Description

TECHNICAL FIELD The present invention relates to a freight elevator and a building equipped with such a freight elevator, for example a dwelling house equipped with a freight elevator for mounting wood from a lower floor to an upper floor.

PRIOR ART Many buildings, such as dwelling houses, are equipped with an open fireplace or a fireplace with insert. These fireplaces are used occasionally to create a warm atmosphere or a regular way to heat the room, or even the entire house. For heating, the chimney can be used in addition to another type of heating or main way. Whatever its use, the chimney requires the frequent supply of logs of wood. This supply operation involves handling the logs to put them in the home. In addition, for reasons of space, aesthetics, hygiene and safety, the stock of wood is often far from the chimney. In many cases, the main stock of wood is located on the lower floor in relation to the chimney, for example in a garage or cellar. To be able to feed the chimney at any time, it is therefore advisable, as and when consuming wood, to move the logs from the main stock to an intermediate stock, preferably located in the environment close to the fireplace. Because of the weight of logs and their size, this movement of logs is particularly painful to achieve, especially when it must be made between two floors.

VOILX1-EN-1 _TEXTE REMOVAL CL / SL - 2 - Indeed, this movement requires many round trips, even when several logs are transported at a time. In addition, the risk of falling logs and / or the person wearing them is important, especially for people of a certain age. Some lifts are in the form of an elevator provided with a cage connecting the lower and upper floors and in which a tray is moved. For this purpose, the cage may comprise side racks meshing with a toothed wheel carried by the tray. This gear wheel is rotated by an electric motor causing its rotation and movement of the tray along the slides. This type of hoists preferably includes a brake to slow down, or even stop the descent of the tank in case of failure of the electric motor. These lifts therefore require automated means whose maintenance requires the intervention of a professional. In addition, these lifts involve the permanent installation of a cumbersome cage and often unsightly. Finally, these lifts are expensive. For these reasons, these hoists are poorly suited to residential houses and budgets of individuals. Other hoists are in the form of openings made in the wall separating the lower and upper floors, for example a slab. Each opening allows the passage of a tank, for example connected to the ceiling of the upper floor by a chain coupled to a motorized winch and for pulling the ferry to the upper floor and accompanying its descent to the lower floor . The previous freight lifts can of course be manual, which reduces their costs to the detriment of the physical strength they require then to be maneuvered. The present invention aims to remedy these drawbacks by proposing a freight elevator and a building equipped with such an elevator, the elevator being simple to use, little expensive, limited space in particular at the level of the lower floor of the building in which it is installed and to facilitate the movement of load between two floors while limiting the risk of contamination related to the displacement of load, this displacement can be made safe for both people and the displaced load.

The invention relates to a freight elevator comprising at least one movable element provided with at least one loading location adapted to receive and support a load, moving means adapted to move said movable element between a low position and a high position in wherein said movable member can be loaded and unloaded, said elevator also having means for guiding said movable member as it moves between said low and high positions. This hoist is remarkable in that said guide means comprise telescopic arms each formed of two portions movable in longitudinal translation relative to each other to follow the movement of said movable member between its high and low positions, the one of said portions being intended to be coupled to a fixed support, another of said portions being coupled to said movable element, said first and second portions being arranged to be slid and fitted into each other so as to reduce the length of said telescopic arm in said upper position of said movable member. VOILX1-EN-1 _TEXTE REMOVAL CUSL 2958635 - 4 - The telescopic arms and their fixing method thus make it possible to limit the size of the freight elevator when it is in its high position. In addition, load handling is limited, the elevator 5 according to the invention allows, especially when used to move logs, to limit soiling generated by the load movement. The movable member preferably has a general parallelogram shape, said telescopic arms are four in number and each has an end secured to one of the corners of said parallelogram. Said movable element advantageously comprises a base extended by walls forming a tray, said walls of said tray being provided with clearances each preserving an outer housing adapted to receive one of said portions whose lower end is secured to said base and allowing the moving at least one other of said portions between said second portion and said wall during movement of said movable member 20 between its up and down positions so that said telescopic arms do not protrude laterally from said base and a functional play is preserved between the portions and said walls to allow their respective relative sliding. When the movable element has a parallelogram shape, said clearances are advantageously provided in the corners of this parallelogram. Preferably, said portions are coupled together, in pairs, by locking means 30 limiting the longitudinal displacement of said portions at least in the lower position of said movable member. According to a preferred embodiment, said locking means comprise at least one lateral stud provided on one of said portions and at least one inner longitudinal groove provided with an abutment provided on a other of said portions, said groove being adapted to receive said pin and allow its longitudinal displacement when said movable member is moved between its high and low positions, said stop being adapted to cooperate with said pin to block said longitudinal movement in said lower position. Thus, the elevator does not require additional means or support to delimit its low position and keep it in this low position. Advantageously, said movable element comprises at least one insulating layer extending under said loading location and capable of isolating said loading location from below said movable element. Said displacement means may comprise at least one link, one end of which is fixed to an attachment point and the other end of which is capable of being coupled to traction means able to vary, in a controlled manner, the length of said link. for moving said movable member between its low and high positions. The point of attachment may be provided on a fixed support of the building in which the elevator is installed or on the ferry itself.

Said traction means advantageously comprise an electric motor.

The invention also relates to a multi-storey building equipped with a freight elevator, said building comprising at least one lower floor and one upper floor separated by at least one floor having at least one opening allowing at least the passage of the movable element a freight elevator having a loading location adapted to receive and support a load, said elevator being VOILX1-FR-1 TEXTE REMOVAL CUSL 2958635 - 6 - movable between a low position in which at least a part of the loading location is accessible from said lower stage and a high position in which at least a portion of the loading location is accessible from said upper stage, said elevator also having means for guiding said movable member as it moves between said low and high positions. This building is remarkable in that it comprises at least one elevator as described above and in that said guide means of said elevator are arranged to connect said building to said movable element of said elevator. Advantageously, said upper stage comprises a box provided above said opening, said box and said opening being able to receive at least partly said portions of said telescopic arms forming said guide means and at least a portion of said movable member when he is in his high position.

BEST MODE FOR CARRYING OUT THE INVENTION The freight elevator 1 according to the invention is intended to equip any type of building and in particular a dwelling house. In the following, the described building is, without limitation, a dwelling house. With reference to the figures, the freight elevator 1 according to the invention comprises a movable element 2 movable between a low position (FIG. 1B) and a high position (FIG. 1A), displacement means 3 of the movable element 2 and guide means 4 of the movable member 2 during its movement. The building equipped with this hoister 1 comprises a lower stage 10 and an upper stage 11 separated by a floor 12 provided with an opening 13 for the passage of the mobile element 2 of the freight elevator 1. In other modes 20 embodiment not shown, the building has a higher number of floors. The stages can also be separated by single or double slabs or any other means of separating the equivalent stages, the entire thickness of these slabs then being traversed by the opening. According to another embodiment not shown, the building can be equipped with several hoists. In this case, the different hoists can use the same opening or separate openings. The building comprises, on its upper floor 11, a fireplace 14 with open or closed hearth and a box 5. The box 5 is provided above the opening 13 and preferably next to the chimney 14. The box 5 is for example formed by two side walls 50, a rear wall 51 and a top wall 52 and defines an access area at the front. This access zone may be provided with a movable flap (not shown) able to prevent access to the interior of the box. This movable flap can be provided with a mechanical key lock or any other suitable means. As described below, the casing 5 is dimensioned so as to be able to receive the mobile element 2 of the freight elevator 1 and its load when the movable element 2 is in its high position. The casing 5 thus makes it possible to camouflage the freight elevator 1 and in particular the mobile element and its load when the movable element 2 is in its high position. In an alternative embodiment not shown, the building does not have a box. The building will be originally designed to receive the elevator 1 with an opening 13 provided in its floor 12. The opening 13 may also be provided a posteriori in the building. The movable member 2 has a location adapted to receive and support a load, for example logs of wood. In the example, the movable element is in the form of a tray 2 having a base 20 in the form of parallelogram and extended vertically by walls 21, 22, 23, including two side walls 21 and a rear wall 22 of same height. The tray 2 also has a front wall 23 of lower height to the side walls 21 and dorsal 22 to define a hatch to facilitate access to the logs in the tray 2. The tray 2 is for example made of sheet metal of a thickness 2 mm for the side walls 21, dorsal 22 and front 23 and 2.5 mm for the base 20. In other embodiments, the base has a circular shape, elliptical, or any other suitable form. In an alternative embodiment not shown, the base of the tray extends laterally beyond the vertical walls so as to form a bearing surface for VOILXI-FR-1 TEXTE REMOVAL CUSL - 9 - to be pressed under the slab around of the opening. This bearing surface is advantageously provided with a foam seal participating in sealing between the stages. In an alternative embodiment not shown, the front wall of the tray is coupled to a movable flap that can be folded to close the door. This movable flap is for example fixed to the front wall by hinges. It can be made of 2 mm thick sheet metal and be provided with a mechanical key lock or any other suitable means.

When the tray 2 is in its high position, the hatch is opposite the access zone. In its lower part, the tray 2 comprises an insulating layer 24, extending under the base 20 and visible in Figure 2C. This insulating layer 24 is for example formed by a compartment filled with thermal insulating material and / or sound, such as for example rock wool. As detailed below, this insulating layer 24 is intended to prevent heat loss between the upper floors 11 and lower 10 of the building when the tray 2 is in its upper position. Each corner of the tray 2 is provided with a clearance 25 providing an outer housing in which may be housed a portion of the guide means 4. The tray 2 is also provided with return bars 26 for cooperating with the moving means. In the example shown, the deflection bars 26 are inclined relative to the base 20 and oriented symmetrically to each other relative to the vertical median plane of the elevator. They can of course have any other configuration.

The guide means comprise four telescopic arms 4 each provided at one of the four corners of the tray 2 and adapted to guide the tray 2 during its movement between its low and high positions. Each telescopic arm 4 comprises portions 40, 41, 42, 43, VOILX1-FR-1 REMOVED TEXT CL / SL - 10 - movable in longitudinal translation relative to each other. In the illustrated example, each telescopic arm 4 comprises four portions 40, 41, 42, 43 including a first and a second portion 40, 41 separated by third and fourth portions 43, 42. Each first portion 40 is secured to the building, for example to the walls of the opening 13 and / or the box 5 by screwing or by any other suitable means, removable or not. Each second portion 41 is disposed outside one of the clearances 25 of the tray 2 so as to preserve a clearance between the clearance 25 and the second portion 41 adapted to receive the passage of the first, third and fourth portions 40, 43, 42. The lower end of each second portion 41 is secured, for example by welding, to the base 20 of the tray 2. The second portions 41 may also be fixed to the base 20 by screws or by any other suitable means, removable or not. The portions 40, 41, 42, 43 have a substantially square section, for example respectively 30 mm, 15 mm, 20 mm and 25 mm side. In this case, the clearance 25 will have a square section preserving a housing for example 35 mm side. The dimensions of the portions 40, 41, 42, 43 and the clearance 25 to preserve a functional game allowing their relative movements. According to an embodiment not shown, the portions 40, 41, 42, 43 have a substantially square cross section, for example 35 mm, 20 mm, 25 mm, 30 mm, respectively, and the clearance 25 has a square section preserving a shape. housing for example 40 mm side. In other embodiments not shown, the portions may also have any other type of section, for example circular. The shape of the clearances provided at the corners of the tray will be adapted to the section of the portions. It is thus possible to provide clearances in a portion of a circle for cylindrical sections. The guiding means may finally comprise a greater or smaller number of portions. In an alternative embodiment not shown, each clearance can be closed by a sheet forming an angle so as to form a closed housing adapted to receive the portions of the corresponding telescopic arm. The dimensions of the portions 40, 41, 42, 43 are provided so that they can be fitted into each other and slide between them. Thus, the first portion 40 is of larger dimensions than the fourth portion 42 itself of greater dimensions than the third portion 43 itself larger than the first portion 40. The portions 40, 41, 42, 43 are moreover coupled together by blocking means. As illustrated by Figures 3A and 3B, the second, third and fourth portions 41, 43, 42 are provided with two lateral pins 44 extending laterally from their lower ends. For reasons of simplification, these pins and grooves are not shown in FIG. 2D. In this embodiment, the pins 44 are in the form of cylindrical fingers. They can of course have any other compatible form. One can also provide a number of pins 44 lower or higher depending on the weight of the tray 2 and the load to move. Moreover, the first, third and fourth portions 40, 43, 42 are provided with internal longitudinal grooves 45 terminated at the bottom by a stop 46. When the portions 40, 41, 42, 43 are arranged one inside the other, the pins 44 are able to circulate longitudinally in the grooves 45 to be in contact with the stop 46. Thus, the pins 44 of the second, third and fourth portions 41, 43, 42 cooperate respectively with the VOILX1-FR-1 _TEXT REMOVAL CUSL 2958635 - 12 - grooves of the third, fourth and first portions 43, 42, 40 to allow the movement of the tray 2 between its high and low positions, the lower position being delimited by the pins 44 bearing against the 5 stops 46, which prevents the relative displacement between the portions 40, 41, 42, 43. Advantageously, the number of the portions 40, 41, 42, 43 and the dimensional characteristics s grooves 45, stops 46 and pins 44 are chosen so that, when the telescopic arm 4 is deployed to the maximum, the tray 2 is not supported on the floor of the lower floor 10. Thus, when the tray 2 is in its low position, it does not require support to receive it. As a result, the lower stage 10 is not encumbered by fixed or moving elements dedicated to the freight elevator 1, elements which would be troublesome in the lower stage 10 when the trough 2 is in its high position and would in particular limit the In this example, the grooves 45 are provided laterally opening. They can of course be provided as non-emergent. According to another embodiment not shown, the position of the nipples and grooves is reversed so that the nipples are provided on the first, third and fourth portions, and that the grooves are provided on the second, third and fourth portions. The displacement means 3 are able to move the tray 2 between its low position (see Figure 1B) in which it can be loaded and its upper position (see Figure 1A) in which it can be discharged. The displacement means 3 are also able to move the tray 2 from its high position to its lower position for a new load. After having mounted the logs of the lower stage 10 to the upper stage 11, the freight elevator 1 can be maintained in its high position, the logs being withdrawn as and when the bin 2 to feed the chimney 14. The freight elevator 1 can also be used in descent-load, namely loaded in the high position (see Figure 1A) and discharged in the low position (see Figure B). The displacement means 3 comprise an electric motor 30 or any equivalent motorization means. This electric motor 30, shown diagrammatically in FIGS. 1A and 1B by a rectangle, is for example a 380-volt electric motor coupled to a gearbox, for example about 46 rpm at the shaft output. The electric motor 30 and its gearbox are arranged under the floor 12. The electric motor 30 is electrically connected to a power supply (not shown) via a switch, for example a double switch, for reversing the direction of rotation of the electric motor 30. The electric motor 30 is coupled to a drive shaft 31 carrying two spaced winch wheels 32, each formed by two disks separated by a winding groove (not shown). The winch wheels 32 are partly received in a housing 15 oriented lower 10 and provided in the thickness of this positioning of the winch wheels 32 do not unnecessarily clutter the floor

the tray has a shutter closing the hatch, the electric motor can be slaved to this hatch and in particular the lock by

The means of displacement 3 links 33 arranged parallel end of each is coupled - 14 - provided under the floor 12 and whose other end is coupled to the winch wheel 32. Between its ends, each link 33 is guided by the bars of Referral 26 provided under the tray 2 and whose ends are for example provided with pulleys (not shown) facilitating the scroll link 33. The return bars 26 may each be coupled to a sheet metal flap closing the top of the passage of the links 33 to prevent them from unintentionally released pulleys, for example when the links 33 are relaxed. The links 33 are each formed for example of a belt, a traction cable or any other equivalent means. According to another embodiment not shown, the attachment points are provided on the tray. Similarly, the moving means may comprise a single winch wheel and a single link. According to yet another embodiment not shown, the drive shaft is coupled to a gear meshing with a chain forming the link.

In an alternative embodiment not shown, the displacement means may comprise two pairs of winch wheels disposed on either side of the tray, each wheel receiving the winding of a link whose end is secured to the tray. The bottom thus has four attachment points capable of receiving each the attachment of one of the links. The winch wheels are connected together by a tensioner to ensure the simultaneous start of their rotation in the opposite direction. In the example shown, in order to pass the tank 2 from its low position (FIG 1B) to its upper position (FIG 1A), the electric motor 30 is energized so as to cause the rotation of the winch wheel 32 in a first direction of rotation. The link 33 wraps in the winding groove until it is energized and its free length decreases. The tray 2 is then progressively raised and moved to the upper stage 11 by the tension of the link 33 applied to the return bars 26 which prevent the friction of the links 33 on the tray 2. The operation of the electric motor 30 is extended until tray 2 reaches its high position. During the movement of the tray 2 from its low position to its high position, it is guided by the telescopic arms 4. The electric motor 30 is for example coupled to an on-off switch (not shown). According to an alternative embodiment not shown, the electric motor can also be coupled to two push button contactors, a contactor controlling the rise of the tray, the other contactor controlling the descent of the tray. These 15 contactors or the on-off switch can be received in a locked box in order to authorize the control of the elevator only to authorized persons. The displacement means 3 may also comprise servo-control means (not shown) cutting off the power supply of the electric motor 30 when the tank 2 is in its high position. The displacement means 3 are also coupled to braking means (not shown) avoiding the involuntary descent of the tray 2 when in its upper position. In the upper position of the tray 2, each telescopic arm 4 has its minimum dimension, all the portions 40, 41, 42, 43 are embedded, that is to say that they are nested one inside the other and slid into place. relative to each other in the first portion 40. The insulating layer 24 of the tray 2 is then located in the thickness of the opening 13 of the floor 12 and maintains a good thermal and / or sound insulation between the upper floors 11 and lower 10. To improve the insulation at the opening 13 of the VOILX1-FR-1 TEXTE REMOVAL CUSL - 16 - floor 12, this opening 13, the box 5 and / or the tray 12 may be provided with a caulking zone (not shown) surrounding the tank 2 and / or the interior of the caisson 5 and / or the opening 13 so as to limit the air passages around the tank 2. These caulking zones comprise, for example flexible elements able to deform. In addition, in this high position, the door is opposite the access area and the logs can be easily entered to feed the chimney 14. Finally, in this high position, the tray 2 is camouflaged in the box 5 and the The lower stage 10 is free of any bulky element connected to the freight elevator 1. To move the tank 2 from its upper position (FIG 1A) to its lower position (FIG 1B), the electric motor 30 is powered and drives the rotation of the winch wheel 32 in a second direction of rotation, opposite to the first direction of rotation, so as to brake and accompany the descent of the tank 2 by allowing the extension, in a controlled manner, of the free length of the 33. Each link 33 progressively unfolds from the winding groove until the tray 2 reaches its low position. During the movement of the tray 2 from its high position to its low position, it is guided by the telescopic arms 4 and the return bars 26 prevent the friction of the links 33 on the tray 2. In the lower position of the tray 2, each telescopic arm 4 has its maximum dimension, all the pins 44 are stopped by the stops 46 and the portions 40, 41, 42, 43 overlap only by their ends. In this low position, the entire loading location of the tray 2 is accessible, facilitating the loading of the tray 2. VOILX1-FR-1 TEXT REMOVAL CUSL - 17 - Possibilities of industrial application The elevator 1 according to the invention can be used in any type of building to move vertically loads for example from one floor to another. The freight elevator 1 is particularly suitable for mounting wood between the basement and the ground floor of a dwelling house equipped with a fireplace or wood stove. The use of the freight elevator 1 is of course not limited to the vertical movement of logs and extends to any type of vertical movement of various loads and buildings with or without a fireplace or stove. It is clear from the foregoing description that the freight elevator 1 according to the invention is simple to make and use, that it is of limited size and reliably, efficiently and safely, to move loads between two floors by limiting the dirt associated with this movement. The lower floor of a building equipped with such a freight elevator 1 is also not encumbered by rigid elements of the elevator.

It is understood that the example described is only a particular illustration and in no way limiting the fields of application of the invention. Those skilled in the art may provide arrangements of size, shape and material to the particular embodiment without departing from the scope of the present invention. VOILX1-FR-1 TEXT REMOVES CUSL
