Description

[Detailed description of the invention] This invention relates to an improvement of a floor brush used in a vacuum cleaner.

An embodiment of this invention will be described below.

Reference numeral 1 denotes a floor brush main body, which has a suction port 2 in the center of its lower surface, a lower case 4 and an upper case 5, each having suction grooves 3, 3 having one end communicating with the suction port and the other end extending to both sides. It is made up of.

Reference numeral 6 denotes a horizontally long brush holding groove formed in front of the suction port 2, and a brush attachment hole 7 is provided in the upper wall of the groove.

8, short convex pins 9 are formed at a predetermined interval in the front row of the lower surface, and long convex pins 10 are formed in the rear row to be located between the convex pins 9, and a part of the convex pins is thin on the top surface. This is a horizontally elongated brush part made of soft rubber and provided with a stop part 11.

This brush part 8 is inserted into the brush holding groove 6, and the stop part 1
1 is inserted and supported in the brush attachment hole 7 by utilizing its elasticity.

Reference numeral 12 denotes a horizontally elongated brush holding groove formed behind the suction port 2, and a brush mounting hole 13 is formed in the upper wall of the groove.

Reference numeral 14 denotes a brush part having a plurality of brushes 15 at its lower part and a stop part 17 at its upper part in which stop pieces 16 having a sloped surface at a predetermined interval and an apex thereof are arranged alternately on the left and right. be.

This brush part 14 is inserted into the brush holding groove 12, and each stop part 17 utilizes its elasticity to fit into the brush mounting hole 12.
3, each of which is supported in a vertically movable manner.

Reference numeral 18.18 is a coil spring provided between the brush portion 14 and the earthen wall of the brush holding groove 12, and causes the brush 15 to protrude downward from the lower surface of the floor brush body 1.

A connecting pipe 19 has one end communicating with the suction port 2, and is held between the upper and lower cases 5 and 4.

20 is a roller provided on both ends of the bottom front of the floor brush body 1, and 21 is a shock absorbing member provided on the side surface of the floor brush body 1.

This invention is constructed as described above, and the floor brush body 1
When the brush part 14 is inserted into the retaining groove 12 formed on the lower surface via the coil spring 18, the stop pieces 16 of the many stop parts 17 formed on the upper part of the brush part 14 are moved inwardly by their inclined surfaces. While moving, the brush part 14 passes through the brush mounting hole 13 provided in the holding groove 12, and the brush part 14 is held in a vertically movable manner.

At this time, since the retaining pieces 16 formed on the retaining portion 17 face alternately in the left and right directions, they will not easily come off even if twisted in one direction.

In this way, in this invention, the stop part is integrated into the brush part, so it is easy and simple to attach it to the floor brush body, and when removing it from the main body, all you have to do is move the stop part inward and press it. This has the effect of facilitating work during service.

It also has the advantage that the brush portion can be moved up and down favorably.
