Description

  The present invention relates to a sash structure in which a shoji slides in and out of a sash frame attached to an outdoor opening of a building. Particularly, the barrier free sash in which the upper surface of the lower frame is formed in a substantially flat surface is easy to clean and has excellent crime prevention. It relates to the lower frame structure.

The outdoor opening of a building is generally provided with a sash structure in which a frame is constituted by an upper and lower frame and left and right vertical frames, and a shoji slide is opened and closed inside the frame.
In this case, in the case of a barrier-free type sash structure in which the upper surface of the sash lower frame is formed flat, a slide groove is provided in the lower frame, and a hanging piece suspended from an internal or external shoji is fitted into this groove, the conventional rail Although it is difficult for dust to enter compared to the lower frame of the equation, it was necessary to remove and clean a part of the upper surface of the lower frame when removing the dust flowing into and accumulated in the groove over a long period of time.
For example, Japanese Patent Application Laid-Open No. 2002-227537 discloses a technique in which an eye plate material is divided and attached to the upper surface of a lower frame and removed by bringing the shoji to one side.
Moreover, although the upper surface flat member (eye plate material) is divided into right and left, a gap may occur between them due to processing variation or the like, and there is a risk of rattling, and an elastic piece is provided on the knob member provided at the end of the eye plate material, When the elastic piece presses the vertical frame side, the eye plate material is pressed against the shoji summon side, thereby preventing a gap from being generated between the eye plate materials.
However, because it is easy to detach and remove the eye plate material in this way, there is a concern that if the child pranks and removes the eye plate material and opens and closes the shoji screen in a state of being struck, the eye plate material and the shoji screen may be damaged. .
In other words, the eye plate material is pressed to the shoji summing position side by the elastic piece of the knob member provided at the end of the eye plate material, but the removal of the eye plate material is easy because the knob member and the recess for inserting the finger are provided. On the other hand, it was not enough to prevent children from tampering.
Further, if the structure is such that the eye plate material is screwed as a countermeasure, the screw portion may be damaged by repeated attachment and detachment of the eye plate material.

As shown in Japanese Patent Laid-Open No. 2002-227537, FIG. 1 (c), the second member 2a for the shingles with the shoji screen closed and without the shoji screen is removable from the outside, and is stolen or lost. There was a worry.
The invention according to Japanese Patent Laid-Open No. 2002-22753 was mainly intended for sashes for buildings such as condominiums, but it is preferable from the viewpoint of crime prevention that it can be easily removed from the outside when deployed for general housing. Absent.

Japanese Patent Application Laid-Open No. 11-280343 discloses a technique in which an elastic protrusion provided on a removable step member of a lower frame is fitted and fixed between guide-like engagement pieces.
Japanese Patent Laid-Open No. 11-131929 discloses a technique in which a latch is provided at an end of an attachment (upper surface member of a lower frame) and a receiving portion is provided in a lower frame or a vertical frame to mount the attachment.
However, these techniques are not sufficient from the viewpoint of preventing mischief of children because they can be easily removed without removing the door.
Japanese Patent Application Laid-Open No. 2001-214669 discloses a structure in which a hole is provided in an inclined cover (upper surface member of the lower frame), and a driver or the like is inserted into the hole and lifted and removed.
However, this technology is a technology for attaching a bathroom floor with a step and an inclined cover provided outside the sliding door to prevent the floor surface of the dressing room from tripping. The upper surface of the lower frame is made flat and the shoji opens and closes. It is different from the mounting structure of the lower eye plate material.
In any case, the techniques disclosed in Patent Documents 2 to 4 relate to a bathroom, and the lower frame structure itself is different from an outdoor sash that requires high watertightness.

The lower frame recess under the slide groove also has a function of temporarily storing rainwater and the like, but the rainwater stored in the lower frame recess is splashed by projecting the fin from the side wall of the eye plate material. Can be prevented.

The technical gist of the invention described in claim 2 is that when the shoji is located above the eye plate material by projecting the fin portion beyond the vertical position of the orbit of the shoji hanging pendulum piece, This is because it is difficult to remove the eye plate material due to interference of the fins.

The technical gist of the invention described in claim 3 is that when the shoji is fully opened and the eye plate material is removed, the fin portion on the shoji summing position side is within a range in which the fin portion does not interfere with the hanging piece under the shoji. The notch is provided.

Even when the shoji is fully opened, for example, it is often restricted by the stopper for the purpose of protecting the crescent and the like is left behind.
In order to prevent interference with the hanging piece of the remaining portion when removing the eye plate material, the vicinity of the shoji summing position of the fin portion is cut out.

The technical gist of the invention described in claim 4 is that when the shoji is closed, an engaging portion is provided between the second member of the outdoor side plate material and the lower frame or the vertical frame. The engagement portion cannot be released unless the outdoor side plate material second member is slid a predetermined distance to the summoning side.

An engagement part is provided between the lower frame or the vertical frame, and the engagement part cannot be released unless the outdoor side plate material second member is slid a predetermined distance to the summoning side. When the engaging portion is provided, a hook-like engaging portion is provided in the outdoor side plate material second member, and the engaging portion is inserted into a hole provided in the lower frame.
Then, the hook portion of the bent end of the engaging portion is hooked on the edge of the hole when the outdoor side plate material second member is lifted upward from the attached state to the lower frame, but the outdoor side plate material second member is When it slides to the summoning side for a predetermined distance, the collar part is released from the edge of the hole and the engagement is released, so that the outdoor side plate member second member can be removed upward.

Moreover, when providing an engaging part between vertical frames, it is set as the structure inserted in the hole provided in the vertical frame, for example by providing the protrusion part which protruded in the vertical frame side from the outdoor side plate material 2nd member.
Thus, unless the outdoor side plate material second member is slid to the summit side for a predetermined distance, the projecting portion does not come off the hole of the vertical frame, and the outdoor side plate material second member cannot be removed.
In this way, the outer side eye plate material second member is structured so that it cannot be removed unless the second side member is slid to the summit side for a predetermined distance, so that the other side eye plate material of the outdoor side eye plate material second member is removed first, As long as the outer side plate material second member is not slid, the outdoor side plate material second member can be prevented from being removed.

The technical gist of the invention described in claim 5 is that when the shoji is closed, the outdoor eye plate material first member having the shoji on the upper portion is removed, and the eye plate material first member is removed upward between the lower frames. However, it is the point which provided the engaging part which cannot be slid in the direction of the shoji summon position.

Between the outdoor outer plate material first member and the lower frame, to provide an engaging portion that can be removed upward, but cannot slide in the shoji summing position direction, for example, A projection is provided on the first member of the eye plate material, a hole is provided in the lower frame, and the first member of the eye plate material is attached to the lower frame so that the projection and the hole are fitted together.
Then, even if it is going to slide the outdoor side board material 1st member in the direction of a shoji summon position, protrusion protrudes in a hole. On the other hand, when the eye plate material first member is lifted upward, the projection can be removed from the hole and the eye plate material first member can be removed.
Even when the shoji is located above the outdoor first plate member in the state in which the shoji is closed, and the upper removal of the first plate member is prevented, the first plate member is divided. If the mating eye plate material is removed, the first eye plate material first member may be slid to a position where there is no shoji above the shoji summing position direction and may be removed.
Therefore, it is possible to prevent the outdoor-side eye plate material first member from being slid and removed by regulating the slide in this way.

The technical gist of the invention described in claim 6 is that a center member of the eye plate material is fixed between the first member of the outdoor eye plate material and the second member of the outdoor eye plate material, or a slight movement allowance is provided in the longitudinal direction of the eye plate material. It is a point attached.

Removal of the outdoor side plate material first member by sliding it to the right side is a slight movement in the state of fixing the central plate material between the outdoor side plate material first member and the outdoor side plate material second member or in the longitudinal direction of the plate material It can also be prevented by installing a margin.
By providing a slight movement allowance in the longitudinal direction of the eye plate material, the eye plate material central member has an effect of moving slightly when removing the eye plate material and making it easy to remove.

In the lower frame structure of the lower frame flat sash according to the present invention, the lower part for drainage in the slide groove is provided by providing the fin part protruding from the side wall of the eye plate material to the lower side of the track of the shodder lower hanging piece. The frame recess is not visible from the outside.
As a result, it is not necessary to paint the lower frame recess, and the bottom depth of the slide groove is felt to be shallow, so that the flatness of the lower frame is increased and the appearance design of the lower frame is improved.
Further, this fin portion can prevent the rainwater from splashing from the lower frame recess that temporarily stores rainwater or the like.
This fin portion protrudes beyond the vertical position of the track below the hanging piece under the shoji, so that it is difficult to remove the eye plate material having the shoji on the upper side due to interference with the hanging piece fin.
In addition, by providing an engagement portion with the lower frame on the outdoor side plate material or by providing a central member of the plate material between the outdoor side plate materials, it is possible to remove the second outdoor member of the outdoor side plate material that does not have a shoji upward. Even if this outdoor side plate material second member is removed, the outdoor side plate material first member cannot be slid and can be prevented from being removed.
In this way, the eye plate material cannot be removed when the shoji is closed, and it is excellent in crime prevention.
