Description

The present invention relates to a curtain member for attaching a curtain to an opening of a tent installed outdoors or the like.

BACKGROUND ART Conventionally, in tents installed outdoors, etc., curtains have been used to open and close openings serving as entrances and exits of the tent. This curtain is provided with a curtain core material that has a certain degree of strength so that it is not pushed into the tent by wind. For example, in the curtain member (curtain structure) disclosed in Patent Document 1, two rail members are provided to slidably hold the curtain core material in the longitudinal direction. These two rail members (specifically, the rail and the auxiliary rail) are fixed to a frame portion around the opening of the tent. Furthermore, the two rail members are arranged parallel to each other at a predetermined interval on the upper end side of the curtain core material. The curtain core material is connected at its upper end to two rail members arranged in parallel. That is, since the curtain core material is connected to the rail member at two connection points spaced apart in parallel, the curtain is held so as not to be pushed into the tent by the wind.

However, since the two rail members are arranged parallel to each other at a predetermined interval on the upper end side of the curtain core material, the width of the curtain member in the thickness direction increases accordingly. This causes problems such as a reduction in storage capacity within the tent behind the curtain member, and problems such as the curtain member being bulky and interfering with other equipment.

JP2019-23384

Therefore, the present invention provides a curtain member that can be firmly held to prevent the curtain from being pushed into the tent by the wind while reducing the width in the thickness direction of the curtain member.

In order to solve the above problems, the curtain member of the present invention is a curtain member for attaching a curtain at an opening of a tent, and includes a curtain core material that holds the curtain and extends in a vertical direction, and a curtain core material that holds the curtain and extends in the vertical direction. A long first rail member and a second rail member that can be slid in the horizontal direction; and a first rail member and a second rail member that are fixed to a frame portion around the opening of the tent, and a rail fixing member to be attached, a first connecting member slidably connected to the first rail member is provided on the upper end side of the curtain core, and is spaced downward from the upper end of the curtain core. The section is characterized in that it is provided with a second connecting member slidably connected to the second rail member.

According to the above feature, the curtain core material is connected to the first rail member and the second rail member by two connection points (that is, the first connection member and the second connection member) that are vertically spaced apart and lined up in the vertical direction. connected. Therefore, compared to the conventional case in which the rail member is connected to the rail member by two connection points spaced apart in parallel, in the curtain member of the present invention, the two connection points are lined up in the vertical direction. This allows the width in the thickness direction around the connection point to be narrowed. As a result, problems such as a reduction in storage capacity inside the tent behind the curtain member and problems such as the curtain member being bulky and interfering with other equipment, etc. do not occur.

Further, when the curtain is pushed backward by wind from the outside, a backward pressing force (moment) is applied to the curtain core material. However, the curtain member of the present invention is connected to the first rail member and the second rail member by two connection points (that is, the first connection member and the second connection member) that are vertically spaced apart and lined up in the vertical direction. Because of this, it can withstand more pressing force (moment) than conventional products. As a result, the curtains can be held tightly to prevent them from being pushed into the tent by the wind.

Furthermore, the curtain member of the present invention is characterized in that the first rail member and the first connecting member are arranged on the back side of the rail fixing member.

According to the above feature, external force such as wind applied to the front side of the rail fixing member is prevented from being applied directly to the first connecting member or the first rail member.

Furthermore, in the curtain member of the present invention, the first connecting member is connected to the first rail member so as to be suspended in a vertical direction, and the second connecting member is connected in a direction perpendicular to the vertical direction. The second rail member is connected by rollers that sandwich and abut a part of the second rail member from both sides.

According to the above feature, since the first connecting member is connected to the first rail member so as to be suspended in the vertical direction, the first connecting member is able to absorb the vertical force of the curtain core material (for example, the self-weight of the curtain core material). ) can be strongly supported. Furthermore, since the second connecting member is in contact with the second rail member in a direction perpendicular to the vertical direction so as to sandwich a part of the second rail member from both sides, the second connecting member is prevented from moving backward due to external forces such as wind. It can strongly withstand the pressing force (moment) of In this way, the curtain member can sufficiently and strongly withstand the force in the vertical direction of the curtain core material and the force in the direction orthogonal to the vertical direction, respectively, by the first connecting member and the second connecting member. This is possible.

Furthermore, the curtain member of the present invention is characterized in that an auxiliary fixing member is provided on the back side of the rail fixing member, the auxiliary fixing member being obliquely fixed to the frame portion from a location adjacent to the first rail member. do.

According to the above feature, even if stress due to external force is applied to the rail fixing member and the first rail member, the auxiliary fixing member firmly supports the rail fixing member and the first rail member.

The curtain member of the present invention can reduce the width in the thickness direction of the curtain member while firmly holding the curtain so that the curtain is not pushed into the tent by wind.
