Description

The present invention can be suitably used for both a sliding door and a sliding door, and can be used for both indoor and outdoor use, and the type of switching operation tool for switching between a closed door state and an open door state is also available. The present invention relates to a sickle lock with a dead bolt that can be appropriately selected.
In general, names such as “door”, “door”, and “door” may be used as a collective term including a variety of fittings that open and close an opening, such as “open door” and “sliding door”. Among them, the “folding door” refers to a door that swings around a hinge, and the “sliding door” refers to a door that moves linearly along the rail. In this specification, when it is necessary to specify the hinged door and the sliding door individually, those names are used, and when both are included, the name “door” is simply used.

  It is well known that sickle locks are used as a kind of mechanism for maintaining a closed state in a sliding door. The sickle lock rotates and turns a switching operation tool (hereinafter referred to as “rotation operation tool”) provided on the sliding door by about 90 °. A sickle is engaged with or detached from a lock holder attached to a surface facing the surface (a door column or a door end surface of a mating sliding door in the case of a double sliding door).

  In order to operate the rotary operation tool, it is necessary to pick a small knob, which may be inconvenient for elderly people, children, and physically disabled people. In order to deal with such inconvenience, in recent years, the rotary operation tool has been abolished, and a switching operation tool that performs a seesaw operation instead (a type like a seesaw switch that selectively operates two button surfaces, Hereinafter, it has been proposed to employ a “seesaw operating tool” (see Patent Document 1).

  The drive of the sickle lock by the seesaw operating tool is to swing the link lever by the swing of the operating rod generated by the seesaw operation, and to transmit the driving force to the base of the sickle held by the swing of the link lever. The mechanism was adopted. It should be noted that the swing angle of the operating rod obtained by the seesaw operating tool is small, and therefore, the link lever can swing at most about 20 to 30 °. However, since the sickle needs to swing about 90 °, a cam acting part for enlarging the swing angle has been adopted as the transmission part from the link lever to the sickle.

  By the way, in this kind of sickle lock, in order to reinforce the sickle when protruding from the door end surface of the sliding door, a dead bolt having a U-shaped cross section arranged so as to sandwich both sides of the sickle is used together. Is known (see Patent Document 2). The deadbolt slides in a direction that linearly appears and disappears from the door end surface of the sliding door while interlocking with the swing of the sickle. In addition, when using a deadbolt, in order to suppress the enlargement and complexity of a structure, suppose that a drive is transmitted from a deadbolt to a sickle, and operation input is performed with respect to a deadbolt. Here, the sliding stroke required for the dead bolt is so large that the swing angle of the operating rod obtained by the seesaw operating tool is insufficient. Therefore, when adopting a dead bolt, adopting a rotary operation tool is limited.

Japanese Patent No. 4599448 JP 2012-219467 A

  When adopting a dead bolt for sickle reinforcement, when adopting a rotary operation tool, 90 ° of the operation range is equivalent to the operation range in which the sickle is raised and lowered from the door end surface of the sliding door, There is no difficulty in the transmission structure. However, when a seesaw operating tool is used instead of the rotating operating tool, the swinging angle of the operating rod generated by the seesaw operation is small as described above, so that it is necessary to adopt a cam mechanism in the transmission structure.

On the other hand, when the dead bolt for sickle reinforcement is employed, the selection of the rotary operation tool as described above is limited. If a seesaw operating tool is used, it is necessary to increase the size and complexity of the structure in order to generate a large swing angle in the operating rod, and also to cause failure. Therefore, conventionally, in sickle tablets, the adoption of a seesaw operating tool and the adoption of a dead bolt were considered to be alternative (cannot be used in combination).

In this way, when using a dead bolt, the seesaw operating tool cannot be used, and as a result, inconvenience in operability is experienced for elderly people, children, and physically handicapped who are not good at picking small knobs. The fact is that it is strong.
However, the present inventor has found that adopting a dead bolt in a sickle lock includes the possibility of using not only a sliding door but also an opening door as an option. However, as described above, the use of the seesaw operation tool and the use of the deadbolt is impossible, and this possibility cannot be pursued.

  The present invention has been made in view of the above circumstances, and can be suitably used for both hinged doors and sliding doors, and can be used for both indoor and outdoor use, It is an object of the present invention to provide a sickle lock with a dead bolt that can appropriately select the type of the switching operation tool for switching between the open door state.

In order to achieve the above object, the present invention has taken the following measures.
That is, a sickle lock with a dead bolt according to the present invention includes a link lever having an output end on a distal end side radially away from a link fulcrum and held swingably, and an output end of the link lever A dead bolt which is link-joined and held so as to be linearly slidable as the link lever swings, and a dead bolt which is linked to the dead bolt at a position away from the output end of the link lever. And a sickle that is swingably held by a sickle fulcrum arranged at another position on the same line side as the link fulcrum as seen from the sliding area, and the dead bolt clamps the sickle from both sides However, the link fulcrum and the sickle fulcrum are formed in a U-shaped cross-section having a groove bottom along a direction opposite to the link fulcrum, and the output end of the link lever is connected to the dead bolt and the sickle. Joining A link joint to the dead bolt is formed at a position approaching or reaching the groove bottom of the dead bolt by being extended deeper in the groove depth direction than the position where the link lever is formed. An input end with an operating rod of a switching operation tool that performs a seesaw operation with respect to a position separated in the radial direction is provided.

  The input end of the link lever is provided on a protruding end extending to the opposite side beyond the link fulcrum when viewed from the output end, and the input end swings around the link fulcrum. The input end is stopped and held corresponding to the lock position and the unlock position where the sickle reaches the area by swinging, and a click operation feeling is generated at an intermediate position between the lock position and the unlock position. A spring provided with a jumping elastic part may be provided.

  The link fulcrum of the link lever is preferably provided with a second input end for fitting and holding the rotary shaft of the rotary operation tool so as to be integrally rotatable.

  The sickle lock with a dead bolt according to the present invention can be suitably used for both a hinged door and a sliding door, and can be used for both indoor and outdoor use. The type of switching operation tool to be switched can be selected as appropriate.

It is a BB line arrow directional view of FIG. The seesaw operation tool is shown, (a) is a side view, and (b) is a rear view. It is a disassembled perspective view of a seesaw operation tool. It is the principal part expanded sectional view which showed the seesaw pin mounting structure of the seesaw operation tool. It is the front sectional view showing a 2nd embodiment of a sickle lock with a dead bolt concerning the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a first embodiment of a sickle lock 1 with a dead bolt according to the present invention. 4 to 6 show a state in which the sickle lock 1 and the seesaw operating tool 2 (switching operating tool for performing seesaw operation) of the first embodiment are combined and attached to the door 3 (for example, a sliding door). Yes.

  The sickle lock 1 is slid in a direction in which the link lever 7 is swingably provided in the lock case 6 and the link lever 7 is joined to the link lever 7 so as to protrude from the lock case 6 (the door tip surface 3a). The deadbolt 8 that is movably held, and is held in a swingable manner in a direction in which the deadbolt 8 is embraced by the deadbolt 8 and protrudes and retracts from the lock case 6 (door surface 3a of the door 3). It has a sickle 9.

In addition, the lock case 6 is provided with a spring 10 for generating a latching biasing force against the link lever 7 at both ends of the swing range when the link lever 7 swings. .
The link lever 7 includes a link fulcrum 15 that protrudes in a disk shape from both the front and back surfaces, and an output end 16 and an input end 17 that protrude from the outer periphery of the link fulcrum 15 in different radial directions. And have. The link lever 7 is configured such that the output end portion 16 and the input end portion 17 are integrated in the lock case 6 by fitting the disc shape of the link fulcrum 15 into a circular hole 20 formed in the lock case 6. It is designed to swing.

In the first embodiment, the link fulcrum 15 is provided with a second input end 21 at the center of the disk shape. The second input end 21 is for fitting a rotation shaft of a rotation operation tool (a switching operation tool that performs a rotation operation: not shown) so that the rotation shaft can be integrally rotated, and more specifically, a through angle. It is configured by forming a hole.
The output end 16 of the link lever 7 is a portion that is linked to the dead bolt 8 and is provided on the distal end side that is radially away from the link fulcrum 15. Specifically, the output end portion 16 is configured by inserting a link pin 24 between the dead bolt 8 and a circular hole 23 that passes therethrough.

On the other hand, the input end portion 17 is a portion that can be engaged with the operation rod 2a of the seesaw operation tool 2 (switching operation tool for performing seesaw operation: see FIGS. 4 to 8). It is provided on the protruding end side that extends to the opposite side beyond the link fulcrum 15 as seen. The projecting length of the input end 17 is shorter than that of the output end 16.
Specifically, the input end portion 17 is configured by forming a trapezoidal hole 25 therethrough. The trapezoidal hole 25 has a lower base (long side) arranged near the rotation center of the link lever 7 and an upper base (short side) arranged far from the rotation center. By arranging the trapezoidal hole 25 in this way, the outer peripheral surface of the operating rod 2a and the inner peripheral edge of the trapezoidal hole 25 with respect to the relative angle change with the operating rod 2a accompanying the swing of the input end 17 The engagement state can be adjusted well (power transmission can be performed smoothly and efficiently).

In the first embodiment, the protruding end side of the input end portion 17 is sharpened in a mountain shape, and two inclined surfaces formed on both sides of the sharpened portion are caused to act as contact surfaces by the spring 10. It is.
In the link lever 7, both the square hole of the second input end portion 21 and the trapezoidal hole 25 of the input end portion 17 are penetrated, so that they can be used from either the front or back of the link lever 7. That is, the front and back surfaces of the lock case 6 can be rotated from either the front or back of the lock case 6 by providing openings that match the square holes of the second input end 21 or the trapezoidal holes 25 of the input end 17. The operation tool and the seesaw operation tool 2 can be assembled. As a result, it is possible to arbitrarily set the opening of the door 3 (which door surface can be selected to attach the rotary operation tool or the seesaw operation tool 2), and the versatility of the sickle lock 1 is enhanced accordingly. ing.

  The deadbolt 8 is disposed in the lock case 6 at the front side (below the link lever 7 in the illustrated example) where the output end 16 of the link lever 7 is directed. The dead bolt 8 has a U-shaped cross section having a pair of front and back side plates 8a and a groove bottom portion 8b connecting the side plates 8a so that the sickle 9 can be clamped from both sides. The groove bottom 8b is provided in an arrangement opposite to the direction in which the link fulcrum 15 of the link lever 7 and the sickle fulcrum 30 of the sickle 9 to be described later are arranged with the sliding region of the dead bolt 8 as a boundary. It has been.

  The output end 16 of the link lever 7 is inserted into the U-shaped groove of the dead bolt 8. The dead bolt 8 and the output end portion 16 of the link lever 7 are link-joined by link pins 24 provided so as to penetrate between the side plates 8a on both sides of the dead bolt 8. As a result, when the link lever 7 swings, the dead bolt 8 slides linearly in response to driving from the output end portion 16. The linear sliding of the dead bolt 8 is guided by fitting a sliding pin 26 penetrating the side plates 8a on both sides in a skewered manner into a long hole 27 provided in the lock case 6.

  The link joint between the link lever 7 and the dead bolt 8 (position where the link pin 24 is provided) is a position where the output end 16 of the link lever 7 approaches or reaches the groove bottom 8b of the dead bolt 8. In other words, the output end 16 of the link lever 7 is extended until it approaches or reaches the groove bottom 8b of the dead bolt 8. By extending the output end 16 of the link lever 7 in this way, the dead bolt 8 was commensurate with this swing when the input end 17 of the link lever 7 was swung about 20 ° to 30 °. It is designed to be able to slide with a large stroke exceeding (scaling) the sliding amount. It goes without saying that the sliding stroke of the dead bolt 8 is set with reference to the fact that the sickle 9 linked to the dead bolt 8 can swing about 90 °.

Specifically, the link joint portion between the link lever 7 and the dead bolt 8 is grooved more than the position at which the sickle 9 is link-joined with the dead bolt 8 (link-joined by the sliding pin 26 as will be described later). The position is deeper in the depth direction.
In addition, in the side plate 8a on both sides of the dead bolt 8, the pin through hole 28 for penetrating the link pin 24 has an inverted L-shaped opening shape. Therefore, when the dead bolt 8 protrudes from the door end surface 3 a of the door 3, even if an external force in the pushing direction acts on the dead bolt 8, the link pin 24 is caught on the inner edge of the pin through hole 28. The structure is such that steep rocking of the link lever 7 is prevented.

The sickle 9 is arranged so as to be on the same line side (above the dead bolt 8 in the example) as the link fulcrum 15 of the link lever 7 is arranged with the sliding area of the dead bolt 8 as a boundary. . Further, as described above, the sickle 9 is arranged to be inserted into a U-shaped groove provided by the dead bolt 8 so that the front and back surfaces are sandwiched between the side plates 8 a of the dead bolt 8.
The sickle 9 is swingably held by a sickle fulcrum 30 disposed adjacent to the link fulcrum 15 of the link lever 7. It goes without saying that the sickle fulcrum 30 is located at a position different from the link fulcrum 15 of the link lever 7. Accordingly, the sickle 9 is retracted from the door tip surface 3 a of the door 3 around the sickle fulcrum 30 to engage with the sickle receiver (the state shown in FIG. 1) and the door tip surface 3 a of the door 3. However, it swings between two positions of the unlock position (state of FIG. 2).

  The sickle 9 is formed with an inclined hole 33 through which a sliding pin 26 (passing between the side plates 8a on both sides in a skewered manner) that guides the linear sliding of the dead bolt 8 is formed. The sickle 9 and the dead bolt 8 are linked by the relationship between the moving pin 26 and the inclined hole 33. The inclined hole 33 has a cam action for causing the sickle 9 to swing around the sickle fulcrum 30 by linear sliding of the dead bolt 8.

Thus, with the linear sliding of the dead bolt 8 caused by the swinging of the link lever 7, the sickle 9 also swings in accordance with the sliding amount of the dead bolt 8 (including between the two positions of the lock position and the unlock position). Sway).
The spring 10 is formed by projecting the spring legs on both sides of the coil spring radially outward, and one spring leg engages with an appropriate position (inner side surface in the illustrated example) in the lock case 6. The other spring leg is arranged so as to contact and interfere with the input end portion 17 (a portion sharpened in a mountain shape) of the link lever 7 that swings in the lock case 6, and is attached to the lock case 6 in this state. .

  When the spring legs of the spring 10 come into contact with two angled slopes provided at the input end 17 of the link lever 7, the swing of the link lever 7 is stopped and regulated. At the time of this stop, the sickle 9 is when it reaches the locked position or when it reaches the unlocked position. That is, with the contact interference of the spring 10 with the link lever 7, the sickle 9 is stopped and held at two positions, ie, a locked position and an unlocked position.

  In the spring 10, the spring leg that comes into contact with the input end 17 of the link lever 7 is provided with a portion bent in a crank shape. This bent portion is formed in the mountain top portion with respect to the input end 17 during the swinging of the link lever 7 (when the sickle 9 swings between the locked position and the unlocked position). This causes a slight impact that can be overcome while pushing up the spring leg. From this, the bent part provided on one spring leg of the spring 10 constitutes a climbing elastic part 34 for generating a feeling of clicking operation when the link lever 7 is swung.

  As shown in FIGS. 4 to 7, the seesaw operating tool 2 includes an operation member 36 having two button surfaces 35 arranged adjacent to each other in a bent state, and a central portion (both of the operation members 36). The seesaw pin 37 is inserted in a skewered manner into the middle position between the button surfaces 35, and the case 38 supports both ends of the seesaw pin 37 in a state of surrounding the operation member 36 in a frame shape. At the middle position between the two button surfaces 35 (the position of the seesaw pin 37), there is provided an operating rod 2a that protrudes in the shape of a square bar toward the back, and the button surface 35 is selectively selected using the seesaw pin 37 as a fulcrum ( The operation rod 2a swings whenever it is pressed alternately.

  In this seesaw operating tool 2, it is recommended to adopt a structure as shown in FIG. 8 in order to facilitate assembly and prevent unintentional disassembly during use. That is, the seesaw pin 37 is provided with a circumferential groove 41 for fitting the spring ring 40 near one end thereof, and the operation member 36 has a spring ring 40 against one pin holding hole 43 into which the seesaw pin 37 is inserted. The spring insertion recessed part 44 which can be fitted is provided. The spring ring 40 has a diameter smaller than that of the seesaw pin 37 and a diameter larger than that of the circumferential groove 41, and generates a spring force in a reduced diameter direction with respect to an external force to be expanded.

  When such a structure is adopted, the spring ring 40 is fitted in the spring insertion recess 44 of the operation member 36 in advance, and the operation member 36 is assembled in the case 38, and then the pin 38 is inserted into the pin holding hole 43 of the operation member 36 from the outside of the case 38. As shown in FIG. 9, an assembly state in which the spring ring 40 is fitted into the circumferential groove 41 of the seesaw pin 37 with a spring force is inevitably obtained by merely pushing the seesaw pin 37. . In this assembled state (the state shown in FIG. 9), the spring ring 40 hinders the axial movement of the seesaw pin 37, so that the seesaw pin 36 never escapes. There is no such thing as breaking down.

  As is clear from the above detailed description, the sickle lock 1 with a dead bolt according to the present invention is formed in the input end 17 (the trapezoidal hole 25) of the link lever 7 when the door 3 is a sliding door. The operation lever 2a of the seesaw operating tool 2 is combined to be engaged. At this time, the seesaw operating tool 2 has two button surfaces 35 arranged side by side. Since the input end portion 17 of the link lever 7 has a structure in which the trapezoidal hole 25 is penetrated, the seesaw operating tool 2 can be assembled to the door 3 from either the front or back of the door surface.

When a rotation operation tool (not shown) is assembled instead of the seesaw operation tool 2, the rotation shaft of the rotation operation tool is inserted into the second input portion 21 (square hole) provided at the link fulcrum 15 of the link lever 7. Combine to make them. Since the second input end 21 also has a structure in which a square hole is penetrated, the seesaw operating tool 2 can be assembled to the door 3 from either the front or back of the door surface.

Moreover, since the sickle lock 1 of the present invention includes the dead bolt 8, it can be suitably used even when the door 3 is a swing door. Of course, either the seesaw operation tool 2 or the rotation operation tool may be employed. In addition, since the entire lock can have a simple and compact structure, it can be used not only for outdoor use but also for indoor use.
FIG. 10 shows a second embodiment of the sickle lock 1 according to the present invention. The most different point of the sickle lock 1 of the second embodiment from the first embodiment is that one input end 17 is added to the link lever 7 and a total of two input ends 17 are provided.

  The respective input end portions 17 are provided around the link fulcrum 15 with an arrangement interval of 90 ° from each other. Therefore, when the seesaw operating tool 2 is assembled to one input end 17 (the same position as the input end 17 of the first embodiment and the upper side in FIG. 10), the button of the seesaw operating tool 2 is used. Surfaces can be arranged side by side. On the other hand, when the seesaw operating tool 2 is assembled to the other input end 17 (the position added in the second embodiment and the left side in FIG. 10), the button of the seesaw operating tool 2 is used. Surfaces can be arranged so that they are lined up and down.

As described above, the selection of whether the button surfaces of the seesaw operating tool 2 are arranged side by side or vertically can be arbitrarily performed according to the specifications of the door 3 or the needs of the user.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, in the link lever 7, the relative protrusion angles of the input end 17 and the output end 16 are not limited. In addition, the number of input end portions 17 themselves and the number of relative angles in the case where a plurality of input end portions 17 are provided are not limited.

  It is also possible to arrange the link lever 7, dead bolt 8, sickle 9, etc. in the upside down direction (inverted arrangement). In addition, the individual details are not limited at all.
