Description

Technical Field

[0001] The utility model relates to a handling carrier, in particular to a trolley. Background Art

[0002] Generally, a known trolley generally includes a frame, wheels mounted at the bottom of the frame, and a bottom shovel plate body disposed at the bottom of the frame and having a horizontal sheet-like structure. The trolley is used by shoveling up an article placed on the ground with the bottom shovel plate body, then making the carried article lean back against the frame, and finally transporting the article through the wheels.

[0003] The problem in using the trolley is that either the article cannot be smoothly shoveled up with the bottom shovel plate or the article cannot be stably leaned back against the frame. When the above situation occurs, the user mostly uses his hands to assist in stabilizing the article. However, when the user uses the trolley in the way of using his hands to assist in stabilizing the article, there is a considerable danger. When the article has a sharp structure on its surface, the user's hand will be stabbed by the article. When the article is too heavy, it is not only unfavorable for the overall force application but also likely to cause injury due to improper force application for the user to assist in stabilizing the article with his hands. Therefore, using both hands to control and stabilize the frame is the most ergonomic and safest way of use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a trolley that can overcome at least one shortcoming of the background art.

[0005] The trolley of the utility model is suitable for transporting articles and includes: a frame mechanism, a clamping and leaning mechanism, and a stepping mechanism. The frame mechanism includes a frame unit extending vertically and capable of carrying the article, and a wheel unit mounted on the frame unit and capable of driving the frame unit to move; the clamping and leaning mechanism includes two clamping and leaning frame units that are spaced left and right and pivotally arranged at the bottom end of the frame unit so as to be able to pivot left and right, and two elastic reset members respectively connected between the clamping and leaning frame units and the frame unit. The clamping and leaning frame units can be driven to pivot towards each other left and right and approach the frame unit, and can be used to change between a clamping position where the goods carried by the frame unit are clamped left and right and an open position where the clamping and leaning frame units pivot away from each other left and right. The elastic reset members always have an elastic force that drives the clamping and leaning frame units to change towards the clamping position; the stepping mechanism is pivotally arranged at the bottom end of the frame unit so as to be able to swing back and forth, and leans forward against the clamping and leaning frame units. The stepping mechanism can be driven to pivot downwards by stepping on it, and drives the clamping and leaning frame units to change towards the open position.

[0006] For the trolley of the present utility model, each of the clamping and leaning frame units has a pivot member pivotally provided at the bottom end of the frame unit so as to be pivotable left and right, a pushing and leaning member connected to the pivot member and protruding towards another clamping and leaning frame unit, and a side clamping frame body fixed to the pivot member and protruding forward. The stepping mechanism can be stepped and pivoted to push the pushing and leaning member forward, so that the pushing and leaning member respectively drives the pivot member to pivot relative to the frame unit, and drives the side clamping frame body to swing away from each other left and right, so that the clamping and leaning frame unit changes to the open position.

[0007] For the trolley of the present utility model, the stepping mechanism includes a rotating shaft rotatably axially mounted on the frame unit left and right, a pushing member connected to the rotating shaft and abutted against the rear side of the pushing and leaning member, and a stepping member connected to the rotating shaft and located above the pushing member for stepping on.

[0008] For the trolley of the present utility model, each of the clamping and leaning frame units further has a limiting bottom plate protruding from the bottom edge of the corresponding side clamping frame body towards another side clamping frame body and capable of shoveling up and carrying the article.

[0009] For the trolley of the present utility model, the frame unit has a frame body extending vertically, and a bottom shovel plate body protruding forward from the bottom end of the frame body and capable of shoveling up and carrying the article.

[0010] For the trolley of the present utility model, the frame body has two support rods spaced left and right and extending vertically, and the clamping and leaning frame units are respectively pivotally provided at the bottom ends of the support rods.

[0011] For the trolley of the present utility model, the frame body further has a push rod straddling the top ends of the support rods, and a cross bar bridging between the support rods.

[0012] For the trolley of the present utility model, the frame body further has two bent rods spaced left and right and respectively connecting the bottom ends of the support rods. Each bent rod is connected to the corresponding support rod at its upper and lower ends and extends backward. The stepping mechanism is pivotally provided between the support rods.

[0013] For the trolley of the present utility model, each bent rod has a rear extension section extending backward from the corresponding support rod, and an obliquely upward extension section extending obliquely upward and forward from the end of the rear extension section and connected to the support rod.

[0014] The beneficial effects of the present utility model are as follows: Through the structural design of the clamping mechanism and the stepping mechanism, the user can manipulate the clamping and leaning frame unit to clamp the article by foot, so as to facilitate the frame unit to stably shovel up and carry the article, thereby avoiding the injury caused by hand assistance to stabilize the article.

[0022] Referring to Figures 1 to 3 , an embodiment of the trolley 1 of the present utility model is applicable to carrying articles. The trolley 1 includes a frame mechanism 2 for carrying the articles, a clamping mechanism 3 pivotally provided on the frame mechanism 2, and a stepping mechanism 4 pivotally provided on the frame mechanism 2 and located behind the clamping mechanism 3.

[0023] The frame mechanism 2 includes a frame unit 21 extending vertically and capable of carrying the articles, and a wheel unit 22 installed on the frame unit 21 and capable of driving the frame unit 21 to move. The wheel unit 22 has two wheels 221 respectively pivotally provided on the left and right sides of the frame unit 21 and capable of rotating forward and backward.

[0024] The frame unit 21 has a frame body 211 extending vertically, and a bottom shovel plate body 212 protruding forward from the bottom end of the frame body 211 and capable of shoveling up and carrying the articles.

[0025] The frame body 211 has two support rods 213 spaced apart from each other and extending up and down, a push-pull rod 214 detachably straddling the top ends of the support rods 213, a plurality of cross rods 215 extending from left to right and straddling between the support rods 213 and slightly convexly convexly convexly posteriorly, and two bending rods 216 spaced apart from each other and respectively connected to the bottom ends of the support rods 213. The push-pull rods 214 are used for the user to apply force to push and pull the frame body 211. The cross rods 215 are used for the objects to lean against backwards.

[0026] The top of the push-pull rod 214 is bent into a U-shaped structure with an opening facing downward, and has a push-pull cross bar 217 extending inward from the left and right sides and slightly curved and raised backward. The push-pull cross bar 217 is used for the article to lean against backward.

[0027] Each of the bending rods 216 has a rear extension section 218 extending backward from the corresponding support rod 213 , and an upward extension section 219 extending from the rear extension section 218 , bending obliquely upward and extending forward to be connected to the support rod 213 .

[0028] The clamping mechanism 3 includes two clamping frame units 31 which are spaced apart from each other and can be pivoted left and right at the bottom end of the support rod 213, and two elastic return members 32 which are respectively connected to the clamping frame units 31 and connected to the frame unit 21.

[0029] Each clamping frame unit 31 comprises a pivoting member 311 pivotally mounted at the bottom end of the corresponding support rod 213 so as to be able to swing left and right, a pushing member 312 connected to the pivoting member 311 and protruding toward the other clamping frame unit 31, a side clamping frame body 313 locked to the pivoting member 311 and extending forward in a bent manner, and two limiting bottom plates 314 mounted on the side clamping frame body 313. Each limiting bottom plate 314 protrudes from the bottom edge of the corresponding side clamping frame body 313 toward the other side clamping frame body 313, and can be used to scoop up and carry the articles. The protruding ends of the pushing member 312 are respectively connected to the elastic reset member 32.

[0030] The clamping frame unit 31 can be driven by the pedal mechanism 4 to pivot toward the frame unit 21 to the left and right, and can be used to clamp the cargo carried by the frame unit 21 to the left and right (see the clamping position). Figure 3 , 4 ), and the change between the open positions where the left and right pivots swing away from each other (see Figure 5 , 6 ).

[0031] When the clamping frame unit 31 switches from the clamping position to the open position, the pushing member 312 drives the pivot member 311 to pivot relative to the support rod 213, and drives the side clamping frame 313 to swing away from each other to the left and right, so that the clamping frame unit 31 changes to the open position.

[0032] Each of the elastic return members 32 is a spring. The elastic return members 32 always have an elastic force to drive the clamping frame units 31 to clamp toward each other.

[0033] The pedal mechanism 4 includes a rotating shaft 41 rotatably installed axially left and right between the support rods 213, a pushing member 42 connected to the rotating shaft 41 at both ends and extending obliquely downward and rearward, and a pedal member 43 connected to the rotating shaft 41 at both ends and extending obliquely upward and rearward and relatively located above the pushing member 42.

[0034] Each of the elastic return members 32 is a spring in this embodiment. However, in other embodiments of the present invention, the elastic return members 32 can also be made of elastic rubber material.

[0035] See also Figures 3 to 6 The pedal member 43 can be stepped on by the user's foot, and the rotating shaft 41 is linked to make the push member 42 pivot forward and upward (see Figure 3 and Figure 5 ).

[0036] When operating the trolley 1 to carry the article, first push the trolley 1 to the vicinity of the article, then step on the pedal 43 with your foot, the push member 42 abuts against the push member 312, drive the clamping frame unit 31 from the clamping position to the open position, and push the trolley 1 forward, so that the bottom shovel plate 212 is inserted into the bottom of the article. Then move the foot away from the pedal 43, so that the clamping frame unit 31 elastically clamps the article towards each other, and the limiting bottom plate 314 is inserted into the bottom of the article. Finally, drive the top of the frame unit 21 backward, so that the frame unit 21 is tilted with the wheel axle of the wheel 221 as the fulcrum, so that the article can be carried on the frame body 211. The bottom shovel plate 212 and the limiting bottom plate 314 will also carry the article. Through the structural design of the limiting bottom plate 314 and the clamping frame unit 31 , the limiting bottom plate 314 can be inserted into the bottom of the object and cooperate with the bottom shovel plate 212 to facilitate the frame unit 21 to scoop up the object.

[0037] Through the structural design of the elastic reset member 32 and the clamping frame unit 31, the clamping frame unit 31 can elastically clamp the article, so that the article will not be displaced left and right when being shoveled up by the bottom shovel plate body 212, thereby affecting the application of force. In addition, the elastic reset member 32 enables the clamping frame unit 31 to constantly change towards the clamping position.

[0038] In summary, for the trolley 1 of the present utility model, through the structural design of the clamping mechanism 3 and the stepping mechanism 4, a user can control the clamping frame unit 31 to clamp the article by foot, so as to facilitate the frame unit 21 to stably shovel up and carry the article, thereby avoiding the injury caused by using hands to assist in stabilizing the article, which is really safe. In addition, through the structural design of the elastic reset member 32, the clamping frame unit 31 can elastically clamp the article. Through the structural design of the limit bottom plate 314 and the clamping frame unit 31, it is beneficial for the frame unit 21 to shovel up and carry the article. Therefore, the trolley 1 of the present utility model is indeed a quite practical creation and can truly achieve the purpose of the present utility model.

[0039] The above are only specific embodiments of the present utility model, and the scope of the claims of the present utility model cannot be limited thereby. Moreover, equivalent variations made according to the recorded content of the claims and the description of the present utility model should also be covered by the scope of the claims of the present utility model.
