Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 to German Patent Application No. 20 2024 000 467.8, filed Mar. 8, 2024, and to German Patent Application No. 10 2024 123 467.9, filed Aug. 16, 2024, the entire contents of these applications is herein expressly incorporated by reference.

BACKGROUND AND SUMMARY OF THE INVENTION

Exemplary embodiments of the invention relate to a standing board that has a wide range of positive effects on health and can be used for a variety of purposes.
Relevant state of the art is disclosed by US 2017/0361143 A1, WO 2018/192138 A1, US 2019/0154115 A1, US 2018/0353789 A1 and DE 94 06 778 U1.
Balance boards promote balance, strengthen various muscle groups and promote all the positive properties of standing, but usually have the following disadvantageous properties:

- a) a rigid standing surface:
- Due to a rigid standing surface (board) on which both feet are positioned, no independent movements of the feet are possible; and
- b) mounting of the standing surface:
- Usually such boards are mounted on a movable roller or even a ball. Thus, a high degree of concentration as well as a sense of balance is required, which makes these boards almost exclusively usable for sporting purposes.

In view of the above, exemplary embodiments of the present invention are directed to a standing board that can be used at any time without the user having to meet certain requirements.
The standing board has a frame with an aluminum extruded profile with a mounting groove at the bottom. The frame offers the option of arranging feet and/or other accessories in any position and any number using screw connecting elements that are guided by sliding on the extruded profile.
Suitable screw-type connecting elements can be, for example, sliding blocks with corresponding threaded holes. Corresponding sliding blocks are slidably guided in grooves of the extruded profile. However, the basic idea of this connection also suggests the well-known option of achieving a screw connection between the frame and the feet, comparable to the aforementioned sliding block screw connection, by mounting screw heads of feet within the said mounting groove.
In particular, the aforementioned screw connection fixes the position of a respective foot within the aforementioned mounting groove.
The extruded profile is in particular designed as a hollow chamber profile.
The frame can have an opening that can be closed by a closure element. The closure element can be designed in the manner of a sleeve or tube.
The opening to be closed by the closure element can have a circumference of about 20 mm.
In the context of the present invention, closed and/or compressed rubber cable rings can be threaded through the opening and connected to the mat by means of cable bolts. After the rubber cable rings have been installed, the opening can be closed with the said closure element.
Furthermore, according to the invention, the connection of the mat to the frame can be realized by means of cable bolts guided through loops attached to the mat, and these can be elastically connected to the frame on each side by at least one rubber cable ring.
As cable bolts, rod-shaped elements can be used that have a bearing surface for loops with two radially protruding projections arranged on the edge of the bearing surface. This serves to better position the cable bolts in relation to the rubber cable rings.
The rubber cable rings are preferably designed as loops, with a loop for encircling the frame profile and two interconnected cable ends. The loop shape defines a tapering area in which the cable bolts are arranged. This makes additional fixing of the cable bolts unnecessary, as their position is predefined by the tapering.
In a constructively advantageous way, exactly two rubber cable rings are always connected to exactly one cable bolt with exactly one loop of the mat.
The cable bolts can advantageously be arranged loosely, i.e., without additional fasteners or fabric closure, in the taper of the loop-shaped rubber cable rings. The hold and the position are provided by the pull of the loop towards the mat, which presses the cable bolt into the taper as a bearing seat.
The loops attached to the mat are preferably connected to the mat in a materially bonded manner, in particular glued and/or sewn to the mat.
To reduce weight, the feet can be designed as hollow profiles.
Preferably, there can be six feet.
In contrast to the balance board described at the beginning, the standing board according to the invention does not have a rigid standing surface, but a mat held in a rubber-elastic manner by means of cable rings. The mat is held by several cable bolts, which are each wrapped around by two cable rings at each end and which are wrapped around in the middle by a loop attached to the mat.
Due to a preferred application at the workplace, the mat of the standing board and/or the frame of the standing board can be oval.
Apart from the opening, which is groove-shaped, the rest of the frame of the extruded profile is one-piece and designed as a circumferential oval shape.
Moreover, the mounting groove is formed around the entire length of the extruded profile, i.e., also around the slit-shaped opening.
A corresponding standing board with a frame and a mat attached to it can also have a frame component and/or a profile in another variant according to the invention. According to the invention, this frame component and/or profile is fixed to the remaining frames by means of a connecting element. The connecting element has a receiving sleeve for inserting the ends of one or more frame profile elements, in particular extruded profiles. The receiving sleeve also has a receiving opening for inserting the frame component and/or the profile, and the receiving sleeve has a clamping piece that is arranged in a movable manner in the receiving sleeve, so that the frame component and/or the profile can be fixed in the receiving sleeve by the clamping piece in a clamping manner.
The connecting element enables a stable connection of elements that project from the frame contour bordering the mat, without there being a significant reduction in the stability of the frame contour.
It is advantageous if the receiving sleeve has a fixing means for fixing the linear movement between the receiving sleeve and one or more frame profiles of the frame.
The movement of the clamping piece can be advantageously triggered by an actuating element in an uncomplicated manner, wherein the actuating element is designed as a lever, a handle, a handwheel and/or a tool engagement.
A threaded rod can be provided between the respective actuating element and the clamping piece, so that the threaded rod and the clamping piece can be supported on a thread arranged in the receiving sleeve.
For a defined transmission of clamping forces, it is advantageous if the clamping piece is guided linearly movable in the receiving sleeve.
It is also advantageous if the receiving sleeve has two opposing receiving openings for receiving the frame component and/or the profile. This allows the insertion depth and the circumference of the double-sided projection of the frame component and/or the profile to be adjusted.
Finally, the clamping piece can have one or more guide segments, which is or are matched to the width of a hollow chamber of the extruded profile designed as a hollow chamber profile, so that simple guidance is possible without additional guide means.

BRIEF DESCRIPTION OF THE DRAWING FIGURES

In the following, the invention will be explained in more detail by means of an exemplary embodiment with the help of the accompanying figures. The figures show as follows:

FIG. 1 shows an isometric view from above;

FIG. 2 shows an isometric view from below;

FIG. 3 shows isometric details;

FIGS. 4 a-c show various views of a connecting element as part of the standing board according to the invention.

DETAILED DESCRIPTION

FIG. 1 shows a standing board according to the invention, having a frame 1 and a mat 4, which is attached to the frame by cable rings 3. The mat 4 is designed to be movable. The mat 4 can be made, for example, from a sewable plastic mat. The seam to a rear loop, not shown in FIG. 1 , can be made as a thread seam, adhesive seam or welded seam. Accordingly, the material of the plastic mat can be made to be sewable, bondable, and/or weldable.
The frame 1 has an extruded aluminum profile 8. The extruded profile is designed as a hollow chamber profile, as can be seen from FIG. 3 , among other things. The view of FIG. 1 shows the top side of the standing board with the visible side of the mat 4.
FIG. 2 shows the standing board from its underside. The aforementioned loops 4.1 are visible from this side. They are attached to mat 4 by a seam. A loop 4.1 wraps around the bearing surface 5.1 of a cable bolt 5. The bearing surface 5.1 is arranged between two radially protruding projections 5.2. Axially spaced from each of these projections 5.2, the cable bolt 5 has a further projection 5.3. Between the projections 5.2 and 5.3 is a groove for receiving and supporting the cable strands of a cable ring 3 before their connection 5.4. The connection 5.4 of the cable strands, providing the loop-shaped cable ring 5, can be achieved by means of a materially bonded connection or by means of a mechanical connection, e.g., a clamping connection, preferably by means of a ring clamp, in particular by means of a metal sleeve or by means of a winding.
As can be seen in FIGS. 2 to 4 , the respective cable rings 5 are not round, but are designed in a loop-shaped manner. Due to the tapering 5.5 of the cable ring before the connection 5.4 of the two cable strands of the loop-shaped cable ring 3, both cable strands can be placed in the groove between the projections 5.2 and 5.3, thus axially positioning the cable ring on the cable bolt. The projections 5.2 are not absolutely necessary, as the position of the cable rings 5 is also made possible by the loop 4. However, the spacing between the cable ring 3 and the loop 4 is advantageous due to the projection 5.2 in order to avoid load-related friction between the cable ring 3 and the loop 4.
Advantageously, exactly two cable rings 3 each wrap around a single cable bolt 5 to connect to the frame 1, which in turn is wrapped around by a single loop 4.1 and is thus connected to the mat 4.
As viewed from below, the frame 1 of the standing board has a mounting groove 1.1. As can be seen in FIG. 3 in particular, the mounting groove 1.1 has an opening slot 6 and a receiving space 7 arranged in the extruded profile. As can be seen in the sectional view of FIG. 3 , the receiving space 7 is wider than the opening slot 6. This makes it possible to hold a screw connecting element, e.g., a sliding block with a screw thread channel or the screw head of a bolt. Without a clamping connection with a corresponding screw connecting element, the screw connecting element mounted in the mounting groove 1.1 is arranged so that it can be displaced along the longitudinal extension of the mounting groove of the strand profile.
The screw connecting element mounted in this way is connected to feet 2 in FIGS. 1 to 4 . The feet 2 are designed as hollow tubes and have a screw connecting element corresponding to the screw connecting element mounted in the mounting groove. This can be a plug mounted in the hollow tube with a threaded rod extension, which can enter into a screwed connection with a sliding block. Alternatively, a screw connection can also be made by a mechanical reversal, so that the sliding block has the threaded rod extension and the plug in the base has a corresponding threaded hole. The sliding block is only one variant of the fixing. Comparable possibilities of fixing can be achieved, for example, by screws with screw heads or the like.
The mounting groove 1.1 enables many possibilities for fixing elements to the standing board. These can be, for example, feet and, alternatively, other accessories such as holding hooks, retaining rods, adapters, spacers for the cable rings and/or other components. The possibilities are many and can be combined with each other.
For the purpose of threading the screw connecting elements into the receiving space 7 of the extruded profile of the frame 1 and, optionally, also for the purpose of threading the loop-shaped cable rings 3, the extruded profile has a groove-shaped opening. The groove-shaped opening 1.2 can have an opening width of approximately 20 mm. However, the range of fluctuation of this can be up to several centimeters, e.g. up to 5 cm.
Closed and/or compressed rubber cable rings 3 can be threaded through this opening 1.2 onto the frame and connected to the mat 4 by means of cable bolts 5. After installation, the opening 1.2 is closed with a closure element 1.3. As can be clearly seen in FIG. 2 , the closure element can be sleeve-shaped. For example, it is possible and preferred if the closure element is designed to be linearly displaceable along the strand profile so that it covers the opening in a first position and releases the opening in a second position.
The connection of the mat to the frame is elastic due to the rubber cable loops. Various elastomer variants are possible as the rubber used. The cable strands of the rubber cable rings are advantageously designed as round strands, which are particularly resistant.
The standing board has an oval contour when viewed from above. This means that it requires little space.
The standing board 1 can be used at the workplace, for medical/physiotherapeutic purposes as well as for training purposes in the sports area.
The standing board has a frame with feet to ensure a certain ground clearance. Furthermore, the standing board has a mat attached to the frame by elastic rubber cable rings, which serves as a standing surface.
This design has the following properties, which are particularly effective when working in a standing position compared to sitting:

- Stable standing on a movable mat
- Both feet can be moved almost independently of each other
- Constant adjustment of balance promotes sense of balance/sensorimotor skills/coordination of movement
- Strengthening of the micro-musculature
- Promoting concentration
- Prevents tension
- Prevents back problems
- Prevents intervertebral disc problems
- Prevents rapid fatigue
- Compensates for lack of exercise

The standing board has the dimensions of approx. 1000×600×130 mm (L×W×H) and can be conveniently transported in a specially designed carrying bag.
FIGS. 1 to 3 show a one-piece extruded profile. However, it is possible that the frame is composed in an analogous form from several extruded profiles with multiple connecting elements.
FIGS. 4 a to 4 c show a further inventively developed variant of the closure element 1.3 as a connecting element 11 for connecting the ends of one or more extruded profiles to form a corresponding frame of a standing board.
The connecting element 11 has a receiving sleeve 12 into which the ends of the extruded profile can be inserted. The receiving sleeve 11 can have a fixing means 19 for fixing the linear movement between the receiving sleeve and the extruded profile 8 of the frame 1. The fixing can be carried out in an overlapping area where the connecting element 11 overlaps the extruded profile. A screw, for example, can be used as a fixing means 19, which is screwed against the surface of the respective extruded profile, so that a fixing is achieved. There are also other possibilities for a fixing means, for example a screw connection by means of a sliding block which is arranged in the mounting groove.
The connecting element 11 also has a clamping piece 13 which is connected to an actuating element 14. The actuating element 14 is designed as a lever in FIG. 4 , but it can also be a handle, a handwheel or a tool engagement, such as a screw head or a hexagonal receiver. Other actuating elements may also be provided. A threaded rod can be provided between the respective actuating element and the clamping piece 13.
When the threaded rod is rotated by the actuating element 14, the clamping piece 13 moves forward in a linear direction until it reaches a stop.
The receiving sleeve 12 has at least one receiving opening 15, preferably two receiving openings located opposite each other. The receiving opening 15 allows access to the opening 1.2 between the ends of one or more extruded profiles 8. The clamping piece 13 is arranged so that it can move linearly in the opening 1.2.
The insertion direction 16 for the frame component or the profile is perpendicular to the insertion direction for the ends of the extruded profile 8 or extruded profiles.
The frame 1 can be fixed to a further frame component and/or a further profile by the connecting element 11, by inserting the frame component and/or the profile through the receiving opening 15 into the area of the opening 1.2, so that at least one area of the frame component and/or the profile is arranged between the ends of the extruded component and/or the extruded components.
In the inserted state, the clamping piece 13 is moved by actuating the actuating element 14 up to the stop against the frame component and/or the profile and is then tightened, so that a clamping fixing in the inserted state on the rest of the frame 1 is achieved.
In the variant shown in FIGS. 4 a-4 c , the clamping piece 13 has a stamping surface 17, analogous to a stamping brake. At the edge of this stamping surface, the clamping piece 13 has one or more guide segments 18, which is matched to the width of a hollow chamber 9 of the extruded profile 8 designed as a hollow chamber profile.
Consequently, the guide segment 18 is inserted into the hollow chamber 9 and is guided in its linear movement in the hollow chamber. This advantageously prevents the clamping piece 13 from turning when the actuating element 14 is operated.
A corresponding guide element 18 can be provided on one side of the clamping piece 13 or on both sides, as shown in FIGS. 4 a-4 c , on both sides of the clamping piece 13, whereby a more linear movement of the clamping piece is achieved.
The frame component or the profile can, for example, be a bar for a railing, e.g. for use in gymnastics for senior citizens, or a bar, e.g., an angle bar for fixing the standing board to a wall. It is also conceivable that there could be a bearing sleeve that allows the feet to be inserted so that several standing boards can be stored on top of each other. There are a multitude of other possible applications.
