[0001]
BACKGROUND OF THE INVENTION The present invention relates to a sliding door in which a plurality of sliding doors are stacked side by side, slidably suspended in an opening and closing direction at an upper portion of a door frame, and a sliding door on the near side is slid. The present invention relates to an interlocking-type hanging door device in which sliding doors sequentially slide and interlock to open and close an opening.
[0002]
2. Description of the Related Art Conventionally, this type of interlocking type hanging door apparatus has a hanging body 1 mounted on a door end side and a door end side of upper end surfaces of two sliding doors a and b, as shown in FIG. The door roller 1a of the suspended body 1 is rollably engaged with the guide rail 2 fixed to the upper part of the door frame e to suspend the sliding doors a and b. It has a structure that is arranged to overlap.
[0003]
In such a conventional interlocking type suspension door device, channel members 3 and 4 are recessed at the lower end surfaces of the sliding doors a and b to form guide grooves 3a and 4a in the longitudinal direction, while the guide grooves 3a and 4a are formed. A guide mechanism g that guides the lower sides of the sliding doors a and b by rotatably fitting the guide rollers 5 and 6 into the 4a is provided. In this guide mechanism g, the guide roller 5 for guiding the first sliding door a on the back side with respect to the wall w is erected on the floor f at the door tip side of the sliding door storage position d, and the second sliding door b on the front side. Of the angle plate 7 fixed to the door end side of the first sliding door a stands upright.
[0004]
Then, at the time of opening and closing, when the second sliding door b on the front side is slid in the opening and closing direction with respect to the wall w, the first sliding door a on the back side slides in conjunction therewith to open and close the opening. It has become.
[0005]
However, in the conventional interlocking type suspension door apparatus, the upper side of the sliding doors a and b engages with the guide rail 2 at two points on the left and right sides in the longitudinal direction when the door is opened and closed. The lower side has a structure in which the guide rollers 5 and 6 engage and guide the guide grooves 3a and 4a at only one point on each side. Therefore, for example, when the sliding doors a and b are pulled out and slid when the doors are closed, as shown by a chain line in FIG. However, as a result, there is a problem that the operability of opening and closing the sliding door is extremely poor.
[0006]
Therefore, conventionally, as shown in FIG. 10, for example, as shown in FIG. 10, guide members 8 each pivotally supporting a door roller 8a are recessed at lower end surfaces of sliding doors a, b, and c. On the floor f below the opening, guide rails 9 are laid on the traveling paths (sills) of the sliding doors a, b and c, and the door wheels 8a of the guide body 8 are engaged with the concave grooves 9a of these guide rails 9. In some cases, the sliding doors a, b, and c are guided so as not to swing sideways when they are opened and closed.
[0007]
However, in this conventional interlocking type suspension door device, it is necessary to form a plurality of long grooves for rails on the sill, and to lay the guide rails 9 therein, which requires much labor for constructing the entire guide mechanism. In addition, there is a problem that the guide rails 9 protrude above the floor surface f, and the steps thereof impede the passage of a wheelchair or the like and hinder barrier-free operation.
[0008]
Therefore, an object of the present invention is to reduce the trouble of assembling a guide mechanism at the lower part of a sliding door in an interlocking type hanging door device, and to prevent the sliding door from swinging at the time of opening and closing without obstructing the barrier-free operation at the opening. An object of the present invention is to improve the opening and closing operability by reliably preventing the opening and closing operation.

Therefore, in order to achieve the above-mentioned object, the invention according to claim 1 slides a plurality of sliding doors in the opening and closing directions, respectively, as shown in the embodiment shown below. While hanging at the upper part of the door frame as much as possible and arranging side by side at the sliding door storage position, when opening and closing, sliding the sliding door on the front side while guiding the lower part of each sliding door with the guide mechanism, In the interlocking type sliding door device in which the sliding doors sequentially slide and interlock to open and close the opening, the guide mechanism is slidably connected to each other by engaging the engaging portions of the opposing long rails. The first sliding door, which is configured by using a rail, and which is located at the innermost side of the sliding door housing position when opened among the sliding doors, is fixed to a rail body on one side of the slide rail in a length direction of a lower end surface thereof. And that one side The rail body is engaged with the rail body on the other side fixed to the sliding door storage position on the floor surface, and the second sliding door other than the first sliding door is fixed to the rail body on one side in the longitudinal direction of the lower end surface thereof. The slide rail is attached with the other-side rail body facing downward, and the other-side rail body is connected to an adjacent sliding door via a joint member.
[0010]
According to a second aspect of the present invention, in the interlocking type hanging door device according to the first aspect, the slide rail used for the guide mechanism is curved inward on both side edges, for example, as shown in the following illustrated embodiment. The outer rail having the engaged engaging portion and the inner rail having the outwardly curved engaging portion on both side edges are engaged and slid in the engaging portion via a number of balls held by a ball retainer. It is characterized by being freely connected.
[0011]
Embodiments of the present invention will be described below with reference to the drawings.
[0012]
FIG. 1 is a perspective view showing an overall configuration of an interlocking type hanging door device which is an example of the present invention. The interlocking type hanging door device of the illustrated example is a double-sliding type sliding door device that opens and closes an opening S by sliding two sliding doors A and B in an interlocking manner. Sliding door A, the sliding door on the near side in the figure is referred to as a second sliding door B.
[0013]
In the first sliding door A, the suspended bodies 10 and 11 are mounted on the left side and the right side of the door at the upper end surface, and the second sliding door B is similarly mounted on the upper side. And suspension bodies 12 and 13 are mounted on the side of the door.
[0014]
To the suspension bodies 10 and 11 of the first sliding door A, doors 16 and 17 are vertically assembled on one side of mounting plates 14 and 15 fixed to the upper end surfaces of the sliding doors, and pulleys 18 and 19 are mounted on the other side. Installed sideways. Doors 22 and 23 are vertically assembled on suspension plates 12 and 13 of the second sliding door B, respectively, on mounting plates 20 and 21 fixed to the upper end surfaces of the sliding doors. Between the pulleys 18 and 19 of the first sliding door A and the wire holder 24 fixed on the mounting plate 21 of the second sliding door B, one end-shaped wire 25 is wrapped around in a reciprocating manner. The wire 25 is connected at both ends to a retaining ring 26 fixed to the wall W, and by holding the middle of the wire with the wire holder 24 on the second sliding door A, the two sliding doors A and B are connected. The structure is linked so that it can slide back and forth in conjunction.
[0015]
Further, the first sliding door A rotatably engages the door rollers 16 and 17 with a guide rail 27 having a U-shaped cross section fixed to the upper part of the door frame E and slidably in the opening and closing direction. The second sliding door B rollably engages the door rollers 22 and 23 with a guide rail 28 fixed to the upper part of the door frame E in parallel to the side of the guide rail 27, and similarly slidably suspends. . As shown in FIG. 2, when the sliding doors A and B are opened, two sliding doors A and B are arranged side by side with respect to the wall W at the sliding door storage position D formed on the side of the opening S.
[0016]
On the other hand, as shown in FIG. 1, the interlocking type hanging door device is provided with a guide mechanism G for guiding the sliding doors A and B so that they do not swing sideways during the opening and closing operation, as shown in FIG. The guide mechanism G in the illustrated example is configured using a plurality of long metal slide rails as shown in FIG. The slide rail alone includes an outer rail 32 having an inwardly curved engaging portion 32a on both side edges, and an inner rail 33 having an outwardly curved engaging portion 33a on both side edges. At 33a, a plurality of metal balls 35 rotatably held by a ball retainer 34 are engaged with each other, so that both rails 32 and 33 are slidably connected to each other.
[0017]
Therefore, in the guide mechanism G, one slide rail alone is used, and as shown in FIG. 4, an outer rail (one side rail body) 32 is provided in a guide long groove 29 recessed in the lower end surface of the second sliding door B. Are fixed with screws, and the inner rail (rail body on the other side) 33 is arranged downward, and is attached as a slide rail R2 as a whole.
[0018]
Further, in the guide mechanism G, in order to guide the first sliding door A, two slide rails alone are used, and the inner rails 33 and 33 'are overlapped back to back and welded to assemble one slide rail R1. . Then, the outer rail 32 of one slide rail alone (one side rail body) is fixed to the guide long groove 30 recessed in the lower end surface of the first sliding door A with a screw. The outer rail 32 ′ of the other slide rail alone (the other rail body) is fixed along the wall W to the sliding door accommodating position D (see FIG. 1) on the floor surface F with screws. Therefore, as shown in FIG. 5, the slide rail R1 allows the integrated inner rails 33, 33 'to slide freely on the lowermost fixed outer rail 32', and furthermore, the inner rails 33, 33 'and the outer rail 32. Are slidable relative to each other in a two-stage slide configuration, and the slide stroke is lengthened accordingly.
[0019]
Further, as shown in FIGS. 1 and 4, the guide mechanism G connects the other end 40 b of the joint member 40 in which one end 40 a is screwed to the door end side of the lower end surface of the first sliding door A to the inner side of the second sliding door B. The sliding doors A and B are connected to each other via the joint member 40 and screwed to the rail 33. The joint member 40 in the illustrated example is formed of a metal plate formed by bending one end 40a into an L-shaped plate.
[0020]
By the way, when operating the interlocking type hanging door device having the above-described configuration and pulling out the sliding doors A and B accommodated in the sliding door accommodating position D and closing the opening S, first, the second sliding door B on the near side is first attached to the handle 41. And pull it out. Then, as shown in FIG. 1, the wire 25 is sent in one direction indicated by an arrow in the figure and rotates, whereby the first sliding door A is pulled out with a slight delay in conjunction with the movement of the second sliding door B. . At this time, the sliding doors A and B are rolled on the guide rails 27 and 28 on the upper side and guided by the guide rails 27 and 28 at the same time as the guide mechanism on the lower side. Slide while guiding with G.
[0021]
At that time, in particular, in the guide mechanism G, the inner rails 33 ′ slide on the outer rail 32 ′ of the slide rail R 1, and then the first sliding door A moves the outer rail 32 against the integral inner rail 33 ′. , Whereby the first sliding door A is pulled out linearly without causing lateral swing. Further, the second sliding door B slides on the inner rail 33 of the slide rail R2 via the outer rail 32, whereby the second sliding door B is also pulled out linearly without causing lateral swing. Thus, the sliding doors A and B are sequentially pulled out in conjunction with each other, and the opening S is closed as shown in FIG.
[0022]
On the other hand, when the opening S is opened, when the second sliding door B is pulled back with the handle 41, the wire 25 is sent in the other direction and rotated, whereby the second sliding door B is opened. The first sliding door A slides toward the sliding door storage position D with a slight delay in conjunction with the movement. At this time, as in the case of the closing, the sliding doors A and B are guided by the guide mechanism G on the lower side thereof and are linearly pulled back, thereby preventing the occurrence of the lateral shake.
[0023]
By the way, in the illustrated embodiment described above, an example of a hanging door device having two sliding doors is shown. However, in the present invention, it is needless to say that the present invention can be applied to a hanging door device having two or more sliding doors. . FIG. 7 shows a triple-type hanging door device according to the present invention having three sliding doors.
[0024]
The guide mechanism G of the triple-type hanging door device uses one slide rail alone for guiding the second sliding door B 'on the front side, similarly to the adjacent second sliding door B. The outer rail 32 is fixed to the guide long groove 31 recessed in the lower end surface of the ′ by a screw, and the inner rail 33 is arranged downward, and is attached as a slide rail R3 as a whole. Then, the other end 40b of the joint member 40 having one end 40a screwed to the tip side of the second sliding door B is screwed to the inner rail 33 of the slide rail R3, and the second sliding door BB is connected via the joint member. 'Are connected.
[0025]
In the above-described guide mechanism G, the slide rail R1 for guiding the first sliding door A is constructed by assembling two slide rails as shown in FIG. 3, but is similar to the second sliding door BB ′. By using one slide rail alone, for example, one outer rail 32 is fixed to the sliding door storage position D on the floor F, and the other inner rail 33 is fixed to the lower end face of the first sliding door A, and It is also possible to adopt a configuration in which they are engaged. Further, in the illustrated embodiment described above, the outer rail 32 and the inner rail 33 are engaged with each other as the slide rails R1, R2, and R3 of the guide mechanism G via a large number of balls 35 held by a ball retainer 34 and connected. In the present invention, any slide rail other than the illustrated example described above may be used as long as the slide rail has a configuration in which the engagement portions of the opposed long rail bodies are engaged with each other and slidably connected. Is not excluded.
[0026]
According to the present invention configured as described above, the following effects can be obtained.
[0027]
According to the first aspect of the present invention, one of the plurality of sliding doors has a first sliding door on the far side to which one side rail body of the slide rail is fixed at the lower end surface, and the one side rail body is connected to the floor. Engage with the other side rail body fixed to the sliding door accommodation position on the surface, and attach the one side rail body to the lower end face of the second sliding door on the near side other than the first sliding door, and turn the other side rail body downward. Arrange and connect the other side rail body with the adjacent sliding door via a joint member to form a guide mechanism, and when opening and closing, slide the rail body of the slide rail of the guide mechanism to guide each sliding door linearly As a result, the sliding door can be smoothly slid in the opening and closing direction without causing a lateral shake, and as a result, the operability of opening and closing the sliding door can be further improved.
[0028]
Further, according to the first aspect of the present invention, since a part of the rail body of the slide rail is fixed to the sliding door housing position next to the opening that does not hinder the passage, the sliding door is guided. As described above, it is possible to simplify the assembly of the guide mechanism by eliminating the trouble of laying a plurality of guide rails on the sill part, and to sufficiently meet the demand for barrier-free at the opening.
[0029]
According to the second aspect of the present invention, a slide rail having a structure in which the outer rail and the inner rail are slidably connected by engaging each other with a plurality of balls held by a ball retainer at an engagement portion of each other.
