Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "first", "second" and "third" do not denote any order, but rather are used to distinguish one name from another.
Referring to fig. 1, the multifunctional folding table includes two side legs 1, 2, each of which is a scissor-type cross leg. A parallelogram mechanism is connected between the foot rests on the two sides. The parallelogram mechanism is composed of four parallel rods 3, 4, 5 and 6 and a plurality of horizontal plates 7 which are used for splicing the table top. Wherein, the two parallel rods 3 and 4 are hinged with the foot rest 1 at the same side through a hinge shaft 8. The other two parallel rods 5 and 6 are hinged with the foot rest 2 on the other side through a hinged shaft. Two opposite side edges of each horizontal plate 7 are respectively hinged with the parallel rods 3 and 4 on the same side and the parallel rods 5 and 6 on the same side. More specifically, each horizontal plate 7 is hinged to said parallel bars by means of a bracket 9. The horizontal plate 7 is fixed with the bracket 9, and the horizontal plate 7 is fixed on the bracket 9 with the articulated shafts articulated with the four parallel rods 3, 4, 5 and 6. The whole parallelogram mechanism can rotate on the vertical surface around the articulated shafts 8 between the four parallel rods and the foot rests on the two sides.
Referring to fig. 2, when the parallelogram mechanism is rotated to an angle where the four parallel bars 3, 4, 5, 6 are parallel to the horizontal plane, all the horizontal plates 7 are at the same height, and the whole folding table becomes one table. The parallel bars 5, 6 are hidden from view in fig. 2.
Referring to fig. 4, when the parallelogram mechanism rotates to the angle that the four parallel rods 3, 4, 5, 6 are perpendicular to the horizontal plane, different horizontal plates 7 are located at different heights, the whole folding table becomes a shelf, and the horizontal plates 7 become the layers of the shelf.
The articulated shaft that every side foot rest and two parallel bars of homonymy articulated is fixed on a rotor, and the rotor rotates with the foot rest and is connected. Specifically, the articulated shaft 8 of the parallel rods 3 and 4 articulated with the foot rest 1 is fixed on a rotating body 14a, and the rotating body 14a is rotationally connected with the foot rest 1. The articulated shaft 8 of the parallel rods 5 and 6 and the foot rest 2 is fixed on the other rotating body 14b, and the rotating body 14b is rotationally connected with the foot rest 2 on the other side.
In order to make the description clearer and more concise and avoid encumbrance, only the connection structure between the foot rest 1 and the rotating body 14a connected with the foot rest is explained in more detail below. The connection structure between the foot rest 2 and the other rotating body 14b connected with the foot rest is the same as the connection structure, and the description is omitted.
Referring to fig. 1, 6 and 7, the rotating body 14a is provided with a clamping groove 17, and a pin 18 corresponding to the clamping groove 17 is fixed on the foot rest 1 rotatably connected with the rotating body 14 a. When the rotor 14a rotates upward around the rotation axis 15 between the rotor and the stand 1, the pin 18 can be withdrawn from the catch 17 as shown in fig. 7. After the pin 18 is withdrawn from the engaging groove 17, the rotating body 14a can freely rotate around the rotating shaft 15. Conversely, when rotor 14a rotates downward about shaft 15, pins 18 may enter pockets 17 as shown in fig. 8.
Referring to fig. 6 to 8, a first hook 16 is hinged to the rotating body 14 a. When the pin 18 enters the slot 17, as shown in fig. 9, 1, 2 or 4, the first hook 16 can hook onto the pin 18, thereby locking the pin 18 in the slot 17. When the pin 18 is locked by the first hook 16, the rotating body 14a is locked by the pin and cannot rotate, and the rotating body 14a is fixed with the foot rest 1 into a whole.
As a preferred embodiment, as shown in fig. 7 and 8, the locking groove 17 is a "T" shaped locking groove, and the pin 18 inserted into the locking groove 17 is locked in the branch 17' of the "T" shape by the first hook 16 of the rotating body 14 a. This structure is more robust.
Referring to fig. 1, one of the two parallel rods 3 and 4 on the same side of the foot rest 1 is hinged with a second hook 10, and the other parallel rod 4 is fixed with a pin 11. When the vertical distance between the two parallel bars 3, 4 is minimized with the deformation of the parallelogram mechanism, as shown in fig. 2, 3, the second hook 10 may be hooked on the pin 11 so that the vertical distance between the two parallel bars 3, 4 is locked by the second hook 10 and cannot be changed. When the two parallel bars 3, 4 are locked by the second hook 10, the whole folding table is locked in the table configuration if the rotor 14a is also locked against rotation by the first hook 16 and the pin 18. It should be noted that in this embodiment, not only the second hook 10 is provided between the two parallel bars 3 and 4, but also a hook having the same structure and function is provided between the two parallel bars 5 and 6 on the other side.
Referring to fig. 1, the foot rest 1 is hinged with a third hook 12, and a pin 13 is fixed on one parallel rod 4 on the same side of the foot rest 1. When the third hook 12 is hooked on the pin 13 as shown in fig. 4 and 5, the relative position of the parallel rod 4 and the foot rest 1 is locked by the third hook 12 and cannot be changed. At this time, if the rotating body 14a is locked by the first hook 16 and the pin 18 and cannot rotate, the whole folding table is locked in the shape of the shelf.
It should be noted that the mounting mode of the third hook 12 can be turned, that is, the third hook 12 is hinged on the parallel rod 4, and the pin 13 is fixed on the foot rest 1.
It should be noted that a hook and a pin having the same structure and function as the third hook 12 and the pin 13 are also provided between the other side foot rest 2 and the one parallel rod 6 on the same side in the present embodiment.
The following illustrates the steps of changing the shelf to a table and the table to a collapsed configuration shown in fig. 4. Starting from fig. 4, the third hook 12 is rotated to separate the third hook 12 from the pin 13, then the entire parallelogram mechanism is rotated to the configuration shown in fig. 2, and then the second hook 10 is rotated to hook the second hook 10 on the pin 11, so that the entire parallelogram mechanism is locked from rotation. So far, the conversion from the commodity shelf to the desk is completed. Starting from fig. 2, the first hook 16 is rotated to separate the first hook 16 from the pin 18, and then the rotating bodies 14a and 14b are rotated around the rotating shaft 15 together with the whole parallelogram mechanism, and the two side legs 1 and 2 are folded at the same time, and the scissors-type cross legs are folded together, so that the folding operation is completed, and the whole table is changed into the folded state shown in fig. 10. All operations do not need to disassemble and assemble screws, and the operation is simple and convenient.
It should be noted that, the hinge shafts of all the hinge parts and the rotating shafts of the rotating connection parts of the present invention may be, but not limited to, rivets, screws, and bolts.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
