[0003]

However, in such a door, the door plate is suspended,
In order to be able to adjust the installation in the left and right direction, the door plate is supported only by the pivot hinges provided on the upper and lower ends of the door plate, and the door plate is supported in the vertical center region of the door plate. However, there is an inconvenience that the warp deformation that maximizes the vertical center area of the door plate is likely to occur. In particular, in the case of an entrance door, environmental differences such as a temperature difference and a humidity difference between the outdoor side and the indoor side may become large, and the above-mentioned inconvenience becomes more remarkable due to the environmental difference. As described above, warping deformation occurs in the vertical center region of the door plate, and in particular, when the vertical warping occurs in the vertical center region on the side opposite to the open side of the door plate, the projecting portion becomes the base end of the door plate. Opening / closing failure of the door plate occurs due to, for example, interference with the door stop of the door frame located on the side.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in view of such inconvenience, and its object is to suppress the warpage of the door plate and prevent the door plate from being opened and closed poorly. An object of the present invention is to provide a door warpage preventing member and a door warpage preventing structure.

In order to achieve the above object, the present invention includes a warp regulating body facing a door surface of a door plate, and is capable of regulating a warp deformation of the door plate toward the warp regulating body. , Is adopted. According to such a configuration, warpage of the door plate is suppressed, and poor opening and closing of the door plate due to the warpage can be prevented.

The present invention also relates to a door warpage preventing member provided on a door, which is disposed on a side opposite to an opening direction of the door plate and is provided at a rotation fulcrum side area in a door surface of the door plate. A configuration is adopted in which a warp regulating body is provided so as to be able to regulate warpage of the door plate toward the warp regulating body. According to such a configuration, it is possible to suppress inward warpage in which the door surface protrudes in a direction opposite to the opening direction of the door plate, and it is possible to prevent poor opening and closing of the door plate due to the inward warpage. In particular, since the warp regulating body is provided in the rotation fulcrum-side area in the door surface of the door plate, it hardly affects the entrance and exit of the door opening, and furthermore, the warp is restricted to a portion which is most effective in suppressing the inside bow. The body can be arranged, and poor opening and closing of the door plate can be efficiently suppressed.

Further, the present invention is a door warpage preventing structure in which a door warpage preventing member is attached to a door surface side of a door plate, wherein the door warping preventing member is positioned relative to the door surface of the door plate. In this case, the above-described object can be achieved by including a warp regulating body that is provided so as to be able to regulate the warpage of the door plate toward the warp regulating body. Here, a configuration in which a door surface protection member is provided between the door surface and the warp regulating body may be used together. Thus, it is possible to prevent the door surface from being damaged when the warpage restrictor comes into contact with the door surface.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION It is preferable that the warp regulating member in the present invention is constituted by a roller, and the center axis of rotation of the roller is disposed substantially along the vertical direction of the door plate. With this configuration, it is possible to reduce the reaction force applied to the door surface from the warp regulating body when the door plate is closed in a state where the door surface is in contact with the warpage regulating body by rotating the roller, The surface can be made hard to be damaged. In addition, even if the roller contacts the door surface, the frictional resistance that hinders the opening and closing of the door plate due to the slight rotation or slippage of the roller can be minimized, and the smooth opening and closing of the door can be ensured. Becomes

In this specification, the term "door surface" refers to the front and back surfaces of the door body, and does not include both upper and lower end surfaces and left and right end surfaces.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic front view of a single-opening type entrance door to which a structure for preventing warpage of a door according to the present embodiment is applied, as viewed from the indoor side, and FIG. An enlarged cross-sectional view taken along line -A is shown. FIG. 3 is an enlarged perspective view of a main part of FIG. In these figures, an entrance door 10 as an opening door includes a wooden door plate 11 that can be opened to the outdoor side, which is a depth side in FIG. 1, and a door frame 12 that is arranged along the outer periphery of the door plate 11. Publicly-known pivot hinges 16, 16 provided at upper and lower ends on the left end side of the door plate 11 in FIG. 1 to rotatably connect the door plate 11 to the door frame 12, A door warp preventing member 18 provided in the vicinity of a base end side region B (rotation fulcrum side region) of the door plate 11 on the indoor side opposite to the opening direction, and the door warp preventing member 18 and the indoor position. And a receiving plate 19 as a door surface protection member provided between the door surface 11A and the door surface 11A.

As shown in FIG. 2, the door frame 12 has an end face 11B on the base end side of the door plate 11 in a closed state.
Includes a side end surface 12A, which is opposite to
The door surface 1 on the indoor side extends along the end surface 11B.
It is provided in a shape extending further to the indoor side than the surface position of 1A. Note that a door stop portion 12B located between the base end side region B of the door plate 11 and the door warpage preventing member 18 is continuously provided on the side end surface 12A.

The door warpage preventing member 18 includes a roller 21 which constitutes a warp regulating member which is disposed relatively to the door surface 11A on the indoor side, and a support 22 which rotatably supports the roller 21. Have been.

As shown in FIGS. 3 and 4, the support body 22 has a long base 26 extending in the vertical direction in surface contact with the side end face 12A, and a substantially flat surface with respect to the surface of the base 26. A pair of substantially L-shaped support pieces 27 and 28 extending in a substantially horizontal direction from a substantially central portion in the longitudinal direction of the base portion 26 in a direction orthogonal to the base portion and having a distal end slightly bent toward the door surface 11A. And a reinforcing shaft 30 positioned between the base regions of the support pieces 27 and 28, and a support shaft that spans between the distal ends 27A and 28A of the support pieces 27 and 28 and rotatably supports the roller 21. 31.

The base portion 26 is formed with two through holes 33 at both left and right sides in FIG. 4A with respect to the support pieces 27 and 28, and these through holes 33 are particularly limited. However, it is provided in a two-stage hole shape that allows the head of the screw 34 to be embedded. The base 26 is fixed to the side end surface 12 </ b> A of the door frame 12 using screws 34 inserted into the through holes 33. On this occasion,
The base portion 26 has its long width direction substantially coincident with the vertical direction of the side end surface 12A, and the distal end portion 2 of the support pieces 27, 28.
7A and 28A are fixed to the indoor side rather than the door stop 12B in a direction facing the door surface 11A. Accordingly, the rotation center axis C of the roller 21 is disposed substantially along the vertical direction of the door plate 11. Further, in an initial state in which the door plate 11 is not warped, the roller 21 is disposed such that the distal end 21A of the outer peripheral surface is separated from the receiving plate 19 by about 2 mm toward the indoor side.

The receiving plate 19 is formed in a substantially rectangular shape by a stainless steel plate, and is bonded to the indoor side door surface 11A via a double-sided adhesive tape, a screw or the like.

In order to confirm the effect of preventing the warpage of the entrance door 10 having the above configuration, the present inventor has proposed that the entrance door 10 be constructed as follows:
The following experiment was conducted with an entrance door that was not provided with the door warpage prevention member 18. In other words, for each entrance door, the vertical center area of the base end side area B of the door plate 11 is so set that the vertical center area of the door plate 11 forcibly generates a warp deformation (inward warp) projecting indoors. 50 in part
kga indoor tensile load is applied and JISA4
The opening / closing operation of the door plate 11 was performed 200,000 times in the opening / closing durability test of 702 (door set).

According to this experiment, the warpage preventing member 1 for a door was used.
In the entrance door 10 provided with the front door 8, the warp deformation amount of the substantially central portion E (hereinafter, simply referred to as “central portion E”) in the vertical direction in the base end region B (see FIG. 1) of the door plate 11 is: In the initial state, the minimum separation width between the roller 21 and the receiving plate 19 is suppressed to 2 mm, whereas in the front door without the warpage preventing member 18 for the door, the warpage deformation of the central portion E is 3. 6 mm. When the opening / closing operation is repeatedly performed, the entrance door 10 having the door warpage preventing member 18 has no problem in opening and closing the door plate 11, but the entrance door not including the door warping preventing member 18. As for the door, the vicinity of the central portion E hit the door stop portion 12B, and the opening and closing of the door plate 11 became difficult. In addition, entrance door 1
With respect to 0, the above-described experiment was performed while changing the magnitude of the tensile load. As a result, up to a tensile load of about 20 kgf, the vicinity of the central portion E is near the outer peripheral surface tip side 21A of the roller 21A.
And the amount of warpage of the central portion E increases as the tensile load increases. However, when the tensile load exceeds 20 kgf, the vicinity of the central portion E is closer to the outer peripheral surface tip side 2 of the roller 21.
1A, the amount of warpage of the central portion E hardly changed even when the tensile load was increased. That is, a tensile load of 6
Even at 0 kgf, the warpage of the central part E is about 2
mm.

Therefore, according to the above experimental results, even if a tensile load applied to the indoor side of 20 kgf or more acts on the vicinity of the central portion E, the amount of warpage of the door plate 11 is most deformed. It can be clearly understood that the opening and closing operation of the door plate 11 can be performed without any trouble over a long period of time, being suppressed to about 2 mm at the portion where the opening is performed.

In the above embodiment, the door warp preventing member 18 is disposed at one position near the center E. However, the present invention is not limited to this, and the door warp preventing member 18 may be disposed at a plurality of positions along the vertical direction of the door plate 11. A warp preventing member 18 can be provided.

Further, the warp regulating member is not limited to the roller 21, and various members which can be opposed to the door surface 11A of the door plate 11 can be adopted. However, when the warp regulating body is made of a member capable of reducing the frictional resistance with the door plate 11 such as the roller 21, the door is smoothly opened and closed, and the warp regulating body contacts the door plate 11. This can prevent the door surface 11A from being scratched.

Further, the configuration of the door warpage countermeasure member in the present invention and the mounting position thereof are not limited to the illustrated configuration example, and the warp regulating body faces at least one of the indoor or outdoor door surfaces. Various changes are possible as long as the warp deformation of the door plate 11 to the warp regulating body is suppressed so as not to hinder the opening and closing operation.

[0023]

As described above, according to the present invention,
Since the warp regulating body opposed to the door surface is adopted, and the warp deformation of the door plate toward the warp regulating body side can be regulated, the warp deformation of the door plate can be suppressed, and the door caused by the warp deformation can be suppressed. Poor opening and closing of the plate can be prevented.

Further, since the warp regulating body is disposed on the side opposite to the opening direction of the door plate and is opposed to the rotation fulcrum side area in the door surface of the door plate, the door is located on the side opposite to the opening direction of the door plate. Warpage of the surface overhang can be efficiently suppressed.

Further, since the warp regulating member is constituted by a roller, and the center axis of rotation of the roller is disposed substantially along the vertical direction of the door plate, the reaction force applied to the door surface from the warp regulating member is reduced. The door surface can be made less likely to be scratched.

Further, since the door surface protecting member is provided between the door surface and the warp regulating body, it is possible to prevent the door surface from being damaged when the warp regulating body comes into contact with the door surface.
