Description

Vehicle with cross-section function

The present invention relates to a form that can be arbitrarily converted into a cart or a cart, and is constructed by a vehicle with a step.

Due to the increasing workload and scope of work of today's housekeepers, the tools used by the housekeepers have not improved as the workload has increased. The main equipment of the house clerk is the trolley and the slab. When used in different terrains or goods, the trolley or the pallet is used to carry the cargo, but the loading space and weight of the occupant are increased. Moreover, once a platform with a step is encountered, no matter whether it is a trolley or a pallet, it is useless, and the goods must be carried by humans to cross the section, which is quite labor intensive.

Therefore, there is a new patent No. M525308 "Foldable Ladder Pulling Car" announced by the Republic of China on July 11, 105, which discloses: a tie rod unit having a back frame at its bottom end; a bracket, its pivot Attached to the front of the back frame can be flipped up or down to expand; two sets of transmission units arranged on the two sides of the back frame, each transmission unit has an active member interlocked with the bracket, and a passive member driven by the active member; And two sets of ladder wheel units, each of which has a bracket connected to the passive member, a wheel frame rotatably coupled to the bracket, and three rollers coupled around the wheel frame; thereby allowing the user to manually flip The bracket is folded or unfolded. When the bracket is turned over, the two sets of ladder wheel units are folded by the transmission unit behind the back frame or spread on the two sides, so that the user can quickly fold or unfold, and the operation is convenient and simple. purpose.

There is also a new patent No. M554071, entitled "Foldable Ladder Pulling Car" announced by the Republic of China on January 11, 107, which discloses: a tie rod unit having a telescopic portion and a connection a connecting portion of the telescopic portion; a fixing unit having a fixing end connecting the connecting portion, a chassis end opposite to the fixing end, and a side protruding from a side of the fixing portion And a support portion connected to the end of the chassis, and a bottom pivotal end between the fixed portion and the support portion; a bottom plate unit having a bottom plate pivoting end pivotally connected to the pivotal end of the chassis, and a Conversely, the hook end of the pivotal end of the bottom plate; the two multi-wheel units are respectively pivotally connected to the two sides of the chassis unit; thereby achieving the effects of increasing the service life, saving space and improving safety.

However, although the above two patents have the function of climbing the ladder and folding and reducing the volume, they all must have three rollers to go up and down the ladder, so the components are more and more complicated. Moreover, the two patents have only a single function of the trolley, and cannot be used as a trolley, so it is also not ideal in use.

When the carriage is pushed forward to encounter a step (B) having a step difference, the step (B) is formed by interconnecting a vertical plane (B1) and a horizontal plane (B2). First, the first flying wheel (34) of the two auxiliary wheel sets (3) is pushed forward to the vertical surface (B1) (as shown in the seventh figure), and the vertical surface (B1) is applied. The two first floating wheels (34) have a reaction force for compressing the two elastic members (33), and the two first floating wheels (34) can be relatively raised. The two first flying wheels (34) are still continuously pushed up along the vertical plane (B1) (as shown in the eighth figure). Until the two first floating wheels (34) pass the vertical plane (B1), start to roll onto the horizontal plane (B2) (as shown in the ninth figure), and the second second floating wheels (35) will start It touches the vertical plane (B1) and continues to roll up along the vertical plane (B1). Finally, when the two first flying wheels (34) and the two second flying wheels (35) are both rolled onto the horizontal plane (B2) (as shown in the tenth figure), the passage can be quickly and smoothly passed. The ladder (B) can be used to transport the cargo (A).

When it is required to be used as a trolley, as shown in the second figure and the eleventh figure, the first sliding portion (22) and the second sliding portion (23) of the carrier plate (2) are opposite to each other. The end of the first end (12) is close to sliding, and the carrier plate (2) is pivotally bent into a vertical shape corresponding to the two sliding frames (21), thereby expanding the use of the carrier plate (2). And the two sleeves (52) of the handle frame (5) are stretched and used relative to the rotating base (51), and at the same time, the handle frame (5) is pressed inwardly, so that the two clamping blocks (511) respectively The horizontal corresponding card is inserted into the two horizontal card slot (412) (as shown in FIG. 15). The two locking devices (53) are used to lock the holding rod (54). In this way, it can be used as a hand to push a cargo (A1).

When the stepper (B) having the step difference is pushed forward by the pusher, the first dangling wheel (34) and the second dangling wheel (35) of the two auxiliary wheel sets (3) are successively actuated. It is exactly the opposite of the operation of the aforementioned cart, so please refer to the seventh to tenth drawings, and no further drawing is shown. Firstly, the second flying wheel (35) of the two auxiliary wheel sets (3) is forwardly contacted to the vertical surface (B1) (please refer to the seventh figure), and the vertical surface (B1) is used to apply the two The second flying wheel (35) has a reaction force for stretching the two elastic members (33), and the second flying wheels (35) can be relatively raised. The second second idler wheel (35) is still pushed continuously to roll up along the vertical plane (B1) (please refer to the eighth figure). Until the two second floating wheels (35) pass the vertical plane (B1), start to roll onto the horizontal plane (B2) (please refer to the figure IX), and the two first flying wheels (34) Begin to touch the vertical plane (B1) and continue to roll up along the vertical plane (B1). Finally, when the second second floating wheel (35) and the two first floating wheels (34) are rolled to On the horizontal plane (B2) (please refer to the tenth figure), the step (B) having a step can be quickly and smoothly passed, and the cargo (A1) can be transported with low effort.
