DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] In Figures 1 and 2, the imaginary lines indicate a door frame W and a door panel T, such as a sliding door, that opens and closes within the door frame W. A hook lock device 1 is embedded within the door panel T, and a latch 18 is provided on the door frame W to engage with the hook member 5 of the hook lock device 1.

[0014] The door panel T has a through hole Ta that penetrates the inner and outer surfaces, and a storage hole Tb that connects this through hole Ta to the front surface of the door panel T. The main body case 3 of the hook lock device 1 is inserted into the storage hole Tb from the front surface of the door panel T, and its rear reaches the through hole Ta.

[0015] 1 to 7, the hook lock device 1 comprises a main body case 3, a sickle member 5 housed within the main body case 3, an operating shaft 6 that penetrates the main body case 3, a linkage mechanism 7 that converts the rotation of the operating shaft 6 into the movement of the sickle member 5, with the tip of the sickle extending and retracting from the main body case 3, a knob seat 8 and an outlet seat 9 attached to the inside and outside surfaces of the door panel T, a knob 12 fixed to one end of the operating shaft 6 within the knob seat 8, and an unlocking indicator member 13 fixed to the other end of the operating shaft 6 within the outlet seat 9.

[0016] The main body case 3 is made up of two roughly rectangular box bodies 3a joined together to form a space for storing the sickle member 5 inside, and a mounting plate 3b is fixed to the front part, and this mounting plate 3b is attached to the door panel T by screwing it to the front surface of the door panel T. A sickle guide groove 3c is formed on the inner surface of the two-part box body 3a.

[0017] The sickle member 5 is made of two steel plates bonded together, and has a straight section 5a and a sickle-shaped sickle tip 5b formed by bending the tip of the straight section 5a into a roughly L-shape. Two sliding pins 5c, one at the front and one at the back, are provided on the straight section 5a, and both ends of these two sliding pins 5c are slidably inserted into sickle guide grooves 3c on the inner surface of the two-part box body 3a, setting the posture during forward and backward movement.

[0018] The operating shaft 6 is a rectangular shaft with a square cross section, passes through the main body case 3, and is disposed approximately concentrically with the through-hole Ta, with the base of a swing link 20 fitted and attached inside the main body case 3. The tip side of this swing link 20 is fitted into a sliding pin 5c on the rear side of the sickle member 5, and the swing link 20 swings as the operating shaft 6 turns, allowing the sickle member 5 to move back and forth.

[0019] A protrusion 20a is formed on the outer periphery of the base side of the swing link 20, and is in contact with a leaf spring 21 arranged above the protrusion 20a. The swing link 20 swings from a retracted position shown by the imaginary line in Fig. 3 to an advanced position shown by the solid line, and each position can be set and maintained by the protrusion 20a abutting against the leaf spring 21. When the swing link 20 rotates, it elastically deforms the leaf spring 21, and its elastic restoring force causes it to switch unstable so as not to stop at an intermediate position, and it is positioned at either the retracted position or the advanced position.

[0020] The sickle guide groove 3c, sliding pin 5c, swing link 20, leaf spring 21, etc. constitute an interlocking mechanism 7 that converts the rotation of the operating shaft 6 into the movement of the sickle member 5, in which the sickle tip 5b moves in and out of the main body case 3.

[0021] The front straight portion of the sickle guide groove 3c is inclined upward, and when the front sliding pin 5c enters this inclined portion, the sickle member 5 advances and the sickle tip 5b moves upward. As the sickle tip 5b moves upward, the sickle member 5 wraps around the back of the latch 18 of the door frame W and latches.

[0022] In addition, the hook lock device 1 may be arranged upside down, and the hook tip 5b may move downward as the hook member 5 advances, thereby engaging with the back of the latch 18 of the door frame W.

[0023] The knob seat 8 forms the edge of one end of the through hole Ta and has a cylindrical portion 8a that fits inside the inner circumference of one end of the through hole Ta, a flange portion 8b that extends radially outward from one end of this cylindrical portion 8a and abuts against the side (inner and outer side) of the door panel T, and a closing portion 8c that extends radially inward from the other end of the cylindrical portion 8a and closes the through hole Ta, with the upper part of this closing portion 8c being cut out to form an opening 8d, and a transparent lid 14 is provided over this opening 8d.

[0024] One end of the operating shaft 6 is located within the knob seat 8, and a knob 12 is fixed to this end. The knob 12 is long in the diametrical direction and is arranged so as to be rotatable approximately 90 degrees inside the cylindrical portion 8a of the knob seat 8, and is positioned approximately horizontally in the locked state R and approximately vertically in the unlocked state F. In the unlocked state F, the knob 12 covers part of the transparent cover 14, but more than half of it is exposed.

[0025] The outer seat 9 forms the edge of the other end of the through hole Ta and has a cylindrical portion 9a that fits inside the inner circumference of the other end of the through hole Ta, a flange portion 9b that extends radially outward from one end of the cylindrical portion 9a and abuts against the side surfaces (inner and outer surfaces) of the door panel T, a closing portion 9c that extends radially inward from the other end of the cylindrical portion 9a and closes the through hole Ta, and two female screw cylinders 9d that protrude from the closing portion 9c into the through hole Ta. The upper part of the closing portion 9c is cut out to form an opening 9e.

[0026] The two female screw tubes 9d of the outboard seat 9 are arranged to pass through the main body case 3, and a screw 17 that passes through the closing portion 8c of the knob seat 8 is screwed into them.By screwing in this screw 17, the flange portion 8b of the knob seat 8 and the flange portion 9b of the outboard seat 9 are pressed against the inner and outer surfaces of the door panel T, thereby fixing the main body case 3 to the door panel T.

[0027] The other end of the operating shaft 6 is located within the outer seat 9, and a disassembly indicator 13 is fixed to this other end. Also, a transparent indicator 15 is provided within the cylindrical portion 9a of the outer seat 9 to fill the space between the disassembly indicator 13.

[0028] This transparent indicator 15 is attached to the operation / unlocking indicator member 13, and therefore rotates together with the operation / unlocking indicator member 13 when the operating shaft 6 rotates. The transparent indicator 15 closes an opening 9e formed in the closing portion 9c of the outer seat 9.

[0029] The lock / unlock indicator member 13 has two cutouts 13a formed in the diameter direction on its circular outer periphery, and a lock indicator 16 is provided on the closing portion of the outlet seat 9, which is exposed outward opposite the two cutouts 13a when the lock / unlock indicator member 13 is in the locked state R.

[0030] A coin engagement groove 13b is formed on the outer surface of the lock / unlock indicator 13, and a coin can be engaged in this coin engagement groove 13b to rotate the operating shaft 6. The lock indicator 16 may also be formed on the transparent indicator 15 at a portion that overlaps with the lock / unlock indicator 13.

[0031] The knob seat 8 and outer seat 9 close both ends of the through-hole Ta, but a space with a roughly semicircular or polygonal cross section remains between them and the inner peripheral surface of the through-hole Ta at the upper rear of the main body case 3, and a cylindrical body Ha with a roughly semicircular or polygonal cross section is inserted into this space. This cylindrical body Ha is made of a shiny metal, and its inner surface is a light-reflecting surface, creating an optical path that allows light to pass through easily.

[0032] This cylindrical body Ha can be made of synthetic resin, but it is preferable to plate the inner surface with metal so that the light that enters the interior can be sufficiently reflected without being absorbed.

[0033] The transparent cover 14 provided in the opening in the knob seat 8, the cylinder Ha in the through-hole Ta, the opening 9e in the outer seat 9, and the transparent indicator 15 are arranged in a straight line to form a light exposure path H that exposes the light from the inside or outside of the door panel T to the opposite side. The part of the transparent indicator 15 facing the opening 9e serves as a light window that exposes the light from inside the room to the outside.

[0034] When a user enters a room, turns on the light, and turns knob 12 approximately horizontally as shown in Figure 1, operating shaft 6 is rotated to advance sickle tip 5b of sickle member 5 to set the door in locked state R, and notch 13a of lock / unlock indicator member 13 exposes lock indicator 16. At this time, light exposure path H opens over its entire length, and is exposed through the light window above lock indicator 16, indicating that the door is locked in the same way as lock indicator 16, emphasizing the lock state R.

[0035] When the knob 12 is rotated from a substantially horizontal position to a substantially vertical position, the operating shaft 6 is rotated to move the sickle tip 5b of the sickle member 5 back to the unlocked state F, and the lock / unlock indicator member 13 hides the lock indicator 16. At this time, if the user forgets to turn off the lights in the room, the knob 12 covers a part of the transparent cover 14 but exposes more than half of it, so the light exposure path H remains open over the entire length, and although the lock / unlock indicator 16 is hidden by the lock / unlock indicator member 13, its upper side is exposed through the light window of the transparent indicator 15, so that it can be seen from outside the room that the lights have been turned off.

[0036] In the above-described embodiment, the door panel T is formed with a through-hole Ta penetrating from its inner to outer surfaces, and a storage hole Tb that communicates from this through-hole Ta to the front surface of the door panel T, and the hook lock device comprises: a main case 3 that is inserted into the storage hole Tb from the front surface of the door panel T; a sickle member 5 that is housed in this main case 3 and has a substantially L-shaped sickle tip 5b; an operating shaft 6 that penetrates the main case 3; an interlocking mechanism 7 that converts the rotation of the operating shaft 6 into the movement of the sickle member 5 so that the sickle tip 5b moves in and out of the main case 3; a knob seat 8 and an outlet seat 9 that are attached to the inner and outer surfaces of the door panel T and are connected to each other so as to form both ends of the through-hole Ta; a knob 12 that is fixed to one end of the operating shaft 6 within the knob seat 8; and an unlocked indicator 13 that is fixed to the other end of the operating shaft 6 within the outlet seat 9. A light exposure path H that exposes light from the inside or outside of the door panel T to the opposite side is formed in the through-hole Ta between the knob seat 8 and the outlet seat 9.

[0037] With this configuration, even if you forget to turn off the light inside the door panel T, you can notice it from outside the door panel T through the light exposure path H.

[0038] In the embodiment, the light exposure path H is formed by a cylindrical body Ha having a substantially semicircular or polygonal cross section, the inner surface of which is a light reflecting surface, and is disposed above the main body case 3 .

[0039] This configuration ensures that even a small amount of light left on inside the door panel T can be exposed to the outside of the room.

[0040] Furthermore, in the embodiment, a transparent cover 14 that closes one end of the light exposure path H is provided inside the knob seat 8.

[0041] This configuration can prevent water, dust, etc. from entering the light exposure path H on the knob base 8 side.

[0042] Furthermore, in the embodiment, a transparent indicator 15 is provided in the outer seat 9 to fill the space between the outer seat 9 and the solution indicator member 13 and to close the other end of the light exposure path H.

[0043] This configuration can prevent water and dust from entering the light exposure path H on the outer seat 9 side. Furthermore, in the above embodiment, the lock / unlock indicator member 13 has a notch 13a formed on its circular outer periphery, and the outer seat 9 is provided with a lock indicator 16 that is exposed outward opposite the notch 13a when the lock / unlock indicator member 13 is in the locked state R.

[0044] With this configuration, in the locked state R, the lock indicator 16 can be confirmed from outside the room, and at the same time, the light exposure of the light exposure path H can be confirmed near the lock indicator 16, and in the unlocked state F, the lock indicator 16 cannot be confirmed from outside the room, but the light exposure of the light exposure path H can be confirmed near the lock indicator 16, and it can be confirmed that the lights inside the door panel T have been left on.

[0045] The present invention is not limited to the above-described embodiment, and the shapes, configurations, and combinations of the components can be changed.

[0046] For example, although the hook lock device 1 is applied to the door panel T of a sliding door, it may also be applied to a door that swings open and closes.

[0047] The knob seat 8 and the outer seat 9 are entirely made of opaque synthetic resin, but the entirety or at least the closing portions 8c, 9c may be made of transparent synthetic resin so that the openings 8d, 9e do not have to be specially made. [Explanation of symbols]
