Description
The present patent application consists, as its
title indicates, of "Pincers for extracting fuses and
relays", whose new characteristics of construction, shape
and design fulfill the object for which they have
specifically been planned, with maximum safety and
effectiveness and with many advantages, as described
below.
Normally, the operation of extracting a fuse from
the fuse box in which it is inserted is difficult and
uncomfortable. Often, it cannot be done with the fingers.
When the fuse is arranged in the fuse box, there is
no space between the body of the fuse and the edges of
the fuse box in which to operate and extract said fuse.
When a fuse has to be replaced in maintenance
operations of the electrical system of, for example, a
vehicle, tools and implements are usually used that are
often not appropriate, which results in the fuse body
breaking and the fuse being rendered useless. Moreover,
if the fuse body breaks while it is still inserted in the
fuse box, its extraction becomes complicated, since there
is insufficient base for holding it in order to extract
it.
In the prior art, solutions have been proposed, such
as the use of pincers for extracting fuses, which
typically comprises a body which is basically U-shaped
and defines a first pair of arms, and a second pair of
arms joined to said body in the joining area of said
first pair of arms. This body is made of plastic material
so that the ends of both pairs of arms can be brought
together in order to work as pincers. Said ends of the
first pair of arms of conventional pincers have a slot
which serves to hold the end of a small fuse. The free
ends of the second pair of arms have a slot which serves
to hold the end of a large fuse.
This type of pincers allows fuses of two sizes to be
handled effectively and simply. However, in the market
there are currently three types of fuses according to
their size: large fuses, medium-sized fuses and small
fuses. Thus, if fuses of the three types are fitted in
the electrical system of, for example, a vehicle, users
must necessarily use a minimum of two pincers of the type
described if they wish to handle said fuses. In the event
that the pincers to be used are made up of two pairs of
arms, of which only the ends of one pair are provided
with said slots, users (or operators) will have to use
three kinds of pincers, one for each fuse size.
The present invention has been developed in order to
resolve this drawback, by providing universal pincers,
capable of coupling with the different types of pincers
currently existing in the market. The pincers that are
the object of the present invention provide other
advantages which will be made clear hereinbelow.
In general terms, the pincers for extracting fuses
and relays in accordance with the present invention are
of the type mentioned above, that is, made up of a
basically U-shaped body that defines a first pair of
arms. The body of conventional pincers also comprises a
second pair of arms joined to said body in the joining
area of said first pair of arms. The free ends of said
first pair of arms have a slot for holding the end of a
fuse, while the free ends of said second pair of arms
have a slot for holding the end of a larger fuse.
The peculiarity of the pincers of the invention lies
in the fact that at least one of said pairs of arms
includes a slot at its free end for holding the end of a
relay. These transverse slots are made approximately in
the central area of the free end of said second pair of
arms.
Additionally, the free ends of the two arms of said
first pair of arms have two parallel projections which
define a small channel which extends perpendicularly with
respect to said slot of the arms of said first pair of
arms and which are adapted to be housed in slots in the
body of a fuse. The arrangement of these projections
allows the first pair of arms to extract fuses of two
different sizes which, together with the fuses which may
be extracted by using the second pair of arms, make three
different types of fuses which may be handled with the
pincers of the present invention. The combination of said
projections and said slots make the pincers of the
present invention versatile, since relays can also be
handled by means of the same, which convert the pincers
of the invention into a very useful and effective tool.
In accordance with another feature of the invention,
the free ends of the two arms of the second pair of arms
have two parallel projections adapted to be housed in
slots in the body of a larger fuse.
Advantageously, said second pair of arms is provided
on its outer part with two series of outer ribs which are
arranged in parallel. These two series of ribs serve to
facilitate gripping of the pincers, that is, to be able
to join the ends of the first or second pair of arms of
the pincers comfortably.
In accordance with a preferred embodiment of the
pincers for extracting fuses and relays of the present
invention, the second pair of arms comprises, at its free
end, a slot which has a shape adapted to receive a
longitudinal projection with a T-shaped cross-section
made in the end of a relay.
Other features and advantages of the pincers for
extracting fuses and relays that is the object of the
present invention will be clearer from the detailed
description of a preferred embodiment of said pincers.
Said description will be given, from here on, by way of
non-restrictive example, with reference to the drawings
which accompany it, in which:
The elements which appear in the attached drawings
are the following: (1) pincers for extracting fuses and
relays, (2) U-shaped body, (3) first pair of arms, (4)
second pair of arms, (5) joining area of the arms, (6)
ends of the first pair of arms, (7) medium-sized fuse,
(8) small fuse, (9) slot of the first pair of arms, (10)
end of the medium-sized fuse, (11) body of medium-sized
fuse, (12) projections of the first pair of arms, (13)
channel of the first pair of arms, (14) inner part of the
first pair of arms, (15) slots of the small fuse, (16)
body of the small fuse, (17) end of the second pair of
arms, (18) slots of the second pair of arms, (19) end of
the large fuse, (20) body of the large fuse, (21) large
fuse, (22) projections of the second pair of arms, (23)
slots of the large fuse, (24) relay, (25) slot of the
second pair of arms, (26) longitudinal projection of the
relay, (27) body of the relay and (28, 29) ribs of the
second pair of arms.
The pincers (1) for extracting fuses and relays in
accordance with the present invention consist, in their
most general form, of a body (2) that is basically U-shaped,
which is made up of a first pair of arms (3) and
a second pair of arms (4). The second pair of arms (4) is
joined to said body (2) in a joining area (5) of the
first pair of arms (3), as may be observed in figure 1.
The first pair of arms (3) has ends (6) whose
geometry allows two types of fuses to be held: medium-sized
fuses (7) (figure 2) and small fuses (8) (upper
part of figure 3). To achieve this, the end (6) of each
arm (3) is provided with a slot (9) of approximately
rectangular shape. The combination of the slots (9) of
the two arms (3) defines a housing for receiving the end
(10) of the body (11) of a medium-sized fuse (7), such as
that represented in the upper part of figure 2.
At the same time, the end (6) of each arm (3) is
also provided with two parallel projections (12) which
define a channel designated by (13). This channel (13) is
made in the inner part (14) of the first pair of arms (3)
in such a way that it extends perpendicularly to the slot
(9) mentioned above.
Said two projections (12) of each arm (3) are housed
in slots (15) made in the body (16) of a small fuse (8)
such as that represented in figure 3.
The configuration of the second pair of arms (4) is
defined by plates arranged basically parallel to each
other, each one being joined, as described above, to the
arms (3) at the joining area (5).
The ends (17) of each of said arms (4) include a
slot (18) which is basically parallel to the slot (9) of
the arms (3). The slot (18) has the same configuration as
the slot (9), although said slot (18) is larger in order
to house the end (19) of the body (20) of a large fuse
(21), as represented in the lower part of figure 2.
As in the case of the channel (9) of the arms (3),
the combination of the channels (18) of the arms (4) (see
figure 1) allows said end (19) of the fuse (21) to be
conveniently housed, as illustrated in figure 2. This end
(10) is defined by an extension of small height that
emerges from the upper part of the body (20) of said fuse
(21), as may be observed in figure 2 of the drawings.
The ends (17) of said arms (4) have projections (22)
adapted to be housed appropriately inside slots (23) made
in the body (20) of the fuse (21) represented in said
figure 2.
The versatility of the pincers of the invention is
completed by its ability to extract relays (24) of the
type represented in figure 4.
To achieve this, each end (17) of the arms (4)
includes a slot (25) which allows a longitudinal
projection (26) of the body (27) of the relay (24) with a
T-shaped cross-section to be housed. With reference to
figures 1 and 4, the longitudinal projection (26) may
appropriately be introduced into both slots (25),
remaining in a perpendicular position with respect to the
slot (18).
As may be observed, the second pair of arms (4) is
provided on the outer part with two series of parallel
ribs (28, 29), which serve to facilitate gripping of the
pincers (1). Thus, by pressing on the ribs (28), the ends
(6) of the first pair of arms (3) are joined in order to
hold a medium-sized fuse (7) or a small fuse (8), or to
release a large fuse (21) or a relay (24). By pressing on
the ribs (29), the ends (17) of the arms (4) are joined
to hold a large fuse (21) or a relay (24), or to release
a medium-sized fuse (7) or a small fuse (8).
The materials of the elements that make up the
pincers for extracting fuses and relays of the invention,
as well as the shapes, dimensions and other accessory
elements may conveniently be replaced by others that are
technically equivalent, provided that they do not depart
from the scope of the present invention
as defined in the
claims included below.
