Elevator system 20 schematically is illustrated among Fig. 1.System 20 be included in the passage 24 motion selectively in case between the differing heights of building 28 or platform 26 elevator cars 22 of carry load.Only schematically illustrate the selection part of car supporting structure in the passage 24, although and only represent a platform 26, those skilled in the art will appreciate that elevator system usually can be near a plurality of height or the platform in the building.

Building 28 comprises roof surface 30.Example illustrated comprises the channel roof 32 of extending slightly on most of roof surface.The present invention is applicable to that also channel roof 32 is not higher than the situation of roof surface 30.

Roof unit 34 is fixed on the channel roof 32.Shown in top unit 34 comprise support plinth 36 and lid 38.Support plinth 36 preferably for good and all is fixed on roof 30 or the channel roof 32.In an example, base 36 comprises one group at least two horizontal location beams that are positioned on the passage.Roof 30 and channel roof 32 are commonly referred to as " roof surface " in this file.

Lid 38 preferably for good and all is not fixed on roof or the support plinth 36.On the contrary, lid 38 at last can be from the support plinth dismounting so that near the parts by support plinth 36 supportings.In an example, need hoisting crane or similar machine to dismantle whole lid.In another example, having only the part of lid is detouchable.

Lid 38 preferably is received so that form closed interface 39 between lid and support plinth 36.The example fixation configuration comprises the fastener that for example lid is fixed to for example bolt on the base.In an example, between interface 39, do not need packing element or material separately.

In another example, roof surface comprises the constraint portions that forms a roof surface part.Constraint portions is not influenced by natural cause as the marginal operation of support plinth 36 so that with the protection machine part mode receives covers 38.

Example shown in Figure 1 comprises the opening 40 by covering 38 1 sides.Example illustrated comprises pivotally attached supporting member 42, and this supporting member makes that cover a part of 38 moves selectively, so that can pass through the inside of opening 40 near unit 34.Although the multiple parts that opening of expression in Fig. 1, a plurality of this openings and being used for cover this opening selectively also within the scope of the invention.

As clearly shown in Figure 2, support plinth 36 preferably supports machine component 44, and power is provided this assembly so that motion elevator cars 22 in passage 24 as required.Machine component 44 is preferably compared very compact with the conventional machines assembly, the conventional machines assembly needs whole equipment room to hold motor and other parts.Example illustrated comprises controls the preferably motor controller 46 of motor 48 operations of electric notor.Driving pulley 50 responds the motion of motors 48 and rotates, so that cause the motion of a plurality of bands (being rope) 52 on the driving pulley 40, makes car 22 move as required.A plurality of tape terminals 54 preferably are bearing in the roof unit 34.

In addition, for example the temperature control apparatus 56 of fan or temperature booster can advantageously be bearing in the roof unit 34.

Support plinth 36 and lid 38 form the housing that holds machine component 44 parts on the roof surface that is bearing in building fully together.Opening (accompanying drawing is not shown) by support plinth 36 makes rope 52 extend downwardly in the passage, so elevator system can be carried out suitable operation.

In an example, the bottom-to-top-height of roof unit 34 on the roof surface of channel roof 32 is less than 1 meter.In an example, the top of lid 38 has only about 77 decimeters (2 feet 7 inches) on the top surface of channel roof 32.Compare with the traditional machine room on being bearing in roof surface, the overall dimensions of assembly 34 significantly reduces.

Multiple material can be used to make lid, support plinth or both.Example comprises corrosion-resistant steel, aluminium, glass-felt plastic and plastics.Selected material must stand the expectation environmental conditions of this building position.The people that have benefited from this specification sheets will appreciate that multiple material will satisfy the special requirement of particular case, and can select to be best suited for the material of this situation.

Illustrate as Fig. 3 is clear, support plinth 36 comprises the susceptor surface 60 that is roughly the plane in the example shown.A plurality of side parts 62 extend upward (with respect to the roof) and leave plane surface 60.The height of side part 62 is preferably selected according to the typical precipitation of building location.If in advance in respect of snowfall, snowfall also must be considered so that guarantee to protect fully machine part.Regional architecture thing coding can be determined the desired height of sidepiece 62.In an example, this highly is 200 millimeters.

Lid 38 comprises that top 64 and a plurality of extension leave a plurality of sidewalls 66 at top.In the example shown, lid 38 sidewall 66 is contained in the space that the sidewall 62 of support plinth 36 limits.Between sidewall 66 and sidewall 62, suitably assemble at the interface and guarantee that natural cause (being rain or snow) does not enter in the spaces of covering 38 protections, make the machine part that supports by support plinth 36 keep isolated as required with environment.

Fig. 3 example comprises the part 70 that is articulated and connected that covers between 38 parts.In this example, can manually lift around the part that is articulated and connected to front side (according to accompanying drawing), so that approaching via opening 40.

Remarkable advantage of the present invention is can save the space by the unique and compact configuration of parts.Another remarkable advantage is to have the lid 38 that the dismounting selected is arranged, make the individual easily near the parts in the roof unit 34 so that install as required, safeguard or change.
