[0003] [Patent Document 1] Patent Publication No. 2021-17372 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to check the earthquake resistance performance of an elevator, it is necessary to inspect the spacing of anchor bolts (e.g., the anchor bolt pitch, which is the spacing between the centers of a pair of anchor bolts). In the past, an inspection worker stood on the ceiling of the car and directly contacted the anchor bolts with a convex rule to measure the spacing of the anchor bolts. However, since the distance from the car to the anchor bolts was large, it was difficult and dangerous for the inspection worker to accurately measure the spacing of the anchor bolts. The present disclosure has been made in view of the above problems, and its purpose is to provide an anchor bolt spacing measuring device that can measure the spacing of anchor bolts more safely, more accurately, and more easily. [Means for solving the problem]

[0005] The anchor bolt spacing measuring device of the present disclosure includes a main body, a support member, a convex rule, a tape feeding mechanism, and an operating unit. The main body includes a rod member and a gripping unit. The rod member includes a first end and a second end opposite the first end. The gripping unit is provided at the second end of the rod member. The support member is attached to the first end. The convex rule includes a convex tape and a case. The case is capable of housing the convex tape and is placed on the support member. The tape feeding mechanism can feed the convex tape. The operating unit is provided at the second end of the rod member. The tape feeding mechanism can be operated by the operating unit. Effect of the Invention

[0008] The anchor bolt interval measuring device 30 of the embodiment shown in Figures 6 to 12 is a device for measuring the interval of anchor bolts 21, such as anchor bolts for fixing elevator guide rails. With reference to Figures 1 to 5, the anchor bolts 21 are used to fix brackets 20, 25 supporting guide rails 16, 17 to side walls 3b, 3c, 3d of the hoistway 2.

[0009] 1 and 2, a building 1 is provided with an elevator hoistway 2, a plurality of landings including a lowest floor landing 6 and a highest floor landing 7, a machine room 8, guide rails 16, 17, and an intermediate beam 18. The hoistway 2 has side walls 3a, 3b, 3c, and 3d. The plurality of landings are provided, for example, on the side wall 3a. The side wall 3b faces the side wall 3a. The side wall 3c is connected to the side walls 3a and 3b. The side wall 3d is connected to the side walls 3a and 3b, and faces the side wall 3c. The intermediate beam 18 is fixed, for example, to the side walls 3a and 3b.

[0010] The machine room 8 is provided above the hoistway 2. A hoisting machine 13 and a deflector 14 are arranged in the machine room 8. One end of a wire rope 12 is connected to a car 10. The other end of the wire rope 12 is connected to a counterweight 11. The wire rope 12 moves as the hoisting machine 13 rotates. The car 10 moves up and down the hoistway 2. The counterweight 11 moves up and down the hoistway 2 in the opposite direction to the car 10.

[0011] Guide rail 16 is a guide rail for car 10 and guides car 10. Car 10 moves within hoistway 2 along guide rail 16. Guide rail 17 is a guide rail for counterweight 11 and guides counterweight 11. Counterweight 11 moves within hoistway 2 along guide rail 17.

[0012] 2 to 5, the guide rails 16, 17 are fixed to at least one of the side walls 3b, 3c, 3d of the hoistway 2 using brackets 20, 25 and anchor bolts 21.

[0013] 2 and 3, the guide rail 16 is fixed to the side walls 3c and 3d using brackets 20 and 22, an anchor bolt 21, a rail clip 23, and a bolt 24. Specifically, the bracket 20 is fixed to the side wall 3c or the side wall 3d using the anchor bolt 21. The bracket 22 is welded to the bracket 20. The guide rail 16 is sandwiched between the bracket 22 and the rail clip 23. The rail clip 23 is fastened to the bracket 22 using the bolt 24.

[0014] 2 and 4, the guide rail 17 is fixed to the side wall 3b using a bracket 25, an anchor bolt 21, a rail clip 28, and a bolt 24. Specifically, the bracket 25 is fixed to the side wall 3b using the anchor bolt 21. The guide rail 17 is sandwiched between the bracket 25 and the rail clip 28. The rail clip 28 is fastened to the bracket 25 using the bolt 24.

[0015] 5, the guide rail 16 may be fixed to the side walls 3a and 3b using brackets 20 and 22, anchor bolts 21, rail clips 23, bolts 24, and an intermediate beam 18. The bracket 20 is fixed to the side walls 3a and 3b using the anchor bolts 21. The intermediate beam 18 is welded to the bracket 20. The bracket 22 is welded to the intermediate beam 18. The guide rail 16 is sandwiched between the bracket 22 and the rail clip 23. The rail clip 23 is fastened to the bracket 22 using the bolts 24. The guide rail 17 may also be fixed to the side walls 3a and 3b using the brackets 20 and 22, anchor bolts 21, rail clips 23, bolts 24, and an intermediate beam 18, similar to the guide rail 16.

[0016] The anchor bolt interval measuring device 30 of this embodiment will be described with reference to Figures 6 to 12. Below, as an example, measurement of the interval between anchor bolts 21 for fixing an elevator guide rail using the anchor bolt interval measuring device 30 will be described. The anchor bolt interval measuring device 30 comprises a main body 31, a support member 50, a convex rule 53, a tape feed mechanism 60, an operation unit 34, a first wire 70, a second wire 72, and a claw 59. The anchor bolt interval measuring device 30 may further comprise a wire guide 74.

[0017] 6 and 7, the main body 31 includes a rod member 32 and a grip portion 33.

[0018] The rod member 32 includes a first end and a second end opposite to the first end. The rod member 32 may be extendable. The rod member 32 has a telescopic structure. Specifically, the rod member 32 includes hollow rod portions 32a, 32b, 32c, 32d, and 32e. The inner diameter of the hollow rod portion 32c is larger than the outer diameter of the hollow rod portion 32b. The inner diameter of the hollow rod portion 32d is larger than the outer diameter of the hollow rod portion 32c. The inner diameter of the hollow rod portion 32e is larger than the outer diameter of the hollow rod portion 32d. The first end of the rod member 32 is, for example, the hollow rod portion 32a. The second end of the rod member 32 is, for example, the hollow rod portion 32e.

[0019] The main body 31 may further include a swivel joint 32r. The swivel joint 32r is disposed between the first end and the second end. Specifically, the swivel joint 32r is connected to the hollow rod portion 32a and the hollow rod portion 32b. Due to the swivel joint 32r, the orientation of the hollow rod portion 32a relative to the hollow rod portions 32b, 32c, 32d, and 32e is adjustable (see FIG. 16). A groove 32g (see FIG. 12) is formed in the rod member 32 (e.g., the hollow rod portion 32a).

[0020] The grip portion 33 is provided on a second end (for example, hollow rod portion 32e) of the rod member 32. When an inspection worker uses the anchor bolt gap measuring device 30 to measure the gap between the anchor bolts 21, the inspection worker grips the grip portion 33.

[0021] 11, the support member 50 is, for example, a plate-like member. The support member 50 supports a part of the bar member 32 (for example, the hollow bar portion 32a) and a case 55 of the convex rule 53. The support member 50 includes a main surface 51. The main surface 51a is a mounting surface for the case 55 of the convex rule 53. A recess 52 is formed in the support member 50. The support member 50 is attached to a first end portion of the bar member 32 (for example, the hollow bar portion 32a). The first end portion of the bar member 32 (for example, the hollow bar portion 32a) is fitted into the recess 52, for example.

[0022] 6, 7, 11 and 12, the convex rule 53 includes a convex tape 54, a case 55, a drum 56, a winding spring 57, and a claw 58.

[0023] The convex tape 54 has a curved shape in a cross section perpendicular to the longitudinal direction of the convex tape 54. The convex tape 54 is formed of a metal such as steel. The convex tape 54 has flexibility that allows it to be wound up and uprightness. The convex tape 54 is disposed between a first frame 61 and a second frame 63.

[0024] The case 55 is capable of housing the convex tape 54. The case 55 is placed on the support member 50 (specifically, the main surface 51). The drum 56 is housed in the case 55 so as to be freely rotatable. The winding spring 57 is housed in the case 55. The winding spring 57 is, for example, a power spring, and biases the drum 56 in a direction in which the convex tape 54 is wound up. The winding spring 57 rotates the drum 56 in the direction in which the convex tape 54 is wound up, and the convex tape 54 is wound up around the drum 56. The claw 58 is formed on the convex tape 54 (for example, at the tip of the convex tape 54).

[0025] The claw 59 is provided on the support member 50 (specifically, on the main surface 51). The claw 59 is disposed between the claw 58 and the first end of the rod member 32 (for example, the hollow rod portion 32a).

[0026] 6, 7, 11 and 12, the tape feeding mechanism 60 can be operated by the operating unit 34 to feed the convex tape 54. The tape feeding mechanism 60 is provided, for example, on the rod member 32 (for example, the first end (for example, the hollow rod portion 32a)). The tape feeding mechanism 60 includes a first link 61, a second link 63, and a biasing member 65.

[0027] The first link 61 can be rotated by the operating unit 34 and can come into contact with the convex tape 54. Specifically, the first link 61 includes a first link body 61a including a side surface 62, and a first shaft 61b fixed to the first link body 61a. The side surface 62 of the first link body 61a is curved along the convex tape 54. The side surface 62 of the first link body 61a comes into contact with the convex tape 54. The first shaft 61b is provided at a first end of the rod member 32 (e.g., the hollow rod portion 32a). The first shaft 61b may be fixed to the first end of the rod member 32 (e.g., the hollow rod portion 32a).

[0028] The second link 63 is biased toward the first link 61 and can contact the convex tape 54. Specifically, the second link 63 includes a second link body 63a and a second shaft 63b fixed to the second link body 63a. The second shaft 63b is provided at a first end (e.g., the hollow rod portion 32a) of the rod member 32. The second shaft 63b is inserted into a groove 32g of the rod member 32. The second shaft 63b can move in the longitudinal direction of the rod member 32. The biasing member 65 is, for example, a compression spring. The biasing member 65 biases the second shaft 63b toward the first link 61. The convex tape 54 is sandwiched between the first link 61 and the second link 63. The second link 63 is a driven link that can rotate in response to the rotation of the first link 61 and the movement of the convex tape 54.

[0029] 6, 7 and 12, the first wire 70 includes a first wire end and a second wire end opposite to the first wire end. The first wire end of the first wire 70 is connected to the first spool 35. The second wire end of the first wire is connected to the second spool 36. The first wire 70 is in contact with the first top 61 (e.g., the first shaft 61b). The first wire 70 may be wound around the first shaft 61b. When the first wire 70 is moved by the operation unit 34, the first top 61 rotates.

[0030] The second wire 72 is, for example, a chain wire. The second wire 72 includes a third wire end and a fourth wire end opposite to the third wire end. The third wire end of the second wire 72 is connected to the second link 63 (for example, the second shaft 63b). For example, one chain portion of the chain wire is hooked to the second shaft 63b. The second wire 72 is connected to the lever 40. For example, when the rod member 32 is extendable, the second wire 72 is detachably connected to the lever 40. For example, one chain portion of the chain wire is hooked to the lever 40. The fourth wire end of the second wire 72 is fixed to the grip portion 33, for example. When the second wire 72 is pulled by the operating portion 34 (for example, the lever 40), the second link 63 moves away from the first link 61 against the biasing force of the biasing member 65, and moves away from the convex tape 54.

[0031] 6 and 7, the wire guide 74 is provided on the rod member 32. The wire guide 74 guides the first wire 70 and the second wire 72 to prevent the first wire 70 and the second wire 72 from becoming entangled with each other. The wire guide 74 has, for example, a ring shape or a rod shape.

[0032] 6 to 10, the operation unit 34 is provided on a second end (e.g., hollow rod portion 32b) of the rod member 32. The operation unit 34 includes, for example, a first spool 35, a second spool 36, a spool operation unit 39, a spool holding member 41, a clutch member 43, and a lever 40. The operation unit 34 may further include wires 42, 44.

[0033] The first spool 35 is rotatably attached to the rod member 32 (for example, the second end (for example, the hollow rod portion 32b)). The first spool 35 is connected to a first wire end of the first wire 70. As shown in FIG. 9, the first spool 35 is biased in a direction to wind up the first wire 70 by a biasing member 35b such as a power spring.

[0034] The spool holding member 41 is biased toward the first spool 35 by a biasing member 45 such as a compression spring. When the lever 40 is released, the biasing force of the biasing member 45 causes the spool holding member 41 to press the first spool 35 or the first wire 70 wound around the first spool 35. The spool holding member 41 prevents the first spool 35 from freely rotating. When the spool holding member 41 presses the first spool 35 or the first wire 70 wound around the first spool 35, the first spool 35 rotates only when the second spool 36 rotates by a predetermined angle and the first wire 70 is wound around the second spool 36 by a predetermined length.

[0035] When the lever 40 is pressed down, the spool holding member 41 moves away from the first spool 35 and the first wire 70 wound around the first spool 35, against the biasing force of the biasing member 45. When the spool holding member 41 is away from the first spool 35 and the first wire 70 wound around the first spool 35, the first spool 35 is rotated in the direction of winding up the first wire 70 by the biasing member 35b.

[0036] The second spool 36 is rotatably attached to the rod member 32 (eg, the second end (eg, hollow rod portion 32b)). The second spool 36 is connected to a second wire end of the first wire 70.

[0037] The second spool 36 can be operated by a spool operating part 39. The spool operating part 39 is, for example, a trigger. Referring to Fig. 10, the spool operating part 39 is connected to a ratchet pawl 38. A ratchet gear 37b is formed on a shaft 37a of the second spool 36. The ratchet gear 37b and the ratchet pawl 38 form a ratchet mechanism. The spool operating part 39 is connected to the ratchet pawl 38.

[0038] The clutch member 43 connects or disconnects the second spool 36 and the spool operating portion 39 to or from each other.

[0039] Specifically, the clutch member 43 is biased toward the second spool 36 by a biasing member 45 such as a compression spring. When the lever 40 is released, the clutch member 43 presses the second spool 36 or the first wire 70 wound around the second spool 36 by the biasing force of the biasing member 45. The clutch member 43 connects the second spool 36 to the spool operating unit 39. Specifically, the clutch member 43 engages the ratchet gear 37b with the ratchet gear 37b. When the spool operating unit 39 is operated once (for example, the trigger is pulled once), the second spool 36 rotates by a predetermined angle. The first wire 70 moves and is wound around the second spool 36 by a predetermined length. The movement of the first wire 70 rotates the first frame 61, and the convex tape 54 in contact with the first frame 61 is fed.

[0040] When the lever 40 is pressed down, the clutch member 43 moves away from the second spool 36 and the first wire 70 wound around the second spool 36 against the biasing force of the biasing member 45. The second spool 36 is released from the spool operating portion 39. Specifically, the engagement between the ratchet gear 37b and the ratchet pawl 38 is released. The second spool 36 can rotate freely.

[0041] The spool holding member 41 and the clutch member 43 can be interlocked with the lever 40. Specifically, the wire 42 is connected to the spool holding member 41 and the lever 40. The wire 44 is connected to the clutch member 43 and the lever 40. When an inspection worker presses down the lever 40, the spool holding member 41 is pulled by the wire 42, and the clutch member 43 is pulled by the wire 44. The spool holding member 41 moves away from the first spool 35 and the first wire 70 wound around the first spool 35 against the biasing force of the biasing member 45. The clutch member 43 moves away from the second spool 36 and the first wire 70 wound around the second spool 36 against the biasing force of the biasing member 45. When the inspection worker releases the lever 40, the spool holding member 41 presses the first spool 35 or the first wire 70 wound around the first spool 35 due to the biasing force of the biasing member 45, and the clutch member 43 presses the second spool 36 or the first wire 70 wound around the second spool 36 due to the biasing force of the biasing member 45.

[0042] The second top 63 may further be linked to the lever 40. Specifically, the second wire 72 is connected to the second top 63 and the lever 40. When the inspection worker presses down the lever 40, the second top 63 is pulled by the second wire 72. The second top 63 moves away from the first top 61 against the biasing force of the biasing member 65. When the inspection worker releases the lever 40, the second top 63 moves toward the first top 61 due to the biasing force of the biasing member 65.

[0043] A method of measuring the pitch D of the anchor bolts 21, 21 in this embodiment using the anchor bolt interval measuring device 30 will be described with reference to Figs.

[0044] 13 to 19, the method for measuring the pitch D of the anchor bolts 21, 21 in this embodiment is to measure the outer distance d 1 The method includes a step S1 of measuring

[0045] Specifically, the anchor bolt gap measuring device 30 is stored in a storage space such as the machine room 8 (see FIG. 1). An inspection worker carries the anchor bolt gap measuring device 30 out of the storage space. As shown in FIG. 14A and FIG. 14B, the rod member 32 is contracted during storage and transportation of the anchor bolt gap measuring device 30. This makes it easier to transport the anchor bolt gap measuring device 30. The anchor bolt gap measuring device 30 can be stored in a smaller space. When the rod member 32 is contracted as shown in FIG. 14A and FIG. 14B, the excess portion of the second wire 72 is wound around the gripping portion 33, for example. A first portion of the second wire 72 is connected to the lever 40. For example, when the second wire 72 is a chain wire, a first chain portion of the chain wire is hooked to the lever 40.

[0046] The inspection worker holds the anchor bolt interval measuring device 30 and stands on the ceiling of the car 10 (see FIG. 1). With reference to FIG. 7 and FIG. 15, the inspection worker pushes down the lever 40. The spool holding member 41, the clutch member 43, and the second link 63 are interlocked with the lever 40. Specifically, the spool holding member 41 moves away from the first spool 35 and the first wire 70 wound around the first spool 35. The clutch member 43 moves away from the second spool 36 and the first wire 70 wound around the second spool 36. The engagement between the ratchet gear 37b and the ratchet pawl 38 is released, and the connection between the second spool 36 and the spool operating unit 39 is released. The second link 63 moves away from the first link 61 and moves away from the convex tape 54. The inspection worker removes the first portion of the second wire 72 (for example, the first chain portion of the chain wire) from the lever 40.

[0047] 7 and 15, the inspection worker uses a convex tape 54 to measure the distance between the anchor bolts 21 (in step S1, the outer distance d 1) can be measured. As the rod member 32 is extended, the excess portion of the second wire 72 is unwound from the gripping portion 33 and shortened. The inspection worker connects a second portion of the second wire 72, which is different from the first portion of the second wire 72, to the lever 40. For example, when the second wire 72 is a chain wire, the inspection worker hooks a second chain portion of the chain wire, which is different from the first chain portion of the chain wire, to the lever 40. As shown in FIG. 16, the orientation of the first end of the rod member 32 (e.g., the hollow rod portion 32a) may be adjusted depending on the positions of the anchor bolts 21, 21.

[0048] Referring to FIG. 17, the inspection worker releases the lever 40. The spool holding member 41, the clutch member 43, and the second link 63 are interlocked with the lever 40. Specifically, the spool holding member 41 contacts and presses the first spool 35 or the first wire 70 wound around the first spool 35 by the biasing force of the biasing member 45. The clutch member 43 contacts and presses the second spool 36 or the first wire 70 wound around the second spool 36 by the biasing force of the biasing member 45. The ratchet gear 37b engages with the ratchet pawl 38, and the second spool 36 is connected to the spool operating part 39. The second link 63 moves toward the first link 61 by the biasing force of the biasing member 65 and contacts the convex tape 54. The convex tape 54 is sandwiched between the first link 61 and the second link 63.

[0049] 18, the inspection worker operates the spool operating unit 39 at least once. In one example, the inspection worker pulls a trigger, which is an example of the spool operating unit 39, at least once. When the inspection worker operates the spool operating unit 39 once, the second spool 36 rotates by a predetermined angle, and the first wire 70 is wound onto the second spool 36 by a predetermined length. The first wire 70 moves by the predetermined length, causing the first frame 61 to rotate. When the first frame 61 rotates, the convex tape 54 is fed out by a predetermined length.

[0050] One anchor bolt 21 includes an inner side surface 21b facing the other anchor bolt 21 and an outer side surface 21a opposite to the inner side surface 21b. The inspection worker checks the interval between the anchor bolts 21 (in step S1, the outer interval d 1 ) can be measured. Specifically, the inspection worker operates the spool operating part 39 multiple times until the claw 59 is positioned farther from the rod member 32 than the outer side surface 21a of the anchor bolt 21 distal from the rod member 32. The inspection worker brings the claw 59 into contact with the outer side surface 21a of the anchor bolt 21 proximal to the rod member 32.

[0051] 19, an inspector presses down lever 40. Spool holder 41, clutch member 43 and second link 63 move in conjunction with lever 40.

[0052] Specifically, the second link 63 moves away from the first link 61 and away from the convex tape 54. Because the winding spring 57 biases the drum 56 in a direction to wind up the convex tape 54, the convex tape 54 is wound onto the drum 56. When the claw 58 comes into contact with the outer side surface 21a of the anchor bolt 21 distal to the rod member 32, the convex tape 54 stops.

[0053] The spool holding member 41 moves away from the first spool 35 and the first wire 70 wound around the first spool 35. The clutch member 43 moves away from the second spool 36 and the first wire 70 wound around the second spool 36. The ratchet gear 37b and the ratchet pawl 38 are disengaged from each other, and the second spool 36 and the spool operating unit 39 are disconnected from each other. The second spool 36 can rotate freely. When the convex tape 54 is wound around the drum 56, the first top 61 rotates. The rotation of the first top 61 moves the first wire 70 toward the first spool 35. The first spool 35 is biased by the biasing member 35b in a direction to wind the first wire 70. The first wire 70 is wound around the first spool 35.

[0054] The inspection worker reads the first scale of the convex tape 54 corresponding to the claw 58 and the second scale of the convex tape 54 corresponding to the claw 59. From the first scale and the second scale, the inspection worker can determine the outer distance d 1 get.

[0055] 13, 20 and 21, the method of measuring the pitch D of the anchor bolts 21, 21 in this embodiment is to measure the diameter d 2 The step S2 measures the diameter d of the anchor bolt 21. 2 is the distance between the outer side surface 21a of the anchor bolt 21 and the inner side surface 21b of the anchor bolt 21. The diameter d of the anchor bolt 21 2 Step S2 is to measure the outer distance d between the anchor bolts 21, 21. 1 This is similar to step S1 for measuring the position of the claw 58, however, the position of the claw 58 is different.

[0056] As shown in FIG. 20, in step S2, the inspection worker releases the lever 40. The inspection worker checks the interval between the anchor bolts 21 (in step S2, the diameter d 2 ) can be measured. Specifically, the inspection worker operates the spool operating part 39 at least once until the claw 59 is positioned between the inner side surface 21b of the anchor bolt 21 proximal to the rod member 32 and the inner side surface 21b of the anchor bolt 21 distal to the rod member 32. The inspection worker brings the claw 59 into contact with the outer side surface 21a of the anchor bolt 21 proximal to the rod member 32.

[0057] As shown in FIG. 21, in step S2, the inspection worker presses down the lever 40. The convex tape 54 is wound up around the drum 56. When the claw 58 comes into contact with the inner side surface 21b of the anchor bolt 21 proximal to the rod member 32, the convex tape 54 stops. The inspection worker reads the first graduation on the convex tape 54 corresponding to the claw 58 and the second graduation on the convex tape 54 corresponding to the claw 59. From the first graduation and the second graduation, the inspection worker can determine the diameter d of the anchor bolt 21. 2 get.

[0058] 13, the method for measuring the pitch D of the anchor bolts 21, 21 of this embodiment includes a step (S3) of calculating the pitch D of the anchor bolts 21, 21. As shown in FIG. 6, the pitch D of the anchor bolts 21, 21 is the distance between the centers of the anchor bolts 21, 21 adjacent to each other. The pitch D of the anchor bolts 21, 21 is calculated by multiplying the outer distance d 1 and the diameter d of the anchor bolt 21 2 Thus, the pitch D of the anchor bolts 21, 21 can be measured using the anchor bolt spacing measurer 30.

[0059] When the measurement of the pitch D of the anchor bolts 21, 21 is completed, the inspection worker removes the anchor bolt interval measuring device 30 from the anchor bolts 21, 21. The convex tape 54 is further wound around the drum 56. The claw 58 comes into contact with the claw 59, and the winding of the convex tape 54 is completed. The inspection worker removes the second portion of the second wire 72 (e.g., the second chain portion of the chain wire) from the lever 40. The inspection worker retracts the bar member 32. The inspection worker presses down the lever 40. The inspection worker connects the first portion of the second wire 72 to the lever 40. For example, when the second wire 72 is a chain wire, the inspection worker hooks the second chain portion of the chain wire, which is different from the first chain portion of the chain wire, onto the lever 40. The inspection worker winds the excess portion of the second wire 72 around the gripping portion 33. 14A and 14B, the anchor bolt gap measuring device 30 becomes compact. The inspection worker carries the anchor bolt gap measuring device 30 into a storage space such as the machine room 8 (see FIG. 1).
