[Embodiment] The present invention will be further explained below with reference to the drawings showing the embodiment. In FIGS. 1 to 3, A is a door frame, and this door frame A includes an upper frame 1 and left and right vertical frames 2. It is assumed that it is fixed in the form of a frame and installed in a predetermined opening according to the usual method, and at this time, the bottom end is left open and the floor surface C is finished so that it is flush with other parts.

[0010] At the lower ends of the left and right vertical frames 2 of this door frame A, a pair of joiners 2 facing each other are protruded in the inward direction of the frame surface.
0 is set. Each of the joiners 20 in this example uses a solid piece member made of synthetic resin, and in the above installation, the joiner 20 is connected to the vertical frame 2 through the through hole 21 to the opposite surface of the doorstop protrusion 3 of the vertical frame 2. It is supposed to be fixed by screws screwed into 2.

On the other hand, reference numeral 10 denotes a lower sealing frame, and this sealing frame 10 has front and rear sections comprising an upright strip 11 with an inverted U-shaped cross section that projects upward, and overhanging fins attached to the upright strip 11. It is made of an aluminum alloy extrusion and has a base strip 13.

[0012] On the back side of the above-mentioned upright strip 11, this upright strip 1
A series of downwardly opening grooves in the longitudinal direction are formed by making the cross section of 1 into the above-mentioned U-shape, and the shape and dimensions of these opening grooves correspond to those of the joiner 20. A groove-shaped engaging portion 20 is formed at the end of each joiner 20 to fit and engage with each joiner 20.

The lower sealing frame 10 is placed on the floor C in a depressed manner so that the pair of joiners 20 are received and fitted into the groove-like engaging portions 30, that is, the upright strip 11 is moved back and forth. The engaging portion 30 is attached to the joiner 20 to prevent
By engaging the left and right vertical frames 2, the floor surface is divided between the lower ends of the left and right vertical frames 2 into front and rear sections. At this time, the relationship with the door B supported in a cantilevered manner on the door frame A is as shown in FIG. be done.

On the other hand, contrary to the above, if the lower sealing frame 10 is lifted upward so that the pair of joiners 20 can escape and remain, it can be easily removed from between the left and right vertical frames 2, and this removal By doing this, the floor surface C can be made flush with the rest, except for the part of the joiner 20 on the side of the vertical frame 2, and there can be no obstruction to access, cleaning, etc.

In the figure, 12 is an airtight material provided so as to be flush with the upper material 1 of the door frame A, the airtight material of the doorstop protrusion 3 of the vertical frame 2, and 14 is the lower surface of the base strip 13 on the front and rear sides. The same airtight material installed is shown.

FIG. 4 shows another example. In this example, the joiner 20 has a fin-shaped upright piece 22 at the center of the horizontal base 23 and downward leg pieces 2 at the front and rear ends of the base 23.
4, cut into small pieces of aluminum alloy extrusion material, and embedded in the floor surface C near the left and right vertical frames so that the horizontal base 23 is flush with the floor surface. , On the other hand, this joiner 2 is installed at the end of the lower sealing frame 10.
An engaging member 31 is formed and provided with a piece-like member made of synthetic resin having a receiving groove 32 into which the member 0 is similarly received and fitted. In addition, in this example, a lower frame 4 for embedding in the floor C made of extruded aluminum alloy material on which the lower sealing frame 10 is placed is additionally used, but the rest is different from the previous example. Since there is no such thing, the same reference numerals are given and the explanation thereof will be omitted.

FIG. 5 further shows the joiner 2 of FIGS. 1 to 3.
0 is shown in an example in which it can be stored in the vertical frame 2 when the lower sealing frame 10 is removed. In this example, although not shown, a notch of a predetermined length is provided on the opposing surface of the lower end of the door stop ridge 3 of the vertical frame 2, and a guide hole 25 is provided transparently at one end of the joiner 20. However, a support shaft 26 passing through the guide hole 25 is provided on the front and rear sides of the door stop ridge 3, so that the joiner 20 can be freely rotated. Since the rest remains unchanged, the explanation thereof will be omitted.

Furthermore, FIG. 6 shows an example in which the joiner 20 is provided in the lower sealing frame 10. In this example, the upright strip 11 of the lower sealing frame 10 is formed in a hollow shape, and the hollow portion 15 The joiner 20 can be housed in a protruding and retractable manner, and when the joiner 20 is arranged in an erected manner, the joiner 20 is made to protrude and a groove-shaped engagement member provided on the floor side is used. 31. In the figure, 16 indicates a slide hole provided in the upright strip 11 on the side not facing door B, and 27 indicates a handle for protruding and retracting the joiner 20.The rest is unchanged, so the same reference numerals will be given and explanations will be given. Omitted.

[0019] The illustrated example is as described above, but the upright strips may be fin-shaped erected on the base, and a downward engaging portion may be provided on the base, or a predetermined engaging member may be attached to the base. You can also do this. In this case, by providing an engaging portion below the fin-like upright strip, if the rising width becomes large, the engaging portion or engaging member may be provided in a rearward overlapping manner in the upright shape.

[0020] On the other hand, due to its location, the upright strip may face the lower end of the door body but be separated from it, and in such cases when airtightness is required, the lower end of the door body may be separated. It is also possible to bend and extend this upright strip to a fixed position and install an airtight material at its tip.

[0021] The joiner and the engaging portion or the engaging member may be engaged in a manner that prevents movement in the front and back direction. In order to make the condition more reliable, metal fittings such as pins and clips may be additionally used, and joiners and engaging members may be attached to the floor at or near the bottom of the vertical frame.
If a separate lower frame is used as in the above example, it should be fixedly installed at the frame position of the frame, or on the upright strip or its base strip, or it should be retractably stored as in the above example. Either is possible, and it may also be possible to remove it each time and fix it as necessary.

Furthermore, when there is a hanging side of the door body, such as a door frame, for example, the joiner on the vertical frame side can be rotatably locked to the door body side, and the door body can be opened like a door stopper. It is also possible to use it as a holding means.

Furthermore, in the upright strip in the above example, it is possible to omit one or all of the airtight materials, to use other types of airtight materials, to add water return as necessary, and to attach the lower frame. If a frame is used, it is possible to provide a pair of low rigs for positioning, provide anti-slip means, and also allow the door body to be opened, and other objects that can be raised and lowered (for example, vertical panel shutters, etc.) to be used. ), and in this way, in implementing the present invention, each specific structure, shape, material, and size of the upright strip, joiner, engaging portion or engaging member, and door body may be modified. , usage, installation location, etc. can be changed in various ways as long as they do not go against the gist of the invention, and there is no need to limit them to what has been illustrated and described above.

[0024]

[Effect of the invention] Since the present invention is configured as described above,
It provides removability that allows the upright strip to be easily removed or installed. Therefore, for example, airtightness, watertightness, soundproofing,
If you want to obtain or improve any of the light leakage blocking properties, you can install uprights to block the door, and on the other hand, if you open and close the door frequently or leave it open, This can be removed when moving in and out of the trolley or for cleaning, allowing you to obtain a flush or nearly flush floor surface or a flat lower edge of the window. Problems seen in the frame can be resolved.
