Description

[Detailed description of the invention] This invention relates to a synthetic resin window frame consisting of a fixed frame and a window frame body.

Regardless of the type of fittings housed in the window frame, the structure of the fixing part to the window opening forming frame is almost the same. On the other hand, the structure of the fittings storage section differs depending on the type of fittings accommodated in the window frame.
Focusing on this point, the window frame is divided into a fixed frame that is fixed to the window opening forming frame and a window frame body that houses the fittings, and a fitting connection means is provided between the fixed frame and the window frame body. By providing a fixing frame, a fixed frame is used that is common to all window frame bodies regardless of the type of fittings to be erected, and a window frame body that is suitable for the type of fittings to be erected is selected and used. Technical ideas have already been proposed that facilitate assembly of window frames and attachment to buildings.

However, in conventional window frames of this type, the connection between the window frame body and the fixed frame was not strong enough, and strong winds could cause the joint to vibrate and make noise, or rainwater could enter through the joint due to capillary action. There were some shortcomings.

Therefore, the object of this invention is to provide a synthetic resin window frame which eliminates the above-mentioned drawbacks with a simple structure.

Next, an embodiment of this invention will be explained based on the drawings. 1 is the upper frame on the window frame body, 2 is the lower frame, 3, 4
are the left and right vertical frames, both of which are made of synthetic resin profiles, and are connected in a square shape using block-shaped L-shaped corner joints (not shown) to form the window frame body. There is.

Each of the frames 1 to 4 has the same cross-sectional shape. The upper frame 1 is shown in detail in Fig. 3,
To explain, the upper frame has an indoor wall 5 and an outdoor wall 6.
, an outer circumferential side wall 7 and an inner circumferential side wall 8 are integrally formed, and a hollow protrusion 9 protruding toward the inside of the window is provided at the indoor end of the inner circumferential side wall 8, so that the cross-sectional shape of the entire frame is is almost hollow L-shaped. 10, 11, 12
is a reinforcing web.

Further, each frame has protruding walls 13, 14, 15, 1 extending toward the outer circumferential side of the outer circumferential side wall 7, as shown in FIG.
6, 17, 18, and the adjacent projecting wall 1
Between 3, 14, 14, 15 and projecting walls 16, 17,
A groove 1 opening outward between 17 and 18, respectively.
9, 20, 21, and 22 are formed. Reference numeral 23 denotes a screw receiving portion constructed between the protruding walls 15 and 16.

Each of the above-mentioned frames 1 to 4 has a block-shaped L-shaped corner joint (not shown) press-fitted into the end of the largest hollow part 24, and the screw receiving part 23
A screw (not shown) passing through the outer peripheral side wall 7 is screwed into the corner joint to form a rectangular connection to form the window frame body.

25 is the upper frame of the fixed frame, 26 is the lower frame of the fixed frame, 2
7 and 28 are fixed vertical frames. Each of these frames 25
28 are slightly different in overall shape, but each have similar members. That is, each frame 25 to 28 has nails 3 attached to the outdoor side of the window opening forming frame such as the lintel 29, the window sill 30, and the pillar 31.
a first mounting edge 34 fixed by a screw 33 or the like, a second mounting edge 35 fixed to the inner peripheral surface of the window opening forming frame by a screw 33 or the like, and a connecting board 36 connecting the two mounting edges. and a pair of protrusions 37, 38 protruding toward the center of the window at both indoor and outdoor ends of this board.
and an exterior facing edge 39 extending toward the outdoors from the first mounting edge 34. and,
The pair of protrusions 37 and 38 form a fitting groove 40 between them that opens on the inside of the window. This fitting groove 40 is for fitting the outer peripheral side portions of each frame of the window frame main body with a gap such that capillary action is blocked. In the illustrated preferred embodiment, the protrusions 37 and 38 are fitted between the outer peripheral protruding walls 13 and 14 and between 17 and 18, and the protruding walls 14 to 17 are fitted into the fitting groove 40. Thereby, capillary action blocking gaps are formed in the grooves 20, 21 between the adjacent protruding walls 14, 15, 16, 17.

Reference numeral 41 denotes a reinforcing protrusion that protrudes toward the window frame main body at the center of the connecting board 36, and when each frame of the window frame main body is fitted to each frame of the fixed frame, this reinforcing protrusion 41 is connected to the projecting wall 15. , 16 and the screw receiving part 23, thereby increasing the fitting strength of each corresponding frame. The screw penetration part is reinforced.

When the window frame main body is connected to the fixed frame as described above, a minute gap may be formed between the surface of the fixed frame and the surface of the window frame main body at the connection portion to the extent that drafts cannot enter. If the gap is continuous from the outdoor side to the indoor side, there is a risk that rainwater from the outdoor side will seep into the indoor side due to capillary action. However, since the window frame body is fitted into the fitting groove 40 with a capillary action blocking gap, rainwater is prevented from seeping into the room. Note that, as in the illustrated embodiment, recesses 37a and 38a are formed on the outdoor and indoor sides of the protrusions 37 and 38, respectively, and the protrusions 37 and 38 are connected to the pair of protrusions on the outdoor and indoor sides of the window frame body. When tightly fitted between the walls 13, 14, 17, 18, the protrusions 37, 38 and the projecting wall 1
Since a capillary action blocking gap is also formed between 3 and 18, the effect of preventing rainwater from seeping in is better exhibited.

Then, the window frame main body is fitted into the fitting groove 40 formed between the projections 37 and 38, and the connecting board 3
Since it is connected to the fixed frame by being fixed with the screw screwed in from 6, the connection can be easily and firmly made. In this case, according to the illustrated embodiment, the projecting walls 14, 17 are connected to the projections 37,
38, and the reinforcing protrusion 4
1 is also fitted between the projecting walls 15 and 16, and furthermore, the screw 42 passes through the reinforcing projection 41 and is inserted into the screw receiving part 23.
Because it is screwed into the window frame, the fixed frame and the window frame body are very firmly connected. Moreover, in the basic idea of this invention, the concave groove 40 between the protrusions 37 and 38
Since the window frame main body is fitted and fixed with screws 42, the structure is simple and the connection is secure. Furthermore, since the screw is fixed in the middle of the capillary action blocking gap, water will not penetrate into the window frame side through the screw penetrating portion.

As described above, the window frame body is selected depending on the type of fittings 43 to be built therein (in the illustrated example, a hinged door is accommodated), and the fixed frame is connected around the window frame body to form the window frame. , which is fitted into the window opening and attached to the first and second mounting edges 34, 35.
Window opening forming frame 2 with screws, nails, etc. 32, 33
It is attached by fixing to 9-31. Since both frames of the fixed frame are fixed with screws, nails, etc. at the same first and second mounting edges, it is easy to install the window frame.

Further, since each fixed frame has an exterior parting edge 39 extending from the first mounting edge 34 to the outdoor side, parting finishing can be performed without using other parting members when constructing the exterior 44. Because it can be done, the construction of the parting can be done easily and beautifully.

As described above, according to this invention, the connection between the fixed frame and the window frame body can be made simple and strong, and the fitting groove formed between the protrusions provided on the connecting board of the fixed frame can be easily and firmly connected. The outer circumferential portion of the window frame body is fitted, and the groove provided in the window frame body forms a capillary action blocking gap, so even with a simple connection structure by fitting and screwing, the fixed frame and window frame can be connected by capillary action. Rainwater can be prevented from entering between the main body and the main body. Furthermore, since grooves are provided on the inside and outside of the screw-fastening portion, the capillary action blocking effect is ensured.
