Abstract

The invention relates to the stadium seats with overlapped joint. The seat consists of a seat frame-shell (1) which has in the same casting on the lateral sides the attachement for connection with the base in the form of elbows viz. the upper elbow (2) and the bottom elbow (3) overlapping each other so that the bottom elbow (3) undergoes the upper elbow (2) covering the bearings (8, 9, 10, 11) for passage of the bolts (18) jointing the base (19). Such an overlapping joint enables great saving in the number of bolts with anchors when the seats are fitted on large stadiums in the long-series rows. Fitting is fast with no models required. In each row only the first and the last seats under elbows contain masks (14) and (15). The seat back (4) has the front wall (5) and the rear wall (6) so that it is formed in the shape of a box thus contributing to the entire rigidity of the seat. Elbows (2) and (3) contribute to orderly appearance of the rows of seats series because they precisely define the distance between them and the position, and enable strong and firm connection to the base with utilization of twice smaller the number of bolts with anchors and twice less drilling of holes in concrete for the assembly.

Description

STADIUM SEAT WITH OVERLAPPING JOINT

The invention belongs to the domain of outfitting and arrangement of civil engineering projects. It relates first of all to sports stadiums and halls, waiting rooms, railway and bus stations, corridors, etc. and more closely ranks in the domain of furniture, leg-free chairs and seats or stands directly fitted to the base. The invention also belongs to the field of seats made of plastic materials. According to the International Classification of Patents (ICP), designations are as follows: A47C1/16, A47C3/16, and A475/12.

The World Football Federation set forth strict regulations for stadium seats which must be satisfied by the invention, and these include shape, dimensions, and self-extinguishable material as well as absolute safety. In addition, the invention must solve the problem of low price of seats and fitting because a great number of seats on larger stadiums are in question. This seat resolves the problem of a single tool for manufacture of a single-piece seat with back without support with easy, fast, safe and cheap fitting requiring twice smaller the number of bolts and anchors without a possibility of easy undesirable removal.

Well-known designs of such a type of seats are as follows:

Various constructions of metal supports, bracket, plate-like, tubular frames and legs to which plastic seat shells are connected via bolts, and these also by bolts with anchors to the concrete base. Another form of well-known designs reflects in a direct connection of the plastic shell and the base. One well-known example is the seat manufactured by the Italian Manufacturer Venelli, Novanta 2, which is tied to the base by two bolts directly through the seating surface of the seat. In this design, an extra small shearing surface can be seen at the bolt place for the case of aggressive pulling out of the seat. As one well-known design we would

design registered under No. P-263/96 which, in contrast to this xfttir. has a support tied to the base, and the seat shell pulled over the suppufr^" lengthwise the guides locked with the appropriate teeth.

The drawing figures describe more detailedly the invention on an example of the method of execution:

Fig. 1 shows view of the seat from above

Fig. 2 shows the lateral view of the seat with the bottom elbow

Fig. 3 shows the lateral view of the seat with the upper elbow

Fig. 4 shows a detail of the lateral view when the upper and the bottom elbows are in overlapping position, cross-section

Fig. 5 shows the bottom elbow mask

Fig. 6 shows the upper elbow mask

Fig. 7 shows a series of seats with the overlapping joint viewed from above.

The seat for stadiums with the overlapping joint, according to the invention and Fig. 1, consists of a seat shell and lateral elbows 2 and 3. Item 2 is the upper elbow and Item 3 the bottom elbow. The bottom elbow 3 undergoes the upper elbow 2. The seat back 4 is formed as a box and consists of the front wall 5 and the rear wall 6. The opening 7 is planned for water flowing out of the concaved seating surface and is located on the lowest point. Bearings for bolts with anchors 18 of the upper elbow are 8 and 9 while the bearings for bolts of the upper elbow are 10 and 11. The rib 12 is located on the upper elbow and the groove 13 on the bottom elbow.

The bottom elbow mask 14 overlaps the bottom elbow 3 and is located at the end of the upper elbow 2, in the beginning of a series of seats of each row.

Tenons 16 and 17 are placed after the seat assembly has been finished and they form the bolt heads with the opening for key inaccessible to undesirable removal. The tenons are removed similar to a drill for removing the wine plugs. The overlapping joint, according to the invention,

and firm connection between the seat and the base 19 in four seat^ j^ with two bolts per seat, thus achieving great saving on stadiums wttfjTTif large number of seats. At fitting (assembly) no model is required because seats undergo one under the other, and the elbows 2 and 3 define a distance between the seats, the seat step, which is ergonomically defined. After fitting the first seat, the next to it is to be fitted so that the upper elbow 2 of the second seat covers the bottom elbow 3 of the first seat. After that, a concrete base is drilled through the covered bolt openings in the bearings 8, 9, 10 and 1 1, and the bolts with anchors knocked in these openings. Thus the seat is fitted and fixed to the base by a simple and fast procedure. The seat shell 1 includes in one casting the seat back 4 consisting of the front wall 5 and the rear wall 6, as well as the lateral overlaps in the form of elbows 2 and 3 on which are located the bearings for bolts 8, 9, 10 and 11. The rib 12 and the groove 13 for stiffening purposes are located on elbows. Special components, castings also made of plastics, are the masks 14 and 15, as well as tenons 16 and 17. The opening 10 for connecting the bolt is in the form of a slit so that every seat could be turned a little bit as stadiums are constructed in the form of archs with big radius. According to the invention, with such a design of the seat-base joint, a compact and safe connection resistant to pulling out and tearing out has been achieved, as well as orderly arrangement of a series of seats in each row with the uniform step and cheap assembly.

Claims
