FIG. 03/8 “CONSTRUCTIVE ARRANGEMENT TOGETHER

BUFFER AND DRIVER FOR FURNITURE ”

Subject matter:

[001] This Utility Model Patent refers to a set of shock absorber and driver used in sliding doors for cabinets with support at the base. The screen damper adds value to the furniture as it provides a smooth, comfortable and safe closure for the doors due to the fine adjustment in the tension adjustment in the spring according to each particular door. In addition, it is constructively injected into a single housing, which facilitates its manufacture and installation, and functionally has a graduated actuator that only with its fixation system guarantees a perfect alignment, regardless of the thickness of the door. Through its innovations and differentials, the set becomes efficient, practical and quiet, with a pre-activation trigger, auto activation and assembly.

State of the art:

[002] Dampers used superiorly in sliding doors are known in the art, whose damping occurs with the closing movement of the internal telescopic piston, which require the joint installation of a driver and a guide with casters, in order to allow the movement the door. The damper is installed at the upper end of the door, and the guide with casters and driver, also called fisherman, are installed in line with the damper, close to the center of the door.

[003] This factor means that a set of two dampers, one for each side, cannot be installed on small doors since the guides with casters and actuators

Petition 870160077664, of 12/21/2016, p. 9/21 / 8 are very close and block the movement of the door until the end of its regular course.

[004] To resolve this issue, the same holder of the document on screen, through document BR102014018577-1, whose patent application was filed on 07/28/2014, allowed the damping of the movement of closing sliding doors, with the tension of the spring adjusted according to the weight of the door. Thus, the damping is activated by the used guide fixed to the door, which acts as a trigger or fisherman, which is integrated into the damper in order to allow complete movement of small doors, even in situations where dampers are installed in both. sides.

[005] It happens that the shock absorber revealed in the document above is manufactured from a housing assembled by the fitting of several parts, which makes the industrial process more complex and time consuming. In addition, the spring has its own constraints to fit the regulator, differently from what is proposed in this document.

[006] In addition, the trigger does not include any silencing elements, nor does it have a pre-assembly and assembly mechanism, which makes the object not very silent during use and requires the assembler, obligatorily, to correct the initial manual activation for continuity. using the device. If this does not occur, the manual initial activation does not occur, due to the assembler's forgetting, for example, the device will not work.

Inventive Concept:

[007] The present Constructive Arrangement in Furniture Damper and Actuator Set that can be used with

Petition 870160077664, of 12/21/2016, p. 10/21 / 8 wooden or aluminum doors, together with 26mm, 28mm or 32mm rails.

[008] The differential of this utility model refers to the possibility of fine adjustment in the adjustment of the spring tension, providing precision in closing the door and lightness in its opening. This adjustment can be made with a screwdriver, moving a clip itself laterally, increasing and decreasing the tension of the spring according to the weight of the door. The fitting of the spring is done through the clipping element, an innovative situation that guarantees less maintenance and more safety when engaging the spring. The spring tension adjustment can be done with a damper already installed, without having to remove the door or the damper itself.

[009] In addition, it has a graduated actuator that allows the correct alignment with the damper, regardless of the thickness of the door, that is, the form of fixation allows its proper positioning in the furniture box in a quick and practical way by the installer, minimizing the risk of errors.

[010] The trigger itself has bilateral stops with a silencer function, that is, they provide a reduction in noise when the damper actuator is fitted between said stops. Considering multiple actuations by the user, at times, this noise reduction becomes an important differential.

[01 1] For the operation of the dampers in general, it is recommended that it be pre-actuated, that is, that the trigger is fitted to the body of the damper and the spring is fully tensioned. If this pre-activation does not occur, the damper will not work correctly. To solve this problem, the developed trigger has a pre-activation hook, which, in the first contact with the trigger, this

Petition 870160077664, of 12/21/2016, p. 11/21 / 8 moves the trigger to the correct initial position, avoiding installation error situations. In situations where the shock absorber trips during use, due to adverse situations, this pre-activation is used as self-activation, in the same way, avoiding the need for an own assembler to go on site, this self-activation being performed by the user.

[012] The developed shock absorber also has a single housing, that is, a single part is injected to assemble the shock absorber, which facilitates manufacturing and makes it faster and at a lower cost.

Application field:

[013] The application of this Constructive Arrangement in the Assembly of the Shock Absorber and Actuator for Furniture occurs in the use of this as an upper shock absorber next to sliding doors for cabinets with support at the base, in order to avoid the impact of the doors on the stops and lateral structures , in its opening and closing, being, therefore, an accessory for furniture.

Benefits:

[014] The Constructive Arrangement of the Shock Absorber and Actuator for Furniture presents with advantages:

• Possibility to avoid side collision between sliding doors and door frames or side structures of the furniture, avoiding damage to the doors and the furniture structure, which reduces maintenance and guarantees an increase in the service life of the furniture and the sliding system.

• Provides closing and / or opening of the furniture doors in a comfortable, smooth, safe and silent manner;

• In particular, a very low noise level was obtained when the trigger was engaged on the trigger, provided by the silencer;

Petition 870160077664, of 12/21/2016, p. 12/21 / 8 • Ease of installation and replacement, since the device contains the means of fixation by screws, and the actuator contemplates graduation for positioning for application in different door thicknesses;

• It allows the pre-activation of the damper by the device itself, carried out at the moment when the first contact of the trigger with the trigger occurs, which moves the trigger to the position fitted in the damper's own span, tensioning the spring;

• Installation flexibility, as the device can be installed on wooden or aluminum sliding doors, in addition to being able to be fixed on the most diverse types of upper rails;

• Installation flexibility, since the same damper can be installed in the upper left or right part of the door, depending on the constructive form of the furniture (which side the doors open), just for the correct placement of the fasteners;

• It allows greater smoothness of movement when opening the door, provided by the fact that the damping occurs through the opening of the telescopic piston, which requires less force from the user to return the trigger to its original position;

• Lower manufacturing costs for the shock absorber, as it is a single housing;

• Satisfactory final aesthetic quality of the furniture, since the stop is fixed on the upper side of the rail through which the doors run, being hidden, without interfering in the final aesthetic of the furniture as a whole;

• If the shock absorber disarms due to misuse, the fact that it has the trigger with self-activation allows the user to arm it again, making the movement

Description:

[01 6] The Constructive Arrangement in Assembly of Shock Absorber and Actuator for Furniture consists of the shock absorber (1) formed by the single housing (2), which has the fixing holes (3) in order to allow the shock absorber to be fixed

Petition 870160077664, of 12/21/2016, p. 14/21 / 8 on the top rail. This fixation is made by screw and can be alternated between the left and right end of the damper, depending on its installation position, that is, on the left or right side of the door.

[017] The damper (1) also has a telescopic piston (4) that is placed internally in the single housing (2) and is provided with a tip (5) that connects to the trigger (6) through the hole (7). The spring (8) fits into the single housing (2) through the clip (9) and the engagement (10) of the trigger (6). For fitting the spring (8), the clip (9) has the grooves (1 1) in it, as well as the upper groove (1 2) used to adjust the spring tension using a screwdriver. The projection (13) of the clip (9) acts as a movement limiter for adjustment, in the rectangular opening (1 4), of the regulator (15).

[01 8] The adjustment of the spring tension is made in the regulator (1 5) that has protrusions (1 6), type scales, and through the positioning of the clip (9) to the left or right, increasing or decreasing the tension of the spring (8), allowing its fine adjustment according to the weight of the door.

[01 9] The trigger (6), during the actuation of the shock absorber fits into the gap (17) of the single housing (2), in order to open the telescopic piston (4) so that, when the shock absorber is activated ( 1), said telescopic piston (4) soften and smooth the closing movement of the door.

[020] The trigger (6) has a central span (1 8) equipped bilaterally with silencers (1 9), preferably made of rubberized material, fitted into the circular couplings (20) between which the actuator will be positioned (21). The hook (22) of the trigger (6) acts for the self-activation of the damper, since, to start operation, the trigger (6) needs to

Petition 870160077664, of 12/21/2016, p. 15/21 / 8 be fitted in the gap (17) of the single housing (2), keeping the telescopic piston (4) open.

[021] The actuator (21) is the element responsible for activating the trigger (6) of the shock absorber (1). It is fixed on the furniture door and promotes the movement of the telescopic piston (4), making the opening or closing of the door to occur smoothly. The actuator (21) consists of a housing (23), the oblong positioning holes (24) used for fixing, and the graduation template (25) that allows the fixation adjustment on the top of the door according to the thickness of the same (26mm, 28mm or 32mm) and by the protruding rectangular element (26), orthogonal, provided with the grooves (27).

[022] The assembly and self-activation occurs as follows: the driver (21) is fixed to the door according to the thickness of the rail and the graduation template (25), the damper (1) is fixed to the upper rail of the furniture ; the door is placed on the furniture and, when closing, the actuator (21) passes through the damper (1) so that the protruding rectangular element (26) has its grooves (27) engaged with the hook (22) of the trigger (6), moving the trigger (6) until it fits into the gap (17) of the single housing (2), keeping the telescopic piston (4) open.

[023} Thus, whenever the door is closed, the damper will be activated, making the closing smooth and continuous, and when the door is opened, the damper is again positioned to be used in the sequence. Conclusion:

[024] In this way, the Constructive Arrangement in Shock Absorber for Sliding Door, is subsidized by unprecedented technical and functional characteristics, as can be seen in the attached figures and understood in the specification, thus deserving the legal protection sought.
