安全でかつ軽量でその上機能的なベビーカーの発
表が望まれていた。 Various strollers have been released so far, but many of them require extra link mechanisms to enable one-touch operation to expand and fold them, which adds weight and makes them inconvenient to carry. On the other hand, in order to achieve a significant weight reduction, such an operating mechanism was omitted, making folding and unfolding operations difficult. In addition, many known baby strollers require locking after being expanded, and accidents have occurred due to poor or forgotten locking. Moreover, it was hoped that a more functional stroller would be released.

本考案は出来るだけ少数の部材でもつて極めて
容易かつ迅速な拡開及び折たたみ作業を可能とな
し、その上非常に竪牢で安全なベビーカーを提供
することを目的としている。 The object of the present invention is to provide a stroller that can be expanded and folded extremely easily and quickly using as few parts as possible, and that is also extremely sturdy and safe.

カーを提供する。 Furthermore, the present invention essentially eliminates the need for locks, which have always been a problem in hitherto known strollers, and the weight of the infant is always acting directly on the wheels, thereby preventing the infant's To provide a stroller configured so that its weight itself forces an expansion action.

また本考案は、ベビーカーの重量に抗して所定

その他の適当な方法により固着保持されている。 As shown in FIG. 3, on the other side of the front repellent fitting 88, there is a central tension member 1 which, although not essential, limits the expansion of the front legs and rear legs in the front-rear direction.
Holes 92, 94 are provided to accommodate one end of each. Note that the one end of the central tension member can also be attached directly to the front legs 2, 4. The other end of the central tension member is supported by the rear legs 6, 8 via the connecting portions 54, 56. That is, although the connectors shown in FIG. 2 only show one connector 56, the other connector 54 has the same effect except that its bending direction is different. Specifically, the coupling device 56 has a front leg receiving portion 96 having a generally U-shaped cross-section for receiving the front leg 4 at its left end in the figure, and a rear leg receiving portion 96 for receiving the central tension member 48 of the rear leg 8 at its upper end. It has 98. The rear leg receiving portion 98 is comprised of three parts, the left and right parts 100, 102 having a generally U-shaped cross section, while the central part 104 merely forms a rise. Left and right parts 100,1
02 is provided with pilot holes 106 and 108 passing through it, and these holes are aligned with the two tags provided on the side member 48, respectively, and are secured to each other by means such as pins. A hole 110 is also provided in the central portion 104. The hole 110 has a deformed U.
The rear ends of hammock holding members 112, 114, which have a letter-shaped shape and are arranged on the outside of the front legs 2, 4, are fixed with pins or the like. Note that the member 112,
The front end of 114 is fixedly held by fitting into the front ends of the rear legs 6, 8 or by other suitable methods.

Holes are provided at the inner ends of holes 2 and 24 at positions that align with holes 120 of the repellent fitting 118 bent into a U-shape as shown in FIG.
The members 22, 24 are pivoted to the fitting 18 by means such as a pin 122 extending through the fitting 18. The pin 122 is preferably provided with a support component 124 such as a hook or annular member;
This makes it easy to unfold and fold the stroller of the present invention, and also allows it to be stored in a suspended position.

本考案はかかる構成により次のように作動す

か、荷重が大きくなればなる程、前記クロス棒及
び中央張り部材が緊張し安定度が増すのである。 When an infant rides on a hammock (not shown) suspended from hammock holding members 112, 114, the weight of the infant is transferred to the hammock holding members 112, 114 and the rear legs 6,
8. Acts to pull the rear wheels 50, 52 and the front wheels 34, 36 apart from each other in the front-back direction through the front legs 2, 4, and the weight of the members 112, 114
A force is generated via the front legs 2, 5 and the rear legs 6, 8 that causes the legs to approach each other from the sides toward the center of the vehicle width. However, these actions and forces are applied to the central tension members 18, 20, the front repellent fitting 88, the front tension members 14, 16, which are prevented from rotating rearwardly along the central axis, and/or the front legs 2, 4, respectively.
and by the cross bars 10, 12, the rear tension members 22, 24 and the front tension members 14, 16. Therefore, when a small child rides on the stroller, the stroller of the present invention not only does not fold in, but the greater the load, the more tension the cross bar and central tension member become, increasing the stability.

向に接近する。 However, when the present invention is folded, the rear tension member 22, which is preferably in tension beyond the dead center,
It is only necessary to lift the 24 repelling fittings 118 or the hooks or annular portions 124 provided on the fittings 118. In other words, when the metal fitting 118 or the annular portion is lifted, the inner ends of the rear tension members 22 and 24 will touch the pin 122.
The outer ends of the front legs 2 and 64 pivot around the mounts 62 and 64 to pull them toward the center of the vehicle width.
4 approach each other. For this reason, the cross rod 10,1
2 pivots about pin 70 and rises toward the center, causing forward tension members 14, 16 to pivot forwardly and outwardly about fittings 80, 82 and 84, 86, respectively, as well as from fitting 62. 66, and 64 and 6
A force is generated that pulls the positions 8 apart from each other. Therefore, the front legs 2, 4 approach each other in the center direction, and the front wheels 34, 36 and the rear wheels 50, 52 approach each other in the longitudinal direction.

後方張り部材２２，２４がほぼ垂直に立上り、
前脚２，４が互いに接する程に接近すると析たた
み作動が完了する。 The rear tension members 22 and 24 stand up almost vertically,
When the front legs 2 and 4 come close enough to touch each other, the collapsing operation is completed.

のである。 On the other hand, to expand the stroller of the present invention, simply use the repellent fitting 118 or the hook 1 provided thereon.
Just press 24 downwards. This allows the expansion to be easily completed by the opposite action to the folding.

るのである。 The present invention does not require a special locking mechanism for complete expansion, as is the case with many conventional strollers. This is because when weight is added to the hammock, the stroller itself generates an expanding action. Accordingly, Moshiki metal fittings 1
Even if the bar 18 is lifted upward from its normal position during use, the weight added to the hammock forces the barge fitting to return to its normal position.
