Description

The present invention relates to a structure of a foldable snack bar car, and more particularly to a foldable snack bar car structure in which a multi-layer panel storage space is formed on a frame.

A conventional folding snack bar car has only upper and lower panel sets, and a large space is not used between the upper and lower panel sets of such folding snack bar cars. Since the structure such as a basket is added to increase the use space, but the snack car has a folding action, the basket can be folded by being designed in the half space of the frame, and therefore There is a lack of available space.

    The present inventor proposes the present invention in which the above-mentioned drawbacks are studied carefully, and the above-mentioned disadvantages can be effectively eliminated by utilizing the theory, and the design is rational.

A main object of the present invention is to provide a structure of a folding snack bar car in which a multi-layer panel storage space is formed on a frame.

The invention of claim 1 mainly includes two substantially U-shaped outer frames, two substantially U-shaped inner frames assembled in the two outer frames, and two bottom frames. A frame provided with two casters, an engagement member provided at the upper ends of the two inner frames, two connecting rods pivotally attached to the upright bars of the two inner frames, and upper ends of the two outer frames An upper panel set pivotally mounted between the two engaging members, and a lower panel pivotally mounted near the bottom ends of the two outer frames by two connecting rods and pivotally mounted on the inner frame by bolts. And a set of foldable snack bar vehicles.

In the invention of claim 2, the two substantially U-shaped outer frames of the frame are bent at a right angle, and a caster seat is provided at the bottom end near the curved position to fix the caster. The structure of the foldable snack bar car according to claim 1.

The folding snack bar according to claim 1, wherein a bar frame is provided around the two panels of the intermediate panel set except for opposing sides. This is the structure.

    Hereinafter, the features and technical contents of the present invention will be described in detail with reference to the drawings. However, the drawings and the like are for reference and explanation, and the present invention is not limited thereby.

Referring to FIGS. 1 and 2, the present invention includes two substantially U-shaped outer frames 11, 12 and two outer frames 11, 12 assembled into a substantially U-shaped inner frame 13, and two outer frames. A frame 10 provided with two casters 20 at the bottom ends of the frames 11 and 12, respectively, an engagement member 30 provided at the upper ends of the two inner frames 13, and an upright bar 130 of the two sets of inner frames 13. Two connecting rods 41 and 42 pivotally mounted on the upper sleeve 40 pivoted to the upper sleeve 40 and an upper panel set pivoted between the upper ends of the two outer frames 11 and 12 and the two engaging members 30 50 and a lower panel set 60 which is pivotally mounted near the bottom ends of the two outer frames 11 and 12 by two coupling rods 41 and 42 and pivotally mounted on the inner frame 13 by bolts 80, Upper and lower panel set 50, 6 In between, at least one intermediate panel set 70 is provided, and the intermediate panel set 70 comprises two panels 71 and 72 assembled in opposition to each other. Protruding pivot seats 710 and 720 that are locked to the 13 upright rods 130 are provided, and the outer ends of the other two panels 71 and 72 are pivotally attached to the two outer frames 11 and 12. On the frame 10, a multi-layered panel storage space is formed.

Hereinafter, structural features, technical means, and expected effects according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 3, when the folding snack bar car according to the present invention is used, the panel sets 50, 60, 70 of each layer are spread on the frame 10 in a flat shape, and at this time, for pivotal attachment. The outer frames 11 and 12 and the inner frame 13 are expanded at a maximum interval, and the inner frame 13 is located at the same height and in the middle of the two outer frames 11 and 12. The sleeves 40 of the two connecting rods 41 and 42 pivotally mounted on the two upright rods 130 are located at the upper ends of the two upright rods 130 and engage with the engaging members 30 at the upper ends thereof. The lower portions of the two connecting rods 41 and 42 pivoted on the upper side are opened and pivoted on the outer sides of the two panels 61 and 62 of the lower panel set 60, and the inner sides of the two panels 61 and 62 of the lower panel set 60. In the folding position, A pivoting seat pivotally coupled with the boom 13 and bolts is formed, and the upper panel set 50 comprising two panels 51 and 52 is engaged with the opposing adjacent sides at the upper end of the inner frame 13, respectively. Two pivoting seats 510 and 520 pivotally attached to the member 30 are provided, and the outer sides of the two panels 51 and 52 are pivotally attached to the outer frames 11 and 12 by four bolts 80. The pivoting sheets 710 and 720 on the sides where the two panels 71 and 72 of the intermediate panel set 70 are joined to each other are pivotally coupled to the upright rod 130 of the inner frame 13 by the two bolts 80. The outer ends of 71 and 72 are pivotally attached to the two outer frames 11 and 12 by four bolts 80, thereby releasing the engaging member 30 engaged on the sleeve 40 when the present invention is folded. Al, Pulling upwards, each panel set 50, 60 which pivotally attached on the inner frame 13 and the two outer frames 11 and 12 are folded to the inner being linked to synchronization (as shown in FIG. 4).

Further, the two substantially U-shaped outer frames 11 and 12 of the frame are bent at a right angle, and caster seats 110 and 120 for fixing the caster 20 are provided at the bottom ends of the curved positions. Thereby, since the caster 20 can approach the outer side of the flame | frame 10 more, the stability of a folding snack bar car is improved.

Referring to FIG. 5, according to another embodiment of the present invention, the bar frame 711, around the two panels 71, 72 of the intermediate panel set 70, except for the oppositely adjacent sides. 721 is provided so that the stored item does not easily fall.

    As described above, according to the structure of the foldable snack bar car according to the present invention, it is possible to effectively eliminate the disadvantage that the storage space for the snack bar car is insufficient.

Therefore, the present invention is more progressive and more practical, and filed a utility model registration request in accordance with the law.

The above is only a better embodiment of the present invention, and the present invention is not limited thereby, and equivalent changes made based on the scope of claims for patent registration relating to the present invention and the contents of the description. All modifications and changes are included in the scope of the claim for registration of the present invention.
