Description

A kind of easy to bend piece A kind of easy to bend piece

 Technical field

 The invention relates to the field of toy puzzles, and more particularly to a flexible piece.

 Background technique

The three-dimensional puzzle piece in the prior art has a bendable piece for use as a corner of a three-dimensional puzzle, but these currently available bent pieces are formed by forming a groove-like structure on the inner side. However, the current groove structure is a triangular groove type, and the disadvantage of these structures is that the precision of the processing is high, so that the bent piece is exactly the desired angle. Otherwise, the piece is easily deformed and opened, resulting in serious deformation of the corner of the three-dimensional puzzle, not the required angle, and it is impossible to splicing the beautiful three-dimensional effect.

 Summary of the invention

The technical problem to be solved by the present invention is to design a new bent piece structure which can overcome the defects of the prior art bending piece and provide a piece which has a good bending angle and is convenient for bending.

 This patent achieves the above object by the following technical solutions.

The patented design facilitates bending of the piece, including two pieces of unit pieces joined together, and the improvement is that the unit piece is connected to the outer side by a sheet having a certain width, and the two pieces of the unit piece are connected to the inner side of the piece. It is groove-shaped and has a flat outer shape. The above structure connects the two unit pieces by a sheet having a certain width, so that the bending between the unit pieces has a certain tolerance and can be used for a certain deformation, so the production precision does not need to be very precise. Due to the presence of the sheet, the corners are not deformed by the internal stress after the puzzle is formed, and the corners having a certain rounded transition can be formed on the outside after the bending, which makes the three-dimensional puzzle more beautiful.

 The above structure can be further improved as follows:

 An inclined surface is formed on one side of the two-piece unit piece connecting sheet.

 The two unit pieces form a groove having a trapezoidal cross section through the portion where the sheets are joined.

 The two apex angles of the trapezoidal grooves are rounded.

 After the bending of the bent piece is facilitated, the outer side of the joint of the two piece pieces has a smooth transition surface.

 After the bending of the bent piece is facilitated, a teardrop-shaped through hole is formed inside the joint of the two unit pieces.

 The unit tile has four sides, except for one side of the connection, the other three sides are straight sides or grooves or bumps having an Ω shape.

 The sheet has a width of 0.3 to 1 times the thickness of the tile.

The above structure can well overcome the defects of high precision required by the existing jigsaw craft, and make it possible to produce large-scale and beautiful three-dimensional puzzles, and further reduce the cost, and can be applied in various three-dimensional puzzles, and has wide market application. Sex.

 Example 1

 The easy-to-bend tile shown in Figure 1 includes two pieces of unit pieces 1 and 2 joined together, the unit piece 1 And connected to the outside through a sheet 3 having a certain width, the two unit pieces 1 and 2 are in a groove shape on the inner side of the joint position, and the outer side is flat, and as shown in Fig. 4, the sheet is not visible from the outside. shape.

 The unit tiles 1 and 2 have four sides, except one side of the connection, one of which is a continuous straight side and the other two sides have an Ω Grooves or bumps for connecting to other tiles. The width of the sheet is 0.6 The thickness of the double piece can of course be adjusted according to actual needs, but in order to ensure the flexibility of the puzzle without deformation and bending, the width of the sheet is generally controlled between 0.3 and 1 times the thickness of the piece.

 As can be seen from the cross-sectional view of Fig. 2, the two piece pieces 1 and 2 are connected to the sheet 3 One side of the side forms an inclined surface, and the cross section of the entire connecting portion is trapezoidal, and the two top corners of the trapezoidal groove are rounded, so that the singularity does not occur after the bending.

 The bending process is as shown by the arrow in Fig. 3. After bending, the outer surface of the joint between the two pieces of the pieces 1 and 2 is a smooth transition surface, as shown in Fig. 5. As shown, a teardrop-shaped through hole 4 is formed inside the joint of the two unit tiles 1 and 2, as shown in Figs. 5 and 6.

 Drop-shaped through hole 4 And the smooth transition surface can play the role of buffer stress deformation. After the mosaic is formed, it can accommodate a certain internal force deformation and keep the overall shape from being deformed. It can also be seen from Figure 5 that the folded sheet 3 The formation of a smooth transition corner can make the shape of the three-dimensional puzzle more beautiful.

 The structure of the present patent is not limited to the above embodiment, and specifically, different connection grooves and bumps, and sheets 3 may be designed according to the type of the tiles. The width.

 Example 2

 Figure 7 is a bendable piece with a flattened angle after the improvement of the patent. The bendable piece is composed of four pieces of unit pieces 11 and 12 which are sequentially connected. 13 and 14 are formed between the first unit tile 11 and the second unit tile 12, and between the third unit tile 13 and the fourth unit tile 14 through the sheet 5 Connecting; the second unit tile 12 and the third unit tile 13 are connected to the outside by a sheet 8 having a width, the two unit pieces 12 and 13 The inner side of the connection position is grooved and the outer side is flat. The sheet 5 is provided with two small cylinders 6 which are distributed at both ends of the sheet 5. In the first piece of the piece 11 and the second piece of the piece 12 A positioning mechanism is provided between and between the third unit piece 13 and the fourth unit piece 14. The positioning mechanism includes a block 71 disposed on the first unit tile 11 and the third unit tile 13 And a card slot 72 provided on the second unit tile 12 and the fourth unit tile 14. The unit tiles 11 , 12 , 13 and 14 It has four sides, except for the joined sides, the other sides have Ω-shaped grooves or bumps.

 Figure 8 is a schematic cross-sectional view of A-A in Figure 7, from which the first piece of the piece 11 and the second piece of the piece 12 can be seen. By connecting the connecting ridges 5, it can be seen from the enlarged view of Fig. 9 that the sheet 5 forms a groove having a W-shaped cross section on the outer side of the joint of the unit pieces, and a groove having a M-shaped cross section on the inner side.

 The structure after the above structure is bent as shown in Figs. 10 and 11, the first unit piece 11 and the fourth unit piece 14 The omega-shaped lugs and the grooves on the opposite sides cooperate with each other, and the bent block 71 and the card slot 72 are engaged with each other after the bending. Unit tiles 11 , 12 , 13 and 14 along sheet 5 and sheet 8 respectively Bend, the structure after bending is shown in Figure 11. As can be seen from the figure, the joined side of the first unit tile 11 and the second unit tile 12 after the bending presses the sheet 5 and the small cylinder 6 provided on the sheet 5 Under the support of the small cylinder 6, the outer surface of the sheet 5 can be made very flat. The original W-shaped groove was flattened to form a smooth transition surface.

The patent is not limited to the above embodiments, and those skilled in the art can increase or decrease the number of unit tiles or the number of small cylinders according to actual needs without departing from the general concept of the present technology.
