    "Addition to patent P201530051 Lifting jack device consisting of threaded tubes and reversible ratchet"
    SECTOR OF THE TECHNIQUE
    Currently the car jacks are of parallelogram type formed by 4 arms joined together by bases and pins and by means of a threaded spindle and a nut by means of which it is raised or lowered to perform the lifting operation of a vehicle.
    Patent No. CS8904826 is one of the many models of this type of cat. Other types of cats are those denominated in Y similar to No. US6068239. They are somewhat simpler since they usually use 2 or 3 arms connected to each other and by means of a threaded spindle the vehicle is raised or lowered in the same way. These types of cats are very different from those described in the present invention.
    There are other types of so-called bottle cats that are more similar to the one presented here, but that differ considerably, since they are only applicable in cars that are very high from the chassis to the ground (pick-ups), because they have a cat height ratio - Elevation of 2 to 3 maximum, not being applicable in most of the current vehicles.
    BACKGROUND OF THE TECHNIQUE
    The present invention corresponds to the patent application P201530051 dated January 16, 2015, and to the application for patent addition dated November 29, 2015 to which different inventions are added:
    On the one hand, the arrangement of the tubes is inverse to that of the previous application, since the tube with more diameter is in the lower part so that when it rises it is in the form of a pyramid, giving a visual feeling of greater security. A new invention is added when designing a turning system by means of gears that decreases the turning effort to lift the load, since the gear ratio can be 1: 2, reducing the driving effort by half. The set of spinning bearings is also passed to the lower part of the cat, thus reducing the height of the collected cat. A new invention is added when designing a cat positioning system to remain straight at the time of placement, by means of a plate spring, without almost increasing the height of the cat and which also allows the assembly to rotate on the base of support, so that the cat adapts in the ascent and descent to the angle of the vehicle, and thus we minimize the buckling efforts of the cat.
    In the state of the known art, those having some similarity are No. ES2203779, Nos. ES 0176859, ES0333321, ES0228272, US1751738. The cat designed in the present invention differs considerably from those listed above since these do not meet the requirements currently required of a cat for use in utility vehicles, since due to the low height of current cars, these designs cannot be placed under of the car and give the lifting stroke that is currently needed, to release the wheel to change, due to the long stroke of the shock absorbers and the low chassis height of current cars. All these cats usually have a lifting capacity more or less twice the minimum height of the cat, the minimum height of the cat is usually around 180 mm and the maximum elevation above 350 mm so they are not applicable more than for vehicles all terrain, or pick ups.
    The jack of the present invention in a typical design has a minimum collected height of 75 mm and can lift a vehicle to 360 mm or more.
    On the other hand, current bottle cats are expensive designs to produce and of greater weight than current ones (over 4 kg), which is another added problem due to the current trend of the automobile market to reduce the weight of vehicles to improve Consumption and a constant decrease in the purchase price of components, the cat of the present invention is around 1.2 kg, with which a very important weight reduction is achieved, even on parallelogram cats (usually weighing over 1, 8 kgr).
    EXHIBITION OF THE INVENTION
    In order to achieve the objectives discussed above: Reduction of cat weight compared to those currently used. Decreased volume occupied in the vehicle when stored. No increase in manufacturing cost, to be able to displace existing ones in use. Very high lifting capacity in relation to the minimum height of the jack, to be able to be placed in cars with very low chassis and to be able to make a lifting race that is more than 6 or 7 times the minimum length of the cat according to the needs of the vehicle. Stability of the jack in the elevation to minimize safety problems in use. Lower energy consumption in manufacturing than in current processes to minimize environmental impact.
    The present invention is composed of the following elements:
    A base (1), which is a quasi-rectangular stamped piece, has a spherical part in the center to allow the angular rotation of the cat over said area when lifting. This base (1) has live edges at the bottom to make it difficult to turn the base. Likewise, the sheet is corrugated to give more resistance to this element with the minimum material consumption. This base is removed by stamping 2 anti-rotation stops gear set (1a) that make stops of rotation of the gear set. This set of gears is placed between the two anti-rotation stops gear set (1a) and turning the gears prevents their radial rotation, forcing the tubes to rotate.
    On this Base (1) a flat plate spring (2) is placed that keeps the entire jack assembly straight at the time of placing it to lift the load, being slightly separated from the Base (1). The whole cat assembly is kept straight by the action of the flat plate spring (2) when the jack lifts the load, rotates a few degrees to adapt to the inclination of the vehicle, this is achieved by folding the flat plate spring (2) and rotating The lower bearing Support (3) on the spherical part of the Base (1).
    On this plate the lower bearing Support (3) is supported, which also has a spherical shape with the same radius as the Base (1) on which it rests when it is exerting force and on which it can rotate to adapt to the changing angle to the Raise or lower the vehicle.
    On the lower bearing support (3), which is a piece of stamped steel and also carries a heat treatment to prevent wear, which can be cemented or carbonized, an axial bearing (4) is placed that facilitates the rotation of the whole assembly of tubes transmitting the minimum effort to both the Base (1) and the vehicle anti-rotation support (22)
    On the axial bearing (4), the upper bearing support (5) is supported, which is also preferably made of stamped steel, and also has a cementing or carbonate treatment, to facilitate the sliding of the axial bearing (4) with the least friction and wear possible.
    The upper bearing support (5) is welded to the internally threaded tube (13) or tightly bonded by crimp, rolled (figure 7), riveted or other system that strongly binds them both.
    The Moyú of subjection (6) is mounted to pressure on the Support upper bearing
    (5) And it has a radius equal to the lower radius of the Base (1) so that when raising the weight, the flat plate spring (2) decreases due to the action of this weight until supporting the radius of the lower bearing support (3) on the radius of the base (1), the radius of the clamping moyú (6) being free, facilitating the maneuver of rotation of the jack assembly to adapt to the angle requested by the vehicle.
    The tubes (14), (15), (16), (17) and (18) are externally threaded throughout their length.
    Inside they are threaded between 10 and 14 millimeters, the rest is machined to allow the passage of the tube that is introduced through its interior, but leaving a minimum clearance to avoid pancakes of the whole. These tubes have at the bottom of a groove (20), where a metal ring is introduced that prevents the tube from ending the thread path, butting the inner thread of the tube on which it has been threaded. This means that, for example, the internally and externally threaded tube (14) has been threaded onto the internally threaded tube (13) by lifting the load, until the metal washer inserted in the groove (20) on the internal thread of the internally threaded tube (13) preventing the internally and externally threaded Tube (14) from continuing to twist, which causes the next Tube (15) to start rotating and so on until it reaches its maximum elevation. This groove (20) with its metal washer, can be replaced by any element that acts as a stop, such as a welding point, a small protrusion of material produced by stamping at the end of the tube or any other system that prevents passage of the thread of one tube over the other, an example is shown in drawing 5 in which material has been displaced from the bottom of the thread by means of a pressure cut so as to prevent the passage of another thread through this point.
    The internally threaded Tube (13) is joined jointly by the Spinning Tube Gear (9), either by welding, pressure mounting, knurling or other system that joins them together.
    The internally and externally threaded tube (14), to which the lower tube stop (20) has already been created, is inserted into the internally threaded tube (13) to the lower tube stop (20). At this time the upper tube Stop (21) is created in the Tube (14), either by introducing a ring in the groove, producing a small tear in the Tube (14), with a welding point or other system, so that the two tubes remain with the possibility of threading in part of their length, but preventing them from leaving each other.
    Subsequently, the internally and externally threaded tube (15) is introduced, to which the lower tube stop (20) has already been created, on the tube (14) until the end of the thread and the upper tube stop is created ( 21) in the same way as in the previous step.
    In the same way we proceed with the internally and externally threaded tubes (16),
    (17) AND (18).
    The externally threaded tube (19) is also manufactured with the lower tube stop (20) and is inserted on the internally and externally threaded tube (18). When the stop is welded, the anti-vehicle support (22) is welded at the upper end so that all the tubes can rotate freely, but can no longer be separated from the assembly they form.
    Finally, the upper bearing support (5) is attached to the internally threaded tube
    (13) so that they are tightly bound. This can be done by welding, crimping, crimping, rolling (figure 7), by means of pins etc.
    Above all this set of mounted tubes is assembled the assembly that will turn the tubes to fulfill their function. Two ways of carrying it out are considered in the present invention:
    In the first option is the one explained in patent application P201530051 dated January 16, 2015, in which the transmission of the movement is done by a ratchet system.
    In this case the operation is as follows:
    The slotted washer (9a) joins the internally threaded tube (13) by means of welding, pressure mounting, knurling, gluing or other system that fixes them jointly.
    The ratchet shaft (10a) the ratchet spring (11a) is mounted on the lower base of the ratchet assembly (7a) and the ratchet shaft stop pin (12a) is mounted. The lower Base ratchet set (7a) is introduced with all the above mounted on the internally threaded tube (13) at the bottom and which is already mounted with all tubes (14), (15), (16), (17 ), (18) Y (19) And that is already attached to the upper bearing support (5). The upper body of the ratchet assembly (8a) is inserted through the upper part of the internally threaded tube (13) and is attached to the lower base of the ratchet assembly (7a) by means of screws or self-closing clips manufactured in the same upper ratchet assembly body and lower so that they are tightly bound.
    The operation is as follows. A lever is introduced in the lifting lever Drill (23a) that has a certain angle to facilitate the position of operation of the jack, making this position higher from the ground. This lever is pulled by a rotation of more than 90 degrees, when making this turn the Ratchet Shaft (10a) that is inserted into the groove of the slotted Washer (9a) rotates this washer which as it is attached to the internally threaded Tube (13 ) rotates it, causing the internally and externally threaded Tube (14) to rise unscrewing from the Tube (13). At the end of this angle of rotation of more than 90 degrees we turn the same angle in the opposite direction, now as the ratchet shaft has a chamfer in this direction of rotation it is pushed back pushing the ratchet spring (11a) passing over the grooves of the Grooved washer (9a) without causing displacement of this grooved washer and therefore the internally threaded tube (13) does not move. When the starting point is reached, the lift lever starts the cycle again causing another turn of the internally threaded tube (13) and achieving another jack lift. This is repeated until the tube (14) is blocked by resting the lower tube stop (20) on the inside of the pipe thread (13). When locked, the next tube (15) begins to unscrew and so on until the vehicle is raised to the desired height to be able to remove the wheel and introduce a new one.
    To lower the assembly, the ratchet shaft (10a) is pulled until it is released from the slot, rotated 180 degrees so that the ratchet shaft stop pin (12a) re-enters the slot of the lower base ratchet assembly (7a), and by pushing the force in the opposite direction, we lower the jack, and in the same direction the ratchet assembly moves without causing any movement when the ratchet shaft jumps over the grooves. So on we lower the cat until the vehicle rests the wheels on the ground and allows us to release the cat.
    Second option:
    In the second option, this movement transmission is done by means of gears. This second option has the advantage that for a cost similar to that of the ratchet, the torque exerted on the crank by the user is smaller to achieve the lifting of the load, difficulty that exists in the ratchet system to lift heavy vehicles type pick- up or SUVs.
    In the event that the movement is transmitted by means of gears, the operation is as follows: The Spinning Gear tube (9) joins the Tube (13) jointly through welding, pressure mounting, knurling, gluing or other system that one strongly, the lower Base set gear rotation (7) is inserted into the internally threaded Tube (13) in the lower part and which is already mounted with all the Tubes (14,15,16,17,18,19) and that It is already tightly attached to the upper bearing support (5).
    The upper body gear turn assembly (8) is introduced through the vehicle anti-rotation support (22) into the internally threaded tube (13). This element, as well as the lower Base set of gear gears (7), will preferably be made of a plastic material type POM or similar, to reduce the weight of the assembly. It can also be manufactured in sheet metal by stamping, although it will increase the weight of the set. These 2 elements will be joined together by means of screws or closure clips made of the same plastic, so that they remain tightly bonded.
    Prior to assembly, the Drive Gear (10) must be inserted into the Drive Gear Shaft (12) with its corresponding key and this shaft will be mounted when the Seeger Washer (11) is introduced. The assembly formed by the gears plus the upper and lower bodies, will be placed between the anti-rotation stops gear assembly (1 a) of the Base (1) so as to prevent its radial rotation when the whole assembly is mounted. This is the case when the gear set is mounted and cannot rotate on the internally threaded tube (13) because it is prevented by the anti-rotation gears set (1a) when not turning the gear set causes the rotational movement of the driving gear shaft (12 ) transmit the rotation to the Conductor Gear (10), this one, when turning, transmits the movement to the Tube Turning Gear (9) and this gear being jointly attached to the internally threaded Tube (13), rotates this tube, raising or lowering the Threaded Tube internally (14) until the lower or upper stops (20) or (21) stop at the internal thread of the tube (13) and the internally and externally threaded tube (14), this is how turning the shaft produces the rotation of the set of gears and tubes and cause rise or fall of the set of threaded pipes, getting the lift or lower of the vehicle.

    PREFERRED EMBODIMENT OF THE INVENTION
    As already indicated, the present invention corresponds to the patent application P201530051 dated January 16, 2015, and the application for the addition of palente of November 29, 2015.
    The invention consists of a metal Base (1) that will be manufactured preferably by drawing forming the radius of the spherical part of said base (1) on which the lower bearing Support (3) will rest, likewise the stops will be made in this operation anti rotation gear set (1st). This base will be manufactured with grooves in live edge at the bottom to prevent the base from rotating when lifting the vehicle.
    By cutting in stamping, the flat plate spring (2) will be manufactured, subsequently giving it the corresponding tempering and tempering heat treatment to achieve the typical characteristics of this spring steel (50CrV4) or similar.
    The lower bearing support (3) is also a metal part and will be manufactured by stamping, being subsequently treated to achieve a hardness in the support area of the axial bearing (4), this treatment can be a hardened, carbonated
    or also induction hardening.
    The axial bearing will preferably be of needles because it occupies less space than if it is of balls, helping to achieve the lowest height of the set.
    The upper bearing support (5) is also a metal part and will also be manufactured by stamping or drawing, likewise it will be treated later to achieve a hardness in the support area of the axial bearing (4), this treatment can be a tempered, carbonated or also induction hardening.
    The Moyú of subjection (6) will be manufactured preferably by mechanized
    The lower base gear turn assembly (7) and the upper body turn gear assembly (8) will be pieces of plastic, POM or similar material, to minimize the weight of the jack. They will preferably be manufactured by Injection to have a reduced cost.
    The tube turning gear (9) and the driving gear (10) will preferably be manufactured by cutting and drawing in the press. They are metal parts and since they do not need great precision due to the low operating speeds, which is the most economical way of manufacturing, they can also be manufactured by sintering in a slightly more expensive and more precise way.
    The seeger washer (11) is a commercial element.
    The driving gear shaft (12) is manufactured by machining in case of being metallic, there is also the option of manufacturing it by injection plastic.
    The threaded tubes (13), (14), (15), (16), (17), (18), Y (19) will be manufactured from a steel tube preferably in multi-spindle lathes, where the outside will be threaded lamination and the interior by cutting, leaving the finished piece. The beginning and end of the thread must be made in such a way that it makes a good stop against the upper and lower stops (21) and (20) so that the beginning of the cone thread is not left and with the threading effort can deform the tube allowing one tube to unscrew over the other. That is why the internal thread of the tubes must start and end abruptly and with a minimum radius that makes a good stop. Figure 5
    The lower tube stops (20) and upper tube stops (21) can be metal rings formed in special machines for this function (spring machines), which are inserted at the appropriate time in the slot. These stops can also be created on the tubes by welding, or by creating protrusions by drawing in the final areas of the thread or by drawing with a die Figure 5
    The vehicle anti-rotation support (22) is also a metal part and manufactured in presses by drawing.
    The assembly of the set is done as follows:
    one. The tubes, with the exception of the internally threaded tube (13), create the lower tube stops (20) either by mounting a metal ring, giving a welding point, or creating a stop by drawing or cutting the part (Fig 6)
    2. Subsequently, the internally and externally threaded tube (14) is inserted into the internally threaded tube (13). When it has reached a stop on the inner thread of the Tube (13) the Bottom tube stop (20) the ring is inserted in the upper part of the tube (14), this stop can also be achieved with a welding point or in a Press creating a cap by drawing or cutting the bottom of the thread. (Fig. 6)

    11-21-2016
    3. Then the tube (15) is introduced on the (14) and the same operation is performed to create the stops and so on until all the tubes are mounted.
    Four. On the last externally threaded tube (19) the vehicle support is welded. At this time all tubes can scratch each other or unscrew, but they can no longer separate from each other.
    5. The upper bearing support (5) is mounted on all this assembly. This bearing support can also be mounted by welding it, with a hook to the tube (13), by means of a roll on a groove created in the lower part of the tube ( 13) (Figure 7) or any other system that creates a strong bond.
    6. The Swivel Tube Gear (9) is mounted under pressure on the internally threaded Tube (13). In case you require it, you will be given a welding point, some type of knurling, hot mounting or similar, to ensure that they remain tightly joined,
    7. The gear assembly is assembled, formed by the lower base gear assembly (7), the driving gear (10) mounted on the lower base gear rotation assembly and the seeger washer (11). This subset is introduced by the upper bearing support (5) into the internally threaded tube (13). It is now introduced by the vehicle anti-rotation support
    (22) the upper body of the gear rotation assembly (8) and are joined both by screws or a click-type closure created for this purpose in the upper and lower bodies of the gear assembly (7) and (8).
    8. In the lower part, the axial bearing (4), the lower bearing support (3), the flat plate spring (2) and the base (1) are placed on the Upper bearing Support (5). When the whole assembly is mounted, the Moyú (6) is mounted under pressure or threaded and with this operation we have the whole assembly mounted.
    In the event that the option whose patent application is P201530051 is mounted, with the variations of the present patent addition, with the Ratchet system, the preferred embodiment of the invention would be the same until step 5 above. From having the entire set of tubes mounted with the vehicle anti-rotation support (22) and the upper bearing support (5) mounted, the next step would be:
    1. The slotted washer (9a) is snapped onto the internally threaded tube (13). In case you require it, you will be given a point of

    11-21-2016
    welding, some type of pressure mounted knurling, hot mounting or the like, to keep them tightly bonded,
    2. The ratchet assembly is inserted onto the internally threaded tube (13),
    formed by the lower base ratchet set (7a), with the ratchet shaft (10a)
    5 the ratchet spring (11a) and the ratchet stop pin (12a) mounted. ThisSubset is inserted by the upper bearing support (5) into the tubeinternally threaded (13). It is now introduced by the vehicle anti-rotation supportthe upper body ratchet set (8a) and are joined both by screws or aClick closure created for this purpose in the upper and lower bodies of the set
    10 ratchet (7a) and (8a).
    3. In the lower part, the axial bearing (5), the lower bearing support (3), the flat plate spring (2) and the base (1) are placed on the upper bearing support (5). When the whole assembly is mounted, it is mounted under pressure or
    threaded the Moyú of subjection (6) and with this operation we have the whole set
    15 mounted.
    INDUSTRIAL APPLICATION OF THE INVENTION. The industrial application of the invention is clearly derived from the foregoing explanations, only that the invention is not only for vehicle lifting, but
    20 also to lift any other type of part, assembly or component that needs to be elevated and is within the limits of stroke and load of the assembly of the present invention.
