Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a Pilates bed with adjustable armrest angle. Background Technology

[0002] The Pilates bench is a common piece of equipment in Pilates training. During stretching and extension movements, it helps open up joints in the shoulders, neck, and hips, improving stiffness and flexibility. Targeted training using a Pilates bench can also correct issues such as rounded shoulders, hunchback, and anterior pelvic tilt, resulting in a more upright posture. The armrest angle can be adjusted to suit different movements and user groups.

[0003] The existing handrail angle adjustment structure fixes the handrail by setting arc grooves of different angles on the fixed plate. This fixing method requires the use of equipment such as laser engraving machines to process the arc grooves on the upper part of the fixed plate, which increases the processing cost. In addition, the arc grooves on the fixed plate are prone to causing the fixed parts to fall off, resulting in the handrail not being firmly fixed. Utility Model Content

[0004] To address the technical problems of high processing costs and unstable armrest fixing in existing technologies for armrest angle adjustment structures, this utility model provides a Pilates bed with adjustable armrest angles.

[0005] The Pilates bed with adjustable armrest angle provided by this utility model adopts the following technical solution:

[0006] A Pilates bed with adjustable armrest angle includes a foldable frame and a bed body supporting the human body located on the upper part of the foldable frame. It also includes armrests disposed on the upper part of the bed body. The bottom of the armrests is rotatably connected to the foldable frame through an angle adjustment component. The angle adjustment component includes a fixing plate fixed to the side of the foldable frame, and the edge of the fixing plate is provided with a plurality of angle bolts that can engage with the bottom of the armrests.

[0007] Furthermore, a support column is provided on the upper part of the bed, protruding upwards.

[0008] Furthermore, a lifting rope is slidably installed at the bottom of the bed.

[0009] Furthermore, the specific structure of the handrail includes a connecting plate disposed on the side of the foldable frame and a handrail disposed on the top of the connecting plate. The bottom of the connecting plate is rotatably connected to the foldable frame through an angle adjustment component.

[0010] Furthermore, the fixing plate has mounting holes, and fixing bolts are provided in the mounting holes. The bottom of the connecting plate has a long groove, and the fixing bolts pass through the long groove in the connecting plate and the mounting holes in the fixing plate and are screwed onto the side wall of the foldable frame.

[0011] Furthermore, a connecting pin is located near the long groove in the handrail, and a spring is connected between the connecting pin and the fixing bolt. Under the elastic force of the spring, the fixing bolt abuts against the upper side wall of the long groove.

[0012] Furthermore, a slot is located at the bottom of the connecting plate, and multiple fixing holes are evenly distributed at the edge of the fixing plate. Angle bolts that engage with the slot at the bottom of the connecting plate are installed in the fixing holes. After passing through the fixing holes, the angle bolts are screwed onto the side wall of the foldable frame. Under the tension of the spring, the connecting pin moves towards the fixing bolt, thereby driving the connecting plate to move in the direction of the angle bolt, so that the slot at the bottom of the connecting plate engages with the corresponding angle bolt in the fixing plate.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention features an angle adjustment component. During use, the user pulls the armrest outwards, separating the slot at the bottom of the connecting plate from the angle bolt. The armrest is then in a movable state. Rotating the armrest to a suitable angle and releasing the armrest causes the spring force to engage the slot with the corresponding angle bolt in the fixed plate, thus fixing the armrest's rotation angle. This structural design allows for quick angle adjustment, and the spring force ensures the slot sidewall always blocks the angle bolt, preventing it from slipping out and ensuring a secure position. Furthermore, during manufacturing, only multiple angle bolts need to be fixed to the edge of the fixed plate to achieve angle selection. This design is simple to manufacture, durable, and eliminates the need for machining multiple arc grooves on the fixed plate surface, saving manufacturing costs and improving the production efficiency of the Pilates machine.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example: Figures 1-4 The image shows a Pilates bed with adjustable armrest angles.

[0022] Reference Figures 1-4 As shown, this utility model discloses a Pilates bed with adjustable armrest angle, including a foldable frame 1, a bed body 3 supporting the human body located on the upper part of the foldable frame 1, a support post 31 protruding upward from the upper part of the bed body 3, and a lifting rope 4 slidably installed at the bottom of the bed body 3, allowing users to perform lifting exercises for various parts of the body using the lifting rope 4. It also includes armrests 2 installed on the upper part of the bed body 3, which support the user's hands during use.

[0023] Preferably, the handrail 2 has a specific structure including a connecting plate 22 disposed on the side of the foldable frame 1 and a handrail 21 disposed on the top of the connecting plate 22. The bottom of the connecting plate 22 is connected to the foldable frame 1 by an angle adjustment component 5 to form an angle-adjustable rotatable connection.

[0024] Reference Figure 2 and Figure 3 As shown, the angle adjustment assembly 5 includes a fixing plate 51 fixed to the side of the foldable frame 1. The fixing plate 51 has mounting holes 512, and a fixing bolt 53 is provided in the mounting holes 512. A long groove 23 is located at the bottom of the connecting plate 22. The fixing bolt 53 passes through the long groove 23 in the connecting plate 22 and the mounting hole 512 in the fixing plate 51, and is screwed onto the side wall of the foldable frame 1. This fixes the fixing plate 51 to the side of the foldable frame 1 and allows the connecting plate 22 to be rotatably mounted on the side of the foldable frame 1. A connecting pin 24 is located in the armrest 2 near the long groove 23. A spring 54 is connected between the connecting pin 24 and the fixing bolt 53. Under the elastic force of the spring 54, the fixing bolt 53 abuts against the upper side wall of the long groove 23.

[0025] Furthermore, the bottom of the connecting plate 22 has a slot 25, and multiple fixing holes 511 are evenly distributed at the edge of the fixing plate 51. Angle bolts 52 that engage with the slot 25 at the bottom of the connecting plate 22 are provided in the fixing holes 511. After passing through the fixing holes 511, the angle bolts 52 are screwed onto the side wall of the foldable frame 1. Under the tension of the spring 54, the connecting pin 24 moves toward the fixing bolt 53, thereby driving the connecting plate 22 to move toward the angle bolt 52, so that the slot 25 at the bottom of the connecting plate 22 engages with the corresponding angle bolt 52 in the fixing plate 51.

[0026] In use, the user pulls the armrest 21 outwards in the armrest 2, causing the slot 25 at the bottom of the connecting plate 22 to separate from the angle bolt 52. At this time, the armrest 2 is in an active state. Rotating the armrest 2 to a suitable angle and releasing the armrest 21 causes the slot 25 to engage with the corresponding angle bolt 52 in the fixing plate 51 under the elastic force of the spring 54, thus fixing the rotation angle of the armrest 2. This structural design facilitates quick adjustment of the armrest 2's angle by the user. Furthermore, the spring 54's tension ensures that the sidewall of the slot 25 always blocks the angle bolt 52, preventing it from slipping out and ensuring the armrest 2 remains in a constant position during use. During processing, only multiple angle bolts 52 need to be fixedly installed at the edge of the fixing plate 51 to achieve angle selection for the armrest 2. This design is simple to process, durable, and eliminates the need to process multiple arc-shaped grooves on the surface of the fixing plate 51, saving processing costs and improving the processing efficiency of the Pula tachys machine.
