US Pat.

The foregoing and other objects of the present invention are achieved by providing a hair braiding device having a support member or handle adapted for hand gripping, the handle being pivotable with respect to the handle. The bird has members. The bird member has an arcuate rack portion for engaging a gear member connected to the shirt Y, with which the bird rotates when the member is energized. The shaft is connected to the disc housing through a ratchet mechanism.
The housing is shaped like a pillow to provide manual restraint during actuation. The disc housing has a pair of rotating clamps spaced apart from each other supporting a member, the outer end of which is used for clamping hair strands;
Another type of pincer has a member end connected to a gear mechanism within the housing. The hair strand is pinched (=1) The member is rotated repeatedly against the biased gravity of the spring, the housing is held down by hand, and the members are simultaneously rotated in the same direction to hold the hair. Twist the bundle. The gear mechanism in the housing includes a pair of pawls cooperating with an L drive gear, the gears being connected to each other to prevent the bird from pinching during reverse movement of the member. prevents the member from rotating in the opposite direction. After the desired twist is achieved, the housing is released and the member is repeatedly moved downwards, causing the bird to move the housing in one direction as the member is pushed down. As the housing is locked to the handle, the gear, teeth and eye together with the gear carried on the housing work together to allow the bird to rotate in reverse direction of the housing during reverse movement of the member. This prevents rotation and leaves the housing unrestricted.I)
Therefore, the hair is forced to be trapped in one direction, creating an i-clog.

Other objects, features and advantages of the invention will become apparent from a reading of the drawings and the specification. In the figures, the same reference numerals indicate the same elements.

Now, let's talk about the drawings. In particular, the first and second
In the figure, a human or doll head 10 is shown in which first and second hair tresses] 2.14 are connected to the first and second hair tresses of a braiding device, generally designated 20. The receiver is placed in the clamping member 16.18.

The knitting device 20 is arranged to be hand-held and hand-operated, and includes a support structure or handle 22 that is biased into retention with one hand of the knitting operator. The biasing member or bird positioned as shown in FIG.
4 can be rotated freely. During operation, the trigger member 24 is repeatedly moved up and down against the force of the spring 26 against the handle 22 and trigger member 24, as will be explained hereinafter. The portions of the Y rigger member 24 with separate pivot points are shaped to form an arcuate toothed rod 28 that cooperates with a gear member and is coupled through a one-way clutch or ratchet mechanism. 7) to selectively rotate the disc housing 32 and ultimately cause the rake to move the members 16, 18 as desired.

In 11j, the hair braiding device 20 is explained in detail.
The operation will be explained with reference to FIGS. 1 and 2. (
Parts 1G and 18 (in the form of crocodile clips) have generally parallel shaft protrusions 36, 38 which are connected to the gear members of the gear mechanism within housing 32. The clamping therefore allows the members 16, 18 to rotate with respect to each other and with respect to the housing.

The housing rotates with respect to the handle 22 and the pincers swap positions of the members 16,18. Referring to FIG.
G, 18 are clamped into their respective clip portions. The operator then grasps the housing 32 with one hand 40 to prevent the housing 32 from rotating. Meanwhile,
With the other hand (not shown), the operator grasps and twists the handle 22 and trigger member 24 to pivot the trigger member toward the handle 22 against the force of the spring 26. At the same time, the clamping member 16.18 (shaft 36
．． 38 in the same direction (as indicated by the arrows surrounding each). Since the disk housing is stationary, the clamping members rotate with respect to the housing 32. This rotation imparts a twist to the hair tresses 12, 14 respectively.

When the member 24 is released and the bird returns under the force of the spring 26 (and the housing 32 is stopped), the ratchet a mechanism 30 is disengaged and the bird 24 is released.
is made to move in the opposite direction. The trigger member 24 is then twisted until the hair tress 12.14 is twisted as desired.
It gets tightened again.

Referring to FIG. 2, after the desired stiffness is achieved, the housing 32 is released and is free to rotate relative to the handle P. When the F trigger member 24 is pivoted relative to the handle 22, the housing 32 rotates in a direction opposite to the twisting direction (as indicated by the arrows surrounding the member), and the gripper is rotated relative to the handle 22. Member 16
．． Swap the position of 18. As shown in Figure 2,
Depressing the trigger member 24 in the direction of the arrow adjacent the trigger member causes the housing 32 to rotate clockwise (also seen in FIG. 4). As will be explained hereinafter, when the force of spring 26 releases member 191 to its normal position, housing 32
remains stationary without assistance and twists the hair 12
and 14 are knitted in one direction. This means that this effect is achieved by incorporating a pawl and a spring into the gear mechanism inside the housing, and the device 20
During operation, the hair tresses 12, 14 are kept intact.

The overall structure of the hair braiding device 2° will be explained with reference to FIGS. 3 to 6. Handle 22 is generally hollow and includes an integrally formed protruding portion 42 surrounded by fill-like portion 25 of spring member 26 . The spring member 26 has one free end that is restrained by the inner wall of the handle 22 and another free end that is pressed against the shoulder portion of the member 24. Handle 2
The opposite end of handle 22 is shaped to receive a shaft 44 which is locked at one end in an opening 46 of a projection 48 formed in handle 22. A gear member 5o is fixed to the other end of the shaft 44.

Midway between the ends of the shirt 44 (from left to right as shown in FIG. 3) is a compression spring 52 that surrounds the shirt 44. The unitary member is mounted for rotation with respect to the shaft 7) 44.

The unitary member 56 has a drive gear portion 56a and a Kuchiev 1 portion 56b. The second single member 5B is the shaft 7)
44, said second unitary member has a Kuchiev 1 part S8a and a gear part 58b, which parts have a shaft 7) gear 50 at one end and a stop at the opposite end. 60 is held on the shaft between its ends.

Within the housing 32, the shaft protrusion 36.38 of the scissor member is secured to first and second gear members 66.68. The gear members 66,68 engage the main drive gear portion of the second unitary member 58 (see also FIG. 4). The gear members 66,68 have shaft protrusions 36,38, each protrusion extending through the gear members 66,68, and bearings to the housing 32 provide a supporting connection.

Functionally, compression spring 52 forces ratchet portions 56b and 58a into cooperative relationship during rotation of drive gear portion 56a due to simultaneous movement of the drive gear portion (in which housing 32 is held). During the counter-rotation of 56a, the respective cutief 1 portions are caused to separate. As will become clear later, both the first and second vehicle parts 5
6.58 is rotatably installed on the shaft 7) 44, and only the shaft 7) gear 50 is fixed to the shaft 44. As seen in FIG. 4, the interior of housing 32 is cup-shaped with a generally circular cross section.

First and second leaf springs are disposed radially within the housing 32, the leaf springs 70,72 having first ends secured to the inner wall of the housing 32 and having first and second teeth. Extending inwardly for adjacent engagement with retaining members 74,76. Each pawl 74 and 76 is generally identical in configuration and is pivotally mounted between the top and bottom walls of the housing 32. The pawl 74 is pivoted and urged into engagement with the shaft gear 50 by the leaf spring 70, while the pawl 76 is pivoted and pressed into engagement with the shaft gear 50 by the leaf spring 72. Pushed into engagement with drive gear portion S8b.

As seen in FIG. 4, the /'% housing 32 is not restrained, and when the drive gear 58b rotates in the clockwise direction indicated by the arrow, the housing 32 (as indicated by the arrow) ) similarly rotates clockwise. shaft 4
4 and shaft gear 50 are fixed relative to the nozzle 22 during this clockwise rotation of the housing 32, so that the pawl 74 does not engage the teeth of the gear. When the rear member 24 is released and the housing 32 is no longer restrained, counterclockwise rotation of the housing is restrained by the cooperative action of the tooth stop 74 and the shutter 7F/gear 50. The pawl and shaft gear 50 are fixed relative to the handle 22 and not to the housing 32. When the housing 32 is restrained and the drive gear S8b rotates clockwise, the pinching gear 66
．． 68 simultaneously rotates clockwise (as indicated by the arrow). This condition occurs when a "twisting operation" is performed.

This work and its reason will be explained later when we explain the use of the device.
Two things become clear.

The relative axial positions of the pawls 74, 76 are shown in FIGS. 3 and 5, where the pawls 74 and 76 are aligned with the shaft gear 50 and drive gear portion 58b, respectively. It is positioned as As shown in FIGS. 3 and 5, toothed rod 28 cooperates with drive gear portion 56a of first floret member 56. As shown in FIGS.

To illustrate the intended use and operation of the device 20, the method of operation (as previously described with respect to FIG.
We will first discuss "twisting" 4 and then we will discuss braiding the twisted hair tresses (as described above with respect to FIG. 2).

To explain with reference to FIGS. 1 and 3, hair bundle 12.14
The pincer is secured within member 16.18, and when housing 32 is immobilized by hand (as shown in FIG. 1), trigger member 24 is rotated against the force of spring 26. It will be done. While the bird is moving member 24, tooth rack 28 drives first unitary member 56 clockwise (as shown in FIG. 4). Rotation of this unitary member 56 is transmitted through the ratchet mechanism 30 (comprising portions S6b and S8a) to a second unitary member 58, as shown in FIG. rotate clockwise. During this rotation, the tooth stop 76 engages with the teeth of the drive gear portion 58b, and the tooth stop 74 engages with the teeth of the shear 7) gear 50. Both gears 66, 68 rotate counterclockwise at the same time, twisting the hair tress 12, 14 (as shown in Figure 1). When the bird releases member 24 and housing 32 is restrained, drive gear portion 58b attempts to rotate clockwise, but this movement is inhibited by pawl 76 which detents within its gear teeth. , thus keeping the gear part 58b stationary together with the gears 66,68.

When the bird member is then pivoted, this movement causes the hair strands 12.
Steps 14 are repeated until the desired amount is reached. During reverse movement of member 24, portion S6b of ratchet mechanism 30 is displaced about the axis against the force of compression spring 52 and moves tooth rack 28 without corresponding movement of drive gear portion 58b. make it happen.

Once the desired twist in each tress 12,14 has been achieved, the braiding operation begins. During this operation, the housing 32 is released and the trigger member is repeatedly moved up and down to remove the hair strands 12.
Perform 14 braids. As shown in FIG. 4, when the housing 32 is released and the bird is compressed, the drive gear portion S8b rotates clockwise so that the housing 32 rotates clockwise (as indicated by the arrow). Let it rotate. When the shirt F gear 5o is fixed in place, the tooth catch 74 is independent of the teeth of the shaft gear 5o, and the position of the gears 66, 68 with the hair strands is swapped.

When the trigger member 24 is released, the drive gear portion S8b tries to rotate counterclockwise, but since the pawl 76 is engaged with the gear portion 58b, reverse rotation is suppressed.

Accordingly, the shaft gear 50 is fixed in place;
The housing is in place without back movement, and the ratchet mechanism 30 then causes the trigger member 24 to move back. Similarly, during this reverse movement, the gear portion '58
Gear members 66 and 68 are also stationary, since neither b nor the shaft gear is moving. As a result, ) 1 member 2
By repeatedly moving 4 up and down, the housing is released and becomes unrestrained, allowing braiding of the hair tresses 12 and 14 to take place. (See FIG. 2) With this movement, the hair tresses 12, 14 are each twisted in the first direction, and the weaving of the thus twisted hair tresses is performed by rotation in the opposite direction. This movement in the opposite direction helps to hold the braid in place and the braiding device is removed after the braiding is complete. Furthermore, this opposing movement serves to hold the parts of the mechanism in place without unduly deteriorating the mechanism from an operational standpoint.

While the preferred embodiment has been shown and described, it will be understood that various modifications may be made within the scope of the invention.
