  However, each of the split vertices 50 and 60 described in Patent Documents 1 and 2 is provided with an engagement piece such that the one-side split stand and the other-side split stand have overlapping margins in the indoor and outdoor directions (see FIG. 7 is an engagement piece 54, and in the division stand 60 shown in FIG. 8 is an engagement piece 63, 64), and the tight material provided on this engagement piece is in close contact with the inside of the division stand It has a structure to do. Specifically, a structure having a holding portion for holding the tight members 55 and 65 in the fitting concave portion, and a protruding portion that protrudes in a fin shape from the holding portion and whose front end portion is in close contact with one side. In this case, water tightness is provided by closely contacting the inner side of one side stand by the bending reaction force of the protruding portion. In such a structure, since the tight surface of the tight material has only the tip of the fin-like protrusion, water tightness is insufficient, and the tightness of the protrusion is easily lowered due to deterioration of the tight material, etc. However, there was a case where sufficient was not secured.

  Further, in the vertical frame member 70 for windows shown in FIG. 9, the tightness 77 is secured by compressing the projecting portion 75 of the tight member 77 between the one-side split stand 71 and the other-side split stand 72. However, as shown in FIG. 6C, a protrusion 75 is interposed between both the lip pieces of the opening groove formed by the pair of left and right lip pieces and the other side split stand 72. Therefore, the repulsive force of the tight material 77 is increased, and the stress applied to the other side split stand 72 is increased. As a result, the joint of the abutting portion 70a is easily opened, and there is a problem that rainwater or the like easily enters or the appearance is damaged.

  Therefore, the main problem of the present invention is to prevent the intrusion of rainwater or the like from the outdoor side by disposing a pair of left and right split vertical frame members at the inside of the abutting portion at the corner of the outdoor side. Another object of the present invention is to provide a tight material with improved watertightness and a vertical frame material for windows having the same.

In order to solve the above-mentioned problem, the present invention according to claim 1 is a tight material disposed inside a butted portion where a pair of left and right split vertical frame members are abutted at least at an outdoor corner. And

The tightness of the tight material is secured by the outdoor protrusion of the seal portion being in close contact with the inside of the butted portion of the window vertical frame material. At this time, since the outdoor projecting portion is projected only in the outdoor direction, the projecting portion is projected in two directions, the outdoor side direction and the indoor side direction, as in the conventional tight material 77 shown in FIG. Compared to the case, the repulsive force applied to the other side split stand is reduced, and the opening of the butted portion can be prevented. For this reason, watertightness is ensured more stably and the appearance is improved.

  Further, the tight material has a groove formed along the longitudinal direction of the member on the outer surface portion of the outdoor projecting portion, so that the outdoor projecting portion becomes a vertical window for a window during a compressive load from the other split side. It becomes easy to deform inside the butt portion of the frame material, and the water tightness is secured to a higher degree. At the same time, the repulsive force is reduced, so that the butt portion can be prevented from opening.

  It should be noted that the outdoor-side protruding portion continuously protrudes “indirectly” from the tip end portion of the leg portion is provided with an indirect portion (for example, a connecting portion 16 described later) that connects the two from the tip end portion of the pair of leg portions. And an outdoor side protruding portion protruding only in the outdoor direction from the indirect portion.

  As a second aspect of the present invention, the outdoor projecting portion is formed directly and continuously bent from the distal end portion of each leg portion in the outdoor side direction, and is joined at the end portion, and is substantially inside. The tight material according to claim 1, wherein an L-shaped hollow portion is formed.

  The invention according to claim 2 specifically defines the case where the outdoor projecting portion continuously projects “directly” from the tip end portion of the leg portion, and directly from the tip end portion of each leg portion. It is formed into a so-called hollow shape which is continuously bent in the outdoor direction and is formed by joining at the end thereof, and a substantially L-shaped hollow portion is formed inside. Thus, by assembling the hollow type hollow frame material for the window by assembling a hollow hollow shape inside the seal portion, the entire seal portion is deformed integrally and fits inside the butted portion, At the same time as water tightness is secured, the repulsive force is also reduced, so that the opening of the butt portion can be prevented.

  According to a third aspect of the present invention, there is provided the tight material according to any one of the first and second aspects, wherein a groove is formed along the longitudinal direction of the member on the base side surface of the outdoor projecting portion. The

  In the invention described in claim 3 above, the groove on the base side of the outdoor projecting portion is also formed along the longitudinal direction of the member to further improve the fit to the inside of the butted portion. is there.

A plurality of connecting screws 4 for connecting the one-side split stand 2 and the other-side split stand 3 are provided at predetermined intervals along the longitudinal direction of the member.

  As shown in FIG. 4, the one-side split stand 2 has a pair of left and right lip pieces 6a and 6b at a position inside the outdoor side surface 1a and in the vicinity of the other side prospective surface 1d. A tight material mounting portion 7 having a groove-shaped cross section with the open groove 5 facing the other side split stand 3 is provided. The tight material attaching portion 7 is provided with a predetermined tight material 10.

  On the other hand, as shown in FIG. 3, an upright piece 8 for alignment is formed inside the abutting portion 1 f inside the indoor side surface 1 b of the one-side split stand 2.

  As shown in FIG. 4, the tight material 10 is provided with a base portion 11 fitted and attached to the opening groove 5, and a pair of facing leg portions 13 and 13 erected from the base portion 11. The leg portions 13 and 13 are provided with an outdoor projecting portion 14 that bends directly and continuously in the outdoor direction from the front end portions of the legs 13 and 13 and that protrudes only in the outdoor direction when the front end portions are coupled to each other. And a sealing portion 12. Thereby, the inside of the seal portion 12 is formed in a so-called hollow shape, which is a substantially L-shaped hollow portion from the leg portion 13 to the outdoor protrusion 14.

  The outdoor projecting portion 14 contacts the first tight surface 14 a that contacts the outdoor lip piece 6 a and the inner surface side of the other side split stand 3 among the pair of left and right lip pieces 6 a and 6 b. And a second tight surface 14b. The first tight surface 14a and the lip piece 6a are in close contact with each other, so that intrusion of rain water or the like into the opening groove 5 is prevented, and the second tight surface 14b and the inner surface of the other split partition 3 are in close contact with each other. This prevents rainwater and the like from entering the interior of the vertical 1. Thereby, intrusion of rainwater or the like from the butted portion 1e into the vertical 1 can be prevented.

  On the outer surface portion (second tight surface 14b) of the outdoor projecting portion 14, a plurality of groove portions 15, 15... Are formed along the longitudinal direction of the member. The groove portion 15 is preferably formed by providing a cut inside the outline of the outdoor projecting portion 14, and in particular, the cut shape is preferably V-shaped as illustrated.

  Furthermore, the groove part 20 can be similarly formed along the member longitudinal direction on the surface (the first tight surface 14a) on the base 11 side of the outdoor projecting part 14. Thereby, the fitting property to the inner side of the butting portion 1e is improved.

  The tight material 10 is formed by molding a resin material such as vinyl chloride or olefin, and is formed in an elongated shape. The base portion 11 and the seal portion 12 may have the same hardness, but may have different hardnesses. When the hardness is different, it is preferable that the base portion 11 has a higher hardness than the seal portion 12. For example, the base 11 can have a hardness of 90 °, and the seal portion 12 can have a hardness of 50 °.

  The leg portions 13 and 13 are portions existing inside the opening groove 5 in a state where the tight material 10 is attached to the tight material attaching portion 7. Therefore, in the tight material 10 of the form shown in FIG. 4, a portion that continues directly from the tip portion of the leg portion 13, that is, a portion that exists outside the opening groove 5 constitutes the outdoor protrusion 14. The pair of legs 13 and 13 can be formed with the same thickness, but can also be formed with different thicknesses. In the case of forming with different thicknesses, it is preferable that the thickness of the outdoor leg portion 13 is made thinner than the thickness of the indoor leg portion 13. Thereby, at the time of compression of the outdoor side protrusion part 14 explained in full detail in a back | latter stage, a leg part becomes easy to fall down to an outdoor side, and can improve the adhesiveness of the tight material on the outdoor side.

  In assembling the vertical member 1, first, the base 11 of the tight member 10 is fitted into the opening groove 5 of the one-side split vertical member 2, so that the outdoor protruding portion 14 of the tight member 10 is moved to the outdoor lip piece 6 a. It is set as the state arrange | positioned on the outer surface side. Next, the other side split stand 3 is combined so as to close the other side prospective surface which is the opening of the one side split stand 2 to which the tight material 10 is attached, and the one side split stand is connected with the connecting screw 4. 2 and the other side dividing stand 3 are connected. By tightening the connecting screw 4, the outdoor projecting portion 14 is compressed between the lip piece 6 a and the other side split stand 3 so as to be in close contact with the lip piece 6 a and the other side split stand 3. (See FIG. 6A).

  The deformation of the tight material 10 will be described in detail with reference to FIG. 6A. Since the tight material 10 is formed in a hollow shape, when the compression from the other side split stand 3 is applied, the seal portion 12 is placed in the room. Deforms to spread outward. However, with respect to the outdoor side direction, the deformation of the outdoor side protruding portion 14 is restricted by the abutment with the inner surface of the one-side split stand 2 and the deformation is restricted with respect to the indoor side direction. Of the legs 13, 13, the indoor-side leg 13 abuts against the tip of the indoor-side lip piece 6b, and deformation is restricted. When the deformation is restricted in this way and further compressed by the other side split stand 3, it usually becomes a repulsive force toward the other side split stand 3 and causes the abutting portion 1 e to open. In the tight material 10 according to the present invention, since the groove portion 15 is formed in the outer surface portion of the outdoor-side protruding portion 14, the outer surface portion of the outdoor-side protruding portion 14 is recessed inward using the groove portion 15 as a flexible shaft. Deformed. Specifically, the intermediate portion in the indoor / outdoor direction of the outer surface portion of the outdoor projecting portion 14 is recessed, and the second tight surface 14b is divided into the other side split stand 3 at two locations on the outdoor side and indoor side of the concave portion. It comes in contact with the inner surface.

  Next, a tight material 10 'according to another embodiment will be described with reference to FIG. The tight material 10 ′ is configured such that the outdoor projecting portion 14 ′ is provided indirectly and continuously from the distal ends of the pair of leg portions 13 and 13 erected from the base portion 11.
