Abstract

The invention relates to a middle folding door, in particular to a shaft-free middle folding door in the field of furniture. The middle folding door consists of an upper half door, a lower half door, fixed plates, movable plates, pin shafts, and a tension spring; the fixed plate is arranged on the upper half door; the movable plates are arranged on the lower half door; each movable plate slides in a circular arc sliding chute of the fixed plate by two pin shafts on the movable plate; when the lower half door is moved by external force, the lower half door can slide in the circular arc sliding chute of the fixed plate by two pin shafts on each movable plate so as to finish opening and closing the lower half door; and any hardware cannot be seen from the front of the door because the door is not provided with a folding leaf, but the two half doors can be opened normally, simple and convenient and clean feeling is provided for people, and the grade of furniture is improved.

Description

There is not folding door in the axle

Technical field:

The present invention relates to a kind of middle folding door, particularly a kind of no axle folding door that is used for the furniture field.Be used for household and require the middle folding of Men Nengcong, and high-grade furniture very attractive in appearance.

Background technology:

No matter folding door in existing is left and right opening door or go up downward swing door, all folding must be arranged, and folding must be exposed at the middle part of door, in high-grade furniture and family expenses apparatus, like manual or electronic lifting cabinet, just attractive in appearance inadequately.Be necessary to develop a kind of can shutter door, and don't the top grade that exposes folding does not have folding door in the axle.

Summary of the invention:

The present invention is directed to the problem that prior art exists, provide a kind of and can accomplish the shutter door action, and don't expose folding door in the no axle of folding, the present invention realizes through following technical scheme:

Folding door is made up of first door, second door, stator, moving plate, bearing pin and spring in the described nothing axle; Stator is installed on first door; Moving plate is installed on second door, and moving plate is inserted in the garden arc chute of stator, when moving second with external force with two bearing pins on it; Second meeting is slided in the arc chute of the garden of first stator with two bearing pins of moving plate; Accomplish second shutter door action, the spring hook is arranged on stator, the groove or the hole that hang spring are arranged on the bearing pin of moving plate; The arc center, garden of the garden arc chute of stator is exactly first centre of gyration during with second shutter door, and second two bearing pin centers must be on the arc center line of the garden of first garden arc chute.

Folding door in the described nothing axle between stator spring carrier arm and moving plate bearing pin, has been installed extension spring.

Folding door in the described nothing axle, stator and moving plate also can be installed by transposition.

Folding door in the described nothing axle also can level or installation otherwise.

The present invention and original compared with techniques needn't carve the groove that folding is installed on door, also needn't folding be installed in the positive visual position in one's power of door; Like this in the front of door; In the vision coverage area, can't see any five parts in addition, and two film gates can open and close normally; Give a kind of simple and direct, clean sensation of people, improved the class of furniture.

Description of drawings:

Fig. 1: be that the present invention does not have folding door in the axle, the observer is positioned at the proceeds posterolateral of door, sketch map when opening the door.

Fig. 2: be that the present invention does not have folding door in the axle, the observer is positioned at the proceeds posterolateral of door, sketch map at closing time.

Fig. 3: be dead ahead, observe and do not have sketch map when folding door opens the door in the axle from door.

Fig. 4: be stator, moving plate combining structure sketch map.

Fig. 5: be the stator structural representation.

Fig. 6: be the moving plate structural representation.

Among the figure: 1, first door, 2, second door, 3, stator, 4, moving plate, 5, extension spring, 6, the garden arc chute, 7, bearing pin, 8, first, the centre of gyration line during second shutter door, 9, the extension spring hook.

The specific embodiment:

Embodiment: see Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6.Stator 3 is installed on first door 1, and moving plate 4 is installed on second door 2, and the garden arc chute 7 of stator 3 is a rotation with center 8; 4 two bearing pins 7 of moving plate are positioned on the garden arc center line of garden arc chute 7, and extension spring 5 hangs between extension spring hook 9 and the bearing pin 7, when with manual or mechanomotive force; Promote second door 2 when upwards opening; Because two bearing pins 7 of moving plate 4 slide in the garden of stator 3 arc chute 6, also promptly make second 2 wraparounds that are connected with moving plate change center line 8 revolutions, second 4 is opened; And can't see Hardware fitting and gyroaxis entity from the front of door, as shown in Figure 3.When at closing time with manpower or mechanomotive force, extension spring 5 can auxiliary pulling second 2 get back to and first 1 straight position, as shown in Figure 2, not having in the axle folding door also can level or install by other direction.

Claims

1. do not have in the axle folding door and be made up of first door, second door, stator, moving plate, bearing pin and spring, stator props up and is contained on first door, and moving plate is installed on second door; Moving plate is inserted in the garden arc chute of stator, when moving second with external force with two bearing pins on it; Second meeting is slided in the arc chute of the garden of first stator with two bearing pins of moving plate; Accomplish second shutter door action, the spring hook is arranged on stator, the groove or the hole that hang spring are arranged on the bearing pin of moving plate.It is characterized in that:

The arc center, garden of the garden arc chute of stator is exactly first centre of gyration during with second shutter door, and second two bearing pin centers must be on the arc center line of the garden of first garden arc chute.

2. like folding door in the right 1 described nothing axle, it is characterized in that:
