Abstract

(57) [Summary] [Purpose] To improve the workability of attaching / detaching the handle lock member. [Structure] In the handle lock member 4, the handle 2
Both sides 4a, 4b having press-fitting portions 4c, 4d of the handle 2 facing each other in the same direction as the rotation direction of the handle 2 and facing at a right angle thereto.
Is bent outward and the curved portion is pressed to widen the gap between the press-fitting portions 4c and 4d. [Effect] The load at the time of attaching and detaching the handle lock member is reduced, and erroneous operation at the time of detachment is eliminated, and high quality is obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handle lock device capable of locking the handle of a switch in an ON or OFF state.

[0002]

[Prior Art]

 FIGS. 4 and 5 are views showing a conventional handle lock device disclosed in, for example, Japanese Utility Model Laid-Open No. 103503/1993, in which 1 is a switch, 2 is a handle of the switch 1, and 3 is a handle 2 turned on or It is a handle lock member that locks in the OFF state, and has four opposite side portions 3a, 3b, 3c, 3d into which the four faces 2a, 2b, 2c, 2d of the protruding portion of the handle 2 are press fitted. The handle lock member 3 is best made of synthetic resin such as nylon, but is not limited to this.

Next, the operation will be described. When the handle 2 projected from the switch 1 is in the ON or OFF state, the handle lock member 3 is inserted from the upper diagonal direction of the handle 2. At this time, the relationship between the four surfaces 2a to 2d of the handle 2 and the four side portions 3a to 3d of the handle lock member 3 is regulated dimensionally and elastically pressure-bonded.

[0004]

[Problems to be solved by the device]

 Since the conventional handle lock device for a switch has the above-described structure, the disengagement load must be increased to satisfy the lock function of the handle lock member 3, but the mounting load is also increased accordingly. There was a problem that In addition, there is also a problem that the switch 1 malfunctions when the handle lock member 3 is detached because the detachment load is heavy.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a handle lock device for a switch which can be easily mounted with one touch and which can sufficiently satisfy a lock function. And

[0006]

[Means for Solving the Problems]

 The handlebar lock device of the switch according to the present invention is one in which both sides of the handlebar lock member are curved outward and the curved portion is pressed to form the handle insertion port.

[0007]

[Action]

 In this invention, the handle insertion opening is formed by pressing the curved portions on both sides of the handle lock member so as to widen the space between the two opposite sides facing each other in the perpendicular direction.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view showing a state before the handle lock member is attached, FIG. 2 is a top view showing the handle lock member of FIG. 1, and FIG. 3 is a top view showing the attached state of the handle lock member. The same or corresponding parts as the conventional ones are designated by the same reference numerals and the description thereof will be omitted. In the figure, 4 is a handle lock member, and both side portions 4a, 4b facing each other in a direction orthogonal to the turning direction of the handle 2 are outwardly curved, and both side portions 4c, 4d facing each other at a right angle thereto. Constitutes the press-fitting part. Reference numeral 4e constitutes a blocking portion that blocks the opening and closing of the handle 2.

Next, the operation will be described. Although the handle lock member 4 is inserted from the upper oblique direction, the dimension L of the press-fitting portions 4c, 4d of the handle lock member 4 into which the insertion surfaces 2c, 2d of the handle 2 are inserted has a press-fitting relationship as in the conventional case. That is, by pressing both side portions 4a and 4b of the handle lock member 4 at the time of insertion, the space between the press-fitting portions 4c and 4d facing each other at a right angle is widened by A as shown in FIG. 3, and the handle 2 can be easily inserted. You can When the both side portions 4a and 4b are separated, the same dimensional relationship as when press-fitting can be maintained. When detached, it can be easily removed by the reverse action.

In the above-mentioned embodiment, the one used for the single pole switch is shown, but it can be applied to the one used in parallel with two or three, and the same effect as the above-mentioned embodiment can be obtained.

[0011]

[Effect of the device]

 As described above, according to the present invention, the insertion opening is widened by bending both sides of the handle lock member and pressing the handle lock member to reduce the load at the time of attachment / detachment and eliminate the erroneous operation at the time of detachment, resulting in high quality. The effect of being obtained is obtained.

Claims (1)

[Scope of utility model registration request] 1. A handle lock member is attached to a substantially prismatic handle that opens and closes an electric path by being projected from one surface of a switch and rotated left and right to lock the rotation of the handle. In a handle lock device for a switch, both sides of the handle lock member facing each other in a direction orthogonal to a handle rotation direction are outwardly curved, and the curved portion is pressed to form an insertion opening of the handle. A handle lock device for a switch characterized by the above.
