Specific embodiment

Hereinafter, being illustrated using attached drawing to the embodiment of the present invention.It should be noted that in the drawings, to identical Structure mark identical appended drawing reference, detail explanation is omitted for duplicate part.

[embodiment 1]

Firstly, being illustrated referring to Fig.1 to the lift appliance as object of the invention.Fig. 1 is the elevator of the present embodiment The sketch structure figure of device.

In the Machine Room 2 for being formed in the top section of liftway 1, there is the rope sheave for being wrapping with more main hoist cables 4 Hoist engine 3 is fixed on floor.One end of the main hoist cable 4 extended from the rope sheave via angle pulley 5 and balance weight 6 upper end Connection, also, the top of the other end of main hoist cable 4 and carriage 7 links.The car door 8 that can be opened and closed is provided in carriage 7, After carriage 7 rests against dock floor, car door 8 and stop door 32 are opened, and passenger is relative to 7 boarding of carriage.In car door 8 Lower side is configured with aftermentioned multiple openings 23.

It should be noted that in the present embodiment, as shown in Figure 1, using in the top of liftway configuration Machine Room The example of trail-type elevator is illustrated, but it's not limited to that for application range of the invention, and the configuration such as control panel is being risen It drops the tractor elevator of the machine House-less type in channel, wind elevator of winding drum type, the linear motor of hoist cable to reel (roller) Formula elevator etc. is also contained in the object of invention.

Fig. 2 is the perspective view for indicating the appearance of carriage 7 of the major part as lift appliance shown in FIG. 1.Carriage 7 exists Front side has the car door 8 of entrance, is provided with outside its top plate and has air inlet air blower and exhaust blower etc. Pneumatic controller 9.The Pneumatic controller 9 when carriage 7 is gone up and down in liftway 1, control air inlet air blower and Exhaust blower etc. carries out the pressurization and decompression in carriage 7, the variable quantity of air pressure per unit time remained it is constant, The sense of discomfort because of caused by air pressure change of the passenger in carriage 7 will not be brought.

The car door 8 that can be opened and closed is provided in carriage 7, which is the construction moved openingly and closingly while sliding, Therefore, even if also can cause to be based near the sliding part by the inside and outside connection of carriage 7 in the state that car door 8 is closed The pressure control efficiency of Pneumatic controller 9 reduces.Therefore, be formed as described below airtight near the car door 8 of carriage 7 Construction.It should be noted that car door 8 lower side be configured with along car door 8 short side direction be extended it is multiple Opening 23.

Fig. 3 is the partial sectional view for indicating the lower part of car door 8 of carriage 7 shown in FIG. 1.The distance pair as defined in separating The lower section between a pair of of board member 10a, 10b of configuration is set, the width direction both ends for extending to two board members 10a, 10b are sandwiched Portion is come the stiffener 11 that is formed and the bracket fixed plate 12 for the further lower section for extending to stiffener 11, and benefit It is fixed with bolt 13, thus constitutes car door 8.

In the lower part of car door 8 configured with car floor 14 and the carriage threshold 15 linked with car floor 14.Therefore, It is formed with opposed gap 16 between bracket fixed plate 12 and carriage threshold 15, is formed between board member 10b and car floor 14 Opposed gap 17.By opposed gap 16, the spatial portion 18 between two board members 10a, 10b and the left side as Fig. 3 will be formed in The external connection of the carriage 7 of square side is got up.In contrast, by opposed gap 17, by spatial portion 18 and as the right side of Fig. 3 Carriage inside connection get up.

The upper end of door boots bracket 19 with the width direction size roughly the same with bracket fixed plate 12 utilize along More horizontally arranged bolts 20 are fixed on the lower end of bracket fixed plate 12.It is configured at the door boots of the lower part of car door 8 21 are combined as a whole across opposed gap 16 and the lower end of door boots bracket 19.21 one side of this boots is along being formed in carriage threshold 15 guiding groove 22 slides, and can movably be embedded on one side.In this way, car door 8 is configured in door boots 21 by carriage threshold Movement is opened and closed while guidance in 15 (guiding grooves 22).

In above-mentioned bracket fixed plate 12, in the part for the adjacent upper part for being located at opposed gap 16, such as in aftermentioned part Detailed description forms multiple openings 23 like that.Using each opening 23 by spatial portion 18 and as the outer of the carriage 7 of the left side of Fig. 3 Portion's connection is got up.In addition, being configured in the opposed gap 17 being formed between the lower part of board member 10b and car floor 14 in sedan-chair It is capable of the gas check 24 in closed opposed gap 17 under the closed state of compartment door 8, is detailed in aftermentioned.

Fig. 4 is the enlarged drawing on above-mentioned 24 periphery of gas check.In the lower section of car door 8, extending as described above To the lower end of the bracket fixed plate 12 at the general width direction both ends of board member 10a, it is fixed with by along substantially water Square to more bolts 20 of configuration install door boots bracket 19.

It is formed near the door boots bracket 19 of bracket fixed plate 12 i.e. big in its longitudinal direction in the same manner as bolt 20 Cause multiple above-mentioned openings 23 discrete in horizontal direction.Each opening 23 is for being more energetically connected to the outside of carriage and being formed in Between spatial portion 18 between board member 10a, 10b.Determine size, shape, interval etc. of opening 23 so as not to because the opening 23 shape At and cause the mechanical strength of bracket fixed plate 12 to be greatly reduced.In bracket fixed plate 12, it is formed with the entirety of each opening 23 Width direction area size and gas check 24 longitudinal direction it is approximately equal in size.It should be noted that in Fig. 4, Gas check 24 is indicated with flexure member 25 and return portion 31.

It is preferred that near the upper end of door boots bracket 19 or in the bracket fixed plate 12 of part positioned adjacent along The upper end of door boots bracket 19 substantially discretely to form above-mentioned each opening 23 at equal intervals.It is respectively opened when being formed in such position It is able to carry out compensation when mouth 23, in order to avoid make because the lower side of door boots bracket 19 passes through due to opposed gap 16 is inserted by opposed The air-flow of gap 16 is affected, and finally makes a very bad impression to the movement of gas check 24.

That is, there is no each opening 23, by the air-flow in opposed gap 16 by door boots bracket 19 It interferes, the gas check 24 for being formed in opposed gap 17 as described later is affected.In the case where not forming each opening 23, Due to the influence of wind-force or wind speed by opposed gap 16, gas check 24 can not be deformed similarly in its longitudinal direction And cause to vibrate, chatter (abnormal noise) is generated near the part.

But as described above, formation will be between the outside of carriage 7 and the spatial portion being formed between board member 10a, 10b 18 The opening 23 of connection.Therefore, even if door boots bracket 19 is present in opposed gap 16, it is configured at the gas check 24 in opposed gap 17 (return portion 31) is also similarly acted by means of the air-flow of opening 23 in its width direction on the whole, is inhibited at the part Vibration, prevents the generation of chatter (abnormal noise).

It is described in detail also referring to infrastructure of the Fig. 5 to car door 8.Fig. 5 is the main view (A-A ' of board member 10a Direction direction view).Gas check 24 has flexure member 25 and return portion 31, they spread the width side of the lower end of car door 8 Pressurization to whole extension, and in the carriage 7 carried out with Pneumatic controller 9 shown in Fig. 2 and decompression correspondingly bullet Property deformation, and closed opposed gap 17 (referring to Fig. 4).In addition, gas check 24 is via the section shape with L-shaped and fixation It is bolted etc. in the bracket 26 of the lower end inside of board member 10b and is fixed on board member 10b.

Above-mentioned flexure member 25 has the return portion 31 in section substantially く shape of the inside of carriage 7 configured with bending part. The return portion 31 of section substantially く shape in flexure member 25 is configured to be formed between the lower part and car floor 14 of board member 10b Opposed gap 17 in Fig. 4 right side, that is, carriage 7 inside.The upper end of the flexure member 25 has necessary installation strong Degree, but the return portion 31 of section substantially く shape be formed to have can with Pneumatic controller 9 shown in Fig. 2 in carriage 7 plus Pressure and the flexibility for depressurizing correspondingly accessible flexible deformation.

Carriage 7 car door 8 close in the state of, when using Pneumatic controller 9 shown in Fig. 2 in carriage 7 into When row pressurization, in the opposed gap 17 between flexure member 25 and car floor 14, formed from the inside of carriage 7 towards outer effluent Dynamic air-flow.By at this time wind pressure and wind speed influenced, the open sides end extended of the return portion 31 of section substantially く shape and Opposed gap 17 is blocked, which becomes air-tight state.Later, by the differential pressure of the inner and outer of carriage 7, section substantially く The return portion 31 of shape keeps the state, keeps the air-tightness in opposed gap 17.

On the other hand, when using Pneumatic controller 9 shown in Fig. 2 to being depressurized in carriage 7, in flexure member 25 In section substantially く shape return portion 31 in the opposed gap 17 between car floor 14, formed from outside towards carriage 7 in The air-flow of side.At this point, the air-flow flowed into from the outside of carriage 7 is because being configured at opposed gap there is no opening 23 The presence of 16 door boots bracket 19 and be affected, therefore, it is possible to the return portion of the section substantially く shape in flexure member 25 Deformation is set to generate deviation in 31 longitudinal direction.

But as described above, multiple openings 23 are formed at a prescribed interval in bracket fixed plate 12, using opening 23 by sedan-chair The outside in compartment 7 is connected to the spatial portion 18 being formed between board member 10a, 10b.Therefore, 19 institute of a boots bracket is not will receive Caused baneful influence is integrally effectively formed from opening 23 in the longitudinal direction of the return portion 31 of section substantially く shape and passes through sky Between portion 18 and pass through the air-flow in opposed gap 17.

Thus, the return portion 31 of section substantially く shape is received through opposed gap 17 and is flowed into the wind of the air-flow in carriage 7 Speed and wind pressure, will not generate deviation in the longitudinal direction of the return portion 31 of the substantially く shape of the section in flexure member 25, and cut open The open sides end extended of the return portion 31 of face substantially く shape and block opposed gap 17, thus block air-flow.Later, by sedan-chair The differential pressure of the inner and outer in compartment 7 keeps the state, to keep the air-tightness in opposed gap 17.

Moreover, bracket fixed plate 12, which is configured to portion thereunder, is formed with discrete multiple openings 23 along longitudinal direction, Therefore, the mechanical strength of bracket fixed plate 12 will not be reduced.In addition, in bracket fixed plate 12 near door boots bracket 19 Opening 23 is formed, therefore, there is the directionality how not changed compared with the case where introducing air-flow from opposed gap 16, it can Form the air-flow towards opposed gap 17.

Therefore, for the return portion 31 of the substantially く shape of the section in the flexure member 25 of gas check 24, and out of carriage 7 Deformation caused by air-flow outside similarly can effectively become by the external air-flow inside from carriage 7 Shape.Thus, the directionality of air-flow can efficiently and securely make section substantially く shape under any circumstance there is no deviation Return portion 31 deforms, to obtain the airtight construction of high reliablity.

It should be noted that if opening 23 is undersized, then the pressure loss becomes larger and is difficult to be formed air-flow, another party Face becomes smaller and though wind is made to pass through wind speed to the application of the flexure member of gas check 24 25 if opening 23 is oversized Wind-force becomes smaller, it is therefore preferable that these to be taken into account to size, shape, the interval etc. to determine opening 23.

In the lift appliance with Pneumatic controller of Fig. 2, gas check 24 is set, to make carriage 7 at runtime Airtightization and carry out pressure control.Car door 8 is configured to that movement is opened and closed while sliding, therefore, the gas check 24 Airtight construction can not be formed in the on-off action of car door 8 and becomes open state, on the other hand, utilized at runtime because of pressure The air-flow that power is poor and generates forms air-tight state.

In this lift appliance with Pneumatic controller, the above-mentioned Pneumatic controller 9 in elevator maximum speed It is controlled such that the internal and external pressure difference of carriage 7 becomes smaller, therefore, if the airtight retentivity of gas check 24 reduces, at this Part generates the opposed gap 17 of the flowing with air-flow, and the outer noise of carriage enters from the opposed gap 17, making an uproar in carriage 7 Sound increases.

But according to the present embodiment, as described above, not will receive the shadow for being configured at the door boots bracket 19 in opposed gap 16 It rings, opening 23 can be passed through and be effectively formed air-flow.Therefore, the gas check 24 in opposed gap 17 is configured at relative to carriage 7 Interior barometric fluctuation responsiveness becomes airtight conditions well, can readily insure that the airtightness in carriage 7.Thus, it is possible to It effectively shields the generation of chatter (abnormal noise) or enters from external noise.

In addition, in a preferred embodiment, the lower part for being configured to 19 side of door boots bracket in bracket fixed plate 12 is formed Multiple openings 23, by adjusting its size, quantity, interval etc., will not reduce the mechanical strength of bracket fixed plate 12.Moreover, sharp With opening 23, there can be the directionality how not changed compared with the case where introducing air-flow from opposed gap 16, form court To the air-flow in opposed gap 17, therefore, the return portion 31 of the section substantially く shape in the flexure member 25 of gas check 24 can be made It efficiently and securely deforms, to obtain airtight construction.

On the other hand, it is also considered that formed and be open in door boots bracket 19, but as the narrow place as opposed gap 16 Using and make a boots bracket 19 mechanical strength reduce or other structures are impacted.In contrast, when solid in bracket When the lower section of fixed board 12 forms opening 23, door boots bracket as in the past is used as door boots bracket 19, carriage can be made The door boots 21 of the lower end of door 8 are good along the guiding groove 22 for being formed in carriage threshold 15 and reliably move, and can lead to Cross the lift appliance that simple structure obtains the airproof of high reliablity.

It should be noted that in the present embodiment, as gas check 24, Fig. 3 and structure shown in fig. 5 are instantiated Gas check, but also it is able to use the airtight dress that the other structures of air tight construction are obtained using the air-flow flowed in opposed gap 17 It sets.

As described above, lift appliance of the invention forms opening 23 in bracket fixed plate 12, which uses The roughly the same gas of the deformation in the longitudinal direction for making flexure member 25 is formed towards gas check 24 in the outside from carriage 7 Stream.

According to this structure, it even if configuring door boots bracket 19 in opposed gap 16, can also be formed by opening 23 Stable air-flow keeps the deformation in the longitudinal direction of flexure member 25 roughly the same, is reliably prevented from because in flexible structure The longitudinal direction of part 25 can not integrally obtain the vibration for being uniformly deformed into the flexure member 25 of cause and generate chatter (exception The sound) or noise is made to enter the inside of carriage 7 from the outside of carriage 7.

In addition, the present invention is on the basis of above-mentioned structure, in 19 side of door boots bracket of bracket fixed plate 12, along opposed The longitudinal direction (short side direction of car door 8) in gap 16 discretely forms multiple openings 23.

According to this structure, the mechanical strength of bracket fixed plate 12 will not be made extremely to reduce because forming opening 23, edge Opposed gap 16 longitudinal direction formed it is multiple opening 23, the deformation substantially phase in the longitudinal direction of flexure member 25 can be made Together.

In addition, the present invention, on the basis of above-mentioned structure, flexure member 25 has in the inside of carriage 7 configured with bending The return portion 31 of the section in portion substantially く shape.

According to this structure, carry out carriage 7 in pressure control lift appliance in, can effectively capture in order to The air-flow for carrying out the pressure control in carriage 7 and generating, deforms the return portion 31 of section substantially く shape reliably, to obtain Air-tight state.

It should be noted that the present invention is not limited to the above embodiments, including various modifications example.For example, above-mentioned Embodiment is for ease of understanding to illustrate the present invention and be described in detail, but be not necessarily limited to the whole knots for having illustrated Structure.A part of the structure of a certain embodiment can be substituted for the structure of other embodiments, and also can be in a certain implementation The structure of additional other embodiments in the structure of example.In addition, a part of the structure of each embodiment can be added, be deleted, Replace other structures.
