TECHNICAL FIELD

The invention relates to the field of screw drivers. More particularly, the invention relates to a reduced screw driver and to a head.

BACKGROUND

Fig. 1 depicts a prior art wrench, and the problem regarding the use thereof. A prior art wrench 72 is shown embracing a prior art tip

18A, being a screwdriver head element, for rotating a screw head 16.

However, the overall thickness 64A of prior art wrench 72 together with prior art tip 18A is too large. Fig. 1 shows a case that the distance between a wall 12 and the hung element 14, between which screw head 16 is disposed, is sufficiently large for inserting tip 18A only, but is too small for inserting prior art wrench 72.

There is a long felt need to provide a solution to the above-mentioned and other problems of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be understood from the following detailed description of embodiments of the invention, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features are not described in detail.

The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting. Fig. 2 is a perspective view of a screw driver according to one embodiment of the invention.

A screw driver 10A according to one embodiment of the invention, includes a wrench handle 46; a niche 36 disposed at the end of wrench handle 46; and a tip 18B, being housed within niche 36, such that wrench handle 46, niche 36, and tip 18B occupy a shared thickness 64B, being the overall thickness.

Fig. 3 is a side view of the screw driver of Fig. 2 at operation. Tip 18B includes a screwdriver head or a nut-driver head of any available type, and thus is configured and shaped complementary to a screw head 16, for being inserted thereinto, or for embracing a nut (not shown).

Thus, in addition to wrench handle 46, to niche 36, and to tip 18B, screw head 16 as well occupies said shared thickness 64B.

Fig. 4 is a schematic side view of the screw driver of Fig. 1 and that it solves the problem of Fig. 1.

Unlike Fig. 1, since here wrench handle 46, niche 36, and tip 18B, all of screw driver 10A, and as well screw head 16, all occupy said shared thickness 64B, screw driver 10A is insertable between wall 12 and hung element 14.

Fig. 5 is a perspective view of a screwdriver head according to one embodiment of the invention, being similar to the head of the screw driver of Fig. l; and a handle for turning the screwdriver head.

A screw driver head 10B according to one embodiment of the invention, includes an engaging head 60A, for engaging thereof to a complementary engaging head 60B of a wrench 20; a niche 36 being a niche in engaging head 60A; and tip 18B, being housed within niche 36, such that engaging head 60A, niche 36, tip 18B, and engaging head 60B of wrench 20 occupy the shared thickness 64B.

Screw driver head 10B may further include a peripheral extension 26, extending from engaging head 60A, for pressing thereof to the direction of arrow 66 towards the wall, by engaging head 60B of wrench 20. Fig. 6 is a side schematic view of the screwdriver head of

Fig. 5.

Screw driver head 10B may further include an attaching element 22, for attaching screw driver head 10B to engaging head 60B of wrench 20. Attaching element 22 may constitute a springy pressing element, for pressing thereof towards engaging head 60B of wrench 20 (of Fig. 5). According to another embodiment, attaching element 22 may constitute a magnet. Fig. 7 depicts the screw driver head of Fig. 5, joining the screw head of Fig. 1, and having a location adjusting mechanism.

Screw driver head 10B may further include a thread 30, extending from a user-operable handle 28, for sliding tip 18B in relation to niche 36. Tip 18B is not rotatable in relation to niche 36.

Thus, in one aspect, the invention is directed to a screw driver head (10B), including:

- a main engaging head (60A), for engaging thereof to a complementary engaging head (60B) of a wrench (20);

- a niche (36), including a niche in the main engaging head (60A); and

- a tip (18B) being shaped complementary to a screw head (16) for rotating thereof, the tip (18B) being housed within the niche (36), thereby the main engaging head (60A), the complementary engaging head (60B) of the wrench (20), the niche (36), and the tip (18B) all occupy a shared thickness (64B), thereby diminishing it.

The screw driver head (10B) may further include:

- a peripheral extension (26), extending from the engaging head (60A), for pressing thereof, by the engaging head (60B) of the wrench (20), towards (66) the wall (12), for attaching the screw head (16) thereto.

The screw driver head (10B) may further include:

- a pressing element (22), for pressing thereof by the engaging head (60B) of the wrench (20).

The screw driver head (10B) may further include:

- a thread (30), extending from a user-operable handle (28), for allowing sliding the tip (18B) in relation to the niche (36).

In another aspect, the invention is directed to a screw driver (10A), including:

- a wrench handle (46);

- a niche (36) disposed at an end of the wrench handle (46); and

- a tip (18B) being shaped complementary to a screw head (16) for rotating thereof, the tip (18B) being housed within the niche (36), thereby the wrench handle (46), the niche (36), and the tip (18B) occupy a shared thickness (64B),

thereby reducing the overall thickness of the wrench handle (46) with that of the tip (18B).
