Description

The present invention relates to a hairdressing and beauty salon, and more particularly to a hairdressing and beauty salon characterized by a joining structure of a blade member and a finger ring member of a blade body constituting the hairdressing and beauty salon.

The hairdressing salon is made by pivoting two blades. As shown in FIG. 25, the blade body is made of a semi-finished blade member and a finger ring member made of a material such as metal or ceramic having functional characteristics required for each member, such as forging or casting. After being manufactured separately by means, both are joined and the surface is polished or bladed to complete the finished product.

As a means for joining the blade member and the finger ring member, there are means such as tacking and screwing in addition to welding. However, those that are fastened or screwed are inferior in welding stability, accuracy, strength, and design compared to welding, and are generally performed by welding (for example, Patent Document 1 to Patent Document 3). reference). In addition, there are various types of barbers and beauty salons, such as cut scissors with straight blades, and scissors with one blade shaped like a comb. There are various shapes of blades and finger rings.

Therefore, in order to provide barbers and beauty salons that meet the various needs of barbers, barbershops have prepared various shapes of blade members and finger ring members in semi-finished products in advance. After the order is received, the blade member and the finger ring member according to the order are selected and welded, and then various processes such as grinding and blade attachment are performed to finish and deliver the finished product. However, it takes time from the customer's order to delivery because it takes time to perform precision adjustment by welding, grinding, finishing and welding deformation until the finished product is finished.

On the other hand, there is a demand for a hairdresser who uses a barber / beauty salon to always use a barber / beauty salon that is familiar and familiar to the hand. Nevertheless, for example, when requesting a manufacturer for sharpening processing when the sharpness of a barber / beauty salon has fallen, the blade member and the finger ring member are not treated even if only the blade member is processed. Since they were joined by welding, they could not be separated, and it was necessary to leave the hairdressing salon directly to the manufacturer. For this reason, barbers need to prepare spare barbers, and during that time they were forced to use barbers not familiar with their hands.

Some hairdressers seek a hairdressing salon with enhanced uniqueness by putting a pattern on the finger ring or blade of the hairdressing salon or attaching jewelry. However, if the blade member and the finger ring member cannot be separated, for example, if the sharpness does not recover even after sharpening, and the repair is not possible, the entire barber must be replaced with a new one. No. In this case, even if the barber / beauty salon was decorated, it had to be processed again when it was replaced with a new barber / beauty salon. .

This figure is the figure which saw the finger ring member 210, the blade member 220, and the connection member 230 from the AA cross section of FIG. In order to join the finger ring member 210 and the blade member 220, first, as shown in FIG. 23A, the protrusion 213 formed on the finger ring member 210 is inserted into the fitting portion 224 formed on the blade member 220. Next, as shown in FIG. 23 (b), the locking claw portion 231 at one end of the connecting member 230 is locked to the locking groove portion 214 of the finger ring member 210, and the fitting convex portion 232 at the other end is set to the blade member 220. After the fitting recess 225 is fitted, the screw 240 is tightened. At this time, the second vertical taper portion 233 formed in the fitting convex portion 232 contacts the first vertical taper portion 226 formed in the fitting concave portion 225.
Then, as shown in FIG. 23C, when the screw 240 is tightened and the fitting convex portion 232 is further submerged in the fitting concave portion 225, the fitting concave portion 225 and the fitting convex portion 232 are vertically moved. In the direction in which the second longitudinal taper portion 233 is in sliding contact with the first longitudinal taper portion 226 and is attracted to each other between the finger ring member 210 and the blade member 220 at the same time as being pressed in (arrow C direction). A force that moves in a certain vertical direction (arrow D direction) works, and the joining end surfaces of the finger ring member 210 and the blade member 220 are brought into close contact with each other.
That is, as the pressure contact between the fitting concave portion 225 and the fitting convex portion 232 increases, the adhesion between the joint end surface on the finger ring member 210 side and the joint end surface on the blade member 220 side proceeds.
Here, even when the fitting concave portion 225 and the fitting convex portion 132 are in a completely press-contacted state, the fitting concave portion 225 and the fitting convex portion 232 are arranged so that the fitting convex portion 232 does not bottom out. The depth of the fitting recess 225 is formed deeper than the thickness of the fitting projection 232 so as to ensure a clearance therebetween. For this reason, the fitting convex portion 232 sinks into the fitting concave portion 225 due to the pressure contact between the fitting convex portion 232 and the fitting concave portion 225, and a step is generated between the finger ring member and the blade member and the connecting member. Is also possible. However, even if such a step occurs, the step is extremely small and does not affect the design of the blade.

Next, the effect | action of the 1st width direction taper part 227 formed in the fitting recessed part 225 and the 2nd width direction taper part 234 formed in the fitting convex part 232 is explained in full detail. FIG. 24 shows a view of the finger ring member 210, the blade member 220, and the connecting member 230 as seen from the BB cross section shown in FIG.
As shown in FIG. 24, the fitting convex portion 232 of the connecting member 230 is simply fitted into the fitting concave portion 225, and a screw (not shown) is tightened to press the fitting concave portion 225 and the fitting convex portion 232 together. And the 1st width direction taper part 227 and the 2nd width direction taper part 234 are slidably contacted. Then, a force to move the fitting convex portion 232 from both sides in the width direction (arrow E direction) toward the center of the fitting concave portion 225 acts, and the fitting convex portion 232 is positioned at the center of the fitting concave portion 225. In addition, the direction is determined so that the fitting concave portion 225 and the fitting convex portion 232 are parallel to each other.
When the sliding movement between the first width direction taper portion 227 and the second width direction taper portion 234 is completed, that is, when the force applied to the fitting convex portion 232 from both sides in the width direction is balanced, the fitting is performed. The convex portion 232 is fixed at a predetermined position in the width direction in the fitting concave portion 225, and at the same time, the direction is determined so that the fitting convex portion 232 is arranged straight with respect to the fitting concave portion 225.

The finger ring member 210 and the blade member 220 can be easily separated by loosening and removing the screw 140 that fixes the connecting member 230.

The present invention has been described above based on the first and second embodiments. However, each embodiment can be variously improved and modified without departing from the spirit of the present invention, and the technical scope of the present invention. Includes these improved variants.

For example, in Example 1, the joint convex portion formed on the blade member is formed in a substantially wedge shape with the thickness gradually decreasing from the root to the tip, but is not limited to this, for example, Further, a slit may be formed on the joint convex portion to give flexibility, or a rib may be formed so that the joint convex portion can be brought into close contact with the finger ring member.

Moreover, in Example 2, the 1st vertical direction taper part of the fitting recessed part formed in a blade member, the 1st width direction taper part, and the 2nd vertical direction taper part of the fitting convex part formed in a connection member, The second width direction tapered portions are continuously provided so as to be orthogonal to each other, but may be continuously provided in a curved manner. Moreover, although the end surface of the handle | steering-ring part of a finger ring member and the end surface of the pivoting part of a blade member are each formed in circular arc shape, you may form this in linear form. Furthermore, the first width direction taper portion of the fitting recess and the second width direction taper portion of the fitting tongue piece are formed on both sides of the first vertical taper portion and the second vertical taper portion, respectively. Alternatively, it may be formed only on one side of the first longitudinal taper portion and the second longitudinal taper portion.

In addition, in Example 1 and Example 2, the connection member is attached by screw tightening so that the finger ring member and the blade member can be joined and separated freely, but when the separation function is not required. Instead of screw tightening, for example, fixing means that cannot be removed such as caulking or riveting may be employed. In this case, in order to further increase the joint strength, spot welding or partial welding may be performed together. When such a non-removable fixing means is used, it is naturally impossible to separate the blade member and the finger ring member after joining them once. It is advantageous in that it can be joined more easily than welding.
