Definitions
- the present invention relates to a vacuum cleaner for dust and other waste of the kind comprising a rigid suction tube intended to be held by the user and connected to a suction head.
- Known dust extractors include a substantially flat suction head having relatively large dimensions on either side of the end of the suction tube.
- This type of suction head is perfectly suited for cleaning open surfaces, but it is practically unusable for cleaning corners, edges at the bottom of walls and more generally reduced or narrow spaces.
- This type of suction head is also not suitable for effectively treating stubborn dust which requires a strong localized suction depression. Careful work therefore requires in these cases the use of a suction head of smaller dimensions which combines great maneuverability and a strong suction depression.
- Reversible suction heads which combine, on two opposite faces, two suction surfaces, one narrow and the other of usual dimensions. Depending on the desired use, the suction head is pivoted to apply one or other of the suction faces to the surface to be cleaned.
- Such a suction head does nothing to solve the problem of the size of the suction head, since the latter cannot be used effectively in the corners of the room to be cleaned whatever the suction face chosen.
- the present invention aims to solve the problem thus posed by simple and effective means which do not substantially modify the usual appearance of the vacuum cleaner.
- the vacuum cleaner for dust and other waste comprising a rigid suction tube connected to a suction head
- this suction head communicates with the suction tube via a connector in which the free end of the suction tube is slidably mounted and in that this connection comprises means for allowing the free end of the rigid suction tube to pass through the raccoard so as to be able to bear on the surface to be cleaned at instead of the suction head, these means making it possible to transmit the vacuum from the tube to the suction head, as long as the end of the tube is inside the fitting.
- the connector has a bend and the wall of the connector has, in the vicinity of the bend, an opening closed by a valve and located in the axis of the rigid suction tube, this opening being adapted so that the The free end of the suction tube can pass through it when the user slides the fitting relative to the rigid suction tube.
- the suction head is pivotally mounted at one of the ends of the connector.
- the suction head does not interfere with the visibility of the user.
- FIG. 1 is an elevation view with cutaway of the suction tube, of the connector and of the suction head of a vacuum cleaner according to the invention
- FIG. 2 is a perspective view of the suction tube, the connector and the suction head of this vacuum cleaner
- FIG. 3 is a view similar to FIG. 1 but without cutaway showing the normal working position of the vacuum cleaner
- FIG. 4 is a view similar to FIG. 3 showing the suction head raised and partially pivoted
- FIG. 5 is a view similar to Figure 4 showing the rigid suction tube pressing against the valve
- Figure 6 is a view similar to Figure 4 showing the suction head in the fully pivoted position and the end of the suction tube resting on the ground.
- the vacuum cleaner for dust and other waste comprises a rigid cylindrical suction tube 3 intended to be held by the user and connected to a suction head 1 of conventional type, this is - ie substantially flat and having a relatively large size, on either side of the tube 3.
- This suction head 1 communicates with the suction tube 3 via a tubular connector forming a sheath for the tube 3
- the suction tube 3 is slidably mounted in this connector 2 which is constituted by two tubular elements 2a, 2b straight and cylindrical forming between them a bend 2d.
- the suction head 1 is connected to the connector 2 by means of a suction duct which is pivotally engaged on the connector element 2a.
- the axis XX ′ of the connecting element 2a is substantially parallel to the surface to be cleaned 20.
- the angle b between the two connecting elements 2a and 2b is between 90 ° and 160o and advantageously equal to about 135 ° as in the example described.
- the wall of the tube element 2a has in the axis Y-Y 'of the suction tube 3 an opening 2c closed by a valve 4.
- This opening 2c is optionally surrounded by a seal, not shown, which allows the valve 4 to close this opening in a sealed manner.
- This opening 2c is adapted so that the free end 3a of the rigid suction tube 3 can pass through it, when the user slides the fitting relative to the rigid suction tube 3.
- the end 3a of the tube d 'suction 3 has an opening 3b oblique to the axis YY' so as to be substantially parallel to a horizontal plane passing through the axis XX '.
- the valve 4 is articulated near the opening 2c: one of its ends forming a yoke 4b is pivotally mounted on a spindle 6 carried by a lug 16 carried by the tube element 2b in the vicinity of the bend 2d.
- the valve 4 is applied against the opening 2c in an elastic manner by means of a spring 15 surrounding the pin 6, one end of which bears against the valve 4 and the other end of which bears against the tube element 2b. The vacuum tightly presses the valve 4 against the opening 2c.
- the suction head 1 is pivotally mounted relative to the element 2a of the connector 2.
- This suction head 1 also comprises a ballast 17 arranged in one of its lateral ends so that this head 1 can pivot around the 'axis XX' at a certain angle as shown in Figures 4 and 5, when the suction head 1 is raised.
- the side 1a of the suction head 1, adjacent to the connector 2 has a bearing surface 5 forming a cam to complete the pivoting of the suction head from the position according to FIGS. 4 and 5 towards an angular position situated substantially at 90 ° from the normal position (see Figure 6).
- This bearing surface 5 extends on the side of the suction head 1 which includes the ballast 17 and in the example shown, shaped so as to form an arcuate ramp according to an involute of a circle.
- the suction tube 3 has a longitudinal rib 7 engaged in a complementary groove 12 formed in the connector 2, which makes it possible to guide the sliding of the suction tube 3 along the axis YY 'and to prohibit the pivoting of that -this in the connector 2.
- the rib 7 has two recesses forming keepers 8a and 8b (see FIG. 1) into which a cleat 10 fixed in the vicinity of the end 9 of the element of the tube 2b in which is engaged the suction tube 3.
- the stopper 10 has a return spring 13 which pushes it towards the suction tube.
- This cleat 10 locks the sliding of the suction tube 3 in the connector 2 according to two positions: a so-called high position (see Figures 1 and 3) in which the cleat 10 is engaged in the keeper 8b, which corresponds to normal use of the vacuum cleaner, the suction being carried out by the suction head
- the suction tube 3 also has on its outer surface engaged in the fitting
- FIG. 1 a shoulder 18 (see FIG. 1) serving as a stop for a helical spring 13 surrounding the suction tube 3 and bearing against a ring 14 fixed inside the connector 2.
- This ring 14 serves as a slide and performs the tightness between the outer surface of the tube 3 and the connector 2.
- the spring tends to return the tube 3 to the normal position of use shown in FIGS. 1 and 3.
- the operation of a vacuum cleaner according to the invention is described below. -after with reference to Figures 3, 4, 5 and 6.
- Figure 3 shows the vacuum cleaner in its normal position.
- the valve 4 subjected to the return force of the spring 15 as well as to the suction force hermetically closes the opening 2c made in the tube 2a.
- the bearing surface 5 forming a cam prohibits the opening of the valve 4, when the tube 3 is pushed into the connector 2 without having previously raised the suction head.
- FIG. 4 shows the first step of the operation of outputting the suction tube 3 through the opening 2c.
- the operator lifts the suction head 1 from the surface to be cleaned 20, which causes the rotation of the suction head 1 around the axis XX 'under the effect of the ballast 17 disposed at one of its lateral ends.
- a rotation of the suction head 1 is caused at an angle between 45 ° and 60 ° relative to its normal position of horizontal use.
- FIG. 5 illustrates the second step of the operation for removing the suction tube 3.
- FIG. 6 shows the end 3a of the suction tube 3 in the fully extended position and bearing on the ground 20.
- the suction tube 3 is locked in this position by means of the cleat 10 engaged in the keeper 8a.
- the suction head 1 is kept substantially vertical with respect to the surface to be cleaned 20 because the lateral part of this head 1 containing the ballast 17 abuts against the tube 3a.
- the suction head 1 does not interfere with the visibility of the user, or the accessibility of the end of the tube 3 in the corners of a room to be cleaned.
- the return spring 13 comprised between the tube 3 and the connector 2 could be eliminated, which would make it possible to remove the shoulder 18, to reduce the diameter of the connector 2, and to obtain a greater output from the tube 3.
- ballast 17 could be replaced by a spiral torsion spring mounted on the suction pipe le of the suction head.
