[0004] Recently, as part of efforts to protect the environment, there has been a demand for the effective use of wood in various fields. However, when trying to use wood as a material for lever-type door handles, it is difficult to make the entire door handle out of wood. For this reason, it is considered to use only the handle portion of the door handle made of wood and the shaft portion made of another material, such as metal.

[0005] However, while conventional technologies relate to door handles in which the handle and shaft are separate components, the following problems exist when attempting to apply these technologies to door handles with wooden handles. First, wooden handles deteriorate over time, so while there is a desire to be able to replace the handle, conventional technologies do not take this into consideration. Also, wooden handles are more difficult to process with high precision than metal or resin handles, so it is difficult to apply conventional technologies to wooden handles.

[0006] The present invention has been made in view of the above points, and has as its object to easily provide a door handle having a handle formed of wood. [Means for solving the problem]

[0008] In the present invention, it is preferable that the screw hole portion is formed in the engaged portion so as to face the engaging portion, and the insertion hole is formed in the engaging portion so as to face the engaged portion.

[0009] In the present invention, it is preferable that the screw hole portion has a hole body formed in the engaged portion from the outer peripheral surface toward the center, and an insert nut that engages with the hole body and can be screwed onto the male thread of the screw member.

[0010] In the present invention, it is preferable that the engaged portion has a convex or concave shape, and the engaging portion has a concave or convex shape corresponding to the engaged portion. [Effects of the Invention]

[0019] [First embodiment] Fig. 1 is a perspective view of a door handle 1 according to a first embodiment of the present invention, seen from the handle portion 10 side. Fig. 2 is a perspective view of the door handle 1, seen from the mounting portion 22 side. Fig. 3 is an exploded perspective view of the door handle 1 according to the first embodiment.

[0020] In the following description, for convenience, the longitudinal direction (x-axis direction) of the handle portion 10 of the door handle 1 shown in Figures 1 to 3 will also be referred to as the width direction or left-right direction. Also, in the following description, the longitudinal direction (y-axis direction) of the square hole 222 for inserting a square core (not shown) into the shaft portion 20 of the door handle 1 will also be referred to as the front-rear direction or depth direction. The y-axis direction is the thickness direction of the door (not shown) to which the door handle 1 is attached. Also, in the following description, the direction perpendicular to both the x-axis direction and the y-axis direction (z-axis direction) will be referred to as the up-down direction, vertical direction, or height direction.

[0021] As shown in Figures 1 to 3, door handle 1 includes handle 10 and shaft 20. In door handle 1, handle 10 is longer than shaft 20, and one end 16 of handle 10 and one end 26 of shaft 20 are joined at a right angle or approximately a right angle, for example. That is, in door handle 1, handle 10 and shaft 20 are formed in an L-shape or approximately an L-shape. In door handle 1, shaft 20 is attached to a door in order to operate a box-shaped locking device (case lock) (not shown) provided on the door.

[0022] The handle 10 is made of wood. The handle 10 is the part that is gripped by the operator who opens or closes the door. The handle 10 is formed, for example, in a cylindrical or approximately cylindrical shape, with circular or approximately circular bottom surfaces 19 on one end 16 and the other end 17, and an outer peripheral surface 18, which is a side surface between the bottom surfaces 19. The handle 10 includes an engaged portion 11 and a screw hole portion 12.

[0023] The engaged portion 11 is the portion of the handle 10 that engages with the shaft 20. The engaged portion 11 is provided on one end 16 of the handle 10 in the longitudinal direction. Specifically, the engaged portion 11 is the outer peripheral surface 18 of the surface of the handle 10 on the one end 16 side. The engaged portion 11 engages with an engaging portion 21 of the shaft 20, which will be described later.

[0024] The threaded hole portion 12 is provided in the engaged portion 11. The threaded hole portion 12 is composed of, for example, a hole body 13 and an insert nut 14. The hole body 13 is a hole formed in the engaged portion 11 from the outer circumferential surface 18 toward the center in the radial direction so as to face the insertion hole 23 of the engaging portion 21 provided in the shaft portion 20. A counterbore portion 15 may be provided around the periphery of the hole body 13 on the outer circumferential surface 18 side.

[0025] The insert nut 14 is a cylindrical or approximately cylindrical member that can engage with the hole body 13 and be threaded onto the male thread of the screw member. The insert nut 14 has a plurality of protrusions on its cylindrical or approximately cylindrical outer peripheral surface that engages with the inner peripheral surface of the hole body 13. The protrusions on the outer peripheral surface of the insert nut 14 bite into the inner peripheral surface of the hole body 13. The insert nut 14 also has a female thread on its cylindrical or approximately cylindrical inner peripheral surface that screws onto the male thread.

[0026] The screw hole portion 12 is not limited to being composed of the hole body 13 and the insert nut 14 as described above, and may, for example, be configured so that the male thread of the screw member is directly screwed into the hole body 13 without the insert nut 14.

[0027] The shank 20 is the portion of the door handle 1 that is attached to the door. The shank 20 is formed from a material other than wood, for example, metal. The shank 20 is formed, for example, in a cylindrical or approximately cylindrical shape, having circular or approximately circular bottom surfaces 29 on one end 26 and the other end 27, and an outer peripheral surface 28 that is a side surface between the bottom surfaces 29. The shank 20 has a shorter longitudinal dimension than the handle 10. The shank 20 has an engagement portion 21, an attachment portion 22, and an insertion hole 23.

[0028] Engaging portion 21 is the portion of shaft 20 that engages with handle 10. Engaging portion 21 is provided on one end 26 of shaft 20 in the longitudinal direction. Specifically, engaging portion 21 is provided on the outer peripheral surface 28 of shaft 20 on the one end 26 side. Since engaging portion 21 can receive engaged portion 11, which is part of outer peripheral surface 18 that is cylindrical or approximately cylindrical, it is formed in a concave shape corresponding to the convex shape of engaged portion 11. An insertion hole 23 is provided in engaging portion 21.

[0029] The insertion hole 23 is a through-hole provided between the engaging portion 21 and the outer peripheral surface 28 on the opposite side in the radial direction to allow a screw member to be inserted therethrough. The insertion hole 23 is composed of a deep countersunk portion 231, which is a deep countersunk hole provided on the outer peripheral surface 28 on the opposite side and capable of accommodating the screw head of a screw member, and an insertion hole main body 232 into which the male thread portion of the screw member can be inserted. The insertion hole 23 is formed so that, when the engaging portion 21 and the engaged portion 11 are faced to each other, the axis passing through the center thereof becomes an axis Z1 which coincides or approximately coincides with the axis passing through the centers of the hole main body 13 and the insert nut 14 which constitute the screw hole portion 12.

[0030] The mounting portion 22 is a portion of the shaft portion 20 that is attached to the surface of a door (not shown) in order to attach the door handle 1 to the door. The mounting portion 22 is provided on a bottom surface 29 on the other longitudinal end 27 side of the shaft portion 20. The mounting portion 22 has a fitting portion 221 that protrudes outward in the longitudinal direction from the bottom surface 29, and a square hole 222 provided in the fitting portion 221.

[0031] The fitting portion 221 is fitted into a mounting hole for mounting the door handle 1 (not shown) provided on the door. The square hole 222 is a hole for inserting a square core (not shown) for operating the latch of the door case lock. By fitting the fitting portion 221 into the mounting hole and inserting the square core into the square hole 222, the latch of the door case lock can be operated by the door handle 1 to open and close the door.

[0032] <Action and effect> In the door handle 1 described above, the shaft 20 attached to the door and the handle 10 made of wood are fixed together with a screw member. In the door handle 1, the engaged portion 11 provided on the outer peripheral surface 18 of the handle 10 at one end 16 engages with the engaging portion 21 provided on the outer peripheral surface 28 of the shaft 20 at one end 26, so that the handle 10 made of wood and the shaft 20 made of a material other than wood function as a single door handle 1. Here, the engaging portion 21 is formed to be able to accommodate the shape of the engaged portion 11. The engaged portion 11 has a screw hole 12 that screws into a screw member. The shaft 20 has an attachment portion 22 at the other end 27 for attachment to the door and an insertion hole 23 through which a screw member can be inserted into the engaging portion 21.

[0033] According to the above configuration, the door handle 1 allows for easy replacement of the handle 10 because the engaging portion 21 provided on the shaft 20 has a shape that can accommodate the shape of the engaged portion 11 provided on the handle 10, that is, a shape that can fit with the engaged portion 11. Furthermore, the door handle 1 allows for the engaged portion 11 provided on the handle 10, which is made of wood and is therefore more difficult to process with high precision compared to metal or resin handles, to have a simpler shape than the engaging portion 21.

[0034] Therefore, according to the door handle 1 described above, it is possible to easily provide the handle portion 10 made of wood.

[0035] Furthermore, in the door handle 1, the screw hole 12 is formed to face the engaging portion 21 in the engaged portion 11, and the insertion hole 23 is formed to face the engaged portion 11 in the engaging portion 21, so that the axes passing through the centers of each coincide or nearly coincide as Z1. Therefore, according to the door handle 1, the handle portion 10 can be easily replaced, and it is possible to provide a handle portion 10 that is easily made of wood.

[0036] Furthermore, the door handle 1 has a hole body 13 in which the screw hole portion 12 is formed from the outer peripheral surface 18 toward the center at the engaged portion 11, and an insert nut 14 that engages with the hole body 13 and can be screwed onto the male thread of the screw member, which makes it easy to replace the handle portion 10 and also makes it easy to process the handle portion 10 which is made of wood.

[0037] Furthermore, according to the door handle 1, by forming the shape of the engaging portion 21 to correspond to the engaged portion 11, for example, to a concave shape, it is possible to easily process the handle portion 10 made of wood.

[0038] 3. Other embodiments [Second embodiment] A door handle 1B according to a second embodiment of the present invention will be described below. Only the configurations different from the door handle 1 according to the first embodiment will be described below.

[0039] Fig. 4 is a perspective view of a door handle 1B according to the second embodiment of the present invention, viewed from the side of the attachment portion 22. Fig. 5 is an exploded perspective view of the door handle 1B.

[0040] As shown in Figures 4 and 5, the door handle 1B according to the second embodiment of the present invention differs from the door handle 1 described above in the shapes of the handle 10B and the shaft 20B. Specifically, in the door handle 1B, the handle 10B is formed in a rectangular or approximately rectangular prism shape, having rectangular or approximately rectangular bottom surfaces 19B at one end 16 and the other end 17, and an outer peripheral surface 18B that is four side surfaces between the bottom surfaces 19B. The shaft 20B is also formed in a rectangular or approximately rectangular prism shape, having rectangular or approximately rectangular bottom surfaces 29B at one end 26 and the other end 27, and an outer peripheral surface 28B that is four side surfaces between the bottom surfaces 29B.

[0041] Like the door handle 1 described above, the door handle 1B has a shaft 20B attached to the door and a handle 10B made of wood fastened together with a screw member. In the door handle 1B, an engaged portion 11 provided on an outer peripheral surface 18B at one end 16 of the handle 10B engages with an engaging portion 21 provided on an outer peripheral surface 28B at one end 26 of the shaft 20B, and the handle 10B made of wood and the shaft 20B made of a material other than wood function as a single door handle 1B.

[0042] The door handle according to the present invention is not limited to a cylindrical or approximately cylindrical shape like the handle 10 and shaft 20 described above, as long as the engaging portion 21 provided on the shaft 20B has a shape that can accommodate the shape of the engaged portion 11 provided on the handle 10B, that is, a shape that can fit with the engaged portion 11. In other words, the door handle according to the present invention may be a square prism or approximately square prism like the handle 10B and shaft 20B of the door handle 1B, or may have any other shape.

[0043] According to the door handle 1B described above, the handle portion 10B can be easily replaced, just like the door handle 1. Furthermore, the door handle 1B allows the engaged portion 11 provided on the handle portion 10B, which is made of wood and is more difficult to process with high precision compared to metal or resin handles, to have a simpler shape than the engaging portion 21.

[0044] Therefore, according to the door handle 1B described above, similar to the door handle 1 described above, it is possible to provide the handle portion 10B which is easily formed from wood.

[0045] [Third embodiment] A door handle 1C according to a third embodiment of the present invention will be described below. Only the configurations that differ from the door handles 1 and 1B according to the first and second embodiments will be described below.

[0046] Fig. 6 is a perspective view of a door handle 1C according to the third embodiment of the present invention, viewed from the side of the attachment portion 22. Fig. 7 is an exploded perspective view of the door handle 1C.

[0047] As shown in Figures 6 and 7, a door handle 1C according to the third embodiment of the present invention differs from the door handles 1 and 1B described above in the shapes of a handle portion 10C and a shaft portion 20C. Specifically, the door handle 1C differs in that the engaged portion 11 of the handle portion 10C is formed in a concave shape relative to the outer peripheral surface 18 of the handle portion 10C. Also, in the door handle 1C, the engaging portion 21 of the shaft portion 20 is formed in a convex shape relative to the concave engaged portion 11, thereby being formed in a shape that can receive the engaging portion 21. In the door handle 1C, the shapes of the bottom surfaces 29C on one end 26 side and the other end 27 side of the shaft portion 20 are different.

[0048] The door handle of the present invention is not limited to the shapes of the convex engaged portion 11 and concave engaged portion 21 in the above-mentioned door handles 1, 1B, but may also have a concave engaged portion 11 and convex engaged portion 21 as in door handle 1C, as long as the engaging portion 21 provided on shaft portion 20B has a shape that can accept the shape of the engaged portion 11 provided on handle portion 10B, that is, a shape that can fit into the engaged portion 11.

[0049] Like the door handles 1 and 1B described above, the door handle 1C has a shaft 20C attached to the door and a handle 10C made of wood that are fixed with screws. In the door handle 1C, an engaged portion 11 provided on an outer peripheral surface 18C at one end 16 of the handle 10C engages with an engaging portion 21 provided on an outer peripheral surface 28C at one end 26 of the shaft 20C, and the handle 10C made of wood and the shaft 20C made of a material other than wood function as a single door handle 1.

[0050] According to the door handle 1C described above, the handle portion 10C can be easily replaced, just like the door handles 1 and 1B. Furthermore, the door handle 1C is made of wood, which is more difficult to process with high precision compared to metal or resin handles, and the engaged portion 11 provided on the handle portion 10C can be made into a simpler shape than the engaging portion 21.

[0051] Therefore, according to the door handle 1C described above, similar to the door handles 1 and 1B described above, it is possible to provide a handle portion 10C that is easily formed from wood.

[0052] In addition, those skilled in the art can appropriately modify the switching device of the present invention in accordance with conventionally known knowledge. As long as such modifications still include the configuration of the present invention, they are of course included in the scope of the present invention. [Explanation of symbols]
