Abstract: An umbrella with a canopy rotating function comprises a central shaft, an upper nest assembly, a lower nest assembly, a canopy unit. The upper nest assembly comprises an upper nest body, a fastener and a movable upper nest. The lower nest assembly comprises a pulley seat, a lower nest body and a movable lower nest. Thus, in an opened state, the upper nest body and the lower nest body are connected and positioned, and the canopy unit can link with the movable upper nest and the movable lower nest, so that the movable lower nest and the movable upper nest synchronously rotate relatively to the central shaft.

Abstract: An operation system for umbrellas includes a multiple-section shaft with a top cap connected to a top thereof and the top cap has a first extension which includes a flexible part formed thereto. A protrusion extends from a distal end of the flexible part. A runner is movably mounted to the shaft and the first extension. The runner has a second extension which has a positioning hole so as to receive the protrusion to stop the runner from moving downward. A hollow sleeve is movably mounted to the second extension and drives the runner to move along the shaft. The sleeve has a compressing member to compress the protrusion inward to disengage the protrusion from the positioning hole when folding the umbrella.

Abstract: A collapsing mechanism for umbrellas includes a transmission member and a movable member which is engaged with the transmission member to stop the mechanism from being stopped during the action and the umbrella does not opened suddenly to hurt people. During the collapsing action, the action can be stopped as desired and the umbrella is maintained at that status and does not open. By the mechanism, the user does not need to complete the collapsing action at one time.

Abstract: A two-stage collapsing device includes a base having a passage with first and second slots defined in an inner periphery thereof. A first locking member and a second locking member are movably received in the two slots. The first and second locking members each include a latch to be engaged with a hole of the runner. A button is connected to the base and the second locking member is fixed to the button. A U-shaped member is pivotably connected to the inside of the button and two legs of the U-shaped member can push the first locking member inward to release the runner when opening the umbrella. During the first stage of collapsing the two legs of the U-shaped member are pivoted away from the two distal ends of the first locking member, so that even if the button is pressed, the umbrella does not open.

Abstract: An umbrella structure according to the invention includes a cover, a shaft, a notch, a runner, main ribs and stretchers. The notch is downwardly extended to form an extension section, which is accommodated with the runner and extruded to form an integral elastic protrusion. The protrusion is devised as a fastening button with one end thereof joined with the extension section, and a projecting top portion forming a supporting plane for butting against the runner. When the umbrella is stretched, the supporting plane of the protrusion section is butted against a lower section of the runner to stretch the umbrella.

Abstract: An umbrella structure includes a cover, a shaft, a notch, a runner, main ribs and stretchers. The notch is extended downward to form a fixing portion. The fixing portion has one end disposed with a protruding loop section, and an appropriate position disposed with a fastening orifice for corresponding with the protruding button. The runner is accommodated at the fixing portion, and is capable of up-and-down sliding movements at the fixing portion. When stretching the umbrella, the protruding button at the fastening device is steadily locked at the fastening orifice at the fixing portion to smoothly stretch the umbrella. When collapsing the umbrella, the shaft is stored in the fixing portion to prevent the shaft from damages and deformations by offering the shaft with appropriate protection. Using the aforesaid structure, a drawback as being incapable of securely stretching the umbrella due to a reduced volume of the umbrella is solved.

Abstract: A flat umbrella improvement structure is comprised of a notch and a runner, both are in flat shapes. A variety of main ribs have one ends thereof symmetrically pivoted on both sides of the curved edges of the notch and have the middle portions thereof that are pivoted to the notch on the same side of the notch designed as curved surfaces and protruded in shape, in addition, a variety of stretchers that are correspondently pivoted to the main ribs have the portions thereof connecting to the runner designed as curved protruded shapes as well. As the umbrella is collapsed, the collapsed middle radial heights of the main ribs and of the stretchers are higher than the collapsed radial heights of the rest main ribs and of the corresponding stretchers. Therefore, the umbrella of the invention is able to be collapsed tightly in a flat collapsed shape with minimum umbrella size, thereby enabling said umbrella to be easily carried and stored.

Abstract: This invention presented is a detachable light-emitting device having a head connecting portion and a base integrally formed. The base has a circuit board installed thereon, assembled with a light permeable portion. A switch, a power outlet for holding a battery and luminous bodies on the circuit board and placed inside the light permeable portion. The light permeable portion has a bonnet assembled on the upper portion thereof and over a push-button end of the switch. A push-button portion has the lower portion thereof assembled on a power button, a spring is then assembled between the bonnet and the power button for providing a restorable elastic strain for the push-button portion. The assembly of this invention enables the light-emitting device to be easily attached to and detached from an object, thereby adding light-emitting effect and function to the object.

Abstract: An umbrella can include a handle forming a cavity within the handle, and a holder disposed within the cavity. The holder can have a first position within the cavity and a second position disposed telescopically from the handle. The umbrella may further include a replaceable power supply, a light source, and a set of cutoff switches disposed within the holder. The cutoff switches can be electrically connected to the replaceable power supply and embedded in the holder. What is more, the holder can be pulled telescopically out of the cavity to the second position to connect the light source to the power supply through the release of the cutoff switches and to automatically activate the light source. In addition, the holder can be pushed back into the cavity to the first position, thereby restoring the handle to its original state.

The protrusion is devised as a fastening button with one end thereof joined with the extension section, and a projecting top portion forming a supporting plane for butting against the runner. When the umbrella is stretched, the supporting plane of the protrusion section is reliably butted against a lower section of the runner to smoothly stretch the umbrella. Thus, the aforesaid structure is capable of overcoming a drawback as being incapable of steadily stretching the umbrella due to a reduced volume of the umbrella.

Abstract: The rib assembly for multi-foldable umbrella includes an inner rib, a middle rib, an outer rib and a secondary rib. Wherein, the secondary rib and the front strut are solid shafts and the pivot joint of the secondary rib and the inner rib is not necessitated to be flat in shape. Therefore the supporting strength of the secondary rib and the front strut against bending are increased, and the volume thereof is also effectively reduced for further significantly decreasing the volume of the collapsed umbrella as a whole, thereby bringing better convenience for carrying.
