Abstract

PURPOSE:To make an extension tube whose diameter is a little different, as well useable and to prevent the collapse, etc., of the extension tube by structuring an extension tube connecting body with a holding body of a screw tightening structure having a slit, and a fitting body engaged to a cleaner main body. CONSTITUTION:An extension tube fitting body 4 and an extension tube holding body 6 are assembled by fitting the turning shaft 9 of the extension tube holding body 6 to the receiving hole 10 of the extension tube fitting body 4, inserting the extension tube holding body 6 into an extension tube 3 and tightening it with a screw to a screw fitting part 11 in an optimum position. Since the claw part 8 of the extension tube fitting body 4 is a tapered shape, the extension tube 3 can be held together by the claw part with an inserting/holding side face rib 12. On the extension tube holding body 6, a slit 13 being shorter than its vertical dimension is provided and it is a screwed structure, therefore, the extension tube whose diameter is a little different can also be used. Also, even if excessive force is applied to the extension tube fitting body 4, the stopper part 14 of the extension tube fitting body 4 is brought into contact with the continuous annular part 15 of the extension tube holding body 6, and it does not occur that the force is exerted directly on the extension tube 3.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a vacuum cleaner in which a hose, an extension pipe, and a floor suction port are housed in the vacuum cleaner body while being connected to the vacuum cleaner body. .

[Conventional technology]

In the conventional technology, as in Japanese Patent Application Laid-Open No. 63-51821, the connecting body was composed of one piece.

[Problem to be solved by the invention]

The above conventional technology is effective in terms of cost because the connecting body is made up of one part, but if extensions with slightly different diameters are used, separate connecting bodies (with different diameters) must be newly installed. There was a problem.

In addition, since the connecting body is not mechanically fixed to the extension tube, the position of the connecting body moves when raised and retracted from the extension tube, resulting in the problem that the connecting body cannot be fixed at an optimal position on the extension tube. There was a point.

Furthermore, if unnecessary force is applied when the connecting body is raised to a state where it can be engaged with the vacuum cleaner main body, the stopper portion of the connecting body directly applies force to the extension tube, which may cause the extension tube to collapse.

An object of the present invention is to provide a connecting body that can be used and fixed to extension pipes of slightly different diameters and has excellent strength.

[Means to solve the problem]

The above purpose is to form a slit part in a part of the extension tube holder, and fix it to the extension tube by tightening the screw, and the stopper part of the extension tube fitting body that engages with the vacuum cleaner body is fixed to the extension tube holder. By making the structure contact the continuous annular part,
Being a distant relative.

[Effect]

Even if an extension tube with a slightly different diameter is inserted into the extension tube holder slit, it is screwed to the screw attachment sections provided on both sides of the slit. It can prevent movement and wobbling.

In addition, even if an unreasonable force is applied to the extension tube fitting that is engaged with the vacuum cleaner body, the stopper part of the extension tube fitting comes into contact with the continuous annular part of the extension tube holding part, and the force is not directly applied to the extension tube. do not have.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. Third
The figure shows the main parts of this embodiment in an installed state.

1 is a vacuum cleaner body, 3 is an extension tube, 4 is an extension tube fitting body which is a component of the connection body, 6 is an extension tube holder which is one of the components of the connection body, 7 is a body receiving part, and 8 is a claw part. shows.

Next, the configuration and operation will be explained. First, when assembling the extension tube fitting body 4 and the extension tube holder 6, the rotation shaft 9 of the extension tube holder 6 and the bulge 10 formed on the extension tube fitting body 4 are fitted together. When attaching to the extension tube 3, insert the extension tube holder 6 and tighten it with a screw to the screw attachment part 6 at the optimum position.

The claw portion 8 integrally formed on the extension tube fitting body 4 is formed in a tapered shape so as to have <y>x as described in the sixth section. Also, when comparing parts A and B of the extension tube fitting body 4, the shape is narrowed by the dimension z-y, so when holding the extension tube as shown in Fig. 4, the surface of the extension tube 3 Since the claws have a tapered shape, the claws 8 can be firmly held while making contact with the clamping side ribs 12.
You can hold the extension tube 3 together with this. When storing accessories by attaching them to the main body, even if the claw part 8 integrally molded on the extension tube fitting body 4 is inserted into the main body receiving part 7, since the claw part 8 is formed in a tapered shape, the main body receiving part 7 When inserted into
Since the tapered part is inserted into the insertion surface of the main body receiving part 7 while opening outward, wobbling is reduced and fixation becomes more reliable. Furthermore, the extension tube holder 6 is provided with a slit 13 that is shorter than the vertical dimension of the extension tube holder and has a screw-fastened structure, so the extension tube fitting body 4 and the extension tube holder 6 are integrated. Although it has one more component than the previous model, it does not move up and down due to reaction when a strong impact is applied, so it can always be inserted and stored in the main body receiving part 7 at the same position.

Moreover, even if an unreasonable force is applied to the extension tube fitting body 4 that is engaged with the vacuum cleaner main body 1, the stopper portion 14 of the extension tube fitting body 4
is in contact with the continuous annular portion 15 of the extension tube holder 6 and does not directly apply force to the extension tube 3.

The screw attachment part 11 is connected to the extension tube 3 while the extension tube fitting body 4 is being cleaned.
Since it is held between the screws and the screw mounting portion 11 is covered, the design does not spoil the appearance.

〔Effect of the invention〕

According to the present invention, by providing the extension tube holder with the slit portion, even if extension tubes having slightly different diameters are used, one connecting body can cover them.

Further, even if an unreasonable force is applied to the extension tube fitting body engaged with the vacuum cleaner main body, the stopper portion of the extension tube fitting body contacts the continuous annular portion of the extension tube holding portion, and no force is directly exerted on the extension tube.
