Description

  The present invention relates to a foldable suitcase that can be opened and closed, and in particular, a pair of pullbacks of the suitcase can be interlocked to open and fold and secure the case body to provide convenience for use and storage by the user. About.

  When carrying a large amount of luggage for long trips, use a suitcase to store it. However, contractors have developed foldable suitcases because they can take up space when not using suitcases.

  Unfortunately, the current collapsible suitcase has the following disadvantages.

1) After folding the suitcase, it may be opened when moving if it is not fixed by tying it with a rope or belt anew, which is inconvenient for the user's use.

2. When the suitcase is opened, since it does not have a function to fix it stably, it is necessary to attach, support and place reinforcements etc. on the inside of the suitcase, which is also inconvenient for use.

  The main object of the present invention is to use a pressing device attached to the base to push in a pull which is pivotally connected to the base, and when the pull is pivoted in a direction to pull the base apart, Depending on the amount of pushing force, it is automatically pivoted to fix in the upright state, and there is no need for fixing or reinforcement by other fixing means, and the case body connected between the base part and the puller is automatically opened and fixed It can be folded, closed and fixed, providing convenience for the user.

  In order to achieve the above object, the automatic self-opening and closing foldable suitcase includes a base portion, a pull hand set and a foldable case body. The pull handle has a fixing bar, one end of the fixing bar is pivotally connected to the side surface of the base, the first pressing face is formed at the end of the fixing bar, and the fixing bar is formed on the surface near the base (2) A pressing surface is formed, the case body is connected to the base portion, and one side of the case body is connected to the fixing bar. Furthermore, the pusher device is installed in the base portion, and the pusher device has the elastic tool and the pusher whose surface forms a flat surface, and the pusher is positioned below the pivoting place with the fixing bar of the puller set. The elastic tool is located between the pusher and the base, and pushes the pusher against the fixing bar. When the case body is folded to the base portion, the case body interlocks and pivots so as to bring the fixing bar closer to the base portion, and is pressed against the second pressing surface of the fixing bar by the pressing force of the pusher. The bar automatically pivots to form a lock. On the other hand, when the case body is opened at the base portion, the case body interlocks the fixing bar and pivots in the direction to separate the base portion, and presses against the first pressing surface of the fixing bar by the pressing force of the pusher. And the fixing bar pivots automatically to form a fixing.

  Among them, the accommodation groove 11 is provided on the surface on one side of the base portion 1, the base portion 1 is provided with the guide groove 111 on the side wall on both sides of the accommodation groove 11, and the surface of the base portion 1 is pivoted on both sides of the accommodation groove 11 A pivot 12 is provided on the pivot 12 and the lower side of the base 1 is connected to the roller 14.

  The puller set 2 has a fixing bar 21, an extending rod 22 provided in order through the fixing bar 21 and a handle rod 24, and the extending rod 22 and the handle rod 24 are fixed to the fixing bar 21. It can be stretched and closed along. The hook 23 is fitted to the extension rod 22, the hook 23 has a fitting portion 231, the side surface of the fitting portion 231 is bent to form the hook portion 232, and the fixing hole 233 is provided in the fitting portion 231. Thus, the fitting joint portion 231 is fitted to the outside of the extension rod 22, and the side surface of the extension rod 22 is provided with the fixing pillar 221 which can be drawn elastically, and the fixing pillar 221 is provided in the fixing hole 233. Furthermore, one end of the fixing bar 21 is pivotally connected to the pivot 13 of the side surface of the base 1 to form a first pressing surface 211 at the end of the fixing bar 21, and the fixing bar 21 presses the surface near the base 1 A contact surface 212 is formed, and the fixing bar 21 provides an arc-shaped guide surface 213 between the first contact surface 211 and the second contact surface 212.

  The case body 3 has a base portion 31. A back portion 32 is formed on one side of the base portion 31. The back portion 32 extends upward the fold portion 33, and the fold portion 33 is provided with a lug 34. A side wall 35 is extended to the back 32 and the bottom of the fold 33, and a front lid 36 is further extended to the other side separating the base 31 and the back 32. A fastener 37 is provided between the side wall portion 35 and the side wall portion 35. Further, the base portion 31 is connected to the surface of the base portion 1, and the back portion 32 is connected to the fixing bar 21 of the pull set 2.
