Description

The present invention relates to a hammock stand for installing a hammock on the upper part of a bed in a general household.

As a conventional hammock stand, a hammock stand having a simpler structure that can withstand the tensile force of a hammock caused by a human load has been studied.

A conventional hammock stand will be described with reference to FIG. In FIG. 3, posts (2) are connected to both ends of a horizontal bar (1) placed on the ground, and a hammock (7) is suspended from the upper ends of the left and right posts (2). In order to reduce the bending stress of the horizontal bar (1) and post (2) against the pulling force from the hammock (7) applied when a person rides, the connection angle of the post (2) to the horizontal bar (1) is: It is designed obliquely from the vertical, close to the pulling direction from the hammock (7).

In FIG. 4, two combinations of the horizontal bar (1) and two posts (2) in FIG. 3 are arranged in parallel, the posts (2) are tilted inward, and the two sets at the upper ends of the front and rear posts (2). Are connected. The hammock (7) is suspended from the left and right connecting portions.

Conventional hammock stands are mainly designed for outdoor use, and there are hardly any prior art documents on hammock stands having a structure that takes into account effective use of space and convenience when used indoors, particularly in ordinary homes. A conventional hammock stand requires a large space for installation, which is a great disadvantage for indoor use in a general household.

SUMMARY OF THE INVENTION An object of the present invention is to realize a hammock stand with improved functions for efficient use of space and convenience at low cost in order to use a hammock indoors in a general household.

When a hammock is installed indoors in a general household, the best space is considered to be the upper part of the bed (sleeper) from the viewpoint of effective use of space and convenience.

When installing a hammock at the top of the bed with a conventional hammock stand, the horizontal bar (1) must be installed under the bed in the hammock stand with the structure shown in FIG. is there. In the hammock stand with the structure of FIG. 4, even if two horizontal bars (1) are installed on the outside of the bed, the post (2) is inclined inward, so the horizontal bar (1) is lengthened and placed on the outside of the bed. It is necessary to install the post (2), and an extra large space is required.

In FIG. 1 showing the hammock stand structure of the present invention, there is a framework structure in which the post (2) is vertically raised without inclining, and the upper ends of the opposite posts (2) are connected and fixed by a connecting bar (3). To do. Thus, as shown in FIG. 2, a hammock stand facility can be formed by increasing the space of the horizontal bar (1) and the post (2) with respect to the installation space of the bed (8).

In the hammock stand (FIGS. 1 and 2) of the present invention, if the hammock (7) is directly suspended from the connecting bar (3), a large bending stress is applied to the connecting bar (3), resulting in poor durability. Therefore, the connection point before and after the post (2) and the connection bar (3), that is, both ends of the connection bar (3) are connected by the chain (5), and the hook (6) is attached to the intermediate point of the chain (5). The hammock (7) shall be suspended. As a result, bending stress is not applied to the connecting bar (3), and durability equivalent to that of a conventional hammock stand can be obtained.

As described above, a hammock stand can be installed in an existing bed in a general home with a minimum increase in space, and the hammock can be used with the same durability as a conventional hammock stand.

The perspective view of the hammock stand of this invention. The perspective view which set the hammock stand of this invention to the bed. The perspective view of the conventional hammock stand example 1. FIG. The perspective view of the conventional hammock stand example 2. FIG.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows the overall framework structure, and a horizontal bar (1) is connected to posts (2) at both ends thereof. The connection angle is determined by durability and convenience against bending stress. Two sets of this structure are placed in parallel, and the upper ends of the opposing posts (2) are connected by a connecting bar (3). The front and rear horizontal bars (1) facing each other are connected by a reinforcing bar (4) to suppress distortion of the entire frame. The connecting point between the front and rear posts (2) and the connecting bar (3) facing each other is connected by a chain (5), and the hammock (7) is suspended at an intermediate point of the chain (5). The length of the chain (5) is determined by the durability against the pulling force from the hammock (7) and the degree of sag of the hammock (7).

FIG. 2 is a view in which the bed (8) is provided with the hammock stand of the present invention. The length of the connecting bar (3) is a value obtained by adding the installation amount of the horizontal bar (1) and the post (2) to the length of the bed (8) in the short direction. The longitudinal length of the entire hammock stand is adjusted to the longitudinal length of the bed (8).

Claims (1)

A post (2) is connected to both ends of a horizontal bar (1) installed on the ground, and the post (2) is inclined from the longitudinal axis of the horizontal bar (1) and in the longitudinal direction of the horizontal bar (1). Stands at an angle of 90 degrees from the orthogonal axis on the ground. Two sets of the combination of the horizontal bar (1) and the two posts (2) connected to both ends thereof are arranged in parallel, and the upper ends of the opposing posts (2) are connected by the connecting bar (3). Framework structure. The connecting point of both the post (2) and the connecting bar (3) facing each other is connected by a chain (5), and a hook (6) for hanging a hammock is provided at an intermediate point of the chain (5).
