An umbrella system includes a support pole connected to a rotating tube positioned around a center tube that extends between the support pole and a center support that is connected to an umbrella frame. The rotating tube has one or more helical grooves therein that are engaged by teeth of a hub which is connected to the umbrella frame. As the rotating tube is rotated, the hub is driven along the length of the rotating tube thereby opening and closing the umbrella frame. In one arrangement system includes a motor housing assembly including a plurality of batteries and a motor that includes a driven gear that meshes with a stationary gear which causes rotation of the rotating tube.

Systems, methods, and computer-readable storage devices for providing directions haptically such that sight and hearing can continue unimpeded. In one exemplary embodiment, a wearable device (such as earphones, ear rings, gloves, glasses, or other wearable objects) configured as disclosed herein receives directions to an intended destination for a user, the directions comprising a movement action and a distance to the movement action. The wearable device has multiple haptic output units and generates, through one of those units, a haptic output based on the directions. This allows the user to receive the directions through touch rather than looking at their mobile device or from audio.

In one or more arrangements, an umbrella system includes a support pole connected to a rotating tube positioned around a center tube that extends between the support pole and a upper hub that is connected to an umbrella frame. The rotating tube has one or more helical grooves therein that are engaged by a lower hub which is connected to the umbrella frame. As the rotating tube is rotated, the lower hub is driven along the length of the rotating tube, thereby opening and closing the umbrella frame. In one or more arrangements, the system includes a rotational lock assembly configured to prevent rotation of the rotating tube when locked and permit rotation of the rotating tube when unlocked. In one or more arrangements, the system includes a counterbalance assembly that provides a counterbalance force positioned within a upper hub of the umbrella frame.

An umbrella including a support shaft, a plurality of ribs, a rotatable cam assembly, and a canopy. Each rib of the plurality of ribs has a proximal end portion and a distal end portion. The proximal end portion is pivotably attached to an upper portion of the support shaft to pivot the rib between an open position and a closed position. The rotatable cam assembly includes a cam configured to rotate about a longitudinal axis of the support shaft. The cam is engaged with each rib of the plurality of ribs such that (i) each rib moves in a direction from the closed position to the open position when the cam rotates in a first direction and (ii) each rib moves in a direction from the open position to the closed position when the cam rotates in a second direction, the second direction being opposite the first direction.

A tilt device for an umbrella is a guide track assembly disposed in one of a first tilt member and a second tilt member. The guide track assembly has a first guide track member and a second guide track member. An enclosed guide track is within the guide track assembly. The guide track assembly is slideably received within the first tilt member. A driver that has an upper portion disposed in the second tilt member and a lower portion. The lower portion is disposed in the enclosed guide track. The enclosed guide track is configured to guide movement of the lower portion of the driver within the first tilt member. Movement of the driver causes the second tilt member to tilt relative to the first tilt member. The guide track assembly includes an open channel forming a part of a cord channel through the tilt device.

A snap-in crank mechanism comprising a crank housing mounted out of a column, and a crank having a crank rod with two ends; the crank housing comprises a crank inner housing sleeved outside the column, and a crank outer housing detachably sleeved outside the crank inner housing; the crank inner housing has a left inner housing, a right inner housing and a lower inner housing, the left inner housing and the right inner housing are connected with each other forming a sleeve which is sleeved outside the column and has a crank rod mounting hole at the periphery of the sleeve; the crank outer housing is slidable on the periphery of the sleeve formed by the left inner housing and the right inner housing; the lower inner housing is inserted from the bottom of the crank outer housing, and is located between the crank outer housing and the bottom of the left inner housing and the right inner housing clamping with the left inner housing and the right inner housing; one end of the crank rod is located inside the crank rod mounting hole and is connected to the crank shaft running through the column, while the other end of the crank rod is connected to the crank head. The jacket of the crank head is made of natural rubber. The present invention is simple and reasonable in structure, easy to dissemble and assemble and aesthetic in appearance, and can satisfy the requirement of replacing many types of housings, improve the user’s comfort in use and improve the production quality and the user experience.
