Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window support, and more particularly to a window support that is convenient for forming a single-layer window into a multi-layer window by providing a second window panel.

It is well known that multi-paned windows are more effective than single-paned windows for heat dissipation and prevention of heat intrusion, and multi-paned windows are increasingly being used for windows in cold regions and frozen window windows. . Since such multi-layer windows are expensive to manufacture, various attempts have been made to replace them with a multi-layer window by simply providing a second window panel on a conventional single-layer window. For example, JP-A No. 53-126737 and JP-A No. 53-130835 state that "the first glass 3 has a U-shaped cross section with a groove that holds the edge 3a of the first glass 3, and groove edge 2 of window frame 2
A U-shaped body Q having jaw grooves 10a and 10b that engage with the U-shaped grooves 10a and 2b, respectively, and a support R that is located at one edge 11 of this U-shaped body and that locks the presser member 7 are made of metal or hard material. "A device that is integrally made of a hard material such as a synthetic resin, and in which a holding member that holds the second glass is supported by both window frame groove edges 2a, 2b" and "A conventional single-layer window that is adhered to A member for joining a plurality of parts and a clamping piece (indenter) for clamping the secondary plate are formed on the clamping plate that clamps and holds the fixing plate to be fixed and the sub-plate, respectively, and at least one member, for example, one of the fixing plates, is formed. A device in which the part is filled with a desiccant agent is disclosed. As is clear from the drawings included in the same publication, it has a very sophisticated structure, but it takes time and effort to construct, and its durability is limited due to the large number of parts and engaging parts. The disadvantages cannot be avoided. The inventor of the present invention has conducted extensive research into the structure of a window support that avoids the drawbacks of conventional complicated structures and achieves similar effects with a simple structure, and has arrived at the present invention. That is, the present invention provides a double-layer window support consisting of an elongated support A and a pair of holding members B, in which the elongated support A
In this case, part b that sets the interval between the first window plate and the second window plate is placed in the center, and a convex part a having an L-shaped cross section is provided on one side of the part b for fixing the first window plate. and on the other side, a protrusion having an L-shaped cross section for positioning and sealing the second window plate, and having a ripple formed on the surface in contact with the window plate bent toward the outside air side for sealing. c and a recessed part T formed on the window frame side, with the bottom side of the protruding part c as one side, and the holding body B
This is a multi-layer window support body characterized in that the second window plate is fixed by the protruding part c by fitting the second window plate into the recessed part c.

The elongated support and clamping body of the present invention do not necessarily have to be integral over the entire periphery of the window panel. The L-shaped cross-sectional protrusion a is for sandwiching the window plate between the elongated support body and the protrusion, and does not necessarily have to be strictly L-shaped. It may have a recess for fitting into the window frame and a suitable protrusion for elastically supporting the window plate.
It may also have edges for better attachment to the window frame. Various aspects of such modifications will be easily understood by way of illustration in the accompanying drawings.

Further, the part b is for setting the distance between the first window plate and the second window plate, and preferably the top part of the elongated support body is used as it is. Examples of window panels include organic or inorganic plate-like materials, which may be transparent or opaque.
Furthermore, a film or the like having a function such as heat ray reflecting ability may be attached.

The protruding portion c is provided on the opposite side of the L-shaped protruding portion a with respect to the elongated support body and the portion b. The protruding part c has a generally L-shaped cross section in order to position and seal the second window plate, and has a configuration in which a ripple is formed on the surface that contacts the window plate by bending toward the outside air side for sealing. It is becoming. A recess with the bottom side of the protrusion c as one side is formed on the window frame side of the protrusion c, and by fitting a clamping body to be described later into this recess, the second window plate is fixed to the protrusion c. It's summery. In other words, it has a structure that is easy to assemble and can be sealed from outside air. The holding body has a convex portion that fits into the concave portion on the window frame side of the protruding portion c to stabilize the fixation of the second window plate, and is usually the same size as the elongated support body. Although it is a long body, it does not necessarily have to be so.

Further, the holding body may have a structure that cooperates with the protruding portion c to help accommodate the end portion of the second window plate.

To explain the present invention with reference to the drawings, in FIG. 1, the elongated support A is paired with the clamping body B,
The elongated support A has a protruding portion a having an L-shaped cross section for fixing the first window plate E, and furthermore, the distance between the first window plate E and the second window plate is set. It has a setting part b at its top, and also has a protruding part c for positioning and sealing the second window plate. As shown in FIGS. 1 and 2, the protrusion c has an L-shaped cross section as a whole, and is designed to accommodate the end of the second window plate, as well as to accommodate the end of the second window plate. A ripple curved toward the outside air side for sealing is formed on the contacting surface, so that when it is fixed, it can be sealed around the window plate. The holding body B has a protrusion c,
Fitting into the recess formed by the other protrusion 2,
Ensure fixation to the second window plate. The clamping body B can assist in accommodating the end of the second window frame as shown in FIG.

Further, a convex portion (a) for elastically fixing the window plate may be provided in the accommodation portion at the end of the first window plate formed by the L-shaped convex portion (a). Also, L
The letter-shaped protruding portion a may have an edge portion a for effective insertion into the window frame. Further, it may have recesses C and C' into which the end portions of the window frame are fitted.

The upper portions of FIGS. 1 and 2 show how the elongated support A and the clamping body B are fitted to firmly fix the window panels E and F.

Both the elongated support A and the clamping body B do not need to be made of the same material as a whole, and may be a combination of a hard material and a softer material as appropriate. According to the present invention, in addition to ease of manufacture and ease of attachment and detachment, dew condensation prevention properties are also achieved. That is,
Referring to FIG. 1, a ripple is formed in a portion of the protruding portion c that contacts the second window plate. Therefore, in a multi-layer window in which the clamping body B is fitted and fixed to the second window plate, when a difference in pressure occurs between the inside and outside of the multi-layer window, the ripple will not allow gas to flow from the inside to the outside. Prevent gas from flowing into the interior from the outside.

In other words, in the case of conventionally known simple double-paned windows, the double-paned windows breathe due to temperature changes between daytime and nighttime, which causes external humidity to be trapped within the double-paned windows, causing condensation. However, in the present invention, it is difficult for outside air to flow into the double-paned window, so
It can block most of the outside moisture and prevent condensation.

As described above, the present invention provides a support for a multi-layer window that has a simple structure and is easy to manufacture and assemble, realizing the above-mentioned excellent multi-layer window, and is very useful.
