Abstract

The objective of the present invention is to provide a slide damper which can be easily installed even in a small installation space since the total size of a damping apparatus can be reduced by being manufactured not only easily and cheaply with a simple structure but also in a block type, because a rotary damper is used as a unit to buffer force of moving in a sliding manner like a window or a furniture door performing a linear motion or rotary motion. Also, another objective of the present invention is to provide a slide damper which is configured to rotate a rotating body by kinetic energy of an operation tool performing a rotary motion or a linear motion. At this time, the rotating body performs damping operation when being rotated in one direction, and does not perform damping when being rotated in another direction. Thus, the slide damping apparatus can reduce the installation space by reducing the size of the damper itself and also can perform damping operation regardless of the window or a slide body performing the linear motion or the rotary motion. In addition to this, the other objective of the present invention is to provide a slide damper which can increase damping efficiency since the damping apparatus can be manufactured in a block type and can be configured for the rotating body rotating for damping to receive strong resistance of a working fluid while reducing the total size thereof.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should properly define the concept of the term to describe its invention in the best possible way The present invention should be construed in accordance with the spirit and scope of the present invention.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Thus, various equivalents And variations may be present.

A slide type damping device according to [Embodiment 1] of the present invention includes a main body 100, a slider 200, a tension spring 300, a stopper 400, and a key 500.

Particularly, according to the present invention, as the key 500 moves, the stopper 400 is rotated to move the slider 200, which receives elastic support of the tension spring 300, in the main body 100, A rotary damper (D) changes a linear motion to a rotary motion, and a damping action is performed.

Hereinafter, this configuration will be described in more detail.

The main body 100 constitutes a mounting space 110 of a predetermined size as shown in Figs. 1 to 3. The mounting space 110 is a space for accommodating another configuration to be described later, and is formed to have a size sufficient to prevent interference when the other configuration is moved.

At least one guide 120 and at least one sliding guide 130 are formed on the main body 100 in parallel with each other as shown in FIGS. 1 to 3. Particularly, the guide 120 is formed with an engagement groove 121 on one side thereof, and the stopper 400, which is guided by the guide 120, is engaged with the engagement groove 121 while being rotated. This configuration will be described in detail again while explaining the stopper 400 and the key 500.

Finally, the main body 100 is equipped with at least one rotary damper D, which acts as a damping action as the gear 50 rotates, as shown in FIGS. 1 to 3. Although one rotary damper D may be used, it is preferable that two or four rotary dampers D are arranged side by side according to the intensity of the damping force. The figure shows an example in which two are arranged side by side. The detailed structure of the rotary damper D will be described later.

The slider 200 is formed integrally with the guiding portion 210 and the actuating portion 220, as shown in Figs. 1 to 4. At this time, the guide portion 210 is installed on the sliding guide 130 and is guided by the guide.

In addition, the operating portion 220 is provided with a rack 221 so as to be engaged with the gear 50, as shown in Figs. 1 to 4. At this time, the rack 221 plays a role of converting the linear motion moving in the longitudinal direction of the slider 200 into the rotary motion of the gear 50 formed in the rotary damper D to be described later.

In the preferred embodiment of the present invention, when a plurality of dampers D are provided as shown in FIG. 4 (c), the rack 221 is at least one It is preferable to arrange such that the engagement can be released at the gear 50 of the gear mechanism. This is because the damping force when the two rotary dampers D are engaged is greater than the damping force when the two rotary dampers D are engaged with each other, for example. Thus, when the slider 200 is housed in the main body 10, So that the slider 200 moving along with the window by reducing the force is smoothly and smoothly closed as well as opened easily when the window is opened again. In the figure, two rotary dampers (D) are provided, and only one of the gears (50) is disengaged to reduce the damping force by half. This is because the total number of the rotary dampers (D) It will be readily apparent to those skilled in the art that the present invention can be arbitrarily adjusted through the number of the elements to be released.

In the preferred embodiment of the present invention, it is preferable that the slider 200 further includes a sub rack 222 as shown in [FIG. 1] to [FIG. 4]. This is because when the rack 221 is disengaged from the gear 50 as described above as shown in Fig. 4 (c), there is a possibility that the disengaged gear 50 will idle. In this case, As the slider 200 moves, engagement with the gear 50 from which the rack 221 was released may not be performed smoothly. Thus, the present invention constitutes the sub rack 222, so that the gear 50, which is disengaged from the rack 221, can be easily engaged with the rack 221 again as shown in Fig. 4 (c) In order to align the position to come to.

The tension spring 300 is placed on the above-described sliding guide 130 so as to be movable in the longitudinal direction thereof, as shown in Figs. 1 to 4. At this time, the tension spring 300 fixes the both ends to the main body 100 and the slider 200 to provide an elastic force so that the slider 200 can move in parallel with the sliding guide 130.

The tension spring 300 may be of any type capable of providing an elastic force. In the drawing, a tension spring wound in a coil shape is shown as an example.

The stopper 400 is attached to the slider 200 described above so that the key 500 can rotate as the key 500 described below is linearly moved, as shown in Figs. 1 to 4.

Particularly, the stopper 400 forms the latching protrusion 410 on one side as shown in Fig. 2 and Fig. 3 (d). 4, the latching protrusion 410 is provided so as to move along the guide 120. At this time, the latching protrusion 410 is fitted in the guide 120 so as to move in the longitudinal direction and not to move in the width direction, The stopper 400 restricts rotation of the stopper 400 when the stopper 410 receives the guide 120 as shown in Fig. 4 (b). 4 (a)), the stopper 410 is positioned at a position where the stopper groove 121 formed at one side of the guide 120 is located, so that the stopper 400 is in contact with the key 500 It is caught in the latching groove 121 and is in the latching position. Such a latching action will be explained together with the key 500.

In addition, the stopper 400 is formed with an interference portion 420 on the outer periphery, as shown in FIGS. 2 to 4. The interference part 420 is configured to rotate the stopper 400 by interference with the key 500 as the key 500 linearly moves in a predetermined direction as shown in FIG. 3 (d) . 4 (a), the interference part 420 may be freely detached from the key 500 when the locking protrusion 410 is caught in the locking groove 121 (see FIG. 4 (b)), It is preferable that the locking protrusion 410 is formed on the guide 120 so that the key 500 can be retained.

When the window 500 is opened, the stopper 410 is engaged with the stopper groove 121 as shown in FIG. 4 (a) Away from it.

The key 500 is used to rotate the stopper 400 to cause a damping action as shown in Figs. 1 to 4, such as a door bracket normally attached to a window or the like, .

Particularly, the key 500 forms the fixing protrusion 510 so that the interference part 420 formed on the stopper 400 can be caught by the movement of the stopper 400 in parallel with the movement direction of the stopper 400. At this time, the fixing protrusion 510 interferes with the interference part 420 while being close to the stopper 400 as the window is opened and closed as shown in FIG. 4 (a), and the stopper 400 rotates . Thus, the guide protrusion 410 is guided by the guide 120 while being released from the engagement groove 121. At this time, the latching protrusion 410 receives the force to compress the stretched spring 300, and is guided along the guide 120, so that the window or the like is closed.

At this time, as shown in FIG. 4 (b), the locking protrusion 410 is caught by the guide 120 and can not move or rotate in the longitudinal direction thereof. As a result, the stopper 400 can not rotate, 510 are engaged with the interference portion 420 and move together to slide the slider 200 and consequently rotate the gear 50 of the rotary damper D so that the damping action is performed to close the window.

4, the key 500 is pulled to the left when the window 500 is opened. When the latching protrusion 410 comes to the position of the latching groove 121, the stopper 400 (FIG. 4 (a)), so that the latching protrusion 410 is caught in the latching groove 121. At this time, the interference part 420 is separated from the key 500 by the rotation of the stopper 400, so that the key 500 is separated as shown in FIG. 4 (a), and the window is opened. At the same time, the tension spring 300 is in the pulled state and provides the restoring force to the slider 200 when the window is closed again.

(Rotary Damper Configuration)

The rotary damper D according to the first embodiment of the present invention includes a main body 10, a rotating body 20, a shaft 30, at least two lock pins (40), and a gear (50).

Particularly, in the first embodiment, when the shaft 30 rotating together with the gear 50 rotates in a linear motion or a rotary motion, the lock pin 40 is rotated in either direction, 30 are rotated together to form a damping action. When the rotary pin 30 is rotated in the other direction, the rotary pin 30 and the shaft 30 are separated from each other.

Hereinafter, this configuration will be described in more detail.

The body 10 is formed in a block shape as shown in Figs. 5 to 8. At this time, since the main body 10 accommodates the later described rotating body 20, it is preferable that the main body 10 is formed in a shape similar to that of the rotating body 20, that is, a disk shape.

Particularly, the main body 10 forms an operating space 11 inside as shown in [FIG. 6] and [FIG. 7]. The working space 11 is formed in a circular disc shape to provide a space in which the rotating body 20 can be received and rotated. The working space 11 is formed to be slightly larger than the rotating body 20 so as to increase the damping effect when the rotating body 20 damps the working fluid by filling the working fluid. The working fluid at this time is preferably a normal oil flow used for a damping action in a normal damper.

The operation space 11 is formed such that one side thereof is opened to allow the rotator 20 to be mounted, and the lid 12 is removably mounted on the opened side. At this time, a through hole is formed in the lid 12 so that a shaft 30 to be described later can be fitted.

The rotating body 20 is configured to be rotatable in the above-described working space 11 as shown in Figs. 6 to 8. Thus, it is preferable that the rotating body 20 is formed in a shape that can be stably rotated without causing interference with other components or parts while rotating, for example, in the form of a disk.

The rotating body 20 also has an operation hole 21 formed at the center thereof as shown in Figs. 6 to 8. The operation hole 21 is provided with a shaft 30 so that it can rotate together with the rotating body 20 or only the shaft 30 can be rotated.

In the preferred embodiment of the present invention, as shown in Fig. 6, at least one of the rims is protruded outward so that the operating hole 21 is in contact with the lock pin 40 mounted on the shaft 30 It is preferable to form a wide section. This is to make the rotating body 20 and the shaft 30 rotate together by the frictional force of the lock pin 40 while contacting the operating hole 21 so that the frictional force can be increased by widening the frictional area.

The shaft 30 is constituted by a rotating portion 31 protruding out of the main body 10 and a friction portion 32 constituting the main body 10 as shown in Figs. 5 to 8. At this time, the shaft 30 is rotatably mounted to the main body 10, and is illustrated as an example in which the shaft 30 is supported by the through hole formed in the lid 12 as an example. However, the shaft 30 may be mounted on the main body 10 so as to be rotatably supported by the rotation itself.

At this time, since the gear 50 to be described later is mounted on the rotating portion 31, the gear 50 can be fitted and rotated together. In the figure, the rotating part 31 is formed into a square pillar shape, and the gear 50 is fitted and fixed so as to be rotatable together. However, a method of fixing the gear using a polygonal column, an ellipse, May be used.

Particularly, as shown in Fig. 6 and Fig. 7, at least two operating grooves 33 are formed on the outer periphery of the friction portion 32. As shown in Fig. At this time, the operating groove 33 is formed so as to be deepened in the direction when the shaft 30 rotates in either direction, that is, in the counterclockwise direction with respect to the center of the friction portion 32 (33) are formed.

8 (a)), the operating groove 30 is formed so as to receive the entire depth of the lock pin 40, which will be described later, The lock pin 40 is inserted between the rotating body 20 and the shaft 30 as the lock pin 40 moves to the lower side as shown in Fig. 8 (b) .

These operating grooves 30 form at least two, which can be selected in the range of 2 to 10 to provide sufficient frictional force depending on the diameter of the shaft 3. [ Of course, it does not matter if the number is more than that.

Further, the operating grooves 30 are formed at predetermined intervals on the outer circumference of the friction portion 32, but are preferably formed at equal intervals. This is to allow the frictional force generated by the rotational force of the shaft 30 to be transmitted to the rotating body 20 through the uniformly-moving operation hole 21, thereby stably supporting the rotation.

As shown in Figs. 6 to 8, the lock pins 40 are provided in the above-described operation grooves 33, respectively. The lock pin 40 is formed in a roller or ball shape so that when the shaft 30 rotates as shown in FIG. 8, the rotating body 20 and the shaft 30 move together in the operating groove 33 Or only the shaft 30 is rotated. Such operation will be described later.

The gear 50 is fixed to the above-described rotating portion 31 as shown in Figs. 5 to 8. In this case, the gear 50 is manufactured by a conventional technique and rotates the shaft 30 as it is rotated through a linear motion such as a rack-pinion or a rotary motion with other gears.

The damping action of the rotary damper according to the present invention will now be described with reference to FIG.

First, as shown in Fig. 8 (a), when the shaft 30 rotates in the clockwise direction, the friction portion 32 rotates together with it. At this time, since the lock pin 40 moves toward the inside of the operating groove 33, that is, the depth is deeper, no friction occurs between the rotating body 20 and the friction portion 32, and only the shaft 30 rotates.

8 (b), when the shaft 30 rotates in the counterclockwise direction, the friction portion 32 rotates together with the rotation of the shaft 30. Accordingly, the lock pin 40 is moved outwardly of the operating groove 33 Move to the lower depth. As a result, a friction force is generated between the rotating body 20 and the friction portion 32 while the lock pin 40 is caught between the inner surface of the operating hole 21 and the lower operating groove 33, And the shaft 30 rotate together. Thus, the rotating body 20 damps while rotating in the working fluid.

As described above, according to the present invention, when the shaft rotates, the rock pin is protruded or retracted according to the rotation direction of the shaft, and the damping action can be obtained only when the rock pin is rotated in either direction along the rotation direction.

Therefore, the damping device of the slide type according to the first embodiment can quickly and accurately obtain the damping action while reducing the overall size by using a rotary damper of a small size.

[Embodiment 2] according to the present invention has the same structure as that of [Embodiment 1], but as compared with [Embodiment 1], as shown in Fig. 9, the structure of the rotary damper (D) There is a difference in that grooves 21a are additionally formed. Therefore, the same reference numerals as in [Embodiment 1] are used for the same reference numerals, and a detailed description thereof will be omitted, and only the additional configuration will be described here.

[Embodiment 2] In the embodiment 2, as shown in Fig. 9, the fixing groove 21a is further added in the above-mentioned operation hole 21. [ When the lock pin 40 is in a position sandwiched between the operating hole 21 and the friction portion 32 as shown in Figs. 8 (b) and 9 By forming the lock pin 40 on the inner surface of the operating hole 21 in contact with the pin 40 so that the lock pin 40 engages with the stopper to engage the rotating body 20 and the shaft 30 more firmly It is.

[Embodiment 3] According to the present invention, as shown in FIG. 10, a friction protrusion 22 is further provided on the rotating body 20 in the structure of the rotary damper D as compared with [Embodiment 2] . Therefore, the same reference numerals as in [Embodiment 2] are used for the same reference numerals, and a detailed description thereof will be omitted, and only additional configurations will be described here.

[Example 3] is a case in which a ridge 22 is formed on the rotating body 20 as shown in Fig. The friction protrusions 22 are configured to friction with the working fluid when the rotating body 20 rotates in the working space 11 filled with the working fluid so as to increase the damping force. That is, since the friction protrusions 22 prevent the rotating body 20 from rotating easily due to the working fluid, more force is required to rotate the rotating body 20 accordingly.

In the preferred embodiment of the present invention, since the damping force can be adjusted according to the number of the friction protrusions 22, it is possible to manufacture a rotary damper having different damping forces even if a rotary damper of the same size is used.

Since the friction protrusions 22 can be formed on at least one of both surfaces of the rotating body 20, the friction protrusions 22 can be formed on one or both surfaces depending on the strength of the damping force It will be readily apparent to those skilled in the art.

As described above, according to the present invention, since the rotational resistance of the rotating body rotating in the working fluid can be adjusted through the friction protrusions, it is possible to adjust the damping force as well as the damping force of the same size, Can be used.
