Description

Field of the invention

[0001] This invention relates the building sector and more specifically that related to the assembly of scaffolding and concerns a tool holder accessory, to be inserted slidably into a belt, on which the pincer and the ratchet spanner with a double bush specifically designed for scaffolding can be inserted simultaneously for the connection of the pipes through orthogonal joints.

Background of the invention

[0002] At the state of the art, it is known that in the sector of scaffolding assembly there are various tool holder accessories that a scaffold fitter can insert slidably into a belt, inside which he can insert different tools.

[0003] It is also known that a scaffolding assembler - or scaffold fitter - is that working figure that assembles, disassembles and transforms different types of scaffolding, allowing work to be carried out safely in a construction site. Among the tools commonly used by a scaffolding assembler are the hammer, the pincer and the ratchet spanner with a double bush specifically designed for the connection of pipes through orthogonal joints.

[0004] According to the safety regulations at work, the ratchet spanner with a double bush should be placed in a secure housing on the fitter's belt and have a lanyard that, if necessary, can be hooked to the spanner to prevent it from falling.

[0005] The work tools are usually inserted individually into iron rings or leather cases which are then slidably inserted by means of loops on a belt that the scaffolding assembler wears on his waist or on his hips.

[0006] Still in the field of tool holder accessories, an evolution in the use of rings has been to replace them with leather bags or other materials with multiple holders, each specific to accommodate a tool or a tool necessary at work. The following are the disadvantages related in using the tool holder rings:

• each ring is used to house each tool individually, or to each tool holder ring there is a loop passing through the belt;
• for the above reason, since into the belt must be inserted more than one bushing, said amount of loops entails a greater encumbrance at the waist of the scaffold fitter;
• the rings are not safe as it could happen that, when the fitter bends the knees, the spanner, striking on the scaffolding, if it is not equipped with the lanyard, could exit the ring and hence fall accidentally downwards.

[0007] The tool holder bags, instead, have the disadvantage that, for a scaffolding assembler, they are cumbersome not only to be worn on the waist, but also operationally during work since, when the said fitter must bend, to perform the movement easily he is forced to move the bag forward or backward with respect to the hip, and then put it back in the usual position when standing up.

Disclosure of the invention

[0008] Object of this invention is to provide a tool holder accessory to be slidably inserted into a belt and which is capable of simultaneously accommodating a pincer and a ratchet spanner with a double bush occupying the space of a single loop on the belt.

[0009] Another object of this invention is to provide a tool holder accessory which, while simultaneously housing two tools, is less cumbersome for the user with respect to the tool holder accessories known to the state of the art.

[0010] Another object of this invention is to provide a tool holder accessory which does not need to be moved forward or backward on the user's hip in case of bending movements of the legs.

[0011] Another object of this invention is to provide a tool holder accessory which, in the event of bending movements of the legs, remains in adherence to the user's limb without turning outwards.

[0012] Another object of this invention is to provide a tool holder accessory which is able to prevent the accidental fall of the pincer and the ratchet spanner in the event of bending movements of the user's legs.

[0013] A further object of this invention is to provide a tool holder accessory which does not require a lanyard to be hooked to the ratchet spanner to prevent accidental fall.

[0014] Last but not least, object of this invention is to provide a tool holder accessory which facilitates the user both when inserting and gripping the pincer and the spanner.

[0015] These and other objects are achieved with this invention which relates to a tool holder accessory for the scaffolding assemblers' belts.

[0016] Further characteristics and advantages of the invention will become clearer from the description of a preferred but not exclusive embodiment of the tool holder accessory for the belts of the scaffolding assemblers object of this patent application, illustrated by way of non-limiting example, in the underlying drawing units:

Detailed description of the invention

[0017] According to a preferred - but not limiting - embodiment, this invention relates to a tool holder accessory (1) to be inserted slidably by means of a loop (2) on a known belt (3).

[0018] Said tool holder accessory (1), compared to the accessories known to the state of the art is less cumbersome and safer, in that it:

• houses simultaneously a pincer (5) and a spanner (9) occupying the space of a single loop (2) on a belt (3);
• allows the user to carry out all the movements necessary for his work, including bending the knees, without having to move it forward or backward on the hip and then reposition it;
• remains always in adherence to the user's limb, without rotating outwards in case of bending movements of the legs;
• avoids the accidental fall of the pincer (5) and the spanner (9) in the event of bending movements of the user's legs.

[0019] Said tool holder accessory (1) consists of:

• a tubular (4) closed at its lower end and:
  • inclined with respect to the user's leg by about 4° in such a way that it accompanies the conformation of the limb;
  • welded to a loop (2) which is curved in order to follow the anatomy of the user's pelvis;
  • wherein it is possible, by using one of the two handles, to insert a known pincer (5);
  • equipped with an inlet section (6) capable of facilitating insertion and gripping by the user of said pincer (5);
  • equipped along its section with a flattened part (7) capable of preventing rotation of the pincer (5) once inserted into the tubular (4);
• a tubular (8) closed at its lower end and:
  • inclined with respect to the user's leg by about 9° in such a way that it accompanies the conformation of the limb;
  • welded to the tubular (4) at a point (A) corresponding to the starting point of the section of said tubular (4) and at a point (B) corresponding to the end point of the section of said tubular (4);
  • wherein it is possible to insert a known ratchet spanner with a double bush (9).
  • equipped with an input section (10) capable of facilitating insertion and gripping by the user of the spanner (9).

[0020] The tubular (4) as well as the tubular (8) are inclined, with respect to the user's leg, by about 4° and 9° respectively, so that, in case of bending movements of the legs, the tool holder accessory (1) remains always in adherence to the limb without rotating outwards and run the risk of getting stuck in the scaffolding.

[0021] As far as the pincer (5) is concerned, only one of its two handles can be inserted in the tubular (4) and, in order to further benefit from the use of the tool holder accessory (1), the handle that remains outside must be directed by the belt side (3) wherein a loop (11) with an iron ring for insertion of a hammer (12) (see Figure 5). In this way the pincer (5) handle which remains outside is blocked by the presence of the hammer (12) and this avoids the risk that it may open, entailing an opening of the jaws and the consequent bruising of the user's skin when the pincer (5) is extracted.

[0022] The flattened part (7), present along the section of the tubular (4), has the task of preventing rotation of the pincer (5) handle in the tubular (4) thereof, ensuring its stability.

[0023] Moreover, Figures 2-3-4 show that the pincer (5) as well as the spanner (9) remain protruding with respect to the respective tubulars (4, 8), and said characteristic serves to facilitate gripping without the user being forced to look first where to put his hands.

[0024] The tubular (8) with respect to the loop (2) and consequently with respect to the tubular (4) is in a lower position and this prevents the user from having to look in the direction of the accessory (1) before choosing which tool to take, allowing him to easily memorise the position and hence make the movement automatically.

[0025] Furthermore, both tubulars (4, 8) are provided with respective inlet sections (6, 10) which serve to facilitate inserting both tools (5, 9) since, once said sections (6, 10) have been overcome, the handles of said tools, striking against the rear part of the section of the respective tubulars (4, 8), find without fail the insertion seat without the user having to look in the direction of the accessory (1) before inserting them.

[0026] The materials and dimensions of the invention as described above, illustrated in the accompanying drawings and hereinafter claimed, may be any according to requirements. Furthermore, all the details can be replaced with any others technically equivalent, without thereby abandoning the protective scope of the present patent application.
