JPH10196234A - Lower rail device of heat insulating paper-sliding door - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce a depth width of the whole lower rail by constituting a lower rail main body by connecting an inside member and an outside member to each other through heat insulating connecting materials, and constituting so as to arrange a heat insulating reinforcing material where the engaging groove one end of a sash roller arranged on the under side of the heat insulating connecting materials of the lower rail main body is installed on the inside member and the other one end is installed on the outside member. SOLUTION: An inside member 1a composed of an aluminum extruded section and similarly an outside member 1b, are connected to each other through heat insulating connecting materials 2 and 2, and an engaging groove 4 of a glass panel 3 is arranged just above the heat insulating connecting materials 2 of a lower rail main body 1, and an engaging groove 6 of a sash roller 5 is arranged just under it. Sandwiching inserting grooves 10 and 10' of an under surface side opening are also formed on an inside surface on the lower side of part pieces 9 and 9' of the inside member 1a and the outside member 1b, and locking part pieces 11 and 11' are sandwiched and inserted in the sandwiching and inserting grooves 10 and 10', and heat insulating reinforcing materials 13 are arranged between members 1a and 1b. Therefore, a lower rail device by which a depth dimension can be reduced more than a conventional example and which has no hindrance to strength by using a reinforcing member, can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated sliding door sliding door lower frame device having an extruded aluminum profile as a main member.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Patent Application Laid-Open No. 8-135311, an inner member and an outer member are separated from each other via a heat insulating connecting material (generally made of synthetic resin). It has a combined configuration.

[0003]

The lower frame of the sliding door sliding door is provided with an engaging groove which is opened at a lower portion for installing a door roller, and the upper wall portion constituting the engaging groove is formed between the inner and outer members. If it is made of a separate heat insulating connecting material, it will cause a problem in strength such as load resistance and the like. Therefore, in the conventional example, the engagement groove portion is formed only of the outer member so as to avoid the problem of strength. I have to.

Therefore, in the prior art, a part for assembling the connecting material must be specially formed in order to interpose the heat insulating connecting material between the inner and outer members. ) Has the disadvantage of increasing the expected width, and of course,
Since the material is required, the cost is high.

The present invention has been made by focusing on such a drawback of the conventional example.

[0006]

Means for Solving the Problems An inner member and an outer member made of extruded aluminum members are connected to each other via a heat insulating connecting material to form a lower frame main body. One end of the engagement groove of the door roller provided on the lower side is attached to the inner member, and the other end is attached to the outer member.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view showing one embodiment of a lower frame device of an insulated sliding door shoji according to the present invention.

In the drawing, A is a lower frame, and the lower frame A is formed by connecting an inner member 1a made of extruded aluminum material and an outer member 1b to each other through heat insulating connecting members 2 and 2 to each other. And the engagement groove 4 of the glass door 3 is provided directly above the heat insulating material 2 and the engagement groove 6 of the door roller 5 is provided immediately below.

The heat-insulating connecting material 2 is made of a synthetic resin (a nylon resin in the embodiment), and the inner and outer members 1a, 1
b, a pair of upper and lower sandwiching grooves 7 formed in an intermediate portion closer to the upper side of FIG.
a, 7'a, 7b, 7'b, and the inner and outer members 1
a and 1b are assembled together to form the lower frame main body 1.

On the lower inner surface of the pieces 9, 9 'of the inner and outer members 1a, 1b constituting the engaging groove 6, insertion grooves 10, 10' are formed. Entry groove 10, 1
0 ', the locking pieces 11, 11' are inserted into the insertion grooves 10, 1 '.
0 'and the heat-insulating reinforcing material 13
It is arranged at an appropriate place between a and 1b.

The reinforcing member 13 is formed by connecting the locking pieces 11, 11 on both sides of a central piece 13 a provided with a concave portion 14 with which a door guide rail 31 provided on a lower frame 30 is engaged. The device is provided with a suitable number of pieces as a piece at a position deviating from the mounting position of the door roller 5 to be mounted in the engagement groove 6, and is made of inexpensive vinyl chloride resin.

[0012]

The present invention has the configuration described above,
It is suitable for installation on a so-called heat-insulating sliding door with a heat insulating material between the inner and outer members. Can be provided, and the use of the reinforcing member can provide a lower frame device that does not hinder the strength.
