DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking door mounting apparatus and method for preventing swinging and rattling during opening and closing operations of a sliding door provided in an opening of an assembled building or the like.

[0002]

2. Description of the Related Art Conventionally, an interlocking door as this type of interlocking door apparatus is composed of a first door provided at both ends with a door roller rolling a guide rail attached to a house or the like, and a first door provided with the first door. Like the door, second suspension doors provided at both ends with a door roller rolling the guide rail were provided, and door rollers provided at one end of the first suspension door were provided at both ends of the second suspension door. A sub-guide rail that arranges both hanging doors so as to be located between the door cars and moves the hanging door by rolling the door car of the first hanging door, facing the guide rail on the second hanging door. An interlocking type suspension door provided with a door wheel 8, 9 and a door wheel 13, as shown in FIG. 4 or 5 of Japanese Patent Publication No. 57-35349.
Comparing the diameters of the door wheels 13, 14,
Each dimension is determined to be slightly smaller than 9, which is also described in the detailed description of the invention. That is, the second suspension door (outer door) is supported by one door of the first suspension door (inner door) via the auxiliary guide rail, and the left and right doors of the second suspension door have the same diameter. Is smaller than that of the first suspension door, so that either the left or right door roller is combined in a state of being lifted off the rail (balance state).

As another prior art, there is a "locking device for an interlocking door roller" described in Japanese Patent Application Laid-Open No. Hei 8-232543 which is a prior application of the present applicant. In this case, as can be seen from the drawing, the outer door is supported in a balance-like manner such that one of the outer doors is slightly raised with one roller of the inner door positioned below the movable rail as a fulcrum.

[0004]

The reason why the relation between the movable rail and the roller in each of the interlocking doors is a balance-like structure as described above is that when one door is opened and closed, the other door is opened and closed. The door to be operated (outer door) because the movable rail (sub guide rail) and the roller located below and in contact with it must always maintain a frictional force in order to work together. By providing a small gap between the right or left side roller opposite to the upper edge of the fixed rail and the fixed rail, a continuous load at the contact point is applied to the roller at the fulcrum contacting the contact point. . However, at the time of opening and closing the door, when the roller serving as a fulcrum shifts to the left or right from the center of gravity of the outer door in the above-described state, the door tilts slightly to the right or left due to a slight gap with the fixed rail. Upset, causing rattling.

Therefore, in the present invention, the left and right rollers of the outer door are always in contact with the fixed rail without loosening the frictional force between the movable rail and the roller supporting the movable rail in contact with the lower side. It is an object of the present invention to provide an interlocking door mounting device without rattling by preventing the outer door from tilting to the left and right and swinging in a state where the outer door is tilted.

[0006]

As means for solving the above problems, a roller at the upper end of a door is loosely fitted on a fixed rail provided on an upper edge of an opening of a building so as to be freely pulled and suspended in a pulling manner. In the interlocking door configured to link and move the door with the movable rail provided at the upper end of the outer door on the roller of the inner door, when the movable rail is mounted on the roller of the inner door, the weight of the outer door is reduced. And a method of mounting the interlocking door, wherein the movable rail provided at the upper end of the outer door is elastically formed. For example, the movable rail is formed separately from the supporting portions of the rolling rollers provided on both sides of the movable rail so as to impart elasticity such that the mounting portion can easily expand and contract.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an assembled building on which an interlocking door mounting apparatus according to the present invention is constructed, showing a main part of the door mounting by breaking an upper right portion thereof. 2 is an outer door, 3 is a fixed sleeve wall, 4 is a fixed rail, 5 is an upper frame and roof receiver, 6 'is a movable rail, D is a right roller of the outer door 1, 8 is a closing plate, and 9 is a front floor frame. Sill, 1

FIG. 2 is an enlarged perspective view showing a state in which the inner door 1 and the outer door 2 are fitted to and engaged with the fixed rails 4 above the front opening of the assembled building. Rollers A and B opposite to the upper and right portions of the upper end of the inner door 1 via bearings 7 and 7 are rollably mounted and loosely fitted on the groove. A roller which is mounted on the roller B with a movable rail 6 'provided in an inwardly protruding state along the upper end edge, and which is protruded via roller support portions 6, 6 provided on both right and left ends of the movable rail. C and D are also fixed rails 4 on both sides with the roller B in between.
Rollably mounted on the groove of (1). Accordingly, by moving the outer door, the roller B rolls between the movable rail 6 'and the fixed rail 4 in contact with both rails, and the inner door 1
It interlocks with the outer door 2 at a speed and moving distance of / 2. In addition,
The movable rail 6 ′ is formed of a plate material having a thickness of 0.6 mm to 0.8 mm and having elasticity so that the movable rail 6 ′ is separated from the roller supporting portions 6 on both sides thereof and separate from each other. Rollers C and D are mounted via bearings 6a.
The roller b is formed so as not to come into contact with the roller A or B by contacting the bearing 7, so that the opening and closing operations of the inner and outer doors can be smoothly performed without any obstacle. The arrow in the figure indicates the front direction.

FIG. 3 shows the inside and outside doors 1,
2 is an enlarged vertical cross-sectional view of a right end portion, in which a lower portion is omitted, in a state in which the fixed rail 4 is suspended,
Roller and movable rail 6 '
Of the movable rail 6 ′ does not come off from the roller B, and protects the inside of the fixed rail 4 from rainwater and dust.
The appearance of the front part of the fixed rail 4 is improved, and the opening of the building is reinforced with the closing plate 8.

In FIG. 3, the rollers are arranged in a line on the fixed rail 4 in the order of D, B, C, A from the near side, and all the rollers are overlapped with D in front. The inner door 1 is provided by rollers A and B, and the outer door 2 is provided by rollers C and B.
D hangs on the fixed rail 4. A movable rail 6 ′ having an inverted L-shaped vertical section is formed between the rollers C and D of the outer door 2 so as to be separated and covered over the roller B, and the roller B is mounted on the movable rail 6 ′. It is configured to roll by couple.

FIGS. 4 and 5 are rear views of the essential parts of the door when viewed from the inside to the outside of the door so that the positional relationship between the rollers can be clearly understood. FIG. , The roller B is at a position separated from the movable rail 6 ′, and stops in a state where the roller B does not contact with the roller C. The height h from the fixed rail 4 to the movable rail 6 'is formed slightly lower than the diameter H of the roller B. The rollers A, B, C, and D have the same diameter and are arranged at the same height on the fixed rail 4.

FIG. 5 shows a state in which the door shown in FIG. 4 is being opened from the closed state, and the movable rail 6 'is placed on the roller B by moving the outer door 2 in the direction of the arrow. Outer door 2 at the contact point between B and the movable rail 6 '
In this state, the movable rail 6 'is bent by a plate material having a thickness of 0.6 mm to 0.8 mm. Since the height to the fixed rail 4 becomes H, the roller C or D at the upper edge of the outer door does not rise from the fixed rail 4 and always keeps the state in contact with the fixed rail.
Therefore, the outer door 2 moves horizontally in the vertical state without tilting even during the opening and closing operation, so that the door does not rattle and a stable frictional force is always obtained at the contact point between the movable rail and the roller B.

FIG. 6 is a view showing a state in which the door mounting portion of the conventional example is being opened and closed. In order to link the inner door 1 'by operating the outer door 2', a roller B 'and a movable rail 6 "are used. In order to obtain a stable frictional force at the contact point between the roller B 'and the roller B' as a fulcrum, either the roller C 'or D' is slightly lifted from the fixed rail 4 'so that a load is easily applied to the roller B'. In the drawing, the roller D 'is lifted by G from the fixed rail 4'.
Therefore, as the position of the roller B changes, the outer door 2 that is being opened and closed changes its inclination from right to left, or vice versa, which causes the door to rattle.

[0014]

According to the present invention, the movable rail at the upper end of the outer door mounted on the roller of the inner door elastically forms the movable rail so as to extend downward by its own weight. The left and right rollers opposite the upper edge of the outer door are always in contact with the rail without lifting from the fixed rail, so when opening and closing both doors, the outer door must be Since it does not tilt and shake, rattling is prevented, the door moves smoothly in the horizontal direction, and a light door opening / closing operation can be performed. Moreover, since the frictional force at the contact point between the movable rail and the roller contacting the lower side is always stably held by the weight of the door, the contact of the inner door can be reliably performed without the contact point slipping.
