Description

Modular multipoint closure system for doors.

Field of the Invention

The present invention concerns a system of multipoint lock, or multipoint lock, for doors that have the property of adapting modularly to different facilities  Features and needs

The denomination "multipoint" refers to that the closure system simultaneously governs several points of closing conveniently distributed within the closing frame of the door.

Thus, the invention relates to a system of multipoint lock (hereinafter, multipoint lock) that it comprises a central lock equipped with the main mechanism of drive and at least one other auxiliary closing latch that can be one or more forwarding latches, or forwards, that are high from the same front of the door where the central lock is, and / or an upper latch, or high point, that is on the upper edge of the door, and / or a bottom latch, or low, which is in the lower edge of the door, whose forwarding and high and low points they are handled from the central lock through a means of vertically sliding transmission.

Prior art

Currently all multipoint locks known are constituted according to the traditional system consisting of the drive generated in the mechanism of the central lock is transmitted to the other closing points through sections of flat rods that link the central lock with the next higher and / or lower forwarding and, in turn, this upper and / or lower forwarding is linked to another next upper and / or lower forwarding, and / or with a high and / or low point, by other respective sections of rods; these rods They run along mechanized dribbles at the door.

This traditional construction system determines that each installation is different from another, since the length of the transmission rods depends absolutely on the interdistance of the closing points in each case. Consequently, the doors cannot be built at the factory definitively, but the final adjustment must be carried out on site because any small mismatch can cause the system as a whole not to work or not with the proper reliability and smoothness; Take into account in this regard the multiple interconnections of mechanisms in a system consisting of a central lock, an upper forwarding, a lower forwarding, a high point and a low point, which constitutes a very common configuration.

On the other hand, the existence of so many interconnections is a source of multiplication of gaps that go in detriment to smooth operation and reliability, and which, due to the existence of more friction, produces more wear that progressively expand these gaps and change the operating conditions in the negative direction.

Explanation of the invention and advantages

Faced with this state of affairs, the lock multipoint now proposed radically breaks with the system traditional constructive and advocates a constitution in which the vertically sliding transmission medium is located in the sine of the door behind the central lock and the Forwarding

The introduction in this field of this concept constructive assumes that now the sliding transmission medium the lock drive is independent of how many wherever and where the key forwards are located multipoint In other words, with the same and unique means of Sliding transmission can be operated all points of multipoint lock closure and these closing points can be placed in one or another position of the closing frame without this affects the installation of the system; all that is needed is that this transmission medium is mechanically connected with the mechanisms of the central lock and forwards and, in its case, incorporate latch end means for high points and under which they can be direct or also through a mechanism, of  The same way it is currently done. This constructive concept define a provision that could be called "tangential" or "in parallel" of the sliding transmission means with respect to the central lock and forwards, compared to the traditional concept mechanical connection "in series" with interleaving of elements  transmitters between every two successive closing points.

In the system advocated the same material medium Sliding transmission serves for multipoint locks that have the same type and number of closing points, although these closing points are not interdistanced to the same extent in installation case. But also this same means of transmission Slider serves for a multipoint lock that has different number of closing points and of different types.

Currently the coexistence of high point and point low in a multipoint lock is solved by generating two drives in the opposite direction in the central lock which are carried by two sliding transmission elements; or with one-way drive carried by a single element of transmission and placing a direction inverter at the low point or in the high point Well, these solutions are compatible with the system now advocated.

In accordance with all of the above, the lock advocated multipoint constitutes a simple and economical solution which is applicable for any specific composition of it eliminating traditional problems due to interdistance between the closing points, making installation simpler and the door can leave the factory fully equipped with the desired multipoint lock configuration, without requiring perform any subsequent adjustment.

In addition the advocated multipoint lock eliminates the multiple mechanical connections of the traditional system and, for both, slack and friction problems that are inherent and that have been commented previously. What is an operation  more smooth, reliable and stable throughout the life of the lock multipoint

These and other features of the invention are evidenced in the detailed description that follows.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution is illustrated in the attached drawings preference of a multipoint lock according to the applied invention in various variants. In general this multipoint lock comprises a central lock (1) equipped with the main mechanism of actuation and at least one other auxiliary closing latch that it can be one or more forwarding latches, or forwarding (2), which are at the top of the same front of the door (6) where the central lock (1), and / or an upper latch, or high point (3), which is on the upper edge of the door (6), and / or a latch bottom, or low point (4), which is on the bottom edge of the door (6), whose forwarding (2) and high (3) and low (4) points are managed from the central lock (1) through a means of vertically sliding transmission.

Within this general constitutive scope the recommended multipoint lock presents the particularity (figure 1) that it comprises a said transmission means vertically sliding (5) that is located inside the door (6) by behind the central lock (1) and forwards (2) and is mechanically connected with this central lock (1) and these forwarding (2); according to the invention, said transmission means vertically sliding (5) is located in a vertical hole (7) that is practiced in a wooden door (6) and that is communicated laterally with the boxes that house the lock central (1) and forwarding (2).

The mere visual observation of this constitution advocated evidence that the transmitting medium vertically Slider (5) is independent of how many the closing points are  and how they are willing to each other; just that this means of vertically sliding transmission (5) be connected to the mechanisms of the central lock (1), of the forwards (2) and, in their  case, with the high point (3) and the low point (4).

The advantageous qualities of this constitution are also evident and have already been explained extensively above: modularity that allows its application to any multipoint lock configuration; possibility that the door (6) can be manufactured against warehouse by not requiring subsequent adjustments on site ; elimination of multiple and chained mechanical interconnections and, therefore, of their clearances and friction wear; Smooth and reliable operation throughout the life of the multipoint lock.

According to a particular embodiment of the invention the vertically sliding transmission medium (5) is a bar single tubular (8) that is mechanically connected to the lock central (1) and, where appropriate, with all existing forwarding (2) above or below this central lock (1). In the same way, the vertically sliding transmission means (5) is consisting of an upper tubular bar (9) and a bar lower tubular (10), the upper tubular bar (9) is connected mechanically with the central lock (1) and, where appropriate, with the forwarding (2) existing above it, and the tubular bar bottom (10) is mechanically connected to the central lock (1) and, where appropriate, with existing forwarding (2) below she.

Choosing this way for the medium of Vertically scrollable transmission offers a triple advantage: it is a normalized and therefore cheap commercial form; it's great mechanical strength; and it is sliding smoothly and easily guiable against, for example, flat shapes such as plates. In the variants of execution represented in the figures the option single tubular bar (8) appears only in figure 1, where all types of closing points have been represented contemplated in multipoint locks; the single tubular bar (8) implies that the central lock (1) will produce a drive of one-way output, for example ascending, and that in the low point (4) the latch will not be attached to the end of the bar single tubular (8), as represented, but this end will be coupled to a reversing mechanism of the direction of operation which incorporates the corresponding latch itself. The others Execution variants depicted in Figures 2 through 6 are made with the option of upper tubular bar (9) and bar lower tubular (10), which implies that the central lock (1) produces a two-way output drive, ascending to the upper tubular bar (9) and downward for the tubular bar lower (10), so that for the low point (4) it can be used a direct acting latch attached to the end of the tubular lower (10).

According to the invention, the single tubular bar (8) and the upper (9) and lower (10) tubular bars are provided of a plurality of conveniently distributed places in your length for mechanical connection with the central lock (1) and, where appropriate, with forwarding (2); and in particular (figure 1) these connection places of the single tubular bar (8) and of the bars upper (9) and lower (10) tubular are holes (13) that are practiced in conjunction with spikes (14) that are cylindrical with conical tip and that are linked to the mechanism central lock actuator (1) and forwards (2).

For the best guidance of single tubular bars (8), upper (9) and lower (10), the invention provides that in said vertical drill (7) are inserted bushings (11) whose interior is slidably adjusted with respect to the transmission medium vertically sliding (5); This solution is designed (figure 2) particularly in the case of wooden doors (6), as illustrated Figure 2. Similarly, for the case of metal door (6) (figure 3) the option in which said means of vertically sliding transmission (5) is installed in conjunction with guide elements (12) arranged within a metal door (6).

Figures 2 to 6 illustrate some of the variants of execution within the scope of this invention. Figure 2 is a four-point multipoint lock, which are, three frontal points, central lock (1) and forwarding (2) upper and lower, plus a high point (3); in this figure 2 it details the incorporation of the high point (3) that is valid both for the single tubular bar (8) as for the upper tubular bar (9), and similarly is illustrative for a low point (4) as shown in figure 1; this figure 2 also details the mechanical connection by means of the pins (14) than with its tip Conical thickness of increasing thickness provides effective guidance with respect to the mounting in the holes (13) of the tubular bars single (8), upper (9) and lower (10). Figure 3 shows a multipoint lock with three frontal locking points: the central lock (1) and forwards (2), one above and one by under it. Figure 4 is a three-point multipoint lock closing points: two front, the central lock (1) and a forwarding (2) upper, and a high point (3); this version is the same of figure 2 suppressing the forwarding (2) below, but owing indicate that the lower tubular bar (10) is maintained providing for future extension of the multipoint lock to more points of close, for example, lower forwarding (2) and / or low point (4). The Figure 5 is a multipoint lock also with two points of frontal closure and a high point (3); but, unlike the previous version, now the forwarding (2) is below the central lock (1) instead of being above. Figure 6 is the central lock (1) and a high point (3).
