Description

  The present invention relates to a bag and a bag set suitably used in, for example, a barber shop or a beauty salon.

  2. Description of the Related Art Conventional hairdressing scissors are widely used in a structure in which flat portions formed on a base portion of a blade body are in contact with each other and are pivotally attached to a pivot. However, if the flat parts of the double-edged blades are in contact with each other, the opening / closing operation becomes heavy and fatigue increases, which is not suitable for long-time hairdressing work. There has been a problem that a twisting phenomenon occurs and the hair cannot be cut smoothly and under uniform conditions.

  For this reason, the present applicant has developed a barber for hairdressing having a structure described in Patent Document 1. In this structure, a through hole is provided in the flat portion formed at the base of the upper blade body, and the lower half of the short cylinder body is slidably fitted into the through hole, and the short cylinder body A pivot is inserted through a bearing at the center, and the lower half of the pivot is pivotally attached to the flat portion of the lower blade opposed to the flat portion of the upper blade with a small gap. The large-diameter head of the pivot is locked to the upper end surface of the short cylinder. Further, a screw shaft projects from the upper blade body in the vicinity of the rear side of the short cylindrical body, and a nut that is screwed to the screw shaft and the short cylindrical body are twisted and connected by a restricting piece, and further, the front end of the short cylindrical body Is provided with a fulcrum that is in contact with and supported by the flat portion of the upper blade.

  However, the structure described in Patent Document 1 has problems such as a problem that the nut is naturally rotated and loosened, and that it is difficult to finely adjust the meshing pressure between the two blades. In view of such problems, the present applicant has made it possible to easily and accurately perform fine adjustment of the meshing pressure of the two blade bodies according to the user as well as prevention of twisting of the two blade bodies as disclosed in Patent Document 2. The structure of the pivot part in the hairdressing heel was developed.

JP 09-038348 Japanese Patent Laid-Open No. 2001-259260

  According to the structure described in Patent Document 2, although the above-described advantages can be obtained, there is a large individual difference in how to use the heel (how to apply force, etc.). There is a possibility that the force with which the blades are engaged and slidably contact cannot be sufficiently suppressed. In this case, an excessive force is applied to both blades, causing the blade to be damaged. Here, the use of the scissors means to open / close the scissors by applying a force in a biased direction so as to increase the meshing force between the blades.

  In addition, when using the hairdressing scissors, the pressure of hand-handling reaches 1 to 1.5 kg. At this time, the meshing pressure between the upper and lower blade portions at the cutting edge portion that is close to the important point intersects with each other due to the resistance of the pivoting portion, but it is considered that it reaches 7 to 10 kg from the simple calculation of the insulator. Experience has shown that blades that are actually sharply polished by use are deformed and become burrs and warp on the opposite side. For this reason, it has become a big problem how to suppress the hand-pumping force during the operation.

  Also, for example, when two ball bearings are loaded into the holder part of the pivoting part at intervals of 5 mm, the blade calculation starts from 21 kg (= distance 70 mm / 5 mm × 1.5 kg from the center to the point of action of the finger ring) The pressure obtained by subtracting the force transmitted to the part is applied to the periphery of the ball bearing. The magnitude of this pressure greatly exceeds the pressure limit of the small ball bearing, and the ball bearing is easily damaged. Further, it is strongly desired to reduce the size of the barber for hairdressing from the viewpoint of ease of use and the like in addition to improvement in pressure resistance. Therefore, in the field of hairdressing scissors, a design that takes into account the pressure resistance that influences the structure in a situation confined to a small space is particularly important.

  In view of the above-described problems, the present invention should enable a smooth opening and closing operation over a long period of time, improve the pressure resistance by simplifying the structure, and easily and accurately adjust the meshing pressure between the blades. The purpose is to provide a bag that can be made. Moreover, an object of this invention is to provide a scissors set provided with such a scissors and the tool for performing the adjustment.

A flanged cylindrical body in which a lower part is fitted to a through hole penetrating the body up and down, a lower part is fixed to the lower blade body, and an upper part is rotatably attached to the flanged cylindrical body A shaft, a fulcrum that forms a gap starting from itself in the longitudinal direction of the upper blade between the upper blade and the flange, and the flanged cylinder using the fulcrum And an adjustment section that makes it possible to adjust the inclination angle in the longitudinal direction with respect to the upper blade body.

  According to this configuration, since the lower blade body is integrated with the flanged cylinder through the shaft body, it is possible to change the inclination angle of the lower blade body with respect to the upper blade body using the adjustment unit. It is. In other words, with this type of scissors, it is possible to finely adjust the meshing pressure of the pair of blades corresponding to the user's scissors, and to prevent the blades from being deformed by the pressure of the hand-handling. it can. In addition, since the fulcrum is used for changing the tilt angle, fine adjustment of the meshing pressure can be performed easily and accurately, and the pressure resistance can be improved with a simple structure of the rod. It is.

  In the scissors having the above-described configuration, the adjustment portion is inserted into an insertion hole penetrating the collar portion up and down and is screwed into a second screw hole provided in the upper blade body and extending vertically. It is preferable to have a screw. According to this structure, since the adjustment part is comprised with the screw, it is easy to make a collar into a simple structure.

  In the scissors having the above-described configuration, a pair of the fulcrum portions may be arranged so as to sandwich the shaft body in the lateral direction of the upper blade body.

According to this configuration, it is easy to finely adjust the meshing pressure by the adjusting unit.

  In the bag having the above-described configuration, it is preferable that the pivot portion has a bearing into which the shaft body is inserted while being inserted into the flanged cylinder. According to this configuration, it is easy to smoothly perform the relative rotation between the upper blade body and the lower blade body.

  In the scissors having the above configuration, the pair of fulcrum portions may be integrally provided on the lower surface of the scissors.

  In the scissors having the above-described configuration, the lower portion of the shaft body is screwed to a first screw hole provided on the lower blade body and extending vertically, and the first screw hole moves the lower blade body up and down. A thin screw body that contacts the lower surface of the shaft body may be screwed into the first screw hole. In this configuration, since the vertical position of the shaft body can be adjusted by the double screw, fine adjustment of the small interval between the flat portions of the pair of blade bodies can be stably performed.

  In the bag having the above configuration, an adjustment hole for inserting the first adjustment tool is formed in the lower surface portion of the shaft body, and an opening for exposing the adjustment hole is formed in the thin screw body, A configuration may be employed in which the shaft body can be screwed and unscrewed using the first adjusting tool inserted into the adjusting hole. This configuration is convenient because it is not necessary to remove the thin screw body in order to adjust the vertical position of the shaft body.

  In the scissors having the above-described configuration, an engagement portion that engages with the second adjustment tool is formed on the thin screw body, and the thin screw is used by using the second adjustment tool that is engaged with the engagement portion.

FIG. 2 is an enlarged schematic plan view showing a part of the bag S according to the embodiment of the present invention. FIG. 2 shows a state in which the heel S is opened. As shown in FIGS. 1 and 2, the scissors S include a pair of long and narrow blade bodies 1 and 2. Each blade body 1, 2 has flat portions 1 a, 2 a formed in a flat plate shape at a substantially central portion in the longitudinal direction. Ring-shaped portions 1b and 2b are provided at one end in the longitudinal direction of each blade body 1 and 2, respectively. The first ring-shaped portion 1b is a so-called finger ring. The second ring-shaped portion 2b is a so-called thumb ring. In addition, each blade body 1, 2 has a sharp blade formed from the flat portions 1a, 2a to the end portion on the other side in the longitudinal direction (hereinafter referred to as the tip portion of the blade bodies 1, 2).

The saddle S includes a pivot portion 3 that pivots the pair of flat portions 1a and 1b vertically with a small interval.

  FIG. 3 is a schematic perspective view showing an enlarged view of the pivoting portion 3 provided in the bag S according to the embodiment of the present invention and the periphery thereof. FIG. 4 is an exploded perspective view of the pivot portion 3 included in the heel S according to the embodiment of the present invention. FIG. 5 is a schematic cross-sectional view of the pivot portion cut at the position AA in FIG. 2. FIG. 6 is a schematic cross-sectional view of the pivot portion cut at the BB position in FIG. 2. With reference to FIGS. 3-6, the structure of the pivot part 3 with which the collar S is provided is demonstrated in detail.

  The pivot part 3 has a flanged short cylinder 31. The flanged short cylinder 31 is an example of the flanged cylinder of the present invention. The flanged short cylinder 31 has a configuration in which a plate-like flange 31a is provided on the outer periphery of an annular cylinder extending in the vertical direction. Specifically, the collar portion 31a is provided slightly below the central portion in the vertical direction of the cylindrical body. The collar portion 31a has an oval shape in which the longitudinal direction of the upper blade body 1 (the left-right direction in FIG. 5 and the direction perpendicular to the paper surface in FIG. 6) is the major axis direction when viewed from above. The shape of the collar part 31a is not limited to this, For example, a rectangular shape, a circular shape, etc. may be sufficient in top view.

  A pair of protrusions 31b are formed on the lower surface of the flange 31a. The pair of protrusions 31b are spaced from each other in the short direction of the upper blade body 1 (the direction perpendicular to the paper surface in FIG. 5, the left-right direction in FIG. 6). The pair of protrusions 31b are arranged so as to sandwich a shaft body 32 described later. In the present embodiment, each protrusion 31b has a substantially circular shape when viewed from below. The shape of each projection 31b is not limited to this, and may be, for example, a rectangular shape extending in the short direction when viewed from the bottom. The tip (lower end) of each protrusion 31b is preferably rounded. The pair of protrusions 31b are preferably the same shape. In addition, a pair of projection part 31b is an example of a pair of fulcrum part of this invention. The pair of protrusions 31b plays a role of forming a gap starting from itself in the longitudinal direction of the upper blade body 1 between the upper blade body 1 and the flange portion 31a. As a result, a seesaw-like structure with the pair of protrusions 31 b as fulcrums is obtained, and the flange 31 a can be inclined with respect to the upper blade body 1.

  A pair of insertion holes 31c are formed in the flange portion 31a so as to be spaced apart in the longitudinal direction of the upper blade body 1. The pair of insertion holes 31 c are arranged so as to sandwich the cylindrical portion of the flanged short cylindrical body 31. Further, the pair of insertion holes 31c are arranged so as to sandwich a shaft body 32 described later. Each insertion hole 31c is provided in a substantially circular shape when viewed from above. Specifically, each insertion hole 31c has a shape in which a large-diameter through hole and a small-diameter through hole overlap each other. In other words, each insertion hole 31c has a step structure in which the upper side is wide and the lower side is narrow. As will be described in detail later, this structure makes it possible to reduce the protruding amount of the adjusting screw 36 on the upper surface of the flange portion 31a. The shape of each insertion hole 31c is not limited to this, The shape may be changed suitably.

  A through hole 1c penetrating in the vertical direction is formed in the flat portion 1a of the upper blade body 1. The through hole 1c is substantially circular when viewed from above. As for the short cylinder 31 with a collar, the cylinder part below the collar part 31a is fitted by the through-hole 1c. In a state where the flanged short cylinder 31 is fitted in the through hole 1 c, the pair of protrusions 31 b abut on the upper surface of the flat portion 1 a of the upper blade 1.

  The pivot part 3 has a shaft body 32. The shaft body 32 has a large-diameter screw portion 32a at the lower end of a cylindrical shaft portion extending in the vertical direction. A first hexagonal hole 32b extending upward is formed at the center of the lower end of the substantially cylindrical large-diameter screw portion 32a. The first hexagonal hole 32b is an example of the adjustment hole of the present invention. The flat portion 2a of the lower blade body 2 is formed with a first screw hole 2c extending in the vertical direction. The 1st screw hole 2c penetrates the flat part 2a of the lower blade 2 in this embodiment. The first screw hole 2c is substantially circular in top view. The shaft body 32 is fixed to the lower blade body 2 by screwing the large-diameter screw portion 32a into the first screw hole 2c. In other words, the lower part of the shaft body 32 is screwed to the lower blade body 2.

  The shaft body 32 has a shaft portion (upper portion of the shaft body 32) on the upper side of the large-diameter screw portion 32 a and is rotatably attached to the flanged short cylinder body 31. The pivot part 3 has a bearing inserted into the flanged short cylinder 31. In the present embodiment, the bearing is a ball bearing as an example. Specifically, the upper ball bearing 33 is arranged on the upper side inside the flanged short cylinder 31. Further, a lower ball bearing 34 is disposed on the lower side inside the flanged short cylinder 32. The shaft body 32 is inserted into the two ball bearings 33 and 34. Specifically, the shaft body 32 is in a state of being inserted into a through hole formed at the center of the two ball bearings 33 and 34. Thus, the shaft body 32 is attached to the flanged short cylinder body 31 so as to be rotatable.

  A third screw hole 32 c extending downward is formed on the upper surface of the shaft portion of the shaft body 32. On the upper part of the upper bearing 33, an upper flange 33a is provided. A lower flange 34 a is provided at the lower portion of the lower bearing 34. The upper flange 33a abuts on the upper end of the flanged short cylinder 31. The lower flange 34 a abuts on the lower end of the flanged short cylinder 31. The tightening screw 35 that is screwed into the third screw hole 32c and fastened presses the inner side of the upper end of the upper ball bearing 33 by the head portion 35a. The lower end inside of the lower ball bearing 34 is pressed against the large-diameter screw portion 32a. Thereby, the flanged short cylinder 31, the shaft 32, and the two ball bearings 33, 34 are integrated.

  In this embodiment, the four members 31 to 34 (the flanged short cylindrical body 31, the shaft body 32, and the two ball bearings 33 and 34) are integrated using the fastening screw 35. This is only an example. For example, the four members 31 to 34 may be integrated using a nut instead of a screw. In this case, instead of providing a female screw on the shaft portion of the shaft body 32, the upper portion of the shaft body 32 may be protruded from the upper bearing 33, and a male screw may be provided on the outer periphery of the protruding portion. Alternatively, the four members 31 to 34 may be integrated by bonding and fixing the two ball bearings 33 and 34 to the flanged short cylinder 31 or the shaft body 32.

  Moreover, since the shaft body 32 should just be rotatably attached to the flanged short cylinder 31, the two ball bearings 33 and 34 may not be provided depending on the case. In this case, it is necessary to configure so that the shaft body 32 does not fall off from the flanged short cylinder body 31. Using the ball bearing facilitates smooth relative rotation between the upper blade body 1 and the lower blade body 2.

  The pivot part 3 has a pair of adjusting screws 36. A second hexagonal hole 36b extending downward is formed on the top surface of the head 36a of each adjustment screw 36. The pair of adjustment screws 36 are inserted into the pair of insertion holes 31c. A part of a portion of the pair of adjusting screws 36 protruding from the insertion hole 31c is screwed into a pair of second screw holes 1d provided in the upper blade body 1 and extending in the vertical direction. In the present embodiment, the pair of second screw holes 1 d penetrate the flat portion 1 a of the upper blade body 1. The pair of second screw holes 1d sandwich the through hole 1c in the longitudinal direction. In other words, the pair of second screw holes 1d are provided so as to sandwich the shaft body 32 inserted through the through hole 1d. Each adjustment screw 36 is screwed into the second screw hole 1d in a state where the head 36a is inserted into the large-diameter through hole portion of each insertion hole 31c. For this reason, each adjustment screw 36 can suppress the protruding amount from the upper surface of the flange portion 31a to be small. In addition, as another device for reducing the protruding amount of the adjusting screw 36 on the upper surface of the flange portion 31a, the head 36a of the adjusting screw 36 may be formed thin. In this way, even if the through-hole 31c is not provided with a large-diameter through-hole portion, the protruding amount of the adjusting screw 36 can be made sufficiently small. Further, if a plus-type (or minus-type) groove, for example, is provided above the thinly formed head 36a, the adjusting screw 36 can be rotated using a general-purpose plus driver (or minus driver). It is convenient because it can. Further, a so-called flat head screw (a screw having a flat top surface and a conical head portion) may be used as the adjusting screw 36. Further, in this case, instead of providing a large-diameter through-hole portion in the insertion hole 31c, it is preferable to provide a recess (shape like a mortar) in accordance with the conical shape above the insertion hole 31c. Thereby, it is possible to suppress the protrusion of the adjusting screw 36 on the upper surface of the flange portion 31a while using a countersunk screw as the adjusting screw 36. The pair of adjusting screws 36 have a function of fixing the flanged short cylinder 31 to the upper blade body 1.

  The pivot part 3 has a thin cylindrical body 37 having a substantially cylindrical shape. The thin screw body 37 is formed with a male screw that engages with a female screw formed on the inner surface of the first screw hole 2c on the outer surface thereof. The thin screw body 37 that is screwed into the first screw hole 2 c comes into contact with the lower surface of the shaft body 32. Specifically, the thin screw body 37 is in contact with the lower surface of the large-diameter screw portion 32a. The thin screw body 37 forms a double screw structure together with the large-diameter screw portion 32a, and enables the shaft body 32 to be stably fastened.

  An opening 37a that exposes the first hexagonal hole 32b in a bottom view is formed at the center of the thin screw body 37. The opening 37a penetrates the thin screw body 37 in the vertical direction, and exposes the entire first hexagonal hole 32b. In the present embodiment, the opening 37a is substantially circular in a bottom view, but this is merely an example, and other shapes such as a rectangular shape may be used. The thin screw body 37 has a pair of engagement holes 37b so as to sandwich the opening 37a. Each engagement hole 37b is substantially circular in a bottom view, but this is an example, and other shapes such as a rectangular shape may be used. The engagement hole 37b is an example of the engagement portion of the present invention.

  Next, the effect of the pivot attachment part 3 comprised as mentioned above is demonstrated. FIG. 7 is a schematic perspective view showing an example of the adjusting tools 5 and 6 used for adjusting the pivoting portion 3 provided in the heel S according to the embodiment of the present invention. FIG. 8 is a schematic cross-sectional view illustrating a state in which the adjustment tools 5 and 6 illustrated in FIG. 7 are attached to predetermined positions of the pivot portion 3.

  The first adjuster 5 is a hexagon wrench. The first adjuster 5 is used by being inserted into a first hexagonal hole 32 b formed in the shaft body 32. The second adjuster 6 has a through hole 6a provided near one end of the plate-like main body part and a pair of convex parts 6b provided so as to sandwich the through hole 6a. The through-hole 6a and each convex part 6b are substantially circular in planar view. The diameter of the through hole 6a is set to a size that allows the first adjustment tool 5 to be inserted and rotated. The second adjuster 6 is used by inserting a pair of convex portions 6 b into a pair of engaging holes 37 b formed in the thin screw body 37.

  In the example shown in FIGS. 7 and 8, the first adjustment tool 5 is inserted into the through hole 6a of the second adjustment tool 6 and the opening 37a of the thin screw body 37, and the first hexagonal hole 32b. Inserted into. By rotating the first adjusting tool 5 and the second adjusting tool 6 as appropriate, the large-diameter screw portion 32a and the thin screw body 37 can be screwed or unscrewed to move the shaft body 32 up and down. The vertical distance between the flat portion 1a of the upper blade body 1 and the flat portion 2a of the lower blade body 2 can be adjusted by moving the shaft body 32 up and down. Because of the double screw structure using the large-diameter screw portion 32a and the thin screw body 37, fine adjustment of the distance between the two flat portions 1a and 2a can be performed stably, and the large-diameter screw portion 32a can be firmly screwed into the first screw hole 2c, and unintentional rotation of the large-diameter screw portion 32a due to long-term use of the collar S can be suppressed as much as possible. Further, in this example, since the opening 37a is formed in the thin screw body 37, it is not necessary to remove the thin screw body 37 for adjusting the shaft body 32, which is convenient.

  The procedure for adjusting the position of the shaft body 32 using the first adjusting tool 5 and the second adjusting tool 6 is arbitrary by the operator, but for example, the following procedure may be adopted. First, the shaft body 32 is adjusted to an ideal position using the first adjusting tool 5. Thereafter, using the second adjustment tool 6, the thin screw body 37 is screwed and firmly brought into contact with the lower surface of the large-diameter screw portion 32a. At this time, if the shaft body 32 is not fixed, the position-adjusted shaft body 32 may move due to friction with the thin screw body 37 or the like. Therefore, while the shaft body 32 is fixed so as not to move using the first adjusting tool 5, the thin screw body 37 is screwed using the second adjusting tool 6. According to this procedure, it is easy to firmly bring the thin screw body 37 into contact with the lower surface of the large-diameter screw portion 32a while keeping the shaft body 32 in an ideal position.

  The pivot part 3 has a pair of adjusting screws 36 as described above. Each adjusting screw 36 can be screwed or unscrewed with respect to the second screw hole 1d. In the present embodiment, for example, each adjustment screw 36 is screwed or unscrewed using a hexagon wrench. Moreover, it has a pair of protrusion 31 contact | abutted to the flat part 1a of the upper blade body 1 on the lower surface of the collar part 31a. If the fastening position of the pair of adjusting screws 36 with respect to the second screw hole 1d is made the same, the lower surface of the flange portion 31a can be made horizontal with respect to the flat portion 1a of the upper blade body 1. By varying the fastening position of each adjusting screw 36 with respect to the second screw hole 1d, the inclination angle of the lower surface of the flange portion 31a with respect to the flat portion 1a can be changed with the pair of protrusions 31 as fulcrums. That is, the pair of adjusting screws 36 can adjust the inclination angle in the longitudinal direction of the brazed short cylinder 31 with respect to the upper blade body 1 by using rotation about the pair of protrusions 37 (fulcrum portions). . The pair of adjusting screws 36 is an example of the adjusting portion of the present invention.

  The short tubular body 31 with a flange is integral with the lower blade body 2 via a shaft body 32. For this reason, the amount of inclination of the lower blade 2 relative to the upper blade 1 can be changed by adjusting the fastening position of the adjusting screw 36 with respect to the second screw hole 1d. That is, by adjusting each adjusting screw 36 while being screwed or screwed, the meshing pressure at the meshing portion of the pair of blade bodies 1 and 2 can be finely adjusted.

  The pivot portion 3 pivots the flat portion 1a of the upper blade body 1 and the flat portion 2a of the lower blade body 2 vertically with a small interval. For this reason, a user (such as a barber) of the bag S can perform a smooth opening / closing operation of the bag S over a long period of time. As described above, the fine adjustment of the small interval between the two flat portions 1a and 2b can be stably performed by the double screw structure. Also from this point, the saddle S is easy to ensure a smooth opening and closing operation over a long period of time.

Further, as described above, the pivotally attaching portion 3 can easily and accurately finely adjust the meshing pressure of the pair of blade bodies 1 and 2 using the pair of adjusting screws 36. For this reason, the pivot attachment part 3 can be adjusted to an appropriate state corresponding to the user's heel of the heel S. That is, it is possible to avoid the blade portion from being deformed by the pressure of hand-handling. Moreover, in the pivot part 3 of this embodiment, in order to adjust the meshing force, a member such as an elastic stabilizer (which is easily adopted in the conventional configuration) that easily generates distortion is not used. For this reason, the pivot part 3 of this embodiment can simplify a structure and can improve pressure resistance.

  The scissors set according to the embodiment of the present invention includes the scissors S of the present embodiment and a tool that adjusts the pivoting portion 3 of the scissors S. The above-described first adjusting tool 5 and second adjusting tool 6 may be included as tools for adjusting the pivoting portion 3. As a tool for adjusting the pivoting portion 3, in addition, a screwdriver used by being engaged with a plus groove or a minus groove provided on the head portion 35a of the tightening screw 35, or a hexagon wrench used for adjusting the adjusting screw 36. May be included.

Further, as a tool for adjusting the pivoting portion 3, a fixing base for placing and fixing the rod S for the adjustment of the pivoting portion 3 may be included. For example, the fixing base may fix the heel S in such a posture that the upper blade body 1 is at the bottom and the lower blade body 2 is at the top. By setting the heel S and the tool for adjusting the pivot portion 3 as a set, the user of the heel S can save time and labor for preparing the tool separately for adjusting the pivot portion 3.
