Description

  The present invention relates to a pallet lock device and an elevator parking device. More specifically, the present invention relates to a pallet locking device for restraining a pallet for mounting on a vehicle on a parking shelf of the parking device, and an elevator parking device provided with the pallet locking device.

  As shown in FIG. 1, an elevator parking apparatus 1 generally has a plurality of upper and lower parking shelves 4 that store vehicles M along a hoistway 3 of an elevator 2 for transporting vehicles. The elevator parking apparatus 1 is often incorporated in a tower-shaped steel structure (also referred to as a parking tower) 1a that is erected on the outdoor ground or in a building void. And the entrance / exit 5 is provided in the ground which is the lowest part of the hoistway 3 generally. The elevator 2 mounts a pallet 6 mounted on the vehicle, moves up and down in the hoistway 3 by a wire rope 7 or the like, and parks with the elevator 2 by a pallet transfer device (for example, reference numeral 10 in FIG. 2) installed in the elevator 2. The pallet 6 is transferred to and from the shelf 4. The wire rope 7 is driven up and down by a lift driving device 8 installed on the top floor, and a counterweight 9 is connected to the other end.

  Each parking shelf 4 of the elevator type parking apparatus 1 is equipped with a pallet lock mechanism (not shown). This pallet locking mechanism is for preventing the pallet 6 stored in the parking shelf 4 from moving horizontally due to vibrations caused by driving of the parking device 1 or shaking of the earthquake and starting to slide toward the hoistway 3 side.

  Conventional pallet locking devices include, for example, a pallet drop prevention device disclosed in Patent Literature 1, a pallet locking mechanism disclosed in Patent Literature 2, a tray locking device disclosed in Patent Literature 3, and Patent Literature 4 The disclosed pallet locking device is known.

  The pallet drop prevention device disclosed in Patent Document 1 is installed on the parking shelf. This device is provided with a fixed fixing member that contacts the pallet wheel on the rear side so that the pallet does not move horizontally on the parking shelf, and a movable member that can contact the pallet and release the contact on the hoistway side. A member of a formula (movable member) is provided. The pallet is prevented from moving in the horizontal direction (transfer direction between the elevator and the parking rack) by the fixed member and the movable member. The movable member is urged so as to always engage the pallet by a spring. When the pallet is moved, the movable member is moved by a separate means to release the pallet constraint.

  The pallet locking mechanism disclosed in Patent Document 2 is also installed on the parking shelf. This mechanism has a fixed stopper block that contacts the wheel of the pallet on the back side so that the pallet does not move horizontally on the parking shelf, advances to the hoistway side, contacts the pallet and retreats. A movable stopper rod that can be released from contact is provided. The pallet is prevented from moving in the horizontal direction by the stopper block and the stopper rod. The stopper rod is advanced and retracted by a positioning rod and a swing arm.

  The tray lock device disclosed in Patent Document 3 is also installed on the parking shelf. This device is provided with a fixing hook that engages with a back stopper pin provided on the pallet on the back side so that the pallet does not move horizontally on the parking shelf, and a hoistway side stopper provided on the pallet on the hoistway side. A movable hook that swings so as to engage and disengage from the pin is provided. The pallet is engaged by a fixed hook and a movable hook to prevent horizontal movement. The movable hook is biased by a spring to a position where the movable hook can engage with the hoistway side stopper pin of the pallet. When moving the pallet, the movable hook is swung by a lock release device to release the restraint of the pallet.

  In the conventional technology described above, maintenance is required because the movable member, the movable stopper rod, and the movable hook that are engaged to restrain the pallet on each parking shelf are movable. In addition, a mechanism for swinging the movable hook or the like is required for releasing the engagement, which makes the structure complicated and increases the manufacturing cost and the maintenance cost.

  Moreover, although the parking tower 1a has an earthquake resistant structure, in recent years, there has been a tendency to increase the number of buildings to improve vehicle storage efficiency. As shown by a two-dot chain line in FIG. In the case of a parking tower installed in the upper floor), it can be considered that the upper layer shakes largely like a bow. In such a case, the movable mechanism may be damaged or malfunction. Moreover, in order to avoid such a situation, it is necessary to give sufficient strength to the movable mechanism, and the entire apparatus becomes large.

  On the other hand, the pallet locking device disclosed in Patent Document 4 according to the application of the present applicant is to restrain the pallet 62 for mounting on the vehicle M on the parking rack (rail) 61, as shown in FIG. A recess 64 formed in the upper surface of the hoistway side end of the parking shelf 61 for dropping the wheel (transverse roller) 63 of the pallet 62, and a stopper projecting slightly on the side of the hoistway side from the recess 64 And a member 65. This stopper member 65 exerts an action of preventing the pallet 62 from moving in the horizontal direction by approaching and abutting against an abutting portion 66 that is also used as a wheel support portion. In this pallet lock device, each parking shelf is not equipped with any operation mechanism, and it has a simple structure and is hardly damaged.

However, the lower surface of the pallet reinforcing groove member 67 that is fixed to the lower surface of the pallet and is configured integrally with the contact portion 66 is formed in a straight line between the left and right wheels 63 over substantially the entire length. Therefore, if the pallet 62 is lifted by shaking such as an earthquake and the wheels or the lower surface of the end of the groove member 67 rides on the stopper member 65, the pallet 62 may slide out to the hoistway side due to further shaking (2 in FIG. 13). (See dotted line).
Japanese Patent Laid-Open No. 8-319729 JP-A-8-13841 JP-A-10-196149 JP 2004-52430 A

  The present invention has been made to solve such a problem, and is a pallet locking device that restrains a pallet on a parking shelf with a simple configuration without using a movable member in each parking shelf. An object of the present invention is to provide a pallet lifting device that can avoid a situation where the vehicle slides out of the parking shelf, and an elevator parking device that includes the pallet lifting device.

The pallet locking device of the present invention is
A pallet, which is installed in a vehicle wheel disposed on the lower surface, and an elevator for lifting the pallet, and a plurality of stages arranged vertically along the elevator shaft, a parking shelf for placing the pallet An elevator parking device configured to roll the wheel on the parking shelf in the width direction of the pallet, and a pallet locking device for restraining the pallet on the parking shelf,
A stopper formed sideways from the parking shelf;
A contact member formed on the pallet so as to contact the stopper,
This contact member is
A first contact portion formed downward from the pallet so that the pallet can contact the stopper in the horizontal direction when the pallet is about to move in the hoistway direction at the position where the pallet is placed on the parking shelf. When,
In the pallet, on the side opposite to the hoistway of the first abutting portion, when the wheel moves downward from the hoistway side end of the parking shelf, it faces downward so that it can abut against the stopper in the horizontal direction. And the formed second contact portion.

  With this configuration, when the pallet is on the parking shelf, the first contact portion of the pallet contacts the stopper of the parking shelf, thereby preventing the pallet from sliding out of the parking shelf. And, for example, even if the first abutting part gets over the stopper and the pallet moves to the hoistway side due to an earthquake accompanied by severe pitching, etc., the second abutting part of the pallet abuts the stopper in the horizontal direction. Further movement of the pallet to the hoistway side is prevented. Furthermore, since the stopper and the first and second contact portions are fixed rather than movable, they are strong and easy to maintain.

  Here, the side opposite to the hoistway in the pallet mentioned above is closer to the center than at least one of the left and right ends of the pallet when the relative relationship with the hoistway is ignored and the pallet is focused. . Further, the hoistway side in the pallet is near at least one of the left and right ends near the center of the pallet.

  As described above, the first abutment portion ensures that the stopper abuts against the second abutment portion when the first abutment portion gets over the stopper due to severe shaking and the pallet moves to the hoistway side. A recess that opens downward may be formed between the first contact portion and the second contact portion so that the stopper can be fitted upward. Moreover, if the recess is formed in this way, it is not necessary to increase the vertical dimension of the contact member.

  A main body in which the first abutting portion is formed on the hoistway side of the abutting member, and a hook member protruding so as to bend downward from the anti-hoistway side end of the main body toward the anti-hoistway side It is also possible to configure the recess from the hook member and the end portion on the side opposite to the hoistway of the main body, and to configure the second contact portion on the inside of the hook member.

  In order to prevent the stopper from being easily detached by vibration or the like once it is engaged with the second contact portion, an engagement space for engaging the stopper is formed in the upper rear portion in the recess, and this engagement space A surface as a second contact portion can be formed on the side opposite to the hoistway, a lateral locking surface can be formed on the hoistway side of the engagement space, and a lower locking surface can also be formed below the engagement space. For example, an L-shaped notch may be formed in the recess toward the side opposite to the hoistway. And what is necessary is just to comprise the surface by the side of the uppermost anti-hoistway of this notch as a 2nd contact part.

  Further, a beam member for reinforcement is fixed to the lower surface of the pallet, the hoistway side end portion of the beam member is also used as a contact member, and the first contact portion and the second contact portion are formed in this portion. You can also.

A connecting member configured to connect the elevator and the parking shelf in a detachable manner and allow the pallet to move on the elevator or the parking shelf is disposed in the elevator or the parking shelf,
The connecting member parks the pallet so that the abutting portion is positioned above the stopper when the connecting member is bridged between the parking shelf and the elevator and when the pallet moves on the connecting member. It can be configured to push upward from the shelf.

  According to such a configuration, the same action as the above-described invention is achieved in that the pallet is prevented from sliding out of the parking rack. When the connecting member connects the parking shelf and the elevator, the pallet is pushed up and the contact portion exceeds the stopper, so that the lock to the parking shelf is released and the elevator and the parking shelf It is possible to easily deliver pallets.

The elevator parking apparatus of the present invention is
A parking shelf for mounting a pallet for mounting on a vehicle;
An elevator for raising and lowering this pallet;
Moving means for moving the pallet between the elevator and the parking rack;
A pallet locking device for locking the pallet on the parking shelf,
This pallet locking device is composed of any one of the pallet locking devices described above.

  According to the present invention, when the pallet is placed on the parking shelf, the first contact portion of the pallet contacts the stopper of the parking shelf, thereby preventing the pallet from sliding out of the parking shelf. Further, even if the pallet is lifted and slides toward the hoistway due to an earthquake or the like, the pallet is prevented from sliding out of the parking shelf by the second contact portion of the pallet coming into contact with the stopper of the parking shelf. Since the pallet or the like can be restored when such a situation is reached, further pallet sliding is prevented. Moreover, in the present invention, it is not necessary to provide any operating mechanism for each parking shelf.

  DESCRIPTION OF EMBODIMENTS Embodiments of a pallet locking device and an elevator parking device of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 illustrates an elevator parking apparatus (hereinafter simply referred to as a parking apparatus) to which the pallet locking apparatus of the present invention can be applied. FIG. 2 is a sectional view taken along the line II-II and shows a parking floor of the parking apparatus.

  As described above, in the parking apparatus 1, the parking racks 4 on the upper and lower floors are arranged along the hoistway 3 of the elevator 2. The parking shelf 4 is composed of rail members extending in the width direction at positions corresponding to the front end and the rear end of the pallet 6, and is fixed to a shelf column 4a standing on the floor. The parking rack 4 may be inclined so as to face the hoistway 3 slightly upward in order to suppress the horizontal movement of the pallet 6 to the hoistway side. The elevator 2 moves up and down between the parking racks 4 on both sides, moves to the designated floor of the parking rack 4, pulls out the empty pallet 6 or the pallet 6 on which the vehicle M is mounted, and enters and exits the parking rack 4. Transport to the floor. A pallet transfer device 10 to be described later for pulling the pallet 6 from the parking shelf 4 and returning it to the parking shelf 4 is disposed in the center of the elevator 2 (FIG. 2).

  Wheels (also referred to as transverse rollers) 30 are disposed on the lower surface of the pallet 6. The wheels 30 roll on the rails 2 a installed in the width direction near the front and rear ends of the elevator 2 and on the parking rack 4. By doing so, the pallet 6 can move between the elevator 2 and the parking rack 4. As shown in FIG. 2, the pallet transfer device 10 includes a first arm 11a whose base end portion is pivotally supported in a horizontal plane at a central portion of the elevator 2, and a distal end portion of the first arm 11a. And a second arm 11b having a base connected rotatably in a horizontal plane.

  An operation for returning the pallet 6 to the parking shelf 4 and a receiving operation (transverse operation) by the pallet transfer device 10 will be briefly described. The first arm 11a is turned in a predetermined direction so that the angle formed by the two arms 11a and 11b does not change, and the engagement roller 12 at the tip of the second arm 11b is engaged with the engagement groove 13 on the lower surface of the pallet 6. Next, the arms 11 a and 11 b are turned so that the engaging roller 12 moves in the width direction of the pallet 6 in the engaged state. In this way, the pallet 6 is traversed by pushing and pulling toward the parking rack 4 or toward the elevator 2. When the pallet 6 is in a predetermined position on either the elevator 2 or the parking rack 4, the predetermined arms 11 a and 11 b are turned to disengage the engagement roller 12 from the engagement groove 13 of the pallet 6. The driving of the arms 11a and 11b is detailed in Japanese Patent Application No. 2001-239116 filed by the present applicant.

  As the pallet transfer device, a known device such as a chain carrier type disclosed in Japanese Patent No. 598708 and a crank arm type disclosed in Japanese Patent Publication No. 7-33734 can be adopted. However, the pallet transfer device 10 having a pallet turning function is preferable.

  When the pallet 6 is transferred between the elevator 2 and the parking shelf 4, the elevator 2 is preferably positioned so that the upper surface of the elevator 2 and the upper surface of the parking shelf 4 are substantially in the same horizontal plane. For this purpose, as shown in FIG. 2, level adjusters 14 are arranged at the four corners of the elevator 2 to fix the elevator 2 to the parking rack 4 and perform vertical positioning.

  As shown in FIG. 3, the level adjusting device 14 includes a connecting member 15 disposed in the elevator 2 and a positioning roller 16 disposed in the parking rack 4. The connecting member 15 extends from the elevator 2 to the parking shelf 4 when the elevator 2 reaches the designated parking shelf 4, and engages with a positioning roller 16 to connect the two and 4. When connected by the level adjusting device 14, the upper surfaces of both 2 and 4 are at the same level, and the pallet transfer device 10 can easily transfer the pallet 6 from one to the other. As will be described later, the connecting member 15 also functions as a locking release mechanism in the pallet lock devices (hereinafter simply referred to as lock devices) 17 and 18.

  Here, the lock device may include an elevator lock 18 for fixing the pallet 6 on the elevator 2 in addition to the shelf lock 17 for fixing the pallet 6 on the parking shelf 4. Both of the locks 17 and 18 are provided to prevent the placed pallet 6 from slipping on the elevator 2 or the parking shelf 4 due to vibrations or the like and inadvertently moving. is there. Since the elevator lock 18 has the same configuration as the first lock disclosed in Patent Document 4 according to the above-mentioned application of the present applicant, it will be briefly described later.

  The effect | action of the lock 17 for shelves in the parking shelf 4 is demonstrated referring FIGS. The shelf lock 17 includes a stopper 19 projecting from the side surface of the parking shelf 4, a contact member 20 projecting downward from the pallet 6 so as to be able to contact the stopper 19 in the horizontal direction, It is comprised from the recess 21 formed in the upper surface of the parking shelf 4. As shown in FIG.

  The contact member 20 in the present embodiment is formed by using an end portion of the groove member 22 as a reinforcing beam that is fixed to the lower surface of the pallet 6 and extends in the width direction of the pallet. As shown in FIG. 4, the contact member 20 is in contact with the stopper 19 in the horizontal direction on the first contact portion 23 formed on the most hoistway side and on the side opposite to the hoistway of the first contact portion 23. A second contact portion 24 formed downward is formed so as to be obtained. Both of the contact portions 23 and 24 are substantially vertical surfaces so that they can contact the stopper 19 in the horizontal direction. Therefore, when the abutting portions 23 and 24 abut against the stopper 19, no upward reaction force is generated. That is, since the component of the force which pushes up the pallet 6 is not generated, the contact parts 23 and 24 do not jump over the stopper 19 and the pallet 6 does not go out to the hoistway 3. In the present embodiment, the hoistway side end surface of the groove member 22 is used as the first contact portion 23. The second contact portion 24 is formed as a vertical surface on the side opposite to the hoistway of the trapezoidal cutout portion 25 in which the lower side of the groove member 22 is cut upward. The reason why the notch 25 has a trapezoidal shape is that the lower end 25a of the lower opening of the lower opening is cut obliquely so that the stopper 19 can easily enter. The upper end side 25 b of the notch 25 is made to coincide with the lower end side of the channel member 22. Therefore, the contact member 20 has two pieces 29 protruding downward from the lower side of the groove member 22 in order to form the first contact portion 23 and the second contact portion 24.

  In the recess 21, wheels 30 on the hoistway side of the pallet 6 when placed at a predetermined position on the parking shelf 4 are fitted (see FIG. 4). From this state, it cannot easily move horizontally. Moreover, since the first contact portion 23 of the pallet 6 at this position faces the stopper 19, the pallet 6 tries to move horizontally to the hoistway side by some action, and the wheel 30 comes out of the recess 21. Even if it does so, the 1st contact part 23 contact | abuts to the stopper 19, and a horizontal movement is blocked | prevented. This is because the positional relationship between the recess 21 and the stopper 19 and the positional relationship between the wheel 30 and the first abutting portion 23 are such that the wheel 30 in the recess 21 contacts the hoistway side end of the recess 21. This is because the stopper 19 and the first contact portion 23 are set to contact each other. Further, the positional relationship between the stopper 19 and the first contact portion 23 is as follows. When the wheel 30 of the pallet 6 is stuck in the recess 21, the first contact portion 23 is in a position where it can contact the stopper 19 in the horizontal direction (contact position). That is, the first contact portion 23 faces the stopper 19 in the horizontal direction. When the wheel 30 comes out of the recess 21 and reaches the upper surface of the parking shelf 4, the contact member 20 is located above the stopper 19 and cannot be contacted (non-contact position). In order to achieve such an effect, as shown in FIG. 4, the depth h of the recess 21 is made larger than the vertical dimension D of the stopper 19 and the first contact portion 23.

  As shown in FIG. 4, the lower end 23 a of the first abutting portion 23 and the lower end 24 a of the second abutting portion 24 are defined by the lower side of the abutting member 20. Yes. Therefore, when the first contact portion 23 is in the contact position, it can be said that the second contact portion 24 is also in the contact position. Further, when the first contact portion 23 is in the non-contact position, it can be said that the second contact portion 24 is also in the non-contact position. Of course, the lower end 23a of the first contact portion 23 and the lower end 24a of the second contact portion 24 may be at different height positions. The positional relationship between the connecting member 15 and the stopper 19 must be set so that the lower end 23a, 24a of any contact portion is positioned above the stopper 19 (non-contact position) when pushed up.

  The wheel 30 will be described with reference to FIGS. 5 and 9. FIG. 5 is a view taken along the line VV in FIG. 4, and is a view of the parking rack 4 viewed from the right to the left. 9 is a cross-sectional view taken along line IX-IX in FIG. As shown in the drawing, the wheel 30 has a coaxial small-diameter portion 30a, a large-diameter portion 30b, and a flange portion 30c that are integrally formed in order from the inside of the pallet 6. The large-diameter portion 30b is a portion that rolls on the parking rack (rail member) 4 and on the rail 2a of the elevator 2, and the width thereof is substantially the same as the width of the rails 2a and 4. The flange 30c can abut against the side surfaces of the rails 2a and 4 and has an effect of preventing the wheels 30 from coming off the rails 2a and 4. The small diameter portion 30a is a portion that rolls on the connecting member 15 as will be described later.

  As described above, the second contact portion 24 is formed on the pallet 6. Therefore, even if the first abutting portion 23 gets over the stopper 19 and the pallet 6 moves to the hoistway side due to an earthquake or the like with severe pitching, the second abutting portion 24 is moved horizontally to the stopper 19. It abuts (see FIG. 6), and further movement of the pallet 6 toward the hoistway is prevented. As is clear from FIG. 6, the second contact portion 24 is formed on the contact member 20 at a position where the wheel 30 is detached from the hoistway side end of the parking rack 4 as the pallet 6 moves to the hoistway 3 side. It is a position where it can come into contact with the stopper 19 when it moves downward.

  However, the lower end 24 a of the second contact portion 24 may be positioned further below the lower end 23 a of the first contact portion 23. In such a case, when the pallet 6 has moved to the hoistway 3 side by slightly changing the position of the second abutment portion 24 to the hoistway side so as to approach the first contact portion 23, It is also possible for the second contact portion 24 to come into contact with the stopper 19 and prevent horizontal movement before the wheels 30 are disengaged from the hoistway side end of the parking shelf 4.

  Since the vibration that causes the pallet to move is due to a strong earthquake or the like, after such a situation has occurred, the parking apparatus 1 itself is generally inspected and restored. Therefore, even when the second contact portion 24 is engaged with the stopper 19, the original state is restored and further pallet sliding is prevented.

  With reference to FIG. 3, a shelf unlocking mechanism for unlocking the pallet 6 and the parking shelf 4 will be described. As described above, the connecting member 15 provided in the elevator 2 is the shelf unlocking mechanism. The positioning roller 16 is attached in the vicinity of the end of the parking shelf 4 on the hoistway side. A positioning opening 26 for positioning that can be engaged with the positioning roller 16 when the connecting member 15 advances is formed at the front end of the connecting member 15 on the shelf side. The width of the rear side of the positioning opening 26 is substantially the same as the outer diameter of the positioning roller 16, but the tip opening side of the positioning opening 26 is inclined so as to open. Even if there is a level difference between the upper surface of the elevator 2 and the upper surface of the parking shelf 4 due to the positioning opening 26 having the tip inclined and opened, as long as it is within the open width of the tip of the positioning opening 26, the connecting member 15. When the positioning roller 16 is engaged in the back of the positioning opening 26, that is, when the elevator 2 and the parking rack 4 are connected by the connecting member 15, the levels of the upper surface of the elevator 2 and the upper surface of the parking rack 4 coincide. Have been to.

  The moving surface 15b of the connecting member 15 is slightly above the upper surface of the rail 2a of the elevator 2, that is, the difference between the radius of the small diameter portion 30a of the wheel 30 of the pallet 6 and the radius of the large diameter portion 30b (shown in FIG. 5). It is arranged so as to be positioned upward by the dimension F). As described with reference to FIGS. 5 and 9, the small-diameter portion 30a of the wheel 30 rides on the moving surface 15b of the connecting member 15, and the large-diameter portion 30b is placed on the rail 2a of the elevator 2 or parked. This is because it rides on the shelf 4.

  However, the wheel 30 may have the same diameter over the entire width except for the flange 30c without dividing the diameter of the wheel 30 into a small diameter and a large diameter. In this case, the moving surface 15b of the connecting member 15 is made to coincide with the upper surface of the rail 2a of the elevator 2.

  Further, a downwardly inclined portion 15 a is formed on the upper surface of the shelf-side tip of the connecting member 15. Therefore, as shown in FIG. 3, when the connecting member 15 is engaged with the positioning roller 16, the inclined portion 15 a enters under the wheel 30 and pushes up the wheel 30. As a result, the pallet 6 is pushed up to a position where the lower end of the contact member 20 is above the upper end of the stopper 19. That is, since the lower end positions 23a and 24b of the first and second contact portions 23 and 24 are the same, the pallet 6 can contact both the stopper 19 and the first and second contact portions 23 and 24. Pushed up to a non-contact position. And it will be in the state which can move the pallet 6 from the parking shelf 4 to the elevator 2 through the movement surface 15b of the connection member 15 by the pallet transfer apparatus 10. FIG. This is the unlocking of the shelf lock 17.

  As described above, when the lower end 23a of the first contact portion 23 and the lower end 24a of the second contact portion 24 are at different height positions, the connecting member 15 pushes the pallet 6 up. In addition, the dimensions must be determined so that the lower ends 23a, 24a of any of the contact portions are in the non-contact position above the stopper 19.

  The elevator lock 18 and the connecting member 15 as the elevator lock release mechanism will be described with reference to FIGS. When the pallet 6 traverses, the wheel 30 rolls on the rail 2a of the elevator 2, the moving surface 15b on the connecting member 15, and the parking rack 4. 7 and 8 also show the contact member 20, the first contact portion 23, and the second contact portion 24 on the left side of the pallet 6.

  Pallet locking members (hereinafter simply referred to as locking members) 27 are pivotally supported by pins 28 at the left and right front and rear ends of the elevator 2 (this portion is also referred to as a pivot portion 28). However, only the left front end of the elevator is shown in the figure. The locking member 27 is pivotally supported at a substantially intermediate portion in the thickness direction of the beam constituting the elevator 2. The elevator lock 18 is composed of the locking member 27 and a drive projection 39 described later. The locking member 27 has an upper surface curved in a concave shape. Of course, the concave shape may be curved in a substantially J shape or L shape, or may be curved in an arc shape. The vicinity of the front end of the locking member 27 on the parking shelf side, that is, the portion where the upper surface rises constitutes a locking portion 31 to which the wheel 30 is locked. The position where the locking portion 31 is locked to the wheel 30 is the operating position for the locking member 27 and the locking portion 31. In order to more securely lock the locking portion 31 to the wheel 30, the upper end of the locking portion 31 is higher than the center position of the wheel 30 as shown in the figure in the shape of the locking portion 31 at the operating position. Good.

  Further, the vicinity of the end portion on the opposite side of the locking portion 31 is a base portion 32. The upper surface is linearly formed from the end portion of the base portion 32 to the locking portion 31 via the pivot portion 28. The weight of the locking member 27 on the side of the locking part 31 with respect to the pivot part 28 is set to be larger than the weight on the side of the base part 32 with respect to the pivot part 28. Therefore, unless the locking member 27 is supported by an external force, the locking member 27 rotates to lower the locking portion 31 side (FIG. 8), and becomes a non-operating position where the locking member 27 cannot be locked to the wheel 30. A stopper pin 34 that abuts on the locking member 27 protrudes from the member of the elevator 2 so that the rotation of the locking member 27 stops at a predetermined position.

  On the other hand, the connecting member 15 is provided on the beam in the lateral direction of the elevator 2 (longitudinal direction of the parking shelf 4) so as to advance in the horizontal direction toward the parking shelf 4. The connecting member 15 is formed with a long guide hole 35 extending horizontally. On the other hand, two guide rollers 37 are attached to a bracket 36 fixed to the lower surface of the elevator 2 at intervals in the horizontal direction. The guide roller 37 is engaged with the long hole 35. Further, a drive cylinder 38 for advancing and retracting the connecting member 15 is attached to the elevator 2. The connecting member 15 is provided with a driving protrusion 39 on its side surface. The drive protrusion 39 is in contact with the upper surface of the locking member 27. In a state where the connecting member 15 is accommodated in the elevator 2, the driving protrusion 39 is in contact with the upper surface of the base portion 32 of the locking member 27, so that the locking member 27 rotates and the locking portion 31 does not act. Lowering to the position is prevented (FIG. 7).

  7 and 8, only one elevator lock 18 in the width direction of the elevator 2 is shown. However, since the elevator locks 18 are actually installed at the four corners of the elevator 2, the pallet 6 is provided on both the left and right sides. Both the wheels 30 are positioned from the outside by the curved upper surface of the locking member 27, are placed on the elevator 2 in a stable state, and are prevented from inadvertently traversing. This is an elevator lock.

  FIG. 10 shows a contact member 41 having a form different from that of the contact member 20 described above. The contact member 41 is different from the contact member 20 in the shape of the second contact portion 42, and other configurations are not different. The second contact portion 42 is formed as a vertical surface on the side opposite to the hoistway of the upper back portion of the L-shaped cutout portion 43 cut out in an L shape from the lower side of the groove member 22 upward. . In other words, the space in which the stopper 19 engages further on the side opposite to the hoistway of the trapezoidal notch 25 shown in FIG. 4 (the surface on which the second contact portion 24 was formed) toward the side opposite the hoistway. 44 is formed. The hoistway side lower end 43a of the entrance of the L-shaped notch 43 is cut obliquely so that the stopper 19 can easily enter. Since the notch 43 is L-shaped, a lateral locking surface 44a is formed on the hoistway side of the engagement space 44 located in the upper back portion thereof, that is, on the side facing the second contact portion 42. Will be. Further, the lower locking surface 44 b is also formed below the engagement space 44. As a result, once the stopper 19 is engaged with the engagement space 44, the pallet 6 does not easily float upward due to re-vibration or continued vibration, and cannot move horizontally.

  Obtaining such an effect is not limited to an L-shaped notch. In short, it is only necessary that at least a pair of locking surfaces be formed on the hoistway side and below the space where the stopper 19 in the upper back part is engaged. For example, a notch that can be engaged with the stopper 19 may be formed as a stepped slit.

  FIG. 11 also shows another contact member 45. The contact member 45 is also used as a wheel support member independent of the groove member 22. This is because when the groove-type member 22 for pallet reinforcement is not attached to a portion where the function as the contact portions 23, 24, 42 can be exerted, the contact with the groove-type member is separate. A member is provided. The shapes and configurations of the first contact portion 23 and the second contact portion 24 are the same as those of the contact member 20 in FIGS.

  FIG. 12 also shows another contact member 46. The contact member 46 is also used as a wheel support member independent of the groove member 22, similarly to the contact member 45 of FIG. 11. The first contact portion 23 in the contact member 46 has the same shape and configuration as the first contact portion 23 in all the contact members described above. A hook member 48 curved in an inverted J shape projects from the end surface on the side opposite to the hoistway of the main body 46a of the contact member 46 so as to bend downward from the direction of the antihoistway. The second contact portion 47 is formed inside the hook member 48. The anti-hoistway side lower end 46b of the main body 46a of the contact member 46 is cut off obliquely so that the stopper 19 can easily enter. The lower end of the hook member 48 is at the same height as the lower side of the main body 46a of the contact member 46, but may be at a different height.

  Since the present invention has a simple structure and does not require a movable part for each parking shelf, it can be easily applied to, for example, an existing parking apparatus.
