A portable canopy can comprise a portable frame, a portable cover, an electrical power system and can transition between an installed and transport state. The portable cover can be made from a flexible, water-resistant fabric. The electrical power system can be integrated into the portable frame, which includes a connection point for receiving power from an extra low-voltage external power source. In the installed state, a first volume under roof shelters objects. The portable frame can provide a support structure for the first volume and the portable cover. In the installed state, the electrical power system can be connected to the external power source to provide electric power to electric accessories via direct contact with a designated area of an exterior surface of a power-conveying member of the portable frame. The transport state can have a second volume at least five times less than the first volume.

The present invention provides a flow-guiding device, comprising: a flow-guiding passage, a plurality of a first control valves, a flow-guiding bag and a flow-guiding tube. One end of the flow-guiding passage is connected to a flow-guiding opening and the other end of the flow-guiding passage is connected to a plurality of first control valves. The plurality of first control valves are further connected to the flow-guiding bag, which is connected to one end of the flow-guiding tube. By opening the plurality of first control valves, the fluid coming down from the flow-guiding opening is directed to flow into the flow-guiding bag, and by closing the plurality of first control valves. The other end of the flow-guiding tube is connected to a second control valve; by opening the second control valve, the fluid inside the flow-guiding bag is discharged. The present invention also provides an umbrella having a flow-guiding device.

An umbrella case configured to hold an umbrella having a rigid shaft with a handle at one end and a spike at the other end, the umbrella case comprising an umbrella holding assembly comprising a generally tubular sheath 106 having an open end and a spike-receiving portion 107 defining a spike-receiving aperture at the other end, and a fastening strap 100 having a first end coupled to an outer surface of the umbrella case, close to the open end of the sheath 106, and having a second, free end configured to be selectively moved to a fastening position in which it is connected to the umbrella case at a generally diametrically opposite location to the first end, the sheath, the spike-receiving portion and the fastening strap when in the fastening position, together, defining the effective length of the umbrella holding assembly, wherein at least one of the sheath, the spike-receiving portion and the fastening strap is selectively longitudinally extendible upon application of a force, in use, thereby to increase the effective length of the umbrella holding assembly to accommodate the length of an umbrella held therein.

A stretchable bottle container comprising a stretchable bottle body, a bottle cap, and portable hanging accessories, useful as an umbrella accessory, or as a packaging and storage container. The body of the stretchable bottle is a cylinder which has one closed end and one open end, and the wall of the cylinder contains stretchable wavy structures. The open end of the stretchable bottle body is connected with the bottle cap through a detachable tightening seal connection which is airtight and waterproof. The size difference between diameters of the opening of the bottle and that of the body (1) is less than 10%. The open end of the bottle body is soft and deformable under inward pressure of finger squeezes. Hanging accessories for portability are connectable with the bottle cap through a sectional structure with capability of repeated detachments and re-attachments or through a hanging carabiner which has open and shut configurations. The present utility invention provides a stretchable bottle container with technical advantages of having a wide mouth opening with waterproof and airtight insulation while being soft and deformable under finger squeezes, compactness with compressible volume, easiness in portability and compatibility for different sizes.

A multi-functional activity management system for elderly utilizes prior art walking sticks to manage big data related to activity of elderly persons. In addition, new improvements have been made upon prior art walking sticks. By incorporating umbrella function into the walking stick, the stem portion becomes narrower and shorter, thereby making it easy to be inserted into the thin walking stick. New functions have been developed from the prior art walking sticks for better use by the elderly persons.
