Abstract

PROBLEM TO BE SOLVED: To provide wide range motion between the two axes and a hinged element. SOLUTION: A compound hinge system has a first link and a second link. The first link includes a knuckle and a bow-shaped engaging surface constituted so as to engage with a projecting part or a lug of a second link member and adjacent to a stopping part. The second link member includes a knuckle of a first set and a knuckle of a second set. While one set in the knuckles of these two sets oppositely turns to the first link by cooperating with a hinge pin, the other second set oppositely turns to a second element by receiving the hinge pin. The lug or the projecting part slides on the engaging surface, bends these outward by pushing the stopping part, and requires additional force so as to move between various stopping positions in the motional range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to hinges, and more particularly, to hinges that provide two pivot axes for two-stage movement and greater range of movement.

[0002]

BACKGROUND OF THE INVENTION Enclosures utilize multiple hinges or hinges on a cover or door to provide access to the interior of the enclosure. Hinges are often mounted (or mounted) along the sides of the enclosure to keep the door from closing under its own weight. As can be appreciated, devices that prevent the enclosure door from freely closing and swinging are beneficial for providing long-term access to the interior of the enclosure. Conventional door and hinge constructions often do not have a closure device, and the door balance and weight prevent accidental closure. However, in some cases, it may be beneficial to include a structural stop in the door that allows opening and closing, but requires more force to close,
The door can be held in an open position. This is especially important in outdoor conditions where wind can engage the flat surface of the door and tend to open or close the door. Another problem with doors and hinges is to provide sufficient mobility for the cover. In a hinge and door combination in which the door opens substantially 180 degrees, the door may be deployed away from the enclosure and, when exposed, the door may be closed by wind or the hinge may be closed. Must be able to withstand forces in the opposite direction of the blockage, which can damage or even break the hinge. Such a situation may occur in an enclosure having a cover on an open top, or having a door lying substantially horizontally and exposed in an open position. Although there are doors that open to a greater range of motion, workers often rest or rest on the door, occasionally damaging the hinges or breaking the door.

[0003] Door and hinge systems are known to provide a greater range of motion. However, such systems typically require special mounting configurations, which detract from their utility or appearance. Such systems also limit access to the interior of the enclosure. In addition, such systems do not provide any resistance to door closure, so that doors can still be accidentally rocked closed when exposed to, for example, wind power.
A further disadvantage of such a system is that the type of movement required often damages the gasket that is wiped or rubbed by the cover during some part of the open-close movement.

[0004]

As can be appreciated, there is a need for a new and improved obturator (fastener) and hinge system. Such a system should provide a free range of motion so that the door can open against the side of the fastener to minimize the effects of wind. Such a system should also provide a range of motion that resists accidental closure and does not damage or wear the gasket of the enclosure cover. The present invention addresses these and other issues associated with enclosures and hinges.

The present invention relates to hinges, and more particularly to a compound hinge that provides rotation in two axes and extensive movement between hinged elements.

[0006]

SUMMARY OF THE INVENTION A compound hinge includes a first basic hinge link attached to a first element. The first link includes a raised plurality of knuckles through which the hinge pins are received. The base has a recess formed to receive a mounting device such as a screw or bolt for binding to the first element. Between these knuckles is an arcuate surface configured to receive and align the lugs of the second link. These receptacles are adjacent to a pair of opposing stop members that bend slightly and bend when pressed by the corresponding lugs. These stops act as toggles to hold the hinge in place. These knuckles may also include stops that position the second link with respect to the first link. The second link includes two sets of knuckles for receiving hinge pins. The first knuckle is configured to align with and have an orifice coaxial with the knuckle of the first link. The second link is parallel to and aligned with the lugs that the first set of knuckles and the second set of knuckles extend substantially orthogonal to the axes of the knuckles. These lugs are first
It is configured to extend into a receiving portion of the link. The first knuckle is aligned with the knuckle of the first element and the second set of knuckles of the second link receives a pin for fastening to the second element. In this way, the second link is hinged to the first link, and the second link is also hinged to the second element. The first knuckle also includes a complementary stop which cooperates with the stop at the knuckle of the first link to limit relative rotation. These knuckles also form a toggle device in one embodiment to provide additional rotational resistance at predetermined rotational positions.

[0007] When assembled, the lugs engage the receiving surface and are held in place by stops at the base on the first link member. When the cover or door is opened and rotated relative to the second link, it reaches its full range of motion, but the door can be further opened to a first element such as a housing. At this point, continued rotation pushes the lugs against the stop elements, causing them to bend slightly until the lugs push past them. The second hinge member will then rotate freely relative to the first hinge member, reaching a further range of rotation.

[0008] To close the hinge, the second element is a second element.
Rotating with respect to the hinge member, the complementary stops engage and resist rotation. However, additional rotation occurs and the second
The element reaches its full range of motion relative to the second hinge member, and further rotation of the second element causes the lug to flex the stop element into the lug, pushing the lug back to its original position. Make it possible.

The arrangement of the present invention provides a simplified and reliable hinge, which provides a wide range of motion. In addition, the toggle effect from the lug engaging the stop element acts as a retainer,
Hold the door in either the open or closed position. However, if there is continued pressure, the door can be easily closed. The present invention allows other existing doors and enclosures to be easily assembled and retrofitted.

[0010] These novel features and other advantages which characterize the present invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, in order to better understand the present invention, its advantages, and the objects attained by its use, the drawings and preferred embodiments of the present invention, which form a further part of this specification, are illustrated by Reference should be made to the accompanying description, which is shown and simplified.

[0011]

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, and particularly to FIG. 1, a portion of an enclosure 20 having a compound hinge 22 is shown. Hinge 22 pivotally connects cover or door 26 to housing 24. As shown in FIGS. 2-4, the compound hinge 22 provides two separate axes of rotation, providing greater freedom of movement and movement between the door 26 and the housing 24.

Referring now to FIG. 9, the door 26 is shown in more detail. The door typically includes a ledge around its perimeter, forming a channel (groove) 42 for receiving a gasket 44 as shown in FIG. 10 to form the housing 24 as shown in FIG. Sealed or sealed. As shown in FIG. 9, the cover includes a recess 46 formed along one edge of the door 26 for attaching the hinge 22, and the hinge 22 and the door 2.
And an alignment bore 48 for receiving a hinge pin 28 (not shown in FIG. 9) that provides pivoting movement between the two. Along the opposite edge of the door 26 is a latch 40.

Referring now to FIGS. 11 and 12, the door receiving portion of the housing or enclosure 24 is shown. The housing 24 can be a molded unitary element, but can include a collar 30 that forms a rectangular opening that is fitted to the top edge of the housing 24 side, as shown in FIG. The collar 30 includes an inner ridge 32 that extends upwardly and engages a gasket 44 in a closed position, as shown in FIG.

The collar 30 may also include a mounting hole 38 and an alignment stud 34 that engages the base of the first link member described below. The collar 30 also defines a channel 36 which is inserted over the top of the wall edge of the housing 24.

Referring next to FIGS. 5 and 6, the first link member 50 is shown. This first link member 50
Includes a base 52 having a pair of mounting holes 58 formed therethrough. These mounting holes 5
8 is equally aligned with (two) first hinge knuckles 54 that are coaxially aligned to receive hinge pins 28. These first knuckles 54 include a stop 56 at about 90 degrees. The radially extending end surface of the stop 56 cooperates with a complementary surface on the second link member, as described below. Between these first knuckles 54 is a lug receiving recess 60 formed in the base 52. These lug receiving recesses 60 receive corresponding lugs of the second link, as described below. The stop fingers 62 are spaced from the respective lug receiving recesses 60. These stop fingers 62 act as surfaces for engaging lugs. Because of the space on each side of these fingers 62 and the fact that they are tied at only one end thereof, the fingers 62 bend and allow the second link to rotate, as described below. The lag allows the toggle operation.

Referring to FIG. 7, a second link member 70 is shown, and as shown in FIGS.
6 and the first link member 50. The second link member 70 includes a second knuckle 72, a third knuckle 74, and a lug 76. The second knuckle 72 includes a bore 88 formed therethrough and is configured to receive the hinge pin 28 for pivotal attachment to the cover 26. This second knuckle 72 includes an arcuate surface 78 to provide clearance during rotation relative to the cover 26. The end of the second knuckle 72 includes a stop 92 at about 90 degrees. The radial end faces of these stops 92 are respectively complementary to and cooperate with the ends of said stops 56. Referring again to FIG. 7, the third knuckle 74 includes an arcuate outer surface 82, which is the base 52 of the first link member 50.
Provides rotation relative to The third barrel (third knuckle) 74 also includes a bore 90 for receiving a hinge pin for coupling the first link member 50 with the first knuckle 54. A lug 76 extends downward from the lower part of the third barrel 74. These lugs 76 include cam-like surfaces 84 forming corners 86. These lugs 76 are separated from each other and are configured to be inserted into the recesses 60 on the first link member 50. The second link member 70 is aligned or aligned with the first link member 50 by the corner portions 86 of the lugs 76 engaging the corresponding stop fingers 62. The rotation here can be achieved by the lugs 76 pressing on the stop members 62 until the fingers 62 bend and allow rotation. The cam surface 84 rotates and slides against the associated stop finger 62 that is bent.

Referring again to FIG. 1, when the composite hinge 22 is in the closed position, the cover 26 blocks the housing 24 and the gasket 44 tightens and seals the ridge 32 of the collar 30. The second link 70 is in a substantially vertical position and the cam-like surface 84 of the lug 76 is
It is stationary against The corner 86 of the lug 76 is stationary against the stop finger 62 of the first link member 50.

The radially extending end of the stop 92 of the second knuckle 72 of the second link member 70 cooperates with the corresponding stop 56 of the first link member 50 from the end face side in FIG. As shown in the sectional view, further rotation in the clockwise direction is prevented.

When the cover 26 is opened, the cover 26
Rotates relative to the second link member 70, but the second ring member is still stationary from the closed position. The resistance of the finger 62 engaging the lug 76 prevents this second link member 70 from rotating with respect to the first link member 50, while the cover 26 rotates with less resistance.

The cover 26 has its maximum range of motion relative to the second link member 70, ie, about 180 degrees of movement due to the outer edge of the recess 46 of the cover 26 engaging the outside of the second link 70. Reach the maximum range of motion. Further rotation of the cover 26 with respect to the second link member 70
During normal use, this is not possible because the cover 26 tends to stay in the position shown in FIG. The application of further rotational force to the cover 26 tends to rotate the second link member 70 counterclockwise, as shown in FIG. This pressure creates a torque about hinge pin 28 that extends through the first and second knuckles and exerts pressure on finger 62. A lug 76 pushes finger 62 to flex it out of the way, and hinge 20 passes through the toggle operating point until cover 26 reaches the position shown in FIG. This is effectively 2
Provides a 70 degree range of motion. At the position shown in FIG.
The cover 26 is substantially parallel to and extends along the edge of the housing 24 so that the effect or effect of the wind catching and closing the door is negligible.

When the cover 26 is closed, the stop fingers 62 are again pushed by the lugs 76, but in the opposite direction, as shown in FIG. 4, to withstand clockwise rotation. However, the door 26 is free to rotate above the axis of rotation passing through the second knuckle 72 and returns to the position shown in FIG. The cover 26 is stationary against the side of the second link 70 and further rotation of the cover 26 relative to the second link member 70 is not possible. In addition, finger 62
Is applied with additional pressure and the fingers 62
6 withstands rotation so that the door does not close until forced to bend. When the finger 62 bends to the right as shown in FIGS. 1-4, the lug 76 can move back to the position shown in FIG. 1 and the cover 26 is closed again. However, the additional resistance required to flex the finger 62 provides a slightly increased resistance, and the cover 26 is in the open position without the additional force being applied to overcome such resistance. Will stay.

Referring to FIGS. 13-19, there is shown a second embodiment of a composite hinge, generally indicated at 120, in accordance with the principles of the present invention. This composite hinge 12
0 is the same as the hinge 20 described above, but the toggle device 180
Are added to provide greater rotational resistance to hold the hinge in place. The toggle device 180 includes a concave portion 182 formed in the first knuckle 154 of the first hinge member 150 and a second knuckle 172 of the second hinge member 170. First knuckle 1
The arcuate peripheral surface of 54 or the complementary surface of the second knuckle 172 includes a raised flange 184 that
It is configured to partially extend at a toggle position into the complementary recess 182 in the other one of the fourth or second knuckle 174.

FIG. 13 and FIG.
The first knuckle 154 and the second knuckle 172 have greater resistance to rotation when engaged as shown in FIG. When the cover 26 rotates about the second hinge member 170, the first knuckle 154 and the second knuckle 172
Has a mechanical stop to prevent the first hinge member 150 and the second hinge member 170 from rotating relative to each other. Further rotation requires slightly greater force to disengage toggle assembly 180 and allow or allow rotation between first hinge member 150 and second hinge member 170. As shown in FIG. 18, the flange portion 184
A knuckle 172 can be formed. in addition,
As shown in FIG. 19, the second knuckle 172 is
86 and the recess 182 and the recess 1
86 includes a pin member 188 extending into both of them. As with the flange 184, the pin member 188 also provides resistance and the same toggle effect. The toggle assembly 180 provides adequate resistance to allow the hinge 120 to be held in place. Toggle assembly 1
Although 80 is shown at the top of the first knuckle 154, it will be appreciated that the toggle position can be easily moved if needed at different locations along the range of rotation. In addition, the recess 182 and the ridge 184 may still achieve the desired toggle effect even if inverted.

The design of the present invention provides a simplified hinge mechanism that allows for a 270 degree range of motion. In addition, the collar 30, hinges 20 or 120 provide a retrofit enclosure that allows such a system. The system also rotates about two different axes, and the finger 62 acts as a stop to prevent the door from rocking and closing without sufficient force to cause bending of the finger. Because the cover 26 rotates about an axis away from the enclosure housing 24, the cover does not rub the gasket and a better and longer lasting seal is maintained.

It should be understood that while numerous features and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the present invention, the disclosure is illustrative only. For the purposes of the present invention, various changes may be made, particularly in terms of shape, size, and arrangement of various parts, within the full scope of the invention, as indicated by the broad implications of the claims. Can be done.
