Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door guide device which guides an upper portion of a sliding door with a telescopic beam. In this case, the door weight is supported by a door roller or a similar traveling tool provided below the door panel.

[0002]

2. Description of the Related Art Sliding doors using a telescopic beam as a guide element are disclosed, for example, in JP-A-60-253683, JP-B-59-44524, and JP-A-58-143076.
It is publicly known in Japanese Patent Publication No. However, these basically consist of hanging door-type sliding doors in which all of the door weight is supported by telescopic beams.
The telescopic beam is provided with a guide rail having a C-shaped cross section that is fixed to the upper frame portion of the opening frame and opens toward the indoor side, and a slide frame that runs along the guide rail. Hanging.

Since the above-mentioned telescopic beam bears all of the weight of the door by the slide frame, the telescopic beam itself needs to have sufficient strength. Therefore, the size of the guide device is easily increased. For example, in a room where the atmosphere is important such as a living room, the appearance is too stiff and the application is hesitated. Even when the sliding door is fully open, it is necessary to guide and support the slide frame with the guide rail.In many cases, the guide rail cannot be avoided from protruding to the upper outside of the door panel when fully closed. However, it tends to spoil the indoor atmosphere.

[0004] The present applicant has previously proposed an upper guide device using a telescopic beam, which can be applied without any discomfort to a room where the atmosphere is important (Japanese Patent Application Laid-Open No. 9-209649). There, a telescopic beam is fixed by a guide frame fixed to an opening frame, an upwardly opening slide frame fixed to the upper end of a door panel, and a floating beam arranged between the two frames and capable of sliding relative to each frame. Make up. The upper and lower surfaces of the idler beam are provided with an upper roller that is rolled and guided by a guide frame, and a lower roller that is relatively rolled and guided by a slide frame. Near the both ends of the slide frame, contact the lower roller,
An abutment for operating the floating beam in the same manner is protruded from the bottom wall of the frame. Door weight is supported by a door wheel attached to the lower end of the door panel.

[0005]

The telescopic beam does not need to bear the weight of the door, and only needs to have the function of preventing the door panel from oscillating. Therefore, the whole apparatus can be downsized.
When the door panel is fully opened, the slide frame is supported by a floating beam that projects halfway from the guide frame, so that the left and right length of the guide frame can match the left and right width dimensions of the door panel, and the door panel can be closed. In the retracted state, the floating beam and the slide frame can be respectively housed in the guide frame, so that the appearance can be improved.

[0006] The problem is that the door panel is supported via a door wheel and rotatable rollers provided above and below the floating beam and can be opened and closed with a very small operating force. In this case, the door panel is likely to collide with the side frame due to the kinetic inertia force. The door panel may gradually open and close due to external vibration. Guide frames, often
The slide frame and floating beam are made of aluminum material, but when the door panel is opened and closed, the rollers provided on the upper and lower surfaces of the floating beam roll at the same time, causing specific rolling noise and meandering of the roller when opening and closing. The upper part of the door panel is likely to rattle in the front-back direction.

The guide frame fixed to the opening frame, the slide frame fixed to the door panel, and the rail for the door roller fixed to the floor should be installed in parallel with each other. However, in an actual construction state, the respective members are often non-parallel, and in particular, if the door panel or the opening frame is warped, the preceding guide member cannot be properly installed. The inventor performed an operation test of the upper guide device based on such actual construction conditions. As a result, when the guide members are non-parallel when viewed from the top and front, or when they are parallel but are displaced back and forth, a tilting moment acts on the floating beam via the lower roller, It was confirmed that the entire floating beam receiving the moment tilted in the vertical direction or the front-back direction with the upper roller serving as a fulcrum, and the lower roller came off the slide frame of the door panel.

The slide frame fixed to the door panel has a section C
When the lower roller is formed of a shape member, at least the upward movement of the lower roller is restricted, and the lower roller can be prevented from coming off the slide frame. However, in this case, the lower roller needs to be assembled to the slide frame from the side end opening,
The door panel cannot be erected from the lower surface side with respect to the upper guide device, and it takes much time and labor for construction. In addition, since a large frictional resistance acts between the upper roller and the guide frame or between the lower roller and the slide frame, each roller bites into the guide groove during the opening of the door panel, and the door panel cannot be further opened. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an upper guide device for a sliding door which can be applied to a room where an atmosphere is important, such as a living room or a private office, without a sense of incongruity. An object of the present invention is to minimize the kinetic inertia of the door panel when the door panel is suddenly opened and closed, and to minimize the collision of the door panel with the side frame, even when external vibration is applied. It is another object of the present invention to provide an upper guide device for a sliding door capable of holding a door panel at an arbitrary open / close position so as not to move.

[0010] An object of the present invention is to prevent the slider on the lower surface of the floating beam from coming out of the sliding frame of the door panel even when the guides constituting the telescopic beam are installed in a non-parallel manner in the construction state. Is to do. SUMMARY OF THE INVENTION An object of the present invention is to provide an upper guide device suitable for an outset type sliding door capable of quietly opening and closing a door panel without generating noise when the door panel is opened and closed and without rattling at an upper portion of the panel.

[0011]

The upper guide device of the present invention is directed to a sliding door in which a door panel 1 is supported by a lower rail 3 provided below an opening surface so as to be openable and closable, as shown in FIG. And The upper guide device has an opening frame 6 as shown in FIG.
, A slide frame 8 fixed to the door panel 1, and a floating beam 9, which is disposed between the frames 7.8 and is supported by the guide frame 7 so as to be able to slide back and forth in the left-right direction. Become.

As shown in FIG. 3, the guide rails 11 of the guide frame 7 are provided at two upper surfaces on the closing start end side of the floating beam 9.
An upper sliding body 22 that is slid and guided in a surface contact state is provided, and a slider 24 that is moved and guided by the slide frame 8 is fixed to two lower surfaces on the opening start side of the floating beam 9. The inner surface of the slide frame 8 is brought into contact with the slider 24 during the opening of the door panel 1 to move the floating beam 9 together with the slide frame 8, and the opening contacting tool 20 during the closing of the door panel 1. A closing abutment 21 for contacting and moving the floating beam 9 with the slide frame 8 is provided. The slide frame 8 is formed of a frame having a U-shaped cross section that opens upward as shown in FIG. 1, and is inserted into and engaged with the slider 24 from below. In this engagement state, the slider 24 is brought into linear contact with the front and rear walls of the inner surface of the slide frame 8.

More specifically, as shown in FIGS. 5 and 6, a pair of resistance pieces 27 that are pressed against the front and rear walls of the guide rail 11 are integrally formed on the front and rear side surfaces of the upper sliding body 22, respectively. The pair of resistance pieces 27 are formed of cantilevered elastic arms extending in the opening direction and the closing direction of the upper sliding body 22. As shown in FIG. 7, the slider 24 is formed in a roller shape, and the circular arc surface of the sliding portion 29 is brought into line contact with the front and rear walls of the inner surface of the slide frame 8.

[0014]

When the door panel 1 in the closed position is opened, the slide frame 8 is guided by the floating beam 9 via the slider 24, so that the door panel 1 can be prevented from rattling back and forth. When the door panel 1 is opened to some extent,
As shown in FIG. 4, an open contacting device 20 provided on the slide frame 8
Abuts on the slider 24 to move the floating beam 9 together. Thereafter, the upper sliding body 22 slides along the guide rail 11 of the guide frame 7, and the floating beam 9 and the slide frame 8
And projecting laterally from the guide frame 7 to support the upper part of the door panel 1.

When the door panel 1 is completely opened, the closing start end of the floating beam 9 is located inside the guide frame 7, and the upper slide 22 is supported by the guide rail 11. When the door panel 1 is closed to the right in FIG. 4 from this state, first, only the door panel 1 and the slide frame 8 move, and after a certain movement, the closing abutment 21 contacts the slider 24 of the floating beam 9. And move it with you. When the door panel 1 is completely closed, the floating beam 9 and the slide frame 8 are returned and stored in the lower inner surface of the guide frame 7.

The floating beam 9 and the guide frame 7 and the floating beam 9 and the slide frame 8 are always in contact with each other via the upper sliding body 22 and the slider 24, respectively. Therefore, when the door panel 1 is opened and closed, sliding frictional resistance is generated between the upper sliding body 22 and the guide frame 7 and between the slider 24 and the sliding frame 8. This sliding friction resistance is sufficiently larger than the rolling resistance of a roller or the like. Therefore, even when the door panel 1 is rapidly opened and closed, the kinetic inertia of the door panel 1 can be gradually reduced. In particular, a resistance piece 27 is provided on the upper sliding body 22 and these resistance pieces 27 are attached to the guide rail 1.
1, the frictional resistance of the sliding body 22 is increased, and the kinetic inertia of the door panel 1 can be effectively eliminated. At any open position, the door panel 1 can be well prevented from moving in the opening direction or the closing direction. When the door panel 1 is opened and closed, no rolling noise is generated.

For example, when the guide frame 7 and the slide frame 8 are non-parallel when viewed from the upper side, when the door panel 1 is opened halfway, the direction of the forward and backward displacement of the two frames 7, 8 is as follows. The opposite moment acts on the floating beam 9 via the slider 24. At this time, the floating beam 9
In order to prevent the upper sliding body 22 from tilting in the direction in which a moment acts with the contact portion between the upper sliding body 22 and the guide frame 7 as a fulcrum, the upper sliding body 22 is slidably guided by the guide frame 7 in a surface contact manner, and is idle. It restricts the beam 9 from tilting up and down and back and forth.

Further, the slider 24 is brought into linear contact with the slide frame 8 so that the position and posture deviation between the slide frame 8 and the floating beam 9 is absorbed by the contact portion of the slider 24. As a result, it is possible to prevent the component force in the direction of lifting the floating beam 9 from acting on the floating beam 9 due to the previous moment, and except when the parallelism between the guide frame 7 and the slide frame 8 during construction is abnormally low, the door panel It is possible to prevent the slider 24 from slipping out when opening and closing 1. By the way, in the case of the floating beam that rotatably supports each of the upper roller and the lower roller according to the above proposal,
The floating beam can be tilted by the amount of the vertical and longitudinal rolling gaps between each roller and the guide groove, and by opening the door panel after the tilting moment begins to act, the moment in the direction to increase this tilting is increased. Works, so that the lower roller easily comes out of the slide frame.

The reason why the slider 24 is formed in a roller shape is to facilitate the assembling of the slider 24 to the floating beam 9 and merely by fixing the slider 24 without considering the assembling posture, the sliding portion thereof is formed. 2
9 can be brought into contact with the slide frame 8 in line contact.

The lock 4 can be unlocked by rotating a handle 5 also serving as a handle for opening and closing the door panel 1.

An upper guide device is provided along the upper edge of the opening frame 6 to guide the door panel 1 to open and close in the left-right direction while restricting tilting in the front-rear direction. The upper guide device is disposed between a guide frame 7 fixed to the upper outer surface of the opening frame 6, a slide frame 8 fixed to the upper end surface of the door panel 1, and both frames 7.8. And a floating beam 9 which is guided and supported so as to be able to move back and forth.

In FIG. 3, the guide frame 7 is formed of a U-shaped aluminum member having a U-shaped cross section which opens downward, and a C-shaped guide rail 11 which opens downward on the inner surface of its upper wall.
Are provided integrally. Caps 13 and 14 each made of a plastic molded product are press-fitted and fixed to both left and right ends of the guide frame 7. Of these two caps 13 and 14, the left cap 13 is formed in a gate shape in a side view so that the slide frame 8 and the floating beam 9 can move back and forth with respect to the guide frame 7. Stoppers 15 and 16 for fixing the limit of the movement of the floating beam 9 are fixed to the inner surface of the upper wall of the guide rail 11 near the left and right ends so as to protrude downward. The stoppers 15 and 16 are formed of rubber blocks, and exert a buffering function when an upper sliding body 22 described later collides.

As shown in FIG. 3, the slide frame 8 is formed of an aluminum frame having a U-shaped cross section and opening upward, and relatively slides and guides a slider 24 described later. The cross-sectional outer dimension of the slide frame 8 is set slightly smaller than the cross-sectional outer dimension of the guide frame 7, and the entire slide frame 8 is housed inside the guide frame 7. In this housed state, the slide frame 8 is vertically opposed to the guide rail 11 with an appropriate interval. An opening contact 20 and a closing contact 21 are respectively fixed near the left and right ends on the inner surface of the bottom wall of the slide frame 8. These contacts 20 and 21 are similar to the stoppers 15 and 16. It is made of rubber block.

The floating beam 9 is formed of a hollow metal frame as shown in FIG. 3, and an upper sliding body 22 which slides along the guide rail 11 is provided at two places on the upper surface on the right side in FIG. A slider 24 that slides relatively along the slide frame 8 is fixed to a shaft 25 at two lower surfaces on the opening start end side.

5 and 6, the upper sliding body 22 is made of a flat rectangular parallelepiped block-shaped plastic molded product.
The sliding pieces 26 that are slid and guided are respectively extended back and forth, and a pair of left and right resistance pieces 27 are integrally formed between the left and right sliding pieces 26 on each front and rear surface. The upper surface and the lower surface of the block portion and the sliding piece 26 are respectively reduced in thickness to reduce the volume, and holes 28 for receiving the shaft 23 are provided at two places on the left and right of the reduced thickness portion.

On each of the front and rear surfaces of the upper sliding body 22, a pair of left and right resistance pieces 27 are cantilevered elastic arms extending in opposite directions to each other as shown in FIGS. Each of the front and rear surfaces of the guide rail 1
A frictional resistance is generated by pressing against the inner surfaces of the front and rear walls. For this reason, the distance between the front and rear surfaces of the sliding piece 26 is set to be equal to or slightly smaller than the inner front and rear dimension of the guide rail 11, while the distance between the front and rear surfaces of the resistance piece 27 is It is set slightly larger than the inner dimension of the rail 11 before and after the inner method. The sliding piece 26 regulates the resistance piece 27 from being deformed more than necessary, and regulates the tilt of the floating beam 9. It should be noted that the greater the distance between the front and rear surfaces of the resistance piece 27, the greater the frictional resistance is obtained. However, with this, the operational resistance when opening and closing the door panel 1 is also increased, so that a certain degree of frictional resistance can be exhibited. The frictional resistance of the resistance piece 27 is set so that the door panel 1 can be opened and closed without any trouble. As shown in FIG. 1, a pair of ribs 32 are provided on the front and rear surfaces of the upper sliding body 22 so as to always contact the ceiling wall of the guide rail 11 to prevent the floating beam 9 from tilting upward.

In FIG. 7, the slider 24 is made of a convex roller-shaped plastic molded product, and has a sliding section 29 having a circular cross section guided by the sliding frame 8 in the lower half thereof. The diameter of the sliding portion 29 is set to be equal to or slightly smaller than the inner dimension of the front and rear walls of the slide frame 8. The circular outer peripheral surface of the portion 29 contacts simultaneously with the front and rear walls of the slide frame 8. The slider 24 is fixed non-rotatably by a shaft 25 caulked to the floating beam 9.

As shown in FIG. 1 and FIG.
By fitting 2 into the guide rail 11 from the side end of the guide frame 7, the entire floating beam 9 is slidably guided with respect to the guide frame 7 so as to be able to move back and forth. In this assembled state, the resistance piece 27 of the upper sliding body 22 is in pressure contact with the front and rear inner wall surfaces of the guide rail 11. Move the idle beam 9 to the guide frame 7
Then, the stoppers 15 and 16 are caulked and fixed to the guide frame 7, and the guide frame 7 and the floating beam 9 are assembled inseparably. Thereafter, the door panel 1 is inserted into the guide frame 7 from the lower surface side, and the slide frame 8 is engaged with the slider 24 of the floating beam 9 from the lower surface side to hold the door panel 1 so as not to be able to tilt forward and backward. As described above, in a state where the door panel 1 is guided and supported by the upper guide device, the sliding portion 29 of the slider 24 comes into contact with the front and rear walls of the slide frame 8 to regulate the upper front and rear position of the door panel 1. The lower end face is close to the inner bottom wall of the slide frame 8 (see FIG. 1).

According to the upper guide device configured as described above, when the door panel 1 is opened from the closed position to the left in the drawing, first, only the slide frame 8 is guided by the slider 24 and moves. When the opening is almost half, the opening contact tool 20 contacts the slider 24 of the floating beam 9 to move the floating beam 9 together. At this time, the resistance piece 27 and the rib 32 of the upper sliding body 22 are
1 to generate frictional resistance. Therefore, even when the door panel 1 is opened vigorously, the kinetic inertia of the door panel 1 is eliminated, and the moving speed of the door panel 1 can be gradually reduced.

When the door panel 1 is completely opened, as shown in FIG. 4, the left stopper 15 receives the upper sliding body 22, and prevents the floating beam 9 from moving beyond this position. I do. In this state, the right half of the floating beam 9 is supported by the guide frame 7, and the left half projects to the side of the guide frame 7 to support the slide frame 8. Actually, as shown in FIG. 2, the projecting portion of the floating beam 9 is accommodated in the groove for accommodating the slide frame 8 of the door panel 1, so that it cannot be seen from the outside, and the door panel 1 slides. A feeling of being supported only by the frame 8 is exhibited.

When the door panel 1 is closed to the right side in the figure from the above state, first, only the slide frame 8 is moved to the slider 2.
4 moves to the closing side. In some cases, the floating beam 9 moves together. When the door panel 1 is closed nearly halfway, the closing contact 21 provided on the opening start side comes into contact with the left slider 24 to move the floating beam 9 together. When the door panel 1 is completely closed, the floating beam 9 and the slide frame 8 enter the guide frame 7 and are concealed, so that the appearance can be improved. Accumulation of dust on the slide frame 8 and the floating beam 9 can be prevented well. The right stopper 16 contacts the upper sliding body 22 and regulates the retreat limit of the floating beam 9 when the floating beam 9 is pushed out by the slide frame 8 and moves forward.

In addition to the above, the guide frame 7 and the slide frame 8 may be formed by press-formed metal frames. The upper guide device of the present invention is also applicable to a double-door type sliding door that opens and closes two door panels 1 to the left and right. The slider 24 is formed in a hexagonal shape as shown in FIG. 8A, and its front and rear protrusions are brought into linear contact with the slide frame 8, or as shown in FIG. It can be formed by two metal pins that contact the front and rear walls of the slide frame 8. In short, any configuration is possible as long as the slider 24 can simultaneously make line contact with the front and rear walls of the slide frame 8.

[0033]

According to the upper guide device of the present invention, the door panel 1 is provided.
Only when the door is opened, the slide frame 8 and the floating beam 9 protrude from the guide frame 7 and support the upper portion of the door panel 1 so as not to be able to tilt forward and backward. When the door panel 1 is closed, the slide frame 8 and the floating beam 9 are retracted and accommodated in the lower inner surface of the guide frame 7 to prevent them from protruding from the wall surface adjacent to the opening surface. Therefore, it is possible to apply the present invention to a room where the use has been hesitated, without impairing the atmosphere in the room, and it is suitable for an outset type sliding door.

The floating beam 9 is provided with an upper sliding body 22 and a slider 24, and the floating beam 9 is connected to the guide frame 7 and the slide frame 8 via these both 22 and 24 so as to be relatively slidable. 9 can be given an appropriate sliding friction resistance. Thereby, the kinetic inertia force when the door panel 1 is suddenly opened and closed is gradually eliminated, and it is possible to prevent the door panel 1 from colliding with a side frame or the like.
It is also possible to prevent the door panel 1 from gradually opening and closing due to external vibration. At the same time, noise is generated when the door panel 1 is opened and closed, and the upper part of the panel is rattled back and forth.
The door panel 1 can be opened and closed quietly.

The upper sliding body 22 of the floating beam 9 is
The floating beam 9 is prevented from tilting in the up-down direction, the front-rear direction, and the like with respect to the guide frame 7. Further, the slider 24 is brought into linear contact with the slide frame 8 so that the displacement of the slide frame 8 can be absorbed as much as possible by the contact portion of the slider 24.
This prevents the moment due to the displacement of the position of the slide frame 8 from acting on the floating beam 9 with a component force in the direction of lifting the floating beam 9, and can prevent the slider 24 from coming off the slide frame 8. Even when there are variations in the assembly at the time, the door panel 1 can be opened and closed without any trouble.
