[0001] The present invention relates to a glove in accordance with the introduction to the
main claim. It relates in particular to a glove to be used in automobile sporting
competitions.
[0002] In automobile racing there is a known serious risk of fire; this is mainly because
of the high level of car performance and the presence close to the driver's compartment
of the fuel tank feeding the engine. Fire danger is also considerable in the case
of collisions or accidents of any type.
[0003] The severe competition rules require that the drivers' clothes be made of flame retardant
fabrics which protect the driver in all situations. A well known type of such frame
retardants is marketed under the name of NOMEX. It provides considerable flame protection
but has the great drawback of being very prone to slippage.
[0005] The problem does not arise when used to form frame retardant suits or other types
of clothing. However when used to form gloves it creates considerable problems.
[0006] In fact drivers find it difficult to accept the considerable material slippage which
makes the steering wheel grip very insecure.
[0007] Moreover on using frame retardant fabric, drivers complain of considerable problems
deriving from the vibration which such material transmits to their hands.
[0008] An object of the present invention is therefore to provide a glove representing an
improvement over the known art.
[0009] A further object of the invention is to provide a glove presenting a very reliable
grip without slippage.
[0010] A further object of the present invention is to provide a glove which considerably
dampens the vibrations transmitted to the driver's hands through the glove.
[0011] These and further objects are attained by a glove in accordance with the technical
teachings of the accompanying claims.
[0012] Further characteristics and advantages of the invention will be apparent from the
description of a preferred but non-exclusive embodiment of the glove of the present
invention, illustrated by way of non-limiting example in the accompanying drawings,
in which:
Figure 1 is a plan view of the palm of a glove of the present invention;
Figure 2 is a perspective view of a portion of the palm of the glove of the present
invention, showing the micro-craters of a glove cladding;
Figure 3 shows the operation of the micro-craters of Figure 2 when subjected to a
pressure;
Figure 4 shows the operation of a single micro-crater when subjected to a considerable
pressure;
Figure 5 shows the operation of a single micro-crater when subjected to a light pressure;
Figure 6 shows in plan a plurality of micro-craters and the lines along which air
circulates between them; and
Figure 7 is a plan view of the rear of the glove of the present invention.
[0013] With reference to said figures, these show a glove indicated overall by 1.
[0014] The glove 1 comprises an element 2 shaped as a hand to form the base structure of
the glove. To this base element, formed of a frame retardant fabric commercially known
as NOMEX, a plurality of portions of cloth 3, 4, 5 or other material are sewn, in
particular to obtain aesthetic effects, such as sponsors, trademarks 3 or decorations,
and functional effects such as protections 4 and anti-abrasion material 5. In particular,
a protection element 5 is applied across the knuckles. Another protection 4 is sewn
onto the index finger and also at the joint between the wrist and hand on the rear
9.
[0015] A cladding is applied to the base element 2 on the palm 8 (see Figure 1) in a plurality
of palm regions 7. These regions 7 are substantially the glove gripping/resting regions.
This cladding is formed of a deformable spongy material of any type, but preferably
of a flame retardant material known commercially as HOTTEX.
[0016] This cladding is given a configuration in the form of spaced-apart micro-craters
20, as shown in Figure 2. It should be noted that for simplicity of representation
these micro-craters 20 are shown in Figure 1 only in the initial regions 7A present
on the glove index and middle finger, however they are also present in all other regions
7 shown in Figure 1.
[0017] In particular the craters are present in initial gripping regions 7A on each of the
fingertips/second phalanx of the glove fingers. These initial regions 7A present a
first and second wider portion 11, 12 located at a first and second phalanx of each
finger; between said wider regions 11 and 12 a narrower portion 13 is present.
[0018] The micro-crater cladding 20 is also applied to a second gripping region 7B at the
connection portion between the body of the hand and some of the fingers. This portion
presents a transverse band 14 from which four segments 15 extend towards the fingers
to each involve a portion of each finger.
[0019] A third cladding region 7C is also present disposed in an intermediate position of
the palm. This third region presents the shape of a band elongated in a direction
transverse to the palm of the glove and comprises a segment 15 extending from it along
the index finger.
[0020] The micro-craters 20 are also provided on a fourth gripping region 7D which extends
from that portion 16 by which the palm of the hand is joined externally to the wrist,
towards the centre of the palm.
[0021] The micro-craters are also provided on a fifth and sixth gripping region 7E of substantially
trapezoidal shape positioned in a region below the wrist in the outer portion of the
forearm and in the inner portion of the forearm straddling the wrist. Below each trapezoidal
region 7E seventh regions are provided comprising micro-craters. These seventh regions
each present two extended portions 110, 120 of a shape similar to those provided on
the phalanxes, interconnected by a region 130 of lesser extension.
[0022] The micro-craters present in the listed regions are schematically represents in Figures
from 3 to 6. Specifically, each of the micro-craters 20 presents a substantially frusto-conical
shape, with the major base secured to said base structure 2. At their top. each of
the micro-craters 20 presents a dead-ended concavity 21 of rounded profile able to
deform elastically when subjected to even a minimum pressure, such as that arising
by merely resting the hand on the steering wheel. The operation of the micro-craters
is well evident in Figures 4 and 5.
[0023] Figure 4 shows a micro-crater 20 stressed by a considerable force, such as the gripping
force exerted on the steering wheel by a tight fist during a sporting competition.
Elastic deformation hence takes place both of the crater region comprising the cavity
or hollow 21 and of the crater trunk. Hence the crater provides optimal damping and
protection against vibrations and an optimal grip on the steering wheel. In particular,
damping is provided by the elastic deformation of the crater trunk.
[0024] At points in which the pressure is less, where the hand only rests, the micro-crater
is deformed as in Figure 5, i.e. is deformed only in its initial part comprising the
cavity or hollow 21, the crater trunk 20A remaining undeformed. This results in an
extension of the contact surface between the gripped object and the glove, to ensure
an optimal grip, the contact surface between the glove and object being considerable.
[0025] In the present text the term "deformable" is widely used, referring to the constituent
material of the micro-crater cladding. The deformability of this material is such
as to obtain a deformation such as that described, and in particular of just the initial
part when the crater is subjected to the force of the glove on the steering wheel,
and also of the second part if vibrations or gripping forces are present on the steering
wheel during a competition. When the stress on the craters ceases, their constituent
deformable material returns elastically to its original position, to reconstitute
the basic shape of the craters before being stressed.
[0026] Essentially, the micro-craters 21 conceived in this manner increase the gripping
friction while simultaneously damping any impact or vibration by their deformation.
[0027] Advantageously, as each micro-crater is spaced from the others, considerable air
circulation can take place between their bases, facilitating heat transfer and reducing
perspiration precisely in those points where the pressure is a maximum (see Figure
6 which shows this air circulation by arrows F). Advantageously, as well visible in
Figure 2, the micro-craters present in certain gripping regions, such as 7D and 7C,
have a different radius and/or height and/or density in order to absorb different
vibration types.
[0028] In Figure 1, in each of the described regions 7 differently coloured sub-regions
are visible. In the dark black regions the craters are low, in the dark grey regions
the craters are slightly higher, while in the white regions in the centre of the parts
indicated by 7C and 7D they attain their maximum height. These are in fact the most
stressed regions. Advantageously craters of different density materials can be provided,
a different density possibly being provided for each crater region, based on the regions
in which the craters are positioned.
[0029] In particular, in Figure 2 it can be seen that the micro-craters present a distribution
such that the micro-craters of greatest diameter and height are positioned in the
central portions (the most stressed, i.e. the white parts of Figure 1 within the regions
7D and 7C) of the gripping regions 7; the micro-craters also present a diameter and/or
height which decreases in the direction away from the centre of each gripping region
7 (black regions in Figure 1). A preferred embodiment has been illustrated, however
others can be conceived using the same inventive concept. For example, the micro-crater
distribution can be of any type required to properly adapt to the different pressure
profiles predictable within the grip for which the glove is intended (steering wheel,
etc.). Moreover the micro-craters can have any shape. They are represented here as
of frusto-conical shape, however they can also be cylindrical, of circular, square
or any base.
[0030] The same micro-crater can also be made of different density materials. For example
the initial part can be of low density Hottex to give it considerable deformation,
while the second support part can be of greater density Hottex.
