WINDING DEVICE FOR BILLIARD TABLE COVERS
The present invention relates to covers for covering and protecting billiard tables. Billiard tables, when they are not used, must be covered with a dust protection cover.
The covers which are currently used require the mounting of fixing parts on the shoulders of the billiard table and are also somewhat difficult to fit. Moreover, the covers must be stowed away when the billiard table is uncovered for use.
The object of the present invention, therefore, is to provide a winding device for winding up and unwinding the cover for billiard tables, which can be easily and quickly fitted to any billiard table without having to mount screws or other retaining means on the shoulders of the said tables, allows rapid covering and/or equally rapid uncovering of the billiard table and keeps the cover always properly tensioned and tightly against the shoulders of the billiard table itself.
Further objects and characteristic features of the device according to the present invention will become clear from the following description of a number of preferred embodiments thereof illustrated by way of a non-limiting example in the accompanying drawings in which:
Figure 1 is a cross-sectional view, along the plane passing along the line l-l in Figure 2, of one end of the playing surface with corresponding shoulders of a billiard table, with a winding device mounted according to a first embodiment of the invention;
Figure 2 is a view, with parts cross-sectioned, of a side of the billiard table shown in Figure 1 ; Figure 3 shows a detail of a billiard table according to a modified embodiment of the present invention with, mounted, a winding device incorporated in the table itself; and
Figure 4 is a detail of the shoulder which is situated at the opposite end to the end where the winding device of the billiard tables according to Figures 1 and 3 is mounted, showing the device for fastening the free end of the said cover.
With reference to Figures 1 and 2, the billiard table shown comprises the playing surface 1 supported by the legs 2 and surrounded by the two side shoulders 3 and 3' and by the two end shoulders 4 and 4'.
5 denotes the device for winding up the cover 6. This device comprises two side members 7 with an L-shaped cross section in profile supporting between them the shaft 8 of the drum 9 for winding up the cover 6. This drum 9 is provided internally, in an entirely conventional manner, with a spring device (not shown) for automatically rewinding the cover 6. A plate 10 is connected to each end of the legs T of the side members 7, directed towards the inside of the billiard table, said plate 10 being provided with two threaded holes 11 inside which the threaded shanks 13 of two clamps 12 are screwed. A head piece 14 is connected, via a hinged joint, to the end of the shanks 13 directed towards the outside of the table, the shank 13 being provided at the other end with an operating head 15 for screwing in the threaded shanks 13.
The cover 6 has at its free end a locking bar 6'" which co-operates with stops (not shown) for the purposes which will be described below and also has a terminal stiffening strip 6' provided with eyelets 6", while the shoulder 4' at the end opposite to the end 4 where the winder 5 is mounted has on its free edge a pair of hooks 16 with an L-shaped cross section in profile (shown more clearly in Figure 4) able to be rotated from a position where they are contained inside the shoulder 4' (position shown in broken lines in Figure 4) to a position where they project with their free end beyond the shoulder 4' (position shown in continuous lines in Figures 2 to 4).
The operating principle of the device described will become clear below.
In order to fit the cover-winding device to the billiard table, the device 5 is inserted between the two side shoulders 3,3' of the billiard table, close to one end of the said table, and by operating the operating heads 15 connected to the threaded shanks 13 of the clamps 12 the head pieces 14 are pushed tight against the inner side of the shoulders 3, 3' so as to fix firmly the device 5 against the billiard table. At this point, the end 6' of the cover, which is kept projecting from the winding drum owing to the action of the bar 6'" co-operating with suitable stops, is gripped and is passed upwards beyond the outer side of the shoulder 4 and then stretched over the surface 1 and over the upper side shoulders V and the end shoulders 1 " and finally is pulled downwards along the other end shoulder 4', where the eyelets 6" are engaged by the hooks 16 which have been pivoted into the position shown in continuous lines in Figures 2 and 4. Obviously, in order to uncover the billiard table, the operations described are repeated in the opposite sequence.
Figure 3 shows a variant of the device according to the invention. Identical or corresponding parts are indicated by the same reference numbers used in the description of the embodiment according to Figures 1 , 2 and 4.
According to this variant the winding device 5 is incorporated stably inside the table itself. For this purpose, the winding device 5 is mounted on a support 105 which is fixed by means of screws 205 to the surface of a leg 2 of the table directed towards one end of the said table. This support 105 is provided with a pair of side arms 305 which project forwards in the manner of a bracket towards the end shoulders 104 and which support a drive roller 405 at a short distance from this shoulder. An upwardly inclined slit 204 is formed in the shoulder 104. The cover 6 which is unwound from the winding drum 9 of the device 5 is passed around the drive roller 405 and directed upwards through the slit 204 of the shoulder 104 beyond which it projects with the terminal gripping part 6' which is kept suitably parallel to the outer side of the shoulder 104 by means of a Velcro-type (or similar) fixing part 304. The stop 6'" prevents the terminal part 6' of the cover from passing beyond the slit 204. The operating principle of the device described is entirely similar to that described with reference to the previous embodiment.
Obviously the present invention is not limited to the embodiments shown and described, which are provided solely by way of a non-limiting example of a number of possible embodiments of the present invention, but comprises all those variants and modifications made to a winding device for a protective cover for billiard tables, substantially as claimed below and for the objects mentioned above. Obviously, the cover 6 may be made of any material suitable for this purpose, for example non- woven fabric or the like. Advantageously, this cover may bear printed information advertising the model of billiard table which is covered or adverts for various products. Moreover, although means for hooking the gripping end of the cover 6 onto the shoulder 4' of the table have been described, it is understood that these hooking means may be replaced by means of a Velcro fastening system with co- operating parts.
