Hereinafter, a vent device of a button type according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 and 2 show a vent device of a button type for a vehicle roof.

1 and 2, the vent device is provided with a rotor 10 having a cover 11 (see FIG. 5) inside an outer housing 20 fixed to a vehicle roof (not shown). The inner housing 30 is provided between the rotor 20 and the rotor 10. 1 is a vent device closed state, when the inner housing 30 is pushed up, the rotor 10 is lifted upwards, and the vent device is opened as shown in FIG. 2.

3 to 5, each component of the vent device will be described.

As shown in FIG. 3, the outer housing 20 has a structure in which a plurality of guides 22 having vertical lengths are provided at predetermined intervals on an inner surface of a hollow cylindrical body 21 having a vertical opening. Single-layer portions 22a, 22b, and 22c are formed on the upper end of the guide 22. The tomographic part has a structure in which the lower layer 22a and the upper layer 22c are inclined in one direction (having a slope), respectively, and have a structure in which the jaw 22b is formed vertically, and has a shape of a roughly saw blade. In this embodiment, the monolayer has two layers (one tuck), but may have three layers (two tuck). On the other hand, a stopper 24 having ribs 24a and 24c and a hill 24b is provided radially inward with respect to the guide 22 at the lower end of the guide 22 (see FIG. 7).

As shown in FIG. 4, the inner housing 30 is installed inside the outer housing 20, and like the outer housing body 21, the body 31 has a cylindrical structure in which the upper and lower sides are open. The upper end of the inner housing body 31 is formed with a sawtooth-shaped teeth 32 cutting along the circumference, the outer surface is the circumference of the protrusions 33 of the same number (or even double) as the guide 22 Formed along the direction. The protrusions 33 are locked by the stopper 24 (refer to FIG. 8) (but the protrusions are not fitted to the groove portion between the guide and the guide), so that the downward movement of the inner housing 30 is prevented. Limited.

As shown in FIG. 5, the rotor 10 is provided with a cover 11 covering the upper portion of the outer housing 20 on the hollow cylindrical body 13 installed inside the inner housing 30, and the cover 11. The bottom surface of the edge portion has a structure in which a plurality of riders 14 protrude. The upper part of the body 13 is removed while leaving only the connection part 12 for supporting the cover 11, and the remaining space constitutes the ventilation hole 15. On the other hand, the rider 14 has the shape of a chisel having a lower end edge in the radial direction.

6 to 8 will be described in detail with respect to the coupling and operation relationship between the main components of the vent device. 6 and 8 illustrate a state in which the vent device is opened, that is, a state in which the rotor 10 is lifted by the inner housing 30.

The rider 14 is mounted on both the tomographic part of the outer housing and the teeth 32 of the inner housing so that the rotor 10 is lifted upward when the inner housing 30 is pushed up (see FIGS. 6 and 7). Accordingly, the outside air can be introduced into the room through the vent hole 15 of the rotor 10. In the vent device closed state, the inner housing 30 supports and interferes with the protrusion 33 by the stopper 24. The inner housing 30 is pushed upward to raise the protrusion 33 so that the protrusions of the stopper 24 are exposed to each other. Departing from 24a and 24c, the inner housing 30 is rotatable in the outer housing 20. Only when the hill 24b is pushed up from the low point where the inner housing 30 is supported by the stopper 24 to the predetermined height (that is, the lifted height enough to ride over the hill), only the vertical movement is possible. Rotational movement is limited.

On the other hand, the valley includes a main valley 24a and a sub valley 24c. The sub valley 24c is formed at a position higher than the main valley 24a. The main valley 24a approximately matches the line of the groove 23 between the guide and the guide, and the sub valley 24c approximately matches the line of the jaw 22b of the tomography. However, these are not completely matched with each other, but are slightly mismatched. Referring to FIG. 8, the valleys 24a and 24c are slightly shifted to the right than the groove 23 line or the tuck 22b line. This reason is mentioned later. On the other hand, the edge of the peak 24b is formed to be gentle or inclined. This is to allow the protrusions 33 of the inner housing 30 to be smoothly seated on the valleys 24a and 24c while rotating.

9A, 9B, and 9C, the rider 14 of the rotor 10, the tomography portion of the outer housing 20, and the tooth portion 32 of the inner housing 30 are symbolic figures, respectively. Expressed as The opening and closing structure of the button-type vent device will be described using the symbol figure.

First, the vent device opening process will be described with reference to FIGS. 10A to 10H.

10A is a view of the vent device closed state. The rider 14 is supported on the toothed portion 32 through the first groove portion 23-1 between the first guide 22-1 and the second guide 22-2. The inner housing 30 has a protrusion 33 seated on the main valley portion 24a of the stopper 24 to restrict movement in the downward direction and the left and right directions. It should be noted that the tip of the rider 14 is not seated in the valleys of the teeth 32 but lies on the slope between the peaks and valleys. This is because the tomographic part and the toothed part 32 are slightly offset from each other, and the main valley portion 24a and the groove part 23 of the stopper 24 are matched with each other.

In the state of FIG. 10A, when the inner housing 30 is pushed up, the rider 14 supported by the teeth 32 gradually moves upward (see FIG. 10B). At this time, since the rider 14 is fitted into the first groove 23-1, the horizontal movement of the rider 14 is limited, and the inner housing 30 has the protrusion 33 located at the main valley 24a interfering with the hill 24b. There is limited movement from side to side.

When the rider 14 moves upward and exits from the first groove 23-1 (FIG. 10B → FIG. 10C), the rider 14 moves on the slope of the teeth 32 by its own weight and moves to the right. (Ie, the rotor gains rotational force in the right direction) and falls. Then, when the rider 14 reaches the valley bottom of the teeth 32, the rider 14 pushes the teeth 32 so that the inner housing 30 also rotates in the right direction so as to fall down (see FIG. 10D). ). On the other hand, in order to move the rider 14 on the slope of the teeth 32 in the state of Figure 10c to provide a rotational force to the inner housing 30, at least the rider 14 from the first groove (23-1) Until the exit of the tooth 32, that is, the rotation of the inner housing 30 should be limited, the depth of the main valley 24a should be determined in consideration of this matter.

The rider 14, which falls while rotating in the right direction, rests on the lower layer 22a of the tomography portion (see FIG. 10E), slides along the slope of the lower layer 22a (see FIG. 10F), and then to the jaw 22b of the tomography portion. It stops moving. On the other hand, while the rider 14 slides the slopes of the lower layer 22a, the rider 14 drags the teeth 32 while pushing the teeth in the right direction (see FIGS. 10E to 10G), and the rider 14 has a jaw ( Even after stopping by the movement 22b), the inner housing 30 continues to fall while rotating to the right until the projection 33 is supported by the stopper 24 (see FIG. 10H).

10H is a view of the vent device in an open state, in which the protrusions 33 are seated on the sub valleys 24c of the stopper 24, where the tomographic portions and the toothed portions 32 are slightly offset from each other, and correspondingly, The sub valley 24c of the stopper 24 and the jaw 22b of the tomographic portion are slightly shifted from each other. And since the sub valley part 24c is arrange | positioned in the position higher than the main valley part 24a, the inner housing 30 will be located slightly upper than the state of FIG. 10A. Think of it as a push button, the button (corresponding to the inner housing) is pressed. On the other hand, the edge of the peak 24b is formed to be smooth or inclined, so that the protrusion 33 is easily seated into the valleys 24a and 24c.

A vent device closing process will be described with reference to FIGS. 11A through 11F.

11A is a view of the vent device open state (corresponding to FIG. 10H). When the inner housing 30 is pushed up, the rider 14 moves upwardly (see FIG. 11B), wherein the tip of the rider 14 is located on the slope of the teeth 32. When the upwardly moving rider 14 leaves the jaw 22b, the rider 14 slides on the slope of the teeth 32 and slides in the right direction (see FIG. 11C), and then the upper layer 22c Slip along the slope to the right (see FIGS. 11E and 11F). At this time, the rider 14 pulls the teeth 32 while pushing the teeth 32 in the right direction (see FIGS. 11D to 11E).

As shown in FIG. 11F (corresponding to FIG. 10A), the rider 14 slides along the upper layer 22c slope of the tomographic portion, and then is formed between the second guide 22-2 and the third guide 22-3. 2 Fall along the groove 23-2. That is, the rotor 10 is dropped and the vent device 15 is closed, the vent device is closed. The protrusion 33 of the inner housing 30 rests on the main valley 24a.

Meanwhile, as another embodiment, the protrusion of the inner housing may be fitted into the groove portion between the guide and the guide. In this case, the inner housing is not rotated only by moving up and down along the guide, and only the rotor is rotated to open and close the vent device. In addition, since the inner housing only moves in the vertical direction, a stopper for supporting the protrusion between the guide and the guide is sufficient, and the main and sub valleys are not required as in the previous embodiment. Of course, instead of using a guide or a stopper, it is sufficient that the inner housing is installed to be movable up and down in the outer housing by any method. However, in the vent device according to this embodiment, since the inner housing is not rotated, the rider moving the slope of the tomographic part is interfered by the inner housing (interference may occur in the situations of FIGS. 10E and 11D), and thus the opening and closing operation is performed. This may not be smooth. In this case, it is necessary to use the spring or otherwise to make the inner housing fall faster than the rider.
