Description

Technical Field

[0001] One aspect of the present invention relates to a razor accessory. Background Technology

[0002] In recent years, the concept of "3Rs" has been promoted, encompassing the reduction of waste through the use of resources, the reuse of usable items, and the recycling of waste as a resource. Furthermore, the 17 targets in the UN Sustainable Development Goals (SDGs) include ensuring sustainable production and consumption patterns and significantly reducing waste generation. In this context, the razor industry also requires the development of environmentally conscious razors that meet the 3R criteria.

[0003] Additionally, Patent Document 1 discloses an adapter for connecting a razor handle and a razor case together. This adapter is configured to include a handle engaging portion, a case engaging portion, and a tongue member.

[0006] Patent Document 1: US Patent No. 11,052,558 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] Among the 17 Sustainable Development Goals (SDGs) adopted at the UN summit, Goal 12, "Responsible Consumption and Production," enumerates sustainable production and consumption patterns, requiring a significant reduction in waste generation. For example, Goal 12-5, as a target, outlines a significant reduction in waste generation by 2030 through prevention, reduction, recycling, and reuse. In this context, the razor industry also requires a reduction in waste generation.

[0009] The inventors have made efforts to improve the razor, including as one of the objectives listed in SGDs 12-5, to prevent the generation of waste. For example, this invention can suppress waste by enabling the razor handle to be used for an extended period.

[0010] In traditional razors, the design involves attaching a dedicated razor body case (also called the razor body or razor head) to the handle (stand). In this case, if the user wants to use a new razor body case, a special handle is required to mount it. Therefore, even if the user is considering using a new razor body case, there are financial and psychological barriers that make it difficult to readily try it. Furthermore, there is often a sense of guilt about discarding a usable handle.

[0011] If the adapter described in Patent Document 1 or a similar structure is used, the handle can be connected to a blade box other than a dedicated blade box, but the structure is complex and the adapter itself is easily damaged. In particular, the adapter in Patent Document 1 is based on a structure with a rocking mechanism having a tongue member. Therefore, the rocking mechanism, as a movable part, may break and become unusable, or dirt and debris from use may accumulate around the movable part, causing it to become immobile and malfunction.

[0012] Methods for solving problems

[0013] One aspect of the present invention is a razor accessory for enabling a razor handle having a connecting mechanism for connecting to a first razor body box to connect to a second razor body box having a different connecting mechanism than the first razor body box, wherein the razor accessory comprises:

[0014] A connecting hole, located at one end, allows the housing connecting portion of the second blade housing to be inserted and connected to the second blade housing; and

[0015] A handle connector is provided at the other end and can be connected to the handle.

[0016] The razor accessory with the above structure is designed to connect the second blade holder using a simple connection hole that does not include moving parts, thus making it a structure that is difficult to break or malfunction. Therefore, an accessory that can be used for an equally long period of time can be installed on a handle that can be used for a relatively long period of time, and the second blade holder can be used.

[0017] In other words, from the customer's perspective, there are no financial or psychological barriers to attaching the accessory to a handle that can be used for a long time, making it easy to try the aforementioned second blade case. Furthermore, since the handle can still be used, the second blade case can be used without feeling guilty. This allows for easy experimentation with other blade cases (second blade cases) that are not specifically designed for the handle (first blade case), expanding customer choices. Additionally, while the accessory's structure may appear simple at first glance and might seem like a specification downgrading, it can be manufactured relatively inexpensively, making it easy to popularize worldwide as a replacement blade case. Moreover, this accessory is a technological solution created based on an unprecedented new perspective, providing new value to customers and connecting with technological innovation in the razor industry.

[0018] In particular, in the appendix of this invention, since the structure for connecting the second blade holder to the appendix is ​​a hole, anyone can easily replace the razor simply by inserting the second blade holder, which serves as the replacement blade, into the hole. Furthermore, since a swing mechanism can be provided on the side of the second blade holder, which serves as the replacement blade, customers can select a replacement blade suitable for their razor, thereby providing new value to customers. This invention is a technical solution serving as a means to further popularize such new value.

[0019] Moreover, from the perspective of the SDGs, the ability to continue using usable handles without discarding them helps to reduce waste and contributes to creating a sustainable and better world.

[0020] In the above-mentioned razor accessories, it is preferable that the razor accessory is configured not to have movable parts.

[0021] The razor attachment based on the above structure, as a structure that eliminates movable components that are relatively easy to break or malfunction, can become a structure that can be used for a long time.

[0022] In the above-mentioned razor accessories, it is preferable that the handle connection portion is configured to be connected to a connection mechanism for connecting the first razor body box.

[0023] The razor accessory with the above structure can stably hold the accessory and the second blade box connected to the accessory by means of the handle, since the accessory is connected to the connecting function.

[0024] Of the aforementioned razor accessories, the preferred one is...

[0025] This razor accessory does not have a rocking mechanism that allows the second blade housing to tilt relative to the handle.

[0026] The second blade box has a blade and a rocking mechanism that allows the blade to tilt relative to the handle.

[0027] The razor accessory with the above structure is configured such that the accessory does not have a wobbling mechanism, while the second blade housing has a wobbling mechanism. As a result, an accessory that can be used for a long time can be provided, and the razor can be a structure with a wobbling mechanism.

[0028] In the above-mentioned razor accessory, it is preferable that the razor accessory further includes a tilting motion prevention part, which prevents the razor accessory from tilting relative to the handle.

[0029] The razor accessory with the above-described structure prevents the rocking mechanism, which is a movable member of the handle, from functioning, thus suppressing damage or malfunction of the movable member. Furthermore, when the second blade holder has a rocking mechanism, excessive tilting relative to the handle is prevented. Additionally, when the second blade holder does not have a rocking mechanism, it can be used as a handle without a rocking mechanism. In other words, the presence and range of motion of the rocking mechanism can be determined using the second blade holder.

[0030] In the above-mentioned razor accessory, it is preferable that the cross-section of the connecting hole in the plane orthogonal to the insertion direction of the connecting part of the box is formed such that the longitudinal length orthogonal to the extension direction of the blade held by the second blade box is larger than the lateral length.

[0031] According to the razor accessory with the above structure, since the connecting hole is intentionally made to be longer in the longitudinal direction than in the transverse direction, the handle can be prevented from obstructing the tilting movement of the second blade box when the second blade box tilts (rotates) and swings about the direction in which the handle extends.

[0032] In the aforementioned razor accessories, it is preferable that the first blade housing cannot be connected to the connecting hole.

[0033] In the above-mentioned razor accessories, it is preferable that the razor accessory is formed from a single component.

[0034] Razor attachments with the above structure can be made simpler and cheaper, and are more resistant to damage and can be used for a long time.

[0035] Additionally, one aspect of the present invention is a razor accessory assembly comprising the aforementioned razor accessory and the second blade housing, wherein...

[0036] The razor accessory does not have a rocking mechanism that allows the second blade housing to tilt relative to the handle.

[0037] The second blade box has a blade and a rocking mechanism that allows the blade to tilt relative to the handle. Attached Figure Description

[0043] The razor accessory of the present invention enables the handle of a conventional razor, which is designed to be connected to a dedicated razor case (i.e., a dedicated case), to be connected to and used with a razor case different from that dedicated case. Hereinafter, the razor accessory of the present invention will be specifically described with reference to the accompanying drawings. However, the embodiments described below are merely examples of the present invention and do not limit the scope of the invention. Furthermore, in the accompanying drawings, the same reference numerals are used to denote the same constituent elements, and their descriptions are sometimes omitted.

[0044] In this manual, razor accessories are sometimes simply referred to as "accessories." Razor accessories are sometimes also called "razor adapters" or simply "adapters." In this manual, as mentioned above, a dedicated razor body case designed to connect to the handle is sometimes referred to as a "dedicated case." On the other hand, an alternative razor body case connected using accessories is simply referred to as a "razor body case." The structure including accessories and a razor body case is referred to as a "razor accessory set" or "accessory set."

[0045] The x-axis, y-axis, and z-axis are shown in the accompanying drawings of this specification. These axes define the direction of the long side of the connecting hole as the "x-axis" and the direction of the short side as the "y-axis." The axis extending perpendicular to both the x-axis and y-axis, i.e., the direction of the box connection portion into which the tool body box is inserted into the connecting hole, is defined as the "z-axis." The y-axis extends along the direction in which the tool body is provided on the tool body box connected to the accessory. The x-axis, y-axis, and z-axis form a mutually orthogonal coordinate system. Sometimes the direction of the arrow on the x-axis is called the x-axis + side, and the direction opposite to the arrow is called the x-axis - side; the same applies to the other axes. Sometimes the z-axis + side and z-axis - side are referred to as the "back side" and "front side," respectively. The x-axis + side, and the side on which the tool body box is mounted on the handle, is called the "upper side," and the x-axis - side is called the "lower side."

[0046] <Overall Structure>

[0047] Figure 1 and Figure 2 This is a 3D view of razor accessory 1 and handle 2. Figure 1 This diagram shows the razor connected to handle 2 using accessory 1. Figure 2 This is a diagram showing the razor with accessory 1 separated from the handle 2.

[0048] Furthermore, the structure of the handle 2 varies depending on the razor, but for the sake of specific explanation, specific structural examples are given in this embodiment. However, as understood from the gist of the appendix according to the present invention, the structure of the handle 2 is not limited to the structure described in this embodiment and can be any structure. Similarly, the handle connection portion 11 of the attachment 1 connected to the handle 2 can also be replaced with a structure suitable for the connection mechanism of the handle 2.

[0049] <Controller 2>

[0050] Handle 2 is a conventional razor handle with a connecting mechanism for connecting to a dedicated razor case, i.e., a special case. Handle 2 has a gripping part 21 and a connecting part 22.

[0051] The grip 21 extends in a rod shape along the vertical direction and is held by the user when using the razor, which includes the handle 2.

[0052] The connecting part 22 was originally a connecting mechanism for connecting the special box to the handle 2, but it can also be connected to the handle connecting part 11 of the accessory 1. The connecting part 22 of the handle 2 in this embodiment has connecting parts 221 at both ends of the handle and a connecting part 222 at the center of the handle.

[0053] The handle end connecting portions 221 are provided at both ends of the upper end of the handle 2 in the width direction (y-axis direction) and are configured to be connected to the accessory end connecting portions 111 of the accessory 1. Each handle end connecting portion 221 has a cylindrical shaft-shaped portion that can be detachably inserted into the insertion hole provided in the accessory end connecting portion 111.

[0054] The handle central connecting part 222 is a Y-shaped member located at the center of the upper end of the handle 2 in the width direction, and is configured to connect with the accessory central connecting part 112 of the accessory 1. The handle central connecting part 222 uses its Y-shaped portion to detachably clamp the accessory central connecting part 112 from both ends in the width direction.

[0055] Furthermore, when the dedicated box is connected to the handle 2 of this embodiment, the dedicated box can tilt freely relative to the handle 2 (for specific structure and operation, please refer to Japanese Patent Application Publication No. 2005-218646). In contrast, the handle connection portion 11 of Appendix 1 includes two first tilting motion blocking portions 111a, two second tilting motion blocking portions 111b, and one third tilting motion blocking portion 112a to prevent Appendix 1 from tilting relative to the handle 2 (see...). Figure 3 The first tilting motion blocking part 111a and the second tilting motion blocking part 111b are formed at the two end connecting parts 111 of the accessory, and the third tilting motion blocking part 112a is formed at the central connecting part 112 of the accessory. These first tilting motion blocking parts 111a, second tilting motion blocking parts 111b and third tilting motion blocking parts 112a are collectively referred to as "tilting motion blocking parts".

[0056] The first tilting motion preventing part 111a, the second tilting motion preventing part 111b, and the third tilting motion preventing part 112a are contact surfaces that abut against a predetermined surface of the handle 2, and function to prevent the accessory 1 from tilting relative to the handle 2 by abutting against the predetermined surface of the handle 2. Figure 2 In this design, the first tilting motion preventing part 111a and the third tilting motion preventing part 112a prevent the attachment 1 from tilting forward relative to the handle 2, while the second tilting motion preventing part 111b prevents the attachment 1 from tilting opposite relative to the handle 2. That is, the attachment 1 will not tilt relative to the handle 2, while the blade housing 3 connected to the attachment 1 tilts itself, as described later. Thus, by providing the tilting motion preventing parts, it is possible to suppress excessive tilting of the blade housing 3 relative to the handle 2 and avoid unstable movements. Alternatively, the tilting motion preventing parts can function in a way that limits the attachment 1 from tilting excessively relative to the handle 2.

[0057] <Attachment 1>

[0058] Figure 3 and Figure 4 This is an enlarged view of Annex 1. Annex 1 is a component for connecting the blade box 3, which has a different connecting mechanism than the dedicated box, to the handle 2. Annex 1 has a handle connecting part 11 provided at the lower end and a connecting hole 12 provided at the upper end. Annex 1 is formed of resin or metal, or resin and metal, and preferably is formed of a single component. Annex 1 in this embodiment is configured not to have movable components such as a rocking mechanism for tilting the blade box 3.

[0059] The handle connecting part 11 can be connected to the connecting part 22 of the handle 2. The handle connecting part 11 has two end connecting parts 111 and a central connecting part 112.

[0060] The accessory end connecting portions 111 are provided at both ends of the lower end of accessory 1 in the width direction, and are positioned corresponding to the handle end connecting portions 221 of handle 2. The accessory end connecting portions 111 are configured to connect with the handle end connecting portions 221. Each accessory end connecting portion 111 has a through hole into which the shaft-like portion of the handle end connecting portion 221 is inserted. The accessory end connecting portions 111 have two first tilting motion preventing portions 111a and two second tilting motion preventing portions 111b that prevent accessory 1 from tilting relative to handle 2.

[0061] The accessory central connecting part 112 is a columnar member located at the center of the lower end of accessory 1 in the width direction, extending perpendicular to both the width and vertical directions. The accessory central connecting part 112 is held by the handle central connecting part 222. The accessory central connecting part 112 has a third tilting motion preventing part 112a that prevents accessory 1 from tilting relative to handle 2.

[0062] As described above, the two first tilting motion blocking parts 111a, the two second tilting motion blocking parts 111b, and the third tilting motion blocking part 112a function as tilting motion blocking parts to prevent the accessory 1 from tilting relative to the handle 2.

[0063] The connecting hole 12 is a through hole with an opening 12a on the back side and an opening 12b on the front side. The tool body box 3 can be connected by inserting the box connector 6 of the tool body box 3 into the connecting hole 12. The cross-section of the connecting hole 12 at the xy plane, which is orthogonal to the insertion direction of the box connector 6 (i.e., the z-axis direction), is formed such that the longitudinal direction is longer than the transverse direction. The opening 12a on the back side of the connecting hole 12 is approximately rectangular, and the opening 12b on the front side is approximately trapezoidal, with the upper side expanding relative to the lower side and curving upwards.

[0064] Attachment 1 has a connecting surface 14, a stepped surface 15, a lower inner surface 16, and a protrusion 17 inside the connecting hole 12. The stepped surface 15 is a surface that is recessed from the outer edge surface 13 of Attachment 1 and formed along the xy plane. The connecting surface 14 is a surface that connects the outer edge surface 13 and the stepped surface 15 and is formed along the yz plane. The lower inner surface 16 is a surface formed on the lower side of the connecting hole 12. The lower inner surface 16 has a portion that abuts against the lower surface of the cantilever beam spring 63 in the box connecting part 6 of the blade box 3 and an inclined surface that slopes downward from this portion toward the front side. This inclined surface is the portion that abuts against the lower end of the engaging / disengaging part 64 when the guide part 62, the cantilever beam spring 63, the engaging / disengaging part 64, and the operating part 65 are inserted into the connecting hole 12 to connect Attachment 1 to the blade box 3. Because the lower surface 16 inside the hole is inclined in this way, the connecting hole 12 becomes a tapered shape in the longitudinal direction from the front side to the back side.

[0065] A pair of protrusions 17 are formed facing each other along the y-axis, protruding from the z-axis+ side of the connecting hole 12 toward the z-axis- side. When the blade housing 3 is connected to the accessory 1, the protrusions 17 face the back side end faces 6a of the right plate portion 62b and the left plate portion 62c of the blade housing 3. In this embodiment, the protrusions 17 are configured not to abut against the back side end faces 6a of the right plate portion 62b and the left plate portion 62c, but they may also be configured to abut against each other.

[0066] <Knife Box 3>

[0067] Figure 5 This figure shows the blade housing 3 connected to Annex 1. As shown, the blade housing 3 is configured to include a blade assembly 4, an elastic support 5, and a housing connection portion 6. Furthermore, the blade housing 3 connected to Annex 1 is not limited to the structure of this embodiment.

[0068] <Knife Assembly 4>

[0069] The knife assembly 4 is configured to include five blades 41 and a frame 42 that holds these blades 41. The blades 41 extend along the y-axis. The front end face of each blade 41 forms a blade tip and is exposed on the front side. The blade tip face of the multiple blades 41 is the skin contact surface that comes into contact with the user's skin. The blades 41 are subjected to force towards the front side, thus preventing excessive pressure on the user's skin. The number of blades 41 can be arbitrarily changed.

[0070] The frame 42 is formed of a hard resin such as ABS resin, but is not limited to this. In this embodiment, the frame 42 is formed by connecting multiple components. However, the frame 42 may also be formed of a single component. The frame 42 has an opening that is open on the front side, through which the tip of the blade 41 protrudes. A limiting part (not shown) extending toward the rear side is provided on the rear side of the frame 42. The limiting part (not shown) restricts the tilting movement of the blade assembly 4 to a certain extent.

[0071] <Elastic Support 5>

[0072] The elastic support 5 is formed of a flexible material such as soft resin or rubber, and is configured to include a connecting portion 5c, a flexible portion 5b, and a pair of left and right connecting portions 5d. The elastic support 5 is provided on the back side of the razor assembly 4. The connecting portion 5c of the elastic support 5 is located on the back side of the central portion of the razor assembly 4 and is connected to the razor assembly 4. A pair of flexible portions 5b extend from the connecting portion 5c to the left and right. The pair of flexible portions 5b are connected to the frame 42 via the left and right connecting portions 5d. The left and right connecting portions 5d are fixed to the frame 42, and the connecting portion 5c is connected to the frame 42 in a manner that allows tilting movement mainly in the xz plane. By bending the flexible portion 5b of the elastic support 5, the razor assembly 4 can tilt relative to the attachment 1. Thus, by tilting the skin contact surface of the razor body 41, the razor with the attachment 1 installed can perform a swinging function.

[0073] The upper end face of the elastic support 5 is an inclined surface that slopes downwards towards the front side. The inclined blade assembly 4 restricts its tilting movement by abutting against the upper end of the elastic support 5. That is, the upper end of the elastic support 5 is a tilting movement limiting mechanism that restricts the tilting movement of the blade assembly 4 to a certain extent or more. The inclined surface of the upper end of the elastic support 5 has an inclination angle that makes surface contact with the contact surface of the blade assembly 4 when it abuts against it.

[0074] <Box Connector 6>

[0075] The box connecting part 6 is configured to include a main body part 61, a guide part 62, a cantilever beam spring 63, a locking / unlocking part 64, an operating part 65, and a plate-shaped part 66. The guide part 62, the cantilever beam spring 63, the locking / unlocking part 64, and the operating part 65 are inserted into the connecting hole 12 when the blade box 3 is connected to the accessory 1. The box connecting part 6 is formed of a hard resin such as ABS resin. The box connecting part 6 is preferably formed of a single component, but at least the cantilever beam spring 63 and the locking / unlocking part 64 are formed to be elastically deformable.

[0076] The main body 61 is the upper and front-side portion of the box connector 6, connected to the elastic support 5 and the guide portion 62. The guide portion 62 is located below the main body 61 and extends towards the rear side. The guide portion 62 and the cantilever beam spring 63 are configured such that their respective front-side ends do not protrude beyond the front-side edge 18 of the attachment 1. That is, in the box connector 6, the structure other than the main body 61 does not protrude beyond the front-side edge 18 of the attachment 1.

[0077] The guide portion 62 is configured to include an upper plate portion 62a, a right plate portion 62b, and a left plate portion 62c formed symmetrically to the right plate portion 62b. The guide portion 62 forms a U-shape in the cross section of the xy plane through the upper plate portion 62a, right plate portion 62b, and left plate portion 62c. The front side portion of the guide portion 62 extends downward compared to the back side portion. In this embodiment, the back side of the guide portion 62 is open, but it can also be a shape with a bottom surface. However, if the back side of the guide portion 62 is open, there is no bottom surface at the position opposite the operating portion 65. Therefore, the operating portion 65 can be elastically deformed more, and thus, it is sometimes easier to load and unload the blade box 3 relative to the accessory 1. The upper plate portion 62a, right plate portion 62b, and left plate portion 62c of the guide portion 62 face the inner side of the connecting hole 12 and abut against it, depending on the situation. When the tool body box 3 wants to move relative to the attachment 1 along the x-axis or y-axis, the movement is restricted by having the guide portion 62 abut against the inner surface of the connecting hole 12. Similarly, when the tool body box 3 wants to rotate relative to the attachment 1 in the xy-plane about the z-axis, the rotation is also restricted by having the guide portion 62 abut against the inner surface of the connecting hole 12.

[0078] A pair of plate-shaped portions 66 protrude to the right and left from the right plate portion 62b and left plate portion 62c of the guide portion 62, respectively. The front side surface of the plate-shaped portion 66, together with the front side end faces of the right plate portion 62b and left plate portion 62c, forms a plane parallel to the xy plane. The back side surface 66a of the plate-shaped portion 66 faces the front side edge portion 18 of the attachment 1. When the blade box 3 is connected to the attachment 1, the back side surface 66a of the plate-shaped portion 66 abuts against the edge portion 18. By abutting the back side surface 66a against the edge portion 18, the movement of the blade box 3 relative to the attachment 1 in the z-axis direction is restricted, and the attachment 1 and the blade box 3 are stably connected in the z-axis direction without wobbling.

[0079] Furthermore, in the structure of this embodiment, as described above, the movement of the blade box 3 relative to the attachment 1 in the z-axis direction is restricted by having the plate-shaped portion 66 abut against the attachment 1 in the z-axis direction. However, it is also possible to configure the attachment 1 and the blade box 3 to abut against each other in the z-axis direction using different portions.

[0080] A cantilever beam spring 63 is positioned at the lower end of the blade assembly 4 in the vertical direction (x-axis direction), with a portion of its front end supported between the right plate portion 62b and the left plate portion 62c. The cantilever beam spring 63 is formed to extend towards the rear side. The front end of the cantilever beam spring 63 is a fixed end, and the rear end is a free end. An operating part 65 extending in the vertical direction is provided at the free end of the cantilever beam spring 63, i.e., the rear end. A locking / unlocking part 64 is provided below the operating part 65. The lower surface of the locking / unlocking part 64 is positioned opposite the connecting surface 14 and does not protrude from the opening 12a on the rear side of the connecting hole 12. That is, the side surface (y-axis direction) of the lower end of the locking / unlocking part 64 is covered by the attachment 1.

[0081] The back side surface of the operating part 65 is curved toward the back side as it moves toward the upper side, and the area near its upper end becomes the pressing surface 65a. At least a portion of the pressing surface 65a of the operating part 65 is exposed on the back side of the connecting hole 12. The operating part 65 is formed to be longer in the longitudinal direction than in the transverse direction.

[0082] <Attachment 1 and Tool Box 3 Installation and Removal Procedure>

[0083] When the box connector 6 is inserted into the connector hole 12 and locked in the locked state, if the user presses the pressing surface 65a towards the z-axis side, the operating part 65 and the cantilever beam spring 63 elastically deform, the pressing surface 65a moves towards the z-axis side, and the lower end of the engagement release part 64 tilts towards the z-axis + side while moving towards the x-axis + side. As a result, the engagement release part 64 becomes a state in which it is offset towards the x-axis + side (upper side) compared to the step surface 15 in the x-axis direction, and the engagement release part 64 crosses the step surface 15 towards the z-axis side (front side). Thus, the locked state of the cantilever beam spring 63 and the engagement release part 64 is released into a non-locked state.

[0084] On the other hand, when the box connecting part 6 of the blade box 3 is disengaged from the connecting hole 12 and is not locked, the user inserts the guide part 62, cantilever beam spring 63, engagement / disengagement part 64, and operating part 65 of the box connecting part 6 in the blade box 3 into the connecting hole 12 when connecting the blade box 3 to the accessory 1. At this time, the lower end of the engagement / disengagement part 64 abuts against the inclined surface of the lower surface 16 inside the hole, the upper plate part 62a of the guide part 62 abuts against the upper surface 19 inside the hole, the cantilever beam spring 63 flexes toward the x-axis + side (upper side), and the engagement / disengagement part 64 moves toward the x-axis + side. Furthermore, when the cantilever beam spring 63 and the engaging / disengaging part 64 are inserted towards the z-axis + side (back side), causing the engaging / disengaging part 64 to move across the step surface 15 towards the z-axis + side (back side), the cantilever beam spring 63, which flexes towards the x-axis + side (upper side), moves towards the x-axis - side (lower side) by force, and the engaging / disengaging part 64 also moves towards the x-axis - side (lower side). Thus, the engaging / disengaging part 64 and the cantilever beam spring 63 are locked in a locked state against the step surface 15. Therefore, the tool body box 3 is locked and connected to accessory 1.

[0085] <The swinging motion of the knife assembly 4 relative to accessory 1>

[0086] In this embodiment, as explained, a rocking motion is possible to tilt the knife assembly 4 relative to attachment 1. In the knife assembly 4, the flexible portion 5b of the elastic support 5 is designed to elastically deform so that the skin contact surface of the knife body 41 is parallel to the contact surface. The range of the tilting angle of the knife assembly 4 is determined by the contact surface between the limiting portion on the back side of the frame 42 and the main body 61, and the contact surface between the upper end of the elastic support 5 and the frame 42. When the limiting portion of the knife assembly 4 contacts the main body 61, further downward tilting of the upper end of the knife assembly 4 is restricted; when the contact surface 42a on the back side of the frame 42 contacts the upper end of the elastic support 5, further upward tilting of the lower end of the knife assembly 4 is restricted.

[0087] As described above, Appendix 1 does not have a rocking mechanism that causes the blade box 3 to tilt relative to the handle 2, and it does have a tilting motion blocking part that prevents the blade box 3 from tilting relative to the handle 2. On the other hand, the blade box 3 has a rocking mechanism that causes the blade 41 of the blade assembly 4 to tilt relative to the handle 2.

[0088] <Variation Example>

[0089] Annex 1 of the above-described embodiment can be configured to have different handle connection parts depending on each handle that is the object of connection.

[0090] In a modified example, the accessory may be configured to replace the handle connection part 11 in accessory 1 of the embodiment, and have a handle connection part capable of connecting to a dedicated blade box corresponding to the handle. The handle connection part of the modified example may have, for example, a handle insertion hole or connection mechanism capable of connecting to a handle different from the handle 2 of the embodiment.

[0091] <Features of the Implementation Method>

[0092] The above-described embodiment, with examples of implementation and variations, has the following features in its appendix 1.

[0093] Annex 1 is an accessory for connecting a razor handle 2, which has a connecting mechanism for connecting to a dedicated razor body case, to a razor body case 3, which has a different connecting mechanism than the dedicated razor body case. Annex 1 includes a connecting hole 12 and a handle connecting part 11. The connecting hole 12 is located at the upper end and is a hole through which the case connecting part 6 of the razor body case 3 can be inserted and connected to the razor body case 3. The handle connecting part 11 is located at the lower end and can be connected to the handle 2.

[0094] Because this accessory 1 is configured to connect to the blade box 3 using a simple connecting hole 12, it becomes a structure that is difficult to break. Therefore, the accessory 1, which can be used for a relatively long period of time, can be installed on the handle 2, and the blade box 3 can be used for the same long period of time.

[0095] Furthermore, since Annex 1 is constructed without movable components, it is a structure that eliminates movable components that are relatively easy to break or malfunction, and can be used for a long time.

[0096] In addition, the handle connecting part 11 of Annex 1 is configured to be connected to a connecting mechanism for connecting a dedicated blade box.

[0097] Furthermore, Annex 1 does not have a rocking mechanism that tilts the blade housing 3 relative to the handle 2. The blade housing 3 has a blade 41 and a rocking mechanism that tilts the blade 41 relative to the handle 2. Thus, Annex 1 can be constructed as a single component without a rocking mechanism as a movable member and an assembly part for assembling the rocking mechanism. Therefore, it can be configured to suppress malfunctions caused by damage and accumulation of dirt and debris in the movable member and assembly part, enabling long-term use of Annex 1 and providing a structure with a rocking mechanism as a razor.

[0098] In addition, Attachment 1 includes a tilting motion preventing part, which prevents Attachment 1 from tilting relative to the handle 2. This prevents the tilting motion mechanism of the handle 2 from functioning and suppresses damage or malfunction of the movable part.

[0099] In addition, the configuration is such that the dedicated blade box cannot be connected to Annex 1.

[0100] Furthermore, in Annex 1, the cross-section of the connecting hole 12 in the plane orthogonal to the insertion direction of the connecting portion 6 is formed such that the longitudinal length orthogonal to the extension direction of the blade 41 held by the blade box 3 is larger than the lateral length. Thus, by intentionally making the connecting hole 12 longer in the longitudinal direction than in the lateral direction, the handle 2 is prevented from obstructing the tilting movement of the blade box 3 when the blade box 3 tilts (rotates) and swings about the direction in which the handle 2 extends.

[0101] Furthermore, since Annex 1 is formed from a single component, it can be constructed to be simpler and cheaper, and is more difficult to break and can be used for a long time.

[0102] Additionally, the present invention includes a razor accessory assembly comprising accessory 1 and razor body box 3.
