Description
- The present invention relates to a chain-drive actuator that is useful particularly but not exclusively for the closing and opening movement of horizontally-hinged windows and doors.
- As is known, chain actuators that allow effective movement of leaves, particularly of the horizontally-hinged type, have long been used in various fields of application and in particular in the field of doors and windows.
- Various constructive types of chain-drive actuator are currently commercially available.
- However, despite the variety of technical solutions adopted, such types substantially comprise a box-like body that accommodates motor means, usually constituted by an electric motor, which are connected to a reduction unit, which is in turn coupled in output to an actuation unit, substantially constituted by at least one chain.
- In commercially available actuators, the chain normally occupies all of the space inside the box-like containment body, sliding along its entire length and movement path within corresponding guides, which cause the actuator to become constructively very complicated and bulky.
- Moreover, the shape assumed by the longitudinal extension of the chain inside the box-like body is substantially defined by the contour and dimensions of said body.
- The chain is normally arranged so that its portions are substantially parallel to the walls of the box-like body.
-
GB-A-2 159 600 - The aim of the present invention is to provide a chain-drive actuator that solves the drawbacks noted in commercially available actuators and ensures high constructive simplicity, without thereby detracting from functional qualities and performance in application, and reduced dimensions.
- The problem met by the present invention is how, during retraction of the chain, to constrain the chain of the actuator to obligatory form elongated loop formations in compact side by side relationship.
- Within this aim, an object of the present invention is to provide a chain-drive actuator that is functionally flexible and can be manufactured in various sizes and with various traction capabilities depending on the requirements of the application.
- Another object of the present invention is to provide a chain-drive actuator that is constituted by a reduced number of components without thereby affecting the overall robustness of the assembly.
- Another object of the present invention is to provide a chain-drive actuator that can be easily associated with doors and windows even if they are already installed.
- Another object of the present invention is to provide a chain-drive actuator that can be manufactured with known technologies and systems.
- This aim and these and other objects that will become better apparent hereinafter are achieved by a chain-drive actuator according to claim 1.
- Further characteristics and advantages of the present invention will become better apparent from the following detailed description of an embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figures 1 to 3 are sectional orthographic projection views of a chain-drive actuator according to the invention in three different steps of operation;
- Figure 4 is a partially sectional orthographic projection view of a detail of the actuator of Figure 1.
- With particular reference to Figures 1 to 4, a chain-drive actuator according to the invention is generally designated by the
reference numeral 10. - The
actuator 10 comprises, inside a box-like body 11 that in this case has an elongated shape and is constituted by two mutually reversibly connected half-shells 12, motor means, generally designated by thereference numeral 13, which are connected to areduction unit 14, which in turn is coupled in output to anactuation unit 15, which comprises in this case achain 16 formed by links. - The
chain 16 has anouter end 17 that is preset to pass through acorresponding opening 18 formed in the box-like body 11. - The
actuator 10 also comprises guiding means, generally designated by thereference numeral 19, for thechain 16, which comprise aperipheral guide 20, which abuts against corresponding internal walls of the box-like body 11 and is suitable for the external guiding and containment of thechain 16, and aguiding slot 21, which is formed at thebottom 22 of the box-like body 11 and in which a correspondinginner end 23 of thechain 16 is slidingly guided so as to form a movable stroke limiter during traction and retraction. - In particular, the
peripheral guide 20 is constituted by a plate-like element 24 which is longitudinally U-shaped, abuts against the box-like body 11, and has an L-shaped end portion that is directed toward the opening 18 of the box-like body 11, so as to guide thechain 16 toward the opening by redirecting it. - In practice, the inner
longitudinal edge 24a of the plate-like element 24 guides thechain 16 because it is arranged within the dimensions of thechain 16, between the upper andlower link plates 35a and 35b of eachlink 36. - The plate-
like element 24 hastabs 25 for positioning and engagement with respect to the box-like body 11. - The
slot 21 comprises afirst portion 26, which is substantially parallel to the longitudinal walls of the box-like body 11 and whosestart end 27 forms an outgoing stroke limiter for thechain 16, and continues with asecond portion 28, which is inclined with respect to thefirst portion 26 and ends with anend 29 that is arranged in a substantially central region with respect to the transverse dimension of thebody 11 and is proximate to the corresponding end thereof. - In particular, the
inner end 23 of thechain 16 is associated with apin 30 that is slidingly inserted in theslot 21. - The guiding means 19 cooperate to arrange the
chain 16 so that itsportions 31 are substantially parallel to the longitudinal walls of the box-like body 11, wound spirally during traction and retraction. - In particular, in this embodiment the
chain 16 is contained within adelimited portion 32 of thebody 11. - The motor means 13 are constituted, in this case, by an
electric motor 33, whoseaxis 34 is arranged substantially obliquely with respect to the longitudinal direction of thebody 11. - The
reduction unit 14, in this case, is of the gear type. - In practice, the operation of the
actuator 10 is as follows. - Assuming that one begins in a step in which the
chain 16 is completely wound inside the box-like body 11, the action of themotor 33, by means of thereduction unit 14, produces during extraction the sliding of thechain 16, which is contained in its path internally by the very arrangement of its links and externally by theelement 24, whose L-shaped redirection proximate to theopening 18 allows to direct thechain 16 toward the outlet. - The
chain 16 can be extracted to its full length until thepin 30 reaches theend 27, which determines the outgoing stroke limit for thechain 16. - During retraction, again under the action of the
motor 33 with the mediation of thereduction unit 14, thechain 16 is redirected initially in the correct retraction path substantially by theelement 24, which guides it along the first turn of the spiral. - At the same time, the
pin 30 slides toward theend 29, where it is retained, causing thechain 16 to spontaneously coil up on itself, thus forming the core and the hinge-like coupling about which the remaining part of thechain 16 winds conditionally. - In practice it has been observed that the present invention has achieved the intended aim and objects.
- In particular, it should be noted that the actuator according to the invention allows an optimum level of functionality and robustness while ensuring an overall structure that is constituted by a reduced number of components, thereby providing considerable cost reductions in production and manufacturing.
- It is also noted that this constructive simplification in no way impairs flexibility of application, which can be the most disparate according to different requirements of application.
- It is also noted that the actuator according to the invention is easy to apply by the operator even optionally on-site.
- The present invention is susceptible of numerous modifications and variations, all of which are within the scope of the claims.
- The materials may be any according to requirements.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
