Definitions

  • the present invention is intended for a integral system of corner brackets for an elevator frame, which allows an elevator frame to be manufactured from said corner brackets wherein all the dynamic elements needed in an elevator frame such as safety and guidance systems are integrated.
  • the system object of the invention is formed by two lower corner brackets forming part of the elevator frame and which include such safety and guidance systems.
  • the two upper corner brackets or only one of them, can also be used.
  • the system integrates the lower resistant part of the frame with safety and guidance equipments, which allows an elevator frame to be manufactured from the corner brackets and just adding vertical stringers and horizontal transoms, which simplifies the manufacturing process since the stringers do not have to be adapted to the parachute conditions.
  • Elevator frames are known in the state of the art. Said frames support the weight of the cabin and people who are inside.
  • the frames are basically composed of a resistant structure with rectangular shape inside of which the cabin is placed.
  • the cabin directly or indirectly rests on the bottom of the frame, formed by two or more pieces called lower transoms.
  • Said transoms are directly connected at their ends to vertical pieces called stringers, which shift the load to an upper piece or pieces of the frame called upper transoms.
  • the upper ends of stringers are directly connected to the ends of the upper transom.
  • the configuration is called “gantry” and if the cabin is off-centered the configuration is called “backpack”.
  • the basic structure consists of stringers and transoms directly connected to each other.
  • the speed limiter is also placed on said frame. This can be done in two ways: directly on the frame or as a subsystem formed by parachutes and limiter, but in any case, this subsystem has no resistant purpose over the frame. Sometimes the parachute alone or the parachute together with the limiter is placed on a support installed at the bottom of the frame.
  • the present invention relates to a corner bracket integrated system for elevator frame, which allows an elevator frame to be manufactured from said corner brackets wherein all the dynamic elements needed in an elevator frame such as safety and guidance systems are integrated.
  • the integral system of corner brackets of the present invention besides incorporating safety and guidance elements, has a structural function within the frame, so that the loads generated by the cabin are shifted to the stringers through the integral system of corner brackets of the present invention, and not directly.
  • the integral system of corner brackets includes two lower corner brackets that comprise safety and guidance systems, and two upper corner brackets incorporating the guidance system.
  • Guidance systems are responsible for maintaining the frame in contact with the installation guides; slide or roller guide shoes may be used.
  • Security systems are a pair of parachutes that allow the frame to be wedged into the guides in case of emergency, and a speed limiter which wedges the parachutes if a predetermined speed limit is exceeded.
  • the lower corner brackets consist of a main base plate wherein the parachute and guidance system are integrated, which can be a slide or roller guide shoe. Of the two lower corner brackets, one left and one right, one further includes the speed limiter.
  • each lower corner bracket On the top of each lower corner bracket two vertical stringers are connected through connecting means.
  • the central part of each corner bracket has some folds and holes suitable for fitting the horizontal transoms therein. Once fitted into the holes, said transoms can be connected through connecting means, each lower corner bracket also having a series of holes for fixing the parachute.
  • Each lower corner bracket has a friction plate that can be placed at its bottom, below the parachute or either at the top of the corner bracket, above the parachute.
  • Roller guide shoes can also be placed over or beneath the parachute.
  • Each upper corner bracket consists of a main base plate that comprises the guidance system, which can be a slide or roller guide shoe. There is an upper left corner bracket and an upper right corner bracket.
  • the upper corner bracket on the same side wherein the speed limiter is located further comprises the return pulley for the speed limiter cable.
  • corner brackets support the parachutes driving mechanism, allowing both to be connected in order to act simultaneously.
  • the integral system of corner brackets allows assembling the frame with the width, height and payload data thus determining the extent of stringers and transoms.
  • the payload determines the parachute model to be placed in the corner bracket. Depending on the payload and the extensions, the length and section measurements of the transoms and stringers are determined.
  • the central part of the corner bracket houses the parachute, while the top allows placing a stringer narrower than it would be necessary in order to house the parachute therein.
  • the integral system of corner brackets has enough robustness to withstand loads generated during the emergency braking and shift them to the guides, which allows placing a stringer of lower section than those placed in the frames of state of the art, wherein the parachute is placed on the stringer.
  • the integral system of corner brackets acts as base plate for the driving mechanism and as a main support for the limiter, cable of which is held to the guides and may be tightening by mass, springs or a mixed system, whereas the use of the limiter with return pulley in an upper corner bracket makes the rack also suitable for installations with reduced pit.
  • the integral system of corner brackets can have a configuration without speed limiter, in which case the lower corner bracket consists of a base plate wherein the parachute and the guidance system, which can be slide or roller guide shoe are integrated, there being a lower left corner bracket a lower right corner bracket.
  • the upper corner brackets are similar, consisting of a main base plate comprising the guidance system, which can be slide or roller guide shoe, there being also a left corner bracket and a right corner bracket.
  • the present invention can also be made with multiple combinations of components, all of which being object of the present invention, that is to say:
  • Another object of the present invention is the use of the main plate of each corner bracket as fastening system for slip elements of the slide shoes, thus avoiding the need to use the slip material support of known slide shoes.
  • the present invention relates to a set of two upper corner brackets and two lower corner brackets in order to simplify the manufacturing and assembly of a frame sliding through the guides (22) of the elevator shaft.
  • the lower corner bracket (1) consists of the following components: a main plate (2), on which a friction plate (3) or guidance system is placed, a parachute (4), the driving mechanism (5) and a speed limiter (6).
  • the top of the main plate (2) of the lower corner bracket (1) is connected by screws (7) to a stringer (8), whereas the central part of the main plate (2) of the lower corner bracket (1) is connected by screws (9) to two horizontal transoms (10).
  • FIG 2 shows the detail of an upper corner bracket (17) with return pulley (12).
  • the cable of speed limiter (11) passes through the return pulley (12) for allowing the proper actuation of the speed limiter (6).
  • the return pulley (12) is held by an axis (13) to the main plate (14) of the upper corner bracket and to an auxiliary plate (15), whereas the main base plate (14) supports an upper friction plate (16).
  • the upper corner (17) comprises the following components: main plate (14), auxiliary plate (15), axis (13), return pulley (12) and friction plate (16).
  • the entire frame, shown in Figure 3 including the integrated system has a lower corner bracket (1) with friction plate (3), parachute (4) and limiter (6), a stringer (8), an upper corner bracket (17) with a return pulley (12) and friction plate (16), upper transom (18), an upper corner bracket (19) with slide show, a stringer (20), a lower corner bracket (21) with slide shoes and parachutes, and finally transoms (10).
  • the speed limiter (6) is included in the lower corner bracket (1) and moves therewith, so that in order to detect speeding and actuate the parachute (4) it is provided with a static cable (11) placed along the entire path. This is done via a cable tied to the top of the shaft and to the bottom of the shaft.
  • a return pulley (12) is placed at the top of the frame, specifically in the upper corner bracket with return pulley (17) for ensuring proper contact between the speed limiter (6) and the cable (11) of the limiter.
  • Figures 1 , 2 , 10 show how the cable of the speed limiter (11) which is held to the top of the shaft goes down to the speed limiter (6), maintains a contact of 180° and goes up towards the return pulley (12), therewith maintaining a contact of 180° and continues down to the lower tying of the limiter cable placed in the pit.
  • the integral system described above can be used for manufacturing a gantry-type and also a backpack-type frame.
