Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention is attached to the upper edge of fittings such as screen doors that are opened and closed in window frames, etc., and is used in a direction perpendicular to the moving direction of the fittings in the window frame. The present invention relates to a steady rest for fittings that prevents runout.

(b) Conventional technology For fittings such as screen doors that are opened and closed in window frames, it is generally
As shown in the drawing, the door wheel 42 is rotatably provided at the lower edge portion, the steady rest 41 is provided at the upper edge portion, and the door wheel 42 is rotated on the lower rail 33 of the window frame. Further, the steady rest 41 engages with the upper rail 32 of the window frame to prevent the fitting 31 from moving in a direction perpendicular to the opening / closing direction (left and right direction in the drawing), and removes the wheel of the door roller 42 and the mesh door 31. Prevent.

The steady rest 41 engages with the upper rail 32 in the groove 45 as shown in FIG. In addition, the steady rest 41 is formed with a vertically elongated hole 43.
The engagement state between the groove 45 and the upper rail 32 can be made appropriate by appropriately changing the penetrating position of the mounting screw 44 in 3. That is, when the screen door 31 is fitted into the window frame, the mounting screw 44 is passed through the upper portion of the long hole 43 to shorten the distance between the steady rest 41 and the door roller 42, and thereby the upper rail 32 and the lower rail 33 are separated. The screen door 31 is set in a state where it is easy to fit in between. After fitting the fitting 31 in the window frame, the mounting screw 44 is penetrated below the long hole 43 to increase the distance between the steady rest 41 and the door roller 42 to prevent the screen door 31 from swinging in the window frame. .

However, in the steady rest 41 as shown in FIG.
The side surface of the groove portion 45 comes into contact with the side surface of the upper rail 32 to generate frictional resistance, which causes a problem that the opening / closing operation of the screen door 31 is not smoothly performed.

Therefore, as shown in FIG. 5, the engaging member 52 is rotatably supported at a fulcrum 55 provided in a part of the main body 51,
There is a steady rest 51 in which the roller 53 of the engaging member 52 is brought into contact with the upper rail. In this steady rest device 51, the engagement member 52 is brought into contact with the upper rail by the torsion coil spring 54 (direction of arrow B).
Is urged by. With this configuration, the roller 52 is always in contact with the upper rail, and the roller 53 rotates with respect to the upper rail when the screen door is opened and closed, so that the screen door can be smoothly opened and closed.

(c) Problems to be Solved by the Invention However, in the above-described conventional steady rest, as shown in FIG. 6, when the external force in the direction of the arrow C acts on the lower end of the screen door 31, the screen door 31 is lifted by frictional resistance. When only one of the edge portions is pushed up, the engaging member 52 moves in the direction of arrow A with respect to the main body 51, the upward movement of the screen door 31 cannot be restricted, and the door roller is disengaged from the lower rail. There was a problem of ringing. Further, in such a case, the screen door 31 is not attached to the window frame.
If the screen tilts significantly, the other of the upper edge portions of the screen door 31 moves largely downward, and the steady rest cannot engage with the upper rail of the window frame, and the shake of the screen door 31 cannot be regulated. . The state in which the external force acts only on one of the lower end portions of the screen door 31 as described above is likely to occur in a window portion provided at a relatively high position such as a railing, and there is a risk that the screen door will fall out of the window portion due to wheel removal of the door roller. There is.

The purpose of this invention is to smoothly open and close the screen door by engaging the roller and the groove with the upper rail, and to surely prevent the fittings from moving upward beyond a certain range in the window frame. Preventing the door roller of the fitting from derailing from the lower rail of the window, and preventing the fitting from disengaging from the upper rail when the fitting moves downward in the window frame, ensuring the runout of the fitting. It is to provide a steady rest for a fitting that can prevent the fitting from falling.

(d) Means for Solving the Problems The steady rest for appliance according to the present invention has a vertically elongated hole through which a mounting screw penetrates, and a main body attached to the upper edge of the fitting through the mounting screw. , A stopper integrally formed on the main body and having upper ends facing the horizontal surface of the upper rail on both sides of the vertical surface of the upper rail of the window frame, and vertically movable with respect to the main body, and having a peripheral surface. An engaging member having a roller that abuts a lower end of a vertical surface of the upper rail with an upper limit near a lower end position of the stopper as an upper limit, and an elastic member that biases the engaging member upward are provided. And

(e) Action In this invention, the engaging member having the roller whose peripheral surface abuts the lower end of the vertical surface of the upper rail of the window frame is movable in the vertical direction with respect to the main body. It is biased upward by an elastic member. The contact position between the peripheral surface of the roller and the lower end of the vertical surface of the upper rail is limited to the lower vicinity of the upper end position of the stopper, and the engagement member contacts the peripheral surface of the roller and the upper rail. The position moves upward within a range not exceeding the lower vicinity of the upper end position of the stopper.
The stopper is formed integrally with the main body, and its upper end faces the horizontal surface of the upper rail on both sides of the vertical surface of the upper rail.

Therefore, when the main body is attached to the upper edge of the fitting through the attaching screw so that the upper end of the stopper is sufficiently close to the horizontal surface of the upper rail of the window frame, the peripheral surface of the roller of the engaging member is changed to the upper end of the stopper. The lower end elastically contacts the lower end of the vertical surface of the upper rail, and the upper end of the stopper faces the horizontal surface of the upper rail with a gap. When an external force that lifts the fittings is applied in this state, the stoppers come into contact with the fittings due to the contact between the roller peripheral surface and the lower end of the horizontal surface of the upper rail within a range in which the magnitude of the external force does not exceed the elastic force of the elastic member. Is urged downward, the gap between the upper end of the stopper and the horizontal surface of the upper rail is maintained, and the open / closed state of the fitting is maintained smoothly.

On the other hand, when the magnitude of the upward external force acting on the fitting exceeds the elastic force of the elastic member, the fitting moves upward by the gap between the upper end of the stopper and the horizontal surface of the upper rail, and then the upper end of the stopper. Comes into contact with the horizontal surface of the upper rail, and further upward movement of the fitting is restricted. That is, when the upper end of the stopper comes into contact with the horizontal surface of the upper rail, the upward movement of the fitting with respect to the window frame is stopped, and the door roller does not fall off the lower rail at the lower end of the fitting.

Further, the abutting position between the roller peripheral surface and the lower end of the vertical surface of the upper rail is located below the upper end position of the stopper as an upper limit, so that the roller peripheral surface is perpendicular to the upper rail. The upper end of the stopper will always be located on both sides between the horizontal surface of the upper rail and the lower end of the vertical surface while it is in contact with the lower end of the surface, and the fitting will tilt vertically with respect to the window frame. Even when the stopper is engaged, the stopper is in a state of being able to contact the vertical surface of the upper rail, so that the swing of the fitting is surely regulated.

(f) Embodiment FIGS. 1 (A) and 1 (B) are a front view and a side view, respectively, of a steady rest for a fitting according to an embodiment of the present invention.

An engagement member 2 is pivotally supported on the instrument body 1. The engagement member 2 pivotally supports the roller 4. The elastic force of the elastic member 3 acts on the engaging member 2 in the arrow B direction. A stopper 6 is formed integrally with the instrument body 1. A groove portion 7 is formed in the upper portion of the stopper 6, and an elongated hole 5 is formed in the lower portion. A mounting screw penetrates the long hole 5. The upper limit of the movement of the engaging member 2 in the direction of the arrow B is the position where the upper end of the peripheral surface of the roller 4 coincides with the lower vicinity of the upper end position of the stopper 6. In the groove portion 7 of the stopper 6,
The vertical surface of the upper rail of the window frame into which the fitting such as the screen door to which the device body 1 is attached is located, and the upper end of the stopper 6 faces the horizontal surface of the upper rail on both sides of the vertical surface of the upper rail.

FIG. 2 is a side view illustrating a usage state of the steady rest device for fittings.

The device body 1 is fixed to the upper frame 23 of the screen door 22 via a mounting screw 8 penetrating the elongated hole 5 formed in the stopper 6.
By displacing the penetrating position of the mounting screw 8 in the long hole 5, the fixing position of the instrument body 1 with respect to the screen door 22 can be changed up and down. The upper end of the stopper 6 is located on both sides of the vertical surface 21b of the upper rail 21 of the window frame on the horizontal plane 21.
When the penetrating position of the mounting screw 8 in the long hole 5 is selected so as to be sufficiently close to a, the vertical surface 21 of the upper rail 21 of the window frame is selected.
b is located in the groove portion 7 of the stopper 6, and the upper end of the stopper 6 faces the horizontal surface 21 a of the upper rail 21. At this time, the peripheral surface of the roller 4 and the lower end of the vertical surface 21b of the upper rail 21 are in contact with each other below the upper end of the stopper 6.

The roller 4 is biased in the direction of arrow B by the elastic force of the elastic member 3, and the screen 22 is biased downward with respect to the window frame by this elastic force. Therefore, the stopper 6 formed integrally with the instrument main body 1 is also urged downward together with the screen door 22 by the elastic force of the elastic member 3.
Even when an external force that pushes the screen door 22 upward is applied when moving the window in the opening / closing direction in the window frame, if the magnitude of the external force is smaller than the elastic force of the elastic member 3, the upper end and the upper side of the stopper 6 are Since the rail 21 does not come into contact with the horizontal surface 21a and the gap therebetween is maintained, the opening / closing operation of the screen door 22 is smoothly performed.

On the other hand, when the magnitude of the external force that pushes up the screen door 22 exceeds the elastic force of the elastic member 3, the screen door 22 moves upward by the gap between the upper end of the stopper 6 and the horizontal surface 21a of the upper rail 21. Then, the upper end of the stopper 6 that has moved upward together with the screen door 22 has the horizontal surface 21 a of the rail 21.
Abut. This contact prevents the screen door 22 from moving further upward. For this reason, the door roller (not shown) attached to the lower edge of the screen door 22 does not fall off the lower rail of the window, and accidents such as the screen door falling can be prevented in advance.

In addition, the peripheral surface of the roller 4 and the vertical surface 21b of the upper rail 21.
The contact position with the lower end of the stopper 6 is always lower than the upper end of the stopper 6, and the upper end of the stopper 6 is higher than the lower end of the vertical surface 21b of the upper rail 21.
By engaging the groove portion 7 of the stopper 6 with the vertical surface 21b of the upper rail 21, even if the upper edge of the screen door 22 moves downward, the swing of the screen door 22 can be reliably stopped.

(g) Effect of the Invention According to this invention, the peripheral surface of the roller of the engaging member elastically contacts the lower end of the vertical surface of the upper rail of the window frame,
The stopper can be urged downward against the window frame, the upper end of the stopper does not come into contact with the horizontal surface of the upper rail even if a slight upward external force is applied to the fitting, and the roller moves upward. By rotating with respect to the rail, the opening / closing operation can be smoothly performed. On the other hand, when a large upward force is applied to the fitting, the stopper abuts on the horizontal surface of the upper rail to reliably restrict the upward movement of the fitting, and the door wheel removal and fitting Can be prevented in advance. Further, the contact position between the roller and the lower end of the vertical surface of the upper rail is always lower than the upper end position of the stopper, so that the fitting may be tilted vertically with respect to the window frame. Even if one of the upper edges moves downward, there is an advantage that the swing of the fitting can be reliably stopped by the contact between the stopper and the vertical surface of the upper rail.
