Definitions

  • the present invention relates to a device for storing and exchanging interchangeable tool bits, such as screwdriver or drill bits, preferably for cordless screwdrivers or cordless drills, equipped with a magnetic adapter.
  • interchangeable tool bits such as screwdriver or drill bits, preferably for cordless screwdrivers or cordless drills, equipped with a magnetic adapter.
  • the known storage devices for bits are designed solely for storing bits. To change a bit, the current bit attached to the tool (screwdriver) must be manually removed from the adapter and placed into the storage device. Then, a new bit is selected from the storage device and inserted into the adapter by hand.
  • Another known bits magazine (EP2301724, published on 30.03.2011) features a bit holder that receives the bit. The bit is guided into and out of the bit holder along one trajectory but is locked in place along another trajectory.
  • the bit holder has a flexible and elastic lock or stopper.
  • the magazine's parts are produced by extrusion or injection molding.
  • bits magazine (EE P202000008, published on 15.12.2021) that contains a housing with multiple bit holders where bits are inserted. It features a bit grabbing button with a conical surface designed to operate the bit gripping mechanism. Inside the magazine housing is a bit stopper with a pusher for the stopper, a bit gripping mechanism, and a magnetic adapter for the bit. The bit holders are arranged in a circular pattern on the housing. The diameter of the lower part of the housing is larger than that of the upper part.
  • the magnetic adapter with the bit is inserted into an empty holder.
  • the bit is gripped by the mechanism.
  • the magnetic adapter is pulled out of the holder, the bit remains in place.
  • an empty magnetic adapter is inserted into the required holder, and the bit is picked up by the magnet as the adapter is withdrawn.
  • the aim of the presented invention is to provide a bits magazine for storing tool bits, such as screwdriver bits, free from the drawbacks described above.
  • the bits magazine for holding interchangeable tool bits for a tool, includes bit holders inside the magazine housing for storing bits and inserting and removing them from the bit holders using a magnetic adapter.
  • the bit holders contain a bit stopper for retaining the bit inside the holder and a pusher at the bottom of the holder, a gripping mechanism for gripping the bit, and a button to operate the gripping mechanism.
  • At least three bit holders are arranged side by side in a straight line, and stationary and movable jaws of the gripping mechanism are placed crosswise through the bit holders inside the housing, with the stationary and movable jaws forming a variable-sized opening within each bit holder. Pressing the button connected to the movable jaw engages the bit, and releasing the button disengages it.
  • the bit holder is adapted to hold hexagonal bits.
  • the housing is equipped with a connecting element for connecting together at least two bit magazines.
  • the connecting element may be detachable or integrated with the gripping button.
  • bit holders are arranged in at least two rows of three.
  • the bits magazine includes labeling means on the housing near the bit holders.
  • the bit magazine designed to store tool bits and to enable quick and convenient insertion and removal using a magnetic adapter on a tool, such as a drill or screwdriver, preferably a cordless screwdriver, eliminates the need for manual removal or insertion of bits into the tool adapter.
  • the bits magazine features bit holders inside the housing for storing bits and inserting and removing them using a magnetic adapter.
  • the bit holders contain a stopper for securing the bit in place and a pusher at the bottom, with the stopper's pusher and the bit pusher being in different positions (compressed or free) depending on use.
  • the bit holders may have labeling means.
  • bit magazine and the gripping mechanism/button ensures that it is easy to hold while pressing the gripping button with one hand, allowing for quick and simple bit changes.

  • Figure 2 A view of the gripping set of the bit magazine.
  • Figure 3 A partially cutaway front view of the bit magazine.
  • the bit magazine for a tool is a device for inserting, storing, and removing bits, intended for use with interchangeable bits equipped with a magnetic adapter, such as a screwdriver, preferably a cordless screwdriver.
  • the tool's bit magazine comprises a housing 1, comprising two halves 1A and IB, at least two bit holders 2 inside the housing, and a gripping button 3 connected to a movable jaw 5 of a pair of jaws 4, 5 inside the housing.
  • the bit holders 2 are equipped with stoppers 6 to hold the bit 12 in place.
  • the stoppers 6 allow bits to be freely inserted into the holders but prevent them from falling out.
  • the stoppers 6 move into slots 6.1 in the housing, which include a spring recess 6.3 for the stopper's spring 6.4.
  • a stopper limiter 6.5 The movement of the stopper towards the bit holder is limited by a stopper limiter 6.5.
  • a notch 6.6 on the back of the stopper catches on the limiter, preventing movement in an empty holder.
  • a pusher 7 is located at the bottom of the bit holder 2, equipped with a spring 8. The spring is either compressed or in a free position depending on whether a bit 11 is present in the holder.
  • five bit holders 2 are arranged in a single row.
  • the design of the gripping pair 4, 5 depends on the arrangement of the bit holders.
  • the stationary jaw of the gripping pair 4 is fixed to one half of the housing.
  • the movable jaw is connected to the gripping button 3, and a spring 9 is placed between the button 3 and the housing 1.
  • the bit magazine is designed to work with a tool's magnetic adapter 12 and bit 11, where the magnetic adapter 12 holds the bit 11.
  • the magnetic adapter 12 with the bit 11 is placed into an empty bit holder 2.
  • the bit stopper 6 moves into its slot 6.1, compressing the stopper spring 6.4.
  • the magnetic adapter 12 reaches the bottom of the holder, the bit's hexagonal portion is within the working area of the gripping mechanism 4, 5.
  • the gripping button 3 By pressing the gripping button 3, the movable jaw presses the bit 11 against the holder wall, allowing the magnetic adapter 12 to be removed.
  • the pusher spring 8 pushes the bit's hexagonal portion out of the working area of the gripping mechanism 4, 5, and the bit 11 remains in the holder 2.
  • the stopper spring 6.4 also returns to its free position, preventing the bit from falling out.
  • the magnetic adapter 12 is inserted into the holder 2, displacing the stopper 6.
  • the hexagonal portion of the bit 11 is inserted into the magnetic adapter 12 and secured by the magnet.
  • the bit 11 is then withdrawn along with the magnetic adapter 12. Bits in other holders remain locked by the stopper 6, so only the bit in the holder with the magnetic adapter 12 can be retrieved.
