MOBILE BANK FOR ARMCHAIRS

DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a bench for seats, which has the special feature of having two operating positions, one in which the bench is stable, to work in an operating or storage position, and another in which the bench is movable by means of a set of retractable wheels that allows the benches that participate in the rows of seats to be moved so that they can be removed and stored occupying a minimum space and thus leaving a large area of the seats patio diaphanous so that it can be used for other purposes .

The object of the invention is therefore to provide a mobile bench that can be easily displaced and that in an operating situation is totally stable.

BACKGROUND OF THE INVENTION

In certain rooms or courtyards, it is common for said surface to be used for different types of events or events, so that sometimes a clear space is required, for which it is necessary to remove the seats installed on said surface .

Although there are benches for rows of seats sufficiently stable so that they do not have to be screwed to the ground, and consequently they can be displaced, they do not have means to facilitate such displacement, which makes them have to be lifted by hand with the consequent risk of injury due to overexertion.

DESCRIPTION OF THE INVENTION

The mobile bench for seats that is recommended solves in a completely satisfactory way the problem previously exposed, based on a simple but effective solution.

To do this, based on the conventional structuring of this type of benches, in which a main horizontal beam is defined to which a series of seats are fixed, with its corresponding seat and folding armrests, beam that is inferiorly linked to the At least one pair of support bases on the ground by way of shoes, the bed of the invention has the particularity that said support bases or shoes have a hollow character, in which a retractable tread system for the bench is established.

More specifically, it is envisaged that the lower face and of contact with the floor of the housing of the support base includes a series of holes through which it is possible to make wheels emerge that significantly facilitate the movement of the assembly for give it a mobile character, but totally stable when the wheels are picked up.

To do this, the wheels are linked to an internal platform, vertically movable within the aforementioned shoe.

Said vertical displacement is made through a tubular guide of coincident section with a central hole made in said internal platform.

The tubular guide externally has torn holes that act as elements that determine the upper and lower limit displacement of the wheel carrier platform.

For this, the wheel-bearing platform is linked to an internal prismatic piece of section according to the internal section of the tubular guide through rods through the torn holes and linking both pieces.

Between the internal prismatic part established in the vertical tubular guide and the lower face of the shoe casing, a spring is established that tends at all times to said piece and consequently to the platform carrying the wheels to the slapping situation, it is tell the stable rest situation for the bench, a situation that coincides with the upper limit of the torn grooves of the vertical tubular guide.

In said tubular guide, internally and superiorly an eccentric cam is established whose surface rests on the prismatic part, so that depending on the rotation of the eccentric, the relative vertical position of said prismatic part is varied between the upper and lower limits that determine the torn holes of the vertical tubular guide, and that coincide with the position of maximum extraction of the wheels and of total retramoteo of the same.

Finally, the axis of the eccentric cam is associated with a horizontal rod, which will be externally accessible either through the horizontal beam of the bench or the shoe itself.

In this way, by means of a simple key, it is possible to act externally on the eccentric, to cause the thrust in the lower direction on the prismatic part linked to the wheel carrier platform and to obtain the extraction of these to facilitate the movement of the seats for storage or distribution on the surface or patio of seats in question, and when they are arranged in the intended area, it will be enough to act with the aforementioned key in the opposite direction so that the wheels are collected and the bench bearing the Armchairs are perfectly stabilized to the ground through their shoes.

As is evident, the number of wheels used and their distribution may vary without affecting the essence of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the bed of the invention is constituted from a main horizontal beam (1) to which a series of seats (2) are fixed, with its corresponding seat (3). and folding armrests (4), and which is inferiorly linked with at least one pair of shoes (5) of stable support on the ground.

Well, according to the invention, the shoes (5) will have a hollow character, counting in its lower face (6) with holes (7) through which it is possible to make self-orientating wheels emerge (8) associated to a platform (9).

As shown in Figure 9, the platform (9) has a central hole (10) coinciding with the outer section of a tubular guide (11) through which it is vertically movable, tubular guide (11) having holes Torn (12) that act as elements that determine the upper and lower limit displacement of the platform (9) carrying the wheels (8).

Said displacement is determined by the internal displacement within the tubular guide (11) of a prismatic part (13) of section according to the section of the tubular guide (11), and which is linked to the platform (9) to through rods (14) that play in the torn holes (12).

Between the internal prismatic part (13) established in the vertical tubular guide and the lower face (6) of the shoe casing, at least one spring (15) is established, which makes said part at all times and consequent to the platform (9) carrier of the wheels (8) to the sneak situation.

In addition to the tubular guide (11), an eccentric cam (16) is provided that rests on the prismatic part, so that depending on the rotation of the eccentric (16), the relative vertical position of said prismatic part (13) is varied. between the upper and lower limits that determine the torn holes (12) and that coincide with the position of maximum extraction of the wheels and of the total skidding thereof.

The eccentric cam (16) is associated through its axis of rotation (17) to a horizontal rod, topped on a thyme head (18) that will be externally accessible, as shown in Figures 2 and 5, a through a drive key (19).

5 Consequently, when acting externally on the screw head (18) with the actuation key (19), it will be possible to cause the self-steering wheels (8) to be extracted or retracted, and consequently to ensure the stability of the assembly, or where appropriate , facilitate its mobilization.
