Description

Removable fixing mechanism for seats.

Object of the invention

The present invention relates to a mechanism intended for fixing seats to the floor, seats of the used in theaters, auditoriums and the like, where eventually it is necessary to assemble or disassemble them, as per example to enlarge the scenario, enable a zone for a orchestra, etc.

The object of the invention is to achieve a mechanism that allows the solid fixing of said seats to the ground and easy disassembly of them when necessary temporary withdrawal

It is also the object of the invention to achieve that said assembly / disassembly, in addition to being extraordinarily fast and simple, do not involve less deterioration for the media Anchoring the armchair, nor for it as a whole.

Background of the invention

In certain public establishments, such as the theaters and auditoriums mentioned above, depending on the characteristics of the show, you can take advantage the entire patio of seats, as an area for spectators or on certain occasions it may be necessary remove some of the front rows of seats to enlarge the useful area of the stage, to arrange or increase the area corresponding to the orchestra, etc.

Usually the seats are fixed to the floor by screwing, so that when for any reason it it is necessary to disassemble these seats should proceed to loosening and total extraction of the nuts, to release the armchair, which is a slow and laborious task, which can extend for a considerable period of time if the number of seats to disassemble is important, with the consequent and negative impact that this brings with it at cost level, due to the considerable amount of labor that is necessary for this operation and for its subsequent and new assembly.

When, as usual, threaded stems they are implanted in the ground, they cross the legs or supports of the armchair, and receive the corresponding nuts, as it happens usually, an additional problem arises, and that is that after the seat elimination threaded stems protrude notably from the ground, constituting obstacles that hinder the use of the space that was left free when the seats were removed, and that they can even become dangerous for people who have to wander around this area.

Description of the invention

The mechanism proposed by the invention resolves in a fully satisfactory way the problem previously exposed, in the different aspects commented.

To do this, more specifically and in agreement with one of the characteristics of the invention, the device that It is recommended to consist of a kind of taco, intended for implant in the ground and be flush with it, hollow and equipped at its upper base with a diametral groove, intended for receive the transverse branch of an inverted "T" fixator, destined to cross the corresponding leg of the armchair and equipped of fixing means to the latter.

According to another of the characteristics of the invention the fixing means of the fixator to the armchair leg they consist of an eccentric, provided with a drive arm, which attaches to the upper end of the fixator through thread, to be able to vary at will your distance with respect to the cross branch of the fixator itself, in order to adapt the armchair mechanism with different thicknesses in its leg, act said eccentric on the leg with interposition of a ring lowered, whose recess constitutes a perfectly adjusted seat to  the surface of the cam or eccentric.

Finally and according to another of the characteristics of the invention, within the block, provided in its bottom base of a hole for fixing by thread to bottom floor housing, incorporates a washer over the that acts a spring that works under compression, and that tends to press the transverse branch of the fixator against the upper base from the taco itself.

According to this structuring and once coupled the mechanism to the armchair leg, just position conveniently the fixer, as far as its angular position is refers, acting laterally on the eccentric arm until the transverse branch of said fixer is perfectly facing the groove of the upper and outer heel base, moment in which said fixer penetrates inside the block and, supplying a new rotating movement, preferably 90 ° a through a horizontal movement of said arm, both elements, fixator and block, are interrelated, being carried out definitive fixation by vertical arm tilting, with the consequent turn of the eccentric and tighten through the ring lowered the arm's leg against the heel or what is it Same, against the ground.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to an overview in perspective, a removable fixing mechanism for seats performed in accordance with the object of the present invention.

Figure 2.- Shows, according to an elevation view lateral and in section, the same mechanism of the previous figure in working situation, that is, fixing the corresponding ground seat.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the mechanism that is recommended is constituted to from a taco or base body (1), which can adopt the cylindrical configuration of the figures or any other that deem convenient, hollow block, open bottom, where closing with the collaboration of a practicable cover (2), preferably by means of a thread coupling, presenting said block in its upper base (3) a diametral groove (4) intended to allow the passage of a configuration fixer (5) in "T", specifically to allow the cross-sectional passage (6) of the latter, so that in a certain position angle for the fixer (5) it can enter and exit freely of the block or base body (1), while in any other position rotated with respect to the previous one, preferably with a lag of  90 ° with respect to the groove (4), determines a fixation of the fixator (5) with respect to the block (1), as shown in Figure 1.

This fixative (5) is topped by its tip upper and free (7) in a threaded section (8) through which relates to a transverse axis (9) to which a eccentric (10), in the example of practical realization of figures an eccentric double based on two lateral cams (10-10 ') that frame the fixative (5), being said eccentric (10-10 ') integral to a lateral arm (11) which allows it to be tilted in the direction of rotation with respect to the fixator (5) to change the position of the branch transverse (6) with respect to the groove (4), or with respect to its own shaft (9) to press a complementary ring (12) mounted on the fixator itself (5), against the leg (13) of the armchair, and press said leg against the ground (14).

The aforementioned ring (12) has a recess ribbed (15) in its face facing the eccentric (10-10 ') for a perfect settlement of this Last, as seen in any of the figures.

As a complement to the structure described in the sine of the base body or block (1) a spring or spring is established (16), which works under compression, resting on the lower cover (2) of the block (1) and through a washer (17) press the transverse branch (6) of the fixator (5) against the upper base (3) of the taco itself, or tends to eject said transverse branch (6) to outside when properly facing the groove (4).

It only remains to note that, as note in figure 2, the block or base body (1) is intended for embedded in a housing (18) on the ground (14), and fixed to the fund of said accommodation with the collaboration of a screwdriver (19) that passes through the cover (2) through a central hole (20) of this last, incorporating the washer (17) another axial hole (21) to allow the passage of a screwdriver acting on said screws (19).

It is thus achieved that the armchair is extraordinarily quick and easy to assemble since it is sufficient to conveniently face the transverse branch (6) of the fastener (5) to the groove (4) of the block (1), to provide said fixator with a turn partial of 90 ° for its offset with respect to said groove, acting on the arm or lever (11), and finally tilting said lever (11) down so that the eccentric (10-10 ') definitively blocks the mechanism in situation of solid mooring of the armchair
ground.
