Description

The present invention relates to a base unit for fixing a handle for operating a latch of a latch lock to a door.

In a door with a latch lock, a handle for operating the latch of the latch lock is attached to the door via a base. Such a pedestal is disclosed, for example, in Patent Document 1.
Patent Literature 1 discloses a door handle mounting seat that allows one-touch fixing of handle mounting seats arranged on both sides of a door. That is, one handle mounting seat is provided with a pipe shaft having a press-fit hole, and the other handle mounting seat is provided with a press-fit shaft. The door handle mounting seat disclosed in Patent Document 1 is configured such that both handle mounting seats are fixed by press-fitting the press-fitting shaft into the press-fitting hole of the pipe shaft.
The door handle mounting seat of Patent Literature 1 is said to be able to accommodate various door thicknesses by adjusting the insertion/removal amount of the press-fitting shaft into the press-fitting hole of the pipe shaft.

JP-A-7-324529

By the way, the door handle mounting seat disclosed in Patent Document 1 corresponds to the thickness of the door by adjusting the insertion/removal amount of the press-fitting shaft into the press-fitting hole of the pipe shaft. However, when attaching the door handle attachment seat as disclosed in Patent Document 1 to the door, the operator must manually hold the seat at the attachment position of the door.
Also, if the amount of insertion and removal is different, the length of contact between the pipe shaft (mounting seat on one side) and the press-fit shaft (mounting seat on the other side) will be different. There is a dissatisfaction that the strength against the external force in the direction of separation from the door varies depending on the thickness of the door, and the quality cannot be kept constant.

Therefore, the present invention can handle doors with different thicknesses, eliminates the need for an operator to manually hold the pedestal when attached to the door, and maintains the same fixing strength regardless of the thickness of the door. To provide a pedestal unit for a handle of a latch lock which can be fixed together with one touch.

The base 10 is provided with engaging recesses 21a to 21d at positions above and below the through hole 10a as viewed in FIG. The engaging recesses 21a to 21d are portions obtained by cutting out a part of the base 10, and engage with the engaging protrusions 20a to 20 of the main body 5a. The legs 19a and 19b are provided on both sides of the base 10 across the through hole 10a (both sides in the left-right direction in FIG. 2).

Sliding portions 26a and 26b are provided near the leg portions 19a and 19b of the base portion 10 . The interval between the sliding portions 26a and 26b matches the interval between the guide grooves 18a and 18b of the main body 5a. The width of the sliding portions 26a and 26b (the size in the vertical direction as viewed in FIG. 2) is just large enough to fit into the guide grooves 18a and 18b.

The leg portions 19a and 19b have a length from the base end side (base portion 10 side) to the tip end side. Specifically, the legs 19a and 19b have a length that allows them to pass through the door 1 and engage with a pedestal 4b, which will be described later. The proximal ends of the legs 19a and 19b are fixed to the base 10, and the distal ends of the legs 19a and 19b are free ends forming engaging portions 8a and 8b. The engaging portions 8a and 8b are continuous with base end portions of the leg portions 19a and 19b via constricted portions 12a and 12b. That is, the constricted portions 12a and 12b are provided at positions adjacent to the proximal end side of the engaging portions 8a and 8b. The constricted portions 12a and 12b are portions of the leg portions 19a and 19b that are partially thin (having a small outer shape). The engaging portions 8a and 8b have a spherical outer shape (spherical surface shape) except for connecting portions with the constricted portions 12a and 12b.

The legs 19a and 19b have the same size (length) and shape, are parallel to each other, and stand upright with respect to the base 10. As shown in FIG. That is, the base 10 constitutes an overhanging portion that overhangs the leg portions 19a and 19b in a direction crossing (perpendicular to) the longitudinal direction of the leg portions 19a and 19b.

The legs 19a and 19b can be inserted through the insertion holes 11a and 11b of the main body 5a at the same time. That is, the legs 19a and 19b stand up from the base 10 at the same intervals as the insertion holes 11a and 11b.

A compression spring 9 (biasing means) is provided between the main body 5 a and the guide body 6 . The compression spring 9 is fitted onto the cylindrical portion 16 of the main body 5a and has one end in contact with the base portion 15 . The other end of the compression spring 9 is in contact with the base portion 10 (overhanging portion) of the guide body 6 .

The pedestal 4a having such members is configured as follows. That is, the compression spring 9 is fitted on the cylindrical portion 16 of the main body 5a, and both ends of the compression spring 9 are in contact with the base portion 15 of the main body 5a and the base portion 10 of the guide body 6, and the compression spring 9 is compressed. there is That is, the base portion 15 of the main body 5a and the base portion 10 of the guide body 6 are urged by the compression spring 9 in directions away from each other.

Leg portions 19a and 19b of the guide body 6 are inserted through the insertion holes 11a and 11b of the main body 5a, and as shown in FIG. . Furthermore, the sliding portions 26a and 26b of the guide body 6 are fitted and engaged with the guide grooves 18a and 18b of the main body 5a.
Thereby, the main body 5 a can move along the leg portions 19 a and 19 b of the guide body 6 . In other words, the legs 19a and 19b can move along the insertion holes 11a and 11b, and the main body 5a and the guide body 6 can relatively move in the longitudinal direction of the legs 19a and 19b.

Further, the engaging projections 20a to 20d of the main body 5a and the engaging recesses 21a to 21d of the guide body 6 are engaged as shown in FIG. 4(a). That is, the main body 5a and the guide body 6 are biased by the biasing force of the compression spring 9, but the engagement of the engaging projections 20a to 20d and the engaging recesses 21a to 21d causes the body 5a to move away from the guide body. 6 is prevented from falling out. In other words, the engaging protrusions 20a to 20d have a retaining function to prevent the guide body 6 from separating from the main body 5a.

On the other hand, the pedestal 4b has a main body 5b, as shown in FIGS. The main body 5b is a member having an oval shape.
A through hole 22 is provided in the center of the main body 5b. The portion of the main body 5b where the through hole 22 is provided is thicker than the peripheral portion of the main body 5b.
Holding portions 7a and 7b are provided at both ends of the main body 5b in the longitudinal direction. That is, the holding portions 7a and 7b are provided on both sides of the through hole 22 in the main body 5b.

The holding portion 7a has a plurality of (four in this embodiment) holding pieces 13a standing upright with respect to the main body 5b. Each holding piece 13a is formed of a thin plate having a substantially rectangular shape. Each holding piece 13a is arranged along the same imaginary circle on the main body 5b. That is, the holding portion 7a has a structure in which the holding pieces 13a are arranged in a ring shape and connected to the main body 5b. Further, each holding piece 13a is a plate piece that tapers from the connecting portion (base portion) to the main body 5b toward the distal end side. A connection portion (base portion) of each holding piece 13a with the main body 5b is curved along the circumference of the arranged imaginary circle.

The tip side of each holding piece 13a is curved inward. That is, the diameter of the virtual circle on which the tip of each holding piece 13a is arranged is smaller than the diameter of the virtual circle on the main body 5b on which the base of each holding piece 13a is arranged. The tip of each holding piece 13a constitutes a receiving portion 23a.

In the present embodiment, holes 25a are provided in portions of the main body 5b surrounded by the holding pieces 13a. That is, each holding piece 13a is arranged around (for example, edge) the hole 25a of the main body 5b. The hole 25a functions as a housing portion 27a that houses the engaging portion 8a.

As shown in FIG. 7A, the receiving portion 23a is provided with a surface (inclined surface or tapered surface) inclined in the thickness direction of the plate-shaped holding piece 13a. In this embodiment, a tapered surface 24 is provided on the receiving portion 23a. The tapered surface 24 is a conical surface that inclines from the inner peripheral side to the outer peripheral side toward the distal end side of the holding piece 13a.

The holding portion 7b has a structure similar to that of the holding portion 7a, and redundant description is omitted. Each member and each portion constituting the holding portion 7b is denoted by "b" instead of "a" in each member and each portion of the holding portion 7a.

The pedestals 4a and 4b of the pedestal unit 4 described above are combined as follows.
In the base 4a, a compression spring 9 is arranged between the main body 5a and the guide body 6, as shown in FIGS. The compression spring 9 is fitted on the tubular portion 16 of the main body 5a, and one end of the compression spring 9 abuts on the base portion 15 of the main body 5a. Also, the other end of the compression spring 9 is in contact with the base portion 10 of the guide body 6 . The legs 19a and 19b of the guide body 6 are inserted through the insertion holes 11a and 11b of the main body 5a. When the guide body 6 is inserted through the main body 5a, the state shown in FIGS. 4(a) and 4(b) is obtained. In this state, the main body 5a can move along the legs 19a and 19b of the guide body 6. As shown in FIG. Further, the main body 5a and the guide body 6 are biased away from each other by the biasing force of the compression spring 9. As shown in FIG.

As shown in FIG. 4A, the holding portions 7a and 7b of the pedestal 4b are opposed to the engaging portions 8a and 8b which are the distal end portions of the legs 19a and 19b inserted through the main body 5a. That is, the interval between the engaging portions 8a and 8b and the interval between the holding portions 7a and 7b match. Then, when the pedestals 4a and 4b approach each other, the engaging portions 8a and 8b of the pedestal 4a engage with the holding portions 7a and 7b of the pedestal 4b, and the two pedestals 4a and 4b are joined.

Here, how to connect the two pedestals will be described with reference to FIG.
The diameter of the imaginary circle in which the receiving portion 23a (23b) at the tip of each holding piece 13a (13b) of the holding portion 7a (7b) shown in FIGS. It is smaller than the diameter of joint 8a (8b). The diameter of the engaging portion 8a (8b) is equal to or slightly smaller than the diameter of the virtual circle on the main body 5b on which the base side of each holding piece 13a (13b) of the holding portion 7a (7b) is arranged. It is larger than the diameter of the imaginary circle on which 23a (23b) is arranged. Further, a tapered surface 24 is provided on the receiving portion 23a (23b).

When the engaging portion 8a (8b) engages with the holding portion 7a (7b), the spherical surface of the engaging portion 8a (8b) first contacts the tapered surface 24 first. At this time, a part of the engaging portion 8a (8b) is inside the imaginary circle in which the receiving portion 23a (23b) is arranged. When the engaging portion 8a (8b) moves further toward the holding portion 7a (7b), the spherical surface of the engaging portion 8a (8b) presses the tapered surface 24 outward (toward the outer periphery) to receive it. The portion 23a (23b) is pushed and spread. That is, the engaging portion 8a (8b) enters into the accommodating portion 27a (27b) inside the holding portion 7a (7b) while expanding the receiving portion 23a (23b) (FIGS. 7C and 7D). ).

As shown in FIGS. 5(a), 5(b), and 7(c), when the widest portion (diameter portion) of the engaging portion 8a (8b) passes through the receiving portion 23a (23b), , the receiving portion 23a (23b) is pushed outward. Therefore, at this time, the diameter of the imaginary circle in which the receiving portion 23a (23b) is arranged is expanded (enlarged) to be the largest.

When the widest portion (diameter portion) of the engaging portion 8a (8b) presses against the tapered surface 24 and passes through the receiving portion 23a (23b), the receiving portion 23a (23b) does not expand any further. That is, as shown in FIG. 7(d), when the widest portion of the engaging portion 8a (8b) passes through the receiving portion 23a (23b) and is accommodated in the accommodating portion 27a (27b), the original posture is restored. The virtual circle in which the receiving portion 23a (23b) is arranged becomes smaller due to the elasticity of each holding piece 13a (13b) that tries to return to the normal position.

The virtual circle in which the receiving portion 23a (23b) is arranged is smaller than the diameter of the engaging portion 8a (8b). It is held by holding pieces 13a (13b) so as to be embraced. That is, the engaging portion 8a (8b) is held by the holding portion 7a (7b). In other words, the engaging portion 8a (8b) engages with the holding portion 7a (7b), and the receiving portion 23a (23b) is in close contact with the constricted portion 12a (12b). At this time, both pedestals 4a and 4b are combined and integrated as shown in FIGS. 6(a) and 6(b).

That is, at the position of the receiving portion 23a (23b), a constricted portion 12a (12b) having an outer shape smaller than that of the engaging portion 8a (8b) is arranged, and the receiving portion 23a (23b) is moved by the elasticity of the holding portion 7a (7b). It contracts and abuts on the constricted portion 12a (12b). The receiving portion 23a (23b) at this time is smaller than the engaging portion 8a (8b). Therefore, the engaging portion 8a (8b) is prevented from separating from the holding portion 7a (7b).

In practice, the pedestals 4a and 4b are attached to the surface (outer surface) and back surface (inner surface) of the door 1 (FIG. 1). The thickness of the door 1 is not uniform, and the interval between the pedestals 4a and 4b differs depending on the thickness of the door 1. - 特許庁In the pedestals 4a and 4b according to the present embodiment, the pedestal 4a has the main body 5a and the guide body 6, the guide body 6 is integrated with the pedestal 4b by one touch, and the main body 5a is the leg portion 19a of the guide body 6, 19b can be moved. Therefore, according to the thickness of the door 1, the space|interval of the base 4a (main body 5a) and the base 4b (main body 5b) can be changed. A pedestal 4a can be attached to the surface (outer surface) of the door 1, and a pedestal 4b can be attached to the back surface (inner surface).

Next, with reference to FIGS. 6(a), 6(b), 8(a), and 8(b), a description will be given of how the intervals between the pedestals 4a and 4b (main bodies 5a and 5b) change. .

In the state shown in FIGS. 6(a) and 6(b), the compression spring 9 is stretched to the maximum, and the base 15 of the main body 5a is separated from the base 10 of the guide body 6 to the maximum. As a result, the space between the pedestal 4a (main body 5a) and the pedestal 4b (main body 5b) is the narrowest.

On the other hand, in the states shown in FIGS. 8(a) and 8(b), the compression spring 9 is compressed to the maximum, and the base 15 of the main body 5a is closest to the base 10 of the guide body 6. are doing. As a result, the distance between the pedestal 4a (main body 5a) and the pedestal 4b (main body 5b) is the widest.

By changing the distance between the pedestal 4a (main body 5a) and the pedestal 4b (main body 5b) in this way, both the pedestals 4a and 4b can be attached to the door 1 according to the thickness of the door 1.

Moreover, the pedestals 4a and 4b are always biased toward the door 1 by coupling the holding portions 7a and 7b and the engaging portions 8a and 8b to each other. That is, the biasing force of the compression spring 9 acts in a direction to prevent the pedestals 4a and 4b from separating from the door 1. As shown in FIG. In this state, when the pedestals 4a and 4b are fixed to the door 1 by fastening means (for example, screws) (not shown), the pedestals 4a and 4b are attached to the door 1 satisfactorily.

That is, when attaching the pedestals 4 a and 4 b to the door 1 , the operator does not need to hold the pedestals 4 a and 4 b at the attachment position of the door 1 . Therefore, the compression spring 9 (biasing means) can exert a temporary fixing function when attaching both the pedestals 4a and 4b to the door 1. As shown in FIG. Thereby, the operator can attach the pedestals 4a and 4b to the door 1 satisfactorily.

In this embodiment, the leg portions 19a and 19b of the guide body 6 are inserted through the insertion holes 11a and 11b of the main body 5a. Here, instead of the insertion holes 11a and 11b, the side walls of the insertion holes 11a and 11b may be partly missing in the axial direction. That is, the insertion holes 11a and 11b may be replaced with grooves or recesses (recesses) whose bottoms are on the cylindrical portion 16 side, and the legs 19a and 19b may be fitted into these.
