Description

[Detailed description of the invention] This invention relates to an attachment for electric hair clippers.

Conventionally, when hair is styled using electric clippers, an attachment with comb teeth is detachably attached to the electric clipper, and the distance between the comb teeth and the shearing blade of the electric clipper is set appropriately to achieve a desired cutting height. is being carried out.

Then, to set the hair cutting height to an arbitrary value,
Generally, after an attachment is attached to a 11E hair clipper, the attachment is slid in a direction in which the distance between the shearing blades and the comb teeth changes and is fixed at an arbitrary fixed position.

For this reason, electric hair clippers and attachments are provided with engaging parts that can be slid in the direction in which the spacing between the shearing blades and the comb teeth changes, and that can be fixed at any position. The fixing operation at a desired position is performed together with the engaging/disengaging operation of the engaging part using a push button, etc., but the conventional method has a large number of parts and a complicated structure, and moreover, it is difficult to slide the attachment. It is troublesome to operate when attaching or removing.

This idea was developed in view of these points, and has an extremely simple structure that makes it easy to remove the attachment and slide it to any fixed position, and moreover, it can reliably prevent the attachment from moving during hair styling. The purpose is to obtain an attachment for electric hair clippers.

In this invention, the attachment is formed in a semicircular shape on the lower surface of the clipper body, and retaining parts are formed that elastically engage with both sides of the clipper body and both side edges of the attachment, and the attachment part is formed inside the clipper body. By forming a pair of left and right guide ribs on the circumferential surface, when the attachment is attached to the clipper body, the apex of the guide rib joins to the outer circumferential surface of the clipper body, stabilizing the installation state of the attachment, and the pressing part of the attachment is attached to the clipper body. By pressing the guide rib toward the main body side and sliding it in both directions of the clipper main body while joining the apex of the guide rib to the outer circumferential surface of the clipper main body, both side edges of the attachment widen in the expanding direction and the engagement portion is disengaged. The attachment is constructed so that it can be easily removed and slid to any fixed position.

An embodiment of this invention will be described based on the drawings.

First, at the tip of the hair clipper body 1, there is a shearing blade 4 consisting of a fixed blade 2 and a movable blade 3 that slides back and forth in contact with the upper surface of the fixed blade 2.
is provided.

A linear slide frame 5 that also serves as a decorative frame is formed on both sides of the front part of the hair clipper body 1, and a plurality of concave stopper receivers 6 for adjusting the hair cutting height are formed on this slide frame 5. It is said to be a joint.

Next, an attachment 8 having comb teeth 7 formed at its tip and having a semicircular cross-sectional shape on the lower surface of the hair clipper body 1 is provided.

On both side edges of this attachment 8, inclined portions 9 which are inclined outward from the inner circumferential surface in the expansion direction are formed over the entire length, and on both side edges slightly below these inclined portions 9 are the slides. A linear slide groove 10 into which the frame 5 is fitted is formed.

A convex stopper 11 is formed in this slide groove 10 and serves as an engaging portion to be engaged with the stopper receiver 6 .

Furthermore, a slide rib 13 is formed protruding from the bottom of the inner circumferential surface of the attachment 8 and is fitted into a slide groove 12 formed on the lower surface of the clipper main body 1 in the front-rear direction.

Further, a triangular guide rib 14 is formed on the inner circumferential surface of the attachment 8 to protrude outwardly from the slide rib 13 and serves as a deformation fulcrum.The apex of this guide rib is rounded by a small arc. The apex is joined to the outer peripheral surface of the clipper main body.

Moreover, the center part of the bottom surface of the attachment 8 is a pressing part 8.
It is said to be a.

Furthermore, the guide rib 14 and the slide rib 13
A plate spring locking groove 15 is formed along the circumferential direction on the inner circumferential surface of the attachment 8 adjacent to the plate spring locking groove 15 , and both ends of the plate spring locking groove 15 reach a position close to the stopper 11 . Leaf spring locking holes 16 and 17 are formed in the portion to pass through the attachment 8, and the upper edges of these leaf spring locking holes 16 and 17 are provided with uneven leaf spring locking portions with recessed outer peripheral surfaces. 18 and 19 are formed.

The leaf spring locking groove 15 has pressing portions 20 and 21 bent in an L shape at both ends to engage with the leaf spring locking portions 18 and 19.
A leaf spring 22, which is curved with a radius of curvature smaller than the radius of curvature of the inner circumferential surface of the attachment 8, is attached while being expanded and biases both side edges of the attachment 8 toward each other.

In addition, a hair escape hole 23 is provided in the bottom of the attachment 8.
is opened, and the bottom surface of the outer circumferential surface of the attachment 8, which is the back side of the mounting position of the leaf spring 22, has a plurality of protrusions formed to protrude at a slight height in the left-right direction. A non-slip portion 24 is formed.

In such a configuration, when attaching the attachment 8 to the clipper body 1, the attachment 8 is positioned on the lower surface of the clipper body 1 and pushed up.

As a result, the slide frame 5 fits into the slide groove 10,
Furthermore, since the inclined portions 9 are formed on both side edges of the attachment 8, this fitting is performed extremely easily.

Furthermore, the slide rib 13 fits into the slide groove 12,
The apex of the guide rib 14 joins to the outer peripheral surface of the clipper body, and attachment of the attachment 8 to the clipper body 1 is completed.

When the attachment 8 is pushed up, the attachment 8 expands outward, but after the slide frame 5 fits into the slide groove 10, the diameter of the attachment 8 contracts inward due to its own elasticity, especially the elasticity of the leaf spring 22. , the fitting is reliable.

Through this fitting, the stopper 11 engages with the stopper receiver 6, so that movement of the attachment 8 in the front-rear direction is fixed.

Further, by fitting the slide frame 5 into the slide groove 10 and fitting the slide 13 into the slide groove 12, movement of the attachment 8 in the circumferential direction is fixed.

Furthermore, since the apex of the guide rib 14 is joined to the outer circumferential surface of the hair clipper body 1, movement of the attachment 8 in the front-rear direction and circumferential direction is even more reliably prevented, so that the fixed state of the attachment 8 is extremely stable.

By fixing the attachment 8 to the clipper body 1, the distance between the comb teeth 7 and the shearing blades 4 is determined, and the hair cutting height is determined.When attaching the attachment 8 to the clipper body 1, the stopper 11 can be Stopper receiver 6
By adjusting the position to engage with the attachment 8, it is possible to set the hair cutting height to a desired height at the same time as attaching the attachment 8.

However, since it is quite difficult to align the position in this way, the attachment 8 is attached to the clipper body 1.
It is better to change the hair cutting height after installing it.

In this case, the anti-slip portion 24 is pressed against the clipper main body 1 side.

This pressing operation causes the slide rib 13 to move into the slide groove 1.
The guide rib 14 is pressed against the bottom of the clipper body 1.
slides outward while bonding to the outer peripheral surface of the

Moreover, since the apex of the guide rib 14 is rounded, it slides extremely smoothly, and even if the joint part of the guide rib 14 moves after sliding, the state of joint with the outer peripheral surface of the clipper body 1 remains the same as before sliding. be done.

As the guide rib 14 slides, both side edges of the attachment 8 expand outward, and the stopper 11 and the stopper receiver 6 are disengaged from each other, and the slide groove 10 and the slide frame 5 are disengaged from each other.

When the stopper 11 and the stopper receiver 6 are disengaged, the attachment 8 becomes movable in the front-back direction, and from this state, the non-slip part 24 is pressed against the clipper body 1 side and biased in either the front-back direction. Then, the attachment 8 slides in the urging direction, the distance between the comb teeth 7 and the shearing blade 4 changes, and the hair cutting height is adjusted.

Then, when the stopper 11 is positioned facing any stopper receiver 6 and the finger is released from the anti-slip part 24, the attachment 8 uses its own elasticity, especially the elasticity of the leaf spring 22, to move the top of the guide rib 14 to the clipper body. The slide frame 5 fits into the slide groove 10 and the stopper 11 engages with the stopper receiver 6 to set the new hair cutting height. Ru.

Note that when the attachment 8 is slid in the front-rear direction, the slide rib 13 fits into the slide groove 12, so that the attachment 8 is prevented from moving in the circumferential direction.

In addition, by forming the anti-slip portion 24, the thickness of the attachment 8 in the area where the anti-slip portion 24 is formed is made thinner, increasing the elasticity of the attachment 8 and reinforcing the attachment 8. It prevents your fingers from slipping when applying pressure.

Note that after the slide groove 10 and the slide frame 5 are fitted together and the stopper 11 and the stopper receiver 6 are disengaged, the clipper main body 1 must be slightly rotated in the direction in which the slide frame 5 intersects the slide groove 10. For example, even if the finger is removed from the anti-slip portion 24, the slide frame 5 does not fit into the slide groove 10, and the attachment 8 can be easily removed from the clipper body 1.

When attaching the leaf spring 22 to the attachment 8, as shown in FIG. If the leaf spring 22 is aligned with the inner peripheral surface of the attachment 8 and the other pressing part 21 is slid toward the other leaf spring locking hole 17, the pressing part 2
1 easily engages with the leaf spring locking portion 19, and the pressing portion 20 also engages with the leaf spring locking portion 18.

Therefore, the leaf spring 22 can be easily attached without screwing or welding, and the number of parts and manufacturing steps can be reduced.

Furthermore, the pressing parts 20 and 21 are arranged at different levels in the leaf spring locking part 18.
, 19 while urging both side edges of the attachment 8 in a direction closer to each other, the plate spring 22 is reliably prevented from wobbling or falling off.

A portion of the hair sheared by the shearing blades 4 passes through the lower surface of the clipper body 1 and is discharged from the escape hole 23, and the remaining hair naturally falls from the upper surface of the clipper body 1.

Therefore, sheared hair does not accumulate on the top side of the clipper body 1 and the top of the shearing blade 4, and subsequent hair is smoothly guided to the shearing blade 4, so that the cutting edge of the shearing blade 4 is always in a good state. It is maintained.

This idea is based on forming guide ribs on the inner peripheral surface of the attachment as described above, so that when the attachment is attached to the clipper body, the apex of the guide rib joins to the outer peripheral surface of the clipper body, thereby stabilizing the attached state of the attachment. When the pressing part of the attachment is pressed toward the clipper body, the apex of the guide rib joins the outer circumferential surface of the clipper body and slides in both directions of the clipper body, becoming a deformation fulcrum, and both edges of the attachment move in the expansion direction. This spreads out and disengages the engaging part, making it easy to remove the attachment or slide it to any fixed position.Furthermore, when the pressing force on the bottom of the attachment is released, the guide ribs can be removed from the clipper body. This has the advantage of being able to return toward the bottom side of the clipper body while being joined to the outer peripheral surface of the clipper body, and allowing the engaging portion to be engaged at any fixed position.
