Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an opening holder for doors, etc. More specifically, it refers to doors used for entrances and exits of buildings and vehicles, building doors such as gates, cupboards, and windows, as well as doors for furniture, such as single- or double-swing doors (in this specification, these are collectively referred to as This product relates to an opening holder used for doors (referred to as doors).

[Prior art] As a conventional door opening degree retainer, for example,
There is one shown in the figure. This opening degree retainer D consists of a stay 53 rotatably attached to the door 51 side with a mounting bracket 52 and a stopper 55 fixed to the door frame 54 side. , the stay 53 slides through the hole in the stopper 55, and the stay 53 is fixed in the stopper 55 by turning the screw 56 in the opposite direction.

When in use, when the screw 56 is turned and the door 51 is pushed and pulled, the stay 53 follows suit and the door 51 is opened and closed.If the screw 56 is tightened at a position halfway between opening and closing, the stopper 55 is activated. Door 51 is held in its open and closed position.

There is also another conventional opening holder shown in FIG. This opening retainer E has an outer cylinder 61
The inner member 62 is inserted into the door frame 54 and the door 5, and both ends are attached to the door frame 54 and the door 5 by means of mounting fittings 63 and 64.
Each is fixed at 1. By slightly moving the locking member 65 in the front-back direction, the inserting member 62
You can make it stretchable or restrict its movement.

[Problems to be solved by the invention] In both of the opening holders D and E, the door 5 is only on the outside when viewed from the side where the opening holder is attached.
I can't open 1. This is because the opening holder itself gets in the way of opening and closing the door, and for many years the only way to open the door has been to face the direction where the opening holder is not attached.

By the way, doors are generally designed to open toward private spaces rather than highly public spaces. For example, as a general rule, doors from hallways should open to the inside, and doors from hallways should open to the inside. However, recently it has become extremely difficult to adhere to this principle in residential buildings due to space constraints.

Therefore, if there is an opening holder that allows the door to be opened in the direction to which the opening holder is attached, the degree of freedom in the design of the door and the entire building, etc., will be increased. As an example, if we consider attaching a screen door to the outside of an inward-swinging door, it is extremely difficult to attach the screen door because conventionally, an opening holder is attached to the outside surface of the inward-swinging door. However, this problem does not occur because the door opening degree holder of the present invention is attached to the inside of the door, opposite to the side where the screen door is attached.

In view of the above circumstances, it is an object of the present invention to provide an opening degree holder that allows the door to be opened to the side to which the opening degree holder is attached.

[Means for solving the problems] The opening degree holder for doors, etc. of the present invention is (a) an opening degree holder connected between a door frame and a door to adjust the opening angle of the door; , (b) the opening retainer is attached to an outer cylinder and an inner member inserted into the outer cylinder so as to be expandable and contractible and restrainable, and is attached to both ends of the opening retainer and fixed to the door and the door frame, respectively. Consists of two mounting brackets, (c)
The mounting bracket is a metal fixture with an L-shaped cross section that connects a flat part with a shaft insertion hole and an upright part with a screw insertion hole, and (d) both of the upright parts of the two mounting brackets are While facing in the same direction, the flat part of one mounting bracket is pivoted to the upper surface of one end of the position retainer, and the flat part of the other mounting bracket is attached to the lower surface of the other end of the position retainer. (e) is fixed substantially flush with the upper or lower edge of the door; and (f) the opening retainer is configured to be pivoted within the swing range of the door. It can be installed in a position where it cannot be used.

Note that the door frame refers to the various frames mentioned above.

[Function] In the present invention, for example, if the opening degree retainer is attached to the upper edge of the door, the following will occur. The upright part of the mounting bracket, in which the flat part is pivoted to the upper surface of one end of the opening position holder, is located on the side surface of the opening position holder. Further, the upright portion of the mounting bracket whose flat portion is pivoted to the lower surface of the other end of the opening position holder is located below the side surface of the opening position holder. Therefore, by fixing the upright part of the former mounting bracket to the door frame with screws, etc., and fixing the upright part of the latter mounting bracket to the door with screws, etc., the opening position retainer will be positioned above the upper edge of the door. I come to do it.

Therefore, in the present invention, even when the door is opened, the opening degree holder does not interfere with the door opening, so that it can be used to open the door on the side to which the opening degree holder is attached.

[Example] Next, embodiments of the present invention will be described.

Fig. 1 is a perspective view of a position retainer according to an embodiment of the present invention, Figs. 2 to 4 are a plan view, front view, and perspective view of the same embodiment in an installed state, and Fig. 5 is another embodiment. FIGS. 6 and 7 are explanatory views of the state in which the inner member is inserted into the outer cylinder, and FIGS.
The figure is a perspective view of the locking mechanism.

In Fig. 1, 1 is an opening retainer, 5 is an outer cylinder,
6 is an insertion member, and 7 and 8 are mounting fittings.

As will be described in detail later, the opening retainer 1 has an inner member 6 inserted into the outer cylinder 5, and is expandable and retractable. Further, by slightly moving the grip member 15 in the front and back direction, expansion and contraction of the insert member 6 can be restrained.

Mounting fittings 7 and 8 are attached to both ends of the opening retainer 1, respectively. One end is the proximal end of the outer cylinder 5, and the other end is the distal end of the inner member 6.

The mounting fitting 7 is a metal fitting having an L-shaped cross section, and consists of a flat part 31 and an upright part 32. A shaft insertion hole is bored in the flat portion 31, and the shaft 33 is inserted through the hole. A screw insertion hole 34 is bored in the upright portion 32.

The mounting bracket that is pivoted to the base end of the outer cylinder 5 is the fifth one.
It may be configured as shown in the figure. That is, a mounting portion 35 extends horizontally from the lower edge of the upright portion 32, and a screw insertion hole 34 is bored in the mounting portion 35. In this mounting bracket 7a, the mounting part 3 is attached to the bottom surface of the door frame.
5 and screw in the screw. Note that the term "metal fittings having an L-shaped cross section" referred to in the claims is a concept that also includes metal fittings having a shape such as the mounting fitting 7a.

The mounting fitting 8 is a fitting having an L-shape in cross section, and consists of a flat part 36 and an upright part 37. A shaft insertion hole is drilled in the flat part 36, into which the shaft 38 is inserted, and a screw insertion hole 3 is formed in the upright part 37.
9 is perforated.

Since this embodiment is mounted on the top of the door, the upright parts 32 and 37 of the mounting brackets 7 and 8 are all directed downward, and the flat part 31 of the mounting bracket 7 is pivoted on the top surface of the outer cylinder 5. The flat portion 36 of the mounting bracket 8 is pivoted to the lower surface of the insert member 6.

2 and 3 show a state in which the opening degree retainer 1 is attached. In the figure, 2 is the door;
3 is the door frame. The opening degree retainer 1 has a proximal end of an outer cylinder 5 fixed to the door frame 3 by a mounting fitting 7, and a distal end of an insert member 6 fixed to the door 2 by a mounting fitting 8. The upright portion 32 of the mounting bracket 7 is located on the side of the opening retainer 1, and the upright portion 37 of the mounting bracket 8 is located below the opening retainer 1, so that the opening retainer 1 body is located above the upper edge of door 2. Therefore, as shown in Figure 4,
Even when door 2 is opened, opening degree holder 1 does not interfere, so
It is possible to attach the opening degree holder 1 to the side where the door 2 is opened.

Next, the structure of the main body of the opening degree holder 1 will be explained. As shown in FIGS. 6 and 7, this outer cylinder 5
has a wide cross section over most of the longitudinal direction.
It is formed into a letter shape. Side walls 11 on both sides of the outer cylinder 5 extend straight in the longitudinal direction.
The upper edge 11a of 1 extends slightly inward.
The upper edge 11a has a proximal end (left side in the figure).
A first engaging portion 41 having a concave and convex shape is formed in a continuous range from the tip to the vicinity of the tip (right end in the figure).
Further, a second engaging portion 42 formed by a concave portion is formed at the tip portion 11c of the outer cylinder. The inner insertion member 6 is a long member of the same size as the outer cylinder 5, and has a cross-sectional shape and size that allows it to be inserted into the outer cylinder 5 in a flexible manner, and has a wide cross-section.

A first engagement member consisting of a plate spring 9 and a second engagement member consisting of a plate spring 10 are attached near one end of the insertion member 6. Engagement portion 9b of leaf spring 9
is designed to elastically engage with a first engaging portion 41 formed on the upper edge 11a of the outer cylinder 5. That is, the leaf spring 9 is bent inward when an external force is applied, and is able to overcome the crest of the first engaging portion 41 of the wavy side wall 11. Engagement portion 10 of leaf spring 10
b is bent into an arcuate shape, and is adapted to elastically fit into and engage with the second engaging portion 42 of the outer cylinder 5. Therefore, when the engagement part 10b of the leaf spring 10 engages with the second engagement part 42, the engagement does not come off easily, but if the window is held and moved by hand, the engagement can be released with normal force. Generates an engaging force. Further, when the window is opened by hand, the engaging portion 10b automatically snaps into engagement with the second engaging portion 42 when the window is opened to the maximum.

FIG. 8 shows the locking mechanism of the first engaging member. This locking mechanism locks or releases the engagement of the leaf spring 9 at any position within the outer cylinder 5, and includes an inner member 6 and a square tubular knob member 15 placed over the outer cylinder 5. is established between.

As shown in FIG. 8, the insert member 6
A first stopper 16 is formed by cutting out the bottom plate 6a of the inserting member 6 and bending it diagonally upward, and a second stopper 17 is formed by raising the bottom plate 6a upward slightly inside the stopper 16. is provided. A wedge 19 is formed on the inner surface of the box of the knob member 15. The wedge 19 is inserted between the two engaging portions 9b of the leaf spring 9,
This prevents the engaging portion 9b from bending inward. A convex portion 21 connected by a connecting piece 20 is integrally formed at the rear of the wedge 19. Note that the grip member 15 having the wedge 19 and the convex portion 21 is preferably integrally molded from synthetic resin, aluminum die-casting, or the like.

When the knob member 15 is moved to the left in the figure, the wedge 1
9 comes out from the leaf spring 9, the inner member 6 can freely expand and contract within the outer cylinder 5. When the knob member 15 is moved to the right in the figure, the connecting piece 20 is bent and the convex portion 21 passes over the second stopper 17. At this time, wedge 1
9 fits between the two engaging portions 9b of the leaf spring 9, and the leaf spring 9 is no longer bent, so that the engaging portion 9b remains engaged with the recessed portion of the side wall 11 of the outer cylinder 6. . Therefore, in this state, the leaf spring 9 is restrained at the position where it engages with the side wall 11 of the outer cylinder 5, and cannot freely expand and contract with respect to the outer cylinder 5.

When locked in this manner, the first engaging member (plate spring 9) is locked from engagement at any position on the outer cylinder, so the window can be held at any open position.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made without departing from the gist thereof.

[Effects of the invention] In the present invention, the opening degree holder can be attached even on the side where the door is opened, so the design of the door etc. becomes easy.
