  • Interchangeable single-sided blade retention devices that may be used as a conventional screwdriver handle but can also be used as a screwdriver with a ratchet mechanism when rotated 90 degrees, is disclosed in the patent application US20120222524A1.
  • the system enhances existing inventions by using double-sided blades, single-sided blades, or other accessories.
  • the hole arrangement at the end of the hexagonally shaped interchangeable blade enables to use the system in all the tools described above, i.e., not only with single-sided blades, but also with double-sided blades, and with single-sided blades with a certain insulated blade and different screw-driving profiles, which was not possible with the prior art solutions.

  • Figures 1 and 2 show a basic illustration of the interchangeable blade and handle system with the system according to the invention.
  • Figures 3 and 4 illustrate the individual components of the system according to the invention.
  • the handle 1 is provided with a hexagonal opening 8, into which the retaining device 2 of hexagonal shape with an opening 7 is installed.
  • the retaining device 2 is provided with a hole 6 at the end thereof into which a spring element 5 is installed.
  • Figures 5, 5a and 6 show a basic cross-sectional view of the assembled system with a double-sided interchangeable hexagonal blade 3, placed in a hexagonal retaining device 2 and a handle 1, whereby the blade 3 is provided with a profile 3a for screwing PH2 (Phillips-cross profile 2) on one side thereof and a profile 3b for screwing PHI (Phillips-cross profile 1) on the opposite side.
  • the blade 3 has two holes 4 at each end, wherein the hole 4, in cooperation with the spring element 5, allows the blade 3 to be held in an axial direction relative to the handle 1. This enables the blade 3 to be fixed in the handle 1 by the spring element 5, said spring element 5 being installed in the retaining device 2 and lying in the hole 4, as shown in Figure 6.
  • Figures 7, 8 and 8a show a cross-section of the assembled system with a doublesided interchangeable blade.
  • Figure 7 illustrates how the hexagonal blade 3 most efficiently transfers torque or other operations from handle 1 to blade 3, as the largest part of the surface area is overlapped and enables stable handling or screwing.
  • FIG. 9 A cross-section of the handle 1 with the installed retaining device 2 and the spring element 5 is shown in Figures 9 and 10, while Figures 11, 12 and 13 show the retaining device 2 with the installed spring element 5.
  • the present invention provides the use of the blades on both sides, enabling twice as many profiles compared to the single-sided version, therefore enabling more efficient work.
  • the blades with a handle are more space-efficient, which offers economic benefits, as it also reduces material usage.
  • single-sided blades are used in the same system, which allows to increase the functionality and usability of the system for blades with profiles that, due to their oversized dimensions (e.g., flat blade 1 la with 1.2X8 ferrule in Figure 17, or other special larger ferrules), do not fit into the opening of the retaining device.
  • This enables insertion of various tools into the system, such as awl, chisel, magnetic bit, etc., as shown in Figures 18, 19 and 20.
  • the blade with a magnetic holder 13a (C6,3 or *4") may be used and allows the user to use the holder with holders of various profiles (C6,3 or *4") for shorter and quicker jobs, as is illustrated in Figure 21. Since the system according to the invention may be used with larger profiles or tools, this increases the functionality and universality of the system.
  • the system may be very narrow/compressed, it may also be inserted into other systems that provide the user with an additional function, i.e. it is not only useful for holding single-sided or double-sided blades of screwdrivers and similar tools, but it may be used on handles where the torque may be pre-set, and prevents further screw-driving in the rotational direction when the torque is set and reached, which means that no further torque is generated.
  • a handle 17 is shown in Figures 28, 29 and 30, where the knob 19 may be used to set the desired or specified (by the element to be screwed, since in certain elements the fastening torques are precisely defined) torque which holds the blade 7 to the spring element 5 in the retaining device 2.
  • the system may be used with all the above-mentioned types of blades, i.e., double-sided blades made of hexagonal material, standard singlesided blades made of hexagonal material, and insulated blades suitable for live work.
  • the handles have a hexagonal opening into which a system is inserted, that is pre-assembled with a spring that expands when the blade is inserted into the system until it locks when it moves on the recess.

Abstract

L'invention concerne un système pour retenir et maintenir une lame interchangeable dans le manche d'un outil multifonctionnel, la lame interchangeable (3) étant fixée contre une chute dans la direction axiale par une combinaison d'un élément ressort (5) installé dans un dispositif de retenue (2) dans le manche (1) et d'un trou (4) au début de la lame interchangeable (3), et dans la direction de rotation par la forme hexagonale de la lame (3) et du dispositif de retenue (2). Le système est applicable à une lame interchangeable multifonctionnelle ayant une extrémité fonctionnelle simple face ou double face (soit pour le vissage, soit d'autres tâches fonctionnelles) et à un type variable d'un manche avec une ouverture dans laquelle le système peut être mis en œuvre, ayant une fonction supplémentaire spécifique à effectuer, par exemple, un encliquetage.
