Glove with integrated spring, spiral, wave or ring as a protective device to dampen or prevent vibrations

-2-

The invention relates to gloves of all kinds as protective devices for damping or preventing vibrations by integrating one or more waves, spirals, springs or rings in different layers, lengths, diameters and materials.

Every day, hand- and arm-operated tools or objects in general are used all over the world with the intention that the collision of the striking object with the object being struck will change the direction of movement or that the shape of the object will change or that the striking object will be integrated into another object. * '"' "

From this variety of practical applications, the following examples can be given: hitting a nail with a hammer, hitting a piece of wood with an axe, or from the field of sport, hitting a tennis ball with a tennis racket, a baseball with a baseball bat, or using tools and machines that cause shocks and vibrations of various kinds.

When handling tools, people clearly feel the vibrations and shocks when the striking object held in their hand hits the striking object. The resulting vibrations travel from the point of impact of a tool or striking object back into the hand and then into the arm.

The new type of device is intended to absorb this vibration.'

From a practical perspective, we take the profession of a street worker as an example."
It is well known that the constant daily hammering of a compressed air tool releases vibrations that cause the carpal bones of these people to become inflamed, which in the worst case leads to an occupational disease with consequences of joint deformities.

There are a variety of options available to prevent the hands and arms from becoming inflamed, for example, if there is inflammation, spraying the arms with a cooling spray, wearing a tight bandage around the forearm or applying an ointment that allows the area to be well supplied with blood.

In addition, when using tools, people try to avoid this vibration by wearing gloves and the resulting calluses and blisters on their hands.

The invention is therefore based on the task of designing gloves in such a way that they are easy and problem-free to handle and that they absorb the vibration by integrating or subsequently adding a wave, spring or spiral or at least dampen it so that the vibration after the impact does not flow back into the hand and thus further into the aim of the person holding the striking object. Shocks and vibrations affect people's performance. If these vibrations are not isolated, they cause premature damage.

The gloves according to the invention solve the above problem.

The shape and design of gloves with a wave, spring, ring or spiral are not only intended as a protective device for the hand and arm, but also have another use. The use of integrated vibration dampening has the effect that the objects being struck can be struck more forcefully due to the vibration dampening. This results in a higher impact speed and therefore makes it possible to achieve the same result with less force or to achieve a clearly better result with increased impact force.

In the cases of vibration dampening described above, the vibration is absorbed by the shape and arrangement of the wires and springs and is no longer or only partially absorbed and passed on to the handle. In this case, the incoming recoil in the form of a natural vibration, which normally leads to transmission to the executing organ (arm and hand) without the integration of our device, is literally cushioned. The inside of the glove must be lined with a stable, vibration-resistant mat.

The following describes features that relate to the detailed structural design of the gloves.

A shaft (Fig. 2 ), whether flexible or rigid, is a structure made up of different wires with different wire thicknesses and permanently rotating wire connections in different wound layers of round wire or flat wire.

The variety of windings made of flat or round wire with an inner steel cable or inner guide wire, e.g. spring steel wire, with different materials also results in different quality classes and different effects. It can therefore be assumed that the length, type and structure of a spring and flexible shaft increases or decreases the vibration of the object. The shaft is stronger than a spring.

Just as the flexible shaft is a product with multiple transformation possibilities, the following examples also leave open whether one or more flexible shafts (Fig. 2), springs (Fig. 3), rings (Fig. 5 and 5a) or spirals (Fig. 4) are used for the respective glove. The choice and construction of a "specific device depends, to name a few examples, on the intended use of the glove, the duration of the load, the shape of the glove, the size of the vibration damping or the shock and impact damping, the acceleration peak and the impact speed, the pulse duration and the bending stress. ■ ■

According to the invention, it has been recognized that the glove, due to the various features of the glove and the forms of application and questions such as impact intensity, shape of the tool, for which purpose the glove is used, the various forms of the integrated flexible shafts, spirals, rings or springs must be used in such a way that optimal vibration damping is achieved.

The integrated components are therefore different. In this sense, depending on the type of glove, the question is whether a flat or round spiral should be used, or whether a flat spring, conical spring, cylinder spring, cylinder with leaf spring, compression spring or a round spring with inner core wire should be used. Depending on the need, the shaft or spring can also be made into other shapes such as triangular or polygonal.

The possibility of a connection using plastic-injected springs, with plastic wires or other windable ropes must also be taken into account in the requirements profile of the glove.

It is also practical to provide a vibration-damping device for only part of a glove, such as one or two fingers or just the palm.

Since signs of wear and tear can often occur with such shafts after prolonged use, it would be advantageous if the integrated shafts, springs, rings and spirals could be removed from the glove so that new ones could be inserted.

In a particularly advantageous manner, the device should not only be installed as a new glove, but should also be able to be subsequently inserted or attached to existing gloves as an insert.

The shafts, springs, rings and spirals can have different sizes, lengths, diameters and shapes, depending on the glove for which they are used.

According to a particularly advantageous design of a glove, in addition to the usual dampening options such as gel, plastic, rubber or other natural products, springs, rings, spirals or waves can be integrated into these materials.

In order to achieve a better impact, not only the palm of the hand and the fingers could be provided with a dampening device in the form of a flat wire compression spring (Fig. 3) or a wire rope spring (Fig. 7), but also the wrist and the entire forearm could be provided with spring or spiral elements. It is advantageous if the dampening device is made of a particularly light material such as aluminum, so that the glove does not gain too much weight due to the integration of a dampening device.

The device could also be integrated into the glove and arranged in front of the inner surface in the form of knobs (Fig. 9).

Regarding the material used to manufacture the flexible shafts, springs and spirals, it is advantageous for cost reasons if these are made of metal. However, it is also possible to manufacture them from plastic, metal, rubber or natural fibers. It is also possible to manufacture a vibration damping device from a combination of different materials such as plastic and metal.

The type of shafts, springs, rings and spirals can vary greatly depending on the type of shock absorption or vibration damping and the corresponding area of application. They can be made of single springs with an integrated spring, of single or multiple wires, with or without compression and tension springs, as flat wire (Fig. 3) or disc springs, as torsion or shaped springs, as wave springs (Fig. 6) or wire rope springs (Fig. 7), as partial or full shafts or even as flexible shafts (Fig. 2), which can also be single or multi-layered, and all of this without fixed shapes.

Depending on the use of the gloves and the wide range of options for vibration dampening described above, the integration of a wave spring and a wire rope spring should be highlighted as an example.

From the drawing (Fig. la) it can be seen that the wave spring (Fig. 6) consists of several layers in the form of corrugated rings. Integrated into a glove, the vibration is absorbed by the vibration compressing the wave spring. The second shock absorption is provided by the wave spring slowly springing back again.

A second example is the representation of a wire rope spring (Fig. 7). The wire rope spring is mostly used in the transport system. The vibration and shock damping in this graphic representation is particularly intended for lateral damping. The bundled spirals are attached and connected on both sides.

The area of application for the new glove is very extensive. To name a few examples, it is particularly used in the sports sector, such as for mountain bikers, motorcyclists, ice speed riders, racing boat drivers, bobsledders or racing drivers.

■For road construction workers, the glove should be used especially when working with the jackhammer device.

It should then be emphasized that the teaching of the present invention, the design of a glove in the sense that the vibrations are reduced or no longer resonate back into the leading hand, has not been restricted by the above-described embodiments, but rather has only been described and that all types of gloves are meant.
