Description

Technical Field

[0001] The invention relates to a hardware device, in particular to a simple multi-dimensionally adjustable folding door control hardware device. Background Art

[0002] Folding door is an opening and closing system composed of multiple doors, with a minimum of 2 doors and up to 8 doors or even more. Its control hardware is the key to its security performance and smooth operation. Folding door control hardware includes upper hinge single-leaf adjustment components, double-wheel upper hinge parent-child adjustment components, single-wheel upper hinge single-leaf adjustment components, middle parent-child handle hinges, lower rail parent-child hinge adjustment components, parent-child connecting hinges, lower rail single-leaf hinge adjustment components and lower hinge single-leaf adjustment components.

[0003] Since the composition of folding doors is relatively complex, the errors caused by product manufacturing and installation will cause problems such as jamming and unsmoothness when the folding doors are combined with multiple leaves. Existing domestic and foreign products also have up and down and left and right adjustment mechanisms, but due to design reasons, their adjustment methods usually have the following problems:

[0004] ① The adjustment direction is diverse, some products are adjusted horizontally, while some products are adjusted vertically;

[0005] ② For the same set of products, the adjustment tools are varied, for example, some adjustments use a flat-blade screwdriver, while others use a hexagonal wrench;

[0006] ③ The adjustment angles are different, especially some adjustment operations do not take into account the user's convenience, and there are no obvious signs, such as the signs for adjusting up and down or left and right, etc. These problems cause the installer or consumer to face problems such as tool use and operational feasibility in the actual adjustment work.

[0007] The problems of the existing folding door control hardware described above are mainly because the actual errors in the installation and use of the folding door, as well as the operational feasibility of the installer and the consumer, are not taken into consideration when designing the product. Therefore, it is necessary to improve the folding door control hardware from the perspective of mechanism design, including:

[0008] ① Consider the conversion of adjustment direction in the adjustment direction to form the consistency of adjustment direction of different products;

[0009] ② Consider the consistency of the adjustment tool when selecting the adjustment actuator;

[0047] The working principle of the present invention is:

[0048] The present invention has an ingenious structure and is easy to use. The upper hinge single-leaf adjustment component 1 and the lower hinge single-leaf adjustment component 8 use a bevel gear structure to convert the adjustment direction, thereby converting the adjustment operating surface to the outer surface of the product, making the adjustment method convenient. The adjustment mechanisms of different products in the whole set of devices are unified, so that the adjustment methods of different products in the whole system are consistent and convenient. It can bear weight and can be easily adjusted using a hexagonal wrench. The stop sleeve design that uses its own weight to lock after adjustment is simple and effective to operate. The lower guide rail parent-child hinge adjustment component 5 and the lower guide rail single-leaf hinge adjustment component 7 use a cam plus a hexagonal screw to fix them, so that the rubber-coated bearing can be easily adjusted up and down and front and back.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
