Description

Structure of vacuum cleaner wheel {a structure of vacuum cleaner wheel}

The present invention relates to a wheel structure for a vacuum cleaner, and more particularly to a wheel structure for a vacuum cleaner having a spherical wheel so that the vacuum cleaner can move freely from side to side.

As shown in Figure 4, a conventional vacuum cleaner, a large wheel 101 to the body attached to both sides of the rear and the front to change the wheel (not shown) to be able to move every corner of the house.

However, such a vacuum cleaner 100 was to use a wheel that can be changed only in the front direction and the wheel 101 that can be moved back and forth only in the rear. Therefore, it was not easy for the user to move the vacuum cleaner 100 in a direction different from the direction of movement of the rear wheel.

In addition, even if the vacuum cleaner 100 is moved in the direction in which the user wants to move, the rear wheels are initially dragged instead of rolling, which causes a problem of scratching the floor covering in the house.

In particular, this problem appeared more seriously when a paper sheet (folk sheet) was laid in the room, causing economic waste to be replaced by a vinyl sheet.

In addition, in the conventional vacuum cleaner 100, since the rear wheel 101 only moves back and forth, it was impossible to move by-pass by itself except when the user was forced to move when caught by another obstacle. Therefore, when a user inadvertently drags the vacuum cleaner 100, a problem occurs that the hose 102 of the vacuum cleaner 100 is broken due to a force.

The present invention is to solve the problems as described above, it is the purpose to provide a vacuum cleaner wheel structure to freely move forward and backward, left and right by using a spherical wheel, even from the stationary state to the reverse conversion.

The present invention vacuum cleaner wheel structure for achieving the above object, the bone and bolt hole for fastening is formed on the outside and the hemispherical space is formed therein, a plurality of grooves are formed, the lower body is formed with a jaw, A bearing coupled to the groove, a spherical wheel inserted into the space, a hole in which a center jaw is formed, and a bolt hole is formed outside the body to be fixed by a bolt to the bottom of the body, the body and the fixing plate Characterized in that formed by a ball bearing fitted to the formed jaw.

Hereinafter, it will be described in detail through an exemplary drawing according to an embodiment of the present invention.

1 is an exploded perspective view illustrating a wheel structure for a vacuum cleaner according to an embodiment of the present invention, the bearing 20 having a hemispherical space 15 formed therein, a bearing 20, and a spherical wheel 30. After the ball bearings 40 are sequentially inserted, the fixing plate 50 is positioned at the lowermost end and fastened by the bolts 60 so that the bearings 20, the wheels 30, and the ball bearings 40 are fixed so as not to be separated. .

The outer side of the body 10, the bone 11 is formed to facilitate the coupling to the vacuum cleaner body (not shown), the bolt hole 12 for fastening with the fixing plate 50 is formed.

A plurality of grooves 14 are formed in the body 10 so that the spherical bearing 20 is installed in the groove 14, and the ball bearing 40 to be installed on the bottom of the body 10 may be attached and fixed. The jaw 13 is formed so that.

A spherical wheel 30 is inserted into the space 15 into which the ball bearing 40 is inserted, and smoothly and freely moves back and forth, left and right by contacting the bearing 20 inserted into the groove 14 of the body 10.

The ball bearing 40 is coupled to the jaw 13 formed in the body 10 so that the wheel 30 does not escape downward.

The fixing plate 50 which is fastened by the body 10 and the bolt 60 is formed with several bolt holes 53 for fastening the bolt 60, and the wheel 30 protrudes downward. 51 is formed, and the hole 51 is formed with a jaw 52 that can support and fix the ball bearing 40.

2 is a partial cutaway perspective view according to an embodiment of the present invention, the wheel 30 is inserted into the body 10 is embedded in the bearing 20 and the ball bearing 40 inserted into the groove 14 In point contact with the ball 41.

Therefore, the wheel 30 has an advantage that the area in contact with the outside is very small, the shape of the wheel 30 is spherical, there is a feature that can move freely back and forth and left and right.

3 is a partial cross-sectional view according to an embodiment of the present invention, the body 10 is coupled to the vacuum cleaner 100 using a bolt coupling. At this time, the coupling method may use other fastening means, such as rivet coupling, it may be used an adhesive or the like.

The wheel 30 provided in the combined body 10 always serves as a wheel to protrude downward from a certain portion.

It is preferable that the ball bearing 40 for fixing the wheel 30 so as not to be separated outward is coupled to a lower direction than the center of the wheel 30.

In addition, the wheel 30 is preferably made of a lightweight material (for example, thermosetting plastic, etc.) to reduce the noise and weight, the bearing 20 and the ball 41 is friction with the wheel 30 It is preferable to use a metal material so that it can be reduced.

According to the wheel structure for the vacuum cleaner of the present invention as described above, it is possible to move in all directions in the stationary state, there is an effect that the movement of the vacuum cleaner is easy.
