Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a filled panel, and more particularly to a filled panel formed by filling an outer shell with an expandable filler such as a foamed resin.

[0002]

[Prior art]

 Today, filler-filled panels are frequently used for various types of wall materials and doors in buildings. This type of panel is generally formed by filling a filler inside a shell formed of a metal or synthetic resin plate. The filler in this case is selected according to the use of the panel or the like, but a foamed synthetic resin, for example, a foamed urethane or the like, is often used. In manufacturing a panel using such a filler, usually, the outer shell is pre-assembled so as to form a substantially closed flat space, and then the filler is injected from an inlet formed in the outer shell. And expands inside the outer shell.

[0003] Therefore, it is necessary to tightly seal the joints of the outer shells constituting such a filler-containing panel so that the filler expanding inside does not leak. 5 and 6 show examples of sealing means in a conventional panel with a filler. In the panel 1 shown in FIG. 5, the outer shell 3 is formed by joining the front plate 5 and the back plate 7, that is, the portion where the side surface 5 a of the front plate 5 and the side surface 7 a of the back plate 7 overlap. Then, a paper tape 9 is attached from the inside to seal. In the panel 11 shown in FIG. 6, a packing 13 made of a synthetic resin is attached to the side surface 5a of the front plate 5, and a groove 13a extending parallel to the side surface 5a is formed in the packing 13. By inserting the side surface portion 7a of the back plate 7 into the groove 13a, the joint between the front plate 5 and the back plate 7 is sealed.

[0004]

[Problems to be solved by the invention]

 However, these conventional sealing means require special members such as the paper tape 9 and the packing 13 and special man-hours for attaching these members. In particular, when the packing 13 is used, the production of the packing 13 alone requires a considerable cost, and when the paper tape 9 is used, the work of attaching the paper tape 9 becomes extremely troublesome.

The present invention has been made in view of the above-described conventional problems, and has a filler-filled panel that can reliably seal the joint of the outer shell without using a special sealing member. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the filler-filled panel of the present invention forms an outer shell by assembling at least two plate-shaped outer shells with each other, and fills the outer shell with an expandable synthetic resin filler. A panel comprising a filler, wherein at least one of the two outer shell materials is integrally formed with a side surface constituting a side surface of the outer shell, and the side surface and the other outer shell material are integrally formed. When these two outer shell materials are assembled, a seal portion that contacts each other is formed integrally with the outer shell material, and this seal portion is formed on a surface parallel to the mounting direction of the two outer shell materials. It is provided with a first seal piece in contact with the first seal piece and a second seal piece in contact with the first seal piece on a curved surface.

In this panel, when the two outer shell materials are assembled, the mating portion is bent into a substantially key shape by the contact between the first seal piece and the second seal piece of the seal portion. A part is formed. Therefore, since the mating portion, particularly the mating portion of the second seal pieces, is positioned so as to protrude into the space of the outer shell, the seal pieces are pressed against each other by the expansion pressure of the filler filled in the outer shell. Be tightly sealed. Even if the filler material enters the joint, it is not easy for the filler to completely pass through the joint because the joint is bent in a key shape. Therefore, there is no possibility that the invading filler material leaks out of the seal portion.

According to a second aspect of the present invention, in the filler-filled panel according to the first aspect, one of the seal portions has a third seal piece parallel to the first seal piece so that the other seal portion has the third seal piece. Opened in a U-shape with respect to the seal part, and the distance between the first seal piece and the third seal piece is made equal to the width of the second seal piece in the other seal part. It is. With this configuration, the other seal portion fits tightly into the one seal portion, so that the contact between the first seal piece and the second seal piece is stably maintained, and the second seal portion is stably held. Since the tip of the second seal piece abuts the third seal piece in the one seal part to close the entrance of the mating part, the sealing state is more reliable.

[0009]

[Embodiment of the invention]

 Hereinafter, the panel 21 according to the embodiment of the present invention will be described with reference to the drawings. Reference numeral 23 denotes a folding door-type closet door. The closet door 23 is formed by connecting two panels 21 via a hinge 24 so as to be freely foldable.

The panel 21 is composed of an outer shell 25 assembled in a vertically elongated flat box shape and a filler 27 filled inside the outer shell 25, and the outer shell 25 serves as an outer shell material. The upper and lower two connecting plates 33 are formed by assembling the front plate 29 and the back plate 31 made of a color steel plate, and the filler 27 is made of urethane foam.

The front plate 29 includes a vertically long rectangular front portion 35, upper and lower side portions 37 and left and right side portions 39 formed by bending four side ends of the front portion 35 inward. Become. The upper and lower side portions 37 have a strip shape elongated in the left and right directions simply bent at a right angle to the front portion 35, and have a width of about one third of the thickness of the outer shell 25. A semicircular notch 37a is formed in the middle of the side edge.

The left and right side portions 39 are composed of a vertically long side plate-shaped side main portion 41 and a seal portion 43 located inside the front end portion of the side main portion 41. The side surface main portion 41 is a portion constituting the left and right side surfaces of the outer shell 25 itself. Therefore, the front and rear width thereof is about three times the width of the upper and lower side surface portions 37, and the portion connected to the front surface portion 35 is It is bent in a substantially arc shape. The seal portion 43 is bent so as to form a U-shape that opens rearward when viewed in a horizontal section (see FIG. 3). That is, the seal portion 43 is folded at a right angle to the first seal piece 43a and parallel to the front portion 35 at the end of the side main portion 41 so as to be folded from the inside. A second seal piece 43b and a third seal piece 43c bent at right angles (parallel to the first seal piece 43a) with respect to the second seal piece 43b.

Similarly to the front plate 29, the back plate 31 has a vertically-elongated rear surface 45 and upper and lower side surfaces 47 and 47 formed by bending four side ends of the rear surface 45 inward. And left and right seal portions 49. The rear part 45 has substantially the same size as the front part 35. The upper and lower side surfaces 47 of the back plate 31 also have a long strip shape in the left and right direction having substantially the same size as the upper and lower side surfaces 37 of the front plate 29, and have a semicircular shape in the middle of the side edge. A notch 47a is formed, and small rivet holes 47b are formed near both ends.

When viewed in a horizontal cross section (see FIG. 3), the seal portion 49 is bent so as to form a substantially L-shape facing each other. That is, the seal portion 49 includes a first seal piece 49a bent at a right angle to the back surface portion 45, and a second seal material bent at a right angle to the first seal piece 49a and parallel to the back surface portion 45. Piece 49b. The left and right width of the second seal piece 49b is substantially equal to the distance between the first seal piece 43a and the second seal piece 43c in the seal portion 43 of the front plate 29.

The connecting plate 33 is long in the left-right direction and is formed to have a substantially U-shape when viewed from the longitudinal direction. The intermediate piece 51 of the connecting plate 33 is formed with a circular filling port 51a at the center thereof and small rivet holes 51b at positions near both ends, and a small air vent is provided between the filling port 51a and the rivet hole 51b. A hole 51c is formed. A sponge (not shown) is attached to the air vent hole 51c from the inside, and a valve seat 53 is attached to the filling port 51a from the inside so as to close the filling port 51a. The valve seat 53 has flexibility, and only one end thereof is fixed to the connecting plate 33. The valve seat 53 bends as shown by a two-dot chain line in FIG. 4 so as to open the filling port 51a. I have.

The outer shell 25 is assembled as follows. First, one end of the intermediate piece 51 of the connecting plate 33 is placed on the upper and lower side surfaces 37 of the front plate 29 from inside, and in this state, the connecting plate 33 and the side surfaces 37 are fixed to each other. This fixing is performed by spot welding or the like. Next, the left and right seal portions 49 of the back plate 31 are abutted against the seal portions 43 of the front plate 29 while the upper and lower side portions 47 of the back plate 31 are overlapped with the other end of the intermediate piece 51 of the connecting plate 33. As a result, the rivet holes 47b of the back plate 31 and the rivet holes 51b of the connecting plate 33 overlap, and the rivets 55 are driven into these holes. Thus, the front plate 29 and the back plate 31 are integrally connected to each other via the connection plate 33, whereby the flat box-shaped outer shell 25 having an internal space is formed. Then, a substantially circular hole is formed by the notches 37a and 47a formed in the upper side surface portions 37 and 47, and the filling port 51a is located at a position coinciding with the hole. The air vent hole 51c is located between the upper side surface portions 37 and 47 and is exposed.

The upper and lower side surfaces of the outer shell 25 are closed by the connecting plate 33, and the left and right side surfaces are closed by the left and right seal portions 49 of the back plate 31 abutting against the seal portions 43 of the front plate 29. That is, as shown in FIG. 3, the first seal pieces 49a and 43a overlap the second seal pieces 49b and 43b, and the second seal piece on the back plate 31 side. The leading edge of 49b comes into contact with the third seal piece 43c, and thereby, the joint at the right and left sides of the front plate 29 and the back plate 31 is sealed.

Therefore, the seal portion 49 of the back plate 31 fits in the U-shaped seal portion 43 of the front plate 29, so that the contact between the first seal pieces 43a and 49a and the second seal piece 43b and 49b are stably held in contact with each other, and the tip of the second seal piece 49b in the seal portion 49 on the back plate 31 is in contact with the third seal piece 43c in the seal portion 43 of the front plate 31. The contact portion closes the entrance of the joint portion between the seal portions, thereby further enhancing the sealing effect.

After the outer shell 25 is formed in this way, a filler nozzle is inserted into the filling port 51 a to fill the outer shell 25 with the filler 27. When performing this filling, bending deformation is prevented by pressing the outer shell 25 from both sides in the thickness direction. When the filling nozzle is inserted through the filling port 51a, the valve sheet 53 is bent to open the filling port 51a. When the filling nozzle is pulled out from this state, the valve sheet 53 expands the filled filler 27. The filling port 51a is firmly closed by the pressure.

The filler 27 filled in the outer shell 25 expands while gradually foaming and reaches every corner inside the outer shell 25, and the expansion pressure of the filler 27 is increased by the front plate 29, the back plate 31, It acts so as to press each part of the connecting plate 33 outward. In this case, at the joints on the right and left sides of the front plate 29 and the back plate 31, the expansion pressure of the filler 27 causes the second seal pieces 43b and 49b to press against each other, and the first seal piece 43b on the back plate 31 side. Since the sealing piece 49a acts to press against the first sealing piece 43a of the front plate 29, this press-fitting surely prevents the leakage of the filler material 27 at the joint.

[0021] Even if the filling material 27 slightly invades between the seal portion 49 and the seal portion 43 due to the insufficient pressure bonding described above, the seal portions 49 and 43 come into contact with each other. Since the parts that come into contact with each other are bent in a key shape, there is no possibility that the filler 27 leaks out. By filling the filler 27, the air inside the outer shell 25 goes out of the air vent hole 51c through a sponge (not shown).

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Is also included in the present invention. For example, in the embodiment, the seal according to the present invention is applied only to two of the four side surfaces of the outer shell which are located on opposite sides, but the present invention is applied to all of the four side surfaces. A seal according to the invention may be provided. In the embodiment, the present invention is applied to a panel of a closet door. It can be widely applied as a panel with a simple filler.

[0023]

[Effect of the invention]

 As described above, in the filled panel of the present invention, when the two outer shell materials are assembled, the contact between the first seal piece and the second seal piece of the seal portion causes A joining portion bent in a substantially key shape is formed. Therefore, since the mating portion, particularly the mating portion of the second seal pieces, is located so as to protrude into the space of the outer shell, the seal pieces are pressed against each other by the expansion pressure of the filler filled in the outer shell. And seal tightly. Even if the filler material enters the joint, it is not easy for the filler to completely pass through the joint because the joint is bent in a key shape. Therefore, there is no possibility that the invading filler material leaks out of the seal portion.

According to the second aspect of the present invention, the other seal portion fits into the one seal portion, so that the contact between the first seal pieces and the contact between the second seal pieces are stably maintained. At the same time, the tip of the second seal piece in the other seal portion abuts the third seal piece in the one seal portion to close the entrance of the mating portion, so that the sealing state is more reliable. It becomes something.
