Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking device and a suspension drive mechanism for the parking device.

[0002]

2. Description of the Related Art As a parking device for storing an automobile in two upper and lower tiers, Japanese Patent Laid-Open Nos. 59-217874, 58-153865, 64-24260, 64-43154, and 43-154 are used. 1-62461 or the like, which is an underground buried type having upper and lower two-stage pallets, a practical exploitation sho 57-57259, an actual exploration 1-10158,
A type having only one pallet corresponding to the upper stage is known, such as Jikkai 61-67361. Further, the inventor of the present invention also discloses a two-stage pallet type structure according to Japanese Patent Laid-Open No. 4-209273.

According to Japanese Utility Model Laid-Open No. 64-57259, which is said to be the mainstream type of the above-mentioned one-pallet type, when the vehicle is stored on the road surface corresponding to the lower step or on the floor close to the road surface, it becomes the upper step. If the vehicle is to be taken in and out of the pallet, there is the inconvenience that the vehicle stored in the lower stage must be removed.

According to the above-mentioned Ukaihei 1-1158, Ukaisho 61-67361, etc., when the car is taken in and out of the upper pallet, the upper pallet moved away from the lower storage car and moved away from the fixed position of the mechanical device. Since it is moved to a different place, there are a lot of anxiety factors related to the rigidity of the structure and operational safety.

Further, as shown in the embodiment (Fig. 2) of Japanese Utility Model Application Laid-Open No. 64-57259, when the pallet is engaged with the floor of the automobile, the pallet tilts upwards. Although various examples can be seen, in this case, when the steering wheel is turned to turn in the garage while turning, a difference in height between the left and right wheels occurs, and the inner wheel is higher than the outer wheel. It is a hindrance for the driver who is usually difficult to put in the garage

Furthermore, in the case of the two-stage pallet of the underground storage type,

If the height dimension from the lower pallet to the upper pallet is set according to the height of a person, the dimension between the upper and lower pallet surfaces is about 2 m, and the depth of the basement is about 2.2 m. However, the deeper the basement, the more difficult it is to handle for maintenance, etc., and the higher maintenance costs.

As a means for reducing the height dimension and minimizing the depth of the basement, the front side of the pallet is inclined downward while the upper pallet is engaged with the road surface which is the floor for loading and unloading the automobile. If a mechanism is provided, not only will the stability be impaired depending on the structure, but also if the structure and control are somewhat complicated, it will not be possible to obtain desirable results for a device that requires stability in rigidity and operation.

If importance is attached to the stability of the functions of the upper and lower pallets, it is considered that it is necessary to stably hold the upper pallet to the lower pallet by four columns, and generally four pallets are used. Since the strut structure is selected, the strut interferes with the garage entry work for the lower pallet, and there is a risk of damage accidents when garage entry,

Further, when an arm (link) close type lifting guide mechanism known as a table lifter mechanism (the embodiment shown in Japanese Utility Model Laid-Open No. 64-24260) is used in order to stabilize the operation of the apparatus, the torque efficiency is increased. It is pointed out that not only is it bad, but it requires a drive means by a hydraulic device even though it is shunned for maintenance.

[0011]

SUMMARY OF THE INVENTION The present invention provides a solution to the problems of the conventional parking device described above.

When both upper and lower longitudinal sides (front and rear) of the upper pallet mounted on the lower pallet are oscillated by a predetermined vertical angle, when the upper and lower pallets of the apparatus are both in the raised position, the upper pallet is moved to the upper pallet. When the front of the pallet is in the upward or horizontal state and the pallet is in the lowered position, the front side of the upper pallet is configured to face downward so that only the amount of vertical operation based on the operation of the lower pallet is used. While the pit depth size is reduced to the minimum, the shortage of the required size between the upper and lower pallets that should be determined according to the person's height is due to the upward and downward variable size due to the vertical swing on the front side of the upper pallet. To provide a structure that can be supplemented by

Mainly in an apparatus using an arm close type mechanism or the like, Japanese Patent Laid-Open No. 4-2 related to the invention of the present inventor.
As disclosed in Japanese Patent No. 09273, the advantage of suspension driving without using a hydraulic mechanism as a drive source is great, but the driving means and control means using this suspension driving mechanism are simplified and more stable. A different structure,

To reduce the height of the device and to make the depth of the basement to be shallow,

In a structure having a pallet that operates up and down, and when the pallet is in a state of inclining downward with respect to the floor when the pallet is engaged with a floor for taking in and out of a vehicle, when the pallet is put in a garage, To provide a device that does not cause a difference in height between an inner wheel and an outer wheel at the rear or front of the vehicle at the entrance of the garage,

With regard to the hoisting mechanism as the suspension driving means in these parking devices, apart from the accident of cutting flexible members such as wires, there is a risk of accidents due to breakage of connecting parts such as actuators and transmission system shafts. It was developed mainly for the purpose of eliminating the problem and reducing the cost of the mechanism.

Further, with respect to the upper pallet which is axially fixed at the upper layer position of the lower pallet which is installed in a horizontal state or a nearly horizontal state, the upper pallet is connected to a predetermined position rearward of the pivot shaft of the upper pallet. The control mechanism that applies downward power to the rear side of the pallet is such that the final end of the transmission of the transmission system, in which a suitable number of one or more appropriate suspended parts of the movable part are locked, is the predetermined rear part of the upper pallet. It is characterized in that it is configured to also serve as a control system that is connected to the position and applies downward power to the rear of the upper pallet.

The control mechanism for operating the upper pallet and the drive mechanism as a means for suspending and driving the upper and lower pallets have a double-headed connecting rod axially fixed to a fixed portion at a lower position of the upper pallet, A control system in which one of the connecting heads and a predetermined position behind the upper pallet are connected by a flexible member such as a wire or a connecting rod connects another connecting head, which is a main part of suspension, to the drive-side transmission system. It is composed of an appropriate number of 1 or more.

The control mechanism is provided with at least one rotatable pulley on a fixed portion at a lower position of the upper pallet, and a flexible member such as a wire connected downward at a predetermined position behind the upper pallet. It is characterized in that one of the control systems locked to the rotatable pulley is composed of one or more appropriate number of transmission systems configured to be connected to a drive side transmission system for suspension drive.

Is provided above the lower surface of the lower pallet, and in that component, the mounting surface is placed at a step difference higher than the reference surface of the lower pallet. When the pallet is lowered to the lowest position so that only one of the front and rear wheels of the loaded car is placed on the mounting surface, and the mounting surface of the device is the reference surface, The feature is that the height of the pit can be set to the minimum value and the depth of the pit can be reduced.

If desired, a linear actuator such as a hydraulic cylinder may be used as a means for applying power to the sliding body for moving the position.

[0026]

[Operation] Since the present invention is configured as described above, the following effects can be obtained.

Since the upper pallet to be mounted on the lower pallet is fixed by a pivot shaft provided slightly rearward of the front and rear central portions, the weight of the upper pallet and the vehicle mounted on the mounting surface thereof The weight is relatively balanced and is stably supported by the pivot shaft. The control mechanism connected to a predetermined position behind the upper pallet operates downward when the aggregate structure including the upper and lower pallets is in the raised position. The entrance side is in the state of operating upward and acts to widen the distance with the lower pallet. Therefore, in front of the entrance side of the driver's seat of the car that has been stored in the lower pallet in the back, a height sufficient for a person to stand and move with the upper pallet can be obtained.

On the other hand, when the pallet is in the lowered position, the downward pulling action on the connecting portion of the upper pallet of the control mechanism is loosened, the front side of the upper pallet operates downward, and the front side of the upper pallet moves to the lower stage. It acts to reduce the distance between the pallet and the floor for loading and unloading automobiles, and stays at that position where the distance is set to the minimum necessary for a certain range of vehicle types stored in the lower pallet. That is, with this configuration, the depth of the pit can be set shallow with reference to the height of the vehicle type that allows parking.

The above-mentioned (0018) structure is used as the lower pallet forming means and the guide means for the vertical movement thereof.
When the arm close type table lift mechanism is used, the more balanced and more desirable operation of the load is obtained.

Therefore, the present invention is mainly based on the above-mentioned [001]
8] and [0019], it is desirable to carry out the structure, but if the suspension driving is further performed as the driving means of the pallet (table of the table lift mechanism), the configuration shown in the illustrated embodiment can be obtained. The upper pallet is inevitably controlled along with the operation of the lower pallet by connecting the transmission rear end of the drive mechanism, and can be controlled without providing a special actuator or control means.

When the table lift mechanism is used, the shaft stopper 81 on the pallet side (upper side) of the close arm and the guide mechanism 82 for the arm tip for that purpose are constructed above the bottom surface 11 of the lower pallet, and the apparatus By avoiding the front, the dimension from the mounting reference surface of the lower pallet to the installation surface (foundation) of the device is reduced in the descending limit.

Further, as in the above [0031], the lower pallet has a stepped mounting surface at a position higher than the reference mounting surface in the rear of the pallet, and as a result, a side surface is formed in the stepped part, and the upper step is formed. The mounting parts such as support posts of the pivot supporting the pallet are the side surface and the bottom surface (pallet surface).
Since it is also possible to fasten and fix the two parts having the L-shaped cross section with bolts or the like, it is easy to make the fixing part a robust structure.

On the mounting surface formed at the rear of the lower pallet with a step difference from the mounting reference surface, only one of the front and rear wheels of the loaded vehicle is mounted, and a slight inclination occurs. However, the change in the vehicle height of the loaded car that occurs in this tilted state does not cause a large change in the allowable height of the lower pallet viewed from the reference mounting surface.

Further, in the present invention, in a device constructed such that the front side for loading and unloading a vehicle is inclined downward, when the front side of the pallet is downward and the loading and unloading of the vehicle is allowed, the end portion of the front side of the pallet. Since the substantial distance between the two is approximately horizontal, when the steering wheel is turned to turn in the garage, it is easy to enter the garage without causing a height difference between the inner wheel and the outer wheel.

Moreover, since the front end portion of the upper pallet is substantially horizontal in the lowered position, the front side of the upper pallet is raised upward when the upper pallet is in the raised position. It also has the effect of preventing the storage car from falling off toward the.

The structure and operation of the above (0034 to 0035) can be applied not only to the upper and lower two-stage parking apparatus but also to the upper one-pallet type parking apparatus.
Furthermore, the same applies when used in the two-stage swing type shown in the embodiment of Kaikaihei 1-62461.

The suspension drive mechanism of the present invention comprises a suspension main part which is a contact point between the operating part and the flexible member, a suspension pulley 9 provided on the upper part of the suspension main part, and a fixed pulley for winding-up transmission. When,
A lead screw installed in parallel with a flexible member such as a wire fastened to the fixed pulley, a slide body held by the lead screw and allowed to move in position, and a shaft rotatably attached to the slide body. A movable pulley that has been stopped, and a flexible member such as a wire that is hooked onto this movable pulley and folded back is installed in parallel, and its end is fixed to a fixed portion, and both the forward and reverse directions are fixed to the lead screw. Since the control pulley is configured to be selectively imparted, the movable pulley is moved in position, and the distance between the suspension pulley or the fixed pulley for winding transmission and the movable pulley, and the distance between the movable pulley and the fixed portion are increased or decreased. Provide the same dimensional variation on the sides.

In the above operation, when the movable pulley is operated in the direction away from the fixed portion of the flexible member, the flexible member is suspended by the length of twice the working distance of the movable pulley. The department side will be lifted. On the contrary, when the movable pulley operates toward the side closer to the fixed portion, the flexible member is pulled down to the suspension main portion side, and the collective structure which is the movable portion of the device descends.

Since the movable pulley is screwed by the turning of the lead screw, the lead angle of the lead screw is reduced to provide a function of reducing the moving speed with respect to the input rotational speed of the actuator. To do.

Further, even when a failure occurs in the transmission system from the actuator to the lead screw, since the moving pulley is held by the lead screw, idling caused by the load acting on the suspension drive mechanism, It provides a safe function of avoiding the risk of the movable part of the device falling.

[0041]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The parking device of the present invention will be described below with reference to the embodiments shown in FIGS.

As can be seen from the front view (FIG. 1) of the device, the basic form can be constructed in a symmetrical form. This embodiment is constituted by an arm close type table lift mechanism, and the lower pallet (table) 1 is supported by arms 8 which are provided in a closed state and are axially fixed at their center positions.

On both the left and right sides of the lower pallet 1, the mounting reference planes 12 are located rearward of the longitudinal center of the pallet.
The pivotal support portion 2 is constituted by a side edge portion and a pillar fixed to a seating surface having an L-shaped cross section by the vertical surfaces on both the left and right sides of the mounting surface 13 formed in a stepped manner as main components. And
The upper pallet 3 is axially fixed at a proper position on the upper portion of the pivotal support portion 2 by a pivotal support shaft 31.

The lower pallet is supported by the arm 8 and guided so as to be horizontal, and is allowed to move up and down together with the upper pallet. The drive source is a drive device 10 which is fixedly equipped with a suspension mechanism on the left and right sides of the device, and is suspended by a transmission system 7 of the drive device. In addition, the suspension drive mechanism is the transmission system 7
The suspension main part 60 (or 6) set at the lower part of the pivot part 2 fixedly provided with the lower pallet by the flexible member of
1) is locked and suspended.

The lower pallet 1 is adapted to engage with the floor FL of the vehicle in its operating and raised position. The upper pallet 3 is supported by a pivot shaft 31 and is brought into a state in which a front downward slope is generated at a lower limit position (FIG. 3) of the pallet and engages with the floor FL. Due to the above function, the loading and unloading of the automobile from the floor FL is allowed in each pallet.

Incidentally, each pallet is described in JP-A-3-5926.
As shown in FIG. 7, another stop position serving as an operation origin may be provided at an intermediate point between the ascending position and the descending position.

The upper pallet 3 has an end 30 on the loading / unloading side of an automobile bent upward, and when the pallet is engaged with the loading / unloading floor of the automobile, the end 30 is horizontal or nearly horizontal. Is configured to be.

In this structure, the upper and lower pallets (1
And 3) both move up and down, but as the driving means,
The drive unit 10 is adapted to function.

With respect to the drive unit 10 and its transmission system 7 and control system 4 ', the configuration of FIG. 2 will be described. A pulley 6 in which a flexible member such as a wire of a transmission system 7 of the drive device 10 sets a suspension main part of the aggregate structure of the upper and lower pallets.
It is suspended while being locked at 1. Then, the flexible member is locked by using another pulley 51 provided at the rear of the device as a turning point and stretched upward, and the final end thereof is connected to a predetermined position 32 of the upper pallet 3 and the same. Downward power is applied to the rear of the pallet. The flexible member of the transmission system 7 communicates with a drive device 10 described later.

A modified structure of FIG. 2 relating to the drive unit 10 and its transmission system 7 and control system 4 will be described with reference to FIG. The flexible member such as the wire of the transmission system 7 of the drive device 10 is
It is connected to one connecting head 60 of a double-headed connecting rod that is axially fixed to the lower portion. And another connecting head 50 is the upper pallet 3
In the same manner as in FIG. 2, the rear side of the upper pallet 3 is pulled downward by the power at the initial stage of the suspending action of the drive unit 10, and is connected to the appropriate position 32 of the upper stage by a flexible member or a connecting rod. It is configured such that the front side of the pallet 3 is operated upward and the same operation state can be maintained.

When the driving device 10 operates and the upper and lower pallets leave the lower limit position to reach the ascending position, the rear part of the upper pallet operates downward and the front side is in the upward state. . On the other hand, when the pallet descends to the lowest part, the control system 4 or 4'for operating the rear part of the upper pallet 3 downwards is loosened by the operation at the end of suspension, so that the front side of the upper pallet 3 faces downward. In this embodiment, in this state, loading and unloading of the automobile on the upper pallet is allowed.

Among the guide mechanisms for supporting the vertical movement of the upper and lower pallets, that is, the assembly structure consisting of the upper and lower pallets, the guide mechanism 82 to be installed on the lower pallet side is located below the bottom surface 11 of the lower pallet. It is configured so that it does not stick out. With this configuration, this lower pallet 1
Provides a close contact with the upper surface of the lower pedestal, which is the basis of this structure, and can further reduce the distance H from the mounting reference surface 12 of the lower pallet to the installation base surface of the apparatus. It should be noted that the placement surface 1 having a different level from the placement reference surface 12 of the lower pallet
3 can be said to be formed as a result of forming a space for accommodating the guide mechanism 82, but forms an L-shaped cross section as a solid seating surface for fixing the pivotal support portion 2 and the lower pallet 1 to each other. It is also a means to do.

The suspension drive mechanism of the parking apparatus of the present invention will be described below with reference to the transmission system diagram of FIG. 4, which is a configuration applied to the parking apparatus of the above embodiment.

At the upper position of the suspension main part, which is designated by 61 according to FIG. 2 and 60 according to the embodiment of FIG. The transmission system 7 of the flexible member locked to this pulley is locked to another fixed pulley 104 for changing the direction. As is apparent from this figure, the fixed pulley 104 is used as a means for setting the direction of the transmission system, and it can be said that the fixed pulley 104 and the pulley 9 are common constituents in terms of the function of the present invention.

In the drive device shown in the transmission system diagram of FIG. 4, the flexible member (7) locked to the fixed pulley 104.
Is locked by a movable pulley 103 which is axially fixed to the sliding member 105 so that only rotation is possible and moves, and further folded back and fixed by a fixing portion 101.

The sliding member 105 includes two guide shafts 1
The lead screw 102 is held by No. 06, and is slid by being screwed by the lead screw 102 equipped with the center of the guide shaft as an axis. Therefore, the movable pulley 103 axially fixed to the sliding member moves in position by the rotation of the lead screw 102.

The drive source for imparting rotation to the lead screw may be an electric motor, a hydraulic motor, a pneumatic motor, or a manual drive, but as a simple structure without using the lead screw, a cylinder or the like is used. The sliding member 105 may be provided for direct operation.

On the other hand, the end of the flexible member (7) is fixed to the fixed portion 101. Therefore, the moving pulley 103
Is moved to a side distant from the fixed pulley 104 and the fixed portion 101, the suspension side of the flexible member (7) is wound up twice as much as the moving amount, so that the pallet assembly structure rises. When the movable pulley 103 moves to the opposite side, the pallet assembly structure descends by a distance that is twice the operation amount.

In the above description, one of the transmission systems is explained. However, by combining this structure or by equipping two of the transmission systems, the parking system of the present invention can be realized. In addition to the suspension drive on both the left and right sides of FIG. 1, a desired function that can adapt to the torque distribution of the load can be obtained.

[0060]

According to the present invention, the following effects can be obtained by virtue of the configuration and function described in detail above.

The upper pallet is swingably supported by the pivot shaft 31 provided at the longitudinal center of the upper portion of the pivot portion mounted on the lower pallet, so that the structure is excellent in load balancing function. It has a stable structure. Therefore, the upper pallet provides a stable function. Further, even if a wire cutting accident of the suspension driving mechanism that supports the upper pallet occurs, the dropping speed and impact unique to the upper pallet will be small due to the load balancing function.

The upper and lower pallets, that is, the pallet aggregate structure, is controlled by suspension drive. Since the drive device also serves as a control means for swinging the upper pallet, the control means for the upper pallet is separately provided. It is not necessary to provide it and is significantly simplified.

After the lowering operation of the lower pallet is completed,
When the suspension drive is continued, the upper pallet 3 has a function of supplementing the downward operation of the front by the vertical swing. With this function, the working distance of the lower pallet can be set to a distance less than the working distance due to the swing of the upper pallet from the set distance between the lower pallet and the upper pallet. As a result, the depth of the basement to be set according to the working distance of the lower pallet can be made shallow. Therefore, when the basement is required, the construction cost of the installation foundation of the device is inexpensive.

According to the present invention, the end of the vertically swingable pallet on the vehicle entry / exit side is bent upward. With this configuration, when the pallet that swings up and down is engaged with the floor for loading and unloading the vehicle, the pallet is in a state of rising up and down, but the entry / exit side of the vehicle is approximately horizontal, and when entering the garage while turning. In addition, since there is no difference in height between the inner and outer wheels of the automobile, particularly the phenomenon that the inner rings are high, the operation when the vehicle is parked becomes easy.

In the present invention, the arm close type lift mechanism can be used as the lower pallet constituting means. Regarding the constitution, the cross arm shaft stopper 81 and the arm tip guide mechanism 82 are the lower pallet. Since the lower pallet is lowered, the minimum height from the mounting reference surface 12 of the lower pallet to the installation base surface of the apparatus can be set lower. This has the effect of making the pit depth of the lower pallet even shallower, and has a significant economic effect on the construction of the pit and the installation foundation.

With regard to the suspension drive mechanism, which is another problem to be solved by the present invention, by providing a pulley that moves linearly and operating the movable pulley 103 by the lead screw 102, the same operation is performed. The actuator itself does not require a significant deceleration function. In other words, by reducing the lead angle of the lead screw to be used, the deceleration width can be set to a large value by the unique function of this device, which eliminates the need for a complicated decelerating function actuator and greatly stabilizes the function and reduces the manufacturing cost. Is.

Further, according to the present invention, the movable pulley 103 is moved by using the lead screw 102, so that the lead screw 102 can be moved from the actuator provided.
When an accident such as breakage that occurs up to the time occurs, there is an effect that a large accident such as a pallet drop due to a heavy load on the pallet aggregate structure can be avoided.

According to the suspension driving means of the present invention, since it is not necessary to wind a suspension member such as a wire around a drum or the like, as a result of winding around the drum or the like, damage or wear of the wire due to poor winding is less likely to occur. The effect of providing a suspension drive with excellent performance is great.
