Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a set leg device that can be used in ultra-small image display devices using liquid crystals or the like.

2. Description of the Related Art In recent years, small-sized image display devices using means such as liquid crystals have been widely used. Such devices are configured so that the elevation angle of the device can be set in various ways depending on the usage situation in order to make images easier to see (for example, Utility Model Publication No. 57-427).
(Japanese Utility Model Application No. 69-82277).

A conventional set leg device will be described below.

FIGS. 8 and 9 show a conventional set leg device. In FIG. 8, 101 is a display housing, 103 is a display window, 105 is a support portion, and 106 is a shaft support. In this device, the display window is rotated about a shaft support 106 in order to set the angle of the display window surface.

Figure 9 shows an example of an electronic desktop calculator, where a is an overall view, b is a view with a large elevation angle, and C is a side view with a small elevation angle. 02Q1 is a hard case that can also be used as a set leg, and 203 is a plug-in case. , 2o4 represents the pocket, and 205 represents the main body. In order to set the elevation angle of the display surface to two types, the hard case 201 is provided with a bending part, and by changing the direction of insertion into the shank 204, the elevation angles shown in Figures b and 0 are set.

Problems to be Solved by the Invention However, in the case of the one shown in FIG. 8, the entire supporting part housing 101 is lifted by the supporting part 105, which makes the entire device large-scale. Since the support 106 also needs to be strong, it is difficult to avoid an increase in size and weight, making it unsuitable for small-sized image display devices.

In addition, in the configuration shown in Figure 9, the set legs are also used as the case, so they are useless when the main body is removed from the case, and even if they are attached to the set as dedicated set legs, the material If the case is made of leather, vinyl chloride sheet, etc., the main body that can be supported is limited to an extremely lightweight one, and the setting angle is also extremely rough.The point is that it varies from product to product and changes over time. It was extremely unreliable.

In view of the above problems, the present invention is small and simple, yet has two
The purpose of the present invention is to provide a set leg device that can accurately set various angles.

Means for Solving the Problems In order to solve the above problems, the set leg device of the present invention includes a first member having a rotation center on the rear side of the set, and a second member slidably supported by this member. The first member is biased by a spring force and exhibits overall movement in the direction of opening the set leg at all times, and has a protrusion and a perforation for setting two types of positions. It is something.

Function: With the above-described configuration, the present invention allows two types of setting angles to be reliably set without compromising compactness during storage.

EXAMPLE Hereinafter, a set leg device according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the overall configuration of a set leg device in an embodiment of the present invention. In Fig. 1, numeral 1 denotes a set base body, which has a substantially box-like shape by being made entirely of metal from a thin plate. Reference numeral 2 designates a guide portion which is a part of the main body and bends the U-shaped bent end portion further inward to guide the sliding of the set leg sub body end portion, which will be described later. 3 and 4 are holes drilled on both sides of the set base body, 5 is a sub body part of the set leg, one end is the rotation center and is supported for rotation by the bin 8 on the back of the set, and the other end is the center of rotation. The cylindrical parts 6 attached to both sides of the part slide along the inside of the guide part 2 of the set script body mentioned above. or,
Protrusions 7 are provided on both sides of the center part, and are engaged with the perforations 3.4 of the set base body when storing and setting the set angle, respectively. Also, there is a spring locking hole 9 in the center part, and a spring 10 locks the set bottom surface. It is constantly biased towards the side. Reference numeral 12 denotes a set leg holder provided on the rear side of the set, into which a set leg fitting part 13 and a spring locking hole 11 are biased. 14
is the bottom of the set leg and is fitted into the fitting part 13. 16 is a stopper of the guide portion. 16 represents a set.

The operation of the set leg device configured as described above will be described below with reference to FIGS. 1 to 7.

As shown by the arrow in FIG. 1, insert the cylindrical part 6 of the set leg sub body into the guide part 2 of the set leg 1, fit the set leg bottom part 14 into the fitting part 13 on the back of the set, and set the set leg 1 at 16. When pressed against the back of the set leg, the set leg will be stored.

The state of engagement between the cylindrical portion 6 and the guide portion 2 at this time is shown in FIG.

FIG. 3 is a sectional view showing the above-mentioned storage state, in which the perforation 4 of the set leg 1 and the protrusion 7 are engaged, and the cylindrical part 6 and the guide part 2 are engaged with each other.
are engaged, and the set leg 1 and the set leg subsidiary body 6 are integrated, and the set leg subsidiary body is urged toward the set leg holder by the spring 1o. As a result, the entire set leg is fixed to the back of the set.

FIG. 4 shows a state in which the upper end of the set leg 1 is pulled up as shown by the arrow from the state shown in FIG. 3 to release the engagement between the perforation 4 and the protrusion 7. At the same time as the setting leg sub-body is released, it rotates in the direction of the arrow due to the spring force, and the cylindrical part 6 slides downward along the guide 2. Eventually, the cylindrical part 6 comes into contact with the stopper 16, and the sub-body 5 is rotated. Rotation stops. This state is shown in FIG. 6, where the set leg is set on a plane with the back side. In this state, the biasing force of the spring 1o dominates the link mechanism that constitutes the whole, and the spring 1o is not deflected by the set's own weight, but even if the top of the set is pressed by mistake, it will simply
(The screw 1o just stretches and returns immediately when the stress is removed, which has the advantage of not causing damage to the set leg.) Lift the set leg 1 from the state shown in Fig. 5 and remove the leg bottom 14 from the fitting part 13. Figure 6 shows a state in which the set leg is rotated while the cylindrical part 6 is in contact with the stopper 16.The set leg is rotated in the direction of the arrow in Figure 6 to complete the drilling 3.
When the protrusion 7 is engaged, the set leg 1 and the secondary body 5 become one, and the secondary body 6 is rotated by the spring 1° to a stopper (not shown) provided on the rotation support part, and is rotated at a constant angle. Fixed. This state is shown in Fig. 7.0 As described above, by the series of operations from Fig. 3 to Fig. 7, the set leg is retracted as shown in Fig. 3, the low elevation angle is set as shown in Fig. 6, and the set leg is set as shown in Fig. 7. A high elevation angle setting such as this can be achieved using only the same member, and the angle can be set reliably.

Note that if the set leg 1 is rotated clockwise relative to the secondary body 6 from the state shown in FIG. Fifth
This is the state shown in the figure, and if the set leg 1 is further pressed against the rear side of the set from this state, the state returns to the state shown in FIG. 3.

Effects of the Invention As described above, according to the present invention, a sub-body that is biased by the paneka and rotates around the back of the set, and a set leg that slides on the rotating tip of the sub-body are provided on each side. By engaging the projection with the perforation, it is possible to reliably and quickly set two types of elevation angles, and it is also possible to make it very compact when stored.
