Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the technology described in Patent Document 1 above, the specific composition of the adhesive for joining the side plate and the reinforcing material, the combination with the adherend, the coating structure, and the coating method are not described. When assembling the side plate structure with an adhesive, it is important to maintain the strength of the joint over a long period of time. Further, the side plate structure is a part that is visible to people riding in the elevator car, and has a feature that requires designability of the appearance. For this reason, for elevator apparatuses and elevator cars, a side plate structure capable of maintaining the reliability of the adhesive strength over a long period of time, suppressing a decrease in the designability of the side plate due to curing shrinkage strain of the adhesive, and having good productivity is required.

The first fixing member has higher adhesive strength and lower curing shrinkage rate than the second fixing member. The second fixing member has a shorter curing time than the first fixing member.

[0008] The elevator car of the present invention comprises a side plate structure consisting of a surface plate, a reinforcing member, a first fixing member and a second fixing member positioned between the surface plate and the reinforcing member and fixing the surface plate and the reinforcing member by adhesive.

[Modes for carrying out the invention]

[0013] Hereinafter, examples of elevator devices, elevator cars, and elevator side panel structures according to embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following examples. In the figures described below, common components are denoted by the same reference numerals. Furthermore, in the drawings used herein, identical or corresponding components are denoted by the same reference numerals, and repeated descriptions of these components may be omitted.

[0014] [Configuration of Elevator Device] Fig. 1 shows a schematic configuration diagram of an elevator device. The elevator device shown in Fig. 1 is installed in a hoistway (not shown). In the elevator device, one end of the main rope 2 wound around the hoisting machine 1 is suspended after passing through a pair of left and right car lower pulleys 4A and 4B provided at the lower part of the car 3, and is fixed at the upper part position of the hoistway. Also, the other end of the main rope 2 is suspended after passing through the pulley 6 of the counterweight 5, and is fixed at the upper part position of the hoistway. The elevator device rotates and drives the hoisting machine 1, so that the car 3 provided on one side of the main rope and the counterweight provided on the other side of the main rope move up and down in the hoistway.

[0015] [Configuration of Elevator Car] Next, Fig. 2 shows a perspective view of the elevator car 3 of the elevator device. Fig. 2 shows the state of viewing from the landing side to the back side of the car 3. The elevator car 3 includes a floor plate 31, a ceiling plate 32 disposed above the floor plate 31, and a sill 33 installed so as to rise from the floor plate 31. Also, the elevator car 3 includes a plurality of back side side plate structures 100 installed on the sill 33 in the depth direction when viewed from the front of the landing, and side side plate structures 100 installed on the sill 33 in the left and right directions when viewed from the front of the landing. In the car 3 shown in Fig. 2, the back side of the car 3 is composed of a plurality of side plate structures 100, but the side plate structure 100 may be composed of one piece. Also, the side side plate structure 100 is composed of one piece, but the side plate structure 100 may be composed of a plurality of pieces.

[0016] [Configuration of Side Plate Structure] Next, Figs. 3, 4, and 5 show the configuration of the side plate structure 100 used for the elevator car. Fig. 3 is a front view of the side plate structure 100 from the inside of the elevator, Fig. 4 is a cross-sectional view taken along line A-A of the side plate structure 100 shown in Fig. 3. Fig. 5 is an exploded view of the side plate structure 100.

[0017] As shown in FIGS. 3 to 5, the side plate structure 100 of the elevator includes a surface plate 110, a reinforcing member 120, and a fixing member 130 that fixes the surface plate 110 and the reinforcing member 120 by adhesion. The fixing member 130 includes a first fixing member 131 and a second fixing member 132.

[0018] (Surface plate) The surface plate 110 is joined to the reinforcing member 120 via the fixing member 130. That is, the surface plate 110 is joined to the reinforcing member 120 via the first fixing member 131 and the second fixing member 132.

[0019] The end of the surface plate 110 is bent at a right angle toward the outside of the car 3. When the car 3 is composed of a plurality of surface plates 110 on one surface, the adjacent surface plates 110 may be fastened with bolts or the like at the bent portion of the end.

[0020] (Reinforcing member) The reinforcing member 120 is joined and fixed to the back surface side of the surface plate 110, that is, the surface opposite to the inside of the car 3. The reinforcing member 120 does not need to be formed on the entire surface of the surface plate 110, and it may be joined to a part of the surface plate 110. As shown in FIGS. 4 and 5, the reinforcing member 120 has a pair of vertical wall portions 121, a top surface portion 122, and a pair of flange portions 123, and has a so-called hat-shaped cross-sectional shape in which the flange portion 123, the vertical wall portion 121, and the top surface portion 122 are continuously formed. The reinforcing member 120 only needs to have a plane that can be joined to the surface plate 110, and the shape of the reinforcing member 120 is not particularly limited. Examples of the shape of the reinforcing member 120 applicable to the side plate structure 100 will be described later. One surface of the flange portion 123 (the surface opposite to the vertical wall portion 121 and the top surface portion 122) of the reinforcing member 120 is joined to the back surface side of the surface plate 110 via the fixing member 130.

[0021] In Figures 3-5, the reinforcing members 120 are joined so that the longitudinal direction of the surface plate 110 and the longitudinal direction of the reinforcing member 120 are in the same direction, but the orientation in which the reinforcing members 120 are joined to the surface plate 110 is not limited. The reinforcing members 120 may be joined so that the width direction of the surface plate 110 is the longitudinal direction of the reinforcing member 120. Also, in Figures 3-5, one reinforcing member 120 is joined to one surface plate 110, but the number of reinforcing members 120 joined to the surface plate 110 is not limited. In the side plate structure 100, the configuration of the reinforcing members 120 can be applied considering the size of the surface plate 110 and the reinforcing members 120, the required strength, etc.

[0022] (fixing material) The fixing member 130 is formed between the back side of the surface plate 110 and one side of the flange portion 123 of the reinforcing member 120. The fixing member 130 is a member for joining the surface plate 110 and the reinforcing member 120. The surface plate 110 and the reinforcing member 120 may also be joined together with the fixing member 130 by joining members such as bolts. The fixing member 130 consists of a first fixing member 131 and a second fixing member 132. The first fixing member 131 and the second fixing member 132 are each made up of different materials.

[0023] In the fixing member 130, the first fixing member 131 is provided such that the area formed between the surface plate 110 and the reinforcing member 120 is greater than or equal to the area formed by the second fixing member 132. Since the first fixing material 131 has a larger formation area than the second fixing material 132, the first fixing material 131 primarily determines the adhesive properties between the surface plate 110 and the reinforcing material 120. For example, the ratio of the formation area of ​​the first fixing material 131 to the formation area of ​​the second fixing material 132 between the surface plate 110 and the reinforcing material 120 is formed to be approximately "first fixing material:second fixing material = 1:1 to 10000:1". Also, the ratio of the area of ​​the surface plate 110 to the formation area of ​​the fixing material 130 (the total area of ​​the first fixing material 131 and the second fixing material 132) is formed to be, for example, "surface plate:fixing material = 3:2 to 100:1".

[0024] Furthermore, the first fixing material 131 has higher adhesive strength than the second fixing material 132. For example, the adhesive strength of the first fixing material 131 is preferably higher than that of the second fixing material 132, and is 10 MPa or more. Conversely, the adhesive strength of the second fixing material 132 is preferably 1 MPa or more, and lower than that of the first fixing material 131. The adhesive strength between the first fixing material 131 and the second fixing material 132 shall be measured in accordance with JIS K 6850. The adhesive strength shall be defined as the tensile shear strength (the load at which the test piece breaks divided by the adhesive area) obtained by tensile testing of a simply overlapped adhesive test piece. The test piece shall be cured for 120 hours after bonding. The process from bonding to testing shall be carried out at room temperature (20°C).

[0025] The first fixing material 131 is made of a material with a lower curing shrinkage rate than the second fixing material 132. For example, the curing shrinkage rate of the first fixing material 131 is preferably 10% or less, and lower than that of the second fixing material 132. Conversely, the curing shrinkage rate of the second fixing material 132 is preferably higher than that of the first fixing material 131 and 20% or less. The curing shrinkage rates of the first fixing material 131 and the second fixing material 132 are measured by three-dimensional measurement of the volume change before and after curing, using a test specimen made by dropping the adhesive onto a steel plate. The cured state is defined as the state after 120 hours of standing. The procedure from dropping to measurement is carried out at room temperature (20°C).

[0026] The second fixing material 132 is made of a material with a shorter curing time than the first fixing material 131. For example, the curing time of the second fixing material 132 is preferably 3 minutes or less, which is shorter than that of the first fixing material 131. Conversely, the curing time of the first fixing material 131 is preferably longer than that of the second fixing material 132, and is between 3 minutes and 24 hours. The curing time for the first fixing material 131 and the second fixing material 132 is defined as the minimum time at which the tensile shear strength of a simply overlapped test specimen, after a predetermined time has elapsed since bonding, reaches 0.1 MPa or higher when subjected to a tensile test. The procedure from dripping to measurement is carried out at room temperature (20°C).

[0027] By using a fixing material 130 consisting of the first fixing material 131 and the second fixing material 132 as described above, the second fixing material, which has a faster curing rate, functions as a temporary fixing material when joining the surface plate 110 and the reinforcing material 120. In this way, high productivity can be achieved because the curing time of the second fixing material 132 is shorter than that of the first fixing material 131. Furthermore, because the first fixing material 131, which has a large formation area, has a low curing shrinkage rate, the deterioration of the design due to curing shrinkage of the fixing material 130 can be suppressed. In addition, because the first fixing material 131, which has a large formation area, has high adhesive strength, it is possible to ensure that the strength between the surface plate 110 and the reinforcing material 120 is maintained over a long period of time, and the first fixing material 131 functions as the main fixing material. Therefore, by bonding the surface plate 110 and the reinforcing material 120 with the fixing material 130 with the above configuration, it is possible to improve the reliability of adhesive strength, design, and productivity.

[0028] (First fixing material) The first fixing material 131 used as the main fixing material requires long-term strength and durability. For adhesive bonding of structures in such applications, mainly one-component heat-curing adhesives and two-component room-temperature curing adhesives are used. One-component heat-curing adhesives have a single solvent and require heating to cure. Two-component room-temperature curing adhesives have two solvents and can be cured at room temperature by mixing the two components. In the side plate structure 100, from the viewpoint of design, it is desirable to use a two-component room-temperature curing adhesive, which does not require heating and therefore exhibits less curing deformation.

[0029] As a two-component, room-temperature curing structural adhesive, for example, an adhesive containing one or more selected from two-component epoxy adhesives, two-component acrylic adhesives, two-component urethane adhesives, and two-component silicone adhesives can be used. Furthermore, as a two-component, room-temperature curing structural adhesive, it is preferable to use an adhesive containing one or more selected from two-component epoxy adhesives and two-component acrylic adhesives. In particular, it is preferable to use an adhesive containing a two-component acrylic adhesive. Two-component acrylic adhesives have acrylic monomer as their main component and have high compatibility with machine oil and hydraulic oil remaining on the surface of the adherend, thus exhibiting excellent adhesion to oily surfaces. For this reason, two-component acrylic adhesives have good strength stability against residual oil on the adherend, and the strength and reliability of the adhesive structure are excellent.

[0030] Two-part acrylic adhesives harden when two components are mixed: component A, which mainly consists of acrylic monomer and contains organic peroxides as additives, and component B, which mainly consists of acrylic monomer and contains reducing agents as additives. First, as a method for curing the two-part acrylic adhesive, it is conceivable to mix the A and B components of the two-part acrylic adhesive using a mixing nozzle or the like, and then extrude it as the first fixing agent 131. Furthermore, two-part acrylic adhesives have a long reaction period, and high strength can be obtained even without thorough mixing. For this reason, agent A and agent B may be applied in a bead-like manner to at least one of the surface plate 110 and the reinforcing material 120. In this case, when the surface plate 110 and the reinforcing material 120 are pressed together, agent A and agent B mix and harden, forming the first fixing material 131. In this case, the reaction between agent A and agent B is less likely to occur in the applied state, thus extending the working time in the applied state. Alternatively, a honeymoon coating method may be used, where agent A is applied to one of the surface plate 110 and the reinforcing material 120, and agent B is applied to the other. In this case as well, when the surface plate 110 and the reinforcing material 120 are pressed together, agent A and agent B mix and harden, forming the first fixing material 131. In this case, the reaction between agent A and agent B does not occur in the applied state, thus extending the working time in the applied state.

[0031] Two-part acrylic adhesives are predominantly composed of methyl methacrylate as the acrylic monomer. On the other hand, there are two-part acrylic adhesives that are primarily composed of acrylic oligomers with larger molecular weights than methyl methacrylate, such as phenoxyethyl methacrylate and 2-hydroxypropyl methacrylate. Examples of such acrylic oligomers with larger molecular weights than methyl methacrylate include methacrylic acid esters, acrylic acid esters, and their polymers.

[0032] Two-component acrylic adhesives, primarily composed of methacrylate esters or acrylic oligomers with a larger molecular weight than methyl methacrylate, exhibit suppressed curing shrinkage during polymerization due to their larger molecular weight. Therefore, by using a two-component acrylic adhesive primarily composed of methacrylate esters or acrylic oligomers as the first fixing material 131, the aesthetic appearance of the side plate structure 100 is less likely to be impaired by curing shrinkage distortion of the adhesive. Furthermore, two-part acrylic adhesives, primarily composed of methacrylate esters or acrylic oligomers, have fewer of the difficult-to-handle characteristics of methyl methacrylate, such as its high volatility, resulting in an unpleasant odor and a low flash point.

[0033] (Second fastener) The second fixing material 132, used as a temporary fixing material, is a fast-curing adhesive. The second fixing material 132 is preferably an adhesive that cures at room temperature, from the viewpoint of avoiding deformation due to heating. For example, an adhesive containing one or more selected from anaerobic adhesives, cyanoacrylate adhesives (instant adhesives), and photocurable / UV-curable adhesives can be used. In particular, as the second fixing material 132, it is preferable to use an anaerobic adhesive mainly composed of acrylic monomer because it has excellent adhesion to oily surfaces and good strength stability. Anaerobic adhesives containing organic peroxides as polymerization initiators undergo a redox polymerization reaction by radicals supplied from the reaction of metal ions and organic peroxides when oxygen is blocked, and cure. Therefore, by using the above anaerobic adhesive as the second fixing material 132, oxygen is blocked from the anaerobic adhesive by pressing the surface plate 110 and the reinforcing material 120 together, and the anaerobic adhesive cures rapidly.

[0034] Furthermore, as described above, by using the side plate structure 100, which has high strength reliability and aesthetic appeal, it is possible to construct an elevator car and an elevator system equipped with this car that have high reliability and aesthetic appeal.

[0035] Furthermore, the surface plate 110 and the reinforcing material 120 are not only joined by the fixing material 130, but may also be joined using other methods such as screws, bolts, nuts, or welding in addition to the aforementioned fixing material 130. In this case as well, the above-described effects can be obtained by using the first fixing material 131 and the second fixing material 132 as the fixing material 130. Furthermore, by using joining materials or welding, the joint strength between the surface plate 110 and the reinforcing material 120 can be improved, thereby improving reliability.

[0036] [Reinforcement material] Examples of reinforcing member shapes applicable to the side plate structure 100 will be explained using Figures 6-9. Figures 6-9 show the cross-sectional shapes of the reinforcing members. Note that the reinforcing member configurations shown in Figures 6-9 are applicable to the side plate structure 100 configurations shown in Figures 3-5, unless there are special circumstances.

[0037] Figure 6 shows the configuration of a reinforcing member 140 having a groove-shaped cross-section. As shown in Figure 6, the groove-shaped reinforcing member 140 has flange portions 152 that bend at right angles at the bends at both ends of the web 141, and a U-shaped groove is formed in its cross-section. The surface on which the fixing member 130 is formed of the groove-shaped reinforcing member 140 is not particularly limited, but forming the fixing member 130 on the outer surface of the web 141 tends to improve the rigidity of the side plate structure.

[0038] Figure 7 shows the configuration of a reinforcing member 150 having a lip groove cross-sectional shape. As shown in Figure 7, the reinforcing member 150 has flange portions 152 that bend at right angles at the bends at both ends of the web 151, and lip portions 153 that bend inward at right angles at the bends at the tips of the flange portions 152. Therefore, the reinforcing member 150 has a C-shaped cross-section that opens to the side. Compared to the reinforcing member 140 having a groove cross-sectional shape, the lip groove-shaped reinforcing member 150 has superior second moment of area and provides the effect of improved rigidity. Furthermore, although the surface on which the fixing member 130 is formed in the lip groove-shaped reinforcing member 150 is not particularly limited, forming the fixing member 130 on the outer surface of the web 151 tends to improve the rigidity of the side plate structure.

[0039] Figure 8 shows the configuration of the reinforcing member 120 having a hat-shaped cross-section. The reinforcing member 120 has the same configuration as the reinforcing member 120 with the shape shown in Figures 4 and 5 above. Because the reinforcing member 120 with a hat-shaped cross-section is wide, it has the effect of improving the rigidity of the entire surface of the surface plate 110 in the side plate structure 100.

[0040] Figure 9 shows the configuration of a reinforcing member 160 with a corrugated cross-sectional shape. The reinforcing member 160 has a shape in which a concave surface 161 and a convex surface 162 are continuously formed over the entire length direction via a vertical wall portion 163. Furthermore, in the corrugated reinforcing member 160, for example, the vertical wall portion 163 may be an inclined surface, and the length (width) of the concave surface 161 and the convex surface 162 does not have to be the same. The reinforcing member 160 with a corrugated cross-section can be formed wider than other shapes, and the pitch of the highly rigid joints becomes narrower. Therefore, by using the corrugated reinforcing member 160, the rigidity of the entire surface of the surface plate 110 in the side plate structure 100 is improved, and the effect of uniform rigidity of the side plate structure is obtained.

[0041] The cross-sectional shape of the reinforcing material can be a groove-shaped reinforcing material 140, a lip-groove-shaped reinforcing material 150, a hat-shaped reinforcing material 120, a corrugated reinforcing material 160, etc., as described above, but the shape is not limited. In the side plate structure 100, it is sufficient if the shape allows for reinforcement of the surface plate 110 and can be joined by the fixing material 130.

[0042] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are included. For example, the embodiments described above are described in detail to make the present invention easier to understand, and are not necessarily limited to those having all the configurations described. Furthermore, it is possible to replace parts of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add configurations from other embodiments to the configuration of one embodiment. In addition, it is possible to add, delete, or replace parts of the configuration of each embodiment with other configurations. [Explanation of Symbols]
