This application claims priority under 35 U.S.C. § 119 and 37 C.F.R. 1.55 to Spanish Patent Application No. P201830335, filed Apr. 4, 2018, which is incorporated herein by reference.
The present invention relates to the seats which are arranged in venues in a movable way in order to enable the seats to be adapted depending on the activities to be held in the venue, the invention proposing a mobile support for the seats, with which advantages are achieved, both in the installation and the positioning of the seats.
There are venues intended to be used occasionally for different activities, such that in some cases it is required that the surface be free of obstacles, for example, for playing sports, while in other cases an arrangement of chairs is required in order to be occupied by spectators or attendees of a show, conference or similar event; which requires said venues to be able to be transformed by arranging and removing chairs.
To do so, the most traditional solution is the use of chairs, generally folding, which are placed and removed depending on the event to be held, this practice being very laborious due to the work that the placement and removal of the chairs requires, as well as the storage thereof, in addition to the fact that the chairs used in these cases are not very comfortable.
Consequently, solutions for installing seats by means of mobile assembly systems have been developed, such that the seats can be moved between a collected position in storage, leaving the surface of the venue free, and an unfolded position wherein the seats are distributed in the venue in order to be used. See for example documents EP1864593B1, EP2014194B1 of the same applicant as the present invention.
However, in these conventional solutions, the seats are arranged on moving guides, which requires a complex installation, due to the necessary incorporation of the guides for moving the seats on the floor of the venue and of the means necessary for covering the guides when the floor needs to be left free for other activities.
Moreover, in those conventional solutions, in order for the seats to remain stable in the position of use thereof, locking solutions are needed which act together with the movement means, which complicates the embodiment of the movement means.
Accordingly, a solution is needed to quickly deploy seats at a venue and efficiently storage them in a compact arrangement.
The invention relates to a mobile support for seats. Accordingly, this disclosure provides a mobile support for seats (1), comprising a support bar (2) for the seats (1) which has feet (3) for resting and moving on a floor (4) of the installation site of the seats (1), wherein each foot (3) comprises a casing (5) which in the lower portion incorporates anti-slip blocks (6), while inside of said casing (5) an articulated structure (7) is arranged provided with wheels (8) which can tilt between an upper position wherein they stay above the bearing level of the anti-slip blocks (6) and a lower position wherein the wheels (8) stay with a bearing point below the bearing level of the anti-slip blocks (6) for a movement by rolling on the ground (4).
The following drawings form part of the specification and are included to further demonstrate certain embodiments or various aspects of the invention. In some instances, embodiments of the invention can be best understood by referring to the accompanying drawings in combination with the detailed description presented herein. The description and accompanying drawings may highlight a certain specific example, or a certain aspect of the invention. However, one skilled in the art will understand that portions of the example or aspect may be used in combination with other examples or aspects of the invention.
According to the present invention, a mobile support for seats is proposed which comprises a support beam for the seats, the support beam being incorporated on movable feet on the floor of the installation site of the seats, obtaining with the mobile support of the invention characteristics which improve the function of the mobility of the seats, while simplifying the practical assembly and the installation cost.
The foot comprises a casing which in the lower portion is provided with anti-slip blocks for resting on the floor, an articulated structure carrying wheels being housed in the casing and which can tilt between an upper position wherein the bearing point thereof is above the bearing level of the anti-slip blocks and a lower position wherein the bearing point of said wheels is below the bearing level of the anti-slip blocks.
Thus, a foot is obtained which enables, by means of tilting the wheels, it to rest in a rolling manner in order to move the seats, or rest in a fixed manner with the anti-slip blocks, in order to leave the seats static and stable in the placement site; without sliding guides for the movements or locking means to ensure the static positioning being necessary for that purpose.
According to one embodiment, the articulated structure wherein the wheels are incorporated is made up of two connecting rods, each one provided with, at least, one wheel, said connecting rods being joined in a joint to the casing of the foot and connected to each other by means of a brace, while one of the connecting rods has a bushing wherein a lever bar can fit to actuate a change in position of the articulated structure between the upper and lower placement positions of the wheels.
In this way it results in an embodiment that is very simple and can be easily actuated for arranging the foot in the movement position and in the static position for the mobility and anchoring of the seats in the installation sites.
Preferably, the joint between each foot and the support bar is established by means of a rotating coupling which enables the directional orientation of the foot for the movements.
The coupling of the foot with respect to the support beam of the seats is foreseen as being made up of a vertical tubular housing incorporated in the upper portion of the casing of the foot and a corresponding cylindrical rod incorporated in the lower portion of the support beam of the seats, with horizontal contact surfaces between both portions, between which at least one elastic ball lock is included which enables the anchoring to be ensured between said surfaces in several relative rotation positions therebetween.
Thus, an embodiment is obtained which is simple and can be easily handled to adapt the foot to different movement directions, enabling the seats to be easily moved to the sites of interest in the installation.
In light of this, the support of the invention results in characteristics which are very advantageous for the application for which it is intended, taking on a life of its own and preferred character with respect to conventional solutions with the same function.
