Definitions

• This invention consist of a set for the assembling of lift doors and of a transporting carnage that occupies a smaller room than the conventional ones, on the wall placed above the bay, it refers too to a door transporting carriage that, assembled into that set, can be adapted to doors of different measures, makes easier its assembling and mounting and permits to carry out the adjustments and regulations with great facility
• the building lifts have a cabin which shifts upwards and downwards through the lift shaft which in each floor has a bay with floor doors
• doors are mounted on transporting carnages which shift on guide bars that bear a rail in the middle and are usually placed facing the vertical hole, on the small piece of wall that is between the top of the bay and the level of the upper floor
• the conventional devices known at present need a special place for the blocking assembly (the hook, that slides together with the doors) and besides an additional room to mount other parts, e g the safety electrical contacts Due to this, the total height of the device is too much with respect to the room that exists above the bay This makes necessary to reduce the height of the rail or of the guide bar where the carriages that carry the doors run The result is that the rail turns to be a structurally weaker element
• an additional profile is installed which is a complement of the existing rail, with the corresponding addition of costs and time wasting
• the conventional transporting carriages they consist of a fixed assemblage on which the wheels are mounted
• the manufacturer must have carriages to cover different measures, according to the measure of the door they are going to be applied
• the existing carriages have their door mounting side facing the bay, which originates that the assembling operations must be done within the tiny room delimited by the wall beside the said bay with the additional complication that certain assembling pieces must be mounted from the opposite side, that is, behind the carnage
• Another common difficulty is that the accuracy in assembling previous to the doors mounting, must be corrected by means of regulations the said mounting, which means a waste of time.
• An additional restriction of the conventional systems is that, in the case of fire, to avoid the fall of the doors and the consequent propagation of the fire through the bay, they require an additional hooking means, which must be added to the doors transporting carriage structure.
• the purpose of the present invention is to provide a set for the assembling of lift doors that, on the wall placed above the bay, occupies a smaller room than that of the conventional sets due to the fact that it bears a guiding means open lengthwise for the running of the blocking device.
• the present invention refers too to a lift doors transporting carriage with an extensible assemblage which can be adapted to doors of different measures, and with rolling basis which make unlevelled supports, what constitutes a facility for the assembling and mounting and permits to make adjustments and regulations.
• the guiding means of the present invention consists of an open profile or rail, inside which are placed the electrical contacts and the opening permits the shifting of the blocking device or hook inside the guiding means.
• an advantage is that its assemblage is extensible, formed by rolling basis fixed through a joining means supplied with position regulation means. This permits to extend or contract the assemblage to adapt it to different width doors. The use of the same pieces for carriages of different measures contributes to reduce the production costs.
• a fundamental advantage is given by the unlevelled support placed in the lower part of the principal vertical wall of each rolling basis. This makes easier toe assembly not only in the workshop but in the building itself because the doors can be mounted simply by leaning the connecting auxiliary piece on the said unlevelled support.
• the conecting and regulation means are placed on the side of the lift shaft from where, if necessary, it is possible to work much more comfortably than in conventional systems where the mentioned means are placed on the other side, that is, on the side of the wall above the bay where the room is very reduced.
• the existence of an auxiliary connecting piece between the unlevelled support and the door gives the possibility to mount the door leaves with no need of regulation using the fixed connecting means, in case the elements employed in this process have been manufactured and mounted correctly. If, by any case, there had been a mistake during these processes, it can be corrected using the adjustable connecting means.
• the principal advantage of this system is the saving of time employed in regulation when the job has been done correctly.
• the transporting carriage mentioned is apt to bear fire safety devices, as, for example, a hooking piece with the carriage mounting guide.
• This hook is formed by the interconnection means between the rolling basis and it keeps unhooked from the guide by the presence of the carriage plastic wheels which, on burning, melt, producing the hooking that avoids the fall of the doors leaves.
• Drawing 1 is a perspective view that permits to observe the form of the guiding means of mounting and putting on track, as well as the blocking and electrical safety devices inside it.
• Drawing 2 is a perspective view in which can be seen the present set and the small room it occupies on the wall between the bay and the upper floor level. Also the transporting carriage can be seen in this drawing.
• Drawing 3 is a perspective view that corresponds to the transporting carriage different pieces.
• Drawing 4 is a rear elevation view of the transporting carriage in which can be seen the regulation means of the interconnection piece between the two rolling basis. At the bottom of the second rolling basis the auxiliary piece of connection with the door can be seen.
• drawing 1 can be observed the present set for the assembling of lift doors which guiding means (a) is destined to the mounting and putting on the track of the transporting carriages (b) of the doors (d).
• This guiding means (a) is fixed to the wall (8) adjacent to the upper part of a bay (a) corresponding to a landing door, although it is apt too to be applied to the cabin bay.
• the guiding means (a) of mounting and putting on the track of the carriages (b) consists of a lengthwise profile (1) which back wall (2) is closed and its front part is open.
• the closed back wall (2) of the profile (1) is externally linked to the mounting means which connect the profile (1) to the building wall (8) placed between the application bay top (9) and the upper floor level (10).
• the front part of the above mentioned lengthwise profile (1) is open due to the fact that is furrowed by an opening or longitudinal passage (3).
• the electrical safety device (5) On its side, the electrical safety device (5) consists of an electrical switch placed within the limits of the profile (1), more precisely, fixed to the interior surface of the back wall (2).
• the present way of execution does not exclude other ways.
• the guiding means (a) of mounting and putting on the track is formed by two profiles close one from the other and parallel mounted. These, are separated in a measure at least equivalent to the diameter of the axis (7) of the blocking device (6) provided by the carriage (b), and delimit an open cavity in which interior is the electrical safety device (5).
• the condition always is the presence of an opening or longitudinal passage (3) of motion of the blocking device (6) and that the electrical safety means (5) is placed within the limits of the guiding means (a) of mounting and putting on the track.
• the guiding means (a) which bears mounted a transporting carriage (b) includes a rolling assemblage (c) that, in the present way of performance, consists of a train of two rolling basis (e) (f).
• Each one of these rolling basis - first (e) and second (f) rolling basis - has a principal vertical body(11) in which is mounted a wheels set (20) which sliding track is constituted by the guiding means (a) of mounting and shifting.
• the rolling basis (e) (f) presents a lower folding (15) which affects its principal body (11) in a way that results unlevelled (12) respect to the principal body (11).
• This fall (12) constitutes a support destined to the respective door (d) mounting.
• the unlevelled support (12) is placed in an intermediate position between the transporting carriage (b) assemblage (c) and the application bay. (9). More precisely, the unlevelled support (12) includes a vertical wall placed between the plane of the principal vertical wall (11) of the respective rolling basis (e) (f) and the plane that contains the bay (9) and the adjacent wall(8).
• the opening or longitudinal passage (3) of the guiding means (a) permits the sliding of the blocking device (6) which shifts together with the transporting carriage (b) on which it is mounted.
• the disposition of the safety electrical means (5) within the limits of the profile (1) permits all the set to occupy a reduced place on the wall (8) situated between the bay (9) and the level of the upper floor (10).
• the extensible rolling assemblage (c) is formed by a train with two rolling basis (e) (f) linked through a connecting means (13) provided with regulating means (14).
• the length of the assemblage (c) can be extended or contracted withdrawing or approaching the rolling basis (e) (f) one with the other. This allows to adapt the carriage to different doors (d) widths.
• the unlevelled support (12) for the door slants the guiding means or mounting guide
• connection and regulating (18) (19) means project themselves and remain exposed in a position opposite to the wall (8) and the bay (9) - that is , facing the shaft by which the cabin shifts - the regulation and adjustment operations can be comfortably done from that side.
• the presence of the unlevelled support (12) facilitates the door (d) mounting too, by the simple leaning against the transporting carriage (b), when the mounting of the assembly is done before the mounting in the bay (9).
• the assemblage (c) of the mentioned transporting carriage bears fire safety means.
• the assemblage (c) On the same side where the wheels (20), manufactured in plastic, are mounted, the assemblage (c) has a fixing means - a folding or fringe formed by the connection means (13).
• the connection means (13) When the fire melts the wheels (20) and consequently, the assemblage (c) descends, it remains fixed to the guide (a). In this way the assemblage (c) stays attached to the guide (a) and keeps the doors (d) panels in front of the bay (9).
