Description

  The present invention relates to a load detection device in a type of bicycle parking facility in which each bicycle parking platform that rotates in a circulation path supports a plurality of bicycles in parallel.

  The circulation path of the bicycle parking lot is vertically long, and an endless drive cable is stretched between each large-diameter guide wheel that is pivotally supported at both upper and lower ends, and a plurality of bicycles are attached to the endless drive cable. In a vertically long vertical circulation type bicycle parking facility in which bicycle parking stands supported in parallel are suspended at equal intervals, the bicycle parked at the bicycle entry / exit stop position set at the lower end of the vertical lifting path section. The detection means such as photoelectric sensors arranged on the left and right sides of the front wheel of the bicycle supported by each bicycle support portion corresponding to each bicycle support portion installed in parallel on the wheel base, A stock detection device configured to detect presence or absence is generally known. The occupancy detection device having such a configuration can be used by arranging the detection means of the occupancy detection device at a position where it does not interfere with a bicycle parking lot moving on the circulation path or a bicycle supported thereon. This is because it is easy. However, it is necessary to reduce the height of the bicycle parking facility and install a bicycle parking facility that can be installed between the upper and lower floor slabs of an existing building, for example, under an elevated track, under an elevated road, or at any level of a building. When trying to configure, for example, as described in Patent Document 1, each of the square circulation paths along the vertical plane is formed by extending an endless drive cable on a small-diameter guide wheel pivotally supported at four corners. The bicycle parking equipment configured to rotate the bicycle parking base, lengthen the upper and lower horizontal path portions and shorten the vertical path portions at both ends, for example, to the extent equal to the interval between the bicycle parking stands, A horizontal horizontally long circulation path is configured such that each bicycle parking base rotates.

Japanese Patent Laid-Open No. 55-13370

  As described above, in the bicycle parking facility configured such that each bicycle parking lot rotates along the horizontal oblong circular circulation path, the corner is between the lower horizontal path part and the vertical path part on one side. A stop position for bicycle entry / exit is set, and the front wheel of the bicycle supported on the bicycle stand that stops at this bicycle entry / exit stop position is on the side of the bicycle parking stand adjacent to the lower horizontal path section side. Will be located. Therefore, the presence or absence of a bicycle on each of the bicycle support parts arranged in parallel on the bicycle parking lot stopped at the bicycle entry / exit stop position is used in the conventional vertically long vertical circulation type bicycle parking equipment. When detecting by the detection device, each detection means such as a photoelectric sensor constituting the stock detection device is arranged in the lower horizontal path, and the bicycle parking base moves along the lower horizontal path portion. Can not be implemented. Of course, it is conceivable to detect the presence of goods using detection means arranged on the floor surface side. However, when a photoelectric sensor is used for the detection means, the light projecting / receiving part of the photoelectric sensor faces upward so that it is easily contaminated. In addition, high-precision detection is difficult.

  The present invention proposes a parking facility occupancy detection device capable of solving the above-described conventional problems, and the parking facility occupancy detection device according to the present invention will be described later. In order to facilitate understanding of the relationship with the embodiment, when the reference numerals used in the description of the embodiment are shown in parentheses, the bicycle parking platform (1) that moves the circulation path along the vertical plane is shown. , Equipped with a plurality of bicycle support bases (14A-15B) arranged in parallel in the horizontal direction perpendicular to the moving direction, and the front wheel (Cf) of the bicycle (C) is fitted to each bicycle support base (14A-15B) In the bicycle parking facility provided with the front wheel support portion (16a), the front wheel support portion (16a) of each bicycle support base (14A to 15B) is pivotally supported around the horizontal support shaft (44). And a movable member (32, 33) having a front wheel contact portion (36, 38) and a detected portion (37, 40) is provided, and the movable member (32, 33) is connected to the front wheel contact portion. (36,38) is the front wheel An urging means (35) for urging and holding in a standby posture projecting into the holding portion (16a) is provided, and the detected portions (37, 40) of each movable member (32, 33) are provided with one bicycle parking. All the movable members (32, 33) on the base (1) are pushed by the bicycle front wheel (Cf) whose front wheel contact portion (36, 38) is fitted in the front wheel support portion (16a). When switched to the acting posture against the urging force of the urging means (35), when the bicycle parking pedestal (1) is viewed from the lateral side of the circulation path, The detectors (37, 40) are arranged so that they do not overlap each other and can be seen individually, and on the lateral sides in the circulation path, each movable member (1) of the bicycle parking stand (1) stopped at a fixed position ( Corresponding to (32, 33), the detection means (46-49) for individually detecting the detected parts (37, 40) of the movable member (32, 33) in the acting posture is provided. ing.

  According to the configuration of the present invention, the presence / absence of a bicycle on each bicycle support stand in parallel on the bicycle stand that is stopped at a fixed position on the circulation route is determined by the side of the circulation route of the bicycle stand for each bicycle support stand. It can detect reliably by the detection means (for example, photoelectric sensor) corresponding to each provided bicycle support stand. Therefore, it is a bicycle parking facility configured such that each bicycle parking lot rotates in a horizontal horizontally long circular circulation path as described above, and its lower horizontal path part and one side vertical path part, A stop position for bicycle entry / exit is set at the corner between the front and the front wheels of the bicycle supported on the bicycle stand that stops at this bicycle entry / exit stop position. Even in the situation where the wheelchair is located, the presence or absence of a bicycle on each bicycle support stand in parallel on the bicycle parking lot stopped at the bicycle entry / exit stop position is reliably detected by a detection means such as a photoelectric sensor. I can do it. Of course, the detection means such as photoelectric sensors are not located on the bicycle parking platform, but on the side of the circulation path of the parking bicycle, so one set of detection means is used regardless of the number of bicycle parking lots. The configuration of the wiring system is much simpler than that provided on a moving bicycle parking lot. In addition, when a photoelectric sensor is used as the detection means, the risk of contamination of the light emitting / receiving portion of the photoelectric sensor is extremely reduced compared to the case where the photoelectric sensor is disposed upward on the floor surface side, so that there is always high accuracy. Load detection can be performed.

When carrying out the present invention, specifically, as described in claim 2, as the bicycle support base (14A to 15B), a plurality of lower bicycle supports having a low front wheel support portion (16a) are provided. A base (14A, 14B) and a plurality of high-level bicycle supporters (15A, 15B) with a high front wheel support (16a) are installed in parallel, and the front wheel support (14A, 14B) of each low-level bicycle support (14A, 14B) The movable members (32, 33) having different positions of the detected parts (37, 40) are attached to 16a), and the front wheel support part (16a) of each high-level bicycle support base (15A, 15B) is provided with a lower position. The movable member (32, 33), which has the same position as the movable member (32, 33) attached to the bicycle support base (14A, 14B) and whose position of the detected part (37, 40) is different , is attached to all bicycles. When the movable members (32, 33) of the support bases (14A to 15B) are in the working posture as viewed from the lateral side of the circulation path, the detected parts (all of the movable members (32, 33)) 37, 40) do not overlap each other and can be seen individually It can be configured to.

  According to this configuration, the number of the movable members attached to each bicycle support base can be halved with respect to the number of bicycle support bases installed in parallel on one bicycle parking stand, and the cost can be reduced. I can do it.

  In addition, as described in claim 3, the bicycle support base (14A to 15B) is constituted by an upper open groove-shaped rail member (16) into which a wheel of the bicycle (C) is movably fitted. The front wheel support portion (16a) that is lowered by one step is provided at the front end, and the movable member (32, 33) is fitted inside the rail member (16), and its intermediate position in the length direction is A horizontal support shaft (44) is supported at the rear end corner of the front wheel support section (16a) so that the seesaw can move freely, and the front end bottom plate section (32a, 32a, 33) on the front wheel support section (16a) side of the movable member (32, 33). 33a) is configured as the front wheel abutting portion (36, 38), and the detected portion (32b, 33b) is connected to the detected portion by the side plate portion (32b, 33b) connected upward from the rear end portion of the movable member (32, 33). 37, 40), and when the movable member (32, 33) is in the working posture, the detected part (37, 40) is a bicycle support (14A-15B) and a bicycle front wheel (Cf). It can be configured to protrude into the corner space between That.

  According to this configuration, when the bicycle is not placed on the bicycle support base, almost all of the movable member from the front wheel abutting portion on the front end side to the detected portion on the rear end side constitutes the bicycle support base. When the bicycle is placed on the bicycle support stand, the detected portion of the movable member protrudes into the space between the bicycle support stand and the bicycle. In other words, the detected portion of the movable member can be prevented from protruding from the entire outline including the bicycle support base and the bicycle on the bicycle support base. Therefore, the movable member is compared with a configuration in which the movable member is pivotally supported on the front end side of the front wheel support portion of the bicycle support base, and the detected portion projects obliquely forward and upward from the front end of the bicycle support stand. Not only does the entire bicycle support including the size of the bicycle support base not only increase in size, but also reduces the risk of other objects colliding with the movable member and causing damage.

  In the case of adopting the above-described configuration, as described in claim 4, the movable member (32, 33) is configured by a groove member that is open on the upper side through which the bicycle front wheel (Cf) can be fitted, and its bottom plate portion. (32a, 33a) A bearing member (34) projecting downward from the center in the length direction is an opening provided on the bottom surface of the rear end corner of the front wheel support (16a) of the rail member (16). Projecting downward from the portion (41) and pivotally supported by a horizontal support shaft (44) on a bearing plate (43) attached to the outside of the rail member (16), and the biasing means includes the movable member ( 32, 33) is composed of a weight (35) attached to the lower side of the rear end of the bottom plate portion (32b, 33b), and the weight (35) is vertically arranged on the bottom plate portion of the rail member (16). An opening (42) that can be freely fitted and removed can be provided.

  According to this configuration, the movable member can be made of a thin plate and can have sufficient bending strength, and the structure is simple and has the expected effect as compared with the case where a spring is used as the biasing means. Can always be performed reliably. Further, the bottom plate portion of the rail member can be used as it is as a stopper for determining the standby posture of the movable member, and the structure is simplified compared to the case where a stopper made of another member must be attached.

  Furthermore, as described in claim 5, the side plate portion (33b) constituting the detected portion (40) of the movable member (33) has a detected portion of the movable member (32) of another bicycle support base. A notch recess (39) can be formed at a location overlapping (37) in a side view. According to this configuration, the position of the detected portion of the movable member attached to a plurality of bicycle support tables installed at the same height is different in the length direction of the movable member. Compared with a configuration in which the position of the detected portion is changed vertically and vertically to the vertical direction, the movable member in the standby posture is housed inside the rail member, and the detected portion of the movable member in the working posture is There is almost no influence in the point which fits in the space between the said rail member and the bicycle on it, It is convenient to implement the structure of the said Claim 3 and 4.

It is attached. As shown in FIG. 9, the detection means 46 is configured so that the movable members 32 and 33 attached to the bicycle support bases 14 </ b> A to 15 </ b> B of the bicycle parking stand 1 stopped at the bicycle entry / exit stop position A are in the acting posture. At one time, four sets of transmission type photoelectric sensors 46 to 49 provided corresponding to the bicycle support bases 14A to 15B so that the optical axes are blocked by the detected portions 37 and 40 of the movable members 32 and 33, respectively. It is composed of Each photoelectric sensor 46-49 consists of the combination of light projectors 46a-49a and light receivers 46b-49b, and these light projectors 46a-49a and light receivers 46b-49b are fixed wall frames on the left and right sides of the bicycle entry / exit stop position A. The first movable member 32 and the second movable member 33 to be detected are attached to the lower bicycle support bases 14A and 14B (or the higher bicycle support bases 15A and 15B) at the same height. Since the optical axes of the two sets of photoelectric sensors 46 and 47 (or 48 and 49) for detecting the sections 37 and 40 are very close to each other, as shown in FIG. It is desirable to reverse the placement of the vessel.

According to the stock detection device having the above-described configuration, when the bicycle parking platform 1 stops at the bicycle entry / exit stop position A, the photoelectric sensors 46 to 49 receive light by switching the photoelectric sensors 46 to 49 to ON. The presence / absence of the bicycle C for each of the bicycle support bases 14A to 15B, that is, the loaded state can be detected from the ON and OFF states of the devices 46b to 49b. That is, among the bicycle support bases 14A to 15B, the movable member 32 or 33 of the bicycle support base on which the bicycle C is supported is switched to the action posture as described above, and the detected portion 37 or 40 is Since the optical axes of the photoelectric sensors 46 to 49 corresponding to the movable member 32 or 33 of the bicycle support base on which the bicycle C is supported are cut off and the light receivers 46b to 49b are in the OFF state, the light receivers 46b to 49b. From the OFF state, it is determined that the bicycle support base is in stock. Conversely, among the bicycle support bases 14A to 15B, the movable member 32 or 33 of the empty bicycle support base where the bicycle C is not supported is Since the detected position 37 or 40 is stored in the rail member 16 as described above, the photoelectric sensor corresponding to the movable member 32 or 33 of the empty bicycle support base is used. Since the optical axes of the sensors 46 to 49 are not cut off and are incident on the light receivers 46b to 49b, and the light receivers 46b to 49b are turned on, the bicycle support base is moved from the ON state of the light receivers 46b to 49b. It can be determined that the state is empty.

  As shown in FIG. 9, when the second movable member 33 attached to the lower bicycle support bases 14A and 14B or the higher bicycle support bases 15A and 15B at the same height is in the acting posture, the first movable member The optical axes of the photoelectric sensors 46 and 48 for detecting 32 detected portions 37 pass through the notch recess 39 provided in the side plate portion 33 b of the second movable member 33, and the side plate portion of the second movable member 33. 33b is not interrupted, the photoelectric sensors 46 and 48 for detecting the detected portion 37 of the first movable member 32 are used to determine whether or not the first movable member 32 is in the acting posture, that is, the first movable member. It is possible to reliably detect whether the bicycle support base 14A or 15A provided with 32 is in stock.

  In addition, although the four bicycle support bases 14A-15B were installed in parallel on the bicycle parking lot 1, the number of bicycle support bases is not limited to these four. Further, the structure of each of the bicycle support bases 14A to 15B is not limited to that of the above embodiment. Further, as the detecting means, a transmissive photoelectric sensor in which a projector and a light receiver are arranged to face each other is used, but the detected portions 37 and 40 of the movable members 32 and 33 are used as light reflecting surfaces. It is also possible to use a reflective photoelectric sensor.

  The load detection device for a multi-story bicycle parking facility according to the present invention is particularly suitable for installation in a slab space of an existing building, for example, a space under an elevated track, a space under an elevated road, or an arbitrary hierarchical space of a building. It can be used as a means for detecting the presence or absence of a bicycle for each bicycle support stand installed in parallel on a bicycle parking stand in a low-rise type three-dimensional bicycle parking facility.
