Description

Safety door for preventing hand from being pinched

Technical Field

The present utility model relates to a pinch-proof safety door in which a pinch-proof buffer plate is provided at a space portion formed between a door frame and a door panel rotatably coupled by a hinge member, thereby preventing a safety accident caused by a user's body such as a HAND (HAND).

Background

In general, the inside and outside of a building structure are isolated from each other and divided into different spaces by a plurality of inner walls so that it is possible to live while maintaining privacy, and a door of a push-pull type is provided so as to be movable from inside to outside or from outside to inside and between the inner spaces.

One side of the door is openably fixed to a door frame supported by a wall body by a hinge or a hinge, and a handle is provided at a portion opposite to the portion fixed by the hinge or the hinge, so that the door can be opened and closed by pulling or pushing the handle.

Because the door is rotatably coupled to the door frame by the hinge, the door opening and closing process can be easily performed, but sometimes it may happen that a child's finger is caught between the door frame and the door in a state in which the door is opened, and if the door is closed in a state in which the situation is not recognized, the finger receives a great pressing force due to the edge of the closed door and thus causes finger injury.

As a solution to the above-described problems, a safety member for a door is proposed in korean laid-open patent publication No. 20-371704, which can prevent the occurrence of safety accidents such as pinching of a finger between a door frame and a door when opening and closing the door in advance by combining a semicircular safety member extrusion-molded or injection-molded using a metal or synthetic resin with a side surface of a safety door such as a gate or a fire door, but can be used only in a state that hinges for opening and closing the door are respectively coupled to upper and lower portions of the door frame, and cannot be used in a state of being located at an intermediate height between the door and the door frame.

Moreover, since the inside of the semicircular safety member is in a filled state, the pressurizing force thereof cannot be sufficiently relieved in the case where the fingers of the child are caught.

Further, in korean laid-open patent publication No. 20-426894, there is proposed a sliding door for preventing finger pinching accidents and opening and closing noise, which is provided with an anti-pinching elastic member having a scraping line in an anti-pinching groove formed in a door panel, so that the impact buffering efficiency generated at the time of collision of the sliding door with a door frame is improved while satisfying the demand for aesthetic appearance, but is provided only at a portion located between hinges, and cannot pass through the hinges and cover all portions between the door frame and the sliding door.

First embodiment

As shown in fig. 1 and 2 (sectional views A-A' in fig. 1), the safety door 1 according to the present utility model generally includes a door frame 100, a door panel 200, a HAND pinching prevention buffer plate 10, and a hinge member 500, and by the organic coupling constructed as described above, when opening and closing in a state in which a body such as a HAND (HAND) of a user who needs to open the door is pinched between the door frame 100 and the door panel 200 at a spacing portion S, the occurrence of a safety accident due to pinching can be prevented.

Specifically, as shown in fig. 2, the anti-pinching buffer plate 10 is installed at a spacing portion S forming a spacing of about 30 to 35mm from the door frame 100 when the door panel 200 is in a "closed" state, so that a pinching phenomenon can be prevented by shielding the spacing portion S from the outside, and also when a body is brought into a state of being opened into a slit form by opening the door panel 200 inside the spacing portion S, the body is subjected to an external force such as an angle due to the rotation of the door panel 200, the shape can be changed by means of an elastic force according to the external force and thereby the occurrence of a safety accident can be prevented, including the frame member 300 and the tension portion 400.

For example, the frame member 300 is a structure for mounting the tension part 400 to the door panel 200, and includes a frame body 310 and a protrusion 315.

The frame body 310 is made of a HARD (HARD) synthetic resin material or a metal material, and as shown in the drawing, is formed in a plate shape as a whole, and a protrusion 315 for being shape-fittingly and detachably fastened to the coupling groove 413 of the first tension body 411 is formed at a center portion compared with an area.

Meanwhile, coupling members 313 to which the second tension body 421 is detachably coupled are formed at both sides of the frame body 310.

A plurality of fastening holes 311 adjacent to each other are perforated in the outer side surface of the frame body 310 in the length direction so that they can be fixedly coupled with each other with the door panel 200 by means of fastening members P such as bolts or screws.

In this case, depending on the coupling position of the hinge member 500 attached to the door panel 200, it is preferable to attach a plurality of frame bodies 310 to the door panel 200 so as not to interfere with the function of the hinge member 500.

As shown in fig. 4, the frame body 310 of the present utility model may be provided with a mounting plate 320 having an outer surface coupled in a detachable sliding manner, so that the anti-pinching buffer plate 10 mounted to the door panel 200 can be more easily maintained.

The mounting plate 320 may have other fastening holes formed at positions opposite to the fastening holes 311, through which the fastening members P are inserted, and buckling portions 321 having a predetermined diameter slidably coupled to the guide protrusions 317 formed on the outer side surface of the frame body 310 formed on both sides thereof.

Thereby, the worker can couple the guide protrusions 317 formed on both sides of the frame body 310 to the pair of buckling portions 321 that can be attached to and detached from the entire frame body 310 equipped with the tension portion 400 after first attaching the attachment plate 320 to the outer side surface of the door panel 200 by means of the fastening assembly P.

In addition, the tension part 400 is made of an elastically resilient material, and prevents the spacer S from being exposed to the outside in the "closed" state of the door panel 200 by being detachably coupled to the frame body 310, or from being damaged by external force pressurization by means of its elastic force according to the shape of the body entered into the spacer S, thereby preventing the corresponding body from being damaged, including the first tension member 410 and the second tension member 420.

The first tension member 410 is detachably coupled to the frame body 310 and prevents the body, which is entered into the inside of the spacer S, from being damaged when the door panel 200 is opened and closed by means of an elastic force, including the first tension body 411 and the coupling groove 413.

The first tensile member 411 is formed in a tubular (PIPE) shape of a predetermined length as shown in the drawing, and is made of an elastically-recoverable synthetic resin material, and is made of a flexible material having a relatively weak strength as compared with the second tensile member 421.

First ridges 415 having a predetermined inclination angle are formed on both sides of the first tensile body 411 to be in surface contact with the second tensile body 421 or to be adjacent to each other, so that when the first tensile body 411 is subjected to an external force of the door panel 200 due to the body being clamped and is changed in shape (e.g., twisted), the first ridges 415 are pushed by the external force after being in surface contact with the second ridges 425 of the second tensile body 421 and the second tensile body 421 is separated from the coupling member 313, thereby further maximizing the effect of preventing body injury (refer to fig. 5).

A coupling groove 413 for being detachably coupled to the protrusion 315 of the frame body 310 is formed at an outer side surface of the first tension body 411, whereby maintenance of the first tension body 411 can be easily performed.

Further, the second tension member 420 can prevent the body from entering the space S to the maximum extent by shielding the space S from the outside, while being separated from the frame body 310 by means of the external force when the shape of the first tension body 411 is changed due to the body pinching phenomenon and further maximizing the effect of preventing the body from being injured, including the second tension body 421 and the film member 427.

As shown in the drawing, the second tension member 421 has one side surface adhered to both sides of the inner side surface of the film member 427, and an insertion groove 423 detachably coupled to the coupling member 313 is formed in the other side surface, and is made of a material having a higher strength than the first tension member 411, so that it can be used for a long time even in the case of frequent disassembly.

On the outer side surfaces of the second tensile body 421 opposite to the first ridge 415, a second ridge 425 having the same inclination angle as the first ridge 415 is formed, so that the first ridge 415 is pushed by an external force after being in surface contact with the second ridge 425 when the first ridge 415 is changed in shape by means of an elastic force, and thereby the fitting groove 423 is separated from the coupling member 313.

The film member 427 is formed in a plate shape using a synthetic resin material that can be easily bent and unfolded, and wraps the outer side surface of the first tensile member 411.

A pair of second tension bodies 421 are adhered to both sides of the film member 427, and the same pattern as that of the door panel 200 or the outer side of the door frame 100 is printed on the outer side, and particularly, the spacer S can be shielded from the outside in a state where the door panel 200 is "closed", thereby preventing the body from being pinched.

Thereby, even after the second tension body 421 is separated from the coupling member 313, the second tension body 421 can be maintained in a state of being adhered to the film member 427, thereby preventing loss and being easily recombined.

Second embodiment

As shown in fig. 1 and 6 (sectional views A-A' in fig. 1), the safety door 1 according to the present utility model generally includes a door frame 100, a door panel 200, a HAND pinching prevention buffer plate 10, and a hinge member 500, and by the organic coupling constructed as described above, when opening and closing in a state in which a body such as a HAND (HAND) of a user who needs to open the door is pinched at a spacing portion S between the door frame 100 and the door panel 200, it is possible to prevent occurrence of a safety accident due to pinching.

Specifically, as shown in fig. 6, the anti-pinch buffer board 10 is installed at a spacing portion S forming a space of about 30 to 35mm with the door frame 100 when the door panel 200 is in a "closed" state, so that a pinching phenomenon can be prevented by shielding the spacing portion S from the outside, and also when a body is brought into a state of being opened into a slit form by opening the door panel 200 inside the spacing portion S, the body is subjected to an external force such as an angle due to the rotation of the door panel 200, the shape can be changed by means of an elastic force according to the external force and thereby the occurrence of a safety accident, including the frame member 300 'and the tension portion 400', can be prevented.

For example, the frame member 300 'is a structure for mounting the tension part 400' to the door panel 200, and includes a frame body 310 'and a first protrusion 320'.

The frame body 310 'is made of a HARD (HARD) synthetic resin material or a metal material such as aluminum, and may be inserted into a coupling body 420' to be described later by forming the whole thereof into a plate shape as shown in the drawing.

A groove portion 311 'is formed along a length direction at an outer side surface of the frame body 310', that is, a surface facing each other with the coupling body 420', so that a fastening member P such as a bolt or a screw is inserted through a fastening hole of a long hole form (refer to an enlarged sectional view in vertical and horizontal directions of fig. 8) through an inner side of the groove portion 311' and thereby the frame body 310 'and the door panel 200 are coupled to each other, and it is possible to prevent the frame body 310' mounted to the door panel 200 from being influenced by a force pushing in a left-right direction as compared with a shape of a corresponding fastening member formed in a column shape.

Thereby, it is possible to prevent the heads of the respective fastening assemblies P from protruding to the outside of the frame body 310 'in a state where the door panel 200 and the frame body 310' are coupled to each other by means of the fastening assemblies P, thereby preventing direct contact with the coupling body 420 'described later and thereby preventing damage to the coupling body 420'.

Meanwhile, the other side of the frame body 310' having the groove portion 311' formed at one side, i.e., the outer side surfaces facing each other with the door panel 200, is formed with a plurality of concave portions 313' at the same interval therebetween, and the concave portions 313' may minimize a contact area when the frame body 310' and the outer side surfaces of the door panel 200 are in surface contact with each other, thereby minimizing damage to the corresponding door panel 200 when being detached from each other.

The first protrusions 320 'are formed at both sides of the frame body 310' in a symmetrical manner to each other, and contact with outer sides of the second protrusions 423 'formed at both sides of the coupling body 420' when the frame body 310 'is inserted and mounted to the inside of the coupling body 420' to be described later, so that the frame body 310 'and the coupling body 420' are insertedly coupled to each other.

At this time, an arc-shaped first curved surface portion is formed at the outer side of the first protrusion portion 320' in order to more easily insert the frame body 310' into the inside of the coupling body 420 '.

In addition, the tension part 400' is made of an elastically resilient material, and prevents the spacer S from being exposed to the outside in the "closed" state of the door panel 200 by being detachably coupled to the frame body 310', or from being deformed according to the shape of the body entered into the spacer S by means of its elastic force, thereby preventing the corresponding body from being damaged by the pressurization by the external force, including the tension member 410', the coupling body 420', and the sheathing member 430'.

For example, the tension member 410' is made of a flexible synthetic resin material that can be elastically restored, and prevents the body that enters the inside of the spacer S from being damaged by an elastic force when the door panel 200 is opened and closed, including the curved surface portion 411' and the partition 413'.

As shown in the drawing, the tension member 410 'is formed in a tubular shape (PIPE) having a predetermined length along the vertical direction, and a coupling body 420' is adhered to one side, and an arc-shaped curved surface 411 'is formed along the longitudinal direction on the other side, as in the frame body 310'.

The curved portion 411' is formed in an arc shape to prevent the spacer S from being exposed to the outside in the state where the door panel 200 is "closed", and to prevent interference with the door frame 100 within the radius of rotation thereof when the corresponding door panel 200 is rotated to the "open" state.

Further, at least one partition 413' is formed inside the tension member 410' along the longitudinal direction so that inner sides of the tension member 410' facing each other are connected to each other, thereby maintaining the shape of the tension member 410', even when a user's body is pinched or the like is frequently occurred (see fig. 9).

In addition, the coupling body 420 'is made of a heavy polyvinyl chloride (PVC) material and is formed in a plate shape of a prescribed length in a vertical direction, and one side is formed with a flat surface to be in surface contact with the outer side of the tension member 410' by means of an adhesive or a later-described packing member 430', while the other side is provided for the frame body 310' to be inserted into the inside and to be coupled by being inserted.

For this, an insertion groove 429' into which the frame body 310' is inserted is formed at the other lateral inner side direction of the coupling body 420', and second protrusions 423' are formed at both sides so as to be in contact with and coupled with the first protrusions 320' formed at both sides of the frame body 310' inserted into the insertion groove 429 '.

Further, second curved portions facing each other with the first curved portions formed at the first protrusion 320' are formed at the outer sides of the second protrusion 423', so that the second curved portions are temporarily spread apart along the outer sides of the first curved portions by means of the elastic force of the coupling body 420' when the frame body 310' is inserted into the insertion groove 429' and then restored to the original state.

At this time, a pair of protruding portions 421' are formed so as to protrude adjacent to each other on the inner side surface of the coupling body 420' in which the insertion groove 429' is formed, that is, on the surface facing each other with respect to the groove portion 311' formed in the frame body 310' inserted into the insertion groove 429', so as to be in contact with the outer side surface of the frame body 310 '.

Meanwhile, as shown in the drawing, each of the protruding portions 421 'has a part of the outer side surface in surface contact with the frame body 310' and the remaining outer side surface facing the groove portion 311', so that the frame body 310' is inserted into the insertion groove 429 'together with the first and second protruding portions 320', 423 'in a shape-fittingly inserted and fixed in the insertion groove 429' without shaking.

Further, as shown in the drawings, the protrusion 421' may be formed with an inclined surface 425' inclined at one side of the protrusion surface as needed, thereby preventing a problem of a decrease in fixing force due to shaking of the frame body 310' inserted into the insertion groove 429', or an overall cross section of the protrusion 421' may be formed withThe additional protrusions 427 'are formed in a shape of a letter and are further formed in a protruding direction thereof to be inserted into the inside of the groove portion 311', thereby maximizing a fixing force between the frame body 310 'and the coupling body 420'.

The wrapping member 430 'is formed in a film shape made of synthetic resin, and wraps both the outer side surface of the coupling body 420' and the outer side surface of the frame body 310 'provided with the coupling body 420'.

Meanwhile, the overall aesthetic degree of the safety door 1 according to the present utility model can be enhanced by adopting the same shape as the surface shape (e.g., wood grain shape) of the door frame 100 or the door panel 200 at the outer side of the packing member 430', and particularly, the spacer S can be shielded from the outside in a state where the door panel 200 is "closed", thereby preventing the body from being pinched.

Third embodiment

First, as shown in fig. 1 and 10 (sectional views of A-A' in fig. 1), the safety door 1 according to the present utility model generally includes the door frame 100, the door panel 200, the anti-pinching buffer plate 10, and the hinge member 500, and by the organic coupling constructed as described above, when opening and closing in a state in which the body such as the HAND (HAND) of the user who needs to open the door is pinched between the door frame 100 and the door panel 200, the occurrence of a safety accident due to pinching can be prevented.

Specifically, as shown in fig. 10, the anti-pinching buffer plate 10 is installed at a spacing portion S forming a spacing of about 30 to 35mm from the door frame 100 when the door panel 200 is in the "closed" state, so that a pinching phenomenon can be prevented by shielding the spacing portion S from the outside, and also when a body is applied with an external force such as an angle due to the rotation of the door panel 200 in a state in which the body is entered into the inside of the spacing portion S opened in a slit form by opening the door panel 200, the shape can be changed by means of an elastic force according to the external force and thereby the occurrence of a safety accident can be prevented, including the tension portion 400.

For example, the door panel 200 includes a recess 210 to mount the tension portion 400″ to the door panel 200.

The recess 210 is formed on the side of the panel 200 opposite to the door frame 100, so that the panel can be inserted into a coupling body 420″ described later.

The coupling body 420″ may be coupled to the door panel 200 by inserting the protrusion 423″ in an embedded state inside the recess 210 formed in the longitudinal direction on the outer side of the door panel 200, that is, the side opposite to the coupling body 420″.

The protrusions 423 "are formed in a symmetrical manner to each other at both sides of the door panel recess 210 and contact with outer sides of the protrusions 423" formed at both sides of the coupling body 420 "when the door panel recess 210 is insert-mounted to the inside of the coupling body 420" described later, thereby allowing the door panel 200 and the coupling body 420 "to be insert-coupled to each other.

In addition, the tension part 400 'is made of an elastically resilient material, and prevents the spacer S from being exposed to the outside in the "closed" state of the door panel 200 by being detachably coupled to the door panel 200, or from being deformed according to the shape of the body entered into the spacer S by means of its elastic force, thereby preventing the corresponding body from being damaged by the pressurization by the external force, including the tension member 410', the coupling body 420 ', and the sheathing member 430'.

For example, the tension member 410″ is made of a flexible synthetic resin material that can be elastically restored, and prevents the body that enters the inside of the spacer S from being damaged by an elastic force when the door panel 200 is opened and closed, including the curved surface portion 411″ and the partition 413".

As shown in the drawing, the tension member 410 "is formed in a tubular shape (PIPE) having a predetermined length along the vertical direction, and has a coupling body 420" adhered to one side and an arc-shaped curved surface 411 "formed along the longitudinal direction on the other side, similarly to the door panel 200.

The curved surface 411″ is formed in an arc shape to prevent the spacer S from being exposed to the outside in the closed state of the door panel 200, and to prevent interference with the door frame 100 within the rotation radius thereof when the corresponding door panel 200 is rotated to the open state.

Further, at least one partition 413″ is formed in the inside of the tension member 410″ along the longitudinal direction so that inner sides of the tension member 410″ facing each other can be connected to each other, thereby maintaining the shape of the tension member 410″ even when a user's body is pinched or the like frequently occurs (see fig. 13).

In addition, the coupling body 420 ' is made of a heavy polyvinyl chloride (PVC) material and is formed in a plate shape having a prescribed length in a vertical direction, and one side is formed with a flat surface to be in surface contact with an outer side of the tension member 410 ' by means of an adhesive or a later-described packing member 430 ', while the other side is provided with a recess portion of one side of the door panel 200 inserted into the inside and coupled by being inserted.

For this, an insertion groove 429 "into which the door panel 200 is inserted is formed at the other lateral inside direction of the coupling body 420", and the protrusions 423 "are formed at both sides so as to contact and couple with the concave portions 210 formed at both sides of the door panel 200 inserted into the insertion groove 429".

Meanwhile, the coupling body 420″ formed at the tension part 400″ contacting and coupled with one side of the door panel 200 may allow the concave parts 210 formed at one side of the door panel 200 facing each other to be inserted into the insertion grooves 429″ and the coupling body 420″ may be restored to the original state after being temporarily expanded by means of elastic force.

The wrapping member 430″ is formed in a film shape made of synthetic resin, and wraps the outer surface of the joined body 420″.

Meanwhile, the overall aesthetic degree of the safety door 1 according to the present utility model can be enhanced by adopting the same shape as the surface shape (e.g., wood grain shape) of the door frame 100 or the door panel 200 at the outer side of the packing member 430″, and particularly, the spacer S can be shielded from the outside in a state where the door panel 200 is "closed", thereby preventing the body from being pinched (refer to fig. 14).

In the first to third embodiments described above, the hinge member 500 may be fastened to the door frame 100 and the door panel 200 without interfering with the function of the anti-pinch buffer board 10, as shown in fig. 15 to 17, so that the door is opened and closed by the rotation of the door panel 200, and either the first hinge 510 or the second hinge 520 is used.

For example, as shown in the figure, the first hinge 510 includes a pair of hinge pieces 511 and a rotation shaft 515, and is provided in plurality in the space S.

A pair of curved sheets 511 respectivelyThe zigzag shape is folded and disposed opposite to each other, and one of them is fastened to the outer side surface (surface on which the frame body is mounted) of the door panel 200 and the other of them is fastened to the door frame 100 by fastening means, thus, the pair of integers is installed in a shape in such a manner that the interval D1 corresponding to the area of the interval S is formed, so that the area of the interval S and thus the shape of the anti-pinch buffer plate 10 can be maintained even in a state where the safety door 1 according to the present utility model is closed, i.e., the door panel 200 is "closed".

A rotation hole 513 is formed on the surfaces of the pair of bent pieces 511 facing each other so as to rotatably connect the pair of bent pieces 511 to each other by respectively penetrating the insertion rotation shaft 515, and the rotation holes 513 are arranged to overlap each other in a vertical direction so as to be connected to each other by the rotation shaft 515.

The second hinge 520 includes a pair of pivot bodies 521 and a rotation shaft 525 rotatably coupled to each other, and the area of the spacer S is maintained by attaching a plurality of the second hinge to the safety door 1.

The pivot bodies 521 are formed in a predetermined length, and the rotation holes 523 formed at one side are arranged to overlap each other in the vertical direction as the rotation holes 513, so that the pair of pivot bodies 521 are rotatably connected to each other by inserting the rotation shaft 525 therethrough.

Wherein one of the pivot bodies 521 is coupled to the outer side of the door frame 100 by means of a fastening assembly P, and the other is fastened to the door panel 200 by means of a corresponding fastening assembly P, so that the door panel 200 is rotated about the rotation axis 525.

In this case, as shown in the drawing, the length D2 of each pivot body 521 is preferably formed so that the area of the spacer S is kept constant around the rotation shaft 525 in a state where the pair of pivot bodies 521 are connected by the rotation shaft 525, and the pair of pivot bodies 521 fastened to the door panel 200 or the door frame 100 may be formed in different lengths as needed so as to satisfy the area of the spacer S (see fig. 16 and 17).

As described above, the safety door 1 according to the present utility model adopts a structure in which the anti-pinch buffer plate 10 is provided on the spacing portion S between the door frame 100 and the door panel 200 rotatably coupled to each other by means of the hinge member 500, unlike the conventional manner, so that the phenomenon of being pinched can be prevented by shielding the corresponding spacing portion S from the outside, and even when a body such as a user 'S HAND (HAND) is pinched and is applied with an external force due to the corresponding door panel 200, a shape change can be achieved by means of the elastic force of the elastic restoring tension portions 400, 400', 400″ so as to alleviate the pressurizing force and prevent the occurrence of safety accidents.

In addition, unlike the conventional method, the first hinge 510 or the second hinge 520 is installed to maintain the area of the space S provided with the anti-pinching buffer plate 10 when the door is opened and closed by the rotation of the door panel 200, so that the anti-pinching buffer plate 10 can be prevented from being damaged and the aesthetic appearance thereof can be improved.
