Rollable stand for holding umbrellas and similar objects with lowerable base elements

Abstract

Rolling stand for holding umbrellas and similar items, with rollers for mobility and with several floor elements characterized by that the floor elements are movable between a raised position to create a mobile state and a lowered position to create a stationary state.

Description

Technical field

[0001] The invention relates to a mobile stand for holding umbrellas and similar rod-shaped objects, in particular an umbrella stand, with wheels for mobility, in particular swivel casters, and with base elements for switching between a mobile and a stationary state. State of the art

[0002] Common mobile stands often feature casters with locking brakes or casters that can be moved up and down between a mobile and a stationary position. In these designs, the casters perform both the mobile and stationary functions. This can lead to design limitations, increased complexity, or reduced stability, especially in the case of heavy or tall stands. Object of the invention

[0003] The object of the invention is to provide a stand device which • can be operated either in a mobile state or in a stationary state, • is easily movable when in a mobile state and • can be switched between a driving state and a stationary state without lifting or tilting, solely by means of an operating element, which can be operated, for example, with the foot. Solution to the task

[0004] The problem is solved by a mobile standing device with wheels, in particular swivel casters, and with several base elements that can be moved between a lowered position and a raised position by means of an actuating element.

[0005] When the base elements are raised, the stand is mobile and can be moved via its casters. When the base elements are lowered, the stand is stationary, with the base elements resting on the ground and preventing movement.

[0006] The switch between the mobile state and the stationary state is made by means of an actuating element, preferably by foot operation.

[0007] The standing function operates independently of whether the casters are locked or blocked. Advantageous design

[0008] In an advantageous embodiment, the floor elements are designed as elastic feet, in particular as rubber feet. It is expedient to provide at least three, preferably four, floor elements.

[0009] It is particularly advantageous if the floor elements are evenly distributed under the base plate, resulting in an even load distribution and increased stability against tipping.

[0010] The actuating element can be designed as a foot lever, via which the floor elements are moved together between the raised and lowered positions.

[0011] For large or particularly wind-prone umbrellas, additional weights, especially concrete or cement blocks, can be placed under the base plate to further increase stability.

[0012] In a further embodiment, all the casters could be designed as swivel casters, pivotable around a vertical axis, to enable particularly easy maneuvering of the stand.

[0013] Alternatively, the stand can have two casters positioned side by side, with a predetermined direction of travel and fixed casters. This ensures a straight and controlled movement of the stand, especially with large or heavy umbrellas.

[0014] An embodiment of the invention is described in the Fig. Numbers 1 to 4 are shown.

[0015] Fig. Figure 1 shows the stand (1) in a perspective top view. This view shows the base plate (2) and a mounting element (6) for holding an umbrella pole. The casters (3) and the base elements (4) are provided by design but are not visible in the illustrated view.

[0016] Fig. Figure 2 shows the stand (1) in a sectional view AA with the base elements (4) lowered in the stationary position. A mechanism is arranged under the base plate (2) which allows the base elements (4) to move between a raised position and a lowered position.

[0017] The mechanism comprises a scissor mechanism (7) which is operatively connected to the floor elements (4). By means of a scissor-like movement of the scissor mechanism (7), the floor elements (4) are moved from the raised position to the lowered position.

[0018] The mechanism is actuated by the actuating element (5), which acts on the scissor mechanism (7) via a flat rod (8). Actuating the actuating element (5) moves the flat rod (8), thereby pushing the scissor mechanism (7) apart and lowering the floor elements (4).

[0019] A spring (9) is provided to reset the mechanism, returning the scissor mechanism (7) to its initial position when the actuating element (5) is released. This moves the base elements (4) back into the raised position, so that the stand (1) is in a mobile state.

[0020] The in Fig. Figure 2 of the mechanism shown is schematic and serves to illustrate the operating principle. The specific design of the scissor mechanism (7), the flat bar (8) and the spring (9) can vary without departing from the basic concept of the invention.

[0021] Fig. Figure 3 shows the stand (1) in sectional view BB with the floor elements (4) raised in the mobile state. In this state, the floor elements (4) are positioned relative to the position shown in Figure 3. Fig. 2. The device is raised in the state shown and out of contact with the ground, so that the stand (1) is freely movable over the rollers (3).

[0022] The scissor mechanism (7) located under the base plate (2) is in a resetted starting position. The flat bar (8) is correspondingly relieved of tension, and the spring (9) holds the scissor mechanism (7) in this starting position.

[0023] By resetting the scissor mechanism (7), the base elements (4) are moved into the raised position, thereby changing the stand (1) from the stationary state to the mobile state. The changeover occurs without blocking or locking the casters (3).

[0024] The in Fig. The embodiment shown in Figure 3 is schematic and serves to illustrate the state of the stand device in mobile operation.

[0025] Fig. Figure 4 schematically shows a sectional view AA of the stand device (1) with a sectional representation of the mechanism for switching between the stationary state according to Fig. 2 and the drivable condition according to Fig. 3.

[0026] A scissor mechanism (7) is arranged under the base plate (2) and is operatively connected to the floor elements (4). The scissor mechanism (7) is coupled to the actuating element (5) via a flat rod (8).

[0027] When the actuating element (5) is activated, the flat rod (8) is moved, which pushes the scissor mechanism (7) apart. This scissor-like movement moves the base elements (4) towards the ground and into the lowered position, thus bringing the stand (1) into the stationary state.

[0028] A spring (9) is provided to reset the mechanism, returning the scissor mechanism (7) to its initial position when the actuating element (5) is released. This moves the base elements (4) back into the raised position, allowing the stand (1) to be moved on the rollers (3).

[0029] The in Fig.Figure 4 of the mechanism shown is schematic and serves to illustrate the operating principle. The specific design of the scissor mechanism (7), the flat bar (8), and the spring (9) can vary without departing from the basic concept of the invention. Application example of the invention

[0030] The stand is particularly suitable as an umbrella stand for outdoor and indoor use, as well as in the entrance areas of residential and commercial buildings, in restaurants, or in public facilities. Furthermore, the invention can also be used for other elongated or tall objects placed on the ground where both easy maneuverability and increased stability are required, for example, signs, clotheslines, Christmas tree stands, cameras, construction site lights, or streetlights. It can also be used for other tall or stability-critical objects where a combination of easy maneuverability and high stability is necessary.
