ている。（例えば、特開平６−３７０５０号公報参照）An operating mechanism for folding / assembling is a drive pulley for an operation wire rotatably mounted in a housing, and the drive pulley is vertically slidably mounted on a lower portion of the housing. It is constituted so that it may rotate. Thus, when the operation lever is gripped and moved upward, the drive pulley is rotated, and accordingly, the left and right operation wires are respectively moved in opposite directions, and the vehicle body frame is in a foldable state. In order to prevent the operation lever from unexpectedly moving when the stroller is being pushed, the housing is provided with a slide regulating stopper for preventing a malfunction of the operation lever (an erroneous sliding of the operation lever). Is provided. (See, for example, JP-A-6-37050)

できにくいという不便さを有する。However, the slide restricting stopper for preventing the operation lever from erroneously operating is capable of sliding on the upper surface of the housing in the lateral direction (the left-right direction along the longitudinal direction of the housing). It is mounted freely, and the operation of the operation lever is regulated by the lateral sliding of the slide regulating stopper. However, in the left-right sliding type, even if the sliding lever is used to hold the housing, the sliding restricting stopper restricts the operation of the operating lever, or the operating lever. It is not possible to determine which position is the unlocked position that allows the operation of, and therefore, the contents of the display sticker affixed to the surface of the housing provided with the slide restriction stopper are checked and confirmed. Is the actual situation. That is, there is an inconvenience that it is difficult to determine the position of the slide regulating stopper by the tactile sensation of the hand holding the housing.

ことになる。Also, the above-mentioned stopper for sliding control may move in the left-right direction while pushing the stroller while holding the housing of the push rod. Therefore, the stopper for sliding control may be moved while pressing the stroller. There is a danger of moving in the left-right direction and switching from the locked state to the unlocked state without knowing. If the stopper for sliding control is moved from the locked position to the unlocked position without your knowledge, the operating lever will be operated with the hand holding the housing, and as a result, the stroller will be disassembled and run. Of course, there is a danger to infants riding.

In a stroller provided with a lock member for preventing the lock member, the lock member is slidably mounted in a direction intersecting the longitudinal direction of the connecting member, and the lock member has an outer shape of the connecting member in a locked state for preventing the operation element from being immersed. When the lock is released to allow the operation element to be immersed, a part of the lock member is projected outside the outer shape of the connecting member. And effect.

態などが挙げられる。The body frame constituting the stroller includes a pair of left and right front leg rods, a rear leg rod, an armrest rod, a hand pushing rod, and several connecting rods for connecting the pair of front and rear leg rods in the width direction. A pair of left and right folding reversing members and a folding link rod connecting the front leg rod, the rear leg rod, and the hand pushing rod are configured to be foldable in the front-rear direction and the width direction.
Further, the direction intersecting the longitudinal direction of the connecting member to which the lock member is attached may be a front-rear direction or a vertical direction intersecting at right angles to the longitudinal direction, or an intersecting angle other than at right angles to the longitudinal direction. On the upper surface of the device.

とは全くない。According to the above means, the lock member for restricting the operation of the operation member is slidably provided in a direction intersecting the longitudinal direction of the connecting member (front-back direction, up-down direction, etc.)
Moreover, the lock member is located within the outer shape of the connecting member in the lock position for preventing the operation member from being immersed, and a part of the lock member is in the outer shape of the connection member in the unlocked position where the operation member can be operated (immersed). Since it protrudes further outward, the position (state) of the lock member can be reliably determined by the feel of the hand gripping the connecting member of the push rod. In other words, when the lock is released, a part of the lock member protrudes outside the outer shape of the connecting member. Of course, it is possible to distinguish at a glance visually without looking at the display seal. Further, even when the stroller is in the assembled position of the stroller with the lock member in the locked position, even if the lock member is held in the outer shape of the connection member, the lock member holds the connection member. There is absolutely no chance of being moved with your hands without your knowledge.

することができる。According to the folding and assembling operation mechanism of the folding stroller of the present invention, the position (state) of the lock member can be changed by the touch of the hand gripping the connecting member of the push rod by the structure of the first and second aspects. Judgment can be made reliably. That is, when the operator unlocks the lock member, a part of the lock member protrudes outside the outer shape of the connecting member. Of course, it is possible to distinguish at a glance visually without looking at the display seal. or,
In the assembled state of the stroller in the lock position where the lock member restricts the operation of the operation element, even if the stroller is grasping the connecting member of the push rod, the locking member is housed within the outer shape of the connecting member. Will not be moved to the unlocked position without your knowledge by the hand holding the connecting member. Therefore, it is possible to provide a stroller that eliminates the drawbacks of the conventional device that slides along the longitudinal direction (left-right direction) of the grip portion and that can be used with confidence.
