MAST BASE ANCHORAGE

Description

[0001] The invention relates to a mast base anchor, in particular for masts such as parasols, standing umbrellas, sports masts, flagpoles, rotary clotheslines, etc.

[0002] Anchoring systems for mast bases are known, for example, for standing umbrellas such as parasols. These systems comprise a shaft into which the mast base is inserted and then screwed tight. The height of the shaft depends on the load the anchorage will be subjected to, i.e., the height of the mast and the weight of the umbrella canopy, for example. Reference is also made to the solutions according to US 5 280 871 A and US 2019 / 368218 A1.

[0003] A particular disadvantage of the conventional mast base anchors is that the mast, which is usually very heavy - e.g. because a cantilevered umbrella canopy is attached to its upper end - must be raised to a height above the upper end of the shaft so that the mast base can be inserted into the shaft. This requires considerable effort from the user. This can also result in scratches, etc., which represent damage and are, above all, visually unsightly. Furthermore, with larger masts, screwing is necessary to fix the mast base to the shaft, which is also cumbersome and poses a further risk of damage to the mast.

[0004] Furthermore, as long as it does not hold a mast base, the shaft is open and can fill with water and debris when it rains, corrode or suffer other damage.

[0005] Therefore, it is an object of the present invention to provide a mast base anchorage that overcomes the disadvantages of the prior art.

[0006] This object is achieved by the subject matter of the present invention as disclosed in the description, the figures and the claims.

[0007] Accordingly, the subject of the present invention is a mast base anchorage comprising a mast base, a holder and a lever, wherein at least one receiving device with at least one element is provided in the holder, into which at least one complementary element on the mast base engages according to the key-lock principle when forming the mast base anchorage and can be releasably fixed by the lever.

[0008] In this case, the term "mast base anchorage" refers to a fixed combination of a "mast base", as the insertable part of the mast base anchorage, and a "bracket" as the ground-side part of the mast base anchorage.

[0009] According to the invention, both parts are specially designed to fit together. The lower part of the mast is referred to as the "mast base."

[0010] The "mount," on the other hand, is constructed from multiple parts. The term "mount" includes, for example, a base plate, screws, concrete, or other means for securing the mount. The mount includes, as an essential component, the "receiving device" into which the mast base is inserted. Furthermore, the mount includes at least one "element" in the receiving device into which the complementary element at the mast base is inserted.

[0011] Optionally and advantageously, a recess is provided in the receiving device in which the element for inserting the complementary element is located.

[0012] The "locking" of the mast base occurs, for example, when elements of the receiving device are "opened" by actuating the lever and, when the mast base is inserted, form an anchorage through the elements on the mast base, in particular in a form-fitting manner, or when a mast with a mast base having corresponding elements locks into correspondingly designed elements of a receiving device that is part of the bracket due to the weight of the mast.

[0013] A "lever" within the meaning of the present invention can be a hand or foot lever, for example, a pedal, a folding lever, and / or a plug-in lever. For example, the lever is connected to a spring or a spring system. Pressing the lever tensions the spring, causing the respective complementary elements to engage each other according to the key-lock principle when the mast is inserted. When the lever is released, the spring springs back, thereby securing the mast base anchorage formed according to the key-lock principle.

[0014] According to an advantageous embodiment, a locking system is further provided to fix, lock, or secure the position of the lever. This can be a mechanical lock that prevents the lever from being actuated and thus prevents the mast base anchor from being released. This can be used, for example, as a safety feature for securely fixing the mast base in the bracket.

[0015] The locking system can be a plug-in or hook closure, with or without a spring, a locking spring lock, a drop bolt or similar, with or without a locking device.

[0016] A "mast base" is the lower end of the mast of a standing umbrella, flagpole, etc., which is anchored to the ground and / or a base, i.e., fixed before the mast is free-standing and subjected to load, such as when the umbrella is unfolded. The upper end of the mast may be used to support an umbrella canopy, a flag, a baseball hoop, a rotary clothesline, or similar items, or even a maypole.

[0017] A "mount" in the present sense is the ground-side part of the mast base anchorage, which, for example, is at least part of a base and / or a base plate. For example, according to one embodiment of the present invention, the mount is integrated and / or embedded into a base on which a mast is to be erected. The mount can be part of a base plate embedded in the ground, but can also be part of a base—for example, weighted down with concrete and / or granite—possibly even movable on wheels.

[0018] The bracket is designed to hold a mast at the base of the mast. The bracket includes a recess into which the mast is inserted, as well as at least one receiving device with elements that stabilize the mast with the complementary elements, and a lever that can be used to secure the mast stabilized in the bracket to form the mast base anchor.

[0019] The recess can be relatively shallow, for example, the depth of a groove, or it can be a recessed sleeve—e.g., recessed into the ground or base—or a negative form of the mast base or the lower part of the mast base. In any case, the recess, within the meaning of the invention, is adapted to a mast base in such a way that the latter can be inserted into the recess.

[0020] The receiving device in the holder, which is open at the top, is preferably also shaped to accommodate the mast base. The recess has, for example, side walls and a base, thus forming a sleeve for the mast base. According to a preferred embodiment, the receiving device comprises a recess that represents a negative form of the mast base, for example, a conically tapered mast base. This allows for the formation of the preferred form-fitting mast base anchorage.

[0021] The bracket further comprises at least one receiving device with at least one element that serves, according to the key-lock principle, to receive at least one complementary element provided at the mast base. These complementary elements at the mast base and / or in the bracket are operated, for example, by the lever, in particular by being brought into a receiving "open" position so that the complementary element(s) of the other part can engage when the mast is inserted.

[0022] For example, the lever can also be integrated into the base plate or the base. The lever usually also has a counteracting element, such as a spring structure, and / or a surface loaded with the weight of the mast at the foot pedal. Either the lever and counteracting element are both integrated into the base and / or the base plate, or the lever and counteracting element are distributed between the mast base on the one hand and the base plate / base on the other.

[0023] Preferably, a foot pedal is provided by which the lever can be operated, so that the lever is arranged on the bottom side in the receiving device for forming the mast base anchorage.

[0024] According to the invention, the base-side support comprises at least one receiving device with at least one element which, according to the key-lock principle, serves to receive at least one complementary element provided on the mast base.

[0025] For example, by pressing the foot pedal, the element(s) of the receiving device is / are opened and the mast base can be inserted into the receiving device.

[0026] The locking system incorporates an additional safety device to ensure that the lever used to release the mast base from the mast base anchorage cannot be operated without intentionally opening it and / or without the locking system key.

[0027] Operating the lever first opens the mast base anchor and the mast base anchor is then released so that the mast base can be removed from the anchor.

[0028] The lever can, for example, be designed in such a way that it releases the mast base from the receiving device and simultaneously lifts it, so that, for example, by operating the foot pedal, the opening of the locked anchorage is reached and at the same time the mast base is lifted so that it can be easily removed from the recess in the holder.

[0029] For example, one or more hooks can be provided in the receiving device for engaging the mast base, which is provided with corresponding complementary elements, and which has a surface at its lower end such that by operating the lever, the hook(s) of the receiving device are pushed out of the complementary elements of the mast base and at the same time the mast base is lifted from below - see Figures 3 and 4 in addition.

[0030] There are a number of examples of at least one receiving device in the holder, each designed according to the key-lock principle in connection with the elements on the mast base, in which the mast base easily engages with one or more complementary elements in the receiving device of the socket created for this purpose and is then fixed there - for example by closing a lever.

[0031] In the simplest case, the mast base has one or two recesses, holes and / or eyelets and the receiving device has a corresponding number of movable hooks, latches and plug-in elements that can be folded in and out, whereby the mast base is inserted into the holder, engages with the elements of the receiving device and is fixed.

[0032] According to another embodiment, the mast base has a groove or a thickening, e.g. in the form of a clamping ring, which finds a corresponding complementary element in the receiving device, such as a bead or nose, a projection, groove, one or more hooks and / or clamping rings for locking the mast base.

[0033] According to an advantageous embodiment, for example, the receiving device has an element such as a clamping ring into which the mast base is inserted, comprising a correspondingly complementary groove. It is particularly advantageous if the clamping ring comprises an insertion bevel with corresponding lugs forming a barb, so that the mast base is clipped in with its complementary groove and, like a barb, can only be released again after mechanically widening the insertion bevel using a correspondingly designed lever.

[0034] Figure 1shows the simplest embodiment of the receiving device for the socket 2 and the complementary elements—here, clamping ring 3—at the mast base 1, according to the key-lock principle. As soon as the mast base 1 is inserted, a complementary element in the form of a groove 4, i.e., a groove 4 shaped like the clamping ring 3, is provided in the holder 2 as a receiving device at the point, viewed vertically, where the mast base 1 has a clamping ring 3.

[0035] The representation according to Figure 1shows a design in which the mast base 1 is virtually clipped into the holder because the insertion bevel 5 opens at the lugs 5 of the insertion bevel 5 when inserted, but is widened by a lever (not shown) for the removal of the mast base 1. When inserted, the circumference of the mast base is therefore the lever that opens the insertion bevel 5 and thus enables the mast base to click into place in the holder or its receiving device 2. For example, it is provided that there is a movable plate, a post, stamp or similar on the base of the receiving device, on which the mast base stands in the mast base anchorage and which is also connected to the lever. When the lever is operated, the plate together with the mast base on it is lifted by the lever force so that it can be easily lifted out of the receiving device of the holder.

[0036] The receiving device can also consist of one or more hooks which hook into corresponding recesses on the mast base when the mast base is inserted and thus hold it in position.

[0037] This is shown in the Figure 2 shown. Figure 2again shows a mast base 1 with a groove 6. The mast base 1 is inserted into the recess 7 of the bracket for anchoring. By actuating a lever (not shown) and when inserting - see arrow 8 - the mast base 1 into the recess 7, one or more hooks 10 - for example attached to a spring 9 - which protrude / protrude into the recess 7 in an untensioned state, are bent outwards until they spring back at the point of the groove 6 in the mast base 1 when the lever is released and the spring 9 is tensioned and hook / hooks into the groove 6 of the mast base 1. When released, the spring is tensioned again by the lever and the hooks 10 fold back, the mast base can then be easily removed again.

[0038] It is advantageously provided that a movable pin or a movable plate (not shown) is located at the bottom of the recess 7, which is also connected to the lever and by means of which the mast base is lifted via the lever force when the lever is actuated, so that it can be easily lifted out of the receiving device of the holder.

[0039] In an advantageous embodiment of this variant - see Figures 3 and 4 - a surface 14 is provided on the hook 10 at the other end 14, which does not engage in the groove 6, whereby when the lever is actuated, the hooks bend back and at the same time the surface 14, which is conveniently located under the mast base 1 in contact with the surface 26, lifts it so that it is levered upwards and can be easily removed from the recess - see Figures 3 and 4 .

[0040] The embodiment in which hooks or other means for locking the mast base are moved by one or more springs when plugged in, i.e. for example, are folded sideways from their position under tension of the spring(s), is particularly suitable for operation by means of a foot lever, because when locking in the weight of the mast base 1 moves the hooks 10 through the spring 9 and when releasing or disengaging the weight for moving the hooks 10 is moved by a lever in the form of a foot pedal (in Figure 2 not shown) can be generated.

[0041] An exemplary embodiment of the invention, in which the lever is designed as a foot pedal, is shown in Figures 3 and 4 shown.

[0042] This shows Figure 3a perspective view from above, so that the foot pedal 13 can be seen, but also piece by piece and separated by hatching, a part of the bifunctional hook 10 with lifting surface 14 for the mast base 1, there complementary contact surface 26.

[0043] Shown in Figure 3 a mast base 1, which in the variant of the invention shown is tapered and square at the lower end of a round mast 11. The mast 11 itself is independently round or square, which here in Figure 3 The mast 11 shown is round. The mast base 1 has a complementary element in the form of a recess, opening, and / or hole 12 for forming the mast base anchorage with the base plate 2, into which the element 25 of the hook 10 of the receiving device of the base plate 2 can engage.

[0044] The base plate 2 has supports 23 with which it is fixed to a base surface (not shown).

[0045] To form the mast base anchorage, the mast 11 is inserted in the lowering direction 8 over the mast base 1 into the recess 7 of the receiving device so that its weight rests on the surface 14 of the hook 10.

[0046] By actuating the foot pedal 13, the surface 14 of the hook 10 comes towards the mast base 1 on its surface 26 and at the same time the element 25 is pulled out of the sleeve 24 of the recess 7, into which it projects when the foot lever is in the normal position, as shown.

[0047] To form the mast base anchorage by locking the mast base, the foot pedal 13 is pressed, pulling the element 25 of the hook 10 out of the sleeve 24 so that the mast base 1 can be inserted into the sleeve 24. As soon as the mast base 1 is inserted into the sleeve 24, the foot pedal 13 is released, and the spring (not shown) on the spring suspension 27 presses the element, here, for example, the latch 25, into the complementary opening 12 provided for it on the mast base 1, so that the latch 25 locks into the opening 12 according to the key-lock principle.

[0048] The recess 7 is adapted to the mast base 1 with the sleeve 24 in that it is also conically shaped and thus realizes the advantageous variant of the present invention with the positive connection between the mast base 1 and the recess 7.

[0049] Figure 4shows the same embodiment, but a view from below of the underside of the base plate 2. Visible are the supports 23 of the base plate 2 and the hook 10, which has the element 25 for hooking into the opening 12 at the mast base, but also has the support surface 14 at its other end and is connected to the foot pedal 13. When the mast is anchored (not shown), the mast base 1 rests with its underside 26 on the surface 14 of the hook 10.

[0050] The hook 10 with the element 25 is designed in such a way that it engages with the complementary element of the mast base 1, here the opening 12, to form the mast base anchorage when the foot pedal 13 is in the rest position. Via a spring (not shown), which keeps the hook 10 tensioned via a spring suspension 27, the hook 10 forms the core of the mast base anchorage via the element 25 with the opening 12 of the mast base 1 according to the Figures 3 and 4 shown exemplary embodiment of the present invention.

[0051] When releasing the mast base anchorage, the foot pedal 13 is pressed, thereby opening the element 25, which here can be designed as a simple latch, the holder and at the same time the foot pedal 13 lifts the mast base 1 via the surface 14 connected to it, so that it can be easily removed from the recess 7.

[0052] The mast base can be round, oval, rounded, or square, regardless of the shape of the mast above. It has been found that a square mast base is easier to hold in position, especially against twisting within a sleeve.

[0053] The invention shows for the first time a technology in which a mast is erected via elements of its mast base and complementary elements of a holder on the ground or in the base and not via a complex lifting into a shaft of a base / base plate, but is simply inserted into a recess in a way that protects the material, where it engages in a holder of the mast base anchorage according to the key-lock principle and can be fixed and / or released again by a lever, wherein the construction is advantageously designed in such a way that the mast base is lifted by the leverage effect when the mast base anchorage is released.
