Description

【Technical Field】 【0001】 The present invention relates to a transfer plate member that is transferred from an elevator to the floor surface of a building body. 【Background Art】 【0002】 Conventionally, a cart is moved in and out of an elevator car to carry luggage and the like. Such carts generally include a cart that is manually moved (hereinafter, may be referred to as a "general cart") and an AGV (Automatic Guided Vehicle: unmanned transport vehicle or unmanned cart). 【0003】 For the entry and exit of carts including general carts and AGVs into the elevator car, a transfer plate is placed between the elevator car and the floor of the building, that is, the floor surface of the building body where the elevator is installed. For example, Patent Document 1 discloses moving a tread plate that transfers the gap between the elevator and the floor surface of the building body by an automatic slide mechanism in an elevator having a door in an opening for loading and unloading luggage and the like at the front. This automatic slide mechanism includes a guide rail provided in the vertical direction along the front of the elevator, a support rod provided via a guide roller along this guide rail, an angle having a length substantially equal to the width of the opening of the elevator provided on this support rod, a cylinder for raising and lowering the tread plate attached to the guide rail and the angle, a hinge for attaching the tread plate provided on this angle, and a cylinder for operating the tread plate provided on the angle for tilting the tread plate. The tread plate is attached to the aforementioned hinge. When the elevator stops at the target floor, the automatic slide mechanism extends the cylinder for raising and lowering the tread plate to raise the tread plate to a position aligned with the floor surface of the building body, and then contracts the cylinder for operating the tread plate to tilt the tread plate and ground it on the floor surface of the building body. This enables loading and unloading by opening the door. 【Prior Art Documents】 【Patent Documents】 【0004】 [Patent Document 1] Patent No. 3151575 [Overview of the Initiative] [Problems that the invention aims to solve] 【0005】 The automatic sliding mechanism described in Patent Document 1 above is operable when a sensor detects that the floor surface of the building structure and the floor surface of the elevator car (hereinafter simply referred to as "floor surface") are aligned, and furthermore, it is necessary to operate two cylinders in a predetermined order in order to bring the treads into contact with the ground. 【0006】 The objective of this invention is to enable the connection between the elevator floor and the building's floor surface with a simpler configuration when the elevator arrives at the target floor. [Means for solving the problem] 【0007】 To achieve the above objective, one aspect of the present invention is: An elevator crossing plate member having an opening that is opened and closed by a downward-opening door member, at least the lower portion of which is open, A first plate member is provided on the inside of the door member so as to be rotatable relative to the door member, A second plate member provided on the tip side of the first plate member, An elastic member provided between the first plate member and the second plate member, A locking member that locks the second plate member to the first plate member and A connecting plate member equipped with To provide. 【0008】 Preferably, the elastic member is a leaf spring. 【0009】 Preferably, the locking member comprises an elastic member. 【0010】 Preferably, a decorative panel is provided on at least one of the surfaces of the first plate member and the second plate member. 【0011】 A third plate member may be further provided on the tip side of the second plate member. [Effects of the Invention] 【0012】 According to one aspect of the present invention, with the above configuration, when the elevator arrives at the destination floor, the door member opens, allowing the connecting plate member to automatically lean onto the floor surface of the building structure due to its own weight, thus connecting the elevator floor and the floor surface of the building structure with a simple configuration. [Brief explanation of the drawing] 【0013】 [Figure 1] This is a plan view of a connecting plate member according to one embodiment of the present invention. [Figure 2] This is an elevation view showing the elevator car opening side on a floor of a building structure, with the elevator car door closed and the elevator car raised, to which the elevator car member shown in Figure 1 is applied. [Figure 3] Figure 1 is an enlarged cross-sectional view of the connection point of the connecting plate member to the elevator. [Figure 4] This is an enlarged schematic cross-sectional view of a part of the connecting plate member shown in Figure 1.

[Figure 6] Figure 2 is a schematic cross-sectional view showing the unfolded bridging plate member in the elevator, illustrating the case where the floor surface of the building structure is approximately aligned with the floor surface of the elevator. [Figure 7] Figure 2 is another schematic cross-sectional view showing the unfolded bridging plate member in the elevator, illustrating the case where the floor surface of the building structure is shifted downwards relative to the elevator floor surface. [Modes for carrying out the invention] 【0014】 Hereinafter, embodiments according to the present invention will be described based on the attached drawings. The same parts (or components) are denoted by the same reference numerals, and their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated. 【0015】 The transfer plate member 10 according to an embodiment will be described based on the drawings. FIG. 1 shows the transfer plate member 10, FIG. 2 shows where the transfer plate member 10 is applied to the elevator 14, FIG. 3 is an enlarged view of the connecting portion of the transfer plate member 10 to the car 12 of the elevator 14, FIG. 4 is an enlarged schematic view of the connecting portion of the plate members 16 and 18 of the transfer plate member 10, FIG. 5 is a cross-sectional view of a part of the elevator along the line V-V in FIG. 2, showing the transfer plate member 10 in the stored state, and FIGS. 6 and 7 are views showing the transfer plate member 10 in the unfolded state. 【0016】 As shown in FIG. 1, the transfer plate member 10 according to an embodiment includes a first plate member 16, a second plate member 18, an elastic member 20, and a locking member 22. Here, one transfer plate member 10 is used as the transfer plate in one elevator 14, but two or more transfer plate members 10 may be connected and used as the transfer plate for one elevator 14, that is, one car 12. For example, as the transfer plate of one elevator, four transfer plate members 10 may be connected and used in the width direction. This transfer plate member 10 is applied to an elevator having a car whose at least the lower part has an opening opened and closed by a downward-opening door member. Here, the elevator 14 to which the transfer plate member 10 is applied includes an inner door 28, which is an up-and-down opening door member, in its opening 24. 【0017】 FIG. 2 shows a view of the opening 24 side of the car 12 of the elevator 14 as seen from the outside of the elevator 14, i.e., from a floor with a building structure, and the opening 24 is closed by an outer door 26 and an inner door 28. In FIG. 2, at a certain floor, the car 12 stops at a position where passengers can get on and off. An inner door 28 for opening and closing the opening 24 is provided at the opening 24 of the car 12 of the elevator 14. The inner door 28 supported by the car 12 is located inside the outer door 26 provided at the opening of each floor of the building structure. The outer door 26 and the inner door 28 are configured to be interlocked and each has a configuration of opening vertically upward and downward. The doors 26 and 28 are configured to be automatically opened by a driving device 29 having a driving motor when the elevator 14 arrives at the target floor of the building structure and to be automatically closed when moving to another target floor. Note that the outer door 26 and / or the inner door 28 may be manually opened and closed. In FIG. 2, when the doors 26 and 28 are opened, the upper portions 26u and 28u open upward (arrow A1), and the lower portions 26d and 28d open downward (arrow A2). When closing from the open state, the upper portions 26u and 28u move downward (arrow A1), and the lower portions 26d and 28d move upward (arrow A2). Thus, as shown in FIG. 2, the upper portions 26u and 28u and the lower portions 26d and 28d cooperate to close the opening 24. The inner door 28, i.e., its lower portion 28d, corresponds to the door member of the present disclosure and opens and closes at least the lower portion of the opening 24 opened and closed by the door member. 【0018】 As shown in FIG. 2, when the opening 24 is closed, the transfer plate member 10 stands and extends generally vertically in the up-and-down (vertical) direction. At this time, as shown in FIG. 5, the transfer plate member 10 leans on the inner door 28, places its weight on the inner door 28, and is supported by the inner door 28. 【0019】 The first plate member 16 of the connecting plate member 10 is rotatably mounted on the inside of the inner door 28 (i.e., the inside of the cage 12) relative to the inner door 28, and particularly relative to its lower portion 28d (see, for example, Figures 3, 5, 6, and 7). The first plate member 16 is plate-shaped and is configured to rotate within a predetermined range around its base end 30. A pivot shaft 31 is provided at the base end 30. Note that the pivot shaft 31 is an example of a pivoting member and may be a hinge. 【0020】 Here, refer to Figure 3, which is an enlarged view of the attachment point of the connecting plate member 10 to the car 12. The pivot shaft 31 is positioned at the outer lower end of the opening 24 of the elevator 14, that is, at the end face portion 12e on the opening 24 side of the floor wall 12f to which the floor surface 14s of the elevator car 12 of the elevator 14 extends. At this time, a limiting member L is provided to restrict the rotation of the pivot shaft 31 about its axis 31A to a predetermined range. Here, the predetermined range is approximately 90°, and the limiting member L is an L-shaped member. As a result, the first plate member 16 can take on states including a state that is substantially parallel to the floor surface 14s shown by a solid line in Figure 3, a state that extends substantially perpendicular to the floor surface 14s shown by a dashed line in Figure 3, and states in between these two. 【0021】 The second plate member 18 is provided on the tip 32 side of the first plate member 16. The second plate member 18 is a plate-shaped member and is formed to become thinner from the base end 34 side to the tip 36 side on the first plate member 16 side. As shown in Figure 4, the base end 34 of the second plate member 18 has a shape that matches the shape of the tip 32 of the first plate member 16. The tip 32 of the first plate member 16 is shaped to have an arc-shaped cross section, and the base end 34 of the second plate member 16 has a concave, curved arc shape into which the tip 32 of the first plate member 16 fits. However, the shapes of these ends 32 and 34 are not limited to this and may have other shapes. 【0022】 As shown in Figure 1, the connecting plate member 10 has multiple shaft portions 15 extending in the vertical direction D1. Each shaft portion 15 has a main shaft portion 15a and a secondary shaft portion 15b. In the connecting plate member 10, the main shaft portions 15a are provided on both sides and in the center, and six secondary shaft portions 15b are provided between the main shaft portions 15a. These shaft portions 15 (15a, 15b) are mainly provided on the first plate member 16 and extend to the base end 34 of the second plate member 18, and elastic members 20 and locking members 22 are provided between these shaft portions 15a and 15b in roughly alternating positions. Note that the main shaft portion 15a and the secondary shaft portion 15b are each divided at the point between the first plate member 16 and the second plate member 18, and consist of two members. In other words, the main shaft portion 15a comprises members 15aa and 15ab, and the sub-shaft portion 15b comprises members 15ba and 15bb. These shaft portions 15 (15a, 15b) are provided and arranged to increase the rigidity of the transfer plate member 10 to a predetermined level or higher. Therefore, the number, dimensions, and types of shaft portions 15 should be designed according to the weight of a trolley such as an AGV that is expected to travel on the transfer plate member 10. 【0023】 The second plate member 18 is constructed by connecting multiple plate-shaped members 19 in the vertical direction D1, which extend in the width direction D2 perpendicular to the vertical direction D1. As described above, the second plate member 18 is formed to become thinner from the base end 34 on the first plate member 16 side to the tip end 36 side, and thinner plate-shaped members 19 are used towards the tip end 36 side. These plate-shaped members 19 are connected by rivets 19a. The connecting plate member 10 is installed on the elevator 14 such that the width direction D2 is parallel to the left-right direction of the elevator 14 or to the width direction D3 (a direction perpendicular to the vertical directions A1 and A2). 【0024】 The elastic member 20 is provided between the first plate member 16 and the second plate member 18. Here, as shown in Figure 1, the elastic member 20 is provided between predetermined adjacent sub-shaft portions 15b. The elastic member 20 is a leaf spring 20s. One end of the elastic member 20 is attached to the tip 32 of the first plate member 16, and the other end of the elastic member 20 is positioned at the base end 34 of the second plate member 18. Specifically, one end of the elastic member 20 is inserted into a slit that opens towards the tip 32 side of the tip 32 of the first plate member 16, and the other end of the elastic member 20 is inserted into a slit that opens towards the base end 34 side of the base end 34 of the second plate member 18 (see Figures 4 to 7). Note that in Figure 1, these slits are omitted, and the leaf spring 20s is represented. The leaf spring 20s is fixed to the first plate member 16 with rivets 20a, but is not fixed to the second plate member 18 and is freely movable. The leaf spring 20s is a curved leaf spring and is provided between the first plate member 16 and the second plate member 18 in a direction that is convex downwards when the connecting plate member 10 is placed on the floor surface Fs of the target floor of the building structure (see, for example, Figures 6 and 7). Here, six leaf springs 20s are used for one connecting plate member 10, but this does not limit the number and / or size of the leaf springs. It is preferable to use at least one leaf spring for one connecting plate member 10. Note that the elastic member 20 is not limited to a leaf spring. 【0025】 The locking members 22 are provided to lock the second plate member 18 to the first plate member 16. Two locking members 22 are provided between the main shaft portion 15a and the adjacent sub-shaft portion 15b, and between predetermined adjacent sub-shaft portions 15b, but this is not limited to this arrangement; for example, one locking member may be provided in each position. In this case, the locking members 22 are provided so that two locking members 22 extend between the leaf springs 20s. The installation location 22a of the locking member 22 on the first plate member 16 has no plate-like portion and is open in the thickness direction. The locking member 22 includes an elastic member 38. More specifically, the locking member 22 includes a wire 40 connecting the first plate member 16 and the second plate member 18, and a spring member is provided as the elastic member 38 near one end of the wire. The elastic member 38 may also be provided in the middle of the wire 40. The arrangement and number of locking members 22 are not limited to this. 【0026】 As shown in Figures 3 and 4, decorative panels 42 and 44 are provided on the surfaces of the first plate member 16 and the second plate member 18, which are connected by a locking member 22 and are provided with an elastic member 20. Decorative panel 42 is fixed to the first plate member 16 by fastening means such as rivets, and decorative panel 44 is fixed to the second plate member 18 by fastening means such as rivets. By providing decorative panels 42 and 44, as shown in Figure 3, it becomes easy to extend the surface of the connecting plate member 10 to substantially the same height as the floor surface 14s of the elevator 14. Furthermore, by providing decorative panels 42 and 44, the surfaces of the first plate member 16 and the second plate member 18 become smoother, enabling smoother running of trolleys such as AGVs. Decorative panels 42 and 44 may be provided on only one of the first plate member 16 and the second plate member 18, for example, only on the first plate member 16. In Figure 4, decorative panels 42 and 44 are shown spaced apart for ease of understanding, but the narrower the gap between them, the better. 【0027】 Figure 3 shows the extended bridging plate member 10 extending over the floor surface Fs of the target floor of the building structure, and the upper end of the lower portion 28d of the inner door 28 in the open state. As the lower portion 28d of the inner door 28 rises along the vertical arrow A2, the lower portion 28d of the inner door 28 acts directly on the first plate member 16, thereby allowing the bridging plate member 10 to stand upright as shown in Figures 2 and 5. Therefore, the first plate member 16 should have a strength of a certain strength or greater, and in this case it is made of steel. In contrast, the second plate member 18 is provided on the tip 32 side of the first plate member 16 and moves significantly around the pivot axis 31. Therefore, the second plate member 18 is made of Mg alloy in this case for the purpose of weight reduction. Note that the first plate member 16 may be made of various materials such as metal materials other than steel, and the second plate member 18 may also be made of various materials such as metal materials other than Mg alloy. 【0028】 Furthermore, as shown in Figures 6 and 7, when the connecting plate member 10 is placed over the floor surface Fs of the target floor of the building structure, the tip 32 of the first plate member 16 should directly reach the floor surface Fs. This allows the gap G between the elevator car 12 of the elevator 14 and the floor surface Fs of the target floor to be reliably covered by the first plate member 16, which has higher strength. However, this does not exclude the possibility that the tip 32 of the first plate member 16 may not reach the floor surface Fs. 【0029】 AGVs generally have sensors with a narrow field of view and operate autonomously. In order for the AGV to be able to travel on the transfer plate member 10 using its sensors, the thickness of the first plate member 16, the thickness of the second plate member 18, etc., are designed so that the transfer plate member 10 maintains a suitable inclination (slope) of up to 30 mm / 1000 mm (a slope of 3 cm per meter) when in use as shown in Figures 6 and 7. 【0030】 The movement of the connecting plate member 10 having the above configuration will be explained with reference to Figures 2, 5, 6, and 7. Note that the outer door 26 is omitted in Figures 5, 6, and 7. 【0031】 In elevator 14, when the inner door 28 is closed, as shown in Figures 2 and 5, the bridging plate member 10 is in an upright position leaning against the inner door 28, particularly its lower portion 28d. In this state, when elevator 14 arrives at the destination floor and the outer door 26 opens and the inner door 28 opens, the lower portion 28d moves downward (see arrow A2), and the bridging plate member 10 rotates by its own weight around the pivot axis 31 of the base end 30 of the first plate member 16, allowing it to reach the floor surface Fs of the destination floor. 【0032】 The bridging plate member 10 consists of a first plate member 16 and a second plate member 18 connected by a leaf spring 20s and a locking member 22, and the joint can bend flexibly. Therefore, as shown in Figure 6, the bridging plate member 10 can reach the floor surface Fs and smoothly connect the floor surface 14s of the elevator 14 and the floor surface Fs, not only when the floor surface Fs is at a suitable height relative to the floor surface 14s of the elevator 14, i.e., at approximately the same height, but also as shown in Figure 7, even if the floor surface Fs of the destination floor is significantly lower than the floor surface 14s of the elevator 14. Therefore, a trolley such as an AGV traveling on the floor surface Fs of the destination floor can easily enter the elevator 14, and a trolley inside the elevator 14 can easily move to the floor surface Fs of the destination floor. Furthermore, this connection between the floor surfaces 14s and Fs by the bridging plate member 10 can be established even if the floor surface Fs of the destination floor is shifted upward above the floor surface 14s of the elevator 14. 【0033】 Then, when the opening 24 of the elevator 14, that is, the inner door 28 and the outer door 26, are closed, the lower portion 28d of the inner door 28 rises, causing the first plate member 16 to move in the vertical direction (upwards in the vertical direction) on the pivot axis 31, and the connecting plate member 10 is housed inside the inner door 28. As a result, the connecting plate member 10 is in the state shown in Figures 2 and 5. 【0034】 As described above, the connecting plate member 10 has a simple structure and is operated with a simple structure, and can be converted between the stowed state shown in Figures 2 and 5 and the deployed state (usage state) shown in Figures 6 and 7 as the inner door 28 is opened and closed. Therefore, with the connecting plate member 10, when the elevator arrives at the destination floor, the inner door 28 opens, allowing the connecting plate member 10 to automatically lean onto the floor surface Fs of the building structure by its own weight, thereby enabling a suitable connection between the elevator floor and the floor surface of the destination floor of the building structure. In particular, at that time, the relative relationship between the first plate member 16 and the second plate member 18 can be flexibly changed by the leaf spring 20s and the locking member 22, so that the step between the connecting plate member 10 and the floor surface of the building structure can be made smaller, and thus the trolley can travel more smoothly between the elevator floor and the floor surface of the destination floor of the building structure. 【0035】 In the elevator 14 described above, an inner door 28 was provided in advance. However, if the elevator to which the transponder member of this disclosure is applied does not have a downward-opening door member such as the lower portion 28d of the inner door 28, it is preferable that the inner door 28 be provided together with the transponder member 10. 【0036】 In the transponder member 10, a second plate member 18 is provided on the tip 30 side of the first plate member 16, but a further plate member (third plate member) may be provided on the tip side of the second plate member. In this case, the connection between the second plate member and the third plate member should be made using an elastic member 20 and a locking member 22, similar to the connection between the first plate member and the second plate member. 【0037】 Although embodiments and modifications thereof according to the present invention have been described above, the present invention is not limited thereto. Various substitutions and modifications are possible as long as they do not depart from the spirit and scope of the invention as defined by the claims of this application.
