Description

[Detailed description of the invention] This invention relates to a cover for sash that covers the mullions and non-woven surfaces of panels and window frames that make up the exterior walls of buildings, etc., and can be attached and removed from the sash parts of the mullions and non-woven parts. It is an object of the present invention to provide such a cover that is easy to use and has effects such as good heat insulation properties.

The present invention will be described below with reference to drawings showing embodiments.

Figures 2.4.5 show an example of the sash cover of the present invention implemented in a mullion, and in each figure, the upper side is the outdoor side and the lower side is the indoor side.

To explain Fig. 2 showing the first embodiment, 1 is a mullion interposed between two pieces of glass 2, 2a, which is integrally made by extrusion molding of aluminum alloy, and holds the glass through a backing. Along with this, it also serves as a strength component for the satsushi.

3 is a cover for the outdoor sash, which is made of a thin plate made of aluminum alloy, stainless steel, etc. and has a U-shaped cross section so as to wrap around mullion 1 on three sides, and the ends of both sides that correspond to both legs of the U-shaped cross section are The locking portion 4 has a V-shaped cross section toward the front.

The locking portion 4 is attached to the mullion 1 by resiliently engaging with protrusions 5 provided on both outdoor side surfaces of the mullion 1.

13 is a heat insulating material serving as a spacer.

A space 6 is formed between the cover 3 and the mullion 1 to provide a heat insulating effect.

Reference numeral 7 designates a cover for an indoor sash, and a locking portion 8, which is provided on the cover 7 and has a V-shaped cross section toward the mullion, is elastically engaged with a protrusion 10 that is provided on the mullion 1. It is attached to mullion 1.

9 is a space between the cover 7 and the mullion 1.

The sash covers 3 and 7 and the mullion 1 are
Only the tip of the shaped cross section is in contact with the mullion, and the rest of the cover has a space between it and the mullion, so it has a heat insulating effect.

Since the covers 3 and 7 are obtained by molding thin metal plates such as aluminum alloy and stainless steel, it is easy to provide elasticity that allows the locking parts 4 and 8 to be pressed against the sides of the mullion. The covers 3 and 7 are removably covered on the mullion 1 by using the following.

That is, if the cover is attached by engaging the locking portions 4.8 of the cover with the protrusions 5, 10 of the mullion 1, the cover will be securely attached only by the elasticity of the sides of the covers 3, 7.

In order to facilitate attachment of the cover 3 to the mullion, it is effective to provide the locking portion 4 near the opening of the cross-section of the cover, which has a square box shape.

Here, as shown in FIG. 3, the protrusion 5.10 is
The insulation effect can be further improved by interposing a heat insulating material 11 (such as rubber) between the locking parts 4 and 8 to prevent the covers 3 and 7 from coming into direct contact with the mullion 1.

In the embodiment shown in FIG. 4, the shapes of the covers 3 and 7 are changed to correspond to the different shapes of the mullions.

Fig. 5 shows an embodiment in which the central part of the mullion 1 is connected to a large groove 12, and a heat insulating material 13 is inserted into the space 6 near the central groove 12 to ensure more secure installation. It is something.

FIG. 6 shows an example in which the sash cover of the present invention is implemented in a closed section 14.

As configured as described above, the sash cover according to the present invention has the following advantages.

(1) Since structural strength members such as sashes and curtain walls are covered with covers, surface treatments for aesthetic purposes such as anodic oxide films and paint films are not required, which is economical.

(2) Since the cover 3 is crimped and connected to the sash etc. using elasticity, it can be attached and detached very easily, and no special attachment equipment is required.

(3) Provide a space between the satsushi and the cover, and
By interposing a heat insulating material such as rubber between the contacts and crimping them together, the insulation effect for heating and cooling inside the building is increased, contributing to energy savings.

(4) By coloring only the cover and making it removable,
It becomes possible to freely combine exterior appearance, interior color tones, patterns, etc.

(5) Although the outside of the building is susceptible to corrosion, the cover 3 prevents the mullion from being corroded, and even if the cover corrodes, it can be easily replaced.

(6) The appearance of the building can be easily changed by replacing the cover with a different color.

It has great practical effects.
