摘要:
An umbrella is formed of an elongated shaft having a first end and an opposite second end and a runner slidably disposed about the elongated shaft. The umbrella includes a rib assembly including a plurality of ribs that are attached to the runner by a plurality of struts that move between open and closed positions. In accordance with the present invention, the elongated shaft has a cross-sectional shape defined by a plurality of curved sections and a plurality of planar sections interspersed between the plurality of curved sections for providing increased torsional strength to the elongated shaft. At least one of the ribs can have a cross-sectional shape defined by a plurality of curved sections and a plurality of planar sections interspersed between the plurality of curved sections for providing increased torsional strength to the at least one rib.

The invention relates to a pole comprising a pole handle and a pole tip, and having at least two tube portions (7, 8) located therebetween, which in an assembled state of the pole are connected to one another by means of insertion connections aligned along a longitudinal pole axis (A). At least one of the plug connections is thereby realized on a second tube portion (8) by way of a form-fit and/or force-fit locking device (5), wherein the second tube portion has a smaller or nearly the same outer diameter as the inner diameter of a first tube portion (7), and which can be inserted into the first tube portion, and which can be fixed in the relative axial position by means of the form-fit locking device. On at least one of the plug connections, a tubular sleeve (6) having a clamping element (9) in a receiving groove (11) is arranged between the tubular sleeve and the lower end of the first tubular portion.

Es handelt sich bei dieser Patentanmeldung um ein Exzentersystem, das aufgrund unterschiedlicher Reibeigenschaften in der Exzentereinheit eine selbstständige Festhaltung bei der Drehbewegung auslöst und damit über die Exzentergeometrie die Klemmung erfolgt. in den Ausführungen, Allgemeiner Stand der Technik, Funktionsbeschreibung sowie in den Patentansprüchen ist diese neue Erfindung genau beschrieben. In der Zeichnung Fig 1 ist der technische Aufbau genau beschrieben. Die Zeichnung Fig. 1 dient der Veröffentlichung.
摘要:
The present invention relates to an electronic walking cane for the visually impaired which is adapted with an RFID reader to wirelessly detect RFID tags which are positioned as guides along footpaths with Braille blocks having embedded RFID tags. The present electronic walking cane comprises: a handle which is in the shape of a hollow tube within which a circuit board is installed; a plurality of connectors each having a tapering, hollow tubular structure which are sequentially mounted into each other such that the lower end of one connector is inserted into the upper end of the next connector; a coiled cable, consisting of a plurality of coated wires, with one end connected to said handle and the other end connected to the tip of the lowest of said plurality of connectors; an elastic member for preventing the twisting of said coiled cable, is inserted into the medial section of said coiled cable, with one end connected to said handle and the other end connected to the tip of the lowest of said plurality of connectors; a first and a second fastener which respectively fasten said handle to each of said plurality of connectors, and said coiled cable to said elastic member; and an insulating material having a cylindrical structure installed onto the inner surface of said plurality of connectors, which reduces noises which occur when said elastic member, said coiled cable and said plurality of connectors rub against each other with movement of said walking cane.
