Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adiabatic door device in which an adiabatic door is housed in a door frame and is openably and closably supported.

[0002]

2. Description of the Related Art In a heat-insulating door device in which a heat-insulating door is housed in a door frame fixed to a building frame and is supported so as to be openable and closable, in order to improve heat insulation, at least the upper frame and the left and right frames of the door frame are provided. There is a vertical frame in which a resin frame is connected to the indoor side of a metal frame that accommodates a heat insulating door and supports it so that it can be opened and closed (for example, Japanese Patent Laid-Open No. 9-217560).

However, in the conventional heat insulating door device,
The resin frame is formed as a single unit, and the vertical frame of the resin frame is attached so as to project from the facing surface of the vertical frame of the metal frame toward the opening center of the door frame body. A packing is attached that fits tightly to the interior side of the perimeter of the closed insulation door.

[0004]

By the way, the heat-insulating door device has a structure in which a heat-insulating door (hereinafter, simply referred to as a door) is openably and closably supported by a door frame having only a door storage portion, and a door. There is a structure that has a transom section in addition to a door storage section that supports opening and closing. And, the vertical frame of the resin frame of the door storage part needs to constitute a part that supports the closed door through packing, and the vertical frame of the resin frame of the inter-column part is a glass plate or other inter-column space in the inter-column part. It is necessary to construct the indoor side part of the structure where the panel is fitted and fixed in the dead state. When using a vertical frame of a resin frame having a single type of cross-sectional shape that satisfies the above-mentioned requirements, as in the above-mentioned prior art, in the case of a heat insulating door device with a space between the vertical frames of the resin frame of the door frame body. Although it has the advantage that it can be continued from the upper end to the lower end of the vertical frame, it has the following problems. First, the portion corresponding to the door storage portion of the vertical frame of the resin frame may be damaged or permanently deformed by hitting the load when loading and unloading the load by opening the door,
Conventionally, in such a case, it is necessary to replace the entire resin frame with a new resin frame, resulting in high repair costs. Secondly, the resin frame is integrally molded, and in order to ensure airtightness when the door is closed, the resin frame should be opened more than the facing surface of the vertical frame of the metal frame so that it closely adheres to the indoor side surface of the closed door. It is projected to the center side. Therefore, in the door device with railing, when attaching without eye, the end portions in the longitudinal direction of the eyelet are allowed to escape from the portion of the resin frame projecting toward the opening center side from the facing surface of the vertical frame of the metal frame. Since the cutting process is required, the construction cost is high, and further, since the seamless mounting direction is limited, the construction is not easy.

The vertical frame of the resin frame is composed of two types of vertical frames in which the cross-sectional shape of the portion abutting on the door and the cross-sectional shape of the portion supporting the inter-panel are different, that is, the vertical frame corresponding to the door storage portion and the inter-column portion. When separately molding the vertical frame corresponding to
If the vertical frame of the resin frame is vertically separated at the position where the unsealed longitudinal end made of metal is connected to the vertical frame of the metal frame, the heat insulation may be impaired. In order to do so, it is necessary to accurately cut the abutting end portions of the upper and lower vertical frames of the resin frame along a complicated line, and therefore the productivity is not good.

The present invention has been made to solve the above problems, and its object is to connect at least the upper frame and the left and right vertical frames of the door frame body with the resin frame on the indoor side of the metal frame. In a heat-insulating door device configured as described above, it is possible to commonly use some constituent members of the resin frame regardless of whether there is a column space or with a column space, and other configurations that differ depending on whether there is a column space or a column space. By using the member, it is possible to reduce the construction cost and the repair cost by eliminating the cutting process.

[0007]

In order to solve the above-mentioned problems, the invention of claim 1 is such that the door frame body is constructed by connecting a resin frame to the indoor side of the metal frame, and the heat insulating door is housed in the metal frame. In the heat-insulating door device that is supported so as to be openable and closable, the vertical frame of the resin frame is fixed to the indoor side portion of the vertical frame of the metal frame, and the center of the opening of the door frame body from the outer frame. It is characterized by being divided into an inner frame protruding in the direction. With the above configuration, the outer frame is provided with a structure that can be commonly used for the door frame without rails and the door frame with rails, and the inner frame has no rails without the rails and door frames with rails. In the case of a door frame, the resin frame is configured by connecting the outer frame and the inner frame for the door frame without rails, and in the case of the door frame with railing, the resin frame is connected with the inner frame for the door frame with rails. Can be configured. If the inner frame of the door compartment is damaged, it can be replaced with a new one.

In the invention of claim 1, it is desirable that the facing surface of the vertical frame of the metal frame and the facing surface of the outer frame of the vertical frame of the resin frame are flush with each other. Accordingly, in the case of a door device with a railing, even when using a seamless eye whose indoor side end portion extends in the indoor direction more than the indoor side end portion of the metal frame, only the longitudinal end portion is cut off at a right angle. It can be mounted by fitting a seamless eye between the vertical frame of the metal frame and the resin frame.

It is preferable that the inner frame of the vertical frame of the resin frame is detachably coupled to the outer frame. With such a configuration, if the inner frame of the resin frame is damaged during transportation to the installation site of the door device or during loading and unloading of luggage after the installation, only the damaged inner frame. Can be removed and replaced with a new one.

According to a fourth aspect of the present invention, the inner frame of the vertical frame of the resin frame is made to project in the direction of the opening center of the door frame body more than the facing surface of the vertical frame of the metal frame, and the outer side surface of the inner frame is provided. When the heat-insulating door is closed, the packing that adheres to the indoor side of the heat-insulating door is attached, and when a person's finger is pinched between the inner frame and the closed heat-insulating door, It is characterized by being an elastic packing that partially deforms according to the shape and protects the finger. With the above configuration, when the fingers that were left between the base end of the door and the vertical frame of the door frame when the door is closed are pressed against the door, the packing partially deforms corresponding to the fingers, so It is prevented from being injured by being pinched between the frame and the vertical frame.

In the fourth aspect of the present invention, it is desirable that the outer edge portion of the inner frame of the vertical frame of the resin frame is provided with a projecting edge for supporting an elastic packing that is pressed and deformed when the heat insulating door is closed. With the above configuration, since the packing that is deformed when the door is closed is supported, excessive deformation is prevented, the close contact performance with the inner surface of the door is maintained, and watertightness and airtightness are secured.

It is desirable that the tip portion of the projecting edge be formed of a soft resin. With such a configuration, elastic deformation at the time of finger pinching is facilitated, a strong force is not applied to the finger, deterioration of the packing is reduced, and a restoring force is assisted.

A protrusion 22d is formed at the outdoor end of 22i and projects toward the center of the opening and supports the packing p4 that is deformed when the door is closed. Further, by molding the tip end of the protrusion 22d with a soft resin, the deformed packing p4 is softly supported to prevent damage to the packing and prevent excessive deformation.

The packing p4 is crushed according to the shape of the finger when a human finger is caught between the indoor side surface of the closed door and the packing so that an excessive clamping force is not applied to the finger. Moreover, when the fingers are not caught, it has a thickness and elasticity so that it can be pressed and closely contacted with the indoor side surface of the door to ensure sufficient airtightness.

The cross-sectional shape of the packing p4 is not particularly limited as long as it has the functions of ensuring the above-mentioned airtightness and preventing injuries. However, when the finger is pinched, the elastic deformation is appropriate and the finger is not pinched. In order to satisfy both conditions for ensuring the airtightness of the hollow portion, as shown in FIG. 4, a hollow contact portion 243 is formed in the cylindrical portion 242 joined to the fitting portion 241 formed of a hard resin.
