Description

the sliding leaf the cable is extended tightening the spring, and once the sliding leaf is released the spring is loosen and pulls from the cable to drag it. The operation mode related to the stop of the sliding leaf does have considerable differences compared to the previous case. More specifically, this type of devices requires the use of external stops which are arranged on some fixed point of the door. Among the different possibilities there are highlighted the use of elements that act as stops or rack-sections arranged near the side where the door is closed. In the case of racks, they are generally configured to receive a toothed pulley arranged on the sliding leaf. Once the toothed pulley is engaged with the rack the movement of the sliding leaf slows down. This type of devices has problems similarto the preceding case. That is, there is no possibility of adjusting the closing speed, said closing does not occur at constant speed and also sudden acceleration and deceleration events occur that can deteriorate or break elements of the device or the door, or even cause accidents. Besides these problems, there are mounting difficulties produced by the fact that there is an external stop to attain a correct adjustment.

Description Object of the invention [0001] The present invention refers to a self-closing device for sliding doors, of the type comprising at least one sliding leaf which is hung from an upper profile and which is configured to displace in the direction thereof. Where said device enables the sliding leaf to close autonomously, at a constant speed adjusted at the users will. The closing movement is performed in a secure, efficient, smooth and stable manner, avoiding undesired noises and slum shuts. The device of the present invention has in turn a reduced and compact size that facilitates mounting and maintenance tasks. [0002] The present invention is especially suitable for its use in sliding doors which have sliding leaves manufactured using any type of material, such as glass, wood, plastic or combinations thereof, and admits a great variety of construction variants. Background of the invention [0003] The sliding doors that close autonomously are of great interest, especially in the domestic and commercial areas, for energy efficiency reasons. The use thereof in any type of air-conditioned enclosure or space enables, for example, to significantly reduce the energy consumption intended for the thermal adaptation thereof. [0004] Nowadays, there are known different types of devices, more or less complex, which enable to perform the autonomous closing of sliding doors in a more or less efficient manner. [0005] Among the most simple ones, we can highlight the devices using one or more coil springs arranged longitudinally in the direction of the upper profile, where one of the ends is extended pushed by a drag mechanism integral to the sliding leaf during the opening thereof. Once the sliding leaf is released, it is pushed in the closing direction by the spring, which tends to recover its resting state. Generally, these devices are combined with the use of a cylinder-piston that serves to damp the closing. This type of devices has several problems. The first one of them is that, once the spring is selected and the device is installed there is no possibility of adjusting the closing speed. The second problem is that the closing does not occur at constant speed, that is, the sliding leaf is initially accelerated and then slows down producing sudden movements which can produce clashes, dangerous situations and swinging movements which can produce vibrations. The third problem is that, with time the spring starts to lose elastic strength until being insufficient to produce the complete closing of the door. [0006] Among the most complex closing devices we can highlight those that use a cable featuring an end joined to the sliding leaf, while the other end is related to a spring. The operation mode related to the door closing is equivalent to the previous case, during the opening of [0007] JP2002004701A discloses an automatic closing device for sliding doors, enabling a door to be closed at a constantly fixed speed. The door is closed by the energy stored in advance in a spring joined to a first pulley, while a braking generator linked to a second pulley generates the output corresponding to the closing speed of the door as braking force. Both pulleys are connected by an auxiliary braking belt, which in turn is connected to a drive belt configured to transmit the braking force to the sliding leaf.

[0008] In order to solve the aforementioned problems, the self-closing device for sliding doors of the present invention has an efficient and secure design that allows the closing of the sliding leaf at an adjusted constant speed at the users will, while having a reduced and compact size which facilitates mounting and maintenance tasks.

Description of the invention [0009] The device of the present invention is especially designed for sliding doors comprising at least one sliding leaf which is hung from an upper profile and which is configured to displace in the direction thereof. In this sense, the construction variants accepted by this type of doors are very diverse, beyond the materials that form them and their arrangement with respect to the adjacent enclosures. To name a few examples, the device of the present invention can be applied in sliding doors with one or more sliding leaves that move simultaneously in the same direction or in opposite directions.

[0010] In order to solve the aforementioned problems, the device of the present invention comprises the features of claim 1. The connection of the closing and brake pulleys through the drive belt enables the closing movement of the sliding leaf at a constant speed, which can ured to control the level of friction between the brake shaft and the brake drum. This adjustment enables to adjust the closing speed of the sliding leaf. also be adjusted by the user, as it will be described below. Such adjustment is considered optimum, for example, when the sliding leaf completes the closing in an appropriate manner and stops without producing damages when there is an obstacle or a person interrupting its forward movement, later completing the closing once the obstacle is removed or the person moves away. [0011] The drive belt is preferably joined to a connection skid integral to a traction clamp that fastens the sliding leaf, where said traction clamp comprises rolling means configured to be displaced on a rolling rail arranged along the upper profile. Generally, the sliding leaf is also attached to a dragging clamp, which is not engaged to the drive belt, where said dragging clamp comprises rolling means configured to displace on the rolling rail. Preferably, the drive belt is vertically arranged on the upper profile, for space optimization reasons. However, if the mounting requires it, the drive belt, together with the rest of the device components, can also be arranged in horizontal position with respect to said upper profile. [0012] The closing pulley preferably comprises: • a closing body, joined to the first rotation axis by means of a first bearing, that has an inner housing configured to house the elastic means; and • a closing cap, joined to the first rotation axis through a second bearing, that has first fixing means to the closing body to contain the elastic means. [0013] The closing body of the closing pulley comprises a first toothed perimeter configured to engage with the drive belt. [0014] The closing pulley preferably additionally comprises a pair of washers arranged between the elastic means, within the inner housing, where said washers enable to contain the axial efforts caused by said elastic means when they operate. [0015] Preferably, the elastic means comprise a leaf spring featuring an inner end joined to a first rotation axis and an outer end joined to the closing body, where said leaf spring is compressed during the opening of the sliding leaf and decompressed during the closing thereof. The leaf spring is selected according to the weight of the doorsliding leaves, so that it has enough strength to push them at the desired speed. Likewise, the prestressing of the leaf spring is adjusted so that, once the sliding leaf is closed, it maintains a minimum amount of accumulated energy. Thus, the appropriate closing of the sliding leaf is guaranteed, preventing its stop before it is completely closed, and installation tasks are facilitated, since it is possible to correct mounting dimensional errors produced by the inaccurate positioning of the device elements. [0016] The stop body preferably comprises a second toothed perimeter configured to engage with the drive belt. [0017] The stopping means preferably comprise a friction adjuster coupled to the brake drum, which is config [0018] The device of the present invention can be complemented by two lateral protection elements. The first one of them consists of a damper protection element, while the second one consists of a retaining protection element.

[0019] The damper protection element is configured to soften the closing of the sliding leaf at the last part, that is, at the time when it completes the closing position. The damper protection element is fixed to the upper profile to softly stop the final advance of the traction clamp, contact which is attained through a rubber piece or a piece of any other elastic material.

[0020] The retaining protection element fulfils a double function: it softens the opening of the sliding leaf at the last part, that is, at the time when it completes the opening position, and retains the sliding leaf if it is desired to maintain the door completely open for an indefinite period of time. In order to fulfil the damping function, the retaining protection element is fixed to the upper profile to softly stop the final advance of the dragging clamp, contact which is attained through a rubber piece or a piece of any other elastic material. In order to fulfil this retention function, the retaining protection element comprises a hitch plate with a joint configured to receive and retain a hitch screw arranged in the dragging clamp.
