BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard having a variable operating surface height.

0002

2. Description of the Related Art Keyboards are used for operations such as controlling the operations of various control devices and inputting data. For example, in a series of processes such as mounting components on a printed wiring board, the mounting process is stored in the control device in advance, and the operator (operator) inputs necessary data and inputs various modes by operating the keyboard. Perform tasks such as setting.

0003

A keyboard for inputting data to a control device is usually placed, for example, on a base (desktop) in a factory. Therefore, the height of the keyboard operating surface is determined by the height of the base, that is, the height of the top surface of the base from the floor, and the operating surface is fixed at a constant height. By the way, a worker (keyboard operator) performs work by appropriately selecting a standing posture or a sitting posture depending on the work content or work environment. For this reason, when operating a keyboard that is placed on a base and has a fixed operating surface height, it is difficult to operate it in a seated position even if the operating surface height corresponds to the working condition in a standing position. On the other hand, when the operating surface height corresponds to the working condition in the seated position, there are disadvantages such as pain in operation in the standing position.

[0004] This invention solves the above-mentioned problems, and by making the height of the operating surface of the keyboard variable, a plurality of operating surface heights corresponding to different working postures such as standing up work and sitting work can be obtained. The purpose is to provide a keyboard that can.

[0005]

Means and Effects for Solving the Problems In order to achieve this object, the keyboard of the present invention has the following configuration. The keyboard includes a case body that includes a storage section within the surface and a locking hole provided at a suitable position on the outer circumferential surface of the storage section, and a rotatable link whose one end is pivoted to the side wall of the storage section of the case body. an arm, a support base plate fixed to the other end of the link arm, one end of which is pivotally supported on the upper surface of the support base plate, and a locking portion that engages and disengages from the locking receiving hole at the other end. It is characterized by consisting of a rotatable keyboard body.

[0006] In a keyboard having such a configuration,
It is usually placed on the table. When a worker (operator) performs an operation while sitting, for example, the support base is laid down in a direction perpendicular to the case body. In other words, the support base is held in a horizontal state. At this time, the link arm (the first joint arm on the storage part side and the second joint arm on the support base side are rotatably pivoted at the connecting part) projects outward from the storage part in a straight state. ing. Further, in this state, the keyboard body is in contact with the upper surface of the support base and is in a horizontal state. The height of the operating surface of this keyboard is optimal for an operator to operate the keyboard while seated. On the other hand, when the operator works in a standing position, the support base is rotated toward the case body. In other words, the support base is lifted from a horizontal position to a vertical direction. As a result, the link arm is rotationally displaced (the first joint arm is displaced toward the storage section, and the second joint arm is displaced to be in contact with the upper surface of the support base). Here, the keyboard whose tip end is hinged to the support base is rotated, and the locking portion (locking piece) at the other end of the keyboard is locked in the locking receiving hole of the case body. As a result, the keyboard body is placed in a substantially horizontal position on the upper side of the case body. The height of the operating surface of the keyboard body is optimal for an operator to operate the keyboard in a standing position.

[0007] Thus, the height of the operating surface of the keyboard can be arbitrarily varied between the working position and the standing position, thereby providing a keyboard that is easy to use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a specific embodiment of a keyboard according to the present invention.

[0009] The keyboard includes a storage section 11 within the plane,
A case body 1 in which a locking hole 12 is provided at a suitable position on the outer circumferential surface of a storage part 11, a rotatable link arm 2 whose one end is pivotally supported on the storage part side wall 11a of this case body 1, and this link arm. 2, one end of which is pivotally supported on the upper surface of the support base plate 3, and a locking portion 41 that engages and disengages from the locking hole 12 at the other end. It consists of a rotatable keyboard body 4 and a rotatable keyboard body 4.

The case body 1 is a rectangular flat plate having a constant thickness and a constant height, and a recess-shaped storage portion 11 having a predetermined depth is formed in the front surface of the flat plate. A locking receiving hole 12 is provided in the upper part of the outer circumferential surface of this storage portion 11. Furthermore, magnets 13 are attached to both sides of the outer peripheral surface of the storage portion 11, respectively.

The link arm 2 has one end connected to the storage section 11.
It is rotatably supported on a side wall 11a of the holder, and the other end is fixed to a support base plate 3, which will be described later. This link arm 2 is composed of a first joint arm 21 on the storage section 11 side and a second joint arm 22 on the support base plate 3 side. The first joint arm 21 and the second joint arm 22 are rotatably pivoted at the connecting portion 2a.

The support base plate 3 is a rectangular flat plate of approximately the same size as the case body 1, and one end (base end) is connected to the connecting portion 3.
1 and a hinge 32, it is rotatably attached to the case body 1. Further, a magnetic plate (iron plate) 33 corresponding to the magnet 13 of the case body 1 is attached to a suitable position on the upper surface of the support base plate 3. Further, on the upper surface of the support base plate 3, a keyboard main body 4 having a size that fits into the storage portion 11 is provided. The keyboard main body 4 is attached to the upper surface of the support base plate 3 via a hinge 42, with one end side (tip side) being the bottom surface. Furthermore, a locking portion (locking hook) 41 is provided on the other end (base end side) of the keyboard body 4 to protrude from the locking receiving hole 12 of the case body 1 . Furthermore, a handle (handle for grasping) 43 is provided at a suitable position on the upper surface of the keyboard main body 4, and an engagement receiving portion (receiving hole) 34 for maintaining the contacting state of the support base 3 is provided on the bottom surface on the base end side. An elastic protrusion 44 that corresponds to and is detachable is provided in a protruding manner.

[0013] A keyboard having such a configuration is normally placed on a tabletop (not shown). worker (operator)
However, when performing an operation in a seated posture, for example, as shown in FIG.
is laid down in a direction perpendicular to the case body 1. In other words,
Hold the support base 3 in a horizontal state. At this time, the first joint arm 21 and the second joint arm 22 of the link arm 2 are rotationally displaced and protrude outward from the storage portion 11 in a straight state. Furthermore,
In this state, the keyboard main body 4 is in contact with the upper surface of the support base 3 and is in a horizontal state. This keyboard body 4
The height of the operating surface is optimal for the operator to operate from a seated position. On the other hand, when the operator works in a standing position, the support base 3 is rotated toward the case body 1, as shown in FIG. That is, the support base 3 is lifted from a horizontal state to a vertical direction. As a result, the first articulated arm 21 is displaced toward the storage section 11 side, and the second articulated arm 22 is displaced to be in contact with the upper surface of the support base 3. Here, the keyboard body 4 is rotated using the hinge 42 as a fulcrum on the distal end side with respect to the support base 3, and the locking piece portion 41 of the keyboard body 4 is locked in the locking receiving hole 12 of the case body 1. As a result, the keyboard main body 4 is placed in a substantially horizontal state on the upper side of the case main body 1. The height of the operation surface of the keyboard body 4 is optimal for an operator to operate the keyboard in a standing position.

[0014] When not operating the keyboard, leave the keyboard body 4 in contact with the support base 3 (with the operating surface height for the sitting posture), and move the support base 3 along with the support base 3 to the case body 1 side. lift. At this time, the first section arm 21
The second joint arm 22 is in the overlapping state, and the keyboard main body 4 is completely accommodated in the storage portion 11. Furthermore, in this state, the outer circumferential surface of the support base 3 (the outer circumferential surface of the keyboard body 4) is in contact with the outer circumferential surface of the case body 1 (the outer circumferential surface of the accommodating portion 11), and the corresponding magnet 13 and magnetic plate 33 is fixed by suction. In addition, in this state, the supporting base 3 that is in contact with the
In the case body 4, the engaging portion 44 and the engaging receiving portion 34 engage with each other, preventing the keyboard body 4 from separating from the support base 3, and protruding forward from both sides of the case body 1. Both sides of the support base plate 3 are surrounded and supported by the surrounding walls 1a, thereby ensuring safety in the stored state.

[0015] Thus, the height of the operating surface of the keyboard can be arbitrarily varied between the working position and the standing position, thereby providing a keyboard that is easy to use.

In the embodiment, one locking receiving hole 12 is provided, but in practice, a plurality of locking receiving holes 12 may be provided in the vertical direction. By selecting the receiving hole 12 and hooking and locking the locking piece 41, the height of the keyboard operation surface can be more finely varied.

[0017]

Effects of the Invention As described above, in the present invention, a rotatable link is provided on the side wall of the storage portion of the case main body, which has a storage portion within the surface and a locking hole provided at an appropriate position on the outer circumferential surface of the storage portion. One end of the arm is pivotally supported, the other end of the link arm is fixed to the support base plate, one end is pivotally supported on the upper surface of the support base plate, and the other end is a lock that engages and disengages from the lock receiving hole. Since we decided to equip the keyboard with a rotatable keyboard body, the height of the keyboard operation surface can be changed arbitrarily, and multiple operation surface heights can be used to accommodate different working postures such as standing up and sitting work. It has the effect of achieving the purpose of the invention, such as being able to obtain
