The present invention relates to tubular actuator for actuating winding element in the building, such as blinds, sun screen, or a screen for the projection of images spooled blinds. Tubular drive is installed in the pipe winding, which is wound wound element.

It contains the end piece, which is connected with the support part and which must withstand the weight of the drive pipe and wound element, typically half the weight, and to withstand the torque of the actuator. This end piece is often called "fixed point" or "head" of the drive.

Therefore, the size of the drive head must be calculated so that it could withstand mechanical stress, and also held the minimum dimensions in the axial direction: indeed, wrap the item could not gather around the head, and therefore, the width of the head so reduces its width, if support is not provided special socket.

In addition, the cylinder connected to the support by means of fixing devices made with the possibility stationary mounting on a support, for example, by means of the bolts on the metal support or using zaspirtovannyh screws. Preferably the connection head with mounting hardware perform connector is output, that is, it can easily lock and unlock, to facilitate the installation and maintenance of the wound element or actuator. Various manufacturers have developed special fasteners, containing, for example, means of elastic snap and shape corresponding to the simultaneous perception of weight and torque. Such a fixing device described in document WO 2008/3765 (position 2 in Fig. 1). It is made with the possibility of installing the drive with a fixed point (position 4), consisting of only one part.

Preferably the actuator manufacturer should offer a wide range of actuators, which differ from each other only by the shape of the head. Hence the presence of an extensive range, which complicates logistics and affect prices. If the actuator manufacturer wants to streamline its proposal and represents only one type of head, thus he transfers the problem to producers wound elements and forces them to choose the solution for fixing, which is not always optimal for their products.

Finally, the head drive often must satisfy the requirements of integrity, related to possible use of the drive outside the building or in wet areas.

Drive experience at the plant, and the n receives the manufacturer's warranty. It is clear that this guarantee applies to all node fixed point, so the decision interchangeability becomes especially risky if beyond the scope of the production process, for example, if this solution can be implemented on the construction site. The interchangeability of the fixed point requires at least one intervention at the factory as part of the agreement between the manufacturer of the drive and the manufacturer using this drive in his article containing pipe wrap and/or wound element.

In the patent application WO 2009/016601 described head or fixed point of the tubular actuator, cylinder, or perform fixed point of two parts. The first part is almost completely inserted into the tube drive, and it includes means for locking the progressive movement in the pipe, which stopped with the introduction of the second part. Interchangeability can be realized with the proposed solutions.

However, it remains sensitive to the aforementioned stresses, if not only strengthen the role of the fastening means, not described in this document. The solution proposed in this application is of interest in that the locking of the mentioned means of blocking the translational movement is easy and requires no tools, but it also applies unlock that PR is tioricet the above safety requirements.

Similarly, the patent FR 2840012 patent application WO 2006/045724 or utility model DE 202007005138 reveal a fixed point, containing mechanical or electronic controls locking actuator (detection of torque, the calculation of the rotation, and so on) and means a mechanical or electrical connection with the tubular part of the drive. In German utility model fixed point contains the first removable portion, indicated by the position 9 and containing controls, and the second part, denoted by position 2, associated with the tube drive.

In these documents, the interchangeability does not provide adaptation to different types of fastening devices, and allows you to either produce the final mounting of the actuator on the construction site, or to make long selection of controls.

In this connection, the invention proposes a simple and economical solution interchangeability of heads of actuators, which satisfies the above requirements of mechanical strength against stresses and safety requirements.

In the present invention proposed a drive, which can eliminate the above disadvantages and to improve the known actuators. In particular, the invention allows to obtain a simple and cost-effective actuator providing interchangeable heads that meet the requirement of the requirements of mechanical strength and security.

According to the invention the tubular drive spooled element in building contains:

- gear motor in a tube with a longitudinal axis and an output shaft at the first end of the pipe,

- fixed point of two parts on the second end of the pipe,

at this fixed point contains the first part at least partially located outside of the pipe, and the second part collected in the pipe. The actuator is characterized in that the first part contains at least one axial continuation of the perception of time and weight, in fact the continuation of the perception of time and weight made with the possibility of overriding at least one recess of the second part and is now in translational movement along the longitudinal axis relative to the tube of the actuator, using a first means of locking.

The first locking means may be secured to the first part.

In this case, the first locking means may include a screw threaded in the first part, the opening for the passage of the screw in the second part, and a hole for passing a screw in the pipe.

The first locking means may be mounted on the second part.

In this case, the first locking means may include a screw threaded in the second part, a hole for passing a screw in the first part and a hole for passing a screw in the pipe.

The second frequent which can be locked in translational movement along the longitudinal axis relative to the tube of the actuator, using the second locking means, mounted on the second part.

The second tool locking may not freeze the translational motion of the first part along the longitudinal axis relative to the tube drive.

The second locking means may include a screw threaded in the second part, a hole for passing a screw in the pipe and, if necessary, the axial through-opening for the passage of the screw in the first part.

The specified at least one recess may be peripheral recess.

The object of the invention is also the equipment of the building containing the tubular actuator according to one of the preceding claims.

The present invention will be more apparent from the following description, provided solely as an example, with reference to the accompanying drawings, on which:

Fig. 8 is a partial view of the version of the second variant of the first part of the fixed point.

In Fig. 1 shows the equipment 100, containing a tubular actuator 1. Tubular drive contains a fixed point 2, the tubular body 3 and output shaft 4 made with the possibility of rotation around the axis x-X' of the tubular housing. The output shaft is connected with the pipe 5 winding, which sets the drive through the drive wheel 6. The bearing 7 provides direction in the rotation of the pipe winding on a tubular drive housing. The fixing device 8 connects the fixed point of the support 9. Not shown is wound element is fixed to the end of the pipe winding. The fastening device is fixed on a support, for example, in building construction. Preferably attached directly to this support. In addition, the fastening device is intended for installing a fixed point of the drive. For this purpose it contains, for example, the respective elements. Thus, the mounting device allows you to secure indirectly fixed point on the support.

The dashed line shows the plot of the fixed point 2, which enters the tubular housing 3.

In Fig. 2 in a partial parse is shown a tubular actuator in accordance with the present invention.

Fixed point contains the first part, indicated by the position of the 20 or 20' depending on the embodiments, and the second part, indicated by the position 40 or 40' depending on embodiments.

The first part is mostly external to the pipe and has less direct contact with the pipe than the second part. Thin dashed line 24A limits the latent phase of the first part. This latent phase varies depending on the implementation.

For the first part provides the possibility of interchangeability. Therefore, the outer part of the pipe can have different forms depending on the requirements of the manufacturers of wound elements.

Preferably the tube 3 are made of steel. In particular, it contains an aperture 33, which provides the locking in rotation of the second part, the first screw hole 34 made with the possibility of passage of the body of the first screw 37, and the second screw hole 35 made with the possibility of passage of the body of the second screw 38.

The first and second screws function as locking means between the pipe and the second part.

X-x' refers to the main axis of the pipe, which will further define the axial direction.

In Fig. 3 shows a first variant of the first part 20 of the fixed point.

The first part comprises a base 21, essentially round, at least in p is Ascoli, perpendicular to the pipe axis, and the relief elements 22 made with the possibility of going into the fixing device 8. The groove 23 made in the relief elements, provides a jammed by means of clamp fasteners. Alternative provide other locking means for holding the first part of the fastening device.

Round base contains the first axial continuation of the 24 in the form of a finger and the second axial continuation of 25, in this case identical to the first axial continuation. Round base contains also the third axial continued 26.

Axial continuation made with the possibility of perception part of the torque of the actuator, such as a torque of the actuator divided by the number of axial continuations, i.e. one third of the torque actuator. It is made with the possibility of perception of the weight of stocked products (drive pipe winding and wound element), for example, half the weight, divided by the number of axial extensions.

The first axial continuation contains the first opening 27 for the passage of screws, and the second axial continuation contains a second opening 28 for the passage of the screw.

Round base contains through the recess 29, which is designed for maintenance-free axial passage of the electrical connection of the of Italia through the first part.

In Fig. 4 shows the first embodiment of the second part 40 of the fixed point.

The second part comprises a cylindrical housing 41 made with the possibility of going into the pipe 3 or in direct contact with her, or with a gap sufficient for installation between the insulating tube (not shown)required for electrical insulation controls installed in a pipe of the drive. A cylindrical housing contains at least one internal crown 41A diameter equal to the inner diameter of the tube 3 to implement a tight fit. The outer crown 42 protrudes from the inner crown. Its diameter is equal to, for example, the outer diameter of the tube 3. The outer side of the outer crown is pressed against the circular base of the first part.

The tool 43 lock is achieved due to the axial continuation of the outer crown in the direction of the pipe 3 having a shape corresponding to the shape of the opening 33.

The second part contains the first peripheral recess 44 and the second peripheral recess 45. It also contains no peripheral recess 46. These recesses have a shape corresponding to the axial expansions of the first part, to make a connection in the groove with no gap (or with a slight gap) axial continuations 24-26 with hollows 44-46.

Two screw holes 47 and 48 are designed for screwing screws 37 and 38.

Second kwasna the notch 49 is designed to provide the axial passage of the electrical connector through the second portion opposite the first end-to-end recesses. In the second through the notch you can install the seal.

In Fig. 5 shows a second variant of the first part 20' of the fixed point.

The second variant differs from the first variant only by the length of the first or second axial continuation, in this case, the first axial continuation 24', which is shorter than the first axial continuation of the 24 in the first embodiment, so that through him was not the first screw 37. The second axial continuation of 25' in the second embodiment is identical to the second axial continuation of the first variant of implementation and includes a second hole 28' for the passage of the second screw 38.

In Fig. 6 shows a second embodiment of the second part 40' of the fixed point.

The second part contains the first peripheral groove 44' and the second peripheral recess 45' and is different from the second part of the first variant only axial length of the first peripheral grooves 24', which is shorter than the first peripheral recess 44 of the first variant of execution to the first screw hole 34 was not opposite the first peripheral recess 44'.

Two threaded holes 47' and 48' are designed for screwing screws 37 and 38.

It is evident from Fig. 5 and 6 it follows that in the second embodiment, the first screw 37 allows freeze in translational motion is only the second part with the pipe, while the second screw 38 allows you to plug both the first and second parts together with the pipe. This can be an advantage in comparison with the first variant of execution in which both screws simultaneously perform the same role for locking the two parts with the pipe.

Indeed, the first screw 37 can be equipped first with a special head that requires a tool that is available only from the manufacturer of the drive, while the second screw may be provided with a second head that requires a tool, available simultaneously with the manufacturer of the drive and the manufacturer (or manufacturers) wound elements.

Thus, it is possible to control the interchangeability of the first parts of the fixed point in the best conditions of safety.

In the version of the second variant implementation, partially shown in Fig. 8, for the first axial continuation 24” preserved length equal to the length of the first axial continuation 24 of the first variant implementation, but the first opening 27 for the passage of the screw was replaced with a through axial opening 27”, made at the end of the first axial continue in the direction of the pipe. Thus, the first part is separat in the translational movement of the first screw, and, nevertheless, the first axial continuation saves a maximum of material for compliance with requirements in the perception of time and weight.

The third variant execution is compared with the first option, perform only the following differences:

the first part contains the first axial continuation containing the first threaded hole (corresponding to the first opening 27 for the passage of screws for screwing the first screw and the second axial extension, containing the second threaded hole (corresponding to the second opening 28 for the passage of screws for screwing the second screw;

- the second part contains two smooth holes (corresponding to the two holes 47 and 48), designed for going down the ends of the first and second screws; preferably the ends of these screws go into the holes without screwing. In particular, these openings comes only pointed end of the screw.

The fourth variant execution is compared with the second option perform only the following differences:

the second axial continuation contains a threaded hole (corresponding to the second hole 28' for the passage of screws for screwing the screw;

- the second part contains a smooth hole (corresponding to the hole 48)designed for going down the end of the screw mentioned in the previous paragraph; preferably the end of this screw goes into the hole without screwing. The end of the screw may include a thread, but is preferably smooth

Version of the fourth variant execution is compared with the version of the second option, perform the following differences:

the second axial continuation contains a threaded hole (corresponding to the second hole 28' for the passage of screws for screwing the screw;

- the second part contains a smooth hole (corresponding to the hole 48)designed for going down the end of the screw mentioned in the previous paragraph; preferably the end of this screw goes into the hole without screwing.

Different ways to perform and versions can be combined with each other. For example, the first part may include a first axial continuation containing the first screw hole for screwing the first screw and the second axial extension, containing a second smooth bore for going down the second screw, while the second part contains the first smooth bore designed for going down the end of the first screw and includes a second threaded hole for going down the end of the second screw. Alternative screws, screwed up in the first part, can not pass through and, therefore, not to go into the holes of the second part. Thus, the presence of holes of the second part is not necessary.

Within this document you must understand the term "inner thread" as an element of running a tap in the twistie, as well as an element, perform self-tapping screw in the hole, and in this case the thread before the first passage of the screw in the hole do not perform.
