Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention relates to an upright vacuum cleaner, and in particular,
The present invention relates to a connection structure between a vacuum cleaner body and a suction port body.

(Prior Art) Conventionally, an upright vacuum cleaner is known, in which an electric blower and a dust collection chamber are installed inside the vacuum cleaner body, and a suction port body is connected to the vacuum cleaner body with a long handle protruding through a connecting pipe. There is. In the conventional upright type vacuum cleaner of this kind, as described in Japanese Utility Model Application Publication No. 63-129556, the connecting pipe is made to be rotatable only in the front and rear directions with respect to the suction port body. However, with this structure, when cleaning by gripping the handle and sliding the suction port body on the surface to be cleaned such as the floor, the vacuum cleaner body cannot be moved from side to side with respect to the suction port body. Since it cannot be rotated, it is difficult to change the running direction of the suction port itself, making it difficult to use.

Therefore, in order to improve running mobility, the connecting pipe is connected to a first rotating pipe that is connected to the suction port body so as to be rotatable back and forth within a predetermined range, and the connecting pipe is connected to the first rotating pipe to rotate in the circumferential direction. By configuring the structure with a bent second rotating tube that is freely connected and connected to the vacuum cleaner body, the vacuum cleaner body can be swung not only in the front-back direction but also in the left-right direction with respect to the suction port body. A flexible structure is adopted. However, with this structure, when it is necessary to take your hand off the handle during cleaning or when storing it, the first rotation tube is rotated to the limit of its rotation range, and the vacuum cleaner body is placed upright, i.e., when it is stored. Even if you try to leave the vacuum cleaner positioned directly above the mouth body, the vacuum cleaner body is swingable relative to the suction mouth body, so it is unstable and tends to fall over.

Therefore, conventionally, as shown in FIG.
A convex portion 4 and a concave portion 5 that are engaged and disengaged from each other as a click mechanism.
A structure was adopted in which both were formed. However, with this conventional structure, not only when the vacuum cleaner body is standing, but also when the vacuum cleaner body is tilted in normal use,
Since the click mechanism works and the rotation in the left and right direction is restricted to some extent, it is difficult to move the suction port body 1 left and right, making it difficult to use. Further, due to long-term use, the convex portions 4 and the concave portions 5 wear out, which poses a problem in reliability.

Furthermore, conventionally, JP-A-6 3-1 9 7 4 2 1
As described in the above publication, a small round tapered convex portion is formed on the upper surface of the suction port body, and when the first rotation tube rotates to the maximum extent, the second rotation tube rotates. A structure has also been adopted in which a small recess is formed to fit into the convex part, and the horizontal rotation of the vacuum cleaner body is restricted only when the main body is approximately upright. However, in this conventional structure, since a recess is formed in the rotation tube, the depth of this recess cannot be increased. Therefore, when the convex part is tapered, when the vacuum cleaner body is stood upright, even if a small load is applied to the vacuum cleaner body from the side, the concave part easily comes off from the convex part, causing it to fall over. Cheap.

(Problem to be Solved by the Invention) As described above, the conventional upright vacuum cleaner body restricts rotation when the vacuum cleaner body is upright by fitting the convex portion of the suction port body with the concave portion of the second rotating tube. With light-type vacuum cleaners, there was a problem that the concave part could easily come off from the convex part.

The present invention aims to solve these problems, and is intended to provide a vacuum cleaner with a first rotary tube that can freely rotate back and forth and a second rotary tube that can freely rotate left and right in the suction port body. The purpose of this invention is to reliably prevent horizontal rotation of the vacuum cleaner body when the vacuum cleaner body is standing upright in an upright vacuum cleaner with a connected main body.

Furthermore, it is an object of the present invention to prevent the vacuum cleaner main body from rotating in the front-rear direction when the main body is standing upright.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a vacuum cleaner body provided with an electric blower and a dust collection chamber that communicates with the electric blower, and a vacuum cleaner body that protrudes from the vacuum cleaner body. a handle to be held when cleaning; a suction port body having a suction port on the lower surface and grounded on the surface to be cleaned; A first rotary tube connected in communication with the suction port, one end of which is connected and communicated with the first rotary tube so as to be rotatable with the axial direction being the rotation axis direction, and the vacuum cleaner main body. and a bent second rotary pipe connected to the dust collection chamber at the other end thereof, the suction port is formed from the rear side of the upper surface of the suction port main body to the rear surface thereof. Insert the first
or a second rotary tube is inserted therethrough, and locking convex portions are provided on the upper surface of the suction port main body and protrude in the left-right direction on both left and right sides of the insertion port, while the second When the first rotary tube reaches the limit of its rotation range and the vacuum cleaner body is positioned above the suction port body, the first rotary tube abuts on the outer peripheral surface of the second rotary tube, respectively. A locking protrusion that prevents the second rotating tube from rotating is provided in a protruding manner.

In addition, as the first rotation tube rotates, one of the locking convex portion of the suction port body and the locked convex portion of the second rotary tube is elastically attached to the other convex portion. A click convex portion that can be climbed over may be further provided in a protruding manner.

(Function) When cleaning, the upright vacuum cleaner of the present invention moves the suction port body over the surface to be cleaned while supporting the vacuum cleaner body by gripping the handle. The first rotating tube rotates with the horizontal direction as the rotating axis direction, and the bent second rotating tube connected to the vacuum cleaner main body rotates with respect to the first rotating tube as the axis. By rotating with the direction as the rotation axis direction, the suction port main body is easily moved back and forth, left and right, while the suction port is held in a state in which the suction port is closely opposed to the surface to be cleaned. Then, when you want to take your hand off the handle during cleaning or when storing it, you can rotate the first rotation tube upward to the limit of its rotation range, and only at this time can the second rotation tube be turned. The part of the pipe with the locking protrusion moves to the front of the insertion port of the suction port main body, and the part of the pipe that has the locking protrusion moves to the front of the insertion port of the suction port main body, and is attached to the locking projection located on the upper surface of the suction port main body and protruding from both left and right sides of the insertion port.
By abutting the locked protrusions on the outer circumferential surface of the second rotating tube, the second rotating tube and the vacuum cleaner body are prevented from rotating in the left-right direction, even if the handle is not gripped. The vacuum cleaner main body is positioned above the suction port main body and is stably maintained in a substantially upright state.

Furthermore, in the upright vacuum cleaner of claim 2, when the first rotating tube is rotated upward together with the vacuum cleaner body, the locked convex portion of the second rotating tube or the suction port body The click protrusion on one of the locking protrusions elastically rides over the other protrusion. Even if a weak external force is applied to the vacuum cleaner main body in an almost upright state, the click protrusion and the other protrusion engage with each other to prevent the vacuum cleaner main body and the first The rearward rotation of the rotation tube is prevented. Note that if the cleaner main body is rotated backwards with some force, the click protrusion elastically moves over the other protrusion in the opposite direction.

(Example) Hereinafter, the structure of a first example of an upright vacuum cleaner of the present invention will be described based on FIGS. 1 to 5.

11 is a case-shaped vacuum cleaner body, as shown in Fig. 4.
Inside the vacuum cleaner body 11, an electric blower 12 is disposed at the bottom in the figure, and a dust collection chamber 14 that communicates with the intake side of the electric blower 12 and has a detachable dust collection bag 13 built therein is provided. It is formed on the upper side in the figure, and a cord reel 15 is disposed further above this dust collection chamber 14. An exhaust port 16 communicating with the exhaust side of the electric blower 12 is formed in the cleaner body 11. Further, an opening is formed in the cleaner body 11 facing the dust collection chamber 14, and this opening is closed by a detachable lid 17 so as to be openable and closable. Furthermore, a long rod-shaped handle 1B extending in the longitudinal direction is provided protruding from one longitudinal end surface, that is, the upper end surface of the vacuum cleaner main body 11, and a grip portion 19 for operation is provided at the tip of the handle 18. It is provided.

Reference numeral 21 denotes a suction port main body, and as shown in FIG. 3, this suction port main body 21 is composed of a lower case 22 with an open top surface and an upper case 23 with an open bottom surface. A bumper 24 is sandwiched between the peripheral edges of 23. A suction port 25 is formed in the lower surface of the lower case 22.
A brush 26 or a lip piece is provided protrudingly located on the rear side of 5. Further, a pair of left and right front wheels 27 and a rear wheel 28 are pivotally attached to the front and rear parts of the lower surface of the lower case 2z, respectively.

Further, as shown in FIG. 1, an insertion port 31 is cut out from the rear side of the upper surface of the suction port body 21 to the rear surface thereof. Upper case 22 in this insertion hole 31
The inner edge of the portion located on the top surface is approximately U-shaped with an opening toward the rear. And the push-through port 3 in this part
Locking convex portions 32 that protrude toward the center of the insertion opening 31 in the left-right direction are integrally formed on the front portions of both left and right side surfaces of the insertion port 1 .

Note that the rear portions of these locking convex portions 32 are respectively inclined portions 33 that are inclined outward in the left-right direction toward the rear. Furthermore, stopper portions 34 are provided at the front edge and the lower edge of the insertion opening 31, respectively, and are bent downward and upward. 3
5 is formed.

41 is a first rotating tube, and this first rotating tube 41 includes a semi-cylindrical portion 43 having an axial direction in the left-right direction and a suction opening 42 on one side of the circumferential surface, and is integrated with this semi-cylindrical portion 43. A cylindrical connecting portion 44 is formed perpendicularly to each other.

The semi-cylindrical portion 43 having support shaft portions 45 on both axial end surfaces is connected to both cases 22 of the suction port main body 21. 23
The suction port 25 of the suction port main body 21 and the inside of the first rotation tube 41 are connected to each other, and the insertion port 31
is inserted through the connecting portion 44 and protrudes rearward and upward. Furthermore, protrusions 46 and 47 are formed on both circumferential edges of the suction opening 42 of the semi-cylindrical portion 43, respectively. These protrusions 46 and 47 form the stopper portion 34 of the suction port body 21. 35, the rotation range of the first rotation tube 41 is restricted to a predetermined range, and the first rotation tube 41 is
At the upper limit of the rotation range, the connecting portion 44 is directed upward as much as possible.

51 is a second rotating tube, and this second rotating tube 51 is approximately
It is formed into a cylindrical shape with a curved shape.

A connecting portion 52 formed with an enlarged diameter at one end of the second rotating tube 51 is connected to the connecting portion 4 of the first rotating tube 4I.
These connecting portions 44. 52 as the rotational axis direction, and both the rotation tubes 41. The inside of 51 is communicated with each other.

Further, the other end of the second rotating tube 51 is substantially perpendicularly and fixedly connected to the longitudinal end surface of the cleaner main body 11 from which the handle 18 is not protruded, that is, the lower end surface. The vacuum cleaner body 11 is connected to the dust collection chamber 14 through a communication pipe 53 provided inside the cleaner body 11.

As shown in FIG. A pair of locked protrusions 54 having a substantially triangular cross section perpendicular to the axial direction are integrally formed to protrude outward, and the cross-sectional shape of the outer peripheral surface of the connecting portion 52 is non-circular. . This connection part 52
The distance r from the central axis to the top edge of the locking protrusion 54 and the left-right width L1 of the portion of the insertion port 31 of the suction port body 21 rearward from the locking protrusion 32 are as follows: L, ≧2
A relationship r is set. On the other hand, the distance L2 from the symmetrical plane of the second rotating tube 51 including the central axis of the second rotating tube 51 to the side surface of the locked protrusion 54, The distance L3 to the side surface is approximately equal to the distance L3. In addition, these locked convex portions 54 and locking convex portions 3
The distances from the second support shaft portion 45 are also approximately equal.

Therefore, only when the first rotation tube 41 is rotated upward to the maximum extent, both locked convex portions 5 of the second rotation tube 51
4 are in contact with both locking convex portions 32 of the suction port body 21, respectively, so that the second rotation pipe 51 is prevented from rotating. Note that when the first rotating tube 41 is rotated upward to the maximum extent, the vacuum cleaner main body 11 stands almost upright, and the center of gravity of the vacuum cleaner main body 11 is in front of the support shaft 45 of the suction port main body 21. The bending angle of the second rotation tube 51 is set so that it is located above between the front wheel 27 and the rear wheel 28.

Next, the operation of the above embodiment will be explained.

When cleaning, the front wheels 27 and rear wheels 28 of the suction port main body 2l
is grounded on a surface to be cleaned 60 such as a floor, and while supporting the cleaner body 11 by gripping the grip part 19 of the handle 18, the suction port body 21 is moved on the surface to be cleaned 60. Then, by driving the electric blower 12 in the vacuum cleaner body 11, the dust sucked in from the suction port 25 of the suction port body 21 is transferred to the dust collection chamber in the vacuum cleaner body 11 via both rotating pipes 41, 5+. guided by.

By the way, in a normal usage state in which the suction port body 21 is positioned further forward than the handle 18 and the vacuum cleaner body 11 is tilted backward by a certain angle or more, the second rotation tube 51 is moved as shown in FIG. Since the engagement between the locked convex portion 54 and the locking convex portion 32 of the suction port main body 21 is released, the first rotation pipe 4
Not only the rotary tube 1 but also the second rotary tube 51 can be freely rotated. The first rotating tube 41 rotates in the front-back direction with respect to the suction port body 21, and the second rotating tube 51 rotates in the circumferential direction with respect to the first rotating tube 41. Accordingly, the suction port main body 21 can be easily and smoothly moved back and forth and left and right while keeping the suction port 25 close to and facing the surface to be cleaned 60. That is, as shown in FIG. 5, when the grip portion 19 at hand is rotated left and right, the direction of the suction port body 21 changes accordingly, making it easier to use.

When the handle 18 is temporarily removed during cleaning or when the handle 18 is stored, the first rotary tube 41 is rotated to the upper limit of its rotation range as shown by the solid line in FIG. 11 is stood up almost vertically, the front end of the second rotating tube 51 with the locked protrusion 54 is connected to the insertion port 31 of the suction port main body 21.
is inserted into the front part of the insertion opening 31, and each side surface of both locked projections 54 abuts against the locking projections 32 on both sides of the insertion opening 31. This makes it impossible for the second rotation tube 51 to rotate with respect to the suction port body 21, so that the swinging movement of the cleaner body 11 in the left-right direction is also prevented. Therefore, even if the handle 18 is not gripped, the vacuum cleaner main body 11 maintains a stable posture.

By the way, as mentioned above, the locking convex portion 54 is attached to the locking convex portion 32.
When engaging the two, the front end of the second rotating tube 51 may be inserted entirely between the locking projections 32 on both sides of the insertion port 31 of the suction port body 21. The locked convex portion 54 can be smoothly engaged with the portion 32. Moreover, since the sloped portion 33 is formed at the rear of the locking projection 32, the locking projection 32 is guided by these slopes 33.
The engaged protrusion 54 can be more smoothly engaged with the protrusion 54.

Furthermore, the locking protrusions 32 that protrude in the left-right direction from both left and right side surfaces of the insertion port 31 do not protrude outward from the suction port body 21, so they do not spoil the appearance or become a hindrance. Moreover, when the locking convex portion 54 on the outer peripheral surface of the second rotation tube 5l is brought into contact with the locking convex portion 32 in such a position, these convex portions 32. 54 without increasing the amount of protrusion of these convex portions 32. The contact area of 54 can be increased. Therefore, the strength can be increased and the resistance to the force that forces the second rotating tube 51 can be increased, so that the suction opening main body z1 and the second rotating tube 51 can be locked when the vacuum cleaner main body l1 is upright. The vacuum cleaner main body 11 can be made reliable, and even if only a small external force is applied to the standing vacuum cleaner main body 11, the vacuum cleaner main body 11 will not fall down, making it safe.

Next, a second embodiment of the present invention will be described based on FIGS. 6 and 7.

In this embodiment, a portion of the top edge of a pair of locking convex portions 54 having a triangular cross section formed on the outer circumferential surface of the second rotation tube 51 is further provided outwardly, that is, in a direction away from each other. The protruding click convex portions 61 are each integrally formed. These click convex portions 61 are connected to the first rotation tube 41.
is formed at a position above the locking projection 32 of the suction port body 21 corresponding to the locking projection 54 when the vacuum cleaner main body 11 is rotated upward to the maximum extent and becomes almost upright. Also,
The suction port body 21 and the rotating tube 4I. 51 is made of an elastic material, but in its natural state, the distance L3 from the symmetrical plane of the second rotation tube 51 to the side surface of the locking protrusion 32
is slightly smaller than the distance L4 from the same plane of symmetry to the tip of the click protrusion 61 (L3 < L4).

Therefore, when the tenth rotation tube 41 is rotated upward, both sides of the insertion port 31 are turned outward from each other before the vacuum cleaner main body 11 changes from a backwardly tilted state to a vertically standing state. The click convex portion 61 rides over the locking convex portion 32 while the suction port main body 21 is elastically deformed so as to be displaced to , and the rotation tube 51 is elastically deformed in a direction in which L4 becomes smaller. When the vacuum cleaner main body 11 is in a vertically standing state, the first rotary tube 41 is locked by the engagement between the click protrusion 61 and the locking protrusion 32, and the rear of the vacuum cleaner main body 11 is rotation is prevented to some extent. That is, the vacuum cleaner body 1
Since the vacuum cleaner main body 11 can resist to some extent the rearward external force applied to the vacuum cleaner main body 11, the stability of the upright state of the vacuum cleaner main body 11 is further increased.

Moreover, if the vacuum cleaner main body 11 is rotated backwards with some force, the click protrusion 61 will elastically go over the locking protrusion 32 downward, and the lock of the first rotation tube 41 will be released. be done.

Note that the click convex portion may be provided in the locking convex portion 32 of the suction port body 21 instead of the locked convex portion 54 of the second rotation pipe 51.

Next, a third embodiment of the present invention will be described based on FIG.

In this embodiment, an auxiliary stand 62 is provided at the rear of the vacuum cleaner body 11 and protrudes downward from the lower end surface of the vacuum cleaner body 11.
is supported so that it can freely slide up and down. This auxiliary stand 6
2 protrudes downward to the maximum extent and when the cleaner main body I1 is substantially upright, its lower end touches the ground together with the rear wheel 28 and the front wheel 27 further behind the rear wheel 28 of the suction port main body 21. The auxiliary stand 62 is held with respect to the cleaner body 11 at a position where it is housed within the cleaner body 11 and at a position where it protrudes downward as far as possible.

During normal cleaning, the auxiliary stand 62 is stored inside the vacuum cleaner main body 11 as shown by the chain line, but when the vacuum cleaner main body 11 is stored almost upright, the auxiliary stand 62 is stored as shown by the solid line. 62 is extended downward, and the lower end of this auxiliary stand 62 is grounded together with the front wheel 27 and rear wheel 28 of the suction port body 21 on the surface to be cleaned 60 such as the floor. In this state, the auxiliary stand 62 reliably restricts the rearward rotation of the cleaner body 11.

According to this configuration, the resistance force against external force toward the rear is further increased than in the second embodiment, so that the vacuum cleaner main body 1
The stability of the state where 1 is standing increases even more.

FIG. 9 shows a fourth embodiment of the present invention. In this embodiment, an auxiliary stand 62 having the same function as the auxiliary stand 62 of the third embodiment is connected to the cleaner body 11 by a hinge 63. It is supported in a flexible manner.

That is, normally, as shown by the chain line, the vacuum cleaner main body 11
The auxiliary stand 62 is stored along the rear surface, but when setting up the vacuum cleaner body, rotate the auxiliary stand 62 downward about the hinge 63 as shown by the solid line.
The lower end of this auxiliary stand 62 is grounded to the mounting surface 60.

〔Effect of the invention〕

According to the present invention, the following effects can be obtained.

In the upright vacuum cleaner of claim 1, the suction port body includes a first rotary tube that can freely rotate with the left and right direction as the rotation axis direction, and a first rotary tube that can freely rotate in the circumferential direction with respect to the first rotary tube. Only when the vacuum cleaner main body connected via the bent second rotating pipe is located above the suction port main body, the rotating pipe Locking protrusions are provided on both left and right sides of the upper surface of the insertion hole of the suction port body through which the suction port is inserted, and the first rotation tube is rotated to the maximum extent on the outer peripheral surface of the second rotation tube. Since the locking protrusions that come into contact with both of the locking protrusions are provided in a protruding manner, the contact area of these protrusions can be increased without increasing the amount of protrusion of these protrusions. In addition to increasing the strength, when the first rotating tube is rotated to the maximum extent and the vacuum cleaner body is stood up, it is possible to reliably prevent the vacuum cleaner body from rotating in the left and right direction, and it is possible to prevent some external force from rotating. Even if the vacuum cleaner is exposed to water, it will not fall over and is safe. Furthermore, when engaging the locked protrusion with the locking protrusion, the portion of the second rotation tube with the locked protrusion may be inserted between the locking protrusions of the insertion port. Therefore, the locked projection can be smoothly engaged with the locking projection.

Furthermore, in the upright vacuum cleaner of claim 2, one of the locking convex portion and the locked convex portion is elastically attached to the other convex portion as the second rotation tube rotates. Since the click protrusion that can be climbed over is provided in a protruding manner, when the vacuum cleaner body is erected, it can resist external force to a certain extent to the rear, thereby increasing the stability of the erected state of the vacuum cleaner body.
