Description

The invention relates to an umbrella stand comprising one in a horizontal foot plane extending foot and a receiving tube connected to the foot for Inclusion of an umbrella shaft.

Such an umbrella stand can be used to hold an umbrella (e.g. Parasol), which has an elongated umbrella shaft like a standpipe but none has its own foot, to be placed anywhere on the floor. To this The purpose of the umbrella shaft of the umbrella is in the receiving tube of the umbrella stand stuck.

In known umbrella stands, the receiving tube is at least firmly in use connected to the foot and extends vertically from the center of the foot above. On the one hand, the center of the umbrella is always above the center of the foot. Secondly, the screen cannot be tilted, except in the upper area of the A corresponding tilt joint is provided. A way to Inclination of the umbrella, which is particularly desirable with parasols, is therefore only given with a specially designed umbrella.

It is an object of the present invention to have a universally applicable To provide umbrella stands with improved performance characteristics.

This object is achieved by an umbrella stand according to claim 1.

The umbrella stand according to the invention is characterized in that an adjusting device is provided for adjusting the orientation of the receiving tube.

The umbrella stand according to the invention allows the orientation of the umbrella shaft change. So there is a change in location and orientation of the used Possible, even if the screen in question does not Inclination joint. In particular very large screens, e.g. with diameters of 3 m or more, usually do not have a tilt joint because this increases the height Effort and is problematic in terms of stability. In addition, the Construction of a device provided on large umbrellas for opening the Umbrellas are often incompatible with a tilt joint. A change in location and orientation of such screens, in particular an inclination of the screens from the Vertical, is only in connection with the umbrella stand according to the invention enables.

Also in connection with umbrellas that have a tilt joint on the umbrella shaft, The invention offers advantages, because in this case a particularly great freedom in Setting the position and orientation of the screen can be achieved. For example it is through a combined use of the adjustment device of the umbrella stand and the tilt joint of the screen possible, position and orientation of the screen to change almost independently. It can also be an even stronger one Inclination of the umbrella can be achieved than in connection with umbrellas that do not Have inclination joint.

The receiving tube should have an inner diameter of at least 3 cm, preferably 4 up to 7 cm around the umbrella shafts of particularly large umbrellas to be able to record. A locking device that supports the umbrella shaft is also advantageous holds in the receiving tube and preferably also secures against rotation. Such locking devices are known per se and can e.g. than in or on top of that screwed or inserted clamping sleeves formed upper end of the receiving tube his. A locking screw screwed in transversely through the receiving tube can also be used be provided.

The adjustment device can be used for a gradual and / or a continuous Adjustment of the orientation of the receiving tube may be formed. The adjustment device can also change the orientation of the receiving tube in several Directions (e.g. with a ball head bearing). In practice, however, it is often sufficient if the receiving tube is at least along a tube pivot plane can be pivoted, this pivoting exactly in the simplest case takes place in this pipe swivel plane. However, a swivel path is also conceivable runs slightly curved along the pipe swivel plane.

The adjusting device preferably comprises a pivot bearing for pivoting the Receiving tube along a pipe pivot plane and pipe holding means for holding the Pickup tube in a desired tube pivot position.

The pipe holding means serve to hold the receiving pipe in one of at least two possible pipe swivel positions, the number of possible pipe swivel positions can also be unlimited in the sense of continuous pivoting. Although the holding means can be integrated into the swivel bearing, it is over Stability reasons (leverage) preferred, this at a distance from the pivot bearing to arrange. The holding means can hold a stop surface for holding the receiving tube have against which the receiving tube rests. In an inclined position of the This support can take place due to gravity due to the receiving tube.

The orientation of the pipe pivot plane is preferably fixed. In this It is useful if the pipe swivel plane is vertical or slightly opposite the vertical is inclined. However, it is also possible that the adjusting device is designed to change the orientation of the pipe swivel plane, for example by pivoting the pivot bearing mentioned above. This leaves itself in a simple manner by combining the pivot bearing with another Realize pivot bearings, the two pivot bearings being non-parallel pivot axes have. The further pivot bearing can e.g. have a pivot axis that runs in the pipe swivel plane or parallel to the pipe swivel plane.

It is advantageous if at least one connected to the foot, along the Pipe pivoting plane extending guide element for guiding the receiving tube when it is pivoted is provided. This can support the Receiving tube in a direction transverse to the pipe pivot plane and thus possibly one The swivel bearing is relieved. The guide element is also suitable especially as a location for the holding means. The guide element is preferred plate-shaped with a flat side parallel to the pipe swivel plane.

In particular for a (fixed or preset) vertical Pipe pivoting plane, it is advantageous if on each side of the pipe pivoting plane a guide element is provided. This enables a bilateral support of the Receiving tube in the transverse direction of the pipe swivel plane. It can be a spacer part be provided that the two guide elements in the transverse direction against each other supports. This increases the resilience of the two guide elements formed guide structure against tilting of the receiving tube transverse to Pipe swivel plane.

The guide element can be designed as a guide plate, which is at least over the pipe swivel path (and e.g. over a large part of the length of the receiving pipe) extends. However, the guide element is preferred as a plate-shaped guide bow formed the distance from the pivot bearing and at least over the Pipe swivel path of the receiving tube runs, preferably in the area of the upper end of the receiving tube. This leads to a material saving for that Guide element without its function to support the receiving tube is significantly affected. The connection of a guide arch to the foot is particularly stable if the arch is connected to the foot at both ends.

Bogen" im Sinne der Erfindung erfaßt nicht nur Kreisbögen, sondern beliebige, wenigstens abschnittsweise gekrümmt oder eckig verlaufende Bögen.The term

Arch "in the sense of the invention not only encompasses circular arcs, but also any arches that run at least in sections or are angular.

In an umbrella stand with a guide element, it is advantageous if at least one guide element pivot bearing is provided on the foot for pivoting the guide element, preferably about a guide element pivot axis running in the tube pivot plane or parallel to the tube pivot plane. On the one hand, this enables the guide element to follow a pivoting of the pipe pivoting plane. For this purpose, the pivot axis of the guide element pivot bearing should run essentially in the tube pivot plane and orthogonal to the tube pivot axis. Regardless of this, this measure can also take up the space required by the umbrella stand Folding "of the guide element in the area of the foot plane can be reduced when it is not in use and is to be stowed away, for example.

It is advantageous if at least one connected to the foot, transversely to Pipe pivoting plane extending support element for supporting or stabilizing the Guide element is provided against tilting in the transverse direction. At a the mechanical guide element is firmly connected to the foot Strain on this connection is reduced, while with a swivel Guide element this guide element with the help of the support element in the Desired pivoting guide element position can be held or supported. The support element preferably extends orthogonally to the pipe pivot plane.

There can be at least one support element on each side of the pipe pivot plane be provided. The at least one support element can e.g. a single one Support the guide element particularly securely or one of two on both sides of the Support the pipe swivel plane arranged guide elements.

It can be provided that the support element extends from a section of the foot on one side of the pipe swivel plane to a section of the foot extends the opposite side of the pipe pivot plane. It can also Support element can be designed as a support arch, which is at a distance from the pivot bearing runs. This leads to a material saving for the support element, without it Support function significantly impair. With regard to the aesthetics of the Umbrella stand it is preferred to close the support arch (s) in a similar manner design like the one or the guiding sheets. For example, these components both be round, in particular circular.

A support element pivot bearing can be provided on the foot for pivoting the support element about a support element pivot axis, for example by the space required by the umbrella stand To fold down "of the support element into the area of the foot plane when it is not being used. In addition, the holding means can also be arranged on the support element and the orientation of the receiving tube can be adjusted by pivoting the support element.

The holding means can by a locking device attached to the receiving tube be formed for the purpose of locking the receiving tube by friction or Form fit can cooperate with at least one guide element. The locking device preferably has at least one in positive engagement with a recess or a hole of the guide element bring locking pin and a handle by means of which the locking pin from the positive Intervention can be brought. In terms of locking safety it is advantageous if the locking device in the area between two on both sides of the Pipe pivoting plane arranged guide elements is arranged and the friction or Form fit to both guide elements can be made.

The foot can comprise several foot parts connected to one another. Here it is Particularly advantageous if the foot parts are connected to one another in an articulated manner are such that, after folding, all foot parts, possibly even all Components of the umbrella stand, essentially in a common plane extend.

Rolls (e.g. 4 to 6 pieces) can be attached to the underside of the foot that the entire umbrella stand can be moved. Especially when each time around a vertical axis freely swiveling rollers are used, this contributes to Convenience in setting the position and orientation of the screen in question at. It should be particularly emphasized that when using such swivel castors Training of the adjustment device only for pivoting along a pipe pivot plane is sufficient to combine with a rotation of the entire umbrella stand (azimuth adjustment) the orientation of the receiving tube and thus to set the screen completely freely. If the roles used are optionally detectable, so an unintentional procedure or twisting the Umbrella stand can be avoided.

To be added are still some embodiments, the special features of which relate in particular to the realization and arrangement of the pivot bearing. If the adjustment of the umbrella stand a pivot bearing for pivoting the Receiving tube and pipe holding means for holding the receiving tube in one Desired pipe position includes, so the pivot bearing relative to the center of the Foot laterally offset in the direction of the pipe swivel plane and / or relative to the foot sideways, especially in the direction of the pipe pivoting plane, in particular slidable, be arranged. This can be achieved that the inclination of the Umbrella, from which the umbrella stand is likely to tip over, is relatively large because the focus of the overall arrangement remains above the umbrella stand base. For The foot can be additionally strengthened with weights (stones, Plates, etc.). Holding tabs or eyes can also be attached to the foot Passage of screws, pegs, etc. may be provided.

If the swivel bearing is immovably attached near the foot level, so In particular, all of the pipe holding means described above can be insert to hold the receiving tube in a desired swivel position.

If the pivot bearing is displaceably arranged in the vicinity of the foot plane, then Modify the pipe holding means accordingly to ensure their function. To For this purpose, a gradual relocation or a provide continuous but lockable displacement of the pivot bearing.

In order to realize the relocatability of the swivel bearing, any number are required appropriate means. It can be easily moved in discrete steps provide by a positive engagement between the pivot bearing on the one hand and an engaging means of a plurality of engaging means, on the other hand, the are spaced apart along the displacement path at the foot. For Continuous shiftability can be achieved in known arrangements for linear guidance be resorted to.

A further pivot bearing can be pivoted at a distance from the base plane be arranged a receiving tube sleeve through which the receiving tube passes. This pivot bearing can e.g. on a guide element as described above be provided, it being fixed or displaceable along the guide element and can be locked. Alternatively, the further swivel bearing can be operated via or support several support struts against the foot. Structurally simple, yet stable is this support if two support struts are at an angle to the pipe swivel plane be provided on an ongoing basis. The foot ends of these support struts can around an axis orthogonal to the pipe pivot plane can be rotatably received on the foot and / or can be arranged displaceably on the foot for pivoting the receiving tube be, this shift e.g. is guaranteed by means such as Movability of the swivel bearing can be provided (positive locking, pin-pin connection, Guide rail etc.).

Below are some embodiments of umbrella stands according to the invention or components of an umbrella stand according to the invention described, wherein in the embodiments corresponding to each other or components with the same effect are identified by the same reference numbers.

1 shows an example of some umbrella stand feet suitable for an umbrella stand 10 12, which extend as a base plate in a horizontal foot plane to the Umbrella stand 10 to give the required stability. The transverse extent of the For this, the foot is about 80 to 140 cm, preferably 100 to 120 cm, if the Umbrella stand is made essentially of wood. For other materials can however, this extension can be chosen to be correspondingly smaller or larger. The foot 12 can be in one piece (Fig. 1a, b, c, d, f, h) or in several parts (Fig. 1e and g) be composed. With the foot 12 is a receiving tube, not shown in Fig. 1 14 (Fig. 2) for receiving an umbrella shaft (e.g. standpipe) of an umbrella connected, which protrudes upwards and whose orientation is adjustable.

.A pivot bearing 16 allows at least pivoting of the receiving tube 14 along a tube pivot plane 18 (tube pivot path 19), in the case of the example shown in FIG. 1 b additionally along a further tube pivot plane 18

.

3 and 4 show embodiments of simple pivot bearings 16, at which the receiving tube 14 at its lower end by an axle 20 for one Swiveling of the receiving tube 14 along the tube pivot plane 18 is enforced becomes.

In the example of FIG. 3, the axle pin 20 is fastened horizontally to an angle part 22 (e.g. welded), which in turn is screwed to part of the foot 12. This Pivot bearing 16 thus allows the receiving tube 14 to be pivoted in one fixed, vertical pipe swivel plane 18.

In the swivel bearing 16 shown in FIG. 4, the axle pin 20 is held between the legs of a U-shaped part 24, which is supported by a further axle pin 20 is enforced in order to pivot the pivot bearing formed from the axle pin 20 and the part 24 about the axis of the further axle pin 20 to enable. The further axle pin 20 is in turn via an angle part 24 connected to the foot 12. 4 allows the pipe pivot plane 18 to be tilted in the direction of arrow K.

Alternatively, the pivot bearing could also be pivoted about a vertical axis (Azimuth adjustment) by arranging the further Achabolzen vertically or the swivel bearing is attached to a base plate that is above a foot forming bottom plate is arranged and rotatably mounted on this.

The bearings 16 shown in FIGS. 3 and 4 can be known Clamping or latching devices can be provided which the receiving tube in a hold the desired orientation. However, holding means are preferred at a distance from the Swivel bearing provided, for example as described below.

To guide the receiving tube 14 when it is pivoted along the Pipe pivoting plane 18 can be at least one connected to the base 12 Guide element 30 may be provided, e.g. is shown in Fig. 2. The Umbrella stand 10 of FIG. 2a has a tube swivel plane 18 on both sides Guide element 30 designed as a semicircular plate. This guide plate 30 is screwed firmly to the foot 12 in the example shown, but can alternatively also releasably or articulatedly connected to the foot 12. The top view of Fig. 2d illustrates the bilateral support of the receiving tube 14 by the two Guide plates 30.

The umbrella stand 10 shown in Fig. 2b and e has a plate-like and arcuate guide element 30 which at its left end in the figures with the Foot 12 is connected. This umbrella stand 10 is particularly suitable for a large one Inclination of the screen relative to the vertical, since the pivot bearing 16 is off-center is arranged on the base 12 and thus an increased stability of the umbrella stand 10 given a pivoting in Fig. 2b to the left (arrow 19).

The umbrella stand 10 shown in Fig. 2c and f has two on both sides of the Pipe pivoting plane 18 arranged and extending over the pipe pivoting path Guide elements 30, which at their ends for common storage on the foot 12 are interconnected. The example shown also illustrates that the If desired, pivot bearing 16 can be arranged at a distance from the base plane can.

Although it is not shown in FIG. 2, the umbrella stands shown can 10 also one or more support elements for transverse support of the guide element be provided. Such support elements are part of the The following exemplary embodiments are described.

FIG. 5 shows an arrangement of some components that is also preferred with regard to the aesthetics of the umbrella stand. Parts of the foot 12 are shown, two plate-like arcuate guide arches 30 and two plate-like arcuate support arches 40. When using the umbrella stand, the guide arches 30 extend parallel and on both sides of the pipe pivot plane 18 and are each transversely directed by one of the support arches 40 which extend orthogonally to the pipe pivot plane 18 supported. The supporting arches 40 are screwed to the foot 12 at their lower ends (screw axes 32 and 32 ).

If the umbrella stand is not used and is to be stowed away, for example, the support arches 40 can be separated from the foot 12 after the screw connection has been loosened. Subsequently, the guide arches 30 can each be folded down into the base plane, namely by means of pivot bearings, not shown, such as hinges or joints, which pivot the guide arches 30 about guide element pivot axes 34 or 34 allow that run parallel to the pipe pivot plane 18 and the base plane. Alternatively, the two guide bends 30 can also be pivoted about a common guide element pivot axis running parallel to the pipe pivot plane 18 and to the base plane. This measure prevents the distance between the two guide arches 30 from varying with the pivoting thereof, and thus enables dimensioning such that the guide arches 30 always lie more or less closely on the receiving tube 14. For example, a pivot bearing 16 as shown in FIG. 4 can be used and the common guide element pivot axis run coaxially with the axle pin 20 '. This allows the orientation of the receiving tube 14 to be largely arbitrary if the support elements 40 are designed in such a way that they allow the guide bends 30 to be pivoted. Such support element constructions are described below in the context of exemplary embodiments.

It is clear that instead of the pivot bearing of the guide arches 30, a preferably detachable screw connection to the foot 12 can also be provided. Instead of the screwing of the support arches 40, a corresponding support element pivot bearing can also be provided for pivoting the support arch 40 about a support element pivot axis 42. In this case, in contrast to the example shown, it is advantageous if the guide element pivot axes 34, 34 on the one hand and the support element pivot axis 42 on the other hand run at different distances from the foot plane (see, for example, FIGS. 6 and 7) in such a way that these two components of the umbrella stand can be folded down into the area of the foot plane without interfering with one another in the folded state. For a further reduction in the space requirement of the umbrella stand not used, the parts of the foot 12 can also be connected to one another in a detachable or articulated manner, preferably in such a way that after folding, all the foot parts extend essentially in a common plane. By folding down the guide elements 30, the support elements 40 and the receiving tube 14 into the region of the base plane, it can even be achieved that after folding, all of the components of the umbrella stand essentially extend in a common plane. 5 can be designed, for example, as shown in FIGS. 3 or 4, the pivot bearing 16 being expediently attached to the foot 12 in the center of the foot plane.

6 and 7 show a further exemplary embodiment of an umbrella stand 10, which is similar to the example shown in FIG. 5. Again, two guide bends 30 running on both sides of the pipe pivot plane 18 are provided, which about guide element pivot axes 34, 34 are pivotally attached to the foot 12. These guide arches have circumferentially spaced and aligned pairs of holes 50. The holes 50 are arranged at regular intervals from one another over the pivot path 19 of the receiving tube 14 in such a way that the receiving tube 14 is held in one of several tube pivot positions by inserting retaining pins 52 can. Fig. 6 shows the receiving tube 14 in its extreme right-angled pivoting position, wherein it is held by the retaining pin inserted into the rightmost hole 50, which supports the receiving tube 14, which is loaded to the right due to gravity.

At the upper end of the receiving tube 14 there is also a screwed-on clamping sleeve 26 recognize that a standpipe 15 inserted into the receiving tube of a screen stuck.

If the receiving tube 14 is to be kept in a vertical orientation, then in the two central holes 50 then the upper end of the receiving tube 14 are immediately adjacent to insert a retaining pin 52. The retaining pins 52 are preferably provided with a handle at one end and against loosening secured, for example by a split pin or one at its other end screwed wing nut. A corresponding fit can also be provided, which prevents an inadvertent leakage of an inserted retaining pin 52.

In the umbrella stand 10 shown in FIGS. 6 and 7 is a detachable Spacer part 60 (preferably made of plastic) provided that the two Guide arches 30 are supported in the transverse direction against each other and thus to the stability of the contributed by the two guide arches 30 guide structure. The U-shaped Spacer part 60 can at various locations in the circumferential direction of the Guide sheet 30 are attached and is shown in Fig. 8 in more detail. It has two incisions 62 for receiving sections of the guide sheets 30. Die Flat sides of the guide arches 30 are radial and circumferential of the arches 30 distributed grooves 61 provided in the corresponding Projections of the spacer part 60 can engage in the area of the incisions 62. At the lower end of the spacer part 60 in FIG. 8 there are retaining lugs 64, which secure the spacer part 60 in the plugged-in state against loosening. When the spacer parts 60 are pulled off (upwards in FIG. 8), they become Retaining lugs 64 deformed elastically and thus allow the removal of the Spacer part 60.

The detachability of the spacer part 60 is advantageous both for disassembly or folding the umbrella stand as well as in the context of an embodiment variant, the two spacer parts 60 also have the function of holding the Take over the receiving tube 14 and the grooves 61 are arranged accordingly. The Holes 50 and the holding pins 52 are then unnecessary.

In the umbrella stand shown in FIGS. 6 and 7, the guide arches 30 can pivot about guide element axes 34, 34 be pivoted into the area of the foot level. Axes 34, 34 are arranged using bearing blocks 36 attached to the foot 12 at a distance from the foot plane, which also allows a support arch 40 to be folded down into the foot plane without spatial obstruction when the guide arches 30 are folded down. For this purpose, the corresponding support element pivot axis 42 is arranged directly on the base plane. The support arch 40 extends from a section of the foot 12 on one side of the pipe pivot plane 18 continuously to a section of the foot 12 on the opposite side of the pipe pivot plane 18 and is articulated to the foot 12 at both ends by a pivot bearing, but this is not shown pivot bearing have the common pivot axis 42. The support arch 40 runs underneath the guide arch 30 and is provided on its outer circumference with two transverse grooves, into which the lower sections of the guide arch 30 engage and are thus secured against tilting in the transverse direction. To use the umbrella stand 10, the pivoting position of the support arch 40 can be determined such that pivoting of the receiving tube 14 is not hindered.

An interesting variant of the umbrella stand shown in FIGS. 6 and 7 10 results when the pivotability of the support arch 40 for adjusting the Orientation of the receiving tube 14 along the tube pivot plane 18 is used, by the section of the support bend located in the region of the pipe pivot plane 18 40 is used to hold the receiving tube 14. In this case the holes are 50 and the holding pins 52 are unnecessary. It is only necessary to ensure that the support arch 40 can be determined in the desired pivot position. in the Crossing areas between the support arch and guide arch can also be used as a means of securing be provided (e.g. spacer parts as described above). Furthermore, it is possible, two support arches 40 arranged on both sides of the receiving tube 14 insert that follow the pivoting movement of the receiving tube. This gives the Umbrella stands have a special aesthetics due to the symmetry then present also simplifies holding the receiving tube in the vertical position. The coupling the or the support arches with the receiving tube also ensures that the Support is always given at the point where a transverse load may occur.

9 and 10 show a further embodiment of an umbrella stand 10, which differs from the example shown in FIGS. 6 and 7 essentially differs in that that on both sides of the pipe swivel plane 18 each about a swivel axis 42 pivotable support arch 40 is provided. The radially outer and radially inner Edges of the upper end portions of these support arches 40 are aligned with the radially inner ones and outer edges of the guide arches 30. The two support arches are in use 40 through an arcuate, passing under the guide arches 30 Connection part 44 connected to each other. For example, the connecting part 44 be detachably or pivotably pinned to the respective upper sections of the supporting arches 40, as indicated in Fig. 10 at 46. The connecting part 44 has at its upper Edge two grooves in which the guide arches engage from above. The function of this Umbrella stand corresponds to the function of that shown in FIGS. 6 and 7 Umbrella stand.

Fig. 11 shows a further embodiment of an umbrella stand 10, which differs from the example shown in FIGS. 6 and 7 essentially through the use one attached to the receiving tube 14 (e.g. welded on) and a total of 70 designated locking device differs. The locking device 70 has two Locking pins 72, which in the illustrated state are preloaded elastically into a pair of Recesses engage 50 and thereby the receiving tube 14 in its Hold the swivel position. The support arch 40 is pivotable with bearing blocks 36 connected to the foot 12. The pivoting takes place about a support element pivot axis 42, which is coaxial to the pivot axis (axle pin 20) of the receiving tube 14 runs. The support arch 40 is with the locking device 70 or the receiving tube 14 connected (not shown; e.g. screwed), so that the pivoting of the Receiving tube 14 is coupled to the pivoting of the support arch 40. Thereby the support arch 40 is mechanically advantageous always in a swivel position, which corresponds essentially to that of the receiving tube 14.

FIG. 13 shows the locking device, designated overall by 70, in more detail in one State in which it holds the receiving tube 14 locked in position. This Holding takes place, as can be seen from Fig. 13, by positive engagement of the Locking pins 72 in the recesses 50 on both sides of the locking device 70 arranged guide bends 30.

The pins 72 are each in the direction of an associated compression spring 74 Unlocking, i.e. preloaded inside. The compression springs are supported for this purpose 74 on the one hand on the inside of a housing 76 of the locking device 70 and on the other hand, from a spring support 78 connected to the spring. 13 is For the sake of clarity, the spring 74 together with the associated spring support 78 in right part of the figure omitted.

In the illustrated state, the pins 72 are disengaged from the recesses 50 prevented by respective stop of sperm socks connected to the pins 72 80 on a wedge carriage 82. In the example shown, this wedge carriage 82 has Stop area holding troughs 84.

In order to change the pivoting position of the receiving tube, the locking device 70 to unlock temporarily, i.e. pins 72 are disengaged from the recesses Bring 50. This is done as follows: The operator pulls you with one of Hand knob connected to the push rod 88 screwed into the wedge slide 82 at the top 86 up. As a result, the sperm socks 80 come out of the holding troughs 84 and each slide on one of two contact surfaces 90 of the wedge slide 82 to in a lower area of the wedge slide 82. Due to the shape of the contact surfaces 90 and the preload of the springs 74, the locking pins 72 get out of the Engagement with the recesses 50.

Now the operator can change the pivoting position of the receiving tube 14 in change the way you want and then release the knob 86, which together with the push rod 88 and the wedge slide 82 through a the push rod 88 surrounding compression spring 92 is biased in the direction of the locking position. The Design, in particular the shape of the contact surfaces and the spring force relationships are chosen such that a total preload in the direction of a lock is present. As a result, a further pivoting of the receiving tube 14 in the vicinity of a pair of recesses 50 that the wedge slide 82nd moves back into its locking position, the sperm socks 80 the Slide the contact surfaces 90 in the opposite direction and the locking pins 72 latching into engagement with others corresponding to the selected swivel position Recesses 50 come. So that the receiving tube 14 is finally in the desired new swivel position locked again.

With regard to the specific construction of the locking device, there are numerous Variants conceivable. Such a variant is illustrated in FIG. 14. This figure shows a modified detail from Fig. 11, with instead of the up to unlock pulling the hand knob of the previously described version for unlocking Lever 86 to be pivoted above is provided. It is also with this variant preferably, the locking pins 72 together with the handle (here: lever 86) preload elastic in the sense of a lock, so that a release of the corresponding handle finally forced to lock in the leads to the next possible swivel position. It should be noted that the locking in the Meaning of a continuous adjustability also by a frictional engagement of the Locking pins could be realized with at least one guide arch 30.

Fig. 15 shows schematically a detail of the umbrella stand shown in Figs. 9 and 10 in the folded state. It is clear from this that foot parts 12, 12 and 12 after collapsing extend substantially in a common plane E. In this state, the guide arches 30 and support arches 40 also extend essentially in the plane E. In this state, the umbrella stand can be stowed in a particularly space-saving manner.

FIG. 16 shows a variant of the possibility of an already explained with reference to FIG. 15 articulated connection of foot parts. Deviating from that shown in Fig. 15 Execution here are the two corresponding foot parts 12 'and 12' 'without a central one Foot part 12 directly connected to each other. This articulated connection can e.g. like that be formed that interdigitated end portions of the foot portions 12 'and 12 '' together from an axle bolt (orthogonal to the drawing plane of Fig. 16) be enforced.

The components of the umbrella stand that shape the external appearance (e.g. Foot parts, guide elements and support elements) should expediently consist of one and be made of the same material, for example from weatherproof wood or Plastic. Screw connections can then advantageously be used using countersunk Threaded bushings are executed. A version made of metal is also cheap which improves the stability of the umbrella stand due to the relatively large weight is. Finally, there is a varnishing or coating of umbrella stand components into consideration.

For the receiving tube 14 and the pivot bearing 16, the use of Metal (e.g. steel or aluminum), but plastic is also used for this can be made, especially if the remaining components are made of plastic are. It contributes to a particularly appealing appearance of the umbrella stand even if the umbrella stand has at least one plane of symmetry. Further is it is preferred if the contour of the umbrella stand as a whole is a shape cut ball, especially hemisphere (see e.g. Fig. 5), or a cut ball Owns ellipsoids.

Figures 17 to 22 illustrate further aspects of the invention that relate to the Realize and arrange a swivel bearing. For all described below Embodiments is the risk of the umbrella stand tipping over advantageously reduced.

Fig. 17 shows schematically from the side another embodiment of an umbrella stand 10, which differs from that shown in FIGS. 6 and 7 essentially thereby distinguishes that the pivot bearing 16 is arranged off-center on the foot 12. The Other design corresponds to the examples already explained above, with the For the sake of clarity, the support element 40 is omitted.

The pivot bearing 16 provided in the vicinity of the base plane can also be displaced be arranged, e.g. 18 (shift in the direction of the double arrow). A particularly simple pivoting process results when one Relocation of the pivot bearing forcibly swiveling the receiving tube leads. By means of a further pivot bearing 16 ', a receiving tube sleeve 14' be rotatably mounted approximately centrally over the foot, in which the receiving tube 14 at Pivoting slides. The sliding bearing of the lower swivel joint 16 can e.g. as can be seen in FIG. 21. However, design variants are also conceivable, which the expert can easily find.

Fig. 19 shows an umbrella stand, the base of which is essentially two V-shaped arranged foot parts 12 ', 12' 'is formed, which preferably as shown via a Hinge for collapsibility are interconnected. To build in Condition of stabilizing this V-shape are the ends of the foot parts 12 'remote from the hinge, 12 '' connected via a spacer. It is advantageous for safety against tipping over this version, the extensibility of foot parts laterally in the direction of Pipe swivel plane. For this purpose, foot sections can be inserted as a hollow profile with extendable extension parts (such as parts 12 '' 'and 12' '' 'in Fig. 19). To support a further swivel joint 16 'against the foot 12 are two support struts 30 'are provided, which together with the receiving tube 14 without additional Parts form a relatively stable tripod. The receiving tube sleeve is here as Clamping sleeve immovably attached to the receiving tube. If desired, at appropriate training of the clamping sleeve and the receiving tube at the same time Umbrella shaft can be clamped in the receiving tube. There is a recess in the Favorably receiving tube through which the clamping sleeve directly onto the umbrella shaft can act to clamp it. A pivoting takes place by relocating one the cross connecting rod connecting the two lower ends of the two support struts, the form-fitting in corresponding recesses of the foot parts 12 ', 12 '' engages and thus the locking of the receiving tube 14 in the desired position enables. These are spaced apart, here groove-shaped recesses form an adjustment grid which shows the adjustable inclination positions Are defined.

20 shows details of a modification in which the support struts 30 'do not or in one middle area of the same are interconnected. A pin-hole lock can also be used as shown.

Fig. 21 shows an umbrella stand in which the cross-connecting rod itself at the same time forms a foot part 12 '. Another goes from the middle of this foot part 12 ' Foot section 12 '', which has a locking / sliding bearing for lockable displacement of the pivot bearing 16. The lock can e.g. as shown by intervention a pin into one of a series of openings. The pin is in gear connection with a arranged in the region of the further pivot bearing 16 ' Locking handle. The pin is preferably elastic in its direction of engagement preloaded. Tensioning ropes 12 '' ', 12' '' 'ensure increased stability of the foot. Here it is advantageous to use a turnbuckle. Alternative to the tension ropes are also rigid hollow profiles conceivable. These could be advantageous extendable extension bars record (see Fig. 19).

Finally, the embodiment according to FIG. 22 has the peculiarity that the Support struts 30 'together with the cross connecting rod one over the foot parts 12', 12 '' protruding course, in the outer area of this course Floor supports are provided, which further increases the safety against tipping over. Here The support struts 30 'can be formed in one piece with the cross connecting rod. Alternatively, the struts can also be detachably connected to the cross connecting rod be (e.g. pluggable).
