Description

Technical Field of the Invention

[0001] The invention relates to a reinforced stadium seat which is mounted in the vertical surface (riser) between two steps in concrete floor steps used in indoor and outdoor sports halls, stadiums and similar places; which is formed in compliance with human anatomy; the metal components of which are designed as one-piece by laser cutting and bending operations in press dies, said metal components also serving as a mechanism and interconnecting the seat and back support plastics; the strength of which is quite high due to the lack of welding operation; and at the same time the durability of which is increased with the concealed transmission rods positioned within the seat and back support plastics.

Background of the Invention (Prior Art)

[0002] Today, stadium seats are used in outdoor or indoor sports halls, stadiums, etc. in order for the spectators to watch the events. It is desired that these seats are easy to mount in halls and stadiums, their design is suitable for the body shape, the seats are closed when not in use, and that they are durable in order to increase the service life thereof.

[0003] During the mounting of the seats used in the state of the art in halls, stadiums, and similar areas, the parts connecting the seat and back support portions are welded together for mounting, which increases the costs, causes losses of space during transport since the parts to be welded are carried separately, and at the same time leading to increases in the cost due to the welding operation and dyeing costs during the production phase of the seat.

[0004] Again, due to the fact that the parts connecting the seat and back support portions are welded together and that the seating surface is stable, the service life of the seats is reduced in case of setting foot or mounting on the seat portions and cracking and breaking occur in welding areas over time.

[0005] Moreover, the seat portions get either wet or dirty in bad weather conditions due to the seat portion being open. This, in turn, causes the users to watch the events standing.

[0006] In hot or other weather conditions, the spectators sweat a lot because they are very active during the events. As the backrest and seat portions of the seat are typically flat, sweating is experienced more in the regions where the spectators contact with the seat while the spectators are sitting on the seat. Even in the absence of sweating, the spectators start to slide over the seat after some time and have difficulty in watching the game because of the little friction between the spectator and the seat in case of seats with flat backrest and seat portions.

[0007] In order to eliminate the aforementioned drawbacks, it has deemed necessary to make a development in the related technical field due to the fact that the part connecting the back support and seat portions is not one-piece, i.e. weldless, and hence welding operation is required, and that it is not produced for folding seats.

Objects and Brief Description of the Invention

[0008] The present invention relates to a reinforced stadium seat which can be used in outdoor-indoor sports halls and stadiums and which meets the aforementioned requirements, eliminates the drawbacks, and at the same time provides additional advantages.

[0009] An object of the invention is to form the seat which is mounted in the concrete floor in outdoor-indoor sports halls, stadiums and similar places such that the connection part which connects the seat and back support portions of the seat is obtained as one-piece by forming by means of cutting and bending operations, and to provide a self-folding system with high strength as welding operation is not performed.

[0010] Another object of the invention is to save on costs and labor by forming the back support portion of the seat as one-piece by cutting and bending operations, and hence eliminating the welding operation as well as the dyeing costs in the production phase of the seat.

[0011] Still another object of the invention is to eliminate weld cracks and breaking that may result therefrom which are experienced over time in welding areas due to reasons such as mounting on the seat portions or applying force thereon owing to the fact that the seat-back support connection part is produced as one-piece by forming by means of cutting and bending operations, and thus the welding operation is not performed during the production phase of the seat.

[0012] Another object of the invention is to increase the movement areas of the spectators with the seat portion closing and the seat folding upon the users standing up from their seats, by way of the weight rod disposed in the weight rod space of the seat portion.

[0013] Yet another object of the invention is to ensure, by means of the weight rod disposed in the seat portion, that the seat portion closes by itself upon the users standing up from their seats, i.e. when the seats are not in use, and hence the seat portions of the seats remain clean and usable in bad weather conditions.

[0014] Another object of the invention is to increase the strength of the seat portion by way of the transmission rods concealed in the seat portion.

[0015] Another object of the invention is to increase the strength of the back support portion by way of the one-piece connection plate concealed in the back support portion.

[0016] Yet another object of the invention is to provide the weldless one-piece plate, which serves as a mechanism, with caps produced of Polypropylene (PP) material in order to prevent jammed fingers while the users sit on/stand up from their seats.

[0017] Another object of the invention is to connect the weldless one-piece plate of the seats directly to the riser without requiring the use of any other material.

[0018] And another object of the invention is to easily mount the weldless one-piece plate of the seats on the cross members to be produced. These cross members reduce the number of concrete inserts in stadium precast and prevent concrete weakening, at the same time facilitating the replacement of the seats in future.

[0021] In this detailed description of the invention, the preferred embodiments of the stadium seat having been developed herein are described only for a better understanding of the subject matter, without any limitations.

[0022] The stadium seat mainly comprises a seat portion (1), a back support portion (2), a weldless seat-back support connection plate (3) providing the connection between the seat portion (1) and the back support portion (2), and transmission rods (5) which are positioned within the seat portion (1) for reinforcing the same.

[0023] The seat-back support connection plate (3) has a single piece (weldless and one-piece) configuration formed by cutting and bending operation.

[0024] The seat-back support connection plate (3) is connected to the back support portion (2) by extending towards the upper portion, and to the seat portion (1) by extending towards the front.

[0025] The sides of the seat portion (1) are provided with the seat connection plate (6) extending along the seat portion (1) and having the same form. The seat connection plate (6) is coupled to the seat portion (1) by means of the connecting bolts and nut.

[0026] The seat portion (1) is provided therein with transmission rods (5) which are positioned for reinforcing purposes. The transmission rods are not visible from the outside. The transmission rods (5) are positioned along the seating portion of the seat portion (1) and secured by means of the nut (13) by passing the locking bolts (12) through the holes disposed in the seat connection plate (6).

[0027] Disposed within the seat portion (1) is a weight rod (7) which ensures that the seat is folded upon the spectator standing up from the seat portion (1) surface. The weight rod (7) used for ensuring that the seat portion (1) assumes folded position when the spectator stands up from the seat portion (1) is located in the weight rod space (8) subsequent to the injection operation of the seat portion (1) during the production phase of the seat. The weight rod (7) may be metal or any other material.

[0028] The end portion of the seat-back support connection plate (3) extending towards the seat portion (1) is provided with an oval seat movement pin housing (3.5) that enables seat portion (1) to move up and down. The seat movement pin (10) moves inside the seat movement pin housing (3.5), thereby ensuring the up and down movement of the seat portion (1). The end portion of the seat movement pin (10), on the other hand, is provided with an anti-noise assembly. Said anti-noise assembly is produced of rubber or a similar material. The seat movement pin (10) which moves inside the seat movement pin housing (3.5) hits the boundaries of the seat movement pin housing (3.5) during the up and down movement of the seat portion (1). The anti-noise assembly is located in the end portion of the seat movement pin (10) with a view to prevent the noise likely to be heard during this hitting.

[0029] The portion of the seat-back support connection plate (3) towards the seat portion (1) is provided with a protective cap (11) in order that the seat movement pin (10) can operate easily and it will not cause any accident. Said protective caps (11) are made of polypropylene.

[0030] While the up and down (unfolding-folding) movement of the seat portion (1) is ensured by the seat movement pin (10) disposed in the seat movement pin housing (3.5), there also exists a seat centering pin (9) that prevents the horizontal movement of the seat portion (1). The seat centering pin (9) is passed through the seat centering pin housing (3.5) and then the seat-back support connection plate (3) and the seat portion (1) are secured together.

• a seat centering pin housing (3.4) through which the seat centering pin (9) interconnecting the back support connection plate (3) and the seat portion (1) passes, and
• a seat movement pin housing in which the seat movement pin (10) moves while the seat portion switches from unfolded position to folded position, or from folded position to unfolded position.

[0032] In an embodiment of the invention, a riser connection mechanism (4) has been developed in order to secure the stadium seat to where it is.

[0033] The riser connection mechanism (4) consists of:

• a riser connection cross member (4.1) on which the seat-back support connection plate (3) is positioned,
• riser connection cross member caps (4.3) that are disposed at both sides of the riser connection cross member (4.1) profile,
• a riser mounting bracket (4.2) which is welded or otherwise joined in the middle portion of the riser connection cross member (4.1), and
• a riser connection plate (4.4) on which one end of the riser mounting bracket is welded and which is mounted on the riser by way of bolts (12) and nut (13).

[0034] Provided at the lower portion of the seat portion (1) is a numbering area (14). Numbers, e.g. 1, 2, 3, are adhered to this area, and thus allowing the spectators to easily find their seats.

[0035] Riser connections cross member caps (4.3), on the other hand, are provided thereon with a lettering area (15). Letters, e.g. A, B, C, are adhered onto the riser connection cross member caps (4.3), and thus allowing the spectators to easily find their seats in the stadium.
