JP4395852B2 - Umbrella (post tilt angle multi-stage displacement) 2a - Google Patents

Description

Installed on a support which supports the upright umbrella struts locking or fixed to, the present invention relates to an umbrella with a handle which in use state Ru come umbrella inclination angle out changes hold in the direction of the sun.

A tilt mechanism is provided at the tip of the umbrella rod that is held by hand so that the area of the umbrella when it is expanded can be used efficiently (for example, Patent Document 1). also for the displaced and held in, the support for supporting an upright state umbrella struts, by changing the bevel angle of inclination out hold in accordance with the position of the sun in a use state of installing the locking or fixed to There is a difference in that both hands can be used because it is used after being locked or fixed to the support.

  A flexible pipe or a combination of pipes that allows a person holding an umbrella in his / her hand to put it under the umbrella (for example, Patent Document 2). Most of the same parts as 3699315.

Patent registration NO 3699315 JP 08-70918 JP 07-72558 A

The tilt angle of the umbrella canopy can be moved according to the position of the sun, and the tilt angle can be maintained at the moved position in a state where it is locked or fixed to the support that supports the upright state of the umbrella column. given in the coolness of the intense heat of come good weather, in accordance with the change of the position of the sun due to the passage of time, the umbrella canopy part is both hands in that suit taste the coolness of the movement always shade the Shikae, further sudden rain It is a challenge to provide an umbrella that can cope with the situation.

  According to a first aspect of the present invention, a cylindrical body that covers the coupling portion is provided on a support column in which one member and the other member are coupled to each other so as to be adjustable in an inclination direction, and the coupling between the one member and the other member is performed. Provided is an umbrella having a mechanism provided with a holding part for holding a pillar inclination angle in multiple stages on an upper part of a cylindrical body covering the part.

  The umbrella canopy tilt angle can be moved according to the position of the sun, so it is cool and always in the shade during the daylight hours.

The feeling of coolness under the umbrella canopy is improved by attaching a sheet having at least one of light shielding, heat shielding, and properties to the canopy of the umbrella.

It has become possible to cope with sudden rain by adding waterproof properties to the light shielding and heat shielding properties of the umbrella canopy sheet.

The drawings of the present invention are enlarged and displayed so that details can be easily understood, and the solid line and the solid line are close to each other, and there are many cases where the solid line and the solid line become black when electronically transmitting in the figure. A part between the solid lines is expressed with a little wider or is expressed by one line, and there is an exaggerated part, and the dimension between the drawings is reduced and enlarged.

A support for supporting the upright umbrella struts, locking or the use state of fixedly installed, umbrella with Modified hold it mechanism inclination angle in multiple stages to the strut.

Examples of the canopy sheet material having light shielding properties include metal vapor-deposited film, aluminum sheet, carbon black film, aluminum vapor-deposited foamed polyethylene, and tent campus cloth. There are polyester non-woven fabric, packing impact cushioning material, foamed polyethylene, foamed polypropylene, tent campus cloth, etc., and waterproof materials such as waterproof cloth, light shielding, film that does not allow water to pass among heat shield materials, or There are nylon film, polypropylene film, vinyl film, etc., but there are many patented products in these sheet bodies, so use them after confirming that, or use patented and commercialized products. Need to use or do.

  In the tilt angle multi-stage change holding mechanism (2a part), one member (the convex part of 2a part or the concave part of 2a part) and the other member (the concave part of 2a part or the convex part of 2a part) are mutually coupled, A cylindrical body (3) that covers the part is provided, and a holding part that holds the column inclination angle in multiple stages is provided on the upper part of the cylindrical body that covers the coupling part of the one member and the other member (FIG. 11). (FIG. 12), an umbrella having a tilt angle multi-stage holding mechanism on a support (FIGS. 10 and 2a), and when the convex part of the 2a portion is in contact with the highest position in FIG. 13 (a)} when the convex portion of the 2a portion is in contact with the second highest position, the inclination angle is 25 ° {FIG. 13 (b)}, and the convex portion of the 2a portion is at the third highest position. When in contact, the inclination angle is 40 ° {FIG. 13 (c)}, and when the convex part 2a is in the lowest position, the inclination angle is 55 ° {FIG. 3 (d)} is the angle settings and the number of stages can be changed with freely setting the number and height of the setting and the holding portion of the width of the convex portion of the portion 2a.

Therefore, the operation of changing the inclination angle is linked to a member positioned on one of the members (the protrusion of 2a or the recess of 2a) and the other member (the recess of 2a or the protrusion of 2a). The column (1) is lifted in a direction close to an upright position, and the cylindrical body (3) covering the coupling portion is moved to a position where it is desired to be set and held, and the lifted column is simply held by the moved holding unit. The tilt angle can be easily displaced.

Claims (1)

A cylindrical body that covers the coupling portion is provided on a support column in which one member and the other member are coupled to each other so as to be adjustable in an inclination direction, and the cylindrical body covers the coupling portion of the one member and the other member. The umbrella which has a mechanism provided with a holding part for holding the inclination angle of the pillar in multiple stages on the top of the pillar.
