Description

Detachable coupler device for an engine and a support, particularly for tubular motors for units winders and the like.

The present invention refers to a separable coupling device for a motor and a support, particularly for tubular motors for winding units and Similar.

As is known, tubular motors, which are used to drive winding units in general, such as blinds, awnings and the like, they are fixed in one of their ends to the support of the winding unit. The engines are provided with a career limiting electrical system and once installed must be adjusted by a system that is operated by a screwdriver; for this reason, the adjustment screws must be accessible and therefore it should be possible to install the engine with different angular positions.

Generally, the tubular motor head is fixed on a stand that has the same profile as the head and is then fixed to said head, by various systems such as screws, split pins, crossbow clamps and the like, in order to prevent axial disengagement of the head.

This type of operations is delicate and in some laborious cases due to the precarious conditions of installation and requires considerable attention and timing relatively long installation.

In order to try to solve the problem, systems to automatically fix the tubular motor head to Rolling unit support have already been designed accordingly facilitating assembly, which is safer and faster.

Systems of this type use a plate intermediate, which is fixed to the motor head by screws and is profiled to allow coupling for hitch Automatic to engine mount.

EP 0 468 925 shows a hitch system automatic consisting substantially of three components, that is, a head, a support and an elastic ring fixative.

Although this embodiment allows the automatic coupling, does not allow to unhook the motor head in a confined space, since it is necessary to extract in a radial direction the elastic ring that provides the coupling in an axial direction.

In addition, in order to remove the elastic ring it is necessary to use a tool that, when operating in very spaces confined, it makes the operation much more difficult.

The objective of the present invention is solve the problems described above, providing a coupling device with automatic fixing that allows engage and disengage the motor in a very small circular space and therefore it can also be applied where space available be particularly confined.

Within this objective, an object of the invention is to provide a coupling device that does not require intermediate components and in any case have no parts that can be released or separated from the other components.

Another object of the present invention is to provide a coupling device that can be operated manually without having to resort to the use of any type of tool.

Another object of the present invention is to provide a separable coupling device that thanks to its particular constructive features be able to offer the greatest guarantees of reliability and safety in its use and also competitive from a purely economic point of view.

This goal and these and other objects that they will be apparent better then they get by a device for separable coupling between a motor and a support, particularly for tubular motors for winding units and the like according to the invention, comprising a coupling head that is formed at the axial end of a tubular motor and a support that can be connected to a structure fixed, being provided peripheral gaps open axially in said head for detachable hitch with pins corresponding formed by said support, characterized by the fact that it comprises, in said support, pairing means automatic that can be inserted in seats provided in the peripheral region of said head and can be disengaged by a manual radial branching action.

Other features and advantages will result better apparent from the detailed description of a device for separable coupling between an engine and a support, particularly for tubular motors for units winders and the like, illustrated by a non-limiting example in the accompanying drawings, in which:

Figure 1 is a schematic view of the coupler device according to the invention, applied to a motor tubular;

Figure 2 is a view of the coupling head separated from the support, before pairing;

Figure 3 is a sectional view, taken at along line III-III in figure 2.

Figure 4 is a partially sectional view. of the pairing between the coupling head and the support;

Figure 5 is a sectional view, taken as along the line V-V of figure 4;

Figure 6 is a partially sectional view. of the step for decoupling the head and the support;

Figure 7 is a perspective view from the support and the coupling head.

With reference to the figures, the device for the separable coupling between an engine and a support, particularly for tubular motors for winding units and similar, according to the invention, comprises a coupling head, generally designated by reference number 1, which is disposed at the axial end of a tubular motor 2 that drives a winding unit consisting of a blind, an awning or Any conceptually similar element.

The device further comprises a support 3 that It can be connected to a fixed structure and can be matched with a head 1.

In greater detail, head 1 is provided peripherally of peripheral gaps 10 that are open axially and are spaced by lobes or bumps 11 equally distributed along the circumference.

Correspondingly, the support 3 is provided of a base plate 20 that is substantially circular and from which pins 21 protrude along a direction that is parallel to the axial direction; said pins can be inserted separably in the gaps 10, which are axially open.

A particular feature of the invention it is constituted by the fact that there are automatic means of pairing provided for coupling between head 1 and the support 3, said means being constituted by teeth 30 formed by sectors 31 supported by elastic arms 32 which protrude from base 20 of support 3.

The teeth 30 can be inserted in seats 40 provided in head 1.

The teeth 30 have a front bevel 30a that allows automatic insertion and have, on the opposite side, a stop region 30b which in practice enters the seat 40 with the In order to get stable pairing.

Advantageously, there are two sets of teeth, that are arranged diametrically opposed to each other and can branch radially using a single hand, seats 40 instead being provided in all lobes or bumps 11, accordingly allowing to perform mutual angular adjustment to through 90ºC thanks to the possibility of four positions different along an angle of 360 ° C.

With the provision described above is by therefore possible to get automatic insertion in one direction axial and it is also possible to perform decoupling simply radially branching the sectors 31 that support the teeth 30 protruding from the seats 40, allowing the axial removal of the head and accordingly the tubular motor coupled to it.

From what has been described above it is therefore evident that the invention achieves the objective and the intended objects, and in particular an inventive device it is provided that it is very compact in terms of its radial extension and also prevents the use of separate elements; It is constituted simply by two components and is operable simply with the hand.

In practice, the materials used, with the condition that they be compatible with the specific use, as well as the contingent shapes and dimensions can be any according to the requirements.
