Description

  The present invention relates to a sliding door including a sliding gate that is installed to open and close a doorway formed at one or a plurality of locations such as a fence, a fence or a wall installed around a building, for example. More specifically, the present invention relates to a sliding door including a base frame having an annular outer frame portion having a rotatable traveling body on the lower surface, and a sliding door body raised upward from the base frame.

Since the sliding door is manufactured according to the size of the doorway, every time the doorway size is different, the base frame and the sliding door body of predetermined left and right dimensions and the front and rear dimensions are made of a metal material at a factory or the like. The base frame and the sliding door main body thus created are integrated by welding, and then a wheel as a traveling body is attached to the lower surface of the base frame to constitute a sliding door (see, for example, Patent Document 1).
Then, after the configured sliding doors are loaded onto a truck and transported to the installation location, the sliding door is lowered from the truck and then installed at the installation location.
Japanese Utility Model Publication No. 7-40997 (see FIGS. 1 and 2)

As described above, the base frame and the sliding door body are made using a metal material according to the size of the entrance and exit, and the production work of integrating the created base frame and the sliding door body by welding is troublesome work. It was. In addition, the sliding doors are often relatively large in size because they are often installed at doorways of companies and factories. Therefore, the weight of the sliding door also becomes heavy, and in some cases, the loading and unloading of the sliding door to the truck and the movement to the installation site must be performed using a heavy machine such as a crane, and the transportation work and the installation work are troublesome. Met.
Further, when a part of the sliding door is damaged, the entire sliding door must be replaced with a new one, which may be disadvantageous in replacement work and replacement cost, and there is room for improvement.

  In view of the above-mentioned situation, the present invention intends to solve the problem that not only can the production work, the transport work, and the installation work be performed easily and quickly, but also in the replacement work and the replacement cost even when partly damaged. The point is to provide sliding doors.

In order to solve the above-described problem, the sliding door of the present invention includes a base frame having an annular outer frame portion having a rotatable traveling body on the lower surface, and a sliding door body raised upward from the base frame. a was the sliding door, said running body mounted freely constituted by a screw member to said base frame, and said sliding door body and the base frame and connected freely configured by a screw member, said base frame, the right and left end by configuring in the intermediate frame part which is detachably connected between the left and right inward end of the end frame portion Toko these end frame portion positioned, the right and left inward end of the end frame portion during, made to be able to connect the plurality of intermediate frame portion coupled to the left-right direction, further the sliding door body, at least two of said end frame portion and the middle frame portion It is characterized in that it comprises a end frame portion vertical frame freely connected to each.
As described above, the end frame portion and the intermediate frame portion constituting the traveling body, the base frame, and the vertical frame portion constituting the sliding door main body are respectively produced, and the produced many constituent members can be attached to each other by a screw body. Therefore, it is necessary to transport a plurality of members assembled from some of those components to the installation location, or to transport all components without assembling all the components at the installation location. Since the assembly work can be performed, the work can be easily and quickly performed as compared with a case where the heavy sliding door that has been assembled is transported or installed using a heavy machine such as a crane. Further, when a part of the sliding door is damaged, it is possible to replace only the damaged component. In addition, the dimensions of the entire sliding door can be changed by simply changing the dimensions of some of the components. Compared to the case where the base frame is made according to the size of the doorway, the components are manufactured and transported. In addition, handling during installation can be performed easily and quickly, and the production work is advantageous. In addition, since a plurality of intermediate frame portions connected in the left-right direction can be connected, the size of the sliding door in the left-right direction can be greatly changed by changing the number of intermediate frame portions connected. The size can be easily changed and the sliding door can be manufactured more advantageously.
