  • Patent number: 9407124
    Abstract: A motor frame comprising four side surfaces, built-up portions and leg members is provided. The four side surfaces define the outer circumference of the motor frame. The four side surfaces include a terminal box mounting surface on which a terminal box is provided and two side surfaces located on respective sides of the terminal box mounting surface. The built-up portions are provided on each of the two side surfaces, wherein two or more bolt holes can be formed on the built-up portions. The built-up portions are configured such that any of hanging bolts or the leg members can be fastened to the built-up portions. The hanging bolts are screwed into bolt holes formed on one of the two side surfaces and the leg members are fastened to bolt holes formed on the other of the two side surfaces.

  • Patent number: 9083214
    Abstract: A motor includes: a rotor including an output shaft; a stator provided with a coil wound around the stator; and a casing configured to accommodate the rotor and the stator and to contain a coolant liquid therein, wherein skews are formed in at least one of the rotor and the stator. A hollow portion extending an axial direction is formed in the output shaft. The hollow portion includes an opening that opens in the casing at an end surface of the output shaft where a liquid surface of the coolant liquid is relatively higher due to rotation of the rotor and that communicates with the casing near an end opposite to the end surface.

  • Patent number: 7331903
    Abstract: A trampoline (10) includes a base frame (14) having a substantially non-rectangular perimeter region (38), a bed suspension assembly (16) and a bed (12). The bed (12) is coupled to the base frame (14) with the bed suspension assembly (16). Further, the bed (12) includes a first pair of substantially parallel sides (34A, 34B). For example, the bed (12) can be rectangular in shape, or can include a second pair of arc-shaped sides (36A, 36B). The perimeter region (38) can be substantially oval-shaped or circular-shaped. The trampoline (10) can also include one or more side sections (18, 22) and one or more side suspensions (20, 24) that couple the side sections (18, 22) to the base frame (14). In one embodiment, the side sections (18, 22) each include an inner side (54, 58) that is substantially linear and an outer side (56, 60) that is substantially arc-shaped.

  • Publication number: 20070232456
    Abstract: A trampoline assembly (10) for use by a user (233) includes a base frame (12), a suspension assembly (14) and a bed assembly (18). The suspension assembly (14) includes a plurality of suspension members (26) that couple the bed assembly (18) to the base frame (12). In one embodiment, the bed assembly (18) defines a contact surface (28) that is engaged by the user (233). Further, the contact surface (28) includes a plurality of spaced apart projections (30). The feet of the user (233) of the trampoline assembly (10) engage the projections (30) during use of the trampoline assembly (10). As a result thereof, the feet of the user (233) receive a massage like action. This causes increased blood flow in the feet, releases tension in the feet and stimulates the brain and internal organs.
