Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging base structure of a folding door in which adjacent doors are foldable.

[Conventional technology]

For example, in the case of folding doors installed in the bathroom, etc.
A sheet of door is provided, and the mating portion of the door is foldably connected by a hinge. One of the doors serves as a hanging door, and pivots are fixed to the upper and lower ends of the end opposite to the folding side, and the pivot receiver is fixed to the rail corresponding to this. It can be fitted. The hanging door is rotated at a fixed position with the pivot as a rotation axis.

The other door body serves as a moving door, and the upper and lower ends of the end portion on the side opposite to the folding side are supported by runner members that travel in the rail. The door is opened and closed by moving the moving door.

[Problems to be solved by the device]

By the way, if it is possible to change the doorway or doorway of the folding door according to the redesign of the room, the rearrangement of furniture, or the room usage situation, it is possible to further enhance the utility value and usability of the folding door. However, in the case of the conventional one as described above, for example, in the case of a structure including two doors, one of the doors is fixed at a fixed position as a hanging door, and therefore the moving door side is provided at the exit side. Or, it is limited to the usage form in which it is used as an inlet / outlet port. For this reason, when rearranging furniture, etc., it is inevitable to give preference to the usage pattern of the folding door.

Therefore, an object of the present invention is to make it possible to arbitrarily configure the hanging base with a simple operation and to obtain a free state without the hanging base arbitrarily, thereby enhancing the utility value and usability of the folding door. The purpose is to provide a hanging structure for folding doors.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a door body that is foldable between an upper rail and a lower rail, each of which has a narrowed opening, and has a substantially C-shaped cross section. The end portion on the opposite side is a structure for suspending a folding door whose upper and lower ends are supported by runner members installed so as to be capable of traveling in the upper rail and the lower rail, respectively, and at least between the runner members of the upper rail. A suspension base fixing member that is movable in the rail and that is expanded and fixed in the rail is provided between the runner members of the lower rail and the lower rail, and the upper and lower runner members on either side of the suspension base fixing member are provided. It is configured to be fixed and form a hanging base.

[Action]

According to the present invention, for example, in a folding door including two doors, the suspension base fixing members installed between the respective runner members of the upper rail and the lower rail are moved toward the runner members on the same direction side and expanded. The suspension base fixing member is fixed in the rail, so that the door body on the side closer to the suspension base fixing member is in a state in which the runner members supporting the upper and lower ends thereof are fixed and is formed as a suspension base.

Further, by releasing the fixing of the hanging base fixing member and advancing it toward the runner member of the other door body to expand and fix it, the other door body is formed as the hanging base contrary to the above.

Further, by keeping the upper and lower suspension base fixing members in an unexpanded state, the respective suspension base fixing members are always in a travelable state, and thus both door bodies are in a free state without a suspension base as moving doors.

〔Example〕

1 to 8 show an embodiment of the present invention. Between the upper rail 2 and the lower rail 4 installed above and below the frame member, doors 6 and 8 are provided so that their mating portions are connected by hinges 10 and are foldable. Upper rail 2 and lower rail 4
Have a substantially C-shaped cross section, and each opening 2a
And 4a are each narrowed by inwardly extending edges 2b, 4b.

The ends of the doors 6 and 8 on the opposite side to the folding side are supported at their upper and lower ends by runner members 12, 14, 16 and 18 movably installed on the upper rail 2 and the lower rail 4, respectively. There is. The runner members 12 and 16 installed on the upper rail 2 are composed of runner main bodies 20 and 22 that run in the rails and runner support members 24 and 26 that are fixed to the door bodies 6 and 8, respectively. In addition, the runner member installed on the lower rail 4
14 and 18 are runner main bodies 28, which run inside the rails, respectively.
30 and runner support members 32 and 34 installed on the door bodies 6 and 8, respectively.

Further, inside the upper rail 2, between the runner bodies 20 and 22 and outside thereof, a suspension base fixing member 36 capable of restricting the movement of the runner bodies 20 and 22 is installed. Similarly, in the lower rail 4, a suspension base fixing member 38 is installed between the runner bodies 28 and 30 and outside thereof.

In the runner member 12 in the upper rail 2, as shown in FIG. 2, for example, the runner body 20 can be formed in a four-wheel structure having a screw support shaft 40 below, and the runner support member 24 is formed in the door body 6. From a main body portion 44 mounted in the mounting hole 42, a screwing member 48 having a screwing hole 46 for the screw support shaft 40 of the runner main body 20, and a fixing member 50 for fixing the screwing member 48 to the main body portion 44. Can be configured. The runner member 16 has a similar structure. Each suspension base fixing member 36 is formed with a first traveling piece 54 to which the adjusting screw 52 is attached, and a screwing hole 56 for the adjusting screw 2 while being formed so as to be fittable with the first traveling piece 54. The second running piece 58 and the adjusting screw
By the turning operation of 52, a fixed state by expansion within the rail can be arbitrarily obtained. The head of the adjusting screw 52 faces the opening 2a of the upper rail 2 so that the adjusting screw 52 can be rotated.

In the runner member 14 of the lower rail 4, the third
As shown in the figure, for example, the runner body 28 has a support shaft 60
And a columnar slide member 62 having a cylindrical shape. The runner support member 32 is mounted in a mounting hole 42 formed in the door body 6 in substantially the same manner as the runner support member 24 in the upper rail 2. Body 44 and runner body 28
An insertion member 66 having an insertion hole 64 for the support shaft 60 and a fixing member 50 for fixing the insertion member 66 to the main body portion 44. The runner member 18 has the same configuration.
Each of the suspension base fixing members 38 has a length larger than that of the suspension base fixing member 36 in the rail longitudinal direction, and has the same structure as that of the suspension base fixing member 36 except that the use position thereof is reversed. In this case, the head of the adjusting screw 52 faces the opening 4 a of the lower rail 4.

Next, the structure of the suspension base fixing members 36 and 38 will be described in detail with reference to FIG.

At the lower part of the second traveling piece 58, a convex portion 68 that fits into the opening 2a of the upper rail 2 with some margin, and a mounting portion 70 on the other edge 2b.
Is formed, and a recess 72 is formed in the upper part.
Further, a screw hole 74 is formed in the central portion, and the adjusting screw 52 is screwed into the screw hole 74. On the other hand, the first traveling piece 54 is the second traveling piece 58.
It is formed in such a size that it can be accommodated in the recess 72, and the recess 76 is formed in the upper part and the insertion hole 78 is formed in the central part.
Are formed. The first traveling piece 54 is inserted into the insertion hole 78 through the small diameter portion 52a of the adjusting screw 52, and the second traveling piece 58 is inserted.
Is attached to the tip of the small diameter portion 52a, and a retaining piece 80
Are formed.

On the head of the adjusting screw 52 facing the opening 2a, an operation groove that can be rotated by, for example, a driver is formed. When the adjusting screw 52 is screwed in, the first traveling piece 54 and the second traveling piece 58 are moved in accordance with the movement amount of the adjusting screw 52, as shown in FIG.
The space between and opens and expands, resulting in a close contact state in the rail. By this, the suspension base fixing member 36 is fixed at any position in the rail. The suspension base fixing members 36, 38 are formed in such a size that they can move in the rail in a non-expanded state. In addition, the fixed state of the suspension base fixing member 36 is released by rotating the adjusting screw 52 in the opposite direction.

Then, for example, as shown in FIG. 5, the suspension base fixing members 36, 38 installed in the middle portion are moved to move the runner bodies 22, 30 of the door body 8 to the pair of suspension base fixing members 36, 36, 38, respectively. , 3
By sandwiching it with 8 and expanding and fixing each suspension fixing member 36, 38 in this state, the upper and lower runner main body 2
2,30 are fixed in place. Therefore, in this case, the door body 8 is formed as a hanging door, and the door body 6 as a moving door can be moved to open and close the door. Since the slide member 62 has a cylindrical shape, smooth running in the rail can be obtained when the door body 6 is folded.

With such a hanging base structure, it is possible to form a folding door having a favorable opening / closing operation. That is, as shown in FIG. 6, by first fixing the runner body 22 above the door body 8 and then fixing the runner body 30 below, the pivot axis T can be easily made vertical. . In addition, even if the lengths of the runner bodies 22 and 30 are different, the lower suspension element fixing members 38 and 38
By finely adjusting, the dimensional difference d can be corrected, and the runner body 30 can be accurately positioned. Further, since the time-dependent distortion of the rotary shaft core can be easily corrected, it is possible to obtain a satisfactory opening / closing operation without a stain for a long period of time.

Further, from the state shown in FIG. 5, by loosening the suspension base fixing members 36 and 38 in the middle part and moving them to the opposite side, and fixing the runner bodies 20 and 28 of the door body 6 in the same manner, the door body 6 is fixed. It can be formed as a hanging door, and the usage pattern of the door can be easily changed. Further, if the suspension base fixing members 36 and 38 in the middle portion are always in the non-expanded state, any of the door bodies 6 and 8 can be used as an entrance or an exit. Of course, it is also possible to fix the suspension base fixing members 36 and 38 in the middle part at a specific position to regulate the opening degree on the moving door side.

In the above example, the hanging element fixing members 36 and 38 are installed outside the runner bodies 20, 22, 28 and 30, respectively, but when the door body is a folding door with a two-piece structure, These fixing functions can be covered by the frame member, and in this case, the same function can be obtained only by installing the suspension base fixing members 36 and 38 in the middle portion.

Next, FIGS. 7 and 8 show the runner support member 2 respectively.
The structures of 4,26 and 32,34 are shown in detail.

As shown in FIG. 7, an insertion hole 82 for the fixing member 50 is formed in the center of the main body portion 44 of the upper runner supporting members 24, 26, and a nut member 84 corresponding to the fixing member 50 is formed on the rear side. Is installed. Further, the screwing member 48 is formed with an insertion hole 86 for the fixing member 50. In this example, the main body 44 is made of synthetic resin, and the screwing member 48 and the fixing member are used.
The 50 and the nut member 84 are made of metal, and their efficiency is improved in terms of weight reduction and strength.

Further, as shown in FIG. 8, the lower runner support member is also formed in the same manner, and the support shaft 60 is fixed to the slide member 62 by means such as screwing.

[Effect of device]

According to this invention, the suspension base fixing member can be fixed at any position in the rail and can be released as needed, so that the usage forms of the suspension base door and the moving door can be arbitrarily changed, and It is possible to obtain a free state without a hanging source. Therefore, the utility value and usability of the folding door can be improved.

In addition, since it is possible to make fine adjustments to the axial center position of the suspension source,
Good open / close operation without squeaking can be obtained for a long period of time.
