Description

A parallelogram 4-section linkage with adjustable length and a cup holder-mounted multipurpose cradle device using the same

The present invention makes it possible to add the function of adjusting the length in addition to the characteristics of the parallelogram 4-bar link, and by using this, the height, distance and angle adjustment between the position desired by the driver or passenger in the passenger seat from the position of the cup holder in the vehicle It relates to a parallelogram quadrilateral link device capable of adjusting the length so that it can freely mount a holder or table for beverage containers, and a cup holder-mounted multi-purpose cradle device for a vehicle using the same.

A general four-section link device consists of four links (or bars), and four contacts are connected by link pins, and each link forms a closed link structure that rotates on a plane based on the link pin of the contact.

Among these four-bar link devices, the parallelogram quadrilateral link device has two opposite sides ((a) and (c), (b) and (d)) as shown in FIG. 1A, Two opposite sides ((a) and (c), (b) and (d)) are parallel to each other.

For example, if a force is applied in the direction of the arrow (F) to the other side ((b)) connected with the link pin (l/p) in a state where one side (a) of FIG. 1a is fixed to be maintained horizontally, , one side ((b)) receiving the force and the other side facing it ((d)) are kept parallel to each other around the fixed side (a) and the link pin (l/p) connected respectively. Rotate at the same angle at the same time.

That is, the side (a) fixed in the above process and the side opposite to it ((C)) remain parallel to each other, and the opposite side (c) turns based on the fixed side (a)) make a relationship

Figure 1b shows the operation relationship of the four-section linkage applying the above characteristics, and in a state in which the pillar is erected vertically with respect to the standard, a predetermined height section among the pillars is fixed as one. Set as a link ((a)), and make the length of the two sides ((b), (d)) connected with each link pin (l/p) the same for this fixed link ((a)), Among the structures erected vertically at the ends of these two sides ((b), (d)), when connecting with link pins (l/p) for the same interval as the fixed link ((a)), the structure ( structure) always maintains a vertical state in response to the rotation of the two sides ((b), (d)).

In addition, when a table is installed horizontally with respect to a structure that maintains a vertical state, the table is positioned regardless of the change in position due to the rotation of the two sides ((b), (d)). keep it level

Here, the change of the rotation position of the above-mentioned table is limited to the turning line along the straight length of the two sides (b) and (d) with respect to the fixed link (a), which is a reference.

That is, according to the structure of the four-bar linkage device described above, the turning interval of the other side (c) parallel to the fixed link (a) from the position of the fixed link (a), which is the reference, is inevitably constant. .

On the other hand, when it is desired to increase the radius of the turning line, as shown in FIG. 2A , a pair of sides (a) and (c) facing each other is called a minor axis, and the other pair of adjacent sides facing each other is called a minor axis. When the sides ((b) and (d)) are referred to as major axes, the other pair of sides ((b) and (d)) forming the major axis is the side (g/r) forming the guide rail (g/r) in the longitudinal direction. (b') and (d')) and another pair of link pins (l/p) connected with link pins (l/p) so that link pins (l/p) are slidably connected along guide rails (g/r). It can be composed by connecting the sides ((b") and (d")).

With respect to this structure, as shown in Fig. 2a, another pair of sides ((b") and (d") centering on the part connected by the fixed side (a) and the link pin (l/p) )), adding another pair of edges ((b") and ( d")), the link pin (l/p) connecting them slides along the guide rail (g/r), and at this time, the fixed side (a) and the opposite side (c)) are, Including the change state of FIG. 2A, the parallelism with each other is disturbed.

For this reason, the conventional method for adjusting the turning interval is, as shown in FIG. 2b, a section of the parallelogram 4-bar linkage bracket and the structure at the same interval, each of which is set as one link. It adopts a structure that allows a change in the turning interval (f(d)~f(d')) by connecting it with a joint between two link groups.

However, the structure of FIG. 2b is limited according to the change in the position of the joint part, and in addition, it is necessary to enable more various adjustment of the turning interval.
