Description

  The present invention relates to a door panel used for a hinged door, a folding door, a sliding door, or the like, and in particular, a door panel including a door frame composed of a vertical frame material and a horizontal frame material, and a plate-like surface material joined to the door frame. About.

  A structure in which a plate-like surface material is joined to a door frame composed of a vertical frame material and a horizontal frame material is known as a “flash structure”, and the “flash structure” can be easily reduced in weight. It is widely used in door panels using wooden materials because it is less crazy.

  However, door panels using wood materials are susceptible to the effects of temperature and humidity, so even if the “flash structure” is adopted, the “warping” of the door panel due to these effects cannot be completely suppressed. In particular, in the cold season, the “warping” of the door panel is increased due to the temperature difference or humidity difference between both sides of the door panel, which may impede the function of the door panel. For example, in the door panel attached to the entrance of the room, the temperature difference or humidity difference between the indoor side surface heated by the indoor heating and the outdoor side surface cooled by the outside air becomes enormous, The “warping” of the door panel becomes remarkably large, and there is a possibility that the door panel cannot be opened and closed, or that a draft is blown from the periphery of the door panel.

Therefore, various techniques for preventing “warping” of the door panel have been developed, and examples thereof are disclosed in Patent Documents 1 and 2. That is, Patent Document 1 discloses “a furniture door in which a substantially U-shaped bracket is disposed in a long groove formed in a vertical frame”. Discloses a wooden door incorporating a perforated metal plate.
Japanese Patent Laid-Open No. 5-1491 JP-A-9-13818 JP-A-9-203278

  According to the prior art (Patent Documents 1 and 2), a furniture door or a wooden door is reinforced by a substantially U-shaped bracket or a perforated metal plate (hereinafter collectively referred to as “reinforcing material”). Therefore, the “warp” problem can be solved.

  However, when two members arranged on both sides of the reinforcing material are joined with a tucker, the tucker must be driven away from the reinforcing material, so the “reinforcing strength” by the reinforcing material and the “joining strength by the tucker” It was difficult to satisfy both.

  In other words, when giving priority to “reinforcement strength”, it is necessary to increase the “thickness” of the reinforcing material. However, if the “thickness” of the reinforcing material is increased, an approximately U-shaped tucker will straddle them. Can not be. Therefore, the location where the tucker can be used is limited to a very narrow range, and the “joining strength” cannot be obtained sufficiently. On the other hand, when giving priority to “joining strength”, it is necessary to drive a substantially U-shaped tucker so as to straddle the reinforcing material, but for that purpose, the “thickness” of the reinforcing material must be reduced, “Reinforcing strength” is impaired.

  As a means for solving this problem, it is conceivable to form a “notch” in the reinforcing material in advance and drive a tucker through this “notch” (see Patent Document 3). Not only is the processing of “notches” troublesome, but the strength of the reinforcing material is impaired by the “notches”, so that there is a problem that “warping” cannot be sufficiently suppressed especially for long panel panels of 8 or more. there were.

  Therefore, a main problem of the present invention is to provide a door panel that can sufficiently ensure “joining strength” by a tucker without causing an increase in “working effort” and a decrease in “reinforcing strength”.

  According to the first aspect of the present invention, “a door frame 12 constituted by joining at least two vertical frame members 18 with a horizontal frame member 20, and a plate-like surface material 16 joined to the door frame 12. In the door panel 10, a groove 22 having a substantially rectangular cross section extending in the vertical direction is formed on a side surface of the vertical frame member 18 facing the horizontal frame member 20, and in the groove 22, A band plate-shaped fixing plate portion 24 attached to the bottom surface 22a of the groove 22, and a side wall plate portion 26 formed in a substantially circular arc shape continuously at both ends in the width direction of the fixing plate portion 24, (42) , 44, 48, 50 are accommodated, and the vertical frame member 18 and the horizontal frame member 20 are arranged on the surface side of the door frame 12 or The reinforcing material 14, 34, 36, 3 is provided on at least one of the back side. , Characterized in that it is connected by Tucker 32 driven so as to straddle the 40, a door panel 10 '.

  In the present invention, since the rod-shaped reinforcing members 14, 34, 36, 38, 40 having the side wall plate portions 26, (42), 44, 48, 50 having a substantially arc-shaped cross section are used, the reinforcing members 14, 34, Even if the “thickness” of 36, 38, 40 is reduced, sufficient “reinforcing strength” can be obtained in all directions. That is, in the side wall plate portions 26, (42), 44, 48, and 50 having a substantially arc-shaped cross section, there is no “corner portion” that the side wall plate portion having a substantially U-shaped cross section has. No “bending” or “bending” occurs, and the “thickness” of the reinforcing members 14, 34, 36, 38, 40 can be reduced without impairing the “reinforcing strength”. Therefore, when the vertical frame member 18 and the horizontal frame member 20 are connected by the tucker 32, the reinforcing members 14, 34, 36, 38, 40 are straddled on at least one of the front side or the back side of the door frame 12. Thus, the tucker 32 can be driven in and the “joining strength” by the tucker 32 can be sufficiently secured.

  According to the second aspect of the invention, “a door frame 56 formed by joining at least two vertical frame members 58 with a horizontal frame member 60, and a plate-like surface material 16 bonded to the door frame 56. In the door panel 54, the vertical frame member 58 is formed by joining side surfaces of a plurality of rod-like vertical frame members 58a and 58b, and the two vertical frames joined together. A groove 62 having a substantially rectangular cross section extending in the vertical direction is formed on the other side surface of either one of the constituent members 58a and 58b. A band attached to the bottom surface of the groove 62 is formed in the groove 62. A rod-like plate having a plate-like fixing plate portion 24 and side wall plate portions 26, (42), 44, 48, 50 formed in a substantially arc shape in cross section continuously at both ends in the width direction of the fixing plate portion 24. Reinforcing materials 14, 34, 36, 38, 40 are accommodated The two vertical frame members 58a and 58b to be joined to each other are arranged to straddle the reinforcing members 14, 34, 36, 38, and 40 on at least one of the front side and the back side of the door frame 56. It is a door panel 54 "characterized in that it is connected by a tucker 32 driven in.

  In the present invention, the reinforcing members 14, 34, 36, 38, 40 are accommodated in the grooves 62 formed on the side surfaces of the vertical frame constituent members 58a, 58b, and the two vertical frame constituent members 58a, 58b are attached to the tucker 32. The “configuration of the reinforcing members 14, 34, 36, 38, 40 itself” and “the positional relationship between the reinforcing members 14, 34, 36, 38, 40 and the tucker 32” are claimed in the claims. This is the same as the invention described in Item 1.

  According to the first and second aspects of the invention, the “joining strength” by the tucker 32 can be sufficiently ensured without causing a decrease in the “reinforcing strength” by the reinforcing members 14, 34, 36, 38, and 40. Further, since it is not necessary to form “notches” (see Patent Document 3) for passing the tucker 32 in the reinforcing members 14, 34, 36, 38, 40, the reinforcing members 14, 34, 36, 38, 40 Processing is easy, and there is no increase in “processing time”.

  FIG. 1 is a partial sectional front view showing a door panel 10 to which the present invention is applied, FIG. 2 is a partial sectional view showing a section when the door panel 10 is cut in a horizontal plane, and FIG. It is a fragmentary perspective view which shows the door frame 12 used for the door panel 10. FIG.

  The door panel 10 (FIGS. 1 and 2) is a plate-like member that closes the opening in a “folding door”, “folding door”, or “sliding door” that opens and closes between the rooms of a house or an opening for storage. A frame 12, a reinforcing material 14, and a plate-like surface material 16 bonded to both front and back surfaces of the door frame 12 are provided.

  The door frame 12 is a frame-shaped member formed by framing at least two (two in this embodiment) vertical frame members 18 and at least two (four in this embodiment) horizontal frame members 20. Thus, the door frame 12 becomes a “core” and the entire shape of the door panel 10 is maintained.

  The vertical frame member 18 (FIGS. 1 to 3) is a rod-shaped member having a substantially rectangular cross section that constitutes the widthwise end of the door frame 12, and the side surface of the vertical frame member 18 that faces the horizontal frame member 20, that is, the door frame 12. A groove 22 for accommodating the reinforcing material 14 is formed on the side surface located on the inner side so as to extend in the longitudinal direction, that is, the longitudinal direction.

  As shown in FIG. 2, the groove 22 is a concave groove having a substantially square cross section, and the “width” of the groove 22 is set sufficiently larger than the “depth”. As shown in FIG. 3, the longitudinal end portion of the groove 22 may be opened on the end surface of the vertical frame member 18 or may be closed before the end surface of the vertical frame member 18 (not shown). .

  The material of the vertical frame member 18 is not particularly limited, but it is desirable to use a woody material such as LVL (parallel plywood), plywood, laminated material, or solid material in terms of easy processing.

  The reinforcing member 14 is a rod-shaped member made of metal (steel, stainless steel, aluminum, etc.), alloy, plastic, or the like, and is disposed in parallel with the bottom surface 22a of the groove 22 as shown in FIG. A fixed plate portion 24 having a strip plate shape to be attached, and a side wall plate portion 26 formed in a substantially arc shape in cross section continuously at both ends in the width direction of the fixed plate portion 24. The side wall plate portion 26 is formed in a substantially C-shaped cross section that protrudes outward in the thickness direction of the door panel 10, and the interval D between the front end portions of the two side wall plate portions 26 is the head 28 a of the fixing screw 28. Is set larger than the diameter d. A through hole 30 through which the fixing screw 28 is inserted is formed in the center portion in the width direction of the fixing plate portion 24.

  When the side wall plate portion 26 has “spring elasticity”, it is desirable to set the “maximum width” of the side wall plate portion 26, that is, the “maximum thickness” of the reinforcing member 14 to be larger than the depth of the groove 22. With this setting, the reinforcing material 14 can be brought into contact with both the “bottom surface 22 a of the groove 22” and the “end surface of the horizontal frame material 20”. Can be reliably prevented.

  The horizontal frame member 20 is a rod-shaped member having a substantially rectangular cross section, and the “thickness” of the horizontal frame member 20 in the thickness direction of the door panel 10 is set to be the same as the “thickness” of the vertical frame member 18. . In the present embodiment, four horizontal frame members 20 are used, and two of the horizontal frame members 20 form the longitudinal ends of the door frame 12, and the remaining two horizontal frame members 20. The door frame 12 is reinforced. One end of each horizontal frame member 20 is in contact with the side surface of one vertical frame member 18, and the other end is in contact with the side surface of the other vertical frame member 18. The frame member 20 is connected to the frame member 20 by a tucker 32 that is driven so as to straddle the reinforcing member 14 on at least one of the front side or the back side of the door frame 12.

  The material of the vertical frame member 18 is not particularly limited, but it is desirable to use a woody material such as LVL (parallel plywood), plywood, laminated material, or solid material in terms of easy processing.

  As shown in FIGS. 2 and 3, the tucker 32 includes a pin-shaped first driving portion 32 a driven into the vertical frame member 18, a pin-shaped second driving portion 32 b driven into the horizontal frame member 20, and a first The connecting portion 32c that connects the driving portion 32a and the second driving portion 32b is formed in a substantially U shape.

  The surface material 16 is a plate material constituting both front and back surfaces of the door panel 10, and specifically, a wood material such as plywood, medium density fiber board or high density fiber board, and a synthetic resin decorative sheet or makeup on these surfaces. A material to which paper or a veneer is attached is used as the surface material 16.

  When assembling the door frame 12, the reinforcing material 14 is accommodated in the groove 22 formed on the side surface of the vertical frame material 18, and the fixing screw 28 is inserted into the through hole 30 formed in the fixing plate portion 24 of the reinforcing material 14. The fixing screw 28 is screwed into the bottom surface 22 a of the groove 22. Then, the head portion 28 a of the fixing screw 28 is locked to the surface of the fixing plate portion 24 through between the front end portions of the side wall plate portion 26, and the fixing plate portion 24 is fixed to the bottom surface 22 a of the groove 22 by the head portion 28 a.

  Subsequently, the horizontal frame member 20 is disposed between the two vertical frame members 18, one end of the horizontal frame member 20 is brought into contact with the side surface of one vertical frame member 18, and the other end is connected to the other vertical frame member 18. It is made to contact 18 side surfaces. Then, the vertical frame member 18 and the horizontal frame member 20 are connected to each other by driving the tucker 32 so as to straddle the reinforcing member 14. In order to ensure the joining of the vertical frame member 18 and the horizontal frame member 20, it is desirable to apply an adhesive (such as a vinyl acetate adhesive) to these joint surfaces.

  When the door frame 12 is completed, the surface material 16 is bonded to both the front and back surfaces of the door frame 12 using an adhesive or a fixing screw (not shown). In addition, before joining the surface material 16, you may make it arrange | position a soundproof material or a heat insulating material in the inner space of the door frame 12. FIG.

  According to the present embodiment, the strength of the reinforcing member 14 can be increased by the two side wall plate portions 26 having a substantially arc-shaped cross section. Therefore, the “thickness” of the reinforcing member 14 is reduced while ensuring the “reinforcing strength”. be able to. Therefore, when the vertical frame member 18 and the horizontal frame member 20 are connected by the tucker 32, the tucker 32 can be driven so as to straddle the reinforcing member 14 on at least one of the front side or the back side of the door frame 12. In addition, the “joining strength” by the tucker 32 can be sufficiently ensured without impairing the “reinforcing strength” by the reinforcing material 14.

  Further, in the reinforcing member 14, the end portions of the two side wall plate portions 26 are separated from each other, and an adhesive (not shown) can be filled into the inside of the reinforcing member 14 between them. 14 and the horizontal frame member 20 can be firmly integrated through an adhesive.

  In the above-described reinforcing material 14, the side wall plate portion 26 is formed in a substantially C-shaped cross section that protrudes outward in the thickness direction of the door panel 10, and the distance between the tip portions of the two side wall plate portions 26. D is set to be larger than the diameter d of the head portion 28a of the fixing screw 28, but the side wall plate portion 26 only needs to have a substantially arcuate cross section, and its specific configuration is shown in FIGS. The reinforcing members 34, 36, 38, and 40 shown may be appropriately changed.

  The reinforcing member 34 shown in FIG. 4 has a fixed plate portion 24 and a cylindrical tube portion 42 formed continuously at both ends in the width direction of the fixed plate portion 24, and a part of the tube portion 42. Is a “side wall plate portion” having a substantially arc-shaped cross section that protrudes outward in the thickness direction of the door panel 10. The shortest distance D between the two cylindrical portions 42 is set to be larger than the diameter d of the head portion 28a in the fixing screw 28. Therefore, when the fixing screw 28 is inserted into the through hole 30 formed in the fixing plate portion 24 and this fixing screw 28 is screwed into the bottom surface 22 a of the groove 22, the head portion 28 a of the fixing screw 28 is located between the two cylindrical portions 42. And is fixed to the surface of the fixing plate 24.

  The reinforcing member 36 shown in FIG. 5 has a fixed plate portion 24 and side wall plate portions 44 formed in a substantially arc shape in cross section continuously at both ends in the width direction of the fixed plate portion 24. The side wall plate portion 44 is formed in a substantially C-shaped cross section that protrudes outward in the thickness direction of the door panel 10, and the distance D between the front end portions of the two side wall plate portions 44 is that of the head 46 a of the fixing screw 46. It is set smaller than the diameter d1 and larger than the diameter d2 of the screw portion 46b. Therefore, when the fixing screw 46 is inserted into the through-hole 30 formed in the fixing plate portion 24 and this fixing screw 46 is screwed into the bottom surface 22 a of the groove 22, the head portion 46 a of the fixing screw 46 is formed between the two side wall plate portions 44. Locked to the tip.

  In the reinforcing member 36, the heads 46a of the fixing screws 46 are locked to the tip portions of the two side wall plate portions 44. Therefore, there is no limitation on the types of fixing screws 46 that can be applied. Can be used.

  The reinforcing member 38 shown in FIG. 6 has a configuration in which the reinforcing member 14 shown in FIG. That is, the reinforcing member 38 includes a fixed plate portion 24 that is spaced apart from the bottom surface 22 a of the groove 22, and a side wall plate portion 48 that is formed in a substantially arcuate cross section continuously at both ends in the width direction of the fixed plate portion 24. And have. The side wall plate portion 48 is formed in a substantially C-shaped cross section that protrudes outward in the thickness direction of the door panel 10, and the front end portion of the side wall plate portion 48 is in contact with the bottom surface 22 a of the groove 22. The fixing plate part 24 is formed with a through hole 30 through which the fixing screw 28 is inserted.

  The reinforcing member 40 shown in FIG. 7 includes a fixed plate portion 24 that is spaced apart from the bottom surface 22 a of the groove 22, and a side wall plate that is formed in a substantially arcuate cross section continuously at both ends in the width direction of the fixed plate portion 24.
