows of houses. Aluminum sash is advantageous in terms of durability and manufacturing cost but has problems in heat insulation performance and condensation. Therefore, in recent years, resin-made sash (resin sash) has been widely used. The resin sash is a sash frame (frame) installed at the opening of a frame of a building, or a barrier material of shoji provided on the inside of this frame formed of resin such as vinyl chloride resin (PVC).

  With regard to such a resin sash, Patent Document 1 discloses a reform structure of a resin sash in which the fire resistance performance is improved by covering the indoor side portion of the frame with a metal cover material.

  By the way, in the entrance corner part 102 of the building 100 as shown in FIG. 14, since the escape of the wind W of outside air is bad, the heat is difficult to escape, and there is also an influence of the reflection of the solar radiation S between the windows 104, 104 installed there. The ambient temperature of the window 104 tends to rise.

  Therefore, it has been found that when a resin sash is used for the window 104 of such an inward corner portion 102, the temperature of the resin sash itself may rise excessively depending on weather conditions etc., and thermal deformation may occur. For example, when the resin sash is formed of a vinyl chloride resin, the elastic modulus of the material sharply decreases in the vicinity of about 80 ° C., which is the softening temperature, and it is in a state of being easily deformed. The temperature rise of the resin sash is also related to the product color. For example, in the case of a dark color system such as black or brown, the solar absorptivity is higher than that of a light color system such as white, and even under the same weather conditions, the temperature rises easily. Further, as the inside corner portion 102, as shown in FIG. 14, in addition to the shape obtained by cutting out the outer wall corner portion of the building 100 by about 90 degrees, the shape obtained by denting the outer wall of the building 100 at an acute angle (see FIG. 15) There are various structures, such as both inward corner parts (refer to FIG. 16) which are formed by indenting the outer wall of the rectangular shape.

  Usually, as shown in FIG. 17, the lower frame 106a of the resin sash 106 is loaded with the weight of the shoji 110 and the weight of the resin sash 106 itself. Therefore, when the temperature rises above the softening temperature of the resin material constituting the resin sash 106, the lower frame 106a and the draining portion 108 projecting outward from the lower frame 106a are softened and waved (see FIG. 17A). There have been reported cases where deformation such as crushing or crushing (see FIG. 17B) is likely to occur. If the frame is deformed, the appearance quality of the resin sash 106 will be impaired.

  The present invention has been made in consideration of the above-mentioned problems of the prior art, and a cover material capable of suppressing the deformation of the frame and maintaining the appearance quality even when the outdoor temperature rises, and the cover The object is to provide a resin sash to which a material is attached.

  The cover material according to the present invention is a metal cover material attached to a frame formed of a resin upper frame, a lower frame, and left and right vertical frames, and the upper frame, the lower frame, and the left and right vertical frames And at least one of the frames is a mounting target frame, and is mounted along the longitudinal direction of the outdoor side portion so as to cover a prospective surface of the outdoor side portion projecting from the mounting target frame to the outdoor side. I assume.

  According to such a configuration, even if the temperature of the frame rises excessively, the prospective surface of the outdoor side portion of the frame is covered with the metal cover material, so the shape of the frame is a cover It is corrected by the material, the deformation due to heat can be suppressed, and the appearance quality of the resin sash can be maintained for a long time. And since the cover material is metal, heat dissipation is good and it is also possible to suppress the temperature rise of the resin sash itself.

  It is preferable that the cover material which concerns on this invention is a length dimension which is not contact | abutted with the frame provided in the both sides of the said attachment object flame | frame. Then, the temperature rises above the softening temperature of the resin constituting the frame, and even if the frame is contracted or the cover material is expanded, the frames and the cover material provided on both sides of the mounting object frame The clearance secured between them prevents interference between the frame and the cover material, and can prevent the cover material and the frame from being deformed or damaged. Also, when the temperature decreases, the amount of shrinkage of the resin becomes larger than the amount of shrinkage of the metal cover material, but even when the resin shrinks at such a low temperature, the frame and the cover material interfere with each other. Can be prevented.

  The cover material according to the present invention comprises a first cover portion covering a prospective surface of a draining portion extended from the outdoor side vertical surface of the mounting object frame toward the outdoor side, and a first cover portion covering the outdoor side end surface of the draining portion. It is good to have 2 cover parts. Then, it is possible to suppress deformation of the draining portion that is considered to have the highest possibility of thermal deformation at the outdoor side portion of the frame due to the influence of solar radiation and the like.

  The cover material according to the present invention is provided continuously from the first cover portion, and has a third cover portion covering the outdoor side vertical surface, and between the first cover portion and the third cover portion. The angle may be set larger than the angle between the prospective surface of the water drain and the outdoor vertical surface. Then, the cover material can be fixed in a state in which the third cover portion is in contact with the outdoor vertical surface of the frame, and the third cover portion is positioned and fixed in a state having an elastic repulsive force toward the indoor side. Therefore, the stability of the cover material after mounting is improved.

  The cover material according to the present invention is attached to the attachment object frame by the turn nut disposed inside the attachment object frame and the screw screwed from the outer surface side of the cover material to the turn nut. It may have a cosmetic cover which covers the screw exposed on the outer surface of the cover material. In the structure using the turn nut, it is not necessary to arrange the nut in advance inside the draining portion, and it is not necessary to form an internal thread on the wall surface of the draining portion, and the cover material can be easily attached. Therefore, the cover material can be easily retrofitted to the existing resin sash, and the versatility of the cover material is improved. Furthermore, the cosmetic cover can further improve the appearance quality of the resin sash.

  The resin sash according to the present invention is characterized in that the cover material having the above-mentioned configuration is attached. As a result, even when the temperature of the resin sash is excessively increased, it is possible to suppress the deformation of the frame and to prevent the deterioration of the appearance quality.

  Further, a resin sash according to the present invention is a resin sash to which the cover material having the above-described configuration is attached, and a cap covering the longitudinal direction end of the cover material and the decorative cover is provided in the draining portion of the attachment object frame. It is characterized in that it is attached to the prospect surface. This can prevent the edges of the longitudinal end portions of the cover material and the decorative cover from being exposed to the outside.

  According to the present invention, even when the temperature of the frame rises excessively, the prospective surface of the outdoor side portion of the frame is covered with the metal cover material, so the shape of the frame is covered by the cover material It can be corrected, heat deformation can be suppressed, and the appearance quality of the resin sash can be maintained for a long time.

  Hereinafter, preferred embodiments of the cover material according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a resin sash 10 according to an embodiment of the present invention as viewed from the outdoor side. FIG. 2 is an enlarged perspective view of the lower portion of the resin sash 10 shown in FIG. 3 is a vertical cross-sectional view of the lower portion of the resin sash 10 shown in FIG. 2, and FIG. 3 (A) is a view showing a state before attachment of the cover member 12, and FIG. 3 (B) is a cover member It is a figure which shows the state after 12 of attachment.

  In the present embodiment, a resin sash 10 which is installed inside a housing opening 14 of a building such as a house and is used as a FIX window having a facing 16 which does not open and close is exemplified. The resin sash 10 can be used in various applications such as various windows such as vertical sliding windows or sliding windows, and various doors such as terrace doors or self-opening doors.

  As shown in FIG. 1, the resin sash 10 includes a frame 18 fixed to the inside of the housing opening 14. The frame 18 is configured by framing an upper frame 18a, a lower frame 18b, and left and right vertical frames 18c and 18c around the four circumferences. The upper frame 18a, the lower frame 18b, and the vertical frame 18c are members obtained by extruding a resin such as a vinyl chloride resin (PVC). The upper frame 18a, the lower frame 18b, and the vertical frame 18c are formed by the same frame member cut at a predetermined length, and their cross-sectional shapes are the same. The frame 18 is configured such that the end portions of the upper frame 18a, the lower frame 18b, and the vertical frame 18c which are cut at 45 degrees are appropriately butted and joined.

  The upper frame 18a, the lower frame 18b, and the vertical frame 18c each include an indoor side portion 20 disposed on the indoor side with the surface member 16 separating the indoor and the outdoor, and an outdoor side portion 22 disposed on the outdoor side. A cover member 12 described later is attached to the outdoor side portion 22 of the lower frame 18b. The face material 16 is, for example, a two-layered double-layered glass in which two glass plates 16a, 16a are integrally formed via a spacer 16b (see FIG. 3). The cover material 12 is attached to the outdoor side part 22 of the lower frame 18b (refer FIG.1 and FIG.2).

  As shown in FIG. 3, the lower frame 18 b has a portion 24 in which the facing 16 is disposed on the prospective surface, and has a projecting portion 26 at a portion closer to the room than the portion 24. A draining portion 32 is provided at a portion to be the outdoor side. Between the portion 24 and the draining portion 32, an outdoor side vertical surface 30 which is an outdoor side looking surface is provided so that the draining portion 32 is one step lower than the portion 24. As described above, the upper frame 18a and the vertical frame 18c have the same cross-sectional shape as the lower frame 18b. After the face material 16 is attached to the portion 24, the face material 16 made of glass is provided between the projecting portion 26 and the attachment edge 28 by attaching the attachment edge 28 to the outside. It is held. In addition, in order to clarify the structure of the cover material 12, in FIG. 2, illustration of the protrusion part 26 and the ledge 28 which comprise the part 24 is abbreviate | omitted, It is made the same also about FIG.

  By the way, when the resin sash 10 configured in this way is installed at a location where temperature rise is likely to occur, such as the inside corner 102 of the building 100 as shown in FIG. 14 to FIG. If the softening temperature (for example, the glass transition temperature of the resin) is exceeded, the problem of deformation of the water draining portion 32 or the like as shown in FIG. 17 is concerned. Such a temperature rise is a problem which is also a concern in the resin sash 10 installed on a thick wall whose outer wall is thick and which easily accumulates heat. In particular, when a thin acrylic laminate for coloring is formed on the surface of polyvinyl chloride resin, for example, as the resin constituting the resin sash 10 used for such an inward corner portion 102 or thick wall, the product color is In the case of dark color, the solar absorptivity is high and tends to be higher. As an example, in the case where the solar absorptivity of the resin sash 10 is about 16% when the product color is light white and is about 70 to 75% for dark brown or black. It is done.

  Therefore, in the resin sash 10 according to the present embodiment, the cover member 12 is attached to the outdoor side portion 22 of the lower frame 18b where the deformation at the time of temperature rise is most concerned, thereby suppressing the deformation of the frame 18; Its appearance quality and function are prevented from deteriorating. Below, among each frame which constitutes frame 18, although the composition which attached cover material 12 to lower frame 18b is illustrated and explained, cover material 12 is in outdoor side part 22 of upper frame 18a or vertical frame 18c. You may attach it. This is because the upper frame 18a and the vertical frame 18c may be deformed depending on the situation of the installation location of the resin sash 10. The cover material 12 may be attached in advance to the resin sash 10 that is newly manufactured and sold, or may be attached to the existing resin sash 10 as a retrofit.

  As shown in FIG. 2, the cover member 12 is attached to the outdoor side portion 22 of the lower frame 18 b so as to cover substantially the entire length in the longitudinal direction. As shown in FIGS. 2 and 3, the cover member 12 bends a metal belt-like flat plate into a substantially Z shape in the direction of its short side to form a first cover 12 a, a second cover 12 b, and a third A cover 12c is formed. The cover member 12 is formed of, for example, a metal plate material such as aluminum or stainless steel.

  The first cover portion 12 a is a portion slightly inclined toward the outdoor side so as to cover the upper surface (expected surface) 32 a of the draining portion 32. When the cover member 12 is attached to the lower frame 18b, the first cover portion 12a is a surface along the substantially horizontal direction. When the cover member 12 is attached to the upper frame 18a, the first cover portion 12a is a surface along the substantially horizontal direction, but when attached to the vertical frame 18c, the surface is a surface along the substantially vertical direction. On the lower surface of the first cover portion 12a, a leg portion 34 serving as a spacer that forms a gap with the upper surface 32a is provided. The legs 34 may be omitted, and the first cover 12 a may be in close contact with the upper surface 32 a of the draining portion 32.

  The second cover portion 12 b is a portion substantially orthogonal to the first cover portion 12 a so as to cover the outer side end surface (tip end surface) 32 b of the draining portion 32. In the second cover portion 12b, a through hole 38 for inserting a screw 36 for fixing the cover member 12 to the lower frame 18b is formed (see FIG. 3A). The through hole 38 is formed at a position in communication with the nut attachment hole 40 formed in the outdoor side end surface 32 b of the draining portion 32. The nut mounting hole 40 is a hole used when inserting and fixing the turn nut 42 from the outside to the inside of the draining portion 32. The second cover portion 12b is further formed with a rectangular hole 46 for exposing the drainage port 44 provided on the outdoor side end surface 32b of the drainage portion 32 to the outer surface (see FIG. 2). The drainage port 44 is an opening for draining rainwater or the like which has entered the inside of the draining portion 32 to the outside. As shown by a two-dot chain line in FIG. 3B, a lower cover portion 47 obtained by bending the lower end side of the second cover portion 12b to the indoor side is provided, and the outer side end surface 32b of the draining portion 32 is included. Good.

  The third cover portion 12c is provided continuously from the first cover portion 12a, and is a portion substantially orthogonal to the first cover portion 12a so as to cover the outdoor vertical surface 30 of the lower frame 18b. The rising amount of the third cover portion 12c from the first cover portion 12a can be set to an extent that it can cover the outdoor vertical surface 30 and does not reach the siding edge 28. This makes it possible to attach and remove the leading edge 28 without removing the cover member 12 and to correspond to the windows of the vertical sliding window and the like and the windows of the FIX window so as not to disturb the opening of the window. That is, the cover member 12 is a cover that covers substantially the entire outside portion 22 of the lower frame 18 b except the edging 28. As shown in FIG. 3A, in the state before the attachment of the cover member 12, the angle θ1 between the first cover portion 12a and the third cover portion 12c is the upper surface 32a of the drainage portion 32 and the outdoor vertical surface. It is set larger than the angle θ2 between 30 and 30.

  FIG. 4 is a cross-sectional view of the cover 12 attached to the lower frame 18b. In FIG. 4, in order to ensure the viewability of the drawing, hatching is illustrated with the vertical frame 18 c actually formed of hollow parts regarded as a solid part.

  As shown in FIG. 4, with respect to the longitudinal direction length of the cover member 12, clearances C1 each having a predetermined interval are formed between the vertical frames 18c and 18c provided on both sides of the lower frame 18b which is an attachment target frame. The length dimension, that is, the length dimension in which the cover material 12 does not abut on the vertical frames 18c on both sides thereof is set. Specifically, with respect to the distance L1 between the inner surfaces of the left and right vertical frames 18c, 18c, the first cover portion 12a and the third cover portion 12c disposed on the inner side pull the clearance C1 of both sides from the distance L1. The distance L2 (L2 = L1-2 × C1) is obtained. The second cover portion 12b disposed outside the left and right vertical frames 18c, 18c is larger than the distance L1 and has a distance L3 overlapping the vertical frames 18c in a plan view. In the case of the present embodiment, the clearance C1 is, for example, about 5 mm.

  An R-shaped chamfer 48 is applied to the upper end corner portions of both ends of the second cover portion 12 b and the upper end corner portions of both ends of the third cover portion 12 c which become the edge of the cover member 12.

  When such a cover member 12 is attached to the outdoor side portion 22 of the lower frame 18b, the turn nut 42 is fixed in advance to the inside of the draining portion 32, and as shown in FIG. The cover member 12 is disposed on the outdoor side portion 22 while aligning the nut mounting hole 40 with the nut mounting hole 40.

  Subsequently, as shown in FIG. 2 and FIG. 3B, the screw 36 is inserted through the through hole 38 and screwed into the turn nut 42 to fix the cover material 12 to the outdoor side portion 22. At this time, in the cover member 12, the angle θ1 between the first cover portion 12a and the third cover portion 12c is set larger than the angle θ2 between the upper surface 32a and the outdoor vertical surface 30 as described above. ing. Therefore, when the screw 36 is tightened, the upper portion of the third cover portion 12c abuts on the outdoor vertical surface 30, and is elastically pushed down to the outdoor side, so that the third cover portion 12c is elastically repelled to the indoor side. Positioning is fixed with force. Thus, no gap is formed between the upper end of the third cover portion 12c and the outdoor vertical surface 30, and rattling of the cover member 12 is also prevented. In addition, you may provide the protrusion 37 as shown with a dashed-two dotted line in FIG. 3 (A). The projection 37 is provided on the inner surface on the lower end side of the second cover portion 12 b and at a position close to the screw 36. When the projection 37 is provided, the cover member 12 is inclined to the indoor side, so the cover member 12 can be placed on the outdoor side portion 22 of the lower frame 18b without setting the elastic repulsive force by the third cover portion 12c as described above. It can be attached stably without rattling. In the case where the third cover 78c is fixed with the screws 36 as in a cover member 78 shown in FIG. 11 described later, a protrusion similar to the protrusion 37 is an inner surface on the upper end side of the third cover 78c. When the cover member 78 is provided at a position close to the screw 36, the cover member 78 is inclined to the outside, and the rattling is prevented.

  As described above, the resin sash 10 according to the present embodiment includes at least one of the upper frame 18a, the lower frame 18b, and the left and right vertical frames 18c and 18c that constitute the frame 18 (the lower frame in the present embodiment 18b) as a mounting object frame, along the longitudinal direction of the outdoor side portion 22 so as to cover the upper surface 32a of the draining portion 32 which is a prospective surface of the outdoor side portion 22 projecting from the lower frame 18b to the outdoor side. It has a metal cover 12 attached.

  Therefore, even if the temperature of the resin sash 10 is excessively increased and temporarily exceeds the softening temperature (about 80 ° C.) of the constituent material of the frame 18 (polyvinyl chloride resin in the present embodiment). Since the metallic cover member 12 is provided on the outdoor side portion 22 of the lower frame 18b, the shape of the lower frame 18b is corrected by the cover member 12 and deformation due to heat as shown in FIG. 17 can be suppressed. For this reason, the appearance quality of the resin sash 10 can be maintained for a long time. Further, even if the lower frame 18b is deformed, the deformed portion of the lower frame 18b is concealed by the cover member 12, so that the appearance quality of the resin sash 10 is not impaired. Moreover, since the cover material 12 is formed of a metal having higher thermal conductivity (heat dissipation property) than the resin constituting the frame 18, the heat accumulated in the resin sash 10 can be smoothly dissipated into the atmosphere. There is also an advantage that the temperature rise itself can be suppressed.

  In addition, the cover material 12 does not necessarily need to have all the parts of the 1st cover part 12a, the 2nd cover part 12b, and the 3rd cover part 12c, and should just have any one or multiple. For example, in the outdoor side portion 22 of the lower frame 18b, as is apparent from the example shown in FIG. 17, the upper surface 32a of the draining portion 32 is considered to be the portion where the possibility of thermal deformation is the highest. For this reason, the cover material 12 may be configured only by the first cover portion 12a. In addition, since the second cover portion 12 b covers the outdoor end surface 32 b of the draining portion 32, the appearance quality of the resin sash 10 can be further improved. On the other hand, when the third cover portion 12c is provided as described above, the third cover portion 12c abuts on the outdoor vertical surface 30 of the lower frame 18b to function like a leaf spring, so that the cover member 12 is attached. There is an advantage that the stability is increased and the occurrence of rattling can be suppressed.

  The frame 18 constituting the resin sash 10 is made of, for example, polyvinyl chloride resin. Usually, when extruding the frame 18 with such a resin, the resin hardens while the stress in the tensile direction remains in the material at the time of its shaping, and this tensile stress also remains in the frame 18 which is a product. Therefore, when the temperature of such a resin material rises above the softening temperature, the residual stress is released and the frame 18 shrinks rapidly. So, in this embodiment, the cover material 12 is set to the length dimension which does not contact | abut with the vertical frames 18c and 18c provided in the both sides of the lower frame 18b used as an attachment object frame (refer FIG. 4). As a result, even if the lower frame 18b to which the cover member 12 is attached and the vertical frames 18c on both sides of the cover 12 are contracted due to the influence of heat, this contraction is absorbed by the clearance C1, so that the cover member from the frame 18 It is prevented that 12 receives a pressing force, and a deformation | transformation and damage of the cover material 12 or the frame 18 can be avoided. That is, the clearance C1 serves as a buffer for absorbing the difference in thermal contraction rate between the resin and the metal. Furthermore, by providing the clearance C1, interference with the frame 18 can be suppressed even when the metal cover material 12 is stretched in the longitudinal direction by heat. Furthermore, when the temperature of the resin sash 10 decreases, the amount of contraction of the resin (frame 10) becomes larger than the amount of contraction of a metal (cover material 12) such as aluminum. Therefore, even when the frame 10 is greatly contracted at such a low temperature, interference between the frame 10 and the cover material 12 can be prevented by the clearance C1.

  In the resin sash 10, the cover material 12 is attached using a turn nut 42. As a result, it is not necessary to arrange a nut in advance inside the draining portion 32, and it is not necessary to form an internal thread on the wall surface of the draining portion 32, and the attachment of the cover material 12 is facilitated. Therefore, the cover material 12 can be easily retrofitted to the existing resin sash 10, and the versatility of the cover material 12 is improved.

  Next, each modification of the cover material 12 is demonstrated. In addition to the effects of the deformation suppression of the frame 18 by the cover material 12 described above and the maintenance of the appearance quality, various useful effects can be obtained in the following modifications.

  FIG. 5 is an enlarged perspective view of the lower portion of the resin sash 10 to which the cover member 50 according to the first modification is attached, and FIG. 6 is a longitudinal sectional view of the lower portion of the resin sash 10 shown in FIG. In FIGS. 5 and 6, the same reference numerals as those shown in FIGS. 1 to 4 indicate the same or similar configurations, and therefore, detailed description will be omitted as they have the same or similar functions and effects. The same applies to the following figures.

  In the cover member 12 shown in FIGS. 2 and 3, a part (head) of the mounting screw 36 is exposed on the appearance. Therefore, the cover member 50 is configured to have a screw hidden cover (makeup cover 52) for hiding the screw 36 on the appearance.

  As shown in FIGS. 5 and 6, the cover member 50 includes a cover main body 54 and a cosmetic cover 52. The cover main body 54 and the decorative cover 52 are both formed of a plate made of metal such as aluminum. In addition, in FIG. 6, the multilayer glass of three layers which integrally formed three glass plates 16a, 16a, and 16a via the two spacers 16b is illustrated as the surface material 16. As shown in FIG.

  The cover main body 54 has a first cover 12a, a second cover 12b, and a third cover 12c. Upper and lower end portions of the second cover portion 12b are provided with a pair of upper and lower engagement pieces 56, which protrude toward the outdoor side. Protrusions 56 a facing each other are provided on the inner surface of the tip end side of each engagement piece 56.

  The cosmetic cover 52 has the same longitudinal length as the second cover portion 12 b of the cover main body 54. A pair of upper and lower engagement claws 52a, 52a is provided on the outer surface of the interior of the cosmetic cover 52 on the indoor side. The cosmetic cover 52 can be fixed to the cover main body 54 by the engagement claws 52a engaging with the projections 56a of the engagement pieces 56 (see FIG. 6). As a result, it is possible to prevent the screw 36 from being hidden inside the cosmetic cover 52 and exposed on the appearance, and the appearance quality of the resin sash 10 can be further improved.

  As shown in FIG. 5, with respect to the longitudinal length of the cover member 50, clearances C1 and C2 each having a predetermined interval are formed between vertical frames 18c and 18c provided on both sides of the lower frame 18b which is an attachment target frame. The length dimension of the cover member 50, that is, the length dimension which does not abut the vertical frame 18c on both sides of the cover member 50 is also set. Specifically, the third cover portion 12c is set to a length dimension in which the same clearance C1 as the case of the cover member 12 shown in FIG. 4 is formed. The first cover portion 12a and the second cover portion 12b are set to a length dimension in which a clearance C2 larger than C1 is formed. The first cover portion 12a and the second cover portion 12b may have a length dimension in which the clearance C1 is formed similarly to the third cover portion 12c, but in the present embodiment, the first cover portion is formed by the cap 58 described later. In order to cover the end portions of the second cover 12a and the second cover 12b, the length dimension is set such that a larger clearance C2 is formed.

  That is, as shown in FIGS. 5 and 6, in the cover member 50, since the decorative cover 52 is attached to the outdoor side of the second cover portion 12b, the chamber of the draining portion 32 is compared with the cover member 12 shown in FIG. The amount of protrusion of the cover member 50 from the outer end face 32 b is large. Therefore, in the cover member 50, in order to protect the edge that largely protrudes to the outdoor side, it is preferable to provide a cap 58 so as to cover both longitudinal direction end portions (see FIG. 7).

  7 is an enlarged perspective view of an essential part in a state where the cap 58 is attached to the cover member 50 shown in FIG. 5, and FIG. 7 (A) is a view of the cap 58 as viewed from above. ) Is the figure which looked at the cap 58 from the downward direction. FIG. 8 is a perspective view of the cap 58 as viewed from below.

  As described above, the length of the cover member 50 in the longitudinal direction of the first cover 12a and the second cover 12b is set shorter than that of the third cover 12c (see FIG. 5). Therefore, the cap 58 is attached at a position covering the both end portions of the first cover portion 12a and the second cover portion 12b and at an inner side of the left and right vertical frames 18c and 18c (see FIG. 7A). ).

  As shown in FIG. 7A, FIG. 7B and FIG. 8, the cap 58 is formed of an upper plate 58a overlapping the upper surface of the first cover portion 12a of the cover member 50, and an outer end of the upper plate 58a. A side plate 58b is formed to be bent downward and overlaps with the outer surface of the second cover portion 12b of the cover member 50. The cap 58 is made of, for example, a resin.

  On the lower surface of the upper plate 58a, a pair of mounting claws 60, 60 are provided in a protruding manner. The respective attachment claws 60 are engageable with the indoor and outdoor long holes 62 (see FIG. 5) formed on the upper surface 32a of the draining portion 32 of the lower frame 18b exposed to the side of the first cover 12a. . That is, the cap 58 is fixed on the upper surface 32 a of the draining portion 32 by engaging the mounting claw portion 60 with the long hole 62.

  The side plate 58b is formed with an inclined surface 64 which is tapered toward the adjacent vertical frame 18c. The inclined surface 64 is a portion covering the side of the second cover 12 b of the cover member 50. A notch 66 is formed on the base end side of the inclined surface 64, and an opening 68 is formed between the notch 66 and the side plate 58b (see FIG. 7B). As is clear from FIG. 5, the rain water etc. drained from the drainage port 44 to the inside of the cosmetic cover 52 flows on the inside of the cosmetic cover 52 to both sides, and as shown in FIG. It is discharged from the opening 68 formed by the notch 66 to the outside.

  As shown in FIG. 7A, in the state where the cap 58 is attached to the draining portion 32 of the lower frame 18b, the first cover portion 12a is disposed inside the upper plate 58a, and the second cover is disposed inside the side plate 58b. Part 12 b is arranged. At this time, the cap 58 and the cover member 50 are not connected to each other, the upper plate 58a and the first cover portion 12a are relatively movable, and the side plate 58b and the second cover portion 12b are also relatively movable. For this reason, even if the frame 18 is contracted or the cover member 50 is expanded due to the temperature fluctuation of the resin sash 10, as shown by the broken-line arrow A in FIG. The cover member 50 relatively advances and retreats. Accordingly, the cap 58 and the frame 18 and the cover member 50 are in contact with each other to prevent an excessive load from being generated, thereby preventing their deformation and damage.

  FIG. 9 is a vertical cross-sectional view of the lower portion of the resin sash 10 to which the cover member 70 according to the second modification is attached.

  In the cover member 50 shown in FIG. 6, the cosmetic cover 52 is attached to the outer surface side of the second cover portion 12 b to hide the screw 36. On the other hand, in the cover member 70, the cover member 70 is attached to the outer surface side of the bracket 72 fixed to the draining portion 32 by the screw 36.

  As shown in FIG. 9, the cover member 70 has a first cover 70a, a second cover 70b, and a third cover 12c. The first cover portion 70 a has a width dimension that protrudes sufficiently beyond the drainage portion 32 toward the outdoor side. The second cover 70b is bent downward from the end of the first cover 70a and extends in a substantially vertical direction, and then has a shape bent toward the indoor side. Protrusions 73, 73 facing each other are provided on the upper and lower facing surfaces of the first cover portion 70 a and the second cover portion 70 b that project outward from the outdoor side end surface 32 b of the drainage portion 32.

  A plurality of brackets 72 are provided in the longitudinal direction of the draining portion 32 in accordance with the mounting places of the screws 36. That is, the longitudinal length of the bracket 72 is sufficiently short as compared with the longitudinal length of the cover 70. The bracket 72 is disposed in contact with the outer side end surface 32b of the draining portion 32 and is substantially vertically attached with a mounting portion 72a fixed by a screw 36, and a pair of upper and lower pairs projecting outward from the upper and lower end portions of the mounting portion 72a. And the engagement pieces 72b and 72b.

  Therefore, by engaging the projections 73 with the engagement pieces 72b of the brackets 72 fixed to the outdoor side end face 32b of the draining portion 32 with the screws 36, the cover member 70 is lowered with the screws 36 hidden. It can be attached to the frame 18b. In such a cover member 70, a bracket 72 having a short length is used instead of the decorative cover 52 having the same length as the longitudinal direction length of the second cover portion 12b like the cover member 50 shown in FIGS. Can be used to hide the screw 36.
