Description

A protection apparatus to prevent a finger wizard in side hinged doors

The present invention relates to a hand pinch prevention device for a side hinged door, and more specifically, a door frame on which a door is mounted, and a side surface for preventing hand pinching in the opening gap of the door in a door with a hinge on the side of the door. It relates to a hand pinch prevention device of a hinged door.

In the case of a door made of steel or wood, in the case of a door made of steel or wood, a hinge is mounted between the door frame fixed to the building structure and the side of the door installed in the door frame so that it can be rotated. It is installed and fixed at the top and bottom of the door and is configured to be rotated open by the vertical axis center by attaching hinge shafts at the top and bottom between the hinge plate for fixing the glass door and the door frame.

In the case of a hinge mounted on the door frame and the side of the door, butterfly-typed hinges having hinge plates for mounting and fixing the door frame and the door on both sides around the hinge axis (hereinafter referred to as'hinge') .) is widely used.

Doors in apartment houses or houses, especially entrance doors, are mounted to be able to open and close by a hinge mounted on the side of a relatively strong shape, that is, a door made of steel or wood having a little thickness.

Therefore, the door is opened in an opening and closing method with the hinge as the center, so that an open rotation gap is generated between the side of the door and the door frame when it is rotated, and there are frequent cases of injuries due to the fingers of a person entering the open rotation gap.

As a safety device to solve this problem, a door stopper is installed between the door and the door frame to smooth the door opening and closing speed.However, if time elapses after installation, the door stopper leaks or adjusts the hydraulic pressure. The door is rapidly opened or closed due to the fact that the initial setting of the door stopper cannot be performed due to rotation of the screw, etc., and in this case, the injury caused by the pinching of the fingers becomes very serious. In particular, an accident occurs in the case of infants with low attention. The frequency of is very high.

As the above-described problems have emerged, in recent years, in the case of apartment houses such as apartments, it is a situation that it is mandatory to install a safety device that fundamentally prevents injuries such as finger pinching by closing the hinge mounting part between the door frame and the door. Various types of hand pinch prevention devices or safety devices have been devised for this purpose.

Another problem to be considered in configuring a safety device for preventing hand jamming relates to the shape of the door.

When the hinge (c) is mounted between the door frame (a) and the side of the door (b) as shown in Fig. 1a, the rotational gap in an arc shape when the hinge (c) is rotated open and closed ( When g1) occurs and only this rotation gap (g1) is shielded, a safety device is formed.

In the case of a glass door as shown in FIG. 1B, a hinge plate (d) is separately provided above and below the door (b1) mounted on the door frame (a1) to restrain the upper and lower sides of the door (b1), and this hinge A hinge axis (c1) is provided between the plate (d) and the door frame (a1) on the top and forward sides, so that it is rotated and opened around the hinge axis (e), so that the door frame (a1) and the door (b1) rotate. An open gap g2 and a rotation gap g3 that are completely open when opened are additionally formed to form a relatively large open rotation gap.

Therefore, in the case of a glass door, unlike a general door of the shape of FIG. 1A, the opening rotation gap is relatively wide, and the geometrical deformation state of the trajectory formed by the side end of the door upon opening becomes complicated.

In consideration of these points, the material or mounting mode of the door must also be considered, and a safety device must be designed.

The hand pinch prevention device of the side hinge-mounted door of the present invention in consideration of the above-described aspects is suitable to be applied to a'side hinge-mounted door' in which a plurality of hinges are mounted between the door frame and the door side as shown in FIG. 1A. It relates to the provision of configuration.

Although there are member numbers that overlap with the description of the above-described known article and the member number disclosed in the sailor's patent document, the description of the known article and the member number of the sailor's patent document are ignored, and the description is followed by the member number of the present invention. Add the member number.

As shown in FIG. 1A, the hand grip prevention device of the side hinge-mounted door of the present invention provides a configuration suitable for application to a'side hinge-mounted door' in which a plurality of hinges are mounted between the door frame and the door side.

The present invention will be described with reference to the cross-sectional view of FIG. 2 and the following drawings of the present invention.

The hand pinch prevention device 100 of the side hinge-mounted door of the present invention includes a plurality of (usually 2 to 3) mounted by door plates 91 and 92 between the door frame 1 and the side of the door 10 installed on the building structure. Dog) butterfly-shaped hinge (90 in Fig. 5) to shield the inside and outside in the vertical direction,

An inner prevention hole 50 mounted between the door frame 1 and the door 10 on the indoor side, and an outer prevention hole mounted between the door frame 1 and the door 10 on the outdoor side (the hinged side) It is classified as (80).

The inner prevention hole 50 is to prevent hand jamming at the indoor side when the door 10 is opened and closed, and the outer prevention hole 80 prevents hand jamming at the hinge and rotation gap at the outdoor side when the door 10 is opened and closed. It is to do.

Inner prevention device 50, as in the configuration of the preferred conventional free technology described above,

It constitutes a member that is extruded into an elongate shape in the vertical direction, and a parking closing plate 51 having a long length in the width direction and a secondary blocking plate 52 having a relatively short length compared to the parking closing plate 51 are outlined in a triangle. It has a shielding operation plate part 55 integrally connected to the plate heat connection part 53 in the upper direction (△), and the parking closing plate 51 and the sub-shielding plate 52 cooperate with each other as a shielding plate for preventing actual hand jamming. Works.

The secondary shielding plate 52 is driven by driving the parking closing plate 51, and by making the length in the width direction different, the inner prevention hole toward the door frame 1 when the door 10 is closed due to geometric constraints. By pushing (Bias) (50) and making it close, the aesthetics are enhanced.

As shown in Fig. 5, the plate heat connection part 53 connecting the parking closing plate 51 and the sub-shielding plate 52 that is integrally extruded is formed on both sides or one side depending on the shape of the mold during the extrusion molding of the member. By providing a bending line 53-1 in which the side (one side in the drawing) is recessed, a bending line in the vertical direction is formed so that the parking closing plate 51 and the secondary blocking plate 52 are opened and closed when the door 10 is opened and closed. Make this easy to bend,

As with the components of a conventional sailor, only the plate heat connection 53 is separately composed of a soft material, and the parking closing plate 51 and the secondary shielding plate 52 separately molded by extrusion, etc. are joined together to form the shielding operation plate part 55 ) Can be formed to facilitate bending, but it is not necessary because the elasticity of the shielding operation plate part 55 itself, which is extruded out of soft plastic, exists.

As shown in order to connect the shielding operation plate 55 to the door 10 and the door frame 1, in addition to the shielding operation plate part 50, the inner prevention device 50 At both ends of the shielding plate 51 and the sub-shielding plate 52, it is a hollow body having a'circular' cross section, and is partially opened in the longitudinal direction of the shielding plate, and the hinge body 60-1 of the link hinge 60 to be described later is inserted. The hinge ball receiving holes (51-1, 52-1) having the bar insertion grooves (51-1', 52-1') as open grooves are also extruded integrally with the shielding operation plate (55) to form an elongated length. It is constructed continuously in the direction.

The inner preventing device 50 further includes a frame bracket 56 for mounting the shielding operation plate 55 to the door frame 1 and a door bracket 57 for mounting on the door 10.

As shown, the frame bracket 56 is a plate-shaped extruder, which is a vertical plate body, the mounting surface portion 56-1 and one end portion of the mounting surface portion 56-1, which is also a'circular' pipe body, and the upper side (parking shield). The hinge ball receiving hole 56- which is partially opened to the end side of the plate 51) and the bar insertion groove 56-2' into which the hinge body 60-1 of the link hinge 60 to be described later is inserted is opened. 2) is integrally extruded,

The door bracket 57 has a schematic cross-section "a" shape, and is a hole body having a cross-section'circular' at the mounting surface 57-1 to the door 10 and one free end, and the hinge of the link hinge 60 to be described later It integrally has a hinge ball receiving hole 57-2 having a bar insertion groove 57-2' into which the body 61 is inserted as an opening groove in the operating direction.

In the above, the frame bracket 56 is a flat member, and the door bracket 57 has a cross-section "a" shape. The secondary shielding plate 52 of the shielding operation plate part 55 is attached to the door frame 1 On the other hand, when the door 10 is opened, it rotates only at a small angle, so that the amount of rotational deformation is absorbed only by the elasticity of the hinge bar 61 of the link hinge 60 to be described later, but the door bracket 57 ) To rotate 90 degrees or more by the actual rotation of the link hinge (60), in particular the hinge bar (61), which will also be described later to change the geometric shape of the parking closing plate 51 according to the rotation. To allow.

The frame bracket 56 and the door bracket 57 are also elongated strap-shaped members that are continuous in the up and down directions along the door 10, and the mounting surface 56-1 of the frame bracket 56 and the door bracket ( The mounting surface portion 57-1 of 57) is attached to the door 10 and the door frame 1, and the rear surface thereof is adhered or screwed (not shown) to be perpendicular to the door 10 and the door frame 1, respectively. Is fixed.

The main components for forming the shielding part by connecting the shielding operation plate part 55 of the inner prevention device 50 with the frame bracket 56 and the door bracket 57 is a link hinge 60 shown.

The illustrated link hinge 60 is also extruded as an elastic synthetic resin, and as shown in FIG. 4, a long elongated strap body has a link bar 61 formed in a narrow width as a flat portion at the center of the cross-section. At both ends of the bar 61, hinge balls 62-1 and 62-2 having a circular cross section are integrally formed.

Therefore, the cross-section of the entire link hinge 60 has a roughly'Dumbbell shape', and due to this shape, the parking closing plate 51 and the secondary blocking plate 52 generated when the door 10 is opened and closed. ) Of the elastic material link hinge 60, in particular, the hinge bar 61 is bent as shown in FIG. 6 and added to the geometrical deformation of the parking closing plate 51 and the sub-shielding plate 52 Therefore, it absorbs the amount of deformation by microelastic deformation.

The coupling of the inner prevention hole 50 is the hinge ball receiving hole 51-1, 52-1 at both ends of the parking closing plate 51 and the secondary shielding plate 52 of the shielding operation plate portion 55, and the bar insertion groove ( 51-1', 52-1') and,

Ball receiving hole 56-2 and bar insertion groove 56-2' of frame bracket 56, hinge ball receiving hole 57-2 and bar insertion groove 57-2' of door bracket 57 It is made simply by sliding the hinge balls 62-1 and 62-2 and the hinge bars 61 at both ends of the link hinge 60 from above the longitudinal end of the slide.

This assembly configuration is shown in Fig. 7 and in the case where the clearance width between the door frame 1 and the ceiling is narrow, the configuration of the link hinge 60 of the elongate strap body can be flexibly inserted, so it is very useful.

This coupling configuration is clearly shown in FIG. 5.

With this configuration, when the door 10 is opened with respect to the door frame 1 with the hinge as the center of the axis, the door bracket 57 is rotated and the parking closing plate 51 by the link hinge 60 connected thereto. The hinge ball receiving hole (51-1) of the link hinge (60) and the hinge ball (62-1) of the link hinge (60) are operated and elastically deformed to pull the parking closing plate (51) while absorbing the geometrical deformation amount of its trajectory. ,

The secondary shielding plate 52 integrally connected to the parking closing plate 51 is rotationally deformed by the link hinge 60 connected to the frame bracket 56, but the hinge ball receiving study (56-2) of the frame bracket 56 The link hinge 60 constrained to absorbs the amount of rotational deformation of the secondary shielding plate 52 with only a slight elastic deformation.

Fig. 6 shows the open state.

The usefulness of the configuration obtained by varying the length of the parking closing plate 51 and the secondary blocking plate 52 in the width direction is similar to the conventional free technology, when the door 10 is closed,

When the parking closing plate 51 pushes the secondary shielding plate 52 toward the door frame 1 (by biasing), it bends the shielding operation plate 55 toward the door frame 1 and closes the door 10 when the door 10 is closed. There is a beautiful usefulness in appearance.

As another main component constituting the hand pinch prevention device 100 of the side hinge-mounted door of the present invention, there is an outer prevention device 80.

The outer prevention hole 80 is provided with a hinge 90 fixed to the door frame 1 by means of hinge plates 91 and 92 protruding from the outdoor side, and the gap between the door 10 and the door frame 1 To protect.

As shown in Fig. 3 or less, the outer prevention device 80 is a schematic cross-section "a" type attached to the door 10 side, the door attachment surface 81-1 to the door 10, and the other side free end The door bracket, which is an extrusion molding member that integrally has a hinge ball receiving hole 81-2 having a bar insertion groove 81-2' into which the hinge bar 60-1 of the hinge 60 of 81),

The outer shielding plate 82-1, which shields the dangerous part exposed to the outdoor side, is a synthetic resin plate made of elastic material having a roughly "U" cross-section, and one end of the outer shielding plate 82-1 (door frame 10 side) is free. It is an end, and the other end has a bar insertion groove 82-2' open to an open groove so that the hinge body 60-1 of the link hinge 60 is also inserted, like the inner prevention hole 50 described above. It has a hinge ball receiving hole (82-2).

The outer shield plate 82-1 and the door bracket 81 are also linked by a link hinge 60 and are fastened freely to rotate.

With this configuration, when the door 10 is opened, the outer shielding plate 82-1 connected to the door bracket 81 by the link hinge 60 changes the cross-sectional shape and the link bar 61 of the link hinge 60 It opens while absorbing the geometrical deformation elastically by the elastic deformation of

When the door 10 is closed, the exposed danger part is always shielded by deforming and restoring the outer shield plate 82-1 and the link hinge 60.

In the above, the hinge ball receiving hole (51-1, 52-1) at the ends of the parking closing plate 51 and the secondary shielding plate 52 of the inner prevention hole 50 and the hinge ball receiving hole of the frame bracket 56 (56-2) And, hinge balls (62-1, 62-2) of the link hinge (60) connecting the hinge ball receiving hole (57-2) of the door bracket (57),

The hinge ball receiving hole (81-2) of the door bracket (81) of the outer prevention hole (60) and the hinge ball receiving hole (82-2) of the shielding plate (82-1) of the outer shielding plate (82-1) When the hinge balls 62-1 and 62-2 of the link hinge 60 to be connected are joined by slide fitting,

In order to prevent the risk of flowing down the link hinge 60 due to long-term use and to increase the aesthetics, an adhesive may be applied during slide fitting, or as shown in FIG. 4 (only the upper part is shown). In the same way, forcibly fitting or bonding the end caps 65 that block and fix the ends at the top and bottom of the fastening part,

It would be preferable to screw it with a bolt (or a bolt-shaped synthetic resin molded body) having a thread not shown.

The hand pinch prevention device of the side hinge-mounted door of the present invention is assembled by detachment of the link hinge 60 from the shielding operation plate part 55 when the shielding operation plate part 55 is broken or cracked, etc. This is released so that it is possible to replace it with another shielding operation plate part 55 very easily, so that maintenance is simplified.
