Description

Multiple lap assembly mat

The invention relates to a seat cushion, in particular to a seat cushion assembled by a plurality of turns.

For the existing seat cushion, please refer to FIG. 7 , which mainly includes an inflatable disc-shaped cushion body 50 . The upper surface of the cushion body 50 can protrude with a plurality of convex lobes 52 for the user to sit on. On the pad body 50, a lifting hole 54 penetrating the pad body 50 may be disposed at a near periphery of the pad body 50 to facilitate lifting or lifting the pad body 50.

However, the cushion body 50 of the existing seat cushion has an integrally formed structure, so that it can be presented only in a single color, slightly monotonous in shape, and large in overall volume, requiring a large space for transportation and storage. The need for further improvement.

Therefore, the present inventors have finally developed a present invention which can improve the existing defects in view of the problems and the defects in the existing seat cushion structure, through continuous experimentation and research.

The main object of the present invention is to provide a multi-turn assembly pad which is composed of a plurality of units, so that the appearance of different colors can be changed, and the space required for transportation and storage can be reduced. And can achieve the purpose of improving the practicality of the seat cushion.

In order to achieve the above object, the present invention provides a plurality of lap assembly pads, comprising a disk-shaped inflatable center pad body, and at least one inflatable ring body sequentially disposed around the outer surface of the center pad. An annular combined card slot and a ring-shaped combined convex portion which are mutually engageable between the center pad body and the adjacent surface of the ring body are arranged to connect the center pad body and the ring body, and the upper and lower edges of the inner surface of each combination card slot are divided An annular locking rib is not protruded, and the upper and lower edges of the outer surface of each combined convex portion are respectively recessed with an annular locking groove for the engaging rib of the opposite combined card slot to be engaged therein.

According to the above technical means, the seat cushion of the present invention is composed of a central cushion body and a ring body, so that the center cushion body and the ring system can be colored differently to improve the appearance and variability of the seat cushion appearance, and After disassembling the center pad body and the ring body, the space required for the seat cushion transportation and storage can be reduced, and the utility of the seat cushion as a whole can be improved.

The present invention relates to a multi-turn assembly pad, please refer to FIG. 1 to FIG. 3, as can be seen from the figure, the assembly pad of the present invention mainly comprises a disc-shaped central pad 10 and at least An annular ring body 20 is disposed on the outer periphery of the center pad body 10, wherein the center pad body 10 and the ring body 20 are in an inflatable structure, so that the center pad body 10 and each ring body 20 can be An aeration nozzle 102, 202 is separately provided. In the first embodiment of the present invention, a ring body 20 is taken as an example. The ring body 20 is sleeved on the outer periphery of the center pad body 10 on the outer circumferential surface of the center pad body 10. A combination of the card slot 12 is formed in the upper recess, and the cross section of the combined card slot 12 is concavely curved. An annular locking rib 14 is respectively protruded from the upper and lower edges of the inner surface of the combined card slot 12, and the ring body is further formed on the ring body. 20 inner circumferential surface convexly provided with a combined convex portion 22, the combined convex portion The 22 series can be inserted into the combination card slot 12 of the center pad body 10, and the cross section thereof can be curved and convex. By the mutual engagement of the combination card slot 12 and the combination protrusion 22, the center pad body 10 can be The ring bodies 20 are coupled to each other, and an annular locking groove 24 is formed in the upper and lower edges of the outer surface of the combined convex portion 22 for the carding rib 14 of the center pad body 10 to be engaged therein. The mutual engagement of the rib 14 and the locking groove 24 makes the bonding strength between the center pad 10 and the ring body 20 more stable.

Thus, since the seat cushion of the present invention is composed of a center cushion body 10 and at least one ring body 20, the center cushion body 10 and the ring body 20 can be manufactured in different colors, or the center cushion of the same color can be made. The body 10 and the ring body 20 of different colors are combined into a seat cushion of different color combinations, thereby improving the variability and the aesthetic appearance of the seat cushion, and because the center cushion body 10 and the ring body 20 are relatively detachable, the borrowing body can be borrowed. This reduces the overall transport and storage space of the seat cushion and improves the overall utility.

Referring to FIG. 4, it can be seen that the second embodiment of the present invention includes two ring bodies 20, 20A, wherein the innermost ring body 20A is combined with the center pad body 10A. The outer ring body 20 is sleeved on the ring body 20A of the inner ring, and the inner circumferential surface of the inner ring 20A is convexly provided with a card slot 12A which can be combined with the central pad body 10A. The combination of the convex portion 22A and the outer circumferential surface of the ring body 20A is recessed with a combination card slot 26A. The structure of the combination card slot 26A is the same as that of the central pad body 10A combination card slot 12A, and will not be further described herein. The inner peripheral surface of the outer ring body 20 is convexly provided with a combined convex portion 22 which is engaged with the combined card slot 26A of the inner ring body 20A, whereby the combined card slots 12A, 26A and the combined convex portions 22A, 22 are utilized. The mutual engagement of the ring bodies 20, 20A and the center pad body 10A forms a disc-shaped seat cushion.

In addition, please refer to FIGS. 1 to 5, and a long arc-shaped lifting hole 28 extending through the ring body 20 is disposed on the outermost ring body 20, thereby facilitating the user to lift or move the seat cushion, and the outermost The thickness of the ring body 20 can be tapered by the inner peripheral surface of the inner peripheral surface, and a plurality of convex grains 104, 204 can be respectively protruded from the upper surface of the central body 10, 10A and each of the ring bodies 20, 20A. Sitting on the seat cushion, the user has a massage effect, and the combination of the center cushion body 10, 10A and the ring body 20, 20A, the card slot 12A, 26A and the group The positions of the convex portions 22, 22A can also be exchanged with each other, that is, a combined card groove is formed on the inner circumferential surface of the ring bodies 20, 20A, and a combined convex portion is formed on the outer circumferential surfaces of the center pad body 10, 10A and the ring bodies 20, 20A. The same combination of the central body 10, 10A and the ring body 20, 20A can be achieved to improve the elasticity of the seat cushion manufacturing.

Please refer to FIG. 5 and FIG. 6. As can be seen from the figure, a sleeve hole 106 penetrating through the center pad body 10B is further disposed on the center pad body 10B, so that a plurality of seat cushions can be used on the center pad body 10B. The sleeve hole 106 is sleeved on a column, and the plurality of seat cushions are stacked on the column body to facilitate the storage of the cushion body and reduce the overall required storage space.

It is apparent that the various modifications and changes can be made without departing from the spirit and novel concept of the invention, and the specific embodiments disclosed herein are not intended to limit the invention. All modifications in the scope of the appended patent application.
