Description

cantilever parasol

Technical area

The invention relates to a free-arm umbrella according to the preamble of claim 1.

State of the art

A Freiarmschirm of the aforementioned type is known from EP 0 830 074 B. As a locking device is a split bearing ring of the bearing, on the one hand, the end of the arm is rotatably mounted and on the other hand, the support member is hinged, which in turn is articulated on the mast. To lock the bearing ring is clamped by means of a clamping screw with the boom. A transverse to the boom projecting handle is used to pivot the boom about its axis. The disadvantage is that both the handle and the clamping screw are arranged relatively high above the ground and therefore the accessibility and handling is difficult especially for small people. Moreover, two hands are required to operate and the pivoting of the boom about its axis by means of the handle requires a relatively large force. Finally, the handle projecting transversely to the boom is bulky and makes it difficult to pack the free-arm umbrella for its transport.

From WO2005 / 018369 a free-arm screen is known, in which a cantilever is supported on one end by a bearing on a sliding sleeve displaceable along the mast and on the other hand carries a screen at its free end. In the area between the bearing and the screen, the boom is supported by means of a support element on the upper part of the mast. By moving the sliding sleeve along the mast down, the boom can be folded against the mast. The boom is mounted on the bearing and at the junction of the support member pivotally about its axis. The boom is provided with a handlebar which cooperates with a coupling device and allows locking of the boom in different angles of rotation relative to the bearing. The handlebar is lockable on the mast. The free Although umbrella is easy to handle, since the sliding sleeve and the handlebar are relatively low, but the operation must be done from the inside of the screen, which is cumbersome and associated with the risk of injury. In the folded state, the free-arm screen has a large overall height, which makes the transport of the free-arm parachute in the packed as well as unwrapped state, in particular for transport in passenger cars, very difficult.

From DE 299 06 116 Ul a Freiarmschirm with a mast is known in which is hung on a boom at the top of the screen. The boom is guided axially displaceably in a pivoting guide on the mast. With a handle, the boom can be moved axially in the pivot guide. The boom is provided with a rack which cooperates with a pinion in the pivot guide and serves to lock the extended position of the boom. Thus, it is not possible to pivot the boom in the pivot guide about its axis. For pivoting the screen about the axis of the boom of the screen is arranged on a boom part which is pivotally mounted in the arm about the axis of the boom. To determine the boom part with respect to the boom is a clamping cone in the boom part, which cooperates with a clamping cone in the boom. The clamping cones can be braced against each other by means of a screw spindle. The fact that only the boom part is pivotally mounted in the boom, there is a labile, trouble-prone storage of the boom part, which is also difficult to access because of their arrangement near the crown. ^■ •

Presentation of the invention

The object of the invention is to improve a Freiarmschirm of the type mentioned.

The object is achieved by the characterizing features of claim 1. The fact that the locking device has an extension of the boom lying, bendable against the support member steering rod, on the one hand locked with the support member and on the other hand in the unlocked state to the Axis of the boom is pivotable and is detachably coupled by means of a coupling device in selectable angles of rotation relative to the boom with the boom, the necessary functions and settings for the Freiarmschirm can be easily and easily perform. The handlebar moves the accessibility of the controls to a lower height from the ground, making them accessible to smaller people. Moreover, the controls are on the outside of the screen, making the operation more convenient and safer against accident. Due to the given by the handlebar lever arm, the pivoting of the boom about its axis is easier and easier. Since the handlebar on the one hand serves to pivot the boom about its axis and on the other hand to lock the pivot position by locking the handlebar to the support element, there is a significant simplification of the operation, which can also be performed with one hand. But the handlebar also serves to extend and retract the boom along its axis, whereby this function of Freiarmschirmes. simplified and facilitated.

Advantageous embodiments of the Freiarmschirmes are described in claims 2 to 12.

Particularly advantageous is the embodiment according to claim 2, according to which the bearing is arranged for the end of the boom in a housing on which on the one hand the support member is articulated and on the other hand, a handlebar supporting the housing part is pivotally mounted about the axis of the boom and in which the coupling device is arranged. As a result, the sensitive parts of the Freiarmschirmes are arranged in a housing which protects the sensitive parts on the one hand from contamination and on the other hand also serves the functional safety and accident prevention. It is thus virtually impossible that an operator may be injured when handling the screen.

Particularly advantageous is the further embodiment of the Freiarmschirmes according to claim 3, according to which the coupling device comprises a first coupling part, but non-rotatably displaceable in the direction of the axis of the boom. bar is arranged at the end of the boom. By means of a spring, the coupling part is biased against a second coupling part, which is connected to the steering rod in a manner secure against rotation. The first coupling part is associated with a pressure piece which can be actuated for releasing the coupling device by means of a cam part on the handlebar when it is swung in a Entkupplungsbereich. Different areas are conceivable for the decoupling area. It is advantageous if the Entkupplungsbereich the handlebar according to claim 4 between the locking position of the handlebar on the support member and extending in the axial direction of the boom stretched position is. Then a disengagement and engagement of the handlebar is given to the boom in good operating height. It is particularly advantageous if, according to claim 5, the steering rod on both sides of the curve part has support surfaces which cooperate with the pressure piece to temporarily fix the handlebar in the positions on both sides of the curve part. , , , ... ,

For the coupling device, there are a variety of design options, from the non-positive to the form-fitting design of the coupling. The frictional training allows a great fine adjustment, but requires a relatively large bias of the coupling parts against each other. Therefore, an embodiment of the coupling device according to claim 6 is advantageous, after which this is positively formed and preferably as a toothed coupling.

In order to avoid malfunction of the free-arm screen, it is advantageous if the boom according to claim 7 has a pivoting angle which is preferably limited by stops.

The function of the Freiarmschirmes is further substantially improved by the formation of the free-arm screen according to claim 8, wherein the boom and the handlebar for guiding a pulling member for opening and closing the screen are hollow. In particular, the embodiment according to claim 9 is advantageous, according to which at the free end of the handlebar a winch for the tension member is present, by means of which the screen can be opened and closed.

The locking of the handlebar to the support element is carried out according to claim 10, preferably by means of a clip, whereby the handlebars on the one hand quickly and easily locked and on the other hand just as quickly and easily the lock can be solved again.

To prevent accidental extension of the boom, the development of Freiarmschirmes claim 11 is advantageous. In this case, the boom is latched in its extended position by means of a detent, which can be solved by means of a release member by hand again. The Freiarmschirm with the extendable and retractable boom and the simple combined controls not only allows easy and easy operation of Freiarmschirmes, but finally allows according to claim 12 also a transportable collapsibility to a compact slim package that is so shortened that it especially in a passenger car is transportable.

Ways to carry out the invention

1 shows a Freiarmschirm in its extended position and with the screen open and the figure 2 this Freiarmschirm in the closed and folded position. The Freiarmschirm has a mast 2, which may be anchored in the bottom 4 or a base 6. At the upper end of the mast 2 is on a sliding bearing 8, a boom 10 in its longitudinal direction and retractable and mounted pivotably about its axis. The sliding bearing 8 is pivotally mounted on a mast 9 on the mast 2. At one end of the boom carries a screen 12 and at the other end of the boom 10 is pivotally mounted in a bearing 14 about its axis. The bearing 14 is supported via a support element 16 on the mast 2. For this purpose, the support element 16 is articulated via a joint 18 on the bearing 14 and via a joint 20 on a support sleeve 22 which is arranged on the mast 2. At the bearing 14 there is a locking device 24 for locking the pivoting position of the arm 10 in a selectable pivoting position. For this purpose, the locking device is provided with a lying in the extension of the boom 10 handlebar 26 which is articulated against the support member 16 via a hinge 27. The handlebar is latched by means of a locking device 28 with the support member 16. In unlocked state, the handlebar 26 can be pivoted about the axis of the boom and be detachably coupled by means of a coupling device 30 in selectable angles of rotation relative to the boom with the boom, as can be seen from the following embodiments and figures in detail. The handlebar is then also at oblique screen before accident endangered.

As can be seen from FIG. 3, the arm 10 is locked in the extended position by means of a catch 32, which is pretensioned outwards by a spring 34. By means of a release member 36, by means of a push rod 38 and a not shown handle from an advantageous operating height can be operated, the catch 32 can be pressed against the force of the spring 34, after which the boom 10 in the axial direction in the retracted position shown in Figure 2 can be moved.

The boom 10 and the handlebar 26 are hollow and designed to receive a tension member 40 preferably a rope, which allows in a manner not shown, but known manner, the opening and closing of the screen. In the region of the joint 27 of the handlebar 26 on the bearing 14, a deflecting member 44 is present, which deflects the tension member 40 from the boom 10 in the handlebar 26 and leads to a arranged at the end of the handlebar winch 46. By means of a hand crank 48, the tension member 40 can be wound up to open the screen 12 and unwound to close the screen. A clip 50 of the locking device 24 is also arranged on the housing of the winch 46, as can be seen in particular from FIG.

Figures 5 to 9 show the formation of the bearing 14 and the design of the handlebar 26 and the coupling device 30 and their function in detail, the extension and retraction of the boom, the opening and closing of the screen and its inclination to a combined control point in preferred operating height is brought together outside the screen.

The bearing 14 is provided with a housing 52 which is divided in its longitudinal direction and consists of the housing halves 52a and 52b. On the boom 10 bearing rings 54 56 are arranged, which are mounted in corresponding bearing rings 58 60 of the housing 52. At the end of the boom 10, a sleeve 62 is slidably mounted in the axial direction of the arm in this. Grooves 64 on the outside of the sleeve 62 and springs 66 on the inside of the boom 10 ensure a rotationally secure guidance of the sleeve 62 in the boom. A bolt 70 disposed in bores 68 of the boom engages a longitudinal slot 72 in the sleeve 62 and limits the axial displacement of the sleeve 62. A compression spring 74 rests on the bolt 70 and serves to bias the sleeve 62 against the handlebar assembly. The sleeve 62 carries a radially standing cam 76 which cooperates with stops 78 in the housing 52 and limits the pivot angle of the boom 10 about its axis. Of the stops 78, only one is shown in the housing half 52a. An analog stop is also present in the housing half 52b.

The sleeve 62 is part of the coupling device 30 and includes a first coupling part 80 which cooperates with a second coupling part 82 which is associated with the handlebar 26. The coupling parts 80,82 may be formed positive or non-positive. In the present example, it is a positive coupling device with sprockets having coupling parts 80,82.

The second coupling part 82 is connected against rotation with the handlebar 26. For this purpose, the second coupling part 82 is arranged in a handle part 84 carrying the handlebar 26, which is mounted in the housing 52 so as to be pivotable about the axis of the arm 10 by means of a bearing 85. The handlebar 26 is further pivoted about the aligned transversely to the axis of the boom joint 27. The handlebar 26 has an opening of the coupling device 30 causing the cam member 86 which cooperates with a pressure piece 88 which is mounted on a flange 90 of the sleeve 62 which carries the first coupling part 80. On both sides of the cam member 86, the handlebar 26 has support surfaces 92, 94 which cooperate with the pressure piece 88 and the handlebar 26 in the pivoted-in or swung-out position of Figures 7 and 9 releasably hold.

5 shows the handlebar 26 in the latched state in which the clip 50 of the latching device 28 is latched to the support member 16, so that a pivoting of the handlebar 26 is not possible about the axis of the boom 10 about the axis of the joint 27. The first coupling part 80 and the second coupling part 82 are locked in this state, so that a pivoting of the arm about its axis and thus the screen is no longer possible. FIG. 7 shows the handlebar 26 in the unlatched state, so that the handlebars are pivotable about the axis of the arm. Since the coupling parts 80 82 are engaged, so at the same time the boom can be pivoted about its axis.

To lock the boom in a selected pivot position, the handlebar 26 must first be swung in the Entkupplungsbereich shown in Figure 8 by the cam member 86, the pressure member 88 against the force of the spring 66 so far shifts until the first coupling member 80 and the second Clutch part 82 are disengaged, as shown in Figure 8.

In this uncoupling position, the handlebar 26 can first be pivoted freely about the axis of the boom, in an angle which is to correspond to the later desired pivot angle of the boom and thus the desired inclination of the screen 12. Then, the handlebar is pivoted back in this pivoted position against the support member and thereby brought the coupling parts 80 and 82 into engagement. Now, by pivoting back the handlebar 26 parallel to the support member 16 of the boom and thus the screen can be brought into the previously desired pivot position. By latching the handlebar 26 by means of the latching device 28 with the support member 16 analogous to the position of Figure 2 and 5, the pivotal position of the boom 10 and thus of the screen 12 is then secured. The latched to the support member 16 handlebar 26 is thus no longer dangerous across the boom away. The pivoting back of the arm 10 and thus of the screen 12 in the basic position shown in Figure 1 takes place in the reverse order of operations.

FIG. 9 shows the handlebar 26 in a position in which it practically corresponds to the extension of the arm 10. The cooperating with the pressure piece 88 support surface 96 holds the handlebar 26 in the extended position. In this position, the coupling parts are engaged. This position is used primarily for extending and retracting the boom in the axial direction and the space-saving folding the Freiarmschirmes (Figures 2 and 11). Figures 10 and 11 show the Freiarmschirm in collapsed and partially disassembled form in a packaging container 96, which serves in particular for the transport and possibly also for the storage of Freiarmschirmes. The screen 12 is removed from the boom 10 and the mast 2 divided into two parts 2a and 2b, which are telescopically plugged into each other. The boom 10, which may also consist of telescopically assembled parts is inserted with the disassembled mast 2 and the support member 16 and the handlebar 26 in the lower part of the packaging container 96, as shown in Figure 10. The collapsed screen 12 is placed over it in a second position, as can be seen in FIG. If appropriate, the screen can also be connected to the boom in an articulated manner, so that there is no need for removal and the umbrella can be inserted into the packaging container together with the delivery arm. Thus, even a relatively large Freiarmschirm compactly folded and transported in a small space, so that maximum mass, which are currently at a length of 2 meters; for transport by post and / or in a passenger car. The compact packaging also minimizes the risk of damage during transport.

The new free-arm screen shows quite decisive advantages. The operating elements for extending and retracting the boom, opening and closing and

Tilting of the screen are also at large umbrellas at comfortable operating height and outside the screen. The extension, opening and tilting as well as locking in the inclined position is summarized in a single operating unit, which is given by the handlebar with the winch. The opening and closing of the screen and the extension of the boom can be done simultaneously or independently.

The squat design of the free-arm umbrella on the one hand and the fixation of the joints also results in increased stability and wind stability.

The sensitive drive parts of the free-arm umbrella, in particular the coupling device and the active parts of the handlebar, are housed in a housing which protects them on the one hand from contamination and weather influences and on the other hand protects the operator from injury hazards. In addition, the housing allows a rounded design of the free-arm umbrella, which not only improves the appearance of the free-arm screen, but also reduces the risk of injury.

The pivoting of the boom and thus the tilting of the screen causes only an insignificant change in the tension of the tension member, such as the rope when the screen is open.
