DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The door handle according to the embodiment of the present invention will be described in detail below with reference to the drawings. Note that the embodiment described below is a preferred specific example for carrying out the present invention, and therefore various technical limitations are imposed thereon. However, the present invention is not limited to this embodiment unless otherwise specified in the following description to limit the invention. <Embodiment> A door handle according to an embodiment of the present invention will be described below with reference to Figs. 1 to 6. Fig. 1 is an overall perspective view showing a door handle according to an embodiment of the present invention. Fig. 2 is an exploded perspective view showing the door handle of Fig. 1. Fig. 3 is a side view showing the door handle of Fig. 1. Fig. 4(a) is a side view showing the details of the base. Fig. 4(b) is a front view showing the details of the base. Fig. 5(a) is a front view showing the details of the first handle. Fig. 5(b) is a cross-sectional view taken along the line AA of Fig. 5(a). Fig. 6 is an exploded perspective view showing the installation process of the door handle of Fig. 1.

[0014] 1 and 2, the door handle according to the embodiment includes a first handle 10, a second handle 20, a base 30, at least one engagement protrusion 40, an engagement groove portion 50, and a fixing means 60. The outer shape of the first handle 10 and the second handle 20 is a quadrangular pyramid shape with a square base.

[0015] As shown in Fig. 3, the first handle 10 is disposed on one of the exterior side and interior side of the door 1, and the second handle 20 is disposed on the other side. In this embodiment, the door 1 is a glass hinged door, and the first handle 10 is disposed on the pull side of the door 1, and the second handle 20 is disposed on the push side of the door 1. Although this cannot be generally stated depending on the structure of the building, the pull side of the door 1 is often regarded as the exterior side of the door 1, and the push side of the door 1 is often regarded as the interior side of the door 1. Also, as shown in Fig. 3, a first height L1 of the first handle 1 from the door 1 is made higher than a second height L2 of the second handle 20 from the door 1.

[0016] 2 and 4, the base 30 is substantially cylindrical, and is connected to the second handle 20 with the door 1 sandwiched therebetween, and the first handle 10 is attached to it. In this embodiment, two screw holes 20a are formed in the second handle 20, and the base 30 is connected to the second handle 20 by two mounting screws 31. In addition, corresponding to the substantially cylindrical shape of the base 30, the first handle 10 has a substantially cylindrical hollow portion 11 into which the base 30 is inserted.

[0017] 5, at least one engagement protrusion 40 is formed on one of the first handle 10 and the base 30. In the embodiment, the at least one engagement protrusion 40 protrudes from a peripheral wall surface 11a of the hollow portion 11 in the first handle 10 into the hollow portion 11. More specifically, a pair of shaft holes 10a are drilled in the peripheral wall surface 11a at opposing positions sandwiching the axis of the hollow portion 11, and a pair of shaft members are inserted into the pair of shaft holes 10a so that their tips protrude by a predetermined length, whereby the two engagement protrusions 40 protrude from the peripheral wall surface 11a into the hollow portion 11.

[0018] 2 and 4, the engagement groove portion 50 is formed on the other of the first handle 10 and the base 30, and engages with at least one engagement protrusion 40 to lock the first handle 10 to the base 30. In the embodiment, the engagement groove portion 50 is formed so as to extend in the circumferential direction on the outer circumferential surface 30a of the base 30 so as to go substantially around the outer periphery of the base 30.

[0019] 4, on the outer peripheral surface 30a of the base 30, notches 51 corresponding to each engagement protrusion 40 are formed in the partition of the engagement groove portion 50. The notches 51 are passages for pressing the first handle 10 in the pushing direction X1 to push each engagement protrusion 40 into the engagement groove portion 50. In the embodiment, two notches 51 corresponding to the two engagement protrusions 40 are formed at opposing positions sandwiching the axis of the base 30 therebetween.

[0020] Furthermore, as shown in FIG. 4, a first stopper portion 50a and a second stopper portion 50b are formed on the outer peripheral surface 30a of the base 30 so as to make the engagement groove portion 50 discontinuous.

[0021] The first stopper portion 50a is disposed at a position rotated a predetermined angle in the locking direction X2 from one of the two cutout portions 51, for example, the lower left cutout portion 51 in Fig. 4(b). One of the two engagement protrusions 40, for example, the left engagement protrusion 40 in Fig. 5(b), is pushed into the engagement groove portion 50 through one of the two cutout portions 51, and the other of the two engagement protrusions 40 is pushed into the engagement groove portion 50 through the other of the two cutout portions 51. When the first handle 10 is rotated a predetermined angle in the locking direction X2 and one engagement protrusion 40 abuts against the first stopper portion 50a, the first handle 10 cannot rotate and is positioned at a predetermined locking position with respect to the base 30.

[0022] 4(b), the second stopper portion 50b is disposed at a position adjacent to the other of the two notches 51 in the direction opposite to the locking direction X2. After the two engagement protrusions 40 are pushed into the engagement groove portion 50 through the two notches 51, when an attempt is made to rotate the first handle 10 in the direction opposite to the locking direction X2, the other engagement protrusion 40 comes into contact with the second stopper portion 50b, and the rotation of the first handle 10 is prevented.

[0023] 2 and 3, the fixing means 60 fixes the relative positional relationship between the first handle 10 and the base 30 when the first handle 10 is engaged with the base 30. In this embodiment, the fixing means 60 includes a set screw 61, a base-side screw hole 62 provided in the base 30, and a handle-side screw hole 12 provided in the first handle 10. The base-side screw hole 62 and the handle-side screw hole 12 have the same diameter.

[0024] The set screw 61 screws into the base-side screw hole 62 and the handle-side screw hole 12, preventing rotation of the first handle 10 with respect to the base 30 and fixing the relative positional relationship between the first handle 10 and the base 30. The handle-side screw hole 12 has one end opening on the outer surface of the first handle 10 and the other end opening on the peripheral wall surface 11a of the hollow portion 11, and is formed so as to penetrate the peripheral wall of the hollow portion 11 in the first handle 10 from the outer surface of the first handle 10 to reach the hollow portion 11. The first handle 10 is attached to the base 30 so that the opening of the handle-side screw hole 12 on the outer surface of the first handle 10 faces downward.

[0025] The base screw hole 62 opens on the outer peripheral surface 30a of the base 30, and the base 30 is attached to the door 1 so that the opening of the base screw hole 62 on the outer peripheral surface 30a faces downward. The base screw hole 62 is formed at a position that is aligned in a straight line with the handle screw hole 12 when the first handle 10 is positioned at a predetermined locking position with respect to the base 30. In other words, when the first handle 10 is positioned at a predetermined locking position with respect to the base 30, the axis of the base screw hole 62 and the axis of the handle screw hole 12 coincide with each other, and the base screw hole 62 and the handle screw hole 12 form a single continuous screw hole.

[0026] The setscrew 61 has a hexagonal hole at its rear end, and is screwed into the handle-side screw hole 12 and the base-side screw hole 62 in that order from the outside of the first handle 10 using a tool such as a hexagonal wrench. The overall length of the setscrew 61 is set to a length that allows the entire setscrew 61 to be accommodated in the handle-side screw hole 12 and the base-side screw hole 62.

[0027] Next, an example of a process for attaching the door handle according to the embodiment to the door 1 will be described with reference to Figs. 2, 3 and 6.

[0028] Step 1: As shown in FIG. 2, the mounting screws 31 are inserted through the spring washer 32, the screw insertion hole 30b of the base 30, the through hole 33a of the rubber sheet 33, and the cylindrical protective rubber 34, and the spring washer 32, the base 30, the rubber sheet 33, and the protective rubber 34 are set on the two mounting screws 31.

[0029] Step 2: Place the two protective rubbers 34 inside the cutout hole 1a of the door 1, and with the base side screw hole 62 of the base 30 facing downward, insert the shank tips of the two mounting screws 31 into the cutout hole 1a of the door 1 from the pull side to the push side of the door 1.

[0030] Step 3: On the push side of the door 1, the mounting screws 31 are inserted into the through holes 35a of the rubber sheet 35, and the rubber sheet 35 is set on the two mounting screws 31. After that, the two mounting screws 31 are tightened into the two screw holes 20a of the second handle 20 to connect the second handle 20 and the base 30, and the second handle 20 and the base 30 are attached to the door 1.

[0031] Step 4: As shown in Fig. 6, the first handle 10 is pressed toward the door 1 so that the hollow portion 11 of the first handle 10 fits into the base 30 at an angle where the two notches 51 and the two engagement protrusions 40 match, and the two engagement protrusions 40 are pushed into the engagement grooves 50. When fitting the hollow portion 11 of the first handle 10 into the base 30, the orientation of the first handle 10 is determined so that the handle-side screw hole 12 faces downward when the first handle 10 is in the locking position.

[0032] Step 5: When the two engagement protrusions 40 reach the engagement groove 50, the first handle 10 is rotated in the direction shown by the outline arrow in Fig. 6 to the locking position, and the first handle 10 is locked to the base 30. Note that the direction shown by the outline arrow in the figure coincides with the locking direction X2.

[0033] Step 6: As shown in FIG. 3, the set screw 61 is tightened from the outside of the first handle 10 through the handle side screw hole 12 to the base side screw hole 62, thereby fixing the first handle 10 so that it does not rotate relative to the base 30, thereby fixing the relative positional relationship between the first handle 10 and the base 30.

[0034] As described above with reference to Figures 1 to 6, according to the door handle of the embodiment, the second handle 20 is connected to the base 30 with the door 1 sandwiched therebetween, and the first handle 10 is engaged with the base 30 by engagement between at least one engagement protrusion 40 and the engagement groove portion 50, and when the first handle 10 is engaged with the base 30, the fixing means 60 fixes the relative positional relationship between the first handle 10 and the base 30.

[0035] Therefore, in the installation process of the door handle of the embodiment, first, the second handle 20 is attached to the door 1 by connecting the second handle 20 and the base 30, and then the first handle 10 is engaged with the base 30 by engaging at least one engagement protrusion 40 with the engagement groove portion 50, and with the first handle 10 engaged with the base 30, the relative positional relationship between the first handle 10 and the base 30 is fixed by a fixing means. This procedure allows the door handle to be installed, and there is no need to perform tasks such as aligning the locking screws while holding the two handles on both the inside and outside of the door 1 and tightening the locking screws until installation of the door handle is completed, so even a single worker can easily install the two handles to be placed on both sides of the door.

[0036] 1 to 6, in the door handle according to the embodiment, the base 30 is substantially cylindrical, the first handle 10 has a substantially cylindrical hollow portion 11 into which the base 30 is inserted, the engagement groove portion 50 is formed on the outer peripheral surface 30a of the base 30 so as to extend in the circumferential direction, and at least one engagement protrusion 40 protrudes into the hollow portion 11 from the peripheral wall surface 11a of the hollow portion 11 in the first handle 10. Therefore, the first handle 10 can be locked to the base 30 by a simple operation of inserting the base 30 into the hollow portion 11 and rotating the first handle 10, and even a single worker can more easily install two handles to be disposed on both sides of the door.

[0037] 1 to 6, in the door handle according to the embodiment, the fixing means 60 includes the handle-side screw hole 12, the base-side screw hole 62, and the set screw 61. Therefore, the relative positional relationship between the first handle 10 and the base 30 can be fixed by a simple operation of simply screwing the set screw 61 into the handle-side screw hole 12 and the base-side screw hole 62. In addition, for example, by forming the handle-side screw hole 12 and the base-side screw hole 62 so that they match at a position where the first handle 10 is positioned by the first stopper portion 50a, the handle-side screw hole 12 and the base-side screw hole 62 can be easily aligned, and the relative positional relationship between the first handle 10 and the base 30 can be fixed by a further simple operation.

[0038] 1 to 6, in the door handle according to the embodiment, the door 1 is a hinged door, the first handle 10 is disposed on the pull side of the door 1, the second handle 20 is disposed on the push side of the door 1, and a first height L1 of the first handle 10 from the door 1 is made higher than a second height L2 of the second handle 20 from the door 1. Therefore, the first handle 10 on the pull side, which is less likely to require force when opening the door 1, can be easier to grasp than the second handle 20 on the push side, making it easy to open and close the door 1.

[0039] Next, another embodiment of the present invention will be described with reference to Fig. 7 to Fig. 9. Fig. 7 is an overall perspective view showing a door handle according to another embodiment of the present invention. Fig. 8 is a side view showing the door handle of Fig. 7. Fig. 9(a) is a front view showing details of a first handle according to another embodiment. Fig. 9(b) is a cross-sectional view taken along arrow BB in Fig. 9(a).

[0040] As shown in Figures 7 to 9, the door handle of this embodiment differs from the door handle of Figures 1 to 6 in that the outer shapes of the first handle 10A and the second handle 20A are truncated cones. Other than the outer shapes of the first handle 10A and the second handle 20A, the door handle of this embodiment is similar to the door handle of Figures 1 to 6.

[0041] The outer shapes of the first handle 10A and the second handle 20A are truncated cones, which differs from the door handles in Figures 1 to 6. This allows the shape of the handle to be selected according to the design of the door 1 and the environment in which the door 1 is installed, thereby meeting a variety of needs.

[0042] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 9). However, the present invention is not limited to the above-described embodiments, and can be embodied in various forms without departing from the spirit and scope of the present invention.
