[Modes for carrying out the invention]

[0008] Figure 1 is a perspective view of the first handle device 10a and the second handle device 10b of the embodiment. The first handle device 10a and the second handle device 10b (if not distinguished, referred to as "handle device 10") are fixed to the door 12 with the door 12 in between.

[0009] The first handle device 10a, when pulled by the user, moves backward, i.e., away from the door 12, and unlocks. The second handle device 10b, when pushed by the user, moves forward, i.e., towards the door 12, and unlocks. The directions of approaching the door 12 and away from the door 12 are sometimes referred to as the forward and backward directions.

[0010] The handle device 10 comprises at least a back plate portion 14, a case portion 16, and a fixing pin 18. The first handle device 10a and the second handle device 10b each have a pair of back plate portions 14 and case portions 16 that are fixed to the door 12. The back plate portion 14 is fixed to the door 12. The case portion 16 houses at least a part of the back plate portion 14 and is fixed to the back plate portion 14.

[0011] The handle portion 20 is connected to the case portion 16 via internal components (not shown) housed in the case portion 16. The case portion 16 houses internal components such as a locking portion for locking the door 12 in the closed position, a spring that biases the locking portion in the closing direction, a shaft that rotatably supports the locking portion, and a bracket that supports the shaft.

[0012] Figure 2 is a perspective view of the handle device 10 as seen from the back. Figure 2 shows the upper part of the handle device 10. The case portion 16 has an opening 16a on the back side. The handle portion 20 has a recess 20a that accommodates the front edge of the case portion 16.

[0013] The back plate portion 14 is at least partially accommodated in the case portion 16 from the opening 16a. A pair of fixing screws 22 protrude from the back plate portion 14. The fixing screws 22 are fastened to the fixing pins 18. Note that the fixing screws 22 may be directly fastened to the door 12. An insertion hole portion 24 is formed in the center of the back plate portion 14. A lock portion (not shown) accommodated in the case portion 16 is inserted through the insertion hole portion 24, locks the door 12 in the closed state, and is unlocked by the forward and backward operation of the handle portion 20.

[0014] FIG. 3 is a perspective view of the back plate portion 14 as viewed from the back side. FIG. 4 is a perspective view of the back plate portion 14 as viewed from the front side. The back plate portion 14 has a main body plate portion 26, an upper surface portion 28, a lower surface portion 30, and side surface portions 32.

[0015] The main body plate portion 26 is formed in a rectangular flat plate shape and covers the opening 16a. The main body plate portion 26 has a first insertion hole 34 and a second insertion hole 36 for inserting the fixing screws 22. The main body plate portion 26 has an upper side 26a, a lower side 26b, and a pair of side sides 26c.

[0016] The upper surface portion 28 bends from the upper side 26a of the main body plate portion 26 and stands up with respect to the main body plate portion 26. The lower surface portion 30 bends from the lower side 26b and stands up with respect to the main body plate portion 26. The pair of side surface portions 32 bend from the side sides 26c and stand up with respect to the main body plate portion 26. The upper surface portion 28, the lower surface portion 30, and the side surface portions 32 stand up toward the handle portion 20 side and are accommodated in the case portion 16.

[0017] The first fixing portion 28a is formed to penetrate the upper surface portion 28 in a hole shape. The lower surface portion 30 has a pair of concave portions 30a. The concave portions 30a are recessed upward. The second fixing portion 32a is formed in a hook shape.

[0018] FIG. 5 is a perspective view of the case portion 16 as viewed from the back side. FIG. 6(a) is a rear view of the case portion 16, and FIG. 6(b) is a cross-sectional view taken along line A-A of the case portion 16 shown in FIG. 6(a).

[0019] The case portion 16 has an upper wall portion 40, a lower wall portion 42, a side wall portion 44, a connecting plate portion 46, a first fixed portion 48, a suspension portion 50, a slit 52, a connecting hole portion 54, an upper insertion opening 55, a lower insertion opening 56, a lateral insertion opening 58, a second fixed portion 60, and a screw hole portion 62.

[0020] The upper wall portion 40 and the lower wall portion 42 are arranged opposite each other. A pair of side wall portions 44 are arranged opposite each other and are connected to the upper wall portion 40 and the lower wall portion 42. As a result, the case portion 16 is formed in a rectangular tubular shape.

[0021] The connecting plate portion 46 is formed extending from one side wall portion 44 to the other side wall portion 44 and is formed to cover the lower half of the opening 16a. The connecting plate portion 46 has a plurality of connecting holes 54 into which screws for connecting the case portion 16 to the handle portion 20 are inserted. Screws are inserted into the connecting holes 54 from the back side of the case portion 16. A slit 52 is formed by cutting out downward from the upper end of the connecting plate portion 46. A locking portion that displaces up and down in accordance with the front-rear movement of the handle portion 20 is inserted through the slit 52. The suspension portion 50 is formed extending from one side wall portion 44 to the other side wall portion 44 and is located above and further away from the connecting plate portion 46.

[0022] The first fixed portion 48 is formed convexly on the inner surface of the upper wall portion 40 and protrudes downward. The first fixed portion 48 is located at the upper insertion opening 55. The upper insertion opening 55 is formed on the inside of the upper wall portion 40 along the upper wall portion 40 and allows the upper surface portion 28 of the back plate portion 14 to be inserted.

[0023] The lower insertion opening 56 is formed on the inside of the lower wall portion 42 and along the lower wall portion 42, and the lower surface portion 30 of the backing plate portion 14 can be inserted into it. The lateral insertion opening 58 is formed on the inside of the side wall portion 44 and along the side wall portion 44, and the second fixing portion 32a of the backing plate portion 14 can be inserted into it.

[0024] The second fixed portion 60 is adjacent to the lateral insertion opening 58, protrudes from the inner surface of the side wall portion 44, and has a step for hooking the second fixed portion 32a. The screw hole portion 62 is formed through the lower wall portion 42 and has a screw groove.

[0025] Figure 7 is a cross-sectional view of the handle device 10 cut in the vertical direction. The handle portion 20 has a recessed portion 20a and a screw hole portion 20b. The outer edge of the case portion 16 fits into the recessed portion 20a. The screw hole portion 20b is formed for fastening the locking mechanism together with the fastened component 72. The fastened component 72 serves as a base when fastening the locking mechanism to the handle portion 20.

[0026] The upper portion 28 is inserted into and housed in the upper insertion opening 55. The first fixed portion 48 is inserted into the first fixed portion 28a and fixed in the front-rear direction. The first fixed portion 28a and the first fixed portion 48 constitute one of the fixing structures for the back plate portion 14 and the case portion 16. The fixing structure consisting of the first fixed portion 28a and the first fixed portion 48 forms a fixed state that fixes the back plate portion 14 and the case portion 16 in the front-rear direction.

[0027] The lower portion 30 is inserted into and housed in the lower insertion opening 56. The screw 70 is in contact with the lower portion 30, restricting movement that would release the fixed state of the back plate portion 14 and the case portion 16. By forming the screw hole portion 62 in the lower wall portion 42, the exposure of the screw hole portion 62 is reduced compared to when the screw hole portion 62 is formed in the side wall portion 44, thereby improving the design. The upper insertion opening 55 and the lower insertion opening 56 are greater than the plate thickness of the upper portion 28 and the lower portion 30, and greater than the protruding height of the first fixed portion 48. Therefore, the back plate portion 14 can move vertically when the upper portion 28 and the lower portion 30 are housed in the case portion 16.

[0028] Although the first fixing portion 28a is shown as being formed in a hole shape and the first fixed portion 48 is formed in a convex shape, the invention is not limited to this embodiment. For example, the first fixing portion 28a may be formed in a convex shape and the first fixed portion 48 may be formed in a hole shape. By forming the first fixed portion 48 in a convex shape, sufficient hooking space can be secured even if the thickness of the upper wall portion 40 is thinner compared to the case where it is formed in a hole shape.

[0029] Figure 8 is a cross-sectional view of the handle device 10 at a position passing through the screw hole 62. The recess 30a is recessed in the direction of insertion of the screw 70. The screw 70 is screwed into the screw hole 62 from below, and the tip of the screw 70 enters the recess 30a and contacts the lower surface 30.

[0030] The screw 70 pushes the lower surface 30 from below upward, causing the upper surface 28 to press against the upper wall 40. This prevents the back plate 14 from rattling relative to the case 16. The first fixing part 28a is restricted from moving away from the first fixed part 48, i.e., from moving downward, by the screw 70. The recess 30a receives the screw 70, which prevents the screw 70 from tilting.

[0031] Figure 9 is a cross-sectional view of the handle device 10 at a position passing through the second fixed portion 60. The side portion 32 is housed in the case portion 16, and the second fixing portion 32a is inserted into the lateral insertion opening 58. The second fixing portion 32a is hooked onto the second fixed portion 60 located above it. The second fixing portion 32a and the second fixed portion 60 constitute one of the fixing structures for the back plate portion 14 and the case portion 16. The fixing structure consisting of the second fixing portion 32a and the second fixed portion 60 forms a fixed state that fixes the back plate portion 14 and the case portion 16 in the front-rear direction.

[0032] Because the screw 70 is in contact with the lower surface portion 30, the movement of the second fixing portion 32a away from the second fixed portion 60 is restricted. In other words, the movement of the back plate portion 14 and the case portion 16 from a fixed state to an unlocked state is restricted by the screw that is screwed into the screw hole portion 62.

[0033] The second fixing portion 32a is formed on each of the pair of side wall portions 44. The second fixed portion 60 is formed on each of the side wall portions 44. This restricts the lateral movement of the back plate portion 14 and the case portion 16. Even if the handle portion 20 is pulled from the right or left side, rattling of the back plate portion 14 and the case portion 16 can be suppressed.

[0034] Figure 10 is a diagram illustrating the assembly method of the handle device 10. It is connected to the handle part 20 together with the case part 16 and internal components. The back plate part 14 is fixed to the door 12 by fixing pins 18 and fixing screws 22.

[0035] With the case section 16 attached to the handle section 20 and the back plate section 14 attached to the door 12, the worker grasps the case section 16 and performs the step of fixing it to the back plate section 14. The worker inserts the top section 28 into the upper insertion opening 55, the bottom section 30 into the lower insertion opening 56, and the second fixing section 32a into the side insertion opening 58.

[0036] As the case portion 16 sinks under its own weight, the first fixed portion 48 enters the first fixed portion 28a, and the second fixed portion 32a catches on the second fixed portion 60. The fixing structure can be switched from a release state, which releases the fixing of the back plate portion 14 and the case portion 16 in the front-to-back direction, to a fixed state.

[0037] Figure 11 is a front view of a gate equipped with a handle device 10. The gate comprises a handle device 10, a door 12, columns 74, a hinge-end blocking member 76, and a lock 78. The pair of columns 74 are erected in the ground. The door 12 is rotatably supported by the columns 74 and, in the closed state shown in Figure 11, closes the space between the pair of columns 74.

[0038] The hinge-blocking member 76 is provided between the column 74 and the door 12 and covers the hinge structure such as the hinge. The locking mechanism 78 has a locking part provided on one door 12, a locking hole provided on the other door 12, and a mechanism for moving the locking part in and out of the locking hole. The locking mechanism 78 is optional. The handle device 10 is fixed to each of the pair of doors 12. The user can rotate the door 12 by grasping and pulling or pushing the handle device 10.

[0039] Although Figure 11 shows a configuration in which a pair of doors 12 are provided, the configuration is not limited to this, and the doors 12 may be provided on only one of the pair of pillars 74. In any case, when closed, the doors 12 block the space between the pair of pillars 74.

[0040] The worker screws the screw 70 into the screw hole 62 from below. This causes the screw 70 to hit the lower surface 30, restricting the movement of the first fixed part 48 from coming off the first fixed part 28a.

[0041] The embodiments of this disclosure have been described in detail above. The embodiments described above are merely examples of how to implement this disclosure. The embodiments do not limit the technical scope of this disclosure, and many modifications are possible without departing from the spirit of the invention as defined in the claims.

[0042] In the embodiment, the handle device 10 is shown to have a pair of back plate portion 14 and case portion 16, but it is not limited to this embodiment. For example, one back plate portion 14 and one case portion 16 may be provided for the handle portion 20.

[0043] In the embodiment, a configuration is shown in which a first fixed portion 48 is formed in the upper wall portion 40 and a screw hole portion 62 is formed in the lower wall portion 42, but the embodiment is not limited to this configuration. For example, the screw hole portion 62 may be formed in the upper wall portion 40 and the first fixed portion 48 may be formed in the lower wall portion 42. In this configuration, a hole-shaped first fixing portion is formed in the lower surface portion 30. Depending on the mounting position of the case portion 16 to the door 12 and the inclination angle of the upper wall portion 40, the screw hole portion provided in the upper wall portion 40 can be made less conspicuous, thereby improving the design.

[0044] In the embodiment, the case portion 16 is shown to be connected to the handle portion 20 via a locking mechanism or the like, but the embodiment is not limited to this. For example, the case portion 16 may be directly connected to the handle portion 20.

[0045] In the embodiment, the first handle device 10a and the second handle device 10b are shown to be fixed to the door 12 by being connected to each other by a fixing pin 18, but the embodiment is not limited to this. For example, the back plate portion 14 of the handle device 10 may be directly fixed to the door 12 by fixing screws 22.

[0046] In the embodiment, the fixing structure is shown to have a first fixing part 28a and a first fixed part 48, and a second fixing part 32a and a second fixed part 60, but it is not limited to this embodiment. For example, the fixing structure may have either the first fixing part 28a and the first fixed part 48, or the second fixing part 32a and the second fixed part 60.

[0047] In the embodiment, the fixing structure is shown to be switched between a fixed state and an unlocked state by relative vertical movement of the back plate portion 14 and the case portion 16, but the embodiment is not limited to this. For example, the fixed state and the unlocked state may be switched by relative horizontal movement of the back plate portion 14 and the case portion 16. In this case, the first fixing portion 28a is formed on the side portion 32, and the first fixed portion 48 is formed on the side wall portion 44.

[0048] In yet another embodiment of the fixing structure, the first fixing part and the first fixed part may engage when the case part 16 is moved so as to be pushed toward the front back plate part 14. For example, the first fixing part and the first fixed part may be configured by a snap-fit ​​structure and engage by hooking the claws. [Explanation of Symbols]
