Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a folding door, and more specifically, a first door which is openably and closably mounted on a frame constituting an opening.
And a second door body which is connected to the free end of the first door body via a hinge so as to be foldable with each other.

[Prior Art] As shown in FIGS. 10 and 11, a pair of front and back panels a and b are provided between a first and a second door body of a conventional folding door of this type. A so-called flash panel is used in which an aggregate composed of vertical frames c, d and a plurality of horizontal rails e, e ... installed in parallel with each other between the vertical frames c, d is used. By connecting the first and second door bodies configured as described above with a hinge (not shown) interposed therebetween, the first and second door bodies can be folded together and applied to a storage unit or the like. It is generally used as a device capable of narrowing the opening / closing trajectory of the entire door and widening the effective area of a room or the like (Japanese Utility Model Laid-Open No. 1-163692, Japanese Utility Model Laid-Open No. 1-138088 and See JP-A-64-23585).

[Problem to be Solved by the Invention] However, in this type of conventional foldable door, since the horizontal rail is also interposed at the upper and lower ends of the vertical frame, the height of the first and second door bodies is increased. The dimensions are fixed to the height of the vertical frame, and it is necessary to prepare a door body having each height dimension for each different height dimension of the opening, and there is no versatility of the door body for each opening Was.

On the other hand, the front and back panels a and b and the horizontal rail e are cut off at the A'-A 'cut line in FIG. 10, or the front and back panels a and b and the vertical frame c and d are cut at the B'-B' cut line. By cutting out,
It is also possible to adjust the dimensions of the door in accordance with the height and width of the opening, but in the former case, it is necessary to perform some reinforcement at the site to reduce the rigidity of the upper and lower ends of the door. In addition, in the latter case, there is a problem that skill is required to cut the relatively thick vertical frames c and d smoothly.

In addition, since the conventional door body is constituted by front and back panels a, b, vertical frames c, d having a large cross section, and a plurality of horizontal rails e, e ...
There was also a problem that the weight was large and the workability was poor, as well as expensive.

Furthermore, the conventional foldable door, when extending the folded first and second door bodies when closing the opening, puts a finger between the connecting side sides of the first and second door bodies. There is a risk of pinching, especially when a quick stop assisted by the biasing force of a spring is used as a hinge between the first and second doors to ensure the final closing. At the time of the final closing, the second door body is quickly closed in combination with the force for manually pressing the second door body, and there is a risk of pinching a finger. Further, as described above, since the conventional door body is heavy, the impact when a finger is pinched is also large.

This invention was made in view of the above circumstances, and its purpose is to be able to easily change and adjust the height and width dimensions on site, and to perform reinforcement work after cutting separately on site. It aims to provide a foldable door that can increase versatility without requiring the skill of an operator and that can prevent a finger from being caught at the time of closing while being lightweight and inexpensive. is there.

[Means for Solving the Problems] In order to achieve the above object, the folding door of the present invention is provided with a first door which is openably and closably mounted on a frame constituting an opening.
And a second door body which is connected to a free end of the first door body via a hinge so as to be foldable with each other, and the first and second doors are provided. A body, a plurality of cross bars fixed to the back surface of the panel body in parallel with each other except for cutout portions at upper and lower ends of the panel body, and reinforcements secured to upper and lower ends of the back surface of the panel body. It comprises a plate and an edge member having a U-shaped cross section which is mounted at a side end of the panel body so as to sandwich the panel body and the cross rail.

In the present invention, the edge member may be any one as long as it has a U-shaped cross section that sandwiches the panel body and the horizontal rail, but preferably, the panel body insertion grooves are provided symmetrically on both sides of the edge member. In addition, it is preferable that the reinforcing vertical frame portion is integrally formed between the panel body insertion grooves. In addition,
The edge member is not necessarily required to be integral, and may be constituted by, for example, an inner edge member attached to the end surface of the door body, and a makeup / outer edge member attached to the outer surface of the inner edge member. it can. When the edge member is formed of two members in this manner, the adjacent sides of the door body cooperate with the outer surface of the outer and outer edge member to form a semicircular concave groove, and to provide one side. It is desirable to attach a handle member having a C-shaped cross section at a vertically intermediate portion in the concave groove portion of the makeup / outer edge member.

In addition, the folding door of the present invention has a first door body pivotally openably and closably attached to a frame body forming an opening, and is foldable to each other via a hinge at a free end of the first door body. And a second door body connected to the second door body. The connection side edge of the surface of one of the first and second door bodies is provided on the surface of the other panel body. A closing member protruding toward the main body is fixed in a longitudinally extending manner.

In the present invention, the first and second doors may be a composite panel in which an aggregate such as a vertical frame, a horizontal rail, or the like is interposed between the front and back panel bodies, but preferably the first and second doors. A panel body, a plurality of horizontal rails fixed to the back surface of the panel body in parallel with each other leaving cutout portions at the upper and lower ends of the panel body, and a reinforcing plate fixed to the upper and lower ends of the back surface of the panel body And an edge member having a U-shaped cross section which is mounted at a side end of the panel body so as to sandwich the panel body and the cross rail.

In addition, as long as the closing member is fixed to the connecting side portion on the surface of one of the first and second door bodies in a longitudinally extending manner, the entire closing member has the same sectional shape. Although there is no problem, a handle is preferably formed at an intermediate portion in the vertical direction of the closing member. In this case, the handle may be formed by cutting out both sides of the closing member, or may be formed by fixing a separate handle member to the closing member.

[Operation] By configuring as described above, the upper and lower ends and / or side edges of the panel body can be cut off at the site to enable the height and width dimensions to be adjusted. The rigidity is ensured by the reinforcing plate even if the reinforcing work is not separately performed after cutting off the part, and it is easy to work by cutting off the reinforcing plate relatively thinner than the cross rail, and the weight is higher than the conventional one. Is lighter and less expensive. When the width is adjusted by cutting out the side of the panel body, the end of the horizontal rail is cut along with the side of the panel body.

In addition, the first member is fixed to the connecting side portion on the surface of one of the first and second door bodies toward the surface of the other panel body in a longitudinally continuous manner. When the second door body is extended, the gap between the connecting side portions of both door bodies is closed by the closing member.

Furthermore, with the configuration in which the handle portion is formed at an intermediate portion in the vertical direction of the closing member, the handle portion can be positioned at the intermediate portion in the vertical direction even when the folding door is inverted.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing a mounted state of the first embodiment of the folding door of the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG.

The folding door according to the present invention includes a gate-shaped frame body 14 having a pair of vertical frame members 10 and an upper frame member 12 for connecting the upper ends of the vertical frame members 10 to each other, and an upper frame. A first door 20 pivotally connected to the frame 14 via a pivot pin 18 provided on the body 12 and the flooring 16 so as to be openable and closable, and a hinge 22 attached to a free end of the first door 20 And a second door 24 that is connected to each other in a foldable manner.

As shown in FIGS. 3 and 4, the first and second doors 24 are provided with a panel 30 on the front side and a cutout 32 at upper and lower ends of the panel 30. A plurality (in this embodiment, 5

From the upper part of the horizontal rail 34a on the back surface of the panel body 30, the panel body 3
The reinforcing plate 36 is fixed to the upper end of the panel body 30 and from the lower part of the horizontal bar 34e to the lower end of the panel body 30, and is mounted to sandwich the panel body 30 and the horizontal bar 34 at both side ends of the panel body 30. And an edge member 40 having a U-shaped cross section formed of, for example, an extruded shape member made of aluminum.

As shown in FIGS. 5 and 6, the edge member 40 is formed by bending sandwiching pieces 43 on both sides of an edge member main body 42 having a reinforcing rib 41 at the center. The panel body insertion grooves 44, 44 are symmetrical to each other, and a vertical frame portion 45 for reinforcement protruding inward is provided between the panel body insertion grooves 44, 44. Therefore, since the edge member 40 is symmetrical left and right, the panel body 30 and the horizontal beam 34 are held between the holding pieces 43, 43 with the panel body 30 inserted into the panel body insertion groove 44 on both the left and right sides. And can be fixed. In this case, the edge member 40 is bonded to both sides of the first and second door bodies 20 and 24 with an adhesive, but the reinforcing rib provided at the center of the reinforcing vertical frame portion 45 is provided.
Due to the presence of the 41 grooves 41a, the adhesiveness is improved.

When the edge member 40 is sandwiched between the panel body 30 and the horizontal rail 34, the ends of the panel body 30 and the horizontal rail 34 are positioned so that the holding pieces 43 located on the front and back sides are flush with the panel body 30 and the horizontal rail 34. The portion may be provided with a notch 35 corresponding to the thickness of the holding piece 43 (the drawing shows a case where the notch 35 is provided only in the horizontal rail 34).

Also, hinges 22 are attached to the free-side end of the first door body 20 and the rear-side end of the horizontal rails 34a, 34c, 34e at one end of the second door body 24, and the first and second hinges are provided. The doors 20, 24 are foldable from each other.

In addition, the horizontal rail 34 is arranged at the top, bottom, and central part 34a,
Although those having a larger vertical dimension and a larger thickness dimension than those of the other ones 34c and 34e are used, the vertical dimension and the thickness dimension of all the horizontal rails 34 may be the same.

A blocking member 50 protruding toward the surface of the panel body 30 of the first door body 20 is fixed to an end portion on the surface side of the second door body 24 at a connection side edge of the surface of the panel body 30 in a longitudinally extending manner. Have been. Also, in the middle part in the vertical direction of the closing member 50,
A handle portion 52 having a T-shaped cross section is formed, which can be hooked by hand by notching leaving a central portion in the width direction.

In addition, the configuration of the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the case where the frame body 14 is a gate type including the pair of vertical frame members 10 and the upper frame member 12 has been described. Similarly, the first door body 20 can be pivotally attached to the rectangular frame body 14 to which the lower frame member is added so that the first door body 20 can be opened and closed. Furthermore, the first and second door bodies 20 and 24 can be rotatably pivoted over the entire area from the floor surface to the ceiling surface. With this configuration, the number of members can be reduced, Particularly, it is preferable in that a narrow indoor space can be effectively used.

Further, the first door body 20 is pivotally connected to the opening via the pivot pin 18 so as to be openable and closable, but the first door body 20 is connected to one of the vertical frame members 10 via a hinge (not shown). Needless to say, it may be pivotally attached so that it can be opened and closed.

Further, in the above embodiment, the closing member 50 is fixed to the front end of the second door 24, but the second door 24 is replaced with the second end at the front end of the first door 20. The closing member 50 may be fixed so as to protrude toward the surface of the panel body 30 of the door body 24.
Further, the handle portion 52 is formed by piercing the closing member 50 while leaving a central portion in the width direction.
May be fixed to the surface.

Next, an example of an assembling procedure of the folding door of the present invention and an assembling procedure to the opening will be described.

In advance in a factory or the like, a panel is prepared by fixing a plurality of horizontal rails 34 in parallel with each other while leaving the cutout portions 32 at the upper and lower ends on the back surface of the panel body 30, and according to the height and / or width dimensions at the site. Panel body 30 along line AA and line BB in FIG.
And the reinforcing plate 36, or the panel body 30, the reinforcing plate 36 and the cross rail 34 are cut. In this case, the reinforcing plate 36 may be fixed to the back surface of the panel body 30 after cutting the cutout portion 32 of the panel body 30. Next, the edge members 40 are mounted on both sides of the panel to form the first and second doors 20 and 24. A closing member protruding toward the surface of the panel body 30 of the first door body 20 at the connection side edge on the surface of the second door body 24

By attaching the hinges 22 to the back side ends of the horizontal rails 20 and 24 with screws or the like, the folding door is assembled.

Further, in order to assemble the folding door of the present invention to the frame body 14 forming the opening at the site, the first door body is connected via the pivot pins 18 provided on the upper frame member 12 and the floor member 16. What is necessary is just to pivotally connect 20 to the frame 14 so that it can be opened and closed.

At this time, even if the height or width of the frame body 14 is changed due to a design change or the like after assembling the folding door, similar to the above, the AA line and the BB line in FIG. Panel body 30 and reinforcing plate 36, or panel body 30 and reinforcing plate 36
In addition, by cutting off the horizontal rail 34, site adjustment can be easily performed while securing rigidity. Moreover, there is no need to perform any reinforcement on site as in the prior art, and there is no need for skill because a relatively thick vertical frame is not cut off smoothly.

Therefore, in the folding door of the present invention, the height of the first and second door bodies 20 and 24 is not fixed to the height of the vertical frame as in the conventional case, so that the height of the opening is not increased. The height dimensions can be adjusted on site without preparing a door body having a different height dimension for each of the different height dimensions, and the versatility of the door body for each opening is significantly improved.

Further, while the conventional door body is constituted by front and back panels, a vertical frame having a large cross section, and a plurality of horizontal rails, the door body of the present invention does not use the rear panel and the vertical frame, and is lightweight and inexpensive. In spite of the configuration, sufficient rigidity can be obtained by the reinforcing plate 36, the edge member 40, and the vertical frame 45 for reinforcement.

Further, since the handle 52 is located at the middle part of the closing member 50 in the vertical direction, even if the folding door is installed upside down, it is located at the middle part in the vertical direction, and the opening of the folding door is inverted. Can be dealt with in place of either right-handed or left-handed opening, and the versatility can be increased.

The notch 35 of the horizontal rail 34 may be cut out before the edge member 40 is attached, or may be cut out in advance.
The closing member 50 may be fixed before connecting the first and second door bodies 20 and 24, or may be fixed after connecting.

Next, an example of the opening / closing operation of the folding door of the present invention configured as described above will be described.

First, in order to open the opening closed by the first and second door bodies 20 and 24, the handle member 26 attached to the second door body 24 is gripped and attracted, thereby opening the second door body 24. The door body 24 is folded with respect to the first door body 20 and the first door body 20 is folded.
Is rotated forward with respect to the frame 14. At this time, the movement trajectory of the first and second door bodies 20, 24 is narrow as described above.

On the other hand, the opened openings are connected to the first and second door bodies 20, 24.
In order to close the first door body 20, the first door body 20 is rotated rearward with respect to the frame body 14 by hooking and pushing a handle 52 of the closing member 50 fixed to the second door body 24. Second with
Is performed by extending the door body 24 with respect to the first door body 20. At this time, the gap between the connecting side portions of the first and second door bodies 20 and 24 narrows according to the extension of the first and second door bodies 20 and 24, but the panel body 30 of the second door body 24 Since the closing member 50 fixed to the surface of the second member closes the gap, it is possible to prevent the finger from being pinched too much.

In the above embodiment, the case where the edge member 40 is formed of an extruded shape member made of an aluminum alloy has been described. However, the edge member 40 is not necessarily required to be formed integrally, for example, as shown in FIG. An inner edge member 46 formed of a steel press profile mounted on the end face of the first door body 20, and mounted on the outer surface of the inner edge member 46 and the panel body 30 and the horizontal It can also be configured with a makeup / outer edge member 47 mounted with the bar 34 sandwiched. In this case, the inner edge member 46 is formed in a hat shape in cross section, and is fixed to the end face of the cross rail 34 with fixing screws 48, 48 on the flange portions 46a, 46a on both sides, and the central protruding portion 46b
Is fixed with a screw 49 with a shoulder. And
As shown in FIG. 8, between the shoulder portion 49a of the shoulder screw 49 and the head portion 49b, for example, a narrow overflow opening 47a provided on the mounting side end surface of the wooden decorative and outer edge member 47 is located. By fitting the dovetail groove 47b so that
A cosmetic and outer edge member 47 can be attached. In the case where the edge member 40 is formed of the two members, the inner edge member 46 and the decorative / outer edge member 47 in this manner, the decorative members on the adjacent sides of the first and second door bodies 20 and 24 are provided. Recessed grooves 47c, 47c cooperating with the outer surfaces of the outer edge members 47, 47 to form a semicircular arc.
It is preferable to attach a handle member 54 having a C-shaped cross section to an intermediate portion in the vertical direction of the concave groove 47c of one of the decorative and outer edge members 47 (see FIGS. 7 and 9). By attaching the handle member 54 in this manner, the hand is always placed on the handle member 54 when the door is opened and closed, so that the finger is not pinched too much.

Note that the inner edge member 46 does not necessarily need to have a hat-shaped cross section, and may have a flat plate shape.
