Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nine-knuckle hinge, and more particularly to a nine-knuckle spring hinge and a non-spring hinge that can give the appearance of a three-knuckle or more than three-knuckle hinge. It is.

Doors are often mounted using concealed bearing hinges.

A typical concealed bearing system is the Parsons (Pa.
There are two vanes, one mounted on the door and one mounted on the jamb, as shown in U.S. Pat.

Between the two hinge vanes of a typical concealed bearing hinge, there are generally three knuckle bodies, the upper and lower knuckles of which are connected to one of the hinge vanes, and the central The knuckle is connected to one other hinge blade.

Generally, one of the hinge blades is attached to the door with a screw,
The other hinge vane is typically screwed to the door jamb.

In recent years, some building codes have required new construction, such as apartment homes, to have a door lock installed on the entrance door of each housing unit.

Concealed hydraulic door closures are used in high-income unit housing, but the requirements of these building codes can be met with cheaper spring hinges.

To date, spring hinges have been developed that meet the requirements of such building codes.

A spring hinge is a hinge that has a torsion spring within the cylindrical portion of the hinge that forces the door into the closed position.

The spring hinges that have been made so far have large knuckle diameters and are very long.1. They were often longer than the hinge vane and housed a spring strong enough to provide the torque needed to close the door.

Such hinges are bulky and unattractive in appearance, unlike concealed bearing hinges or other aesthetically pleasing hinges.

Thus, although the use of bulky spring hinges in conjunction with concealed bearing hinges has been permitted under building codes, such installations are generally not welcomed for aesthetic reasons. There wasn't.

In particular, the reluctance to use conventional spring hinges in conjunction with concealed bearing hinges is primarily due to the fact that such conventional hinges, as discussed above, look significantly different from those of conventional concealed bearing hinges. It was because of what he was doing.

Therefore, if a concealed bearing hinge is deemed desirable for aesthetic reasons, a concealed hydraulic door closing system must be utilized.

On the other hand, if spring hinges are desirable for economic reasons, the cosmetic differences between spring hinges and concealed bearing hinges will probably result in all hinges being aesthetically unattractive and bulky. It would be required to swing with a spring hinge.

Traditional nine-knuckle hinges have a pair of knuckles of equal length.

To convert such a conventional nine-knuckle hinge into a spring hinge, the maximum length of the spring is equal to the length of the knuckle or half the length of the entire torso.

This limitation of spring length protects the use of springs that provide torque appropriate to the requirements and prolong the life of the spring.

It is therefore imperative that spring hinges utilize springs that are sufficiently long to provide adequate torque without compromising spring operation or reliability.

In accordance with the present invention, there is provided a nine-knuckle hinge, typically comprising a pair of adjacent hinge vanes and axially aligned long and short hinge knuckles respectively formed on adjacent turns of the hinge vanes, preferably concealed bearings. Type of three knuckles
A new and improved nine-knuckle hinge is provided that can be disguised as a hinge or a hinge with more than one knuckle.

The hinge of the present invention includes an anti-friction bushing located within the end of the long hinge knuckle adjacent the end of the short hinge knuckle to act as an anti-friction bearing.

A torsion spring mechanism may be located within the long hinge knuckle to bring the hinge vanes together.

The bottle is held and supported by a short hinge knuckle.

The bindle about which the long hinge knuckle pivots extends through a bushing in the long hinge knuckle and includes a torsion spring mechanism, if there is a torsion spring mechanism in the long hinge knuckle. is fixed at one end.

A groove-like marking to give the appearance of a groove between the knuckles is provided around the outside of the long hinge knuckle at a distance equal to the length of the short hinge knuckle or at the end of the long hinge knuckle. Therefore, the nine-knuckle hinge is visually disguised as a three-knuckle hinge to serve the aesthetic purpose described above.

The more markings it has, the more it looks like a hinge with many knuckles.

Long hinge opposite the end where the bushing fits.

The end of the knuckle is also provided with a plug or capstan.

If there is a torsion spring mechanism in the long hinge knuckle, a capstan is used to fix the other end of the torsion spring mechanism in the long hinge knuckle so that it does not rotate to adjust the torsion spring mechanism. ing.

At least the long hinge knuckle of the spring hinge also has an internal shoulder defining a hole with a diameter smaller than the outside diameter of the torsion spring to prevent accidental disassembly of the hinge.

An anti-friction bushing, preferably made of plastic material, is disposed coaxially around the bottle and includes an external flange located between the long and short hinge knuckles, and includes a thrust bearing surface for the hinge and a side surface. The bearing surface is resting.

Bintle is a type of hinge adjacent to the long hinge knuckle.
It includes an external flange located within the end of the knuckle with an anti-friction surface provided by the flange of the bushing.

This flange also prevents the bottle from moving away from one of the knuckles, providing an additional level of safety.

The spring hinge of this invention can be used in the same door as the non-spring hinge embodiment of this invention or a conventional three-knuckle hinge.

If the spring hinge is used in conjunction with a non-spring hinge, it may include a plurality of hinged devices, at least one of which is a spring hinge and at least two other non-spring hinges. provided.

Each of the hinges has a pair of adjacent hinge vanes, an axially aligned long and short hinge knuckle formed on adjacent edges of the hinge vanes, and an end portion of the long hinge knuckle adjacent to the like hinge knuckle. anti-friction bushing.

A flanged pintle around which a long hinge knuckle pivots is supported within the similar hinge knuckle,
Extending through a bushing in the long hinge knuckle, the bushing has a thrust bearing surface and a side bearing surface for the hinge.

There are one or more indicia running around the exterior of the long hinge knuckle, making the hinge appear to be a three-knuckle hinge or a hinge with more knuckles.

The spring hinge further includes a torsion spring in the long hinge knuckle for joining the hinge vanes and for securing one end of the torsion spring against rotation within the long hinge knuckle and away from the similar hinge knuckle. and a device for securing the bottle to the other end of the torsion spring.

The door is thus supported by a plurality of hinges having the appearance of identical three-knuckle hinges or hinges with more knuckles, and is resiliently held in the closed position. It will be done.

When the spring hinge is used in conjunction with a three-knuckle concealed bearing hinge, an arrangement is provided for hinged support of the door to the jamb by a plurality of hinges having the appearance of a three-knuckle concealed bearing hinge. The door is forced into a resiliently closed position.

Another embodiment of the invention includes a first hinge vane having a long hinge knuckle formed on one edge thereof; a second hinge vane adjacent to the first hinge vane having a similar hinge knuckle axially aligned with the knuckle; and a long hinge vane formed on an opposite edge of the second hinge vane; a double-acting nine-knuckle spring hinge including a third hinge vane adjacent to the second hinge vane having a like hinge knuckle formed in a turn adjacent to the second hinge vane and axially aligned with the long hinge knuckle of the second hinge vane; It is.

A first bushing is provided at the end of the long hinge knuckle of the first hinge vane adjacent to the similar hinge knuckle of the second hinge vane.

Also. A second bushing is provided at the end of the long hinge knuckle of the second hinge vane adjacent to the similar hinge knuckle of the third hinge vane.

A first torsion spring mechanism is positioned within the long hinge knuckle of the first hinge vane to bring the first and second hinge vanes together.

One end of the first torsion spring mechanism remote from the second hinge vane's second hinge knuckle is rotationally fixed within the long hinge knuckle of the first hinge vane.

Similarly, a second torsion spring mechanism is provided within the long hinge knuckle of the second hinge vane to bring the second and third hinge vanes together.

A first hinge, about which the long hinge knuckle of the first hinge vane pivots, is non-rotatably supported within the second hinge vane and extends through the first bushing. , whereby the first bushing has a thrust bearing surface and a side bearing surface for the hinge.

The first bottle includes a device for securing the first bottle to the other end of the first torsion spring mechanism.

Similarly, the second hinge, around which the long hinge knuckle of the second hinge vane rotates, is supported so as not to rotate within the hinge knuckle of the third hinge vane, and is passed through the second bushing. The second
The bushing has a thrust bearing surface and side bearing surfaces for the hinge.

The second bottle includes a device for securing the second bottle to the other end of the second torsion spring mechanism.

The invention also includes a method of making a nine-knuckle, spring hinge that masquerades as a three-knuckle hinge or a hinge that includes more than one knuckle.

The method includes forming a long knuckle on one hinge vane of length equal to the knuckles of the multi-knuckle hinge.

A short knuckle is formed on the other hinge vane of equal length to the end knuckle of the multi-knuckle hinge.

One or more grooves or markings are provided around the exterior of the long hinge knuckle at a distance of a length equal to the end of the long hinge knuckle.

In this way, a long hinge knuckle can be disguised as a multi-knuckle concealed bearing hinge of multiple knuckles by adding one or more indicia to disguise the gap between the long knuckle and the short knuckle. Made.

Align the similar hinge knuckle and the long hinge knuckle,
An anti-friction bushing is inserted into the long hinge knuckle and acts as a bearing between both knuckles.

Next, when using a torsion spring mechanism, insert the torsion spring mechanism and bottle into the long hinge knuckle, secure the bottle into the short hinge knuckle so that it does not rotate, and tighten the hinge. Assemble.

Next, wrap and twist the spring mechanism to attach the spring mechanism to the long hinge.
Fixed in position within the knuckle.

A hinge made by this method has the appearance of a three-knuckle hinge or a hinge with three or more knuckles, since the one or more grooves or markings in the long knuckle give it the appearance of a multi-knuckle hinge. and can be beautifully utilized with such hinges on one door.

In order to better understand this invention, the following three parts of this invention will be explained below.
Two embodiments will be described with reference to the accompanying drawings.

Turning to FIG. 1, a spring hinge 10 according to an embodiment of the invention is shown.

This spring hinge 10 includes a first hinge vane 12
and a second hinge vane 14 between which the central body 1
There are 6.

The center torso 16 is divided into an upper hinge knuckle 18 and a camouflaged center and hinge knuckle 20, and a lower hinge knuckle 22, camouflaged by gaps 26 and grooves or indicia 24 disguising the gaps between the knuckles. There is.

As will be further explained below, the central body 16 is provided with a torsion spring 6.
A typical torsion spring is a coil spring.

Spring 60 tends to force hinge vanes 12 and 14 together.

Thus, the door supported on the hinge 10 is brought naturally into its closed position by the resilience of the spring.

The lower hinge knuckle 22 of the barrel 160 is formed at the edge of the first hinge vane 12 .

Disguised top and center hinge knuckles 18.20
is formed at the edge of the second hinge blade 14.

There is a groove 24 between the upper knuckle 18 and the center knuckle 200.
is the provision.

A groove 26 extending between the camouflaged central hinge knuckle 20 and lower hinge knuckle 220 is formed by the articulation of these knuckles 20,22.

Referring generally to FIG. 2, a conventional three-knuckle concealed bearing hinge 30 is shown.

The concealed bearing hinge 30 includes a first hinge vane 32 , a second hinge vane 34 , and a center body 36 .

The central torso 36 consists of an upper knuckle 38, a central knuckle 40, and a lower knuckle 42.

central knuckle 40 and upper and lower knuckles 38,4
The gap between 2 44.46 is three knuckles 38 respectively
, 40.

It is formed by 42 connecting parts.

The upper and lower knuckles 38, 42 are the first hinge vanes 3
It is formed on the edge of 2.

A central knuckle 40 is formed at the edge of the second hinge vane 34.

The hinge vanes 32, 34 are connected to the second hinge vane 34 between the upper and lower knuckles 38, 42 of the first hinge vane 32.
are hinged together by aligning their central knuckles 40.

A pin 48 is inserted through the upper knuckle 38, middle knuckle 40, and lower knuckle 42 that form the center side 36.

Pin 48 holds hinge 30 together and allows hinge vanes 32, 34 to pivot about central side 36.

Referring again to FIG. 1, the appearance of the spring hinge 10 of the present invention is shown to mimic that of the concealed bearing hinge 30 of FIG.

Thus, the spring hinge 10 of the present invention
It may also be gracefully utilized in doors utilizing conventional concealed bearing hinges as shown.

Referring now generally to FIG. 3, in constructing the spring hinge 10 of the present invention, the first hinge vane 12 is constructed of a durable material such as steel.

The hinge vane 12 is provided with a series of countersunk holes 50 for receiving screws.

A concealed three-knuckle bearing of the same dimensions and a similar hinge knuckle or lower hinge knuckle 22 of equal length to the end of the hinge is formed at the lowermost edge of the hinge vane 12.

In use, the hinge vane 12 with a similar hinge knuckle 22 is attached to the jamb while the other hinge vane 14 is attached to the door.

Thus, as described below, the similar hinge knuckle 22
and its pintle 58 actually supports the rest of the hinge in a normal door installation.

The second hinge vane 14 is made of the same material as the first hinge vane 12.

The second hinge vane 14 also has a series of mounting holes 50, which are countersunk to receive mounting screws.

Formed as part of the uppermost portion of the second hinge vane 14 is an elongated hinge knuckle 54 of equal length to the end and center knuckles of a concealed three-knuckle bearing hinge of the same dimensions.

To create the illusion of a three-knuckle hinge, the long hinge knuckle 54 is divided into a camouflaged upper hinge knuckle 18 and a camouflaged central hinge knuckle 20 by camouflaged markings in the gaps between the knuckles.

For example, if you want to make it look like you have five knuckles, you'll know that all you need to do is add an indicia.

In this preferred embodiment, the indicia are cut or cast into the material the same length and distance from the end of the three-knuckle bearing hinge of the same dimensions as the end knuckle of the concealed three-knuckle bearing hinge. It's Damizo 24.

Long hinge knuckle 54 has a hole 56 into which a small pin 68 is fitted.

A pin 68 projects into and secures the capstan 62, as will be discussed below.

Alternatively, the bore 56 may be provided with internal threads capable of receiving a headless set screw rather than a pin.

It is important to include anti-friction bearings to allow hinge vanes 12 and 14 to pivot freely.

To further this purpose, a portion of the long hinge knuckle 540 adjacent to the similar hinge knuckle 22 is provided with an anti-friction bushing 7.
It is designed to accept 0.

The bushing 70 is essentially a cylindrical member having at its end a radially projecting flange 71 that presses against the hinge knuckle 22.

The end of the long hinge knuckle 54 adjacent to the similar hinge knuckle 22 is sunken to accommodate the flange 71 of the bushing 70.

Further, the inner surface of the bush 70, which is disposed coaxially around the bottle 58, is in direct pressure contact with the outer surface of the bottle 58.

Thus, the bushing 70, which is preferably made of anti-friction plastic or other anti-friction material, is free-standing on both the side and thrust bearing surfaces.

To assemble the hinge, press fit the bottle 58 into the similar hinge knuckle 22 and attach the bottle flange T4.
into the sink hole in the knuckle 22.

The bottle 58 is then inserted into the long hinge knuckle 54.

Since the bottle 58 is inserted before the spring 60 is attached to it, the force required to insert the bottle 58 can be applied directly to the end of the bottle 58 using any suitable tool. .

This measure prevents the spring 60 from being subjected to the extreme forces required to secure the bottle 58 to the hinge knuckle 22.

After inserting the bottle 58, push the spring 60 into position over the bottle and capstan.

The spring 60 has several tight turns 72.7 at each end.
3, with a capstan 62 and a bottle 58
has the greatest gripping power.

By utilizing a spring wound in a direction appropriate to the direction in which the hinge 10 opens, the spring will move the cag stan 62 and the bottle 5 with increasing force as the torsion of the spring increases.
Grab 8.

A spring 60 is secured to the bottle 58 with the end of the tapered bottle 58 projecting into the long hinge knuckle 54.

A chamfer 78 at the end of the bottle 58 facilitates insertion of the bottle 58 into the spring 60, while a tapered portion 80 of the bottle 58 allows the tight turn 72 of the spring 60 to be inserted easily into the bottle 58. It's expanding.

After the spring 60 is forced onto the bottle 58, the spring 600 windings grip the bottle 58 more tightly, as will be discussed in more detail below.

The knurled portion 66 of the bottle 58 grips the interior of the short hinge knuckle 22 after the bottle 58 is pushed in, securing the bottle 58 within the similar hinge knuckle 22.

Alternatively, the bottle 58 may be secured within the hinge knuckle 22 by a pin in the same manner as the capstan 62 is secured within the long hinge knuckle, as described below.

The capstan 62 is then inserted into the long hinge knuckle 54 of the second hinge vane 14.

By raising the holes together or through the holes 56, the holes 52 in the capstan 62 that are aligned with the holes 56 in the long hinge knuckles 54 pass through the holes 56 in the long hinge knuckles 54; and receives a small pin 68 slip fit into the hole 52 in the capstan 62 to secure the capstan 62 after the spring 60 has been wound to the appropriate torque value.

Similar to the bottle 58, the capstan 62 has a spring 6.
0 to the capstan 62.

The end of the capstan 62 that projects into the long hinge knuckle 54 has a chamfer 82 to facilitate insertion of the capstan into the spring, while
The tapered portion 84 of No. 2 is the winding portion 73 where the spring 60 is packed.
is expanding.

To wind the spring 60, a drive device cooperating with the recess 63 of the capstan 62, such as a screwdriver inserted into the slot, is used to hold the first hinge vane while turning the capstan.

After winding the spring 60 to the proper torque value and raising the hole 52 as described above, a small pin 68 is inserted through the long hinge knuckle 54 and into the capstan 62 to secure it.

The torque developed by the torsion of spring 60 is applied to pin 68, thereby preventing accidental release of the spring.

Long hinge knuckle 54 has an internal shoulder 76 to prevent disassembly of hinge 10 and accidental removal of the door.

The outer diameter of spring 60 is greater than the diameter of the opening formed by shoulder 76.

As a result, the spring 60 cannot pass through the smaller diameter opening formed by the shoulder 76 and the hinge knuckles 22.54 are effectively brought together.

In addition, the bottle 58 has a flange 74 that is either milled or swaged.

The flange 74 is located in a recessed portion of the end of the hinge knuckle 22 adjacent the bushing 70.

Thus, the flange 74 not only prevents the bottle 58 from being pulled out of both knuckles, but also prevents the bushing 74 from being removed from both knuckles.
It also serves as a bearing surface for the flange 11 of 0.

The two knuckle spring hinges 10 thus formed have the appearance of the concealed three-knuckle bearing hinge of FIG.

A groove 24 in the long and narrow hinge knuckle 54 divides the section into a camouflaged upper hinge knuckle 18 and a camouflaged central hinge knuckle 20.

Long hinge knuckle 54 and similar hinge knuckle 220
Since there is a groove 24 and a gap 26 in between, the hinge 0 has the appearance of a concealed bearing hinge 30 and cannot be easily recognized as a concealed bearing hinge 30.

Thus, unlike conventional spring hinges, the spring hinge 10 of the present invention can be aesthetically utilized with concealed three knuckle bearings and hinges of the type shown in FIG. .

It should be understood that sign 24 can be made by cutting miso.

Also, for example, if the hinge is made by stamping and forming wrought metal, the grooves 24 may be cast into the flat stock prior to forming the long hinge knuckles 54, or the markings 24 may be Any other method may be used as desired.

Referring now generally to FIGS. 9-11, if a spring hinge suitable for field adjustment is desired, a plurality of circumferentially spaced holes are provided radially within the capstan.

The number of holes provided will depend on how precise torsional adjustment is required.

In this way, the provision of two diametrically opposed holes allows the capstan to rotate 1800 times both counterclockwise and clockwise to adjust the tension of the spring.

When six spaced holes 88 are used, as shown in FIGS. 9-11, the capstan 86 can be indexed 6000 degrees in either a counterclockwise direction or a clockwise direction. Precise adjustment of the spring is possible.

Also, the rectangular slot 63 of the capstan 62 of FIGS. 1 and 3 can be replaced with a hexagonal slot 90, so that the capstan 86 can be adjusted with an Allen wrench rather than a screwdriver. .

Some building codes allow lighter weight doors to be hung with one spring hinge and two conventional butt hinges.

Heavier doors may optionally use two or three spring hinges.

When spring hinges and non-spring hinges are used on the same door, they must have the same basic dimensions to maintain proper door operation and for aesthetic purposes.

For optimal mechanical compatibility, it is desirable to utilize non-spring hinges and the aesthetic counterpart of the spring hinge of FIG. 1 with such spring hinges.

Turning now to FIG. 4, there is shown a non-spring hinge 110 which is the counterpart of the spring hinge 10 of FIGS. 1 and 3 above.

This non-spring hinge 110 has a first hinge vane 1
12 and a second hinge vane 114 with a central barrel 116 therebetween.

The center torso 116 has a camouflaged upper hinge knuckle 118, a camouflaged center hinge knuckle 120, and a lower hinge knuckle 1 by means of a gap 126 and an indicia 124 disguising the gap.
It is divided into 22 parts.

The lower part of the body 116, that is, the similar hinge knuckle 122 is
A tee is formed at the edge of the first hinge blade 112.

Disguised upper and center hinge knuckles 118 and 120 are formed on the edges of second hinge vane 114.

The hinge vanes 112, 114 include a series of countersink holes 150 for receiving screws.

As with the spring hinge 10, it is important to include anti-friction bearings to allow the hinge vanes 112, 114 to pivot freely.

Accordingly, the portion of the long hinge knuckle 1540 adjacent to the similar hinge knuckle 122 is adapted to receive the anti-friction bushing 170.

Bushing 170 is essentially similar to hinge knuckle 122.
The bushing 170 is a cylindrical member having a radially projecting flange 171 at the end of the bushing 170.

The end of the long hinge knuckle 154 adjacent to the similar hinge knuckle 122 is sunken, and the bush 170
The flange 171 is housed therein.

Further, the inner surface of the bush 170 coaxially arranged around the bottle 158 is in direct pressure contact with the outer surface of the bottle 158.

Therefore, the bushing 170 serves as both a side bearing surface and a thrust bearing surface.

The plug or capstan 162 of the non-spring hinge 110 is generally of the type of capstan 62 of the spring hinge 10.

However, the capstan 162 is press fit into the long hinge knuckle 154 rather than being pinned.

Since the bindle 158 is similar to the bindle 58 of the spring hinge 10, although it need not have a knurled portion, the flange 174 is recessed at the end of the similar hinge knuckle 122 adjacent the bushing 170. It is located within the

Not only does the flange 174 prevent the bintle 158 from being pulled out of both hinge knuckles, but it also provides a bearing surface for the flange 171 of the bushing 170.

However, since there is no spring in the long hinge knuckle 154, the knuckle 118 need not be bored to receive such a spring and the non-spring hinge 11
0 can be separated.

Thus, the long hinge knuckle 15 of the hinge vane 114
4 can be raised from or lowered onto the bottle 158 which is press fit into the hinge knuckle 122 of the hinge vane 112.

Referring now to FIG. 12, a spring is positioned between a pair of non-spring hinges 110, 110.
A door 190 is shown suspended from a jamb 192 by hinges 10.

The hinge vane 14 of the spring hinge 10 is attached to the door 190
The hinge vanes 12 of the spring hinge 10 are attached to the jambs 192, while the hinge vanes 12 of the spring hinge 10 are attached to the jambs 192.

If a non-spring hinge 110, 110 is used on the same door as the spring hinge 10, a long hinge knuckle 154 may be used to connect the hinge vanes 114, 114 to the door 1.
90 , while hinge vanes 112 , 112 having similar hinge knuckles 122 are attached to jamb 192 .

In this way, optimum mechanical and aesthetic compatibility is achieved.

When assembling the hinges to the door and jamb, hinge 11
0, 110 are easily disassembled, and the hinge blades 112, 1
12 is disassembled from the hinge vanes 114, 114 and attached to the jamb 192.

Similarly, the disassembled hinge vanes 114, 114 are attached to the door 1.
Although the door 190 is attached to the jamb 90, the door 190 may be separated by the jamb 192.

After attaching the hinge vanes 112, 112 to the jamb 192 and the hinge vanes 114, 114 to the door 190, the door 190 simply attaches the long hinge knuckles 154, 154 to the hinge knuckle 122. It can be easily hung from the jamb 192 by simply positioning it above and in line with the bottles 158 and 158 (see FIG. 4).

The door 190 is then aligned with the jamb and the long hinge knuckle 154. 154 onto the bins 158, 158 (see FIG. 4).

Note the chamfer and taper at the end of the bottle that protrudes from the long hinge knuckle on the jamb to help the bottle enter the long hinge knuckle on the door. Should.

Finally, hinge vanes 14 and 12 of spring hinge 10 are simply and easily attached to door 190 and jamb 192, respectively, between non-spring hinges.

In this way, the nine-knuckle non-spring hinge ii
Utilizing the spring hinges 10, the door 190 can be easily hung from the jamb 192.

The invention also provides non-spring hinges 110, 110
It is also contemplated that a conventional concealed bearing hinge could be used instead.

Referring now to FIGS. 5-8, there is shown a double acting spring hinge 210 which allows the door 280 attached thereto to rotate 1800 clockwise or counterclockwise.

The double-acting spring hinge 210 has a first hinge blade 2
12 and a second hinge blade 213, between which the body 2
It is equipped with 16.

The torso 216 is divided into a camouflaged upper hinge knuckle 218, a camouflaged middle hinge knuckle 220 and a lower hinge knuckle 222 by a gap 226 and an indicia 224 disguising the gap. There is.

The double-acting spring hinge 210 further includes a third hinge vane 214 with a body 236 between the third hinge vane 214 and the second hinge vane 2130.

The torso 236 has a camouflaged upper hinge knuckle 238 and a camouflaged central hinge knuckle 240 with a gap 246 and indicia 244 disguising the gap.
, and a lower hinge knuckle 242.

The first hinge blade 212 and the third hinge blade 214 are
It is provided with a different countersunk hole 250 which is used to receive a screw, as shown in phantom in FIGS. 6-8.

Similar to the single-acting spring hinges of FIGS. 1 and 3, barrels 216 and 236 each receive a torsion spring (not shown) of the type used in the spring hinge of FIG. ing.

A spring in the shell 216 tends to bring the hinge vanes 212, 213 together, while a spring in the body 236 tends to bring the hinge vanes 213, 214 together.

To perform these actions, the spring has different working parts.

In this manner, the door 280 supported by the hinge 210 will automatically close whether it is opened in a clockwise or counterclockwise direction.

a long hinge knuckle 254 of the first hinge vane 212;
The long hinge knuckles 252 of the second hinge vane 213 are fitted with capstans 262 and 248, respectively, and these capstans have the same structure as the capstans of the single-acting spring hinge 10 of FIGS. 1 and 3. belongs to.

Thus, capstans 262 and 248 have slots 263 and 249, respectively, and hinges 210, respectively.
The blades inside the long hinge knuckles 254 and 252 (
(not shown) can be adjusted to twist.

Bintle (
(not shown), these bintles are of the same construction as the single acting spring hinge bintles of FIGS. 1 and 3.

It should be noted that the adjustable capstans of FIGS. 9-11 can also be used in place of capstans 262,248.

For mounting, the hinge vane 212 with a long hinge knuckle 254 is screwed to the door 280 and the hinge vane 214 with a similar hinge knuckle 242 is screwed to the jamb 270.

Thus, in normal door boxlocks, similar hinges and
The knuckle 242 and its bindle effectively support the rest of the double acting hinge.

Both the non-spring hinge of FIG. 4 and the double-acting hinges of FIGS. 5-8 can be made from the same materials and in the same manner as the single-acting spring hinges of FIGS. 1 and 3. should be understood.

The same method is also used to create the illusion of a five-knuckle hinge or a multi-knuckle hinge such as those previously described.
