Description

Automatic closing door system {AUTO CLOSING TYPE HINGE DOOR SYSTEM}

The present design is an automatic closing type door hinge that is effective in preventing damage to the rotating hinge member by mitigating the impact when the door is closed, a pivot support that can adjust the gap of the door, and a door jamb that can easily and correctly attach the design paper. It relates to a closed door system.

The so-called self-closing door hinge, which keeps the door open and closes automatically when the open door is lightly pushed, as described in Utility Model Registration No. 20-0246029, a fixed hinge member attached to one side of the threshold or the bottom of the doorway, It consists of a rotating hinge member attached to the bottom of the door so as to correspond to the fixed hinge member, and a vertical hinge shaft installed at the center of the fixed hinge member.

The fixed hinge member has an inclined surface at the top and the rotating hinge member has an inclined surface at the bottom, and the rotating hinge member rotates as the door is opened and closed, and the beveled surface slides up the beveled surface of the fixed hinge member, and then the bottom of the bevel on the rotating hinge member side. When the point reaches the apex of the inclined surface on the side of the fixed hinge member, the opening width is largest. Some self-closing door hinges allow the door to stay fully open.

This type of self-closing door hinge is mainly used for lightweight doors, such as toilet doors in buildings, rather than large doors, because there is a possibility that the movable hinge member may be damaged due to a large impact when closed.

Among them, as in Korean Patent Application Publication No. 10-2009-0038198, the lower fixed hinge member and the upper rotary hinge member are inserted into the hinge shaft so that the inclined surfaces thereof face each other, and a spring is loaded under the fixed hinge member and on the rotary hinge member. There are also things that mitigate the impact of the door opening and closing, but the weight of the door is limited, just like the previous self-closing door hinge.

It is proposed to overcome the weight limitation of the door is the automatic closing door hinge 1 of FIG. This self-closing door hinge (1) includes a fixed hinge member (2) and a bracket (3), a rotating hinge member (4) and a hinge shaft (5), a washer (6) and a spring (7), and a rear curtain washer (8). It is a combination of the nut (9) and the upper pivot (10).

In addition, a long bolt-type hinge shaft with a head is a shaft hole drilled in the center of the plane of the upper pivot (10), which is inserted into the pivot hole (B) formed on the bottom of the door frame (A) and supports the top of the door that opens and closes. (5) Lower the bracket (3) on the hinge shaft (5) that has passed through the upper pivot (10), a single-tubular fixed hinge member (2) with an inclined bottom (2a) and an inclined top (4a) The single tubular rotary hinge member (4) and the washer (6) and the spring (7) are inserted in sequence, and the washer (8) is inserted into the shaft end of the hinge shaft (5) exposed to the lower end of the spring (7). Ugo nut (9) is fastened.

The fixed hinge member 2 and the rotating hinge member 4 are molded hard synthetic resins in consideration of manufacturing cost reduction and wear resistance.

By adjusting the elasticity of the spring 7 pressing the rotating hinge member 4 with the tightening amount of the nut 9, the contact pressure of the rotating hinge member 4 with the fixed hinge member 2 is increased or decreased.

The self-closing door hinge (1) is fixed to the side frame (C) by placing a bracket (3) on the top of the side frame (C) that is attached by inserting the hinge side end of the door (D) and driving a piece. After fixing the end of the horizontal door frame (F) on one side of the top and bottom (C), the door plate is attached to the front and rear of the horizontal door frame (F) to complete the self-closing hinged door.

Reference numeral 12 denotes a lower pivot attached to the lower end of the side frame C, and 13 denotes a lower pivot support.

It looks at the pivot support for the lower pivot that is paired with the conventional self-closing door hinge. The lower pivot is mounted on the lower end of the door coaxially with the hinge axis of the self-closing door hinge, as is known, as in Patent Nos. 10-1458549 and 10-2018-0091592, the floor The pivot support attached to the pivot plate is made of a board with a perforated pivot plate hole and a pivot plate with a perforated pivot hole, and is stabilized by fastening a screw from the side after inserting the pivot plate into the pivot plate hole. It adjusts the deviation between the centers of

Since the pivot support of the prior art cannot adjust the height of the pivot plate, when installing the door on the door frame, for example, the door gap left between the entrance floor of the building and the bottom of the door cannot be balanced or the door gap is excessive. If this is necessary, the pivot support itself cannot implement door gap adjustment.

Therefore, the future task for this part will be to provide an alternative in the direction of fine-tuning the gap between the door and the floor.

On the other hand, among the door jambs for the door frame, there is also a door jamb 14 made of an aluminum extruded material on the surface, as shown in FIG.

Depending on the individual's preference, a commercialized adhesive design paper (not shown) may be attached to the surface of the door jamb 14 to enhance visual beauty and create a different atmosphere.

Although there may be slight differences depending on the thickness of the design paper, the shape of the design paper is not correct in the angled part of the door groove, which is angled as above, because the design paper does not adhere completely and tends to be lifted.

It is also necessary to prepare a plan that can be applied to the surface and easily attached to the decorative paper to improve the aesthetics of the doorpost.

Registered Utility Model No. 20-0246029 Publication Patent No. 10-2009-0038198 Registered Patent No. 10-1458549 Publication Patent No. 10-2018-0091592

The purpose of the present invention is to provide a self-closing door hinge that can prevent damage to the rotating hinge member by mitigating the impact when the door is closed, a pivot support that can adjust the bottom gap of the door, and a design paper can be easily and correctly attached. It is to provide an auto-closing door system consisting of a door jamb.

The object of the present invention described above is a long bolt-type hinge shaft with a head as a shaft hole drilled in the center of the plane of the upper pivot that supports the upper end of the door by inserting it into the fixing hole formed in the fixing holder installed on the bottom of the upper limb of the door frame A bracket and a single tube-type fixed hinge member with an inclined bottom, a single-tube rotational hinge member with an inclined top, a washer, and a spring for compression of the rotating hinge member are inserted one after another in the hinge shaft part that is fitted down and passed through the upper pivot. , Based on the self-closing door hinge in which a washer is inserted into the shaft end of the hinge shaft exposed to the lower end of the spring and a nut is fastened, the elasticity of the spring is partially on the hinge shaft between the rotating hinge member and the fixed hinge member. A self-closing door hinge in which a buffer spring for encroaching rotation hinge member is additionally loaded; A pivot support adapted to allow height adjustment of the pivot plate by inserting a pivot plate with a pivot hole perforated into a pivot plate hole of a substrate attached to the entrance floor or threshold, and pressing the side with a horizontal bolt to fix the pivot plate; This can be achieved through an auto-closing door system consisting of a door jamb that allows the design paper to be properly attached by forming vertical protrusions on both sides of the door groove on the surface as the boundary.

The pivot plate inserted into the pivot plate hole of the board is loosened by loosening the horizontal bolts, and then the bottom of the door is narrowed by adjusting the height, or the height of the door is adjusted and the loosened horizontal bolts are tightened again to fix the pivot plate.

형 돌조를 나란히 돌출시키는 것으로 저절로 형성되며, 형 돌출부는 직각으로 각진 종래의 도어홈과는 달리 직각으로 각진 부분이 없으므로 들뜨지 않게 의장지를 부착할 수 있다.

형 돌조는 꼭지점이 둔각일수록 의장지 부착에 유리하다.The door groove does not concavely press or cut the surface of the door jamb.

It is formed by itself by protruding the molded protrusions side by side, and the molded protrusion does not have an angled portion at a right angle, unlike the conventional door groove angled at a right angle, so that the design paper can be attached without being lifted.

The more obtuse the vertex is, the more advantageous it is to attach the design paper.

As described above, according to the present invention, the pivot support unit coupled to enable height adjustment on the fixed plate can narrow the bottom gap of the door or uniformly and easily adjust the bottom gap.

Next, with reference to the drawings below Figure 3 created on the basis of a preferred embodiment of the present invention will be described in detail in the order of automatic closing type door hinge, pivot support, and door jamb.

3 and 4 are an exemplary front view and a separated state of the door hinge 1a mounted on the top of the door according to the present invention, and FIG. 8 is a view showing a fixed holder installed on the door frame. It is a perspective view. As shown in the drawing, a fixed holder 20 of a certain thickness is fixedly installed as a piece on the bottom of the upper limb of the door frame (A), and the upper pivot 10 is inserted into the fixing hole 12 formed in the fixing holder 21 The top of the door is supported.

In the shaft hole drilled longitudinally in the center of the plane of the upper pivot 10, a long bolt-type hinge shaft 5 with a head was fitted downward, and the portion of the hinge shaft 5 penetrating the upper pivot 10 In the bracket (3), a single tube-type fixed hinge member (2) with an inclined bottom (2a) and a single-tubular rotary hinge member (4) with an inclined top (4a) are engaged with the inclined surfaces (2a) (4a). Is fitted.

"형태 즉, 물결 모양으로 형성되어 상기 회전 힌지부재(4)의 회전시 부드럽게 작동하여 소음 발생을 최소화하고, 상기 빗면(2a)(4a)의 마모를 최소화하여 유지보수에 따른 비용을 크게 절감할 수 있다.At this time, the inclined surface of the fixed hinge member 2 and the rotating hinge member 4 is "

"It is formed in a shape, that is, a wave shape, and it operates smoothly when the rotating hinge member 4 rotates to minimize noise generation, and minimizes abrasion of the inclined surfaces 2a and 4a to greatly reduce maintenance costs. I can.

Subsequently, a washer 6 and a spring 7 were sequentially fitted under the fixed hinge member 4, and one or one of the shaft ends of the hinge shaft 5 exposed to the lower end of the spring 7 A plurality of washers (8) and one or a plurality of nuts (9) are fastened and fixed as described above.

On the other hand, in the present invention, a buffer spring 22 is additionally loaded in a portion of the hinge shaft 5 between the fixed hinge member 2 and the rotation hinge member 4. The cushioning spring 30 mitigates the impact of the rotating hinge member 4 which will pressurly contact the fixed hinge member 2 by eroding a part of its elasticity against the spring 7 when the door is closed.

The buffer spring 22 is shorter than the spring 7 and has a smaller radius. Therefore, it does not significantly erode the elasticity of the spring 7, but when the door is closed by encroaching a part of the elasticity, the top (vertex) of the rotating hinge member 4 touches the valley of the fixed hinge member 2 It is enough to soften the impact so that it sits smoothly.

In addition, the cushioning spring 22 is trapped between the inner upper surface of the fixed hinge member 2 and the inner floor of the rotating hinge member 4 so that when the door is opened, the vertex of the inclined surface 4a of the rotating hinge member 4 is fixed. The spring 7 is compressed until it rises to the bottom dead center of the inclined surface 2a of the hinge member 2 and is elastically expanded by the amount corresponding to the compression amount.

When the vertex of the rotating hinge member 4 slides out of the bottom dead center on the bevel surface 4a side of the fixed hinge member 2, in other words, the spring 7 retracts in the process of closing the door. It expands and contracts due to the overwhelming force of the buffer spring 22 between the top dead center of the top dead center of the inclined surface 2a on the fixed hinge member 2 side and the inclined surface 4a on the rotating hinge member 4 side. Alleviate the violent shock that occurs.

According to the action of the buffer spring 22, damage to the rotating hinge member 4 due to the impact when the door is closed is remarkably reduced.

5 is an exploded view of the pivot support 30, and FIG. 6 is an assembly view of the same. In these figures, the pivot plate 33 having the pivot hole 34 perforated is inserted into the pivot plate hole 32 of the substrate 31 that is fastened as a piece at the lower end of the door jamb 14, and the pivot plate 33 is inserted into the side surface of the substrate 31. The pivot plate 33 is fixed by fastening the horizontal bolt 36 to the perforated horizontal bolt hole 35. The pivot hole 34 has a bearing that helps smooth rotation of the pivot 12.

When the horizontal bolt 36 is loosened, the pivot plate 33 becomes loose. This is the first action to be taken when adjusting the height or left and right movement of the pivot plate 33 on the substrate 31. If the height of the door is finely adjusted, or when the gap between the threshold or the bottom of the doorway and the bottom of the door is wide and the opposite side is narrow, loosen the side bolts (36) and then remove the pivot plate (33). Adjust the height and lock and fix the side bolts (36).

In addition, if the pivot plate 33 is moved to the left and right within the pivot plate hole 32 for fine adjustment, the horizontal bolt 36 is fixed, and the pivot 12 can be built in the center of the bearing. It becomes. That is, the position of the pivot plate 33 can be adjusted to the left and right so that the center of the bearing can be located at the position where the pivot 12 protrudes, thereby facilitating installation work.

It is a feature of the present invention that cannot be realized with a conventional pivot hole position variable pivot support.
