Description

[Detailed Description of the Invention] Field of the Invention This invention relates to a frame structure of a foldable sunshade cover for a baby carriage.

Background of the invention This type of frame structure generally consists of a rear frame that is fixedly attached, a front frame that is rotatably attached, and a connecting member that connects the rear frame and the front frame. Provided as a component. The rear frame and the front frame are, for example, U-shaped. FIG. 1 is a side view schematically showing an example of a conventional frame structure. In the figure, the rear frame 1 is fixedly attached to the fulcrum 2, and the front frame 3 is rotatably attached to the fulcrum 2. The rear frame 1 and the front frame 3 are connected via a connecting member 4. The connecting member 4 is configured to be bendable about a fulcrum 5, and is rotatable relative to the rear frame 1 and the front frame 3 at fulcrums 6 and 7, respectively. When the connecting member 4 is fully extended as shown in FIG. 1, the distance between the rear frame 1 and the front frame 3 is the largest.
That is, this state is the open state of the sunshade cover. When folding this sunshade cover, if the front frame 3 is pressed backward, that is, in the direction shown by arrow A, the connecting member 4 is bent as shown in FIG. The distance from frame 3 is small. In this way, a folded state of the sunshade cover is obtained.

If there is a drawback in the frame structure of such a conventional sunshade cover, it is in the connecting member 4. That is, since the connecting member 4 is configured to bend upward or downward, the side surface of the frame structure looks complicated. This also brings about the following disadvantages. In other words, the entire frame structure shown in the figure is covered with the hood cloth, but in that case, the connecting member 4 may become entangled with the hood cloth as the connecting member 4 bends. Ta.

Purpose of the invention Therefore, the object of this invention is to provide a new frame structure for a sunshade cover that has a sleek appearance and features connecting members that do not have the above-mentioned drawbacks. .

Structure and Effects of the Invention The frame structure of the sunshade cover for a baby stroller according to this invention includes a rear frame that is fixedly attached to the baby carriage body, a lower end that is rotatably attached to the baby carriage body, and an upper end that is lower than the rear frame. a front frame positioned at the front; a connecting member having a rear end rotatably attached to the rear frame and connecting the front frame and the rear frame so as to allow rotation of the front frame; Equipped with. Here, when the front frame rotates forward and moves to the farthest position from the rear frame, the open state of the sunshade cover is obtained, and when the front frame rotates backward and moves to the position closest to the rear frame. The folded state of the sunshade cover is obtained when the sunshade cover is moved up to .

The feature of this invention lies in the connecting member.
That is, the connecting member is formed with an opening extending through almost the entire length thereof. The front frame extends through this opening. The opening includes a front region located at the front, a rear region extending from the center to the rear, and a narrow region located between the front region and the rear region and having an opening width narrower than both regions. Can be divided. The opening width in the narrow region is narrower than the thickness of the front frame. Therefore, when the front frame is located within the front region, the narrow region imposes a resistance to rearward rotation of the front frame. In this way, the open state of the sunshade cover is maintained.

On the other hand, if the front frame located within the front area is pushed backwards with a force greater than a predetermined value, the narrow area is pushed wide by the front frame to widen the opening width, and thereby the front frame Transition from the anterior region to the posterior region is permitted. When the front frame is further rotated rearward, the front frame moves within the rear region to the position closest to the rear frame, thus obtaining the folded state of the sunshade cover.

As described above, according to this invention, the open state of the frame structure of the sunshade cover is obtained by positioning the front frame within the front region of the opening formed in the connecting member, and the folded state is a configuration obtained by moving the front frame inside the opening of the connecting member, so the operation of the connecting member is simple, and the external appearance of the side of the frame structure is simple. It becomes what it is.

DESCRIPTION OF EMBODIMENTS FIG. 3 is a side view showing an example of a baby carriage equipped with a frame structure of a sunshade cover according to the present invention.

The baby carriage 10 basically includes a handrail 11, front legs 13 having a front wheel 12, rear legs 15 having a rear wheel 14, and a seat support rod 16 for supporting the seat.
, the lower end is connected to the rear leg 15 and the upper part is connected to the handrail 1.
1, and the baby carriage 10.
and a push rod 18 used when moving the. A bracket 19 is attached to the handrail support rod 17, and a backrest support member 20 and a backrest support rod 21 are attached to this bracket 19. A sunshade cover 22 is attached to the upper end of the handrail support rod 17. This invention relates to the frame structure of the sunshade cover 22, but this frame structure is not clearly shown in FIG. 3 because it is covered by the hood cloth 23.

FIG. 4 is an enlarged side view of the sunshade cover shown in FIG. 3, with the top cloth removed to reveal the frame structure according to this invention. FIG. 5 is a perspective view of the frame structure shown in FIG. 4.

In the figure, the frame structure of the sunshade cover is
It includes an inverted U-shaped rear frame 24, an inverted U-shaped front frame 25, and a connecting member 26 as basic components. The rear frame 24 is fixedly attached via pins 28 to a frame support member 27 that is fixed to the upper end of the handrail support rod 17. The lower end of the front frame 25 is rotatably attached to the frame support member 27 via a pin 28. The rear end of the connecting member 26 is rotatably attached to the rear frame 24 via a pin 29. This connecting member 26 connects the front frame 25 and the rear frame 24 so as to allow rotation of the front frame 25, and its specific configuration will be described later. In the frame structure shown, when the front frame 25 rotates forward, that is, to the left in FIGS. 4 and 5, and moves to the farthest position from the rear frame 24, the sunshade cover is in an open state. It will be done. Then, the front frame 25 is positioned rearward, that is, as shown in FIGS. 4 and 5.
When the sunshade cover is rotated to the right in the figure and moved to the position closest to the rear frame 24, the sunshade cover is in a folded state. The state shown in FIGS. 4 and 5 is the state in which the sunshade cover is open.

FIG. 6 shows the rear frame 24 and the front frame 2.
5 is an exploded perspective view showing a frame support member 27 that supports the handrail support member 5 and the upper end portion of the handrail support rod 17 to which the frame support member 27 is attached. FIG. As shown, frame support member 27
has a notch 30 for rotatably receiving the front frame 25 and a receiving hole 31 for fixedly receiving the rear frame 24. When fixing the frame support member 27, the lower portion 32 of the frame support member 27 is inserted into the inner diameter hole 33 of the handrail support rod 17. Although not shown, the upper end of the handrail support rod 17 and the lower portion 32 of the frame support member 27 are fixed, for example, with a suitable pin. The frame support member 27 is preferably removable from the upper end of the handrail support rod 17. In this way, when the sunshade cover is not needed, the entire sunshade cover can be easily removed from the baby carriage by simply removing the frame support member 27 from the handrail support rod 17.

As previously mentioned, the feature of this invention is the connecting member 26. FIG. 7 is a sectional view of this connecting member 26 viewed from above. Connecting member 26 is made of a flexible material, such as plastic. As shown in the figure, an opening 34 is formed extending over almost the entire length thereof in the vertical direction, that is, in the direction indicated by arrow B in FIG. As is clear from FIGS. 4 and 5, the front frame 25 extends through the opening 34. As shown in FIGS. The opening 34 has a front region 35 located at the front, a rear region 36 extending from the center to the rear, and is located between the front region 35 and the rear region 36 and has an opening width larger than both regions 35 and 36. It is divided into a narrow region 37. The opening width in the narrow region 37 is narrower than the thickness of the front frame 25. Therefore, the following actions or conditions are achieved. This will be explained using FIGS. 8 to 10.

8 to 10 are cross-sectional views of the connecting member 26 and the front frame 25 located in the opening 34 of the connecting member 26, viewed from above, and the front frame 25 is located inside the opening 34 of the connecting member 26. It sequentially shows the forms that move through the interior.

As mentioned above, the opening width of the narrow area 37 is narrower than the plate thickness of the front frame 25, so when the front frame 25 is located within the front area 35 of the opening 34 as shown in FIG. , the narrow region 37 imposes resistance to rotation of the front frame 25 toward the rear, ie in the direction indicated by arrow C in FIG. In this way, the open state of the sunshade cover is maintained.

The connecting member 26 is made of a flexible material, such as plastic, so that when the front frame 25 located in the front region 35 of the opening 34 is pressed rearwardly, the narrow region 37 of the opening 34 is pressed. is pushed wide by the front frame 25 to widen its opening width. In this way, the front frame 25
is allowed to move from the front region 35 to the rear region 36. This state is shown in FIG.
Note that, in order to facilitate this transition, the boundary between the narrow region 37 and the front region 35 is preferably sloped.

From the state shown in FIG. 9, the front frame 25
If you rotate it toward the rear, the front frame 25
moves within the rear area 36 to the position closest to the rear frame 24. FIG. 11 shows the state during this movement from the side. As shown, at the same time that the front frame 25 rotates rearward, that is, in the direction indicated by arrow D in FIG. 11, the connecting member 26 rotates downward, that is, in the direction indicated by arrow E. In this way, when the front frame 25 is closest to the rear frame 24, the folded state of the sunshade cover is obtained. FIG. 12 is a side view showing this state. In order to stably maintain the folded state of the sunshade cover, the opening width of the rear end portion 38 of the rear region 36 is made larger than the thickness of the front frame 25, as shown in FIGS. It may be made slightly narrower. In this way, the front frame 25 can be attached to this rear end portion 38.
When located inside, the front frame 25 and the connecting member 2
6, the folded state of the sunshade cover is maintained. Further, as another example, the opening width of the entire rear region 36 may be made slightly narrower than the thickness of the front frame 25.

Next, when shifting the awning cover from the folded state to the opened state, the above-mentioned order can be followed in reverse, and since the basic operation is the same, the explanation thereof will be omitted.

The frame structure described above is covered by a canopy. In this case, care must be taken to ensure that the movement of the connecting member 26 is not obstructed by the hood cloth. For this reason, the following considerations are made when installing the canopy. This will be explained using FIG. In FIG. 4, the hood cloth is indicated by imaginary line 39. The front part 39a of the hood cloth 39 is fixed to the front frame 25, and the rear part 39b is fixed to the rear frame 24.
Fixed. However, fixing to the front frame 25 is limited to the section indicated by F in FIG. In the section indicated by G in FIG. 4, the hood cloth 39 is not fixed and is in a free state. Therefore,
Even if the connecting member 26 rotates downward, its movement is not hindered by the hood cloth 39.

In the above description, the connecting member 26 is rotated downward when the sunshade cover is moved from the open state to the folded state, but it may be rotated upward. . In this case, needless to say, the front part 39a of the top cloth 39 is in a free state in section F in FIG. 4.

Further, in the above-described embodiment, the front frame 25 and the rear frame 24 are described as having an inverted U shape, but it goes without saying that the shapes are not necessarily limited to this shape.
