Description

[Technical field]

[0001] The present invention relates to a technique for a handle device provided on structures such as inspection hatches, switchboards, distribution boards, and control panels. [Background technology]

[0002] Conventionally, a handle device provided in a structure such as an inspection hatch, a distribution board, a switchboard, or a control board is known as shown in Patent Document 1. The handle device of Patent Document 1 includes a handle base fixed to the front of a door of a structure such as an inspection hatch or a distribution board, a handle attached to a handle shaft rotatably inserted into the handle base so as to be able to rise and fall relative to the handle base, and a fastener attached rotatably via the handle shaft to the rear side of the handle base and capable of engaging and disengaging with a receiving metal fitting on a fixed frame body side such as a box body by operating the handle. In the handle device of Patent Document 1, when the door is opened or closed, the handle is raised from the handle base and rotated to release the engagement of the fastener with the receiving metal fitting. After the door is closed, the handle is collapsed onto the handle base and stored. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-234651 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the handle device of Patent Document 1, the handle is stored on the handle base after the door is closed, but since the handle and the handle base are fixed to the front surface of the door, the design appearance of the door is impaired. In addition, since the handle is provided on the front surface of the door, the handle is easily visible when not being operated, and therefore the door can be easily opened and closed by operating the handle. In particular, in structures that store equipment, such as inspection hatches or switchboards, it is not desirable for people other than the workers who inspect or handle the equipment to easily open and close the door, so there is a demand for a handle device that places the handle in a position that is not easily visible when not being operated.

[0005] SUMMARY OF THE PRESENT INVETION The present invention is devised to solve the above-mentioned problems, and has an object to provide a handle device that makes the handle less noticeable when not being operated, without compromising the aesthetic appearance of the door. [Means for solving the problem]

[0006] In order to solve the above problems, the handle device of the present invention is a handle device that is installed in a structure having a frame provided on an edge of an opening, and a door provided inside the frame for opening and closing the opening, the handle being disposed in a gap between the frame and an edge side of the door and installed to be able to swing freely on the edge side of the door, a pivot shaft that is installed on the edge side of the door and rotates by operating the handle, a stopper that is installed on the edge side of the door and swings by rotation of the pivot shaft, and a receiver that is installed on the frame and engages with the stopper when the handle is not operated, the handle has a protrusion that is formed to protrude from the gap to a front surface of the door when the handle is not operated, and when the protrusion is operated, the swing tip side of the handle swings around the pivot shaft to protrude from the gap to the front surface of the door, and when the swing tip side of the handle protruding from the front surface of the door is operated to rotate the pivot shaft, the stopper is released from engagement with the receiver.

[0007] In the above configuration, by pressing the protruding portion protruding from the gap, the swing tip of the handle, which is disposed in the gap when the handle is not being operated, protrudes from the gap. Furthermore, by operating the swing tip of the handle protruding from the gap, the engagement between the stop metal and the receiving metal is released, and the door is unlocked.

[0008] In the handle device of the present invention, the pivot shaft is made rotatable by manipulating the swing tip side of the handle that protrudes from the gap toward the front surface of the door and engaging the swing base end side of the handle with the pivot shaft.

[0009] In the above configuration, the pivot tip side of the handle protruding from the gap is operated and the pivot base end side of the handle is engaged with the rotary shaft, thereby enabling the rotary shaft to be rotated by operating the handle.

[0010] The handle device of the present invention has a biasing member that biases the rotation shaft in a direction in which the fastening metal fitting engages with the receiving metal fitting when the handle is not being operated.

[0011] In the above-described configuration, the rotating shaft rotates due to the biasing force of the biasing member, and the fastening metal fitting swings in the direction in which it engages with the receiving metal fitting.

[0012] In the handle device of the present invention, the position at which the fastening metal fitting and the receiving metal fitting engage is formed on the same horizontal plane as the axis of the rotating shaft.

[0013] In the above-described configuration, the stop metal fitting and the receiving metal fitting engage with each other at a position where there is no misalignment in the height direction with the axis of the rotating shaft. Effect of the Invention

[0014] According to the handle device of the present invention, when the handle is not operated, only the protrusion of the handle protrudes from the gap between the frame and the door end side toward the front surface of the door, and when the handle is operated, the protrusion is operated so that the swing tip side of the handle, which is located in the gap when the handle is not operated, protrudes from the gap and the door can be unlocked, so that the door can be locked and unlocked reliably while the handle can be hidden in a place where it is not easily seen by others when the handle is not operated. Also, because the handle is located in the gap and not on the front surface of the door, the appearance of the door design can be improved. [Brief description of the drawings]

[0016] A handle device 10 according to the present invention will be described. As shown in Fig. 1 and Fig. 2, the handle device 10 is used, for example, in an inspection hatch 90 (an example of a "structure") provided in a wall surface, and is a device for opening and closing a door 92 of the inspection hatch 90, as well as locking and unlocking the door 92. The inspection hatch 90 in which the handle device 10 is used is mainly composed of a frame 91 provided on the edge of the opening that forms the inspection hatch 90, and a door 92 provided inside the frame 91 for opening and closing the opening.

[0017] As shown in Fig. 1 to Fig. 3, the handle device 10 is mainly composed of a lock case 11 which is the device main body, a handle 12 for opening and closing a door 92, a rotating shaft 13 which rotates by operating the handle 12, and a stop metal fitting 14 and a receiving metal fitting 15 for locking and unlocking the door 92. In the handle device 10, by operating the handle 12 arranged in a gap 93 between a frame 91 and a door end side 92A of the door 92, the stop metal fitting 14 swings via the rotating shaft 13 held in the lock case 11, and the stop metal fitting 14 and the receiving metal fitting 15 are disengaged to unlock the door 92. In the handle device 10, by releasing the operation of the handle 12 to close the door 92, the stop metal fitting 14 and the receiving metal fitting 15 are engaged with each other, and the door 92 is automatically locked.

[0018] 1 and 3, the lock case 11 is formed in a box shape and is fixed to an inner surface 92a of a door end side 92A of a door 92 by a first fastening member 16. The lock case 11 rotatably holds a rotation shaft 13 therein.

[0019] The handle 12 is a long plate material, and is rotatably attached to the pivot shaft 13 via the second fastening member 17 so as to face the outer surface 92b of the door end side 92A of the door 92. The handle 12 has an elongated hole 12a formed on one end side (swing tip side 12A) thereof. The elongated hole 12a is a hole through which the user's finger can be inserted when the user operates the handle 12.

[0020] As shown in Figs. 1 to 3, the handle 12 has a mounting hole 12b and a protrusion 12c formed on the other end side (swing base end side 12B). The mounting hole 12b is a hole for mounting the handle 12 to the rotating shaft 13. As shown in Fig. 5, the mounting hole 12b is formed as an elongated hole inclined at a predetermined angle θ with respect to the longitudinal axis S1 of the handle 12. As shown in Figs. 3 and 5, the mounting hole 12b has a pair of protrusions 12d protruding from the edge of the elongated hole to the center. The rotating shaft 13 is inserted into the mounting hole 12b and the protrusions 12d engage with the rotating shaft 13, whereby the handle 12 is locked to the rotating shaft 13.

[0021] 1 to 3, the protrusion 12c is a substantially semicircular protrusion formed to protrude from one end of the swing base end side 12B of the handle 12. The protrusion 12c is formed to protrude forward from a gap 93 between the frame 91 and a door end side 92A of the door 92 toward a front surface 92c of the door 92 when the handle 12 is not being operated.

[0022] The rotating shaft 13 has both ends held by a lock case 11 provided on the inner surface 92a of the door end side 92A of the door 92. The handle 12 is attached to one end of the rotating shaft 13 by a second fastening member 17 so as to be able to swing, and a fastener 14 is fixed to the other end by a third fastening member 18. As shown in Figs. 3 and 5, the rotating shaft 13 has one end that holds the handle 12 formed in an elongated elliptical shape that can be inserted into the mounting hole 12b of the handle 12, and a flat surface portion 13a that can be engaged with the protrusion 12d of the handle 12 is formed on the periphery of the elongated elliptical shape. The rotating shaft 13 rotates when the flat surface portion 13a engages with the protrusion 12d of the handle 12 by operating the handle 12.

[0023] A biasing member 19 is attached to the rotating shaft 13 for biasing the rotating shaft 13 in a direction in which the fastening metal fitting 14 engages with the receiving metal fitting 15. The biasing member 19 is made of a coil spring and is wound around the periphery of the rotating shaft 13. Since the rotating shaft 13 is biased by the biasing member 19 in a direction in which the fastening metal fitting 14 engages with the receiving metal fitting 15, even if the rotating shaft 13 is rotated to a predetermined position by operating the handle 12, the biasing force of the biasing member 19 automatically rotates the rotating shaft 13 in the opposite direction to a position in which the fastening metal fitting 14 engages with the receiving metal fitting 15. As shown in FIG. 4, the rotating shaft 13 is provided with a protrusion 21, and the protrusion 21 of the rotating shaft 13, which rotates due to the biasing force of the biasing member 19, abuts against the inner wall of the lock case 11, thereby controlling the rotation angle of the rotating shaft 13.

[0024] The stop fitting 14 has its swing base end 14B fixed to the end of the rotating shaft 13 provided on the door leading side 92A of the door 92, and its swing tip end 14A is a plate material bent into a hook shape, and swings when the rotating shaft 13 rotates. The hook-shaped portion (swing tip 14a) of the swing tip end 14A of the stop fitting 14 engages with the receiving fitting 15. Since the rotating shaft 13 is biased by the biasing member 19 in the direction in which the stop fitting 14 engages with the receiving fitting 15, the stop fitting 14 is held in a position where it can engage with the receiving fitting 15 when the handle 12 is not operated.

[0025] 1, the receiving metal fitting 15 is a plate material bent into an L-shape in plan view that is fixed to the inner surface 91a of the frame 91 by the fourth fastening member 20, and engages with the fastener 14 when the handle 12 is not being operated. The receiving metal fitting 15 has a protruding portion 15a that protrudes from the inner surface 91a of the frame 91, and engages with the fastener 14 at the protruding portion 15a.

[0026] 4, in the handle device 10, the pivoting tip side 14A of the fastening metal 14 bent into a hook shape engages with the protruding portion 15a of the receiving metal 15 so as to wrap around the protruding portion 15a of the receiving metal 15 from below, so that the position P where the pivoting tip 14a of the fastening metal 14 and the protruding portion 15a of the receiving metal 15 engage is formed on the same plane as the horizontal plane M including the axis S2 of the rotating shaft 13. That is, in the handle device 10, the engagement position P between the fastening metal 14 and the receiving metal 15 is on the same horizontal line as the axis S2 of the rotating shaft 13 in a side view, and the fastening metal 14 and the receiving metal 15 engage at a position where there is no misalignment in the height direction with the axis S2 of the rotating shaft 13. By engaging the fastener 14 and the receiving bracket 15 in such a position, it is possible to prevent the fastener 14 from coming off the receiving bracket 15 and swinging when back pressure (pressure applied in the direction that tries to open the door 92 due to wind entering through the gap 93 of the inspection hatch 90) is applied to the door 92.

[0027] Next, a description will be given of the operation of the handle device 10. As shown in Fig. 2, when the door 92 is closed (when the handle 12 is not operated), the protrusion 12c of the handle 12 protrudes forward from the gap 93 toward the front surface 92c of the door 92. Therefore, when the door 92 is closed, the user can visually recognize the protrusion 12c of the handle 12.

[0028] 1 and 7, when a user pushes up the lower part of the protruding portion 12c of the handle 12 toward the gap 93, the swing tip side 12A of the handle 12 swings around the rotation shaft 13. This causes the swing tip side 12A of the handle 12 to protrude from the gap 93 toward the front surface 92c of the door 92, allowing the user to hold the swing tip side 12A of the handle 12 and operate it.

[0029] 6, when the user lifts the swing tip side 12A of the handle 12 up to a predetermined angle θ with respect to the vertical direction, the protrusion 12d of the handle 12 engages with the flat surface 13a at the peripheral end of the rotating shaft 13, and the rotating shaft 13 becomes rotatable by operating the handle 12. There is a predetermined play between the mounting hole 12b of the handle 12 and the peripheral end of the rotating shaft 13 (the joint between the handle 12 and the rotating shaft 13), and by operating the swing tip side 12A of the handle 12 to a position where it is at the predetermined angle θ with respect to the vertical direction, the protrusion 12d of the handle 12 engages with the flat surface 13a at the peripheral end of the rotating shaft 13, and the rotating shaft 13 becomes rotatable by operating the handle 12.

[0030] 8, when the rotating shaft 13 is rotated by operating the handle 12, the stop metal fitting 14 swings due to the rotation of the rotating shaft 13. As a result, the swing tip 14a of the stop metal fitting 14 and the protruding portion 15a of the receiving metal fitting 15 are disengaged from each other, and the door 92 is unlocked.

[0031] On the other hand, when the user releases the swing tip side 12A of the handle 12 to release the operation of the handle 12, the rotating shaft 13 rotates in the opposite direction to the operation of the handle 12 due to the biasing force of the biasing member 19. When the rotating shaft 13 rotates due to the biasing force of the biasing member 19, the stop metal fitting 14 swings in the opposite direction to the operation of the handle 12. At this time, if the door 92 is closed, the swing tip 14a of the stop metal fitting 14 engages with the protruding portion 15a of the receiving metal fitting 15 to lock the door 92. Also, if the door 92 is open, the swing tip 14a of the stop metal fitting 14 is in a raised state without engaging with the protruding portion 15a of the receiving metal fitting 15, but as shown in FIG. 9, when the user moves the door 92 in the closing direction, the inclined portion 14b of the swing tip side 14A of the stop metal fitting 14 abuts against the lower portion of the protruding portion 15a of the receiving metal fitting 15 and is pushed downward. Furthermore, when the user moves the door 92 in the closing direction, the inclined portion 14b of the fastening metal 14 moves away from the lower portion of the protruding portion 15a of the receiving metal 15. Then, the swinging tip side 14A of the fastening metal 14 is flipped up by the biasing force of the biasing member 19, so that the swinging tip 14a of the fastening metal 14 engages with the protruding portion 15a of the receiving metal 15, and the door 92 is locked. In this way, in the handle device 10, when the user closes the door 92, the swinging tip 14a of the fastening metal 14 engages with the protruding portion 15a of the receiving metal 15, and the door 92 is automatically locked.

[0032] As described above, in the handle device 10, when the handle 12 is not operated, only the protrusion 12c of the handle 12 protrudes from the gap 93 between the frame 91 and the door end side 92A of the door 92 to the front surface 92c of the door 92, and when the handle 12 is operated, the protrusion 12c is operated to cause the swing tip side 12A of the handle 12, which is disposed in the gap 93 when the handle 12 is not operated, to protrude from the gap 93, thereby enabling the door 92 to be unlocked. This allows the door 92 to be locked and unlocked reliably, while allowing the handle 12 to be hidden in a place that is less visible to the naked eye when the handle 12 is not operated. In addition, since the handle 12 is disposed in the gap 93, not on the front surface 92c of the door 92, the design appearance of the door 92 can be improved.

[0033] In this embodiment, the protrusion 12c of the handle 12 is formed on the swing base end side 12B of the handle 12, but this is not limited thereto, and the protrusion 12c may be formed on the swing tip side 12A of the handle 12. In this case, the protrusion 12c is pulled outward from the gap 93 (to the opposite side of the gap 93), so that the swing tip side 12A of the handle 12 swings around the rotation shaft 13 and protrudes from the gap 93 toward the front surface 92c of the door 92.

[0034] In this embodiment, the structure in which the handle device 10 is provided is an inspection hatch 90, but this is not limited to this and the handle device 10 may be provided in a structure such as a switchboard, distribution board, control panel, etc.

[0035] In this embodiment, the handle device 10 is described for a case in which the door 92 is right-handed, but by rearranging the positions of the handle 12 and the fastener 14, the handle device 10 can also be used when the door 92 is left-handed. [Explanation of symbols]
