Description

[Detailed Description of the Invention] This invention relates to an inner lintel used in a split type double sash, that is, a type of double sash that connects an inner sash and an outer sash that are assembled separately.

Satsushi with tiered windows requires a middle lintel.

In order to provide a step window in a split type double sash, it is possible to provide a step window in both the inner sash and the outer sash, or in either one of them.

In general, the inner and outer lintels have a larger area of air contact both indoors and outdoors than other window frame members.

Therefore, especially when installing step windows on both the interior and exterior sashes, consideration must be given to preventing condensation on the inner lintel.

In this way, when installing step windows on both the inner and outer sashes of a split type double sash, the configuration in which the inner lintels of each sash are connected depends on the difficulty of connection, connection strength, heat insulation, waterproofness, and vibration proofing. It affects the quality of sexuality, etc.

The purpose of this invention is to provide a double sash inner lintel for a split type double sash that allows easy connection of the inner lintels for each inner and outer sash, provides great connection strength, and has excellent lighting performance.

The inner lintel according to this invention consists of an inner satsuri rain lintel 1 and an outer satsuri inner lintel 2, and the inner satsuri rain lintel 1 has a pair of upper and lower connecting edges 1e and I that protrude toward the outdoors from its outdoor side.
f, and the outer sash inner lintel 2 has a pair of upper and lower connecting edges 2e, 2f that protrude toward the interior from the indoor side surface, and in order to connect these to form a double sash inner lintel, an outer sash is required. The basic configuration is to fit the connecting edge of the inner lintel between the connecting edges of the inner lintel, and to connect the upper connecting edges and the lower connecting edges, respectively. This allows the inner and outer rain lintels to fit together well when they are fitted together, and makes it easier to connect them.Furthermore, the top surface of the outer and inner rain lintels is lower than the top surface of the inner and inner rain lintels. To improve drainage performance from the upper surface of the indoor side end to the outdoor side end, and in addition, to improve the lighting performance of the window and the sense of openness by making the lower surface of the outer sash rain lintel higher than the lower surface of the inner sash rain lintel. It has the advantage of being easy to do.

Next, an embodiment of this invention will be described in detail based on the drawings.

The inner Satsushi rain lintel 1 has an indoor wall 1a, an outdoor wall lb,
The upper wall 1C and the lower wall 1d are integrally formed into a rectangular tube shape, and the upper wall 1C has an upper shoji d1. Rails 1r1 and 1r2 are protrudingly provided as a means for holding d2, and lower shoji d3. A guide groove g19g2 is provided as a means for holding d4.

With this invention, the inner satsui rain lintel 1 has a pair of upper and lower connecting edges 1e and I that protrude toward the outdoors from the outdoor side surface.
f is provided along the entire length of the middle lintel.

As in the preferred example illustrated, the upper connecting edge 1e is formed by continuously extending the upper wall 1C in the outdoor direction, or is formed at a position lower than the earthen wall, and the lower connecting edge 1f is formed by a guide groove g2 on the lower surface. A dovetail groove 1h is formed in the upper surface of the lower connecting edge 1f, which projects toward the outdoors from the hanging wall 1g forming the lower connecting edge 1f, and a heat insulating packing S1 that projects upward from the lower connecting edge is fitted into the dovetail groove 1h. has been done.

This heat insulating gasket S1 is made of a material such as rubber or plastic that has a small thermal conductivity coefficient and has appropriate elasticity, and extends over a length equal to that of the inner lintel.

After the heat insulating packing S0 is fitted, screw insertion holes are formed in the lower connecting edge 1f and the heat insulating packing S2 at equal positions in the vertical direction at predetermined intervals in the longitudinal direction.

This inner sash rain lintel 1 abuts its longitudinal ends against both vertical bars (not shown) of the inner sash, respectively, and screw holes 11 provided in the upper wall 1C and the lower wall 1d from the outside of each vertical frame. By screwing a tapping screw into the screw hole 11, the inner sash is connected and fixed between both frames in a state parallel to the upper and lower frames (none of which are shown), thereby forming an inner sash with a transom.

In addition, the outside satsui rain lintel 2 has a rectangular tube shape with an indoor wall 2a, an outdoor wall 2b, an upper wall 2C, and a lower wall 2d, and the upper wall 2C
There is an upper shoji d5. d6 holding rail 2 rl, 2
r2 is provided protrudingly, and a lower shoji d7 is provided on the lower surface of the lower wall 2d. d
8 holding guide grooves 2g1 and 2g2 are provided.

Then, each connecting edge 1 of the inner satsushi rain lintel is placed on the side of the room.
A pair of upper and lower connecting edges 2e and 2f protruding toward the indoor direction are provided corresponding to e and If.

The upper connecting edge 2e is, for example, formed by continuously extending the upper wall 2C in the indoor direction, and is provided with a dovetail groove 2h that opens upward on its upper surface, and a heat insulating material similar to the heat insulating packing S1 is provided in the dovetail groove 2h. The gasket S2 is fitted so as to protrude upward, and screw insertion holes passing through the upper connecting edge 2e and the heat insulating gasket S2 in the vertical direction are provided at predetermined intervals in the longitudinal direction, as described above.

The lower connecting edge 2f is provided to protrude toward the interior of the room from the hanging wall 2g forming the guide groove 2g1.

This outside satsushi rain lintel 2 also uses one screw hole 21,
Like the inner sash rain lintel 1, it is connected and fixed between both vertical frames of the outer sash in parallel with the upper and lower frames (not shown) to form an outer sash with a transom.

The distance from the upper surface of the heat insulating gasket S2 of the outer sash rain lintel 2 to the lower surface of the lower connecting edge 2f is slightly smaller than the distance from the lower surface of the upper connecting edge 1e of the inner sash rain lintel 1 to the top surface of the insulating gasket s1. The distance between the pair of connecting edges 1e, If, 2e, and 2f of each middle lintel is set so as to be large.

In this way, the window connecting the inner sash and the outer sash has a pair of upper and lower connecting edges 2e and 2f of the outer sash rain lintel 2 for the inner sash and a pair of upper and lower connecting edges 1e and 2f of the inner sash rain lintel 1. The upper connecting edge 1e of the inner sash rain lintel is brought into close contact with the upper surface of the insulation gasket S2 of the outer sash rain lintel with the insulation gasket pressed, and the lower connecting edge 1e of the outer sash rain lintel 2f is brought into close contact with the upper surface of the insulation packing S1 of the inner sash rain lintel in the same state, and the screw nl inserted into the insertion hole provided in advance in the upper connecting edge 1e is inserted into the insulation packing S1.
2 and screwed into the hole provided in the connecting edge 2e, and similarly, by inserting the screw n2 through the hole provided in the lower connecting edge 1f and the heat insulating packing S1 and screwing it into the hole previously provided in the connecting edge 2f, A heat insulating gasket S2. Connect via Sl.

In this case, the connecting edges 1e, 2e, If, 2f are drawn to each other by tightening the screws nl, n2, respectively, so that the heat insulating gasket S2. Sl is strongly pressed and brought into close contact with the connecting edge.

Therefore, the inner sash rain lintel 1 and the outer sash rain lintel 2 are the insulation pads S1. S2 reliably blocks heat conduction and forms a sealed insulating space S between the rain lintels, providing high insulation performance for the double sash inner lintel and preventing condensation on the inner sash rain lintel. It is possible to prevent this and reduce the cooling load.

In particular, the upper connecting edges 1e and 2e of the rain lintels 1 and 2
Since the space between the connecting edges 1e and 2e is sealed by the heat insulating gasket S2, rain that falls on the upper surface of the inner lintels 1 and 2, or condensed water that drips on the transom shoji, will infiltrate from between the connecting edges 1e and 2e. This prevents rain from occurring and provides excellent rain protection.

In addition, the connecting edge 2e of the outer sash rain lintel is provided on the extension of the upper wall 2C in the indoor direction, and the connecting edge 1e of the inner sash rain lintel is provided on the outdoor extension of the upper wall 1C, and the upper side of the former connecting edge 2e When the latter connecting edge 1e is superimposed on the connecting edge 1e and the heat insulating gasket S2 is interposed between them, and the screws nl are used to tighten them, the heat insulating gasket S2 not only seals the space between the two fastening edges, but also the heat insulating gasket S2 Since the connecting edge 1e forms a rain return, it is no longer necessary to erect a weir wall on the outside rain lintel as in the past, and therefore the height of both the inside and outside middle lintels is reduced. Therefore, it is also possible to increase the opening area of the upper window (transom).

In order to prevent rainwater from entering from the connection part of the upper connecting edges 1e and 2e of the rain lintels 1 and 2, the upper connecting edges 1e of the inner satsuri rain lintels are protruded on an extension of the upper wall 1C or below it. , the upper connecting edge 2e of the outside rain lintel is the upper wall 2
It is necessary to protrude on the extension of C or above it.

In this design, the upper and lower connecting edges of the outer satsuri rain lintel are fitted between the upper and lower connecting edges of the inner satsuri rain lintel.
It is easy to meet the above needs, and there is a lintel in the rain.
, 2 is formed in a downwardly sloping or stepped shape toward the outdoors, and by making the outdoor side lower than the indoor side, drainage performance can be easily improved.

In addition, the upper and lower connecting edges of the outer satsuri rain lintel fit between the connecting edges of the inner satsuri rain lintel, so the lower shoji guide grooves 2gl and 2g2 of the outer satsu rain lintel are connected to the lower shoji shoji of the inner satsuri rain lintel. Guide grooves 1g+ and 1g2 are easier to install above, so the vertical dimensions of the outer sash rain lintel are smaller than those of the inner sash rain lintel, increasing the amount of light and giving the window a sense of openness. be able to.

Note that the heat insulating gasket may not be fixed in advance, but may be done by simply sandwiching the connecting edges and fastening the connecting edges together with screws, or as shown in Fig. 2,
Dovetail grooves 3h and 4h are provided which open facing each other on the connecting edges 3e and 3f of the inner sash rain lintel and the connecting edges 4e and 4f of the outer sash rain lintel, respectively, and double-speed lintels 3e and 4e are provided.
, 3 f, and 4 f are arranged one above the other, and the heat insulating gasket S1. By slidingly fitting S2, the heat insulating gasket may be attached and the connecting edge may be connected at the same time.

As mentioned above, the double satsushi rain lintel created by this invention is
A pair of upper and lower connecting edges protruding toward the indoors from the indoor side of the outer satsuri rain lintel are fitted between a pair of upper and lower connecting edges protruding toward the outdoors from the outdoor side of the inner satsuri rain lintel, and the upper connecting edge Since the upper and lower connecting edges are connected to each other, the inner and outer rain lintels fit well in the connected state, making the connection work easy and providing high connection strength.

In addition, since the connecting edge of the outer satsuri rain lintel fits between the connecting edges of the inner satsuri rain lintel, the upper surfaces of the inner satsuri rain lintel and the outer satsuri rain lintel are lowered from the indoor side toward the outdoor side. In addition, the lower surface of the outer open rain lintel can be easily raised higher than the lower surface of the inner open rain lintel, so this inner lintel improves drainage and lighting, and provides a sense of openness. can.
