    [0001] Mechanism and procedure of actuation of the door closing latch by mechanical impulse.
    [0003] TECHNICAL SECTOR
    [0005] The invention is located within the technical sector of manual mechanical door locksmith systems, specifically in that of the accessories that coupled to the doors allow interaction with the devices that they have installed on the surface of their leaf using a pedal driven with the foot and that are not factory-incorporated in the doors, is a later addition to the closing system.
    [0007] STATE OF THE ART
    [0009] Mechanical systems with elements driven by the movement of a pedal are commonly used in many devices with the purpose of acting on some element thereof, for example to open and close multiple household utensils.
    [0010] Currently some models of devices are available on the market that are used to operate the door handles using a pedal, but I have not been able to find an accessory that specifically allows the sliding latches of the door closer to be operated with a pedal.
    [0012] TECHNICAL PROBLEM RAISED
    [0014] The current absence of a device capable of activating the door latches with a pedal could be solved if a mechanism was available that meets these conditions:
    [0015] - Efficient operation.
    [0016] - Reliability for frequent use.
    [0017] - Easy to install on the door.
    [0018] - Simplicity and comfort in its use.
    [0019] - Adaptable to most commercial latches.
    [0020] - To keep it attached to the door, it should not be necessary to make any alteration to its integrity: drills, adhesives, additional carpentry, etc.
    [0021] - The mechanism must be integrated into the door without appearing to be a later addition.
    [0022] - Production costs must be reduced.
    [0023] - Reusable for other doors, since the mechanism is not altered when installed. - The mechanism must allow both the opening and closing of the latches with the same movement on the pedal.
    [0024] - The door handle must not intervene in the mechanical system of the device to prevent it from being activated when the handle is manipulated from the outside of the door.
    [0025] The mechanism tries to find a solution to the following problem: how to activate the sliding latch of a door without having to do it manually or using an accessory that is also activated manually. The simplest answer to this question is to use your foot, which will act on a pedal to initiate a series of movements that end with an impulse that moves the latch pin to engage or remove it from the door strike.
    [0027] This mechanism is a complement to the device described in the patent with publication number ES2797554 (Mechanism for activating door opening handles, by means of pedal pressure), for several reasons:
    [0028] - It completes the door closing and opening procedure using exclusively a single pedal since the door handles can be operated and also, if installed, the sliding door latches.
    [0029] - In the design of this mechanism it is foreseen that, once it has acted on the sliding latch, the external push element must be allowed to continue advancing without obstacles to the door lock handle.
    [0030] - This mechanism combined with the one described in ES2797554 makes it possible for a door with a handle and latch installed (Figure 1) to be closed or opened, using a single movement on the same pedal.
    [0031] - The mechanism (2) must be coupled and fixed on the external surface of the cover panel (3) described in ES2797554.
    [0032] - The driving force that moves it is provided entirely by its firm connection to the thrust element (1) described in ES279755. The downward vertical thrust comes from the pressure made on the pedal (5) described in ES2797554, and the upward vertical thrust comes from the spring of the driving part described in ES2797554.
    [0034] The final result of all the actions of the mechanism consists in that the pin (4) of the latch (32) moves to be inserted or extracted from the strike (35) of the door.
    [0036] Mechanism components:
    [0038] Two rigid panels superimposed forming a compact block and, between them, a dynamic section responsible for the movement of the pieces. The functions of these components (Figure 3) are:
    [0040] - Support panel (8): fixed on a stable element of the door, it holds the whole set of mechanism parts firmly and provides a guide and sliding surface for the dynamic section.
    [0042] - Cover panel (37): covers the components that make up the mechanism and channels the sliding of the dynamic section as it is attached to the support panel, forming a closed enclosure.
    [0044] - Dynamic section: it is located between the two panels and contains the elements that will be moved to act on the latch.
    [0046] Detail of the elements that make up each component:
    [0048] - Support panel (8): it is fixed on a stable element (3) already present in the door by means of fixings (6) located at the vertices of this panel. It is located above the lock handle and does not reach the top of the lock. It is divided vertically into three areas:
    [0049] vertical, which form an enclosure.
    [0051] 2 . Crank area (10): it is the middle area, which contains a hole (12) at its upper end where the shaft of a crank will be inserted.
    [0053] 3 . Actuation area (11): is the lower area, delimited by two pairs of parallel and vertical slats (9) that do not reach the lower end of this panel.
    [0055] - Cover panel (37): it is screwed onto the support panel from threaded holes (36) and rests on the upper face of the slats (9), delimiting with them an enclosure whose thickness will be sufficient to contain the pieces inside of the dynamic section. The edge of the lower side of this panel reaches the lower end of the slats (9) of the drive area (11) of the support panel so as not to obstruct the dynamic section.
    [0056] - Dynamic section: made up of the set of elements that transmit the mechanical impulse to the door latch in an orderly manner. The mechanical systems that comprise it are the following: thrust receiver (17), scotch yoke guide (18), crank (15), thrust platforms (22), pressure plates (23), (39), articulated system (27), (28), (40), (41) and latch linker (31).
    [0058] 1. Thrust receiver (17): it is the element that connects the mechanism to an external device to receive the mechanical impulse in the form of a force in a vertical downward direction and, at other times, in an upward vertical direction.
    [0060] 2. Scottish yoke guide (18): it is a piece formed by an elongated arm (19) that runs through the driving area (7) channeled by the slats (9) and the crossbar (38). At its lower end, and symmetrical with respect to the axis of the arm, there is a rectangular enclosure (20) with an interior hollow (21) that will run from one side to the opposite side the piston of the crank (16), whose external face will not exceed the plane that forms the outer face of the rectangular enclosure.
    [0062] 3. Crank (15): located in the area of the crank (10) and made up of an arm that at one end has a rotary joint (14) that links it to a shaft (13) inserted in a hole (12) of the support panel and at the other end there is another rotary joint (14) that joins it to the piston of the crank (16) that runs through the interior hollow (21) of the rectangular enclosure (20) from its internal face and without exceeding the thickness of the same.
    [0064] 4. Push platforms (22): they are located on each of the opposite narrow sides of the rectangular enclosure (20) and have the function of transporting the force of the piston of the crank (16) to exert pressure on the suitable parts only during a certain tour of it. It is made up of these elements:
    [0065] 4.1 The base of the platform (50): it is a piece made up of these contiguous plates: a rectangular plate (51) whose upper face will be in the plane of the lower edge of the rectangular enclosure (20), a perpendicular plate (52) to the former on its inner side and with a height that allows a sliding plate (53) to fit into a groove (45) made in the surface of the inner face of the lower side (43) of the rectangular enclosure and extending in straight line from one side end of that enclosure to the other side end. The slide plate (53) will be attached to a spring (44) housed in the slot (45) and fixed at the other end of the slot. The purpose of this spring is that the base of the platform (50) can return to its starting point on the sides of the rectangular enclosure (20) when the thrust of the piston of the crank (16) on the base of the platform has ceased. (50) and therefore the force that made the spring extend in its groove ceases. 4.2 Pressure prism (57): it is the part that directly pushes the pressure plates (23), (39). It is attached by means of the fasteners (54) to the base of the platform (50) forming rectangular enclosure (20). It has a slit (56) that, starting from its inner face, runs through it towards its opposite face without actually going through it. This slit is partially closed on its upper face by a cover (58) to form a hollow that is open on its upper inner part.
    [0066] 4.3 The retractable pin (34): it is housed inside that hole and adjusts to its sides, it is made up of an elongated piece (48) with a height that allows a curvilinear projection (47) located in its upper part to be able to touching a curvilinear projection (59) located on the upper outer side of the rectangular enclosure (20). The length of this elongated piece (48) must allow it to penetrate through its oblique side (46) into the surface of the section of the rectangular enclosure (20) through which the piston of the crank (16) moves to slide on it and then leave it in place by virtue of its retractable movement. The opposite side of the elongated piece (48), which should not reach the cover (58), will be joined to a narrow piece (49) that can move linearly inside the gap of the slit (56) and that is fastened to the bottom of it by means of a spring (55).
    [0068] 5. Pressure blades (23), (39): slide over the two actuation areas (11), channeled by the slats (9) and the crossbar (38). They rest on separation blades (24) of shorter length than the pressure blades and which have the purpose of forming a hollow interior space where the rectangular enclosure (20) can move freely. The blades have in their lower part a hole (25) that will allow them to be attached to the connecting rods (27), (40) of the articulated system to give continuity to the impulse.
    [0070] 6. Articulated system: made up of connecting rods (27), (40) with circular perforations at both ends. They are connected at their upper end to the pressure plates (23), (39) through the hole (25) using a union cylinder (26). At their lower end, the connecting rods are connected with the articulation cylinder (29) to the articulation rods (28), (41), longer than the previous ones and also with perforations at the ends. The articulation rods (28), (41) are connected to each other at their lower ends using a connecting cylinder (30) passing through the bores.
    [0072] 7. Latch linker (31): it is the connector between the articulated system and the latch (32), its purpose is to hold the handle (33) of the pin (4) that has the latch (32) to move it, in one direction or another, towards the strike (35) of the door.
    [0074] Mechanism operation:
    [0076] - The mechanism (2) must be fixed on a stable surface that is already attached to the door leaf and located above the door handle.
    [0077] - The thrust receptor (17) must receive a driving force in a vertical downward direction from a mechanical device external to this mechanism.
    [0078] - The scotch yoke guide (18) will move in a vertical downward direction and, by its design, the crank piston (16) begins to make a linear movement on the rectangular enclosure (20) from its initial position at one end of the itself (Figure 4).
    [0079] - The piston of the crank (16), when it starts its journey from one end of the rectangular enclosure (20), is adjacent to the pressure prism (57) and they perform a joint movement because the prism has a retractable pin (34) installed that intervenes in the advance of the piston of the crank (16) and therefore the assembly will be dragged.
    [0080] - With the advance of the pressure prism (57) driven by the scotch yoke guide (18), two different movements are being carried out: a vertical downward movement and a horizontal linear movement.
    [0081] - The vertical downward movement implies that the pressure prism (57) is squeezing the pressure plate (39), forcing it to descend.
    [0082] - The horizontal linear movement of the pressure prism (57) ends when the curvilinear projection (47) touches the curvilinear projection (59) forcing the retractable pin (34) to move push platform (22) and make it return to its initial position. With this, it is achieved that the piston of the crank (16) can no longer interact with the pressure plates when it passes under them in its advance until a new movement in the opposite direction to the current one is started from the opposite end of the the rectangular enclosure (20).
    [0083] - The downward vertical movement of the pressure plate (39) means, as it is connected by the connecting cylinder (26) with the connecting rod (40), that it also moves and that it continues with the impulse because it is joined at one end by means of the articulation cylinder (29) to the articulation rod (41) which, by being able to rotate at one end on the previous connecting rod, can modify the angle of application of the received force and make it so that at the end where it joins by means of the latch linker (31) to the handle (33) of the bolt (4), which can only move linearly, a movement is generated in the bolt (4) of the bolt (32) that moves it in a direction towards the strike ( 35).
    [0084] - The interconnection of the articulation rods (28), (41) by means of the latch linker (31) implies that the movement of one of them influences the other, if the articulation rod (41) then lowers the articulation rod (28) rises and drags with it the connecting rod (27) which in turn raises the pressure plate (23). The status of the parts is as shown in Figure 5.
    [0085] - The crank piston (16), once the pin (4) has moved, will no longer be able to act on any other element in the movement area (42) until, once the other end of the rectangular enclosure ( 20), start a new tour in the reverse direction. - When the scotch yoke guide (18) is at the point of maximum vertical descent then the piston of the crank (16) is at the midpoint of the rectangular enclosure (20) and the external driving force in a vertical downward direction will have ceased and an upward vertical external driving force is needed to move the scotch yoke guide (18) in the opposite direction to move the crank piston (16) from the midpoint to the other end of the rectangular enclosure (20 ) ..
    [0086] - Once this end has been reached, the piston of the crank (16) will have passed through the retractable pin (34) of the push platform (22) corresponding to that side and will be linked to it (Figure 6).
    [0087] - Due to the symmetry between the parts on the two sides of the mechanism, the sequence of actions that will take place in the operation of the mechanism from that end of the rectangular enclosure (20) will be similar to those described for the other end, but with the result end that the latch pin (4) will move in a direction opposite to the previous one.

The slide plate (53) will be attached to a spring (44) housed in the slot (45) and fixed at the other end of the slot. The purpose of this spring is that the base of the platform (50) can return to its starting point on the sides of the rectangular enclosure (20) when the thrust of the piston of the crank (16) on the base of the platform has ceased. (50) and therefore the force that made the spring extend in its groove ceases. - Pressure prism (57): it is the piece that directly pushes the pressure plates (23), (39).

    [7]
    7. Mechanism and procedure for activating the door closing latch by mechanical impulse according to claims 1 to 5 characterized by having a procedure for operating the mechanism that consists of:
    - The thrust receptor (17) must receive a driving force in a vertical downward direction from a mechanical device external to this mechanism.
    - The scotch yoke guide (18) will move in a downward vertical direction and, by its design, the crank piston (16) begins to make a linear movement on the rectangular enclosure (20) from its initial position at one end of the same.
    - The piston of the crank (16), when it starts its journey from one end of the rectangular enclosure (20), is adjacent to the pressure prism (57) and they perform a joint movement because the prism has a retractable pin (34) installed that intervenes in the advance of the piston of the crank (16) and therefore the assembly will be dragged.
    - With the advance of the pressure prism (57) driven by the scotch yoke guide (18), two different movements are being carried out: a vertical downward movement and a horizontal linear movement.
    - The vertical downward movement implies that the pressure prism (57) is squeezing the pressure plate (39), forcing it to descend.
    - The horizontal linear movement of the pressure prism (57) ends when the curvilinear projection (47) touches the curvilinear projection (59), forcing the retractable pin (34) to move towards the bottom of the slit (56) and giving the opportunity to spring (44) to act on the push platform (22) and make it return to its initial position. With this, it is achieved that the piston of the crank (16) can no longer interact with the pressure plates when it passes under them in its advance until a new movement in the opposite direction to the current one from the opposite end of the the rectangular enclosure (20).
    - The downward vertical movement of the pressure plate (39) means, as it is connected by the connecting cylinder (26) with the connecting rod (40), that it also moves and that it continues with the impulse because it is joined at one end by means of the articulation cylinder (29) to the articulation rod (41) which, by being able to rotate at one end on the previous connecting rod, can modify the angle of application of the received force and make it so that at the end where it joins By means of the latch linker (31) to the knob (33) of the bolt (4), which can only move linearly, a movement is generated in the bolt (4) of the bolt (32) that moves it in a direction towards the strike ( 35).
    - The interconnection of the articulation rods (28), (41) by means of the latch linker (31) implies that the movement of one of them influences the other, if the articulation rod (41) then lowers the articulation rod (28) rises and drags with it the connecting rod (27) which in turn raises the pressure plate (23).
    - The crank piston (16), once the pin (4) has moved, will no longer be able to act on any other element in the movement area (42) until, once the other end of the rectangular enclosure ( 20), start a new tour in the reverse direction. - When the scotch yoke guide (18) is at the point of maximum vertical descent then the piston of the crank (16) is at the midpoint of the rectangular enclosure (20) and the external driving force in a vertical downward direction will have ceased and an external upward vertical driving force is needed to move the crank (16) from the midpoint to the other end of the rectangular enclosure (20).
    - Once this end has been reached, the piston of the crank (16) will have passed through the retractable pin (34) of the push platform (22) corresponding to that side and will be linked to it.
    - Due to the symmetry between the parts on the two sides of the mechanism, the sequence of actions that will take place in the operation of the mechanism from that end of the rectangular enclosure (20) will be similar to those described for the other end, but with the result end that the latch pin (4) will move in a direction opposite to the previous one.
