However, in the door structure of Patent Document 1, in the door assembly process, simply fitting the peripheral edge of the glass into the recess of the elastic member does not stabilize the fixing of the glass, and it is necessary to prevent the glass from falling or tilting. rice field. Therefore, when the peripheral edge of the first glass is fitted into the recess of the elastic member, it is necessary to fit the peripheral edge of the second glass into the recess of the elastic member while preventing the first glass from collapsing. , It was a cause of increased work load.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a panel mounting structure having excellent workability without complicating the structure.

In order to achieve the above object, the panel mounting structure of the present invention is a panel mounting structure for mounting a panel to a frame via a gasket, and the frame has a recessed space between a pair of side plates facing the bottom plate. The bottom plate is formed with a protrusion protruding toward the open end of the recessed space, and the gasket is formed with a groove that fits with the protrusion, and the gasket is formed on the protrusion. The panel and the gasket come into contact with each other on the side of one surface of the panel in the gap formed between the gasket and the side plate in the state where the groove is fitted, and the other of the panels. The panel is attached to the frame in a state where the panels and the surfaces of the side plates are in contact with each other on the side of the surface.

According to the present invention, the panel and the side plate are in contact with each other, and the position of the gasket side of the panel is restricted by the gasket. Therefore, the panel can be stably fixed without being particularly complicated in structure. Therefore, the work of attaching the frame to the other end side of the subsequent panel becomes easy, and the work of assembling the door or the like becomes easy.

In the state of this figure, the pull tab 2 is attached to one side of the two panels 15, and the upper stile 3, the lower stile 4, and the vertical stile 6 are attached to the remaining three sides, respectively.

In FIG. 7, the pull tab 2 forms a recessed space 32 with a pair of side plates 31 facing the bottom plate 30, and a protrusion 33 protruding toward the open end of the recessed space 32 is erected on the bottom plate 30. .. The upper stile 3, the lower stile 4 and the vertical stile 6 all have the same structure in the main part, and in FIG. 15, the upper stile 3, the lower stile 4 and the vertical stile 6 each have a gasket 25. Gasket 26, gasket 28 and gasket 27 having the same cross-sectional shape are mounted. This mounting state is the same as the gasket 25 mounted on the pull tab 2 (see the gasket 25 in FIGS. 8 and 9).

In FIG. 15, the order of attaching the upper stile 3, the lower stile 4, and the vertical stile 6 to the panel 15 is arbitrary. Hereinafter, attachment of the vertical frame 6 to the panel 15 will be described. FIG. 16 is a cross-sectional view of the vertical frame 6 shown in FIG. This figure is a cross-sectional view in a state where the gasket 27 is attached to the vertical frame 6. As described above, the main portion of the vertical stile 6 has the same structure as the pull tab 2, and in FIG. 16, the vertical stile 6 forms a recessed space 52 with a pair of side plates 51 facing the bottom plate 50. A protrusion 53 protruding toward the open end of the recessed space 52 is erected on the bottom plate 50. A flange 56 is provided on the open end side of the recessed space 52 so that the gap 55 becomes uniform at the joint with the upper stile 3 and the lower stile 4.

The cross-sectional shape of the gasket 27 is the same as that of the gasket 25, and a groove 54 that fits with the protrusion 53 is formed. In FIG. 16, the groove 54 of the gasket 27 is engaged with the protrusion 53, and the gasket 27 is mounted on the vertical frame 6. A gap 55 is formed between the gasket 27 and the side plate 51, and the panel 15 (see FIG. 17) is attached to the gap 55. The gaps 55 are formed on both sides of the gasket 27, and one panel 15 is attached to each of the gaps 55.

FIG. 24 is an enlarged view of a portion D in FIG. 23. This figure is an external perspective view showing a state immediately before attaching the upper end cap 20. The screw 24 is inserted into the hole 63 formed in the upper end cap 20 and tightened in the screw tightening groove 64 formed in the vertical frame 5. As a result, the upper end cap 20 is fixed to the vertical frame 5. Similarly, in FIG. 23, the lower end cap 21 is attached to the lower end of the vertical frame 5 by the screw 24, and the upper end cap 22 and the lower end cap 23 are attached to the upper and lower ends of the vertical frame 6 by the screw 24, respectively.

FIG. 25 is an overall perspective view showing a completed state of the door 1. The state of this figure shows the state in which the work has progressed from the state of FIG. 23, and is completed as the door 1. The door 1 shown in FIG. 25 has the same configuration as the door 1 shown in FIGS. 3 and 4.

The panel mounting structure according to the embodiment of the present invention has been described above, but according to the panel mounting structure according to the present invention, the details are as described above, in FIG. 11, the panel 15 and the side plate 31 are face-to-face with each other. Since the position of the gasket 25 side of the panel 15 is restricted by the gasket 25 in contact with the panel 15, the panel 15 can be stably fixed without being particularly complicated in structure, and the other end side of the subsequent panel 15 can be fixed. The work of attaching the vertical frame 6 etc. (frame) to the frame becomes easy. Moreover, the said embodiment is an example, and may be changed as appropriate as described below.

In the above embodiment, the example in which two panels 15 are attached to one door 1 has been described, but one door may be used. Even if there is only one panel 15, the panel 15 is stably fixed, so that the subsequent frame mounting work becomes easy. This is the same when there are two panels 15, but more specifically, since both of the two panels 15 are stably fixed, the distance between the two panels 15 becomes constant. Since the two panels 15 are not tilted and the panels 15 do not come into contact with each other, the subsequent frame mounting work becomes easy.

In the above embodiment, the panel 15 is not attached to the vertical frame 5, but the panel 15 is attached to the pull tab 2 attached to the vertical frame 5, but this is an example, and if it is attached to the frame, it is a configuration. Often, the panel 15 may be directly attached to the vertical frame 5.

In the above embodiment, in the configuration of FIG. 11, the panel 15 and the side plate 31 are in contact with each other (see FIG. 11), but this configuration does not have to be adopted for all four sides of the panel 15. If it is adopted on at least one side of the panel 15, if the panel 15 is first attached to the one side, the panel 15 is stably fixed and the subsequent work becomes easy.
