The present general inventive concept relates generally to a carpet stretcher, and particularly, to a staircase carpet stretcher.
Installing a carpet on a staircase requires heavy labor and can be an incredibly time consuming, difficult job to perform. Furthermore, an improper carpet installation can lead to wrinkling of the carpet, resulting in an uneven distribution of the carpet and preventing a smooth aesthetically pleasing finish.
Typically, a carpet stretcher requires a knee of a user to strike a cushioned surface. Additionally, the carpet stretcher includes a carpet spike that connects to the carpet. The carpet spike pulls the carpet in response to striking of the cushioned surface with the knee of the user. The repeated application of force with the knee can be tiring.
Therefore, there is a need for a staircase carpet stretcher that facilitates installing the carpet on the staircase without using the knee of the user.
The present general inventive concept provides a staircase carpet stretcher.
Additional features and utilities of the present general inventive concept will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the general inventive concept.
The foregoing and/or other features and utilities of the present general inventive concept may be achieved by providing a staircase carpet stretcher, including a frame assembly, a manipulation assembly springingly connected to at least a portion of the frame assembly to facilitate gripping thereof, a first stretch bar assembly removably connected at a first end of the frame assembly to connect to a carpet of a staircase and move in response to compression of the manipulation assembly, and a second stretch bar assembly removably connected at a second end of the frame assembly to connect to the carpet and prevent movement of the frame assembly on the carpet.
The frame assembly may include a main frame, and a spring receiving portion disposed on at least a portion of the main frame.
The manipulation assembly may include a handle to facilitate gripping thereof, a spring connector perpendicularly disposed away from a first end of the handle with respect to a direction, and a spring connected at a first end to the spring connector and connected at a second end within the spring receiving portion to compress in response to compressing the handle, such that the first stretch bar assembly moves in a lateral direction away from the main frame.
The manipulation assembly may further include a tension adjuster movably disposed on at least a portion of a second end of the handle to decrease a height of the handle in response to rotating in a first direction, and increase the height of the handle in response to rotating in a second direction, and a handle connector disposed on at least a portion of the second end of the handle to connect the handle to the first stretch bar assembly.
The first stretch bar assembly may include a first lateral bar disposed on at least a portion of the manipulation assembly, and a plurality of first carpet spikes perpendicularly disposed away from the first lateral bar with respect to a vertical direction to connect to the carpet.
Each of the plurality of first carpet spikes may be removably connected to the first lateral bar.
The second stretch bar assembly may include a second lateral bar disposed on at least a portion of the frame assembly, and a plurality of second carpet spikes perpendicularly disposed away from the second lateral bar with respect to a vertical direction to connect to the carpet.
The first stretch bar assembly may be disposed on a first plane on the staircase and the second stretch bar assembly is disposed on a second plane on the staircase, such that the first plane is different from the second plane.
The staircase carpet stretcher may further include a compression rod removably connected at a first end to the frame assembly and removably connected at a second end to the manipulation assembly and the first stretch bar assembly to apply an application of force against the first stretch bar assembly in response to compressing the manipulation assembly.

The frame fastener 170 may removably connect the main frame 111 to the compression rod 150. More specifically, the frame fastener 170 may removably connect the compression rod 150 within the rod receiving groove 113 of the main frame 111.
The lateral bar button 180 may be disposed on at least a portion of the main frame 111. The lateral bar button 180 may be depressed to detach the second stretch bar assembly 140 from the main frame 111.
In operation, the first lateral bar 131 and/or the plurality of first carpet spikes 132 may be disposed on a first portion of the carpet 10 on a first plane of the staircase. The second lateral bar 141 and/or the plurality of second carpet spikes 142 may be disposed on a second portion of the carpet 10 on a second plane of the staircase different with respect to the first plane. Also, the first lateral bar 131 and/or the plurality of first carpet spikes 132 may be disposed at a higher elevation than the second lateral bar 141 and/or the plurality of second carpet spikes 142. In other words, the first lateral bar 131 and/or the plurality of first carpet spikes 132 may be disposed on a first step at a higher position than the second lateral bar 141 and/or the plurality of second carpet spikes 142 disposed on a second step at a lower position.
The handle 121 may be depressed to compress the spring 123 via the spring connector 122. The movement of the handle 121 may rotate the handle connector 125, such that the lateral bar 131 and/or the plurality of first carpet spikes 132 may move in a lateral direction away from the main frame 111.
As such, the carpet 10 may move in response to movement of the first lateral bar 131 and/or the plurality of first carpet spikes 132. Also, the movement of the handle 121 to compress the spring 123 may direct a force against the compression rod 150 that moves the first lateral bar 131 and/or the plurality of first carpet spikes 132. The compression rod 150 may use the hydraulic piston to provide a gradual movement of the first lateral bar 131 and/or the plurality of first carpet spikes 132, instead of the fixed rod which provides a reciprocal transfer of motion (i.e. instant) from the main frame 111 to the first lateral bar 131 and/or the plurality of first carpet spikes 132. Furthermore, the second lateral bar 141 and/or the plurality of second carpet spikes 142 may stabilize the main frame 111, such that plurality of second carpet spikes 142 may prevent movement on the carpet 10.
Accordingly, the first lateral bar 131 and/or the plurality of first carpet spikes 132 may move in the lateral direction away from the main frame 111 in response to depressing the handle 121.
Therefore, the staircase carpet stretcher 100 may facilitate installation of the carpet 10 on the staircase using only a hand of a user.
