Description

The escalator step equiped with the brush-type demarcation}

The present invention provides a step having a constant width between a guardrail that maintains a constant space and a skirt guard, which is a fixed passage under the railing, in a passenger transportation equipment such as an escalator and a moving walker. Step) to prevent accidents that occur when part of the user's body or shoes are caught in the gap between the step and the skirt guard in a structure that operates while maintaining a constant clearance with the skirt guard. It is about.

Due to the increase in the size of the building and the development of technology, escalators and automatic walkways have increased in number of installations, and the occurrence of various safety accidents is increasing.

Among them, accidents during the operation of the escalator are frequent, especially accidents caused by part of the human body or the attachment of human body such as shoes in the gap between the step and the skirt guard are not only frequent, but once the accident occurs, the degree of injury is fatal.

This accident is caused by the structural problem of the escalator. The skirt guard, which is the moving passage of the railing and the step of the rail, is fixed while the step must move continuously to transport the user. There is a legal gap of 4mm.

If this part of the human body is caught by hands, shoes, or long hem, it is sucked deeper by the rotational force and friction and is cut in a place called a comb, a fixed body where the step is caught between the step and skirt guard or the step enters the lower part of the escalator. Injury caused by the effect will be generated.

Due to this problem, conventionally, a step of making and installing a step by inserting a plastic material called yellow demarcation, which is a warning color, in a predetermined width at four corners of the step is called attention, but it prevents an accident or It does not reduce significantly.

In addition, US Pat. No. 6,405,847 is installed to prevent an accident by attaching a separate part called a safety brush to the upper skirt guard wall of the escalator step as a method of preventing an accident of this part. There is an inconvenience in operation due to interference in the step, and the situation between the step and the skirt guard is not much improved, so there will be a lot of functional shortages that cannot prevent the shoes from being structurally caught.

In addition, according to the published patent (Publication No. 10-2006-0055377), the brush mounted on the step is installed vertically, the noise caused by scratches on the skirt guard due to the bristles bent sideways by stepping on the user's foot or pressed by the cargo, etc. And scratches on the surface of the skirt guard scratches the aesthetics, and there is a disadvantage that the risk factors that are caught in the skirt guard and the comb on its own bristles widening the moment you enter the fixed comb.

In addition, when the escalator is operated, the bristle brushes installed on the riser are widened at the point where the step-shaped steps change horizontally or horizontally from the upper and lower steps of the escalator. There are disadvantages that can be dangerous.

Therefore, the patent discloses a problem in which the brush needs to be replaced periodically to solve the above problem when the brush is installed at a time when the brush is opened.

In other words, there is a method of mounting a vertical brush on the destructive part of the US patent and the US patent, which is used as a method for preventing accidents caused by the clamping between the conventional step and the skirt guard. Another problem occurs such as inconvenience of care and pinching of the brush itself.

The present invention is an invention for preventing the accident between the escalator step and the skirt guard as described above, and the problem that the conventional safety device is expensive in the installation and the regular replacement cost in operation and Its purpose is to provide a way to fundamentally resolve a jamming incident without causing operational inconvenience.

Therefore, according to the present invention for solving the above problems,

In the step of the escalator, it faces the skirt guard and has the same height as the top of the step cleat, the thickness of the brush can be inserted and fixed horizontally to the step, and the bottom of the brush extends to the step end for fixing the demas " Degassing body having a "b" shape, the degassing body has a length corresponding to the step width and a plurality of brushes are inserted and fixed at all lengths parallel to the step to form a body.

Brushes with brushed demas can be attached to the step at a fixed or mixed angle from 0 ° (horizontal) to 15 °,

By applying the brush-type demas according to the above embodiment to the step riser portion facing the skirt guard side may be applied to the escalator downward to prevent the jamming accident.

In the comb of the escalator is fixed to the upper and lower parts of the escalator to remove foreign substances in the cleat groove between the cleats of the step, and to move smoothly to the comb in which the movable step is fixed,

There is no comb comb teeth with brush-shaped demarcation width of the same height as the cleat of the step, and the comb comb for the brush type demas is applied to the remaining space with a comb comb corresponding to the existing step cleat and the cleat groove.

According to another embodiment, the escalator step brush type descaling is applied to reduce the risk of jamming by preventing the shoe from approaching the skirt guard because the descaling body is made thicker and higher than the step cleats. As an escalator comb for a corresponding degassing body, there is no comb comb as much as the width corresponding to the brush-type portion, and the body portion is made high so that it is installed on the escalator with the brush type demas.

According to another embodiment, the auxiliary comb corresponding to the brush type descaling of the escalator step and the auxiliary cleat of the brushed descaling are formed on the descaling body of the brush type descaling. Brush-type comb for having each will be installed on the escalator in a pair.

According to another embodiment, a safety space such as a straight line or a round shape for forming a safety space in the degassing body under the brush of the brush type degassing is formed to be safe even if clothes or shoes are sandwiched between the brush and the skirt guard. It is characterized by double prevention of pinching due to the difficulty of inserting more space,

According to another embodiment, the angle between the vertical surface of the inner portion of the brush-type degassing body and the corner of the horizontal plane is an obtuse angle of 93 ° or less, and the brush-type degassing is fixed by screwing the screw 70 to the lower surface of the descaling body. Because of the stronger adhesive force, the brush body on the skirt guard side has a strong adhesive effect without lifting on the stepper.

In addition, it is possible to have a structure to reduce the material by forming a groove of a predetermined size in the lower portion of the degassing body.

According to another preferred embodiment, the brush body of the brush-type degassing does not have a degassing body of the brush type of "ㅁ" type, the step edge portion of the brush lower portion of the brush of the "ㅁ" type It is possible to secure the above safety while saving material by providing a step structure that forms a safety space having a slope-like surface.

In addition, by applying the brush-type demas and comb comb of the various embodiments described above to the step and the comb for the automatic walkway to provide a comb for the brush press and demas for the automatic walkway, step and skirt guard of the escalator and automatic walkway Provides a safety device with a feature that prevents accidental jamming in the gap between them.

The present invention of the above configuration is the main cause of the escalator and automatic sidewalk and once the accident occurs has the effect of preventing the jamming of the step leading to a large accident at its source.

In addition, the structure of the present invention does not add a separate installation cost like a safety brush for attaching a skirt guard for preventing step pinching, and there is no additional cost by changing the structure of a step, which is a component of an escalator, and when installing or dismantling a step. There is also a feature that does not cause inconvenience to users or equipment operators during operation.

In addition, there is no need to replace the brush because the brush itself is worn or interference.

Escalator is a device installed in the building to transport the user up, down or horizontally, briefly explaining the structure, the truss for supporting the weight of the escalator itself and the user to the building, fixed in parallel to both sides of the truss Steps 100 are fixed and installed on the step chain over the entire length of the upper and lower parts of the escalator, and the step chain is fixed to the truss. The user is transported by moving in a constant trajectory along the step chain rail, and the step chain is connected to the motor and the reducer by a driving chain, and the driving force is transmitted to each sprocket to rotate the step chain, which is fixed to the step chain. Step roller 30 of the step is rotated in a constant trajectory to transport the user boarded on the step

The skirt guard 90 is fixedly installed on both sides of the escalator to maintain a constant width according to the escalator capacity, the escalator step 100 is the skirt guard 90 and the gap at one side is 3 ~ 4mm and the total of both gaps. It is prescribed within 7mm.

In addition, the escalator comb 60 is fixed to the frame of the upper part of the truss is connected to the plurality of steps to the width of the step is installed on the part of the escalator, the step is transferred to the inside and exit the escalator.

Although the upper part of the escalator step 100 is generally flat, the cleat 50 is formed with a predetermined width and depth at a length corresponding to the width of the step, and a cleat groove is formed between the cleat and the cleat, so that the step 100 has an uneven shape in the entire length. Is formed.

Escalator comb 60 is comb comb 63 and comb spacing in the comb body so that comb teeth 63 do not contact the cleat 50 in response to the cleat groove 64 and the cleat groove 64 of the step It is installed to protrude so that the step 100 is transferred and enters the comb 60, which is a fixed body on the escalator, so that the user on the step can be safely used without being caught and removes foreign substances between the step cleat grooves 64. It also plays a role.

The escalator steps are fixed to the step chain and moved by the step rollers 30 along the step rails to transport the user, so that a part of the human body, a hem or rubber material is placed in the gap with the skirt guard 90 on both sides of the step 100. In the case of thin slippers, large accidents are easily caught by the gaps.

Exemplary embodiments of the present invention for solving the above problems will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view illustrating an assembly state of a conventional step, an escalator railing, and a skirt guard 90. As shown in FIG. 1, an assembly state of a fixed railing and a step moving into the skirt guard 90 can be seen.

2 is a plan view 101, a front view 102, and a right side view 103 seen from the right side of the step in a conventional step view.

The irregularities are formed at regular intervals by the cleats 50 having a predetermined width and depth on the scaffold 10 and the riser 20, which are the upper portions of the step 100, and the step 100 is located on the right side of the front view 102. It can be seen that the gap between the skirt guard 90 and the) is formed.

The gap is usually made of iron plate, when the fixed side of the skirt guard 90 is fixed to the aluminum alloy that runs while maintaining a constant interval or when the sticking 40 is attached to the step 100 of the hardened plastic material If a part of the human body or an attachment such as a shoe is placed in the gap, the slippage effect is caused by the friction between the skirt guards 90, which leads to the effect of being sucked deeper. When the escalator moves upward, the step 100 is upper. If the accident occurs in the gap of the side and the driving down will cause the accident in the step riser 20.

However, when a person uses an escalator, the accident occurs more frequently in the step upper footrest 10 than in the riser 20 part far from the human body because the user climbs and uses the upper part of the step 100.

As described above, in order to explain in detail the characteristics of the present invention for generating a jamming accident generated in the gap between the skirt guard 90 on both sides of the escalator and the step 100, the cause of the jamming accident at the step is more detailed. In other words, when a part of the human body or an attachment such as a shoe is placed at the end edge of the step and contacts the skirt guard 90 surface, the edge of the step 100 is relatively fixed and the friction is pushed downward from the skirt guard surface. This causes the human body or attachment to be swept downwards, that is, into the gap, and when the swept away portion is wider than the gap between the step and the skirt guard, the frictional force increases and the body or attachment is sucked more. In extreme cases, the step may be broken or develop into an audible accident.

This problem can be completely solved in the brushed desmaption 80 according to the present invention. FIG. 3 is a plan view 104 and a front view of the step of the escalator step 110 according to the present invention. 105) and a right side view 106 seen from the right side.
Escalator according to the present invention is provided on the step formed on both sides of the step 110, the skirt guard 90 side and provided to have the same height as the step cleat 50, the brush 82 on one side And a demolition body 83 having a thickness that can be inserted and fixed.

And the degassing body 83 is formed in a "b" form, one side of the degassing body 83 extends to the end of the step 110 for fixing with the step (110). In particular, the upper surface of one side of the extended degassing body 83 is formed to be inclined upward in the direction from the step 110 toward the skirt guard 90, the brush 82 inserted and fixed to the degassing body 83 is step ( It is inserted and fixed inclined upward in the direction from the 110 to the skirt guard 90.

Conventionally, if a human body attachment such as shoes is caught in the skirt guard 90 and the body of the step 100 or the skirt guard 90 and the plastics demas 40, the two bodies are stronger than the human body or the attachment. Or the attachment continued to be sucked in, damaging the human body or the attachment, and eventually causing a personal injury.

In the case where the brush-type dermabrasion 80 according to the present invention is mounted at the step 110, even if the human body or the attachment of the human body is sandwiched between the skirt guard 90 and the brush-type demas 80, the thickness of the brush 82 is increased. If the body is caught by the corresponding depth, the human body feels dangerous and immediately pulls out the body to prevent the accident, and even if the attachment is caught, the brush-type degassing (80) must be lowered to a depth deeper than the thickness of the brush (82). Only until the hard brush-type degassing body (83) is lowered, the accident occurs by the friction force and the pressing force will not occur until the deliberate insertion.

In addition, according to another preferred embodiment, the brush 82 of the brush-type demas 80 may be provided with a brush 82 at a constant or mixed angle to be upward from the horizontal of 0 ° ~ 15 °.

In particular, when the brush 82 is installed upward, even if a human body attachment such as clothing is caught between the skirt guard 90 and the brush 82, the brush 82 is bent downward and the elasticity of the brush itself is caused by the stuck attachment. It is effective to prevent jamming accidents by pushing it out.

4 is a brush type degassing 81 applied to the riser 20 on both sides of the step 110 and applied to the brush type demarcation 80 on both sides of the step foot 10. When the escalator is operated in the same direction as the same, there is a feature to prevent the accident of the riser 20.

FIG. 5 is a view illustrating a brush-type demarcation 80 applied to the step scaffold 10 and a comb 60 provided at upper and lower portions of the escalator corresponding to the step scaffold 10. Comb comb (3) is formed on the portion facing the (10), but the comb teeth (63) because there is no cleat (50) and the cleat groove (64) in the brush-type demas (80).

6 is attached to the step 110 by attaching the brushed demas 80 higher than the height of the cleat 50 of the step 110 to the skirt guard 90 position where the user may be caught in the step. If the height is increased so as not to approach as much as possible, when the user climbs the step 110 and the shoe is caught by the high demarcation 84, or the declining 84 is stepped on, the step cleat 50 and the demarcation 84 are written. It is inconvenient to stand because the height difference between the two and the stand to reduce the access to the skirt guard 90 side to prevent more accidents, escalator corresponding to the brush-type demas 84 higher than the step cleat (50) As the comb 61, as shown in FIG. 5, the comb teeth 63 having the same shape as the conventional comb are provided on the part without the brushed demas, but the comb 61 and the demas are formed on the brushed desmaption portions 80 and 84. FIG. 84 contacts In order to not provide a comb (61) in the form of a comb to create a high body (65).

FIG. 7 shows the cleat groove and the auxiliary cleat 67 formed in the comb body with the width and depth possible for the demolition body portion of the brushed demas 80 and 84 higher than the cleat of FIG. Applying the comb 66 to the brush-type demas (80, 85) and the comb 62 of the brush-type demas (80, 85) and features that can ensure more safety when passing through the comb (62) of the stationary body It is characterized by providing.

8-14 are various cross-sectional details of a preferred brushed demarcation 80.

FIG. 8 is a cross-sectional view of the brush-type desalinations 80 and 83 having the same height as the step cleats, and the brush 82 is formed by attaching the degassing body 83 to the “b” shape and attaching it to the step. In FIG. 83, a human body attachment such as a hem is attached to the upper portion of the brush 82 by applying an inclination of about 4 ° upward in the direction of the skirt guard 90 at the brush 82 and the skirt guard 90. When entering into the gap between the brush 82 is bent downwards to the upward elasticity is to act to prevent falling further down.

9 and 10 further show an auxiliary cleat 67 and a cleat on the destructing body 84 of a brushed demas higher than the step cleat 50 and of a brushed demas higher than the cleat 50. It is the cross-sectional detail which applied the groove.

11 shows a descaling body 83 of a hard material under the brush when the human body or the attachment of the human body is placed on the brush 82 of the brush-type desmaising 80 and then inserted under the brush 82 in a certain situation. Cross section detail of a preferred embodiment of the brush-type demas (80, 86) secured a safety space because the conventional gap condition is formed between the degassing body (83) and the skirt guard (90) there is a risk of jamming accident to be.

In summary, the brush-type desmaption 80 of the preferred embodiment according to the present invention, a user wearing a shoe of rubber material on the escalator step 110 and wearing a pants or skirt attracted to the step 110 due to a long hem. If you step up and stand on the step, the brush 82 of the brush-type dedication 80 puts the pants or skirt down into the gap between the brush 82 and the skirt guard 90, but the brush is hard. Since it is not a material, there is an effect that a continuous pinching phenomenon in friction and narrowing with the skirt guard 90 does not occur.

In addition, the brush type demas (80, 84) higher than the cleats (50), when the shoes stand toward the skirt guard, the demassion is high and the rest of the lower parts are inconvenient to stand, thus preventing the access to the gap between the skirt guard and pinching the shoes. Significantly decreased.

In addition, even if the playful user deliberately pushes the shoes or feet toward the skirt guard 90 and the shoes or clothes are pushed down to the bottom of the brush 82, the jamming body 86 or the step ( 86) It is an impossible level of safety to go down to wealth.

12 is a cross-sectional detail view of yet another preferred embodiment of the brushed desmaption 80, in which the screw 70 is tightened to the desorption body 83 and the step 110 to secure the brushed desorption 80. FIG. If the fixing body 83 is firmly tightened to the step 110 and fixed, the step end of the skirt guard 90 side and the end of the brush type destructing 83 do not come into close contact with each other. Excited gap may occur, a part of the brush removed by this gap or other foreign matter is caught in a hard object or the condition may be damaged because the demastion to provide a structure for preventing this,

Deformation on the skirt guard 90 side when the fixing screw 70 is tightened to form an obtuse angle within 93 ° of the lower inner corner of the brushed desorption body 87 to fix the brushed desorption 87. If the body 87 is in contact first and then continue to tighten the screw 70, the edge of the desizing body 87 is tightened later, there is an effect that the lifting gap does not occur at the end.

Of course, the angle of the obtuse angle is changed according to the material characteristics of the degassing body 87, and should be appropriately applied. In the case of a material having good ductility and elasticity, the angle is larger, and the material having a small ductility and elasticity is close to 90 °. Should be applied.

FIG. 13 is a cross-sectional detail view of the brush-type desmear 88 having a space for saving material when the body of the brush lower part of the brush-type demas 80 is thick, and at least 50 to 60 steps are included in one escalator. When applied to both sides and the quantity of production increases, material saving is also an important factor, so it is necessary to reduce the input amount of material within the limit that the strength of brush type demas is maintained, and in order to achieve the purpose, It is a demas formed in the lower part of the 88 to form a space 88 for the material saving.

Fig. 14 removes the degassing body under the brush 82 of the brushed degassing 80 and 89 to take the "b" shape as the degassing body 89 of the "ㅁ" shape and the lower part of the brush 82 is a step. It is a (110) plane and is characterized in that the inclined safety space 86 is applied to the corner of the step itself at the lower portion of the brush 82 to ensure safety.
