Description

  The present invention relates to an apparatus (close / damping device) for closing and damping a movable part of furniture, in particular, a displaceable (openable and closable) sliding door of furniture according to the premise of claim 1. .

Such closing and damping devices are known from various embodiments of the prior art. Such a closing / vibration control device is used particularly for furniture having a sliding door, and automatically pulls the sliding door back from a predetermined position to a closed position.
In particular, when a tension spring is used as an energy storage device for such a closing / vibration control device, the tension spring is caused by the linearity of the spring characteristics of the tension spring when opening a movable part of furniture such as a sliding door. A relatively large acting force is required to extend the length to a predetermined length.
In order to minimize the force required to open the sliding door and / or reduce the slope of the spring characteristic curve, the conventional solution used a tension spring that is as long as possible that can be wound in the housing. . It is also known to provide a plurality of connected tension springs and / or compression springs instead.

An object of the present invention is to provide a closing / vibration control device for moving parts of furniture, in which a force required for an opening operation is small and / or a slope of a spring characteristic curve is small.
The object of the present invention is to provide a closing / vibration device for moving parts of furniture having the characteristics of claim 1 and for moving parts of furniture having the characteristics of claim 8. This is achieved by the closing and damping device.

The closing and damping device according to the present invention is provided with an energy accumulator, and a first end of the energy accumulator is attached to the housing. Specifically, the energy store has the form of a tension spring, and during the opening operation of furniture moving parts, the energy store extends and during the closing operation the force stored in the energy store is Used as an aid to pull the moving parts of the furniture back to their final closed position. Further, such a closed / vibration control device includes a vibration control device having a form of a vibration control device such as a pneumatic type or a hydraulic type.
The second end of the energy store is coupled with a deflector. The deflector includes a gear, a toothed rack that meshes with the gear, and a holding device that is non-rotatably secured to the gear (ie, secured to rotate with the gear). According to the invention, the deflector comprises a winding curved surface for changing the distance of the rotation center point of the gear from the anchor point of the energy store during the opening and closing operation. When a moving piece of furniture, specifically a sliding door, is opened to the furniture, the driver pushes the toothed rack, the toothed rack drives the gear, and the energy store is around the winding curved surface. Wrapped around. This causes the effective lever arm length at the mooring point at one end of the energy accumulator wound around the gear to change due to the shape of the winding curved surface. This means that less force is applied during the opening operation compared to conventional solutions, and when the tension spring is used as an energy store, the spring characteristic curve is flatter, In other words, it means horizontal or slightly downward.

Advantageous embodiments of the invention are indicated in the dependent claims.
According to a preferred embodiment, the holding device is provided with a winding curved surface that serves as a spiral bearing, and in the closed position of the bearing, the anchor point of the energy accumulator is maximized from the center of rotation of the gear. Is in the distance.
According to another advantageous embodiment, the end of the energy store coupled with the holding device is made as a cable or a straight wire. This means that the energy accumulator can be easily attached to the holding device, since ideally the cable or straight wire is formed in such a length that only the cable or straight wire contacts the holding device. Means.

According to another advantageous embodiment of the invention, the closed / vibrating device has an elliptical gear, the width of the toothed rack is such that the toothed rack meshes with the gear at the open position of the closed / vibrated device. It is wider in the zone where the toothed rack meshes with the gear in the closed position of the closing / vibration control device than in the closed zone. The gear and / or toothed rack in such an embodiment has a reverse torque of the energy store in the closed position of the gear that is greater than the reverse torque of the energy store in the open position of the gear. . As with the winding technology itself, this compensates for the enormous energy of the taut energy store. In this embodiment, the combination of winding technology and teeth rotating around the curved surface maximizes the effect of minimizing the energy required for the opening operation according to the lever principle.
According to another embodiment, the closing and damping device attaches the first end of the energy accumulator to the housing and connects the second end between the ends of the energy accumulator during the opening / closing operation. It is configured to be coupled with a deflector so as to always maintain its linearity. This means that the energy store is not so taut as the moving parts of the furniture are gradually opened during the opening operation. Especially when a tension spring is used as the energy store, the energy store is extended by a distance less than the distance that the toothed rack is displaced, or less than if the energy store is warped or wound. . Even in this embodiment of the present invention, the amount of energy required for the opening operation is smaller and the spring characteristic curve is flat compared to the conventional solutions.

In the description of the figures below, terms such as upper, lower, left side, right side, front side, rear side, etc. represent expressions selected in respective exemplary drawings such as closing / vibration control devices, energy storage devices, deflectors, etc. It is only a reference to the position. These terms are not limiting, and these representations may change accordingly if the working position is different or the arrangement is symmetrical, such as a mirror arrangement.
In FIG. 3, reference numeral 1 denotes a closed / vibration control for the sliding door 15 that can be replaced with a movable part of the furniture according to the embodiment of the present invention, in particular, a part of the furniture 12 shown in FIGS. 6 and 7. The entire device is shown. Further, as can be seen from FIGS. 1 and 2, the closing / vibration control device 1 is provided with a driver 4. When the closing / vibration control device 1 is attached to the furniture body 12, the activator disposed on the sliding door 15 engages with the driver 4. When the sliding door 15 is opened and the energy storage 6 is extended, the activator pushes the driver 4 along the guide slots 23 and 33 of the housing of the closing and damping device 1. The energy store 6, which is preferably provided as a tension spring, has a first end 61 attached to the housings 2, 3. The other end 62 of the energy accumulator 6 is taut during the operation of opening the movable part of the furniture, for example, the sliding door 15 shown in FIG. 7, and is accumulated in the energy accumulator 6. The energy is used as an aid in pulling the sliding door 15 back to the final closed position during the next closing operation. The other end 62 of the energy store 6 is coupled to the deflector 5. The deflector 5 basically includes a gear 52, a toothed rack 51 that meshes with the gear 52, and a holding device 53 that is non-rotatably disposed on the gear 52.

FIG. 4 shows the closing and damping device 1 in the closed position, and FIG. 5 shows the closed position after the activator held by the sliding door 15 is no longer engaged with the driver 4. A closing and damping device 1 is shown. In the closed position shown in FIG. 4, the energy store 6 is not in a substantially tensioned state. The holding device 53 of the deflector 5 is in a position where the end 62 of the energy storage 6 attached to the holding device 53 can be deflected once again. When the sliding door 15 is opened, pressure is applied to the toothed rack 51 via the coupling 8 by the driver 4.
At the front end portion of the toothed rack 51, teeth 511 that mesh with the teeth of the gear 52 are provided. When the toothed rack 51 is displaced (to the right in FIGS. 4 and 5), it is non-rotatably attached to the gear 52 and thus to the gear 52 (ie, attached to rotate with the gear 52). The holding device 53 rotates clockwise so that the distance of the rotation center point 521 of the gear 52 from the mooring point of the energy accumulator 6 changes during the opening operation, more specifically, it decreases during the opening operation. The energy storage 6 is warped and pulled. By reducing this distance, the effective lever arm length is shortened, so that the amount of energy required to tension the energy accumulator 6 can be reduced.

In this way, by reducing the resistance when the sliding door is opened, the driver 4 is in the opening movement from the state where the driver 4 is engaged with the activator of the sliding door to the state where the sliding door is released. The sliding door moves smoothly. In the conventional known solution, the resistance is abruptly reduced when the activator is released from the driver 4.
According to the embodiment described in FIGS. 1 to 4, the holding device 53 is attached to the gear 52 so that the energy accumulator rides on the helical bearing 531 when wound around the holding device 53. The helical shape is oriented so that the distance of the bearing 531 from the rotation center point 521 of the gear 52 is maximized when the gear 52 or the holding device 53 is in the closed position. Decreases as it is wound around the holding device 53 gradually.
The closing / damping device 1 is further provided with a damping device 7. Specifically, the damping device 7 is provided as a gas or hydraulic damping device, and one end of the push rod 71 extends into the tightly sealed housing of the damping device. The other end of 71 is fixed to the housings 2 and 3 of the closing and damping device 1. The housing of the damping device 7 is coupled to the toothed rack 51 and is carried along when the driver 4 is displaced along the guide slots 24, 34 of the housing 2, 3 of the closing and damping device 1. Yes. Preferably, the toothed rack 51 is guided in the guide slots 24 and 34 by two guide pins 513 engaged with the guide slots 24 and 33 of the housings 2 and 3 of the closing and damping device 1. These two guide pins 513 are molded or attached to the toothed rack 51.
The two members 2, 3 forming the housing of the closing / vibration control device 1 are preferably screwed together. For this configuration, threaded openings are preferably formed in the four corners of the rectangular housings 2 and 3 and the housing halves 2 and 3 can be connected by screwing in the screws 11. It can be done. The closing and damping device 1 can be screwed to the furniture using two further openings 25, 35 of the housings 2, 3.

6 and 7 show the closing / vibration control device 1 in a state of being attached to furniture. 6 and 7 show a part of the sliding door cabinet. A sliding door 15 is suspended from the rail 13 by a roller 16, and when the sliding door 15 is in the closed position, the roller 16 is connected to the rail 13. It has been shown that it can be secured to the restraining device 14 at the end.
8 to 11 show a closing / vibration control device 1 according to another embodiment of the present invention. According to FIGS. 8 to 11, although the spiral bearing is not provided in the holding device 53, the holding device 53 basically has a circular shape in which the tongue-shaped holding portion 532 extends along the radial direction. It is served as a board. The second end 62 of the energy accumulator 6 is attached to this circular plate. Preferably, the energy accumulator 6 is rotatably mounted on a deflector 5, in particular a rotation axis oriented parallel to the rotation axis of the gear 52.
As can be seen from FIGS. 10 and 11, when the closing and damping device moves from the closed position to the open position and the driver 4 is displaced by the coupling 8 of the toothed rack 51 that engages the gear 52, the energy storage. The entire vessel 6 is swung downwardly about the energy storage suspension point at the first end 61 of the energy storage. This causes the energy accumulator 6, preferably serving as a tension spring, to bend for a shorter distance than for the entire distance that the toothed rack 51 is displaced. This is because the second end 62 of the energy store 6 is connected to a holding device 53, specifically a holding tongue 532 that extends radially outwardly. Therefore, it moves so as to draw a circle rather than linearly displace.

12 and 13 show a closing / vibration control device 1 according to another embodiment of the present invention. In this case, in contrast to the embodiment described in FIGS. 1 to 4, the energy storage 6 is not provided as a whole as a tension spring, but rather a functional connection zone to the holding device 53. In FIG. 13, it is provided as a cable or a straight wire 63 and is wound around the holding device 53 when the toothed rack 51 is moved from the closed position to the open position (FIG. 13).
In another further alternative, shown in FIGS. 19 and 20, the energy store 6 is provided as a strap 64 in the area of the functional connection zone to the holding device 53. This strap is wrapped around the holding device 53 when the toothed rack 51 moves from the closed position to the open position (FIG. 13), similar to the embodiment described with respect to FIGS. The strap 64 is specifically provided as a hinged part made of plastic film, but it is contemplated that it may be a woven strap made of plastic, textile or thin metal. Preferably, the strap 64 is provided as a separate piece connected on one side to the holding device 53 of the gear 52 and on the other side to the energy storage 6.

15 and 18 show a closing and damping device 1 according to another advantageous embodiment of the invention. In this case, in contrast to the previous embodiment, the gear 52 is elliptical rather than circular. Accordingly, a toothed rack, more precisely, a toothed region 511 of the toothed rack 51 is provided as an inclined edge. This is because the width of the toothed rack 51 in the plane perpendicular to the rotational axis 521 of the gear 52 is larger than that in the zone where the toothed rack 51 is engaged with the gear 52 at the open position of the vibration damping device 1. This also means that the zone in which the toothed rack 51 meshes with the gear 52 is wider in the closed position of the closing / damping device 1.
FIG. 14 shows a force-path characteristic curve (characteristic curve A) of a conventional closing device known as an automatic closing device in the prior art and a force-path characteristic curve of the closing / vibration control device 1 according to the present invention. The comparison with (characteristic curve B) is clearly shown. In the case of the characteristic curve B, as the warp s increases, the force F required for the warp continuously decreases, but in the case of the conventional closing / vibration control device indicated by the characteristic curve A, if the tension spring warps. The greater the force F, the more it will warp.
