DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a device for pesticide-treating a sleeping mattress having a free internal space and in particular a spring mattress.
The French patent FR-A-92 07870 in the name of the Applicant refers to a mattress equipped with means for diffusing pesticide products and/or odorous products appearing in a solid form by insetting a cassette placed on the portion of the mattress containing these solid products.
The air, circulating from the outside of the mattress towards the inside, favours the sublimation of the pesticide and/or odorous products, whilst ensuring a continuous treatment of the inside of the mattress.
If this disposition may be satisfactory, the production of the solid products poses several problems and in particular certain products may be impossible to solidify or their sublimation speed may be uncontrollable.
In all cases, dosing is delicate as it varies considerably according to the temperature and hygrometric conditions. Moreover, certain products are permitted in the form of a periodic local treatment but are prohibited in a small continuous dose.
The present invention concerns a simple device which is permanently fixed on the lateral strip of the mattress and which simultaneously ensures ventilation and treatment by pesticides, that is by insecticides/bactericides and fungicides, which enables all powdered or gaseous products to be introduced, which uses under pressure gas-propellant receptacles or manual pressure ejection receptacles, which ensures a good diffusion of the treatment agent inside the free internal space according to the treatment agent, and which is small since it only uses static elements for diffusion, which permits the choice of agents and the periodicity of treatments.
To this effect, the device of the invention for the sanitary treatment of a sleeping mattress and more particularly a spring mattress, including a free internal volume delimited by the upper and lower faces and a peripheral lateral strip, the springs being disposed in said free volume, as well as ventilation means fitted in the lateral strips, is characterised in that it includes means for injecting under pressure a treatment gas in the form of a powder or gas contained in a receptacle with means for propelling said treatment agent and a distribution head.
More specifically, the injection means include at least one base integral with the lateral strip provided with at least one injection housing for receiving the distribution head and means for diffusing the treatment agent in the free space.
These diffusion means include a common diffusion channel with a length exceeding the thickness of the lateral strip so as to open into the free space.
According to one particular characteristic of the invention, the diffusion channel includes diffusion orifices whose number and orientation depends on the physico-chemical parameters of the treatment agent.
In addition, the base includes static ventilation means disposed immediately close to the injection housing.
This base includes a movable ventilation, flap covering the static ventilation means and the injection housing.
The housing between the static grill and the mobile flap is provided to receive a product in a bag.
The present invention is described hereafter according to a preferred non-restrictive embodiment with reference to the accompanying drawings which represent on the various figures:
FIG. 1, a perspective view of a mattress portion equipped with a base according to the invention with a receptacle containing the treatment agent,
FIG. 2 is a front view of the base of the device of the invention,
FIG. 3 is a cutaway view by a median horizontal plane of FIG. 2, and
FIG. 4 is a cutaway view by a vertical plane along the line 4--4 of FIG. 2.
FIG. 1 shows at 10 the mattress including a top 12, a bottom 14 and a lateral strip 16 which delimits an internal free space 18 visible on FIG. 4. It is to be noted that this space is solely occupied in an extremely limited way by the springs, one copy 18 being diagramatically drawn.
