Description

  The present invention relates to a balustrade panel attached to a balustrade of a passenger conveyor.

  In passenger conveyors, for example, escalators, balustrades are installed on both sides of steps that are connected in a circular manner and circulate (for example, Patent Document 1). The balustrade has a plurality of balustrade panels erected along the running path of the steps. Each balustrade panel is held in an upright position with its lower end held between panel holding members fixed to the truss. As the balustrade panel, in recent years, the emphasis is on design, and a glass balustrade panel (hereinafter simply referred to as “glass panel”) in which an anti-scattering film is attached to both sides or one side of a glass plate is often used. ing.

  In the escalator which consists of the said structure, the balustrade panel, ie, a glass panel, bears most of the intensity | strength and rigidity of the whole balustrade. Therefore, if the glass panel breaks, such as cracks, the necessary strength of the entire balustrade may be insufficient. For safety reasons, the escalator operation is temporarily stopped and the broken glass panel is removed as soon as possible. It is desirable to replace it. In particular, in large-scale commercial facilities, escalators play an important role as one of the main traffic flow of visitors, so restoration work is required as quickly as possible. At this time, if a replacement glass panel is always stocked as a supplementary item, it is considered that the time required to restore operation of the escalator can be shortened as much as possible.

  However, glass panels are expensive and are often handled as made-to-order products rather than spare parts with a large stock burden, for example because it is impossible to know the timing of breakage. For this reason, until now, replacement glass panels have been prepared, and repairs of damaged parts of existing glass panels with adhesive tape such as gummed tape and emergency repairs such as pasting a reinforcing member such as plywood are performed. In such a state, measures are taken such that the escalator is temporarily restored. In such a measure, the emergency repair site is directly visible from the surrounding visitors and passengers, which is not preferable from an aesthetic point of view.

  The above-mentioned problem is not limited to the parapet of the escalator that transports passengers by an endless transport body composed of a plurality of steps connected in a ring shape, but is a passenger conveyor having an endless transport body of another type, for example, a rubber belt type endless transport body. It is also common to certain "moving sidewalk" railings.

JP 2011-173711 A

  The present invention has been made in view of the above problems, and it is an object of the present invention to make it possible to perform a temporary restoration operation of a passenger conveyor without causing an increase in the stock burden of the balustrade panel and without damaging the beauty as much as possible. .

  The present invention relates to a passenger conveyor having a plurality of balustrade panels erected along a traveling path of an endless carrier that circulates and conveys passengers, and a temporary balustrade that can be replaced with any of the plurality of balustrade panels. It is a panel, and both main surfaces of the main body panel having the same shape as the main surface of the balustrade panel to be replaced are subjected to a cosmetic treatment, and have the same thickness as the balustrade panel.

  In the temporary balustrade panel of the present invention, the main body panel may be made of a wood board.

  In the temporary balustrade panel of the present invention, a decorative sheet may be provided on each of the main surfaces of the main body panel as the decorative treatment.

  In the temporary balustrade panel of the present invention, the decorative sheet may be made of a thin metal plate.

  According to the temporary balustrade panel having the above configuration, since it has the same shape and thickness as the existing balustrade panel, the temporary restoration operation of the passenger conveyor can be performed in a state where the damaged balustrade panel is replaced with the temporary balustrade panel. Is possible. Since both main surfaces of the main body panel constituting the temporary balustrade panel are subjected to a cosmetic treatment, even if directly viewed from a passenger using the passenger conveyor, the aesthetic appearance of the passenger conveyor is not impaired as much as possible. It is possible to perform a temporary restoration operation. In addition, even if each of the existing balustrade panels includes a different shape, it is sufficient to stock temporary balustrade panels corresponding to the balustrade panels to be replaced. This will not lead to an increase in the stock burden of regular balustrade panels used in the factory.

It is (a) side view and (b) top view which show schematic structure of an escalator. It is sectional drawing cut | disconnected along the (a) side view and (b) AA line of the temporary balustrade panel which concerns on embodiment. It is a side view of the said escalator which is temporarily restored by the state where the said temporary balustrade panel was attached.

  Hereinafter, an embodiment of a temporary balustrade panel according to the present invention will be described with reference to the drawings, taking as an example a case of being used for a balustrade of an escalator.

  As shown in FIG. 1, the escalator 1 includes a plurality of steps 2 that are endless transport bodies that are connected in a circular manner and circulate. The balustrades 3 and 4 (not shown in FIG. 1A) are installed on both sides of the traveling step 2.

  A glass panel 5, which is a plurality of balustrade panels, is erected on the balustrade 3 along the travel path of the steps 2. Each of the glass panels 5 includes glass panels 5a, 5b, and 5c having different main surface shapes. Hereinafter, when the glass panels 5a, 5b, and 5c are distinguished from the reference numerals, the shape of the main surface is the same as that of the specific glass panel or the glass panel attached with the reference numerals in FIG. I will refer to things. Each of the glass panels 5 is held in an upright posture in a state where the respective lower ends are sandwiched by a panel holding member (not shown) fixed to a truss (not shown). A plurality of glass panels (not shown) are also erected on the balustrade 4 in an upright posture along the travel path of the steps 2, as in the balustrade 3.

  On the outer periphery of each glass panel 5, endless moving handrails 6 and 7 (not shown in FIG. 1 (a)) that are circulated while being guided by guide rails (not shown) are provided. The moving handrails 6 and 7 are guided to move in the horizontal direction in the upper and lower end regions of the escalator 1 in synchronization with the travel of the step 2, and are guided to incline between the both end regions. The The plurality of steps 2 and the movable handrails 6 and 7 connected in an annular shape are driven via a power transmission mechanism (not shown) using the motor 8 as a power source. The operation stop of the motor 8, the safety device (not shown) and other general operation operations of the escalator 1 are controlled by the control unit 9.

  The escalator 1 is installed between the lower floor DS and the upper floor US in the building, and each of the steps 2 connected in a ring shape is indicated by an arrow in FIG. Circulate in the direction shown. The escalator 1 of this example is used for ascending purposes, and passengers on the steps 2 are carried upstairs from the downstairs.

  In the escalator 1 configured as described above, breakage such as cracks may occur in any of the glass panels 5. The cause of the damage is various, for example, natural destruction of glass (so-called “self-destruction”), impact destruction by applying some external force to the glass (for example, impact received from passenger's body or baggage), and the like. In this case, as described above, the escalator 1 is temporarily restored until a new glass panel 5 to be replaced with a damaged one is prepared.

  Hereinafter, the temporary balustrade panel 10 (FIG. 2) according to the embodiment will be described on the assumption that the glass panel 5 denoted by reference numeral “5a” in FIG.

  The temporary balustrade panel 10 of this embodiment is replaced with a damaged glass panel 5a during the temporary restoration operation. As shown in FIG. 2, the temporary balustrade panel 10 includes a wooden plywood 11 which is a main body panel having the same rectangular shape as the main surface of the glass panel 5a to be replaced. On both main surfaces of the plywood 11, stainless steel thin plates 12 and 13, which are decorative sheets, are provided over the entire surface of each main surface as a decorative treatment. That is, the temporary balustrade panel 10 is composed of a composite panel having a sandwich structure in which a plywood 11 is sandwiched between a pair of thin metal plates 12 and 13, and the plywood 11 and the thin metal plates 12 and 13 are bonded to each other (not shown). It is pasted through.

  The temporary balustrade panel 10 has the same thickness as the glass panel 5a to be replaced. Specifically, the total thickness of the panel obtained by adding the thickness t1 of the plywood 11, the thickness t2 and t3 of each of the pair of thin metal plates 12 and 13, and the thickness of the adhesive layer (not shown) is the glass panel 5a. It is designed to be equal to the thickness. By setting it as such a structure, when replacing the temporary balustrade panel 10 with the glass panel 5a, the existing part currently used for attachment of the existing glass panel 5a is used as it is, and the temporary balustrade 3 is comprised temporarily. It can be attached as a part.

  In addition, the outer peripheral side surface of the temporary balustrade panel 10 does not necessarily have to be subjected to the cosmetic treatment, and the plywood 11, the pair of metal thin plates 12, 13 and an adhesive layer (not shown) formed between them are provided. Each laminated surface (FIG. 2B) may be exposed. In the balustrade 3, when the glass panel 5 a is replaced with the temporary balustrade panel 10, the outer peripheral side surface of the temporary balustrade panel 10 is not visible or difficult to be seen by visitors and passengers around the escalator 1. This is because it does not affect the appearance of the. Thereby, it becomes possible to aim at reduction of material cost, processing cost, etc. by simplification of composition, and the temporary balustrade panel 10 can be obtained at low cost.

  The procedure for attaching and removing the temporary balustrade panel 10 to and from the balustrade 3 is the same as the procedure for attaching and removing the glass panel 5a to and from the balustrade 3 which has already been performed as the restoration work, and thus the description thereof is omitted. I will do it.

  FIG. 3 shows an external view of the escalator 1 that has been temporarily restored in a state where the glass panel 5a of the balustrade 3 is replaced with the temporary balustrade panel 10. In the temporary balustrade panel 10 attached to the balustrade 3, it is the portions of the thin metal plates 12 and 13 that are directly visible from the visitors and passengers around the escalator 1. On the other hand, all balustrade panels other than the temporary balustrade panel 10 are made of existing glass. For this reason, when paying attention to only the balustrade panel in the balustrade 3, only the part to which the temporary balustrade panel 10 is attached has a different appearance from the other parts.

  However, metal parts such as stainless steel are often used for other parts of the balustrade 3 (for example, a known outer deck, inner deck, handrail guide rail, etc.), and the appearance of the temporary balustrade panel 10 And has a common texture. Therefore, when viewed as the overall appearance of the balustrade 3, the discomfort in the appearance is reduced as compared with the conventional emergency repair site. As a result, the extent to which the aesthetics of the escalator 1 during temporary restoration operation is impaired can be suppressed.

  Thus, according to the temporary balustrade panel 10 of this embodiment, since it has the same shape and thickness as the glass panel 5a which is an existing balustrade panel, even if the glass panel 5a is damaged, the glass panel 5a is temporarily installed. It is possible to perform a temporary restoration operation of the escalator 1 in a state where the balustrade panel 10 is replaced. Since both main surfaces of the plywood 11 which is a main body panel constituting the temporary balustrade panel 10 are subjected to a cosmetic process such as attaching thin metal plates 12 and 13 made of stainless steel, the temporary balustrade panel 10 is attached. It is possible to reduce the uncomfortable feeling on the appearance of the balustrade 3. Therefore, even if the temporary balustrade panel 10 is directly visually recognized by a passenger or the like who uses the escalator 1, it is possible to perform the temporary restoration operation without impairing the aesthetics of the escalator 1 as compared with the conventional case.

  Moreover, since the temporary balustrade panel 10 is comprised from the composite panel which makes the sandwich structure which pinched the plywood 11 between a pair of metal thin plates 12 and 13 as mentioned above, it consists only of the plywood 11, for example. Compared to the case, the strength and rigidity of the entire panel are reinforced by the thin metal plates 12 and 13. Thereby, in performing the temporary restoration operation of the escalator 1 using the temporary balustrade panel 10, until the regular glass panel 5a used at the time of this restoration is prepared, there is no problem in safety. The strength and rigidity can be held in the balustrade 3.

  Furthermore, since the temporary balustrade panel 10 occupies most of the volume by the wooden plywood 11, the metal thin plates 12 and 13 made of a metal material having a specific gravity greater than that of the wood are merely decorative sheets having a small occupied volume. It is lighter than the panel 5a. In addition, since the temporary balustrade panel 10 is less likely to be damaged during the transportation or attachment / removal work to the balustrade 3, even if it is handled rougher than the glass panel 5 a, there is no problem. For this reason, the work load per worker can be reduced, workability for temporary restoration can be improved, and consequently the time required for starting the temporary restoration operation of the escalator 1 can be shortened. it can.

  In the above description, it is assumed that the glass panel 5 labeled “5a” in FIG. 1A has been damaged, but the glass provided in other parts of the balustrade 3 Needless to say, the temporary balustrade panel 10 having the above-described configuration can be used even when the other glass panel 5 having the same shape as the main surface of the panel 5a is damaged.

  A shape different from the main surface of the glass panel 5a, that is, each of the glass panel 5b having a substantially fan-shaped main surface and the glass panel 5c having a substantially semicircular main surface, What is necessary is just to prepare the other temporary balustrade panel which consists of the structure similar to said temporary balustrade panel 10 corresponding to a shape.

  The temporary balustrade panel 10 corresponding to each of the glass panels 5a, 5b and 5c constituting the balustrade 3 and the other temporary balustrade panels described above have the balustrade 4 located on the opposite side of the balustrade 3 across the travel path of the step 2. Even when a glass panel (not shown) to be constructed is damaged, the glass panel can be used without any problem as long as it has the same shape and thickness as the broken glass panel.

  Therefore, according to the temporary balustrade panel 10 and the other temporary balustrade panels described above, there are cases in which the shapes of the main surfaces are different, such as the existing glass panels 5a, 5b, 5c constituting the balustrade 3. However, at least one set corresponding to each glass panel 5a, 5b, 5c, if necessary, a large number of components having the same shape as those having a large number of components (in this example, the glass panel 5a) are stocked. If it is done, it can be exchanged with any one of the glass panels 5 constituting the balustrade 3, so that it is sufficient to temporarily restore the escalator 1. For this reason, the situation that the stock burden of the regular glass panel used at the time of this restoration increases will not be caused.

  Moreover, as described above, the temporary balustrade panel 10 can have a simple structure that can be obtained at a low cost, so even if it is stocked with some margin in quantity, the same number of glass panels 5 can be used as a supplement. It is not enough to put the stock burden enough to stock.

  Although the temporary balustrade panel 10 and the like according to the embodiment have been described above, the temporary balustrade panel according to the present invention can be implemented in other forms.

  (1) In the above embodiment, the wood plywood 11 which is a kind of wood board is used as the main body panel, but other kinds of wood board may be used. For example, a known wooden board such as a wooden board, a laminated board, a particle board, or a fiber board such as an insulation board, a hard board, or a medium density fiber board (MDF) can be used. These wooden boards may be a single layer or may be a laminate of a plurality of boards.

  (2) The material of the main body panel is not necessarily made of wood, and may be made of, for example, a resin, a paper material, or a composite material obtained by mixing these materials. In particular, if a transparent panel made of a transparent resin such as an acrylic resin with excellent transparency and a polycarbonate resin having both transparency and impact resistance is used for the main body panel, it has the same design as a glass panel. This is advantageous in that it can be held, and the temporary restoration operation can be performed without substantially impairing the beauty of the escalator 1. In this case, for example, a surface treatment such as a polishing treatment such as a buff finish, a hard coat treatment for imparting scratch resistance to maintain a transparent design property, an optical adjustment treatment for adjusting optical characteristics such as total light transmittance, This corresponds to a makeup process on the main surface of the transparent panel.

  (3) In the above-described embodiment, the pair of metal thin plates 12 and 13 that are decorative sheets are provided on both main surfaces of the plywood 11 that is the main body panel as the decorative treatment. Other cosmetic treatments may be applied as long as the strength and rigidity to such an extent that no occurrence occurs can be ensured. For example, it may be subjected to a cosmetic process such as painting, vapor deposition, or pasting a decorative sheet made of other materials (for example, resin, paper, etc.). A surface treatment such as a resin coating may be further applied to both main surfaces of the main body panel subjected to these decorative treatments.

  (4) The makeup process does not necessarily have a metallic tone as long as the makeup process does not impair the beauty. For example, a makeup process may be applied so as to give a design property common to textures and patterns of the wall surface, floor surface, and other surrounding ornaments of buildings. Even in such a makeup process, a sense of discomfort is reduced due to the relationship between the escalator 1 and the surrounding appearance, and the temporary restoration operation can be performed without impairing the aesthetics of the escalator 1 as compared with the prior art.

  (5) The makeup process does not necessarily have to be performed over the entire surface of both main surfaces of the main body panel, and the makeup process may be performed on a part of the entire main surface. Further, different makeup treatments may be applied to one main surface and the other main surface of the main body panel. For example, if the inner main surface close to the step 2 is subjected to a metal-like cosmetic treatment or a decorative cosmetic treatment, and the outer main surface located on the opposite side is subjected to a promotional advertisement as a cosmetic treatment, The panel can also be used as a temporary information medium.

  (6) The balustrade 3 (and balustrade 4) of the escalator 1 described above has the largest number of rectangular glass panels 5a as a common part. For example, glass provided in a region where the moving handrail is skewed. The present invention can also be applied to an escalator having a balustrade whose shape of the main surface of the panel is a parallelogram. In this case, a temporary balustrade panel corresponding to the glass panel having the main surface of the parallelogram may be further prepared.

  (7) In the above embodiment, the escalator 1 used for ascending is described as an example, but the escalator 1 may be used for descending. In this case, each of the steps 2 connected in a circular manner is circulated in the direction opposite to the arrow shown in FIG. 1 (a), and passengers riding on the steps 2 are carried downstairs.

  (8) In the above embodiment, the temporary balustrade panel according to the present invention has been described based on an example in which the temporary balustrade panel according to the present invention is applied to an escalator balustrade. However, the temporary balustrade panel according to the present invention is not limited to an escalator, but other passenger conveyors, For example, the present invention can be applied to a parapet of a “moving sidewalk” of a pallet type or a rubber belt type. That is, the present invention can also be applied to a parapet of a moving sidewalk that circulates and travels an endless transport body composed of a plurality of pallets connected in an annular manner and an endless transport body composed of a rubber belt.

  The present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Moreover, you may implement with the form which substituted any invention specific matter to the other technique within the range which the same effect | action or effect produces.
