Abstract

PROBLEM TO BE SOLVED: To easily check a locked state after going out.
[Solution]
When locking, the key K fixed to the key holder 100 is inserted into the keyhole of the cylinder. When the key K is inserted into the keyhole, the tip of the knock shaft 51 hits the cylinder, and the knock shaft 51 is pushed into the housing 1 by pushing the key K further. The knock shaft 51 operates on the same principle as the knock ballpoint pen, and once the knock shaft 51 is pushed in, it remains pushed into the housing 1 even when the key K is removed from the keyhole. Thus, the user can check whether or not the user is locked even after going out.

Description

The present invention relates to a key holder for confirming locking of a lock used for a door of a house or a condominium, a door of a doorway or a door of a locker.

  Conventional rotary cylinders are locked by inserting a key into the keyhole of the cylinder, rotating it by a predetermined angle, and then pulling out the key. However, if this became a habit, there was a problem that it was assumed that it was locked unconsciously even though it was not locked. In particular, in a house where an elderly person or the like lives, an apparatus that can easily determine that the user has been locked on the go has been desired.

In addition, there are a device for confirming by operating the lock confirmation device with electricity (Japanese Patent Laid-Open No. 2003-184361) and a device for attaching the lock confirmation device to the lock unit (Japanese Patent Laid-Open No. 2000-248789). Both were complicated and expensive.

  FIG. 1 is a perspective view showing a key holder according to Embodiment 1 of the present invention. In this key holder 100, the handle portion of the key K is fixed in the housing 1, and the cut K 1 of the key K protrudes from the housing 1. Further, a knock type locking confirmation mechanism 50 is provided beside the notch K1 of the key K. Here, the knock type means a method that maintains the depressed state when the knock shaft 51 is pressed once and returns to the original state when the knock shaft 51 is pressed again. The upper surface of the housing 1 is provided with a hole 2 that constitutes a display unit that indicates a locked state. The key ring 100 can be used for a dimple key as well as a normal key.

  2 is a top view of the housing in a developed state, FIG. 3 is a bottom view thereof, and FIG. 4 is a side view thereof. The housing 1 is made of resin and is integrally formed by injection molding. The front part 3 and the back part 4 of the housing 1 are connected by a hinge part 5 and can be bent by the hinge part 5. A hole 2 that constitutes a display unit is provided in a portion of the housing 1 in which the locking confirmation mechanism of the front part 3 is built. Inside the front part 3 and the back part 4 of the housing 1, a storage and fixing frame 6 for the key K is formed. The storage fixing frame 6 is preferably set to have a shape and size that can store as many types of handle portions as possible. In the example of FIGS. 2 and 3, the storage fixing frame 6 has an elliptical shape. A double-sided tape 7 for fixing the handle portion of the key K is attached to the inside of the storage fixing frame 6.

On the inner surface of the back part 4 of the housing 1, a pair of protrusions 8 for fixing the sleeve for incorporating the lock confirmation mechanism 50 and a protrusion 9 for supporting the spring and supporting the moving member are provided. . Further, as shown in FIG. 4, a cutout portion 10 is provided on the protruding side of the key K of the housing 1 at a portion where the cutout portion K1 of the key K is located. Further, a hole 11 through which the knock shaft 51 of the locking confirmation mechanism 50 passes is provided on the side.

  FIG. 5 is a configuration diagram illustrating an example of the locking confirmation mechanism. The locking confirmation mechanism 50 rotates around the knock shaft 51 that protrudes from the housing 1 and abuts against a cylinder (not shown), the sleeve 52 that is fixed to the housing 1, and the shaft 53. A moving member 56 having a protrusion 55 arranged at a predetermined angle around the periphery and a spring 57 that presses the moving member 56 are configured. The knock shaft 51 has a hollow shaft shape as indicated by a dotted line in the figure, one side of which has a bottomed flange shape, and the other side has a plurality of peaks 58 that contact the projection 55 of the moving member 56. Shape. The sleeve 52 is fixed to the housing 1 and further has grooves 59 and 60 having different axial depths. The shallow groove 59 has an inclined valley. The moving member 56 is rotatable by inserting one of the small-diameter shafts 53 into the hollow portion of the knock shaft 51 and inserting the other into a hole provided in the protrusion 9 on the back 4 of the housing 1. It is supported so as to be movable in the axial direction. Further, the protrusion 55 of the large-diameter portion 54 is formed obliquely on the side facing the sleeve 52 and engages with the grooves 59 and 60 of the sleeve 52. The spring 57 is disposed between the protrusion 55 and the large diameter portion 54.

  6 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 7 is a cross-sectional view taken along the line BB in FIG. As shown in FIG. 6, the lock confirmation mechanism 50 is disposed inside the housing 1. Specifically, the knock shaft 51 is inserted into the hole 11 of the housing 1, the shaft 53 of the moving member 56 is inserted into the hole of the protrusion 9, and the sleeve 52 is sandwiched between the protrusions 8 and enters the housing 1. It is fixed. A part of the knock shaft 51 is colored as a mark 61, which is located at a position corresponding to the hole 2 of the housing 1 and can be seen from the hole 2. FIG. 6 shows a state in which the knock shaft 51 is not pushed, and the mark 61 can be seen from the outside of the housing 1 through the hole 2 at that time. When the knock shaft 51 is pushed in, the mark 61 moves, so that the mark 61 cannot be seen through the hole 2. The user decides when the mark 61 is visible as being locked (or not locked). Further, as shown in FIG. 7, the key K is housed in the housing fixing frame 6 of the housing 1, and the handle portion is fixed by the double-sided tape 7 from both sides. The double-sided tape 7 is affixed on a pedestal 12 formed inside the housing 1. Further, in a state where the key K is fixed, the cut portion K1 protrudes outside through the cutout portion 10 of the housing 1.

FIG. 8 is an explanatory view showing the operation of this key holder. When locking, the key K fixed to the key holder 100 is inserted into the key hole of the cylinder C. In this state, the color seen from the hole 2 of the display unit is, for example, red. When the key K is inserted into the keyhole, the tip of the knock shaft 51 hits the cylinder C, and the knock shaft 51 is pushed into the housing 1 by pushing the key K further. The knock shaft 51 operates on the same principle as the knock ballpoint pen, and once the knock shaft 51 is pushed in, it remains pushed into the housing 1 even when the key K is removed from the keyhole. The color seen from the hole 2 of the display part at that time is white (or the color of uncolored raw material). Thus, the user can confirm whether or not the user has locked. In the example of the figure, when the knock shaft 51 is pushed in and the color of the display portion is white, the lock is locked. When going out, when checking whether or not the door is locked, the position of the knock shaft 51 and / or the color of the display portion are determined.

  On the other hand, when unlocking, the operation is performed in the reverse procedure. That is, the key holder 100 in a state where the knock shaft 51 is pushed in is held, and the cut portion K1 of the key K is inserted into the key hole of the cylinder C. Then, knock shaft 51 hits cylinder C and knock shaft 51 is pushed out. The color that can be seen from the hole 2 of the display section is changed from white to red. This state is an unlocked state. Further, the case where the knock shaft 51 is pushed out may be locked, and the state where the knock shaft 51 is pushed in may be determined as unlocking.

  The operation of the locking confirmation mechanism 50 will be described in detail with reference to FIG. The protrusion 55 of the moving member 56 is in contact with the shallow groove 59 of the sleeve 52 by the action of the spring 57. When the knock shaft 51 is pushed in this state, the crest 58 at the end pushes the projection 55 of the moving member 56, whereby the engagement with the groove 59 of the sleeve 52 is released, and the crest 58 and the projection 55 are disengaged. The inclined portions are pressed against each other, and the moving member 56 rotates in the direction of the arrow in the figure. Then, when the projection 55 stops moving at the valley (between the peaks 58) of the knock shaft 51 and releases the knock shaft 51 in this state, the moving member 56 is pushed by the action of the spring 57, and the projection 55 becomes the sleeve. A slight rotation is made by hitting the inclined portion between the grooves 59 and 60 of the 52, and then it fits into the deeper groove 60. Thereby, the protrusion 55 pushes the end of the knock shaft 51, and as a result, the knock shaft 51 is pushed out.

  When the knock shaft 51 is pushed again, the projection 55 is pushed out again at the end of the knock shaft 51, and the projection 58 is released from the restraint of the groove 60 while the crest 58 and the inclined portion of the projection 55 are pressed against each other. 56 rotates in the direction of the arrow. Subsequently, when the knock shaft 51 is released, the inclined portion of the projection 55 hits the inclined portion of the shallow groove 59 of the sleeve 52 by the action of the spring 57 and is fitted while rotating slightly. In this state, the knock shaft 51 holds the pushed state. The locking confirmation mechanism 50 described above is an example of a knock type mechanism employed in a ballpoint pen or the like, and may be another generally known structure as long as it has a similar action.

  As described above, according to the key holder 100 of the present invention, whether or not the knock shaft 51 is pushed can be easily confirmed by checking whether or not the knock shaft 51 is pushed. Further, the structure is simple because a knock type mechanism is used. In particular, it is possible to check the lock after going out and getting on the vehicle or after a long time. In addition, since no batteries are used, there is no consumption cost, and it is lightweight and easy to carry.

  Further, as shown in FIG. 9, a protective cylinder 62 may be provided around the knock shaft 51 in order to prevent the knock shaft 51 from being accidentally pushed when the key holder 100 is carried. When this protective cylinder 62 is used, a projection 63 as shown in FIG. The protrusion 63 is a cylindrical protrusion having a diameter smaller than the inner diameter of the protective cylinder 62. When the notch K1 of the key K is inserted into the keyhole C1 with the key holder 100, the projection 63 enters the protective cylinder 62 and firmly pushes the knock shaft 51 to the required position. As a result, the knock shaft 51 is kept pushed. When the key K is inserted again into the keyhole C1, the knock shaft 51 is pushed by the protrusion 63 and returns to the original position.

  In addition, it is preferable that the height of the protective cylinder 62 be set such that the head of the knock shaft 51 does not come out when the knock shaft 51 is pushed in. Alternatively, even if the head of the knock shaft 51 comes out, there is no problem as long as the protruding amount is smaller than the pushing amount by which the knock shaft 51 operates.

  FIG. 11 is a perspective view showing a key holder according to Embodiment 2 of the present invention. FIG. 12 is a block diagram showing a key holder according to Embodiment 2 of the present invention. The key holder 200 has a lock confirmation mechanism 250 whose internal structure is a rotary type. The housing 251 is integrally molded with resin in the same manner as in the first embodiment, and includes a housing frame (not shown) similar to that in the first embodiment inside the housing 251. The handle K2 of the key K is fixed in the housing 251 with double-sided tape (both not shown).

  The rotary type locking confirmation mechanism 250 has a rotary disc 252 disposed at the center, and marks 253 of different colors are provided on the surface of the disc 252 at intervals of 90 degrees. The disc 252 rotates about the shaft 254. In addition, a substantially right-angled triangular protrusion 255 is provided on the periphery of the disk 253 in accordance with the position of the mark 253. One side thereof extends outward in the diameter direction of the disc 252, and this portion is in contact with the end of the push-in shaft 256. The push-in shaft 256 passes through a protrusion 257 integrally formed in the housing 251 and the shaft hole 258 of the housing 251 and is movably provided. A spring is provided between the protrusion 257 and the locking portion 259 of the push-shaft 256. 260 is arranged. In addition, a hole 261 is provided in the front portion of the housing 251 at a position where the mark 253 of the disk 252 can be seen. In addition to the coil spring 260, an elastic means such as a leaf spring or a sponge may be used as a means for returning the push-in shaft 256 to its original position.

  13 to 15 are explanatory diagrams showing the operation of this key holder. As shown in FIG. 13, in the state before the key ring 200 is locked, the disc 252 is in a predetermined position, and the color of the mark 253 seen from the hole 261 of the housing 251 is, for example, white. Next, as shown in FIG. 14, when the key K is inserted into the keyhole of the cylinder by holding the key holder 200, the push shaft 256 hits the cylinder and is pushed into the housing 251 by the action of the spring 260. As a result, the end of the push-in shaft 256 hits the protrusion 255 of the disk 252 and rotates the disk 252. By this rotation, the color of the mark 253 visible from the hole 261 changes, for example, red. Subsequently, as shown in FIG. 15, when the key K is removed from the cylinder, the push-in shaft 256 is released from the restraint of the cylinder, and returns to the original position by the action of the spring 260. On the other hand, the disc 252 remains rotated, so that the mark 253 visible from the hole 261 remains red.

  As described above, according to the key holder 200, whether or not the push-in shaft 256 is pushed can be easily confirmed by checking whether or not the push-in shaft 256 is pushed in. In particular, locking can be confirmed even after going out and riding on a vehicle or after a long time. In addition, the key ring 200 of the present invention does not use a battery or the like, so it does not incur consumption costs and is lightweight and easy to carry.

  A protective cylinder 62 as shown in FIGS. 9 and 10 may be provided around the push-in shaft 256. In that case, the protrusion 63 shown in FIG. 10 is used together.

The cover covers the knock shaft 51 or the push-in shaft 256 in order to prevent the knock shaft 51 or the push-in shaft 256 from malfunctioning. The cover is attached to the housing and is always in a state of covering the knock shaft 51 or the push-in shaft 256 by the action of a spring, and this cover is opened when the lock is unlocked. In the case of knock type, open the cover when checking the lock. Also, when unlocking the lock, the cover is opened.

  The locking device may be provided in the housings 1 and 251 of the first or second embodiment, and the knock shaft 51 or the push-in shaft 256 may be prevented from moving unless a predetermined button provided on the housings 1 and 251 is pressed. . For example, the buttons and the claws provided in the casings 1 and 251 may be interlocked so that the claws mesh with a part of the knock shaft 51 or the push-in shaft 256. Next, it is not a knock type or a rotary type, but a simple push shaft and a bottomed cylindrical portion into which the shaft is inserted, and the shaft is fixed with a fitting state that causes a relatively strong frictional force. Anyway. In this case, the shaft that hits the cylinder is pushed in by the force when the key is inserted, and the moving position is held with a frictional force. This state is a locked state, and after confirmation of locking, the shaft may be pulled out and returned. According to the said structure, it can comprise very simply. Moreover, you may provide an LED light in the housing | casing 1 and 251. FIG.
