Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention relates to a wooden exterior sash having a novel structure developed for use as exterior fittings for buildings, particularly wooden buildings.

(Prior Art) As for the exterior sashes of recent buildings, aluminum sashes are now at their peak, replacing the wooden fittings and steel sashes of the past. This aluminum satsushi is
It is easily realized by combining mold materials mass-produced by extrusion molding, and has the characteristics of excellent rain protection and airtightness. It has drawbacks such as poor appearance. Regarding alkali resistance, surface treatment technology has recently been established, and fairly reliable aluminum sashes have become commercially available.However, regarding other points, for example, aluminum sashes that are colored to cover up poor appearance Although it has become available in large quantities, it still cannot match the natural beauty, and has the disadvantage that the higher the quality, the more expensive it becomes. Including the above, these were not necessarily ideal fittings for traditional Japanese wooden buildings.

Despite this situation, aluminum satsushi still accounts for almost 100% of wooden construction fittings.
The reason why this situation is unlikely to change in the future is that aluminum satsushi industry has achieved a penetration rate close to that of aluminum satsushi, and the reason why it is unlikely that this situation will change in the future is because of the aluminum satsushi industry's continuous product development efforts and advertising effects. This is probably because the environment has been created to such an extent that it is impossible for satsushi to be made of these materials. The people who have sided with the creation of this kind of environment are none other than the group of wooden joinery craftsmen who have built a traditional position in our country. This can be said to be the result of neglecting to develop products that take advantage of this, let alone making any effort to promote them.

In response to such a situation, this invention uses wood, especially cypress wood and other high-quality woods.It is made of wood that is as durable as aluminum sash, and that is comparable in other properties to aluminum sash. The exterior sash has been successfully developed and put into practical use, and its configuration is as detailed below.

(Structure of the Invention) As understood from the drawings shown as some embodiments, the present invention basically consists of a wooden inner frame 1
and a wooden peripheral frame 2.

The wooden inner frame 1 frames the outer periphery of the glass plate 3 with packing material 4 interposed on the periphery.
It is formed so that it can be assembled and disassembled with screws 11 etc. near each corner.

The wooden peripheral frame 2 consists of a pair of upper and lower horizontal frames 21, 22 and a pair of left and right vertical frames 23, 24, each frame having inner frame fitting grooves 25, 25, . . . formed inside thereof. The lower ends of a pair of left and right vertical frames 23 and 24 are combined with both ends of the lower horizontal stile 22 so as to be freely expandable and openable. At this stage, communicating inner frame fitting grooves 25, 25, 25 are realized inside the pair of left and right vertical frames 23, 24 and lower horizontal frame 22.

While slightly widening the upper ends of the left and right vertical frames 23 and 24 of the wooden peripheral frame assembled in this way, the wooden inner frame 1 integrated with the glass plate 3 assembled earlier is inserted into the inner frame fitting groove 25 from above. , dropped to 25,
After that, while fitting the inner frame fitting groove 25 of the upper horizontal stile 21 to the upper edge of the inner frame 1, both ends thereof are detachably assembled to the upper ends of the pair of left and right vertical frames 23, 24,
The outside of the wooden inner frame 1 is the wooden fitting groove 2 of the wooden peripheral frame 2.
To realize a wooden exterior sash in a state completely fitted to 5, 25, 25, 25.

(Example 1) FIG. 2 shows a specific combination of a horizontal stile and a vertical stile according to the present invention, and a central vertical sectional view of a fixing structure. As you can see from this cross-sectional view, the horizontal stile 2
A handle 26 is formed at both ends of the vertical stile 23, and a screw receiving fitting 28 is screwed so as to fit within the bottom surface of the inner frame fitting groove 25. After fitting the handle 26 of the horizontal stile 21 into the
A threaded rod 29 is inserted, and its tip is screwed into the screw receiving fitting 28 and fixed.

The upper and lower pair of horizontal stile 21 and 22 may be formed of the same structure as above, but the lower horizontal stile 22 and the vertical stile 2
The combination structure with 3 and 24 is the handle 26 and handle hole 2.
7, for example, as shown in FIG.
a in advance, or by forming a step 26a on the handle 26 as shown in FIG. It is possible to realize an expansion movement. In the figure, 5 indicates a blind cap for the threaded rod 29.

(Example 2) FIG. 5 shows a cross-sectional view showing a horizontal cross section of the vertical stile 23. As can be understood from this sectional view, the cross-sectional shape of the wooden inner frame 1 has a stepped portion 12 formed between the glass plate receiving side cross-sectional part and the inner frame fitting groove fitting side cross-sectional part of the wooden peripheral frame 2. and this step 1
2 makes it easy to fit the wooden inner frame 1 into the wooden surrounding frame 2 (the outer surface of the wooden inner frame 1 bites into the bottom of the inner frame fitting groove of the wooden surrounding frame 2,
In addition to preventing the phenomenon of getting stuck, it also improves the aesthetic appearance after completion, and further improves the appearance of the wooden inner frame 1 and the wooden peripheral frame 2.
It functions to hide the occurrence of gaps between the layers. in this way,
Although it is possible to realize a more advantageous wooden exterior sash by making the wooden inner frame 1 have a stepped cross-sectional shape, the present invention is not necessarily limited to this embodiment, as shown in the perspective view of FIG. It goes without saying that the wooden exterior sash which is the object of the present invention can be realized even with such a cross-section with no steps.

(Example 3) FIG. 6 shows a horizontal sectional view of this wooden exterior sash at the time of installation. As understood from this example, a pair of left and right stiles 2
By forming a groove on the outer side of each door contact surface of Nos. 3 and 24, a protrusion 23a or 2 is formed on both ends of the groove.
4a, while the same protrusion 23a is provided on the frame material 7 side.
Or parallel strips 71 for receiving 24a,
71 to improve the airtightness of the wooden exterior sash of the present invention, and one side of the vertical stile in the overlapped part of the sashes is filled with an airtight material 6 made of mohair or the like to improve airtightness at the same place. It is possible to adopt a configuration that ensures the following.

(Function and Effect) The wooden exterior sash of the present invention having the above-described structure is composed of a wooden inner frame that fixes the outer periphery of the glass plate, and a wooden peripheral frame that is separate from the inner frame. Therefore, especially when used as exterior sash for wooden buildings, first of all, due to the characteristics of the material, the appearance is much more harmonious compared to recent colored aluminum sashes. In addition, because of its good insulation properties, there is no risk of condensation on the sash surface during heating or cooling, and it is extremely advantageous in terms of heat loss. Furthermore, since excellent antiseptic paints have already been developed, they do not rot like they did a few years ago, and there is of course no risk of corrosion due to air pollution, and there is no risk of salt damage. It has many characteristics, such as being able to maintain its original properties even when used without distinction in any natural environment, and being superior to, but never inferior to, aluminum satsushi in terms of durability. .

Furthermore, from a structural point of view, since the outer periphery of the glass plate is handled with the outer periphery of the glass plate bordered in advance by a wooden inner frame, assembly and disassembly are extremely simple. This is a very clear distinction when compared to the assembly and disassembly of aluminum sash frames, considering that even highly skilled sash craftsmen need a certain amount of know-how to assemble aluminum sash frames while fitting rubber packing around the outer periphery of the glass plate. be done. In particular, when the vertical stile and horizontal stile are combined and the fixing structure is a structure in which the screw receiving metal fitting 28 and the handle 26 are used in combination as shown in Example 1, it becomes even simpler and more reliable.

Furthermore, there is no possibility of accidentally damaging the outer periphery of the glass plate or injuring the operator during the handling process, thereby increasing safety from both points of view.

On the other hand, since the left and right vertical frames are constructed to be able to expand and open, the main feature is that the wooden inner frame with the glass plate can be inserted and removed very smoothly. This feature is further enhanced because both the peripheral frame and the inner frame are made of the same material, wood, and are slidable. In particular, this effect
The cross-sectional shape of the wooden inner frame 1 shown in Example 2 is
If you stand on something with a step, this step will function as a guide and become more noticeable.

Furthermore, as a result of dividing the functions between the wooden inner frame that fixes the glass plate and the wooden surrounding frame that fits the wooden inner frame, it has an excellent feature that almost no wobbling occurs even if it changes over time. It will play out its characteristics. In particular, the cross-sectional shape of the wooden inner frame 1 according to the second embodiment is adopted, and the frame member 7 is formed with a vertical stile having protrusions 23a, 24a and parallel strata 71, 71 for receiving the vertical stile as in the third embodiment. If this is adopted and the airtight material 6 is also used, there will be no loss in terms of airtightness compared to aluminum sash.

As mentioned above, the wooden exterior satsushi of this invention is
This is not just a matter of replacing aluminum with wood, but a structure that matches the properties of wood to create a sash that can compete with aluminum sash. With the addition of the advantages of the material, it should be able to demonstrate its power greatly as an exterior sash for buildings in Japan. On the other hand, it will also contribute to the creation of kirigake that will once again revive the skills of wooden joinery craftsmen, who are an excellent technical group in Japan.
