Description

Hinged door pivot front and back gap cover device

[0001] The present invention relates to a front-back gap cover device for a hinged door rotation axis to prevent safety accidents caused by fingers getting caught in the gap between a hinged door and a door frame that rotates around a hinge. More specifically, the invention relates to a front-back gap cover device for a hinged door rotation axis in which a first hard cover plate in a flat shape and a second hard cover plate in a curved shape are connected by a first soft joint piece, the first hard cover plate and a coupling member are connected by a second soft joint piece, the head portion of the coupling member is inserted into a hollow portion through an opening of a molding strip and coupled, and the second hard cover plate and a fixing plate are connected by a third soft joint piece.

[0002] Korean Utility Model Registration No. 20-0479978 (March 23, 2016) introduces a "gap cover for covering the gap between a door and a door frame."

[0003] The above gap cover is an attachment plate attached to the door frame and the door, respectively; The cover portion includes a plurality of hard plates stacked between the attachment plates, and a connecting soft portion comprising an outer soft portion connecting the outer ends of adjacent hard plates and an inner soft portion connecting the inner ends of adjacent hard plates, and expands and contracts in a zigzag pattern according to the opening and closing of the door. The hard plates connected to the attachment plates are connected by the outer soft portion located outside, at a position relatively far from the gap, rather than when connected by the inner soft portion, thereby preventing the hard plates directly connected to the attachment plates from spreading apart from the attachment plates. Furthermore, the width of the hard plates connected to the attachment plates is formed to be relatively shorter than the width of the attachment plates, so that the inner ends of the hard plates connected to the attachment plates are located inside the attachment plates, and even after the cover portion is deformed, the inner ends are supported in a state of close contact with the attachment plates, thereby preventing the hard plates directly connected to the attachment plates from spreading apart from the attachment plates, so that the cover portion is restored to its original zigzag state without getting stuck in the gap after deformation.

[0004] However, the above gap cover has a disadvantage in that when the door is open and the cover is pressed firmly with a hand, the cover can enter the gap between the doors along with the finger, and when the door is closed with the cover and finger in the gap in this manner, the finger gets caught in the door gap, and if the door is closed forcefully, the door may fall off.

[0005] Accordingly, the objective of the present invention is to provide a planar first hard cover plate and a curved second hard cover plate connected by a first soft joint piece, a first hard cover plate and a coupling member connected by a second soft joint piece, a head portion of the coupling member inserted into a hollow portion through an opening of a molding strip and coupled, and a second hard cover plate and a fixing plate connected by a third soft joint piece, so that when opening and closing a hinged door, the folding and unfolding motion of the first to third soft joint pieces is smooth, bends smoothly with little force, and operates without noise; the hinges do not tear even with repeated folding and unfolding, allowing for long-term use; and since the first and second hard cover plates continuously cover the front gap of the hinged door's rotation axis (hinge), the hard cover plates are not pressed even if the first and second hard cover plates are pressed by a finger, thereby fundamentally preventing a finger from getting caught in the front gap. It provides a front and back gap cover device for a hinged door pivot axis.

[0006] Another objective of the present invention is to provide a hinged door rotation axis front and back gap cover device in which a rigid cover is formed in a semi-cylindrical shape, and one end of a first soft cover and one end of a second soft cover are respectively connected to both sides of the rigid cover, the other end of the first soft cover is connected to a coupling member, the head portion of the coupling member is inserted into a hollow portion through the opening of a molding strip and coupled, and the other end of the second soft cover is connected perpendicularly to the side end of a fixing plate, so that when the hinged door is opened and closed, the bent portions of the first and second soft covers are deformed so as not to interfere with the opening and closing of the hinged door, and the rigid semi-cylindrical rigid cover covers the hinged door rotation axis (hinge) and the back gap, so that even if the rigid cover is pressed with a finger, the rigid cover is not pressed, thereby fundamentally preventing a finger from getting caught in the back gap.

[0007] An example of a front-to-back gap cover device for a hinged door rotation shaft according to the present invention for achieving the above-mentioned purpose is,

[0008] A first hard cover plate in a flat shape and a second hard cover plate in a curved shape are connected by a first soft joint piece, a connecting piece between the first hard cover plate and a coupling member is connected by a second soft joint piece, a head portion of the coupling member is inserted into a hollow portion through an opening of a strip and coupled, and a second hard cover plate and a fixing plate are connected by a third soft joint piece.

[0033]

[0034] Referring to FIGS. 1 and 2, in the first embodiment of the present invention, a hinged door rotation axis front-back gap cover device is formed such that a first hard cover plate (110) in a flat shape and a second hard cover plate (120) in a curved shape are connected by a first soft joint piece (130), a connecting piece (161) of the first hard cover plate (130) and a coupling member (160) are connected by a second soft joint piece (140), a head portion (163) of the coupling member (160) is fitted into a hollow portion (184) through an opening (185) of a strip (180) and coupled, and the second hard cover plate (120) and a fixing plate (170) are connected by a third soft joint piece (150).

[0035] The first hard cover plate (110), the second hard cover plate (120), the first to third soft joint pieces (130, 140, 150), the connecting member (160), and the fixing plate (170) are connected to each other during the process of forming by an extrusion molding method.

[0036] The first and second hard cover plates (110, 120) are formed of a hard plastic material such as hard PVC, so they are not compressed even when an external force is applied.

[0037] The first soft joint piece (130) is formed from a soft plastic material such as soft PVC, and the first and second connecting parts (132, 133), which are formed stepwise on both sides of the body part (131), are joined by heat and pressure generated during the extrusion molding process while overlapping with the left connecting part (111) of the first hard cover plate (110) and the right connecting part (121) of the second hard cover plate (120), respectively, and the thickness (t1) of the body part (131) is formed to become thinner towards the center.

[0038] The first soft joint piece (130) configured as described above is formed from a PVC material such as the first and second hard cover plates (110, 120), so that they are well bonded together during the extrusion molding process, and the bonding of the first and second connecting parts (132, 133) after extrusion molding is not easily separated by external force, and the thickness (t1) of the body part (131) is formed to become thinner toward the center, so that the folding and unfolding motion is smooth, it bends smoothly with little force, and it can be operated without noise, and the body part (131) does not tear even if the folding and unfolding is repeated.

[0039] The above second and third soft joint pieces (140, 150) have the same composition as the first soft joint piece (130).

[0040] Referring to FIGS. 3 and 4, the connecting member (160) has a neck portion (162) formed perpendicularly to the connecting piece (161) at the center of one side of the connecting piece (161), a rhombus-shaped head portion (163) formed at the tip of the neck portion (162), and a cut groove (164) formed from the tip of the head portion (163) to the center.

[0041] The above-mentioned strip (180) has a vertical section (182) that is bent vertically at the end of a joint section (181) where double-sided tape (189) is adhered to the outer surface, and a horizontal section (183) that is bent at a right angle at the tip of the vertical section (182), so that the horizontal section (183) is arranged parallel to the joint section (181), thereby forming a square-shaped hollow section (184) by the joint section (181), the vertical section (182), and the horizontal section (183), and an opening (185) is formed between the joint section (181) and the horizontal section (183), and a pair of stopper tabs (186, 187) are arranged facing each other at both ends of the opening (185), a guide section (181a) extends from the joint section (181) toward the opening (185), and a support section (188) is vertically formed in the middle of the horizontal section (183). It is formed.

[0042] The above-mentioned stopper (186, 187) is formed in the shape of a right triangle, so that the diameter of the opening (185) becomes narrower from the entrance towards the inside due to the stopper (186, 187).

[0043] The above support member (188) should be set to a height that does not interfere with closing the hinged door and can support the first hard cover plate (110) when the hinged door is opened.

[0044] With the above configuration, the connecting member (160) has a rhombus-shaped head portion (163) inserted into the hollow portion (184) through the opening (185) of the strip (180) in the direction of the arrow (165), as shown in FIG. 3. At this time, as the gap of the cut groove (164) formed in the head portion (163) narrows, the diameter of the head portion (163) becomes smaller, allowing the head portion (163) to pass through the opening (185). As the head portion (163) that has passed through the opening (185) is restored to its original state, the head portion (163) catches on a pair of catch tabs (186, 187) formed on both sides of the opening (185), thereby preventing the head portion (163) from coming out of the hollow portion (184).

[0045] And, when the head portion (163) is placed in the hollow portion (184) of the strip (180), if the head portion (163) is forcibly pulled in the direction of the arrow (166) of FIG. 4, the gap of the cut groove (164) formed in the head portion (163) narrows, and the diameter of the head portion (163) becomes smaller, so that the head portion (163) is separated through the opening (185).
