Description

Singlehanded folding mechanism

Technical field

The utility model system is about a kind of singlehanded folding mechanism, especially is a kind of folding mechanism that can one-handed performance folds the perambulator skeleton.

Background technology

In general known perambulator, if fold the skeleton of perambulator, certainly will be with the handle supporting of holding with a firm grip on the other hand, and be located at clip mechanism on the skeleton by another manual manipulation, so that front-wheel support in the skeleton and rear wheel support are switched to stowed position mutually.

When user's is carrying object on hand or having the baby in arms, under the unmanned situation of seeking help, he or she can't fold the skeleton of perambulator with another hand.

The utility model content

Therefore, for solving the shortcoming of above-mentioned known perambulator, the purpose of this utility model is to provide a kind of singlehanded folding mechanism, and this one hand folding mechanism comprises a housing, a button and a pair of latch, is characterized in:

This housing comprises loam cake and lower cover, can be combined into one by fixed mechanism, and the surperficial within it correspondence position transversely of each lid is formed with the left and right chute of a pair of adjacency;

This button can be contained in this housing with longitudinal sliding, and this button is provided with a pair of skewed slot that vertically runs through sliding surface; And

This passes a pair of skewed slot of this button respectively to latch system, and its two ends system is contained in respectively in the corresponding chute of this upper and lower cover slidably, and this connects the long-range line that folds that folds the joint of a control respectively to latch;

When pushing this enclosure interior when pushing this button and vertically moving, cause this that latch is done horizontal relatively moving and drive this and fold line.

Above-mentioned singlehanded folding mechanism comprises a safety lock in addition, is articulated on the outside face of lower cover, and this safety lock comprises a teat and a press section, is provided with spring member so that elastomeric pushing can be done with respect to lower cover in this press section between this press section and following exterior surface; This button lower external face is formed with a groove, so that the teat of safety lock snaps in this groove by the elastic force of spring member.

According to another embodiment of the present utility model, a kind of singlehanded folding mechanism is provided, comprise a housing, a button and a pair of latch, be characterized in:

This housing has in order to hold the space that a pipe fitting laterally passes through, and this housing comprises loam cake and lower cover, can be combined into one by fixed mechanism, and the surperficial within it correspondence position transversely of each lid is formed with the left and right chute of a pair of adjacency;

This button has in order to hold the space that a pipe fitting laterally passes through, and can be contained in longitudinal sliding in this housing, and this button is provided with a pair of skewed slot that vertically runs through sliding surface; And

This latch system is passed this button respectively this to skewed slot, and its two ends system is contained in respectively in the corresponding chute of this upper and lower cover slidably, this connects the long-range line that folds that folds the joint of a control respectively to latch;

Be characterized in, push this enclosure interior by pushing this button and vertically move, cause this that latch is done horizontal relatively moving and drive this and fold line, therefore control the long-range joint that folds.

Singlehanded folding mechanism of the present utility model not only can use on perambulator, even uses on load-carrying vehicle that can fold or allied equipment.

The specific embodiment

With reference to Fig. 1 to Fig. 4, explain according to the singlehanded folding mechanism of the perambulator of the utility model embodiment.

Comprise loam cake 1, lower cover 2, button 3, safety lock 4 and two

latch

5a, 5b according to folding mechanism of the present utility model.

As shown in Figure 2, loam cake 1 has symmetrical shape with lower cover 2, and respectively covers left and

right chute

11a, 11b that 1,2 surperficial correspondence positions transversely are formed with two adjacency within it; 21a, 21b.Each covers 1,2 and has the preceding recess 14 that forms open front respectively; 24, reach left and right recess 15a, the 25a that forms left and right opening; 15b, 25b wherein form after two lids engage and can laterally hold the space that handle supporting pipe 62 passes left and right opening, as shown in Figure 3.Loam cake 1 inboard is provided with several bolt blocks 12, and lower cover 2 is provided with through hole 22 at the correspondence position with the bolt block 12 of loam cake 1, in order to by the fixing joint of upper and

lower cover

1,2 of bolt 63.

As shown in Figure 2, button 3 is to be the hollow housing shape with U-shaped cross section, and is contained in the preceding recess 14 of upper and

lower cover

1,2 slidably; 24 formed open fronts.This button 3 comprises front portion 31, top 32 and bottom 33.This upper and

lower part

32,33 has symmetrical left and right

skewed slot

34a, 34b respectively at its correspondence position; 35a, 35b.Respectively left and right skewed slot 34a, the 34b of this upper and

lower part

32,33; The relative angle system of 35a, 35b is towards these front portion 31 polymerizations.Be formed with a groove 36 on these bottom 33 outside faces.

Safety lock 4 is to make the button 3 that is used for locking in the perambulator running condition, and curved sheet and being articulated on the outside face of lower cover 2.This safety lock 4 comprises the teat 41 in the open front the place ahead that extends to upper and

lower cover

1,2 and is positioned at its latter half of press section 42.When perambulator lay in running condition, this teat 41 was to snap in the groove 36 of button 3, as shown in Figures 2 and 3.Be provided with spring member 64 so that elastomeric pushing can be done with respect to lower cover 2 in this press section 42 between this press section 42 and lower cover 2 outside faces.

As shown in Figure 2, two

latch

5a, 5b are that the mat steel wire is connected to clip mechanism, and wherein the two ends system of passing left skewed slot 34a, the 35a of button upper and

lower part

32,33 and this latch 5a of latch 5a system places the left chute 11a of upper and

lower cover

1,2 slidably; In the 21a, and right skewed slot 34b, the 35b of button upper and

lower part

32,33 passes in another latch 5b system and the two ends of this latch 5b are the right rail 11b that places upper and

lower cover

1,2 slidably; In the 21b.

By the combination of said modules, as shown in Figure 4, when perambulator lies in running condition following time, the teat 41 of safety lock 4 is to snap in the groove 36 of button 3 bottoms 33 outside faces.When desiring perambulator is folded, at first, push the press section 42 of safety lock 4 so that the teat 41 of safety lock 4 breaks away from the groove 36 of buttons 3, inferior person pushes button 3 in the open front of upper and

lower cover

1,2, by two

latch

5a, 5b at button skewed

slot

34a, 34b; Slip in 35a, the 35b with respect to two

latch

5a, 5b at upper and

lower cover chute

11a, 11b; Slip in 21a, the 21b causes two

latch

5a, 5b approaching opposite to each other, spurs clip mechanism by this and makes the skeleton that folds perambulator.Anti-is as the same, as shown in Figure 3, when the skeleton of perambulator is got back to running condition, two

latch

5a, 5b oppositely away from, the teat 41 that causes safety lock 4 snaps in the groove 36 of button bottom 33 outside faces owing to be located at the elastic force of the spring member 64 between safety lock press section 42 and lower cover 2 outside faces.

Though the foregoing description has explained relevant structure of the present utility model, characteristics and function.For those who familiarize themselves with the technology, after reading above explanation, can structurally make an amendment easily and change, yet these are revised with changing and still belong in the scope that the utility model claim scope contained.
