Problems solved by technology

[0006] However, the conventional holding mechanism has a problem that when the telescopic strut 3 is fully opened due to excessive external force such as a gust of wind, the strut stopper 6 is deformed.
In addition, since the protrusion 2a on the side of the strut insertion member 2 rubs and moves on the inner surface of the outer cylinder 1, abnormal noise may be generated.
Moreover, when fully opened, the convex portion 2a is locked by going over the locking protrusion 1a formed in the shallow groove 1b and abutting against the end of the shallow groove 1b, but when the convex portion 2a goes over the locking protrusion 1a, Excessive external force is required, and when the locking protrusion 1a is passed over with such an external force, it will violently abut against the end of the shallow groove 1b, resulting in a loud knocking sound such as a rattling, which may cause discomfort to people. to problems like discomfort

Embodiment approach 1

[0023] Such as image 3 As shown, the switch device 8 is composed of an outer cylinder 9, an insertion member 10 that is slidably inserted into the outer cylinder 9 in a nested manner, an engagement plate 11 fixed inside the outer cylinder 9, and a lower portion fixed under the insertion member 10. The plate spring 12 on the surface and the sliding member 13 provided at the rear end portion of the insertion member 10 are constituted.

[0024] Outer cylinder 9 is the member of strip made of aluminum, is flat substantially square cross-section (referring to Figure 4 (b)). Such an outer cylinder 9 has a substantially square cross-section (that is, the inside of the outer cylinder 9 is hollow) and is similar in shape to the sliding member 13 mounted on the rear end 3c of the insertion member 10 by means of fixing components such as rivets 13a. , and slightly larger than that, the sliding member 13 can slide (slid smoothly).

[0025] The insertion member 10 is made of aluminum,...

Embodiment approach 2

[0033] Also like the outer cylinder 9, it is preferable that the insertion member 10 maintains sufficient strength for use in a switchgear when a member formed by forming aluminum into a substantially square-shaped cross section by press processing is used. The above can be manufactured lightweight and inexpensively.

[0034] Such as Figure 6 As shown in (a) and (b), the inserting member 15 is in addition to only cutting out a gap at the end (that is, making a part of it roughly C-shaped) in order to fix the leaf spring 12. 10 with the same structure. By making the entirety of the insertion member 15 substantially square-shaped, the strength can be further increased compared to the substantially C-shaped insertion member 10 .

[0035] Below, refer to Figure 7 An example in which the switch device 8 of the present invention is attached to the door D and the frame member F will be described. A circular hole 17 for rotatably attaching an attachment member 16 for attaching t...

Embodiment approach 3

[0037] Such as Figure 8 As shown, the switch device 20 is composed of an outer cylinder 21, an inserting member 22 freely slidably inserted into the outer cylinder 21 in a nested manner, an engaging plate 23 fixed inside the outer cylinder 21, and a lower portion fixed under the inner inserting member 22. The leaf spring 24 on the surface and the slide member 25 provided at the rear end portion of the insertion member 22 are constituted.

[0038] The outer cylinder 21 is an elongated member made of stainless steel and has a flat substantially C-shaped cross section (refer to Figure 9 ). Such an outer cylinder 21 has a substantially C-shaped cross-section (that is, the inside of the outer cylinder 21 is hollow) slightly larger than the size of the sliding member 25 mounted on the insertion member 22, and can slide the sliding member 25 (sliding smoothly). ).

[0039] The insertion member 22 is made of stainless steel, and is composed of a main body 22a and a rear end ( F...

Abstract

An inexpensive and lightweight opening / closing device of door and the like with small number of components comprises a member shape holding mechanism in which an insertion member is not deformed even when the device is opened fully by an undue external force but exhibits a practical strength as an opening / closing device thus sustaining the full open state surely, and generation of strange sound from a latching mechanism can be prevented during the opening / closing operation and under full open state. The opening / closing device comprises an aluminum outer tube having a substantially square flat cross-section or a stainless steel outer tube having a substantially C-shaped cross-section, an aluminum insertion member having a substantially C-shaped flat cross-section or substantially square cross-section and inserted into the outer tube or a stainless steel interior member having a substantially C-shaped cross-section and inserted into the outer tube, an engaging plate provided on the base at the distal end of the outer tube, a leaf spring provided in the insertion member, and a sliding member provided at the rear end of the insertion member.

Description

technical field [0001] The invention relates to a switch device for a door leaf or the like. More specifically, it relates to a switch device for a door leaf or the like: the outer cylinder and the inserting member are made of aluminum or stainless steel, and the switch device for the door leaf or the like includes an engaging plate, a leaf spring and a sliding member; The combined plate is arranged on the bottom surface of the front end of the outer tube, and has a concave engaging portion, and the engaging portion has a wall extending along the width direction of the inserting member; the base of the leaf spring is fixed on the outer rear end of the inserting member part, the front end of the plate spring has an engaging piece extending along the width direction of the above-mentioned insertion member, and the engaging piece can be locked on the wall of the above-mentioned engaging part; the above-mentioned sliding member is arranged on the rear end of the above-mentioned in...
