Description

Technical Field

[0001] The invention relates to a striker for a lock.

[0002] In more detail, the striker according to the invention belongs to the technical field of the production and sale of strikers, in particular magnetic type strikers, for locks intended to close fixed furniture, such as doors and windows, made of various materials, such as aluminum, aluminum wood, wood and polyvinyl chloride.

[0003] The impactor according to the invention is particularly advantageous when mounted on a frame profile of the hollow type, such as a frame made of an aluminium alloy. Background Art

[0004] The use of strikers is known in the technical field of reference of locks for fixed furniture intended to be closed and / or opened, in particular doors and windows, installed in many types of buildings, such as offices, hotels, commercial shops, houses, apartments, etc.

[0005] A striker of known type for locks generally comprises a body insertable into a housing seat previously obtained on a fixed piece of furniture, in particular on a frame profile of a door or a window.

[0006] The body generally comprises a plurality of openings, in particular holes, suitable for receiving fixing means, in particular threaded fixing means, such as screws or the like, for fixing the striker to the profile of the frame.

[0007] The body also comprises a plurality of compartments adapted to receive opening / closing members, in particular members known in the technical jargon of the field as latches (e.g. of the magnetic or mechanical type), and slides movable by the aforementioned fixing means to fix the striker in the seat of the frame.

[0008] It is apparent that strikers for locks such as that briefly described above have proven to be deficient in practice.

[0009] The main drawback is that strikers for locks of known type are difficult to assemble and disassemble from the seat of the frame of a door or window, for example in order to carry out maintenance and / or adjustment and / or inspection operations on the door or window itself. In fact, during the aforementioned operations, especially if carried out by non-professionals, there is a risk that such fixings and the mobile slide will fall inside the hollow profile of the frame without being able to be recovered.

[0010] A further disadvantage is that the strikers of known type for locks are aesthetically unpleasing. In fact, the fixing means (i.e. screws etc.) of such strikers are visible to the operator, in particular such fixing means being arranged at the front face of the striker itself during use. This makes the whole of the door or window unpleasing. The strikers of known type therefore require a covering element intended to cover the above-mentioned fixing means. This leads to an increase in the number of parts required to complete the striker and therefore a greater complexity of construction and logistics. Summary of the invention

[0011] The technical task of the present invention is to propose a striker for a lock which allows at least partially overcoming the above-mentioned disadvantages of the prior art.

[0012] In particular, the object of the present invention is to provide a striker for locks, the assembly and disassembly of which on a frame profile of a door or window is simple and reliable even for non-specialized operators.

[0013] Another object of the present invention is to provide a striker for a lock, particularly suitable for a frame having a hollow profile, such as an aluminum alloy frame.

[0014] Another object of the invention is to propose a striker for a lock that allows a reliable mounting while allowing an aesthetic effect to be achieved.

[0015] According to the invention, all objects, individually or in any combination, as well as other objects resulting from the following description, are achieved by a striker for a lock having the features of claim 1 .

[0016] The dependent claims outline advantageous embodiments of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] With reference to the accompanying drawings, they are only used to illustrate embodiments of the present invention, with the purpose of better explaining the inventive principles on which the present invention is based in conjunction with the description. DETAILED DESCRIPTION

[0023] Referring to the drawings, a striker for a lock is generally indicated by numeral 10 .

[0024] The striker 10 according to the invention is found in particular in the technical field of manufacturing and selling locks, in particular magnetic locks, intended to be installed in profiles of frames of doors or windows, in particular hollow profiles inside. More specifically, such profiles are in particular made of aluminium alloys, for example by means of extrusion or drawing processes or the like.

[0025] However, the striker according to the invention can also be used on profiles made of wood or polyvinyl chloride without exceeding the protection range.

[0026] according to Figure 1 In the embodiment shown in FIG. 1 , the striker 10 for a lock includes a receiving body 20 .

[0027] In particular, the receiving body 20 extends between a first end 21 a and a second end 21 b along a longitudinal extension direction.

[0028] According to one aspect of the invention, the receiving body 20 has a cavity 20 ″ formed on the front face 20 a suitable for receiving a closing member, generally referred to as a “latch” in technical terms in the art, and preferably of the magnetic type (not shown in the drawings) along the insertion direction Z. The receiving body 20 also has a lateral surface 20 b.

[0029] like Figure 1 As shown, the cavity 20" is defined by two lateral walls and two head walls, the lateral walls are arranged to face each other and extend substantially parallel to the extension direction of the body 20, and the head walls face each other and extend substantially orthogonal to the two lateral walls. In particular, the two lateral walls and the two head walls are connected to each other.

[0030] The cavity 20" is also defined by a bottom wall 29a (to be presented and described in detail below) which is mechanically connected to the two lateral walls and the two head walls.

[0031] The impactor 10 also comprises a retaining element 30 positioned in the seat 22 of the receiving body 20 .

[0032] According to an aspect of the present invention, the seat 22 is preferably at the first end 20 a or the second end 20 b of the receiving body 20 .

[0033] According to one aspect of the present invention, the seat 22 has a substantially partitioned shape, that is, a substantially partially closed shape. Figure 4 As shown in , the seat 22 substantially defines a guide corridor which at least partially defines the direction along which the retaining element 30 can be moved.

[0034] like Figure 4 As shown in the figure, the retaining element 30 can be moved between a withdrawn position corresponding to an engagement configuration, in which the impactor 10 is fixed in a seat of a frame (not shown in the figures), and a retracted position corresponding to a release configuration, in which the impactor 10 can be withdrawn from the seat itself.

[0035] According to one aspect of the present invention, the retaining element 30 includes at least one sliding member, which is slidably arranged in the seat 22 of the receiving body 20 and can be moved between the engagement structure and the release structure along the movement direction Y, and the movement direction Y is transverse to, preferably orthogonal to, the insertion direction Z.

[0036] As shown in the figures, the receiving body 20 extends along a longitudinal extension direction which is substantially parallel to the movement direction Y.

[0037] Furthermore, according to the embodiment shown in the figures, the cavity 20 ″ of the receiving body 20 and the seat 22 are arranged substantially aligned with each other, in particular they are intercepted in the movement direction Y at respective center lines.

[0038] According to a preferred embodiment shown in the drawings, the retaining element 30 preferably comprises two slides, in particular a first slide and a second slide.

[0039] According to one aspect of the invention, the first slide is preferably substantially identical to the second slide. Advantageously, the first slide and the second slide are interchangeable in the respective positions 22 .

[0040] In more detail, each slide is slidably arranged in a corresponding seat 22 obtained in the receiving body 20 and can be moved between an engagement configuration and a release configuration in a corresponding movement direction Y, which is transverse to, preferably orthogonal to, the insertion direction Z. In particular, the slides are arranged on opposite sides of the receiving body 20 relative to the cavity 20 ″.

[0041] That is, the first slide may be inserted into the seat 22 provided at the first end 21 a , and the second slide may be inserted into the seat 22 opposite to the previous seat and provided at the second end 20 b .

[0042] According to the embodiment particularly shown in the figures, the impactor 10 comprises an adjustment member 50 which can be inserted into the receiving body 20 and which is optionally associated with the retaining element 30. In particular, the adjustment member 50 is configured to be actuated from the inside of the cavity 20" in a direction transverse to the insertion direction Z, so that the retaining element 30 is activated in a direction of movement Y transverse to the insertion direction Z.

[0043] Thus, the striker 10 has no visible adjustment member. Advantageously, the front face 20a thus has no discontinuities and is substantially planar in its extension. That is, such a front face 20a has no machined parts, such as holes, seats, cavities, etc., intended to receive fixing elements such as screws, etc. This allows obtaining an aesthetic striker 10 for a lock.

[0044] According to one aspect of the present invention, the impactor 10 for a lock further includes an arresting device 21, 31, which is inserted between the retaining element 30 and the receiving body 20 to limit the movement of the retaining element 30 along a predetermined stroke to avoid the retaining element 30 being detached from the receiving body 20 when the retaining element 30 switches between the retracted position and the withdrawn position.

[0045] That is, the arresting devices 21 and 31 essentially define limit stop barriers to prevent movement beyond the limits defined by the barrier of the retaining element 30 itself.

[0046] Advantageously, during the assembly or disassembly operations of the striker in the seat, the retaining element 30 remains engaged with the receiving body 20. Thus, the risk of the retaining element 30 being disengaged from the receiving body 20 and the element 30 itself falling, for example inside the seat of the hollow profile of the frame, is avoided.

[0047] According to one aspect of the invention, the arresting means 21 and 31 are obtained directly on the receiving body 20 and the retaining element 30, respectively.

[0048] That is to say, the arresting means 21 , 31 are obtained in a single part on the receiving body 20 and the retaining element 30 , respectively.

[0049] Advantageously, the impactor 10 is simple and inexpensive since it does not require any additional fixing means such as screws, rivets or the like to fix the above-mentioned arresting devices 21 and 31 to the body 20 and the retaining element 30, respectively.

[0050] In more detail, the arresting means 21 , 31 comprise an abutment element associated with the retaining element 30 , and a corresponding stop member integral with the seat 22 of the receiving body 20 , thereby defining a limit stop configured to abut against the abutment element.

[0051] In more detail, the abutment element is preferably toothed, in particular it has an arcuate portion R and a first planar operating surface, the arcuate portion R is preferably connected, facing outward from the cavity 20" of the main body 20, and the first planar operating surface is opposite to the arcuate portion R.

[0052] Instead, the stop member is barrier-shaped, in particular it has a second planar operating surface, which is substantially parallel to the corresponding first planar operating surface of the abutment element, and an inclined surface, which is opposite to the second planar operating surface.

[0053] like Figure 2 As shown in detail in FIG. 1 , the arresting devices 21 and 31 are configured to abut by means of contact between the first operating surface and the second operating surface. In particular, this contact is of the interference type.

[0054] Advantageously, the arcuate portion R and the inclined surface allow a simple and rapid snap-fitting movement of the retaining element 30 into the corresponding seat 22 (as described in detail below).

[0055] According to one aspect of the invention, in particular to achieve the above-mentioned snap-fitting movement, at least one of the abutment element and the stop member is made of a deformable material to enable the retaining element 30 to snap-fit ​​into the seat 22 of the receiving body 20 .

[0056] According to one aspect of the invention, the adjustment member 50 is actuatable, preferably by means of a spanner, in order to move the retaining element 30 in a movement direction Y transverse to the insertion direction Z.

[0057] According to one aspect of the invention, the adjustment member 50 and the retaining element 30 define a preferably threaded coupling of the screw-nut type.

[0058] In particular, the adjustment member 50 comprises a screw of the hexagon socket countersunk type, and the retaining element 30 has a threaded hole, preferably a through hole, configured to mechanically couple with the screw.

[0059] Preferably, the adjustment member 50 has a nominal thread size selectable between M3 and M5, preferably M4.

[0060] The receiving body 20 comprises a first sliding guide portion 25 obtained on the lateral surface 20 b and configured to receive the adjusting member 50 (ie, a hexagon socket countersunk screw).

[0061] according to Figure 4 In the embodiment of the invention shown in detail in FIG. 2 , the receiving body 20 comprises a second sliding guide portion 25 obtained on the lateral surface 20 b and configured to receive the second adjusting member 50 .

[0062] Preferably, the first sliding guide portion 25 and the second sliding guide portion 25 are substantially equal to each other.

[0063] More specifically, the first sliding guide portion 25 and the second sliding guide portion 25 are obtained on the same surface of the lateral surface 20 b of the receiving body 20 .

[0064] Thus, the insertion of the adjustment member 50 into the first and second sliding guides 25 can take place on the same side of the lateral surface 20 b. This is particularly advantageous in the case of the assembly of the impactor 10 by means of an automated system, such as an anthropomorphic robot, because the impactor 10, once oriented according to the faces obtained on the first and second sliding guides 25, does not need to be moved, in particular rotated substantially 180°, in order to insert the adjustment member 50 into the corresponding sliding guide 25.

[0065] Furthermore, each sliding guide 25 is preferably shaped to allow for customized insertion of the adjustment member 50 .

[0066] That is to say, Figure 2 and Figure 4 As shown in FIG. 1 , the shape of the first sliding guide portion 25 and the second sliding guide portion 25 substantially replicates the shape of the longitudinal cross section of the regulating member.

[0067] Advantageously, the adjustment member 50 remains housed in the first and second sliding guides without risk of traveling out of the way.

[0068] According to an aspect of the invention, the first sliding guide portion 25 and the second sliding guide portion 25 extend along respective housing directions S, which are substantially orthogonal to the movement direction Y and the insertion direction Z of the adjustment member 50 .

[0069] According to an aspect of the invention, the receiving body 20 has a through opening 28 facing inwardly towards the cavity 20 ″ of the closing member.

[0070] In particular, the opening 28 is configured to place the cavity 20 ″ in communication with the seat 22 , thereby enabling access (eg, by means of the aforementioned wrench) to the first adjustment member 50 .

[0071] According to the embodiment shown in the drawings, the receiving body 20 has two openings 28, which are preferably substantially equal to each other and arranged face to face with each other, in particular, one opening 28 is arranged at the first end 20a of the receiving body 20, and the second opening 28 is arranged at the second end 20b of the receiving body 20.

[0072] According to an aspect of the invention, the two openings 28 are preferably holes.

[0073] According to the embodiment shown in the drawings, the receiving body 20 comprises a compartment 29 suitable for receiving a magnetic closing element, said compartment 29 being adjacent to the cavity 20 ″ and separated therefrom by a bottom wall 29 a.

[0074] According to an aspect of the invention, the retaining element 30 and / or the receiving body 20 are made of a polymeric material, or preferably a fiber-reinforced polymeric material.

[0075] Otherwise, the receiving body 20 and / or the retaining element 30 may preferably be made of a metallic material, such as steel or an aluminum alloy.

[0076] According to an aspect of the invention, the seat 22 is obtained on the lateral surface 20b and is positioned below the edge of the front face 20a.

[0077] Advantageously, as mentioned above, the front face 20 a is substantially free of discontinuities such as holes, openings, recesses, etc. This allows to give an aesthetic effect to the front face 20 a and therefore to the receiving body 20 of the striker 10 .

[0078] According to a further aspect of the invention, the retaining element 30 has an activation saw-tooth shaped portion 30a for engaging with a seat of the frame.

[0079] Advantageously, such a sawtooth shape allows a better grip to be achieved between the retaining element 30 and the corresponding surface of the seat of the frame.

[0080] according to Figure 1-4 In the embodiment shown in FIG. 1 , the operation of the present invention is as follows.

[0081] Figure 4 An exploded view of the striker 10 for a lock is shown, in particular an operator taking the adjustment member 50 and inserting it along the sliding guide 25 in order to arrange it inside the receiving body 20 , substantially aligned along the movement direction Y.

[0082] The operator then takes the retaining element 30 and manually turns it a stroke so that it can clamp with the adjusting member 50. The operator then takes a wrench, in particular a male key, and uses it to rotate the adjusting member 50 so as to move the retaining element 30 along the threaded rod of the adjusting member 50, i.e. along the movement direction Y. During this movement, the snap-fitting of the retaining element 30 in the seat 22 occurs when the arresting means 21 and 31 come into contact with each other, in particular between the curved portion R of the abutment element and the inclined surface of the stop member.

[0083] This snap-fitting is facilitated by the fact that at least one of the retaining element 30 and / or the receiving body 20 is made of a deformable material, in particular an elastic material as described above.

[0084] Once inserted into the seat 22 , the retaining element 30 continues its movement in the movement direction Y until it has travelled the entire extension of the threaded rod of the adjustment member 50 and is substantially in contact with the bottom wall of the groove 22 .

[0085] In the above configuration, the impactor 10 can be inserted into the seat of the frame and fixed therein by reversing the rotation direction of the adjustment member 50, thereby moving the retaining element 30 outward, i.e. away from the cavity 20", and engaging the surface 30a against the corresponding surface of the seat of the frame.

[0086] In particular, during the above-mentioned movement, the retaining element 30 cannot travel beyond the stroke defined by the contact between the first planar operating surface and the second planar operating surface. In fact, such surfaces define a planar contact, in particular substantially orthogonal to the movement direction Y. This prevents the retaining element 30 from being decoupled from the adjustment member and, therefore, from being deattached itself from the seat 22 of the receiving body 20 .

[0087] Another object of the invention is a method for fixing an impactor 10 of the above-described type in a seat of a frame, the reference numerals of which will be retained for the sake of simplicity of description.

[0088] The method comprises the following steps:

[0089] - a profile providing a frame for a door or window; preferably hollow inside and preferably made of an aluminium alloy,

[0090] - forming a housing seat in the profile;

[0091] - accommodating in the housing seat a striker 10 for a lock according to one or more of the claims;

[0092] - Activating the adjustment member 50 to move the retaining element 30 between a retracted position corresponding to the release configuration and an extracted position corresponding to the engagement configuration.
