Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a strike of a gate such as an accordion door that is expanded and contracted to open and close (hereinafter, simply referred to as a strike), and more particularly to a strike that has a simple structure and can reduce costs.
[0002]
[Prior art]
The present applicant has previously proposed a novel gate latching device and its locking device with registered model No. 2,126,822.
[0003]
As shown in FIGS. 1 and 2, the latching device includes a latch portion 3 attached to one of the gate 1 and the gate pillar 2 (the gate 1 in the illustrated embodiment), and the horizontal bar 4 attached to the other. (See FIG. 2).
[0004]
As shown in FIG. 2, the latch portion 3 includes a first and second pair of hooks 6 and 7, each having a hook-like portion that engages with the bar 4 of the strike.
[0005]
In addition, the hook-like portions at the tips of the first and second hooks 6 and 7 are arranged so that the tips are opposed to each other so that the outer edge forms a V-shape, and the hook-like portion is formed at the middle portion of the first hook 6. A long hole 9 opened in the first elongated connecting portion 8 that is projected substantially parallel to and integrally with the second connecting portion, and a second connecting portion that projects symmetrically with the first connecting portion 8 at the middle stage of the second hook 7. The pin 12 planted at the tip of 11 is engaged with each other.
[0006]
Furthermore, the first and second hooks 6 and 7 are rotatably supported at the base ends by the support shafts 13 and the elasticity of the hook springs 14 as torsion coil springs wound around the base end portions. The ends of the hook-shaped portions are urged in the direction of closing close to each other.
[0007]
The conventional latching device constructed as described above has a wedge action caused by the engagement between the bar 4 and the hooks 6 and 7 when the gate is closed, as shown by the chain line in FIG. The bar expands and the bar 4 passes through the hook-shaped portion of the hook, and then the hook is closed by the elasticity of the hook spring 14, so that the bar 4 is automatically held by the hook and the gate 1 is locked to the gate post. The

[Problems to be solved by the invention]
Of course, the conventional latching device described above is practically used with its functions reliably. However, as shown in FIG. 3, the strike 5 is applied to a strike frame 15 produced by pressing and bending a plate material. The bar 4 which is a drawing bar having a cross section of, for example, a heart shape (see FIG. 2) is joined by welding.
[0009]
Therefore, there is still room for improvement, such as the structure of the strike 5 becomes complicated and the manufacturing cost increases.
[0010]
Therefore, an object of the present invention is to provide a strike that has a simple structure and can reduce the cost.
[0011]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a substrate having a long and narrow plate-like body in the longitudinal direction, leaving a portion that later becomes a cross-sectional chevron, with both sides in the longitudinal direction sandwiching the central portion. the first the insertion slit is formed by pressing, then, a central portion in the length direction of the substrate, the cross-sectional shape by a fold line along the width direction thereof by Rukoto bent so as to Ryakuto shape, the substrate length A pair of parallel support leg plates and a cross-sectional chevron connecting the support base plates are integrally formed in the central part in the vertical direction, and the pair of L-shaped cross-sections sandwiching the cross-sectional chevron part in the central part in the width direction, The insertion slit is formed along the length direction of the substrate.
[0012]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
4 and 5, reference numeral 16 denotes a substrate, and the substrate 16 is an elongated plate having a rectangular outer shape.
[0013]
The substrate 16 is bent so that the cross-sectional shape is substantially a toroidal shape by a fold line along the width direction (paper surface direction in FIG. 4), and a pair of parallel supporting leg plates 17 and 17 at the center thereof, A cross-sectional angle portion 18 that connects these support leg plates 17 and 17 is integrally formed.
[0014]
Then, each of the pair of L-shaped sections 19 and 19 sandwiching the cross-sectional chevron 18 has an L-shaped cross-section insertion, leaving a cross-sectional chevron at one end and a solid part forming the end of the substrate at the other end. A slit 21 is formed.
[0015]
As shown in FIG. 5, the insertion slit 21 is preferably opened at the center in the width direction of the L-shaped section 19 and along the length direction of the substrate 16.
[0016]
Further, in the actual manufacturing process, a part that will later become a cross-sectional chevron 18 is left in the central part of the plate-like substrate, and insertion slits are first formed by pressing on both sides in the length direction across the central part. Then, it is better to perform the bending process later.
[0017]
As shown in FIG. 5, the strike according to the embodiment of the present invention configured as described above is screwed with a screw (not shown) to, for example, a gate pole 2 having an escape slit 22 having the same width as the insertion slit 21.
[0018]
In addition, by forming a recess in the joint with the strike on the gate column surface,
[0019]
In this mounted state, as is clear from FIGS. 2 and 5, the central part of the cross-sectional chevron 18 is in a floating state at the central part of the relief slit 22, and thus exhibits the same function as the conventional bar 4.
[0020]
It should be noted that the amount of protrusion of the cross-sectional chevron 18 from the surface of the gate pole can be changed by forming a recess in the joint with the strike on the surface of the gate pole or by adjusting the width of the support plate 17. The amount of gap between the gate post and the front plate of the latching device can be adjusted.
[0021]
FIG. 6 shows a modified embodiment of the present invention. In this embodiment, the top gate column 2 of the accordion gate running along the arrow A and the top gate column 2 of the accordion gate running along the arrow B are joined. Thus, the present invention is applied to a latch device for a gate when an L-shaped gate is formed.
[0022]
In this case, if the strike support plate 17 is lengthened, while the length of the substrate 16 is shortened (not shown) and most of the strike is stored in the gate pillar 2, the latching device and It looks good because the strike is not exposed.
[0023]
Therefore, the cross-sectional L-shaped portion of the strike is fixed to the inner surface of the gate column 2 by screwing or spot welding, and a horizontal relief slit through which the cross-sectional angle portion is inserted on the side surface of the gate column facing the hooks 6 and 7; It is preferable to open a cross-shaped slit (not shown) where vertical escape slits through which the hooks 6 and 7 pass are intersected.
[0024]
【The invention's effect】
As is apparent from the above description, the present invention is such that the substrate, which is an elongated plate-like body, is bent so that the cross-sectional shape is substantially T-shaped by a fold line along the width direction thereof, and the center in the length direction of the substrate. A pair of parallel support legs and a cross-sectional chevron connecting the support bases are formed integrally with each other, and the length of the substrate is at the center in the width direction of the pair of cross-sectional L-shaped parts sandwiching the cross-sectional chevron Since the insertion slit is formed along the direction, the entire manufacturing process of the strike can be pressed, and the manufacturing cost can be significantly reduced.
[0025]
In addition, since all the functional parts of the manufactured strike are coupled together, there are various effects such as an improvement in strength with high reliability.
