Description

Detailed Description of the Invention

  The present invention is directed to an improved guide device for opening and supporting furniture doors.

  More specifically, the present invention relates to a guide / support device for guiding and supporting door movement during opening and closing, which is suitable for application to furniture with an openable door.

  As is well known, furniture with openable fall front doors, such as cupboards, shoeboxes, bathroom and kitchen cabinets, and similar furniture, usually connects the door to the furniture frame. The door can be opened and closed by the hinge mechanism arranged to do so.

  The user manually opens and opens the door, and typically places the hand on the door again when closing the door.

  However, the user may operate the door with excessive force, release his hand, or the door will give a fluctuating and violent impact to the furniture frame so that the door does not touch the door. Sometimes it doesn't close. This causes wear and damage to the furniture, and causes problems such as a safety problem (risk of the user hitting the door) and / or lack of aesthetics when the door is in a half-open state.

  In order to eliminate this drawback, a vibration-reducing hinge connection, for example, a hinge connection that includes a guide device including a pneumatic spring that is easy to open and close the door and is suitable for absorbing shocks, or More generally, a hinge connection with a mechanism suitable for allowing the door to slowly return to the closed position has been proposed.

  Also, as another structural solution, use a hinge mechanism with a hinge mechanism with a lever or a coupling system (for example, a quadrilateral coupling system with joints) having a vibration control means for controlling the opening / closing operation of the door. There is a way to do it.

  However, these structural solutions involve significant drawbacks associated with increased structural complexity and dimensions due to the presence of insulators, and associated costs.

  Further, as another simple structural solution, a method of guiding the opening / closing operation of the door by the support structure attached to the frame and projecting the cable and the cable connected to the door (for example, the present applicant) EP 1691016A1 and DE-202008002232UL).

  However, even if these devices have a simpler structure than the above-mentioned structure, the cable has a large disadvantage related to the total length of the structure, and the size of the door and the inclination of the door when it is opened. There are major drawbacks associated with the need to accurately calculate the length. As a result, these devices cannot be used to guide the operation of the door for furniture with a small depth dimension that cannot be cabled on one side of the device, such as a shoe box, for example.

  In addition, the last conventional guide device is particularly adapted to be applied to one side (right side or left side) of furniture or a single orientation, and as a result, has some inventory in the warehouse There is a further disadvantage that the need arises and the associated costs increase.

  The object of the present invention is to avoid the above drawbacks. More specifically, it is an object of the present invention to provide an improved guide device for opening and supporting furniture doors, particularly of reduced overall dimensions so that it can be used for various types of furniture, for example shoeboxes. It is an object of the present invention to provide an improved guide device that does not limit the effective space of furniture with a shallow depth, such as a cabinet for a bathroom or a bathroom.

  A further object of the present invention is to provide a guide device that can be used in various directions regardless of the left and right sides of the furniture.

  It is a further object of the present invention to open and support a furniture fall front door that is suitable for ensuring high durability and reliability over time and can be manufactured simply and economically. An improved guide device is provided.

  A further object of the device of the present invention is to reduce the manufacturing cost of the guide device by saving the material of the guide device, in particular the material of the cable for supporting the door.

  The above and other objects are achieved by the present invention having the features of claim 1.

The sheet 42 is disposed at the position of the through hole 41.

  The first half shell 24 and the second half shell 26 including the internal parts described above are connected to each other by screws, pins, snap-type holding elements, or similar known ones that suit the purpose. Is done.

  The improved guide device of the present invention for opening and supporting furniture doors has been described in detail above with reference to its structural features, the function of which will be described below.

  Referring to FIG. 1, the furniture with the door 16 closed is schematically shown.

  In this state, the body slider 48 is completely rearward, the cable 20 is wound around the gear 52, the helical spring 58 is stationary, and the rear of the damping element 56 is the shoulder or joint. 45 is in contact.

  When the user opens the door 16 (as shown by the arrow A in FIG. 3 which shows a configuration with the door fully opened), the cable 52 connected to the door 16 is pulled, so that the gear 52 While unwinding and simultaneously, the main body slider 48 is moved in the direction of the pulley 60 and the helical spring 58 is compressed, so that the main body slider 48 rotates relative to the cog-shaped contour, that is, the rack 32.

  The impact that may occur at the end of the stroke in the door opening stage is damped by the operation of the damping element 56. In the damping element 56, the front end or front portion of the casing 56 ″ of the damper 56 ′ comes into contact with the first pusher 62 disposed in the other first lobe 44 and subsequently compresses the damper. Absorbs shock.

  Similarly, when the door 16 is closed, the gear 52 rotates and moves relative to the cog-shaped contour, that is, the rack 32 in the direction opposite to the starting direction due to the effect of the return operation of the spiral spring 58. As a result, the main body slider 48 storing the gear moves, and at the same time, the cable 20 is wound around the gear.

  In this case, the damping element 56 contacts the shoulder portion, that is, the coupling portion 45, and absorbs the impact of the main body slider 48 in the return stage.

  Further, the user introduces the tip of a tool, for example, a screw driver into the through hole 41 of the container body 11, so that the columnar end crown 70 of the first pin 66 and / or the second pin 68 has a tooth shape. Operations can be performed on the contour. By rotating the pin and rotating the first pusher 62 and / or the second pusher 64, the preload of the spiral spring 58 and / or the operation of the damping element that also has the function of limiting the opening of the door is adjusted. can do. This is useful for accurately determining the tilt of the door when it is opened, as well as for positioning the mechanism downwards if necessary.

  With respect to this structure and assembly configuration, the jockey pulley 60 may not be provided.

  The guide device of the present invention may be attached to furniture by being rotated by 90 °. That is, as shown in FIG. 7 and FIG. 8, it may be attached at a vertical position with respect to the horizontal position described above. This configuration is particularly suitable for application to furniture with a shallow depth. The function of the guide device is generally the same as that described above.

  In this case, the jockey pulley 60 is always provided in order to accurately guide the cable 20 and to secure the tension of the cable 20.

  The advantages achieved by the device of the present invention are evident as described above.

  The improved guide device of the present invention for opening and supporting furniture doors can advantageously reduce the diameter of the gear around which the cable 20 is wound, thanks to the rotational movement of the gear relative to the rack. The length can be suitably shortened. This is because a part of the cable length is compensated by the displacement of the gears along the rack.

  A further advantage is that the guide device according to the invention is suitable for being able to damp impacts both at the door opening phase (at the end of the opening stroke) and at the closing phase (at the end of the closing stroke). It means that it has a vibration means.

  A further advantage of the present invention is that it is possible to compensate for the weight of the door in the opening phase, and at the same time, an elastic element and a compression type helical spring are provided to reduce the effort for the user to lift the door in the closing phase. is there.

  A further advantage of the present invention is that the pins for adjusting the damping system are manipulated in order to accurately determine the opening inclination of the door and to accurately position the guide device relative to the furniture. It is possible to limit the rotational movement of the gear relative to the rack.

  A further advantage is that the guide device of the present invention is vertical, i.e. standard, so as to fit shallow furniture, e.g. shoeboxes, bathroom cabinets, etc. without the need for structural changes. This means that it may be rotated 90 ° with respect to a typical horizontal arrangement (based on the sliding direction of the main body slider 48).

  A further advantage of the present invention is that the two half shells defining the container body of the guide device of the present invention are equivalent and symmetrical to each other so that the device is mounted on both the right and left shoulders of the furniture frame. This means that there is no need to provide a left guide device and a right guide device.

  Although the present invention has been described above with particular reference to one embodiment of the present invention and with reference to non-limiting examples, it will be appreciated by those skilled in the art that all modifications and variations are possible in light of the above description. it is obvious.
