Abstract

PURPOSE:To simplify the titled mechanism by locking the 1st and 2nd leg parts downward respectively and therefore supporting the positions of these leg parts at different angles. CONSTITUTION:A rotary leg 1 of a support leg for keyboard has a plate form as a whole with the 1st short leg part 11 set on a single side of the leg 1 together with the 2nd long leg part 12 set vertically respectively. A rotary shaft 13 protruded at both sides is set at an intersecting point between both leg 11 and 12 in the supporting direction. The shaft 13 is supported by a bearing part 22 at an opening part 21 of a lower cabinet 2, and an elastic tongue part 23 is extended from the opening 21 above the shaft 13. Then the leg 1 is put through a notch 24 in an assembling mode, and the shaft 13 is put on the part 22 and held by a pivot 31. Then the part 11 or 12 is protruded over the lower surface of the cabinet 2 by the revolutions of the leg 1. Thus both parts 11 and 12 can support a keyboard at different levels respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support leg mechanism used for mounting a keyboard of a so-called microcomputer or the like.

[Prior Art] In keyboard devices such as the Wayuru microcomputer, it is required that the angle of the surface on which the keys are arranged can be changed depending on the usage situation. Examples of support leg mechanisms that can change the angle include Japanese Utility Model Publication No. 55-2632 (Reference 1) and Japanese Utility Model Publication No. 55-2632 (Reference 1).
A mechanism disclosed in Publication No. 1-55206 (Document 2) is known. That is, in the mechanism of Document 1, a recess for housing the leg is provided at the bottom of the device main body, the leg is rotatably installed in the recess, and when the leg is pulled out, the main body abuts a part of the leg. A first protrusion is provided in a portion of the recess to increase the distance between the support part of the leg and the contact part, and the bottom surface of the recess is configured to hold the leg between the first protrusion and the first protrusion. second to
It has a protrusion formed on it. Further, the mechanism of Document 2 supports a support leg consisting of a head having a cam surface around it and a leg connected to the head so as to be rotatable around the head, and the leg protrudes from a through hole formed in the bottom plate of the cabinet, and the cam surface formed in the head is brought into contact with a sliding body biased in a certain direction by a spring, and the pressing force of the sliding body is applied. The support leg is configured to rotate with a click action.

[Problem that the invention seeks to solve]

Conventionally, the above-mentioned mechanism has been known. However, in each case, the above-mentioned mechanisms have problems such as a complicated structure of protrusions and the like, and an increase in the number of parts such as springs.

[Means for solving problems]

The present invention provides a rotating leg (1) having first and second legs aυ, (121) having different lengths at a predetermined angle with respect to the rotating axis α3, and a shaft support for the rotating axis a3. a lower cabinet (2) having a tongue part (2) that elastically locks the rotating leg (1); and a lower cabinet (2) that locks the rotating shaft (131) corresponding to the information receiving part Q2; This is a support leg mechanism for a keyboard consisting of an upper cabinet (3) having a pivot Gυ.

[Effect]

In the above mechanism, the pivot leg (1) is connected to the first leg (11
1 facing downwards or the second leg (121 facing downwards) to support the device at different angles.In this case, the mechanism is It is formed of only three parts: the rotating leg (11), the lower cabinet (2), and the upper cabinet (3), and can be realized with an extremely simple configuration.

〔Example〕

FIG. 1 is a perspective view of the main parts of the mechanism, and FIGS. 2 to 4 are arbitrary sectional views. In these figures, (1
) is a rotating leg, and this rotating leg (1) has a plate shape as a whole, and has a short first leg αB formed on its negative side, and a long second leg αB in the vertical direction. The leg of the eel is considered to be the eel. A rotation shaft Q3 is provided at the intersection of the support direction (dotted chain line) of these legs αn, 121 and protrudes from both sides.

Further, the distances from the rotation axis (131) to the opposite surface I of the first leg αB and the opposite end ■ of the second leg (12+) are made approximately equal, and these surfaces α and the end The portion α9 is formed into a flat surface.

Further, (2) indicates a lower cabinet, and this lower cabinet (2) is provided with an opening (211) having a width approximately equal to the width of the rotating leg (1), and a rotating axis 0 on both sides of this opening (2υ). A shaft bearing (2z) is provided for the opening I.
A tongue portion (
c) will be provided. Only one end of this tongue part (end) is connected to one end of the opening Qυ, so that the whole part has elasticity, and furthermore, its tip (other end) part rotates through the distance near the shaft bearing part (22). From the axis (131 to the plane (141 and the end')
151 is formed to be slightly smaller than the distance to 151. Furthermore, a notch I24J through which the rotation shaft (13) protrudes on both sides is provided between the shaft bearing part @ of the opening Qυ and one end where the tongue part (c) is provided.

Further, an upper cabinet (3) (not shown) (a bidet to be installed) C3υ is arranged so as to come into contact with the rotation shaft (131) from the extension direction of the support direction of each leg part (U1, +121).

In this mechanism, when assembling, insert the rotating leg (1) through the notch (2) and insert the rotating shaft (131) above the opening Qv, move it along the lower surface of the tongue (C), and move the rotating leg (1) to the shaft bearing part C.
! Place it on the table. Thereafter, by attaching the upper cabinet (3), the rotation shaft U is held between the shaft bearing part (221) and the pivot C311.

Therefore, in this mechanism, by making the first leg part 011 or the second leg part f+21 protrude from the lower surface of the lower cabinet (2) by rotating the rotating leg (1), it is possible to set the first leg part 011 or the second leg part f+21 to different heights. support. This allows the angle of the device to be changed as shown in FIGS. 5A and 5B. In the case of a keyboard device, the upper cabinet (3)
The upper surface of the device is formed in advance at a predetermined angle, and the angle is further changed by the mechanism described above.

In the above mechanism, the rotating leg (1) has its surface (14) or end α9 at each rotating position.
It is fixed against the When setting and rotating, the tongue (
Rotation is possible due to the elasticity of c). Furthermore, a pivot 01) is provided in the extending direction of the supporting direction at each rotating position, and the pressure applied to each leg aυ, αZK is transmitted to the upper cabinet (3) via this pivot (c31). Ru. This prevents unnecessary force from being applied to the lower cabinet (2).

Further, according to the above-mentioned mechanism, it is formed of only three parts: the rotating leg (1), the lower cabinet (2), and the upper cabinet (3), and can be realized with an extremely simple configuration, and furthermore, it is extremely easy to assemble. Further, as is clear from the figure, the lower cabinet (2) has a shape that can be easily manufactured by integral molding.

〔Effect of the invention〕

According to the present invention, the devices are supported at different angles, the mechanism thereof is formed with an extremely simple structure, and furthermore, the assembly can be performed extremely easily.
