Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a stepped lower frame of an opening member suitable for installation at a place having a step on a floor inside and outside an opening member body, for example, in a bathroom door.

[Conventional technology]

For example, as an opening member provided between the bathroom and the undressing room, for example, a center-folding type folding door body in which two panels suspended above an upper frame are flexibly connected to each other, a single-opening type having a single door body. Bathroom doors having a door body are generally used.

Since there is a step between the bathroom and the dressing room, the folding door body and the door body are to be opened and closed on the bathroom side with a low floor, and the lower frame used for this is generally in contact with the lower ends of these bodies. An abutting portion and a draining portion inclined from the abutting portion toward the bathroom side are provided so as to project from the abutting portion, and the abutting portion also serves as a water return on the undressing room side.

[Problems to be solved by the invention]

Since the lower frame has an inverted U-shaped cross section, the main frame is received and held at the contact portion, and the lower frame is not engaged with the lower frame.
When the main body is closed, flapping tends to occur, and particularly when the folding door main body is used, the flapping tends to appear remarkably on the structure.

On the other hand, there is still a step between the bathroom floor and the lower frame, but this step is reduced by the inclined drain section, and is generally a small step of about several cm.

For this reason, if you take a bath with the body of the bathroom door closed,
The bath water spreads over the drain, and sometimes permeates the dressing room side beyond the contact part, and this kind of lower frame is not always satisfactory in terms of the watertightness of the opening member.

An object of the present invention is to provide a stepped lower frame of an opening member which is used for partitioning a floor surface having a step so as to suppress flapping of the opening member main body and improve watertightness as much as possible.

[Means for solving the problem]

According to the present invention, according to the present invention, a one-side hanging strip protruding downward from a contact portion which is in contact with a lower end of an opening member main body, and a lower end and an upper end of the hanging strip are positioned in an overlapping manner and fitted between the hanging strip. A fixed outer frame provided with a stepped lower-side other rising member protruding upward to be spaced apart so as to form an insertion groove, and a lower one-side engaging member and rising rising protruding upward on the hanging member side. On the ridge side, it has a height corresponding to the rising ridge, and is protruded upwardly at a distance so as to form a holding groove between the one-side engaging ridge, and further bent downward at the tip thereof. And a movable inner frame for holding the opening member main body, which is provided with a stepped high-level other-side engaging strip, and which is fitted in the fitting groove of the fixed outer frame so as to be able to move up and down. The present invention relates to and relates to the step lower frame of the opening member.

[Action]

According to the present invention, when the opening member main body is closed, the movable inner frame is raised vertically or in one side inclining direction from the fixed outer frame to hold the opening member main body, while holding the opening member main body before opening. Is released, and is used via elevating means provided on the lower frame so as to be inserted into the insertion groove of the fixed outer frame.

Therefore, in the closed state, the opening member main body is held in a holding state by the raised movable inner frame to prevent the fluttering of the opening member main body, and when used for the bathroom door, other than the stepped height of the raised movable inner frame. The side engaging strip forms a water blocking wall.

Side, i.e., on the side of the bathroom A in this example, at the end of the horizontal board 70, the engaging strip 71 is separated from the engaging strip 71 so as to form the holding groove 73 of the door body 8 with the engaging strip 71. And project upwards,
In addition, the rising strip 67 is covered so as to cover the upper end thereof.
And a bathroom-side engaging strip 74 having a stepped height that is further bent downward at the tip of the facing strip 72 having a height corresponding to that of the movable strip 72. The reference numeral 69 is such that the relative length thereof is regulated so as to have a dimension slightly shorter than the length of the fitting groove 68 in the fixed outer frame 61, and the one-side clearance 75 is set in the fitted state.

The door body 8 has four panels 81... Arranged on the outer periphery of the panel material connected in a frame-like manner by connecting hinges 82 a, 82 b, and 82 c, and is moved to the panels 81, 81 located at the ends by moving frames 83. In the same manner, the moving frame 83, the running frame 84, and the door hinge 85 in which a pair of rolling wheels are block-connected at the upper end of the connecting hinge 82b at the center position, and a block-shaped lower end at the lower end. The guide pins 86 are arranged and fixed to project upward or downward, respectively. At the upper ends of the other two-sided connecting hinges 82a and 82c without the door roller 85, horizontal door rollers 87 are arranged and fixed so as to be close to the hinges.

The door main body 8 mounts the door roller 85 on the horizontal guides 31 and 31 of the upper frame 3 and fits the guide pins 86 into the holding grooves 73 of the movable inner frame 69 to form the door frame 2. The door body 33 can be folded and opened and closed at the door pocket portion 33 in the shape of an abdomen of the door body 8.

In the bathroom door 1 of this example, a movable inner frame in the lower frame 6
The reference numeral 69 designates a freely movable up-and-down movement in the fitting groove 68, which is lowered when the door body 8 is opened, and when the door body 8 is closed.
It is designed to rise in the stretched state.

The raising and lowering of the movable inner frame 69 is automatically performed in conjunction with the opening and closing movement of the door main body 8 via the inner frame raising and lowering means. In this example, the movable frame 83 of the door main body and Running frame
The block-shaped guide pin 86 in 84, the pressing portion 91 traversing the holding groove 73 provided at the end of the movable inner frame 69, and a door wheel fixedly provided in a protruding manner on both sides of the movable inner frame 69 as a front and rear pair. 92 and this door wheel 92 has an inclined surface that rolls in the inclined direction, the upper end is made horizontal on the vertical frame side, and each fixed outer frame
Each of the guide blocks 93 and 94 has a trapezoidal groove on the side of the bathroom B and a trapezoidal groove extending along the side of the dressing room A, which is disposed and fixed at the end of the insertion groove 68 of the cylinder 61.

In this bathroom door 1, if the folded door body 8 is extended and closed, the guide pin 86 in the traveling frame 4 becomes
The pressing portion 91 of the movable inner frame 69 on the side of the clearance 75 is pressed, and the door wheel 92 receives the pressing force, and the door wheel 92 is guided by the guide blocks 93, 94.
The movable inner frame 69 to which the door roller 92 is fixed is fixed to the undressing room A-side engaging strip 71 by the hanging strip 66 of the fixed outer frame 61, and the bathroom side The joint member 74 is inclined upward from the insertion groove 68 while being guidedly engaged with the rising member 67, and the lower end of the door body 8 is held in the holding groove 73 of the movable inner frame 69. As a result, a barrier is held in the bathroom B side in a covering state, and a barrier wall having a height substantially equal to the floor of the undressing room A against the bath water is formed. In this example, the door body 8 is closed by a stopper 51
Therefore, the door frame 8 and the vertical frame 5 are separated from each other in the closed state, and the clearance 75 is formed on the vertical frame 5 side. Will lead to.

Conversely, if the door body 8 is to be opened, the door body 8 moves to the vertical frame 4 side in the closed state, and the guide pin 86 of the moving frame 84 presses the pressing part 91 on the opposite side, and The movable inner frame 69 is returned to the fitting groove 68 by the operation opposite to the above, fitted and inserted and stored, and the door body 8 can be folded toward the bathroom B side.

Although the illustrated example is as described above, in the implementation of the present invention, the hanging strip of the fixed outer frame and the lower engaging strip of the movable inner frame,
Alternatively, the rising strip and the engaging strip having a higher step may be formed into a narrow groove by forming one or both of them into a plurality of strips so that they are engaged with each other.

Also, for example, when using the above-described lifting / lowering means, the guide block and the door roller are bent by a member extending upward so as to be accommodated in a receiving groove formed by opening the fitting outer groove side of the fixed outer frame. The upper strip may be configured to be located above the receiving groove.

On the other hand, the engaging ridge at the high step in the movable inner frame may be an upward fin-shaped projecting projecting upward away from the movable inner frame, instead of being bent and suspended as in the above example.

It is generally preferable to raise and lower the movable inner frame inserted into the fixed outer frame in conjunction with the opening and closing movement of the opening member. In this case, the raising and lowering is performed in the inclined direction as in the above example, and also in the vertical and vertical directions. It is also possible to perform it.

For raising and lowering the movable inner frame linked to the opening and closing movement,
Although the above example is simple, for example, between the fixed outer frame and the movable inner frame, a plurality of pantograph-like link devices connected by a connection shaft are interposed, and an opening member is provided with a rising piece provided on the connection shaft. The movable inner frame, which is made to operate as a push-up operation, is linked to the movable inner frame on the upper frame side, for example, in a similar manner,
The middle bent portion is pressed by the opening member and returned by a spring, the movable inner frame is suspended by wire, and the lever is pressed by the opening member and wound around the movable inner frame. Various elevating means combining mechanical elements, such as those returned by a spring between frames, can be used. When the opening member is large, it can be electrically driven.

As can be seen from the above, in practicing the present invention,

The specific shape, structure, material and dimensions of the movable inner frame, the relationship between them, and the lifting / lowering means and the type and size of the opening member that may be added to the present invention are variously implemented as long as they do not contradict the gist of the present invention. It is possible and need not be limited to those shown and described.

〔The invention's effect〕

Since the present invention is configured as described above, the lower end of the opening member is held in the holding groove of the movable inner frame in a closed state in the closed state, and therefore, when the various opening members including the folding door are closed. Prevents flapping.

In addition, since the movable inner frame is raised, the stepped higher engaging strip is disposed above the rising strip of the fixed outer frame in a continuous state with the rising strip. Even if it is installed in a violent place, a barrier against these intrusions will be formed, and the sealing performance of the opening member will be improved.

On the other hand, in the open state of the opening member, the movable inner frame is inserted into the insertion groove of the fixed outer frame so as to be able to move up and down, so that the height of the lower frame as a whole can be formed relatively low, Also, at this time, the engaging step at the high step is lower than the contact part, so that these are inclined, which makes it easy for people, cars, etc. to get in and out, and feels pain even when riding on the lower frame with bare feet. Can be prevented.
