Description

Perambulator folds the mechanism of standing automatically

The utility model system is about a kind of perambulator, and particularly relevant a kind of perambulator folds the mechanism of standing automatically.

Pushchair oneself through be the modern, particularly friend women brings great convenience, and makes the baby no longer need to be embraced on hand or carry on the back at back.But, owing to can not uprightly place after folding, and make perambulator take many spaces, the convenient effect of perambulator is had a greatly reduced quality.

Therefore, the applicant submits the application of No. 99246467.6 " perambulator folds the mechanism of standing automatically " by name on December 8th, 1999 to Patent Office of the People's Republic of China.As shown in Figure 5, the automatic standing device 100 of this case comprises a pivotal axis 120 and and parks plate 140.When being used in perambulator, the two ends of parking device are connected to respectively on food basket pipe 160 and the hind axle 170, therefore, have hindered the user virtually at the convenience that uses the food basket (not shown), have also influenced the perambulator overall appearance simultaneously.Developed a kind of novelty mechanism of standing automatically, continuing to finish the function of standing automatically not hindering under the situation that food basket uses for this reason.

Therefore, the purpose of this utility model provides a kind of perambulator and folds the mechanism of standing automatically, and it can overcome the aforementioned mechanism of standing automatically and hinder the defective that food basket is used.

The technical scheme that realizes the purpose of this utility model is:

A kind of perambulator folds the mechanism of standing automatically, have a upper branch pipe in order to be connected to, once on the perambulator of breeches pipe and food basket, this mechanism of standing comprises that one has the connecting rod at two ends, its first end is connected to upper branch pipe pivotly, wherein, the described mechanism of standing also comprises a crank, and this crank roughly is leg shape, have a foot, a knee and in the bending of foot upper end links to each other with knee can the pivot mode to be connected to the joint of connecting rod second end; The knee of crank is by an anchor fitting can vertically be fixed to down pivotally breeches pipe, angle between described foot and the joint is arranged to when perambulator is opened, the foot of crank is received the position with following breeches pipe almost parallel, the length of described foot is arranged to when perambulator folds, and forms the bearing surface of this perambulator with trailing wheel.

The utility model has the advantages that the food basket that makes things convenient for perambulator uses, simultaneously, set up perambulator of the present utility model to fold to stand automatically mechanism not influence the overall appearance of perambulator.Other purposes of the present utility model, function and advantage will be by following detailed description and conjunction with figs. and become clearer, wherein:

Fig. 1 is the stand three-dimensional exploded view of mechanism of the utility model;

Fig. 2 is that the utility model mechanism of standing is incorporated into upper branch pipe and the following partial, perspective view between breeches pipe;

Fig. 3 is the utility model mechanism action scheme drawing of standing;

Fig. 4 is for using the stand lateral plan of mechanism of the utility model; And

Fig. 5 is the stand block diagram of perambulator of mechanism of traditional having.

See also Fig. 1, the application's the mechanism 10 of standing comprises a connecting rod 20, one cranks 30 and a permanent seat 40.First end 22 of connecting rod 20 be provided with a C shape section pipe clamp 24, the second ends 26 then with crank 30 can the pivot mode linking together.40 of permanent seats have a C shape section pipe 42, and in its curved outside place an one-body molded radial column bolt 44.The front end of this post bolt 44 has an inclined-plane projection 46.And the relative both sides of C shape section pipe 42 are formed with the hole 43 of some alignings, for the fixing usefulness of permanent seat 40.

Crank 30 roughly is a leg shape, have respectively a foot 32, the knee 34 and of the bending of foot 32 upper ends link to each other with knee 34 can the pivot mode to be connected to the joint 36 of connecting rod 20 second ends 26.Knee 34 has a hole, preferably horizontal expansion has a hollow tube 38, makes the radial column bolt 44 pass this hollow tube 38 knee 34 of crank 30 can be held between the projection 46 of permanent seat 40 and the C shape section pipe 42 and can pivot to strengthen the support strength of bent plate.

As shown in Figure 2, the application's the mechanism 10 of standing has been incorporated on the perambulator 150, and for the purpose of simply clear, perambulator has only part to be illustrated.Wherein, the C shape section pipe 24 of connecting rod 20 has been connected to the upper branch pipe 50 of perambulator 150 pivotly, C shape section pipe 42 then is fixedly connected to the following breeches pipe 60 of perambulator 150 with rivet 45, make perambulator 150 make C shape pipe 42 pivot with respect to following breeches pipe 60 in folding Shi Buhui.Certainly, rivet 45 also can substitute with screw.

In Fig. 3, illustrate when the perambulator (not shown) is folded, because the distance between upper branch pipe 50 (being shown in Fig. 2) and following breeches pipe 60 (being shown in Fig. 2) is elongated, make the connecting rod 20 in the application's the mechanism of standing upwards move, and then pulling joint 36 upwards, and the foot 32 of crank 30 is moved down, and be resisted against on the ground, thereby make perambulator to stand.And when perambulator folded, then joint 36 moved down, thereby made foot 32 withdrawal, shown in imaginary line, was in roughly the position parallel with following breeches pipe 60, and this can be by presetting the angle acquisition between joint 36 and the foot 32.

As shown in Figure 4, be the stand lateral plan of mechanism 10 of the application, wherein foot 32 is to be tilted to down extension, its length is arranged to after perambulator is regained, constitute the bearing surface of the application's perambulator with the double rear wheel 62,64 (being shown in Fig. 2) of perambulator, make that the perambulator after folding can be stood automatically.Wherein, obviously illustrate, this hollow tube 38 is to be held between the C shape section pipe 42 and inclined-plane projection 46 of permanent seat 40; Second end 26 bending in the joint that is connected to crank 30 36 of connecting rod 20 inwardly, to reduce and the contacting of food basket.

As shown in Figure 2, because the application's connecting rod 20 is one side of being fixed in upper branch pipe 50, thus the ease of use of user can not hindered fully for the food basket (not shown), simultaneously, because being major part, crank 30 hidden, so do not influence the outward appearance of perambulator itself fully by food basket.Therefore, the application's the mechanism's 10 existing practicality of standing are attractive in appearance again.

In aforementioned specification, the utility model is illustrated by specific embodiment.Yet, should be appreciated that, can under the situation that does not break away from spirit of the present utility model and scope, carry out various modifications or change.For example, permanent seat 40 can be replaced with a rivet, directly to pass the hollow tube 38 on the crank 30, is fixed to down on the breeches pipe 60.Therefore, specification sheets and accompanying drawing system are used as illustration, rather than are used to limit the utility model.
