Description

  The present invention relates to a finger pinching prevention device adapted to prevent a finger from being caught in a gap by covering a gap formed between a door body and a door frame when opening and closing a door. .

  Conventionally, when opening and closing a door, there has been reported a case in which an infant or the like erroneously pinches a finger in a gap or a gap formed between a door body and a door frame (vertical frame). Various structures have been proposed as finger pinch prevention devices that prevent an accident in which a finger is pinched between the door body and the door frame.

  For example, according to Patent Document 1, when the door is opened so that the baby does not get injured by having a finger caught in the V-shaped gap formed between the door body and the door frame, between the door body and the door frame It is disclosed that the resulting gap is covered by a safety film. According to Patent Document 1, one end of the safety film is fixed to a door frame with a double-sided tape, a screw, and a plate plate made of plastic.

  Further, Patent Document 2 discloses a finger pinch prevention device for a framed door. This device discloses fixing a cover plate having a substantially V-shaped cross-sectional shape bent at an obtuse angle to a door frame through a spring hinge. By using a spring hinge, the cover plate is biased in the door opening direction to ensure its normal follow-up pivotability. A sliding contact member is disposed at the free end of the cover plate opposite to the fixed side. The sliding contact member is fitted and fixed to the free end using a material such as synthetic resin or synthetic rubber so that the frictional resistance is as small as possible and noise is not generated at the time of contact with the free end. It is assumed.

  However, in the safety film described in Patent Document 1, since only one end thereof is fixed to the door frame, there is a concern in the followability of the safety film to the door body when the door is opened and closed. Further, even with the finger pinch prevention device described in Patent Document 2, by using a spring hinge, the cover plate is merely urged in the door opening direction, and there is a gap between the door body and the cover plate. There is a concern that arises.

  Moreover, according to the description of Patent Document 1, one end of the safety film is fixed to the door frame with a double-sided tape and a screw, a plastic plate plate, the safety film is slightly bent inward, and the door is opened. It is in contact with the door even when closed. Therefore, a force is exerted on the door from the safety film, and there is a high possibility that the door will move in an opening direction. Furthermore, in the finger pinch prevention device described in Patent Document 2, since the spring hinge is used, a force acts on the door from the finger pinch prevention device, and there is a high possibility that the door will move freely. Such free movement of the door can increase the risk of a finger or the like being caught in the gap between the door and the door frame.

  Therefore, the present invention has been made in view of the above problems, and it is possible to prevent finger pinching of an infant or the like into a gap between a door body and a door frame more securely. It aims at providing a prevention device.

In order to achieve the above object, one aspect of the present invention is

  Hereinafter, an embodiment according to the present invention will be described based on the attached drawings. The same parts (or configurations) are given the same reference numerals, and their names and functions are also the same. Therefore, detailed description about them will not be repeated.

  FIG. 1 is a schematic configuration view of a door 11 to which the finger pinching prevention device 10 according to the first embodiment of the present invention is applied. In the door 11, the door body 12 is attached to the vertical frame 16 a of the door frame 16 by a hinge or hinge 14. In FIG. 1, the door body 12 is shown opened about 80 ° with respect to the door frame 16. Although only one hinge 14 is shown in FIG. 1, the remaining hinges (see FIG. 2) are hidden by the finger pinch prevention device 10.

  FIG. 2A shows the finger pinch prevention device 10 of FIG. 1 as viewed from the upper side in FIG. Further, FIG. 2 (b) shows the finger pinching prevention device 10 in a state in which the door body 12 is closed in FIG. Furthermore, FIG. 3 is a schematic configuration view of the finger pinch prevention device 10, in which the finger pinch prevention device in a state of being flatly extended in a sheet shape, before being attached to the door body 12 and the door frame 16 or after being removed therefrom. FIG. 10 is a view of 10 from a position corresponding to the upper side of FIG.

  As shown in FIGS. 1 to 3, the finger pinching prevention device 10 includes a sheet-like member 20. The sheet-like member 20 includes four strips 22. The four strips 22 are respectively elongated members and extend in the longitudinal direction D1 (see FIG. 1). Here, the lengths in the longitudinal direction D1 of the four strips 22 are the same. The four strip members 22 are arranged in the width direction D2 orthogonal to the longitudinal direction D1 as shown in FIG. 3 and connected to each other. The longitudinal direction D1 corresponds to the first direction, and the width direction D2 corresponds to the second direction.

  Here, among the four belts 22, in FIG. 1 and FIG. 2, the belt closest to the door main body 12 is the first belt 22a, the belt next to it is the second belt 22b, and further next to it. The band is referred to as a third band 22c, and the band closest to the door frame 16 is referred to as a fourth band 22d. The first to fourth strip members 22 a, 22 b, 22 c and 22 d are not particularly covered, and are connected by a connection tape 24. The connection tape 24 is an adhesive tape. The connection tape 24 may be repeatedly stuck or peeled off, but may be a disposable adhesive tape. In addition, in the finger pinch prevention device 10, the attachment location of the connection tape 24 is mainly determined on the inner side when the connection portion 26 between the adjacent strip members 22 is bent.

  The first strip 22a is attached to the door body 12 as shown in FIG. Here, the first strip 22a is attached to the door body 12 using the double-sided tape 28a. Similarly, the fourth strip 22 d is attached to the door frame 16. And similarly, the fourth strip 22 d is attached to the door frame 16 using the double-sided tape 28 b. In addition, in FIG. 2, these double-sided tapes 28a and 28b are abbreviate | omitted. In this case, the first strip 22a corresponds to the first end of the sheet-like member 20 in the second direction, and the double-sided tape 28a corresponds to the first attachment portion for attaching the first strip 22a to the door body 12. . The fourth strip 22d corresponds to a second end opposite to the first end of the sheet member 20 in the second direction, and the double-sided tape 28b is for attaching the fourth strip 22d to the door frame 16. It corresponds to the second mounting portion.

  The strips 22 have the same length L in the longitudinal direction D1 as described above. The length L of the longitudinal direction D1 is determined so that the height range in which pinching of a finger of an infant or the like is likely to occur can be covered with the finger pinching prevention device 10 (see FIG. 1). However, the length L of the longitudinal direction D1 is not limited to this. For example, the length L of the strip 22 in the longitudinal direction D1, that is, the length L of the sheet-like member 20 in the longitudinal direction D1 may be substantially equal to the height 12H of the door body 12. Also, for example, when the finger pinch prevention device 10 is applied between the hinges 14 of the door 11, the length L of the longitudinal direction D1 of the strip 22 is the length between the hinges 14 of the door 11 or a length shorter than that. It may be taken. Furthermore, when the finger pinch prevention device 10 is applied between the lower hinge 14 of the door 11 and the floor, the length L of the longitudinal direction D1 of the strip 22 is the length between the lower hinge 14 of the door 11 and the floor Alternatively, the length may be shorter than that. The lengths in the longitudinal direction D1 of the first to fourth strip members 22a, 22b, 22c, 22d may be different from each other, and may be designed arbitrarily.

  These strips 22 have a length or a width in the width direction D2 according to their arrangement. The first strip 22a and the fourth strip 22d each have a width W1 (see FIG. 3) that can ensure sufficient attachment to the door body 12 and the door frame 16. On the other hand, when the door body 12 as shown in FIG. 1 and FIG. The width W2 of the length that enables tracking the change in the relative position of the door body 12 and the door frame 16 so that the gap between the body 12 and the door frame 16 can be firmly covered (see FIG. 3) ) Is configured. Here, the width of the first strip 22a is substantially the same as the width of the fourth strip 22d, and the width of the second strip 22b is substantially the same as the width of the third strip 22c. Is not limited to these. The widths of the first to fourth strips 22a, 22b, 22c, 22d may be designed arbitrarily.

  The thicknesses t (see FIG. 3) of the first to fourth strips 22a, 22b, 22c, 22d are substantially the same here. The thickness t may be 1 cm or less, and here 1 mm or less. The thickness t may be, for example, in the range of 0.2 mm or more and 0.7 mm or less, preferably 0.3 mm or more and 0.5 mm or less, and more preferably about 0.5 mm.

  The first to fourth strips 22a, 22b, 22c and 22d are made of synthetic resin. Each of the strip members 22 can be elastically deformed, and can be in the form of a strip as shown in FIG. 1 or the like, or in a roll shape as schematically shown in FIG. 3 (b). Thus, each strip 22 can be deformed into either a strip or a roll. In addition, although these strip-shaped bodies 22 can be produced with a synthetic resin, respectively, they may be produced with another material. Specifically, when the strip 22 is made of a synthetic resin, it can be made of polyethylene (PE), polypropylene (PP), polyvinyl chloride, polyethylene terephthalate (PET) or the like. When the strip 22 is made of a synthetic resin, it may be made of a hard material, which enables the strip 22 to be made of a thinner material. Moreover, the strip 22 may be made of a synthetic resin sponge. The band 22 can be made of various materials.

  As shown in FIG. 1, in the finger pinching prevention device 10 of the above-described configuration, the first end of the sheet-like member 20, that is, the first strip 22 a is attached to the door body 12, and the second end of the sheet-like member 20. The fourth strip 22 d is attached to the door frame 16. And since the connection part 26 of an adjacent strip | belt-shaped body is only connected by the connection tape 24 as shown in FIG. 3, the finger pinch prevention apparatus 10 is the connection part 26 of a strip | belt-shaped body. Also easy to bend. Therefore, as shown in FIG. 1 and FIG. 2, in the finger pinch prevention device 10, when the door is opened and closed, bending occurs preferentially at the connection portion 26, whereby the gap between the door body 12 and the door frame 16 is preferable. Covered by Therefore, it becomes possible to prevent the pinching of an inadvertent finger such as an infant into the gap between the door body 12 and the door frame 16 more firmly.

  In addition, since the connecting portions 26 of adjacent strip members are only connected by the connecting tape 24 as shown in FIG. 3, the connecting tape 24 is a force or a straightening force to move the door. The bending force does not occur due to the connecting tape 24 itself. That is, the finger pinch prevention device 10, that is, the sheet-like member 20 can be freely bent without any special load at the connecting portion 26 which is a bent portion. Therefore, by providing the finger pinch prevention device 10, the door is not closed or opened by hand, so the finger pinch prevention device 10 is more excellent in safety.

  And in the finger pinch prevention device 10 provided so as to cover the gap between the door body 12 and the door frame 16, the connection portion 26c between the second strip 22b and the third strip 22c is, for example, as shown in FIG. As shown in FIG. 2, it has a substantially V-shape, particularly an acute-angled shape. In short, the finger pinch prevention device 10 has a truss structure when applied to the door 11. Therefore, the finger pinch prevention device 10 is structurally excellent in durability when, for example, the compression force CF as shown in FIG. 2A is applied. Therefore, the strength required for the sheet-like member 20 of the finger pinch prevention device 10, that is, the strength required for each strip 22 can be made relatively low. Therefore, as described above, the strip 22 can be made of a synthetic resin thin enough to be rolled.

  Further, since the strip 22 can be configured as a thin synthetic resin member, the strip 22 can be cut with a scissors or the like. Therefore, the size of the sheet-like member 20 can be easily adjusted according to the purpose of use of the user and the use location (for example, the size of the door body 12).

  Then, as described above, the strip 22 can be rolled into a roll (see FIG. 3B). Therefore, for example, when an infant or the like is absent, or when the finger pinch preventing device 10 is delivered or stored, the finger pinch preventing device 10 can be made compact.

  The finger pinching prevention device 10 may be modified so as to have various shapes, sizes and / or configurations so as to be adapted to various opening angles θ (see FIG. 2A) of the door main body 12 it can. FIG. 4 schematically shows the finger pinching prevention device 110 capable of corresponding to the opening angle θ from 0 ° (the angle when the door is closed) to 180 °. FIG. 4 (a) is a view when the door is closed, that is, when the opening angle is 0 °, and FIG. 4 (b) is a view when the opening angle θ is about 90 °. Is a view when the open angle θ is about 110 °, and FIG. 4 (d) is a view when the open angle θ is about 180 °. In order to correspond to these opening angles, in the finger pinch preventing device 110, unlike the finger pinch preventing device 10, connection tapes 24 are provided on both surfaces of the connecting portion 26 between the first strip 22a and the second strip 22b. Has been applied. Furthermore, in the finger pinch prevention device 110, as shown in FIG. 5, the first strip 22a and the second strip 22b are arranged with a predetermined gap S in the second direction D2. Thereby, the connection part 26 between the 1st strip 22a and the 2nd strip 22b can be suitably bent on either side. Similarly, the connection tape 24 is applied to both surfaces of the connection portion 26 between the third strip 22c and the fourth strip 22d, and a predetermined gap S is formed between the strips. Similarly, the connection tape 24 can be applied to both surfaces of the connection portion 26 between the second strip 22b and the third strip 22c, but the connection tape 24 is applied to only one surface. In the finger pinch prevention device 110, the connection tape 24 may be applied to only one side of all the connection portions 26 instead of the both sides. Further, the predetermined gap S may be determined in accordance with the thickness of the strip 22 and the movable range required for the connection portion 26.
