Description

  TECHNICAL FIELD The present invention relates to a toe padding prevention material for a hinged door for preventing toe padding in a gap generated between the lower surface and the floor surface of the hinged door, and a hinged door using the same.

  In general, a hinged door provided in a house is rotatably supported by a vertical frame member in a gate-shaped door frame via a hinge, and prevents interference between the lower surface of the hinged door and the floor surface. The gap is formed. In addition, in order to secure a ventilation channel that connects the spaces partitioned by the hinged doors, a gap for ventilation of about 10 to 30 mm in height called undercut is formed between the lower surface of the hinged door and the floor surface. Sometimes.

  As described above, a gap having a predetermined height is formed between the lower surface of the hinged door and the floor surface. If the height of the gap exceeds, for example, 7 mm, the toes of the toes are moved when the hinged door is opened and closed. It becomes easy to get caught in the gap, and the risk of filling the toes increases.

  Therefore, conventionally, a measure has been taken to prevent toe padding by attaching a covering material to the lower surface of the hinged door and reducing the gap generated between the lower surface of the hinged door and the floor surface (for example, Patent Documents). 1 and 2).

  However, since the covering material to be attached to the lower surface of the conventional hinged door is a long object that covers the substantially entire length of the suspension source side from the door end side of the lower surface of the hinged door, the material cost is high and the handling is troublesome. Moreover, there is a restriction that it cannot be applied to a hinged door provided with functional members such as a floor stopper and air tight on the lower surface. Furthermore, when a gap for ventilation is formed between the lower surface of the hinged door and the floor surface, most of the gap for ventilation is blocked by the covering material, resulting in a decrease in ventilation performance. There was a malfunction. Moreover, it was necessary to prepare the coating | covering material which has the width | variety according to the door thickness separately with respect to the hinged door from which door thickness differs, and there existed a malfunction that a versatility was scarce.

  Therefore, the present invention eliminates the above-mentioned problems, is inexpensive and easy to handle, can be applied to a hinged door provided with a functional member on the lower surface, and has versatility that does not adversely affect ventilation performance. An object is to provide an excellent toe padding prevention material for hinged doors and a hinged door using the same.

  The toe padding prevention material 20 for the hinged door according to the present invention is attached to the doorside lower surface 10a of the hinged door 1, and the gap 6 generated between the doorside lower surface 10a and the floor surface 5 is reduced to pack the toes. It has a pair of left and right side frame portions 21 and 21 and a front end frame portion 22 that connects the front ends of the side frame portions 21 and 21, and is formed in a U-shaped frame shape as a whole. In the attached state to the hinged door 1, the pair of left and right side frame portions 21, 21 are arranged on the front and back surfaces 11 of the hinged door 1 so as to avoid the central portion in the door thickness direction on the door-side lower surface 10 a of the hinged door 1. 12 is arranged along the door end side lower end portion of the door 12, and the tip frame portion 22 is arranged along the lower end portion of the door end side end surface 13 of the hinged door 1.

  The pair of left and right side frame portions 21, 21 can be separated. Specifically, notches 24 and 24 for separating the pair of left and right side frame portions 21 and 21 are formed in the distal end frame portion 22 in advance.

  The hinged door 1 of the present invention is characterized in that the above-mentioned toe-stuffing prevention material 20 is attached to the door-end-side lower surface 10a.

  By attaching the toe padding prevention material of this invention to the doorside side lower surface of the hinged door, it becomes difficult for the toes of the foot to be caught in the gap formed between the doorside lower surface of the hinged door and the floor surface, and It can be effectively prevented. In addition, by using a toe padding prevention material made of a soft material in particular, the toes of the toes may come into contact with the toe padding prevention material or be caught in a gap generated between the lower surface of the hinged door and the floor surface. Even if there is something wrong, you can soften the hit and make it hard to cause injury.

  Moreover, the toe padding prevention material is not a long one that covers substantially the entire length of the suspension door side from the door tip side of the lower surface of the hinged door like a conventional coating material, but a short length that only covers the lower surface of the hinge door. Therefore, the material cost can be kept low and the cost can be reduced, and the mounting operation and the replacement operation can be easily performed with easy handling. Furthermore, even when a gap for ventilation is formed between the lower surface of the hinged door and the floor surface, only a part on the door tip side in the gap for ventilation is only blocked by the toe padding prevention material. Therefore, ventilation performance can be maintained well.

  In addition, the toe padding prevention material is formed in a U-shaped frame shape and is attached so as to avoid the central part in the door thickness direction on the lower surface of the hinged door, so that a functional member such as a floor stopper is attached to the door. It can attach without interfering with a functional member also to the hinged door which was provided in the front side lower surface.

  Furthermore, since the toe padding prevention material can cut the left and right side frame parts by cutting the tip frame part along the notch, even for hinged doors with different door thicknesses, depending on the door thickness A side frame portion separated at a predetermined interval can be attached to prevent toe padding. Furthermore, for example, a side frame portion separated so as not to interfere with the functional member, even for a hinged door in which a functional member such as air tight is provided over substantially the entire length of the lower end from the door end side to the suspension source side. It can be attached to prevent toe padding. Therefore, it is excellent in versatility.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The hinged door 1 according to an embodiment of the present invention is provided in a house, and is arranged, for example, between a living room and a hallway or between a living room and a living room. As shown in FIG. 1, the hinged door 1 is rotatably supported by one vertical frame member 3 in a gate-shaped door frame 2 via hinges 4, 4. The enclosed opening is opened and closed. And between the lower surface 10 and the floor surface 5 of the hinged door 1, the clearance gap (undercut) 6 for about 10 mm in height is formed. The gap 6 also serves as an interference prevention gap for preventing interference between the lower surface 10 of the hinged door 1 and the floor surface 5.

  In the hinged door 1, since the toes of the toes are easily caught in the gap 6 during the opening and closing operation, there is a risk of clogging with the toes, and measures are taken to prevent this. That is, as shown in FIGS. 1 and 2, the toe padding preventing material 20 is attached only to the door tip side of the lower surface 10 of the hinged door 1, and is generated between the door tip side lower surface 10 a of the hinged door 1 and the floor surface 5. By narrowing the gap 6, the toes are prevented.

  In addition, if the toe padding prevention material 20 is attached over substantially the entire length from the door tip side of the lower surface 10 of the hinged door 1 to the suspension base side, the gap 6 is reduced over substantially the entire length to reliably prevent toe padding. can do. However, the user passes through the opening at a position close to the door end side of the hinged door 1 while opening the hinged door 1 by operating the knob 7 provided on the doortip sides of the front and back surfaces 11 and 12 of the hinged door 1. Therefore, the toes are most likely to be sandwiched between the door-side lower surface 10 a of the hinged door 1 and the floor surface 5 in the gap 6. Therefore, just attaching the toe padding prevention material 20 only to the door side lower surface 10a of the hinged door 1 can effectively prevent toe padding.

  The toe padding prevention material 20 is made of, for example, a soft material such as soft rubber or soft synthetic resin. As shown in FIG. 3, the pair of left and right side frame portions 21, 21 and the tips of the side frame portions 21, 21 are connected to each other. Are formed in a U-shaped frame shape in plan view. The toe padding preventing material 20 has a length L1 of about 50 mm, a width L2 of about 38 mm slightly longer than the door thickness of about 36 mm, and a distance L3 between the side frame portions 21 and 21 of about 18 mm. Yes.

  The side frame portion 21 includes a bottom piece 21a and a rising piece 21b that rises from an outer end along the longitudinal direction of the bottom piece 21a, and has a substantially L-shaped cross section. The distal end frame portion 22 includes a bottom piece 22a and a rising piece 22b that rises from an outer end portion along the longitudinal direction of the bottom piece 22a, and has a substantially L-shaped cross section. And the bottom pieces 21a and 21a of the side frame parts 21 and 21 and the bottom piece 22a of the front-end | tip frame part 22 are continuing in U shape so that those upper surfaces and lower surfaces may become flush | level. Further, the rising pieces 21b and 21b of the side frame portions 21 and 21 and the rising pieces 22b of the distal end frame portion 22 are continuous in a U-shape.

  In the toe padding prevention material 20, a double-sided tape 23 is attached in advance to the upper surfaces of the bottom pieces 21 a and 21 a of the side frame portions 21 and 21 and the upper surface of the bottom piece 22 a of the distal end frame portion 22. Further, the front end frame portion 22 is formed with notches 24 and 24 for separating the side frame portions 21 and 21 in advance. In the present embodiment, the notches 24 and 24 are formed at two locations on the tip frame portion 22, but may be one location.

  When attaching the toe padding prevention material 20 having the above-described configuration, as shown in FIG. 4, the outer periphery of the lower end portion of the door toe side of the hinged door 1 is surrounded by the rising pieces 21b, 21b, 22b, and the bottom pieces 21a, 21a, 22a. Is attached to the door side lower surface 10a of the hinged door 1 via a double-sided tape 23. In this bonding, for example, an adhesive may be used.

  In the state where the toe padding prevention material 20 is attached to the hinged door 1, the side frame portions 21, 21 are arranged on the front and back surfaces 11 of the hinged door 1 so as to avoid the center portion in the door thickness direction on the door tip side lower surface 10 a of the hinged door 1. 12 is disposed along the lower end portion of the door-end side, and the front end frame portion 22 is disposed along the lower end portion of the door-end side end surface 13 of the hinged door 1.

  As described above, the short toe-stuffing prevention material 20 is attached only to the door-end-side lower surface 10a of the hinged door 1, and the door-end-side lower surface 10a and the floor surface 5 of the hinged door 1 in which the toes are most likely to be sandwiched. Since the space between the two is narrowed, the toes can be effectively prevented. Further, since the toe padding prevention material 20 is made of a soft material, the toes of the toes contact the toe padding prevention material 20, or the gap 6 generated between the door side lower surface 10 a of the hinged door 1 and the floor surface 5. Even if you get caught, you can reduce the chance of injury and prevent injury. Moreover, compared to the conventional case of using a long covering material that covers the entire lower surface of the hinged door, the material cost of the toe padding prevention material 20 can be reduced and the cost can be reduced. The handling of the stuffing prevention material 20 can be facilitated, and the attaching operation and the replacing operation can be easily performed. Furthermore, since only a part of the door gap side of the ventilation gap 6 is blocked, the ventilation performance can be maintained satisfactorily.

  Moreover, since the toe padding prevention material 20 is formed in a U-shaped frame shape and is attached so as to avoid the central portion in the door thickness direction on the door-side lower surface 10a of the hinged door 1, as shown in FIG. For example, it can attach without interfering with the functional member 30 also to the hinged door 1 which provided functional members, such as the floor surface stopper 30, in the door thickness direction center part of the door tip side lower surface 10a.

  Further, as shown in FIG. 6, the toe padding prevention material 20 cuts the side frame portions 21, 21 by cutting the front end frame portion 22 along the cuts 24, 24 using a cutter or the like. Can do. Therefore, as shown in FIG. 7, the side frame portions 21 and 21 separated by an interval corresponding to the door thickness are attached to the hinged door 1 having a different door thickness (for example, a door thickness of about 40 mm). Can prevent toe stuffing. Further, as shown in FIG. 8, for example, the functional member 31 interferes with the hinged door 1 in which a functional member such as an air tight 31 is provided over substantially the entire length from the door end side of the lower surface 10 to the suspension base side. The side frame portions 21 and 21 separated so as not to be attached can be attached to prevent toe padding.

  The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, the toe padding prevention material of the present invention may be applied not only to a hinged door provided in a house, but also to a hinged door as a front door or various hinged doors provided in a building other than a house.
