Description

Technical Field

[0001] This invention relates to bicycle parking devices. Background Technology

[0002] Patent Document 1 describes a two-tiered bicycle parking system comprising: multiple sliding racks mounted along the long sides of fixed guide rails arranged laterally in a straight line relative to a reference plane when viewed from above, and capable of sliding on the fixed guide rails; and a lifting rack supported by each pillar erected laterally at certain intervals from the reference plane, protruding cantilevered along the long side, and capable of lifting and lowering along the pillars. The lifting rack can move between the upper and lower tiers within the space created by the lateral sliding of the sliding racks located on the lower tier. In this two-tiered bicycle parking system, each lifting rack constitutes a bicycle parking device that moves up and down along its corresponding pillar via a lifting drive unit.

[0003] The lifting drive unit includes an electric motor as the drive source and a chain drive mechanism. The chain drive mechanism has: sprockets, which are respectively supported on the upper and lower interior of the support column; and a flat link chain, which is wound around these sprockets inside the support column 21 and connected to the lifting frame at both ends. The electric motor has a separate structure that rotates the upper sprocket via a worm gear.

[0004] Existing technical documents Patent documents Patent Document 1: Japanese Patent No. 7186480 Summary of the Invention The problem that the invention aims to solve The bicycle parking device with vertical lifting mechanism in Patent Document 1 has a large number of components, making on-site assembly difficult. Specifically, the lifting drive mechanism includes a gas spring, which serves as a drive source in addition to the electric motor, to supplement the electric motor's driving force. This requires assembling not only the mechanisms involved in the electric motor but also the mechanisms involved in the gas spring. If various safety mechanisms and wiring are added, the number of components further increases, complicating assembly and increasing its difficulty. Furthermore, the number of components directly impacts cost.

The electric drive unit has: An electric cylinder, which uses the rotation of a motor to move a rod forward and backward along the support; A winding transmission mechanism includes: a fixed pulley disposed on the upper side of the support column; a movable pulley disposed on the front end side of the rod; and a rope, one end of which is connected to the movable body, the rope extending upward from its connection point being wound around the fixed pulley and the movable pulley, and the other end of its front portion being fixed to the support column. The winding transmission mechanism uses the rope to correspondingly move the movable body up and down along the support column in accordance with the forward and backward movement of the rod, thereby raising and lowering the lifting frame.

Detailed Implementation

[0032] Hereinafter, embodiments of the present invention are listed and illustrated. Furthermore, the features of [1] to

[10] illustrated below can be combined in any way without contradiction.

[0033] [1] A bicycle parking device comprising: a support column erected vertically relative to a reference plane; a movable body capable of rising and falling along the support column; a lifting frame with a front cantilever supported on the movable body and capable of carrying a bicycle horizontally and extending in a front-rear direction; and an electric drive unit for raising and lowering the lifting frame and the movable body along the support column when the bicycle is in a mounted or unmounted state, wherein... The electric drive unit has: An electric cylinder, which uses the rotation of a motor to move a rod forward and backward along the support; A winding transmission mechanism includes: a fixed pulley disposed on the upper side of the support column; a movable pulley disposed on the front end side of the rod; and a rope, one end of which is connected to the movable body, the rope extending upward from its connection point being wound around the fixed pulley and the movable pulley, and the other end of its front portion being fixed to the support column. The winding transmission mechanism uses the rope to correspondingly move the movable body up and down along the support column in accordance with the forward and backward movement of the rod, thereby raising and lowering the lifting frame. A control device is provided on the support column to control the motor in order to raise and lower the movable body and the lifting frame.

[0034] Electric cylinders are formed with a known structure including a motor (electric motor) and a mechanism (lead screw, etc.) that converts the rotational motion of the motor into linear motion, efficiently converting the rotation of the motor into linear action, causing a rod to extend / retract from the cylinder body (cylinder housing). The structure for extending / retracting this rod is suitable for using a winding transmission mechanism with a movable pulley, which can reduce the traction force required to lift the lifting frame to less than half. In the bicycle parking device described above [1], a winding transmission mechanism using both a fixed pulley and a movable pulley is provided along with the electric cylinder, thereby ensuring a certain level of driving force without the need for an auxiliary drive source and related mechanisms. Furthermore, the electric cylinder can be mounted as a compact, single device in the bicycle parking device. Therefore, compared to the past, the number of parts is greatly reduced, the structure is simplified, and assembly is facilitated.

[0035] [2] The bicycle parking device as described in [1], wherein, The electric cylinder is fixed to the upper side of the support column by means of the rod extending downward from the cylinder body. The rope extends upward with one end connected to the movable body, is wound around the fixed pulley at its front and extends downward, is wound around the movable pulley at its front and extends upward, and the other end of the rope at its front is fixed to the support.

[0036] In the bicycle parking device described above [2], the electric cylinder is located on the upper part of the support column, and the rod extends downward. In this case, the rod with the electric cylinder at the lower part of the support column has sufficient space to move forward and backward in order to raise and lower the lifting frame. Therefore, the winding transmission mechanism can be constructed with a minimal structure using a single movable pulley and a single fixed pulley, thus reducing the number of parts and making assembly easier.

[0037] [3] The bicycle parking device according to [1], wherein, The electric cylinder is fixed to the lower side inside the support column by means of the rod extending upward from the cylinder body. The rope extends upward with one end connected to the movable body, is wound around the fixed pulley at its front and extends downward, is wound around the movable pulley at its front and extends upward, and the other end of the rope at its front is fixed to the support.

[0038] In the bicycle parking device described above [3], the electric cylinder is located near the ground at the bottom of the support post, and a rod extends from the upper end of the cylinder body. The bicycle parking device includes a movable pulley and a fixed pulley. Therefore, it is possible to create a bicycle parking device that uses a small and inexpensive electric cylinder.

[0039] [4] The bicycle parking device according to [1], wherein, The electric cylinder is fixed to the lower side inside the support column by means of the rod extending upward from the cylinder body. The rope extends upward with one end connected to the movable body, its front portion is wound around a first fixed pulley constituting the fixed pulley and extends downward, its front portion is wound around a first movable pulley constituting the movable pulley and extends upward, its front portion is wound around a second fixed pulley constituting the fixed pulley (different from the first fixed pulley) and extends downward, its front portion is wound around a second movable pulley constituting the movable pulley (different from the first movable pulley) and extends upward, and its other end is fixed to the support column at its front portion.

[0040] In the bicycle parking device described in [4] above, the electric cylinder is located near the ground at the bottom of the support column, and the rod extends from the upper end of the cylinder body. However, to facilitate the loading of bicycles, it is preferable to place the lifting frame as close to the ground as possible when it is in the lower position. Therefore, it is necessary to shorten (lower) the length (height) of the cylinder body of the electric cylinder. If the length of the cylinder body is shortened (lowered), the maximum stroke of the rod also becomes shorter, and the lifting distance of the lifting frame may be insufficient. In the bicycle parking device described in [4] above, a structure with two or more movable pulleys is included in the winding transmission mechanism. Thus, relative to the lifting distance of the lifting frame from the lower position to the upper position, the extension stroke of the rod only needs to be less than 1 / 4 of the lifting distance, and the force also only needs to be less than 1 / 4. Therefore, it is possible to create a bicycle parking device that uses a small and inexpensive electric cylinder.

[0041] [5] The bicycle parking device according to [1], wherein, The bicycle parking device has: A remote operating device includes a remote operating unit comprising a raising operating unit for raising the movable body and the lifting frame along the support column, a lowering operating unit for lowering the movable body and the lifting frame, and a stopping operating unit for stopping the movable body and the lifting frame. After independently operating the raising operating unit, the lowering operating unit, and the stopping operating unit, the remote operating device wirelessly transmits the corresponding operating signals. The receiving unit wirelessly receives the operation signal. The control device controls the motor according to the operation signal received by the receiving unit, so as to raise and lower the lifting frame and the movable body. The remote operating device is located at the rear end of the lifting frame, and is either fixed to the rear end or detachably housed in a retainer located at the rear end. The control device and the receiving part, together with the wiring connected to them, are located on the support side, but not on the lifting frame.

[0042] In conventional electric lift bicycle parking systems, an operation switch related to the lifting of the lift frame is located at the rear end of the lift frame, and a wiring connected to the operation switch is laid (wound) on the lower surface of the lift frame. Furthermore, this wiring extends from the lift frame to the support column and connects to a control device located on the support column, thus requiring a length sufficient to accommodate the lifting distance of the lift frame. Additionally, a mechanism is needed to smoothly extend / retract such a long wiring according to the lifting movement of the lift frame. In the bicycle parking system described above [5], the lifting / stopping operation of the lift frame is performed using a remote control (remote operating device). The operation switch related to the lifting of the lift frame is eliminated, and there is no wiring. Furthermore, a mechanism for smoothly extending / retracting the wiring is not required. Therefore, the number of bicycle parking components is greatly reduced, the structure is simplified, and assembly becomes easier. Furthermore, the weight of the lift frame is reduced, which also contributes to increased driving force.

[0043] [6] The bicycle parking device according to [1], wherein, The bicycle parking device has an anomaly detection unit, which is used to detect predetermined abnormal states during the lifting and lowering movements of the movable body and the lifting frame. If an abnormal state is detected based on the detection result of the abnormality detection unit, the control device controls the motor to stop or reverse the movable body during the lifting motion. The control device and the anomaly detection unit, together with the wiring connected to them, are located on the side of the support column, but not on the lifting frame.

[0044] In the bicycle parking device described above [6], there are detection units and control devices for detecting abnormal conditions, but they are all installed on the support column and not on the lifting frame. Therefore, these detection units and control devices include wiring connected to them and are not affected by the lifting movement of the lifting frame, so they can be easily installed on the support column.

[0045] [7] The bicycle parking device according to [6], wherein, The anomaly detection unit is a current detection unit that detects the current flowing through the motor. At least during the ascent of the lifting frame and the movable body, if the current detected by the current detection unit exceeds a predetermined value, the control device controls the motor to stop or reverse the descent of the lifting frame and the movable body.

[0046] In the bicycle parking system described above [7], when an overload is detected in the motor, it is sensed, and the drive of the electric cylinder is stopped, or a reversing action is performed in the opposite direction to the overload, thus eliminating the motor overload condition. For example, during the raising of the bicycle-mounted lift, if the bicycle comes into contact with the handlebars of a bicycle mounted on the upper position of the lift on an adjacent support, thus hindering the raising of the lift, the current flowing in the motor exceeds a predetermined value. Therefore, this can be sensed as an abnormal condition, and the drive of the electric cylinder is stopped or reversed. In this case, there is no need to significantly increase the number of components in the bicycle parking system, nor is it necessary to add components to the lift.

[0047] [8] The bicycle parking device according to [6], wherein, The anomaly detection unit is a slack sensing unit that senses the slack of the rope in the winding transmission mechanism. At least during the descent of the lifting frame and the movable body, if the slack sensing unit detects slack, the control device controls the motor to stop or reverse the upward movement of the lifting frame and the movable body.

[0048] In the bicycle parking device described above [8], for example, during the descent of the lifting frame, when the lifting frame comes into contact with an obstacle and obstructs the descent, the cable becomes slack. Therefore, this slack can be sensed to stop or reverse the drive of the electric cylinder. In this case, there is no need for a structure that significantly increases the number of components in the bicycle parking device, nor is it necessary to add components to the lifting frame.

[0049] [9] The bicycle parking device according to [8], wherein, The relaxation sensing unit has: The control lever, relative to the force-applying section of the rope forming a range from the end connected to the movable body to the initial fixed pulley (i.e., the fixed pulley on the movable body side), is arranged to be pushed out by relaxing the force-applying section rearward; and The sensing unit is configured to output a predetermined detection signal to the control device when the switch button is pressed by the extended joystick.

[0050] For example, during the descent of the lifting frame, when the lifting frame comes into contact with an obstacle and hinders descent, the cable that pulls the movable body supporting the lifting frame is prone to slack on the side near the movable body. Furthermore, it is known that slack is likely to occur in the section of the cable from the movable body to the initial fixed pulley (the fixed pulley on the movable body side). In the bicycle parking device described above [9], a slack-sensing lever is positioned opposite the section of the cable where slack is likely to occur, thus reliably sensing slack and immediately stopping or reversing the drive of the electric cylinder. In this case, a structure that significantly increases the number of components in the bicycle parking device is not required, nor is it necessary to add components to the lifting frame.

[0051] Furthermore, in the bicycle parking device described above [9], the control lever can be positioned on the rear side of the movable body-side fixed pulley in the longitudinal direction of the force-applying section of the rope, and can also be positioned near the position where the force-applying section leaves the outer peripheral groove of the movable body-side fixed pulley in the vertical direction. During the descent of the lifting frame, when the lifting frame contacts an obstacle and obstructs descent, the rope slackens in the rearward direction of the initial fixed pulley (movable body-side fixed pulley), starting near the position where it contacts the outer peripheral groove of the fixed pulley. By sensing the slackening of the rope near the position that becomes the starting point of this slackening, slackening can be sensed quickly and reliably.

[0052]

[10] The bicycle parking device according to [1], wherein, The lifting frame and the movable body move up and down on the support column between a predetermined lower position for loading and unloading bicycles relative to the lifting frame, and a predetermined upper position for the lifting frame to wait in an unused state when the bicycle is loaded or unloaded. The bicycle parking device has the following features: The upper position sensing unit senses the position of the lifting frame in the upper position; and Reporting device for issuing warning reports. If the upper position sensor does not detect that the lifting frame is in the upper position, the control device will continuously issue a warning report. The control device and the reporting device, together with the wiring connected to them, are located on the side of the support column, but not on the lifting frame.

[0053] In the bicycle parking device described in

[10] above, the device is used when the lifting rack is in the upper position of the support column as if it were not in use. Even when the lifting rack is in a stable state of stopping in the lower position after leaving the upper position, a warning report continues to be issued. That is, during the series of operations performed by the user of the bicycle parking device—from lowering the lifting rack without a bicycle from the upper position to the lower position, from loading the bicycle to returning the rack with the bicycle to the upper position—a warning report is continuously or intermittently issued, and the warning report stops when the lifting rack returns to the upper position and the operation is completed. Thus, the user reliably performs the lifting operation of the lifting rack until the very end, without leaving the device midway through the operation. This encourages the user to be responsible for performing the lifting operation until the very end. Furthermore, in this case, there is no need to significantly increase the number of components in the bicycle parking device, nor is it necessary to add components to the lifting rack.

[0054]

[11] A bicycle parking device comprising: a support column erected vertically relative to a reference plane; a movable body capable of rising and falling along the support column; a lifting frame with a front cantilever supported on the movable body and capable of carrying a bicycle horizontally and extending in a front-rear direction; and an electric drive unit for raising and lowering the lifting frame and the movable body along the support column when the bicycle is in a mounted or unmounted state, wherein... The electric drive unit has: An electric cylinder, which uses the rotation of a motor to move a rod forward and backward along the support; A winding transmission mechanism includes: a fixed pulley disposed on the upper side of the support column; a movable pulley disposed on the front end side of the rod; and a rope, one end of which is connected to the movable body, the rope extending upward from its connection point being wound around the fixed pulley and the movable pulley, and the other end of its front portion being fixed to the support column. This winding transmission mechanism uses the rope to correspondingly move the movable body up and down along the support column in accordance with the forward and backward movement of the rod, thereby raising and lowering the lifting frame. The control device controls the motor to raise and lower the movable body and the lifting frame, and The bicycle parking device has: A remote operating device includes a remote operating unit comprising a raising operating unit for raising the movable body and the lifting frame along the support column, a lowering operating unit for lowering the movable body and the lifting frame, and a stopping operating unit for stopping the movable body and the lifting frame. After independently operating the raising operating unit, the lowering operating unit, and the stopping operating unit, the remote operating device wirelessly transmits the corresponding operating signals. The receiving unit wirelessly receives the operation signal; and An anomaly detection unit is used to detect predetermined abnormal states during the lifting and lowering movements of the movable body and the lifting frame. The control device controls the motor according to the received operation signal to raise and lower the lifting frame and the movable body. On the other hand, if an abnormal state is detected based on the detection result of the abnormality detection unit, the control device controls the lifting frame and the movable body to stop or reverse the lifting motion. The remote operating device is located at the rear end of the lifting frame, and can be either fixed to the rear end or detachably housed in a retainer located at the rear end. The control device, the receiving unit, and the anomaly detection unit, along with the wiring connected to them, are located on the side of the support column, but not on the lifting frame.

[0055] In the bicycle parking device described above

[11] , by providing an electric cylinder, similar to the bicycle parking device described above [1], it is possible to ensure a greater driving force than the previous single structure using a motor, significantly reducing the number of parts, simplifying the construction, and making assembly easier.

[0056] Furthermore, in the bicycle parking device described in

[11] above, the lifting frame is formed into an extremely simple structure with only a structure for mounting the bicycle and a remote control (remote operation device). The lifting frame is the largest movable part in this bicycle parking device and is located in the position most easily accessible to the user. Therefore, in conventional structures, malfunctions associated with the movement of the lifting frame, electrical system malfunctions, and malfunctions caused by user operation are prone to occur. However, in the bicycle parking device described in

[11] above, the lifting frame is greatly simplified and lightweight, making it difficult for these malfunctions to occur.

[0057] On the other hand, in the bicycle parking device described above

[11] , various control functions such as abnormal detection, abnormal response control, and remote control operation control are non-movable parts of the bicycle parking device and are concentrated in a support located far from the user. Therefore, it is less likely to cause malfunctions due to the user or malfunctions caused by the movement of the bicycle parking device. The control device is configured as a circuit board, for example. If it is placed around the motor of the electric cylinder, the wiring connecting them is also shortened, and a very simple bicycle parking device can be constructed in which the control system is concentrated near the motor.

[0058] Thus, a bicycle parking device that sets up a simple structure with only a structure for carrying bicycles and a remote control (remote operation device) as the movable part, and is based on the design concept of centrally setting other control devices and their wiring in the support column, did not exist in the past.

[0059] The following description relates to the first embodiment.

[0060] like Figure 1 The two-level bicycle parking facility 100 shown has a lower bicycle parking device 10 and an upper bicycle parking device 20.

[0061] The lower bicycle parking device 10 includes: a fixed guide rail 11, which is arranged in a straight line along the transverse direction Y set on the reference plane E (mounting surface, ground surface); and a plurality of sliding brackets 12, which are mounted along the long side direction that is orthogonal or oblique to the fixed guide rail 11 when viewed from above, and are capable of sliding on the fixed guide rail 11.

[0062] The upper-level bicycle parking device 20 includes: a plurality of pillars 21, which are erected relative to the reference plane E (the setting surface, the ground surface) along the transverse Y at predetermined intervals (here, equal intervals); and a lifting platform 23 (movable body: see reference). Figure 2 The bicycle BCL is mounted on each support column 21 and can be raised and lowered along the corresponding support column 21; the lifting frame 22 has its front end cantilever supported on the corresponding lifting platform 23 and can carry the bicycle BCL in a horizontal position and extend in the front-rear X direction; and the electric drive unit 24 (see Figure 2 and Figure 12 The corresponding lifting frame 22 is raised and lowered by raising and lowering the corresponding lifting platform 23 along the support column 21. The upper bicycle parking device 20 has the following features: Figures 2-5 The multiple bicycle parking units 1 shown each have a support column 21, a lifting frame 22, a lifting platform 23 and an electric drive unit 24.

[0063] like Figures 2-5 As shown, the lifting frame 22 and lifting platform 23 in each bicycle parking unit 1 are positioned on the support column 21 by an electric drive unit 24 at a predetermined lower position for loading and unloading bicycle BCLs relative to the lifting frame 22. Figure 3 , Figure 4 ), and the predetermined upper position for the unused waiting position of the lifting rack 22 when it is in the mounted or unmounted state of the bicycle BCL (Bike BCL). Figure 2 , Figure 5 The bicycles are raised and lowered as a whole. That is, each bicycle parking device 1 of the upper bicycle parking device 20 is a bicycle parking device of the upper waiting specification.

[0064] The sliding frame 12 and the lifting frame 22 are elongated strips with the long side X-direction for loading and unloading the bicycle BCL. The sliding frame 12 and the lifting frame 22 have a length equivalent to that of a bicycle in the long side X-direction. The sliding frame 12 and the lifting frame 22 are slot-shaped with an open upper surface. An inlet / outlet 4 for loading and unloading the bicycle BCL is formed at the rear (front) end of the sliding frame 12 and the lifting frame 22. Support members 5 (side guards) for preventing the loaded bicycle BCL from tipping over are provided in pairs on both sides of the sliding frame 12 and the lifting frame 22 in the width direction. Additionally, a tire protector 6 for holding the first wheel (e.g., the front wheel) of the loaded bicycle BCL is provided on the front side (side of the support column 21) of the sliding frame 12 and the lifting frame 22.

[0065] like Figure 1 As shown, each sliding bracket 12 can slide on a fixed guide rail 11. The fixed guide rail 11 is a single (or multiple parallel) fixed guide rails arranged in a straight line along the transverse Y direction set on the reference plane E. Each sliding bracket 12 is mounted on the long side direction X, which is orthogonal or obliquely intersecting with the fixed guide rail 11 when viewed from above. Each sliding bracket 12 can slide along the fixed guide rail 11 regardless of whether a bicycle BCL is mounted on it. Furthermore, the fixed guide rail 11 is not limited to being straight.

[0066] In this embodiment, each sliding frame 12 has a plurality of rollers (rolling elements) mounted on the bottom side of its front end, configured to allow passage via a wheel section 13 having these plurality of rollers (see reference). Figures 2-5 This is a lateral sliding movement type that moves laterally along a fixed guide rail 11 set on the reference plane E. Additionally, casters 14 are mounted on the bottom side of the rear end of each sliding frame 12 (see reference). Figures 2-5 The casters 14 are configured to rest on the reference plane E and support the sliding frame 12, and are capable of rolling laterally in the Y direction. Through these structures, each sliding frame 12 is configured to slide laterally in the Y direction.

[0067] like Figure 1 As shown, the lifting frame 22 is supported by each support column 21, which is erected at certain intervals along the transverse direction Y from the reference plane E, in a cantilevered manner projecting towards the long side X. Together with the support columns 21, they form the upper bicycle parking unit 1. The front end of each lifting frame 22 is cantilevered and supported by a lifting platform 23, allowing it to move up and down along the support column 21 via the lifting platform 23. Specifically, as... Figure 2 As shown, each lifting frame 22 can achieve a free space ES (i.e., without) created by the sliding frame 12 located on the lower layer sliding laterally in the Y direction (the arrangement direction of the support columns 21). Figure 2The sliding frame 12 (shown by the dashed line) moves up and down between the upper layer (predetermined upper position) and the lower layer (predetermined lower position). Each lifting frame 22 can move up and down along the support column 21 regardless of whether it carries a bicycle BCL.

[0068] like Figure 1 As shown, each support column 21 is connected and fixed together by a connecting member 2. In this embodiment, each support column 21 has a fixing member 21B fixed to its back side near the middle in the vertical direction Z (see reference). Figure 11 The fixing member 21B extends along the connecting member 2 (lateral Y) on one side of the support column width direction, and is fixed in this extension in the form of surface contact with the connecting member 2. The fixing member 21B to the support column 21 and the fixing member 21B to the connecting member 2 are achieved, for example, by fastening based on bolts, nuts, etc.

[0069] like Figure 6 as well as Figure 12 As shown, each bicycle parking unit 1 includes a lifting frame 22 in either a mounted or unmounted state of a bicycle BCL, and an electric drive unit 24 for raising and lowering the lifting platform 23 along the support column 21. The electric drive unit 24 includes an electric cylinder 41, a winding transmission mechanism 40, and a control device 9.

[0070] The electric cylinder 41 causes the rod 4R to move forward and backward along the support column 21 by rotating the motor 4M (electric motor) which is an electric drive source. Specifically, the electric cylinder 41 is configured with a known structure having a motor 4M and a mechanism (lead screw, etc.) that converts the rotational motion of the motor 4M into linear motion, efficiently converting the rotation of the motor 4M into linear action, causing the rod 4R to extend / retract (move forward and backward) from the cylinder body 4H (cylinder housing).

[0071] The electric cylinder 41 has a cylinder body 4H (cylinder housing) and a rod 4R (piston rod). The electric cylinder 41 is fixed to the upper side of the support column 21 such that the rod 4R extends downward from the cylinder body 4H (cylinder housing). Specifically, as Figure 7 As shown, a shaft portion 21a extending in the front-rear direction X is provided at the upper end 21A of the support column 21. The base end 4A of the electric cylinder 41 is inserted into this shaft portion 21a. An internal trolley 25 (internal movable body) is fixed to the front end of the rod 4R.

[0072] The winding transmission mechanism 40 uses the forward and backward movement of the lever 4R of the electric cylinder 41 to raise and lower the lifting carriage 23 along the support column 21. Specifically, the winding transmission mechanism 40 includes: a fixed pulley 42 disposed on the upper side of the support column 21; a movable pulley 43 disposed on the front end side of the lever 4R; and a rope 44, which is connected to the lifting carriage 23 at one end 44a and extends upward, is wound around the fixed pulley 42 and the movable pulley 43 at its front end, and is fixed to the support column 21 at the other end 44b.

[0073] In this embodiment, the movable pulley 43 is connected to the front end of the rod 4R. Specifically, the movable pulley 43 is connected to the internal trolley 25 located at the front end of the rod 4R. Figure 8 As shown, the movable pulley 43 is inserted into a rotating shaft portion 25a (in this case, a bolt) extending along the width direction y of the support column of the inner trolley 25, and can rotate around the rotating shaft portion 25a. Figure 9 As shown, the fixed pulley 42 is installed inside the support column 21 at a position higher than the cylinder body 4H, i.e., the upper end 21A of the support column 21. Specifically, the fixed pulley 42 is disposed through the opposing plate portions 21A1, 21A1 (see reference) of the upper end 21A of the support column 21. Figure 7 The rotating shaft 21b (here, a bolt) extending along the width direction y of the support is inserted, allowing it to rotate around the rotating shaft 21b.

[0074] The rope 44 is a single rope, wound once around both the fixed pulley 42 and the movable pulley 43. In this embodiment, as... Figure 12 As shown, the rope 44 extends upward with one end 44a directly or indirectly connected to the lifting frame 22, its front end is wound around the fixed pulley 42 and extends downward, its front end is wound around the movable pulley 43 and extends upward, and its front end is fixed to the support column 21. In this embodiment, one end 44a of the rope 44 is directly connected to the lifting trolley 23, which is integrally fixed to the lifting frame 22. Specifically, the hook is fixed to the rope fixing part 23c (see reference) which protrudes from the trolley body of the lifting trolley 23 in the front-rear direction. Figure 7 The other end 44b of the rope 44 is hooked and fixed to the rope fixing part 21c protruding inward at the upper position inside the support 21 (see reference). Figure 9 ).

[0075] The lifting platform 23 is equipped with rollers 23R that roll on guide rails 23G extending in the vertical direction Z on the front surface of the support column 21 (see reference). Figure 11 The internal trolley 25 is equipped with rollers 25R that roll on guide rails 25G extending in the vertical direction Z inside the support column 21 (see reference). Figure 10 ).

[0076] The winding transmission mechanism 40 thus constructed forms a rope transmission mechanism using a movable pulley 43, a fixed pulley 42, and a rope 44. This creates free space on the lower interior side of the support column 21.

[0077] The control device 9 controls the motor 4M to raise and lower the lifting platform 23. On the other hand, during the raising and lowering of the lifting platform 23 and the lifting frame 22, if an abnormality is detected based on the detection result of an abnormality detection unit used to detect predetermined abnormalities, the motor 4M is controlled to stop or reverse the lifting platform 23 during the raising and lowering operation. In this embodiment, as... Figure 13 As shown, the control device 9 is connected to a current detection unit 91, a relaxation sensing unit 92, a reporting unit 93, a receiving unit 94, limit switches 95 and 96 (upper-level position sensing unit and lower-level position sensing unit), an electric motor 4M, etc., which will be described later. The control device 9 is a known microcomputer with a CPU, etc., and stores various programs for controlling the up and down movement of the corresponding lifting frame 22 in a predetermined storage unit. These programs can be executed by the CPU.

[0078] In this embodiment, assuming the weight of the lifting frame 22 and the lifting platform 23 is 10 kg, and the maximum weight of the bicycle BCL is 40 kg, the motor 4M exerts a constant upward driving force capable of pulling (lifting) its total weight when the lifting frame 22 rises. This constant upward driving force of the motor 4M applies regardless of whether the lifting frame 22 is carrying the bicycle BCL. Conversely, when the lifting frame 22 descends, the motor 4M exerts a constant downward driving force regardless of whether the lifting frame 22 is carrying the bicycle BCL.

[0079] The control device 9 is located around the motor 4M of the electric cylinder 41. Specifically, as follows: Figure 7 As shown, the control device 9 is located at the upper end 21A of the support column 21, on the side near the width direction y of the support column, opposite to the cylindrically projecting motor 4M toward the rear of the vehicle. In this embodiment, the control device 9 has a circuit board constituting a microcomputer and a device housing housing the circuit board, which is fixed to the upper end 21A of the support column 21. Various terminals connected to the circuit board are provided in the device housing, and these terminals are connected to external electrical functional units such as the motor 4M, slack sensing unit 92, limit switch 95, limit switch 96, reporting unit 93, and receiving unit 94 via wiring connected to these terminals.

[0080] The current detection unit 91 detects the current flowing through the motor 4M. The current detection unit 91 is provided as a current detection circuit on the circuit board constituting the control device 9. During the ascent of the lifting frame 22 and the lifting carriage 23, if an overcurrent exceeding a predetermined value flows through the motor 4M, the control device 9 controls the motor 4M to reverse and lower (or stop) the lifting frame 22 and the lifting carriage 23. For example, during the ascent of the lifting frame 22, an overcurrent occurs when the ascent is obstructed by an obstacle or the like, or when carrying a weight exceeding a specified specification. The current detection unit 91, together with the control device 9, functions as an overcurrent sensing unit for sensing the overcurrent flowing through the motor 4M, an overload sensing unit for sensing the overcurrent as an overload, and an abnormality detection unit for detecting the overcurrent as a predetermined abnormal state.

[0081] The slack sensing unit 92 is a slack sensing unit that senses the slack of the rope 44 of the winding transmission mechanism 40, and is an anomaly detection unit used to detect this slack as a predetermined abnormal state. The slack sensing unit 92 is fastened to the upper end 21A of the support column 21 via a plate-shaped fixing member 21C using bolts, nuts, etc. Slack in the rope 44 can occur, for example, during the descent of the lifting frame 22, when descent is hindered by obstacles, etc. In this embodiment, the slack sensing unit 92 has a lever 92A and a sensing unit 92B. The lever 92A is a plate-shaped member, such as... Figure 7 as well as Figure 9 As shown, the force-applying section 44A on the lifting platform 23 side of the cable 44 is positioned opposite to it in the rearward direction X. The control lever 92A is configured to be pushed out by the relaxed force-applying section 44A when the cable 44 is relaxed in the rearward direction X. The sensing unit 92B is a microswitch configured such that the switch button 92b is pressed by the pushed-out control lever 92A (see reference). Figure 9 When the switch button 92b is pressed by the lever 92A, the sensing unit 92B outputs a predetermined sensing signal to the control device 9. During the descent of the lifting frame 22 and the lifting platform 23, if the cable 44 winding the transmission mechanism 40 becomes slack, the control device 9 controls the motor 4M to stop the lifting frame 22 and the lifting platform 23 (or reverse and rise).

[0082] In this embodiment, the force-applying section 44A of the rope 44 includes the area near the position r1 where the rope 44 extends from one end 44a connected to the lifting platform 23 to the initial fixed pulley 42, i.e., the fixed pulley 42 (movable body side fixed pulley), where it is wound around and in contact with the fixed pulley 42 (movable body side fixed pulley). Figure 12The lever 92A of the slack sensing unit 92 is located in the force application section 44A of the rope 44, at a position r1 where the force application section 44A moves away from the outer peripheral groove of the fixed pulley 42 in the front-rear direction X and in the vertical direction Z. Figure 12 (near)

[0083] In addition, such as Figure 12 As shown, one or more slack-prevention portions 45 are provided in the fixed pulley 42, which prevent the rope 44 wound along the outer peripheral groove from slackening to the outer peripheral side. The slack-prevention portion 45 is provided in the fixed pulley 42 in the contact interval r where the rope 44 contacts the outer peripheral groove, except for the area near the groove separation position r1 where the rope 44 leaves the outer peripheral groove at the end connected to the lifting platform 23 (rear side in the front-rear direction X). The operating lever 92A of the slack sensing unit 92 is configured to face the portion near the groove separation position r1 of the rope 44 from the outside. The slack-prevention portion 45 prevents the rope 44 from disengaging from the fixed pulley 42 and becomes the starting point for slack in the rope 44. Therefore, when the rope 44 slackens, it is possible to reliably facilitate the disengagement of the rope 44 from the outer peripheral groove in the rear side in the front-rear direction X at the groove separation position r1, and slack can be reliably sensed.

[0084] In this embodiment, the slack-stopping part 45 is a rod-shaped member (in this case, a pin) extending outwards from the outer periphery groove of the fixed pulley 42. In the fixed pulley 42, one slack-stopping part 45 is provided before and after each other in the contact interval r on the upper side where the rope 44 contacts the outer periphery groove. Each slack-stopping part 45 passes through the opposing plate portions 21A1, 21A1 (see reference 21A1) at the upper end 21A of the support column 21. Figure 7 And extends along the width direction y of the support. In addition, in this embodiment, similar to the slack-stopping part 45 for the fixed pulley 42, one or more slack-stopping parts 35 are also provided for the movable pulley 43, which prevent the rope 44 wound along the outer peripheral groove from slacking to the outer peripheral side.

[0085] Limit switches 95 and 96 (upper position sensing unit and lower position sensing unit) are built into electric cylinder 41.

[0086] Limit switch 95 is activated when rod 4R (piston rod) reaches the predetermined extension limit position of cylinder body 4H (cylinder housing) (refer to...). Figure 12 In (a) of the above, a predetermined sensing signal is output to the control device 9. When the control device 9 drives the motor 4M to raise the lifting frame 22 and the lifting carriage 23, it stops the motor 4M upon receiving a sensing signal from the limit switch 95. As a result, the lifting frame 22 stops at a predetermined upper position on the support column 21 (see reference ). Figure 12(a)). That is, the limit switch 95 is an upper position sensing unit that senses the upper position of the lifting frame 22 and the lifting carriage 23.

[0087] Limit switch 96 is activated when rod 4R reaches the predetermined retraction limit position of cylinder body 4H (refer to...). Figure 12 In (b) of the above, a predetermined sensing signal is output to the control device 9. When the control device 9 drives the motor 4M to lower the lifting frame 22 and the lifting carriage 23, it stops the motor 4M upon receiving a sensing signal from the limit switch 96. As a result, the lifting frame 22 stops at a predetermined lower position on the support column 21 (see reference ). Figure 12 (b)). That is, the limit switch 96 is a lower position sensing unit that senses the lower position of the lifting frame 22 and the lifting carriage 23.

[0088] Furthermore, the electric cylinder 41 can be equipped with an intermediate position sensing switch at any position between the extension limit position and the retraction limit position of the rod 4R (piston rod) within the cylinder body 4H (cylinder housing). When the sensing position is set closer to the front than the sensing position of the limit switch 95 built into the electric cylinder 41, and when it is desired that the positions of the lifting frame 22 and the lifting carriage 23 when the rod 4R reaches that position are in the upper position, the intermediate position sensing switch is set to the desired sensing position. Furthermore, the sensing signal from this intermediate position sensing switch is input to the control device 9 instead of the sensing signal from the limit switch 95.

[0089] like Figures 2-5 As shown, the reporting unit 93 is a reporting unit that continuously issues warning reports when the lifting frame 22 and the lifting trolley 23 are not in the upper position. The warning reports here are based on the illumination of lights and the issuance of warning sounds. The reporting unit 93 is controlled by the control device 9. When no sensing signal is input from the limit switch 95, the control device 93 causes the reporting unit 93 to continuously or intermittently issue warning reports; conversely, when a sensing signal is input from the limit switch 95, the reporting unit 93 does not issue warning reports.

[0090] like Figure 13 As shown, the receiver 94 wirelessly receives operation signals wirelessly transmitted from the remote control device 8 (remote controller). For example... Figure 15As shown, the remote operation device 8 has remote operation units 81, 82, and 83 for raising and lowering the lifting frame 22 and the lifting carriage 23 along the support column 21. In this embodiment, the remote operation units 81, 82, and 83 include a raising operation unit 81 for raising the lifting frame 22 and the lifting carriage 23 along the support column 21, a lowering operation unit 83 for lowering the lifting frame 22 and the lifting carriage 23, and a stopping operation unit 82 for stopping the lifting frame 22 and the lifting carriage 23. The remote operation device 8 has a control unit 80 (remote device control unit), remote operation units 81, 82, and 83, and a transmitting unit 84. When the raising operation unit 81, the lowering operation unit 83, and the stopping operation unit 82 are operated individually, the control unit 80 causes the transmitting unit 84 to wirelessly transmit an operation signal corresponding to the operation content. This operation signal is received by the receiving unit 94 and input to the control device 9 corresponding to the receiving unit 94. Based on the identification information contained in the operation signal, the control device 9 determines whether the operation signal is sent from the remote operation device 8 corresponding to itself. If it is sent from the remote operation device 8 corresponding to itself, the control device 9 drives the motor 4M based on the operation content information contained in the operation signal.

[0091] like Figure 14 As shown, the remote operating device 8 is fixed to the rear end 22B of the lifting frame 22. In this embodiment, as... Figure 15 As shown, an opening 22H extending vertically in the Z-direction is formed at the inlet / outlet 4 of the rear end 22B of the lifting frame 22 for loading and unloading bicycles (BCLs). A remote operating device 8 is disposed below this opening 22H. Furthermore, the remote operating device 8 is fixed to the rear end 22B of the lifting frame 22, below its opening 22H, in a position that does not contact the wheels of the loaded bicycle (BCL). The remote operating device 8 is fixed with its operating surface facing upwards, allowing operation from above via its opening 22H.

[0092] The basic operation of the lifting frame 22 in this embodiment will be explained below.

[0093] <Lifting frame 22 is located in the upper position: Figure 2 , Figure 5 > • The lifting platform 23 and the lifting frame 22 are stopped and held in the predetermined upper position by the electric cylinder 41.

[0094] • The rod 4R of the electric cylinder 41 stops when it is extended to its limit position, the internal trolley 25 stops at the predetermined lower position inside the support column, and the lifting trolley 23 stops at the predetermined upper position. Figure 6 (a) and Figure 12 (a) in the middle.

[0095] • Limit switch 95 (upper layer sensor of the lifting frame) is turned on, and limit switch 96 (lower layer sensor of the lifting frame) is turned off.

[0096] • Because limit switch 95 is activated, the reporting department 93 does not issue a warning report.

[0097] <Lifting platform 22 descends: Figure 2 → Figure 3 , Figure 5 → Figure 4 > • The descent control unit 83 of the remote control device 8 is operated, and the electric cylinder 41 is driven based on the drive signal from the control device 9, causing the lifting platform 23 and the lifting frame 22 to descend.

[0098] • The rod 4R of the electric cylinder 41 begins to retract from its extended limit position, causing the internal trolley 25 to rise from its predetermined lower position within the support column, and the lifting trolley 23 to descend from its predetermined upper position. Figure 6 (a) in the middle → Figure 6 (b) Figure 12 (a) in the middle → Figure 12 (b) in the middle.

[0099] • Limit switch 95 (upper layer sensor of the lifting frame) is off, and limit switch 96 (lower layer sensor of the lifting frame) is off.

[0100] Since the limit switch 95 is open, the reporting unit 93 continues to issue warning reports based on the report signal from the control device 9 (see reference). Figure 3 ).

[0101] When the stop operation unit 82 of the remote operation device 8 is operated, the electric cylinder 41 stops driving based on the drive signal from the control device 9, and the lifting frame 22 stops at the current height.

[0102] When the lifting operation unit 81 of the remote operation device 8 is operated, the electric cylinder 41 is driven based on the drive signal from the control device 9, and the lifting frame 22 rises.

[0103] When the relaxation sensing unit 92 is turned on, the electric cylinder 41 reverses its drive based on the drive signal from the control device 9, and the lifting frame 22 rises and returns to the predetermined upper position.

[0104] <Lifting frame 22 is located on the lower level: Figure 3 , Figure 4 > • The lifting platform 23 and the lifting frame 22 are stopped and held at the predetermined lower position by the electric cylinder 41.

[0105] • The rod 4R of the electric cylinder 41 stops when it is retracted to the retraction limit position, the internal trolley 25 stops at the upper position inside the predetermined support, and the lifting trolley 23 stops at the lower position.

[0106] • Limit switch 95 (upper layer sensor of the lifting frame) is off, and limit switch 96 (lower layer sensor of the lifting frame) is on.

[0107] Since the limit switch 95 is open, the reporting unit 93 continues to execute warning reports based on the report signal from the control device 9.

[0108] • It can move bicycles BCL into and out of the lifting frame 22.

[0109] <Lifting platform 22 rises: : Figure 3 → Figure 2 , Figure 4 → Figure 5 > • The lifting operation unit 81 of the remote operation device 8 is operated, and the electric cylinder 41 is driven based on the drive signal from the control device 9, so that the lifting platform 23 and the lifting frame 22 are raised.

[0110] • The rod 4R of the electric cylinder 41 extends from its retracted limit position, causing the internal trolley 25 to descend from its predetermined upper position within the support column, and the lifting trolley 23 to rise from its predetermined lower position. Figure 6 (b) in the middle → Figure 6 (a) Figure 12 (b) in the middle → Figure 12 (a) in the middle.

[0111] • Limit switch 95 (upper layer sensor of the lifting frame) is off, and limit switch 96 (lower layer sensor of the lifting frame) is off.

[0112] Since the limit switch 95 is open, the reporting unit 93 continues to execute warning reports based on the report signal from the control device 9.

[0113] When the stop operation unit 82 of the remote operation device 8 is operated, the electric cylinder 41 stops driving based on the drive signal from the control device 9, and the lifting frame 22 stops at the current height.

[0114] When the descent operation unit 83 of the remote operation device 8 is operated, the electric cylinder 41 is driven based on the drive signal from the control device 9, and the lifting frame 22 descends.

[0115] • When the control device 9 senses an overcurrent based on the detection result of the current detection unit 91, the electric cylinder 41 stops based on the drive signal from the control device 9, and the lifting frame 22 stops at the current height.

[0116] These states and actions remain unchanged whether the lifting frame 22 is in the actual state with the bicycle BCL mounted or in the empty state without the bicycle BCL mounted. However, the weight mounted on the lifting frame 22 differs between the actual state and the empty state, and the lifting speed varies according to the weight.

[0117] The two-level bicycle parking facility 100 (bicycle parking device 1) can be used in outdoor parking lots that are permanently located on sidewalks or in parks, indoor parking lots that are located in apartments or residences, and underground parking lots that are attached to buildings or underground stations.

[0118] This invention is not limited to the embodiments described above and illustrated in the accompanying drawings. For example, the features of the embodiments described above or later can be combined in all possible ways without contradiction. Furthermore, any feature of the embodiments described above or later that is not explicitly stated as essential may be omitted. And, the embodiments described above may be modified as follows.

[0119] In the above-described embodiments, such as Figure 14 as well as Figure 15 As shown, the remote operating device 8 is fixed to the rear end 22B of the lifting frame 22, but it can also be used as follows: Figure 16 As shown, a retainer 29 is provided on the rear end side (e.g., rear end 22B) of the lifting frame 22 in a detachable manner. Figure 16 In this case, the remote operating device 8 can be removed from the holder 29 in the direction of arrow I, and on the other hand, it can be installed relative to the empty holder 29 in the opposite direction to arrow I.

[0120] In the above embodiment, the lifting platform 23 (movable body) is assembled onto the lifting frame 22, but the lifting platform 23 (movable body) and the lifting frame 22 may also be a single component. In this case, the front end of the lifting frame 22 is referred to as the lifting platform 23 (movable body).

[0121] As a variation of the first embodiment, the electric cylinder is similarly fixed to the upper side of the support column with a rod extending downward from the cylinder body. Specifically, the winding transmission mechanism 40 may also be equipped with two fixed pulleys and two movable pulleys on which the rope is wound, or it may be equipped with multiple fixed pulleys and multiple movable pulleys on which the rope is wound. Furthermore, in other variations, the winding transmission mechanism 40 may be equipped with one movable pulley and multiple fixed pulleys. For example, in one variation, the electric cylinder is similarly fixed to the upper side of the support column with a rod extending downward from the cylinder body, and the winding transmission mechanism 40 is equipped with two fixed pulleys and one movable pulley on which the rope 44 is wound. As another example, in another variation, the electric cylinder is similarly fixed to the upper side of the support column with a rod extending downward from the cylinder body, and the winding transmission mechanism 40 is equipped with three fixed pulleys and one movable pulley on which the rope 44 is wound. For example, in a modified version, the electric cylinder is similarly fixed to the upper side of the support column by means of a rod extending downward from the cylinder body, and the winding transmission mechanism 40 is provided with three fixed pulleys and two movable pulleys on which the rope 44 is wound.

[0122] In the bicycle parking device 1 of the above embodiment, the electric cylinder 41 is disposed on the upper part of the support column 21, and the rod 4R extends downward, but it can also be as follows: Figures 17-23 As shown in the second embodiment, the electric cylinder 41 is located at the lower part of the support column 21.

[0123] The following description relates to the second embodiment. Furthermore, functional parts identical to those in the first embodiment are labeled with the same reference numerals, and their descriptions are omitted.

[0124] Figure 17 The bicycle parking device 1 shown in the second embodiment is one of a plurality of bicycle parking devices constituting the upper bicycle parking device 20 of the upper and lower two-level bicycle parking facility 100 of the first embodiment.

[0125] like Figure 17As shown, each bicycle parking device 1 in the second embodiment includes a lifting frame 22 in either a mounted or unmounted state of a bicycle BCL, and an electric drive unit 24 for raising and lowering the lifting platform 23 (movable body) along the support column 21. The electric drive unit 24 includes an electric cylinder 41, a winding transmission mechanism 40, and a control device 9. The electric cylinder 41 is configured with a known structure having a motor 4M, efficiently converting the rotation of the motor 4M into linear motion, causing the rod 4R to extend / retract (advance / retract) from the cylinder body 4H (cylinder housing). The winding transmission mechanism 40 includes: a plurality of fixed pulleys 42 (42A, 42C); a plurality of movable pulleys 43 (43B, 43D) disposed at the front end of the rod 4R; and a rope 44, one end 44a of which is connected to the lifting carriage 23 and extends upward, and is wound around the fixed pulleys 42 (42A, 42C) and movable pulleys 43 (43B, 43D) at its front end, and the other end 44b is fixed to the support column 21. According to the forward and backward movement of the rod 4R, the lifting carriage 23 and the lifting frame 22 are pulled up and down along the support column 21 by the rope 44. They are the same as in the first embodiment.

[0126] Unlike the first embodiment, such as Figure 23 As shown, the electric cylinder 41 is fixed to the lower side of the support column 21 by means of a rod 4R extending upward from the cylinder body 4H. An internal trolley 25 (internal lifting body) is provided at the front end of the rod 4R.

[0127] Thread 44 is used to connect one end 44a (refer to) Figure 18 The cable, connected to the lifting platform 23 (movable body) and fixed at the rope fixing part 23c, extends upwards and is wound around the front of the first fixed pulley 42A (movable body side fixed pulley: see reference) that constitutes the fixed pulley 42. Figure 18 ) and extends downward, with its front portion wound around the first movable pulley 43B constituting the movable pulley 43 and extends upward, with its front portion wound around the second fixed pulley 42C constituting the fixed pulley 42, which is different from the first fixed pulley 42A (see reference). Figure 18 ) and extends downward, with its front portion wound around a second movable pulley 43D, which is different from the first movable pulley 43B, constituting the movable pulley 43, and extends upward, with its front portion at the other end 44b of the rope 44 (refer to Figure 18 The first pulley 42A and the second pulley 42C share a common rotating shaft 21d (here, a bolt: see [reference]).
