Description

Folding table and chair

The utility model relates to the field of pet products and human daily necessities, in particular to a folding table and chair.

Background technique

Melamine is called melamine, melamine or melamine resin. The transliteration name is "Melvin". Melamine is a special material with the following properties and advantages. 'Melamine' is a combination of ceramics and plastics. It is popular internationally. Tableware, safe, non-toxic and tasteless; hard, resistant to sputum, low breakage rate, impact resistance; acid, alkali and various solvents have superior resistance; smooth surface, easy to wash; good temperature resistance (- 20OC—+120OC); specific gravity is 1.6, with moderate weight; the surface is beautifully printed, the bright pattern is not easy to peel off; the thermal conductivity is low.

The BMC (DMC) material is an abbreviation for Bulk (Dough) molding compounds, that is, a dough molding compound. It is often referred to as unsaturated polyester bulk molding compound in China. It has excellent electrical properties, mechanical properties, heat resistance, chemical resistance, and adapts to various molding processes to meet the performance requirements of various products. BMC and Melamine are similar in terms of molding process and performance, and are limited by the production process. Generally, the products produced are not complicated and the structure is relatively simple.

Embodiment 1:

This embodiment provides a foldable table and chair, as shown in FIG. 1 to FIG. 3, which is composed of the following three parts:

1. Countertop made of Melamine, BMC or plastic material 1: There are two recesses 11 on the table for placing the stainless steel bowl 4 or for directly using food or water. The upper surface of the table has a raised upper circumference. The edge 12 can prevent the food from falling to the ground, and the bottom surface of the table top is also provided with a downwardly protruding lower edge 13 which acts as a reinforcing rib to strengthen the strength of the whole product, and the four corners of the lower edge 13 have The raised ear 14 has a hole 15 formed in the ear 14, the upper portion of the outer surface of the ear 14 is provided with a raised platform 16, and the lower portion is provided with a concave track 17.

2. Two support legs 2 made of Melami _ne , BMC or plastic material: they are respectively mounted on the lower ends of the table top 1, each support leg 2 is U-shaped, and the bottom ends are two Supporting legs 21, the opposite inner sides of the upper portion respectively have a column 22 which protrudes toward the opposite side, and the column 22 serves as a rotating shaft corresponding to the hole 15 in the ear 14 protruding from the four corners of the table 1 while the two The inside also has a raised platform 23 which corresponds to the raised platform 16 on the ear 14 of the table 1 .

When the table top 1 is assembled with the support leg 2, it is inserted through the elastic hard support of the support leg 2, and the concave track 17 on the surface of the ear 14 of the table top 1 has a certain inclination, and the support leg 2 The column 22 also has a slope on it, which makes it easier to fit the support leg 2 into the table 1 through the recessed track 17. When the support leg 2 is opened, the raised platform 23 on both inner sides of the support leg 2 and the raised platform 16 on the mesa ear are in a state of mutual engagement, so that the support leg 2 can be stably opened and positioned It will not easily fold back the support leg 2.

When opened, the force plate support leg 2, the platform 23 protruding on the inner side of the support leg 2 and the platform 16 protruding from the outer surface of the lower ear of the table top 1 are rotated by the column 22 itself, and the two objects are rubbed, the inner two bosses 16 23 encounter overlap, so that the elastic support legs 2 (U-shaped) are spread on both sides, when turned to a certain angle, The two objects inner friction surface convex platforms 16, 23 are misaligned so that the elastic U-shaped support legs 2 are returned to both sides, so that the positioning of the support legs 2 is achieved by the convex-concave principle, and it is not easy to fold back.

When folded, the principle is similar to that of opening, except that the direction of rotation is reversed and it is not easy to open.

3, anti-slip mat 3: It is made of silicone rubber, installed at the bottom of the support leg 21, can play the role of anti-skid and shockproof.

Embodiment 2:

This embodiment provides a foldable table and chair of another structure, as shown in Fig. 4, the structure of which is similar to that of the first embodiment, except that the design of the joint portion of the support leg and the table is slightly different. details as follows:

The inner side of the two supporting legs 20 respectively has a protruding column 202 as a rotating shaft, and a corresponding triangular surface of each of the two supporting legs 20 is respectively provided with a triangular convex platform 203. The triangular raised platforms 203 are symmetrical to each other. The four corners of the mesa 10 are respectively provided with protruding ears 101, each of which has a blind hole 102, and each of the blind holes 102 is further provided with two triangular recesses 103 of the same shape (blind holes or The size and position of the four blind holes 102 correspond to the size and position __ of the four studs 202 of the two support legs 20. The triangular projection platform 203 corresponds to the shape and size of the triangular recess 103.

When assembled, the triangular raised platform 203 on the stud 202 engages with the triangular recess 103 in the ear 101 of the table 10, and the support leg 20 is distracted and positioned. When folded, the support leg 20 is forcedly pulled, and the triangular raised platform 203 on the boss 202 of the support leg 20 overlaps with the blind hole 102 on the ear 101 of the table 10 to overlap, so that the elastic support legs 20 are stretched on both sides. When turned to a certain angle, the triangular raised platform 203 of the support leg 20 meets another triangular recessed hole 103 on the ear 101 of the table top 10, and the support legs 20 are returned to each other due to the elasticity of the support leg 20, thereby passing through the convex and concave The principle realizes the positioning of the support leg 20, and is not easy to fold back. When finding the opening, the principle is similar to that when folding.

In the above two embodiments, the recess may have a bottom surface or no bottom surface.
