sucTIoN NozzLE FOR sUcTIoN CLEANERS Filed June 1s. 1947 INVENTOR Jon Van Der Heem ATTORNEYS Patented Jan. 6, 1953 Jan'van der Heem, Voorburg, Netherlands Application `Iune 13, 1947, Serial No. 754,357 In the Netherlands May 10, '1946 Section 1, Public Law 690, August 8, 1946 Patent expires May 10, 1966 Claims.
In order to be able, when using a suction cleaner, to displace the suction nozzle beneath iurniture and the like in a simple way, it is usual to provide a hinged junction between the suction nozzle and the suction tube which is to be held in the hand.
The hinged junction, however, introduces difculties because in all positions it must be air-tight. Moreover, such a hinge allows for rotaton in only one plane.
The present invention aims at; providing an air-tight universal connection between the nozzle and tube.
The nozzle according to the invention is mainly characterized in that it consists of an upper part of a strong resilient material, for example, rubber, closed at the lower side by a bottom of metal which is provided with one or more suction openings.
The invention will be disclosed and explained by reference to the accompanying drawing which forms part of this speciiication.
Fig. 1 is a vertical sectional View of one ernbodiment of the invention;
Fig. 2 is a similar sectional view of another embodiment;
Fig. 3 is a vertical sectional view of a further modification; and
Fig. 4 is a transverse view in sectional elevation of the nozzle shown in Fig. 3.
The mechanism of Fig. 1 comprises a suction nozzle, which can be pushed onto a tube l, and which has the usual external shape. However, according to the invention, the nozzle comprises an upper part 2 of rubber which ends in a short connecting tube 3 which fits onto the tube l.
The rubber part 2 which is zin. vthe nature of a deformable diaphragm ends at thev lower side in a circular edge I3, wherein a metal plate 4 is placed. The plate 4 has a at lower side, which can be moved over the floor and is provided with a central suction opening 5. The part 2 forms an upper mounting part. for the plate.
'In order to increase the elasticity of the whole, a circular `outward bulge 9 is desirablyv provided around the upper part.
When using a suction cleaner of this kind it is often desirable to increase the suction power locally. This is made possible in a simple way by the embodiment according to Fig. 2. The embodiment of Fig. 2 is generally similar to the embodiment of Fig. 1. Corresponding reference characters have accordingly been applied to corresponding parts with the subscript a added in each instance, and no general description will be given.
In this embodiment, however, the metal plate 4a isy formed in such a way that it is provided with twok suction openings or sets of suction openings 5a and 6a, to the front and rear of an intermediate boss. Further, the portion of the rubber part 2a which is situated at the back side between the boss and the rear extremity is formed to provide a thickened inwardly displaced enlargement. This enlargement is indicated at 1. If lit is desired to increase the suction power in a certain part of the floor it is possible, by turning the upper part of the tube piece la somewhat downward, to push the rubber part' 2a at'the back side so far downward that the inner part of the part 1 closes or partly closes the free space 8 above the opening 6a and rests on the `upper side of the plate 4a by which the back. suction opening 6a is closed off, in part at least, from communication with the tube la and only the opening 5a remains in operation. This increases thev suction power through the opening 5a.
The embodiment of Figs. 3 and 4 is generally similar to the embodiment of Fig. 2. Corresponding reference numerals have accordingly been applied to corresponding parts with the subscript b added in each instance, and no genera-l description will be given.
In Figs. 3 and 4, a brush l@ is iiexibly supported centrally at the lower side of the plate 4b, which can be operated at will. The brush 'l0 in its normal position is not in contact with the floor. The central portion of the plate 4b is desirably cut away and is replaced by a central brush supporting section 4c. The section 4c is movabl-y supported through a spring plate 4d.
When it is desirable, in using the suction cleaner, to treat a part of the floor also with the brush, a slight pressure exercised in avertical direction .on the tube piece Ib will result in some ridges l2, arranged in the interior of the suction nozzle, being displaced in a downward direction and. thereby exercising a-pressure on the upper side of the central part llc and the edge of an attaching Yplate Il which is fixed thereon, so that this vcentral part of the bottom 4b is displaced downward and the brush I0 is pressed upon the floor.
Iv have described what I believe to be the best embodiments of my invention. I do not wish, however, to be conned to the embodiments shown, but what I desire to cover by Letters Patent is set forth in the appended claims.
I claim:
l. A suction nozzle for a suction cleaner comprising, in combination, a suction tube, a generally rigid, substantially flat bottom plate having a suction opening therein, the bottom plate eX- tending both laterally and in a fore and aft direction for substantial distances outward from the end of the suction tube, a deformable diaphragm of highly resilient material extending atwise and covering the entire bottom plate, said diaphragm including a central, integral, tubular extension through which it is connected to the suction tube, said diaphragm with its tubular extension constituting the sole means of connection of the bottom plate with the suction tube, and being sufficiently yielding to enable the suction tube to have limited bodily and universal tilting movement relative to the bo-ttom plate.
2.
