Description

Hinge {A HINGE}

The present invention relates to a hinge, and in particular to a support block for providing an increased support surface and a support for a fastening means between two pivotally arranged parts of the chassis hinge. The present invention is particularly for use in the top hung window. Also provided is a stay open restrictor device. Such a device allows the chassis to be in the open position until the limiting means are released.

Fastening means for parts of the vent hinge are known in the art. Such means must allow the part to pivot to open and close the hinge. Fastening means including riveting, screwing and pinning are known in the art. When the vent is open, the weight of the chassis supported by the hinge forces the pivoting device of the hinge part. In conventional known designs, this force is absorbed by the fastening means of the turning device, which can lead to errors of the fastening means. This is a particular problem for most fastening means in the lower part between the support track of the hinges in the upper up and down windows and the rotatable parts. This results in frequent errors of the fastening means during inspection, and if the hinge is used to support a heavy chassis, increased wear and ultimate permanent failure of the fastening means can occur. The prior art does not suggest how to improve this situation.

It is therefore an object of the present invention to provide an improved turning device which reduces this force on the fixing means and disperses the weight of the chassis in an improved manner. More particularly, the present invention provides a hinge for supporting the chassis between a closed position in which the chassis lies in a fixed frame and an open position in which the chassis extends at an angle with respect to the fixed frame. The hinge includes a support track having a first hole; A link having a second hole; A support block having a third hole and positioned between the support track and the link; And fastening means passing through the holes in the support track, the support block and the link, the support block comprising a body portion and a collar extending from the body portion and circumscribing a hole in the support block, the collar In use extends into a hole in the link such that the link leans on the collar rather than the fastening means.

The support block is provided for use in the hinge supporting the chassis between a closed position in which the chassis rests within the fixed frame and an open position extending at an angle with respect to the frame in which the chassis is fixed. The support block can be made of any material that is substantially strong enough to withstand the forces disposed thereon, although the plastic material is also acceptable, preferably made of metal. The metal support block can be manufactured from any machining technique known to those skilled in the art, such as grinding, drilling, die casting, non-conventional machining techniques suitable for this purpose, preferably for die casting. Can be prepared by

The support block includes a body portion and a collar extending from the body portion and circumscribing a hole in the support block. The collar is preferably continuous and circular, but may also be discontinuous. The support block is located between the support track and the link, the support track preferably comprising a base and two opposite sides with inwardly facing flanges holding the body part in the support track.

The support tracks and links also include holes. Fastening means, for example rivets or screws, preferably rivets, are provided which pass through all three said holes and are fixed to the support track. The collar of the support block extends into the hole in the link. The body part is held fixed in place by the fastening means and the inward flanges of the support track, thus preventing the support block from rotating. Optionally, the body portion comprises a recess and the support track base is deformed into the recess, for example when the rivet is applied to the system. This makes the positioning of the support block, and therefore the turning point, robust.

The support track, the support block, the link and the fixing means comprise a pivoting device, the support track is fixedly mounted to the frame by a plurality of screws or the like through a keyway and a mounting hole, and the link centers the collar and the fixing means. Rotate to In this way, the force on the fixing means is reduced and the weight of the chassis bears the body portion of the collar and the support block through the link in use. As a result, the support block provides an increased support surface and support for the fixing means. When the vent is opened, the force can also be applied at right angles to the support track which is almost all supported by the fixing means in a conventional turning device. In the present invention, this force is also directed to the support track through the collar and the body portion of the support block, which is prevented by the fixing means and the inward flanges of the support block.

The improved swing device of the invention is described herein in particular with respect to the swing device between the support track and the link of the hinge. However, it is within the scope of the person skilled in the art to realize that the swing device is used between any pivotally arranged parts of the hinge to reduce the force exerted on the securing means of the swing device.

A support opening limiting device is also provided to prevent closure of the chassis into the fixed frame.

Support opening limiting devices are also known in the art. Such a device allows the chassis to remain in the open position until the limiting means are released.

The support opening limiting device of the present invention includes a support track; A slider for sliding along the support track; A restrictive link for connecting the support track to the chassis; And means for limiting the movement of the slider.

The support track of the support opening limiting device is preferably identical to the support track of the hinge described previously. However, it is within the scope of the person skilled in the art to realize that the support opening limiting device described herein also functions if the supporting track of the support opening limiting device is separated from the supporting track of the hinge. In fact, it is clear that if the two support tracks are different, the support opening limiter can be used regardless of the shape of the hinge fitted to the chassis. The support track of the support opening limiting device may be made of any suitable material, but is preferably made of metal, such as steel.

Limited links are also provided. One end of the restrictive link is pivotally attached to the slider using any suitable method, for example screws, preferably rivets, among screws, pins, rivets. The slider takes the form of a support block described herein having a body portion and a collar to extend into the restrictive link for further reinforcement. The end of the restrictive link farthest from the slider can be connected directly to the chassis. Optionally, the support opening restrictor further comprises a chassis plate, the chassis plate being pivotally connected to the restriction link. The chassis plate may be attached to the chassis by any suitable means such as, for example, screws, pins, rivets. The restrictive link and the chassis plate may be made of any suitable material, but are preferably made of a metal such as steel.

The slider of the support opening limiting device is located between the support track and the limiting link, the support track comprising two opposite sides having a base and an inward flange holding the slider. The slider and the restrictive link are pivotally connected. The slider is allowed to slide along the support track while being held on the track through the inward flanges. The slider can be made of any material, but is made of metal, for example steel, with a plastic skin to prevent wear between the slider and the track.

The limiting means are also attached or supported to the slider, preferably via any suitable means such as screws, pins, rivets. The limiting means can be made of any suitable material, but is preferably made of steel or plastic material. The limiting means limits the movement of the slider along the support track, thus allowing the chassis to open and lock in one or more different directions.
