Description

  The present invention relates to a baby carriage, and the seat part (4, 10) and the frame 2 are directly folded, and the operation is simple and quick, and the seat part is directly folded on the frame, so that the folding volume is increased. It relates to a relatively small structure.

  As shown in FIGS. 1, 2, and 3, the known baby carriage is provided with an independent seat base 1 on a frame and combined with the seat portion, so that the direction of the seat portion can be easily changed. However, since the seat part protrudes from the frame, the size (folding volume) becomes excessive (high) when folded, and as shown in FIG. 4, it becomes inconvenient to carry or carry, and the seat part is rearward. (Fig. 3), the sheet part interferes with the frame and cannot be folded directly. For this reason, before folding, the sheet part must be removed first before folding. It is cumbersome and cumbersome, and since the frame and the seat part are separated into two parts when folded, it becomes easy to lose and the inconvenience during transportation and carrying increases.

  An object of the present invention is to provide a baby carriage in which a seat portion is directly folded on a frame and a folding volume is reduced.

  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

  Further, at the time of folding according to the present invention, the folding volume can be further reduced. This is because a folding joint 6 is provided in the seat portion 4, and the seat portion 4 is a cloth sheet 41 as shown in FIGS. The folding joint 6 is provided between the upper seat pipe 42 and the lower seat pipe 43, is fixed to the bottom end of the upper seat pipe 42, and corresponds to the outer surface. An upper joint 61 having a notch 611, two fixed blocks 62 placed in the notch 611 by a spring 621 and constantly biased upward, and provided on the outside of the upper joint 61, A pressing piece 63 provided with a notch 631 corresponding to the fixed block 62, and an upper end of the lower pipe 43 of the seat, which is integral with the fitting sheet 40; Positioning grooves 641 (see FIG. 7) corresponding to the side surfaces are provided, correspond to the two fixing blocks 62, and are connected to the upper joint 61 by fixing parts 65 (rivets or the like). Is located outside the upper pipe 42, and a slide block 67 is connected to the bottom end of the lower joint 64. The slide block 67 is positioned in the sliding groove 421 of the upper pipe 42. (FIG. 8) A lever 66 is provided inside the on-seat pipe 42, one end is fixed to the push piece 63, a spring 69 is fitted to the outside, and the other end is fixed to the slide block 67. An interlocking component 68 (such as a wire).

  With the above-described structure, when the seat portion 4 is opened, the fixed block 62 is engaged with the notch 631 of the lower joint 64 as shown in FIG. 5, as shown in FIGS. When folding, the lever 66 is simply rotated to drive and rotate the push piece 63 with the slide block 67 and the wire 68. At the same time, the push piece 63 rotates, and at the same time, the slope on one side of the fixed block 62 is pressed and fixed. The block 62 moves downward and is detached from the notch 611 of the lower joint 64. At this time, when the upper seat pipe 42 is turned downward, the upper joint 61 is rotated and the seat portion 4 is folded. 11 and can be directly folded without removing the seat portion 4 to reduce the half length (height).

  The left and right folding joints 6 of the above-described seat portion 4 are designed so that each portion operates independently, so that the user cannot fold it unless it is operated at the same time, and the user's erroneous operation can be prevented.

  When the user does not apply force to the lever 66, the fixed block 62 and the pushing piece 63 return to their original positions automatically rotated by the release tension of the spring 621. At this time, the pipe 42 on the seat is further moved. When deployed upward, the fixed block 62 automatically engages with the notch 611 of the lower joint 64, the seat portion 4 is deployed and positioned, and returns to the state shown in FIG.

  Please also refer to FIGS. These show another embodiment of the folding joint of the present invention. The folding joint 7 is fixed to the bottom end of the seat upper pipe 42, and is placed in the notch 711 by an upper joint 71 having a notch 711 on the outer surface and a spring 73, and is always rotated outward. The fixed block 72 urged and fixed to the upper end of the lower pipe 43 of the seat are provided with two positioning grooves 741 corresponding to the inner surface, and are connected to the upper joint 71 by a fixing component 75 (rivet or the like). 72, a lower joint 74 fixed inside, a push button 76 provided at the middle of the upper end of the upper seat pipe 42 and a slide block 77 at the bottom, provided inside the upper seat pipe 42, and one end Is fixed to the fixed block 72 and the other end is fixed to the slide block 77, and an interlocking part (such as a wire 78), and the slide block It encompasses adjusting screw 79 to be subjected to adjust the length of the screwed wire 78 to click 77, or more.

  When the seat portion 4 is opened, the fixing block 72 and the positioning groove 741 of the lower joint are engaged and fixed, and when folded, if the push button 76 is simply pushed inward, the slide block 77 and the wire 78 are used. The fixed block 72 is driven to rotate, the fixed block 72 moves inwardly and is disengaged from the positioning groove 741 of the lower joint, and then the seat portion 4 is folded by turning the seat upper pipe 42 downward, FIG. It is as FIG. 15, FIG. 16, and can reduce half length (height) by this. On the other hand, when the user does not press the push button 76, the fixed block 72 returns to the original position by the tension of the spring 73, and then the pipe 42 on the seat is rotated upward so that the fixed block 72 is moved to the lower joint. By being fitted in the positioning groove 741, the seat portion 4 is positioned in the unfolded state, as shown in FIGS. 5, 13, and 14, and achieves the same operational effects as the above-described embodiment.

  The above description is only an example of the present invention, and does not limit the scope of the present invention. Any equivalent changes and modifications that can be made based on the scope of the claims of the present invention are all described in the present invention. Shall belong to the scope covered by the rights.
