DESCRIPTION

MULTIPLE POINTED TOOL DESIGNED TO TIGHTEN OR LOOSEN SCREWS OF DIFFERENT SIZES

OBJECT OF THE INVENTION

The present invention relates to a multi-point tool intended to tighten or loosen screws of different sizes. More particularly, the present invention describes a tool where tips of different sizes are adapted to be housed one inside the other, so that each tip can be independently actuated to come out of its housing depending on the size of the screw head. that needs to be tightened or loosened. As a consequence, a compact tool is achieved which itself has a plurality of tips suitable for being used individually, without the need to have a screwdriver for each of the tips.

BACKGROUND OF THE INVENTION

A screwdriver (screwdriver or screwdriver) is a tool used to tighten and loosen screws and other machine elements that require little tightening force and are generally small in diameter.

A multitude of screwdriver configurations are known in the state of the art. For example, there are screwdrivers of the type that comprise a handle and a shank, where the distal end of said shank is adapted to engage different types of tips, both by size and by configuration, for example hexagonal, flat, serrated, star, etc. etc.

However, in this type of screwdriver, the operator must, usually, carry a box where he carries all the bits he may need in his work. This also requires searching the box for the right tip each time it is needed, which can require an iterative process of trial and error, causing a significant loss in operator productivity. Likewise, these tips can be easily lost.

In addition, the user must carry other types of tools, such as scissors or pliers, "cutters" (blades) to, for example, strip cables or flashlights to illuminate works that They do not present natural or artificial light. Consequently, it is usually necessary to carry a bulky toolbox even for simple repair work.

DESCRIPTION OF THE INVENTION

The present invention aims to solve some of the problems mentioned in the state of the art. More specifically, the present invention describes a multi-point tool intended to tighten or loosen screws of different sizes, where said tool comprises:

- a plurality of tips of different sizes intended to be inserted into the head of the screw, where said tips are configured to be housed one inside the other in a distal portion of the tool,

- a plurality of stems housed in a housing within a casing, each stem operatively attached to a tip,

- a plurality of toothed wheels, where each toothed wheel is adapted to mesh with a toothed portion of the stems, so that, when one of the toothed wheels rotates, it linearly moves one of the stems, causing the tip attached to said stem to come out.

In a first preferred embodiment, the tool further comprises an outer wheel coupled to a shaft passing through each of the gear wheels, and a clutch mechanism arranged between the shaft and each of the gear wheels, where said clutch mechanism it is configured to individually engage each toothed wheel with the corresponding toothed portion of each stem.

As a consequence, the operator can select which tip he needs in his work and consequently choose which toothed wheel to engage by means of the clutch mechanism. Subsequently, by turning the outer wheel, the corresponding rod moves linearly, thus pulling out the desired tip.

Preferably, the clutch can be of the electronic type with buttons on the casing so that the user can easily choose which toothed wheel to engage and therefore which point comes out when the outer wheel rotates.

In a second preferred embodiment, the sprockets are only partially housed in the casing, so that a portion of each sprocket protrudes from said casing, thus allowing the operator to directly rotate each of the sprockets from the outside of the casing, without the need for a clutch mechanism.

In another preferred embodiment, each toothed wheel is operatively coupled to a transverse shaft which in turn is connected to a drive wheel arranged externally to the casing. As a consequence, the user must turn one of the drive wheels arranged on the outside of the casing depending on the point that he wishes to remove, without the need for a clutch mechanism.

Preferably, the plurality of tips are hexagonal, serrated, flat, or any type of configuration used to tighten and loosen screws and other equivalent machine elements.

Advantageously, two tools according to any of the above-mentioned embodiments are rotatably attached to a housing part allowing articulated movement between the housing of each tool and the housing part.

In such a way that the housing part comprises a housing for housing each tool which is in turn housed in the casings and said tools can be extracted from the housing part and rotate relative to it.

As a consequence, two multi-point tools can be attached to the housing piece, where each tool can have different point configurations (groove, star, hexagonal, flat, etc.) forming a versatile multi-purpose tool that includes at least two tools rotatably coupled to a housing part.

Likewise, the tool can have an internal housing in the casing or the housing part to house a blade ("cutter").

Preferably, the blade may be adapted to be driven out of the casing or housing for use. For example, by means of a spring, pins or any known mechanical or electronic equivalent mechanism.

Advantageously, the tool also has a rod provided with a proximal end connected to the casing or to the housing part, where said rod at a distal end in turn comprises tweezers intended to hold and/or cut an external object. The casing or the housing part can be provided with external flanges to house the rod externally when it is not being used, and it can be removed and pivot with respect to the casing or the housing part at a single support point operatively connected to the to said housing part or casing when it is necessary to fasten or cut an object or element, such as cables.

Additionally, the tool may be provided with a flashlight operatively disposed at the distal end of the housing, eg, above the tips.

In a preferred embodiment, the flashlight is powered by a battery housed in the casing, and said battery can also be used for the electronic clutch mechanism or for electric actuators that rotate the gear wheels automatically without the need to be rotated by the operator.

Figure 4 shows a second preferred embodiment of the tool (1) without a clutch mechanism (9), in which each toothed wheel (5) is operatively coupled to a transverse shaft (10) which in turn is attached to a wheel drive (11) arranged externally to the casing (4).

In the preferred embodiment of Figure 4, each of the gear wheels (5) are arranged asymmetrically with respect to the longitudinal axis of the tool (1), for reasons of space, so that the drive wheels (11) would be arranged in the outside of the casing (4) side by side. As a consequence, the operator turns the drive wheel (11) which longitudinally moves the tip (2) that he wishes to use.

Referring now to figure 5, a side view of a third preferred embodiment of the present invention is shown, where two tools (1) like those mentioned above, are rotatably attached to a housing part (15) allowing movement articulated between the casing (4) and the housing part (15).

Thus, the housing part (15) comprises a housing to house each tool (1), which are in turn housed in casings (4).

Note that in the preferred embodiment of figure 5, two multi-point tools (1) are coupled in the housing part (15), where each tool (1) can have different point configurations (groove, star, hexagonal, etc.). flat, etc.) forming a versatile multi-use tool comprising at least two tools (1) rotatably coupled to a housing part (15).

Likewise, the housing part (15) can be provided with the blade (14) and the flashlight (13).
