Description

[Detailed Description of the Invention] The present invention relates to a self-supporting device for a folding stroller.

The object of the present invention is to provide a self-supporting device that allows a folded stroller to easily and accurately stand on its own at a desired location.

Another object of the present invention is to provide a self-standing device for a folding stroller that is easy to handle and does not interfere with the stroller when it is being used as a stroller.

Furthermore, another object of the present invention is to provide a self-supporting device for a folding stroller in which the standing leg rods are automatically folded when the folded stroller is unfolded for use. It is.

Embodiments of the present invention will be described below with reference to the drawings. The self-supporting device of the present invention is composed of a base plate 1, a leg lever 2, a leg lever erecting operation plate 3, and a leg lever retracting wire 4. The base plate 1 has a rising part formed by bending the side part, and the base plate 1 is placed at an appropriate position at the lower end of the folding stroller a, for example, at the rear leg levers 5, 5.
Its base end is fixed to the horizontal frame 5' that connects the
Approximately U is on the tip of the board 1 toward the back of the stroller.
The proximal end of the leg rod 2 bent into a letter shape is pivotally attached, and the distal end is pivotally attached so as to be freely movable. The stand-up operation plate 3 of the leg rod has a free end at its tip, and a base end pivoted to the front end of the stroller so that it can be freely raised and lowered, and has a swing hole 31 formed approximately in the center of the stand-up operation plate. A lateral extending portion provided by bending near the base end of the leg rod 2 is fitted in the leg rod 2 so as to be freely movable. Reference numeral 6 denotes a spring for supporting the pivoting of the leg rod 2, and the spring 6 stably holds the leg rod 2 at one end in either the use position or the storage position. In the embodiment, the base end of the substrate 1 is fixed together with the frame rod 7' of the basket 7 for storing small items, but the present invention is not limited to this. The leg rod retraction wire 4 is a flexible thin metal wire or the like, and its one end is placed at an appropriate position near the base end of the leg rod 2, for example, near the fitting part with the standing operation plate 3. etc., and the other end is connected to a member, for example, a horizontal frame 5', which moves in the direction of pulling the leg rod 2 into a non-use position when the stroller a is set in a used state. Furthermore, stroller a may have any structure, for example,
As described in Japanese Patent Application No. 25980, it is possible to freely use a device that can be folded into a cane shape or a rod shape using a known folding structure.

The present invention constructed as described above operates as follows. That is, when the stroller is being used as a stroller, the leg rod 2 is laid down horizontally with the grounding end lifted upward, as illustrated in FIGS. 2, 4, and 5. Particularly in this case, since the leg rod 2 is constantly pulled up by the pull-in wire 4, there is no fear that the leg rod 2 will suddenly stand up and touch the ground while the stroller is in use, causing the stroller to overturn.

When you want to operate the self-standing mechanism after folding the stroller a, press down with the free end of the stand-up operating lever 3, and the leg lever 2 in the position shown in FIGS. It stands up while being guided by the floating hole 31, and finally stands upright with the leg 2 substantially perpendicular to the base plate 1 as shown in FIGS. 1 and 3. If the lower end of this upright leg lever 2 is grounded, the stroller a can stand on its own as shown in FIG.

If you want to use the folded stroller again, unfold the stroller a from the folded state, and the retractable wire 4 will be retracted as the horizontal rod 5' moves, and the leg rod 2 connecting its end will automatically open. The leg lever 2 can be stored in a reclined position, and there is absolutely no need to forget to fold down the leg rod 2 when it is erected.

Claims (1)

[Scope of Claim for Utility Model Registration] A self-supporting device for a stroller that is attached to the lower end of a stroller a that is foldable and cannot stand on its own when folded, and that makes it possible to stand on its own with leg levers 2 when folded, which comprises: a base plate 1 and a leg lever 2; The board 1, which is made up of the stand-up operation plate 3 of the leg lever 2 and the pull-in wire 4 of the leg bar, and has a rising part formed by bending the side part, is fixed at an appropriate position at the lower end of the stroller a, and The proximal end of a leg rod 2 bent into a substantially U-shape is pivotally attached to the distal end, allowing the distal end to be freely movable. The stand-up operation plate 3 has a free end at its distal end, and a base end pivoted to the front end of the base plate 1 in the front direction of the stroller so as to be freely movable, and has a floating hole formed almost in the center of the stand-up operation plate. 31, a lateral extending portion provided by bending near the base end of the leg rod 2 is fitted in a freely movable manner, and the leg rod 2 is stably held in either the use position or the storage position by the spring 6. . The retractable wire 4 of the leg rod 2 has one end connected near the base end of the leg rod 2, and the other end connected to the stroller a.
It is connected to a member that moves in the direction of retracting the leg rod 2 to the non-use position by the operation of setting the leg rod 2 to the use state. A self-supporting device for a folding stroller, which is characterized by:
