Backpack and floor mat Description

The invention relates to a backpack, in particular a backpack for accommodating a folded floor mat, as well as a corresponding floor mat.

Common floor mats, such as sleeping mats, are usually made of a one-piece, cushioning material and can only be made into a transportable size by rolling them up. Floor mats of this type therefore usually do not fit in a normal backpack and are often attached to the outside back of the backpack for transport.

Athletes in particular like to use a floor mat to perform exercises lying, sitting or kneeling on it. These exercises are preferably carried out between running sessions in a running training session in order to combine cardiovascular training with strength stretching exercises.

However, carrying a backpack with a floor mat attached to the outside is quite a hindrance for athletes when power walking or jogging, as the movement, especially of the arms, is significantly restricted when running.

There are also no backpacks that can hold the well-known floor mats in such a way that they do not hinder athletes during running training. Firstly, the well-known floor mats have large external dimensions, so that it would be necessary to use a fairly large backpack, which, due to its dimensions alone, is not suitable for taking along to a running training session. Secondly, the weight of such a large backpack is not suitable for running training.

The object of the invention is therefore to provide a backpack and a floor mat which are light and simple in design, so that athletes in particular can easily take this backpack, in which the floor mat is arranged, with them to a running training session.

This object is achieved according to the invention with a backpack having the features of claim 1. A floor mat according to the invention is characterized by the features of claim 19.

According to the invention, the backpack has an interior space for accommodating a folded floor mat with an interior volume that is determined by a predeterminable width, height and length of the interior space. The width of the interior space essentially corresponds to the width of the folded floor mat.

Because the width of the interior is essentially the same as the width of the folded floor mat, the folded floor mat can be inserted into the backpack with only a small amount of play between the inner walls of the backpack and the outer sides of the folded floor mat. This has the advantage that the dimensions of the backpack are tailored to the folded floor mat and therefore, particularly in terms of its outer width, are no larger than necessary to offer the athlete maximum freedom of movement during running training with the backpack.

Depending on the design of the backpack according to the invention, the width of the interior can be between 1 cm and 25 cm, preferably between 5 cm and 10 cm, depending on the width of the folded

.:. ·· ·· - ·. ·· D33G031

Floor mat. In a special design, the width of the interior is just 6 cm to 7 cm.

In a further embodiment, the interior of the backpack has an area in which a drinking bag is arranged. This allows the athlete to conveniently drink liquid during his running training via a tube connected to the drinking bag, whereby the drinking bag can contain not only mineral water but also the drinking liquids commonly used in sports. The drinking bag preferably has a capacity of at least 0.3 liters of drinking liquid.

Furthermore, in one embodiment of the invention, the width, height and length of the interior are designed in such a way that the insertable floor mat completely takes up the interior volume of the backpack. This allows the size of the backpack to be significantly reduced in order to provide the greatest possible freedom of movement during running training.

Furthermore, at least one shoulder strap is preferably attached to the back of the backpack. For example, this shoulder strap is designed in such a way that it is arranged diagonally across the person's chest when the backpack is being carried by the person. However, two shoulder straps are also preferably provided. For example, the individual shoulder strap or at least one of the two shoulder straps is separated at one point. The sections separated in this way can be connected and separated again using a Velcro fastener. The use of such Velcro fasteners has the advantage that the athlete can, if necessary, very easily and conveniently remove the backpack from his back by opening the Velcro fastener and then buckle it back on.

In a preferred embodiment of the backpack according to the invention, a chest strap is detachably arranged on one side of the backpack. This ensures, in addition to the shoulder strap(s), that the backpack sits securely on the back. Because the chest strap is detachably arranged on the side of the backpack, it can be easily removed from the

D33G031

-A-

The chest strap can be removed from the backpack and then reattached there. This design is ideal for attaching a heart rate monitor. Because the chest strap is detachable from the backpack, the athlete can tie the chest strap around their chest at any time and measure their heart rate during running training or other training methods.

In addition or as an alternative to the chest strap mentioned, the backpack according to the invention preferably has a waist belt which enables the backpack to be carried safely.

Furthermore, it is preferably provided to detachably arrange a pocket on the chest strap in which sports equipment, such as rubber bands for stretching and strength exercises (e.g. therapy bands), and other equipment such as keys, wallets, notepads, etc. can be stored. Because the pocket is detachably arranged on the chest strap, it can be very conveniently and conveniently detached from the chest strap and reconnected to it at any time.

In a further embodiment of the invention, such a pocket is arranged on the shoulder strap or on one of the shoulder straps or on the waist belt. It preferably has the same features as those provided for the pocket on the chest strap.

In a preferred embodiment of the backpack according to the invention, a back spacer is provided. The back spacer has a bendable element attached to the backpack, for example in the form of a metal sheet, which bends the back of the backpack in such a way that it is at a significant distance from the back of the person wearing the backpack. This prevents heat build-up in the athlete's back area, particularly during running training. A detachable arrangement of the back spacer on the backpack is particularly advantageous, so that the back spacer can be easily removed from the backpack and also reattached to it.

D33GO31

Furthermore, a holder is preferably detachably arranged on the backpack, with which the backpack can be detachably attached to a bicycle. This holder, for example in the form of a hook that grips sections of the luggage carrier or frame, thus enables the backpack to be easily transported on a bicycle, whereby the holder, similar to the back spacer above, can be easily removed from the backpack and attached to it again.

Furthermore, it is intended to arrange a pocket for storing a training plan, preferably on the surface of the backpack. It is advantageous to make this pocket quite narrow and to only store the training plan, so that nothing else can be stored in this pocket. This ensures that the dimensions of the backpack according to the invention and thus its weight are kept as small as possible. In this particular embodiment, it is advantageous that the training plan is kept in a separate place that the athlete knows. He can therefore access a training plan that may be individually tailored to him without having to search for a long time.

The training plan is preferably downloaded from a database using a computer via the Internet before starting training. All of the athlete's data is stored in this database. Using this data, a sports coach creates a training plan that is individually tailored to the athlete and is continually updated.

In a further embodiment of the invention, at least one receiving means for receiving at least one liquid container is arranged on the surface of the backpack. Preferably, two receiving means for receiving liquid containers, in particular drinking bottles or drinking cans, are attached. Because these receiving means are attached to the surface of the backpack, the athlete can access them very easily. This embodiment ensures that the interior volume of the backpack is completely filled by the floor mat alone. This automatically leads to a small dimension and a lower weight of the backpack.

Furthermore, it is preferable to arrange light-reflecting elements on the surface of the backpack. These ensure that the athlete is recognized in good time by other road users, particularly in the dark or in poor visibility conditions.

According to the invention, the foldable floor mat has at least two rectangular chambers separated from one another by narrow, elongated regions, the chambers being arranged in relation to one another in such a way that the narrow, elongated regions form a grid-like pattern that extends over the entire surface of the floor mat, and a damping material being introduced into each of the chambers. The chambers are preferably all the same size.

The design of the floor mat in the form of separate chambers containing cushioning material and separated from each other by narrow, elongated areas has the advantage that the latter act as folding lines along which the floor mat can be easily and conveniently folded up. The laborious rolling up of the mat described above is no longer necessary. Furthermore, the folded floor mat has a surface the size of just one chamber due to the grid-like pattern formed by the narrow, elongated areas. It is therefore much more manageable than a rolled-up mat and can easily be stowed in a backpack, for example. The cushioning material allows you to sit or lie comfortably on the floor mat.

In one embodiment of the floor mat according to the invention, at least one holding means is arranged on one side of the floor mat. For example, a loop is provided. By lifting the folded floor mat by this loop, the mat unfolds in a simple manner without any further action.

The invention further relates to a training device comprising a backpack which has at least one of the above-mentioned features and in which a floor mat is arranged which has at least one of the above-mentioned features with regard to the floor mat. This has the advantage that the

·· D33GO31

Athletes have such a system in the form of a training device with which they can combine running training with gymnastic exercises, such as strength and stretching exercises, in a comfortable and practical way. They do their gymnastics on the floor mat according to the invention. During the subsequent running training, they pick up the backpack according to the invention, in which they can easily and conveniently store the necessary utensils and the floor mat according to the invention, whereby the backpack hardly hinders them during running training due to the design described above.

Figure 3 is a further schematic representation of the backpack according to Figure 1;

Figure 4 is a schematic representation of the opened backpack according to Figure 1 or Figure 3 with an inserted floor mat according to the invention; and

Figure 5a/b shows an unfolded floor mat according to the invention in plan view and the floor mat in a folded arrangement.

Figure 1 shows an embodiment of the backpack 1 according to the invention with a pocket 6 arranged on the outside of the backpack 1 for holding a training plan, the backpack 1 being opened and closed by means of a zipper 8. The arrangement of the pocket 6 on the outside has the advantage that the training plan is easily accessible to the athlete without him having to open the backpack 1. Furthermore,

D33G031

on the outside, two receiving means 7 are attached for receiving liquid containers, in particular drinking bottles, which in this embodiment are designed like a basket. The liquid containers can be inserted into these receiving means 7 and held in the receiving means 7 by means of a loop 18 which surrounds them and is attached to the receiving means 7 in conjunction with a conventional clamp 19, which prevents the liquid container from slipping out, for example during running training.

Figure 2 shows a schematic representation of the internal volume 2 of the backpack 1. The reference number 3 designates the width of the backpack 1, the reference number 4 its height and the reference number 5 its length. The width of the backpack 1 essentially corresponds to the width 20 (cf. Figure 5b) of a folded floor mat which is arranged in the backpack 1.

Figure 3 shows further elements of the backpack 1 not shown in Figure 1. Two shoulder straps 9 are attached to the back of the backpack 1, which are additionally connected to one another via a connecting element 10 in the form of a connecting belt. This connecting element 10 increases the hold of the backpack 1 on the athlete's back. Furthermore, the weight of the backpack 1 is transferred to the athlete's back via a larger contact surface, which is particularly advantageous when the backpack 1 is worn for longer periods. As described above, a chest strap 11 is also detachably attached to the back of the backpack 1, but this can also be designed as a waist belt. A pocket 12 is detachably attached to the chest strap 11, in which a theraband or other objects can be stored, for example.

Furthermore, reflective strips 21 are arranged around the sides of the surface of the backpack 1. These reflective strips 21 serve to ensure the safety of the person carrying the backpack 1 at night.

mat 13 in plan view, with the chambers 15 containing damping material. The chambers 15 are separated from each other by narrow, elongated areas 16 and serve as folding lines. The floor mat 13 can be folded up in such a way that it takes on the shape shown in Figure 5b. In this folded up form, the floor mat 13 can be easily inserted into the interior of the backpack 1.

A loop 17 is attached to the floor mat 13 for removal from the backpack 1. By taking the loop 17, the floor mat 13 can be pulled out of the backpack 1, whereby the floor mat 13 automatically unfolds and can be placed on the floor for carrying out exercises.

The backpack 1 according to the invention has the advantage that the width 3 of the interior or interior volume 2 essentially corresponds to the width 20 of the folded floor mat 13. In this way, the folded floor mat can be inserted into the backpack with only a small amount of play between the inner walls of the backpack 1 and the outer sides of the folded floor mat 13. The dimensions of the backpack 1 are thus matched to the folded floor mat 13. It is therefore not larger than necessary, particularly with regard to its outer width, and guarantees the athlete maximum freedom of movement during running training with the backpack 1.

Furthermore, the height 4 and the length 5 of the backpack 1 are also adapted to the dimensions of the floor mat 13. The floor mat 13 is completely accommodated in the backpack 13 in such a way that the interior volume of the backpack 1 is completely filled and no further objects can be brought into the interior of the backpack 1.

The training means described, consisting of the floor mat 13 according to the invention and the backpack 1 according to the invention in which the floor mat 13 is arranged, is very handy and light. The width of the backpack 1 is generally between 6 cm and 7 cm. The weight of the backpack 1 with the floor mat 13 arranged therein is preferably 0.8 kg.

The floor mat 13 according to the invention eliminates the cumbersome rolling up of the floor mat that is common with floor mats according to the prior art. Furthermore, the folded floor mat 13 has a surface the size of only one chamber 15 due to the grid-like pattern formed by the narrow, elongated areas. It is therefore much more manageable than the rolled-up floor mat and can be easily stowed in the backpack 1. The cushioning material enables comfortable sitting or lying on the floor mat.

In the backpack 1 according to the invention, it is also provided to arrange a back spacer (not shown). By means of this back spacer, the person's back is at a significant distance from the backpack. This prevents heat build-up in the athlete's back area, especially during running training.

There is also a bracket (not shown) with which the backpack can be attached to a bicycle. This bracket allows the backpack to be easily transported on a bicycle.
