Description

[Technical Field]

[0001] The present invention relates to a set of components for converting an existing hinged door into a sliding door. [Background technology]

[0002] In Japan, in apartment complexes and condominiums, as well as in detached houses, swing doors are often used as interior fixtures for wall openings. However, swing doors pose a problem in that they can block the movement of wheelchair users and elderly people when they open the door and pass through the opening. Therefore, renovations to sliding doors are sometimes considered to make the building more barrier-free.

[0003] Patent Document 1 below describes a construction method that allows such renovations from hinged doors to sliding doors to be easily realized without large-scale construction work such as changing the wall structure.

[0004] To convert a swing door into a sliding door using this construction method, as shown in Figure 6(a), a swing door 52 is installed in a door frame 51 around the opening in the wall W, and as shown in Figure 6(b), the door 52 is removed and vertical frames 53 and upper frames 54 are fixed to both side edges and the top edge of the door 52 to turn the door 52 into a sliding door 55, and the doorknob 56 is replaced with a pull handle 57.

[0005] Then, the upper end of the door 55 is attached to the front of a slide unit 58 consisting of multiple rows of rails fixed above the opening in the wall W, allowing the door 55 to slide freely against the wall W, thereby completing the conversion from a hinged door to a sliding door, which is a hanging door.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-214013 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with the above construction method, there is a problem in that the slide unit 58 that slides the door 55 is heavy and it is difficult to fix it above the opening in the wall W.

[0008] Furthermore, the rails of the slide unit 58 may be deformed by the load of the door 55, which may cause the door 55 to stop sliding smoothly.

[0009] Furthermore, there is a problem in that processing of the door 52 is required in order to attach the pull tab 57 for the sliding door to the hole left after the door knob 56 for the swing door has been removed.

[0010] Therefore, an object of the present invention is to provide a component set that can be easily remodeled into a sliding door by utilizing components of an existing hinged door, and that can be used to create a hanging door that opens and closes smoothly. [Means for solving the problem]

[0011] In order to solve the above problems, the hinged door to sliding door renovation parts set of this invention has as its basic components an offset upper frame with an upper rail and a hoist, a vertical frame attached to the edge of the door and with a recess that serves as a handle, a lower frame attached to the lower edge of the door and with a guide groove formed on its bottom surface, a lower guide that engages with the guide groove of the lower frame, and a cover plate that covers the hole left by removing the hinged door handle, and by attaching the vertical frame and lower frame to an existing hinged door, the door is converted into a sliding door, and the door is turned into a hanging door that is hung from the offset upper frame (Configuration 1).

[0012] In addition, in the renovation component set of configuration 1, the cover plate is provided with a handle plate portion that is fitted into the recess of the handle of the vertical frame and blocks communication between the inside and outside of the door at the handle (configuration 2).

[0013] In addition, in the renovation component set of configuration 2, the vertical frame is formed with an insertion groove extending above and below the recess of the handle, and the upper and lower parts of the handle plate portion of the cover plate are inserted into the insertion groove of the vertical frame (configuration 3).

[0014] Furthermore, in the renovation component sets of configurations 1 to 3, in addition to the basic components, a strike cover is included to cover the strike hole that engages and disengages the latch attached to the door edge (configuration 4). [Effects of the Invention]

[0015] The swing door to sliding door conversion component set of this invention uses an existing swing door, and attaches a vertical frame that serves as a handle and a lower frame that is guided by a lower guide to turn it into a sliding door.The sliding door is hung from an offset upper frame that is equipped with an upper rail and a hoist, and a cover plate covers the hole where the swing door handle was removed to form the sliding door, so that a swing door can be easily converted into a sliding door, and the sliding door can be made into a hanging door that opens and closes smoothly.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0018] As shown in Figure 5, a normal hinged door has vertical frames 2, 2 corresponding to the leading and trailing ends of the door 1 around the periphery of the opening in the wall W, and an upper frame 3 corresponding to the upper end.A door stop 4 is provided on the inner periphery of the vertical frames 2 and the upper frame 3, and the door 1 is attached to the vertical frame 2 on the trailing end side via hinges 5.

[0019] A handle 6 is attached to the door end of the door 1, and a latch 7 is provided which appears and disappears from the end face when the handle 6 is turned.

[0020] Meanwhile, a strike 8 that receives a latch 7 is embedded in the vertical frame 2 at the door end. The floor F, which forms the lower edge of the opening in the wall W, may have a trim at the boundary of the floor material.

[0021] The renovation component set of this invention is used to remodel a hinged door such as the one described above into a sliding door by reusing door 1, and is a collection of components for converting sliding doors into hanging doors, which are in high demand as barrier-free doors.

[0022] As shown in FIG. 1, the basic components of this reform component set are an outset upper frame 11, a vertical stile 12, a lower stile 13, a lower guide 14, and a cover plate 15.

[0023] The outset upper frame 11 suspends the door 1 so that it can slide freely, and includes an upper rail 11a, two hoisting wheels 11b, and a rail cover 11c. The upper rail 11a is made of metal and guides the hoisting wheels 11b while allowing them to run. The rail cover 11c is made of resin with a decorative surface finish and covers the upper rail 11a.

[0024] The vertical frame 12 is a wooden block attached to the edge of the door 1, and has a recess in the middle that forms the handle 12a, and an insertion groove 12b that extends above and below the recess, so that a separate handle does not need to be prepared.

[0025] The lower frame 13 is a wooden block attached to the lower edge of the door 1, and has a guide groove 13a formed on the bottom surface thereof that extends in the length direction.

[0026] The lower guide 14 is made of metal and engages with the guide groove 13a of the lower frame 13 to guide the sliding of the door 1 while stabilizing it.

[0027] The cover plate 15 is made of a metal or plastic plate and has a bifurcated portion that covers the holes 9 left behind when the handles 6 are removed from both sides of the door 1. The bifurcated portion is integrally provided with a pull tab plate portion 15a that is fitted into a recess in the pull tab 12a of the vertical stile 12 to block communication between the inside and outside of the door 1 at the pull tab 12a. The upper and lower portions of the pull tab plate portion 15a are inserted into the insertion grooves 12b of the vertical stile 12.

[0028] When converting a hinged door such as that shown in Figure 5 into a sliding door using the above-mentioned conversion component set, the door 1 is removed from the vertical frame 2 at the end of the door, and metal fittings such as hinges 5, handles 6, and latches 7 are removed.

[0029] Then, as shown in FIGS. 2 to 4, the bifurcated portion of the cover plate 15 is fitted onto the door leading end portion of the door 1 so as to cover the hole 9 and fixed thereto.

[0030] In this state, the handle plate portion 15a of the cover plate 15 is fitted into the recess of the handle 12a of the vertical frame 12 and inserted into the insertion groove 12b, the vertical frame 12 is attached to the door end side of the door 1, and the bottom frame 13 is attached to the lower edge of the door 1.

[0031] For example, tapping screws can be used to attach the vertical and horizontal frames 12 and 13 to the door 1. In this case, the tapping screws should be included in the renovation component set, and through holes for inserting the tapping screws should be drilled in the vertical and horizontal frames 12 and 13. Then, pilot holes are drilled in the side and bottom edges of the door 1, aligning them with the through holes.

[0032] In this way, when the vertical frame 12 and the bottom frame 13 are attached to the door 1 for a swing door, a door 10 for a sliding door, which is larger in height and width than the door 1, is formed.

[0033] Also, above the opening in the wall W, an upper rail 11a of the offset upper frame 11 is attached so that the opening can be opened and closed as the door 10 slides.

[0034] Then, the hoist 11b fixed to the upper end of the door 10 is supported so as to be freely slidable by the upper rail 11a, the lower guide 14 fixed to the floor F is engaged with the guide groove 13a of the lower frame 13, and the rail cover 11c is fixed so as to cover the upper rail 11a.

[0035] In addition, stoppers (not shown) are provided to restrict the sliding of the door 10 when the door 10 is closed and when it is fully opened.

[0036] This completes the conversion of the swing door to a sliding door using the basic components, but it is also a good idea to attach the strike cover 16 (see Figure 4) included with the basic components to the vertical frame 2 on the door edge side so that it covers the hole in the strike 8 that engages and disengages the latch 7 attached to the door edge of the swing door 1.

[0037] The above-mentioned renovation component set reuses an existing swing door 1, and attaches a vertical frame 12 that forms a handle 12a and a lower frame 13 that is guided by a lower guide 14 to make it a sliding door 10. The sliding door 10 is hung from an offset upper frame 11 that has an upper rail 11a and a hoist 11b, and a cover plate 15 covers the hole 9 where the swing door handle 6 was removed to form the sliding door, so that the swing door can be easily renovated into a sliding door, and the sliding door can be made into a hanging door that opens and closes smoothly.
