Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a strap shoulder rest for hanging portable items such as cameras, tape recorders, video recorders, etc.

"Prior Art and its Problems" In the past, strap shoulder rests were made of rubber.
This rubber shoulder rest is movably attached to a strap and is used by the user by moving it to the area that corresponds to the shoulder or neck, for example.

However, this classic rubber shoulder rest is heavy, and it cannot be said to be excellent in terms of appearance, manufacturing cost, or usability.Especially as the above-mentioned carrying items are used as a kind of fashion, straps are not suitable. In today's world, where innovative designs are required, there are very few cases where they are used.

The conventional strap has a stopper for adjusting the length, but the stopper is exposed. Therefore, if this metal fitting comes close to the shoulder rest, it will come into direct contact with your body, such as your shoulder or neck, and the weight of the suspended object will be applied directly to your body through the metal fitting, causing unpleasant pain or injury. This will result in

However, conventional shoulder rests do not have any means for preventing the fasteners from touching the body.

``Purpose of the invention'' The object of the invention is to provide a shoulder rest that can house the fasteners so that they are not exposed to the outside and prevent them from touching the body.

"Summary of the invention" The present invention was made based on the above-mentioned awareness of the problem, and consists of forming a flat sheath-like body from a flexible material into which a strap can be inserted, and connecting the sheath-like body to one of its two ends. Set the width of one end to the width that allows the cavity to accommodate the fastener, the width of the other end to the width that allows the cavity to fit tightly with the strap, and the width between the two ends to the width of the ends. It is characterized by being wider than the

"Example of idea" The invention will now be described with reference to the illustrated embodiments.

FIG. 1 shows an overview of an embodiment of the present invention, in which a sheath-like body 11 through which a strap 20 can be inserted is shown.
It is made of flexible material. At one end (upper part of the figure) of the sheath-like body 11, there is a stopper storage part 15 whose outer width is set to width W1, and in the middle, the outer width is set to width W1.
A wide portion 16 having a width W2 wider than W1 is formed at the other end, and a narrow portion 17 having an external width W3 narrower than the width W1 is formed at the other end.

The cavity of the stopper storage section 15 accommodates the stopper 21.
It is designed to have a width, height, and length that can accommodate. Therefore, the stopper 21 can be stored in the stopper storage part 15, that is, in the shoulder rest 10, and hidden so as not to be exposed to the outside.

The width W3 of the narrow part 17 is set so that the inner dimension d of the hollow part is almost the same as the width W of the strap 20, and the two fit closely in the width direction so that there is no space between the strap and the strap 20. It is constructed so that an appropriate frictional force is generated. The length 1 of the narrow portion 17 is determined so that the frictional force acting between the narrow portion 17 and the strap 20 is an appropriate amount.

On the other hand, the wide portion 16 widens the contact area as a shoulder rest, has a width W2, and is connected to the fastener storage portion 15 and the narrow portion 17 by a smooth curve. This width W2 can be set freely, but is preferably set to about 1.5 to 3 times the width W1 of the narrow portion 17, for example.

The shoulder rest 10 of this embodiment can be used as a shoulder rest by inserting the strap 20 into the hollow portion 14 and moving it to an appropriate position.
In this embodiment, since the central part is the wide part 16, when the bag is worn on the shoulder, the area of contact with the shoulder is large, making it more difficult to slip. Also shoulder rest 10
It also becomes easier to hold when holding it by hand.

The sheath-like body 11 having such a fastener storage part 15, a narrow part 17, and a wide part 16 can be easily manufactured by, for example, a weaving process using a tape loom, especially if it is made of a bag-like fabric.

According to this embodiment having the above configuration, the stopper 21 is placed in the stopper storage part 15, that is, in the shoulder rest 10.
It can be stored inside and not exposed to the outside.

Moreover, since the sliding movement of the strap 20 is appropriately restricted by the narrow portion 17 at the other end, the stopper 21 does not come out naturally from the storage portion 15.

Figures 2 and 3 show an example of the cross-sectional structure of this embodiment in which the present invention is applied to a pile 13 installed, and is made of flexible materials such as cloth, nonwoven fabric, synthetic resin material, etc. An adhesive layer 12 is formed by applying an adhesive to the surface of a sheath-like body 11 made up of the above, and piles 13 are flocked to this adhesive layer 12.

This shoulder rest 10 has a flat hollow part 1 of a sheath-like body 11.
4 is inserted into the strap 20, and is used as a shoulder rest by freely sliding it to the required position. The inner dimension d of the hollow part 14 of the narrow part 17 is made substantially the same as the width W of the strap 20 so that an appropriate frictional force acts between the strap 20 and the shoulder rest 10.

Flocking is widely used in carpets and clothing. This technique, commonly called flocking, is
Electrostatic flocking is the best and has become mainstream, but its principle is to place a base fabric coated with an adhesive layer in an electrostatic field, and to
By applying an electric charge to the pile, the pile is pushed against the adhesive on the base fabric using the force of static electricity, and because the pile stands up, it has a cushioning effect, a fluffy feel, heat retention, and aesthetics. It will be done. Carpets and clothing take advantage of these properties.

This embodiment utilizes the friction increasing effect of standing pile and the excellent tactile sensation as a shoulder rest. For this reason, the pile 13 is preferably made of synthetic resin fibers such as polypropylene or nylon.
Further, good results can be obtained when the fiber length is approximately 0.3 mm to 2.0 mm. If it is less than 0.3 mm, the fibers are too short and the frictional force will not increase, and if it exceeds 2.0 mm, the flocked pile 13 will lie down in the used state, and the frictional force will decrease instead, and a good texture will not be obtained. .

Further, the sheath-like body 11 may be made of any of the above-mentioned materials as long as it has appropriate strength and flexibility and can be implanted with hair. It is preferable to use a woven fabric. Since the bag-like fabric does not have seams in the sheath-like body 11, it can be easily obtained with excellent appearance and strength at a low cost. For example, it is possible to construct the sheath-like body 11 by sewing cloth, but the cloth not only has seams, but also needs to be turned inside out after sewing so that the ears are facing inward.

According to this embodiment in which the pile 13 is flocked to the sheath-like body 11, an appropriate frictional force with these contact surfaces and a good tactile feeling can be obtained. It does not easily slip when worn over the shoulder or around the neck. Additionally, a shoulder rest that is thinner and lighter than conventional rubber shoulder rests can be obtained.
Furthermore, flocked piles can be made by applying and forming an adhesive layer using an appropriate adhesive using current adhesive technology, so that they can be used repeatedly even in harsh conditions such as cold and hot places or rain. Never falls off. Therefore, a shoulder rest that has an anti-slip function, has an excellent tactile feel, and is highly durable can be obtained at a low cost. Furthermore, since the color of the pile can be freely selected, it can easily be adapted to the latest fashions of strap belts.

Note that it is preferable that the flexibility of the main shoulder rest 10 is smaller than that of the strap 20, that is, that it is harder than the strap 20, in terms of its function as a shoulder rest.

``Effect of the invention'' As mentioned above, the shoulder rest of the strap of the present invention allows the stopper to be stored inside the shoulder rest, so even if the stopper comes near the shoulder rest where the weight of the suspended object is placed, it can be stored inside the shoulder rest. If you do so, the stopper will not come into direct contact with your shoulders, neck, etc., so you will not experience any discomfort or pain, and you will not injure your neck, hands, etc. by touching it.
