Description

Indoor clothespin

The present invention relates to a laundry bar that is mainly used indoors, between walls and columns installed in parallel, and can be easily attached and detached. Specifically, the present invention relates to an apparatus having all the following functions.
1, without a built-in compression spring for applying an urging force to the inside of the bar and bar-shaped member, using the weight of the laundry hanging on the clothes bar to stretch between the walls, the load on the wall It can be held between walls as a clothes bar while minimizing.
2. Stable even when there is no load (when the laundry is not suspended), and even when subjected to external force when hanging or removing the laundry, it will not come off easily and will always remain stable between the walls it can.
3. Even weak users, such as elderly people and women, can easily and reliably install and remove between walls, making it highly convenient as a product and excellent in productivity.

Even if the weight of the suspended object is light, the rod-shaped member or expansion / contraction pipe does not have a built-in compression spring for applying a biasing force to the wall, and is installed between the parallel walls using the weight of the suspended object. Patent application 2003-355664 (hereinafter referred to as an effective prior application) exists as a technique for indoor drying rods that can maintain stability and does not violate the laws of nature and is physically established.
However, in the content of the effective prior application, because it lacks the concreteness for practical use as a product, the specification of the product could not be determined, eventually it was difficult to use as an industry and was incomplete as an invention .
In addition, after reviewing previously filed documents, application documents with “similar pictures” were also found, but they all violate the laws of nature, and those skilled in the art are clearly aware of other documents. In other words, it was just a desk emptiness that could not be called a technology at all.
(Examples of prior applications that cannot be called technology: JP-A-8-131286, JP-A-11-333194, etc.)

Japanese Patent Application No. 2003-355664

The structure described in claim 1 of the effective prior application and shown in FIG. 1 of the effective prior application is highly likely to be theoretically established, but the detailed specifications are unclear for production development. , Could not produce and sell practical and realistic products. This problem is the main problem that the present invention is trying to solve.
That is, in order to practically use the technology of the effective prior application for industrial use, it is necessary to solve all the problems listed below with respect to the structure of claim 1 of the effective prior application.
There is no document that clearly states the following issues. Since the problem for practical use as an industry has not been clarified, naturally there is no existing technology for solving the problem other than the present invention .
1. If the inclination angle at which the abutment member slides is set several times with respect to the wall, it can be held between the walls by the weight of the suspended object, and the load on the wall is minimized. Unknown. That is, it is the most important subject of the present invention to clarify the device method and structure.
2. Since the rod-shaped member does not expand and contract and the contact member is always parallel to the wall surface, it is difficult to attach and detach between the walls. In addition, if the contact member is pin-coupled so that it can be “swinged simultaneously with the slide”, the contact member cannot be kept parallel to the wall surface and hangs down and cannot be attached.
3. The frictional resistance of the portion where the abutting member is slid is large, and the load conversion efficiency decreases. Also, when a pulley or the like is installed to reduce friction, the specific structure has not been clarified.
4. Regarding the structure in which the main body and the abutting member are connected by an elastic member, the optimum apparatus method and structure in consideration of the manufacturing cost and assemblability have not been clarified.
5. With the structure of the effective prior application, it does not look good and is not established as a product. In addition, it is structurally difficult to manufacture and assemble, and lacks function and consideration as a mass-produced product.
6. There is no safety device to prevent the product body and building walls from being damaged when an excessive load is applied.
7. The specific attachment / detachment method is unknown, and there is no consideration for easy attachment / detachment.

In order to solve the seven problems described in the previous section, each is configured as follows.
1. Equipment method that can be used as an industry, that is, it can be held between walls by its own weight, and in order to reduce the burden on the walls and pillars, the tension force on the walls is minimized, In order to ensure detachability, a very special inclination angle that maximizes the horizontal movable distance of the contact member is specified based on the law of nature.
2. The abutting member is pin-coupled so that it can swing up and down about 30 degrees, and the surface that is applied to the wall of the abutting member using a spring when no load is applied is almost parallel to the wall. Give power.
3. The frictional resistance is reduced by rolling the contact member along the oval through-hole using a pin. Further, the drive unit is configured to be thicker than the bearing unit, and is reliably rotated.
4. A small compression spring is installed inside the contact member, and at least one end is fixed to either the rod-shaped member side or the contact member side.
5. The abutting member is box-shaped and covers the small compression springs and bearings that are built in. Or, attach a cover on the back side to make the spring difficult to see.
6. Install a clutch on the screw that locks the expansion and contraction of the rod-shaped member so that the expansion / contraction part cannot be fixed beyond the specified tightening force. If the load of the suspended object exceeds the allowable value, the expansion / contraction part is slid. The main body is dropped from between the walls.
7. In order to facilitate attachment and detachment work, a grip for holding the contact member in a state where the overall width dimension is minimum is provided on both the contact member and the rod-shaped member.

Useful technologies that were theoretically established but lacked in concreteness and could not be used in the industry can be used effectively, and can be designed, manufactured, and sold as realistic products, greatly increasing the development of the industry. You can contribute. In other words, it is possible to obtain the effect as the purpose of the patent law (industrial development).
In addition, with existing tension rods with built-in strong springs, it was extremely difficult for elderly people and women to attach them to high places, but with the present invention, they can be easily attached and detached, and indoor drying rods could not be used until now. People can now provide indoor clothespins.

It is a front view of the present invention. When the product of the present invention is installed horizontally between opposing parallel walls, a view from the horizontal direction is defined as a front view. The product of the present invention has a symmetrical shape except for the thicknesses of the inner cylinder 1 and the outer cylinder 19 and the position of the telescopic lock device 20, and the left side from the center line 3 is symmetrical to the right side of the center line 3. Therefore, it is omitted. It is a longitudinal cross-sectional view of this invention, and only the right side part is described similarly to FIG. The movable part of the product of the present invention is cut vertically and viewed from the front direction, and shows a structure in which a spring 13 and the like are installed inside the contact member. FIG. 2 is a top view of the product of the present invention, and only the right side portion is shown as in FIG. 1. It is a cross-sectional view of the product of the present invention, and only the right side portion is shown as in FIG. The movable part of the product of the present invention is cut in the horizontal direction and viewed from above, and shows the structure of the rotating shaft, bearings, wheels, etc. installed in the contact member.

The mode for carrying out the present invention is as specified in claims 1 to 7. An example of that will be described with reference to FIG.
As shown in FIG. 1, the contact member 4 slides along an oval through hole 9 inclined at an angle 8. At this time, since the rollers 7 are installed on the holders 2 attached to both ends of the rod-shaped member 1, the abutting member 2 has less friction because the rollers 7 roll inside the oblong holes 9. Can move with resistance.
In the present invention thus constructed, when the angle θ shown in 8 is increased, the weight of the suspended object is converted into a force pushing the wall only slightly, so that the product of the present invention cannot be held between the walls.
On the other hand, if the angle is reduced, the force to push the wall becomes excessive. For example, even if only 10 kg is suspended, the wall is pushed by 100 kg and the wall of the house is destroyed. become.
Therefore, when the friction coefficient between the contact sheet 5 attached to the contact member and the wall 6 is μ, the relationship with the angle θ is “μ / tan θ ≧ 1”. . If the apparatus is configured so as to satisfy this relationship, the product of the present invention can be reliably held between the walls. In particular, if “μ / tan θ = 1”, the burden on the wall can be minimized. Even when the friction coefficient of the contact sheet 5 decreases with time, the angle 8 can be set with the decreased friction coefficient, and a practical product can be manufactured.
Moreover, since this calculation formula is established regardless of the load of the suspended object, the optimum state can always be maintained even if the weight of the suspended object increases or decreases.
For example, when the friction coefficient μ = 0.5, if the angle θ of 8 is set to about 26 degrees, it can be held between the walls, and the force pushing the walls only increases in proportion to the weight of the suspended object. The burden on the wall can be minimized. With existing struts that have a strong compression spring inside the telescopic pipe, regardless of the weight of the suspended object, the wall is always pushed with the maximum load, so there is a high possibility of breaking the wall. “The effect of reducing the burden on the wall according to the present invention” is extremely large and unprecedented.
The above is an example of the contents described in claim 1 of the product of the present invention.

2 is a cross-sectional view showing the inside of FIG. 1, FIG. 3 is a top view of the present invention, and FIG. 4 is a cross-sectional view of FIG. The internal structure of an example of the product of the present invention will be described using these drawings.
Holders 2 for attaching movable contact members 4 are attached to both ends of the rod-like member 1. The holder 2 may be integrally formed with the rod-shaped member 1. The holder 2 is provided with two stays 11 by integral molding. A bearing hole 18 is provided in the stay 11 and the shaft 12 is rotatably inserted. Mushroom-shaped rollers 7 are attached to both sides of the rotary shaft 12, and when this roller 7 is compared to a mushroom, a cylindrical portion 17 corresponding to the mushroom shaft rolls along an oval through hole. And the umbrella part of the mushroom is a stopper. That is, when assembling the product of the present invention, the stay 11 is covered with the contact member 4, the positions of the oval through hole 9 and the bearing hole 18 are aligned, the rotary shaft 12 is inserted, and the cylindrical portion 17 is inserted on both sides thereof. If the mushroom-shaped roller 7 having a pressure is fitted and attached, the contact member 4 can slide freely along the oval through hole. The rotating shaft 12 receives frictional resistance with the bearing hole 18, but the diameter of the cylindrical portion 17 that rotates the rotating shaft 12 is sufficiently larger than the diameter of the rotating shaft 12. The contact member 4 is not hindered from moving.

2 and FIG. 4 is a spring receiver for attaching a small compression spring 13. The end of the spring 13 is bent by placing the end of the spring on the plane of 15 and bending the plate-like hook 16. Installation is completed by holding 1 to 2 rolls.
Reference numeral 14 denotes a spring holder provided inside the abutting member 4. The spring holder 14 has a depth that allows the spring to be held so as not to move from a predetermined position by inserting one end of the spring 13.
When assembling the product of the present invention, as described above, the rotating shaft 12 is inserted by covering the stay 11 with the contact member 4. At this time, the other end of the spring 13 attached to 15 is inserted into 14. assemble.
By configuring as described above, the contact member 4 can freely slide along the oval through hole 9 inclined at an angle θ, but is always against the rod-shaped member 1 by the biasing force of the spring 13. The highest position, that is, the entire length of the product of the present invention is held longest.
Further, since the compression spring 13 is fixed at the lower end and the upper end is held by the holder 14 having a predetermined depth, it is possible to exert an elastic force against bending. For example, in the state of FIG. Even if the contact member 4 is rotated left and right around the rotation shaft 12, it always returns to the state shown in FIG.

With the above-described configuration, the contact sheet 5 attached to the contact member 4 is always held parallel to the wall, and the necessary minimum attachment is provided by the spring 13 even when there is no suspended object, that is, no load. Because the power is given to the wall, there is no wobbling and it is possible to hang laundry stably.
Further, when removing the product of the present invention, if one side of the rod-shaped member 1 is lifted, the contact member 4 compresses the spring 13, and the roller 7 having the cylindrical portion 17 moves to the top of FIG. The total length of the product of the present invention is shorter than the distance between the walls, and can be easily removed.
When the product of the present invention is attached between the walls, it can be easily attached by the reverse method to the above, and the contact member 4 can be rotated with respect to the rotary shaft 12, so Even if only one side is lifted and tilted, the contact sheet 5 can be moved up and down while maintaining a parallel state with the wall, and therefore does not hinder the attaching / detaching operation.
The above is an example of the contents described in claim 2 of the product of the present invention.

In order to solve the problem of the present invention and exhibit a predetermined function, the positional relationship between the stay 11 provided with the bearing and the oval through hole 9 may be reversed. That is, the bearing member 18 is provided with the bearing hole 18 and the oval through hole 9 is provided on the stay 11 side. Also in this case, the total length of the product of the present invention is always kept at the maximum by the spring 13, and the contact member 4 can slide at a predetermined angle θ, so that the problem can be solved reliably.
The above is an example of the contents described in claim 3 of the product of the present invention.

In order to solve the problem of the present invention and to exhibit a predetermined function, the spring 13 does not need to be a compression spring, and the problem can be solved even with a tension spring. In this case, in FIG. 2, the stay may be extended upward from the holder 2 and the contact member 4 may be pulled upward by a tension spring. In other words, since various structures can be selected, it is possible to increase the degree of freedom when designing products.
The above is an example of the contents described in claim 4 of the product of the present invention.

When the bearing hole 18 is a perfect circle and the clearance with the rotary shaft 12 is small, the contact member 4 cannot swing left and right with respect to the rod-like member 1 when viewed from above when attached. Therefore, when the user attaches between the walls, it is necessary that the wall 6 and the rod-shaped member 1 are completely perpendicular as viewed from above.
In other words, it is necessary for the user to accurately and surely make a right angle, which is very inconvenient, and if it is attached in a non-right angle state, one side of the abutting sheet 5 is lifted and cannot be brought into close contact with the wall 6, but a bearing An excessive bending stress is generated in the hole 18, and the roller 7 having the cylindrical portion 17 cannot roll smoothly.
Therefore, as an example of a method for solving this problem, the bearing hole 18 is formed in an oval shape so that a predetermined function can be exhibited even if the product of the present invention is slightly inclined at the time of attachment.
The above is an example of the contents described in claim 5 of the product of the present invention.

In order to solve the problem of the present invention reliably and to ensure the merchantability, the roller 7 having the cylindrical portion 17 needs to rotate reliably. This is because the weight of the suspended object cannot be converted into a force pushing the wall 5 unless the roller 7 is always in a rotatable state even when the contact member 4 is stationary.
This theory can be easily understood by those who have no knowledge of physics, as if a “heavy drum placed sideways on a slope” is supported from below so that it does not roll off.
To make a drum that is rolling down a slope stand still, you must hold the drum from the bottom. In this stationary state, the drum can does not rotate at all, but it must always be pushed from below. If the product of the present invention is compared to this state, the weight of the drum can corresponds to the weight of the laundry, the angle of the inclined surface corresponds to the inclination angle of 8, and the force that supports the drum can from the lower side corresponds to the force that pushes the wall To do.
Here, when the adhesive is poured between the drum and the slope, even if the supporting force from the bottom is reduced, the drum can not roll down, and once the adhesive has hardened, the drum can remain stationary even if the pushing hand is released. .
When the above “facts” are applied to the product of the present invention, the load of the suspended object can be converted into a force that pushes the wall if the part configured to be rotatable can rotate without resistance. When 12 is fixed to the bearing hole 18 or the cylindrical portion 17 and the oval through hole 9 are fixed, the force cannot be converted and cannot be held between the walls, and the product is not established. In other words, it cannot be used as an industry.
Therefore, as an example of a solution to this problem, in order to reliably rotate at the bearing 18 portion, the rolling surface inside the oval through-hole 9 and the surface of the cylindrical portion 17 are made rough to ensure that they do not slip. The driving force is applied. Further, when the abutting member rotates with respect to the axis of the rod-like member, the weight of the suspended object cannot be converted into a tension force. As a solution, an arrow 10 indicating the mounting direction is provided on the side surface of the contact member 4.
Further, as a means for further enhancing the merchantability, a portion having a slightly narrow width is provided on the upper part of the oval through-hole 9 so that the roller 17 is held lightly at the uppermost part, and the bar-shaped member is contacted with the roller. A handle, that is, a grip, is provided on the contact member, and the apparatus is provided so that it can be easily held in a state where the entire length is shortest when being attached or detached.
The above is an example of the contents described in claim 6 of the product of the present invention.

In the “existing tension bar” with a built-in strong compression spring, the maximum allowable load is determined by the strength of the spring force. That is, if a strong spring is installed, a heavy object can be suspended, and if the spring is weak, even if a light object is suspended, it can easily fall.
On the other hand, in the product of the present invention, since the tension force to the wall changes according to the weight of the suspended object, it is theoretically possible to suspend any heavy object. However, the force that pushes the wall becomes infinitely large and destroys the wall of the house, and the main body is also destroyed when the strength limit is exceeded.
Therefore, in order to make it a practical product, a safety device for preventing destruction is indispensable.
Therefore, in the present invention, the inner cylinder 1 and the outer cylinder 19 constitute a rod-like member, and a device 20 that locks expansion and contraction is provided.
The locking device 20 has a structure in which the inner cylinder 1 is tightened with a screw provided on the outer cylinder 19 and is locked with a frictional force. A sliding clutch is provided on the screw of the locking device 20 and the screw is rotated with a certain force or more. If you try to let it run, it will idle and you will not be able to tighten the screw with more force.
When the laundry or the like is suspended from the rod-shaped member of the present invention, the abutting member 4 pushes the wall 6 and the rod-shaped member tends to be shrunk by the reaction force. Since the expansion and contraction of the wall is locked, it can withstand the reaction force from the wall 6 and the product of the present invention can be held between the walls without falling. However, if the laundry is hung over a predetermined weight, the locking device 20 exceeds the limit of fixation by friction, the inner cylinder 1 slides into the outer cylinder 19 of the rod-like member, the overall length becomes shorter, and the wall is The pressing force becomes 0 and it falls.
As described above, according to the present invention, the house wall and the main body are not destroyed, and it is extremely safe. In addition, since an expansion-contraction part shrinks, receiving the frictional force of the locking device 20, a full length becomes short slowly. In other words, there is no danger because it does not fall at a stretch and falls slowly as if sliding between the walls.
In addition, because the product of the present invention is specialized for indoor use, even if the laundry is dropped at the same time that the product of the present invention is dropped, the bottom is not the ground, but the indoor floor. There is no worry about things getting dirty.
The above is an example of the contents described in claim 7 of the product of the present invention.
