Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a stroller that can also be used as a shopping cart.

[Prior art and its problems]

Strollers for transporting infants are known to have various structures.

These strollers have a so-called stroller in which the angle of the relationship between the seat on which the infant sits and the backrest that supports the infant's back can be freely changed from a seated position to a lying position. It is known to have a reclining mechanism, and the hand push mechanism for moving the stroller is also one in which the push lever stands up on the back side of the infant and is pushed from the back side, or one in which the push lever is placed facing the infant. There are known devices in which the device is pushed while standing up in a direction and facing the infant.

However, since the main purpose of conventional strollers is to transport infants, it is not possible to store and transport luggage in the seat floor, and the accessory compartment attached to the bottom of the seat floor is also As the name suggests, it is nothing more than a ``accessory case'' and has insufficient functionality as a cross gauge space.
It was difficult to use it as a shopping car.

Also, as for shopping only, there are two-wheeled vehicles with two wheels attached under the storage compartment and pullers attached to them, and compact four-wheeled vehicles with relatively narrow wheel spacing and pullers similar to the above. Cart-type carts with attached carts are known, but because they were intended for transporting shopping items, they did not have any function for carrying infants.

In order to solve this problem, the applicant has developed a stroller in which a relatively large-capacity article storage body is suspended from the rear of the lower surface of the stroller body (Utility Application No. 62-23848). )
Although this has solved many of the drawbacks of conventional strollers, this invention still has the following drawbacks. In other words, when folding and storing an article container suspended behind the lower surface of the stroller body (a bag made of a net-like cylinder is attached between a hanging frame and a bottom plate having an appropriate weight), the lower surface of the bag Lift the bottom plate attached to the frame horizontally in the direction of the hanging frame so that they are close to each other, and in this state, hook the locking device attached to the rear end of the bottom plate to the formed hook formed on the back of the backrest of the stroller. Therefore, the closeness of the rear end side of the article container that was forcibly brought close to it is guaranteed, but the tip of the bottom plate, which has no special latching means, The hanging part on the rear end side is used as a hanging fulcrum to be hung vertically, and the hanging part is separated from the tip of the hanging frame, resulting in a wide gap between the two, resulting in an unsightly appearance. It will be revealed.

There was a drawback.

[Purpose of invention]

This invention was developed in view of the above circumstances, and it goes without saying that when there is no need to store items, the item storage part can be folded extremely compactly and stored. To provide a baby stroller which can be folded so that all surfaces of a bottom plate part constituting the body can be folded so as to be uniformly close to a suspension frame, and which can also be used as a shopping car.

[Key points of the idea]

The present invention has an article storage body that is suspended from the lower surface of the seat of the stroller to the rear thereof, the upper surface of which has a wide opening surface and is configured to be foldable and undulating freely, and the upper end of the article storage body between near the tip of the hanging frame attached to the section and near the tip of the bottom plate attached to the bottom surface of the article container.
A folding maintaining rod consisting of two links configured to be bent in a "dog" shape so that it can be folded in two only in a specific direction is installed across the frame, and the folding maintaining rod overlaps when folded in half. A locking protrusion is formed protruding from the link located on the front side at the part where the locking projection is bent in an L-shape with the tip facing inward, and the locking hook portion is located on the inside when superimposed. It is configured to be locked to the upper edge of the other link, and a locking tool that can be detachably locked to a locking hook provided on the back of the backrest is attached to the rear end of the bottom plate. The main idea behind the idea is a stroller that doubles as a shopping cart.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The stroller generally indicated by A is a known one, and in the figure, 1 is a front leg lever, 2 is a rear leg lever,
The two leg rods 1 and 2 are connected to the armrest rod 3 at the upper end.
The two leg rods 1 and 2 are pivotally connected via a pivot to the tip thereof, and the distance between the two leg rods 1 and 2 can be opened and closed in a lateral 8-shape by opening and closing operations.

4 is a hand lever formed in a U-shape from the front;
Its base end is pivotally attached to the tip of a folding operation bracket 41.

The folding operation bracket 41 has a substantially L-shaped side surface, and its lower end, which is attached parallel to the rear leg lever 2, is pivoted to the rear leg lever 2, and the lower end of the push lever 4 is attached to the rear leg lever 2. The tip of the attached shaft is the back surface of the shaft of the rear leg lever 2 (the upper surface of the shaft along the length direction)
It is arranged so that it abuts parallel to the .

Furthermore, the lower end of a support rod 31 that is located inside the hand rod 4 and supports the rear end of the armrest rod 3 while being parallel to the hand rod 4 is pivotally attached to the tip of the folding operation bracket 41. . The base end portion of the armrest rod 3 is pivotally attached to the upper end of the support rod 31.

The folding operation bracket 41 is configured so that it can be turned over below the rear leg lever 2 using the lower end pivoting portion as a fulcrum when performing a folding operation.

Reference numeral 5 denotes a seat floor plate attached to both sides of the front leg lever 1 and the rear leg lever 2. At the rear end of the seat floor plate 5, a back plate 6 made of hard synthetic resin or the like is attached to the side surface. It is pivoted so that it can rise and fall freely to form an L-shape.

Reference numeral 61 denotes a locking rod that extends on both sides of the back surface of the back support plate 6 in order to adjust the inclination angle of the back support plate 6, and the intermediate portion thereof is located at a predetermined locking position ( (not shown) so that the inclination angle of the back plate 6 is determined.

Note that the detailed structure of the stroller described above is not essential to the present invention; the seat and backrest are attached to the rear end so as to form an L-shape on the side, and the wheels are attached to the lower end of the stroller. It may be of any structure as long as it is supported by a leg rod having a diameter and is moved by a push rod.

Reference numeral 7 denotes an article storage body constructed using relatively hard cloth such as canvas or mesh fabric, and is constructed as a deep box-shaped container with an open top.

A hanging frame 71 formed in a U-shape in plan is attached to the upper end opening of the article storage body 7 to maintain the shape of the opening. It is pivotally connected to a supporting bracket 72 suspended from the rear end so as to be able to rise and fall freely.

In addition, a locking tool 8 is provided at the bottom of the article storage body 7 to maintain the shape of the deep box-like container.
In order to make it convenient to install, a bottom plate 73 is attached which has a shape-retaining property and has an appropriate thickness and weight.

The locking tool 8 is formed using a hard synthetic resin or the like, and has a horizontally elongated fitting groove near the tip of the substrate 81, as illustrated in detail in FIGS. 1, 2, and 5. 82 is bored and this fitting groove 82 is attached to the back surface of the back plate 6.
This makes it possible to engage with

Reference numeral 83 denotes a locking protrusion formed at the tip of the bottom plate near the base plate 81, and is fitted into a fitting hole 91 drilled in the step plate 9 extending between the rear leg levers 2, 2. This prevents the article storage body 7 from rolling or other movements.

In addition, in the embodiment, the locking hook 63 is attached to the back plate 6.
Although the structure is illustrated as being attached to the inclination angle adjustment plate 61 attached to the back surface of the camera, the structure is not limited to this.

Further, the structure of the back support plate 6 is not limited to that shown in the embodiment, and for example, the back support part may be made of cloth instead of the hard synthetic resin shown in the example. In this case, a locking hook 63 may be attached to an appropriate position on the back of the fabric backrest.

Reference numerals 10 and 10 designate links for maintaining folding that are pivotally connected between the hanging frame 71 formed in a U-shape in plan and the bottom plate 73 that constitute the article storage body 7, and are relatively flexible so as to be able to bend appropriately. By pivoting both ends of two links 10, 10 formed of hard synthetic resin, a link mechanism is constructed in which the central portion can be folded in half.

Reference numeral 11 denotes a locking protrusion formed on the link 10 located on the front side when stacked, the upper end protruding slightly above the edge along the length direction of the link 10, and the protruding tip portion It is configured as a locking hook portion 12 bent inward in an L-shape.

It is desirable that the upper surface of the locking hook portion 12 has a so-called "enterable" structure that forms an inclined surface toward the tip, as illustrated in the enlarged view of FIG. During the folding operation of the link 10, it is ensured that the upper end of the locking projection 11 folds without getting caught on the underside of the link 10 located inside.

In the embodiment, the locking protrusion 11 is formed integrally with one of the links 10, but the present invention is not limited to this.
For example, it is also possible to form only the locking protrusion 11 separately and integrate it with the separately formed link 10 by pasting or screwing means.

In addition, a stopper 13 is provided at the central part where the two links 10, 10 are pivotally connected, which can be folded into a dogleg shape only when facing in one direction, and prevents it from being bent in the opposite direction. It is desirable to form a

To open the article storage body 7 in the folded state, perform the opposite operation to the above-mentioned operation, that is, hook your finger on the locking portion 83 at the rear end of the bottom plate that is in the hooked state and lift it upward.

The above-described lowering operation of the bottom plate 73 causes the two links 10, 10 in the hooked state to be deflected, and the deflection of the links 10, 10 is due to the overlap between the locking hook portion 12 and the link 10. to release the lock.

When the locking by the locking protrusion 11 is released, the article storage body 7 hangs downward due to its own weight, and can instantly form a deep square bottom shape.

[Effect of idea]

The effects of the present invention configured as described above are as follows.

(1) In the stroller of the present invention, when carrying an infant and storing and transporting baggage at the same time, or when carrying only baggage alone, the stroller of the present invention can be used as shown in FIG. This purpose can be easily achieved simply by leaving the top opening open.

(2) If it is not necessary to store or transport cargo,
After releasing the engagement between the locking plate 83 attached to the rear end of the bottom plate 73 of the article storage body 7 and the fitting hole 91 provided in the step plate 9, lift the bottom plate 73 upward while holding the locking plate 83. When the pull-up operation is performed, the part of the bottom plate 73 including the net-like bag comes close to the hanging frame 71, so a groove 82 for fitting the board 81 attached to the tip of the bottom plate 73 is formed in the backrest part 6. By fitting the locking hook 63, the folding of the article storage body 8 can be completed.

(3) If only the above-mentioned folding operation is performed, the tip of the bottom plate and the tip of the hanging frame 71 will still be separated, so the lower end of the bottom plate 73 should be pushed up in the direction of the hanging frame 71. do.

By the above operation, the bottom plate 73 and the hanging frame 7 are removed.
1 approach each other while maintaining a horizontal state, the two-folded links further move toward each other, and as a result, the locking protrusion 11 formed on the front link 10 engages the side edge of the inner link 10 that overlaps with this. Eventually, the locking protrusion 1
A locking hook portion 12 bent at the tip of one link can engage with the other link to integrate the two.

(4) With the above configuration, the hanging frame 71 and the bottom plate 73 are compressed thinly so that the entirety thereof maintains a horizontal state, and can be folded compactly.

(5) In the present invention, the folding maintenance links 10, 10, which can be folded freely in two, are placed between the hanging frame 71 and the bottom plate 73, and the two links 10, which are in a superimposed state, Since a locking protrusion 11 having a locking hook portion 12 is formed on the link 10 located on the front side of the links 10, the two links 10, 10 in the folded state can be kept in their overlapping state by the locking protrusion 11. In order to be maintained, the bottom plate is superimposed while maintaining a horizontal state on all sides from the rear end to the front end, and the front side of the bottom plate, which was included in conventionally known article storage bodies, hangs down. This has the extremely excellent effect of completely preventing such unseemly situations from occurring.
