  In the following, the present invention will be described in more detail with reference to the example of the drawings. In FIGS. 1 to 4, A designates that the door 2 is suspended and supported by a hinge 13 on the suspension side vertical frame 11 of the door frame 1. It is a door with a frame for an entrance provided with a finger pinching prevention device, and the finger pinching prevention device of the door A with the frame is made of metal or synthetic resin from the prospective surface of the hanging side vertical frame 11 toward the door surface. A long cover plate 3 is slidably disposed so as to be able to rotate in the door opening / closing direction in an urging state in the door opening direction, and the free end of the cover plate 3 is slid against the finding surface of the door 2. The opening / closing gap between the hanging side vertical frame 11 and the hanging side expected surface of the door 2 can be sealed by making it possible to always follow and rotate according to the opening and closing of the door.

  The door A with a frame of this example is a steel door frame 1 which is formed by bending a steel plate and welding the ends in the longitudinal direction, and a front and back surface plates 22 made of steel plate on a middle bone 21 obtained by bending the steel plate. And is provided with a steel door 2 formed by filling a heat insulating and soundproofing material (not shown). An airtight material 12 is mounted on the indoor side of the door frame 1, and the airtight material 12 is provided with a door 2. It is assumed that the airtightness is ensured by contacting the end portion of the indoor side finding surface. At this time, the door A with a frame is provided with a door closer (not shown). Therefore, when the door closer automatically closes the door 2, the space between the suspension side vertical frame 11 and the suspension side expected surface of the door 2. In order to forcibly reduce the opening / closing gap of the door 2 and to close the door 2, when the door is closed, a finger of a person including an infant or a child is sandwiched between the opening / closing gaps on the back surface of the door 2. Where there is a risk of injuries, the above-mentioned opening / closing gap is inevitably generated when the door is opened / closed by providing the above-described finger pinching prevention device on the side of the door suspension to make it impossible to insert a finger. It is assured of the safety.

  The cover plate 3 installed on the door A with the frame has a length equivalent to the height of the door 2 or a shorter length than that of the door 2. The lower end position of 2 or somewhat from the lower end, for example, a length of about 1 to 1.5 m from a lower position of about 10 cm, and in this example, a length of about 1.2 to 1.4 m from the lower position. It is as. At this time, the width of the cover plate 3 is, for example, about 10 to 20 cm, and about 13 cm in this example, so that the cover plate 3 is long enough to block the opening and closing gaps in the vertical direction. It is in the shape of a shaku band.

  The cover plate 3 is a metal having a wall thickness of about 1 to 2 mm, for example, made of steel or aluminum subjected to plate processing, or made of aluminum by an extruded material. At this time, the cover plate 3 The free end is bent or curved toward the outdoor side to have a cross-sectional shape that slides in contact with the finding surface of the door 2. Accordingly, the cover plate 3 has a cross-sectional shape such as a U-shape or a V-shape, and a cross-sectional shape such as a curved dish shape or a bowl shape. In this example, the cover plate 3 has an obtuse angle, For example, it has a substantially V-shaped cross-sectional shape bent at about 130 to 140 °. At this time, the cover plate 3 is configured such that a sliding contact member 31 is disposed at a free end thereof to cover the free end. The sliding contact member 31 has a frictional resistance as small as possible and a free end. In order not to generate noise at the time of the sliding contact, for example, a material such as synthetic resin or synthetic rubber is used to be fitted and fixed to the free end.

  In this example, the protruding arrangement of the cover plate 3 that can freely rotate in the door opening / closing direction in the door opening direction biased state is formed by using the blade of the spring hinge 32 as the suspension side vertical frame 11 and the cover plate. 3 is fixed to each. That is, by using the spring hinge 4, the cover plate 3 is biased in the door opening direction, ensuring the above-described regular followability of rotation, and being installed on the suspension side vertical frame 11. To get.

  At this time, the blade of the spring hinge 4 is fixed to the suspension base vertical frame 11 by using a seat plate 5 screwed to the suspension base vertical frame 11 and the blade is fixed to the fixed piece 52 of the seat plate 5. And is inserted into an opening formed in the suspending-side vertical frame 11 and arranged orthogonally to the suspending-side vertical frame 11.

  In this example, the seat plate 5 is cut and raised on a metal plate, for example, a stainless steel plate, and the fixed piece 52 is erected from the intermediate rectangular through hole 51 and its one side edge to the back side. The screw through-holes 53 are arranged on the upper and lower sides and the fixed piece 52, one blade of the spring hinge 4 is overlapped with the fixed piece 52 and screwed, and the shaft portion of the spring hinge 4 and the other blade From the opening of the hanging base side vertical frame 11, that is, the rectangular opening formed on the indoor side expected surface of the hanging base side vertical frame 11, and one blade fixed to the fixed piece 52. Are inserted into the suspension base vertical frame 11 from the upper and lower screw through holes 53 of the rectangular through hole 51, and one end of the cover plate 3 is overlapped with the other blade of the spring hinge 4. For example, it is fixed by bolts and nuts. In this manner, the spring hinge 4 is fixed to the suspension base vertical frame 11 via the seat plate 5 and the cover plate 3 is fixed to the spring hinge 4.

  Accordingly, the spring hinge 4 urges the other blade and the cover plate 4 fixed to the other blade in the door opening direction, and the urging force causes the free end of the cover plate 3 to face the door 2 surface. The urging force is accumulated by sliding in contact with each other and closing the door 2, in this example, closing by the door closer. At this time, since one blade of the spring hinge 4 is arranged orthogonally to the indoor side expected surface of the suspension side vertical frame 11, for example, the one blade is expected to be indoor side of the suspension side vertical frame 11. Compared with the case where the door 2 is arranged in parallel with the surface, the other blade, that is, the rotation range of the cover plate 3 follows the entire opening / closing angle of the door 2 from the closed state of the door 2 to the opened state. Therefore, the urging force of the cover plate is lost during the opening and closing of the door 2, the followability of the cover plate 3 is impaired, and the gap between the cover plate 3 and the door 2 is found. It can be made trouble-free.

  At this time, the cover plate 3 is bent or curved, in this example, substantially V-shaped, so that the position of the free end is further displaced from the other blade toward the door 2 side. Even when the angle is opened to exceed 1/4 circle, it is possible to ensure the follow-up turning property.

  The door A with a frame of the present example is formed by previously forming the opening in the vertical frame 11 of the suspension frame of the door frame 1 at the factory, so that the steel door frame 1 and the door 2 are made into a newly built structure. The cover plate 3 can be supplied as an accessory or as an option to be installed, and the opening is formed by being transparently formed on the hanging frame side vertical frame 11 of the door frame 1 in the field. Then, the cover plate 3 can be retrofitted to the existing door 1 with a frame, and the door frame 1 of the existing door A with a frame remains, for example, an existing door such as a press door. The cover plate 3 can be installed in the same way when the door is removed and the new steel door 2 is installed in exchange for the door.

  FIGS. 5 and 6 show an example in which the seat plate 5 is configured to be fitted into an opening formed in the factory of the suspension side vertical frame 11 and the spring hinge 4 is fixed thereto, and the cover plate at this time 3 shows an example in which the opening is closed with a decorative cover 56 when the cover plate 3 is not installed by using the cover plate 3 as an option. Although the same shape as the seat plate 5 in FIGS. 1 to 4 is obtained by fitting into the opening in accordance with the opening of the vertical frame 11, this is different from the outside dimension. At the back of the opening of the suspension side vertical frame 11, a box 54 having upper and lower protrusions 55 is fixed. The seat plate 5 is fitted into the opening, and the upper and lower protrusions are inserted into the upper and lower screw holes. The seat plate 5 is attached to the suspension side vertical frame 11 by screwing to 55. As to the expected surface flush is as good appearance fixing. Since the remainder is not different from the example of FIGS. 1 to 4 described above, the same reference numerals are given and redundant description is omitted.

The closing is performed by fixing the decorative cover 56 with a good appearance so as to be flush with the expected surface by screwing the upper and lower protruding pieces 55 from the screw holes in the same manner as the seat plate 5.

  7 and 8 show another example of installation of the cover plate 3 with respect to the hanging side vertical frame 11. In this example, the blades of the spring hinge 4 are fixed to the hanging side vertical frame 11. In this case, the magnet 7 is arranged on the blade or the support plate 6 installed on the blade, and the magnetic plate is attracted to the suspension side vertical frame 11, whereby the cover plate 3 of this example is In this case, it can be retrofitted as easily as possible by, for example, a Sunday carpentry operation without the need for construction such as through-opening.

  In this example, the blades of the spring hinge 4 are fixed to the suspension side vertical frame 11 by using a support plate 6 having the same length as the cover plate 3, and a magnet 7, for example, a rubber magnet is integrated on the back surface of the support plate 6. And fixing one blade of the spring hinge 4 to the support plate 6.

  In this example, the support plate 6 crosses and protrudes, for example, at right angles to the support substrate 61 along the expected surface of the suspension base vertical frame 11 and the outdoor end of the support substrate 61, so that the suspension base vertical frame A hook piece 62 for positioning the support plate 6 by hooking and engaging with an upright projection of the airtight material receiving groove of the airtight material, and folded back from the indoor end of the support substrate 61 along the support substrate 61. And a folded plate 63 in which a receiving groove for receiving the one blade is formed, and is made the same length as the cover plate 3, for example, made of aluminum or synthetic resin by an extruded material.

  The magnet 7 having the same length as the support plate 6 is integrally fixed to the back surface of the support substrate 61, that is, the surface facing the suspension side vertical frame 11 by, for example, bonding. By inserting one blade of the spring hinge 4 into the receiving groove between the support substrate 61 and the folded piece 63 and screwing the one blade on the folded piece 63, the spring plate 4 is fixed to the support plate 6. The end of the cover plate 3 is overlapped with the other blades of the spring hinge 4 fixed to the support plate 6 and screwed to fix the end of the cover plate 3 to the spring hinge 4. Is fixed. At this time, the spring hinge 4 is arranged in the same manner as the above by disposing one blade in parallel with the suspension side vertical frame 11 so that the inside and outside of the case shown in FIGS. It is assumed that it was biased toward the door opening direction.

  Thus, the magnet 7 is magnetically attracted to the expected surface of the hanging side vertical frame 11 so that the cover plate 3 is installed on the hanging side vertical frame 11 and the same as in the examples of FIGS. According to the opening and closing of the door, the free end of the cover plate 3 can always follow and rotate so that the free end of the cover plate 3 slides in contact with the surface of the door 2.

  In this example, in addition to the simplicity of installation of the cover plate 3, it is possible to attach and detach the cover plate 3 so that it can be installed again after the cover plate 3 is removed. Can be suitable.
