Description

Technical Field

[0001] The present invention relates to a trigger unit, a closer device provided with the trigger unit, and a sliding door structure using the closer device.

Background Art

[0002] For a sliding door, a device having a closer that slowly closes the sliding door and a trigger that operates the closer may be used. When such a device is provided in a sliding door that is stored in a door pocket, the trigger needs to be arranged inside the door pocket. Therefore, if the mounting position of the trigger is mistaken due to construction error, the door pocket has to be damaged in order to change the mounting position.

[0003] As a device for solving such a problem, conventionally, a device (sliding door closer set) has been proposed in which a trigger arranged inside a door pocket is integrally coupled to a trigger integrated plate and the trigger integrated plate is attached to a rail outside the door pocket (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the device of Patent Document 1, a groove for inserting the trigger integrated plate is provided in the upper frame rail, and the height of the upper frame rail is increased by that amount. Therefore, if a conventional trigger is used as it is, the trigger cannot reach the closer.

[0006] Therefore, in the device described in Patent Document 1, it is necessary to prepare a separate trigger for the door-side from the trigger for the door-end side. However, if separate triggers are used for the door-side and door-end sides, there is a risk of increased costs due to the increased number of parts and installation errors due to mis-partitioning, and there is room for improvement in this regard.

[0007] The present invention has been made in view of the above circumstances, and its objective is to provide a trigger unit that can unify the trigger on the leading edge side and the trigger on the trailing edge side of the door, thereby eliminating the risk of increased costs due to an increase in the number of parts and construction errors due to mis-partitioning; a closer device equipped with the trigger unit; and a sliding door structure using the closer device. [Means for solving the problem]

[0008] [Trigger Unit] The trigger unit disclosed herein is a unit equipped with a trigger for operating a sliding door closer, comprising an insert that is inserted into the upper frame rail inside a door pocket in which the sliding door is stored, and the insert is provided with a trigger placement section for positioning the trigger unconnected.

[0009] [Closer device] The closer device disclosed herein is a closer device for sliding doors, comprising a closer mounted on a sliding door and a trigger unit of the present invention.

[0010] [Sliding door structure] The sliding door structure disclosed herein is a sliding door structure equipped with a closer device, comprising the closer device of the present invention, an upper frame rail provided in a door pocket in which the sliding door is stored, the upper frame rail provided with a closer passage through which the closer of the closer device moves, and an insertion groove into which an insert body with a trigger positioned in the trigger position is inserted, the closer is mounted on the sliding door, a trigger unit with a trigger uncoupled positioned in the trigger position is inserted into the insertion groove, and the closer is stored in the closer passage. [Effects of the Invention]

[0011] According to the trigger unit, closer device, and sliding door structure disclosed in this application, the trigger on the leading edge of the door and the trigger on the trailing edge of the door can be made common, eliminating the risk of increased costs due to an increase in the number of parts and construction errors due to mis-partitioning.

[0013] (Embodiment) An example of an embodiment of the present invention will be described with reference to the drawings. The closer device 100 of the present invention comprises a closer 10 mounted on a sliding door D and a trigger unit 30 for operating the closer 10.

[0014] As shown in FIGS. 1(a)(b) and FIGS. 2(a)(b), the closer 10 is arranged and used on the upper surface of the sliding door D, and the trigger unit 30 is housed and used in the upper frame rail 50 arranged along the ceiling surface of the door pocket P.

[0015] The closer 10 is a device (soft close device) for decelerating the moving speed of the sliding door D. As shown in FIG. 3, the closer 10 of this embodiment mainly includes a case 11, a damper 12, a damper cover 13, a first locking tool 14, a second locking tool 15, and a spring 16.

[0016] The first locking tool 14 is provided at the tip of the rod 12a of the damper 12 so as to be swingable in the vertical direction via a first joint 17. Similarly, the second locking tool 15 is also provided at the cylinder tube 12b of the damper 12 so as to be swingable in the vertical direction via a second joint 18.

[0017] The spring 16 is provided between the first joint 17 and the second joint 18 so as to be stretchable and contractible. A traveling roller 19 is connected to one end side of the case 11, and a door wheel unit 20 is connected to the other end side.

[0018] The trigger unit 30 is a member for engaging with the first locking tool 14 and the second locking tool 15 of the closer 10 to operate the damper 12. The trigger unit 30 of this embodiment includes an insertion body 31 inserted into the upper frame rail 50 and two triggers 32. Hereinafter, when distinguishing the two triggers 32, the trigger 32 engaging with the first locking tool 14 is called the door tip side trigger 32A, and the trigger 32 engaging with the second locking tool 15 is called the door butt side trigger 32B.

[0019] The insert 31 is a member for positioning the door-end trigger 32B at a predetermined position within the door pocket P. As shown in Figures 4(a) and 4(b), the insert 31 in this embodiment is a long, pipe-shaped (cylindrical) member, and a flattened portion 31a, which is recessed and flattened, is provided at a position closer to the insertion direction forward (door-end side). In this embodiment, the lower surface of the flattened portion 31a functions as a trigger placement portion for positioning the trigger in an uncoupled state.

[0020] The flattened portion 31a is provided with two insertion holes (positioning holes) 31b spaced apart in the longitudinal direction of the insert 31. These positioning holes 31b are the parts into which the projections 32e and 32f formed on the door-end trigger 32B (Figure 6(a)(b)) are accommodated. The positioning holes 31b, by accommodating the projections 32e and 32f, prevent the door-end trigger 32B from shifting position in the longitudinal direction of the insert 31.

[0021] The end of the insert 31 on the door-side is provided with a door-side flat portion 31c that is recessed in the same direction as the flat portion 31a. The door-side flat portion 31c is provided with a screw insertion hole 31d, and the insert 31 is fixed to the upper frame rail 50 and the upper door frame F by screwing a screw 31e inserted through this screw insertion hole 31d into the upper frame rail 50 and the upper door frame F.

[0022] As shown in Figures 5(a) and 5(b), the trigger 32 is provided with a long rectangular base portion 32a that runs along the longitudinal direction of the upper frame rail 50. On the upper surface of the base portion 32a, there are opposing side walls 32b and 32c and a recessed groove 32d between the side walls 32b and 32c. Two protrusions 32e and 32f are provided in the recessed groove 32d, spaced apart in the longitudinal direction of the base portion 32a. Each protrusion 32e and 32f is divided into two by a screw insertion hole 32h (described later).

[0023] In this embodiment, the height of each projection 32e, 32f is made to be the same as or greater than the thickness of the flattened portion 31a of the insert 31. The height of the projections 32e, 32f here refers to the distance from the bottom surface of the recessed groove 32d to the tip of the projection 32e, 32f.

[0024] If the heights of the protrusions 32e and 32f are the same as the thickness of the flattened portion 31a, when the insert 31 with the trigger 32 positioned in the trigger placement area (flattened portion 31a) is inserted into the insertion groove 52 (described later) of the upper frame rail 50, both the tip surfaces of the protrusions 32e and 32f and the upper surface of the flattened portion 31a will abut against the ceiling surface of the upper frame rail 50.

[0025] On the other hand, if the height of the protrusions 32e and 32f is made greater than the thickness of the flattened portion 31a (increased in size), when the insert 31 with the trigger 32 positioned in the trigger placement portion (flattened portion 31a) is inserted into the insertion groove 52 of the upper frame rail 50, the upper surface of the flattened portion 31a does not abut against the ceiling surface of the upper frame rail 50, while the tip surfaces of the protrusions 32e and 32f abut against the ceiling surface of the upper frame rail 50.

[0026] When trigger 32 is used as a door-end trigger 32B, the projections 32e and 32f are fitted into positioning holes 31b formed in the insert 31, thereby preventing the door-end trigger 32B from shifting position in the longitudinal direction of the insert 31. On the other hand, when trigger 32 is used as a door-front trigger 32A, the projections 32e and 32f prevent deformation (bending) when screwing in the door-front trigger 32A.

[0027] A rectangular block-shaped protruding contact portion 32g is provided protruding downward from the lower surface of the base portion 32a. The protruding contact portion 32g is the part that contacts the first locking device 14 or the second locking device 15 of the closer 10 and operates the damper 12 of the closer 10.

[0028] Screw insertion holes 32h are provided at the positions where the protrusions 32e and 32f are located on the base portion 32a. The screw insertion holes 32h are formed to penetrate the base portion 32a and both protrusions 32e and 32f in the thickness direction. These screw insertion holes 32h are holes through which screws are inserted when the trigger 32 is used as a door-side trigger 32A.

[0029] The trigger unit 30 configured in this way is used by being housed in the upper frame rail 50. In this embodiment, the upper frame rail 50 is a member provided along the upper door frame F of the door frame that forms the entrance E and door pocket P, and is provided in a position that includes the inside of the door pocket P where the sliding door D is housed. The upper frame rail 50 can be made up of one part, or it can be made up of two or more parts arranged in series.

[0030] As shown in Figures 6(a) and 6(b), the upper frame rail 50 is provided with a closer passage 51 through which the closer 10 moves, and an insertion groove 52 into which an insert 31 with a trigger 32 positioned on the flat portion 31a is inserted. The closer passage 51 and the insertion groove 52 are in communication, and when the insert 31 and the trigger 32 positioned on the flat portion 31a are inserted into the insertion groove 52, the protruding contact portion 32g of the trigger 32 protrudes into the closer passage 51.

[0031] The door-end trigger 32B is simply resting against the flattened portion 31a of the insert body 31, in other words, it is housed together with the insert body 31 in the insertion groove 52 in a state of being unconnected to the insert body 31. The insert body 31 housed in the insertion groove 52 is screwed in at a position where its leading edge is inside the end face of the door pocket P. This fixes the position of the insert body 31 and installs the door-end trigger 32B in its predetermined position.

[0032] Alternatively, the insert 31 may be positioned so that its front end protrudes outward from the end face of the door pocket P, and then secured with screws at that protruding position (outside the end face of the door pocket P).

[0033] Figure 7 is a cross-sectional view showing the door-side trigger 32A housed in the insertion groove 52 of the upper frame rail 50. Unlike the door-end side trigger 32B, the door-side trigger 32A is directly screwed to the upper frame rail 50 and the upper door frame F without the insertion body 31. In this case, the two protrusions 32e and 32f of the door-side trigger 32A abut against the ceiling surface of the upper frame rail 50, preventing deformation (bending) of the door-side trigger 32A.

[0034] In this embodiment, the sliding door D using the closer device 100 has an upper frame rail 50 provided inside the door pocket P in which the sliding door D is housed, a trigger unit 30 in which a trigger 32 is uncoupled to the flat portion 31a of an insert 31 is inserted into the insertion groove 52 of the upper frame rail 50, and the closer 10 mounted on the sliding door D is housed in the closer passage 51 of the upper frame rail 50.

[0035] The configuration of the above embodiment is merely an example, and the configuration of the trigger unit, closer device, and sliding door structure of the present invention is not limited to the configuration of the above embodiment. The trigger unit, closer device, and sliding door structure of the present invention can be modified as appropriate, such as by adding, replacing, or omitting components, to the extent that the intended purpose can be achieved. As an example, the following modifications can be considered.

[0036] (Variation 1) In the above embodiment, one example is shown where only one flattened portion 31a, which functions as a trigger placement portion, is provided. However, two or more flattened portions 31a can also be provided. Figures 8(a) and 8(b) show an example where two flattened portions 31a are provided spaced apart in the longitudinal direction of the insert 31.

[0037] (Modification 2) In the above embodiment, one example is shown where two positioning holes 31b are provided in the flat portion 31a that functions as a trigger placement area. However, three or more positioning holes 31b can also be provided in a single flat portion 31a. Figures 9(a) and 9(b) show an example where four positioning holes 31b are provided in a single flat portion 31a.

[0038] The insert 31 of the two modified versions described above can also accommodate sliding doors D that have a remaining portion (sliding doors in which a portion of the leading edge of the sliding door D does not fit into the door pocket P when fully opened and protrudes). When there is a remaining portion, it is necessary to install the trigger 32B on the trailing edge side in a different position than when there is no remaining portion, but by configuring the insert 31 in the configuration of each of the modified versions described above, one insert 31 can be used regardless of whether there is a remaining portion or not.

[0039] Furthermore, even if the operating stroke of the closer 10 is different, the installation position of the trigger 32B on the door-end side will also be different. However, by configuring the insert 31 as in the modified examples described above, a single insert 31 can be used to accommodate different operating strokes.

[0040] The embodiments and modifications disclosed herein are illustrative and not intended to restrict the technical scope of the present invention. The technical scope of the present invention is defined by the claims, and includes equivalents to the claims. [Industrial applicability]

[0041] The trigger unit and closer device disclosed herein are particularly suitable for use when attached to a sliding door that is housed in a door pocket, and the sliding door structure disclosed herein is particularly suitable for use as the structure of a sliding door of the type that is housed in a door pocket.
