Screening device for sun rays with changing positioning and orientating

The invention refers to a parasol device,with variable positioning on the car top and which can be differently oriented on the supporting stem to allow the position adjustment to the contingent employ requirements.the invention mainly permits to determine a screening device for the sun rays and to avoid in this way the car body overheating and,therefore,the driver discomfort as well as the relevant wear of car structures with an exceeding fuel evaporation.By further orienting the sunshade partly on the car and partly on the adjacent space,this one can be put under the shade thus permitting to use the parasol for protection in the open air for people and with possible employ of camping implements.

The protection of motor cars from the sun rays is at present possible but in stop stations conveniently equipped or by taking advantage of casual protections,such as those offered by trees and building parts.The invention permits to equip the car with a lodgeable accessory when not in use,in the ordinary space of the luggage boot,to be quickly mounted on the car top and positioned and oriented,in employ station,by means of simple mnemonic operations,thus permitting to stop the car in any place wha tever.

The sunshade presence,in fact,enables to screen the sun rays and the ventilation of the interspace avoiding the car body o-overheating.

Substantially,the means foresees a couple of parallel guides transversally laid and immediately above the car top,to be made integrally operating with it by means of conventional quick coupling devices on the side reliefs,which therefore act as longitudinal gu ides for the choice of their positioning points.These guides bear an emplacement with transversal sliding equipped with locking means for fixing them in stationing position.

The emplacement can thus be brought by sliding on the two above me ntioned couples of orthogonal guides in the chosen position of employ.This emplacement foresees centrally a cylindrical body in ele vation suitable for operation as coaxial for coupling the correspo nding axial part of the screen rod,which is thus brought by insertion in employ position.

As a choice version,the parasol stem foresees,in a position immediately above it,the axial part of the clutch,an articulation per mitting to turn and change the screen orientation.In this way,by properly adjusting the emplacement stationing point and the rod orientation,the screening device can be arranged according to the contingent requirements of employ. The integrally operating composition of the screen with the emplacement can be obtained by means of a clamping device passing through the locking parts of the clutch. The device is thus stabilized in the chosen position for employ and the parts are anchored which moreover operates with a-ntitheft effect.To permit the variability of the anchoring position,the clutch axial cylinder foresees a spaced set of bore couples on a circumference,positioned on the diameter,to be brought into position by turning;the bores are foreseen to correspond co- planarly to the coaxial to insert,in order to obtain the integral locking of the parts by a through clamping means.

A not limiting version of execution for this procedure is illustrated by the drawings of Table I,where Fig.I is a partial view of the transversal guides represented as supported on one si de,on quick clutch devices and bearing the emplacement,showing the initial part of the rod equipped with articulation and locking bores in station in pre-inserting position.Fig.2 is the view from above of the emplacement showing the two couples of gliding bodies,two of which equipped with screew locking knobs -for settling the emplacement on the transversal guides.Fig.3 is the longitudinal section of the emplacement bearing the stem in lock ed condition.These parts are connected by means of a padlock.Fig. 4 is the explanatory representation of the invention employ possibilities and illustrates a motor car stationary with a mounted parasol oriented so as to determine a shadow zone used to shield the car body and a portion of ground to permit the stop in a sha dowed zone for persons and things.For stationing,as a version,tra nsversal guides I and 2 are foreseen,firmly fitted on the car si de reliefs 3 by conventional quick connection joints.Emplacement 5 employs a system of ribs 6 for strengthening and central cylin drical part 7 which operates as a clutching coaxial and two couples 8 and 9 of containing parts for the emplacement gliding on the guides,of which 8 is equipped with screwed knobs permitting to lock the emplacement when the car is stationary.On coaxial pa rt 7,two bores II are foreseen.The screen rod foresees initial cylindrical part 12 for insertion equipped with bore system 13 and,above it;part J4 with a larger diameter so as its crown 15 hits in composition on the edge of part 7.The stem is fitted with articulation 16 and the subsequent raised part 17 using some further articulation,if required.In particular,the parasol is fo reseen in any possible form,such as round,rectangular,square,hexagonal,octagonal etc.The shadow projection can be adjusted to the type of the screen form used by adapting the number of the scale bore couples foreseen on the insertion body to the one of the parasol sides.In this way,a hexagonal screen could require a scale with six bore couples,permitting thus six positions with slanting rod and a seventh one with vertical stem.For the integral operating clutch,the use of a padlock has been foreseen (I8). Practically, the execution particulars,for which the form of the transversal guides and of the couplings,the emplacement;the rod and the parasol may be differently carried out. Moreover,an employ variety for materials and accessories has be en foreseen.
