Embodiment 1
The first embodiment will be described with reference to the drawings.
1 to 4, a suction attachment A for a vacuum cleaner (hereinafter referred to as “attachment A”) in the present embodiment is a part that sucks dust by being brought close to a surface to be cleaned, The suction pipe 1 is composed of an inner pipe 10 attached to the tip, and an outer pipe 9 to which the inner pipe 10 is attached. The inner pipe 10 enters and exits the outer pipe 9 so that the entire length of the attachment A is obtained. It is configured to be able to extend and contract.

(Outer pipe)
The outer pipe 9 is a member that holds the inner pipe 10 slidably inside. The outer pipe 9 is connected to a hose or an extension pipe connected to the cleaner body, and the inner pipe 10 is connected to the outer pipe 9. An expansion / contraction lock hole 9b for determining the position 10 and locking the sliding and a moderation hole 9c for notifying the storage state of the inner pipe 10 with a feeling of wearing are formed, and a storage holder 9f for attaching and storing the attachment A to the extension pipe 20 Is provided.

At the side of the connecting portion 9a of the outer pipe 9, when the attachment A is attached to the extension pipe 20, the cross-sectional shape of the outer pipe 9 is such that the positions of the attachment A and the extension pipe 20 are as close as possible to the extension pipe side. A D-cut portion 9g having a “D” shape is formed.
Further, since the D-cut portion 9g is formed on the end side of the D-cut portion 9g, when the connection portion 9a of the attachment A is inserted into the connection opening 25 of the extension tube 20 and connected, In order to prevent a gap from being generated as much as possible, seal ribs 9 h are formed in accordance with the inner shape of the extension pipe 20.

  The extension pipe 20 here is a pipe that guides sucked dust to the main body of the electric vacuum cleaner, and is connected to a hose connected to the electric vacuum cleaner and is configured to be stretchable. Moreover, although the outer pipe 9 has been described as being connected to the extension pipe 20, it may be directly connected to a hose.

  Next, an opening 9m into which the inner pipe 10 is inserted is formed at the end of the outer pipe 9 opposite to the connection portion 9a. Further, a moderation hole 9c and a telescopic lock hole 9b are formed on the opening 9m side of the outer pipe. The moderation hole 9c is located between the telescopic lock hole 9b and the opening 9m.

Next, the storage holder 9f is formed with a pipe attachment hole 9i. The storage holder 9f is attached to a groove formed on the side surface of the outer pipe with the attachment hole 9i facing outward. A storage opening 9j is opened at the front end side of the storage holder 9f, and the attachment claw 21 of the extension pipe 20 is inserted into the storage opening 9j, and the front end 21a of the attachment claw 21 and the pipe attachment hole 9i are engaged. They are fixed and held (see FIG. 13).
Further, the outer pipe 9 is formed with an anti-vibration rib 9k protruding from the side surface, and the outer pipe 9 is brought into contact with the shake holding rib 22 formed on the extension pipe 20 so as to prevent fluctuation when the attachment A is fixed to the extension pipe 20. It is preventing.

Next, referring to FIG. 10, the extension lock hole 9 b has an end surface 9 d on the side in which the inner pipe 10, which will be described later, enters the outer pipe interior 9, in the insertion direction of the inner pipe 10 (right direction in the figure). An inclined joint surface is formed.
In the present embodiment, the joint surface is formed with an inclination of 30 degrees in the insertion direction with respect to a line perpendicular to the insertion direction of the inner pipe 10 into the outer pipe 9.
As will be described later, the force applied in the insertion direction of the inner pipe 10 to the outer pipe 9 prevents the telescopic lock button 10a from entering the outer pipe 9 from the state where the telescopic lock button 9a is engaged. It is for doing so.

(About the inner pipe)
Next, mainly referring to FIGS. 1 to 4, the inner pipe 10 has a telescopic lock button 10 a on one end side, a holding body 10 b that holds the suction port 1 on the other end side, and housing of the outer pipe 10. A first moderation rib 10c and a second moderation rib 10h are formed to inform the state with a feeling of wearing.
The telescopic lock button 10 a protrudes from one side surface of the inner pipe 10, and a notch 10 e is formed around the inner pipe 10 so that it can enter the inside of the inner pipe 10 when pressed.

Referring to FIGS. 7 to 8, the holding body 10 b is a protruding portion having a substantially square shape in plan view that protrudes outward so as to be symmetrical on both side surfaces of the inner pipe 10, and is pressed. A notch 10d is formed around the periphery of the inner pipe 10 so as to enter the inside thereof.
The first moderation rib 10c is a projecting portion for generating moderation (sound and vibration) when the inner pipe 10 is fully projected from the outer pipe 9 into a moderation hole 9c described later. It is formed in the vicinity of the lock button 10a.
Further, the second moderation rib 10h is a projecting portion for generating moderation when the inner pipe 10 is stored in the innermost part of the outer pipe 9 in a moderation hole 9c described later. The inner pipe 10 is disposed on the side where the inlet 1 is attached.

Next, a stopper 10f protrudes from the position of the second moderation rib 10h of the inner pipe 10 on the tip side.
The stopper 10f prevents the fingers from being caught in the gap between the end face of the outer pipe 9 and the end face of the suction port 1 when the inner pipe 10 and the outer pipe 9 are contracted, and also prevents the inner pipe 10 from being injured. It is wider than the moderation rib 10c and protrudes so that it can be used as a finger hook when extending.
Further, a pressing portion 10g protrudes from the position of the stopper 10f of the inner pipe 10 on the tip side. The pressing portion 10g is a portion pressed by the user when the inner pipe 10 is extended, and is configured wider than the stopper 10f.

The inner pipe 10 and the outer pipe 9 that are configured as described above constitute the pipe portion P by being combined as follows.
First, in a state where the inner pipe 10 enters the innermost part of the outer pipe 9, that is, in a state where the attachment A is the shortest, the second moderation rib 10h formed on the side where the suction port portion 1 is attached is By entering the moderation hole 9c, the movement of the inner pipe 10 protruding outward from the outer pipe 9 is restricted, and the attachment A is in the shortest state.

Next, in a state where the inner pipe 10 is most exposed to the outside of the outer pipe 9 from the above state, that is, when the attachment A is in the longest state, first, a finger is applied to the pressing portion 10g and the stopper 10f to press By pressing the portion 10g, the second moderation rib 10h is detached from the moderation hole 9c, and the inner pipe 10 can protrude outside the outer pipe 9.
When the inner pipe 10 protrudes from the outer pipe 9 to the position where the attachment A is the longest, the first moderation rib 10c enters the moderation hole 9c and the telescopic lock button 10a engages with the telescopic lock hole 9b. Thereby, the attachment A can be held in the longest state.

  At this time, when the first moderation rib 10c is engaged with the moderation hole 9c simultaneously with engagement (locking) with the expansion / contraction lock hole 9b of the expansion / contraction lock button 10a, the deformation operation of the expansion / contraction lock button 10c returns to the normal position. Even if this is delayed, the first moderation rib 10c becomes a cushion, and the outer pipe 9 can be fixed to the inner pipe 10 at the correct position, and the operation when the attachment A is extended is stabilized.

Further, in the state where the telescopic lock button 10a is engaged with the telescopic lock hole 9b as described above, the end surface 9d of the telescopic lock hole 9b is formed with a joint surface that is inclined in the insertion direction of the inner pipe 10. Due to the force applied in the insertion direction of the inner pipe 10 to the outer pipe 9, the telescopic lock button 10a is configured to be difficult to enter the inner side of the outer pipe 9 from the state where the telescopic lock button 10a is engaged with the telescopic lock hole 9b.
That is, the telescopic lock button 10a contacts the end surface 9d by a force applied in the insertion direction and presses the end surface 9d. At this time, since a joining angle that is inclined in the insertion direction of the inner pipe 10 is formed on the end face 9d, an upward force is applied to the telescopic lock button 10a, and it rides on the end face 9d.

  Therefore, the expansion lock button 10a can be prevented from entering the inside of the outer pipe 9 by the force acting in the direction in which the inner pipe 10 enters the inside of the outer pipe 9 during use, and the attachment A is prevented from contracting unexpectedly. can do.

Next, when it is desired to shrink the attachment A from the above state, the telescopic lock button 10a is pushed to enter the inside of the inner pipe 10. As a result, the joined state between the end face 9d of the telescopic lock hole 9b and the telescopic lock button 10a is released, and the inner pipe 10 can be inserted into the outer pipe 9, that is, the overall length of the attachment A can be shortened.
In addition, since the notch 10d is formed around the expansion / contraction lock button 10a, the periphery of the expansion / contraction lock button 10a is easily elastically deformed with respect to the force in the direction of pushing the expansion / contraction lock button 10a, and the expansion / contraction lock button 10a. Is configured to easily enter the inside of the inner pipe 10.

The opening surrounded by the opening edge 2 is an opening for taking in dust from the surface to be cleaned, and the bristle brush 5 is used to scrape out the dust on the surface to be cleaned and not damage the furniture or the like. Has been. The bristle brush 5 is made of a flexible material such as nylon thread or horse hair.

Next, the side surface opening 3 includes a first opening 3a and a second opening 3b, and the first opening 3a and the second opening 3b are partitioned by a rib 3c. The opening holes 3 are open on the left and right side surfaces of the case 4, but the shapes of the holes 3 are symmetrical.
Next, on the inner surface of the case 4, grooves 4 m are respectively formed in the pair of walls 4 a at portions from the side opening 3 to the opening edge 4 d positioned in the long side direction of the rectangle formed by the side opening 3. Note that the long side of the rectangle formed by the opening hole 3 is parallel to the opening edge 2.

Next, the take-out knob 8 is separate from the case 4 and is a substantially “U” -shaped member in plan view comprising a pair of symmetrical side walls 8 a and a connection wall 8 b connecting the pair of side walls. It is.
On each of the left and right side walls 8a, a knob portion 8c having a shape spreading outward at a position far from the connection wall 8b, a claw portion 8d protruding outward at a position close to the connection wall 8b, and the knob portion 8c And a claw 8d is formed with a recess 8e.

In addition, a rib 8f is erected on the inner side of the picking knob 8 and on the back side of the knob 8c from the recess 8e toward the knob 8c.
The take-out knob 8 is formed to be elastically deformable so as to bend inward by pinching the pair of knobs 8c with a finger.

Referring to FIG. 5, the take-out knob 8 configured as described above is attached to the case 4 as follows.
The take-out knob 8 is inserted into the groove 4m from the opening edge 4d side of the case 4 while being narrowed in the direction in which the pair of side walls 8a approach each other from the connection wall 8b side.
Then, the take-out knob 8 inserted into the case 4 is inserted up to the position of the side opening 3 of the case 4, so that the side wall 8 a expands in the left-right direction by its own restoring force and fits into the side opening 3. . At this time, the knob portion 8c is fitted into the first opening 3b, and the claw portion 8d is fitted into the second opening 3a.
That is, the take-out knob 8 is attached to the side opening 3 from the inside of the case 4.

By positioning each part in this way, the rib 3c is fitted into the recess 8e of the take-out knob 8, and the take-out knob 8 is attached to the case 4. In this state, since the knob 8c is located in the opening 3b, the side wall 8a of the take-out knob 8 can be bent by pressing.
(Operation to attach the suction port to the inner pipe)

Referring to FIG. 8, the suction port portion 1 configured as described above is attached to the inner pipe 10 constituting the pipe portion P as follows.
First, the pair of holding bodies 10b of the inner pipe 10 is inserted into the groove 4m from the opening edge 4d side of the case 4, respectively.
At this time, since the opening width d1 of the opening edge 4d facing each other is narrower than the width d2 (see FIG. 7) between the respective tips of the pair of holding bodies 10b, the holding body 10b is pressed inward of the inner pipe 10. In this state, proceed inside the groove 4m.

In addition, the dimension between the opposing sides constituting the holding body 10b is configured to substantially match the width of the groove 4m, and the holding body 10b is configured to be movable within the groove 4m.
Further, since the notch 10d is formed around the holding body 10b, the surrounding of the holding body 10b is easily elastically deformed with respect to the direction in which the holding body 10b is pushed, and the holding body 10b becomes the inner pipe 10. It is configured to easily enter the inside.

And the holding body 10b which advanced inside the suction inlet 1 in a state where the groove 4m is pressed reaches the side opening 3 formed in the case 4 and protrudes into the side opening 3 by its own elastic force. It is held inside the opening 3.
At this time, referring to FIG. 5 and FIG. 8, the holding body 10 b is inserted in the side opening 3 between the rib 8 f of the take-out knob 8 and the insertion side edge 3 e and perpendicular to the insertion direction. The other direction is sandwiched between the edges 3f, which are the upper edge 3d, and the four sides of the holding body 10b are each sandwiched.

Further, the end of the holding body 10b in the protruding direction from the inner pipe 10 is in contact with the back side of the knob portion 8c of the extraction knob portion 8.
That is, the suction port 1 is attached to the inner pipe 10 with the pair of holding bodies 10b sandwiched by the take-out knob 8, and the holding body 10b can be pressed by pressing the knob 8c. Has been placed.

  The attachment of the suction port 1 to the inner pipe 10 has been described above. However, since the shape (plan view shape) seen from the protruding direction of the holding body 10b is configured as a regular square, the inner pipe 10 shown in FIG. Even when the inner pipe 10 is rotated 90 degrees about the holding body 10b (left rotation in the figure) from the attachment state of the suction port portion 1 to the suction port portion 1, the suction port portion 1 can be attached to the inner pipe 90. It is possible (for example, the state of FIG. 2).

Thus, since the suction inlet 1 can be attached in two different directions, the direction of the opening edge 2 that forms an opening for taking in dust from the portion to be cleaned can be selected according to the application.
Specifically, as shown in FIG. 1, if the suction port portion 1 is attached to the inner pipe 10 so that the opening edge 2 faces in the expansion / contraction direction of the attachment A, a form suitable for cleaning the floor surface or the like is obtained. be able to.
Moreover, if the suction inlet part 1 is attached to the inner pipe 10 so that the opening edge 2 faces in a direction perpendicular to the direction of expansion and contraction of the attachment A, the suction inlet part 1 is located at a position higher than the handle position. Since the bristle brushes face in parallel, the bristle brush can have a shape suitable for cleaning high places such as on a shelf or a lighting fixture.

In the present embodiment, the shape of the holding body 10b in plan view is described using a regular square shape, but is not limited to this shape. For example, when the suction port 1 is attached by changing the orientation of the holding body 10b, such as a regular hexagon, a regular octagon, etc., the interval width between the sides facing each other of the holding body 10b is the groove 4m. It only needs to be insertable with respect to the width.
Thus, by making the planar view shape of the holding body 10b polygonal, it can be configured such that the direction in which the suction port portion 1 faces can be selected.

(Operation to remove the suction port from the inner pipe)
Next, referring to FIG. 9, an operation when the suction port 1 is removed from the inner pipe 10 will be described.
First, the pair of holding parts 10b is pressed against the knobs 8c by respectively pressing and pressing the pair of knobs 8c from both sides. Then, the holding body 10b is elastically deformed so as to enter the inside of the inner pipe 10, moves to a position not facing the removal direction (downward in the drawing) of the insertion side edge 3e, and comes off from the edge of the side opening 3; The engagement state between the holding body 10b and the side surface opening 3 is released. That is, the holding body 10b is pushed out from the inside of the side opening 3 to the knob 8c, and the engagement state (holding state) between the holding body 10b and the side opening 3 is released.
In this state, the suction port 1 can be removed from the inner pipe 10 by pulling the inner pipe 10 in the direction of the groove 4m.

Therefore, according to the present invention, the suction port portion 1 can be configured to be attached in different directions, and when the brush or the like provided in the suction port portion 1 is worn, the user can easily make the suction port portion himself / herself. 1 can be removed and replaced.
Accordingly, it is possible to provide an attachment for a vacuum cleaner that does not cause waste such as a user requesting the manufacturer to replace the suction port 1 or purchasing the entire attachment.

Further, as in the present embodiment, the take-out knob 8 is formed of a member different from the case 4, so that when the holder 10 b is pressed, only the take-out knob 8 is bent, and the suction port portion 1 can be removed.
That is, since only a smaller portion is bent without bending the entire case 4, the suction port portion 1 can be taken out with a smaller force.

As mentioned above, although the suction port part 1 demonstrated the form comprised so that attachment or detachment was possible with respect to the pipe part P comprised so that expansion and contraction was possible, the pipe part P may not expand and contract.
Moreover, although the suction port part 1 demonstrated the form comprised so that attachment or detachment with respect to the inner pipe 10 was carried out, if the inner pipe 10 was provided so that entrance / exit was possible with respect to the outer pipe 9, and the attachment A was telescopic, The suction port 1 may be configured to be detachable from the outer pipe 9.
In this case, the connection part to the extension pipe 20 or the hose is formed in the inner pipe 10.

Next, the operation when the attachment A is stored after the cleaning is completed will be described.
