IMPROVEMENTS IN OR RELATING TO LIFT CARS
This invention relates to a lift car for assembly in an enclosed lift shaft, a method of assembling a lift car within an enclosed lift shaft, and an interlocking panel for a wall of a lift car.
A lift (or elevator) is a vertical transportation device that typically moves people or goods between the floors of a building, vessel or other structure. Contemporary lifts comprise a lift car, having a floor and walls which define an interior in which the said people and/or goods are, in use, carried.
According to a first aspect of the invention there is provided a lift car, for assembly in an enclosed lift shaft, comprising a floor having a plurality of wall panels secured thereto, each wall panel having a front face arranged to define an interior of the lift car and each wall panel being so secured by at least one fastener arrangement having an operative portion located within the interior of the lift car.
Having a lift car in which a plurality of its wall panels is each secured to a floor of the lift car by at least one fastener arrangement having an operative portion located within the interior of the lift car means that an assembly operative can access the operative portion of each fastener arrangement to cause securing of the corresponding wall panel to the floor from within the interior of the lift car.
Avoiding the need for such an operative to work outside of the lift car is very desirable because working outside the lift car can be difficult, time-consuming and dangerous when assembly of a lift car takes place within a lift shaft, where typically the clearance between the lift car and lift shaft is only around 150mm.
As a consequence, the lift car of the invention can be assembled considerably more quickly and much more safely than a conventional lift car requiring access by an assembly operative to an exterior thereof.
Preferably the front face of each of the plurality of wall panels lies between first and second sides that extend in a lengthwise direction, the first and second sides having respective first and second interlocking formations depending therefrom, the first interlocking formation of one wall panel and the second interlocking formation of another wall panel being configured to cooperate with one another to initially permit receiving of the second interlocking formation within the first interlocking formation via movement in a direction perpendicular to the lengthwise direction and thereafter to retain the wall panels in abutment with one another.
The provision of first and second interlocking formations that are configured to cooperate with one another to initially permit receiving of the second interlocking formation within the first interlocking formation via movement in a direction perpendicular to the lengthwise direction, avoids the need for undue movement of the first and second wall panels relative to one another in the lengthwise direction which might otherwise be difficult, e.g. within the tight confines of a lift shaft when assembling a wall of a lift car.
In the meantime, having first and second interlocking formations that are also configured to cooperate with one another to thereafter retain the wall panels in abutment with one another inhibits movement of one wall panel away from the other in a widthwise direction, and so reduces the need to otherwise secure one wall panel to another along their respective lengths, which again could be difficult, e.g. within the tight confines of a lift shaft.
Optionally the first interlocking formation includes a first receiving portion configured to receive and retain in a widthwise direction a first portion of the second interlocking formation.
The inclusion of such a first receiving portion and first portion of the second interlocking formation provides a practical way of implementing the desired cooperative functionality of the first and second interlocking formations.
In a preferred embodiment of the invention the first interlocking formation of one wall panel and the second interlocking formation of the other wall panel are further configured to cooperate with one another after initial receiving of the second interlocking formation within the first interlocking formation to retain the wall panels in a coplanar arrangement.
Retaining the wall panels in a coplanar arrangement inhibits movement of one wall panel away from the other in a transverse direction, i.e. in a direction perpendicular to both the lengthwise direction and the widthwise direction, and so reduces still further the need to secure one wall panel to another along their respective lengths while nevertheless presenting a robust and secure arrangement of wall panels to an interior of the lift car.
The first interlocking formation may include a second receiving portion configured to receive and retain in a transverse direction a second portion of the second interlocking formation.
The inclusion of such a second receiving portion and second portion of the second interlocking formation again provides a practical way of implementing the desired further cooperative functionality of the first and second interlocking formations.
In another preferred embodiment of the invention the first interlocking formation of one wall panel and the second interlocking formation of the other wall panel are still further configured to cooperate with one another after initial receiving of the second interlocking formation within the first interlocking formation to allow pivotal movement through an arc of one wall panel relative to the other.
Having the first and second interlocking formations so still further configured facilitates movement of the wall panels into a coplanar arrangement after the after initial receiving of the second interlocking formation within the first interlocking formation.
Optionally the second interlocking formation includes a bevelled portion.
The inclusion of a bevelled portion assists in allowing the said pivotal movement through an arc of the first and second locking formations relative to one another.
Preferably each fastener arrangement includes a mechanical fastener which defines the operative portion.
Mechanical fasteners are readily available and can be easily manipulated by an assembly operative.
In a still further preferred embodiment of the invention each fastener arrangement includes a securing formation fixedly connected to the floor, each securing formation defining an aperture through which a corresponding mechanical fastener passes to secure a corresponding wall panel to the floor.
Including such securing formations assists in the assembly of the lift car without, e.g. the need to additionally modify the respective wall panels, i.e. other than to provide them with the first and second interlocking formations.
Optionally a plurality of individual securing formations is provided within a unitary securing member.
Such an arrangement assists in fixedly connecting rapidly a number of securing formations to the floor, and so helps to further reduce the time taken to assemble the lift car of the invention.
At least one fastener arrangement may include a mechanical fastener retaining formation coupled with a corresponding wall panel to engage with and at least temporarily retain a corresponding mechanical fastener.
The inclusion of one more mechanical fastener retaining formations desirably allows an assembly operative to retain the or each correspond mechanical fastener, and thereby cause securing of the associated wall panel to the floor, by accessing and manipulating the or each said mechanical fastener solely from within the interior of the lift car.
According to a second aspect of the invention there is provided a method of assembling a lift car within an enclosed lift shaft comprising the steps of:
(a) providing a floor;
(b) providing a plurality of wall panels, each having a front face arranged to define an interior of the lift car;
(c) providing at least one fastener arrangement for each wall panel, each fastener arrangement having an operative portion located within the interior of the lift car; and (d) accessing the operative portion of each fastener arrangement from within the interior of the lift car to cause securing of each corresponding wall panel to the floor.
Accessing the operative portion of each fastener arrangement from within the interior of the lift car to cause securing of each corresponding wall panel to the floor avoids the need for an assembly operative to work outside of the lift car, and is very desirable because, as mentioned above, working outside the lift car can be difficult, time-consuming and dangerous when assembly of a lift car takes place within a lift shaft.
As a consequence, the method of the invention allows a lift car to be assembled considerably more quickly and much more safely than conventional methods requiring access by an assembly operative to an exterior of the lift car during assembly.
Preferably step (b) of providing a plurality of wall panels includes:
configuring the front face of each wall panel to lie between first and second sides that extend in a lengthwise direction, providing the first and second sides with respective first and second interlocking formations depending therefrom, the first interlocking formation of one wall panel and the second interlocking formation of another wall panel being configured to cooperate with one another to initially permit receiving of the second interlocking formation within the first interlocking formation and thereafter to retain the wall panels in abutment with one another; and causing the second interlocking formation to be received within the first interlocking formation via movement in a direction perpendicular to the lengthwise direction.
Providing first and second interlocking formations that are configured to cooperate with one another to retain the wall panels in abutment with one another inhibits movement of one wall panel away from the other in a widthwise direction, and so reduces the need to otherwise secure one wall panel to another along their respective lengths, which could be difficult, e.g. within the tight confines of a lift shaft.
Meanwhile, causing the second interlocking formation to be received within the first interlocking formation via movement in a direction perpendicular to the lengthwise direction avoids the undue need for movement of the first and second wall panels relative to one another in the lengthwise direction which again might otherwise be difficult, e.g. within the tight confines of a lift shaft when assembling the lift car.
Step (b) of providing a plurality of wall panels may further include:
providing first and second interlocking formations of respective wall panels which are further configured to cooperate with one another after initial receiving of the second interlocking formation within the first interlocking formation to retain the wall panels in a coplanar arrangement; and causing pivotal movement through an arc of one wall panel relative to the other after initial receiving of the second interlocking formation within the first interlocking formation.
Providing first and second interlocking formations of respective wall panels which are further configured to cooperate with one another after initial receiving of the second interlocking formation within the first interlocking formation to retain the wall panels in a coplanar arrangement inhibits movement of one wall panel away from the other in a transverse direction, i.e. in a direction perpendicular to both the lengthwise direction and the widthwise direction, and so reduces still further the need to secure one wall panel to another along their respective lengths.
In the meantime, causing pivotal movement through an arc of one wall panel relative to the other after initial receiving of the second interlocking formation within the first interlocking formation desirably moves the wall panels into the aforementioned advantageous coplanar arrangement after the after initial receiving of the second interlocking formation within the first interlocking formation.
According to a third aspect of the invention there is provided an interlocking panel, for a wall of a lift car, comprising a front face lying between first and second sides that extend in a lengthwise direction, the first and second sides having respective first and second interlocking formations depending therefrom, the first and second interlocking formations being configured to cooperate with one another to in use initially permit receiving of the second interlocking formation of one interlocking panel within the first interlocking formation of another interlocking panel via movement in a direction perpendicular to the lengthwise direction and thereafter retain the interlocking panels in abutment with one another and in a coplanar arrangement.
Having first and second interlocking formations that are configured to cooperate with one another to in use initially permit receiving of the second interlocking formation of one interlocking panel within the first interlocking formation of another interlocking panel via movement in a direction perpendicular to the lengthwise direction, allows one interlocking panel to engage with another interlocking panel without the need for undue movement of the panels relative to one another in the lengthwise direction which might otherwise be difficult, e.g. within the tight confines of a lift shaft when assembling a wall of a lift car.
Meanwhile, the ability to retain the interlocking panels in abutment with one another and in a coplanar arrangement allows for the provision of an extremely robust and resilient wall structure within, e.g. a lift car, without the need for any secondary securing of the interlocking panels to one another along their lengths, which again could be difficult e.g. within the tight confines of a lift shaft when assembling the wall.
Preferably the first and second interlocking formations are still further configured to cooperate with one another to in use allow pivotal movement through an arc of one interlocking panel relative to the other after initial receiving of the second interlocking formation within the first interlocking formation.
Such functionality assists further in engaging one interlocking panel with another, e.g. within the tight confines of a lift shaft.
There now follows a brief description of preferred embodiments of the invention, by way of non-limiting examples, with reference being made to the following figures in which:
Figure 1(a) shows a perspective view from a first side of a first portion of a lift car according to a first embodiment of the invention;
Figure 1(b) shows a perspective view from a second opposite side of the first portion of the lift car shown in Figure 1(a);
Figure 1(c) shows a perspective view of a second portion of the lift car shown in Figure 1(a);
Figures 2(a) to 2(c) show first and second wall panels which form a part of the lift car shown in Figure 1(a) during various stages of assembly;
Figure 3 shows portions of first and second wall panels which form a part of a lift car according to another embodiment of the invention;
Figure 4 shows a floor and a unitary securing member which form a part of a lift car according to a further embodiment of the invention; and
Figure 5 illustrates one way in which a roof may be secured to a wall of the lift car shown in Figure 1(a).
A lift car according to a first embodiment of the invention is designated generally by reference numeral 10, as shown in Figures 1(a) to 1(c).
The lift car 10 includes a floor 12 which has a plurality of identical wall panels 14 secured thereto. Each wall panel 14 has a front face 16 which is arranged to define an interior 18 of the lift car 10.
More particularly, as shown most clearly in Figures 2(a) to 2(c), the front face 16 of each of the plurality of wall panels 14 lies between first and second sides 20, 22 that extend in a lengthwise direction L. The first side 20 has a first interlocking formation 24 which depends therefrom opposite the front face 16 and the second side 22 has a second interlocking formation 26 that similarly depends therefrom opposite the front face 16.
The first interlocking formation 24 of a first wall panel 14 and the second interlocking formation 26 of a second wall panel 14 are configured to cooperate with one another to initially permit receiving of the second interlocking formation 26 within the first interlocking formation 24 via movement in a direction perpendicular to the lengthwise direction I_d, and more particularly in a transverse direction Td which extends perpendicularly to both the aforesaid lengthwise direction Ld and a widthwise direction Wd of the first wall panel 14, as best shown in Figure 2(a).
The first and second interlocking formations 24, 26 are also configured to cooperate with one another to thereafter retain the wall panels 14 in both abutment with one another and in a coplanar arrangement, as shown most clearly in Figure 2(c). In this manner the wall panels 14 can be considered more generally to be interlocking panels.
In the embodiment shown the first interlocking formation 24 includes a first receiving portion 28 that is configured to receive and retain in the widthwise direction Wd a first portion 30 of the second interlocking formation 26, so as to provide the aforementioned retention of the wall panels 14 in abutment with one another and thereby inhibit movement of the wall panels 14 away from one another in the said widthwise direction Wd.
In addition, in the embodiment shown the first interlocking formation 24 includes a second receiving portion 32 which is configured to receive and retain in the transverse direction To a second portion 34 of the second interlocking formation 34, in order to provide the retention of the wall panels 14 in the coplanar arrangement mentioned above and thereby also inhibit movement of the wall panels 14 away from one another in the said transverse direction Td.
Also in the embodiment shown, the first and second interlocking formations 24, 26 are still further configured to cooperate with one another after initial receiving of the second interlocking formation 26 within the first interlocking formation 24 to allow pivotal movement through an arc Ma of one wall panel 14 relative to the other, as best shown in Figure 2(b). Such movement is facilitated by the inclusion in the second interlocking formation 26 of a bevelled portion 36, which in the embodiment shown takes the form of a chamfer 38, although other profiles may also be used.
In other embodiments of the invention, the configuration of the first and second interlocking formations 24, 26 may differ from that described hereinabove. For example, the first interlocking formation 24 may, as shown in Figure 3, include an elongate spacing member which extends along the length thereof and lies between the first interlocking formation 24 and the second interlocking formation 26 to provide a lift car according to a further embodiment of the invention with an interior having a different appearance.
Returning to the lift car 10 shown in Figures 1(a) to 1(c), each wall panel 14 is secured to the floor 12 by a fastener arrangement 42.
Each fastener arrangement 42 includes a mechanical fastener 44 which, in the embodiment shown, takes the form of a threaded bolt 46 that has a head 48 which defines an operative portion 50 of each fastener arrangement 42, i.e. defines the portion of each fastener arrangement 42 that an assembly operative accesses and manipulates during assembly of the lift car 10 to cause securing of the corresponding wall panel 14 to the floor
12. Other types of mechanical fastener may, however, also be used, such as screws, clips, pins, rivets, anchors and the like. In each such other instance nevertheless, the mechanical faster defines the operative portion that is accessed to cause securing of the corresponding wall panel to the floor.
In addition to the foregoing, each fastener arrangement 42 includes a securing formation 52 that is fixedly connected to the floor 12, and which defines an aperture 54 through which the corresponding mechanical fastener 44, i.e. corresponding bolt 46, passes to secure a corresponding wall panel 14 to the floor 12.
More particularly, in the embodiment shown, a number of individual securing formations 52 is provided within a unitary securing member 56 which takes the form of an angle iron 58 with a plurality of elongate slots 60 formed in an upstanding leg 62 thereof. As desired, a given elongate slot 60 defines the aperture 54 through which a corresponding bolt 46 passes. Meanwhile the other leg 64 of the angle iron 58 is directly welded to the floor 12, although it may also be fixedly connected to the floor 12 in a different manner. For example, as shown in Figure 4, the other leg 64 of the angle iron 58 may be extended to form a Ushaped unitary securing member 66 which is, in turn, fixedly secured to a floor 12 by a brace member 68 that, optionally may be used to secure, e.g. bolt, a plurality of floor sections 12A, 12B to one another.
As well as the above, each fastener arrangement 42 includes a mechanical fastener retaining formation 70 that is coupled with the corresponding wall panel 14 to engage with and temporarily retain the corresponding mechanical fastener 44, i.e. the corresponding bolt 46. Each mechanical fastener retaining formation 70 takes the form of a captive thread formation 72, and more particularly a threaded boss 74 that is crimped to the corresponding wall panel 14, although other retaining formations may be used.
As shown in Figures 1(a) to 1(c), the fastener arrangements 42 are positioned so that the operative portion 50 of each, i.e. the head 48 of each bolt 46, is located within the interior 18 of the lift car 10.
In addition to the wall panels 14 described herein above, the first lift car 10 also includes four corner wall panels 114 (only one of which is shown, in Figure 1 (c)) that have front face portions 116 which lie perpendicular to one another to define an internal corner 118 of the lift car 10. The corner wall panels 114 otherwise include first and second sides that have first and second interlocking formations 24, 26 depending therefrom which are identical to those of the wall panels 14 already described. The corner wall panels 114 are also secured to the floor 12 in the same manner as the other wall panels 14, i.e. by identical fastener arrangements 42.
Although not shown in Figures 1(a) to 1(c), the first lift car 10 has a roof 76 with an engagement formation 78 that sits on a distal end 80 of each wall panel 14, 114 spaced from the floor 12, in the manner shown in Figure 5.
The lift car 10 is assembled within an enclosed lift shaft (not shown) principally by:
(a) providing the floor 12;
(b) providing a plurality of the wall panels 14, 114 described hereinabove;
(c) providing a plurality of fastener arrangements 42 in the form described hereinabove; and (d) accessing the operative portion 50 of each fastener arrangement 42, i.e. the head 48 of each bolt 46, solely from within the interior 18 of the lift car 10 to cause securing of each corresponding wall panel 14, 114 to the floor 12, i.e. by engaging with the head 48 of each bolt 46 to manipulate and drive each bolt 46 through a corresponding aperture 54 defined by a coincident elongate slot 60 in the corresponding unitary securing member 56 and on into the corresponding threaded boss 74 crimped to the said corresponding wall panel 14, 114.
In addition, such assembly includes, as part of providing a plurality of wall panels 14, 114:
causing the second interlocking formation 26 of one wall panel 14, 114 to be received within the first interlocking formation 24 of another wall panel 14,114 via relative movement of the wall panels 14, 114 in a direction perpendicular to the lengthwise direction LD, i.e. via movement in a transverse direction TD relative to the other wall panel 14, as shown in Figure 2(a); and thereafter causing pivotal movement through an arc Ma of one wall panel 14, 114 relative to the other wall panel 14, 114, as shown in Figure 2(b), in order to have the wall panels 14,
114 retained in both abutment with one another and in a coplanar arrangement, as shown in Figure 2(c).
Such movement of respective wall panels 14, 114 relative to one another typically is carried out with one of the panels 14, 114 already secured to the floor 12, although this need not necessarily always be the case.
