On the other hand, the dust collector coupling device 100 is to be airtight with the cover member 212 of the cleaner body 210 by lifting the dust collector (220). This is in accordance with the contents of the dust collector coupling device described later.

With reference to Figures 3 to 6, it describes a dust collecting coupling device 100 according to an embodiment of the present invention.

First, cradles 221 are formed on both side surfaces of the dust collecting container 220. At this time, the cradle 221, as shown in Figure 2, may be a plate-shaped member coupled to the upper side of the outer surface of the dust collector 220, the cradle 221 is separable to the engaging portion 40 to be described later To be combined.

Dust collector coupling device 100 according to an embodiment of the present invention is provided side by side on both sides of the cleaner body 210, a pair of pillar portion 10 is formed to face the long hole 11 in the vertical direction And, a pair of extension pieces 22 are formed side by side at both ends of the horizontal bar 21, the end portion of the extension piece 22 is restrained by the long hole 11, the handle portion 20 is elevated And, one end 31 is rotatably coupled to the pillar portion 10, the other end 32 is rotatably coupled to the extension piece 22, the extension when the horizontal bar 21 is lowered The end portion 23 of the piece 22 is protruded from the opposite side of the link portion 30 and the extension piece 22 to ride up the long hole 11, the foreign matter discharged from the cleaner body The containment includes a catching part 40 to which the holder 221 formed on the dust collecting container 220 is detachably coupled.

The pair of pillar portions 10 have planes facing each other, and the long holes 11 in the vertical direction are formed at the same height. In addition, the through hole 12 in which the one end 31 of the link portion 30 is hinged is formed in the vertical lower direction of the long hole 11.

The handle part 20 includes a horizontal bar 21 having a length corresponding to the spaced distance between the two pillar parts 10, and an extension piece 22 extending side by side from the horizontal bar 21. Horizontal bar 21 is a portion that is held by the user generally has the shape of a rod, it may be formed in a gentle bend to be comfortable to hold. In addition, the extension pieces 22 formed at both ends of the horizontal bar 21 are formed so that the planes face each other, the middle portion is gentle so that the horizontal bar 21 is in a position comfortable for the user when connected to the long hole. It may be a curved shape.

At this time, in forming the handle portion 20, both ends of the elongated rod may be bent in parallel to each other, and the ends of the bent portion may be compressed into a vertical flat plate to form an extension piece 22.

The extension piece 22 is constrained by the end portion 23 of the long hole 11 formed in the pillar portion 10, is elevated on the inner circumferential surface of the long hole 11, and is configured to be rotatable in the long hole 11. To this end, general coupling members such as bolts, washers, and nuts are used to hinge each end 11 of each long hole 11 and each extension piece 22. Furthermore, more preferably, the bearing may be further coupled to reduce wear when lifting up and down in the long hole.

On the other hand, the link portion 30 is one end 31 is hinged to the through hole 12 formed in the pillar portion 10, the other end 32 is hinged to the extension piece (22). At this time, the other end 32 of the link portion 30 is hinged at an intermediate portion closer to the horizontal bar 21 than the position of the end portion 23 of the extension piece 22 coupled with the long hole 11. At this time, the hinge coupling of both ends of the link portion 30 is usually made through well-known bolts, nuts, washers, bearings and the like.

As a result, when the horizontal bar 21 descends, the end 23 of the extension piece 22 is raised by the long hole 11, and when the horizontal bar 21 is raised, the end of the extension piece 22 is raised. Part 23 is coupled down linking the long hole (11).

On the other hand, the locking portion 40 is protruding from the opposite surface of the extension piece 22, it is detachably coupled to the cradle 221 of the dust collecting container (220). Specifically, the locking portion may be formed of a protrusion that is coupled to protrude from the inside of the end portion of the extension coupled to the long hole, whereby the cradle may be formed as a concave groove to the top corresponding to the protrusion. At this time, the groove and the projection may be formed by changing the position.

Specifically, as shown in Figure 4, the engaging portion 40 is a mounting groove 42 is formed on the outer circumferential surface, the cylindrical projection is rotatably coupled at the end 23 of the extension piece 22 41.

In addition, the holder 221 is configured to include a mounting piece 221a which is fixed to be spaced apart from the outer wall surface 224 of the dust collecting container 220, the mounting piece 221a on the mounting groove 42 Raised horizontal piece (221b), is formed concave from the inner side of the horizontal piece (221b) to the upper portion perpendicular to the end of the insertion groove (221c) and the insertion groove (221c) is fixed to the mounting groove 42 A stopper piece 221d may be formed to prevent movement of the cylindrical protrusion 41.

The cradle 221 is made of a bracket including the cradle 221a, both sides are fixed to the dust collecting container 220, the mounting piece 221a is spaced apart from the outer wall surface 224 of the dust collecting container 220. The space between the outer circumferential surface of the dust collector and the mounting piece is a space into which the inner side of the cylindrical protrusion is inserted.

A portion of the lower side of the mounting piece 221a is cut off to form a horizontal piece 221b, an insertion groove 221c, and a stopper piece 221d.

Since the cylindrical protrusion 41 is constrained by the long hole, as shown in the figure, the cylindrical protrusion 41 can move only in the vertical direction. When the dust collecting container 220 placed on the ground is pushed into the lower space of the cleaner body, the lower surface of the horizontal piece 221b moves on the mounting groove 42 formed in the cylindrical protrusion 41. Thereafter, when the dust collecting container 220 is pushed further, since the mounting groove 42 of the cylindrical protrusion 41 is caught by the stopper piece 221d formed vertically, further advance is prevented. Thereafter, when the user manipulates the handle part and the cylindrical protrusion 41 is raised, the mounting groove 42 of the cylindrical protrusion 41 is moved to the insertion groove 221c of the mounting piece 221a, thereby leaving the mounting groove 42. It is not possible to raise the cradle 221. That is, the cylindrical protrusion 41 is inserted into the insertion groove 221c, so that the dust collecting container 220 can be in close contact with the cover member of the cleaner body.

5 to 7, the coupling relationship and the operation relationship of the dust collector coupling device will be described.

5 is a state in which the handle portion 20 is lifted, and the dust collecting container can be separated from the cleaner body to the outside.

As the horizontal bar is lifted based on the drawing, the link part 30 is rotated to the right, and the end 23 of the extension piece 22 is brought down to the maximum by riding the long hole 11. Therefore, since the position of the locking portion 40 provided at the end 23 of the extension piece 22 is lowered, and the cylindrical projection is moved under the insertion groove, the dust collecting container can be pulled out of the cleaner body. Will be.

On the other hand, Figure 6 is a state in which the handle portion 20 is lowered, the dust collector is raised and in close contact with the cover of the cleaner body.

Based on the drawings, as the horizontal bar is lowered, the link unit 30 is rotated counterclockwise with respect to the rotation axis of the one end 31. Accordingly, the end portion 23 of the extension piece 22 is raised to the upper part of the long hole 11, and as a result, the cylindrical projection provided at the end of the extension piece 22 is raised with the insertion groove being fitted to raise the dust collecting cylinder. .

At this time, the horizontal bar 21 is blocked by the stopper portion (see (c) of FIG. 7) coupled to the lower end of the horizontal bar 21 while descending, and the link portion 30 during the lowering of the horizontal bar. The rotating shaft formed at the other end 32 of the) is configured to pass through the virtual connecting line (L1) of the rotating shaft of the long hole 11 and the end portion 31 of the link portion (30).

Specifically, the rotation axis center A to which the link portion 30 and the extension piece 22 are connected includes the hinge axis center B and the link portion () of the long hole 11 and the end portion 23 of the extension piece 22. It is positioned to be further biased to the left through the virtual connecting line (L1) connecting the 30 and the hinge axis center (C) of the column (10).

In this case, when the load of the dust collecting container in which foreign matter is collected acts vertically downward to the end 23 of the extension piece 22, this load is such that the link part 30 shifted to the left is further rotated counterclockwise. Thus, the extension piece 22 acts to rotate clockwise with its end 23 coupled to the long hole 11 as the axis of rotation. At this time, the horizontal bar 21 integral with the extension piece 22 is no longer able to rotate while contacting the stopper portion 233, as shown in FIG. That is, the load of the dust collecting container is transmitted to the link portion 30 and the extension piece 22, and finally the handle portion 20 is supported while being caught by the stopper portion 233.

At this time, the stopper portion 233 may be an end frame provided in the above-described moving bottom portion, although not shown, is provided in the pillar portion to limit the rotation angle of the handle portion, when rotating over a certain range of the handle portion It can be made of a structure that is attached to any part.

As a result, the handle lowered by the load of the dust collecting container does not rise regardless of the user's intention, so that the combination of the dust collecting container and the cover member can be maintained.

Referring to FIG. 3 again, the end portion 23 of the extension piece 22 and one end 31 of the link portion 30 may be connected to the elastic member 50. The elastic member 50 may be a tension spring 51 as shown, or may be replaced with a rubber band to provide other elasticity.

The elastic member 50 is continuously constrained by the long hole 11, the end portion 23 of the extension piece 22 is elevated to continuously give a force to lower.

In this case, when the link portion 30 is further rotated clockwise through the virtual connecting line L1 as described above, the end portion 23 of the extension piece 22 is pulled to one end of the link portion 30. Therefore, the handle portion 20 can be prevented from rising arbitrarily. That is, the coupling between the dust collecting container 220 and the cover member of the cleaner body 210 is maintained. In particular, when the extension of the handle portion 20 is made long, the inertia of the horizontal bar is increased, thereby helping to eliminate the fear of the handle portion is raised by the impact force generated when riding over a small bump during the process of moving the cleaner body Becomes

The operation of the present invention will be described with reference to FIG.

7 (a) is a state in which the handle part 20 is raised, and the dust collecting container 220 is in a state of being lowered to the maximum. At this time, the moving means 223 provided in the lower part of the dust collecting container 220 is in a state where the user can easily move the dust collecting container on the ground. Therefore, the user pushes the dust collecting container 220 into the lower space of the cleaner body, thereby easily positioning the cylindrical protrusion provided at the end of the extension piece under the insertion groove provided in the holder of the dust collecting container.

On the other hand, Figure 7 (b) is a state in which the handle portion 20 is lowered to some extent, at this time, the link portion 30 is rotated perpendicular to the ground. At this time, the end portion 23 of the extension piece 22 is raised to the maximum along the long hole 11, and accordingly, the dust collecting container 220 is also raised to the maximum.

On the other hand, Figure 7 (c) is in a state of further lowering the handle portion 20 in Figure 7 (b). At this time, the link portion 30 is further rotated in the counterclockwise direction, the height of the end portion 23 and the dust collecting container 220 of the extension piece 22 is in a somewhat lowered state than in FIG. This height difference is the compression range allowed by the sealing member described above, or the elastic range of the hopper and the cover member does not cause any problems in the airtight inside the dust collector. At this time, as described above, the load of the dust collecting container 220 through the link portion 30, the handle portion 20, the handle portion 20 with the end portion 23 of the extension piece 22 as the center of rotation To rotate clockwise. Since the end portion of the handle portion 20 is in contact with the stopper portion 233, it can no longer rotate, and thus, the coupling between the dust collecting container and the cover member is maintained. In addition, the moving means of the dust collecting container is in a state away from the ground.

The present invention is such that a detachable coupling between the heavy dust collector and the cover member is made through the link connection. At this time, as the extension is formed to extend the length it is possible to further reduce the force required when raising or lowering the dust collector by the principle of the lever.
