Description

[Detailed Description of the Invention] This invention relates to a sliding door catch that is attached to the sliding window of the cabin of a small vessel such as a leisure boat to prevent the window from opening automatically when the window is closed.

Conventionally used sliding door catches have a metal shaft that swings the engaging claw onto the mounting base of the catch body, which is made of cast brass or other metal material attached to the window door, and a stainless steel coil spring is attached to this shaft. This gives elasticity to the engaging claw in the engaging direction, and a catching claw made of metal such as brass casting that engages with the engaging claw is fixed to the window frame.

The conventional catch described above has various problems as shown below.

That is, since it is made of metal, when used for ships, it corrodes quickly due to the salt content of seawater, loses its function and appearance in a short period of time, and needs to be replaced at an early stage, and is expensive.

Since the catch body is made of metal, if it is directly attached to a glass window and a shock is applied to the catch body during transportation or use, the glass may break starting from the attachment part of the main body.

This invention aims to eliminate the above-mentioned drawbacks of the conventional catch, and is made of plastic to obtain the conventional functions without using a metal spring.

That is, this invention consists of a catch main body having an engaging pawl that is swingable and attached to a mounting base fixed to a window or the like and has elasticity in the engaging direction, and a catch that is fixed to a window frame or the like. A catch comprising a catch receptacle that removably engages with an engaging pawl, wherein the catch body and the catch receptacle are made of plastic, and an oblique outward knob provided on the mounting base and a knob part integrated with the engaging pawl. After curing, a binder made of silicone sealant with strong elasticity is filled.

This invention has the above-mentioned configuration, and an embodiment thereof will be described in detail with reference to the accompanying drawings.

In the figure, 1 is a window frame, and 2 is a window door attached to the window frame 1 in a sliding manner, which in the illustrated example is a glass plate.

The window frame 1 is made of anti-corrosion coated aluminum or the like, and is fixed to the side wall 4 of the cabin via a synthetic rubber connector 3 which also serves as a gasket, as shown in FIG.

Reference numeral A denotes the catch body, which consists of a mounting base 5 made of plastic such as polyamide and an engaging claw 6 made of the same material.

Reference numeral 7 denotes a backing plate made of the same material as the mounting base 5, and has two bosses 8 as shown in FIG. This patch plate 7 is applied to the outside of the window 2 via a rubber packing 10 having a hole into which the boss 8 is fitted, and the boss 8 is fitted into the hole provided in the window 2.

The mounting base 5 of the main body A is attached to the inside of the window 2 via the same rubber gasket 11 as the gasket 10, and a set screw 12 made of stainless steel inserted into the insertion hole provided in the base 5 is screwed. Screw into tube 9 and fix.

The tip of the tongue piece 1 provided on the knob part 14 is attached to the mounting base 5.
into the horizontal hole 19 provided at the bottom of the recess 20.
Further, a recess 20 formed between the oblique outward knob 13 integrally provided on the mounting base 5 and the knob portion 14 integral with the engagement claw 6 is filled with silicone sealant.

This silicone sealant has strong elasticity even after hardening, and furthermore, after hardening, it becomes a binding material 15 that connects the knobs 13 and 14 together.

A catch receiver 16 is made of the same material as the catch body A, and a plurality of stainless steel set screws 17 inserted through a plurality of insertion holes provided at the base of the catch receiver are inserted into the window frame 1.
Fix it by screwing it into the screw hole provided in the.

In the above configuration, when the window 2 is closed, the engaging claw 6 of the catch body A and the claw of the catch holder engage with each other as shown in FIGS. 2 and 3, and the window opens due to vibration etc. This prevents it from opening.

Next, when holding both the knobs 13 and 14 and pressing inward, the engaging claw 6 will move against the binding material 1 as shown in FIG.
5 as a fulcrum and is removed from the claw of the catch receiver 16, so the window 2 can be opened freely.

Further, the engaging claw 6 that has rotated as shown in FIG.
When closing window 2, it will restore its elasticity.
The engaging claw 6 of the catch body A contacts the tip of the catch receiver 16 and engages with it while rotating.

Although the above embodiment is functionally the same as a conventional catch, it is not corroded by salt such as seawater. In addition, in the case of the embodiment, the threaded cylinder 9
is made of metal, but this threaded tube 9 is made of plastic such as the mounting base 5, the backing plate 7, the boss 8, and the seal 1.
0, 11, etc., so there is no risk of corrosion even if brass or the like is used. Also, the heads of the set screws 12 and 17 are exposed to the atmosphere,
It is made of stainless steel and can be coated with corrosion-resistant paint to increase its corrosion resistance.

As mentioned above, the catch of this invention has a catch main body and a catch receiver made of plastic, and the mounting base of the catch main body and the engaging pawl are connected using an elastic bonding material made of silicone sealant, so seawater There is no fear of corrosion even when exposed to salt such as salt, and the engaging pawl has sufficient elasticity even though no spring or shaft is used. Therefore, its functionality and aesthetics are maintained over a long period of time, and the number of parts is small because no shaft or spring is used.

In addition, during assembly, it is only necessary to fill silicone sealant between the knob provided on the mounting base and the knob of the engaging claw, so assembly is easier than with conventional springs, and silicone sealant is After hardening, it becomes a binding material that connects the knob and the knob portion, so there is no risk that the engaging pawl or the like will separate from the mounting base due to vibration.

Furthermore, since the main body of the catch is made of plastic, it has the unique effect of reducing the risk of the glass breaking even if an impact is applied to the main body when it is directly fixed to glass.

In addition to small ships, this invention can also be used for buildings, furniture, and various land vehicles.
