This invention relates to nozzles for vacuum cleaners and more particularly to nozzles having a narrow elongated body intended for cleaning objects having narrow openings or corners. Such nozzles are frequently formed as an elongated flattened tube with or without a brush mounted in the mouth thereof.
In prior constructions of such nozzles a brush member rigidly connected with a holder consisting of metal guide members intended for insertion into the tube has been provided. with apertures or the like adapted to receive screws passing through the tube wall from the outside to retain the brush member in position. Such a construction is disadvantageous in that the brush cannot be removedwithout the use of tools so that the nozzle is not immediately applicable for use with or without the brush mounted thereon. Moreover, the guide members disposed Within the tube set up a comparatively high resistance to air flow.
A further known construction has included a brush member formed with a tubular metal shank into which the tubular member of the nozzle is inserted. In this construction the tubular form of the holder increases the width of the nozzle and prevents the nozzle being utilized for cleaning the same size gaps or narrow spaces with and without the brush.
One object of this invention is to provide a vacuum cleaner nozzle having a removable brush member which is simple and cheap to produce. A further object of the invention is to provide a brush member intended to be applied to and removed from a nozzle in a ready manner without the use of tools.
According to the present invention a brush intended to be readily replaceably mounted on a vacuum cleaner nozzle includes securing means in the form of a resilient stirrup serving as a support for the brush element and having its two ends relatively resiliently biased for engagement with recesses, apertures or the like formed in the wall of the nozzle body for holding said stirrup on the body.
More specifically, according to the invention, the brush includes a resilient stirrup carrying the brush element and having its two ends resiliently biased to engage with recesses, openings or the like of the nozzle body and to main tain such stirrup in position by said resilient bias-- ing, the stirrup having one or more re-entrant portions adapted to cooperate with the nozzle body to prevent lateral displacement of the stirrup.
The invention also includes a vacuum cleaner nozzle including a removable brush element mountedadjacent the nozzle mouth which comprises a nozzle body of flattened hollow form hav ing its walls formed with recesses, apertures or the like, and a resilient stirrup carrying the brush element having its ends biased resiliently to engage with the apertures or the like, the nozzle body and the stirrup having co-operating portions which are relatively re-entrant and act to prevent lateral displacement of the stirrup relatively to said body.
The invention will be hereinafter more fully described with reference to the accompanying drawings showing one embodiment by way of example. In the'drawings- Fig. 1 shows a side elevation, partly in section, of one form of nozzle fitted with a brush according to the invention;
Fig. 2 shows the brush by itself, also in side elevation; and
, Fig. 3 is a sectional view taken on line III-III of Fig. l.
Referring to Fig. 1, l0 designates a nozzle body consisting of metal, synthetic resin or similar material, which, as shown, has a flattened tubular head H and a round tubular shank [2 to which a hose of the vacuum cleaner is adapted to be connected. The opposite end S3 of the nozzle body forming the mouth is for practical reasons cut at an an le of about .5" to the longitudinal axis of the tube.
The brush element comprises a stirrup Id which is preferably made of spring wire and forms a holder for the brush I 5. The two limbs iii of the stirrup, which on application to the nozzle are disposed adjacent the short curved sides of the nozzle body, are at their ends bent out to form eyes H, the ends iii of which are resiliently biased to project into two openings I9 formed in the wall of the nozzle and thus retain the brush on the nozzle body.
In order to provide lateral guidance of the stirrup relative to the nozzle body, its central portion 2!) is bent in re-entrant shape in such manner as to encircle the edge of the nozzle mouth and also to project some distance into the mouth. The stirrup preferably bears resiliently against the edge of the mouth and/or against the curved sides of the nozzle.
The eyes i! serve as handles for applying the brush to the nozzle when it is desired to clean the slots of a heating element, such as a radiator, for example; and for removing the brush when it is desired to clean with the nozzle member only as when cleaning the corners of upholstered furniture, such as easy-chairs and the like, for ing formed so that the nozzle walls serve as :1 example. The brush element [5 includes bristles guide therefor, said resilient stirrup member which are secured in a well known manner by a having a relatively Small cross-Sectional area twisted wire core which comprises woven relative to its length and the limbs thereof being strands ofwire having its two end portions 2! 5 under tension an Spring pressed toward one clamped in two U-shaped sleeves 22 which are another to cause the ends of the limbs to be preferably welded to the stirrup l4. firmly held in the recesses when the stirrup It will now be understood that the c ossmember is mounted on the nozzle body and the sectional area of the stirruphlember ljis'relav limbs overlie the exterior surfaces of the narrow tively small compared to its length and the limbs end walls'in a direction lengthwise of the nozzle 16 thereof are under tensionand spring pressed body, atleast the transverse connecting part and toward one another to cause'the ends it} of the portions of the-limbs projecting beyond the narlimbs to be firmly held in the recesses l9 when row elongated op n n in disposed in a space the stirrup member is mounted on the head ll defined by imaginary spaced apart planes flush of the nozzle body In.
