ELEVATOR GUIDE RAIL SUPPORT MEANS AND ELEVATOR

FIELD OF THE INVENTION

The invention relates to an elevator guide rail support means according to the preamble of claim 1.

5 The invention also relates to an elevator according to the preamble of claim 5.

The expression elevator guide rail support means refers to a support means being used in connection with a guide rail used in an elevator application. An elevator cage moving in a first direction upwards and downwards 10 in a hoistway could be supported on one or several guide rails in the hoistway. The function of the guide rail is to keep the elevator cage in position in the horizontal plane when the elevator cage moves upwards and downwards in the hoistway. The elevator cage can be supported with roller means or glide means on the guide rail. Also a counter weight for the elevator cage could be 15 supported on one or several guide rails in order to keep the counter weight in position in the horizontal plane when the counter weight moves upwards and downwards in the hoistway. These guide rails are supported on the wall structures of the hoistway with suitable support means.

BACKGROUND ART

20 The support means supporting the guide rails of the elevator cage or the counter weight are normally made of some kind of brackets made for a specific elevator type. The brackets are normally made of one piece. A particular bracket can only be used for a specific elevator type. This means that different brackets have to be used for each elevator type. A rather great number £! 25 of different brackets has thus to be kept in storage in order to be able to do w installation work on different elevator types. One has to ensure that the correct ™ brackets are available on the working site. The brackets might be taken to the £: working site by the mechanics doing the installation work on the elevators, x which means that the mechanics must remember to take the correct brackets cc 30 with them when leaving for the working site. There could be different elevator

CO

types on the same working site, which means that the mechanics must have ™ suitable brackets for all of these elevator types when leaving for the working ^ site. The mechanics might also visit several working sites during the working day and need to have brackets for all the elevator types in the different working 2 sites. The rather big number of different brackets results in additional costs in the production and installation process.

There is thus a need for a support means that could somehow resolve the problem relating to the fact that different support means are needed 5 for each elevator type.

BRIEF DESCRIPTION OF THE INVENTION

An object of the present invention is to resolve the problem associated with prior art elevator guide support means and to provide an improved elevator guide support means.

10 The elevator support means according to the invention is character ized by what is stated in the characterizing portion of claim 1.

The elevator according to the invention is characterized by what is stated in the characterizing portion of claim 5.

The elevator support means is characterized in that the support 15 means comprises at least one essentially L-shaped support unit, said at least one support unit comprising at least two separate essentially L-shaped support sheets being stacked together, each branch in each support sheet comprising at least one opening.

The size and/or the strength of the fastening means can easily be 20 altered by changing the number of support units used in the fastening means and/or by changing the number of support sheets used in each support unit. A suitable fastening means for each elevator type can thus be assembled on the working site from identical essentially L shaped support sheets making up a support unit of the fastening means.

25 There is thus no need for the technicians to keep different support £ means with them. The technician can assemble a fastening means on the ™ working site that is suitable for any elevator type from the essentially L shaped

C\J

V support sheets.

^ The openings in each branch in each support sheet are advanta- | 30 geously oblong in the longitudinal direction of the branch. This makes it possi- ^ ble to stack the identical support sheets and still maintain a through opening cö through all the support sheets. There will be a slight deviation in the position of ^ the openings in the identical support sheets when they are stacked due to the o cm thickness of the support sheets.

35 A support means according to a further embodiment of the invention 3 may comprise two support units, said two support units being attached to each other with fastening means so that the combined support means has the form of a lying letter U. The guide rail can be fastened to a first branch of the letter U and the support means can be fastened from the second branch of the letter U 5 to a wall structure of the hoistway. This support means can be used in a situation where the guide rail is to be supported at a wall structure being situated behind the guide rail in the hoistway.

A support means according to a further embodiment of the invention may comprise four support units, a first pair of said four support units being 10 attached to each other with fastening means forming a first lying letter U and a second pair of said four support units being attached to each other with fastening means forming of a second lying letter U, said two lying letters U being attached together with fastening means, the combined support means having the form of two consecutive lying letters U opening in the same direction. The 15 guide rail can be fastened to a lower branch of the lower lying letter U and the support means can be fastened from an upper branch of the upper lying letter U to a wall structure of the hoistway. This support means can be used in a situation where the guide rail is to be supported at a wall structure being situated behind the guide rail in the hoistway. The guide rail will be at a greater 20 distance from the wall structure in the hoistway when this support means is used.

5 DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Fig. 1 shows a vertical cross section of an elevator in a hoistway. The elevator comprises the following main parts: an elevator cage 10, a hoitsway 20, a machine room 30, lifting machinery 40, ropes 41, guide rails 50, 60 and a counter weight 42. The lifting machinery 40 moves the elevator cage 10 10 in a first direction S1 upwards and downwards in the vertically extending hoistway 20. The elevator cage 10 is carried by the ropes 41, which connect the elevator cage 10 to the counter weight 42. The elevator cage 10 is further supported with guide elements 11, 12, 13, 14 at the guide rails 50, 60 extending in the vertical direction in the hoistway 20. The guide elements 11, 12, 13, 15 14 can comprise rolls rolling on the guide rails 50, 60 or glide elements gliding on the guide rails 50, 60 when the elevator cage 10 is mowing upwards and downwards. The guide rails 50, 60 are supported with support means 100 at the vertical side wall structures 21,22 of the hoistway 20. The support means 100 are situated on a suitable distance from each other along the run of the 20 guide rail 50, 60. The rolls or glide elements engaging with the guide rails 50, 60 keep the elevator cage 10 in position in the horizontal plane when the elevator cage 10 moves upwards and downwards in the hoistway 20. The guide rails 50, 60 can be formed of one single piece or of several consecutive guide rail elements positioned end to end one after the other. The counter weight 42 25 is supported in a corresponding way on guide rails supported on the vertical C\| ^ back wall structure 23 of the hoistway 20.

™ Fig. 2 shows a cross section of a first embodiment of a support C\1 v means according to the invention, figure 3 shows a cross section of a sheet of ^ the support element shown in figure 2, figure 4 shows a branch of the sheet I 30 shown in figure 3 and figure 5 shows the position of the openings in the stacked sheets in the support means. The support means 100 comprises in cö this embodiment only one support unit 110. The support unit 110 comprises five identical support sheets 111-115 being stacked together. Each support o w sheet 111-115 has essentially an L-shaped form. Each support sheet 111-115 35 comprises two openings 200 in each branch 111a, 111b of the letter L. The 5 openings 200 are oblong in the longitudinal direction of the branch 111a, 111b. The guide rail 50 is attached with fastening means 150, 151 to a first branch 111a of the support sheets 111-115 in the support unit 110. The second branch 111b of the support sheets 111-115 is fastened to the side wall 21 of 5 the hoistway 20 with fastening means 152, 153. The openings 200 in each branch 111a, 111 b in each support sheet 111 -115 are exactly in the same position as the sheets 111-115 are identical. There will thus be a slight deviation in the position of the openings 200 when the essentially L-shaped support sheets 111-115 are stacked to form the essentially L-shaped unit 110. This is 10 due to the thickness of the support sheets 111-115. The oblong form of the openings 200 ensures that there remains a through opening 200 through all of the sheets 111-115 when the support sheets 111-115 are stacked together. It is thus possible for the fastening means 150, 151, 152, 153 to pass through the openings 200 in the whole package of support sheets 111-115. The angle 15 a between the branches 111a, 111 b of the letter L in each support sheet 111-115 is advantageously 90 degrees. This support means 100 can be used in a situation where a 90 degree angle is needed in order to fasten the guide rail 50 to the wall structure 21 in the hoistway 20.

Fig. 6 shows a cross section of a second embodiment of a support 20 means according to the invention. The support means 100 in this second embodiment comprises two support units 110, 120. Each one of the two support units 110, 120 is identical to the support unit 110 shown in figure 2. The support units 110, 120 are attached to each other from one branch with fastening means 152, 153 so that the combined support means 100 has the form of a 25 lying letter U. The attachment of the guide rail 50 to the support means 100 corresponds to that shown in figure 2. The support means 100 is attached to 5 the side wall 21 in the hoitsway 20 by support means 154, 155 passing

C\J

^ through the openings 200 in the upper branch of the second support unit 120.

^ This support means 100 can be used in a situation where the guide rail 50 is to ^ 30 be fastened to a wall structure 21 behind the guide rail 50 in the hoistway 20.

1 Fig. 7 shows a cross section of a third embodiment of a support cd means according to the invention. This embodiment corresponds to the em- 2 bodiment shown in figure 6 except for the direction of the second support unit ^ 120. The direction of the second support unit 120 has been turned so that the ^ 35 combined support means 100 has essentially the form of a letter Z. This sup port means 100 can be used in a situation where there is a need to have the 6 fastening points of the support means 100 and the fastening points of the guide rail 50 non-aligned.

Fig. 8 shows a horizontal cross section of a fourth embodiment of a support means according to the invention. The support means 100 comprises 5 in this embodiment four support units 110, 120, 130, 140. The first support unit 110 is attached to the second support unit 120 with two fastening means 152, 153 passing through openings 200 in the corresponding branches of the support sheets 111-115, 121-125 of the first and the second support units 110, 120. The first support unit 110 and the second support unit 120 form together a 10 lying letter U. The third support unit 130 is attached in a similar way to the fourth support unit 140 with two fastening means 156, 157 passing through openings 200 in the corresponding branches of the support sheets 131-135, 141-145 of the third support unit 130 and the fourth support unit 140. The third support unit 130 and the fourth support unit 140 form together a lying letter U. 15 The second support unit 120 is further attached to the third support unit 130 with two fastening means 154, 155 passing through openings 200 in the corresponding branches in the support sheets 121-125, 131-135. The four support units 110, 120, 130, 140 form together two superimposed lying letters U. The two superimposed lying letters U open in the same direction.

20 The guide rail 50 is attached to a first branch in the first support unit 110 with two fastening means 150, 151 passing through openings 200 in the first branch of the support sheets 111-115 of the first support unit 110. The support means 100 is fastened to the wall structure 21 in the hoistway 20 with two fastening means 158, 159 passing through openings 200 in the upper 25 branch of the sheets 141 -145 of the fourth support unit 140.

The elevator cage 10 or the counter weight 42 can be supported 0 with rolls or glide means on the guide rail 50. The support can be from the op-

C\J

^ posite sides of the T shaped guide rail 50 and possible also from the front edge T of the T shaped guide rail 50.

^ 30 All the support sheets 111-115, 121-125, 131-135, 141-145 in the 1 support units 110, 120, 130, 140 are identical. The support sheets are thus co made from the same material, they have an equal width and thickness, the g branches of the L are equally long and the openings 200 are in the same posi- tion in both branches of the L. o ™ 35 The support means 100 in the embodiment shown in the figures comprises one, two or four support units 110, 120, 130, 140 but the support 7 means 100 could comprise any number 1, 2, 3, 4, 5 etc. of support units. The support units 110, 120, 130, 140 in the figures are used to support one guide rail 50, 60. The invention is naturally not limited to this. E.g. figures 6 and 7 could be amended to include a third support unit. The third support unit could 5 be fastened to the fastening means 152, 153 and directed in the opposite direction compared to the first support unit 110 i.e. forming a mirror image to the first support unit 110. Two guide rails 50, 60 could thus be fastened to a fastening means 100 comprising three fastening units and having two fastening surfaces for the guide rails 50, 60 and one fastening surface from which the 10 support means is fastened to the wall structure of the hoistway.

The openings 200 in the support units 110, 120, 130, 140 are positioned in such a way that it is possible to assemble the support units 110, 120, 130, 140 also cross wise so that two superimposed support units 110, 120, 130,140 are positioned at a 90 degree angle in relation to each other.

15 Each support unit 110, 120, 130, 140 in the embodiments shown in the figures comprises five support sheets 111-115, 121-125, 131-135, 141-145, but the number of sheets in each support unit can vary. Each support unit can thus comprise any number of support sheets. The minimum number of support sheets in each support unit is two. It is also not necessary that all sup-20 port units comprise the same number of support sheets. The number of support sheets can thus vary among the support units.

The support sheets 111-115, 121-125, 131-135, 141-145 in the support units 1110, 120, 130, 140 can advantageously be made of metal or of some other suitable material. The fastening means 150, 151, 152, 153, 154, 25 155, 156, 157 are advantageously bolts with nuts. The fastening to the side wall structures 21, 22 in the hoistway 20 can be done by drilling bores in the 0 side wall structures 21,22 and fastening with bolts and nuts.

C\J

^ The use of the support means 100 according to the invention is not ^ limited to the elevator shown in figure 1. The support means 100 can be used ^ 30 in any elevator having elevator guide rails e.g. in elevators having a machine 1 room and a counter weight as well as in elevators where there is no machine co room and/or no counter weight. The support means 100 can be used in the g guide rails 50, 60 guiding the elevator cage 10 and/or in the guide rails guiding the counter weight 42. The side wall structure 21, 22, 23 in the hoistway 20 00 35 can be e.g. a steel construction or a solid wall.

It will be obvious to a person skilled in the art that, as the technology 8 advances, the inventive concept can be implemented in various ways. The invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
