Description

  The present invention relates to a clip mechanism for fixing a small electronic device in which an electronic component or the like is housed in a box to clothes.

For example, a small electronic device having a gas sensor needs to be exposed on the surface of clothes because of the gas taken into the sensor.
For this reason, a structure is adopted in which the clip is fixed to the box and fixed to the clothes with the clip. For example, in a small electronic device having a display for display, depending on the attachment position to the clothes, the top and bottom are reversed. Sometimes it is easier to see the display.

  The present invention has been made in view of such circumstances, and its purpose is to set the relative angle between the clip mechanism and the small electronic device to an arbitrary position and to prevent a small amount of external force. To provide a clip mechanism capable of maintaining a set relative angle.

  In order to achieve such a problem, in the present invention, a base that can be pivotally attached to a member to be attached, a lever that is pivotally attached to the base, and a base and a lever. The locking plate is located between and is opened and closed by the rotation of the lever. The locking plate has a locking portion at one end, and the other end protrudes from the base and is elastic to the mounted member. A tip portion is formed, and the tip portion is configured to elastically contact the attached member in a state where the lever is tilted and the locking portion comes into contact with the base.

  According to the first aspect of the present invention, when the position relative to the electronic device is set in advance in a state that is fixed to the clothing or the like, the leading end of the locking plate elastically contacts the surface of the attached member, and generates a strong frictional force. Free rotation is prevented.

  FIG. 1 shows an embodiment of a clip mechanism according to the present invention. The clip mechanism 1 includes a base 10, a locking plate 20, and a lever 30 that are rotatably attached to a member 40. It is comprised by one member.

  The base 10 is made of a plate material as shown in FIGS. 2 (a) to 2 (c). Specifically, a mounting hole 12 for attaching a member to be attached is formed in the main body 11; Side walls 13 and 13 are formed on both sides by bending substantially at right angles, and through holes 14 and 14 for supporting a shaft portion 33 of a lever 30 (to be described later) on the side walls 13 and 13 at positions away from the mounting holes 12 are relative to each other. An abutment portion 15 that is formed at a position facing the front end of the engagement plate 20 and is slightly bent at a distal end side of the engagement plate 20, that is, a position opposite to the engagement portion; The long hole 16 into which the 20 engagement convex portions 21 are inserted is formed.

  As shown in FIGS. 3 (a) to 3 (c), the locking plate 20 is formed by shaping an elastic material into a substantially "<" shape. 10 to be in contact with the long hole 16 of the base 10 so as to abut on the abutment portion 15 of the base 10, and convex portions 22 and 22 that elastically contact the side wall portions 13 and 13 on both sides slightly retracted. A wavy engagement portion 23 is formed at the rear end so as to securely lock clothes and the like.

  The protruding portion 21 protrudes from the long hole 16 of the base 10, and in a state where the locking plate 20 is pressed by the lever 30, the tip 21 a moves to the mounted member material side from the base and the mounted member The length is adjusted so that it may elastically contact the surface of the wall surface 40a which comprises a material.

  As shown in FIGS. 4 (a) to 4 (c), the lever 30 is bent at a substantially right angle with a relatively high plate material, and the peripheral surface on the side that becomes the operation portion 31 is bent to provide rigidity. A convex portion serving as a shaft portion 33 that is rotatably inserted into the through-holes 14 and 14 is formed on the side portion of the pushing portion 32 that is bent substantially perpendicularly with respect to 31.

  The push-in portion 32 is formed so that the tip thereof slightly protrudes from the shaft portions 33, 33, and can reliably hold down the locking plate 20 while reducing friction with the locking plate 20 as much as possible. It is configured as follows.

  Each of the members 10, 20, 30 configured in this way is inserted into the long hole 16 at the tip of the base 10 through the convex portion 21 of the locking plate 20, and then the shaft 30 so that the lever 30 overlaps thereon. The parts 33 and 33 are inserted into the through hole 14 of the base 10.

  As a result, the locking plate 20 has its convex portion 21 restricted by the long hole 16 of the base 10 and the convex portions 22 and 22 restricted by the side wall portions 13 and 13 of the base 10, and the upper and lower sides thereof. It is regulated by the lever 30 and is in a state where only rotation with the tip side as a fulcrum is possible.

  When the lever 30 is opened as shown in FIG. 1 (a), the pushing portion 32 of the lever 30 rises with respect to the base 10, so that the locking plate 20 is engaged on the rear end side with the front end side as the center. Since the part 23 is lifted from the base 10 and a gap is formed, clothes, a belt or the like is inserted into the gap.

  Next, when the operating portion 31 of the lever 30 is rotated to the base side as shown in FIG. 1B, the pushing portion 32 at the tip of the lever 30 is rotated so as to push the locking plate 20 toward the base 10 side. The rotation stops at a position that is substantially vertical, that is, a position where the tip of the pushing portion 32 includes a line connecting the through holes 14 and 14 and is included in a plane perpendicular to the base 10. Thereby, the locking plate 20 brings the engaging portion 23 into elastic contact with the base 10 by its own elasticity.

  Needless to say, the pushing portion 32 of the lever 30 receives the elastic force from the locking plate 20 and presses the shaft portions 22 and 22 to the upper side of the through hole 14, so that the lever 30 is fixed at a predetermined position. The

  In this state, the distal end portion 21a of the locking plate 20 protruding from the base 10 is elastically contacted with the surface of the mounted member to generate a strong frictional force between them, and is also rotated by an external force applied to the mounted member. Prevent movement as much as possible.

  When the clip mechanism is removed from the clothes, since the lever 30 is caused by inserting a nail into the gap between the operating portion 31 of the lever 30 and the locking plate 20, the state shown in FIG. be able to.

  FIG. 5 shows an example of a small electronic device that is an attached member 40 suitable for the clip mechanism 1 of the present invention, and is a box 42 having a flat portion at least on a surface 41 to which the clip mechanism 1 is attached. In this example, a gas sensor 44 and a display 45 are provided on the opposite surface 43 to constitute a portable gas detector.

  The attachment hole 12 of the clip mechanism 1 described above is preferably circular, and can be pivoted around the attachment hole 12 by the eyelet 46, and attached with a clamping force that causes the clip mechanism 1 to stop at a predetermined angle by friction. When attached, the relative angle with the clip mechanism 1 is adjusted so that the characters on the display 45 are easy to see, and are fixed by the lever 30.

As a result, the engagement portion 23 of the locking plate 20 is fixed between the base 10 and the clothes.
In this state, as described above, the distal end portion 21a of the locking plate 20 is elastically contacted with the surface 40a of the mounted member to generate a strong frictional force between them, and is also rotated by an external force applied to the mounted member. The relative angle between the mounted member 40 and the clip mechanism 1 is kept constant by preventing the movement as much as possible.

  In the above-described embodiment, the clip mechanism 1 is directly attached to the attached member 40, but a latch mechanism 50 is interposed between the clip mechanism 1 and the attached member 40 as shown in FIG. Thus, the clip mechanism 1 can be pivotably attached.

  Such a latch mechanism 50 is laminated so as to be relatively rotatable. The two plate members 51 and 52 and a ball holding hole are formed on the upper surface of one plate member (lower plate) 51 to hold the ball 53 here. The other plate member (upper plate) 52 is made of an elastically deformable material, and a recess is formed on the circumference where the ball 53 can be fitted at a predetermined interval. What is configured is optimal.

  According to this embodiment, first, the relative angle between the clip mechanism 1 and the attached member 40 is positioned by the latch mechanism 50, and when the clip mechanism 1 is fixed to clothes or the like in this state, the upper plate 52 of the latch mechanism is locked. Since it is pressed and elastically deformed by the tip portion 21a of the plate 20, a strong pressure acts between the plate members 51 and 52, and it is impossible to get over the ball 53 and is fixed.

  In the above-described embodiment, the latch mechanism is configured as a single member, but one plate member (lower plate) 51 may be configured using the wall surface 40a of the case serving as a mounting member member. Has the effect of.

  Each member is preferably made of sheet metal or the like, but it is clear that the same effect can be obtained even if it is made by injection molding of a polymer material having relatively high rigidity.
