Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt-prevention type floor fitness apparatus having a variable step height according to the general concept of claim 1 and a floor fitness apparatus having an extension stand surface.

[0002]

BACKGROUND OF THE INVENTION Floor fitness equipment comprising a footboard and an associated lower structural member which can be used to change the step height or also the inclination of the floor fitness equipment is becoming increasingly popular.

There are various types of training that can utilize this floor fitness apparatus. It can, on the other hand, be used as a bench that can sit or lie without the lower structural member, or it can also be raised with the lower structural member on both sides. But the fantasy of this sports educator or also private user is limited in terms of operational safety.

[0004] Especially when the device is used without supervision, tilting safety is compromised when lower structural members are placed on one side of this floor fitness device, for example to adjust the tilt, which is a serious accident. It may reach.

From the German utility model G 9108940, a floor fitness device with a variable step height is known, in which relative safety is achieved by the use of an arcuately cut bearing surface. However, the construction of such a floor fitness device, i.e. the tread and the lower structural member, requires an improvement in holding capacity when a large number of lower structural members are used. That is, by using the two lower members, the side wall of the tread has already been placed on the lower structural member,
Moreover, it was found that the arcuate bearing surfaces do not formally connect.

However, very precisely during ski land training, ie when a relatively large tilt is to be adjusted, the holding safety is lost.

By the way, according to the present invention, it has been recognized that the relationship between the arcuate bearing surface of the tread and the arcuate supporting surface of the lower structural member is important for enhancing the holding safety. In particular, the end of the arcuate notched bearing surface of the tread requires a shape that is adjusted according to the lower structural member used, so that the following side wall does not rest against undesired tilting. Another safety aspect is axial safety to prevent the lower structural member from slipping laterally with respect to the tread.

Also known is a floor fitness device having a variable tread height, which comprises a vertically elongated box-shaped upper member, a tread plate, and a number of smaller lower structural members. This building style assembly principle allows different heights and slopes to be obtained for practical use. However, some lower structural member is required to obtain a constant total height. If such a device can in principle be constructed so that it is also not tiltable by the support of the form connections between the assembly members, the tilting safety according to the technical rules of the stack principle is gradually reduced. Furthermore, in joint training, if there are a lot of lower structural members around, it may be a hindrance, and it may cause a stir.

This known fitness device is provided with a fixing member for hanging the expander band on the lower outer edge, which is not directly visible but can be seen only by tilting the head.

[0010]

SUMMARY OF THE INVENTION The object of the present invention is to determine the characteristics of connection by shape connection and physical training.
Anti-tilt floor fitness device that ensures that the arcuate bearing surfaces of the tread and the lower structural member overlap due to the shape connection even when the tilt of the floor fitness device is greatly adjusted by the use of multiple lower structural members Is to provide.

[0011] Another object of the present invention is to further enhance the pedaling safety of the floor fitness apparatus and to enable the expander band to be used promptly. In addition, the floor fitness device allows unnecessary lower structural members to be stored under the tread.

[0012]

According to the present invention, the above object is solved by a tilt-prevention type floor fitness apparatus having the features of claim 1.

According to the invention, the above-mentioned another problem is solved by a floor fitness device having the features of claim 7.

[0014]

The tilt-prevention type floor fitness apparatus of the present invention can adjust a large tilt angle for the purpose of, for example, ski land training, in which case all safety technical requirements are satisfied.

Another floor fitness device in accordance with the present invention can be assembled to a maximum step height with fewer lower structural members, thus providing increased immobility. This advantage is achieved by a downwardly extended end surface in the tread, so that the tread has the general shape of a bench. This shape, with its central high position, simply pushes the lower structural members that are not needed for the training cycle underneath the tread, thus eliminating the trip points caused by the surrounding lower structural members. Gives the advantage of.

Further advantages are obtained with the arrangements according to claims 9 and 10. Placing the anchors for the expander band in the recesses on the outer surface enables a quick and optimal finding of the anchors and ensures a fast progress of the fitness program during joint training. The expander band is secured to a hook or clip fastener depending on the configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the construction of a floor fitness apparatus 1 according to the present invention will be described with reference to FIG. The tread 2 has a vertically long shape, and the shape is similar to a footrest. A slight recess 25 is formed on the manufacturing side in the region of the tread surface 23, and a sliding mat 26 can be attached in this recess. The tread 2 has transitioned to a loose bend 27 at the end face 21, which bend then continues vertically. A projection 28 is arranged on the lower edge 22 of the end face 21 or on the longitudinal side or side wall 4 following it. The arrangement of the protrusions 28 can be seen at all four corners of the tread 2. In the horizontal position, these four projections 28 support the footboard 2. When the lower structural member 3 is not used, the tread 2 is used as a platform for sitting or lying down training, for example a holding member 30 formed in the recess 29 is also not shown. It can be used to hang expander bands.

The main feature of the present invention is that there is an arcuate bearing surface 5 formed in the side wall 4 starting from the end face 21, the bearing surface 6 being the bearing surface 6 of the lower structural member 3. Has a predetermined relationship with. This will be described in detail later.

The next main feature of the invention is the longitudinally extending longitudinal section 31, which extends upwards from the radius end 14 and thus forms the deepest point 13.

The lower structural members 3 need to be compatible with each other, which is obtained by the inner radius 11 being equal to the outer radius 12. Therefore, also in this case, the lower structural members 3 can be stacked up to a desired height.

By the way, as shown in FIG. 4, for example, when three lower structural members 3 are stacked and the tread 2 is inclined, the radius 7 or the center 8 of the tread 2 or the arc-shaped support of the tread 2 is provided. The surface 6 rotates about a fulcrum 9 formed by the foot 28 of the footboard 2. The basic effect of the present invention is that the radius 7 of the arcuate bearing surface is equal to the radius 12 of the lower structural member 3, but only forms an arc portion with respect to the latter and therefore the lower structure. The arc length L of the member 3 is smaller than the arc length L'of the lower structural member 3. This is achieved by the deepest point 13 at the radius end 14 being higher than the lower edge 22 in the region of the end face 21.

In this way, the bearing surface 5 is always in contact with the support surface 6 of the lower structural member 3 by means of a shape connection, rather than a point contact between the footboard 2 and the lower structural member 3 when they overlap.

As already mentioned, the floor fitness device 1 according to the invention comprises an upper tread 2 and preferably a plurality of lower structural members 3. By arranging the lower structural member 3 under the tread plate 2, it is possible to obtain a variable tread height. This is adjusted for each workout. To that end, the upper footboard 2 has a bearing surface 5, which is formed in the side wall 4. This bearing surface 5
Is equal to the support surface 6 of the lower structural member 3. Lower structural member 3
Are also associated with each other with their supporting surfaces 6, so that they are held securely one above the other. When there is no agreement between the upper lower structural member 3 and the tread 2, that is, between the bearing surface 5 and the support surface 6 with respect to the course of the arc and the radius section, it is indicated by symbol P in FIG. As you can see, you can only get point contact. As a result, when the user puts too much load on the footboard 2 in the direction of the arrow Q substantially on the end surface of the footboard, the footboard leaves the fulcrum P and performs a tilting motion in an attempt to find a fulcrum at an opposite position of the point P. . The result would be a terrible fall.

The same result is obtained if the side wall 4 follows the radius end 14 and runs parallel to the tread surface 23. This state is shown in FIG.

In this case, that is to say, the lower edge 24 rests on the supporting shoulder 17 of the lower structural member 3 and again forms a point contact P.

However, according to the present invention, the arcuate bearing surface 5 of the upper tread 2 has the same radius 7 as the radius 12 of the lower structural member 3, but the arc length of the lower structural member 3 is increased. It is intended to be configured as an arc portion having an arc length L smaller than L '. The radius 7 and the center 8 of the bearing 8 are notched in the arc shape of the upper tread 2 by drawing a circular locus 10 around the same outermost fulcrum 9 in each inclination. With the almost arbitrary inclination achieved by the structural member 3, it is held in the uppermost lower structural member 3 in each case so that it is not tilted by the form connection, and at the rounded end 14 of the arcuate bearing surface 5 the deepest side wall 4 is provided. Due to the presence of only one point, the entire arc length L of the arcuate bearing surface 5 of the tread 2 is retained on the support surface 6 of the lower structural member 3 by means of a form connection. This deepest point 13 is the support shoulder 1 of the lower structural member 3 at each slope.
Have a distance from 7. As the axial fixing between the lower structural member 3 and the tread 2, a raised portion 15 lifted onto the support surface 6 of the lower structural member 3 is used, and the raised portion is an end surface 16 of the lower structural member. It is located at a distance from and behind the side wall 4 of the tread 2 and below the tread.

The floor fitness apparatus according to the invention shown in FIGS. 7 to 10 comprises a known rectangular box-shaped footboard 1'and a lower structural member 2 '. The lower surface of the tread 1'is either extended downwards or pulled down in the region of the end face. This extension 4'forms a stand surface. The central portion 6'of the lower surface is in the high position. Another lower structural member 2'can be arranged below the stand surface 4 '. The tread 1'is supported by an arcuate notch 5 '. Depending on the arrangement of the lower structural member 2 ', the state of the tread is horizontal or inclined. Recesses 7'and 9'exist on the outer surface 3'of the tread 1 '. A hook-shaped receiving portion 8'for fixing an endless expander band is arranged in the recess 7 '. FIG. 10 shows a recess 9'suitable for fixing the expander band with a clip fastener. These have ridges 10 'of narrowing cross section for fastening clip fasteners in the front region.

In addition to the fastening methods mentioned here, there are also holders and fasteners known in the art for the expander band.
