Description

[Detailed Description of the Invention] [Object of the Invention] This invention is for a sliding door, that is, for a sliding door of a kind of fitting that is fitted in a groove of a sill and slid to open and close. It's about slippers,
An object of the present invention is to provide a sliding material for a sliding door having a novel structure which is excellent in terms of attachment to the lower surface of the sliding door, compatibility with a threshold groove, and the like.

[Prior Art] Among traditional Japanese fittings, sliding doors such as shoji and sliding doors are used by being fitted into the groove of the sill, and sliding along the groove opens and closes. Large friction tends to occur between the lower surface of the sliding door and the groove bottom of the threshold. Therefore, various measures have been conventionally taken to smoothly open and close the sliding door.

As one example of them, a tack-shaped one is formed from a hard plastic such as Teflon with a smooth surface, and the tip of the tack is driven into the lower surface of the sliding door and fixed, or the actual opening 53-
As in the device published in the back of No. 145348, by attaching a door slide piece with a fluororesin film formed on an elastic mount with adhesive, and using it to adhere to the bottom of the fitting, the lower surface of the sliding door There is one in which a flat head of a somewhat protruding stud or a door sliding piece is brought into contact with a groove bottom of a sill to reduce friction between a sliding door and the sill.

However, such plastic studs or door slides, although smooth, are much harder than wooden sills, and as the sliding doors are repeatedly opened and closed, the groove bottoms of the sill are greatly worn down. There was a problem of being lost.

If the stud wears out, you only have to replace the stud each time, but if the sill wears down as described above, it is not possible to replace the sill, and it is easy to use other means. Since it could not be repaired, it was very inconvenient for the parties.

As another example, a plastic tape, which has a number of ordinances of triangular cross section formed on the surface, is attached to the entire groove bottom of the sill, and the sliding door slides on the smooth tape surface. Things are also well known.

However, when this long tape is attached to the entire surface of the groove bottom of the sill for sliding doors, slack is generated in the middle of the tape during repeated opening and closing of the sliding door and receiving the heat of the sun. , If you still open and close without correcting the slack, you will eventually cut and break from the slack part, and the damaged part will become a step even if it is a little, and it will hinder smooth sliding. There was a problem of being lost.

Moreover, if you try to reattach the tape after falling into such a situation, not only is the tape itself difficult to remove,
The adhesive remains on the entire bottom of the sill and cannot be easily removed.As a result, unevenness is created in the sill groove, and even if a new tape is tentatively placed, the slippage will be smooth due to the unevenness. Therefore, there is a troublesome problem that extra labor such as having to re-cut the groove of the threshold a little is required.

The sliding material for a sliding door of the present invention has been developed and completed to cope with the above situation, and the details of the configuration will be shown below.

[Structure of the Invention] As can be understood from each of the embodiments shown in the drawings, the sliding member for a sliding door of the present invention basically has the following structure.

That is, the hardness is about the same as or slightly softer than the sill material, and the width is such that it fits within the sill groove and the other two sides are not orthogonal to the two sides arranged in parallel with the sill groove. A thin piece formed in a quadrilateral or arrow feather shape is provided with a hole penetrating from one surface to the other surface thereof, and the hole is filled with a solid material having good lubricity and one surface of the thin piece is formed. Is a sliding member for a sliding door formed by forming an adhesive layer on the lower surface of the sliding door.

As the thin piece, it is limited to a material having a hardness that is about the same as or slightly softer than the threshold material, for example,
It is most ideal to use wood (paulownia, phoenix, rice cypress, etc.) as well as joinery, but other restrictions have been set so that the hardness is about the same as or slightly softer than the sill material. It is possible to use thin flakes made of plastic of the nature or paper materials of which hardness is similarly regulated. In that sense, although the hardness is regulated, it can be said that the material is not particularly limited.

As the means for combining the lubricant with the thin pieces, in addition to those shown in the examples described later, those in which grooves or recesses are appropriately formed as the cross section of the surface opposite to the adhesive layer forming surface of the thin pieces should be adopted. , While the whole material is impregnated with a lubricant, the groove and the recess are filled with a lubricant so that the lubricant naturally appears on the surface of the flakes as the flakes wear. Any structure having the above structure can be adopted in the present invention.

The shape and size of the flakes must have a width that fits within the sill groove, and also in terms of their thickness, not only a mere sliding material, but also a member for correcting the erection of a fitting and a sill. Depending on various factors such as whether or not to assume the service life as a sliding material, it is sufficient to set the thickness to an appropriate value.
If the thickness is about m, the intended purpose can be achieved.

As a solid lubricant to be combined into flakes, wax is
Since it is a cheap material that can be easily filled or impregnated, the most general one can be said, but other solid materials with good lubricity (materials that solidify at room temperature) are also available. It goes without saying that any lubricant that can be filled or impregnated can be used.

Hereinafter, the configuration of the present invention will be described more specifically based on the embodiments shown in the drawings.

[Example] This example is an example of a specific combination of the thin piece 1 and the lubricant 2.

That is, as can be clearly understood from the perspective view of FIG.
A filling hole penetrating from one surface to the other surface of the thin piece 1 having a hardness that is about the same as or slightly softer than the sill material.
11 is formed, and the hole 11 is filled with a solid lubricant 2 having a good lubricating property, such as wax, to form a sliding door sliding member.

The hole 11 formed in the thin piece 1 has a diameter of about 10 mm based on the width value of the thin piece 1 which is determined by the width of the sill groove S1 (about 20 mm for ordinary household shoji and sliding doors). It can be said to be of a general size. Further, although the thin piece 1 is shown as having a structure in which the lubricant 2 having two circular cross sections is housed in the embodiment, the cross section of the lubricant 2 does not necessarily have to be circular, and for example, an elliptical shape or Needless to say, the shape may be a quadrangle or another shape, and the number of formation is not limited to two, and one or three or more may be formed as appropriate. It is possible to do so.

However, considering the strength of the sliding material itself, the shape of the curve should be as simple as possible so that the stress generated in the thin piece 1 against the force applied from the outside during use will not concentrate at a specific location around the filling hole 11. Is desirable.

It should be noted that FIG. 5 shows one step of manufacturing the sliding member of this example. That is, first, a square bar K having a constant width equal to the width W shown in FIG. 2 is prepared, and a plurality of hollow holes K1 penetrating from the front surface to the rear surface thereof are formed at predetermined intervals, and then these holes are formed.
The melted and liquid lubricant is poured into K1 and solidified, and then cut into a desired thickness of, for example, 1 to 2 mm in a plane orthogonal to the penetrating direction of this hole K1 and long. Form flakes. Then, if necessary, an adhesive is applied to the back surface of the long thin piece to form an adhesive layer 3, and the adhesive layer 3 is covered with release paper 4 or the like, and then cut into short pieces at desired intervals. The desired slipping agent can be produced by going through the process. Of course, this manufacturing method is one example, and other
For example, it goes without saying that the thin side 1 having a predetermined thickness in which the filling hole 11 is formed in advance can be prepared, and then the lubricant 2 can be filled later.

It is assumed that the thin piece 1 is formed in a parallelogram shape or a quiver shape so that the other two sides are not orthogonal to the two sides arranged in parallel with the groove S1 of the sill S.

More specifically, among the four sides of the parallelogram forming the outer shape of the thin side 1, two sides arranged in parallel with the groove S1 of the sill S are
The other two sides are configured to be inclined at an angle θ with respect to 90 °, and it is most convenient to form this angle θ at, for example, about 30 °.

The width W (height of the parallelogram) and the length L (the length of the bottom of the parallelogram) of the thin piece 1 are not particularly limited, but the width W
As shown in FIG. 3, it is desirable that the width L be approximately the same as or slightly narrower than the width of the lower surface T1 of the sliding door T, and the length L be any length longer than the width W.

In addition, the shape of the thin piece 1 is not limited to a parallelogram, and for example, the shape of the arrow feather shape in which the shape of the two sides on the side of the sill S obliquely arranged with respect to the groove S1 is a V shape. It can also be formed. In the illustrated examples of FIGS. 1 to 4, all are shown as parallelogram-shaped ones, and not particularly arrowhead-shaped ones.

[Operation] The sliding member for a sliding door of the present invention having the above-mentioned structure is used by the following method.

That is, as can be understood from FIG. 3 which is a perspective view showing a use state, the sliding member for sliding door of the present invention has a lower surface of the sliding door T such as shoji or sliding doors (that is, as shown in FIG. 4, When the sliding door T is fitted into the sill S, it is used by adhering to the surface T1 of the sill S which comes into contact with the groove bottom S1.
The release paper 4, which is a protective layer of the adhesive layer 3 formed on one surface of the one side, is peeled off, the adhesive layer 3 is directed toward the lower surface T1 side of the sliding door T, and its posture is set so as to be parallel to the lower surface side edge. Carefully press it firmly and fix it with adhesive.

Then, when the sliding door T is fitted in the same manner as fittings, the lower surface to which the sliding material is attached fits within the groove S1 and the sliding door is fully loaded on the sliding material, so that the sliding material is always pressed down. Therefore, there is no possibility that the sliding material will be peeled off from the lower surface of the sliding door T, and only the sliding material slides in the groove S1 while being in contact with the groove S1 of the sill S.

If the sliding material is made of wood and manufactured by the manufacturing method as shown in FIG. 5, some warping may occur at the manufacturing stage. In such a case, the warped concave surface If the adhesive layer 3 is formed (or the adhesive is applied) on the side and the adhesive is fixed by opening it, the whole adhesive surface can be pressed by pressing around the center rather than simply adhering a flat object. Easily contacts the lower surface T1 of the sliding door T,
It can be made more advantageous in sticking work.

When the sliding door T fitted in this way is opened and closed, the surface of the sliding member is replaced by the surface of the sliding member S instead of the lower surface T1 of the sliding door T.
Of the lubricant 2 applied to the bottom surface of the sill groove S1 by contacting the groove bottom S1 of the sill groove S1 and the lubricant layer applied to the sill groove S1. The sliding door T can be moved without resistance.

In addition, as shown in the plan view showing the relationship between the threshold S and the sliding door T in FIG. 4, the sliding member is the bottom surface of one fitting T.
Instead of sticking one sheet near each end of T1, you may increase the number of sheets to be used depending on the weight and width of the sliding door T. It is also possible to attach two or more sheets to the same place by appropriately stacking them.

[Effect] Since the sliding door sliding member of the present invention having the above-described structure is formed by combining the lubricant 2 with the thin piece 1 having the hardness that is about the same as or slightly softer than the sill material. During operation of opening and closing the sliding door T, the thin piece 1 is gradually worn away, and accordingly, the lubricant 2 is constantly sill groove S1.
It is exposed on the side and forms a new lubricant layer on the bottom of the groove to help smooth sliding of the sliding door T in the groove S1, and to the extent that the groove S1 of the sill S is scraped away. Compared to the case of using a tack made of hard plastic, it is much smaller, and the resistance from the uneven part generated in the groove S1 is also reduced, which ensures a smoother movement as a whole. .

In particular, in the case where the filling hole 11 of the thin piece 1 is filled with a solid lubricant 2 such as wax as shown in the embodiment, as the thin piece 1 wears, the lubricant 2 directly contacts the bottom surface of the threshold groove S1. Since it is touched and rubbed against, it has a characteristic that the action of reducing the frictional resistance appears extremely effectively.

Furthermore, since the thin piece 1 is not used as a long tape attached to the entire surface of the groove bottom S1, it will not be loosened or cut during use, and it will be worn out and will not cause any problems. Outside that can be used without, sliding door T
It is used by sticking it to only a part of the lower surface T1 of T. Therefore, it can be easily peeled off when it is necessary to peel it off for some reason, and the amount of remaining adhesive is extremely small. Since it can be easily removed, it is possible to realize a smooth surface without unevenness even after the sliding material is replaced with a new sliding material.

In addition, in the case where the shape of the thin piece 1 is a parallelogram or arrowhead shape in which the other two sides are not orthogonal to the two sides arranged in parallel to the groove S1 of the sill S, the other two sides are Since the sliding door T is arranged obliquely with respect to the groove, when the sliding door T is fitted into the groove bottom S1 and slid, the two sides obliquely arranged with respect to the groove S1 serve as blades, and the groove bottom The dust and debris accumulated in S1 are pushed to one corner of the groove S1 to exert a cleaning effect, which keeps the contact surface between the sliding member and the groove bottom S1 always clean, so that the sliding door T slides. The state can always be maintained in good condition.

As mentioned above, the sliding material for a sliding door of the present invention has excellent features that have never existed before in maintaining the sliding of the sliding door in a good condition. It is also extremely excellent in compatibility with the threshold groove, and furthermore, it has a relatively simple structure, is easy to manufacture, can be provided at low cost, and can be used as easily as that. It is a thing.
