[0100] FIG. 3 shows a glove for vibration insulation 301. As the glove for vibration insulation 301 of FIG. 3 is in large the same as the glove for vibration insulation 1 of FIG. 1 (e.g. the same reference numerals as in FIG. 1, with the addition of the value 300 is used for corresponding features in FIG. 3), focus on the description related to FIG. 3 will be on the differences compared to the glove for vibration insulation 1 of FIG. 1. In FIG. 3 the first material 322 and the insulation material 320 is arranged to cover the little finger and the ring finger when the glove for vibration insulation 301 is in use. Still, the first material 322 and the insulation material cover at least 50% of the width of the finger covering portion 312 at the gripping side 314 of the glove for vibration insulation 301. At the other finger covering portions 312 there is solely one piece of first material 322 and insulation material 320.
[0101] FIG. 4 shows a cross-sectional view of the gripping side 414 of a glove for vibration insulation. The gripping side comprises an inner 426 and an outer surface layer 424, a first material 422 and an insulation material 420. The first material 422 and the insulation material 420 are arranged between said inner 426 and outer surface layers 424. The first material 422 is arranged adjacent to the inner surface layer 426 whereas the insulation material 420 is arranged adjacent to the outer surface layer 424. When in use, the insulation material 420 is arranged in front of said first material 422 as seen from the outer surface of the gripping surface 414. In other words, the first material 422 is placed behind the insulation material 420.
[0102] FIG. 5 shows one example of the first material 522. The first material 522 is a composite which comprises a polymer based compound and metal particles and/or metal beads. The metal particles and/or metal beads is made from tungsten. Further, the first material 522 comprises protrusions 530. The protrusions 530 have a height of 1 mm. A portion 534 of the first material 522 is not covered by the protrusions 530, this portion forms a fold 534 in the first material 522. The first material is thinned at the fold 534 as compared with the rest of the first material 522.
[0103] The protrusions 530 cover at least 1/10 of the area of the first material 522. Further, the protrusions 530 of the first material 522 is arranged to face the insulation material when in use. The fold 534 is arranged to cover the joints of the finger when in use in order to e.g. facilitate the bending the fingers.
[0104] FIG. 6 shows one example of the insulation material 620. The insulation material 620 is a foam rubber material. Further, the insulation material 620 comprises holes 642. In this embodiment there are holes 642 of two different sizes, both sizes of holes being through holes. The portion of the insulation material 620 comprising the larger holes 642 corresponds to the fold 634 of the insulation material 620. The fold 634 is arranged to cover the joints of the fingers when in use in order to e.g. facilitate the bending of the fingers.
[0105] FIG. 7 shows the relationship between the E-module for the insulation material in the glove for vibration insulation and pressure applied to the glove. When the pressure starts to increase the E-module will decrease at first and then later increase again. This means that when a pressure is applied to the insulation material the softness of the material will increase. The protrusions of the first material facing the insulation material will engage the insulation material, i.e. the pressure applied to the insulation material will be different depending on if the insulation material meets a protrusion or a void. By this engagement, the softness of the insulation material may be controlled. The solid line shows the E-module of solely an insulation material. The dashed line shows the E-module of an insulation material when in contact with a first material which comprises protrusions. The E-module of the insulation material when in contact with the first material will approach the E-module of solely the insulation material when the insulation material reaches the surface in between the protrusions of the first material.
[0106] FIG. 8 shows the relationship between the resonance of the fingers and the frequency of the vibration instrument and/or tool. The solid line corresponds to the use of a glove for vibration insulations in accordance to at least one embodiment of the invention. The dashed line corresponds to the use of a glove without the first material resulting in a much lighter glove. In the graph it can be seen that when using a glove according to at least one embodiment of the invention the resonance is lowered already at lower frequencies. Hence, the glove according to at least one example embodiment of the invention protects the fingers at lower frequencies, which frequencies otherwise would have been harmful for the fingers but not necessary for other parts of the hand.
[0107] FIG. 9a-d shows photographs of a glove for vibration insulation 901. In this embodiment the glove 901 is a three finger glove, i.e. the glove 901 comprises three finger covering portions 912,912,912 which are separated from each other. These three of the finger covering portions 912, 912,912 each comprises a first material 922 with a density of at least 1.5 g/cm.sup.3 and an insulation material 920.
[0108] The insulation material 920 is arranged in front of said first material as seen from the outer surface of said gripping surface 914. In other words, the first material is placed behind the insulation material 920 in the glove for vibration insulation 901 shown in FIG. 9a-d.
[0109] In the embodiment shown in FIG. 9 the palm covering portion 910 comprises insulation material 920. This may be the same choice of material as comprised in the finger covering portions 912 and 912 or in may be another material.
[0110] In the embodiment shown in FIG. 9a-d the gripping side 914 comprises two layers of a non-woven material 950. At the finger covering portions 912, 912, 912 the first material 922 and the insulation material 920 is arranged between those two layers of a non-woven material 950. At the palm covering portion 910 the insulation material 920 is arranged between said two layers.
[0111] As seen in FIG. 9c, the hand-back side 916 of the glove for vibration insulation 901 partially comprises two layers of a non-woven material 950 and partially a woven and elastic material 952.
[0112] FIGS. 9b and 9d shows the glove for vibration insulation from the sides. Here it can be seen that between the two layers of a non-woven material 950 of the hand-back side 916 there is pads comprising insulation material 920.
[0113] The skilled person realizes that a number of modifications of the embodiments described herein are possible without departing from the scope of the invention, which is defined in the appended claims. For instance the glove may be a five finger glove where all five fingers being separated from each other when in use. Moreover, the first material and the insulation material may be arranged differently than what is shown in the embodiments described above in order to protect the fingers in a different way. Different vibrating instruments require protection in different ways. For example, some vibrating instruments are hold as a pen, i.e. with a pen grip. This requires protection for the thumb, index finger and the side of the long finger.
