    OBJECT OF THE INVENTION
    The present invention relates to a rotating open key, intended as a tool to loosen and tighten nuts that are inside a bolt with no outlet at both ends and to such depth that with any conventional key, it would not be possible to access. The rotary open key has been designed and realized to solve the problems and inconveniences when carrying out the assembly and disassembly of bolts and nuts that
    15 due to their design and layout, they are limited to the use of a hand tool or open spanner.
    This invention focuses on making it possible to tighten or loosen a nut on its bolt, regardless of the depth to which it is placed, in a faster, easier and safer way.
    20 The key is a tool that acts as a power multiplier, thus facilitating its use and improving the work.
    The swivel open key can be operated by any standard tool
    25 existing in the market appropriate for this both manual and electrical, hydraulic or mechanical. BACKGROUND OF THE INVENTION
    30 Many types of wrenches are known in the market today, for the use of loosening and tightening nuts. But when you have to act on a nut placed deep enough from its end, everything is limited to the use of open fixed wrenches. Conventional fixed open wrenches only allow manual use by entering and exiting the nut and with a limited twist or travel in both directions due to obstacles
    35 can find.

    DESCRIPTION OF THE INVENTION
    5 Rotary open wrench of the invention constitutes a tool for nuts with rotary drive, and has been developed with the aim of adding an important dose of safety, handling and speed in the tightening and loosening of nuts, compared to conventional models. In addition to adding a variable power multiplier depending on the torque and the type of work.
    10 The rotary open key is composed of a hermetic housing formed by two parts inside which a series of components are installed that make its operation possible, highlighting a connecting piece for drive or power input composed of a standard male type mouth with a pinion and rolling areas inside
    15 to transmit the rotation to two other internal axes mounted in parallel and which have a pinion of the same module carved at one of its ends, an endless gear and its corresponding rolling areas.
    These axes rotate in the opposite direction so the endless gear differentiates them being
    20 carved one in the right turn position and the other left turn. These in turn engage with the central piece in charge of housing and transmitting the power and rotation to the different interchangeable mouths of the key. This centerpiece has a pinion two rolling areas and accommodation for placement of key vessels of different sizes. Throughout its length a groove of dimensions and shapes is practiced depending on
    25 of the dimensions of the key.
    The key mouths fit perfectly at the end of the center piece being inserted inside and being interchangeable for different sizes.
    The wrench of the invention is capable of being manually operated by means of an interchangeable tip screwdriver handle, or by means of a manual ratchet wrench, an electric, hydraulic or battery-powered screwdriver.
    The mouths can be exchanged to fit the necessary nut. No need to attend any technical service or workshop, since it does not require special tools, or


    great efforts.
    In addition, it is a tool of small dimensions, and manageable, adaptable to any tool on the market for its operation.
    It should also be noted that it has an interchangeable mouth system making the key more economical and versatile. Since with a single key different measures can be activated.
    10 It has the possibility of placing extensions for difficult accesses or even articulated keys in any posture.
    Once inserted in the bolt and turned the nut there is no possibility that it will come loose and fall, with the consequent risk involved while applying force on it.
    15 To remove it, simply turn the device over the bolt once it comes out of the nut and after its alignment proceed to the extraction.
    Finally, say that the device described is suitable for handling all types of people
    20 and ages, and focused both for the industrial and personal tools, since it can be implemented in the public, since it would fit perfectly as a key for tensioning of bicycle or motorcycle radios at a particular level, as an alternative to those Open keys in the form of grimaces that are supplied in the bicycle houses. 25 DESCRIPTION OF THE DRAWINGS
    To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, it is accompanied as an integral part of said
    30 description, a set of drawings where, for illustrative and non-limiting purposes, the following has been represented:
    Figure 1 shows a representation corresponding to an exploded view of the parts or components that constitute the assembly of a rotating open key made of
    35 according to the object of the present invention.


    Figures 2, 3 and 4.-They show views in plan, elevation and profile of the rotating open key of the invention.
    5 Figure 5.- Shows a representation corresponding to a plan view of the internal set of mechanisms comprising the key of the invention. PREFERRED EMBODIMENT OF THE INVENTION
    As can be seen in the aforementioned figures, the device of the invention is constituted from a housing formed by two complementary halves (1 and 2) fused together once the inner mechanism is assembled, whose function will be exposed later, including also cavities and housings (3), with different configurations and in different areas for the location of the elements that will be described below,
    15 said housing being provided with two axial steps open to the outside to position the power input tool and the suitable vessel to the nut.
    The first element is the drive shaft (4) that incorporates a pinion (5) at one of its ends, while at the opposite end it has a nut or mouth
    20 universal hexagonal (6), according to the requirements of each type of key for its power and dimensions. The pinion (5) meshes with two pinions (15) belonging to two parallel axes (7-7 ’).
    The drive shaft (4), through its pinion (5) gears and spins the shafts
    25 parallel right and left (7-7 ') simultaneously, provided in their central area of their respective carved spindles (8 and 8'), one on the right and one on the left counting both with support areas (9-9 ') for its friction in the turn.
    The axes carrying the spindles (8-8 ’) have, at the opposite end of the sprockets 30 (15), respective supports for mounting and turning the axes themselves.
    On the spindles (8 and 8 ') of the parallel axes (7 and 7') a crown (10) engages which is open longitudinally, presenting a housing (12) inside its upper part for the housing of interchangeable vessels ( 13) and support areas and
    35 friction


    The central part (11) is affected by a longitudinal opening (14) provided to be able to position on the bolt or stud related to the vessel (13) and the nut (6) to be operated.
    That is, the rotating open key comes into direct contact with the nut (16) and the bolt or stud, allowing the longitudinal opening (14) made in the central part (11) to access the nuts themselves that are mounted on the bolt closed at the ends and without the possibility of accessing through space with another type of current key in the
    10 market
    From this structure, at the end of the central part (11) of the crown (10) it is possible to place different vessels with a single rotating open key at one of its ends, the other being only as a guide.
    15 Finally, to say that the materials in which both the halves that make up the housing, such as the shafts and their pinions are constituted can be any, always depending on the necessary dimensions and requirements of each case.
    20 Regarding the advantages and benefits offered by the described device, the following may be mentioned:
    - It has the possibility of directly accessing a nut mounted on a bolt without access by the ends or without the possibility of movements to both
    25 sides, allowing to turn the nut in both directions, either manually or with any screwdriver type accessory of replaceable mouths or by means of its corresponding accessory, adapting a mechanical, hydraulic or pneumatic tool, since turning the central axis of the device is spins the nut
    - It is possible to act on nuts with a difficult level of access.
    - The pinions and gear system that are part of the device determine a torque multiplier, which can be modified or adapted based on the required use.


    - It is accessible and very practical at a particular or industrial level.
    - It allows the possibility of its use in several dimensions of nuts with a single 5 key and different mouths.
    - It is gained in security, since the possibility that while making force for tightening or loosening is avoided, the key is prevented from being released with the consequent risk of accident.
    - The axes carrying the gears can be mounted on bearings or bushings to absorb large revolutions and continuous work
    This type of wrench offers the possibility of incorporating a torque wrench in order to achieve a suitable torque on each occasion.
