Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, in a parking device capable of storing automobiles in a stacked state, automatically operates the lifting and lowering of the pallet section when the operator should enter the lifting range when operating the lifting and lowering section. The present invention relates to a parking device that has the safety of operating an alarm as well as being stopped, and also prevents forgetting to remove the key after operation.

[0002]

[Prior art]

 There are various types of conventional parking devices, from two to several tens of cars, but in recent years, in order to effectively use the parking space, a pillar is erected on the ground and the pillar is attached to the pillar. Parking devices that have a pallet that moves up and down only through a drive member such as a chain connected to a motor are becoming widespread. This stacking type parking device is provided with a control unit such as an elevating button for raising and lowering the pallet unit, but a person who operates this control unit (hereinafter referred to as an operator). Since it is rare that a technician operates a specific technician and mishandles it with due consideration of the risks involved, it is sufficient to simply have a control unit that can raise and lower the pallet unit. There was no parking system that added safety to the operator.

[0003]

[Problems to be solved by the device]

 The present invention focuses on providing a parking device in consideration of safety by providing a lid opening / closing detection sensor in the operation section, and an area sensor for detecting the detection sensor and the operator's state. Try to solve the problem. In other words, as the number of ordinary households owning multiple vehicles has increased along with the increasing demand for automobiles in recent years, stacking type parking devices that can be used by ordinary households with few parking spaces have begun to be used. There is a possibility that even an unskilled person such as a housewife or a child may be operated, and due to employment problems, etc., there may be cases where the operator must be hired as an amateur operator.

On the other hand, since the parking device lifts and lowers heavy objects such as automobiles, most of them are made of metal such as steel, and even if they are accidentally operated and hit the operator lightly, serious injury may result. There is a risk of falling.

Therefore, the inventor of the present application presupposes that a part of the operator's body should fall within the ascending / descending range of the ascending / descending pallet, assuming that the operator makes an erroneous operation. The pallet section is forcibly stopped automatically, and there is the safety of notifying the danger with an alarm such as a buzzer. Also, even if the key for operating the key switch is forgotten after the operation, the alarm is activated. The purpose is to provide a parking device that also has a function of notifying a signal to prevent forgetting the key.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a pillar standing on the ground or the like, a pallet portion that is moved up and down along the pillar, a driving means for driving the pallet portion up and down, and a driving means. A parking device including an operation section electrically connected to the operation unit, wherein a key switch electrically connected to the operation section and an open / closed state of a lid member provided independently for opening / closing the operation section are detected. A possible lid opening / closing detection sensor and an area that can be activated when this detection sensor detects that the lid member is in the open state, and can identify whether the operator is outside the lifting range of the pallet section. A parking device comprising: a detection unit including a sensor; and a determination unit that determines whether the operation of the pallet unit is forcibly stopped or the alarm is activated based on a signal from the area sensor. Provide It

[0007]

[Action]

 In the parking device of the present invention configured as described above, when the operator opens the lid member provided on the operation portion, the lid open / closed detection sensor detects that the lid is open, and thus the area sensor is activated. Activate. When the operator is within the detection range of the area sensor, the signal from the area sensor is transmitted to the control means. Then, by inserting a key into the key switch and turning on the key to turn it on, the drive means is activated, and the operating portion is pushed to move the pallet portion up and down in the desired direction. On the other hand, even when the operator is not in the detection range of the area sensor, the signal from the area sensor is transmitted to the control means. When this signal is sent, the operation of the pallet section is forcibly stopped by electrically shutting off the drive means and the alarm device such as a buzzer is activated under any condition, and the operator Inform them of the danger.

Further, even after the lifting operation is completed, unless the lid opening / closing detection sensor detects that the lid is closed, the area sensor is kept attached to the key switch. If there is no operator in the detection range, the alarm is activated even when the signal from the area sensor is transmitted to the control means to notify the operator that he / she has forgotten to remove the key.

【Example】

 The details of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a view showing a state in which a parking device according to an embodiment of the present invention is used, and FIG. 2 is a front view showing a main part of the present invention. Reference numeral 1 designates a pillar standing on the ground or the like, and a driving member such as a chain associated with a motor (not shown) is provided on the pillar 1, and the pallet portion 2 is connected via the driving member such as the chain. Move up and down along the pillar. In addition, although the pillar 1 in this embodiment is erected on both sides of the pallet portion 2 in the width direction, it is of a cantilever type or the like in which the pillar 1 is erected only on one side. I don't mind.

Reference numeral 3 denotes an operating portion for moving the pallet portion 2 up and down. When the operating portion 3 is pushed in the direction of an up arrow, the motor is rotated forward to raise the pallet portion 2. When the downward arrow is pressed, the motor is rotated in the negative direction to lower the pallet portion 2 as is well known.

Reference numeral 4 denotes a lid opening / closing detection sensor that detects an open / closed state of a lid member 5 that is openably / closably provided so as to cover at least the operation portion. As shown in this example, in addition to the operation unit 3, a position display unit 6 for displaying the ascending / descending position of the pallet unit is mixed in one panel 7, and the lid member 5 can be opened and closed with respect to the panel 7. By providing it, it is possible to know the state of the pallet unit 2 while operating the operation unit 3. Further, a lid opening / closing detection sensor 4 capable of detecting the open / closed state of the lid member 5 is also installed in the panel 7, and for example, the lid member 5 is made of metal and has a detection distance of several mm to several tens. If the existing magnetic sensor set to mm is used, the open / closed state of the lid member 4 can be easily and inexpensively detected.

Reference numeral 8 denotes an area sensor that operates when the detection sensor detects the open state of the lid member 4 and can identify whether or not the operator is outside the lifting range of the palette unit 2. Various types of area sensors 8 are commercially available. For example, a plurality of optical sensors may be used to detect a certain range, but in order to prevent circuit complexity, this device uses It is simplified by using an optical sensor used for automatic drainage of toilets. When such an area sensor 8 is used, the cost can be reduced and it is suitable for use in a non-precision machine such as a parking device, but the mounting direction of the area sensor 8 in this case is limited. That is, this type of area sensor 8 emits light rays in a fan shape that is symmetrical and open from the center of the mounting direction. Therefore, if the area sensor 8 is simply mounted on the front side wall of the column 1, it will detect the elevation range of the pallet portion 2. . There is no problem if it is attached to the outer side wall of the column 1, but for example, in general households, the block wall is often close to the outer side of the column 1 of this device, and there is no space for the operator to enter. Therefore, in order to set this mounting direction to a position outside the lifting range of the lifting pallet unit 2 and at which the operating unit 3 recognizes the presence or absence of the operator in a substantially facing direction, the area sensor 8 is directed outward. Installed. Specifically, as shown in Fig. 3, a type that detects a range of about 70 cm by expanding the symmetrically about the mounting position by about 30 ° is used to detect the shaded area in the figure and One side edge is set outside the lifting range of the pallet unit 2.

The presence or absence of the operator is identified by the area sensor 8, and this identification is transmitted to the control means 9 by an electrical H, L signal or the like. For example, the L signal is transmitted when the operator is within the ascending / descending range of the pallet unit 2 within the area sensor 8 and the H signal is transmitted when the operator is outside the ascending / descending range. The control means 9 which receives one of these signals, for example, via a relay circuit, electrically connects one to the activation wiring of the drive means, so that the drive means is activated when the H signal is transmitted. The drive means can be forcibly stopped by electrically cutting off. Further, when the H signal is transmitted, a well-known alarm device such as a buzzer sound or light operates in a similar manner, and when the driving means is stopped, the alarm device emits an alarm device to cause a danger to the operator. Can be notified.

The conceptual diagram of the present invention described above is shown in FIG. 4, and will be described below together with the operation. First, when the operator opens the lid member 5 provided on the operation section 3, the lid opening / closing detection sensor 4 detects that the lid is open. The area sensor 8 is activated by this detection. When the operator is within the detection range of the area sensor 8, the signal from the area sensor 8 is transmitted to the control means 9, so that the drive means is not shut off and the activated state is maintained. In this state, the operating section 3 may be operated to move up and down, but in the present embodiment, a key switch 10 is provided to prevent the operation by a person other than the operator, and the key switch 10 is used by the operator. It is possible to move up and down by the operation unit 3 only by inserting the key held by the and rotating it in the ON direction in the figure. A key for restricting the opening and closing of the lid member 5 with the key may be provided to restrict the opening and closing of the lid by a person other than the operator. Then, the operating portion is continuously pushed upward or downward in a desired direction to move the palette portion 2 up and down.

On the other hand, when the operator is out of the detection range of the area sensor 8, a signal from the area sensor 8 is sent to the control means 9, and when the signal is sent, the pallet unit is sent. The operation of 2 automatically stops and the alarm is activated to notify the operator of the danger.

Further, even after the lifting operation is completed, the area sensor 8 is operating unless the lid member 5 is closed and the lid opening / closing detection sensor 4 does not detect that the lid is closed. Even if the operator is not within the detection range of the area sensor 8 with the key inserted in the key switch 10, the signal from the area sensor 8 is transmitted to the control means 9 to activate the alarm device, The operator is informed that he has forgotten to pull out.

[Effect of device]

 In the parking device of the present invention described above, the lid opening / closing detection sensor is provided in the operation section, and by providing the detection sensor and the area sensor for detecting the state of the operator, the operation section is of course not operated. Even when the operation part is being operated, when an operator enters the lifting range of the pallet part, the pallet part is automatically lifted and stopped safely, and the alarm is activated. As a result, safety is ensured by making the operator aware of the danger.

Even after the end of the operation, the lid open / closed detection sensor is activated unless the lid member is closed, so that, for example, the area sensor detects with the key inserted in the key switch. When there is no operator within the range, the alarm is activated to notify the operator of forgetting to remove the key or forgetting to close the lid member, and a person other than the operator may open the lid member to mischief. It is possible to prevent things from happening.
