Description

[0001] The present invention relates to a standing umbrella, in particular a parasol, comprising an immersion tube, with an electric motor according to claim 1, wherein the tensioning frame is adjustable by translationally adjusting the immersion tube between a tensioned position that stretches the roof skin and a relaxed closed position, and adjusting means comprising an electric motor for telescopically adjusting the immersion tube in the standing tube. Furthermore, the invention relates to a system according to claim 10.

[0002] Standing umbrellas with a telescopic system (submersible tube umbrellas) are generally known as sun protection in the form of common and commercially available parasol devices. With submersible tube umbrellas, a tensioned frame is opened by telescopically inserting a submersible tube into a standpipe. This shortens the overall height of the standing umbrella (composed of the standpipe and submersible tube) and adjusts the tensioned frame to a tensioned position that spans the roof covering. The stretched roof covering creates an area underneath that is protected from direct sunlight and precipitation. In DE 20 2005 011 579 U1, the applicant has already described an embodiment of a standing umbrella based on a telescopic system comprising a spindle drive.

[0003] The aforementioned free-standing umbrellas are widely used in both private and commercial settings. The telescopic system is particularly suitable for large free-standing umbrellas with large tensioned frames, as it maintains a large clearance from the ground when opening and closing the frame. This eliminates the need to clear surrounding tables and chairs before closing the free-standing umbrella. This is a huge convenience in the restaurant industry and also allows for multiple adjustments of the telescopic tube umbrellas, even when the restaurant is operating simultaneously.

[0004] Also well known are submersible tube umbrellas that can be manually adjusted between an open, tensioned position and a relaxed, closed position using a hand crank. There are also submersible tube umbrellas that do not have a manually operated crank mechanism and are adjusted using an electric motor located within the standpipe, which automatically adjusts the tensioning frame at the push of a button. The motor shaft of the electric motor is axially aligned with a spindle of a spindle drive, to which the motor shaft is firmly coupled and torque-transmitting. Disadvantages of this actually convenient concept arise if the electric motor fails, as the umbrella can then no longer be adjusted.This is particularly problematic if the umbrella is partially or fully open when the motor fails, as the canopy provides a surface for wind load, which can further damage or even completely destroy the umbrella. Repairing the motors discreetly integrated into the standpipe is also complex, as the electric motor is only accessible from below. To access the motor, the stand umbrella must first be tilted over, which is further complicated by the tensioning frame protruding from the side when the umbrella is partially or fully open.

[0005] DE 201 18 472 U1 teaches a standing umbrella, in particular a large umbrella, consisting of a straight standpipe in which a reversible motor, which can be switched on and off with a power source, is arranged, with an actuator for opening and closing the adjustment mechanism of the umbrella roof, which can be folded and tensioned by means of umbrella roof spokes.

[0006] DE 44 47 341 A1 discloses a weather protection device comprising a cover that can be opened and folded when closed, and can be used like an umbrella or awning. On the support, which is normally arranged approximately vertically, rods supporting the cover are provided that can pivot around an axis arranged at right angles to this support and at a short distance from it.

[0007] DE 10 2010 020 397 A1 relates to a standing umbrella comprising a base and a frame with a mast and a foldable rod for supporting a top covering, in particular for the purpose of shading the sunlight.

[0008] DE 20 2009 017 573 U1 relates to a telescopic mast umbrella with a gear construction which serves to open and close umbrellas and simultaneously locks and secures the open and closed state.

[0009] DE 20 2005 011 579 U1 relates to an umbrella, in particular a parasol, with a tensioning frame mounted on a standpipe, which frame contains support arms for a covering - in particular a roof skin - which are radially hinged to a ridge plate or similar bearing element, as well as support spokes hinged at both ends between these and at least one sliding ring movably guided on the standpipe as the lower bearing element.

[0010] Based on the aforementioned prior art, the object of the invention is to provide an electrically operated parasol in which the electric motor is easily accessible and replaceable in the event of a failure, while eliminating the need to tilt the parasol. It would also be preferable if the parasol could be adjusted even after the electric motor fails.

[0011] This object is achieved by the standing umbrella having the features of claim 1.

[0012] Furthermore, protection is claimed within the scope of the invention for a system having the features of claim 9.

[0013] In a manner advantageous according to the invention, the standing umbrella comprises a tensioning frame comprising an immersion tube for tensioning a roof skin, in which the tensioning frame can be adjusted by translationally adjusting the immersion tube between a tensioned position tensioning the roof skin and a relaxed closed position. For comfortable operation, the standing umbrella comprises an electric motor which is arranged according to the invention on the outer circumference of the standpipe, in particular on a support plate, and is mechanically coupled to the adjusting means via operative connection means through a lateral opening in the standpipe. The mechanical coupling provided according to the invention of the electric motor arranged on the outer circumference with the adjusting means via the operative connection means enables the tensioning frame to be adjusted by operating the externally arranged electric motor.Furthermore, the inventive arrangement of the electric motor on the outer circumference of the standpipe, in particular on a support plate, provides direct and easy access to the electric motor and the active connection means, eliminating the need to flip the parasol for maintenance and repair work or even to replace the electric motor. Furthermore, the parasol can also be operated manually using active connection means that are at least partially accessible from the outside and by coupling a hand crank to the active connection means, or alternatively, directly with the internal coupling gear through the lateral opening in the standpipe. The parasol, comprising the electric motor and active connection means, preferably has a modular design.

[0014] The tensioning frame, which is adjustable relative to the standpipe, preferably comprises support elements that are mounted radially and pivotably on the immersion tube or another fixing element, such as a retaining ring, and supported by support spokes. The support spokes, in turn, are preferably mounted radially and pivotably directly on the standpipe or another fixing element, such as a retaining ring, on the standpipe and on the support element. The translational displacement of the immersion tube leads to an unfolding of the support elements, which are then supported by the support spokes. The roof skin is tensioned by the radially pivoting support elements. The tensioning frame is preferably adjusted from the relaxed closed position to the clamping open position by telescopically sliding the immersion tube into the standpipe. This creates a shaded area underneath that is protected from direct sunlight and precipitation.

[0015] Furthermore, the telescopic or immersion tube system enables collision protection with objects arranged underneath, in particular with glasses and bottles placed on tables, since when the clamping frame is adjusted to the relaxed closed position, a large distance is maintained between the elements, in particular the support elements, of the clamping frame and the floor or the table tops.

[0016] In a preferred embodiment of the invention, the adjustment means arranged in the standpipe for translationally adjusting the immersion tube have a spindle drive. The spindle drive preferably comprises a rotatable and stationary spindle with a spindle nut that is connected to the immersion tube in a rotationally fixed manner and can be translationally adjusted by rotating the spindle together with the immersion tube, as well as an internal coupling gear, which is preferably designed as an internal angular gear. The internal coupling gear is preferably designed like the crank gear previously used exclusively for manually operated standing umbrellas, which now, instead of a crank, is detachably adjustable, in particular mountable without tools, via the torque-transmitting active connection means connected to the electric motor, in particular via a connecting shaft to be explained later.The coupling gear arranged in the standpipe serves to convert a rotational movement from the active connection means into a rotation of a spindle drive component, in particular the spindle, at an angle, in particular a right angle. The rotationally fixed connection between the immersion tube and the spindle nut is preferably designed such that the spindle nut can be adjusted translationally when the spindle rotates. Since the spindle nut and the immersion tube are mechanically coupled in a rotationally fixed manner, this allows the conversion of a rotational movement into a purely translational adjustment movement.

[0017] The inner coupling gear is preferably designed as a crown gear or bevel gear, whereby an angular, in particular right-angled, non-positive coupling between the active connection means and a spindle drive component, in particular the spindle, is enabled.

[0018] Alternatively, the spindle in the standpipe can be arranged not fixed but translationally adjustable, but not rotatable, and can be mechanically coupled to the immersion tube by means of the stationary and rotatable spindle nut in such a way that the immersion tube can be translationally adjusted without rotation. In this case, the inner coupling gear preferably drives the stationary spindle nut in rotation.

[0019] According to the invention, the motor shaft of the electric motor is arranged parallel to the longitudinal extension of the immersion tube, and the operative connection means comprise a detachable angular gear arranged outside the standpipe for transmitting an electromotive drive torque from the motor shaft to the adjustment means. In particular, angular, preferably right-angled, angular gears based on a crown or coupling gear pair are preferred, or are preferably designed as a crown thread or coupling thread. For a low number of components and the associated cost savings, the advantageous use of the same angular gear as for the adjustment means is preferred (internal angular gear).

[0020] In a further development, the inner coupling gear of the adjustment means arranged inside the standpipe is coupled to the outer angular gear of the active connection means arranged outside the standpipe by a connecting shaft arranged perpendicular to the motor shaft and also perpendicular to the longitudinal extent of the standpipe in a force-locking, in particular form-locking, manner. The mechanical coupling enables the transmission of the torque generated by the electric motor of the motor shaft to the spindle drive of the adjustment means. An advantage of the embodiment according to the invention is the good accessibility of the mechanical components. Furthermore, manually operated parasols can be retrofitted to electric motor operation thanks to the inventive arrangement of the electric motor on the outer circumference of the standpipe and the now advantageous coupling of the adjustment means by the connecting shaft.

[0021] A particularly preferred embodiment of the invention is one in which the clamping frame surrounding the immersion tube is designed such that the total force acting on the immersion tube upon adjustment of the clamping frame comprises mutually balancing partial forces, by means of which the clamping frame can be positioned at rest at any intermediate position during translational adjustment of the immersion tube. This advantageously enables the electric motor arranged on the outer circumference of the standpipe, according to the invention, to be designed to be small, despite a large clamping frame with long and heavy support elements. In addition, a constant load is exerted on the active connection means, the adjustment means, and the electric motor throughout the entire adjustment process of the clamping frame, which has a beneficial effect on the service life of the immersion tube umbrella.Synergistically, this reduces the number of components by reusing the same components (angle gears), allowing the same electric motor to be used for different sized submersible tube umbrellas, promising additional cost savings. Alternatively, the clamping frame can also be designed to generate weight-induced opening or closing forces.

[0022] Furthermore, a preferred embodiment of the immersion tube umbrella according to the invention offers the possibility of routing the cables for the electric motor inside the standpipe and leading them through a lateral opening on the outer circumference of the standpipe or through the same lateral opening as the active connection means to the electric motor. This ensures a visually high-quality design, as the cable runs unobtrusively inside the standpipe. Furthermore, routing the cable inside the standpipe prevents tripping hazards and makes unauthorized access difficult, for example, in the event of vandalism, as well as protecting the cable from the elements.

[0023] As a further development and advantage, it is provided that, for a visually appealing design of the immersion tube umbrella according to the invention, the electric motor and the active connection means are also enclosed in an outer housing. The outer housing is preferably arranged on the support plate with a seal or encloses it. The outer housing preferably extends along the standpipe and also provides protection against injury to body parts such as fingers, as accessibility to rotating parts is thus not provided. In addition, the outer housing protects the electronics arranged underneath and the mechanics used for coupling from moisture and dirt. Advantageously, the outer housing is also preferably arranged at a height on the standpipe which, in the relaxed closed position of the stand umbrella, lies behind the roof skin, whereby the roof skin advantageously enables additional protection against moisture, particularly from precipitation.Preferably, the electric motor is mounted on the standpipe at a height of between 1 m and 1.8 m from the ground, which makes the electric motor easily accessible for maintenance and repair work.

[0024] It is also particularly expedient if, in a further development of the invention, the adjusting means of the submersible tube umbrella can also be operated manually via a hand crank for tensioning and / or relaxing the roof skin. It is preferred if the hand crank can be adjusted by force-fitting, in particular form-fitting, coupling to the motor shaft of the electric motor arranged according to the invention on the outer circumference of the standpipe, by force-fitting, in particular form-fitting, coupling to the inner coupling gear of the adjusting means by completely removing the active connection means, or by force-fitting, in particular form-fitting, coupling of the connecting shaft by partially removing the active connection means. This advantageously makes it possible to adjust the tensioning frame of the submersible tube umbrella even if the electric motor fails.This can be combined synergistically with the inventive arrangement of the electric motor comprising the operative connection means on the outer circumference of the standpipe, since operative connection means are provided for coupling the electric motor with the adjusting means, which are guided through an opening in the outer circumference of the standpipe and which can also be converted for manual operation by means of a hand crank with little technical effort.

[0025] Furthermore, a preferred embodiment of the immersion tube umbrella according to the invention offers the possibility of the electric motor arranged on the outer circumference of the standpipe comprising, preferably wireless, communication means designed such that control signals can be received, which can preferably be implemented via motor control means for controlling the electric motor for opening and / or closing. Furthermore, it is particularly preferred if the wireless communication means are based on standardized radio protocols comprising radio technology, since this enables the transmission of control signals even over long ranges and the radio signals can also penetrate walls. The preferred control by means of radio technology, even from a great distance, is synergistically supported by the telescopic system, since no manual preparatory work is required before closing the tensioning frame due to the large ground clearance of the support elements.In addition, people sitting under the dip tube umbrella or glasses and bottles standing on tables underneath do not collide with the support elements or the roof skin when the tensioning frame is opened and closed.

[0026] While in the context of the present invention, protection is claimed in principle for the immersion tube umbrella according to the invention, protection is also claimed within the context of a system claim for an immersion tube umbrella according to the invention and a further component.

[0027] Preferably, the further component is formed by wind speed detection means designed to detect the wind speed at the location of the standing umbrella, in particular via an anemometer arranged at the free end of the immersion tube. This allows the determination of the wind load acting on the unfolded immersion tube umbrella. In a further development, the wind speed detection means are designed to automatically generate a control signal via communication means for adjusting the tensioning frame of the standing umbrella to a relaxed closed position when a definable wind load limit is exceeded and / or for adjusting the tensioning frame to an open tensioning position when a definable wind load limit is undershot. In addition, the wind speed can be sent to a control unit, in particular via radio technology, either continuously or only when a definable wind speed threshold is reached.A wireless connection, particularly based on the widely used Wi-Fi protocol, is particularly preferred, as it enables reception on commercially available mobile tablet computers and other mobile computing devices. The advantageous use of such a wireless protocol also allows the control of the adjustment mechanisms of one or more immersion tube umbrellas via such a mobile computing device. Public network access is also possible, allowing users, especially visitors to a restaurant, free internet access via the Wi-Fi protocol.

[0028] A preferred embodiment is one in which the additional component is formed by a central control unit. The central control unit is preferably designed as a battery-operated radio remote control and is suitable for generating control signals for tensioning and / or relaxing the roof skin by adjusting the adjustment means by controlling the electric motor comprising the motor control means and communication means.

[0029] In a further development, the additional component can be formed by a hand crank, by means of which manual adjustment of the clamping frame is possible. It is preferred if the hand crank is coupled to the motor shaft of the electric motor via a connection point in a force-fitting, in particular form-fitting, manner. However, a mechanical coupling of the hand crank to the outer bevel gear is also conceivable, wherein the electric motor has been dismantled beforehand. Alternatively, a force-fitting, in particular form-fitting, mechanical coupling of the hand crank to the active connection means can also be achieved by coupling the hand crank to the connecting shaft, wherein the outer bevel gear is dismantled beforehand. Alternatively, a mechanical coupling between the hand crank and the inner coupling gear is also conceivable, which is preceded by the tool-free dismantling of the active connection means.All of these designs allow the umbrella to be adjusted manually by adjusting the adjustment devices, even if the electric motor fails.

[0030] However, the protection of the invention is not limited to this type of system; rather, as a further development, it is also provided and encompassed by the present invention that a system is formed from several submersible tube umbrellas which can be controlled jointly or individually, i.e. independently of one another, via a central control unit to adjust the tensioning frame between a relaxed closed position and an open tensioning position, in which an area protected from direct sunlight is created under the roof skin. The control of a standing umbrella is preferably carried out by a digital radio signal which can be received by all standing umbrellas and which can then be addressed for a specific standing umbrella using specific bits. This allows the individual control of one umbrella or the joint control of all umbrellas. The joint control is implemented by a specific address (broadcast).It is also planned that the protected area will be combined by several submersible tube umbrellas in order to shade a large area, for example in a beer garden.

[0031] In addition, a system is planned in which the motor control is designed as a central unit and then takes over the control of several parasols.

[0032] As a result, the stand umbrella according to the invention enables comfortable operation thanks to the electric motor arranged on the outer circumference of the stand tube. The tensioning frame can be adjusted fully automatically at the push of a button between a relaxed closed position and an open tensioning position, while the electric motor still remains easily accessible for maintenance and service work. The high level of operating comfort is synergistically enhanced by the fact that, even in the event of a failure of the electric motor, the stand tube umbrella can be adjusted using a hand crank. Furthermore, to create a visually high-quality impression, the electric motor and the active connecting elements are arranged behind an outer housing, preferably made using injection molding technology, which synergistically also protects the components of the electric motor and the rotating mechanical components from dirt and splash water.In addition, the cables are to be laid inside the standpipe, which is then fed to the electric motor through a side opening in the standpipe.

[0033] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings.

[0034] These show in: Fig. 1 a schematic side view of a preferred embodiment of the inventive stand umbrella with partially shown tension frame in a relaxed closed position and a greatly simplified electric motor, in Fig. 2 a standing umbrella according to Fig. 1 in a clamping position that stretches the roof skin and in Fig. 3 a perspective partial view of the standpipe with the electric motor arranged on a support plate Fig. 4a - 4c various perspective views of preferred embodiments for coupling the adjusting means arranged in the standpipe with a hand crank for manual adjustment of the clamping frame.

[0035] In the figures, elements and assemblies that are functionally identical or similar are identified by the same reference symbols.

[0036] Fig. 1 shows a stand umbrella (dip tube umbrella) 1 comprising a dip tube system in a relaxed closed position. The total height of the dip tube umbrella 1 is formed by the stand tube 2 and the dip tube 3 arranged thereon. The dip tube 3 can be telescopically moved into the stand tube 2, which is made possible by adjustment means 4 arranged in the stand tube 2. The adjustment means 4 comprise a spindle drive 5, which is formed from a rotatable and stationary spindle 6 and a spindle nut 7 that is translationally adjustable with the dip tube 2 in a rotationally fixed manner. The spindle nut 7 is mechanically coupled to the dip tube 3 in such a rotationally fixed manner that the rotation of the spindle nut 7 leads to the translational displacement of the dip tube 3.The tensioning frame 8 is arranged on the standpipe 2 and immersion tube 3 in such a way that by shortening the overall height by telescopically sliding the immersion tube 3 into the standpipe 2, the tensioning frame 8 is unfolded on the circumference of the standpipe 2, whereby the roof skin 9 is tensioned by the tensioning frame 8. The tensioning frame 8 comprises support elements 10 arranged pivotably on the immersion tube 3 via a first joint element 27, as well as support elements 11 which are pivotally arranged on the immersion tube 3 at one end via a second joint element 28 and are pivotally connected to the support elements 12 at the opposite second end at an intermediate section of the support elements 12 via a third joint element 29. The electric motor 15 is arranged on the outer circumference of the standpipe 2 on a support plate 14 fixed to the standpipe and is non-positively connected to the adjusting means 4 via operative connection means 16.The operative connection means 16 comprise an outer angular gear 17 for the right-angle conversion of a rotary movement and a connecting shaft 18 for the frictional transmission of the rotary movement to an inner coupling gear 19 of the adjustment means 4, which is coupled to the spindle 6 of the spindle drive in a torque-transmitting manner. The outer angular gear 17 of the operative connection means 16 consists of a coupling through a bevel gear pair. The bevel gear pair converts the torque of the motor shaft 18 of the electric motor 15, which is arranged parallel to the longitudinal extension of the standpipe 2, to the connecting shaft 20, which is arranged perpendicular to the longitudinal extension of the standpipe 2 and is guided through an opening 24 in the outer circumference of the standpipe 2.In the standpipe 2, the torque of the connecting shaft 20 is converted into a rotational movement of the spindle 6 by the inner coupling gear 19 of the adjusting means 4 arranged in the standpipe 2.

[0037] In Fig. 2 is the Fig. 1 shows an embodiment of the standpipe umbrella 1 according to the invention with the tensioning frame 8 open. To open the tensioning frame 8, the immersion tube 3 is translated into the standpipe 2 by the adjustment means 4, whereby the tensioning frame 8 formed by the support elements 10 and the support elements 11 is adjusted from the relaxed closed position to the open tensioning position. The roof skin 9 is thereby stretched by the support elements 10, creating an area underneath that is protected from precipitation and direct sunlight.

[0038] During operation, the electric motor 15 arranged on the outer circumference of the standpipe 2 generates a torque which is initially transferred to the connecting shaft 20 of the active connecting means 16 by the outer coupling gear 17 of the active connecting means 16. The connecting shaft 20 is guided through a lateral opening in the outer circumference of the standpipe 2 to the adjustment means 4 arranged in the standpipe 2. In the standpipe 2, the torque is then transmitted by the connecting shaft 20 to the inner coupling gear 19, through which the rotary movement is non-positively transmitted to the spindle drive 5 arranged in the standpipe 2. The rotation causes the stationary spindle 6 arranged in the standpipe 2 to rotate, whereby a spindle nut 7 arranged thereon, which is connected in a rotationally fixed manner to the immersion tube 3, is translated.By telescopically sliding the immersion tube 3 into the standpipe 2 by means of the adjusting means 4, the clamping frame 8 is clamped, since the carrier elements 10 are pivotably arranged on the circumferential side of the immersion tube 3 and the standpipe 2, supported by the support elements 11.

[0039] Fig. Figure 3 shows the electric motor 15, which is mounted on the support plate 10 by means of connecting elements 25, and whose rotor is arranged parallel to the longitudinal extension of the standpipe 2. The motor 15 and the active connection means 16, shown here in a highly simplified manner, are arranged in the surrounding housing 13 and are thus protected from dirt and moisture. Furthermore, a seal 26 is provided between the surrounding housing 13 and the support plate 10, which also seals the connection point and protects the electric motor 15 and the active connection means 16 from environmental influences.

[0040] The Fig. 4a, Fig. 4b and Fig. 4c each show a different embodiment of the immersion tube umbrella 1 with the advantageous manual adjustment of the clamping frame 8 by means of a hand crank 21.

[0041] In Fig. 4a, for manual adjustment, a force-locking operative connection between the hand crank 21 and the rotor of the electric motor 15 is implemented by a connection point 22 arranged on the top side of the electric motor 15. For this purpose, an opening 23 is provided in the surrounding housing 13 through which the hand crank 21 can be guided to the electric motor 15, on which a form-locking connection point 22, preferably with a hexagonal structure, is provided on the top side. The crank 21 can be coupled to the motor shaft 18 of the electric motor 15 through the connection point 22, whereby the latter can be rotated manually. By inserting the hand crank 21 into the connection point 22, a safety relay (not shown graphically) is preferably additionally switched in order to disconnect the electric motor 15 from the power supply and to prevent electrical operation of the motor 15 with the crank 21 inserted.By manually rotating the motor 15, the adjusting means 4 are adjusted in the generally usual manner. The direction of the rotational movement of the hand crank 21 determines whether the clamping frame 8 is adjusted to the relaxed closed position or to the clamping position.

[0042] Fig. 4b shows how Fig. 4a, the same section of the immersion tube umbrella 1, however, the electric motor 15 is not shown for clarity. In this preferred embodiment, a positive operative connection is established between the hand crank 21 and the connecting shaft 20 of the operative connecting means 16 for manual adjustment. For this purpose, the outer angular gear 17 of the operative connecting means 16 was removed so that the hand crank 21 can be force-fitted to the connecting shaft 20 instead of the angular gear 17. After the force-fit coupling, the adjusting means 4 can be adjusted by rotating the hand crank 21, whereby the clamping frame 8 can be adjusted. Alternatively, a coupling of the hand crank 21 to the outer angular gear 17 is also possible, whereby the electric motor 15 has been dismantled from the support plate 14 beforehand.

[0043] Finally, Fig. 4c shows a further preferred embodiment for the manual operation of the stand umbrella 1 according to the invention. In this embodiment, the hand crank 21 is guided through the opening in the outer circumference of the stand tube 24 and is connected in a force-locking manner to the inner coupling gear 19. For this purpose, the active connection means 16 are completely removed, i.e., in comparison to Fig. 3b, the connecting shaft 20 was also removed. This variant also allows the adjustment of the adjusting means 4 using the hand crank 21, which allows the clamping frame 8 to be adjusted even if the electric motor 15 is not functioning.
