    [0002] Pincer for tightening leveling pieces of cladding tiles.
    [0003]
    [0004] Technique sector.
    [0005]
    [0006] The invention relates to a clamp for tightening leveling pieces of covering tiles, known on the market and consisting of a push wedge and a leveling element in the form of a "T".
    [0007]
    [0008] This pliers is applicable in the construction sector, in particular in laying tile work on various surfaces; and it has some characteristics that make it easier to adjust the pliers, without using any tools, and to correctly tighten the leveling pieces, depending on the thickness of the tiles to be leveled.
    [0009]
    [0010] State of the prior art
    [0011]
    [0012] Patent EP2532806 (ES2598702T3) describes a device for leveling rigid cladding plates arranged on a surface to be clad, the device in question comprising a leveling element and a clamping wedge and a tool or manual pincer for its operation.
    [0013]
    [0014] The leveling element, with a T-section, comprises a flat base adapted to be supported on the surface to be coated, and a flat wing, attached perpendicularly to the base and provided in its lower part with a first opening in which the wedge and extreme recesses to weaken it against shear stresses.
    [0015]
    [0016] The clamping wedge comprises a lower seating face and an upper working face, adapted to transmit a pulling force towards the second element that tends to separate the leveling piece from the surface; said work face presenting grooves that define saw teeth, to block the movement of the wedge backwards with respect to the second element.
    [0017]
    [0018] The manual tool comprises: - a support provided at a first end with a handle of polymeric material and, at a second end of a graduated scale, to apply the appropriate effort depending on the height of the tiles or covering plates; - a support element, made of polymeric material, comprising a guide adapted to allow its movement along the support and legs separated by an opening that allows the wedge to pass through and which are adapted to provide a distance between the support and the lining plate and; - a pusher of polymeric material connected by means of a joint with the support and provided with a first gripping portion and a second pushing portion to push the wedge by pivoting the support through the joint, causing the efforts to separate the leveling piece and the surface to be coated.
    [0019]
    [0020] This clamp or tool, like other existing ones on the market, has fixing means for fixing the support stop in different positions along the support, consisting of a screw screwed into the support stop and which exerts a pressure against the guide.
    [0021]
    [0022] These fixing means have different drawbacks in use: difficulty of actuation when the operator is wearing protective gloves; need to use a tool to drive the screw, especially when the tile fixing paste is deposited on the thread, deterioration of the thread due to wear due to the frequent changes in position of the support stop; risk of undesired displacement of the support stop due to insufficient tightening of the fixing screw, and of sliding it along the guide bar of the support.
    [0023]
    [0024] Therefore, the technical problem that arises is the development of a pliers, of the type mentioned above, that satisfactorily solves the problems mentioned above and related to the fixing of the support stop with respect to the guide bar of the support.
    [0025]
    [0026] Explanation of the invention
    [0027]
    [0028] The clamp for tightening leveling pieces of cladding tiles object of the invention, is of the type mentioned above and described in the preamble of the first claim. This curling iron has some characteristics aimed at satisfactorily solving the problems set forth regarding the fixing of the support element in different positions, suitable for acting on the leveling pieces and for leveling tiles of different thicknesses.
    [0029]
    [0030] Specifically, this pliers comprises: - a first, straight arm that has a handle at one rear end and a guide bar at the front end for the movable mounting of a support stop for the leveling element; - a second arm, at an angle, which has a rear end provided with a handle and at a front end a contact surface with the push wedge; - an axis of rotation of the pincer arms and; - means for fixing the support stop in different positions along the guide bar of the first arm.
    [0031]
    [0032] In order to solve the aforementioned problems, and according to the invention: the support stop comprises: a passage of a height greater than the guide bar; an axis mounted in a longitudinal groove of the guide bar and which enables the longitudinal displacement of the support stop along the guide bar and its relative rotation between a fixing position and a longitudinal displacement position of the support stop with respect to to said guide bar; and a spring that acts against a surface of the guide bar and tends to keep the support stop in the fixing position with respect to the guide bar.
    [0033]
    [0034] The means for fixing the support stop in various positions, longitudinally spaced from the guide bar, consist of a straight ratchet comprising: a row of teeth defined along the guide bar, and a mounted stop or finger on the support stop and that: in the fixing position of the support stop it is housed between any two consecutive teeth of the guide bar, and in the longitudinal displacement position of the support stop it is arranged at a distance from the end of the teeth.
    [0035]
    [0036] The spring mounted on the support stop tends to cause the support stop to rotate towards a fixing position in which the stop or finger engages between the teeth of the guide bar, preventing said support stop from being move longitudinally with respect to the guide bar.
    [0037]
    [0038] To change the position of the support stop, simply turn it manually, overcoming the resistance of the spring, until the stop or finger is released from the teeth, reaching a displacement position in which the support stop can run along the guide bar to the desired position, depending on the thickness of the tiles to be leveled.
    [0039]
    [0040] Once this position is reached, it is enough to release the support stop so that the spring rotates it back to a fixing position and that the stop or finger engages between two consecutive teeth of the guide bar.
    [0041]
    [0042] With these characteristics the problems posed are satisfactorily solved, since: the change of position of the support stop does not require the actuation of any screw; it is very simple since it is enough to manually rotate the support stop until it is released from the teeth to move it along the guide bar; and the ratchet guarantees a secure fixing of the support stop in the chosen position and avoids undesired movements of it.
    [0043]
    [0044] These and other additional features of the invention, included in the appended claims, will be more easily understood in view of the exemplary embodiment shown in the figures described below.
    [0045]
    [0046] Brief description of the content of the drawings.
    [0047]
    [0048] To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, by way of illustration and not limitation, the following has been represented:
    [0049]
    [0050] - Figure 1 shows an elevation view of the pliers of the invention during the tightening of a push wedge and of a tile leveling element in opposite directions.
    [0051]
    [0052] - Figure 2 shows an elevation view of the pincer of the previous figure, in which the support stop has been shown in a fixing position and has been sectioned by a vertical plane to allow visualization of the fixing elements of the same regarding the guide bar.
    [0053]
    [0054] Figure 3 shows an elevation view of the pincer, in which the support stop is shown in a longitudinal displacement position with respect to the guide bar, released from the teeth of said guide bar.
    [0055] Detailed exposition of embodiments of the invention.
    [0056]
    [0057] Figure 1 shows the pliers for tightening leveling pieces of covering tiles, acting in opposite directions against a thrust wedge (C) that acts on the tiles to be leveled and against a leveling element (E) in "T" shape that is displaced upwards by the action of the inclined upper surface of the wedge, and which acts against the lower surface of the tiles by pressing them against the lower surface of the wedge, making them level.
    [0058]
    [0059] The pincer comprises: a first straight metal arm (1), which has a handle (10) at one rear end and a guide bar (11) at the front end for movable mounting of a support stop (3) of the element leveling (E); and a second metal arm (2), angled, which has a handle (20) at one rear end and a contact surface (21) with the thrust wedge (C) at one front end; said arms (1, 2) being related by a rotation axis (4).
    [0060]
    [0061] The support stop (3) comprises a passage (31) of a height greater than the guide bar (11) and an axis (32) mounted in a longitudinal groove (12) of the guide bar (11); said axis (32) enables the longitudinal displacement of the support stop (3) along the guide bar (11) and its relative rotation between: a fixing position shown in Figures 1 and 2, and a displacement position longitudinal of the support stop (3) with respect to said guide bar (11), represented in figure 3.
    [0062]
    [0063] Said support stop (3) has a spring (33) that acts against a surface of the guide bar (11) and tends to keep the support stop (3) in the fixing position with respect to the guide bar (11 ) represented in Figures 1 and 2.
    [0064]
    [0065] The means for fixing the support stop (3) in various positions longitudinally spaced from the guide bar (11) are constituted by a straight ratchet comprising: a row of teeth (13) defined along the guide bar (11), and a stop or finger (34) mounted on the support stop (3) and that: in the position of fixation of the support stop (3) is housed between any two consecutive teeth (13) of the bar- guide (11), and in the longitudinal displacement position of the support stop (3) it is arranged at a distance from the end of the teeth (13).
    [0066] As seen in the attached figures, the guide bar (11) has a first longitudinal edge (14) that forms the support surface of the spring (33) of the support stop (3), and a second longitudinal edge (15), parallel to the previous one, in which the row of teeth (13) of the ratchet is defined.
    [0067]
    [0068] In order to guarantee that in the fixing position the support stop (3) is unable to move with respect to the guide bar (11), the teeth (13) of the guide bar (11) are inclined towards the rear end of the first arm (1) of the pliers, carrying the corresponding handle (10), that is, in the opposite direction to that of the support stop (3) acting against the leveling element (E).
    [0069]
    [0070] The guide bar (11) comprises a graduated scale (16) indicating different fixing positions of the support stop (3) with respect to the row of teeth (13), for leveling tiles of different thicknesses.
    [0071]
    [0072] This pincer has a spring (5) that acts against the first arm (1) and the second arm (2) and tends to keep the pincer in the open position, the arms (1, 2) recovering their position when the pressure is released manual necessary for its operation.
    [0073]
    [0074] Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not entail an alteration of the essential features of the invention that are claimed below.
