Description

[Detailed description of the invention] This invention connects a window frame assembled with a shape extruded from aluminum or aluminum alloy and a decorative rim attached to the indoor side of the window frame to prevent heat conduction, and This invention relates to a device for connecting a window frame and a decorative edge in which screws connecting the frame and the decorative edge are not exposed to the outside.

As is well known, when a window frame assembled from light metal extrusions is attached to a window sill, the width of the window sill is wider than the width of the window frame.
Since the indoor side of the window sill is exposed, the exposed surface of the window sill had to be finished beforehand, or the exposed surface of the window sill had to be hidden afterwards with a decorative border.

However, if you connect a metal decorative frame to the window frame to hide the exposed surface of the window sill, the connecting screws will be exposed to the outside and look unsightly, and the window frame and the decorative frame may conduct heat. Another disadvantage was that condensation formed on the decorative edges, polluting the room.

Therefore, this idea was developed to connect the metal window frame and the metal decorative edge with an insulating sleeve interposed so that they do not touch directly, and to connect the screws that connect the window frame and the metal decorative edge in an insulated state to the insulating material. It is designed so that it can be hidden by a shield.

Next, the structure of the connecting device according to the present invention will be explained with reference to drawings of embodiments.The upper and lower frames F constituting the window frame frame F1. The inner wall 11.12 of F2 has a protruding strip 21.22 that protrudes toward the interior of the room from the tip of the inner wall 11.12, and the protruding strip 21.22
Joint walls 31.32 extending toward the interior of the room from the lower inner walls 11.12 are provided parallel to the longitudinal direction of the upper and lower frames F, F2, and the left and right short frames F3. The inner wall 13.14 of F4 is also provided with a convex strip 23.24 projecting toward the interior of the room from the inner wall 13.14 and joining walls 33, 34, and the upper and lower frames F1. F2 and left and right short frame F3. On the inner wall 1 of the window frame F assembled by F4, a protruding strip 2 protrudes toward the interior from the inner circumferential side of the inner wall 1, and a joint extending from the inner wall 1 on the outer circumferential side of the protruding strip 2 toward the indoor direction. While the wall 3 is provided, a connecting wall 6 of the decorative edge 5 connected to the window frame F has a protruding strip 7 opposite to the protruding strip 2 provided on the inner wall 1 of the window frame F, and a connecting wall 6 of the decorative edge 5 connected to the window frame F. A connecting wall 8 is formed which overlaps the connecting wall 3 provided on the inner wall 1 of the frame F in a staggered manner, and an appropriate number of insertion holes 4 for sleeves S made of a heat insulating material are provided in the connecting wall 8 of the decorative edge 5. A small hole 9 communicating with the fitting hole 4 bored in the connecting wall 8 of the decorative rim 5 is provided in the connecting wall 3 of the window frame F that overlaps the connecting wall 8 of the decorative rim 5, so that the connecting wall 8 of the decorative rim 5 can be inserted. Thread the screw B into the small hole 9 drilled in the joint wall 3 of the window frame F from the sleeve S inserted into the hole 4,
Either the window frame F and the decorative rim 5 are connected and fixed in a thermally insulated state, or the connecting wall 3 protruding from the inner wall 1 of the window frame F as shown in FIG. Formed on the inner peripheral side of the wall 8, a fitting hole 4 for the sleeve S is provided in the joint wall 3 of the window frame F, and a connecting wall 3 of the decorative edge 5 that overlaps the joint wall 3 of the window frame F,
A small hole 9 communicating with the fitting hole 4 of the window frame connecting wall 3 is provided, and a sleeve S inserted into the fitting hole 4 of the window frame connecting wall 3 connects to the small hole 9 bored in the connecting wall 8 of the decorative edge 5. Screw in the screw B to connect and fix the window frame F and the decorative edge 5 in a thermally insulated state, and connect the protruding strip 2 provided on the inner circumferential side of the joining wall 3 of the window frame F to the protruding strip 2 facing oppositely. A shield T made of an elastic heat insulating material is fitted and locked between the protrusion 7 of the decorative rim 5, and the connecting wall 3 of the window frame F and the connecting wall 8 of the decorative rim 5 are connected. A connecting wall 3 that protrudes from the inner wall 1 of the window frame F, and a decorative edge 5 that overlaps the connecting wall 3 in a staggered manner.
The connecting wall 8 is formed so as to be overlapped with an appropriate distance H apart from the connecting wall 8 so as not to come into direct contact with each other.

Since the device for connecting the window frame and the decorative edge of the present invention has the above structure, first, attach the inner wall 1 of the window frame F to the window sill facing the indoor side,
Next, connect the connecting wall 6 of the decorative edge 5 toward the outdoor side from the indoor side of the window sill.

At that time, the connecting wall 3 extending indoors from the inner wall 1 of the window frame F and the connecting wall 8 provided on the connecting wall 6 of the decorative rim 5 are spaced at a distance H.
are overlapped with each other, and the protruding stripes 2 protruding from the inner wall 1 of the window frame F and the protruding stripes 7 provided on the decorative edge 5 are attached so as to face each other.

After installing the window frame F and the decorative frame 5, insert the insertion hole 4 into the connecting wall 8 of the decorative frame 5, and the connecting wall 3 of the window frame F that overlaps with the connecting wall 8.
Before drilling a small hole 9 that communicates with the fitting hole 4 or attaching the decorative edge 5, the fitting hole 4 is previously drilled in the connecting wall 8 of the decorative edge 5, and the decorative edge 5 is attached; After that, small holes 9 are bored in the connecting wall 3 of the window frame F from the fitting holes 4 provided in the connecting holes 8 of the decorative rim 5, and holes 9 are made in each fitting hole 4 provided in the connecting wall 8 of the decorative rim 5. While inserting the sleeve S, insert the screw B into the small hole 9 of the window frame joint wall 3 from the sleeve S.
If you screw in and connect and fix the window frame F and the decorative edge 5, the window frame F
The connecting wall 3 of the decorative edge 5 and the connecting wall 8 of the decorative edge 5 overlap with each other with a distance H apart, and the screw B screwed into the connecting wall 3 of the window frame F from the connecting wall 8 of the decorative edge 5 is inserted into the connecting wall 8. Since the sleeve S of the heat insulating material inserted into the hole 4 is screwed into the small hole 9 of the window frame joining wall 3, no heat conduction occurs between the window frame F and the decorative edge 5.

After the connecting wall 3 provided on the inner wall 1 of the window frame F and the connecting wall 8 provided on the connecting wall 6 of the decorative edge 5 are connected and fixed by the heat insulating structure as described above, A shield T made of an elastic thermal material is fitted and locked between the protruding strip 2 of the window frame F and the protruding strip 7 of the decorative edge 5, and the screw B is hidden from view from the outside. This is what I did.

Therefore, if the proposed connecting device is used at the connecting part between the window frame and the decorative edge,
Even if the window frame and the decorative rim are both made of metal, the connecting wall on the inside wall of the window frame and the connecting wall on the decorative rim overlap with a gap between them, and the connecting wall of the decorative rim overlaps the window frame. The screws that are screwed into the connecting wall of the window frame, or the screws that are screwed into the connecting wall of the window frame and the connecting wall of the decorative rim, are inserted through a sleeve made of heat insulating material, so there is no space between the window frame and the decorative rim. There is no heat conduction, and no condensation occurs on the decorative edges of the interior due to heat conduction.

In addition, the screws that connect and fix the window frame and decorative rim to the heat-insulating structure are hidden by a protruding strip provided on the window frame on the inner peripheral side of the connecting portion and a shield that locks between the protruding strips provided on the decorative rim. As a result, the appearance of the connecting part also becomes very good.

Furthermore, when the proposed connecting device is put to practical use, when extrusion molding the constituent materials of the window frame, the convex strip and the joint wall are integrally formed on the inner wall of each frame, and the constituent materials of the decorative rim are extruded. In this case, since the protrusion and the connecting wall can be integrally formed on the connecting wall, the sleeve and shield are manufactured separately, and the insertion hole for the sleeve is made in the connecting wall of the decorative rim, and the insertion hole of the sleeve is made in the connecting wall of the window frame. The window frame and the decorative rim can be connected and fixed to the heat insulating structure by simply drilling a small hole that communicates with the insertion hole in the decorative rim connecting wall, and the connection method is simple. .
