Description

The technical solution relates to the field of intellectual toys, in particular to the corner block of a puzzle cube.

State of the art

In the prior art, angular blocks of three-dimensional puzzle cubes are known, comprising a housing with a removable lid and a rack with an extended lower section. The rack with the extended lower section is a solid part, motionlessly connected to the housing.

From the patent CN 206372506 U, publication 2017.08.04, IPC A63F 9/08 (2006/01), a corner block of a puzzle cube is known, the rack of which is made of complex shape with two rows of protrusions for connection with the body of the corner block.

As the closest analogue, the corner block of the puzzle cube, known from CN 206334324 U, publication July 17, 2017, IPC A63F 9/08 (2006/01), was chosen. The stand is made trihedral and contains a longitudinal groove in each face. In the lower part of the housing there are three protrusions that are in the form of the above-mentioned grooves. In the process of connecting the rack to the housing, the protrusions of the housing are located in the longitudinal grooves of the rack.

The disadvantages include the ability to disconnect the rack from the housing, which reduces the reliability of the cube, especially when it is assembled quickly.

Utility Model Disclosure

The technical result is to increase the reliability of the corner block of the cube.

The specified technical result is achieved in the corner block of the cube containing the casing, the rack with the lower expanded section, while the upper section of the rack is placed in the hole bounded by the central protrusion made inside the housing, according to the utility model, the upper section of the rack is equipped with hooks in contact with their lower sections with the surface of the end part of the Central protrusion of the housing, while in the specified upper section of the rack longitudinal slots are made, between which the longitudinal section is located, ending one of these hooks.

Each hook extends beyond the surface of the end part of the upper portion of the rack.

Each hook extends beyond the outer surface of the upper portion of the strut.

A longitudinal slot is made in the costal zone of the upper portion of the rack.

The hooks may have an L-shaped or arched, or U-shaped profile.

The set of features of the inventive corner block of the cube is in a causal relationship with the achieved technical result and is presented in the formula of the utility model.

The essence of the technical solution is illustrated by figures.

It should be understood that specialists in the art will be able to offer other options for implementing the utility model and that some of its details can be changed in various other aspects, without going beyond the essence and scope of the present utility model. Accordingly, explanatory figures and a detailed description of the corner block of the cube are illustrative, but not restrictive.

The corner block 1 of cube 2 contains: a housing 3, a cover 4 and a rack 5 with an upper section 6 and an expanded lower section 7 (see figures 1-3).

In the lower part of the housing 3, a central protrusion 8 is formed, located inside the said housing 3 and forming an opening 9 for installing the upper portion 6 of the rack 5 (see figures 4, 5). The central protrusion 8 is multifaceted, respectively, and the hole 9 has a multifaceted contour in cross section.

In a specific embodiment, the housing 3 is made integral and hollow, the central protrusion 8 is formed by three faces, the inner surface of which limits the opening 9.

The upper portion 6 of the rack 5 is provided with hooks 10, each of which may protrude beyond the surface 11 of the end portion and the outer surface 6a of the upper portion 6 of the strut 5. Each of the hooks 10 comprises a lower portion 10a for contacting the surface 12 of the end portion of the central protrusion 8, which eliminates the disconnection of the rack 5 from the housing 3 of the corner block 1 (see figures 3, 5).

Advantageous is the implementation of the hook 10 on each face of the upper section 6 of the rack 5.

The hooks 10 may have an L-shaped or arched, or U-shaped, or other shape profile.

The upper section 6 of the rack 5 from the outside should have the shape of the mating hole 9 of the Central protrusion 8, which will ensure tight contact of the upper section 6 with the Central protrusion 8.

In the assembled position of the corner block 1, the upper portion 6 of the strut 5 is tightly mounted in the hole 9 of the central protrusion 8 of the housing 3, with each of the hooks 10 resting on its surface 12 of the end portion of the central protrusion 8 with its lower portion 10a, which prevents the strut 5 from leaving the housing 3.

In the upper section 6 of the rack 5, longitudinal slots 13 are made, between which there is a longitudinal section 14 ending with a hook 10. In the rib zone of the upper section 6 of the rack 5, a longitudinal slot 15 can be made. These longitudinal slots 13 and 15 allow the longitudinal section 14 and two other faces with hooks 10 to deviate slightly towards the longitudinal axis L of the rack 5 during the passage of the upper section 6 through the hole 9 of the Central protrusion 8. After the hooks 10 come out of the hole 9 of the Central protrusion 8, the longitudinal portion ok 14 takes its initial predetermined position, and the hooks 10 are in contact (mating) with their lower sections 10a with the surface 12 of the end part of the specified Central protrusion 8. Thus, a tight fit of the hooks 10 on the surface 12 of the end part of the Central protrusion 8.

It is possible that longitudinal slots 13 can be made in each face of the upper section 6, and longitudinal slots 15 in each corner zone of the specified upper section 6 of the rack 5, or a combination thereof.

Inside the housing 3, local protrusions 16 can be formed with holes 17 for mounting mating protrusions 18 formed on the inner surface of the cover 4 of the corner block 1. The cover 4 is formed by faces 4a, the outer surfaces of which are painted in different colors.

The mounting design of the rack 5 with the housing 3 of the corner block 1 can be used in the construction of various puzzle cubes containing corner blocks.

The above-described design of the corner block 1 eliminates the possibility of disconnecting the rack 5 from the housing 3, which increases the reliability of the above-described corner block 1 and, accordingly, the cube 2 as a whole.

The above-described design of the corner block 1 is technologically advanced in its manufacture and assembly.
