The first and second support frames 5a and 5b extend along a second lateral direction D2 orthogonal to the first lateral direction D1, and the third and fourth support frames 5c and 5d extend from the first support frame 5a. It extends along the first lateral direction D1 to the second support frame 5b.

  The third and fourth support frames 5c and 5d are connected to the first and second support frames 5a and 5b, respectively. Thereby, the support part 5 is formed in the rectangular shape. In addition, the support part 5 is not restricted to such a structure, For example, the structure which is not provided with the 3rd and 4th support frames 5c and 5d but is provided with only the 1st and 2nd support frames 5a and 5b. But you can.

  Moreover, the support part 5 will not be specifically limited if it has rigidity, For example, it is formed with the metal. For example, the first to fourth support frames 5a to 5d may each be made of a long steel material.

  The floor frame portion 9 includes first and second floor frames 9a and 9b extending so as to be parallel to each other, and third and fourth floor frames 9c and 9d extending so as to be parallel to each other. The first and second floor frames 9a and 9b extend along the second lateral direction D2, and the third and fourth floor frames 9c and 9d extend from the first floor frame 9a to the second floor frame 9b. It extends along one lateral direction D1.

  The third and fourth floor frames 9c and 9d are connected to the first and second floor frames 9a and 9b, respectively. Thereby, the floor frame part 9 is formed in the rectangular shape. The first floor frame 9a faces the first support frame 5a in the vertical direction D3, and the second floor frame 9b faces the second support frame 5b in the vertical direction D3. The floor frame 9c faces the third support frame 5c in the vertical direction D3, and the fourth floor frame 9d faces the fourth support frame 5d in the vertical direction D3.

  In addition, the floor frame portion 9 includes a plurality of reinforcing members 9e disposed between the first and second floor frames 9a and 9b. The plurality of reinforcing members 9e extend along the second lateral direction D2. The plurality of reinforcing members 9e extend from the third floor frame 9c to the fourth floor frame 9d and are connected to the third and fourth floor frames 9c and 9d, respectively. Thereby, since the reinforcing material 9e reinforces the floor frame portion 9, the strength of the floor frame portion 9 is increased.

  The floor frame portion 9 is not particularly limited as long as it has rigidity, but is made of metal, for example. For example, the first to fourth floor frames 9a to 9d and the reinforcing material 9e may each be made of a long steel material. Further, the number of the reinforcing members 9e is not particularly limited.

  The elastic portions 6 a and 6 b include a plurality of first elastic portions 6 a that connect the first floor frame 9 a and the support portion 5, and a plurality of second elastic portions 6 b that connect the second floor frame 9 b and the support portion 5. It has. The first elastic part 6a connects the first floor frame 9a and the first support frame 5a, and the second elastic part 6b connects the second floor frame 9b and the second support frame 5b.

  The elastic portions 6a and 6b are elastically deformed so as to contract in the vertical direction D3 when a downward load is applied to the floor portion 4. Further, when the car frame 3 and the support 5 are swayed, the elastic parts 6a and 6b are elastically deformed in the lateral directions D1 and D2, thereby suppressing transmission of the sway to the floor part 4. The elastic portions 6a and 6b are not particularly limited as long as they have elasticity, but are formed of rubber, for example. For example, the elastic portions 6a and 6b may be vibration-proof rubber.

  The long portion 7 is disposed between the third and fourth floor frames 9c and 9d. The long portion 7 is disposed at the center of the long portion 7, the first connecting portion 7 a connected to the first floor frame 9 a, the second connecting portion 7 b connected to the second floor frame 9 b, and the long portion 7.

The upper surfaces of the first and second connection portions 7a and 7b are each formed in a planar shape, and the lower surfaces of the first and second floor frames 9a and 9b are formed in a planar shape.

  Thus, the elongate part 7 is extended from the 1st floor frame 9a to the 2nd floor frame 9b, and is connected to the 1st and 2nd floor frames 9a and 9b, respectively. Specifically, the long portion 7 extends along the first lateral direction D1, and is connected to the lower portions of the first and second floor frames 9a and 9b, respectively.

  Thereby, the direction D1 in which the elongated portion 7 extends intersects the direction D2 in which the reinforcing material 9e extends in the longitudinal direction D3. Specifically, the direction D1 in which the long portion 7 extends is orthogonal to the direction D2 in which the reinforcing member 9e extends in the longitudinal direction D3. Further, the long portion 7 is separated from all the reinforcing members 9e in the vertical direction D3. In addition, if the elongate part 7 has rigidity, it will not be specifically limited, For example, it is formed with the metal. For example, the long portion 7 may be made of a long steel material.

  The detection unit 8 detects the center position of the long portion 7 between the first connection portion 7a and the second connection portion 7b. The detection unit 8 is fixed to the support unit 5. For example, the detection unit 8 may be directly fixed to the support unit 5 or may be fixed to the support unit 5 with another member interposed. In the present embodiment, the detection unit 8 is fixed to the support unit 5 by being fixed to the lower frame 3 b (not shown in FIGS. 3 and 4) of the car frame unit 3. .

  When a load is applied to the floor portion 4, the elastic portions 6a and 6b are elastically deformed so as to contract in the vertical direction D3, so that the long portion 7 approaches the support portion 5 in the vertical direction D3. Displace to And the detection part 8 detects the load with respect to the floor part 4 based on the displacement amount of the elongate part 7 with respect to the support part 5. FIG. The detection unit 8 is not particularly limited. For example, the detection unit 8 may be a load cell that can detect a load linearly, or may be a touch sensor or a proximity sensor that can detect a load exceeding a predetermined value. But you can.

  By the way, the elastic portions 6a and 6b are arranged so as not to interfere with other components. For example, as shown in FIGS. 5 and 6, the distances between the plurality of elastic portions 6a and 6b are different. 5 and 9 (the same applies to FIGS. 7 to 16), only the floor frame portion 9 is illustrated in the floor portion 4, the floor plate portion 4a is not illustrated, and the support portion 5 is illustrated. Is not shown.

  For example, in FIG. 5, the distance between the left first elastic part 6a and the central first elastic part 6a is greater than the distance between the right first elastic part 6a and the central first elastic part 6a. It is getting bigger. Further, for example, in FIG. 6, the distance between the second elastic part 6b on the right side and the second elastic part 6b on the right side is the distance between the second elastic part 6b on the left side and the second elastic part 6b on the left side. Is also getting bigger. The plurality of elastic portions 6a, 6b all have the same configuration (for example, shape, elastic force).

  And as shown in FIG. 5, the part to which the elongate part 7 is connected to the 1st floor frame 9a, ie, the 1st connection part 7a, is the some 1st elastic part 6a with respect to the edge part of the 1st floor frame 9a. The average position (hereinafter, also referred to as “first position”) P <b> 1 is included. Here, the first connection portion 7a including the first position P1 means that the first connection portion 7a overlaps the first position P1 in the vertical direction D3.

And the distance L1 of the 1st position P1 with respect to the edge part of the 1st floor frame 9a, and distance L1a-L1n of the center position of each 1st elastic part 6a with respect to the edge part of the 1st floor frame 9a are as follows. It becomes a relational expression.
L1 = (L1a + L1b +... + L1n) / n
In the present embodiment, since three first elastic portions 6a are provided, the following relational expression is obtained.
L1 = (L1a + L1b + L1c) / 3

  Further, as shown in FIG. 6, the portion where the long portion 7 is connected to the second floor frame 9b, that is, the second connection portion 7b is a plurality of second elastic portions 6b with respect to the end of the second floor frame 9b. The average position (hereinafter also referred to as “second position”) P <b> 2 is included. Here, the second connection portion 7b including the second position P2 means that the second connection portion 7b overlaps the second position P2 in the vertical direction D3.

And the distance L2 of the 2nd position P2 with respect to the edge part of the 2nd floor frame 9b, and distance L2a-L2n of the center position of each 2nd elastic part 6b with respect to the edge part of the 2nd floor frame 9b are as follows. It becomes a relational expression.
L2 = (L2a + L2b +... + L2n) / n
In the present embodiment, since three second elastic portions 6b are provided, the following relational expression is obtained.
L2 = (L2a + L2b + L2c) / 3

  Therefore, as shown in FIG. 7, the first connection portion 7a of the long portion 7 includes the first position P1, and the second connection portion 7b of the long portion 7 includes the second position P2. The detected part 7c arranged in the center part of the part 7 includes the center position P3 between the first position P1 and the second position P2. The distance L3a between the center position P3 and the first position P1 is the same as the distance L3b between the center position P3 and the second position P2.

  Here, that the detected part 7c includes the center position P3 means that the detected part 7c overlaps the center position P3 in the vertical direction D3. In the present embodiment, the arrangement of the plurality of second elastic portions 6b is line symmetric with the arrangement of the plurality of first elastic portions 6a with respect to the second lateral direction D2.

  The operational effects of such a configuration will be described with reference to FIGS. Moreover, FIGS. 8-10 is illustrated so that the displacement of the floor part 4 and the elongate part 7, and the deformation | transformation of the elastic part 6a may become larger than actual.

  For example, as shown in FIG. 8, when a load is applied in the vicinity of the first connecting portion 7a in the first lateral direction D1, the amount of elastic deformation of each elastic portion 6a is substantially the same. Thereby, the displacement amount S1a of the position of the first connecting portion 7a in the floor portion 4 is the displacement amount S2a on the near side (left side in FIGS. 8 to 10) and the rear side (right side in FIGS. 8 to 10). It is substantially the same as the displacement amount S3a (S1a≈S2a≈S3a). In FIG. 8 (the same applies to FIGS. 9 and 10), the two-dot chain line indicates the lower surface of the floor frame portion 9 (first floor frame 9a) when no load is applied to the floor portion 4. .

  Next, as shown in FIG. 9, a load is applied to the front side of the first connecting portion 7a in the first lateral direction D1 (the same position as FIG. 8 in the first lateral direction D1). In this case, the amount of elastic deformation increases as the elastic portion 6a on the near side increases. Thereby, the displacement amount S1b at the position of the first connecting portion 7a in the floor portion 4 is smaller than the near-side displacement amount S2b and larger than the far-side displacement amount S3b (S2b> S1b> S3b).

  At this time, the floor frame portion 9 (first floor frame 9a) is inclined with the first connection portion 7a (first position P1) as a base point. Therefore, when a load is applied in the vicinity of the first connection portion 7a, the displacement S1a of the position of the first connection portion 7a is the same as that when the same load is applied to the near side of the first connection portion 7a. The displacement amount S1b of the position of the first connecting portion 7a is substantially the same (S1a≈S1b).

  Next, as shown in FIG. 10, when viewed in the first lateral direction D <b> 1, a load is applied to the back side of the first connecting portion 7 a (the same position as in FIGS. 8 and 9 in the first lateral direction D <b> 1). When added, the elastic deformation 6a increases as the elastic part 6a on the back side increases. Thereby, the displacement amount S1c at the position of the first connecting portion 7a in the floor portion 4 is larger than the displacement amount S2c on the near side and smaller than the displacement amount S3c on the back side (S3c> S1c> S2c).

  At this time, the floor frame portion 9 (first floor frame 9a) is inclined with the first connection portion 7a (first position P1) as a base point. Therefore, when a load is applied in the vicinity of the first connection portion 7a, the displacement amount S1a of the position of the first connection portion 7a is the same as when the same load is applied to the back side of the first connection portion 7a. The displacement amount S1c at the position of the first connecting portion 7a is substantially the same (S1a≈S1c). Thus, regardless of the position where the load is applied to the floor portion 4, the displacement amounts S1a to S1c of the position of the first connecting portion 7a are substantially the same (S1a≈S1b≈S1c).

  Since such an operation similarly occurs on the second connecting portion 7b side, even when a load is applied to different positions in the first and second lateral directions D1 and D2, the position of the detected portion 7c including the central position P3 is detected. The displacement amounts of are substantially the same. Thereby, the load value detected by the detection unit 8 is substantially the same regardless of the position where the load is applied to the floor 4. Therefore, the load on the floor portion 4 can be detected accurately.

  In the present embodiment, the first and second elastic portions 6a and 6b are each provided with three, but a plurality of the first and second elastic portions 6a and 6b are provided. If it is, it will not be specifically limited. In addition, in order that the 1st and 2nd elastic parts 6a and 6b may detect the load with respect to the floor part 4 correctly, the structure that each is provided with three or more is preferable.

  Moreover, as shown in FIG.11 and FIG.12, the cage apparatus 2 is provided with the 1st connection mechanism 10 which connects the 1st connection part 7a of the elongate part 7 to the 1st floor frame 9a. Although not shown, the car device 2 includes a second connection mechanism that connects the second connection portion 7b of the long portion 7 to the second floor frame 9b.

And the 1st connection part 7a is connected so that it can slide to the 1st horizontal direction (direction where the elongate part 7 is extended) D1 with respect to the 1st floor frame 9a, and the 2nd connection part 7b. Is connected to the second floor frame 9b so as to be slidable in the first lateral direction D1. In addition, the connection structure of the 2nd connection part 7b and the 2nd floor frame 9b is a structure substantially the same as the connection structure of the 1st connection part 7a and the 1st floor frame 9a, The description is not repeated.

  In the present embodiment, the first connection mechanism 10 includes a bolt 10a and a nut 10b. And the 1st floor frame 9a and the 1st connection part 7a are provided with the hole parts 9f and 7d penetrated by the volt | bolt 10a, respectively. And the hole 7d of the 1st connection part 7a is formed in the elongate hole shape extended in the 1st horizontal direction (direction where the elongate part 7 is extended) D1.

  Thereby, since the 1st connection part 7a can move with respect to the volt | bolt 10a, the 1st connection part 7a can slide to the 1st horizontal direction D1 with respect to the 1st floor frame 9a. The connection structure between the connection portions 7a and 7b and the floor frames 9a and 9b is not limited to such a configuration, and the connection portions 7a and 7b can slide in the first lateral direction D1 with respect to the floor frames 9a and 9b. If it connects so that it may become, it will not specifically limit.

  The operational effects of such a configuration will be described with reference to FIGS. 13 to 15 are illustrated so that the deformation of the floor 4 is larger than the actual deformation.

  As shown in FIGS. 13 to 15, when a load is applied to the floor portion 4, the floor frame portion 9 may be elastically deformed so as to bend (bend). 13 to 15, the alternate long and short dash line indicates the position of the upper surface of the floor frame portion 9 when no load is applied to the floor portion 4, and the alternate long and two short dashes line indicates that the load is applied to the floor portion 4. The position of the upper surface of the floor frame portion 9 when the floor frame portion 9 is not elastically deformed is shown.

  At this time, the displacement amount S4 at the center portion of the floor frame portion 9 in the first lateral direction D1 is larger than the displacement amount S5 at the end portion of the floor frame portion 9 in the first lateral direction D1. That is, the displacement amount S4 at the center includes the displacement amount due to elastic deformation of the floor frame portion 9 in the displacement amount (displacement amount at the end) S5 due to the load.

  Then, as shown in FIG. 13, when the floor frames 9a and 9b are displaced so as to approach each other (in the direction of the arrow in FIG. 13) as the floor frame 9 is elastically deformed, the connecting portion 7a of the long portion 7 is connected. , 7b are fixed to the floor frames 9a, 9b so that the connecting portions 7a, 7b of the long portion 7 are also displaced so as to approach each other (in the arrow direction in FIG. 13). Thereby, the long portion 7 is also elastically deformed so as to be curved. Therefore, when the floor frame portion 9 is elastically deformed so as to be curved, the detection unit 8 erroneously detects the displacement amount S4 including the displacement amount due to the elastic deformation as the displacement amount due to the load.

  Moreover, as shown in FIG. 14, when the elongate part 7 is arrange | positioned in parallel with the reinforcing material 9e, the elongate part 7 does not elastically deform. However, since the third and fourth floor frames 9c, 9d (only the fourth floor frame 9d is shown in FIG. 14) are elastically deformed so as to be curved, the third and fourth floor frames 9c, The displacement amount of the long portion 7 fixed to 9d is the displacement amount S4 including the displacement amount due to the elastic deformation of the floor frame portion 9. Accordingly, when the floor frame portion 9 is elastically deformed so as to be curved, the detection unit 8 erroneously detects the displacement amount S4 including the displacement amount due to the elastic deformation as the displacement amount due to the load.

  On the other hand, as shown in FIG. 15, in the car apparatus 2 according to the present embodiment, the long portion 7 is disposed so as to intersect the reinforcing material 9e, and the connecting portions 7a and 7b are provided on the floor frame. 9a, 9b is slidable in the first lateral direction D1, and the long portion 7 is separated from the reinforcing material 9e. Therefore, when the floor frame portion 9 is elastically deformed so as to be curved, the connecting portions 7a and 7b slide relative to the floor frames 9a and 9b, and the long portion 7 does not contact the reinforcing material 9e. Therefore, the long portion 7 is not elastically deformed.

  Thereby, the displacement amount of the long portion 7 does not include the displacement amount due to the elastic deformation of the floor frame portion 9. That is, the displacement amount of the long portion 7 is the displacement amount S5 due to the load alone. Therefore, even if the floor frame portion 9 is elastically deformed so as to be curved, the load on the floor portion 4 can be accurately detected. The car device 2 preferably has the configuration shown in FIG. 15, but is not limited to such a configuration. For example, the car device 2 may have the configuration shown in FIG. 13 or the configuration shown in FIG. 14. May be.

  As described above, the elevator 1 according to the present embodiment includes the elevator car device 2, the rope 1a connected to the elevator car device 2, and the counterweight 1b connected to the rope 1a.
