Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, lock manufacturers regularly improve existing products and introduce new products. On the other hand, they may end the sale of products with decreasing shipments. However, over time, loosening, wear of the movable part, scratches and dirt on the handle become noticeable, and users may wish to replace it with a new one. Therefore, manufacturers prepare a situation where reproduction is possible by storing the molds, jigs, etc. of products whose sales have ended. However, each time the sale of a product ends, the molds and jigs to be stored increase, and the orders for reproduction decrease over time, which is a heavy burden for manufacturers.

[0005] In order to reduce the burden on the manufacturer, the development of a versatile replacement handle is desired. Generally, however, the manufacturer of the lock and the manufacturer of the door are different, and the lock manufacturer needs to design a push-pull lock according to the specifications required by the door manufacturer. One of the design problems is the distance between the upper and lower pedestals. The distance between the upper and lower pedestals varies depending on the door manufacturer and also varies depending on the type of door. Conventionally, it has been difficult to supply a replacement handle that can be attached to doors with different distances between the upper and lower pedestals.

[0006] In view of the above circumstances, an object of the present invention is to provide a replacement handle that can be attached to a plurality of doors with different distances between the upper and lower pedestals.

Means for Solving the Problems

[0007] In order to solve the above problems, a handle device according to the present invention includes a pair of pedestals provided on a door with a space therebetween in the vertical direction, and a grip bridged over the pair of pedestals, and the vertical position of at least one of the pedestals with respect to the grip is changeable.

[0008] The grip or at least one of the pedestals is provided with holes at a plurality of locations in the vertical direction, and the grip and at least one of the pedestals may be fixed using any one of the plurality of holes.

Effects of the Invention

[0009] According to the present invention, it is possible to supply a replacement handle that can be attached to a plurality of doors with different distances between the upper and lower pedestals.

A screw hole 12H extending in the front-rear direction is provided above the positioning projection 12P.

[0019] [Upper pedestal] The upper pedestal 20 (see FIGS. 4 and 5) includes a housing 21, a grip holder 22, and a latch lever 23. The housing 21 is formed in a rectangular parallelepiped shape. An opening 21A is provided on the rear surface of the housing 21. On the rear surface of the housing 21, bosses 21B protruding rearward are provided above and below the opening 21A. A screw hole 21H extending in the front-rear direction is provided at the tip of the boss 21B.

[0020] The grip holder 22 is disposed inside the housing 21. The grip holder 22 is formed in a rectangular parallelepiped shape. The front surface of the grip holder 22 is recessed along the outer peripheral surface of a cylindrical grip 30 described later. At the lower part of the front surface of the grip holder 22, a positioning projection 22P protruding forward is provided. Above the positioning projection 22P, screw holes 22H penetrating in the front-rear direction are provided at two positions, one above the other.

[0021] The latch lever 23 is supported by the housing 21 via a shaft 23S having the left-right direction as the axial direction provided in front of the opening 21A, and is swingable around the shaft 23S. The tip of the latch lever 23 protrudes rearward from the opening 21A. The latch lever 23 includes an engaging portion 23E protruding below the shaft 23S. The engaging portion 23E includes a long hole 23H having the vertical direction as the longitudinal direction. The grip holder 22 includes a projection 22R protruding leftward or rightward. The projection 22R is inserted into the long hole 23H. A torsion coil spring (not shown) is provided on the shaft 23S. The latch lever 23 is urged in the clockwise direction in FIG. 5 by the torsion coil spring. Therefore, the projection 22R is pulled rearward by the engaging portion 23E, and the grip holder 22 is pulled toward the housing 21 side.

[0022] [Grip] The grip 30 is formed in a cylindrical shape having the vertical direction as the longitudinal direction. At the upper part of the grip 30, a screw hole 33 corresponding to the screw hole 22H of the upper pedestal 20 and a positioning hole 34 corresponding to the positioning projection 22P of the upper pedestal 20 are provided. To attach the upper pedestal 20 to the grip 30, the positioning projection 22P is inserted into the positioning hole 34, and the upper pedestal mounting screw 72 is fastened to the screw hole 33 through the screw hole 22H.

[0023] On one side, at the lower part of the grip 30, there are provided a plurality of screw holes 31 corresponding to the screw holes 11H of the lower pedestal 10, and a plurality of positioning holes 32 corresponding to the positioning projections 12P of the lower pedestal 10. The screw holes 31 are an example of the holes according to the present invention. The number of the screw holes 31 and the number of the positioning holes 32 are the same, and in this embodiment, they are three. The plurality of screw holes 31 are arranged at equal intervals in the vertical direction. The plurality of positioning holes 32 are arranged at equal intervals in the vertical direction and at the same interval as the plurality of screw holes 31. Here, the interval means the interval between the centers of the screw holes 31 and the positioning holes 32. The interval between the uppermost screw hole 31 and the uppermost positioning hole 32 is equal to the interval between the screw hole 11H and the positioning projection 12P of the lower pedestal 10.

[0024] To attach the lower pedestal 10 to the grip 30, first, insert the positioning projection 12P into any one of the three positioning holes 32. Thereby, the screw hole 12H is aligned with any one of the three screw holes 31. In FIG. 3, an example where the positioning projection 12P is inserted into the lowermost positioning hole is shown. In this case, the screw hole 12H is aligned with the lowermost screw hole 31. Next, fasten the lower pedestal mounting screw 71 to the screw hole 31 through the screw hole 12H. In this way, by attaching the lower pedestal 10 and the upper pedestal 20 to the grip 30, the outdoor side handle 3 is formed.

[0025] [Indoor side handle] FIGS. 6 and 7 are exploded views showing the lower part of the indoor side handle 4. FIG. 8 is a side view (upper part) and a cross-sectional view (lower part) showing the indoor side handle 4. FIG. 9 is a cross-sectional view showing the II-II cross section of FIG. 8.

[0026] The handle device (indoor side handle 4) includes a pair of pedestals (lower pedestal 40, upper pedestal 50) provided on the door 2 with a space therebetween in the vertical direction, and a grip 60 bridged over the pair of pedestals, and the vertical position of at least one of the pedestals with respect to the grip 60 is changeable. Specifically, it is as follows.

[0027] [Lower pedestal] The lower pedestal 40 (see FIGS. 6 to 9) includes a housing 41, a grip arm 42, and a latch lever 43. In this embodiment, the lower pedestal 40 and the upper pedestal 50 have the same configuration, but the latch lever 43 of the lower pedestal 40 is a dummy.

[0028] The housing 41 is formed in a rectangular parallelepiped shape. An opening 41A is provided on the front surface of the housing 41. Boss holes 41H are provided above and below the opening 41A on the front surface of the housing 11.

[0029] The grip arm 42 protrudes leftward from the rear surface of the housing 41. The base end portion of the grip arm 42 is supported by the housing 41 via a shaft 42S having the vertical direction as the axial direction, and is swingable around the shaft 42S. A torsion coil spring 42C is provided on the shaft 42S. The grip arm 42 is biased rearward by the torsion coil spring 42C.

[0030] The rear surface of the tip of the grip arm 42 is recessed along the outer peripheral surface of a cylindrical grip 60 described later. Positioning protrusions 42P protruding rearward are provided at two positions, upper and lower, on the rear surface of the tip of the grip arm 42. Threaded holes 42H extending in the front-rear direction are provided at two positions, upper and lower, between the two positioning protrusions 42P. The threaded holes 42H are an example of the holes according to the present invention.

[0031] The latch lever 43 is supported by the housing 41 via a shaft 43S having the left-right direction as the axial direction provided behind the opening 41A, and is swingable around the shaft 43S. The tip of the latch lever 43 protrudes forward from the opening 41A. The latch lever 43 includes an engaging portion 43E protruding above the shaft 43S. The engaging portion 43E engages with an engaging portion 42E provided at the base end portion of the grip arm 42. As described above, the grip arm 42 is biased rearward by the torsion coil spring 42C. Therefore, the latch lever 43 is biased in the counterclockwise direction.

[0032] [Upper pedestal] The upper pedestal 50 (refer to FIG. 8) includes a housing 51, a boss hole 51H, a grip arm 52, a latch lever 53, etc. Since the configuration of the upper pedestal 50 is common to that of the lower pedestal 40, the description thereof is omitted.

[0033] [Grip] The grip 60 is formed in a cylindrical shape with the vertical direction as the longitudinal direction. At the lower part of the grip 60, there are provided one screw hole 61 corresponding to the screw hole 42H of the lower pedestal 40 and a plurality of positioning holes 62 corresponding to the positioning protrusions 42P of the lower pedestal 40. Above and below the screw hole 61, the positioning holes 62 are provided at two positions equally spaced in the vertical direction. The distance between the uppermost positioning hole 62 and the third positioning hole 62 from the top is equal to the distance between the two positioning protrusions 42P.

[0034] To attach the lower pedestal 40 to the grip 60, first, insert the two positioning protrusions 42P into any of the four positioning holes 62. As a result, one of the two screw holes 42H is aligned with the screw hole 61. In FIG. 7, an example where the positioning protrusion 42P is inserted into the lower positioning hole 62 is shown. In this case, the upper screw hole 42H is aligned with the screw hole 61. Next, fasten the grip arm mounting screw 73 through the screw hole 42H to the screw hole 61. The procedure for attaching the upper pedestal 50 to the grip 60 is the same. In this way, by attaching the lower pedestal 40 and the upper pedestal 50 to the grip 60, the indoor handle 4 is formed.

[0035] Next, the outdoor handle 3, the indoor handle 4, and the latch lock 5 are attached to the door 2 (refer to FIG. 1). First, attach the latch lock 5 to the door 2 from the rabbet 2A side. On the outdoor side wall surface 2B and the indoor side wall surface 2C of the door 2, there are provided openings 2D for attaching the lower pedestals 10, 40, the upper pedestals 20, 50. After inserting the bosses 11B and 21B into the opening 2D, insert the boss 11B into the boss hole 41H and the boss 21B into the boss hole 51H. Then, by fastening the handle mounting screw 74 to the screw holes 11H and 21H, the outdoor handle 3 and the indoor handle 4 are attached to the door 2.

[0036] When opening the door 2 from the outside, when the grip 30 is pulled forward, the grip 30 falls forward about the axis 12S. At this time, since the protrusion 22R of the grip holder 22 moves forward, the latch lever 23 swings counterclockwise in FIG. 5 and the latch lock 5 is unlocked.

[0037] On the other hand, when opening the door 2 from the inside, when the grip 60 is pushed forward, the grip 60 swings forward about the axis 42S. At this time, since the engaging portion 43E of the latch lever 43 together with the engaging portion 42E of the grip arm 42 moves forward, the latch lever 43 swings clockwise in FIG. 8. Similarly, also in the upper pedestal 50, the latch lever 53 swings clockwise, and as a result, the latch lock 5 is unlocked.

[0038] According to the handle device (outdoor handle 3) according to the present embodiment described above, a pair of pedestals (lower pedestal 10, upper pedestal 20) provided on the door 2 with a space therebetween in the vertical direction, and a grip 30 bridged over the pair of pedestals are provided, and the vertical position of at least one of the pedestals with respect to the grip 30 is changeable. Also, according to the handle device (indoor handle 4) according to the present embodiment, a pair of pedestals (lower pedestal 40, upper pedestal 50) provided on the door 2 with a space therebetween in the vertical direction, and a grip 60 bridged over the pair of pedestals are provided, and the vertical position of at least one of the pedestals with respect to the grip 60 is changeable. According to these configurations, since the distance between the upper and lower pedestals is changeable, an interchangeable handle that can be attached to a plurality of doors 2 having different distances between the upper and lower pedestals can be supplied.

[0039] Also, according to the handle device (outdoor handle 3) according to the present embodiment, the grip 30 is provided with holes (screw holes 31) at a plurality of positions in the vertical direction, and the grip 30 and at least one pedestal are fixed using any one of the plurality of holes. Also, according to the handle device (indoor handle 4) according to the present embodiment, the grip 60 is provided with holes (screw holes 42H) at a plurality of positions in the vertical direction, and the grip 60 and at least one pedestal are fixed using any one of the plurality of holes. According to these configurations, the interval between the upper and lower pedestals can be changed with a simple configuration. Note that instead of the grip 30, a plurality of holes (screw holes 31) may be provided in at least one of the pedestals (lower pedestal 10, upper pedestal 20). Also, instead of the grip 60, a plurality of holes (screw holes 42H) may be provided in at least one of the pedestals (lower pedestal 40, upper pedestal 50).

[0040] The above embodiment may be modified as follows.

[0041] In the above embodiment, an example is shown in which the vertical position of the lower pedestals 10 and 40 with respect to the grips 30 and 60 is changed by selecting the screw hole 31 or the screw hole 42H. However, the position of the lower pedestals 10 and 40 with respect to the grips 30 and 60 may be configured to be changed steplessly. For example, a groove-shaped guide may be provided on either the grip 30 or the lower pedestal 10, and a protrusion that slides along the guide may be provided on the other, and the lower pedestal 10 may be configured to be fixed to the grip 30 using a clamp or the like.

[0042] In the above embodiment, an example is shown in which only the lower pedestal 10 can change its vertical position in the outdoor handle 3. However, the upper pedestal 20 may also be configured to be able to change its vertical position.

[0043] In the above embodiment, an example is shown in which the latch lock 5 is locked and unlocked in conjunction with the displacement of the grips 30 and 60. However, the latch lock 5 may be locked and unlocked in conjunction with a partial displacement of the grips 30 and 60. For example, a lever that displaces in the opening and closing direction of the door 2 may be provided on the rear side of the grips 30 and 60, and the latch lock 5 may be locked and unlocked in conjunction with the displacement of the lever.

[0044] In the above embodiment, an example was shown in which at least a part of the grips 30 and 60 is displaceable in the opening and closing direction of the door 2 with respect to the pedestal. However, the present invention may be applied to a configuration in which the entire grips 30 and 60 do not displace with respect to the pedestal. In other words, the present invention may be applied to a handle device in a form other than a push-pull lock.

[0045] In the above embodiment, an example was shown in which the grip 30 and the lower pedestal 10 are fastened by the lower pedestal mounting screw 71 to any one of the plurality of screw holes 31. However, instead of the lower pedestal mounting screw 71, a member such as a rivet may be used to fix the grip 30 and the lower pedestal 10. The same applies to the grip 60 and the lower pedestal 40.
