Description

Technical Field

[0001] The utility model relates to furniture, in particular to a ladder for climbing up and down a bunk bed, and an elevated bed structure using such a ladder. Background Art

[0002] A bed is an essential piece of furniture in people's daily lives. The bed board of a traditional bed is about dozens of centimeters above the ground to facilitate people getting on and off the bed and sitting on the edge of the bed. However, with the increase in population and the diversification of usage requirements, people have gradually manufactured different forms of beds such as double-decker beds and elevated beds. These beds are about 1.8 - 2 meters above the ground, making it difficult for people to directly get on and off the bed, and a ladder must be installed on the outer side of the bed frame. Currently, all the ladders for beds are of fixed structures, including two ways: vertically installed on the edge of the bed frame and inclined installation with a drawer at the bottom. The vertical ladder can save a large amount of space, but it is difficult to climb, especially not suitable for children; the inclined ladder is more convenient to get on and off, but it requires a large amount of space, which is contrary to the usage requirements, resulting in low practicality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a foldable ladder for a bed and an elevated bed structure to improve the convenience of getting on and off the bed, while saving the required space and improving practicality.

[0004] The foldable ladder for a bed described in the utility model includes two parallel struts arranged side by side. A number of treads are spaced and connected between the two struts. There are upper and lower folding rods that are U-shaped and arranged opposite to each other up and down. The middle parts of the U-shapes of the upper and lower folding rods are respectively hinged to the bed frame columns. The two ends of the upper folding rod are respectively hinged to the two struts; the two ends of the lower folding rod are respectively hinged with connecting rods, and the other ends of the two connecting rods are respectively hinged to the two struts, and the connection length between the lower folding rod and the connecting rod is greater than the length of the upper folding rod.

[0005] Further, a clamping groove that can be clamped on the bed frame column is provided on the inner side of the tread.

[0006] Further, the clamping groove of the tread can be tightly clamped and fixed to the bed frame column.

[0007] Further, a rubber pad is provided at the clamping groove.

[0008] Further, an anti-slip pad is provided on the top surface of the tread.

[0009] Further, the anti-slip pads are arranged on both sides of the top surface of the tread.

[0010] Further, the middle parts of the U-shapes of the upper and lower folding rods are respectively hinged to the inner sides of the bed frame columns.

[0011] Furthermore, a baffle is installed at the top surface of one of the lower folding rod and the connecting rod, and the baffle extends towards the top surface of the other one of the lower folding rod and the connecting rod.

[0012] The elevated bed structure of the present utility model includes a double-bed frame for two people. A bed frame column is provided in the middle of the outer side of the double-bed frame, and a folding climbing ladder for the bed is installed on the bed frame column.

[0013] Another elevated bed structure of the present utility model includes a bed frame for the user to lie on and bed feet installed at the bottom of the bed frame. A bed frame column is installed adjacent to one of the bed feet on the outer side of the bed frame; a folding climbing ladder for the bed is installed on the bed frame column.

[0014] For the folding climbing ladder for the bed and the elevated bed structure of the present utility model, the bed frame can be a single-bed frame or a double-bed frame. A bed frame column is installed adjacent to one of the bed feet on the outer side of the single-bed frame, and for the double-bed frame of the double bed, a bed frame column can be provided in the middle of the outer side. A folding climbing ladder for the bed is installed on the bed frame column; both ends of the support rod of the folding climbing ladder for the bed are used for support, and the tread rods are for foot climbing to form a traditional straight ladder. The straight ladder is placed on one side of the bed frame and is opposite to the vertical bed frame column. Upper and lower folding rods for driving the straight ladder to change its state are respectively hinged at the corresponding positions of the upper and lower ends of the bed frame column and the straight ladder; when the straight ladder needs to be used for climbing, the upper and lower folding rods rotate around the hinge points of the bed frame column to drive the straight ladder to move. At the same time, since the length after the lower folding rod at the lower end and the connecting rod are connected to each other is greater than that of the upper folding rod at the upper end, the straight ladder forms an inclined state from top to bottom after being unfolded. The bottom of the support rod abuts against the ground, and the tread rod at the top can abut against the side surface of the bed frame column, and the user can smoothly climb up and down the bed along the straight ladder; when not in use, by rotating the hinge ends of the upper and lower folding rods and the connecting rod, the straight ladder can be vertically attached to the side surface of the bed frame column to form a storage state. Thus, through the setting of this folding climbing ladder for the bed, not only can the convenience of use be effectively guaranteed, but also no additional space will be occupied, greatly saving the required space and improving its scope of application and practicability.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0024] The present invention provides a folding ladder for a bed.

[0025] The folding ladder for a bed in this embodiment includes two support rods 1 arranged side by side with each other, and a plurality of tread rods 2 are connected between the two support rods at intervals; there are also an upper folding rod 3 and a lower folding rod 4 which are U-shaped and arranged up and down relatively. The middle parts of the U-shapes of the upper folding rod and the lower folding rod are respectively hinged to the bed frame columns 10, and the two ends of the upper folding rod are respectively hinged to the two support rods; the two ends of the lower folding rod are respectively hinged with connecting rods 5, and the other ends of the two connecting rods are respectively hinged to the two support rods, and the connection length between the lower folding rod and the connecting rod is greater than the length of the upper folding rod.

[0026] As shown Figures 1-3 in the figure, both ends of the strut are used for support, and the tread bar is for foot climbing, thus connecting to form a traditional straight ladder. The straight ladder is placed on one side of the bed frame and is opposite to the vertical bed frame column (or the bed foot). At the relative positions of the upper and lower ends of the bed frame column and the straight ladder, there are respectively an upper folding rod and a lower folding rod for driving the straight ladder to change its state; when the straight ladder is needed for climbing, the upper and lower folding rods rotate around the hinge points of the bed frame column to drive the straight ladder to move. At the same time, since the length after the lower folding rod at the lower end and the connecting rod are connected to each other is greater than the upper folding rod at the upper end, the straight ladder forms an upper and lower inclined state after unfolding. The bottom of the strut abuts against the ground, and the tread bar at the top can abut against the side of the bed frame column, so that the user can smoothly climb up and down the bed along the straight ladder; when not in use, by rotating the hinge ends of the upper and lower folding rods and the connecting rod, the straight ladder can be vertically attached to the side of the bed frame column, thus forming a storage state.

[0027] For the folding climbing ladder for the bed, a card slot 21 that can be clamped on the bed frame column is provided inside the tread bar 2, which can not only make the straight ladder more stably abut against the bed frame column when tilted, but also enable the straight ladder to be more fully stored, further saving space. It can also clamp and fix the card slot 21 of the tread bar 2 to the bed frame column to prevent the straight ladder from loosening and accidentally falling off from the storage state. At the same time, a rubber pad (not shown) is provided at the card slot 21, thereby improving the clamping strength and also avoiding collisions and noises when the straight ladder is stored. In addition, anti-slip pads 22 can be provided on the top surface of the tread bar 2, for example, on both sides of the top surface, to improve the convenience and safety of the user's climbing.

[0028] For the folding climbing ladder for the bed, the U-shaped middle parts of the upper folding rod 3 and the lower folding rod 4 are respectively hinged to the inside of the bed frame column, which can reduce the occupation of the space outside the bed and also enable the straight ladder to be more fully stored on the bed frame column.

[0029] For the folding climbing ladder for the bed, a baffle 6 is installed at the top surface of one of the lower folding rod 4 and the connecting rod 5, and the baffle extends towards the top surface of the other of the lower folding rod and the connecting rod. For example, the baffle is installed on the connecting rod. When the lower folding rod and the connecting rod drive the straight ladder to unfold, the connecting rod and the baffle rotate relative to the lower folding rod until the baffle presses against the top surface of the lower folding rod, thus forming a positioning, which is beneficial to improving the stability of the straight ladder in the unfolded state and also improving the safety of the user's climbing.

[0030] The present utility model also proposes a structure of an elevated bed.

[0031] The elevated bed structure of this embodiment includes a bed frame 20 for the user to lie on and bed feet 30 installed at the bottom of the bed frame. A bed frame column 10 is installed adjacent to one of the bed feet on the outer side of the bed frame. There is also a folding ladder for the bed for climbing. The folding ladder for the bed includes two parallel struts 1, and a number of treads 2 are spaced and connected between the two struts. There are also upper folding rods 3 and lower folding rods 4 that are U-shaped and arranged opposite to each other up and down. The middle parts of the U-shapes of the upper folding rods and the lower folding rods are respectively hinged to the bed frame column 10, and the two ends of the upper folding rods are respectively hinged to the two struts. The two ends of the lower folding rods are respectively hinged with connecting rods 5, and the other ends of the two connecting rods are respectively hinged to the two struts, and the connection length between the lower folding rod and the connecting rod is greater than the length of the upper folding rod.

[0032] As Figure 8 shown, a bed frame column is arranged beside the bed feet on the right side of the bed frame, and the folding ladder for the bed is installed on this bed frame column. This structure is suitable for student beds in dormitories where there is a bed above and a study desk below. Although the bed frame column and the folding ladder for the bed occupy the space under the bed, a bookshelf can be set on the right side under the bed to minimize the impact.

[0033] The present utility model also proposes an elevated bed structure.

[0034] The elevated bed structure of this embodiment includes a double-bed frame 40 for two people to use. A bed frame column 10 is arranged in the middle of the outer side of the double-bed frame. There is also a folding ladder for the bed for climbing. The folding ladder for the bed includes two parallel struts 1, and a number of treads 2 are spaced and connected between the two struts. There are also upper folding rods 3 and lower folding rods 4 that are U-shaped and arranged opposite to each other up and down. The middle parts of the U-shapes of the upper folding rods and the lower folding rods are respectively hinged to the bed frame column 10, and the two ends of the upper folding rods are respectively hinged to the two struts. The two ends of the lower folding rods are respectively hinged with connecting rods 5, and the other ends of the two connecting rods are respectively hinged to the two struts, and the connection length between the lower folding rod and the connecting rod is greater than the length of the upper folding rod.

[0035] As Figure 1 shown, the double-bed frame contains two beds and can be used for two people to lie on. The adjacent part of the two beds is the common part, which is the middle of the outer side of the double-bed frame. Setting a bed frame column here can not only serve as one of the bed feet, but also be used to install the folding ladder for the bed. This kind of bed structure can better reduce space occupation and improve the convenience for users to climb.

[0036] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
