Description

DEVICE AND METHOD FOR CONTROLLED DOOR CLOSING
DESCRIPTION OF INVENTION
Field of Technology
Closing of doors on stoves and other cooking appliances; closing of doors on kitchen appliances; hinges for door closing; suspension; damping.
Technical Problem
The devices for industrial or domestic use are becoming increasingly more advanced. In order to ensure competitiveness on the market, increasingly improved devices must be manufactured for reasonable costs, and appropriate components must be ensured for the assembly of such devices, the manufacturing or purchasing costs of which should allow their integration into the product.
With kitchen appliances, such as stoves, ovens, dishwashers and refrigerator and freezer units, hinges must be installed to:
- ensure the required force through the entire area of door opening, since the doors on these appliances have a rather large mass due to their dimensions. With inappropriate hinges, in particular in the event of fast door opening with the fully opened (approximately 90°) or fully closed angle (0°), a thrust on the hinges and on the appliance may occur;
- ensure an appropriate force of door closing, which means that the hinge in the closed door position contributes to the pressure of the door on the kitchen appliance seal, which ensures a better and more durable sealing of the door;
- ensure a soft closing and opening of the door;
- ensure a possibility of a stable position of opening at a medium angle of door opening ("grill position"); - hinges must have small dimensions, long lifetime and be affordable, while their possible servicing must be as simple as possible.
State of the Art
Door closing hinges are generally well known, since they have been on the market for decades. More advanced types of hinges have also been used for decades, both for controlled closing of builders' joinery, closing of vehicle door, as well as closing of various devices.
The doors on some devices, such as a stove and a dishwasher, open downwards, whereby the hinges must be installed on the axle or near the axle that joins the device with its door. In addition to the appropriate load-bearing capacity, the hinge must also ensure an even adjusting of the angle between the device and the device door.
EP 1287222 displays a modern solution of controlled closing of stove door. An even door closing is provided by the curved section in the latch, designed to distribute the load more evenly through the entire area of opening of the stove door. For a proper operation, an additional guide track in the hinge is installed to ensure the proper position of the guide rod. In addition, the said patent does not solve the problem of damping for a soft door opening or closing. In EP2284344 and US2010148646, the problem of a more even transfer of load from the translatory movement into a suitable movement for door opening is solved by a curved section on the so-called moving arm (an added external element with a formed curved section) which allows the movement of the roller.
The device according to the invention ensures a sufficient force throughout the entire working range of the hinge and an additional functionality of the simple model of the hinge, which is composed of a small number of components that can assembled in a simple manner; the hinge can be easily installed, while its construction is robust, which ensures a long service life.
Description of new invention
The object of the invention is the device and method for controlled door closing, whereby the technical solution is functional, technologically suitable for production, economical, strong and reliable throughout the expected service life. The invention also ensures fast and simple mounting of the door closing hinge on the appliance as well as the appliance door. The object of the invention can be used for controlled closing of any type of doors, leaves or windows, while it is preferably designed for installation kitchen appliances, such as a stove, an oven, a 'built-in cooking appliance, a dishwasher, cooling and other appliances.
The object of the invention solves the technical problem of controlled door closing, whereby:
- an even transfer of the translatory load of the spring is achieved by a curved section that is provided in the hinge body or the component of the hinge body;
the curved section guides a piece, and its movement is connected to the movement of the latch and the guide rod;
the curved section is designed in such a manner to:
ensure additional pressure on the appliance or its seal during the closing of the door;
ensure a stable position of the door at a predefined angle of opening;
ensure balancing of the door from the stable position (the grill position in the specified angle) to the open position (at approximately 90°).
The object of the invention comprises also the installation of one, two or more dampers for reducing the loads (forces and vibrations) directed at the axles of the spring guide. The damper is installed in such a manner to absorb mainly the loads that are generated by the closing or opening of the door and also absorbs the loads that are generated at the angle of the last few degrees of door closing or opening.
In addition to the provided curved section which ensures a controlled closing of the door, the damper additionally contributes to a soft (gentle) closing of the door. The function of soft closing of the door is effective at the any desired angle of the door, which depends on the setting.
In some places, the curved section is installed in the hinge body in such a manner to ensure stable positions. The initial opening position of the appliance door includes a small projection on the fitted curved section, which requires a pre-adjusted initial force at the initial opening position, while at the same time ensures a stronger pressure of the door on the seal to provide better sealing. Furthermore, a recess is provided on the provided curved section, ensuring a stable position in a certain predefined angle of closing of the appliance door.
A small spring is inserted in the spring guide to prevent a forceful dropping of the door due to increased torque at an angle before the fully open position (approximately 90°), which consequently prevents damages at a forceful opening and lowering of the door. On one (upper) side the small spring is fitted in the interior of the spring guide, while on the other (lower) side the small spring is fitted in the spring fit.
The damper is installed in the device according to the invention in such a manner that it does not increase the exterior dimensions of the device, but is installed in the interior of the spring guide that is flexibly connected to the hinge body. In the damping function, the movement of one (upper) side of the damper is limited by the lower side of the spring fit, while on the other (lower) side, the movement of the damper is limited by the mechanical part inserted in the latch, preferably by the projection on the connecting link.
The device according to the invention is compact, robust and has few components and comprises at least:
- a hinge body with a fitted curved section for controlled transfer of load;
- a spring fit, which can be an independent part or integrated into the hinge body;
- a spring;
- a spring guide;
- at least one part that moves on the curved section fitted in the hinge body, whereby this can be an independent piece, preferably a roller, or provided as a part of another component, for example a spring guide;
- a latch;
- a fixed rotating axle of the latch, which connects the latch with the body; and
- a removable blocking part for fixing the door on the appliance.
Furthermore, the device according to the invention can comprise:
- one, two or more dampers; - a spring stop for limiting the upper position of the spring, which can be fitted in the form of a plate or in any other manner; and
- a small spring inside the spring guide.
A curved section, preferably U-shaped, is fitted in the hinge body, and is designed to ensure a controlled transfer of loads during the conversion of the translatory load of the spring into a suitable load at the circular movement. A curved section can be fitted into the hinge body as a hole through the material of the hinge body, as a recess in the material of the hinge body, as an indentation in the material of the hinge body without removing any material or in any other manner. A spring fit is installed at the upper part of the body. The spring fit can be made of any material, while preferably it is made of plastic material. The spring fit is equipped with a suitably shaped one or more openings, which allows the movement of the spring guide. The diameter of the spring exceeds the diameter of the spring guide, so that the spring fits on the spring fit at a greater radius (in relation to the spring guide axle) than the provided openings which allow the movement of the spring guide. The diameter of the small spring is smaller than the diameter of the spring guide, so that the small spring fits on the spring fit at a smaller radius (in relation to the spring guide axle) than the provided openings which allow the movement of the spring guide. The spring fit is removable, but is fixed in the hinge body.
The upper part of the spring guide or the spring is limited by a spring stop, preferably a plate, which limits the movement of the spring, while the lower part of the spring guide or the extension of the spring guide is finished by a piece that moves on the curved section fitted in the hinge body. The piece that moves on the curved section fitted in the hinge body is preferably constructed in such a manner that a roller is installed on the axle which runs perpendicular to the guide axle, ensuring easier movement on the curved section fitted in the hinge body, or that two rollers are mounted on the said axle, whereby each roller moves on its own curved section fitted on both sides of the body. A roller or rollers are pivo tally riveted to their axles.
The latch is mounted on the hinge body with a fixed pivot. The movement of the latch is guided by the axle of the piece, preferably the axle of the roller, which moves on the curved section fitted in the hinge body, whereby the load is transferred to the latch. The movement of the latch can be connected to the movement of the axle of the piece in such a manner that:
- a connecting link is installed in between, on one side connected to the roller axle and on the other side connected to the axle with a latch. The connecting link is provided to transfer the movement and load from the axle of the piece to the latch;
the axle of the piece travels on the relevant external surface of the latch which can be additionally shaped in the form of a curve, thus having an additional effect on the movement of the door or the transfer of load from the door to the appliance.
The kinematics of movement of all the components of the device according to this invention is determined by the position of:
the mounting axle of the latch to the hinge body, which enables the rotation of the latch about the axle; and
- the axle of the piece, to which the piece that moves on the curved section fitted in the hinge body is mounted.
The mounting axle of the latch and the axle of the piece are always at the same distance from the flexible axle of the latch, regardless of the position of the latch. The mounting axle of the latch may be constructed in such a manner that a latch bush is installed though the latch rivet, riveted though the hinge body, which enables a circular movement about the mounting axle of the latch. An axle bush of the piece is installed on the axle of the piece, facilitating the circular movement between the axle of the roller and the connecting link through which the axle of the roller is fitted.
The other side of the latch is intended for mounting the door on the appliance and at the same time transferring the load from the door to the appliance, as well as providing the load-bearing function of the door. A door locking part is mounted on the latch to prevent the door from dropping down during closing.
One, two or more dampers can be installed in the device according to the invention. A damper is preferably installed below the spring fit in the spring guide above the axle of the piece which moves on the curved section. The essence of the invention is further explained below with the description of the embodiment and attached figures, whereby the figures are part of this patent application and show the following:
