Abstract

The utility model relates to a function development device for children, in particular to a foot-operated seesaw with sound function. The seesaw includes a base and a balance board fixedly connected with the base. The base is a cylindrical structure, and sound tubes are fixedly arranged at both ends of the balance board. Through such a design, children with vestibular dysfunction can practice to improve their physical coordination ability. The sound tubes arranged at both ends of the balance board collide with the ground so that the hard particles therein collide with the sound tubes to make a sound, thereby stimulating children's judgment on timbre.

Description

A foot seesaw

technical field

The utility model relates to a function-opening device for children, in particular to a foot-operated seesaw with audio function.

Background technique

The vestibule is the main peripheral sensory organ of the balance system of the human body, and it grows in the petrous part of the temporal bone of the skull. The human ear is divided into the outer ear, middle ear and inner ear (the inner ear is also called "labyrinth"). The vestibule is in the inner ear and is one of the organs of the inner ear. The vestibule and cochlea of the inner ear are collectively referred to as auditory organs. As the name implies, they perceive position and hearing. The vestibule perceives the spatial position of the human body, and the latter is responsible for hearing. The three semicircular canals of the vestibule sense the angular acceleration of body rotation, and the sacculus and utricle sense linear acceleration. For example, even if you close your eyes and don’t look out the window while sitting in a moving car, you can still feel the acceleration, deceleration or turning of the car; another example is the feeling of rising and falling when taking an elevator, which are all sensed by semicircular canals and otoliths. . Vestibular receptors perceive the position of the human body in space and its position changes, and transmit this information to the central nervous system, which mainly produces two physiological effects: on the one hand, it adjusts the changed position and posture of the human body to maintain the balance of the human body; on the other hand, it Participate in the regulation of eye movement, so that the human body maintains clear vision during body position changes and movements, so it plays an important role in maintaining our posture balance and clear vision.

When there is a functional disorder in the vestibule of the human body, the most direct manifestation is the deterioration of the balance ability of the human body. Especially for children born by cesarean section, vestibular dysfunction is prone to occur, which manifests as insufficient crawling, poor concentration, restlessness, lack of coordination of movements, clumsiness, lack of balance, and easy falls in early childhood.

Contents of the invention

The task of the utility model is to provide a foot-operated seesaw that can train the development of children's vestibule, and can promote the coordination of the whole body and cultivate children's sense of rhythm. The pedal seesaw includes: a base and a balance board fixedly connected with the base, characterized in that: the base is a cylindrical structure, and sound tubes are fixedly arranged at both ends of the balance board.

A further improvement is that the base is composed of an arc-shaped planar plate and a cylindrical piece placed inside the arc-shaped planar plate, the projection of the arc-shaped planar plate on a plane perpendicular to the axis is in the shape of a superior arc, and the balance The plate is fixedly connected with the curved plane plate.

A further improvement is that the cylindrical member is composed of two circular bottom panels and a connecting shaft connecting the two circular bottom panels.

A further improvement is that the balance board is provided with foot pads on both sides of the base.

A further improvement is that the foot pad is higher than the balance board.

A further improvement is that the sound tube, the balance board and the arc-shaped plane board in the base are made of bamboo wood.

A further improvement is that the sound cylinder is composed of a hollow cylindrical member and hard particles placed in the hollow cylindrical member, and the axial direction of the sound cylinder is parallel to the axial direction of the cylindrical member.

A further improvement is that an elastic member is sheathed on the outer circumference of the sound cylinder.

A further improvement is that the sound tube is provided with an openable and closable cover.

After adopting such a design, children can unnaturally improve their sense of balance and rhythm during play. In addition, because it is made of bamboo and wood, it is light in weight and easy to carry. In addition, the sound tube can be filled with any hard particles during use, which can produce different timbres, which is beneficial for children to improve their ability to distinguish timbres and music appreciation.

Detailed ways

Below with reference to the accompanying drawings, through the description of the embodiments, the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part involved in the specific implementation of the utility model are made. Further details.

As can be seen from the three views of the pedal seesaw shown in FIGS. The base 10 is composed of a detachable arc-shaped plane plate 12 and a cylindrical member 14, wherein the arc-shaped plane plate 12, the balance plate 20 and the sound tube 30 are integrally made. The arc-shaped planar plate 12 has a superior arc structure, so that the cylindrical member 14 can be locked in the accommodation space formed by the arc-shaped planar plate 12, thereby improving the safety and reliability of the entire seesaw. As shown in FIG. 4 , the cylindrical member 14 is composed of two circular bottom panels 16 which have a good fit with the arc-shaped flat panel 12 and a connecting shaft 18 connecting the two circular bottom panels 16 . Such a design can effectively reduce the overall mass of the seesaw, so that children can easily move the seesaw.

Shown in Figures 1, 2, and 3, sound tubes 30 are respectively installed at both ends of the balance plate 20, and the sound tubes 30 are designed as hollow cylindrical structures whose axis is parallel to the axis of the cylindrical part 14, and in Hard particles are contained in the sound tube 30 to generate sound when the seesaw moves up and down. In order to prevent the sound tube 30 from being damaged due to excessive force when the seesaw moves up and down, several rubber bands are wound around the outer circumference of the sound tube 30 to reduce the damage to the sound tube 30 caused by the impact pressure.

The balance board 20, the arc-shaped flat board 12, and the sound tube 30 are made of bamboo and wood. In order to avoid the balance board 20 being too smooth due to the friction of shoes after long-term use, two rubber pads are set on the place where people's feet step on. , which can ensure that children can stand on the balance board 20 stably. In addition, the sound tube 30 is opened and locked by twisting, so that different types of hard particles can be replaced according to needs, thereby producing different timbres to exercise children's timbre recognition ability, and can also stimulate children's awareness of the pronunciation rules of different substances. curious. In addition, the balance board 20 can be sprayed with different colors to stimulate children's curiosity about colors.

Of course, the cylindrical member 14 can also be fixed by means of mortise jointing or glue jointing of the circular bottom panel 16 and the arc-shaped plane plate 12 . In addition, the foot pad can also be designed as a fixed shoe cover to prevent slipping.
