[Industrial applications]

 The present invention relates to a lower end pressing device for a slide door in, for example, a refrigerator, a freezer, a storage, a cold storage, etc. (hereinafter referred to as a refrigerator, etc.).

[0002]

[Prior Art]

 Generally, in the case of a refrigerator or a freezer, floor heat insulation must be applied, and when installing a so-called three-sided frame consisting of the left and right side frames and the upper frame of the storage case and a slide door, the floor concrete is still cast. Not not. In addition, the lower part of the three-sided frame must be constructed before pouring concrete to give strength and to improve the appearance.

On the other hand, the slide door is pressed against the front surface of the side edge of the storage opening through a gasket so that the cold air in the storage compartment does not leak when the storage opening is closed. However, due to the reaction force based on the elastic force of the gasket, In order to prevent the slide door from being pushed back and separated from the edge of the storage side, it is necessary to strongly press the lower end of the slide door against the refrigerator or freezer. Various types of devices for pressing the lower end of the slide door have been proposed in the past.For example, a roller for pressing the lower end of the slide door is installed separately from the mounting of the slide door. It was attached to the concrete floor underneath via fixing brackets.

[0004]

[Problems to be solved by the device]

 However, conventionally, when constructing a refrigerator or a freezer, the construction manager determines the position of the floor surface (FL) based on the marked reference point and attaches the frame. However, the concrete finishers refer to different reference points, and the concrete placement itself has an error of about ± 20mm, so the floor finish often does not match the mounting position of the three-sided frame. .. If the floor is finished lower than the set position, the door must be attached via the spacer. Conversely, if the floor is finished higher, the door may not be able to be attached.

Further, in the door installation work, the roller for pressing down the lower end of the slide door cannot be installed unless the concrete floor surface under the storage opening is finished, and therefore before the concrete is placed. I had to go to the construction site twice later, which was very troublesome.

The object of the present invention is to solve the above-mentioned problems of the prior art, and also to mount the three-way frame and the slide door, and also to mount the roller for pressing down the lower end of the slide door before placing concrete on the floor surface. It can be completed including all, and the floor concrete can be surely placed according to the floor level when the three-sided frame is attached. Therefore, the workability is very good and the construction cost is low. There is an attempt to provide a device for pressing down the lower end of the sliding door in the above.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is directed to the front side of the left and right side frames on the lower end side of the refrigerator, etc., in which the left and right side frames and the upper frame are attached to the opening to be closed by the slide door. , Roller holding members are attached, and rollers for pressing the lower end of the slide door are attached to both roller holding members so as to project upward, and between these rollers and the front surfaces of the left and right side frames near the lower ends, There is a gap to fit the lower end of the sliding door when the storage door is closed, and the anchor to be embedded in the concrete that is placed on the floor surface under the storage door is projected downward on the roller holding member. The gist is the device that holds down the lower end of the sliding door in refrigerators and the like.

[0008]

[Action]

 According to the lower end pressing device of the slide door, the roller holding member is attached to the front side of each of the left and right side frames of the so-called three-sided frame, which is composed of the left and right side frames and the upper frame, respectively, and the slide door is attached to the roller holding member. A lower end pressing roller and an anchor are attached. Therefore, when mounting the three-way frame and the slide door before placing concrete on the floor surface, the slide door can be securely mounted by adjusting the mounting height of the roller holding member, and the bottom end of the slide door can be mounted. The installation position of the roller for pressing down the part is also determined with certainty, and the installation of the three-way frame and the sliding door can be completed before placing the floor concrete, including the installation of the roller. Moreover, in order to place the floor concrete, the lower surface of the roller holding member should be the floor level and the concrete should be placed in accordance with this level. Therefore, the work of placing the floor concrete can be done with very high workability. It can be done reliably and reliably. Also, since the roller holding member is attached with an anchor, the anchor will reinforce the roller holding member and the roller attached to this after the concrete is poured into the floor. The cost of construction is low because it is not necessary to go to the construction site twice before and after placing the concrete to install the rollers.
