2. Description of the Related Art To date, school buildings in Japan have been constructed not only during the rush of construction of new school buildings as a measure against the sudden increase in the number of children, but also as a measure to consolidate schools due to a decrease in the number of children. Even in construction, most of them
Reinforced concrete construction, which has excellent durability and is also highly regarded in terms of safety, has become the mainstream.However, in this reinforced concrete construction, due to the attributes of the material and the structural form, summer without air conditioning equipment is required. Is hot, cold in winter and extremely difficult to spend, and the reverberation of the sound is too large to make it a natural conversation, the impressions received by the five senses, the touch feeling is cold and hard, etc. , They have a considerable impact on the educational setting,
It reduces attention and concentration during class and leads to fatigue of educating teachers, causing educational problems such as bullying and class collapse, and hindering healthy development of school children. As the educational environment, including school buildings, is being reviewed due to strong reflection, the effectiveness of wooden buildings with a long history in Japan has been reaffirmed. Elementary and junior high school buildings, where compulsory education is practiced, are all wooden school buildings, and even though they are mainly reinforced concrete or steel frames, they have transformed into school buildings that use abundant wood, and many wooden school buildings or similar ones Has been built.

[0003] In addition to the evaluation in terms of the educational environment, such a tendency has been noted in recent years that, in recent wooden buildings, seismic resistance, corrosion resistance, fire prevention performance, and the like have been dramatically improved due to improvements in design techniques and bonding techniques. Adoption of glued lumber makes it possible to produce curved surfaces that are not inferior to reinforced concrete structures, and the degree of freedom in design has been increased.Therefore, construction of buildings that are extremely excellent in terms of structural strength and design is also possible. It is possible, and various functions such as safety are required, and it is thought that the technical backing that can sufficiently cope with the architectural structure of a large school building building is also a great driving force. Can be

[0004] In a wooden or similar school building, due to the nature of the wood material, it is possible to obtain moderately warm and cool sensation, soft and warm touch, etc. as well as beautiful grain with beautiful luster, warm and comfortable colors and calm saturation. And enjoy natural conversation with better sound absorption and reverberation, and bring about the stabilization of the soul by the fragrance of wood, etc., enrich the emotions through sight, touch, hearing, smell, etc., and reduce mental anxiety and fatigue. With a near-ideal container that can be relaxed and made to feel relaxed and a healthy educational environment for children, it is possible to use metal desks, chairs and shelves as before. In addition to personal accessories such as etc., the adoption of steel or aluminum window frame sashes and doors has been shunned, and the use of wooden desks and chairs has been rapidly increasing. It is fit.

[0005] However, when the metal window frame sash is made of wood, the material of the metal sash has too much variation as compared with the metal, leaving a problem in airtightness and rain-closing structure.
Some of the structural technical difficulties caused by the material, such as the need to resolve management issues, must be eliminated, especially in large windows such as auditoriums and gymnasiums. In the case of, in many cases it is necessary to adopt a vertically long sliding door instead of a sliding door due to safety in opening and closing and design requirements, which is more difficult than a sliding door in structural technology The problem, that is, the window frame sash for a sliding door, which can move stably with the structure in which the sliding door has its own weight supported by the rail on the lower end side, whereas the sliding door has a loose fit in the left and right grooves. In the structure that moves the fittings up and down, since the window fittings must be combined with the window frame with the loose fitting structure, play to enable the vertical movement of the window fittings to the left and right is indispensable, The play easily causes rattling and it is difficult to secure airtightness On the Kunar, we are racking the nasty problem of such results in disturbed to move up and down in the deformation of the window joinery, therefore, for this up and down argument difference door is,
In particular, it is difficult to adopt it in school buildings such as elementary and junior high schools where high durability, airtightness and operability are required, and at best, as a window frame sash for sliding doors up and down, the surface of metal sash In fact, it was necessary to apply a synthetic resin coating to the wooden school building so that the wooden school building could be handled in a way that would not cause any discomfort.

According to the present invention, as described above, in a wooden window frame sash, particularly a window frame sash for a sliding door, a wooden material is difficult to prepare a homogeneous material, and furthermore, in addition to the attribute of the material, it is easy to deform. Due to the peculiarity of the target window frame structure, there is a stereotype from the past that it is likely to gradually rattle due to long-term use, and it is too strong to impair the maintenance and management. In view of the fact that adoption in school buildings is being refrained, realization of window frame sashes for vertically sliding doors that can satisfy various conditions, especially window frame sashes for sliding doors suitable for using wooden materials As a result of repeated development and trials and many trials and experiments over a long period of time, the new window frame sash for sliding doors with a new structure has finally been developed. It is obtained by successfully completing a vertical pull difference windows novel structure using, in the following, with examples representative of the present invention shown in the drawings, and specifically described the configuration.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments shown in the drawings, which are representative of the present invention, the window frame sash for a sliding door included in the present invention basically has the following structure. It is a gist. That is, a fixed frame portion having an assembling groove is attached to each of the peripheral surfaces of the opening frame formed in the building opening, with the opening direction of the groove being directed toward the center of the opening frame, A rail frame portion having a fitting groove having a width capable of receiving the edge side of the window fitting which must be accommodated in each of the fixing grooves of these fixed frame portions is incorporated into the window frame main body.

This is a window frame sash for sliding doors that is vertically controlled by a structure in which the rail frame part built into the mounting groove of the fixed frame part is constantly biased toward the center of the open frame body by the elastic force of the material part. .

The above-described window frame sash for a vertically sliding door according to the present invention having the above-mentioned basic structure is characterized in that the fixing frame portion having an assembling groove is provided on each of the inner peripheral surfaces of the opening frame formed in the opening of the building. Can be installed with the opening direction of the groove facing the center of the opening frame body, and the mounting groove of these fixed frame parts can accept the edge side of the window fittings that must correspond to each Incorporating the rail frame portion formed with a fitting groove having a width of the window frame body into the window frame main body, and incorporating the rail frame portion into at least one of the right and left fixed frame portions in the window frame main body, The rail frame portion, which is assembled into the mounting groove of the fixed frame portion by the resilience of the resilient material portion, is always opened frame by interposing an elastic material portion between the fixed frame portion and the rail frame portion. Regulated to a structure biased toward the body center, the rail frame A sliding door window having a structure in which the groove bottom of the mating groove can be pressed against and abutted against the edge of the window fitting, and the gap between the window frame body and the edge of the window fitting is formed airtight. It can also be called a frame sash.

Further, as a more specific configuration, the window frame sash for a vertically sliding door according to the present invention has an assembling groove on each of the inner peripheral surfaces of the opening frame inside the opening of the building. The fixing frame portion is attached in a state where the opening direction of the groove is directed toward the center of the opening frame body, and the assembling groove of the fixing frame portion has to correspond to the edge side of the window fitting which must be respectively corresponded. Into the window frame main body by incorporating a rail frame portion formed with a fitting groove having a width capable of receiving the rail frame portion with respect to one or both right and left fixed frame portions of the window frame main body. The assembling structure combines the elastic frame portion between the fixed frame portion and the rail frame portion, and with the elastic force of the elastic material portion, the rail frame portion incorporated in the mounting groove of the fixed frame portion. , A structure that is regulated to a structure that is always biased toward the center of the open frame Up-and-down argument difference door window frame sash to the subject matter of the present invention.

[0010] The opening of the building mainly functions as a ventilating port and the intake of outside light and outside air, and also shares a design function as a part of the building, such as a sliding door or a sliding door. Like the part where the fittings are provided, it is provided in a penetrating manner outside the outer wall part of the building, in the room and corridor, or in the wall part in the building that separates the room and the room, inside the opening part, In general, a frame on the skeleton side where upper and lower, left and right frame members are attached and formed in a vertically long rectangular building opening so that the window frame sash for a vertically sliding door of the present invention can be incorporated. It is a structural part.

The window frame body is disposed and fixed inside the above-mentioned building opening, and is fitted and supports a pair of upper and lower window fittings, which will be described later, which are guided up and down by a track shifted forward and backward. An opening frame that is a part that performs a function and is attached to and fixed to the inner peripheral surface of the building opening, and a fixed frame that is attached to the opening frame and receives and supports a rail frame described below. Department,
And, in the state of being combined with the fixed frame portion, each of the right and left edge grooves or ridges of the window fitting which must correspond to each other is guided to realize vertical sliding without detachment of the window fitting. And the rail frame to be
When used for wooden buildings, at least the open frame should be made of natural wood or laminated wood, but in some cases, it may be made of aluminum or steel or plastic molds that have been subjected to decorative finishing such as baking coating. It is also possible that the fixing frame part is incorporated in a part of the opening frame body, in other words, a groove for receiving the rail frame part in the cross-sectional structure of the opening frame body. Or a ridge or other appropriate receiving structure.

The opening frame is attached to and fixed to the inner peripheral surface of the building opening, and has a function of attaching and supporting a fixed frame for fitting and supporting a pair of upper and lower window fittings. As described above, when used for a wooden building, it is to be formed of a wooden plank, and at the place where the fixed frame portion is attached on the inner peripheral surface side, the side surface of the fixed frame portion is It should be formed in a groove structure that makes the whole of the fixed frame part buried so as not to be exposed to the outside, and nails and dowels along with water-resistant adhesive are attached to the inner peripheral surface of the building opening. It must be firmly integrated by using a dowel, a jewel or other appropriate means.

The fixing frame portion has an assembling groove formed on the side opposite to the surface to be attached to the opening frame, that is, toward the center of the building opening, and is substantially parallel to the assembling groove. The rail frame portion can be loosely fitted to the fixed frame portion so that the rail frame portion can only move inward (toward the center) of the building opening in a state where displacement in the front-rear direction is regulated. On the other hand, the rail frame portion is formed with a fitting groove having a width capable of receiving the edge side of the window fitting, which must correspond to each other. After being directed toward the inside of the opening, at least one of the left and right, or between the rail frame portion and the fixed frame portion disposed on both the left and right, a predetermined portion such as a spring, a sponge body, a soft rubber body, or the like. With a structure with elastic material part interposed in the fixed frame part mounting groove The distance between the rail frames when fitted and when no load is applied to the resilient material shall always be maintained at a dimension that is somewhat smaller than the width of the window fittings that must be accommodated. Must also
When the window fittings are fitted by forcibly expanding the space between the rail frame parts set to the somewhat smaller dimensions, each of the window fittings of the rail frame part which comes into contact with both end surfaces of the window fittings. The pressing force of the resilient material portion which presses the edge surface and makes it close contact is less likely to hinder the vertical movement of the corresponding window fitting, and is an optimal degree to the extent that there is no problem in realizing an airtight structure. An elastic material must be set in advance.

In the case of the upper and lower rail frames to be combined with the upper and lower fixing frames, if necessary, the space between the upper mounting groove of the fixing frame and the upper rail frame and / or the lower assembly of the fixing frame may be used. Of course, it is also possible to adopt a structure in which a resilient material portion is interposed between the attachment groove and the lower rail frame portion, and in some cases, the upper and lower fixed frame portion and the upper and lower rail frame portion are It is also possible to omit any one of them and attach only one of them to the upper and lower opening frames, and to incorporate only the conventional rain closing structure between both. is there.

Further, in the embodiments described later, the mounting grooves of one fixed frame portion are independently combined with the left and right rail frame portions corresponding to the pair of upper and lower window fittings, respectively, and these fixed frame portions are combined. We adopt a structure that attaches to the left and right opening frames separately, but it is not always necessary to adopt this structure, and it is possible to separately receive the left and right rail frame parts in one continuous cross section. If the mounting grooves are formed in a fixed frame part with a structure that is provided in parallel, and one fixed frame part is attached to each of the left and right opening frame bodies, two parallel rows of mounting It is also possible for the grooves to be formed automatically.

[0016] In addition, the rising wall of the rail frame inside and outside, especially the outside of the rail, is formed into a structure in which a rain break-in structure is appropriately incorporated, and has a structure which has been adopted before to prevent rainwater from entering. In addition, the front and rear abutment between the rail frame portion and the side edge of the window fitting should prevent rattling of the window fitting in the front-rear direction (direction toward the inside and outside of the room), and besides sliding. It is extremely convenient to provide a cushioning member for preventing abrasion during movement, and furthermore, the moving range of the rail frame toward the opening frame center is fixed. As required, a hooking portion made up of irregularities for preventing the rail frame portion from being detached or a claw member is provided on the opening edge of the mounting groove of the fixed frame portion so as to be restricted to a range that does not separate from the mounting groove of the frame portion. It is also possible.

The resilient material portion is provided between the fixed frame portion and the rail frame portion to exert a function of exerting resilience. The resilient material portion has such a size that does not hinder the sliding movement of the window fitting. The rail frame must have elasticity that can follow the deformation and tilting movement of the edge of the window fitting, while being able to exert an elastic force. Either the fixed frame side or the rail frame side, Or, it can be fixed to both, or it can be combined as a simple sandwich without fixing between the fixed frame portion and the rail frame portion. It can also be provided as one of the upper and lower parts of the frame main body corresponding to the gate and the sill, or as both interposed on both the upper and lower sides, and they can be provided along the mounting groove of the fixed frame part and the rail frame part. Strips or multiple strips May be those with, for example a coil spring, a leaf spring, such as pipes, obtained by forming a metal or synthetic resin or the like into a shape that exhibits an elastic force, or natural rubber,
Materials such as synthetic rubber, urethane foam, sponge, etc., whose material itself exerts resilience, materials that use the repulsive force of magnets, or fluids such as air or liquid in a resilient elongated bag Of course, it is also possible to adopt a material enclosing the same.

The window fitting moves up and down while fitted inside the window frame main body, and opens and closes the opening of the building to prevent the invasion of wind and rain, and to perform the function of positively taking in and out air. The left and right edge sides are slidably loosely fitted and mounted in the corresponding left and right rail frame portion fitting grooves,
It is formed in a pair of inner and outer by the outer thing located on the upper side when closed and the inner thing located on the lower side when closed. Usually, when one is opened, the other is opened in conjunction with this and the other is closed Then, it is desirable that the other is configured to be closed.However, in some cases, the upper and lower are independently moved up and down, or only one of the upper and lower is vertically moved, and the other is fixed. It is also possible to make it remain.

Regardless of the vertical movement structure, when closed, the lower edge of the outer object located on the upper side and the upper edge of the inner object located on the lower side are overlapped in front and rear. In addition, if necessary, the structure of the window frame itself at the overlapping portion is meshed with each other, or it is configured to be fitted, or meshed with another member such as a sealing material, fitted, or It is configured to be in a contact state, and configured to be able to more reliably prevent infiltration of wind, rain, dust and the like. In addition, the material that forms the opening frame, fixed frame, rail frame, window fittings, etc., which are the main parts of the window frame sash for sliding doors, is the structure and architectural design of the building to be adopted, or is manufactured and assembled. Taking into account various conditions such as workability and durability, wood, metal, synthetic resin, and the like, which are usually used for building materials, can be formed alone or in an appropriate combination.

On the other hand, a fixed frame portion having an assembling groove is attached to each of the peripheral surfaces of the opening frame inside the opening frame in such a state that the opening direction of the groove is directed toward the center of the opening frame. The mounting grooves of these fixed frame portions are formed in the window frame main body by incorporating rail frame portions formed with fitting grooves having a width capable of receiving the edge side of the window fitting which must be respectively accommodated. Among the window fittings having the above structure, the outdoor upper window fitting is provided in the outer fitting groove of the left and right rail frame portions and the fitting groove of the upper rail frame portion of the window frame body, and The lower window fitting is adapted to be fitted into the inner fitting grooves of the left and right rail frame portions of the window frame body and the fitting grooves of the lower rail frame portion, respectively, and at least one of the left and right sides of the window frame body. The built-in structure of the rail frame part to the fixed frame part makes the elastic material between the fixed frame part and the rail frame part. The rail frame part incorporated in the mounting groove of the fixed frame part is regulated by a resilient force of the resilient material part so as to be constantly biased toward the center of the open frame body. It is a sliding window that has the gist of what has been done.

The above sliding window included in the present invention is expressed as follows in another expression. A suspending portion including a pulley, a horizontal axis, and the like is incorporated at a position above the window frame body that receives the upper edge of the outdoor upper window fitting, and one or a plurality of towing cords of a predetermined length are passed through the suspending portion. With one end attached to the upper edge of the outdoor upper window fitting and the other end attached to the upper edge of the indoor lower window fitting, the outdoor upper window fitting is positioned at the uppermost position. In such a state, the indoor lower window fitting is located at the lowest position, and in that state, the outdoor upper window fitting lower edge frame and the indoor lower window fitting upper edge frame are overlapped inside and outside, so that the outdoor upper window fitting and Combining with the indoor side lower window fittings, while making the window fittings, on each of the opening frame inner peripheral surface of the building opening, a fixed frame portion having an assembly groove,
Attachment is performed with the opening direction of the groove facing the center direction of the opening frame body, and the mounting groove of the fixed frame portion can receive the edge side of the window fitting which must correspond to each. A window frame main body is formed by incorporating a rail frame portion having a width fitting groove formed therein, and in the window fitting having the above-described structure, the outdoor upper window fitting is a left and right rail of the window frame body. In the outer fitting groove of the frame portion and the fitting groove of the upper rail frame portion, and the indoor lower window fitting, the inner fitting groove of the left and right rail frame portions of the window frame body and the fitting groove of the lower rail frame portion. And the mounting structure of the rail frame portion to at least one of the left and right fixed frame portions in the window frame body is such that a resilient material portion is provided between the fixed frame portion and the rail frame portion. And the rail assembled into the mounting groove of the fixed frame portion by the elastic force of the elastic material portion The window frame body and the window are formed by restricting the portion to a structure that is constantly biased toward the center of the open frame body, and the groove bottom surface of the rail frame portion fitting groove can be pressed and abutted against the edge surface of the window fitting. It can be said that it is a vertical sliding window configured so as to be airtight between the fitting edge.

The hanging portion supports one or a plurality of towing cords, which can be moved up and down in conjunction with a pair of window fittings, which will be described later, in the middle and at the folded portion. It is a function that enables the device to move back and forth on either side of the folded portion while being supported, and is located above the window frame main body that receives the upper end edge side of the upper window fitting on the outdoor side, and an embodiment described below. As shown in FIG. 2, two connecting members for separately connecting the left and right ends in the width direction of the upper edge of the outdoor upper window fitting and the left and right ends in the width direction of the upper edge of the indoor lower window fitting are separately provided. Or, while suspending a plurality of towing strings, each towing string is arranged along the left and right rail frame parts of the window frame body, and stops at the position hidden from view as much as possible,
