  • Publication number: 20230404845
    Abstract: A foam stick includes a tube body, a core, and two covers. The tube body has an accommodating groove with two open ends. The core is disposed in the accommodating groove of the tube body. The two covers are disposed at both ends of the tube body to close the accommodating groove. The foam stick is composed of the tube body, the core and the covers, so the material utilization rate is high. Through the combination of the tube body, the core and the covers, the foam stick has different characteristics and can be used as rollers or floats.

  • Publication number: 20230405405
    Abstract: A balance pad includes a base. A plurality of first pillars and a peripheral wall are uprightly disposed on the base. The peripheral wall surrounds the first pillars so that the first pillars are located within the peripheral wall. Thereby, the first pillars reduce the stability of the balance pad to increase the difficulty of doing balance exercise. The peripheral wall surrounds the first pillars, so that the first pillars can abut against the peripheral wall to avoid excessive inclination of the first pillars to cause injury to a user.

  • Patent number: 11573610
    Abstract: A rotary shaft link assembly structure is connected between a first support and a second support of two articles. The rotary shaft link assembly structure has a rotary shaft assembly and at least one synchronous rotational assembly. The rotary shaft assembly has multiple connection members side-by-side disposed between the first and second supports. Each connection member is correspondingly formed with at least one hollow section. The synchronous rotational assembly passes through the hollow sections of the connection members to respectively connect with the first and second supports, whereby the connection members are transversely serially connected to drivingly bend and connect along with the synchronous rotational assembly. The connection members respectively shield a part of the synchronous rotational assembly to provide a protection effect and reduce the dropped powder and oil leakage caused by the friction.
