Description

[Detailed description of the invention] This invention strengthens each component, especially the parts to which loads are applied, and also strengthens the parts located on the outdoor side of the synthetic resin window frame material when attached to the attached member. The present invention relates to a window frame structure in a lower frame portion that allows a cover to be easily attached to the outside to prevent rainwater from entering.

Synthetic resin window frames tend to be widely used as window frames in cold regions due to their insulating properties, but because they are made of synthetic resin, they have the disadvantage of being inferior in strength compared to metal window frames. ing.

The window frame structure of the lower frame part of the present invention allows the outer window frame material to be stably attached to the attached member such as a wooden frame, and has two rails that support the sliding door, which bears the most load. In addition to reinforcing the lower part to ensure long-term use, the window frame material is made of synthetic resin with good moldability so that it can be easily covered with a cover to prevent rainwater from entering. The feature is that the cover does not easily fall off after installation.

The details of the present invention will be further explained based on illustrated embodiments.

In this invention, a window frame material made of synthetic resin such as vinyl chloride formed by extrusion molding is cut to an appropriate length to form the window frame at the lower side frame, and this window frame is attached to the side wall of the building. It is attached to the lower side of the opened window forming opening (not shown) to form the lower side frame portion of the window frame of the building.

The synthetic resin window frame material shown as 1 in the figure consists of two parallel strips on the top plate 2 of an internally hollow outer frame main body 6 consisting of an upper plate 2, a lower plate 3, an outer surface wall 4, and an indoor surface wall 5. The interior hollow sliding door rails are provided with one of the outdoor side rails 7 protruding above the outer surface wall 4 and the other indoor side rail 8 protruding from the approximate center of the upper plate 2,
Above the indoor side surface wall 5, the surface wall 5 is extended from the upper plate 2, and an internal hollow protrusion 13 is also provided, and a drainage groove 12 is provided between the protrusion 13 and the indoor side rail 8. A rail supporting wall 11 is erected between the upper plate 2 and the lower plate 3 of the outer frame main body 6 below the rail 8,
The lower plate 3 has two or more mounting legs 10 made of two opposing protrusions 9, 9, and at least one mounting leg 10 is located below the outdoor rail 7, and the other mounting leg 10 is located below the outdoor side rail 7.
The two mounting legs 10 are located below the indoor rail 8, and in the illustrated embodiment, two other mounting legs 10 are provided below.

Here, one of the opposing inner surfaces of the opposing protrusions 9, 9 constituting the mounting leg portion 10 has a bent tip 9a.
One bulge part has a semicircular cross section, and the other part has a bulge part 9b having a semicircular cross section, and the tip surfaces of each part are flush with each other.

Furthermore, among the mounting leg parts 10, the mounting leg part 10 located below the outdoor side rail 7 has a semicircular cross section 9.
A protrusion 9 having a bulge portion b is arranged on the outside,
A cover, which will be described later, is attached to this protrusion 9 having a bulge having a semicircular cross section 9b.

Therefore, the outdoor side rail 7 is attached to the upper surface of the lower side of a member to be attached, such as a wooden frame, which is attached to the window forming opening made in the side wall of the building, where such a synthetic resin window frame material 1 is shown as 14 in the figure. Mounting leg part 10 arranged at the lower part
Of these, only the protrusion 9 having a bulge having a semicircular cross section 9b is left as a free end when attached.

In the figure, reference numeral 15 indicates a frame, and reference numeral 16 indicates a protrusion 9 having a bulge having a semicircular cross-section 9b located at the outer circumferential end of the window frame material 1 attached to the attached member 14. This is a cover that is applied externally from the outdoor side to prevent the infiltration of rainwater, etc., and the lower part of the cover 16 located below the outdoor side rail 7 is fixed with an exterior mortar finish 17, and is further caulked 18. .

In the window frame structure of the lower frame portion of the present invention as described above, the mounting leg 1 is constituted by opposing protrusions 9, 9 with the tip surfaces flush with each other.
Synthetic resin window outer frame material 1 formed by installing two or more 0
, it is not only possible to stably attach it to the member to be attached 14 , but also to attach one protrusion 9 of the outer surface wall 4 and one of the mounting legs 10 to the lower part of the indoor rail 8 . By locating the rail support wall 11 and another mounting leg 10 in the lower part, this part where the weight of glass etc. above the outdoor rail 7 and indoor rail 8 is added is reinforced. Therefore, the strength of the window outer frame material 1 as a whole can be increased and it can be used for a long period of time.

Furthermore, since it can withstand a large weight, it can also be applied to window frames with large areas.

Furthermore, the mounting leg 10 located below the outdoor rail 7 has a protrusion 9 having a bulge having a semicircular cross section 9b.
Since the cover 16 is positioned with a free end left, when the cover 16 is attached to the protrusion 9, the cover 1
The wall thickness of the part to be attached such as the protrusion provided in 6 is the mounting leg 1.
Even if the width is larger than the gap width of 0, the protrusion 9 has a free end shape, and due to the shape of the bulge, one side of the attached part of the cover 16 when inserted is the tip of the bulge 9b, which has a semicircular cross section. Since only the surfaces are in contact, the insertion operation is facilitated, and strict dimensional accuracy between the two is not required.

Further, after the cover 16 is attached in this way, the bulge provided on the protrusion 9 prevents the cover 16 from falling off easily.

Furthermore, by making the outdoor side rail 7, indoor side rail 8, and protrusion 13 of the synthetic resin window frame material 1 hollow, sufficient strength can be achieved even when the entire window frame material 1 has a substantially uniform wall thickness. As a result, compared to reinforcing the material by making it thicker, it is easier to form the material during extrusion molding, and a material with no distortion can be obtained.
