Description

  For example, the present invention eliminates gaps that have conventionally occurred between pallets or between the pallets and the approach path for getting in and out of the vehicle, such as small items such as vehicle keys and garbage. Parked on the pallet, preventing the heel from falling into the pit and high heels from being caught in the gap, and / or eliminating at least the level difference between the uppermost pallet and the approach path located on both sides of the pallet. The present invention relates to an improvement of a pit type parking device, particularly its uppermost pallet, which allows a wheelchair to enter near the door of a vehicle.

A conventional pit type parking apparatus is described in, for example, Patent Document 1.
As shown in FIGS. 11 (a) and 11 (b), the pit type parking apparatus 100 has a pallet coupling body 104 made up of three pallets 101, 102, and 103 that are integrally connected at intervals in the vertical direction. The upper pallet 101 is located on the ground surface, the middle pallet 102 and the lower pallet 103 are in the pit P, and only the upper pallet located at the center of the upper pallet 101 is flat. It is a wheelchair pallet 105.

By the way, in such a parking device 100, it is inevitable to dispose an elevating means 106 for raising and lowering the pallet coupling body 104 between the pallet coupling bodies 104, 104. When the space is effectively used as an approach path for getting on and off a vehicle on which a pallet is parked, it is common to dispose an approach path plate 107 covering the lift means 106. is there.

However, such a parking device 100 is usually provided with a sprocket 108 fixed to both ends of the drive shaft as the lifting means 106, and a rotating body 109 rotatably connected to both front and rear sides of the lower pallet. Are moved up and down through a chain 110 that is swung around them. In the case of the lifting means 106, the lower pallet 103 of the pallet coupling body 104 is raised to the ground surface position G due to the structure of the apparatus. For this reason, it is necessary to dispose the sprocket 108 somewhat above the ground surface position G due to the relative positional relationship between the sprocket 108 and the rotating body 109. Naturally, the approach path plate 107 is also positioned above the ground surface position G.

In the parking device 100 described in Patent Document 1, by providing the flat wheelchair pallet 105, there is no step in the front-rear direction of the wheelchair pallet 105, and the wheelchair pallet 105 is moved in the front-rear direction by the wheelchair C. Although it is easy, there is a gap d between the wheelchair pallet 105 and the pallets 101 to 103 of the pallet connecting body 104 adjacent thereto as shown in FIG. Or when the approach path is disposed above the lifting means 106, the upper surface of the approach path plate 107 is positioned above the upper surface of the pallet 101 or the like at the ground surface position. Therefore, a step S1 as shown in FIG. 11 (a) occurs between these upper surfaces. In addition, since the pallet 101 itself is bent in the pallet width direction from the viewpoint of ensuring the strength, the pallet itself generally has a step S2.

When the gap d (for example, 40 mm or less) occurs, there is a problem that small items such as vehicle keys or garbage may fall into the pit through the gap d, or high heels may be caught in the gap d. When the gap d is wider than the wheel width of the wheelchair C, the wheelchair C may be removed. Therefore, it is necessary to control the gap d as narrow as possible, but there is a limit to controlling the gap d narrowly. is there.

Further, when the steps S1 and S2 occur, for example, the door of the vehicle V parked by the wheelchair C from the wheelchair pallet 105 to the pallet 101 or the like at the ground surface position G of the pallet coupling body 104 adjacent thereto. Movement in the direction approaching the mouth (pallet width direction) is difficult due to the presence of the step S1 due to the approach path and the step S2 of the pallet 101 and the like, and the presence of such steps S1 and S2 is the wheelchair pallet 105. The wheelchair C is placed next to the vehicle V parked on the vehicle-mounted pallet 101, and it becomes a great obstacle to get on and off from the opened door opening.

  According to the first aspect of the present invention, the uppermost pallet has an upper surface whose width dimension is larger than the width dimension between the access path plates located on both side ends of the pallet, and the uppermost pallet is at the ground surface position. When both side ends of the uppermost pallet overlap with the approach path plate, for example, between the pallets and between the pallet and the approach path for getting on and off the vehicle on the side of the pallet. Since the gap that has occurred does not occur, it is possible to prevent small items such as vehicle keys, garbage, etc., falling into the pit and high heels from being caught in the gap, as occurred in a conventional parking apparatus.

According to the second invention, the uppermost pallet has a flat shape on the entire upper surface, and when the uppermost pallet is at the ground surface position, the uppermost pallet is placed on both side ends of the uppermost pallet. By forming a substantially flat first plane area together with the approach path plate, it is possible to facilitate entry of a vehicle parked on the pallet with a wheelchair, Since the approach path plates attached to both end sides are substantially flat, when entering the vehicle in the uppermost pallet, the approach paths on both sides are added rather than the pallet width, which is the normal vehicle storage space. There is also an advantage that the vehicle can be taken in and out using a wide width region.

Furthermore, according to the third invention, by providing both configurations of the first invention and the second invention, the effects of both the first and second inventions can be combined, and furthermore, a pallet other than the uppermost pallet. Can be used as a parking space, and the top pallet can be used as a multipurpose space. For example, when the uppermost pallet is on the ground surface, using the wide flat area formed by these uppermost pallet and the approach path, the same as that performed on the normal ground surface, for example, bricks It is possible to form a garden by tensioning.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 3 are parking apparatuses according to the present invention, FIG. 1 is a front view, FIG. 2 is a left side view, FIG. 3 is a plan view, and FIGS. 4 to 6 are views showing a pallet unit. 4 is a left side view, FIG. 5 is a front view, FIG. 6 is a plan view, and FIG. 7 is a plan view of the lowermost pallet.

  The pit type parking apparatus 1 according to the present invention has a structure in which at least two pallets 4 and 5 that are fixedly connected in a vertical direction 3 via a connecting member 2 are used as one pallet unit 6, downward from the ground surface 7. In the formed pit 8 is a multistage double row pit type parking device in which at least one pallet unit 6 is installed so as to be movable up and down. In FIG. As an example, a case where the pallet units 6a to 6e are arranged side by side in two and in two pits 8a and 8b formed downward from the ground surface 7 is shown.

In addition, the parking apparatus 1 further covers the pallet units 6a to 6e on both side ends with a lifting and lowering means 9 for raising and lowering the pallet units 6a to 6e, and an upper part of the lifting and lowering means 9 so as to cover the pallet. 4 and 5 is provided with an entrance path plate 10 for getting on and off the vehicle parked, and among the pallets 4 and 5 constituting the pallet units 6a to 6e, the uppermost stage located at the uppermost stage. The pallets 4a to 4e have the ground surface position A as the basic position, the other pallets 5a to 5e have the pit in-position B as the basic position, and the lowermost pallets 5a to 5e are positioned at the lowermost level by the lifting means 9 The pits can be moved up and down between the pit position B and the ground surface position A.

For example, as shown in FIGS. 2 and 9, the elevating means 9 includes one of the lower pallets 5 out of the two columns 11 and 12 fixed to the pit bottom surface position U on the side of the lower pallet 5. A driving means 13 such as a driving motor, which is fixed to one of the support pillars 11 and 12, or the support pillar 11 on the front side in FIG. The rotating shaft 15a is rotatably connected to the drive shaft D connected to the driving means 13 and having the sprockets 14a and 14b fixed to both ends thereof, and the lower pallet 5 below the sprockets 14a and 14b. , 15b and the sprockets 14a, 14b and the rotating bodies 15a, 15b located below the sprockets 14a, 14b, and the sprockets 14a, 14b and the rotating bodies 15a, 15b, respectively. At the ground level near the sprockets 14a, 14b As shown in FIG. 9, parallel holding means 24 for maintaining a parallel balance when raising and lowering the pallet is provided.
As the parallel holding means 24, for example, rotating bodies 25a and 25b are further provided on both front and rear sides of the lower part of the lowermost pallet 5, and the rotating body 25a is coaxial with the rotating body 15a. The balance chain 26 is turned around 25b, and one end 26a of the balance chain 26 is fixedly connected to the ground surface position on the other side of the lowermost pallet 5, and the other end 26b is placed on the pit bottom surface position on one side of the lowermost pallet 5. What is necessary is just to employ | adopt the structure fixedly connected.
Then, by rotating the drive shaft D of the elevating means 9 in two forward and reverse directions, the pallet unit 6 can be moved so that its lowermost pallet 5 is moved between the in-pit position B and the ground surface position A. What is necessary is just to make it the structure to raise / lower.

  That is, the drive means 13 is driven, the drive shaft D is rotated, and the lifting chains 16 and 17 are wound up to raise the pallet unit 6 until the lowermost pallet 5 reaches the ground surface position A. Along with this, the remaining pallets such as the uppermost pallet 4 can be raised simultaneously, while the pallet unit 6 can be lowered by rotating the drive shaft D in the opposite direction.

  Although FIG. 9 shows a configuration in which two adjacent pallet units are moved up and down by one drive means 9, a configuration in which one pallet unit travels by one drive means may be used.

The main feature of the configuration of the present invention is the optimization of the uppermost pallet 4. More specifically, in the first invention, the uppermost pallet 4 has an upper surface whose width dimension is the opening of the pit. When the uppermost pallet 4 is larger than the width dimension and the uppermost pallet 4 is at the ground surface position A, both side ends of the uppermost pallet 4 are configured to overlap with the approach path plate 10. The upper pallet 4 has a flat shape on the entire upper surface, and when the uppermost pallet 4 is at the ground surface position A, the uppermost pallet 4 is for an approach path provided on both side ends of the uppermost pallet 4. A substantially flat first plane region Fs (shaded region in FIG. 3) is formed together with the plate 10, and the third invention is to have both the configurations of the first and second inventions.

That is, as in the first invention, the uppermost pallet 4 is formed such that the width dimension Wp of the upper surface thereof is larger than the width dimension Ws between the entrance path plates located on both side ends of the pallet, and When the pallet 4 is at the ground surface position A, by configuring the side end portions 18 of the uppermost pallet 4 so as to overlap the approach path plate 10, for example, between the pallets 4 and 4, or between the pallet 4 and the approach path. Since there is no gap d generated in the past with the board 10, small items such as vehicle keys and garbage, etc., which have occurred in conventional parking devices, fall into the pit, or high heels in the gap d. Can be prevented from being caught.

In addition, as shown in FIG. 4, the uppermost pallet 4 is configured so as to overlap the edge portion of the pit 8 at least at the front end portion 19 and more preferably at both the front end portion and the rear end portion. This is advantageous because the formation of gaps when the pallet 4 is at the ground surface position A can be further reduced.

In addition, when there is a restriction on the installation space of the parking device 1, especially the depth space, there is a case where the rear edge of the pit 8 may not exist. More preferably, the front end 19 is provided at three ends.

In the second invention, the uppermost pallet 4 is flat on the entire upper surface, and when the uppermost pallet 4 is at the ground surface position A, the uppermost pallet 4 is positioned on both sides of the uppermost pallet 4. By forming the substantially flat first plane region Fs together with the approach path plate 10 provided on the end side, the vehicle V parked on the pallet 4 can be easily entered by the wheelchair C. Since the uppermost pallet 4 and the approach path plate 10 provided on both side ends thereof are flat, when storing the vehicle V in the uppermost pallet 4, compared to the pallet of the conventional parking device, There is also an advantage that the vehicle can be taken in and out using a wide width region including the approach paths on both sides.

Further, in the third invention, the uppermost pallet 4 is formed such that the width dimension Wp of the upper surface thereof is larger than the width dimension Ws between the entrance path plates located on both side ends of the pallet 4, and the uppermost pallet. When both end portions 18 and 18 of 4 overlap with the approach path plate 10 and the uppermost pallet 4 has a flat shape on the entire upper surface, and the uppermost pallet is at the ground surface position, the uppermost pallet Is formed with the first flat area Fs which is substantially flat and has no gaps, together with the approach path plates 10 provided on both side ends of the uppermost pallet 4. Can be played.

In particular, at least two pallet units in the same pit 8, for example, as shown in FIG. 1, three pallet units 6a to 6c are juxtaposed in the pit 8a, and the uppermost pallets 4a to 4c are at the ground surface position A. In some cases, all the uppermost pallets 4a to 4c of all the pallet units 6a to 6c juxtaposed are formed with the plurality of first planes formed together with the approach path plates 10 provided on both side ends of the uppermost pallets 4a to 4c. region Fs is continuous with the ground plane and substantially flat over the entire opening of the pit, as shown in FIG. 10, if the structure forming the second planar area F _L, the plane of the large area without gaps between the pallet Since the area is obtained, for example, only the pallet 5 having the basic position in the pit other than the uppermost pallet 4 is a parking pallet, and the uppermost pallet 4 is not used as a parking space, but for other uses, for example, As in the case of a normal ground surface, bricks and soil can be spread on a pallet and used for multipurpose purposes such as a garden.

  Here, the reason why the first plane region Fs is “substantially flat” is to include a case where there is a gap between the first pallet and the uppermost pallet in the second invention, and in the third invention, Since the side end portions 18 and 18 of the pallet are configured to overlap with the approach path plate 10, strictly speaking, there is a small level difference corresponding to the plate thickness of the uppermost pallet 4 at the portion overlapping the entrance path plate 10. This is to include a case having such a small step.

  Therefore, in the latter case, the plate thickness of the uppermost pallet is preferably 5 mm or less, and preferably in the range of 2 to 4 mm from the viewpoint of flattening. In addition, if the uppermost pallet is flat and the plate thickness is thin, the pallet strength tends to be insufficient. In this case, as shown in FIG. It is preferable to reinforce with a reinforcing material (aggregate) such as a steel frame at a position on the back side corresponding to the tire position of the front and rear wheels. In the case of a conventional in-vehicle pallet bent in the width direction from the viewpoint of securing strength, etc., if the step between the upper surfaces is usually about 20 mm, the thin plate thickness (5 mm) of the uppermost pallet of the present invention. It can be said that the step below is very small.

  The first to third inventions are based on the premise that the approach road plate 10 is fixed to the ground surface position A. In the conventional parking apparatus, as described above, the structure of the lifting means 13 is as follows. In order to raise the upper and lowermost pallets 5 to the ground surface 7, the approach path plate 10 had to be disposed above the ground surface position A.

On the other hand, in the present invention, the pits 8 are made deeper than the conventional parking device, and the rotating bodies 15a and 15b connected to both sides of the lower front and rear parts of the lowermost pallet 5 are compared with the conventional device. If the sprockets 14a and 14b at both ends of the drive shaft D can be arranged below the ground surface 7 if they are arranged at positions far away from the top surface of the lowermost pallet 5, this approach The road plate 10 can be arranged at the position A on the ground surface.

  Here, the vertical distance L from the upper surface of the lowermost pallet 5 to the connecting position of the rotating bodies 15a, 15b is in the range of 110 to 200 mm, preferably in the range of 130 to 150 mm, and more preferably about 140 mm. . If it is less than 110 mm, it is difficult to raise the upper surface of the lowermost pallet to the ground surface position A, and if it exceeds 200 mm, the pit must be dug deeply, which is not preferable in terms of workability and manufacturing cost. It is.

   In the second and third inventions, since the configuration in which the uppermost pallet 4 is flattened is adopted, when the vehicle V is parked on the pallet 4, depending on the case, from the side end of the uppermost pallet 4 Although it is assumed that the driver parks the vehicle without knowing it at the improper position, it is extremely dangerous to raise the uppermost pallet 4 in such a state.

  For this reason, in such a case, for example, the upper surface portion of the pallet side end when the vehicle is parked at an inappropriate position, and the vehicle tire is out of the parking position, the pallet region at the inappropriate position, If a pressure (load) sensor is attached, even if the vehicle is parked in an inappropriate position, the pressure sensor is activated and the parking device is deactivated when the vehicle tire steps on the pressure sensor. At the same time, it is preferable to notify the driver by an alarm or the like.

  In the present invention, although the pallet other than the uppermost pallet can be made flat, the pallet unit is connected by a connecting material, and two pallets are provided in the upper space between the pallet and the entrance path. However, although it is not very suitable as a pallet for entering and entering the approach road with a wheelchair, it can be used if it has a merit by making it flat.

  The above description is merely an example of the embodiment of the present invention, and various modifications can be made within the scope of the claims.

  For example, as shown in FIG. 8, if a gap filling material 22 having a T-shaped cross section is disposed between the approach path plate 10 and the edge 21 of the pit 8, the entire opening of the pit 8 is wide with no gap d. This is preferable in that a planar region can be formed.

  In addition, when the top pallet 4 is used as a wheelchair pallet, the width of the approach path (passage) in conformity with the standards of the Multi-story Parking Lot Industry Association Mechanical Parking Lot Technical Standards-the same explanation (2004 edition) Is set to 0.9 m or more, and when it is necessary to consider turning of the wheelchair C at the portion of getting on and off the vehicle V, the width is preferably 1.4 m or more with respect to the traveling direction of the wheelchair.

Further, as shown in FIG. 3, it is preferable to provide wheel stoppers 20 at both rear portions on the upper surface of the pallet in order to determine the rear stop position of the vehicle V, as shown in FIG. the arrangement whether setting of such chock 20, and as it does not inhibit the formation of the first planar region Fs and a second planar area F _L where the above.

  In addition, when the uppermost pallet 4 is made flat, the proper tire position when parked is shown in FIG. 10 so that the driver can visually recognize the proper stopping position in the width direction, as shown by the color-coded line 23 in FIG. It is preferable to color-code the upper surface of the pallet at other portions.

  In the above description, only the pallet unit consisting of the uppermost pallet with the basic position at the ground level and the lowermost pallet with the basic position in the pit has been described. In the invention, it is a matter of course that the pallet whose basic position is in the pit has two or more stages.

According to the first aspect of the present invention, the uppermost pallet has an upper surface whose width dimension is larger than the width dimension between the access path plates located on both side ends of the pallet, and the uppermost pallet is at the ground surface position. When both side ends of the uppermost pallet overlap with the approach path plate, for example, between the pallets and between the pallet and the approach path for getting on and off the vehicle on the side of the pallet. Since the gap that has occurred does not occur, it is possible to prevent small items such as vehicle keys, garbage, etc., falling into the pit and high heels from being caught in the gap, as occurred in a conventional parking apparatus.

According to the second invention, the uppermost pallet has a flat shape on the entire upper surface, and when the uppermost pallet is at the ground surface position, the uppermost pallet is placed on both side ends of the uppermost pallet. By forming a substantially flat first plane area together with the approach path plate, it is possible to facilitate entry of a vehicle parked on the pallet with a wheelchair, Since the approach path plates installed on both side ends are flat, when storing a vehicle in the uppermost pallet, the width of the entry path on both sides is wider than the pallet width, which is the normal vehicle storage space. There is also an advantage that the vehicle can be taken in and out using the width region.

Furthermore, according to the third invention, by providing both configurations of the first invention and the second invention, the effects of both the first and second inventions can be combined, and furthermore, a pallet other than the uppermost pallet. Can be used as a parking space, and the top pallet can be used as a multipurpose space. For example, when the uppermost pallet is on the ground surface, using the wide flat area formed by these uppermost pallet and the approach path, the same as that performed on the ordinary ground surface, for example, bricks It is possible to form a garden by tensioning.
