  In general, strollers used for taking infants outdoors for walks, shopping, etc. should be folded as necessary to facilitate storage and carrying, and be in the back-handed state where they are pushed from the back of the infant. Various types have been proposed in which the user is in a face-to-face pressed state facing the infant.

  10 is a perspective view showing a schematic configuration of a conventional stroller, and FIG. 11 is a side view thereof, which includes a pair of left and right front legs 12 having a front wheel 11, a pair of left and right rear legs 14 having a rear wheel 13, A hand barb 15 bent in a substantially U-shape, a pair of left and right armrests 16, and two support pipes 17 extending in parallel to each other, each of which is pivotally attached to one end of the armrest 16, are provided.

  The upper end of the front leg 12 is pivotally attached to the other end of each armrest 16, and an arc-shaped bendable guard arm 18 is detachably suspended between the distal ends of the left and right armrests 16. In addition, the upper ends of the rear legs 14 are pivotally attached to the left and right armrests 16. The left and right front legs 12 are connected by a front connection bar 20 having a footrest plate 19, and the left and right rear legs 14 are connected by a rear connection bar 21. Further, the front end of the connecting bar 22 is pivotally attached to the middle portion of each front leg 12, and the rear end of the connecting bar 22 is pivotally attached to a rear leg support member 23 fixed to the lower portion of the support pipe 17. Yes. The left and right connecting bars 22 are connected by an upper connecting bar 24. The front leg 12, the rear leg 14, the armrest 16, the support pipe 17, and the connecting bar that connects them constitute a stroller body.

  As shown in FIG. 12, a lower end portion of an L-shaped bracket 25 is pivotally attached to the rear leg 14 by a shaft 25b, and an intermediate portion thereof is pivotally attached to the rear leg support member 23 by a shaft 25c. . A notch step portion 25 a that engages with a locking step portion 26 a of a lock member 26 that locks the rear leg 14 to the support pipe 17 is provided at the free end portion of the bracket 25. The lock member 26 is slidably mounted on the support pipe 17 and is operated to slide up and down along the support pipe 17 by a remote control device provided on the hand barb 15. Further, the rear leg support member 23 is formed with a step portion 23a on the surface facing the rear leg 14 so as to abut against the rear leg 14 at the time of deployment and maintain the deployed state.

  As shown in FIG. 12, when the lock member 26 is engaged with the notch step portion 25a of the L-shaped bracket 25, the rear leg 14 and the support pipe 17 are locked via the bracket 25, and the stroller body Is kept in a usable deployment state. On the other hand, when the lock member 26 is pulled up by the remote control device as shown by the one-dot chain line, the lock by the lock member 26 is released, and the armrest 16, the front leg 12 and the rear leg 14 are moved upward as shown by the one-dot chain line in FIG. It can be swung and can be folded in two for convenience of carrying.

  By the way, as shown in FIGS. 10 and 11, the rear leg support member 23 fixed to the lower portions of the left and right support pipes 17 has a lower end portion of a substantially U-shaped push bar 15 on its outer surface. Is pivotally mounted so that it can be swung back and forth, and by holding the push bar 15 in the rear position (solid line position), it can be pushed back, and the push bar 15 can be swung forward. By making it into the state (two-dot chain line) made it, it can be set as a facing hand pressing state.

On the other hand, the U-shaped push bar 15, the front connection bar 20, the rear connection bar 21, and the upper connection bar 24 are joints 15a ₁ , 15a ₂ , 20a ₁ , 20a ₂ , 21a at two locations in the middle part, respectively. ₁ , 21a ₂ , 24a ₁ , 24a ₂ are provided and can be folded by the joint. In each of the above joints, the axes of the joints 15a ₁ , 20a ₁ , 21a ₁ , 24a _{1 and} the axes of the joints 15a ₂ , 20a ₂ , 21a ₂ , 24a ₂ are in a state where the front leg 12 and the rear leg 14 are parallel to each other. When being folded into two, they are positioned on the same axis and are parallel to each other.

  After the front leg 12 and the rear leg 14 are folded so as to be in parallel with each other as described above, when the outer portion is moved forward from the joint of the hand bar 15, the hand bar 15 is connected to the front link by the joints. The outer portions of the bar 20, the rear connection bar 21, and the upper connection bar 24 are folded forward, so that the stroller can be compactly folded into a three-fold state with a U-shape in plan view as shown in FIG.

  However, in the above stroller, when folded in the above-mentioned two-fold or three-fold state, the area of the flat section, that is, the vertical and horizontal dimensions can be reduced, but the length of the hand barb is constant, so that it is folded as described above. Even in the state, there is a problem that the dimension in the height direction of the stroller is not reduced.

In view of this, it has been proposed that the straight pipe portion of the hand barb can be expanded and contracted so that when the hand barb is folded in two or three, the hand barb can be contracted simultaneously to reduce the height dimension.

  However, in general, in a stroller, in order to protect infants from sunlight, a awning hood 30 is attached as necessary as shown in FIG. 15, but when the stroller body is folded as described above, However, the hood stay in the hood 30 is in the way, and the push bar 15 cannot be sufficiently contracted, and the height of the folded stroller cannot necessarily be reduced.

  That is, as shown in FIG. 16, the hood 30 has two inverted U-shaped hood stays 30a and 30b whose base ends are pivotally mounted on the same axis with respect to the hood angle 31, and the hood stay 30a, A hood cloth is stretched between 30b. Thus, the hood 30 is mounted on the stroller body by inserting the column-shaped support rod 31a of the hood angle 31 into the cylindrical portion 32a of the hood mounting member 32 fixed to the support pipe 17 so as to be rotatable. be able to. In the above hood, the height of the front hood stay 30a is made higher than that of the rear hood stay 30b in order to make the living space as large as possible. Therefore, when the stroller is folded, the front and rear hood stays 30a and 30b are substantially parallel to the support pipe 17, and the top end of the front hood stay 30a projects upward from the rear hood stay 30b. When the stroller body is folded, the front hood stay 30a in the hood 30 becomes an obstacle, and the push bar 15 cannot be sufficiently contracted, and the folded stroller in the height direction of the stroller Dimensions cannot always be reduced.

  In view of the above, an object of the present invention is to obtain a stroller top that can reduce the height dimension of the stroller when folded during storage or carrying.

The invention relates to a stroller hood that can be folded when stored or carried, wherein a plurality of hood stays bent in an inverted U shape for supporting the hood cloth and a base end portion of the hood stay are pivotally attached. A hood angle that can be attached to and detached from the hood mounting member fixed to the straight tube portion of the handrail of the stroller or the support pipe, and the height of the front hood stay among the plurality of hood stays is set to the height of the rear hood stay. The center hood stay is located between the front hood stay and the rear hood stay so that the pivot shaft with respect to the hood angle of the front hood stay is located below the pivot shaft with respect to the hood angle of the rear hood stay. The front hood stay and the intermediate hood stay are pivotally mounted on the same axis, the rear hood stay is fixed to the hood angle, and the hood plate to which the front hood stay is fixed is rotated. Possible The front hood stay and the intermediate hood are provided with locking irregularities for engaging the opposed surfaces of the hood plate and the hood angle with each other and fixing the front hood stay in the folded or unfolded position. A stroller hood characterized in that a bendable clasp is provided between the stay and the front hood stay and the intermediate hood stay to approach or separate from each other.

  As described above, in the present invention, the mounting shaft for the hood angle of the front hood stay is provided below the mounting shaft for the hood angle of the rear hood stay. Despite the size being larger than the rear hood stay, the front hood stay height can be lowered compared to the conventional one when folded, and the hood stay becomes an obstacle to the shrinkage of the handrail. Without this, the height dimension of the stroller can be reduced.

  As described above, the present invention makes the height of the front hood stay larger than that of the rear hood stay, and the attachment shaft for the hood angle of the front hood stay is the attachment shaft for the hood angle of the rear hood stay. Even though the height of the front hood stay is larger than that of the rear hood stay, the height of the front hood stay can be made relatively low when folded. The hood stay does not interfere with the shrinkage of the baby stroller, and the height of the stroller can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a side view showing a schematic configuration of a stroller equipped with a hood 40 according to the present invention, in which a straight pipe portion 41 of a handrail of the stroller is extendable. That is, FIG. 2 is a longitudinal sectional view of the straight pipe portion 41 of the hand barb, and FIG. 3 is an enlarged partial view thereof. The straight pipe portion 41 of the hand barb includes a small-diameter lower pipe 42 having a lower end attached to the stroller body, a small-diameter upper pipe 43, and a large-diameter joint pipe that connects the lower pipe 42 and the upper pipe 43. The lower part of the large-diameter joint pipe 44 is fitted to the top end portion of the small-diameter lower pipe 42 via the bush 45, and the joint pipe 44 is fixed to the lower pipe 42 by the pin 46. Yes. The small diameter upper pipe 43 is inserted into the upper portion of the large diameter joint pipe 44 so as to be slidable in the axial direction in a nested manner, and the straight pipe portion 41 of the hand barge can be expanded and contracted by the movement of the upper pipe 43. is there.

An adjustment holder 47 is movably provided along the upper pipe 43 in the small-diameter upper pipe 43, and a lock pin holding portion 47 a is provided below the adjustment holder 47. The above lock pin holding portion 47a is formed with parallel opposing surfaces to each other, the cam grooves 47a ₁ extending obliquely upward is provided on a surface of the opposing, groups of the lock pin 48 to be described later to the cam grooves 47a ₁ The left and right cam portions formed at the ends are engaged. That is, as shown in FIG. 3, a lock pin guide 49 is attached to the small diameter upper pipe 43, and the lock pin 48 can move in the radial direction relative to the upper pipe 43. to have been fitted, the cam portions of the left and right that are formed on the proximal end of the lock pin 48 is engaged ₁ engaging the cam groove 47a.

  On the other hand, the large-diameter joint pipe 44 includes the lock pin 48 when the push bar with the upper pipe 43 in the maximum pulling position is extended and when the push bar with the upper pipe 43 inserted into the joint pipe 44 is contracted. Fitting holes 50 and 51 for selectively engaging the lock pin 48 are provided at positions corresponding to. A joint pipe cap 52 that covers the fitting hole 50 is fixed to the top end portion of the large-diameter joint pipe 44, and the fitting hole 51 is covered at a position corresponding to the fitting hole 51. A hole cover 53 is provided.

  The upper pipe 43 is coaxially fitted with a grip end 54 at the upper position, and a pin 56 is inserted into an elongated hole 55 formed in the grip end 54 and the upper pipe 43 in the axial direction. The top of the adjustment holder 47 is connected to the pin 56. An adjustment spring 58 that biases the adjustment holder 47 downward is interposed between a spring receiver 57 provided on the upper pipe 43 and an adjustment holder 47. Further, a cylindrical adjustment operation member 59 is fitted to the grip end 54, and the adjustment operation member 59 is connected to the pin 56.

Thus, when stored or carried, after being folded or folded in the same manner as a conventional stroller, the adjustment operation member 59 is lifted from the position shown in FIG. 2 to the position shown in FIG. 3 against the adjustment spring 57. If, adjusting holder 47 is moved upward, the lock pin 48 is retracted into the upper pipe 43 by the engagement of the cam grooves 47a ₁ of the adjustment holder 47, engaged with the fitting hole 50 of the large diameter of the joint pipe 44 The combination is released (see FIG. 4A). Therefore, when the upper pipe 43 is completely inserted into the joint pipe 44 and is released from the adjustment operation member 50, the adjustment holder 47 is lowered with respect to the upper pipe 43 by the adjustment spring 57, as shown in FIG. As shown, the lock pin 48 protrudes in the radial direction, and the lock pin 48 engages with the lower fitting hole 51. Therefore, the straight tube portion 41 of the hand barb is changed from the state of FIG. 2 to the contracted state shown in FIG. 4B, and the height of the stroller can be lowered by the L dimension of FIGS. It can be made compact for convenient portability. FIG. 5 shows a state in which the stroller is folded in a tri-fold state on the right half side, and further shows a state in which the hand barb is further contracted from the position indicated by the dotted line to the position indicated by the solid line on the left half side and the height thereof is lowered. .

  On the other hand, when a stroller is used, when the upper pipe 43 is moved upward after the lock pin 48 is removed from the fitting hole 51 by operating the adjustment operating member 59 upward, The provided lock pin guide 49 abuts on the first inner bush 60 fixed to the top end opening of the joint pipe 44. Therefore, when the hand is released from the adjustment operation member 59, the lock pin 48 is engaged with the upper fitting hole 50, the upper pipe 43 is fixed to the joint pipe 44, and the normal use state in which the push bar is extended. Can be.

  As shown in FIG. 1, a hood mounting member is fixed to a support pipe (not shown) to which the armrest 16 is pivotally attached, as in the conventional stroller shown in FIG. A hood 40 is attached to the mounting member.

  In other words, the hood 40 has an inverted U-shaped front hood stay 66a, an intermediate hood stay 66b, and a rear hood stay 66c whose base ends are attached to the hood angle 65, and the front hood stay 66a, A hood cloth 67 is stretched between the intermediate hood stay 66b and the rear hood stay 66c. The front hood stay 66a and the intermediate hood stay 66b are connected by a bendable / expandable clasp 68, and the front hood stay 66a and the intermediate hood stay 66b are swung in the approaching direction. It can be held in a folded state or in a state of being swung in a separating direction and expanded in a V shape in a side view.

  FIG. 6 is an enlarged view showing the structure of the mounting portion of the hood angle 65 and the hood stays 66a, 66b, 66c. The hood angle 65 is provided with a columnar support rod 65a extending downward at the rear thereof. The support rod 65a is inserted and attached to the cylindrical portion of the hood mounting member fixed to the support pipe so as to be rotatable about the axis. The base end portion of the rear hood stay 66c is pivotally attached to the hood angle 65 at a position above the support rod 65a by a shaft 69, and front and rear ribs 70a, 70b provided on the surface of the hood angle 65 are provided. Thus, the rear hood stay 66c cannot be swung with respect to the hood angle 65. A hood plate 71 is rotatably mounted on the hood angle 65 by a shaft 72 below the mounting shaft 69 of the rear hood stay 66c and in front of the support rod 65a. The base end of the bottom hood stay 66a is integrally mounted, and the base end of the intermediate hood stay 66b is pivotally attached to the shaft 72.

  A locking projection 73 is formed on the surface of the hood angle 65 facing the hood plate 71, while the front hood stay 66a is in the folded or unfolded position on the surface of the hood plate 71 facing the hood angle 65. At some point, recesses 74a and 74b that are elastically engaged with the locking projection 73 and plastic are formed so that the front hood stay is positioned.

  FIG. 8 is a diagram showing the operating state of the hood. When the hood is not used, as shown in FIG. 8A, the intermediate hood stay 66b is tilted along the rear hood stay 66c and the clasp 68 is moved. By bending the front hood stay 66a, the front hood stay 66a can also be swung rearward so that the three hood stays can be brought close to each other and folded. Further, from the position shown in (a) above, as shown in (b), only the front hood stay 66a is swung forward, and the stopper 67 is made straight, so that the hood is in a semi-deployed state. Further, by swinging the hood stays 66a and 66b forward, the hood can be fully developed as shown in FIG.

  By the way, as described above, in the stroller hood, in order to make the living space as wide as possible when using the hood, the height of the front hood stay should be higher than that of the rear hood stay. Therefore, when the hood is folded as shown in FIG. 1 and FIG. 8 (a), the height of the hood stay becomes high, and the hand hoe is used when the push heel is contracted when the stroller is folded. There is a problem in that the hand barb cannot be sufficiently contracted by contacting the folded hood stay. However, in the above embodiment, the base end portions of the front hood stay 66a and the intermediate hood stay 66b are pivotally attached to a position below the base end mounting position of the rear hood stay 66c. The height of the hood stay 66a and the intermediate hood stay 66b can be reduced, and the hand barb can be sufficiently contracted.

  In the above embodiment, an example of a large hood using three hood stays has been shown. However, as shown in FIGS. 9A and 9B, two hood stays of a front hood stay 66a and a rear hood stay 66c are provided. It can also be applied to the small hood used. Further, in this case, the intermediate hood stay 65b is removed, and the front hood stay 66a and the rear hood stay 66c are connected to each other by a clasp 68, so that parts other than the intermediate hood stay 65b are shared between the large hood and the small hood. be able to. In the above embodiment, the hood is attached to the support pipe. However, it goes without saying that the hood may be attached to the straight pipe portion of the hand barb.
