Problems solved by technology

However, for larger and heavier casement windows, there are still some problems below that will cause the sash glass to be damaged and fall off or even the risk of the sash falling: 1. Under the situation that the sliding stay hinge bears a larger and heavier sash, When the external force is accidentally impacted (especially when the sliding support is used for a long time and the sliding block is worn), the sliding block will be deformed or broken due to insufficient bearing capacity, and it will be detached from the slide rail, causing the window sash to fall
2. As the size ...

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Refer to 1, figure 2 , image 3 As shown, a sliding stay hinge with a five-link structure of the present invention includes a guide top angle 1, a slide rail 2, a first slider 3, a first support arm 4, a second support arm 5, a third support arm 6, a top Support cantilever 7, the fourth support cantilever 8, the second slide block 9, adjusting screws 13,15, friction pads 14,16, nylon pads, nylon sleeve pads 10,11, supporting pads 12 and other accessories. The slide rail 2 has an edge 21 folded inward, and near one end there is a flange 22 (formed by stamping process) higher than the edge 21 of the slide rail, and the flange 22 has a rivet hole 23 .

[0025] The sliding stay hinge is assembled as follows: the slider 9 is hinged with the fourth support arm...

Abstract

The invention discloses an anti-abrasion sliding support hinge which has a five-connecting-rod structure and is suitable for middle-size and large-size safety type casement windows. The sliding support hinge comprises a sliding rail, a first sliding block, a first supporting cantilever, a second supporting cantilever, a third supporting cantilever, a fourth supporting cantilever and a top supporting cantilever, and is characterized in that the first sliding block is a lengthened sliding block; the fourth supporting cantilever is hinged with a second sliding block; the second sliding block is provided with a friction pad and is inserted below the edge of the sliding rail. By the sliding support hinge with the five-connecting-rod structure, the contact stress surface between the edge of the sliding block and the edge of the sliding rail is greatly increased, so that the bearing capacity and the abrasion resistance of the sliding block are improved; and the sliding block cannot slide off the sliding rail because of outer force or abrasion.

Description

technical field [0001] The invention relates to a sliding stay hinge for a safety casement window, in particular to a wear-resistant sliding stay hinge suitable for medium and large safety casement windows. Background technique [0002] The sliding stay hinge commonly used in casement windows is a "four-link" motion mechanism assembled from slide rails, sliders, and several mutually hinged support cantilevers. One end of the slide rail is equipped with a guide corner for the opening and closing of the hinge; and there are screw holes for installation at the corresponding positions of the cantilever and the slide rail on the top support. Screws are installed and fixed on the corresponding positions of the upper and lower ends of the window frame respectively, while the top support cantilever of the sliding stay hinge is respectively installed and fixed on the corresponding positions of the upper and lower ends of the window sash. When the window sash is pushed, the window sa...
