JP6630192B2 - High load hinge device and frame structure equipped with it - Google Patents

Description

The present invention provides a hinge device for a metal fitting door with a high load, which enables a door, which tends to be heavy due to required performance specifications, to be installed on a building without exposing the hinge member. It relates to the frame structure.

For example, in public facilities and hotels with an unspecified number of visitors, apartments and tenant offices, various measures are required by law to prevent fires from spreading in the event of a fire and to minimize damage due to smoke. Of these, the doors at the entrance and exit are not exceptional, and the required fire protection performance is required.This door has a fire resistance regulation, so it has a double-sided flash structure, and the weight of the door is heavy, so the hinge device to support the opening and closing of the door Also, a structure having a sufficient load bearing capacity is required. (Specific fire prevention equipment)
The same applies to a door door bag-shaped frame door and a waist flush door. (Fire protection equipment)

In addition, all doors have fire safety regulations and standards of the Building Law.Conventional doors always have support parts because they are necessary for opening and closing, but all of them have protruding support parts, so light weight and weight can be distinguished. For this reason, the door support is designed to be inconspicuous, and hinges are used for the exterior, and hinges are used at the top and bottom for the use of the internal door so as not to be in the line of sight of the eyes. It also has a similar color finish.
Under such circumstances, there is a demand for a smart hinge fitting that has no protruding portions and no exposed support portions applied to all doors.

In general, conventional support brackets are called take-out hangings, and hinges and pihot hinges are used, which impairs the beauty of the surroundings of the door. Incidentally, it cannot be denied that the structure is dangerous, and that the occurrence of finger stuffing cannot be denied.
For this reason, it has already been proposed as Patent No. 3876274 “door support structure”, but in reality, it is required to have strength, durability, ease of installation at the time of construction, and reduction of manufacturing cost. There is room for further improvement, such as developing under a simple form.

In addition, the one with a gentle supporting part seen in the inspection door etc. has a shaft rod of 6 mm φ for light weight and the back side of the door is hollow because it is single-sided flush, so it is easy to work, In the prior art, there was no support fitting for a double-sided flush door because the door structure was different.

In addition, the door of the automobile is structurally a one-sided flash structure, and the hinge device has a large flap to enable opening and closing. Door's door is one sided.
These examples show how important it is to keep the aesthetics smart. In addition, the door frame of the building structure has a staircase-like door (smoke return) installed within the expected frame. Contact and the door does not open.
For the above reasons, only the hinge can be installed and opened and closed on the outside.

Japanese Patent No. 3876274

The present invention has been made in view of such a background, and ensures sufficient strength so that it can be applied to a metal fitting door requiring a large load resistance, and prevents the hinge member from being exposed when the door is closed. It is an object of the present invention to propose a high-load hinge device and a frame structure provided with the same, which have realized a simple configuration and can respond to realistic demands such as ease of execution work. .

2. The hinge device for high load according to claim 1, wherein the fixed hinge mounted on the frame rotates around a base axis, and a plate connected to the door rotates the fixed hinge on the frame side. The fixed hinge is a tubular shape with a shaft rod wound around it, while the hinge plate on the door side has a cylindrical plate plate inserted into the shaft bar and has an inverted cross-sectional shape in plan view and has an outer surface of a frame. Is turned around.

In the hinge device for high load according to claim 2, the door-side plate has a cut-out relief portion on the frame to keep the opening angle of the door to the maximum, and the rotation of the door-side plate protrudes from the frame. It is characterized in that it is bent and formed into a bulged blister shape to facilitate the rotation of the door and to form a superior storage frame for the hinge device, thereby enhancing the fitting performance.

The high-load hinge device according to the third aspect of the present invention accommodates the high-load hinge device according to the first and second aspects in a door storage frame inside the frame when the door is closed. The plate plate is formed by V-groove cutting and bending, and is characterized by forming to enhance the manufacturing accuracy and to weld the bent portion to reinforce the strength.

In the hinge for high load according to the fourth aspect, the hinge for high load according to the first, second, and third aspects is such that a fixing plate is directly attached to the door first and the door is fixed to the door plate from the frame side when the door is suspended during the operation. The hinge device is characterized in that the hinge member is not exposed from inside and outside when the door is closed when the door is closed.

The high-load hinge device according to the fifth aspect is characterized in that the high-load hinge according to the first, second, third, and fourth aspects is based on the rotation of the frame and the door, and has an inverted depth depending on the thickness of the door.

High load hinge device

施行時による建物引渡の際に扉を吊込む作業性を容易に行うことができる。The invention according to claim 1 is such that the door-side hinge plate is rotated around a stereotactic shaft pin installed on the frame side, and the hinge device is housed within the door opening of the frame and is not exposed when the door is closed. U-shaped on the back of the door that is conventionally used

The workability of hanging the door when the building is delivered at the time of enforcement can be easily performed.

The above-mentioned conventional fittings are the one-sided large inspection door specification fittings that are compatible with double-sided flush doors as required. There are no conventional fittings, the material is iron, and the shaft bar is 6 mm φ and the strength to withstand the door's own weight Presented as a special method without possession. Naturally, a problem occurs in the frequency of use.

The object of claim 2 is to open the door to the maximum extent, so that a relief portion of the frame is required, and the hinge device can be appropriately installed without being exposed from the outer surface.
In addition, the bulged blister shape and the bent shape protruding on the outer surface of the frame are for improving the fitting state of the hinge device, and if the hinge device is located on the outer surface of the frame, the gap between the frame and the door is reduced. This is the most important thing for a fitting, and it has an aesthetic appearance, so 1 mm is a problem. With such a devised molding of the frame, the rotation of the door becomes a smooth specification.
In the case of steel, bending is performed by a bender machine, and since an aluminum material is an extruded material, there is no problem in terms of labor.

The invention of claim 3 supplements the manufacturing accuracy and strength of the hinge device, but the parallel dimension between the frame-side positioning shaft pin and the door determines the gap (dust) between the frame and the door on the suspension side, and furthermore, the key-side. Since it determines the gap (Chile), it plays an important role, and at the same time, the calculated position of the frame-side positioning shaft pin and its depth dimension is also important. It needs to be raised.

Further, the invention of claim 4 relates to binding of the door side fixing plate at the time of enforcement, and the device is installed at a portion within the door prospect of the frame so that the member is attached to the side of the expected thickness of the door because the member is not exposed, so the 90 degree door is attached. Although it is ideal to open and fix the screws, a hinge device without exposure can be obtained by connecting and fixing the fixing bracket L portion to the door side hinge plate extending from the frame side ahead of the door.

The hinge for high load according to claim 5 is housed in a frame in which the door is accommodated and pivots for opening and closing, and a plate bent in an inverted letter shape in plan view, which is a feature of the present invention, bypasses the frame. Since the method is adopted, it can be applied to all metal fittings and when the door thickness is different, adjust the parallel space of the door hinge plate, and adjust the gap between the frame and the door (Chile) between the fixed axis and the door. By doing so, it is possible to make preparations in production, and it is possible to obtain the effect of retaining the rotatable hood.

The embodiment of the present invention is a preferred embodiment of the embodiment described below, and further includes various forms that can be modified based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments. FIG. 1 shows a usage mode of the present invention, and shows a state in which a door D to which a hinge device 1 of the present invention is applied is supported by a frame L attached to a frame C.
First, the outline of the installation of the door D will be described as an example of the door. The frame L supporting the door D is formed in a stair-like shape to block smoke in a fire in order to return the gap between the door and the frame for legal purposes. It is installed in a state where the periphery of the door fits in between the prospects.

Hereinafter, the hinge 1 will be described. The hinge device 1 has a thrust washer 6 interposed between the frame-side hinge plate 2 and the positioning shaft pin 3, and the door-side hinge plate 4 is dropped into the hinge device 1 so that the hinge between the door plate 4 and the frame-side hinge plate 2 is eliminated so that the hinge device 1 can be freely rotated. It is set as a set.

Although the hinge device 1 is configured in this manner, when the door is closed, the gap between the door butt D and the frame L is slightly exposed by looking into the gap, but the hinge device 1 is substantially invisible from the outside. And the frame is cut out appropriately when the door is turned.

Naturally, since the hinge device is installed within the prospect of the frame, the maximum opening and closing range of the door is limited, and is limited by the jumping first bending angle of the inverted circular ring portion, and the angle is limited. If the angle becomes obtuse, the door can be opened and closed much larger, but the opening angle is appropriately limited because there is damage to the frame and the door lock, etc. Therefore, it is necessary to provide a device for preventing the hinge device from being exposed when the frame of this portion is closed.

外部仕様だと、雨仕舞、水の浸とうがあるか、ヒンジ装置を保護するトロカバーがヒンジ部の枠後部に取付られておりその心配はいらない。
また、外部仕様は一般的にセミエアータイト及び完全エアータイトで構成されていて被膜されたスポンジが枠内４周に埋込まれ、扉と接触しているので空気の樌流はなくバキュム効果は発生しなく雨仕舞は考えにくい。
しかし、従来のヒンジ金具にあるように水分による腐食は建築構造物の風当り等で条件によって差異はあるがさけられない。従来の建具と同条件である。Next is a detailed explanation of the frame relief

With the external specification, there is no need to worry about whether there is rain or water immersion, or the tro cover that protects the hinge device is attached to the rear of the hinge frame.
In addition, the external specification is generally composed of semi-air tight and completely air tight, and the coated sponge is embedded in the frame 4 times and it comes in contact with the door, so there is no air flow and the vacuum effect is It is hard to imagine a rain storm that does not occur.
However, as is the case with conventional hinge fittings, corrosion due to moisture is not avoided, although there are differences depending on conditions such as the wind hit of the building structure. It is the same condition as the conventional fittings.

Next, the frame-side hinge plate 2 rotates the door-side hinge plate 4, and the door-side hinge plate 4 and the door-side fixing plate 5 are doublely overlapped. This has the effect of reinforcing the decibel load acting in the direction of the door end and maintaining the functionality of the fitting. The door weight in the case of the steel plate in the ^W 800 × ^H 2000 52. It is estimated to be around ⁶ kg.

Next, FIG. 2 shows the rotation of the door in a plan view. The frame L stores the hinge device 1 in a prospective portion where the door will fit, and the production of the hinge device within this prospect will be described. The door side hinge plate 4 has a peculiar shape, the member is a stainless steel plate having a thickness of 3 mm, and compactness is required. Therefore, it is necessary to pursue the dimensional accuracy by appropriately V-cutting the steel sheet, and forming a cut groove for 3 minutes, 5 minutes, and 7 minutes, and performing a bending process. At this time, the plate strength is reduced, but it becomes necessary to perform beat welding.

In addition, referring to another example, the variation of the left and right up and down dust (gap) due to the dead weight of the door does not cause the sagging of the door due to the deformation of the shaft pin 3, but the seam of the cylindrical ring portion is changed. Since the mouth is open, the present invention needs to be beat-welded at the site to eliminate the problem.
The shaft pin 3 of the present invention has a diameter of 12 mm. However, for a door having a small door thickness, a shaft rod of 10 mm can be used, and can be freely replaced depending on the material of the door. The significance depends on the shape of the inverted plate.

Hereinafter, each member will be described in detail. The frame side hinge plate 2 is formed by cutting a steel plate by shearing and curling. 3 mm thick stainless steel is used to secure sufficient strength, and a plurality of screw holes for mounting on the frame side are formed. The door-side hinge plate 4 extending in the shape of an inverted letter while being parallel to the door side is based on the calculation number for opening the opening angle of the door to the maximum, and the plate 5 fixed to the door side is installed earlier. This is a part that is combined with the frame hinge plate 2 and that takes into account the ease of operation.

現場施工時の作業手間が発生し、各職人手間は違う工程であり現実的にはさけたい方法である。Here, the method of hanging the door at the time of enforcement is as follows. First, the frame and the metal fitting of the door are paired, the frame side hinge plate 2 is attached first, and then the hinge plate 4 is attached to the door side. There is a method of mounting and dropping into the protruding stereoscopic shaft pin in the frame, in which case the shaft pin has a 45 mm protrusion, so the rectangular cutout of the frame side escape portion

The labor involved in on-site construction occurs, and each craftsman's labor is a different process, which is a method that we want to avoid practically.

As another method, a method was selected in which the frame-side hinge plate 4 and the door-side hinge plate 5 were mounted and fixed, and the doors 4 and 5 were paired and connected with the door opened 90 degrees.
In addition, screw hole accuracy requires a pairing inspection in advance in the manufacturing process to produce a product and further contrivance is required, and a better change is included.

In addition, as the above-mentioned alignment that occurs when the door is suspended, the door hinge plate 4 is provided at the center of the plate. Create a ⁵ mm of Ana, 4 on the door side fixing plate 5. ³ φ × 1. ^Two screws are buried in the center and two screws are located at the center shown in FIG.

In addition, the door-side fixing plate 5 of the present invention is 3 mm, but since it is required to select a stainless steel material of 4 mm and 5 mm thick for attaching and detaching screws, there is an element for changing the thickness of the steel plate. May be changed from 5 mm to 6 mm.
In this case, it is preferable to use a molded member such as an angle instead of bending the L-shaped member, thereby obtaining the strength of the member itself.

Further, the door-side fixing plate 5 is combined with the door-side hinge plate 4 to form a pair. However, it is ideal that the screw base member is thicker from the viewpoint of durability, and it is possible to change the order of superposition of this portion. This is for obtaining the effect of the screw thread characteristic.
In addition, the angle bent in the inverted shape is 90 degrees due to this, but this angle does not deviate from the idea of the present invention and may be slightly displaced.

Next, FIG. 9 shows another modification, in which the door-side hinge plate 4 and the frame-side hinge plate 5 are joined to form a pair as described above. This is a method in which a plate plate parallel to the side is directly inserted into the dug portion of the door and fixed with screws, which is simple. FIG. 10 is a perspective view thereof.

FIG. 8 shows a modified form using another frame, and FIG. 8 (G) shows a form of a frame for accommodating a hinge device section, which shows an example of use of a hinge section using a conventional frame of the present invention. ) (J) is a form frame in which the storage of the hinge part is stored on the outer surface side. (G) and (H) and (J) are frames and doors because the dust (gap) of the marked part can be inevitably different. Good clearance, and an important number of fittings can be obtained.
In addition, the gap (Chile) is 4 mm for the hanging base, 4 mm for the key side, 3 mm for the upper side, and 6 mm for the lower side.
In order to hold such knowledge, a diagonal measurement inspection is performed in a factory inspection, and a diagonal error is 4 mm. That is, the manufacturing error is 2 mm.
As described above, the (H) protruding frame and (J) bulging frame may be in such a state that such a storage portion is formed for storing the hinge portion and finely adjusting the gap between the frame and the door with respect to the functionality of the fitting. Good. In this case, the frame has a symmetrical shape.

Further, the projecting frame shown in FIG. 8H is bent by a bender, so that the workability is simple, and the bulging frame shown in FIG. As far as it can be ingenious. Also, the heading of the frame (dimensions of the frame from the front) is 25 mm in the case of steel, but in the case of aluminum there are 30 ^M / _M depending on the manufacturer. Also applies to metal fittings.

FIG. 11 shows the conventional hinge (V), which shows the pivoting orbit of the tail of the door. When the door is opened, it moves around the frame largely, causing danger such as finger jamming. There is a danger that the worn part may get caught in clothes. Also, (W) is a digging hinge, which is the same as the above, and is a fitting which emphasizes functionality. The present invention has a pivotal movement of the door end along the frame, which is safe for finger jam and clothing, and can be compared in the plan view of FIG.
In addition, this rotation does not come into contact with the frame and does not affect the finish of the frame.

The embodiments of the present invention have been described above. However, it is needless to say that the present invention can be carried out in various forms without departing from the gist of the present invention. including.
