Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a steadying device for a sliding door that closes shutters, etc. by abutting them against each other.

<Prior Art> For example, Utility Model Publication No. 56-1910 is known as a sliding door steady rest device that automatically operates when a sliding door such as a rain door is closed. FIG. 6 shows this known technique, in which a hollow elastic member 62 is provided in a shutter 61, and a side portion 62a of the elastic member 62 is formed of an elastic member softer than a head portion 62b and a base portion 62c. The head 62b of the elastic member 62 that faces when closed.
The side portions 62 are brought into pressure contact with each other.
a protrudes and deforms laterally, and the side portion 62a comes into pressure contact with the inner surface 63a of the shutter rail 63.

However, the above conventional technology has the following drawbacks. That is, first, the elastic member 62 is hollow, and has a side portion 62a and a head portion 62 on both sides thereof.
(b) Since the base part 62c and the base part 62c have different hardnesses and must be manufactured integrally, manufacturing is very troublesome and difficult. And the adjacent shutter 61,
Elastic members 62, 62 respectively provided in 61
When the shutters 61, 61 are closed, the heads 62b, 6 simply
2b, and there is a slight gap between the shutter 61 and the inner surface 63a of the shutter rail 63, so the center lines CL ₁ and CL ₂ often do not match. . If the center lines CL ₁ and CL ₂ shift in this way,
An imbalance occurs in the force that is generated when the heads 62b are pressed against each other and deforms the side portions 62a, and as a result, 1
One side 62a of the two elastic members 62 is deformed more protrudingly than the other, and as a result, only one side slips to one side, resulting in significant wear and tear on the elastic members 62.
It becomes impossible to prevent rattling. Furthermore, since the elastic member 62 is hollow and has a large degree of freedom, the support member 64 is provided to regulate the degree of deformation, resulting in a complicated structure.

<Problems to be solved by the invention> The invention aims to solve the above-mentioned drawbacks of the prior art.The purpose of the invention is to provide a simple structure, easy manufacture, reliable steadying of the sliding door, and ,
To provide a steady rest device whose steady rest function is not impaired even during long-term use.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a projecting member at the upper end of one of the sliding doors, which are installed adjacently butt-to-bottom between the upper and lower rails. , a recessed member having more elasticity than the protruding member is provided at the upper end of the other adjacent sliding door, and the recessed member is fitted into the recessed member when both sliding doors are closed. The main feature is that the upper rail is deformed so as to protrude outward and come into pressure contact with the inner surface of the upper rail.

<Function> In the present invention, the protruding member provided on one side of the adjacent sliding door and the recessed member provided on the other side of the sliding door need only be configured so that the former fits into the latter. It is simple and easy to manufacture. Further, by fitting the protruding member into the recessed member, the center lines of the sliding door do not shift from each other when the sliding door is closed, and therefore, there is no imbalance in the applied forces.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

1 and 1' are shutters, 2 and 2' are steel plate face plates with appropriate ribs, 3 and 3' are steel plate upper frames, and 4 and 4' are vertical bars. There is a vertical groove part 5,
Convex strips 6 to be inserted into the vertical grooves 5 are formed on the vertical bars 4' of the other shutter 1'. 7,
Numeral 7' is a synthetic resin anti-scratch, which is attached to the vertical beams 4 and 4', respectively, to prevent them from directly rubbing against the inner surface 8a of the rail 8 and causing scratches or making metallic noises when the shutters 1 and 1' are opened and closed. It is fixed by fitting a fixing part (not shown) into the upper part. The upper rail 8 has a generally shaped cross section, and the storm shutters 1 and 1' are erected adjacently butted between the upper rail 8 and a lower rail (not shown).

It is fixed at the protruding base 9b by. Suitable materials for this protruding member 9 are metals such as aluminum or hard plastics such as DURACON (trade name), but only the protruding end portion 9a is made of the above-mentioned hard material, and the other protruding base portions 9 are made of the above-mentioned hard material.
b may be made of a different material.

Reference numeral 10 denotes a recessed member 10 provided at the upper end of the other shutter 1', which has a receiving recess 10a formed at a position corresponding to the protruding base 9a of the protruding member 9, and recessed side portions 10b on both sides thereof. 10b and screw 12
is fixed to the upper surface of the anti-scratch 7' at the recessed base 10c. 10d is the recessed side part 10b
10e is a circular notch formed at the tip (inner part) of the receiving recess 10a. The recessed member 10
Suitable materials for this include elastic materials such as rubber and soft resins such as urethane resin.
In particular, when the shutters 1, 1' are closed, the recessed side portions 10b, 10b are deformed to protrude outward (in a direction perpendicular to the closing direction) due to the fitting of the protruding end portion 9a into the receiving recess 10a, and the upper rail 8 A material that presses against the inner surface 8a of the shutter and returns to its original state when the shutters 1, 1' are released from closing is used. In addition, since the cut portions 10d and 10e are provided, the outward protruding deformation of the recessed side portions 10b and 10b is easily performed.

In the structure as described above, when both adjacent shutters 1 and 1' are completely closed, the protruding end 9a of the protruding member 9 provided on one shutter 1 side will open as shown in FIG. 2B. , the recessed member 10 provided on the other shutter 1' side is fitted into the receiving recess 10a while expanding and deforming the recessed side parts 10b, 10b. Then, as a result of the fitting, a force is applied to the recessed side portions 10b, 10b by the convex end portion 9a, so that the recessed side portions 10b, 10b are respectively deformed to protrude outward. It is strongly pressed against the inner surface 8a of the rail 8. Then, during the protrusion deformation, the recessed member 10
The gap of the notch 10d formed between the recessed side part 10b and the recessed base part 10c is completely closed, and the outward protrusion deformation of the recessed side part 10b is performed more smoothly. This ensures that the recessed side portion 10b is pressed against the inner surface 8a of the upper rail 8, and the shutters 1, 1' do not shake at all.

Then, when shutters 1 and 1' are released,
Since the force of the protruding end portion 9a ceases to act, the recessed side portions 10b, 10b return to their original shapes due to their restoring force.

FIG. 3 shows the mounting structure of the steady rest device on the door stop block side and the door pocket side of the storm door. In the illustrated example, a recessed member 101 is provided on the inside vertical surface of the door stop block 20. , a protruding member 91 provided at the upper end of the shutter 1A near the door stop block 20 is fitted, and the end of the inner plane of the door pocket 21 is fitted with the shutter 1A, 1B, 1C.
