However, in a structure where a metal blocking material snaps into engagement with a frame material, making the engagement part thin causes rattling, while making it thick makes insertion difficult. Also, fastening metal material with screws is poor in terms of workability and design.

The present invention was made in consideration of the above problems, and aims to provide a fixture that makes it easy to attach sealing material to grooves in shaped members.

In order to solve the above problems and achieve the objective, the fitting according to the present invention is a fitting comprising a shaped member that forms part of a frame or a shoji screen and has a groove formed on its visible surface in the longitudinal direction, and a sealing member that fits into the groove to seal it, the shaped member having engagement protrusions that protrude in directions approaching each other from both sides in the visible direction of the opening of the groove, the sealing member being an elastic material, and having a lid portion that seals the opening, a fold line formed in the longitudinal direction on the visible surface of the lid portion, and an engagement portion that engages with the engagement protrusions from the back side of the groove.

The fitting sealing material of the present invention is made of a resin elastic material and has folds formed on the visible surface of the lid, making it easy to bend when pushed into the groove and easy to install.

Below, an embodiment of the fitting according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment.

Figure 1 is a cross-sectional view of a fitting 10 according to an embodiment of the present invention. Figure 2 is a vertical-sectional view of a fitting 10 according to an embodiment of the present invention. The fitting 10 is what is called a sliding window, in which an inner screen 14 and an outer screen 16 are arranged so as to be slidable in the left-right direction relative to a frame body 12. The frame body 12 is formed into a rectangular shape by framing left and right vertical frames (shaped members) 18, a lower frame 20, and an upper frame 22 all around.

The inner screen 14, which is disposed on the indoor side of the frame body 12, is constructed by placing a rectangular panel material 32 inside the vertical frame 24, the joint frame 26, the bottom frame 28, and the top frame 30, which are assembled on all four sides. The outer screen 16, which is disposed on the outdoor side of the frame body 12, is constructed by placing a panel material 32 inside the vertical frame 34, the joint frame 36, the bottom frame 38, and the top frame 40, which are assembled on all four sides. The panel material 32 is, for example, single-pane glass or double-glazed glass.

The inner screen 14 and the outer screen 16 are formed to have dimensions that are almost identical along the left and right sides, and are capable of closing the frame body 12 when the joint frames 26, 36 are arranged side by side in the forward direction. In this embodiment, a fitting is illustrated in which, when the frame body 12 is closed, the inner screen 14 is arranged on the left side as viewed from the outside of the room, and the outer screen 16 is arranged on the right side. The frame material that constitutes the frame body 12 and the frame material provided around the inner screen 14 and the outer screen 16 are extruded shapes of metals (including alloys) including aluminum, etc., or resin, and are configured to have a nearly uniform cross section along the entire length.

Figure 3 is an enlarged cross-sectional view of the vertical frame 18 of the fitting 10 and the vertical frame 24 of the inner sash 14. Figure 4 is an exploded perspective view of the vertical frame 18, lock receiving part (functional part) 44, and sealing material 46 of the fitting 10.

The vertical frame 18 is slightly longer in the projection direction and has a symmetrical shape in the projection direction, allowing it to be used in the opposite direction. The vertical frame 18 has indoor and outdoor projection walls 18a, an outer peripheral projection wall 18b, and an intermediate projection wall 18c, which form a rectangular hollow portion 18d. Groove forming portions 41 are provided on both ends in the projection direction on the inner peripheral side of the vertical frame 18. A relative recess 18e is formed between the two groove forming portions 41.

The groove forming portion 41 has opposing groove walls 42a, between which a groove 42 is formed that opens to the inner circumference side. In the description of the groove 42 and its surroundings, the outer circumference side is also called the groove back side, and the inner circumference side is also called the opening side. In addition, the groove 42 on the indoor side is also called groove 42A, and the groove 42 on the outdoor side is also called groove 42B, as necessary. In this embodiment, the groove 42 has a depth and a projection width that allow a thin lock receiving part 44 (see Figure 4) to be installed, and is slightly long in the projection direction. The distance between the pair of opposing groove walls 42a is about 1/4 of the projection width of the vertical frame 18. The depth of the groove 42 is slightly shallower than the projection width of the hollow portion 18d.

The pair of groove walls 42a forming groove 42A on the indoor side and the pair of groove walls 42a forming groove 42B on the outdoor side protrude from the visible wall 18a to the inner periphery side. The intermediate visible wall 18c forms the bottom surface of each groove 42. The groove walls 42a have engagement protrusions 42c that protrude in a direction approaching each other from both sides in the visible direction of the opening 42b, and auxiliary protrusions 42d that protrude in a direction approaching each other from a slightly deeper side of the groove than the opening 42b. The engagement protrusions 42c are small protrusions, and the tip of the groove on the deep side is in an arc shape. Although the engagement protrusions 42c are small, they form the inner periphery side visible surface of the vertical frame 18. The auxiliary protrusions 42d are approximately rectangular and are slightly toward the opening side from the middle of the visible direction of the groove walls 42a. Although the auxiliary protrusions 42d are small protrusions, they are slightly longer than the engagement protrusions 42c.

As shown in Figures 1 and 3, the vertical frame 24 has a front wall 24a at both ends in the front direction, and two front walls 24b, 24c provided between them. Each front wall 24a protrudes from the front wall 24b on the inner circumference side to hold the panel material 32. Each front wall 24a protrudes from the front wall 24c on the outer circumference side, and each end is provided with a pocket 24d that opens to the opposite side. A groove forming part 41 on the indoor side is fitted between a pair of pockets 24d. This structure in which the groove forming part 41 fits between the pockets 24d has excellent wind pressure resistance. A seal 48 is attached to each pocket 24d. Each seal 48 has a corner 48a that elastically abuts against the groove wall 42a. A lock part 50 is provided between the front wall 24c and the pocket 24d on the vertical frame 24. The lock part 50 is set at the same height as the lock receiving part 44, and a part of the lock part 50 engages with the lock receiving part 44 by a specified operation, thereby locking the inner screen 14 in the closed position.

As shown in FIG. 4, the groove walls 42a are cut out at the upper and lower ends of the vertical frame 18, and the lower frame 20 and upper frame 22 are connected to these portions by screws 52. A blocking material 46 that blocks the groove 42B fits into the groove 42B over the entire length in the longitudinal direction. A lock receiving part 44 is fixed to a predetermined height in the groove 42A by screws 52. Blocking material 46 that blocks the groove 42B fits into the groove 42A except where the lock receiving part 44 is installed, that is, above and below the lock receiving part 44.

Figure 5 is an exploded cross-sectional view of the vertical frame 18 and the blocking material 46. The blocking material 46 is a resin elastic material such as rubber or silicone rubber, and has a uniform cross section along its entire length. The blocking material 46 is used by cutting a long material to an appropriate length. The blocking material 46 has elasticity that allows it to bend moderately easily when fitting into the groove 42, and moderate strength that allows it to stably block the groove 42 after fitting.

The plugging material 46 will be described with reference to Figures 3 and 5. The plugging material 46 is generally triangular and convex toward the back of the groove. In this embodiment, the plugging material 46 is generally equilateral triangular with the sides being equal in length. The plugging material 46 has a lid 46a that forms a visible wall on the opening side, and a pair of oblique sides (sides) 46c that protrude obliquely from both ends of the lid 46a and connect in an arc shape at the apex 46b on the back side of the groove, and the lid 46a and the pair of oblique sides 46c form a hollow 46d. Each oblique side 46c is convex toward the hollow 46d side and gently curves to be concave on the opposite side. The thickness of the lid 46a and the oblique side 46c are approximately equal, and the hollow 46d is generally triangular. The lid 46a is flat, but a fold 46e is formed in the center of the back side of the groove. The fold 46e is a shallow groove extending in the longitudinal direction.

Small recesses 46f are formed on the opening sides of both ends of the cover portion 46a in the projection direction, and engagement portions 46g are formed on the groove inner side of the recesses 46f, which are relatively convex. In other words, the pair of oblique sides 46c each protrude obliquely from the pair of engagement portions 46g. The projection dimension of the cover portion 46a between the pair of recesses 46f is slightly larger than the projection dimension of the opening 42b between the pair of engagement protrusions 42c. The projection dimensions of the recesses 46f and the engagement protrusions 42c are approximately equal. The projection directions of the engagement portions 46g and the engagement protrusions 42c are opposite, and their projection lengths are approximately equal.

Figure 6 is a cross-sectional view showing how the plugging material 46 is fitted into the groove 42. The plugging material 46 is fitted into the groove 42 by inserting the top 46b from the opening 42b toward the back of the groove and pushing it in from the opening side with a hand or a tool. In actual construction, it is recommended that one end of the plugging material 46 is fitted into the groove 42, and then further fitted toward the other end.

When the plugging material 46 is fitted, the vicinity of the engaging portion 46g in each oblique side portion 46c first comes into contact with the tip of the engaging protrusion 42c, and then the plugging material 46 elastically deforms according to the amount of pushing. The oblique side portion 46c is curved and convex toward the hollow portion 46d, so it is easily subjected to force from the engaging protrusion 42c, and is relatively pushed by the engaging protrusion 42c to approach each other. In the plugging material 46 of this embodiment, the portion that first comes into contact with the engaging protrusion 42c is at an angle of approximately 45 degrees to the prospective direction and the visible direction, so it is easily subjected to force, and then the pair of engaging portions 46g are smoothly guided to approach each other. The pair of oblique side portions 46c elastically deform so that the angle they make with each other becomes smaller based on the apex 46b, but since the apex 46b is arc-shaped, it naturally deforms into a similar shape so that the overall arc diameter becomes somewhat smaller, and there is no local excessive compression or excessive stretching. In addition, the oblique side portion 46c has a curved shape that is convex toward the hollow portion 46d, so that the arc angle of the apex 46b can be secured to be large. The arc angle of the oblique side portion 46c is, for example, about 120 degrees before elastic deformation. Furthermore, because the oblique side portion 46c has a curved shape, it becomes correspondingly longer and is more susceptible to elastic deformation.

The plugging material 46 is inserted into the groove 42 mainly by pressing the lid portion 46a. Then, the pair of engagement portions 46g are elastically displaced so as to approach each other, causing the lid portion 46a to bend elastically into a convex L-shape toward the back of the groove. At this time, the lid portion 46a is easily bent and fitted into the groove 42 because a fold 46e is formed in the center. In addition, the plugging material 46 has a hollow structure and is easily elastically deformed.

When the engaging portion 46g is pushed in until it passes through the engaging protrusion 42c, the external force acting on the lid portion 46a, the top portion 46b, and the oblique side portion 46c is eliminated, and the lid portion 46 returns to its original shape and is correctly positioned within the groove 42. This restoration is performed by the elastic force of the sealing material 46, and the worker can recognize the timing of the end of pushing by visual inspection and the feel transmitted to the hand. The fold 46e is preferably formed on the inner side surface of the groove of the lid portion 46a, as it is not visible from the outside, but may be provided on the opening side surface depending on the design conditions.

Return to Figure 3. The engagement protrusion 42c fits into the recess 46f of the plugging material 46 placed in the groove 42. The tip of the engagement protrusion 42c elastically butts slightly against both end faces of the lid 46a in the projection direction, providing a watertight effect and preventing downward slippage caused mainly by gravity. The lid 46a forms the same projection surface as the engagement protrusions 42c on both sides, which is suitable from a design perspective, and does not protrude to the inner periphery, so there is no interference with other parts such as anti-dislodgement parts and pulling pieces. Note that the lid 46a only needs to substantially block the opening 42b of the groove 42, and in practice it may be positioned slightly further back in the groove within the range where it abuts against the tip of the engagement protrusion 42c.

The pair of engagement parts 46g are each disposed between the engagement protrusion 42c and the auxiliary protrusion 42d, and engage with the engagement protrusion 42c from the back side of the groove to prevent the plugging material 46 from slipping out. The engagement parts 46g are in elastic contact with the groove wall 42a and the engagement protrusion 42c, which further improves the water-stopping effect. The oblique side part 46c is in light contact with the corner of the auxiliary protrusion 42d. This prevents the plugging material 46 from fitting too far into the back side of the groove.

Between the oblique side portion 46c and the auxiliary protrusion 42d, there may be a small gap that can substantially restrict the displacement of the blocking material 46. A narrow gap is formed between the intermediate projection wall 18c that forms the bottom surface of the groove 42 and the top portion 46b. When the blocking material 46 is pushed in, the oblique side portion 46c abuts against the corner of the auxiliary protrusion 42d at an angle, so that it may slip while being elastically deformed. Therefore, the blocking material 46 may be displaced somewhat toward the depth of the groove, but the top portion 46b abuts against the intermediate projection wall 18c as a stopper to limit further displacement. In addition, when the pushing force on the blocking material 46 is released, the pair of oblique side portions 46c spread in a direction away from each other due to the elastic force, and the blocking material 46 returns to its original position and shape. In addition, the auxiliary protrusion 42d protrudes more than the engaging protrusion 42c, and the engaging portion 46g does not displace beyond the auxiliary protrusion 42d.

The plugging material 46 has a generally triangular shape that is convex toward the back of the groove, and the apex 46b is inserted deep enough into the groove 42. Therefore, even if an unbalanced load acts on the plugging material 46 and it temporarily rotates due to a clockwise or counterclockwise rotational force in FIG. 3, the oblique side 46c abuts against the visible surface of the auxiliary protrusion 42d to restrict rotation, and it returns to its original position and shape after the unbalanced load is released.

So far, we have described the vertical frame 18 on the left side when viewed from outside the room and the blocking material 46 attached to the vertical frame 18 with reference to Figures 3 to 6, but as the right side (see Figure 1) is rotationally symmetrical, a detailed description will be omitted.

The sealing material 46 of the fitting 10 constructed in this manner is made of a resin elastic material and has a fold 46e formed on the visible surface of the lid 46a, so that it is easy to bend when pushed into the groove 42 and easy to install. The sealing material 46 is made of a resin elastic material, and elastically abuts against the opening 42b or its surrounding area, providing dust protection, rattling prevention, and slippage prevention for the groove 42, and also providing a certain degree of waterproofing. The sealing material 46 is basically easy to install in the groove 42, as no other fixing means such as screws or adhesives are required. The sealing material 46 has an engagement portion 46g that engages with the engagement protrusion 42c from the back side of the groove, and prevents it from coming out of the groove 42. The engagement portion 46g is a part of the sealing material 46 and is made of a resin elastic material, which is more suitable for snap-type engagement than metal materials. The sealing material 46 is made of resin, which provides a better surface texture than metal materials, and basically does not need to be covered with a decorative sheet.

We will now explain modified examples of this embodiment. In each of the following modified examples, the same components as in the above embodiment will be given the same reference numerals and detailed explanations will be omitted.

Figure 7 is a cross-sectional view showing the state in which the plugging material 46A according to the first modified example is fitted into the groove 42. The plugging material 46A has a pair of slightly longer oblique sides 46c, and the top 46b abuts against the intermediate visible wall 18c at the back of the groove, which corresponds to the bottom of the groove 42. This configuration makes the plugging material 46A more stable within the groove 42.

Figure 8 is a cross-sectional view showing the state in which the plugging material 46B according to the second modified example is fitted into the groove 42. The plugging material 46B does not have parts corresponding to the top 46b and the oblique side 46c of the plugging material 46, and a pair of engagement parts 46h engage with the engagement protrusion 42c. The engagement part 46h is located at a position corresponding to the engagement part 46g, but is slightly thick in the find direction and is stable by abutting both the expected surfaces of the engagement protrusion 42c and the auxiliary protrusion 42d. Since the engagement part 46g abuts the expected surface of the auxiliary protrusion 42d, such a plugging material 46B is appropriately suppressed from displacing toward the outer periphery, and since the cross-sectional area is smaller than that of the plugging materials 46 and 46A, material costs can be reduced. The engagement protrusion 46h has an inclined surface on the side facing the groove wall 42a and a shape that is slightly narrower toward the back of the groove, making it easy to insert into the groove 42.

Figure 9 is a partially enlarged cross-sectional view of a fitting 10A according to a first modified example to which a sealing material 46 is applied. Although an overall view is omitted, the fitting 10A has four sliding shoji screens and a frame body supporting them, and Figure 9 shows the butt joint of the two central shoji screens 54, 56. In Figure 9, an attachment 59 is attached to the butt joint surface of the butt frame 58 of the left shoji screen 54. The attachment 59 has a pair of groove walls 42a similar to the vertical frame 18 described above, with a groove 42 formed between them. Although not shown, a lock receiving part 44 (see Figure 4) is provided in the groove 42 of the butt frame 58, and sealing material 46 is provided in other places.

In Figure 9, the butt frame 60 of the right-side shoji 56 has a structure similar to the vertical frame 24 (see Figure 3) described above, and is provided with a front wall 24a, front walls 24b and 24c, and a pocket 24d, with a groove forming portion 41 on the interior side fitting between a pair of pockets 24d. A seal 48 is attached to each pocket 24d. A lock part 50 is provided on the butt frame 60 between the front wall 24c and the pocket 24d. Note that the state in which the attachment 59 and the blocking material 46 are removed from the butt frame 58 and the state in which the seal 48 and lock part 50 are removed from the butt frame 60 are essentially the same structure.

In this way, the plugging material 46 can be applied not only to frame materials but also to stile materials. As described above, the grooves 42 formed in the frame materials have the outer periphery side at the back of the groove and the inner periphery side at the opening, but the grooves 42 formed in the stile materials have the inner periphery side at the back of the groove and the outer periphery side at the opening.

Figure 10 is a partially enlarged cross-sectional view of the fitting 10B according to the second modified example to which the blocking material 46 is applied. The fitting 10B supports the front door 62 with a frame body 64, and a groove 42 that opens to the inner periphery is formed on the inner periphery of the vertical frame 66. The outer peripheral side of the inner periphery of the vertical frame 66 forms the bottom wall 66a of the groove 42. A screw 70 (such as an anchor screw) is driven into the bottom wall 66a to fasten the vertical frame 66 to the main body 68. The head 70a of the screw 70 is exposed in the groove 42, but the groove 42 is blocked by the blocking material 46 and is therefore not visible from the outside. In addition, the cover 46a of the blocking material 46 and the inner peripheral side of the inner periphery of the vertical frame 66 form the same surface, making it possible to smooth the surface around the frame. As described above, the top 46b of the blocking material 46 is slightly separated from the bottom surface of the groove 42, so it does not interfere with the head 70a.

The groove 42 for mounting the blocking material 46 may be formed in the lower frame 20, the upper frame 22, the lower stiles 28, 38, or the upper stiles 30, 40. When the groove 42 is formed in the upper frame 22 or the upper stiles 30, 40, a part (functional part) for preventing the frame material from coming loose from the stile may be provided in part of the groove 42, and the blocking material 46 may be mounted in other places.

The present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit of the present invention.

The fixture of the present invention is a fixture comprising a shaped member that forms part of a frame or a shoji screen and has a groove formed on its visible surface in the longitudinal direction, and a sealing member that fits into the groove to seal it, the shaped member having engagement protrusions that protrude in directions approaching each other from both sides in the visible direction of the opening of the groove, the sealing member being an elastic material, and having a lid that seals the opening, a fold line formed in the longitudinal direction on the visible surface of the lid member, and an engagement portion that engages with the engagement protrusions from the back side of the groove.

This type of fitting's sealing material is made of elastic resin and has folds formed on the visible surface of the lid, so it bends easily when pushed into the groove and is easy to install.

The fittings of the present invention are suitable from a design perspective if the exposed side of the sealing material is on the same side as the visible side of the profile or on the inner side of the groove, and since it does not protrude to the inner circumference, it does not interfere with other parts.

In the fittings of the present invention, the sealing material may abut against the visible surface of the groove at the rear side. This makes the sealing material even more stable.

In the fitting of the present invention, the sealing material may have a pair of side portions that protrude from the pair of engagement portions and connect at the back side of the groove, and a hollow portion may be formed by the pair of side portions and the lid portion. If there is such a hollow portion, the sealing material is easily deformed when it is fitted into the groove, making the work easier.

The pair of side portions of the fixture according to the present invention may be curved so as to be convex toward the hollow portion. This makes it easier to fit the sealing material into the groove.

In the fitting of the present invention, the pair of sides may each protrude obliquely from the engaging portion and connect in an arc shape at the back of the groove. This allows the top where the sides connect to each other to deform smoothly.

In the fitting of the present invention, the shaped member constitutes the vertical frame of the frame body, the groove is formed on the inner peripheral side visible surface and a functional part is installed in a part of the groove, and the blocking material may be provided in a place other than the installation location of the functional part in the groove.

In the fitting of the present invention, the frame body supports a sliding window, and the groove may be formed on the inner peripheral visible surface.

In the fittings of the present invention, auxiliary protrusions are formed in the groove that protrude toward each other from the groove walls on both sides in the projection direction, and the pair of engagement parts may be located between the engagement parts and the auxiliary protrusions. Such auxiliary protrusions prevent the sealing material from shifting toward the back of the groove.
