Abstract
A storage device includes at least one cartridge defining a cavity for receiving at least one storage item. A receiver defines at least one cell for receiving the at least one cartridge, and a passageway extends longitudinally along the center of the receiver to an opening defined in an external surface of the receiver. Magnets are secured to the receiver and at least one cartridge for magnetically biasing the at least one cartridge in a first position in the at least one cell wherein the cavity is not aligned with the passageway, and in a second position in the at least one cell wherein the cavity is aligned with the passageway. In one application, the storage device is adapted for storing bits in a multi-bit screwdriver.
Claims12
A storage device comprising:
- one or more cartridges, each cartridge defining a respective cavity of one or more cavities for receiving a respective storage item of one or more storage items;
- one or more cartridge magnets, wherein a respective cartridge magnet of the one or more cartridge magnets is secured to the bottom of each respective cartridge of the one or more cartridges;
- one or more button magnets, each button magnet being embedded in a lower portion of a respective cartridge, wherein each button magnet has a magnetic polarity which is opposite the polarity of a respective cartridge magnet;
- a receiver defining one or more radially extending cells for receiving the one or more cartridges, and defining a passageway extending longitudinally along the center of the receiver to an opening defined in an external surface of the receiver;
- one or more receiver first magnets embedded in each cell of the receiver;
- one or more receiver second magnets embedded in each cell of the receiver, the one or more first and second magnets having opposite polarities;
- and
- wherein, within each respective cell, a respective one of the one or more receiver first magnets is positioned with respect to a corresponding one of the one or more cartridge magnets, and a respective one of the one or more receiver second magnets is positioned with respect to a corresponding one of the one or more button magnets, for biasing the one or more cartridges in a first position in the respective cell wherein the cavity is not aligned with the passageway, or in a second position in the respective cell wherein the cavity is aligned with the passageway.
5 more elements
A multi-bit screwdriver comprising:
- one or more bits, each of the one or more bits defining a base end and a head end, the base end defining at least one surface extending longitudinally along the base end, the head end being configured for engaging a fastener;
- a handle defining a passageway extending longitudinally along the center of the handle, the handle further defining one or more rows of one or more cells extending radially from the passageway, each cell being configured for holding a respective cartridge configured for holding a respective one of the one or more bits, each cartridge being further configured for radially sliding toward the passageway until the bit held by the cartridge is aligned with the passageway, each of the one or more bits being sized for sliding along the passageway;
- a tubular shaft extending from the handle, the shaft defining a proximate end proximate to the handle and a distal end distal from the handle, the shaft including a barrel and a sleeve slidably fitted about the barrel, the barrel defining a hollow cylindrical space aligned with the passageway of the handle for facilitating sliding of a bit along the hollow cylindrical space of the barrel, the barrel including at least one land extending longitudinally along the interior of the cylindrical space, the at least one land corresponding to the at least one flat surface of the base end of a bit, the land being narrow in cross-section at the proximate end of the shaft and continually expanding in breadth toward the distal end of the shaft;
- at least one cut-out defined at the distal end of the barrel;
- at least one leaf spring defining a first end and a second end, the first end being attached to the barrel;
- at least one locking block attached to the second end of the leaf spring, the at least one locking block being aligned for insertion in the at least one cut-out;
- a coil spring positioned between the handle and the sleeve for biasing the sleeve in a distal position away from the handle,
- wherein, when the sleeve is in the distal position and a bit is positioned in the distal end of the shaft, the leaf spring biases the at least one locking block into the at least one cutout against the base end of the bit to lock the bit in the distal end of the barrel, and
- wherein, when the sleeve is moved toward the handle, away from the distal position, and a bit is positioned in the distal end of the shaft, the leaf spring allows the at least one locking block to moves away from the at least one cutout and away from the base end of the bit.
