Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a floor suction device for a vacuum cleaner having a dust collector such as a brush or a rubber lip.

Conventional technology In a conventional floor suction device, a hook-shaped locking portion is formed on both inner ends of the suction device body, and a positioning rib is formed on the top surface, and the mounting portion of the dust collector is attached to this locking portion. There was something that was caught between the part and the rib (for example,
53-149463).

Problems to be Solved by the Invention However, with this device, the main body of the suction device had to be bent once in order to lock the attachment portion of the dust collector to the hook-shaped locking portion, making the operation difficult. In order to solve this problem, it is possible to reduce the locking distance of the locking portion, but this is not practical because it is easy to disengage. Another solution is to form the attachment part of the dust collector with an elastic material as in the above-mentioned Japanese Utility Model Publication No. 53-149463, but if the dust collector is made of a rubber lip, its shape retention will deteriorate. , problems arise in terms of dust collection efficiency.

The present invention solves these conventional problems and allows the dust collector to be attached easily and reliably.

Means for Solving the Problems In order to solve these conventional problems, the present invention has hook-shaped locking parts on both inner ends of the main body of the floor suction device, and positioning ribs on the top surface. The attachment part of the dust collector is clamped and attached between the locking part and the positioning rib, and a small hole is formed in the upper surface of the locking part of the suction tool main body.

Effects According to the above configuration of the present invention, the flexibility of the suction tool body near the locking portion is increased due to the presence of the small hole. Therefore, the attachment part of the dust collector can be easily locked to the locking part, and even if the locking allowance is large, the locking work is not much different, and the dust collector can be more securely attached. Further, the mounting portion may be a rigid body, and even if a rubber lip is used as the dust collector, its shape will be reliably maintained.

Embodiments Hereinafter, embodiments will be described based on the accompanying drawings.

In the figure, reference numeral 1 denotes a main body of a floor suction tool, and a sled-shaped flange portion 2 is formed at the front and rear. Reference numeral 3 denotes a pipe for connecting to a vacuum cleaner, which is rotatably held in place by fastening the stop plate 4 and the main body 1 with screws 5. 6 is a retaining ring to prevent the pipe 3 from coming off; 7 is a dust collector made of rubber, etc.; protrudes to. and,
The dust collector 7 is attached to the main body 1 by hook-shaped locking portions 9 and positioning ribs 10 integrally formed at both ends of the main body 1. Reference numeral 11 denotes small holes formed at both ends of the main body 1, which are used to adjust the deflection of the main body 1 when the dust collector 7 is attached.

In the above configuration, the dust collector 7 can be attached by bringing the dust collector 7 into contact with the lower part of the locking part 9 and then pushing it in. That is, the thin plate 8 of the dust collector 7 advances along the inclination of the locking part 9 due to the deflection of the main body 1, and is finally locked to the upper end of the locking part 9, and at the same time comes into contact with the positioning rib 10. Installation is complete. In other words, the thin plate 8 of the dust collector 7 is accommodated between the locking portion 9 and the rib 10. Furthermore, ribs 11' and 12 for preventing dislodgement are formed before and after the locking portion 9 and the positioning rib 10. When the dust collector 7 is attached to the locking part 9, the small hole 11 has the effect of making the main body 1 in the vicinity of the locking part 9 easier to bend, thereby simplifying the installation. That is, by forming the small hole 11, the side portion of the main body 1 in the vicinity of the small hole 11 becomes substantially smaller in front and back width, making it easier to bend.

Of course, the amount of deflection can be adjusted depending on the size of the small hole 11, so that the dust collector 7 can be easily inserted and installed reliably.

Effects of the Invention As described above, according to the present invention, the dust collector can be easily attached with a simple structure, and moreover, it can be attached reliably without being unnecessarily removed. It also has great practical value, as it allows the dust collector to perform its functions to the fullest no matter what type of dust collector it is.
