Can find out that each abutting

end

3a, 3b comprise

coupling device

5a, 5b and

locking device

6a, 6b separately.Rely on separately linkage 8a, the 8b that in scaffold element 2, extend, each

locking device

6a, 6b are connected with drive unit 7.

Linkage

8a, 8b are preferably the stiffener such as smooth metal, bar or a homologue.Drive unit 7 comprises two releasing

device

10a, 10b and executive component 11.Executive component 11 comprises two

rotating mechanism

50a, 50b, and wherein each all comprises separately the

first end

53a, 53b and separately the

second end

54a, 54b, and each all is set to around separately

rotation

55a, 55b rotatable.Executive component 11 further comprises two coupling mechanism 51a, 51b, and wherein each all is a line, but also can be such as bar or knuckle rod.Selectively,

linkage

8a, 8b and corresponding coupling mechanism 51a, 51b can be integral member.Rely on separately

linkage

8a, 8b, separately end 52a, the 52b of each releasing

device

10a, 10b is connected to rotating mechanism 50a separately, separately the first end 53a, the 53b of 50b.Each

rotating mechanism

50a, 50b and then be connected to two coupling mechanism 51a, 51b; Make coupling mechanism 51a that the first end 53a of rotating mechanism 50a is connected with the second end 54b of rotating mechanism 50b, coupling mechanism 51b makes the second end 54a of rotating mechanism 50a be connected with the first end 53b of rotating mechanism 50b simultaneously.

Through this layout, drive unit 7 is set to be positioned at the common drive mechanism on the interlude 4 of scaffold element 2, and two releasing

device

10a, 10b are suitable for discharging simultaneously locking

device

6a, 6b separately respectively.Selectively, drive unit 7 is set to the common drive mechanism in the interlude 4.

Thereby when among operation releasing device 10a, the 10b any one with drive unit 7 and with its parts when latched position is taken the off-position to; The user only uses one hand to push releasing

device

10a or 10b possibly, to discharge two abutting end 3a, the locking device 6a at 3b place, the 6b that is positioned at scaffold mechanism simultaneously.In further detail; With releasing device 10a as an example; Releasing device 10a is impelled around rotation 20a to rotate; Thereby along direction towards the center of scaffold element, perhaps in other words along leaving locking device 6a and towards the direction of relative locking device 6b, promote-side 52a and thereby promote linkage 8a.

Therefore; Rotating mechanism 50a is around its rotation 55a rotation; Thereby promote coupling mechanism 51a and spur coupling mechanism 51b, realize the opposite rotation of whirligig 50b like this, towards the center pulling linkage 8b of scaffold element and the end 52b that therefore spurs releasing device 10b.Thereby; When operation releasing device 10a; Realize the conversion of the motion that moves to relative releasing device 10b of releasing device 10a, so that two

locking device

6a, 6b moved to off-position separately from separately latched position, thereby discharged separately locking device 6a, 6b.The realization of conversion of motion is, the rotation of whirligig 50a makes coupling mechanism 51a, 51b motion resist towards separately locking member 6a of the latched position prestretched of

locking member

6a, 6b, the prestretching force of 6b separately locking

member

6a, 6b applied pulling force.

When the user lets go to releasing device 10a; Spring force acts on

locking device

6a, 6b is last; Force it to get back to latched position, along spurring separately end 52a, 52b, thereby force executive component 11 to get back to its initial position towards abutting end 3a separately, the direction of 3b.

Can point out that two

linkage

8a, 8b can selectively be omitted, and end 52a separately, the 52b of each releasing

device

10a, 10b can directly be connected to rotating mechanism 50a separately, separately the first end 53a, the 53b of 50b like this.

Figure 11 a and 11b show the sectional drawing that can be used as the 5th embodiment of the scaffold mechanism that is positioned at locking and off-position that for example horizontal member 1a, diagonal 1b or railing element 1c use according to of the present invention respectively.The scaffold mechanism that in Figure 11 a and 11b, shows as horizontal member 1a and the difference of the scaffold mechanism among Fig. 2 a-e and the 3a-e only are executive component 11 and releasing device 10 configuration of drive unit 7 just.Therefore, have only these elements to be described below.

End

65a, 65b place that executive component 11 is included in separately are connected to separately linkage 8b, two support 60a of 8a, 60b.These two

support

60a, 60b comprise

62a, 62b and separately track 64a, 64b separately.Two

support

60a, 60b be installed in the interlude 4 of scaffold element 2 with round with pin 62a separately, the consistent transverse pivot axis pivot separately of longitudinal axis of 62b, and preferably process by metal such as aluminium.

Releasing device 10 comprises pin 61 and two track 63a, 63b; Wherein each track 63a, 63b holds and guide

62a, 62b separately; By this way; Allow separately support 60a, 60b round its transverse pivot axis rotation separately, and sell 61 and be positioned to all extend through simultaneously two

track

64a, 64b.

Thereby when operation releasing device 10 with drive unit 7 and with its parts when taking the position according to Figure 11 b to according to the position of Figure 11 a; The user only uses one hand to push releasing device 10 possibly, to discharge two abutting end 3a, the locking device 6a at 3b place, the 6b that is positioned at scaffold mechanism simultaneously.In further detail, push releasing device 10 caused sell 61 be pressed onto

support

60a, 60b above, cause

support

60a, 60b around by defined their pivotal line rotations separately of separately pin 62a, the 62b that in track 63a, 63b, guide.Therefore, the end 65a separately of

support

60a, 60b, 65b come to move away from each other, like this along the direction towards the center of drive unit 7, perhaps in other words along leaving locking device 6a separately, the direction of 6b, pulling
