DESCRIPTION

CUSHIONING DEVICE FOR CLOSING AND / OR OPENING FOR DOORS

SLIDING

Field of the invention

The present invention refers to a closing and / or opening damping device for sliding doors in general within the field of construction and / or building and, more especially, for those doors equipped with one or more sliding glass or sliding doors. wood that are suspended from an upper profile or guide rail that allows guiding the movement of said sliding leaves during the opening and closing of the door.

Background of the invention

Sliding doors of the type described are widely used in the field of construction and / or building to allow communication and / or separation between different rooms, rooms and / or spaces in general, as well as to allow opening and closing of various types of furniture, such as cabinets.

These types of doors have at least one manually operated sliding glass or wood sheet, which the user pulls to allow the door to open and / or close. On many occasions, especially in doors of considerable size, these leaves have a remarkable weight and / or considerable inertia, so if the user releases the leaf prematurely, it can continue to move by its own inertia and / or by the impulse exerted by the user, until it ends up impacting strongly against the door frame and / or the enclosures that delimit the door. These impacts can damage the door itself or other surrounding elements.

To avoid this problem, damping devices are usually used, which can be used to close and / or open the door, depending on its arrangement and mounting inside said door. In any case, these devices are usually arranged on the sliding sash integrally therewith, in order to move with it, and within the upper profile or guide rail, in order to interact with an external activator of a fixed character normally arranged in a end of said upper profile or guide rail, so that it can come into action shortly before the closing and / or opening of the door is completed. These devices in turn have a housing that has two guide grooves arranged laterally symmetrically; a cylinder-piston assembly, the piston of which has an actuation end; a spring having a movable end and a fixed end with respect to the casing; and a trigger attached to the movable end, configured to move along the guide grooves from a loading position to an unloading position by the action of the external actuator, interacting during its travel with the actuation end to damp said displacement. With this, the closing and / or opening of the door takes place in its final moment in a controlled, smooth and / or progressive way, cushioning and / or reducing the speed of the sliding leaf to avoid blows, in the event that it is move quickly due to its inertia. Also with this, the closing and / or opening of the door is carried out in a firm way so that once it reaches the final closing and / or opening position, it is not closed and / or loosened badly. An example of this type of damping device can be seen in Figures 1a, 1b and 1c.

In any case, in damping devices of the previous type, the trigger always finds the external actuator in the device's loading position, that is, when said trigger is separated from the cylinder-piston assembly, with the piston and spring extended. The contact between the trigger and the external trigger then produces a movement of the trigger that releases it from its position and, at the same time, allows the trigger to be hooked to the external trigger. The spring tension then pulls the sliding leaf, while the cylinder-piston assembly controls its speed at the final moment of closing and / or opening the door, without manual intervention by the user. All this occurs while the trigger moves from the loading position to the unloading position, due to the sliding of said trigger along the guide grooves. Once in the unloading position, the trigger is adjacent to the cylinder-piston assembly, with the piston and spring retracted. The trigger is therefore still hooked to the external activator, once the closing and / or opening of the door has been completed, without freedom of movement. It is the user himself who, by manually pulling the sliding leaf to start the door opening and / or closing process again, provides the necessary force to tension the spring and bring the trigger back to the loading position. When the trigger reaches that position of charge remains locked in it, allowing the release of the external trigger. The system is thus ready to repeat the previous process.

The correct operation of the damping devices of the previous type necessarily requires a prior conditioning of them before proceeding to their installation and / or assembly on site. Specifically, it requires a spring preload to leave the trigger in the loaded position, as well as to arrange the damping device on the correct side so that the external trigger finds the trigger frontally and not vice versa. Well, if the trigger is left in the unloading position, since it does not have freedom of movement in said unloading position, when the external trigger encounters the trigger, it impacts strongly against the latter. The trigger therefore opposes the advance of the external trigger, without letting it pass, so that said trigger cannot engage the trigger in order to bring it to the loading position.

The operators must therefore take care of preloading the spring and correctly positioning the damping device, together with the associated sliding leaf, with respect to the external actuator. This in itself already entails a series of drawbacks since, in addition to increasing installation time, a simple installation oversight, such as forgetting the spring preload, could render the damping device unusable, or inoperative, once Once the door has been assembled, it is necessary to disassemble the sliding leaf together with the device, and to assemble it again once the spring preload has been made.

But, even on properly fitted and functioning sliding doors, problems can occur after time that render the damping device unusable. This usually occurs when the trigger accidentally jumps out of its loading position due to vibrations and / or external shocks, so that, under tension by the spring, it moves directly to the unloading position without having the external trigger hooked. Being therefore out of service for the reasons set out above. In this case, moreover, the consequences may be worse. As these types of systems are often mounted on upper profiles or hidden guide rails in false ceilings, so that the damping device is usually not very accessible. Requiring therefore the intervention of the operators in assemblies and / or works already finished, to disassemble and assemble sliding door again.

The present invention solves the aforementioned problems by means of a damping device, the configuration of which allows the external trigger to be hooked to the trigger even when it is in the unloading position. This ensures the continuity of operation of the sliding door at all times, the reactivation of the system even in the event of an accidental discharge, in addition to facilitating the installation and / or assembly operations by not having to previously condition the device, also guaranteeing with this an efficient assembly and reducing the risk of errors.

Description of the invention

The present invention refers to a closing and / or opening damping device for sliding doors, comprising:

- a housing having two guide grooves arranged laterally symmetrically;

- a cylinder-piston assembly, the piston of which has an actuation end;

- a spring having a movable end and a fixed end with respect to the casing; and - a trigger attached to the movable end of the spring, configured to move along the guide grooves from a loading position to a discharge position by the action of an external trigger, interacting during its travel with the actuation end to damping said displacement;

where:

- in the loading position, the trigger is separated from the cylinder-piston assembly, with the piston and spring extended; and

- in the unloading position, the trigger is adjacent to the cylinder-piston assembly, with the piston and spring retracted or compressed.

Said damping device is characterized in that the trigger has, in the unloading position, a retractable movement configured to allow the engagement or re-engagement of the external trigger to the trigger.

In this way, in the event of a possible accidental discharge of the device or unexpected release of the trigger, the external trigger finds said trigger in the position of it discharges and gently contacts it, then producing a retractable movement of the trigger that displaces and / or collects it enough to allow the external trigger to pass. There is thus a slight contact with the front part of the trigger, but in no case an abrupt impact against it, nor an opposition to the advance of the external trigger, since the trigger has a certain freedom of movement in the unloading position.

In turn, said movement and / or retracted position of the trigger does not prevent it from re-engaging the external actuator by reversing the direction of movement of the sliding sheet, bringing it back to the loading position. Thus, the full operability and / or functioning of the damping device is restored in any situation, without the need to disassemble the door and / or have to access said device. Therefore, it is not necessary to perform a preload of the trigger to leave it in the loading position during the assembly of the door, since, once the installation has been carried out, the damping device can be enabled by a simple movement of the sliding leaf on the proper sense.

Preferably, the retractable movement allows the trigger to be tilted relative to the housing, and more specifically relative to the guide grooves, in the unloading position. So that said trigger is configured to tilt (turn, rotate, pivot ...) to collect, nestle and / or move as necessary to allow the external trigger to pass. Said rocking movement can also be accompanied by a slight sliding and / or linear movement of the trigger along the guide grooves while turning and / or rotating the trigger in the unloading position.

According to other particular cases of realization, the retractable movement can be produced by means of the flexible configuration of certain parts of the trigger that, when contacting the external activator, allow its passage. The tilt of the trigger and its partially flexible behavior can be used separately or in combination.

Preferably, the trigger is made of technical plastics.

Preferably, the trigger comprises two sliding pins that protrude laterally in a symmetrical way to be housed each one of them within the corresponding guide slot defining a pivot or rotation axis, where said sliding pins are configured to slide along of said guide grooves from the loading position to the unloading position.

Preferably, the trigger comprises at least one auxiliary pivot that projects laterally so as to be outside the guide slot. Said auxiliary pivot is configured to tilt or rotate around the tilt axis defined by the slide pivots. According to a preferred embodiment, there are two auxiliary pins arranged symmetrically on the trigger, aligned along an axis parallel to the pivot axis.

These auxiliary pivots have multiple functions. First, the arrangement of the auxiliary pins outside the guide grooves allows the trigger to pivot or swivel around the slide pins arranged within the guide grooves. Second, said auxiliary pins work in collaboration with the slide pins to assist in locking the trigger in the loading position, as well as to allow its subsequent unlocking. Then, they also serve to accompany and / or give greater stability to the movement and / or sliding of the trigger along the guide grooves, combining sliding pins that go inside the guide grooves with auxiliary pins that go outside of the same. And finally, they exercise an upper stop function to keep the trigger in the appropriate place in the unloading position, preventing it from tipping up or upward before being collected and / or protruding excessively at the top, thereby hindering the proper movement of the damping device or colliding with other elements. Optionally, said auxiliary pivots can also exercise a lower stop function, working with other elements of the housing to limit the retractable movement downwards or downwards.

Both the sliding pins and the auxiliary pins can be shaped by means of projecting elements and / or ends, preferably cylindrical and with a smooth surface to favor their sliding and rotation both inside and outside the grooves. of guidance. Preferably, the pins are formed of metallic materials.

Preferably, the trigger comprises:

- a first projection configured to receive the external trigger in the loading position;

- a second projection; and

- a housing defined between the first projection and the second projection, configured to engage the external trigger when passing from the loading position to the unloading position.

Under normal operating conditions, the first projection is configured to frontally contact the external trigger. Said contact tilts the trigger in the loading position, causing it to be unlocked. The tilting of the trigger causes at the same time an upward or upward movement of the second projection, sufficient to engage a projecting part of the external actuator between the housing defined between both projections. Once the trigger is released from the loading position, it is trapped in the external trigger, which is in a fixed position on the upper part of the door, either on the upper profile or guide rail, or on the wall itself. or ceiling. So the spring tension causes the sliding blade to move until the trigger reaches the unload position. The speed of said movement is damped and / or controlled by the cylinder-piston assembly, which at the same time guarantees that the sliding leaf remains firm and / or secure in any of the closing and / or opening positions, preventing it from being loose.

After accidental release of the trigger, a sudden movement of said trigger automatically occurs along the guide grooves, due to spring tension, until said trigger reaches the unloading position. Since the external trigger is in a fixed position, released from the trigger, the accidental movement of said trigger does not translate into any movement and / or damping of the sliding blade, which remains immobile during said accidental discharge. To reset the damping device so that it is operational again, the user must move the sliding sash towards the external trigger. In this case, it is the second projection that makes frontal contact with the trigger. external. The contact of the external trigger with said second projection causes the retractable movement of the trigger, so that the second projection in turn undergoes a slight downward or downward displacement, enough to allow the projecting part of the external trigger to pass over the second. projection. Once the protruding part of the activator is in the housing defined between both projections, the contact on the second projection disappears, thereby stopping the force that causes the retractable movement of the trigger in a downward direction. Since the trigger is still attached to the spring, which has moved slightly downward during the retractable movement of said trigger, it is the spring itself that, when returning to its rest position, pulls the trigger slightly to reverse the retractable movement, that is, to make it tilt in the opposite direction and regain the position it had before coming into contact with the external trigger. When the trigger recovers its position, it engages the external trigger between the two projections, so that the damping device becomes operational again.

Preferably, the first projection projects above the second projection, so that each of the projections frontally contacts the external activator in the corresponding way, depending on each of the above-mentioned situations.

Preferably, the trigger comprises an actuation wall configured to interact with the actuation end of the piston, wherein said actuation wall has a cam profile or curved profile. This type of profile facilitates the retractable movement of the trigger in the unloading position, allowing it to tilt and / or rotate appropriately. Specifically, said cam or curved profile prevents the trigger from abutting the upper part of the actuation end before completing the necessary turn to allow the external trigger to pass in a situation of accidental discharge. It also reduces the friction of the actuation wall with the actuation end of the piston during the swing of the trigger, so that there is a smooth sliding between the two and without blocking.

Preferably, the trigger comprises a gap or open space in a central part of the actuation wall, in order to further reduce friction with the actuation end of the piston, also favoring sliding between the actuation wall. actuation and actuation end during retractable movement of the trigger.

Preferably, the trigger comprises a hooking element configured to receive the movable end of the spring. Preferably, said hook has a central arrangement on the trigger to receive a single spring. This embodiment reduces the number of components of the damping device, resulting in a simpler and lower cost device. However, according to other particular embodiments, the trigger may comprise one or more hooking elements to hook more than one spring, for example, two or three springs arranged horizontally in parallel, etc.

Preferably, the trigger comprises an upper stop configured to limit retractable movement of the trigger in a downward direction by contacting said upper stop with the actuation end of the piston. This prevents the trigger from swinging down excessively and can infer with other elements arranged below and / or be blocked by them.

The housing of the damping device can adopt various structural and / or material configurations, preferably adopting a substantially narrow and elongated shape of rigid plastic material, with the appropriate dimensions to be housed within the guide rail or upper profile of the door, and to be able to move. inside it.

Preferably, the casing is formed by two lateral bodies, preferably symmetrical, and removable from each other, in order to facilitate the assembly and / or manufacture of the damping device, as well as access to its internal components for repair and / or maintenance issues.

Preferably, the housing comprises at least one recess arranged below the guide grooves, separated from the corresponding guide groove by a limit wall. This free space allows the accommodation and movement of the auxiliary pins outside the guide grooves. This in turn allows the trigger to tilt both in the loading position and in the unloading position.

Preferably, the boundary wall is configured to limit the retractable movement of the trigger in an upward or upward direction by contacting the auxiliary pivot against said boundary wall.

Preferably, each guide groove comprises:

- a curved section in the loading position; and

- a straight section that extends from the curved section to the unloading position.

The curved section in the loading position is the cause of the trigger being locked in that position, retaining the sliding pins despite the spring tension on the trigger.

The straight section is the one that allows a relative movement between the sliding pins and the guide grooves to bring the trigger from the loading position to the unloading position once unlocked by the external trigger.

Preferably, the damping device also comprises rolling means, preferably wheels and / or rollers, integrated in the housing configured to allow the device to move along a guide rail. This also makes it possible to reduce the number of components necessary for the correct operation of the door, while the resulting damping device is more compact and robust. Such rolling means can be arranged both in the front and / or rear of the damping device in the same or different number of elements (wheels, rollers ...).

Alternatively, the rolling means can be arranged outside the damping device, as a separate and independent element thereof duly linked to the sliding leaf, resulting in the system of the present invention being equally functional.

Preferably, the damping device comprises clamping means, preferably screws and / or bolts, integrated in the casing configured to allow the clamping of a sliding sash. This also makes it possible to reduce the number of components necessary for the correct operation of the door, while the Resulting damping device is more compact and robust. Such fastening means can be arranged both in the front and / or rear part of the damping device in the same or different number of elements (screws, bolts ...).

Alternatively, the fastening means can be arranged outside the damping device, as a separate and independent element thereof, duly linked to the sliding sash, resulting in the system of the present invention being equally functional.

Detailed description of the invention

Figures 1a and 1b respectively show an internal longitudinal view of a damping device (1 ') according to the state of the art in the loading position (P1) and in the unloading position (P2).

As can be seen, the damping device (1 ') has a casing (2') that has two guide grooves (3 ') arranged laterally symmetrically (although only one of them is illustrated in the image); a cylinder-piston assembly (4 '), whose piston (41') has an actuation end (42 '); a spring (5 ') having a movable end (51') and a fixed end (52 ') with respect to the casing (2'); and a trigger (6 ') attached to the movable end (51'), configured to move along the guide grooves (3 ') from a loading position (P1) to a discharge position (P2) by the action of the external actuator (A), interacting during its travel with the actuation end (42 ') to damp said displacement. The trigger (6 ') moves along the guide grooves (3') by means of sliding pins (61 '), all of them arranged inside said guide grooves (3').

The correct operation of this damping device (1 ') necessarily requires a preload of the spring (5') to leave the trigger (6 ') in the load position (P1), Figure 1a, as well as arranging the damping device (1 ') on the correct side during installation and / or mounting so that the external trigger (A) finds the trigger (6') from the front and not the other way around.

Figure 1c shows an internal longitudinal view of a damping device (1 ') according to the state of the art in the event of an accidental discharge.

As can be seen, the trigger (6 ') has accidentally jumped from its loading position (P1), so that, tensioned by the spring (5'), it has moved directly to the unloading position (P2) without being hooked. the external trigger (A). Since the trigger (6 ') does not have freedom of movement in said discharge position (P2), when the external trigger (A) encounters the trigger (6') it impacts strongly against the latter. This freedom of movement is mainly imposed by the series arrangement of the two sets of sliding pivots (61 ') inside the guide grooves (3'), which prevent their tilting in the unloading position (P2), as well as by the configuration of the trigger itself ( 6 ') causing it to be completely stuck and tight against the actuation end (42') of the piston (41 ') in said discharge position (P2). The trigger (6 ') therefore opposes the advance of the external trigger (A), without letting it pass, so that said external trigger (A) cannot engage the trigger (6') in order to bring it to the loading position (P1 ). The damping device (1 ') is thus inoperative.

Figure 2 shows a perspective view of the damping device (1) of the present invention, represented in this case in the discharge position (P2). According to the present example, the casing (2) is formed by two lateral bodies (2a, 2b), preferably symmetrical, and removable from each other, in order to facilitate the assembly of the damping device (1) and the access to its components. internal for repair and / or maintenance issues.

Figures 3a and 3b respectively show an interior longitudinal view of the closing and / or opening damping device (1) for sliding doors of the present invention in the loading position (P1) and in the unloading position (P2). It corresponds to the damping device of Figure 2, devoid of one of the lateral bodies (2a, 2b).

As can be seen, the damping device (1) comprises:

- a casing (2) having two guide grooves (3) arranged laterally symmetrically;

- a cylinder-piston assembly (4), the piston (41) of which has an actuating end (42);

- a spring (5) having a movable end (51) and a fixed end (52) with respect to the casing (2); and

- a trigger (6) attached to the movable end (51), configured to move along the guide grooves (3) from a loading position (P1) to an unloading position (P2) by the action of an activator external (A), interacting during its travel with the actuation end (41) to cushion said displacement; where:

- in the loading position (P1), the trigger (6) is separated from the cylinder-piston assembly (4), with the piston (41) and the spring (5) extended; and

- in the unloading position (P2), the trigger (6) is adjacent to the cylinder-piston assembly (4), with the piston (41) and spring (5) collected.

In Figures 3a-3c only one of the guide grooves (3) is shown, since only one of the lateral bodies (2a, 2b) of the damping device (1) is shown. The two guide grooves (3) can be seen in the cross section of Figure 5.

The casing (2) comprises at least one recess (7) arranged below the guide grooves (3), separated from the corresponding guide groove (3) by a limit wall (71).

Each guide groove (3) comprises:

- a curved section (31) in the loading position (P1); and

- a straight section (32) that extends from the curved section (31) to the discharge position (P2).

The curved section (31) in the loading position (P1) is the cause of the trigger (6) being locked in said position, despite the tension of the spring (5) on the trigger (6). The straight section (32) is the one that allows relative movement between the trigger (6) and the guide grooves (3) to bring the trigger (6) from the loading position (P1) to the unloading position (P2) once unlocked by external trigger (A).

As can be seen in Figure 3a, the trigger (6) finds the external actuator (A) in the load position (P1) of the damping device (1). The contact between the trigger (6) and the external trigger (A) then produces a movement of the trigger (6) that releases it from its position and, at the same time, allows said trigger (6) to be hooked to the external trigger (A). The tension of the spring (5) then pulls the sliding leaf (H), Figures 13 and 14, while the cylinder-piston assembly (4) controls its speed at the final moment of closing and / or opening the door (P), without manual intervention by the user. All this occurs while the trigger (6) moves from the loading position (P1) to the unloading position (P2), due to the sliding of said trigger (6) along the guide grooves (3).

As can be seen in Figure 3b, once in the unloading position (P2), the trigger (6) is adjacent to the cylinder-piston assembly (4), with the piston (41) and the spring (5) collected. The trigger (6) thus remains hooked to the external actuator (A), once the closing and / or opening of the door has been completed. It is the user himself who, by manually pulling the sliding leaf (H), Figures 13 and 14, to start the door opening and / or closing process (P) again, provides the necessary force to tension the spring ( 5) and bring the trigger (6) back to the loading position (P1), Figure 3a. When the trigger (6) reaches said loading position (P1) it remains locked in it, allowing the release of the external trigger (A). The system is thus ready to repeat the process of opening and / or closing the door (P).

Figure 3c shows an interior longitudinal view of the damping device (1) of the present invention in a situation of accidental discharge.

As can be seen, the trigger (6) has accidentally jumped from its loading position (P1), so that, tensioned by the spring (5), it has moved directly to the unloading position (P2) without having the activator hooked. external (A). In this case, however, the trigger (6) presents in the unloading position (P2) a retractable movement (M ^R ) configured to allow the reclosing of the external trigger (A) to the trigger (6).

Specifically, when the user moves the sliding sash (H), the external trigger (A) finds the trigger (6) in the discharge position (P2) and gently contacts it, then producing a retractable movement (M ^r ) of the trigger (6) that moves and / or retracts it enough to let the external trigger (A) pass. There is thus a slight contact with a front part of the trigger (6), but in no case an abrupt impact against it, nor an opposition to the advance of the external trigger (A), since the trigger (6) presents a certain freedom of movement. movement in the unloading position (P2). Once the external trigger (A) has passed, it is the spring (5) itself which, when returning to its rest position, pulls the trigger (6) slightly to reverse the retractable movement (M ^R ), that is, to make it tilt in opposite direction and / or upwards, in order to regain the position it had before coming into contact with the external trigger (A). When the trigger (6) recovers its position, it engages the external trigger (A) again and becomes as shown in Figure 3b, so that the damping device (1) is fully operational again.

Figures 4 and 5 respectively show a bottom view and a cross section of the damping device (1) of the present invention, also reflected in the discharge position (P2).

Figures 6-12 show various views of the trigger (6) of the damping device (1) of the present invention.

As can be seen, the trigger (6) comprises two sliding pins (61) that protrude laterally in a symmetrical way to be each one of them housed within the corresponding guide groove (3) defining a tilting axis (61b), Figure 5. Said sliding pins (61) are configured to slide along said guide grooves (3) from the loading position (P1) to the unloading position (P2).

The trigger (6) comprises two auxiliary pins (62) arranged symmetrically, aligned along an axis parallel to the pivot axis (61b), which protrude laterally to be out of the guide groove (3), Figure 5. Said Auxiliary pins (62) are configured to tilt along the tilt axis (61b) defined by the slide pins (61).

The auxiliary pivots (62) are housed outside the guide grooves (3), and with the possibility of movement, in the recess (7) of the casing (2). This allows the trigger (6) to tilt in the discharge position (P2), both in a downward direction (M ^rd ) and in an upward direction (M ^ra ). Likewise, the auxiliary pivots (62) are configured to contact the limit wall (71), in order to limit the retractable movement (M ^r ) of the trigger (6) in an upward direction (M ^ra ). Figures 3c, 4 and 5.

The trigger (6) comprises:

- a first projection (63) configured to receive the external activator (A) in the loading position (P1);

- a second projection (64); and

- a housing (65) defined between the first projection (63) and the second projection (64), configured to engage the external trigger (A) when moving from the loading position (P1) to the unloading position (P2).

Under normal operating conditions, the first projection (63) is configured to frontally contact the external actuator (A), Figure 3a. Said contact tilts the trigger (6) in the loading position (P1), causing it to be unlocked. The tilting of the trigger (6) causes at the same time an upward or upward movement of the second projection (64), sufficient to engage a projecting part of the external actuator (A) between the housing (65) defined between both projections (63, 64). Once the trigger (6) is released from the loading position (P1), it is trapped in the external trigger (A), which is in a fixed position on the upper part of the door, either in the upper profile or guide rail (C), or on the wall or ceiling itself. Thus, the tension of the spring (5) causes the sliding sheet (H) to move until the trigger (6) reaches the unloading position (P2), Figure 3b. The speed of said movement is damped and / or controlled by the cylinder-piston assembly (4), which at the same time guarantees that the sliding leaf (H) remains firm and / or secure in any of the closing and / or opening positions. , preventing it from being loose.

After an accidental discharge of the damping device (1), it is the second projection (64) that frontally contacts the external activator (A), Figure 3c. The contact of the external trigger (A) with said second projection (64) causes the retractable movement (M ^r ) of the trigger (6), so that the second projection (64), driven by the movement of the trigger (6), undergoes in turn, a slight downward or downward displacement, enough to allow the projecting part of the external activator (A) to pass over the second projection (64). Once the protruding part of the activator (A) is in the housing (65) defined between both projections (63, 64), the contact on the second projection (64) disappears, thereby stopping the retractable movement (M ^R ) of the trigger (6) downstream. Since the trigger (6) is still hooked to the spring (5), which has moved slightly downwards during the retractable movement (M ^R ) of said trigger (6), it is the spring (5) itself that when return to its rest position slightly pull the trigger (6) to reverse the retractable movement (M ^r ), that is, to make it tilt in the opposite direction and regain the position it had before coming into contact with the external trigger (A) . When the trigger (6) recovers its position, it engages the external actuator (A) between the two projections (63, 64), so that the damping device (1) becomes operational again, Figure 3b.

The first projection (63) protrudes above the second projection (64) by a certain distance (h), Figure 12, so that each of the projections (63, 64) comes in frontal contact with the external trigger (A) accordingly, depending on the situations listed above.

The second projection (64) can additionally have a flexible character to favor the passage of the external activator (A).

The trigger (6) comprises an actuation wall (66) configured to interact with the actuation end (42) of the piston (41), where said actuation wall (66) has a cam profile or curved profile.

The trigger (6) comprises an open space (69) in a central part of the actuation wall (66), in order to further reduce friction with the actuation end (42) of the piston (41).

The trigger (6) comprises a hooking element (67) configured to receive the movable end (51) of the spring (5). Said hook (67) has a central arrangement on the trigger (6) to receive a single spring (5).

The trigger (6) comprises an upper stop (68) configured to limit the retractable movement (M ^R ) of the trigger (6) in a downward direction (M ^RD ) by means of the contact of said upper stop (68) with the actuation end ( 42) from piston (41), Figure 3c.

Figures 13 and 14 show an example of application of the damping device (1) of the present invention in a sliding door (P), illustrating the sliding leaf (H) in open and closed position respectively. Said sliding leaf (H) allows to open and / or close a passage between two walls or partitions (T).

As can be seen, the sliding leaf (H) is suspended from two damping devices (1) according to the present invention, which also act as fastening elements for the door (P). The damping devices (1) are configured to move inside the upper profile or guide rail (C). To control the closing and / or opening of the door (P), two external activators (A) are arranged in a fixed position, also inside the upper profile or guide rail (C) and close to its ends, one for each damping device (1). Said external activators (A) are arranged so that they can interact with the damping device (1) corresponding to the closing or opening of the door (P). In this case, the damping device (1) on the left of Figure 13 is in charge of damping the movement of the sliding leaf (H) when closing the door (P), while the damping device (1) on the right The one in Figure 13 is in charge of damping the movement of the sliding leaf (H) when opening the door (P).

Figures 15 and 16 show the damping devices (1) of the application example of Figure 13 in the loading position (P1) and in the unloading position (P2) respectively.

As can be seen, the damping device (1) also comprises rolling means (8), preferably wheels and / or rollers, integrated in the casing (2) configured to allow the device (1) to move along a rail. guide (C). In this case, the rolling means (8) are arranged both at the front and at the rear of the damping device (1).

The damping device (1) also comprises fastening means (9) in the form of screws and / or bolts, integrated in the casing (2) configured to allow the fastening of the sliding leaf (H).
