Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide frame which is mounted on a floor of a vehicle and guides a movable frame to move toward and away from an opening of the vehicle. An elevating frame comprising: a pair of links interposed in a state forming a four-bar link mechanism between the movable frame and the elevating frame, and with the movement of the movable frame in the perspective direction with respect to the opening. The lifting frame is raised or lowered in a parallel or substantially parallel posture in a lowered state in which the mounting portion is lowered on or near the ground and in a raised state in which the mounting portion is raised to the same height or substantially the same height as the floor surface of the vehicle. Thus, a regulating mechanism that regulates the posture of the pair of links and a moving operation mechanism that is disposed along a perspective direction with respect to the opening in order to move the movable frame along the guide frame are provided. Related to a vehicle elevating device.

[0002]

2. Description of the Related Art Such a vehicle elevating device is, for example,
With the user sitting on the wheelchair as the object to be mounted, place the wheelchair on the mounting part, raise and lower the lifting frame with the moving operation of the movable frame by the moving operation mechanism, and place the wheelchair on the ground. It is used for transferring from the side to the floor of the vehicle, transferring from the floor of the vehicle to the ground, and the like.

Conventionally, a pair of guide frames each having a U-shaped cross section are provided as such a lifting device, and the pair of guide frames is provided with U-shaped openings facing each other. In each of the U-shaped guide frames, a screw rod as the moving operation mechanism and a nut member screwed to the screw rod are disposed, and the screw rod is rotated in the forward and reverse directions. It is known that the movable frame moves in a U-shaped guide frame with driving, and a pair of links move in and out of the guide frame (for example, See JP-A-10-217829).

[0004]

However, in the above-mentioned prior art, the pair of guide frames have a U-shaped cross section and their openings face each other, that is, the openings face inward. Due to the provision, the screw rod and the nut member constituting the moving operation mechanism are located adjacent to the opening facing inward, and the user's hand or clothes may come into contact with the screw rod or the like. There is. Normally, oil such as grease is applied to such a screw rod or a nut member for smoothness. Therefore, when a user's hand or clothing comes in contact with the oil, the clothing or the like is stained by the oil. There was a disadvantage. Similarly, the movable frame or link to which oils may be attached is also located adjacent to the opening of the guide frame having a U-shaped cross section, so that the movable frame or link can also reduce hand or clothing. There was a risk of being soiled.

The present invention has been made to overcome the above-mentioned drawbacks. The object of the present invention is to solve the problem that even if oil is applied to a moving operation mechanism or the like, the user's hands or clothes are not affected by the oil. It is an object of the present invention to provide a vehicle elevating device that is less likely to be soiled.

[0006]

According to the first aspect of the present invention, at least a part of a guide frame for moving and guiding a movable frame is formed in a cylindrical shape. Since the moving operation mechanism for moving the movable frame along the guide frame is provided in the cylindrical guide frame, there is a possibility that the user's hand or clothing may come into contact with the moving operation mechanism. Therefore, even if oil such as grease is applied to the moving operation mechanism, there is little risk that the oil or the like will stain hands or clothes. Further, the movable frame is configured to move within the cylindrical guide frame, and the pair of links are configured to move back and forth with respect to the cylindrical guide frame. There is little possibility that the hand or clothes of the person will come into contact with the movable frame or link,
Even if oils are attached to the movable frame, the link, etc., there is little risk that the oils will stain clothes and the like.

According to the second aspect of the present invention, the moving operation mechanism includes a screw rod that is driven to rotate in the forward and reverse directions, and a nut member that is screwed to the screw rod and fixed to the movable frame. Therefore, it is possible to raise and lower the lifting frame and the mounting portion reliably while the moving operation mechanism has a relatively simple structure. In other words, this kind of moving operation mechanism can be configured using, for example, an endless chain, but in that case, a driving sprocket or a free-wheeling sprocket is required, and the number of parts is large and the structure is large. Is complicated. On the other hand, if a screw rod and a nut member are used, the number of parts is smaller and the structure is simpler than using an endless chain, and the lifting operation of the lifting frame and the mounting portion can be performed as desired. it can.

According to the third aspect of the present invention, since each of the guide frame, the movable frame, the pair of links, and the moving operation mechanism is provided in a pair, one guide frame, the movable frame and the like are provided. In this case, the lifting frame and the mounting table can be moved up and down more stably than when the lifting frame is cantilevered in a cantilever manner.
It is configured by a guide member having a U-shaped cross section having an opening on the side facing each other and having a guide portion for guiding the movable frame, and a closing member for closing the opening of each guide member. Therefore, the manufacture of the guide frame is easy, and the assembling of the moving operation mechanism with respect to the guide frame is also easy. In other words, in order to form the guide frame into a cylindrical shape, it is possible to form the guide frame integrally by a drawing process or the like. However, in that case, the drawing process itself becomes complicated and The work of assembling the moving operation mechanism and the movable frame becomes complicated. In that regard, if the guide member is formed of a U-shaped guide member and a closing member, the formation of the guide member is relatively easy, and after the moving operation mechanism and the movable frame are assembled to the guide member, the closing member is used. Since the U-shaped opening can be closed, assembling work such as a moving operation mechanism is facilitated, and the closing member for closing the opening reinforces the U-shaped cross section guide member. Therefore, the rigidity of the guide frame is also improved.

According to the fourth aspect of the present invention, the mounting portion is configured to be slidable with respect to the lifting frame along the direction closer to and away from the opening. When the object is slid in a direction away from the opening while being raised to the same height or substantially the same height as the floor, the object to be mounted on the mounting part can be easily moved to the back of the vehicle. A guide for sliding is provided on the mounting portion, and when the mounting portion slides in the raised state, the guide is configured to contact the outer surface of the guide frame and be guided. Therefore, the slide movement of the mounting portion can be performed stably.

According to the fifth aspect of the present invention, since the mounting portion is configured to be slidable with respect to the lifting frame along the perspective direction with respect to the opening, as described above, the mounted object is provided. Is configured to be able to be easily moved to the back of the vehicle, and that a guided member for sliding provided on the mounting portion is guided in contact with an outer surface of a closing member constituting a guide frame. Therefore, the guide function of the mounting portion can also be performed by the above-described closing member.
