Description

Window trolley.

Object of the invention

The invention relates to a drag carriage with a moon stand components of a window regulator system with the which can be quickly assembled and disassembled from the moons without the use of tools, devices, other auxiliary equipment or specialized labor, since the system is equipped with the necessary elements to carry out positioning, fixing, centering and pre-assembly in any product that requires it and in our particular case at the doors of motor vehicles.

Traditionally, both for placement specific of the moon in its corresponding support as of the adaptation of this to the device that is placed on the doors of the vehicles, by any of the known systems until the present moment, it is essential to use tools for fixing the moon, either by means of screws or other clamping systems that require drilling the previous moon to mount or use hook means of your moon stand if It is not drilled by staples and is placed in a clamp. So same, in all cases it is necessary to use hand of specialized work since a certain skill is required for the development of assembly and disassembly operations of the moon on its support and both on the displacement device of rise and fall of the corresponding window regulator, the same is Try the task of assembling as the disassembly of the system.

Assembly and disassembly operations result laborious, of some difficulty, for having to attend to the placement, centering and alignment of the window lift system to same time as the fixation with tools, and of higher cost and industriousness than with the technique proposed in the invention.

With the use of this invention is achieved that all the operations of mounting the moon stand to the car of drag carried out in horizontal position of the carriage of drag without having to expressly find a correct position position between both parties, since the integral components in assembly and disassembly operations they form a single respective unit with the moon and carriage support corresponding drag, which terms make assembly and / or disassembly are simpler, faster and lower cost, both for its need for labor without specialization and for the absence of tools and / or tools and the unnecessary use of energy, be it electric, hydraulic or pneumatic.

To do the above, the drag car It has two protuberances or pivots of positioning where fit two holes of the moon stand in an easy and fast given that one of the holes is of the coliso type (torn) and positioning bumps or pivots have a figure cylindrical finished in conical shape to facilitate its Introduction and positioning.

Also to center the union of the carriage Drag with the moon stand on the vertical axis, arrange the moon support of a rib that acts as a stop in your contact of approach with a flat plate of support of the car of drag, area where the prismatic system formed by two prisms, aligned at the top of the car with a free zone intermediate, which make contact with one of the supports Moon sides of the moon stand.

This placement of both elements, carriage Drag and moon stand, allow pre-assembly work be very simple and, above all very fast, since it is done by the assembly operator with the action of the hands only without Need any tool, because two flexible claws to spring mode and trigger shape, located on both sides side of the drag car, they hook to their respective stops similar to a barrel adapting to them, being placed at the ends of the moon stand, getting with this adaptation between both an immobilizing preassembly.

And for all components to perform their committed within being configured in one piece there are two levers on the moon stand with spring effect and are placed in the same alignment of their axes parallel to the moon plane and in the same axis of the holes of the support of Moon and grooves and claws in the case of the drag car.

It is an objective of the invention a car of drag with moon support preferably made of material plastic, with sliding guide and necessary components to perform self-centering, alignment, fixing operations and preassembly forming an integral part of the drag car in a single piece located therein, and also with the components located on the moon stand that are part member of it in one piece.

Another object of the invention is a carriage of drag with moon support with two misaligned housings where the tractor cable terminals are placed for the rise and window lift down.

Another object of the invention is a carriage of drag with moon support with a geometric system of vertical positioning and alignment consisting of two prisms located at the top of the drag car and a rib arranged on one of the moon's support faces on the support of Moon.

Another object of the invention is a carriage of drag with moon stand with two protrusions or pivots of positioning located on the front face of the drag car located its axes of symmetry perpendicular to the plane of the Moon.

Another object of the invention is a carriage of drag with moon stand with two flexible claws crimped located on the side ends of the carriage drag

Another object of the invention is a carriage of drag with moon support with two specific shape stops similar to a barrel located at the ends of the support Moon.

Another object of the invention is a carriage of drag with moon support with two levers with spring effect arranged on the front face of the moon stand as part of the same.

It is, finally, another object of the invention a drag carriage with moon support that allows its assembly and disassembly without using any tool or device.

These objectives can be implemented by a drag car system with a moon stand that It has a sliding guide on its back for fit in the door of the vehicle, with various housings and outgoing that allow to perform other location functions auxiliary elements or reinforcement of the drag car itself, not specifying at any time the use of tools or others devices or specialist personnel for assembly and / or disassembly

The shape of the drag car, built in lightweight material such as plastic, has a sectional appearance triangular quasi-isosceles, and has two prisms with their axis parallel to the plane of the moon and located on the upper edge of the drag car and a flat plate on the back of the car and in its upper area being its plane perpendicular to the moon. There is a space of separation between the two prisms, and a common axis of alignment between each of the prisms and their space of separation, all this on the front face of the drag car.

This drag car has two housings that are two emptied in the form of a rectangular section, misaligned with each other and vertically, with a hole in each housing that allows the cable terminals to be inserted traction and mooring of the same, located the latter in the face rear of the drag carriage and in its upper or lower position  of each rectangle.

At the lateral ends closest to the part The upper part of the carriage is located two grooves in U-shaped outward and to its upper edge, one for each side.

On those same ends there are two flexible claws Trigger-shaped that are born on the back of one's own drag car, forming an integral part of it and in the area close to the grooved "U" and its crimp shape has a strangulation in the area closest to his birth, one protrusion on its outer part, and another on its end and on the part inside of it.

On the front face of the drag car, forming an integral part of it, there are two bumps or hollow positioning pivots, conical at the beginning and conical trunk at its final protruding limb and located near U-shaped grooves, aligned with each other and with respect to the emptyings and the barrel-shaped stops, with their axes perpendicularly arranged with respect to the moon located in the moon stand

The moon stand of the window lift system It has two through holes, one of them circular and the other colossus (torn) located each near the ends of the moon stand, aligned with each other and with respect to the grooves in "U" shape and the claws of the drag car.

On the moon stand there are two stops, one on each side of its ends, and forming an integral part thereof, two stops with a barrel figure and a central recess in each stop in semicircular sense, which are an integral part of the support also, although arranged in a housing of said support of Moon. They are aligned with the round and colossus holes of the stand moon, claws, "U" grooves of the drag car and the claws hooked.

The moon stand has two levers with effect spring and are placed in the same alignment of their axes parallel to the moon plane and on the same axis of the holes and barrel-shaped stops of the moon stand and claws flexible, the "U" grooves and the two bumps or dragging car positioning pins.

The operability of this drag car with Moon stand is made by claiming, by the invention, a single piece for each of the elements that form the elevator of moons and that are the drag car and the support of moon, with its corresponding elements both the drag car on the one hand as the moon stand on the other.

The moon stand is placed in front of the front face of the drag car positioning the coliso and round holes of the moon stand next to the bumps or pivots of positioning of the drag car while facing the geometric system of prisms with the base of the lateral support of the Moon support bracket and the flat top plate of the carriage drag stops with the rib.

The above mentioned bumps are fitted or positioning pivots in the holes of the moon support by pressure of the moon support against the carriage, carried out only with the hands of the operator with a simple effort of tight.

As a consequence of the elasticity of the material of plastic or similar protrusions or pivots of positioning, and its initial truncated cone shape, you get a smooth penetration and with little effort, and its cylindrical shape in the rest of the piece the fixing of the support of moon to the drag car.

Next, the preassembly of the moon stand with the drag car exercising, with your hands, a slight pressure on the outer protuberance of each claw flexible.

With a minimum effort you can make a rotary movement of the flexible claw due to throttling that has this flexible claw near its birth or onset

This action of the flexible claws can be done with each hand to place them on the top similar to a barrel, placing the inner shoulder of the end of the claw flexible over a small recess that is in the center of the top of similar to a barrel and so it is coupled and preassembled the Moon stand with the drag car.

The action of the two levers with spring effect, located on the moon stand, they exert a pressure on it the car which results in this pressure acting from a indirectly on all fixing components and preassembly between the moon stand and the drag carriage what results in the maintenance of the coupling force, achieving so for the work they do and the duration in time of same compensate the corresponding wear, and avoid noise counterproductive

To disassemble both pieces (moon stand and drag car) you just have to act on the flexible claws exerting a small effort on its exterior highlight in the opposite direction to the hitch and is achieved the release of the barrel-shaped butt claws to which They had adapted. Then a slight effort of separation, in the opposite direction to the face of the two pieces, and get the separation of both. Also without the need for tools, tools, complementary energy or labor specialized, with the consequent cost savings of disassembly
