Description

  The present invention relates to a suspension type folding in which a suspension shaft is arranged in a vertical direction across a runner having a roller only on one side of a runner body and an attachment member for attaching the runner and a suspension type folding door. The present invention relates to a door suspension vehicle device, a suspension type folding door that is suspended from an upper rail by the suspension vehicle device, and a method of suspending the folding door from an upper rail.

  In order to attach a folding door to the lower end of the suspension shaft, a runner that can travel along the upper rail and a suspension shaft that can be moved up and down with respect to the runner has been conventionally installed on the upper rail in advance. Is installed, and the attachment member attached to the folding door is fitted to the suspension shaft suspended from the runner installed on the upper rail (for example, see Patent Document 1). ).

The runners in the folding doors that are attached in this way are usually provided with rollers on both sides of the runner body, most of which are of the so-called four-wheel type.
On the other hand, a runner having a roller only on one side of the runner main body and a device for hanging a folding door on the runner have already been proposed (see, for example, Patent Document 2).

Japanese Patent No. 3764735 (paragraph 0030, FIGS. 1 to 3)

Japanese Patent Publication No. 8-23246 (FIG. 2)

The suspension device described in Patent Document 1 has a fatal defect that the runner and the mounting member are separate, and the number of parts for connecting them is increased, which increases the cost.
In addition, since it is necessary to fit the mounting member attached to the folding door to the suspension shaft suspended from the runner installed on the upper rail, it is necessary to do it while lifting the heavy folding door, Not only is it time-consuming, but there is a drawback that it is extremely difficult to work.

Moreover, since it is a system which fits an attachment member to the suspension shaft suspended from the runner installed in the upper rail, there also exists a fault that a precision is requested | required of each member.
In addition, when the runner has a problem such as a difference in direction or a defect / failure, there is a disadvantage that the runner must be taken out by removing the upper rail once constructed from the opening where the folding door is to be attached.

  On the other hand, since the runner in the suspension device of patent document 2 needs two for right side and left side, there also exists a fault that a cost increases also in this case.

  And in the conventional case, the folded folding door was brought into the opening parallel to the vertical surface of the opening where it was installed, so it was difficult for one person to do the work alone, above the upper rail. When the gap with a certain top surface is limited, or when the width of the folded folding door is wide, there is a work defect that it is difficult to bring the folding door through the opening.

  In order to eliminate all of these drawbacks, the present invention provides a suspension shaft in which a runner installed on an upper rail and an attachment member for attaching a suspension type folding door are disposed in a vertical direction across the two. It is integrated through.

  That is, in the present invention, a suspension shaft is arranged in a vertical direction across a runner provided with a roller only on one side of the runner body and an attachment member for attaching the runner and the suspension folding door, The runner and the mounting member were integrated with each other via the suspension shaft.

  The suspension vehicle device of the hanging type folding door according to the present invention has a hanging shaft in which a runner installed on the upper rail and an attachment member for attaching the hanging type folding door are arranged in a vertical direction across the two. Therefore, the number of parts for connecting them can be omitted, thereby reducing the cost.

  In addition, if the suspension vehicle device of the hanging type folding door according to the present invention is used, the runner can be attached to the folding door in advance, so that it is installed on the upper rail while lifting the heavy folding door as in the conventional case. Since the operation of fitting the attachment member attached to the folding door to the suspension shaft suspended from the runner is unnecessary, the labor can be saved.

  In addition, as in the conventional case, the accuracy of each member required to fit the attachment member attached to the folding door to the suspension shaft suspended from the runner installed on the upper rail is required. It never happens.

  Furthermore, if the suspension vehicle device of the hanging type folding door according to the present invention is used, even if the runner has a problem such as a difference in direction or failure / failure, the runner can be removed simply by lifting the folding door from the upper rail once constructed. Since it can be taken out, it is not necessary to remove the upper rail once it has been constructed as in the conventional case.

While the runner is symmetric with respect to the suspension shaft, the mounting member is preferably asymmetric with respect to the suspension shaft and with the same shape on both sides.
In this case, since there is no direction of the runner in the front-rear direction, mistakes in the wrong direction of the runner attachment can be reduced, and the suspension device can be turned over so that the suspension device can be used on both the left and right sides.

The distance from the axis of the suspension shaft to one end surface of the mounting shaft that is asymmetrical with respect to the suspension shaft is slightly smaller than the distance from the axis of the suspension shaft to one end surface of the runner. It is good to keep it small.
If this suspension type folding door suspension device is attached to the left and right sides of two adjacent folding doors, a gap can be created between the end faces of the two adjacent folding doors. Even if it is expanded, it is possible to avoid collision of both end faces.

In the mounting member, a slide member movable along an inclined guide surface that forms a predetermined angle with respect to a horizontal plane is mounted near the lower end of the suspension shaft, and the slide member is moved by an operation from the end surface of the mounting member. It is preferable to move the attachment member in the vertical direction with respect to the runner along the suspension shaft by the movement.
In the case of using the suspension vehicle device of the hanging type folding door, the mounting member is moved in the vertical direction with respect to the runner along the hanging shaft only by moving the slide member by an operation from the end face of the mounting member. Therefore, the vertical adjustment of the folding door with respect to the upper rail or the floor surface can be performed very easily.

It is preferable that the runner is provided with a lever that can protrude from the back surface, and the tip of the lever is engaged with the lower side of the upper rail on which the roller rolls to prevent the suspension device from falling off the upper rail.
In such a case, it is possible to reliably prevent the suspension device from falling off the upper rail only by operating the lever provided on the runner.

It is preferable that the opposing surfaces of the two runners fixed in the vicinity of the left and right corners on the upper side of the hanging type folding door are provided with engaging portions that can engage both ends of the rotation stop pin with each other.
When the engaging portions are provided on the opposing surfaces of the two runners, two ends of the rotation stopper pin are engaged with the respective engaging portions of the two runners in the folded state of the folding door. The runners are coupled to each other, and both runners can be prevented from rotating.

A protrusion may be formed on either one of the lever and the opposing surface in the runner body where the lever is disposed.
If this protrusion is formed at the above position, a click feeling can be obtained when the lever is rotated, and the lever can be prevented from rotating due to the vibration of the runner.

Further, in the present invention, the attachment members of any of the above-described suspension type folding door suspension vehicles are fixed in the vicinity of both the left and right corners on the upper side of the suspension type folding door, and rollers are provided only on one side of the runner body. The runner is integrated with the hanging type folding door via a hanging shaft that is arranged in a vertical direction across the runner provided and the mounting member.
In this case, since the runner is integrated with the hanging type folding door, the number of parts for connecting the mounting member for attaching the runner and the hanging type folding door can be omitted, thereby reducing the cost. You can go down.

Furthermore, in the present invention, in the state where the above-described hanging folding door is folded, it is tilted in the left-right direction with respect to the opening portion where the folding door is installed, and is also tilted in the front-rear direction of the opening portion. After bringing it into the opening, change the posture of the folding door from an inclined state to an upright state on both the left and right sides, and then fit the roller provided on only one side of the runner body into the upper rail from one side of the upper rail. .
When this hanging method is adopted, not only is it relatively easy for one person to perform the folding door installation work on the upper rail, but also when the gap with the top surface above the upper rail is limited or when folding is folded. Construction is possible even when the door is wide.

  According to the first aspect of the present invention, the number of parts for connecting the runner installed on the upper rail and the mounting member for mounting the hanging folding door can be omitted, thereby reducing the cost. Can do.

  Further, according to the invention described in claim 1, since the runner can be attached to the folding door in advance, it is suspended from the runner installed on the upper rail while lifting the heavy folding door as in the conventional case. In addition, since the operation of fitting the attachment member attached to the folding door to the suspension shaft is not necessary, the labor can be saved.

  In addition, according to the invention described in claim 1, it is not necessary to fit the mounting member attached to the folding door to the suspension shaft suspended from the runner installed on the upper rail. The accuracy of each member required for the above is not required.

  Furthermore, according to the first aspect of the present invention, even if the runner has a problem such as a difference in direction or a defect / failure, the runner can be taken out simply by lifting the folding door from the upper rail once constructed. There is no need to remove the upper rail once constructed as in the conventional case.

  Various examples of the suspension vehicle device of the hanging type folding door according to the present invention, an example of the hanging type folding door to which the suspension vehicle device is attached, and an example of a method of hanging the folding door, FIGS. 10 will be described in detail.

The suspended vehicle apparatus A illustrated here is a so-called two-wheel type in which two rollers 2 and 2 are provided only on one side of the runner body 1, as shown in FIGS. 1 (a) to 1 (c), FIG. 2 and FIG. This is a suspension vehicle device. The two rollers 2 and 2 are rotatably attached to only one side of one runner body 1 by a roller shaft 2a.
In addition, the runner 3 provided with the two rollers 2 and 2 only on one side of the runner body 1 is installed on one upper rail C and is provided only on one side of the runner body 1 as shown in FIG. Two rollers 2 and 2 are fitted in the groove c of the upper rail C. Therefore, the runner 3 can travel along the upper rail C.

A suspension shaft 5 is disposed between the runner 3 and the attachment member 4 for attaching the suspension type folding door B in the vertical direction, and the runner 3 and the attachment are connected via the suspension shaft 5. The member 4 is integrated.
Then, two suspension vehicles A and A are prepared, and the upper right corner portion of one door b of one hanging type folding door B and the upper left corner portion of the other door b are respectively attached to the mounting members 4, By fixing to 4 with a screw, one hanging type folding door B can be suspended directly under the upper rail C.

  In this way, the runner 3 installed on the upper rail C and the mounting member 4 for mounting the hanging type folding door B are integrated with each other via the hanging shaft 5 disposed in the vertical direction across the two. Therefore, both, that is, the number of parts for connecting the runner 3 and the mounting member 4 can be omitted, thereby reducing the cost.

  Moreover, when this suspension vehicle apparatus A is used, since the runner 3 can be previously attached to the suspension type folding door B, the runner is installed on the upper rail while lifting the heavy folding door as in the conventional case. Since the operation of fitting the attachment member attached to the folding door to the suspension shaft suspended from the door becomes unnecessary, the labor can be saved.

  In addition, as in the conventional case, the accuracy of each member required to fit the attachment member attached to the folding door to the suspension shaft suspended from the runner installed on the upper rail is required. It never happens.

  Furthermore, when this suspension vehicle device A is used, even if a problem such as a difference in direction or a defect / failure occurs in the runner 3, the runner 3 can be taken out simply by lifting the folding door B from the upper rail C once constructed. Since it is possible, it is not necessary to remove the upper rail C once constructed as in the conventional case.

In the suspended vehicle device A illustrated here, as shown in FIG. 1 (b), the runner 3 is symmetric with respect to the suspension shaft 5, while the attachment member 4 is horizontally aligned with the suspension shaft 5. It has an asymmetric shape and the same shape on both sides.
In such a case, since there is no front-back direction of the runner 3, it is possible to reduce mistakes in attaching the runner 3 in the wrong direction.
Moreover, when the suspension apparatus A shown in FIG. 1B is for the left side of the hanging type folding door B, that is, as shown on the left side of FIG. If this is the case, by turning the mounting member 4 upside down, as shown on the right side of FIG. 4, for the right side of the hanging type folding door B, that is, for the right side door b of the hanging type folding door B, Therefore, the suspension device A can be used for both left and right.

In addition, as shown in FIG. 1B, the suspension vehicle device A exemplified here is one end surface from the axis of the suspension shaft 5 of the mounting member 4 that is asymmetrical with respect to the suspension shaft 5. For example, the distance to the left end surface in FIG. 1 (b) is slightly smaller than the distance from the axis of the suspension shaft 5 of the runner 3 to one end surface, for example, the left end surface in FIG. It is getting smaller.
As shown in FIG. 5, the suspension vehicle devices A and A of the hanging type folding doors are adjacent to each other if they are attached to the left door b and the right door b of the two adjacent hanging doors B and B. Since a gap Y corresponding to at least twice the gap X can be generated between the left and right end faces of the two hanging folding doors B and B, the two hanging folding doors B and B are expanded respectively. Even if the doors are opened, it is possible to avoid collision between both end surfaces of the doors b adjacent to each other, that is, the right end surface of the left door b and the left end surface of the right door b.

Moreover, the suspension vehicle apparatus A illustrated here attaches the slide member 6 that can move along the inclined guide surface 4a that forms a predetermined angle with respect to the horizontal plane in the attachment member 4, near the lower end of the suspension shaft 5. The slide member 6 is moved by an operation from the end face of the attachment member 4, and the attachment member 4 can be moved vertically with respect to the runner 3 along the suspension shaft 5 by the movement. is there.
When this suspension vehicle device A is used, the attachment member 4 is moved in the vertical direction with respect to the runner 3 along the suspension shaft 5 only by moving the slide member 6 by an operation from the end face of the attachment member 4. Therefore, the vertical adjustment of the suspension type folding door B attached to the attachment member 4 can be performed very easily with respect to the upper rail C or the floor surface D (see FIG. 10).

Here, as shown in FIGS. 1 (d) and 6, a vertical adjustment member 7 is arranged from the right end surface of the mounting member 4 to the inside of the mounting member 4, and a screw 8 embedded on the right end side of the slide member 6. A nut 7a attached to the tip (left side) of the vertical adjustment member 7 is screwed together.
Accordingly, by operating from the rear end surface (right end surface) of the vertical adjustment member 7, the slide member 6 in the mounting member 4 is moved from the position shown in FIGS. 1 (d) and 6 (a) via the screw 8. As shown in FIG. 6 (b), it is moved to the left side of the figure and, conversely, by operating the vertical adjustment member 7 in the direction opposite to the previous direction, from the position of FIG. 6 (b), FIG. It can be moved to the right side of the figure as shown in FIG.

As described above, the slide member 6 moves along the inclined guide surface 4a that forms a predetermined angle with respect to the horizontal plane in the attachment member 4, so that the attachment member 4 is moved along the suspension shaft 5. Therefore, the vertical adjustment of the suspended folding door B attached to the attachment member 4 with respect to the upper rail C or the floor surface D (see FIG. 10) can be performed very easily. It can be carried out.
If a cross-shaped slit 7b is formed in the head of the vertical adjustment member 7, the vertical adjustment member 7 can be operated not only by a Phillips screwdriver but also by a flat-blade screwdriver, and there is no dedicated tool. For example, if there is a thin object such as a coin, the vertical adjustment member 7 can be operated.

Moreover, the suspension vehicle apparatus A illustrated here is provided with a lever 9 that can be protruded from the back surface of the runner 3, and its tip engages with the lower side of the upper rail C on which the rollers 2 and 2 of the runner 3 roll. Thus, the suspension device A can be prevented from falling off the upper rail C. That is, as shown in FIG. 7 (a), when the lever 9 is rotated counterclockwise, the tip of the lever 9 is not engaged with the lower side of the upper rail C and is not locked. On the other hand, as shown in FIG. 7 (b), when the lever 9 is rotated in the clockwise direction, the tip of the lever 9 is engaged with the lower side of the upper rail C, and a so-called locked state is obtained.
Therefore, the suspension device A can be reliably prevented from falling off the upper rail C simply by operating the lever 9 provided on the runner 3.

As shown in FIG. 8, two runners 3 and 3 are fixed in the vicinity of the upper left and right corners of the doors b and b of the hanging type folding door B. In the hanging device A illustrated here, As shown in FIGS. 1 to 3, 6 and 8 (a), both ends of the rotation stop pin 10 are engaged with the opposing surfaces of the runners 3 and 3, that is, the opposing surfaces of the runner main bodies 1 and 1, respectively. Engaging portions 1a and 1a that can be combined are provided.
When this engaging part 1a, 1a is provided in the opposing surface of the two runners 3, 3, as shown in FIGS. 1-3, 6 and 8 (a), the hanging type folding door B is In the folded state, by engaging both ends of the rotation stop pin 10 with the engaging portions 1a and 1a of the two runners 3 and 3, as shown in FIG. Are coupled to each other, and the runners 3 and 3 can be prevented from rotating with respect to the doors b and b of the hanging type folding door B.

In FIG. 8, the case where the hole which can insert both ends of the rotation stop pin 10 in the opposing surface of the runner main bodies 1 and 1 is formed, and this hole is each made into the engaging part 1a is illustrated. This is the simplest engaging portion 1a, but a gripping tool such as a chuck is provided in the back of the opposing surface of the runner main bodies 1 and 1, and both ends of the rotation stop pin 10 are gripped by both gripping tools. You may do it.
When this engaging portion is provided on the opposing surfaces of the two runners 3 and 3, both ends of the rotation stop pin 10 are respectively engaged with the respective engaging portions of the two runners 3 and 3 when the folding door B is folded. By engaging, the two runners 3 and 3 are coupled to each other, and both runners 3 and 3 can be prevented from rotating.

Moreover, in the suspended vehicle apparatus A illustrated here, as shown in FIG.1 (d), FIG.6 (a), (b), it opposes the upper side in the runner main body 1 in which the said lever 9 is arrange | positioned. Projections 11 are formed on the surface.
If the protrusion 11 is formed at this position, a click feeling can be obtained when the lever 9 is rotated, and the lever 9 can be prevented from rotating due to the vibration of the runner 3.
The position of the protrusion 11 may be formed on the lower facing surface in the runner body 1 where the lever 9 is disposed, or may be formed on either the upper or lower surface of the lever 9. In short, when the lever 9 is rotated, the protrusion 11 and any surface facing the protrusion 11 may collide to obtain a click feeling.

Thus, although various things were illustrated as the suspension vehicle apparatus A of this invention, as shown in FIG.4, FIG5 and FIG.8, the attachment member of the suspension vehicle apparatus A of one of the above-mentioned suspension type folding doors B is shown. 4 are fixed in the vicinity of the left and right corners on the upper side of the hanging type folding door B, respectively.
Then, the suspension type folding door B is connected to the suspension type folding door B via the suspension shaft 5 that is disposed between the runner 3 having the roller 2 only on one side of the runner body 1 and the mounting member 4 in the vertical direction. The runner 3 is integrated.
Thus, since the runner 3 is integrated with the suspension type folding door B, the number of parts for connecting the attachment member 4 for attaching the runner 3 and the suspension type folding door B can be omitted. This makes it possible to reduce costs.

Next, the hanging method of the hanging type folding door B exemplified above will be described in detail based on FIG. 9 and FIG.
First, as shown in FIGS. 10 (a) and 10 (b), the suspended folding door B illustrated above is folded, and the installation location of the folding door B is shown in FIG. 9 (a). While tilting in the left-right direction with respect to the opening E, it is brought into the opening E in a state tilted in the front-rear direction of the opening E as shown in FIG. Next, as shown in FIGS. 9 (b) and 10 (f), the posture of the folding door B is changed from a state where both left and right and front and back are in an upright state. Thereafter, as shown in FIG. 9 (c), the roller 2 provided only on one side of the runner body 1 is fitted into the groove c of the upper rail C from one side of the upper rail C. In addition, in FIG.9 (c), illustration of the suspension type folding door B is abbreviate | omitted.

Thus, the suspended folding door B can be suspended from the upper rail C. When this hanging method is adopted, not only the construction work of the folding door B on the upper rail C is relatively easy even by one person, but also when the gap with the top surface F above the upper rail C is limited, Construction is possible even when the folded folding door B is wide.
