Description
[0001] The present invention relates to a piece for fixing objects
to a wall or the like.
BACKGROUND OF THE INVENTION
[0002] Pieces which are used as clamps for fixing elements to
supports such as walls, roofs and the like, which are fixed by
means of tools as nail guns, are known.
[0003] Some of these pieces have been designed to be temporarily
attached to the end of the outlet mouth of said guns to allow the
user to push the piece against the wall by means of the gun before
shooting the nail, without having to hold it with both hands. Once
the nail has been shot, the gun is detached from the piece, which
is already fixed to the wall.
[0004] Pieces are known which are provided with a central housing
in which the end of the mouth of the gun is introduced. The
attachment is carried out by friction between the piece and the
outer surface of the end of the mouth of the gun.
[0005] The process for placing these pieces in the mouth of the gun
is difficult and can involve some risk for the user, as a
considerable force has to be exerted to overcome the friction
between the piece and the outer surface of the gun. This entails
that the user has to carry out a considerable axial force to fix
the piece in the end of the gun.
[0006] The nail gun has a security mechanism, which only allows
shooting a nail if the mouth of the gun has been moved axially
until a predetermined position when it is pushed against the
wall.
[0007] Thus, there is a risk for the user of exerting enough force
to move the mouth to the shooting position when he is placing the
piece in the mouth, which may cause an accident.
[0008] To avoid this inconvenience, clamps have been designed which
shape allows coupling them laterally to the mouth of the gun.
However, these pieces have to be provided with side flanges, which
make more complex the design of the piece. The mouths of the guns
have to be provided with perimeter transversal slots for receiving
said flanges of the pieces, which increases costs when
manufacturing said elements. Moreover, attaching and detaching the
piece and the mouth is slower and more complex.
[0009] When the piece is fitted onto the mouth, the user has to
take care that the flanges are properly fitted into the slot of the
mouth, and the operation to place the piece has to be more
accurate.
[0010] When the piece has been fixed to the wall and the gun has to
be withdrawn, the flanges of the piece are housed inside the slot
of the mouth, and they do not allow detaching the piece from the
gun by means of an axial movement, so the gun has to be moved
laterally. In the case that there isn't enough space for operating,
the fact of having to move the gun laterally involves, moreover, a
new inconvenience.
DESCRIPTION OF THE INVENTION
[0011] The aim of the of the present invention is to solve the
disadvantages of the devices known in the art, providing a piece
for fixing objects to a wall or the like which comprises removable
attaching means to the end of the outlet mouth of a tool for
propelling an element for fixing the piece to the wall or the like,
and means for holding the object to be fixed, characterized in that
the means for attaching the piece to the end of the outlet mouth of
the tool comprise at least a rib, which is longitudinal to the axis
of the mouth, in contact with the outer surface of the end of said
mouth.
[0012] Thanks to these ribs, the piece can be fixed to the mouth of
the gun in an easier way, making centering the piece with respect
to the axis of the mouth easier, and reducing the force necessary
to introduce the mouth into the piece due to the smaller friction
surface. Risk of accidental shots is thus avoided.
[0013] Moreover, the piece of the invention can be coupled to any
type of mouths of guns, since the ribs can be adapted to smooth or
rough surfaces.
[0014] According to an alternative embodiment of the present
invention, the piece comprises at least three longitudinal radial
ribs, each of said ribs being spaced from one another by the same
angle.
[0015] An equidistant angular separation of the ribs makes
centering the piece with respect to the outlet of the mouth of the
gun easier, allowing that the nail is driven in the center of the
piece.
[0016] Preferably, the means for holding the object to be fixed
comprise al least a perimeter window.
[0017] These windows allow passing strips or similar elements used
to bear the element hold by the piece through them.
[0018] According to an embodiment of the present invention, the
means for holding the object to be fixed comprise a pair of side
arms.
[0019] Advantageously, the piece comprises means for receiving the
element for fixing the piece to the wall.
[0020] According to an embodiment of the invention, the means for
receiving the element for fixing the piece to the wall comprise a
central cylinder in the base of the piece, said fixing element
being placed inside said cylinder.
[0021] Thanks to said cylinder, the nail is properly centered, said
element also absorbing the impact of the nail and preventing the
nail from damaging the wall and its head from piercing the
piece.
[0022] Preferably, the piece comprises attaching means to the inner
surface of the outlet mouth of the tool.
[0023] Advantageously, the attaching means to the inner surface of
the mouth comprise ribs, which are longitudinal to the axis of the
mouth, in contact with the inner surface of the end of said mouth,
said ribs being positioned at the outer surface of the cylinder for
receiving the fixing element.
[0024] Thus, the piece of the invention can also be fixed by
friction to the inner wall of the end of the mouth of the gun.

DESCRIPTION OF A PREFERRED EMBODIMENT
[0031] The piece 1 of the invention, as shown in FIGS. 1 to 3,
comprises a cylindrical body provided in its central zone with a
housing 2 which is opened by its upper part. Said housing 2 is
limited by a lower base 3 and is surrounded by a perimeter wall
4.
[0032] The wall 4 is provided with windows 5 and ribs 6 which are
longitudinal to the axis of the piece 1. Located in the center of
the base 2, there is a cylinder 7 whose outer surface is provided
with a plurality of longitudinal ribs 8.
[0033] The function of the described elements will be explained
below.
[0034] The piece 1 shown in the figures is intended to be used as a
fixing element of an element, such as a pipe or a tube, to a wall.
Said piece 1 is fixed to the wall by means of a nail, thus, it is
necessary that said piece can be adapted to the use of nail
guns.
[0035] The nail guns comprise a cylindrical outlet mouth 9 from
where the nail is expelled. The piece 1 can be fitted to the outlet
mouth 9 of the gun to avoid that the user has to hold it while the
gun is actuated.
[0036] The attachment of the mouth 9 of the gun and the piece 1 of
the invention is carried out inserting the end of the mouth 9
inside the housing 2 (FIG. 4) my means of an axial movement, in
such a way that the base 3 of the piece 1 is placed in front of the
outlet orifice of the mouth 9 of the gun (FIGS. 5, 6 and 7).
[0037] The ribs situated in the wall 4 press against the outer
surface of the end of the mouth 9 of the gun, thus, the piece 1 is
properly fixed and centered by means of an easy movement.
[0038] As it can be seen, the cylinder 7 and the ribs in the center
of the base 3 of the piece are placed inside the mouth 9 of the
gun. Although in the represented embodiment the inner diameter of
the mouth is larger, the ribs 9 may do the same function than the
ribs 6 of the wall 4, pressing against the inner surface of the
mouth 9 for fixing the piece when the inner diameter of the mouth
is smaller.
[0039] With the piece attached to the mouth 9 of the gun, the user
can push both elements against the wall and shot the nail. Said
nail is expelled from the mouth of the gun, piercing the base 3 of
the piece 1 until it is driven into the wall, and it is placed
inside the cylinder, which also absorbs the impact, preventing the
nail from damaging the wall and its head from piercing the
piece.
[0040] Once the piece 1 has been fixed to the wall, it can be used
as a support for fixing elements such as strips or pieces that can
be coupled to the windows 5, which will hold the element to be
supported.
[0041] Although the ribs 6 represented in the described embodiment
are smooth, they also may consist of a row of small protrusions or
any other suitable shape for the intended use.
[0042] In FIG. 8 a new embodiment of the piece 1 of the invention
is shown. In this case, the piece has, like the previously
described piece, the longitudinal ribs 6 and the housing 2 for the
mouth 9 of the gun. The piece 1 of the embodiment also includes a
pair of flexible side arms 10 which allow fixing a pipe in an easy
way without having to use accessory elements.
[0043] Although two different means for fixing the piece 1 to an
object to be supported have been described, said means may also be
of the type and shape which can be adapted more suitably to
different shapes of said objects.
