Description

Spider mosquito net etc.

The present invention relates to an improvement in the bottom of a mosquito net, a table cover, and the like, and more particularly, to a bottom of the mosquito net that can be easily expanded by a drawstring.

When expanding the mosquito net, etc., by pulling up the pull string and raising the bottom of the rope, one end is pivotally attached to the lower part of the bottom and the other end is pivotable in the middle of the main bone. The worn bones rotate outward and expand the main bone, but when the main bone and the backbone bone are folded, the pivotal joint between the bone and the main bone is pivoted between the bone and the lower ring. Pull the drawstring first when the joints of the support bone and main bone are closer to the inner side than the joints of the support bone and the bottom (on the shaft side). However, the receiving bone is stretched, or the cover hem is attached and the receiving bone does not rotate, so that it cannot be expanded. Therefore, the lower part of the main bone is expanded by hand and the receiving bone is rotated slightly outward. It had to be moved to loosen the hem of the cover before pulling the drawstring, and the operation was very troublesome.

Therefore, in order to solve this problem, conventionally, as shown in FIG. 2, when the main bone A and the receiving bone B are folded, the receiving bone B and the pivoting portion C of the main bone A become the receiving bone B and An inwardly bent portion E is formed in the vicinity of the end of the receiving bone B on the connection side with the main bone A so as to be positioned outward from the pivoting portion D of the lower wheel, and the main bone A when folded. The inner side of the contact with the bent portion E prevents the main bone A and the receiving bone B from being folded further.

However, bending all the receiving bones B is inefficient and has problems such as high manufacturing costs.

In view of the above, the present invention enables the mosquito nets to be expanded smoothly without extending the catch bones or the cover hems even when pulling the pull string when expanding the mosquito nets. It is intended to provide the bottom of the mosquito net.

In order to solve the above-mentioned problems, the bottom crocodile net of the present invention is made of an elastic member provided on the bottom of the bottom of the bottom through the bottom of the bottom of the bottom by inserting the bottom of the bottom of the bottom of the bottom with a pull string. By locking the body to the top of the upper crossbone, the main bone and one end of the main bone and the other end pivotally attached to the lower crossbone are expanded, and then released from the upper crossbone by releasing the lock. The bottom of the potter's wheel is used for a mosquito net, etc., where the main bone and the receiving bone are folded, and the main bone and the receiving bone are folded at a lower position than the elastic body. The stopper is configured to be positioned on the outside of the pivot joint between the receiving bone and the bottom ring, and the main bone and the receiving bone are folded so that the receiving bone is folded. When hitting the stopper, the receiving bone is rotated slightly outward and Rutotomoni, main rib also a state in which the lower is slightly opened, is characterized in that the expansion of the main ribs and the receiving bone is facilitated.

In addition, the present invention of the mole of the mosquito net is characterized in that the stopper is formed in a ring shape in the circumferential direction of the shaft portion of the kuromosa net of claim 1. is there.

By adopting such a configuration, when the main bone and the receiving bone are folded, the cheek mosquito net and the like are in contact with the stopper. It is located outward from the pivot, so that the receiving bone is slightly rotated outward, and the main bone is slightly open at the bottom, so that the hem of the cover can be attached. Therefore, when the pull string is pulled, the catch bone is not stretched and the cover hem is not caught, and the main bone and the catch bone are smoothly expanded, and the mosquito net is expanded.
In addition, it is preferable that the stopper has a ring shape because it is easy to manufacture and reliable.

According to the bottom of the invented mosquito net, the folded bone is slightly rotated outward and the main bone is slightly opened downward, so it is pulled like a conventional mosquito net. There is an effect that when the string is pulled, the receiving bone is stretched and does not rotate, or the hem of the cover is not attached and does not expand, so that it can be expanded smoothly.

In addition, the construction is simple because it only has a ring-shaped stopper on the shaft part of the bottom wheel, and it is not necessary to perform the process of bending one end of all the receiving bones as in the prior art. In addition to being good, the manufacturing cost is also low.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a partially omitted cross-sectional view showing a use state of a ladle such as a mosquito net of the present invention.

In the drawing, reference numeral 1 denotes a plastic top made of an upper body 1a and a lower body 1b. The upper body 1 a is formed by integrally forming a head 2, a neck 3 at the lower part of the head 2, and a collar 4 formed at the lower part of the neck 3. A through hole 5 is provided at the center.

The through hole 5 is provided with a screw groove 5b having an inner diameter larger than the inner diameter of the upper hole 5a on the lower inner peripheral wall excluding the upper hole 5a, and forms a step portion 5c at the boundary with the upper hole 5a. Further, following the screw groove 5b of the through-hole 5, the lower part thereof is formed as a tapered lower hole 5d spreading downward.

The lower body 1b is composed of a hollow shaft portion 6 through which a shaft portion of a lower arm, which will be described later, can be inserted, and a collar portion 7 for attaching a main bone integrally formed on the outer periphery of the lower portion of the hollow shaft portion 6. A screw 6b that is screwed into the screw groove 5b of the through hole 5 of the upper body 1a is provided in a part of the outer peripheral surface of the upper body 1a. Further, a step portion 6c is formed on the outer peripheral surface of the hollow shaft portion 6 above the screw 6b so as to abut the step portion 5c of the through hole 5 of the upper body 1a. Above the step portion 6c, the through hole 5 of the upper body 1a is formed. Is inserted into the upper hole 5a.

Both step portions 5c and 6c are formed such that a gap 8 is provided between the lower surface of the collar portion 4 of the upper body 1a and the upper surface of the main bone attachment collar portion 7 of the lower body 1b at the time of abutting.
The gap 8 communicates with the lower hole 5d of the through hole 5 of the upper body 1a. Therefore, when the hole peripheral part of the center part of the cover is attached, the peripheral part is not easily sandwiched by the presence of the lower hole 5d as well as the gap 8.

Further, the main bone attaching collar portion 7 has a main bone 9 formed in a thin rod shape with a flexible metal or synthetic resin, and the radial groove 7a provided in the main bone attaching collar portion 7 has an upper portion thereof. Are pivotally attached 10 via a wire or the like provided in the circumferential groove 7b of the main bone attaching collar 7 respectively.

Reference numeral 11 denotes a mesh-like cover, which is stretched around the main bone 9. A hole 12 is provided in the center portion of the cover 11, and the hollow shaft portion 6 of the lower body 1 b of the top 1 is inserted into the hole 12, and then the upper body 1 a is screwed into the hole 12 in the center portion of the cover 11. Install. The size of the hole 12 is smaller than the outer diameter of the collar part 4 and the main bone attaching collar part 7, and is large enough to allow the hollow shaft part 6 of the lower body 1b to be inserted. The skirt portion of the cover 11 is fixed to the lower end portion of the main bone 9.

Reference numeral 13 denotes a plastic armor, and a receiving bone attaching collar 15 is formed at the lower end of the shaft 14 that can be inserted into the hollow shaft 6 of the lower body 1 b of the upper wheel 1. An elastic engagement body 16 is provided in the upper side so as to freely enter and exit. The elastic engagement body 16 can be engaged with and disengaged from the upper surface of the head 2 of the top 1.

A ring-shaped stopper 17 is formed integrally with the shaft portion 14 in the circumferential direction of the shaft portion 14 at a position below the central portion of the shaft portion 14.
A number of metal or synthetic resin receiving bones 18 corresponding to the number of the main bones 9 are received by the radial ribs 15 a provided in the receiving bone attaching collars 15. Each is pivotally attached 19 via a wire or the like provided in a circumferential groove 15b of the bone attachment collar 15.
Further, the other end of the receiving bone 18 is pivotally attached 21 to a clasp 20 fixed to the main bone 9 so as to be rotatable.

When the receiving bone 18 is folded, it hits the outer periphery of a ring-shaped stopper 17 provided on the shaft portion 14 of the lower cross 13, and at this time, the pivotal attachment 21 portion between the receiving bone 18 and the main bone 9 is the receiving bone 18. The stopper 17 is configured so as to be located outward from the pivoting portion 19 of the lower cross 13 and the collar 15 for receiving the bone.
This means that the stopper 17 against which the intermediate portion of the receiving bone 18 that is linear hits is naturally located outward from the pivoting 19 portion of the receiving bone 18 and the lower cross 13 (the receiving bone attaching flange 15). Will be configured as follows.
Thus, when folded, the receiving bone 18 is slightly rotated outward, and the main bone 9 is also slightly opened at the lower portion, so that the main bone 9 and the receiving bone 18 can be easily expanded. It becomes.
In the figure, reference numeral 22 denotes a drawstring having one end fastened to the upper end of the shaft portion 14 of the bottom rail 13 and the other end fixed to the knob 23.

Next, in order to expand the mosquito net, if the pulling string 22 is pulled, the shaft portion 14 of the lower skull 13 rises, whereby the receiving bone 18 rotates outward and the main bone 9 expands. The upper portion of the shaft portion 14 is inserted into the hollow shaft portion 6 of the lower body 1b of the upper crossbone 1 and the elastic engagement body 16 is engaged with the upper surface of the head portion 2 of the upper crosspiece 1 so that the lower crosspiece 13 is It is fixed to the potter's wheel 1 and the mosquito net expands.

The folding of the mosquito net pushes the elastic engagement body 16 with a finger to release the locking, and if the shaft portion 14 of the lower skull 13 is pushed downward, the receiving bone 18 rotates at once due to the elasticity of the main bone 9 in the closing direction. Then, the armpit 13 is lowered and folded, and the receiving bone 18 hits the stopper 17 of the shaft portion 14 of the armpit 13 and stops.

Although the present invention has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention.
