DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is an exploded view, FIG. 2 is a schematic perspective view, and FIG. 3 is a bottom view of a portable standing desk device 100 in examples of the present disclosure. The portable standing desk device 100 comprises a top board 110, a first block assembly 122 having a first groove 132, a second block assembly 124 having a second groove 134, a third block assembly 126 having a third groove 136, a fourth block assembly 128 having a fourth groove 138, a base panel 160, and another base panel 180. The top board 110 has a top surface 112 and a bottom surface 114. In FIG. 4, a second side surface 418 of the top board 110 is opposing the first side surface 416 of the top board 110. In FIGS. 1-3, top surfaces of the first block assembly 122, the second block assembly 124, the third block assembly 126, and the fourth block assembly 128 are attached to the bottom surface 114 of the top board 110. The base panel 160 has an open ended slot 164 extending upwardly from a bottom surface of the base panel 160. The base panel 180 has an open ended slot 184 extending downwardly from a top surface of the base panel 180. In one example, each of the open ended slot 164 and the open ended slot 184 is a slanted cut done by an angled rotary blade.

In one example, the top board 110, the four separated block assemblies 122, 124, 126, and 128, and the base panels 160 and 180 are made of paper boards. In another example, the top board 110, the four separated block assemblies 122, 124, 126, and 128, and the base panels 160 and 180 are made of a plastic material.

In one example, the four separated block assemblies 122, 124, 126, and 128 are glued to the top board 110. In another example, the four separated block assemblies 122, 124, 126, and 128 are nailed to the top board 110. In still another example, the four separated block assemblies 122, 124, 126, and 128 are attached to the top board 110 by tapes. In one example, each of the four separated block assemblies 122, 124, 126, and 128 is a two-piece constructed assembly. A first piece and a second piece are separated by a groove. In another example, each of the four separated block assemblies 122, 124, 126, and 128 is a one-piece constructed assembly. A single piece having a groove in a middle region facing downwardly.

In examples of the present disclosure, the base panel 160 and the base panel 180 have the same length, width, and thickness. The first open ended slot 164 and the second open ended slot 184 have the same length, width, depth and angle. In one example, the length of the base panel 160 is the same as the diagonal length of the bottom surface 114 of the top board 110. In another example, the length of the base panel 160 is shorter than the diagonal length of the bottom surface 114 of the top board 110.

In examples of the present disclosure, a length of the first open ended slot 164 is longer than a half of a height of the base panel 160 and a length of the second open ended slot 184 is longer than a half of a height of the base panel 180.

The base panel 160 has a width W162. The base panel 180 has a width W182. In examples of the present disclosure, the width W162 is the same as the width W182. In one example, the width W182 is smaller than a width of the second groove 134. In another example, the width W182 is the same as the width of the second groove 134. The four grooves 132, 134, 136, and 138 hold the base panels 160 and 180 by friction. In still another example, the width W182 is larger than the width of the second groove 134 and, in an assembled condition, a portion of the base panel 160 is press-fitted into the second groove 134. Another portion of the base panel 160 is press-fitted into the fourth groove 138. A portion of the base panel 180 is press-fitted into the first groove 132. Another portion of the base panel 180 is press-fitted into the third groove 136.

In examples of the present disclosure, during an assembling process, the first open ended slot 164 is aligned vertically with the second open ended slot 184. The base panel 160 slides downwardly and interlocks with the base panel 180. Therefore, in an assembled condition, the base panel 160 and the base panel 180 form a base having a letter X shape.

In examples of the present disclosure, in an assembled condition, a top surface of the base panel 160 and a top surface of the base panel 180 contact the bottom surface 114 of the top board 110.

The first groove 132 and the third groove 136 are diagonally opposed. The second groove 134 and the fourth groove 138 are diagonally opposed. The imaginary rectangle 310 has a length L340 and a width W320. A slenderness ratio of the imaginary rectangle 310 is represented by the length L340 divided by the width W320. An acute angle A360 in degrees between a normal direction of a side surface of the base panel 160 and a first side wall of the open ended slot 164 is determined by a mathematical expression {2×[arctangent(L/W)×180/π]−90}. L is the length L340. W is the width W320. π is a mathematical constant, a ratio of a circle's circumference to a diameter of the circle. Arctangent is an inverse trigonometric function. In one example, L is larger than W. In one example, L is 100 centimeters. W is 80 centimeters. A360 is 12.68 degrees. In another example, L is 100 centimeters. W is 70 centimeters. A360 is 20.02 degrees. In one example, a properly determined acute angle A360 provides a tighter grip between the base panels 160 and 180.
