JP6155046B2 - Awning with vibration damping drive - Google Patents

Description

  The present invention relates to an awning having a characteristic structure described in the preamble part (preamble part, so-called writing part) of claim 1.

  This type of awning has a basic structure that has been known for some time. This foundation structure is wound on a tent curtain shaft, a base member that can be attached to a part of the building, two holding brackets arranged on it, a tent curtain shaft that is rotatably mounted between them. It also has a sunshade tent curtain that can be unwound from the shaft, and a motor drive device that is incorporated into the tent curtain shaft to rotate the tent curtain shaft. It is attached so as to attenuate vibration. The term “foundation member” refers to any configuration capable of securing an awning, such as an articulated arm shade, a greenhouse awning or a window awning, to a part of a building such as an outer wall, a greenhouse or a window reveal. Means an element. For awning designs, this type of foundation member typically has an awning housing, a mounting panel, a mounting frame, and the like.

  In particular, when the sunshade is automatically operated by an intelligent control system, the sound generated during operation becomes a problem. Awnings with daylight, wind and / or rain sensors are wound or unwound at different times depending on the user's control parameter settings. With this method, for example, when the sun begins to shine, it is possible to automatically solve the awning. In this case, the noise generated from the mechanical drive is transmitted through the building structure and air. This noise is extremely unpleasant for the building tenant as it can disturb peace or even disturb sleep.

  So far, various manufacturers of awnings and awning drives have made efforts to minimize this noise from mechanical drives to achieve passive noise reduction. That is, low-vibration fixed bearings are known for general preferential use. This is integrated in the form of an elastomeric sound absorber into the holding bracket of the motor drive unit incorporated in the tent curtain shaft, and is the product name “dB Absorbing Bracket (dB) of Somfy GmbH (72108 Rottenburg / Neckar, Germany). Absorber Bracket) ", product number 9015223. The disadvantage of this low vibration bearing is that it is located between the sunshade holding bracket and the motor head. For this reason, it is necessary to shorten the tent curtain shaft in a predetermined width of the shade, and as a result, it is necessary to use a narrower tent curtain, thereby reducing the area of the shade.

  A completely different idea regarding noise reduction is disclosed in Patent Document 1. The system utilizes a noise impact system with a sound actuator that is used when the awning is wound or unwound so as to reduce the sound and noise emanating from the awning components on which the actuator operates. Generate an opposite sound pattern that matches the resulting acoustic pattern. This system is much more complex than a passive vibration and noise attenuation system because it requires additional acoustic equipment.

DE 10 2010 029 881 A1

  Based on the above-mentioned problems of the prior art, the object of the present invention is to improve the awning using a purely mechanical noise reduction system so that the area of the shade is not reduced when the damping part is installed. is there.

  This object is achieved by the features described in the characterizing part of claim 1. According to this, there is provided a vibration isolator disposed completely between the motor drive device and its fixing holding bracket inside the tent curtain shaft. The motor drive is protected against rotation by a support head within the tent curtain shaft. Along with this support head, a radial damping member of flexible vibration damping material is positively (forced; shape-constrained) engaged with the motor drive in the direction of rotation. Subsequently, the assembly is fixed to the holding bracket by means of a mounting head, in which case the mounting head is arranged so as not to rotate with respect to the holding bracket and reliably engages the damping unit in the direction of rotation.

  The mounting head, the radial damping member and the support head are securely engaged with each other in the direction of rotation of these components, so that the motor drive device and the holding bracket arranged in the tent curtain shaft Complete vibration isolation. Both the support head and the mounting head as well as the radial damping member are fully integrated within the tent curtain shaft, thereby eliminating the need to shorten the tent curtain shaft, unlike the prior art. Therefore, using the shade according to the present invention does not reduce the area of the shade.

  The support moment of the motor drive device that occurs when operating the tent curtain shaft is transmitted to the holding bracket via the above-described components that are securely engaged. At this time, the radial damping member is caused by its flexible characteristics. Compressed.

  According to a preferred embodiment of the invention, the support head is designed as a non-circular external feature part (external contour part) extending in the axial direction of the tent curtain shaft and closed in a radial damping member-ring shape. The shape of the component—is slid into the external feature part described above. When viewed in the axial direction of the tent curtain shaft, this radial damping member is formed by a plurality of radial damping rings arranged in a row, thus improving the mountability. Due to the arrangement in the tent curtain shaft, both the support head and the mounting head can be longer or shorter in the axial direction depending on the required damping characteristics. The longer the support head and the mounting head, the longer the radial attenuation member, in other words, the greater the number of radial attenuation rings arranged in a row.

  According to a preferred embodiment of the invention, it is possible to design the mounting head as a non-circular bell-shaped internal feature part extending in the axial direction of the tent curtain shaft, similar to the case of the support head. In that case, a radial damping element—in the form of a ring-closed component—is fitted together with the support head into the internal feature part. Therefore, the three components of the vibration isolator, namely the mounting head, the radial damping member and the support head, are arranged coaxially inside the other, so that the very compact of the vibration isolator is Design is realized.

  A particularly efficient torque transmission between the support head and the radial damping member can be realized by making the cross-section of the two components star-shaped, and thus the drive torque applied by the motor drive Reliable communication is ensured.

  Similarly, the cross-section of the mounting head is designed as a flower-like internal feature part with a corresponding outer cross-sectional profile of the radial damping member to optimally transmit the momentum generated when the motor is installed. A stable connection between the two components is ensured.

  By arranging the components of the vibration isolator coaxially, a large space inside the tent curtain shaft, which is initially vacant, is optimally utilized. The radial damping member should have a length that is at least twice the outer diameter size of the cylindrical motor drive housing to have an advantageous effect on the damping characteristics.

  The damping characteristics of the vibration isolator can be further improved by an axial damping member between the mounting head and the support head. This damping member is also made of a flexible vibration damping material and thus prevents vibrations from being transmitted from the front end side of the support head extending in the axial direction. For this reason, it is desirable to arrange this axial damping member between the aforementioned tip side and the bottom surface of the receiving part forming the internal feature portion. This axial damping member may be a disk having an outer contour that matches the internal features of the mounting head. This ensures that the disk can be reliably placed inside the mounting head just like the radial damping member and can therefore be held securely in place.

  The mounting head, the support head, and the axial damping member, if present, can each be provided with a motor drive connection or a through hole for the control cable, thus ensuring a secure connection to the motor drive. Power supply and control are ensured.

  For example, a foamed plastic material designed as a closed cell modified PU foam material with a shore hardness of 30-40 provides all the parameters that are advantageous for the use of the present invention.

  According to another preferred embodiment, the foamed plastic material has a compressibility of 40%. That is, it can be compressed to 40% of its original volume without permanently losing its foam structure and flexibility. This provides a damping behavior that is well adapted to the intended use of the radial and axial damping members, while at the same time guaranteeing a long service life. The wear resistance of the vibration isolator according to the invention is further greatly improved by another structural means. According to this, a rotation stopper is provided between the support head and the mounting head. In this case, the rotation stopper is preferably attached to the support head in order to limit the rotation angle between the two components. This rotational stop prevents excessive compression and thus prevents the radial damping member from being destroyed by relative torsional motion between the support head, the radial damping member and the mounting head. As soon as the rotary stopper is activated, the motor drive's supporting moment is transmitted directly from the supporting head to the mounting head, so that the radial damping member is not subjected to any further torque increase and further compression. . Another function of the rotary stopper is to maintain the correct function of the awning when the radial damping member is worn or broken. The rotating stopper allows the bending torque of the motor drive device to be transmitted from the support head to the mounting head even if the radial damping member is damaged, so that the motor drive device does not essentially rotate inside the tent curtain shaft. It becomes possible to attach.

  According to the last preferred embodiment, the mounting sleeve is rotatably mounted on the mounting head of the vibration isolator for carrying the tent curtain shaft. Thus, the mounting head has a dual function that provides significant structural advantages. By attaching the tent curtain shaft to the attachment head via the attachment sleeve, the tent curtain shaft is surely supported at the optimum eccentric position, and uniform and smooth rotational movement of the tent curtain shaft is promoted.

  Further features, details and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying drawings.

It is a side view of the awning holding bracket viewed from the side of the tent curtain shaft. It is sectional drawing of an awning which follows sectional line II-II of FIG. FIG. 3 is an enlarged detailed cross-sectional view of part III of FIG. 2. FIG. 3 is an exploded view of a awning in the area of a motor drive having a vibration isolator. It is a side view of the support head of a vibration isolator. FIG. 6 is a view of the support head viewed from the direction VI of the arrow in FIG. 5. It is an axial sectional view of the mounting head of the vibration isolator. It is the figure of the mounting head seen from the direction VIII of the arrow of FIG.

  Referring to FIGS. 1-4, a partially illustrated awning has two retaining brackets 1 disposed on a base member not shown in detail. Only one of the two holding brackets 1 is shown in the figure. For the sake of clarity, the basic member for fixing the awning to the wall of the house or the like is also omitted in the figure.

  This awning is a housing awning in which several components are arranged in the housing 2. These components basically include a tube-shaped tent curtain shaft 3 attached between the holding bracket 1 and the second holding bracket shown in the figure. The tent curtain shaft 3 is described below. In addition, it is rotatably attached to the holding bracket 1. The awning tent curtain 4 indicated by a broken line in FIG. 3 can be wound and unwound by the tent curtain shaft 3. The movement of extension and retraction of the awning tent curtain 4 is not critical in the present invention. This can be done, for example, using a joining arm and a dropout bar together with a motor drive 5 arranged in the tent curtain shaft 3.

  The motor drive 5 includes an electric motor and a correspondingly designed intermediate gear and is arranged in a tube-shaped housing form 6. A so-called motor head 7 is disposed at one end of the housing form 6, and the motor driving device 5 is non-rotatably attached to the holding bracket 1 through the motor head 7 as will be described in detail below. At the opposite end of the housing form 6 there is arranged a drive plate 8 which is coupled to the tent curtain shaft 3 without being rotatable. Thus, the tent curtain shaft 3 can be rotated to wind or unwind the awning tent curtain 4.

  The motor head 7 is connected to the holding bracket 1 via a vibration isolator. The entirety of this vibration isolator is indicated by reference numeral 50, which will be described in detail below with reference to FIGS. 3-8, with the best overview shown in the exploded view of FIG. According to these drawings, a square member 9 is attached to the motor head 7, and this square member 9 protrudes from the motor head in the axial direction of the tent curtain shaft 3 and is fixed thereto by a bolt 10. A support head denoted by reference numeral 11 having an inner square portion is fitted on the square member 9, and as a result, the support head 11, the square member 9, and the motor head 7 are connected to each other without being rotatable. The support head 11 has a non-circular outer feature portion 14 starting from its disc-shaped base 13 which extends in the axial direction A of the tent curtain shaft 3 and is shown in FIG. Has a substantially star-shaped cross section. Each “beam” is formed by a corresponding axially parallel web.

  Three radial damping rings 16.1 to 16.3 are mounted on this support head 11 including the external feature portion 14. Each of the radial damping rings 16.1 to 16.3 has a star-shaped inner cross-section that is fitted back and forth on the outer feature portion 14 of the support head 11. The radial damping rings 16.1 to 16.3 jointly form a radial damping member 16 that positively engages the support head 11 when viewed in the rotational direction.

  The axial damping member 17 is a corresponding disk arranged on the front face 18 of the support head 11 and is made of a flexible vibration damping material, similar to the radial damping rings 16.1 to 16.3. Formed by a corresponding disc. A suitable material is, for example, a closed cell modified polyurethane foam with a Shore hardness of 30-40.

  The vibration isolator 50 is finally completed by the mounting head 19. The mounting head 19 is fixed to the holding bracket 1 by a fixing bolt 20 via another square member 21. The mounting head 19 is a bell-shaped component having an internal shape portion extending in the axial direction A of the tent curtain shaft 3. The inner feature portion has an inner cross section resembling a flower shape, and a radial damping member 16 that similarly has an outer cross section resembling a flower shape that matches the inner cross section of the inner feature portion is fitted therein. . In other words, the mounting head 19 and the radial damping member 16 reliably engage each other in the radial direction. Referring to FIG. 3, the axial damping member 17 is disposed in the mounting head 19 between the tip side 18 of the support head 11 and the bottom surface 22 of the receiving portion 23 that forms the internal feature portion.

  This figure shows that the length L of the radial damping member 16 formed from the three damping rings 16.1 to 16.3 is much larger than the outer diameter of the motor driving device 5, or the tent curtain shaft 3 and It also shows having approximately the same diameter length. If necessary, the support head 11, the radial damping member 16 and the mounting head 19 can have a longer length in the axial direction A. This is because the tent curtain shaft 3 is virtually free on the side of the drive plate 8, so that the motor drive 5 can be moved further in this direction, that is to the right according to FIGS. It is.

  A mounting sleeve 25 is rotatably mounted on the cylindrical outer surface 24 of the mounting head 19. The mounting sleeve 25 is inserted into a tube-like opening of the tent curtain shaft 3 provided on this side. That is, at this end, the tent curtain shaft 3 is rotatably mounted on the mounting head 19 and thus on the holding bracket 1.

  The mounting head 19, the support head 11, and the axial damping member 17 each have a connection hole for the motor driving device 5 and / or a through hole 27 for a control cable.

  With particular reference to FIG. 5, the support head 11 is provided with a rotation stopper 26. The rotation stopper 26 is designed as a bulge resembling a flower shape that bulges from the external feature portion 14 of the support head 11, and is formed on the front surface of the base 13 of the support head 11. The outer contour of the aforementioned rotation stopper 26 is displaced slightly inward along the circumference with respect to the inner contour of the receiving part 23 of the mounting head 19, so that there is a gap between these two contours. There are several millimeters of air gap.

  When torque is applied to the support head 11 by the motor drive device 5, the radial damping member 16 that is securely engaged with the support head 11 and the mounting head 19 is compressed in the circumferential direction, and a reaction force is generated. As a result, the motor drive device 5 is mounted in a non-rotatable manner and is reliably realized to be attenuated by the radial attenuation member 16 and the axial attenuation member 17. These damping members reliably insulate the holding bracket 1 and the tent curtain shaft 3 from any vibration from the motor drive 5. If for some reason the torque applied by the motor drive 5 reaches such a value as to cause excessive compression of the radial damping member 16, after the rotation stopper 26 has rotated by a certain angle The radial attenuating member 16 is not further compressed by abutting against the inner contour of the receiving portion 23 of the mounting head 19. In that case, the support head 11 is supported by the direct attachment head 19. This process also occurs when the radial damping member 16 becomes porous over time and loses its structure over time.

  Finally, it should be noted that the vibration isolator 50 according to the invention can also be arranged between the drive plate 8 and the tent curtain shaft 3 in a similar design.
